You could define a mapping of air pressure to servo angle, for example:

def calc_angle(pressure, min_p=1000, max_p=1200):     return 360 * ((pressure - min_p) / float(max_p - min_p))  angle = calc_angle(pressure) 

This will linearly convert pressure values between min_p and max_p to angles between 0 and 360 (you could include min_a and max_a to constrain the angle, too).

To pick a data structure, I wouldn't use a list but you could look up values in a dictionary:

d = {1000:0, 1001: 1.8, ...}  angle = d[pressure] 

but this would be rather time-consuming to type out!

Your model is @Messages, change it to @message.

To change it like you should use migration:

def change   rename_table :old_table_name, :new_table_name end 

Of course do not create that file by hand but use rails generator:

rails g migration ChangeMessagesToMessage 

That will generate new file with proper timestamp in name in 'db dir. Then run:

rake db:migrate 

And your app should be fine since then.

The approach I would take is: when reading the chapters from the database, instead of a collection of chapters, use a collection of books. This will have your chapters organised into books and you'll be able to use information from both classes to present the information to the user (you can even present it in a hierarchical way easily when using this approach).

Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.

This will be a JRE and JDK package.

There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.

So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]

When you read() the file, you may get a newline character '\n' in your string. Try either

if UserInput.strip() == 'List contents': 

or

if 'List contents' in UserInput: 

Also note that your second file open could also use with:

with open('/Users/.../USER_INPUT.txt', 'w+') as UserInputFile:     if UserInput.strip() == 'List contents': # or if s in f:         UserInputFile.write("ls")     else:         print "Didn't work" 

I think you missed a equal sign at:

Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + "" + l, null, null, null, null);  

Change to:

Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + " = " + l, null, null, null, null); 

You're storing the .Text properties of the textboxes directly into the database, this doesn't work. The .Text properties are Strings (i.e. simple text) and not typed as DateTime instances. Do the conversion first, then it will work.

Do this for each date parameter:

Dim bookIssueDate As DateTime = DateTime.ParseExact( txtBookDateIssue.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture ) cmd.Parameters.Add( New OleDbParameter("@Date_Issue", bookIssueDate ) ) 

Note that this code will crash/fail if a user enters an invalid date, e.g. "64/48/9999", I suggest using DateTime.TryParse or DateTime.TryParseExact, but implementing that is an exercise for the reader.

The most important difference to be aware of is that with a stream opened in text mode you get newline translation on non-*nix systems (it's also used for network communications, but this isn't supported by the standard library). In *nix newline is just ASCII linefeed, \n, both for internal and external representation of text. In Windows the external representation often uses a carriage return + linefeed pair, "CRLF" (ASCII codes 13 and 10), which is converted to a single \n on input, and conversely on output.

From the C99 standard (the N869 draft document), §7.19.2/2,

A text stream is an ordered sequence of characters composed into lines, each line consisting of zero or more characters plus a terminating new-line character. Whether the last line requires a terminating new-line character is implementation-defined. Characters may have to be added, altered, or deleted on input and output to conform to differing conventions for representing text in the host environment. Thus, there need not be a one- to-one correspondence between the characters in a stream and those in the external representation. Data read in from a text stream will necessarily compare equal to the data that were earlier written out to that stream only if: the data consist only of printing characters and the control characters horizontal tab and new-line; no new-line character is immediately preceded by space characters; and the last character is a new-line character. Whether space characters that are written out immediately before a new-line character appear when read in is implementation-defined.

And in §7.19.3/2

Binary files are not truncated, except as defined in 7.19.5.3. Whether a write on a text stream causes the associated file to be truncated beyond that point is implementation- defined.

About use of fseek, in §7.19.9.2/4:

For a text stream, either offset shall be zero, or offset shall be a value returned by an earlier successful call to the ftell function on a stream associated with the same file and whence shall be SEEK_SET.

About use of ftell, in §17.19.9.4:

The ftell function obtains the current value of the file position indicator for the stream pointed to by stream. For a binary stream, the value is the number of characters from the beginning of the file. For a text stream, its file position indicator contains unspecified information, usable by the fseek function for returning the file position indicator for the stream to its position at the time of the ftell call; the difference between two such return values is not necessarily a meaningful measure of the number of characters written or read.

I think that’s the most important, but there are some more details.

What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.

I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)

In your test, you are comparing the two TestParent beans, not the single TestedChild bean.

Also, Spring proxies your @Configuration class so that when you call one of the @Bean annotated methods, it caches the result and always returns the same object on future calls.

See here:

• How does Spring @Configuration cache references to beans

You can use customValidity

$(function(){     var elements = document.getElementsByTagName("input");     for (var i = 0; i < elements.length; i++) {         elements[i].oninvalid = function(e) {             e.target.setCustomValidity("This can't be left blank!");         };     } }); 

I think that will work on at least Chrome and FF, I'm not sure about other browsers

It's likely that the download was corrupted if you are getting an error with the disk image. Go back to the downloads page at https://developers.google.com/appengine/downloads and look at the SHA1 checksum. Then, go to your Terminal app on your mac and run the following:

openssl sha1 [put the full path to the file here without brackets] 

For example:

openssl sha1 /Users/me/Desktop/myFile.dmg 

If you get a different value than the one on the Downloads page, you know your file is not properly downloaded and you should try again.

A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.

You need to use get_serving_url from the Images API. As that page explains, you need to call create_gs_key() first to get the key to pass to the Images API.

You need to use ScriptManager.RegisterStartupScript for Ajax.

protected void ButtonPP_Click(object sender, EventArgs e) {     if (radioBtnACO.SelectedIndex < 0)     {         string csname1 = "PopupScript";          var cstext1 = new StringBuilder();         cstext1.Append("alert('Please Select Criteria!')");          ScriptManager.RegisterStartupScript(this, GetType(), csname1,             cstext1.ToString(), true);     } } 

Your line:

img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

will draw a rectangle in the image, but the return value will be None, so img changes to None and cannot be drawn.

Try

cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.

So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.

Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.

The previous version, xlrd 1.2.0, may appear to work, but it could also expose you to potential security vulnerabilities. With that warning out of the way, if you still want to give it a go, type the following command:

pip install xlrd==1.2.0

The only one reason why you get some error like that, it's because your node version is not compatible with your node-sass version.

So, make sure to checkout the documentation at here: https://www.npmjs.com/package/node-sass

Or this image below will be help you, what the node version can use the node-sass version.

For an example, if you're using node version 12 on your windows ("maybe"), then you should have to install the node-sass version 4.12.

npm install [email protected]

Yeah, like that. So now you only need to install the node-sass version recommended by the node-sass team with the nodes installed on your computer.

This can also occur when using the wrong import (for example when using autoimport). let's take the MatTimePickerModule as an example. This will give an error message that is similar to the one described in the question:

import { NgxMatTimepickerModule } from '@angular-material-components/datetime-picker/lib/timepicker.module';

This should instead be

import { NgxMatTimepickerModule } from '@angular-material-components/datetime-picker';

I didn't want to upgrade react-scripts, so I used the 3rd party reinstall npm module to reinstall it, and it worked.

npm i -g npm-reinstall
reinstall react-scripts

I had this problem but didn't have a version conflict in my package.json.

My package-lock.json was somehow out of sync with package json though. Deleting and regenerating it worked for me.

I downloaded latest eclipse and tarted to use from here https://www.eclipse.org/downloads/packages/release/ which resolved my problem.

Within IntelliJ, open pom.xml file.

Add this section before <dependencies> (if your file already has a <properties> section, just add the <maven.compiler...> lines below to that existing section):

<properties> 
   <maven.compiler.source>1.8</maven.compiler.source> 
   <maven.compiler.target>1.8</maven.compiler.target> 
</properties>

This work's for me :

Let's, uninstall create-react-app globally by this command:

npm uninstall -g create-react-app

After that in your project directory:

npm install create-react-app@latest

At the last:

npx create-react-app my-app

For typescript :

npx create-react-app my-app --template typescript

brew switch openssl 1.0.2r

it work for me,macOS Mojave, Version 10.14.6

simple just change it to : const uuidv1 = require('uuid'); it will work fine.

We experienced this problem on pages with long Base64 strings. The problem occurs because we use CloudFlare.

Details: https://community.cloudflare.com/t/err-http2-protocol-error/119619.

Key section from the forum post:

After further testing on Incognito tabs on multiple browsers, then doing the changes on the code from a BASE64 to a real .png image, the issue never happened again, in ANY browser. The .png had around 500kb before becoming a base64,so CloudFlare has issues with huge lines of text on same line (since base64 is a long string) as a proxy between the domain and the heroku. As mentioned before, directly hitting Heroku url also never happened the issue.

The temporary hack is to disable HTTP/2 on CloudFlare.

Hope someone else can produce a better solution that doesn't require disabling HTTP/2 on CloudFlare.

You need to add the package containing the executable pg_config.

A prior answer should have details you need: pg_config executable not found

This appears to be a limitation in git-bash. The recommendation to use winpty python.exe worked for me. See Python not working in the command line of git bash for additional information.

I had this issue when I used npm link to install my local library, which I've built using cra. I found the answer here. Which literally says:

This problem can also come up when you use npm link or an equivalent. In that case, your bundler might “see” two Reacts — one in application folder and one in your library folder. Assuming 'myapp' and 'mylib' are sibling folders, one possible fix is to run 'npm link ../myapp/node_modules/react' from 'mylib'. This should make the library use the application’s React copy.

Thus, running the command: npm link ../../libraries/core/decipher/node_modules/react from my project folder has fixed the issue.

You may need to config the CORS at Spring Boot side. Please add below class in your Project.

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
@EnableWebMvc
public class WebConfig implements Filter,WebMvcConfigurer {



    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**");
    }

    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) {
      HttpServletResponse response = (HttpServletResponse) res;
      HttpServletRequest request = (HttpServletRequest) req;
      System.out.println("WebConfig; "+request.getRequestURI());
      response.setHeader("Access-Control-Allow-Origin", "*");
      response.setHeader("Access-Control-Allow-Methods", "POST, PUT, GET, OPTIONS, DELETE");

              chain.doFilter(req, res);
          } catch(Exception e) {
              e.printStackTrace();

          "USERID"+"ROLE"+
                  "access-control-request-headers,access-control-request-method,accept,origin,authorization,x-requested-with,responseType,observe");
          response.setStatus(HttpServletResponse.SC_OK);
      }

    }

}

UPDATE:

To append Token to each request you can create one Interceptor as below.

import { Injectable } from '@angular/core';
import { HttpEvent, HttpHandler, HttpInterceptor, HttpRequest } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable()
export class AuthInterceptor implements HttpInterceptor {

  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    const token = window.localStorage.getItem('tokenKey'); // you probably want to store it in localStorage or something


    if (!token) {
      return next.handle(req);
    }

    const req1 = req.clone({
      headers: req.headers.set('Authorization', `${token}`),
    });

    return next.handle(req1);
  }

}

Example

useStyles is a React hook which are meant to be used in functional components and can not be used in class components.

From React:

Hooks let you use state and other React features without writing a class.

Also you should call useStyles hook inside your function like;

function Welcome() {
  const classes = useStyles();
...

If you want to use hooks, here is your brief class component changed into functional component;

import React from "react";
import { Container, makeStyles } from "@material-ui/core";

const useStyles = makeStyles({
  root: {
    background: "linear-gradient(45deg, #FE6B8B 30%, #FF8E53 90%)",
    border: 0,
    borderRadius: 3,
    boxShadow: "0 3px 5px 2px rgba(255, 105, 135, .3)",
    color: "white",
    height: 48,
    padding: "0 30px"
  }
});

function Welcome() {
  const classes = useStyles();
  return (
    <Container className={classes.root}>
      <h1>Welcome</h1>
    </Container>
  );
}

export default Welcome;

esModuleInterop generates the helpers outlined in the docs. Looking at the generated code, we can see exactly what these do:

//ts 
import React from 'react'
//js 
var __importDefault = (this && this.__importDefault) || function (mod) {
    return (mod && mod.__esModule) ? mod : { "default": mod };
};
Object.defineProperty(exports, "__esModule", { value: true });
var react_1 = __importDefault(require("react"));

__importDefault: If the module is not an es module then what is returned by require becomes the default. This means that if you use default import on a commonjs module, the whole module is actually the default.

__importStar is best described in this PR:

TypeScript treats a namespace import (i.e. import * as foo from "foo") as equivalent to const foo = require("foo"). Things are simple here, but they don't work out if the primary object being imported is a primitive or a value with call/construct signatures. ECMAScript basically says a namespace record is a plain object.

Babel first requires in the module, and checks for a property named __esModule. If __esModule is set to true, then the behavior is the same as that of TypeScript, but otherwise, it synthesizes a namespace record where:

1. All properties are plucked off of the require'd module and made available as named imports.
2. The originally require'd module is made available as a default import.

So we get this:

// ts
import * as React from 'react'

// emitted js
var __importStar = (this && this.__importStar) || function (mod) {
    if (mod && mod.__esModule) return mod;
    var result = {};
    if (mod != null) for (var k in mod) if (Object.hasOwnProperty.call(mod, k)) result[k] = mod[k];
    result["default"] = mod;
    return result;
};
Object.defineProperty(exports, "__esModule", { value: true });
var React = __importStar(require("react"));

allowSyntheticDefaultImports is the companion to all of this, setting this to false will not change the emitted helpers (both of them will still look the same). But it will raise a typescript error if you are using default import for a commonjs module. So this import React from 'react' will raise the error Module '".../node_modules/@types/react/index"' has no default export. if allowSyntheticDefaultImports is false.

Got this error on eclipse IDE version 4.10, Spring boot 2.2.0.M4, changed the Spring boot version to 2.2.0.M2 (after many other solutions recommended and it solved the error). Maybe something missing or broken in the latest version of Spring boot starter project module maven POM.

I'm Daniel Stenberg.

I made curl

I founded the curl project back in 1998, I wrote the initial curl version and I created libcurl. I've written more than half of all the 24,000 commits done in the source code repository up to this point in time. I'm still the lead developer of the project. To a large extent, curl is my baby.

I shipped the first version of curl as open source since I wanted to "give back" to the open source world that had given me so much code already. I had used so much open source and I wanted to be as cool as the other open source authors.

Thanks to it being open source, literally thousands of people have been able to help us out over the years and have improved the products, the documentation. the web site and just about every other detail around the project. curl and libcurl would never have become the products that they are today were they not open source. The list of contributors now surpass 1900 names and currently the list grows with a few hundred names per year.

Thanks to curl and libcurl being open source and liberally licensed, they were immediately adopted in numerous products and soon shipped by operating systems and Linux distributions everywhere thus getting a reach beyond imagination.

Thanks to them being "everywhere", available and liberally licensed they got adopted and used everywhere and by everyone. It created a defacto transfer library standard.

At an estimated six billion installations world wide, we can safely say that curl is the most widely used internet transfer library in the world. It simply would not have gone there had it not been open source. curl runs in billions of mobile phones, a billion Windows 10 installations, in a half a billion games and several hundred million TVs - and more.

Should I have released it with proprietary license instead and charged users for it? It never occured to me, and it wouldn't have worked because I would never had managed to create this kind of stellar project on my own. And projects and companies wouldn't have used it.

Why do I still work on curl?

Now, why do I and my fellow curl developers still continue to develop curl and give it away for free to the world?

1. I can't speak for my fellow project team members. We all participate in this for our own reasons.
2. I think it's still the right thing to do. I'm proud of what we've accomplished and I truly want to make the world a better place and I think curl does its little part in this.
3. There are still bugs to fix and features to add!
4. curl is free but my time is not. I still have a job and someone still has to pay someone for me to get paid every month so that I can put food on the table for my family. I charge customers and companies to help them with curl. You too can get my help for a fee, which then indirectly helps making sure that curl continues to evolve, remain free and the kick-ass product it is.
5. curl was my spare time project for twenty years before I started working with it full time. I've had great jobs and worked on awesome projects. I've been in a position of luxury where I could continue to work on curl on my spare time and keep shipping a quality product for free. My work on curl has given me friends, boosted my career and taken me to places I would not have been at otherwise.
6. I would not do it differently if I could back and do it again.

Am I proud of what we've done?

Yes. So insanely much.

But I'm not satisfied with this and I'm not just leaning back, happy with what we've done. I keep working on curl every single day, to improve, to fix bugs, to add features and to make sure curl keeps being the number one file transfer solution for the world even going forward.

We do mistakes along the way. We make the wrong decisions and sometimes we implement things in crazy ways. But to win in the end and to conquer the world is about patience and endurance and constantly going back and reconsidering previous decisions and correcting previous mistakes. To continuously iterate, polish off rough edges and gradually improve over time.

Never give in. Never stop. Fix bugs. Add features. Iterate. To the end of time.

For real?

Yeah. For real.

Do I ever get tired? Is it ever done?

Sure I get tired at times. Working on something every day for over twenty years isn't a paved downhill road. Sometimes there are obstacles. During times things are rough. Occasionally people are just as ugly and annoying as people can be.

But curl is my life's project and I have patience. I have thick skin and I don't give up easily. The tough times pass and most days are awesome. I get to hang out with awesome people and the reward is knowing that my code helps driving the Internet revolution everywhere is an ego boost above normal.

curl will never be "done" and so far I think work on curl is pretty much the most fun I can imagine. Yes, I still think so even after twenty years in the driver's seat. And as long as I think it's fun I intend to keep at it.

If you want to use tf.contrib, you need to now copy and paste the source code from github into your script/notebook. It's annoying and doesn't always work. But that's the only workaround I've found. For example, if you wanted to use tf.contrib.opt.AdamWOptimizer, you have to copy and paste from here. https://github.com/tensorflow/tensorflow/blob/590d6eef7e91a6a7392c8ffffb7b58f2e0c8bc6b/tensorflow/contrib/opt/python/training/weight_decay_optimizers.py#L32

The solution is simple, correct "app" and write "App" with the first character in uppercase.

The solution is also given by react, they advice you use useCallback which will return a memoize version of your function :

The 'fetchBusinesses' function makes the dependencies of useEffect Hook (at line NN) change on every render. To fix this, wrap the 'fetchBusinesses' definition into its own useCallback() Hook react-hooks/exhaustive-deps

useCallback is simple to use as it has the same signature as useEffect the difference is that useCallback returns a function. It would look like this :

 const fetchBusinesses = useCallback( () => {
        return fetch("theURL", {method: "GET"}
    )
    .then(() => { /* some stuff */ })
    .catch(() => { /* some error handling */ })
  }, [/* deps */])
  // We have a first effect thant uses fetchBusinesses
  useEffect(() => {
    // do things and then fetchBusinesses
    fetchBusinesses(); 
  }, [fetchBusinesses]);
   // We can have many effect thant uses fetchBusinesses
  useEffect(() => {
    // do other things and then fetchBusinesses
    fetchBusinesses();
  }, [fetchBusinesses]);

How about reinstalling the node module? Go to the root directory of the project and remove the current node modules and install again.

These are the commands : rm -rf node_modules npm install

OR

npm uninstall -g react-native-cli and

npm install -g react-native-cli

Try the following commands in terminal, this will work better:

apt-get install curl

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

python get-pip.py

After Migrated to Angular8, core-js/es6 or core-js/es7 Will not work.

You have to simply replace import core-js/es/

For ex.

import 'core-js/es6/symbol'  

to

import 'core-js/es/symbol'

This will work properly.

I also have the same problem, and the solution is I didn't bind the event in my onClick. so when it renders for the first time and the data is more, which ends up calling the state setter again, which triggers React to call your function again and so on.

export default function Component(props) {

function clickEvent (event, variable){
    console.log(variable);
}

return (
    <div>
        <IconButton
            key="close"
            aria-label="Close"
            color="inherit"
            onClick={e => clickEvent(e, 10)} // or you can call like this:onClick={() => clickEvent(10)} 
        >
    </div>
)
}

Travis CI alternative

Another answer since Francesco Borzi's didn't work for me.

Add this to your travis.yml:

addons:
  chrome: stable

before_script:
  - LATEST_CHROMEDRIVER_VERSION=`curl -s "https://chromedriver.storage.googleapis.com/LATEST_RELEASE"`
  - curl "https://chromedriver.storage.googleapis.com/${LATEST_CHROMEDRIVER_VERSION}/chromedriver_linux64.zip" -O
  - unzip chromedriver_linux64.zip -d ~/bin

To install all currently supported python versions (python 3.6 is already pre-installed) including pip for Ubuntu 18.04 do the following:

To install python3.5 and python3.7, use the deadsnakes ppa:

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.5
sudo apt-get install python3.7

Install python2.7 via distribution packages:

sudo apt install python-minimal  # on Ubuntu 18.04 python-minimal maps to python2.7

To install pip use:

sudo apt install python-pip  # on Ubuntu 18.04 this refers to pip for python2.7
sudo apt install python3-pip  # on Ubuntu 18.04 this refers to pip for python3.6
python3.5 -m pip install pip # this will install pip only for the current user
python3.7 -m pip install pip

I used it for setting up a CI-chain for a python project with tox and Jenkins.

There're 3 ways to achieve this after conda 4.6. (The last method has the highest priority.)

1. Use sub-command conda config to change the setting.

   conda config --set auto_activate_base false
   

2. In fact, the former conda config sub-command is changing configuration file .condarc. We can modify .condarc directly. Add following content into .condarc under your home directory,

   # auto_activate_base (bool)
   #   Automatically activate the base environment during shell
   #   initialization. for `conda init`
   auto_activate_base: false
   

3. Set environment variable CONDA_AUTO_ACTIVATE_BASE in the shell's init file. (.bashrc for bash, .zshrc for zsh)

   CONDA_AUTO_ACTIVATE_BASE=false
   

   To convert from the condarc file-based configuration parameter name to the environment variable parameter name, make the name all uppercase and prepend CONDA_. For example, conda’s always_yes configuration parameter can be specified using a CONDA_ALWAYS_YES environment variable.

   The environment settings take precedence over corresponding settings in .condarc file.

Just add this at start: image = cv2.imread(image)

I leave you a utility function to inmutably update objects

/**
 * Inmutable update object
 * @param  {Object} oldObject     Object to update
 * @param  {Object} updatedValues Object with new values
 * @return {Object}               New Object with updated values
 */
export const updateObject = (oldObject, updatedValues) => {
  return {
    ...oldObject,
    ...updatedValues
  };
};

So you can use it like this

const MyComponent = props => {

  const [orderForm, setOrderForm] = useState({
    specialities: {
      elementType: "select",
      elementConfig: {
        options: [],
        label: "Specialities"
      },
      touched: false
    }
  });


// I want to update the options list, to fill a select element

  // ---------- Update with fetched elements ---------- //

  const updateSpecialitiesData = data => {
    // Inmutably update elementConfig object. i.e label field is not modified
    const updatedOptions = updateObject(
      orderForm[formElementKey]["elementConfig"],
      {
        options: data
      }
    );
    // Inmutably update the relevant element.
    const updatedFormElement = updateObject(orderForm[formElementKey], {
      touched: true,
      elementConfig: updatedOptions
    });
    // Inmutably update the relevant element in the state.
    const orderFormUpdated = updateObject(orderForm, {
      [formElementKey]: updatedFormElement
    });
    setOrderForm(orderFormUpdated);
  };

  useEffect(() => {
      // some code to fetch data
      updateSpecialitiesData.current("specialities",fetchedData);
  }, [updateSpecialitiesData]);

// More component code
}

If not you have more utilities here : https://es.reactjs.org/docs/update.html

this issue was driving me insane until i found this post which said to do

brew upgrade python3 

(not using pycharm, using sublime)

Error when importing ssl in Python 3.7.4 on macOS 10.14.6

For future purposes, this may help too:

It's ok to use setState in useEffect you just need to have attention as described already to not create a loop.

But it's not the only problem that may occur. See below:

Imagine that you have a component Comp that receives props from parent and according to a props change you want to set Comp's state. For some reason, you need to change for each prop in a different useEffect:

DO NOT DO THIS

useEffect(() => {
  setState({ ...state, a: props.a });
}, [props.a]);

useEffect(() => {
  setState({ ...state, b: props.b });
}, [props.b]);

It may never change the state of a as you can see in this example: https://codesandbox.io/s/confident-lederberg-dtx7w

The reason why this happen in this example it's because both useEffects run in the same react cycle when you change both prop.a and prop.b so the value of {...state} when you do setState are exactly the same in both useEffect because they are in the same context. When you run the second setState it will replace the first setState.

DO THIS INSTEAD

The solution for this problem is basically call setState like this:

useEffect(() => {
  setState(state => ({ ...state, a: props.a }));
}, [props.a]);

useEffect(() => {
  setState(state => ({ ...state, b: props.b }));
}, [props.b]);

Check the solution here: https://codesandbox.io/s/mutable-surf-nynlx

Now, you always receive the most updated and correct value of the state when you proceed with the setState.

I hope this helps someone!

I upgraded my IntelliJ Version from 2018.1 to 2018.3.6. It works !

Don't struggle to add the path to each image asset, instead just specify the path to your images directory.
just make sure you use proper indentations as the pubspec.yaml is indent sensitive.

flutter:

  uses-material-design: true
  assets:
    - images/

and you can simply access each image as

  new Image.asset('images/pizza1.png',width:300,height:100)

In the root open the .editorconfig file and change:

end_of_line = lf

to

end_of_line = auto

This should fix it for new files.

(Editor's note: this answer is contradicted by evidence from looking at the asm, as shown by another answer. This was a guess backed up by some experiments, but it turned out not to be correct.)

When the multiplication is 2 * (i * i), the JVM is able to factor out the multiplication by 2 from the loop, resulting in this equivalent but more efficient code:

int n = 0;
for (int i = 0; i < 1000000000; i++) {
    n += i * i;
}
n *= 2;

but when the multiplication is (2 * i) * i, the JVM doesn't optimize it since the multiplication by a constant is no longer right before the n += addition.

Here are a few reasons why I think this is the case:

• Adding an if (n == 0) n = 1 statement at the start of the loop results in both versions being as efficient, since factoring out the multiplication no longer guarantees that the result will be the same
• The optimized version (by factoring out the multiplication by 2) is exactly as fast as the 2 * (i * i) version

Here is the test code that I used to draw these conclusions:

public static void main(String[] args) {
    long fastVersion = 0;
    long slowVersion = 0;
    long optimizedVersion = 0;
    long modifiedFastVersion = 0;
    long modifiedSlowVersion = 0;

    for (int i = 0; i < 10; i++) {
        fastVersion += fastVersion();
        slowVersion += slowVersion();
        optimizedVersion += optimizedVersion();
        modifiedFastVersion += modifiedFastVersion();
        modifiedSlowVersion += modifiedSlowVersion();
    }

    System.out.println("Fast version: " + (double) fastVersion / 1000000000 + " s");
    System.out.println("Slow version: " + (double) slowVersion / 1000000000 + " s");
    System.out.println("Optimized version: " + (double) optimizedVersion / 1000000000 + " s");
    System.out.println("Modified fast version: " + (double) modifiedFastVersion / 1000000000 + " s");
    System.out.println("Modified slow version: " + (double) modifiedSlowVersion / 1000000000 + " s");
}

private static long fastVersion() {
    long startTime = System.nanoTime();
    int n = 0;
    for (int i = 0; i < 1000000000; i++) {
        n += 2 * (i * i);
    }
    return System.nanoTime() - startTime;
}

private static long slowVersion() {
    long startTime = System.nanoTime();
    int n = 0;
    for (int i = 0; i < 1000000000; i++) {
        n += 2 * i * i;
    }
    return System.nanoTime() - startTime;
}

private static long optimizedVersion() {
    long startTime = System.nanoTime();
    int n = 0;
    for (int i = 0; i < 1000000000; i++) {
        n += i * i;
    }
    n *= 2;
    return System.nanoTime() - startTime;
}

private static long modifiedFastVersion() {
    long startTime = System.nanoTime();
    int n = 0;
    for (int i = 0; i < 1000000000; i++) {
        if (n == 0) n = 1;
        n += 2 * (i * i);
    }
    return System.nanoTime() - startTime;
}

private static long modifiedSlowVersion() {
    long startTime = System.nanoTime();
    int n = 0;
    for (int i = 0; i < 1000000000; i++) {
        if (n == 0) n = 1;
        n += 2 * i * i;
    }
    return System.nanoTime() - startTime;
}

And here are the results:

Fast version: 5.7274411 s
Slow version: 7.6190804 s
Optimized version: 5.1348007 s
Modified fast version: 7.1492705 s
Modified slow version: 7.2952668 s

Had the same Issue when i decided to install another version of Android Studio, what worked for me was:

• Creating a new project with the current version of Android Studio just to go check the classpath version at the project level build.gradle inside the dependencies section, at the time it was this:

classpath 'com.android.tools.build:gradle:3.5.0-rc01'

Copied that line and replaced it on the project i was working on.

Error :

issue : while installing opencv python via

pip3 install opencv-python

  Problem with the CMake installation, aborting build. CMake executable is cmake
  
  ----------------------------------------
  Failed building wheel for opencv-python
  Running setup.py clean for opencv-python

What worked for me

pip3 install --upgrade pip setuptools wheel

After this you still might received fallowing error error

    from .cv2 import *
ImportError: libGL.so.1: cannot open shared object file: No such file or directory

Installing libgl solved the error for me.

sudo apt update
sudo apt install libgl1-mesa-glx

Hope this helps

Reason for the error:

Column tries to expands in vertical axis, and so does the ListView, hence you need to constrain the height of ListView.

Solutions

1. Use either Expanded or Flexible if you want to allow ListView to take up entire left space in Column.

   Column(
     children: <Widget>[
       Expanded(
         child: ListView(...),
       )
     ],
   )
   

2. Use SizedBox if you want to restrict the size of ListView to a certain height.

   Column(
     children: <Widget>[
       SizedBox(
         height: 200, // constrain height
         child: ListView(),
       )
     ],
   )
   

3. Use shrinkWrap, if your ListView isn't too big.

   Column(
     children: <Widget>[
       ListView(
         shrinkWrap: true, // use it
       )
     ],
   )
   

This error happened because the image didn't load properly . So you have problem with the previous line cv2.imread my suggestion is :

• check if the images exist in the path you give

• check the count variable if he have valid number

Normally when an optimization algorithm does not converge, it is usually because the problem is not well-conditioned, perhaps due to a poor scaling of the decision variables. There are a few things you can try.

1. Normalize your training data so that the problem hopefully becomes more well conditioned, which in turn can speed up convergence. One possibility is to scale your data to 0 mean, unit standard deviation using Scikit-Learn's StandardScaler for an example. Note that you have to apply the StandardScaler fitted on the training data to the test data.
2. Related to 1), make sure the other arguments such as regularization weight, C, is set appropriately.
3. Set max_iter to a larger value. The default is 1000.
4. Set dual = True if number of features > number of examples and vice versa. This solves the SVM optimization problem using the dual formulation. Thanks @Nino van Hooff for pointing this out, and @JamesKo for spotting my mistake.
5. Use a different solver, for e.g., the L-BFGS solver if you are using Logistic Regression. See @5ervant's answer.

Note: One should not ignore this warning.

This warning came about because

1. Solving the linear SVM is just solving a quadratic optimization problem. The solver is typically an iterative algorithm that keeps a running estimate of the solution (i.e., the weight and bias for the SVM). It stops running when the solution corresponds to an objective value that is optimal for this convex optimization problem, or when it hits the maximum number of iterations set.

2. If the algorithm does not converge, then the current estimate of the SVM's parameters are not guaranteed to be any good, hence the predictions can also be complete garbage.

Edit

In addition, consider the comment by @Nino van Hooff and @5ervant to use the dual formulation of the SVM. This is especially important if the number of features you have, D, is more than the number of training examples N. This is what the dual formulation of the SVM is particular designed for and helps with the conditioning of the optimization problem. Credit to @5ervant for noticing and pointing this out.

Furthermore, @5ervant also pointed out the possibility of changing the solver, in particular the use of the L-BFGS solver. Credit to him (i.e., upvote his answer, not mine).

I would like to provide a quick rough explanation for those who are interested (I am :)) why this matters in this case. Second-order methods, and in particular approximate second-order method like the L-BFGS solver, will help with ill-conditioned problems because it is approximating the Hessian at each iteration and using it to scale the gradient direction. This allows it to get better convergence rate but possibly at a higher compute cost per iteration. That is, it takes fewer iterations to finish but each iteration will be slower than a typical first-order method like gradient-descent or its variants.

For e.g., a typical first-order method might update the solution at each iteration like

x(k + 1) = x(k) - alpha(k) * gradient(f(x(k)))

where alpha(k), the step size at iteration k, depends on the particular choice of algorithm or learning rate schedule.

A second order method, for e.g., Newton, will have an update equation

x(k + 1) = x(k) - alpha(k) * Hessian(x(k))^(-1) * gradient(f(x(k)))

That is, it uses the information of the local curvature encoded in the Hessian to scale the gradient accordingly. If the problem is ill-conditioned, the gradient will be pointing in less than ideal directions and the inverse Hessian scaling will help correct this.

In particular, L-BFGS mentioned in @5ervant's answer is a way to approximate the inverse of the Hessian as computing it can be an expensive operation.

However, second-order methods might converge much faster (i.e., requires fewer iterations) than first-order methods like the usual gradient-descent based solvers, which as you guys know by now sometimes fail to even converge. This can compensate for the time spent at each iteration.

In summary, if you have a well-conditioned problem, or if you can make it well-conditioned through other means such as using regularization and/or feature scaling and/or making sure you have more examples than features, you probably don't have to use a second-order method. But these days with many models optimizing non-convex problems (e.g., those in DL models), second order methods such as L-BFGS methods plays a different role there and there are evidence to suggest they can sometimes find better solutions compared to first-order methods. But that is another story.

With Homebrew and jenv:

Assumption: Mac machine and you already have installed homebrew.

Install cask:

$ brew tap caskroom/cask
$ brew tap caskroom/versions

To install latest java:

$ brew cask install java

To install java 8:

$ brew cask install java8

To install java 9:

$ brew cask install java9

If you want to install/manage multiple version then you can use 'jenv':

Install and configure jenv:

$ brew install jenv
$ echo 'export PATH="$HOME/.jenv/bin:$PATH"' >> ~/.bash_profile
$ echo 'eval "$(jenv init -)"' >> ~/.bash_profile
$ source ~/.bash_profile

Add the installed java to jenv:

$ jenv add /Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home
$ jenv add /Library/Java/JavaVirtualMachines/jdk1.11.0_2.jdk/Contents/Home

To see all the installed java:

$ jenv versions

Above command will give the list of installed java:

* system (set by /Users/lyncean/.jenv/version)
1.8
1.8.0.202-ea
oracle64-1.8.0.202-ea

Configure the java version which you want to use:

$ jenv global oracle64-1.6.0.39

For me what worked is the following:

sudo xcode-select --reset

Then like in @High6's answer:

sudo xcodebuild -license

This will reveal a license which I assume is some Xcode license. Scroll to the bottom using space (or the mouse) then tap agree.

This is what worked for me on MacOS Mojave v 10.14.

You can use Amazon Corretto. It is free to use multiplatform, production-ready distribution of the OpenJDK. It comes with long-term support that will include performance enhancements and security fixes. Check the installation instructions here.

You can also check Zulu from Azul.

One more thing I like to highlight here is both Amazon Corretto and Zulu are TCK Compliant. You can see the OpenJDK builds comparison here and here.

Now it is possible to install openjdk-11 this way:

sudo apt-get install openjdk-11-jdk

(Previously it installed openjdk-10, but not anymore)

Change your Google Services version from your build.gradle:

dependencies {
  classpath 'com.google.gms:google-services:4.2.0'
}

None of the above worked for me. I spent too much time clearing other errors that came up. I found this to be the easiest and the best way.

This works for getting JavaFx on Jdk 11, 12 & on OpenJdk12 too!

• The Video shows you the JavaFx Sdk download
• How to set it as a Global Library
• Set the module-info.java (i prefer the bottom one)

module thisIsTheNameOfYourProject {
    requires javafx.fxml;
    requires javafx.controls;
    requires javafx.graphics;
    opens sample;
}

The entire thing took me only 5mins !!!

In short:

• OpenJDK has multiple meanings and can refer to:
  • free and open source implementation of the Java Platform, Standard Edition (Java SE)
  • open source repository — the Java source code aka OpenJDK project
  • prebuilt OpenJDK binaries maintained by Oracle
  • prebuilt OpenJDK binaries maintained by the OpenJDK community
• AdoptOpenJDK — prebuilt OpenJDK binaries maintained by community (open source licensed)

Explanation:

Prebuilt OpenJDK (or distribution) — binaries, built from http://hg.openjdk.java.net/, provided as an archive or installer, offered for various platforms, with a possible support contract.

OpenJDK, the source repository (also called OpenJDK project) - is a Mercurial-based open source repository, hosted at http://hg.openjdk.java.net. The Java source code. The vast majority of Java features (from the VM and the core libraries to the compiler) are based solely on this source repository. Oracle have an alternate fork of this.

OpenJDK, the distribution (see the list of providers below) - is free as in beer and kind of free as in speech, but, you do not get to call Oracle if you have problems with it. There is no support contract. Furthermore, Oracle will only release updates to any OpenJDK (the distribution) version if that release is the most recent Java release, including LTS (long-term support) releases. The day Oracle releases OpenJDK (the distribution) version 12.0, even if there's a security issue with OpenJDK (the distribution) version 11.0, Oracle will not release an update for 11.0. Maintained solely by Oracle.

Some OpenJDK projects - such as OpenJDK 8 and OpenJDK 11 - are maintained by the OpenJDK community and provide releases for some OpenJDK versions for some platforms. The community members have taken responsibility for releasing fixes for security vulnerabilities in these OpenJDK versions.

AdoptOpenJDK, the distribution is very similar to Oracle's OpenJDK distribution (in that it is free, and it is a build produced by compiling the sources from the OpenJDK source repository). AdoptOpenJDK as an entity will not be backporting patches, i.e. there won't be an AdoptOpenJDK 'fork/version' that is materially different from upstream (except for some build script patches for things like Win32 support). Meaning, if members of the community (Oracle or others, but not AdoptOpenJDK as an entity) backport security fixes to updates of OpenJDK LTS versions, then AdoptOpenJDK will provide builds for those. Maintained by OpenJDK community.

OracleJDK - is yet another distribution. Starting with JDK12 there will be no free version of OracleJDK. Oracle's JDK distribution offering is intended for commercial support. You pay for this, but then you get to rely on Oracle for support. Unlike Oracle's OpenJDK offering, OracleJDK comes with longer support for LTS versions. As a developer you can get a free license for personal/development use only of this particular JDK, but that's mostly a red herring, as 'just the binary' is basically the same as the OpenJDK binary. I guess it means you can download security-patched versions of LTS JDKs from Oracle's websites as long as you promise not to use them commercially.

Note. It may be best to call the OpenJDK builds by Oracle the "Oracle OpenJDK builds".

Donald Smith, Java product manager at Oracle writes:

Ideally, we would simply refer to all Oracle JDK builds as the "Oracle JDK", either under the GPL or the commercial license, depending on your situation. However, for historical reasons, while the small remaining differences exist, we will refer to them separately as Oracle’s OpenJDK builds and the Oracle JDK.

_{Free Builds from Source - the distribution source code is publicly available and one can assemble its own build}

_{Free Binary Distributions - the distribution binaries are publicly available for download and usage}

_{Extended Updates - aka LTS (long-term support) - Public Updates beyond the 6-month release lifecycle}

_{Commercial Support - some providers offer extended updates and customer support to paying customers, e.g. Oracle JDK (support details)}

_{Permissive License - the distribution license is non-protective, e.g. Apache 2.0}

Which Java Distribution Should I Use?

In the Sun/Oracle days, it was usually Sun/Oracle producing the proprietary downstream JDK distributions based on OpenJDK sources. Recently, Oracle had decided to do their own proprietary builds only with the commercial support attached. They graciously publish the OpenJDK builds as well on their https://jdk.java.net/ site.

What is happening starting JDK 11 is the shift from single-vendor (Oracle) mindset to the mindset where you select a provider that gives you a distribution for the product, under the conditions you like: platforms they build for, frequency and promptness of releases, how support is structured, etc. If you don't trust any of existing vendors, you can even build OpenJDK yourself.

Each build of OpenJDK is usually made from the same original upstream source repository (OpenJDK “the project”). However each build is quite unique - $free or commercial, branded or unbranded, pure or bundled (e.g., BellSoft Liberica JDK offers bundled JavaFX, which was removed from Oracle builds starting JDK 11).

If no environment (e.g., Linux) and/or license requirement defines specific distribution and if you want the most standard JDK build, then probably the best option is to use OpenJDK by Oracle or AdoptOpenJDK.

There is no wheel (prebuilt package) for Python 3.7 on Windows (there is one for Python 2.7 and 3.4 up to 3.6) so you need to prepare build environment on your PC to use this package. Easier would be finding the wheel for 3.7 as some packages are quite hard to build on Windows.

Christoph Gohlke (University of California) hosts Windows wheels for most popular packages for nearly all modern Python versions, including latest PyAudio. You can find it here: https://www.lfd.uci.edu/~gohlke/pythonlibs/ (download can be quite slow). After download, just type pip install <downloaded file here>.

There is no difference between python -m pip install, and pip install as long as you're using default installation settings and single python installation. python pip actually tries to run file pip in the current directory.

Edit. See the pipwin comment for automated way of using Mr Goblke's libs . Note that I've not used it myself and I'm not sure about selecting different package flavors like vanilla and mkl versions of numpy.

Download version tar.gz for windows and just extract files to the folder by your needs. On the left pane, you can select which version of openjdk to download

Tutorial: unzip as expected. You need to set system variable PATH to include your directory with openjdk so you can type java -version in console.

JDK vs OpenJDK

<a [routerLink]="" (click)="openSite(SiteUrl)">{{SiteUrl}}</a>

and in your Component.ts

openSite(siteUrl) {
   window.open("//" + siteUrl, '_blank');
}

I just tested on Laravel Framework 5.7.19 and the following steps work:

Make sure your .babelrc file is in the root folder of your application, and add the following code:

{
  "plugins": ["@babel/plugin-proposal-class-properties"]
}

Run npm install --save-dev @babel/plugin-proposal-class-properties.

Run npm run watch.

Comment This Line in gradle.properties

android.useAndroidX=true

Oh my. There are so many bad answers here. Well meaning but misleading. I am usually fine with dealing with permissions on Mac/Linux. Windows is new to me these days. This is the problem I had.

1. Create a virtualenv - ok
2. activate my virtualenv - failed. Needs Scope to run powershell. Windows is helpful and tell you exactly the command you need to run to allow .ps to run. Sort of like chmod but with execution scope which I think is good.
3. Now if you are past the above and install a few packages then it's fine. Until you suddenly cant. Then you get this permission error.
4. Something you or another process did set the permission on the folder where pip installs packages. i.e. ...site-packages/ In my case I suspect it's OneDrive or some permission inheritence.

The ideal way forward is to check permissions. This is hard but you are a Python developer are you not! First check your own user.

5. whoami e.g. mycomputer\vangel
6. Get-Acl <path which is an issue>
7. on the Python install folder or your virtualenv right click and go to Security Tab. Click advanced and review permissions. I removed all inherited permissions and other users etc and added my whoami user explicity with full permissions. then applied to all objects.

Dont do these without verifying the below steps. Read the message carefully.

By no means it is the solution for all permissions issues that may affect you. I can only provide guidance on how to troubleshoot and hopefully you resolve.

setting --user flag is not necessary anywhere, if it works good for you. But you still do not know what went wrong.

More steps: Try removing a package and installing it. pip uninstall requests pip install requests This works, yet I get permission issue for a specific package.

Turns out, Windows gives permission error when the file is locked by a process. Python reports it as [Winerror 5] and I could not easily find that documentation reference anyway. lets test this theory.

I find the exact file that gets permission error. Hit delete. Sure enough Windows window prompt that its open in python Of course it is.

I hit end task on all python It has worked since 1996. But I waited a few seconds just in case some process is launching python. Checked Task manager all good.

Having failed 20 times in getting pip to install the specific azureml package I was feeling pretty sure this resolved it.

I ran my pip install and it installed perfectly fine.

Moral of the story: Understand what you are doing before copy pasting from Stackoverflow. All the best.

p.s. Please stop installing Python or its packages as administrator. We are past that since 2006

1. Open terminal
2. Run the following command pip install --trusted-host=pypi.org --trusted-host=files.pythonhosted.org opencv-python.
3. Hope it will work.

In my case, this is working perfectly.. I have added below two line codes inside manifest file

tools:replace="android:appComponentFactory"
android:appComponentFactory="whateverString"

Credit goes to this answer.

in my case I had to change line ending from CRLF to LF for the run.sh file and the error was gone.

I hope this helps,
Kirsten

This worked for me:

File >> Project Structure >> Modules >> Dependency >> + (on left-side of window)

clicking the "+" sign will let you designate the directory where you have unpacked JavaFX's "lib" folder.

Scope is Compile (which is the default.) You can then edit this to call it JavaFX by double-clicking on the line.

then in:

Run >> Edit Configurations

Add this line to VM Options:

--module-path /path/to/JavaFX/lib --add-modules=javafx.controls

(oh and don't forget to set the SDK)

I opened XCode -> Preferences -> Accounts and clicked on Download certificate. That fixed my problem

It simply means you have downloaded a spring starter code with database dependency without configuring your database, So it doesn't know how to connect. For Spring boot version 2.18 do the following steps to fix it.

1. Create a database for the driver you have downloaded ie mysql/mongo etc.

2. In your applications.properties file add the db connection info. Sample is given for mysql if your db is mongo change it for mongo.

spring.datasource.url=jdbc:mysql://localhost:3306/db_name_that_you_created
spring.datasource.username=your_db_username_here
spring.datasource.password=your_db_pass_here
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.database-platform = org.hibernate.dialect.MySQL5Dialect
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto = update

3. Reboot the server it will be running.

Question still relevant as of Android Studio 3.5.2 for Windows.

In my specific use case, I was trying to add Gander (https://github.com/Ashok-Varma/Gander) to my list of dependencies when I keep getting this particular headache.

It turns out that I have yet to get JCenter Certificate approved in my cacerts file. I'm going through a company firewall and i had to do this with dependencies that I attempt to import. Thus, to do so:

1. Ensure that your Android Studio does not need to go through any proxy.

2. Export the certificate where you get your dependency (usually just JCenter)

3. Add the certificate to your cacerts file:

   keytool -import -alias [your-certificate-name] -keystore 'C:\Program Files\Java\jdk[version]\jre\lib\security\cacerts' -file [absolute\path\to\your\certificate].cer

4. Restart Android Studio

5. Try syncing again.

Answer is based on this one: https://stackoverflow.com/a/26183328/4972380

It's not good to keep changing the gulp & npm versions in-order to fix the errors. I was getting several exceptions last days after reinstall my working machine. And wasted tons of minutes to re-install & fixing those.

So, I decided to upgrade all to latest versions:

npm -v : v12.13.0 
node -v : 6.13.0
gulp -v : CLI version: 2.2.0 Local version: 4.0.2

This error is getting because of the how it has coded in you gulpfile but not the version mismatch. So, Here you have to change 2 things in the gulpfile to aligned with Gulp version 4. Gulp 4 has changed how initiate the task than Version 3.

1. In version 4, you have to defined the task as a function, before call it as a gulp task by it's string name. In V3:

gulp.task('serve', ['sass'], function() {..});

But in V4 it should be like:

function serve() {
...
}
gulp.task('serve', gulp.series(sass));

2. As @Arthur has mentioned, you need to change the way of passing arguments to the task function. It was like this in V3:

gulp.task('serve', ['sass'], function() { ... });

But in V4, it should be:

gulp.task('serve', gulp.series(sass));

I solved this problem by changing my application package name according to signature certificate details. At first I created application with com.foo.xyz but my certificate organization was 'bar'. So I change my package name to com.bar.xyz and now there is no google play protect warning!

I had the same issue on Windows. I tried to update the environment variables for the path of tesseract which did not work.

What worked for me was to modify the pytesseract.py which can be found at the path C:\Program Files\Python37\Lib\site-packages\pytesseract or usually in the C:\Users\YOUR USER\APPDATA\Python

I changed one line as per below:

#tesseract_cmd = 'tesseract' 
#tesseract_cmd = 'C:\Program Files\Tesseract-OCR\\tesseract.exe'

Note I had to put an extra \ before tesseract as Python was interpreting same as \t and you will get the below error message:

pytesseract.pytesseract.TesseractNotFoundError: C:\Program Files\Tesseract-OCR esseract.exe is not installed or it's not in your path

The problem is in your pubspec.yaml, here you need to delete the last comma.

uses-material-design: true,

Because the bootstrap-select is a bootstrap component and therefore you need to include it in your code as you did for your V3

NOTE: this component only works in boostrap-4 since version 1.13.0

$('select').selectpicker();

To get rid of error:

Use

responseType: 'text' as 'json'

import { HttpClient, HttpHeaders } from '@angular/common/http';
.....
 return this.http
        .post<string>(
            this.baseUrl + '/Tickets/getTicket',
            JSON.stringify(value),
        { headers, responseType: 'text' as 'json' }
        )
        .map(res => {
            return res;
        })
        .catch(this.handleError);

First of all, you should look gradle.properties and these values have to be true. If you cannot see them you have to write.

android.useAndroidX=true
android.enableJetifier=true

After that you can use AndroidX dependencies in your build.gradle (Module: app). Also, you have to check compileSDKVersion and targetVersion. They should be minimum 28. For example I am using 29.

So, an androidx dependency example:

implementation 'androidx.cardview:cardview:1.0.0'

However be careful because everything is not start with androidx like cardview dependency. For example, old design dependency is:

implementation 'com.android.support:design:27.1.1'

But new design dependency is:

implementation 'com.google.android.material:material:1.3.0'

RecyclerView is:

implementation 'androidx.recyclerview:recyclerview:1.1.0'

So, you have to search and read carefully. Happy code.

@canerkaseler

This is how I did it in React:

import MyPDF from '../path/to/file.pdf';
<a href={myPDF} download="My_File.pdf"> Download Here </a>

It's important to override the default file name with download="name_of_file_you_want.pdf" or else the file will get a hash number attached to it when you download.

Thumb rule

A common cause for Chrome to crash during startup is running Chrome as root user (administrator) on Linux. While it is possible to work around this issue by passing --no-sandbox flag when creating your WebDriver session, such a configuration is unsupported and highly discouraged. You need to configure your environment to run Chrome as a regular user instead.

This error message...

org.openqa.selenium.WebDriverException: unknown error: DevToolsActivePort file doesn't exist 

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

Your code trials and the versioning information of all the binaries would have given us some hint about what's going wrong.

However as per Add --disable-dev-shm-usage to default launch flags seems adding the argument --disable-dev-shm-usage will temporary solve the issue.

If you desire to initiate/span a new Chrome Browser session you can use the following solution:

System.setProperty("webdriver.chrome.driver", "C:\\path\\to\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("start-maximized"); // open Browser in maximized mode
options.addArguments("disable-infobars"); // disabling infobars
options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-gpu"); // applicable to windows os only
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("--no-sandbox"); // Bypass OS security model
WebDriver driver = new ChromeDriver(options);
driver.get("https://google.com");

disable-dev-shm-usage

As per base_switches.cc disable-dev-shm-usage seems to be valid only on Linux OS:

#if defined(OS_LINUX) && !defined(OS_CHROMEOS)
// The /dev/shm partition is too small in certain VM environments, causing
// Chrome to fail or crash (see http://crbug.com/715363). Use this flag to
// work-around this issue (a temporary directory will always be used to create
// anonymous shared memory files).
const char kDisableDevShmUsage[] = "disable-dev-shm-usage";
#endif

In the discussion Add an option to use /tmp instead of /dev/shm David mentions:

I think it would depend on how are /dev/shm and /tmp mounted. If they are both mounted as tmpfs I'm assuming there won't be any difference. if for some reason /tmp is not mapped as tmpfs (and I think is mapped as tmpfs by default by systemd), chrome shared memory management always maps files into memory when creating an anonymous shared files, so even in that case shouldn't be much difference. I guess you could force telemetry tests with the flag enabled and see how it goes.

As for why not use by default, it was a pushed back by the shared memory team, I guess it makes sense it should be useing /dev/shm for shared memory by default.

Ultimately all this should be moving to use memfd_create, but I don't think that's going to happen any time soon, since it will require refactoring Chrome memory management significantly.

Reference

You can find a couple of detailed discussions in:

• unknown error: DevToolsActivePort file doesn't exist error while executing Selenium UI test cases on ubuntu
• Tests fail immediately with unknown error: DevToolsActivePort file doesn't exist when running Selenium grid through systemd

sudo npm install -g @angular/cli

use this. it worked for me

I also wanted to create OPEN SSL for Windows 10. An easy way of getting it done without running into a risk of installing unknown software from 3rd party websites and risking entries of viruses, is by using the openssl.exe that comes inside your Git for Windows installation. In my case, I found the open SSL in the following location of Git for Windows Installation.

C:\Program Files\Git\usr\bin\openssl.exe

If you also want instructions on how to use OPENSSL to generate and use Certificates. Here is a write-up on my blog. The step by step instructions first explains how to use Microsoft Windows Default Tool and also OPEN SSL and explains the difference between them.

Since May 23, 2018 update, when you're using a firebase dependency, you must include the firebase-core dependency, too.

If adding it, you still having the error, try to update the gradle plugin in your gradle-wrapper.properties to 4.5 version:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.5-all.zip

and resync the project.

In my case using latest versions of following dependencies solved my issue:

'com.google.android.gms:play-services-analytics:16.0.1'
'com.google.android.gms:play-services-tagmanager:16.0.1'

tl;dr:

concat and append currently sort the non-concatenation index (e.g. columns if you're adding rows) if the columns don't match. In pandas 0.23 this started generating a warning; pass the parameter sort=True to silence it. In the future the default will change to not sort, so it's best to specify either sort=True or False now, or better yet ensure that your non-concatenation indices match.

The warning is new in pandas 0.23.0:

In a future version of pandas pandas.concat() and DataFrame.append() will no longer sort the non-concatenation axis when it is not already aligned. The current behavior is the same as the previous (sorting), but now a warning is issued when sort is not specified and the non-concatenation axis is not aligned, link.

More information from linked very old github issue, comment by smcinerney :

When concat'ing DataFrames, the column names get alphanumerically sorted if there are any differences between them. If they're identical across DataFrames, they don't get sorted.

This sort is undocumented and unwanted. Certainly the default behavior should be no-sort.

After some time the parameter sort was implemented in pandas.concat and DataFrame.append:

sort : boolean, default None

Sort non-concatenation axis if it is not already aligned when join is 'outer'. The current default of sorting is deprecated and will change to not-sorting in a future version of pandas.

Explicitly pass sort=True to silence the warning and sort. Explicitly pass sort=False to silence the warning and not sort.

This has no effect when join='inner', which already preserves the order of the non-concatenation axis.

So if both DataFrames have the same columns in the same order, there is no warning and no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['a', 'b'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['b', 'a'])

print (pd.concat([df1, df2]))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

But if the DataFrames have different columns, or the same columns in a different order, pandas returns a warning if no parameter sort is explicitly set (sort=None is the default value):

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))

FutureWarning: Sorting because non-concatenation axis is not aligned.

   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=True))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=False))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

If the DataFrames have different columns, but the first columns are aligned - they will be correctly assigned to each other (columns a and b from df1 with a and b from df2 in the example below) because they exist in both. For other columns that exist in one but not both DataFrames, missing values are created.

Lastly, if you pass sort=True, columns are sorted alphanumerically. If sort=False and the second DafaFrame has columns that are not in the first, they are appended to the end with no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8], 'e':[5, 0]}, 
                    columns=['b', 'a','e'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3], 'c':[2, 8], 'd':[7, 0]}, 
                    columns=['c','b','a','d'])

print (pd.concat([df1, df2]))

Installing the aab directly from the device, I couldn't find a way for that.

But there is a way to install it through your command line using the following documentation You can install apk to a device through BundleTool

According to "@Albert Vila Calvo" comment he noted that to install bundletools using HomeBrew use brew install bundletool

You can now install extract apks from aab file and install it to a device

Extracting apk files from through the next command

java -jar bundletool-all-0.3.3.jar build-apks --bundle=bundle.aab --output=app.apks --ks=my-release-key.keystore --ks-key-alias=alias --ks-pass=pass:password

Arguments:

• --bundle -> Android Bundle .aab file
• --output -> Destination and file name for the generated apk file
• --ks -> Keystore file used to generate the Android Bundle
• --ks-key-alias -> Alias for keystore file
• --ks-pass -> Password for Alias file (Please note the 'pass' prefix before password value)

Then you will have a file with extension .apks So now you need to install it to a device

java -jar bundletool-all-0.6.0.jar install-apks --adb=/android-sdk/platform-tools/adb --apks=app.apks

Arguments:

• --adb -> Path to adb file
• --apks -> Apks file need to be installed

I had the same problem, as it did not installed

@angular-devkit/build-angular

The answer which has worked for me was this:

npm i --only=dev

for angular 6 and above

The working solution for me was

npm install

ng update

and finally

npm update

As simple as this command says npm uninstall your-package-name This command will simply remove package without pain from node modules folder as well as from package.json

For Angular Version 11+

Configuration

The styles and scripts options in your angular.json configuration now allow to reference a package directly:

before: "styles": ["../node_modules/bootstrap/dist/css/bootstrap.css"]
after: "styles": ["bootstrap/dist/css/bootstrap.css"]

          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/ng6",
            "index": "src/index.html",
            "main": "src/main.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "src/tsconfig.app.json",
            "assets": [
              "src/favicon.ico",
              "src/assets"
            ],
            "styles": [
              "src/styles.css","bootstrap/dist/css/bootstrap.min.css"

            ],
            "scripts": [
                       "jquery/dist/jquery.min.js",
                       "bootstrap/dist/js/bootstrap.min.js"
                       ]
          },

Angular Version 10 and below

Angular v6 Onwards

CLI projects in angular 6 onwards will be using angular.json instead of .angular-cli.json for build and project configuration.

Each CLI workspace has projects, each project has targets, and each target can have configurations.Docs

. {
  "projects": {
    "my-project-name": {
      "projectType": "application",
      "architect": {
        "build": {
          "configurations": {
            "production": {},
            "demo": {},
            "staging": {},
          }
        },
        "serve": {},
        "extract-i18n": {},
        "test": {},
      }
    },
    "my-project-name-e2e": {}
  },
}

OPTION-1
execute npm install bootstrap@4 jquery --save
The JavaScript parts of Bootstrap are dependent on jQuery. So you need the jQuery JavaScript library file too.

In your angular.json add the file paths to the styles and scripts array in under build target
NOTE: Before v6 the Angular CLI project configuration was stored in <PATH_TO_PROJECT>/.angular-cli.json. As of v6 the location of the file changed to angular.json. Since there is no longer a leading dot, the file is no longer hidden by default and is on the same level.
which also means that file paths in angular.json should not contain leading dots and slash

i.e you can provide an absolute path instead of a relative path

In .angular-cli.json file Path was "../node_modules/"
In angular.json it is "node_modules/"

 "build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/ng6",
            "index": "src/index.html",
            "main": "src/main.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "src/tsconfig.app.json",
            "assets": [
              "src/favicon.ico",
              "src/assets"
            ],
            "styles": [
              "src/styles.css","node_modules/bootstrap/dist/css/bootstrap.min.css"
               
            ],
            "scripts": ["node_modules/jquery/dist/jquery.min.js",
                       "node_modules/bootstrap/dist/js/bootstrap.min.js"]
          },

OPTION 2
Add files from CDN (Content Delivery Network) to your project CDN LINK

Open file src/index.html and insert

the <link> element at the end of the head section to include the Bootstrap CSS file
a <script> element to include jQuery at the bottom of the body section
a <script> element to include Popper.js at the bottom of the body section
a <script> element to include the Bootstrap JavaScript file at the bottom of the body section

  <!doctype html>
    <html>
    <head>
      <meta charset="utf-8">
      <title>Angular</title>
      <base href="/">
      <meta name="viewport" content="width=device-width, initial-scale=1">
      <link rel="icon" type="image/x-icon" href="favicon.ico">

    </body>
    </html>

OPTION 3
Execute npm install bootstrap
In src/styles.css add the following line:

@import "~bootstrap/dist/css/bootstrap.css";

OPTION-4
ng-bootstrap It contains a set of native Angular directives based on Bootstrap’s markup and CSS. As a result, it's not dependent on jQuery or Bootstrap’s JavaScript

npm install --save @ng-bootstrap/ng-bootstrap

After Installation import it in your root module and register it in @NgModule imports` array

import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
@NgModule({
  declarations: [AppComponent, ...],
  imports: [NgbModule.forRoot(), ...],
  bootstrap: [AppComponent]
})

NOTE
ng-bootstrap requires Bootstrap's 4 css to be added in your project. you need to Install it explicitly via:
npm install bootstrap@4 --save In your angular.json add the file paths to the styles array in under build target

   "styles": [
      "src/styles.css",
      "node_modules/bootstrap/dist/css/bootstrap.min.css"
   ],

P.S Do Restart Your server

i didn't solve the problem, sadly. but managed to make to codes work (almost all of my codes have this probelm btw) the local issuer certificate problem happens under python3.7 so i changed back to python2.7 QAQ and all that needed to change including "from urllib2 import urlopen" instead of "from urllib.request import urlopen" so sad...

If you use version 26 then inside dependencies version should be 1.0.1 and 3.0.1 i.e., as follows

  androidTestImplementation 'com.android.support.test:runner:1.0.1'
  androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'

If you use version 27 then inside dependencies version should be 1.0.2 and 3.0.2 i.e., as follows

  androidTestImplementation 'com.android.support.test:runner:1.0.2'
  androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

As mentioned above by @Gustavo GeoDrones you can find your Cam URL using https://www.ispyconnect.com/sources.aspx.

Go to the website, click on the model of your camera and a "Cam Video URL Generator" will appear. Insert your IP, username, etc. and click on "generate".

Cam URL for my Canon VB-H45 is (of course with my specific username, password and IP):

http://username:password@IP/-wvhttp-01-/video.cgi

The final code:

cap = cv2.VideoCapture('http://username:password@IP/-wvhttp-01-/video.cgi')

This issue is based on your installed version of visual studio and Windows, you can follow the following steps:-

1. Go to Command Window

2. downgraded your PCL by the following command

   Install-Package Xamarin.Forms -Version 2.5.1.527436
   

3. Rebuild Your Project.
4. Now You will able to see the required output

My solution is to check the version number of pip and use the import the correct main function correctly

    import pip

    if int(pip.__version__.split('.')[0])>9:
        from pip._internal import main
    else:
        from pip import main
    def install(package):
        main(['install', package])

If you want to update any specific version from the package.json you can update the version of the package by doing ==>

yarn add package-name@version-number

or

npm install --save package-name@version-number

If you want to update all packages to the latest version you can run command ==>

npm audit fix --force

I faced the same problem, like mentioned above I tried these.

1. Installed JDK 1.8 and set my JAVA_HOME env to 1.8 - This did not work
2. My Android studio didn't show any "Android SDK Tools (Obsolete)" but had had an "Android SDK Tools"

This is what worked for me:

1. Delete the "Android SDK Tools" from SDK Manager
2. Reinstall it by first deselecting the "Hide Obsolete Packages" and then select "Android SDK Tools (Obsolete)", install it.
3. run flutter doctor --android-licenses and select y for the prompts
4. run flutter doctor and everything will be fine!!!!

Upgrade pip as follows:

curl https://bootstrap.pypa.io/get-pip.py | python

Note: You may need to use sudo python above if not in a virtual environment.

What's happening:

Python.org sites are stopping support for TLS versions 1.0 and 1.1. This means that Mac OS X version 10.12 (Sierra) or older will not be able to use pip unless they upgrade pip as above.

(Note that upgrading pip via pip install --upgrade pip will also not upgrade it correctly. It is a chicken-and-egg issue)

This thread explains it (thanks to this Twitter post):

Mac users who use pip and PyPI:

If you are running macOS/OS X version 10.12 or older, then you ought to upgrade to the latest pip (9.0.3) to connect to the Python Package Index securely:

curl https://bootstrap.pypa.io/get-pip.py | python

and we recommend you do that by April 8th.

Pip 9.0.3 supports TLSv1.2 when running under system Python on macOS < 10.13. Official release notes: https://pip.pypa.io/en/stable/news/

Also, the Python status page:

Completed - The rolling brownouts are finished, and TLSv1.0 and TLSv1.1 have been disabled. Apr 11, 15:37 UTC

Update - The rolling brownouts have been upgraded to a blackout, TLSv1.0 and TLSv1.1 will be rejected with a HTTP 403 at all times. Apr 8, 15:49 UTC

Lastly, to avoid other install errors, make sure you also upgrade setuptools after doing the above:

pip install --upgrade setuptools

props.children represents the content between the opening and the closing tags when invoking/rendering a component:

const Foo = props => (
  <div>
    <p>I'm {Foo.name}</p>
    <p>abc is: {props.abc}</p>

    <p>I have {props.children.length} children.</p>
    <p>They are: {props.children}.</p>
    <p>{Array.isArray(props.children) ? 'My kids are an array.' : ''}</p>
  </div>
);

const Baz = () => <span>{Baz.name} and</span>;
const Bar = () => <span> {Bar.name}</span>;

invoke/call/render Foo:

<Foo abc={123}>
  <Baz />
  <Bar />
</Foo>

In case someone doesn't fix the problem use methods above. I fixed mine by surrounding the async func by an arrow function. As in:

describe("Profile Tab Exists and Clickable: /settings/user", () => {
    test(`Assert that you can click the profile tab`, (() => {
      async () => {
        await page.waitForSelector(PROFILE.TAB)
        await page.click(PROFILE.TAB)
      }
    })(), 30000);
});

For those who are looking for making TextField or TextFormField accept only numbers as input, try this code block :

for flutter 1.20 or newer versions

TextFormField(
              controller: _controller,
              keyboardType: TextInputType.number,
              inputFormatters: <TextInputFormatter>[
                FilteringTextInputFormatter.allow(RegExp(r'[0-9]')),
              ],
              decoration: InputDecoration(
                  labelText: "whatever you want",
                  hintText: "whatever you want",
                  icon: Icon(Icons.phone_iphone)))

for earlier versions of 1.20

TextFormField(
    controller: _controller,
    keyboardType: TextInputType.number,
    inputFormatters: <TextInputFormatter>[
        WhitelistingTextInputFormatter.digitsOnly
    ],
    decoration: InputDecoration(
        labelText:"whatever you want", 
        hintText: "whatever you want",
        icon: Icon(Icons.phone_iphone)
    )
)

If you want to push or pull your files from devices monitor now android studio offers something better then android monitor. Just take a look at right side of your studio there is an option device file explorer. Open it and you are good to go. Select your device from top dropdown and rest of everything is pretty much the same as it was in android monitor. Below is the screen Shot attached to give you the exact location and idea.

This also happened to me but using Dynamic Features. I already had Java 8 compatibility enabled in the app module but I had to add this compatibility lines to the Dynamic Feature module and then it worked.

Add the line below in application.properties file under resource folder and restart your application.

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration

If you want to do this only once, then do it because The framework will call initState() method exactly once for each State object it creates.

 @override
  void initState() {
    super.initState();
    WidgetsBinding.instance
        .addPostFrameCallback((_) => executeAfterBuildComplete(context));
  }

If you want to do this again and again like on back or navigate to a next screen and etc..., then do it because didChangeDependencies() Called when a dependency of this State object changes.

For example, if the previous call to build referenced an InheritedWidget that later changed, the framework would call this method to notify this object about the change.

This method is also called immediately after initState. It is safe to call BuildContext.dependOnInheritedWidgetOfExactType from this method.

 @override
  void didChangeDependencies() {
    super.didChangeDependencies();
    WidgetsBinding.instance
        .addPostFrameCallback((_) => executeAfterBuildComplete(context));
  }

This is the your Callback function

executeAfterBuildComplete([BuildContext context]){
    print("Build Process Complete");
  }

The following steps work for me:

1. npm cache clean -f
2. rm -rf node_modules
3. npm i

In my case, this error ocurred while i was using the

implementation 'com.android.support:appcompat-v7:+'
implementation 'com.android.support:design:+'

libraries together with googles

implementation 'com.google.android.material:material-components:+'

library. If this is the case in your project, i highly recommend to fully remove the google material components library from your project.

On Windows 10;

Goto C:\ProgramData\ComposerSetup\bin

Edit: composer.bat and add memory_limit=-1 in the last line as shown below.

@echo OFF
:: in case DelayedExpansion is on and a path contains ! 
setlocal DISABLEDELAYEDEXPANSION
php -d memory_limit=-1 "%~dp0composer.phar" %*

Problem solved ;)

I had the same issue and I installed this cordova plugin and problem solved.

cordova plugin add cordova-android-support-gradle-release --save

If you are trying to connect to a MySQL server from a text-based MySQL client from another computer (be it Docker or not)

Most answers here involve connecting from a desktop client, or ask you to switch to an older authentication method. If you're connecting it with the MySQL client (text-based), I made it work with a Debian Buster in a Docker container.

Say you have the apt system and wget set up, do the following:

1. sudo apt-get update
2. sudo apt-get install lsb-release -y
3. Download a Debian package which update apt sources for you from the MySQL web site.
4. sudo dpkg -i mysql-apt-config_0.8.13-1_all.deb and select the options you want. In my case I only need MySQL Tools & Connectors to be enabled.
5. sudo apt-get update
6. sudo apt-get install mysql-client -y
7. Done. You can now run the new MySQL client and connect with the new authentication method.

I've set up my Android SDK manually with the command line, and I was able to solve this kind of errors while I tried to set up my development environment, if you want to solve it as I did, just follow the next steps that I posted in a GitHub Comment in a related issue:

https://github.com/flutter/flutter/issues/19805#issuecomment-478306166

I hope this can help anyone need it! Bye!

I downgrade the support

previously it was
implementation 'com.android.support:appcompat-v7:27.0.2'

Use it

implementation 'com.android.support:appcompat-v7:27.1.0'

implementation 'com.android.support:design:27.1.0'

Its Working Happy Codng

This happened to me because I was using:

app.datasource.url=jdbc:mysql://localhost/test

When I replaced url by jdbc-url then it worked:

app.datasource.jdbc-url=jdbc:mysql://localhost/test

If you want to use Unix shell commands on Windows, you can use Windows Powershell, which includes both Windows and Unix commands as aliases. You can find more info on it in the documentation.

PowerShell supports aliases to refer to commands by alternate names. Aliasing allows users with experience in other shells to use common command names that they already know for similar operations in PowerShell.

The PowerShell equivalents may not produce identical results. However, the results are close enough that users can do work without knowing the PowerShell command name.

In IntelliJ:

1. Open Project Structure (?;) > Modules > YOUR MODULE -> Language level: set 9, in your case.
2. Repeat for each module.

Looks like you forgot the mode parameter when calling open, try w:

file = open("copy.txt", "w") 
file.write("Your text goes here") 
file.close() 

The default value is r and will fail if the file does not exist

'r' open for reading (default)
'w' open for writing, truncating the file first

Other interesting options are

'x' open for exclusive creation, failing if the file already exists
'a' open for writing, appending to the end of the file if it exists

See Doc for Python2.7 or Python3.6

-- EDIT --

As stated by chepner in the comment below, it is better practice to do it with a withstatement (it guarantees that the file will be closed)

with open("copy.txt", "w") as file:
    file.write("Your text goes here")

use this command

sudo usermod -aG docker $USER

then restart your computer this worked for me.

Just go to File > Settings > Languages & Frameworks > Dart

Click on check box Enable Dart Support for project 'projectName' Paste the Dart SDK path.

This is how you get Dart SDK path, follow the given steps copy the Dart SDK Path, which is in Flutter SDK, Go to location where your Flutter SDK Situated, then,

Flutter/bin/cache/dart-sdk , till dart-sdk, copy the path and paste it.

Peer dependency warnings, more often than not, can be ignored. The only time you will want to take action is if the peer dependency is missing entirely, or if the version of a peer dependency is higher than the version you have installed.

Let's take this warning as an example:

npm WARN @angular/[email protected] requires a peer of @angular/[email protected] but none is installed. You must install peer dependencies yourself.

With Angular, you would like the versions you are using to be consistent across all packages. If there are any incompatible versions, change the versions in your package.json, and run npm install so they are all synced up. I tend to keep my versions for Angular at the latest version, but you will need to make sure your versions are consistent for whatever version of Angular you require (which may not be the most recent).

In a situation like this:

npm WARN [email protected] requires a peer of @angular/core@^2.4.0 || ^4.0.0 but none is installed. You must install peer dependencies yourself.

If you are working with a version of Angular that is higher than 4.0.0, then you will likely have no issues. Nothing to do about this one then. If you are using an Angular version under 2.4.0, then you need to bring your version up. Update the package.json, and run npm install, or run npm install for the specific version you need. Like this:

npm install @angular/[email protected] --save

You can leave out the --save if you are running npm 5.0.0 or higher, that version saves the package in the dependencies section of the package.json automatically.

In this situation:

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: [email protected] (node_modules\fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

You are running Windows, and fsevent requires OSX. This warning can be ignored.

Hope this helps, and have fun learning Angular!

$(document).on('change', '.custom-file-input', function (event) {
    $(this).next('.custom-file-label').html(event.target.files[0].name);
})

Best of all worlds. Works on dynamically created inputs, and uses actual file name.

if you don't need to pass arguments to function, just remove () from function like below:

<td><span onClick={this.toggle}>Details</span></td>

but if you want to pass arguments, you should do like below:

<td><span onClick={(e) => this.toggle(e,arg1,arg2)}>Details</span></td>

BS4 is now available on .NET Core 2.2. On the SDK 2.2.105 x64 installer for sure. I'm running Visual Studio 2017 with it. So far so good for new web application projects.

Pickle is a module installed for both Python 2 and Python 3 by default. See the standard library for 3.6.4 and 2.7.

Also to prove what I am saying is correct try running this script:

import pickle
print(pickle.__doc__)

This will print out the Pickle documentation showing you all the functions (and a bit more) it provides.

Or you can start the integrated Python 3.6 Module Docs and check there.

As a rule of thumb: if you can import the module without an error being produced then it is installed

The reason for the No matching distribution found for pickle is because libraries for included packages are not available via pip because you already have them (I found this out yesterday when I tried to install an integrated package).

If it's running without errors but it doesn't work as expected I would think that you made a mistake somewhere (perhaps quickly check the functions you are using in the docs). Python is very informative with it's errors so we generally know if something is wrong.

replace "150x150" with 720x720 and remove /vp/ from the link.it should work.

In my case, I was transport class component from parent and use it inside as a prop var, using typescript and Formik, and run well like this:

Parent 1

import Parent2 from './../components/Parent2/parent2'
import Parent3 from './../components/Parent3/parent3'

export default class Parent1 extends React.Component {
  render(){
    <React.Fragment>
      <Parent2 componentToFormik={Parent3} />
    </React.Fragment>
  }
}

Parent 2

export default class Parent2 extends React.Component{
  render(){
    const { componentToFormik } = this.props
    return(
    <Formik 
      render={(formikProps) => {
        return(
          <React.fragment>
            {(new componentToFormik(formikProps)).render()}
          </React.fragment>
        )
      }}
    />
    )
  }
}

Windows 10:

Android Studio -> File -> Other Settings -> Default Project Structure... -> JDK location:

copy string shown, such as:

C:\Program Files\Android\Android Studio\jre

In file locator directory window, right-click on "This PC" ->

Properties -> Advanced System Settings -> Environment Variables... -> System Variables

click on the New... button under System Variables, then type and paste respectively:

.......Variable name: JAVA_HOME

.......Variable value: C:\Program Files\Android\Android Studio\jre

and hit OK buttons to close out.

Some installations may require JRE_HOME to be set as well, the same way.

To check, open a NEW black console window, then type echo %JAVA_HOME% . You should get back the full path you typed into the system variable. Windows 10 seems to support spaces in the filename paths for system variables very well, and does not seem to need ~tilde eliding.

As an alternative, you can install 7.1 version of mcrypt and create a symbolic link to it:

Install php7.1-mcrypt:

sudo apt install php7.1-mcrypt

Create a symbolic link:

sudo ln -s /etc/php/7.1/mods-available/mcrypt.ini /etc/php/7.2/mods-available

After enabling mcrypt by sudo phpenmod mcrypt, it gets available.

I think this is the minimal code to implement it:

i=0,a={valueOf:()=>++i}_x000D_
_x000D_
if (a == 1 && a == 2 && a == 3) {_x000D_
  console.log('Mind === Blown');_x000D_
}

Creating a dummy object with a custom valueOf that increments a global variable i on each call. 23 characters!

I know that question is a bit old but

In root of project where Pipfile is located you could run

pipenv --venv

which returns

/Users/your_user_name/.local/share/virtualenvs/model-N-S4uBGU

and then remove this env by typing

rm -rf /Users/your_user_name/.local/share/virtualenvs/model-N-S4uBGU

In Gradle build file, add dependency:

implementation 'com.android.support:multidex:1.0.2'

or

implementation 'com.android.support:multidex:1.0.3'

or

implementation 'com.android.support:multidex:2.0.0'

And then in the "defaultConfig" section, add:

multiDexEnabled true

Under targetSdkVersion

minSdkVersion 17
targetSdkVersion 27
multiDexEnabled true

Now if you encounter this error

Error:Failed to resolve: multidex-instrumentation Open File

You need to change your gradle to 3.0.1

classpath 'com.android.tools.build:gradle:3.0.1'

And put the following code in the file gradle-wrapper.properties

distributionUrl=https://services.gradle.org/distributions/gradle-4.1-all.zip

Finally

add class Applition in project And introduce it to the AndroidManifest Which is extends from MultiDexApplication

public class App extends MultiDexApplication {

    @Override
    public void onCreate( ) {
        super.onCreate( );
    }
}

Run the project first to create an error, then clean the project

Finally, Re-launch the project and enjoy it

I got the same issue and then I checked that I wrote:

<base href="./"> in index.html

Then I changed to

<base href="/">

And then it worked fine.

Install Qt

sudo apt-get install build-essential

sudo apt-get install qtcreator

sudo apt-get install qt5-default

Install documentation and examples If Qt Creator is installed thanks to the Ubuntu Sofware Center or thanks to the synaptic package manager, documentation for Qt Creator is not installed. Hitting the F1 key will show you the following message : "No documentation available". This can easily be solved by installing the Qt documentation:

sudo apt-get install qt5-doc

sudo apt-get install qt5-doc-html qtbase5-doc-html

sudo apt-get install qtbase5-examples

Restart Qt Creator to make the documentation available.

Error while loading shared libraries

Problem:

radiusd: error while loading shared libraries: libfreeradius-radius-2.1.10.so: cannot open shared object file: No such file or directory

Reason:

Actually, the libraries have been installed in a place where dynamic linker cannot find it.

Solution:

While this is not a guarantee but using the following command may help you solve the “cannot open shared object file” error:

sudo /sbin/ldconfig -v

ModelSim-Altera error

This error can also show up if there are parts in your string that json.loads() does not recognize. An in this example string, an error will be raised at character 27 (char 27).

string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""

My solution to this would be to use the string.replace() to convert these items to a string:

import json

string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""

string = string.replace("False", '"False"')

dict_list = json.loads(string)

I had this problem too. It turned out I forgot to include one of the components in app.module.ts

in the manifest file set second activity parentActivityName as first activity and remove the screenOrientation parameter to the second activity. it means your first activity is the parent and decide to an orientation of your second activity.

<activity
        android:name=".view.FirstActiviy"
        android:screenOrientation="portrait"
        android:theme="@style/AppTheme" />

<activity
        android:name=".view.SecondActivity"
        android:parentActivityName=".view.FirstActiviy"
        android:theme="@style/AppTheme.Transparent" />

I found the solution as Its problem with Android Studio 3.1 Canary 6

My backup of Android Studio 3.1 Canary 5 is useful to me and saved my half day.

Now My build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.2'
    defaultConfig {
        applicationId "com.example.demo"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true
    }
    dataBinding {
        enabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors {
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
    implementation "com.android.support:design:${rootProject.ext.supportLibVersion}"
    implementation "com.android.support:support-v4:${rootProject.ext.supportLibVersion}"
    implementation "com.android.support:recyclerview-v7:${rootProject.ext.supportLibVersion}"
    implementation "com.android.support:cardview-v7:${rootProject.ext.supportLibVersion}"
    implementation "com.squareup.retrofit2:retrofit:2.3.0"
    implementation "com.google.code.gson:gson:2.8.2"
    implementation "com.android.support.constraint:constraint-layout:1.0.2"
    implementation "com.squareup.retrofit2:converter-gson:2.3.0"
    implementation "com.squareup.okhttp3:logging-interceptor:3.6.0"
    implementation "com.squareup.picasso:picasso:2.5.2"
    implementation "com.dlazaro66.qrcodereaderview:qrcodereaderview:2.0.3"
    compile 'com.github.elevenetc:badgeview:v1.0.0'
    annotationProcessor 'com.github.elevenetc:badgeview:v1.0.0'
    testImplementation "junit:junit:4.12"
    androidTestImplementation("com.android.support.test.espresso:espresso-core:3.0.1", {
        exclude group: "com.android.support", module: "support-annotations"
    })
}

and My gradle is:

classpath 'com.android.tools.build:gradle:3.1.0-alpha06'

and its working finally.

I think there problem in Android Studio 3.1 Canary 6

Thank you all for your time.

Jest's setupFiles is the proper way to handle this, and you need not install dotenv, nor use an .env file at all, to make it work.

jest.config.js:

module.exports = {
  setupFiles: ["<rootDir>/.jest/setEnvVars.js"]
};

.jest/setEnvVars.js:

process.env.MY_CUSTOM_TEST_ENV_VAR = 'foo'

That's it.

tested on Debian, should works on Ubuntu:

1.) First download latest phpMyadmin file.

2.) Delete (make a backup) all previous version file located in /usr/share/phpmyadmin directory.

3.) Uncompress to /usr/share/phpmyadmin/ directory all files of latest phpmyadmin.

4.) Modify file libraries/vendor_config.php and change line:

define('CONFIG_DIR', '');

to

define('CONFIG_DIR', '/etc/phpmyadmin/');

and

define('TEMP_DIR', './tmp/');

to

define('TEMP_DIR', '/tmp/');

5.) restart apache server and done.

This is rather old question but this might be of some help for future reference. Delete node_modules folder and run npm install again. Worked for me.

For me it was the http://localhost instead of https://localhost.

The corrected code is

import urllib.request
fhand = urllib.request.urlopen('http://data.pr4e.org/romeo.txt')
counts = dict()
for line in fhand: 
    words = line.decode().split() 
for word in words: 
    counts[word] = counts.get(word, 0) + 1 
print(counts) 

running the code above produces

{'Who': 1, 'is': 1, 'already': 1, 'sick': 1, 'and': 1, 'pale': 1, 'with': 1, 'grief': 1}

If your pdf is text-based and not a scanned document (i.e. if you can click and drag to select text in your table in a PDF viewer), then you can use the module camelot-py with

import camelot
tables = camelot.read_pdf('foo.pdf')

You then can choose how you want to save the tables (as csv, json, excel, html, sqlite), and whether the output should be compressed in a ZIP archive.

tables.export('foo.csv', f='csv', compress=False)

Edit: tabula-py appears roughly 6 times faster than camelot-py so that should be used instead.

import camelot
import cProfile
import pstats
import tabula

cmd_tabula = "tabula.read_pdf('table.pdf', pages='1', lattice=True)"
prof_tabula = cProfile.Profile().run(cmd_tabula)
time_tabula = pstats.Stats(prof_tabula).total_tt

cmd_camelot = "camelot.read_pdf('table.pdf', pages='1', flavor='lattice')"
prof_camelot = cProfile.Profile().run(cmd_camelot)
time_camelot = pstats.Stats(prof_camelot).total_tt

print(time_tabula, time_camelot, time_camelot/time_tabula)

gave

1.8495559890000015 11.057014036000016 5.978199147125147

In order to use Http in your app you will need to add the HttpModule to your app.module.ts:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule, ErrorHandler } from '@angular/core';
import { HttpModule } from '@angular/http';
...
  imports: [
    BrowserModule,
    HttpModule,
    IonicModule.forRoot(MyApp),
    IonicStorageModule.forRoot()
  ]

EDIT

As mentioned in the comment below, HttpModule is deprecated now, use import { HttpClientModule } from '@angular/common/http'; Make sure HttpClientModule in your imports:[] array

Just add the .vs folder to the .gitignore file.

Here is the template for Visual Studio from GitHub's collection of .gitignore templates, as an example:
https://github.com/github/gitignore/blob/master/VisualStudio.gitignore

If you have any trouble adding the .gitignore file, just follow these steps:

1. On the Team Explorer's window, go to Settings.

2. Then access Repository Settings.

3. Finally, click Add in the Ignore File section.

Done. ;)
This default file already includes the .vs folder.

This issue seems to like the following.

How to resolve repository certificate error in Gradle build

Below steps may help:

1. Add certificate to keystore-

Import some certifications into Android Studio JDK cacerts from Android Studio’s cacerts.

Android Studio’s cacerts may be located in

{your-home-directory}/.AndroidStudio3.0/system/tasks/cacerts

I used the following import command.

$ keytool -importkeystore -v -srckeystore {src cacerts} -destkeystore {dest cacerts}

2. Add modified cacert path to gradle.properties-

systemProp.javax.net.ssl.trustStore={your-android-studio-directory}\\jre\\jre\\lib\\security\\cacerts
systemProp.javax.net.ssl.trustStorePassword=changeit

Ref : https://www.cresco.co.jp/blog/entry/2014//

I know this has been answered but wanted to provide alternate solution for anyone in the future:

You can use .loc to subset the dataframe by only values that are notnull(), and then subset out the 'x' column only. Take that same vector, and apply(int) to it.

If column x is float:

df.loc[df['x'].notnull(), 'x'] = df.loc[df['x'].notnull(), 'x'].apply(int)

Do not use authorization instead of authentication. I should get whole access to service all clients with header. The working code is :

public class TokenAuthenticationHandler : AuthenticationHandler<TokenAuthenticationOptions> 
{
    public IServiceProvider ServiceProvider { get; set; }

    public TokenAuthenticationHandler (IOptionsMonitor<TokenAuthenticationOptions> options, ILoggerFactory logger, UrlEncoder encoder, ISystemClock clock, IServiceProvider serviceProvider) 
        : base (options, logger, encoder, clock) 
    {
        ServiceProvider = serviceProvider;
    }

    protected override Task<AuthenticateResult> HandleAuthenticateAsync () 
    {
        var headers = Request.Headers;
        var token = "X-Auth-Token".GetHeaderOrCookieValue (Request);

        if (string.IsNullOrEmpty (token)) {
            return Task.FromResult (AuthenticateResult.Fail ("Token is null"));
        }           

        bool isValidToken = false; // check token here

        if (!isValidToken) {
            return Task.FromResult (AuthenticateResult.Fail ($"Balancer not authorize token : for token={token}"));
        }

        var claims = new [] { new Claim ("token", token) };
        var identity = new ClaimsIdentity (claims, nameof (TokenAuthenticationHandler));
        var ticket = new AuthenticationTicket (new ClaimsPrincipal (identity), this.Scheme.Name);
        return Task.FromResult (AuthenticateResult.Success (ticket));
    }
}

Startup.cs :

#region Authentication
services.AddAuthentication (o => {
    o.DefaultScheme = SchemesNamesConst.TokenAuthenticationDefaultScheme;
})
.AddScheme<TokenAuthenticationOptions, TokenAuthenticationHandler> (SchemesNamesConst.TokenAuthenticationDefaultScheme, o => { });
#endregion

And mycontroller.cs

[Authorize(AuthenticationSchemes = SchemesNamesConst.TokenAuthenticationDefaultScheme)]
public class MainController : BaseController
{ ... }

I can't find TokenAuthenticationOptions now, but it was empty. I found the same class PhoneNumberAuthenticationOptions :

public class PhoneNumberAuthenticationOptions : AuthenticationSchemeOptions
{
    public Regex PhoneMask { get; set; }// = new Regex("7\\d{10}");
}

You should define static class SchemesNamesConst. Something like:

public static class SchemesNamesConst
{
    public const string TokenAuthenticationDefaultScheme = "TokenAuthenticationScheme";
}

You are getting error for HttpClient so, you are missing HttpClientModule for that.

You should import it in app.module.ts file like this -

import { HttpClientModule } from '@angular/common/http';

and mention it in the NgModule Decorator like this -

@NgModule({
...
imports:[ HttpClientModule ]
...
})

If this even doesn't work try clearing cookies of the browser and try restarting your server. Hopefully it may work, I was getting the same error.

I am using Android Studio 3.0 and was facing the same problem. I add this to my gradle:

multiDexEnabled true

And it worked!

Example

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.1'
    defaultConfig {
        applicationId "com.xx.xxx"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        multiDexEnabled true //Add this
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            shrinkResources true
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

And clean the project.

If you are using Android Studio 3.0 or above make sure your project build.gradle should have content similar to-

buildscript {                 
    repositories {
        google()
        jcenter()
    }
    dependencies {            
        classpath 'com.android.tools.build:gradle:3.0.1'

    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

Note- position really matters add google() before jcenter()

And for below Android Studio 3.0 and starting from support libraries 26.+ your project build.gradle must look like this-

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

check these links below for more details-

1- Building Android Apps

2- Add Build Dependencies

3- Configure Your Build

I had the same problem in docker and these steps worked for me:

apt update

then:

apt install libsm6 libxext6 libxrender-dev

For me what fixed this error was changing one line in my app's gradle dependencies.

from this:

compile('com.google.android.gms:play-services-gcm:+') {
    force = true
}

To this:

compile('com.google.android.gms:play-services-gcm:11.8.0') {
    force = true
}

Today I have the similar problem.

Previous in my project gradle

// Top-level build file where you can add configuration options common to all 
sub-projects/modules.
allprojects {
repositories {
    jcenter()
    google()
    mavenCentral()
    maven { url "https://jitpack.io" }
    maven { url 'https://plugins.gradle.org/m2/'}
}}

Then I just added this below line in allprojects

maven {
        url "https://maven.google.com"
    }

It saved my day.

And now my current allproject {} code looks like this

allprojects {
repositories {
    jcenter()
    google()
    mavenCentral()
    maven { url "https://jitpack.io" }
    maven { url 'https://plugins.gradle.org/m2/'}
    maven {
        url "https://maven.google.com"
    }
}}

In case the error appears when upgrading from Laravel 6 to Laravel 7, the command composer require laravel/ui "^2.0" solves the problem (see https://laravel.com/docs/7.x/upgrade#authentication -scaffolding)

simple way is to move your files to be read under the same folder of your python file, then you just need to use the name of the file, without calling another path.

In case of shared hosting when you do not have command line access simply navigate to laravel/bootstrap/cache folder and delete (or rename) config.php and you are all done!

As stated in the official migration guide, this error is encountered when:

Your app includes a build type that a library dependency does not

android {
  buildTypes {
      release {
          ...
      }
      dexOptions {
          ...
        // release & debug is in project animators
        matchingFallbacks = ['release', 'debug']
      }
      debug {
          ...
      }
    }
}

Correct place to find the info is now this documentation

npm i -f

I'd like to repost some comments from this thread, where you can read up on the issue and the issue was solved.

This is exactly Angular's issue. Current package.json requires fsevent as not optionalDependencies but devDependencies. This may be a problem for non-OSX users.

Sometimes

Even if you remove it from package.json npm i still fails because another module has it as a peer dep.

So

if npm-shrinkwrap.json is still there, please remove it or try npm i -f

This feature was added in 1.45, demoed here.

Launch the command palette Ctrl+Shift+P, run Publish to Github, and follow the prompt. You will be given the choice between a private and public repository, so be careful that you choose the right one.

It may ask you to login to github. It will then prompt for the repo name (defaults to the name of the folder), and for creating a .gitignore file (defaults to empty .gitignore). Just hit enter if you are fine with the defaults. When you are done it should give you a popup notification in the bottom right with a link to the repo https://github.com/<username>/<reponame>

Minor warning: if your project already has a .gitignore file in it this process will overwrite it

I just set chrome as my default browser and jupyter launches in Chrome now.

However, we have also the following approach, but it did not work for me:

"CONDA version 4.7.5 and jupyter 6.0.0. - Windows 10"

1) Open Anaconda and launch your environment in terminal

2) Create config file and open file in notepad

3) Modify line of NotebookApp with chrome and save modification

4) Launch Jupyter

:( ... but it still launches in Mozilla.

For me the issue was that my local CLI was not the same version as my global CLI - updating it by running the following command solved the problem:

npm install --save-dev @angular/cli@latest

Trigger a change detection by using ChangeDetectorRef in the refresh() method just after receiving the new data, inject ChangeDetectorRef in the constructor and use detectChanges like this:

import { Component, OnInit, ChangeDetectorRef } from '@angular/core';
import { LanguageModel, LANGUAGE_DATA } from '../../../../models/language.model';
import { LanguageAddComponent } from './language-add/language-add.component';
import { AuthService } from '../../../../services/auth.service';
import { LanguageDataSource } from './language-data-source';
import { LevelbarComponent } from '../../../../directives/levelbar/levelbar.component';
import { DataSource } from '@angular/cdk/collections';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/of';
import { MatSnackBar, MatDialog } from '@angular/material';

@Component({
  selector: 'app-language',
  templateUrl: './language.component.html',
  styleUrls: ['./language.component.scss']
})
export class LanguageComponent implements OnInit {
  displayedColumns = ['name', 'native', 'code', 'level'];
  teachDS: any;

  user: any;

  constructor(private authService: AuthService, private dialog: MatDialog,
              private changeDetectorRefs: ChangeDetectorRef) { }

  ngOnInit() {
    this.refresh();
  }

  add() {
    this.dialog.open(LanguageAddComponent, {
      data: { user: this.user },
    }).afterClosed().subscribe(result => {
      this.refresh();
    });
  }

  refresh() {
    this.authService.getAuthenticatedUser().subscribe((res) => {
      this.user = res;
      this.teachDS = new LanguageDataSource(this.user.profile.languages.teach);
      this.changeDetectorRefs.detectChanges();
    });
  }
}

Make a virtual enviroment using python3

virtualenv env_name --python="python3"

and run the following command

pip3 install opencv-python

This reply may be late but it may help users having similar problem. The opencv-contrib (available at https://github.com/opencv/opencv_contrib/releases) contains extra modules but the build procedure has to be done from core opencv (available at from https://github.com/opencv/opencv/releases) modules.

Follow below steps (assuming you are building it using CMake GUI)

1. Download openCV (from https://github.com/opencv/opencv/releases) and unzip it somewhere on your computer. Create build folder inside it

2. Download exra modules from OpenCV. (from https://github.com/opencv/opencv_contrib/releases). Ensure you download the same version.

3. Unzip the folder.

4. Open CMake

5. Click Browse Source and navigate to your openCV folder.

6. Click Browse Build and navigate to your build Folder.

7. Click the configure button. You will be asked how you would like to generate the files. Choose Unix-Makefile from the drop down menu and Click OK. CMake will perform some tests and return a set of red boxes appear in the CMake Window.

8. Search for "OPENCV_EXTRA_MODULES_PATH" and provide the path to modules folder (e.g. /Users/purushottam_d/Programs/OpenCV3_4_5_contrib/modules)

9. Click Configure again, then Click Generate.

10. Go to build folder

# cd build
# make
# sudo make install

11. This will install the opencv libraries on your computer.

Just need to add version of which you want

upgrade or downgrade

npm install -g npm@version

Example if you want to downgrade from npm 5.6.0 to 4.6.1 then,

npm install -g [email protected]

It is tested on linux

v-flex does not have a display flex! Inspect v-flex in your browser and you will find out it is just a simple block div.

So, you should override it with display: flex in your HTML or CSS to make it work with justify-content.

I faced the same problem. Though I am a little bit backdated developer (Still using windows to develop :P)

To solve this issue on windows :

STEP 1: Install jdk 8 if it wasn't installed (jdk 9 or 11 doesn't work but you may have them installed for using in other dev uses).

Very simple using Chocolatey:

choco install jdk8

(If installed using Chocolatey, skip steps 2 and 3)

STEP 2: Go to the Environment variables settings and set JAVA_HOME TO jdk 8's installation directory.

STEP 3: Go to path variable and add bin directory of jdk 8 and move it to top.

STEP 4: Close any open terminal sessions and restart a new session

OPTIONAL STEP 5: Depending on your objective in the terminal run (may need to add sdkmanager to path or just navigate to the directory):

sdkmanager --update

That's all! :O Enjoy fluttering! :D

I have same problem with pipenv on Mac OS X 10.13 High Seirra, another Mac works just fine. I use Heroku to deploy my Django servers, some in 2.7 and some in 3.6. So, I need both 2.7 and 3.6. When HomeBrew install Python, it keeps python points to original 2.7, and python3 points to 3.6.

The problem might due to $ pip install pipenv. I checked /usr/local/bin and pipenv isn't there. So, I tried a full uninstall:

$ pip uninstall pipenv

Cannot uninstall requirement pipenv, not installed
You are using pip version 9.0.1, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

$ pip3 uninstall pipenv
Skipping pipenv as it is not installed.

Then reinstall and works now:

$ pip3 install pipenv
Collecting pipenv

Faced the same problem. 'conda update' does not work; It gives the error : "CondaValueError: no package names supplied"

On executing the following commands, I was able to launch the Anaconda navigator:

conda update -n base conda

conda update anaconda-navigator

This worked for me:

-> uninstalled Jupyter
-> install jupyter in Python36 folder
-> open Jupyter from command prompt instead of git bash.

In my case, Unfortunately, neither Michel's nor Suragch's solutions worked for me.

So I solved this issue by doing the following:

In gradle:3.0 the compile configuration is now deprecated and should be replaced by implementation or api. For more information you can read here You can read the official docs at Gradle Build Tool

The compile configuration still exists but should not be used as it will not offer the guarantees that the api and implementation configurations provide.

it's better to use implementation or api rather compile

just replace compile with implementation, debugCompile with debugImplementation, testCompile with testImplementation and androidtestcompile with androidTestImplementation

For example: Instead of this

compile 'com.android.support:appcompat-v7:26.0.2'
compile 'com.android.support:support-v4:26.1.0'
compile 'com.github.bumptech.glide:glide:4.0.0'

use like this

implementation 'com.android.support:appcompat-v7:26.0.2'
implementation 'com.android.support:support-v4:26.1.0'
implementation 'com.github.bumptech.glide:glide:4.0.0'

After that

• Delete the .gradle folder inside your project ( Note that, in order to see .gradle, you need to switch to the "Project" view in the navigator on the top left )
• Delete all the build folders and the gradle cache.
• From the Build menu, press the Clean Project button.
• After task completed, press the Rebuild Project button from the Build menu.

Hope it will helps !

What I did is moved the dependencies list to the end of

#Pods for <app>

In Podfile. Like this:

    # Uncomment the next line to define a global platform for your project
    # platform :ios, '9.0'

    target '<app>' do
    # Comment the next line if you don't want to use dynamic frameworks
    use_frameworks!

  # Pods for <app>

  target '<app>Tests' do
    inherit! :search_paths
    # Pods for testing
  end

  target '<app>UITests' do
    inherit! :search_paths
    # Pods for testing
  end

    pod 'Firebase/Core'
    pod 'Firebase/Database'

end

Still looking for a solution? I got mine from this link .

All I had to do was add this two lines of code at the top of "public static void Main" method in the "program class".

 var logRepo = LogManager.GetRepository(Assembly.GetEntryAssembly());
 XmlConfigurator.Configure(logRepo, new FileInfo("log4net.config"));

Yes, you have to add:

1. Microsoft.Extensions.Logging.Log4Net.AspNetCore using NuGet.
2. A text file with the name of log4net.config and change the property(Copy to Output Directory) of the file to "Copy if Newer" or "Copy always".

You can also configure your asp.net core application in such a way that everything that is logged in the output console will be logged in the appender of your choice. You can also download this example code from github and see how i configured it.

You can write:

python
import keras
keras.__version__

For each error of the form:

npm WARN {something} requires a peer of {other thing} but none is installed. You must install peer dependencies yourself.

You should:

$ npm install --save-dev "{other thing}"

Note: The quotes are needed if the {other thing} has spaces, like in this example:

npm WARN [email protected] requires a peer of rollup@>=0.66.0 <2 but none was installed.

Resolved with:

$ npm install --save-dev "rollup@>=0.66.0 <2"

To fix this problem, you have to install OpenSSL development package, which is available in standard repositories of all modern Linux distributions.

To install OpenSSL development package on Debian, Ubuntu or their derivatives:

$ sudo apt-get install libssl-dev

To install OpenSSL development package on Fedora, CentOS or RHEL:

$ sudo yum install openssl-devel 

Edit : As @isapir has pointed out, for Fedora version>=22 use the DNF package manager :

dnf install openssl-devel

I had approximately the same problem with Laravel 5.5 on ubuntu, finally i've found a solution here to switch between the versions of php used by apache :

1. sudo a2dismod php5
2. sudo a2enmod php7.1
3. sudo service apache2 restart

and it works

Your file structure says that folder name is Container with a capital C. But you are trying to import it by container with a lowercase c. You will need to change the import or the folder name because the paths are case sensitive.

After changed API version 9.0 getting the error Cleartext HTTP traffic to YOUR-API.DOMAIN.COM not permitted (targetSdkVersion="28"). in xamarin, xamarin.android and android studio.

Two steps to solve this error in xamarin, xamarin.android and android studio.

Step 1: Create file resources/xml/network_security_config.xml

In network_security_config.xml

<?xml version="1.0" encoding="utf-8" ?>
<network-security-config>
  <domain-config cleartextTrafficPermitted="true">
    <domain includeSubdomains="true">mobapi.3detrack.in</domain>
  </domain-config>
</network-security-config>

Step 2: update AndroidManifest.xml -

Add android:networkSecurityConfig="@xml/network_security_config" on application tag. e.g:

<application android:label="your App Name" android:icon="@drawable/icon" android:networkSecurityConfig="@xml/network_security_config">

I had same problems with Sublime Text.

I came up with following solution: I just edited

tsconfig.json

in the root of Angular workspace to include my freshly created application.

 {
  "files": [],
  "references": [
    {

    }

so this happened to me on windows recently. I fix it by following the following steps using a PowerShell with admin privileges:

1. delete node_modulesfolder
2. running npm install --global windows-build-tools
3. reinstalling node modules or node-sass with npm install

The answer has been given by Faisal Khurshid and Michael_B already.
This is just an attempt to make a possible solution more obvious.

For IE11 and below you need to enable grid's older specification in the parent div e.g. body or like here "grid" like so:

.grid-parent{display:-ms-grid;}

then define the amount and width of the columns and rows like e.g. so:

.grid-parent{
  -ms-grid-columns: 1fr 3fr;
  -ms-grid-rows: 4fr;
}

finally you need to explicitly tell the browser where your element (item) should be placed in e.g. like so:

.grid-item-1{
  -ms-grid-column: 1;
  -ms-grid-row: 1;
}

.grid-item-2{
  -ms-grid-column: 2;
  -ms-grid-row: 1;
}

When you create a new ASP.NET Core 2.0 application, this hook is included by default. In previous versions of EF Core and ASP.NET Core, the tools try to invoke Startup.ConfigureServices directly in order to obtain the application's service provider, but this pattern no longer works correctly in ASP.NET Core 2.0 applications. If you are upgrading an ASP.NET Core 1.x application to 2.0, you can modify your Program class to follow the new pattern.

public class BloggingContextFactory : IDesignTimeDbContextFactory<BloggingContext>
    {
        public BloggingContext CreateDbContext(string[] args)

            var optionsBuilder = new DbContextOptionsBuilder<BloggingContext>();
            optionsBuilder.UseSqlite("Data Source=blog.db");

            return new BloggingContext(optionsBuilder.Options);
        }

I had that problem. And I found this solve. In Android Studio, Open File menu, and go to Project Structure, In Module app, go to dependencies tab and you can add 'com.google.android.gms:play-services:x.x.x' by clicking on + button.

In powershell you should use ${pwd} vs $(pwd)

You need to install popperjs along with bootstrap to get rid of this error.Note that if you are using "bootstrap": "^4.4.1", and @popperjs/core v2.x combinations,bootstrap may not support popperjs version. So downgrade your version.

Option 1: npm install popper.js@^1.12.9 --save

and Add following script between jquery and bootstrap scripts.

"node_modules/popper.js/dist/umd/popper.min.js",

Option 2: Add following script tag to index.html

<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js" integrity="sha384-b/U6ypiBEHpOf/4+1nzFpr53nxSS+GLCkfwBdFNTxtclqqenISfwAzpKaMNFNmj4" crossorigin="anonymous"></script

Just in case someone else encounters this problem. You need to call

window.location.reload()

And you cannot call this from a expression. If you want to call this from a click event you need to put this on a function:

(click)="realodPage()"

And simply define the function:

reloadPage() {
   window.location.reload();
}

If you are changing the route, it might not work because the click event seems to happen before the route changes. A very dirty solution is just to add a small delay

reloadPage() {
    setTimeout(()=>{
      window.location.reload();
    }, 100);
}

You could make the webpage scroll down to a position where you can't see the address bar, and if the user scrolls, the page should return to your set position. In that way, Mobile browsers when scrolled down , will try to guve you full-screen experience. So it will hide the address bar. I don't know the code, someone else might put up the code.

If you are trying to make more than just one folder on the root of the sdcard, ex. Environment.getExternalStorageDirectory() + "/Example/Ex App/"

then instead of folder.mkdir() you would use folder.mkdirs()

I've made this mistake in the past & I took forever to figure it out.

I'm not sure if this is quite what you're looking for but I've had a lot of success using an HTML to Postscript converter html2ps to create postscript copies of web pages, which I then convert to .gif or .pngs

This doesn't produce exact screenshot quality that you'd get from a web browser and doesn't handle complicated things like flash or css all that well, but the advantage is that you can run it on the web server.

(I use it to create thumbnails of user created content, for navigation)

Another answer with later print/format style is:

res[0]=12
res[1]=23
print("my num is 0x{0:02x}{1:02x}".format(res[0],res[1]))

This is probably unlikely, but given that your observed behaviour is unusual it needs to be checked and no-one else has mentioned it.

Are you absolutely sure that all objects are owned by dbo and you don't have a rogue copies owned by yourself or a different user present as well?

Just occasionally when I've seen odd behaviour it's because there was actually two copies of an object and which one you get depends on what is specified and who you are logged on as. For example it is perfectly possible to have two copies of a view or procedure with the same name but owned by different owners - a situation that can arise where you are not logged onto the database as a dbo and forget to specify dbo as object owner when you create the object.

In note that in the text you are running some things without specifying owner, eg

sp_recompile ViewOpener

if for example there where two copies of viewOpener present owned by dbo and [some other user] then which one you actually recompile if you don't specify is dependent upon circumstances. Ditto with the Report_Opener view - if there where two copies (and they could differ in specification or execution plan) then what is used depends upon circumstances - and as you do not specify owner it is perfectly possible that your adhoc query might use one and the compiled procedure might use use the other.

As I say, it's probably unlikely but it is possible and should be checked because your issues could be that you're simply looking for the bug in the wrong place.

For the particular case of Windows 10 October 2018 Update or later activedirectory module is not available unless the optional feature RSAT: Active Directory Domain Services and Lightweight Directory Services Tools is installed (instructions here + uncollapse install instructions).

Reopen Windows Powershell and import-module activedirectory will work as expected.

It appears that without the class constraint:

bool Compare<T> (T x, T y) where T: class
{
    return x == y;
}

One should realize that while class constrained Equals in the == operator inherits from Object.Equals, while that of a struct overrides ValueType.Equals.

Note that:

bool Compare<T> (T x, T y) where T: struct
{
    return x == y;
}

also gives out the same compiler error.

As yet I do not understand why having a value type equality operator comparison is rejected by the compiler. I do know for a fact though, that this works:

bool Compare<T> (T x, T y)
{
    return x.Equals(y);
}

You should be able to && the conditions:

ng-disabled="condition1 && condition2"

I was getting this on an asp.net 2.0 iis7 Windows2008 site. Same code on iis6 worked fine. It was causing an issue for me because it was messing up the login process. User would login and get a 302 to default.asxp, which would get through page_load, but not as far as pre-render before iis7 would send a 302 back to login.aspx without the auth cookie. I started playing with app pool settings, and for some reason 'enable 32 bit applications' seems to have fixed it. No idea why, since this site isn't doing anything special that should require any 32 bit drivers. We have some sites that still use Access that require 32bit, but not our straight SQL sites like this one.

You got a bunch of good answers, so I'll just throw out a suggestion. If you are going to be working on this project for more than 2 days, download eclipse or netbeans and build your project in there.

If you are not normally a java programmer, then the help it will give you will be invaluable.

It's not worth the 1/2 hour download/install if you are only spending 2 hours on it.

Both have hotkeys/menu items to "Fix imports", with this you should never have to worry about imports again.

Too many comments to make to different answers, so I'll leave another answer here.

You can and should use reinterpret_cast<>, in your case

str.append(reinterpret_cast<const char*>(foo()));

because, while these two are different types, the 2014 standard, chapter 3.9.1 Fundamental types [basic.fundamental] says there is a relationship between them:

Plain char, signed char and unsigned char are three distinct types, collectively called narrow character types. A char, a signed char, and an unsigned char occupy the same amount of storage and have the same alignment requirements (3.11); that is, they have the same object representation.

(selection is mine)

Here's an available link: https://en.cppreference.com/w/cpp/language/types#Character_types

Using wchar_t for Unicode/multibyte strings is outdated: Should I use wchar_t when using UTF-8?

Doing it in one bulk read:

import re

textfile = open(filename, 'r')
filetext = textfile.read()
textfile.close()
matches = re.findall("(<(\d{4,5})>)?", filetext)

Line by line:

import re

textfile = open(filename, 'r')
matches = []
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += reg.findall(line)
textfile.close()

But again, the matches that returns will not be useful for anything except counting unless you added an offset counter:

import re

textfile = open(filename, 'r')
matches = []
offset = 0
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += [(reg.findall(line),offset)]
    offset += len(line)
textfile.close()

But it still just makes more sense to read the whole file in at once.

This was helpful to use in COGNOS because creating a SQL "Not in" statement in Cognos was allowed, but it took too long to run. I had manually coded table A to join to table B in in Cognos as A.key "not in" B.key, but the query was taking too long/not returning results after 5 minutes.

For anyone else that is looking for a "NOT IN" solution in Cognos, here is what I did. Create a Query that joins table A and B with a LEFT JOIN in Cognos by selecting link type: table A.Key has "0 to N" values in table B, then added a Filter (these correspond to Where Clauses) for: table B.Key is NULL.

Ran fast and like a charm.

Okku's post worked for me in Edge. In order to get desired result on the iPhone, I had to use:

<thead class="sticky-top">

which didn't effect Edge.

If you set the cell formatting to Text prior to adding a numeric value with a leading zero, the leading zero is retained without having to skew results by adding an apostrophe. If you try and manually add a leading zero value to a default sheet in Excel and then convert it to text, the leading zero is removed. If you convert the cell to Text first, then add your value, it is fine. Same principle applies when doing it programatically.

        // Pull in all the cells of the worksheet
        Range cells = xlWorkBook.Worksheets[1].Cells;
        // set each cell's format to Text
        cells.NumberFormat = "@";
        // reset horizontal alignment to the right
        cells.HorizontalAlignment = XlHAlign.xlHAlignRight;

        // now add values to the worksheet
        for (i = 0; i <= dataGridView1.RowCount - 1; i++)
        {
            for (j = 0; j <= dataGridView1.ColumnCount - 1; j++)
            {
                DataGridViewCell cell = dataGridView1[j, i];
                xlWorkSheet.Cells[i + 1, j + 1] = cell.Value.ToString();
            }
        }

If there is a version mismatch between nvcc and nvidia-smi then different versions of cuda are used as driver and run time environemtn.

To ensure same version of CUDA drivers are used what you need to do is to get CUDA on system path.

First run whereis cuda and find the location of cuda driver.

Then go to .bashrc and modify the path variable and set the directory precedence order of search using variable 'LD_LIBRARY_PATH'.

for instance

$ whereis cuda
cuda: /usr/lib/cuda /usr/include/cuda.h /usr/local/cuda

CUDA is installed at /usr/local/cuda, now we need to to .bashrc and add the path variable as:

vim  ~/.bashrc
export PATH="/usr/local/cuda/bin:${PATH}"

and after this line set the directory search path as:

export LD_LIBRARY_PATH="/usr/local/cuda/lib64:${LD_LIBRARY_PATH}"

Then save the .bashrc file. And refresh it as:

$ source ~/.bashrc

This will ensure you have nvcc -V and nvidia-smi to use the same version of drivers.

So, not directly related but this is the first question that appears when you try to find how to terminate a process running from a specific folder using Python.

It also answers the question in a way(even though it is an old one with lots of answers).

While creating a faster way to scrape some government sites for data I had an issue where if any of the processes in the pool got stuck they would be skipped but still take up memory from my computer. This is the solution I reached for killing them, if anyone knows a better way to do it please let me know!

import pandas as pd
import wmi
from re import escape
import os

def kill_process(kill_path, execs):
    f = wmi.WMI()
    esc = escape(kill_path)
    temp = {'id':[], 'path':[], 'name':[]}
    for process in f.Win32_Process():
        temp['id'].append(process.ProcessId)
        temp['path'].append(process.ExecutablePath)
        temp['name'].append(process.Name)
    temp = pd.DataFrame(temp)
    temp = temp.dropna(subset=['path']).reset_index().drop(columns=['index'])
    temp = temp.loc[temp['path'].str.contains(esc)].loc[temp.name.isin(execs)].reset_index().drop(columns=['index'])
    [os.system('taskkill /PID {} /f'.format(t)) for t in temp['id']]

Swift solution:

Define an Outlet:

@IBOutlet weak var pickerView: UIPickerView!  // for example

Then in your viewWillAppear or your viewDidLoad, for example, you can use the following:

pickerView.selectRow(rowMin, inComponent: 0, animated: true)
pickerView.selectRow(rowSec, inComponent: 1, animated: true)

If you inspect the Swift 2.0 framework you'll see .selectRow defined as:

func selectRow(row: Int, inComponent component: Int, animated: Bool) 

option clicking .selectRow in Xcode displays the following:

1) Install Git for Windows from here: http://git-scm.com/download/win

2) Note: During installation, Make sure "Use Git and optional Unix tools from the windows command prompt" is selected

3) restart the Android Studio and try again

4) Go to File-> New -> Project from version control -> Git

Copy it over. It's really that simple. :)

On the client side, just edit .git/config in the client's local repo to point your remotes to the new URL as necessary.

While it is not casting per se; I have found https://github.com/JohnWhiteTB/TypedJSON to be a useful alternative.

@JsonObject
class Person {

    @JsonMember
    lastName: string;

    public getFullname() {
        return this.firstName + " " + this.lastName;
    }
}
var person = TypedJSON.parse('{ "firstName": "John", "lastName": "Doe" }', Person);

person instanceof Person; // true
person.getFullname(); // "John Doe"

Need to change remote url to ssh or https

git remote set-url origin [email protected]:laravel/laravel.git

I have tried but above not working after research found below the solution.

SELECT * FROM my_table where DATE(start_date) > '2011-01-01';

Well with some tweaks and use of timedelta here we go:

from datetime import datetime, timedelta


def inc_date(origin_date):
    day = origin_date.day
    month = origin_date.month
    year = origin_date.year
    if origin_date.month == 12:
        delta = datetime(year + 1, 1, day) - origin_date
    else:
        delta = datetime(year, month + 1, day) - origin_date
    return origin_date + delta

final_date = inc_date(datetime.today())
print final_date.date()

Update (2016-11-01)

I was using AmplifyJS mentioned below to work around this issue. However, for Safari in Private browsing, it was falling back to a memory-based storage. In my case, it was not appropriate because it means the storage is cleared on refresh, even if the user is still in private browsing.

Also, I have noticed a number of users who are always browsing in Private mode on iOS Safari. For that reason, a better fallback for Safari is to use cookies (if available). By default, cookies are still accessible even in private browsing. Of course, they are cleared when exiting the private browsing, but they are not cleared on refresh.

I found the local-storage-fallback library. From the documentation:

Purpose

With browser settings like "Private Browsing" it has become a problem to rely on a working window.localStorage, even in newer browsers. Even though it may exist, it will throw exceptions when trying to use setItem or getItem. This module will run appropriate checks to see what browser storage mechanism might be available, and then expose it. It uses the same API as localStorage so it should work as a drop-in replacement in most cases.

Beware of the gotchas:

• CookieStorage has storage limits. Be careful here.
• MemoryStorage will not persist between page loads. This is more or less a stop-gap to prevent page crashes, but may be sufficient for websites that don't do full page loads.

TL;DR:

Use local-storage-fallback (unified API with .getItem(prop) and .setItem(prop, val)):

Check and use appropriate storage adapter for browser (localStorage, sessionStorage, cookies, memory)

Original answer

To add upon previous answers, one possible workaround would be to change the storage method. There are a few librairies such as AmplifyJS and PersistJS which can help. Both libs allow persistent client-side storage through several backends.

For AmplifyJS

localStorage

• IE 8+
• Firefox 3.5+
• Safari 4+
• Chrome
• Opera 10.5+
• iPhone 2+
• Android 2+

sessionStorage

• IE 8+
• Firefox 2+
• Safari 4+
• Chrome
• Opera 10.5+
• iPhone 2+
• Android 2+

globalStorage

• Firefox 2+

userData

• IE 5 - 7
• userData exists in newer versions of IE as well, but due to quirks in IE 9's implementation, we don't register userData if localStorage is supported.

memory

• An in-memory store is provided as a fallback if none of the other storage types are available.

For PersistentJS

• flash: Flash 8 persistent storage.
• gears: Google Gears-based persistent storage.
• localstorage: HTML5 draft storage.
• globalstorage: HTML5 draft storage (old spec).
• ie: Internet Explorer userdata behaviors.
• cookie: Cookie-based persistent storage.

They offer an abstraction layer so you don't have to worry about choosing the storage type. Keep in mind there might be some limitations (such as size limits) depending on the storage type though. Right now, I am using AmplifyJS, but I still have to do some more testing on iOS 7/Safari/etc. to see if it actually solves the problem.

With background you can set all background properties like:

• background-color
• background-image
  
• background-repeat
  
• background-position
  etc.

With background-color you can just specify the color of the background

background: url(example.jpg) no-repeat center center #fff;

VS.

background-image: url(example.jpg);
background-position: center center;
background-repeat: no-repeat;
background-color: #fff;

pandas provides high level data manipulation tools built on top of NumPy. NumPy by itself is a fairly low-level tool, similar to MATLAB. pandas on the other hand provides rich time series functionality, data alignment, NA-friendly statistics, groupby, merge and join methods, and lots of other conveniences. It has become very popular in recent years in financial applications. I will have a chapter dedicated to financial data analysis using pandas in my upcoming book.

Paint.net is a free photo-editing tool that allows for transparent backgrounds. There is a simple example on YouTube http://www.youtube.com/watch?v=cdFpS-AvNCE. If you are still on Windows XP SP2 and that's an issue, I would first recommend doing the free service pack upgrade. But if that is not an option there are older versions of Paint.net that you could download and try.

If you are using require.js than need to add window.$ = window.jQuery = require('jquery') in app.js

OR you can make dependent file load after parent file loaded.. such as below concept

require.config({
    baseUrl: "scripts/appScript",
    paths: {
        'jquery':'jQuery/jquery.min',
        'bootstrap':'bootstrap/bootstrap.min' 
    },
   shim
    shim: {
        'bootstrap':['jquery'],
        },

    // kick start application
    deps: ['app']
});

Above code shown that bootstrap is dependent on Jquery so i have added in shim and make it dependent

Using This Method To Get All Range Without Error

 public List<T> GetTsRate( List<T> AllT,int Index,int Count)

            try
            {
                Ts = AllT.ToList().GetRange(Index, Count);
            }
            catch (Exception ex)
            {
                Ts = AllT.Skip(Index).ToList();
            }
            return Ts ;
        }

let now = new Date();
let timestamp = now.getFullYear().toString();
let month = now.getMonth() + 1;
timestamp += (month < 10 ? '0' : '') + month.toString();
timestamp += (now.getDate() < 10 ? '0' : '') + now.getDate().toString();
timestamp += (now.getHours() < 10 ? '0' : '') + now.getHours().toString();
timestamp += (now.getMinutes() < 10 ? '0' : '') + now.getMinutes().toString();
timestamp += (now.getSeconds() < 10 ? '0' : '') + now.getSeconds().toString();

You can choose the following UIView extension to get it (credit by Daniel):

extension UIView {
    var firstResponder: UIView? {
        guard !isFirstResponder else { return self }
        return subviews.first(where: {$0.firstResponder != nil })
    }
}

Today I got this error, and I just did a small workaround which was too simple.

1. Close all of your chrome instances, that you might have opened before you opened Visual Studio.
2. Now stop debugging and run your application again.

You will not get the error again and if the debugger doesn't hit, refresh the browser again.

Update (12-Dec-2018):

I just tested this bug in Visual Studio 2019 preview, it seems like the bug is fixed now.

Hope this helps.

If the HTMLElement is input[type='button'], input[type='submit'], etc.

<input id="ShowButton" type="button" value="Show">
<input id="ShowButton" type="submit" value="Show">

change it using this code:

document.querySelector('#ShowButton').value = 'Hide';

If, the HTMLElement is button[type='button'], button[type='submit'], etc:

<button id="ShowButton" type="button">Show</button>
<button id="ShowButton" type="submit">Show</button>

change it using any of these methods,

document.querySelector('#ShowButton').innerHTML = 'Hide';
document.querySelector('#ShowButton').innerText = 'Hide';
document.querySelector('#ShowButton').textContent = 'Hide';

Please note that

• input is an empty tag and cannot have innerHTML, innerText or textContent
• button is a container tag and can have innerHTML, innerText or textContent

Ignore this answer if you ain't using asp.net-web-forms, asp.net-ajax and rad-grid

You must use value instead of innerHTML.

Try this.

document.getElementById("ShowButton").value= "Hide Filter";

And since you are running the button at server the ID may get mangled in the framework. I so, try

document.getElementById('<%=ShowButton.ClientID %>').value= "Hide Filter";

Another better way to do this is like this.

On markup, change your onclick attribute like this. onclick="showFilterItem(this)"

Now use it like this

function showFilterItem(objButton) {
    if (filterstatus == 0) {
        filterstatus = 1;
        $find('<%=FileAdminRadGrid.ClientID %>').get_masterTableView().showFilterItem();
        objButton.value = "Hide Filter";
    }
    else {
        filterstatus = 0;
        $find('<%=FileAdminRadGrid.ClientID %>').get_masterTableView().hideFilterItem();
        objButton.value = "Show filter";
    }
}

You say

I mean that it is not in use by any other application. If an application is using a port others can't use it until it becomes free.

But you can always connect to a port while others are using it if something's listening there. Otherwise, http port 80 would be a mess.

If your

   c = new TcpClient(ip, port);

fails, then nothing's listening there. Otherwise, it will connect, even if some other machine/application has a socket open to that ip and port.

    print(f'Copy {df.shape[0]} rows to S3 Bucket {bucket} at {filepath}, Done!')

copy_to_s3(client=s3, df=df_to_upload, bucket='abc', filepath='def/test.csv')

This should further clarify the points:

a = int(raw_input('Enter the index'))
str1 = 'Example'
leng = len(str1)
if (a < (len-1)) and (a > (-len)):
    print str1[a]
else:
    print('Index overflow')

        return !isNaN(obj - parseFloat(obj));
    }
}

output without strict mode:

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

Simplest solution that worked for me that I don't see mentioned in this thread:

I have multiple versions of Python installed but was trying to use Python3.7 -- so I had to use:

sudo pip3.7 install <package>

Are you sure, that specified database and table exists? Did you try to look at your database using any database client? For example command-line MySQL client bundled with MySQL server. Or if you a developer newbie, there are dozens of a GUI and web interface clients (HeidiSQL, MySQL Workbench, phpMyAdmin and many more). So first check, if your table creation script was successful and had created what it have to.

BTW why do you have a script for creating the database structure? It's usualy a nonrecurring operation, so write the script to do this is unneeded. It's useful only in case of need of repeatedly creating and manipulating the database structure on the fly.

Some practical uses for the [Serializable] attribute:

• Saving object state using binary serialisation; you can very easily 'save' entire object instances in your application to a file or network stream and then recreate them by deserialising - check out the BinaryFormatter class in System.Runtime.Serialization.Formatters.Binary
• Writing classes whose object instances can be stored on the clipboard using Clipboard.SetData() - nonserialisable classes cannot be placed on the clipboard.
• Writing classes which are compatible with .NET Remoting; generally, any class instance you pass between application domains (except those which extend from MarshalByRefObject) must be serialisable.

These are the most common usage cases that I have come across.

Building on @yunzen's great answer:

I'm guessing many people searching for this topic are trying use a large image as a "hero" background image, for example on a homepage. In this case, they would often want text to appear over the image and to have it scale down well on mobile devices.

Here is the perfect CSS for such a background image (use it on the <img> tag):

/* Set left edge of inner element to 50% of the parent element */
margin-left: 50%;

/* Move to the left by 50% of own width */
transform: translateX(-50%);

/* Scale image...(101% - instead of 100% - avoids possible 1px white border on left of image due to rounding error */
width: 101%;

/* ...but don't scale it too small on mobile devices - adjust this as needed */
min-width: 1086px;

/* allow content below image to appear on top of image */
position: absolute;
z-index: -1;

/* OPTIONAL - try with/without based on your needs */
top: 0;

/* OPTIONAL - use if your outer element containing the img has "text-align: center" */
left: 0;

In your AppDelegate file inside func application method

let statusBar: UIView = application.value(forKey: "statusBar") as! UIView
statusBar.backgroundColor = .red

All answers above are incomplete, the problem here lies in linker ld rather than compiler collect2: ld returned 1 exit status. When you are compiling your fib.c to object:

$ gcc -c fib.c
$ nm fib.o
0000000000000028 T fibo
                 U floor
                 U _GLOBAL_OFFSET_TABLE_
0000000000000000 T main
                 U pow
                 U printf

Where nm lists symbols from object file. You can see that this was compiled without an error, but pow, floor, and printf functions have undefined references, now if I will try to link this to executable:

$ gcc fib.o
fib.o: In function `fibo':
fib.c:(.text+0x57): undefined reference to `pow'
fib.c:(.text+0x84): undefined reference to `floor'
collect2: error: ld returned 1 exit status

Im getting similar output you get. To solve that, I need to tell linker where to look for references to pow, and floor, for this purpose I will use linker -l flag with m which comes from libm.so library.

$ gcc fib.o -lm
$ nm a.out

You can now see, functions pow, floor are linked to GLIBC_2.2.5.

Parameters order is important too, unless your system is configured to use shared librares by default, my system is not, so when I issue:

$ gcc -lm fib.o
fib.o: In function `fibo':
fib.c:(.text+0x57): undefined reference to `pow'
fib.c:(.text+0x84): undefined reference to `floor'
collect2: error: ld returned 1 exit status

Note -lm flag before object file. So in conclusion, add -lm flag after all other flags, and parameters, to be sure.

HashMap<String, String> meMap=new HashMap<String, String>();
meMap.put("Color1","Red");
meMap.put("Color2","Blue");
meMap.put("Color3","Green");
meMap.put("Color4","White");
Iterator iterator = meMap.keySet().iterator();
while( iterator. hasNext() ){
    Toast.makeText(getBaseContext(), meMap.get(iterator.next().toString()), 
    Toast.LENGTH_SHORT).show();
}

In similar situations, I've done well by putting something like the following into /etc/rc.local:

cd /path/to/my/script
./my_script.py &
cd -
echo `date +%Y-%b-%d_%H:%M:%S` > /tmp/ran_rc_local  # check that rc.local ran

This has worked on multiple versions of Fedora and on Ubuntu 14.04 LTS, for both python and perl scripts.

Here is the typescript version too:

JSONTryParse(input: any) {
    try {
        //check if the string exists
        if (input) {
            var o = JSON.parse(input);

            //validate the result too
            if (o && o.constructor === Object) {
                return o;
            }
        }
    }
    catch (e: any) {
    }

    return false;
};

If using Visual Studio 2010 you can right-click on the project for the service, and select properties. Then select the Web tab. Under the Servers section you can configure the URL. There is also a button to create the virtual directory.

My suggestion is the log file should always be logged above the root context of the webApp, so in case we redeploy the webApp, we don't want to override the existing log files.

Sudo is a Unix specific command designed to allow a user to carry out administrative tasks with the appropriate permissions.

Windows does not have (need?) this.

Run the command with the sudo removed from the start.

If someone is looking for another option for Git Lab and the options above do not work, then we have another option. For a local installation of Git Lab server, we have found that the approach, below, allows us to include the package dependency. We generated and use an access token to do so.

$ npm install --save-dev https://git.yourdomain.com/userOrGroup/gitLabProjectName/repository/archive.tar.gz?private_token=InsertYourAccessTokenHere

Of course, if one is using an access key this way, it should have a limited set of permissions.

Good luck!

The escape character in batch scripts is ^. But for double-quoted strings, double up the quotes:

"string with an embedded "" character"

You can use the command split for this task. For example this command entered into the command prompt

split YourLogFile.txt -b 500m

creates several files with a size of 500 MByte each. This will take several minutes for a file of your size. You can rename the output files (by default called "xaa", "xab",... and so on) to *.txt to open it in the editor of your choice.

Make sure to check the help file for the command. You can also split the log file by number of lines or change the name of your output files.

Just adding another thing that worked for me :

react-native link

Evidently my ReactNative files were no longer there. I could figure that out by clicking on

Build Phases -> Link Binary with Libraries ->

Then right clicking a file I knew was responsible for React, and clicking Show In Finder .

But nothing opened. So assuming the library went missing, I just ran the above command which relinked everything again.

Also if you havn't, try :

rm -rf node_modules/ && npm install

Newer versions of Android Studio include the Device File Explorer which I've found to be a handy GUI method of downloading files from my development Nexus 7.

You Must make sure you have enabled USB Debugging on the device

1. Click View > Tool Windows > Device File Explorer or click the Device File Explorer button in the tool window bar to open the Device File Explorer.
2. Select a device from the drop down list.

3. Interact with the device content in the file explorer window. Right-click on a file or directory to create a new file or directory, save the selected file or directory to your machine, upload, delete, or synchronize. Double-click a file to open it in Android Studio.

   Android Studio saves files you open this way in a temporary directory outside of your project. If you make modifications to a file you opened using the Device File Explorer, and would like to save your changes back to the device, you must manually upload the modified version of the file to the device.

Here's a sample method that adds two extra columns programmatically to the grid view:

    private void AddColumnsProgrammatically()
    {
        // I created these columns at function scope but if you want to access 
        // easily from other parts of your class, just move them to class scope.
        // E.g. Declare them outside of the function...
        var col3 = new DataGridViewTextBoxColumn();
        var col4 = new DataGridViewCheckBoxColumn();

        col3.HeaderText = "Column3";
        col3.Name = "Column3";

        col4.HeaderText = "Column4";
        col4.Name = "Column4";

        dataGridView1.Columns.AddRange(new DataGridViewColumn[] {col3,col4});
    }

A great way to figure out how to do this kind of process is to create a form, add a grid view control and add some columns. (This process will actually work for ANY kind of form control. All instantiation and initialization happens in the Designer.) Then examine the form's Designer.cs file to see how the construction takes place. (Visual Studio does everything programmatically but hides it in the Form Designer.)

For this example I created two columns for the view named Column1 and Column2 and then searched Form1.Designer.cs for Column1 to see everywhere it was referenced. The following information is what I gleaned and, copied and modified to create two more columns dynamically:

// Note that this info scattered throughout the designer but can easily collected.

        System.Windows.Forms.DataGridViewTextBoxColumn Column1;
        System.Windows.Forms.DataGridViewCheckBoxColumn Column2;

        this.Column1 = new System.Windows.Forms.DataGridViewTextBoxColumn();
        this.Column2 = new System.Windows.Forms.DataGridViewCheckBoxColumn();

        this.dataGridView1.Columns.AddRange(new System.Windows.Forms.DataGridViewColumn[] {
        this.Column1,
        this.Column2});

        this.Column1.HeaderText = "Column1";
        this.Column1.Name = "Column1";

        this.Column2.HeaderText = "Column2";
        this.Column2.Name = "Column2";

You can also use the filter function from the dplyr package which returns rows with matching conditions.

> library(dplyr)

> nrow(filter(aaa, sex == 1 & group1 == 2))
[1] 3
> nrow(filter(aaa, sex == 1 & group2 == "A"))
[1] 2

find your jre location ::sudo find / -name jre And then :: sudo update-alternatives --install /usr/bin/keytool keytool /opt/jdk/<jdk.verson>/jre/bin/keytool 100

In bootstrap 4, you can use 'w-100' class (w as width, and 100 as 100%)

You can find documentation here: https://getbootstrap.com/docs/4.0/utilities/sizing/

I followed a similar approach than the described in the other answers with a few tweaks based on the requirement I had, basically I created the following classes(Just in case, everything is Java):

public class Pair<L, R> {
    final L left;
    final R right;

    public Pair(L left, R right) {
        this.left = left;
        this.right = right;
    }

    public <T> T get(Class<T> param) {
        return (T) (param == this.left.getClass() ? this.left : this.right);
    }

    public static <L, R> Pair<L, R> of(L left, R right) {
        return new Pair<L, R>(left, right);
    }
}

Then, my requirement was simple, in the repository Class that reaches the DB, for the Get Methods than retrieve data from the DB, I need to check if it failed or succeed, then, if succeed, I needed to play with the returning list, if failed, stop the execution and notify the error.

So, for example, my methods are like this:

public Pair<ResultMessage, List<Customer>> getCustomers() {
    List<Customer> list = new ArrayList<Customer>();
    try {
    /*
    * Do some work to get the list of Customers from the DB
    * */
    } catch (SQLException e) {
        return Pair.of(
                       new ResultMessage(e.getErrorCode(), e.getMessage()), // Left 
                       null);  // Right
    }
    return Pair.of(
                   new ResultMessage(0, "SUCCESS"), // Left 
                   list); // Right
}

Where ResultMessage is just a class with two fields (code/message) and Customer is any class with a bunch of fields that comes from the DB.

Then, to check the result I just do this:

void doSomething(){
    Pair<ResultMessage, List<Customer>> customerResult = _repository.getCustomers();
    if (customerResult.get(ResultMessage.class).getCode() == 0) {
        List<Customer> listOfCustomers = customerResult.get(List.class);
        System.out.println("do SOMETHING with the list ;) ");
    }else {
        System.out.println("Raised Error... do nothing!");
    }
}

This is a quick and simple add of a named tab to the current worksheet:

Sheets.Add.Name = "Tempo"

If you are using Notepad++ editor Goto ctrl + F choose tab 3 find in files and enter:

1. Find What = text1*.*text2
2. Filters : .
3. Search mode = Regular Expression
4. Directory = enter the path of the directory you want to search in. You can check Follow current doc. to have the path of the current file to be filled.

Edit the gradle wrapper settings in gradle/wrapper/gradle-wrapper.properties and change gradle-1.6-bin.zip to gradle-2.4-bin.zip.

./gradle/wrapper/gradle-wrapper.properties :

It should compile without any error now.

Note: update version numbers with the most recent ones

The steps in order to make a full check are:

Prepare the captor :

ArgumentCaptor<SomeArgumentClass> someArgumentCaptor = ArgumentCaptor.forClass(SomeArgumentClass.class);

verify the call to dependent on component (collaborator of subject under test). times(1) is the default value, so ne need to add it.

verify(dependentOnComponent, times(1)).send(someArgumentCaptor.capture());

Get the argument passed to collaborator

SomeArgumentClass someArgument = messageCaptor.getValue();

someArgument can be used for assertions

In 2017, the solution is:

map.addListener('click', function(e) {
    placeMarker(e.latLng, map);
});

function placeMarker(position, map) {
    var marker = new google.maps.Marker({
        position: position,
        map: map
    });
    map.panTo(position);
}

This problem will occurred due to some unnecessary changes made in my.cnf file. Try to diff /etc/mysql/my.cnf with one of working mysql servers my.cnf file.

I just replaced /etc/mysql/my.cnf file with new my.cnf file and this works for me.

You can use islower() on your string to see if it contains some lowercase letters (amongst other characters). or it with isupper() to also check if contains some uppercase letters:

below: letters in the string: test yields true

>>> z = "(555) 555 - 5555 ext. 5555"
>>> z.isupper() or z.islower()
True

below: no letters in the string: test yields false.

>>> z= "(555).555-5555"
>>> z.isupper() or z.islower()
False
>>> 

Not to be mixed up with isalpha() which returns True only if all characters are letters, which isn't what you want.

Note that Barm's answer completes mine nicely, since mine doesn't handle the mixed case well.

I agree with the answer by Kenny Eliasson. Go with Extension methods. Here is a brief overview of extension methods and your required IfNotNull method.

Extension Methods ( IfNotNull method )

If you are using CSH or TCSH, here is a solution:

( find . > files_and_folders ) >& /dev/null

If you want output to the terminal:

( find . > /dev/tty ) >& /dev/null

However, as the "csh-whynot" FAQ describes, you should not use CSH.

That character is the BOM or "Byte Order Mark". It is usually received as the first few bytes of a file, telling you how to interpret the encoding of the rest of the data. You can simply remove the character to continue. Although, since the error says you were trying to convert to 'ascii', you should probably pick another encoding for whatever you were trying to do.

The problem I was having is that I was only using https for my GitHub account. I needed to make sure that my GitHub account was setup for ssh access and that GitHub and heroku were both using the same public keys. These are the steps I took:

1. Navigate to the ~/.ssh directory and delete the id_rsa and id_rsa.pub if they are there. I started with new keys, though it might not be necessary.

   $ cd ~/.ssh
   $ rm id_rsa id_rsa.pub
   

2. Follow the steps on gitHub to generate ssh keys

3. Login to heroku, create a new site and add your public keys:

   $ heroku login
   ...
   $ heroku create
   $ heroku keys:add
   $ git push heroku master
   

Extending bp's answer, I wanted to show you what he meant by immutable types.

First, this is okay:

>>> class TestB():
...     def __init__(self, attr=1):
...         self.attr = attr
...     
>>> a = TestB()
>>> b = TestB()
>>> a.attr = 2
>>> a.attr
2
>>> b.attr
1

However, this only works for immutable (unchangable) types. If the default value was mutable (meaning it can be replaced), this would happen instead:

>>> class Test():
...     def __init__(self, attr=[]):
...         self.attr = attr
...     
>>> a = Test()
>>> b = Test()
>>> a.attr.append(1)
>>> a.attr
[1]
>>> b.attr
[1]
>>> 

Note that both a and b have a shared attribute. This is often unwanted.

This is the Pythonic way of defining default values for instance variables, when the type is mutable:

>>> class TestC():
...     def __init__(self, attr=None):
...         if attr is None:
...             attr = []
...         self.attr = attr
...     
>>> a = TestC()
>>> b = TestC()
>>> a.attr.append(1)
>>> a.attr
[1]

The reason my first snippet of code works is because, with immutable types, Python creates a new instance of it whenever you want one. If you needed to add 1 to 1, Python makes a new 2 for you, because the old 1 cannot be changed. The reason is mostly for hashing, I believe.

EDIT: My former answer (based on answers in this thread) was not the way to go for me. I wanted a sub-menu to expand on mouse enter or touch click and to collapse on mouse leave or another touch click. Since mouse events normally are being fired after touch events, it was kind of tricky to write event listeners that support both touchscreen and mouse input at the same time.

jQuery plugin: Touch Or Mouse

I ended up writing a jQuery plugin called "Touch Or Mouse" (897 bytes minified) that can detect whether an event was invoked by a touchscreen or mouse (without testing for touch support!). This enables the support of both touchscreen and mouse at the same time and completely separate their events.

This way the OP can use touchstart or touchend for quickly responding to touch clicks and click for clicks invoked only by a mouse.

Demonstration

First one has to make ie. the body element track touch events:

$(document.body).touchOrMouse('init');

Mouse events our bound to elements in the default way and by calling $body.touchOrMouse('get', e) we can find out whether the event was invoked by a touchscreen or mouse.

$('.link').click(function(e) {
  var touchOrMouse = $(document.body).touchOrMouse('get', e);

  if (touchOrMouse === 'touch') {
    // Handle touch click.
  }
  else if (touchOrMouse === 'mouse') {
    // Handle mouse click.
  }
}

See the plugin at work at http://jsfiddle.net/lmeurs/uo4069nh.

Explanation

1. This plugin needs to be called on ie. the body element to track touchstart and touchend events, this way the touchend event does not have to be fired on the trigger element (ie. a link or button). Between these two touch events this plugin considers any mouse event to be invoked by touch.
2. Mouse events are fired only after touchend, when a mouse event is being fired within the ghostEventDelay (option, 1000ms by default) after touchend, this plugin considers the mouse event to be invoked by touch.
3. When clicking on an element using a touchscreen, the element gains the :active state. The mouseleave event is only fired after the element loses this state by ie. clicking on another element. Since this could be seconds (or minutes!) after the mouseenter event has been fired, this plugin keeps track of an element's last mouseenter event: if the last mouseenter event was invoked by touch, the following mouseleave event is also considered to be invoked by touch.

You can use GREATEST function with not nullable fields. If one of this values (or both) can be NULL, don't use it (result can be NULL).

select 
    if(
        fieldA is NULL, 
        if(fieldB is NULL, NULL, fieldB), /* second NULL is default value */
        if(fieldB is NULL, field A, GREATEST(fieldA, fieldB))
    ) as maxValue

You can change NULL to your preferred default value (if both values is NULL).

That should fit your needs:

var yourComponent = React.createClass({
    render: function () {
        return (
            <View style={{flex:1, flexDirection:'column', justifyContent:'center'}}>
                <View style={{flexDirection:'row'}}>
                    <TextInput style={{flex:0.8, borderWidth:1, height:20}}></TextInput>
                    <View style={{flex:0.2}}></View> // spacer
                </View>
            </View>
        );
    }
});

Addition to @icksde and @Korah (thx both!)

When building the options with AJAX the document.ready may be triggered before the list is built, so

This doesn't work

$(document).ready(function() {
    $("#gate").val('Gateway 2');
});

This does

A timeout does work but as @icksde says it's fragile (I did actually need 20ms in stead of 10ms). It's better to fit it inside the AJAX function like this:

$("#someObject").change(function() {
    $.get("website/page.php", {parameters}, function(data) {
        $("#gate").append("<option value='Gateway 2'">" + "Gateway 2" + "</option>");
        $("#gate").val('Gateway 2');
    }, "json");
});

You can use the react-moment package

-> https://www.npmjs.com/package/react-moment

Put in your file the next line:

import moment from "moment";

date_create: moment().format("DD-MM-YYYY hh:mm:ss")

Maybe this will help

After two dozens of comments to understand the situation, it was found that the libhdf5.so.7 was actually a symlink (with several levels of indirection) to a file that was not shared between the queued processes and the interactive processes. This means even though the symlink itself lies on a shared filesystem, the contents of the file do not and as a result the process was seeing different versions of the library.

For future reference: other than checking LD_LIBRARY_PATH, it's always a good idea to check a library with nm -D to see if the symbols actually exist. In this case it was found that they do exist in interactive mode but not when run in the queue. A quick md5sum revealed that the files were actually different.

Connection object is for illustration only. The DataAdapter is the key bit:

Dim strSql As String = "SELECT EmpCode,EmpID,EmpName FROM dbo.Employee"
Dim dtb As New DataTable
Using cnn As New SqlConnection(connectionString)
  cnn.Open()
  Using dad As New SqlDataAdapter(strSql, cnn)
    dad.Fill(dtb)
  End Using
  cnn.Close()
End Using

file --mime works, but not --mime-type. at least for my RHEL 5.

Edit AppServiceProvider.php will be found at app/Providers/AppServiceProvider.php and add

use Illuminate\Support\Facades\Schema;

public function boot()
{
Schema::defaultStringLength(191);
}

Then run

composer update

On your terminal. It helped me, may be it will work for you as well.

Google Apps Script is javascript, you can use all the string methods...

var grade = itemResponse.getResponse();
if(grade.indexOf("9th")>-1){do something }

You can find doc on many sites, this one for example.

There are plans for adding mix-ins soon, I believe.

But until then, go with the accepted answer. You can abstract that out a bit to make an "extendable" class:

class Extendable{
  private $extender=array();

  public function addExtender(Extender $obj){
    $this->extenders[] = $obj;
    $obj->setExtendee($this);
  }

  public function __call($name, $params){
    foreach($this->extenders as $extender){
       //do reflection to see if extender has this method with this argument count
       if (method_exists($extender, $name)){
          return call_user_func_array(array($extender, $name), $params);
       }
    }
  }
}


$foo = new Extendable();
$foo->addExtender(new OtherClass());
$foo->other_class_method();

Note that in this model "OtherClass" gets to 'know' about $foo. OtherClass needs to have a public function called "setExtendee" to set up this relationship. Then, if it's methods are invoked from $foo, it can access $foo internally. It will not, however, get access to any private/protected methods/variables like a real extended class would.

This is an old thread, but there doesn't seem to be an answer with code that addresses the issues with Anavanka's accepted answer: it doesn't work if you set the property in the viewmodel to false, or if you set your property to true, the user manually clicks on something else, and then you set it to true again. I couldn't get Zamotic's solution to work reliably in these cases either.

Pulling together some of the discussions above gives me the code below which does address these issues I think:

public static class FocusExtension
{
    public static bool GetIsFocused(DependencyObject obj)
    {
        return (bool)obj.GetValue(IsFocusedProperty);
    }

    public static void SetIsFocused(DependencyObject obj, bool value)
    {
        obj.SetValue(IsFocusedProperty, value);
    }

    public static readonly DependencyProperty IsFocusedProperty =
        DependencyProperty.RegisterAttached(
         "IsFocused", typeof(bool), typeof(FocusExtension),
         new UIPropertyMetadata(false, null, OnCoerceValue));

    private static object OnCoerceValue(DependencyObject d, object baseValue)
    {
        if ((bool)baseValue)
            ((UIElement)d).Focus();
        else if (((UIElement) d).IsFocused)
            Keyboard.ClearFocus();
        return ((bool)baseValue);
    }
}

Having said that, this is still complex for something that can be done in one line in codebehind, and CoerceValue isn't really meant to be used in this way, so maybe codebehind is the way to go.

You have set your %JAVA_HOME to jdk 1.7, but you are trying to compile using 1.8. Install jdk 1.8 and make sure your %JAVA_HOME points to that or drop the target release to 1.7.

Are you using C# 3.0? You can use object initializers like so:

static MyStruct[] myArray = 
            new MyStruct[]{
                new MyStruct() { id = 1, label = "1" },
                new MyStruct() { id = 2, label = "2" },
                new MyStruct() { id = 3, label = "3" }
            };

If the data to be encoded contains "exotic" characters, I think you have to encode in "UTF-8"

encoded = base64.b64encode (bytes('data to be encoded', "utf-8"))

If you have code in one subdirectory dependent on code in another subdirectory, you are probably better off with a single makefile at top-level.

See Recursive Make Considered Harmful for the full rationale, but basically you want make to have the full information it needs to decide whether or not a file needs to be rebuilt, and it won't have that if you only tell it about a third of your project.

With the introduction of globalThis in ES2020 you can use properties like.

For screen size:

globalThis.screen.availWidth 
globalThis.screen.availHeight

For Window Size

globalThis.outerWidth
globalThis.outerHeight

For Offset:

globalThis.pageXOffset
globalThis.pageYOffset

...& so on.

If using a commercial add-on to Selenium is an option for you, this is possible: Suppose your button is at coordinates x=123, y=456. Then you can use Helium to click on the element at these coordinates as follows:

from helium.api import *
# Tell Helium about your WebDriver instance:
set_driver(driver)
click(Point(123, 456))

(I am one of Helium's authors.)

Many problem for this, with my problem is missing '/' example: jquery-1.10.2.js:8720 XMLHttpRequest cannot load http://localhost:xxxProduct/getList_tagLabels/ It's must be: http://localhost:xxx/Product/getList_tagLabels/

One of my first projects as a programmer was a gem called stagecoach that (among other things) allowed the automatic adding of a github issue number to every commit message on a branch, which is a part of the question that hasn't really been answered.

Essentially when creating a branch you'd use a custom command (something like stagecoach -b <branch_name> -g <issue_number>), and the issue number would then be assigned to that branch in a yml file. There was then a commit hook that appended the issue number to the commit message automatically.

I wouldn't recommend it for production use as at the time I'd only been programming for a few months and I no longer maintain it, but it may be of interest to somebody.

In a broad view, we can define Intent as

When one Activity wants to start another activity it creates an Object called Intent that specifies which Activity it wants to start.

I have Samsung Galaxy S3 and it was not showing in the "Remote devices" tab nor in chrome://inspect. The device did show in Windows's Device Manager as GT-I9300, though. What worked for me was:

1. Plug the mobile phone to the front USB port
2. On my phone, click the notification about successful connection
3. Make sure the connection type is Camera (PTP)
4. On my Windows machine, download installer from https://github.com/koush/UniversalAdbDriver
5. Run it :)
6. Open cmd.exe
7. cd "C:\Program Files (x86)\ClockworkMod\Universal Adb Driver"
8. adb devices
9. Open Chrome in both mobile phone and Windows machine
10. On Windows's machine navigate to chrome://inspect - there, after a while you should see the target phone :)

I'm not sure if it affected the whole flow somehow, but at some point I've installed, and later uninstalled the drivers from Samsung: http://www.samsung.com/us/support/downloads/ > Mobile > Phones > Galaxy S > S III > Unlocked > http://www.samsung.com/us/support/owners/product/galaxy-s-iii-unlocked#downloads

In 2021 - use ES6 Template Literals for this task. If you need IE11 Support - use a transpiler.

let a = `something       something`;

Template Literals are fast, powerful and produce cleaner code.

If you need IE11 support and you don't have transpiler, stay strong and use \xa0 - it is a NO-BREAK SPACE char.

Reference from UTF-8 encoding table and Unicode characters, you can write as below:

var a = 'something' + '\xa0\xa0\xa0\xa0\xa0\xa0\xa0' + 'something';

I've written a jQuery plugin that incorporates the solutions discussed here with cross-browser support:

https://github.com/adjohnson916/jquery-methodOverride

Check it out!

 var miobj = [
  {"padreid":"0", "sw":"0", "dtip":"UNO", "datos":[]},
  {"padreid":"1", "sw":"0", "dtip":"DOS", "datos":[]}
 ];
 alert(miobj.length) //=== 2

but

 alert(miobj[0].length) //=== undefined

this function is very good

Object.prototype.count = function () {
    var count = 0;
    for(var prop in this) {
        if(this.hasOwnProperty(prop))
            count = count + 1;
    }
    return count;
}

alert(miobj.count()) // === 2
alert(miobj[0].count()) // === 4

git update-index function has several option you can find typing as below:

git update-index --help

Here you will find various option - how to handle with the function update-index.

[if you don't know the file name]

git update-index --really-refresh 

[if you know the file name ]

git update-index --no-assume-unchanged <file>

will revert all the files those have been added in ignore list through.

git update-index --assume-unchanged <file>

Try the below code:

$my_string = "'name', 'name2', 'name3',";
echo substr(trim($my_string), 0, -1);

Use this code to remove the last character of the string.

jQuery is just a set of helpers/libraries written in Javascript. You can still use all Javascript features, so you can call whatever functions, also from inside jQuery callbacks. So both possibilities should be okay.

I wrote the following code in one of my projects. It basically compares each individual element of the list. Feel free to use it, if it works for your requirement.

def reachedGoal(a,b):
    if(len(a)!=len(b)):
        raise ValueError("Wrong lists provided")

    for val1 in range(0,len(a)):
        temp1=a[val1]
        temp2=b[val1]
        for val2 in range(0,len(b)):
            if(temp1[val2]!=temp2[val2]):
                return False
    return True

java.time

We have new technology for this problem: the java.time framework built into Java 8 and later.

Your input string is in standard ISO 8601 format. That standard is used by default in the java.time classes for parsing/generating textual representations of date-time values.

OffsetDateTime odt = OffsetDateTime.parse( "2012-10-01T09:45:00.000+02:00" );

Your Question suggests you want to truncate to a whole second.

OffsetDateTime odtTruncatedToWholeSecond = odt.truncatedTo( ChronoUnit.SECONDS );

It seems you want to omit the offset and time zone info. The pre-defined formatter DateTimeFormatter.ISO_LOCAL_DATE_TIME does that.

And apparently you want to use a space in the middle rather than the standard T. You could define your own formatter for this, but I would just do a string manipulation to replace the T with a SPACE.

String output = odtTruncatedToWholeSecond.format( DateTimeFormatter.ISO_LOCAL_DATE_TIME ).replace( "T" , " " );

Simply String Manipulations

As the comments on the Question suggest, strictly speaking you can accomplish your goal by working only with strings and not converting to any date-time objects. But I provide this Answer here assuming you may have other business logic to work with these date-time values.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

I add aliases to the .bash_alaises to switch to a different project.

alias switch_proj1="gcloud config set project ************"

Here is a script to generate aliases :) for all projects listed. Please update the switch_proj to unique project aliases that you can remember.

gcloud projects list | awk '{print "alias switch_proj=\"gcloud config set project " $1 "\""}'

hopefully its work

SET foreign_key_checks = 0; DROP TABLE table name; SET foreign_key_checks = 1;

Your column "hundred" seems to be defined as primary key and therefore must be unique which is not the case. The problem isn't with, it is with your data.

I suggest you insert an id as serial type to handly the primary key

Solution for Pressing or handling back button in Fragment.

The way I solved my issue I am sure it will helps you too:

1.If you don't have any Edit Text-box in your fragment you can use below code

Here MainHomeFragment is main Fragment (When I press back button from second fragment it will take me too MainHomeFragment)

    @Override
    public void onResume() {

    super.onResume();

    getView().setFocusableInTouchMode(true);
    getView().requestFocus();
    getView().setOnKeyListener(new View.OnKeyListener() {
        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {

            if (event.getAction() == KeyEvent.ACTION_UP && keyCode == KeyEvent.KEYCODE_BACK){

                MainHomeFragment mainHomeFragment = new SupplierHomeFragment();
                android.support.v4.app.FragmentTransaction fragmentTransaction =
                        getActivity().getSupportFragmentManager().beginTransaction();
                fragmentTransaction.replace(R.id.fragment_container, mainHomeFragment);
                fragmentTransaction.commit();

                return true;    
            }    
            return false;
        }
    }); }

2.If you have another fragment named as Somefragment and it has Edit text-box then you can do it by this way.

private EditText editText;

Then In,

onCreateView():    
editText = (EditText) view.findViewById(R.id.editText);

Then Override OnResume,

@Override
public void onResume() {
    super.onResume();

    editText.setOnKeyListener(new View.OnKeyListener() {
        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            if (keyCode == KeyEvent.KEYCODE_BACK) {
                editTextOFS.clearFocus();
                getView().requestFocus();
            }
            return false;
        }
    });

    getView().setFocusableInTouchMode(true);
    getView().requestFocus();
    getView().setOnKeyListener(new View.OnKeyListener() {
        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {

            if (event.getAction() == KeyEvent.ACTION_UP && keyCode == KeyEvent.KEYCODE_BACK){

                MainHomeFragment mainHomeFragment = new SupplierHomeFragment();
                android.support.v4.app.FragmentTransaction fragmentTransaction =
                        getActivity().getSupportFragmentManager().beginTransaction();
                fragmentTransaction.replace(R.id.fragment_container, mainHomeFragment);
                fragmentTransaction.commit();

                return true;

            }

            return false;
        }
    });

}

That's all folks (amitamie.com) :-) ;-)

Instead of adding Reader("Name") you add a new ListItem. ListItem has a Text and a Value property that you can set.

I have another solution that makes this possible. It requires the client be running Javascript (which I think is a fair requirement these days).

Simply use an AJAX request on Page A to go and generate your invoice number and customer details in the background (your previous Page B), then once the request gets returned successfully with the correct information - simply complete the form submission over to your payment gateway (Page C).

This will achieve your result of the user only clicking one button and proceeding to the payment gateway. Below is some pseudocode

HTML:

<form id="paymentForm" method="post" action="https://example.com">
  <input type="hidden" id="customInvoiceId" .... />
  <input type="hidden" .... />

  <input type="submit" id="submitButton" />
</form>

JS (using jQuery for convenience but trivial to make pure Javascript):

$('#submitButton').click(function(e) {
  e.preventDefault(); //This will prevent form from submitting

  //Do some stuff like build a list of things being purchased and customer details

  $.getJSON('setupOrder.php', {listOfProducts: products, customerDetails: details }, function(data) {
  if (!data.error) {
    $('#paymentForm #customInvoiceID').val(data.id);
    $('#paymentForm').submit();   //Send client to the payment processor
  }
});

Swing vs AWT. Basically AWT came first and is a set of heavyweight UI components (meaning they are wrappers for operating system objects) whereas Swing built on top of AWT with a richer set of lightweight components.

Any serious Java UI work is done in Swing not AWT, which was primarily used for applets.

Best way to pass multiple complex object to webapi services is by using tuple other than dynamic, json string, custom class.

HttpClient.PostAsJsonAsync("http://Server/WebService/Controller/ServiceMethod?number=" + number + "&name" + name, Tuple.Create(args1, args2, args3, args4));

No need to serialize and deserialize passing object while using tuple. If you want to send more than seven complex object create internal tuple object for last tuple argument.

Okay, it was easy:

npm install webpack-dev-server -g

What confused me that I did not need that at first, probably things changed with a new version.

I was able to resolve this using the designer.

1. Open the Model Browser.
2. Find the view in the diagram.
3. Right click on the primary key, and make sure "Entity Key" is checked.
4. Multi-select all the non-primary keys. Use Ctrl or Shift keys.
5. In the Properties window (press F4 if needed to see it), change the "Entity Key" drop-down to False.
6. Save changes.
7. Close Visual Studio and re-open it. I am using Visual Studio 2013 with EF 6 and I had to do this to get the warnings to go away.

I did not have to change my view to use the ISNULL, NULLIF, or COALESCE workarounds. If you update your model from the database, the warnings will re-appear, but will go away if you close and re-open VS. The changes you made in the designer will be preserved and not affected by the refresh.

Depending on size and scale of the difficultly, you could create a scratch (temporary) branch and commit the current work there.

Then switch to and checkout your original branch, and pick the appropriate files from the scratch commit.

At least you would have a permanent record of the current and previous states to work from (until you delete that scratch branch).

For Pycharm CE 2018.3 and Ubuntu 18.04 with snap installation:

env BAMF_DESKTOP_FILE_HINT=/var/lib/snapd/desktop/applications/pycharm-community_pycharm-community.desktop /snap/bin/pycharm-community %f

I get this command from KDE desktop launch icon.

Sorry for the language but I am a Spanish developer so I have my system in Spanish.

From the Python glossary:

It’s important to keep in mind that all packages are modules, but not all modules are packages. Or put another way, packages are just a special kind of module. Specifically, any module that contains a __path__ attribute is considered a package.

Python files with a dash in the name, like my-file.py, cannot be imported with a simple import statement. Code-wise, import my-file is the same as import my - file which will raise an exception. Such files are better characterized as scripts whereas importable files are modules.

For anyone coming to this question wondering how to do this in Eclipse, You can remove the displayed text from the logCat using the button provided (often has a red X on the icon)

One additional hint to Pavel Perna's post which helped me very much (cannot comment with my reputation, that's why I post this as answer): In some versions of Microsoft Exchange, the inline contents disposition is removed (see this post by Microsoft). The image is simply not part in the mail the user sees in Outlook. As a workaround, use "Content-Disposition: attachement" instead. Outlook 2016 won't show images as attachement that are used in the mail message, although they use the "Content-Disposition: attachement".

public String stripNonValidXMLCharacters(String in) {
    StringBuffer out = new StringBuffer(); // Used to hold the output.
    char current; // Used to reference the current character.

    if (in == null || ("".equals(in))) return ""; // vacancy test.
    for (int i = 0; i < in.length(); i++) {
        current = in.charAt(i); // NOTE: No IndexOutOfBoundsException caught here; it should not happen.
        if ((current == 0x9) ||
            (current == 0xA) ||
            (current == 0xD) ||
            ((current >= 0x20) && (current <= 0xD7FF)) ||
            ((current >= 0xE000) && (current <= 0xFFFD)) ||
            ((current >= 0x10000) && (current <= 0x10FFFF)))
            out.append(current);
    }
    return out.toString();
}    

simply pass the argument

attachtoroot = false

View view = inflater.inflate(R.layout.child_layout_to_merge, parent_layout, false);

You can program defensively, and do your import as:

try:
    from urllib.request import urlopen
except ImportError:
    from urllib2 import urlopen

and then in the code, just use:

data = urlopen(MIRRORS).read(AMOUNT2READ)

Here what you can try:

var d = Date.parse("2016-07-19T20:23:01.804Z");
alert(d); //this is in milliseconds

There is no elegant way of getting the last element of a list in Java (compared to e.g. items[-1] in Python).

You have to use list.get(list.size()-1).

When working with lists obtained by complicated method calls, the workaround lies in temporary variable:

List<E> list = someObject.someMethod(someArgument, anotherObject.anotherMethod());
return list.get(list.size()-1);

This is the only option to avoid ugly and often expensive or even not working version:

return someObject.someMethod(someArgument, anotherObject.anotherMethod()).get(
    someObject.someMethod(someArgument, anotherObject.anotherMethod()).size() - 1
);

It would be nice if fix for this design flaw was introduced to Java API.

Had a similar problem, actually I ended up in probing the existence of some file within my web.

probePath would be the relative URL to the file you want to check for (kind of a marker if you're now at the correct location), e.g. 'assets/images/thisImageAlwaysExists.png'

<script type='text/javascript'>
  function configExists(url) {
    var req = new XMLHttpRequest();
    req.open('GET', url, false); 
    req.send();
    return req.status==200;
  }

  var probePath = '...(some file that must exist)...';
  var origin = document.location.origin;
  var pathSegments = document.location.pathname.split('/');

  var basePath = '/'
  var configFound = false;
  for (var i = 0; i < pathSegments.length; i++) {
    var segment = pathSegments[i];
    if (segment.length > 0) {
      basePath = basePath + segment + '/';
    }
    var fullPath = origin + basePath + probePath;
    configFound = configExists(fullPath);
    if (configFound) {
      break;
    }
  }

  document.write("<base href='" + (configFound ? basePath : '/') + "' />");
</script>

Depending on your needs, you can probably rely on node's path module.

You may not be able to hit the filesystem (e.g. the file hasn't been created yet) and tbh you probably want to avoid hitting the filesystem unless you really need the extra validation. If you can make the assumption that what you are checking for follows .<extname> format, just look at the name.

Obviously if you are looking for a file without an extname you will need to hit the filesystem to be sure. But keep it simple until you need more complicated.

const path = require('path');

function isFile(pathItem) {
  return !!path.extname(pathItem);
}

Is there a reason you are not doing something like:

public class IPGUI extends JFrame implements ActionListener 
{
    private static JPanel contentPane;

    private JButton btnConvertDocuments;
    private JButton btnExtractImages;
    private JButton btnParseRIDValues;
    private JButton btnParseImageInfo;

    public IPGUI() 
    {
        ...

        btnConvertDocuments = new JButton("1. Convert Documents");

        ...

        btnExtractImages = new JButton("2. Extract Images");

        ...

        //etc.
    }

    public void actionPerformed(ActionEvent event) 
    {
        String command = event.getActionCommand();

        if (command.equals("w"))
        {
            FileConverter fc = new FileConverter();
            btnConvertDocuments.setEnabled( false );
        }
        else if (command.equals("x"))
        {
            ImageExtractor ie = new ImageExtractor();
            btnExtractImages.setEnabled( false );
        }

        // etc.
    }    
}

The if statement with your disabling code won't get called unless you keep calling the IPGUI constructor.

Here's an alternative regular expression:

^(?=(.{4})*$)[A-Za-z0-9+/]*={0,2}$

It satisfies the following conditions:

• The string length must be a multiple of four - (?=^(.{4})*$)
• The content must be alphanumeric characters or + or / - [A-Za-z0-9+/]*
• It can have up to two padding (=) characters on the end - ={0,2}
• It accepts empty strings

I spent a lot of time trying different answers all around the internet, and I suspect the reasons why one thing works for some people and not for others is due to very small weird differences in application. For context, I needed to read in file names from a csv file that had strange and/or unmappable unicode characters and write them to a new csv file. For what it's worth, here's what worked for me:

s = '\u00e7\u00a3\u0085\u00e5\u008d\u0095' # csv freaks if you try to write this
s = repr(s.encode('utf-8', 'ignore'))[2:-1]

Here is a simple method.

Execute following commands.

This will enable your mod_rewrite module for Apache

$sudo a2enmod rewrite

This Command will change the owner of the folder to www-data

$sudo chown -R www-data [Wordpress Folder Location]

After You executing above commands you can install any themes without FTP.

1. Use the carousel's indicators to display thumbnails.
2. Position the thumbnails outside of the main carousel with CSS.
3. Set the maximum height of the indicators to not be larger than the thumbnails.
4. Whenever the carousel has slid, update the position of the indicators, positioning the active indicator in the middle of the indicators.

I'm using this on my site (for example here), but I'm using some extra stuff to do lazy loading, meaning extracting the code isn't as straightforward as I would like it to be for putting it in a fiddle.

Also, my templating engine is smarty, but I'm sure you get the idea.

The meat...

Updating the indicators:

<ol class="carousel-indicators">
    {assign var='walker' value=0}
    {foreach from=$item["imagearray"] key="key" item="value"}
        <li data-target="#myCarousel" data-slide-to="{$walker}"{if $walker == 0} class="active"{/if}>
            <img src='http://farm{$value["farm"]}.static.flickr.com/{$value["server"]}/{$value["id"]}_{$value["secret"]}_s.jpg'>
        </li>

        {assign var='walker' value=1 + $walker}
    {/foreach}
</ol>

Changing the CSS related to the indicators:

.carousel-indicators {
    bottom:-50px;
    height: 36px;
    overflow-x: hidden;
    white-space: nowrap;
}

.carousel-indicators li {
    text-indent: 0;
    width: 34px !important;
    height: 34px !important;
    border-radius: 0;
}

.carousel-indicators li img {
    width: 32px;
    height: 32px;
    opacity: 0.5;
}

.carousel-indicators li:hover img, .carousel-indicators li.active img {
    opacity: 1;
}

.carousel-indicators .active {
    border-color: #337ab7;
}

When the carousel has slid, update the list of thumbnails:

$('#myCarousel').on('slid.bs.carousel', function() {
    var widthEstimate = -1 * $(".carousel-indicators li:first").position().left + $(".carousel-indicators li:last").position().left + $(".carousel-indicators li:last").width(); 
    var newIndicatorPosition = $(".carousel-indicators li.active").position().left + $(".carousel-indicators li.active").width() / 2;
    var toScroll = newIndicatorPosition + indicatorPosition;
    var adjustedScroll = toScroll - ($(".carousel-indicators").width() / 2);
    if (adjustedScroll < 0)
        adjustedScroll = 0;

    if (adjustedScroll > widthEstimate - $(".carousel-indicators").width())
        adjustedScroll = widthEstimate - $(".carousel-indicators").width();

    $('.carousel-indicators').animate({ scrollLeft: adjustedScroll }, 800);

    indicatorPosition = adjustedScroll;
});

And, when your page loads, set the initial scroll position of the thumbnails:

var indicatorPosition = 0;

You must prepend an underscore to the css file to be included, and switch its extension to scss (ex: _yourfile.scss). Then you just have to call it this way:

@import "yourfile";

And it will include the contents of the file, instead of using the CSS standard @import directive.

If like me you have an array with dates formatted like YYYY[-MM[-DD]] where you'd like to order more specific dates before less specific ones, I came up with this handy function:

function sortByDateSpecificity(a, b) {
  const aLength = a.date.length
  const bLength = b.date.length
  const aDate = a.date + (aLength < 10 ? '-12-31'.slice(-10 + aLength) : '')
  const bDate = b.date + (bLength < 10 ? '-12-31'.slice(-10 + bLength) : '')
  return new Date(aDate) - new Date(bDate)
}

There is also some simple solution without mapping node_module directory into another volume. It's about to move installing npm packages into final CMD command.

Disadvantage of this approach:

• run npm install each time you run container (switching from npm to yarn might also speed up this process a bit).

worker/Dockerfile

FROM node:0.12
WORKDIR /worker
COPY package.json /worker/
COPY . /worker/
CMD /bin/bash -c 'npm install; npm start'

docker-compose.yml

redis:
    image: redis
worker:
    build: ./worker
    ports:
        - "9730:9730"
    volumes:
        - worker/:/worker/
    links:
        - redis

Have you tried this:

gitk path/to/file

What about?

    input[type="text"] {
          max-width:none;
   }

Checking that some css file is causing problems. By default bootstrap displays over the entire width. For instance in MVC directory Content is site.css and there is a definition constraining width.

input,select,textarea {
max-width: 280px;}

Try to use a grayscale colormap?

E.g. something like

imshow(..., cmap=pyplot.cm.binary)

For a list of colormaps, see http://scipy-cookbook.readthedocs.org/items/Matplotlib_Show_colormaps.html

i have the same problem from my office network. i use this command but its not working for me url, so like this: before $ git clone https://gitlab.com/omsharma/Resume.git

After i Use this URL : $ git clone https://[email protected]/omsharma/Resume.git try It.

The Maven Wrapper is an excellent choice for projects that need a specific version of Maven (or for users that don't want to install Maven at all). Instead of installing many versions of it in the operating system, we can just use the project-specific wrapper script.

mvnw: it's an executable Unix shell script used in place of a fully installed Maven

mvnw.cmd: it's for Windows environment

Use Cases

The wrapper should work with different operating systems such as:

• Linux
• OSX
• Windows
• Solaris

After that, we can run our goals like this for the Unix system:

./mvnw clean install

And the following command for Batch:

./mvnw.cmd clean install

If we don't have the specified Maven in the wrapper properties, it'll be downloaded and installed in the folder $USER_HOME/.m2/wrapper/dists of the system.

Maven Wrapper plugin

Maven Wrapper plugin to make auto installation in a simple Spring Boot project.

First, we need to go in the main folder of the project and run this command:

mvn -N io.takari:maven:wrapper

We can also specify the version of Maven:

mvn -N io.takari:maven:wrapper -Dmaven=3.5.2

The option -N means –non-recursive so that the wrapper will only be applied to the main project of the current directory, not in any submodules.

Source 1 (further reading): https://www.baeldung.com/maven-wrapper

It seems this is true but, personally, it seems to me to be poor design. Sure, have a default name (with extension) but allow other names and have a way of specifying the name of the docker file for commands.

Having an extension is also nice because it allows one to associate applications to that extension type. When I click on a Dockerfile in MacOSX it treats it as a Unix executable and tries to run it.

If Docker files had an extension I could tell the OS to start them with a particular application, e.g. my text editor application. I'm not sure but the current behaviour may also be related to the file permisssions.

To open from with button click please add the following code in the button event handler

var m = new Form1();
m.Show();

Here Form1 is the name of the form which you want to open.

Also to close the current form, you may use

this.close();

A simple for loop?

for i in range(3):
  do()

Or, if you're interested in the results and want to collect them, with the bonus of being a 1 liner:

vals = [do() for _ in range(3)]

What is a lambda function?

The C++ concept of a lambda function originates in the lambda calculus and functional programming. A lambda is an unnamed function that is useful (in actual programming, not theory) for short snippets of code that are impossible to reuse and are not worth naming.

In C++ a lambda function is defined like this

[]() { } // barebone lambda

or in all its glory

[]() mutable -> T { } // T is the return type, still lacking throw()

[] is the capture list, () the argument list and {} the function body.

The capture list

The capture list defines what from the outside of the lambda should be available inside the function body and how. It can be either:

1. a value: [x]
2. a reference [&x]
3. any variable currently in scope by reference [&]
4. same as 3, but by value [=]

You can mix any of the above in a comma separated list [x, &y].

The argument list

The argument list is the same as in any other C++ function.

The function body

The code that will be executed when the lambda is actually called.

Return type deduction

If a lambda has only one return statement, the return type can be omitted and has the implicit type of decltype(return_statement).

Mutable

If a lambda is marked mutable (e.g. []() mutable { }) it is allowed to mutate the values that have been captured by value.

Use cases

The library defined by the ISO standard benefits heavily from lambdas and raises the usability several bars as now users don't have to clutter their code with small functors in some accessible scope.

C++14

In C++14 lambdas have been extended by various proposals.

Initialized Lambda Captures

An element of the capture list can now be initialized with =. This allows renaming of variables and to capture by moving. An example taken from the standard:

int x = 4;
auto y = [&r = x, x = x+1]()->int {
            r += 2;
            return x+2;
         }();  // Updates ::x to 6, and initializes y to 7.

and one taken from Wikipedia showing how to capture with std::move:

auto ptr = std::make_unique<int>(10); // See below for std::make_unique
auto lambda = [ptr = std::move(ptr)] {return *ptr;};

Generic Lambdas

Lambdas can now be generic (auto would be equivalent to T here if T were a type template argument somewhere in the surrounding scope):

auto lambda = [](auto x, auto y) {return x + y;};

Improved Return Type Deduction

C++14 allows deduced return types for every function and does not restrict it to functions of the form return expression;. This is also extended to lambdas.

I found that with spring boot 2.0.2.RELEASE, configuring spring-boot-starter-data-jpa and com.h2database in the POM file is not just enough to have H2 console working. You must configure spring-boot-devtools as below. Optionally you could follow the instruction from Aaron Zeckoski in this post

  <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
        <optional>true</optional>
 </dependency>

Use GET when you want the URL to reflect the state of the page. This is useful for viewing dynamically generated pages, such as those seen here. A POST should be used in a form to submit data, like when I click the "Post Your Answer" button. It also produces a cleaner URL since it doesn't generate a parameter string after the path.

You can use Firephp an add-on to firebug to debug php in the same environment as javascript.

I also use Xdebug mentioned earlier for profiling php.

last 7 characters of a string:

$rest = substr( "abcdefghijklmnop", -7); // returns "jklmnop"

The elements of a sequence need to be indented at the same level. Assuming you want two jobs (A and B) each with an ordered list of key value pairs, you should use:

jobs:
 - - name: A
   - schedule: "0 0/5 * 1/1 * ? *"
   - - type: mongodb.cluster
     - config:
       - host: mongodb://localhost:27017/admin?replicaSet=rs
       - minSecondaries: 2
       - minOplogHours: 100
       - maxSecondaryDelay: 120
 - - name: B
   - schedule: "0 0/5 * 1/1 * ? *"
   - - type: mongodb.cluster
     - config:
       - host: mongodb://localhost:27017/admin?replicaSet=rs
       - minSecondaries: 2
       - minOplogHours: 100
       - maxSecondaryDelay: 120

Converting the sequences of (single entry) mappings to a mapping as @Tsyvarrev does is also possible, but makes you lose the ordering.

The .pid is the processid of the running mysql server instance. It appears in the data folder when mysql is running and removes itself when mysql is shutdown.

If the OSX operating system is upgraded and mysql is not shutdown properly before the upgrade,mysql quits when it started up it just quits because of the .pid file.

There are a few tricks you can try, http://coolestguidesontheplanet.com/mysql-error-server-quit-without-updating-pid-file/ failing these a reinstall is needed.

You might be loading multiselect.js file before the option list updated with AJAX call so while execution of multiselect.js file there is empty option list is there to apply multiselect functionlaity. So first update the option list by AJAX call then initiate the multiselect call you will get the dropdown list with the dynamic option list.

Hope this will help you out.

See if this answer can help you. Particularly the fact that CLI ini could be different than when the script is running through a browser.

Allowed memory size of X bytes exhausted

A quick-and-dirty way to debug small Node.js scripts with your favorite browser debugger would be to use browserify. Note that this approach doesn't work with any applications which require native I/O libraries, but it is good enough for most small scripts.

$ npm install -g browserify

Now move all your var x = requires('x') calls into a requires.js file and run:

$ browserify requires.js -s window -o bundle.js

(The downside here is that you either have to move or comment the requires in all your files.)

Include the bundle.js in an HTML file like so:

<script type="text/javascript" src="bundle.js"></script>

Now load the file in your browser and press F12 and viola: debug in browser.

Old Question, but still, if it might help someone, here is complete sample

        <asp:Button ID="Button1" runat="server" Text="Upload File" OnClick="UploadFile" /><br/>
        <asp:Label ID="Label1" runat="server" Text=""></asp:Label>
    </div>
</form>

In your Code-behind, C# code to grab file and save it in Directory

protected void UploadFile(object sender, EventArgs e)
    {
        //folder path to save uploaded file
        string folderPath = Server.MapPath("~/Upload/");

        //Check whether Directory (Folder) exists, although we have created, if it si not created this code will check
        if (!Directory.Exists(folderPath))
        {
            //If folder does not exists. Create it.
            Directory.CreateDirectory(folderPath);
        }

       //save file in the specified folder and path
        FileUpload1.SaveAs(folderPath + Path.GetFileName(FileUpload1.FileName));

        //once file is uploaded show message to user in label control
        Label1.Text = Path.GetFileName(FileUpload1.FileName) + " has been uploaded.";
    }

The problem is that an isin does not identify the exchange, only an issuer.

Let's say your isin is US4592001014 (IBM), one way to do it would be:

• get the ticker (in A1):

  =BDP("US4592001014 ISIN", "TICKER") => IBM
  

• get a proper symbol (in A2)

  =BDP("US4592001014 ISIN", "PARSEKYABLE_DES") => IBM XX Equity
  

  where XX depends on your terminal settings, which you can check on CNDF <Go>.

• get the main exchange composite ticker, or whatever suits your need (in A3):

  =BDP(A2,"EQY_PRIM_SECURITY_COMP_EXCH") => US
  

• and finally:

  =BDP(A1&" "&A3&" Equity", "LAST_PRICE") => the last price of IBM US Equity
  

I would aim at covering a subset of possible "Content-type" values, you question seems to focus on identifying known content types.

Since Ant 1.8.0 there's apparently also resourceexists

From http://ant.apache.org/manual/Tasks/conditions.html

Tests a resource for existance. since Ant 1.8.0

As of Ant 1.8.0, you may instead use property expansion; a value of true (or on or yes) will enable the item, while false (or off or no) will disable it. Other values are still assumed to be property names and so the item is enabled only if the named property is defined.

Compared to the older style, this gives you additional flexibility, because you can override the condition from the command line or parent scripts:

<target name="-check-use-file" unless="file.exists">
    <available property="file.exists" file="some-file"/>
</target>
<target name="use-file" depends="-check-use-file" if="${file.exists}">
    <!-- do something requiring that file... -->
</target>
<target name="lots-of-stuff" depends="use-file,other-unconditional-stuff"/>

from the ant manual at http://ant.apache.org/manual/properties.html#if+unless

Hopefully this example is of use to some. They're not using resourceexists, but presumably you could?.....

1. Like you installed older version of PHP do the same with Apache. I picked version 2.0.63 and then I was able to run WAMP Server with PHP 5.2.9 with no problems.

2. I also read that it's problem with 64-bit version of WAMP.

In Visual Studio 2017 Spanish version.

"Depurar" -> "Ventanas" -> "Configuración de Excepciones"

and search "ContextSwitchDeadlock". Then, uncheck it. Or shortcut

Ctrl+D,E

Best.

Here the converter for XStream including unmarshall

If you have already tried using the git add . command to add all your untracked files, make sure you're not under a subfolder of your root project.

git add . will stage all your files under the current subfolder.

As in a similar question, use display: inline-block with a placeholder element to vertically center the span inside of a block element:

html, body, #container, #placeholder { height: 100%; }_x000D_
_x000D_
#content, #placeholder { display:inline-block; vertical-align: middle; }

<!doctype html>_x000D_
<html lang="en">_x000D_
  <head>_x000D_
  </head>_x000D_
_x000D_
  <body>_x000D_
    <div id="container">_x000D_
      <span id="content">_x000D_
        Content_x000D_
      </span>_x000D_
      <span id="placeholder"></span>_x000D_
    </div>_x000D_
  </body>_x000D_
</html>

Vertical alignment is only applied to inline elements or table cells, so use it along with display:inline-block or display:table-cell with a display:table parent when vertically centering block elements.

I think this behavior can be turned off, but Window's online help wasn't extremely clear:

If you disable NetBIOS over TCP/IP, you cannot use broadcast-based NetBIOS name resolution to resolve computer names to IP addresses for computers on the same network segment. If your computers are on the same network segment, and NetBIOS over TCP/IP is disabled, you must install a DNS server and either have the computers register with DNS (or manually configure DNS records) or configure entries in the local Hosts file for each computer.

In Windows XP, there is a checkbox:

Advanced TCP/IP Settings

[ ] Enable LMHOSTS lookup

There is also a book that covers this at length, "Networking Personal Computers with TCP/IP: Building TCP/IP Networks (old O'Reilly book)". Unfortunately, I cannot look it up because I disposed of my copy a while ago.

Modern way:

newParent.append(...oldParent.childNodes);

1. .append is the replacement for .appendChild. The main difference is that it accepts multiple nodes at once and even plain strings, like .append('hello!')
2. oldParent.childNodes is iterable so it can be spread with ... to become multiple parameters of .append()

Compatibility tables of both (in short: Edge 17+, Safari 10+):

The amount of hacks you would need to go through to completely hide the fact your site is built by Meteor.js is absolutely ridiculous. You would have to strip essentially all core functionality and just serve straight up html, completely defeating the purpose of using the framework anyway.

That being said, I suggest looking at buildwith.com

You enter a url, and it reveals a ton of information about a site. If you only need to "fool" engines like this, there may be simple solutions.

In some cases check permissions (ownership).

GitLab's "merge request" feature is equivalent to GitHub's "pull request" feature. Both are means of pulling changes from another branch or fork into your branch and merging the changes with your existing code. They are useful tools for code review and change management.

An article from GitLab discusses the differences in naming the feature:

Merge or pull requests are created in a git management application and ask an assigned person to merge two branches. Tools such as GitHub and Bitbucket choose the name pull request since the first manual action would be to pull the feature branch. Tools such as GitLab and Gitorious choose the name merge request since that is the final action that is requested of the assignee. In this article we'll refer to them as merge requests.

A "merge request" should not be confused with the git merge command. Neither should a "pull request" be confused with the git pull command. Both git commands are used behind the scenes in both pull requests and merge requests, but a merge/pull request refers to a much broader topic than just these two commands.

Just as @Nic Hubbard said, there is a very easy way to add a border line.

<View
    android:layout_width="match_parent"
    android:layout_height="2dp"
    android:background="#000000" >
</View>

You can change the height and background color to whatever you want.

use parseInt

   var total = parseInt(a) + parseInt(b);


    $('#total_price').val(total);

Call the pd.DataFrame constructor directly:

df = pd.DataFrame(table, columns=headers)
df

   Heading1  Heading2
0         1         2
1         3         4

Using Tyler Dodge's excellent answer kept lagging on my iPad, so I added some throttling code, now it's quite smooth. There is some minimal skipping sometimes while scrolling.

// Uses document because document will be topmost level in bubbling
$(document).on('touchmove',function(e){
  e.preventDefault();
});

var scrolling = false;

// Uses body because jquery on events are called off of the element they are
// added to, so bubbling would not work if we used document instead.
$('body').on('touchstart','.scrollable',function(e) {

    // Only execute the below code once at a time
    if (!scrolling) {
        scrolling = true;   
        if (e.currentTarget.scrollTop === 0) {
          e.currentTarget.scrollTop = 1;
        } else if (e.currentTarget.scrollHeight === e.currentTarget.scrollTop + e.currentTarget.offsetHeight) {
          e.currentTarget.scrollTop -= 1;
        }
        scrolling = false;
    }
});

// Prevents preventDefault from being called on document if it sees a scrollable div
$('body').on('touchmove','.scrollable',function(e) {
  e.stopPropagation();
});

Also, adding the following CSS fixes some rendering glitches (source):

.scrollable {
    overflow: auto;
    overflow-x: hidden;
    -webkit-overflow-scrolling: touch;
}
.scrollable * {
    -webkit-transform: translate3d(0,0,0);
}

Just add position, right and top to your class .close-image

.close-image {
    cursor: pointer;
    display: block;
    float: right;  
    z-index: 3;
    position: absolute; /*newly added*/
    right: 5px; /*newly added*/
    top: 5px;/*newly added*/
}

You can also use Bash on Ubuntu on Windows directly. E.g.,

bash -c "ssh -t user@computer 'cd /; sudo my-command'"

Per Martin Prikryl's comment below:

The -t enables terminal emulation. Whether you need the terminal emulation for sudo depends on configuration (and by default you do no need it, while many distributions override the default). On the contrary, many other commands need terminal emulation.

Much like leonardocsouza, I had the same problem. To clarify a bit, this is what my folder structure looked like when I ran node server.js

node_modules/
app/
  index.html
  server.js

After printing out the __dirname path, I realized that the __dirname path was where my server was running (app/).

So, the answer to your question is this:

If your server.js file is in the same folder as the files you are trying to render, then

app.use( express.static( path.join( application_root, 'site') ) );

should actually be

app.use(express.static(application_root));

The only time you would want to use the original syntax that you had would be if you had a folder tree like so:

app/
  index.html
node_modules
server.js

where index.html is in the app/ directory, whereas server.js is in the root directory (i.e. the same level as the app/ directory).

Side note: Intead of calling the path utility, you can use the syntax application_root + 'site' to join a path.

Overall, your code could look like:

// Module dependencies.
var application_root = __dirname,
express = require( 'express' ), //Web framework
mongoose = require( 'mongoose' ); //MongoDB integration

//Create server
var app = express();

// Configure server
app.configure( function() {

    //Don't change anything here...

    //Where to serve static content
    app.use( express.static( application_root ) );

    //Nothing changes here either...
});

//Start server --- No changes made here
var port = 5000;
app.listen( port, function() {
    console.log( 'Express server listening on port %d in %s mode', port, app.settings.env );
});

Yes, if bar is not None is more explicit, and thus better, assuming it is indeed what you want. That's not always the case, there are subtle differences: if not bar: will execute if bar is any kind of zero or empty container, or False. Many people do use not bar where they really do mean bar is not None.

r-squared: You can return the r-squared value directly from the summary object summary(fit)$r.squared. See names(summary(fit)) for a list of all the items you can extract directly.

Model p-value: If you want to obtain the p-value of the overall regression model, this blog post outlines a function to return the p-value:

lmp <- function (modelobject) {
    if (class(modelobject) != "lm") stop("Not an object of class 'lm' ")
    f <- summary(modelobject)$fstatistic
    p <- pf(f[1],f[2],f[3],lower.tail=F)
    attributes(p) <- NULL
    return(p)
}

> lmp(fit)
[1] 1.622665e-05

In the case of a simple regression with one predictor, the model p-value and the p-value for the coefficient will be the same.

Coefficient p-values: If you have more than one predictor, then the above will return the model p-value, and the p-value for coefficients can be extracted using:

summary(fit)$coefficients[,4]  

Alternatively, you can grab the p-value of coefficients from the anova(fit) object in a similar fashion to the summary object above.

Remove [selected] from option tag:

<option *ngFor="let opt of question.options" [value]="opt.key">
  {{opt.selected+opt.value}}
</option>

And in your form builder add:

key: this.question.options.filter(val => val.selected === true).map(data => data.key)

You can use a join to do this

SELECT t1.* from myTable t1
LEFT OUTER JOIN myTable t2 on t2.ID=t1.ID AND t2.`Date` > t1.`Date`
WHERE t2.`Date` IS NULL;

Only rows which have the latest date for each ID with have a NULL join to t2.

The urls are different.

• http://localhost/AccountSvc/DataInquiry.asmx

vs.

• /acctinqsvc/portfolioinquiry.asmx

Resolve this issue first, as if the web server cannot resolve the URL you are attempting to POST to, you won't even begin to process the actions described by your request.

You should only need to create the WebRequest to the ASMX root URL, ie: http://localhost/AccountSvc/DataInquiry.asmx, and specify the desired method/operation in the SOAPAction header.

The SOAPAction header values are different.

• http://localhost/AccountSvc/DataInquiry.asmx/ + methodName

vs.

• http://tempuri.org/GetMyName

You should be able to determine the correct SOAPAction by going to the correct ASMX URL and appending ?wsdl

There should be a <soap:operation> tag underneath the <wsdl:operation> tag that matches the operation you are attempting to execute, which appears to be GetMyName.

There is no XML declaration in the request body that includes your SOAP XML.

You specify text/xml in the ContentType of your HttpRequest and no charset. Perhaps these default to us-ascii, but there's no telling if you aren't specifying them!

The SoapUI created XML includes an XML declaration that specifies an encoding of utf-8, which also matches the Content-Type provided to the HTTP request which is: text/xml; charset=utf-8

Hope that helps!

Try wrapping the spans in an anchor tag and apply the background image to that.

HTML:

<div class="header">
    <a href="/">
        <span class="header-title">My gray sea design</span><br />
        <span class="header-title-two">A beautiful design</span>
    </a>
</div>

CSS:

.header {
    border-bottom:1px solid #eaeaea;
}

.header a {
    display: block;
    background-image: url("./images/embouchure.jpg");
    background-repeat: no-repeat;
    height:160px;
    padding-left:280px;
    padding-top:50px;
    width:470px;
    color: #eaeaea;
}

The reason must be somewhere else. Using only Spring Boot 1.2.2 out of the box with no configuration, it Just Works. Have a look at this repo - can you get it to break?

https://github.com/konrad-garus/so-yaml

Are you sure the YAML file looks exactly the way you pasted? No extra whitespace, characters, special characters, mis-indentation or something of that sort? Is it possible you have another file elsewhere in the search path that is used instead of the one you're expecting?

You can resolve this issue with php.

$mydate = strtotime($startdate);
$newformat = date('d-m-Y',$mydate);
echo '<tr>';
echo '  <td data-sort="'. $mydate .'">'.$newformat .'</td>';

MaxLengthAttribute is working since MVC 5.1 update: change notes

The newline character is actually '\n'.

Following two options worked for me:

1) A function that returns the number of rows in your ResultSet.

private int resultSetCount(ResultSet resultSet) throws SQLException{
    try{
        int i = 0;
        while (resultSet.next()) {
            i++;
        }
        return i;
    } catch (Exception e){
       System.out.println("Error getting row count");
       e.printStackTrace();
    }
    return 0;
}

2) Create a second SQL statement with the COUNT option.

You can use $("#drpList").val();

I understand this post is old but if anybody is still searching and has not found a solution to the intellisense issue even after re-installing, applying the cumulative updates, or other methods, then I hope I may be of assistance.

I have Applied SQL 2008 R2 Service Pack 1 which you can download here

http://www.microsoft.com/download/en/details.aspx?id=26727

32 Bit: SQLServer2008R2SP1-KB2528583-x86-ENU.exe

64 Bit: SQLServer2008R2SP1-KB2528583-x64-ENU.exe

I have applied this SP1 and now my intellisense works again. I hope this helps! (:

you can declare a Numpy array dynamically for 1 dimension as shown below:

import numpy as np

n = 2
new_table = np.empty(shape=[n,1])

new_table[0,0] = 2
new_table[1,0] = 3
print(new_table)

The above example assumes we know we need to have 1 column but we want to allocate the number of rows dynamically (in this case the number or rows required is equal to 2)

output is shown below:

[[2.] [3.]]
