I figured out myself.

cmp calls ComputeBetasAndNuHat which returns a list which has objective as minusloglik

So I can change the function cmp to get this value.

You should not use your domain models in your views. ViewModels are the correct way to do it.

You need to map your domain model's necessary fields to viewmodel and then use this viewmodel in your controllers. This way you will have the necessery abstraction in your application.

If you never heard of viewmodels, take a look at this.

In your last block you have a comma after 'lang', followed immediately with a function. This is not valid json.

EDIT

It appears that the readme was incorrect. I had to to pass an array with the string 'twitter'.

var converter = new Showdown.converter({extensions: ['twitter']}); converter.makeHtml('whatever @meandave2020'); // output "<p>whatever <a href="http://twitter.com/meandave2020">@meandave2020</a></p>" 

I submitted a pull request to update this.

Are you using php 5.4 on your local? the render line is using the new way of initializing arrays. Try replacing ["title" => "Welcome "] with array("title" => "Welcome ")

Problems only surface when I am I trying to give the first loaded content an active state

Does this mean that you want to add a class to the first button?

$('.o-links').click(function(e) {   // ... }).first().addClass('O_Nav_Current'); 

instead of using IDs for the slider's items and resetting html contents you can use classes and indexes:

CSS:

.image-area {     width: 100%;     height: auto;     display: none; }  .image-area:first-of-type {     display: block; } 

JavaScript:

var $slides = $('.image-area'),     $btns = $('a.o-links');  $btns.on('click', function (e) {     var i = $btns.removeClass('O_Nav_Current').index(this);     $(this).addClass('O_Nav_Current');      $slides.filter(':visible').fadeOut(1000, function () {         $slides.eq(i).fadeIn(1000);     });      e.preventDefault();  }).first().addClass('O_Nav_Current');

1. What exactly doesn't work?
2. Why are you using a 2d array?

3. If you must use a 2d array:

   int numOfPairs = 10;  String[][] array = new String[numOfPairs][2]; for(int i = 0; i < array.length; i++){     for(int j = 0; j < array[i].length; j++){         array[i] = new String[2];         array[i][0] = "original word";         array[i][1] = "rearranged word";     }    } 

Does this give you a hint?

Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

Javascript which runs on the client machine can't access the local disk file system due to security restrictions.

If you want to access the client's disk file system then look into an embedded client application which you serve up from your webpage, like an Applet, Silverlight or something like that. If you like to access the server's disk file system, then look for the solution in the server side corner using a server side programming language like Java, PHP, etc, whatever your webserver is currently using/supporting.

First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.

Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.

Instead, I would move all of the "application" content to a separate component, like a JPanel for example and simply move this between the applet or frame as required...

ps- You can use f.setLocationRelativeTo(null) to center the window on the screen ;)

Updated

You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...

Within the constructor of GalzyTable2 you are doing...

JApplet app = new JApplet(); add(app); app.init(); app.start(); 

...Why are you adding another applet to an applet??

Case in point...

Within the main method, you are trying to add the instance of JFrame to itself...

f.getContentPane().add(f, button2); 

Instead, create yourself a class that extends from something like JPanel, add your UI logical to this, using compound components if required.

Then, add this panel to whatever top level container you need.

You also seem to have a lack of understanding about how to use layout managers.

The primary flag seems to only work for vagrant ssh for me.

In the past I have used the following method to hack around the issue.

# stage box intended for configuration closely matching production if ARGV[1] == 'stage'     config.vm.define "stage" do |stage|         box_setup stage, \         "10.9.8.31", "deploy/playbook_full_stack.yml", "deploy/hosts/vagrant_stage.yml"     end end 

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.

From the docs:

_trackTrans() Sends both the transaction and item data to the Google Analytics server. This method should be called after _trackPageview(), and used in conjunction with the _addItem() and addTrans() methods. It should be called after items and transaction elements have been set up.

So, according to the docs, the items get sent when you call trackTrans(). Until you do, you can add items, but the transaction will not be sent.

Edit: Further reading led me here:

http://www.analyticsmarket.com/blog/edit-ecommerce-data

Where it clearly says you can start another transaction with an existing ID. When you commit it, the new items you listed will be added to that transaction.

I got this error when I made the bonehead mistake of importing MatSnackBar instead of MatSnackBarModule in app.module.ts.

It's really simple to fix the issue, however keep in mind that you should fork and commit your changes for each library you are using in their repositories to help others as well.

Let's say you have something like this in your code:

$str = "test";
echo($str{0});

since PHP 7.4 curly braces method to get individual characters inside a string has been deprecated, so change the above syntax into this:

$str = "test";
echo($str[0]);

Fixing the code in the question will look something like this:

public function getRecordID(string $zoneID, string $type = '', string $name = ''): string
{
    $records = $this->listRecords($zoneID, $type, $name);
    if (isset($records->result[0]->id)) {
        return $records->result[0]->id;
    }
    return false;
}

Recently have the issue. The fix which work for me was to added this to babel.config.json in the plugins section

["@babel/plugin-transform-modules-commonjs", {
    "allowTopLevelThis": true,
    "loose": true,
    "lazy": true
  }],

I had some imported module with // and the error "cannot use import outside a module".

This happened to me when I registered a new domain name, e.g., "new" for example.com (new.example.com). The name could not be resolved temporarily in my location for a couple of hours, while it could be resolved abroad. So I used a proxy to test the website where I saw net::ERR_HTTP2_PROTOCOL_ERROR in chrome console for some AJAX posts. Hours later, when the name could be resloved locally, those error just dissappeared.

I think the reason for that error is those AJAX requests were not redirected by my proxy, it just visit a website which had not been resolved by my local DNS resolver.

For me, it was caused before I referred a library (specifically typeORM, using the ormconfig.js file, under the entities key) to the src folder, instead of the dist folder...

   "entities": [
      "src/db/entity/**/*.ts", // Pay attention to "src" and "ts" (this is wrong)
   ],

instead of

   "entities": [
      "dist/db/entity/**/*.js", // Pay attention to "dist" and "js" (this is the correct way)
   ],

This is caused by node v12.11.0 due to the way it deals regular location there two ways to solve this problem

Method I

You can downgrade to node v12.10.0 this will apply the correct way to deal with parsing error

Method II

You can correctly terminate the regular expression in you case by changing the file located a:

\node_modules\metro-config\src\defaults\blacklist.js

From:

var sharedBlacklist = [
  /node_modules[/\\]react[/\\]dist[/\\].*/,
  /website\/node_modules\/.*/,
  /heapCapture\/bundle\.js/,
  /.*\/__tests__\/.*/
];

To:

 var sharedBlacklist = [
  /node_modules[\/\\]react[\/\\]dist[\/\\].*/,
  /website\/node_modules\/.*/,
  /heapCapture\/bundle\.js/,
  /.*\/__tests__\/.*/
];

This one worked for me (it seems like they changed the button classname or id) :

function ClickConnect(){_x000D_
    console.log("Working"); _x000D_
    document.querySelector("colab-connect-button").click() _x000D_
}_x000D_
setInterval(ClickConnect,60000)

What we ended up doing is stopped using the class components and created Functional Components, using useEffect() from the Hooks API for lifecycle methods. This allows you to still use makeStyles() with Lifecycle Methods without adding the complication of making Higher-Order Components. Which is much simpler.

Example:

import React, { useEffect, useState } from 'react';
import axios from 'axios';
import { Redirect } from 'react-router-dom';

import { Container, makeStyles } from '@material-ui/core';

import LogoButtonCard from '../molecules/Cards/LogoButtonCard';

const useStyles = makeStyles(theme => ({
  root: {
    display: 'flex',
    alignItems: 'center',
    justifyContent: 'center',
    margin: theme.spacing(1)
  },
  highlight: {
    backgroundColor: 'red',
  }
}));

// Highlight is a bool
const Welcome = ({highlight}) => { 
  const [userName, setUserName] = useState('');
  const [isAuthenticated, setIsAuthenticated] = useState(true);
  const classes = useStyles();

  useEffect(() => {
    axios.get('example.com/api/username/12')
         .then(res => setUserName(res.userName));
  }, []);

  if (!isAuthenticated()) {
    return <Redirect to="/" />;
  }
  return (
    <Container maxWidth={false} className={highlight ? classes.highlight : classes.root}>
      <LogoButtonCard
        buttonText="Enter"
        headerText={isAuthenticated && `Welcome, ${userName}`}
        buttonAction={login}
      />
   </Container>
   );
  }
}

export default Welcome;

on jupyter notebook using

np_load_old = np.load

# modify the default parameters of np.load
np.load = lambda *a,**k: np_load_old(*a, allow_pickle=True, **k)

worked fine, but the problem appears when you use this method in spyder(you have to restart the kernel every time or you will get an error like:

TypeError : () got multiple values for keyword argument 'allow_pickle'

I solved this issue using the solution here:

Just change "target": "es2015" to "target": "es5" in your tsconfig.json.

With the release of TypeScript 3.7, optional chaining (the ? operator) is now officially available.

As such, you can simplify your expression to the following:

const data = change?.after?.data();

You may read more about it from that version's release notes, which cover other interesting features released on that version.

Run the following to install the latest stable release of TypeScript.

npm install typescript

That being said, Optional Chaining can be used alongside Nullish Coalescing to provide a fallback value when dealing with null or undefined values

const data = change?.after?.data() ?? someOtherData();

I tried many solutions but didn't work for me. The below solution works for me.

I am on Windows 10, I had the problem with a new fresh installation of Anaconda on python 3.7.4, this post on github solved my problem:

( source: https://github.com/conda/conda/issues/8273)

I cite:

" My workaround: I have copied the following files

libcrypto-1_1-x64.*
libssl-1_1-x64.*

from D:\Anaconda3\Library\bin to D:\Anaconda3\DLLs.

And it works as a charm! "

Open angular.json file and find budgets keyword.

It should look like:

    "budgets": [
       {
          "type": "initial",
          "maximumWarning": "2mb",
          "maximumError": "5mb"
       }
    ]

As you’ve probably guessed you can increase the maximumWarning value to prevent this warning, i.e.:

    "budgets": [
       {
          "type": "initial",
          "maximumWarning": "4mb", <===
          "maximumError": "5mb"
       }
    ]

What does budgets mean?

A performance budget is a group of limits to certain values that affect site performance, that may not be exceeded in the design and development of any web project.

In our case budget is the limit for bundle sizes.

See also:

• https://github.com/webpack/webpack/issues/3216
• https://angular.io/guide/build#configure-size-budgets
• Performance Budgets (Keep Request Counts Low And File Sizes Small)

The solution from @ford04 didn't worked to me and specially if you need to use the isMounted in multiple places (multiple useEffect for instance), it's recommended to useRef, as bellow:

1. Essential packages

"dependencies": 
{
  "react": "17.0.1",
}
"devDependencies": { 
  "typescript": "4.1.5",
}

2. My Hook Component

export const SubscriptionsView: React.FC = () => {
  const [data, setData] = useState<Subscription[]>();
  const isMounted = React.useRef(true);

  React.useEffect(() => {
    if (isMounted.current) {
      // fetch data
      // setData (fetch result)

      return () => {
        isMounted.current = false;
      };
    }
  }
});

.catch(error => { throw error}) is a no-op. It results in unhandled rejection in route handler.

As explained in this answer, Express doesn't support promises, all rejections should be handled manually:

router.get("/emailfetch", authCheck, async (req, res, next) => {
  try {
  //listing messages in users mailbox 
    let emailFetch = await gmaiLHelper.getEmails(req.user._doc.profile_id , '/messages', req.user.accessToken)
    emailFetch = emailFetch.data
    res.send(emailFetch)
  } catch (err) {
    next(err);
  }
})

axios signature for post is axios.post(url[, data[, config]]). So you want to send params object within the third argument:

.post(`/mails/users/sendVerificationMail`, null, { params: {
  mail,
  firstname
}})
.then(response => response.status)
.catch(err => console.warn(err));

This will POST an empty body with the two query params:

POST http://localhost:8000/api/mails/users/sendVerificationMail?mail=lol%40lol.com&firstname=myFirstName

Angular and Django Rest Framework.

I encountered similar error while making post request to my DRF api. It happened that all I was missing was trailing slash for endpoint.

To make an exact spacing, I use Padding. An example with two images:

Row(
    mainAxisAlignment: MainAxisAlignment.spaceAround,
    children: <Widget>[
      Expanded(
        child: Padding(
          padding: const EdgeInsets.all(16.0),
          child: Image.asset('images/user1.png'),
        ),
      ),
      Expanded(
        child: Padding(
          padding: const EdgeInsets.all(16.0),
          child: Image.asset('images/user2.png'),
        ),
      )
    ],
  ),

You can add some code like this

ListView.builder{
   shrinkWrap: true,
}

There are many answers here but I will put here the most important one which everyone should use.

1. Column

 Column(
          children: <Widget>[
            Text('Widget A'), //Can be any widget
            SizedBox(height: 20,), //height is space betweeen your top and bottom widget
            Text('Widget B'), //Can be any widget
          ],
        ),

2. Wrap

     Wrap(
          direction: Axis.vertical, // We have to declare Axis.vertical, otherwise by default widget are drawn in horizontal order
            spacing: 20, // Add spacing one time which is same for all other widgets in the children list
            children: <Widget>[
              Text('Widget A'), // Can be any widget
              Text('Widget B'), // Can be any widget
            ]
        )

According to the release-notes, Java 11 removed the Java EE modules:

java.xml.bind (JAXB) - REMOVED

• Java 8 - OK
• Java 9 - DEPRECATED
• Java 10 - DEPRECATED
• Java 11 - REMOVED

See JEP 320 for more info.

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.0</version>
</dependency>

Jakarta EE 8 update (Mar 2020)

Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>2.3.3</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.3</version>
  <scope>runtime</scope>
</dependency>

Jakarta EE 9 update (Nov 2020)

Use latest release of Eclipse Implementation of JAXB 3.0.0:

• Jakarta EE9 API jakarta.xml.bind-api
• compatible implementation jaxb-impl

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>3.0.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>3.0.0</version>
  <scope>runtime</scope>
</dependency>

Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*, so update import statements:

javax.xml.bind -> jakarta.xml.bind

If some one working on monorepo following react-native-web-monorepo than you need to config-overrides.js file in packages/web. you need to add resolveApp('../../node_modules/react-native-ratings'), in that file...

The reason for this error occurs is that you are using the CryptoListPresenter _presenter without initializing.

I found that CryptoListPresenter _presenter would have to be initialized to fix because _presenter.loadCurrencies() is passing through a null variable at the time of instantiation;

there are two ways to initialize

1. Can be initialized during an declaration, like this

   CryptoListPresenter _presenter = CryptoListPresenter();
   

2. In the second, initializing(with assigning some value) it when initState is called, which the framework will call this method once for each state object.

   @override
   void initState() {
     _presenter = CryptoListPresenter(...);
   }
   

You can use this one and it's best practice.

SingleChildScrollView(
  child: Column(
    children: <Widget>[
      //Your Widgets
      //Your Widgets,
      //Your Widgets
    ],
  ),
);

The key is to use "Content-Type": "text/plain" as mentioned by @MadhuBhat.

axios.post(path, code, { headers: { "Content-Type": "text/plain" } }).then(response => {
    console.log(response);
});

A thing to note if you use .NET is that a raw string to a controller will return 415 Unsupported Media Type. To get around this you need to encapsulate the raw string in hyphens like this and send it as "Content-Type": "application/json":

axios.post(path, "\"" + code + "\"", { headers: { "Content-Type": "application/json" } }).then(response => {
    console.log(response);
});

C# Controller:

[HttpPost]
public async Task<ActionResult<string>> Post([FromBody] string code)
{
    return Ok(code);
}

https://weblog.west-wind.com/posts/2017/sep/14/accepting-raw-request-body-content-in-aspnet-core-api-controllers

You can also make a POST with query params if that helps:

.post(`/mails/users/sendVerificationMail`, null, { params: {
  mail,
  firstname
}})
.then(response => response.status)
.catch(err => console.warn(err));

This will POST an empty body with the two query params:

POST http://localhost:8000/api/mails/users/sendVerificationMail?mail=lol%40lol.com&firstname=myFirstName

Source: https://stackoverflow.com/a/53501339/3850405

You are calling:

JSON.parse(scatterSeries)

But when you defined scatterSeries, you said:

var scatterSeries = []; 

When you try to parse it as JSON it is converted to a string (""), which is empty, so you reach the end of the string before having any of the possible content of a JSON text.

scatterSeries is not JSON. Do not try to parse it as JSON.

data is not JSON either (getJSON will parse it as JSON automatically).

ch is JSON … but shouldn't be. You should just create a plain object in the first place:

var ch = {
    "name": "graphe1",
    "items": data.results[1]
};

scatterSeries.push(ch);

In short, for what you are doing, you shouldn't have JSON.parse anywhere in your code. The only place it should be is in the jQuery library itself.

Try replacing your last line of gulpfile.js

gulp.task('default', ['server', 'watch']);

with

gulp.task('default', gulp.series('server', 'watch'));

Actually, axios.delete supports a request body.
It accepts two parameters: a URL and an optional config. That is...

axios.delete(url: string, config?: AxiosRequestConfig | undefined)

You can do the following to set the response body for the delete request:

let config = { 
    headers: {
        Authorization: authToken
    },
    data: { //! Take note of the `data` keyword. This is the request body.
        key: value,
        ... //! more `key: value` pairs as desired.
    } 
}

axios.delete(url, config)

I hope this helps someone!

I had got the same CORS error while working on a Vue.js project. You can resolve this either by building a proxy server or another way would be to disable the security settings of your browser (eg, CHROME) for accessing cross origin apis (this is temporary solution & not the best way to solve the issue). Both these solutions had worked for me. The later solution does not require any mock server or a proxy server to be build. Both these solutions can be resolved at the front end.

You can disable the chrome security settings for accessing apis out of the origin by typing the below command on the terminal:

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --user-data-dir="/tmp/chrome_dev_session" --disable-web-security

After running the above command on your terminal, a new chrome window with security settings disabled will open up. Now, run your program (npm run serve / npm run dev) again and this time you will not get any CORS error and would be able to GET request using axios.

Hope this helps!

I think the error is caused by the redundant ,

flutter:
  uses-material-design: true, # <<< redundant , at the end of the line
  assets:
    - images/lake.jpg

I'd also suggest to create an assets folder in the directory that contains the pubspec.yaml file and move images there and use

flutter:
  uses-material-design: true
  assets:
    - assets/images/lake.jpg

The assets directory will get some additional IDE support that you won't have if you put assets somewhere else.

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();

In most cases, the blocked response should not affect the web page's behavior and the CORB error message can be safely ignored. For example, the warning may occur in cases when the body of the blocked response was empty already, or when the response was going to be delivered to a context that can't handle it (e.g., a HTML document such as a 404 error page being delivered to an tag).

https://www.chromium.org/Home/chromium-security/corb-for-developers

I had to clean my browser's cache, I was reading in this link, that, if the request get a empty response, we get this warning error. I was getting some CORS on my request, and so the response of this request got empty, All I had to do was clear the browser's cache, and the CORS got away. I was receiving CORS because the chrome had saved the PORT number on the cache, The server would just accept localhost:3010 and I was doing localhost:3002, because of the cache.

The Problem is the Container that gets the smallest possible size.

Just give a width: to the Container (in red) and you are done.

width: MediaQuery.of(context).size.width

  new Positioned(
  bottom: 0.0,
  child: new Container(
    width: MediaQuery.of(context).size.width,
    color: Colors.red,
    margin: const EdgeInsets.all(0.0),
    child: new Column(
      mainAxisAlignment: MainAxisAlignment.center,
      children: <Widget>[
        new Align(
          alignment: Alignment.bottomCenter,
          child: new ButtonBar(
            alignment: MainAxisAlignment.center,
            children: <Widget>[
              new OutlineButton(
                onPressed: null,
                child: new Text(
                  "Login",
                  style: new TextStyle(color: Colors.white),
                ),
              ),
              new RaisedButton(
                color: Colors.white,
                onPressed: null,
                child: new Text(
                  "Register",
                  style: new TextStyle(color: Colors.black),
                ),
              )
            ],
          ),
        )
      ],
    ),
  ),
),

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]))

                                                       .append(placement_by_video_summary_new, sort=True)
                                                       .sort_index()

using command

npm install bootstrap --save

open .angular.json old (.angular-cli.json ) file find the "styles" add the bootstrap css file

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

This works!

  var body = json.encode(data);

  var response = await http.post(url,
      headers: {"Content-Type": "application/json"},

  print("${response.statusCode}");
  print("${response.body}");
  return response;
}

This worked for me:

mysql> FLUSH PRIVILEGES 
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES

if u wanna use async await try

export const post = async ( link,data ) => {
const option = {

    validateStatus: function (status) {
        return status >= 200 && status < 300; // default

    data
};

try {
    const response = await axios(option);
} catch (error) {
    const { response } = error;
    const { request, ...errorObject } = response; // take everything but 'request'
    console.log(errorObject);
}

This line provided on GitHub issue community fixed my problem, here it is just in case it helps anyone else.

@rem Execute sdkmanager

My approach to the problem is similar to the way datayeah did it. I had a lot of hardcoded width and height values and the app looked fine on a specific device. So I got the screen height of the device and just created a factor to scale the hardcoded values.

double heightFactor = MediaQuery.of(context).size.height/708

where 708 is the height of the specific device.

I had this problem suddenly happening after trying to pull a dependency depending on sdk 28 (firebase crashlytics), but then decided to revert back the changes.

I tried automatic refactor Migrate to Androidx (which do half the job), added android.useAndroidX=true in gradle.properties at some points, and make the project work again.

But it was a lot of changes before a delivery. There was no way to have the project compile again with SDK 27. I git clean -fd, removed $HOME/.gradle, and kept seeing androidx in ./gradlew :app:dependencies

I ended up removing ~/.AndroidStudio3.5/ too (I'm on 3.5.3). This makes the project compile again, and I discovered the dark mode...

The solution for this is that remove this following dependency:

implementation 'com.android.support:design:26.1.0'

put general dependencies as:

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    //noinspection GradleCompatible
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support:support-compat:26.1.0'
    implementation 'com.android.support:multidex:1.0.3'    
    implementation 'com.android.support:support-v4:26.1.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.facebook.android:audience-network-sdk:4.99.1'
}

Your can use DataSourceBuilder for this purpose.

@Primary
@Bean(name = "dataSource")
@ConfigurationProperties(prefix = "spring.datasource")
public DataSource dataSource(Environment env) {
    final String datasourceUsername = env.getRequiredProperty("spring.datasource.username");
    final String datasourcePassword = env.getRequiredProperty("spring.datasource.password");
    final String datasourceUrl = env.getRequiredProperty("spring.datasource.url");
    final String datasourceDriver = env.getRequiredProperty("spring.datasource.driver-class-name");
    return DataSourceBuilder
            .create()
            .username(datasourceUsername)
            .password(datasourcePassword)
            .url(datasourceUrl)
            .driverClassName(datasourceDriver)
            .build();
}

IF you want to derive usg Boolean true False need to add "[]" around value

<form [formGroup]="form">
  <input type="radio" [value]=true formControlName="gender" >Male
  <input type="radio" [value]=false formControlName="gender">Female
</form>

    async handleResponse(){
      const result = await this.axiosTest();
    }

    async axiosTest () {
    return await axios.get(url)
    .then(function (response) {
            console.log(response.data);
            return response.data;})
.catch(function (error) {
    console.log(error);
});
}

You can find check https://flaviocopes.com/axios/#post-requests url and find some relevant information in the GET section of this post.

I got the same message. But it's not making any sense in my case. My issue is I used a "NotMapped" property by mistake. It probably only means an error of Linq syntax or model class in some cases. The error message seems misleading. The original meaning of this message is you can't call async on same dbcontext more than once in the same request.

[NotMapped]
public int PostId { get; set; }
public virtual Post Post { get; set; }

export default is used to create local registration for Vue component.

Here is a great article that explain more about components https://frontendsociety.com/why-you-shouldnt-use-vue-component-ff019fbcac2e

Use:

df['name'].mode()

or

df['name'].value_counts().idxmax()

Forget about the react first:
This is not related to react and let us understand the basic concepts of Java Script. For Example you have written following function in java script (name is A).

function a() {

};

Q.1) How to call the function that we have defined?
Ans: a();

Q.2) How to pass reference of function so that we can call it latter?
Ans: let fun = a;

Now coming to your question, you have used paranthesis with function name, mean that function will be called when following statement will be render.

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

Then How to correct it?
Simple!! Just remove parenthesis. By this way you have given the reference of that function to onClick event. It will call back your function only when your component is clicked.

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

One suggestion releated to react:
Avoid using inline function as suggested by someone in answers, it may cause performance issue. Avoid following code, It will create instance of same function again and again whenever function will be called (lamda statement creates new instance every time).
Note: and no need to pass event (e) explicitly to the function. you can access it with in the function without passing it.

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

Old one but I would add my answer as per my findings:

var ancestralState = context.findAncestorStateOfType<ParentState>();
      ancestralState.setState(() {
        // here you can access public vars and update state.
        ...
      });

It could be done in Bootstrap 4 using the responsive grid columns. One column for the sidebar and one for the main content.

Bootstrap 4 Sidebar switch to Top Navbar on mobile

<div class="container-fluid h-100">
    <div class="row h-100">
        <aside class="col-12 col-md-2 p-0 bg-dark">
            <nav class="navbar navbar-expand navbar-dark bg-dark flex-md-column flex-row align-items-start">
                <div class="collapse navbar-collapse">
                    <ul class="flex-md-column flex-row navbar-nav w-100 justify-content-between">
                        <li class="nav-item">
                            <a class="nav-link pl-0" href="#">Link</a>
                        </li>
                        ..
                    </ul>
                </div>
            </nav>
        </aside>
        <main class="col">
            ..
        </main>
    </div>
</div>

Alternate sidebar to top
Fixed sidebar to top

For the reverse (Top Navbar that becomes a Sidebar), can be done like this example

When using the 'mat-form-field' MatInputModule needs to be imported also

import { 
    MatToolbarModule, 
    MatButtonModule,
    MatSidenavModule,
    MatIconModule,
    MatListModule ,
    MatStepperModule,
    MatInputModule
} from '@angular/material';

For verbose > 0, fit method logs:

• loss: value of loss function for your training data
• acc: accuracy value for your training data.

Note: If regularization mechanisms are used, they are turned on to avoid overfitting.

if validation_data or validation_split arguments are not empty, fit method logs:

• val_loss: value of loss function for your validation data
• val_acc: accuracy value for your validation data

Note: Regularization mechanisms are turned off at testing time because we are using all the capabilities of the network.

For example, using verbose while training the model helps to detect overfitting which occurs if your acc keeps improving while your val_acc gets worse.

I did a little experimenting to see if I could keep the database name as part of the url. I prefer the promise syntax but it should still work for the callback syntax. Notice below that client.db() is called without passing any parameters.

MongoClient.connect(
    'mongodb://localhost:27017/mytestingdb', 
    { useNewUrlParser: true}
)
.then(client => {

    // The database name is part of the url.  client.db() seems 
    // to know that and works even without a parameter that 
    // relays the db name.
    let db = client.db(); 

    console.log('the current database is: ' + db.s.databaseName);
    // client.close() if you want to

})
.catch(err => console.log(err));

My package.json lists monbodb ^3.2.5.

The 'useNewUrlParser' option is not required if you're willing to deal with a deprecation warning. But it is wise to use at this point until version 4 comes out where presumably the new driver will be the default and you won't need the option anymore.

The OS is not recognizing 'python' command. So try 'py'

Use 'py -m pip'

In my case I had to add the boundary to the header like the following:

const form = new FormData();
form.append(item.name, fs.createReadStream(pathToFile));

const response = await axios({
    method: 'post',
    url: 'http://www.yourserver.com/upload',
    data: form,
    headers: {
        'Content-Type': `multipart/form-data; boundary=${form._boundary}`,
    },
});

This solution is also useful if you're working with React Native.

Be aware to use constant HTTPS or HTTP for all requests. I had the same error msg: "No 'Access-Control-Allow-Origin' header is present on the requested resource."

you have defined the public dir in app root/public

app.use(express.static(__dirname + '/public')); 

so you have to use:

./css/main.css

1. Create .env.development, .env.production files if not exists and add there your API endpoint, for example: VUE_APP_API_ENDPOINT ='http://localtest.me:8000'
2. In main.js file, add this line after imports: axios.defaults.baseURL = process.env.VUE_APP_API_ENDPOINT

And that's it. Axios default base Url is replaced with build mode specific API endpoint. If you need specific baseURL for specific request, do it like this:

this.$axios({ url: 'items', baseURL: 'http://new-url.com' })

Bootstrap 3 - Just adding the "btn" Class worked for me.

Without pointer cursor:

<span class="label label-success">text</span>

With pointer cursor:

<span class="label label-success btn">text</span>

This is my code .This works for me

componentDidMount(){
        axios.get('http://localhost:5000/supplier').then(
            response => {
                console.log(response)
                this.setState({suppliers:response.data.data})
            }
        )
        .catch(error => {
            console.log(error)
        })
        
    }

componentDidUpdate(){
        this.componentDidMount();
}

window.location.reload(); I think this thing is not good for react js

If you are using flutter, Run this command flutter doctor --android-licenses

You could use pandas plot as @Bharath suggest:

import seaborn as sns
sns.set()
df.set_index('App').T.plot(kind='bar', stacked=True)

Output:

Updated:

from matplotlib.colors import ListedColormap df.set_index('App')\ .reindex_axis(df.set_index('App').sum().sort_values().index, axis=1)\ .T.plot(kind='bar', stacked=True, colormap=ListedColormap(sns.color_palette("GnBu", 10)), figsize=(12,6))

Updated Pandas 0.21.0+ reindex_axis is deprecated, use reindex

from matplotlib.colors import ListedColormap

df.set_index('App')\
  .reindex(df.set_index('App').sum().sort_values().index, axis=1)\
  .T.plot(kind='bar', stacked=True,
          colormap=ListedColormap(sns.color_palette("GnBu", 10)), 
          figsize=(12,6))

Output:

You have 2 options here to do that either to discard all your outgoing commits OR to undo specific commit ..

1- Discard all your outgoing commits:

To discard all your outgoing commits For example if you have local branch named master from remote branch, You can:

1- Rename your local branch from master to anything so you can remove it. 2- Remove the renamed branch. 3- create new branch from the master

So now you have a new branch without your commits ..

2- Undo specific commit: To undo specific commit you have to revert the unneeded by:

1- Double click on the unneeded commit. Double click on the unneeded commit 2- Click on revert Click on revert

But FYI the reverted commit will appear in the history of your commits with the revert commit ..

I suggest to use this plugin flutter_easyloading

flutter_easyloading is clean and lightweight Loading widget for Flutter App, easy to use without context, support iOS and Android

Add this to your package's pubspec.yaml file:

dependencies:
  flutter_easyloading: ^2.0.0

Now in your Dart code, you can use:

import 'package:flutter_easyloading/flutter_easyloading.dart';

To use First, initialize FlutterEasyLoading in MaterialApp/CupertinoApp

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter EasyLoading',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'Flutter EasyLoading'),
      builder: EasyLoading.init(),
    );
  }
}

EasyLoading is a singleton, so you can custom loading style any where like this:

import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter_easyloading/flutter_easyloading.dart';
import './custom_animation.dart';

void main() {
  runApp(MyApp());
  configLoading();
}

void configLoading() {
  EasyLoading.instance
    ..displayDuration = const Duration(milliseconds: 2000)
    ..indicatorType = EasyLoadingIndicatorType.fadingCircle
    ..loadingStyle = EasyLoadingStyle.dark
    ..indicatorSize = 45.0
    ..radius = 10.0
    ..progressColor = Colors.yellow
    ..backgroundColor = Colors.green
    ..indicatorColor = Colors.yellow
    ..textColor = Colors.yellow
    ..maskColor = Colors.blue.withOpacity(0.5)
    ..userInteractions = true
    ..customAnimation = CustomAnimation();
}

Then, use per your requirement

import 'package:flutter/material.dart';
import 'package:flutter_easyloading/flutter_easyloading.dart';
import 'package:dio/dio.dart';

class TestPage extends StatefulWidget {
  @override
  _TestPageState createState() => _TestPageState();
}

class _TestPageState extends State<TestPage> {
  @override
  void initState() {
    super.initState();
    // EasyLoading.show();
  }

  @override
  void deactivate() {
    EasyLoading.dismiss();
    super.deactivate();
  }

  void loadData() async {
    try {
      EasyLoading.show();
      Response response = await Dio().get('https://github.com');
      print(response);
      EasyLoading.dismiss();
    } catch (e) {
      EasyLoading.showError(e.toString());
      print(e);
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter EasyLoading'),
      ),
      body: Center(
        child: FlatButton(
          textColor: Colors.blue,
          child: Text('loadData'),
          onPressed: () {
            loadData();
            // await Future.delayed(Duration(seconds: 2));
            // EasyLoading.show(status: 'loading...');
            // await Future.delayed(Duration(seconds: 5));
            // EasyLoading.dismiss();
          },
        ),
      ),
    );
  }
}

Use sudo npm install -g appium.

Working solution is by using in-build: panelClass attribute and set styles in global style.css (with !important):

https://material.angular.io/components/select/api

/* style.css */
.matRole .mat-option-text {
  height: 4em !important;
}

<mat-select panelClass="matRole">...

Two issues jump out:

1. Your getData never returns anything, so its promise (async functions always return a promise) will resolve with undefined when it resolves

2. The error message clearly shows you're trying to directly render the promise getData returns, rather than waiting for it to resolve and then rendering the resolution

Addressing #1: getData should return the result of calling json:

async getData(){
   const res = await axios('/data');
   return await res.json();
}

Addressig #2: We'd have to see more of your code, but fundamentally, you can't do

<SomeElement>{getData()}</SomeElement>

...because that doesn't wait for the resolution. You'd need instead to use getData to set state:

this.getData().then(data => this.setState({data}))
              .catch(err => { /*...handle the error...*/});

...and use that state when rendering:

<SomeElement>{this.state.data}</SomeElement>

Update: Now that you've shown us your code, you'd need to do something like this:

class App extends React.Component{
    async getData() {
        const res = await axios('/data');
        return await res.json(); // (Or whatever)
    }
    constructor(...args) {
        super(...args);
        this.state = {data: null};
    }
    componentDidMount() {
        if (!this.state.data) {
            this.getData().then(data => this.setState({data}))
                          .catch(err => { /*...handle the error...*/});
        }
    }
    render() {
        return (
            <div>
                {this.state.data ? <em>Loading...</em> : this.state.data}
            </div>
        );
    }
}

Futher update: You've indicated a preference for using await in componentDidMount rather than then and catch. You'd do that by nesting an async IIFE function within it and ensuring that function can't throw. (componentDidMount itself can't be async, nothing will consume that promise.) E.g.:

class App extends React.Component{
    async getData() {
        const res = await axios('/data');
        return await res.json(); // (Or whatever)
    }
    constructor(...args) {
        super(...args);
        this.state = {data: null};
    }
    componentDidMount() {
        if (!this.state.data) {
            (async () => {
                try {
                    this.setState({data: await this.getData()});
                } catch (e) {
                    //...handle the error...
                }
            })();
        }
    }
    render() {
        return (
            <div>
                {this.state.data ? <em>Loading...</em> : this.state.data}
            </div>
        );
    }
}

you can use skimage.img_as_ubyte(yourdata) it will make you numpy array ranges from 0->255

from skimage import img_as_ubyte

img = img_as_ubyte(data)
cv2.imshow("Window", img)

localStorage.clear()

That'll clear the stored data. Then refresh and things should start to work.

You have a typo in the import in your LoginComponent's file

import { Component } from '@angular/Core';

It's lowercase c, not uppercase

import { Component } from '@angular/core';

You don't have any data that you're submitting! Try adding this line to your ajax:

data: $('form').serialize(),

Make sure you change the name to match!

Also your data should be submitted inside of a form submit function.

Your code should look something like this:

<script>_x000D_
 $(function () {_x000D_
  $('form').on('submit', function (e) {_x000D_
   e.preventDefault();_x000D_
   $.ajax({_x000D_
    type: 'post',_x000D_
    url: 'company.php',_x000D_
    data: $('form').serialize(),_x000D_
    success: function () {_x000D_
     alert('form was submitted');_x000D_
    }_x000D_
   });_x000D_
  });_x000D_
 });_x000D_
</script>

just serialize the form data and get your problem solved.

data: $('#form_id').serialize(),

To solve this error, you can downgrade your Java version.

Or exports the following option on your terminal:

Linux/MAC:

export JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

Windows:

set JAVA_OPTS=-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee

If this does not work try to exports the java.xml.bind instead.

Linux:

export JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.xml.bind'

Windows:

set JAVA_OPTS=-XX:+IgnoreUnrecognizedVMOptions --add-modules java.xml.bind'

And to save it permanently you can exports the JAVA_OPTS in your profile file on Linux (.zshrc, .bashrc and etc.) or add it as an environment variable permanently on Windows.

ps. This doesn't work for Java 11/11+, which doesn't have Java EE modules. For this option is a good idea, downgrade your Java version or wait for a Flutter update.

Ref: JDK 11: End of the road for Java EE modules

I deal with this issue for some hours. Let's consider the request is Reactjs (javascript) and backend (API) is Asp .Net Core.

in the request, you must set in header Content-Type:

Axios({
            method: 'post',
            headers: { 'Content-Type': 'application/json'},
            url: 'https://localhost:44346/Order/Order/GiveOrder',
            data: order,
          }).then(function (response) {
            console.log(response);
          });

and in backend (Asp .net core API) u must have some setting:

1. in Startup --> ConfigureServices:

#region Allow-Orgin
            services.AddCors(c =>
            {
                c.AddPolicy("AllowOrigin", options => options.AllowAnyOrigin());
            });
            #endregion

2. in Startup --> Configure before app.UseMvc() :

app.UseCors(builder => builder
                .AllowAnyOrigin()
                .AllowAnyMethod()
                .AllowAnyHeader()
                .AllowCredentials());

3. in controller before action:

[EnableCors("AllowOrigin")]

Pim's answer is very helpful. In my case, I have to use

Expires / Max-Age: "Session"

If it is a dateTime, even it is not expired, it still won't send the cookie to the backend:

Expires / Max-Age: "Thu, 21 May 2020 09:00:34 GMT"

Hope it is helpful for future people who may meet same issue.

When you

import App from './App.jsx';

That means it will import whatever you export default. You can rename App class inside App.jsx to whatever you want as long as you export default it will work but you can only have one export default.

So you only need to export default App and you don't need to export the rest.

If you still want to export the rest of the components, you will need named export.

If you have newly upgraded your php version you might be forget to restart your webserver service.

$ npm install cors

After installing cors from npm add the code below to your node app file. It solved my problem.

var express = require('express')
var cors = require('cors')
var app = express()

app.use(cors())

As it turns out, one should not forget to include jacson dependency into the pom file. This solved the issue for me:

<dependency>
    <groupId>com.fasterxml.jackson.module</groupId>
    <artifactId>jackson-module-parameter-names</artifactId>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jdk8</artifactId>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
</dependency>

You may try esm.

Here is some introduction: esm

In my case the reason was since the remote repo artifact (non-central) had dependencies from the Maven Central in the .pom file, and the older version of mvn (older than 3.6.0) was used. So, it tried to check the Maven Central artifacts mentioned in the remote repo's .pom for the specific artifact I've added to my dependencies and faced the Maven Central http access issue behind the scenes (I believe the same as described there: Maven dependencies are failing with a 501 error - that is about using https access to Maven Central by default and prohibiting the http access).

Using more recent Maven (from 3.1 to 3.6.0) made it use https to check Maven Central repo dependencies mentioned in the .pom files of the remote repositories and I no longer face the issue.

Fix urlpatterns in urls.py file

For example, my app name is "simulator",

My URL pattern for login and logout looks like

urlpatterns = [
    ...
    ...
    url(r'^login/$', simulator.views.login_view, name="login"),
    url(r'^logout/$', simulator.views.logout_view, name="logout"),
    ...
    ...

]

Here's a fairly simple way to achieve it by enclosing both the magnifying glass icon and the input field inside a div with relative positioning.

Absolute positioning is applied to the icon, which takes it out of the normal document layout flow. The icon is then positioned inside the input. Left padding is applied to the input so that the user's input appears to the right of the icon.

Note that this example places the magnifying glass icon on the left instead of the right. This is recommended when using <input type="search"> as Chrome adds an X button in the right side of the searchbox. If we placed the icon there it would overlay the X button and look fugly.

Here is the needed Bootstrap markup.

<div class="position-relative">
    <i class="fa fa-search position-absolute"></i>
    <input class="form-control" type="search">
</div>

...and a couple CSS classes for the things which I couldn't do with Bootstrap classes:

i {
    font-size: 1rem;
    color: #333;
    top: .75rem;
    left: .75rem
}

input {
    padding-left: 2.5rem;
}

You may have to fiddle with the values for top, left, and padding-left.

Expanded Widget increases it’s size as much as it can with the space available Since ListView essentially has an infinite height it will cause an error.

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

Here we should use Flexible widget as it will only take the space it required as Expanded take full screen even if there are not enough widgets to render on full screen.

add popper**.js** as dependency instead of popper (only): see the difference in bold.

yarn add popper.js , instead of yarn add popper

it makes the difference.

and include the script according your needs:

as html or the library access as a dependency in SPA applications like react or angular

This is a simple example of a configuration with headers and responseType:

var config = {
  headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
  responseType: 'blob'
};

axios.post('http://YOUR_URL', this.data, config)
  .then((response) => {
  console.log(response.data);
});

Content-Type can be 'application/x-www-form-urlencoded' or 'application/json' and it may work also 'application/json;charset=utf-8'

responseType can be 'arraybuffer', 'blob', 'document', 'json', 'text', 'stream'

In this example, this.data is the data you want to send. It can be a value or an Array. (If you want to send an object you'll probably have to serialize it)

There is no need to use angular http, you can get with js native functions

// you will ned this function to fetch the image blob._x000D_
async function getImage(url, fileName) {_x000D_
     // on the first then you will return blob from response_x000D_
    return await fetch(url).then(r => r.blob())_x000D_
    .then((blob) => { // on the second, you just create a file from that blob, getting the type and name that intend to inform_x000D_
         _x000D_
        return new File([blob], fileName+'.'+   blob.type.split('/')[1]) ;_x000D_
    });_x000D_
}_x000D_
_x000D_
// example url_x000D_
var url = 'https://img.freepik.com/vetores-gratis/icone-realista-quebrado-vidro-fosco_1284-12125.jpg';_x000D_
_x000D_
// calling the function_x000D_
getImage(url, 'your-name-image').then(function(file) {_x000D_
_x000D_
    // with file reader you will transform the file in a data url file;_x000D_
    var reader = new FileReader();_x000D_
    reader.readAsDataURL(file);_x000D_
    reader.onloadend = () => {_x000D_
    _x000D_
    // just putting the data url to img element_x000D_
        document.querySelector('#image').src = reader.result ;_x000D_
    }_x000D_
})

<img src="" id="image"/>

Most simple approach in Template driven forms for min/max validation with out using reactive forms and building any directive, would be to use pattern attribute of html. This has already been explained and answered here please look https://stackoverflow.com/a/63312336/14069524

This question has been asked before. Please see this question.

Using the accepted answer and adapting it to your problem you get:

SELECT tt.*
FROM myTable tt
INNER JOIN
    (SELECT ID, MAX(Date) AS MaxDateTime
    FROM myTable
    GROUP BY ID) groupedtt 
ON tt.ID = groupedtt.ID 
AND tt.Date = groupedtt.MaxDateTime

May be i did not fully understand the problem, but, centering all view inside a ConstraintLayout seems very simple. This is what I used:

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center">

Last two lines did the trick!

Turn the axes off with:

plt.axis('off')

And gridlines with:

plt.grid(b=None)

Just add objects = None in your Questions table. That solved the error for me.

Abstract your initialization into a method, and call the method from mounted and wherever else you want.

new Vue({
  methods:{
    init(){
      //call API
      //Setup game
    }
  },
  mounted(){
    this.init()
  }
})

Then possibly have a button in your template to start over.

<button v-if="playerWon" @click="init">Play Again</button>

In this button, playerWon represents a boolean value in your data that you would set when the player wins the game so the button appears. You would set it back to false in init.

Without using any other libraries:

import * as axios from "axios";

// Mock out all top level functions, such as get, put, delete and post:
jest.mock("axios");

// ...

test("good response", () => {
  axios.get.mockImplementation(() => Promise.resolve({ data: {...} }));
  // ...
});

test("bad response", () => {
  axios.get.mockImplementation(() => Promise.reject({ ... }));
  // ...
});

It is possible to specify the response code:

axios.get.mockImplementation(() => Promise.resolve({ status: 200, data: {...} }));

It is possible to change the mock based on the parameters:

axios.get.mockImplementation((url) => {
    if (url === 'www.example.com') {
        return Promise.resolve({ data: {...} });
    } else {
        //...
    }
});

Jest v23 introduced some syntactic sugar for mocking Promises:

axios.get.mockImplementation(() => Promise.resolve({ data: {...} }));

It can be simplified to

axios.get.mockResolvedValue({ data: {...} });

There is also an equivalent for rejected promises: mockRejectedValue.

Further Reading:

• Jest mocking documentation
• A GitHub discussion that explains about the scope of the jest.mock("axios") line.
• Another answer of mine which addresses applying the techniques above to Axios request interceptors.

instead of using this

Vue.component('tabs', {
    template: `
        <div class="tabs">

The scaling on your example figure is a bit strange but you can force it by plotting the index of each x-value and then setting the ticks to the data points:

import matplotlib.pyplot as plt
x = [0.00001,0.001,0.01,0.1,0.5,1,5]
# create an index for each tick position
xi = list(range(len(x)))
y = [0.945,0.885,0.893,0.9,0.996,1.25,1.19]
plt.ylim(0.8,1.4)
# plot the index for the x-values
plt.plot(xi, y, marker='o', linestyle='--', color='r', label='Square') 
plt.xlabel('x')
plt.ylabel('y') 
plt.xticks(xi, x)
plt.title('compare')
plt.legend() 
plt.show()

I'm surprised no one mentioned the HTML entities   and   which produce horizontal white space equivalent to the characters n and m, respectively. If you want to accumulate horizontal white space quickly, those are more efficient than  .

1. no space
2.   
3.

Along with <space> and  , these are the five entities HTML provides for horizontal white space.

Note that except for  , all entities allow breaking. Whatever text surrounds them will wrap to a new line if it would otherwise extend beyond the container boundary. With   it would wrap to a new line as a block even if the text before   could fit on the previous line.

Depending on your use case, that may be desired or undesired. For me, unless I'm dealing with things like names (John Doe), addresses or references (see eq. 5), breaking as a block is usually undesired.

The variable name you're looking for is ansible_ssh_private_key_file.

You should set it at 'vars' level:

• in the inventory file:

  myHost ansible_ssh_private_key_file=~/.ssh/mykey1.pem
  myOtherHost ansible_ssh_private_key_file=~/.ssh/mykey2.pem
  

• in the host_vars:

  # hosts_vars/myHost.yml
  ansible_ssh_private_key_file: ~/.ssh/mykey1.pem
  
  # hosts_vars/myOtherHost.yml
  ansible_ssh_private_key_file: ~/.ssh/mykey2.pem
  

• in a group_vars file if you use the same key for a group of hosts

• in the vars section of your play:

  - hosts: myHost
    remote_user: ubuntu
    vars_files:
      - vars.yml
    vars:
      ansible_ssh_private_key_file: "{{ key1 }}"
    tasks:
      - name: Echo a hello message
        command: echo hello

I guess the answer you need is referenced here Python sets are not json serializable

Not all datatypes can be json serialized . I guess pickle module will serve your purpose.

updated() should be what you're looking for:

Called after a data change causes the virtual DOM to be re-rendered and patched.

The component’s DOM will have been updated when this hook is called, so you can perform DOM-dependent operations here.

You can also use interceptors to pass the headers

It can save you a lot of code

axios.interceptors.request.use(config => {
  if (config.method === 'POST' || config.method === 'PATCH' || config.method === 'PUT')
    config.headers['Content-Type'] = 'application/json;charset=utf-8';

  const accessToken = AuthService.getAccessToken();
  if (accessToken) config.headers.Authorization = 'Bearer ' + accessToken;

  return config;
});

If you simply place text as a child(ren) of a column, this is the easiest way to have text automatically wrap. Assuming you don't have anything more complicated going on. In those cases, I would think you would create your container sized as you see fit and put another column inside and then your text. This seems to work nicely. Containers want to shrink to the size of its contents, and this seems to naturally conflict with wrapping, which requires more effort.

Column(
  mainAxisSize: MainAxisSize.min,
  children: <Widget>[
    Text('This long text will wrap very nicely if there isn't room beyond the column\'s total width and if you have enough vertical space available to wrap into.',
      style: TextStyle(fontSize: 16, color: primaryColor),
      textAlign: TextAlign.center,),
  ],
),

Seems like you use Angular 4.3 version, I also faced with same problem. Use Angular 4.0.1 and post with code by @trichetricheand and it will work. I am also not sure how to solve it on Angular 4.3 :S

You can use react-pure-lifecycle to add lifecycle functions to functional components.

Example:

import React, { Component } from 'react';
import lifecycle from 'react-pure-lifecycle';

const methods = {
  componentDidMount(props) {
    console.log('I mounted! Here are my props: ', props);
  }
};

const Channels = props => (
<h1>Hello</h1>
)

export default lifecycle(methods)(Channels);

Using official HTML without adding extra CSS styles and classes, it's like native support.

Just add the following code:

$.fn.dropdown = (function() {
    var $bsDropdown = $.fn.dropdown;
    return function(config) {
        if (typeof config === 'string' && config === 'toggle') { // dropdown toggle trigged
            $('.has-child-dropdown-show').removeClass('has-child-dropdown-show');
            $(this).closest('.dropdown').parents('.dropdown').addClass('has-child-dropdown-show');
        }
        var ret = $bsDropdown.call($(this), config);
        $(this).off('click.bs.dropdown'); // Turn off dropdown.js click event, it will call 'this.toggle()' internal
        return ret;
    }
})();

$(function() {
    $('.dropdown [data-toggle="dropdown"]').on('click', function(e) {
        $(this).dropdown('toggle');
        e.stopPropagation();
    });
    $('.dropdown').on('hide.bs.dropdown', function(e) {
        if ($(this).is('.has-child-dropdown-show')) {
            $(this).removeClass('has-child-dropdown-show');
            e.preventDefault();
        }
        e.stopPropagation();
    });
});

Dropdown of bootstrap can be easily changed to infinite level. It's a pity that they didn't do it.

BTW, a hover version: https://github.com/dallaslu/bootstrap-4-multi-level-dropdown

Here is a perfect demo: https://jsfiddle.net/dallaslu/adky6jvs/ (works well with Bootstrap v4.4.1)

According to the matplotlib legend documentation:

The location can also be a 2-tuple giving the coordinates of the lower-left corner of the legend in axes coordinates (in which case bbox_to_anchor will be ignored).

Thus, one could use:

plt.legend(loc=(x, y))

to set the legend's lower left corner to the specified (x, y) position.

For me the solution was to correct the order:

app.UseCors();
app.UseAuthentication();
app.UseAuthorization();

As others have said, the style you're after is actually just the Mac OS checkbox style, so it will look radically different on other devices.

In fact both screenshots you linked show what checkboxes look like on Mac OS in Chrome, the grey one is shown at non-100% zoom levels.

You can try this.

axios.get(
    url,
    {headers: {
            "Access-Control-Allow-Origin" : "*",
            "Content-type": "Application/json",
            "Authorization": `Bearer ${your-token}`
            }   
        }
  )
  .then((response) => {
      var response = response.data;
    },
    (error) => {
      var status = error.response.status
    }
  );

val property is similar to final property in Java. You are allowed to assign it a value only for one time. When you try to reassign it with a value for second time you will get a compilation error. Whereas var property is mutable which you are free to reassign it when you wish and for any times you want.

I'm not sure I understand your question, but if you want the image to fill the entire screen you can use a DecorationImage with a fit of BoxFit.cover.

class BaseLayout extends StatelessWidget{
  @override
  Widget build(BuildContext context){
    return Scaffold(
      body: Container(
        decoration: BoxDecoration(
          image: DecorationImage(
            image: AssetImage("assets/images/bulb.jpg"),
            fit: BoxFit.cover,
          ),
        ),
        child: null /* add child content here */,
      ),
    );
  }
}

For your second question, here is a link to the documentation on how to embed resolution-dependent asset images into your app.

  <TextView
        android:id="@+id/usage"
        android:layout_marginTop="220dip"
        android:layout_marginLeft="45dip"
        android:layout_marginRight="15dip"
        android:typeface="serif"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Google "
        android:textColor="#030900"/>


usage.text="hello world"

If you are trying to do basic auth, you can try this:

const username = ''
const password = ''

const token = Buffer.from(`${username}:${password}`, 'utf8').toString('base64')

const url = 'https://...'
const data = {
...
}

axios.post(url, data, {
  headers: {
 'Authorization': `Basic ${token}`
},
})

This worked for me. Hope that helps

Post Django version 1.9, on_delete became a required argument, i.e. from Django 2.0.

In older versions, it defaults to CASCADE.

So, if you want to replicate the functionality that you used in earlier versions. Use the following argument.

categorie = models.ForeignKey('Categorie', on_delete = models.CASCADE)

This will have the same effect as that was in earlier versions, without specifying it explicitly.

Official Documentation on other arguments that go with on_delete

If your dump file doesn't have DEFINER, make sure these lines below are also removed if they're there, or commented-out with --:

At the start:

-- SET @@SESSION.SQL_LOG_BIN= 0;
-- SET @@GLOBAL.GTID_PURGED=/*!80000 '+'*/ '';

At the end:

-- SET @@SESSION.SQL_LOG_BIN = @MYSQLDUMP_TEMP_LOG_BIN;

As Far my experience in pandas I would like to answer.

The 'inplace=True' argument stands for the data frame has to make changes permanent eg.

    df.dropna(axis='index', how='all', inplace=True)

changes the same dataframe (as this pandas find NaN entries in index and drops them). If we try

    df.dropna(axis='index', how='all')

pandas shows the dataframe with changes we make but will not modify the original dataframe 'df'.

I Had the same issue and finally discovered the reason. In my case it was a badly written Java method:

@FormUrlEncoded
@POST("register-user/")
Call<RegisterUserApiResponse> registerUser(
        @Field("email") String email,
        @Field("password") String password,            
        @Field("date") String birthDate,
);

Note the illegal comma after the "date" field. For some reason the compiler could not reveal this exact error, and came with the ':app:compileDebugKotlin'. > Compilation error thing.

The simplest answer is to set the selected option to true or false.

<option :selected="selectedDay === 1" value="1">1</option>

Where the data object is:

data() {
    return {
        selectedDay: '1',
        // [1, 2, 3, ..., 31]
        days: Array.from({ length: 31 }, (v, i) => i).slice(1)
    }
}

This is an example to set the selected month day:

<select v-model="selectedDay" style="width:10%;">
    <option v-for="day in days" :selected="selectedDay === day">{{ day }}</option>
</select>

On your data set:

{
    data() {
        selectedDay: 1,
        // [1, 2, 3, ..., 31]
        days: Array.from({ length: 31 }, (v, i) => i).slice(1)
    },
    mounted () {
        let selectedDay = new Date();
        this.selectedDay = selectedDay.getDate(); // Sets selectedDay to the today's number of the month
    }
}

Another alternative is to nest conditions

<ng-container *ngIf="foo === 1;else second"></ng-container>
<ng-template #second>
    <ng-container *ngIf="foo === 2;else third"></ng-container>
</ng-template>
<ng-template #third></ng-template>

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")

Try with this:

const { jasper } = this.state; //Gets the object from state
jasper.name = 'A new name'; //do whatever you want with the object
this.setState({jasper}); //Replace the object in state

If we are using TypeScript, we can update the type definition file by running the command npm install @types/node from the terminal or command prompt.

I was trying to organize my vue app code, and came across this question , since I have a lot of logic in my component and can not use other sub-coponents , it makes sense to use many functions in a separate js file and call them in the vue file, so here is my attempt

1)The Component (.vue file)

//MyComponent.vue file
<template>
  <div>
  <div>Hello {{name}}</div>
  <button @click="function_A">Read Name</button>
  <button @click="function_B">Write Name</button>
  <button @click="function_C">Reset</button>
  <div>{{message}}</div>
  </div>
 </template>


<script>
import Mylib from "./Mylib"; // <-- import
export default {
  name: "MyComponent",
  data() {
    return {
      name: "Bob",
      message: "click on the buttons"
    };
  },
  methods: {
    function_A() {
      Mylib.myfuncA(this); // <---read data
    },
    function_B() {
      Mylib.myfuncB(this); // <---write data
    },
    function_C() {
      Mylib.myfuncC(this); // <---write data
    }
  }
};
</script>

2)The External js file

//Mylib.js
let exports = {};

// this (vue instance) is passed as that , so we
// can read and write data from and to it as we please :)
exports.myfuncA = (that) => {
  that.message =
  "you hit ''myfuncA'' function that is located in Mylib.js  and data.name = " +
    that.name;
};

exports.myfuncB = (that) => {
  that.message =
  "you hit ''myfuncB'' function that is located in Mylib.js and now I will change the name to Nassim";
  that.name = "Nassim"; // <-- change name to Nassim
};

exports.myfuncC = (that) => {
  that.message =
  "you hit ''myfuncC'' function that is located in Mylib.js and now I will change the name back to Bob";
  that.name = "Bob"; // <-- change name to Bob
};

export default exports;

3)see it in action : https://codesandbox.io/s/distracted-pare-vuw7i?file=/src/components/MyComponent.vue

edit

after getting more experience with Vue , I found out that you could use mixins too to split your code into different files and make it easier to code and maintain see https://vuejs.org/v2/guide/mixins.html

It requires a bit of rearranging, but when does a good job to replace conditionals above. Here's the example from above written using the declarative syntax. Note that test3 stage is now two different stages. One that runs on the master branch and one that runs on anything else.

stage ('Test 3: Master') {
    when { branch 'master' }
    steps { 
        echo 'I only execute on the master branch.' 
    }
}

stage ('Test 3: Dev') {
    when { not { branch 'master' } }
    steps {
        echo 'I execute on non-master branches.'
    }
}

You need to add JAX-B dependencies when using JDK 9+. For Android Studio user, you'll need to add this to your build.gradle's dependencies {} block:

// Add missing dependencies for JDK 9+
if (JavaVersion.current().ordinal() >= JavaVersion.VERSION_1_9.ordinal()) {
    // If you're using @AutoValue or any libs that requires javax.annotation (like Dagger)
    compileOnly 'com.github.pengrad:jdk9-deps:1.0'
    compileOnly 'javax.annotation:javax.annotation-api:1.3.2'

    // If you're using Kotlin
    kapt "com.sun.xml.bind:jaxb-core:2.3.0.1"
    kapt "javax.xml.bind:jaxb-api:2.3.1"
    kapt "com.sun.xml.bind:jaxb-impl:2.3.2"

    // If you're using Java
    annotationProcessor "com.sun.xml.bind:jaxb-core:2.3.0.1"
    annotationProcessor "javax.xml.bind:jaxb-api:2.3.1"

    testAnnotationProcessor "com.sun.xml.bind:jaxb-core:2.3.0.1"
    testAnnotationProcessor "javax.xml.bind:jaxb-api:2.3.1"
}

This worked for me:

export function modalSave(name,id){
  console.log('modalChanges action ' + name+id);  

  return {
    type: 'EDIT',
    payload: new Promise((resolve, reject) => {
      const value = {
        Name: name,
        ID: id,
      } 

      axios({
        method: 'put',
        url: 'http://localhost:53203/api/values',
        data: value,
        config: { headers: {'Content-Type': 'multipart/form-data' }}
      })
       .then(function (response) {
         if (response.status === 200) {
           console.log("Update Success");
           resolve();
         }
       })
       .catch(function (response) {
         console.log(response);
         resolve();
       });
    })
  };
}

When you are using Vue directives, the expressions are evaluated in the context of Vue, so you don't need to wrap things in {}.

@click is just shorthand for v-on:click directive so the same rules apply.

In your case, simply use @click="addToCount(item.contactID)"

keras predict_classes (docs) outputs A numpy array of class predictions. Which in your model case, the index of neuron of highest activation from your last(softmax) layer. [[0]] means that your model predicted that your test data is class 0. (usually you will be passing multiple image, and the result will look like [[0], [1], [1], [0]] )

You must convert your actual label (e.g. 'cancer', 'not cancer') into binary encoding (0 for 'cancer', 1 for 'not cancer') for binary classification. Then you will interpret your sequence output of [[0]] as having class label 'cancer'

The ideal way would be to add CORS support to your server.

You could also try using a separate jsonp module. As far as I know axios does not support jsonp. So I am not sure if the method you are using would qualify as a valid jsonp request.

There is another hackish work around for the CORS problem. You will have to deploy your code with an nginx server serving as a proxy for both your server and your client. The thing that will do the trick us the proxy_pass directive. Configure your nginx server in such a way that the location block handling your particular request will proxy_pass or redirect your request to your actual server. CORS problems usually occur because of change in the website domain. When you have a singly proxy serving as the face of you client and you server, the browser is fooled into thinking that the server and client reside in the same domain. Ergo no CORS.

Consider this example.

Your server is my-server.com and your client is my-client.com Configure nginx as follows:

// nginx.conf

upstream server {
    server my-server.com;
}

upstream client {
    server my-client.com;
}

server {
    listen 80;

    server_name my-website.com;
    access_log /path/to/access/log/access.log;
    error_log /path/to/error/log/error.log;

    location / {
        proxy_pass http://client;
    }

    location ~ /server/(?<section>.*) {
        rewrite ^/server/(.*)$ /$1 break;
        proxy_pass http://server;
    }
}

Here my-website.com will be the resultant name of the website where the code will be accessible (name of the proxy website). Once nginx is configured this way. You will need to modify the requests such that:

• All API calls change from my-server.com/<API-path> to my-website.com/server/<API-path>

In case you are not familiar with nginx I would advise you to go through the documentation.

To explain what is happening in the configuration above in brief:

• The upstreams define the actual servers to whom the requests will be redirected
• The server block is used to define the actual behaviour of the nginx server.
• In case there are multiple server blocks the server_name is used to identify the block which will be used to handle the current request.
• The error_log and access_log directives are used to define the locations of the log files (used for debugging)
• The location blocks define the handling of different types of requests:
  1. The first location block handles all requests starting with / all these requests are redirected to the client
  2. The second location block handles all requests starting with /server/<API-path>. We will be redirecting all such requests to the server.

Note: /server here is being used to distinguish the client side requests from the server side requests. Since the domain is the same there is no other way of distinguishing requests. Keep in mind there is no such convention that compels you to add /server in all such use cases. It can be changed to any other string eg. /my-server/<API-path>, /abc/<API-path>, etc.

Even though this technique should do the trick, I would highly advise you to add CORS support to the server as this is the ideal way situations like these should be handled.

If you wish to avoid doing all this while developing you could for this chrome extension. It should allow you to perform cross domain requests during development.

mode: 'no-cors' won’t magically make things work. In fact it makes things worse, because one effect it has is to tell browsers, “Block my frontend JavaScript code from looking at contents of the response body and headers under all circumstances.” Of course you almost never want that.

What happens with cross-origin requests from frontend JavaScript is that browsers by default block frontend code from accessing resources cross-origin. If Access-Control-Allow-Origin is in a response, then browsers will relax that blocking and allow your code to access the response.

But if a site sends no Access-Control-Allow-Origin in its responses, your frontend code can’t directly access responses from that site. In particular, you can’t fix it by specifying mode: 'no-cors' (in fact that’ll ensure your frontend code can’t access the response contents).

However, one thing that will work: if you send your request through a CORS proxy.

You can also easily deploy your own proxy to Heroku in literally just 2-3 minutes, with 5 commands:

git clone https://github.com/Rob--W/cors-anywhere.git
cd cors-anywhere/
npm install

After running those commands, you’ll end up with your own CORS Anywhere server running at, for example, https://cryptic-headland-94862.herokuapp.com/.

Prefix your request URL with your proxy URL; for example:

https://cryptic-headland-94862.herokuapp.com/https://example.com

Adding the proxy URL as a prefix causes the request to get made through your proxy, which then:

1. Forwards the request to https://example.com.
2. Receives the response from https://example.com.
3. Adds the Access-Control-Allow-Origin header to the response.
4. Passes that response, with that added header, back to the requesting frontend code.

The browser then allows the frontend code to access the response, because that response with the Access-Control-Allow-Origin response header is what the browser sees.

This works even if the request is one that triggers browsers to do a CORS preflight OPTIONS request, because in that case, the proxy also sends back the Access-Control-Allow-Headers and Access-Control-Allow-Methods headers needed to make the preflight successful.

I can hit this endpoint, http://catfacts-api.appspot.com/api/facts?number=99 via Postman

https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS explains why it is that even though you can access the response with Postman, browsers won’t let you access the response cross-origin from frontend JavaScript code running in a web app unless the response includes an Access-Control-Allow-Origin response header.

http://catfacts-api.appspot.com/api/facts?number=99 has no Access-Control-Allow-Origin response header, so there’s no way your frontend code can access the response cross-origin.

Your browser can get the response fine and you can see it in Postman and even in browser devtools—but that doesn’t mean browsers will expose it to your code. They won’t, because it has no Access-Control-Allow-Origin response header. So you must instead use a proxy to get it.

The proxy makes the request to that site, gets the response, adds the Access-Control-Allow-Origin response header and any other CORS headers needed, then passes that back to your requesting code. And that response with the Access-Control-Allow-Origin header added is what the browser sees, so the browser lets your frontend code actually access the response.

So I am trying to pass in an object, to my Fetch which will disable CORS

You don’t want to do that. To be clear, when you say you want to “disable CORS” it seems you actually mean you want to disable the same-origin policy. CORS itself is actually a way to do that — CORS is a way to loosen the same-origin policy, not a way to restrict it.

But anyway, it’s true you can — in just your local environment — do things like give your browser runtime flags to disable security and run insecurely, or you can install a browser extension locally to get around the same-origin policy, but all that does is change the situation just for you locally.

No matter what you change locally, anybody else trying to use your app is still going to run into the same-origin policy, and there’s no way you can disable that for other users of your app.

You most likely never want to use mode: 'no-cors' in practice except in a few limited cases, and even then only if you know exactly what you’re doing and what the effects are. That’s because what setting mode: 'no-cors' actually says to the browser is, “Block my frontend JavaScript code from looking into the contents of the response body and headers under all circumstances.” In most cases that’s obviously really not what you want.

As far as the cases when you would want to consider using mode: 'no-cors', see the answer at What limitations apply to opaque responses? for the details. The gist of it is that the cases are:

• In the limited case when you’re using JavaScript to put content from another origin into a <script>, <link rel=stylesheet>, <img>, <video>, <audio>, <object>, <embed>, or <iframe> element (which works because embedding of resources cross-origin is allowed for those) — but for some reason you don’t want to or can’t do that just by having the markup of the document use the resource URL as the href or src attribute for the element.

• When the only thing you want to do with a resource is to cache it. As alluded to in the answer What limitations apply to opaque responses?, in practice the scenario that applies to is when you’re using Service Workers, in which case the API that’s relevant is the Cache Storage API.

But even in those limited cases, there are some important gotchas to be aware of; see the answer at What limitations apply to opaque responses? for the details.

I have also tried to pass in the object { mode: 'opaque'}

There is no mode: 'opaque' request mode — opaque is instead just a property of the response, and browsers set that opaque property on responses from requests sent with the no-cors mode.

But incidentally the word opaque is a pretty explicit signal about the nature of the response you end up with: “opaque” means you can’t see it.

"react-router-dom": "^4.2.2"

For navigate to another page (About page in my case), I installed prop-types. Then I import it in the corresponding component.And I used this.context.router.history.push('/about').And it gets navigated.

My code is,

import React, { Component } from 'react';
import '../assets/mystyle.css';
import { Redirect } from 'react-router';
import PropTypes from 'prop-types';

export default class Header extends Component {   
    viewAbout() {
       this.context.router.history.push('/about')
    }
    render() {
        return (
            <header className="App-header">
                <div className="myapp_menu">
                    <input type="button" value="Home" />
                    <input type="button" value="Services" />
                    <input type="button" value="Contact" />
                    <input type="button" value="About" onClick={() => { this.viewAbout() }} />
                </div>
            </header>
        )
    }
}
Header.contextTypes = {
    router: PropTypes.object
  };

Just in case if anyone is interested in labeling horizontal barplot graph, I modified Sharon's answer as below:

def show_values_on_bars(axs, h_v="v", space=0.4):
    def _show_on_single_plot(ax):
        if h_v == "v":
            for p in ax.patches:
                _x = p.get_x() + p.get_width() / 2
                _y = p.get_y() + p.get_height()
                value = int(p.get_height())
                ax.text(_x, _y, value, ha="center") 
        elif h_v == "h":
            for p in ax.patches:
                _x = p.get_x() + p.get_width() + float(space)
                _y = p.get_y() + p.get_height()
                value = int(p.get_width())
                ax.text(_x, _y, value, ha="left")

    if isinstance(axs, np.ndarray):
        for idx, ax in np.ndenumerate(axs):
            _show_on_single_plot(ax)
    else:
        _show_on_single_plot(axs)

Two parameters explained:

h_v - Whether the barplot is horizontal or vertical. "h" represents the horizontal barplot, "v" represents the vertical barplot.

space - The space between value text and the top edge of the bar. Only works for horizontal mode.

Example:

show_values_on_bars(sns_t, "h", 0.3)

for i in range(100):
try:
  #Your code here
  break
except:
  continue

This one worked for me.

I got this same error when i was trying to make a table with name "admin". Then I used @Table annotation and gave table a different name like @Table(name = "admins"). I think some words are reserved (like :- keywords in java) and you can not use them.

@Entity
@Table(name = "admins")
public class Admin extends TrackedEntity {

}

elec_and_weather['DEMAND_t-%i'% k] = np.zeros(len(elec_and_weather['DEMAND']))'

The error comes at the end of the line where you have the (') sign; this error always means that you have a syntax error.

SHOW VARIABLES LIKE 'validate_password%';

mysql> SET GLOBAL validate_password.length = 6;

mysql> SET GLOBAL validate_password.number_count = 0;

mysql> SET GLOBAL validate_password.policy=LOW;

SHOW VARIABLES LIKE 'validate_password%';

Easy. Use .shape.

>>> nparray.shape
(5, 6) #Returns a tuple of array dimensions.

If you want to call other api routes in the future and keep your token in the store then try using redux middleware.

The middleware could listen for the an api action and dispatch api requests through axios accordingly.

Here is a very basic example:

actions/api.js

export const CALL_API = 'CALL_API';

function onSuccess(payload) {
  return {
    type: 'SUCCESS',
    payload
  };
}

function onError(payload) {
  return {
    type: 'ERROR',
    payload,
    error: true
  };
}

export function apiLogin(credentials) {
  return {
    onSuccess,
    onError,
    type: CALL_API,
    params: { ...credentials },
    method: 'post',
    url: 'login'
  };
}

middleware/api.js

import axios from 'axios';
import { CALL_API } from '../actions/api';

export default ({ getState, dispatch }) => next => async action => {
  // Ignore anything that's not calling the api
  if (action.type !== CALL_API) {
    return next(action);
  }

  // Grab the token from state
  const { token } = getState().session;

  // Format the request and attach the token.
  const { method, onSuccess, onError, params, url } = action;

  const defaultOptions = {
    headers: {
      Authorization: token ? `Token ${token}` : '',
    }
  };

  const options = {
    ...defaultOptions,
    ...params
  };

  try {
    const response = await axios[method](url, options);
    dispatch(onSuccess(response.data));
  } catch (error) {
    dispatch(onError(error.data));
  }

  return next(action);
};

How to post file using an object in memory (like a JSON object):

import axios from 'axios';
import * as FormData  from 'form-data'

async function sendData(jsonData){
    // const payload = JSON.stringify({ hello: 'world'});
    const payload = JSON.stringify(jsonData);
    const bufferObject = Buffer.from(payload, 'utf-8');
    const file = new FormData();

    file.append('upload_file', bufferObject, "b.json");

    const response = await axios.post(
        lovelyURL,
        file,
        headers: file.getHeaders()
    ).toPromise();


    console.log(response?.data);
}

You are getting the two thinks mixed.

You have "react-cookie" and "axios"

react-cookie => is for handling the cookie on the client side

axios => is for sending ajax requests to the server

With that info, if you want the cookies from the client side to be communicated in the backend side as well, you will need to connect them together.

Note from "react-cookie" Readme:

Isomorphic cookies!

To be able to access user cookies while doing server-rendering, you can use plugToRequest or setRawCookie.

link to readme

If this is what you need, great.

If not, please comment so I could elaborate more.

The Angular microsyntax lets you configure a directive in a compact, friendly string. The microsyntax parser translates that string into attributes on the <ng-template>. The let keyword declares a template input variable that you reference within the template.

Basic Example

folder = async () => {
    let fold = await getFold();
    //await localStorage.save('folder');
    return fold;
  };

The solution was as simple as adding plt.show() at the end of the code snippet:

import numpy as np
np.random.seed(123)
from keras.models import Sequential
from keras.layers import Dense, Dropout, Activation, Flatten
from keras.layers import Convolution2D, MaxPooling2D
from keras.utils import np_utils
from keras.datasets import mnist
(X_train,y_train),(X_test,y_test) = mnist.load_data()
print X_train.shape
from matplotlib import pyplot as plt
plt.imshow(X_train[0])
plt.show()

One alternative - and more lightweight approach to your problem - might be, just editing the array temporarily and then assigning the whole array back to your variable. Because as Vue does not watch individual items it will watch the whole variable being updated.

So you this should work as well:

var tempArray[];

tempArray = this.items;

tempArray[targetPosition]  = value;

this.items = tempArray;

This then should also update your DOM.

I tried using Adam B's answer, however, it didn't work for me. Instead, I found the following workaround for adding legends to pointplots.

import matplotlib.patches as mpatches
red_patch = mpatches.Patch(color='#bb3f3f', label='Label1')
black_patch = mpatches.Patch(color='#000000', label='Label2')

In the pointplots, the color can be specified as mentioned in previous answers. Once these patches corresponding to the different plots are set up,

plt.legend(handles=[red_patch, black_patch])

And the legend ought to appear in the pointplot.

The model has a save method, which saves all the details necessary to reconstitute the model. An example from the keras documentation:

from keras.models import load_model

model.save('my_model.h5')  # creates a HDF5 file 'my_model.h5'
del model  # deletes the existing model

# returns a compiled model
# identical to the previous one
model = load_model('my_model.h5')

@ImportanceOfBeingErnest 's answer is good if you only want to change the linewidth inside the legend box. But I think it is a bit more complex since you have to copy the handles before changing legend linewidth. Besides, it can not change the legend label fontsize. The following two methods can not only change the linewidth but also the legend label text font size in a more concise way.

Method 1

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the individual lines inside legend and set line width
for line in leg.get_lines():
    line.set_linewidth(4)
# get label texts inside legend and set font size
for text in leg.get_texts():
    text.set_fontsize('x-large')

plt.savefig('leg_example')
plt.show()

Method 2

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the lines and texts inside legend box
leg_lines = leg.get_lines()
leg_texts = leg.get_texts()
# bulk-set the properties of all lines and texts
plt.setp(leg_lines, linewidth=4)
plt.setp(leg_texts, fontsize='x-large')
plt.savefig('leg_example')
plt.show()

The above two methods produce the same output image:

I have a little addition to @Andreys answer to his own question.

It seems that you do not have to call the callback in the cors(req, res, cb) function, so you can just call the cors module at the top of your function, without embedding all your code in the callback. This is much quicker if you want to implement cors afterwards.

exports.exampleFunction = functions.https.onRequest((request, response) => {
    cors(request, response, () => {});
    return response.send("Hello from Firebase!");
});

Do not forget to init cors as mentioned in the opening post:

const cors = require('cors')({origin: true});

Be careful that don't use [email protected] or [email protected] with [email protected]. URL will update after history.push or any other push to history instructions but navigation is not working with react-router. use npm install [email protected] to change the history version. see React router not working after upgrading to v 5.

I think this problem is happening when push to history happened. for example using <NavLink to="/apps"> facing a problem in NavLink.js that consume <RouterContext.Consumer>. context.location is changing to an object with action and location properties when the push to history occurs. So currentLocation.pathname is null to match the path.

I also got this error .I was using Text inside body after changing to XML(text/xml) , got result as expected.

• If your request is XML Request use XML(text/xml).

• If your request is JSON Request use JSON(application/json)

Another way is that you can use bitmask for each optional field. and set those bits if values are set and reset those bits which values are not set

enum bitsV {
    baz_present = 1; // 0x01
    baz1_present = 2; // 0x02

}
message Foo {
    uint32 bitMask;
    required int32 bar = 1;
    optional int32 baz = 2;
    optional int32 baz1 = 3;
}

On parsing check for value of bitMask.

if (bitMask & baz_present)
    baz is present

if (bitMask & baz1_present)
    baz1 is present

The django-admin maybe the wrong file.I met the same problem which I did not found on a different computer the same set-up flow.

After comparing two project, I found several difference at manage.py and settings.py, then I realized I created 2.0 django project but run it with python2.

runwhich django-adminin iterm

/Library/Frameworks/Python.framework/Versions/3.6/bin/django-admin

It looks like I got a django-admin in python3 which I didn't know why.So I tried to get the correct django-amin.

pip show django

then I got

Name: Django
Version: 1.11a1
Summary: A high-level Python Web framework that encourages rapid development and clean, pragmatic design.
Home-page: https://www.djangoproject.com/
Author: Django Software Foundation
Author-email: [email protected]
License: BSD
Location: /Library/Python/2.7/site-packages
Requires: pytz

In/Library/Python/2.7/site-packages, I found the django-admin

/Library/Python/2.7/site-packages/django/bin/django-admin.py

So I created project again by

/Library/Python/2.7/site-packages/django/bin/django-admin.py startproject myproject

then run

cd myproject
python manage.py runserver

succeeded

For initial array, better use object instead of array, as then you won't be worrying about the indexes and it will be much more clear what is what:

const initialArr = [{
    color: "blue",
    text: "text1"
}, {
    color: "red",
    text: "text2"
}];

For actual mapping, use JS Array map instead of for loop - for loop should be used in cases when there's no actual array defined, like displaying something a certain number of times:

onPress = () => {
    ...
};

renderButtons() {
    return initialArr.map((item) => {
        return (
            <Button 
                style={{ borderColor: item.color }}
                onPress={this.onPress}
            >
                {item.text}
            </Button>
        );
    });
}

...

render() {
    return (
        <View style={...}>
            {
                this.renderButtons()
            }
        </View>
    )
}

I moved the mapping to separate function outside of render method for more readable code. There are many other ways to loop through list of elements in react native, and which way you'll use depends on what do you need to do. Most of these ways are covered in this article about React JSX loops, and although it's using React examples, everything from it can be used in React Native. Please check it out if you're interested in this topic!

Also, not on the topic on the looping, but as you're already using the array syntax for defining the onPress function, there's no need to bind it again. This, again, applies only if the function is defined using this syntax within the component, as the arrow syntax auto binds the function.

EDIT:

After your comments this actually makes perfect sense why you don't get a histogram of each different value. There are 1.4 million rows, and ten discrete buckets. So apparently each bucket is exactly 10% (to within what you can see in the plot).

A quick rerun of your data:

In [25]: df.hist(column='Trip_distance')

Prints out absolutely fine.

The df.hist function comes with an optional keyword argument bins=10 which buckets the data into discrete bins. With only 10 discrete bins and a more or less homogeneous distribution of hundreds of thousands of rows, you might not be able to see the difference in the ten different bins in your low resolution plot:

In [34]: df.hist(column='Trip_distance', bins=50)

In order to use torchsummary type:

from torchsummary import summary

Install it first if you don't have it.

pip install torchsummary 

And then you can try it, but note from some reason it is not working unless I set model to cuda alexnet.cuda:

from torchsummary import summary
help(summary)
import torchvision.models as models
alexnet = models.alexnet(pretrained=False)
alexnet.cuda()
summary(alexnet, (3, 224, 224))
print(alexnet)

The summary must take the input size and batch size is set to -1 meaning any batch size we provide.

If we set summary(alexnet, (3, 224, 224), 32) this means use the bs=32.

summary(model, input_size, batch_size=-1, device='cuda')

Out:

Help on function summary in module torchsummary.torchsummary:

summary(model, input_size, batch_size=-1, device='cuda')

What is the meaning of parameter -1?

You can read -1 as dynamic number of parameters or "anything". Because of that there can be only one parameter -1 in view().

If you ask x.view(-1,1) this will output tensor shape [anything, 1] depending on the number of elements in x. For example:

import torch
x = torch.tensor([1, 2, 3, 4])
print(x,x.shape)
print("...")
print(x.view(-1,1), x.view(-1,1).shape)
print(x.view(1,-1), x.view(1,-1).shape)

Will output:

tensor([1, 2, 3, 4]) torch.Size([4])
...
tensor([[1],
        [2],
        [3],
        [4]]) torch.Size([4, 1])
tensor([[1, 2, 3, 4]]) torch.Size([1, 4])

This is not an answer over @T.J. Crowder's one. Just an comment responding to the comment "And actually, if the exception is going to be converted to a rejection, I'm not sure whether I am actually bothered if it's an Error. My reasons for throwing only Error probably don't apply."

if your code is using async/await, then it is still a good practice to reject with an Error instead of 400:

try {
  await foo('a');
}
catch (e) {
  // you would still want `e` to be an `Error` instead of `400`
}

After searching and combining answers, 2018 version of this question and it worked for me:

1) On navigation tab change it to project view

2) Navigate to [YourProjectName]/.idea/libraries/

3) Delete all files starting with Gradle__com_android_support_[libraryName]

E.g: Gradle__com_android_support_animated_vector_drawable_26_0_0.xml

4) In your gradle file define a variable and use it to replace version number like ${variableName}

Def variable:

ext {
    support_library_version = '28.0.0' //use the version of choice
}

Use variable:

implementation "com.android.support:cardview-v7:${support_library_version}"

example gradle:

dependencies {
    ext {
        support_library_version = '28.0.0' //use the version of choice
    }

    implementation fileTree(include: ['*.jar'], dir: 'libs')

    implementation "com.android.support:animated-vector-drawable:${support_library_version}"
    implementation "com.android.support:appcompat-v7:${support_library_version}"
    implementation "com.android.support:customtabs:${support_library_version}"
    implementation "com.android.support:cardview-v7:${support_library_version}"
    implementation "com.android.support:support-compat:${support_library_version}"
    implementation "com.android.support:support-v4:${support_library_version}"
    implementation "com.android.support:support-core-utils:${support_library_version}"
    implementation "com.android.support:support-core-ui:${support_library_version}"
    implementation "com.android.support:support-fragment:${support_library_version}"
    implementation "com.android.support:support-media-compat:${support_library_version}"
    implementation "com.android.support:appcompat-v7:${support_library_version}"
    implementation "com.android.support:recyclerview-v7:${support_library_version}"
    implementation "com.android.support:design:${support_library_version}"

}

The output of ps aux looks like you did not start docker through systemd/systemctl.

It looks like you started it with:

sudo dockerd -H gridsim1103:2376

When you try to stop it with systemctl, nothing should happen as the resulting dockerd process is not controlled by systemd. So the behavior you see is expected.

The correct way to start docker is to use systemd/systemctl:

systemctl enable docker
systemctl start docker

After this, docker should start on system start.

EDIT: As you already have the docker process running, simply kill it by pressing CTRL+C on the terminal you started it. Or send a kill signal to the process.

The Jenkinsfile is written in groovy which uses the Java (and C) form of comments:

/* this
   is a
   multi-line comment */

// this is a single line comment

non-null assertion operator

With the non-null assertion operator we can tell the compiler explicitly that an expression has value other than null or undefined. This is can be useful when the compiler cannot infer the type with certainty but we more information than the compiler.

Example

TS code

function simpleExample(nullableArg: number | undefined | null) {
   const normal: number = nullableArg; 
    //   Compile err: 
    //   Type 'number | null | undefined' is not assignable to type 'number'.
    //   Type 'undefined' is not assignable to type 'number'.(2322)

   const operatorApplied: number = nullableArg!; 
    // compiles fine because we tell compiler that null | undefined are excluded 
}

Compiled JS code

Note that the JS does not know the concept of the Non-null assertion operator since this is a TS feature

"use strict";
function simpleExample(nullableArg) {
    const normal = nullableArg;
    const operatorApplied = nullableArg;
 }

You probably want to assign the lastname you are reading out here

lastname = sheet.cell(row=r, column=3).value

to something; currently the program just forgets it

you could do that two lines after, like so

unpaidMembers[name] = lastname, email

your program will still crash at the same place, because .items() still won't give you 3-tuples but rather something that has this structure: (name, (lastname, email))

good news is, python can handle this

for name, (lastname, email) in unpaidMembers.items():

etc.

you can vertically align your container by making the parent container flex and adding align-items:center:

body {
  display:flex;
  align-items:center;
}

Updated Pen

As already specified we add to the AppServiceProvider.php in App/Providers

use Illuminate\Support\Facades\Schema;  // add this

/**
 * Bootstrap any application services.
 *
 * @return void
 */
public function boot()
{
    Schema::defaultStringLength(191); // also this line
}

you can see more details in the link bellow (search for "Index Lengths & MySQL / MariaDB") https://laravel.com/docs/5.5/migrations

BUT WELL THAT's not what I published all about! the thing is even when doing the above you will likely to get another error (that's when you run php artisan migrate command and because of the problem of the length, the operation will likely stuck in the middle. solution is below, and the user table is likely created without the rest or not totally correctly) we need to roll back. the default roll back will not work. because the operation of migration didn't like finish. you need to delete the new created tables in the database manually.

we can do it using tinker as in below:

L:\todos> php artisan tinker

Psy Shell v0.8.15 (PHP 7.1.10 — cli) by Justin Hileman

>>> Schema::drop('users')

=> null

I myself had a problem with users table.

after that you're good to go

php artisan migrate:rollback

php artisan migrate

I got this on Firefox (FF58). I fixed this with:

1. It is still experimental on Firefox (from v54): You have to set to true the variable dom.moduleScripts.enabled in about:config

Source: Import page on mozilla (See Browser compatibility)

2. Add type="module" to your script tag where you import the js file

<script type="module" src="appthatimports.js"></script>

3. Import files have to be prefixed (./, /, ../ or http:// before)

import * from "./mylib.js"

For more examples, this blog post is good.

A very important distinction, which is easy to miss, is the default bheavior of these two functions, when it comes to exceptions.

I'll use this example to simulate a coroutine that will raise exceptions, sometimes -

import asyncio
import random


async def a_flaky_tsk(i):
    await asyncio.sleep(i)  # bit of fuzz to simulate a real-world example

    if i % 2 == 0:
        print(i, "ok")
    else:
        print(i, "crashed!")
        raise ValueError

coros = [a_flaky_tsk(i) for i in range(10)]

await asyncio.gather(*coros) outputs -

0 ok
1 crashed!
Traceback (most recent call last):
  File "/Users/dev/PycharmProjects/trading/xxx.py", line 20, in <module>
    asyncio.run(main())
  File "/Users/dev/.pyenv/versions/3.8.2/lib/python3.8/asyncio/runners.py", line 43, in run
    return loop.run_until_complete(main)
  File "/Users/dev/.pyenv/versions/3.8.2/lib/python3.8/asyncio/base_events.py", line 616, in run_until_complete
    return future.result()
  File "/Users/dev/PycharmProjects/trading/xxx.py", line 17, in main
    await asyncio.gather(*coros)
  File "/Users/dev/PycharmProjects/trading/xxx.py", line 12, in a_flaky_tsk
    raise ValueError
ValueError

As you can see, the coros after index 1 never got to execute.

But await asyncio.wait(coros) continues to execute tasks, even if some of them fail -

0 ok
1 crashed!
2 ok
3 crashed!
4 ok
5 crashed!
6 ok
7 crashed!
8 ok
9 crashed!

  File "/Users/dev/PycharmProjects/trading/xxx.py", line 12, in a_flaky_tsk
    raise ValueError
ValueError

Ofcourse, this behavior can be changed for both by using -

asyncio.gather(..., return_exceptions=True)

or,

asyncio.wait([...], return_when=asyncio.FIRST_EXCEPTION)

But it doesn't end here!

Notice: Task exception was never retrieved in the logs above.

asyncio.wait() won't re-raise exceptions from the child tasks until you await them individually. (The stacktrace in the logs are just messages, they cannot be caught!)

done, pending = await asyncio.wait(coros)
for tsk in done:
    try:
        await tsk
    except Exception as e:
        print("I caught:", repr(e))

Output -

0 ok
1 crashed!
2 ok
3 crashed!
4 ok
5 crashed!
6 ok
7 crashed!
8 ok
9 crashed!
I caught: ValueError()
I caught: ValueError()
I caught: ValueError()
I caught: ValueError()
I caught: ValueError()

On the other hand, to catch exceptions with asyncio.gather(), you must -

results = await asyncio.gather(*coros, return_exceptions=True)
for result_or_exc in results:
    if isinstance(result_or_exc, Exception):
        print("I caught:", repr(result_or_exc))

(Same output as before)

if you give a 2D array to the plot function of matplotlib it will assume the columns to be lines:

If x and/or y is 2-dimensional, then the corresponding columns will be plotted.

In your case your shape is not accepted (100, 1, 1, 8000). As so you can using numpy squeeze to solve the problem quickly:

np.squeez doc: Remove single-dimensional entries from the shape of an array.

import numpy as np
import matplotlib.pyplot as plt

data = np.random.randint(3, 7, (10, 1, 1, 80))
newdata = np.squeeze(data) # Shape is now: (10, 80)
plt.plot(newdata) # plotting by columns
plt.show()

But notice that 100 sets of 80 000 points is a lot of data for matplotlib. I would recommend that you look for an alternative. The result of the code example (run in Jupyter) is:

I was getting the same exception, whenever a page was getting loaded,

NFO: Error parsing HTTP request header
 Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.
java.lang.IllegalArgumentException: Invalid character found in method name. HTTP method names must be tokens
    at org.apache.coyote.http11.InternalInputBuffer.parseRequestLine(InternalInputBuffer.java:139)

    at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61)
    at java.lang.Thread.run(Thread.java:748)

I found that one of my page URL was https instead of http, when I changed the same, error was gone.

The most simple and the correct way is to use Record type Record<string, string>

const myVar : Record<string, string> = {
   key1: 'val1',
   key2: 'val2',
}

Another way to add that I used to 'hack' this solution was to do this: I set up a seperate computed value that would simply return the nested object value.

data : function(){
    return {
        my_object : {
            my_deep_object : {
                my_value : "hello world";
            }.
        },
    };
},
computed : {
    helper_name : function(){
        return this.my_object.my_deep_object.my_value;
    },
},
watch : {
    helper_name : function(newVal, oldVal){
        // do this...
    }
}

You can plot several columns at once by supplying a list of column names to the plot's y argument.

df.plot(x="X", y=["A", "B", "C"], kind="bar")

This will produce a graph where bars are sitting next to each other.

In order to have them overlapping, you would need to call plot several times, and supplying the axes to plot to as an argument ax to the plot.

import pandas as pd
import matplotlib.pyplot as plt
import numpy as np

y = np.random.rand(10,4)
y[:,0]= np.arange(10)
df = pd.DataFrame(y, columns=["X", "A", "B", "C"])

ax = df.plot(x="X", y="A", kind="bar")
df.plot(x="X", y="B", kind="bar", ax=ax, color="C2")
df.plot(x="X", y="C", kind="bar", ax=ax, color="C3")

plt.show()

Returning falsy value in the render() function will render nothing. So you can just do

 render() {
    let finalClasses = "" + (this.state.classes || "");
    return !isTimeout && <div>{this.props.children}</div>;
  }

Take a look at the equation you can find that binary cross entropy not only punish those label = 1, predicted =0, but also label = 0, predicted = 1.

However categorical cross entropy only punish those label = 1 but predicted = 1.That's why we make assumption that there is only ONE label positive.

Use : instead of =

see the example below that gives an error

app.post('/mews', (req, res) => {
if (isValidMew(req.body)) {
    // insert into db
    const mew = {
        name = filter.clean(req.body.name.toString()),
        content = filter.clean(req.body.content.toString()),
        created: new Date()
    };

That gives Syntex Error: invalid shorthand proprty initializer.

Then i replace = with : that's solve this error.

app.post('/mews', (req, res) => {
if (isValidMew(req.body)) {
    // insert into db
    const mew = {
        name: filter.clean(req.body.name.toString()),
        content: filter.clean(req.body.content.toString()),
        created: new Date()
    };

For those who want to target an iPad Pro 11" the device-width is 834px, device-height is 1194px and the device-pixel-ratio is 2. Source: screen.width, screen.height and devicePixelRatio reported by Safari on iOS Simulator.

Exact media query for portrait: (device-height: 1194px) and (device-width: 834px) and (-webkit-device-pixel-ratio: 2) and (orientation: portrait)

Try to bypass CORS:

For Chrome: edit shortcut or with cmd: C:\Chrome.exe --disable-web-security

For Firefox: Open Firefox and type about:config into the URL bar. search for: security.fileuri.strict_origin_policy set to false

If you disable the maintain aspect ratio in options then it uses the available height:

var chart = new Chart('blabla', {
                type: 'bar',
                data: {
                },
                options: {
                    maintainAspectRatio: false,
                }
            });

You need to stringify the json, not calling toString

var buf = Buffer.from(JSON.stringify(obj));

And for converting string to json obj :

var temp = JSON.parse(buf.toString());

It's very simple javascript code to trigger a download for the user:

window.open("<insert URL here>")

You don't want/need axios for this operation; it should be standard to just let the browser do it's thing.

Note: If you need authorisation for the download then this might not work. I'm pretty sure you can use cookies to authorise a request like this, provided it's within the same domain, but regardless, this might not work immediately in such a case.

As for whether it's possible... not with the in-built file downloading mechanism, no.

One of the Related posts gave me the (simple) answer.

Apparently the auto value on the grid-template-rows property does exactly what I was looking for.

.grid {
    display:grid;
    grid-template-columns: 1fr 1.5fr 1fr;
    grid-template-rows: auto auto 1fr 1fr 1fr auto auto;
    grid-gap:10px;
    height: calc(100vh - 10px);
}

ok. I tried the above two ways but it didnt work for me. After trial and error i came to know that actually the file was not getting saved in 'this.state.file' variable.

fileUpload = (e) => {
    let data = e.target.files
    if(e.target.files[0]!=null){
        this.props.UserAction.fileUpload(data[0], this.fallBackMethod)
    }
}

here fileUpload is a different js file which accepts two params like this

export default (file , callback) => {
const formData = new FormData();
formData.append('fileUpload', file);

return dispatch => {
    axios.put(BaseUrl.RestUrl + "ur/url", formData)
        .then(response => {
            callback(response.data);
        }).catch(error => {
         console.log("*****  "+error)
    });
}

}

don't forget to bind method in the constructor. Let me know if you need more help in this.

I was also getting the same issue of breaking constraints in the log, for a viewCircle in the xib. I almost tried everything listed above and nothing was working for me. Then I tried to change the priority of the Height constraint which was breaking in the log(confirmed by adding an identifiers for the constraints on the xib)enter image description here

Whenever you are using require_once() can be use in a file to include another file when you need the called file only a single time in the current file. Here in the example I have an test1.php.

<?php  
echo "today is:".date("Y-m-d");  
?>  

and in another file that I have named test2.php

<?php  
require_once('test1.php');  
require_once('test1.php');  
?>

as you are watching the m requiring the the test1 file twice but the file will include the test1 once and for calling at the second time this will be ignored. And without halting will display the output a single time.

Whenever you are using 'include_once()` can be used in a file to include another file when you need the called file more than once in the current file. Here in the example I have a file named test3.php.

<?php  
echo "today is:".date("Y-m-d");  
?> 

And in another file that I have named test4.php

<?php  
include_once('test3.php');  
include_once('test3.php');  
?>

as you are watching the m including the test3 file will include the file a single time but halt the further execution.

There is a web-based project for this that is relatively early on called Pongo. It requires installing Python and some dependencies, but it should run on Windows.

Simply,

$current_customer = $this->_getSession()->getCustomer();

This returns the customer object, then you can get all the details from this customer object.

The FOR loop worked well, I modified it a tiny bit:

#include<iostream>
using namespace std;
int main ()
{

    int sum = 0;
    int number;
    int numberitems;


    cout << "Enter number of items: \n";
    cin >> numberitems;

    for(int i=0;i<numberitems;i++)
    {
        cout << "Enter number: \n";
        cin >> number; 

        sum=sum+number;

    }
    cout<<"sum is: "<< sum<<endl;
}

HOWEVER, the WHILE loop has got some errors on line 11 (Count was not declared in this scope). What could be the issue? Also, if you would have a solution using DO,WHILE loop it would be wonderful. Thanks

With an OR (||) operation, if any one of the conditions are true, the result is true.

I think you want an AND (&&) operation here.

This works and shows more than 255 characters in the message box.

Sub TestStrLength()
    Dim s As String
    Dim i As Integer

    s = ""
    For i = 1 To 500
        s = s & "1234567890"
    Next i

    MsgBox s
End Sub

The message box truncates the string to 1023 characters, but the string itself can be very large.

I would also recommend that instead of using fixed variables names with numbers (e.g. Var1, Var2, Var3, ... Var255) that you use an array. This is much shorter declaration and easier to use - loops.

Here's an example:

Sub StrArray()
Dim var(256) As Integer
Dim i As Integer
Dim s As String

For i = 1 To 256
    var(i) = i
Next i

s = "Tims_pet_Robot"
For i = 1 To 256
    s = s & " """ & var(i) & """"
Next i

    SecondSub (s)
End Sub

Sub SecondSub(s As String)
    MsgBox "String length = " & Len(s)
End Sub

Updated this to show that a string can be longer than 255 characters and used in a subroutine/function as a parameter that way. This shows that the string length is 1443 characters. The actual limit in VBA is 2GB per string.

Perhaps there is instead a problem with the API that you are using and that has a limit to the string (such as a fixed length string). The issue is not with VBA itself.

Ok, I see the problem is specifically with the Application.OnTime method itself. It is behaving like Excel functions in that they only accept strings that are up to 255 characters in length. VBA procedures and functions though do not have this limit as I have shown. Perhaps then this limit is imposed for any built-in Excel object method.

Update:
changed ...longer than 256 characters... to ...longer than 255 characters...

What seems to be the problem, I just fixed mine in case anyone was wondering - Due to other errors i turned off build automatically, when i created a new project it said R.layout.main had an issue and needed to import R; So naturally as a novice, i did. Then i built manually and it had a problem with main. Try building your program as is, remove import R and it should be fine.

On Firefox 78 use this ("keypress" doesn't work for Escape key):

function keyPress (e)(){
  if (e.key == "Escape"){
     //do something here      
  }
document.addEventListener("keyup", keyPress);

I know this is an old question, but I had the same problem and solved it thanks to this answer.

I use Putty regularly and have never had any problems. I use and have always used public key authentication. Today I could not connect again to my server, without changing any settings.

Then I saw the answer and remembered that I inadvertently ran chmod 777 . in my user's home directory. I connected from somewhere else and simply ran chmod 755 ~. Everything was back to normal instantly, I didn't even have to restart sshd.

I hope I saved some time from someone

That's because the json you're getting is an array of your RootObject class, rather than a single instance, change your DeserialiseObject<RootObject> to be something like DeserialiseObject<RootObject[]> (un-tested).

You'll then have to either change your method to return a collection of RootObject or do some further processing on the deserialised object to return a single instance.

If you look at a formatted version of the response you provided:

[
   {
      "id":3636,
      "is_default":true,
      "name":"Unit",
      "quantity":1,
      "stock":"100000.00",
      "unit_cost":"0"
   },
   {
      "id":4592,
      "is_default":false,
      "name":"Bundle",
      "quantity":5,
      "stock":"100000.00",
      "unit_cost":"0"
   }
]

You can see two instances in there.

More precisely, add the code below to the private void InitializeComponent() method of the Form class:

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedSingle;

Amazon EBS provides block level storage - It is used to create a filesystem on it and store files. Amazon EFS - its shared storage system similar like NAS/SAN. You need to mount it to unix server and use it. Amazon S3 - It is object based storage where each item is stored with a http URL.

One of the difference is - EBS can be attached to 1 instance at a time and EFS can be attached to multiple instances that why shared storage. S2 plain object storage cannot be mounted.

Similar to brianegge's awk solution, here is the Perl equivalent:

ps | egrep 11383 | perl -lane 'print $F[3]'

-a enables autosplit mode, which populates the @F array with the column data.
Use -F, if your data is comma-delimited, rather than space-delimited.

Field 3 is printed since Perl starts counting from 0 rather than 1

#include<iostream>

using namespace std;

class employee
{
    int idnum;
    double salary;
    public:
        employee(){}

        employee(int a,int b)
        {
            idnum=a;
            salary=b;
        }

        void dis()
        {
            cout<<"1st emp:"<<endl<<"idnum="<<idnum<<endl<<"salary="<<salary<<endl<<endl;
        }

        void operator=(employee &emp)
        {
            idnum=emp.idnum;
            salary=emp.salary;
        }

        void show()
        {
            cout<<"2nd emp:"<<endl<<"idnum="<<idnum<<endl<<"salary="<<salary<<endl;
        }
};

main()
{
    int a;
    double b;

    cout<<"enter id num and salary"<<endl;
    cin>>a>>b;
    employee e1(a,b);
    e1.dis();
    employee e2;
    e2=e1;
    e2.show();  
}

This will build and install both gtest and gmock 1.7.0:

mkdir /tmp/googleTestMock
tar -xvf googletest-release-1.7.0.tar.gz -C /tmp/googleTestMock
tar -xvf googlemock-release-1.7.0.tar.gz -C /tmp/googleTestMock
cd /tmp/googleTestMock
mv googletest-release-1.7.0 gtest
cd googlemock-release-1.7.0
cmake -DBUILD_SHARED_LIBS=ON .
make -j$(nproc)
sudo cp -a include/gmock /usr/include

sudo cp -a ../gtest/include/gtest /usr/include
sudo cp -a gtest/libgtest.so gtest/libgtest_main.so /usr/lib/
sudo ldconfig

This works as well by adding .getWindow().setLayout(width, height) after show()

alertDialogBuilder
            .setMessage("Click yes to exit!")
            .setCancelable(false)
            .setPositiveButton("Yes",new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog,int id) {
                    // if this button is clicked, close
                    // current activity
                    MainActivity.this.finish();
                }
              })
            .setNegativeButton("No",new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog,int id) {
                    // if this button is clicked, just close
                    // the dialog box and do nothing
                    dialog.cancel();
                }
            }).show().getWindow().setLayout(600,500);

Please use @CrossOrigin on the backendside in Spring boot controller (either class level or method level) as the solution for Chrome error 'No 'Access-Control-Allow-Origin' header is present on the requested resource.'

This solution is working for me 100% ...

Example : Class level

@CrossOrigin
@Controller
public class UploadController {

----- OR -------

Example : Method level

@CrossOrigin(origins = "http://localhost:3000", maxAge = 3600)
@RequestMapping(value = "/loadAllCars")
    @ResponseBody
    public List<Car> loadAllCars() {

is it possible to export without looping through all records

For a range in Excel with a large number of rows you may see some performance improvement if you create an Access.Application object in Excel and then use it to import the Excel data into Access. The code below is in a VBA module in the same Excel document that contains the following test data

Option Explicit

Sub AccImport()
    Dim acc As New Access.Application
    acc.OpenCurrentDatabase "C:\Users\Public\Database1.accdb"
    acc.DoCmd.TransferSpreadsheet _
            TransferType:=acImport, _
            SpreadSheetType:=acSpreadsheetTypeExcel12Xml, _
            TableName:="tblExcelImport", _
            Filename:=Application.ActiveWorkbook.FullName, _
            HasFieldNames:=True, _
            Range:="Folio_Data_original$A1:B10"
    acc.CloseCurrentDatabase
    acc.Quit
    Set acc = Nothing
End Sub

Thus far, the only way to "listen" on DOM events, like inserting or modifying Elements, was to use the such called Mutation Events. For instance

document.body.addEventListener('DOMNodeInserted', function( event ) {
    console.log('whoot! a new Element was inserted, see my event object for details!');
}, false);

Further reading on that: MDN

The Problem with Mutation Events was (is) they never really made their way into any official spec because of inconcistencies and stuff. After a while, this events were implemented in all modern browser, but they were declared as deprecated, in other words you don't want to use them.

The official replacement for the Mutation Events is the MutationObserver() object.

Further reading on that: MDN

The syntax at present looks like

var observer = new MutationObserver(function( mutations ) {
    mutations.forEach(function( mutation ) {
         console.log( mutation.type );
    }); 
});

var config = { childList: true };

observer.observe( document.body, config );

At this time, the API has been implemented in newer Firefox, Chrome and Safari versions. I'm not sure about IE and Opera. So the tradeoff here is definitely that you can only target for topnotch browsers.

First of all, you need to move to the location of the file you are trying to execute, so in a Terminal:

cd ~/Documents/python

Now, you should be able to execute your file:

python gameover.py

with pages as (
    SELECT object_id, SUM (reserved_page_count) as reserved_pages, SUM (used_page_count) as used_pages,
            SUM (case 
                    when (index_id < 2) then (in_row_data_page_count + lob_used_page_count + row_overflow_used_page_count)
                    else lob_used_page_count + row_overflow_used_page_count
                 end) as pages
    FROM sys.dm_db_partition_stats
    group by object_id
), extra as (
    SELECT p.object_id, sum(reserved_page_count) as reserved_pages, sum(used_page_count) as used_pages
    FROM sys.dm_db_partition_stats p, sys.internal_tables it
    WHERE it.internal_type IN (202,204,211,212,213,214,215,216) AND p.object_id = it.object_id
    group by p.object_id
)
SELECT object_schema_name(p.object_id) + '.' + object_name(p.object_id) as TableName, (p.reserved_pages + isnull(e.reserved_pages, 0)) * 8 as reserved_kb,
        pages * 8 as data_kb,
        (CASE WHEN p.used_pages + isnull(e.used_pages, 0) > pages THEN (p.used_pages + isnull(e.used_pages, 0) - pages) ELSE 0 END) * 8 as index_kb,
        (CASE WHEN p.reserved_pages + isnull(e.reserved_pages, 0) > p.used_pages + isnull(e.used_pages, 0) THEN (p.reserved_pages + isnull(e.reserved_pages, 0) - p.used_pages + isnull(e.used_pages, 0)) else 0 end) * 8 as unused_kb
from pages p
left outer join extra e on p.object_id = e.object_id

Takes into account internal tables, such as those used for XML storage.

Edit: If you divide the data_kb and index_kb values by 1024.0, you will get the numbers you see in the GUI.

In terms of functionality these are all the same, the difference between them is in code readability and style (which is important to consider)

Use prop() instead of attr() to set the value of checked. Also use :checkbox in find method instead of input and be specific.

Live Demo

$("#news_list tr").click(function() {
    var ele = $(this).find('input');
    if(ele.is(':checked')){
        ele.prop('checked', false);
        $(this).removeClass('admin_checked');
    }else{
        ele.prop('checked', true);
        $(this).addClass('admin_checked');
    }
});

Use prop instead of attr for properties like checked

As of jQuery 1.6, the .attr() method returns undefined for attributes that have not been set. To retrieve and change DOM properties such as the checked, selected, or disabled state of form elements, use the .prop() method

JSON.stringify turns a JavaScript object into JSON text and stores that JSON text in a string, eg:

var my_object = { key_1: "some text", key_2: true, key_3: 5 };

var object_as_string = JSON.stringify(my_object);  
// "{"key_1":"some text","key_2":true,"key_3":5}"  

typeof(object_as_string);  
// "string"  

JSON.parse turns a string of JSON text into a JavaScript object, eg:

var object_as_string_as_object = JSON.parse(object_as_string);  
// {key_1: "some text", key_2: true, key_3: 5} 

typeof(object_as_string_as_object);  
// "object" 

There is also array_pad. You can use it like this:

$data = array_pad($data,$number_of_items,0);

For initializing with zeros the $number_of_items positions of the array $data.

When you correct the measurements - as mentioned above: Any and Exists, and adding average - we'll get following output:

Executing search Exists() 1000 times ... 
Average Exists(): 35566,023
Fastest Exists() execution: 32226 

Executing search Any() 1000 times ... 
Average Any(): 58852,435
Fastest Any() execution: 52269 ticks

Benchmark finished. Press any key.

This seems to be answered - #include <fstream>.

The message means :-

incomplete type - the class has not been defined with a full class. The compiler has seen statements such as class ifstream; which allow it to understand that a class exists, but does not know how much memory the class takes up.

The forward declaration allows the compiler to make more sense of :-

void BindInput( ifstream & inputChannel ); 

It understands the class exists, and can send pointers and references through code without being able to create the class, see any data within the class, or call any methods of the class.

The has initializer seems a bit extraneous, but is saying that the incomplete object is being created.

Check if the RAM configured in HAX installation is equal or lower than your AVD RAM (How to fix: "HAX is not working and emulator runs in emulation mode") that fixed mine.

In my case, there were two different 'AWS_SECRET_ACCESS_KEY' and 'AWS_ACCESS_KEY_ID' values set one through the Windows environment variable and one through the command line.

So, update these two and the default_region using a command line

> aws configure

Press enter and follow the steps to fill the correct AWS_ACESS_KEY_ID AWS_SECRET_ACCESS_KEY and AWS_DEFAULT_REGION

> aws sts get-caller-identity

should return the new set credentials

On ubuntu, i think I was missing the compiler. Fixed with:

sudo apt install build-essential

As this rightly stated

__proto__ is the actual object that is used in the lookup chain to resolve methods, etc. prototype is the object that is used to build __proto__ when you create an object with new:

( new Foo ).__proto__ === Foo.prototype;
( new Foo ).prototype === undefined;

We can further note that __proto__ property of an object created using function constructor points towards the memory location pointed towards by prototype property of that respective constructor.

If we change the memory location of prototype of constructor function, __proto__ of derived object will still continue to point towards the original address space. Therefore to make common property available down the inheritance chain, always append property to constructor function prototype, instead of re-initializing it (which would change its memory address).

Consider the following example:

function Human(){
    this.speed = 25;
}

var himansh = new Human();

Human.prototype.showSpeed = function(){
    return this.speed;
}

himansh.__proto__ === Human.prototype;  //true
himansh.showSpeed();    //25

//now re-initialzing the Human.prototype aka changing its memory location
Human.prototype = {lhs: 2, rhs:3}

//himansh.__proto__ will still continue to point towards the same original memory location. 

himansh.__proto__ === Human.prototype;  //false
himansh.showSpeed();    //25

I don't quote understand what you are trying to achieve, but you need an event listener. Something like:

$('#type').change(function() {
   alert('Value changed to ' + $(this).attr('value'));
});

This will give you the value of the selected option tag.

list multiplication works.

>>> [0] * 10
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

I wrote some Applescript which prompts for a password via a dialog box and then builds a custom bash command, like this:

echo <password> | sudo -S <command>

I'm not sure if this helps.

It'd be nice if sudo accepted a pre-encrypted password, so I could encrypt it within my script and not worry about echoing clear text passwords around. However this works for me and my situation.

Javascript will do the trick here.

function load() {
    var file = new XMLHttpRequest();
    file.open("GET", "http://remote.tld/random.txt", true);
    file.onreadystatechange = function() {
      if (file.readyState === 4) {  // Makes sure the document is ready to parse
        if (file.status === 200) {  // Makes sure it's found the file
          text = file.responseText;
          document.getElementById("div1").innerHTML = text;
        }
      }
    }
}

window.onLoad = load();

I agree with NilObject, but I'd like to add to this:

if you find yourself copying an entire method and only changing a small piece of the code, you can consider tackling it with inversion of control

If you find yourself copying and pasting code around, you're almost always doing something wrong. Codified as the design principle Once and Only Once.

In order to completely set the background to a given color :

1) set first the background color

2) call method "Clear(0,0,this.getWidth(),this.getHeight())" (width and height of the component paint area)

I think it is the basic procedure to set the background... I've had the same problem.

Another usefull hint : if you want to draw BUT NOT in a specific zone (something like a mask or a "hole"), call the setClip() method of the graphics with the "hole" shape (any shape) and then call the Clear() method (background should previously be set to the "hole" color).

You can make more complicated clip zones by calling method clip() (any times you want) AFTER calling method setClip() to have intersections of clipping shapes.

I didn't find any method for unions or inversions of clip zones, only intersections, too bad...

Hope it helps

Add to your ~/.bashrc:

pyclean () {
        find . -type f -name "*.py[co]" -delete
        find . -type d -name "__pycache__" -delete
}

This removes all .pyc and .pyo files, and __pycache__ directories. It's also very fast.

Usage is simply:

$ cd /path/to/directory
$ pyclean

My version of array-based join for string concat:

var c = []; //c stands for content
c.push("<div id='thisDiv' style='left:10px'></div>");
c.push("<div onclick='showDo(\'something\');'></div>");
$(body).append(c.join('\n'));

This has worked well for me, especially as I often insert values into the html constructed this way. But it has lots of limitations. Indentation would be nice. Not having to deal with nested quotation marks would be really nice, and just the bulkyness of it bothers me.

Is the .push() to add to the array taking up a lot of time? See this related answer:

(Is there a reason JavaScript developers don't use Array.push()?)

After looking at these (opposing) test runs, it looks like .push() is fine for string arrays which will not likely grow over 100 items - I will avoid it in favor of indexed adds for larger arrays.

For those who find this topic much later:

If you have just three values to compare there is no significant difference. But if you have to find min of, say, thirty or sixty values, "min" could be easier for anyone to read in the code next year:

int smallest;

smallest = min(a1, a2);
smallest = min(smallest, a3);
smallest = min(smallest, a4);
...
smallest = min(smallest, a37);

But if you think of speed, maybe better way would be to put values into list, and then find min of that:

List<Integer> mySet = Arrays.asList(a1, a2, a3, ..., a37);

int smallest = Collections.min(mySet);

Would you agree?

As you will already be aware, multiple inheritance of classes in Java is not possible, but it's possible with interfaces. You may also want to consider using the composition design pattern.

I wrote a very comprehensive article on composition a few years ago...

https://codereview.stackexchange.com/questions/14542/multiple-inheritance-and-composition-with-java-and-c-updated

You can't: It's a security feature in all modern browsers.

For IE8, it's off by default, but can be reactivated using a security setting:

When a file is selected by using the input type=file object, the value of the value property depends on the value of the "Include local directory path when uploading files to a server" security setting for the security zone used to display the Web page containing the input object.

The fully qualified filename of the selected file is returned only when this setting is enabled. When the setting is disabled, Internet Explorer 8 replaces the local drive and directory path with the string C:\fakepath\ in order to prevent inappropriate information disclosure.

In all other current mainstream browsers I know of, it is also turned off. The file name is the best you can get.

More detailed info and good links in this question. It refers to getting the value server-side, but the issue is the same in JavaScript before the form's submission.

There are extra square brackets in the command you tried.

To install the latest version from the v1 branch, you can use:

npm install git://github.com/shakacode/bootstrap-loader.git#v1 --save

Actually this is not a duplicate question. And this how i solve my problem after several times :

   int offset = DateTimeZone.forID("anytimezone").getOffset(new DateTime());

This is the way to get offset from desired timezone.

Let's return to our code, we were getting timestamp from a result set of query, and using it with timezone to create our datetime.

   DateTime dt = new DateTime(rs.getTimestamp("anytimestampcolumn"),
                         DateTimeZone.forID("anytimezone"));

Now we will add our offset to the datetime, and get the timestamp from it.

    dt = dt.plusMillis(offset);
    Timestamp ts = new Timestamp(dt.getMillis());

May be this is not the actual way to get it, but it solves my case. I hope it helps anyone who is stuck here.

Eventhough there are several methods, The best way (most efficient and easiest) is using db.dropDatabase()

What I did based on the other answers was

NEWLINE=$'\n'
my_var="__between eggs and bacon__"
echo "spam${NEWLINE}eggs${my_var}bacon${NEWLINE}knight"

# which outputs:
spam
eggs__between eggs and bacon__bacon
knight

I can confirm this is a terminfo issue. This is what worked for me. SSH in to the remote machine and run

 sudo apt-get install ncurses-term

Boom. Problem solved.

Policykit is a system daemon and policykit authentication agent is used to verify identity of the user before executing actions. The messages logged in /var/log/secure show that an authentication agent is registered when user logs in and it gets unregistered when user logs out. These messages are harmless and can be safely ignored.

Alternatively to usleep(), which is not defined in POSIX 2008 (though it was defined up to POSIX 2004, and it is evidently available on Linux and other platforms with a history of POSIX compliance), the POSIX 2008 standard defines nanosleep():

nanosleep - high resolution sleep

#include <time.h>
int nanosleep(const struct timespec *rqtp, struct timespec *rmtp);

The nanosleep() function shall cause the current thread to be suspended from execution until either the time interval specified by the rqtp argument has elapsed or a signal is delivered to the calling thread, and its action is to invoke a signal-catching function or to terminate the process. The suspension time may be longer than requested because the argument value is rounded up to an integer multiple of the sleep resolution or because of the scheduling of other activity by the system. But, except for the case of being interrupted by a signal, the suspension time shall not be less than the time specified by rqtp, as measured by the system clock CLOCK_REALTIME.

The use of the nanosleep() function has no effect on the action or blockage of any signal.

Save the following code to a file, for example, named stash. Usage is stash <filename_regex>. The argument is the regular expression for the full path of the file. For example, to stash a/b/c.txt, stash a/b/c.txt or stash .*/c.txt, etc.

$ chmod +x stash
$ stash .*.xml
$ stash xyz.xml

Code to copy into the file:

#! /usr/bin/expect --
log_user 0
set filename_regexp [lindex $argv 0]

spawn git stash -p

for {} 1 {} {
  expect {
    -re "diff --git a/($filename_regexp) " {
      set filename $expect_out(1,string)
    }
    "diff --git a/" {
      set filename ""
    }
    "Stash this hunk " {
      if {$filename == ""} {
        send "n\n"
      } else {
        send "a\n"
        send_user "$filename\n"
      }
    }
    "Stash deletion " {
      send "n\n"
    }
    eof {
      exit
    }
  }
}

The condition below:

//Element[@attribute1="abc" and @attribute2="xyz" and Data]

checks for the existence of the element Data within Element and not for element value Data.

Instead you can use

//Element[@attribute1="abc" and @attribute2="xyz" and text()="Data"]

wget from a linux box might also be a good option as there are switches to spider and change it's output.

EDIT: wget is also available on Windows: http://gnuwin32.sourceforge.net/packages/wget.htm

You can also create a request instance with default options:

require('request').defaults({ rejectUnauthorized: false })

On a recent project we had the challenge of working with and manipulating a large collection of data. Our client provided us with a 50 CSV files ranging from 30 MB to 350 MB in size and all in all containing approximately 20 million rows of data and 15 columns of data. Our end goal was to import and manipulate the data into a MySQL relational database to be used to power a front-end PHP script that we also developed. Now, working with a dataset this large or larger is not the simplest of tasks and in working on it we wanted to take a moment to share some of the things you should consider and know when working with large datasets like this.

1. Analyze Your Dataset Pre-Import

   I can’t stress this first step enough! Make sure that you take the time to analyze the data you are working with before importing it at all. Getting an understand of what all of the data represents, what columns related to what and what type of manipulation you need to will end up saving you time in the long run.

2. LOAD DATA INFILE is Your Friend

   Importing large data files like the ones we worked with (and larger ones) can be tough to do if you go ahead and try a regular CSV insert via a tool like PHPMyAdmin. Not only will it fail in many cases because your server won’t be able to handle a file upload as large as some of your data files due to upload size restrictions and server timeouts, but even if it does succeed, the process could take hours depending our your hardware. The SQL function LOAD DATA INFILE was created to handle these large datasets and will significantly reduce the time it takes to handle the import process. Of note, this can be executed through PHPMyAdmin, but you may still have file upload issues. In that case you can upload the files manually to your server and then execute from PHPMyAdmin (see their manual for more info) or execute the command via your SSH console (assuming you have your own server)

   LOAD DATA INFILE '/mylargefile.csv' INTO TABLE temp_data FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n'
   

3. MYISAM vs InnoDB

   Large or small database it’s always good to take a little time to consider which database engine you are going to use for your project. The two main engines you are going to read about are MYISAM and InnoDB and each has their own benefits and drawbacks. In brief the things to consider (in general) are as follows:

   MYISAM

   • Lower Memory Usage
   • Allows for Full-Text Searching
   • Table Level Locking – Locks Entire Table on Write
   • Great for Read-Intensive Applications

   InnoDB

   • List item
   • Uses More Memory
   • No Full-Text Search Support
   • Faster Performance
   • Row Level Locking – Locks Single Row on Write
   • Great for Read/Write Intensive Applications

4. Plan Your Design Carefully

   MySQL AnalyzeYour databases design/structure is going to be a large factor in how it performs. Take your time when it comes to planning out the different fields and analyze the data to figure out what the best field types, defaults and field length. You want to accommodate for the right amounts of data and try to avoid varchar columns and overly large data types when the data doesn’t warrant it. As an additional step after you are done with your database, you make want to see what MySQL suggests as field types for all of your different fields. You can do this by executing the following SQL command:

   ANALYZE TABLE my_big_table
   

   The result will be a description of each columns information along with a recommendation for what type of datatype it should be along with a proper length. Now you don’t necessarily need to follow the recommendations as they are based solely on existing data, but it may help put you on the right track and get you thinking

5. To Index or Not to Index

   For a dataset as large as this it’s infinitely important to create proper indexes on your data based off of what you need to do with the data on the front-end, BUT if you plan to manipulate the data beforehand refrain from placing too many indexes on the data. Not only will it will make your SQL table larger, but it will also slow down certain operations like column additions, subtractions and additional indexing. With our dataset we needed to take the information we just imported and break it into several different tables to create a relational structure as well as take certain columns and split the information into additional columns. We placed an index on the bare minimum of columns that we knew would help us with the manipulation. All in all, we took 1 large table consisting of 20 million rows of data and split its information into 6 different tables with pieces of the main data in them along with newly created data based off the existing content. We did all of this by writing small PHP scripts to parse and move the data around.

6. Finding a Balance

   A big part of working with large databases from a programming perspective is speed and efficiency. Getting all of the data into your database is great, but if the script you write to access the data is slow, what’s the point? When working with large datasets it’s extremely important that you take the time to understand all of the queries that your script is performing and to create indexes to help those queries where possible. One such way to analyze what your queries are doing is by executing the following SQL command:

   EXPLAIN SELECT some_field FROM my_big_table WHERE another_field='MyCustomField';
   

   By adding EXPLAIN to the start of your query MySQL will spit out information describing what indexes it tried to use, did use and how it used them. I labeled this point ‘Finding a balance’ because although indexes can help your script perform faster, they can just as easily make it run slower. You need to make sure you index what is needed and only what is needed. Every index consumes disk space and adds to the overhead of the table. Every time you make an edit to your table, you have to rebuild the index for that particular row and the more indexes you have on those rows, the longer it will take. It all comes down to making smart indexes, efficient SQL queries and most importantly benchmarking as you go to understand what each of your queries is doing and how long it’s taking to do it.

7. Index On, Index Off

   As we worked on the database and front-end script, both the client and us started to notice little things that needed changing and that required us to make changes to the database. Some of these changes involved adding/removing columns and changing the column types. As we had already setup a number of indexes on the data, making any of these changes required the server to do some serious work to keep the indexes in place and handle any modifications. On our small VPS server, some of the changes were taking upwards of 6 hours to complete…certainly not helpful to us being able to do speedy development. The solution? Turn off indexes! Sometimes it’s better to turn the indexes off, make your changes and then turn the indexes back on….especially if you have a lot of different changes to make. With the indexes off, the changes took a matter of seconds to minutes versus hours. When we were happy with our changes we simply turned our indexes back on. This of course took quite some time to re-index everything, but it was at least able to re-index everything all at once, reducing the overall time needed to make these changes one by one. Here’s how to do it:

   • Disable Indexes: ALTER TABLE my_big_table DISABLE KEY
   • Enable Indexes: ALTER TABLE my_big_table ENABLE KEY

8. Give MySQL a Tune-Up

   Don’t neglect your server when it comes to making your database and script run quickly. Your hardware needs just as much attention and tuning as your database and script does. In particular it’s important to look at your MySQL configuration file to see what changes you can make to better enhance its performance. A great little tool that we’ve come across is the MySQL Tuner http://mysqltuner.com/ . It’s a quick little Perl script that you can download right to your server and run via SSH to see what changes you might want to make to your configuration. Note that you should actively use your front-end script and database for several days before running the tuner so that the tuner has data to analyze. Running it on a fresh server will only provide minimal information and tuning options. We found it great to use the tuner script every few days for the two weeks to see what recommendations it would come up with and at the end we had significantly increased the databases performance.

9. Don’t be Afraid to Ask

   Working with SQL can be challenging to begin with and working with extremely large datasets only makes it that much harder. Don’t be afraid to go to professionals who know what they are doing when it comes to large datasets. Ultimately you will end up with a superior product, quicker development and quicker front-end performance. When it comes to large databases sometimes it’s take a professionals experienced eyes to find all the little caveats that could be slowing your databases performance.

Check /var/lib/php/session and its permissions. This dir should be writable by user so the session can be stored

I foolishly uncommented the default config, which has passwords like "". Tomcat fails to parse this file (becayse of the "<"), and then whatever other config you add won't work-

That’s a typo. You’ve accidently set user.mail with no e. Fix it by setting user.email in the global configuration with

git config --global user.email "[email protected]"

Use setDate

.datepicker( "setDate" , date )

Sets the current date for the datepicker. The new date may be a Date object or a string in the current date format (e.g. '01/26/2009'), a number of days from today (e.g. +7) or a string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '+1m +7d'), or null to clear the selected date.

string filePath = HttpContext.Current.Server.MapPath("~/folderName/filename.extension");

OR

string filePath = HttpContext.Server.MapPath("~/folderName/filename.extension");

GPS will be used if the user has allowed it to be used in its settings.

You can't explicitly switch this on anymore, but you don't have to - it's a privacy setting really, so you don't want to tweak it. If the user is OK with apps getting precise co-ordinates it'll be on. Then the location manager API will use GPS if it can.

If your app really isn't useful without GPS, and it's off, you can open the settings app at the right screen using an intent so the user can enable it.

Text printed to stderr will show up in httpd's error log when running under mod_wsgi. You can either use print directly, or use logging instead.

I had same problem with Spring Boot 2.1.1 and JUnit 4
just added those annotations:

@RunWith( SpringRunner.class )
@SpringBootTest

and all went well.

For Junit 5:

See ?merge:

the name "row.names" or the number 0 specifies the row names.

Example:

R> de <- merge(d, e, by=0, all=TRUE)  # merge by row names (by=0 or by="row.names")
R> de[is.na(de)] <- 0                 # replace NA values
R> de
  Row.names   a   b   c   d   e   f   g   h   i  j  k  l  m  n  o  p  q  r  s

Adding allowfullscreen="allowfullscreen" and altering the type of YouTube embed fixed my issue.

You can use the getClass() method, or you can use instanceof. For example

for (Object obj : list) {
  if (obj instanceof String) {
   ...
  }
}

or

for (Object obj : list) {
 if (obj.getClass().equals(String.class)) {
   ...
 }
}

Note that instanceof will match subclasses. For instance, of C is a subclass of A, then the following will be true:

C c = new C();
assert c instanceof A;

However, the following will be false:

C c = new C();
assert !c.getClass().equals(A.class)

In my case checking the check-box

"Copy project into workspace"

did the trick.

I've got this error when I ran composer install inside my PHP DOCKER container, It's a memory issue. Solved by increasing SWAP memory in DOCKER PREFERENCES from 512MB to 1.5GB

After you start the Redis-server using:service redis-server start --port 8000 or redis-server.

Use redis-cli -p 8000 to connect to the server as a client in a different terminal.

You can use either

1. FLUSHDB - Delete all the keys of the currently selected DB. This command never fails. The time-complexity for this operation is O(N), N being the number of keys in the database.
2. FLUSHALL - Delete all the keys of all the existing databases, not just the currently selected one. This command never fails. The time-complexity for this operation is O(N), N being the number of keys in all existing databases.

Check the documentation for ASYNC option for both.

If you are using Redis through its python interface, use these two functions for the same functionality:

def flushall(self):
    "Delete all keys in all databases on the current host"
    return self.execute_command('FLUSHALL')

and

def flushdb(self):
    "Delete all keys in the current database"
    return self.execute_command('FLUSHDB')

I've always used singular simply because that's what I was taught. However, while creating a new schema recently, for the first time in a long time, I actively decided to maintain this convention simply because... it's shorter. Adding an 's' to the end of every table name seems as useless to me as adding 'tbl_' in front of every one.

If you're using Windows, the unix-style default path of ssh-keygen is at fault.

In Line 2 it says Enter file in which to save the key (/c/Users/Eva/.ssh/id_rsa):. That full filename in the parantheses is the default, obviously Windows cannot access a file like that. If you type the Windows equivalent (c:\Users\Eva\.ssh\id_rsa), it should work.

Before running this, you also need to create the folder. You can do this by running mkdir c:\Users\Eva\.ssh, or by created the folder ".ssh." from File Explorer (note the second dot at the end, which will get removed automatically, and is required to create a folder that has a dot at the beginning).

c:\Users\Administrator\.ssh>ssh-keygen -t rsa -C "[email protected]"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/Administrator/.ssh/id_rsa): C:\Users\Administrator\.ssh\id_rsa
Enter passphrase (empty for no passphrase):
Enter same passphrase again:

I know this is an old thread, but I thought the answer might help others.

The validate_required function seems to expect an HTML form control (e.g, text input field) as first argument, and check whether there is a value there at all. That is not what you want in this case.

Also, when you write ['password'].value, you create a new array of length one, containing the string 'password', and then read the non-existing property "value" from it, yielding the undefined value.

What you may want to try instead is:

if (password.value != cpassword.value) { cpassword.focus(); return false; }

(You also need to write the error message somehow, but I can't see from your code how that is done.).

sounds like the 'first line' you're talking of is your table-header - so you realy should think of using thead and tbody in your markup (click here) which would result in 'better' markup (semantically correct, useful for things like screenreaders) and easier, cross-browser-friendly possibilitys for css-selection (table thead ... { ... })

Use Link-1 to generate a project. this a basic project for learning. you can understand the folder structure. Use Link-2 for creating a basic Spring boot project. 1: http://start.spring.io/ 2: https://projects.spring.io/spring-boot/

Create a gradle/maven project Automatically src/main/java and src/main/test will be created. create controller/service/Repository package and start writing the code.

It's a known fact that, on average, people can keep 7 +/- 2 things in their head at a time. I like to use that principle with parameters. Assuming that programmers are all above-average intelligent people, I'd say everything 10+ is too many.

BTW, if parameters are similar in any way, I'd put them in a vector or list rather than a struct or class.

Use this code for read file with all type of extension file.

string[] sDirectoryInfo = Directory.GetFiles(SourcePath, "*.*");

Because & has a lesser priority than ==.

Your code is equivalent to a[0] & (1 == 0), and unless a[0] is a boolean this won't compile...

You need to:

(a[0] & 1) == 0

etc etc.

(yes, Java does hava a boolean & operator -- a non shortcut logical and)

Looks like I'm late to the game, but this is a common question...

This is probably the code you want.

Please note that this code is in the public domain, from Usenet, MSDN, and the Excellerando blog.

Public Function ComputerName() As String
'' Returns the host name

'' Uses late-binding: bad for performance and stability, useful for 
'' code portability. The correct declaration is:

'   Dim objNetwork  As IWshRuntimeLibrary.WshNetwork
'   Set objNetwork = New IWshRuntimeLibrary.WshNetwork

    Dim objNetwork As Object
    Set objNetwork = CreateObject("WScript.Network")

    ComputerName = objNetwork.ComputerName
    
    Set objNetwork = Nothing

End Function

You'll probably need this, too:

Public Function UserName(Optional WithDomain As Boolean = False) As String
'' Returns the user's network name

'' Uses late-binding: bad for performance and stability, useful for
'' code portability. The correct declaration is:

'   Dim objNetwork  As IWshRuntimeLibrary.WshNetwork
'   Set objNetwork = New IWshRuntimeLibrary.WshNetwork


    Dim objNetwork As Object
    Set objNetwork = CreateObject("WScript.Network")

    If WithDomain Then
        UserName = objNetwork.UserDomain & "\" & objNetwork.UserName
    Else
        UserName = objNetwork.UserName
    End If
    
    Set objNetwork = Nothing

End Function

As these answers are old, I found this alternative. It is very clean and works with just java annotations:

To fix it, create a “none static setter” to assign the injected value for the static variable. For example :

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class GlobalValue {

public static String DATABASE;

@Value("${mongodb.db}")
public void setDatabase(String db) {
    DATABASE = db;
}
}

UIImageView *imageView = [UIImageView alloc]init];
imageView.layer.masksToBounds = YES;
imageView.layer.borderColor = [UIColor blackColor].CGColor;
imageView.layer.borderWidth = 1;    

This code can be used for adding UIImageView view border.

For people having a startTime (like 12h:30:30) and a duration (value in minutes like 120), you can guess the endTime like so:

const startTime = '12:30:00';
const durationInMinutes = '120';

const endTime = moment(startTime, 'HH:mm:ss').add(durationInMinutes, 'minutes').format('HH:mm');

// endTime is equal to "14:30"

As of Python 3.4 one can use the pathlib module to solve this.

If you happen to be on an older version, you can use the backported version found here

Let's assume you are not in the root path (just to add a bit of difficulty to it) you want to rename, and have to provide a full path, we can look at this:

some_path = 'a/b/c/the_file.extension'

So, you can take your path and create a Path object out of it:

from pathlib import Path
p = Path(some_path)

Just to provide some information around this object we have now, we can extract things out of it. For example, if for whatever reason we want to rename the file by modifying the filename from the_file to the_file_1, then we can get the filename part:

name_without_extension = p.stem

And still hold the extension in hand as well:

ext = p.suffix

We can perform our modification with a simple string manipulation:

Python 3.6 and greater make use of f-strings!

new_file_name = f"{name_without_extension}_1"

Otherwise:

new_file_name = "{}_{}".format(name_without_extension, 1)

And now we can perform our rename by calling the rename method on the path object we created and appending the ext to complete the proper rename structure we want:

p.rename(Path(p.parent, new_file_name + ext))

More shortly to showcase its simplicity:

Python 3.6+:

from pathlib import Path
p = Path(some_path)
p.rename(Path(p.parent, f"{p.stem}_1_{p.suffix}"))

Versions less than Python 3.6 use the string format method instead:

from pathlib import Path
p = Path(some_path)
p.rename(Path(p.parent, "{}_{}_{}".format(p.stem, 1, p.suffix))

I think these are two really different cases. In the first case memory is allocated and initialized in compile-time. In the second - in runtime.

I am from .net background. However, java/c# are more/less same.

If you instantiate a non-primitive type (array in your case), it won't be null.
e.g. int[] numbers = new int[3];
In this case, the space is allocated & each of the element has a default value of 0.

It will be null, when you don't new it up.
e.g.

int[] numbers = null; // changed as per @Joachim's suggestion.
if (numbers == null)
{
   System.out.println("yes, it is null. Please new it up");
}

SciPy has the function scipy.special.factorial (formerly scipy.misc.factorial)

>>> import math
>>> import scipy.special
>>> math.factorial(6)
720
>>> scipy.special.factorial(6)
array(720.0)

JNZ is short for "Jump if not zero (ZF = 0)", and NOT "Jump if the ZF is set".

If it's any easier to remember, consider that JNZ and JNE (jump if not equal) are equivalent. Therefore, when you're doing cmp al, 47 and the content of AL is equal to 47, the ZF is set, ergo the jump (if Not Equal - JNE) should not be taken.

alloca() is very useful if you can't use a standard local variable because its size would need to be determined at runtime and you can absolutely guarantee that the pointer you get from alloca() will NEVER be used after this function returns.

You can be fairly safe if you

• do not return the pointer, or anything that contains it.
• do not store the pointer in any structure allocated on the heap
• do not let any other thread use the pointer

The real danger comes from the chance that someone else will violate these conditions sometime later. With that in mind it's great for passing buffers to functions that format text into them :)

Your regex ^[0-9] matches anything beginning with a digit, including strings like "1A". To avoid a partial match, append a $ to the end:

^[0-9]*$

This accepts any number of digits, including none. To accept one or more digits, change the * to +. To accept exactly one digit, just remove the *.

UPDATE: You mixed up the arguments to IsMatch. The pattern should be the second argument, not the first:

if (!System.Text.RegularExpressions.Regex.IsMatch(textbox.Text, "^[0-9]*$"))

CAUTION: In JavaScript, \d is equivalent to [0-9], but in .NET, \d by default matches any Unicode decimal digit, including exotic fare like ? (Myanmar 2) and ? (N'Ko 9). Unless your app is prepared to deal with these characters, stick with [0-9] (or supply the RegexOptions.ECMAScript flag).

yourarray.shape or np.shape() or np.ma.shape() returns the shape of your ndarray as a tuple; And you can get the (number of) dimensions of your array using yourarray.ndim or np.ndim(). (i.e. it gives the n of the ndarray since all arrays in NumPy are just n-dimensional arrays (shortly called as ndarrays))

For a 1D array, the shape would be (n,) where n is the number of elements in your array.

For a 2D array, the shape would be (n,m) where n is the number of rows and m is the number of columns in your array.

Please note that in 1D case, the shape would simply be (n, ) instead of what you said as either (1, n) or (n, 1) for row and column vectors respectively.

This is to follow the convention that:

For 1D array, return a shape tuple with only 1 element   (i.e. (n,))
For 2D array, return a shape tuple with only 2 elements (i.e. (n,m))
For 3D array, return a shape tuple with only 3 elements (i.e. (n,m,k))
For 4D array, return a shape tuple with only 4 elements (i.e. (n,m,k,j))

and so on.

Also, please see the example below to see how np.shape() or np.ma.shape() behaves with 1D arrays and scalars:

# sample array
In [10]: u = np.arange(10)

# get its shape
In [11]: np.shape(u)    # u.shape
Out[11]: (10,)

# get array dimension using `np.ndim`
In [12]: np.ndim(u)
Out[12]: 1

In [13]: np.shape(np.mean(u))
Out[13]: ()       # empty tuple (to indicate that a scalar is a 0D array).

# check using `numpy.ndim`
In [14]: np.ndim(np.mean(u))
Out[14]: 0

P.S.: So, the shape tuple is consistent with our understanding of dimensions of space, at least mathematically.

Some of more advanced Oracle database features such as session trace do not work properly in Oracle 11g XE 32-bit if installed on Windows 64-bit system. I needed session trace on Windows 7 64-bit.

Apart from that it works well for me in multiple production MS Windows 64-bit systems: Windows Server 2008 R2 and Windows Server 2003 R2.

To answer your questions directly rather than pointing you at documentation:

1) In order to keep it up to date, do a git pull and that will pull down the latest changes in the repository, on the branch that you're currently using (which is generally master)

2) I don't think there's something (widely available) that'll do this for you. To update them follow 1) for all projects.

As mentioned in the previous posts, using an HttpServletReqiestWrapper is the way to go, however the missed part in those posts was that apart from overriding the method getParameter(), you should also override other parameter related methods to produce a consistent response. e.g. the value of a param added by the custom request wrapper should also be included in the parameters map returned by the method getParameterMap(). Here is an example:

   public class AddableHttpRequest extends HttpServletRequestWrapper {

    /** A map containing additional request params this wrapper adds to the wrapped request */
    private final Map<String, String> params = new HashMap<>();

    /**
     * Constructs a request object wrapping the given request.
     * @throws java.lang.IllegalArgumentException if the request is null
     */
    AddableHttpRequest(final HttpServletRequest request) {
        super(request)
    }

    @Override
    public String getParameter(final String name) {
        // if we added one with the given name, return that one
        if ( params.get( name ) != null ) {
            return params.get( name );
        } else {
            // otherwise return what's in the original request
            return super.getParameter(name);
        }
    }


    /**
     * *** OVERRIDE THE METHODS BELOW TO REFLECT PARAMETERS ADDED BY THIS WRAPPER ****
     */

    @Override
    public Map<String, String> getParameterMap() {
        // defaulf impl, should be overridden for an approprivate map of request params
        return super.getParameterMap();
    }

    @Override
    public Enumeration<String> getParameterNames() {
        // defaulf impl, should be overridden for an approprivate map of request params names
        return super.getParameterNames();
    }

    @Override
    public String[] getParameterValues(final String name) {
        // defaulf impl, should be overridden for an approprivate map of request params values
        return super.getParameterValues(name);
    }
}

This code works well for returning all of the IP addresses that might belong to a particular URI. Since many systems are now in a hosted environment (AWS/Akamai/etc.), systems may return several IP addresses. The lambda was "borrowed" from @Peter Silva.

def get_ips_by_dns_lookup(target, port=None):
    '''
        this function takes the passed target and optional port and does a dns
        lookup. it returns the ips that it finds to the caller.

        :param target:  the URI that you'd like to get the ip address(es) for
        :type target:   string
        :param port:    which port do you want to do the lookup against?
        :type port:     integer
        :returns ips:   all of the discovered ips for the target
        :rtype ips:     list of strings

    '''
    import socket

    if not port:
        port = 443

    return list(map(lambda x: x[4][0], socket.getaddrinfo('{}.'.format(target),port,type=socket.SOCK_STREAM)))

ips = get_ips_by_dns_lookup(target='google.com')

This example uses Bash's built-in getopts command and is from the Google Shell Style Guide:

a_flag=''
b_flag=''
files=''
verbose='false'

print_usage() {
  printf "Usage: ..."
}

while getopts 'abf:v' flag; do
  case "${flag}" in
    a) a_flag='true' ;;
    b) b_flag='true' ;;
    f) files="${OPTARG}" ;;
    v) verbose='true' ;;
    *) print_usage
       exit 1 ;;
  esac
done

Note: If a character is followed by a colon (e.g. f:), that option is expected to have an argument.

Example usage: ./script -v -a -b -f filename

Using getopts has several advantages over the accepted answer:

• the while condition is a lot more readable and shows what the accepted options are
• cleaner code; no counting the number of parameters and shifting
• you can join options (e.g. -a -b -c ? -abc)

However, a big disadvantage is that it doesn't support long options, only single-character options.

Tips from 2020:

From Flask 1.0, it defaults to enable multiple threads (source), you don't need to do anything, just upgrade it with:

$ pip install -U flask

If you are using flask run instead of app.run() with older versions, you can control the threaded behavior with a command option (--with-threads/--without-threads):

$ flask run --with-threads

It's same as app.run(threaded=True)

Had faced same issue ..

well in my case i have saved

google-services.json

as

google_services.json

I tried every solution mentioned above but nothing helps... the error was instead of "_" you need to put "-"(dash).

Just refactoring the file to google-services.json from google_services.json works like charm..

Hope this helps!!!

P.S. I know it's sound silly but this only works for me...

The @Transactional annotation takes a timeout parameter where you can specify timeout in seconds for a specific method in the @RestController

@RequestMapping(value = "/method",
    method = RequestMethod.POST,
    produces = MediaType.APPLICATION_JSON_VALUE)
@Timed
@Transactional(timeout = 120)

SELECT to_char(sysdate + (1/24/60) * 30, 'dd/mm/yy HH24:MI am') from dual;

simply you can use this with various date format....

You may be able to fix this error by name spacing :: the function call

comparison.cloud(colors = c("red", "green"), max.words = 100)

to

wordcloud::comparison.cloud(colors = c("red", "green"), max.words = 100)

npm install serve-index

var express    = require('express')
var serveIndex = require('serve-index')
var path = require('path')
var serveStatic = require('serve-static')
var app = express()
var port = process.env.PORT || 3000;
/**for files */
app.use(serveStatic(path.join(__dirname, 'public')));
/**for directory */
app.use('/', express.static('public'), serveIndex('public', {'icons': true}))

// Listen
app.listen(port,  function () {
  console.log('listening on port:',+ port );
})

/* eslint no-restricted-globals:0 */

is another alternate approach

The uname command (http://developer.apple.com/documentation/Darwin/Reference/ManPages/man1/uname.1.html) with no parameters should tell you the operating system name. I'd use that, then make conditionals based on the return value.

Example

UNAME := $(shell uname)

ifeq ($(UNAME), Linux)
# do something Linux-y
endif
ifeq ($(UNAME), Solaris)
# do something Solaris-y
endif

Try loading your javascript after.

Try this:

<h2>Hello World!</h2>
<p id="myParagraph">This is an example website</p>

<form>
  <input type="text" id="myTextfield" placeholder="Type your name" />
  <input type="submit" id="myButton" value="Go" />
</form>

<script src="js/script.js" type="text/javascript"></script>

You could use CAST or CONVERT:

SELECT CAST(MyVarcharCol AS INT) FROM Table

SELECT CONVERT(INT, MyVarcharCol) FROM Table

You can try

if(combo1.Text == "")
{

}

H2CO3 is right, you can use a makefile with the CXXFLAGS set with -std=c++11 A makefile is a simple text file with instructions about how to compile your program. Create a new file named Makefile (with a capital M). To automatically compile your code just type the make command in a terminal. You may have to install make.

Here's a simple one :

CXX=clang++
CXXFLAGS=-g -std=c++11 -Wall -pedantic
BIN=prog

SRC=$(wildcard *.cpp)
OBJ=$(SRC:%.cpp=%.o)

all: $(OBJ)
    $(CXX) -o $(BIN) $^

%.o: %.c
    $(CXX) $@ -c $<

clean:
    rm -f *.o
    rm $(BIN)

It assumes that all the .cpp files are in the same directory as the makefile. But you can easily tweak your makefile to support a src, include and build directories.

Edit : I modified the default c++ compiler, my version of g++ isn't up-to-date. With clang++ this makefile works fine.

A practical explanation: By default, <p> </p> will add line breaks before and after the enclosed text (so it creates a paragraph). <span> does not do this, that is why it is called inline.

You can do this:

sql = "Select * from ... your sql query here"
records_array = ActiveRecord::Base.connection.execute(sql)

records_array would then be the result of your sql query in an array which you can iterate through.

I come across this problem because the wrong name of my package (scipy-0.17.0-cp27-none-win_amd64 (1)), after I delete the '(1)' and change the package to scipy-0.17.0-cp27-none-win_amd64, the problem got resolved.

The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity changes.

Instead you could try the following approach. Change your markup to the following:

<div ng-controller="myAppController" style="text-align:center">
  <p style="font-size:28px;">Enter Quantity:
      <input type="text" ng-model="quantity"/>
  </p>
  <button ng-click="calculateQuantity()">Calculate</button>
  <h2>Total Cost: Rs.{{quantityResult}}</h2>
</div>

Next, update your controller:

myAppModule.controller('myAppController', function($scope,calculateService) {
  $scope.quantity=1;
  $scope.quantityResult = 0;

  $scope.calculateQuantity = function() {
    $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  };
});

Here's a JSBin example that demonstrates the above approach.

The problem with this approach is the calculated result remains visible with the old value till the button is clicked. To address this, you could hide the result whenever the quantity changes.

This would involve updating the template to add an ng-change on the input, and an ng-if on the result:

<input type="text" ng-change="hideQuantityResult()" ng-model="quantity"/>

and

<h2 ng-if="showQuantityResult">Total Cost: Rs.{{quantityResult}}</h2>

In the controller add:

$scope.showQuantityResult = false;

$scope.calculateQuantity = function() {
  $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  $scope.showQuantityResult = true;
};

$scope.hideQuantityResult = function() {
  $scope.showQuantityResult = false;
}; 

These updates can be seen in this JSBin demo.

Just don't anchor your pattern:

/Test/

The above regex will check for the literal string "Test" being found somewhere within it.

If you need to load a file that's relative to some directory where you already are (like in the current directory), here's an easy solution:

File f;

if (System.getProperty("sun.arch.data.model").equals("32")) {
    // 32-bit JVM
    f = new File("mylibfile32.so");
} else {
    // 64-bit JVM
    f = new File("mylibfile64.so");
}
System.load(f.getAbsolutePath());

Of course it is!

Give them both an id and set up the CSS accordingly:

#table1
{
    CSS for table1
}


#table2
{
    CSS for table2
}

var x = document.getElementById("myTable").rows.length;

MySQL queries are not case-sensitive by default. Following is a simple query that is looking for 'value'. However it will return 'VALUE', 'value', 'VaLuE', etc…

SELECT * FROM `table` WHERE `column` = 'value'

The good news is that if you need to make a case-sensitive query, it is very easy to do using the BINARY operator, which forces a byte by byte comparison:

SELECT * FROM `table` WHERE BINARY `column` = 'value'

If you use Microsoft.ApplicationBlocks.Data it'll make calling your sprocs a single line

SqlHelper.ExecuteNonQuery(ConnectionString, "SprocName", DOB)

Oh and I think casperOne is correct...if you want to ensure the correct datetime over multiple timezones then simply convert the value to UTC before you send the value to SQL Server

SqlHelper.ExecuteNonQuery(ConnectionString, "SprocName", DOB.ToUniversalTime())

Alternative using the pathlib library (often preferred over os.path).

This method avoids iterative use of pandas concat()/apped().

From the pandas documentation:
It is worth noting that concat() (and therefore append()) makes a full copy of the data, and that constantly reusing this function can create a significant performance hit. If you need to use the operation over several datasets, use a list comprehension.

import pandas as pd
from pathlib import Path

dir = Path("../relevant_directory")

df = (pd.read_csv(f) for f in dir.glob("*.csv"))
df = pd.concat(df)

After the failed install you have to repair the 2015 vc redistributables and restart the visual studio installer.

The redistributable installer is messed up, it mixes up 64bit and 32bit dll's. You can check if you have this problem by looking at the vcruntime140.dll file size. Search your windows folder for vcruntime140 you should see 4 files (64 and 32 bit in both release & debug versions). If any files have the same size, you need to run a repair on the redistributable.

On my system the 32-bit dll is 83,3KB, the 64 bit is 86,6KB (release versions).

'origin/master' which can not be resolved as commit

Strange: you need to check your remotes:

git remote -v

And make sure origin is fetched:

git fetch origin

Then:

git branch -avv

(to see if you do have fetched an origin/master branch)

Finally, use git switch instead of the confusing git checkout, with Git 2.23+ (August 2019).

git switch -c test --track origin/master

It depends on whether the setting you have chosen is at "User" scope or "Application" scope.

User scope

User scope settings are stored in

C:\Documents and Settings\ username \Local Settings\Application Data\ ApplicationName

You can read/write them at runtime.

For Vista and Windows 7, folder is

C:\Users\ username \AppData\Local\ ApplicationName

or

C:\Users\ username \AppData\Roaming\ ApplicationName

Application scope

Application scope settings are saved in AppName.exe.config and they are readonly at runtime.

QuerySelectorAll will get all the matching elements with defined selector. Here on the example I've used element's name(li tag) to get all of the li present inside the div with navbar element.

    let navbar = document_x000D_
      .getElementById("navbar")_x000D_
      .querySelectorAll('li');_x000D_
_x000D_
    navbar.forEach((item, index) => {_x000D_
      console.log({ index, item })_x000D_
    });

   _x000D_
<div id="navbar">_x000D_
 <ul>_x000D_
  <li id="navbar-One">One</li>_x000D_
  <li id="navbar-Two">Two</li>_x000D_
  <li id="navbar-Three">Three</li>_x000D_
  <li id="navbar-Four">Four</li>_x000D_
  <li id="navbar-Five">Five</li>_x000D_
 </ul>_x000D_
</div>

Here are a couple of things missing in the previous answers:

1. Set header in your PHP:

   header('Content-type: application/json');
   echo json_encode($array);
   

2. json_encode() can return a JavaScript array instead of JavaScript object, see:
   Returning JSON from a PHP Script
   This could be important to know in some cases as arrays and objects are not the same.

If you need a directive more advanced, I recomend the solution that I implemnted, correctly tested on Internet Explorer 11, Chrome and FireFox.

I hope it, will be helpfull.

Get yesterday date in javascript

You have to run code and check it output

    var today = new Date();_x000D_
    var yesterday = new Date(today);_x000D_
    _x000D_
    yesterday.setDate(today.getDate() - 1);_x000D_
    console.log("Original Date : ",yesterday);_x000D_
_x000D_
    const monthNames = [_x000D_
  "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"_x000D_
];_x000D_
    var month = today.getMonth() + 1_x000D_
    yesterday = yesterday.getDate() + ' ' + monthNames[month] + ' ' + yesterday.getFullYear()_x000D_

    console.log("Modify Date : ",yesterday);

Here is what I did recently in PHP on one of my bigger systems:

1. User inputs newsletter text and selects the recipients (which generates a query to retrieve the email addresses for later).

2. Add the newsletter text and recipients query to a row in mysql table called *email_queue*

   • (The table email_queue has the columns "to" "subject" "body" "priority")

3. I created another script, which runs every minute as a cron job. It uses the SwiftMailer class. This script simply:

   • during business hours, sends all email with priority == 0

   • after hours, send other emails by priority

Depending on the hosts settings, I can now have it throttle using standard swiftmailers plugins like antiflood and throttle...

$mailer->registerPlugin(new Swift_Plugins_AntiFloodPlugin(50, 30));

and

$mailer->registerPlugin(new Swift_Plugins_ThrottlerPlugin( 100, Swift_Plugins_ThrottlerPlugin::MESSAGES_PER_MINUTE ));

etc, etc..

I have expanded it way beyond this pseudocode, with attachments, and many other configurable settings, but it works very well as long as your server is setup correctly to send email. (Probably wont work on shared hosting, but in theory it should...) Swiftmailer even has a setting

$message->setReturnPath

Which I now use to track bounces...

Happy Trails! (Happy Emails?)

The problem appears to be internal bubbling within the <video> element ... so when you click on the "Play" button the code triggers and then the play button itself get triggered :(

I couldn't find a simple (reliable) way to stop the click bubbling through (logic tells me there should be a way, but... it escapes me right now)

Anyway, the solution I found to this was to put a transparent <div> over the video sized to fit down to where the controls appear... so if you click on the div then your script controls play/pause but if the user clicks on the controls themselves then the <video> element handles that for you.

The sample below was sized for my video so you may need to juggle sizes of the relative <div>s but it should get you started

<div id="vOverlay" style="position:relative; width:600px; height:300px; z-index:2;"></div>
<video style="position:relative; top:-300px; z-index:1;width:600px;height:340px;" width="600" height="409" id=videoPlayer controls="controls">
<source src="video.mp4" type="video/mp4">
</video>

<script>
    var v = document.getElementById('videoPlayer');
    var vv = document.getElementById('vOverlay');
    <!-- Auto play, Half volume -->
    v.play()
    v.volume = 0.5;
    v.firstChild.nodeValue = "Play";

    <!-- Play, Pause -->
    vv.addEventListener('click',function(e){
        if (!v.paused) {
            console.log("pause playback");
            v.pause();
            v.firstChild.nodeValue = 'Pause';
        } else {
            console.log("start playback")
            v.play();
            v.firstChild.nodeValue = 'Play';
        }
      });
</script>

One significant difference is that you can include a function in your SQL queries, but stored procedures can only be invoked with the CALL statement:

UDF Example:

CREATE FUNCTION hello (s CHAR(20))
   RETURNS CHAR(50) DETERMINISTIC
   RETURN CONCAT('Hello, ',s,'!');
Query OK, 0 rows affected (0.00 sec)

CREATE TABLE names (id int, name varchar(20));
INSERT INTO names VALUES (1, 'Bob');
INSERT INTO names VALUES (2, 'John');
INSERT INTO names VALUES (3, 'Paul');

SELECT hello(name) FROM names;
+--------------+
| hello(name)  |
+--------------+
| Hello, Bob!  |
| Hello, John! |
| Hello, Paul! |
+--------------+
3 rows in set (0.00 sec)

Sproc Example:

delimiter //

CREATE PROCEDURE simpleproc (IN s CHAR(100))
BEGIN

this will output

Browsers other than IE treat the conditional statements as comments because they're enclosed inside comment tags.

<!--[if IE]>
Non-IE browsers ignore this
<![endif]-->

However, when you're targeting a browser that is NOT IE you have to use 2 comments, one before and one after the code. IE will ignore the code between them, whereas other browsers will treat it as normal code. The syntax for targeting non-IE browsers is therefore:

<!--[if !IE]-->
IE ignores this
<!--[endif]-->

Note: These conditional comments are no longer supported from IE 10 onwards.

awk works well if you your server has it

var="text,text,text,text" 
num=$(echo "${var}" | awk -F, '{print NF-1}')
echo "${num}"

You need to use parentheses: myList.insert([1, 2, 3]). When you leave out the parentheses, python thinks you are trying to access myList.insert at position 1, 2, 3, because that's what brackets are used for when they are right next to a variable.

You have to do this to echo it:

echo $row['note'];

(The data is coming as an array)

Use a couple of functions and a boolean. Here's a pattern, not full code:

 var state = false,
     oddONes = function () {...},
     evenOnes = function() {...};

 $("#time").click(function(){
     if(!state){
        evenOnes();
     } else {
        oddOnes();
     }
     state = !state;
  });

Or

  var cases[] = {
      function evenOnes(){...},  // these could even be anonymous functions
      function oddOnes(){...}    // function(){...}
  };

  var idx = 0; // should always be 0 or 1

  $("#time").click(function(idx){cases[idx = ((idx+1)%2)]()}); // corrected

(Note the second is off the top of my head and I mix languages a lot, so the exact syntax isn't guaranteed. Should be close to real Javascript through.)

You use uninstall the app and change the sharedPreferences name then run this application. I think it will resolve the issue.

A sample code to retrieve values from sharedPreferences you can use the following set of code,

SharedPreferences shared = getSharedPreferences(PREF_NAME, MODE_PRIVATE);
String channel = (shared.getString(keyValue, ""));

I would use Google Collections. There is a nice Join facility.
http://google-collections.googlecode.com/svn/trunk/javadoc/index.html?com/google/common/base/Join.html

But if I wanted to write it on my own,

package util;

import java.util.ArrayList;
import java.util.Iterable;
import java.util.Collections;
import java.util.Iterator;

public class Utils {
    // accept a collection of objects, since all objects have toString()
    public static String join(String delimiter, Iterable<? extends Object> objs) {
        if (objs.isEmpty()) {
            return "";
        }
        Iterator<? extends Object> iter = objs.iterator();
        StringBuilder buffer = new StringBuilder();
        buffer.append(iter.next());
        while (iter.hasNext()) {
            buffer.append(delimiter).append(iter.next());
        }
        return buffer.toString();
    }

    // for convenience
    public static String join(String delimiter, Object... objs) {
        ArrayList<Object> list = new ArrayList<Object>();
        Collections.addAll(list, objs);
        return join(delimiter, list);
    }
}

I think it works better with an object collection, since now you don't have to convert your objects to strings before you join them.

Run -> Edit configurations -> Select your build configuration -> JRE - change Default to one of actual JDK paths

During an object's de-serialization, the class responsible for de-serializing an object creates an instance of the serialized class and then proceeds to populate the serialized fields and properties only after acquiring an instance to populate.

You can make your constructor private or internal if you want, just so long as it's parameterless.

With the user.language, user.country and user.variant properties.

Example:

java -Duser.language=th -Duser.country=TH -Duser.variant=TH SomeClass

If you're using Swift, it's as simple as:

subviews.map { $0.removeFromSuperview }

It's similar in philosophy to the makeObjectsPerformSelector approach, however with a little more type safety.

add KexAlgorithms diffie-hellman-group1-sha1,diffie-hellman-group-exchange-sha??1 to your sshd_config on the server.

This worked, but make sure you restart sshd: sudo service sshd restart

You may use pyenv.

There are a lot of different versions anaconda, jython, pypy and so on...

FYI (merged version of Tvanfosson)

it will return actual date => date when you are calling function

export const today = {
  iso: {
    start: () => new Date(new Date().setHours(0, 0, 0, 0)).toISOString(),
    now: () => new Date().toISOString(),
    end: () => new Date(new Date().setHours(23, 59, 59, 999)).toISOString()
  },
  local: {
  start: () => new Date(new Date(new Date().setHours(0, 0, 0, 0)).toString().split('GMT')[0] + ' UTC').toISOString(),
  now: () => new Date(new Date().toString().split('GMT')[0] + ' UTC').toISOString(),
  end: () => new Date(new Date(new Date().setHours(23, 59, 59, 999)).toString().split('GMT')[0] + ' UTC').toISOString()
  }
}

// how to use

today.local.now(); //"2018-09-07T01:48:48.000Z" BAKU +04:00
today.iso.now(); // "2018-09-06T21:49:00.304Z" * 

* it is applicable for Instant time type on Java8 which convert your local time automatically depending on your region.(if you are planning write global app)

The accepted answer resulted in errors for me when attempting REASSIGN OWNED BY or DROP OWNED BY. The following worked for me:

REVOKE ALL PRIVILEGES ON ALL TABLES IN SCHEMA public FROM username;
REVOKE ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public FROM username;
REVOKE ALL PRIVILEGES ON ALL FUNCTIONS IN SCHEMA public FROM username;
DROP USER username;

The user may have privileges in other schemas, in which case you will have to run the appropriate REVOKE line with "public" replaced by the correct schema. To show all of the schemas and privilege types for a user, I edited the \dp command to make this query:

SELECT 
  n.nspname as "Schema",
  CASE c.relkind 
    WHEN 'r' THEN 'table' 
    WHEN 'v' THEN 'view' 
    WHEN 'm' THEN 'materialized view' 
    WHEN 'S' THEN 'sequence' 
    WHEN 'f' THEN 'foreign table' 
  END as "Type"
FROM pg_catalog.pg_class c
LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
WHERE pg_catalog.array_to_string(c.relacl, E'\n') LIKE '%username%';

I'm not sure which privilege types correspond to revoking on TABLES, SEQUENCES, or FUNCTIONS, but I think all of them fall under one of the three.

Usually, this means that your program is locked and might not be killed through task manager or process explorer. I met a similar case that my program had an exception during running and triggered the windows error reporting which locked the program. For the case that windows error reporting locks the program, you can go to control panel->System and Security->Action Center->Problem Reporting Settings to set "Never check for solutions". Hope it helps.

You use it to debug JavaScript code with either Firebug for Firefox, or JavaScript console in WebKit browsers.

var variable;

console.log(variable);

It will display the contents of the variable, even if it is a array or object.

It is similar to print_r($var); for PHP.

You can of course format the result of current_timestamp(). Please have a look at the various formatting functions in the official documentation.

I think it is considered "more pythonic" to just use in when determining if a key already exists, as in

if start not in graph:
    return None

I don't like the auto-commit that git revert does, so this might be helpful for some.

If you just want the modified files not the auto-commit, you can use --no-commit

% git revert --no-commit <commit hash>

which is the same as the -n

% git revert -n <commit hash>

Maybe this command can be helpful :

git archive --remote=MyRemoteGitRepo --format=tar BranchName_or_commit  path/to/your/dir/or/file > files.tar

"Et voilà"

If you do not need speed, sockets are the easiest way to go!

If what you are looking at is speed, the fastest solution is shared Memory, not named pipes.

Just Restart-Service hns can change the port occupier by Hyper-V. It might release the port you need.

Yes, you should update your code to use Firebase Messaging interface. There's a GitHub Project for that here.

I normally use Emacs (it has everything you need included).

Of course, there are other options available:

• Kile is KDE's LaTeX editor; it's excellent if you're just learning or if you prefer the integrated environment approach;
• Lyx is a WYSIWYG editor that uses LaTeX as a backend; i.e. you tell it what the text should look like and it generates the corresponding LaTeX

A pem file contains the certificate and the private key. It depends on the format your certificate/key are in, but probably it's as simple as this:

cat server.crt server.key > server.pem

There are other libraries that are JSON compatible, which support comments.

One notable example is the "Hashcorp Language" (HCL)". It is written by the same people who made Vagrant, packer, consul, and vault.

For the people stumbling across this question and getting a similar error message in regards to an nvarchar instead of money:

The given value of type String from the data source cannot be converted to type nvarchar of the specified target column.

This could be caused by a too-short column.

For example, if your column is defined as nvarchar(20) and you have a 40 character string, you may get this error.

The problem with all these solutions (using the > redirector character) is that you write your dump from stdout which may break the encoding of some characters of your database.

If you have a character encoding issue. Such as :

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ...

then, you MUST use -r option to write the file.

MySQL

mysqldump -u user -pyour-password-without-space-between-letter-p-and-your-password --default-character-set=utf8 --host $HOST database-name -r dump.sql

Using Docker

docker exec --rm -v $pwd:dump -it mysql:5:7 mysqldump -u user -pyour-password-without-space-between-letter-p-and-your-password --default-character-set=utf8 --host $HOST database-name -r dump/dump.sql

Note: this mounts the current path as dump inside the instance.

We found the answer here

Conversely, don't use < to import your dump into your database, again, your non-utf8 characters may not be passed; but prefer source option.

mysql -u user -pYourPasswordYouNowKnowHow --default-character-set=utf8 your-database
mysql> SET names 'utf8'
mysql> SOURCE dump.sql

I'd like to expand on Obertklep's answer. In his example it is an NPM module called body-parser which is doing most of the work. Where he puts req.body.name, I believe he/she is using body-parser to get the contents of the name attribute(s) received when the form is submitted.

If you do not want to use Express, use querystring which is a built-in Node module. See the answers in the link below for an example of how to use querystring.

It might help to look at this answer, which is very similar to your quest.

You could use the Export->Java->Runnable Jar to create a jar that includes its dependencies

Alternatively, you could use the fatjar eclipse plugin as well to bundle jars together

I believe it makes sense revisit this question as also pointed out in the comments, the introduction of OpenID Connect may have brought more confusion.

OpenID Connect is an authentication protocol like OpenID 1.0/2.0 but it is actually built on top of OAuth 2.0, so you'll get authorization features along with authentication features. The difference between the two is pretty well explained in detail in this (relatively recent, but important) article: http://oauth.net/articles/authentication/

Simply read

Pro Git Book: 4.2 Git on the Server - Getting Git on a Server

which boild down to

$ git clone --bare my_project my_project.git
Cloning into bare repository 'my_project.git'...
done.

Then put my_project.git to the server

Which mainly is, what answer #42 tried to point out. Shurely one could reinvent the wheel ;-)

Note: Change the width percentage as per your need in 1st solution.

You can also use a regular expression as a field separator. The following will print "bar" by using a regular expression to set the number "10" as a separator.

echo "foo 10 bar" | awk -F'[0-9][0-9]' '{print $2}'

const event = new Date();

console.log(event.toUTCString());

1. bind() of INADDR_ANY does NOT "generate a random IP". It binds the socket to all available interfaces.

2. For a server, you typically want to bind to all interfaces - not just "localhost".

3. If you wish to bind your socket to localhost only, the syntax would be my_sockaddress.sin_addr.s_addr = inet_addr("127.0.0.1");, then call bind(my_socket, (SOCKADDR *) &my_sockaddr, ...).

4. As it happens, INADDR_ANY is a constant that happens to equal "zero":

   http://www.castaglia.org/proftpd/doc/devel-guide/src/include/inet.h.html

   # define INADDR_ANY ((unsigned long int) 0x00000000)
   ...
   # define INADDR_NONE    0xffffffff
   ...
   # define INPORT_ANY 0
   ...
   

5. If you're not already familiar with it, I urge you to check out Beej's Guide to Sockets Programming:

   http://beej.us/guide/bgnet/

Since people are still reading this, an additional note:

man (7) ip:

When a process wants to receive new incoming packets or connections, it should bind a socket to a local interface address using bind(2).

In this case, only one IP socket may be bound to any given local (address, port) pair. When INADDR_ANY is specified in the bind call, the socket will be bound to all local interfaces.

When listen(2) is called on an unbound socket, the socket is automatically bound to a random free port with the local address set to INADDR_ANY.

When connect(2) is called on an unbound socket, the socket is automatically bound to a random free port or to a usable shared port with the local address set to INADDR_ANY...

There are several special addresses: INADDR_LOOPBACK (127.0.0.1) always refers to the local host via the loopback device; INADDR_ANY (0.0.0.0) means any address for binding...

Also:

bind() — Bind a name to a socket:

If the (sin_addr.s_addr) field is set to the constant INADDR_ANY, as defined in netinet/in.h, the caller is requesting that the socket be bound to all network interfaces on the host. Subsequently, UDP packets and TCP connections from all interfaces (which match the bound name) are routed to the application. This becomes important when a server offers a service to multiple networks. By leaving the address unspecified, the server can accept all UDP packets and TCP connection requests made for its port, regardless of the network interface on which the requests arrived.

Beside this, there should be no differences. More precisely,

both formats support exactly the same feature set

I am surprised no-one has suggested using itertools.accumulate with operator.mul. This avoids using reduce, which is different for Python 2 and 3 (due to the functools import required for Python 3), and moreover is considered un-pythonic by Guido van Rossum himself:

from itertools import accumulate
from operator import mul

def prod(lst):
    for value in accumulate(lst, mul):
        pass
    return value

Example:

prod([1,5,4,3,5,6])
# 1800

Your terminal happens to be configured to UTF-8.

The fact that printing a works is a coincidence; you are writing raw UTF-8 bytes to the terminal. a is a value of length two, containing two bytes, hex values C3 and A1, while ua is a unicode value of length one, containing a codepoint U+00E1.

This difference in length is one major reason to use Unicode values; you cannot easily measure the number of text characters in a byte string; the len() of a byte string tells you how many bytes were used, not how many characters were encoded.

You can see the difference when you encode the unicode value to different output encodings:

>>> a = 'á'
>>> ua = u'á'
>>> ua.encode('utf8')
'\xc3\xa1'
>>> ua.encode('latin1')
'\xe1'
>>> a
'\xc3\xa1'

Note that the first 256 codepoints of the Unicode standard match the Latin 1 standard, so the U+00E1 codepoint is encoded to Latin 1 as a byte with hex value E1.

Furthermore, Python uses escape codes in representations of unicode and byte strings alike, and low code points that are not printable ASCII are represented using \x.. escape values as well. This is why a Unicode string with a code point between 128 and 255 looks just like the Latin 1 encoding. If you have a unicode string with codepoints beyond U+00FF a different escape sequence, \u.... is used instead, with a four-digit hex value.

It looks like you don't yet fully understand what the difference is between Unicode and an encoding. Please do read the following articles before you continue:

Edit: Now returning dictionaries when querying with wild cards (None), and single values otherwise.

Using the compiler to do implies memory leaks as the generated assemblies are loaded and never released. It's also less performant than using a real expression interpreter. For this purpose you can use Ncalc which is an open-source framework with this solely intent. You can also define your own variables and custom functions if the ones already included aren't enough.

Example:

Expression e = new Expression("2 + 3 * 5");
Debug.Assert(17 == e.Evaluate());

This is what i've done works like a charm

            private static int _x=0, _y=0;
        private static Point _point;
        public static Point LocationInForm(Control c)
        {
            if (c.Parent == null) 
            {
                _x += c.Location.X;
                _y += c.Location.Y;
                _point = new Point(_x, _y);
                _x = 0; _y = 0;
                return _point;
            }
            else if ((c.Parent is System.Windows.Forms.Form))
            {
                _point = new Point(_x, _y);
                _x = 0; _y = 0;
                return _point;
            }
            else 
            {
                _x += c.Location.X;
                _y += c.Location.Y;
                LocationInForm(c.Parent);
            }
            return new Point(1,1);
        }

There is one more way to achieve it:-

Private Sub UserForm_Initialize()
Dim list As Object
Set list = UserForm1.Controls.Add("Forms.ListBox.1", "hello", True)
With list
    .Top = 30
    .Left = 30
    .Width = 200
    .Height = 340
    .ColumnHeads = True
    .ColumnCount = 2
    .ColumnWidths = "100;100"
    .MultiSelect = fmMultiSelectExtended
    .RowSource = "Sheet1!C4:D25"
End With End Sub

Here, I am using the range C4:D25 as source of data for the columns. It will result in both the columns populated with values.

The properties are self explanatory. You can explore other options by drawing ListBox in UserForm and using "Properties Window (F4)" to play with the option values.

Wait and await - while similar conceptually - are actually completely different.

Wait will synchronously block until the task completes. So the current thread is literally blocked waiting for the task to complete. As a general rule, you should use "async all the way down"; that is, don't block on async code. On my blog, I go into the details of how blocking in asynchronous code causes deadlock.

await will asynchronously wait until the task completes. This means the current method is "paused" (its state is captured) and the method returns an incomplete task to its caller. Later, when the await expression completes, the remainder of the method is scheduled as a continuation.

You also mentioned a "cooperative block", by which I assume you mean a task that you're Waiting on may execute on the waiting thread. There are situations where this can happen, but it's an optimization. There are many situations where it can't happen, like if the task is for another scheduler, or if it's already started or if it's a non-code task (such as in your code example: Wait cannot execute the Delay task inline because there's no code for it).

You may find my async / await intro helpful.

To create simple OR condition for collection, use format below:

    $orders = Mage::getModel('sales/order')->getResourceCollection();
    $orders->addFieldToFilter(
      'status',
      array(
        'processing',
        'pending',
      )
    );

This will produce SQL like this:

WHERE (((`status` = 'processing') OR (`status` = 'pending')))

Assuming you wanted to do this synchronously, using the WebClient.OpenRead(...) method and setting the timeout on the Stream that it returns will give you the desired result:

using (var webClient = new WebClient())
using (var stream = webClient.OpenRead(streamingUri))
{
     if (stream != null)
     {
          stream.ReadTimeout = Timeout.Infinite;
          using (var reader = new StreamReader(stream, Encoding.UTF8, false))
          {
               string line;
               while ((line = reader.ReadLine()) != null)
               {
                    if (line != String.Empty)
                    {
                        Console.WriteLine("Count {0}", count++);
                    }
                    Console.WriteLine(line);
               }
          }
     }
}

Deriving from WebClient and overriding GetWebRequest(...) to set the timeout @Beniamin suggested, didn't work for me as, but this did.

I find that I run into Net::HTTP and Net::FTP problems like this periodically, and when I do, surrounding the call with a timeout() makes all of those issues vanish. So where this will occasionally hang for 3 minutes or so and then raise an EOFError:

res = Net::HTTP.post_form(uri, args)

This always fixes it for me:

res = timeout(120) { Net::HTTP.post_form(uri, args) }

NuPKG files are just zip files, so anything that can process a zip file should be able to process a nupkg file, i.e, 7zip.

I needed to have timezone information in my date string. I was originally using moment.tz(dateStr, 'America/New_York').toString(); but then I started getting errors about feeding that string back into moment.

I tried the moment.tz(dateStr, 'America/New_York').toDate(); but then I lost timezone information which I needed.

The only solution that returned a usable date string with timezone that could be fed back into moment was moment.tz(dateStr, 'America/New_York').format();

You can use the Where to filter and Select to get the desired value.

MyList.Where(i=>i.name == yourName).Select(j=>j.value);

just renaming the DB (to be delete) did the trick for me. it got off the hold of whatever process was accessing the database, and so I was able to drop the database.

I just had this with 15.8.3 after uninstalling some .NET Core 1.x preview SDKs, my application would not compile and showed the error.

It was fixed by installing the latest x86 version of the SDK even though I'm on Windows 10 x64.

I presume this is because VS 2017 is still a x86 program and though the programs run as x64 the compiler was looking for an appropriate x86 SDK

InputMethodManager inputManager = (InputMethodManager)
                                  getSystemService(Context.INPUT_METHOD_SERVICE); 

inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(),
                                     InputMethodManager.HIDE_NOT_ALWAYS);

I put this right after the onClick(View v) event.

You need to import android.view.inputmethod.InputMethodManager;

The keyboard hides when you click the button.

I use this and it works right

@Id
@GeneratedValue(generator = "SEC_ODON", strategy = GenerationType.SEQUENCE)
@SequenceGenerator(name = "SEC_ODON", sequenceName = "SO.SEC_ODON",allocationSize=1)
@Column(name="ID_ODON", unique=true, nullable=false, precision=10, scale=0)
public Long getIdOdon() {
    return this.idOdon;
}

If your div has a fixed-width it shouldn't expand, because you've fixed its width. However, modern browsers support a min-width CSS property.

You can emulate the min-width property in old IE browsers by using CSS expressions or by using auto width and having a spacer object in the container. This solution isn't elegant but may do the trick:

<div id="container" style="float: left">
  <div id="spacer" style="height: 1px; width: 300px"></div>
  <button>Button 1 text</button>
  <button>Button 2 text</button>
</div>

The following is the correct overload (in your example you are missing a closing } to the routeValues anonymous object so your code will throw an exception):

<a href="<%: Url.Action("GetByList", "Listing", new { name = "John", contact = "calgary, vancouver" }) %>">
    <span>People</span>
</a>

Assuming you are using the default routes this should generate the following markup:

<a href="/Listing/GetByList?name=John&amp;contact=calgary%2C%20vancouver">
    <span>People</span>
</a>

which will successfully invoke the GetByList controller action passing the two parameters:

public ActionResult GetByList(string name, string contact) 
{
    ...
}

Take a look QRCoder - pure C# open source QR code generator. Can be used in three lines of code

QRCodeGenerator qrGenerator = new QRCodeGenerator();
QRCodeGenerator.QRCode qrCode = qrGenerator.CreateQrCode(textBoxQRCode.Text, QRCodeGenerator.ECCLevel.Q);
pictureBoxQRCode.BackgroundImage = qrCode.GetGraphic(20);

You can use the unicode of a non breaking space :

p:before { content: "\00a0 "; }

Here is the code of TextScanner

public class TextScanner {

        private static void readFile(String fileName) {
            try {
              File file = new File("/opt/pol/data22/ds_data118/0001/0025090290/2014/12/12/0029057983.ds");
              Scanner scanner = new Scanner(file);
              while (scanner.hasNext()) {
                System.out.println(scanner.next());
              }
              scanner.close();
            } catch (FileNotFoundException e) {
              e.printStackTrace();
            }
          }

          public static void main(String[] args) {
            if (args.length != 1) {
              System.err.println("usage: java TextScanner1"
                + "file location");
              System.exit(0);
            }
            readFile(args[0]);
      }
}

It will print text with delimeters

$data =array();
$data['user_code']  = 'JOY' ;
$data['user_name']  = 'JOY' ;
$data['user_email'] = '[email protected]';

If you want to run it @build time :

CMD /bin/bash /file.sh arg1

if you want to run it @run time :

ENTRYPOINT ["/bin/bash"]
CMD ["/file.sh", "arg1"]

Then in the host shell

docker build -t test .
docker run -i -t test

Try to use (focus) and (focusout) instead of onfocus and onfocusout

like this : -

<input name="date" type="text" (focus)="focusFunction()" (focusout)="focusOutFunction()">

also you can use like this :-

some people prefer the on- prefix alternative, known as the canonical form:

<input name="date" type="text" on-focus="focusFunction()" on-focusout="focusOutFunction()">

Know more about event binding see here.

you have to use HostListner for your use case

Angular will invoke the decorated method when the host element emits the specified event.@HostListener is a decorator for the callback/event handler method

See my Update working Plunker.

Working Example Working Stackblitz

Update

Some other events can be used in angular -

(focus)="myMethod()"
(blur)="myMethod()" 
(submit)="myMethod()"  
(scroll)="myMethod()"
