Setting "skipLibCheck": true in tsconfig.json solved my problem

"compilerOptions": {
    "skipLibCheck": true
}

Steps:

1. "gulp": "^3.9.1",
2. npm install
3. gulp styles

First, install unzip on colab:

!apt install unzip

then use unzip to extract your files:

!unzip  source.zip -d destination.zip

The answer of Anuja Patil only works with a single file input on a page. This works if there are more than one. This snippet will also show all files if multiple is enabled.

<script type="text/javascript">

    $('.custom-file input').change(function (e) {
        var files = [];
        for (var i = 0; i < $(this)[0].files.length; i++) {
            files.push($(this)[0].files[i].name);
        }
        $(this).next('.custom-file-label').html(files.join(', '));
    });

</script>

Note that $(this).next('.custom-file-label').html($(this)[0].files.join(', ')); does not work. So that is why the for loop is needed.

If you never work with mulitple files in the file upload, this simpler snippet can be used.

<script type="text/javascript">

    $('.custom-file input').change(function (e) {
        if (e.target.files.length) {
            $(this).next('.custom-file-label').html(e.target.files[0].name);
        }
    });

</script>

In my case, upgraded from spring-securiy-web 3.1.3 to 4.2.12, the defaultHttpFirewall was changed from DefaultHttpFirewall to StrictHttpFirewall by default. So just define it in XML configuration like below:

<bean id="defaultHttpFirewall" class="org.springframework.security.web.firewall.DefaultHttpFirewall"/>
<sec:http-firewall ref="defaultHttpFirewall"/>

set HTTPFirewall as DefaultHttpFirewall

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

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

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

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

import numpy as np
import matplotlib.pyplot as plt

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

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

In my case, the issue was of unsupported java version

Check the file /etc/init.d/jenkins to find out which java versions are supported.

To find which java versions are supported, run

grep -m 1 "JAVA_ALLOWED_VERSIONS" /etc/init.d/jenkins

The output will be like this(your's might be different)

JAVA_ALLOWED_VERSIONS=( "1.8" "11" )

In my case version 1.8 and 11 are supported. I will be going with version 11.

Install the supported version of jre using command

For ubuntu/debian

sudo apt install openjdk-11-jre 

For centOS use

sudo yum install java-11-openjdk-devel

Find the path to newly installed jre

For ubuntu/debian path is

/usr/lib/jvm/java-11-openjdk-amd64/bin/java

You can find the path on centOS under /usr/lib/jvm/

Modify the file /etc/init.d/jenkins At line number 28, replace the JAVA=`type -p java` with JAVA='/usr/lib/jvm/java-11-openjdk-amd64/bin/java'

Now run command to reload the systemctl daemon

sudo systemctl daemon-reload

Start the jenkins service

sudo systemctl start jenkins

In postman, set method type to POST.

Then select Body -> form-data -> Enter your parameter name (file according to your code)

and on right side next to value column, there will be dropdown "text, file", select File. choose your image file and post it.

For rest of "text" based parameters, you can post it like normally you do with postman. Just enter parameter name and select "text" from that right side dropdown menu and enter any value for it, hit send button. Your controller method should get called.

Looks like the path you gave doesn't have any bootstrap files in them.

href="~/lib/bootstrap/dist/css/bootstrap.min.css"

Make sure the files exist over there , else point the files to the correct path, which should be in your case

href="~/node_modules/bootstrap/dist/css/bootstrap.min.css"

I have had this issue also, and while -UseBasicParsing will work for some, if you actually need to interact with the dom it wont work. Try using a a group policy to stop the initial configuration window from ever appearing and powershell won't stop you anymore. See here https://wahlnetwork.com/2015/11/17/solving-the-first-launch-configuration-error-with-powershells-invoke-webrequest-cmdlet/

Took me just a few minutes once I found this page, once the GP is set, powershell will allow you through.

Here is a really good way to manage this error. You can put the below line in .eslintrc.js file.

Based on the operating system, it will take appropriate line endings.

rules: {
        'linebreak-style': ['error', process.platform === 'win32' ? 'windows' : 'unix'],
 }

I tried this but it didn't work for me and threw errors:

npm --depth 9999 update 
npm rebuild node-sass

I have installed the latest Node.js (which for the moment is 11.11.0 Current), after facing this problem I just did the following:

1. downgrade to recommended version (which for the moment is 10.15.3 LTS)
   • you can get it from NodeJS,
2. deleted node_modules and
3. then reinstall yarn:

     yarn install
     yarn start

After executing these commands everything is working fine for me.

I'm triggering my notifications from FCM console and through HTTP/JSON ... with the same result.

I can handle the title, full message, but the icon is always a default white circle:

Notification screenshot

Instead of my custom icon in the code (setSmallIcon or setSmallIcon) or default icon from the app:

 Intent intent = new Intent(this, MainActivity.class);
    // use System.currentTimeMillis() to have a unique ID for the pending intent
    PendingIntent pIntent = PendingIntent.getActivity(this, (int) System.currentTimeMillis(), intent, 0);

    if (Build.VERSION.SDK_INT < 16) {
        Notification n  = new Notification.Builder(this)
                .setContentTitle(messageTitle)
                .setContentText(messageBody)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentIntent(pIntent)
                .setAutoCancel(true).getNotification();
        NotificationManager notificationManager =
                (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        //notificationManager.notify(0, n);
        notificationManager.notify(id, n);
    } else {
        Bitmap bm = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);

        Notification n  = new Notification.Builder(this)
                .setContentTitle(messageTitle)
                .setContentText(messageBody)
                .setSmallIcon(R.drawable.ic_stat_ic_notification)
                .setLargeIcon(bm)
                .setContentIntent(pIntent)
                .setAutoCancel(true).build();

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        //notificationManager.notify(0, n);
        notificationManager.notify(id, n);
    }

I cannot claim to be very knowledgeable on this but I had the same problem and have resolved it.

There is a 7th way to resolve this, by using an async function.

Write your function but add the prefix async.

By doing this Gulp wraps the function in a promise, and the task will run without errors.

Example:

async function() {
  // do something
};

Resources:

1. Last section on the Gulp page Async Completion: Using async/await.

2. Mozilla async functions docs.

Not sure when this changed, but with the latest version of typescript, you just need to use import moment from 'moment'; and everything else should work as normal.

UPDATE:

Looks like moment recent fixed their import. As of at least 2.24.0 you'll want to use import * as moment from 'moment';

On top of mentioning your environment variable for HADOOP_HOME in windows as C:\winutils, you also need to make sure you are the administrator of the machine. If not and adding environment variables prompts you for admin credentials (even under USER variables) then these variables will be applicable once you start your command prompt as administrator.

I had exactly the same problem, but in an Angular2 app, and this article just solve it: https://medium.com/@s_eschweiler/using-external-libraries-with-angular-2-87e06db8e5d1#.p6gra5eli

Summary of the article:

1. Installing the Library npm install lodash --save
2. Add TypeScript Definitions for Lodash tsd install underscore
3. Including Script <script src="node_modules/lodash/index.js"></script>
4. Configuring SystemJS System.config({ paths: { lodash: './node_modules/lodash/index.js'
5. Importing Module import * as _ from ‘lodash’;

I hope it can be useful for your case too

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

A nicer option is to make the display of console.log and debugger statements conditional based on the node environment.

  rules: {
    // allow console and debugger in development
    'no-console': process.env.NODE_ENV === 'production' ? 2 : 0,
    'no-debugger': process.env.NODE_ENV === 'production' ? 2 : 0,
  },

I had the same problem on my new Windows 10 machine. I had to intall the Windows build tools with npm install -g windows-build-tools. (https://github.com/Microsoft/nodejs-guidelines/blob/master/windows-environment.md#environment-setup-and-configuration)

BUILD SUCCESSFUL (total time: 2 seconds)

simple

COPY README.md  package.json gulpfile.js __BUILD_NUMBER ./

from the doc

If multiple resources are specified, either directly or due to the use of a wildcard, then must be a directory, and it must end with a slash /.

With the directory parameter:

impdp system/password@$ORACLE_SID schemas=USER_SCHEMA directory=MY_DIR \
  dumpfile=mydumpfile.dmp logfile=impdpmydumpfile.log

The default directory is DATA_PUMP_DIR, which is presumably set to /u01/app/oracle/admin/mydatabase/dpdump on your system.

To use a different directory you (or your DBA) will have to create a new directory object in the database, which points to the Oracle-visible operating system directory you put the file into, and assign privileges to the user doing the import.

you may also want to npm remove gulp-sass and re-install gulp-sass if you've switched node versions.

I have created step by step instructions on how to do this as I also was very confused about how to get this working.

How to make a self extracting archive that runs your setup.exe with 7zip -sfx switch

Here are the steps.

Step 1 - Setup your installation folder

To make this easy create a folder c:\Install. This is where we will copy all the required files.

Step 2 - 7Zip your installers

1. Go to the folder that has your .msi and your setup.exe
2. Select both the .msi and the setup.exe
3. Right-Click and choose 7Zip --> "Add to Archive"
4. Name your archive "Installer.7z" (or a name of your choice)
5. Click Ok
6. You should now have "Installer.7z".
7. Copy this .7z file to your c:\Install directory

Step 3 - Get the 7z-Extra sfx extension module

You need to download 7zSD.sfx

1. Download one of the LZMA packages from here
2. Extract the package and find 7zSD.sfx in the bin folder.
3. Copy the file "7zSD.sfx" to c:\Install

Step 4 - Setup your config.txt

I would recommend using NotePad++ to edit this text file as you will need to encode in UTF-8, the following instructions are using notepad++.

1. Using windows explorer go to c:\Install
2. right-click and choose "New Text File" and name it config.txt
3. right-click and choose "Edit with NotePad++
4. Click the "Encoding Menu" and choose "Encode in UTF-8"

5. Enter something like this:

   ;!@Install@!UTF-8!
   Title="SOFTWARE v1.0.0.0"
   BeginPrompt="Do you want to install SOFTWARE v1.0.0.0?"
   RunProgram="setup.exe"
   ;!@InstallEnd@!
   

Edit this replacing [SOFTWARE v1.0.0.0] with your product name. Notes on the parameters and options for the setup file are here.

CheckPoint

You should now have a folder "c:\Install" with the following 3 files:

1. Installer.7z
2. 7zSD.sfx
3. config.txt

Step 5 - Create the archive

These instructions I found on the web but nowhere did it explain any of the 4 steps above.

1. Open a cmd window, Window + R --> cmd --> press enter

2. In the command window type the following

   cd \
   cd Install
   copy /b 7zSD.sfx + config.txt + Installer.7z MyInstaller.exe
   

3. Look in c:\Install and you will now see you have a MyInstaller.exe

You are finished

Run the installer

Double click on MyInstaller.exe and it will prompt with your message. Click OK and the setup.exe will run.

P.S. Note on Automation

Now that you have this working in your c:\Install directory I would create an "Install.bat" file and put the copy script in it.

copy /b 7zSD.sfx + config.txt + Installer.7z MyInstaller.exe

Now you can just edit and run the Install.bat every time you need to rebuild a new version of you deployment package.

for listener support no services you can use the following command to set local_listener paramter in your spfile use your listener port and server ip address

alter system set local_listener='(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.101)(PORT=1520)))' sid='testdb' scope=spfile;

1. When you've installed gulp global, you need to go to

   C:\nodejs\node_modules\npm\npm

2. There you do

   SHIFT + Right Click

3. Choose "Open command prompt here"

4. Run gulp from that cmd window

In my case, the file containing JSON string had BOM. Once I removed BOM the problem was solved.

var isProduction = (process.argv.indexOf("production")>-1);

CLI gulp production calls my production task and sets a flag for any conditionals.

You need a ResourceLink in your META-INF/context.xml file to make the global resource available to the web application.

 <ResourceLink name="jdbc/mydb"
             global="jdbc/mydb"
              type="javax.sql.DataSource" />

Personally, I have create a file.sh (right 755) in the root directory, file who do this job, on order of the crontab.

Crontab code:

10 2 * * * root /root/backupautomatique.sh

File.sh code:

rm -f /home/mordb-148-251-89-66.sql.gz #(To erase the old one)

mysqldump mor | gzip > /home/mordb-148-251-89-66.sql.gz (what you have done)

scp -P2222 /home/mordb-148-251-89-66.sql.gz root@otherip:/home/mordbexternes/mordb-148-251-89-66.sql.gz

(to send a copy somewhere else if the sending server crashes, because too old, like me ;-))

you need /q at the end

MsiExec.exe /x {2F808931-D235-4FC7-90CD-F8A890C97B2F} /q

You should install these as devDependencies:
- gulp-util
- gulp-load-plugins

Then, you can use them either this way:

var plugins     = require('gulp-load-plugins')();
Use gulp-util as : plugins.util()

or this:

var util = require('gulp-util')

this.donorsTableAdapter.Fill(this.sbmsDataSet.donors);

For me the following worked: Change permission into 'read only' for 'everyone' to the file /Applications/XAMPP/xamppfiles/etc/my.cnf. Then start MySQL from XAMPP manager.

heap space errors generally occur due to either bringing too much data back to the driver or the executor. In your code it does not seem like you are bringing anything back to the driver, but instead you maybe overloading the executors that are mapping an input record/row to another using the threeDReconstruction() method. I am not sure what is in the method definition but that is definitely causing this overloading of the executor. Now you have 2 options,

1. edit your code to do the 3-D reconstruction in a more efficient manner.
2. do no edit code, but give more memory to your executors, as well as give more memory-overhead. [spark.executor.memory or spark.driver.memoryOverhead]

I would advise being careful with the increase and use only as much as you need. Each job is unique in terms of its memory requirements, so I would advise empirically trying different values increasing every time by a power of 2 (256M,512M,1G .. and so on)

You will arrive at a value for the executor memory that will work. Try re-running the job with this value 3 or 5 times before settling for this configuration.

right click somewhere on the file or in project explorer and choose 'run as'->'java application'

I had the same issue when I changed the home directory of one use. In my case it was because of selinux. I used the below to fix the issue:

selinuxenabled 0
setenforce 0

I my case I'd manually moved a .war file to /var/lib/tomcat9/webapps and unzipped it, then did "chown -R tomcat:tomcat *" in that directory and it resolved it.

Here is a solution which needed ctypes module only. Support pyinstaller wrapped program.

#!python
# coding: utf-8
import sys
import ctypes

def run_as_admin(argv=None, debug=False):
    shell32 = ctypes.windll.shell32
    if argv is None and shell32.IsUserAnAdmin():
        return True

    if argv is None:
        argv = sys.argv
    if hasattr(sys, '_MEIPASS'):
        # Support pyinstaller wrapped program.
        arguments = map(unicode, argv[1:])
    else:
        arguments = map(unicode, argv)
    argument_line = u' '.join(arguments)
    executable = unicode(sys.executable)
    if debug:
        print 'Command line: ', executable, argument_line
    ret = shell32.ShellExecuteW(None, u"runas", executable, argument_line, None, 1)
    if int(ret) <= 32:
        return False
    return None


if __name__ == '__main__':
    ret = run_as_admin()
    if ret is True:
        print 'I have admin privilege.'
        raw_input('Press ENTER to exit.')
    elif ret is None:
        print 'I am elevating to admin privilege.'
        raw_input('Press ENTER to exit.')
    else:
        print 'Error(ret=%d): cannot elevate privilege.' % (ret, )

You are trying to link objects compiled by different versions of the compiler. That's not supported in modern versions of VS, at least not if you are using the C++ standard library. Different versions of the standard library are binary incompatible and so you need all the inputs to the linker to be compiled with the same version. Make sure you re-compile all the objects that are to be linked.

The compiler error names the objects involved so the information the the question already has the answer you are looking for. Specifically it seems that the static library that you are linking needs to be re-compiled.

So the solution is to recompile Projectname1.lib with VS2012.

I was also facing the same error. The reason for this is that there is no smtp server on your environment. For creating a fake smtp server I used this fake-smtp.jar file for creating a virtual server and listening to all the requests. If you are facing the same error, I recommend you to use this jar and run it after extracting and then try to run your application.

Download latest version of fake smtp

Open with append:

pFile2 = fopen("myfile2.txt", "a");

then just write to pFile2, no need to fseek().

In theory, yes, it's just a matter of plugging things in. Zipfile can give you a file-like object for a file in a zip archive, and image.load will accept a file-like object. So something like this should work:

import zipfile
archive = zipfile.ZipFile('images.zip', 'r')
imgfile = archive.open('img_01.png')
try:
    image = pygame.image.load(imgfile, 'img_01.png')
finally:
    imgfile.close()

NullPointerException with JSP can also happen if:

A getter returns a non-public inner class.

This code will fail if you remove Getters's access modifier or make it private or protected.

JAVA:

package com.myPackage;
public class MyClass{ 
    //: Must be public or you will get:
    //: org.apache.jasper.JasperException: 
    //: java.lang.NullPointerException
    public class Getters{
        public String 
        myProperty(){ return(my_property); }
    };;

    //: JSP EL can only access functions:
    private Getters _get;
    public  Getters  get(){ return _get; }

    private String 
    my_property;

    public MyClass(String my_property){
        super();
        this.my_property    = my_property;
        _get = new Getters();
    };;
};;

JSP

<%@ taglib uri   ="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page import="com.myPackage.MyClass" %>
<%
    MyClass inst = new MyClass("[PROP_VALUE]");
    pageContext.setAttribute("my_inst", inst ); 
%><html lang="en"><body>
    ${ my_inst.get().myProperty() }
</body></html>

From the JIRA knowledge base:

Symptoms

Workflow actions may be inaccessible

1. JIRA may throw exceptions on screen
2. One or both of the following conditions may exist:

The following appears in the atlassian-jira.log:

     2007-12-06 10:55:05,327 http-8080-Processor20 ERROR [500ErrorPage] 
     Exception caught in500 page Unable to compile class for JSP
    org.apache.jasper.JasperException: Unable to compile class for JSP
   at org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:572)
   at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:305)

_

Cause:

The Tomcat container caches .java and .class files generated by the JSP parser they are used by the web application. Sometimes these get corrupted or cannot be found. This may occur after a patch or upgrade that contains modifications to JSPs.

Resolution

1.Delete the contents of the /work folder if using standalone JIRA or /work if using EAR/WAR installation . 2. Verify the user running the JIRA application process has Read/Write permission to the /work directory. 3. Restart the JIRA application container to rebuild the files.

For "zip" files, you can use import zipfile and your code will be working simply with these lines:

import zipfile
import pandas as pd
with zipfile.ZipFile("Crime_Incidents_in_2013.zip") as z:
   with z.open("Crime_Incidents_in_2013.csv") as f:
      train = pd.read_csv(f, header=0, delimiter="\t")

put .gitignore in your main catalog

git status (you will see which files you can commit)
git add -A
git commit -m "message"
git push

Try this, it will insert the list item at index 0;

DropDownList1.Items.Insert(0, new ListItem("Add New", ""));

In Windows machine, please follows the preceding steps.

1. Open file in notepad.
2. Click on Save as
3. Select Encoding type UTF-8.

Now source your db.

fileinput already supports inplace editing. It redirects stdout to the file in this case:

#!/usr/bin/env python3
import fileinput

with fileinput.FileInput(filename, inplace=True, backup='.bak') as file:
    for line in file:
        print(line.replace(text_to_search, replacement_text), end='')

I think the easiest is to simply open the file in write mode and then close it. For example, if your file myfile.dat contains:

"This is the original content"

Then you can simply write:

f = open('myfile.dat', 'w')
f.close()

This would erase all the content. Then you can write the new content to the file:

f = open('myfile.dat', 'w')
f.write('This is the new content!')
f.close()

Here's what actually worked for me, after guidance from answers here:

export BASH_VARIABLE="[1,2,3]"
curl http://localhost:8080/path -d "$(cat <<EOF
{
  "name": $BASH_VARIABLE,
  "something": [
    "value1",
    "value2",
    "value3"
  ]
}
EOF
)" -H 'Content-Type: application/json'

One of my experience:

I always change the default keyboard shortcut of Chrome through reverse engineering. After modification, I forgot to close Chrome and ran the following:

sudo cp chrome /opt/google/chrome/chrome
cp: cannot create regular file '/opt/google/chrome/chrome': Text file busy

Using strace, you can find the more details:

sudo strace cp ./chrome /opt/google/chrome/chrome 2>&1 |grep 'Text file busy'
open("/opt/google/chrome/chrome", O_WRONLY|O_TRUNC) = -1 ETXTBSY (Text file busy)

I know this is an old thread, but I just cannot steer away from posting some useful info on this. I see the Zip question come up a lot and this answers nearlly most of the common questions.

To get around framework issues of using 4.5+... Their is a ZipStorer class created by jaime-olivares: https://github.com/jaime-olivares/zipstorer, he also has added an example of how to use this class as well and has also added an example of how to search for a specific filename as well.

And for reference on how to use this and iterate through for a certain file extension as example you could do this:

#region
/// <summary>
/// Custom Method - Check if 'string' has '.png' or '.PNG' extension.
/// </summary>
static bool HasPNGExtension(string filename)
{
    return Path.GetExtension(filename).Equals(".png", StringComparison.InvariantCultureIgnoreCase)
        || Path.GetExtension(filename).Equals(".PNG", StringComparison.InvariantCultureIgnoreCase);
}
#endregion

private void button1_Click(object sender, EventArgs e)
{
    //NOTE: I recommend you add path checking first here, added the below as example ONLY.
    string ZIPfileLocationHere = @"C:\Users\Name\Desktop\test.zip";
    string EXTRACTIONLocationHere = @"C:\Users\Name\Desktop";

    //Opens existing zip file.
    ZipStorer zip = ZipStorer.Open(ZIPfileLocationHere, FileAccess.Read);

    //Read all directory contents.
    List<ZipStorer.ZipFileEntry> dir = zip.ReadCentralDir();

    foreach (ZipStorer.ZipFileEntry entry in dir)
    {
        try
        {
            //If the files in the zip are "*.png or *.PNG" extract them.
            string path = Path.Combine(EXTRACTIONLocationHere, (entry.FilenameInZip));
            if (HasPNGExtension(path))
            {
                //Extract the file.
                zip.ExtractFile(entry, path);
            }
        }
        catch (InvalidDataException)
        {
            MessageBox.Show("Error: The ZIP file is invalid or corrupted");
            continue;
        }
        catch
        {
            MessageBox.Show("Error: An unknown error ocurred while processing the ZIP file.");
            continue;
        }
    }
    zip.Close();
}

If you use Eclipse as your IDE I would recommend the excellent eclipse plugin memory analyzer

Another option is to use JVisualVM, it can read (and create) heap dumps as well, and is shipped with every JDK. You can find it in the bin directory of your JDK.

subprocess.check_output(...)

calls the process, raises if its error code is nonzero, and otherwise returns its stdout. It's just a quick shorthand so you don't have to worry about PIPEs and things.

$zip = new ZipArchive;
$tmp_file = 'assets/myzip.zip';
    if ($zip->open($tmp_file,  ZipArchive::CREATE)) {
        $zip->addFile('folder/bootstrap.js', 'bootstrap.js');
        $zip->addFile('folder/bootstrap.min.js', 'bootstrap.min.js');
        $zip->close();
        echo 'Archive created!';
        header('Content-disposition: attachment; filename=files.zip');
        header('Content-type: application/zip');
        readfile($tmp_file);
   } else {
       echo 'Failed!';
   }

This worked for me but only after forcing the specific verbs to be handled by the default handler.

<system.web>
...
  <httpHandlers>
  ... 
    <add path="*" verb="OPTIONS" type="System.Web.DefaultHttpHandler" validate="true"/>
    <add path="*" verb="TRACE" type="System.Web.DefaultHttpHandler" validate="true"/>
    <add path="*" verb="HEAD" type="System.Web.DefaultHttpHandler" validate="true"/>

You still use the same configuration as you have above, but also force the verbs to be handled with the default handler and validated. Source: http://forums.asp.net/t/1311323.aspx

An easy way to test is just to deny GET and see if your site loads.

For installing pip with get-pip.py behind a proxy I went with the steps below. My server was even behind a jump server.

From the jump server:

ssh -R 18080:proxy-server:8080 my-python-server

On the "python-server"

export https_proxy=https://localhost:18080 ; export http_proxy=http://localhost:18080 ; export ftp_proxy=$http_proxy
python get-pip.py

Success.

For zooming your map two level then just add this small code of line map.setZoom(map.getZoom() + 2);

Is there any advantage in creating a temporary file in a more careful way

The temporary files are usually created in the temporary directory (such as /tmp) where all other users and processes has read and write access (any other script can create the new files there). Therefore the script should be careful about creating the files such as using with the right permissions (e.g. read only for the owner, see: help umask) and filename should be be not easily guessed (ideally random). Otherwise if the filenames aren't unique, it can create conflict with the same script ran multiple times (e.g. race condition) or some attacker could either hijack some sensitive information (e.g. when permissions are too open and filename is easy to guess) or create/replacing the file with their own version of the code (like replacing the commands or SQL queries depending on what is being stored).

You could use the following approach to create the temporary directory:

TMPDIR=".${0##*/}-$$" && mkdir -v "$TMPDIR"

or temporary file:

TMPFILE=".${0##*/}-$$" && touch "$TMPFILE"

However it is still predictable and not considered safe.

As per man mktemp, we can read:

Traditionally, many shell scripts take the name of the program with the pid as a suffix and use that as a temporary file name. This kind of naming scheme is predictable and the race condition it creates is easy for an attacker to win.

So to be safe, it is recommended to use mktemp command to create unique temporary file or directory (-d).

    I changed 
    Order Deny,Allow
    Deny From All      in .htaccess to   " Require all denied "    and restarted apache but it did not help.

Path for apache2.conf in ubuntu is /etc/apache2/apache.conf

Then I added following lines in apache2.conf and then my folder is working fine

    <Directory /path of required folder>
            Options Indexes FollowSymLinks
            AllowOverride All
            Require all granted
       </Directory>

   and run  " Sudo service apache2 restart " 

1. Create a table with Identity column + other columns;
2. Create a view over it and expose only the columns you will bulk insert;
3. BCP in the view

XAMPP does not have a pre build console to run php or mysql commands, so, you have to add to windows PATH environment variables, these 2: ;C:\xampp\mysql\bin;C:\xampp\php;

Then you should be able to execute php and mysql commands from the CMD.

UPDATE

I tested it, and it works.

This is how I managed to do what I was trying to do:

[Test]
public void TransferHandlesDisconnect()
{
    // ... set up config here
    var methodTester = new Mock<Transfer>(configInfo);
    methodTester.CallBase = true;
    methodTester
        .Setup(m => 
            m.GetFile(
                It.IsAny<IFileConnection>(), 
                It.IsAny<string>(), 
                It.IsAny<string>()
            ))
        .Throws<System.IO.IOException>();

    methodTester.Object.TransferFiles("foo1", "foo2");
    Assert.IsTrue(methodTester.Object.Status == TransferStatus.TransferInterrupted);
}

If there is a problem with this method, I would like to know; the other answers suggest I am doing this wrong, but this was exactly what I was trying to do.

I solved this issue for myself, I found there's was two files of http-client with different version of other dependent jar files. So there may version were collapsing between libraries files so remove all old/previous libraries files and re-add are jar files from lib folder of this zip file:

Donwload Zip file from here

I've compared performance (space and time) for a number of ways to store numpy arrays. Few of them support multiple arrays per file, but perhaps it's useful anyway.

Npy and binary files are both really fast and small for dense data. If the data is sparse or very structured, you might want to use npz with compression, which'll save a lot of space but cost some load time.

If portability is an issue, binary is better than npy. If human readability is important, then you'll have to sacrifice a lot of performance, but it can be achieved fairly well using csv (which is also very portable of course).

More details and the code are available at the github repo.

Finally, I've defeated my CiSCO EAP-FAST corporate wifi network, and all our Android devices are now able to connect to it.

The walk-around I've performed in order to gain access to this kind of networks from an Android device are easiest than you can imagine.

There's a Wifi Config Editor in the Google Play Store you can use to "activate" the secondary CISCO Protocols when you are setting up a EAP wifi connection.

Its name is Wifi Config Advanced Editor.

• First, you have to setup your wireless network manually as close as you can to your "official" corporate wifi parameters.

• Save it.

• Go to the WCE and edit the parameters of the network you have created in the previous step.

• There are 3 or 4 series of settings you should activate in order to force the Android device to use them as a way to connect (the main site I think you want to visit is Enterprise Configuration, but don't forget to check all the parameters to change them if needed.
  As a suggestion, even if you have a WPA2 EAP-FAST Cipher, try LEAP in your setup. It worked for me as a charm.

• When you finished to edit the config, go to the main Android wifi controller, and force to connect to this network.

• Do not Edit the network again with the Android wifi interface.

I have tested it on Samsung Galaxy 1 and 2, Note mobile devices, and on a Lenovo Thinkpad Tablet.

the first time when you are returning your form make sure you pass the model attribute the form requires which can be done by adding the below code

@RequestMapping(value = "/login", method = RequestMethod.GET)
public String login(Login login)
    return "test";
}

By default the model attribute name is taken as Bean class's name with first lowercase letter

By doing this the form which expects a backing object naming "login" will be made available to it

after the form is submitted you can do the validation by passing your bean object and bindingresult as the method parameters as shown below

@RequestMapping(value = "/login", method = RequestMethod.POST)
public String login(    @ModelAttribute("login") Login login,
                        BindingResult result) 

The solution that worked for me was to edit the registry key to enable long path behaviour, setting the value to 1. This is a new opt-in feature for Windows 10

HKLM\SYSTEM\CurrentControlSet\Control\FileSystem LongPathsEnabled (Type: REG_DWORD)

I got this solution from a named section of the article that @james-hill posted.

https://docs.microsoft.com/windows/desktop/FileIO/naming-a-file#maximum-path-length-limitation

I solved the same problem. I've just added JSTL-1.2.jar to /apache-tomcat-x.x.x/lib and set scope to provided in maven pom.xml:

 <dependency>
     <groupId>jstl</groupId>
     <artifactId>jstl</artifactId>
     <version>1.2</version>
     <scope>provided</scope>
 </dependency>

I believe the id accessors don't match the bean naming conventions and that's why the exception is thrown. They should be as follows:

public Integer getId() { return id; }    
public void setId(Integer i){ id= i; }

You can use this method.

    public static File getRobotCacheFile(Context context) throws IOException {
        File cacheFile = new File(context.getCacheDir(), "robot.png");
        try {
            InputStream inputStream = context.getAssets().open("robot.png");
            try {
                FileOutputStream outputStream = new FileOutputStream(cacheFile);
                try {
                    byte[] buf = new byte[1024];
                    int len;
                    while ((len = inputStream.read(buf)) > 0) {
                        outputStream.write(buf, 0, len);
                    }
                } finally {
                    outputStream.close();
                }
            } finally {
                inputStream.close();
            }
        } catch (IOException e) {
            throw new IOException("Could not open robot png", e);
        }
        return cacheFile;
    }

You should never use InputStream.available() in such cases. It returns only bytes that are buffered. Method with .available() will never work with bigger files and will not work on some devices at all.

In Kotlin (;D):

@Throws(IOException::class)
fun getRobotCacheFile(context: Context): File = File(context.cacheDir, "robot.png")
    .also {
        it.outputStream().use { cache -> context.assets.open("robot.png").use { it.copyTo(cache) } }
    }

You will have to submit this data to the server somehow. I'm assuming that you don't want to do a full page reload every time a user clicks a link, so you'll have to user XHR (AJAX). If you are not using jQuery (or some other JS library) you can read this tutorial on how to do the XHR request "by hand".

Except for that I can't think of any reason for this error.

If you're working from some network that requires you to use a proxy in your browser to connect to the internet (likely an office building), that might be it. I had the same issue and adding the proxy configs to the network settings solved it.

• Go to your preferences (Eclipse -> Preferences on a Mac, or Window -> Preferences on a Windows)
• Then -> General -> expand to view the list underneath -> Select Network Connections (don't expand)
• At the top of the page that appears there is a drop down, select "Manual."
• Then select "HTTP" in the list directly below the drop down (which now should have all it's options checked) and then click the "Edit" button to the right of the list.
• Enter in the proxy url and port you need to connect to the internet in your web browser normally.
• Repeat for "HTTPS."

If you don't know the proxy url and port, talk to your network admin.

Use PtrSafe and see how that works on Excel 2010.

There is a much simpler way. This does not care if it is binary or text file.

Use noskipws.

char buf[SZ];
ifstream f("file");
int i;
for(i=0; f >> noskipws >> buffer[i]; i++);
ofstream f2("writeto");
for(int j=0; j < i; j++) f2 << noskipws << buffer[j];

Or you can just use string instead of the buffer.

string s; char c;
ifstream f("image.jpg");
while(f >> noskipws >> c) s += c;
ofstream f2("copy.jpg");
f2 << s;

normally stream skips white space characters like space or new line, tab and all other control characters. But noskipws makes all the characters transferred. So this will not only copy a text file but also a binary file. And stream uses buffer internally, I assume the speed won't be slow.

// This code was tested by me (Helio Barbosa)

    // this directory (../backup) is for try only.
    // it is necessary create it and put files into him.

    $hDir = '../backup';
    if ($handle = opendir( $hDir )) {
        echo "Manipulador de diretório: $handle\n";
        echo "Arquivos:\n";

        /* Esta é a forma correta de varrer o diretório */
        /* Here is the correct form to do find files into the directory */
        while (false !== ($file = readdir($handle))) {
            // echo($file . "</br>");
            $filepath = $hDir . "/" . $file ;
            // echo( $filepath . "</br>" );
            if(is_file($filepath))
            {
                echo("Deleting:" . $file . "</br>");
                unlink($filepath);
            }           
        }

        closedir($handle);
    }

Resolved similar problem in IBM RAD 7.5 by selecting:

Another approach (especially useful if you need to make a decision to exclude a field at runtime) is to register a TypeAdapter with your gson instance. Example below:

Gson gson = new GsonBuilder()
.registerTypeAdapter(BloodPressurePost.class, new BloodPressurePostSerializer())

In the case below, the server would expect one of two values but since they were both ints then gson would serialize them both. My goal was to omit any value that is zero (or less) from the json that is posted to the server.

public class BloodPressurePostSerializer implements JsonSerializer<BloodPressurePost> {

    @Override
    public JsonElement serialize(BloodPressurePost src, Type typeOfSrc, JsonSerializationContext context) {
        final JsonObject jsonObject = new JsonObject();

        if (src.systolic > 0) {
            jsonObject.addProperty("systolic", src.systolic);
        }

        if (src.diastolic > 0) {
            jsonObject.addProperty("diastolic", src.diastolic);
        }

        jsonObject.addProperty("units", src.units);

        return jsonObject;
    }
}

My favorite one-liner for this is

cd $(mktemp -d)

test open the termenal or cmd. go to the [tomcat-home]\bin directory. ex: c:\tomcat8\bin write the following command: Tomcat8W //ES//Tomcat8 will open dialog, select the java tap(top tap). change the Java virtual Machine value.

Simple solution:

<?php 
exec('wget http://someurl/file.zip');

I have something like this :

public static boolean deleteDirectory(File directory) {
    if(directory.exists()){
        File[] files = directory.listFiles();
        if(null!=files){
            for(int i=0; i<files.length; i++) {
                if(files[i].isDirectory()) {
                    deleteDirectory(files[i]);
                }
                else {
                    files[i].delete();
                }
            }
        }
    }
    return(directory.delete());
}

You can also import only ZipFile:

from zipfile import ZipFile
zf = ZipFile('path_to_file/file.zip', 'r')
zf.extractall('path_to_extract_folder')
zf.close()

Works in Python 2 and Python 3.

This is what I typically do:

File outputDir = context.getCacheDir(); // context being the Activity pointer
File outputFile = File.createTempFile("prefix", "extension", outputDir);

As for their deletion, I am not complete sure either. Since I use this in my implementation of a cache, I manually delete the oldest files till the cache directory size comes down to my preset value.

Since strptime returns a datetime object which has tzinfo attribute, We can simply replace it with desired timezone.

>>> import datetime

>>> date_time_str = '2018-06-29 08:15:27.243860'
>>> date_time_obj = datetime.datetime.strptime(date_time_str, '%Y-%m-%d %H:%M:%S.%f').replace(tzinfo=datetime.timezone.utc)
>>> date_time_obj.tzname()
'UTC'

If you are using svn with Jenkins on a Windows Server, you must accept https certificate using the same Jenkins's Windows service user.
So , if your Jenkins service runs as "MYSERVER\Administrator", you must use this command before all others, only one time of course :

runas /user:MYSERVER\Administrator "svn --username user --password password list https://myserver/svn/REPO "

svn asks you to accept the certificate and stores it in the right path.

After this you'll be able to use svn in jenkins job directly in a Windows batch command step.

Use the \ character to escape a character that has special meaning inside a regular expression.

To automate it, you could use this:

function escapeRegExp(text) {
  return text.replace(/[-[\]{}()*+?.,\\^$|#\s]/g, '\\$&');
}

Update: There is now a proposal to standardize this method, possibly in ES2016: https://github.com/benjamingr/RegExp.escape

Update: The abovementioned proposal was rejected, so keep implementing this yourself if you need it.

I used CRAN package "downloader" found at http://cran.r-project.org/web/packages/downloader/index.html . Much easier.

download(url, dest="dataset.zip", mode="wb") 
unzip ("dataset.zip", exdir = "./")

To be specific, if you want to merge something to master, you can follow the below steps.

git add --all // If you want to stage all changes other options also available
git commit -m "Your commit message"
git push // By default when it clone is sets your origin to master or you would have set sometime with git push -u origin master.

It's a common practice in the pull request model create to a new local branch and then push that branch to remote. For that you need to mention where you want to push your changes at remote. You can do this by mentioning remote at the time of push.

git push origin develop // It will create a remote branch with name "develop".

If you want to create a branch other than your local branch name you can do that with the following command.

git push origin develop:some-other-name

It can be caused by a classpath contamination. Check that you /WEB-INF/lib doesn't contain something like jsp-api-*.jar.

Hmmm -- since this is handled by the JVM, I delved into the OpenJDK VM source code a little bit, thinking that maybe what's done by OpenJDK mimics what's done by Java 6 and prior. It isn't reassuring that there's a way to do this other than on Windows.

On Windows, OpenJDK's get_temp_directory() function makes a Win32 API call to GetTempPath(); this is how on Windows, Java reflects the value of the TMP environment variable.

On Linux and Solaris, the same get_temp_directory() functions return a static value of /tmp/.

I don't know if the actual JDK6 follows these exact conventions, but by the behavior on each of the listed platforms, it seems like they do.

I got the same error by using response.getWriter() before a request.getRequestDispatcher(path).forward(request, response);. So start works fine when I replace it by response.getOutputStream()

Try using SQLITE_STATIC instead of SQLITE_TRANSIENT for those inserts.

SQLITE_TRANSIENT will cause SQLite to copy the string data before returning.

SQLITE_STATIC tells it that the memory address you gave it will be valid until the query has been performed (which in this loop is always the case). This will save you several allocate, copy and deallocate operations per loop. Possibly a large improvement.

Instead of the option a use option x, this will create the directories but only for extraction, not compression.

The accepted answer by Kev to this question doesn't actually give any code, it just points to other resources that I don't have access to. So here's my best attempt at the function. It actually checks that the permission it's looking at is a "Write" permission and that the current user belongs to the appropriate group.

It might not be complete with regard to network paths or whatever, but it's good enough for my purpose, checking local configuration files under "Program Files" for writability:

using System.Security.Principal;
using System.Security.AccessControl;

private static bool HasWritePermission(string FilePath)
{
    try
    {
        FileSystemSecurity security;
        if (File.Exists(FilePath))
        {
            security = File.GetAccessControl(FilePath);
        }
        else
        {
            security = Directory.GetAccessControl(Path.GetDirectoryName(FilePath));
        }
        var rules = security.GetAccessRules(true, true, typeof(NTAccount));

        var currentuser = new WindowsPrincipal(WindowsIdentity.GetCurrent());
        bool result = false;
        foreach (FileSystemAccessRule rule in rules)
        {
            if (0 == (rule.FileSystemRights &
                (FileSystemRights.WriteData | FileSystemRights.Write)))
            {
                continue;
            }

            if (rule.IdentityReference.Value.StartsWith("S-1-"))
            {
                var sid = new SecurityIdentifier(rule.IdentityReference.Value);
                if (!currentuser.IsInRole(sid))
                {
                    continue;
                }
            }
            else
            {
                if (!currentuser.IsInRole(rule.IdentityReference.Value))
                {
                    continue;
                }
            }

            if (rule.AccessControlType == AccessControlType.Deny)
                return false;
            if (rule.AccessControlType == AccessControlType.Allow)
                result = true;
        }
        return result;
    }
    catch
    {
        return false;
    }
}

Open the sql file and comment out the line that tries to create the existing database.

Combining other answers, why not use the ms timestamp with a random value appended; repeat until no conflict, which in practice will be almost never.

For example: File-ccyymmdd-hhmmss-mmm-rrrrrr.txt

Put this in your .vimrc configuration file.

set nobackup

This seems to work fine for me: it checks for file existance and creates the file to be sure it's a writable location. Should work fine, you can change it to return directly the FileStream (which is normally what you need for a temp file):

private string GetTempFile(string fileExtension)
{
  string temp = System.IO.Path.GetTempPath();
  string res = string.Empty;
  while (true) {
    res = string.Format("{0}.{1}", Guid.NewGuid().ToString(), fileExtension);
    res = System.IO.Path.Combine(temp, res);
    if (!System.IO.File.Exists(res)) {
      try {
        System.IO.FileStream s = System.IO.File.Create(res);
        s.Close();
        break;
      }
      catch (Exception) {

      }
    }
  }
  return res;
} // GetTempFile

Update (2008-09-19 10:05) - Solution:

My Solution: Social engineering, I dug real hard and found someone who knew the schema name.
Technical Solution: Searching the .dmp file did yield the schema name.
Once I knew the schema name, I searched the dump file and learned where to find it.

Places the Schemas name were seen, in the .dmp file:

• <OWNER_NAME>SOURCE_SCHEMA</OWNER_NAME> This was seen before each table name/definition.

• SCHEMA_LIST 'SOURCE_SCHEMA' This was seen near the end of the .dmp.

Interestingly enough, around the SCHEMA_LIST 'SOURCE_SCHEMA' section, it also had the command line used to create the dump, directories used, par files used, windows version it was run on, and export session settings (language, date formats).

So, problem solved :)

I found this script somewhere. I don't remember where, but it works for me:

#!/bin/ksh

line='---------------------------------------------'
pids=$(/usr/bin/ps -ef | sed 1d | awk '{print $2}')

if [ $# -eq 0 ]; then
   read ans?"Enter port you would like to know pid for: "
else
   ans=$1
fi

for f in $pids
do
   /usr/proc/bin/pfiles $f 2>/dev/null | /usr/xpg4/bin/grep -q "port: $ans"
   if [ $? -eq 0 ]; then
      echo $line
      echo "Port: $ans is being used by PID:\c"
      /usr/bin/ps -ef -o pid -o args | egrep -v "grep|pfiles" | grep $f
   fi
done
exit 0

__func__ is documented in the C++0x standard at section 8.4.1. In this case it's a predefined function local variable of the form:

static const char __func__[] = "function-name ";

where "function name" is implementation specfic. This means that whenever you declare a function, the compiler will add this variable implicitly to your function. The same is true of __FUNCTION__ and __PRETTY_FUNCTION__. Despite their uppercasing, they aren't macros. Although __func__ is an addition to C++0x

g++ -std=c++98 ....

will still compile code using __func__.

__PRETTY_FUNCTION__ and __FUNCTION__ are documented here http://gcc.gnu.org/onlinedocs/gcc-4.5.1/gcc/Function-Names.html#Function-Names. __FUNCTION__ is just another name for __func__. __PRETTY_FUNCTION__ is the same as __func__ in C but in C++ it contains the type signature as well.

Just check if the aopalliance.jar file has .java files instead of .class files. if so, just extract the jar file, import it in eclipse & create a jar though eclipse. It worked for me.

This is the best solution ever rather than hacking CSS.

You should have to click your map - $('#map-selector').click();

You have to construct a new string out of a byte array. The first element in your byteArray should be 0x63. If you want to add any more letters, make the byteArray longer and add them to the next indices.

byte[] byteArray = new byte[1];
byteArray[0] = 0x63;

try {
    System.out.println("string " + new String(byteArray, "US-ASCII"));
} catch (UnsupportedEncodingException e) {
    // TODO: Handle exception.
    e.printStackTrace();
}

Note that specifying the encoding will eventually throw an UnsupportedEncodingException and you must handle that accordingly.

You can now do this without the use of Android SDK.

In the latest version of chrome (I am working on 34.0.x):

• Navigate to chrome://inspect/
• Check Discover USB Devices
• Plug in your phone via USB. A popup should spawn asking for permission to connect to your computer. Accept it.

There will now be an item on the chrome://inspect/ pages for your phone, and you can click inspect. Dev tools will spawn and voila!

default_data['item3'] = 3

Easy as py.

Another possible solution:

default_data.update({'item3': 3})

which is nice if you want to insert multiple items at once.

You might have 10,000 users total, but that's not the same as concurrent users. In this context, concurrent scripts being run.

For example, if your visitor visits index.php, and it makes a database query to get some user details, that request might live for 250ms. You can limit how long those MySQL connections live even further by opening and closing them only when you are querying, instead of leaving it open for the duration of the script.

While it is hard to make any type of formula to predict how many connections would be open at a time, I'd venture the following:

You probably won't have more than 500 active users at any given time with a user base of 10,000 users. Of those 500 concurrent users, there will probably at most be 10-20 concurrent requests being made at a time.

That means, you are really only establishing about 10-20 concurrent requests.

As others mentioned, you have nothing to worry about in that department.

Browsers can often tell the image type by sniffing out the meta information of the image. Also, there should be a space in that header:

header('Content-type: image/png');

Answer is already given above. Trying to differentiate between strong vs week and static vs dynamic concept.

What is Strongly typed VS Weakly typed?

Strongly Typed: Will not be automatically converted from one type to another

In Go or Python like strongly typed languages "2" + 8 will raise a type error, because they don't allow for "type coercion".

Weakly (loosely) Typed: Will be automatically converted to one type to another: Weakly typed languages like JavaScript or Perl won't throw an error and in this case JavaScript will results '28' and perl will result 10.

Perl Example:

my $a = "2" + 8;
print $a,"\n";

Save it to main.pl and run perl main.pl and you will get output 10.

What is Static VS Dynamic type?

In programming, programmer define static typing and dynamic typing with respect to the point at which the variable types are checked. Static typed languages are those in which type checking is done at compile-time, whereas dynamic typed languages are those in which type checking is done at run-time.

• Static: Types checked before run-time
• Dynamic: Types checked on the fly, during execution

What is this means?

In Go it checks typed before run-time (static check). This mean it not only translates and type-checks code it’s executing, but it will scan through all the code and type error would be thrown before the code is even run. For example,

package main

import "fmt"

func foo(a int) {
    if (a > 0) {
        fmt.Println("I am feeling lucky (maybe).")
    } else {
        fmt.Println("2" + 8)
    }
}

func main() {
    foo(2)
}

Save this file in main.go and run it, you will get compilation failed message for this.

go run main.go
# command-line-arguments
./main.go:9:25: cannot convert "2" (type untyped string) to type int
./main.go:9:25: invalid operation: "2" + 8 (mismatched types string and int)

But this case is not valid for Python. For example following block of code will execute for first foo(2) call and will fail for second foo(0) call. It's because Python is dynamically typed, it only translates and type-checks code it’s executing on. The else block never executes for foo(2), so "2" + 8 is never even looked at and for foo(0) call it will try to execute that block and failed.

def foo(a):
    if a > 0:
        print 'I am feeling lucky.'
    else:
        print "2" + 8
foo(2)
foo(0)

You will see following output

python main.py
I am feeling lucky.
Traceback (most recent call last):
  File "pyth.py", line 7, in <module>
    foo(0)
  File "pyth.py", line 5, in foo
    print "2" + 8
TypeError: cannot concatenate 'str' and 'int' objects

You can fix broken serialize string using following function, with multibyte character handling.

function repairSerializeString($value)
{

    $regex = '/s:([0-9]+):"(.*?)"/';

    return preg_replace_callback(
        $regex, function($match) {
            return "s:".mb_strlen($match[2]).":\"".$match[2]."\""; 
        },
        $value
    );
}

You can do like..

DataRow[] dr = dtbl.Select("SUM(Amount)");
txtTotalAmount.Text = Convert.ToString(dr[0]);

Naive Bayes: Naive Bayes comes under supervising machine learning which used to make classifications of data sets. It is used to predict things based on its prior knowledge and independence assumptions.

They call it naive because it’s assumptions (it assumes that all of the features in the dataset are equally important and independent) are really optimistic and rarely true in most real-world applications.

It is classification algorithm which makes the decision for the unknown data set. It is based on Bayes Theorem which describe the probability of an event based on its prior knowledge.

Below diagram shows how naive Bayes works

Formula to predict NB:

How to use Naive Bayes Algorithm ?

Let's take an example of how N.B woks

Step 1: First we find out Likelihood of table which shows the probability of yes or no in below diagram. Step 2: Find the posterior probability of each class.

Problem: Find out the possibility of whether the player plays in Rainy condition?

P(Yes|Rainy) = P(Rainy|Yes) * P(Yes) / P(Rainy)

P(Rainy|Yes) = 2/9 = 0.222
P(Yes) = 9/14 = 0.64
P(Rainy) = 5/14 = 0.36

Now, P(Yes|Rainy) = 0.222*0.64/0.36 = 0.39 which is lower probability which means chances of the match played is low.

You should be able to use a wildcard for your values:

switch -wildcard ($someString.ToLower())
{
    "y*" { "You entered Yes." }
    default { "You entered No." }
}

Regular expressions are also allowed.

switch -regex ($someString.ToLower())
{
    "y(es)?" { "You entered Yes." }
    default { "You entered No." }
}

In my case also \n was not working, I fixed issue by keeping number of lines to 0 and copied and pasted the text with new line itself for example instead of Hello \n World i pasted

First of all, public static non-final fields are evil. Spring does not allow injecting to such fields for a reason.

Your workaround is valid, you don't even need getter/setter, private field is enough. On the other hand try this:

@Value("${my.name}")
public void setPrivateName(String privateName) {
    Sample.name = privateName;
}  

(works with @Autowired/@Resource). But to give you some constructive advice: Create a second class with private field and getter instead of public static field.

You could use pandas plot as @Bharath suggest:

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

Output:

Updated:

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

Updated Pandas 0.21.0+ reindex_axis is deprecated, use reindex

from matplotlib.colors import ListedColormap

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

Output:

In intellij8 I was using a specific plugin "Jar Tool" that is configurable and allows to pack a JAR archive.

A parameter is the variable which is part of the method’s signature (method declaration). An argument is an expression used when calling the method.

Consider the following code:

void Foo(int i, float f)
{
    // Do things
}

void Bar()
{
    int anInt = 1;
    Foo(anInt, 2.0);
}

Here i and f are the parameters, and anInt and 2.0 are the arguments.

Meaning the 2nd parameter('master') of the "git push" command -

$ git push origin master

can be made clear by initiating "push" command from 'news-item' branch. It caused local "master" branch to be pushed to the remote 'master' branch. For more information refer

https://git-scm.com/docs/git-push

where <refspec> in

[<repository> [<refspec>…?]

is written to mean "specify what destination ref to update with what source object."

For your reference, here is a screen capture how I verified this statement.

It runs Java compiled code, it can maintain database connection pools, it can log errors of various types. I'd call it an application server, in fact I do. In our environment we have Apache as the webserver fronting a number of different application servers, including Tomcat and Coldfusion, and others.

This reg ex is suitable for international phone numbers and multiple formats of mobile cell numbers.

Here is the regular expression: /^(+{1}\d{2,3}\s?[(]{1}\d{1,3}[)]{1}\s?\d+|+\d{2,3}\s{1}\d+|\d+){1}[\s|-]?\d+([\s|-]?\d+){1,2}$/

Here is the JavaScript function

function isValidPhone(phoneNumber) {
    var found = phoneNumber.search(/^(\+{1}\d{2,3}\s?[(]{1}\d{1,3}[)]{1}\s?\d+|\+\d{2,3}\s{1}\d+|\d+){1}[\s|-]?\d+([\s|-]?\d+){1,2}$/);
    if(found > -1) {
        return true;
    }
    else {
        return false;
    }
}

This validates the following formats:

+44 07988-825 465 (with any combination of hyphens in place of space except that only a space must follow the +44)

+44 (0) 7988-825 465 (with any combination of hyphens in place of spaces except that no hyphen can exist directly before or after the (0) and the space before or after the (0) need not exist)

123 456-789 0123 (with any combination of hyphens in place of the spaces)

123-123 123 (with any combination of hyphens in place of the spaces)

123 123456 (Space can be replaced with a hyphen)

1234567890

No double spaces or double hyphens can exist for all formats.

I think the question asker is (was) thinking that git bash is a command like git init or git checkout. Git bash is not a command, it is an interface. I will also assume the asker is not a linux user because bash is very popular the unix/linux world. The name "bash" is an acronym for "Bourne Again SHell". Bash is a text-only command interface that has features which allow automated scripts to be run. A good analogy would be to compare bash to the new PowerShell interface in Windows7/8. A poor analogy (but one likely to be more readily understood by more people) is the combination of the command prompt and .BAT (batch) command files from the days of DOS and early versions of Windows.

Solution for Windows 7 and Nexus 5 (should be applicable for any Nexus device):

I figured out that my system was installing the Nexus 5 default driver for windows automatically the moment I was connecting my Nexus 5 to my system through USB. So uninstalling the default driver was in vain and it gets installed automatically anyways.Moreover if you uninstall the default driver, you won't be able to locate Nexus 5 under Devices in Computer Management. So here is what i did and worked for me!

1. Computer-->right Click-->Manage-->Device Manager-->Portable Device-->Nexus 5-->Update Driver Software
2. Choose 'Browse my computer for driver software' 1.Make sure to give this location: %APPDATA%\Local\Android\sdk\extras\google\usb_driver
3. Click Next and you are done.

or you can just allocate a 1D array but reference elements in a 2D fashion:

to address row 2, column 3 (top left corner is row 0, column 0):

arr[2 * MATRIX_WIDTH + 3]

where MATRIX_WIDTH is the number of elements in a row.

If you're dealing with optional Strings, this works:

(string ?? "").isEmpty

The ?? nil coalescing operator returns the left side if it's non-nil, otherwise it returns the right side.

You can also use it like this to return a default value:

(string ?? "").isEmpty ? "Default" : string!

In Objective-C all methods start with either a "-" or "+" character. Example:

@interface MyClass : NSObject
// instance method
- (void) instanceMethod;

+ (void) classMethod;
@end

The "+" and "-" characters specify whether a method is a class method or an instance method respectively.

The difference would be clear if we call these methods. Here the methods are declared in MyClass.

instance method require an instance of the class:

MyClass* myClass = [[MyClass alloc] init];
[myClass instanceMethod];

Inside MyClass other methods can call instance methods of MyClass using self:

-(void) someMethod
{
    [self instanceMethod];
}

But, class methods must be called on the class itself:

[MyClass classMethod];

Or:

MyClass* myClass = [[MyClass alloc] init];
[myClass class] classMethod];

This won't work:

// Error
[myClass classMethod];
// Error
[self classMethod];

Manifest.MF contains information about the files contained in the JAR file.

Whenever a JAR file is created a default manifest.mf file is created inside META-INF folder and it contains the default entries like this:

Manifest-Version: 1.0
Created-By: 1.7.0_06 (Oracle Corporation)

These are entries as “header:value” pairs. The first one specifies the manifest version and second one specifies the JDK version with which the JAR file is created.

Main-Class header: When a JAR file is used to bundle an application in a package, we need to specify the class serving an entry point of the application. We provide this information using ‘Main-Class’ header of the manifest file,

Main-Class: {fully qualified classname}

The ‘Main-Class’ value here is the class having main method. After specifying this entry we can execute the JAR file to run the application.

Class-Path header: Most of the times we need to access the other JAR files from the classes packaged inside application’s JAR file. This can be done by providing their fully qualified paths in the manifest file using ‘Class-Path’ header,

Class-Path: {jar1-name jar2-name directory-name/jar3-name}

This header can be used to specify the external JAR files on the same local network and not inside the current JAR.

Package version related headers: When the JAR file is used for package versioning the following headers are used as specified by the Java language specification:

Headers in a manifest
Header                  | Definition
-------------------------------------------------------------------
Name                    | The name of the specification.
Specification-Title     | The title of the specification.
Specification-Version   | The version of the specification.
Specification-Vendor    | The vendor of the specification.
Implementation-Title    | The title of the implementation.
Implementation-Version  | The build number of the implementation.
Implementation-Vendor   | The vendor of the implementation.

Package sealing related headers:

We can also specify if any particular packages inside a JAR file should be sealed meaning all the classes defined in that package must be archived in the same JAR file. This can be specified with the help of ‘Sealed’ header,

Name: {package/some-package/} Sealed:true

Here, the package name must end with ‘/’.

Enhancing security with manifest files:

We can use manifest files entries to ensure the security of the web application or applet it packages with the different attributes as ‘Permissions’, ‘Codebae’, ‘Application-Name’, ‘Trusted-Only’ and many more.

META-INF folder:

This folder is where the manifest file resides. Also, it can contain more files containing meta data about the application. For example, in an EJB module JAR file, this folder contains the EJB deployment descriptor for the EJB module along with the manifest file for the JAR. Also, it contains the xml file containing mapping of an abstract EJB references to concrete container resources of the application server on which it will be run.

Reference:
https://docs.oracle.com/javase/tutorial/deployment/jar/manifestindex.html

Add MultipleActiveResultSets=true to the provider part of your connection string example in the file appsettings.json

"ConnectionStrings": {
"EmployeeDBConnection": "server=(localdb)\\MSSQLLocalDB;database=YourDatabasename;Trusted_Connection=true;MultipleActiveResultSets=true"}

To start multiple containers with the only particular container id's $ docker restart contianer-id1 container-id2 container-id3 ...

This should work in most cases.

SELECT * FROM myTable WHERE concat('',col1 * 1) = col1

It doesn't work for non-standard numbers like

• 1e4
• 1.2e5
• 123. (trailing decimal)

This cannot be done with the native javascript dialog box, but a lot of javascript libraries include more flexible dialogs. You can use something like jQuery UI's dialog box for this.

See also these very similar questions:

• JavaScript confirm box with custom buttons
• custom choices in javascript confirm dialog

Here's an example, as demonstrated in this jsFiddle:

    <script type="text/javascript">

        $(function() {
            $('.checked').click(function(e) {
                e.preventDefault();
                var dialog = $('<p>Are you sure?</p>').dialog({
                    buttons: {
                        "Yes": function() {alert('you chose yes');},
                        "No":  function() {alert('you chose no');},
                        "Cancel":  function() {
                            alert('you chose cancel');
                            dialog.dialog('close');
                        }
                    }
                });
            });
        });

    </script>
</body><html>

I also had a requirement something similar to it. I wanted to have a container in the center of the screen and inside the container there are many views. Following is the xml layout code. Here i'm using nested constraint layout to create container in the center of the screen.

Other solution is to remove the nested constraint layout and add constraint_vertical_bias = 0.5 attribute to the top element in the center of layout. I think this is called as chaining of views.

Here is the screenshot of the layout

I'd extend the Array class with a pick_and_remove() function, like so:

var ArrayInstanceExtensions = {
    pick_and_remove: function(index){
        var picked_element = this[index];
        this.splice(index,1);
        return picked_element;
    } 
};
$.extend(Array.prototype, ArrayInstanceExtensions);

While it may seem a bit verbose, you can now call pick_and_remove() on any array you possibly want!

Usage:

array = [4,5,6]           //=> [4,5,6]
array.pick_and_remove(1); //=> 5
array;                    //=> [4,6]

You can see all of this in pokemon-themed action here.

grep's -A 1 option will give you one line after; -B 1 will give you one line before; and -C 1 combines both to give you one line both before and after, -1 does the same.

We see this a lot with OAuth2 integrations. We provide API services to our Customers, and they'll naively try to put their private key into an AJAX call. This is really poor security. And well-coded API Gateways, backends for frontend, and other such proxies, do not allow this. You should get this error.

I will quote @aspillers comment and change a single word: "Access-Control-Allow-Origin is a header sent in a server response which indicates IF the client is allowed to see the contents of a result".

ISSUE: The problem is that a developer is trying to include their private key inside a client-side (browser) JavaScript request. They will get an error, and this is because they are exposing their client secret.

SOLUTION: Have the JavaScript web application talk to a backend service that holds the client secret securely. That backend service can authenticate the web app to the OAuth2 provider, and get an access token. Then the web application can make the AJAX call.

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

class MultiArg {

    Scanner sc;
    int n;
    String as;
    List<Integer> numList = new ArrayList<Integer>();

    public void fun() {
        sc = new Scanner(System.in);
        System.out.println("enter value");
        while (sc.hasNextInt())
            as = sc.nextLine();
    }

    public void diplay() {
        System.out.println("x");
        Integer[] num = numList.toArray(new Integer[numList.size()]);
        System.out.println("show value " + as);
        for (Integer m : num) {
            System.out.println("\t" + m);
        }
    }
}

but to terminate the while loop you have to put any charecter at the end of input.

ex. input:

12 34 56 78 45 67 .

output:

12 34 56 78 45 67

Yes, it is normal. This is because you checkout a single commit, that doesnt have a head. Especially it is (sooner or later) not a head of any branch.

But there is usually no problem with that state. You may create a new branch from the tag, if this makes you feel safer :)

the easiest way to compare the sequence item with the following:

for i, j in zip(a, a[1:]):
     # compare i (the current) to j (the following)

You can use this:

let s = "This is my string"
let modified = s.replace(" ", withString:"+")    

If you add this extension method anywhere in your code:

extension String
{
    func replace(target: String, withString: String) -> String
    {
       return self.stringByReplacingOccurrencesOfString(target, withString: withString, options: NSStringCompareOptions.LiteralSearch, range: nil)
    }
}

Swift 3:

extension String
{
    func replace(target: String, withString: String) -> String
    {
        return self.replacingOccurrences(of: target, with: withString, options: NSString.CompareOptions.literal, range: nil)
    }
}

I think these pictures are understandable.

var Hello = React.createClass({
    render: function() {
      return (
        <div className="divClass">
           <img src={this.props.url} alt={`${this.props.title}'s picture`}  className="img-responsive" />
           <span>Hello {this.props.name}</span>
        </div>
      );
    }
});

I am new to Rust, but this solution seems to work:

#[macro_use]
extern crate lazy_static;

use std::sync::{Arc, Mutex};

lazy_static! {
    static ref GLOBAL: Arc<Mutex<GlobalType> =
        Arc::new(Mutex::new(GlobalType::new()));
}

Another solution is to declare a crossbeam channel tx/rx pair as an immutable global variable. The channel should be bounded and can only hold 1 element. When you initialize the global variable, push the global instance into the channel. When using the global variable, pop the channel to acquire it and push it back when done using it.

Both solutions should provide a safe approach to using global variables.

Not necessarily better, but since it's nice to have options here's how to do it using Jinja statements:

    msg: "{% for address in network.addresses.private_man %}\
        {% if address.type == 'fixed' %}\
          {{ address.addr }}\
        {% endif %}\
      {% endfor %}"

Or if you prefer to put it all on one line:

- debug:
    msg: "{% for address in network.addresses.private_man if address.type == 'fixed' %}{{ address.addr }}{% endfor %}"

Which returns:

ok: [localhost] => {
    "msg": "172.16.1.100"
}

I presume SELECT user FROM dual; should give you the current user

and SELECT sys_context('userenv','instance_name') FROM dual; the name of the instance

I believe you can get SID as SELECT sys_context('USERENV', 'SID') FROM DUAL;

It may be late but there is a new simple solution to this question for who ever wants it.
In kotlin

val player = MediaPlayer.create(this,Settings.System.DEFAULT_RINGTONE_URI)
player.start()

Above code will play default ringtone but if you want default alarm, change

Settings.System.DEFAULT_RINGTONE_URI

to

Settings.System.DEFAULT_ALARM_ALERT_URI

class atdict(dict):
  def __init__(self, value, **kwargs):
    super().__init__(**kwargs)
    self.__dict = value

  def __getattr__(self, name):
    for key in self.__dict:
      if type(self.__dict[key]) is list:
        for idx, item in enumerate(self.__dict[key]):
          if type(item) is dict:
            self.__dict[key][idx] = atdict(item)
      if type(self.__dict[key]) is dict:
        self.__dict[key] = atdict(self.__dict[key])
    return self.__dict[name]



d1 = atdict({'a' : {'b': [{'c': 1}, 2]}})

print(d1.a.b[0].c)

And the output is:

>> 1

The selected answer would work for as long as you know the key itself that you want to delete but if it should be truly dynamic you would need to use the [] notation instead of the dot notation.

For example:

var keyToDelete = "key1";
var myObj = {"test": {"key1": "value", "key2": "value"}}

//that will not work.
delete myObj.test.keyToDelete 

instead you would need to use:

delete myObj.test[keyToDelete];

Substitute the dot notation with [] notation for those values that you want evaluated before being deleted.

I have used

str.replace("'", "");

to replace the single quote in my string. Its working fine for me.

I have used the gulp-order plugin but it is not always successful as you can see by my stack overflow post gulp-order node module with merged streams. When browsing through the Gulp docs I came across the streamque module which has worked quite well for specifying order of in my case concatenation. https://github.com/gulpjs/gulp/blob/master/docs/recipes/using-multiple-sources-in-one-task.md

Example of how I used it is below

var gulp         = require('gulp');
var concat       = require('gulp-concat');
var handleErrors = require('../util/handleErrors');
var streamqueue  = require('streamqueue');

gulp.task('scripts', function() {
    return streamqueue({ objectMode: true },
        gulp.src('./public/angular/config/*.js'),
        gulp.src('./public/angular/services/**/*.js'),
        gulp.src('./public/angular/modules/**/*.js'),
        gulp.src('./public/angular/primitives/**/*.js'),
        gulp.src('./public/js/**/*.js')
    )
        .pipe(concat('app.js'))
        .pipe(gulp.dest('./public/build/js'))
        .on('error', handleErrors);
});

There is a limit on the number of half-open connections, but afaik not for active connections. Although it appears to depend on the type of Windows 2008 server, at least according to this MSFT employee:

It depends on the edition, Web and Foundation editions have connection limits while Standard, Enterprise, and Datacenter do not.

By default, no you can't know if a variable (or pointer) has or hasn't been initialized. However, since everyone else is telling you the "easy" or "normal" approach, I'll give you something else to think about. Here's how you could keep track of something like that (no, I personally would never do this, but perhaps you have different needs than me).

class MyVeryCoolInteger
{
public:
    MyVeryCoolInteger() : m_initialized(false) {}

    MyVeryCoolInteger& operator=(const int integer)
    {
        m_initialized = true;
        m_int = integer;
        return *this;
    }

    int value()
    {
        return m_int;
    }

    bool isInitialized()
    {
        return m_initialized;
    }

private:
    int m_int;
    bool m_initialized;
};

In v7.7, I had to go to Plugins menu and select "Open Plugins Folder..." (which goes to C:\Program Files\Notepad++\plugins).

I had to create a folder for the plugin and extract the .dll into the folder. For example, create a folder called "JSMinNPP" and place the "JSMinNPP.dll" in that folder. It doesn't work if you put the dll into the plugins folder.

Finally go to Settings --> Import --> Import plugin(s) and import that dll and restart Notepad++.

I think you've actually got a wider confusion here.

The initial error is that you're trying to call split on the whole list of lines, and you can't split a list of strings, only a string. So, you need to split each line, not the whole thing.

And then you're doing for points in Type, and expecting each such points to give you a new x and y. But that isn't going to happen. Types is just two values, x and y, so first points will be x, and then points will be y, and then you'll be done. So, again, you need to loop over each line and get the x and y values from each line, not loop over a single Types from a single line.

So, everything has to go inside a loop over every line in the file, and do the split into x and y once for each line. Like this:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    readfile = open(filename, "r")

    for line in readfile:
        Type = line.split(",")
        x = Type[1]
        y = Type[2]
        print(x,y)

getQuakeData()

As a side note, you really should close the file, ideally with a with statement, but I'll get to that at the end.

Interestingly, the problem here isn't that you're being too much of a newbie, but that you're trying to solve the problem in the same abstract way an expert would, and just don't know the details yet. This is completely doable; you just have to be explicit about mapping the functionality, rather than just doing it implicitly. Something like this:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    readfile = open(filename, "r")
    readlines = readfile.readlines()
    Types = [line.split(",") for line in readlines]
    xs = [Type[1] for Type in Types]
    ys = [Type[2] for Type in Types]
    for x, y in zip(xs, ys):
        print(x,y)

getQuakeData()

Or, a better way to write that might be:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    # Use with to make sure the file gets closed
    with open(filename, "r") as readfile:
        # no need for readlines; the file is already an iterable of lines
        # also, using generator expressions means no extra copies
        types = (line.split(",") for line in readfile)
        # iterate tuples, instead of two separate iterables, so no need for zip
        xys = ((type[1], type[2]) for type in types)
        for x, y in xys:
            print(x,y)

getQuakeData()

Finally, you may want to take a look at NumPy and Pandas, libraries which do give you a way to implicitly map functionality over a whole array or frame of data almost the same way you were trying to.

To replace only factors:

i <- sapply(bob, is.factor)
bob[i] <- lapply(bob[i], as.character)

In package dplyr in version 0.5.0 new function mutate_if was introduced:

library(dplyr)
bob %>% mutate_if(is.factor, as.character) -> bob

...and in version 1.0.0 was replaced by across:

library(dplyr)
bob %>% mutate(across(where(is.factor), as.character)) -> bob

Package purrr from RStudio gives another alternative:

library(purrr)
bob %>% modify_if(is.factor, as.character) -> bob

You want to apply a custom formatting rule. The "Applies to" field should be your entire row (If you want to format row 5, put in =$5:$5. The custom formula should be =IF($B$5="X", TRUE, FALSE), shown in the example below.

Most easiest way is to use ViewTreeObserver, if you directly use .height or .width you get values as 0, due to views are not have size until they draw on our screen. Following example will show how to use ViewTreeObserver

ViewTreeObserver viewTreeObserver = YOUR_VIEW_TO_MEASURE.getViewTreeObserver();
        if (viewTreeObserver.isAlive()) {
            viewTreeObserver.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
                @Override
                public void onGlobalLayout() {

                    YOUR_VIEW_TO_MEASURE.getViewTreeObserver().removeOnGlobalLayoutListener(this);
                    int viewHeight = YOUR_VIEW_TO_MEASURE.getHeight();
                    int viewWeight = YOUR_VIEW_TO_MEASURE.getWidth();

                }
            });
        }

if you need to use this on method, use like this and to save the values you can use globle variables.

i was facing the similar issue and i resolved by using following code

$(document).on('click', 'a.page-scroll', function(event) {
        var $anchor = $(this);
        var desiredHeight = $(window).height() - 577;
        $('html, body').stop().animate({
            scrollTop: $($anchor.attr('href')).offset().top - desiredHeight
        }, 1500, 'easeInOutExpo');
        event.preventDefault();
    });

OP's solution to his problem, as he says, has dubious output. That code still shows confusion about representations of time. To clear up this confusion, and make code that won't lead to wrong times, consider this extension of what he did:

public static void _testDateFormatting() {
    SimpleDateFormat sdfGMT1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
    sdfGMT1.setTimeZone(TimeZone.getTimeZone("GMT"));
    SimpleDateFormat sdfGMT2 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss z");
    sdfGMT2.setTimeZone(TimeZone.getTimeZone("GMT"));

    SimpleDateFormat sdfLocal1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
    SimpleDateFormat sdfLocal2 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss z");

    try {
        Date d = new Date();
        String s1 = d.toString();
        String s2 = sdfLocal1.format(d);
        // Store s3 or s4 in database.
        String s3 = sdfGMT1.format(d);
        String s4 = sdfGMT2.format(d);
        // Retrieve s3 or s4 from database, using LOCAL sdf.
        String s5 = sdfLocal1.parse(s3).toString();
        //EXCEPTION String s6 = sdfLocal2.parse(s3).toString();
        String s7 = sdfLocal1.parse(s4).toString();
        String s8 = sdfLocal2.parse(s4).toString();
        // Retrieve s3 from database, using GMT sdf.
        // Note that this is the SAME sdf that created s3.
        Date d2 = sdfGMT1.parse(s3);
        String s9 = d2.toString();
        String s10 = sdfGMT1.format(d2);
        String s11 = sdfLocal2.format(d2);
    } catch (Exception e) {
        e.printStackTrace();
    }       
}

examining values in a debugger:

s1  "Mon Sep 07 06:11:53 EDT 2015" (id=831698113128)    
s2  "2015.09.07 06:11:53" (id=831698114048) 
s3  "2015.09.07 10:11:53" (id=831698114968) 
s4  "2015.09.07 10:11:53 GMT+00:00" (id=831698116112)   
s5  "Mon Sep 07 10:11:53 EDT 2015" (id=831698116944)    
s6  -- omitted, gave parse exception    
s7  "Mon Sep 07 10:11:53 EDT 2015" (id=831698118680)    
s8  "Mon Sep 07 06:11:53 EDT 2015" (id=831698119584)    
s9  "Mon Sep 07 06:11:53 EDT 2015" (id=831698120392)    
s10 "2015.09.07 10:11:53" (id=831698121312) 
s11 "2015.09.07 06:11:53 EDT" (id=831698122256) 

sdf2 and sdfLocal2 include time zone, so we can see what is really going on. s1 & s2 are at 06:11:53 in zone EDT. s3 & s4 are at 10:11:53 in zone GMT -- equivalent to the original EDT time. Imagine we save s3 or s4 in a data base, where we are using GMT for consistency, so we can have times from anywhere in the world, without storing different time zones.

s5 parses the GMT time, but treats it as a local time. So it says "10:11:53" -- the GMT time -- but thinks it is 10:11:53 in local time. Not good.

s7 parses the GMT time, but ignores the GMT in the string, so still treats it as a local time.

s8 works, because now we include GMT in the string, and the local zone parser uses it to convert from one time zone to another.

Now suppose you don't want to store the zone, you want to be able to parse s3, but display it as a local time. The answer is to parse using the same time zone it was stored in -- so use the same sdf as it was created in, sdfGMT1. s9, s10, & s11 are all representations of the original time. They are all "correct". That is, d2 == d1. Then it is only a question of how you want to DISPLAY it. If you want to display what is stored in DB -- GMT time -- then you need to format it using a GMT sdf. Ths is s10.

So here is the final solution, if you don't want to explicitly store with " GMT" in the string, and want to display in GMT format:

public static void _testDateFormatting() {
    SimpleDateFormat sdfGMT1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
    sdfGMT1.setTimeZone(TimeZone.getTimeZone("GMT"));

    try {
        Date d = new Date();
        String s3 = sdfGMT1.format(d);
        // Store s3 in DB.
        // ...
        // Retrieve s3 from database, using GMT sdf.
        Date d2 = sdfGMT1.parse(s3);
        String s10 = sdfGMT1.format(d2);
    } catch (Exception e) {
        e.printStackTrace();
    }       
}

if you want to get the variables of sections you can pay like this:

$_view      = new \View;
$_sections  = $_view->getFacadeRoot()->getSections();
dd($_sections);
/*
Out:
array:1 [?
  "title" => "Painel"
]
*/

If you are sure there is a " at the beginning and at the end, which you want to remove, just do:

string = string[1:len(string)-1]

or

string = string[1:-1]

I'm glad that worked out, so I guess you had to explicitly set 'auto' on IE6 in order for it to mimic other browsers!

I actually recently found another technique for scaling images, again designed for backgrounds. This technique has some interesting features:

1. The image aspect ratio is preserved
2. The image's original size is maintained (that is, it can never shrink only grow)

The markup relies on a wrapper element:

<div id="wrap"><img src="test.png" /></div>

Given the above markup you then use these rules:

#wrap {
  height: 100px;
  width: 100px;
}
#wrap img {
  min-height: 100%;
  min-width: 100%;
}

If you then control the size of wrapper you get the interesting scale effects that I list above.

To be explicit, consider the following base state: A container that is 100x100 and an image that is 10x10. The result is a scaled image of 100x100.

1. Starting at the base state, the container resized to 20x100, the image stays resized at 100x100.
2. Starting at the base state, the image is changed to 10x20, the image resizes to 100x200.

So, in other words, the image is always at least as big as the container, but will scale beyond it to maintain it's aspect ratio.

This probably isn't useful for your site, and it doesn't work in IE6. But, it is useful to get a scaled background for your view port or container.

You can use also the Insert/update/delete datagrid of my MVC Controls Toolkit available here on codeplex: http://mvccontrolstoolkit.codeplex.com/. Here you can download a complete example, here the datagrid working and here and here tutorials. The DataGrid works completely client side and mantains thechange set between posts. Yes it mantains Changeset, this means, you can access both old version and modified version of each record to see what changes to pass to the DB(what need to be modified deleted or inserted). This Changeset is mantained after several posts till you either confirm or cancel the modifications on the server side.

Well, the AssetManager lists files within the assets folder that is inside of your APK file. So what you're trying to list in your example above is [apk]/assets/sdcard/Pictures.

If you put some pictures within the assets folder inside of your application, and they were in the Pictures directory, you would do mgr.list("/Pictures/").

On the other hand, if you have files on the sdcard that are outside of your APK file, in the Pictures folder, then you would use File as so:

File file = new File(Environment.getExternalStorageDirectory(), "Pictures");
File[] pictures = file.listFiles();
...
for (...)
{
log.e("FILE:", pictures[i].getAbsolutePath());
}

And relevant links from the docs:
File
Asset Manager

Ah yes, that is how it is intended in SQL. You get the Max of every column seperately. It seems like you want to return values from the row with the max date, so you have to select the row with the max date. I prefer to do this with a subselect, as the queries keep compact easy to read.

SELECT TrainingID, CompletedDate, Notes
FROM HR_EmployeeTrainings ET 
WHERE (ET.AvantiRecID IS NULL OR ET.AvantiRecID = @avantiRecID) 
AND CompletedDate in 
   (Select Max(CompletedDate) from HR_EmployeeTrainings B
    where B.TrainingID = ET.TrainingID)

If you also want to match by AntiRecID you should include that in the subselect as well.

You give the name of your file, the path of the directory to search, and let it make the job.

private static String getPath(String drl, String whereIAm) {
    File dir = new File(whereIAm); //StaticMethods.currentPath() + "\\src\\main\\resources\\" + 
    for(File e : dir.listFiles()) {
        if(e.isFile() && e.getName().equals(drl)) {return e.getPath();}
        if(e.isDirectory()) {
            String idiot = getPath(drl, e.getPath());
            if(idiot != null) {return idiot;}
        }
    }
    return null;
}

Don't worry... Its much easy to solve your problem. Just SET you SDK-LOCATION and JDK-LOCATION.

• Click on Configure ( As Soon Android studio open )
• Click Project Default
• Click Project Structure

• Clik Android Sdk Location

• Select & Browse your Android SDK Location (Like: C:\Android\sdk)

• Uncheck USE EMBEDDED JDK LOCATION

• Set & Browse JDK Location, Like C:\Program Files\Java\jdk1.8.0_121

This should kind of work like die();

function die(msg = ''){

The debugger should automatically attach to the browser with Visual Studio 2012. You can use the debugger keyword to halt at a certain point in the application or use the breakpoints directly inside VS.

You can also detatch the default debugger in Visual Studio and use the Developer Tools which come pre loaded with Internet Explorer or FireBug etc.

To do this goto Visual Studio -> Debug -> Detatch All and then click Start debugging in Internet Explorer. You can then set breakpoints at this level.

Here is a function I use to execute sql commands. You just have to change $sqlCommand.CommandText to the name of your sproc and $SqlCommand.CommandType to CommandType.StoredProcedure.

function execute-Sql{
    param($server, $db, $sql )
    $sqlConnection = new-object System.Data.SqlClient.SqlConnection
    $sqlConnection.ConnectionString = 'server=' + $server + ';integrated security=TRUE;database=' + $db 
    $sqlConnection.Open()
    $sqlCommand = new-object System.Data.SqlClient.SqlCommand
    $sqlCommand.CommandTimeout = 120
    $sqlCommand.Connection = $sqlConnection
    $sqlCommand.CommandText= $sql
    $text = $sql.Substring(0, 50)
    Write-Progress -Activity "Executing SQL" -Status "Executing SQL => $text..."
    Write-Host "Executing SQL => $text..."
    $result = $sqlCommand.ExecuteNonQuery()
    $sqlConnection.Close()
}

After some years have passed, you can do that now with ES6 Array.from (or spread syntax):

const navbar = Array.from(document.querySelectorAll('#navbar>ul>li'));_x000D_
console.log('Get first: ', navbar[0].textContent);_x000D_
_x000D_
// If you need to iterate once over all these nodes, you can use the callback function:_x000D_
console.log('Iterate with Array.from callback argument:');_x000D_
Array.from(document.querySelectorAll('#navbar>ul>li'),li => console.log(li.textContent))_x000D_
_x000D_
// ... or a for...of loop:_x000D_
console.log('Iterate with for...of:');_x000D_
for (const li of document.querySelectorAll('#navbar>ul>li')) {_x000D_
    console.log(li.textContent);_x000D_
}

.as-console-wrapper { max-height: 100% !important; top: 0; }

<div id="navbar">_x000D_
  <ul>_x000D_
    <li id="navbar-One">One</li>_x000D_
    <li id="navbar-Two">Two</li>_x000D_
    <li id="navbar-Three">Three</li>_x000D_
  </ul>_x000D_
</div>

You can use jOOR for that.

class Foo {
    private final String value = "ABC";
}
class Bar {
    private final Foo foo = new Foo();
    public String value() {
        return org.joor.Reflect
            .on(this.foo)
            .field("value")
            .get();
    }
}
class BarTest {
    @Test
    void accessPrivateField() {
        Assertions.assertEquals(new Bar().value(), "ABC");
    }
}

Here is a very simple answer to this.

Don't forget the two (()) 'brackets' around columns names.Otherwise, it'll give you an error.

# here you can add below line and it should work 
df = df[list(('Mid','Upper', 'Lower', 'Net','Zsore'))]

You must escape special Regex symbols in input wildcard pattern (for example pattern *.txt will equivalent to ^.*\.txt$) So slashes, braces and many special symbols must be replaced with @"\" + s, where s - special Regex symbol.

I don’t see what worked for me listed out here so I will include it should anybody be in my situation.

My situation, I have a remote repository of maybe 10,000 files and I need to build an RPM file for my Linux system. The build of the RPM includes a git clone of everything. All I need is one file to start the RPM build. I can clone the entire source tree which does what I need but it takes an extra two minutes to download all those files when all I need is one. I tried to use the git archive option discussed and I got “fatal: Operation not supported by protocol.” It seems I have to get some sort of archive option enabled on the server and my server is maintained by bureaucratic thugs that seem to enjoy making it difficult to get things done.

What I finally did was I went into the web interface for bitbucket and viewed the one file I needed. I did a right click on the link to download a raw copy of the file and selected “copy shortcut” from the resulting popup. I could not just download the raw file because I needed to automate things and I don’t have a browser interface on my Linux server.

For the sake of discussion, that resulted in the URL:

https://ourArchive.ourCompany.com/projects/ThisProject/repos/data/raw/foo/bar.spec?at=refs%2Fheads%2FTheBranchOfInterest

I could not directly download this file from the bitbucket repository because I needed to sign in first. After a little digging, I found this worked: On Linux:

echo "myUser:myPass123"| base64
bXlVc2VyOm15UGFzczEyMwo=

curl -H 'Authorization: Basic bXlVc2VyOm15UGFzczEyMwo=' 'https://ourArchive.ourCompany.com/projects/ThisProject/repos/data/raw/foo/bar.spec?at=refs%2Fheads%2FTheBranchOfInterest' > bar.spec

This combination allowed me to download the one file I needed to build everything else.

You can use a cursor and temp table approach so you aren't doing full table scan each time. What this would be doing is populating the temp table with all of your keywords, and then with each string in the @letters XML, it would remove any records from the temp table. At the end, you only have records in your temp table that have each of your desired strings in it.

declare @letters xml

SET @letters = '<letters>
            <letter>a</letter>
            <letter>b</letter>
        </letters>'

-- SELECTING LETTERS FROM THE XML
SELECT Letters.l.value('.', 'nvarchar(50)') AS letter
FROM @letters.nodes('/letters/letter') AS Letters(l)

-- CREATE A TEMP TABLE WE CAN DELETE FROM IF A RECORD DOESN'T HAVE THE LETTER
CREATE TABLE #TempResults (keywordID int not null, keyWord nvarchar(50) not null)
INSERT INTO #TempResults (keywordID, keyWord)
SELECT employeeID, firstName FROM Employee

-- CREATE A CURSOR, SO WE CAN LOOP THROUGH OUR LETTERS AND REMOVE KEYWORDS THAT DON'T MATCH
DECLARE Cursor_Letters CURSOR READ_ONLY
FOR 
    SELECT Letters.l.value('.', 'nvarchar(50)') AS letter
    FROM @letters.nodes('/letters/letter') AS Letters(l)

DECLARE @letter varchar(50)
OPEN Cursor_Letters

FETCH NEXT FROM Cursor_Letters INTO @letter
WHILE (@@fetch_status <> -1)
BEGIN
    IF (@@fetch_status <> -2)
    BEGIN
        DELETE FROM #TempResults 
        WHERE  keywordID NOT IN 
        (SELECT keywordID FROM #TempResults WHERE keyWord LIKE '%' + @letter + '%')
    END
    FETCH NEXT FROM Cursor_Letters INTO @letter
END

CLOSE Cursor_Letters
DEALLOCATE Cursor_Letters

SELECT * FROM #TempResults

DROP Table #TempResults
GO

Creating colnames with iterating

#   <thead>
#     <tr style="text-align: right;">
#       <th></th>
#       <th>colname_0</th>
#       <th>colname_1</th>
#       <th>colname_2</th>
#       <th>colname_3</th>
#       <th>colname_4</th>
#     </tr>
#   </thead>
#   <tbody>
#   </tbody>
# </table>

this seems working

print(type(df.to_html()))
# <class 'str'>

The problem is caused by

when you create df like this

df = pd.DataFrame(columns=COLUMN_NAMES)

it has 0 rows × n columns, you need to create at least one row index by

df = pd.DataFrame(columns=COLUMN_NAMES, index=[0])

now it has 1 rows × n columns. You are be able to add data. Otherwise its df that only consist colnames object(like a string list).

Let the given array be A with length N. Lets assume in the given array, the single empty slot is filled with 0.

We can find the solution for this problem using many methods including algorithm used in Counting sort. But, in terms of efficient time and space usage, we have two algorithms. One uses mainly summation, subtraction and multiplication. Another uses XOR. Mathematically both methods work fine. But programatically, we need to assess all the algorithms with main measures like

• Limitations(like input values are large(A[1...N]) and/or number of input values is large(N))
• Number of condition checks involved
• Number and type of mathematical operations involved

etc. This is because of the limitations in time and/or hardware(Hardware resource limitation) and/or software(Operating System limitation, Programming language limitation, etc), etc. Lets list and assess the pros and cons of each one of them.

Algorithm 1 :

In algorithm 1, we have 3 implementations.

1. Calculate the total sum of all the numbers(this includes the unknown missing number) by using the mathematical formula(1+2+3+...+N=(N(N+1))/2). Here, N=100. Calculate the total sum of all the given numbers. Subtract the second result from the first result will give the missing number.

   Missing Number = (N(N+1))/2) - (A[1]+A[2]+...+A[100])

2. Calculate the total sum of all the numbers(this includes the unknown missing number) by using the mathematical formula(1+2+3+...+N=(N(N+1))/2). Here, N=100. From that result, subtract each given number gives the missing number.

   Missing Number = (N(N+1))/2)-A[1]-A[2]-...-A[100]

   (Note:Even though the second implementation's formula is derived from first, from the mathematical point of view both are same. But from programming point of view both are different because the first formula is more prone to bit overflow than the second one(if the given numbers are large enough). Even though addition is faster than subtraction, the second implementation reduces the chance of bit overflow caused by addition of large values(Its not completely eliminated, because there is still very small chance since (N+1) is there in the formula). But both are equally prone to bit overflow by multiplication. The limitation is both implementations give correct result only if N(N+1)<=MAXIMUM_NUMBER_VALUE. For the first implementation, the additional limitation is it give correct result only if Sum of all given numbers<=MAXIMUM_NUMBER_VALUE.)

3. Calculate the total sum of all the numbers(this includes the unknown missing number) and subtract each given number in the same loop in parallel. This eliminates the risk of bit overflow by multiplication but prone to bit overflow by addition and subtraction.

   //ALGORITHM missingNumber = 0; foreach(index from 1 to N) { missingNumber = missingNumber + index; //Since, the empty slot is filled with 0, //this extra condition which is executed for N times is not required. //But for the sake of understanding of algorithm purpose lets put it. if (inputArray[index] != 0) missingNumber = missingNumber - inputArray[index]; }

In a programming language(like C, C++, Java, etc), if the number of bits representing a integer data type is limited, then all the above implementations are prone to bit overflow because of summation, subtraction and multiplication, resulting in wrong result in case of large input values(A[1...N]) and/or large number of input values(N).

Algorithm 2 :

We can use the property of XOR to get solution for this problem without worrying about the problem of bit overflow. And also XOR is both safer and faster than summation. We know the property of XOR that XOR of two same numbers is equal to 0(A XOR A = 0). If we calculate the XOR of all the numbers from 1 to N(this includes the unknown missing number) and then with that result, XOR all the given numbers, the common numbers get canceled out(since A XOR A=0) and in the end we get the missing number. If we don't have bit overflow problem, we can use both summation and XOR based algorithms to get the solution. But, the algorithm which uses XOR is both safer and faster than the algorithm which uses summation, subtraction and multiplication. And we can avoid the additional worries caused by summation, subtraction and multiplication.

In all the implementations of algorithm 1, we can use XOR instead of addition and subtraction.

Lets assume, XOR(1...N) = XOR of all numbers from 1 to N

Implementation 1 => Missing Number = XOR(1...N) XOR (A[1] XOR A[2] XOR...XOR A[100])

Implementation 2 => Missing Number = XOR(1...N) XOR A[1] XOR A[2] XOR...XOR A[100]

Implementation 3 =>

//ALGORITHM
missingNumber = 0;
foreach(index from 1 to N)
{
    missingNumber = missingNumber XOR index;
    //Since, the empty slot is filled with 0,
    //this extra condition which is executed for N times is not required.
    //But for the sake of understanding of algorithm purpose lets put it.
    if (inputArray[index] != 0)
        missingNumber = missingNumber XOR inputArray[index];
}

All three implementations of algorithm 2 will work fine(from programatical point of view also). One optimization is, similar to

1+2+....+N = (N(N+1))/2

We have,

1 XOR 2 XOR .... XOR N = {N if REMAINDER(N/4)=0, 1 if REMAINDER(N/4)=1, N+1 if REMAINDER(N/4)=2, 0 if REMAINDER(N/4)=3}

We can prove this by mathematical induction. So, instead of calculating the value of XOR(1...N) by XOR all the numbers from 1 to N, we can use this formula to reduce the number of XOR operations.

Also, calculating XOR(1...N) using above formula has two implementations. Implementation wise, calculating

// Thanks to https://a3nm.net/blog/xor.html for this implementation
xor = (n>>1)&1 ^ (((n&1)>0)?1:n)

is faster than calculating

xor = (n % 4 == 0) ? n : (n % 4 == 1) ? 1 : (n % 4 == 2) ? n + 1 : 0;

So, the optimized Java code is,

long n = 100;
long a[] = new long[n];

//XOR of all numbers from 1 to n
// n%4 == 0 ---> n
// n%4 == 1 ---> 1
// n%4 == 2 ---> n + 1
// n%4 == 3 ---> 0

//Slower way of implementing the formula
// long xor = (n % 4 == 0) ? n : (n % 4 == 1) ? 1 : (n % 4 == 2) ? n + 1 : 0;
//Faster way of implementing the formula
// long xor = (n>>1)&1 ^ (((n&1)>0)?1:n);
long xor = (n>>1)&1 ^ (((n&1)>0)?1:n);

for (long i = 0; i < n; i++)
{
    xor = xor ^ a[i];
}
//Missing number
System.out.println(xor);

In SQL, the way to do this is to double the apostrophe:

'he doesn''t work for me'

If you are doing this programmatically, you should use an API that accepts parameters and escapes them for you, like prepared statements or similar, rather that escaping and using string concatenation to assemble a query.

alternatively, you can try writing a specific element:

    //label[1] is the first element.
    el =  await driver.findElement(By.xpath("//div[@class=\"facetContainerDiv\"]/div/label[1]/input")));
    await el.click();

If this is C#, it won't work: enums are value types, and can't be null.

The normal options are to add a None member:

public enum Color
{
  None,
  Red,
  Green,
  Yellow
}

Color color = Color.None;

...or to use Nullable:

Color? color = null;

Data transfer between two platform requires a common data format. JSON is a common global format to send cross platform data.

drawChart(600/50, JSON.parse('<?php echo json_encode($day); ?>'), JSON.parse('<?php echo json_encode($week); ?>'), JSON.parse('<?php echo json_encode($month); ?>'), JSON.parse('<?php echo json_encode(createDatesArray(cal_days_in_month(CAL_GREGORIAN, date('m',strtotime('-1 day')), date('Y',strtotime('-1 day'))))); ?>'))

This is the answer to your question. The answer may look very complex. You can see a simple example describing the communication between server side and client side here

$employee = array(
 "employee_id" => 10011,
   "Name" => "Nathan",
   "Skills" =>
    array(
           "analyzing",
           "documentation" =>
            array(
              "desktop",
                "mobile"
             )
        )
);

Conversion to JSON format is required to send the data back to client application ie, JavaScript. PHP has a built in function json_encode(), which can convert any data to JSON format. The output of the json_encode function will be a string like this.

{
    "employee_id": 10011,
    "Name": "Nathan",
    "Skills": {
        "0": "analyzing",
        "documentation": [
            "desktop",
            "mobile"
        ]
    }
}

On the client side, success function will get the JSON string. Javascript also have JSON parsing function JSON.parse() which can convert the string back to JSON object.

$.ajax({
        type: 'POST',
        headers: {
            "cache-control": "no-cache"
        },
        url: "employee.php",
        async: false,
        cache: false,
        data: {
            employee_id: 10011
        },
        success: function (jsonString) {
            var employeeData = JSON.parse(jsonString); // employeeData variable contains employee array.
    });

First, you need to know the naming rule of lxxx:

/usr/bin/ld: cannot find -lc
/usr/bin/ld: cannot find -lltdl
/usr/bin/ld: cannot find -lXtst

lc means libc.so, lltdl means libltdl.so, lXtst means libXts.so.

So, it is lib + lib-name + .so

Once we know the name, we can use locate to find the path of this lxxx.so file.

$ locate libiconv.so
/home/user/anaconda3/lib/libiconv.so   # <-- right here
/home/user/anaconda3/lib/libiconv.so.2
/home/user/anaconda3/lib/libiconv.so.2.5.1
/home/user/anaconda3/lib/preloadable_libiconv.so
/home/user/anaconda3/pkgs/libiconv-1.14-0/lib/libiconv.so
/home/user/anaconda3/pkgs/libiconv-1.14-0/lib/libiconv.so.2
/home/user/anaconda3/pkgs/libiconv-1.14-0/lib/libiconv.so.2.5.1
/home/user/anaconda3/pkgs/libiconv-1.14-0/lib/preloadable_libiconv.so

If you cannot find it, you need to install it by yum (I use CentOS). Usually you have this file, but it does not link to right place.

Link it to the right place, usually it is /lib64 or /usr/lib64

$ sudo ln -s /home/user/anaconda3/lib/libiconv.so /usr/lib64/

Done!

If you set "Use regular expressions" flag then \n would be translated. But keep in mind that you would have to modify you search term to be regexp friendly. In your case it should be escaped like this "\~\~\?" (no quotes).

If you have a NavigationController embedded inside of a TabBarController see below:

super.tabBarController?.title = "foobar"

You can debug issues like this with debugger scripts. Try Chisel's pvc command to print every visible / hidden view on the hierarchy.

Output the images in a lossless format such as PNG:

ffmpeg.exe -i 10fps.h264 -r 10 -f image2 10fps.h264_%03d.png

Edit/Update: Not quite sure why I originally gave a strange filename example (with a possibly made-up extension).

I have since found that -vsync 0 is simpler than -r 10 because it avoids needing to know the frame rate.

This is something like what I currently use:

mkdir stills
ffmpeg -i my-film.mp4 -vsync 0 -f image2 stills/my-film-%06d.png

To extract only the key frames (which are likely to be of higher quality post-edit):

ffmpeg -skip_frame nokey -i my-film.mp4 -vsync 0 -f image2 stills/my-film-%06d.png

Then use another program (where you can more precisely specify quality, subsampling and DCT method – e.g. GIMP) to convert the PNGs you want to JPEG.

It is possible to obtain slightly sharper images in JPEG format this way than is possible with -qmin 1 -q:v 1 and outputting as JPEG directly from ffmpeg.

Maybe .text instead of .html?

I ended up using the bootstrap 3 dropdown button, I'm posting my solution here in case it helps someone in future. Adding the bootstrap 3 list-inline to the class for the ul causes it to display in a nicely compact format as well.

<div class="btn-group">
    <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
        Select icon <span class="caret"></span>
    </button>
    <ul class="dropdown-menu list-inline" role="menu">
        <li><span class="glyphicon glyphicon-cutlery"></span></li>
        <li><span class="glyphicon glyphicon-fire"></span></li>
        <li><span class="glyphicon glyphicon-glass"></span></li>
        <li><span class="glyphicon glyphicon-heart"></span></li>          
    </ul>
</div>

I'm using Angular.js so this is the actual code I used:

<div class="btn-group">
            <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
                Avatar <span class="caret"></span>
            </button>
            <ul class="dropdown-menu list-inline" role="menu">
                <li ng-repeat="avatar in avatars" ng-click="avatarSelected(avatar)">
                    <span ng-class="getAvatar(avatar)"></span>
                </li>
            </ul>
        </div>

And in my controller:

$scope.avatars=['cutlery','eye-open','flag','flash','glass','fire','hand-right','heart','heart-empty','leaf','music','send','star','star-empty','tint','tower','tree-conifer','tree-deciduous','usd','user','wrench','time','road','cloud'];

$scope.getAvatar=function(avatar){
     return 'glyphicon glyphicon-'+avatar;
};

Rank() SQL function generates rank of the data within ordered set of values but next rank after previous rank is row_number of that particular row. On the other hand, Dense_Rank() SQL function generates next number instead of generating row_number. Below is the SQL example which will clarify the concept:

Select ROW_NUMBER() over (order by Salary) as RowNum, Salary, 
RANK() over (order by Salary) as Rnk, 
DENSE_RANK() over (order by Salary) as DenseRnk from (
Select 1000 as Salary union all
Select 1000 as Salary union all
Select 1000 as Salary union all
Select 2000 as Salary union all
Select 3000 as Salary union all
Select 3000 as Salary union all
Select 8000 as Salary union all
Select 9000 as Salary) A

It will generate following output:

----------------------------
RowNum  Salary  Rnk DenseRnk
----------------------------
1       1000    1   1
2       1000    1   1
3       1000    1   1
4       2000    4   2
5       3000    5   3
6       3000    5   3
7       8000    7   4
8       9000    8   5

Following commands works:

npm install
ng update

-You may see the message "We analyzed your package.json and everything seems to be in order. Good work!"

npm update

Then try dev build

ng build 

I got the error with type script, downgraded to

npm install typescript@">=3.1.1 <3.2

ng build --prod 

All success with prod build.

Below is the working combination

ng --version

TCP / HTTP Listening On Ports: How Can Many Users Share the Same Port

So, what happens when a server listen for incoming connections on a TCP port? For example, let's say you have a web-server on port 80. Let's assume that your computer has the public IP address of 24.14.181.229 and the person that tries to connect to you has IP address 10.1.2.3. This person can connect to you by opening a TCP socket to 24.14.181.229:80. Simple enough.

Intuitively (and wrongly), most people assume that it looks something like this:

    Local Computer    | Remote Computer
    --------------------------------
    <local_ip>:80     | <foreign_ip>:80

    ^^ not actually what happens, but this is the conceptual model a lot of people have in mind.

This is intuitive, because from the standpoint of the client, he has an IP address, and connects to a server at IP:PORT. Since the client connects to port 80, then his port must be 80 too? This is a sensible thing to think, but actually not what happens. If that were to be correct, we could only serve one user per foreign IP address. Once a remote computer connects, then he would hog the port 80 to port 80 connection, and no one else could connect.

Three things must be understood:

1.) On a server, a process is listening on a port. Once it gets a connection, it hands it off to another thread. The communication never hogs the listening port.

2.) Connections are uniquely identified by the OS by the following 5-tuple: (local-IP, local-port, remote-IP, remote-port, protocol). If any element in the tuple is different, then this is a completely independent connection.

3.) When a client connects to a server, it picks a random, unused high-order source port. This way, a single client can have up to ~64k connections to the server for the same destination port.

So, this is really what gets created when a client connects to a server:

    Local Computer   | Remote Computer           | Role
    -----------------------------------------------------------
    0.0.0.0:80       | <none>                    | LISTENING
    127.0.0.1:80     | 10.1.2.3:<random_port>    | ESTABLISHED

Looking at What Actually Happens

First, let's use netstat to see what is happening on this computer. We will use port 500 instead of 80 (because a whole bunch of stuff is happening on port 80 as it is a common port, but functionally it does not make a difference).

    netstat -atnp | grep -i ":500 "

As expected, the output is blank. Now let's start a web server:

    sudo python3 -m http.server 500

Now, here is the output of running netstat again:

    Proto Recv-Q Send-Q Local Address           Foreign Address         State  
    tcp        0      0 0.0.0.0:500             0.0.0.0:*               LISTEN      - 

So now there is one process that is actively listening (State: LISTEN) on port 500. The local address is 0.0.0.0, which is code for "listening for all". An easy mistake to make is to listen on address 127.0.0.1, which will only accept connections from the current computer. So this is not a connection, this just means that a process requested to bind() to port IP, and that process is responsible for handling all connections to that port. This hints to the limitation that there can only be one process per computer listening on a port (there are ways to get around that using multiplexing, but this is a much more complicated topic). If a web-server is listening on port 80, it cannot share that port with other web-servers.

So now, let's connect a user to our machine:

    quicknet -m tcp -t localhost:500 -p Test payload.

This is a simple script (https://github.com/grokit/dcore/tree/master/apps/quicknet) that opens a TCP socket, sends the payload ("Test payload." in this case), waits a few seconds and disconnects. Doing netstat again while this is happening displays the following:

    Proto Recv-Q Send-Q Local Address           Foreign Address         State  
    tcp        0      0 0.0.0.0:500             0.0.0.0:*               LISTEN      -
    tcp        0      0 192.168.1.10:500        192.168.1.13:54240      ESTABLISHED -

If you connect with another client and do netstat again, you will see the following:

    Proto Recv-Q Send-Q Local Address           Foreign Address         State  
    tcp        0      0 0.0.0.0:500             0.0.0.0:*               LISTEN      -
    tcp        0      0 192.168.1.10:500        192.168.1.13:26813      ESTABLISHED -

... that is, the client used another random port for the connection. So there is never confusion between the IP addresses.

For people (like me) looking for an answer for special characters like Ä etc. just use this pattern:

• Only text (or a space): "[A-Za-zÀ-? ]"

• Text and numbers: "[A-Za-zÀ-?0-9 ]"

• Text, numbers and some special chars: "[A-Za-zÀ-?0-9(),-_., ]"

Regex just starts at the ascii index and checks if a character of the string is in within both indexes [startindex-endindex].

So you can add any range.

Eventually you can play around with a handy tool: https://regexr.com/

Good luck;)

Swift 4.2 / 5

override func viewDidLoad() {
    super.viewDidLoad()
    NotificationCenter.default.addObserver(self, selector: #selector(willEnterForeground),
                                           name: Notification.Name.UIApplicationWillEnterForeground,
                                           object: nil)
}

@objc func willEnterForeground() {
   // do what's needed
}

Try the -i flag (or --ignore-errors). The documentation seems to suggest a more robust way to achieve this, by the way:

To ignore errors in a command line, write a - at the beginning of the line's text (after the initial tab). The - is discarded before the command is passed to the shell for execution.

For example,

clean:
  -rm -f *.o

This causes rm to continue even if it is unable to remove a file.

All examples are with rm, but are applicable to any other command you need to ignore errors from (i.e. mkdir).

You have to provide the full path that you want to import.

import com.my.stuff.main.Main;
import com.my.stuff.second.*;

So, in your main class, you'd have:

package com.my.stuff.main

import com.my.stuff.second.Second;   // THIS IS THE IMPORTANT LINE FOR YOUR QUESTION

class Main {
   public static void main(String[] args) {
      Second second = new Second();
      second.x();  
   }
}

EDIT: adding example in response to Shawn D's comment

There is another alternative, as Shawn D points out, where you can specify the full package name of the object that you want to use. This is very useful in two locations. First, if you're using the class exactly once:

class Main {
    void function() {
        int x = my.package.heirarchy.Foo.aStaticMethod();

        another.package.heirarchy.Baz b = new another.package.heirarchy.Bax();
    }
}

Alternatively, this is useful when you want to differentiate between two classes with the same short name:

class Main {
    void function() {
        java.util.Date utilDate = ...;
        java.sql.Date sqlDate = ...;
    }
}

Without knowing your compiler, no one can give you specific, step by step instructions, but the basic procedure is as follows:

1. Specify the path which should be searched in order to find the actual library (usually under Library Search Paths, Library Directories, etc. in the properties page)

2. Under linker options, specify the actual name of the library. In VS, you would write Allegro.lib (or whatever it is), on Linux you usually just write Allegro (prefixes/suffixes are added automatically in most cases). This is usually under "Libraries->Input", just "Libraries", or something similar.

3. Ensure that you have included the headers for the library and make sure that they can be found (similar process to that listed in step #1 and #2). If it is a static library, you should be good; if it's a DLL, you need to copy it in your project.

4. Mash the build button.

You can try adding action="#{yourBean.function1}" on each button (changing of course the method function2, function3, or whatever you need). If that does not work, you can try the same with the onclick event.

Anyway, it would be easier to help you if you tell us what kind of buttons are you trying to use, a4j:commandButton or whatever you are using.

Add this code before the HttpsURLConnection and it will be done. I got it.

                    public boolean verify(String hostname, SSLSession session) { 
                            return true; 
                    }}); 
            SSLContext context = SSLContext.getInstance("TLS"); 
            context.init(null, new X509TrustManager[]{new X509TrustManager(){ 
                    public void checkClientTrusted(X509Certificate[] chain, 
                                    String authType) throws CertificateException {} 
                    public void checkServerTrusted(X509Certificate[] chain, 
                                    String authType) throws CertificateException {} 
                    public X509Certificate[] getAcceptedIssuers() { 
                            return new X509Certificate[0]; 
                    }}}, new SecureRandom()); 
            HttpsURLConnection.setDefaultSSLSocketFactory( 
                            context.getSocketFactory()); 
    } catch (Exception e) { // should never happen 
            e.printStackTrace(); 
    } 
}

In my case I was using a different account, I created an app on Itunes but selected different account on Xcode. So just Selected the right account on Xcode and it worked for me.

This error will occur if the configuration file of the hosting application of your WCF service does not have the proper configuration.

Remember this comment from configuration:

When deploying the service library project, the content of the config file must be added to the host's app.config file. System.Configuration does not support config files for libraries.

If you have a WCF Service hosted in IIS, during runtime via VS.NET it will read the app.config of the service library project, but read the host's web.config once deployed. If web.config does not have the identical <system.serviceModel> configuration you will receive this error. Make sure to copy over the configuration from app.config once it has been perfected.

In v3 of Bootstrap there is a simple method to make a modal larger. Just add the class modal-lg next to modal-dialog.

<!-- My Modal Popup -->
<div id="MyWidePopup" class="modal fade" role="dialog">
    <div class="modal-dialog modal-lg"> <---------------------RIGHT HERE!!
        <!-- Modal content-->
        <div class="modal-content">

Selecting is often unnecessary. Try this

Sub OneCell()
    Sheets("Sheet2").range("B1:B3").value = Sheets("Sheet1").range("A1:A3").value
End Sub

The top answer is the best! However, it was not triggering mouse events for me in Firefox when etype = 'click'.

So, I changed the document.createEvent to 'MouseEvents' and that fixed the problem. The extra code is to test whether or not another bit of code was interfering with the event, and if it was cancelled I would log that to console.

function eventFire(el, etype){
  if (el.fireEvent) {
    el.fireEvent('on' + etype);
  } else {
    var evObj = document.createEvent('MouseEvents');
    evObj.initEvent(etype, true, false);
    var canceled = !el.dispatchEvent(evObj);
    if (canceled) {
      // A handler called preventDefault.
      console.log("automatic click canceled");
    } else {
      // None of the handlers called preventDefault.
    } 
  }
}

The .pid is the processid of the running mysql server instance. It appears in the data folder when mysql is running and removes itself when mysql is shutdown.

If the OSX operating system is upgraded and mysql is not shutdown properly before the upgrade,mysql quits when it started up it just quits because of the .pid file.

There are a few tricks you can try, http://coolestguidesontheplanet.com/mysql-error-server-quit-without-updating-pid-file/ failing these a reinstall is needed.

I use this for Automatic column hiding as per column data, in that case, sometimes its break table structure. i solve that problem with this $($.fn.dataTable.tables(true)).DataTable().columns.adjust(); and this function $('#datatableId').on('draw.dt', function () { }); call after tabledata load.

$('#datatableId').on('draw.dt', function () {
    $($.fn.dataTable.tables(true)).DataTable().columns.adjust();
})

This is the way I just did on Android Studio version 1.0.2

• I have created a folder libs in [your project dir]\app\src
• I have copied the jtwitter.jar (or the yambaclientlib.jar) into the [your project dir]\app\src\libs directory
• The following the menu path: File -> Project Structure -> Dependencies -> Add -> File Dependency, Android Studio opens a dialog box where you can drag&drop the jar library. Then I clicked the OK button.

At this point Gradle will rebuild the project importing the library and resolving the dependencies.

Response.Write("<script>alert('Data inserted successfully')</script>");

in AndroidManifest.xml set theme holo like this:

<activity
android:name="your Fragment or activity"
android:label="@string/xxxxxx"
android:theme="@android:style/Theme.Holo" >

$bucket = '$node->' . $fieldname . "['und'][0]['value'] = " . '$form_state' . "['values']['" . $fieldname . "']";

print $bucket;

yields:

$node->mindd_2_study_status['und'][0]['value'] = $form_state['values']
['mindd_2_study_status']

Try the following code:

SELECT *
FROM users
WHERE firstname IN ('joe','jane');

Use file module to create a directory and get the details about file module using command "ansible-doc file"

Here is an option "state" that explains:

If directory, all immediate subdirectories will be created if they do not exist, since 1.7 they will be created with the supplied permissions.
If file, the file will NOT be created if it does not exist, see the [copy] or [template] module if you want that behavior.
If link, the symbolic link will be created or changed. Use hard for hardlinks.
If absent, directories will be recursively deleted, and files or symlinks will be unlinked.

Note that file will not fail if the path does not exist as the state did not change.

If touch (new in 1.4), an empty file will be created if the path does not exist, while an existing file or directory will receive updated file access and modification times (similar to the way touch works from the command line).

to set Oracle's Java SE Development Kit as the system default Java just download the latest Java SE Development Kit from here then create a directory somewhere you like in your file system for example /usr/java now extract the files you just downloaded in that directory:

$ sudo tar xvzf jdk-8u5-linux-i586.tar.gz -C /usr/java

now to set your JAVA_HOME environment variable:

$ JAVA_HOME=/usr/java/jdk1.8.0_05/
$ sudo update-alternatives --install /usr/bin/java java ${JAVA_HOME%*/}/bin/java 20000
$ sudo update-alternatives --install /usr/bin/javac javac ${JAVA_HOME%*/}/bin/javac 20000

make sure the Oracle's java is set as default java by:

$ update-alternatives --config java

you get something like this:

There are 2 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                           Priority   Status
------------------------------------------------------------
* 0            /opt/java/jdk1.8.0_05/bin/java                  20000     auto mode
  1            /opt/java/jdk1.8.0_05/bin/java                  20000     manual mode
  2            /usr/lib/jvm/java-6-openjdk-i386/jre/bin/java   1061      manual mode

Press enter to keep the current choice[*], or type selection number:

pay attention to the asterisk before the numbers on the left and if the correct one is not set choose the correct one by typing the number of it and pressing enter. now test your java:

$ java -version

if you get something like the following, you are good to go:

java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) Server VM (build 25.5-b02, mixed mode)

also note that you might need root permission or be in sudoers group to be able to do this. I've tested this solution on both ubuntu 12.04 and Debian wheezy and it works in both of them.

You can also check for bootstrap datatable plugin as well for above issue.

It will have a large column table scrollable feature with lot of other options

$(document).ready(function() {
    $('#example').dataTable( {
        "scrollX": true
    } );
} );

for more info with example please check out this link

YAML follows indentation structure very strictly. Even one space/tab can cause above issue. In my case it was just once space at the start.

So make sure no extra spaces/tabs are introduced while updating YAML file

After hours of research this solution worked for me:

(disclaimer: results may vary due to circumstances)

the Library not found -lPods-(someCocoapod) error was due to multiple entries in the :

Settings(Target) > Build Settings > Linking > 'Other Linker Flags'

A lot of other posts had me look there and I would see changes to the error when I messed around with the entries, but I kept getting some variation on the same error.

Too many hours lost ...

My Fix:

remove the -lPods-(someCocoaPod) lines in the 'Other Linker Flags' list BUT only if $(inherited) is at the top. At first I was unsure, but the reassuring sign was that I still saw references to my cocoapods when I left the edit mode(inherited). I tested in debug and release, both of which were giving me errors, and the problem was immediately resolved.

One can invoke mysqldump locally against a remote server.

Example that worked for me:

mysqldump -h hostname-of-the-server -u mysql_user -p database_name > file.sql

I followed the mysqldump documentation on connection options.

The only reason I'd say for(;;) is due the CodeDom limitations (while loops can't be declared using CodeDom and for loops are seen as the more general form as an iteration loop).

This is a pretty loose reason to choose this other than the fact that the for loop implementation can be used both for normal code and CodeDom generated code. That is, it can be more standard.

As a note, you can use code snippets to create a while loop, but the whole loop would need to be a snippet...

You can also use:

map.setView(new L.LatLng(40.737, -73.923), 8);

It just depends on what behavior you want. map.panTo() will pan to the location with zoom/pan animation, while map.setView() immediately set the new view to the desired location/zoom level.

You can do this by using properties of textfield from Attribute inspector

Tap on Your Textfield from storyboard and go to Attribute inspector , and just check the checkbox of "Secure Text Entry" SS is added for graphical overview to achieve same

Echo is so nineties and so fraught with perils that its use should result in core dumps no less than 4GB. Seriously, echo's problems were the reason why the Unix Standardization process finally invented the printf utility, doing away with all the problems.

So to get a newline in a string:

FOO="hello
world"
BAR=$(printf "hello\nworld\n") # Alternative; note: final newline is deleted
printf '<%s>\n' "$FOO"
printf '<%s>\n' "$BAR"

There! No SYSV vs BSD echo madness, everything gets neatly printed and fully portable support for C escape sequences. Everybody please use printf now and never look back.

In my case I had a prefix that had to be added for each route in the group, otherwise response would be that the UserController class was not found.

Route::prefix('/user')->group(function() {
    Route::post('/login', [UserController::class, 'login'])->prefix('/user');
    Route::post('/register', [UserController::class, 'register'])->prefix('/user');
});

You need to ensure that any code that modifies the HTTP headers is executed before the headers are sent. This includes statements like session_start(). The headers will be sent automatically when any HTML is output.

Your problem here is that you're sending the HTML ouput at the top of your page before you've executed any PHP at all.

Move the session_start() to the top of your document :

<?php    session_start(); ?> <html> <head> <title>PHP SDK</title> </head> <body> <?php require_once 'src/facebook.php';    // more PHP code here. 

You can actually do what Chris Chalmers does in his answer, but you must make sure that HAML doesn't parse the JavaScript. This approach is actually useful when you need to use a different type than text/javascript, which is was I needed to do for MathJax.

You can use the plain filter to keep HAML from parsing the script and throwing an illegal nesting error:

%script{type: "text/x-mathjax-config"}
  :plain
    MathJax.Hub.Config({
      tex2jax: {
        inlineMath: [["$","$"],["\\(","\\)"]]
      }
    });

To clone git repository into a specific folder, you can use -C <path> parameter, e.g.

git -C /httpdocs clone [email protected]:whatever

Although it'll still create a whatever folder on top of it, so to clone the content of the repository into current directory, use the following syntax:

cd /httpdocs
git clone [email protected]:whatever .

^{Note that cloning into an existing directory is only allowed when the directory is empty.}

Since you're cloning into folder that is accessible for public, consider separating your Git repository from your working tree by using --separate-git-dir=<git dir> or exclude .git folder in your web server configuration (e.g. in .htaccess file).

It is strange, that no one yet has suggested the most robust way of closing a feature branches... You can just combine merge commit with --close-branch flag (i.e. commit modified files and close the branch simultaneously):

hg up feature-x
hg merge default
hg ci -m "Merge feature-x and close branch" --close-branch
hg branch default -f

So, that is all. No one extra head on revgraph. No extra commit.

With the latest release of Bootstrap RC 3, changing the color of the icons is as simple as adding a class with the color you want and adding it to the span.

Default black color:

<h1>Password Changed <span class="glyphicon glyphicon-ok"></span></h1>

would become

<h1>Password Changed <span class="glyphicon glyphicon-ok icon-success"></span></h1>

CSS

.icon-success {
    color: #5CB85C;
}

It seems odd that this directory was not created at install - have you manually changed the path of the socket file in the my.cfg?

Have you tried simply creating this directory yourself, and restarting the service?

I like the top-voted answer by Dan McNevin. I ended up doing the sequence of git commands too many times and decided to make a script. So here it is:

#!/bin/bash

usage() {
    echo "Usage: ${0} -m [ master-branch-directory ] -r [ remote-branch-directory ] [ project-name ]"
    exit 1
}

defaults() {
    masterdir="${HOME}/Dropbox/git"
    remotedir="${PWD}"
    gitignorefile="# OS generated files #\n\n.DS_Store\n.DS_Store?\n.Spotlight-V100\n.Trashes\nehthumbs.db\nThumbs.db"
}

# Check if no arguments
if [ ${#} -eq 0 ] ; then
    echo "Error: No arguments specified"
    usage
fi

#Set defaults
defaults

# Parse arguments
while [ ${#} -ge 1 ]; do
    case "${1}" in
        '-h' | '--help' ) usage ;;
        '-m' )
            shift
            masterdir="${1}"
            ;;
        '-r' )
            shift
            remotedir="${1}"
            ;;
        * )
            projectname="${1##*/}"
            projectname="${projectname%.git}.git"
            ;;
    esac
    shift
done

# check if specified directories and project name exists
if [ -z "${projectname}" ]; then
    echo "Error: Project name not specified"
    usage
fi

if [ ! -d "${remotedir}" ]; then
    echo "Error: Remote directory ${remotedir} does not exist"
    usage
fi

if [ ! -d "${masterdir}" ]; then
    echo "Error: Master directory ${masterdir} does not exist"
    usage

#absolute paths

#Make master git repository
cd "${masterdir}"
git init --bare "${projectname}"

#make local repository and push to master
cd "${remotedir}"
echo -e "${gitignorefile}" > .gitignore # default .gitignore file

git push -u origin master

#done
echo "----- Locations -----"
echo "Remote branch location: ${remotedir}"
echo "Master branch location: ${masterdir}"
echo "Project Name: ${projectname}"

The script only requires a project name. It will generate a git repository in ~/Dropbox/git/ under the specified name and will push the entire contents of the current directory to the newly created origin master branch. If more than one project name is given, the right-most project name argument will be used.

Optionally, the -r command argument specifies the remote branch that will push to the origin master. The location of the project origin master can also be specified with the -m argument. A default .gitignore file is also placed in the remote branch directory. The directory and .gitignore file defaults are specified in the script.

SQLite has had to sacrifice other characteristics that some people find useful, such as high concurrency, fine-grained access control, a rich set of built-in functions, stored procedures, esoteric SQL language features, XML and/or Java extensions, tera- or peta-byte scalability, and so forth

Source : Appropriate Uses For SQLite

If you are using numpy, the closest, I can think of is using a mask

>>> import numpy as np
>>> arr = np.arange(1,10)
>>> mask = np.ones(arr.shape,dtype=bool)
>>> mask[5]=0
>>> arr[mask]
array([1, 2, 3, 4, 5, 7, 8, 9])

Something similar can be achieved using itertools without numpy

>>> from itertools import compress
>>> arr = range(1,10)
>>> mask = [1]*len(arr)
>>> mask[5]=0
>>> list(compress(arr,mask))
[1, 2, 3, 4, 5, 7, 8, 9]

Even if you write a regular expression that matches exactly the subset "valid phone numbers" out of strings, there is no way to guarantee (by way of a regular expression) that they are valid mobile phone numbers. In several countries, mobile phone numbers are indistinguishable from landline phone numbers without at least a number plan lookup, and in some cases, even that won't help. For example, in Sweden, lots of people have "ported" their regular, landline-like phone number to their mobile phone. It's still the same number as they had before, but now it goes to a mobile phone instead of a landline.

Since valid phone numbers consist only of digits, I doubt that rolling your own would risk missing some obscure case of phone number at least. If you want to have better certainty, write a generator that takes a list of all valid country codes, and requires one of them at the beginning of the phone number to be matched by the generated regular expression.

You could delete all the rows from all tables using an approach like Rubens suggested, or you could just drop and recreate all the tables. Always a good idea to have the full db creation scripts anyway so that may be the easiest/quickest method.

There are multiple solutions depending on the entity attribute type.

Basic attributes

Consider you have the following account table:

The account table is mapped to the Account entity like this:

@Entity(name = "Account")
public class Account {

    @Id
    private Long id;

    @ManyToOne
    private User owner;

    private String iban;

    private long cents;

    private double interestRate;

    private Timestamp createdOn;

    @Transient
    private double dollars;

    @Transient
    private long interestCents;

    @Transient
    private double interestDollars;

    @PostLoad
    private void postLoad() {
        this.dollars = cents / 100D;

        long months = createdOn.toLocalDateTime()
            .until(LocalDateTime.now(), ChronoUnit.MONTHS);
        double interestUnrounded = ( ( interestRate / 100D ) * cents * months ) / 12;
        this.interestCents = BigDecimal.valueOf(interestUnrounded)
            .setScale(0, BigDecimal.ROUND_HALF_EVEN).longValue();

        this.interestDollars = interestCents / 100D;
    }

    //Getters and setters omitted for brevity
}

The basic entity attributes are mapped to table columns, so properties like id, iban, cents are basic attributes.

But the dollars, interestCents, and interestDollars are computed properties, so you annotate them with @Transient to exclude them from SELECT, INSERT, UPDATE, and DELETE SQL statements.

So, for basic attributes, you need to use @Transient in order to exclude a given property from being persisted.

Associations

Assuming you have the following post and post_comment tables:

You want to map the latestComment association in the Post entity to the latest PostComment entity that was added.

To do that, you can use the @JoinFormula annotation:

@Entity(name = "Post")
@Table(name = "post")
public class Post {
 
    @Id
    private Long id;
 
    private String title;
 
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinFormula("(" +
        "SELECT pc.id " +
        "FROM post_comment pc " +
        "WHERE pc.post_id = id " +
        "ORDER BY pc.created_on DESC " +
        "LIMIT 1" +
    ")")
    private PostComment latestComment;
 
    //Getters and setters omitted for brevity
}

When fetching the Post entity, you can see that the latestComment is fetched, but if you want to modify it, the change is going to be ignored.

So, for associations, you can use @JoinFormula to ignore the write operations while still allowing reading the association.

@MapsId

Another way to ignore associations that are already mapped by the entity identifier is to use @MapsId.

For instance, consider the following one-to-one table relationship:

The PostDetails entity is mapped like this:

@Entity(name = "PostDetails")
@Table(name = "post_details")
public class PostDetails {
 
    @Id
    private Long id;
 
    @Column(name = "created_on")
    private Date createdOn;
 
    @Column(name = "created_by")
    private String createdBy;
 
    @OneToOne(fetch = FetchType.LAZY)
    @MapsId
    private Post post;
 
    public PostDetails() {}
 
    public PostDetails(String createdBy) {
        createdOn = new Date();
        this.createdBy = createdBy;
    }
 
    //Getters and setters omitted for brevity
}

Notice that both the id attribute and the post association map the same database column, which is the post_details Primary Key column.

To exclude the id attribute, the @MapsId annotation will tell Hibernate that the post association takes care of the table Primary Key column value.

So, when the entity identifier and an association share the same column, you can use @MapsId to ignore the entity identifier attribute and use the association instead.

Using insertable = false, updatable = false

Another option is to use insertable = false, updatable = false for the association which you want to be ignored by Hibernate.

For instance, we can map the previous one-to-one association like this:

@Entity(name = "PostDetails")
@Table(name = "post_details")
public class PostDetails {

    @Id
    @Column(name = "post_id")
    private Long id;

    @Column(name = "created_on")
    private Date createdOn;

    @Column(name = "created_by")
    private String createdBy;

    @OneToOne
    @JoinColumn(name = "post_id", insertable = false, updatable = false)
    private Post post;

    //Getters and setters omitted for brevity

    public void setPost(Post post) {
        this.post = post;
        if (post != null) {
            this.id = post.getId();
        }
    }
}

The insertable and updatable attributes of the @JoinColumn annotation will instruct Hibernate to ignore the post association since the entity identifier takes care of the post_id Primary Key column.

Just Javascript (as requested)

Add this function somewhere on your page (preferably in the <head>)

function clearBox(elementID)
{
    document.getElementById(elementID).innerHTML = "";
}

Then add the button on click event:

<button onclick="clearBox('cart_item')" />

In JQuery (for reference)

If you prefer JQuery you could do:

$("#cart_item").html("");

Are you specifically trying to rotate the links only? Because doing it on the LI tags seems to work fine.

According to Snook transforms require the elements affected be block. He's also got some code there to make this work for IE using filters, if you care to add it on(though there appears to be some limitation on values).

You also need to set the option CURLOPT_COOKIEFILE.

The manual describes this as

The name of the file containing the cookie data. The cookie file can be in Netscape format, or just plain HTTP-style headers dumped into a file. If the name is an empty string, no cookies are loaded, but cookie handling is still enabled.

Since you are using the cookie jar you end up saving the cookies when the requests finish, but since the CURLOPT_COOKIEFILE is not given, cURL isn't sending any of the saved cookies on subsequent requests.

This is an old question but the topic is very important and always current. In case anyone wants to go beyond simple getters/setters i have wrote an article about superpowered properties in python with support for slots, observability and reduced boilerplate code.

from objects import properties, self_properties


class Car:
    with properties(locals(), 'meta') as meta:

        @meta.prop(read_only=True)
        def brand(self) -> str:
            """Brand"""

        @meta.prop(read_only=True)
        def max_speed(self) -> float:
            """Maximum car speed"""

        @meta.prop(listener='_on_acceleration')
        def speed(self) -> float:
            """Speed of the car"""
            return 0  # Default stopped

        @meta.prop(listener='_on_off_listener')
        def on(self) -> bool:
            """Engine state"""
            return False

    def __init__(self, brand: str, max_speed: float = 200):
        self_properties(self, locals())

    def _on_off_listener(self, prop, old, on):
        if on:
            print(f"{self.brand} Turned on, Runnnnnn")
        else:
            self._speed = 0
            print(f"{self.brand} Turned off.")

    def _on_acceleration(self, prop, old, speed):
        if self.on:
            if speed > self.max_speed:
                print(f"{self.brand} {speed}km/h Bang! Engine exploded!")
                self.on = False
            else:
                print(f"{self.brand} New speed: {speed}km/h")
        else:
            print(f"{self.brand} Car is off, no speed change")

This class can be used like this:

mycar = Car('Ford')

# Car is turned off
for speed in range(0, 300, 50):
    mycar.speed = speed

# Car is turned on
mycar.on = True
for speed in range(0, 350, 50):
    mycar.speed = speed

This code will produce the following output:

Ford Car is off, no speed change
Ford Car is off, no speed change
Ford Car is off, no speed change
Ford Car is off, no speed change
Ford Car is off, no speed change
Ford Car is off, no speed change
Ford Turned on, Runnnnnn
Ford New speed: 0km/h
Ford New speed: 50km/h
Ford New speed: 100km/h
Ford New speed: 150km/h
Ford New speed: 200km/h
Ford 250km/h Bang! Engine exploded!
Ford Turned off.
Ford Car is off, no speed change

You do

printf ("Hi %s,</br />", $name);

before setting the cookies, which isn't allowed. You can't send any output before the headers, not even a blank line.

This should be shorter:

<font color='red'>test blue color font</font>

I had a similar problem and google was sending me to this post. My solution was a bit different and less compact, but hopefully this can be useful to someone.

Showing your image with matplotlib.pyplot.imshow is generally a fast way to display 2D data. However this by default labels the axes with the pixel count. If the 2D data you are plotting corresponds to some uniform grid defined by arrays x and y, then you can use matplotlib.pyplot.xticks and matplotlib.pyplot.yticks to label the x and y axes using the values in those arrays. These will associate some labels, corresponding to the actual grid data, to the pixel counts on the axes. And doing this is much faster than using something like pcolor for example.

Here is an attempt at this with your data:

import matplotlib.pyplot as plt

# ... define 2D array hist as you did

plt.imshow(hist, cmap='Reds')
x = np.arange(80,122,2) # the grid to which your data corresponds
nx = x.shape[0]
no_labels = 7 # how many labels to see on axis x
step_x = int(nx / (no_labels - 1)) # step between consecutive labels
x_positions = np.arange(0,nx,step_x) # pixel count at label position
x_labels = x[::step_x] # labels you want to see
plt.xticks(x_positions, x_labels)
# in principle you can do the same for y, but it is not necessary in your case

Enumerable.Repeat(String.Empty, count).ToArray()

Will create array of empty strings repeated 'count' times. In case you want to initialize array with same yet special default element value. Careful with reference types, all elements will refer same object.

Since Angular version 6 .angular-cli.json is deprecated. That file was replaced by angular.json file which supports workspaces.

I found this post very helpful as I needed to investigate dependencies from a 3rd party supplied library (32 vs 64 bit execution path(s)).

I put together a Q&D recursing bash script based on the 'readelf -d' suggestion on a RHEL 6 distro.

It is very basic and will test every dependency every time even if it might have been tested before (i.e very verbose). Output is very basic too.

#! /bin/bash

recurse ()
# Param 1 is the nuumber of spaces that the output will be prepended with
# Param 2 full path to library
{
#Use 'readelf -d' to find dependencies
dependencies=$(readelf -d ${2} | grep NEEDED | awk '{ print $5 }' | tr -d '[]')
for d in $dependencies; do
   echo "${1}${d}"
   nm=${d##*/}
   #libstdc++ hack for the '+'-s
   nm1=${nm//"+"/"\+"}
   # /lib /lib64 /usr/lib and /usr/lib are searched
   children=$(locate ${d} | grep -E "(^/(lib|lib64|usr/lib|usr/lib64)/${nm1})")
   rc=$?
   #at least locate... didn't fail
   if [ ${rc} == "0" ] ; then
      #we have at least one dependency
      if [ ${#children[@]} -gt 0 ]; then
         #check the dependeny's dependencies
         for c in $children; do
          recurse "  ${1}" ${c}
         done
      else
         echo "${1}no children found"
      fi
   else
      echo "${1}locate failed for ${d}"
   fi
done
}
# Q&D -- recurse needs 2 params could/should be supplied from cmdline
recurse "" !!full path to library you want to investigate!!

redirect the output to a file and grep for 'found' or 'failed'

It's true, they are both - or more precisely, they are "inline block" elements. This means that they flow inline like text, but also have a width and height like block elements.

In CSS, you can set an element to display: inline-block to make it replicate the behaviour of images*.

Images and objects are also known as "replaced" elements, since they do not have content per se, the element is essentially replaced by binary data.

* Note that browsers technically use display: inline (as seen in the developer tools) but they are giving special treatment to images. They still follow all traits of inline-block.

I'm not sure about the issue for making the top level anchor element a clickable anchor but here's the simplest solution for making desktop views have the hover effect, and mobile views maintaining their click-ability.

// Medium screens and up only
@media only screen and (min-width: $screen-md-min) {
    // Enable menu hover for bootstrap
    // dropdown menus
    .dropdown:hover .dropdown-menu {
        display: block;
    }
}

This way the mobile menu still behaves as it should, while the desktop menu will expand on hover instead of on a click.

I found a somewhat hacky, annoying and not-completely-sure-it-always-works solution to this. I wanted to share in case someone else finds it useful.

In Android Studio, you can right-click a class with a main method and select "Run .main()". This will create a new Run configuration for YourClass, although it won't quite work: it will be missing some classpath entries.

In order to fix the missing classpath entries, go into the Project Structure and manually add the output folder location for your module and any other module dependencies that you need, like so:

• File -> Project Structure ...
• Select "Modules" in the Project Settings panel on the left-column panel
• Select your module on the list of modules in the middle-column panel
• Select the "Dependencies" tab on the right-column panel

And then for the module where you have your Java application as well as for each of the module dependencies you need: - Click "+" -> "Jars or directories" on the far right of the right-column panel - Navigate to the output folder of the module (e.g.: my_module/build/classes/main/java) and click "OK" - On the new entry to the Dependencies list, on the far right, change the select box from "Compile" to "Runtime"

After this, you should be able to execute the Run configuration you just created to run the simple Java application.

One thing to note is that, for my particular [quite involved] Android Studio project set-up, I have to manually build the project with gradle, from outside Android Studio in order to get my simple Java Application classes to build, before I run the application - I think this is because the Run configuration of type "Application" is not triggering the corresponding Gradle build.

Finally, this was done on Android Studio 0.4.0.

I hope others find it useful. I also hope Google comes around to supporting this functionality soon.

To get the Color from Hex.

using System.Windows.Media;

Color color = (Color)ColorConverter.ConvertFromString("#FFDFD991");

and then set the foreground

textBlock.Foreground = new System.Windows.Media.SolidColorBrush(color); 

There appears to be something going wrong with the release build either failing to include the appropriate codecs or else misidentifying the codec to use for system APIs. Since the python_d executable is working, what does that return for os.getfsencoding()? (Use the C API to call that between your Initialize/Finalize calls)

Your format specifier is incorrect. From the printf() man page on my machine:

0 A zero '0' character indicating that zero-padding should be used rather than blank-padding. A '-' overrides a '0' if both are used;

Field Width: An optional digit string specifying a field width; if the output string has fewer characters than the field width it will be blank-padded on the left (or right, if the left-adjustment indicator has been given) to make up the field width (note that a leading zero is a flag, but an embedded zero is part of a field width);

Precision: An optional period, '.', followed by an optional digit string giving a precision which specifies the number of digits to appear after the decimal point, for e and f formats, or the maximum number of characters to be printed from a string; if the digit string is missing, the precision is treated as zero;

For your case, your format would be %09.3f:

#include <stdio.h>

int main(int argc, char **argv)
{
  printf("%09.3f\n", 4917.24);
  return 0;
}

Output:

$ make testapp
cc     testapp.c   -o testapp
$ ./testapp 
04917.240

Note that this answer is conditional on your embedded system having a printf() implementation that is standard-compliant for these details - many embedded environments do not have such an implementation.

>>> import pandas as pd
>>> df = pd.DataFrame({'Position':[1,2,3,4,5], 'Letter':['a', 'b', 'c', 'd', 'e']})
>>> dict(sorted(df.values.tolist())) # Sort of sorted... 
{'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5}
>>> from collections import OrderedDict
>>> OrderedDict(df.values.tolist())
OrderedDict([('a', 1), ('b', 2), ('c', 3), ('d', 4), ('e', 5)])

In Long

Explaining solution: dict(sorted(df.values.tolist()))

Given:

df = pd.DataFrame({'Position':[1,2,3,4,5], 'Letter':['a', 'b', 'c', 'd', 'e']})

[out]:

 Letter Position
0   a   1
1   b   2
2   c   3
3   d   4
4   e   5

Try:

# Get the values out to a 2-D numpy array, 
df.values

[out]:

array([['a', 1],
       ['b', 2],
       ['c', 3],
       ['d', 4],
       ['e', 5]], dtype=object)

Then optionally:

# Dump it into a list so that you can sort it using `sorted()`
sorted(df.values.tolist()) # Sort by key

Or:

# Sort by value:
from operator import itemgetter
sorted(df.values.tolist(), key=itemgetter(1))

[out]:

[['a', 1], ['b', 2], ['c', 3], ['d', 4], ['e', 5]]

Lastly, cast the list of list of 2 elements into a dict.

dict(sorted(df.values.tolist())) 

[out]:

{'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5}

Answering @sbradbio comment:

If there are multiple values for a specific key and you would like to keep all of them, it's the not the most efficient but the most intuitive way is:

from collections import defaultdict
import pandas as pd

multivalue_dict = defaultdict(list)

df = pd.DataFrame({'Position':[1,2,4,4,4], 'Letter':['a', 'b', 'd', 'e', 'f']})

for idx,row in df.iterrows():
    multivalue_dict[row['Position']].append(row['Letter'])

[out]:

>>> print(multivalue_dict)
defaultdict(list, {1: ['a'], 2: ['b'], 4: ['d', 'e', 'f']})

If you by writing "non letters and numbers" exclude more than [A-Za-z0-9] (ie. considering letters like åäö to be letters to) and want to be able to accurately handle UTF-8 strings \p{L} and \p{N} will be of aid.

1. \p{N} will match any "Number"
2. \p{L} will match any "Letter Character", which includes
   • Lower case letter
   • Modifier letter
   • Other letter
   • Title case letter
   • Upper case letter

Documentation PHP: Unicode Character Properties

$data = "Thäre!wouldn't%bé#äny";

$new_data = str_replace  ("'", "", $data);
$new_data = preg_replace ('/[^\p{L}\p{N}]/u', '_', $new_data);

var_dump (
  $new_data
);

output

string(23) "Thäre_wouldnt_bé_äny"

Chrome Version 50.0.2661.87 m does not support the mm-dd-yy format when assigned to a variable. It uses yy-mm-dd. IE and Firefox work as expected.

TL;DR:

{ withCredentials: true } or axios.defaults.withCredentials = true

From the axios documentation

withCredentials: false, // default

withCredentials indicates whether or not cross-site Access-Control requests should be made using credentials

If you pass { withCredentials: true } with your request it should work.

A better way would be setting withCredentials as true in axios.defaults

axios.defaults.withCredentials = true

Use the following instead:

boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );

This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.

Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

Try this

 echo "hello world" | sed 's/ /./g' 

This is now part of the language. See TypeScriptLang.org > Basic Types > enum for the documentation on this. An excerpt from the documentation on how to use these enums:

enum Color {Red, Green, Blue};
var c: Color = Color.Green;

Or with manual backing numbers:

enum Color {Red = 1, Green = 2, Blue = 4};
var c: Color = Color.Green;

You can also go back to the enum name by using for example Color[2].

Here's an example of how this all goes together:

module myModule {
    export enum Color {Red, Green, Blue};

    export class MyClass {
        myColor: Color;

        constructor() {
            console.log(this.myColor);
            this.myColor = Color.Blue;
            console.log(this.myColor);
            console.log(Color[this.myColor]);
        }
    }
}

var foo = new myModule.MyClass();

This will log:

undefined  
2  
Blue

Because, at the time of writing this, the Typescript Playground will generate this code:

var myModule;
(function (myModule) {
    (function (Color) {
        Color[Color["Red"] = 0] = "Red";
        Color[Color["Green"] = 1] = "Green";
        Color[Color["Blue"] = 2] = "Blue";
    })(myModule.Color || (myModule.Color = {}));
    var Color = myModule.Color;
    ;
    var MyClass = (function () {
        function MyClass() {
            console.log(this.myColor);
            this.myColor = Color.Blue;
            console.log(this.myColor);
            console.log(Color[this.myColor]);
        }
        return MyClass;
    })();
    myModule.MyClass = MyClass;
})(myModule || (myModule = {}));
var foo = new myModule.MyClass();

When you say "full-screen", do you mean like full-screen for the computer, or for taking up the entire space in the browser?

You can't force the user into full-screen F11; however, you can make your div full screen by using the following CSS

div {width: 100%; height: 100%;}

This will of course assume your div is child of the <body> tag. Otherwise, you'd need to add the following in addition to the above code.

div {position: absolute; top: 0; left: 0;}

If you need to get the generic type of a returned type, I used this approach when I needed to find methods in a class which returned a Collection and then access their generic types:

import java.lang.reflect.Method;
import java.lang.reflect.ParameterizedType;
import java.lang.reflect.Type;
import java.util.Collection;
import java.util.List;

public class Test {

    public List<String> test() {
        return null;
    }

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

        for (Method method : Test.class.getMethods()) {
            Class returnClass = method.getReturnType();
            if (Collection.class.isAssignableFrom(returnClass)) {
                Type returnType = method.getGenericReturnType();
                if (returnType instanceof ParameterizedType) {
                    ParameterizedType paramType = (ParameterizedType) returnType;
                    Type[] argTypes = paramType.getActualTypeArguments();
                    if (argTypes.length > 0) {
                        System.out.println("Generic type is " + argTypes[0]);
                    }
                }
            }
        }

    }

}

This outputs:

Generic type is class java.lang.String

Today (2.5 years after this answer) you can safely use Array.forEach. As @ricosrealm suggests, decodeURIComponent was used in this function.

function getJsonFromUrl(url) {
  if(!url) url = location.search;
  var query = url.substr(1);
  var result = {};
  query.split("&").forEach(function(part) {
    var item = part.split("=");
    result[item[0]] = decodeURIComponent(item[1]);
  });
  return result;
}

actually it's not that simple, see the peer-review in the comments, especially:

• hash based routing (@cmfolio)
• array parameters (@user2368055)
• proper use of decodeURIComponent and non-encoded = (@AndrewF)
• non-encoded + (added by me)

For further details, see MDN article and RFC 3986.

Maybe this should go to codereview SE, but here is safer and regexp-free code:

function getJsonFromUrl(url) {
  if(!url) url = location.href;
  var question = url.indexOf("?");
  var hash = url.indexOf("#");
  if(hash==-1 && question==-1) return {};
  if(hash==-1) hash = url.length;
  var query = question==-1 || hash==question+1 ? url.substring(hash) : 
  url.substring(question+1,hash);
  var result = {};
  query.split("&").forEach(function(part) {
    if(!part) return;
    part = part.split("+").join(" "); // replace every + with space, regexp-free version
    var eq = part.indexOf("=");
    var key = eq>-1 ? part.substr(0,eq) : part;
    var val = eq>-1 ? decodeURIComponent(part.substr(eq+1)) : "";
    var from = key.indexOf("[");
    if(from==-1) result[decodeURIComponent(key)] = val;
    else {
      var to = key.indexOf("]",from);
      var index = decodeURIComponent(key.substring(from+1,to));
      key = decodeURIComponent(key.substring(0,from));
      if(!result[key]) result[key] = [];
      if(!index) result[key].push(val);
      else result[key][index] = val;
    }
  });
  return result;
}

This function can parse even URLs like

var url = "?foo%20e[]=a%20a&foo+e[%5Bx%5D]=b&foo e[]=c";
// {"foo e": ["a a",  "c",  "[x]":"b"]}

var obj = getJsonFromUrl(url)["foo e"];
for(var key in obj) { // Array.forEach would skip string keys here
  console.log(key,":",obj[key]);
}
/*
  0 : a a
  1 : c
  [x] : b
*/

It is general practice in various messaging protocols to keep heartbeating each other (keep sending ping packets) the packet does not need to be very large. The probing mechanism will allow you to detect the disconnected client even before TCP figures it out in general (TCP timeout is far higher) Send a probe and wait for say 5 seconds for a reply, if you do not see reply for say 2-3 subsequent probes, your player is disconnected.

Also, related question

"_blank" is not guaranteed to be a new tab or window. It's implemented differently per-browser.

You can, however, put anything into target. I usually just say "_tab", and every browser I know of just opens it in a new tab.

Be aware that it means it's a named target, so if you try to open 2 URLs, they will use the same tab.

You can just do a get on the collection then just modify the attributes of the customer you just did a 'get' on. There is no need to modify the collection nor is there a need to create a new customer:

int currentCustomer = 3;

// get the customer at 3
Customer c = list.get(currentCustomer);
// change his email
c.setEmail("[email protected]");

Just my 2 cents, had:

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

at the end of body, wasn't working, had to add crossorigin="anonymous" and now it's working, Bootstrap version 3.3.6. ...

if column = None

COLUMN_OLD_VALUE
----------------
None
1
None
100
20
------------------

Use create a temptable on data frame:

sqlContext.sql("select * from tempTable where column_old_value='None' ").show()

So use : column_old_value='None'

You can't from C#. From IL, this is actually supported. You can do a non-virt call to any of your parent classes... but please don't. :)

It's very simple.

1. You add an image.

2. You create a css property to this image.

   img { transition: all 0.3s ease-in-out 0s; }
   

3. You add an animation like that:

   img:hover
   {
       cursor: default;
       transform: rotate(360deg);
       transition: all 0.3s ease-in-out 0s;
   }
   

Try this:

Select user_id
from yourtable
where ancestry in ('England', 'France', 'Germany')
group by user_id
having count(user_id) = 3

The last line means the user's ancestry has all 3 countries.

df.groupby('l_customer_id_i').agg(lambda x: ','.join(x)) does already return a dataframe, so you cannot loop over the groups anymore.

In general:

• df.groupby(...) returns a GroupBy object (a DataFrameGroupBy or SeriesGroupBy), and with this, you can iterate through the groups (as explained in the docs here). You can do something like:

  grouped = df.groupby('A')
  
  for name, group in grouped:
      ...
  

• When you apply a function on the groupby, in your example df.groupby(...).agg(...) (but this can also be transform, apply, mean, ...), you combine the result of applying the function to the different groups together in one dataframe (the apply and combine step of the 'split-apply-combine' paradigm of groupby). So the result of this will always be again a DataFrame (or a Series depending on the applied function).

If you want to use location.href to avoid popup problems, you can use an empty <a> ref and then use javascript to click it.

something like in HTML

<a id="anchorID" href="mynewurl" target="_blank"></a>

Then javascript click it as follows

document.getElementById("anchorID").click();

import os, platform
os.chdir('c:\\Users\\MS\\Desktop')

try :
    file = open("Learn Python.txt","a")
    print('this file is exist')
except:
    print('this file is not exist')
file.write('\n''Hello Ashok')

fhead = open('Learn Python.txt')

for line in fhead:

    words = line.split()
print(words)

My 2 cents:

I did notice that some singleton / static fields were reseted when my activity was destroyed. I noticed this on some low end 2.3 devices.

My case was very simple : I just have a private filed "init_done" and a static method "init" that I called from activity.onCreate(). I notice that the method init was re-executing itself on some re-creation of the activity.

While I cannot prove my affirmation, It may be related to WHEN the singleton/class was created/used first. When the activity get destroyed/recycled, it seem that all class that only this activity refer are recycled too.

I moved my instance of singleton to a sub class of Application. I acces them from the application instance. and, since then, did not notice the problem again.

I hope this can help someone.

Bit of a tweak to Jocker's response (I would post as a comment, but I don't have enough karma yet):

SELECT TABLE_NAME, ENGINE
  FROM information_schema.TABLES
 WHERE TABLE_SCHEMA = 'database' AND ENGINE IS NOT NULL;

This excludes MySQL views from the list, which don't have an engine.

.ix indexer works okay for pandas version prior to 0.20.0, but since pandas 0.20.0, the .ix indexer is deprecated, so you should avoid using it. Instead, you can use .loc or iloc indexers. You can solve this problem by:

mask = df.my_channel > 20000
column_name = 'my_channel'
df.loc[mask, column_name] = 0

Or, in one line,

df.loc[df.my_channel > 20000, 'my_channel'] = 0

mask helps you to select the rows in which df.my_channel > 20000 is True, while df.loc[mask, column_name] = 0 sets the value 0 to the selected rows where maskholds in the column which name is column_name.

Update: In this case, you should use loc because if you use iloc, you will get a NotImplementedError telling you that iLocation based boolean indexing on an integer type is not available.

You actually had it correct in your third attempt.

 <select ng-model="myselect" ng-options="o as o for o in options"></select>

See a working example here: http://plnkr.co/edit/xEERH2zDQ5mPXt9qCl6k?p=preview

The trick is that AngularJS writes the keys as numbers from 0 to n anyway, and translates back when updating the model.

As a result, the HTML will look incorrect but the model will still be set properly when choosing a value. (i.e. AngularJS will translate '0' back to 'var1')

The solution by Epokk also works, however if you're loading data asynchronously you might find it doesn't always update correctly. Using ngOptions will correctly refresh when the scope changes.

See Google's solution to this problem. You basically have to scroll content yourself using JavaScript. Sencha Touch also provides a library for getting this behavior in a very performant manor.

Passing data from one Activity to Activity in android

An intent contains the action and optionally additional data. The data can be passed to other activity using intent putExtra() method. Data is passed as extras and are key/value pairs. The key is always a String. As value you can use the primitive data types int, float, chars, etc. We can also pass Parceable and Serializable objects from one activity to other.

Intent intent = new Intent(context, YourActivity.class);
intent.putExtra(KEY, <your value here>);
startActivity(intent);

Retrieving bundle data from android activity

You can retrieve the information using getData() methods on the Intent object. The Intent object can be retrieved via the getIntent() method.

 Intent intent = getIntent();
  if (null != intent) { //Null Checking
    String StrData= intent.getStringExtra(KEY);
    int NoOfData = intent.getIntExtra(KEY, defaultValue);
    boolean booleanData = intent.getBooleanExtra(KEY, defaultValue);
    char charData = intent.getCharExtra(KEY, defaultValue); 
  }

The short answer is adding a class directly to the element you want to style is indeed the most efficient way to target and style that Element. BUT, in real world scenarios it is so negligible that it is not an issue at all to worry about.

To quote Steve Ouders (CSS optimization expert) http://www.stevesouders.com/blog/2009/03/10/performance-impact-of-css-selectors/:

Based on tests I have the following hypothesis: For most web sites, the possible performance gains from optimizing CSS selectors will be small, and are not worth the costs.

Maintainability of code is much more important in real world scenarios. Since the underlying topic here is front-end performance; the real performance boosters for speedy page rendering are found in:

• Make fewer HTTP requests
• Use a CDN
• Add an Expires header
• Gzip components
• Put stylesheets at the top
• Put scripts at the bottom
• Avoid CSS expressions
• Make JS and CSS external
• Reduce DNS lookups
• Minify JS
• Avoid redirects
• Remove duplicate scripts
• Configure ETags
• Make AJAX cacheable

Source: http://stevesouders.com/docs/web20expo-20090402.ppt

So just to confirm, the answer is yes, example below is indeed faster but be aware of the bigger picture:

<div class="column">
   <img class="custom-style" alt="appropriate alt text" />
</div>

What about just adding android:windowSoftInputMode="stateHidden" on your activity in the manifest.

2018 here, this is what I do:

$(inputs).on('change keydown paste input propertychange click keyup blur',handler);

If you can point out flaws in this approach, I would be grateful.

You can create a one-way hash with bcrypt using PHP's crypt() function and passing in an appropriate Blowfish salt. The most important of the whole equation is that A) the algorithm hasn't been compromised and B) you properly salt each password. Don't use an application-wide salt; that opens up your entire application to attack from a single set of Rainbow tables.

PHP - Crypt Function

To add on to this:

If you're using CMAKE to generate a Visual Studio solution, and you want Visual Studio to output compiled files into /bin, Peter's answer needs to be modified a bit:

# set output directories for all builds (Debug, Release, etc.)
foreach( OUTPUTCONFIG ${CMAKE_CONFIGURATION_TYPES} )
    string( TOUPPER ${OUTPUTCONFIG} OUTPUTCONFIG )
    set( CMAKE_ARCHIVE_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${CMAKE_SOURCE_DIR}/lib )
    set( CMAKE_LIBRARY_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${CMAKE_SOURCE_DIR}/lib )
    set( CMAKE_RUNTIME_OUTPUT_DIRECTORY_${OUTPUTCONFIG} ${CMAKE_SOURCE_DIR}/bin )
endforeach( OUTPUTCONFIG CMAKE_CONFIGURATION_TYPES )

if (Enum.IsDefined(typeof(foo), value))
{
   return (Foo)Enum.Parse(typeof(foo), value);
}

Hope this helps

Edit This answer got down voted as value in my example is a string, where as the question asked for an int. My applogies; the following should be a bit clearer :-)

Type fooType = typeof(foo);

if (Enum.IsDefined(fooType , value.ToString()))
{
   return (Foo)Enum.Parse(fooType , value.ToString());
}
