The parameter has this syntax:

{minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}

So your example of '1.2-2' means:

• A minimum of 1 digit will be shown before decimal point
• It will show at least 2 digits after decimal point
• But not more than 2 digits

First of all, it's not very tidy to mix pylab and pyplot code. What's more, pyplot style is preferred over using pylab.

Here is a slightly cleaned up code, using only pyplot functions:

from matplotlib import pyplot

a = [ pow(10,i) for i in range(10) ]

pyplot.subplot(2,1,1)
pyplot.plot(a, color='blue', lw=2)
pyplot.yscale('log')
pyplot.show()

The relevant function is pyplot.yscale(). If you use the object-oriented version, replace it by the method Axes.set_yscale(). Remember that you can also change the scale of X axis, using pyplot.xscale() (or Axes.set_xscale()).

Check my question What is the difference between ‘log’ and ‘symlog’? to see a few examples of the graph scales that matplotlib offers.

I'm arriving a bit late to the party, but I've got three four five:

1. If you poll InvokeRequired on a control that hasn't been loaded/shown, it will say false - and blow up in your face if you try to change it from another thread (the solution is to reference this.Handle in the creator of the control).

2. Another one which tripped me up is that given an assembly with:

   enum MyEnum
   {
       Red,
       Blue,
   }
   

   if you calculate MyEnum.Red.ToString() in another assembly, and in between times someone has recompiled your enum to:

   enum MyEnum
   {
       Black,
       Red,
       Blue,
   }
   

   at runtime, you will get "Black".

3. I had a shared assembly with some handy constants in. My predecessor had left a load of ugly-looking get-only properties, I thought I'd get rid of the clutter and just use public const. I was more than a little surprised when VS compiled them to their values, and not references.

4. If you implement a new method of an interface from another assembly, but you rebuild referencing the old version of that assembly, you get a TypeLoadException (no implementation of 'NewMethod'), even though you have implemented it (see here).

5. Dictionary<,>: "The order in which the items are returned is undefined". This is horrible, because it can bite you sometimes, but work others, and if you've just blindly assumed that Dictionary is going to play nice ("why shouldn't it? I thought, List does"), you really have to have your nose in it before you finally start to question your assumption.

Something like the following example. Note I'm in Eastern Australia (UTC + 10 hours at the moment).

>>> import datetime
>>> dtnow = datetime.datetime.now();dtutcnow = datetime.datetime.utcnow()
>>> dtnow
datetime.datetime(2010, 8, 4, 9, 33, 9, 890000)
>>> dtutcnow
datetime.datetime(2010, 8, 3, 23, 33, 9, 890000)
>>> delta = dtnow - dtutcnow
>>> delta
datetime.timedelta(0, 36000)
>>> hh,mm = divmod((delta.days * 24*60*60 + delta.seconds + 30) // 60, 60)
>>> hh,mm
(10, 0)
>>> "%s%+02d:%02d" % (dtnow.isoformat(), hh, mm)
'2010-08-04T09:33:09.890000+10:00'
>>>

I would use &emsp; is a lot cleaner in my opinion.

Instead of using success, I change it to then and it works.

here is the code:

lgrg.controller('login', function($scope, $window, $http) {
    $scope.loginUser = {};

    $scope.submitForm = function() {
        $scope.errorInfo = null

        $http({
            method  : 'POST',
            url     : '/login',
            headers : {'Content-Type': 'application/json'}
            data: $scope.loginUser
        }).then(function(data) {
            if (!data.status) {
                $scope.errorInfo = data.info
            } else {
                //page jump
                $window.location.href = '/admin';
            }
        });
    };
});

The fastest way would be using bulk insert extension, which I developed

note: this is a commercial product, not free of charge

It uses SqlBulkCopy and custom datareader to get max performance. As a result it is over 20 times faster than using regular insert or AddRange

usage is extremely simple

context.BulkInsert(hugeAmountOfEntities);

Use this server variable to get the protocol details:

 $scheme = $_SERVER['REQUEST_SCHEME'] . '://';
 echo $scheme; //it gives http:// or https://

Note that this server variable is unreliable. For more information take a look at: Is $_SERVER['REQUEST_SCHEME'] reliable?

Take a look at Job Control on UNIX systems

If you don't have control of your shell, simply hitting ctrl + C should stop the process. If that doesn't work, you can try ctrl + Z and using the jobs and kill -9 %<job #> to kill it. The '-9' is a type of signal. You can man kill to see a list of signals.

Not an answer to the original question, but an example to the how-to-make-reusable and working custom renderers without breaking MVC :-)

// WRONG
public class DataWrapper {
   final Data data;
   final String description;
   public DataWrapper(Object data, String description) {
       this.data = data;
       this.description = description;
   }
   ....
   @Override
   public String toString() {
       return description;
   } 
}
// usage
myModel.add(new DataWrapper(data1, data1.getName());

It is wrong in a MVC environment, because it is mixing data and view: now the model doesn't contain the data but a wrapper which is introduced for view reasons. That's breaking separation of concerns and encapsulation (every class interacting with the model needs to be aware of the wrapped data).

The driving forces for breaking of rules were:

• keep functionality of the default KeySelectionManager (which is broken by a custom renderer)
• reuse of the wrapper class (can be applied to any data type)

As in Swing a custom renderer is the small coin designed to accomodate for custom visual representation, a default manager which can't cope is ... broken. Tweaking design just to accommodate for such a crappy default is the wrong way round, kind of upside-down. The correct is, to implement a coping manager.

While re-use is fine, doing so at the price of breaking the basic architecture is not a good bargin.

We have a problem in the presentation realm, let's solve it in the presentation realm with the elements designed to solve exactly that problem. As you might have guessed, SwingX already has such a solution :-)

In SwingX, the provider of a string representation is called StringValue, and all default renderers take such a StringValue to configure themselves:

StringValue sv = new StringValue() {
     @Override
     public String getString(Object value) {
        if (value instanceof Data) {
            return ((Data) value).getSomeProperty();
        }
        return TO_STRING.getString(value);
     }
};
DefaultListRenderer renderer = new DefaultListRenderer(sv);

As the defaultRenderer is-a StringValue (implemented to delegate to the given), a well-behaved implementation of KeySelectionManager now can delegate to the renderer to find the appropriate item:

public BetterKeySelectionManager implements KeySelectionManager {

     @Override
     public int selectionForKey(char ch, ComboBoxModel model) {

         ....
         if (getCellRenderer() instance of StringValue) {
              String text = ((StringValue) getCellRenderer()).getString(model.getElementAt(row));
              ....
         } 
     }

}

Outlined the approach because it is easily implementable even without using SwingX, simply define implement something similar and use it:

• some provider of a string representation
• a custom renderer which is configurable by that provider and guarantees to use it in configuring itself
• a well-behaved keySelectionManager with queries the renderer for its string represention

All except the string provider is reusable as-is (that is exactly one implemenation of the custom renderer and the keySelectionManager). There can be general implementations of the string provider, f.i. those formatting value or using bean properties via reflection. And all without breaking basic rules :-)

Try to use rbindlist approach over rbind as it's very, very fast.

Example:

library(data.table)

##### example 1: slow processing ######

table.1 <- data.frame(x = NA, y = NA)
time.taken <- 0
for( i in 1:100) {
  start.time = Sys.time()
  x <- rnorm(100)
  y <- x/2 +x/3
  z <- cbind.data.frame(x = x, y = y)

  table.1 <- rbind(table.1, z)
  end.time <- Sys.time()
  time.taken  <- (end.time - start.time) + time.taken

}
print(time.taken)
> Time difference of 0.1637917 secs

####example 2: faster processing #####

table.2 <- list()
t0 <- 0
for( i in 1:100) {
  s0 = Sys.time()
  x <- rnorm(100)
  y <- x/2 + x/3

  z <- cbind.data.frame(x = x, y = y)

  table.2[[i]] <- z

  e0 <- Sys.time()
  t0  <- (e0 - s0) + t0

}
s1 = Sys.time()
table.3 <- rbindlist(table.2)
e1 = Sys.time()

t1  <- (e1-s1) + t0
t1
> Time difference of 0.03064394 secs

Referring to the answers above, I am only adding this to help clarify things. It is possible to use HttpClient from .Net 4.0, and you have to install the package from here

However, the text is very confusion and contradicts itself.

This package is not supported in Visual Studio 2010, and is only required for projects targeting .NET Framework 4.5, Windows 8, or Windows Phone 8.1 when consuming a library that uses this package.

But underneath it states that these are the supported platforms.

Supported Platforms:

• .NET Framework 4

• Windows 8

• Windows Phone 8.1

• Windows Phone Silverlight 7.5

• Silverlight 4

• Portable Class Libraries

Ignore what it ways about targeting .Net 4.5. This is wrong. The package is all about using HttpClient in .Net 4.0. However, you may need to use VS2012 or higher. Not sure if it works in VS2010, but that may be worth testing.

For Email Address validation try this simple and easy code.

    String email = inputEmail.getText().toString().trim();

    if (!Patterns.EMAIL_ADDRESS.matcher(email).matches())
    {
        inputEmail.setError("Enter Valid Email Address");
        inputEmail.requestFocus();
    }

You can just use a simple loop: -

>>> mylist = ['10', '12', '14']
>>> for elem in mylist:
        print elem 

10
12
14

To customize background image scaling create a resource like this:

<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
    android:gravity="center"
    android:src="@drawable/list_bkgnd" />

Then it will be centered in the view if used as background. There are also other flags: http://developer.android.com/guide/topics/resources/drawable-resource.html

Reason : Old versions of Tomcat 6 JSP compiler don't seem to be aware of JDK 8 constant pool enhancements - eg. method handles. New code in JDK 8u is using a method handle instead of creating an anonymous class. This will cause the method handle to be listed in the constant pool and the eclipse compiler will choke on this - https://bz.apache.org/bugzilla/show_bug.cgi?id=56613

Using the request module solved the issue.

// Include the request library for Node.js   
var request = require('request');
//  Basic Authentication credentials   
var username = "vinod"; 
var password = "12345";
var authenticationHeader = "Basic " + new Buffer(username + ":" + password).toString("base64");
request(   
{
url : "https://133-70-97-54-43.sample.com/feedSample/Query_Status_View/Query_Status/Output1?STATUS=Joined%20school",
headers : { "Authorization" : authenticationHeader }  
},
 function (error, response, body) {
 console.log(body); }  );         

I ran into this issue and it turned out the problem was that the jenkins service wasn't being run as the jenkins user. So running the commands as the jenkins user worked just fine.

You can use window.open to open a new window/tab(according to browser setting) in javascript.

By using document.write you can write HTML content to the opened window.

As usual, create an SSH key and paste the public key to GitHub. Add the private key to ssh-agent. (I assume this is what you have done.)

To check everything is correct, use ssh -T [email protected]

Next, don't forget to modify the remote point as follows:

git remote set-url origin [email protected]:username/your-repository.git

You can do it using JavaScript by triggering an ajax request to server to destroy the session on onbeforeunload event fired when we closes the browse tab or window or browser.

Easier solution;

#/bin/bash
if (( ${1:-2} >= 2 )); then
    echo "First parameter must be 0 or 1"
fi
# rest of script...

Output

$ ./test 
First parameter must be 0 or 1
$ ./test 0
$ ./test 1
$ ./test 4
First parameter must be 0 or 1
$ ./test 2
First parameter must be 0 or 1

Explanation

• (( )) - Evaluates the expression using integers.
• ${1:-2} - Uses parameter expansion to set a value of 2 if undefined.
• >= 2 - True if the integer is greater than or equal to two 2.

You could try:

hadoop fs -put /path/in/linux /hdfs/path

or even

hadoop fs -copyFromLocal /path/in/linux /hdfs/path

By default both put and copyFromLocal would upload directories recursively to HDFS.

I know I'm late to the party here, but I came here for opinions on my own desire to use state in actions, and then formed my own, when I realized what I think is the correct behavior.

This is where a selector makes the most sense to me. Your component that issues this request should be told wether it's time to issue it through selection.

export const SOME_ACTION = 'SOME_ACTION';
export function someAction(items) {
  return (dispatch) => {
    dispatch(anotherAction(items));
  }
}

It might feel like leaking abstractions, but your component clearly needs to send a message and the message payload should contain pertinent state. Unfortunately your question doesn't have a concrete example because we could work through a 'better model' of selectors and actions that way.

PATH: Answered long ago, however, it maybe more helpful to think of -p as "Path" (easier to remember), as in this causes mkdir to create every part of the path that isn't already there.

mkdir -p /usr/bin/comm/diff/er/fence

if /usr/bin/comm already exists, it acts like: mkdir /usr/bin/comm/diff mkdir /usr/bin/comm/diff/er mkdir /usr/bin/comm/diff/er/fence

As you can see, it saves you a bit of typing, and thinking, since you don't have to figure out what's already there and what isn't.

This function makes use of Mozilla's __count__ property if it is available as it is faster than iterating over every property.

function countProperties(obj) {
  var count = "__count__",
  hasOwnProp = Object.prototype.hasOwnProperty;

  if (typeof obj[count] === "number" && !hasOwnProp.call(obj, count)) {
    return obj[count];
  }
  count = 0;
  for (var prop in obj) {
    if (hasOwnProp.call(obj, prop)) {
      count++;
    }
  }
  return count;
};

countProperties({
  "1": 2,
  "3": 4,
  "5": 6
}) === 3;

As at MVC 5, if you wish to add any attributes you can simply do

 @Html.EditorFor(m => m.Name, new { htmlAttributes = new { @required = "true", @anotherAttribute = "whatever" } })

Update your connection string as shown below (without port variable as well):

MysqlConn.ConnectionString = "Server=127.0.0.1;Database=patholabs;Uid=pankaj;Pwd=master;"

Hope this helps...

i would see a very simple way

git reset --hard HEAD <YOUR COMMIT ID>

and then reset remote branch

git push origin -f

string myText =
    @"<div class=""firstLine""></div>
      <div class=""secondLine""></div>
      <div class=""thirdLine""></div>";

that's not it:

string myText =
@"<div class=\"firstLine\"></div>
  <div class=\"secondLine\"></div>
  <div class=\"thirdLine\"></div>";

If you are using lodash, its even simpler with takeRight.

_.takeRight(arr, 5);

To stop or start mysql on most linux systems the following should work:

/etc/init.d/mysqld stop

/etc/init.d/mysqld start

The other answers look good for accessing the mysql client from the command line.

Good luck!

Almost done. Quoting from http://docs.python.org/library/stdtypes.html?highlight=strip#str.strip

The chars argument is a string specifying the set of characters to be removed.

[...]

The chars argument is not a prefix or suffix; rather, all combinations of its values are stripped:

So the argument is not a regexp.

>>> string = '"" " " ""\\1" " "" ""'
>>> string.strip('"')
' " " ""\\1" " "" '
>>> 

Note, that this is not exactly what you requested, because it eats multiple quotes from both end of the string!

    const generateUniqueId = () => 'id_' + Date.now() + String(Math.random()).substr(2);

    // if u want to check for collision
    const arr = [];
    const checkForCollision = () => {
      for (let i = 0; i < 10000; i++) {
        const el = generateUniqueId();
        if (arr.indexOf(el) > -1) {
          alert('COLLISION FOUND');
        }
        arr.push(el);
      }
    };

Because the idea of tearing %DATE% and %TIME% apart and mashing them back together seems fragile at best, here's an alternative that uses a powershell oneliner:

for /f %i in ('powershell -c "get-date -format yyyy-MM-dd--HH-mm-ss"') do @set DATETIME=%i
set LOGFILE=my-script-%DATETIME%.txt

Reference for get-date is here, with format options for both .NET-style and UNIX-style.

Sometimes you have things other than text inside a table cell that you'd like to be horizontally centered. In order to do this, first set up some css...

<style>
    div.centered {
        margin: auto;
        width: 100%;
        display: flex;
        justify-content: center;
    }
</style>

Then declare a div with class="centered" inside each table cell you want centered.

<td>
    <div class="centered">
        Anything: text, controls, etc... will be horizontally centered.
    </div>
</td>

Use system property:

-Duser.timezone=UTC

I always prefer to use extension instead of free functions.

Swift 4

public extension DispatchQueue {

  private class func delay(delay: TimeInterval, closure: @escaping () -> Void) {
    let when = DispatchTime.now() + delay
    DispatchQueue.main.asyncAfter(deadline: when, execute: closure)
  }

  class func performAction(after seconds: TimeInterval, callBack: @escaping (() -> Void) ) {
    DispatchQueue.delay(delay: seconds) {
      callBack()
    }
  }

}

Use as follow.

DispatchQueue.performAction(after: 0.3) {
  // Code Here
}

If this works then please vote the answer.

As others have said you can use a console app to run when scheduled. What others haven't said is that you can this app trigger a cross process EventWaitHandle which you are waiting on in your main application.

Console App:

class Program
{
    static void Main(string[] args)
    {
        EventWaitHandle handle = 
            new EventWaitHandle(true, EventResetMode.ManualReset, "GoodMutexName");
        handle.Set();
    }
}

Main App:

private void Form1_Load(object sender, EventArgs e)
{
    // Background thread, will die with application
    ThreadPool.QueueUserWorkItem((dumby) => EmailWait());
}

private void EmailWait()
{
    EventWaitHandle handle = 
        new EventWaitHandle(false, EventResetMode.ManualReset, "GoodMutexName");

    while (true)
    {
        handle.WaitOne();

        SendEmail();

        handle.Reset();
    }
}

If building a temp table, move the ORDER BY clause from inside the temp table code block to the outside.

Not allowed:

SELECT * FROM (
SELECT A FROM Y
ORDER BY Y.A
) X;

Allowed:

SELECT * FROM (
SELECT A FROM Y
) X
ORDER BY X.A;

I know this answer is ridiculous, but consider just disabling this rule until the bugs are worked out or you've upgraded your tooling:

/* eslint-disable react/prop-types */ // TODO: upgrade to latest eslint tooling

Or disable project-wide in your eslintrc:

"rules": {
  "react/prop-types": "off"
}

just erase android/support/v4/util/TimeUtils.class

import React, { useRef, useState } from 'react'

function chooseFile() {
  const { current } = inputRef
  (current || { click: () => {}}).click()

...
<input

     setFile(e.target.files)

It's difficult to answer this question with the information given. Nothing looks particularly wrong with how you are using HashSet.

Well, I'll hazard a guess that it's not a compilation issue and, when you say "getting errors," you mean "not getting the behavior [you] want."

I'll also go out on a limb and suggest that maybe your Block's equals an hashCode methods are not properly overridden.

After adding -vm in eclipse.ini as shown below worked for me. Add it before -vmargs do not remove it

There was a jdk update which was causing this issue.

just change the extension to .bmp.

Do this:

ByteArrayOutputStream bytes = new ByteArrayOutputStream();
_bitmapScaled.compress(Bitmap.CompressFormat.PNG, 40, bytes);

//you can create a new file name "test.BMP" in sdcard folder.
File f = new File(Environment.getExternalStorageDirectory()
                        + File.separator + "test.bmp")

It'll sound that I'm just fooling around, but try it once and it'll get saved in BMP format. Cheers!

userType = (user.Type == 0) ? "Admin" : (user.type == 1) ? "User" : "Admin";

should do the trick.

Here's a concrete example:

Suppose you have a function that calculates the gravitational force acting on an object. If you don't know the formula, you can find it here. This function takes in the three necessary parameters as arguments.

Now, being on the earth, you only want to calculate forces for objects on this planet. In a functional language, you could pass in the mass of the earth to the function and then partially evaluate it. What you'd get back is another function that takes only two arguments and calculates the gravitational force of objects on earth. This is called currying.

SVG text background image

body {_x000D_
    background-image:url("data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' version='1.1' height='50px' width='120px'><text x='0' y='15' fill='red' font-size='20'>I love SVG!</text></svg>");_x000D_

<p>I hate SVG!</p><p>I hate SVG!</p><p>I hate SVG!</p><p>I hate SVG!</p>

Here is an indented version of the CSS so you can understand better. Note that this does not work, you need to use the single liner SVG from the snippet above instead:

body {
  background-image:url("data:image/svg+xml;utf8,
  <svg xmlns='http://www.w3.org/2000/svg' version='1.1'
       height='50px' width='120px'>
    <text x='0' y='15' fill='red' font-size='20'>I love SVG!</text>
  </svg>");
}

Not sure how portable this is (works on Firefox 31 and Chrome 36), and it is technically an image... but the source is inline and plain text, and it scales infinitely.

@senectus found that it works better on IE if you base64 encode it: https://stackoverflow.com/a/25593531/895245

Use Map interface and an implementation like HashMap

At least as far back as MySQL 5.5 you can use format:

SELECT FORMAT(123456789.123456789,2);
/* produces 123,456,789.12 */

SELECT FORMAT(123456789.123456789,2,'de_DE');
/* 
    produces 123.456.789,12
    note the swapped . and , for the de_DE locale (German-Germany) 
*/

From the MySQL docs: https://dev.mysql.com/doc/refman/5.5/en/string-functions.html#function_format

Available locales are listed elsewhere in the docs: https://dev.mysql.com/doc/refman/5.5/en/locale-support.html

There is not a program but you can make a batch file and run a command like that :

powershell "start-process 'C:\Program Files (x86)\IIS Express\iisexpress.exe' -workingdirectory 'C:\Program Files (x86)\IIS Express\' -windowstyle Hidden"

Future and Promise are proxy object for unknown result

Promise completes a Future

• Future - read/consumer of unknown result

• Promise - write/producer of unknown result.

//Future has a reference to Promise
Future -> Promise

As a producer I promise something and responsible for it

As a consumer who retrieved a promise I expect to have a result in future

As for Java CompletableFutures it is a Promise because you can set the result and also it implements Future

I've used Xavier's answer quite a bit. I want to add that restricting the package version to a specified range is easy and useful in the latest versions of NuGet.

For example, if you never want Newtonsoft.Json to be updated past version 3.x.x in your project, change the corresponding package element in your packages.config file to look like this:

<package id="Newtonsoft.Json" version="3.5.8" allowedVersions="[3.0, 4.0)" targetFramework="net40" />

Notice the allowedVersions attribute. This will limit the version of that package to versions between 3.0 (inclusive) and 4.0 (exclusive). Then, when you do an Update-Package on the whole solution, you don't need to worry about that particular package being updated past version 3.x.x.

The documentation for this functionality is here.

I had a similar issue. It is caused due the dependent package 'rJava'. This problem can be overcome by re-directing the R to use a different JAVA_HOME.

if(Sys.getenv("JAVA_HOME")!=""){
    Sys.setenv(JAVA_HOME="")
}
library(rJava)

This worked for me.

If you tried all of the other suggestions, and couldn't get any of them to work (like I couldn't), here's something you can try that may be useful.

HTML

<a class="refresh-this-frame" rel="#iframe-id-0">Refresh</a>
<iframe src="" id="iframe-id-0"></iframe>

JS

$('.refresh-this-frame').click(function() {
    var thisIframe = $(this).attr('rel');
    var currentState = $(thisIframe).attr('src');
    function removeSrc() {
        $(thisIframe).attr('src', '');
    }
    setTimeout (removeSrc, 100);
    function replaceSrc() {
        $(thisIframe).attr('src', currentState);
    }
    setTimeout (replaceSrc, 200);
});

I initially set out to try and save some time with RWD and cross-browser testing. I wanted to create a quick page that housed a bunch of iframes, organized into groups that I would show/hide at will. Logically you'd want to be able to easily and quickly refresh any given frame.

I should note that the project I am working on currently, the one in use in this test-bed, is a one-page site with indexed locations (e.g. index.html#home). That may have had something to do with why I couldn't get any of the other solutions to refresh my particular frame.

Having said that, I know it's not the cleanest thing in the world, but it works for my purposes. Hope this helps someone. Now if only I could figure out how to keep the iframe from scrolling the parent page each time there's animation inside iframe...

EDIT: I realized that this doesn't "refresh" the iframe like I'd hoped it would. It will reload the iframe's initial source though. Still can't figure out why I couldn't get any of the other options to work..

UPDATE: The reason I couldn't get any of the other methods to work is because I was testing them in Chrome, and Chrome won't allow you to access an iframe's content (Explanation: Is it likely that future releases of Chrome support contentWindow/contentDocument when iFrame loads a local html file from local html file?) if it doesn't originate from the same location (so far as I understand it). Upon further testing, I can't access contentWindow in FF either.

AMENDED JS

$('.refresh-this-frame').click(function() {
    var targetID = $(this).attr('rel');
    var targetSrc = $(targetID).attr('src');
    var cleanID = targetID.replace("#","");     
    var chromeTest = ( navigator.userAgent.match(/Chrome/g) ? true : false );
    var FFTest = ( navigator.userAgent.match(/Firefox/g) ? true : false );      
    if (chromeTest == true) {
        function removeSrc() {
            $(targetID).attr('src', '');
        }
        setTimeout (removeSrc, 100);
        function replaceSrc() {
            $(targetID).attr('src', targetSrc);
        }
        setTimeout (replaceSrc, 200);
    }
    if (FFTest == true) {
        function removeSrc() {
            $(targetID).attr('src', '');
        }
        setTimeout (removeSrc, 100);
        function replaceSrc() {
            $(targetID).attr('src', targetSrc);
        }
        setTimeout (replaceSrc, 200);
    }       
    if (chromeTest == false && FFTest == false) {
        var targetLoc = (document.getElementById(cleanID).contentWindow.location).toString();
        function removeSrc() {
            $(targetID).attr('src', '');
        }
        setTimeout (removeSrc, 100);
        function replaceSrc2() {
            $(targetID).attr('src', targetLoc);
        }
        setTimeout (replaceSrc2, 200);
    }
});

Just type this in the terminal:

export NODE_OPTIONS="--max-old-space-size=8192"

Always remember that in case of checked exception you can catch only after throwing the exception(either you throw or any inbuilt method used in your code can throw) ,but in case of unchecked exception You an catch even when you have not thrown that exception.

Try

if($('#car2').is(':hidden'))
{  
    alert('car 2 is hidden');       
}

to pass the event object:

<p id="p" onclick="doSomething(event)">

to get the clicked child element (should be used with event parameter:

function doSomething(e) {
    e = e || window.event;
    var target = e.target || e.srcElement;
    console.log(target);
}

to pass the element itself (DOMElement):

<p id="p" onclick="doThing(this)">

see live example on jsFiddle.

You can specify the name of the event as above, but alternatively your handler can access the event parameter as described here: "When the event handler is specified as an HTML attribute, the specified code is wrapped into a function with the following parameters". There's much more additional documentation at the link.

Small hint which other people didn't talk about: git doesn't record changes if you add empty folders in your project folder. That's it, I was adding empty folders with random names to check wether it was recording changes, it wasn't. But it started to do it as soon as I began adding files in them. Cheers.

With EasyGui:

import easygui
print(easygui.fileopenbox())

To install:

pip install easygui

Demo:

import easygui
easygui.egdemo()

Try this:

XmlDocument doc = new XmlDocument();
doc.Load(@"C:\Path\To\Xml\File.xml");

Or alternatively if you have the XML in a string use the LoadXml method.

Once you have it loaded, you can use SelectNodes and SelectSingleNode to query specific values, for example:

XmlNode node = doc.SelectSingleNode("//Company/Email/text()");
// node.Value contains "[email protected]"

Finally, note that your XML is invalid as it doesn't contain a single root node. It must be something like this:

<Data>
    <Employee>
        <Name>Test</Name>
        <ID>123</ID>
    </Employee>
    <Company>
        <Name>ABC</Name>
        <Email>[email protected]</Email>
    </Company>
</Data>

If you are unable to set this up in IIS for whatever reason, I'd make an HTTP module that does the redirect for you:

using System;
using System.Web;

namespace HttpsOnly
{
    /// <summary>
    /// Redirects the Request to HTTPS if it comes in on an insecure channel.
    /// </summary>
    public class HttpsOnlyModule : IHttpModule
    {
        public void Init(HttpApplication app)
        {
            // Note we cannot trust IsSecureConnection when 
            // in a webfarm, because usually only the load balancer 
            // will come in on a secure port the request will be then 
            // internally redirected to local machine on a specified port.

            // Move this to a config file, if your behind a farm, 
            // set this to the local port used internally.
            int specialPort = 443;

            if (!app.Context.Request.IsSecureConnection 
               || app.Context.Request.Url.Port != specialPort)
            {
               app.Context.Response.Redirect("https://" 
                  + app.Context.Request.ServerVariables["HTTP_HOST"] 
                  + app.Context.Request.RawUrl);    
            }
        }

        public void Dispose()
        {
            // Needed for IHttpModule
        }
    }
}

Then just compile it to a DLL, add it as a reference to your project and place this in web.config:

 <httpModules>
      <add name="HttpsOnlyModule" type="HttpsOnly.HttpsOnlyModule, HttpsOnly" />
 </httpModules>

PAUSE

Yes, you can do almost that:

SELECT dbo.GetBusinessDays(a.opendate,a.closedate) as BusinessDays
FROM account a
WHERE...

Should just be something like:

// Gets the number of elements with class yourClass
var numItems = $('.yourclass').length

As a side-note, it is often beneficial to check the length property before chaining a lot of functions calls on a jQuery object, to ensure that we actually have some work to perform. See below:

var $items = $('.myclass');
// Ensure we have at least one element in $items before setting up animations
// and other resource intensive tasks.
if($items.length)
{
  $items.animate(/* */)
    // It might also be appropriate to check that we have 2 or more
    // elements returned by the filter-call before animating this subset of 
    // items.
    .filter(':odd')
      .animate(/* */)
      .end()
    .promise()
    .then(function () { 
       $items.addClass('all-done');
    });
}

You need to add a reference to System.Web.Extensions.dll in project for System.Web.Script.Serialization error.

You cannot add methods to an existing type unless the existing type is marked as partial, you can only add methods that appear to be a member of the existing type through extension methods. Since this is the case you cannot add static methods to the type itself since extension methods use instances of that type.

There is nothing stopping you from creating your own static helper method like this:

static class DateTimeHelper
{
    public static DateTime Tomorrow
    {
        get { return DateTime.Now.AddDays(1); }
    }
}

Which you would use like this:

DateTime tomorrow = DateTimeHelper.Tomorrow;

You do it by stacking case labels:

switch(myvar)
{
    case 2:
    case 5:
    ...
    break;

    case 7: 
    case 12:
    ...
    break;
    ...
}

1G=G. That should indent all the lines in the file. 1G takes you the first line, = will start the auto-indent and the final G will take you the last line in the file.

Progress Bar in Layout

<ProgressBar 
               android:id="@+id/download_progressbar"
               android:layout_width="200dp"
               android:layout_height="24dp"
               android:background="@drawable/download_progress_bg_track"
               android:progressDrawable="@drawable/download_progress_style"
               style="?android:attr/progressBarStyleHorizontal"
               android:indeterminate="false"
               android:indeterminateOnly="false" />

download_progress_style.xml

      android:drawable="@drawable/store_download_progress" />

After clicking on Properties of any installer(.exe) which block your application to install (Windows Defender SmartScreen prevented an unrecognized app ) for that issue i found one solution

1. Right click on installer(.exe)
2. Select properties option.
3. Click on checkbox to check Unblock at the bottom of Properties.

This solution work for Heroku CLI (heroku-x64) installer(.exe)

What you want is org.mockito.Mockito.CALLS_REAL_METHODS according to the docs:

/**
 * Optional <code>Answer</code> to be used with {@link Mockito#mock(Class, Answer)}
 * <p>
 * {@link Answer} can be used to define the return values of unstubbed invocations.
 * <p>
 * This implementation can be helpful when working with legacy code.
 * When this implementation is used, unstubbed methods will delegate to the real implementation.
 * This is a way to create a partial mock object that calls real methods by default.
 * <p>
 * As usual you are going to read <b>the partial mock warning</b>:
 * Object oriented programming is more less tackling complexity by dividing the complexity into separate, specific, SRPy objects.
 * How does partial mock fit into this paradigm? Well, it just doesn't... 
 * Partial mock usually means that the complexity has been moved to a different method on the same object.
 * In most cases, this is not the way you want to design your application.
 * <p>
 * However, there are rare cases when partial mocks come handy: 
 * dealing with code you cannot change easily (3rd party interfaces, interim refactoring of legacy code etc.)
 * However, I wouldn't use partial mocks for new, test-driven & well-designed code.
 * <p>
 * Example:
 * <pre class="code"><code class="java">
 * Foo mock = mock(Foo.class, CALLS_REAL_METHODS);
 *
 * // this calls the real implementation of Foo.getSomething()
 * value = mock.getSomething();
 *
 * when(mock.getSomething()).thenReturn(fakeValue);
 *
 * // now fakeValue is returned
 * value = mock.getSomething();
 * </code></pre>
 */

Thus your code should look like:

import org.junit.Test;
import static org.mockito.Mockito.*;
import static org.junit.Assert.*;

public class StockTest {

    public class Stock {
        private final double price;
        private final int quantity;

        Stock(double price, int quantity) {
            this.price = price;
            this.quantity = quantity;
        }

        public double getPrice() {
            return price;
        }

        public int getQuantity() {
            return quantity;
        }

        public double getValue() {
            return getPrice() * getQuantity();
        }
    }

    @Test
    public void getValueTest() {
        Stock stock = mock(Stock.class, withSettings().defaultAnswer(CALLS_REAL_METHODS));
        when(stock.getPrice()).thenReturn(100.00);
        when(stock.getQuantity()).thenReturn(200);
        double value = stock.getValue();

        assertEquals("Stock value not correct", 100.00 * 200, value, .00001);
    }
}

The call to Stock stock = mock(Stock.class); calls org.mockito.Mockito.mock(Class<T>) which looks like this:

 public static <T> T mock(Class<T> classToMock) {
    return mock(classToMock, withSettings().defaultAnswer(RETURNS_DEFAULTS));
}

The docs of the value RETURNS_DEFAULTS tell:

/**
 * The default <code>Answer</code> of every mock <b>if</b> the mock was not stubbed.
 * Typically it just returns some empty value. 
 * <p>
 * {@link Answer} can be used to define the return values of unstubbed invocations. 
 * <p>
 * This implementation first tries the global configuration. 
 * If there is no global configuration then it uses {@link ReturnsEmptyValues} (returns zeros, empty collections, nulls, etc.)
 */

Use setMaxDate().

For example, replace return new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay) statement with something like this:

    DatePickerDialog dialog = new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
    dialog.getDatePicker().setMaxDate(new Date().getTime());
    return dialog;

You can quit, either by pressing the Back button or by calling finish() in your Activity. Just call finish() from a MenuItem if you want to explicitly kill it off.

Romain isn't saying it can't be done, just that it's pointless — users don't need to care about quitting or saving their work or whatever, as the way the application lifecycle works encourages you to write smart software that automatically saves and restores its state no matter what happens.

The character is a backslash \

From the bash manual:

The backslash character ‘\’ may be used to remove any special meaning for the next character read and for line continuation.

If you want to modify the line width flexibly you can use "scale_size_manual," this is the same procedure for picking the color, fill, alpha, etc.

library(ggplot2)
library(tidyr)

x = seq(0,10,0.05)

df <- data.frame(A = 2 * x + 10,
                 B = x**2 - x*6,
                 C = 30 - x**1.5,
                 X = x)


df = gather(df,A,B,C,key="Model",value="Y")


ggplot( df, aes (x=X, y=Y, size=Model, colour=Model ))+
  geom_line()+
  scale_size_manual( values = c(4,2,1) ) +
  scale_color_manual( values = c("orange","red","navy") ) 

a = 10 * [0]

gives you an array of length 10, filled with zeroes.

I noticed the exact same issue when logging onto servers running Red Hat from an OSX Lion machine.

Try adding or editing the ~/.profile file for it to correctly export your locale settings upon initiating a new session.

export LC_ALL=en_US.UTF-8  
export LANG=en_US.UTF-8

These two lines added to the file should suffice to set the locale [replace en_US for your desired locale, and check beforehand that it is indeed installed on your system (locale -a)].

After that, you can start a new session and check using locale:

$ locale

The following should be the output:

LANG="en_US.UTF-8"  
LC_COLLATE="en_US.UTF-8"  
LC_CTYPE="en_US.UTF-8"  
LC_MESSAGES="en_US.UTF-8"  
LC_MONETARY="en_US.UTF-8"  
LC_NUMERIC="en_US.UTF-8"  
LC_TIME="en_US.UTF-8"  
LC_ALL="en_US.UTF-8"  

As I know there are 2 different graphic formats:

1. Raster graphics (uses bitmaps) and is used in JPEG, PNG, APNG, GIF, and MPEG4 file format.
2. Vector graphics (uses points, lines, curves and other shapes). Vector graphics are used in the SVG, EPS, PDF or AI graphic file formats.

So if you need to use an image stored in SVG File in your Xcode I would suggest:

1. Convert SVG file to PDF. I used https://document.online-convert.com/convert/svg-to-pdf

2. Use Xcode to manage you PDF file.

You can use the -notmatch operator to get the lines that don't have the characters you are interested in.

     Get-Content $FileName | foreach-object { 
     if ($_ -notmatch $arrayofStringsNotInterestedIn) { $) }

After the update you have done,

1. its first calling the FirstAjax action with default HttpGet request and renders the blank Html view . (Earlier you were not having it)
2. later on loading of DOM elements of that view your Ajax call get fired and displays alert.

Earlier you were only returning JSON to browser without rendering any HTML. Now it has a HTML view rendered where it can get your JSON Data.

You can't directly render JSON its plain data not HTML.

You can use:

Start-Process -FilePath "C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe" -ArgumentList "-verb:sync -source:dbfullsql="Data Source=mysource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;" -dest:dbfullsql="Data Source=.\mydestsource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;",computername=10.10.10.10,username=administrator,password=adminpass"

The key thing to note here is that FilePath must be in position 0, according to the Help Guide. To invoke the Help guide for a commandlet, just type in Get-Help <Commandlet-name> -Detailed . In this case, it is Get-Help Start-Process -Detailed.

C++ is a programming language and Visual C++ is an IDE for developing with languages such as C and C++.

VC++ contains tools for, amongst others, developing against the .net framework and the Windows API.

Bare bones, but confirmed working, example:

<script type="text/javascript">

<form action="" onsubmit="mysubmit();return false">
    <input type="submit" onclick="clicked='Save'" value="Save" />
    <input type="submit" onclick="clicked='Add'" value="Add" />
</form>

You can export the query results to a text file (or insert statements, or even pdf) by right-clicking on Query Result row (any row) and choose Export

You should not be able to notice the difference even if there is any. Besides, in practice, you'll have to do an additional a + 1 or a - 1 to make the condition stand unless you're going to use some magic constants, which is a very bad practice by all means.

when you select run configuration, there is a JRE tap up next the main tap, select "Workspace default JRE(JDK1.7)".

Extract single value from JSON response Python

Try this

import json
import sys

#load the data into an element
data={"test1" : "1", "test2" : "2", "test3" : "3"}

#dumps the json object into an element
json_str = json.dumps(data)

#load the json to a string
resp = json.loads(json_str)

#print the resp
print (resp)

#extract an element in the response
print (resp['test1'])

If you do not care about sign your program when you publish, just right click your project then choose Properties --> Signing --> un-check Sign the ClickOnce manifest . I had the same issue when building my program on another machine which did not have ClickOne.

>>> "    xyz     ".rstrip()
'    xyz'

There is more about rstrip in the documentation.

You can add spring-context dependency for spring jars. You will get the following jars along with it.

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>5.0.5.RELEASE</version>
</dependency>

if you also want web components, you can use spring-webmvc dependency.

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>5.0.5.RELEASE</version>
</dependency>

You can use whatever version of that you want. I have used 5.0.5.RELEASE here.

Due to PEP-0469 which renamed iteritems() to items() and PEP-3113 which removed Tuple parameter unpacking, in Python 3.x you should write Martijn Pieters? answer like this:

my_dictionary = dict(map(lambda item: (item[0], f(item[1])), my_dictionary.items()))

$client = new \GuzzleHttp\Client();
$request = $client->post('http://demo.website.com/api', [
    'body' => json_encode($dataArray)
]);
$response = $request->getBody();

If you're running your program on PyCharm on Windows, there is a known bug, because PyCharm simply doesn't add env-related paths to PATH.

The issue is fixed in the 2019.1 Early Access Preview (EAP) build.

For me installing the EAP fixed the issue.

1. Change "INSERT URL" to whatever website holds the shared content.
2. Change "INSERT TITLE" to the title of the article.
3. Change "INSERT SUMMARY" to a short summary of the article.
4. Change "INSERT IMAGE URL" to an image that will be shared with the rest of the content.
5. Change "INSERT DOMAIN NAME" to your domain name.
6. Change "INSERT PUBLISHERID" to your publisher ID (if you have an account, if not, remove "[INSERT PUBLISHERID]" or sign up!)

If you are using this on an email newsletter, make sure you add our sharing buttons to the destination page. This will ensure that you get complete sharing analytics for your page. Make sure you replace "INSERT PUBLISHERID" with your own.

Yes! Finally! I just tried it with Chrome, Version 66.0.3359.170 (Official Build) (64-bit) on Mac.

You can change the values in the scopes as in the first picture, or with the console as in the second picture.

You may need to add a JDK (Java Development Kit) to the installed JRE's within Eclipse

Go to Window->Preferences->Java->Installed JRE's

In the Name column if you do not have a JDK as your default, then you will need to add it.

Click the "Add" Button and locate the JDK on your machine. You may find it in this location: C:\Program Files\Java\jdk1.x.y
Where x and y are numbers.

If there are no JDK's installed on your machine then download and install the Java SE (Standard Edition) from the Oracle website.

Then do the steps above again. Be sure that it is set as the default JRE to use.

Then go back to the Projects->Generate Javadoc... dialog

Now it should work.

Good Luck.

Try this:

sudo dpkg-reconfigure mysql-server-{version_number}

version_number should be mysql version number. For example

sudo dpkg-reconfigure mysql-server-5.6

Then access mysql like this:

mysql -u root -p

Using Path is the recommended way since Python 3:

from pathlib import Path
print("File      Path:", Path(__file__).absolute())
print("Directory Path:", Path().absolute()) # Directory of current working directory, not __file__  

Documentation: pathlib

Note: If using Jupyter Notebook, __file__ doesn't return expected value, so Path().absolute() has to be used.

You are not writing your code inside any function, you can return from functions only. Remove return statement and just print the value you want.

This is a more efficient version of the solution from @Kramb. The existence check is redundant as the update where clause already handles this. Instead you just grab the rowcount and compare to batchsize.

Also note @Kramb solution didn't filter out already updated rows from the next iteration hence it would be an infinite loop.

Also uses the modern batch size syntax instead of using rowcount.

DECLARE @batchSize INT, @rowsUpdated INT
SET @batchSize = 1000;
SET @rowsUpdated = @batchSize; -- Initialise for the while loop entry

WHILE (@batchSize = @rowsUpdated)
BEGIN
    UPDATE TOP (@batchSize) TableName
    SET Value = 'abc1'
    WHERE Parameter1 = 'abc' AND Parameter2 = 123 and Value <> 'abc1';

    SET @rowsUpdated = @@ROWCOUNT;
END

$("a").click(function(){
                alert('disabled');
                return false;

}); 

If you want to add more than one:

hash = {:a => 1, :b => 2}
hash.merge! :c => 3, :d => 4
p hash

Finaly I found another answer for this problem. and this is working for me. Just add below datas to the your webconfig file.

<configuration>
 <system.webServer>
  <security>
   <requestFiltering>
    <verbs allowUnlisted="true">
     <add verb="OPTIONS" allowed="false" />
    </verbs>
   </requestFiltering>
  </security>
 </system.webServer>
</configuration>

Form more information, you can visit this web site: http://www.iis.net/learn/manage/configuring-security/use-request-filtering

if you want to test your web site, is it working or not... You can use "HttpRequester" mozilla firefox plugin. for this plugin: https://addons.mozilla.org/En-us/firefox/addon/httprequester/

It looks like you're trying to scale the background image? There's a great article in the reference bellow where you can use css3 to achieve this.

And if I miss-read the question then I humbly accept the votes down. (Still good to know though)

Please consider the following code:

#some_div_or_body { 
   background: url(images/bg.jpg) no-repeat center center fixed; 
   -webkit-background-size: cover;
   -moz-background-size: cover;
   -o-background-size: cover;
   background-size: cover;
}

This will work on all major browsers, of course it doesn't come easy on IE. There are some workarounds however such as using Microsoft's filters:

filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='.myBackground.jpg', sizingMethod='scale');
-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='myBackground.jpg', sizingMethod='scale')";

There are some alternatives that can be used with a little bit peace of mind by using jQuery:

HTML

<img src="images/bg.jpg" id="bg" alt="">

CSS

#bg { position: fixed; top: 0; left: 0; }
.bgwidth { width: 100%; }
.bgheight { height: 100%; }

jQuery:

 $(window).load(function() {    

var theWindow        = $(window),
    $bg              = $("#bg"),
    aspectRatio      = $bg.width() / $bg.height();

function resizeBg() {

    if ( (theWindow.width() / theWindow.height()) < aspectRatio ) {
        $bg
            .removeClass()
            .addClass('bgheight');
    } else {
        $bg
            .removeClass()
            .addClass('bgwidth');
    }

}

theWindow.resize(resizeBg).trigger("resize");

});

I hope this helps!

When having a function write a function that changes different global variables values it is not always myfirstname it is whatever happens to be passing through. Try this worked for me.

_{Run in jsfiddle}

var jack = 'jill';
function window_getVarName(what)
{
  for (var name in window)
  {
    if (window[name]==what)
    return(name);
  }
  return("");
}
document.write(window_getVarName(jack));

Will write to the window 'jack'.

List<String> items= Stream.of(commaSeparated.split(","))
     .map(String::trim)
     .collect(toList());

This should do what you want:

preg_replace("/[^0-9]/", "",$c);

you could take a look at the w3 how to, i think you will find it helpful

your link tag attribute should be rel="icon"

You can use Joda time library for Java. It would be much easier to calculate time-diff between dates with it.

Sample snippet for time-diff:

Days d = Days.daysBetween(startDate, endDate);
int days = d.getDays();

First - Copy CON SETUPDAY.001 SET WORKDAY=^Z (very important - no cr/lf)

DATE /T >SETUPDAY.002
COPY SETUPDAY.001+SETUPDAY.002 NEWDAY.BAT >nul
CALL NEWDAY.BAT

SET WEEKDAY=%WORKDAY:~0,3%
SET MDY=%WORKDAY:~4,10%

USE %WEEKDAY% IN YOUR SCRIPT

I am using this function:

public static int[][] copy(final int[][] array) {
    if (array != null) {
        final int[][] copy = new int[array.length][];

        for (int i = 0; i < array.length; i++) {
            final int[] row = array[i];

            copy[i] = new int[row.length];
            System.arraycopy(row, 0, copy[i], 0, row.length);
        }

        return copy;
    }

    return null;
}

The big advantage of this approach is that it can also copy arrays that don't have the same row count such as:

final int[][] array = new int[][] { { 5, 3, 6 }, { 1 } };

I created a category around UIButton to be able to set the background color of the button and set the state. You might find this useful.

@implementation  UIButton (ButtonMagic)

- (void)setBackgroundColor:(UIColor *)backgroundColor forState:(UIControlState)state {
    [self setBackgroundImage:[UIButton imageFromColor:backgroundColor] forState:state];
}

+ (UIImage *)imageFromColor:(UIColor *)color {
    CGRect rect = CGRectMake(0, 0, 1, 1);
    UIGraphicsBeginImageContext(rect.size);
    CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextSetFillColorWithColor(context, [color CGColor]);
    CGContextFillRect(context, rect);
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return image;
}

This will be part of a set of helper categories I'm open sourcing this month.

Swift 2.2

extension UIImage {
static func fromColor(color: UIColor) -> UIImage {
    let rect = CGRect(x: 0, y: 0, width: 1, height: 1)
    UIGraphicsBeginImageContext(rect.size)
    let context = UIGraphicsGetCurrentContext()
    CGContextSetFillColorWithColor(context, color.CGColor)
    CGContextFillRect(context, rect)
    let img = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return img
  }
}

Swift 3.0

extension UIImage {
    static func from(color: UIColor) -> UIImage {
        let rect = CGRect(x: 0, y: 0, width: 1, height: 1)
        UIGraphicsBeginImageContext(rect.size)
        let context = UIGraphicsGetCurrentContext()
        context!.setFillColor(color.cgColor)
        context!.fill(rect)
        let img = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return img!
    }
}

Use as

let img = UIImage.from(color: .black)

It's not possible to access camera of your development machine to be used as simulator camera. Camera functionality is not available in any iOS version and any Simulator. You will have to use device for testing camera purpose.

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

Check your console. It says java.lang.SecurityException issue. Change your 'package name'. I changed my package name from 'java.assessment' to 'assesment' and it worked for me. If somebody knows the root cause , let me know please.

The answer is "pyrsvg" - a Python binding for librsvg.

There is an Ubuntu python-rsvg package providing it. Searching Google for its name is poor because its source code seems to be contained inside the "gnome-python-desktop" Gnome project GIT repository.

I made a minimalist "hello world" that renders SVG to a cairo surface and writes it to disk:

import cairo
import rsvg

img = cairo.ImageSurface(cairo.FORMAT_ARGB32, 640,480)

ctx = cairo.Context(img)

## handle = rsvg.Handle(<svg filename>)
# or, for in memory SVG data:
handle= rsvg.Handle(None, str(<svg data>))

handle.render_cairo(ctx)

img.write_to_png("svg.png")

Update: as of 2014 the needed package for Fedora Linux distribution is: gnome-python2-rsvg. The above snippet listing still works as-is.

You can amend your !DOCTYPE declaration (i.e. DTD) to allow it, so that the [XML] document will still be valid:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
[
  <!ATTLIST tag myAttri CDATA #IMPLIED>
]>

#IMPLIED means it is an optional attribute, or you could use #REQUIRED, etc.

More information is in DTD - Attributes.

A much simpler way to do this is to use vCenter Converter Standalone Client and do a P2V but in this case a V2V. It is much faster than copying the entire VM files onto some storage somewhere and copy it onto your new vCenter. It takes a long time to copy or exporting it to an OVF template and then import it. You can set your vCenter Converter Standalone Client to V2V in one step and synchronize and then have it power up the VM on the new Vcenter and shut off on the old vCenter. Simple.

For me using this method I was able to move a VM from one vCenter to another vCenter in about 30 minutes as compared to copying or exporting which took over 2hrs. Your results may vary.

This process below, from another responder, would work even better if you can present that datastore to ESXi servers on the vCenter and then follow step 2. Eliminating having to copy all the VMs then follow rest of the process.

1. Copy all of the cloned VM's files from its directory, and place it on its destination datastore.
2. In the VI client connected to the destination vCenter, go to the Inventory->Datastores view.
3. Open the datastore browser for the datastore where you placed the VM's files.
4. Find the .vmx file that you copied over and right-click it.
5. Choose 'Register Virtual Machine', and follow whatever prompts ensue. (Depending on your version of vCenter, this may be 'Add to Inventory' or some other variant)

You can use templated interfaces like this:

interface Map<T> {
    [K: string]: T;
}

let dict: Map<number> = {};
dict["one"] = 1;

your problem is why your code doesn't work.

this your code:

Firebase ref = new Firebase(FIREBASE_URL);

  ref.addValueEventListener(new ValueEventListener() {
      @Override
      public void onDataChange(DataSnapshot snapshot) {
          Log.e("Count " ,""+snapshot.getChildrenCount());
          for (DataSnapshot postSnapshot: snapshot.getChildren()) {
            <YourClass> post = postSnapshot.getValue(<YourClass>.class);
            Log.e("Get Data", post.<YourMethod>());
          }
      }
      @Override
      public void onCancelled(FirebaseError firebaseError) {
          Log.e("The read failed: " ,firebaseError.getMessage());
      }
  })

you miss the simplest thing: getChildren()

FirebaseDatabase db = FirebaseDatabase.getInstance();
DatabaseReference reference = FirebaseAuth.getInstance().getReference("Donald Trump");

reference.addValueEventListener(new ValueEventListener() {
   @Override
   public void onDataChange(DataSnapshot dataSnapshot) {

            int count = (int) dataSnapshot.getChildrenCount(); // retrieve number of childrens under Donald Trump

            String[] hairColors = new String[count];

            index = 0;
            for (DataSnapshot datas : dataSnapshot.getChildren()){

                hairColors[index] = datas.getValue(String.class);

            }
            index ++

            for (int i = 0; i < count; i++)
            Toast(MainActivity.this, "hairColors : " + hairColors[i], toast.LENGTH_SHORT).show();

            }

    }

        @Override
        public void onCancelled(DatabaseError databaseError) {

        }

    });

If I understand correctly, you want to find a pattern between two line numbers. The awk one-liner could be

awk '/whatev/ && NR >= 1234 && NR <= 5555' file

You don't need to run grep followed by sed.

Perl one-liner:

perl -ne 'if (/whatev/ && $. >= 1234 && $. <= 5555') {print}' file

Here is the tutorial of achieving the result.

Example:

if(!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest')
{    
  exit;    
}
continue;

This checks if the HTTP_X_REQUESTED_WITH parameter is not empty and if it's equal to xmlhttprequest, then it will exit from the script.

You could also try:

if ((!isset($action)) || !($action == "add" || $action == "delete")) {
  // Do your stuff
}

The correct syntax is:

import sampleModule = require('modulename');

or

import * as sampleModule from 'modulename';

Then compile your TypeScript with --module commonjs.

If the package doesn't come with an index.d.ts file and its package.json doesn't have a "typings" property, tsc will bark that it doesn't know what 'modulename' refers to. For this purpose you need to find a .d.ts file for it on http://definitelytyped.org/, or write one yourself.

If you are writing code for Node.js you will also want the node.d.ts file from http://definitelytyped.org/.

Note:The cause of the quotes is that when data moves from excel to clipboard it is fully complying with CSV standards which include quoting values that include tabs, new lines etc (and double-quote characters are replaced with two double-quote characters )

So another approach, especially as in OP's case when tabs/new lines are due to the formula, is to use alternate characters for tabs and hard returns. I use ascii Unit Separator =char(31) for tabs and ascii Record Separator =char(30) for new lines.

Then pasting into text editor will not involve the extra CSV rules and you can do a quick search and replace to convert them back again.

If the tabs/new lines are embedded in the data, you can do a search and replace in excel to convert them.

Whether using formula or changing the data, the key to choosing delimiters is never use characters that can be in the actual data. This is why I recommend the low level ascii characters.

in linux os such as Debian or Ubutu you can simply try this ways, for first time remove phpmyadmin with --purge parameter:

sudo apt-get remove --purge phpmyadmin

then install again

sudo apt-get install phpmyadmin      

thats work fine :)

from os import system, remove
from uuid import uuid4

def bash_(shell_command: str) -> tuple:
    """

    :param shell_command: your shell command
    :return: ( 1 | 0, stdout)
    """

    logfile: str = '/tmp/%s' % uuid4().hex
    err: int = system('%s &> %s' % (shell_command, logfile))
    out: str = open(logfile, 'r').read()
    remove(logfile)
    return err, out

# Example: 
print(bash_('cat /usr/bin/vi | wc -l'))
>>> (0, '3296\n')```

On my machine:

C:\Program Files (x86)\OpenERP 6.1-20121026-233219\PostgreSQL\data

Here's an alternative solution:

>>> import pyexcel as pe
>>> text="""1,2,3
... a,b,c
... d,e,f"""
>>> s = pe.load_from_memory('csv', text)
>>> s
Sheet Name: csv
+---+---+---+
| 1 | 2 | 3 |
+---+---+---+
| a | b | c |
+---+---+---+
| d | e | f |
+---+---+---+
>>> s.to_array()
[[u'1', u'2', u'3'], [u'a', u'b', u'c'], [u'd', u'e', u'f']]

Here's the documentation

As adapted from Erika Ehrli's blog, this should do it:

XmlDocument doc = new XmlDocument();
doc.LoadXml("<item><name>wrench</name></item>");
// Save the document to a file and auto-indent the output.
using (XmlTextWriter writer = new XmlTextWriter("data.xml", null)) {
    writer.Formatting = Formatting.Indented;
    doc.Save(writer);
}

Bad: (jsHint will throw a error)

for (var name in item) {
    console.log(item[name]);
}

Good:

for (var name in item) {
  if (item.hasOwnProperty(name)) {
    console.log(item[name]);
  }
}

The 'find' method can be used to get all child inputs of a container that has already been cached to save looking it up again (whereas the 'children' method will only get the immediate children). e.g.

var panel= $("#panel");
var inputs = panel.find("input");

You can use the following code to get last day of the month

public static String getLastDayOfTheMonth(String date) {
        String lastDayOfTheMonth = "";

        SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yyyy");
        try{
        java.util.Date dt= formatter.parse(date);
        Calendar calendar = Calendar.getInstance();  
        calendar.setTime(dt);  

        calendar.add(Calendar.MONTH, 1);  
        calendar.set(Calendar.DAY_OF_MONTH, 1);  
        calendar.add(Calendar.DATE, -1);  

        java.util.Date lastDay = calendar.getTime();  

        lastDayOfTheMonth = formatter.format(lastDay);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return lastDayOfTheMonth;
    }

Well I think you just need to add a quantifier to each pattern. Also the carriage-return thing is a little funny:

text.replace(/[^a-z0-9]+|\s+/gmi, " ");

edit The \s thing matches \r and \n too.

For a virtual function you need to provide implementation in the base class. However derived class can override this implementation with its own implementation. Normally , for pure virtual functions implementation is not provided. You can make a function pure virtual with =0 at the end of function declaration. Also, a class containing a pure virtual function is abstract i.e. you can not create a object of this class.

In App.js add the below code and try

window.location.pathname

I know this is buried, but I had caused this issue when I moved a database without giving the NT Service\MSQLSERVER account rights to the directory I moved the database files to. Giving the rights and restarting SQLServer did the trick.

Since I cannot comment, adding this note in addition to @jethro answer.

I found out that you also need to do the FOREIGN KEY line as the last part of create the table statement, otherwise you will get a syntax error when installing your app. What I mean is, you cannot do something like this:

private static final String TASK_TABLE_CREATE = "create table "
    + TASK_TABLE + " (" + TASK_ID
    + " integer primary key autoincrement, " + TASK_TITLE
    + " text not null, " + TASK_NOTES + " text not null, "
+ TASK_CAT + " integer,"
+ " FOREIGN KEY ("+TASK_CAT+") REFERENCES "+CAT_TABLE+" ("+CAT_ID+"), "
+ TASK_DATE_TIME + " text not null);";

Where I put the TASK_DATE_TIME after the foreign key line.

You can use the 're' module in Python 3.
If you indeed do, use this:

re.search('\s', word)

This should return either 'true' if there's a match, or 'false' if there isn't any.

This one automatically excludes the trailing comma, unlike most of the other answers.

DECLARE @csv VARCHAR(1000)

SELECT @csv = COALESCE(@csv + ',', '') + ModuleValue
FROM Table_X
WHERE ModuleID = @ModuleID

(If the ModuleValue column isn't already a string type then you might need to cast it to a VARCHAR.)

You're probably talking about unobtrusive Javascript, which would look like this:

<a href="#" id="someLink">link</a>

with the logic in a central javascript file looking something like this:

$('#someLink').click(function(){
    popup('/map/', 300, 300, 'map'); 
    return false;
});

The advantages are

• behaviour (Javascript) is separated from presentation (HTML)
• no mixing of languages
• you're using a javascript framework like jQuery that can handle most cross-browser issues for you
• You can add behaviour to a lot of HTML elements at once without code duplication

Just simple use

=Format(today(), "dd/MM/yyyy")

will solve your problem.

The closest equivalent to Java's toString is to implement __str__ for your class. Put this in your class definition:

def __str__(self):
     return "foo"

You may also want to implement __repr__ to aid in debugging.

See here for more information:

• Special Method Names - Basic Customization

Your schema is for its target namespace http://www.example.org/Test so it defines an element with name MyElement in that target namespace http://www.example.org/Test. Your instance document however has an element with name MyElement in no namespace. That is why the validating parser tells you it can't find a declaration for that element, you haven't provided a schema for elements in no namespace.

You either need to change the schema to not use a target namespace at all or you need to change the instance to use e.g. <MyElement xmlns="http://www.example.org/Test">A</MyElement>.

In DOS you couldn't use environment variables on the command line, only in batch files, where they used the % sign as a delimiter. If you wanted a literal % sign in a batch file, e.g. in an echo statement, you needed to double it.

This carried over to Windows NT which allowed environment variables on the command line, however for backwards compatibility you still need to double your % signs in a .cmd file.

This is a helpful website listing the mapping for the latest releases of Chrome -

https://www.uitests-chromedrivermapping.com

The problem with merge sort is the merge, if you don't actually need to implement the merge, then it is pretty simple (for a vector of ints):

#include <algorithm>
#include <vector>
using namespace std;

typedef vector<int>::iterator iter;

void mergesort(iter b, iter e) {
    if (e -b > 1) {
        iter m = b + (e -b) / 2;
        mergesort(b, m);
        mergesort(m, e);
        inplace_merge(b, m, e);
    }
}

I found it strangely difficult to locate the python docs for __enter__ and __exit__ methods by Googling, so to help others here is the link:

https://docs.python.org/2/reference/datamodel.html#with-statement-context-managers
https://docs.python.org/3/reference/datamodel.html#with-statement-context-managers
(detail is the same for both versions)

object.__enter__(self)
Enter the runtime context related to this object. The with statement will bind this method’s return value to the target(s) specified in the as clause of the statement, if any.

object.__exit__(self, exc_type, exc_value, traceback)
Exit the runtime context related to this object. The parameters describe the exception that caused the context to be exited. If the context was exited without an exception, all three arguments will be None.

If an exception is supplied, and the method wishes to suppress the exception (i.e., prevent it from being propagated), it should return a true value. Otherwise, the exception will be processed normally upon exit from this method.

Note that __exit__() methods should not reraise the passed-in exception; this is the caller’s responsibility.

I was hoping for a clear description of the __exit__ method arguments. This is lacking but we can deduce them...

Presumably exc_type is the class of the exception.

It says you should not re-raise the passed-in exception. This suggests to us that one of the arguments might be an actual Exception instance ...or maybe you're supposed to instantiate it yourself from the type and value?

We can answer by looking at this article:
http://effbot.org/zone/python-with-statement.htm

For example, the following __exit__ method swallows any TypeError, but lets all other exceptions through:

def __exit__(self, type, value, traceback):
    return isinstance(value, TypeError)

...so clearly value is an Exception instance.

And presumably traceback is a Python traceback object.

I understand that this is fairly old question and has some pretty good answers. But, here is my two cents for the sake of completeness.

As per the official documentation, there are four ways, you can allow complete access for robots to access your site.

Clean:

Specify a global matcher with a disallow segment as mentioned by @unor. So your /robots.txt looks like this.

User-agent: *
Disallow:

The hack:

Create a /robots.txt file with no content in it. Which will default to allow all for all type of Bots.

I don't care way:

Do not create a /robots.txt altogether. Which should yield the exact same results as the above two.

The ugly:

From the robots documentation for meta tags, You can use the following meta tag on all your pages on your site to let the Bots know that these pages are not supposed to be indexed.

<META NAME="ROBOTS" CONTENT="NOINDEX">

In order for this to be applied to your entire site, You will have to add this meta tag for all of your pages. And this tag should strictly be placed under your HEAD tag of the page. More about this meta tag here.

defaultdict is great when the default value is static, like a new list, but not so much if it's dynamic.

For example, I need a dictionary to map strings to unique ints. defaultdict(int) will always use 0 for the default value. Likewise, defaultdict(intGen()) always produces 1.

Instead, I used a regular dict:

nextID = intGen()
myDict = {}
for lots of complicated stuff:
    #stuff that generates unpredictable, possibly already seen str
    strID = myDict.setdefault(myStr, nextID())

Note that dict.get(key, nextID()) is insufficient because I need to be able to refer to these values later as well.

intGen is a tiny class I build that automatically increments an int and returns its value:

class intGen:
    def __init__(self):
        self.i = 0

    def __call__(self):
        self.i += 1
    return self.i

If someone has a way to do this with defaultdict I'd love to see it.

Save the count as you go - and use validation to enforce it. I hacked this together - for keeping a count of unique votes and counts which keeps coming up!. But this time I have tested my suggestion! (notwithstanding cut/paste errors!).

The 'trick' here is to use the node priority to as the vote count...

The data is:

vote/$issueBeingVotedOn/user/$uniqueIdOfVoter = thisVotesCount, priority=thisVotesCount vote/$issueBeingVotedOn/count = 'user/'+$idOfLastVoter, priority=CountofLastVote

,"vote": {
  ".read" : true
  ,".write" : true
  ,"$issue" : {
    "user" : {
      "$user" : {
        ".validate" : "!data.exists() && 
             newData.val()==data.parent().parent().child('count').getPriority()+1 &&
             newData.val()==newData.GetPriority()" 

user can only vote once && count must be one higher than current count && data value must be same as priority.

      }
    }
    ,"count" : {
      ".validate" : "data.parent().child(newData.val()).val()==newData.getPriority() &&
             newData.getPriority()==data.getPriority()+1 "
    }

count (last voter really) - vote must exist and its count equal newcount, && newcount (priority) can only go up by one.

  }
}

Test script to add 10 votes by different users (for this example, id's faked, should user auth.uid in production). Count down by (i--) 10 to see validation fail.

<script src='https://cdn.firebase.com/v0/firebase.js'></script>
<script>
  window.fb = new Firebase('https:...vote/iss1/');
  window.fb.child('count').once('value', function (dss) {
    votes = dss.getPriority();
    for (var i=1;i<10;i++) vote(dss,i+votes);
  } );

function vote(dss,count)
{
  var user='user/zz' + count; // replace with auth.id or whatever
  window.fb.child(user).setWithPriority(count,count);
  window.fb.child('count').setWithPriority(user,count);
}
</script>

The 'risk' here is that a vote is cast, but the count not updated (haking or script failure). This is why the votes have a unique 'priority' - the script should really start by ensuring that there is no vote with priority higher than the current count, if there is it should complete that transaction before doing its own - get your clients to clean up for you :)

The count needs to be initialised with a priority before you start - forge doesn't let you do this, so a stub script is needed (before the validation is active!).

You may want to take if from a diffrent side: It seems easier to have a TextView with a drawable on the background:

 <TextView
            android:id="@+id/text"
            android:background="@drawable/rounded_rectangle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
        </TextView>

Mime type option is not best option for validating CSV file. I used this code this worked well in all browser

$type = explode(".",$_FILES['file']['name']);
if(strtolower(end($type)) == 'csv'){

}
else
{

}

The most upvoted solution generally works but for Spring and/or Spring Boot, the values will not wire to parameters in controller methods annotated with @RequestParam unless you specifically implemented getParameterValues(). I combined the solution(s) here and from this blog:

import java.util.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;

public class MutableHttpRequest extends HttpServletRequestWrapper {

    private final Map<String, String[]> mutableParams = new HashMap<>();

    public MutableHttpRequest(final HttpServletRequest request) {
        super(request);
    }

    public MutableHttpRequest addParameter(String name, String value) {
        if (value != null)
            mutableParams.put(name, new String[] { value });

        return this;
    }

    @Override
    public String getParameter(final String name) {
        String[] values = getParameterMap().get(name);

        return Arrays.stream(values)
                .findFirst()
                .orElse(super.getParameter(name));
    }

    @Override
    public Map<String, String[]> getParameterMap() {
        Map<String, String[]> allParameters = new HashMap<>();
        allParameters.putAll(super.getParameterMap());
        allParameters.putAll(mutableParams);

        return Collections.unmodifiableMap(allParameters);
    }

    @Override
    public Enumeration<String> getParameterNames() {
        return Collections.enumeration(getParameterMap().keySet());
    }

    @Override
    public String[] getParameterValues(final String name) {
        return getParameterMap().get(name);
    }
}

note that this code is not super-optimized but it works.

You are missing two closing parentheses...and I am not sure an ampersand works as a string concatenation operator. Try '+'

SELECT dbo.COL_V_Cost_GEMS_Detail.TNG_SYS_NR AS [EHP Code], 
dbo.COL_TBL_VCOURSE.TNG_NA AS [Course Title], 
LTRIM(RTRIM(FCT_TYP_CD)) + ') AND (' + LTRIM(RTRIM(DEP_TYP_ID)) + ')' AS [Course Owner]

try:

$("td[id^=" + value + "]")

I had the same problem, by accident mistake. I'll share it here, in case someone may have made the same mistake.

Basic steps, as others described.

1. Download putty and puttygen, or the putty package and install it.
2. Get the .pem file from your AWS EC2 instance.
3. Use puttygen to convert the .pem file so that you'll have a private key --- mistake happened here. I chose "Conversions" tab from PuttyGen, and load my .pem file. After loading pem file, here DO NOT hit "Generate", instead directly "Save private key". That's the key you need. If you click Generate, you'll have a totally different pair of keys.
4. In putty, use [email protected], and load the private key at SSH/Auth

Good luck!

You're setting it to not be able to scale (maximum-scale = initial-scale), so it can't scale up when you rotate to landscape mode. Set maximum-scale=1.6 and it will scale properly to fit landscape mode.

var dt = new Date();
    var h =  dt.getHours(), m = dt.getMinutes();
    var thistime = (h > 12) ? (h-12 + ':' + m +' PM') : (h + ':' + m +' AM');
console.log(thistime);

Here is the Demo

You are using the wrong iteration counter, replace inp.charAt(i) with inp.charAt(j).

Cardinality refers to the uniqueness of data contained in a column. If a column has a lot of duplicate data (e.g. a column that stores either "true" or "false"), it has low cardinality, but if the values are highly unique (e.g. Social Security numbers), it has high cardinality.

There's no casting in javascript, so you cannot throw if "casting fails".
Typescript supports casting but that's only for compilation time, and you can do it like this:

const toDo = <IToDoDto> req.body;
// or
const toDo = req.body as IToDoDto;

You can check at runtime if the value is valid and if not throw an error, i.e.:

function isToDoDto(obj: any): obj is IToDoDto {
    return typeof obj.description === "string" && typeof obj.status === "boolean";
}

@Post()
addToDo(@Response() res, @Request() req) {
    if (!isToDoDto(req.body)) {
        throw new Error("invalid request");
    }

    const toDo = req.body as IToDoDto;
    this.toDoService.addToDo(toDo);
    return res.status(HttpStatus.CREATED).end();
}

Edit

As @huyz pointed out, there's no need for the type assertion because isToDoDto is a type guard, so this should be enough:

if (!isToDoDto(req.body)) {
    throw new Error("invalid request");
}

this.toDoService.addToDo(req.body);

In c++ you can use following function, it will return the size of you file in bytes.

#include <fstream>

int fileSize(const char *add){
    ifstream mySource;
    mySource.open(add, ios_base::binary);
    mySource.seekg(0,ios_base::end);
    int size = mySource.tellg();
    mySource.close();
    return size;
}

SELECT * FROM tablename WHERE visible=1 ORDER BY CASE WHEN `position` = 0 THEN 'a' END , position ASC

Place your springbootapplication class in root package for example if your service,controller is in springBoot.xyz package then your main class should be in springBoot package otherwise it will not scan below packages

Destination Selection in Installer

If domain (a.k.a destination) selection is desired between user domain and system domain then rather than trying <domains enable_anywhere="true"> use following:

<domains enable_currentUserHome="true" enable_localSystem="true"/>

enable_currentUserHome installs application app under ~/Applications/ and enable_localSystem allows the application to be installed under /Application

I've tried this in El Capitan 10.11.6 (15G1217) and it seems to be working perfectly fine in 1 dev machine and 2 different VMs I tried.

use Regex.Split(string,"#|#");

You can use something like

SET @cnt = (SELECT COUNT(*) FROM User)

or

SELECT @cnt = (COUNT(*) FROM User)

For this to work the SELECT must return a single column and a single result and the SELECT statement must be in parenthesis.

Edit: Have you tried something like this?

DECLARE @OOdate DATETIME

SET @OOdate = Select OO.Date from OLAP.OutageHours as OO where OO.OutageID = 1

Select COUNT(FF.HALID) 
from Outages.FaultsInOutages as OFIO 
inner join Faults.Faults as FF 
    ON FF.HALID = OFIO.HALID 
WHERE @OODate = FF.FaultDate
    AND OFIO.OutageID = 1

select * from employee_list order by salary desc limit 2;

You are mixing the deprecated mysql extension with mysqli.

Try something like:

$sql = mysqli_query($success, "SELECT * FROM login WHERE username = '".$_POST['username']."' and password = '".md5($_POST['password'])."'");
$row = mysqli_num_rows($sql);

On properties,

Check whether radio button is selected for

Run only when user is logged on 

If you selected for the above option then that is the reason why it is failed.

so change the option to

Run whether user is logged on or not

OR

In other case, user might have changed his/her login credentials

See following snippet :

$(document).on("click", "a.deleteText", function() {_x000D_
    if (confirm('Are you sure ?')) {_x000D_
        $(this).prev('span.text').remove();_x000D_
    }_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<div class="container">_x000D_
    <span class="text">some text</span>_x000D_
    <a href="#" class="deleteText"><span class="delete-icon"> x Delete </span></a>_x000D_
</div>

Your class MyClass creates a new MyClassToBeTested, instead of using your mock. My article on the Mockito wiki describes two ways of dealing with this.

Use a service to achieve this:

MyApp.app.service("xxxSvc", function () {

var _xxx = {};

return {
    getXxx: function () {
        return _xxx;
    },
    setXxx: function (value) {
        _xxx = value;
    }
};

});

Next, inject this service into both controllers.

In Controller1, you would need to set the shared xxx value with a call to the service: xxxSvc.setXxx(xxx)

Finally, in Controller2, add a $watch on this service's getXxx() function like so:

  $scope.$watch(function () { return xxxSvc.getXxx(); }, function (newValue, oldValue) {
        if (newValue != null) {
            //update Controller2's xxx value
            $scope.xxx= newValue;
        }
    }, true);

You can use [ModSecurity][1] to view POST data.

Install on Debian/Ubuntu:

$ sudo apt install libapache2-mod-security2

Use the recommended configuration file:

$ sudo mv /etc/modsecurity/modsecurity.conf-recommended /etc/modsecurity/modsecurity.conf

Reload Apache:

$ sudo service apache2 reload

You will now find your data logged under /var/log/apache2/modsec_audit.log

$ tail -f /var/log/apache2/modsec_audit.log

In SQL Server Import and Export Wizard you can adjust the source data types in the Advanced tab (these become the data types of the output if creating a new table, but otherwise are just used for handling the source data).

The data types are annoyingly different than those in MS SQL, instead of VARCHAR(255) it's DT_STR and the output column width can be set to 255. For VARCHAR(MAX) it's DT_TEXT.

So, on the Data Source selection, in the Advanced tab, change the data type of any offending columns from DT_STR to DT_TEXT (You can select multiple columns and change them all at once).

if ($u = User::where('email', '=', $value)->first())
{
   // do something with $u
   return 'exists';
} else {
  return 'nope';
}

would work with try/catch

->get() would still return an empty array

There is a big difference. Tasks are scheduled on the ThreadPool and could even be executed synchronous if appropiate.

If you have a long running background work you should specify this by using the correct Task Option.

You should prefer Task Parallel Library over explicit thread handling, as it is more optimized. Also you have more features like Continuation.

Unfortunately (depending on your version and release of Python) some types of objects use "free lists" which are a neat local optimization but may cause memory fragmentation, specifically by making more and more memory "earmarked" for only objects of a certain type and thereby unavailable to the "general fund".

The only really reliable way to ensure that a large but temporary use of memory DOES return all resources to the system when it's done, is to have that use happen in a subprocess, which does the memory-hungry work then terminates. Under such conditions, the operating system WILL do its job, and gladly recycle all the resources the subprocess may have gobbled up. Fortunately, the multiprocessing module makes this kind of operation (which used to be rather a pain) not too bad in modern versions of Python.

In your use case, it seems that the best way for the subprocesses to accumulate some results and yet ensure those results are available to the main process is to use semi-temporary files (by semi-temporary I mean, NOT the kind of files that automatically go away when closed, just ordinary files that you explicitly delete when you're all done with them).

Dynamic variables creation

Pros

• Works for >9 arguments
• Keeps %1, %2, ... %* in tact
• Works for both /arg and -arg style
• No prior knowledge about arguments
• Implementation is separate from main routine

Cons

• Old arguments may leak into consecutive runs, therefore use setlocal for local scoping or write an accompanying :CLEAR-ARGS routine!
• No alias support yet (like --force to -f)
• No empty "" argument support

Usage

Here is an example how the following arguments relate to .bat variables:

>> testargs.bat /b 3 -c /d /e /f /g /h /i /j /k /bar 5 /foo "c:\"

echo %*        | /b 3 -c /d /e /f /g /h /i /j /k /bar 5 /foo "c:\"
echo %ARG_FOO% | c:\
echo %ARG_A%   |
echo %ARG_B%   | 3
echo %ARG_C%   | 1
echo %ARG_D%   | 1

Implementation

@echo off
setlocal

CALL :ARG-PARSER %*

::Print examples
echo: ALL: %*
echo: FOO: %ARG_FOO%
echo: A:   %ARG_A%
echo: B:   %ARG_B%

Flushing seemingly failing to work is a side effect of automatic character set detection.

The browser will not display anything until it knows the character set to display it in, and if you don't specify the character set, it need tries to guess it. The problem being that it can't make a good guess without enough data, which is why browsers seem to have this 1024 byte (or similar) buffer they need filled before displaying anything.

The solution is therefore to make sure the browser doesn't have to guess the character set.

If you're sending text, add a '; charset=utf-8' to its content type, and if it's HTML, add the character set to the appropriate meta tag.

if the variable is a string

bool result = string.IsNullOrEmpty(variableToTest);

if you only have an object which may or may not contain a string then

bool result = string.IsNullOrEmpty(variableToTest as string);

For that you just need write to some lines

   DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
   ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
   drawer.addDrawerListener(toggle);
   toggle.setDrawerIndicatorEnabled(true);
   toggle.syncState();

toggle.setDrawerIndicatorEnabled(true); if this is false make it true or remove this line

You're comparing apples to oranges here:

• webHttpBinding is the REST-style binding, where you basically just hit a URL and get back a truckload of XML or JSON from the web service

• basicHttpBinding and wsHttpBinding are two SOAP-based bindings which is quite different from REST. SOAP has the advantage of having WSDL and XSD to describe the service, its methods, and the data being passed around in great detail (REST doesn't have anything like that - yet). On the other hand, you can't just browse to a wsHttpBinding endpoint with your browser and look at XML - you have to use a SOAP client, e.g. the WcfTestClient or your own app.

So your first decision must be: REST vs. SOAP (or you can expose both types of endpoints from your service - that's possible, too).

Then, between basicHttpBinding and wsHttpBinding, there differences are as follows:

• basicHttpBinding is the very basic binding - SOAP 1.1, not much in terms of security, not much else in terms of features - but compatible to just about any SOAP client out there --> great for interoperability, weak on features and security

• wsHttpBinding is the full-blown binding, which supports a ton of WS-* features and standards - it has lots more security features, you can use sessionful connections, you can use reliable messaging, you can use transactional control - just a lot more stuff, but wsHttpBinding is also a lot *heavier" and adds a lot of overhead to your messages as they travel across the network

For an in-depth comparison (including a table and code examples) between the two check out this codeproject article: Differences between BasicHttpBinding and WsHttpBinding

For single value the datetime.strptime method is the fastest

import arrow
from datetime import datetime
import pandas as pd

l = ['24052010']

%timeit _ = list(map(lambda x: datetime.strptime(x, '%d%m%Y').date(), l))
6.86 µs ± 56.5 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)

%timeit _ = list(map(lambda x: x.date(), pd.to_datetime(l, format='%d%m%Y')))
305 µs ± 6.32 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

%timeit _ = list(map(lambda x: arrow.get(x, 'DMYYYY').date(), l))
46 µs ± 978 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)

For a list of values the pandas pd.to_datetime is the fastest

l = ['24052010'] * 1000

%timeit _ = list(map(lambda x: datetime.strptime(x, '%d%m%Y').date(), l))
6.32 ms ± 89.6 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

%timeit _ = list(map(lambda x: x.date(), pd.to_datetime(l, format='%d%m%Y')))
1.76 ms ± 27.3 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

%timeit _ = list(map(lambda x: arrow.get(x, 'DMYYYY').date(), l))
44.5 ms ± 522 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

For ISO8601 datetime format the ciso8601 is a rocket

import ciso8601

l = ['2010-05-24'] * 1000

%timeit _ = list(map(lambda x: ciso8601.parse_datetime(x).date(), l))
241 µs ± 3.24 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

Maybe I'm not understanding the question but here is my simple solution that works -

# I want to Display total heads bent this machine so I define a label -
TotalHeadsLabel3 = Label(leftFrame)
TotalHeadsLabel3.config(font=Helv12,fg='blue',text="Total heads " + str(TotalHeads))
TotalHeadsLabel3.pack(side=TOP)

# I update the int variable adding the quantity bent -
TotalHeads = TotalHeads + headQtyBent # update ready to write to file & display
TotalHeadsLabel3.config(text="Total Heads "+str(TotalHeads)) # update label with new qty

I agree that labels are not automatically updated but can easily be updated with the

<label name>.config(text="<new text>" + str(<variable name>))

That just needs to be included in your code after the variable is updated.
