You only need to change the access permissions for your WordPress Directory:

chown -R www-data:www-data your-wordpress-directory

XAMPP comes preloaded with the FileZilla FTP server. Here is how to setup the service, and create an account.

1. Enable the FileZilla FTP Service through the XAMPP Control Panel to make it startup automatically (check the checkbox next to filezilla to install the service). Then manually start the service.

2. Create an ftp account through the FileZilla Server Interface (its the essentially the filezilla control panel). There is a link to it Start Menu in XAMPP folder. Then go to Users->Add User->Stuff->Done.

3. Try connecting to the server (localhost, port 21).

You can use script like this for mac:

for f in $(curl -s -l -u user:pass ftp://your_ftp_server_ip/folder/) 
 do curl -O -u user:pass ftp://your_ftp_server_ip/folder/$f 
done

Window -> Show View -> Other -> Studio/Remote

(Drag this tabbed window wherever)

The existing answers are valid, but why re-invent the wheel and bother with lower level WebRequest types while WebClient already implements FTP uploading neatly:

using (var client = new WebClient())
{
    client.Credentials = new NetworkCredential(ftpUsername, ftpPassword);
    client.UploadFile("ftp://host/path.zip", WebRequestMethods.Ftp.UploadFile, localFile);
}

With google-drive-ftp-adapter I have been able to access the My Drive area of Google Drive with the FileZilla FTP client. However, I have not been able to access the Shared with me area.

You can configure which Google account credentials it uses by changing the account property in the configuration.properties file from default to the desired Google account name. See the instructions at http://www.andresoviedo.org/google-drive-ftp-adapter/

There is 'ncftp' which is available for installation in linux. This works on the FTP protocol and can be used to download files and folders recursively. works on linux. Has been used and is working fine for recursive folder/file transfer.

Check this link... http://www.ncftp.com/

You may consider FluentFTP, previously known as System.Net.FtpClient.

It is released under The MIT License and available on NuGet (FluentFTP).

The folder is part of the URL you set when you create request: "ftp://www.contoso.com/test.htm". If you use "ftp://www.contoso.com/wibble/test.htm" then the file will be uploaded to a folder named wibble.

You may need to first use a request with Method = WebRequestMethods.Ftp.MakeDirectory to make the wibble folder if it doesn't already exist.

Anonymous FTP usage is covered by RFC 1635: How to Use Anonymous FTP:

What is Anonymous FTP?

Anonymous FTP is a means by which archive sites allow general access to their archives of information. These sites create a special account called "anonymous".

…

Traditionally, this special anonymous user account accepts any string as a password, although it is common to use either the password "guest" or one's electronic mail (e-mail) address. Some archive sites now explicitly ask for the user's e-mail address and will not allow login with the "guest" password. Providing an e-mail address is a courtesy that allows archive site operators to get some idea of who is using their services.

These are general recommendations, though. Each FTP server may have its own guidelines.

For sample use of the ftp command on anonymous FTP access, see appendix A:

Currently, the link dlptest is working fine.

The files will only be stored for 30 minutes before being deleted.

There's no standard for the layout of the LIST response. You'd have to write code to handle the most popular layouts. I'd start with Linux ls and Windows Server DIR formats. There's a lot of variety out there, though.

Fall back to the nlst method (returning the result of the NLST command) if you can't parse the longer list. For bonus points, cheat: perhaps the longest number in the line containing a known file name is its length.

This script generates the command file then pipes the command file to the ftp program, creating a log along the way. Finally print the original bat file, the command files and the log of this session.

Apache commons-nets get updates more frequently recently, while Enterprise DT library seems to update even more frequently.

Ahem, because 22 is the port number for ssh and has been for ages?

In case you are getting 530 password incorrect

1 more step needed

in file /etc/shells

Add the following line

/bin/false

    ftps -a -z -e:on -pfxfile:"S-PID.p12" -pfxpwfile:"S-PID.p12.pwd" -user:<S-PID number> -s:script <RemoteServerName> 2121

S-PID.p12 => certificate file name ;
S-PID.p12.pwd => certificate password file name ; 
RemoteServerName =>  abcd123 ; 
2121 => port number ; 
ftps => command is part of ftps client software ; 

Here's what I use. In my case, certain ftp servers (pure-ftpd for one) will always prompt for the username even with the -i parameter, and catch the "user username" command as the interactive password. What I do it enter a few NOOP (no operation) commands until the ftp server times out, and then login:

open ftp.example.com 
noop
noop
noop
noop
noop
noop
noop
noop
user username password
...
quit

As other posters have pointed out, there are some limitations with the AWS Transfer for SFTP service. You need to closely align requirements. For example, there are no quotas, whitelists/blacklists, file type limits, and non key based access requires external services. There is also a certain overhead relating to user management and IAM, which can get to be a pain at scale.

We have been running an SFTP S3 Proxy Gateway for about 5 years now for our customers. The core solution is wrapped in a collection of Docker services and deployed in whatever context is needed, even on-premise or local development servers. The use case for us is a little different as our solution is focused data processing and pipelines vs a file share. In a Salesforce example, a customer will use SFTP as the transport method sending email, purchase...data to an SFTP/S3 enpoint. This is mapped an object key on S3. Upon arrival, the data is picked up, processed, routed and loaded to a warehouse. We also have fairly significant auditing requirements for each transfer, something the Cloudwatch logs for AWS do not directly provide.

As other have mentioned, rolling your own is an option too. Using AWS Lightsail you can setup a cluster, say 4, of $10 2GB instances using either Route 53 or an ELB.

In general, it is great to see AWS offer this service and I expect it to mature over time. However, depending on your use case, alternative solutions may be a better fit.

Active and passive are the two modes that FTP can run in.

For background, FTP actually uses two channels between client and server, the command and data channels, which are actually separate TCP connections.

The command channel is for commands and responses while the data channel is for actually transferring files.

This separation of command information and data into separate channels a nifty way of being able to send commands to the server without having to wait for the current data transfer to finish. As per the RFC, this is only mandated for a subset of commands, such as quitting, aborting the current transfer, and getting the status.

In active mode, the client establishes the command channel but the server is responsible for establishing the data channel. This can actually be a problem if, for example, the client machine is protected by firewalls and will not allow unauthorised session requests from external parties.

In passive mode, the client establishes both channels. We already know it establishes the command channel in active mode and it does the same here.

However, it then requests the server (on the command channel) to start listening on a port (at the servers discretion) rather than trying to establish a connection back to the client.

As part of this, the server also returns to the client the port number it has selected to listen on, so that the client knows how to connect to it.

Once the client knows that, it can then successfully create the data channel and continue.

More details are available in the RFC: https://www.ietf.org/rfc/rfc959.txt

Try using the wget library for python. You can find the documentation for it here.

import wget
link = 'ftp://example.com/foo.txt'
wget.download(link)

Mysqli isn't installed on the new server. Run phpinfo() to confirm.

<?php 

phpinfo();

You can use a heredoc to do this e.g.

ftp -n $Server <<End-Of-Session
# -n option disables auto-logon

user anonymous "$Password"
binary
cd $Directory
put "$Filename.lsm"
put "$Filename.tar.gz"
bye
End-Of-Session

so the ftp process is fed on stdin with everything up to End-Of-Session. A useful tip for spawning any process, not just ftp! Note that this saves spawning a separate process (echo, cat etc.). Not a major resource saving, but worth bearing in mind.

The AlexFTPS library used in the question seems to be dead (was not updated since 2011).

With no external libraries

You can try to implement this without any external library. But unfortunately, neither the .NET Framework nor PowerShell have any explicit support for downloading all files in a directory (let only recursive file downloads).

You have to implement that yourself:

• List the remote directory
• Iterate the entries, downloading files (and optionally recursing into subdirectories - listing them again, etc.)

Tricky part is to identify files from subdirectories. There's no way to do that in a portable way with the .NET framework (FtpWebRequest or WebClient). The .NET framework unfortunately does not support the MLSD command, which is the only portable way to retrieve directory listing with file attributes in FTP protocol. See also Checking if object on FTP server is file or directory.

Your options are:

• If you know that the directory does not contain any subdirectories, use the ListDirectory method (NLST FTP command) and simply download all the "names" as files.
• Do an operation on a file name that is certain to fail for file and succeeds for directories (or vice versa). I.e. you can try to download the "name".
• You may be lucky and in your specific case, you can tell a file from a directory by a file name (i.e. all your files have an extension, while subdirectories do not)
• You use a long directory listing (LIST command = ListDirectoryDetails method) and try to parse a server-specific listing. Many FTP servers use *nix-style listing, where you identify a directory by the d at the very beginning of the entry. But many servers use a different format. The following example uses this approach (assuming the *nix format)

function DownloadFtpDirectory($url, $credentials, $localPath)
{
    $listRequest = [Net.WebRequest]::Create($url)
    $listRequest.Method = [System.Net.WebRequestMethods+Ftp]::ListDirectoryDetails
    $listRequest.Credentials = $credentials

    $lines = New-Object System.Collections.ArrayList

    $listResponse = $listRequest.GetResponse()
    $listStream = $listResponse.GetResponseStream()
    $listReader = New-Object System.IO.StreamReader($listStream)
    while (!$listReader.EndOfStream)
    {
        $line = $listReader.ReadLine()
        $lines.Add($line) | Out-Null
    }
    $listReader.Dispose()
    $listStream.Dispose()
    $listResponse.Dispose()

    foreach ($line in $lines)
    {
        $tokens = $line.Split(" ", 9, [StringSplitOptions]::RemoveEmptyEntries)
        $name = $tokens[8]
        $permissions = $tokens[0]

        $localFilePath = Join-Path $localPath $name
        $fileUrl = ($url + $name)

        if ($permissions[0] -eq 'd')
        {
            if (!(Test-Path $localFilePath -PathType container))
            {
                Write-Host "Creating directory $localFilePath"
                New-Item $localFilePath -Type directory | Out-Null
            }

            DownloadFtpDirectory ($fileUrl + "/") $credentials $localFilePath
        }
        else
        {
            Write-Host "Downloading $fileUrl to $localFilePath"

            $downloadRequest = [Net.WebRequest]::Create($fileUrl)
            $downloadRequest.Method = [System.Net.WebRequestMethods+Ftp]::DownloadFile
            $downloadRequest.Credentials = $credentials

            $downloadResponse = $downloadRequest.GetResponse()
            $sourceStream = $downloadResponse.GetResponseStream()
            $targetStream = [System.IO.File]::Create($localFilePath)
            $buffer = New-Object byte[] 10240
            while (($read = $sourceStream.Read($buffer, 0, $buffer.Length)) -gt 0)
            {
                $targetStream.Write($buffer, 0, $read);
            }
            $targetStream.Dispose()
            $sourceStream.Dispose()
            $downloadResponse.Dispose()
        }
    }
}

Use the function like:

$credentials = New-Object System.Net.NetworkCredential("user", "mypassword") 
$url = "ftp://ftp.example.com/directory/to/download/"
DownloadFtpDirectory $url $credentials "C:\target\directory"

The code is translated from my C# example in C# Download all files and subdirectories through FTP.

Using 3rd party library

If you want to avoid troubles with parsing the server-specific directory listing formats, use a 3rd party library that supports the MLSD command and/or parsing various LIST listing formats. And ideally with a support for downloading all files from a directory or even recursive downloads.

For example with WinSCP .NET assembly you can download whole directory with a single call to Session.GetFiles:

# Load WinSCP .NET assembly
Add-Type -Path "WinSCPnet.dll"

# Setup session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Ftp
    HostName = "ftp.example.com"
    UserName = "user"
    Password = "mypassword"
}

$session = New-Object WinSCP.Session

try
{
    # Connect
    $session.Open($sessionOptions)

    # Download files
    $session.GetFiles("/directory/to/download/*", "C:\target\directory\*").Check()
}
finally
{
    # Disconnect, clean up
    $session.Dispose()
}    

Internally, WinSCP uses the MLSD command, if supported by the server. If not, it uses the LIST command and supports dozens of different listing formats.

The Session.GetFiles method is recursive by default.

Most of the answers here involves configuring, actually just by adding sftp:// on your host (see below image) you can instantly fixed that kind of problem, works for me.

And also take note that if you follow Vaggelis guide you are lowering your security, sftp is better than using plain ftp.

I just changed the encryption from "Use explicit FTP over TLS if available" to "Only use plain FTP" (insecure) at site manager and it works!

If you are using Windows 10, install Windows Subsystem for Linux, WSL and Ubuntu.

For pyftpdlib users. I found this on the pyftpdlib website. This creates anonymous ftp with write access to your filesystem so please use with due care. More features are available under the hood for better security so just go look:

sudo pip3 install pyftpdlib

python3 -m pyftpdlib -w  

## updated for python3 Feb14:2020

Might be helpful for those that tried using the deprecated method above.

sudo python -m pyftpdlib.ftpserver

"Whenever you use the WordPress control panel to automatically install, upgrade, or delete plugins, WordPress must make changes to files on the filesystem.

Before making any changes, WordPress first checks to see whether or not it has access to directly manipulate the file system.

If WordPress does not have the necessary permissions to modify the filesystem directly, you will be asked for FTP credentials so that WordPress can try to do what it needs to via FTP."

Solution: In order to find out what user your instance of apache is running as, create a test script with the following content:

<?php echo(exec("whoami")); ?>

For me, it was daemon and not www-data. Then, fix the permission by:

sudo chown -R daemon /path/to/your/local/www/folder

    private static DataTable ReadFTP_CSV()
    {
        String ftpserver = "ftp://servername/ImportData/xxxx.csv";
        FtpWebRequest reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(ftpserver));

        reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
        FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();

        Stream responseStream = response.GetResponseStream();

        // use the stream to read file from FTP 
        StreamReader sr = new StreamReader(responseStream);
        DataTable dt_csvFile = new DataTable();

        #region Code
        //Add Code Here To Loop txt or CSV file
        #endregion

        return dt_csvFile;

    }

I hope it can help you.

Assume LMN2011* files are inside /home/me but skipping anything in /home/me/temp or below:

find /home/me -name 'LMN2011*' -not -path "/home/me/temp/*" -print | xargs grep 'LMN20113456'

I just benchmarked a file transfer over both FTP and HTTP :

• over two very good server connections
• using the same 1GB .zip file
• under the same network conditions (tested one after the other)

The result:

• using FTP: 6 minutes
• using HTTP: 4 minutes
• using a concurrent http downloader software (fdm): 1 minute

So, basically under a "real life" situation:

1) HTTP is faster than FTP when downloading one big file.

2) HTTP can use parallel chunk download which makes it 6x times faster than FTP depending on the network conditions.

Yes, encryption add some load to your cpu, but if your cpu is not ancient that should not affect as much as you say.

If you enable compression for SSH, SCP is actually faster than FTP despite the SSH encryption (if I remember, twice as fast as FTP for the files I tried). I haven't actually used SFTP, but I believe it uses SCP for the actual file transfer. So please try this and let us know :-)

I just answered a similar question here IMHO, if your FTP server is able to communicate with Fabric please us Fabric. It is far better than doing raw ftp.

I have an FTP account from dotgeek.com so I am not sure if this will work for other FTP accounts.

#!/usr/bin/python

from fabric.api import run, env, sudo, put

env.user = 'username'
env.hosts = ['ftp_host_name',]     # such as ftp.google.com

def copy():
    # assuming i have wong_8066.zip in the same directory as this script
    put('wong_8066.zip', '/www/public/wong_8066.zip')

save the file as fabfile.py and run fab copy locally.

yeukhon@yeukhon-P5E-VM-DO:~$ fab copy2
[1.ai] Executing task 'copy2'
[1.ai] Login password: 
[1.ai] put: wong_8066.zip -> /www/public/wong_8066.zip

Done.
Disconnecting from 1.ai... done.

Once again, if you don't want to input password all the time, just add

env.password = 'my_password'

have you checked RSE (Remote System Explorer) ? I think it's pretty close to what you want to achieve.

a blog post about it, with screenshots

As an alternative, if you don't want to create config files, do the unattended upload with curl instead of ftp:

curl -u user:password -T file ftp://server/dir/file

This was the solution I came up with http://sourceforge.net/projects/sshtools/ (most error handling omitted for clarity). This is an excerpt from my blog

SshClient ssh = new SshClient();
ssh.connect(host, port);
//Authenticate
PasswordAuthenticationClient passwordAuthenticationClient = new PasswordAuthenticationClient();
passwordAuthenticationClient.setUsername(userName);
passwordAuthenticationClient.setPassword(password);
int result = ssh.authenticate(passwordAuthenticationClient);
if(result != AuthenticationProtocolState.COMPLETE){
     throw new SFTPException("Login to " + host + ":" + port + " " + userName + "/" + password + " failed");
}
//Open the SFTP channel
SftpClient client = ssh.openSftpClient();
//Send the file
client.put(filePath);
//disconnect
client.quit();
ssh.disconnect();

You are using the FTP in an active mode.

Setting up the FTP in the active mode can be cumbersome nowadays due to firewalls and NATs.

It's likely because of your local firewall or NAT that the server was not able to connect back to your client to establish data transfer connection.

Or your client is not aware of its external IP address and provides an internal address instead to the server (in PORT command), which the server is obviously not able to use. But it should not be the case, as vsftpd by default rejects data transfer address not identical to source address of FTP control connection (the port_promiscuous directive).

See my article Network Configuration for Active Mode.

If possible, you should use a passive mode as it typically requires no additional setup on a client-side. That's also what the server suggested you by "Consider using PASV". The PASV is an FTP command used to enter the passive mode.

Unfortunately Windows FTP command-line client (the ftp.exe) does not support passive mode at all. It makes it pretty useless nowadays.

Use any other 3rd party Windows FTP command-line client instead. Most other support the passive mode.

For example WinSCP FTP client defaults to the passive mode and there's a guide available for converting Windows FTP script to WinSCP script.

(I'm the author of WinSCP)

Goyuix's solution works great, but as presented it gives me this error: "The requested FTP command is not supported when using HTTP proxy."

Adding this line after $ftp.UsePassive = $true fixed the problem for me:

$ftp.Proxy = $null;

import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;

String FilePath = "/home/lahiru/Desktop/Sample.xls";
FileInputStream fs = new FileInputStream(FilePath);
Workbook wb = Workbook.getWorkbook(fs);

String <variable> = sh.getCell("A2").getContents();

Turns out, when the table name is different than the model name, you have to change the annotations to:

@Entity
@Table(name = "table_name")
class WhateverNameYouWant {
    ...

Instead of simply using the @Entity annotation.

What was weird for me, is that the class it was trying to convert to didn't exist. This worked for me.

You are getting that error because when the param1 if statements are evaluated, param is always null due to being scoped variables without delayed expansion.

When parentheses are used, all the commands and variables within those parentheses are expanded. And at that time, param1 has no value making the if statements invalid. When using delayed expansion, the variables are only expanded when the command is actually called.

Also I recommend using if not defined command to determine if a variable is set.

From this documentation

pandas provides a single function, merge, as the entry point for all standard database join operations between DataFrame objects:

merge(left, right, how='inner', on=None, left_on=None, right_on=None,
      left_index=False, right_index=False, sort=True,
      suffixes=('_x', '_y'), copy=True, indicator=False)

And :

DataFrame.join is a convenient method for combining the columns of two potentially differently-indexed DataFrames into a single result DataFrame. Here is a very basic example: The data alignment here is on the indexes (row labels). This same behavior can be achieved using merge plus additional arguments instructing it to use the indexes:

result = pd.merge(left, right, left_index=True, right_index=True,
how='outer')

Depends on the database system.

Generally with no special characters, yes, = and LIKE are the same.

Some database systems, however, may treat collation settings differently with the different operators.

For instance, in MySQL comparisons with = on strings is always case-insensitive by default, so LIKE without special characters is the same. On some other RDBMS's LIKE is case-insensitive while = is not.

Visual Studio's search in folders is by far the fastest I've found.

I believe it intelligently searches only text (non-binary) files, and subsequent searches in the same folder are extremely fast, unlike with the other tools (likely the text files fit in the windows disk cache).

VS2010 on a regular hard drive, no SSD, takes 1 minute to search a 20GB folder with 26k files, source code and binaries mixed up. 15k files are searched - the rest are likely skipped due to being binary files. Subsequent searches in the same folder are on the order of seconds (until stuff gets evicted form the cache).

The next closest I've found for the same folder was grepWin. Around 3 minutes. I excluded files larger than 2000KB (default). The "Include binary files" setting seems to do nothing in terms of speeding up the search, it looks like binary files are still touched (bug?), but they don't show up in the search results. Subsequent searches all take the same 3 minutes - can't take advantage of hard drive cache. If I restrict to files smaller than 200k, the initial search is 2.5min and subsequent searches are on the order of seconds, about as fast as VS - in the cache.

Agent Ransack and FileSeek are both very slow on that folder, around 20min, due to searching through everything, including giant multi-gigabyte binary files. They search at about 10-20MB per second according to Resource Monitor.

UPDATE: Agent Ransack can be set to search files of certain sizes, and using the <200KB cutoff it's 1:15min for a fresh search and 5s for subsequent searches. Faster than grepWin and as fast as VS overall. It's actually pretty nice if you want to keep several searches in tabs and you don't want to pollute the VS recently searched folders list, and you want to keep the ability to search binaries, which VS doesn't seem to wanna do. Agent Ransack also creates an explorer context menu entry, so it's easy to launch from a folder. Same as grepWin but nicer UI and faster.

My new search setup is Agent Ransack for contents and Everything for file names (awesome tool, instant results!).

If anyone needs the registry entries for Windows 7 64-bit, here they are. What was good for me as to remove the overlays for items not really used often: Drop Box, Google Drive, Microsoft Products, and just kept the overlays for Tortoise. These are all the overlays - nothing is removed.

** Caution ** Playing with the registry can make your system unstable. Be sure to backup your registry. See this Google search on various ways to backup your registry or registry setting(s).

Remember, these are for Windows 64-bit and you should take a backup of your registry be

public ActionResult Index(int id,string value)

This function get values form URL After that you can use below function

Request.RawUrl - Return complete URL of Current page

RouteData.Values - Return Collection of Values of URL

Request.Params - Return Name Value Collections

ok, here is my final solution with 100% native javascript:

<meta id="viewport" name="viewport">

<script type="text/javascript">
//mobile viewport hack
(function(){

  function apply_viewport(){
    if( /Android|webOS|iPhone|iPad|iPod|BlackBerry/i.test(navigator.userAgent)   ) {

      var ww = window.screen.width;
      var mw = 800; // min width of site
      var ratio =  ww / mw; //calculate ratio
      var viewport_meta_tag = document.getElementById('viewport');
      if( ww < mw){ //smaller than minimum size
        viewport_meta_tag.setAttribute('content', 'initial-scale=' + ratio + ', maximum-scale=' + ratio + ', minimum-scale=' + ratio + ', user-scalable=no, width=' + mw);
      }
      else { //regular size
        viewport_meta_tag.setAttribute('content', 'initial-scale=1.0, maximum-scale=1, minimum-scale=1.0, user-scalable=yes, width=' + ww);
      }
    }
  }

  //ok, i need to update viewport scale if screen dimentions changed
  window.addEventListener('resize', function(){
    apply_viewport();
  });

  apply_viewport();

}());
</script>

The advice these days is:

Optimize for 1024x768. For most sites this will cover most visitors. Most logs show that 92-99% of your visits will be over 1024 wide. While 1280 is increasingly common, there are still lots at 1024 and some below that. Optimize for this but don't ignore the others.

1024 = ~960. Accounting for scrollbars, window edges, etc means the real width of a 1024x768 screen is about 960 pixels. Some tools are based on a slightly smaller size, about 940. This is the default container width in twitter bootstrap.

Don't design for one size. Window sizes vary. Don't assume screen size equals windows size. Design for a reasonable minimum, but assume it will adjust.

Use responsive design and liquid layouts. Use layouts that will adjust when the window is resized. People do this a lot, especially on big monitors. This is just good CSS practice. There are several front-end frameworks that support this.

Treat mobile as a first-class citizen. You are getting more traffic from mobile devices all the time. These introduce even more screen sizes. You can still optimize for 960, but using responsive web design techniques means your page will adjust based on the screen size.

Log browser display info. You can get actual numbers about this. I found some numbers here and here and here. You can also rig your site to collect the same data.

User will scroll so don't worry much about height. The old argument was that users wouldn't scroll and anything important should be "above the fold." This was overturned years ago. Users scroll a lot.

You can put the data in a file and re-direct it like this:

$ cat file.sh
#!/bin/bash

read x

echo $x
echo $y

In C++ language the result of the subexpresison is never affected by the surrounding context (with some rare exceptions). This is one of the principles that the language carefully follows. The expression c = a / b contains of an independent subexpression a / b, which is interpreted independently from anything outside that subexpression. The language does not care that you later will assign the result to a double. a / b is an integer division. Anything else does not matter. You will see this principle followed in many corners of the language specification. That's juts how C++ (and C) works.

One example of an exception I mentioned above is the function pointer assignment/initialization in situations with function overloading

void foo(int);
void foo(double);

void (*p)(double) = &foo; // automatically selects `foo(fouble)`

This is one context where the left-hand side of an assignment/initialization affects the behavior of the right-hand side. (Also, reference-to-array initialization prevents array type decay, which is another example of similar behavior.) In all other cases the right-hand side completely ignores the left-hand side.

According to the javadoc a Scanner does not seem to be intended for reading single characters. You attach a Scanner to an InputStream (or something else) and it parses the input for you. It also can strip of unwanted characters. So you can read numbers, lines, etc. easily. When you need only the characters from your input, use a InputStreamReader for example.

Try doing this if you're running Visual Studio Code on a Windows machine and getting this error (I'm using Windows 10).

Go to the settings and change the Python path to the location of YOUR python installation.

I.e.,

Change: "python.pythonPath": "python"

To: "python.pythonPath": "C:\\Python36\\python.exe"

And then: Save and reload Visual Studio Code.

Now when you get the prompt telling you that "Linter pylint is not installed", just select the option to 'install pylint'.

Since you've now provided the correct path to your Python installation, the Pylint installation will be successfully completed in the Windows PowerShell Terminal.

I remember JavaScript Closures when I See this.. Here is how i do it..

        function Increment() {
            var num = 0; // Here num is a private static variable
            return function () {
                return ++num;
            }
        }

        var inc = new Increment();
        console.log(inc());//Prints 1
        console.log(inc());//Prints 2
        console.log(inc());//Prints 3

Try this:

for(String str: myList) {
    if(str.trim().equals("A"))
       return true;
}
return false;

You need to use str.equals or str.equalsIgnoreCase instead of contains because contains in string works not the same as contains in List

List<String> s = Arrays.asList("BAB", "SAB", "DAS");
s.contains("A"); // false
"BAB".contains("A"); // true

[x for x in L if 'ab' in x]

The trick here is to use the -C (comment) parameter to specify your GCE userid. It looks like Google introduced this change last in 2018.

If the Google user who owns the GCE instance is [email protected] (which you will use as your login userid), then generate the key pair with (for example)

ssh-keygen -b521 -t ecdsa -C myname -f mykeypair

When you paste mykeypair.pub into the instance's public key list, you should see "myname" appear as the userid of the key.

Setting this up will let you use ssh, scp, etc from your command line.

The Typedef is a Keyword in C and C++. It is used to create new names for basic data types (char, int, float, double, struct & enum).

typedef enum {
    kCircle,
    kRectangle,
    kOblateSpheroid
} ShapeType;

Here it creates enumerated data type ShapeType & we can write new names for enum type ShapeType as given below

ShapeType shape1; 
ShapeType shape2; 
ShapeType shape3;

myString += Environment.NewLine;

myString = myString + Environment.NewLine;

$solution = $query->distinct()

                ]
            )
            ->get();

Remember the group by is optional,this should work in most cases when you want a count group by to exclude duplicated select values, the addSelect is a querybuilder instance method.

In Ubuntu 16.04 (MySQL version 5.7.13) I was able to resolve the problem with the steps below:

1. Follow the instructions from the in section B.5.3.2.2 Resetting the Root Password: Unix and Unix-Like Systems MySQL 5.7 reference manual

2. When I tried #sudo mysqld_safe --init-file=/home/me/mysql-init & it failed. The error was in /var/log/mysql/error.log

   2016-08-10T11:41:20.421946Z 0 [Note] Execution of init_file '/home/me/mysql/mysql-init' started. 2016-08-10T11:41:20.422070Z 0 [ERROR] /usr/sbin/mysqld: File '/home/me/mysql/mysql-init' not found (Errcode: 13 - Permission denied) 2016-08-10T11:41:20.422096Z 0 [ERROR] Aborting

The file permission of mysql-init was not the problem, need to edit apparmor permission

3. Edit by #sudo vi /etc/apparmor.d/usr.sbin.mysqld

   ....
     /var/log/mysql/ r,
     /var/log/mysql/** rw,
   
   
   # Allow user init file
     /home/pranab/mysql/* r,
   
     # Site-specific additions and overrides. See local/README for details.
     #include <local/usr.sbin.mysqld>
   }
   

4. Do #sudo /etc/init.d/apparmor reload

5. Start mysqld_safe again try step 2 above. Check /var/log/mysql/error.log make sure there is no error and the mysqld is successfully started

6. Run #mysql -u root -p

   Enter password:

Enter the password that you specified in mysql-init. You should be able to log in as root now.

7. Shutdown mysqld_safe by #sudo mysqladmin -u root -p shutdown

8. Start mysqld normal way by #sudo systemctl start mysql

You can use JSON.stringify(object) with an object and I just wrote a function that'll recursively convert an array to an object, like this JSON.stringify(convArrToObj(array)), which is the following code (more detail can be found on this answer):

// Convert array to object
var convArrToObj = function(array){
    var thisEleObj = new Object();
    if(typeof array == "object"){
        for(var i in array){
            var thisEle = convArrToObj(array[i]);
            thisEleObj[i] = thisEle;
        }
    }else {
        thisEleObj = array;
    }
    return thisEleObj;
}

To make it more generic, you can override the JSON.stringify function and you won't have to worry about it again, to do this, just paste this at the top of your page:

// Modify JSON.stringify to allow recursive and single-level arrays
(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        return oldJSONStringify(convArrToObj(input));
    };
})();

And now JSON.stringify will accept arrays or objects! (link to jsFiddle with example)

Edit:

Here's another version that's a tad bit more efficient, although it may or may not be less reliable (not sure -- it depends on if JSON.stringify(array) always returns [], which I don't see much reason why it wouldn't, so this function should be better as it does a little less work when you use JSON.stringify with an object):

(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        if(oldJSONStringify(input) == '[]')
            return oldJSONStringify(convArrToObj(input));
        else
            return oldJSONStringify(input);
    };
})();

Here is the raw way to do it

$startTimeStamp = strtotime("2011/07/01");
$endTimeStamp = strtotime("2011/07/17");

$timeDiff = abs($endTimeStamp - $startTimeStamp);

$numberDays = $timeDiff/86400;  // 86400 seconds in one day

// and you might want to convert to integer
$numberDays = intval($numberDays);

You may want to use setArray method as mentioned in the javadoc below:

http://docs.oracle.com/javase/6/docs/api/java/sql/PreparedStatement.html#setArray(int, java.sql.Array)

Sample Code:

PreparedStatement pstmt = 
                conn.prepareStatement("select * from employee where id in (?)");
Array array = conn.createArrayOf("VARCHAR", new Object[]{"1", "2","3"});

A POCO follows the rules of OOP. It should (but doesn't have to) have state and behavior. POCO comes from POJO, coined by Martin Fowler [anecdote here]. He used the term POJO as a way to make it more sexy to reject the framework heavy EJB implementations. POCO should be used in the same context in .Net. Don't let frameworks dictate your object's design.

A DTO's only purpose is to transfer state, and should have no behavior. See Martin Fowler's explanation of a DTO for an example of the use of this pattern.

Here's the difference: POCO describes an approach to programming (good old fashioned object oriented programming), where DTO is a pattern that is used to "transfer data" using objects.

While you can treat POCOs like DTOs, you run the risk of creating an anemic domain model if you do so. Additionally, there's a mismatch in structure, since DTOs should be designed to transfer data, not to represent the true structure of the business domain. The result of this is that DTOs tend to be more flat than your actual domain.

In a domain of any reasonable complexity, you're almost always better off creating separate domain POCOs and translating them to DTOs. DDD (domain driven design) defines the anti-corruption layer (another link here, but best thing to do is buy the book), which is a good structure that makes the segregation clear.

An alternative for the bind() method.

Use the click() method, do something like this:

commentbtn.click({id: 10, name: "João"}, onClickCommentBtn);

function onClickCommentBtn(event)
{
  alert("Id=" + event.data.id + ", Name = " + event.data.name);
}

Or, if you prefer:

commentbtn.click({id: 10, name: "João"},  function (event) {
  alert("Id=" + event.data.id + ", Nome = " + event.data.name);
});

It will show an alert box with the following infos:

Id = 10, Name = João

Yup, use printf("hello%%"); and it's done.

There is the wget command or the curl.

You can now use the file you downloaded with wget. Or you can handle a stream with curl.

This solution without timeouts! Real force redraw! For Android and iOS.

var forceRedraw = function(element){
  var disp = element.style.display;
  element.style.display = 'none';
  var trick = element.offsetHeight;
  element.style.display = disp;
};

Since you accepted an answer in which a list was not used, I'll assume the answer to my comment question is "No, it doesn't have to be a list". I also had the impression that maybe you were rending the HTML server side, since "checked" is present in your sample HTML (this would not be needed if ng-model were used to model your checkboxes).

Anyway, here's what I had in mind when I asked the question, also assuming you were generating the HTML server-side:

<div ng-controller="MyCtrl" 
 ng-init="checkboxes = {apple: true, orange: false, pear: true, naartjie: false}">
    <input type="checkbox" ng-model="checkboxes.apple">apple
    <input type="checkbox" ng-model="checkboxes.orange">orange
    <input type="checkbox" ng-model="checkboxes.pear">pear
    <input type="checkbox" ng-model="checkboxes.naartjie">naartjie
    <br>{{checkboxes}}
</div>

ng-init allows server-side generated HTML to initially set certain checkboxes.

Fiddle.

Compiled query will increase performance of your application, but it has nothing in common with ASP.NET MVC. It will speed up every db application, so it is not really about MVC.

If you're using IntelliJ 13 with SVN 1.8, you have to install SVN command line client. Please see more information here:

Unlike its earlier versions, Subversion 1.8 support uses the native command line client instead of SVNKit to run commands. This approach is more flexible and makes the support of upcoming versions much easier. Now, IntelliJ IDEA offers different integration options for each specific Subversion:

1.6 – SVNKit only

1.7 – SVNKit and command line client

1.8 – Command line client only

I solved the same problem following this example:

This example uses the jQuery JavaScript library.

First, create an Ajax icon using the AjaxLoad site.
Then add the following to your HTML :

<img src="/images/loading.gif" id="loading-indicator" style="display:none" />

And the following to your CSS file:

#loading-indicator {
  position: absolute;
  left: 10px;
  top: 10px;
}

Lastly, you need to hook into the Ajax events that jQuery provides; one event handler for when the Ajax request begins, and one for when it ends:

$(document).ajaxSend(function(event, request, settings) {
    $('#loading-indicator').show();
});

$(document).ajaxComplete(function(event, request, settings) {
    $('#loading-indicator').hide();
});

This solution is from the following link. How to display an animated icon during Ajax request processing

you can do this with object spreading code :

 this.setState((state)=>({ someProperty:{...state.someProperty,flag:false}})

this will work for more nested property

On the command prompt, do:

netstat -nb

Sure.. Why not?
Abstract base classes are just a convenience to house behavior and data common to 2 or more classes in a single place for efficiency of storage and maintenance. Its an implementation detail.
Take care however that you are not using an abstract base class where you should be using an interface. Refer to Interface vs Base class

OCR which stands for Optical Character Recognition is a computer vision technique used to identify the different types of handwritten digits that are used in common mathematics. To perform OCR in OpenCV we will use the KNN algorithm which detects the nearest k neighbors of a particular data point and then classifies that data point based on the class type detected for n neighbors.

Data Used

This data contains 5000 handwritten digits where there are 500 digits for every type of digit. Each digit is of 20×20 pixel dimensions. We will split the data such that 250 digits are for training and 250 digits are for testing for every class.

Below is the implementation.

Output

91.64

Well, I decided to workout myself on my question to solve the above problem. What I wanted is to implement a simple OCR using KNearest or SVM features in OpenCV. And below is what I did and how. (it is just for learning how to use KNearest for simple OCR purposes).

1) My first question was about letter_recognition.data file that comes with OpenCV samples. I wanted to know what is inside that file.

It contains a letter, along with 16 features of that letter.

And this SOF helped me to find it. These 16 features are explained in the paper Letter Recognition Using Holland-Style Adaptive Classifiers. (Although I didn't understand some of the features at the end)

2) Since I knew, without understanding all those features, it is difficult to do that method. I tried some other papers, but all were a little difficult for a beginner.

So I just decided to take all the pixel values as my features. (I was not worried about accuracy or performance, I just wanted it to work, at least with the least accuracy)

I took the below image for my training data:

(I know the amount of training data is less. But, since all letters are of the same font and size, I decided to try on this).

To prepare the data for training, I made a small code in OpenCV. It does the following things:

1. It loads the image.
2. Selects the digits (obviously by contour finding and applying constraints on area and height of letters to avoid false detections).
3. Draws the bounding rectangle around one letter and wait for key press manually. This time we press the digit key ourselves corresponding to the letter in the box.
4. Once the corresponding digit key is pressed, it resizes this box to 10x10 and saves all 100 pixel values in an array (here, samples) and corresponding manually entered digit in another array(here, responses).
5. Then save both the arrays in separate .txt files.

At the end of the manual classification of digits, all the digits in the training data (train.png) are labeled manually by ourselves, image will look like below:

Below is the code I used for the above purpose (of course, not so clean):

import sys

import numpy as np
import cv2

im = cv2.imread('pitrain.png')
im3 = im.copy()

gray = cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
blur = cv2.GaussianBlur(gray,(5,5),0)
thresh = cv2.adaptiveThreshold(blur,255,1,1,11,2)

#################      Now finding Contours         ###################

contours,hierarchy = cv2.findContours(thresh,cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE)

samples =  np.empty((0,100))
responses = []
keys = [i for i in range(48,58)]

for cnt in contours:
    if cv2.contourArea(cnt)>50:
        [x,y,w,h] = cv2.boundingRect(cnt)
        
        if  h>28:
            cv2.rectangle(im,(x,y),(x+w,y+h),(0,0,255),2)
            roi = thresh[y:y+h,x:x+w]
            roismall = cv2.resize(roi,(10,10))
            cv2.imshow('norm',im)
            key = cv2.waitKey(0)

            if key == 27:  # (escape to quit)
                sys.exit()
            elif key in keys:
                responses.append(int(chr(key)))
                sample = roismall.reshape((1,100))
                samples = np.append(samples,sample,0)

responses = np.array(responses,np.float32)
responses = responses.reshape((responses.size,1))
print "training complete"

np.savetxt('generalsamples.data',samples)
np.savetxt('generalresponses.data',responses)

Now we enter in to training and testing part.

For the testing part, I used the below image, which has the same type of letters I used for the training phase.

For training we do as follows:

1. Load the .txt files we already saved earlier
2. create an instance of the classifier we are using (it is KNearest in this case)
3. Then we use KNearest.train function to train the data

For testing purposes, we do as follows:

1. We load the image used for testing
2. process the image as earlier and extract each digit using contour methods
3. Draw a bounding box for it, then resize it to 10x10, and store its pixel values in an array as done earlier.
4. Then we use KNearest.find_nearest() function to find the nearest item to the one we gave. ( If lucky, it recognizes the correct digit.)

I included last two steps (training and testing) in single code below:

import cv2
import numpy as np

#######   training part    ############### 
samples = np.loadtxt('generalsamples.data',np.float32)
responses = np.loadtxt('generalresponses.data',np.float32)
responses = responses.reshape((responses.size,1))

model = cv2.KNearest()
model.train(samples,responses)

############################# testing part  #########################

im = cv2.imread('pi.png')
out = np.zeros(im.shape,np.uint8)
gray = cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
thresh = cv2.adaptiveThreshold(gray,255,1,1,11,2)

contours,hierarchy = cv2.findContours(thresh,cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE)

for cnt in contours:
    if cv2.contourArea(cnt)>50:
        [x,y,w,h] = cv2.boundingRect(cnt)
        if  h>28:
            cv2.rectangle(im,(x,y),(x+w,y+h),(0,255,0),2)
            roi = thresh[y:y+h,x:x+w]
            roismall = cv2.resize(roi,(10,10))
            roismall = roismall.reshape((1,100))
            roismall = np.float32(roismall)
            retval, results, neigh_resp, dists = model.find_nearest(roismall, k = 1)
            string = str(int((results[0][0])))
            cv2.putText(out,string,(x,y+h),0,1,(0,255,0))

cv2.imshow('im',im)
cv2.imshow('out',out)
cv2.waitKey(0)

And it worked, below is the result I got:

Here it worked with 100% accuracy. I assume this is because all the digits are of the same kind and the same size.

But anyway, this is a good start to go for beginners (I hope so).

char *arr; above statement implies that arr is a character pointer and it can point to either one character or strings of character

& char arr[]; above statement implies that arr is strings of character and can store as many characters as possible or even one but will always count on '\0' character hence making it a string ( e.g. char arr[]= "a" is similar to char arr[]={'a','\0'} )

But when used as parameters in called function, the string passed is stored character by character in formal arguments making no difference.

You want the NPGSQL library. Your only other alternative is ODBC.

So the query I was assigned to optimize was written with two CTEs in SQL server. It was taking 28sec.

I spent two minutes converting them to temp tables and the query took 3 seconds

I added an index to the temp table on the field it was being joined on and got it down to 2 seconds

Three minutes of work and now its running 12x faster all by removing CTE. I personally will not use CTEs ever they are tougher to debug as well.

The crazy thing is the CTEs were both only used once and still putting an index on them proved to be 50% faster.

You must set Access-Control-Allow-Credentials: true, if you want to use "cookie" via "Credentials"

app.all('*', function(req, res, next) {
  res.header('Access-Control-Allow-Origin', '*');
  res.header('Access-Control-Allow-Credentials', true);
  res.header('Access-Control-Allow-Methods', 'PUT, GET, POST, DELETE, OPTIONS');
  res.header('Access-Control-Allow-Headers', 'Content-Type');
  next();
});

If git rebase --abort doesnt work and you still get

error: could not read '.git/rebase-apply/head-name': No such file or directory

Type:

git rebase --quit

I would try putting a

Log.e("SOMETAG", "dialog button was clicked");

before the dialog.dismiss() line in your code to see if it actually reaches that section.

MacOS: composer is available on brew now (Tested on Php7+):

brew install composer

Install instructions on the Composer Docs page are quite to the point otherwise.

Note also that table names are case sensitive on Linux unless you set the lower_case_table_name config directive to 1. This is because tables are represented by files which are case sensitive in Linux.

Especially beware of development on Windows which is not case sensitive and deploying to production where it is. For example:

"SELECT * from mytable" 

against table myTable will succeed in Windows but fail in Linux, again, unless the abovementioned directive is set.

Reference here: http://dev.mysql.com/doc/refman/5.0/en/identifier-case-sensitivity.html

You can use VLOOKUP, but this requires a wrapper function to return True or False. Not to mention it is (relatively) slow. Use COUNTIF or MATCH instead.

Fill down this formula in column K next to the existing values in column I (from I1 to I2691):

=COUNTIF(<entire column E range>,<single column I value>)>0
=COUNTIF($E$1:$E$99504,$I1)>0

You can also use MATCH:

=NOT(ISNA(MATCH(<single column I value>,<entire column E range>)))
=NOT(ISNA(MATCH($I1,$E$1:$E$99504,0)))

Technically they function the same if you’re using SQL Server AKA T-SQL. If you're using it in stored procedures there is no performance reason to use one over the other. It then comes down to personal preference. I prefer to use <> as it is ANSI compliant.

You can find links to the various ANSI standards at...

http://en.wikipedia.org/wiki/SQL

Are you looking for the following plot:

library(ggplot2) 
l<-df[df$ID %in% c("P1","P3"),]
myplot<-ggplot(l)+geom_line(aes(Value1, Value2, group=ID, colour=ID))

Starting with Vue2, the triple braces were deprecated, you are to use v-html.

<div v-html="task.html_content"> </div>

It is unclear from the documentation link as to what we are supposed to place inside v-html, your variables goes inside v-html.

Also, v-html works only with <div> or <span> but not with <template>.

If you want to see this live in an app, click here.

This happens when you index a row/column with a number that is larger than the dimensions of your dataframe. For instance, getting the eleventh column when you have only three.

import pandas as pd

df = pd.DataFrame({'Name': ['Mark', 'Laura', 'Adam', 'Roger', 'Anna'],
                   'City': ['Lisbon', 'Montreal', 'Lisbon', 'Berlin', 'Glasgow'],
                   'Car': ['Tesla', 'Audi', 'Porsche', 'Ford', 'Honda']})

You have 5 rows and three columns:

    Name      City      Car
0   Mark    Lisbon    Tesla
1  Laura  Montreal     Audi
2   Adam    Lisbon  Porsche
3  Roger    Berlin     Ford
4   Anna   Glasgow    Honda

Let's try to index the eleventh column (it doesn't exist):

df.iloc[:, 10] # there is obviously no 11th column

IndexError: single positional indexer is out-of-bounds

If you are a beginner with Python, remember that df.iloc[:, 10] would refer to the eleventh column.

Try using the SO_REUSEADDR socket option before binding the socket.

comSocket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

Edit: I see you're still having trouble with this. There is a case where SO_REUSEADDR won't work. If you try to bind a socket and reconnect to the same destination (with SO_REUSEADDR enabled), then TIME_WAIT will still be in effect. It will however allow you to connect to a different host:port.

A couple of solutions come to mind. You can either continue retrying until you can gain a connection again. Or if the client initiates the closing of the socket (not the server), then it should magically work.

Any future date in JavaScript (postman test uses JavaScript) can be retrieved as:

var dateNow = new Date();  
var twoWeeksFutureDate = new Date(dateNow.setDate(dateNow.getDate() + 14)).toISOString();

postman.setEnvironmentVariable("future-date", twoWeeksFutureDate);

Follow the example --

songs = [
{"title": "happy birthday", "playcount": 4},
{"title": "AC/DC", "playcount": 2},
{"title": "Billie Jean", "playcount": 6},
{"title": "Human Touch", "playcount": 3}
]

print("===========================")
print(f'Songs --> {songs} \n')
title = list(map(lambda x : x['title'], songs))
print(f'Print Title --> {title}')

playcount = list(map(lambda x : x['playcount'], songs))
print(f'Print Playcount --> {playcount}')
print (f'Print Sorted playcount --> {sorted(playcount)}')

# Aliter -
print(sorted(list(map(lambda x: x['playcount'],songs))))

You also can use this:

// GET api/user/firstname/lastname/address
[HttpGet("{firstName}/{lastName}/{address}")]
public string GetQuery(string id, string firstName, string lastName, string address)
{
    return $"{firstName}:{lastName}:{address}";
}

Note: Please refer to metalheart's and metalheart and Mark Hughes for a possibly better approach.

I would say the answer is: you can't. (or at least: you shouldn't). This is not what Webpack is supposed to do. Webpack is a bundler, and it should not be used for other tasks (in this case: copying static files is another task). You should use a tool like Grunt or Gulp to do such tasks. It is very common to integrate Webpack as a Grunt task or as a Gulp task. They both have other tasks useful for copying files like you described, for example, grunt-contrib-copy or gulp-copy.

For other assets (not the index.html), you can just bundle them in with Webpack (that is exactly what Webpack is for). For example, var image = require('assets/my_image.png');. But I assume your index.html needs to not be a part of the bundle, and therefore it is not a job for the bundler.

While this usage of the PageName property on an object does in fact allow you to customize the exported sheet names in Excel, be warned that it can also update your report's namespace definitions, which could affect the ability to redeploy the report to your server.

I had a report that I applied this to within BIDS and it updated my namespace from 2008 to 2010. When I tried to publish the report to a 2008R2 report server, I got an error that the namespace was not valid and had to revert everything back. I am sure that my circumstance may be unique and perhaps this won't always happen, but I thought it worthy to post about. Once I found the problem, this page helped to revert the namespace back (There are tags that must also be removed in addition to resetting the namespace):

http://beatheadagainstwall.blogspot.com/2011/03/invalid-target-namespace-when-deploying.html?showComment=1440647962263#c5741523651495876761

What good is scope (private, protected) if you can just use :: to expose anything?

In Ruby, everything is exposed and everything can be modified from anywhere else.

If you're worried about the fact that classes can be changed from outside the "class definition", then Ruby probably isn't for you.

On the other hand, if you're frustrated by Java's classes being locked down, then Ruby is probably what you're looking for.

SOLUTION :-

Guess, this error is most probably returned by Local Squid deployed in the server.

So, it worked fine and good after replacing localhost by the local_ip in which the ElasticSearch has been deployed.

Another way is to select a column with the columns array:

In [5]: df = pd.DataFrame([[1,2], [3,4]], columns=['a', 'b'])

In [6]: df
Out[6]: 
   a  b
0  1  2
1  3  4

In [7]: df[df.columns[0]]
Out[7]: 
0    1
1    3
Name: a, dtype: int64

This is impossible as you cannot return from an asynchronous call inside a synchronous method.

In this case you need to pass a callback to foo that will receive the return value

function foo(address, fn){
  geocoder.geocode( { 'address': address}, function(results, status) {
     fn(results[0].geometry.location); 
  });
}

foo("address", function(location){
  alert(location); // this is where you get the return value
});

The thing is, if an inner function call is asynchronous, then all the functions 'wrapping' this call must also be asynchronous in order to 'return' a response.

If you have a lot of callbacks you might consider taking the plunge and use a promise library like Q.

The only surefire option to find the current session.save_path value is always to check with phpinfo() in exactly the environment where you want to find out the session storage directory.

Reason: there can be all sorts of things that change session.save_path, either by overriding the php.ini value or by setting it at runtime with ini_set('session.save_path','/path/to/folder');. For example, web server management panels like ISPConfig, Plesk etc. often adapt this to give each website its own directory with session files.

Yes, you could use a transparent div positioned over the iframe area, with a loader gif as only background.

Then you can attach an onload event to the iframe:

 $(document).ready(function() {

   $("iframe#id").load(function() {
      $("#loader-id").hide();
   });
});

Have you tried

document.getElementById('body').style.display = "none";

instead of

document.getElementById('body').style.display = "hidden";?

While there is no denying that jQuery is a powerful tool, it is a really bad idea to use it for such a trivial operation as "get an element's attribute value".

Judging by the current accepted answer, I am going to assume that you were able to add an ID attribute to your element and use that to select it.

With that in mind, here are two pieces of code. First, the code given to you in the Accepted Answer:

$("#ID").attr("name");

And second, the Vanilla JS version of it:

document.getElementById('ID').getAttribute("name");

My results:

• jQuery: 300k operations / second
• JavaScript: 11,000k operations / second

You can test for yourself here. The "plain JavaScript" vesion is over 35 times faster than the jQuery version.

Now, that's just for one operation, over time you will have more and more stuff going on in your code. Perhaps for something particularly advanced, the optimal "pure JavaScript" solution would take one second to run. The jQuery version might take 30 seconds to a whole minute! That's huge! People aren't going to sit around for that. Even the browser will get bored and offer you the option to kill the webpage for taking too long!

As I said, jQuery is a powerful tool, but it should not be considered the answer to everything.

it is very possible to convert JSON using XSLT: you need JSON2SAX deserializer and SAX2JSON serializer.

Sample code in Java: http://www.gerixsoft.com/blog/json/xslt4json

Seems there's an easier way, at least in Kendo UI v2015.2.624:

$('#myDropDownSelector').data('kendoDropDownList').search('Text value to find');

If there's not a match in the dropdown, Kendo appears to set the dropdown to an unselected value, which makes sense.

I couldn't get @Gang's answer to work, but if you swap his value with search, as above, we're golden.

It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment to your bean.

@Autowired
private Environment environment;
....

this.environment.getActiveProfiles();

Note that list and array are different classes. You can do:

del mylist[:]

This will actually modify your existing list. David's answer creates a new list and assigns it to the same variable. Which you want depends on the situation (e.g. does any other variable have a reference to the same list?).

Try:

a = [1,2]
b = a
a = []

and

a = [1,2]
b = a
del a[:]

Print a and b each time to see the difference.

The reason this occurs is because the file is stored in the "cache" of the browser – so there is no need for the browser to request the sheet again. This occurs for most files that your HTML links to – whether they're CDNs or on your server, for example, a stylesheet. A hard refresh will reload the page and send new GET requests to the server (and to external b if needed).

You can also empty the caches in most browsers with the following keyboard shortcuts.

Safari: Cmd+Alt+e

Chrome and Edge: Shift+Cmd+Delete (Mac) and Ctrl+Shift+Del (Windows)

Well, it's clearly not a number since it has dashes in it. The error message and the two comments tell you that it is a factor but the commentators are apparently waiting and letting the message sink in. Dirk is suggesting that you do this:

 EPL2011_12$Date2 <- as.Date( as.character(EPL2011_12$Date), "%d-%m-%y")

After that you can do this:

 EPL2011_12FirstHalf <- subset(EPL2011_12, Date2 > as.Date("2012-01-13") )

R date functions assume the format is either "YYYY-MM-DD" or "YYYY/MM/DD". You do need to compare like classes: date to date, or character to character.

This occurs to the api 28 and above, because doesn't accept http anymore, you need to change if you want to accept http or localhost requests.

When Python parses a function, it notes when a variable assignment is made. When there is an assignment, it assumes by default that that variable is a local variable. To declare that the assignment refers to a global variable, you must use the global declaration.

When you access a variable in a function, its value is looked up using the LEGB scoping rules.

So, the first example

  x = 1
  def inc():
      x += 5
  inc()

produces an UnboundLocalError because Python determined x inside inc to be a local variable,

while accessing x works in your second example

 def inc():
    print x

because here, in accordance with the LEGB rule, Python looks for x in the local scope, does not find it, then looks for it in the extended scope, still does not find it, and finally looks for it in the global scope successfully.

var isDate_ = function(input) {
        var status = false;
        if (!input || input.length <= 0) {
          status = false;
        } else {
          var result = new Date(input);
          if (result == 'Invalid Date') {
            status = false;
          } else {
            status = true;
          }
        }
        return status;
      }

this function returns bool value of whether the input given is a valid date or not. ex:

if(isDate_(var_date)) {
  // statements if the date is valid
} else {
  // statements if not valid
}

I added customBinding to the web.config.

<configuration>
  <system.serviceModel>
    <bindings>
      <customBinding>
        <binding name="CustomSoapBinding">
          <security includeTimestamp="false"
                    authenticationMode="UserNameOverTransport"
                    defaultAlgorithmSuite="Basic256"
                    requireDerivedKeys="false"
                    messageSecurityVersion="WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10">
          </security>
          <textMessageEncoding messageVersion="Soap11"></textMessageEncoding>
          <httpsTransport maxReceivedMessageSize="2000000000"/>
        </binding>
      </customBinding>
    </bindings>
    <client>
      <endpoint address="https://test.com:443/services/testService"
                binding="customBinding"
                bindingConfiguration="CustomSoapBinding"
                contract="testService.test"
                name="test" />
    </client>
  </system.serviceModel>
  <startup>
    <supportedRuntime version="v4.0"
                      sku=".NETFramework,Version=v4.0"/>
  </startup>
</configuration>

After adding customBinding, I can pass username and password to client service like as follows:

service.ClientCridentials.UserName.UserName = "testUser";
service.ClientCridentials.UserName.Password = "testPass";

In this way you can pass username, password in the header to a SOAP WCF Service.

If you execute the following example, you will know the difference between a Throw and a Catch block.

In general terms:

The catch block will handle the Exception

throws will pass the error to his caller.

In the following example, the error occurs in the throwsMethod() but it is handled in the catchMethod().

public class CatchThrow {

private static void throwsMethod() throws NumberFormatException {
    String  intNumber = "5A";

    Integer.parseInt(intNumber);
}

private static void catchMethod() {
    try {

        throwsMethod();

    } catch (NumberFormatException e) {
        System.out.println("Convertion Error");
    }

}

public static void main(String[] args) {
    // TODO Auto-generated method stub

    catchMethod();
}

}

This will do the trick:

SELECT CONVERT(char(10), GetDate(),126)

Try writing the following batch file and executing it:

Echo one
cmd
Echo two
cmd
Echo three
cmd

Only the first two lines get executed. But if you type "exit" at the command prompt, the next two lines are processed. It's a shell loading another.

To be sure that this is not what is happening in your script, just type "exit" when the first command ends.

HTH!

dumps takes an object and produces a string:

>>> a = {'foo': 3}
>>> json.dumps(a)
'{"foo": 3}'

load would take a file-like object, read the data from that object, and use that string to create an object:

with open('file.json') as fh:
    a = json.load(fh)

Note that dump and load convert between files and objects, while dumps and loads convert between strings and objects. You can think of the s-less functions as wrappers around the s functions:

def dump(obj, fh):
    fh.write(dumps(obj))

def load(fh):
    return loads(fh.read())

Redirecting Input

Redirection of input causes the file whose name results from the expansion of word to be opened for reading on file descriptor n, or the standard input (file descriptor 0) if n is not specified.

The general format for redirecting input is:

[n]<word

Redirecting Output

Redirection of output causes the file whose name results from the expansion of word to be opened for writing on file descriptor n, or the standard output (file descriptor 1) if n is not specified. If the file does not exist it is created; if it does exist it is truncated to zero size.

The general format for redirecting output is:

[n]>word

Moving File Descriptors

The redirection operator,

[n]<&digit-

moves the file descriptor digit to file descriptor n, or the standard input (file descriptor 0) if n is not specified. digit is closed after being duplicated to n.

Similarly, the redirection operator

[n]>&digit-

moves the file descriptor digit to file descriptor n, or the standard output (file descriptor 1) if n is not specified.

Ref:

man bash

Type /^REDIRECT to locate to the redirection section, and learn more...

An online version is here: 3.6 Redirections

PS:

Lots of the time, man was the powerful tool to learn Linux.

I was trying to run this on a pi zero. Turns out the pi zero has an armv6l architecture so the above won't work for pi zero or pi one. Alternatively here I learned that miniconda doesn't have a recent version of miniconda. Instead I used the same instructions posted here to install berryconda3

Conda is now working. Hope this helps those of you interested in running conda on the pi zero!

Use the bootstrap built in classes input-large, input-medium, ... : <input type="text" class="input-large search-query">

Or use your own css:

1. Give the element a unique classname class="search-query input-mysize"
2. Add this in your css file (not the bootstrap.less or css files):
   .input-mysize { width: 150px }

div {
     background: #dbdbdb;
    -webkit-transition: .5s all;   
    -webkit-transition-delay: 5s; 
    -moz-transition: .5s all;   
    -moz-transition-delay: 5s; 
    -ms-transition: .5s all;   
    -ms-transition-delay: 5s; 
    -o-transition: .5s all;   
    -o-transition-delay: 5s; 
    transition: .5s all;   
    transition-delay: 5s; 
}

div:hover {
    background:#5AC900;
    -webkit-transition-delay: 0s;
    -moz-transition-delay: 0s;
    -ms-transition-delay: 0s;
    -o-transition-delay: 0s;
    transition-delay: 0s;
}

This will add a transition delay, which will be applicable to almost every browser..

If your computer is on a domain, you can see Windows Password Rescuer Advanced, http://www.daossoft.com/documents/how-to-reset-windows-domian-account-password.html

You asked for differences, but you can’t quite compare those two.

Note that <meta http-equiv="content-language" content="es"> is obsolete and removed in HTML5. It was used to specify “a document-wide default language”, with its http-equiv attribute making it a pragma directive (which simulates an HTTP response header like Content-Language that hasn’t been sent from the server, since it cannot override a real one).

Regarding <meta name="language" content="Spanish">, you hardly find any reliable information. It’s non-standard and was probably invented as a SEO makeshift.

However, the HTML5 W3C Recommendation encourages authors to use the lang attribute on html root elements (attribute values must be valid BCP 47 language tags):

<!DOCTYPE html>
<html lang="es-ES">
    <head>
        …

Anyway, if you want to specify the content language to instruct search engine robots, you should consider this quote from Google Search Console Help on multilingual sites:

Google uses only the visible content of your page to determine its language. We don’t use any code-level language information such as lang attributes.

I like:

git format-patch HEAD~<N>

where <N> is number of last commits to save as patches.

The details how to use the command are in the DOC

UPD
Here you can find how to apply them then.

UPD For those who did not get the idea of format-patch
Add alias:

git config --global alias.make-patch '!bash -c "cd ${GIT_PREFIX};git add .;git commit -m ''uncommited''; git format-patch HEAD~1; git reset HEAD~1"'

Then at any directory of your project repository run:

git make-patch

This command will create 0001-uncommited.patch at your current directory. Patch will contain all the changes and untracked files that are visible to next command:

git status .

I feel the simplest way would be

 from matplotlib import pyplot;
 from pylab import genfromtxt;  
 mat0 = genfromtxt("data0.txt");
 mat1 = genfromtxt("data1.txt");
 pyplot.plot(mat0[:,0], mat0[:,1], label = "data0");
 pyplot.plot(mat1[:,0], mat1[:,1], label = "data1");
 pyplot.legend();
 pyplot.show();

1. label is the string that is displayed on the legend
2. you can plot as many series of data points as possible before show() to plot all of them on the same graph This is the simple way to plot simple graphs. For other options in genfromtxt go to this url.

Programmatically change UITextField Keyboard type swift 3.0

Adding to jelovirt's answer, you can use number() to convert the value to a number, then round(), floor(), or ceiling() to get a whole integer.

Example

<xsl:variable name="MyValAsText" select="'5.14'"/>
<xsl:value-of select="number($MyValAsText) * 2"/> <!-- This outputs 10.28 -->
<xsl:value-of select="floor($MyValAsText)"/> <!-- outputs 5 -->
<xsl:value-of select="ceiling($MyValAsText)"/> <!-- outputs 6 -->
<xsl:value-of select="round($MyValAsText)"/> <!-- outputs 5 -->

I came across this question as I was looking to install simplejson for Python 2.6. I needed to use the 'object_pairs_hook' of json.load() in order to load a json file as an OrderedDict. Being familiar with more recent versions of Python I didn't realize that the json module for Python 2.6 doesn't include the 'object_pairs_hook' so I had to install simplejson for this purpose. From personal experience this is why i use simplejson as opposed to the standard json module.

The above answer by pl_rock is correct, the only thing I would add is to expect the ARG inside the Dockerfile if not you won't have access to it. So if you are doing

docker build -t essearch/ess-elasticsearch:1.7.6 --build-arg number_of_shards=5 --build-arg number_of_replicas=2 --no-cache .

Then inside the Dockerfile you should add

ARG number_of_replicas
ARG number_of_shards

I was running into this problem, so I hope I help someone (myself) in the future.

The problem is the way you're using forEach(), as it will always return undefined. You're probably looking for the map() method, which returns a new array:

var tifOptions = Object.keys(tifs).map(function(key) {
    return <option value={key}>{tifs[key]}</option>
});

If you still want to use forEach(), you'd have to do something like this:

var tifOptions = [];

Object.keys(tifs).forEach(function(key) {
    tifOptions.push(<option value={key}>{tifs[key]}</option>);
});

Update:

If you're writing ES6, you can accomplish the same thing a bit neater using an arrow function:

const tifOptions = Object.keys(tifs).map(key => 
    <option value={key}>{tifs[key]}</option>
)

Here's a fiddle showing all options mentioned above: https://jsfiddle.net/fs7sagep/

<script>
var todayDate = new Date();
var getTodayDate = todayDate.getDate();
var getTodayMonth =  todayDate.getMonth()+1;
var getTodayFullYear = todayDate.getFullYear();
var getCurrentHours = todayDate.getHours();
var getCurrentMinutes = todayDate.getMinutes();
var getCurrentAmPm = getCurrentHours >= 12 ? 'PM' : 'AM';
getCurrentHours = getCurrentHours % 12;
getCurrentHours = getCurrentHours ? getCurrentHours : 12; 
getCurrentMinutes = getCurrentMinutes < 10 ? '0'+getCurrentMinutes : getCurrentMinutes;
var getCurrentDateTime = getTodayDate + '-' + getTodayMonth + '-' + getTodayFullYear + ' ' + getCurrentHours + ':' + getCurrentMinutes + ' ' + getCurrentAmPm;
alert(getCurrentDateTime);
</script>

If you wish to support different orientations in debug and release builds, write so (see https://developer.android.com/studio/build/gradle-tips#share-properties-with-the-manifest).

In build.gradle of your app folder write:

android {
    ...
    buildTypes {
        debug {
            applicationIdSuffix '.debug'
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            // Creates a placeholder property to use in the manifest.
            manifestPlaceholders = [orientation: "fullSensor"]
        }
        release {
            debuggable true
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            // Creates a placeholder property to use in the manifest.
            manifestPlaceholders = [orientation: "portrait"]
        }
    }
}

Then in AndroidManifest you can use this variable "orientation" in any Activity:

<activity
    android:name=".LoginActivity"
    android:screenOrientation="${orientation}" />

You can add android:configChanges:

manifestPlaceholders = [configChanges: "", orientation: "fullSensor"] in debug and manifestPlaceholders = [configChanges: "keyboardHidden|orientation|screenSize", orientation: "portrait"] in release,

<activity
    android:name=".LoginActivity"
    android:configChanges="${configChanges}"
    android:screenOrientation="${orientation}" />

Please try the below XAML snippet:

<Button Width="300" Height="50">
  <StackPanel Orientation="Horizontal">
    <Image Source="Pictures/img.jpg" Width="20" Height="20"/>
    <TextBlock Text="Blablabla" VerticalAlignment="Center" />
  </StackPanel>
</Button>

In XAML elements are in a tree structure. So you have to add the child control to its parent control. The below code snippet also works fine. Give a name for your XAML root grid as 'MainGrid'.

Image img = new Image();
img.Source = new BitmapImage(new Uri(@"foo.png"));

StackPanel stackPnl = new StackPanel();
stackPnl.Orientation = Orientation.Horizontal;
stackPnl.Margin = new Thickness(10);
stackPnl.Children.Add(img);

Button btn = new Button();
btn.Content = stackPnl;
MainGrid.Children.Add(btn);

Tends to work well from my exprience.

You should use Terms Query

{
    "query" : {
        "terms" : {
            "tags" : ["c", "d"]
        }
    }
}

The purpose of a view is to use the query over and over again. To that end, SQL Server, Oracle, etc. will typically provide a "cached" or "compiled" version of your view, thus improving its performance. In general, this should perform better than a "simple" query, though if the query is truly very simple, the benefits may be negligible.

Now, if you're doing a complex query, create the view.

The error TypeError: 'numpy.ndarray' object is not callable means that you tried to call a numpy array as a function.

Use

Z=XY[0]+XY[1]

Instead of

Z=XY(i,0)+XY(i,1)

If you add helper fields to the coordinates table, you can improve response time of the query.

Like this:

CREATE TABLE `Coordinates` (
`id` INT(10) UNSIGNED NOT NULL COMMENT 'id for the object',
`type` TINYINT(4) UNSIGNED NOT NULL DEFAULT '0' COMMENT 'type',
`sin_lat` FLOAT NOT NULL COMMENT 'sin(lat) in radians',
`cos_cos` FLOAT NOT NULL COMMENT 'cos(lat)*cos(lon) in radians',
`cos_sin` FLOAT NOT NULL COMMENT 'cos(lat)*sin(lon) in radians',
`lat` FLOAT NOT NULL COMMENT 'latitude in degrees',
`lon` FLOAT NOT NULL COMMENT 'longitude in degrees',
INDEX `lat_lon_idx` (`lat`, `lon`)
)    

If you're using TokuDB, you'll get even better performance if you add clustering indexes on either of the predicates, for example, like this:

alter table Coordinates add clustering index c_lat(lat);
alter table Coordinates add clustering index c_lon(lon);

You'll need the basic lat and lon in degrees as well as sin(lat) in radians, cos(lat)*cos(lon) in radians and cos(lat)*sin(lon) in radians for each point. Then you create a mysql function, smth like this:

CREATE FUNCTION `geodistance`(`sin_lat1` FLOAT,
                              `cos_cos1` FLOAT, `cos_sin1` FLOAT,
                              `sin_lat2` FLOAT,
                              `cos_cos2` FLOAT, `cos_sin2` FLOAT)
    RETURNS float
    LANGUAGE SQL
    DETERMINISTIC
    CONTAINS SQL
    SQL SECURITY INVOKER
   BEGIN
   RETURN acos(sin_lat1*sin_lat2 + cos_cos1*cos_cos2 + cos_sin1*cos_sin2);
   END

This gives you the distance.

Don't forget to add an index on lat/lon so the bounding boxing can help the search instead of slowing it down (the index is already added in the CREATE TABLE query above).

INDEX `lat_lon_idx` (`lat`, `lon`)

Given an old table with only lat/lon coordinates, you can set up a script to update it like this: (php using meekrodb)

$users = DB::query('SELECT id,lat,lon FROM Old_Coordinates');

foreach ($users as $user)
{
  $lat_rad = deg2rad($user['lat']);
  $lon_rad = deg2rad($user['lon']);

  DB::replace('Coordinates', array(
    'object_id' => $user['id'],
    'object_type' => 0,
    'sin_lat' => sin($lat_rad),
    'cos_cos' => cos($lat_rad)*cos($lon_rad),
    'cos_sin' => cos($lat_rad)*sin($lon_rad),
    'lat' => $user['lat'],
    'lon' => $user['lon']
  ));
}

Then you optimize the actual query to only do the distance calculation when really needed, for example by bounding the circle (well, oval) from inside and outside. For that, you'll need to precalculate several metrics for the query itself:

// assuming the search center coordinates are $lat and $lon in degrees
// and radius in km is given in $distance
$lat_rad = deg2rad($lat);
$lon_rad = deg2rad($lon);
$R = 6371; // earth's radius, km
$distance_rad = $distance/$R;
$distance_rad_plus = $distance_rad * 1.06; // ovality error for outer bounding box
$dist_deg_lat = rad2deg($distance_rad_plus); //outer bounding box
$dist_deg_lon = rad2deg($distance_rad_plus/cos(deg2rad($lat)));
$dist_deg_lat_small = rad2deg($distance_rad/sqrt(2)); //inner bounding box
$dist_deg_lon_small = rad2deg($distance_rad/cos(deg2rad($lat))/sqrt(2));

Given those preparations, the query goes something like this (php):

$neighbors = DB::query("SELECT id, type, lat, lon,
       geodistance(sin_lat,cos_cos,cos_sin,%d,%d,%d) as distance
       FROM Coordinates WHERE
       lat BETWEEN %d AND %d AND lon BETWEEN %d AND %d
       HAVING (lat BETWEEN %d AND %d AND lon BETWEEN %d AND %d) OR distance <= %d",
  // center radian values: sin_lat, cos_cos, cos_sin
       sin($lat_rad),cos($lat_rad)*cos($lon_rad),cos($lat_rad)*sin($lon_rad),
  // min_lat, max_lat, min_lon, max_lon for the outside box
       $lat-$dist_deg_lat,$lat+$dist_deg_lat,
       $lon-$dist_deg_lon,$lon+$dist_deg_lon,
  // min_lat, max_lat, min_lon, max_lon for the inside box
       $lat-$dist_deg_lat_small,$lat+$dist_deg_lat_small,
       $lon-$dist_deg_lon_small,$lon+$dist_deg_lon_small,
  // distance in radians
       $distance_rad);

EXPLAIN on the above query might say that it's not using index unless there's enough results to trigger such. The index will be used when there's enough data in the coordinates table. You can add FORCE INDEX (lat_lon_idx) to the SELECT to make it use the index with no regards to the table size, so you can verify with EXPLAIN that it is working correctly.

With the above code samples you should have a working and scalable implementation of object search by distance with minimal error.

I went through the exercise to capture low level packet exchange, and found that network connection is only triggered by operations like getInputStream, getOutputStream, getResponseCode, getResponseMessage etc.

Here is the packet exchange captured when I try to write a small program to upload file to Dropbox.

Below is my toy program and annotation

    /* Create a connection LOCAL object,
     * the openConnection() function DOES NOT initiate
     * any packet exchange with the remote server.
     * 
     * The configurations only setup the LOCAL
     * connection object properties.
     */
    HttpURLConnection connection = (HttpURLConnection) dst.openConnection();
    connection.setDoOutput(true);
    connection.setRequestMethod("POST");
    ...//headers setup
    byte[] testContent = {0x32, 0x32};

    /**
     * This triggers packet exchange with the remote
     * server to create a link. But writing/flushing
     * to a output stream does not send out any data.
     * 
     * Payload are buffered locally.
     */
    try (BufferedOutputStream outputStream = new BufferedOutputStream(connection.getOutputStream())) {
        outputStream.write(testContent);
        outputStream.flush();
    }

    /**
     * Trigger payload sending to the server.
     * Client get ALL responses (including response code,
     * message, and content payload) 
     */
    int responseCode = connection.getResponseCode();
    System.out.println(responseCode);

    /* Here no further exchange happens with remote server, since
     * the input stream content has already been buffered
     * in previous step
     */
    try (InputStream is = connection.getInputStream()) {
        Scanner scanner = new Scanner(is);
        StringBuilder stringBuilder = new StringBuilder();
        while (scanner.hasNextLine()) {
        stringBuilder.append(scanner.nextLine()).append(System.lineSeparator());
        }
    }

    /**
     * Trigger the disconnection from the server.
     */
    String responsemsg = connection.getResponseMessage();
    System.out.println(responsemsg);
    connection.disconnect();

As ant31 already pointed out you can use the synchronize module to this. By default, the module transfers files between the control machine and the current remote host (inventory_host), however that can be changed using the task's delegate_to parameter (it's important to note that this is a parameter of the task, not of the module).

You can place the task on either ServerA or ServerB, but you have to adjust the direction of the transfer accordingly (using the mode parameter of synchronize).

Placing the task on ServerB

- hosts: ServerB
  tasks:
    - name: Transfer file from ServerA to ServerB
      synchronize:
        src: /path/on/server_a
        dest: /path/on/server_b
      delegate_to: ServerA

This uses the default mode: push, so the file gets transferred from the delegate (ServerA) to the current remote (ServerB).

This might sound like strange, since the task has been placed on ServerB (via hosts: ServerB). However, one has to keep in mind that the task is actually executed on the delegated host, which in this case is ServerA. So pushing (from ServerA to ServerB) is indeed the correct direction. Also remember that we cannot simply choose not to delegate at all, since that would mean that the transfer happens between the control machine and ServerB.

Placing the task on ServerA

- hosts: ServerA
  tasks:
    - name: Transfer file from ServerA to ServerB
      synchronize:
        src: /path/on/server_a
        dest: /path/on/server_b
        mode: pull
      delegate_to: ServerB

This uses mode: pull to invert the transfer direction. Again, keep in mind that the task is actually executed on ServerB, so pulling is the right choice.

Current month:

SELECT * FROM jokes WHERE YEAR(date) = YEAR(NOW()) AND MONTH(date)=MONTH(NOW());

Current week:

SELECT * FROM jokes WHERE WEEKOFYEAR(date) = WEEKOFYEAR(NOW());

Current day:

SELECT * FROM jokes WHERE YEAR(date) = YEAR(NOW()) AND MONTH(date) = MONTH(NOW()) AND DAY(date) = DAY(NOW());

This will select only current month, really week and really only today :-)

Try this code:

CONVERT(varchar(15), date_started, 103)

I had a similar problem and this scale worked for me like a charm:

breaks = 10**(1:10)
scale_y_log10(breaks = breaks, labels = comma(breaks))

as you want the intermediate levels, too (10^3.5), you need to tweak the formatting:

breaks = 10**(1:10 * 0.5)
m <- ggplot(diamonds, aes(y = price, x = color)) + geom_boxplot()
m + scale_y_log10(breaks = breaks, labels = comma(breaks, digits = 1))

   url = 'http://example.com/some/cookie/setting/url'
   r = requests.get(url)
   r.cookies
   

   {'example_cookie_name': 'example_cookie_value'}

2. give cookie back to server on subsequent request

   url = 'http://httpbin.org/cookies'
   cookies = dict(cookies_are='working')
   r = requests.get(url, cookies=cookies)`
   

git reflog

• Find your commit sha in the list then copy and paste it into this command:

git cherry-pick <the sha>

Another solution if the list contains static values.

eg: checking for a valid value from a list of valid values:

func IsValidCategory(category string) bool {
    switch category {
    case
        "auto",
        "news",
        "sport",
        "music":
        return true
    }
    return false
}

A semaphore is a signaling mechanism used to coordinate between threads. Example: One thread is downloading files from the internet and another thread is analyzing the files. This is a classic producer/consumer scenario. The producer calls signal() on the semaphore when a file is downloaded. The consumer calls wait() on the same semaphore in order to be blocked until the signal indicates a file is ready. If the semaphore is already signaled when the consumer calls wait, the call does not block. Multiple threads can wait on a semaphore, but each signal will only unblock a single thread.

A counting semaphore keeps track of the number of signals. E.g. if the producer signals three times in a row, wait() can be called three times without blocking. A binary semaphore does not count but just have the "waiting" and "signalled" states.

A mutex (mutual exclusion lock) is a lock which is owned by a single thread. Only the thread which have acquired the lock can realease it again. Other threads which try to acquire the lock will be blocked until the current owner thread releases it. A mutex lock does not in itself lock anything - it is really just a flag. But code can check for ownership of a mutex lock to ensure that only one thread at a time can access some object or resource.

A monitor is a higher-level construct which uses an underlying mutex lock to ensure thread-safe access to some object. Unfortunately the word "monitor" is used in a few different meanings depending on context and platform and context, but in Java for example, a monitor is a mutex lock which is implicitly associated with an object, and which can be invoked with the synchronized keyword. The synchronized keyword can be applied to a class, method or block and ensures only one thread can execute the code at a time.

DFS APPROACH WITH A CONDITION(parent != next node) Let's see the code and then understand what's going on :

bool Graph::isCyclicUtil(int v, bool visited[], int parent) 
{ 
    // Mark the current node as visited 
    visited[v] = true; 

    // Recur for all the vertices adjacent to this vertex 
    list<int>::iterator i; 
    for (i = adj[v].begin(); i != adj[v].end(); ++i) 
    { 
        // If an adjacent is not visited, then recur for that adjacent 
        if (!visited[*i]) 
        { 
           if (isCyclicUtil(*i, visited, v)) 
              return true; 
        } 

        // If an adjacent is visited and not parent of current vertex, 
        // then there is a cycle. 
        else if (*i != parent) 
           return true; 
    } 
    return false; 
} 

The above code explains itself but I will try to explain one condition i.e *i != parent Here if suppose graph is

1--2

Then when we are at 1 and goes to 2, the parent for 2 becomes 1 and when we go back to 1 as 1 is in adj matrix of 2 then since next vertex 1 is also the parent of 2 Therefore cycle will not be detected for the immediate parent in this DFS approach. Hence Code works fine

Short answer

The favicon is supposed to be a set of 16x16, 32x32 and 48x48 pictures in ICO format. ICO format is different than PNG. Non-square pictures are not supported.

To generate the favicon, for many reasons explained below, I advise you to use this favicon generator. Full disclosure: I'm the author of this site.

Long, comprehensive answer

Favicon must be square. Desktop browsers and Apple iOS do not support non-square icons.

The favicon is supported by several files:

• A favicon.ico icon.
• Some other PNG icons.

In order to get the best results across desktop browsers (Windows/IE, MacOS/Safari, etc.), you need to combine both types of icons.

favicon.ico

Although all desktop browsers can deal with this icon, it is primarily for older version of IE.

The ICO format is different of the PNG format. This point is tricky because some browsers are smart enough to process a PNG picture correctly, even when it was wrongly renamed with an ICO extension.

An ICO file can contain several pictures and Microsoft recommends to put 16x16, 32x32 and 48x48 versions of the icon in favicon.ico. For example, IE will use the 16x16 version for the address bar, and the 32x32 for a task bar shortcut.

Declare the favicon with:

<link rel="icon" href="/path/to/icons/favicon.ico">

However, it is recommended to place favicon.ico in the root directory of the web site and to not declare it at all and let the modern browsers pick the PNG icons.

PNG icons

Modern desktop browsers (IE11, recent versions of Chrome, Firefox...) prefer to use PNG icons. The usual expected sizes are 16x16, 32x32 and "as big as possible". For example, MacOS/Safari uses the 196x196 icon if it is the biggest it can find.

What are the recommended sizes? Pick your favorite platforms:

• Most desktop browsers: 16x16, 32x32, "as big as possible"
• Android Chrome: 192x192
• Google TV: 96x96
• ... and others that are more or less documented.

The PNG icons are declared with:

<link rel="icon" type="image/png" href="/path/to/icons/favicon-16x16.png" sizes="16x16">
<link rel="icon" type="image/png" href="/path/to/icons/favicon-32x32.png" sizes="32x32">
...

Beware: Firefox does not support the sizes attribute and uses the last PNG icon it finds. Make sure to declare the 32x32 picture last: it is good enough for Firefox, and that will prevent it from downloading a big picture it does not need. edit: fixed in 2016.

Also note that Chrome does not support the sizes attribute and tends to load all declared icons. Better not declare too many icons. edit: fixed in 2018.

Mobile platforms

This question is about desktop favicon so there is no need to delve too much in this topic.

Apple defines touch icon for the iOS platform. iOS does not support non-square icon. It simply rescales non-square pictures to make them square (look for the Kioskea example).

Android Chrome relies on the Apple touch icon and also defines a 192x192 PNG icon.

Microsoft defines the tile picture and the browserconfig.xml file.

Conclusion

Generating a favicon that works everywhere is quite complex. I advise you to use this favicon generator. Full disclosure: I'm the author of this site.

    return @res
end

There is actually a python library called dataframe_image Just do a

pip install dataframe_image

Do the imports

import pandas as pd
import numpy as np
import dataframe_image as dfi
df = pd.DataFrame(np.random.randn(6, 6), columns=list('ABCDEF'))

and style your table if you want by:

df_styled = df.style.background_gradient() #adding a gradient based on values in cell

and finally:

dfi.export(df_styled,"mytable.png")

I had this same issue when trying to handle popping alerts and fading them. I searched around various places and found this to be my solution. Adding and removing the 'in' class fixed my issue.

window.setTimeout(function() { // hide alert message
    $("#alert_message").removeClass('in'); 

}, 5000);

When using .remove() and similarly the .alert('close') solution I seemed to hit an issue with the alert being removed from the document, so if I wanted to use the same alert div again I was unable to. This solution means the alert is reusable without refreshing the page. (I was using aJax to submit a form and present feedback to the user)

    $('#Some_Button_Or_Event_Here').click(function () { // Show alert message
        $('#alert_message').addClass('in'); 
    });

First of all you should create property with employee details in the Employee class:

public class Employee
{
    public Employee()
    {
        EmployeeDetails = new EmployeeDetails();
        EmployeeDetails.EmpID = 123;
        EmployeeDetails.EmpName = "ABC";
    }

    public EmployeeDetails EmployeeDetails { get; set; }
}

If you don't do that, you will create instance of object in Employee constructor and you lose reference to it.

In the XAML you should create instance of Employee class, and after that you can assign it to DataContext.

Your XAML should look like this:

<Window x:Class="SampleApplication.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525"
    xmlns:local="clr-namespace:SampleApplication"
   >
    <Window.Resources>
        <local:Employee x:Key="Employee" />
    </Window.Resources>
    <Grid DataContext="{StaticResource Employee}">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto" />
            <ColumnDefinition Width="200" />
        </Grid.ColumnDefinitions>

        <Label Grid.Row="0" Grid.Column="0" Content="ID:"/>
        <Label Grid.Row="1" Grid.Column="0" Content="Name:"/>
        <TextBox Grid.Column="1" Grid.Row="0" Margin="3" Text="{Binding EmployeeDetails.EmpID}" />
        <TextBox Grid.Column="1" Grid.Row="1" Margin="3" Text="{Binding EmployeeDetails.EmpName}" />
    </Grid>
</Window>

Now, after you created property with employee details you should binding by using this property:

Text="{Binding EmployeeDetails.EmpID}"

What you are looking for is the wait method.

/^[-\w\s]+$/

\w matches letters, digits, and underscores

\s matches spaces, tabs, and line breaks

- matches the hyphen (if you have hyphen in your character set example [a-z], be sure to place the hyphen at the beginning like so [-a-z])

I tried various ways. What worked for me was this:

Convert.ToDateTime(data, CultureInfo.InvariantCulture);

data for me was times like this 9/24/2017 9:31:34 AM

@AlexanderMP's answer is correct, but you can also consider handling nulls with coalesce:

declare @CodeNameString  nvarchar(max)
set @CodeNameString = null
SELECT @CodeNameString = Coalesce(@CodeNameString + ', ', '') + cast(CodeName as varchar) from AccountCodes  
select @CodeNameString

if(!empty($youtube) && empty($link)) {

}
else if(empty($youtube) && !empty($link)) {

}
else if(empty($youtube) && empty($link)) {
}

lets put this in a simple term. An element is a set of opening and closing tags in use.

Element

<h1>...</h1>

Tag H1 opening tag

<h1>

H1 closing tag

</h1>

I Concatenated my formula as normal but at the start I had '= instead of =.

Then I copy and paste as text to where I need it. Then I highlight the section saved as text and press ctrl + H to find and replace.
I replace '= with = and all of my functions are active.

Its a few stages but it avoids VBA.

I hope this helps,

In case you use Angular's FormBuilder this is the way to go (at least for Angular 9):

HTML view: yourelement.component.html

Use [formGroup] to reference form variable, and use formControlName to reference form's inner variable (both defined in TypeScrit file). Preferably, use [value] to reference some type of option ID.

<form [formGroup] = "uploadForm" (ngSubmit)="onSubmit()">
   . . .html
   <select class="form-control" formControlName="form_variable" required>
       <option *ngFor="let elem of list" [value]="elem.id">{{elem.nanme}}</option>
   </select>
   . . .
</form>

Logic file: yourelement.component.ts

In the initialization of FormBuilderobject, in ngOnInit() function, set the default value you desire to be as default selected.

. . .
// Remember to add imports of "FormsModule" and "ReactiveFormsModule" to app.module.ts
import { FormBuilder, FormGroup } from '@angular/forms';
. . .

export class YourElementComponent implements OnInit {
  // <form> variable
  uploadForm: FormGroup;

  constructor( private formBuilder: FormBuilder ){}

  ngOnInit() {
     this.uploadForm = this.formBuilder.group({
          . . .
          form_variable: ['0'], // <--- Here is the "value" ID of default selected
          . . .
     });
  }
}

My solution for rounding specific corners of UIView and UITextFiels in swift is to use

.layer.cornerRadius

and

layer.maskedCorners

of actual UIView or UITextFields.

Example:

fileprivate func inputTextFieldStyle() {
        inputTextField.layer.masksToBounds = true
        inputTextField.layer.borderWidth = 1
        inputTextField.layer.cornerRadius = 25
        inputTextField.layer.maskedCorners = [.layerMaxXMaxYCorner,.layerMaxXMinYCorner]
        inputTextField.layer.borderColor = UIColor.white.cgColor
    }

And by using

.layerMaxXMaxYCorner

and

.layerMaxXMinYCorner

, I can specify top right and bottom right corner of the UITextField to be rounded.

You can see the result here:

Q1.) Assuming process B tries to take ownership of the same mutex you locked in process A (you left that out of your pseudocode) then no, process B cannot access sharedResource while the mutex is locked since it will sit waiting to lock the mutex until it is released by process A. It will return from the mutex_lock() function when the mutex is locked (or when an error occurs!)

Q2.) In Process B, ensure you always lock the mutex, access the shared resource, and then unlock the mutex. Also, check the return code from the mutex_lock( pMutex ) routine to ensure that you actually own the mutex, and ONLY unlock the mutex if you have locked it. Do the same from process A.

Both processes should basically do the same thing when accessing the mutex.
lock() If the lock succeeds, then { access sharedResource unlock() }

Q3.) Yes, there are lots of diagrams: =) https://www.google.se/search?q=mutex+thread+process&rlz=1C1AFAB_enSE487SE487&um=1&ie=UTF-8&hl=en&tbm=isch&source=og&sa=N&tab=wi&ei=ErodUcSmKqf54QS6nYDoAw&biw=1200&bih=1730&sei=FbodUbPbB6mF4ATarIBQ

Browsers with HTML5 support has files property for input type. This will of course not work in older IE versions.

var inpFiles = document.getElementById('#fileID');
for (var i = 0; i < inpFiles.files.length; ++i) {
    var size = inpFiles.files.item(i).size;
    alert("File Size : " + size);
}

In phpmyadmin, If you need to add a boolean datatype column to an existing table with default value true:

I'd like to provide an alternate, easier solution that is specific to FontAwesome. If you're using a different iconic font, JOPLOmacedo's answer is still perfectly fine for use.

FontAwesome now handles list styles internally with CSS classes.

Here's the official example:

<ul class="fa-ul">
  <li><span class="fa-li"><i class="fas fa-check-square"></i></span>List icons can</li>
  <li><span class="fa-li"><i class="fas fa-check-square"></i></span>be used to</li>
  <li><span class="fa-li"><i class="fas fa-spinner fa-pulse"></i></span>replace bullets</li>
  <li><span class="fa-li"><i class="far fa-square"></i></span>in lists</li>
</ul>

I ran into this problem when trying to implement markdown using PHP.

Since the user generated links created with markdown need to open in a new tab but site links need to stay in tab I changed markdown to only generate links that open in a new tab. So not all links on the page link out, just the ones that use markdown.

In markdown I changed all the link output to be <a target='_blank' href="..."> which was easy enough using find/replace.

import requests

site_request = requests.get("https://abhiunix.in")

site_response = str(site_request.content)

print(site_response)

You can do it either way.

I found a slight alteration on what @jota3 suggested worked perfectly for me.

var intersections = array1.filter(e => array2.indexOf(e) !== -1);

Hope this helps!

You can create a utility class to check if the class represents any Collection, Map or Array

  public static boolean isCollection(Class<?> rawPropertyType) {
        return Collection.class.isAssignableFrom(rawPropertyType) || 
               Map.class.isAssignableFrom(rawPropertyType) || 
               rawPropertyType.isArray();
 }

To check if LocalDb is installed or not:

• run cmd and type in sqllocaldb i this should give you the installed sqllocaldb instances if found.
• Run SSMS (SQL Server Management Studio).
• Try to connect to this instance (localdb)\V11.0 using windows authentication.

If an error is raised Cannot connect to (localdb)\V11.0. change the instance name to (localdb)\MSSQLLocalDB and try again to connect, if you still get the same error.

Follow these steps to install LocalDb:

• Close SSMS.
• Close VS (Visual Studio) if it's running.
• Go to Start Menu and type in search sqlLocalDb.
• From the results that appears choose sqlLocalDb.msi and click it.
• SQL setup will start to install LocalDB

after finishing the installation re-run SSMS and try connecting to either of the instances (localdb)\V11.0 or (localdb)\MSSQLLocalDB, one of it should work depending on what Visual Studio version you have.

You can also verify that localdb is installed using Visual Studio by simply creating new sql file and go to the connect icon on the top header of the file which by default lists all the servers you can connect to including localdb if installed.

In addition to the above mentioned ways of finding if localdb is installed, you can also use the MS windows power shell or windows command processor CMD or even NuGet package manager console on your server machine and run these commands sqllocaldb i and sqllocaldb v that will show you the localdb name if it is installed and the MSSQL server version installed and running on your machine.

This is how I would do it.

$randnum1 = mt_rand(1,20);

$nomatch = 0;

while($nomatch == 0){

$randnum2 = mt_rand(1,20);

if($randnum2 != $randnum1){

$nomatch = 1;

}

}

$nomatch = 0;

while($nomatch == 0){

$randnum3 = mt_rand(1,20);

if(($randnum3 != $randnum1)and($randnum3 != $randnum2)){

$nomatch = 1;

}

}

Then you can echo the results to check

echo "Random numbers are " . $randnum1 . "," . $randnum2 . ", and " . $randnum3 . "\n";

In this particular example, you can use:

#container:hover #cube {
    background-color: yellow;   
}

This example only works since cube is a child of container. For more complicated scenarios, you'd need to use different CSS, or use JavaScript.

The options discussed above won't work because they are not part of the CSS specification (it is jQuery extension). Having spent 2-3 days digging around for information, I found that the only way to select the Text of the selected option from the drop down is:

{ $("select", id:"Some_ID").find("option[selected='selected']")}

Refer to additional notes below: Because :selected is a jQuery extension and not part of the CSS specification, queries using :selected cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :selected to select elements, first select the elements using a pure CSS selector, then use .filter(":selected"). (copied from: http://api.jquery.com/selected-selector/)

In C# 8.0 and above, you can use the range operator .. as in

var s = "header-THE_TARGET_STRING.7z";
var from = s.IndexOf("-") + "-".Length;
var to = s.IndexOf(".7z");
var versionString = s[from..to];  // THE_TARGET_STRING

See documentation for details.

Use the approach where you send username and password in URL Request:

http://username:[email protected]

So just to make it more clear. The username is username password is password and the rest is usual URL of your test web

Works for me without needing any tweaks.

Sample Java code:

public static final String TEST_ENVIRONMENT = "the-site.com";
private WebDriver driver;

public void login(String uname, String pwd){
  String URL = "http://" + uname + ":" + pwd + "@" + TEST_ENVIRONMENT;
  driver.get(URL);
}

@Test
public void testLogin(){
   driver = new FirefoxDriver();
   login("Pavel", "UltraSecretPassword");
   //Assert...
}

Note that --no-ri and --no-rdoc have been deprecated according to the new guides. The recommended way is to use --no-document in ~/.gemrc or /etc/gemrc.

install: --no-document
update: --no-document

or

gem: --no-document

Your syntax is incorrect. The var keyword in your for loop must be followed by a variable name, in this case its propName

var propValue;
for(var propName in nyc) {
    propValue = nyc[propName]

    console.log(propName,propValue);
}

I suggest you have a look here for some basics:

Since none for these solutions support the latest version of PDFMiner I wrote a simple solution that will return text of a pdf using PDFMiner. This will work for those who are getting import errors with process_pdf

import sys
from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.pdfpage import PDFPage
from pdfminer.converter import XMLConverter, HTMLConverter, TextConverter
from pdfminer.layout import LAParams
from cStringIO import StringIO

def pdfparser(data):

    fp = file(data, 'rb')
    rsrcmgr = PDFResourceManager()
    retstr = StringIO()
    codec = 'utf-8'
    laparams = LAParams()
    device = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
    # Create a PDF interpreter object.
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    # Process each page contained in the document.

    for page in PDFPage.get_pages(fp):
        interpreter.process_page(page)
        data =  retstr.getvalue()

    print data

if __name__ == '__main__':
    pdfparser(sys.argv[1])  

See below code that works for Python 3:

import sys
from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.pdfpage import PDFPage
from pdfminer.converter import XMLConverter, HTMLConverter, TextConverter
from pdfminer.layout import LAParams
import io

def pdfparser(data):

    fp = open(data, 'rb')
    rsrcmgr = PDFResourceManager()
    retstr = io.StringIO()
    codec = 'utf-8'
    laparams = LAParams()
    device = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
    # Create a PDF interpreter object.
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    # Process each page contained in the document.

    for page in PDFPage.get_pages(fp):
        interpreter.process_page(page)
        data =  retstr.getvalue()

    print(data)

if __name__ == '__main__':
    pdfparser(sys.argv[1])  

Yes, that is possible. The challenge, however, is to do their layout properly. The easiest way to do it would be to have an AbsoluteLayout and then put the two images where you want them to be. You don't need to do anything special for the transparent png except having it added later to the layout.

I fixed it by moving the start() function inside the dismiss completion block:

self.tabBarController.dismiss(animated: false) {
  self.start()
}

Start contains two calls to self.present() one for a UINavigationController and another one for a UIImagePickerController.

That fixed it for me.

You can submit form by just clicking on checkbox by simple method in JavaScript. Inside form tag or Input attribute add following attribute:

    onchange="this.form.submit()"

Example:

<form>
      <div>
           <input type="checkbox">
      </div>
</form>

In case anyone else finds this thread with my problem -- I was using an "integer" column type in MySQL. The row I was attempting to insert had a primary key with a value larger than allowed by integer. Switching to "bigint" fixed the problem.

Use the command:

git rev-parse HEAD

For the short version:

git rev-parse --short HEAD

easiest way I found was to convert to HEX instead of a string. If it works for you:

$hex = bin2hex($bin); // It will convert a binary data to its hex representation

$bin = pack("H*" , $hex); // It will convert a hex to binary

OR

$bin = hex2bin($hex); // Available only on PHP 5.4

Or you could do it the evil way.

var a = [1,2,3,4,5,6,7,8,9];

sum = eval(a.join("+"));

;)

Nothing else worked for me except, setting the path as:

C:\Program Files\Microsoft Visual Studio\2017\BuildTools\MSBuild\15.0

    <style>
    background: url(images/Untitled-2.fw.png);
background-repeat:no-repeat;
background-position:center;
background-size: cover;
    </style>

Use order by like this:

return User::orderBy('name', 'DESC')
    ->orderBy('surname', 'DESC')
    ->orderBy('email', 'DESC')
    ...
    ->get();

Simplified version for Oracle. If you don't want to create OracleParameter

var sql = "Update [User] SET FirstName = :p0 WHERE Id = :p1";
context.Database.ExecuteSqlCommand(sql, firstName, id);

As Moneer Kamal said, you can do that simply:

SELECT id, client_id FROM order 
WHERE rownum <= 100
ORDER BY create_time DESC;

Notice that the ordering is done after getting the 100 row. This might be useful for who does not want ordering.

The algorithm you are using, "AES", is a shorthand for "AES/ECB/NoPadding". What this means is that you are using the AES algorithm with 128-bit key size and block size, with the ECB mode of operation and no padding.

In other words: you are only able to encrypt data in blocks of 128 bits or 16 bytes. That's why you are getting that IllegalBlockSizeException exception.

If you want to encrypt data in sizes that are not multiple of 16 bytes, you are either going to have to use some kind of padding, or a cipher-stream. For instance, you could use CBC mode (a mode of operation that effectively transforms a block cipher into a stream cipher) by specifying "AES/CBC/NoPadding" as the algorithm, or PKCS5 padding by specifying "AES/ECB/PKCS5", which will automatically add some bytes at the end of your data in a very specific format to make the size of the ciphertext multiple of 16 bytes, and in a way that the decryption algorithm will understand that it has to ignore some data.

In any case, I strongly suggest that you stop right now what you are doing and go study some very introductory material on cryptography. For instance, check Crypto I on Coursera. You should understand very well the implications of choosing one mode or another, what are their strengths and, most importantly, their weaknesses. Without this knowledge, it is very easy to build systems which are very easy to break.

Update: based on your comments on the question, don't ever encrypt passwords when storing them at a database!!!!! You should never, ever do this. You must HASH the passwords, properly salted, which is completely different from encrypting. Really, please, don't do what you are trying to do... By encrypting the passwords, they can be decrypted. What this means is that you, as the database manager and who knows the secret key, you will be able to read every password stored in your database. Either you knew this and are doing something very, very bad, or you didn't know this, and should get shocked and stop it.

DELETE FROM on_search WHERE search_date < NOW() - INTERVAL N DAY

Whats about:

$string = trim( str_replace( PHP_EOL, ' ', $string ) );

This should be a pretty robust solution because \n doesn't work correctly in all systems if i'm not wrong ...

I was getting the same problem on Spring Tool Suite 3.2 and changed the version of jstl to 1.2 (from 1.1.2) manually when adding it to the dependency list, and the error got disappeared.

1. Can someone give a simple definition of what Record is?

A Record<K, T> is an object type whose property keys are K and whose property values are T. That is, keyof Record<K, T> is equivalent to K, and Record<K, T>[K] is (basically) equivalent to T.

2. Is Record<K,T> merely a way of saying "all properties on this object will have type T"? Probably not all objects, since K has some purpose...

As you note, K has a purpose... to limit the property keys to particular values. If you want to accept all possible string-valued keys, you could do something like Record<string, T>, but the idiomatic way of doing that is to use an index signature like { [k: string]: T }.

3. Does the K generic forbid additional keys on the object that are not K, or does it allow them and just indicate that their properties are not transformed to T?

It doesn't exactly "forbid" additional keys: after all, a value is generally allowed to have properties not explicitly mentioned in its type... but it wouldn't recognize that such properties exist:

declare const x: Record<"a", string>;
x.b; // error, Property 'b' does not exist on type 'Record<"a", string>'

and it would treat them as excess properties which are sometimes rejected:

declare function acceptR(x: Record<"a", string>): void;
acceptR({a: "hey", b: "you"}); // error, Object literal may only specify known properties

and sometimes accepted:

const y = {a: "hey", b: "you"};
acceptR(y); // okay

4. With the given example:

   type ThreeStringProps = Record<'prop1' | 'prop2' | 'prop3', string>
   

   Is it exactly the same as this?:

   type ThreeStringProps = {prop1: string, prop2: string, prop3: string}
   

Yes!

Hope that helps. Good luck!

Obviously I'm a little out of season on this question but for the benefit of the next sufferer: I just had this problem and in my case (in contrast to OP who tried the same without success) the fix was to revise php.ini, changing

date.timezone = America/New York

to

date.timezone = America/New_York

That is adding the underscore.

I have being trying to avoid typing the passphrase all the time also because i am using ssh on windows. What i did was to modify my .profile file, so that i enter my passphrase one in a particular session. So this is the piece of code:

    SSH_ENV="$HOME/.ssh/environment"

    # start the ssh-agent
    function start_agent {
        echo "Initializing new SSH agent..."
        # spawn ssh-agent
        ssh-agent | sed 's/^echo/#echo/' > "$SSH_ENV"
        echo succeeded
        chmod 600 "$SSH_ENV"
        . "$SSH_ENV" > /dev/null
        ssh-add
    }

    # test for identities
    function test_identities {
        # test whether standard identities have been added to the agent already
        ssh-add -l | grep "The agent has no identities" > /dev/null
        if [ $? -eq 0 ]; then
            ssh-add
            # $SSH_AUTH_SOCK broken so we start a new proper agent
            if [ $? -eq 2 ];then
                start_agent
            fi
        fi
    }

    # check for running ssh-agent with proper $SSH_AGENT_PID
    if [ -n "$SSH_AGENT_PID" ]; then
        ps -fU$USER | grep "$SSH_AGENT_PID" | grep ssh-agent > /dev/null
        if [ $? -eq 0 ]; then
      test_identities
        fi
    # if $SSH_AGENT_PID is not properly set, we might be able to load one from
    # $SSH_ENV
    else
        if [ -f "$SSH_ENV" ]; then
      . "$SSH_ENV" > /dev/null
        fi
        ps -fU$USER | grep "$SSH_AGENT_PID" | grep ssh-agent > /dev/null
        if [ $? -eq 0 ]; then
            test_identities
        else
            start_agent
        fi
    fi

so with this i type my passphrase once in a session..

Winstone is pretty good http://blog.jayway.com/2008/11/28/executable-war-with-winstone-maven-plugin/. But not for complex sites. And that's a shame because all it takes is to include the plugin.

function_that_needs_strings(*my_list) # works!

You can read all about it here.

Using ES6 syntax in React does not bind this to user-defined functions however it will bind this to the component lifecycle methods.

So the function that you declared will not have the same context as the class and trying to access this will not give you what you are expecting.

For getting the context of class you have to bind the context of class to the function or use arrow functions.

Method 1 to bind the context:

class MyContainer extends Component {

    constructor(props) {
        super(props);
        this.onMove = this.onMove.bind(this);
        this.testVarible= "this is a test";
    }

    onMove() {
        console.log(this.testVarible);
    }
}

Method 2 to bind the context:

class MyContainer extends Component {

    constructor(props) {
        super(props);
        this.testVarible= "this is a test";
    }

    onMove = () => {
        console.log(this.testVarible);
    }
}

Method 2 is my preferred way but you are free to choose your own.

Update: You can also create the properties on class without constructor:

class MyContainer extends Component {

    testVarible= "this is a test";

    onMove = () => {
        console.log(this.testVarible);
    }
}

Note If you want to update the view as well, you should use state and setState method when you set or change the value.

Example:

class MyContainer extends Component {

    state = { testVarible: "this is a test" };

    onMove = () => {
        console.log(this.state.testVarible);
        this.setState({ testVarible: "new value" });
    }
}

This can work as well.

if (tabControl.SelectedTab.Text == "tabText" )
{
    .. do stuff
}

Your /home/gnu/bin/c++ seem to require additional flag to link things properly and CMake doesn't know about that.

To use /usr/bin/c++ as your compiler run cmake with -DCMAKE_CXX_COMPILER=/usr/bin/c++.

Also, CMAKE_PREFIX_PATH variable sets destination dir where your project' files should be installed. It has nothing to do with CMake installation prefix and CMake itself already know this.

So far, the accepted answer has worked best for me. However, my concern has always been that there is a likely scenario where I might refactor the notebooks directory into subdirectories, requiring to change the module_path in every notebook. I decided to add a python file within each notebook directory to import the required modules.

Thus, having the following project structure:

project
|__notebooks
   |__explore
      |__ notebook1.ipynb
      |__ notebook2.ipynb
      |__ project_path.py
   |__ explain
       |__notebook1.ipynb
       |__project_path.py
|__lib
   |__ __init__.py
   |__ module.py

I added the file project_path.py in each notebook subdirectory (notebooks/explore and notebooks/explain). This file contains the code for relative imports (from @metakermit):

import sys
import os

module_path = os.path.abspath(os.path.join(os.pardir, os.pardir))
if module_path not in sys.path:
    sys.path.append(module_path)

This way, I just need to do relative imports within the project_path.py file, and not in the notebooks. The notebooks files would then just need to import project_path before importing lib. For example in 0.0-notebook.ipynb:

import project_path
import lib

The caveat here is that reversing the imports would not work. THIS DOES NOT WORK:

import lib
import project_path

Thus care must be taken during imports.

Dictionary<int,string> comboSource = new Dictionary<int,string>();
comboSource.Add(1, "Sunday");
comboSource.Add(2, "Monday");

Aftr adding values to Dictionary, use this as combobox datasource:

comboBox1.DataSource = new BindingSource(comboSource, null);
comboBox1.DisplayMember = "Value";
comboBox1.ValueMember = "Key";

I had the same issue, unable to resize the image when adjusting browser dimensions.

Bad Code:

html {  
  background-color: white;  
  background-image: url("example.png");  
  background-repeat: no-repeat;  
  background-attachment: scroll;  
  background-position: 0% 0%;
}

Good Code:

html {  
  background-color: white;  
  background-image: url("example.png");  
  background-repeat: no-repeat;  
  background-attachment: scroll;  
  background-position: 0% 0%;
  background-size: contain;
}

The key here is the addition of this element -> background-size: contain;

Jquery Ajax will default send the data as query string parameters form like:

RecordId=456&UserId=123

unless the processData option is set to false, in which case it will sent as object to the server.

• contentType option is for the server that in which format client has sent the data.

• dataType option is for the server which tells that what type of data client is expecting back from the server.

Don't specify contentType so that server will parse them as query String parameters not as json.

OR

Use contentType as 'application/json; charset=utf-8' and use JSON.stringify(object) so that server would be able to deserialize json from string.

You cannot "convert" an existing column into an IDENTITY column - you will have to create a new column as INT IDENTITY:

ALTER TABLE ProductInProduct 
ADD NewId INT IDENTITY (1, 1);

Update:

OK, so there is a way of converting an existing column to IDENTITY. If you absolutely need this - check out this response by Martin Smith with all the gory details.

Note that as others have pointed out mysql_real_escape_string() will solve the problem (as will addslashes), however you should always use mysql_real_escape_string() for security reasons - consider:

SELECT * FROM valid_users WHERE username='$user' AND password='$password'

What if the browser sends

user="admin' OR (user=''"
password="') AND ''='"

The query becomes:

SELECT * FROM valid_users 
WHERE username='admin' OR (user='' AND password='') AND ''=''

i.e. the security checks are completely bypassed.

C.

One way to achieve this is to add a DefaultDocument settings in the Web.config.

  <system.webServer>
   <defaultDocument>
    <files>
      <clear />
      <add value="DefaultPage.aspx" />
    </files>
   </defaultDocument>
  </system.webServer>

You can set port in java code:

HashMap<String, Object> props = new HashMap<>();
props.put("server.port", 9999);

new SpringApplicationBuilder()
    .sources(SampleController.class)                
    .properties(props)
    .run(args);

Or in application.yml:

server:
    port: 9999

Or in application.properties:

server.port=9999

Or as a command line parameter:

-Dserver.port=9999

Take a look at ArrayList#addAll(Collection)

Appends all of the elements in the specified collection to the end of this list, in the order that they are returned by the specified collection's Iterator. The behaviour of this operation is undefined if the specified collection is modified while the operation is in progress. (This implies that the behaviour of this call is undefined if the specified collection is this list, and this list is nonempty.)

So basically you could use

ArrayList<String> listOfStrings = new ArrayList<>(list.size());
listOfStrings.addAll(list);

Untested....but should work.

Dim lastrow as long

lastrow = range("D65000").end(xlup).Row

ActiveCell.FormulaR1C1 = _
        "=IF(MONTH(RC[-1])>3,"" ""&YEAR(RC[-1])&""-""&RIGHT(YEAR(RC[-1])+1,2),"" ""&YEAR(RC[-1])-1&""-""&RIGHT(YEAR(RC[-1]),2))"
    Selection.AutoFill Destination:=Range("E2:E" & lastrow)
    'Selection.AutoFill Destination:=Range("E2:E"& lastrow)
    Range("E2:E1344").Select

Only exception being are you sure your Autofill code is perfect...

This is not strictly true as the NTFS filesystem supports paths up to 32k characters. You can use the win32 api and "\\?\" prefix the path to use greater than 260 characters.

A detailed explanation of long path from the .Net BCL team blog.
A small excerpt highlights the issue with long paths

Another concern is inconsistent behavior that would result by exposing long path support. Long paths with the \\?\ prefix can be used in most of the file-related Windows APIs, but not all Windows APIs. For example, LoadLibrary, which maps a module into the address of the calling process, fails if the file name is longer than MAX_PATH. So this means MoveFile will let you move a DLL to a location such that its path is longer than 260 characters, but when you try to load the DLL, it would fail. There are similar examples throughout the Windows APIs; some workarounds exist, but they are on a case-by-case basis.

Let's say you have a Dictionary called fooDictionary

fooDictionary.Values.ToList().IndexOf(someValue);

Values.ToList() converts your dictionary values into a List of someValue objects.

IndexOf(someValue) searches your new List looking for the someValue object in question and returns the Index which would match the index of the Key/Value pair in the dictionary.

This method does not care about the dictionary keys, it simply returns the index of the value that you are looking for.

This does not however account for the issue that there may be several matching "someValue" objects.

Besides these given great answers, What I have learned is that:

NEVER compare objects with == unless you intend to be comparing them by their references.
