I had the exact same problem while trying to setup a Gitlab pipeline executed by a Docker runner installed on a Raspberry Pi 4

Using nload to follow bandwidth usage within Docker runner container while pipeline was cloning the repo i saw the network usage dropped down to a few bytes per seconds..

After a some deeper investigations i figured out that the Raspberry temperature was too high and the network card start to dysfunction above 50° Celsius.

Adding a fan to my Raspberry solved the issue.

First, check if your php.ini has the extension enabled "php_pdo_mysql" and "php_mysqli" and the path of "extension_dir" is correct. If you need one of above configuration, then, you must restart the php-fpm to apply the changes.

In my case (where i am using the Windows OS in the company, i really prefer OSX or Linux), i solved the problem putting this values in the php.ini:

; ...

extension_dir = "ext"

; ... 

extension=php_mysqli.dll
extension=php_pdo_mysql.dll

; ...

I hope this helps.

in bluehost i could not reset password; with this driver worked:

MAIL_DRIVER=sendmail

This worked for me

1- Go to ~/.android/ and remove “adbkey”
2- Disconnect USB connection
3- adb kill-server
4- Revoke USB debugging authorizations (in developer option)
5- Reconnect the device to the Ma
6- adb devices

That error message usually means that either the password we are using doesn't match what MySQL thinks the password should be for the user we're connecting as, or a matching MySQL user doesn't exist (hasn't been created).

In MySQL, a user is identified by both a username ("test2") and a host ("localhost").

The error message identifies the user ("test2") and the host ("localhost") values...

  'test2'@'localhost'

We can check to see if the user exists, using this query from a client we can connect from:

 SELECT user, host FROM mysql.user

We're looking for a row that has "test2" for user, and "localhost" for host.

 user     host       
 -------  -----------
 test2     127.0.0.1  cleanup
 test2     ::1        
 test2     localhost  

If that row doesn't exist, then the host may be set to wildcard value of %, to match any other host that isn't a match.

If the row exists, then the password may not match. We can change the password (if we're connected as a user with sufficient privileges, e.g. root

 SET PASSWORD FOR 'test2'@'localhost' = PASSWORD('mysecretcleartextpassword')

We can also verify that the user has privileges on objects in the database.

 GRANT SELECT ON jobs.* TO 'test2'@'localhost' 

EDIT

If we make changes to mysql privilege tables with DML operations (INSERT,UPDATE,DELETE), those changes will not take effect until MySQL re-reads the tables. We can make changes effective by forcing a re-read with a FLUSH PRIVILEGES statement, executed by a privileged user.

As you are learning, performance problems with AS are not trivial to diagnose! In my case, an array of 9215-character-long strings (see below) was causing AS to dump threads every time I typed a few characters. The thread dump in turn caused AS to freeze for many seconds at a time. This bug appeared in the Windows 64 bit release of AS 2.2, still occurs in 2.2.1, but was not present in 2.1.

Finding out that long strings were causing my lockups involved a lot of trial and error. But, I learned a lot in the process, to wit:

• idea.log contains excellent diagnostics (Help->Show Log in Explorer);
• If you see extreme, but intermittent slowdowns, suspect AS is dumping threads. This will be reported in idea.log. If threads are being dumped, the dumps will tell what code AS was executing when the problem occurred;
• Find out whether the problem occurs in other projects. If not:
  • Look for unusual content in the project file you are editing when it happens (atypical indentation, long lines, overall size, special characters, etc.);
  • Try exporting settings from another project (File->Export Settings) and importing them to the problem project (File->Import Settings);
• If so:
  • If threads were dumped, consult these and text in idea.log near in time to the dump notices for details;
  • Consult idea.log for messages about memory consumption and see other answers to this question such as https://stackoverflow.com/a/30818099/5025060 for advice regarding memory and other tunables.

BTW, for the present I have worked around the problem I describe above by moving my long strings into a separate file (a new class containing only the array itself). I try not to edit this file with AS:

package com.code_read.numerous;

// Stored in this separate file as workaround for but in Android Studio 2.2 and 2.2.1:
public class numstrings {

    // Array of long random numbers, pregenerated to save CPU:
    public static String[] numStrings = {

For mac osx users

    brew tap homebrew/cask
    brew cask install chromedriver

After six days I find the answer which make me crazy! The answer is disable proxy at web.config file:

<system.net>
  <defaultProxy> 
    <proxy usesystemdefault="False"/> 
  </defaultProxy>
</system.net>

For PHP 7 in Ubuntu you can also do:

sudo apt-get install php7.0-pgsql

So, now you can do not uncomment lines in php.ini

UPD: I have a same error, so problem was not in driver. I changed my database.ini, but every time I saw an error. And I change database config in .env and errors gone.

Edit your conf/log4j.properties file and Change the following line:

   log4j.rootCategory=INFO, console

to

    log4j.rootCategory=ERROR, console

Another approach would be to :

Fireup spark-shell and type in the following:

import org.apache.log4j.Logger
import org.apache.log4j.Level

Logger.getLogger("org").setLevel(Level.OFF)
Logger.getLogger("akka").setLevel(Level.OFF)

You won't see any logs after that.

For me, running the ad-hoc network on Windows 8.1, it was two things:

• I had to set a static IP on my Android (under Advanced Options under where you type the Wifi password)
• I had to use a password 8 characters long

Any IP will allow you to connect, but if you want internet access the static IP should match the subnet from the shared internet connection.

I'm not sure why I couldn't get a longer password to work, but it's worth a try. Maybe a more knowledgeable person could fill us in.

In configuration where windows is a host, and linux is a guest I found solution of the same problem in other place.

So again, the error message was "Failed to mount folders in Linux guest. This is usually because the "vboxsf" file system is not available." (...)

This was caused because I have made mistake by doing symlink inside the guest system from /vagrant into /home/vagrant/vagrant. The point is, that the directory /vagrant is a normal linux directory that has a symlink (so all ok), but when booting up by "vagrant up", it tries to mount windows directory on that place, and windows directory cannot work as a symlink. Windows host does not support linux symlinks.

So what You can do then, is to ssh into guest, remove the symlink wherever You have it, and reload machine.

In my configuration it was: Vagrant 1.7.2, VBoxGuestAdditions 4.3.28 and VBox 4.3.28.

You can download IE Driver (both 32 and 64-bit) from Selenium official site: http://docs.seleniumhq.org/download/

32 bit Windows IE

64 bit Windows IE

IE Driver is also available in the following site:

http://selenium-release.storage.googleapis.com/index.html

For those people to whom none of the answers worked.... try closing the chrome://inspect/#devices tab in chrome if opened... This worked for me.

Control Panel >> Windows Firewall

Advanced settings >> Inbound Rules >> World Wide Web Services - Enable it All or (Domain, Private, Public) as needed.

Try to change where Member class

public function users() {
    return $this->hasOne('User');
} 

return $this->belongsTo('User');

In my case:

• The phone was connected as a media device.
• Clicked on that message and got a menu. "USB computer connection"
• In that menu chose to connect it as a camera (for devices that do not support MTP)

And then it worked.

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.ie.*;

public class IEclass {



public static void main(String[] args) {

System.setProperty("webdriver.ie.driver","S:\\IE and Chrome ServerDriver\\IEDriverServer.exe");

WebDriver driver = new InternetExplorerDriver();

driver.get("https://www.google.com");
  }
    }

If you are using Oracle 10g, you can use the DECODE function to pivot the rows into columns:

CREATE TABLE doc_tab (
  loan_number VARCHAR2(20),
  document_type VARCHAR2(20),
  document_id VARCHAR2(20)
);

INSERT INTO doc_tab VALUES('992452533663', 'Voters ID', 'XPD0355636');
INSERT INTO doc_tab VALUES('992452533663', 'Pan card', 'CHXPS5522D');
INSERT INTO doc_tab VALUES('992452533663', 'Drivers licence', 'DL-0420110141769');

COMMIT;

SELECT
    loan_number,
    MAX(DECODE(document_type, 'Voters ID', document_id)) AS voters_id,
    MAX(DECODE(document_type, 'Pan card', document_id)) AS pan_card,
    MAX(DECODE(document_type, 'Drivers licence', document_id)) AS drivers_licence
  FROM
    doc_tab
GROUP BY loan_number
ORDER BY loan_number;

Output:

LOAN_NUMBER   VOTERS_ID            PAN_CARD             DRIVERS_LICENCE    
------------- -------------------- -------------------- --------------------
992452533663  XPD0355636           CHXPS5522D           DL-0420110141769     

You can achieve the same using Oracle PIVOT clause, introduced in 11g:

SELECT *
  FROM doc_tab
PIVOT (
  MAX(document_id) FOR document_type IN ('Voters ID','Pan card','Drivers licence')
);

I just wanted to bring a small contribution, because I have been able to debug on my Nexus 5 device on Windows 8, without doing all of this.

When I plugged it, there wasn't any yellow exclamation mark within Device Manager. So for me, the drivers were OK. But the device was not listed within my Eclipse DDMS. After a little bit of searching, it was just an option to change in the device settings. By default, the Nexus 5 USB computer connection is in MTP mode (Media Device).

What you have to do is:

• Unplug the device from the computer
• Go to Settings -> Storage.
• In the ActionBar, click the option menu and choose "USB computer connection".
• Check "Camera (PTP)" connection.
• Plug the device and you should have a popup on the device allowing you to accept the computer's incoming connection, or something like that.
• Finally, you should see it now in the DDMS and voilà.

I hope this will help!

Another possible reason for this error for the Mega 2560 is if your code has three exclamation marks in a row. Perhaps in a recently added string.

3 bang marks in a row causes the Mega 2560 bootloader to go into Monitor mode from which it can not finish programming.

"!!!" <--- breaks Mega 2560 bootloader.

To fix, unplug the Arduino USB to reset the COM port and then recompile with only two exclamation points or with spaces between or whatever. Then reconnect the Arduino and program as usual.

Yes, this bit me yesterday and today I tracked down the culprit. Here is a link with more information: http://forum.arduino.cc/index.php?topic=132595.0

SkipSoft.net has some great toolkits. I ran into a similar problem with my Galaxy Nexus.... Ran the corresponding toolkit, which configured my system and downloaded the correct drivers. I then went into Windows Hardware manager after connecting the phone... Windows reported the exclamation that it couldn't find the device driver, so I ran update, and gave it the drivers directory the toolkit had created... and everything started working great. Hope this helps :)

netsh wlan set hostednetwork mode=allow ssid=dhiraj key=7870049877

1.) Delete ~/.android/adbkey on your desktop machine

2.) Run command "adb kill-server"

3.) Run command "adb start-server"

You should now be prompted to accept debug key.

I faced the same problem, tried the first answer but something was missing.

If you guys are using Webpack, your css will be loaded as a style tag which is not supported by respond.js, it needs a file, so make sure bootstrap is loaded as a css file

Personally I used extract-text-webpack-plugin

const webpack = require("webpack")
const ExtractTextPlugin = require("extract-text-webpack-plugin")
const path = require("path")

module.exports = {
    context: __dirname+"/src",
    entry: "./index.js",
    output: {
        filename: "./dist/bundle.js",
        path: __dirname
    },
    plugins: [
        ...,
        new ExtractTextPlugin("./dist/bootstrap.css", {
            allChunks: true
        })
    ],
    module: {
        loaders: [
            ...,
            // your css loader excluding bootstrap
            {
                test: /\.css$/,
                loader: "style!css",
                exclude: [
                    path.resolve(__dirname, "node_modules/bootstrap/dist/css/bootstrap.css")
                ]
            },

            {
                // loads bootstrap as a file, change path accordingly if needs be, path needs to be absolute
                include: [
                    path.resolve(__dirname, "node_modules/bootstrap/dist/css/bootstrap.css")
                ],
                loader: ExtractTextPlugin.extract("style-loader", "css-loader?minimize")
            }
        ]
    }
}

Hope it will help you

Just download and install "Samsung Kies" from this link. and everything would work as required.

Before installing, uninstall the drivers you have installed for your device.

Update:

Two possible solutions:

1. Try with the Google USB driver which comes with the SDK.
2. Download and install the Samsung USB driver from this link as suggested by Mauricio Gracia Gutierrez

this is an old post but...

just surprised that nobody talk about pg_hba file as it can be a good reason to get this error code.

Check here for those who forgot to configure it: http://www.postgresql.org/docs/current/static/auth-pg-hba-conf.html

For me it worked after manually copying the sqljdbc4-2.jar into WEB-INF/lib folder. So please have a try on this too.

Some of you may have experienced this issue. If you don't find the USB driver (like me, I downloaded a bundle of Eclipse and the Android SDK), go to <sdk>/SDK Manager. Open it and select USB Driver from the options to install and you are ready. I had to do the PTP mode too.

To take care of the Drive-related imports, you'll need a few jars from the Google Drive SDK. There are a few large ones, so you may want to add them individually to suit your app.

If that doesn't resolve the com.google.android.gms.* imports, the Google Play Services add-on needs to be installed (from Extras -> Google Play Services in the SDK Manager) and google-play-services.jar needs to be added to your build path.

EDIT:

In this case, the following jars were needed:

google-api-services-drive-v2-rev1-1.7.2-beta.jar

google-http-client-1.10.3-beta.jar

google-http-client-android2-1.10.3-beta.jar

google-oauth-client-1.10.1-beta.jar

I had the exact problem and I couldn't find the hosted network adapter in network connections or device manager. So what I did was to disable and enable the wifi adapter after this the hosted network adapter should be listed in the device manager, then you just enable the adapter from there.

you can just find-out loaded config file by executing below command,

 php -i | grep 'php.ini'

Then add below lines to correct php.ini file

extension=pdo.so
extension=pdo_sqlite.so
extension=pdo_mysql.so
extension=sqlite.so

Then restart web server,

service httpd restart

The error message says

"The path to the driver executable must be set by the webdriver.ie.driver system property;"

You are setting the path for the Chrome Driver with "webdriver.chrome.driver" property. You are not setting the file location when for InternetExplorerDriver, to do that you must set "webdriver.ie.driver" property.

You can set these properties in your shell, via maven, or your IDE with the -DpropertyName=Value

-Dwebdriver.ie.driver="C:/.../IEDriverServer.exe" 

You need to use quotes because of spaces or slashes in your path on windows machines, or alternatively reverse the slashes other wise they are the string string escape prefix.

You could also use

System.setProperty("webdriver.ie.driver","C:/.../IEDriverServer.exe"); 

inside your code.

For new browsers: Object.keys( MY_DICTIONARY ) will return an array of keys. Else you may want to go the old school way:

var keys = []
for(var key in dic) keys.push( key );

The difference is in view-port wire-frame rendering and double-sided polygon rendering, which is very common in professional CAD/3D software but not in games.

The difference is almost 10x-13x faster in single-fixed rendering pipeline (now very obsolete but some CAD software using it) rendering double sided polygons and wireframes:

Thats how entry level Quadro beats high-end GeForce. At least in the single-fixed pipeline using legacy calls like glLightModel(GL_LIGHT_MODEL_TWO_SIDE, GL_TRUE). The trick is done with driver optimization (does not matter if its single-fixed pipeline Direct3D or OpenGL). And its true that on some GeForce cards some firmware/hardware hacking can unlock the features.

If double sided is implemented using shader code, the GeForce has to render the polygon twice giving the Quadro only 2x the speed difference (it's less in real-world). The wireframe rendering remains much much slower on GeForce even if implemented in a modern way.

Todays GeForce cards can render millions of polygons per second, drawing lines with faded polygons can result in 100x speed difference eliminating the Quadro benefit.

Quadro equivalent GTX cards have usually better clock speeds giving 2%-10% better performance in games.

So to sum up:

The Quadro rules the single-fixed legacy now obsolete rendering pipeline (which CAD uses), but by implementing modern rendering methods this can be significantly reduced (virtually no speed gain in Maya's Viewport 2.0, it uses GLSL effects - very similar to game engine).

Other reasons to get Quadro are double precision float computations for science, better warranty and display's support for professionals.

That's about it, price-vise the Quadros or FirePros are artificially overpriced.

This issue came for me due to the fact that .. i was running server with selenium-server-standalone-2.32.0 and client registered with selenium-server-standalone-2.37.0 .. When i made both selenium-server-standalone-2.32.0 and ran then things worked fine

The hosts file is for host name resolution only (on Windows as well as on Unix-like systems). You cannot put port numbers in there, and there is no way to do what you want with generic OS-level configuration - the browser is what selects the port to choose.

So use bookmarks or something like that.
(Some firewall/routing software might allow outbound port redirection, but that doesn't really sound like an appealing option for this.)

I dont think youre returning json object from server. just a string.

you need the dataType of the return object to be json

you can download and install db2client and looking for - db2jcc.jar - db2jcc_license_cisuz.jar - db2jcc_license_cu.jar - and etc. at C:\Program Files (x86)\IBM\SQLLIB\java

Quoting http://php.net/manual/en/intro.mssql.php:

The MSSQL extension is not available anymore on Windows with PHP 5.3 or later. SQLSRV, an alternative driver for MS SQL is available from Microsoft: » http://msdn.microsoft.com/en-us/sqlserver/ff657782.aspx.

Once you downloaded that, follow the instructions at this page:

• Loading the Microsoft Drivers for PHP for SQL Server

In a nutshell:

Put the driver file in your PHP extension directory.
Modify the php.ini file to include the driver. For example:

extension=php_sqlsrv_53_nts_vc9.dll  

Restart the Web server.

See Also (copied from that page)

• System Requirements (Microsoft Drivers for PHP for SQL Server)
• Getting Started
• Programming Guide
• SQLSRV Driver API Reference (Microsoft Drivers for PHP for SQL Server)

The PHP Manual for the SQLSRV extension is located at http://php.net/manual/en/sqlsrv.installation.php and offers the following for Installation:

The SQLSRV extension is enabled by adding appropriate DLL file to your PHP extension directory and the corresponding entry to the php.ini file. The SQLSRV download comes with several driver files. Which driver file you use will depend on 3 factors: the PHP version you are using, whether you are using thread-safe or non-thread-safe PHP, and whether your PHP installation was compiled with the VC6 or VC9 compiler. For example, if you are running PHP 5.3, you are using non-thread-safe PHP, and your PHP installation was compiled with the VC9 compiler, you should use the php_sqlsrv_53_nts_vc9.dll file. (You should use a non-thread-safe version compiled with the VC9 compiler if you are using IIS as your web server). If you are running PHP 5.2, you are using thread-safe PHP, and your PHP installation was compiled with the VC6 compiler, you should use the php_sqlsrv_52_ts_vc6.dll file.

The drivers can also be used with PDO.

I was using Genymotion 2.9.0. I updated to 3.0.0 Now it is working. So please check Genymotion version.

The most succinct way to do this is:

Get-WmiObject -Class win32_computersystem -Property *

Try doing this:

• Unplug the device
• Execute adb kill-server && adb start-server(that restarts adb)
• Re-plug the device

Also you can try to edit an adb config file .android/adb_usb.ini and add a line 04e8 after the header. Restart adb required for changes to take effect.

The method I ended up using is very simple:

$query = 'SELECT a, b, c FROM tbl WHERE oele = 2 GROUP BY boele';
$nrows = $db->query("SELECT COUNT(1) FROM ($query) x")->fetchColumn();

Might not be the most efficient, but it seems to be foolproof, because it actually counts the original query's results.

You will need USB driver installed correctly and have debugging enabled in settings. if these dont work there could be something wrong with your device.

Also see this.

Just happened to me when trying to send_keys to a search input box - that has autoupdate depending on what you type in. As mentioned by Eero, this can happen if your element does some Ajax updated while you are typing in your text inside the input element. The solution is to send one character at a time and search again for the input element. (Ex. in ruby shown below)

def send_keys_eachchar(webdriver, elem_locator, text_to_send)
  text_to_send.each_char do |char|
    input_elem = webdriver.find_element(elem_locator)
    input_elem.send_keys(char)
  end
end

Long time reader, first time helper ;)

I'm going through the same hellish experience here with a Prolific USB <> Serial adapter and so far Linux is the easiest to get it to work.

On CentOS, I didn't need to install any drivers etc.. That said,

• dmesg | grep -i tty or dmesg | grep -i usb showed me /dev/ttyUSB0.
• screen ttyUSB0 9600 didn't do the trick for me like it did in OSX
• minicom is new to me but it was complaining about lack of /dev/modem

However, this helped: https://www.centos.org/forums/viewtopic.php?t=21271

So install minicom (yum install minicom) then enter its settings (minicom -s).

Then select Serial Port Setup and change the Serial Device (Option A) to /dev/ttyUSB0, or whatever your device file is as it slightly differs per distro.

Then change the Bps (Option E) to 9600 and the rest should be default (8N1 Y N)

Save as default, then simply minicom and Bob's your uncle.

HTH.

I know this is for php, but I got here looking for a solution for node. Using mongoskin:

mongodb.admin().ping(function(err) {
    if(err === null)
        // true - you got a conntion, congratulations
    else if(err.message.indexOf('failed to connect') !== -1)
        // false - database isn't around
    else
        // actual error, do something about it
})

With other drivers, you can attempt to make a connection and if it fails, you know the mongo server's down. Mongoskin needs to actually make some call (like ping) because it connects lazily. For php, you can use the try-to-connect method. Make a script!

PHP:

$dbIsRunning = true
try {
  $m = new MongoClient('localhost:27017');
} catch($e) {
  $dbIsRunning = false
}

String query = "INSERT INTO ....";
PreparedStatement preparedStatement = connection.prepareStatement(query, PreparedStatement.RETURN_GENERATED_KEYS);

preparedStatement.setXXX(1, VALUE); 
preparedStatement.setXXX(2, VALUE); 
....
preparedStatement.executeUpdate();  

ResultSet rs = preparedStatement.getGeneratedKeys();  
int key = rs.next() ? rs.getInt(1) : 0;

if(key!=0){
    System.out.println("Generated key="+key);
}

I am adding this answer in case someone else would like to store the host entry set in a txt file formatted like the normal host file. This looks for a TAB delimiter. This is based off of the answers from @Rashy and @that0n3guy. The differences can be noticed around the FOR command.

Although a more optimal solution is to simply recompile as suggested above, that requires access to the source code. In my case, I only had the finished .exe and had to use this solution. It uses CorFlags.exe from the .Net SDK to change the loading characteristics of the application.

1. Download the .Net Framework SDK (I personally used 3.5, but the version used should be at or above the required .Net for your application.
2. When installing, all you need is CorLibs.exe, so just check Windows Development Tools.
3. After installation, find your CorFlags.exe. For my install of the .Net Framework 3.5 SDK, it was at C:\Program Files\Microsoft SDKs\Windows\v7.0\Bin.
4. Open a command prompt and type path/to/CorFlags.exe path/to/your/exeFile.exe /32Bit+.

You're done! This sets the starting flags for your program so that it starts in 32 bit WOW64 mode, and can therefore access microsoft.jet.oledb.4.0.

you can easily solve it by doing following steps :

open iis manager and choose your site you wish to deploy(from the left side treeview panel) and then double click application setting icon to open application setting dialogue and then you should see a grid view on screen so double click on the row named webpages:Enabled and the set value to true (which is false by default).

it worked for me because before I did that I received the same error I even enabled directory browsing (as official iis guide recommended in iis forum) but when I browsed the site sow a list of directories rather than actual web page but when I did the steps above the problem solved and every thing worked fine(but dont forget to grant access for asppool in sql logins after solving this problem of course)

as I said it worked well for me I hope it works well for you too good luck

To resolve this problem, you can try this.

first, you have found out your pg_hba.conf by:

cd /etc/postgresql/9.5/main from your root directory

and open file using

sudo nano pg_hba.conf

then add this line:

local   all         all                               md5

to your pg_hba.conf and then restart by using the command:

sudo service postgresql restart

Use the ExecuteStoreQuery method of the entity context. This avoids downloading the entire result set and deserializing into objects to do a simple row count.

   int count;

    using (var db = new MyDatabase()){
      string sql = "SELECT COUNT(*) FROM MyTable where FkId = {0}";

      object[] myParams = {1};
      var cntQuery = db.ExecuteStoreQuery<int>(sql, myParams);

      count = cntQuery.First<int>();
    }

I'm not sure there's any official definition of these two terms. I understand an API to be a set of documented programmable libraries and supporting source such as headers or IDL files. SDKs usually contain APIs but often often add compilers, tools, and samples to the mix.

You can always find out the location of the tnsnames.ora file being used by running TNSPING to check connectivity (9i or later):

C:\>

Sometimes, the problem is with the entry you made in tnsnames.ora, not that the system can't find it. That said, I agree that having a tns_admin environment variable set is a Good Thing, since it avoids the inevitable issues that arise with determining exactly which tnsnames file is being used in systems with multiple oracle homes.

How to set the value of a pandas column as list

I would argue instead of testing i less than elements.length - 1 testing i + 1 less than elements.length. You aren't changing the domain of the array that you are looking at (i.e. ignoring the last element), but rather changing the greatest element you are looking at in each iteration.

String[] elements = { "a", "a","a","a" };

for(int i = 0; i + 1 < elements.length; i++) {
    String first = elements[i];
    String second = elements[i+1];
    //do something with the two strings
}

Thanks everyone (specially @plalx)

I find it quite overkill enforce the validity of the href attribute with such a complex and cryptic pattern while a simple expression such as
<a\s+(?:[^>]*?\s+)?href="([^"]*)"
would suffice to capture all URLs. If you want to make sure they contain at least a query string, you could just use
<a\s+(?:[^>]*?\s+)?href="([^"]+\?[^"]+)"

my choice is

If you are trying to use a variable value in the expression, you must use the RegExp "constructor".

var regex="(?!(?:[^<]+>|[^>]+<\/a>))\b(" + value + ")\b";
new RegExp(regex, "is")

To convert it to a single dictionary with some decided keys value, you can use the code below.

data = ListOfDict.copy()
PrecedingText = "Obs_"
ListOfDictAsDict = {}
for i in range(len(data)):
    ListOfDictAsDict[PrecedingText + str(i)] = data[i]

Other alternative:

JAXBElement<String> element = new JAXBElement<>(new QName("Your localPart"),
                                                String.class, "Your message");

Then:

System.out.println(element.getValue()); // Result: Your message

If I correctly understood your use case, I suggest to try using svn add to put the new folder under version, see here. The following will add the new folder with files recursively under version control (if you are inside valid working copy):

svn add new_folder
svn commit -m "Add New folder to the project"

If you are not in a working copy, create it with svn checkout, copy new_folder there and do the above steps.

OR

Try svn import, see here; the following will create a new folder and upload files to the repository:

svn import -m "Import new folder to the project" new_folder \
        http://SVN_REPO/repos/trunk/new_folder

Also note that:

After importing data, note that the original tree is not under version control. To start working, you still need to svn checkout a fresh working copy of the tree

For example this plugIns:

• https://github.com/rrethy/vim-illuminate

• https://github.com/itchyny/vim-cursorword

Just search for under cursor in vimawesome.com

The key, as clagccs mentioned, is that the highlight does NOT conflict with your search: https://vim.fandom.com/wiki/Auto_highlight_current_word_when_idle

Screen-shot of how it does NOT conflict with search: Notes:

• vim-illuminate highlights by default, in my screen-shot I switched to underline
• vim-illuminate highlights/underlines word under cursor by default, in my screen-shot I unset it
• my colorschemes are very grey-ish. Check yours to customize it too.

There is a simple solution that seems to work well for avoiding mistakes.

Simply remove the [user] section from your ~/.gitconfig, which will prevent you from making any commits without setting user.name for each repository.

In your ~/.bashrc, add some simple aliases for the user and email:

alias ggmail='git config user.name "My Name";git config user.email [email protected]'
alias gwork='git config user.name "My Name";git config user.email [email protected]'

For those of you not about that space bar life (- _ - )( - _ -)

1. Keybinding for ? Tab isn't set to anything so you have to do it manually

2. Navigate to Preferences/Environment/Keybindings and search for "tab"

3. Click on Edit Binding at the bottom and press the tab key.

4. Press "Apply" then "Ok"

5. Key bound!

I'm using this to only enable a button if a listview item is selected (ie not null):

<Style TargetType="{x:Type Button}">
    <Setter Property="IsEnabled" Value="True"/>
    <Style.Triggers>
        <DataTrigger Binding="{Binding ElementName=lvMyList, Path=SelectedItem}" Value="{x:Null}">
            <Setter Property="IsEnabled" Value="False"/>
        </DataTrigger>
    </Style.Triggers>
</Style>

Try this :

import sun.misc.IOUtils;
import java.io.IOException;

try {
    String path="";
    InputStream inputStream=new FileInputStream(path);
    byte[] data=IOUtils.readFully(inputStream,-1,false);
}
catch (IOException e) {
    System.out.println(e);
}

Your model is null because the way you're supplying the inputs to your form means the model binder has no way to distinguish between the elements. Right now, this code:

@foreach (var planVM in Model)
{
    @Html.Partial("_partialView", planVM)
}

is not supplying any kind of index to those items. So it would repeatedly generate HTML output like this:

<input type="hidden" name="yourmodelprefix.PlanID" />
<input type="hidden" name="yourmodelprefix.CurrentPlan" />
<input type="checkbox" name="yourmodelprefix.ShouldCompare" />

However, as you're wanting to bind to a collection, you need your form elements to be named with an index, such as:

<input type="hidden" name="yourmodelprefix[0].PlanID" />
<input type="hidden" name="yourmodelprefix[0].CurrentPlan" />
<input type="checkbox" name="yourmodelprefix[0].ShouldCompare" />
<input type="hidden" name="yourmodelprefix[1].PlanID" />
<input type="hidden" name="yourmodelprefix[1].CurrentPlan" />
<input type="checkbox" name="yourmodelprefix[1].ShouldCompare" />

That index is what enables the model binder to associate the separate pieces of data, allowing it to construct the correct model. So here's what I'd suggest you do to fix it. Rather than looping over your collection, using a partial view, leverage the power of templates instead. Here's the steps you'd need to follow:

1. Create an EditorTemplates folder inside your view's current folder (e.g. if your view is Home\Index.cshtml, create the folder Home\EditorTemplates).
2. Create a strongly-typed view in that directory with the name that matches your model. In your case that would be PlanCompareViewModel.cshtml.

Now, everything you have in your partial view wants to go in that template:

@model PlanCompareViewModel
<div>
    @Html.HiddenFor(p => p.PlanID)
    @Html.HiddenFor(p => p.CurrentPlan)
    @Html.CheckBoxFor(p => p.ShouldCompare)
   <input type="submit" value="Compare"/>
</div>

Finally, your parent view is simplified to this:

@model IEnumerable<PlanCompareViewModel>
@using (Html.BeginForm("ComparePlans", "Plans", FormMethod.Post, new { id = "compareForm" }))
{
<div>
    @Html.EditorForModel()
</div>
}

DisplayTemplates and EditorTemplates are smart enough to know when they are handling collections. That means they will automatically generate the correct names, including indices, for your form elements so that you can correctly model bind to a collection.

You could use a simple array intersection, this way you can know what differs in each hash.

    hash1 = { a: 1 , b: 2 }
    hash2 = { a: 2 , b: 2 }

    overlapping_elements = hash1.to_a & hash2.to_a

    exclusive_elements_from_hash1 = hash1.to_a - overlapping_elements
    exclusive_elements_from_hash2 = hash2.to_a - overlapping_elements

with maven it is automatic:

I had read some of the responses and they didn't seem to work for me. I am using Typescript 2.9.2, Angular 6 and trying to import JSON in a Jasmine Unit Test. This is what did the trick for me.

Add:

"resolveJsonModule": true,

To tsconfig.json

Import like:

import * as nameOfJson from 'path/to/file.json';

Stop ng test, start again.

Reference: https://blogs.msdn.microsoft.com/typescript/2018/05/31/announcing-typescript-2-9/#json-imports

You can add a form onsubmit handler, something like:

<form onsubmit="return validate();">

</form>


<script>function validate() {
 // check if input is bigger than 3
 var value = document.getElementById('titleeee').value;
 if (value.length < 3) {
   return false; // keep form from submitting
 }

 // else form is good let it submit, of course you will 
 // probably want to alert the user WHAT went wrong.

 return true;
}</script>

I just added H:i:s to Rocket's answer to get the time along with the date.

echo date('m/d/Y H:i:s', 1299446702);

Output: 03/06/2011 16:25:02

System.out.println(isLeapYear);

should work just fine.

Incidentally, in

else if ((year % 4 == 0) && (year % 100 == 0))
    isLeapYear = false;

else if ((year % 4 == 0) && (year % 100 == 0) && (year % 400 == 0))
    isLeapYear = true;

the year % 400 part will never be reached because if (year % 4 == 0) && (year % 100 == 0) && (year % 400 == 0) is true, then (year % 4 == 0) && (year % 100 == 0) must have succeeded.

Maybe swap those two conditions or refactor them:

else if ((year % 4 == 0) && (year % 100 == 0))
    isLeapYear = (year % 400 == 0);

If you're checking for a function that is a jQuery plugin, you need to use $.fn.myfunction

if (typeof $.fn.mask === 'function') {
    $('.zip').mask('00000');
}

Instead of CharSet.forName, using com.google.common.base.Charsets from Google's Guava (http://code.google.com/p/guava-libraries/wiki/StringsExplained#Charsets) is is slightly nicer:

InputStream is = new ByteArrayInputStream( myString.getBytes(Charsets.UTF_8) );

Which CharSet you use depends entirely on what you're going to do with the InputStream, of course.

The problem in my case was that the Nginx web server was running as user nginx and the pool was running as user www-data.

I solved the issue by changing the user Nginx is running at in the /etc/nginx/nginx.conf file (could be different on your system, mine is Ubuntu 16.04.1)

Change: user nginx;

to: user www-data;

then restart Nginx: service nginx restart

First, and most important - all Spring beans are managed - they "live" inside a container, called "application context".

Second, each application has an entry point to that context. Web applications have a Servlet, JSF uses a el-resolver, etc. Also, there is a place where the application context is bootstrapped and all beans - autowired. In web applications this can be a startup listener.

Autowiring happens by placing an instance of one bean into the desired field in an instance of another bean. Both classes should be beans, i.e. they should be defined to live in the application context.

What is "living" in the application context? This means that the context instantiates the objects, not you. I.e. - you never make new UserServiceImpl() - the container finds each injection point and sets an instance there.

In your controllers, you just have the following:

@Controller // Defines that this class is a spring bean
@RequestMapping("/users")
public class SomeController {

    // Tells the application context to inject an instance of UserService here
    @Autowired
    private UserService userService;

    @RequestMapping("/login")
    public void login(@RequestParam("username") String username,
           @RequestParam("password") String password) {

        // The UserServiceImpl is already injected and you can use it
        userService.login(username, password);

    }
}

A few notes:

• In your applicationContext.xml you should enable the <context:component-scan> so that classes are scanned for the @Controller, @Service, etc. annotations.
• The entry point for a Spring-MVC application is the DispatcherServlet, but it is hidden from you, and hence the direct interaction and bootstrapping of the application context happens behind the scene.
• UserServiceImpl should also be defined as bean - either using <bean id=".." class=".."> or using the @Service annotation. Since it will be the only implementor of UserService, it will be injected.
• Apart from the @Autowired annotation, Spring can use XML-configurable autowiring. In that case all fields that have a name or type that matches with an existing bean automatically get a bean injected. In fact, that was the initial idea of autowiring - to have fields injected with dependencies without any configuration. Other annotations like @Inject, @Resource can also be used.

This is for version 1.4.4

Some users reported "not working", if it doesn't work for you, please read below:

From what I've learned, the problem is related with network speed and or screen size.
When YT player starts, it collects the network speed, screen and player sizes, among other information, if the connection is slow or the screen/player size smaller than the quality requested(vq=), a lower quality video is displayed despite the option selected on vq=.

Also make sure you read the comments below.

I believe this is what you're looking for:

var press = jQuery.Event("keypress");
press.ctrlKey = false;
press.which = 40;
$("whatever").trigger(press);

From here.

I think the jQuery plugin freezeframe.js might come in handy for you. freezeframe.js is a jQuery Plugin To Automatically Pause GIFs And Restart Animating On Mouse Hover.

I guess you can easily adapt it to make it work on page load instead.

The command on OSX should be exactly the same as it is Unix under the pretty UI.

We are using akka with its camel plugin to distribute our analysis and trending processing for twimpact.com. We have to process between 50 and 1000 messages per second. In addition to multi-node processing with camel it is also used to distribute work on a single processor to multiple workers for maximum performance. Works quite well, but requires some understanding of how to handle congestions.

In some cases you can just use the flex-box property order.

Very simple:

.flex-item {
    order: 2;
}

Before you try searching for the elements within the iframe you will have to switch Selenium focus to the iframe.

Try this before searching for the elements within the iframe:

driver.switchTo().frame(driver.findElement(By.name("iFrameTitle")));

If anyone is interested in doing something like this in Swift these days, I have a start on something, although it's not perfect.

func detectDate(dateString: NSString) -> NSDate {

    var error: NSError?
    let detector: NSDataDetector = NSDataDetector.dataDetectorWithTypes(NSTextCheckingType.Date.toRaw(), error: &error)!

    if error == nil {
        var matches = detector.matchesInString(dateString, options: nil, range: NSMakeRange(0, dateString.length))

        let currentLocale = NSLocale.currentLocale()
        for match in matches {
            match.resultType == NSTextCheckingType.Date
            NSLog("Date: \(match.date.description)")
            return match.date
        }
    }
    return NSDate()
}

For anyone else who stumbles on this make sure you're not attempting to modify the class rather than the instance! (unless you've declared the variable as static)

eg.

MyClass.variable = 'Foo' // WRONG! - Instance member 'variable' cannot be used on type 'MyClass'

instanceOfMyClass.variable = 'Foo' // Right!

Done after lots of R&D:

fragment_one.xml should looks like:

<?xml version="1.0" encoding="utf-8"?>

    android:layout_width="match_parent"
    android:layout_height="match_parent"

                android:layout_width="match_parent"

        </RelativeLayout>

        <!-- Your other elements are here -->

                        scrollViewParent.requestDisallowInterceptTouchEvent(true);
                        // Disable touch on transparent view
                        return false;

                    case MotionEvent.ACTION_UP:
                        // Allow ScrollView to intercept touch events.
                        scrollViewParent.requestDisallowInterceptTouchEvent(false);

The suggested answer only works for certain versions of ruby. Some commenters suggest using ruby-dev; that didn't work for me either.

sudo apt-get install ruby-all-dev

worked for me.

This is my first post on SO, so I don't have enough reputation to comment the accepted answer, but I had to modify the code to the following:

export function focusNextElement () {
  //add all elements we want to include in our selection
  const focussableElements = 
    'a:not([disabled]), button:not([disabled]), input[type=text]:not([disabled])'
  if (document.activeElement && document.activeElement.form) {
      var focussable = Array.prototype.filter.call(
        document.activeElement.form.querySelectorAll(focussableElements),
      function (element) {
          // if element has tabindex = -1, it is not focussable
          if ( element.hasAttribute('tabindex') && element.tabIndex === -1 ){
            return false
          }
          //check for visibility while always include the current activeElement 
          return (element.offsetWidth > 0 || element.offsetHeight > 0 || 
            element === document.activeElement)
      });
      console.log(focussable)
      var index = focussable.indexOf(document.activeElement);
      if(index > -1) {
         var nextElement = focussable[index + 1] || focussable[0];
         console.log(nextElement)
         nextElement.focus()
      }                    
  }
}

The changing of var to constant is non-critical. The main change is that we get rid of the selector that checks tabindex != "-1". Then later, if the element has the attribute tabindex AND it is set to "-1", we do NOT consider it focussable.

The reason I needed to change this was because when adding tabindex="-1" to an <input>, this element was still considered focussable because it matches the "input[type=text]:not([disabled])" selector. My change is equivalent to "if we are a non-disabled text input, and we have a tabIndex attribute, and the value of that attribute is -1, then we should not be considered focussable.

I believe that when the author of the accepted answer edited their answer to account for the tabIndex attribute, they did not do so correctly. Please let me know if this is not the case

Alex mentioned memory efficiency, and Roberto mentions convenience, and these are both good points. For a few more ideas, I'll mention speed and functionality.

Functionality: You get a lot built in with NumPy, FFTs, convolutions, fast searching, basic statistics, linear algebra, histograms, etc. And really, who can live without FFTs?

Speed: Here's a test on doing a sum over a list and a NumPy array, showing that the sum on the NumPy array is 10x faster (in this test -- mileage may vary).

from numpy import arange
from timeit import Timer

Nelements = 10000
Ntimeits = 10000

x = arange(Nelements)
y = range(Nelements)

t_numpy = Timer("x.sum()", "from __main__ import x")
t_list = Timer("sum(y)", "from __main__ import y")
print("numpy: %.3e" % (t_numpy.timeit(Ntimeits)/Ntimeits,))
print("list:  %.3e" % (t_list.timeit(Ntimeits)/Ntimeits,))

which on my systems (while I'm running a backup) gives:

numpy: 3.004e-05
list:  5.363e-04

Arduino doesn't run either C or C++. It runs machine code compiled from either C, C++ or any other language that has a compiler for the Arduino instruction set.

C being a subset of C++, if Arduino can "run" C++ then it can "run" C.

If you don't already know C nor C++, you should probably start with C, just to get used to the whole "pointer" thing. You'll lose all the object inheritance capabilities though.

For those who need the input file to open directly the camera, you just have to declare capture parameter to the input file, like this :

<input type="file" accept="image/*" capture>

I tried your code and got a top rounded corner button. I gave the colors as @ffffff and stroke I gave #C0C0C0.

try

1. Giving android : bottomLeftRadius="0.1dp" instead of 0. if its not working
2. Check in what drawable and the emulator's resolution. I created a drawable folder under res and using it. (hdpi, mdpi ldpi) the folder you have this XML. this is my output.

Woo-hoo! It works with some hack!

According to this comment you need to:

1. Manually edit Microsoft.CSharp.DesignTime.targets located in C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\Microsoft\VisualStudio\Managed (for VS Community edition, modify path for other editions), append ClassDesigner value to ProjectCapability (right pane):

2. Restart VS.

3. Manually create text file, say MyClasses.cd with following content: <?xml version="1.0" encoding="utf-8"?> <ClassDiagram MajorVersion="1" MinorVersion="1"> <Font Name="Segoe UI" Size="9" /> </ClassDiagram>

Bingo. Now you may open this file in VS. You will see error message "Object reference not set to an instance of object" once after VS starts, but diagram works.

This script is about creating tables with foreign key and I added referential integrity constraint sql-server.

create table exams
(  
    exam_id int primary key,
    exam_name varchar(50),
);

create table question_bank 
(
    question_id int primary key,
    question_exam_id int not null,
    question_text varchar(1024) not null,
    question_point_value decimal,
    constraint question_exam_id_fk
       foreign key references exams(exam_id)
               ON DELETE CASCADE
);

Suppose you want to insert a particular line of text (not an empty line):

@echo off
FOR /F %%C IN ('FIND /C /V "" ^<%origfile%') DO SET totallines=%%C
set /a totallines+=1

@echo off
<%origfile% (FOR /L %%i IN (1,1,%totallines%) DO (
  SETLOCAL EnableDelayedExpansion
  SET /p L=
  IF %%i==%insertat% ECHO(!TL!
  ECHO(!L!
  ENDLOCAL
)
) >%tempfile%

COPY /Y %tempfile% %origfile% >NUL

DEL %tempfile%

If you need not only round result but elso do math operations with round result, then you can use decimal.Decimal https://docs.python.org/2/library/decimal.html

from decimal import Decimal, ROUND_DOWN

Decimal('7.325').quantize(Decimal('.01'), rounding=ROUND_DOWN)
Decimal('7.32') 

In Bash you can do it by enabling the extglob option, like this (replace ls with cp and add the target directory, of course)

~/foobar> shopt extglob
extglob        off
~/foobar> ls
abar  afoo  bbar  bfoo
~/foobar> ls !(b*)
-bash: !: event not found
~/foobar> shopt -s extglob  # Enables extglob
~/foobar> ls !(b*)
abar  afoo
~/foobar> ls !(a*)
bbar  bfoo
~/foobar> ls !(*foo)
abar  bbar

You can later disable extglob with

shopt -u extglob

Here's a method I wrote for a "run all JUnits under a package". You should be able to adapt it to your needs.

private static void findClassesInJar(List<String> classFiles, String path) throws IOException {
    final String[] parts = path.split("\\Q.jar\\\\E");
    if (parts.length == 2) {
        String jarFilename = parts[0] + ".jar";
        String relativePath = parts[1].replace(File.separatorChar, '/');
        JarFile jarFile = new JarFile(jarFilename);
        final Enumeration<JarEntry> entries = jarFile.entries();
        while (entries.hasMoreElements()) {
            final JarEntry entry = entries.nextElement();
            final String entryName = entry.getName();
            if (entryName.startsWith(relativePath)) {
                classFiles.add(entryName.replace('/', File.separatorChar));
            }
        }
    }
}

Edit: Ah, in that case, you might want this snippet as well (same use case :) )

One hexadecimal digit is of one nibble (4 bits). Two nibbles make 8 bits which are also called 1 byte.

MD5 generates a 128-bit output which is represented using a sequence of 32 hexadecimal digits, which in turn are 32*4=128 bits. 128 bits make 16 bytes (since 1 byte is 8 bits).

Each Base64 character encodes 6 bits (except the last non-pad character which can encode 2, 4 or 6 bits; and final pad characters, if any). Therefore, per Base64 encoding, a 128-bit hash requires at least ?128/6? = 22 characters, plus pad if any.

Using base64, we can produce the encoded output of our desired length (6, 8, or 10). If we choose to decide 8 char long output, it occupies only 8 bytes whereas it was occupying 16 bytes for 128-bit hash output.

So, in addition to security, base64 encoding is also used to reduce the space consumed.

None of the examples above create 8-bit (8bpp) bitmap images. Some software, such as image processing, only supports 8bpp. Unfortunately the MS .NET libraries do not have a solution. The PixelFormat.Format8bppIndexed format looks promising but after a lot of attempts I couldn't get it working.

To create a true 8-bit bitmap file you need to create the proper headers. Ultimately I found the Grayscale library solution for creating 8-bit bitmap (BMP) files. The code is very simple:

Image image = Image.FromFile("c:/path/to/image.jpg");
GrayBMP_File.CreateGrayBitmapFile(image, "c:/path/to/8bpp/image.bmp");

The code for this project is far from pretty but it works, with one little simple-to-fix problem. The author hard-coded the image resolution to 10x10. Image processing programs do not like this. The fix is open GrayBMP_File.cs (yeah, funky file naming, I know) and replace lines 50 and 51 with the code below. The example sets the resolution to 200x200 but you should change it to the proper number.

int resX = 200;
int resY = 200;
// horizontal resolution
Copy_to_Index(DIB_header, BitConverter.GetBytes(resX * 100), 24);
// vertical resolution 
Copy_to_Index(DIB_header, BitConverter.GetBytes(resY * 100), 28);

You can also use the System.Runtime.CompilerServices.Unsafe NuGet package to create a reference to the same List:

using System.Runtime.CompilerServices;
...
class Tool { }
class Hammer : Tool { }
...
var hammers = new List<Hammer>();
...
var tools = Unsafe.As<List<Tool>>(hammers);

Given the sample above, you can access the existing Hammer instances in the list using the tools variable. Adding Tool instances to the list throws an ArrayTypeMismatchException exception because tools references the same variable as hammers.

You can introduce the lineterminator='\n' parameter in the csv writer command.

import csv
delimiter='\t'
with open('tmp.csv', '+w', encoding='utf-8') as stream:
    writer = csv.writer(stream, delimiter=delimiter, quoting=csv.QUOTE_NONE, quotechar='',  lineterminator='\n')
    writer.writerow(['A1' , 'B1', 'C1'])
    writer.writerow(['A2' , 'B2', 'C2'])
    writer.writerow(['A3' , 'B3', 'C3'])

Summarizing the solutions, I think that's the best one:

boolean isUiThread = VERSION.SDK_INT >= VERSION_CODES.M 
    ? Looper.getMainLooper().isCurrentThread()
    : Thread.currentThread() == Looper.getMainLooper().getThread();

And, if you wish to run something on the UI thread, you can use this:

new Handler(Looper.getMainLooper()).post(new Runnable() {
    @Override
    public void run() {
       //this runs on the UI thread
    }
});

While you may wish to use a library, such as the excellent jQuery, you don't have to: all modern browsers support HTTP very well in their JavaScript implementations via the XMLHttpRequest API, which, despite its name, is not limited to XML representations.

Here's an example of making a synchronous HTTP PUT request in JavaScript:

var url = "http://host/path/to/resource";
var representationOfDesiredState = "The cheese is old and moldy, where is the bathroom?";

var client = new XMLHttpRequest();

client.open("PUT", url, false);

client.setRequestHeader("Content-Type", "text/plain");

client.send(representationOfDesiredState);

if (client.status == 200)
    alert("The request succeeded!\n\nThe response representation was:\n\n" + client.responseText)
else
    alert("The request did not succeed!\n\nThe response status was: " + client.status + " " + client.statusText + ".");

This example is synchronous because that makes it a little easier, but it's quite easy to make asynchronous requests using this API as well.

There are thousands of pages and articles on the web about learning XmlHttpRequest — they usually use the term AJAX – unfortunately I can't recommend a specific one. You may find this reference handy though.

select empno
       ,salary
       ,row_number() over(order by salary desc) as Serial
       ,Rank() over(order by salary desc) as rank
       ,dense_rank() over(order by salary desc) as denseRank
from emp ;

Row_number() -> Used for generating serial number

Dense_rank() will give continuous rank but rank will skip rank in case of clash of rank.

Try this: String.format("%.2f", angle);

Here I come with this solution inspired by @Kemal Karadag.

I noticed that every solution posted here is relying on the focus,

While I wanted my placeholder to be the exact clone of a standard HTML placeholder in Google Chrome.

Instead of hiding/showing the placeholder when the box is focused,

I hide/show the placeholder depending on the text length of the box:

If the box is empty, the placeholder is shown, and if you type in the box, the placeholder disappears.

As it is inherited from a standard TextBox, you can find it in your Toolbox!

using System;
using System.Drawing;
using System.Windows.Forms;

public class PlaceHolderTextBox : TextBox
{
    private bool isPlaceHolder = true;
    private string placeHolderText;

    public string PlaceHolderText
    {
        get { return placeHolderText; }
        set
        {
            placeHolderText = value;
            SetPlaceholder();
        }
    }

    public PlaceHolderTextBox()
    {
        TextChanged += OnTextChanged;
    }

    private void SetPlaceholder()
    {
        if (!isPlaceHolder)
        {
            this.Text = placeHolderText;
            this.ForeColor = Color.Gray;
            isPlaceHolder = true;
        }
    }

    private void RemovePlaceHolder()
    {
        if (isPlaceHolder)
        {
            this.Text = this.Text[0].ToString(); // Remove placeHolder text, but keep the character we just entered
            this.Select(1, 0); // Place the caret after the character we just entered
            this.ForeColor = System.Drawing.SystemColors.WindowText;
            isPlaceHolder = false;
        }
    }

    private void OnTextChanged(object sender, EventArgs e)
    {
        if (this.Text.Length == 0)
        {
            SetPlaceholder();
        }
        else
        {
            RemovePlaceHolder();
        }
    }
}

For larger data sets where sorting may not be desirable, you can also use the following perl script:

./yourscript.ksh | perl -ne 'if (!defined $x{$_}) { print $_; $x{$_} = 1; }'

This basically just remembers every line output so that it doesn't output it again.

It has the advantage over the "sort | uniq" solution in that there's no sorting required up front.

Avoid testing with parallel threads whenever you can (which is most of the time). This will only make your tests flaky (sometimes pass, sometimes fail).

Only when you need to call some other library / system, you might have to wait on other threads, in that case always use the Awaitility library instead of Thread.sleep().

Never just call get() or join() in your tests, else your tests might run forever on your CI server in case the future never completes. Always assert isDone() first in your tests before calling get(). For CompletionStage, that is .toCompletableFuture().isDone().

When you test a non-blocking method like this:

public static CompletionStage<String> createGreeting(CompletableFuture<String> future) {
    return future.thenApply(result -> "Hello " + result);
}

then you should not just test the result by passing a completed Future in the test, you should also make sure that your method doSomething() does not block by calling join() or get(). This is important in particular if you use a non-blocking framework.

To do that, test with a non-completed future that you set to completed manually:

@Test
public void testDoSomething() throws Exception {
    CompletableFuture<String> innerFuture = new CompletableFuture<>();
    CompletableFuture<String> futureResult = createGreeting(innerFuture).toCompletableFuture();
    assertFalse(futureResult.isDone());

    // this triggers the future to complete
    innerFuture.complete("world");
    assertTrue(futureResult.isDone());

    // futher asserts about fooResult here
    assertEquals(futureResult.get(), "Hello world");
}

That way, if you add future.join() to doSomething(), the test will fail.

If your Service uses an ExecutorService such as in thenApplyAsync(..., executorService), then in your tests inject a single-threaded ExecutorService, such as the one from guava:

ExecutorService executorService = Executors.newSingleThreadExecutor();

If your code uses the forkJoinPool such as thenApplyAsync(...), rewrite the code to use an ExecutorService (there are many good reasons), or use Awaitility.

To shorten the example, I made BarService a method argument implemented as a Java8 lambda in the test, typically it would be an injected reference that you would mock.

It doesn't work because name is a reserved word in JavaScript. Change the function name to something else.

See http://www.quackit.com/javascript/javascript_reserved_words.cfm

<form id="form" onsubmit="return false;">
    <input style="position:absolute; top:80%; left:5%; width:40%;" type="text" id="userInput" />
    <input style="position:absolute; top:50%; left:5%; width:40%;" type="submit" onclick="othername();" />
</form>

function othername() {
    var input = document.getElementById("userInput").value;
    alert(input);
}

Why not just use the literal characters?

fig.gca().set_xlabel("wavelength, (Å)")
fig.gca().set_ylabel("?")

You might have to add this to the file if you are using python 2:

# -*- coding: utf-8 -*-
from __future__ import unicode literals  # or use u"unicode strings"

It might be easier to define constants for characters that are not easy to type on your keyboard.

ANGSTROM, LAMDBA = "Å?"

Then you can reuse them elsewhere.

fig.gca().set_xlabel("wavelength, (%s)" % ANGSTROM)
fig.gca().set_ylabel(LAMBDA)

Another way based on amadan:

    SELECT * FROM [Purchasing].[Vendor] WHERE  

      ( (@url IS null OR @url = '' OR @url = 'ALL') and   PurchasingWebServiceURL LIKE '%')
    or

       ( @url = 'blank' and  PurchasingWebServiceURL = '')
    or
        (@url = 'fail' and  PurchasingWebServiceURL NOT LIKE '%treyresearch%')
    or( (@url not in ('fail','blank','','ALL') and @url is not null and 
          PurchasingWebServiceUrl Like '%'+@ur+'%') 
END

Profile pictures are scaled down to 125x125 on the facebook sever when they're uploaded, so as far as I know you can't get pictures bigger than that. How big is the picture you're getting?

You are opening the csv file in binary mode, it should be 'w'

import csv

# open csv file in write mode with utf-8 encoding
with open('output.csv','w',encoding='utf-8',newline='')as w:
    fieldnames = ["SNo", "States", "Dist", "Population"]
    writer = csv.DictWriter(w, fieldnames=fieldnames)
    # write list of dicts
    writer.writerows(list_of_dicts) #writerow(dict) if write one row at time

HttpHandler Example,

HTTP Handler in ASP.NET 2.0

A handler is responsible for fulfilling requests from a browser. Requests that a browser manages are either handled by file extension or by calling the handler directly.The low level Request and Response API to service incoming Http requests are Http Handlers in Asp.Net. All handlers implement the IHttpHandler interface, which is located in the System.Web namespace. Handlers are somewhat analogous to Internet Server Application Programming Interface (ISAPI) extensions.

You implement the IHttpHandler interface to create a synchronous handler and the IHttpAsyncHandler interface to create an asynchronous handler. The interfaces require you to implement the ProcessRequest method and the IsReusable property. The ProcessRequest method handles the actual processing for requests made, while the Boolean IsReusable property specifies whether your handler can be pooled for reuse to increase performance or whether a new handler is required for each request.

The .ashx file extension is reserved for custom handlers. If you create a custom handler with a file name extension of .ashx, it will automatically be registered within IIS and ASP.NET. If you choose to use an alternate file extension, you will have to register the extension within IIS and ASP.NET. The advantage of using an extension other than .ashx is that you can assign multiple file extensions to one handler.

Configuring HTTP Handlers

The configuration section handler is responsible for mapping incoming URLs to the IHttpHandler or IHttpHandlerFactory class. It can be declared at the computer, site, or application level. Subdirectories inherit these settings. Administrators use the tag directive to configure the section. directives are interpreted and processed in a top-down sequential order. Use the following syntax for the section handler:

Creating HTTP Handlers

To create an HTTP handler, you must implement the IHttpHandler interface. The IHttpHandler interface has one method and one property with the following signatures: void ProcessRequest(HttpContext); bool IsReusable {get;}

For those who are using this format all the timme like me I did an extension method. I just wanted to share because I think it can be usefull to you.

     /// <summary>
    /// Convert a date to a human readable ISO datetime format. ie. 2012-12-12 23:01:12
    /// this method must be put in a static class. This will appear as an available function
    /// on every datetime objects if your static class namespace is declared.
    /// </summary>
    public static string ToIsoReadable(this DateTime dateTime)
    {
        return dateTime.ToString("yyyy-MM-dd HH':'mm':'ss");
    }

I have come to point out the answer nobody seems to see here. You can fullfill all requests you have made with pure CSS and it's very simple. Just use Media Queries. Media queries can check the orientation of the user's screen, or viewport. Then you can style your images depending on the orientation.

Just set your default CSS on your images like so:

img {
   width:auto;
   height:auto;
   max-width:100%;
   max-height:100%;
}

Then use some media queries to check your orientation and that's it!

@media (orientation: landscape) { img { height:100%; } }
@media (orientation: portrait) { img { width:100%; } }

You will always get an image that scales to fit the screen, never loses aspect ratio, never scales larger than the screen, never clips or overflows.

To learn more about these media queries, you can read MDN's specs.

Centering

To center your image horizontally and vertically, just use the flex box model. Use a parent div set to 100% width and height, like so:

div.parent {
   display:flex;
   position:fixed;
   left:0px;
   top:0px;
   width:100%;
   height:100%;
   justify-content:center;
   align-items:center;
}

With the parent div's display set to flex, the element is now ready to use the flex box model. The justify-content property sets the horizontal alignment of the flex items. The align-items property sets the vertical alignment of the flex items.

Conclusion

I too had wanted these exact requirements and had scoured the web for a pure CSS solution. Since none of the answers here fulfilled all of your requirements, either with workarounds or settling upon sacrificing a requirement or two, this solution really is the most straightforward for your goals; as it fulfills all of your requirements with pure CSS.

EDIT: The accepted answer will only appear to work if your images are large. Try using small images and you will see that they can never be larger than their original size.

I ran into this error as well for a while. I think (hope) I've wrapped my head around it, wanted to write it here for reference.

When you add middleware to connect or express (which is built on connect) using the app.use method, you're appending items to Server.prototype.stack in connect (At least with the current npm install connect, which looks quite different from the one github as of this post). When the server gets a request, it iterates over the stack, calling the (request, response, next) method.

The problem is, if in one of the middleware items writes to the response body or headers (it looks like it's either/or for some reason), but doesn't call response.end() and you call next() then as the core Server.prototype.handle method completes, it's going to notice that:

1. there are no more items in the stack, and/or
2. that response.headerSent is true.

So, it throws an error. But the error it throws is just this basic response (from the connect http.js source code:

res.statusCode = 404;
res.setHeader('Content-Type', 'text/plain');
res.end('Cannot ' + req.method + ' ' + req.url);

Right there, it's calling res.setHeader('Content-Type', 'text/plain');, which you are likely to have set in your render method, without calling response.end(), something like:

response.setHeader("Content-Type", "text/html");
response.write("<p>Hello World</p>");

The way everything needs to be structured is like this:

Good Middleware

// middleware that does not modify the response body
var doesNotModifyBody = function(request, response, next) {
  request.params = {
    a: "b"
  };
  // calls next because it hasn't modified the header
  next();
};

// middleware that modify the response body
var doesModifyBody = function(request, response, next) {
  response.setHeader("Content-Type", "text/html");
  response.write("<p>Hello World</p>");
  response.end();
  // doesn't call next()
};

app.use(doesNotModifyBody);
app.use(doesModifyBody);

Problematic Middleware

var problemMiddleware = function(request, response, next) {
  response.setHeader("Content-Type", "text/html");
  response.write("<p>Hello World</p>");
  next();
};

The problematic middleware sets the response header without calling response.end() and calls next(), which confuses connect's server.

First thing first. set the column in which you are working in by clicking on format cells->number-> date and then format e.g Jan-16 representing Jan, 1, 2016. and then apply either of the formulas above.

One problem with option 1 in answer from Victor Zamanian is that if the type isn't exported then users of your package can't declare it as the type for function parameters etc. One way around this would be to export an interface instead of the struct e.g.

package candidate
// Exporting interface instead of struct
type Candidate interface {}
// Struct is not exported
type candidate struct {
    Name string
    Votes uint32 // Defaults to 0
}
// We are forced to call the constructor to get an instance of candidate
func New(name string) Candidate {
    return candidate{name, 0}  // enforce the default value here
}

Which lets us declare function parameter types using the exported Candidate interface. The only disadvantage I can see from this solution is that all our methods need to be declared in the interface definition, but you could argue that that is good practice anyway.

You should use CALL

CALL batch.bat

You can view which modules (compiled in) are available via terminal through php -m

$<?
$db = sqlite_open('mysqlitedb');
$cols = sqlite_fetch_column_types('form name'$db, SQLITE_ASSOC);
foreach ($cols as $column => $type) {
  echo "Column: $column  Type: $type\n";
}

Not sure why no one has mentioned two Base R functions specifically to do this: str2lang() and str2expression(). These are variants of parse(), but seem to return the expression more cleanly:

eval(str2lang("5+5"))

# > 10
  
eval(str2expression("5+5"))

# > 10

Also want to push back against the posters saying that anyone trying to do this is wrong. I'm reading in R expressions stored as text in a file and trying to evaluate them. These functions are perfect for this use case.

Update 15.11.2017

It seems that by now it is working like one would expect. Running the following commands using the following pip and python version should work.

Installing with Python 3.6.x

Version

Python: 3.6.3
pip: 9.0.1

Installation Commands

The following commands are based of the following installation guide here.

using cmd

C:> pip3 install --upgrade tensorflow // cpu
C:> pip3 install --upgrade tensorflow-gpu // gpu

using Anaconda

C:> conda create -n tensorflow python=3.5 
C:> activate tensorflow
(tensorflow)C:> pip install --ignore-installed --upgrade tensorflow
(tensorflow)C:> pip install --ignore-installed --upgrade tensorflow-gpu 

Additional Information

You can find an example console output of a successful tensorflow cpu installation here.

Old response:

Okay to conclude; use version 3.5.2 !
Neither 3.5.1 nor 3.6.x seem to work at the moment.

// cpu
C:> pip install --upgrade https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-0.12.0rc0-cp35-cp35m-win_amd64.whl

// gpu
C:> pip install --upgrade https://storage.googleapis.com/tensorflow/windows/gpu/tensorflow_gpu-0.12.0rc0-cp35-cp35m-win_amd64.whl

Use the string's constructor

basic_string(const charT* s,size_type n, const Allocator& a = Allocator());

EDIT:

OK, then if the C string length is not given explicitly, use the ctor:

basic_string(const charT* s, const Allocator& a = Allocator());

It's worth noting that if your error is due to .htaccess, for example a missing rewrite_module, you'll still see the 500 internal server error.

Use:

((Long) userService.getAttendanceList(currentUser)).intValue();

instead.

The .intValue() method is defined in class Number, which Long extends.

Using Date object guarantees that. For eg if you try to create April 31st :

new Date(2014,3,31)        // Thu May 01 2014 00:00:00

Please note that it's zero indexed, so Jan. is 0, Feb. is 1 etc.

I found This simpler yet powerful tutorial which uses the fileReader Object. It simply creates an img element and, using the fileReader object, assigns its source attribute as the value of the form input

function previewFile() {_x000D_
  var preview = document.querySelector('img');_x000D_
  var file    = document.querySelector('input[type=file]').files[0];_x000D_
  var reader  = new FileReader();_x000D_
_x000D_
  reader.onloadend = function () {_x000D_
    preview.src = reader.result;_x000D_
  }_x000D_
_x000D_

    reader.readAsDataURL(file);_x000D_
  } else {_x000D_
    preview.src = "";_x000D_
  }_x000D_
}

<input type="file" onchange="previewFile()"><br>_x000D_
<img src="" height="200" alt="Image preview...">

Why not simply

var item = $('.field-item');
for (var i = 0; i <= item.length; i++) {
       if ($(item[i]).text() == 'someText') {
             $(item[i]).addClass('thisClass');
             //do some other stuff here
          }
     }

Pages are intended for use in Navigation applications (usually with Back and Forward buttons, e.g. Internet Explorer). Pages must be hosted in a NavigationWindow or a Frame

Windows are just normal WPF application Windows, but can host Pages via a Frame container

I totally agree with Abacus (sorry - don't have enough points to comment).

Also, keep in mind it doesn't necessarily come down to how many records you have, but the size of your records.

For instance, have you considered the performance difference between 1,000 records with 50 columns each vs 100,000 records with only 5 columns each?

Lastly, maybe you're querying/storing more data than you need? Here's a good read on SQL optimization strategies. Limit the amount of data you're pulling, especially if you're not using it all (some SQL programmers do get lazy and just select everything even though they only use a tiny subset). Don't forget the SQL query analyzer may also become your best friend.

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

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

In python 3.7 and above there is a new and easy way. here is the syntax:

name = "Eric"
age = 74
f"Hello, {name}. You are {age}."

OutPut:

Hello, Eric. You are 74.

A simplified shortcut I've tried is this:

    int x[] = {1,2,3};
    String printableText = Arrays.toString(x).replaceAll("[\\[\\]]", "").replaceAll(", ", "\n");
    System.out.println(printableText);

It will print

1
2
3

No loops required in this approach and it is best for small arrays only

you can do this :

declare @rowCount int
exec yourStoredProcedureName @outputparameterspOf = @rowCount output

Q. When is the "with grant option" required ?

A. when you have a view executed from a third schema.

Example: schema DSDSW has a view called view_name

a) that view selects from a table in another schema  (FDR.balance)
b) a third shema  X_WORK  tries to select  from that view

Typical grants: grant select on dsdw.view_name to dsdw_select_role; grant dsdw_select_role to fdr;

But: fdr gets select count(*) from dsdw.view_name; ERROR at line 1: ORA-01031: insufficient privileges

issue the grant:

grant select on fdr.balance to dsdw with grant option;

now fdr: select count(*) from dsdw.view_name; 5 rows

For Example:

var x = 9.656;
x.toFixed(0);           // returns 10
x.toFixed(2);           // returns 9.66
x.toFixed(4);           // returns 9.6560
x.toFixed(6);           // returns 9.656000 

or

parseInt("10");         // returns 10
parseInt("10.33");      // returns 10
parseInt("10 20 30");   // returns 10
parseInt("10 years");   // returns 10
parseInt("years 10");   // returns NaN  

Yes :). Try this:

DECLARE @text AS NVARCHAR(10)

SET @text = '100'
SELECT CASE WHEN ISNUMERIC(@text) = 1 THEN CAST(@text AS INT) ELSE NULL END
-- returns 100

SET @text = 'XXX'
SELECT CASE WHEN ISNUMERIC(@text) = 1 THEN CAST(@text AS INT) ELSE NULL END
-- returns NULL

ISNUMERIC() has a few issues pointed by Fedor Hajdu.

It returns true for strings like $ (is currency), , or . (both are separators), + and -.

Generic way to update the any JSONObjet with new values.

private static void updateJsonValues(JsonObject jsonObj) {
    for (Map.Entry<String, JsonElement> entry : jsonObj.entrySet()) {
        JsonElement element = entry.getValue();
        if (element.isJsonArray()) {
            parseJsonArray(element.getAsJsonArray());
        } else if (element.isJsonObject()) {
            updateJsonValues(element.getAsJsonObject());
        } else if (element.isJsonPrimitive()) {
            jsonObj.addProperty(entry.getKey(), "<provide new value>");
        }

    }
}

private static void parseJsonArray(JsonArray asJsonArray) {
    for (int index = 0; index < asJsonArray.size(); index++) {
        JsonElement element = asJsonArray.get(index);
        if (element.isJsonArray()) {
            parseJsonArray(element.getAsJsonArray());
        } else if (element.isJsonObject()) {
            updateJsonValues(element.getAsJsonObject());
        }

    }
}

all the solutions are not working with server-side or in angular universal

you never change the value of rng so it always points to the initial cell

copy the Set rng = rng.Offset(1, 0) to a new line before loop

also, your InStr test will always fail
True is -1, but the return from InStr will be greater than 0 when the string is found. change the test to remove = True

new code:

Sub IfTest()
 'This should split the information in a table up into cells
 Dim Splitter() As String
 Dim LenValue As Integer     'Gives the number of characters in date string
 Dim LeftValue As Integer    'One less than the LenValue to drop the ")"
 Dim rng As Range, cell As Range
 Set rng = ActiveCell

Do While ActiveCell.Value <> Empty
    If InStr(rng, "%") Then
        ActiveCell.Offset(0, 0).Select
        Splitter = Split(ActiveCell.Value, "% Change")
        ActiveCell.Offset(0, 10).Select
        ActiveCell.Value = Splitter(1)
        ActiveCell.Offset(0, -1).Select
        ActiveCell.Value = "% Change"
        ActiveCell.Offset(1, -9).Select
    Else
        ActiveCell.Offset(0, 0).Select
        Splitter = Split(ActiveCell.Value, "(")
        ActiveCell.Offset(0, 9).Select
        ActiveCell.Value = Splitter(0)
        ActiveCell.Offset(0, 1).Select
        LenValue = Len(Splitter(1))
        LeftValue = LenValue - 1
        ActiveCell.Value = Left(Splitter(1), LeftValue)
        ActiveCell.Offset(1, -10).Select
    End If
Set rng = rng.Offset(1, 0)
Loop

End Sub

The only way I've seen it done is if you do this:

for /f "delims=" %a in ('ver') do @set foobar=%a

ver is the version command for Windows and on my system it produces:

Microsoft Windows [Version 6.0.6001]

you can use :

 public static void ReadFileToEnd()
{
    try
    {
    //provide to reader your complete text file
        using (StreamReader sr = new StreamReader("TestFile.txt"))
        {
            String line = sr.ReadToEnd();
            Console.WriteLine(line);
        }
    }
    catch (Exception e)
    {
        Console.WriteLine("The file could not be read:");
        Console.WriteLine(e.Message);
    }
}

DataFrames are based on RDDs. RDDs are immutable structures and do not allow updating elements on-site. To change values, you will need to create a new DataFrame by transforming the original one either using the SQL-like DSL or RDD operations like map.

A highly recommended slide deck: Introducing DataFrames in Spark for Large Scale Data Science.

As mentionned here, I've made it work with some ":before" pseudo-class and a small bit of javascript. Here is the idea :

 #myInput:before{ content:"Date of birth"; width:100%; color:#AAA; } 
 #myInput:focus:before,
 #myInput.not_empty:before{ content:none }

Then in javascript, add the "not_empty" class depending on the value in the onChange and onKeyUp events.

You can even add all of this dynamically on every date fields. Check my answer on the other thread for the code.

It's not perfect but it's working well in Chrome and iOS7 webviews. Maybe it could help you.

 public List<tbltask> gettaskssdata(int? c, int? userid, string a, string StartDate, string EndDate, int? ProjectID, int? statusid)_x000D_
        {_x000D_
            List<tbltask> tbtask = new List<tbltask>();_x000D_
            DateTime sdate = (StartDate != "") ? Convert.ToDateTime(StartDate).Date : new DateTime();_x000D_
            DateTime edate = (EndDate != "") ? Convert.ToDateTime(EndDate).Date : new DateTime();_x000D_
            tbtask = entity.tbltasks.Include(x => x.tblproject).Include(x => x.tbUser)._x000D_
                Where(x => x.tblproject.company_id == c_x000D_
                    && (ProjectID == 0 || ProjectID == x.tblproject.ProjectId)_x000D_
                    && (statusid == 0 || statusid == x.tblstatu.StatusId)_x000D_
                    && (a == "" || (x.TaskName.Contains(a) || x.tbUser.User_name.Contains(a)))_x000D_
                    && ((StartDate == "" && EndDate == "") || ((x.StartDate >= sdate && x.EndDate <= edate)))).ToList();_x000D_
_x000D_
_x000D_
_x000D_
            return tbtask;_x000D_
_x000D_
_x000D_
        }

this my query for search records based on searchdata and between start to end date

Actually, the following works fine for me and creates new windows:

test.cmd:

@echo off
start test2.cmd
start test3.cmd
echo Foo
pause

test2.cmd

@echo off
echo Test 2
pause
exit

test3.cmd

@echo off
echo Test 3
pause
exit

Combine that with parameters to start, such as /min, as Moshe pointed out if you don't want the new windows to spawn in front of you.

In .Net, you cannot assign a null value to an int or any other struct. Instead, use a Nullable<int>, or int? for short:

int? value = 0;

if (value == 0)
{
    value = null;
}

Like many others, I've encountered numerous problems trying to do this, and only a combination of the solutions posted, and eventually a big hack to make it perfect, has landed me a solution.

Problems with other solutions in this thread that I've tried:

1. Selecting a new date in a datepicker, would also change the (internal) date of other datepickers, so when you opened the other ones again (or tried getting their date), they would have a different date than the one displayed in their assigned input-field.
2. The datepicker wouldn't "remember" the date when opened again.
3. The code for juggling the dates used substringing so it wasn't compatible with all formats.
4. "My monthpicker" only changed the input-field on closing it, rather than whenever the values were changed.
5. The input-field isn't updated correctly, if you type in a wrongly formatted input-string for a date, and then click 'Close' on the datepicker.
6. I can't have normal datepickers, which show the days, on the same page as monthpickers, which don't show the days.

I've finally found a way to fix all of these problems. The first four can be fixed simply by being careful about how you reference your date- and monthpickers in their internal code, and of course doing some manual updating of your pickers. This you can see in the instantiation-examples near the bottom. The fifth problem can be helped by adding some custom code to the datepicker functions.

NOTE: You do NOT need to use the following monthpicker scripts to fix the first three problems in your normal datepicker. Simply use the datepicker instantiation-script near the bottom of this post.

Now, to use monthpickers and mend the last problem, we need to separate the datepickers and the monthpickers. We could get one of the few jQuery-UI monthpicker addons out there, but some lack localization flexibility/ability, some lack animation support...so, what to do? Roll your "own" from the datepicker-code! This gets you a fully-functioning monthpicker, with all the functionalities of the datepicker, just without the displaying of days.

I have supplied a monthpicker js-script and the accompanying CSS-script, using the method described below, with the jQuery-UI v1.11.1 code. Simply copy these code-snippets to two new files, monthpicker.js and monthpicker.css, respectively.

If you want to read about the rather simple process by which I converted the datepicker to a monthpicker, scroll down to the last section.

Now to add the datepickers and monthpickers to the page!

These following javascript code-snippets work with multiple datepickers and/or monthpickers on the page, without the aforementioned problems! Fixed generally by using '$(this).' a lot :)

The first script is for a normal datepicker, and the second one is for the "new" monthpickers.

The out-commented .after, which lets you create some element to clear the input-field, is stolen from Paul Richards' answer.

I'm using the "MM yy" format in my monthpicker, and the 'yy-mm-dd' format in my datepicker, but this is completely compatible with all formats, so you are free to use whichever one you want. Simply change the 'dateFormat' option. The standard options 'showButtonPanel', 'showAnim', and 'yearRange' are of course optional and customizable to your wishes.

Adding a datepicker

Datepicker instantiation. This one goes from 90 years ago and to the present day. It helps you to keep the input-field correct, especially if you set the defaultDate, minDate and maxDate options, but it can handle it if you don't. It will work with any dateFormat you choose.

        $('#MyDateTextBox').datepicker({
            dateFormat: 'yy-mm-dd',
            changeMonth: true,
            changeYear: true,
            showButtonPanel: true,
            showMonthAfterYear: true,
            showWeek: true,
            showAnim: "drop",
            constrainInput: true,
            yearRange: "-90:",
            minDate: new Date((new Date().getFullYear() - 90), new Date().getMonth(), new Date().getDate()),
            maxDate: new Date(new Date().getFullYear(), new Date().getMonth(), new Date().getDate()),
            defaultDate: new Date(new Date().getFullYear(), new Date().getMonth(), new Date().getDate()),

            onClose: function (dateText, inst) {
                // When onClose is called after we have clicked a day (and not clicked 'Close' or outside the datepicker), the input-field is automatically
                // updated with a valid date-string. They will always pass, because minDate and maxDate are already enforced by the datepicker UI.
                // This try is to catch and handle the situations, where you open the datepicker, and manually type in an invalid date in the field,
                // and then close the datepicker by clicking outside the datepicker, or click 'Close', in which case no validation takes place.
                try {
                    // If datepicker can parse the date using our formatstring, the instance will automatically parse
                    // and apply it for us (after the onClose is done).
                    // If the input-string is invalid, 'parseDate' will throw an exception, and go to our catch.
                    // If the input-string is EMPTY, then 'parseDate' will NOT throw an exception, but simply return null!
                    var typedDate = $.datepicker.parseDate($(this).datepicker('option', 'dateFormat'), $(this).val());

                    // typedDate will be null if the entered string is empty. Throwing an exception will force the datepicker to
                    // reset to the last set default date.
                    // You may want to just leave the input-field empty, in which case you should replace 'throw "No date selected";' with 'return;'
                    if (typedDate == null)throw "No date selected";

                    // We do a manual check to see if the date is within minDate and maxDate, if they are defined.
                    // If all goes well, the default date is set to the new date, and datepicker will apply the date for us.
                    var minDate = $(this).datepicker("option", "minDate");
                    var maxDate = $(this).datepicker("option", "maxDate");

                // so we do some checks to see if it needs updating. This may not catch ALL cases, but these are

    ;

Adding a monthpicker

Include the monthpicker.js file and the monthpicker.css file in the page you want to use the monthpickers.

Monthpicker instantiation The value retrieved from this monthpicker, is always the FIRST day of the selected month. Starts at the current month, and ranges from 100 years ago and 10 years into the future.

    $('#MyMonthTextBox').monthpicker({
        dateFormat: 'MM yy',
        changeMonth: true,
        changeYear: true,
        showMonthAfterYear: true,
        showAnim: "drop",
        constrainInput: true,
        yearRange: "-100Y:+10Y",
        minDate: new Date(new Date().getFullYear() - 100, new Date().getMonth(), 1),
        maxDate: new Date((new Date().getFullYear() + 10), new Date().getMonth(), 1),
        defaultDate: new Date(new Date().getFullYear(), new Date().getMonth(), 1),

        // Monthpicker functions
        onClose: function (dateText, inst) {
            var date = new Date(inst.selectedYear, inst.selectedMonth, 1);
            $(this).monthpicker('option', 'defaultDate', date);
            $(this).monthpicker('setDate', date);
        },

        beforeShow: function (input, inst) {
            if ($(this).monthpicker("getDate") !== null) {
                // Making sure that the date set is the first of the month.
                if($(this).monthpicker("getDate").getDate() !== 1){
                    var date = new Date(inst.selectedYear, inst.selectedMonth, 1);
                    $(this).monthpicker('option', 'defaultDate', date);
                    $(this).monthpicker('setDate', date);
                }
            } else {
                // If the date is null, we reset it to the defaultDate. Make sure that the defaultDate is always set to the first of the month!
                $(this).monthpicker('setDate', $(this).monthpicker('option', 'defaultDate'));
            }
        },
        // Special monthpicker function!
        onChangeMonthYear: function (year, month, inst) {
            $(this).val($.monthpicker.formatDate($(this).monthpicker('option', 'dateFormat'), new Date(year, month - 1, 1)));
        }
    })
    //.after( // this makes a link labeled "clear" appear to the right of the input-field, which clears the text in it
    //    $("<a href='javascript: void(0);'>clear</a>").click(function() {
    //        $(this).prev().val('');
    //    })
    //)
    ;

That's it! That's all you need to make a monthpicker.

I can't seem to make a jsfiddle work with this, but it is working for me in my ASP.NET MVC project. Just do what you normally do to add a datepicker to your page, and incorporate the above scripts, possibly by changing the selector (meaning $("#MyMonthTextBox")) to something that works for you.

I hope this helps someone.

Links to pastebins for some extra date- and monthpicker setups:

1. Monthpicker working on the last day of the month. The date you get from this monthpicker will always be the last day of the month.

2. Two collaborating monthpickers; 'start' is working on the first of the month, and 'end' is working on the last of the month. They are both restricted by each other, so choosing a month on 'end' which is before the selected month on 'start', will change 'start' to be the same month as 'end'. And vice versa. OPTIONAL: When selecting a month on 'start', the 'minDate' on 'end' is set to that month. To remove this feature, comment out one line in onClose (read the comments).

How I changed the DatePicker into being a MonthPicker

I've taken all the javascript code from jquery-ui-1.11.1.js pertaining to their datepicker, pasted it into a new js-file, and replaced the following strings:

• "datepicker" ==> "monthpicker"
• "Datepicker" ==> "Monthpicker"
• "date picker" ==> "month picker"
• "Date picker" ==> "Month picker"

Then I removed the part of the for-loop which creates the entire ui-datepicker-calendar div (the div which other solutions hide using CSS). This can be found in the _generateHTML: function (inst).

Find the line that says:

"</div><table class='ui-datepicker-calendar'><thead>" +

Mark everything from after the closing div-tag and down to (and not including) the line where it says:

drawMonth++;

Now it'll be unhappy because we need to close some things. After that closing div-tag from before, add this:

";

The code should now be seamed together nicely. Here's a code-snippet showing what you should've ended up with:

...other code...

calender += "<div class='ui-monthpicker-header ui-widget-header ui-helper-clearfix" + cornerClass + "'>" +
                (/all|left/.test(cornerClass) && row === 0 ? (isRTL ? next : prev) : "") +
                (/all|right/.test(cornerClass) && row === 0 ? (isRTL ? prev : next) : "") +
                this._generateMonthYearHeader(inst, drawMonth, drawYear, minDate, maxDate,
                    row > 0 || col > 0, monthNames, monthNamesShort) + // draw month headers
                "</div>";
            drawMonth++;
            if (drawMonth > 11) {
                drawMonth = 0;
                drawYear++;
            }

...other code...

Then I copy/pasted the code from jquery-ui.css pertaining to the datepickers to a new CSS-file, and replaced the following strings:

• "datepicker" ==> "monthpicker"

if you have an array like this:

(users is the name of the array)

Array=>
 [0] => (array)
   'user' => 'john'
   'age' => '23'
 [1] => (array)
  'user' => 'jane'
  'age' => '20'
 [2]=> (array)
  'user' => 'john'
  'age' => '23'

and you want to delete duplicates...then:

$serialized = array();
for ($i=0; $i < sizeof($users); $i++) { 
  $test = in_array($users['user'], $serialized);
    if ($test == false) {
      $serialized[] = $users['user'];
    }
 }

can be a solution :P

Make sure that you run spark in local mode when you load data from local(sc.textFile("file:///path to the file/")) or you will get error like this Caused by: java.io.FileNotFoundException: File file:/data/sparkjob/config2.properties does not exist. Becasuse executors which run on different workers will not find this file in it's local path.

add the line to your .bashrc or .profile. The variables set in $HOME/.profile are active for the current user, the ones in /etc/profile are global. The .bashrc is pulled on each bash session start.

The native JSON object includes two key methods.

1. JSON.parse()
2. JSON.stringify() 

1. The JSON.parse() method parses a JSON string - i.e. reconstructing the original JavaScript object

   var jsObject = JSON.parse(jsonString);

2. JSON.stringify() method accepts a JavaScript object and returns its JSON equivalent.

   var jsonString = JSON.stringify(jsObject);

Yes easy.

To easily understand the problem, imagine we wrote this code:

static void Main(string[] args)
{
    string[] test = new string[3];
    test[0]= "hello1";
    test[1]= "hello2";
    test[2]= "hello3";

    for (int i = 0; i <= 3; i++)
    {
        Console.WriteLine(test[i].ToString());
    }
}

Result will be:

hello1
hello2
hello3

Unhandled Exception: System.IndexOutOfRangeException: Index was outside the bounds of the array.

Size of array is 3 (indices 0, 1 and 2), but the for-loop loops 4 times (0, 1, 2 and 3).
So when it tries to access outside the bounds with (3) it throws the exception.

I prefer using awk. If there is only one column, use $0, else replace it with the last column.

One way,

awk '{print $0, "string to append after each line"}' file > new_file

or this,

awk '$0=$0"string to append after each line"' file > new_file

ProxyCommand nc -proxy xxx.com:8080 %h %p

remove -X connect and use -proxy instead.

Worked for me.

As @Eiríkr Útlendi noted, the accepted solution only considers two white space characters: the horizontal tab (U+0009), and a breaking space (U+0020). It does not consider other whitespace characters such as non-breaking spaces (which happen to be in the text I am trying to deal with). A more complete whitespace character listing is included on Wikipedia and also referenced in the linked Perl answer. A simple C# solution that accounts for these other characters can be built using character class subtraction

[\s-[\r\n]]

or, including Eiríkr Útlendi's solution, you get

[\s\u3000-[\r\n]]

I know this question is old but in case if anyone will look for it in the future. It is possible to have two captcha's on one page. Pink to documentation is here: https://developers.google.com/recaptcha/docs/display Example below is just a copy form doc and you dont have to specify different layouts.

<script type="text/javascript">
  var verifyCallback = function(response) {
    alert(response);
  };
  var widgetId1;
  var widgetId2;
  var onloadCallback = function() {
    // Renders the HTML element with id 'example1' as a reCAPTCHA widget.
    // The id of the reCAPTCHA widget is assigned to 'widgetId1'.
    widgetId1 = grecaptcha.render('example1', {
      'sitekey' : 'your_site_key',
      'theme' : 'light'
    });
    widgetId2 = grecaptcha.render(document.getElementById('example2'), {
      'sitekey' : 'your_site_key'
    });
    grecaptcha.render('example3', {
      'sitekey' : 'your_site_key',
      'callback' : verifyCallback,
      'theme' : 'dark'
    });
  };

Though this one is obvious, and even mentioned in a way put up by Tom who asked this question. But lets put up again.

NVL can have only 2 arguments. Coalesce may have more than 2.

select nvl('','',1) from dual; //Result: ORA-00909: invalid number of arguments
select coalesce('','','1') from dual; //Output: returns 1

you can set it in .bashrc

PATH=$PATH:/opt/ActiveTcl-8.5/bin;export PATH;

Rather than placing an extra scanner.nextLine() each time you want to read something, since it seems you want to accept each input on a new line, you might want to instead changing the delimiter to actually match only newlines (instead of any whitespace, as is the default)

import java.util.Scanner;

class ScannerTest {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        scanner.useDelimiter("\\n");

        System.out.print("Enter an index: ");
        int index = scanner.nextInt();

        System.out.print("Enter a sentence: ");
        String sentence = scanner.next();

        System.out.println("\nYour sentence: " + sentence);
        System.out.println("Your index: " + index);
    }
}

Thus, to read a line of input, you only need scanner.next() that has the same behavior delimiter-wise of next{Int, Double, ...}

The difference with the "nextLine() every time" approach, is that the latter will accept, as an index also <space>3, 3<space> and 3<space>whatever while the former only accepts 3 on a line on its own

Typically you model the enum itself as a class with the enum stereotype

this code will help you to open generated pdf in new tab with required title

In Ultra Edit and Crimson (or Emerald) Editor you can enable/disable the column mode with Alt + C

It would seem that a subclass does inherit the private fields in that these very fields are utilized in the inner workings of the subclass (philosophically speaking). A subclass, in its constructor, calls the superclass constructor. The superclass private fields are obviously inherited by the subclass calling the superclass constructor if the superclass constructor has initialized these fields in its constructor. That's just an example. But of course without accessor methods the subclass cannot access the superclass private fields (it's like not being able to pop the back panel of an iPhone to take the battery out to reset the phone... but the battery is still there).

PS One of the many definitions of inheritance that I have come across: "Inheritance -- a programming technique that allows a derived class to extend the functionality of a base class, inheriting all of its STATE (emphasis is mine) and behaviour."

The private fields, even if not accessible by the subclass, are the inherited state of the superclass.

You can do this :

    df <- data.frame("a" = c(1,2,3,4), "b" = c(4,3,2,1), "x_ind" = c(1,0,1,1), "y_ind" = c(0,0,1,1), "z_ind" = c(0,1,1,1) )
df %>% mutate( bi  = ifelse((df$x_ind + df$y_ind +df$z_ind)== 3, 1,0 ))

If you want to return a boolean value, then you can use something like this (much faster than filter):

players.stream().anyMatch(player -> player.getName().contains(name));

Please make sure your $row[1] , $row[2] contains correct value, we do assume here that 1 = Name , and 2 here is your Address field ?

Assuming you have correctly fetched your records from your Records.php, You can do something like this:

$(document).ready(function()
{
    $('#getRecords').click(function()
    {
        var response = '';
        $.ajax({ type: 'POST',   
                 url: "Records.php",   
                 async: false,
                 success : function(text){
                               $('#table1').html(text);
                           }
           });
    });

}

In your HTML

<table id="table1"> 
    //Let jQuery AJAX Change This Text  
</table>
<button id='getRecords'>Get Records</button>

A little note:

Try learing PDO http://php.net/manual/en/class.pdo.php since mysql_* functions are no longer encouraged..

Here is an overview of the many ways that can be done, for my own reference as well as yours :) The functions return a hash of attribute names and their values.

Vanilla JS:

function getAttributes ( node ) {
    var i,
        attributeNodes = node.attributes,
        length = attributeNodes.length,
        attrs = {};

    for ( i = 0; i < length; i++ ) attrs[attributeNodes[i].name] = attributeNodes[i].value;
    return attrs;
}

Vanilla JS with Array.reduce

Works for browsers supporting ES 5.1 (2011). Requires IE9+, does not work in IE8.

function getAttributes ( node ) {
    var attributeNodeArray = Array.prototype.slice.call( node.attributes );

    return attributeNodeArray.reduce( function ( attrs, attribute ) {
        attrs[attribute.name] = attribute.value;
        return attrs;
    }, {} );
}

jQuery

This function expects a jQuery object, not a DOM element.

function getAttributes ( $node ) {
    var attrs = {};
    $.each( $node[0].attributes, function ( index, attribute ) {
        attrs[attribute.name] = attribute.value;
    } );

    return attrs;
}

Underscore

Also works for lodash.

function getAttributes ( node ) {
    return _.reduce( node.attributes, function ( attrs, attribute ) {
        attrs[attribute.name] = attribute.value;
        return attrs;
    }, {} );
}

lodash

Is even more concise than the Underscore version, but only works for lodash, not for Underscore. Requires IE9+, is buggy in IE8. Kudos to @AlJey for that one.

function getAttributes ( node ) {
    return _.transform( node.attributes, function ( attrs, attribute ) {
        attrs[attribute.name] = attribute.value;
    }, {} );
}

Test page

At JS Bin, there is a live test page covering all these functions. The test includes boolean attributes (hidden) and enumerated attributes (contenteditable="").

create table test_table( 
id integer not null auto_increment primary key, 
stamp_created timestamp default '0000-00-00 00:00:00', 
stamp_updated timestamp default now() on update now() 
);

You don't mention what environment you're running in, which makes a big difference because there isn't a pure Python web browser that's capable of rendering HTML.

But if you're using a Mac, I've used webkit2png with great success. If not, as others have pointed out there are plenty of options.

You have to close that application first. There is no way to delete it, if it's used by some application.

UnLock IT is a neat utility that helps you to take control of any file or folder when it is locked by some application or system. For every locked resource, you get a list of locking processes and can unlock it by terminating those processes. EMCO Unlock IT offers Windows Explorer integration that allows unlocking files and folders by one click in the context menu.

There's also Unlocker (not recommended, see Warning below), which is a free tool which helps locate any file locking handles running, and give you the option to turn it off. Then you can go ahead and do anything you want with those files.

Warning: The installer includes a lot of undesirable stuff. You're almost certainly better off with UnLock IT.

Use this function:

function is_checkbox(selector) {
    var $result = $(selector);
    return $result[0] && $result[0].type === 'checkbox';
};

Or this jquery plugin:

$.fn.is_checkbox = function () { return this.is(':checkbox'); };

Agree to dr evil if you use HTTPListener you will have many problems, you have to parse requests and will be engaged to headers and ...

1. Use tcp listener to listen to browser requests
   
2. parse only the first line of the request and get the host domain and port to connect
3. send the exact raw request to the found host on the first line of browser request
4. receive the data from the target site(I have problem in this section)
5. send the exact data received from the host to the browser

you see you dont need to even know what is in the browser request and parse it, only get the target site address from the first line first line usually likes this GET http://google.com HTTP1.1 or CONNECT facebook.com:443 (this is for ssl requests)

Now python gives you the choice to install pip during the installation (I am on Windows, and at least python does so for Windows!). Considering you had chosen to install pip during installation of python (you don't actually have to choose because it is default), pip is already installed for you. Then, type in pip in command prompt, you should see a help come up. You can find necessary usage instructions there. E.g. pip list shows you the list of installed packages. You can use

pip uninstall package_name

to uninstall any package that you don't want anymore. Read more here (pip documentation).

go to Start->Run type inetmgr and press OK. If you get an IIS configuration screen. It is installed, otherwise it isn't.

You can also check ControlPanel->Add Remove Programs, Click Add Remove Windows Components and look for IIS in the list of installed components.

EDIT

To Reinstall IIS.

Control Panel -> Add Remove Programs -> Click Add Remove Windows Components
Uncheck IIS box

Click next and follow prompts to UnInstall IIS. Insert your windows disc into the appropriate drive.

Control Panel -> Add Remove Programs -> Click Add Remove Windows Components
Check IIS box

Click next and follow prompts to Install IIS.

Here's a less flexible alternative using unset():

$array = array(
    1 => 'one',
    2 => 'two',
    3 => 'three'
);
$disallowed = array(1,3);
foreach($disallowed as $key){
    unset($array[$key]);
}

The result of print_r($array) being:

Array
(
    [2] => two
)

This is not applicable if you want to keep the filtered values for later use but tidier, if you're certain that you don't.

Time changes everything. I was looking to do the same recently and came up with this:

As indicated by shadowbq, the DirectoryId and TenantId both equate to the GUID representing the ActiveDirectory Tenant. Depending on context, either term may be used by Microsoft documentation and products, which can be confusing.

Assumptions

• You have access to the Azure Portal

Solution

The tenant ID is tied to ActiveDirectoy in Azure

• Navigate to Dashboard
• Navigate to ActiveDirectory
• Navigate to Manage / Properties
• Copy the "Directory ID"

Yes I used paint, don't judge me.

Use SimpleDateFormat#format:

DateFormat originalFormat = new SimpleDateFormat("MMMM dd, yyyy", Locale.ENGLISH);
DateFormat targetFormat = new SimpleDateFormat("yyyyMMdd");
Date date = originalFormat.parse("August 21, 2012");
String formattedDate = targetFormat.format(date);  // 20120821

Also note that parse takes a String, not a Date object, which is already parsed.

This is Pythons way do show you unicode encoded strings. But i think you should be able to print the string on the screen or write it into a new file without any problems.

>>> test = u"I don\u2018t like this"

Think of an object like a Speaker. If Speaker is a class, It will have different variables such as volume, treble, bass, color etc. You define all these fields while defining the Speaker class. For example, you declared the color field with a static modifier, that means you're telling the compiler that there is exactly one copy of this variable in existence, regardless of how many times the class has been instantiated.

Declaring

static final String color = "Black"; 

will make sure that whenever this class is instantiated, the value of color field will be "Black" unless it is not changed.

public class Speaker {

static String color = "Black";

}

public class Sample {

public static void main(String args[]) {
    System.out.println(Speaker.color); //will provide output as "Black"
            Speaker.color = "white";
    System.out.println(Speaker.color);  //will provide output as "White"
}}

Note : Now once you change the color of the speaker as final this code wont execute, because final keyword makes sure that the value of the field never changes.

public class Speaker {

static final String color = "Black";

}

public class Sample {

public static void main(String args[]) {
    System.out.println(Speaker.color); //should provide output as "Black"
            Speaker.color = "white"; //Error because the value of color is fixed.  
    System.out.println(Speaker.color); //Code won't execute.
}}

You may copy/paste this code directly into your emulator and try.

Custom domain SSL certs were just added today for $600/cert/month. Sign up for your invite below: http://aws.amazon.com/cloudfront/custom-ssl-domains/

Update: SNI customer provided certs are now available for no additional charge. Much cheaper than $600/mo, and with XP nearly killed off, it should work well for most use cases.

@skalee AWS has a mechanism for achieving what the poster asks for, "implement SSL for an Amazon s3 bucket", it's called CloudFront. I'm reading "implement" as "use my SSL certs," not "just put an S on the HTTP URL which I'm sure the OP could have surmised.

Since CloudFront costs exactly the same as S3 ($0.12/GB), but has a ton of additional features around SSL AND allows you to add your own SNI cert at no additional cost, it's the obvious fix for "implementing SSL" on your domain.

I've experienced "internal errors" in the .NET runtime that turned out to be caused by bugs in my code; don't think that just because it was an "internal error" in the .NET runtime that there isn't a bug in your code as the root cause. Always always always blame your own code before you blame someone else's.

Hopefully you have logging and exception/stack trace information to point you where to start looking, or that you can repeat the state of the system before the crash.

VB6/VBA uses deterministic approach to destoying objects. Each object stores number of references to itself. When the number reaches zero, the object is destroyed.

Object variables are guaranteed to be cleaned (set to Nothing) when they go out of scope, this decrements the reference counters in their respective objects. No manual action required.

There are only two cases when you want an explicit cleanup:

1. When you want an object to be destroyed before its variable goes out of scope (e.g., your procedure is going to take long time to execute, and the object holds a resource, so you want to destroy the object as soon as possible to release the resource).

2. When you have a circular reference between two or more objects.

   If objectA stores a references to objectB, and objectB stores a reference to objectA, the two objects will never get destroyed unless you brake the chain by explicitly setting objectA.ReferenceToB = Nothing or objectB.ReferenceToA = Nothing.

The code snippet you show is wrong. No manual cleanup is required. It is even harmful to do a manual cleanup, as it gives you a false sense of more correct code.

If you have a variable at a class level, it will be cleaned/destroyed when the class instance is destructed. You can destroy it earlier if you want (see item 1.).

If you have a variable at a module level, it will be cleaned/destroyed when your program exits (or, in case of VBA, when the VBA project is reset). You can destroy it earlier if you want (see item 1.).

Access level of a variable (public vs. private) does not affect its life time.

You can use:

adb shell monkey -p com.package.name -c android.intent.category.LAUNCHER 1

This will start the LAUNCHER Activity of the application using monkeyrunner test tool.

The only time I've ever used this in practice is with numpy/pandas. For example, with the .isin() dataframe method.

In the docs they show this basic example

>>> df.isin([0, 2])
        num_legs  num_wings
falcon      True       True
dog        False       True

But what if instead you wanted all the rows not in [0, 2]?

>>> ~df.isin([0, 2])
        num_legs  num_wings
falcon     False       False
dog        True        False

To view database roles assigned to users, you can use sys.database_role_members

The following query returns the members of the database roles.

SELECT DP1.name AS DatabaseRoleName,   
    isnull (DP2.name, 'No members') AS DatabaseUserName   
FROM sys.database_role_members AS DRM  
RIGHT OUTER JOIN sys.database_principals AS DP1  
    ON DRM.role_principal_id = DP1.principal_id  
LEFT OUTER JOIN sys.database_principals AS DP2  
    ON DRM.member_principal_id = DP2.principal_id  
WHERE DP1.type = 'R'
ORDER BY DP1.name;  

this work for me, just prevent the event, add the url to an <a> tag then trigger the click event on that tag.

Js
$('.myBtn').on('click', function(event) {
        event.preventDefault();
        $(this).attr('href',"http://someurl.com");
        $(this).trigger('click');
});
HTML
<a href="#" class="myBtn" target="_blank">Go</a>

Markus has one way to avoid using the word for -- here's another, which should have much better performance for long the_lists...:

import itertools
found = any(itertools.ifilter(lambda x:x[1]=='b', the_list)

I had same error and the mistake was that I had added list and dictionary into the same list (object) and when I used to iterate over the list of dictionaries and use to hit a list (type) object then I used to get this error.

Its was a code error and made sure that I only added dictionary objects to that list and list typed object into the list, this solved my issue as well.

In your statement, you are comparing a string called start_date with the time.
If start_date is a column, it should either be

 
  SELECT * FROM `la_schedule` WHERE start_date >'2012-11-18';
 

(no apostrophe) or

SELECT * FROM `la_schedule` WHERE `start_date` >'2012-11-18';

(with backticks).

Hope this helps.

The only way that cleanly solved this issue for me (.NET 4.6.1) was to not only add a Nuget reference to System.Net.Http V4.3.4 for the project that actually used System.Net.Http, but also to the startup project (a test project in my case).

(Which is strange, because the correct System.Net.Http.dll existed in the bin directory of the test project and the .config assemblyBingings looked OK, too.)

You need to do this:

    exec procName 
    @parameter_1_Name = 'parameter_1_Value', 
    @parameter_2_name = 'parameter_2_value',
    @parameter_z_name = 'parameter_z_value'

If you prefer attr_accessible, you could use it in Rails 4 too. You should install it like gem:

gem 'protected_attributes'

after that you could use attr_accessible in you models like in Rails 3

Also, and i think that is the best way- using form objects for dealing with mass assignment, and saving nested objects, and you can also use protected_attributes gem that way

class NestedForm
   include  ActiveModel::MassAssignmentSecurity
   attr_accessible :name,
                   :telephone, as: :create_params
   def create_objects(params)
      SomeModel.new(sanitized_params(params, :create_params))
   end
end

My solution introduces a static function for the global Object object.

(function() {
    var lastStorageId = 0;

    this.Object.hash = function(object) {
        var hash = object.__id;

        if (!hash)
             hash = object.__id = lastStorageId++;

        return '#' + hash;
    };
}());

I think this is more convenient with other object manipulating functions in JavaScript.

As mentioned earlier.

 sudo rm -rf /usr/local/lib/node_modules/npm
 brew uninstall --force node                
 brew install node

Someone has published a docker container / file for this:

https://github.com/vipul-sharma20/docker-opencv3-python3

https://hub.docker.com/r/vipul20/docker-opencv3-python3/~/dockerfile/

You can pull the image directly from docker hub or follow the instructions in the Dockerfile to install.

I'm using this one:

  internal static bool IsValidJson(string data)
  {
     data = data.Trim();
     try
     {
        if (data.StartsWith("{") && data.EndsWith("}"))
        {
           JToken.Parse(data);
        }
        else if (data.StartsWith("[") && data.EndsWith("]"))
        {
           JArray.Parse(data);
        }
        else
        {
           return false;
        }
        return true;
     }
     catch
     {
        return false;
     }

You need to set a height on the DIV. Otherwise it will keep expanding indefinitely.

The class java.sql.Date is designed to carry only a date without time, so the conversion result you see is correct for this type. You need to use a java.sql.Timestamp to get a full date with time.

java.util.Date newDate = result.getTimestamp("VALUEDATE");

It's extremely unlikely that an if/else or a switch is going to be the source of your performance woes. If you're having performance problems, you should do a performance profiling analysis first to determine where the slow spots are. Premature optimization is the root of all evil!

Nevertheless, it's possible to talk about the relative performance of switch vs. if/else with the Java compiler optimizations. First note that in Java, switch statements operate on a very limited domain -- integers. In general, you can view a switch statement as follows:

switch (<condition>) {
   case c_0: ...
   case c_1: ...
   ...
   case c_n: ...
   default: ...
}

where c_0, c_1, ..., and c_N are integral numbers that are targets of the switch statement, and <condition> must resolve to an integer expression.

• If this set is "dense" -- that is, (max(c_i) + 1 - min(c_i)) / n > α, where 0 < k < α < 1, where k is larger than some empirical value, a jump table can be generated, which is highly efficient.

• If this set is not very dense, but n >= β, a binary search tree can find the target in O(2 * log(n)) which is still efficient too.

For all other cases, a switch statement is exactly as efficient as the equivalent series of if/else statements. The precise values of α and β depend on a number of factors and are determined by the compiler's code-optimization module.

Finally, of course, if the domain of <condition> is not the integers, a switch statement is completely useless.

In Chrome 35 update, download attribute behavior was changed.

https://code.google.com/p/chromium/issues/detail?id=373182

to work this in chrome, use this

var pom = document.createElement('a');
var csvContent=csv; //here we load our csv data 
var blob = new Blob([csvContent],{type: 'text/csv;charset=utf-8;'});
var url = URL.createObjectURL(blob);
pom.href = url;
pom.setAttribute('download', 'foo.csv');
pom.click();

Nope, there is not. You'll have to use the primitive long data type and deal with signedness issues, or use a class such as BigInteger.

One major difference is the support of "Indic Fonts" aka South Asian Scripts (including Southeast Asian languages such as Khmer, Lao, Myanmar and Thai). Also, there is much better support for East Asian languages (Chinese, Japanese, Korean). These are known bugs (actually the most highly rated bugs) that have been going on for years (thought it appears East Asian language support used to work better but have now become difficult to use):

Simply add this

$id = ''; 
if( isset( $_GET['id'])) {
    $id = $_GET['id']; 
} 

If none of your routes contain closures, but you are still getting this error, please check

routes/api.php

Laravel has a default auth api route in the above file.

Route::middleware('auth:api')->get('/user', function (Request $request) {
    return $request->user();
});

which can be commented or replaced with a call to controller method if required.

I had the same problem on printing a PDF file. There's a nuget package called Spire.Pdf that's very simple to use. The free version has a limit of 10 pages although, however, in my case it was the best solution once I don't want to depend on Adobe Reader and I don't want to install any other components.

https://www.nuget.org/packages/Spire.PDF/

PdfDocument pdfdocument = new PdfDocument();
pdfdocument.LoadFromFile(pdfPathAndFileName);
pdfdocument.PrinterName = "My Printer";
pdfdocument.PrintDocument.PrinterSettings.Copies = 2;
pdfdocument.PrintDocument.Print();
pdfdocument.Dispose();

Constructor overloading is like method overloading. Constructors can be overloaded to create objects in different ways.

The compiler differentiates constructors based on how many arguments are present in the constructor and other parameters like the order in which the arguments are passed.

If you want to change one specific onclick event with jQuery, you better use the functions .on() and .off() with a namespace (see documentation).

Use .on() to create your event and .off() to remove it. You can also create a global object like g_specific_events_set = {}; to avoid duplicates:

    alert('First alert!');_x000D_

With Windows 8.1 I couldn't find any .exd files using windows search. On the other hand, a cmd command dir *.exd /S found the one file on my system.

I know it's been some time, but there is a more elegant solution. From the mozilla docs:

Math.sign(parseInt(-3))

It will give you -1 for negative, 0 for zero and 1 for positive.

I'm developing a scientific calculator that sports an Int button. I've found the following is a simple, reliable solution:

double dblInteger;
if( dblNumber < 0 )
   dblInteger = Math.Ceiling(dblNumber);
else
   dblInteger = Math.Floor(dblNumber);

Math.Round sometimes produces unexpected or undesirable results, and explicit conversion to integer (via cast or Convert.ToInt...) often produces wrong values for higher-precision numbers. The above method seems to always work.

$("form:first").submit();

See events/submit.

    public async Task<ActionResult> Index()
    {
        apiTable table = new apiTable();
        table.Name = "Asma Nadeem";
        table.Roll = "6655";

        string str = "";
        string str2 = "";

        HttpClient client = new HttpClient();

        string json = JsonConvert.SerializeObject(table);

        StringContent httpContent = new StringContent(json, System.Text.Encoding.UTF8, "application/json");

        var response = await client.PostAsync("http://YourSite.com/api/apiTables", httpContent);

        str = "" + response.Content + " : " + response.StatusCode;

        if (response.IsSuccessStatusCode)
        {       
            str2 = "Data Posted";
        }

        return View();
    }

To prevent the page from jumping, you need to call e.stopPropagation(); after calling e.preventDefault();:

stopPropagation prevents the event from going up the DOM tree. More info here: https://api.jquery.com/event.stoppropagation/

I'd agree inheritance is a better fit for the problem posed.

I found this question really handy though on decorating classes, thanks all.

Here's another couple of examples, based on other answers, including how inheritance affects things in Python 2.7, (and @wraps, which maintains the original function's docstring, etc.):

def dec(klass):
    old_foo = klass.foo
    @wraps(klass.foo)
    def decorated_foo(self, *args ,**kwargs):
        print('@decorator pre %s' % msg)
        old_foo(self, *args, **kwargs)
        print('@decorator post %s' % msg)
    klass.foo = decorated_foo
    return klass

@dec  # No parentheses
class Foo...

Often you want to add parameters to your decorator:

from functools import wraps

def dec(msg='default'):
    def decorator(klass):
        old_foo = klass.foo
        @wraps(klass.foo)
        def decorated_foo(self, *args ,**kwargs):
            print('@decorator pre %s' % msg)
            old_foo(self, *args, **kwargs)
            print('@decorator post %s' % msg)
        klass.foo = decorated_foo
        return klass
    return decorator

@dec('foo decorator')  # You must add parentheses now, even if they're empty
class Foo(object):
    def foo(self, *args, **kwargs):
        print('foo.foo()')

@dec('subfoo decorator')
class SubFoo(Foo):
    def foo(self, *args, **kwargs):
        print('subfoo.foo() pre')
        super(SubFoo, self).foo(*args, **kwargs)
        print('subfoo.foo() post')

@dec('subsubfoo decorator')
class SubSubFoo(SubFoo):
    def foo(self, *args, **kwargs):
        print('subsubfoo.foo() pre')
        super(SubSubFoo, self).foo(*args, **kwargs)
        print('subsubfoo.foo() post')

SubSubFoo().foo()

Outputs:

@decorator pre subsubfoo decorator
subsubfoo.foo() pre
@decorator pre subfoo decorator
subfoo.foo() pre
@decorator pre foo decorator
foo.foo()
@decorator post foo decorator
subfoo.foo() post
@decorator post subfoo decorator
subsubfoo.foo() post
@decorator post subsubfoo decorator

I've used a function decorator, as I find them more concise. Here's a class to decorate a class:

class Dec(object):

    def __init__(self, msg):
        self.msg = msg

    def __call__(self, klass):
        old_foo = klass.foo
        msg = self.msg
        def decorated_foo(self, *args, **kwargs):
            print('@decorator pre %s' % msg)
            old_foo(self, *args, **kwargs)
            print('@decorator post %s' % msg)
        klass.foo = decorated_foo
        return klass

A more robust version that checks for those parentheses, and works if the methods don't exist on the decorated class:

from inspect import isclass

def decorate_if(condition, decorator):
    return decorator if condition else lambda x: x

def dec(msg):
    # Only use if your decorator's first parameter is never a class
    assert not isclass(msg)

    def decorator(klass):
        old_foo = getattr(klass, 'foo', None)

        @decorate_if(old_foo, wraps(klass.foo))
        def decorated_foo(self, *args ,**kwargs):
            print('@decorator pre %s' % msg)
            if callable(old_foo):
                old_foo(self, *args, **kwargs)
            print('@decorator post %s' % msg)

        klass.foo = decorated_foo
        return klass

    return decorator

The assert checks that the decorator has not been used without parentheses. If it has, then the class being decorated is passed to the msg parameter of the decorator, which raises an AssertionError.

@decorate_if only applies the decorator if condition evaluates to True.

The getattr, callable test, and @decorate_if are used so that the decorator doesn't break if the foo() method doesn't exist on the class being decorated.

As mentioned you can use:

overflow: scroll;

If you only want the scroll bar to appear when necessary, you can use the "auto" option:

overflow: auto;

I don't think you should be using the "float" property with "overflow", but I'd have to try out your example first.

Strictly stated you must check all of the following: defined, not empty AND not None.

For "normal" variables it makes a difference if defined and set or not set. See foo and bar in the example below. Both are defined but only foo is set.

On the other side registered variables are set to the result of the running command and vary from module to module. They are mostly json structures. You probably must check the subelement you're interested in. See xyz and xyz.msg in the example below:

cat > test.yml <<EOF
- hosts: 127.0.0.1

  vars:
    foo: ""          # foo is defined and foo == '' and foo != None
    bar:             # bar is defined and bar != '' and bar == None

  tasks:

  - debug:
      msg : ""
    register: xyz    # xyz is defined and xyz != '' and xyz != None
                     # xyz.msg is defined and xyz.msg == '' and xyz.msg != None

  - debug:
      msg: "foo is defined and foo == '' and foo != None"
    when: foo is defined and foo == '' and foo != None

  - debug:
      msg: "bar is defined and bar != '' and bar == None"
    when: bar is defined and bar != '' and bar == None

  - debug:
      msg: "xyz is defined and xyz != '' and xyz != None"
    when: xyz is defined and xyz != '' and xyz != None
  - debug:
      msg: "{{ xyz }}"

  - debug:
      msg: "xyz.msg is defined and xyz.msg == '' and xyz.msg != None"
    when: xyz.msg is defined and xyz.msg == '' and xyz.msg != None
  - debug:
      msg: "{{ xyz.msg }}"

1.Hashmap and HashTable both store key and value.

2.Hashmap can store one key as null. Hashtable can't store null.

3.HashMap is not synchronized but Hashtable is synchronized.

4.HashMap can be synchronized with Collection.SyncronizedMap(map)

Map hashmap = new HashMap();

Map map = Collections.SyncronizedMap(hashmap);

This is a good approach to show animation in and out using jQuery

  $(document).ready(function() {
      // show the alert
      $(".alert").first().hide().slideDown(500).delay(4000).slideUp(500, function () {
         $(this).remove(); 
      });
  });

You can easily use .replace() as also previously described. But it is also important to keep in mind that strings are immutable. Hence if you do not assign the change you are making to a variable, then you will not see any change. Let me explain by;

    >>stuff = "bin and small"
    >>stuff.replace('and', ',')
    >>print(stuff)
    "big and small" #no change

To observe the change you want to apply, you can assign same or another variable;

    >>stuff = "big and small"
    >>stuff = stuff.replace("and", ",")   
    >>print(stuff)
    'big, small'

Simple way i found out was to make a new xml file in the drawable folder and then point the buttons background to that xml file. heres the code i used:

<solid android:color="#ff8100"/>
<corners android:radius="5dp"/>

If you want some flexibility, create a class that watches the size of the list.

Here's a simple example. You would need to override all the methods that change the state of the list.

public class LimitedArrayList<T> extends ArrayList<T>{
    private int limit;

    public LimitedArrayList(int limit){
        this.limit = limit;
    }

    @Override
    public void add(T item){
        if (this.size() > limit)
            throw new ListTooLargeException();
        super.add(item);
    }

    // ... similarly for other methods that may add new elements ...

Intro:

By default, Windows Communication Foundation (WCF) makes endpoints available only to SOAP clients. In How to: Create a Basic WCF Web HTTP Service, an endpoint is made available to non-SOAP clients. There may be times when you want to make the same contract available both ways, as a Web endpoint and as a SOAP endpoint. This topic shows an example of how to do this.

You can probably use the KeyDown event, KeyPress event or KeyUp event. I would first try the KeyDown event I think.

You can set the Handled property of the event args to stop handling the event.

I'm hitting Microsoft SQL Server 2008 R2 from a single-threaded JDBC-based application and pulling back the last ID without using the RETURN_GENERATED_KEYS property or any PreparedStatement. Looks something like this:

private int insertQueryReturnInt(String SQLQy) {
    ResultSet generatedKeys = null;
    int generatedKey = -1;

    try {
        Statement statement = conn.createStatement();
        statement.execute(SQLQy);
    } catch (Exception e) {
        errorDescription = "Failed to insert SQL query: " + SQLQy + "( " + e.toString() + ")";
        return -1;
    }

    try {
        generatedKey = Integer.parseInt(readOneValue("SELECT @@IDENTITY"));
    } catch (Exception e) {
        errorDescription = "Failed to get ID of just-inserted SQL query: " + SQLQy + "( " + e.toString() + ")";
        return -1;
    }

    return generatedKey;
} 

This blog post nicely isolates three main SQL Server "last ID" options: http://msjawahar.wordpress.com/2008/01/25/how-to-find-the-last-identity-value-inserted-in-the-sql-server/ - haven't needed the other two yet.

SELECT
   CASE 
   WHEN xyz.something = 1 THEN 'SOMETEXT'
   WHEN xyz.somethingelse = 1 THEN 'SOMEOTHERTEXT'
   WHEN xyz.somethingelseagain = 2 THEN 'SOMEOTHERTEXTGOESHERE'
   ELSE 'SOMETHING UNKNOWN'
   END AS ColumnName;

First, don't use update panels. They are the second most evil thing that Microsoft has ever created for the web developer.

Second, if you must use update panels, try setting the UpdateMode property to Conditional. Then add a trigger to an Asp:Hidden control that you add to the page. Assign the change event as the trigger. In your dragstop event, change the value of the hidden control.

This is untested, but the theory seems sound... If this does not work, you could try the same thing with an asp:button, just set the display:none style on it and use the click event instead of the change event.

In Java there is a difference between x++ and ++x

++x is a prefix form: It increments the variables expression then uses the new value in the expression.

For example if used in code:

int x = 3;

int y = ++x;
//Using ++x in the above is a two step operation.
//The first operation is to increment x, so x = 1 + 3 = 4
//The second operation is y = x so y = 4

System.out.println(y); //It will print out '4'
System.out.println(x); //It will print out '4'

x++ is a postfix form: The variables value is first used in the expression and then it is incremented after the operation.

For example if used in code:

int x = 3;

int y = x++;
//Using x++ in the above is a two step operation.
//The first operation is y = x so y = 3
//The second operation is to increment x, so x = 1 + 3 = 4

System.out.println(y); //It will print out '3'
System.out.println(x); //It will print out '4' 

Hope this is clear. Running and playing with the above code should help your understanding.

First, you want to use

model <- lm(Total ~ Coupon, data=df)

not model <-lm(df$Total ~ df$Coupon, data=df).

Second, by saying lm(Total ~ Coupon), you are fitting a model that uses Total as the response variable, with Coupon as the predictor. That is, your model is of the form Total = a + b*Coupon, with a and b the coefficients to be estimated. Note that the response goes on the left side of the ~, and the predictor(s) on the right.

Because of this, when you ask R to give you predicted values for the model, you have to provide a set of new predictor values, ie new values of Coupon, not Total.

Third, judging by your specification of newdata, it looks like you're actually after a model to fit Coupon as a function of Total, not the other way around. To do this:

model <- lm(Coupon ~ Total, data=df)
new.df <- data.frame(Total=c(79037022, 83100656, 104299800))
predict(model, new.df)

You can redirect the output of a command to a file:

$ cat file > copy_file

or append to it

$ cat file >> copy_file

If you want to write directly the command is echo 'text'

$ echo 'Hello World' > file

I rewrote the @Udinic answer so that the code generates table creation query automatically. It also doesn't need ConnectionSource. It also has to do this inside a transaction.
