Your if statements are checking for int values. raw_input returns a string. Change the following line:

tSizeAns = raw_input() 

to

tSizeAns = int(raw_input()) 

Look at java.lang.BigDecimal, may solve your problem.

http://docs.oracle.com/javase/7/docs/api/java/math/BigDecimal.html

Use properties file. Here is a good start: http://www.mkyong.com/java/java-properties-file-examples/

In my case using Angular and Spring Boot I solved that issue in my SecurityConfig:

http.csrf().disable().cors().disable()
            .authorizeRequests()
            .antMatchers(HttpMethod.POST, "/register")
            .anonymous()
            .anyRequest().authenticated()
            .and()
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);

Or replace that line to:

http.csrf().disable().cors().and()

And other test option is to delete dependency from pom.xml and other code depend on it. It's like turn off security from Spring:

<dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-security</artifactId>
     <version>2.3.3.RELEASE</version>
</dependency>

Following actions worked for me.

1.Go to Project in toolbar -> Unchecked "Build Automatically"

2.In POM File,Downgrade the spring-boot version to 2.1.4 RELEASE.

3.Right Click on Project name -> Select Maven -> Click on "Update Project". ->OK Wait till all the maven dependency to get downloaded(Need internet).

Ended up to have a file named polyfill.js in projectpath\src\polyfill.js That file only contains this line: import 'core-js'; this polyfills not only es-6, but is the correct way to use core-js since version 3.0.0.

I added the polyfill.js to my webpack-file entry attribute like this:

entry: ['./src/main.scss', './src/polyfill.js', './src/main.jsx']

Works perfectly.

I also found some more information here : https://github.com/zloirock/core-js/issues/184

The library author (zloirock) claims:

ES6 changes behaviour almost all features added in ES5, so core-js/es6 entry point includes almost all of them. Also, as you wrote, it's required for fixing broken browser implementations.

(Quotation https://github.com/zloirock/core-js/issues/184 from zloirock)

So I think import 'core-js'; is just fine.

You are returning Observable<Product> and expecting it to be Product[] inside subscribe callback.

The Type returned from http.get() and getProducts() should be Observable<Product[]>

public getProducts(): Observable<Product[]> {
    return this.http.get<Product[]>(`api/products/v1/`);
}

I had the same problem here. In my case I need to use an old version of JDK and I'm using sdkmanager to manage the versions of JDK, so, I changed the version of the virtual machine to 1.8.

sdk use java 8.0.222.j9-adpt

After that, the app runs as expected here.

I have faced it on 04/2020. These are the options that I tried and the last solution get me through.

Problem:

Requests module works fine when I use in Spyder IDE but when I try to execute the script in windows it fails with SSL error. It works fine for HTTP requests but for HTTPS requests i got SSL error.

1. I tired with Veify=True, False , also with Certs. Same error.
2. Removed Certifi - conda remove certifi - Did not work Updated
3. openssl , certifi - Still same error ( Refer : https://github.com/ContinuumIO/anaconda-issues/issues/494) Added
4. the path variables - Same error
5. Created new environment in Anaconda - same error

Solution that fixed it:

Solution from: https://github.com/conda/conda/issues/8273

I have copied the following files from Anaconda3\Library\bin to \Anaconda3\DLL

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

Problem

git clone https://github.com/rojarfast1991/TestGit.git fatal: protocol 'https' is not supported

Solution:

Steps:

(1):- Open the new terminal and clone the git repository

git clone https://github.com/rojarfast1991/TestGit.git

(2) Automatic git login prompt will open and it will be asked you to enter a user credential.

UserName : - xxxxxxx

PassWord : - xxxxxxx

Finally, cloning will start...

git clone https://github.com/rojarfast1991/TestGit.git

In my windows machine, I solved this by adding the below code snippet in rules object of .eslintrc.js file present in my current project's directory.

    "prettier/prettier": [
      "error",
      {
        "endOfLine": "auto"
      },
    ],

This worked on my Mac as well

Pass an empty array as the second argument to useEffect. This effectively tells React, quoting the docs:

This tells React that your effect doesn’t depend on any values from props or state, so it never needs to re-run.

Here's a snippet which you can run to show that it works:

function App() {_x000D_
  const [user, setUser] = React.useState(null);_x000D_
_x000D_
  React.useEffect(() => {_x000D_
    fetch('https://randomuser.me/api/')_x000D_
      .then(results => results.json())_x000D_
      .then(data => {_x000D_
        setUser(data.results[0]);_x000D_
      });_x000D_
  }, []); // Pass empty array to only run once on mount._x000D_
  _x000D_
  return <div>_x000D_
    {user ? user.name.first : 'Loading...'}_x000D_
  </div>;_x000D_
}_x000D_
_x000D_
ReactDOM.render(<App/>, document.getElementById('app'));

<script src="https://unpkg.com/[email protected]/umd/react.development.js"></script>_x000D_

I'm using yarn. I had to do the following to overcome the error.

yarn add @babel/plugin-proposal-class-properties --dev

I had a problem like this before, it was the gradle.properties file doesn't exist, only the gradle.properties.txt , so i went to my project folder and i copied & pasted the gradle.properties.txt file but without .txt extension then it finally worked.

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.

Upgrading pip in windows with -

python -m pip install --upgrade pip

and then running pip install with --user option -

pip install --user package_name

solved my problem.

it is due to incompatibility.

please upgrade classpath("com.android.tools.build:gradle:4.0.1") in build.gradle file under android folder.

For spring boot version 2.X.X below configuration worked for me.

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

Old jdbc driver is deprecated. The new one is mentioned on above configuration. Please use the same and restart the project.

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)]

When you adding assets directory in pubspec.yaml file give more attention in to spaces

this is wrong

flutter:
   assets:
    - assets/images/lake.jpg

This is the correct way,

flutter:
  assets:
    - assets/images/

You are having issue with newly MySQL version that came with "caching_sha2_password" plugin, follow the below command to get it resolved.

DROP USER 'your_user_name'@'%';
CREATE USER 'your_user_name'@'%' IDENTIFIED WITH mysql_native_password BY 'your_user_password';
GRANT ALL PRIVILEGES ON your_db_name.* TO 'your_user_name'@'%' identified by 'your_user_password';

Or you can just use the below command to keep your privileges as it is:

ALTER USER your_user_name IDENTIFIED WITH mysql_native_password;

Faced the same error. In my case , what i did wrong was that i injected the service(named DataService in my case) inside the constructor within the Component but I simply forgot to import it within the component.

 constructor(private dataService:DataService ) {
    console.log("constructor called");
  }

I missed the below import code.

import { DataService } from '../../services/data.service';

check out this page from flutter wiki :

Creating Responsive Apps

Use the LayoutBuilder class: From its builder property, you get a BoxConstraints. Examine the constraint's properties to decide what to display. For example, if your maxWidth is greater than your width breakpoint, return a Scaffold object with a row that has a list on the left. If it's narrower, return a Scaffold object with a drawer containing that list. You can also adjust your display based on the device's height, the aspect ratio, or some other property. When the constraints change (e.g. the user rotates the phone, or puts your app into a tile UI in Nougat), the build function will rerun.

You must use some of the C # conversion systems:

string to boolean: True to true

string str = "True";
bool mybool = System.Convert.ToBoolean(str);

boolean to string: true to True

bool mybool = true;
string str = System.Convert.ToString(mybool);

//or

string str = mybool.ToString();

bool.Parse expects one parameter which in this case is str, even .

Convert.ToBoolean expects one parameter.

bool.TryParse expects two parameters, one entry (str) and one out (result).

If TryParse is true, then the conversion was correct, otherwise an error occurred

string str = "True";
bool MyBool = bool.Parse(str);

//Or

string str = "True";
if(bool.TryParse(str, out bool result))
{
   //Correct conversion
}
else
{
     //Incorrect, an error has occurred
}

@Bhabadyuti Bal give us a good answer, in gradle you can use :

compile 'org.springframework.boot:spring-boot-starter-data-jpa' 
compile 'com.h2database:h2'

in test time :

testCompile 'org.reactivecommons.utils:object-mapper:0.1.0'
testCompile 'com.h2database:h2'

As this post gets a bit of popularity I edited it a bit. Spring Boot 2.x.x changed default JDBC connection pool from Tomcat to faster and better HikariCP. Here comes incompatibility, because HikariCP uses different property of jdbc url. There are two ways how to handle it:

OPTION ONE

There is very good explanation and workaround in spring docs:

Also, if you happen to have Hikari on the classpath, this basic setup does not work, because Hikari has no url property (but does have a jdbcUrl property). In that case, you must rewrite your configuration as follows:

app.datasource.jdbc-url=jdbc:mysql://localhost/test
app.datasource.username=dbuser
app.datasource.password=dbpass

OPTION TWO

There is also how-to in the docs how to get it working from "both worlds". It would look like below. ConfigurationProperties bean would do "conversion" for jdbcUrl from app.datasource.url

@Configuration
public class DatabaseConfig {
    @Bean
    @ConfigurationProperties("app.datasource")
    public DataSourceProperties dataSourceProperties() {
        return new DataSourceProperties();
    }

    @Bean
    @ConfigurationProperties("app.datasource")
    public HikariDataSource dataSource(DataSourceProperties properties) {
        return properties.initializeDataSourceBuilder().type(HikariDataSource.class)
                .build();
    }
}

You need to set JDK 1.5 to your project and also all dependent project or jar file should also compiled with JDK 1.5

If you have a standard code signing certificate, some time will be needed for your application to build trust. Microsoft affirms that an Extended Validation (EV) Code Signing Certificate allows us to skip this period of trust-building. According to Microsoft, extended validation certificates allow the developer to immediately establish a reputation with SmartScreen. Otherwise, the users will see a warning like "Windows Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk.", with the two buttons: "Run anyway" and "Don't run".

Another Microsoft resource states the following (quote): "Although not required, programs signed by an EV code signing certificate can immediately establish a reputation with SmartScreen reputation services even if no prior reputation exists for that file or publisher. EV code signing certificates also have a unique identifier which makes it easier to maintain reputation across certificate renewals."

My experience is as follows. Since 2005, we have been using regular (non-EV) code signing certificates to sign .MSI, .EXE and .DLL files with time stamps, and there has never been a problem with SmartScreen until 2018, when there was just one case when it took 3 days for a beta version of our application to build trust since we have released it to beta testers, and it was in the middle of certificate validity period. I don't know what SmartScreen might not like in that specific version of our application, but there have been no SmartScreen complaints since then. Therefore, if your certificate is a non-EV, it is a signed application (such as an .MSI file) that will build trust over time, not a certificate. For example, a certificate can be issued a few months ago and used to sign many files, but for each signed file you publish, it may take a few days for SmartScreen to stop complaining about the file after publishing, as was in our case in 2018.

As a conclusion, to avoid the warning completely, i.e. prevent it from happening even suddenly, you need an Extended Validation (EV) code signing certificate.

I added file called .prettierrc in my project folder. File content:

{
    "singleQuote": true,
    "vetur.format.defaultFormatterOptions": {
        "prettier": {
            "singleQuote": true
        }
    }
}

i solved it, try: click on open sdk settings and open flutter and then add sdk location when your download

Thanks for the great answers! Fastest way to get a few one-off files to Colab from Google drive: Load the Drive helper and mount

from google.colab import drive

This will prompt for authorization.

drive.mount('/content/drive')

Open the link in a new tab-> you will get a code - copy that back into the prompt you now have access to google drive check:

!ls "/content/drive/My Drive"

then copy file(s) as needed:

!cp "/content/drive/My Drive/xy.py" "xy.py"

confirm that files were copied:

!ls

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

Probably you showing Activity looking like Dialog(non-fullscreen), so remove screenOrientation from Manifest or from code. This will fix the issue.

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

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

EDIT

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

try this :

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"
defaultConfig {

        targetSdkVersion 26
    }

}


compile 'com.android.support:appcompat-v7:25.1.0'

It has worked for me

For me this problem occurred because I had a some invalid character in my Groovy script. In our case this was an extra blank line after the closing bracket of the script.

This command did the trick from @Aniket Sinha's answer above:

pip install mysqlclient

Usually /deep/ “shadow-piercing” combinator can be used to force a style down to child components. This selector had an alias >>> and now has another one called ::ng-deep.

since /deep/ combinator has been deprecated, it is recommended to use ::ng-deep

For example:

<div class="overview tab-pane" id="overview" role="tabpanel" [innerHTML]="project?.getContent( 'DETAILS')"></div>

and css

.overview {
    ::ng-deep {
        p {
            &:last-child {
                margin-bottom: 0;
            }
        }
    }
}

it will be applied to child components

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

Or exports the following option on your terminal:

Linux/MAC:

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

Windows:

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

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

Linux:

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

Windows:

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

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

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

Spring Boot 2.2.2 / Gradle:

Gradle (build.gradle):

Code:

ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JavaTimeModule());
User user = mapper.readValue(json, User.class);

To support IE11 with auto-placement, I converted grid to table layout every time I used the grid layout in 1 dimension only. I also used margin instead of grid-gap.

The result is the same, see how you can do it here https://jsfiddle.net/hp95z6v1/3/

Some version working

<div class="visible-xs">Only Mobile visible</div>

From personal experience, it is always a best, first step to run your site in Incognito (Chrome), Private Browsing (Firefox), and InPrivate (IE11 && Edge) to remove the interference of add-ons/extensions. These can still interfere with testing in this mode if they are enabled explicitly in their settings. However, it is an easy first step to troubleshooting an issue.

The reason I am here, was due to Web of Trust (WoT) adding content to my page, and my page having had very strict Content Security Policy:

Header set Content-Security-Policy "default-src 'none'; font-src 'self' data:; style-src 'self' 'unsafe-inline' data:; img-src 'self' data:; script-src 'self' 'unsafe-inline'; connect-src 'self';"

This caused many errors. I was looking more for an answer on how to tell the extension to not try and run on this site programatically. This way when people have extensions, they just won't run on my site. I imagine if this were possible, ad blockers would have been banned on sites long ago. So my research is a bit naive. Hope this helps anyone else trying to diagnose an issue that is not specifically tied to the handful of mentioned extensions in other answers.

The MaterialModule was deprecated in the beta3 version with the goal that developers should only import into their applications what they are going to use and thus improve the bundle size.

The developers have now 2 options:

• Create a custom MyMaterialModule which imports/exports the components that your application requires and can be imported by other (feature) modules in your application.
• Import directly the individual material modules that a module requires into it.

Take the following as example (extracted from material page)

First approach:

import {MdButtonModule, MdCheckboxModule} from '@angular/material';

@NgModule({
  imports: [MdButtonModule, MdCheckboxModule],
  exports: [MdButtonModule, MdCheckboxModule],
})
export class MyOwnCustomMaterialModule { }

Then you can import this module into any of yours.

Second approach:

import {MdButtonModule, MdCheckboxModule} from '@angular/material';

@NgModule({
  ...
  imports: [MdButtonModule, MdCheckboxModule],
  ...
})
export class PizzaPartyAppModule { }

Now you can use the respective material components in all the components declared in PizzaPartyAppModule

It is worth mentioning the following:

• With the latest version of material, you need to import BrowserAnimationsModule into your main module if you want the animations to work
• With the latest version developers now need to add @angular/cdk to their package.json (material dependency)
• Import the material modules always after BrowserModule, as stated by the docs:

Whichever approach you use, be sure to import the Angular Material modules after Angular's BrowserModule, as the import order matters for NgModules.

This exception says that you are trying to deserialize the object "Address" from string "\"\"" instead of an object description like "{…}". The deserializer can't find a constructor of Address with String argument. You have to replace "" by {} to avoid this error.

You can also move mounted out of the Vue instance and make it a function in the top-level scope. This is also a useful trick for server side rendering in Vue.

function init() {
  // Use `this` normally
}

new Vue({
  methods:{
    init
  },
  mounted(){
    init.call(this)
  }
})

This is my personal approach.

class ColorType {
    static get RED () {
        return "red";
    }

    static get GREEN () {
        return "green";
    }

    static get BLUE () {
        return "blue";
    }
}

// Use case.
const color = Color.create(ColorType.RED);

Check all the projects are loaded. In my case one of the project was unloaded and reloading the project clears the errors.

What worked here : on the client

1) ssh-add

2) ssh-copy-id user@server

The keys has been created some time ago with plain "ssh-keygen -t rsa" I sw the error message because I copied across my ssh public key from client to server (with ssh-id-copy) without running ssh-add first, since I erroneously assumed I'd added them some time earlier.

Scenario:

1. Windows 10 with Visual Studio 2017 (FRESH installation).

2. 'C' project (ERROR like -> cannot open source file: 'stdio.h', 'windows.h', etc.).

Resolve:

1. Run 'Visual Studio Installer'.

2. Click button 'Modify'.

3. Select 'Desktop development with C++'.

4. From "Installation details"(usually on the right-sidebar) select:

   4.1. Windows 10 SDK(10.0.17134.0).

   • Version of SDK in 4.1. is just for example.

5. Click button 'Modify', to apply changes.

6. Right-click 'SomeProject' -> 'Properties'.
7. 'Configuration:' -> 'All Configurations' and 'Platform:' -> 'All Platforms'.
8. 'Configuration Properties' -> 'General' -> 'Windows SDK Version':
   • change(select from combobox) SDK version to currently installed;
9. Click button 'Apply', to apply changes.

val is immutable, final, the first assigned value cannot be changed.

val name:String = "andy"

name = "thomas" //Error: Val cannot be reassigned

var is mutable, reassignable, you can change the value over and over.

val a:Int = 1
var b:Int = 1
println("${a + b}") // output 2

b = 4
println("${a + b}") // output 5

I think the easiest way to remember it :

val = variable final

var = variable reassignable, or the opposite of val.

Kotlin Coroutines (Clear & Concise)

AsyncTask is really clunky. Coroutines are a cleaner alternative (just sprinkle a couple of keywords and your sync code becomes async).

// Step 1: add `suspend` to your fun
suspend fun roomFun(...): Int
suspend fun notRoomFun(...) = withContext(Dispatchers.IO) { ... }

// Step 2: launch from coroutine scope
private fun myFun() {
    lifecycleScope.launch { // coroutine on Main
        val queryResult = roomFun(...) // coroutine on IO
        doStuff() // ...back on Main
    }
}

Dependencies (adds coroutine scopes for arch components):

// lifecycleScope:
implementation 'androidx.lifecycle:lifecycle-runtime-ktx:2.2.0-alpha04'

// viewModelScope:
implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.2.0-alpha04'

-- Updates:
08-May-2019: Room 2.1 now supports suspend
13-Sep-2019: Updated to use Architecture components scope

Basically it's OK to store your JWT in your localStorage.

And I think this is a good way. If we are talking about XSS, XSS using CDN, it's also a potential risk of getting your client's login/pass as well. Storing data in local storage will prevent CSRF attacks at least.

You need to be aware of both and choose what you want. Both attacks it's not all you are need to be aware of, just remember: YOUR ENTIRE APP IS ONLY AS SECURE AS THE LEAST SECURE POINT OF YOUR APP.

Once again storing is OK, be vulnerable to XSS, CSRF,... isn't

Remember to pipe Observables to async, like *ngFor item of items$ | async, where you are trying to *ngFor item of items$ where items$ is obviously an Observable because you notated it with the $ similar to items$: Observable<IValuePair>, and your assignment may be something like this.items$ = this.someDataService.someMethod<IValuePair>() which returns an Observable of type T.

Adding to this... I believe I have used notation like *ngFor item of (items$ | async)?.someProperty

I tried use [disabled]="!editmode" but it not work in my case.

This is my solution [disabled]="!editmode ? 'disabled': null" , I share for whom concern.

<button [disabled]="!editmode ? 'disabled': null" 
    (click)='loadChart()'>
            <div class="btn-primary">Load Chart</div>
    </button>

This method does not need to modify dtype or ravel your numpy array.

The core idea is: 1.initialize with one extra row. 2.change the list(which has one more row) to array 3.delete the extra row in the result array e.g.

>>> a = [np.zeros((10,224)), np.zeros((10,))]
>>> np.array(a)
# this will raise error,
ValueError: could not broadcast input array from shape (10,224) into shape (10)

# but below method works
>>> a = [np.zeros((11,224)), np.zeros((10,))]
>>> b = np.array(a)
>>> b[0] = np.delete(b[0],0,0)
>>> print(b.shape,b[0].shape,b[1].shape)
# print result:(2,) (10,224) (10,)

Indeed, it's not necessarily to add one more row, as long as you can escape from the gap stated in @aravk33 and @user707650 's answer and delete the extra item later, it will be fine.

You can't do it. Interfaces don't exist at runtime (like @basarat said).

Now, I am working with following:

const IMyTable_id = 'id';
const IMyTable_title = 'title';
const IMyTable_createdAt = 'createdAt';
const IMyTable_isDeleted = 'isDeleted';

export const IMyTable_keys = [
  IMyTable_id,
  IMyTable_title,
  IMyTable_createdAt,
  IMyTable_isDeleted,
];

export interface IMyTable {
  [IMyTable_id]: number;
  [IMyTable_title]: string;
  [IMyTable_createdAt]: Date;
  [IMyTable_isDeleted]: boolean;
}

The following code worked for me:

echo userInput

I used this solution.

If you have a nested state like this:

this.state = {
  formInputs:{
    friendName:{
      value:'',
      isValid:false,
      errorMsg:''
    },
    friendEmail:{
      value:'',
      isValid:false,
      errorMsg:''
    }
  }
}

you can declare the handleChange function that copy current status and re-assigns it with changed values

handleChange(el) {
    let inputName = el.target.name;
    let inputValue = el.target.value;

    let statusCopy = Object.assign({}, this.state);
    statusCopy.formInputs[inputName].value = inputValue;

    this.setState(statusCopy);
  }

here the html with the event listener. Make sure to use the same name used into state object (in this case 'friendName')

<input type="text" onChange={this.handleChange} " name="friendName" />

You need to add the tomcat dependency in your pom

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>

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.

For Windows 7 and above go to C:\Users\USERNAME\.android folder and follow below steps:

1. Right click > create a new txt file with name repositories.txt
2. Open the file and go to File > Save As.. > select Save as type: All Files
3. Rename repositories.txt to repositories.cfg

The previous answer is pretty good, but I also wanted to mention that there is a fixed layout equivalent for grids, you just need to write minmax(0, 1fr) instead of 1fr as your track size.

I have got this error when trying to create JPA entity with the name "User" (in Postgres) that is reserved. So the way it is resolved is to change the table name by @Table annotation:

@Entity
@Table(name="users")
public class User {..}

Or change the table name manually.

Problem solved, I've not added the index.html. Which is point out in the web.xml

Note: a project may have more than one web.xml file.

if there are another web.xml in

src/main/webapp/WEB-INF

Then you might need to add another index (this time index.jsp) to

src/main/webapp/WEB-INF/pages/

Update Android Studio and Gradle. Changing the respective updated gradle version in build.gradle file worked for me.

If you are using formik in your project it has some easy way to handle this stuff. Here is the most easiest way to do with formik.

First set your initial values inside the formik initivalues attribute or in the react. state

Here, the initial values is define in react state

   state = { 
     data: {
        fy: {
            active: "N"
        }
     }
   }

define above initialValues for formik field inside formik initiValues attribute

<Formik
 initialValues={this.state.data}
 onSubmit={(values, actions)=> {...your actions goes here}}
>
{({ isSubmitting }) => (
  <Form>
    <Field type="checkbox" name="fy.active" onChange={(e) => {
      const value = e.target.checked;
      if(value) setFieldValue('fy.active', 'Y')
      else setFieldValue('fy.active', 'N')
    }}/>
  </Form>
)}
</Formik>

Make a console to the check the state updated into string instead of booleanthe formik setFieldValue function to set the state or go with react debugger tool to see the changes iniside formik state values.

On the console, looking at the topmost right side of the dialog you should see a red button kinda like a buzzer. To stop the spring boot application properly you just ran, go ahead and hit this particular "red" button and your problem is solved. Hope this helps!

For anyone where none of these solutions are working, make sure that your request origin equals your request target, see this github issue.

I short, if you visit your website on 127.0.0.1:8000, then make sure that the requests you send are targeting your server on 127.0.0.1:8001 and not localhost:8001, although it might be the same target theoretically.

Solved the problem by re-installing CUDA:

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/cuda-ubuntu1804.pin
mv cuda-ubuntu1804.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget https://developer.download.nvidia.com/compute/cuda/11.1.0/local_installers/cuda-repo-ubuntu1804-11-1-local_11.1.0-455.23.05-1_amd64.deb
echo "md5sum: $(md5sum cuda-repo-ubuntu1804-11-1-local_11.1.0-455.23.05-1_amd64.deb)"
echo "correct: 056de5e03444cce506202f50967b0016"
dpkg -i cuda-repo-ubuntu1804-11-1-local_11.1.0-455.23.05-1_amd64.deb
apt-key add /var/cuda-repo-ubuntu1804-11-1-local/7fa2af80.pub
apt-get -qq update
apt-get -qq -y install cuda
rm cuda-repo-ubuntu1804-11-1-local_11.1.0-455.23.05-1_amd64.deb

I had two methods: in the <script>, goes to show, that you can spend hours looking for something that was such a simple mistake.

In order to spring to create bean and inject it class should be marked with @Componet,@service,@Repository etc in your context it should be

package main.java.service;

import java.util.List;
import main.java.model.User;
import org.springframework.data.mongodb.repository.MongoRepository;
@Repository
public interface UserService extends MongoRepository<User, String> {
    public List<User> findAll();
}

You're doing a few things wrong.

1. First, browserHistory isn't a thing in V4, so you can remove that.

2. Second, you're importing everything from react-router, it should be react-router-dom.

3. Third, react-router-dom doesn't export a Router, instead, it exports a BrowserRouter so you need to import { BrowserRouter as Router } from 'react-router-dom.

Looks like you just took your V3 app and expected it to work with v4, which isn't a great idea.

In previous posts I have read that this feature IS available on VS 2015 community if you FIRST install SQL Server express (free) and THEN install VS. I have tried it and it worked. I just had to reinstall Windows and am going thru the same procedure now and it did not work... so will try again :). I know it worked 6 months ago when I tried.

-Ed

in HTML:

<a class="main-item" (click)="onNavigate()">Go to URL</a>

OR

<button class="main-item" (click)="onNavigate()">Go to URL</button>

in TS file:

onNavigate(){
    // your logic here.... like set the url 
    const url = 'https://www.google.com';
    window.open(url, '_blank');
}

Ctrl+K, Ctrl+1 and then Ctrl+K, Ctrl+2 will do close to what you want.

The first command collapses level 1 (usually classes), and the second command collapses level 2 (usually methods).

You might even find it useful to skip the first command.

You can simply access the element classList which received the click event using event.target then by using toggle method on the classList object to add or remove the intended class

<div onClick={({target}) => target.classList.toggle('active')}>
  ....
  ....
  ....
</div>

Equevelent

<div onClick={e=> e.target.classList.toggle('active')}>
  ....
  ....
  ....
</div>

OR by declaring a function that handle the click and does extra work

function handleClick(el){
    .... Do more stuff
    el.classList.toggle('active');

}
<div onClick={({target})=> handleClick(target)}>
  ....
  ....
  ....
</div>

In my case, it was caused from an incompatibility with OpenJDK 9 (which I haven't investigated).

If you don't need JDK 9, a temporary work-around would be to purge it from your machine:

sudo apt-get remove --purge openjdk-9-jdk openjdk-9-jre 
sudo apt-get remove --purge openjdk-9-jdk-headless openjdk-9-jre-headless

This confusing me a bit too.

The problem is on "path" attribute in your xml file.

From this document FileProvider 'path' is a subdirectory, but in another document (camera/photobasics) shown 'path' is full path.

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="my_images" path="Android/data/com.example.package.name/files/Pictures" />
</paths>

I just change this 'path' to full path and it just work.

You can run using the following command. Here I want to run using spring profile local:

spring-boot:run -Drun.jvmArguments="-Dspring.profiles.active=local"

For the record, the spring.jpa.hibernate.ddl-auto property is Spring Data JPA specific and is their way to specify a value that will eventually be passed to Hibernate under the property it knows, hibernate.hbm2ddl.auto.

The values create, create-drop, validate, and update basically influence how the schema tool management will manipulate the database schema at startup.

For example, the update operation will query the JDBC driver's API to get the database metadata and then Hibernate compares the object model it creates based on reading your annotated classes or HBM XML mappings and will attempt to adjust the schema on-the-fly.

The update operation for example will attempt to add new columns, constraints, etc but will never remove a column or constraint that may have existed previously but no longer does as part of the object model from a prior run.

Typically in test case scenarios, you'll likely use create-drop so that you create your schema, your test case adds some mock data, you run your tests, and then during the test case cleanup, the schema objects are dropped, leaving an empty database.

In development, it's often common to see developers use update to automatically modify the schema to add new additions upon restart. But again understand, this does not remove a column or constraint that may exist from previous executions that is no longer necessary.

In production, it's often highly recommended you use none or simply don't specify this property. That is because it's common practice for DBAs to review migration scripts for database changes, particularly if your database is shared across multiple services and applications.

In webpack.config.js replace loaders: [..] with rules: [..] It worked for me.

If you used to calle a component like this:

Vue.component('dashboard', require('./components/Dashboard.vue'));

I suppose that problem occurred when you update to laravel mix 5.0 or another libraries, so you have to put .default. As like below:

Vue.component('dashboard', require('./components/Dashboard.vue').default);

I solved the same problem.

i am using my custom implementation in kotlin:

I see from your screenshot that you are using WSL on Windows. And, with Windows, comes virus scanners, and virus scanning can make NPM install very slow!

Adding an exemption or disabling virus scanning during install can greatly speed it up, but potentially this is undesirable given the possibility of malicious NPM packages

One link suggests triple install time https://ikriv.com/blog/?p=2174

I have not profiled extensively myself though

The problem for me was not got the port from process.env.PORT it is very important because Heroku and other services properly do a random port numbers to use.

So that is the code that work for me eventuly :

var app = require('express')();
var http = require('http').createServer(app);
const serverPort = process.env.PORT ; //<----- important 

const io = require('socket.io')(http,{
  cors: {
    origin: '*',
    methods: 'GET,PUT,POST,DELETE,OPTIONS'.split(','),
    credentials: true
  }
});

http.listen(serverPort,()=>{
  console.log(`server listening on port ${serverPort}`)
})

1-Delete the migration file. 2-connect to your database and drop the table created by the migration. 3-recreate the file of the migration with the the right sql.

There is another answer here that also fits the authors request: 'compile-time' way to get all property names defined interface

If you use the plugin ts-transformer-keys and an Interface to your class you can get all the keys for the class.

But if you're using Angular or React then in some scenarios there is additional configuration necessary (webpack and typescript) to get it working: https://github.com/kimamula/ts-transformer-keys/issues/4

Most probably you want to use a method

<span>{{ fullName('Hi') }}</span>

methods: {
  fullName(salut) {
      return `${salut} ${this.firstName} ${this.lastName}`
  }
}

Longer explanation

Technically you can use a computed property with a parameter like this:

computed: {
   fullName() {
      return salut => `${salut} ${this.firstName} ${this.lastName}`
   }
}

(Thanks Unirgy for the base code for this.)

The difference between a computed property and a method is that computed properties are cached and change only when their dependencies change. A method will evaluate every time it's called.

If you need parameters, there are usually no benefits of using a computed property function over a method in such a case. Though it allows you to have a parametrized getter function bound to the Vue instance, you lose caching so not really any gain there, in fact, you may break reactivity (AFAIU). You can read more about this in Vue documentation https://vuejs.org/v2/guide/computed.html#Computed-Caching-vs-Methods

The only useful situation is when you have to use a getter and need to have it parametrized. For instance, this situation happens in Vuex. In Vuex it's the only way to synchronously get parametrized result from the store (actions are async). Thus this approach is listed by official Vuex documentation for its getters https://vuex.vuejs.org/guide/getters.html#method-style-access

A really dumb answer (I'll vote myself down in a minute), but this worked for me:

After adding your pipe, if you're still getting the errors and are running your Angular site using "ng serve", stop it... then start it up again.

For me, none of the other suggestions worked, but simply stopping, then restarting "ng serve" was enough to make the error go away.

Strange.

Note that you can only read a stream once, so in some cases, you may need to clone the response in order to repeatedly read it:

fetch('example.json')
  .then(res=>res.clone().json())
  .then( json => console.log(json))

fetch('url_that_returns_text')
  .then(res=>res.clone().text())
  .then( text => console.log(text))

You can approach it from either an "allow list" or a "block list" way:

// Block list
// Remove the values you don't want
var result = _.omit(credentials, ['age']);

// Allow list
// Only allow certain values
var result = _.pick(credentials, ['fname', 'lname']);

If it's reusable business logic, you can partial it out as well:

// Partial out a "block list" version
var clean = _.partial(_.omit, _, ['age']);

// and later
var result = clean(credentials);

Note that Lodash 5 will drop support for omit

A similar approach can be achieved without Lodash:

const transform = (obj, predicate) => {
  return Object.keys(obj).reduce((memo, key) => {
    if(predicate(obj[key], key)) {
      memo[key] = obj[key]
    }
    return memo
  }, {})
}

const omit = (obj, items) => transform(obj, (value, key) => !items.includes(key))

const pick = (obj, items) => transform(obj, (value, key) => items.includes(key))

// Partials
// Lazy clean
const cleanL = (obj) => omit(obj, ['age'])

// Guarded clean
const cleanG = (obj) => pick(obj, ['fname', 'lname'])


// "App"
const credentials = {
    fname:"xyz",
    lname:"abc",
    age:23
}

const omitted = omit(credentials, ['age'])
const picked = pick(credentials, ['age'])
const cleanedL = cleanL(credentials)
const cleanedG = cleanG(credentials)

The date time you're passing is not a iso local date time format.

Change to

@Column(name = "start_date")
@DateTimeFormat(iso = DateTimeFormatter.ISO_LOCAL_DATE_TIME)
@JsonFormat(pattern = "YYYY-MM-dd HH:mm")
private LocalDateTime startDate;

and pass date string in the format '2011-12-03T10:15:30'.

But if you still want to pass your custom format, use just have to specify the right formatter.

Change to

@Column(name = "start_date")
@DateTimeFormat(iso = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm"))
@JsonFormat(pattern = "YYYY-MM-dd HH:mm")
private LocalDateTime startDate;

I think your problem is the @DateTimeFormat has no effect at all. As the jackson is doing the deseralization and it doesnt know anything about spring annotation and I dont see spring scanning this annotation in the deserialization context.

Alternatively, you can try setting the formatter while registering the java time module.

LocalDateTimeDeserializer localDateTimeDeserializer = new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm"));
module.addDeserializer(LocalDateTime.class, localDateTimeDeserializer);

Here is the test case with the deseralizer which works fine. May be try to get rid of that DateTimeFormat annotation altogether.

@RunWith(JUnit4.class)
public class JacksonLocalDateTimeTest {

    private ObjectMapper objectMapper;

    @Before
    public void init() {
        JavaTimeModule module = new JavaTimeModule();
        LocalDateTimeDeserializer localDateTimeDeserializer =  new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm"));
        module.addDeserializer(LocalDateTime.class, localDateTimeDeserializer);
        objectMapper = Jackson2ObjectMapperBuilder.json()
                .modules(module)
                .featuresToDisable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)
                .build();
    }

    @Test
    public void test() throws IOException {
        final String json = "{ \"date\": \"2016-11-08 12:00\" }";
        final JsonType instance = objectMapper.readValue(json, JsonType.class);

        assertEquals(LocalDateTime.parse("2016-11-08 12:00",DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm") ), instance.getDate());
    }
}


class JsonType {
    private LocalDateTime date;

    public LocalDateTime getDate() {
        return date;
    }

    public void setDate(LocalDateTime date) {
        this.date = date;
    }
}

The fix was at the accepted answer. Yet if someone wants to know why it worked and why the implementation in the SO question didn't work,

First, functions are first class objects in JavaScript. That means they are treated like any other variable. Function can be passed as an argument to other functions, can be returned by another function and can be assigned as a value to a variable. Read more here.

So we use that variable to invoke the function by adding parentheses () at the end.

One thing, If you have a function that returns a funtion and you just need to call that returned function, you can just have double paranthesis when you call the outer function ()().

Use align-items: flex-start on the container, or align-self: flex-start on the flex items.

No need for display: inline-flex.

An initial setting of a flex container is align-items: stretch. This means that flex items will expand to cover the full length of the container along the cross axis.

The align-self property does the same thing as align-items, except that align-self applies to flex items while align-items applies to the flex container.

By default, align-self inherits the value of align-items.

Since your container is flex-direction: column, the cross axis is horizontal, and align-items: stretch is expanding the child element's width as much as it can.

You can override the default with align-items: flex-start on the container (which is inherited by all flex items) or align-self: flex-start on the item (which is confined to the single item).

Learn more about flex alignment along the cross axis here:

• How does flex-wrap work with align-self, align-items and align-content?

Learn more about flex alignment along the main axis here:

• In CSS Flexbox, why are there no "justify-items" and "justify-self" properties?

In my case, deleting any of the below annotations cause the error message 'entityManagerFactory' to show, for example.

 @Id
  @GeneratedValue(strategy=GenerationType.AUTO)

or

@ManyToMany(targetEntity=listOfObject_x.class)

The error message disappears after adding the missing annotation(s).

package mypackage_unameit;
import javax.persistence.PrePersist;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

import lombok.Data;

@Data
@Entity
public class Someclasss {

  @Id
  @GeneratedValue(strategy=GenerationType.AUTO)
  private Long id;

  @NotNull
  @Size(min=5, message="Name must be at least 5 characters long")
  private String name;

  private Date createdAt;

  @ManyToMany(targetEntity=listOfObject_x.class)
  @Size(min=1, message="You must choose at least 1 ingredient")
  private List<listOfObject_x>   = new ArrayList<>();

  @PrePersist
  void createdAt() {
    this.createdAt = new Date();
  }
}

Set -Dspring.profiles.active=local under program arguments.

A delarative way to do that (In fact, a minor tweek to @Compito's original answer):

1. Set spring.profiles.active=test in test/resources/application-default.properties.
2. Add test/resources/application-test.properties for tests and override only the properties you need.

Using this.props.children is the idiomatic way to pass instantiated components to a react component

const Label = props => <span>{props.children}</span>
const Tab = props => <div>{props.children}</div>
const Page = () => <Tab><Label>Foo</Label></Tab>

When you pass a component as a parameter directly, you pass it uninstantiated and instantiate it by retrieving it from the props. This is an idiomatic way of passing down component classes which will then be instantiated by the components down the tree (e.g. if a component uses custom styles on a tag, but it wants to let the consumer choose whether that tag is a div or span):

const Label = props => <span>{props.children}</span>
const Button = props => {
    const Inner = props.inner; // Note: variable name _must_ start with a capital letter 
    return <button><Inner>Foo</Inner></button>
}
const Page = () => <Button inner={Label}/>

If what you want to do is to pass a children-like parameter as a prop, you can do that:

const Label = props => <span>{props.content}</span>
const Tab = props => <div>{props.content}</div>
const Page = () => <Tab content={<Label content='Foo' />} />

After all, properties in React are just regular JavaScript object properties and can hold any value - be it a string, function or a complex object.

I had the same issue and I solved by adding an empty class annotated with SpringBootApplication in the root package of the folder src/test/java

package org.enricogiurin.core;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class CoreTestConfiguration {}

To read the values from application.properties we need to just annotate our main class with @SpringBootApplication and the class where you are reading with @Component or variety of it. Below is the sample where I have read the values from application.properties and it is working fine when web service is invoked. If you deploy the same code as is and try to access from http://localhost:8080/hello you will get the value you have stored in application.properties for the key message.

package com.example;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class DemoApplication {

    @Value("${message}")
    private String message;

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @RequestMapping("/hello")
    String home() {
        return message;
    }

}

Try and let me know

UPDATE: This is no longer valid for newer Keras versions. Please use argmax() as in the answer from Emilia Apostolova.

The functional API models have just the predict() function which for classification would return the class probabilities. You can then select the most probable classes using the probas_to_classes() utility function. Example:

y_proba = model.predict(x)
y_classes = keras.np_utils.probas_to_classes(y_proba)

This is equivalent to model.predict_classes(x) on the Sequential model.

The reason for this is that the functional API support more general class of tasks where predict_classes() would not make sense.

Thanks for the reply. I was using "mvn clean install" in the maven build configuration. we no need to use "mvn" command if running through eclipse.

After buiding the application using the command "clean install" , I got one more error -
"No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?"

I followed this link:- No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

now application building is fine in eclipse.

I myself am trying to see how can I update RC4 to RC5 and thus I stumbled upon this entry and new approach to dynamic component creation still holds a bit of mystery to me, so I wont suggest anything on component factory resolver.

But, what I can suggest is a bit clearer approach to component creation on this scenario - just use switch in template that would create string editor or text editor according to some condition, like this:

<form [ngSwitch]="useTextarea">
    <string-editor *ngSwitchCase="false" propertyName="'code'" 
                 [entity]="entity"></string-editor>
    <text-editor *ngSwitchCase="true" propertyName="'code'" 
                 [entity]="entity"></text-editor>
</form>

And by the way, "[" in [prop] expression have a meaning, this indicates one way data binding, hence you can and even should omit those in case if you know that you do not need to bind property to variable.

I faced same issue & it resolved by

ENTRYPOINT ["sh", "/docker-entrypoint.sh"]

For the Dockerfile in the original question it should be like:

ENTRYPOINT ["sh", "/usr/src/app/docker-entrypoint.sh"]

None of the solutions above worked for me straight away. So I followed these steps:

1. Add in pom.xml:

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

2. Go to Project Properties > Java Build Path, then remove the JRE System Library pointing to JRE1.5.

3. Force updated the project.

Let’s assume, your old app.module.ts may look similar to this :

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';

@NgModule({
    imports: [ BrowserModule ],
    declarations: [ AppComponent ],
    bootstrap: [ AppComponent ]
})

export class AppModule { }

Now import FormsModule in your app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';

@NgModule({
    imports: [ BrowserModule, FormsModule ],
    declarations: [ AppComponent ],
    bootstrap: [ AppComponent ]
})

export class AppModule { }

In the your first journey in spring boot project I recommend you to start with Spring Starter Try this link here.

It will auto generate the project structure for you like this.application.perperties it will be under /resources.

application.properties important change,

server.port = Your PORT(XXXX) by default=8080
server.servlet.context-path=/api (SpringBoot version 2.x.)
server.contextPath-path=/api (SpringBoot version < 2.x.)

Any way you can use application.yml in case you don't want to make redundancy properties setting.

Example
application.yml

server:
   port: 8080 
   contextPath: /api

application.properties

server.port = 8080
server.contextPath = /api

Just another solution in one line of Modern JS with no external libraries.

I was playing with "Destructuring" feature :

const raw = {_x000D_
    item1: { key: 'sdfd', value: 'sdfd' },_x000D_
    item2: { key: 'sdfd', value: 'sdfd' },_x000D_
    item3: { key: 'sdfd', value: 'sdfd' }_x000D_
  };_x000D_
var myNewRaw = (({ item1, item3}) => ({ item1, item3 }))(raw);_x000D_
console.log(myNewRaw);

Spring-boot framework allows us to provide YAML files as a replacement for the .properties file and it is convenient.The keys in property files can be provided in YAML format in application.yml file in the resource folder and spring-boot will automatically take it up.Keep in mind that the yaml format has to keep the spaces correct for the value to be read correctly.

You can use the @Value("${property}") to inject the values from the YAML files. Also Spring.active.profiles can be given to differentiate between different YAML for different environments for convenient deployment.

For testing purposes, the test YAML file can be named like application-test.yml and placed in the resource folder of the test directory.

If you are specifying the application-test.yml and provide the spring test profile in the .yml, then you can use the @ActiveProfiles('test') annotation to direct spring to take the configurations from the application-test.yml that you have specified.

@RunWith(SpringRunner.class)
@SpringBootTest(classes = ApplicationTest.class)
@ActiveProfiles("test")
public class MyTest {
 ...
}

If you are using JUnit 5 then no need for other annotations as @SpringBootTest already include the springrunner annotation. Keeping a separate main ApplicationTest.class enables us to provide separate configuration classes for tests and we can prevent the default configuration beans from loading by excluding them from a component scan in the test main class. You can also provide the profile to be loaded there.

@SpringBootApplication(exclude=SecurityAutoConfiguration.class)
public class ApplicationTest {
 
    public static void main(String[] args) {
        SpringApplication.run(ApplicationTest.class, args);
    }
}

Here is the link for Spring documentation regarding the use of YAML instead of .properties file(s): https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html

It seems that the problem is in eslint-plugin-react.

It can not correctly detect what props were mentioned in propTypes if you have annotated named objects via destructuring anywhere in the class.

There was similar problem in the past

If you provide your JVM the Spring profile there should be no problems:

java -Dspring.profiles.active=development -jar yourApplication.jar 

Also see Spring-Documentation:

http://docs.spring.io/spring-boot/docs/current/reference/html/howto-properties-and-configuration.html

69.5 Set the active Spring profiles

The Spring Environment has an API for this, but normally you would set a System property (spring.profiles.active) or an OS environment variable (SPRING_PROFILES_ACTIVE). E.g. launch your application with a -D argument (remember to put it before the main class or jar archive):

$ java -jar -Dspring.profiles.active=production demo-0.0.1-SNAPSHOT.jar

In Spring Boot you can also set the active profile in application.properties, e.g.

spring.profiles.active=production

A value set this way is replaced by the System property or environment variable setting, but not by the SpringApplicationBuilder.profiles() method. Thus the latter Java API can be used to augment the profiles without changing the defaults.

See Chapter 25, Profiles in the ‘Spring Boot features’ section for more information.

I have created following class

ConfigUtility.java

@Configuration
public class ConfigUtility {

    @Autowired
    private Environment env;

    public String getProperty(String pPropertyKey) {
        return env.getProperty(pPropertyKey);
    }
} 

and called as follow to get application.properties value

myclass.java

@Autowired
private ConfigUtility configUtil;

public AppResponse getDetails() {

  AppResponse response = new AppResponse();
    String email = configUtil.getProperty("emailid");
    return response;        
}

application.properties

[email protected]

unit tested, working as expected...

These are the steps I followed and it solved the problem

1)Upgraded my Power shell from version 2 to 3

2)Closed the PM Console

3)Restarted Visual Studio

4)Ran the below command in PM Console dotnet restore

5)Add-Migration InitialMigration

It worked !!!

For Linux, "ps aux | grep kafka" see if kafka properties are shown in the results. E.g. /path/to/kafka/server.properties

My error is caused by a System.import('xxx.js') statment. After replacing it with import xxx from 'xxx.js', the error solved.

I think it is because require('xxx.scss') also caused a dynamic import.

For the case in the question description, in my opinion, dynamic imports is not necessary, so the problem should be solved by just replacing all requires with import ... from ....

For some case which dynamic imports are necessary, you may need @babel/plugin-syntax-dynamic-import as other answers in this question.

I saw the same error when the scope of the jackson-databind dependency had been set to test:

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.9.9</version>
    <scope>test</scope>
</dependency>

Removing the <scope> line fixed the issue.

I achieved satisfying results with:

min-height: 100%;
min-width: 100%;

this way you always maintain the aspect ratio.

The complete css for an image that will replace "object-fit: cover;":

width: auto;
height: auto;
min-width: 100%;
min-height: 100%;
position: absolute;
right: 50%;
transform: translate(50%, 0);

It is important to remember that the driver(file) must have execution permission (linux chmod +x geckodriver).

To sum up:

1. Download gecko driver
2. Add execution permission

3. Add system property:

   System.setProperty("webdriver.gecko.driver", "FILE PATH");

4. Instantiate and use the class

   WebDriver driver = new FirefoxDriver();

5. Do whatever you want

6. Close the driver

   driver.close;

First of all, with the solution below, is necessary to understand that always the spring boot will read the application.properties file. So the other's profile files only will complement and replace the properties defined before.

Considering the follow files:

application.properties
application-qa.properties
application-prod.properties

1) Very important. The application.properties, and just this file, must have the follow line:

[email protected]@

2) Change what you want in the QA and PROD configuration files to see the difference between the environments.

3) By command line, start the spring boot app with any of this options:

It will start the app with the default application.properties file:

mvn spring-boot:run

It will load the default application.properties file and after the application-qa.properties file, replacing and/or complementing the default configuration:

mvn spring-boot:run -Dspring.profiles.active=qa

The same here but with the production environment instead of QA:

mvn spring-boot:run -Dspring.profiles.active=prod

Who ever also stumbles over this post.

I belive is the correct way:

  <div *ngFor="let appointment of (_nextFourAppointments | async).availabilities;"> 
    <div>{{ appointment }}</div>
  </div>

To be able to create a relation, the table Storage Engine must be InnoDB. You can edit in Operations tab.

Then, you need to be sure that the id column in your main table has been indexed. It should appear at Index section in Structure tab.

Finally, you could see the option Relations View in Structure tab. When edditing, you will be able to select the parent column in foreign table to create the relation.

See attachments. I hope this could be useful for anyone.

For everybody that falls off google, in here, this is the fix for VSCode 1.40 (2019):

Open the global settings.json: File > Preferences > Settings

Then select the tab 'User', open the section 'Extensions', click on 'C/C++'. Then scroll the right panel till you find a 'Edit in settings.json' button.

Last, you add the "C_Cpp.default.includePath" section. The code provided there is from my own system (Windows 7). You can use it as a base for your own libraries paths. (Remember to change the YOUR USERNAME to your correct system (my case windows) username)
(edit info: There is a problem with the recursion of my approach. VSCode doesn't like multiple definitions for the same thing. I solved it with "C_Cpp.intelliSenseEngine": "Tag Parser" )

the code before line 7, on the settings.json has nothing to do with arduino or includePath. You may not copy that...

JSON section to add to settings.json:

"C_Cpp.default.includePath": [
        "C:/Program Files (x86)/Arduino/libraries/**",
        "C:/Program Files (x86)/Arduino/hardware/arduino/avr/cores/arduino/**",
        "C:/Program Files (x86)/Arduino/hardware/tools/avr/avr/include/**",
        "C:/Program Files (x86)/Arduino/hardware/tools/avr/lib/gcc/avr/5.4.0/include/**",
        "C:/Program Files (x86)/Arduino/hardware/arduino/avr/variants/standard/**",
        "C:/Users/<YOUR USERNAME>/.platformio/packages/framework-arduinoavr/**",
        "C:/Users/<YOUR USERNAME>/Documents/Arduino/libraries/**",
        "{$workspaceFolder}/libraries/**",
        "{$workspaceFolder}/**"
    ],
"C_Cpp.intelliSenseEngine": "Tag Parser"

You can also get the value of an item in the jObject like this:

JToken value;
if (json.TryGetValue(key, out value))
{
   DoSomething(value);
}

Unfortunately, none of the mentioned solutions worked for me.

After trying out some of the answers from this issue, the following finally did work:

As one or more of the required iOS third-party libraries were not properly downloaded to ~/.rncache (meaning the files in there were corrupted and could not be unzipped), I removed the content of this folder, ran react-native run-ios again, and this eventually did the trick.

You can use Jasypt to encrypt properties, so you could have your property like this:

db.password=ENC(XcBjfjDDjxeyFBoaEPhG14wEzc6Ja+Xx+hNPrJyQT88=)

Jasypt allows you to encrypt your properties using different algorithms, once you get the encrypted property you put inside the ENC(...). For instance, you can encrypt this way through Jasypt using the terminal:

encrypted-pwd$ java -cp ~/.m2/repository/org/jasypt/jasypt/1.9.2/jasypt-1.9.2.jar  org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI input="contactspassword" password=supersecretz algorithm=PBEWithMD5AndDES

----ENVIRONMENT-----------------

Runtime: Oracle Corporation Java HotSpot(TM) 64-Bit Server VM 24.45-b08



----ARGUMENTS-------------------

algorithm: PBEWithMD5AndDES
input: contactspassword
password: supersecretz



----OUTPUT----------------------

XcBjfjDDjxeyFBoaEPhG14wEzc6Ja+Xx+hNPrJyQT88=

To easily configure it with Spring Boot you can use its starter jasypt-spring-boot-starter with group ID com.github.ulisesbocchio

Keep in mind, that you will need to start your application using the same password you used to encrypt the properties. So, you can start your app this way:

mvn -Djasypt.encryptor.password=supersecretz spring-boot:run

Or using the environment variable (thanks to spring boot relaxed binding):

export JASYPT_ENCRYPTOR_PASSWORD=supersecretz
mvn spring-boot:run

You can check below link for more details:

https://www.ricston.com/blog/encrypting-properties-in-spring-boot-with-jasypt-spring-boot/

To use your encrypted properties in your app just use it as usual, use either method you like (Spring Boot wires the magic, anyway the property must be of course in the classpath):

Using @Value annotation

@Value("${db.password}")
private String password;

Or using Environment

@Autowired
private Environment environment;

public void doSomething(Environment env) {
    System.out.println(env.getProperty("db.password"));
}

Update: for production environment, to avoid exposing the password in the command line, since you can query the processes with ps, previous commands with history, etc etc. You could:

• Create a script like this: touch setEnv.sh
• Edit setEnv.sh to export the JASYPT_ENCRYPTOR_PASSWORD variable

  #!/bin/bash

  export JASYPT_ENCRYPTOR_PASSWORD=supersecretz

• Execute the file with . setEnv.sh
• Run the app in background with mvn spring-boot:run &
• Delete the file setEnv.sh
• Unset the previous environment variable with: unset JASYPT_ENCRYPTOR_PASSWORD

The issue is that you are not able to get a connection to MYSQL database and hence it is throwing an error saying that cannot build a session factory.

Please see the error below:

 Caused by: java.sql.SQLException: Access denied for user ''@'localhost' (using password: NO) 

which points to username not getting populated.

Please recheck system properties

dataSource.setUsername(System.getProperty("root"));

some packages seems to be missing as well pointing to a dependency issue:

package org.gjt.mm.mysql does not exist

Please run a mvn dependency:tree command to check for dependencies

In Chrome Ver 84, flex: 1 is equivalent to flex: 1 1 0%. The followings are a bunch of screenshots.

Assuming your example text is representative of all the text, one line would consume about 75 bytes on my machine:

In [3]: sys.getsizeof('usedfor zipper fasten_coat')
Out[3]: 75

Doing some rough math:

75 bytes * 8,000,000 lines / 1024 / 1024 = ~572 MB

So roughly 572 meg to store the strings alone for one of these files. Once you start adding in additional, similarly structured and sized files, you'll quickly approach your virtual address space limits, as mentioned in @ShadowRanger's answer.

If upgrading your python isn't feasible for you, or if it only kicks the can down the road (you have finite physical memory after all), you really have two options: write your results to temporary files in-between loading in and reading the input files, or write your results to a database. Since you need to further post-process the strings after aggregating them, writing to a database would be the superior approach.

Angular 2 Provides a very nice feature called as Opaque Constants. Create a class & Define all the constants there using opaque constants.

import { OpaqueToken } from "@angular/core";

export let APP_CONFIG = new OpaqueToken("my.config");

export interface MyAppConfig {
    apiEndpoint: string;
}

export const AppConfig: MyAppConfig = {    
    apiEndpoint: "http://localhost:8080/api/"    
};

Inject it in providers in app.module.ts

You will be able to use it across every components.

EDIT for Angular 4 :

For Angular 4 the new concept is Injection Token & Opaque token is Deprecated in Angular 4.

Injection Token Adds functionalities on top of Opaque Tokens, it allows to attach type info on the token via TypeScript generics, plus Injection tokens, removes the need of adding @Inject

Example Code

Angular 2 Using Opaque Tokens

const API_URL = new OpaqueToken('apiUrl'); //no Type Check


providers: [
  {
    provide: DataService,
    useFactory: (http, apiUrl) => {
      // create data service
    },
    deps: [
      Http,
      new Inject(API_URL) //notice the new Inject
    ]
  }
]

Angular 4 Using Injection Tokens

const API_URL = new InjectionToken<string>('apiUrl'); // generic defines return value of injector


providers: [
  {
    provide: DataService,
    useFactory: (http, apiUrl) => {
      // create data service
    },
    deps: [
      Http,
      API_URL // no `new Inject()` needed!
    ]
  }
]

Injection tokens are designed logically on top of Opaque tokens & Opaque tokens are deprecated in Angular 4.

Cross-platform way of listing all environment variables:

if (isUnix()) {
    sh env
}
else {
    bat set
}

In angular 8:

//for catch:
import { catchError } from 'rxjs/operators';

//for throw:
import { Observable, throwError } from 'rxjs';

//and code should be written like this.

getEmployees(): Observable<IEmployee[]> {
    return this.http.get<IEmployee[]>(this.url).pipe(catchError(this.erroHandler));
  }

  erroHandler(error: HttpErrorResponse) {
    return throwError(error.message || 'server Error');
  }

Spring Boot v2 Gradle plugin docs provide an answer:

6.1. Passing arguments to your application

Like all JavaExec tasks, arguments can be passed into bootRun from the command line using --args='<arguments>' when using Gradle 4.9 or later.

To run server with active profile set to dev:

$ ./gradlew bootRun --args='--spring.profiles.active=dev'

I had the same issue (EF Core) while setting up xUnit tests. What 'fixed' it for me in testing was looping through the change tracker entities after setting up the seed data.

• at the bottom of the SeedAppDbContext() method.

I set up a Test Mock Context:

/// <summary>
/// Get an In memory version of the app db context with some seeded data
/// </summary>
public static AppDbContext GetAppDbContext(string dbName)
{
    //set up the options to use for this dbcontext
    var options = new DbContextOptionsBuilder<AppDbContext>()
        .UseInMemoryDatabase(databaseName: dbName)
        //.UseQueryTrackingBehavior(QueryTrackingBehavior.NoTracking)
        .Options;

    var dbContext = new AppDbContext(options);
    dbContext.SeedAppDbContext();
    return dbContext;
}

Extension method to add some seed data:

• and detach entities in foreach loop at bottom of method.

    public static void SeedAppDbContext(this AppDbContext appDbContext)
    {
       // add companies
       var c1 = new Company() { Id = 1, CompanyName = "Fake Company One", ContactPersonName = "Contact one", eMail = "[email protected]", Phone = "0123456789", AdminUserId = "" };
       c1.Address = new Address() { Id = 1, AddressL1 = "Field Farm", AddressL2 = "Some Lane", City = "some city", PostalCode = "AB12 3CD" };
       appDbContext.CompanyRecords.Add(c1);
                        
       var nc1 = new Company() { Id = 2, CompanyName = "Test Company 2", ContactPersonName = "Contact two", eMail = "[email protected]", Phone = "0123456789", Address = new Address() { }, AdminUserId = "" };
       nc1.Address = new Address() { Id = 2, AddressL1 = "The Barn", AddressL2 = "Some Lane", City = "some city", PostalCode = "AB12 3CD" };
       appDbContext.CompanyRecords.Add(nc1);

       //....and so on....
            
       //last call to commit everything to the memory db
       appDbContext.SaveChanges();

       //and then to detach everything 
       foreach (var entity in appDbContext.ChangeTracker.Entries())
       {
           entity.State = EntityState.Detached;
       }
    }

The controller put method

The .ConvertTo<>() Method is an extension method from ServiceStack

 [HttpPut]
public async Task<IActionResult> PutUpdateCompany(CompanyFullDto company)
{
    if (0 == company.Id)
        return BadRequest();
    try
    {
        Company editEntity = company.ConvertTo<Company>();
        
        //Prior to detaching an error thrown on line below (another instance with id)
        var trackedEntity = _appDbContext.CompanyRecords.Update(editEntity);
        

        await _appDbContext.SaveChangesAsync();
    }
    catch (DbUpdateConcurrencyException dbError)
    {
        if (!CompanyExists(company.Id))
            return NotFound();
        else
            return BadRequest(dbError);
    }
    catch (Exception Error)
    {
        return BadRequest(Error);
    }
    return Ok();
}

and the test:

    [Fact]
    public async Task PassWhenEditingCompany()
    {
        var _appDbContext = AppDbContextMocker.GetAppDbContext(nameof(CompaniesController));
        var _controller = new CompaniesController(null, _appDbContext);

        //Arrange
        const string companyName = "Fake Company One";
        const string contactPerson = "Contact one";

        const string newCompanyName = "New Fake Company One";
        const string newContactPersonName = "New Contact Person";

        //Act
        var getResult = _controller.GetCompanyById(1);
        var getEntity = (getResult.Result.Result as OkObjectResult).Value;
        var entityDto = getEntity as CompanyFullDto;


        //Assert
        Assert.Equal(companyName, entityDto.CompanyName);
        Assert.Equal(contactPerson, entityDto.ContactPersonName);
        Assert.Equal(1, entityDto.Id);

        //Arrange
        Company entity = entityDto.ConvertTo<Company>();
        entity.CompanyName = newCompanyName;
        entity.ContactPersonName = newContactPersonName;
        CompanyFullDto entityDtoUpd = entity.ConvertTo<CompanyFullDto>();

        //Act
        var result = await _controller.PutUpdateCompany(entityDtoUpd) as StatusCodeResult;

        //Assert           
        Assert.True(result.StatusCode == 200);

        //Act
        getResult = _controller.GetCompanyById(1);
        getEntity = (getResult.Result.Result as OkObjectResult).Value;
        
        entityDto = getEntity as CompanyFullDto;
        
        //Assert
        Assert.Equal(1, entityDto.Id); // didn't add a new record
        Assert.Equal(newCompanyName, entityDto.CompanyName); //updated the name
        Assert.Equal(newContactPersonName, entityDto.ContactPersonName); //updated the contact

//make sure to dispose of the _appDbContext otherwise running the full test will fail.
_appDbContext.Dispose();
    }

<div class="button" click="routeWithData()">Pass data and route</div>

well the easiest way to do it in angular 6 or other versions I hope is to simply to define your path with the amount of data you want to pass

{path: 'detailView/:id', component: DetailedViewComponent}

as you can see from my routes definition, I have added the /:id to stand to the data I want to pass to the component via router navigation. Therefore your code will look like

<a class="btn btn-white-view" [routerLink]="[ '/detailView',list.id]">view</a>

in order to read the id on the component, just import ActivatedRoute like

import { ActivatedRoute } from '@angular/router'

and on the ngOnInit is where you retrieve the data

ngOnInit() {
       this.sub = this.route.params.subscribe(params => {
        this.id = params['id'];
        });
        console.log(this.id);
      }

you can read more in this article https://www.tektutorialshub.com/angular-passing-parameters-to-route/

UPDATE: you don't need to convert your values afterwards, you can do it on-the-fly when reading your CSV:

In [165]: df=pd.read_csv(url, index_col=0, na_values=['(NA)']).fillna(0)

In [166]: df.dtypes
Out[166]:
GeoName                    object
ComponentName              object
IndustryId                  int64
IndustryClassification     object
Description                object
2004                        int64
2005                        int64
2006                        int64
2007                        int64
2008                        int64
2009                        int64
2010                        int64
2011                        int64
2012                        int64

2014                      float64
dtype: object

If you need to convert multiple columns to numeric dtypes - use the following technique:

Sample source DF:

In [271]: df
Out[271]:
     id    a  b  c  d  e    f
0  id_3  AAA  6  3  5  8    1
1  id_9    3  7  5  7  3  BBB
2  id_7    4  2  3  5  4    2
3  id_0    7  3  5  7  9    4
4  id_0    2  4  6  4  0    2

In [272]: df.dtypes
Out[272]:
id    object
a     object
b      int64
c      int64
d      int64
e      int64
f     object
dtype: object

Converting selected columns to numeric dtypes:

In [273]: cols = df.columns.drop('id')

In [274]: df[cols] = df[cols].apply(pd.to_numeric, errors='coerce')

In [275]: df
Out[275]:
     id    a  b  c  d  e    f
0  id_3  NaN  6  3  5  8  1.0
1  id_9  3.0  7  5  7  3  NaN
2  id_7  4.0  2  3  5  4  2.0
3  id_0  7.0  3  5  7  9  4.0
4  id_0  2.0  4  6  4  0  2.0

In [276]: df.dtypes
Out[276]:
id     object
a     float64
b       int64
c       int64
d       int64
e       int64
f     float64
dtype: object

PS if you want to select all string (object) columns use the following simple trick:

cols = df.columns[df.dtypes.eq('object')]

In addition to all of the great answers, there is a concept called lazy loading:

Lazy loading is a design pattern commonly used in computer programming to defer initialization of an object until the point at which it is needed.

Using it properly, you can reduce the loading time of your application. And Kotlin way of it's implementation is by lazy() which loads the needed value to your variable whenever it's needed.

But lateinit is used when you are sure a variable won't be null or empty and will be initialized before you use it -e.g. in onResume() method for android- and so you don't want to declare it as a nullable type.

I had exact issue and here is how I fixed:

I found out that I had first installed Keras then installed pandas in my virtual env. When you install keras, pandas is shipped with it. Do not need to pip install pandas.

I tested this hypothesis by creating new virtual environment and wala... pandas appeared without me installing it. Thus I came to the conclusion that pandas is automatically installed when you pip install keras.

In my case, I had to do the following while running with Junit5

@SpringBootTest(classes = {abc.class}) @ExtendWith(SpringExtension.class

Here abc.class was the class that was being tested

I'm probably a bit late to the party, but I wrote the junitcategorizer for my thesis project at TOPdesk. Earlier versions indeed used a company internal Parent POM. So your problems are caused by the Parent POM not being resolvable, since it is not available to the outside world.

You can either:

• Remove the <parent> block, but then have to configure the Surefire, Compiler and other plugins yourself
• (Only applicable to this specific case!) Change it to point to our Open Source Parent POM by setting:

<parent>
    <groupId>com.topdesk</groupId>
    <artifactId>open-source-parent</artifactId>
    <version>1.2.0</version>
</parent>

Define columns by min width based on viewport:

    /* Number of Cards by Row based on Viewport */
    @media (min-width: 576px) {
        .card-deck .card {
            min-width: 50.1%; /* 1 Column */
            margin-bottom: 12px;
        }
    }

    @media (min-width: 768px) {
        .card-deck .card {
            min-width: 33.4%;  /* 2 Columns */
        }
    }

    @media (min-width: 992px) {
        .card-deck .card {
            min-width: 25.1%;  /* 3 Columns */
        }
    }

    @media (min-width: 1200px) {
        .card-deck .card {
            min-width: 20.1%;  /* 4 Columns */
        }
    }

I was getting this error even if I did all the solutions mentioned above.

 by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfig ...

At some point when i look up the POM there was this dependency in it

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

And the Pojo class had the following imports

import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id;

Which clearly shows the application was expecting a datasource.

What I did was I removed the JPA dependency from pom and replaced the imports for the pojo with the following once

import org.springframework.data.annotation.Id; import org.springframework.data.mongodb.core.mapping.Document;

Finally I got SUCCESSFUL build. Check it out you might have run into the same problem

I got the same error and changing the following

SessionFactory sessionFactory =
    new Configuration().configure().buildSessionFactory();

to this

SessionFactory sessionFactory =
    new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();

worked for me.

Just add the following line to disable spring auto configuration in application.properties file

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration

it works on spring 2.0.5 :)

It's exactly what the error says. You didn't create any RestTemplate bean, so it can't autowire any. If you need a RestTemplate you'll have to provide one. For example, add the following to TestMicroServiceApplication.java:

@Bean
public RestTemplate restTemplate() {
    return new RestTemplate();
}

Note, in earlier versions of the Spring cloud starter for Eureka, a RestTemplate bean was created for you, but this is no longer true.

Here is the best solution for this. (ANGULAR All Version)

Addressing solution: To set a default value for @Input variable. If no value passed to that input variable then It will take the default value.

I have provided solution for this kind of similar question. You can find the full solution from here

export class CarComponent implements OnInit {
  private _defaultCar: car = {
    // default isCar is true
    isCar: true,
    // default wheels  will be 4
    wheels: 4
  };

  @Input() newCar: car = {};

  constructor() {}

  ngOnInit(): void {

   // this will concate both the objects and the object declared later (ie.. ...this.newCar )
   // will overwrite the default value. ONLY AND ONLY IF DEFAULT VALUE IS PRESENT

    this.newCar = { ...this._defaultCar, ...this.newCar };
   //  console.log(this.newCar);
  }
}

For nested html, use closest

<button (click)="toggle($event)" class="someclass" id="btn1">
    <i class="fa fa-user"></i>
</button>

toggle(event) {
   (event.target.closest('button') as Element).id; 
}

This route I take is one where I create functions outside the class and assign the function to my private method.

export class MyClass {
  private _myPrivateFunction = someFunctionThatCanBeTested;
}

function someFunctionThatCanBeTested() {
  //This Is Testable
}

Now I don't know what type of OOP rules I am breaking, but to answer the question, this is how I test private methods. I welcome anyone to advise on Pros & Cons of this.

For compatibility with Tensorflow 2.0, you can use tf.get_logger

import logging
tf.get_logger().setLevel(logging.ERROR)

If you want to set width dynamically with variable than use [] braces instead {{}}:

 <div [style.width.px]="[widthVal]"  [style.height.px]="[heightVal]"></div>

 <div [style.width.%]="[widthVal]"  [style.height.%]="[heightVal]"></div>

Here is a snippet code through a chain of environments properties files are being loaded for different environments.

Properties file under your application resources ( src/main/resources ):-

 1. application.properties
 2. application-dev.properties
 3. application-uat.properties
 4. application-prod.properties

Ideally, application.properties contains all common properties which are accessible for all environments and environment related properties only works on specifies environment. therefore the order of loading these properties files will be in such way -

 application.properties -> application.{spring.profiles.active}.properties.

Code snippet here :-

    import org.springframework.context.support.PropertySourcesPlaceholderConfigurer;
    import org.springframework.core.io.ClassPathResource;
    import org.springframework.core.io.Resource;

    public class PropertiesUtils {

        public static final String SPRING_PROFILES_ACTIVE = "spring.profiles.active";

        public static void initProperties() {
            String activeProfile = System.getProperty(SPRING_PROFILES_ACTIVE);
            if (activeProfile == null) {
                activeProfile = "dev";
            }
            PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer
                    = new PropertySourcesPlaceholderConfigurer();
            Resource[] resources = new ClassPathResource[]
                    {new ClassPathResource("application.properties"),
                            new ClassPathResource("application-" + activeProfile + ".properties")};
            propertySourcesPlaceholderConfigurer.setLocations(resources);

        }
    }

Run hive in debug mode

hive -hiveconf hive.root.logger=DEBUG,console

and then execute

show tables

can find the actual problem

I had to use

powershell.AddCommand("Get-ADPermission");
powershell.AddParameter("Identity", "complete id path with OU in it");

to get past this error

#Try without dot notation
sample_dict = {'name': 'John', 'age': 29}
print(sample_dict['name']) # John
print(sample_dict['age']) # 29

Some times appeared if you declare a constant in the header file without static notation. like this

const int k = 10;

it should be:

static const int k = 10;

If you have a single play that you want to loop over the items, define that list in group_vars/all or somewhere else that makes sense:

all_items:
  - first
  - second
  - third
  - fourth

Then your task can look like this:

  - name: List items or default list
    debug:
      var: item
    with_items: "{{ varlist | default(all_items) }}"

Pass in varlist as a JSON array:

ansible-playbook <playbook_name> --extra-vars='{"varlist": [first,third]}'

Prior to that, you might also want a task that checks that each item in varlist is also in all_items:

  - name: Ensure passed variables are in all_items
    fail:
      msg: "{{ item }} not  in all_items list"
    when: item not in all_items
    with_items: "{{ varlist | default(all_items) }}"

It is depends on the case and the usage. Generally, in TypeScript there are no default values for interfaces.

If you don't use the default values
You can declare x as:

let x: IX | undefined; // declaration: x = undefined

Then, in your init function you can set real values:

x = {
    a: 'xyz'
    b: 123
    c: new AnotherType()
};

In this way, x can be undefined or defined - undefined represents that the object is uninitialized, without set the default values, if they are unnecessary. This is loggically better than define "garbage".

If you want to partially assign the object:
You can define the type with optional properties like:

interface IX {
    a: string,
    b?: any,
    c?: AnotherType
}

In this case you have to set only a. The other types are marked with ? which mean that they are optional and have undefined as default value.

In any case you can use undefined as a default value, it is just depends on your use case.

Webpack and Browserify

Webpack and Browserify do pretty much the same job, which is processing your code to be used in a target environment (mainly browser, though you can target other environments like Node). Result of such processing is one or more bundles - assembled scripts suitable for targeted environment.

For example, let's say you wrote ES6 code divided into modules and want to be able to run it in a browser. If those modules are Node modules, the browser won't understand them since they exist only in the Node environment. ES6 modules also won't work in older browsers like IE11. Moreover, you might have used experimental language features (ES next proposals) that browsers don't implement yet so running such script would just throw errors. Tools like Webpack and Browserify solve these problems by translating such code to a form a browser is able to execute. On top of that, they make it possible to apply a huge variety of optimisations on those bundles.

However, Webpack and Browserify differ in many ways, Webpack offers many tools by default (e.g. code splitting), while Browserify can do this only after downloading plugins but using both leads to very similar results. It comes down to personal preference (Webpack is trendier). Btw, Webpack is not a task runner, it is just processor of your files (it processes them by so called loaders and plugins) and it can be run (among other ways) by a task runner.

Webpack Dev Server

Webpack Dev Server provides a similar solution to Browsersync - a development server where you can deploy your app rapidly as you are working on it, and verify your development progress immediately, with the dev server automatically refreshing the browser on code changes or even propagating changed code to browser without reloading with so called hot module replacement.

Task runners vs NPM scripts

I've been using Gulp for its conciseness and easy task writing, but have later found out I need neither Gulp nor Grunt at all. Everything I have ever needed could have been done using NPM scripts to run 3rd-party tools through their API. Choosing between Gulp, Grunt or NPM scripts depends on taste and experience of your team.

While tasks in Gulp or Grunt are easy to read even for people not so familiar with JS, it is yet another tool to require and learn and I personally prefer to narrow my dependencies and make things simple. On the other hand, replacing these tasks with the combination of NPM scripts and (propably JS) scripts which run those 3rd party tools (eg. Node script configuring and running rimraf for cleaning purposes) might be more challenging. But in the majority of cases, those three are equal in terms of their results.

Examples

As for the examples, I suggest you have a look at this React starter project, which shows you a nice combination of NPM and JS scripts covering the whole build and deploy process. You can find those NPM scripts in package.json in the root folder, in a property named scripts. There you will mostly encounter commands like babel-node tools/run start. Babel-node is a CLI tool (not meant for production use), which at first compiles ES6 file tools/run (run.js file located in tools) - basically a runner utility. This runner takes a function as an argument and executes it, which in this case is start - another utility (start.js) responsible for bundling source files (both client and server) and starting the application and development server (the dev server will be probably either Webpack Dev Server or Browsersync).

Speaking more precisely, start.js creates both client and server side bundles, starts an express server and after a successful launch initializes Browser-sync, which at the time of writing looked like this (please refer to react starter project for the newest code).

const bs = Browsersync.create();  
bs.init({
      ...(DEBUG ? {} : { notify: false, ui: false }),

      proxy: {
        target: host,
        middleware: [wpMiddleware, ...hotMiddlewares],
      },

      // no need to watch '*.js' here, webpack will take care of it for us,
      // including full page reloads if HMR won't work
      files: ['build/content/**/*.*'],
}, resolve)

The important part is proxy.target, where they set server address they want to proxy, which could be http://localhost:3000, and Browsersync starts a server listening on http://localhost:3001, where the generated assets are served with automatic change detection and hot module replacement. As you can see, there is another configuration property files with individual files or patterns Browser-sync watches for changes and reloads the browser if some occur, but as the comment says, Webpack takes care of watching js sources by itself with HMR, so they cooperate there.

Now I don't have any equivalent example of such Grunt or Gulp configuration, but with Gulp (and somewhat similarly with Grunt) you would write individual tasks in gulpfile.js like

gulp.task('bundle', function() {
  // bundling source files with some gulp plugins like gulp-webpack maybe
});

gulp.task('start', function() {
  // starting server and stuff
});

where you would be doing essentially pretty much the same things as in the starter-kit, this time with task runner, which solves some problems for you, but presents its own issues and some difficulties during learning the usage, and as I say, the more dependencies you have, the more can go wrong. And that is the reason I like to get rid of such tools.

To overcome the null / undefined issue, try using the ? operator to check existence:

<p ng-if="post?.capabilities?.items?.length > 0">

• Sidenote, if anyone got to this page looking for an Ionic Framework answer, ensure you use *ngIf:

  <p *ngIf="post?.capabilities?.items?.length > 0">
  

It happens because Build Tools revision 24.4.1 doesn't exist.

The latest version is 23.0.2.
These tools is included in the SDK package and installed in the <sdk>/build-tools/ directory.

Don't confuse the Android SDK Tools with SDK Build Tools.

Change in your build.gradle

android {
   buildToolsVersion "23.0.2"
   // ...

}

I had Android Studio version 1.5.1 installed and was running into this error. I have the following buildscript (which was working on Ubuntu but not Windows):

buildscript {
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'
    }
}

I tried:

1. gradlew clean
2. Use default gradle wrapper (recommended)
3. Use local distribution and linked to downloaded gradle 2.2.1 binary

None of these solutions worked unfortunately. It should be worth noting that upgrading Android Studio from 1.5.1 to 2.1.1 also failed with errors about 2.10 missing so could not be performed.

Solution: What I ended up doing was simply downloaded the latest stable version of Android Studio and installing that instead (2.1.1 at the time). After doing that gradle synced succesfully

In Case of Arrays you can do it like this:

In .ts file (Parent component) where you are updating your rawLapsData do it like this:

rawLapsData = somevalue; // change detection will not happen

Solution:

rawLapsData = {...somevalue}; //change detection will happen

and ngOnChanges will called in child component

The problem is that when we use application/x-www-form-urlencoded, Spring doesn't understand it as a RequestBody. So, if we want to use this we must remove the @RequestBody annotation.

Then try the following:

@RequestMapping(value = "/patientdetails", method = RequestMethod.POST,consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
public @ResponseBody List<PatientProfileDto> getPatientDetails(
        PatientProfileDto name) {


    List<PatientProfileDto> list = new ArrayList<PatientProfileDto>();
    list = service.getPatient(name);
    return list;
}

Note that removed the annotation @RequestBody

Look at this photo, it says "Kebab Menu" is a correct answer:

per comment below, sourced from Luke Wroblewski: https://twitter.com/lukew/status/591296890030915585/photo/1

Use ./gradlew instead of gradle to resolve this issue.

1)check the package name is the same in google-services.json file

2)make sure that no other project exist with same package name

3)make sure that there is internet access

4)try syncing project and running it again

Updated to angular2 beta 8

Now as from angular2 beta 8 we can use *ngIf and *ngFor on same component see here.

Alternate:

Sometimes we can't use HTML tags inside another like in tr, th (table) or in li (ul). We cannot use another HTML tag but we have to perform some action in same situation so we can HTML5 feature tag <template> in this way.

ngFor using template:

<template ngFor #abc [ngForOf]="someArray">
    code here....
</template>

ngIf using template:

<template [ngIf]="show">
    code here....
</template>    

For more information about structural directives in angular2 see here.

You can run this command in your project directory. Basically it just cleans the build and gradle.

   cd android && rm -R .gradle && cd app && rm -R build

In my case, I was using react-native using this as a script in package.json

"scripts": { "clean-android": "cd android && rm -R .gradle && cd app && rm -R build" }

You need to use the Navigation component in the template of ObservingComponent ( dont't forget to add a selector to Navigation component .. navigation-component for ex )

<navigation-component (navchange)='onNavGhange($event)'></navigation-component>

And implement onNavGhange() in ObservingComponent

onNavGhange(event) {
  console.log(event);
}

Last thing .. you don't need the events attribute in @Componennt

events : ['navchange'], 

When distribute to App Store, you choose Product -> Achieve and encounter "code sign error, no matching provisioning profiles found", if account and downloaded .mobileprovision file is ok. Try click the "Build and Run" button to run it on your phone.

And, a dialog box will popup with a button "Fix", just click "Fix" to do next... Last, your device will have an valid provisioning file. Just do "Product -> Achieve" again, everything is OK!

You can use sudo ip link delete to remove the interface.

Problem: The accepted answer does not actually fix the indentation in the current document.

Solution: Run Format Document to re-process the document according to current (new) settings.

Problem: The HTML docs in my projects are of type "Django HTML" not "HTML" and there is no formatter available.

Solution: Switch them to syntax "HTML", format them, then switch back to "Django HTML."

Problem: The HTML formatter doesn't know how to handle Django template tags and undoes much of my carefully applied nesting.

Solution: Install the Indent 4-2 extension, which performs indentation strictly, without regard to the current language syntax (which is what I want in this case).

If you are inside of Spring bean (in this case @Controller bean) you shouldn't use Spring context instance at all. Just autowire className bean directly.

BTW, avoid using field injection as it's considered as bad practice.

You don't have any example code but I assume you want to do something like this?

@View({
directives: [NgClass],
styles: [`
    .${TodoModel.COMPLETED}  {
        text-decoration: line-through;
    }
    .${TodoModel.STARTED} {
        color: green;
    }
`],
template: `<div>
                <span [ng-class]="todo.status" >{{todo.title}}</span>
                <button (click)="todo.toggle()" >Toggle status</button>
            </div>`
})

You assign ng-class to a variable which is dynamic (a property of a model called TodoModel as you can guess).

todo.toggle() is changing the value of todo.status and there for the class of the input is changing.

This is an example for class name but actually you could do the same think for css properties.

I hope this is what you meant.

This example is taken for the great egghead tutorial here.

When you run your application as an jar, your Manifest.MF file should know which class has the main method.

To add this information when SpringBoot compiles your code, add start-class property on your pom file.

E.g.:

<properties>
        <start-class>com.example.DemoApplication</start-class>
</properties>

OP here (I am answering this question after two years, the post made by Daniel Cerecedo was not bad at a time, but the web services are developing very fast)

After three years of full-time software development (with focus also on software architecture, project management and microservice architecture) I definitely choose the second way (but with one general endpoint) as the best one.

If you have a special endpoint for images, it gives you much more power over handling those images.

We have the same REST API (Node.js) for both - mobile apps (iOS/android) and frontend (using React). This is 2017, therefore you don't want to store images locally, you want to upload them to some cloud storage (Google cloud, s3, cloudinary, ...), therefore you want some general handling over them.

Our typical flow is, that as soon as you select an image, it starts uploading on background (usually POST on /images endpoint), returning you the ID after uploading. This is really user-friendly, because user choose an image and then typically proceed with some other fields (i.e. address, name, ...), therefore when he hits "send" button, the image is usually already uploaded. He does not wait and watching the screen saying "uploading...".

The same goes for getting images. Especially thanks to mobile phones and limited mobile data, you don't want to send original images, you want to send resized images, so they do not take that much bandwidth (and to make your mobile apps faster, you often don't want to resize it at all, you want the image that fits perfectly into your view). For this reason, good apps are using something like cloudinary (or we do have our own image server for resizing).

Also, if the data are not private, then you send back to app/frontend just URL and it downloads it from cloud storage directly, which is huge saving of bandwidth and processing time for your server. In our bigger apps there are a lot of terabytes downloaded every month, you don't want to handle that directly on each of your REST API server, which is focused on CRUD operation. You want to handle that at one place (our Imageserver, which have caching etc.) or let cloud services handle all of it.

Cons : The only "cons" which you should think of is "not assigned images". User select images and continue with filling other fields, but then he says "nah" and turn off the app or tab, but meanwhile you successfully uploaded the image. This means you have uploaded an image which is not assigned anywhere.

There are several ways of handling this. The most easiest one is "I don't care", which is a relevant one, if this is not happening very often or you even have desire to store every image user send you (for any reason) and you don't want any deletion.

Another one is easy too - you have CRON and i.e. every week and you delete all unassigned images older than one week.

JSX:

<select value={ this.state.foo } onChange={this.handleFooChange}>
    <option value="A">A</option>
    <option value="B">B</option>
</select>

TypeScript:

private handleFooChange = (event: React.FormEvent<HTMLSelectElement>) => {
    const element = event.target as HTMLSelectElement;
    this.setState({ foo: element.value });
}

I faced the same issue, spent too much calories searching for the right fix until I decided to settle down with file reading:

Properties configProps = new Properties();
InputStream iStream = new ClassPathResource("myapp-test.properties").getInputStream();
InputStream iStream = getConfigFile();
configProps.load(iStream);

I managed to fix it finally. The problem is not related to HikariCP. The problem persisted because of some complex methods in REST controllers executing multiple changes in DB through JPA repositories. For some reasons calls to these interfaces resulted in a growing number of "freezed" active connections, exhausting the pool. Either annotating these methods as @Transactional or enveloping all the logic in a single call to transactional service method seem to solve the problem.

I have searched a lot for a solution in which I can compare two array of objects with different attribute names (something like a left outer join). I came up with this solution. Here I used Lodash. I hope this will help you.

var Obj1 = [
    {id:1, name:'Sandra'},
    {id:2, name:'John'},   
];

var Obj2 = [
    {_id:2, name:'John'},
    {_id:4, name:'Bobby'}
];

var Obj3 = lodash.differenceWith(Obj1, Obj2, function (o1, o2) {
    return o1['id'] === o2['_id']
});

console.log(Obj3);
//  {id:1, name:'Sandra'}

I've uploaded a simple java program which takes your project location and the dimension file you want as input. Based on that, it would output the corresponding dimension file in the console. Here's the link to it:

https://github.com/akeshwar/Dimens-for-different-screens-in-Android/blob/master/Main.java

Here's the full code for the reference:

public class Main {


    /**
     * You can change your factors here. The current factors are in accordance with the official documentation.
     */
    private static final double LDPI_FACTOR = 0.375;
    private static final double MDPI_FACTOR = 0.5;
    private static final double HDPI_FACTOR = 0.75;
    private static final double XHDPI_FACTOR = 1.0;
    private static final double XXHDPI_FACTOR = 1.5;
    private static final double XXXHDPI_FACTOR = 2.0;

    private static double factor;

    public static void main(String[] args) throws IOException {


        Scanner in = new Scanner(System.in);
        System.out.println("Enter the location of the project/module");
        String projectPath = in.nextLine();

        System.out.println("Which of the following dimension file do you want?\n1. ldpi \n2. mdpi \n3. hdpi \n4. xhdpi \n5. xxhdpi \n6. xxxhdpi");

        int dimenType = in.nextInt();

        switch (dimenType) {
            case 1: factor = LDPI_FACTOR;
                break;
            case 2: factor = MDPI_FACTOR;

                break;
            default:

        String fullPath = projectPath + "/src/main/res/values/dimens.xml";

        FileInputStream fstream = new FileInputStream(fullPath);
        BufferedReader br = new BufferedReader(new InputStreamReader(fstream));

        String strLine;

        while ((strLine = br.readLine()) != null)   {
            modifyLine(strLine);
        }
        br.close();

    }

    private static void modifyLine(String line) {

        /**
         * Well, this is how I'm detecting if the line has some dimension value or not.
         */
        if(line.contains("p</")) {
            int endIndex = line.indexOf("p</");

            //since indexOf returns the first instance of the occurring string. And, the actual dimension would follow after the first ">" in the screen
            int begIndex = line.indexOf(">");

            String prefix = line.substring(0, begIndex+1);
            String root = line.substring(begIndex+1, endIndex-1);
            String suffix = line.substring(endIndex-1,line.length());


            /**
             * Now, we have the root. We can use it to create different dimensions. Root is simply the dimension number.
             */

            double dimens = Double.parseDouble(root);
            dimens = dimens*factor*1000;
            dimens = (double)((int)dimens);
            dimens = dimens/1000;
            root = dimens + "";

            System.out.println(prefix + " " +  root + " " + suffix );

        }

        System.out.println(line);
    }
}

In my case I had created a SB app from the SB Initializer and had included a fair number of deps in it to other things. I went in and commented out the refs to them in the build.gradle file and so was left with:

implementation 'org.springframework.boot:spring-boot-starter-hateoas'
compileOnly 'org.projectlombok:lombok'
developmentOnly 'org.springframework.boot:spring-boot-devtools'
runtimeOnly 'org.hsqldb:hsqldb'
runtimeOnly 'org.postgresql:postgresql'
annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'
annotationProcessor 'org.projectlombok:lombok'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
testImplementation 'org.springframework.restdocs:spring-restdocs-mockmvc'

as deps. Then my bare-bones SB app was able to build and get running successfully. As I go to try to do things that may need those commented-out libs I will add them back and see what breaks.

I solved this without deleting the app

With the project open in xcode. Project -> Build Settings -> Code Signing -> Provisioning Profiles (drop down) It is probably set to automatic and is choosing the wrong profile. Open the drop down and choose the correct one, then re-run the app.

If you create and android studio project, You can see a local.properties file is created inside your project root directory. When you create a react native project, It doesn't create that file for you. So you have to create it manually. And have to add skd dir to it. So create a new file inside android folder ( on root ). and put your sdk path like this sdk.dir=D\:\\Android\\SDK\\android_sdk_studio . Remember: remove single \ with double. Just like above.

I tried 2 solutions, both work.

Solution_1

        private String username;
        private String password;
    }

}

List<LoginInfos.LoginInfo> list = loginInfos.getConfigurations();

Solution_2

available-users-list: '[{"username":"eXvn817zHBVn2QLQ==","password":"IfWKJLIMVeY7Q=="}, {"username":"uwJlOl/g9jP6/0w==","password":"IP2qWKJLIMVeY7Q=="}]'

LoginInfos.LoginInfo[] array = mapper.readValue(testList, LoginInfos.LoginInfo[].class);

Add an onClick handler to your top level container and increment a state value whenever the user clicks within. Pass that value to the relevant component and whenever the value changes you can do work.

In this case we're calling this.closeDropdown() whenever the clickCount value changes.

The incrementClickCount method fires within the .app container but not the .dropdown because we use event.stopPropagation() to prevent event bubbling.

Your code may end up looking something like this:

class App extends Component {
    constructor(props) {
        super(props);
        this.state = {
            clickCount: 0
        };
    }
    incrementClickCount = () => {
        this.setState({
            clickCount: this.state.clickCount + 1
        });
    }
    render() {
        return (
            <div className="app" onClick={this.incrementClickCount}>
                <Dropdown clickCount={this.state.clickCount}/>
            </div>
        );
    }
}
class Dropdown extends Component {
    constructor(props) {
        super(props);
        this.state = {
            open: false
        };
    }
    componentDidUpdate(prevProps) {
        if (this.props.clickCount !== prevProps.clickCount) {
            this.closeDropdown();
        }
    }
    toggleDropdown = event => {
        event.stopPropagation();
        return (this.state.open) ? this.closeDropdown() : this.openDropdown();
    }
    render() {
        return (
            <div className="dropdown" onClick={this.toggleDropdown}>
                ...
            </div>
        );
    }
}

The justify-self and justify-items properties are not implemented in flexbox. This is due to the one-dimensional nature of flexbox, and that there may be multiple items along the axis, making it impossible to justify a single item. To align items along the main, inline axis in flexbox you use the justify-content property.

Reference: Box alignment in CSS Grid Layout

Couldn't add this as a comment, but in case anyone is interested in using the accepted answer with subplots, the divider should be formed on specific axes object (rather than on the numpy.ndarray returned from plt.subplots)

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
data = np.arange(100, 0, -1).reshape(10, 10)
fig, ax = plt.subplots(ncols=2, nrows=2)
for row in ax:
    for col in row:
        im = col.imshow(data, cmap='bone')
        divider = make_axes_locatable(col)
        cax = divider.append_axes('right', size='5%', pad=0.05)
        fig.colorbar(im, cax=cax, orientation='vertical')
plt.show()

You might be best starting with reading this post by Dan Abramov where he discusses various implementations of Flux and their trade-offs at the time he was writing redux: The Evolution of Flux Frameworks

Secondly that motivations page you link to does not really discuss the motivations of Redux so much as the motivations behind Flux (and React). The Three Principles is more Redux specific though still does not deal with the implementation differences from the standard Flux architecture.

Basically, Flux has multiple stores that compute state change in response to UI/API interactions with components and broadcast these changes as events that components can subscribe to. In Redux, there is only one store that every component subscribes to. IMO it feels at least like Redux further simplifies and unifies the flow of data by unifying (or reducing, as Redux would say) the flow of data back to the components - whereas Flux concentrates on unifying the other side of the data flow - view to model.

I removed the mode from

<tx:annotation-driven mode="aspectj"
transaction-manager="transactionManager" />

to make this work

My Point , IN this arent way asking developer to create all environment related in single go, resulting in risk of exposing Production Configuration to end developer

as per 12-Factor, shouldnt be enviornment specific reside in Enviornment only .

How do we do for CI CD

• Build Spring one time and promote to aother environment, in that case, if we have spring jar has all environment, it iwll security risk, having all environment variable in GIT

I created a symbol link like described by Clézio before. However, I had to specify a suitable encoding (e.g chcp 65001) in command line before.

chcp 65001
mklink /D "C:\android-sdk" "C:\Users\René\AppData\Local\Android\sdk"

If you have your SDK installed under Path C:\Users[USER]\AppData... you may have to run command line with administrativ priviledges.

I solve this problem, the reason is: You downloaded other's projects. His local.properties file content is his SDK path. You must replace SDK path with your local SDK path, then rebuild the project.

Wrong syntax. Here you are:

insert into user_by_category (game_category,customer_id) VALUES ('Goku','12');

or:

insert into user_by_category ("game_category","customer_id") VALUES ('Kakarot','12');

The second one is normally used for case-sensitive column names.

If you use SonarScanner CLI with Docker, you may have this error because the SonarScanner container can not access to the Sonar UI container.

Note that you will have the same error with a simple curl from another container:

docker run --rm byrnedo/alpine-curl 127.0.0.1:9000
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
curl: (7) Failed to connect to 127.0.0.1 port 8080: Connection refused

The solution is to connect the SonarScanner container to the same docker network of your sonar instance, for instance with --network=host:

docker run --network=host -e SONAR_HOST_URL='http://127.0.0.1:9000' --user="$(id -u):$(id -g)" -v "$PWD:/usr/src" sonarsource/sonar-scanner-cli

(other parameters of this command comes from the SonarScanner CLI documentation)

On Windows you can include the windows library and use "Sleep(0);" to sleep the program. It takes a value that represents milliseconds.

Use the Date object's getTime() method, which returns the number of milliseconds since 1 January 1970 00:00:00 UTC (epoch time):

var date = new Date();
var copiedDate = new Date(date.getTime());

In Safari 4, you can also write:

var date = new Date();
var copiedDate = new Date(date);

...but I'm not sure whether this works in other browsers. (It seems to work in IE8).

Try this too

 $url = 'http://www.domain.com/';
    $html = file_get_contents($url);

    //Change encoding to UTF-8 from ISO-8859-1
    $html = iconv('UTF-8', 'ISO-8859-1//TRANSLIT', $html);

The OVER clause is powerful in that you can have aggregates over different ranges ("windowing"), whether you use a GROUP BY or not

Example: get count per SalesOrderID and count of all

SELECT
    SalesOrderID, ProductID, OrderQty
    ,COUNT(OrderQty) AS 'Count'
    ,COUNT(*) OVER () AS 'CountAll'
FROM Sales.SalesOrderDetail 
WHERE
     SalesOrderID IN(43659,43664)
GROUP BY
     SalesOrderID, ProductID, OrderQty

Get different COUNTs, no GROUP BY

SELECT
    SalesOrderID, ProductID, OrderQty
    ,COUNT(OrderQty) OVER(PARTITION BY SalesOrderID) AS 'CountQtyPerOrder'
    ,COUNT(OrderQty) OVER(PARTITION BY ProductID) AS 'CountQtyPerProduct',
    ,COUNT(*) OVER () AS 'CountAllAgain'
FROM Sales.SalesOrderDetail 
WHERE
     SalesOrderID IN(43659,43664)

setTimeout may help out here

$("#message_link").click(function(){
   setTimeout(function() {
       if (some_conditions...){
           $("#header").append("<div><img alt=\"Loader\"src=\"/images/ajax-loader.gif\"  /></div>");
       }
   }, 100);
});

That will cause the div to be appended ~100ms after the click event occurs, if some_conditions are met.

See my post here

How are you? I had the same problem while i was trying connect to MSSQL Server remotely using jdbc (dbeaver on debian).

After a while, i found out that my firewall configuration was not correctly. So maybe it could help you!

Configure the firewall to allow network traffic that is related to SQL Server and to the SQL Server Browser service.

Four exceptions must be configured in Windows Firewall to allow access to SQL Server:

A port exception for TCP Port 1433. In the New Inbound Rule Wizard dialog, use the following information to create a port exception: Select Port Select TCP and specify port 1433 Allow the connection Choose all three profiles (Domain, Private & Public) Name the rule “SQL – TCP 1433" A port exception for UDP Port 1434. Click New Rule again and use the following information to create another port exception: Select Port Select UDP and specify port 1434 Allow the connection Choose all three profiles (Domain, Private & Public) Name the rule “SQL – UDP 1434 A program exception for sqlservr.exe. Click New Rule again and use the following information to create a program exception: Select Program Click Browse to select ‘sqlservr.exe’ at this location: [C:\Program Files\Microsoft SQL Server\MSSQL11.\MSSQL\Binn\sqlservr.exe] where is the name of your SQL instance. Allow the connection Choose all three profiles (Domain, Private & Public) Name the rule SQL – sqlservr.exe A program exception for sqlbrowser.exe Click New Rule again and use the following information to create another program exception: Select Program Click Browse to select sqlbrowser.exe at this location: [C:\Program Files\Microsoft SQL Server\90\Shared\sqlbrowser.exe].

If I understand correctly you want to change the CSS style of an element by clicking an item in a ul list. Am I right?

HTML:

<div class="results" style="background-color:Red;">
</div>

 <ul class="colors-list">
     <li>Red</li>
     <li>Blue</li>
     <li>#ffee99</li>
 </ul>

jquery

$('.colors-list li').click(function(e){
    var color = $(this).text();
    $('.results').css('background-color',color);
});

Note that jquery can use addClass, removeClass and toggleClass if you want to use classes rather than inline styling. This means that you can do something like that:

$('.results').addClass('selected');

And define the 'selected' styling in the CSS.

Working example: http://jsfiddle.net/uuJmP/

According to Google documentation they said that this is the best way to do it. First create this function to find out how many markers there are/

   function setMapOnAll(map1) {
    for (var i = 0; i < markers.length; i++) {
      markers[i].setMap(map1);
    }
  }

Next create another function to take away all these markers

 function clearMarker(){
setMapOnAll(null);
}

Then create this final function to erase all the markers when ever this function is called upon.

 function delateMarkers(){
clearMarker()
markers = []
//console.log(markers) This is just if you want to

}

Hope that helped good luck

Possibly you can do group by user and then order by time desc. Something like as below

  SELECT * FROM lms_attendance group by user order by time desc;

Taking help from above answer link mentioned in the above answer sets the max value with option

yAxis: { max: 100 },

On similar line min value can be set.So if you want to set min-max value then

yAxis: {
   min: 0,     
   max: 100
},

If you are using HighRoller php library for integration if Highchart graphs then you just need to set the option

$series->yAxis->min=0;
$series->yAxis->max=100;

you could use an onchange event to trigger a validation and then you can display a toast if this is enough for you

In short:

• getPath() gets the path string that the File object was constructed with, and it may be relative current directory.
• getAbsolutePath() gets the path string after resolving it against the current directory if it's relative, resulting in a fully qualified path.
• getCanonicalPath() gets the path string after resolving any relative path against current directory, and removes any relative pathing (. and ..), and any file system links to return a path which the file system considers the canonical means to reference the file system object to which it points.

Also, each of these has a File equivalent which returns the corresponding File object.

Note that IMO, Java got the implementation of an "absolute" path wrong; it really should remove any relative path elements in an absolute path. The canonical form would then remove any FS links or junctions in the path.

Quick and dirty version:

byte[] fileBytes = File.ReadAllBytes(inputFilename);
StringBuilder sb = new StringBuilder();

foreach(byte b in fileBytes)
{
    sb.Append(Convert.ToString(b, 2).PadLeft(8, '0'));  
}

File.WriteAllText(outputFilename, sb.ToString());

In simple words, strace traces all system calls issued by a program along with their return codes. Think things such as file/socket operations and a lot more obscure ones.

It is most useful if you have some working knowledge of C since here system calls would more accurately stand for standard C library calls.

Let's say your program is /usr/local/bin/cough. Simply use:

strace /usr/local/bin/cough <any required argument for cough here>

or

strace -o <out_file> /usr/local/bin/cough <any required argument for cough here>

to write into 'out_file'.

All strace output will go to stderr (beware, the sheer volume of it often asks for a redirection to a file). In the simplest cases, your program will abort with an error and you'll be able to see what where its last interactions with the OS in strace output.

More information should be available with:

man strace

if you want to rotate inline elements, you should set the inline element to inline-block first.

i {
  display: inline-block;
}

i:hover {
  animation: rotate-btn .5s linear 3;
  -webkit-animation: rotate-btn .5s linear 3;
}

@keyframes rotate-btn {
  0% {
    transform: rotate(0);
  }
  100% {
    transform: rotate(-360deg);
  }
}

You can also simply create ONLY a UIView in Interface builder and drag & drop the ImageView and UILabel (to make it look like your desired header) and then use that.

Once your UIView looks like the way you want it too, you can programmatically initialize it from the XIB and add to your UITableView. In other words, you dont have to design the ENTIRE table in IB. Just the headerView (this way the header view can be reused in other tables as well)

For example I have a custom UIView for one of my table headers. The view is managed by a xib file called "CustomHeaderView" and it is loaded into the table header using the following code in my UITableViewController subclass:

-(UIView *) customHeaderView {
    if (!customHeaderView) {
        [[NSBundle mainBundle] loadNibNamed:@"CustomHeaderView" owner:self options:nil];
    }

    return customHeaderView;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Set the CustomerHeaderView as the tables header view 
    self.tableView.tableHeaderView = self.customHeaderView;
}

I think you do not need to use shape if I understood you.

If you are looking as shown in following image then use following layout.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:background="#1bd4f6"
    android:paddingBottom="4dp" >

    <TextView
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:background="#ababb2"
        android:padding="5dp"
        android:text="Hello Android" />
 </RelativeLayout>

 </RelativeLayout>

EDIT

play with these properties you will get result

    android:top="dimension"
    android:right="dimension"
    android:bottom="dimension"
    android:left="dimension"

try like this

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

<item>
    <shape android:shape="rectangle" >
        <solid android:color="#1bd4f6" />
    </shape>
</item>

<item android:top="20px"
    android:left="0px">
    <shape android:shape="line"  >
        <padding android:bottom="1dp" />

        <stroke
            android:dashGap="10px"
            android:dashWidth="10px"
            android:width="1dp"
            android:color="#ababb2" />
    </shape>
</item>

</layer-list>

As Get-Date returns a DateTime object you are able to compare them directly. An example:

(get-date 2010-01-02) -lt (get-date 2010-01-01)

will return false.

You cannot use a select statement that assigns values to variables to also return data to the user The below code will work fine, because i have declared 1 local variable and that variable is used in select statement.

 Begin
    DECLARE @name nvarchar(max)
    select @name=PolicyHolderName from Table
    select @name
    END

The below code will throw error "A SELECT statement that assigns a value to a variable must not be combined with data-retrieval operations" Because we are retriving data(PolicyHolderAddress) from table, but error says data-retrieval operation is not allowed when you use some local variable as part of select statement.

 Begin
    DECLARE @name nvarchar(max)
    select 
       @name = PolicyHolderName,
       PolicyHolderAddress 
    from Table
 END

The the above code can be corrected like below,

Begin
    DECLARE @name nvarchar(max)
    DECLARE @address varchar(100)
    select 
       @name = PolicyHolderName,
       @address = PolicyHolderAddress 
    from Table
END

So either remove the data-retrieval operation or add extra local variable. This will resolve the error.

What worked for me was to create a new report from scratch.

This done and the new report working, I will compare the 2 .rdl files in Visual Studio. These are in XML format and I am hoping a quick WindDiff or something would reveal what the issue was.

An initial look shows there are 700 lines of code or a bit more difference between both files, with the larger of the 2 being the faulty file. A cursory look at the TablixHeader tags didn't reveal anything obvious.

But in my case it was a corrupted .rdl file. This was originally copied from a working report so in the process of removing what wasn't re-used, this could have corrupted it. However, other reports where this same process was done, the headers could repeat when the correct settings were made in Properties.

Hope this helps. If you've got a complex report, this isn't the quick fix but it works.

Perhaps comparing known good XML files to faulty ones on your end would make a good forum post. I'll be trying that on my end.

How about:

<meta http-equiv="refresh" content="5;url=http://site.com/file.ext">

This way works on all browsers (i think) and let you put a message like: "If the download doesn't start in five seconds, click here."

If you need it to be with javascript.. well...

document.write('<meta http-equiv="refresh" content="5;url=http://site.com/file.ext">');

Regards

<script type="text/javascript">
    function clearThis(target){
        if(target.value=='[email protected]'){
        target.value= "";}
    }
    </script>

Is this really what your looking for?

My suggestion would be to run compaudit and then just fix permissions on the directories found by the audit. Make sure the identified directories do not have write permissions for group or other.

I wanted to install SQL server 2014 and same story happened. I had installed both VS2010 and VS2015 before. I tried all solutions where provided nothing worked.At last If you have new versions of VS like VS2015 or VS2017, uninstall VS2010 (if you really don't need it ).

If you want to have VS2010 on your system, install SQL server first and then install VS2010.When SQL server is installing it uses an instance of VS2010, if you have installed VS2010 before and that is an old version this error happens.

Since this topic is not close I'll post this answer, I hope this helps someone to understand why java does not allow multiple inheritance.

Consider the following class:

public class Abc{

    public void doSomething(){

    }

}

In this case the class Abc does not extends nothing right? Not so fast, this class implicit extends the class Object, base class that allow everything work in java. Everything is an object.

If you try to use the class above you'll see that your IDE allow you to use methods like: equals(Object o), toString(), etc, but you didn't declare those methods, they came from the base class Object

You could try:

public class Abc extends String{

    public void doSomething(){

    }

}

This is fine, because your class will not implicit extends Object but will extends String because you said it. Consider the following change:

public class Abc{

    public void doSomething(){

    }

    @Override
    public String toString(){
        return "hello";
    }

}

Now your class will always return "hello" if you call toString().

Now imagine the following class:

public class Flyer{

    public void makeFly(){

    }

}

public class Bird extends Abc, Flyer{

    public void doAnotherThing(){

    }

}

Again class Flyer implicit extends Object which has the method toString(), any class will have this method since they all extends Object indirectly, so, if you call toString() from Bird, which toString() java would have to use? From Abc or Flyer? This will happen with any class that try to extends two or more classes, to avoid this kind of "method collision" they built the idea of interface, basically you could think them as an abstract class that does not extends Object indirectly. Since they are abstract they will have to be implemented by a class, which is an object (you cannot instanciate an interface alone, they must be implemented by a class), so everything will continue to work fine.

To differ classes from interfaces, the keyword implements was reserved just for interfaces.

You could implement any interface you like in the same class since they does not extends anything by default (but you could create a interface that extends another interface, but again, the "father" interface would not extends Object"), so an interface is just an interface and they will not suffer from "methods signature colissions", if they do the compiler will throw a warning to you and you will just have to change the method signature to fix it (signature = method name + params + return type).

public interface Flyer{

    public void makeFly(); // <- method without implementation

}

public class Bird extends Abc implements Flyer{

    public void doAnotherThing(){

    }

    @Override
    public void makeFly(){ // <- implementation of Flyer interface

    }

    // Flyer does not have toString() method or any method from class Object, 
    // no method signature collision will happen here

}

This will change the background color according to the choice of user selected from the drop-down menu:

function changeBG() {_x000D_
  var selectedBGColor = document.getElementById("bgchoice").value;_x000D_
  document.body.style.backgroundColor = selectedBGColor;_x000D_
}

<select id="bgchoice" onchange="changeBG()">_x000D_
    <option></option>_x000D_
    <option value="red">Red</option>_x000D_
    <option value="ivory">Ivory</option>_x000D_
    <option value="pink">Pink</option>_x000D_
</select>

Its possible, but not directly.

In short, go to the search, use your regex, check "mark line" and click "Find all". It results in bookmarks for all those lines.

In the search menu there is a point "delete bookmarked lines" voila.

I found the answer here (the correct answer is the second one, not the accepted!): How to delete specific lines on Notepad++?

It is worth knowing that if you run out of usable disc space on your server partition or drive, that this will also cause MySQL to return this error. If you're sure it's not the actual number of users connected then the next step is to check that you have free space on your MySQL server drive/partition.

Edit January 2019:
This is true of MySQL 5.7 and 5.8 . I do not know for versions above this.

if not exist "%USERPROFILE%\.qgis-custom\" (
    mkdir "%USERPROFILE%\.qgis-custom" 2>nul
    if not errorlevel 1 (
        xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
    )
)

You have it almost done. The logic is correct, just some little changes.

This code checks for the existence of the folder (see the ending backslash, just to differentiate a folder from a file with the same name).

If it does not exist then it is created and creation status is checked. If a file with the same name exists or you have no rights to create the folder, it will fail.

If everyting is ok, files are copied.

All paths are quoted to avoid problems with spaces.

It can be simplified (just less code, it does not mean it is better). Another option is to always try to create the folder. If there are no errors, then copy the files

mkdir "%USERPROFILE%\.qgis-custom" 2>nul 
if not errorlevel 1 (
    xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
)

In both code samples, files are not copied if the folder is not being created during the script execution.

EDITED - As dbenham comments, the same code can be written as a single line

md "%USERPROFILE%\.qgis-custom" 2>nul && xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e

The code after the && will only be executed if the previous command does not set errorlevel. If mkdir fails, xcopy is not executed.

Added a new answer to display the code formatted:

The thing is that you were checking for document.referer, because you were in ff it was returning always true, then it was navigating to http://mysite.com. Try the following:

function backAway(){
    if (document.referrer) {
        //firefox, chrome, etc..
        i = 0;
    } else {
        // under ie
        i = 1;
    }
    if (history.length>i)
    {
        // there are items in history property
        history.back();
    } else {
        window.location = 'http://www.mysite.com/';
    }
    return false;
}

There's a much easier way to do this, using iconv - from the user notes, this seems to be what you want to do: characters transliteration

// PHP.net User notes
<?php
    $string = "?ABBASABAD";

    echo iconv('UTF-8', 'ISO-8859-1//TRANSLIT', $string);
    // output: [nothing, and you get a notice]

    echo iconv('UTF-8', 'ISO-8859-1//IGNORE', $string);
    // output: ABBSBD

    echo iconv('UTF-8', 'ISO-8859-1//TRANSLIT//IGNORE', $string);
    // output: ABBASABAD
    // Yay! That's what I wanted!
?>

Be very conscientious with your character encodings, so you are keeping the same encoding at all stages in the process - front end, form submission, encoding of the source files. Default encoding in PHP and in forms is ISO-8859-1, before PHP 5.4 where it changed to be UTF8 (finally!).

There's a couple of functions you can play around with for ideas. First is from CakePHP's inflector class, called slug:

public static function slug($string, $replacement = '_') {
    $quotedReplacement = preg_quote($replacement, '/');

    $merge = array(
        '/[^\s\p{Ll}\p{Lm}\p{Lo}\p{Lt}\p{Lu}\p{Nd}]/mu' => ' ',
        '/\\s+/' => $replacement,
        sprintf('/^[%s]+|[%s]+$/', $quotedReplacement, $quotedReplacement) => '',
    );

    $map = self::$_transliteration + $merge;
    return preg_replace(array_keys($map), array_values($map), $string);
}

It depends on a self::$_transliteration array which is similar to what you were doing in your question - you can see the source for inflector on github.

Another is a function I use personally, which comes from here.

function slugify($text,$strict = false) {
    $text = html_entity_decode($text, ENT_QUOTES, 'UTF-8');
    // replace non letter or digits by -
    $text = preg_replace('~[^\\pL\d.]+~u', '-', $text);

    // trim
    $text = trim($text, '-');
    setlocale(LC_CTYPE, 'en_GB.utf8');
    // transliterate
    if (function_exists('iconv')) {
        $text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);
    }

    // lowercase
    $text = strtolower($text);
    // remove unwanted characters
    $text = preg_replace('~[^-\w.]+~', '', $text);
    if (empty($text)) {
        return 'empty_$';
    }
    if ($strict) {
        $text = str_replace(".", "_", $text);
    }
    return $text;
}

What those functions do is transliterate and create 'slugs' from arbitrary text input, which is a very very useful thing to have in your toolchest when making web apps. Hope this helps!

An even simpler solution to the above:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <color android:color="@color/semitransparent_white" />
    </item>
    <item>
        <color android:color="@color/transparent" />
    </item>
</selector>

Save that in the drawable folder and you're good to go.

Here I am sharing the script, convert UTC timestamp to Indian timestamp:-

    // create a $utc object with the UTC timezone
    $IST = new DateTime('2016-12-12 12:12:12', new DateTimeZone('UTC'));

    // change the timezone of the object without changing it's time
    $IST->setTimezone(new DateTimeZone('Asia/Kolkata'));

    // format the datetime
   echo $IST->format('Y-m-d H:i:s T');

Try this on Debian/Ubuntu:

sudo apt-get install python-mechanize

The input may be string or integer.

num = 1000  #or num = '1000'  
sum(map(lambda x: x[1]*(2**x[0]), enumerate(map(int, str(num))[::-1])))

# 8

df=df.filter(df["columnname"]>='2020-01-13')

use the --expression option

grep searchterm myfile.csv | sed --expression='s/replaceme/withthis/g'

    for k := range mapEg {
        keys = append(keys, k)
    }

I'm also having the same issue with a very latest Tomcat server (7.0.40). It goes non-responsive once for a couple of days.

To see open connections, you may use:

sudo netstat -tonp | grep jsvc | grep --regexp="127.0.0.1:443" --regexp="127.0.0.1:80" | grep CLOSE_WAIT

As mentioned in this post, you may use /proc/sys/net/ipv4/tcp_keepalive_time to view the values. The value seems to be in seconds and defaults to 7200 (i.e. 2 hours).

To change them, you need to edit /etc/sysctl.conf.

Open/create `/etc/sysctl.conf`
Add `net.ipv4.tcp_keepalive_time = 120` and save the file
Invoke `sysctl -p /etc/sysctl.conf`
Verify using `cat /proc/sys/net/ipv4/tcp_keepalive_time`

No, unlike in a lot of other languages, XSLT variables cannot change their values after they are created. You can however, avoid extraneous code with a technique like this:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

  <xsl:variable name="mapping">
    <item key="1" v1="A" v2="B" />
    <item key="2" v1="X" v2="Y" />
  </xsl:variable>
  <xsl:variable name="mappingNode"
                select="document('')//xsl:variable[@name = 'mapping']" />

  <xsl:template match="....">
    <xsl:variable name="testVariable" select="'1'" />

    <xsl:variable name="values" select="$mappingNode/item[@key = $testVariable]" />

    <xsl:variable name="variable1" select="$values/@v1" />
    <xsl:variable name="variable2" select="$values/@v2" />
  </xsl:template>
</xsl:stylesheet>

In fact, once you've got the values variable, you may not even need separate variable1 and variable2 variables. You could just use $values/@v1 and $values/@v2 instead.

Random Key Generator

keyLength argument is the character length you want for the key

function keyGen(keyLength) {
    var i, key = "", characters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";

    var charactersLength = characters.length;

    for (i = 0; i < keyLength; i++) {
        key += characters.substr(Math.floor((Math.random() * charactersLength) + 1), 1);
    }

    return key;
}


keyGen(12)
"QEt9mYBiTpYD"

They are essentially the same but using provides alias templates which is quite useful. One good example I could find is as follows:

namespace std {
 template<typename T> using add_const_t = typename add_const<T>::type;
}

So, we can use std::add_const_t<T> instead of typename std::add_const<T>::type

As a general rule, you can use Database_Default collation so you don't need to figure out which one to use. However, I strongly suggest reading Simons Liew's excellent article Understanding the COLLATE DATABASE_DEFAULT clause in SQL Server

SELECT *
  FROM [FAEB].[dbo].[ExportaComisiones] AS f
  JOIN [zCredifiel].[dbo].[optPerson] AS p
  ON (p.vTreasuryId = f.RFC) COLLATE Database_Default

We cannot escape if-else ladder in order to compare a string with others. Even regular switch-case is also an if-else ladder (for integers) internally. We might only want to simulate the switch-case for string, but can never replace if-else ladder. The best of the algorithms for string comparison cannot escape from using strcmp function. Means to compare character by character until an unmatch is found. So using if-else ladder and strcmp are inevitable.

DEMO

And here are simplest macros to simulate the switch-case for strings.

#ifndef SWITCH_CASE_INIT
#define SWITCH_CASE_INIT
    #define SWITCH(X)   for (char* __switch_p__ = X, int __switch_next__=1 ; __switch_p__ ; __switch_p__=0, __switch_next__=1) { {
    #define CASE(X)         } if (!__switch_next__ || !(__switch_next__ = strcmp(__switch_p__, X))) {
    #define DEFAULT         } {
    #define END         }}
#endif

And you can use them as

char* str = "def";

SWITCH (str)
    CASE ("abc")
        printf ("in abc\n");
        break;
    CASE ("def")              // Notice: 'break;' statement missing so the control rolls through subsequent CASE's until DEFAULT 
        printf("in def\n");
    CASE ("ghi")
        printf ("in ghi\n");
    DEFAULT
        printf("in DEFAULT\n");
END

Output:

in def
in ghi
in DEFAULT

Below is nested SWITCH usage:

char* str = "def";
char* str1 = "xyz";

SWITCH (str)
    CASE ("abc")
        printf ("in abc\n");
        break;
    CASE ("def")                                
        printf("in def\n");
        SWITCH (str1)                           // <== Notice: Nested SWITCH
            CASE ("uvw")
                printf("in def => uvw\n");
                break;
            CASE ("xyz")
                printf("in def => xyz\n");
                break;
            DEFAULT
                printf("in def => DEFAULT\n");
        END
    CASE ("ghi")
        printf ("in ghi\n");
    DEFAULT
        printf("in DEFAULT\n");
END

Output:

in def
in def => xyz
in ghi
in DEFAULT

Here is reverse string SWITCH, where in you can use a variable (rather than a constant) in CASE clause:

char* str2 = "def";
char* str3 = "ghi";

SWITCH ("ghi")                      // <== Notice: Use of variables and reverse string SWITCH.
    CASE (str1)
        printf ("in str1\n");
        break;
    CASE (str2)                     
        printf ("in str2\n");
        break;
    CASE (str3)                     
        printf ("in str3\n");
        break;
    DEFAULT
        printf("in DEFAULT\n");
END

Output:

in str3

Automatically entering the password for the rsync command is difficult. My simple solution to avoid the problem is to mount the folder to be backed up. Then use a local rsync command to backup the mounted folder.

mount -t cifs //server/source/ /mnt/source-tmp -o username=Username,password=password
rsync -a /mnt/source-tmp /media/destination/
umount /mnt/source-tmp

Here's my hack (this is my root-level file, with a little redux mixed in there - though I'm not using react-router-redux):

const store = configureStore()
const customHistory = createBrowserHistory({
  basename: config.urlBasename || ''
})

ReactDOM.render(
  <Provider store={store}>
    <Router history={customHistory}>
      <Route component={({history}) => {
        window.appHistory = history
        return (
          <App />
        )
      }}/>
    </Router>
  </Provider>,
  document.getElementById('root')
)

I can then use window.appHistory.push() anywhere I want (for example, in my redux store functions/thunks/sagas, etc) I had hoped I could just use window.customHistory.push() but for some reason react-router never seemed to update even though the url changed. But this way I have the EXACT instance react-router uses. I don't love putting stuff in the global scope, and this is one of the few things I'd do that with. But it's better than any other alternative I've seen IMO.

Your understanding is correct. I wonder why you don't see any advantages in ContextLoaderListener. For example, you need to build a session factory (to manage database). This operation can take some time, so it's better to do it on startup. Of course you can do it with init servlets or something else, but the advantage of Spring's approach is that you make configuration without writing code.

let url = NSURL.URLWithString("http://live-wallpaper.net/iphone/img/app/i/p/iphone-4s-wallpapers-mobile-backgrounds-dark_2466f886de3472ef1fa968033f1da3e1_raw_1087fae1932cec8837695934b7eb1250_raw.jpg");

You need to add JQuery before adding bootstrap-

When using any form of Ajax, detailed documentation for the format of responses received from the CGI server seems to be lacking on the Web. Some entries here point out that newlines in returned text or json data must be escaped to prevent infinite loops (hangs) in JSON conversion (possibly created by throwing an uncaught exception), whether done automatically by jQuery or manually using Javascript system or library JSON parsing calls.

In each case where programmers post this problem, inadequate solutions are presented (most often replacing \n by \\n on the sending side) and the matter is dropped. Their inadequacy is revealed when passing string values that accidentally embed control escape sequences, such as Windows pathnames. An example is "C:\Chris\Roberts.php", which contains the control characters ^c and ^r, which can cause JSON conversion of the string {"file":"C:\Chris\Roberts.php"} to loop forever. One way of generating such values is deliberately to attempt to pass PHP warning and error messages from server to client, a reasonable idea.

By definition, Ajax uses HTTP connections behind the scenes. Such connections pass data using GET and POST, both of which require encoding sent data to avoid incorrect syntax, including control characters.

This gives enough of a hint to construct what seems to be a solution (it needs more testing): to use rawurlencode on the PHP (sending) side to encode the data, and unescape on the Javascript (receiving) side to decode the data. In some cases, you will apply these to entire text strings, in other cases you will apply them only to values inside JSON.

If this idea turns out to be correct, simple examples can be constructed to help programmers at all levels solve this problem once and for all.

equals() method is used to determine the equality of two objects.

as int value of 10 is always equal to 10. But this equals() method is about equality of two objects. When we say object, it will have properties. To decide about equality those properties are considered. It is not necessary that all properties must be taken into account to determine the equality and with respect to the class definition and context it can be decided. Then the equals() method can be overridden.

we should always override hashCode() method whenever we override equals() method. If not, what will happen? If we use hashtables in our application, it will not behave as expected. As the hashCode is used in determining the equality of values stored, it will not return the right corresponding value for a key.

Default implementation given is hashCode() method in Object class uses the internal address of the object and converts it into integer and returns it.

public class Tiger {
  private String color;
  private String stripePattern;
  private int height;

  @Override
  public boolean equals(Object object) {
    boolean result = false;
    if (object == null || object.getClass() != getClass()) {
      result = false;
    } else {
      Tiger tiger = (Tiger) object;
      if (this.color == tiger.getColor()
          && this.stripePattern == tiger.getStripePattern()) {
        result = true;
      }
    }
    return result;
  }

  // just omitted null checks
  @Override
  public int hashCode() {
    int hash = 3;
    hash = 7 * hash + this.color.hashCode();
    hash = 7 * hash + this.stripePattern.hashCode();
    return hash;
  }

  public static void main(String args[]) {
    Tiger bengalTiger1 = new Tiger("Yellow", "Dense", 3);
    Tiger bengalTiger2 = new Tiger("Yellow", "Dense", 2);
    Tiger siberianTiger = new Tiger("White", "Sparse", 4);
    System.out.println("bengalTiger1 and bengalTiger2: "
        + bengalTiger1.equals(bengalTiger2));
    System.out.println("bengalTiger1 and siberianTiger: "
        + bengalTiger1.equals(siberianTiger));

    System.out.println("bengalTiger1 hashCode: " + bengalTiger1.hashCode());
    System.out.println("bengalTiger2 hashCode: " + bengalTiger2.hashCode());
    System.out.println("siberianTiger hashCode: "
        + siberianTiger.hashCode());
  }

  public String getColor() {
    return color;
  }

  public String getStripePattern() {
    return stripePattern;
  }

  public Tiger(String color, String stripePattern, int height) {
    this.color = color;
    this.stripePattern = stripePattern;
    this.height = height;

  }
}

Example Code Output:

bengalTiger1 and bengalTiger2: true 
bengalTiger1 and siberianTiger: false 
bengalTiger1 hashCode: 1398212510 
bengalTiger2 hashCode: 1398212510 
siberianTiger hashCode: –1227465966

Let's say that you have a folder named "contollers".

In your app.js you can put this code:

console.log("Loading controllers....");
var controllers = {};

var controllers_path = process.cwd() + '/controllers'

fs.readdirSync(controllers_path).forEach(function (file) {
    if (file.indexOf('.js') != -1) {
        controllers[file.split('.')[0]] = require(controllers_path + '/' + file)
    }
});

console.log("Controllers loaded..............[ok]");

... and ...

router.get('/ping', controllers.ping.pinging);

in your controllers forlder you will have the file "ping.js" with this code:

exports.pinging = function(req, res, next){
    console.log("ping ...");
}

And this is it....

I came looking for the answer to the Swift 3 Data to String question and never got a good answer. After some fooling around I came up with this:

var testString = "This is a test string"
var somedata = testString.data(using: String.Encoding.utf8)
var backToString = String(data: somedata!, encoding: String.Encoding.utf8) as String!

You can transfer value from controller using ViewData[""].

ViewData["hdnFlag"] = userId;
return View();

Now, In you view.

@{
    var localVar = ViewData["hdnFlag"]
}
<input type="hidden" asp-for="@localVar" />

Hope this will help...

As Peter already pointed out:

git pull origin master will fetch all the changes from the remote's master branch and will merge it into your local.We generally don't use git pull origin/master.We can do the same thing by git merge origin/master.It will merge all the changes from "cached copy" of origin's master branch into your local branch.In my case git pull origin/master is throwing the error.

well in your onitemClick you will send the selected value like deal , and send it in your intent when opening new activity and in your new activity get the sent data and related to selected item will display your data

to get the name from the list

String item = yourData.get(position).getName(); 

to set data in intent

intent.putExtra("Key", item);

to get the data in second activity

getIntent().getExtras().getString("Key")

$("#edate").change(function(){

   var edate = new Date($('#edate').val());
   var sdate = new Date($('#sdate').val());
   
   days = (edate- sdate) / (1000 * 60 * 60 * 24);
   days=days+1;
   alert (days);
   $("#nod").val(days);
});

Do what Google is doing. Create a PHP file that sets the cookie on all 3 domains. Then on the domain where the theme is going to set, create a HTML file that would load the PHP file that sets cookie on the other 2 domains. Example:

<html>
   <head></head>
   <body>
      <p>Please wait.....</p>
      <img src="http://domain2.com/setcookie.php?theme=whateveryourthemehere" />
      <img src="http://domain3.com/setcookie.php?theme=whateveryourthemehere" />
   </body>
</html>

Then add an onload callback on body tag. The document will only load when the images completely load that is when cookies are set on the other 2 domains. Onload Callback :

<head>
   <script>
   function loadComplete(){
      window.location="http://domain1.com";//URL of domain1
   }
   </script>
</head>
<body onload="loadComplete()">

setcookie.php

We set the cookies on the other domains using a PHP file like this :

<?php
if(isset($_GET['theme'])){
   setcookie("theme", $_GET['theme'], time()+3600);
}
?>

Now cookies are set on the three domains.

Actually, the standard shell is Bourne shell (sh). /bin/sh on Linux is actually bash, but if you're aiming for cross-platform scripts, you're better off sticking to features of the original Bourne shell or writing it in something like perl.

for integer types

#include <string.h>    

int array1[10] = {0,1,2,3,4,5,6,7,8,9};
int array2[10];


memcpy(array2,array1,sizeof(array1)); // memcpy("destination","source","size")

Create a CustomAdapter and in that you have the getView() so there if you want to change the listview background color use this :

v.setBackgroundColor(Color.CYAN);

If you want to change the textColor then do this :

tv.setTextColor(Color.RED);

and for the textSize :

tv.setTextSize(20);

where 'v' is the listview and 'tv' is the textview

The org/hamcrest/SelfDescribing class is not on the run-time classpath.

You can also set a default value for the variable, so you don't need to use two "[", which amounts to two processes ("[" is actually a program) instead of one.

It goes by this syntax: ${VARIABLE:-default}.

The whole thing has to be thought in such a way that this "default" value is something distinct from a "valid" value/content.

If that's not possible for some reason you probably need to add a step like checking if there's a value at all, along the lines of "if [ -z $VARIABLE ] ; then echo "the variable needs to be filled"", or "if [ ! -z $VARIABLE ] ; then #everything is fine, proceed with the rest of the script".

I believe that I have the simplest answer yet using Spring Boot 1.4, included imports for the test class.:

public class SomeClass {  /// this goes in it's own file
//// fields go here
}

import org.junit.Before
import org.junit.Test
import org.junit.runner.RunWith
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest
import org.springframework.http.MediaType
import org.springframework.test.context.junit4.SpringRunner
import org.springframework.test.web.servlet.MockMvc

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.post
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status

@RunWith(SpringRunner.class)
@WebMvcTest(SomeController.class)
public class ControllerTest {

  @Autowired private MockMvc mvc;
  @Autowired private ObjectMapper mapper;

  private SomeClass someClass;  //this could be Autowired
                                //, initialized in the test method
                                //, or created in setup block
  @Before
  public void setup() {
    someClass = new SomeClass(); 
  }

  @Test
  public void postTest() {
    String json = mapper.writeValueAsString(someClass);
    mvc.perform(post("/someControllerUrl")
       .contentType(MediaType.APPLICATION_JSON)
       .content(json)
       .accept(MediaType.APPLICATION_JSON))
       .andExpect(status().isOk());
  }

}

Ok...Ok... Don't worry i am also ruined by this error and fatal and when i got it i was so serious even i was not giving an attention to other work, but i got it, Simply first of all copy this code and paste in your system variable Under path ...

C:\Program Files;C:\Winnt;C:\Winnt\System32;C:\Program Files\Java\jre6\bin\javaw.exe

Now copy the "jre" folder from your path like i have have "jre" under this path

            C:\Program Files\Java

and paste it in your eclipse folder means where your eclipse.exe file is placed. like i have my eclipse set up in this location

    F:\Softwares\LANGUAGES SOFTEARE\Android Setup\eclipse

So inside the eclipse Folder paste the "jre" FOLDER . If you have "jre6" then rename it as "jre"....and run your eclipse you will got the solution...

   //<<<<<<<<<<<<<<----------------------------->>>>>>>>>>>>>>>>>>>                 

OTHER SOLUTION: 2

If the problem could't solve with the above steps, then follow these steps

1. Copy the folder "jre" from your Java path like C:\Program Files\Java\jre6* etc, and paste it in your eclipse directory(Where is your eclipse available)
2. Go to eclipse.ini file , open it up.
3. Change the directory of your javaw.exe file like

-vmF:\Softwares\LANGUAGES SOFTEARE\Android Setup\eclipse Indigo version 32 Bit\jre\bin/javaw.exe

Now this time when you will start eclipse it will search for javaw.exe, so it will search the path in the eclipse.ini, as it is now in the same folder so, it will start the javaw.exe and it will start working.

If You still have any query you can ask it again, just go on my profile and find out my email id. because i love stack overflow forum, and it made me a programmer.*

I'm pretty sure you can't simply add on delete cascade to an existing foreign key constraint. You have to drop the constraint first, then add the correct version. In standard SQL, I believe the easiest way to do this is to

• start a transaction,
• drop the foreign key,
• add a foreign key with on delete cascade, and finally
• commit the transaction

Repeat for each foreign key you want to change.

But PostgreSQL has a non-standard extension that lets you use multiple constraint clauses in a single SQL statement. For example

alter table public.scores
drop constraint scores_gid_fkey,
add constraint scores_gid_fkey
   foreign key (gid)
   references games(gid)
   on delete cascade;

If you don't know the name of the foreign key constraint you want to drop, you can either look it up in pgAdminIII (just click the table name and look at the DDL, or expand the hierarchy until you see "Constraints"), or you can query the information schema.

select *
from information_schema.key_column_usage
where position_in_unique_constraint is not null

I made a procedure that execute a FOREACH with CURSOR for any table.

Example of use:

CREATE TABLE #A (I INT, J INT)
INSERT INTO #A VALUES (1, 2), (2, 3)
EXEC PRC_FOREACH
    #A --Table we want to do the FOREACH
    , 'SELECT @I, @J' --The execute command, each column becomes a variable in the same type, so DON'T USE SPACES IN NAMES
   --The third variable is the database, it's optional because a table in TEMPB or the DB of the proc will be discovered in code

The result is 2 selects for each row. The syntax of UPDATE and break the FOREACH are written in the hints.

This is the proc code:

CREATE PROC [dbo].[PRC_FOREACH] (@TBL VARCHAR(100) = NULL, @EXECUTE NVARCHAR(MAX)=NULL, @DB VARCHAR(100) = NULL) AS BEGIN

    --LOOP BETWEEN EACH TABLE LINE            

IF @TBL + @EXECUTE IS NULL BEGIN
    PRINT '@TBL: A TABLE TO MAKE OUT EACH LINE'
    PRINT '@EXECUTE: COMMAND TO BE PERFORMED ON EACH FOREACH TRANSACTION'
    PRINT '@DB: BANK WHERE THIS TABLE IS (IF NOT INFORMED IT WILL BE DB_NAME () OR TEMPDB)' + CHAR(13)
    PRINT 'ROW COLUMNS WILL VARIABLE WITH THE SAME NAME (COL_A = @COL_A)'
    PRINT 'THEREFORE THE COLUMNS CANT CONTAIN SPACES!' + CHAR(13)
    PRINT 'SYNTAX UPDATE:

UPDATE TABLE
SET COL = NEW_VALUE
WHERE CURRENT OF MY_CURSOR

CLOSE CURSOR (BEFORE ALL LINES):

IF 1 = 1 GOTO FIM_CURSOR'
    RETURN
END
SET @DB = ISNULL(@DB, CASE WHEN LEFT(@TBL, 1) = '#' THEN 'TEMPDB' ELSE DB_NAME() END)

    --Identifies the columns for the variables (DECLARE and INTO (Next cursor line))

    FROM [' + @DB + '].SYS.COLUMNS C WITH(NOLOCK)

    , @INTO = ''--Read the next line

That depends on the size of your repository and how you forked it.

If it's quite a big repository you may have wanted to manage it in a special way (e.g. drop history). Basically, you can get differences between current and upstream versions, commit them and then cherry pick back to master.

Try reading this one. It describes how to handle big Git repositories and how to upstream them with latest changes.

This is my Save Attachments script. You select all the messages that you want the attachments saved from, and it will save a copy there. It also adds text to the message body indicating where the attachment is saved. You could easily change the folder name to include the date, but you would need to make sure the folder existed before starting to save files.

Public Sub SaveAttachments()
Dim objOL As Outlook.Application
Dim objMsg As Outlook.MailItem 'Object
Dim objAttachments As Outlook.Attachments
Dim objSelection As Outlook.Selection
Dim i As Long
Dim lngCount As Long
Dim strFile As String
Dim strFolderpath As String
Dim strDeletedFiles As String

' Get the path to your My Documents folder
strFolderpath = CreateObject("WScript.Shell").SpecialFolders(16)
On Error Resume Next

' Instantiate an Outlook Application object.
Set objOL = CreateObject("Outlook.Application")

' Get the collection of selected objects.
Set objSelection = objOL.ActiveExplorer.Selection

' Set the Attachment folder.
strFolderpath = strFolderpath & "\Attachments\"

' Check each selected item for attachments. If attachments exist,
' save them to the strFolderPath folder and strip them from the item.
For Each objMsg In objSelection

    ' This code only strips attachments from mail items.
    ' If objMsg.class=olMail Then
    ' Get the Attachments collection of the item.
    Set objAttachments = objMsg.Attachments
    lngCount = objAttachments.Count
    strDeletedFiles = ""

    If lngCount > 0 Then

        ' We need to use a count down loop for removing items
        ' from a collection. Otherwise, the loop counter gets
        ' confused and only every other item is removed.

        For i = lngCount To 1 Step -1

            ' Save attachment before deleting from item.
            ' Get the file name.
            strFile = objAttachments.Item(i).FileName

            ' Combine with the path to the Temp folder.
            strFile = strFolderpath & strFile

            ' Save the attachment as a file.
            objAttachments.Item(i).SaveAsFile strFile

            ' Delete the attachment.
            objAttachments.Item(i).Delete

            'write the save as path to a string to add to the message
            'check for html and use html tags in link
            If objMsg.BodyFormat <> olFormatHTML Then

            End If

            'Use the MsgBox command to troubleshoot. Remove it from the final code.
            'MsgBox strDeletedFiles

        Else
            objMsg.HTMLBody = "<p>" & "The file(s) were saved to " & strDeletedFiles & "</p>" & objMsg.HTMLBody
        End If

Currently, it is evaluating to True because the variable has a value. There is a good example found here of what happens when you evaluate arbitrary types as a boolean.

In short, what you want to do is isolate the 'True' or 'False' string and run eval on it.

>>> eval('True')
True
>>> eval('False')
False

An improvement based on the post by Dishan TD (which removes the vertical margin as well):

  .slick-slide{
    margin-left:  15px;
    margin-right:  15px;
  }

  .slick-list {
    margin-left: -15px;
    margin-right: -15px;
    pointer-events: none;
  }

Note: the pointer-events was necessary in my case, to be able to click on the left arrow.

Implement in this way

String i="hi";
Intent i = new Intent(this, ActivityTwo.class);
//Create the bundle
Bundle b = new Bundle();
//Add your data to bundle
b.putString(“stuff”, i);
i.putExtras(b);
startActivity(i);

Begin that second activity, inside this class to utilize the Bundle values use this code

Bundle bundle = getIntent().getExtras();
String text= bundle.getString("stuff");

Every time you call itr2.next() you are getting a distinct value. Not the same value. You should only call this once in the loop.

Iterator<String> itr2 = keys.iterator();
    while(itr2.hasNext()){
        String v = itr2.next();
        System.out.println("Key: "+v+" ,value: "+m.get(v));
    }

log2j now has support to delete old logs.

Take a look at DefaultRolloverStrategy tag and at a snippet below.

It

• creates up to 10 archives on the same day,

• will parse the ${baseDir} directory that you define under the Properties tag at max depth of 2 with log filename matching "app-*.log.gz"

• delete logs older than 7 days but keep the most recent 5 logs if your most recent 5 logs are older than 7 days.

  <DefaultRolloverStrategy max="10">
    <Delete basePath="${baseDir}" maxDepth="2">
      <IfFileName glob="*/app-*.log.gz">
        <IfLastModified age="7d">
          <IfAny>
            <IfAccumulatedFileCount exceeds="5" />
          </IfAny>
        </IfLastModified>
      </IfFileName>
    </Delete>
  </DefaultRolloverStrategy>
  

A good debug option is if you set:

<Configuration status="trace">

and use testMode Option like this:

        <DefaultRolloverStrategy>
          <Delete basePath="${baseDir}" testMode="true">
            <IfFileName glob="*.log" />
            <IfLastModified age="7d" />
          </Delete>
        </DefaultRolloverStrategy>
        

You can see in console log what files would get deleted without deleting the files right away.

Something like...

Minutes.minutesBetween(getStart(), getEnd()).getMinutes();

I know this is well after the OP. One way you can go with that keeps the table storing the zipcode data as an unsigned INT but displayed with zeros is as follows.

select LPAD(cast(zipcode_int as char), 5, '0') as zipcode from table;

While this preserves the original data as INT and can save some space in storage you will be having the server perform the INT to CHAR conversion for you. This can be thrown into a view and the person who needs this data can be directed there vs the table itself.

If I understood it right you are doing an XMLHttpRequest to a different domain than your page is on. So the browser is blocking it as it usually allows a request in the same origin for security reasons. You need to do something different when you want to do a cross-domain request. A tutorial about how to achieve that is Using CORS.

When you are using postman they are not restricted by this policy. Quoted from Cross-Origin XMLHttpRequest:

Regular web pages can use the XMLHttpRequest object to send and receive data from remote servers, but they're limited by the same origin policy. Extensions aren't so limited. An extension can talk to remote servers outside of its origin, as long as it first requests cross-origin permissions.

You can use either sbt or maven to compile spark programs. Simply add the spark as dependency to maven

<repository>
      <id>Spark repository</id>
      <url>http://www.sparkjava.com/nexus/content/repositories/spark/</url>
</repository>

And then the dependency:

<dependency>
      <groupId>spark</groupId>
      <artifactId>spark</artifactId>
      <version>1.2.0</version>
</dependency>

In terms of running a file with spark commands: you can simply do this:

echo"
   import org.apache.spark.sql.*
   ssc = new SQLContext(sc)
   ssc.sql("select * from mytable").collect
" > spark.input

Now run the commands script:

cat spark.input | spark-shell

the best way

map.off();
map.remove();

You should add map.off(), it also works faster, and does not cause problems with the events

Three ways to align img in the center of its parent.

1. img is an inline element, text-center aligns inline elements in the center of its container should the container be a block element.

<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.1/css/bootstrap.css" rel="stylesheet"/>_x000D_
<div class="container mt-5">_x000D_
  <div class="row">_x000D_
    <div class="col text-center">_x000D_
      <img src="https://upload.wikimedia.org/wikipedia/en/8/80/Wikipedia-logo-v2.svg" alt="" class="img-fluid">_x000D_
    </div>_x000D_
  </div>_x000D_
</div>

2. mx-auto centers block elements. In order to so, change display of the img from inline to block with d-block class.

<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.1/css/bootstrap.css" rel="stylesheet"/>_x000D_
<div class="container mt-5">_x000D_
  <div class="row">_x000D_
    <div class="col">_x000D_
      <img src="https://upload.wikimedia.org/wikipedia/en/8/80/Wikipedia-logo-v2.svg" alt="" class="img-fluid d-block mx-auto">_x000D_
    </div>_x000D_
  </div>_x000D_
</div>

3. Use d-flex and justify-content-center on its parent.

<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.1/css/bootstrap.css" rel="stylesheet"/>_x000D_
<div class="container mt-5">_x000D_
  <div class="row">_x000D_
    <div class="col d-flex justify-content-center">_x000D_
      <img src="https://upload.wikimedia.org/wikipedia/en/8/80/Wikipedia-logo-v2.svg" alt="" class="img-fluid">_x000D_
    </div>_x000D_
  </div>_x000D_
</div>

When I align elements in center I use the bootstrap class text-center:

<div class="text-center">Centered content goes here</div>

I wrote a plugin sometime back for attrchange listener which basically adds a listener function on attribute change. Even though I say it as a plugin, actually it is a simple function written as a jQuery plugin.. so if you want.. strip off the plugin specfic code and use the core functions.

Note: This code doesn't use polling

check out this simple demo http://jsfiddle.net/aD49d/

$(function () {
    var prevHeight = $('#test').height();
    $('#test').attrchange({
        callback: function (e) {
            var curHeight = $(this).height();            
            if (prevHeight !== curHeight) {
               $('#logger').text('height changed from ' + prevHeight + ' to ' + curHeight);

                prevHeight = curHeight;
            }            
        }
    }).resizable();
});

According to the docs you can set the parse_mode field to:

• MarkdownV2
• HTML

Markdown still works but it's now considered a legacy mode.

You can pass the parse_mode parameter like this:

https://api.telegram.org/bot[yourBotKey]/sendMessage?chat_id=[yourChatId]&parse_mode=MarkdownV2&text=[yourMessage]

For bold and italic using MarkdownV2:

*bold text*
_italic text_

And for HTML:

<b>bold</b> or <strong>bold</strong>
<i>italic</I> or <em>italic</em>

Make sure to encode your query-string parameters regardless the format you pick. For example:

• Java/Scala (see note on spaces):

val message = "*bold text*";
val encodedMsg = URLEncoder.encode(message, "UTF-8");

• Javascript (ref)

var message = "*bold text*"
var encodedMsg = encodeURIComponent(message)

• PHP (ref)

$message = "*bold text*";
$encodedMsg = urlencode($message);

This Bootply example seems like a much better option. Only thing is that the labels are a little too high so I added padding-top:5px to center them with my inputs.

File format not recognized You need to properly format your file. That means using the right colors and fonts for your code. See the specific documentations for each compiler as these colors vary between compiler ;)

is just going to look for a div with class="outer inner", is that correct?

No, '.outer .inner' will look for all elements with the .inner class that also have an element with the .outer class as an ancestor. '.outer.inner' (no space) would give the results you're thinking of.

'.outer > .inner' will look for immediate children of an element with the .outer class for elements with the .inner class.

Both '.outer .inner' and '.outer > .inner' should work for your example, although the selectors are fundamentally different and you should be wary of this.

CREATE TABLE #CountMe (Col1 char(1));

INSERT INTO #CountMe VALUES ('A');
INSERT INTO #CountMe VALUES ('B');
INSERT INTO #CountMe VALUES ('A');
INSERT INTO #CountMe VALUES ('B');

SELECT
    COUNT(CASE WHEN Col1 = 'A' THEN 1 END) AS CountWithoutElse,
    COUNT(CASE WHEN Col1 = 'A' THEN 1 ELSE NULL END) AS CountWithElseNull,
    COUNT(CASE WHEN Col1 = 'A' THEN 1 ELSE 0 END) AS CountWithElseZero
FROM #CountMe;

Just spicing up the shell script above to delete older files but with logging and calculation of elapsed time

#!/bin/bash

path="/data/backuplog/"
timestamp=$(date +%Y%m%d_%H%M%S)    
filename=log_$timestamp.txt    
log=$path$filename
days=7

START_TIME=$(date +%s)

find $path -maxdepth 1 -name "*.txt"  -type f -mtime +$days  -print -delete >> $log

echo "Backup:: Script Start -- $(date +%Y%m%d_%H%M)" >> $log


... code for backup ...or any other operation .... >> $log


END_TIME=$(date +%s)

ELAPSED_TIME=$(( $END_TIME - $START_TIME ))


echo "Backup :: Script End -- $(date +%Y%m%d_%H%M)" >> $log
echo "Elapsed Time ::  $(date -d 00:00:$ELAPSED_TIME +%Hh:%Mm:%Ss) "  >> $log

The code adds a few things.

• log files named with a timestamp
• log folder specified
• find looks for *.txt files only in the log folder
• type f ensures you only deletes files
• maxdepth 1 ensures you dont enter subfolders
• log files older than 7 days are deleted ( assuming this is for a backup log)
• notes the start / end time
• calculates the elapsed time for the backup operation...

Note: to test the code, just use -print instead of -print -delete. But do check your path carefully though.

Note: Do ensure your server time is set correctly via date - setup timezone/ntp correctly . Additionally check file times with 'stat filename'

Note: mtime can be replaced with mmin for better control as mtime discards all fractions (older than 2 days (+2 days) actually means 3 days ) when it deals with getting the timestamps of files in the context of days

-mtime +$days  --->  -mmin  +$((60*24*$days))

// This was my example that I used to automatically resize every inserted photo to 100 by 50 pixel and image format to jpeg hope this helps too

    $target_filename = $_FILES['photo']['tmp_name'];
    $fn = $_FILES['photo']['tmp_name'];
    $size = getimagesize( $fn );
    $ratio = $size[0]/$size[1]; // width/height
    if( $ratio > 1) {
        $width = $maxDimW;
        $height = $maxDimH/$ratio;
    } else {
        $width = $maxDimW*$ratio;
        $height = $maxDimH;
    }

    $dst = imagecreatetruecolor( $width, $height );
    imagecopyresampled($dst, $src, 0, 0, 0, 0, $width, $height, $size[0], $size[1] );

    imagejpeg($dst, $target_filename); // adjust format as needed

Here is a solution I use very often. When you have a large data set with tons of columns, you definitely do not want to manually rearrange all the columns.

What you can and, most likely, want to do is to just order the first a few columns that you frequently use, and let all other columns just be themselves. This is a common approach in R. df %>%select(one, two, three, everything())

So you can first manually type the columns that you want to order and to be positioned before all the other columns in a list cols_to_order.

Then you construct a list for new columns by combining the rest of the columns:

new_columns = cols_to_order + (frame.columns.drop(cols_to_order).tolist())

After this, you can use the new_columns as other solutions suggested.

import pandas as pd
frame = pd.DataFrame({
    'one thing': [1, 2, 3, 4],
    'other thing': ['a', 'e', 'i', 'o'],
    'more things': ['a', 'e', 'i', 'o'],
    'second thing': [0.1, 0.2, 1, 2],
})

cols_to_order = ['one thing', 'second thing']
new_columns = cols_to_order + (frame.columns.drop(cols_to_order).tolist())
frame = frame[new_columns]

   one thing  second thing other thing more things
0          1           0.1           a           a
1          2           0.2           e           e
2          3           1.0           i           i
3          4           2.0           o           o

you can always make your own RPM:

http://www.grenadepod.com/2009/12/26/building-python-2-6-4-rpm-for-centos-5-4/

alternatively in c or c++ after including stdio.h

char d=(char)(7);
printf("%c\n",d);

(char)7 is called the bell character.

The value of a field can not be null, it's always a string value.

The code will check if the string value is the string "NULL". You want to check if it's an empty string instead:

if ($('#person_data[document_type]').val() != ''){}

or:

if ($('#person_data[document_type]').val().length != 0){}

If you want to check if the element exist at all, you should do that before calling val:

var $d = $('#person_data[document_type]');
if ($d.length != 0) {
  if ($d.val().length != 0 ) {...}
}

typeof(AbstractDataExport).Assembly tells you an assembly your types are located in (assuming all are in the same).

assembly.GetTypes() gives you all types in that assembly or assembly.GetExportedTypes() gives you types that are public.

Iterating through the types and using type.IsAssignableFrom() gives you whether the type is derived.

Updated for iOS 8.0

Since iOS 8.0, you will need to use UIAlertController as the following:

-(void)alertMessage:(NSString*)message
{
    UIAlertController* alert = [UIAlertController
          alertControllerWithTitle:@"Alert"
          message:message
          preferredStyle:UIAlertControllerStyleAlert];

    UIAlertAction* defaultAction = [UIAlertAction 
          actionWithTitle:@"OK" style:UIAlertActionStyleDefault
         handler:^(UIAlertAction * action) {}];

    [alert addAction:defaultAction];
    [self presentViewController:alert animated:YES completion:nil];
}

Where self in my example is a UIViewController, which implements "presentViewController" method for a popup.

System.Windows.Forms.ToolTip ToolTip1 = new System.Windows.Forms.ToolTip();
ToolTip1.SetToolTip( Label1, "Label for Label1");

I got this resolved in angular with (click) = "someFuncionName()" in the .html file for the specific component.

You can try the following:

private void button1_Click(object sender, EventArgs e)
    {
        OpenFileDialog fDialog = new OpenFileDialog();
        fDialog.Title = "Select file to be upload";
        fDialog.Filter = "All Files|*.*";
        //  fDialog.Filter = "PDF Files|*.pdf";
        if (fDialog.ShowDialog() == DialogResult.OK)
        {
            textBox1.Text = fDialog.FileName.ToString();
        }
    }

Marker already has unique id

marker.__gm_id

The quick and dirty method is as follows:

cat ip_addresses | sort -n | uniq -c

If you need to use the values in bash you can assign the whole command to a bash variable and then loop through the results.

PS

If the sort command is omitted, you will not get the correct results as uniq only looks at successive identical lines.

The other answers are just fine, but I wanted to point out one other peripheral thing: Arrays are ordered, whereas Hashes are not in 1.8. (In Ruby 1.9, Hashes are ordered by insertion order of keys.) So it wouldn't make sense prior to 1.9 to iterate over a Hash in the same way/sequence as Arrays, which have always had a definite ordering. I don't know what the default order is for PHP associative arrays (apparently my google fu isn't strong enough to figure that out, either), but I don't know how you can consider regular PHP arrays and PHP associative arrays to be "the same" in this context, since the order for associative arrays seems undefined.

As such, the Ruby way seems more clear and intuitive to me. :)

Here is the code to check whether value is present or not.

If Trim(textbox1.text) <> "" Then
     'Your code goes here
Else
     'Nothing
End If

I think this will help.

It will be something like that:

SELECT OrderID, Quantity,
CASE
    WHEN Quantity > 30 THEN "The quantity is greater than 30"
    WHEN Quantity = 30 THEN "The quantity is 30"
    ELSE "The quantity is under 30"
END AS QuantityText
FROM OrderDetails;

Just to add to the accepted answer, as all the answers seem to talk about android.graphics.Color only: what if the color I want is defined in res/values/colors.xml?

For example, consider Material Design colors defined in colors.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="md_blue_500">#2196F3</color>
</resources>

(android_material_design_colours.xml is your best friend)

Then use ContextCompat.getColor(getContext(), R.color.md_blue_500) where you would use Color.BLUE, so that:

wordtoSpan.setSpan(new ForegroundColorSpan(Color.BLUE), 15, 30, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

becomes:

wordtoSpan.setSpan(new ForegroundColorSpan(ContextCompat.getColor(getContext(), R.color.md_blue_500)), 15, 30, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

Where I found that:

• Working with spans in Android – Michael Spitsin – Medium

The other methods are great but they don't preserve any prototype functions attached to init. To get around that you can do the following (inspired by the post from Nick Craver).

(function () {
    var old_prototype = init.prototype;
    var old_init = init;
    init = function () {
        old_init.apply(this, arguments);
        // Do something extra
    };
    init.prototype = old_prototype;
}) ();

Sometimes you will get lots of compiler outputs with many warnings and no line of output that says "error: you did something wrong here" but there was still an error. An example of this is a missing header file - the compiler says something like "no such file" but not "error: no such file", then it exits with non-zero exit code some time later (perhaps after many more warnings). Make will bomb out with an error message in these cases!

hi i put this task into a behavior. so you just have to add somthing like this to your textbox

<i:Interaction.Behaviors>
         <Behaviors:TextBoxWatermarkBehavior Label="Test Watermark" LabelStyle="{StaticResource StyleWatermarkLabel}"/>
</i:Interaction.Behaviors>

you can find my blog post here

You can remove that configuration with:

git config --global --unset core.gitproxy

I don't think the scrollTop is a valid property. If you want to animate scrolling, try the scrollTo plugin for jquery

first,i used "localhost:port" format met this error.then I changed the address to "ip:port" format and the problem solved.

Instead of using log4net which is an external library I have created my own simple class, highly customizable and easy to use (edit YOURNAMESPACEHERE with the namespace that you need).

CONSOLE APP

using System;
using System.IO;

namespace YOURNAMESPACEHERE
{
    enum LogEvent
    {
        Info = 0,
        Success = 1,
        Warning = 2,
        Error = 3
    }

    internal static class Log
    {
        private static readonly string LogSession = DateTime.Now.ToLocalTime().ToString("ddMMyyyy_HHmmss");
        private static readonly string LogPath = AppDomain.CurrentDomain.BaseDirectory + "logs";

        internal static void Write(LogEvent Level, string Message, bool ShowConsole = true, bool WritelogFile = true)
        {
            string Event = string.Empty;
            ConsoleColor ColorEvent = Console.ForegroundColor;

            switch (Level)
            {
                case LogEvent.Info:
                    Event = "INFO";
                    ColorEvent = ConsoleColor.White;
                    break;
                case LogEvent.Success:
                    Event = "SUCCESS";
                    ColorEvent = ConsoleColor.Green;
                    break;
                case LogEvent.Warning:
                    Event = "WARNING";
                    ColorEvent = ConsoleColor.Yellow;
                    break;
                case LogEvent.Error:
                    Event = "ERROR";
                    ColorEvent = ConsoleColor.Red;
                    break;
            }

            if (ShowConsole)
            {
                Console.ForegroundColor = ColorEvent;
                Console.WriteLine(" [{0}] => {1}", DateTime.Now.ToString("HH:mm:ss"), Message);
                Console.ResetColor();
            }

            if (WritelogFile)
            {
                if (!Directory.Exists(LogPath))
                    Directory.CreateDirectory(LogPath);

                File.AppendAllText(LogPath + @"\" + LogSession + ".log", string.Format("[{0}] => {1}: {2}\n", DateTime.Now.ToString("HH:mm:ss"), Event, Message));
            }
        }
    }
}

NO CONSOLE APP (ONLY LOG)

using System;
using System.IO;

namespace YOURNAMESPACEHERE
{
    enum LogEvent
    {
        Info = 0,
        Success = 1,
        Warning = 2,
        Error = 3
    }

internal static class Log
{
    private static readonly string LogSession = DateTime.Now.ToLocalTime().ToString("ddMMyyyy_HHmmss");
    private static readonly string LogPath = AppDomain.CurrentDomain.BaseDirectory + "logs";

    internal static void Write(LogEvent Level, string Message)
    {
        string Event = string.Empty;

        switch (Level)
        {
            case LogEvent.Info:
                Event = "INFO";
                break;
            case LogEvent.Success:
                Event = "SUCCESS";
                break;
            case LogEvent.Warning:
                Event = "WARNING";
                break;
            case LogEvent.Error:
                Event = "ERROR";
                break;
        }

        if (!Directory.Exists(LogPath))
            Directory.CreateDirectory(LogPath);

        File.AppendAllText(LogPath + @"\" + LogSession + ".log", string.Format("[{0}] => {1}: {2}\n", DateTime.Now.ToString("HH:mm:ss"), Event, Message));
    }
}

Usage:

CONSOLE APP

Log.Write(LogEvent.Info, "Test message"); // It will print an info in your console, also will save a copy of this print in a .log file.
Log.Write(LogEvent.Warning, "Test message", false); // It will save the print as warning only in your .log file.
Log.Write(LogEvent.Error, "Test message", true, false); // It will print an error only in your console.

NO CONSOLE APP (ONLY LOG)

Log.Write(LogEvent.Info, "Test message"); // It will print an info in your .log file.

For Encryption

  def encrypt(my_key=KEY, my_iv=IV, my_plain_text=PLAIN_TEXT): 

       key = binascii.unhexlify('ce975de9294067470d1684442555767fcb007c5a3b89927714e449c3f66cb2a4')
       iv = binascii.unhexlify('9aaecfcf7e82abb8118d8e567d42ee86')

       padder = PKCS7Padder()
       padded_text = padder.encode(my_plain_text)

      encryptor = AES.new(key, AES.MODE_CBC, iv, segment_size=128)  # Initialize encryptor
      result = encryptor.encrypt(padded_text)  

     return {
         "plain": my_plain_text,
         "key": binascii.hexlify(key),
         "iv": binascii.hexlify(iv),
         "ciphertext": result
}

Here's the script, rewritten to use the suggestions above and a change to your no-cache method.

<?php
// Simpler way of making sure all no-cache headers get sent
// and understood by all browsers, including IE.
session_cache_limiter('nocache');
header('Expires: ' . gmdate('r', 0));

header('Content-type: application/json');

// set to return response=error
$arr = array ('response'=>'error','comment'=>'test comment here');
echo json_encode($arr);
?>

//the script above returns this:
{"response":"error","comment":"test comment here"}

<script type="text/javascript">
$.ajax({
    type: "POST",
    url: "process.php",
    data: dataString,
    dataType: "json",
    success: function (data) {
        if (data.response == 'captcha') {
            alert('captcha');
        } else if (data.response == 'success') {
            alert('success');
        } else {
            alert('sorry there was an error');
        }
    }

}); // Semi-colons after all declarations, IE is picky on these things.
</script>

The main issue here was that you had a typo in the JSON you were returning ("resonse" instead of "response". This meant that you were looking for the wrong property in the JavaScript code. One way of catching these problems in the future is to console.log the value of data and make sure the property you are looking for is there.

Learning how to use the Chrome debugger tools (or similar tools in Firefox/Safari/Opera/etc.) will also be invaluable.

This should get your sorted:

• Highlight from the end of the first line, to the very beginning of the third line.
• Use the Ctrl + H to bring up the 'Find and Replace' window.
• The highlighed region will already be plased in the 'Find' textbox.
• Replace with: \r\n
• 'Replace All' will then remove all the additional line spaces not required.

Here's how it should look:

Hmmm... I would almost swear that this worked for the original Bourne shell, but don't have access to a running copy just now to check.

There is, however, a very trivial workaround to the problem.

Change the first line of the script from:

#!/bin/bash

to

#!/bin/ksh

Et voila! A read at the end of a pipeline works just fine, assuming you have the Korn shell installed.

in the graphical layout, you can choose the theme on the toolbar. (the one that looks like a star).

choose the NoTitleBar and have fun.

Use something like header( 'Location: /my-other-page.html' ); to redirect. You can't have sent any other data on the page before you do this though.

I believe all relevant solutions have been provided but here is a subtle situatuion: know that if you don't close and open your terminal again you will not see the effect.

Close your terminal and open then type in your terminal

yarn --version

If anyone still has problem, this is my code.

I have a custom view which is square (width = height) and I want to assign a character to it. onDraw() shows how to get height of character, although I'm not using it. Character will be displayed in the middle of view.

public class SideBarPointer extends View {

    private static final String TAG = "SideBarPointer";

    private Context context;
    private String label = "";
    private int width;
    private int height;

    public SideBarPointer(Context context) {
        super(context);
        this.context = context;
        init();
    }

    public SideBarPointer(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.context = context;
        init();
    }

    public SideBarPointer(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        this.context = context;
        init();
    }

    private void init() {
//        setBackgroundColor(0x64FF0000);
    }

    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec){
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        height = this.getMeasuredHeight();
        width = this.getMeasuredWidth();

        setMeasuredDimension(width, width);
    }

    protected void onDraw(Canvas canvas) {
        float mDensity = context.getResources().getDisplayMetrics().density;
        float mScaledDensity = context.getResources().getDisplayMetrics().scaledDensity;

        Paint previewPaint = new Paint();
        previewPaint.setColor(0x0C2727);
        previewPaint.setAlpha(200);
        previewPaint.setAntiAlias(true);

        Paint previewTextPaint = new Paint();
        previewTextPaint.setColor(Color.WHITE);
        previewTextPaint.setAntiAlias(true);
        previewTextPaint.setTextSize(90 * mScaledDensity);
        previewTextPaint.setShadowLayer(5, 1, 2, Color.argb(255, 87, 87, 87));

        float previewTextWidth = previewTextPaint.measureText(label);
//        float previewTextHeight = previewTextPaint.descent() - previewTextPaint.ascent();
        RectF previewRect = new RectF(0, 0, width, width);

        canvas.drawRoundRect(previewRect, 5 * mDensity, 5 * mDensity, previewPaint);
        canvas.drawText(label, (width - previewTextWidth)/2, previewRect.top - previewTextPaint.ascent(), previewTextPaint);

    }

    public void setLabel(String label) {
        this.label = label;

        this.invalidate();
    }
}

Update: You can now just right click

Right click > Save as in the Console panel to save the logged messages to a file.

Original Answer:

You can use this devtools snippet shown below to create a console.save method. It creates a FileBlob from the input, and then automatically downloads it.

(function(console){

console.save = function(data, filename){

    if(!data) {
        console.error('Console.save: No data')
        return;
    }

    if(!filename) filename = 'console.json'

    if(typeof data === "object"){
        data = JSON.stringify(data, undefined, 4)
    }

    var blob = new Blob([data], {type: 'text/json'}),
        e    = document.createEvent('MouseEvents'),
        a    = document.createElement('a')

    a.download = filename
    a.href = window.URL.createObjectURL(blob)
    a.dataset.downloadurl =  ['text/json', a.download, a.href].join(':')
    e.initMouseEvent('click', true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null)
    a.dispatchEvent(e)
 }
})(console)

Analogous to @Resh32, but without the need to use the USE statement:

SELECT TABLE_NAME,
       COLUMN_NAME,
       CONSTRAINT_NAME,
       REFERENCED_TABLE_NAME,
       REFERENCED_COLUMN_NAME
FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE TABLE_SCHEMA = "database_name" 
      AND TABLE_NAME = "table_name" 
      AND REFERENCED_COLUMN_NAME IS NOT NULL;

Useful, e.g. using the ORM.

Try for loops:

var numbers = [1, 2, 3, 4, 5];

for (var i=0;i<numbers.length;i++){
   $('<option/>').val(numbers[i]).html(numbers[i]).appendTo('#items');
}

Much better approach:

var numbers = [1, 2, 3, 4, 5];
var option = '';
for (var i=0;i<numbers.length;i++){
   option += '<option value="'+ numbers[i] + '">' + numbers[i] + '</option>';
}
$('#items').append(option);

 <item name="android:statusBarColor" tools:targetApi="lollipop">@android:color/transparent</item>
            <!--<item name="android:windowLightStatusBar" tools:targetApi="m">true</item>-->

Dont use windowLightStatusBar use instead statusBarColor = @android:color/transparent

What's the "largest" site that's built on Django today? (I measure size mostly by user traffic)

In the US, it was Mahalo. I'm told they handle roughly 10 million uniques a month. Now, in 2019, Mahalo is powered by Ruby on Rails.

Abroad, the Globo network (a network of news, sports, and entertainment sites in Brazil); Alexa ranks them in to top 100 globally (around 80th currently).

Other notable Django users include PBS, National Geographic, Discovery, NASA (actually a number of different divisions within NASA), and the Library of Congress.

Can Django deal with 100k users daily, each visiting the site for a couple of hours?

Yes -- but only if you've written your application right, and if you've got enough hardware. Django's not a magic bullet.

Could a site like StackOverflow run on Django?

Yes (but see above).

Technology-wise, easily: see soclone for one attempt. Traffic-wise, compete pegs StackOverflow at under 1 million uniques per month. I can name at least dozen Django sites with more traffic than SO.

Add a span with the style="float: right" element inside the h1 element. So you can add a "goto top of the page" link, with a unicode arrow link button.

<h1 id="myAnchor">Headline Text
<span style="float: right"><a href="#top" aria-hidden="true">?</a></span>
</h1>

You can use exec for that:

>>> foo = "bar"
>>> exec(foo + " = 'something else'")
>>> print bar
something else
>>> 

For more complex tasks there is expect ( http://en.wikipedia.org/wiki/Expect ). It basically simulates a user, you can code a script how to react to specific program outputs and related stuff.

This also works in cases like ssh that prohibits piping passwords to it.

The javaw.exe command is identical to java.exe, except that with javaw.exe there is no associated console window

There could be many reason why document.getElementById doesn't work

• You have an invalid ID

  ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods ("."). (resource: What are valid values for the id attribute in HTML?)

• you used some id that you already used as <meta> name in your header (e.g. copyright, author... ) it looks weird but happened to me: if your 're using IE take a look at (resource: http://www.phpied.com/getelementbyid-description-in-ie/)

• you're targeting an element inside a frame or iframe. In this case if the iframe loads a page within the same domain of the parent you should target the contentdocument before looking for the element (resource: Calling a specific id inside a frame)

• you're simply looking to an element when the node is not effectively loaded in the DOM, or maybe it's a simple misspelling

I doubt you used same ID twice or more: in that case document.getElementById should return at least the first element

I was not actually able to render an image without borders or axis data based on any of the code snippets here (even the one accepted at the answer). After digging through some API documentation, I landed on this code to render my image

plt.axis('off')
plt.tick_params(axis='both', left='off', top='off', right='off', bottom='off', labelleft='off', labeltop='off', labelright='off', labelbottom='off')
plt.savefig('foo.png', dpi=100, bbox_inches='tight', pad_inches=0.0)

I used the tick_params call to basically shut down any extra information that might be rendered and I have a perfect graph in my output file.

Adding to the solutions of others, I'd like to suggest using the plotly package for R, as this has worked well for me.

Below, I'm using the reformatted dataset suggested above, from xyz-tripplets to axis vectors x and y and a matrix z:

x <- 1:5/10
y <- 1:5
z <- x %o% y
z <- z + .2*z*runif(25) - .1*z

library(plotly)
plot_ly(x=x,y=y,z=z, type="surface")

The rendered surface can be rotated and scaled using the mouse. This works fairly well in RStudio.

You can also try it with the built-in volcano dataset from R:

plot_ly(z=volcano, type="surface")

That way you haven't installed pip, you installed just the easy_install i.e. setuptools.

First you should remove all the packages you installed with easy_install using (see uninstall):

easy_install -m PackageName

This includes pip if you installed it using easy_install pip.

After this you remove the setuptools following the instructions from here:

If setuptools package is found in your global site-packages directory, you may safely remove the following file/directory:

setuptools-*.egg

If setuptools is installed in some other location such as the user site directory (eg: ~/.local, ~/Library/Python or %APPDATA%), then you may safely remove the following files:

pkg_resources.py
easy_install.py
setuptools/
setuptools-*.egg-info/

Alt + Shift + o
Will solve your problem and agree with @Korhan Ozturk as well :)

This is known as Toggle Mark occurrence (Alt + Shift + O), Means will highlight all occurrence of focused variable. Same thing can be achieved from tool bar as follows

In same tool bar there is another switch if you turn that on you will see complete path for opened file, That is Breadcrumb

there are some more very useful switches like word wrap, Show white Characters just after toggle mark occurrence

I know this is a very old question. Just posting this here as I solved this problem using FlexBox. Here is the solution

#container {
  height: 100%;
  width: 100%;
  display: flex;
}
#leftThing {
  width: 25%;
  background-color: blue;
}
#content {
  width: 50%;
  background-color: green;
}
#rightThing {
  width: 25%;
  background-color: yellow;
}

<div id="container">

  <div id="leftThing">
    Left Side Menu
  </div>

  <div id="content">
    Random Content
  </div>

  <div id="rightThing">
    Right Side Menu
  </div>

</div>

Just had to add display:flex to the container! No floats required.

To allow DMARC checks for SPF to pass and also be aligned when using sendmail, make sure you are setting the envelope sender address (-f or -r parameter) to something that matches the domain in the From: header address.

With PHP:

Using PHP's built-in mail() function without setting the 5th paramater will cause DMARC SPF checks to be unaligned if not done correctly. By default, sendmail will send the email with the webserver's user as the RFC5321.MailFrom / Return Path header.

For example, say you are hosting your website domain.com on the host.com web server. If you do not set the additional parameters parameter:

mail($to,$subject,$message,$headers); // Wrong way

The email recipient will receive an email with the following mail headers:

Return-Path: <[email protected]>
From: <[email protected]>

Even though this passes SPF checks, it will be unaligned (since domain.com and host.com do not match), which means that DMARC SPF check will fail as unaligned.

Instead, you must pass the envelope sender address to sendmail by including the 5th parameter in the PHP mail() function, for example:

mail($to,$subject,$message,$headers, '-r [email protected]'); // Right way

In this case, the email recipient will receive an email with the following mail headers:

Return-Path: <[email protected]>
From: <[email protected]>

Since both of these headers contain addresses from domain.com, SPF will pass and also be aligned, which means that DMARC will also pass the SPF check.

You can use the jps utility that is included in the JDK to find the process id of a Java process. The output will show you the name of the executable JAR file or the name of the main class.

Then use the Windows task manager to terminate the process. If you want to do it on the command line, use

TASKKILL /PID %PID%

Rather than engage in a debating club, I would apply Defensive Programming. As a developer of an app that receives json data, I'd allow the trailing comma. When developing an app that writes json, I'd use one of the clever techniques of the other answers to only add commas between items. There are bigger problems to be solved...

My experience when using Dapper to connect to MySQL is that it does matter. I changed a non nullable bit(1) to a nullable tinyint(1) by using the following script:

ALTER TABLE TableName MODIFY Setting BOOLEAN null;

Then Dapper started throwing Exceptions. I tried to look at the difference before and after the script. And noticed the bit(1) had changed to tinyint(1).

I then ran:

ALTER TABLE TableName CHANGE COLUMN Setting Setting BIT(1) NULL DEFAULT NULL;

Which solved the problem.

NOTE: This answer is for SQL Server 2005. For SQL Server 2008 and later, there are much better methods as seen in the other answers.

You can use INSERT with SELECT UNION ALL:

INSERT INTO MyTable  (FirstCol, SecondCol)
    SELECT  'First' ,1
    UNION ALL
SELECT  'Second' ,2
    UNION ALL
SELECT  'Third' ,3
...

Only for small datasets though, which should be fine for your 4 records.

Read-Host is a simple option for getting string input from a user.

$name = Read-Host 'What is your username?'

To hide passwords you can use:

$pass = Read-Host 'What is your password?' -AsSecureString

To convert the password to plain text:

[Runtime.InteropServices.Marshal]::PtrToStringAuto(
    [Runtime.InteropServices.Marshal]::SecureStringToBSTR($pass))

As for the type returned by $host.UI.Prompt(), if you run the code at the link posted in @Christian's comment, you can find out the return type by piping it to Get-Member (for example, $results | gm). The result is a Dictionary where the key is the name of a FieldDescription object used in the prompt. To access the result for the first prompt in the linked example you would type: $results['String Field'].

To access information without invoking a method, leave the parentheses off:

PS> $Host.UI.Prompt

MemberType          : Method
OverloadDefinitions : {System.Collections.Generic.Dictionary[string,psobject] Pr
                    ompt(string caption, string message, System.Collections.Ob
                    jectModel.Collection[System.Management.Automation.Host.Fie
                    ldDescription] descriptions)}
TypeNameOfValue     : System.Management.Automation.PSMethod
Value               : System.Collections.Generic.Dictionary[string,psobject] Pro
                    mpt(string caption, string message, System.Collections.Obj
                    ectModel.Collection[System.Management.Automation.Host.Fiel
                    dDescription] descriptions)
Name                : Prompt
IsInstance          : True

$Host.UI.Prompt.OverloadDefinitions will give you the definition(s) of the method. Each definition displays as <Return Type> <Method Name>(<Parameters>).

The reason this is happening is because initializing an array does not initialize each element in that array. You need to first set houses[0] = new GameObject() and then it will work.

Check out the ColumnComparator. It is basically the same solution as proposed by Costi, but it also supports sorting on columns in a List and has a few more sort properties.

One thing to note:
I have had issues with websockets and corporate firewalls. (Using HTTPS helps but not always.)

See https://github.com/LearnBoost/socket.io/wiki/Socket.IO-and-firewall-software https://github.com/sockjs/sockjs-client/issues/94

I assume there aren't as many issues with Server-Sent Events. But I don't know.

That said, WebSockets are tons of fun. I have a little web game that uses websockets (via Socket.IO) (http://minibman.com)

For those not sure about which peak-finding algorithms to use in Python, here a rapid overview of the alternatives: https://github.com/MonsieurV/py-findpeaks

Wanting myself an equivalent to the MatLab findpeaks function, I've found that the detect_peaks function from Marcos Duarte is a good catch.

Pretty easy to use:

import numpy as np
from vector import vector, plot_peaks
from libs import detect_peaks
print('Detect peaks with minimum height and distance filters.')
indexes = detect_peaks.detect_peaks(vector, mph=7, mpd=2)
print('Peaks are: %s' % (indexes))

Which will give you:

You can only manually delete properties of objects. Thus:

var container = {};

container.instance = new class();

delete container.instance;

However, this won't work on any other pointers. Therefore:

var container = {};

container.instance = new class();

var pointer = container.instance;

delete pointer; // false ( ie attempt to delete failed )

Furthermore:

delete container.instance; // true ( ie attempt to delete succeeded, but... )

pointer; // class { destroy: function(){} }

So in practice, deletion is only useful for removing object properties themselves, and is not a reliable method for removing the code they point to from memory.

A manually specified destroy method could unbind any event listeners. Something like:

function class(){
  this.properties = { /**/ }

  function handler(){ /**/ }

  something.addEventListener( 'event', handler, false );

  this.destroy = function(){
    something.removeEventListener( 'event', handler );
  }
}

As simple as:

your_map.begin()->first // key
your_map.begin()->second // value

One can use the form.elements to get all elements in a form. If an element has id it can be found with .namedItem("id"). Example:

var myForm = document.getElementById("form1");
var text = myForm.elements.namedItem("searchTxt").value;
var url = "http://www.myurl.com/search/" + text;

header("Cache-Control: no-cache, must-revalidate");
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Content-Type: application/xml; charset=utf-8");

The token has to be placed in an Authorization header according to the following format:

Authorization: Bearer [Token_Value]

Code below:

import urllib2
import json

def get_auth_token():
    """
    get an auth token
    """
    req=urllib2.Request("https://xforce-api.mybluemix.net/auth/anonymousToken")
    response=urllib2.urlopen(req)
    html=response.read()
    json_obj=json.loads(html)
    token_string=json_obj["token"].encode("ascii","ignore")
    return token_string

def get_response_json_object(url, auth_token):
    """
    returns json object with info
    """
    auth_token=get_auth_token()
    req=urllib2.Request(url, None, {"Authorization": "Bearer %s" %auth_token})
    response=urllib2.urlopen(req)
    html=response.read()
    json_obj=json.loads(html)
    return json_obj

If you don't want to do it all by yourself, you can use the random.randrange function.

For example import random; print random.randrange(10, 25, 5) prints a number that is between 10 and 25 (10 included, 25 excluded) and is a multiple of 5. So it would print 10, 15, or 20.

If you guys are generating your stylesheets with LESS/SASS and are importing Bootstrap there, I've found that overriding the @navbar-height variable lets your set the height of the navbar, which is originally defined in the variables.less file.

This can actually be done with only CSS, but the content inside the div must be absolutely positioned. The key is to use padding as a percentage and the box-sizing: border-box CSS attribute:

div {_x000D_
  border: 1px solid red;_x000D_
  width: 40%;_x000D_
  padding: 40%;_x000D_
  box-sizing: border-box;_x000D_
  position: relative;_x000D_
}_x000D_
p {_x000D_
  position: absolute;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
}

<div>_x000D_
  <p>Some unnecessary content.</p>_x000D_
</div>

Adjust percentages to your liking. Here is a JSFiddle

var $table = $('#myTable2');
$table.bootstrapTable('destroy');

Worked for me

explode is an alternative. However, if you meant to split through a regular expression, the alternative is preg_split instead.

Exactly what it sounds like, assuming you're used to the abbreviated way in which C and UNIX assigns words, it duplicates strings :-)

Keeping in mind it's actually not part of the ISO C standard itself^(a) (it's a POSIX thing), it's effectively doing the same as the following code:

char *strdup(const char *src) {
    char *dst = malloc(strlen (src) + 1);  // Space for length plus nul
    if (dst == NULL) return NULL;          // No memory
    strcpy(dst, src);                      // Copy the characters
    return dst;                            // Return the new string
}

In other words:

1. It tries to allocate enough memory to hold the old string (plus a '\0' character to mark the end of the string).

2. If the allocation failed, it sets errno to ENOMEM and returns NULL immediately. Setting of errno to ENOMEM is something malloc does in POSIX so we don't need to explicitly do it in our strdup. If you're not POSIX compliant, ISO C doesn't actually mandate the existence of ENOMEM so I haven't included that here^(b).

3. Otherwise the allocation worked so we copy the old string to the new string^(c) and return the new address (which the caller is responsible for freeing at some point).

Keep in mind that's the conceptual definition. Any library writer worth their salary may have provided heavily optimised code targeting the particular processor being used.

^(a) However, functions starting with str and a lower case letter are reserved by the standard for future directions. From C11 7.1.3 Reserved identifiers:

Each header declares or defines all identifiers listed in its associated sub-clause, and *optionally declares or defines identifiers listed in its associated future library directions sub-clause.**

The future directions for string.h can be found in C11 7.31.13 String handling <string.h>:

Function names that begin with str, mem, or wcs and a lowercase letter may be added to the declarations in the <string.h> header.

So you should probably call it something else if you want to be safe.

^(b) The change would basically be replacing if (d == NULL) return NULL; with:

if (d == NULL) {
    errno = ENOMEM;
    return NULL;
}

^(c) Note that I use strcpy for that since that clearly shows the intent. In some implementations, it may be faster (since you already know the length) to use memcpy, as they may allow for transferring the data in larger chunks, or in parallel. Or it may not :-) Optimisation mantra #1: "measure, don't guess".

In any case, should you decide to go that route, you would do something like:

char *strdup(const char *src) {
    size_t len = strlen(src) + 1;       // String plus '\0'
    char *dst = malloc(len);            // Allocate space
    if (dst == NULL) return NULL;       // No memory
    memcpy (dst, src, len);             // Copy the block
    return dst;                         // Return the new string
}

You could create a new array containing that array, so:

<?php
$array = array();
$array['name'] = $oldArray;
?>

If you only want to sort only on the 5th field then use -k5,5.

Also, use the -t command line switch to specify the delimiter to tab. Try this:

sort  -k5,5 -r -n -t \t filename

or if the above doesn't work (with the tab) this:

sort  -k5,5 -r -n -t $'\t' filename

The man page for sort states:

-t, --field-separator=SEP use SEP instead of non-blank to blank transition

Finally, this SO question Unix Sort with Tab Delimiter might be helpful.

I was using a dialog `onError of a Video Player, and instead of going crazy (I've tested all of these solutions)

I've opted for DialogFragment http://developer.android.com/reference/android/app/DialogFragment.html.

You can return the builder creation in an inner DialogFragment class, just override onCreateDialog

This worked for me and seems simple...

$(function() {

});

Make sure your javascript is being executed after your element(s) have loaded, perhaps try putting the js file call just before the tag or use the defer attribute in your script, like so: <script src="app.js" defer></script> this makes sure that your script will be executed after the dom has loaded.

You can use pickle

import pickle
dict = {'one': 1, 'two': 2}
file = open('dump.txt', 'wb')
pickle.dump(dict, file)
file.close()

and to read it again

file = open('dump.txt', 'rb')
dict = pickle.load(file)

EDIT: Guess I misread your question, sorry ... but pickle might help all the same. :)

Finally it works for me.

Alternatively to SQL, you can do this in Microsoft SQL Server Management Studio. Here are a few quick ways using the GUI:

First Way

Slow double-click on the column. The column name will become an editable text box.

Second Way

Right click on column and choose Rename from the context menu.

For example:

Third Way

This way is preferable for when you need to rename multiple columns in one go.

1. Right-click on the table that contains the column that needs renaming.
2. Click Design.
3. In the table design panel, click and edit the textbox of the column name you want to alter.

For example:

_{NOTE: I know OP specifically asked for SQL solution, thought this might help others :)}

public Point2D(Point2D point) : this(point.X, point.Y) { }

I agree that using jQuery is the best option. You should also avoid using body's onload function and use jQuery's ready function instead. As for the event listeners, they should be functions that take one argument:

document.getElementById("foo").onclick = function (event){alert('foo');};

or in jQuery:

$('#foo').click(function(event) { alert('foo'); }

If you're running SQL Server 2005 or 2008, you could use the DMV's to find this...

I found a solution to this. It's bloody witchcraft, but it works.

When you install the client, open Control Panel > Network Connections.

You'll see a disabled network connection that was added by the TAP installer (Local Area Connection 3 or some such).

Right Click it, click Enable.

The device will not reset itself to enabled, but that's ok; try connecting w/ the client again. It'll work.

If anyone using hadoop1.2.1 version and not able to run namenode, go to core-site.xml, and change dfs.default.name to fs.default.name.

And then format the namenode using $hadoop namenode -format.

um responsive is simple

• first off create a class named cell give it the property of display:table-cell
• then @ max-width:700px do {display:block; width:100%; clear:both}

and that's it no absolute divs ever; divs needs to be 100% then max-width: - desired width - for inner framming. A true responsive sites has less than 9 lines of css anything passed that you are in a world of shit and over complicated things.

PS : reset.css style sheets are what makes css blinds there was a logical reason why they gave default styles in the first place.

I made a function version of Oscar's answer, this one also copies the environment and changes to the appropriate directory

function new_window {
    TMP_FILE=$(mktemp "/tmp/command.XXXXXX")
    echo "#!/usr/bin/env bash" > $TMP_FILE

    # Copy over environment (including functions), but filter out readonly stuff
    set | grep -v "\(BASH_VERSINFO\|EUID\|PPID\|SHELLOPTS\|UID\)" >> $TMP_FILE

    # Copy over exported envrionment
    export -p >> $TMP_FILE

    # Change to directory
    echo "cd $(pwd)" >> $TMP_FILE

    # Copy over target command line
    echo "$@" >> $TMP_FILE

    chmod +x "$TMP_FILE"
    open -b com.apple.terminal "$TMP_FILE"

    sleep .1 # Wait for terminal to start
    rm "$TMP_FILE"
}

You can use it like this:

new_window my command here

or

new_window ssh example.com

Needed to do a reverse on $.each so i used Vinay idea:

//jQuery.each(collection, callback) =>
$.each($(collection).get().reverse(), callback func() {});

worked nicely, thanks

Use substring and concatenate:

if(str.length() > 50)
    strOut = str.substring(0,7) + "...";

You can use the following regular expression which will match integers (e.g., 123), floating-point numbers (12.3), and numbers with exponents (1.2e3):

^-?\d*\.?\d+([eE]-?\d+)?$

If you want to accept + signs as well as - signs (as Oracle does with TO_NUMBER()), you can change each occurrence of - above to [+-]. So you might rewrite your block of code above as follows:

IF (option_id = 0021) THEN 
    IF NOT REGEXP_LIKE(value, '^[+-]?\d*\.?\d+([eE][+-]?\d+)?$') OR TO_NUMBER(value) < 10000 OR TO_NUMBER(value) > 7200000 THEN
        ip_msg(6214,option_name);
        RETURN;
    END IF;
END IF;

I am not altogether certain that would handle all values so you may want to add an EXCEPTION block or write a custom to_number() function as @JustinCave suggests.

Weird! You are saying that you want to generate a recursion of 1<<15 depth???!!!!

I'd suggest DON'T try it. The size of the stack will be 2^15 * sizeof(stack-frame). I don't know what stack-frame size is, but 2^15 is 32.768. Pretty much... Well, if it stops at 1024 (2^10) you'll have to make it 2^5 times bigger, it is, 32 times bigger than with your actual setting.
