May or may not be accurate, but according to this site: http://www.htmlite.com/mysql003.php.

BLOB A string with a maximum length of 65535 characters.

The MySQL manual says:

The maximum size of a BLOB or TEXT object is determined by its type, but the largest value you actually can transmit between the client and server is determined by the amount of available memory and the size of the communications buffers

I think the first site gets their answers from interpreting the MySQL manual, per http://dev.mysql.com/doc/refman/5.0/en/storage-requirements.html

michael's suggestions works like a charm for me :) If you replace $http.post with $http.get, remember that the .get method accepts 2 parameters instead of 3... this is where is wasted my time... ;)

controller:

$http.get('/getdoc/' + $stateParams.id,     
{responseType:'arraybuffer'})
  .success(function (response) {
     var file = new Blob([(response)], {type: 'application/pdf'});
     var fileURL = URL.createObjectURL(file);
     $scope.content = $sce.trustAsResourceUrl(fileURL);
});

view:

<object ng-show="content" data="{{content}}" type="application/pdf" style="width: 100%; height: 400px;"></object>

byte[] byteArray = rs.getBytes("columnname");  

Bitmap bm = BitmapFactory.decodeByteArray(byteArray, 0 ,byteArray.length);

Here's how you can do it in C#:

class Program
{
    static void Main(string[] args)
    {
        if (File.Exists("test.db3"))
        {
            File.Delete("test.db3");
        }
        using (var connection = new SQLiteConnection("Data Source=test.db3;Version=3"))
        using (var command = new SQLiteCommand("CREATE TABLE PHOTOS(ID INTEGER PRIMARY KEY AUTOINCREMENT, PHOTO BLOB)", connection))
        {
            connection.Open();
            command.ExecuteNonQuery();

            byte[] photo = new byte[] { 1, 2, 3, 4, 5 };

            command.CommandText = "INSERT INTO PHOTOS (PHOTO) VALUES (@photo)";
            command.Parameters.Add("@photo", DbType.Binary, 20).Value = photo;
            command.ExecuteNonQuery();

            command.CommandText = "SELECT PHOTO FROM PHOTOS WHERE ID = 1";
            using (var reader = command.ExecuteReader())
            {
                while (reader.Read())
                {
                    byte[] buffer = GetBytes(reader);
                }
            }

        }
    }

    static byte[] GetBytes(SQLiteDataReader reader)
    {
        const int CHUNK_SIZE = 2 * 1024;
        byte[] buffer = new byte[CHUNK_SIZE];
        long bytesRead;
        long fieldOffset = 0;
        using (MemoryStream stream = new MemoryStream())
        {
            while ((bytesRead = reader.GetBytes(0, fieldOffset, buffer, 0, buffer.Length)) > 0)
            {
                stream.Write(buffer, 0, (int)bytesRead);
                fieldOffset += bytesRead;
            }
            return stream.ToArray();
        }
    }
}

This is an async method which first checks for the availability of arrayBuffer method. This function is backward compatible and future proof.

async function blobToArrayBuffer(blob) {
    if ('arrayBuffer' in blob) return await blob.arrayBuffer();
    
    return new Promise((resolve, reject) => {
        const reader = new FileReader();
        reader.onload = () => resolve(reader.result);
        reader.onerror = () => reject;
        reader.readAsArrayBuffer(blob);
    });
}

1. insert into mytable(id, myblob) values (1,EMPTY_BLOB);
2. SELECT * FROM mytable mt where mt.id=1 for update
3. Click on the Lock icon to unlock for editing
4. Click on the ... next to the BLOB to edit
5. Select the appropriate tab and click open on the top left.
6. Click OK and commit the changes.

length and dbms_lob.getlength return the number of characters when applied to a CLOB (Character LOB). When applied to a BLOB (Binary LOB), dbms_lob.getlength will return the number of bytes, which may differ from the number of characters in a multi-byte character set.

As the documentation doesn't specify what happens when you apply length on a BLOB, I would advise against using it in that case. If you want the number of bytes in a BLOB, use dbms_lob.getlength.

You can simply right-click and save the blob as mp4.

When I was playing around with browser based video/audio recording the output blob was available to download directly.

The problem was that I had hexadecimal data that needed to be converted to binary before being base64encoded.

in PHP:

base64_encode(pack("H*", $subvalue))

You can use below SQL to read the BLOB Fields from table.

SELECT DBMS_LOB.SUBSTR(BLOB_FIELD_NAME) FROM TABLE_NAME;

The easiest way is this.

byte[] bytes = rs.getBytes("my_field");

another way to create a data url from blob url may be using canvas.

var canvas = document.createElement("canvas")
var context = canvas.getContext("2d")
context.drawImage(img, 0, 0) // i assume that img.src is your blob url
var dataurl = canvas.toDataURL("your prefer type", your prefer quality)

as what i saw in mdn, canvas.toDataURL is supported well by browsers. (except ie<9, always ie<9)

To convert Blob to String in Java:

byte[] bytes = baos.toByteArray();//Convert into Byte array
String blobString = new String(bytes);//Convert Byte Array into String

They can be considered as equivalent. The limits in size are the same:

• Maximum length of CLOB (in bytes or OCTETS)) 2 147 483 647
• Maximum length of BLOB (in bytes) 2 147 483 647

There is also the DBCLOBs, for double byte characters.

It took me a while to implement the other responses, as I'm using Angular 8 (tested up to 10). I ended up with the following code (heavily inspired by Hasan).

Note that for the name to be set, the header Access-Control-Expose-Headers MUST include Content-Disposition. To set this in django RF:

http_response = HttpResponse(package, content_type='application/javascript')
http_response['Content-Disposition'] = 'attachment; filename="{}"'.format(filename)
http_response['Access-Control-Expose-Headers'] = "Content-Disposition"

In angular:

  // component.ts
  // getFileName not necessary, you can just set this as a string if you wish
  getFileName(response: HttpResponse<Blob>) {
    let filename: string;
    try {
      const contentDisposition: string = response.headers.get('content-disposition');
      const r = /(?:filename=")(.+)(?:")/
      filename = r.exec(contentDisposition)[1];
    }
    catch (e) {
      filename = 'myfile.txt'
    }
    return filename
  }

  
  downloadFile() {
    this._fileService.downloadFile(this.file.uuid)
      .subscribe(
        (response: HttpResponse<Blob>) => {
          let filename: string = this.getFileName(response)
          let binaryData = [];
          binaryData.push(response.body);
          let downloadLink = document.createElement('a');
          downloadLink.href = window.URL.createObjectURL(new Blob(binaryData, { type: 'blob' }));
          downloadLink.setAttribute('download', filename);
          document.body.appendChild(downloadLink);
          downloadLink.click();
        }
      )
  }

  // service.ts
  downloadFile(uuid: string) {
    return this._http.get<Blob>(`${environment.apiUrl}/api/v1/file/${uuid}/package/`, { observe: 'response', responseType: 'blob' as 'json' })
  }

BLOB :

BLOB (Binary Large Object) is a large object data type in the database system. BLOB could store a large chunk of data, document types and even media files like audio or video files. BLOB fields allocate space only whenever the content in the field is utilized. BLOB allocates spaces in Giga Bytes.

USAGE OF BLOB :

You can write a binary large object (BLOB) to a database as either binary or character data, depending on the type of field at your data source. To write a BLOB value to your database, issue the appropriate INSERT or UPDATE statement and pass the BLOB value as an input parameter. If your BLOB is stored as text, such as a SQL Server text field, you can pass the BLOB as a string parameter. If the BLOB is stored in binary format, such as a SQL Server image field, you can pass an array of type byte as a binary parameter.

A useful link : Storing documents as BLOB in Database - Any disadvantages ?

i also recommend thinking this thru and then choosing to store images in your file system rather than the DB .. see here: Storing Images in DB - Yea or Nay?

I have three answers to this question:

1. It is against user experience UX best practice to use BLOB and CLOB data types in string and retrieving binary data from an SQL database thus it is advised that you use the technique that involves storing the URL for the image( or any Binary file in the database). This URL will help the user application to retrieve and use this binary file.

2. Second the BLOB and CLOB data types are only available to a number of SQL versions thus functions such as LOAD_FILE or the datatypes themselves could miss in some versions.

3. Third DON'T USE BLOB OR CLOB. Store the URL; let the user application access the binary file from a folder in the project directory.

What client do you use? .Net, Java, Ruby, SQLPLUS, SQL DEVELOPER? Where did you write that simple select statement?

And why do you want to read the content of the blob, a blob contains binary data so that data is unreadable. You should use a clob instead of a blob if you want to store text instead of binary content.

I suggest that you download SQL DEVELOPER: http://www.oracle.com/technetwork/developer-tools/sql-developer/overview/index.html . With SQL DEVELOPER you can see the content.

The word on the street is that unless you are a database vendor trying to prove that your database can do it (like, let's say Microsoft boasting about Terraserver storing a bajillion images in SQL Server) it's not a very good idea. When the alternative - storing images on file servers and paths in the database is so much easier, why bother? Blob fields are kind of like the off-road capabilities of SUVs - most people don't use them, those who do usually get in trouble, and then there are those who do, but only for the fun of it.

To do this task download.js library can be used. Here is an example from library docs:

download("data:image/gif;base64,R0lGODlhRgAVAIcAAOfn5+/v7/f39////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////yH5BAAAAP8ALAAAAABGABUAAAj/AAEIHAgggMGDCAkSRMgwgEKBDRM+LBjRoEKDAjJq1GhxIMaNGzt6DAAypMORJTmeLKhxgMuXKiGSzPgSZsaVMwXUdBmTYsudKjHuBCoAIc2hMBnqRMqz6MGjTJ0KZcrz5EyqA276xJrVKlSkWqdGLQpxKVWyW8+iJcl1LVu1XttafTs2Lla3ZqNavAo37dm9X4eGFQtWKt+6T+8aDkxUqWKjeQUvfvw0MtHJcCtTJiwZsmLMiD9uplvY82jLNW9qzsy58WrWpDu/Lp0YNmPXrVMvRm3T6GneSX3bBt5VeOjDemfLFv1XOW7kncvKdZi7t/S7e2M3LkscLcvH3LF7HwSuVeZtjuPPe2d+GefPrD1RpnS6MGdJkebn4/+oMSAAOw==", "dlDataUrlBin.gif", "image/gif");

Found this...

bcp "SELECT top 1 BlobText FROM TableName" queryout "C:\DesinationFolder\FileName.txt" -T -c'

If you need to know about different options of bcp flags...

Here goes what O'reilly Enterprise JavaBeans, 3.0 says

JDBC has special types for these very large objects. The java.sql.Blob type represents binary data, and java.sql.Clob represents character data.

Here goes PostgreSQLDialect source code

public PostgreSQLDialect() {
    super();
    ...
    registerColumnType(Types.VARBINARY, "bytea");
    /**
      * Notice it maps java.sql.Types.BLOB as oid
      */
    registerColumnType(Types.BLOB, "oid");
}

So what you can do

Override PostgreSQLDialect as follows

public class CustomPostgreSQLDialect extends PostgreSQLDialect {

    public CustomPostgreSQLDialect() {
        super();

        registerColumnType(Types.BLOB, "bytea");
    }
}

Now just define your custom dialect

<property name="hibernate.dialect" value="br.com.ar.dialect.CustomPostgreSQLDialect"/>

And use your portable JPA @Lob annotation

@Lob
public byte[] getValueBuffer() {

UPDATE

Here has been extracted here

I have an application running in hibernate 3.3.2 and the applications works fine, with all blob fields using oid (byte[] in java)

...

Migrating to hibernate 3.5 all blob fields not work anymore, and the server log shows: ERROR org.hibernate.util.JDBCExceptionReporter - ERROR: column is of type oid but expression is of type bytea

which can be explained here

This generaly is not bug in PG JDBC, but change of default implementation of Hibernate in 3.5 version. In my situation setting compatible property on connection did not helped.

...

Much more this what I saw in 3.5 - beta 2, and i do not know if this was fixed is Hibernate - without @Type annotation - will auto-create column of type oid, but will try to read this as bytea

Interesting is because when he maps Types.BOLB as bytea (See CustomPostgreSQLDialect) He get

Could not execute JDBC batch update

when inserting or updating

You cannot access a local directory from pl/sql. If you use bfile, you will setup a directory (create directory) on the server where Oracle is running where you will need to put your images.

If you want to insert a handful of images from your local machine, you'll need a client side app to do this. You can write your own, but I typically use Toad for this. In schema browser, click onto the table. Click the data tab, and hit + sign to add a row. Double click the BLOB column, and a wizard opens. The far left icon will load an image into the blob:

SQL Developer has a similar feature. See the "Load" link below:

If you need to pull images over the wire, you can do it using pl/sql, but its not straight forward. First, you'll need to setup ACL list access (for security reasons) to allow a user to pull over the wire. See this article for more on ACL setup.

Assuming ACL is complete, you'd pull the image like this:

declare
    l_url varchar2(4000) := 'http://www.oracleimg.com/us/assets/12_c_navbnr.jpg';
    l_http_request   UTL_HTTP.req;
    l_http_response  UTL_HTTP.resp;
    l_raw RAW(2000);
    l_blob BLOB;
begin
   -- Important: setup ACL access list first!

    DBMS_LOB.createtemporary(l_blob, FALSE);

    l_http_request  := UTL_HTTP.begin_request(l_url);
    l_http_response := UTL_HTTP.get_response(l_http_request);

  -- Copy the response into the BLOB.
  BEGIN
    LOOP
      UTL_HTTP.read_raw(l_http_response, l_raw, 2000);
      DBMS_LOB.writeappend (l_blob, UTL_RAW.length(l_raw), l_raw);
    END LOOP;
  EXCEPTION
    WHEN UTL_HTTP.end_of_body THEN
      UTL_HTTP.end_response(l_http_response);
  END;

  insert into my_pics (pic_id, pic) values (102, l_blob);
  commit;

  DBMS_LOB.freetemporary(l_blob); 
end;

Hope that helps.

For me what worked by combining all the posts I have read is:

1.Enable OLE automation - if not enabled

sp_configure 'show advanced options', 1;  
GO  
RECONFIGURE;  
GO  
sp_configure 'Ole Automation Procedures', 1;  
GO  
RECONFIGURE;  
GO

2.Create a folder where the generated files will be stored:

C:\GREGTESTING

3.Create DocTable that will be used for file generation and store there the blobs in Doc_Content

CREATE TABLE [dbo].[Document](
    [Doc_Num] [numeric](18, 0) IDENTITY(1,1) NOT NULL,
    [Extension] [varchar](50) NULL,
    [FileName] [varchar](200) NULL,
    [Doc_Content] [varbinary](max) NULL   
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY] 

INSERT [dbo].[Document] ([Extension] ,[FileName] , [Doc_Content] )
    SELECT 'pdf', 'SHTP Notional hire - January 2019.pdf', 0x....(varbinary blob)

Important note!

Don't forget to add in Doc_Content column the varbinary of file you want to generate!

4.Run the below script

DECLARE @outPutPath varchar(50) = 'C:\GREGTESTING'
, @i bigint
, @init int
, @data varbinary(max) 
, @fPath varchar(max)  
, @folderPath  varchar(max)

--Get Data into temp Table variable so that we can iterate over it 
DECLARE @Doctable TABLE (id int identity(1,1), [Doc_Num]  varchar(100) , [FileName]  varchar(100), [Doc_Content] varBinary(max) )



INSERT INTO @Doctable([Doc_Num] , [FileName],[Doc_Content])
Select [Doc_Num] , [FileName],[Doc_Content] FROM  [dbo].[Document]



SELECT @i = COUNT(1) FROM @Doctable   

WHILE @i >= 1   

BEGIN    

SELECT 
    @data = [Doc_Content],
    @fPath = @outPutPath + '\' + [Doc_Num] +'_' +[FileName],
    @folderPath = @outPutPath + '\'+ [Doc_Num]
FROM @Doctable WHERE id = @i

EXEC sp_OACreate 'ADODB.Stream', @init OUTPUT; -- An instace created
EXEC sp_OASetProperty @init, 'Type', 1;  
EXEC sp_OAMethod @init, 'Open'; -- Calling a method
EXEC sp_OAMethod @init, 'Write', NULL, @data; -- Calling a method
EXEC sp_OAMethod @init, 'SaveToFile', NULL, @fPath, 2; -- Calling a method
EXEC sp_OAMethod @init, 'Close'; -- Calling a method
EXEC sp_OADestroy @init; -- Closed the resources
print 'Document Generated at - '+  @fPath   

--Reset the variables for next use
SELECT @data = NULL  
, @init = NULL
, @fPath = NULL  
, @folderPath = NULL
SET @i -= 1
END   

5.The results is shown below:

window.location.assign did not work for me. it downloads fine but downloads without an extension for a CSV file on Windows platform. The following worked for me.

    var blob = new Blob([csvString], { type: 'text/csv' });
    //window.location.assign(window.URL.createObjectURL(blob));
    var link = window.document.createElement('a');
    link.href = window.URL.createObjectURL(blob);
    // Construct filename dynamically and set to link.download
    link.download = link.href.split('/').pop() + '.' + extension; 
    document.body.appendChild(link);
    link.click();
    document.body.removeChild(link);

However you can simply read a file from disk on SQL server machine:

select * from openrowset (bulk 'c:\path\filename.ext',single_blob) a

to see it in management application in hex form (Management Studio).

So, you can, for example, backup database to file (locally on server) and then download it to other place by the statement above.

Typescript

public blobToFile = (theBlob: Blob, fileName:string): File => {

Javascript

function blobToFile(theBlob, fileName){       
    return new File([theBlob], fileName, { lastModified: new Date().getTime(), type: theBlob.type })
}

Output

A BLOB is a binary string to hold a variable amount of data. For the most part BLOB's are used to hold the actual image binary instead of the path and file info. Text is for large amounts of string characters. Normally a blog or news article would constitute to a TEXT field

L in this case is used stating the storage requirement. (Length|Size + 3) as long as it is less than 224.

The simple answer is that you can't reliably log out of http-authentication.

The long answer:
Http-auth (like the rest of the HTTP spec) is meant to be stateless. So being "logged in" or "logged out" isn't really a concept that makes sense. The better way to see it is to ask, for each HTTP request (and remember a page load is usually multiple requests), "are you allowed to do what you're requesting?". The server sees each request as new and unrelated to any previous requests.

Browsers have chosen to remember the credentials you tell them on the first 401, and re-send them without the user's explicit permission on subsequent requests. This is an attempt at giving the user the "logged in/logged out" model they expect, but it's purely a kludge. It's the browser that's simulating this persistence of state. The web server is completely unaware of it.

So "logging out", in the context of http-auth is purely a simulation provided by the browser, and so outside the authority of the server.

Yes, there are kludges. But they break RESTful-ness (if that's of value to you) and they are unreliable.

If you absolutely require a logged-in/logged-out model for your site authentication, the best bet is a tracking cookie, with the persistence of state stored on the server in some manner (mysql, sqlite, flatfile, etc). This will require all requests to be evaluated, for instance, with PHP.

Use

RefreshForm.submit(); 

instead of

document.location.reload(true); 

I know this is extremely late, but for anyone still wondering here's an easy solution.

You could just make an array for the styles :

this.state ={
   color: "#fff"
}

style={[
  styles.jewelstyle, {
  backgroundColor: this.state.BGcolor
}

The second will override any original background color as stated in the stylesheet. Then have a function that changes the color:

generateNewColor(){
  var randomColor = '#'+Math.floor(Math.random()*16777215).toString(16);
  this.setState({BGcolor: randomColor})
}

This will generate a random hex color. Then just call that function whenever and bam, new background color.

For Google Chrome (Tested on ver. 62)

I was trying to keep a socket connection alive from the google chrome's fetch API to a remote express server and found the request headers have to match Node.JS's native <net.socket> connection settings.

I set the headers object on my client-side script with the following options:

/* ----- */
head = new headers();
head.append("Connnection", "keep-alive")
head.append("Keep-Alive", `timeout=${1*60*5}`) //in seconds, not milliseconds
/* apply more definitions to the header */
fetch(url, {
    method: 'OPTIONS',
    credentials: "include",
    body: JSON.stringify(data),
    cors: 'cors',
    headers: head, //could be object literal too
    cache: 'default'
 })
 .then(response=>{
    ....
  }).catch(err=>{...});

And on my express server I setup my router as follows:

 router.head('absolute or regex', (request, response, next)=>{
  req.setTimeout(1000*60*5, ()=>{
     console.info("socket timed out");
   });
  console.info("Proceeding down the middleware chain link...\n\n");
  next();
 });

 /*Keep the socket alive by enabling it on the server, with an optional 
  delay on the last packet sent 
 */
server.on('connection', (socket)=>socket.setKeepAlive(true, 10))

WARNING

Please use common sense and make sure the users you're keeping the socket connection open to is validated and serialized. It works for Firefox as well, but it's really vulnerable if you keep the TCP connection open for longer than 5 minutes.

I'm not sure how some of the lesser known browsers operate, but I'll append to this answer with the Microsoft browser details as well.

Since assertThat which was the old answer is now deprecated, I am posting the correct solution:

assertTrue(objectUnderTest instanceof TargetObject);

In your component.ts

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

@Component({
  ...
})
export class AppComponent {
  ...
  goToSpecificUrl(url): void {
    window.location.href=url;
  }

  gotoGoogle() : void {
    window.location.href='https://www.google.com';
  }
}

In your component.html

<button type="button" (click)="goToSpecificUrl('http://stackoverflow.com/')">Open URL</button>
<button type="button" (click)="gotoGoogle()">Open Google</button>

<li *ngFor="item of itemList" (click)="goToSpecificUrl(item.link)"> // (click) don't enable pointer when we hover so we should enable it by using css like: **cursor: pointer;**

How about this one-liner (in bash):

mkdir --parents ./some/path/; mv yourfile.txt $_

Breaking that down:

mkdir --parents ./some/path

creates the directory (including all intermediate directories), after which:

mv yourfile.txt $_

moves the file to that directory ($_ expands to the last argument passed to the previous shell command, ie: the newly created directory).

I am not sure how far this will work in other shells, but it might give you some ideas about what to look for.

Here is an example using this technique:

$ > ls
$ > touch yourfile.txt

First you can use a Paginator. This is as simple as:

$allUsers = User::paginate(15);

$someUsers = User::where('votes', '>', 100)->paginate(15);

The variables will contain an instance of Paginator class. all of your data will be stored under data key.

Or you can do something like:

Old versions Laravel.

Model::all()->take(10)->get();

Newer version Laravel.

Model::all()->take(10);

• pagination docs
• passing data to views
• Eloquent basic usage
• A cheat sheet

For one, you can't modify string literals. It's undefined behavior.

To fix that you can make str a local array:

char str[] = "First string";

Now, you will have a second problem, is that str isn't large enough to hold str2. So you will need to increase the length of it. Otherwise, you will overrun str - which is also undefined behavior.

To get around this second problem, you either need to make str at least as long as str2. Or allocate it dynamically:

char *str2 = "Second string";
char *str = malloc(strlen(str2) + 1);  //  Allocate memory
//  Maybe check for NULL.

strcpy(str, str2);

//  Always remember to free it.
free(str);

There are other more elegant ways to do this involving VLAs (in C99) and stack allocation, but I won't go into those as their use is somewhat questionable.

As @SangeethSaravanaraj pointed out in the comments, everyone missed the #import. It should be #include:

#include <stdio.h>
#include <string.h>

I had the same problem with a custom class, which was defined in a namespace. I tried to use the class without the namespace, causing the compiler error "identifier "MyClass" is undefined". Adding

using namespace <MyNamespace>

or using the class like

MyNamespace::MyClass myClass;

solved the problem.

The Test-Connection command seems to be a useful alternative, and it can either provide either a Win32_PingStatus object, or a boolean value.

Use the CheckBoxList's GetItemChecked or GetItemCheckState method to find out whether an item is checked or not by its index.

It's really just a matter of taste. Adding the shebang means people can invoke the script directly if they want (assuming it's marked as executable); omitting it just means python has to be invoked manually.

The end result of running the program isn't affected either way; it's just options of the means.

On Xcode Version 8.1 (8B62) it can be done directly in Attributes Inspector. Select the textField and then choose the appropriate option from Clear Button drop down box, which is located in Attributes Inspector.

If you want to cleanup docker images and containers

CAUTION: this will flush everything

stop all containers

docker stop $(docker ps -a -q)

remove all containers

docker rm $(docker ps -a -q)

remove all images

docker rmi -f $(docker images -a -q)

At CentOS (actually I think all linux distros are similar) run

env|grep http_proxy

and

env|grep https_proxy

check what is the output of those commands (they should contain your proxy addresses).

If the outputs are empty or have incorrect values, modify them, for ex:

export http_proxy=http://10.1.1.1:8080
export https_proxy=http://10.1.1.1:8080

Now try to fetch and install some packages by using pip:

pip --proxy http://10.1.1.1:8080 install robotframework

and actually I have never met the case when it didn't work. For some systems you need to be a root (sudo is not enough).

If all you need is mousedown, you may be able to make do with the document.elementFromPoint method, by:

1. removing the top layer on mousedown,
2. passing the x and y coordinates from the event to the document.elementFromPoint method to get the element underneath, and then
3. restoring the top layer.

Motivation for creating the Java Persistence API

Many enterprise Java developers use lightweight persistent objects provided by open-source frameworks or Data Access Objects instead of entity beans: entity beans and enterprise beans had a reputation of being too heavyweight and complicated, and one could only use them in Java EE application servers. Many of the features of the third-party persistence frameworks were incorporated into the Java Persistence API, and as of 2006 projects like Hibernate (version 3.2) and Open-Source Version TopLink Essentials have become implementations of the Java Persistence API.

As told in the JCP page the Eclipse link is the Reference Implementation for JPA. Have look at this answer for bit more on this.

JPA itself has features that will make up for a standard ORM framework. Since JPA is a part of Java EE spec, you can use JPA alone in a project and it should work with any Java EE compatible Servers. Yes, these servers will have the implementations for the JPA spec.

Hibernate is the most popular ORM framework, once the JPA got introduced hibernate conforms to the JPA specifications. Apart from the basic set of specification that it should follow hibernate provides whole lot of additional stuff.

CSS layouts are generally much better for accessibility, provided the content comes in a natural order and makes sense without a stylesheet. And it's not just screen readers that struggle with table-based layouts: they also make it much harder for mobile browsers to render a page properly.

Also, with a div-based layout you can very easily do cool things with a print stylesheet such as excluding headers, footers and navigation from printed pages - I think it would be impossible, or at least much more difficult, to do that with a table-based layout.

If you're doubting that separation of content from layout is easier with divs than with tables, take a look at the div-based HTML at CSS Zen Garden, see how changing the stylesheets can drastically change the layout, and think about whether you could achieve the same variety of layouts if the HTML was table based... If you're doing a table-based layout, you're unlikely to be using CSS to control all the spacing and padding in the cells (if you were, you'd almost certainly find it easier to use floating divs etc. in the first place). Without using CSS to control all that, and because of the fact that tables specify the left-to-right and top-to bottom order of things in the HTML, tables tend to mean that your layout becomes very much fixed in the HTML.

Realistically I think it's very hard to completely change the layout of a div-and-CSS-based design without changing the divs a bit. However, with a div-and-CSS-based layout it's much easier to tweak things like the spacing between various blocks, and their relative sizes.

It is varchar and not var_char

CREATE DATABASE IF NOT EXISTS courses;

    addr VARCHAR(255) NOT NULL,
    phone INT NOT NULL
);

You should use a SQL tool to visualize possbile errors like MySQL Workbench.

In rare cases, it can be useful to change the line that is given by __LINE__ to something else. I've seen GNU configure does that for some tests to report appropriate line numbers after it inserted some voodoo between lines that do not appear in original source files. For example:

#line 100

Will make the following lines start with __LINE__ 100. You can optionally add a new file-name

#line 100 "file.c"

It's only rarely useful. But if it is needed, there are no alternatives I know of. Actually, instead of the line, a macro can be used too which must result in any of the above two forms. Using the boost preprocessor library, you can increment the current line by 50:

#line BOOST_PP_ADD(__LINE__, 50)

I thought it's useful to mention it since you asked about the usage of __LINE__ and __FILE__. One never gets enough surprises out of C++ :)

Edit: @Jonathan Leffler provides some more good use-cases in the comments:

Messing with #line is very useful for pre-processors that want to keep errors reported in the user's C code in line with the user's source file. Yacc, Lex, and (more at home to me) ESQL/C preprocessors do that.

It depends on how you want to use it. Using a Join is one way. Another way of doing it is let the thread notify the caller of the thread by using an event. For instance when you have your graphical user interface (GUI) thread that calls a process which runs for a while and needs to update the GUI when it finishes, you can use the event to do this. This website gives you an idea about how to work with events:

http://msdn.microsoft.com/en-us/library/aa645739%28VS.71%29.aspx

Remember that it will result in cross-threading operations and in case you want to update the GUI from another thread, you will have to use the Invoke method of the control which you want to update.

=IF(ISNA(INDEX(B:B,MATCH(C2,A:A,0))),"",INDEX(B:B,MATCH(C2,A:A,0)))

Will return the answer you want and also remove the #N/A result that would appear if you couldn't find a result due to it not appearing in your lookup list.

In addition to the perfect and valid answers given so far, there is also the ignore_row_on_dupkey_index hint you might want to use:

create table tq84_a (
  name varchar2 (20) primary key,
  age  number
);

insert /*+ ignore_row_on_dupkey_index(tq84_a(name)) */ into tq84_a values ('Johnny',   77);
insert /*+ ignore_row_on_dupkey_index(tq84_a(name)) */ into tq84_a values ('Pete'  ,   28);
insert /*+ ignore_row_on_dupkey_index(tq84_a(name)) */ into tq84_a values ('Sue'   ,   35);
insert /*+ ignore_row_on_dupkey_index(tq84_a(name)) */ into tq84_a values ('Johnny', null);

select * from tq84_a;

The hint is described on Tahiti.

urlretrieve is not work for me, and the official document said that They might become deprecated at some point in the future.

import shutil 
from urllib.request import URLopener
opener = URLopener()
url = 'ftp://ftp_domain/path/to/the/file'

    shutil.copyfileobj(remote_file, local_file)

Struggled to solve this one, checked the load order and if jQuery was included twice via bundling, but that didn't seem to be the cause.

Finally fixed it by making the following change:

(before):

$('#myModal').modal('hide');

(after):

window.$('#myModal').modal('hide');

Found the answer here: https://github.com/ColorlibHQ/AdminLTE/issues/685

1. $() means: "first evaluate this, and then evaluate the rest of the line".

   Ex :

   echo $(pwd)/myFile.txt
   

   will be interpreted as

   echo /my/path/myFile.txt
   

   On the other hand ${} expands a variable.

   Ex:

   MY_VAR=toto
   echo ${MY_VAR}/myFile.txt
   

   will be interpreted as

   echo toto/myFile.txt
   

2. Why can't I use it as bash$ while ((i=0;i<10;i++)); do echo $i; done

   I'm afraid the answer is just that the bash syntax for while just isn't the same as the syntax for for.

JUnit 4 does not have any out-of-the-box mechanism for a test case to get it’s own name (including during setup and teardown).

Create a div, which contains both divs (full and someid) and set the height of that div to the following:

height: 100vh;

The height of the containing divs (full and someid) should be set to "auto". That's all.

The error in question may also be caused by disabled JarScanner in tomcat/conf/context.xml.

Using the command line is an option, and would remove the need for an Eclipse Plugin. First, create a directory to hold the project.

mkdir myGitRepo
cd myGitRepo

Clone the desired repository in the directory you just created.

git clone https://github.com/JonasHelming/gitTutorial.git

Then open Eclipse and select the directory you created (myGitRepo) as the Eclipse Workspace.

Don't worry that the Project Explorer is empty, Eclipse can't recognize the source files yet.

Lastly, create a new Java project with the exact same name as the project you pulled. In this case, it was 'gitTutorial'.

File -> New -> Java Project

At this point, the project's sub directories should contain the files pulled from Github. Take a look at the following post in my blog for a more detailed explanation.

I've come across this thread when suffering the same error, after doing some research I can confirm, this is an error that happens when you try to decode a UTF-16 file with UTF-8.

With UTF-16 the first characther (2 bytes in UTF-16) is a Byte Order Mark (BOM), which is used as a decoding hint and doesn't appear as a character in the decoded string. This means the first byte will be either FE or FF and the second, the other.

Heavily edited after I found out the real answer

Hide the body initially, and then show it with jQuery after it has loaded.

body {
    display: none;
}

$(function () {
    $('body').show();
}); // end ready

Also, it would be best to have $('body').show(); as the last line in your last and main .js file.

As you might be aware of, Maven is a build automation tool provided by Apache which does more than dependency management. We can make it as a peer of Ant and Makefile which downloads all of the dependencies required.

On a mvn install, it frames a dependency tree based on the project configuration pom.xml on all the sub projects under the super pom.xml (the root POM) and downloads/compiles all the needed components in a directory called .m2 under the user's folder. These dependencies will have to be resolved for the project to be built without any errors, and mvn install is one utility that could download most of the dependencies.

Further, there are other utils within Maven like dependency:resolve which can be used separately in any specific cases. The build life cycle of the mvn is as below: LifeCycle Bindings

1. process-resources
2. compile
3. process-test-resources
4. test-compile
5. test
6. package
7. install
8. deploy

The test phase of this mvn can be ignored by using a flag -DskipTests=true.

I don't understand the need of having private setters which started with C# 2.

Use case example:

I have an instance of an application object 'UserInfo' that contains a property SessionTokenIDV1 that I don't wish to expose to consumers of my class.

I also need the ability to set that value from my class.

My solution was to encapsulate the property as shown and make the setter private so that I can set the value of the session token without allowing instantiating code to also set it (or even see it in my case)

public class UserInfo
{
   public String SessionTokenIDV1 { get; set; }

}


public class Example
{
  // Private vars
  private UserInfo _userInfo = new UserInfo();

  public string SessionValidV1
  {
    get { return ((_userInfo.SessionTokenIDV1 != null) && (_userInfo.SessionTokenIDV1.Length > 0)) ? "set" : "unset"; }
    private set { _userInfo.SessionTokenIDV1 = value; }
  }
}

Edit: Fixed Code Tag Edit: Example had errors which have been corrected

Assume file is already created in the predefined directory with name "table.txt"

• 1) change the ownership for file :

  sudo chown username:username table.txt
  

• 2) change the mode of the file

  sudo chmod 777 table.txt
  

Now, try it should work!

Hehe, curious. I think this is an "intentianal bug", so to speak.

The underlying reason is how the Integer class is written. Basically, parseInt is "optimized" for positive numbers. When it parses the string, it builds the result cumulatively, but negated. Then it flips the sign of the end-result.

Example:

66 = 0x42

parsed like:

4*(-1) = -4
-4 * 16 = -64 (hex 4 parsed)

-64 - 2 = -66 (hex 2 parsed)

return -66 * (-1) = 66

Now, let's look at your example FFFF8000

16*(-1) = -16 (first F parsed)
-16*16 = -256 

-256 - 16 = -272 (second F parsed)
-272 * 16 = -4352 

-4352 - 16 = -4368 (third F parsed)
-4352 * 16 = -69888

-69888 - 16 = -69904 (forth F parsed)
-69904 * 16 = -1118464 

-1118464 - 8 = -1118472 (8 parsed)
-1118464 * 16 = -17895552 

-17895552 - 0 = -17895552 (first 0 parsed)
Here it blows up since -17895552 < -Integer.MAX_VALUE / 16 (-134217728). 
Attempting to execute the next logical step in the chain (-17895552 * 16)
would cause an integer overflow error.

Edit (addition): in order for the parseInt() to work "consistently" for -Integer.MAX_VALUE <= n <= Integer.MAX_VALUE, they would have had to implement logic to "rotate" when reaching -Integer.MAX_VALUE in the cumulative result, starting over at the max-end of the integer range and continuing downwards from there. Why they did not do this, one would have to ask Josh Bloch or whoever implemented it in the first place. It might just be an optimization.

However,

Hex=Integer.toHexString(Integer.MAX_VALUE);
System.out.println(Hex);
System.out.println(Integer.parseInt(Hex.toUpperCase(), 16));

works just fine, for just this reason. In the sourcee for Integer you can find this comment.

// Accumulating negatively avoids surprises near MAX_VALUE

Try:

from p in db.Products
where !theBadCategories.Contains(p.Category)
select p;

If you want to determine the equation of the curve through n points then the following code will give you the coefficients of the polynomial of degree n-1 and save these coefficients to the coefficients[] array (starting from the constant term). The x coordinates do not have to be in order. This is an example of a Lagrange polynomial.

var xPoints=[2,4,3,6,7,10]; //example coordinates
var yPoints=[2,5,-2,0,2,8];
var coefficients=[];
for (var m=0; m<xPoints.length; m++) coefficients[m]=0;
    for (var m=0; m<xPoints.length; m++) {
        var newCoefficients=[];
        for (var nc=0; nc<xPoints.length; nc++) newCoefficients[nc]=0;
        if (m>0) {
            newCoefficients[0]=-xPoints[0]/(xPoints[m]-xPoints[0]);
            newCoefficients[1]=1/(xPoints[m]-xPoints[0]);
    } else {
        newCoefficients[0]=-xPoints[1]/(xPoints[m]-xPoints[1]);
        newCoefficients[1]=1/(xPoints[m]-xPoints[1]);
    }
    var startIndex=1; 
    if (m==0) startIndex=2; 
    for (var n=startIndex; n<xPoints.length; n++) {
        if (m==n) continue;
        for (var nc=xPoints.length-1; nc>=1; nc--) {
        newCoefficients[nc]=newCoefficients[nc]*(-xPoints[n]/(xPoints[m]-xPoints[n]))+newCoefficients[nc-1]/(xPoints[m]-xPoints[n]);
        }
        newCoefficients[0]=newCoefficients[0]*(-xPoints[n]/(xPoints[m]-xPoints[n]));
    }    
    for (var nc=0; nc<xPoints.length; nc++) coefficients[nc]+=yPoints[m]*newCoefficients[nc];
}

armhf stands for "arm hard float", and is the name given to a debian port for arm processors (armv7+) that have hardware floating point support.

On the beaglebone black, for example:

:~$ dpkg --print-architecture
armhf

Although other commands (such as uname -a or arch) will just show armv7l

:~$ cat /proc/cpuinfo 
processor       : 0
model name      : ARMv7 Processor rev 2 (v7l)
BogoMIPS        : 995.32
Features        : half thumb fastmult vfp edsp thumbee neon vfpv3 tls
...

The vfpv3 listed under Features is what refers to the floating point support.

Incidentally, armhf, if your processor supports it, basically supersedes Raspbian, which if I understand correctly was mainly a rebuild of armhf with work arounds to deal with the lack of floating point support on the original raspberry pi's. Nowdays, of course, there's a whole ecosystem build up around Raspbian, so they're probably not going to abandon it. However, this is partly why the beaglebone runs straight debian, and that's ok even if you're used to Raspbian, unless you want some of the special included non-free software such as Mathematica.

I checked the Node version in my local machine, which is v10.11.0.

Then when I checked my development machine, where the error occurred, it had Node version V.10.8.0.

Upgrading Node to v10.11.0 in my development machine fixed the issue.

Hope this helps.

        } else if (metrics.densityDpi <= DisplayMetrics.DENSITY_MEDIUM) {
            r = "mdpi";

Ensure you have xunit.runner.visualstudio package in your test project packages.config and also that was correctly restored.

I know this was not the case of the original question however it could save time for someone like me.

This will depend on the device you're using. If you're using a pdf device, you can do this:

pdf( "mygraph.pdf", width = 11, height = 8 )
plot( x, y )

You can then divide up the space in the pdf using the mfrow parameter like this:

par( mfrow = c(2,2) )

That makes a pdf with four panels available for plotting. Unfortunately, some of the devices take different units than others. For example, I think that X11 uses pixels, while I'm certain that pdf uses inches. If you'd just like to create several devices and plot different things to them, you can use dev.new(), dev.list(), and dev.next().

Other devices that might be useful include:

• X11
• postscript
• BMP, JPEG, PNG and TIFF
• quartz (OSX only)

There's a list of all of the devices here.

On elasticsearch 5.6, I have to use command below to filter out empty string:

    GET /_search
    {
        "query" : {
            "regexp":{
                "<your_field_name_here>": ".+"
            }
        }
    }  

OAuth 2.0 signatures are not required for the actual API calls once the token has been generated. It has only one security token.

OAuth 1.0 requires client to send two security tokens for each API call, and use both to generate the signature. It requires the protected resources endpoints have access to the client credentials in order to validate the request.

Here describes the difference between OAuth 1.0 and 2.0 and how both work.

If you want to prevent the user from enter non-numeric values at the time of enter the information in the TextBox, you can use the Event OnKeyPress like this:

private void txtAditionalBatch_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (!char.IsDigit(e.KeyChar)) e.Handled = true;         //Just Digits
            if (e.KeyChar == (char)8) e.Handled = false;            //Allow Backspace
            if (e.KeyChar == (char)13) btnSearch_Click(sender, e);  //Allow Enter            
        }

This solution doesn't work if the user paste the information in the TextBox using the mouse (right click / paste) in that case you should add an extra validation.

Yes, this is correct, but it looks like a very basic workflow, where you're just buffering changes before they're ready for integration. You should look into more advanced workflows that git supports. You might like the topic branch approach, which lets you work on multiple features in parallel, or the graduation approach which extends your current workflow a bit.

I was having the similar issue when using VirtualBox on Ubuntu 12.04LTS. Now if anyone is using or has ever used Ubuntu, you might be aware that how things are hard sometimes when using shortcut keys in Ubuntu. For me, when i was trying to revert back the Host key, it was just not happening and the shortcut keys won't just work. I even tried the command line option to revert back the scale mode and it won't work either. Finally i found the following when all the other options fails:

Fix the Scale Mode Issue in Oracle VirtualBox in Ubuntu using the following steps:

1. Close all virtual machines and VirtualBox windows.

2. Find your machine config files (i.e. /home/<username>/VirtualBox VMs/ANKSVM) where ANKSVM is your VM Name and edit and change the following in ANKSVM.vbox and ANKSVM.vbox-prev files:

3. Edit the line: <ExtraDataItem name="GUI/Scale" value="on"/> to <ExtraDataItem name="GUI/Scale" value="off"/>

4. Restart VirtualBox

You are done.

This works every time specially when all other options fails like how it happened for me.

Trying to access an undefined variable will throw you a ReferenceError.

A solution to this is to use typeof:

if (typeof window === "undefined") {
  console.log("Oops, `window` is not defined")
}

or a try catch:

try { window } catch (err) {
  console.log("Oops, `window` is not defined")
}

While typeof window is probably the cleanest of the two, the try catch can still be useful in some cases.

You can use this regex /^[a-z0-9]+$/i

If you also need to convert that xml string that comes as a response to the service call, an x object you need can do it as follows:

The results container div has position: relative meaning it is still in the document flow and will change the layout of elements around it. You need to use position: absolute to achieve a 'floating' effect.

You should also check the markup you're using, you have phantom <li>s with no container <ul>, you could probably replace both the div#suggestions and div#autoSuggestionsList with a single <ul> and get the desired result.

You can use java.util.Calendar class to get time in milliseconds. Example:

Calendar cal = Calendar.getInstance();
int milliSec = cal.get(Calendar.MILLISECOND);
// print milliSec

java.util.Date date = cal.getTime();
System.out.println("Output: " +  new SimpleDateFormat("yyyy/MM/dd-HH:mm:ss:SSS").format(date));

You will have to manually delete from the project explorer (your local machine hard drive), then delete the project in IntelliJ when it asks to re-open recent projects.

new Date().toLocaleDateString();

simple as that, just pass your date to js Date Object

array=(z 'b c'); { set "${array[@]}"; printf '%s\n' "$@"; } \
    | sort \
    | mapfile -t array; declare -p array
declare -a array=([0]="b c" [1]="z")

• Open an inline function {...} to get a fresh set of positional arguments (e.g. $1, $2, etc).
• Copy the array to the positional arguments. (e.g. set "${array[@]}" will copy the nth array argument to the nth positional argument. Note the quotes preserve whitespace that may be contained in an array element).
• Print each positional argument (e.g. printf '%s\n' "$@" will print each positional argument on its own line. Again, note the quotes preserve whitespace that may be contained in each positional argument).
• Then sort does its thing.
• Read the stream into an array with mapfile (e.g. mapfile -t array reads each line into the variable array and the -t ignores the \n in each line).
• Dump the array to show its been sorted.

As a function:

set +m
shopt -s lastpipe

sort_array() { 
    declare -n ref=$1
    set "${ref[@]}"
    printf '%s\n' "$@"
    | sort \
    | mapfile -t $ref
}

then

array=(z y x); sort_array array; declare -p array
declare -a array=([0]="x" [1]="y" [2]="z")

I look forward to being ripped apart by all the UNIX gurus! :)

Hello I used this code to have the super user in mysql

GRANT EXECUTE, PROCESS, SELECT, SHOW DATABASES, SHOW VIEW, ALTER, ALTER ROUTINE,
    CREATE, CREATE ROUTINE, CREATE TEMPORARY TABLES, CREATE VIEW, DELETE, DROP,
    EVENT, INDEX, INSERT, REFERENCES, TRIGGER, UPDATE, CREATE USER, FILE,
    LOCK TABLES, RELOAD, REPLICATION CLIENT, REPLICATION SLAVE, SHUTDOWN,
    SUPER
        ON *.* TO mysql@'%'
    WITH GRANT OPTION;

and then

FLUSH PRIVILEGES;

If anyone here is using MySql like I was use this:

CREATE TABLE TempTable AS SELECT * FROM #YourTable; 

ALTER TABLE TempTable 
DROP COLUMN #YourColumn; 

SELECT * FROM TempTable; 
DROP TABLE TempTable;

Since release r59, three.js provides those three functions to rotate a object around object axis.

object.rotateX(angle);
object.rotateY(angle);
object.rotateZ(angle);

Yes, you should be able to set its height and width, as with any element. However, some browsers do not really take these properties into account.

This demo gives an overview of what is possible and how it is displayed in various browsers: https://www.456bereastreet.com/lab/styling-form-controls-revisited/radio-button/

As you'll see, styling radio buttons is not easy :-D

A workaround is to use JavaScript and CSS to replace the radio buttons and other form elements with custom images:

• https://github.com/emblematiq/Niceforms
• https://web.archive.org/web/20161119112447/http://ryanfait.com/resources/custom-checkboxes-and-radio-buttons/

Close the current interpreter using exit() command and reopen typing python to start your work. And do not name a list as list literally. Then you will be fine.

Try this:

$("input[type=checkbox]").prop('checked', true).uniform();

All of the preg_replace() solutions above have issues of single line comments, conditional comments and other pitfalls. I'd recommend taking advantage of the well-tested Minify project rather than creating your own regex from scratch.

In my case I place the following code at the top of a PHP page to minify it:

function sanitize_output($buffer) {
    require_once('min/lib/Minify/HTML.php');
    require_once('min/lib/Minify/CSS.php');
    require_once('min/lib/JSMin.php');
    $buffer = Minify_HTML::minify($buffer, array(
        'cssMinifier' => array('Minify_CSS', 'minify'),
        'jsMinifier' => array('JSMin', 'minify')
    ));
    return $buffer;
}
ob_start('sanitize_output');

If you have <?xml version="1.0" encoding="UTF-8" standalone="yes"?>

but want this: <?xml version="1.0" encoding="UTF-8"?>

Just do:

marshaller.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);
marshaller.setProperty("com.sun.xml.internal.bind.xmlHeaders", "<?xml version=\"1.0\" encoding=\"UTF-8\"?>");

I need to do the same thing for a project I am currently working on. Here is how I solved things:

/* Prompt user for input */
printf("Enter a number: ");

/* Read user input */
char input[255]; //Of course, you can choose a different input size
fgets(input, sizeof(input), stdin);

/* Strip trailing newline */
size_t ln = strlen(input) - 1;
if( input[ln] == '\n' ) input[ln] = '\0';

/* Ensure that input is a number */
for( size_t i = 0; i < ln; i++){
    if( !isdigit(input[i]) ){
        fprintf(stderr, "%c is not a number. Try again.\n", input[i]);
        getInput(); //Assuming this is the name of the function you are using
        return;
    }
}

Answer for "pre-Java-9" is below. As of Java 9, properties files are saved and loaded in UTF-8 by default, but falling back to ISO-8859-1 if an invalid UTF-8 byte sequence is detected. See the Java 9 release notes for details.

Properties files are ISO-8859-1 by definition - see the docs for the Properties class.

Spring has a replacement which can load with a specified encoding, using PropertiesFactoryBean.

EDIT: As Laurence noted in the comments, Java 1.6 introduced overloads for load and store which take a Reader/Writer. This means you can create a reader for the file with whatever encoding you want, and pass it to load. Unfortunately FileReader still doesn't let you specify the encoding in the constructor (aargh) so you'll be stuck with chaining FileInputStream and InputStreamReader together. However, it'll work.

For example, to read a file using UTF-8:

Properties properties = new Properties();
InputStream inputStream = new FileInputStream("path/to/file");
try {
    Reader reader = new InputStreamReader(inputStream, "UTF-8");
    try {
        properties.load(reader);
    } finally {
        reader.close();
    }
} finally {
   inputStream.close();
}

For those who uses Git Bash and having issues with npm run <script>,

Just set npm to use Git Bash to run scripts

npm config set script-shell "C:\\Program Files\\git\\bin\\bash.exe" (change the path according to your installation)

And then npm will run scripts with Git Bash, so such usages like NODE_ENV= will work properly.

I just had the same problem the solution is easy.

You are trying to add an id in the child table that does not exist in the parent table.

check well, because InnoDB has the bug that sometimes increases the auto_increment column without adding values, for example, INSERT ... ON DUPLICATE KEY

import os

def count_files(in_directory):
    joiner= (in_directory + os.path.sep).__add__
    return sum(
        os.path.isfile(filename)
        for filename
        in map(joiner, os.listdir(in_directory))
    )

>>> count_files("/usr/lib")
1797
>>> len(os.listdir("/usr/lib"))
2049

Python 3.5+ introduces %-interpolation (printf-style formatting) for bytes:

>>> b'%d\r\n' % 3
b'3\r\n'

See PEP 0461 -- Adding % formatting to bytes and bytearray.

On earlier versions, you could use str and .encode('ascii') the result:

>>> s = '%d\r\n' % 3
>>> s.encode('ascii')
b'3\r\n'

Note: It is different from what int.to_bytes produces:

>>> n = 3
>>> n.to_bytes((n.bit_length() + 7) // 8, 'big') or b'\0'
b'\x03'
>>> b'3' == b'\x33' != '\x03'
True

In continuing of the Apparently with Laravel 5.2, the closure in DB::listen only receives a single parameter... response above : you can put this code into the Middleware script and use it in the routes.

Additionally:

use Monolog\Logger;
use Monolog\Handler\StreamHandler;

$log = new Logger('sql');
$log->pushHandler(new StreamHandler(storage_path().'/logs/sql-' . date('Y-m-d') . '.log', Logger::INFO));

// add records to the log
$log->addInfo($query, $data);

In VBA we can not use if jj = 5 or 6 then we must use if jj = 5 or jj = 6 then

maybe this:

If inputWks.Range("d9") > 0 And (inputWks.Range("d11") = "Restricted_Expenditure" Or inputWks.Range("d11") = "Unrestricted_Expenditure") Then

Set proper constraint and update delegate methods as:

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

This will resolve dynamic cell height issue. IF not you need to check constraints.

If you want each task to run regardless of any failures, you can do something like:

task :build_all do
  [:debug, :release].each do |t| 
    ts = 0
    begin  
      Rake::Task["build"].invoke(t)
    rescue
      ts = 1
      next
    ensure
      Rake::Task["build"].reenable # If you need to reenable
    end
    return ts # Return exit code 1 if any failed, 0 if all success
  end
end

If you are using Marshmallow, you have to either:

1. Request permissions at runtime (the user will get to allow or deny the request) or:
2. The user must go into Settings -> Apps -> {Your App} -> Permissions and grant storage access.

This is because in Marshmallow, Google completely revamped how permissions work.

Most people responding don't even seem to know what an array pointer is...

The problem is that you do pointer arithmetics with an array pointer: ptr + 1 will mean "jump 5 bytes ahead since ptr points at a 5 byte array".

Do like this instead:

#include <stdio.h>

int main()
{
  char (*ptr)[5];
  char arr[5] = {'a','b','c','d','e'};
  int i;

  ptr = &arr;
  for(i=0; i<5; i++)
  {
    printf("\nvalue: %c", (*ptr)[i]);
  }
}

Take the contents of what the array pointer points at and you get an array. So they work just like any pointer in C.

The issue you are having is common and not explained well in the documentation. Normal devices do not include the sqlite3 database binary which is why you are getting an error. the Android Emeulator, OSX, Linux (if installed) and Windows (after installed) have the binary so you can open a database locally on your machine.

The workaround is to copy the Database from your device to your local machine. This can be accomplished with ADB but requires a number of steps.

Before you start you will need some information:

• path of the SDK (if not included in your OS environment)
• your <package name>, for example, com.example.application
• a <local path> to place your database, eg. ~/Desktop or %userprofile%\Desktop

Next you will need to understand what terminal each command gets written to the first character in the examples below does not get typed but lets you know what shell we are in:

• > = you OS command prompt
• $ = ADB shell command Prompt
• ! = ADB shell as admin command prompt
• %

Next enter the following commands from Terminal or Command (don't enter first character or text in ())

> adb shell
$ su
! cp /data/data/<package name>/Databases/<database name> /sdcard
! exit
$ exit
> adb pull /sdcard/<database name> <local path>
> sqlite3 <local db path>
% .dump
% .exit  (to exit sqldb)

This is a really round about way of copying the database to your local machine and locally reading the database. There are SO and other resources explaining how to install the sqlite3 binary onto your device from an emulator but for one time access this process works.

If you need to access the database interactively I would suggest running your app in an emulator (that already had sqlite3) or installing sqlite onto your devices /xbin path.

I was dealing with same error and after spending time solved it by adding below lines in web.config file

<system.web>
   <httpRuntime targetFramework="4.7.1" maxRequestLength="1048576"/>
</system.web>

and

 <system.webServer>
   <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="1073741824" />
      </requestFiltering>
    </security>
</system.webServer>

Use the %02X format parameter:

printf("%02X",word[i]);

I've just finished a releaseable version of a clientside JS-lib (defiant.js) that does what you're looking for. With defiant.js, you can query a JSON structure with the XPath expressions you're familiar with (no new syntax expressions as in JSONPath).

Example of how it works (see it in browser here http://defiantjs.com/defiant.js/demo/sum.avg.htm):

var data = [
       { "x": 2, "y": 0 },
       { "x": 3, "y": 1 },
       { "x": 4, "y": 1 },
       { "x": 2, "y": 1 }
    ],
    res = JSON.search( data, '//*[ y > 0 ]' );

console.log( res.sum('x') );
// 9
console.log( res.avg('x') );
// 3
console.log( res.min('x') );
// 2
console.log( res.max('x') );
// 4

As you can see, DefiantJS extends the global object JSON with a search function and the returned array is delivered with aggregate functions. DefiantJS contains a few other functionalities but those are out of the scope for this subject. Anywho, you can test the lib with a clientside XPath Evaluator. I think people not familiar with XPath will find this evaluator useful.

In general, this is probably not a great idea, since your html file should only be loading JS files that they actually make use of. Regardless, this would be trivial to do with any server-side scripting language. Just insert the script tags before serving the pages to the client.

If you want to do it without using server-side scripting, you could drop your JS files into a directory that allows listing the directory contents, and then use XMLHttpRequest to read the contents of the directory, and parse out the file names and load them.

Option #3 is to have a "loader" JS file that uses getScript() to load all of the other files. Put that in a script tag in all of your html files, and then you just need to update the loader file whenever you upload a new script.

A mutex is a mutual exclusion object, similar to a semaphore but that only allows one locker at a time and whose ownership restrictions may be more stringent than a semaphore.

It can be thought of as equivalent to a normal counting semaphore (with a count of one) and the requirement that it can only be released by the same thread that locked it^(a).

A semaphore, on the other hand, has an arbitrary count and can be locked by that many lockers concurrently. And it may not have a requirement that it be released by the same thread that claimed it (but, if not, you have to carefully track who currently has responsibility for it, much like allocated memory).

So, if you have a number of instances of a resource (say three tape drives), you could use a semaphore with a count of 3. Note that this doesn't tell you which of those tape drives you have, just that you have a certain number.

Also with semaphores, it's possible for a single locker to lock multiple instances of a resource, such as for a tape-to-tape copy. If you have one resource (say a memory location that you don't want to corrupt), a mutex is more suitable.

Equivalent operations are:

Counting semaphore          Mutual exclusion semaphore
--------------------------  --------------------------
  Claim/decrease (P)                  Lock
  Release/increase (V)                Unlock

Aside: in case you've ever wondered at the bizarre letters used for claiming and releasing semaphores, it's because the inventor was Dutch. Probeer te verlagen means to try and decrease while verhogen means to increase.

^(a) ... or it can be thought of as something totally distinct from a semaphore, which may be safer given their almost-always-different uses.

I don't think there's any need of writing this much big codes.

I've just installed angular-print bower package and all is set to go.

Mine is working awesome .

Arr1 becomes an array of 'Variant' by the first statement of your code:

Dim arr1() As Variant

Array of size zero is not empty, as like an empty box exists in real world.

If you define a variable of 'Variant', that will be empty when it is created.

Following code will display "Empty".

Dim a as Variant

If IsEmpty(a) then
  MsgBox("Empty")
Else
  MsgBox("Not Empty")
End If

Answering the OP questions

A) What do I not understand about how the Google Apps Script console works with respect to printing so that I can see if my code is accomplishing what I'd like?

The code on .gs files of a Google Apps Script project run on the server rather than on the web browser. The way to log messages was to use the Class Logger.

B) Is it a problem with the code?

As the error message said, the problem was that console was not defined but nowadays the same code will throw other error:

ReferenceError: "playerArray" is not defined. (line 12, file "Code")

That is because the playerArray is defined as local variable. Moving the line out of the function will solve this.

var playerArray = [];

function addplayerstoArray(numplayers) {
  for (i=0; i<numplayers; i++) {
    playerArray.push(i);
  }
}  

addplayerstoArray(7);

console.log(playerArray[3])

Now that the code executes without throwing errors, instead to look at the browser console we should look at the Stackdriver Logging. From the Google Apps Script editor UI click on View > Stackdriver Logging.

Addendum

On 2017 Google released to all scripts Stackdriver Logging and added the Class Console, so including something like console.log('Hello world!') will not throw an error but the log will be on Google Cloud Platform Stackdriver Logging Service instead of the browser console.

From Google Apps Script Release Notes 2017

June 23, 2017

Stackdriver Logging has been moved out of Early Access. All scripts now have access to Stackdriver logging.

From Logging > Stackdriver logging

The following example shows how to use the console service to log information in Stackdriver.

function measuringExecutionTime() {
  // A simple INFO log message, using sprintf() formatting.

One other difference lies in the performance.

As the DLL is loaded at runtime by the .exe(s), the .exe(s) and the DLL work with shared memory concept and hence the performance is low relatively to static linking.

On the other hand, a .lib is code that is linked statically at compile time into every process that requests. Hence the .exe(s) will have single memory, thus increasing the performance of the process.

using keep_default_na=False should help you:

df = pd.read_csv(filename, keep_default_na=False)

This can also happen if you have the wrong python27.dll file (in case of Windows), to solve this just re-install (or extract) python with the exact corresponding dll version. I had a similar experience.

If you need all the foreign keys of the user then use the following script

SELECT a.constraint_name, a.table_name, a.column_name,  c.owner, 
       c_pk.table_name r_table_name,  b.column_name r_column_name
  FROM user_cons_columns a
  JOIN user_constraints c ON a.owner = c.owner
       AND a.constraint_name = c.constraint_name
  JOIN user_constraints c_pk ON c.r_owner = c_pk.owner
       AND c.r_constraint_name = c_pk.constraint_name
  JOIN user_cons_columns b ON C_PK.owner = b.owner
       AND  C_PK.CONSTRAINT_NAME = b.constraint_name AND b.POSITION = a.POSITION     
 WHERE c.constraint_type = 'R'

Stuart's answer provides a great explanation, but I'd like to provide another example.

I ran into this issue when attempting to perform a reduce on a Stream containing null values (actually it was LongStream.average(), which is a type of reduction). Since average() returns OptionalDouble, I assumed the Stream could contain nulls but instead a NullPointerException was thrown. This is due to Stuart's explanation of null v. empty.

So, as the OP suggests, I added a filter like so:

list.stream()
    .filter(o -> o != null)
    .reduce(..);

Or as tangens pointed out below, use the predicate provided by the Java API:

list.stream()
    .filter(Objects::nonNull)
    .reduce(..);

From the mailing list discussion Stuart linked: Brian Goetz on nulls in Streams

Comparable defines a natural ordering. What this means is that you're defining it when one object should be considered "less than" or "greater than".

Suppose you have a bunch of integers and you want to sort them. That's pretty easy, just put them in a sorted collection, right?

TreeSet<Integer> m = new TreeSet<Integer>(); 
m.add(1);
m.add(3);
m.add(2);
for (Integer i : m)
... // values will be sorted

But now suppose I have some custom object, where sorting makes sense to me, but is undefined. Let's say, I have data representing districts by zipcode with population density, and I want to sort them by density:

public class District {
  String zipcode; 
  Double populationDensity;
}

Now the easiest way to sort them is to define them with a natural ordering by implementing Comparable, which means there's a standard way these objects are defined to be ordered.:

public class District implements Comparable<District>{
  String zipcode; 
  Double populationDensity;
  public int compareTo(District other)
  {
    return populationDensity.compareTo(other.populationDensity);
  }
}

Note that you can do the equivalent thing by defining a comparator. The difference is that the comparator defines the ordering logic outside the object. Maybe in a separate process I need to order the same objects by zipcode - in that case the ordering isn't necessarily a property of the object, or differs from the objects natural ordering. You could use an external comparator to define a custom ordering on integers, for example by sorting them by their alphabetical value.

Basically the ordering logic has to exist somewhere. That can be -

• in the object itself, if it's naturally comparable (extends Comparable -e.g. integers)

• supplied in an external comparator, as in the example above.

It's very simple. You are getting the result into an Object which is a primitive one.

Your code:

Object result = (Object)envelope.getResponse();

Correct code:

SoapObject result=(SoapObject)envelope.getResponse();

//To get the data.
String resultData=result.getProperty(0).toString();
// 0 is the first object of data.

I think this should definitely work.

You can always disable security, then go in and re-enable it with the settings you want.

simplifying the general answer

SQL Case Sensitive String Compare

These examples may be helpful:

Declare @S1 varchar(20) = 'SQL'
Declare @S2 varchar(20) = 'sql'

  
if @S1 = @S2 print 'equal!' else print 'NOT equal!' -- equal (default non-case sensitivity for SQL

if cast(@S1 as binary) = cast(Upper(@S2) as binary) print 'equal!' else print 'NOT equal!' -- equal

if cast(@S1 as binary) = cast(@S2 as binary) print 'equal!' else print 'NOT equal!' -- not equal

if  @S1 COLLATE Latin1_General_CS_AS  = Upper(@S2) COLLATE Latin1_General_CS_AS  print 'equal!' else print 'NOT equal!' -- equal

if  @S1 COLLATE Latin1_General_CS_AS  = @S2 COLLATE Latin1_General_CS_AS  print 'equal!' else print 'NOT equal!' -- not equal

 

The convert is probably more efficient than something like runtime calculation of hashbytes, and I'd expect the collate may be even faster.

Simple function. Transform strings like 'Ábç Éfg' to 'abc_efg'

/**
 * @param $str
 * @return mixed
 */
function sanitizeString($str) {
    $str = preg_replace('/[áàãâä]/ui', 'a', $str);
    $str = preg_replace('/[éèêë]/ui', 'e', $str);
    $str = preg_replace('/[íìîï]/ui', 'i', $str);
    $str = preg_replace('/[óòõôö]/ui', 'o', $str);
    $str = preg_replace('/[úùûü]/ui', 'u', $str);
    $str = preg_replace('/[ç]/ui', 'c', $str);
    $str = preg_replace('/[^a-z0-9]/i', '_', $str);
    $str = preg_replace('/_+/', '_', $str);

    return $str;
}

They way I did it was by selecting all of the data

select * from myTable and then right-clicking on the result set and chose "Save results as..." a csv file.

Opening the csv file in Notepad++ I saw the LF characters not visible in SQL Server result set.

Either as most people answered: the file doesn't exist / you're not specifying the path correctly.

Or, you're simply writing the syntax wrong (which you can't know unless you know what it should be like, right?, especially when in the "help" itself, it's wrong).

For gnuplot 4.6.0 on windows 7, terminal type set to windows

Make sure you specify the file's whole path to avoid looking for it where it's not (default seems to be "documents")

Make sure you use this syntax:

plot 'path\path\desireddatafile.txt'

NOT

plot "< path\path\desireddatafile.txt>"

NOR

plot "path\path\desireddatafile.txt"

also make sure your file is in the right format, like for .txt file format ANSI, not Unicode and such.

The application name come from getContextPath.

I find this graphic from Agile Software Craftsmanship HttpServletRequest Path Decoding sorts out all the different methods that are available:

If I understand the question correctly, he needs to perform a REST GET action, but wonders if it's OK to send in data via HTTP POST method.

As Scott had nicely laid out in his answer earlier, there are many good reasons to POST input data. IMHO it should be done this way, if quality of solution is the top priority.

A while back we created an REST API to authenticate users, taking username/password and returning an access token. The API is encrypted under TLS, but exposed to public internet. After evaluating different options, we chose HTTP POST for the REST method of "GET access token," because that's the only way to meet security standards.

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

In [56]: import random, numpy

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

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

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

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

import numpy, timeit, random

a, b = 1, 3

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

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

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

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

The numpy version is over 60 times faster.

2. Then I modified /etc/apache2/apache2.conf, and I put the permissions for localhost, and my mobile, this time I used the IP address, I know it is not completely safe, but it's OK for my purposes.

With Hibernate's NativeQuery, you need to return a ResultList instead of a SingleResult, because Hibernate modifies a native query

INSERT INTO bla (a,b) VALUES (2,3) RETURNING id

like

INSERT INTO bla (a,b) VALUES (2,3) RETURNING id LIMIT 1

if you try to get a single result, which causes most databases (at least PostgreSQL) to throw a syntax error. Afterwards, you may fetch the resulting id from the list (which usually contains exactly one item).

So it is very easy to disable any button in react native

<TouchableOpacity disabled={true}>
    <Text> 
          This is disabled button
   </Text>
</TouchableOpacity>

disabled is a prop in react native and when you set its value to "true" it will disable your button

Here a one-file solution (based on elegant answer by @Marcin:

#include <iostream>

#define ENUM_TXT \
X(Red) \
X(Green) \
X(Blue) \
X(Cyan) \
X(Yellow) \
X(Magenta) \

enum Colours {
#   define X(a) a,
ENUM_TXT
#   undef X
    ColoursCount
};

char const* const colours_str[] = {
#   define X(a) #a,
ENUM_TXT
#   undef X
    0
};

std::ostream& operator<<(std::ostream& os, enum Colours c)
{
    if (c >= ColoursCount || c < 0) return os << "???";
    return os << colours_str[c] << std::endl;
}

int main()
{
    std::cout << Red << Blue << Green << Cyan << Yellow << Magenta << std::endl;
}

It checks if the modulo of the division. For example, in the case you are iterating over all numbers from 2 to n and checking if n is divisible by any of the numbers in between. Simply put, you are checking if a given number n is prime. (Hint: You could check up to n/2).

There are two answers above up-to-now and they are both long (and tl;dr too short IMHO), so I write summary from my experience starting to use new java.time library (applicable as noted in other answers to Java version 8+). ISO 8601 sets standard way to write dates: YYYY-MM-DD so the format of date-time is only as below (could be 0, 3, 6 or 9 digits for milliseconds) and no formatting string necessary:

import java.time.Instant;
public static void main(String[] args) {
    String date="2010-10-02T12:23:23Z";
    try {
        Instant myDate = Instant.parse(date);
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

I did not need it, but as getting year is in code from the question, then:
it is trickier, cannot be done from Instant directly, can be done via Calendar in way of questions Get integer value of the current year in Java and Converting java.time to Calendar but IMHO as format is fixed substring is more simple to use:

myDate.toString().substring(0,4);

Have you try sudo git push -u origin --all? Sometimes it's the only thing you need to avoid this problem. It asks you for the admin system password - the one you can make login to your machine -, and that's what you need to push - or commit, if it is the case.

What you're looking for is n choose k. Basically:

For every pair of 100 items, you'd have 4,950 combinations - provided order doesn't matter (AB and BA are considered a single combination) and you don't want to repeat (AA is not a valid pair).

The only code that have worked for me:

childFrame.setAlwaysOnTop(true);

This code should be called on the main/parent frame before making the child/modal frame visible. Your child/modal frame should also have this code:

parentFrame.setFocusableWindowState(false);
this.mainFrame.setEnabled(false);

Compile means that you need the JAR for compiling and running the app. For a web application, as an example, the JAR will be placed in the WEB-INF/lib directory.

Provided means that you need the JAR for compiling, but at run time there is already a JAR provided by the environment so you don't need it packaged with your app. For a web app, this means that the JAR file will not be placed into the WEB-INF/lib directory.

For a web app, if the app server already provides the JAR (or its functionality), then use "provided" otherwise use "compile".

Here is the reference.

I'd recommend using ActiveRecord::Base.connection.exec_query instead of ActiveRecord::Base.connection.execute which returns a ActiveRecord::Result (available in rails 3.1+) which is a bit easier to work with.

Then you can access it in various the result in various ways like .rows, .each, or .to_hash

From the docs:

result = ActiveRecord::Base.connection.exec_query('SELECT id, title, body FROM posts')
result # => #<ActiveRecord::Result:0xdeadbeef>


# Get the column names of the result:
result.columns
# => ["id", "title", "body"]

# Get the record values of the result:
result.rows
# => [[1, "title_1", "body_1"],
      [2, "title_2", "body_2"],
      ...
     ]

# Get an array of hashes representing the result (column => value):
result.to_hash
# => [{"id" => 1, "title" => "title_1", "body" => "body_1"},
      {"id" => 2, "title" => "title_2", "body" => "body_2"},
      ...
     ]

# ActiveRecord::Result also includes Enumerable.
result.each do |row|
  puts row['title'] + " " + row['body']
end

<source src="http://serverIP_or_domain/location_of_video.mp4" type="video/mp4">

Here is my strategy to solve the problem.

Problem Statement

We need to make changes in more than 10 files. We tried PULL (git pull origin master), but Git shouted:

error: Your local changes to the following files would be overwritten by merge: Please, commit your changes or stash them before you can merge.

We tried to execute commit and then pull, but they didn't work either.

Solution

We were in the dirty stage actually, because the files were in the "Staging Area" a.k.a "Index Area" and some were in the "Head Area" a.k.a "local Git directory". And we wanted to pull the changes from the server.

Check this link for information about different stages of Git in a clear manner: GIT Stages

We followed the following steps

• git stash (this made our working directory clean. Your changes are stored on the stack by Git).
• git pull origin master (Pull the changes from the server)
• git stash apply (Applied all the changes from stack)
• git commit -m 'message' (Committed the changes)
• git push origin master (Pushed the changes to the server)
• git stash drop (Drop the stack)

Let's understand when and why you need stashing

If you are in the dirty state, means you are making changes in your files and then you are compelled, due to any reason, to pull or switch to another branch for some very urgent work, so at this point you can't pull or switch until you commit your change. The stash command is here as a helping hand.

From the book ProGIT, 2nd Edition:

Often, when you’ve been working on part of your project, things are in a messy state and you want to switch branches for a bit to work on something else. The problem is, you don’t want to do a commit of half-done work just so you can get back to this point later. The answer to this issue is the git stash command. Stashing takes the dirty state of your working directory – that is, your modified tracked files and staged changes – and saves it on a stack of unfinished changes that you can reapply at any time.

To push all your branches, use either (replace REMOTE with the name of the remote, for example "origin"):

git push REMOTE '*:*'
git push REMOTE --all

To push all your tags:

git push REMOTE --tags

Finally, I think you can do this all in one command with:

git push REMOTE --mirror

However, in addition --mirror, will also push your remotes, so this might not be exactly what you want.

You could use %g to achieve this:

'%g'%(3.140)

or, with Python = 2.6:

'{0:g}'.format(3.140)

From the docs for format: g causes (among other things)

insignificant trailing zeros [to be] removed from the significand, and the decimal point is also removed if there are no remaining digits following it.

Between the deprecation of mutation events and the emergence of MutationObserver, an efficent way to be notified when a specific element was added to the DOM was to exploit CSS3 animation events.

To quote the blog post:

Setup a CSS keyframe sequence that targets (via your choice of CSS selector) whatever DOM elements you want to receive a DOM node insertion event for. I used a relatively benign and little used css property, clip I used outline-color in an attempt to avoid messing with intended page styles – the code once targeted the clip property, but it is no longer animatable in IE as of version 11. That said, any property that can be animated will work, choose whichever one you like.

Next I added a document-wide animationstart listener that I use as a delegate to process the node insertions. The animation event has a property called animationName on it that tells you which keyframe sequence kicked off the animation. Just make sure the animationName property is the same as the keyframe sequence name you added for node insertions and you’re good to go.

I had something similar this evening which was driving me batty. Submitting a form was giving me the values in $_REQUEST but not in $_POST.

Eventually I noticed that there were actually two requests going through on the network tab in firebug; first a POST with a 301 response, then a GET with a 200 response.

Hunting about the interwebs it sounded like most people thought this was to do with mod_rewrite causing the POST request to redirect and thus change to a GET.

In my case it wasn't mod_rewrite to blame, it was something far simpler... my URL for the POST also contained a GET query string which was starting without a trailing slash on the URL. It was this causing apache to redirect.

Spot the difference...

Bad: http://blah.de.blah/my/path?key=value&otherkey=othervalue
Good: http://blah.de.blah/my/path/?key=value&otherkey=othervalue

The bottom one doesn't cause a redirect and gives me $_POST!

The compilation problem only occurs for me (gcc 4.3, ubuntu 8.10) if the three variables are global. The problem is that C doesn't work like a script languages, so you cannot take for granted that the initialization of u and t occur after the one of s. That's why you get a compilation error. Now, you cannot initialize t and y they way you did it before, that's why you will need a char*. The code that do the work is the following:

#include <stdio.h>
#include <stdlib.h>

#define STR "ABCD"

const char s[] = STR;
char* t;
char* u;

void init(){
    t = malloc(sizeof(STR)-1);
    t[0] = s[0];
    t[1] = s[1];
    t[2] = s[2];
    t[3] = s[3];


    u = malloc(sizeof(STR)-1);
    u[0] = s[3];
    u[1] = s[2];
    u[2] = s[1];
    u[3] = s[0];
}

int main(void) {
    init();
    puts(t);
    puts(u);

    return EXIT_SUCCESS;
}

EDIT: Look at the comments and other answers. There are smarter answers than this one! Or try to improve this one as community wiki.

Models do not register themselves to a master object, so no, Rails does not have the list of models.

But you could still look in the content of the models directory of your application...

Dir.foreach("#{RAILS_ROOT}/app/models") do |model_path|
  # ...
end

EDIT: Another (wild) idea would be to use Ruby reflection to search for every classes that extends ActiveRecord::Base. Don't know how you can list all the classes though...

EDIT: Just for fun, I found a way to list all classes

Module.constants.select { |c| (eval c).is_a? Class }

EDIT: Finally succeeded in listing all models without looking at directories

Module.constants.select do |constant_name|
  constant = eval constant_name
  if not constant.nil? and constant.is_a? Class and constant.superclass == ActiveRecord::Base
    constant
  end
end

If you want to handle derived class too, then you will need to test the whole superclass chain. I did it by adding a method to the Class class:

class Class
  def extend?(klass)
    not superclass.nil? and ( superclass == klass or superclass.extend? klass )
  end
end

def models 
  Module.constants.select do |constant_name|
    constant = eval constant_name
    if not constant.nil? and constant.is_a? Class and constant.extend? ActiveRecord::Base
    constant
    end
  end
end

Angular doesn't come with an orderBy filter out of the box, but if we decide we need one we can easily make one. There are however some caveats we need to be aware of to do with speed and minification. See below.

A simple pipe would look something like this.

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name: 'sort'
})
export class SortPipe implements PipeTransform {
  transform(ary: any, fn: Function = (a,b) => a > b ? 1 : -1): any {
    return ary.sort(fn)
  }
}

This pipe accepts a sort function (fn), and gives it a default value that will sort an array of primitives in a sensible way. We have the option of overriding this sort function if we wish.

It does not accept an attribute name as a string, because attribute names are subject to minification. They will change when we minify our code, but minifiers are not smart enough to also minify the value in the template string.

Sorting primitives (numbers and strings)

We could use this to sort an array of numbers or strings using the default comparator:

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

@Component({
  selector: 'cat',
  template: `
    {{numbers | sort}}
    {{strings | sort}}
  `
})
export class CatComponent
  numbers:Array<number> = [1,7,5,6]
  stringsArray<string> = ['cats', 'hats', 'caveats']
}

Sorting an array of objects

If we want to sort an array of objects, we can give it a comparator function.

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

@Component({
  selector: 'cat',
  template: `
    {{cats | sort:byName}}
  `
})
export class CatComponent
  cats:Array<Cat> = [
    {name: "Missy"},
    {name: "Squoodles"},
    {name: "Madame Pompadomme"}
  ]
  byName(a,b) {
    return a.name > b.name ? 1 : -1
  }
}

Caveats - pure vs. impure pipes

Angular 2 has a concept of pure and impure pipes.

A pure pipe optimises change detection using object identity. This means that the pipe will only run if the input object changes identity, for example if we add a new item to the array. It will not descent into objects. This means that if we change a nested attribute: this.cats[2].name = "Fluffy" for example, the pipe will not rerun. This helps Angular to be fast. Angular pipes are pure by default.

An impure pipe on the other hand will check object attributes. This potentially makes it much slower. Because it can't guarantee what the pipe function will do (perhaps it sortd differently based on the time of day for example), an impure pipe will run every time an asynchronous event occurs. This will slow down your app considerably if the array is large.

The pipe above is pure. This means it will only run when the objects in the array are immutable. If you change a cat, you must replace the entire cat object with a new one.

this.cats[2] = {name:"Tomy"}

We can change the above to an impure pipe by setting the pure attribute:

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name: 'sort',
  pure: false
})
export class SortPipe implements PipeTransform {
  transform(ary: any, fn: Function = (a,b) => a > b ? 1 : -1): any {
    return ary.sort(fn)
  }
}

This pipe will descend into objects, but will be slower. Use with caution.

Swift 4:

First create an outlet for your UIImageView

@IBOutlet var infoImage: UIImageView!

Then use the image property in UIImageView

infoImage.image = UIImage(named: "icons8-info-white")

iOS13+ //top Most view Controller

extension UIViewController {
    func topMostViewController() -> UIViewController {
        if self.presentedViewController == nil {
            return self
        }
        if let navigation = self.presentedViewController as? UINavigationController {
            return navigation.visibleViewController!.topMostViewController()
        }
        if let tab = self.presentedViewController as? UITabBarController {
            if let selectedTab = tab.selectedViewController {
                return selectedTab.topMostViewController()
            }
            return tab.topMostViewController()
        }
        return self.presentedViewController!.topMostViewController()
    }
}

extension UIApplication {
    func topMostViewController() -> UIViewController? {
        return UIWindow.key!.rootViewController?.topMostViewController()
    }
}

extension UIWindow {
    static var key: UIWindow? {
        if #available(iOS 13, *) {
            return UIApplication.shared.windows.first { $0.isKeyWindow }
        } else {
            return UIApplication.shared.keyWindow
        }
    }
}

//use let vc = UIApplication.shared.topMostViewController()

// End top Most view Controller

This worked like a charm for me, of-course it requires super-user privileges :-)

# hcitool cc <target-bdaddr>; hcitool auth <target-bdaddr>

To get <target-bdaddr> you may issue below command:
$ hcitool scan

Note: Exclude # & $ as they are command line prompts.

If you have msi installer open it with Orca (tool from Microsoft), table Property (rows UpgradeCode, ProductCode, Product version etc) or table Upgrade column Upgrade Code.

Try to find instller via registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall find required subkey and watch value InstallSource. Maybe along the way you'll be able to find the MSI file.

If a class, or anything derived from it, might hold the last live reference to an object with a finalizer, then either GC.SuppressFinalize(this) or GC.KeepAlive(this) should be called on the object after any operation that might be adversely affected by that finalizer, thus ensuring that the finalizer won't run until after that operation is complete.

The cost of GC.KeepAlive() and GC.SuppressFinalize(this) are essentially the same in any class that doesn't have a finalizer, and classes that do have finalizers should generally call GC.SuppressFinalize(this), so using the latter function as the last step of Dispose() may not always be necessary, but it won't be wrong.

When I write programs, during initialization, I usually spin off a thread for error handling, and initialize a special structure for errors, including a lock. Then, when I detect an error, through return values, I enter in the info from the exception into the structure and send a SIGIO to the exception handling thread, then see if I can't continue execution. If I can't, I send a SIGURG to the exception thread, which stops the program gracefully.

@jmetz's answer is probably the one most people need; however it yields a one-dimensional array, e.g. making it unusable to remove entire rows or columns in matrices.

To do so, one should reduce the logical array to one dimension, then index the target array. For instance, the following will remove rows which have at least one NaN value:

x = x[~numpy.isnan(x).any(axis=1)]

See more detail here.

add this in web.config file

           <configuration>
              <appSettings>
                 <add key="ConnectionString" value="Your connection string which contains database id and password"/>
            </appSettings>
            </configuration>

.cs file

 public ConnectionObjects()
 {           
    string connectionstring= ConfigurationManager.AppSettings["ConnectionString"].ToString();
 }

Hope this helps.

My favorite is (:A..:Z).to_a.shuffle[0,8].join. Note that shuffle requires Ruby > 1.9.

Use OOP concept instead. Create a class with function

class MyClass {

...

function getData($query) {
    $result = mysqli_query($this->conn, $query);
    while($row=mysqli_fetch_assoc($result)) {
        $resultset[] = $row;
    }       
    if(!empty($resultset))
        return $resultset;
} }

and then use the class object to call function in your code

<?php 

    $obj = new MyClass();
    $row = $obj->getData("select city_name from city"); 
?>
<select>
    <?php foreach($row as $row){ ?>
        <option><?php echo $row['city_name'] ?></option>

<?php  } ?>
</select>

i have never done this, but it would be done like this:

var script = $('#google').attr("onclick")

If you declare it like

int x;

in a header file which is then included in multiple places, you'll end up with multiple instances of x (and potentially compile or link problems).

The correct way to approach this is to have the header file say

extern int x; /* declared in foo.c */

and then in foo.c you can say

int x; /* exported in foo.h */

THen you can include your header file in as many places as you like.

If you have a plist of devices (eg maintained by @Tib above in https://stackoverflow.com/a/17655825/849616) to handle it if Swift 3 you'd use:

extension UIDevice {
    /// Fetches the information about the name of the device.
    ///
    /// - Returns: Should return meaningful device name, if not found will return device system code.
    public static func modelName() -> String {
        let physicalName = deviceSystemCode()
        if let deviceTypes = deviceTypes(), let modelName = deviceTypes[physicalName] as? String {
            return modelName
        }
        return physicalName
    }
}

private extension UIDevice {
    /// Fetches from system the code of the device
    static func deviceSystemCode() -> String {
        var systemInfo = utsname()
        uname(&systemInfo)
        let machineMirror = Mirror(reflecting: systemInfo.machine)
        let identifier = machineMirror.children.reduce("") { identifier, element in
            guard let value = element.value as? Int8, value != 0 else { return identifier }
            return identifier + String(UnicodeScalar(UInt8(value)))
        }
        return identifier
    }

    /// Fetches the plist entries from plist maintained in https://stackoverflow.com/a/17655825/849616
    ///
    /// - Returns: A dictionary with pairs of deviceSystemCode <-> meaningfulDeviceName.
    static func deviceTypes() -> NSDictionary? {
        if let fileUrl = Bundle.main.url(forResource: "your plist name", withExtension: "plist"),
            let configurationDictionary = NSDictionary(contentsOf: fileUrl) {
            return configurationDictionary
        }
        return nil
    }
}

Later you can call it using UIDevice.modelName().

Additional credits go to @Tib (for plist), @Aniruddh Joshi (for deviceSystemCode() function).

You can also use Eclipse's keyboard shortcuts: just go to menu Preferences ? keymap and choose Eclipse from the dropdown menu.

The actual path is: menu File ? Settings ? Keymap (under IDE settings)

• Ctrl + Home = Jump to start of file
• Ctrl + End = Jump to end of file

I think it is confusing to think of it in terms of negative numbers. Since it is a logarithm think of the negative values the same way you think of powers of ten. 10^3 = 1000 while 10^-3 = 0.001.

With this in mind and using the formulas from S Lists's answer (and assuming our base power is 1mW in all these cases) we can build a little table:

|--------|-------------------|
| P(dBm) |        P(mW)      |
|--------|-------------------|
|    50  |  100000           |    
|    40  |   10000           |    strong transmitter
|    30  |    1000           |             ^  
|    20  |     100           |             |
|    10  |      10           |             |
|     0  |       1           |
|   -10  |       0.1         |
|   -20  |       0.01        |
|   -30  |       0.001       |
|   -40  |       0.0001      |
|   -50  |       0.00001     |             |
|   -60  |       0.000001    |             |
|   -70  |       0.0000001   |             v
|   -80  |       0.00000001  |    sensitive receiver
|   -90  |       0.000000001 |
|--------|-------------------|

When I think of it like this I find that it's easier to see that the more negative the dBm value then the farther to the right of the decimal the actual power value is.

When it comes to mobile networks, it not so much that they aren't powerful enough, rather it is that they are more sensitive. When you see receivers specs with dBm far into the negative values, then what you are seeing is more sensitive equipment.

Normally you would want your transmitter to be powerful (further in to the positives) and your receiver to be sensitive (further in to the negatives).

There aren't any selector hacks for IE8. The best resource for this issue is http://browserhacks.com/#ie

If you want to target specific IE8 you should do comment in html

<!--[if IE 8]> Internet Explorer 8 <![endif]-->

or you could use attribute hacks like:

/* IE6, IE7, IE8, but also IE9 in some cases :( */
#diecinueve { color: blue\9; }

/* IE7, IE8 */
#veinte { color/*\**/: blue\9; }

/* IE8, IE9 */
#anotherone  {color: blue\0/;} /* must go at the END of all rules */

In my case below command worked for windows. It will install latest required version between 3.1.1 and 3.2.0. Depending on OS use either double or single quotes

npm install typescript@">=3.1.1 <3.2.0" 

Getting a product key is free. Here is how I did it:

I just downloaded the 2012 Express install ISO image. After install I got the message "This product will expire in 30 day(s). Registration is required for the continued use of Microsoft Visual Studio Express 2012 for Web."

On that same screen is a register online link. Clicking that I signed in with my live account, updated my profile, and got a registration key.

To link from a page to another section of the page, I navigate through the page depending on the page's location to the other, at the URL bar, and add the #id. So what I mean;

<a href = "../#the_part_that_you_want">This takes you #the_part_that_you_want at the page before</a>

I would suggest the use of MySQLi or MySQL PDO for performance and security purposes, but to answer the question:

while($row = mysql_fetch_assoc($result)){
     $json[] = $row;
}

echo json_encode($json);

If you switched to MySQLi you could do:

$query = "SELECT * FROM table";
$result = mysqli_query($db, $query);

$json = mysqli_fetch_all ($result, MYSQLI_ASSOC);
echo json_encode($json );

If you're using SQL Management Studio, please goto connection properties and click on "Trust server certificated"

For the problem you're having about the batch file asking the user if the destination is a folder or file, if you know the answer in advance, you can do as such:

If destination is a file: echo f | [batch file path]

If folder: echo d | [batch file path]

It will essentially just pipe the letter after "echo" to the input of the batch file.

This would do

string x = TextBoxD1.Text;
int xi = Convert.ToInt32(x);

Or you can use

int xi = Int32.Parse(x);

I used this solution to set the file name:

HTML:

<a href="#" id="downloader" onclick="download()" download="image.png">Download!</a>
<canvas id="canvas"></canvas>

JavaScript:

function download(){
    document.getElementById("downloader").download = "image.png";
    document.getElementById("downloader").href = document.getElementById("canvas").toDataURL("image/png").replace(/^data:image\/[^;]/, 'data:application/octet-stream');
}

For example, like this:

const querystring = require('querystring');
const https = require('https');

var postData = querystring.stringify({
    'msg' : 'Hello World!'
});

var options = {
  hostname: 'posttestserver.com',
  port: 443,
  path: '/post.php',
  method: 'POST',
  headers: {
       'Content-Type': 'application/x-www-form-urlencoded',
       'Content-Length': postData.length
     }
};

var req = https.request(options, (res) => {
  console.log('statusCode:', res.statusCode);
  console.log('headers:', res.headers);

  res.on('data', (d) => {
    process.stdout.write(d);
  });
});

req.on('error', (e) => {
  console.error(e);
});

req.write(postData);
req.end();

If you are using (org.springframework.jdbc.datasource.DriverManagerDataSource) in ApplicationContext.xml to specify Database details then use below simple property to specify the schema.

<property name="schema" value="schemaName" />

Check the syntax of your connection string in the web.config. It should be something like ConnectionString="Data Source=C:\DataDictionary\NerdDinner.sdf"

Little late to the party. But I thought this is more helpful for who would like to learn (or have clarity) on developing Angular JS Custom Services using factory, service and provider methodologies.

I came across this video which explains clearly about factory, service and provider methodologies for developing AngularJS Custom Services:

https://www.youtube.com/watch?v=oUXku28ex-M

Source Code: http://www.techcbt.com/Post/353/Angular-JS-basics/how-to-develop-angularjs-custom-service

Code posted here is copied straight from the above source, to benefit readers.

The code for "factory" based custom service is as follows (which goes with both sync and async versions along with calling http service):

var app = angular.module("app", []);_x000D_
app.controller('emp', ['$scope', 'calcFactory',_x000D_
  function($scope, calcFactory) {_x000D_
    $scope.a = 10;_x000D_
    $scope.b = 20;_x000D_
_x000D_
    $scope.doSum = function() {_x000D_
      //$scope.sum = calcFactory.getSum($scope.a, $scope.b); //synchronous_x000D_
      calcFactory.getSum($scope.a, $scope.b, function(r) { //aynchronous_x000D_
        $scope.sum = r;_x000D_
      });_x000D_
    };_x000D_
_x000D_
  }_x000D_
]);_x000D_
_x000D_
app.factory('calcFactory', ['$http', '$log',_x000D_
  function($http, $log) {_x000D_
    $log.log("instantiating calcFactory..");_x000D_
    var oCalcService = {};_x000D_
_x000D_
    //oCalcService.getSum = function(a,b){_x000D_
    // return parseInt(a) + parseInt(b);_x000D_
    //};_x000D_
_x000D_
    //oCalcService.getSum = function(a, b, cb){_x000D_
    // var s = parseInt(a) + parseInt(b);_x000D_
    // cb(s);_x000D_
    //};_x000D_
_x000D_
    oCalcService.getSum = function(a, b, cb) { //using http service_x000D_
_x000D_
      $http({_x000D_
        url: 'http://localhost:4467/Sum?a=' + a + '&b=' + b,_x000D_
        method: 'GET'_x000D_
      }).then(function(resp) {_x000D_
        $log.log(resp.data);_x000D_
        cb(resp.data);_x000D_
      }, function(resp) {_x000D_
        $log.error("ERROR occurred");_x000D_
      });_x000D_
    };_x000D_
_x000D_
    return oCalcService;_x000D_
  }_x000D_
]);

The code for "service" methodology for Custom Services (this is pretty similar to 'factory', but different from syntax point of view):

var app = angular.module("app", []);_x000D_
app.controller('emp', ['$scope', 'calcService', function($scope, calcService){_x000D_
 $scope.a = 10;_x000D_
 $scope.b = 20;_x000D_
_x000D_
 $scope.doSum = function(){_x000D_

The code for "provider" methodology for Custom Services (this is necessary, if you would like to develop service which could be configured):

var app = angular.module("app", []);_x000D_
app.controller('emp', ['$scope', 'calcService', function($scope, calcService){_x000D_
 $scope.a = 10;_x000D_

   $scope.sum = r;_x000D_
  });  _x000D_
 };_x000D_
_x000D_
}]);_x000D_
_x000D_
app.provider('calcService', function(){_x000D_
_x000D_
 var baseUrl = '';_x000D_
_x000D_

Finally the UI which works with any of the above services:

<html>_x000D_
<head>_x000D_
 <title></title>_x000D_
 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js" ></script>_x000D_
 <script type="text/javascript" src="t03.js"></script>_x000D_
</head>_x000D_
<body ng-app="app">_x000D_
 <div ng-controller="emp">_x000D_
  <div>_x000D_
   Value of a is {{a}},_x000D_
   but you can change_x000D_
   <input type=text ng-model="a" /> <br>_x000D_
_x000D_
   Value of b is {{b}},_x000D_
   but you can change_x000D_
   <input type=text ng-model="b" /> <br>_x000D_
_x000D_
  </div>_x000D_
  Sum = {{sum}}<br>_x000D_
  <button ng-click="doSum()">Calculate</button>_x000D_
 </div>_x000D_
</body>_x000D_
</html>

You have to make classpath in pom file for your dependency. Therefore you have to copy all the dependencies into one place.

Check my blog.

I am using a com.google.android.material.bottomnavigation.BottomNavigationView (not the same as OP's) and I tried a variety of the suggested solutions above, but the only thing that worked was setting app:itemBackground and app:itemIconTint to my selector color worked for me.

        <com.google.android.material.bottomnavigation.BottomNavigationView
            style="@style/BottomNavigationView"
            android:foreground="?attr/selectableItemBackground"
            android:theme="@style/BottomNavigationView"
            app:itemBackground="@color/tab_color"
            app:itemIconTint="@color/tab_color"
            app:itemTextColor="@color/bottom_navigation_text_color"
            app:labelVisibilityMode="labeled"
            app:menu="@menu/bottom_navigation" />

My color/tab_color.xml uses android:state_checked

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/grassSelected" android:state_checked="true" />
    <item android:color="@color/grassBackground" />
</selector>

and I am also using a selected state color for color/bottom_navigation_text_color.xml

Not totally relevant here but for full transparency, my BottomNavigationView style is as follows:

    <style name="BottomNavigationView" parent="Widget.Design.BottomNavigationView">
        <item name="android:layout_width">match_parent</item>
        <item name="android:layout_height">@dimen/bottom_navigation_height</item>
        <item name="android:layout_gravity">bottom</item>
        <item name="android:textSize">@dimen/bottom_navigation_text_size</item>
    </style>

You have to actually call some method to create the directories. Just creating a file object will not create the corresponding file or directory on the file system.

You can use File#mkdirs() method to create the directory: -

theFile.mkdirs();

Difference between File#mkdir() and File#mkdirs() is that, the later will create any intermediate directory if it does not exist.

You could use Levenshtein distance to calculate the difference between two strings. http://en.wikipedia.org/wiki/Levenshtein_distance

you can use these methods

import android.text.Editable
import android.text.TextWatcher
import android.widget.EditText
import android.widget.TextView
import java.text.NumberFormat
import java.util.*

fun TextView.currencyFormat() {
    addTextChangedListener(object : TextWatcher {
        override fun afterTextChanged(s: Editable?) {}

        override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {}

        override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {
            removeTextChangedListener(this)
            text = if (s?.toString().isNullOrBlank()) {
                ""
            } else {
                s.toString().currencyFormat()
            }
            if(this@currencyFormat is EditText){
                setSelection(text.toString().length)
            }
            addTextChangedListener(this)
        }
    })
}

fun String.currencyFormat(): String {
    var current = this
    if (current.isEmpty()) current = "0"
    return try {
        if (current.contains('.')) {
            NumberFormat.getNumberInstance(Locale.getDefault()).format(current.replace(",", "").toDouble())
        } else {
            NumberFormat.getNumberInstance(Locale.getDefault()).format(current.replace(",", "").toLong())
        }
    } catch (e: Exception) {
        "0"
    }
}

The sleep man page says it is declared in <unistd.h>.

Synopsis:

#include <unistd.h>

unsigned int sleep(unsigned int seconds);

You can use sqlcmd to run a backup, or any other T-SQL script. You can find the detailed instructions and examples on various useful sqlcmd switches in this article: Working with the SQL Server command line (sqlcmd)

Gets you pretty close, although you may need to tweak the "top" and "bottom" values.

Found another way.. I use apple's UIImage+ImageEffects.

 UIImage *effectImage = [image applyExtraLightEffect];                        
 self.imageView.image = effectImage;

maybe that will help with windows scheduled tasks ...

Dim thisMonth As New DateTime(DateTime.Today.Year, DateTime.Today.Month, 1)
Dim firstDayLastMonth As DateTime
Dim lastDayLastMonth As DateTime

firstDayLastMonth = thisMonth.AddMonths(-1)
lastDayLastMonth = thisMonth.AddDays(-1)

If you just want the extension, you can use pathinfo:

$ext = pathinfo($file_path, PATHINFO_EXTENSION);

You may use cdecl utility or its online versions, like https://cdecl.org/

For example:

void (* x)(int (*[])()); is a declare x as pointer to function (array of pointer to function returning int) returning void

You can simply add onended="myFunction()" to your video tag.

<video onended="myFunction()">
  ...
  Your browser does not support the video tag.
</video>

<script type='text/javascript'>
  function myFunction(){
    console.log("The End.")
  }
</script>

Here is how to do it programatically:

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {                
   getWindow().setNavigationBarColor(getResources().getColor(R.color.your_awesome_color));
}

Using Compat library:

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    getWindow().setNavigationBarColor(ContextCompat.getColor(this, R.color.primary));
}

Here is how to do it with xml in the values-v21/style.xml folder:

<item name="android:navigationBarColor">@color/your_color</item>

A good answer was already posted, this is only a recommendation!

A good way would be to just add a category to NSManagedObject and implement a method like I did:

Header File (e.g. NSManagedObject+Ext.h)

@interface NSManagedObject (Logic)

+ (void) deleteAllFromEntity:(NSString*) entityName;

@end

Code File: (e.g. NSManagedObject+Ext.m)

@implementation NSManagedObject (Logic)

+ (void) deleteAllFromEntity:(NSString *)entityName {
    NSManagedObjectContext *managedObjectContext = [AppDelegate managedObjectContext];
    NSFetchRequest * allRecords = [[NSFetchRequest alloc] init];
    [allRecords setEntity:[NSEntityDescription entityForName:entityName inManagedObjectContext:managedObjectContext]];
    [allRecords setIncludesPropertyValues:NO];
    NSError * error = nil;
    NSArray * result = [managedObjectContext executeFetchRequest:allRecords error:&error];
    for (NSManagedObject * profile in result) {
        [managedObjectContext deleteObject:profile];
    }
    NSError *saveError = nil;
    [managedObjectContext save:&saveError];
}

@end

... the only thing you have to is to get the managedObjectContext from the app delegate, or where every you have it in ;)

afterwards you can use it like:

[NSManagedObject deleteAllFromEntity:@"EntityName"];

one further optimization could be that you remove the parameter for tha entityname and get the name instead from the clazzname. this would lead to the usage:

[ClazzName deleteAllFromEntity];

a more clean impl (as category to NSManagedObjectContext):

@implementation NSManagedObjectContext (Logic)

- (void) deleteAllFromEntity:(NSString *)entityName {
    NSFetchRequest * allRecords = [[NSFetchRequest alloc] init];
    [allRecords setEntity:[NSEntityDescription entityForName:entityName inManagedObjectContext:self]];
    [allRecords setIncludesPropertyValues:NO];
    NSError * error = nil;
    NSArray * result = [self executeFetchRequest:allRecords error:&error];
    for (NSManagedObject * profile in result) {
        [self deleteObject:profile];
    }
    NSError *saveError = nil;
    [self save:&saveError];
}

@end

The usage then:

[managedObjectContext deleteAllFromEntity:@"EntityName"];

Based off Simon McKenzie's answer to this question, I'd suggest using a pair of methods like this:

    public static void ZipFolder(string sourceFolder, string zipFile)
    {
        if (!System.IO.Directory.Exists(sourceFolder))
            throw new ArgumentException("sourceDirectory");

        byte[] zipHeader = new byte[] { 80, 75, 5, 6, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };

        using (System.IO.FileStream fs = System.IO.File.Create(zipFile))
        {
            fs.Write(zipHeader, 0, zipHeader.Length);
        }

        dynamic shellApplication = Activator.CreateInstance(Type.GetTypeFromProgID("Shell.Application"));
        dynamic source = shellApplication.NameSpace(sourceFolder);
        dynamic destination = shellApplication.NameSpace(zipFile);

        destination.CopyHere(source.Items(), 20);
    }

    public static void UnzipFile(string zipFile, string targetFolder)
    {
        if (!System.IO.Directory.Exists(targetFolder))
            System.IO.Directory.CreateDirectory(targetFolder);

        dynamic shellApplication = Activator.CreateInstance(Type.GetTypeFromProgID("Shell.Application"));
        dynamic compressedFolderContents = shellApplication.NameSpace(zipFile).Items;
        dynamic destinationFolder = shellApplication.NameSpace(targetFolder);

        destinationFolder.CopyHere(compressedFolderContents);
    }
}

You can call bash directly within your Makefile instead of using the default shell:

bash -c "ls -al"

instead of:

ls -al
