It's not clear whether you're asking this because you are new to programming, but if that's the case then you should probably read this article on loops and indeed read some basic materials on programming.

If you already know about control structures and you want the R-specific implementation details then there are dozens of tutorials around, such as this one. The other answer uses replicate and colMeans, which is idiomatic when writing in R and probably blazing fast as well, which is important if you want 10,000 iterations.

However, one more general and (for beginners) straightforward way to approach problems of this sort would be to use a for loop.

> for (ii in 1:5) { + print(ii) + } [1] 1 [1] 2 [1] 3 [1] 4 [1] 5 > 

So in your case, if you just wanted to print the mean of your Tandem object 5 times:

for (ii in 1:5) {     Tandem <- sample(OUT, size = 815, replace = TRUE, prob = NULL)     TandemMean <- mean(Tandem)     print(TandemMean) } 

As mentioned above, replicate is a more natural way to deal with this specific problem using R. Either way, if you want to store the results - which is surely the case - you'll need to start thinking about data structures like vectors and lists. Once you store something you'll need to be able to access it to use it in future, so a little knowledge is vital.

set.seed(1234) OUT <- runif(100000, 1, 2) tandem <- list() for (ii in 1:10000) {     tandem[[ii]] <- mean(sample(OUT, size = 815, replace = TRUE, prob = NULL)) }  tandem[1] tandem[100] tandem[20:25] 

...creates this output:

> set.seed(1234) > OUT <- runif(100000, 1, 2) > tandem <- list() > for (ii in 1:10000) { +     tandem[[ii]] <- mean(sample(OUT, size = 815, replace = TRUE, prob = NULL)) + } >  > tandem[1] [[1]] [1] 1.511923  > tandem[100] [[1]] [1] 1.496777  > tandem[20:25] [[1]] [1] 1.500669  [[2]] [1] 1.487552  [[3]] [1] 1.503409  [[4]] [1] 1.501362  [[5]] [1] 1.499728  [[6]] [1] 1.492798  >  

I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.

Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled

Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is

1. Remove the XAML for the ad
2. Remove the xmlns declaration (usually at the top of the page, but sometimes will be declared in the ad itself)
3. Remove the bad DLL (the one ending in .SDK )
4. Do a Clean and then Build (clean out anything remaining from the DLL)
5. Add the xmlns reference (actual reference is below)
6. Add the ad to the page (example below)

Here is the xmlns reference:

xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI" 

Then the ad itself:

<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480"                    AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/> 

You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.

CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace);  CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession);  CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context);       

In the nav go View => Layout => Columns:2 (alt+shift+2) and open your file again in the other pane (i.e. click the other pane and use ctrl+p filename.py)

It appears you can also reopen the file using the command File -> New View into File which will open the current file in a new tab

You will need to do a couple of things to get this going, since your parameter is getting multiple values you need to create a Table Type and make your store procedure accept a parameter of that type.

Split Function Works Great when you are getting One String containing multiple values but when you are passing Multiple values you need to do something like this....

TABLE TYPE

CREATE TYPE dbo.TYPENAME AS TABLE   (     arg int    )  GO 

Stored Procedure to Accept That Type Param

 CREATE PROCEDURE mainValues   @TableParam TYPENAME READONLY  AS     BEGIN     SET NOCOUNT ON;   --Temp table to store split values   declare @tmp_values table (   value nvarchar(255) not null);        --function splitting values     INSERT INTO @tmp_values (value)    SELECT arg FROM @TableParam      SELECT * FROM @tmp_values  --<-- For testing purpose END 

EXECUTE PROC

Declare a variable of that type and populate it with your values.

 DECLARE @Table TYPENAME     --<-- Variable of this TYPE   INSERT INTO @Table                --<-- Populating the variable   VALUES (331),(222),(876),(932)  EXECUTE mainValues @Table   --<-- Stored Procedure Executed  

Result

╔═══════╗ ║ value ║ ╠═══════╣ ║   331 ║ ║   222 ║ ║   876 ║ ║   932 ║ ╚═══════╝ 

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

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

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

And in §7.19.3/2

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

About use of fseek, in §7.19.9.2/4:

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

About use of ftell, in §17.19.9.4:

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

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

You can use Jquery's on method and listen for the scroll event.

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

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

being overwhelmed by being VERY NEW to python i missed some very simple and useful commands given here: Print in terminal with colors using Python? -

eventually decided to use CLINT as an answer that was given there by great and smart people

The linked list holds operations on the shared data structure.

For example, if I have a stack, it will be manipulated with pushes and pops. The linked list would be a set of pushes and pops on the pseudo-shared stack. Each thread sharing that stack will actually have a local copy, and to get to the current shared state, it'll walk the linked list of operations, and apply each operation in order to its local copy of the stack. When it reaches the end of the linked list, its local copy holds the current state (though, of course, it's subject to becoming stale at any time).

In the traditional model, you'd have some sort of locks around each push and pop. Each thread would wait to obtain a lock, then do a push or pop, then release the lock.

In this model, each thread has a local snapshot of the stack, which it keeps synchronized with other threads' view of the stack by applying the operations in the linked list. When it wants to manipulate the stack, it doesn't try to manipulate it directly at all. Instead, it simply adds its push or pop operation to the linked list, so all the other threads can/will see that operation and they can all stay in sync. Then, of course, it applies the operations in the linked list, and when (for example) there's a pop it checks which thread asked for the pop. It uses the popped item if and only if it's the thread that requested this particular pop.

Seeing that it appears you are running using the SQL syntax, try with the correct wild card.

SELECT * FROM someTable WHERE (someTable.Field NOT LIKE '%RISK%') AND (someTable.Field NOT LIKE '%Blah%') AND someTable.SomeOtherField <> 4; 

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.

As noted in the release email, linked to from the release tweet and noted in large orange warning that appears on the front page of the documentation, and less orange, but still present, in the readme on the repository and the release on pypi:

xlrd has explicitly removed support for anything other than xls files.

In your case, the solution is to:

• make sure you are on a recent version of Pandas, at least 1.0.1, and preferably the latest release. 1.2 will make his even clearer.
• install openpyxl: https://openpyxl.readthedocs.io/en/stable/
• change your Pandas code to be:

  df1 = pd.read_excel(
       os.path.join(APP_PATH, "Data", "aug_latest.xlsm"),
       engine='openpyxl',
  )
  

First we'll install @babel/cli, @babel/core and @babel/preset-env.

$ npm install --save-dev @babel/cli @babel/core @babel/preset-env

Then we'll create a .babelrc file for configuring babel.

$ touch .babelrc

This will host any options we might want to configure babel with.

{
  "presets": ["@babel/preset-env"]
}

With recent changes to babel, you will need to transpile your ES6 before node can run it.

So, we'll add our first script, build, in package.json.

"scripts": {
  "build": "babel index.js -d dist"
}

Then we'll add our start script in package.json.

"scripts": {
  "build": "babel index.js -d dist", // replace index.js with your filename
  "start": "npm run build && node dist/index.js"
}

Now let's start our server.

$ npm start

When it comes to Google Analytics I found raik's answer at Secure Google tracking cookies very useful. It set secure and samesite to a value.

ga('create', 'UA-XXXXX-Y', {
    cookieFlags: 'max-age=7200;secure;samesite=none'
});

For my situation this error was caused by having circular references in json sent from the server when using an ORM for parent/child relationships. So the quick and easy solution was

JsonConvert.SerializeObject(myObject, new JsonSerializerSettings { ReferenceLoopHandling = ReferenceLoopHandling.Ignore })

The better solution is to create DTOs that do not contain the references on both sides (parent/child).

I am using both JavaScript Cookie and Java CookieUtil in my project, below settings solved my problem:

JavaScript Cookie

var d = new Date();
d.setTime(d.getTime() + (30*24*60*60*1000)); //keep cookie 30 days
var expires = "expires=" + d.toGMTString();         
document.cookie = "visitName" + "=Hailin;" + expires + ";path=/;SameSite=None;Secure"; //can set SameSite=Lax also

JAVA Cookie (set proxy_cookie_path in Nginx)

location / {
   proxy_pass http://96.xx.xx.34;
   proxy_intercept_errors on;
   #can set SameSite=None also
   proxy_cookie_path / "/;SameSite=Lax;secure";
   proxy_connect_timeout 600;
   proxy_read_timeout 600;
}

Check result in Firefox

For me, I was trying to install an old version of bcrypt which was not found in npm, I just edited package.json and manually put the latest version and then ran npm install and it worked

change the data type to another one which uses less memory works. For me, I change the data type to numpy.uint8:

data['label'] = data['label'].astype(np.uint8)

This happens because you try to access plotOptions property using string name. TypeScript understands that name may have any value, not only property name from plotOptions. So TypeScript requires to add index signature to plotOptions, so it knows that you can use any property name in plotOptions. But I suggest to change type of name, so it can only be one of plotOptions properties.

interface trainInfo {
    name: keyof typeof plotOptions;
    x: Array<number>;
    y: Array<number>;
    type: string;
    mode: string;
}

Now you'll be able to use only property names that exist in plotOptions.

You also have to slightly change your code.

First assign array to some temp variable, so TS knows array type:

const plotDataTemp: Array<trainInfo> = [
    {
      name: "train_1",
      x: data.filtrationData.map((i: any) => i["1-CumVol"]),
      y: data.filtrationData.map((i: any) => i["1-PressureA"]),
      type: "scatter",
      mode: "lines"
    },
    // ...
}

Then filter:

const plotData = plotDataTemp.filter(({ name }) => plotOptions[name]);

If you're getting data from API and have no way to type check props at compile time the only way is to add index signature to your plotOptions:

type tplotOptions = {
    [key: string]: boolean
}

const plotOptions: tplotOptions = {
    train_1: true,
    train_2: true,
    train_3: true,
    train_4: true
}

You can convert class component to hooks,but Material v4 has a withStyles HOC. https://material-ui.com/styles/basics/#higher-order-component-api Using this HOC you can keep your code unchanged.

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;

start your command prompt with run as administrator

In my case, the issue was with my Xcode build scheme. When you run react-native run-ios you may see something like,

• info Found Xcode workspace "myproject.xcworkspace"*

• info Building (using "xcodebuild -workspace myproject.xcworkspace -configuration Debug -scheme myproject -destination id=xxxxxxxx-xxxxx-xxxxx-xxxx-xxxxxxxxx -derivedDataPath build/myproject")*

In this case, there should be a scheme named myproject in your ios configurations. The way I fixed it is,

Double clicked on myproject.xcworkspace in ios directory (to open workspace with Xcode)

Navigate into Product > Scheme > Manage Schemes...

Created a Scheme appropriately with name myproject (this name is case-sensitive)

Ran react-native run-ios in project directory

I was able to resolved this by enabling jedi in .vscode\settings.json

"python.jediEnabled": true

Reference from https://github.com/Microsoft/vscode-python/issues/3840#issuecomment-456017675

  rules: {'prettier/prettier': ['error', {endOfLine: 'auto'}]},
};

Interesting observation using Java 11 and switching off loop unrolling with the following VM option:

-XX:LoopUnrollLimit=0

The loop with the 2 * (i * i) expression results in more compact native code¹:

L0001: add    eax,r11d
       inc    r8d
       mov    r11d,r8d
       imul   r11d,r8d
       shl    r11d,1h
       cmp    r8d,r10d
       jl     L0001

in comparison with the 2 * i * i version:

L0001: add    eax,r11d
       mov    r11d,r8d
       shl    r11d,1h
       add    r11d,2h
       inc    r8d
       imul   r11d,r8d
       cmp    r8d,r10d

Here's a custom hook that I use which I believe is more intuitive than using usePrevious.

import { useRef, useEffect } from 'react'

// useTransition :: Array a => (a -> Void, a) -> Void
//                              |_______|  |
//                                  |      |
//                              callback  deps
//
// The useTransition hook is similar to the useEffect hook. It requires
// a callback function and an array of dependencies. Unlike the useEffect
// hook, the callback function is only called when the dependencies change.
// Hence, it's not called when the component mounts because there is no change
// in the dependencies. The callback function is supplied the previous array of
// dependencies which it can use to perform transition-based effects.
const useTransition = (callback, deps) => {
  const func = useRef(null)

  useEffect(() => {
    func.current = callback
  }, [callback])

  const args = useRef(null)

  useEffect(() => {
    if (args.current !== null) func.current(...args.current)
    args.current = deps
  }, deps)
}

You'd use useTransition as follows.

useTransition((prevRate, prevSendAmount, prevReceiveAmount) => {
  if (sendAmount !== prevSendAmount || rate !== prevRate && sendAmount > 0) {
    const newReceiveAmount = sendAmount * rate
    // do something
  } else {
    const newSendAmount = receiveAmount / rate
    // do something
  }
}, [rate, sendAmount, receiveAmount])

Hope that helps.

I was having this issue and nothing worked. I ran xcode-select --install and also installed /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg.

BACKGROUND

Since I was having issues with App Store on a new laptop, I was forced to download the Xcode Beta installer from the Apple website to install Xcode outside App Store. So I only had Xcode Beta installed.

SOLUTION

This, (I think), was making clang to not find the SDKROOT directory /Applications/Xcode.app/...., because there is no Beta in the path, or maybe Xcode Beta simply doesn't install it (I don't know). To fix the issue, I had to remove Xcode Beta and resolve the App Store issue to install the release version.

tldr;

If you have Xcode Beta, try cleaning up everything and installing the release version before trying out the solutions that are working for other people.

A little bit tricky to do something so simple but had no luck trying to reload and recreate the entire parent & child components with current solution.

Angular Router now provides strategy configuration to tell the Router what to do in case you navigate to the same URL as this user suggests in this GitHub issue.

First of all you can configure what to do while setting up the Router (your router module).

@NgModule({
   imports: [RouterModule.forRoot(routes, { onSameUrlNavigation: 'reload' })],
   exports: [RouterModule]
})

Or, if you are like me and don't want to change the entire router module behaviour you can do it with a method/function like this:

reloadComponent() {
    this._router.routeReuseStrategy.shouldReuseRoute = () => false;
    this._router.onSameUrlNavigation = 'reload';
    this._router.navigate(['/same-route']);
}

Of course you have to first inject Router in your component's constructor:

// import { Router } from '@angular/router';
...
constructor(private _router: Router){}
...

Somehow and as pointed out by @Abhiz you have to set shouldReuseRoute, with just configuring the Router by itself the page reload doesn't work with this aproach.

I've used an arrow function for shouldReuseRoutebecause new TSLint rules won't allow non-arrow functions.

As stated in the above answers, it's always a good practice to initialize the variables, but if you have something which you don't know what value should it takes, and you want to leave it uninitialized so you have to make sure that you are updating it before using it.

For example: Assume we have double _bmi; and you don't know what value should it takes, so you can leave it as it is, but before using it, you have to update its value first like calling a function that calculating BMI like follows:

String calculateBMI (){
_bmi = weight / pow( height/100, 2);
return _bmi.toStringAsFixed(1);}

or whatever, what I mean is, you can leave the variable as it is, but before using it make sure you have initialized it using whatever the method you are using.

Manually adding android.useAndroidX=true and android.enableJetifier=true giving me hard time. Because it's throw some error or Suggestion: add 'tools:replace="android:appComponentFactory"' to <application>

To Enable Jet-fire in project there is option in android Studio

Select Your Project ---> Right Click

app----> Refactor ----> Migrate to AndroidX

Shown in below image:-

After click on Migrate to AndroidX.

It will ask for confirmation and back up for your project.

And last step it will ask you for to do refactor.

After doing Refactor check your gradle.properties have android.useAndroidX=true and android.enableJetifier=true. If they are not then add these two lines to your gradle.properties file:

android.useAndroidX=true
android.enableJetifier=true

Note:- Upgrading using Android Studio, this option works if you have android studio 3.2 and onward. Check this

A Record lets you create a new type from a Union. The values in the Union are used as attributes of the new type.

For example, say I have a Union like this:

type CatNames = "miffy" | "boris" | "mordred";

Now I want to create an object that contains information about all the cats, I can create a new type using the values in the CatName Union as keys.

type CatList = Record<CatNames, {age: number}>

If I want to satisfy this CatList, I must create an object like this:

const cats:CatList = {
  miffy: { age:99 },
  boris: { age:16 },
  mordred: { age:600 }
}

You get very strong type safety:

• If I forget a cat, I get an error.
• If I add a cat that's not allowed, I get an error.
• If I later change CatNames, I get an error. This is especially useful because CatNames is likely imported from another file, and likely used in many places.

Real-world React example.

I used this recently to create a Status component. The component would receive a status prop, and then render an icon. I've simplified the code quite a lot here for illustrative purposes

I had a union like this:

type Statuses = "failed" | "complete";

I used this to create an object like this:

const icons: Record<
  Statuses,
  { iconType: IconTypes; iconColor: IconColors }
> = {
  failed: {
    iconType: "warning",
    iconColor: "red"
  },
  complete: {
    iconType: "check",
    iconColor: "green"
  };

I could then render by destructuring an element from the object into props, like so:

const Status = ({status}) => <Icon {...icons[status]} />

If the Statuses union is later extended or changed, I know my Status component will fail to compile and I'll get an error that I can fix immediately. This allows me to add additional error states to the app.

Note that the actual app had dozens of error states that were referenced in multiple places, so this type safety was extremely useful.

Install opencv-python (which is an unofficial pre-built OpenCV package for Python) by issuing the following command:

pip install opencv-python

This error can be due to many many things.

The key here seems the hint about error reading. I see you are working on a flash drive or something similar? Try to run the install on a local folder owned by your current user.

You could also try with sudo, that might solve a permission problem if that's the case.

Another reason why it cannot read could be because it has not downloaded correctly, or saved correctly. A little problem in your network could have caused that, and the cache clean would remove the files and force a refetch but that does not solve your problem. That means it would be more on the save part, maybe it didn't save because of permissions, maybe it didn't not save correctly because it was lacking disk space...

I had the same issue when using the alpine image.

My .sh file had the following first line:

#!/bin/bash

Alpine does not have bash. So changing the line to

#!/bin/sh

or installing bash with

apk add --no-cache bash

solved the issue for me.

This worked for me:

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

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

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

then in:

Run >> Edit Configurations

Add this line to VM Options:

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

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

implementation 'com.android.support:appcompat-v7:28.0' implementation 'com.android.support:support-media-compat:28.0.0' implementation 'com.android.support:support-v4:28.0.0' All to add

I'm facing exactly same error when I'm trying to clone a repository on a brand new machine. I'm using Git bash as my Git client. When I ran Git's command to clone a repository it was not prompting me for user id and password which will be used for authentication. It was a fresh machine where not a single credential was cached by Windows credential manager.

As a last resort, I manually added my credentials in credentials manager.

Go to > Control Panel\User Accounts\Credential Manager > Windows Credentials

Click Add a Windows credential link and then Supply the details as shown in the form below and you're done:

I had put the details as below:

Internet or network address: <gitRepoServerNameOrIPAddress>
User Name: MyCompanysDomainName\MyUserName
Password: MyPassword

Next time you run any Git command targeting a repository set up on above address this manually created credential will be used.

It is also important if you have a git command line you close it and reopen it for changes to be applied.

What fixed it for me was plugging my iPhone and allowing it as a simulator destination. Doing so required my to register my iPhone in Apple Dev account and once that was done and I ran my project from Xcode on my iPhone everything fixed itself.

1. Connect your iPhone to your Mac
2. Xcode>Window>Devices & Simulators
3. Add new under Devices and make sure "show are run destination" is ticked
4. Build project and run it on your iPhone

Use FirebaseMessaging instead

 FirebaseMessaging.getInstance().getToken()
    .addOnCompleteListener(new OnCompleteListener<String>() {
        @Override
        public void onComplete(@NonNull Task<String> task) {
          if (!task.isSuccessful()) {
            Log.w(TAG, "Fetching FCM registration token failed", task.getException());
            return;
          }

          // Get new FCM registration token
          String token = task.getResult();

          // Log and toast
          String msg = getString(R.string.msg_token_fmt, token);
          Log.d(TAG, msg);
          Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();
        }
    });

Perhaps the error message is somewhat misleading, but the gist is that X_train is a list, not a numpy array. You cannot use array indexing on it. Make it an array first:

out_images = np.array(X_train)[indices.astype(int)]

In windows, the command path must be redirected, for a default windows tesseract installation.

1. In 32 bit system, add in this line after import commands.

pytesseract.pytesseract.tesseract_cmd = 'C:\Program Files (x86)\Tesseract-OCR\tesseract.exe' 

2. In 64 bit system, add this line instead.

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

None of these answers worked for me. I had to use the command line:

mysql -u root db_name < db_dump.sql
SET NAMES 'utf8';
SOURCE db_dump.sql;

Done!

This can happen if your Android Gradle plugin is very old, even if you are only using a single Google lib! Apparently all Google libs used to need to be the exact same version. Now they don't need to be the same, only the latest. When specifying even a single lib, it pulls in dependencies where the versions don't match and the old Android Gradle plugin pukes.

Set a newer version like:

buildscript {
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.2'
    }
}

You may need update your Gradle to use the newer plugin (it will tell you).

This may be overkill for what you're looking for, but there is an npm package called marky that you can use to do this. It gives you a couple of extra features beyond just starting and stopping a timer. You just need to install it via npm and then import the dependency anywhere you'd like to use it. Here is a link to the npm package: https://www.npmjs.com/package/marky

An example of use after installing via npm would be as follows:

import * as _M from 'marky';

@Component({
 selector: 'app-test',
 templateUrl: './test.component.html',
 styleUrls: ['./test.component.scss']
})

export class TestComponent implements OnInit {
 Marky = _M;
}

constructor() {}

ngOnInit() {}

startTimer(key: string) {
 this.Marky.mark(key);
}

stopTimer(key: string) {
 this.Marky.stop(key);
}

key is simply a string which you are establishing to identify that particular measurement of time. You can have multiple measures which you can go back and reference your timer stats using the keys you create.

Use (on Linux): cd android ./gradlew assemblyRelease|assemblyDebug

An unsigned APK is generated for each case (for debug or testing)

NOTE: On Windows, replace gradle executable for gradlew.bat

I think best approach until Angular team add this feature to cli is first create angular (ng new something) in other place and then add what you want to delete. Using git to check witch files are changed or added by angular cli. then you can revert that changes. Be careful of untracked files from .gitignore.

Starting with MySQL 8 you no longer can (implicitly) create a user using the GRANT command. Use CREATE USER instead, followed by the GRANT statement:

mysql> CREATE USER 'root'@'%' IDENTIFIED BY 'root';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;

Caution about the security risks about WITH GRANT OPTION, see:

• Grant all privileges on database

ALTER USER 'mysqlUsername'@'localhost' IDENTIFIED WITH mysql_native_password BY 'mysqlUsernamePassword';

Remove quotes (') after ALTER USER and keep quote (') after mysql_native_password BY

It is working for me also.

To make the execution after the boolean has changed and avoid the usage of timeout you can do:

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

constructor(private cd: ChangeDetectorRef) {}

showSearch(){
  this.show = !this.show;  
  this.cd.detectChanges();
  this.searchElement.nativeElement.focus();
}

First find out your IP camera's streaming url, like whether it's RTSP/HTTP etc.

Code changes will be as follows:

cap = cv2.VideoCapture("ipcam_streaming_url")

For example:

cap = cv2.VideoCapture("http://192.168.18.37:8090/test.mjpeg")

Another idea: as long as the phpmyadmin and other php tools don't work with it, just add this line to your file /etc/mysql/my.cnf

default_authentication_plugin = mysql_native_password

See also: Mysql Ref

I know that this is a security issue, but what to do if the tools don't work with caching_sha2_password?

I met the same error on Windows when I tried to install a package via pip3:

Traceback (most recent call last):
  File "d:\anaconda\lib\runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  File "d:\anaconda\lib\runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "D:\Anaconda\Scripts\pip3.6.exe\__main__.py", line 5, in <module>
ModuleNotFoundError: No module named 'pip._internal'

My python is installed via Anaconda. I solved this issue by reinstalling pip via conda:

conda install pip

After that, pip returns to normal.

For me this issue occured when I was running python while within my site-packages folder. If I ran it anywhere else, it was no longer an issue.

In flutter if you want to do conditional rendering, you may do this:

Column(
   children: <Widget>[
     if (isCondition == true)
        Text('The condition is true'),
   ],
 );

But what if you want to use a tertiary (if-else) condition? when the child widget is multi-layered.

You can use this for its solution flutter_conditional_rendering a flutter package which enhances conditional rendering, supports if-else and switch conditions.

If-Else condition:

Column(
      children: <Widget>[
        Conditional.single(
          context: context,
          conditionBuilder: (BuildContext context) => someCondition == true,
          widgetBuilder: (BuildContext context) => Text('The condition is true!'),
          fallbackBuilder: (BuildContext context) => Text('The condition is false!'),
        ),
      ],
    );

Switch condition:

Column(
      children: <Widget>[
        ConditionalSwitch.single<String>(
          context: context,
          valueBuilder: (BuildContext context) => 'A',
          caseBuilders: {
            'A': (BuildContext context) => Text('The value is A!'),
            'B': (BuildContext context) => Text('The value is B!'),
          },
          fallbackBuilder: (BuildContext context) => Text('None of the cases matched!'),
        ),
      ],
    );

If you want to conditionally render a list of widgets (List<Widget>) instead of a single one. Use Conditional.list() and ConditionalSwitch.list()!

I assume you're seeing this in a React component's render method, like this (edit: your edited question does indeed show that):

class Example extends React.Component {_x000D_
  render() {_x000D_
    return <div>_x000D_
      <div>Children ({this.props.children.length}):</div>_x000D_
      {this.props.children}_x000D_
    </div>;_x000D_
  }_x000D_
}_x000D_
_x000D_
class Widget extends React.Component {_x000D_
  render() {_x000D_
    return <div>_x000D_
      <div>First <code>Example</code>:</div>_x000D_
      <Example>_x000D_
        <div>1</div>_x000D_
        <div>2</div>_x000D_
        <div>3</div>_x000D_
      </Example>_x000D_
      <div>Second <code>Example</code> with different children:</div>_x000D_
      <Example>_x000D_
        <div>A</div>_x000D_
        <div>B</div>_x000D_
      </Example>_x000D_
    </div>;_x000D_
  }_x000D_
}_x000D_
_x000D_
ReactDOM.render(_x000D_
  <Widget/>,_x000D_
  document.getElementById("root")_x000D_
);

<div id="root"></div>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>_x000D_

children is a special property of React components which contains any child elements defined within the component, e.g. the divs inside Example above. {this.props.children} includes those children in the rendered result.

...what are the situations to use the same

You'd do it when you want to include the child elements in the rendered output directly, unchanged; and not if you didn't.

I had the same issue and I fixed it this way:

1. Deleted all projects from eclipse, not from the computer.
2. Created a new project and as soon as you write the name of your project, you get another window, in which is written: "Create module-info.java". I just clicked "don't create".
3. Created a package. Let us call the package mywork.
4. Created a Java class inside the package myWork. Let us call the class HelloWorld.
5. I run the file normally and it was working fine.

Note: First, make sure that Java is running properly using the CMD command in that way you will understand the problem is on eclipse and not on JDK.

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

You can see the button "Code" in the attached screenshot, press it and you can get your code in many different languages including PHP cURL

You can set also blank condition, in place of set null

         var isDisable=true;

   

          RaisedButton(
              padding: const EdgeInsets.all(20),
              textColor: Colors.white,
              color: Colors.green,
              onPressed:  isDisable
                  ? () => (){} : myClickingData(),
              child: Text('Button'),
            )

The issue could be with the response you are receiving from back-end. If it was working fine on the server then the problem could be with the response headers. Check the Access-Control-Allow-Origin (ACAO) in the response headers. Usually react's fetch API will throw fail to fetch even after receiving response when the response headers' ACAO and the origin of request won't match.

After making sure your environment is not active, type:

$ conda env remove --name ENVIRONMENT

I tried your code, you didn't assign/bind a value to your formControlName.

In HTML file:

<form [formGroup]="form">
   <label>
     <input type="radio" value="Male" formControlName="gender">
       <span>male</span>
   </label>
   <label>
     <input type="radio" value="Female" formControlName="gender">
       <span>female</span>
   </label>
</form>

In the TS file:

  form: FormGroup;
  constructor(fb: FormBuilder) {
    this.name = 'Angular2'
    this.form = fb.group({
      gender: ['', Validators.required]
    });
  }

Make sure you use Reactive form properly: [formGroup]="form" and you don't need the name attribute.

In my sample. words male and female in span tags are the values display along the radio button and Male and Female values are bind to formControlName

See the screenshot:

To make it shorter:

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

Hope it helps:)

If the emulator is running and is not being detected by the flutter and adb devices then try connecting it manually by using the following command

abd connect 127.0.0.1:62001

If it fails to connect, try again. The following message should appear

connected to 127.0.0.1:62001

Then try flutter doctor or adb devices to make sure it has been connected successfully.

For Gradle with Kotlin language (*.gradle.kts files), add this:

android {
    [...]
    kotlinOptions {
        this as KotlinJvmOptions
        jvmTarget = "1.8"
    }
}

Same problem here, it turned out to be my incorrectly configured proxy settings, here's how to check and remove them.

First open your git config file.

vi ~/.gitconfig

and find out whether the [http] or [https] sections are set.

I used to set proxies for git due to slow access to Github in China, however, lately I changed my local proxy ports but I forgot my git settings.

If you have incorrect proxy settings and decide to remove it, simply execute:

git config --global --unset http.proxy
git config --global --unset https.proxy

Things will work just fine.

f = open("Path/To/Your/File.txt", "w")   # 'r' for reading and 'w' for writing
f.write("Hello World from " + f.name)    # Write inside file 
f.close()                                # Close file 

# Method 2shush
with open("Path/To/Your/File.txt", "w") as f:   # Opens file and casts as f 
    f.write("Hello World form " + f.name)       # Writing
# File closed automatically

You can always try Manage Docker as a non-root user paragraph in the https://docs.docker.com/install/linux/linux-postinstall/ docs.

After doing this also if the problem persists then you can run the following command to solve it:

sudo chmod 666 /var/run/docker.sock

Just default the variable to the expected type:

(number=1) => ...
(number=1.0) => ...
(string='str') ...

you can use SemaphoreSlim to block the next thread that will try to execute that EF call.

static SemaphoreSlim semSlim = new SemaphoreSlim(1, 1);

await semSlim.WaitAsync();
try
{
  // something like this here...
  // EmployeeService.GetList(); or...
  var result = await _ctx.Employees.ToListAsync();
}
finally
{
  semSlim.Release();
}

I am using python 3.6.8, on ubunu 18.04, for me the solution was to just upgrade pip

pip install --upgrade pip
pip install tensorflow==2.1.0

If you don't have an image with that name locally, docker will try to pull it from docker hub, but there's no such image on docker hub. Or simply try "docker login".

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

Once I used double slash while calling the API then I got the same error.

I had to call http://localhost:8080/getSomething but I did Like http://localhost:8080//getSomething. I resolved it by removing extra slash.

If you want to use default mailtrip.io you don't need to modify mail.php file.

1. Create account on mailtrip.io
2. Go to Inboxes > My Inbox > SMTP Settings > Integration Laravel
3. Modify .env file and replace all nulls of correct credentials:

MAIL_HOST=smtp.mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null

4. Run:

php artisan config:cache

When you want a flex item to occupy an entire row, set it to width: 100% or flex-basis: 100%, and enable wrap on the container.

The item now consumes all available space. Siblings are forced on to other rows.

.parent {
  display: flex;
  flex-wrap: wrap;
}

#range, #text {
  flex: 1;
}

.error {
  flex: 0 0 100%; /* flex-grow, flex-shrink, flex-basis */
  border: 1px dashed black;
}

<div class="parent">
  <input type="range" id="range">
  <input type="text" id="text">
  <label class="error">Error message (takes full width)</label>
</div>

More info: The initial value of the flex-wrap property is nowrap, which means that all items will line up in a row. MDN

I had the same problem and none of the above answers worked. If you go into the settings (CTRL + ALT + s) and search for project interpreter you will see all of the installed packages. Click the + button at the top right and search for xlrd, then click install package at the bottom left.

I had already done the "pip install xlrd" command from the file location of my python.exe before this, so you may need to do that as well. (you can find the file location by searching it in windows search bar and right click -> open file location, then type cmd into the file explorer address bar)

I had this due to a simple ordering mistake on my end. I called

[WRONG] docker run <image> <arguments> <command>

When I should have used

docker run <arguments> <image> <command>

Same resolution on similar question: https://stackoverflow.com/a/50762266/6278

In my case, The issue was that for UAT environment, API URL will start with Http instead of https. Also, the backend assigns different ports for both Http and https.

for example,

http://10.12.12.31:2001/api/example. - is correct for me

https://10.12.12.31:2002/api/example. - is wrong for me

Because I was using https and 2002 port for hitting the UAT environment. So I am getting could not get any response error in postman.

This happens because your local module named urllib.py shadows the installed requests module you are trying to use. The current directory is preapended to sys.path, so the local name takes precedence over the installed name.

An extra debugging tip when this comes up is to look at the Traceback carefully, and realize that the name of your script in question is matching the module you are trying to import.

Rename your file to something else like url.py. Then It is working fine. Hope it helps!

You can post axios data by using FormData() like:

var bodyFormData = new FormData();

And then add the fields to the form you want to send:

bodyFormData.append('userName', 'Fred');

If you are uploading images, you may want to use .append

bodyFormData.append('image', imageFile); 

And then you can use axios post method (You can amend it accordingly)

axios({
  method: "post",
  url: "myurl",
  data: bodyFormData,
  headers: { "Content-Type": "multipart/form-data" },
})
  .then(function (response) {
    //handle success
    console.log(response);
  })
  .catch(function (response) {
    //handle error
    console.log(response);
  });

Can't get a .post with 'Content-Type': 'multipart/form-data' to work @ axios/axios

This answer is for anyone encountering pdfs with images and needing to use OCR. I could not find a workable off-the-shelf solution; nothing that gave me the accuracy I needed.

Here are the steps I found to work.

1. Use pdfimages from https://poppler.freedesktop.org/ to turn the pages of the pdf into images.

2. Use Tesseract to detect rotation and ImageMagick mogrify to fix it.

3. Use OpenCV to find and extract tables.

4. Use OpenCV to find and extract each cell from the table.

5. Use OpenCV to crop and clean up each cell so that there is no noise that will confuse OCR software.

6. Use Tesseract to OCR each cell.

7. Combine the extracted text of each cell into the format you need.

I wrote a python package with modules that can help with those steps.

Repo: https://github.com/eihli/image-table-ocr

Docs & Source: https://eihli.github.io/image-table-ocr/pdf_table_extraction_and_ocr.html

Some of the steps don't require code, they take advantage of external tools like pdfimages and tesseract. I'll provide some brief examples for a couple of the steps that do require code.

2. Finding tables:

This link was a good reference while figuring out how to find tables. https://answers.opencv.org/question/63847/how-to-extract-tables-from-an-image/

import cv2

def find_tables(image):
    BLUR_KERNEL_SIZE = (17, 17)
    STD_DEV_X_DIRECTION = 0
    STD_DEV_Y_DIRECTION = 0
    blurred = cv2.GaussianBlur(image, BLUR_KERNEL_SIZE, STD_DEV_X_DIRECTION, STD_DEV_Y_DIRECTION)
    MAX_COLOR_VAL = 255
    BLOCK_SIZE = 15
    SUBTRACT_FROM_MEAN = -2

    img_bin = cv2.adaptiveThreshold(
        ~blurred,
        MAX_COLOR_VAL,
        cv2.ADAPTIVE_THRESH_MEAN_C,
        cv2.THRESH_BINARY,
        BLOCK_SIZE,
        SUBTRACT_FROM_MEAN,
    )
    vertical = horizontal = img_bin.copy()
    SCALE = 5
    image_width, image_height = horizontal.shape
    horizontal_kernel = cv2.getStructuringElement(cv2.MORPH_RECT, (int(image_width / SCALE), 1))
    horizontally_opened = cv2.morphologyEx(img_bin, cv2.MORPH_OPEN, horizontal_kernel)
    vertical_kernel = cv2.getStructuringElement(cv2.MORPH_RECT, (1, int(image_height / SCALE)))
    vertically_opened = cv2.morphologyEx(img_bin, cv2.MORPH_OPEN, vertical_kernel)

    horizontally_dilated = cv2.dilate(horizontally_opened, cv2.getStructuringElement(cv2.MORPH_RECT, (40, 1)))
    vertically_dilated = cv2.dilate(vertically_opened, cv2.getStructuringElement(cv2.MORPH_RECT, (1, 60)))

    mask = horizontally_dilated + vertically_dilated
    contours, hierarchy = cv2.findContours(
        mask, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE,
    )

    MIN_TABLE_AREA = 1e5
    contours = [c for c in contours if cv2.contourArea(c) > MIN_TABLE_AREA]
    perimeter_lengths = [cv2.arcLength(c, True) for c in contours]
    epsilons = [0.1 * p for p in perimeter_lengths]
    approx_polys = [cv2.approxPolyDP(c, e, True) for c, e in zip(contours, epsilons)]
    bounding_rects = [cv2.boundingRect(a) for a in approx_polys]

    # The link where a lot of this code was borrowed from recommends an
    # additional step to check the number of "joints" inside this bounding rectangle.
    # A table should have a lot of intersections. We might have a rectangular image
    # here though which would only have 4 intersections, 1 at each corner.
    # Leaving that step as a future TODO if it is ever necessary.
    images = [image[y:y+h, x:x+w] for x, y, w, h in bounding_rects]
    return images

3. Extract cells from table.

This is very similar to 2, so I won't include all the code. The part I will reference will be in sorting the cells.

We want to identify the cells from left-to-right, top-to-bottom.

We’ll find the rectangle with the most top-left corner. Then we’ll find all of the rectangles that have a center that is within the top-y and bottom-y values of that top-left rectangle. Then we’ll sort those rectangles by the x value of their center. We’ll remove those rectangles from the list and repeat.

def cell_in_same_row(c1, c2):
    c1_center = c1[1] + c1[3] - c1[3] / 2
    c2_bottom = c2[1] + c2[3]
    c2_top = c2[1]
    return c2_top < c1_center < c2_bottom

orig_cells = [c for c in cells]
rows = []
while cells:
    first = cells[0]
    rest = cells[1:]
    cells_in_same_row = sorted(
        [
            c for c in rest
            if cell_in_same_row(c, first)
        ],
        key=lambda c: c[0]
    )

    row_cells = sorted([first] + cells_in_same_row, key=lambda c: c[0])
    rows.append(row_cells)
    cells = [
        c for c in rest
        if not cell_in_same_row(c, first)
    ]

# Sort rows by average height of their center.
def avg_height_of_center(row):
    centers = [y + h - h / 2 for x, y, w, h in row]
    return sum(centers) / len(centers)

rows.sort(key=avg_height_of_center)

If the requested resource of the server is using Flask. Install Flask-CORS.

you have defined the public dir in app root/public

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

so you have to use:

./css/main.css

goto Android->sdk->build-tools directory make sure you have all the versions required . if not , download them . after that goto File-->Settigs-->Build,Execution,Depoyment-->Gradle

choose use default gradle wapper (recommended)

and untick Offline work

gradle build finishes successfully for once you can change the settings

If it dosent simply solve the problem

check this link to find an appropriate support library revision

https://developer.android.com/topic/libraries/support-library/revisions

Make sure that the compile sdk and target version same as the support library version. It is recommended maintain network connection atleast for the first time build (Remember to rebuild your project after doing this)

We love Kubernetes is because once we give them what we want it goes on to figure out how to achieve it without our any involvement.

"create" is like playing GOD by taking things into our own hands. It is good for local debugging when you only want to work with the POD and not care abt Deployment/Replication Controller.

"apply" is playing by the rules. "apply" is like a master tool that helps you create and modify and requires nothing from you to manage the pods.

if you have null value then in doing mathematical operation you will get this error to resolve it use df[~df['x'].isnull()]df[['x']].astype(int) if you want your dataset to be unchangeable.

this worked for me

// using Microsoft.AspNetCore.Authentication.Cookies;
// using Microsoft.AspNetCore.Http;

services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
    .AddCookie(CookieAuthenticationDefaults.AuthenticationScheme,
        options =>
        {
            options.LoginPath = new PathString("/auth/login");
            options.AccessDeniedPath = new PathString("/auth/denied");
        });

What I did was I uninstalled Java from my PC, and then downloaded and installed JDK again from Oracle. After this it worked perfectly. I think the problem was because the JRE and JDK update version were different from each other.

UPDATE for Bootstrap 4 stable

The cursor: pointer; rule has been restored, so buttons will now by default have the cursor on hover:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">_x000D_
<button type="button" class="btn btn-success">Sample Button</button>

No, there isn't. You need to make some custom CSS for this.

If you just need a link that looks like a button (with pointer), use this:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css">_x000D_
<a class="btn btn-success" href="#" role="button">Sample Button</a>

You can use window.location.reload(); in your componentDidMount() lifecycle method. If you are using react-router, it has a refresh method to do that.

Edit: If you want to do that after a data update, you might be looking to a re-render not a reload and you can do that by using this.setState(). Here is a basic example of it to fire a re-render after data is fetched.

import React from 'react'

const ROOT_URL = 'https://jsonplaceholder.typicode.com';
const url = `${ROOT_URL}/users`;

class MyComponent extends React.Component {
    state = {
        users: null
    }
    componentDidMount() {
        fetch(url)
            .then(response => response.json())
            .then(users => this.setState({users: users}));
    }
    render() {
        const {users} = this.state;
        if (users) {
            return (
                <ul>
                    {users.map(user => <li>{user.name}</li>)}
                </ul>
            )
        } else {
            return (<h1>Loading ...</h1>)
        }
    }
}

export default MyComponent;

Use multiDexEnabled true as below.

{
 minSdkVersion 17
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
}

and

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

this Solution worked for me.

I have the same problem while learning Node.js Here is my solution for it to install jquery

npm install [email protected] --save
npm install popper.js@^1.12.9 --save

As I got this case at my own and the answers here didn't help me, my situation was because of I downgraded the targetSdkVersion in gradle app module file from 24 to 22 for some reason, and apparently the apk doesn't accept another one with downgraded targetSdkVersion to be installed over it.

So, once I changed it back to 24 the error disappeared and app installed correctly.

If you want to hide this warn, you just need to install fsevents as a optional dependency. Just execute:

npm i fsevents@latest -f --save-optional

..And the warn will no longer be a bother.

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

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

I had accidentally removed the matInput directive from the input field which caused the same error.

eg.

<mat-form-field>
   <input [readOnly]="readOnly" name="amount" formControlName="amount" placeholder="Amount">
</mat-form-field>

fixed code

 <mat-form-field>
   <input matInput [readOnly]="readOnly" name="amount" formControlName="amount" placeholder="Amount">
</mat-form-field>

You could try the following:

import matplotlib.pyplot as plt
import numpy as np

def plot_figures(figures, nrows = 1, ncols=1):
    """Plot a dictionary of figures.

    Parameters
    ----------
    figures : <title, figure> dictionary
    ncols : number of columns of subplots wanted in the display
    nrows : number of rows of subplots wanted in the figure
    """

    fig, axeslist = plt.subplots(ncols=ncols, nrows=nrows)
    for ind,title in zip(range(len(figures)), figures):
        axeslist.ravel()[ind].imshow(figures[title], cmap=plt.jet())
        axeslist.ravel()[ind].set_title(title)
        axeslist.ravel()[ind].set_axis_off()
    plt.tight_layout() # optional



# generation of a dictionary of (title, images)
number_of_im = 20
w=10
h=10
figures = {'im'+str(i): np.random.randint(10, size=(h,w)) for i in range(number_of_im)}

# plot of the images in a figure, with 5 rows and 4 columns
plot_figures(figures, 5, 4)

plt.show()

However, this is basically just copy and paste from here: Multiple figures in a single window for which reason this post should be considered to be a duplicate.

I hope this helps.

function omit(obj, key) {
    const {[key]:ignore, ...rest} = obj;
    return rest;
}

You can use ES6 spread operators like this. And to remove your key simply call

const newJson = omit(myjsonobj, "otherIndustry");

Its always better if you maintain pure function when you deal with type=object in javascript.

In Windows 64, if you did this sequence correctly:

Anaconda prompt:

conda create -n tensorflow python=3.5
activate tensorflow
pip install --ignore-installed --upgrade tensorflow

Be sure you still are in tensorflow environment. The best way to make Spyder recognize your tensorflow environment is to do this:

conda install spyder

This will install a new instance of Spyder inside Tensorflow environment. Then you must install scipy, matplotlib, pandas, sklearn and other libraries. Also works for OpenCV.

Always prefer to install these libraries with "conda install" instead of "pip".

I also had the same error , angular 7

 <button (click)="Addcity(city.name)" [(ngModel)]="city.name"  class="dropdown-item fontstyle"
     *ngFor="let city of Cities; let i = index">
      {{city.name}}
 </button>

I just added ngDefaultControl

   <button (click)="Addcity(city.name)" [(ngModel)]="city.name"  ngDefaultControl class="dropdown-item fontstyle"
 *ngFor="let city of Cities; let i = index">
  {{city.name}}

Try to run

npm i node-sass@latest

CSS

In CSS we write code as depicted bellow, in full length.

body{
 width: 800px;
 color: #ffffff;
}
body content{
 width:750px;
 background:#ffffff;
}

SCSS

In SCSS we can shorten this code using a @mixin so we don’t have to write color and width properties again and again. We can define this through a function, similarly to PHP or other languages.

$color: #ffffff;
$width: 800px;

@mixin body{
 width: $width;
 color: $color;

 content{
  width: $width;
  background:$color;
 }
}

SASS

In SASS however, the whole structure is visually quicker and cleaner than SCSS.

• It is sensitive to white space when you are using copy and paste,

• It seems that it doesn't support inline CSS currently.

  $color: #ffffff
  $width: 800px
  $stack: Helvetica, sans-serif
  
  body
    width: $width
    color: $color
    font: 100% $stack
  
    content
      width: $width
      background:$color
  

Your installation is wrong; you are using a very old compiler version (1.0.3.0).

tsc --version should return a version of 2.5.2.

Check where that old compiler is located using: which tsc (or where tsc) and remove it.

Try uninstalling the "global" typescript

npm uninstall -g typescript

Installing as part of a local dev dependency of your project

npm install typescript --save-dev

Execute it from the root of your project

./node_modules/.bin/tsc

    <div class="col-md-12">
      <p style="color: #28a745; font-weight: bold; font-size:25px; text-align: right " >Total Productos a pagar= {{ getTotal() }} {{ getResult() | currency }}

JSX tags (<Component/>) are clearly not standard javascript and have no special meaning if you put them inside a naked <script> tag for example. Hence all React files that contain them are JSX and not JS.

By convention, the entry point of a React application is usually .js instead of .jsx even though it contains React components. It could as well be .jsx. Any other JSX files usually have the .jsx extension.

In any case, the reason there is ambiguity is because ultimately the extension does not matter much since the transpiler happily munches any kinds of files as long as they are actually JSX.

My advice would be: don't worry about it.

You can write:

python
import keras
keras.__version__

https://router.vuejs.org/en/api/router-link.html add attribute active-class="active" eg:

<ul class="nav navbar-nav">
    <router-link tag="li" active-class="active" to="/" exact><a>Home</a></router-link>
    <router-link tag="li" active-class="active" to="/about"><a>About</a></router-link>
    <router-link tag="li" active-class="active" to="/permission-list"><a>Permisison</a></router-link>

I'm using VsCode and solved this issue by stopping the application server and them run npm install. There are files that were locked by the application server.

No need to close the IDE, just make sure there's no another process locking some files on your projects.

The other way to tackle it is to use this code snippet:

JSON.parse(JSON.stringify(response)).data

This feels so wrong but it works

First of all, CORS is definitely a server-side problem and not client-side but I was more than sure that server code was correct in my case since other apps were working using the same server on different domains. The solution for this described in more details in other answers.

My problem started when I started using axios with my custom instance. In my case, it was a very specific problem when we use a baseURL in axios instance and then try to make GET or POST calls from anywhere, axios adds a slash / between baseURL and request URL. This makes sense too, but it was the hidden problem. My Laravel server was redirecting to remove the trailing slash which was causing this problem.

In general, the pre-flight OPTIONS request doesn't like redirects. If your server is redirecting with 301 status code, it might be cached at different levels. So, definitely check for that and avoid it.

Oneliner to solve your problem. I assume you will store your URL in myURL string. Add this line and you are done. myURL = myURL.replace("http", "https");

Trust me, this will work for you:

    npm config set registry http://registry.npmjs.org/  

My machine is Windows 10, I've faced similar problems while tried to compile SASS using node-sass package. My node version is v10.16.3 and npm version is 6.9.0

The way that I resolved the problem:

1. At first delete package-lock.json file and node_modules/ folder.
2. Open Windows PowerShell as Administrator.
3. Run the command npm i -g node-sass.
4. After that, go to the project folder and run npm install
5. And finally, run the SASS compiling script, in my case, it is npm run build:css

And it works!!

I discovered the joy of anaconda: https://www.continuum.io/downloads

C:> conda create -n tensorflow1.1 python=3.5
C:> activate tensorflow1.1
(tensorflow1.1) 
C:> pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/windows/gpu/tensorflow_gpu-1.1.0-cp35-cp35m-win_amd64.whl

voila, a virtual environment is created.

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.

In my case I was using version 17.0.1 .It was showing error.

implementation "com.google.android.gms:play-services-location:17.0.1"

After changing version to 17.0.0, it worked

implementation "com.google.android.gms:play-services-location:17.0.0"

Reason might be I was using maps dependency of version 17.0.0 & location version as 17.0.1.It might have thrown error.So,try to maintain consistency in version numbers.

I deleted any existing popper directories, then ran

npm install --save popper.js angular-popper

Possible way is (sure you can change array declaration to getting from db or another external resource):

const MyPosts = () => {

  let postsRawData = [
    { id: 1, text: 'Post 1', likesCount: '1' },
    { id: 2, text: 'Post 2', likesCount: '231' },
    { id: 3, text: 'Post 3', likesCount: '547' }
  ];

  const postsItems = []
  for (const [key, value] of postsRawData.entries()) {
    postsItems.push(<Post text={value.text} likesCount={value.likesCount} />)
  }

  return (
      <div className={css.posts}>Posts:
          {postsItems}
      </div>
  )
}

*NgIf can create problem here , so either use display none css or easier way is to Use [hidden]="!condition"

_{In general, to set a video's FPS to 24, almost always you can do:}

With Audio and without re-encoding:

# Extract video stream
ffmpeg -y -i input_video.mp4 -c copy -f h264 output_raw_bitstream.h264
# Extract audio stream
ffmpeg -y -i input_video.mp4 -vn -acodec copy output_audio.aac
# Remux with new FPS 
ffmpeg -y -r 24 -i output_raw_bitstream.h264 -i output-audio.aac -c copy output.mp4

If you want to find the video format (H264 in this case), you can use FFprobe, like this

ffprobe -loglevel error -select_streams v -show_entries stream=codec_name -of default=nw=1:nk=1 input_video.mp4

which will output:

h264

Read more in How can I analyze file and detect if the file is in H.264 video format?

With re-encoding:

ffmpeg -y -i input_video.mp4 -vf -r 24 output.mp4

Simple Sample

    public void showNotification (String from, String notification, Intent intent) {
        PendingIntent pendingIntent = PendingIntent.getActivity(
                context,
                Notification_ID,
                intent,
                PendingIntent.FLAG_UPDATE_CURRENT
        );


        String NOTIFICATION_CHANNEL_ID = "my_channel_id_01";
        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);


        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "My Notifications", NotificationManager.IMPORTANCE_DEFAULT);

            // Configure the notification channel.
            notificationChannel.setDescription("Channel description");
            notificationChannel.enableLights(true);
            notificationChannel.setLightColor(Color.RED);
            notificationChannel.setVibrationPattern(new long[]{0, 1000, 500, 1000});
            notificationChannel.enableVibration(true);
            notificationManager.createNotificationChannel(notificationChannel);
        }


        NotificationCompat.Builder builder = new NotificationCompat.Builder(context, NOTIFICATION_CHANNEL_ID);
        Notification mNotification = builder
                .setContentTitle(from)
                .setContentText(notification)

//                .setTicker("Hearty365")
//                .setContentInfo("Info")
                //     .setPriority(Notification.PRIORITY_MAX)

                .setContentIntent(pendingIntent)

                .setAutoCancel(true)
//                .setDefaults(Notification.DEFAULT_ALL)
//                .setWhen(System.currentTimeMillis())
                .setSmallIcon(R.mipmap.ic_launcher)
                .setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.mipmap.ic_launcher))
                .build();

        notificationManager.notify(/*notification id*/Notification_ID, mNotification);

    }

Just use special `

var lyrics = 'Never gonna give you up';
var html = `<div>${lyrics}</div>`;

You can see more examples here.

You can use a join to do this

SELECT t1.* from myTable t1
LEFT OUTER JOIN myTable t2 on t2.ID=t1.ID AND t2.`Date` > t1.`Date`
WHERE t2.`Date` IS NULL;

Only rows which have the latest date for each ID with have a NULL join to t2.

To update container-selinux I had to install epel-release first:

Add Centos-7 repository

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

Install epel-release

yum install epel-release

Update container-selinux

yum install container-selinux

The image you're using is Alpine based, so you can't use apt-get because it's Ubuntu's package manager.

To fix this just use:

apk update and apk add

Install pylint-django using pip as follows

pip install pylint-django

Then in Visual Studio Code goto: User Settings (Ctrl + , or File > Preferences > Settings if available ) Put in the following (please note the curly braces which are required for custom user settings in VSC):

{"python.linting.pylintArgs": [
     "--load-plugins=pylint_django"
],}

For those experiencing this error on CI/CD, adding the line below worked for me on my GitHub Actions CI/CD workflow right after running pip install pyflakes diff-cover:

git fetch origin master:refs/remotes/origin/master

This is a snippet of the solution from the diff-cover github repo:

Solution: diff-cover matches source files in the coverage XML report with source files in the git diff. For this reason, it's important that the relative paths to the files match. If you are using coverage.py to generate the coverage XML report, then make sure you run diff-cover from the same working directory.

I got the solution on the links below. It is a documented diff-cover error.

https://diff-cover.readthedocs.io/en/latest//README.html https://github.com/Bachmann1234/diff_cover/blob/master/README.rst

Hope this helps :-).

There are a few reasons that ESLint may not be giving you feedback. ESLint is going to look for your configuration file first in your project and if it can't find a .eslintrc.json there it will look for a global configuration. Personally, I only install ESLint in each project and create a configuration based off of each project.

The second reason why you aren't getting feedback is that to get the feedback you have to define your linting rules in the .eslintrc.json. If there are no rules there, or you have no plugins installed then you have to define them.

It is possible to use your usual System.Configuration even in .NET Core 2.0 on Linux. Try this test example:

1. Created a .NET Standard 2.0 Library (say MyLib.dll)
2. Added the NuGet package System.Configuration.ConfigurationManager v4.4.0. This is needed since this package isn't covered by the meta-package NetStandard.Library v2.0.0 (I hope that changes)
3. All your C# classes derived from ConfigurationSection or ConfigurationElement go into MyLib.dll. For example MyClass.cs derives from ConfigurationSection and MyAccount.cs derives from ConfigurationElement. Implementation details are out of scope here but Google is your friend.
4. Create a .NET Core 2.0 app (e.g. a console app, MyApp.dll). .NET Core apps end with .dll rather than .exe in Framework.
5. Create an app.config in MyApp with your custom configuration sections. This should obviously match your class designs in #3 above. For example:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <section name="myCustomConfig" type="MyNamespace.MyClass, MyLib" />
  </configSections>
  <myCustomConfig>
    <myAccount id="007" />
  </myCustomConfig>
</configuration>

That's it - you'll find that the app.config is parsed properly within MyApp and your existing code within MyLib works just fine. Don't forget to run dotnet restore if you switch platforms from Windows (dev) to Linux (test).

Additional workaround for test projects

If you're finding that your App.config is not working in your test projects, you might need this snippet in your test project's .csproj (e.g. just before the ending </Project>). It basically copies App.config into your output folder as testhost.dll.config so dotnet test picks it up.

  <!-- START: This is a buildtime work around for https://github.com/dotnet/corefx/issues/22101 -->
  <Target Name="CopyCustomContent" AfterTargets="AfterBuild">
    <Copy SourceFiles="App.config" DestinationFiles="$(OutDir)\testhost.dll.config" />
  </Target>
  <!-- END: This is a buildtime work around for https://github.com/dotnet/corefx/issues/22101 -->

navigateByUrl

routerLink directive as used like this:

<a [routerLink]="/inbox/33/messages/44">Open Message 44</a>

is just a wrapper around imperative navigation using router and its navigateByUrl method:

router.navigateByUrl('/inbox/33/messages/44')

as can be seen from the sources:

export class RouterLink {
  ...

  @HostListener('click')
  onClick(): boolean {
    ...
    this.router.navigateByUrl(this.urlTree, extras);
    return true;
  }

So wherever you need to navigate a user to another route, just inject the router and use navigateByUrl method:

class MyComponent {
   constructor(router: Router) {
      this.router.navigateByUrl(...);
   }
}

navigate

There's another method on the router that you can use - navigate:

router.navigate(['/inbox/33/messages/44'])

difference between the two

Using router.navigateByUrl is similar to changing the location bar directly–we are providing the “whole” new URL. Whereas router.navigate creates a new URL by applying an array of passed-in commands, a patch, to the current URL.

To see the difference clearly, imagine that the current URL is '/inbox/11/messages/22(popup:compose)'.

With this URL, calling router.navigateByUrl('/inbox/33/messages/44') will result in '/inbox/33/messages/44'. But calling it with router.navigate(['/inbox/33/messages/44']) will result in '/inbox/33/messages/44(popup:compose)'.

(change) event bound to classical input change event.

https://developer.mozilla.org/en-US/docs/Web/Events/change

You can use (change) event even if you don't have a model at your input as

<input (change)="somethingChanged()">

(ngModelChange) is the @Output of ngModel directive. It fires when the model changes. You cannot use this event without ngModel directive.

https://github.com/angular/angular/blob/master/packages/forms/src/directives/ng_model.ts#L124

As you discover more in the source code, (ngModelChange) emits the new value.

https://github.com/angular/angular/blob/master/packages/forms/src/directives/ng_model.ts#L169

So it means you have ability of such usage:

<input (ngModelChange)="modelChanged($event)">

modelChanged(newObj) {
    // do something with new value
}

Basically, it seems like there is no big difference between two, but ngModel events gains the power when you use [ngValue].

  <select [(ngModel)]="data" (ngModelChange)="dataChanged($event)" name="data">
      <option *ngFor="let currentData of allData" [ngValue]="currentData">
          {{data.name}}
      </option>
  </select>

dataChanged(newObj) {
    // here comes the object as parameter
}

assume you try the same thing without "ngModel things"

<select (change)="changed($event)">
    <option *ngFor="let currentData of allData" [value]="currentData.id">
        {{data.name}}
    </option>
</select>

changed(e){
    // event comes as parameter, you'll have to find selectedData manually
    // by using e.target.data
}

you can also use a hashmap for this

@GetMapping
public HashMap<String, Object> get() {
    HashMap<String, Object> map = new HashMap<>();
    map.put("key1", "value1");
    map.put("results", somePOJO);
    return map;
}

you need object notation

<section [ngClass]="{'class1':condition1, 'class2': condition2, 'class3':condition3}" > 

ref: NgClass

Got the same error when I tried to run add-migration. Make sure that you don't have any syntax errors in your code.

I had a syntax error in my code, and after I fixed it, I was able to run add-migration.

You can do :

df['industry'] = 'yyy'

use kubeadm reset command. this will un-configure the kubernetes cluster.

This is how I fixed this issue on Windows 10:

My JDK is located in C:\Program Files\Java\jdk-11.0.2 and the problem I had was the space in Program Files. If I set JAVA_HOME using set JAVA_HOME="C:\Program Files\Java\jdk-11.0.2" then Maven had an issue with the double quotes:

C:\Users>set JAVA_HOME="C:\Program Files\Java\jdk-11.0.2"

C:\Users>echo %JAVA_HOME%
"C:\Program Files\Java\jdk-11.0.2"

C:\Users>mvn -version
Files\Java\jdk-11.0.2""=="" was unexpected at this time.

Referring to Program Files as PROGRA~1 didn't help either. The solution is using the PROGRAMFILES variable inside of JAVA_HOME:

C:\Users>echo %PROGRAMFILES%
C:\Program Files

C:\Program Files>set JAVA_HOME=%PROGRAMFILES%\Java\jdk-11.0.2

C:\Program Files>echo %JAVA_HOME%

Switching my conflicting dependencies from implementation to api does the trick. Here's a good article by mindorks explaining the difference.

https://medium.com/mindorks/implementation-vs-api-in-gradle-3-0-494c817a6fa

Edit:

Here's my dependency resolutions as well

 subprojects {
        project.configurations.all {
            resolutionStrategy.eachDependency { details ->
                if (details.requested.group == 'com.android.support'
                        && !details.requested.name.contains('multidex')) {
                    details.useVersion "28.0.0"
                }
                if (details.requested.group == 'com.google.android.gms'
                        && details.requested.name.contains('play-services-base')) {
                    details.useVersion "15.0.1"
                }

        }
    }

I had a similar problem:

module cv2 has no attribute "cv2.TrackerCSRT_create"

My Python version is 3.8.0 under Windows 10. The problem was the opencv version installation.

So I fixed this way (cmd prompt with administrator privileges):

1. Uninstalled opencv-python: pip uninstall opencv-python
2. Installed only opencv-contrib-python: pip install opencv-contrib-python

Allocate maximum memory to your docker machine from (docker preference -> advance )

Screenshot of advance settings:

This will set the maximum limit docker consume while running containers. Now run your image in new container with -m=4g flag for 4 gigs ram or more. e.g.

docker run -m=4g {imageID}

Remember to apply the ram limit increase changes. Restart the docker and double check that ram limit did increased. This can be one of the factor you not see the ram limit increase in docker containers.

Appart from setting maven source url to your gradle, I would suggest to add both design and appcompat libraries. Currently the latest version is 26.1.0

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

...

compile 'com.android.support:appcompat-v7:26.1.0'
compile 'com.android.support:design:26.1.0'

You could use ES6 Map

const colors = new Map([
  ['RED', 'red'],
  ['BLUE', 'blue'],
  ['GREEN', 'green']
]);

console.log(colors.get('RED'));

Deleted the package-lock.json file & then ran

npm install

The Kafka clients no longer require zookeeper but the Kafka servers do need it to operate.

You can get a list of topics with the new AdminClient API but the shell command that ship with Kafka have not yet been rewritten to use this new API.

The other way to use Kafka without Zookeeper is to use a SaaS Kafka-as-a-Service provider such as Confluent Cloud so you don’t see or operate the Kafka brokers (and the required backend Zookeeper ensemble).

For example on Confluent Cloud you would just use the following zookeeper free CLI command:

ccloud topic list

@everestial007 's solution worked for me. This is how I improved it for my use case, which is to have the columns of each different df with a different suffix so I can more easily differentiate between the dfs in the final merged dataframe.

from functools import reduce
import pandas as pd
dfs = [df1, df2, df3, df4]
suffixes = [f"_{i}" for i in range(len(dfs))]
# add suffixes to each df
dfs = [dfs[i].add_suffix(suffixes[i]) for i in range(len(dfs))]
# remove suffix from the merging column
dfs = [dfs[i].rename(columns={f"date{suffixes[i]}":"date"}) for i in range(len(dfs))]
# merge
dfs = reduce(lambda left,right: pd.merge(left,right,how='outer', on='date'), dfs)

For python2 users on MacOS (python@2 formula won't be found), as brew stopped support of python2 you need to use such command! But don't forget to unlink old python if it was pre-installed.

brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/86a44a0a552c673a05f11018459c9f5faae3becc/Formula/[email protected]

If you've done some mistake, simply brew uninstall python@2 old way, and try again.

In my case, I had to open the .csproj file and add the reference by hand, like this (Microsoft.Extensions.Identity.Stores.dll was missing):

<Reference Include="Microsoft.Extensions.Identity.Stores">

</Reference>

While the accepted answer solved the OP's original problem, most people finding this question through a Google search are likely having an entirely different problem which just happens to throw the same no suitable HttpMessageConverter found exception.

What happens under the covers is that MappingJackson2HttpMessageConverter swallows any exceptions that occur in its canRead() method, which is supposed to auto-detect whether the payload is suitable for json decoding. The exception is replaced by a simple boolean return that basically communicates sorry, I don't know how to decode this message to the higher level APIs (RestClient). Only after all other converters' canRead() methods return false, the no suitable HttpMessageConverter found exception is thrown by the higher-level API, totally obscuring the true problem.

For people who have not found the root cause (like you and me, but not the OP), the way to troubleshoot this problem is to place a debugger breakpoint on onMappingJackson2HttpMessageConverter.canRead(), then enable a general breakpoint on any exception, and hit Continue. The next exception is the true root cause.

My specific error happened to be that one of the beans referenced an interface that was missing the proper deserialization annotations.

UPDATE FROM THE FUTURE

This has proven to be such a recurring issue across so many of my projects, that I've developed a more proactive solution. Whenever I have a need to process JSON exclusively (no XML or other formats), I now replace my RestTemplate bean with an instance of the following:

public class JsonRestTemplate extends RestTemplate {

    public JsonRestTemplate(
            ClientHttpRequestFactory clientHttpRequestFactory) {
        super(clientHttpRequestFactory);

        // Force a sensible JSON mapper.
        // Customize as needed for your project's definition of "sensible":
        ObjectMapper objectMapper = new ObjectMapper()
                .registerModule(new Jdk8Module())
                .registerModule(new JavaTimeModule())
                .configure(
                        SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);

        List<HttpMessageConverter<?>> messageConverters = new ArrayList<>();
        MappingJackson2HttpMessageConverter jsonMessageConverter = new MappingJackson2HttpMessageConverter() {

            public boolean canRead(java.lang.Class<?> clazz,
                    org.springframework.http.MediaType mediaType) {
                return true;
            }    
            public boolean canRead(java.lang.reflect.Type type,
                    java.lang.Class<?> contextClass,
                    org.springframework.http.MediaType mediaType) {
                return true;
            }
            protected boolean canRead(
                    org.springframework.http.MediaType mediaType) {
                return true;
            }
        };

        jsonMessageConverter.setObjectMapper(objectMapper);
        messageConverters.add(jsonMessageConverter);
        super.setMessageConverters(messageConverters);

    }
}

This customization makes the RestClient incapable of understanding anything other than JSON. The upside is that any error messages that may occur will be much more explicit about what's wrong.

Select is used for projecting some or all fields of a dataframe. It won't give you an value as an output but a new dataframe. Its a transformation.

Since Django 2.0 the ForeignKey field requires two positional arguments:

1. the model to map to
2. the on_delete argument

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

Here are some methods can used in on_delete

1. CASCADE

Cascade deletes. Django emulates the behavior of the SQL constraint ON DELETE CASCADE and also deletes the object containing the ForeignKey

2. PROTECT

Prevent deletion of the referenced object by raising ProtectedError, a subclass of django.db.IntegrityError.

3. DO_NOTHING

Take no action. If your database backend enforces referential integrity, this will cause an IntegrityError unless you manually add an SQL ON DELETE constraint to the database field.

you can find more about on_delete by reading the documentation.

Hope you are having app.module.ts. In your app.module.ts add below line-

 exports: [myComponentComponent],

Like this:

import { NgModule, Renderer } from '@angular/core';
import { HeaderComponent } from './headerComponent/header.component';
import { HeaderMainComponent } from './component';
import { RouterModule } from '@angular/router';

@NgModule({
    declarations: [
        HeaderMainComponent,
        HeaderComponent
    ],
    imports: [
        RouterModule,
    ],
    providers: [],
    bootstrap: [HeaderMainComponent],
    exports: [HeaderComponent],
})
export class HeaderModule { }

It's complicated.

First of all, in this code

const p = new Promise((resolve) => {
    resolve(4);
});

the type of p is inferred as Promise<{}>. There is open issue about this on typescript github, so arguably this is a bug, because obviously (for a human), p should be Promise<number>.

Then, Promise<{}> is compatible with Promise<number>, because basically the only property a promise has is then method, and then is compatible in these two promise types in accordance with typescript rules for function types compatibility. That's why there is no error in whatever1.

But the purpose of async is to pretend that you are dealing with actual values, not promises, and then you get the error in whatever2 because {} is obvioulsy not compatible with number.

So the async behavior is the same, but currently some workaround is necessary to make typescript compile it. You could simply provide explicit generic argument when creating a promise like this:

const whatever2 = async (): Promise<number> => {
    return new Promise<number>((resolve) => {
        resolve(4);
    });
};

You should use Linking.

Example from the docs:

class OpenURLButton extends React.Component {
  static propTypes = { url: React.PropTypes.string };
  handleClick = () => {
    Linking.canOpenURL(this.props.url).then(supported => {
      if (supported) {
        Linking.openURL(this.props.url);
      } else {
        console.log("Don't know how to open URI: " + this.props.url);
      }
    });
  };
  render() {
    return (
      <TouchableOpacity onPress={this.handleClick}>
        {" "}
        <View style={styles.button}>
          {" "}<Text style={styles.text}>Open {this.props.url}</Text>{" "}
        </View>
        {" "}
      </TouchableOpacity>
    );
  }
}

Here's an example you can try on Expo Snack:

import React, { Component } from 'react';
import { View, StyleSheet, Button, Linking } from 'react-native';
import { Constants } from 'expo';

export default class App extends Component {
  render() {
    return (
      <View style={styles.container}>
       <Button title="Click me" onPress={ ()=>{ Linking.openURL('https://google.com')}} />
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
    paddingTop: Constants.statusBarHeight,
    backgroundColor: '#ecf0f1',
  },
});

Okay...So here is what solved my problem...

in App Delegate File:

#import "AppDelegate.h"
#import "DarkSkyAPI.h"
//#import "Credentials.h"

I had imported Credentials.h already in the DarkSkyAPI.m file in my project. Commenting out the extra import made the error go away!

Some things to mention and maybe help anyone in the future. @umairqureshi_6's answer did help me along the process, but did not solve it. He led to where I was able to dig out the info. I kept seeing AppDelegate and DarkSkyAPI files showing up in the error log and the information it was pulling from Credentials file was causing the error. I knew it had to be in one of these 3 files, so I immediately checked imports, because I remembered hearing that the .h carries all the imports from its .m file. Boom!

ECMAScript 6 introduced the let statement. You can use it in a for statement.

var ids:string = [];

for(let result of this.results){
   ids.push(result.Id);
}

I had win10 SDK and I only had to do retarget and then I stopped getting this error. The idea was that the project needs to upgrade its target Windows SDK.

It's not supported just yet... If you want to use it you will have to install Babel.

your first try is using declarative pipelines, and the second working one is using scripted pipelines. you need to enclose steps in a steps declaration, and you can't use if as a top-level step in declarative, so you need to wrap it in a script step. here's a working declarative version:

pipeline {
    agent any

    stages {
        stage('test') {
            steps {
                sh 'echo hello'
            }
        }
        stage('test1') {
            steps {
                sh 'echo $TEST'
            }
        }
        stage('test3') {
            steps {
                script {
                    if (env.BRANCH_NAME == 'master') {
                        echo 'I only execute on the master branch'
                    } else {
                        echo 'I execute elsewhere'
                    }
                }
            }
        }
    }
}

you can simplify this and potentially avoid the if statement (as long as you don't need the else) by using "when". See "when directive" at https://jenkins.io/doc/book/pipeline/syntax/. you can also validate jenkinsfiles using the jenkins rest api. it's super sweet. have fun with declarative pipelines in jenkins!

I got the same error on my vscode where I had a library installed and the code working when running from the terminal, but for some reason, the vscode pylint was not able to pick the installed package returning the infamous error:

Unable to import 'someLibrary.someModule' pylint(import-error)

The problem might arise due to the multiple Python installations. Basically you have installed a library/package on one, and vscode pylint is installed and running from another installation. For example, on macOS and many Linux distros, there are by default Python2 installed and when you install Python3 this might cause confusion. Also on windows the Chocolatey package manager might cause some mess and you end up with multiple Python installations. To figure it out if you are on a *nix machine (i.e., macOS, GNU/Linux, BSD...), use the which command, and if you are on Windows, use the where command to find the installed Python interpreters. For example, on *nix machines:

which python3

and on Windows

where python

then you may want to uninstall the ones you don't want. and the one you want to use check if the package causing above issue is installed by

python -c "import someLibrary"

if you get an error then you should install it by for example pip:

pip install someLibrary

then on vscode press ??P if you are on a mac and CtrlShiftP on other operating systems. Then type-select the >python: Select Interpreter option and select the one you know have the library installed. At this moment vscode might asks you to install pyling again, which you just go on with.

I encountered this issue when working on a Java Project in Debian 10.

Each time I start the appliction it throws the error in the log file:

java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException

Here's how I solved it:

The issue is often caused when JAXB library (Java Architecture for XML Binding) is missing in the classpath. JAXB is included in Java SE 10 or older, but it is removed from Java SE from Java 11 or newer –moved to Java EE under Jakarta EE project.

So, I checked my Java version using:

java --version

And it gave me this output

openjdk 11.0.8 2020-07-14
OpenJDK Runtime Environment (build 11.0.8+10-post-Debian-1deb10u1)
OpenJDK 64-Bit Server VM (build 11.0.8+10-post-Debian-1deb10u1, mixed mode, sharing)

So I was encountering the JAXBException error because I was using Java 11, which does not have the JAXB library (Java Architecture for XML Binding) is missing in the classpath. JAXB is included in it.

To fix the issue I had to add the JAXB API library to the lib (/opt/tomcat/lib) directory of my tomcat installation:

sudo wget https://repo1.maven.org/maven2/javax/xml/bind/jaxb-api/2.4.0-b180830.0359/jaxb-api-2.4.0-b180830.0359.jar

Then I renamed it from jaxb-api-2.4.0-b180830.0359.jar to jaxb-api.jar:

sudo mv jaxb-api-2.4.0-b180830.0359.jar jaxb-api.jar

Note: Ensure that you change the permission allow tomcat access the file and also change the ownership to tomcat:

sudo chown -R tomcat:tomcat /opt/tomcat
sudo chmod -R 777 /opt/tomcat/

And then I restarted the tomcat server:

sudo systemctl restart tomcat

Resources: [Solved] java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException

That's all.

I hope this helps

None of the answers worked until I removed the HasNoKey() method from the entity. Dont forget to remove this from your data context or the [Key] attribute will not fix anything.

I think in your Angular-2 version directives are not supported in Component decorator, hence you have to register directive same as other component in @NgModule and then import in component as below and also remove directives: [ChildComponent] from decorator.

import {myDirective} from './myDirective';

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'

Then it will send password to your email and you will be able to sign.

Or, for an unknown number of child columns, use flexbox and the cols will fill height. See the d-flex flex-column on the row, and h-100 on the child cols.

Very easy solution (2 min to config) is to use local-ssl-proxy package from npm

The usage is straight pretty forward:
1. Install the package: npm install -g local-ssl-proxy
2. While running your local-server mask it with the local-ssl-proxy --source 9001 --target 9000

P.S: Replace --target 9000 with the -- "number of your port" and --source 9001 with --source "number of your port +1"

When you use a blade echo {{ $data }} it will automatically escape the output. It can only escape strings. In your data $data->ac is an array and $data is an object, neither of which can be echoed as is. You need to be more specific of how the data should be outputted. What exactly that looks like entirely depends on what you're trying to accomplish. For example to display the link you would need to do {{ $data->ac[0][0]['url'] }} (not sure why you have two nested arrays but I'm just following your data structure).

@foreach($data->ac['0'] as $link)
    <a href="{{ $link['url'] }}">This is a link</a>
@endforeach

1. Install Anaconda
2. Run Anaconda command prompt
3. write "activate tensorflow" for windows
4. pip install tensorflow
5. pip install jupyter notebook
6. jupyter notebook.

Only this solution worked for me. Tried 7 8 solutions. Using Windows platform.

spring.jpa.hibernate.ddl-auto = update

change update to create, and run it

after run safely again change create to update so again all tables will not create and you can use your previous data

const Root = ({ session }) => {
  const isLoggedIn = session && session.getCurrentUser
  return (
    <Router>
      {!isLoggedIn ? (
        <Switch>

As the error message states, the method used to get the F score is from the "Classification" part of sklearn - thus the talking about "labels".

Do you have a regression problem? Sklearn provides a "F score" method for regression under the "feature selection" group: http://scikit-learn.org/stable/modules/generated/sklearn.feature_selection.f_regression.html

In case you do have a classification problem, @Shovalt's answer seems correct to me.

var nvc = new List<KeyValuePair<string, string>>();
nvc.Add(new KeyValuePair<string, string>("Input1", "TEST2"));
nvc.Add(new KeyValuePair<string, string>("Input2", "TEST2"));
var client = new HttpClient();
var req = new HttpRequestMessage(HttpMethod.Post, url) { Content = new FormUrlEncodedContent(nvc) };
var res = await client.SendAsync(req);

Or

var dict = new Dictionary<string, string>();
dict.Add("Input1", "TEST2");
dict.Add("Input2", "TEST2");
var client = new HttpClient();
var req = new HttpRequestMessage(HttpMethod.Post, url) { Content = new FormUrlEncodedContent(dict) };
var res = await client.SendAsync(req);

You may be looking for auto-fill:

grid-template-columns: repeat(auto-fill, 186px);

Demo: http://codepen.io/alanbuchanan/pen/wJRMox

To use up the available space more efficiently, you could use minmax, and pass in auto as the second argument:

grid-template-columns: repeat(auto-fill, minmax(186px, auto));

Demo: http://codepen.io/alanbuchanan/pen/jBXWLR

If you don't want the empty columns, you could use auto-fit instead of auto-fill.

curl's --data will by default send Content-Type: application/x-www-form-urlencoded in the request header. However, when using Postman's raw body mode, Postman sends Content-Type: text/plain in the request header.

So to achieve the same thing as Postman, specify -H "Content-Type: text/plain" for curl:

curl -X POST -H "Content-Type: text/plain" --data "this is raw data" http://78.41.xx.xx:7778/

Note that if you want to watch the full request sent by Postman, you can enable debugging for packed app. Check this link for all instructions. Then you can inspect the app (right-click in Postman) and view all requests sent from Postman in the network tab :

For those who are experiencing same problem after controlling there is no suspicious java process which allocate the port, there is no red square on eclipse to terminate any process and also there is no change even you try different port for your spring boot application.

might sound stupid but; restarting eclipse works. :)

I had reinstalled nvidia driver: run these commands in root mode:

1. systemctl isolate multi-user.target

2. modprobe -r nvidia-drm

3. Reinstall Nvidia driver: chmod +x NVIDIA-Linux-x86_64–410.57.run

4. systemctl start graphical.target

and finally check nvidia-smi

How to unload kernel module 'nvidia-drm'?

If you don't want to use a FormData object (e.g. your API takes specific content-type signatures and multipart/formdata isn't one of them) then you can do this instead:

uploadFile: function (event) {
    const file = event.target.files[0]
    axios.post('upload_file', file, {
        headers: {
          'Content-Type': file.type
        }
    })
}

<div *ngIf="show; else elseBlock">Text to show</div>
<ng-template #elseBlock>Alternate text while primary text is hidden</ng-template>

I am working with a AWS DeepAMI P2 instance and suddenly I found that Nvidia-driver command doesn't working and GPU is not found torch or tensorflow library. Then I have resolved the problem in the following way,

Run nvcc --version if it doesn't work

Then run the following

apt install nvidia-cuda-toolkit

Hopefully that will solve the problem.

pixels = np.array(pixels) in this line you reassign pixels. So, it may not a list anyhow. Though pixels is not a list it has no attributes append. Does it make sense?

The commands for what specific codes to run are listed inside your package.json file under scripts. Here is an example of mine:

"scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint"
  },

If you are looking to run your site locally, you can test it with

npm serve

If you are looking to prep your site for production, you would use

npm build

This command will generate a dist folder that has a compressed version of your site.

Here another cleaner solution by using docker-compose and a js script.

This example assumes that both files (docker-compose.yml and mongo-init.js) lay in the same folder.

docker-compose.yml

version: '3.7'

services:
    mongodb:
        image: mongo:latest
        container_name: mongodb
        restart: always
        environment:
            MONGO_INITDB_ROOT_USERNAME: <admin-user>
            MONGO_INITDB_ROOT_PASSWORD: <admin-password>
            MONGO_INITDB_DATABASE: <database to create>
        ports:
            - 27017:27017
        volumes:
            - ./mongo-init.js:/docker-entrypoint-initdb.d/mongo-init.js:ro

mongo-init.js

db.createUser(
        {
            user: "<user for database which shall be created>",
            pwd: "<password of user>",
            roles: [
                {
                    role: "readWrite",
                    db: "<database to create>"
                }
            ]
        }
);

Then simply start the service by running the following docker-compose command

docker-compose up --build -d mongodb 

Note: The code in the docker-entrypoint-init.d folder is only executed if the database has never been initialized before.

For me was easier to create a new test project that works perfectly fine with Visual Studio 2017... and just copy the test files, add references, and NuGet packages as required.

I faced a similar issue, and I solved that after doing the following:

1. check your jupyter configuration file: this is described here in details; https://testnb.readthedocs.io/en/stable/examples/Notebook/Configuring%20the%20Notebook%20and%20Server.html

-- you will simply need from the link above to learn how to make jupyter server listens to your local machin IP -- you will need to know your local machin IP (i use "ifconfig -a" on ubuntu to find that out) - please check for centos6

after you finish setting your configuration, you can run jupyter notebook at your local IP: jupyter notebook --ip=* --no-browser

please replace * with your IP address for example: jupyter notebook --ip=192.168.x.x --no-browser

you can now access your jupyter server from any device connected to the router using this ip:port (the port is usually 8888, so for my case for instance I used "192.168.x.x:8888" to access my server from other devices)

now if you want to access this server from public IP, you will have to:

1. find your public IP (simply type on google what is my IP)
2. use this IP address instead of your local IP to access the server from any device not connected to the same router kindly note: if your linux server runs on Virtual machine, you will need to set your router to allow accessing your VB from public IPs, settings depends on the router type. otherwise, you should be able to access the server using the public IP and the port set for it from any device not connected to your router, or using your local IP and the port set from any device connected to the same router!

Customizing CORS for Angular 5 and Spring Security (Cookie base solution)

On the Angular side required adding option flag withCredentials: true for Cookie transport:

constructor(public http: HttpClient) {
}

public get(url: string = ''): Observable<any> {
    return this.http.get(url, { withCredentials: true });
}

On Java server-side required adding CorsConfigurationSource for configuration CORS policy:

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        // This Origin header you can see that in Network tab
        configuration.setAllowedOrigins(Arrays.asList("http:/url_1", "http:/url_2")); 
        configuration.setAllowedMethods(Arrays.asList("GET","POST"));
        configuration.setAllowedHeaders(Arrays.asList("content-type"));
        configuration.setAllowCredentials(true);
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.cors().and()...
    }
}

Method configure(HttpSecurity http) by default will use corsConfigurationSource for http.cors()

I would suggest not to use seaborn pointplot for plotting. This makes things unnecessarily complicated.
Instead use matplotlib plot_date. This allows to set labels to the plots and have them automatically put into a legend with ax.legend().

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

date = pd.date_range("2017-03", freq="M", periods=15)
count = np.random.rand(15,4)
df1 = pd.DataFrame({"date":date, "count" : count[:,0]})
df2 = pd.DataFrame({"date":date, "count" : count[:,1]+0.7})
df3 = pd.DataFrame({"date":date, "count" : count[:,2]+2})

f, ax = plt.subplots(1, 1)
x_col='date'
y_col = 'count'

ax.plot_date(df1.date, df1["count"], color="blue", label="A", linestyle="-")
ax.plot_date(df2.date, df2["count"], color="red", label="B", linestyle="-")
ax.plot_date(df3.date, df3["count"], color="green", label="C", linestyle="-")

ax.legend()

plt.gcf().autofmt_xdate()
plt.show()

sns.pointplot(ax=ax,x=x_col,y=y_col,data=df1,color='blue')
sns.pointplot(ax=ax,x=x_col,y=y_col,data=df2,color='green')
sns.pointplot(ax=ax,x=x_col,y=y_col,data=df3,color='red')

ax.legend(handles=ax.lines[::len(df1)+1], labels=["A","B","C"])

ax.set_xticklabels([t.get_text().split("T")[0] for t in ax.get_xticklabels()])
plt.gcf().autofmt_xdate()

plt.show()

@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 was in a position where I had 6 identical arrays and I needed to pick the right one depending on another variable and then assign values to it. In the case shown here $comp_cat was 'a' so I needed to pick my 'a' array ( I also of course had 'b' to 'f' arrays)

Note that the values for the position of the variable in the array go after the closing brace.

${'comp_cat_'.$comp_cat.'_arr'}[1][0] = "FRED BLOGGS";

${'comp_cat_'.$comp_cat.'_arr'}[1][1] = $file_tidy;

echo 'First array value is '.$comp_cat_a_arr[1][0].' and the second value is .$comp_cat_a_arr[1][1];

Use includeHTML (smallest js-lib: ~150 lines)

Loading HTML parts via HTML tag (pure js)
Supported load: async/sync, any deep recursive includes

Supported protocols: http://, https://, file:///
Supported browsers: IE 9+, FF, Chrome (and may be other)

USAGE:

1.Insert includeHTML into head section (or before body close tag) in HTML file:

<script src="js/includeHTML.js"></script>

2.Anywhere use includeHTML as HTML tag:

<div data-src="header.html"></div>

This line

 except Vehicle.vehicledevice.device.DoesNotExist

means look for device instance for DoesNotExist exception, but there's none, because it's on class level, you want something like

 except Device.DoesNotExist

http://msdn.microsoft.com/en-us/library/system.type.gettype.aspx

Console.WriteLine("typeField is a {0}", typeField.GetType());

which would give you something like

typeField is a String

typeField is a DateTime

or

You may also use the handy replace_na function: https://tidyr.tidyverse.org/reference/replace_na.html

this is what I do, python3.3. I was processing huge lists of sites, so failing on the timeout was vital for the job to run through the entire list.

command = "phantomjs --ignore-ssl-errors=true "+<your js file for phantom>
process = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE)

# make sure phantomjs has time to download/process the page
# but if we get nothing after 30 sec, just move on
try:
    output, errors = process.communicate(timeout=30)
except Exception as e:
    print("\t\tException: %s" % e)
    process.kill()

# output will be weird, decode to utf-8 to save heartache
phantom_output = ''
for out_line in output.splitlines():
    phantom_output += out_line.decode('utf-8')

Simple method to get the records count:

df.count()[0]

This is C++11 code. In C++11, the && token can be used to mean an "rvalue reference".

Add services.AddSingleton(); in your ConfigureServices method of Startup.cs file of your project.

public void ConfigureServices(IServiceCollection services)
    {
        services.AddRazorPages();
        // To register interface with its concrite type
        services.AddSingleton<IEmployee, EmployeesMockup>();
    }

From the same folder, you can do:

import test

Look at

For Each c as DataColumn in dt.Columns
  '... = c.ColumnName

or:

dt.GetDataTableSchema(...)

Well, for just getting the filename of your batch the easiest way would be to just use %~n0.

@echo %~n0

will output the name (without the extension) of the currently running batch file (unless executed in a subroutine called by call). The complete list of such “special” substitutions for path names can be found with help for, at the very end of the help:

In addition, substitution of FOR variable references has been enhanced. You can now use the following optional syntax:

%~I         - expands %I removing any surrounding quotes (")
%~fI        - expands %I to a fully qualified path name
%~dI        - expands %I to a drive letter only
%~pI        - expands %I to a path only
%~nI        - expands %I to a file name only
%~xI        - expands %I to a file extension only
%~sI        - expanded path contains short names only
%~aI        - expands %I to file attributes of file
%~tI        - expands %I to date/time of file
%~zI        - expands %I to size of file
%~$PATH:I   - searches the directories listed in the PATH
               environment variable and expands %I to the
               fully qualified name of the first one found.
               If the environment variable name is not
               defined or the file is not found by the
               search, then this modifier expands to the
               empty string

The modifiers can be combined to get compound results:

%~dpI       - expands %I to a drive letter and path only
%~nxI       - expands %I to a file name and extension only
%~fsI       - expands %I to a full path name with short names only

To precisely answer your question, however: Substrings are done using the :~start,length notation:

%var:~10,5%

will extract 5 characters from position 10 in the environment variable %var%.

NOTE: The index of the strings is zero based, so the first character is at position 0, the second at 1, etc.

To get substrings of argument variables such as %0, %1, etc. you have to assign them to a normal environment variable using set first:

:: Does not work:
@echo %1:~10,5

:: Assign argument to local variable first:
set var=%1
@echo %var:~10,5%

The syntax is even more powerful:

• %var:~-7% extracts the last 7 characters from %var%
• %var:~0,-4% would extract all characters except the last four which would also rid you of the file extension (assuming three characters after the period [.]).

See help set for details on that syntax.

Using lxml:

from lxml import etree

# create XML 
root = etree.Element('root')
root.append(etree.Element('child'))
# another child with text
child = etree.Element('child')
child.text = 'some text'
root.append(child)

# pretty string
s = etree.tostring(root, pretty_print=True)
print s

Output:

<root>
  <child/>
  <child>some text</child>
</root>

See the tutorial for more information.

You need to escape those but don't just replace it by %2F manually. You can use URLEncoder for this.

Eg URLEncoder.encode(url, "UTF-8")

Then you can say

yourUrl = "www.musicExplained/index.cfm/artist/" + URLEncoder.encode(VariableName, "UTF-8")

You can use alexw's solution with the Artisan. Run following commands in the command line.

php artisan tinker
DB::connection()->getPdo();

If connection is OK, you should see

CONNECTION_STATUS: "Connection OK; waiting to send.",

near the end of the response.

I used some of the answers given here but just a heads up that

Get-Content -Path Yourfile.log -Tail 30 -Wait 

will chew up memory after awhile. A colleague left such a "tail" up over the last day and it went up to 800 MB. I don't know if Unix tail behaves the same way (but I doubt it). So it's fine to use for short term applications, but be careful with it.

All OS comes with a default version of python and it resides in /usr/bin. All scripts that come with the OS (e.g. yum) point this version of python residing in /usr/bin. When you want to install a new version of python you do not want to break the existing scripts which may not work with new version of python.

The right way of doing this is to install the python as an alternate version.

e.g.
wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2 
tar xf Python-2.7.3.tar.bz2
cd Python-2.7.3
./configure --prefix=/usr/local/
make && make altinstall

Now by doing this the existing scripts like yum still work with /usr/bin/python. and your default python version would be the one installed in /usr/local/bin. i.e. when you type python you would get 2.7.3

This happens because. $PATH variable has /usr/local/bin before usr/bin.

/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

If python2.7 still does not take effect as the default python version you would need to do

export PATH="/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin"

I had the same problem. Perhaps, the problem is that you have compiled and executed the class with different Java versions.

Make sure the version of the compiler is the same as the command "java":

javac -version

java -version

In Linux, use

sudo update-alternatives --config java

to change the version of Java.

Bootstrap 4 CSS-only

None of the CSS only answers work entirely. Either the dropdown menu stays open after click, or there is a gap that makes the dropdown menu hide before you can reach the menu links to click.

Here's the simple CSS only solution:

.navbar-nav li:hover .dropdown-menu {
    display: block;
}

Remove data-toggle=dropdown from the HTML markup to prevent the dropdown staying open in click. Use mt-0 (margin-top:0) to eliminate the gap above the menu, and make it possible to hover the menu items.

Demo https://www.codeply.com/go/awyU7VTIJf

Complete Code:

   .navbar-nav li:hover .dropdown-menu {
        display: block;
    } 

   <nav class="navbar navbar-expand-lg navbar-light bg-light">
      ..
      <div class="collapse navbar-collapse" id="navbarSupportedContent">
        <ul class="navbar-nav mr-auto">
          <li class="nav-item dropdown">
            <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown">
              Dropdown
            </a>
            <div class="dropdown-menu mt-0" aria-labelledby="navbarDropdown">
              <a class="dropdown-item" href="#">Action</a>
              <a class="dropdown-item" href="#">Another action</a>
              <div class="dropdown-divider"></div>
              <a class="dropdown-item" href="#">Something else here</a>
            </div>
          </li>
        </ul>
      </div>
    </nav>   

Open the hosts file located at : **C:\windows\system32\drivers\etc**.

Hosts file is for what?

Add the following at end of this file :

Example:

if you're doing a lot of this kind of thing you should consider using numpy.

In [56]: import random, numpy

In [57]: lst = numpy.array([random.uniform(0, 5) for _ in range(1000)]) # example list

In [58]: a, b = 1, 3

In [59]: numpy.flatnonzero((lst > a) & (lst < b))[:10]
Out[59]: array([ 0, 12, 13, 15, 18, 19, 23, 24, 26, 29])

In response to Seanny123's question, I used this timing code:

import numpy, timeit, random

a, b = 1, 3

lst = numpy.array([random.uniform(0, 5) for _ in range(1000)])

def numpy_way():
    numpy.flatnonzero((lst > 1) & (lst < 3))[:10]

def list_comprehension():
    [e for e in lst if 1 < e < 3][:10]

print timeit.timeit(numpy_way)
print timeit.timeit(list_comprehension)

The numpy version is over 60 times faster.

Rather than using javscript/jquery the easiest way I found is:

<iframe style="min-height:98vh" src="http://yourdomain.com" width="100%"></iframe>

Here 1vh = 1% of Browser window height. So the theoretical value of height to be set is 100vh but practically 98vh did the magic.

As the previous answers saids, try to move the state to a top component and modify the state through callbacks passed to it's children.

In case that you really need to access to a child state that is declared as a functional component (hooks) you can declare a ref in the parent component, then pass it as a ref attribute to the child but you need to use React.forwardRef and then the hook useImperativeHandle to declare a function you can call in the parent component.

Take a look at the following example:

const Parent = () => {
    const myRef = useRef();
    return <Child ref={myRef} />;
}

const Child = React.forwardRef((props, ref) => {
    const [myState, setMyState] = useState('This is my state!');
    useImperativeHandle(ref, () => ({getMyState: () => {return myState}}), [myState]);
})

Then you should be able to get myState in the Parent component by calling: myRef.current.getMyState();

As explained above by @kris, depending on the region configurations of MS Excel it won't interpret the comma as the separator character. In my case I had to change it to semi-colon

Another solution:

for /f "tokens=2 delims==" %%I in ('wmic os get localdatetime /format:list') do set datetime=%%I

It will give you (independent of locale settings!):

  20130802203023.304000+120
( YYYYMMDDhhmmss.<milliseconds><always 000>+/-<minutes difference to UTC>  )

From here, it is easy:

set datetime=%datetime:~0,8%-%datetime:~8,6%
20130802-203023

For Logan's request for the same outputformat for the "date-time modified" of a file:

for %%F in (test.txt) do set file=%%~fF
for /f "tokens=2 delims==" %%I in ('wmic datafile where name^="%file:\=\\%" get lastmodified /format:list') do set datetime=%%I
echo %datetime%

It is a bit more complicated, because it works only with full paths, wmic expects the backslashes to be doubled and the = has to be escaped (the first one. The second one is protected by surrounding quotes).

Simple Add this Code

        var status = "play"; // Declare global variable

        if (status == 'pause') {
            status='play';                
        } else {
            status = 'pause';     
        }
        $("#audio").trigger(status);    

The answer of Mintir4 is fine, I would also do the following to load the file.

FileInputStream fis = myContext.openFileInput(fn);
BufferedReader r = new BufferedReader(new InputStreamReader(fis));
String s = "";

while ((s = r.readLine()) != null) {
    txt += s;
}

r.close();

For me, using expo, I just had to restart expo. ctrl + c and yarn start or expo start and the run on ios simulator or your device, whichever you're testing with.

You can use twiny to create 2 x-axis scales. For Example:

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax1 = fig.add_subplot(111)
ax2 = ax1.twiny()

a = np.cos(2*np.pi*np.linspace(0, 1, 60.))

ax1.plot(range(60), a)
ax2.plot(range(100), np.ones(100)) # Create a dummy plot
ax2.cla()
plt.show()

It says

The keypress event is sent to an element when the browser registers keyboard input. This is similar to the keydown event, except that modifier and non-printing keys such as Shift, Esc, and delete trigger keydown events but not keypress events. Other differences between the two events may arise depending on platform and browser.

That means you can not use keypress in case of arrows.

setting the overflow should take care of it, but you need to set the height of Content also. If the height attribute is not set, the div will grow vertically as tall as it needs to, and scrollbars wont be needed.

If you can't REINDEX a workaround is to use aliases. From the official documentation:

APIs in elasticsearch accept an index name when working against a specific index, and several indices when applicable. The index aliases API allow to alias an index with a name, with all APIs automatically converting the alias name to the actual index name. An alias can also be mapped to more than one index, and when specifying it, the alias will automatically expand to the aliases indices. An alias can also be associated with a filter that will automatically be applied when searching, and routing values. An alias cannot have the same name as an index.

Be aware that this solution does not work if you're using More Like This feature. https://github.com/elastic/elasticsearch/issues/16560

I had this issue after installing dotnetframework4.5.
Open path below:

In this path find file cvtres.exe and rename it to cvtres1.exe then compile your project again.

I got the same error and ended up using a pre-built distribution of numpy available in SourceForge (similarly, a distribution of matplotlib can be obtained).

After trying many methods here, I decided to use github.com/Pomax/react-onclickoutside because of how complete it is.

I installed the module via npm and imported it into my component:

import onClickOutside from 'react-onclickoutside'

Then, in my component class I defined the handleClickOutside method:

handleClickOutside = () => {
  console.log('onClickOutside() method called')
}

And when exporting my component I wrapped it in onClickOutside():

export default onClickOutside(NameOfComponent)

That's it.

For me the solution was just replace unsigned with index

This is the full code:

        $table->increments('id');
        $table->integer('cid')->index();
        $table->longText('name');
    });


    Schema::create('champions_stats',function (Blueprint $table){
        $table->engine = 'InnoDB';
        $table->increments('id');
        $table->integer('championd_id')->index();
        $table->foreign('championd_id', 'ch_id')->references('cid')->on('champions_overview');
    });

Best the algorithm is based on the recursive power definition of a^b.

long pow (long a, int b)
{
    if ( b == 0)        return 1;
    if ( b == 1)        return a;
    if (isEven( b ))    return     pow ( a * a, b/2); //even a=(a^2)^b/2
    else                return a * pow ( a * a, b/2); //odd  a=a*(a^2)^b/2

}

Running time of the operation is O(logb). Reference:More information

I got the same error message before. in my case, it was caused by type casting. check if siteID is a string, if it is you must add simple quotes.

Neo4j cannot delete nodes that have a relation. You have to delete the relations before you can delete the nodes.

But, it is simple way to delete "ALL" nodes and "ALL" relationships with a simple chyper. This is the code:

MATCH (n) DETACH DELETE n

--> DETACH DELETE will remove all of the nodes and relations by Match

This is what I use (typically for html table email reports)

declare @time int, @hms varchar(20)
set @time = 12345
set @hms = cast(cast((@Time)/3600 as int) as varchar(3)) 
  +':'+ right('0'+ cast(cast(((@Time)%3600)/60 as int) as varchar(2)),2) 
  +':'+ right('0'+ cast(((@Time)%3600)%60 as varchar(2)),2) +' (hh:mm:ss)'
select @hms

This is the easy way to do it. If you're going backwards, just add $("#Prefix").val($("#Prefix").val()); after you set the focus

This is the more proper (cleaner) way:

function SetCaretAtEnd(elem) {
        var elemLen = elem.value.length;
        // For IE Only
        if (document.selection) {
            // Set focus
            elem.focus();
            // Use IE Ranges
            var oSel = document.selection.createRange();
            // Reset position to 0 & then set at end
            oSel.moveStart('character', -elemLen);
            oSel.moveStart('character', elemLen);
            oSel.moveEnd('character', 0);
            oSel.select();
        }
        else if (elem.selectionStart || elem.selectionStart == '0') {
            // Firefox/Chrome
            elem.selectionStart = elemLen;
            elem.selectionEnd = elemLen;
            elem.focus();
        } // if
    } // SetCaretAtEnd()

This is a few months late but I thought I'd provide my solution based on this here tutorial. The gist of it is that it's a lot easier to manage once you change the way you approach forms.

First, use ReactiveFormsModule instead of or in addition to the normal FormsModule. With reactive forms you create your forms in your components/services and then plug them into your page instead of your page generating the form itself. It's a bit more code but it's a lot more testable, a lot more flexible, and as far as I can tell the best way to make a lot of non-trivial forms.

The end result will look a little like this, conceptually:

• You have one base FormGroup with whatever FormControl instances you need for the entirety of the form. For example, as in the tutorial I linked to, lets say you want a form where a user can input their name once and then any number of addresses. All of the one-time field inputs would be in this base form group.

• Inside that FormGroup instance there will be one or more FormArray instances. A FormArray is basically a way to group multiple controls together and iterate over them. You can also put multiple FormGroup instances in your array and use those as essentially "mini-forms" nested within your larger form.

• By nesting multiple FormGroup and/or FormControl instances within a dynamic FormArray, you can control validity and manage the form as one, big, reactive piece made up of several dynamic parts. For example, if you want to check if every single input is valid before allowing the user to submit, the validity of one sub-form will "bubble up" to the top-level form and the entire form becomes invalid, making it easy to manage dynamic inputs.

• As a FormArray is, essentially, a wrapper around an array interface but for form pieces, you can push, pop, insert, and remove controls at any time without recreating the form or doing complex interactions.

In case the tutorial I linked to goes down, here some sample code you can implement yourself (my examples use TypeScript) that illustrate the basic ideas:

Base Component code:

import { Component, Input, OnInit } from '@angular/core';
import { FormArray, FormBuilder, FormGroup, Validators } from '@angular/forms';

@Component({
  selector: 'my-form-component',
  templateUrl: './my-form.component.html'
})
export class MyFormComponent implements OnInit {
    @Input() inputArray: ArrayType[];
    myForm: FormGroup;

    constructor(private fb: FormBuilder) {}
    ngOnInit(): void {
        let newForm = this.fb.group({
            appearsOnce: ['InitialValue', [Validators.required, Validators.maxLength(25)]],
            formArray: this.fb.array([])
        });

        const arrayControl = <FormArray>newForm.controls['formArray'];
        this.inputArray.forEach(item => {
            let newGroup = this.fb.group({
                itemPropertyOne: ['InitialValue', [Validators.required]],
                itemPropertyTwo: ['InitialValue', [Validators.minLength(5), Validators.maxLength(20)]]
            });
            arrayControl.push(newGroup);
        });

        this.myForm = newForm;
    }
    addInput(): void {
        const arrayControl = <FormArray>this.myForm.controls['formArray'];
        let newGroup = this.fb.group({

            /* Fill this in identically to the one in ngOnInit */

        });
        arrayControl.push(newGroup);
    }
    delInput(index: number): void {
        const arrayControl = <FormArray>this.myForm.controls['formArray'];
        arrayControl.removeAt(index);
    }
    onSubmit(): void {
        console.log(this.myForm.value);
        // Your form value is outputted as a JavaScript object.
        // Parse it as JSON or take the values necessary to use as you like
    }
}

Sub-Component Code: (one for each new input field, to keep things clean)

import { Component, Input } from '@angular/core';
import { FormGroup } from '@angular/forms';

@Component({
    selector: 'my-form-sub-component',
    templateUrl: './my-form-sub-component.html'
})
export class MyFormSubComponent {
    @Input() myForm: FormGroup; // This component is passed a FormGroup from the base component template
}

Base Component HTML

<form [formGroup]="myForm" (ngSubmit)="onSubmit()" novalidate>
    <label>Appears Once:</label>
    <input type="text" formControlName="appearsOnce" />

    <div formArrayName="formArray">
        <div *ngFor="let control of myForm.controls['formArray'].controls; let i = index">
            <button type="button" (click)="delInput(i)">Delete</button>
            <my-form-sub-component [myForm]="myForm.controls.formArray.controls[i]"></my-form-sub-component>
        </div>
    </div>
    <button type="button" (click)="addInput()">Add</button>
    <button type="submit" [disabled]="!myForm.valid">Save</button>
</form>

Sub-Component HTML

<div [formGroup]="form">
    <label>Property One: </label>
    <input type="text" formControlName="propertyOne"/>

    <label >Property Two: </label>
    <input type="number" formControlName="propertyTwo"/>
</div>

In the above code I basically have a component that represents the base of the form and then each sub-component manages its own FormGroup instance within the FormArray situated inside the base FormGroup. The base template passes along the sub-group to the sub-component and then you can handle validation for the entire form dynamically.

Also, this makes it trivial to re-order component by strategically inserting and removing them from the form. It works with (seemingly) any number of inputs as they don't conflict with names (a big downside of template-driven forms as far as I'm aware) and you still retain pretty much automatic validation. The only "downside" of this approach is, besides writing a little more code, you do have to relearn how forms work. However, this will open up possibilities for much larger and more dynamic forms as you go on.

If you have any questions or want to point out some errors, go ahead. I just typed up the above code based on something I did myself this past week with the names changed and other misc. properties left out, but it should be straightforward. The only major difference between the above code and my own is that I moved all of the form-building to a separate service that's called from the component so it's a bit less messy.

Try with it

$color = \App\Color::take(1)->first();

As of Python 3.5 and PEP484, the literal ellipsis is used to denote certain types to a static type checker when using the typing module.

Example 1:

Arbitrary-length homogeneous tuples can be expressed using one type and ellipsis, for example Tuple[int, ...]

Example 2:

It is possible to declare the return type of a callable without specifying the call signature by substituting a literal ellipsis (three dots) for the list of arguments:

def partial(func: Callable[..., str], *args) -> Callable[..., str]:
    # Body

You can use:

f.Controls[name];

Where f is your form variable. That gives you the control with name name.

intent.putExtra("EXTRA_SESSION_ID",sessionId)
startActivity(intent)

In MainActivity2:

if (intent.hasExtra("EXTRA_SESSION_ID")){

Internally, Javascript strings are all Unicode (actually UCS-2, a subset of UTF-16).

If you're retrieving the JSON files separately via AJAX, then you only need to make sure that the JSON files are served with the correct Content-Type and charset: Content-Type: application/json; charset="utf-8"). If you do that, jQuery should already have interpreted them properly by the time you access the deserialized objects.

Could you post an example of the code you’re using to retrieve the JSON objects?

This is a common problem. Use this instead of getApplicationContext() That should solve your problem

The reason the encoded array is longer by about a quarter is that base-64 encoding uses only six bits out of every byte; that is its reason of existence - to encode arbitrary data, possibly with zeros and other non-printable characters, in a way suitable for exchange through ASCII-only channels, such as e-mail.

The way you get your original array back is by using Convert.FromBase64String:

 byte[] temp_backToBytes = Convert.FromBase64String(temp_inBase64);

Using attr() pointing to an external domain may trigger an error like this in Chrome: "Refused to display document because display forbidden by X-Frame-Options". The workaround to this can be to move the whole iframe HTML code into the script (eg. using .html() in jQuery).

Example:

var divMapLoaded = false;
$("#container").scroll(function() {
    if ((!divMapLoaded) && ($("#map").position().left <= $("#map").width())) {
    $("#map-iframe").html("<iframe id=\"map-iframe\" " +
        "width=\"100%\" height=\"100%\" frameborder=\"0\" scrolling=\"no\" " +
        "marginheight=\"0\" marginwidth=\"0\" " +
        "src=\"http://www.google.it/maps?t=m&amp;cid=0x3e589d98063177ab&amp;ie=UTF8&amp;iwloc=A&amp;brcurrent=5,0,1&amp;ll=41.123115,16.853177&amp;spn=0.005617,0.009943&amp;output=embed\"" +
        "></iframe>");
    divMapLoaded = true;
}

public class StringDemo {
    public static void main(String[] args) {
        String palindrome = "Dot saw I was Tod";
        int len = palindrome.length();
        char[] tempCharArray = new char[len];
        char[] charArray = new char[len];

        // put original string in an array of chars
        for (int i = 0; i < len; i++) {
            tempCharArray[i] = palindrome.charAt(i);
        } 

        // reverse array of chars
        for (int j = 0; j < len; j++) {
            charArray[j] = tempCharArray[len - 1 - j];
        }

        String reversePalindrome =  new String(charArray);
        System.out.println(reversePalindrome);

Put the length into int len and use for loop.

If you think about the performace ,may be you can use "PERFORM" in a function just like this:

 PERFORM 1 FROM skytf.test_2 WHERE id=i LIMIT 1;
  IF FOUND THEN
      RAISE NOTICE ' found record id=%', i;  
  ELSE
      RAISE NOTICE ' not found record id=%', i;  
 END IF;

While everything written below still holds true, Rails 5.2 now includes active_storage, which allows stuff like uploading directly to S3 (or other cloud storage services), image transformations, etc. You should check out the rails guide and decide for yourself what fits your needs.

While there are plenty of gems that solve file uploading pretty nicely (see https://www.ruby-toolbox.com/categories/rails_file_uploads for a list), rails has built-in helpers which make it easy to roll your own solution.

Use the file_field-form helper in your form, and rails handles the uploading for you:

<%= form_for @person do |f| %>
  <%= f.file_field :picture %>
<% end %>

You will have access in the controller to the uploaded file as follows:

uploaded_io = params[:person][:picture]
File.open(Rails.root.join('public', 'uploads', uploaded_io.original_filename), 'wb') do |file|
  file.write(uploaded_io.read)
end

It depends on the complexity of what you want to achieve, but this is totally sufficient for easy file uploading/downloading tasks. This example is taken from the rails guides, you can go there for further information: http://guides.rubyonrails.org/form_helpers.html#uploading-files

When using regular expressions from RegexBuddy's library, make sure to use the same matching modes in your own code as the regex from the library. If you generate a source code snippet on the Use tab, RegexBuddy will automatically set the correct matching options in the source code snippet. If you copy/paste the regex, you have to do that yourself.

In this case, as others pointed out, you missed the case insensitivity option.

gcc will typically use logical shifts on unsigned variables and for left-shifts on signed variables. The arithmetic right shift is the truly important one because it will sign extend the variable.

gcc will will use this when applicable, as other compilers are likely to do.

A radix tree representation would come close to handling this problem, since the radix tree takes advantage of "prefix compression". But it's hard to conceive of a radix tree representation that could represent a single node in one byte -- two is probably about the limit.

But, regardless of how the data is represented, once it is sorted it can be stored in prefix-compressed form, where the numbers 10, 11, and 12 would be represented by, say 001b, 001b, 001b, indicating an increment of 1 from the previous number. Perhaps, then, 10101b would represent an increment of 5, 1101001b an increment of 9, etc.

This works for me:

(In Visual Studio)

1. Open the .rdl file in Designer (right-click on file in Solution Explorer > View Designer)
2. Right-click on the Textbox you are working with, choose Expression

3. In the Set expression for: Value box enter your expression like:

   ="first line of text. Param1 value: " & Parameters!Param1.Value & Environment.NewLine() 
   & "second line of text. Field value: " & Fields!Field1.Value & Environment.NewLine() 
   & "third line of text."
   

Simpler variant of thelsdj's answer:

ls -tr | head -n -5 | xargs --no-run-if-empty rm 

ls -tr displays all the files, oldest first (-t newest first, -r reverse).

head -n -5 displays all but the 5 last lines (ie the 5 newest files).

xargs rm calls rm for each selected file.

I would guess that ISO-format is a good idea. (Wikipedia article, also with time info)

Even without cloning or fetching, you can check the list of tags on the upstream repo with git ls-remote:

git ls-remote --tags /url/to/upstream/repo

(as illustrated in "When listing git-ls-remote why there's “^{}” after the tag name?")

xbmono illustrates in the comments that quotes are needed:

git ls-remote --tags /some/url/to/repo "refs/tags/MyTag^{}"

Note that you can always push your commits and tags in one command with (git 1.8.3+, April 2013):

git push --follow-tags

See Push git commits & tags simultaneously.

Regarding Atlassian SourceTree specifically:

Note that, from this thread, SourceTree ONLY shows local tags.

There is an RFE (Request for Enhancement) logged in SRCTREEWIN-4015 since Dec. 2015.

A simple workaround:

see a list of only unpushed tags?

git push --tags

or check the "Push all tags" box on the "Push" dialog box, all tags will be pushed to your remote.

That way, you will be "sure that they are present in remote so that other developers can pull them".

It's old but thought I'd add my two cents... Not sure if it will work but try using a KeyValuePair:

 List<KeyValuePair<?, ?>> LinkList = new List<KeyValuePair<?, ?>>();
 LinkList.Add(new KeyValuePair<?, ?>(Object, Object));

You'll end up with something like this:

 LinkList[0] = <Object, Object>
 LinkList[1] = <Object, Object>
 LinkList[2] = <Object, Object>

and so on...

My test assembly is 64-bit. From the menu bar at the top of visual studio 2012, I was able to select 'Test' -> 'Test Settings' -> 'Default Processor Architecture' -> 'X64'. After a 'Rebuild Solution' from the 'Build' menu, I was able to see all of my tests in test explorer. Hopefully this helps someone else in the future =D.

Since PHP 5.4 there are constants which can be used by json_encode() to format the json reponse how you want.

To remove backslashes use: JSON_UNESCAPED_SLASHES. Like so:

json_encode($response, JSON_UNESCAPED_SLASHES);

View the PHP documentation for more constants and further information:

http://php.net/manual/en/function.json-encode.php

List of JSON constants:

http://php.net/manual/en/json.constants.php

You do cls.isFilled = True. That overwrites the method called isFilled and replaces it with the value True. That method is now gone and you can't call it anymore. So when you try to call it again you get an error, since it's not there anymore.

The solution is use a different name for the variable than you do for the method.

you can use the below command on terminal

export LC_ALL=C

You can use:

SELECT IDENT_CURRENT('tablename')

to access the latest identity for a perticular table.

e.g. Considering following code:

INSERT INTO dbo.MyTable(columns....) VALUES(..........)

INSERT INTO dbo.YourTable(columns....) VALUES(..........)

SELECT IDENT_CURRENT('MyTable')

SELECT IDENT_CURRENT('YourTable')

This would yield to correct value for corresponding tables.

It returns the last IDENTITY value produced in a table, regardless of the connection that created the value, and regardless of the scope of the statement that produced the value.

IDENT_CURRENT is not limited by scope and session; it is limited to a specified table. IDENT_CURRENT returns the identity value generated for a specific table in any session and any scope.

This expands on a previous answer. The best solution I've found is to make an innocuous CSS attribute that only appears if a CSS3 media query is met, and then have the JS test for that attribute.

So for instance, in the CSS you'd have:

@media screen only and (orientation:landscape)
{
    //  Some innocuous rule here
    body
    {
        background-color: #fffffe;
    }
}
@media screen only and (orientation:portrait)
{
    //  Some innocuous rule here
    body
    {
        background-color: #fffeff;
    }
}

You then go to JavaScript (I'm using jQuery for funsies). Color declarations may be weird, so you may want to use something else, but this is the most foolproof method I've found for testing it. You can then just use the resize event to pick up on switching. Put it all together for:

function detectOrientation(){
    //  Referencing the CSS rules here.
    //  Change your attributes and values to match what you have set up.
    var bodyColor = $("body").css("background-color");
    if (bodyColor == "#fffffe") {
        return "landscape";
    } else
    if (bodyColor == "#fffeff") {
        return "portrait";
    }
}
$(document).ready(function(){
    var orientation = detectOrientation();
    alert("Your orientation is " + orientation + "!");
    $(document).resize(function(){
        orientation = detectOrientation();
        alert("Your orientation is " + orientation + "!");
    });
});

The best part of this is that as of my writing this answer, it doesn't appear to have any effect on desktop interfaces, since they (generally) don't (seem to) pass any argument for orientation to the page.

For anyone who lands here and all the other solutions did not work give this a try. I am using typescript + react and my problem was that I was associating the files in vscode as javascriptreact not typescriptreact so check your settings for the following entries.

   "files.associations": {
    "*.tsx": "typescriptreact",
    "*.ts": "typescriptreact"
  },

Within Jquery.UI, just update the _checkOffset function, so that viewHeight is added to offset.top, before offset is returned.

_checkOffset: function(inst, offset, isFixed) {
    var dpWidth = inst.dpDiv.outerWidth(),
    dpHeight = inst.dpDiv.outerHeight(),
    inputWidth = inst.input ? inst.input.outerWidth() : 0,
    inputHeight = inst.input ? inst.input.outerHeight() : 0,
    viewWidth = document.documentElement.clientWidth + (isFixed ? 0 : $(document).scrollLeft()),
            viewHeight = document.documentElement.clientHeight + (isFixed ? 0 : ($(document).scrollTop()||document.body.scrollTop));
        offset.left -= (this._get(inst, "isRTL") ? (dpWidth - inputWidth) : 0);
        offset.left -= (isFixed && offset.left === inst.input.offset().left) ? $(document).scrollLeft() : 0;
        offset.top -= (isFixed && offset.top === (inst.input.offset().top + inputHeight)) ? ($(document).scrollTop()||document.body.scrollTop) : 0;

        // now check if datepicker is showing outside window viewport - move to a better place if so.
        offset.left -= Math.min(offset.left, (offset.left + dpWidth > viewWidth && viewWidth > dpWidth) ?
            Math.abs(offset.left + dpWidth - viewWidth) : 0);
        offset.top -= Math.min(offset.top, (offset.top + dpHeight > viewHeight && viewHeight > dpHeight) ?
            Math.abs(dpHeight + inputHeight) : 0);
**offset.top = offset.top + viewHeight;**
        return offset;
    },

Unfortunately the native browser present on Android devices not support this type of file. Let's see if in the 4.0 we will be able to do that.

Using new Date().getTime() / 1000 is an incomplete solution for obtaining the seconds, because it produces timestamps with floating-point units.

const timestamp = new Date() / 1000; // 1405792936.933
// Technically, .933 would be milliseconds. 

A better solution would be:

// Rounds the value
const timestamp = Math.round(new Date() / 1000); // 1405792937

// - OR -

// Floors the value
const timestamp = new Date() / 1000 | 0; // 1405792936

Values without floats are also safer for conditional statements, as the float may produce unwanted results. The granularity you obtain with a float may be more than needed.

if (1405792936.993 < 1405792937) // true

If it is only image then JavaScript is not really necessary. Try using this in your html file :

<img src="sample-img-15.jpg" alt="#" height="24" width="100" onContextMenu="return false;" />

Using the below line

SELECT LEFT(subject , 10) FROM tbl

Just did this and UrlSearchParams did the trick Here is my code if it helps someone

import 'url-search-params-polyfill';
const userLogsInOptions = (username, password) => {



// const formData = new FormData();
  const formData = new URLSearchParams();
  formData.append('grant_type', 'password');
  formData.append('client_id', 'entrance-app');
  formData.append('username', username);
  formData.append('password', password);
  return (
    {
      method: 'POST',
      headers: {
        // "Content-Type": "application/json; charset=utf-8",
        "Content-Type": "application/x-www-form-urlencoded",
    },
      body: formData.toString(),
    json: true,
  }
  );
};


const getUserUnlockToken = async (username, password) => {
  const userLoginUri = `${scheme}://${host}/auth/realms/${realm}/protocol/openid-connect/token`;
  const response = await fetch(
    userLoginUri,
    userLogsInOptions(username, password),
  );
  const responseJson = await response.json();
  console.log('acces_token ', responseJson.access_token);
  if (responseJson.error) {
    console.error('error ', responseJson.error);
  }
  console.log('json ', responseJson);
  return responseJson.access_token;
};

First of all, you are in a bad position now - having the task of writing tests for the code you did not originally create and without any changes - nightmare! Talk to your boss and explain, it is not possible to test the code without making it "testable". To make code testable you usually do some important changes;

Regarding private variables. You actually never should do that. Aiming to test private variables is the first sign that something wrong with the current design. Private variables are part of the implementation, tests should focus on behavior rather of implementation details.

Sometimes, private field are exposed to public access with some getter. I do that, but try to avoid as much as possible (mark in comments, like 'used for testing').

Since you have no possibility to change the code, I don't see possibility (I mean real possibility, not like Reflection hacks etc.) to check private variable.

You can do something like this in awk:

awk '{ print $NF }'

Edit: To avoid empty line :

awk 'NF{ print $NF }'

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.

GitHub is the entire site. Gists are a particular service offered on that site, namely code snippets akin to pastebin. However, everything is driven by git revision control, so gists also have complete revision histories.

Simply:

• pop: returns the item at the top then remove it from the stack

• push: add an item onto the top of the stack.

You'll have to jailbreak your device.

you could use it like this :

  $('#formId').submit();

OR

document.formName.submit();

There is a setting inside the PDF file that turns on the allow saving with data bit. However, it requires that you have a copy of Adobe Acrobat installed to change the bit.

The only other option is to print it to a PDF print driver which would save the data merged with the pdf file.

UPDATE: The relevant information from adobe is at: http://www.adobeforums.com/webx?13@@.3bbb313f/7

When you are using Multiple css property with jQuery then you must use the curly Brace in starting and in the end. You are missing the ending curly brace.

function init() {
 $("h1").css("backgroundColor", "yellow");

 $("#myParagraph").css({"background-color":"black","color":"white"});

 $(".bordered").css("border", "1px solid black");
}

You can have a look at this jQuery CSS Selector tutorial.

I've dumped nodemon and ts-node in favor of a much better alternative, ts-node-dev https://github.com/whitecolor/ts-node-dev

Just run ts-node-dev src/index.ts

It sounds like you want something like:

var query = from order in workOrders
            join plan in plans
                 on order.WorkOrderNumber equals plan.WorkOrderNumber
            select new
            {
                order.WorkOrderNumber,
                order.Description,
                plan.ScheduledDate
            };

if you're looking for the equivalent of "adb run myapp.apk"

you can use the script shown in this answer

(linux and mac only - maybe with cygwin on windows)

linux/mac users can also create a script to run an apk with something like the following:

create a file named "adb-run.sh" with these 3 lines:

pkg=$(aapt dump badging $1|awk -F" " '/package/ {print $2}'|awk -F"'" '/name=/ {print $2}')
act=$(aapt dump badging $1|awk -F" " '/launchable-activity/ {print $2}'|awk -F"'" '/name=/ {print $2}')
adb shell am start -n $pkg/$act

then "chmod +x adb-run.sh" to make it executable.

now you can simply:

adb-run.sh myapp.apk

The benefit here is that you don't need to know the package name or launchable activity name. Similarly, you can create "adb-uninstall.sh myapp.apk"

Note: This requires that you have aapt in your path. You can find it under the new build tools folder in the SDK

Late answer, but this is what I use to find and replace inside a text file:

with open("test.txt") as r:
  text = r.read().replace("THIS", "THAT")
with open("test.txt", "w") as w:
  w.write(text)

DEMO

Use the .data() method:

$('div').data('info', '222');

Note that this doesn't create an actual data-info attribute. If you need to create the attribute, use .attr():

$('div').attr('data-info', '222');

Basically, no you have to make three delete statements in a transaction, children first and then parents. Setting up cascading deletes is a good idea if this is not a one-off thing and its existence won't conflict with any existing trigger setup.

This should work, but is slower and feels wrong: System.arraycopy(new float[]{...}, 0, values, 0, 3);

The other simple way, use docker-compose with the following lines:

mysql:
  from: mysql:5.7
  volumes:
    - ./database:/tmp/database
  command: mysqld --init-file="/tmp/database/install_db.sql"

Put your database schema into the ./database/install_db.sql. Every time when you build up your container, the install_db.sql will be executed.

Can you provide your layout xml? Doing so would allow people to recreate the issue with minimal effort.

You might have to set

android:layout_weight="1"

for the item that you want expanded

bool data(sampleData *data)
{
}

You need to tell the method which type of struct you are using. In this case, sampleData.

Note: In this case, you will need to define the struct prior to the method for it to be recognized.

Example:

struct sampleData
{
   int N;
   int M;
   // ...
};

bool data(struct *sampleData)
{

}

int main(int argc, char *argv[]) {

      sampleData sd;
      data(&sd);

}

Note 2: I'm a C guy. There may be a more c++ish way to do this.

I use some css like this (based on css tricks):

@media screen and (min-width: 320px) and (max-width: 767px) and (orientation: portrait) {
  html {
    transform: rotate(-90deg);
    transform-origin: left top;
    width: 100vh;
    height: 100vw;
    overflow-x: hidden;
    position: absolute;
    top: 100%;
    left: 0;
  }
}

To convert a String into Integer, I recommend using parseFloat and NOT parseInt. Here's why:

Using parseFloat:

parseFloat('2.34cms')  //Output: 2.34
parseFloat('12.5')     //Output: 12.5
parseFloat('012.3')    //Output: 12.3

Using parseInt:

parseInt('2.34cms')  //Output: 2
parseInt('12.5')     //Output: 12
parseInt('012.3')    //Output: 12

So if you have noticed parseInt discards the values after the decimals, whereas parseFloat lets you work with floating point numbers and hence more suitable if you want to retain the values after decimals. Use parseInt if and only if you are sure that you want the integer value.

I've been trying to deploy a simple Angular 7 application, to an Azure Web App. Everything worked fine, until the point where you refreshed the page. Doing so, was presenting me with an 500 error - moved content. I've read both on the Angular docs and in around a good few forums, that I need to add a web.config file to my deployed solution and make sure the rewrite rule fallback to the index.html file. After hours of frustration and trial and error tests, I've found the error was quite simple: adding a tag around my file markup.

Here is a sample script that I recently used in a Gateway POST transaction that receives a GET response. Are you using this in a custom C# form? Whatever your purpose, just replace the String fields (username, password, etc.) with the parameters from your form.

private String readHtmlPage(string url)
   {

    //setup some variables

    String username  = "demo";
    String password  = "password";
    String firstname = "John";
    String lastname  = "Smith";

    //setup some variables end

      String result = "";
      String strPost = "username="+username+"&password="+password+"&firstname="+firstname+"&lastname="+lastname;
      StreamWriter myWriter = null;

      HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(url);
      objRequest.Method = "POST";
      objRequest.ContentLength = strPost.Length;
      objRequest.ContentType = "application/x-www-form-urlencoded";

      try
      {
         myWriter = new StreamWriter(objRequest.GetRequestStream());
         myWriter.Write(strPost);
      }
      catch (Exception e) 
      {
         return e.Message;
      }
      finally {
         myWriter.Close();
      }

      HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse();
      using (StreamReader sr = 
         new StreamReader(objResponse.GetResponseStream()) )
      {
         result = sr.ReadToEnd();

         // Close and clean up the StreamReader
         sr.Close();
      }
      return result;
   } 

I only needed to parse IP v4 addresses. My solution based on Chills strategy follows:

def getIP():

    valid = False

    while not valid :

        octets = raw_input( "Remote Machine IP Address:" ).strip().split(".")

        try: valid=len( filter( lambda(item):0<=int(item)<256, octets) ) == 4

        except: valid = False

    return ".".join( octets )

Here is the solution for Ubuntu users

First we have to stop postgresql

sudo /etc/init.d/postgresql stop

Create a new file called /etc/apt/sources.list.d/pgdg.list and add below line

deb http://apt.postgresql.org/pub/repos/apt/ utopic-pgdg main

Follow below commands

wget -q -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update
sudo apt-get install postgresql-9.4
sudo pg_dropcluster --stop 9.4 main 
sudo /etc/init.d/postgresql start

Now we have everything, just need to upgrade it as below

sudo pg_upgradecluster 9.3 main
sudo pg_dropcluster 9.3 main

That's it. Mostly upgraded cluster will run on port number 5433. Check it with below command

sudo pg_lsclusters

There are some cases during development when there is no service yet but you want to simulate it and keep the container alive.

It is very easy to write a bash placeholder that simulates a running service:

while true; do
  sleep 100
done

You replace this by something more serious as the development progress.

In case of Samsung S8 none of the above provided methods were giving proper height of navigation bar so I used the KeyboardHeightProvider keyboard height provider android. And it gave me height in negative values and for my layout positioning I adjusted that value in calculations.

Here is KeyboardHeightProvider.java :

Check if the manifest is a valid xml file. I had the same problem by doing a DOS copy command at the end of the build, and it turns out that for some reason I can not understand "copy" was adding a strange character (->) at the end of the manifest files. The problem was solved by adding "/b" switch to force binary copy.

I like to use gitk name_of_file

This shows a nice list of the changes that happened to a file at each commit, instead of showing the changes to all the files. Makes it easier to track down something that happened.

Update: For a better approach, please refer to Blackus's answer in the same thread.

If you are not averse to using JavaScript and Regex, you can use the below solution to find all width and height properties in the style attribute and replace them with nothing.

//Get the value of style attribute based on element's Id
var originalStyle = document.getElementById('sample_id').getAttribute('style'); 

var regex = new RegExp(/(width:|height:).+?(;[\s]?|$)/g);
//Replace matches with null
var modStyle = originalStyle.replace(regex, ""); 

//Set the modified style value to element using it's Id
document.getElementById('sample_id').setAttribute('style', modStyle); 

Use the Underscore.js findWhere function (http://underscorejs.org/#findWhere):

var purposeObjects = [
    {purpose: "daily"},
    {purpose: "weekly"},
    {purpose: "monthly"}
];

var daily = _.findWhere(purposeObjects, {purpose: 'daily'});

daily would equal:

{"purpose":"daily"}

Here's a fiddle: http://jsfiddle.net/spencerw/oqbgc21x/

To return more than one (if you had more in your array) you could use _.where(...)

Edit: This question gave me an itch, so I put up a JSONP webservice on Google App Engine that returns the clients ip address. Usage:

<script type="application/javascript">
function getip(json){
  alert(json.ip); // alerts the ip address
}
</script>

<script type="application/javascript" src="http://jsonip.appspot.com/?callback=getip"> </script>

Yay, no server proxies needed.

Pure JS can't. If you have a server script under the same domain that prints it out you could send a XMLHttpRequest to read it.

[disclaimer: I'm one of the contributors]

We built a very simple free/opensource component that adds SAML support for ASP.NET apps https://github.com/jitbit/AspNetSaml

Basically it's just one short C# file you can throw into your project (or install via Nuget) and use it with your app

It depends on what you define as the difference. To compare two dates at midnight you can do.

long day1 = ...; // in milliseconds.
long day2 = ...; // in milliseconds.
long days = (day2 - day1) / 86400000;

LoadLibrary does not do what you think it does. It loads the DLL into the memory of the current process, but it does not magically import functions defined in it! This wouldn't be possible, as function calls are resolved by the linker at compile time while LoadLibrary is called at runtime (remember that C++ is a statically typed language).

You need a separate WinAPI function to get the address of dynamically loaded functions: GetProcAddress.

Example

#include <windows.h>
#include <iostream>

/* Define a function pointer for our imported
 * function.
 * This reads as "introduce the new type f_funci as the type: 
 *                pointer to a function returning an int and 
 *                taking no arguments.
 *
 * Make sure to use matching calling convention (__cdecl, __stdcall, ...)
 * with the exported function. __stdcall is the convention used by the WinAPI
 */
typedef int (__stdcall *f_funci)();

int main()
{
  HINSTANCE hGetProcIDDLL = LoadLibrary("C:\\Documents and Settings\\User\\Desktop\\test.dll");

  if (!hGetProcIDDLL) {
    std::cout << "could not load the dynamic library" << std::endl;
    return EXIT_FAILURE;
  }

  // resolve function address here
  f_funci funci = (f_funci)GetProcAddress(hGetProcIDDLL, "funci");
  if (!funci) {
    std::cout << "could not locate the function" << std::endl;
    return EXIT_FAILURE;
  }

  std::cout << "funci() returned " << funci() << std::endl;

  return EXIT_SUCCESS;
}

Also, you should export your function from the DLL correctly. This can be done like this:

int __declspec(dllexport) __stdcall funci() {
   // ...
}

As Lundin notes, it's good practice to free the handle to the library if you don't need them it longer. This will cause it to get unloaded if no other process still holds a handle to the same DLL.

try this

INSERT INTO TABLE1 (COL1 , COL2,COL3) values
('A STRING' , 5 , (select idTable2 from Table2) )
where ...

Some reading to get you started on character encodings: Joel on Software: The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)

By the way - ASP.NET has nothing to do with it. Encodings are universal.

I just changed minSdkVersion="7" in C:\MyApp\platforms\android\CordovaLib\AndroidManifest.xml and it worked.

Steps:

1. Path: C:\MyApp\platforms\android\CordovaLib\AndroidManifest.xml
2. Value: <uses-sdk android:minSdkVersion="7"/>

3. Ran command in new cmd prompt:

   C:\MyApp>phonegap build android --debug [phonegap] executing 'cordova build android --debug'... [phonegap] completed 'cordova build android --debug'

According to Oracle's installation notes, you should download/install JDK for the correct system. For your convenience, I have linked to it from the sentence above. If you still encounter problems, leave a comment. I have written some quick code that will tell you if your JVM is 64 or 32-bit, below. I'd suggest you run this class and leave a comment as to its output:

public class CheckMemoryMode {
    public static void main(String[] args) {
        System.err.println(System.getProperty("sun.arch.data.model"));
    }
}

Use df.to_dict('records') -- gives the output without having to transpose externally.

In [2]: df.to_dict('records')
Out[2]:
[{'customer': 1L, 'item1': 'apple', 'item2': 'milk', 'item3': 'tomato'},
 {'customer': 2L, 'item1': 'water', 'item2': 'orange', 'item3': 'potato'},
 {'customer': 3L, 'item1': 'juice', 'item2': 'mango', 'item3': 'chips'}]

You need this:

window.onload = function(){
    var elCheckBox=document.getElementById("cbxTodos");
    elCheckBox.onchange =function (){
        alert("como ves");
    }
};

Assuming you're the administrator of the machine, Ubuntu has granted you the right to sudo to run any command as any user.
Also assuming you did not restrict the rights in the pg_hba.conf file (in the /etc/postgresql/9.1/main directory), it should contain this line as the first rule:

# Database administrative login by Unix domain socket  
local   all             postgres                                peer

(About the file location: 9.1 is the major postgres version and main the name of your "cluster". It will differ if using a newer version of postgres or non-default names. Use the pg_lsclusters command to obtain this information for your version/system).

Anyway, if the pg_hba.conf file does not have that line, edit the file, add it, and reload the service with sudo service postgresql reload.

Then you should be able to log in with psql as the postgres superuser with this shell command:

sudo -u postgres psql

Once inside psql, issue the SQL command:

ALTER USER postgres PASSWORD 'newpassword';

In this command, postgres is the name of a superuser. If the user whose password is forgotten was ritesh, the command would be:

ALTER USER ritesh PASSWORD 'newpassword';

References: PostgreSQL 9.1.13 Documentation, Chapter 19. Client Authentication

Keep in mind that you need to type postgres with a single S at the end

If leaving the password in clear text in the history of commands or the server log is a problem, psql provides an interactive meta-command to avoid that, as an alternative to ALTER USER ... PASSWORD:

\password username

It asks for the password with a double blind input, then hashes it according to the password_encryption setting and issue the ALTER USER command to the server with the hashed version of the password, instead of the clear text version.

There might be a semicolon or bracket missing a line before your pasted line.

It seems fine to me; every string is allowed as an array index.

To delete cookie you just need to set the value to NULL:

"If you've set a cookie with nondefault values for an expiration time, path, or domain, you must provide those same values again when you delete the cookie for the cookie to be deleted properly." Quote from "Learning PHP5" book.

So this code should work(works for me):

Setting the cookie: setcookie('foo', 'bar', time() + 60 * 5);

Deleting the cookie: setcookie('foo', '', time() + 60 * 5);

But i noticed that everybody is setting the expiry date to past, is that necessary, and why?

In the "volumes" tab, you have to mount it first. Then it appears on the desktop as if it were an external USB. All the data is inside it. :D

Sebastian's answer was the only answer that worked for me while examining a xaml document. If, like me, you'd like a list of all the elements then the method would look a lot like Sebastian's answer above but just returning a list...

    private static List<XElement> GetElements(XDocument doc, string elementName)
    {
        List<XElement> elements = new List<XElement>();

        foreach (XNode node in doc.DescendantNodes())
        {
            if (node is XElement)
            {
                XElement element = (XElement)node;
                if (element.Name.LocalName.Equals(elementName))
                    elements.Add(element);
            }
        }
        return elements;
    }

Call it thus:

var elements = GetElements(xamlFile, "Band");

or in the case of my xaml doc where I wanted all the TextBlocks, call it thus:

var elements = GetElements(xamlFile, "TextBlock");

An iframe is a 'hole' in your page that displays another web page inside of it. The contents of the iframe is not in any shape or form part of your parent page.

As others have stated, your options are:

• give the file that is being loaded in the iframe the necessary CSS
• if the file in the iframe is from the same domain as your parent, then you can access the DOM of the document in the iframe from the parent.

If the name column were a JSON array (like '["a","b","c"]'), then you could extract/unpack it with JSON_TABLE() (available since MySQL 8.0.4):

select t.id, j.name
from mytable t
join json_table(
  t.name,
  '$[*]' columns (name varchar(50) path '$')
) j;

Result:

| id  | name |
| --- | ---- |
| 1   | a    |
| 1   | b    |
| 1   | c    |
| 2   | b    |

View on DB Fiddle

If you store the values in a simple CSV format, then you would first need to convert it to JSON:

select t.id, j.name
from mytable t
join json_table(
  replace(json_array(t.name), ',', '","'),
  '$[*]' columns (name varchar(50) path '$')
) j

Result:

| id  | name |
| --- | ---- |
| 1   | a    |
| 1   | b    |
| 1   | c    |
| 2   | b    |

Here is an elegant way to do similar thing. But why do partly JSON unmarshal? That doesn't make sense.

1. Create your structs for the Chat.
2. Decode json to the Struct.
3. Now you can access everything in Struct/Object easily.

Look below at the working code. Copy and paste it.

import (
   "bytes"
   "encoding/json" // Encoding and Decoding Package
   "fmt"
 )

var messeging = `{
"say":"Hello",
"sendMsg":{
    "user":"ANisus",
    "msg":"Trying to send a message"
   }
}`

type SendMsg struct {
   User string `json:"user"`
   Msg  string `json:"msg"`
}

 type Chat struct {
   Say     string   `json:"say"`
   SendMsg *SendMsg `json:"sendMsg"`
}

func main() {
  /** Clean way to solve Json Decoding in Go */
  /** Excellent solution */

   var chat Chat
   r := bytes.NewReader([]byte(messeging))
   chatErr := json.NewDecoder(r).Decode(&chat)
   errHandler(chatErr)
   fmt.Println(chat.Say)
   fmt.Println(chat.SendMsg.User)
   fmt.Println(chat.SendMsg.Msg)

}

 func errHandler(err error) {
   if err != nil {
     fmt.Println(err)
     return
   }
 }

Using the Windows FTP client you would want to use the -s:filename option to specify a script for the FTP client to run. The documentation specifically points out that you should not try to pipe input into the FTP client with a < character.

Execution of the script will start immediately, so it does work for username/password.

However, the security of this setup is questionable since you now have a username and password for the FTP server visible to anyone who decides to look at your batch file.

Either way, you can generate the script file on the fly from the batch file and then pass it to the FTP client like so:

@echo off

REM Generate the script. Will overwrite any existing temp.txt
echo open servername> temp.txt
echo username>> temp.txt
echo password>> temp.txt
echo get %1>> temp.txt
echo quit>> temp.txt

REM Launch FTP and pass it the script
ftp -s:temp.txt

REM Clean up.
del temp.txt

Replace servername, username, and password with your details and the batch file will generate the script as temp.txt launch ftp with the script and then delete the script.

If you are always getting the same file you can replace the %1 with the file name. If not you just launch the batchfile and provide the name of the file to get as an argument.

2015: Newer LINQ & lambda.

1. As this is an old Q (and Answer), just thought to update it with newer 2015 methods.
2. The original "space" can refer to non-space whitespace (ie, tab, newline, paragraph separator, line feed, carriage return, etc, etc).
3. Also, Trim() only remove the spaces from the front/back of the string, it does not remove spaces inside the string; eg: " Leading and Trailing Spaces " will become "Leading and Trailing Spaces", but the spaces inside are still present.

Function RemoveWhitespace(fullString As String) As String
    Return New String(fullString.Where(Function(x) Not Char.IsWhiteSpace(x)).ToArray())
End Function

This will remove ALL (white)-space, leading, trailing and within the string.

For those who might be in need for a solution in pug template engine and NodeJs back-end, you can use this:

If values are not boolean(IE: true or false), code below works fine:

input(type='radio' name='sex' value='male' checked=(dbResult.sex ==='male') || (dbResult.sex === 'newvalue') )
input(type='radio' name='sex' value='female' checked=(dbResult.sex ==='female) || (dbResult.sex === 'newvalue'))

If values are boolean(ie: true or false), use this instead:

input(type='radio' name='isInsurable' value='true' checked=singleModel.isInsurable || (singleModel.isInsurable === 'true') )
input(type='radio' name='isInsurable' value='false' checked=!singleModel.isInsurable || (singleModel.isInsurable === 'false'))

the reason for this || operator is to re-display new values if editing fails due to validation error and you have a logic to send back the new values to your front-end

You can use display: table-cell in order to render the div as a table cell and then use vertical-align like you would do in a normal table cell.

#AlertDiv {
    display: table-cell;
    vertical-align: middle;
    text-align: center;
}

You can try it here: http://jsfiddle.net/KaXY5/424/

It's not possible to use an array like that in PDO.

You need to build a string with a parameter (or use ?) for each value, for instance:

:an_array_0, :an_array_1, :an_array_2, :an_array_3, :an_array_4, :an_array_5

Here's an example:

<?php
$ids = array(1,2,3,7,8,9);
$sqlAnArray = join(
    ', ',
    array_map(
        function($index) {
            return ":an_array_$index";
        },
        array_keys($ids)
    )
);
$db = new PDO(
    'mysql:dbname=mydb;host=localhost',
    'user',
    'passwd'
);
$stmt = $db->prepare(
    'SELECT *
     FROM table
     WHERE id IN('.$sqlAnArray.')'
);
foreach ($ids as $index => $id) {
    $stmt->bindValue("an_array_$index", $id);
}

If you want to keep using bindParam, you may do this instead:

foreach ($ids as $index => $id) {
    $stmt->bindParam("an_array_$index", $ids[$id]);
}

If you want to use ? placeholders, you may do it like this:

<?php
$ids = array(1,2,3,7,8,9);
$sqlAnArray = '?' . str_repeat(', ?', count($ids)-1);
$db = new PDO(
    'mysql:dbname=dbname;host=localhost',
    'user',
    'passwd'
);
$stmt = $db->prepare(
    'SELECT *
     FROM phone_number_lookup
     WHERE country_code IN('.$sqlAnArray.')'
);
$stmt->execute($ids);

If you don't know if $ids is empty, you should test it and handle that case accordingly (return an empty array, or return a Null Object, or throw an exception, ...).

This problem is basically seen because of case sensitive file name. for example if you save file as index.jadge than its mane on route it should be "index" not "Index" in windows this is okay but in linux like server this will create issue.

1) if file name is index.jadge

app.get('/', function(req, res){
      res.render("index");
});

2) if file name is Index.jadge

app.get('/', function(req, res){
      res.render("Index");
});

The following code will produce a secure random number between 0 and 255:

extension UInt8 {
  public static var random: UInt8 {
    var number: UInt8 = 0
    _ = SecRandomCopyBytes(kSecRandomDefault, 1, &number)
    return number
  }
}

You call it like this:

print(UInt8.random)

For bigger numbers it becomes more complicated.
This is the best I could come up with:

extension UInt16 {
  public static var random: UInt16 {
    let count = Int(UInt8.random % 2) + 1
    var numbers = [UInt8](repeating: 0, count: 2)
    _ = SecRandomCopyBytes(kSecRandomDefault, count, &numbers)
    return numbers.reversed().reduce(0) { $0 << 8 + UInt16($1) }
  }
}

extension UInt32 {
  public static var random: UInt32 {
    let count = Int(UInt8.random % 4) + 1
    var numbers = [UInt8](repeating: 0, count: 4)
    _ = SecRandomCopyBytes(kSecRandomDefault, count, &numbers)
    return numbers.reversed().reduce(0) { $0 << 8 + UInt32($1) }
  }
}

These methods use an extra random number to determine how many UInt8s are going to be used to create the random number. The last line converts the [UInt8] to UInt16 or UInt32.

I don't know if the last two still count as truly random, but you can tweak it to your likings :)

I am using Ansible 1.9.4 and this is what worked for me -

- local_action: copy content="{{ foo_result.stdout }}" dest="/path/to/destination/file"

ASCII isn't in it any more. Using UTF-8 encoding means that you aren't using ASCII encoding. What you should use the escaping mechanism for is what the RFC says:

All Unicode characters may be placed within the quotation marks except for the characters that must be escaped: quotation mark, reverse solidus, and the control characters (U+0000 through U+001F)

I found a solution using AutoLayout in StoryBoard.

1) Set no of lines to 0 and text alignment to Left.

2) Set height constraint.

3) The height Constraint should be in Relation - Less Than or Equal

4)

   override func viewWillLayoutSubviews() {
        sampleLabel.sizeToFit()
    }

I got the result as follows :

This will work for a multiple row df having the dataframe as df with the same name of the columns in the df as the db.

tuples = list(df.itertuples(index=False, name=None))

columns_list = df.columns.tolist()
marks = ['?' for _ in columns_list]
columns_list = f'({(",".join(columns_list))})'
marks = f'({(",".join(marks))})'

table_name = 'whateveryouwant'

c.executemany(f'INSERT OR REPLACE INTO {table_name}{columns_list} VALUES {marks}', tuples)
conn.commit()

There is an animationend Event that can be observed see documentation here, also for css transition animations you could use the transitionend event

There is no need for additional libraries these all work with vanilla JS

document.getElementById("myDIV").addEventListener("transitionend", myEndFunction);_x000D_
function myEndFunction() {_x000D_
 this.innerHTML = "transition event ended";_x000D_
}

#myDIV {transition: top 2s; position: relative; top: 0;}_x000D_
div {background: #ede;cursor: pointer;padding: 20px;}

<div id="myDIV" onclick="this.style.top = '55px';">Click me to start animation.</div>

this is nice and simple and gets all the nodes.

also try inputting an ip instead of a domain name and check out those results too!

This issue (https://bugs.eclipse.org/394042) is fixed in m2e 1.5.0 which is available for Eclipse Kepler and Luna from this p2 repo :

http://download.eclipse.org/technology/m2e/releases/1.5

If you also use m2e-wtp, you'll need to install m2e-wtp 1.1.0 as well :

http://download.eclipse.org/m2e-wtp/releases/luna/1.1

You can always use multiplication if you don't immediately recall the .empty or .full methods:

>>> np.nan * np.ones(shape=(3,2))
array([[ nan,  nan],
       [ nan,  nan],
       [ nan,  nan]])

Of course it works with any other numerical value as well:

>>> 42 * np.ones(shape=(3,2))
array([[ 42,  42],
       [ 42,  42],
       [ 42, 42]])

But the @u0b34a0f6ae's accepted answer is 3x faster (CPU cycles, not brain cycles to remember numpy syntax ;):

$ python -mtimeit "import numpy as np; X = np.empty((100,100));" "X[:] = np.nan;"

$ python -mtimeit "import numpy as np; X = np.ones((100,100));" "X *= np.nan;"

If you need to be able to compile code in environments that support the C++11 standard, but also need to be able to compile that same code in environments that don't support it, you could use a function macro to choose between std::round() and a custom function for each system. Just pass -DCPP11 or /DCPP11 to the C++11-compliant compiler (or use its built-in version macros), and make a header like this:

// File: rounding.h
#include <cmath>

#ifdef CPP11
    #define ROUND(x) std::round(x)
#else    /* CPP11 */
    inline double myRound(double x) {
        return (x >= 0.0 ? std::floor(x + 0.5) : std::ceil(x - 0.5));
    }

    #define ROUND(x) myRound(x)
#endif   /* CPP11 */

For a quick example, see http://ideone.com/zal709 .

This approximates std::round() in environments that aren't C++11-compliant, including preservation of the sign bit for -0.0. It may cause a slight performance hit, however, and will likely have issues with rounding certain known "problem" floating-point values such as 0.49999999999999994 or similar values.

Alternatively, if you have access to a C++11-compliant compiler, you could just grab std::round() from its <cmath> header, and use it to make your own header that defines the function if it's not already defined. Note that this may not be an optimal solution, however, especially if you need to compile for multiple platforms.

    }
}

Installing Miniconda on Raspberry Pi and adding Python 3.5 / 3.6

Skip the first section if you have already installed Miniconda successfully.

Installation of Miniconda on Raspberry Pi

wget http://repo.continuum.io/miniconda/Miniconda3-latest-Linux-armv7l.sh
sudo md5sum Miniconda3-latest-Linux-armv7l.sh
sudo /bin/bash Miniconda3-latest-Linux-armv7l.sh

Accept the license agreement with yes

When asked, change the install location: /home/pi/miniconda3

Do you wish the installer to prepend the Miniconda3 install location to PATH in your /root/.bashrc ? yes

Now add the install path to the PATH variable:

sudo nano /home/pi/.bashrc

Go to the end of the file .bashrc and add the following line:

export PATH="/home/pi/miniconda3/bin:$PATH"

Save the file and exit.

To test if the installation was successful, open a new terminal and enter

conda

If you see a list with commands you are ready to go.

But how can you use Python versions greater than 3.4 ?

Adding Python 3.5 / 3.6 to Miniconda on Raspberry Pi

After the installation of Miniconda I could not yet install Python versions higher than Python 3.4, but i needed Python 3.5. Here is the solution which worked for me on my Raspberry Pi 4:

First i added the Berryconda package manager by jjhelmus (kind of an up-to-date version of the armv7l version of Miniconda):

conda config --add channels rpi

Only now I was able to install Python 3.5 or 3.6 without the need for compiling it myself:

conda install python=3.5
conda install python=3.6

Afterwards I was able to create environments with the added Python version, e.g. with Python 3.5:

conda create --name py35 python=3.5

The new environment "py35" can now be activated:

source activate py35

Using Python 3.7 on Raspberry Pi

Currently Jonathan Helmus, who is the developer of berryconda, is working on adding Python 3.7 support, if you want to see if there is an update or if you want to support him, have a look at this pull request. (update 20200623) berryconda is now inactive, This project is no longer active, no recipe will be updated and no packages will be added to the rpi channel. If you need to run Python 3.7 on your Pi right now, you can do so without Miniconda. Check if you are running the latest version of Raspbian OS called Buster. Buster ships with Python 3.7 preinstalled (source), so simply run your program with the following command:

Python3.7 app-that-needs-python37.py

I hope this solution will work for you too!

In recent browsers you can use:

Object.keys(obj.Data).length

See MDN

For older browsers, use the for-in loop in Michael Geary's answer.

You could also set it in the create table statement.

`CREATE TABLE(...) AUTO_INCREMENT=1000`

those various ways of switch ...

# by index
switch(1, "one", "two")
## [1] "one"


# by index with complex expressions
switch(2, {"one"}, {"two"})
## [1] "two"


# by index with complex named expression
switch(1, foo={"one"}, bar={"two"})
## [1] "one"


# by name with complex named expression
switch("bar", foo={"one"}, bar={"two"})
## [1] "two"

You'll have problems creating lists without commas. It shouldn't be too hard to transform your data so that it uses commas as separating character.

Once you have commas in there, it's a relatively simple list creation operations:

array1 = [1,2,3]
array2 = [4,5,6]

array3 = [array1, array2]

array4 = [7,8,9]
array5 = [10,11,12]

array3 = [array3, [array4, array5]]

When testing we get:

print(array3)

[[[1, 2, 3], [4, 5, 6]], [[7, 8, 9], [10, 11, 12]]]

And if we test with indexing it works correctly reading the matrix as made up of 2 rows and 2 columns:

array3[0][1]
[4, 5, 6]

array3[1][1]
[10, 11, 12]

Hope that helps.

if not exists (select * from sysobjects where name='cars' and xtype='U')
    create table cars (
        Name varchar(64) not null
    )
go

The above will create a table called cars if the table does not already exist.

To display the query string:

print_r($this->db->last_query());    

To display the query result:

print_r($query);

The Profiler Class will display benchmark results, queries you have run, and $_POST data at the bottom of your pages. To enable the profiler place the following line anywhere within your Controller methods:

$this->output->enable_profiler(TRUE);

Besides the methods described in other answers (sp_depends system stored procedure, SQL Server dynamic management functions) you can also view dependencies between SQL Server objects - from SSMS.

You can use the View Dependencies option from SSMS. From the Object Explorer pane, right click on the object and from the context menu, select the View Dependencies option

I myself prefer a 3rd party dependency viewer called ApexSQL Search. It is a free add-in, which integrates into SSMS and Visual Studio for SQL object and data text search, extended property management, safe object rename, and relationship visualization.

my working solution to remove fragment page from view pager

public class MyFragmentAdapter extends FragmentStatePagerAdapter {

    private ArrayList<ItemFragment> pages;

    public MyFragmentAdapter(FragmentManager fragmentManager, ArrayList<ItemFragment> pages) {
        super(fragmentManager);
        this.pages = pages;
    }

    @Override
    public Fragment getItem(int index) {
        return pages.get(index);
    }

    @Override
    public int getCount() {
        return pages.size();
    }

    @Override
    public int getItemPosition(Object object) {
        int index = pages.indexOf (object);

        if (index == -1)
            return POSITION_NONE;
        else
            return index;
    }
}

And when i need to remove some page by index i do this

pages.remove(position); // ArrayList<ItemFragment>
adapter.notifyDataSetChanged(); // MyFragmentAdapter

Here it is my adapter initialization

MyFragmentAdapter adapter = new MyFragmentAdapter(getSupportFragmentManager(), pages);
viewPager.setAdapter(adapter);

You can also use SET IDENTITY INSERT to allow you to insert values into an identity column.

Example:

SET IDENTITY_INSERT dbo.Tool ON
GO

And then you can insert into an identity column the values you need.

With C++11, you don't even need the length/size. As long as the string is not empty, you can do the following:

if (!st.empty())
  st.erase(std::prev(st.end())); // Erase element referred to by iterator one
                                 // before the end

I often use this script to get Time from DateTime:

SELECT CONVERT(VARCHAR(9),RIGHT(YOURCOLUMN_DATETIME,9),108) FROM YOURTABLE

I usually manually set the port that I am listening on in the app.js file (assuming you are using express.js

var server = app.listen(8080, function() {
    console.log('Ready on port %d', server.address().port);
});

This will log Ready on port 8080 to your console.

Change column type to LONGTEXT

I realize this question was asked and answered a long time ago, but the answers don't give what I feel is the simplest solution. It's almost always a good idea to avoid loops whenever possible, and matplotlib's plot is capable of plotting multiple lines with one command. If x and y are arrays, then plot draws one line for every column.

In your case, you can do the following:

x=np.array([-1 ,0.5 ,1,-0.5])
xx = np.vstack([x[[0,2]],x[[1,3]]])
y=np.array([ 0.5,  1, -0.5, -1])
yy = np.vstack([y[[0,2]],y[[1,3]]])
plt.plot(xx,yy, '-o')

Have a long list of x's and y's, and want to connect adjacent pairs?

xx = np.vstack([x[0::2],x[1::2]])
yy = np.vstack([y[0::2],y[1::2]])

Want a specified (different) color for the dots and the lines?

plt.plot(xx,yy, '-ok', mfc='C1', mec='C1')

Start by figuring out what your current working directory is for your running script.
Add this line at the beginning:

puts Dir.pwd.

This will tell you in which current working directory ruby is running your script. You will most likely see it's not where you assume it is. Then make sure you're specifying pathnames properly for windows. See the docs here how to properly format pathnames for windows:

http://www.ruby-doc.org/core/classes/IO.html

Then either use Dir.chdir to change the working directory to the place where text.txt is, or specify the absolute pathname to the file according to the instructions in the IO docs above. That SHOULD do it...

EDIT

Adding a 3rd solution which might be the most convenient one, if you're putting the text files among your script files:

Dir.chdir(File.dirname(__FILE__))

This will automatically change the current working directory to the same directory as the .rb file that is running the script.

Check out Javascript's Array API for details on the exact syntax for Array methods. Modifying your code to use the correct syntax would be:

var array = [];
calendars.forEach(function(item) {
    array.push(item.id);
});

console.log(array);

You can also use the map() method to generate an Array filled with the results of calling the specified function on each element. Something like:

var array = calendars.map(function(item) {
    return item.id;
});

console.log(array);

And, since ECMAScript 2015 has been released, you may start seeing examples using let or const instead of var and the => syntax for creating functions. The following is equivalent to the previous example (except it may not be supported in older node versions):

let array = calendars.map(item => item.id);
console.log(array);

Do it like this:

$("#elem").get(0).style.width= "100px!important";

worked for me to open new tab on google-chrome:

webbrowser.open_new_tab("http://www.google.com")

Requests is not a built in module (does not come with the default python installation), so you will have to install it:

OSX/Linux

Use $ pip install requests (or pip3 install requests for python3) if you have pip installed. If pip is installed but not in your path you can use python -m pip install requests (or python3 -m pip install requests for python3)

Alternatively you can also use sudo easy_install -U requests if you have easy_install installed.

Alternatively you can use your systems package manager:

For centos: yum install python-requests For Ubuntu: apt-get install python-requests

Windows

Use pip install requests (or pip3 install requests for python3) if you have pip installed and Pip.exe added to the Path Environment Variable. If pip is installed but not in your path you can use python -m pip install requests (or python3 -m pip install requests for python3)

Alternatively from a cmd prompt, use > Path\easy_install.exe requests, where Path is your Python*\Scripts folder, if it was installed. (For example: C:\Python32\Scripts)

If you manually want to add a library to a windows machine, you can download the compressed library, uncompress it, and then place it into the Lib\site-packages folder of your python path. (For example: C:\Python27\Lib\site-packages)

From Source (Universal)

For any missing library, the source is usually available at https://pypi.python.org/pypi/. You can download requests here: https://pypi.python.org/pypi/requests

On mac osx and windows, after downloading the source zip, uncompress it and from the termiminal/cmd run python setup.py install from the uncompressed dir.

\t in a string marks an escape sequence for a tab character. For a literal \, use \\.

For NodeJS I would get the file name from the res.url, write the header for the file by getting the extension of the file with path.extname, create a read stream for the file, and pipe the response.

const http = require('http');
const fs = require('fs');
const path = require('path');
const port = process.env.PORT || 3000;

const server = http.createServer((req, res) => {
    let filePath = path.join(
        __dirname,
        "public",
        req.url === "/" ? "index.html" : req.url
    );

    let extName = path.extname(filePath);
    let contentType = 'text/html';

    switch (extName) {
        case '.css':
            contentType = 'text/css';
            break;
        case '.js':
            contentType = 'text/javascript';
            break;
        case '.json':
            contentType = 'application/json';
            break;
        case '.png':
            contentType = 'image/png';
            break;
        case '.jpg':
            contentType = 'image/jpg';
            break;
    }

    console.log(`File path: ${filePath}`);
    console.log(`Content-Type: ${contentType}`)

    res.writeHead(200, {'Content-Type': contentType});

    const readStream = fs.createReadStream(filePath);
    readStream.pipe(res);
});

server.listen(port, (err) => {
    if (err) {
        console.log(`Error: ${err}`)
    } else {
        console.log(`Server listening at port ${port}...`);
    }
});

You're using JSTL 2.0 right? You don't need to put <c:out/> around all variables. Have you tried something like this?

<c:forEach items="${myParams.items}" var="currentItem" varStatus="stat">
  <c:set var="myVar" value="${myVar}${currentItem}" />
</c:forEach>

Edit: Beaten by the above

function get_when($date) {

    $current = strtotime(date('Y-m-d H:i'));

    $date_diff = $date - $current;
    $difference = round($date_diff/(60*60*24));

    if($difference >= 0) {
            return 'Today';
    } else if($difference == -1) {
            return 'Yesterday';
    } else if($difference == -2 || $difference == -3  || $difference == -4 || $difference == -5) {
            return date('l', $date);
    } else {
            return ('on ' . date('jS/m/y', $date));
    }

}

get_when(date('Y-m-d H:i', strtotime($your_targeted_date)));

Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.

I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.

If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.

Here is a quick way to do it in 2021 using the Anaconda Navigator. This is the most reliable way to do it, unless you want to create environments programmatically which I don't think is the case for most users:

1. Open Anaconda Navigator.
2. Click on Environments > Create and give a name to your environment. Be sure to change Python/R Kernel version if needed.

3. Go "Home" and click on "Install" under the Spyder box.

4. Click "Launch/Run"

There are still a few minor bugs when setting up your environment, most of them should be solved by restarting the Navigator.

If you find a bug, please help us posting it in the Anaconda Issues bug-tracker too! If you run into trouble creating the environment or if the environment was not correctly created you can double check what got installed: Clicking the "Environments" opens a management window showing installed packages. Search and select Spyder-related packages and then click on "Apply" to install them.

this worked for me:

ALTER TABLE [Table] 
Alter COLUMN [Column] VARCHAR(50) not null;

"\t" not '\t', php doesnt escape in single quotes

You can use a static lookup map to avoid the exception and return a null, then throw as you'd like:

public enum Mammal {
    COW,
    MOUSE,
    OPOSSUM;

    private static Map<String, Mammal> lookup = 
            Arrays.stream(values())
                  .collect(Collectors.toMap(Enum::name, Function.identity()));

    public static Mammal getByName(String name) {
        return lookup.get(name);
    }
}

You delete first from the database and then you update your datagridview:

//let's suppose delete(id) is a method which will delete a row from the database and
// returns true when it is done
int id = 0;
//we suppose that the first column in the datagridview is the ID of the ROW :
foreach (DataGridViewRow row in this.dataGridView1.SelectedRows)
   id = Convert.ToInt32(row.Cells[0].Value.ToString());
if(delete(id))                               
   this.dataGridView1.Rows.RemoveAt(this.dataGridView1.SelectedRows[0].Index);
//else show message error!

What about this one?

I think this is always the latest version - Correct me, if I'm wrong.

In Visual Studio 2008 I added the app.config file to the test project as an existing item and selected copy as link in order to make sure it's not duplicated. That way I only have one copy in my solution. With several test projects it comes in really handy!

I've just solved the problem on an Android 4.0.2 device (GN) and the only version working for this device/version was similar to the first 5-starred with CALL_PHONE permission and the answer:

Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:123456789"));
startActivity(callIntent);

With any other solution i got the ActivityNotFoundException on this device/version. How about the older versions? Would someone give feedback?

// Step 1 :- Register NotificationCenter

ViewDidLoad() {

   self.yourtextfield.becomefirstresponder()

   // Register your Notification, To know When Key Board Appears.
    NotificationCenter.default.addObserver(self, selector: #selector(SelectVendorViewController.keyboardWillShow(notification:)), name: NSNotification.Name.UIKeyboardWillShow, object: nil)

   // Register your Notification, To know When Key Board Hides.
    NotificationCenter.default.addObserver(self, selector: #selector(SelectVendorViewController.keyboardWillHide(notification:)), name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}

// Step 2 :- These Methods will be called Automatically when Keyboard appears Or Hides

    func keyboardWillShow(notification:NSNotification) {
        let userInfo:NSDictionary = notification.userInfo! as NSDictionary
        let keyboardFrame:NSValue = userInfo.value(forKey: UIKeyboardFrameEndUserInfoKey) as! NSValue
        let keyboardRectangle = keyboardFrame.cgRectValue
        let keyboardHeight = keyboardRectangle.height
        tblViewListData.frame.size.height = fltTblHeight-keyboardHeight
    }

    func keyboardWillHide(notification:NSNotification) {
        tblViewListData.frame.size.height = fltTblHeight
    }

The man page explains that you can enter command line mode in a running session by typing Ctrl+A, :, then issuing the scrollback <num> command.
