Java doesn't normally accept "/" to use in defining a file directory, so try this:

 File file = new File ("C:\\Users\\user\\workspace\\FileTester\\myFile.txt");

If the file doesn't exist do:

 try {
      file.createNewFile();
 }
 catch (IOException e) {
 e.printStackTrace();
 }

• copy the .war file in the webapps folder
• upload the file using the manager application - http://host:port/manager. You will have to setup some users beforehand.
• (not recommended, but working) - manually extract the .war file as a .zip archive and place the extracted files in webapps/webappname

Sometimes administrators configure tomcat so that war files are deployed outside the tomcat folder. Even in that case:

After you have it deployed (check the /logs dir for any problems), it should be accessible via: http://host:port/yourwebappname/. So in your case, one of those:

http://bilgin.ath.cx/TestWebApp/
http://bilgin.ath.cx:8080/TestWebApp/

If you don't manage by doing the above and googling - turn to your support. There might be an alternative port, or there might be something wrong with the application (and therefore in the logs)

Assuming that you only have one pair of parenthesis.

string s = "User name (sales)";
int start = s.IndexOf("(") + 1;
int end = s.IndexOf(")", start);
string result = s.Substring(start, end - start);

How about:

from xx in table
where stringarray.Contains(xx.uid.ToString())
select xx

I would do using String#tr :

"1,112".tr(',','').to_i # => 1112

For Xamarin.iOS you can use the following code to get contents of the file if file exists.

var documents = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
var filename = Path.Combine(documents, "xyz.json");
if (File.Exists(filename))
{
var text =System.IO.File.ReadAllText(filename);
}

We could assert

const inputElement: HTMLInputElement = document.getElementById('greet')

Or with as-syntax

const inputElement = document.getElementById('greet') as HTMLInputElement

Giving

const inputValue = inputElement.value // now inferred to be string

DirectoryInfo Folder = new DirectoryInfo(Server.MapPath(path)); 
if (Folder .Exists)
{
    foreach (FileInfo fl in Folder .GetFiles())
    {
        fl.Delete();
    }

    Folder .Delete();
}

:g/^$/d

:g will execute a command on lines which match a regex. The regex is 'blank line' and the command is :d (delete)

In my case the table was updated correctly, but setNeedDisplay() was not called for the image so I mistakenly thought that the data was not reloaded.

You can use lodashs xor for this

doArraysContainSameElements = _.xor(arr1, arr2).length === 0

If you consider array [1, 1] to be different than array [1] then you may improve performance a bit like so:

doArraysContainSameElements = arr1.length === arr2.length === 0 && _.xor(arr1, arr2).length === 0

This error may also be brought about if the symbolic link is to a dynamic library, .so, but for legacy reasons -static appears among the link flags. If so, try removing it.

Knowing how to write a preset dictionary is useful to know as well:

cmap =  {'US':'USA','GB':'Great Britain'}

# Explicitly:
# -----------
def cxlate(country):
    try:
        ret = cmap[country]
    except KeyError:
        ret = '?'
    return ret

present = 'US' # this one is in the dict
missing = 'RU' # this one is not

print cxlate(present) # == USA
print cxlate(missing) # == ?

# or, much more simply as suggested below:

print cmap.get(present,'?') # == USA
print cmap.get(missing,'?') # == ?

# with country codes, you might prefer to return the original on failure:

print cmap.get(present,present) # == USA
print cmap.get(missing,missing) # == RU

Say you want to access the scope of the element like

<div ng-controller="hw"></div>

You could use the following in the console:

angular.element(document.querySelector('[ng-controller=hw]')).scope();

This will give you the scope at that element.

HTML:

<div class="Settings" id="GTSettings">
  <h3 class="SettingsTitle"><a class="toggle" ><img src="${appThemePath}/images/toggle-collapse-light.gif" alt="" /></a>General Theme Settings</h3>
  <div class="options">
    <table>
      <tr>
        <td>

        </td>
      </tr>
    </table>
  </div>
</div>

JavaScript:

$(document).ready(function() {

  $(".options").hide();
  $(".SettingsTitle").click(function(e) {
    var appThemePath = $("#appThemePath").text();

    var closeMenuImg = appThemePath + '/images/toggle-collapse-light.gif';
    var openMenuImg = appThemePath + '/images/toggle-collapse-dark.gif';

    var elem = $(this).next('.options');
    $('.options').not(elem).hide('fast');
    $('.SettingsTitle').not($(this)).parent().children("h3").children("a.toggle").children("img").attr('src', closeMenuImg);
    elem.toggle('fast');
    var targetImg = $(this).parent().children("h3").children("a.toggle").children("img").attr('src') === closeMenuImg ? openMenuImg : closeMenuImg;
    $(this).parent().children("h3").children("a.toggle").children("img").attr('src', targetImg);
  });

});

I'm not sure how necessary this is, and it adds a call to getElementById, but if you're really keen on getting inline JavaScript out of your code, you can pass it as an HTML attribute, namely:

<span class="metadata" id="metadata-size-of-widget" title="<?php echo json_encode($size_of_widget) ?>"></span>

And then in your JavaScript:

var size_of_widget = document.getElementById("metadata-size-of-widget").title;

I know this is a while ago but I encountered this and followed the other answers here but to no avail, I found the solution via this question (Stackoverflow Question)

Essentially just needed to edit the php.ini file (mine was found at c:\xampp\php\php.ini) and uncomment these lines...

;extension=php_mysql.dll
;extension=php_mysqli.dll
;extension=php_pdo_mysql.dll

After restarting apache all was working as expected.

JavaScript Code

function ctrl($scope){
$scope.call={state:['second','first','nothing','Never', 'Gonna', 'Give', 'You', 'Up']}


$scope.whatClassIsIt= function(someValue){
     if(someValue=="first")
            return "ClassA"
     else if(someValue=="second")
         return "ClassB";
    else
         return "ClassC";
}
}

QRGen is a good library that creates a layer on top of ZXing and makes QR Code generation in Java a piece of cake.

I think it can be simplified into:

grep sysa /etc/passwd || {
    echo "ERROR - The user sysa could not be looked up"
    exit 2
}

or in a single command line

$ grep sysa /etc/passwd || { echo "ERROR - The user sysa could not be looked up"; exit 2; }

Why are you combining GET and POST? Use one or the other.

$.ajax({
    type: 'post',
    data: {
        timestamp: timestamp,
        uid: uid
        ...
    }
});

php:

$uid =$_POST['uid'];

Or, just format your request properly (you're missing the ampersands for the get parameters).

url:"getdata.php?timestamp="+timestamp+"&uid="+id+"&uname="+name,

Based on @jared-burrows' solution. For any package, but passing Context as parameter...

public static String getDataDir(Context context) throws Exception {
    return context.getPackageManager()
            .getPackageInfo(context.getPackageName(), 0)
            .applicationInfo.dataDir;
}

This worked for me:

1. Create a new project
2. Create a class in it
3. Add erroneous code, let error come
4. Now go to your project
5. Go to Problems window
6. Double click on a error

It starts showing compilation errors in the code.

You can use in to look for an item in a collection, and a list comprehension to extract the field you are interested in. This (works for lists, sets, tuples, and anything that defines __contains__ or __getitem__).

If the log indicates java.lang.UnsupportedClassVersionError: JVM**** bad major version.

Then the code and server is not compiled with the same JDK version.

To fix this, please switch the JDK version either in code or server JDK.

Try this:- In the below use case, im switching to 1.7_64 (JDK 1.7 64 bit)

c:\IBM\WebSphere\WSRR\v8.5\bin\managesdk.bat -enableProfile -profileName WSRRSrv01 -sdkname 1.7_64

The built-in process module has a method memoryUsage that offers insight in the memory usage of the current Node.js process. Here is an example from in Node v0.12.2 on a 64-bit system:

$ node --expose-gc
> process.memoryUsage();  // Initial usage
{ rss: 19853312, heapTotal: 9751808, heapUsed: 4535648 }
> gc();                   // Force a GC for the baseline.
undefined
> process.memoryUsage();  // Baseline memory usage.
{ rss: 22269952, heapTotal: 11803648, heapUsed: 4530208 }
> var a = new Array(1e7); // Allocate memory for 10m items in an array
undefined
> process.memoryUsage();  // Memory after allocating so many items
{ rss: 102535168, heapTotal: 91823104, heapUsed: 85246576 }
> a = null;               // Allow the array to be garbage-collected
null
> gc();                   // Force GC (requires node --expose-gc)
undefined
> process.memoryUsage();  // Memory usage after GC
{ rss: 23293952, heapTotal: 11803648, heapUsed: 4528072 }
> process.memoryUsage();  // Memory usage after idling
{ rss: 23293952, heapTotal: 11803648, heapUsed: 4753376 }

In this simple example, you can see that allocating an array of 10M elements consumers approximately 80MB (take a look at heapUsed).
If you look at V8's source code (Array::New, Heap::AllocateRawFixedArray, FixedArray::SizeFor), then you'll see that the memory used by an array is a fixed value plus the length multiplied by the size of a pointer. The latter is 8 bytes on a 64-bit system, which confirms that observed memory difference of 8 x 10 = 80MB makes sense.

spent some time trying to import modules from a list, and this is the thread that got me most of the way there - but I didnt grasp the use of ___import____ -

so here's how to import a module from a string, and get the same behavior as just import. And try/except the error case, too. :)

  pipmodules = ['pycurl', 'ansible', 'bad_module_no_beer']
  for module in pipmodules:
      try:
          # because we want to import using a variable, do it this way
          module_obj = __import__(module)
          # create a global object containging our module
          globals()[module] = module_obj
      except ImportError:
          sys.stderr.write("ERROR: missing python module: " + module + "\n")
          sys.exit(1)

and yes, for python 2.7> you have other options - but for 2.6<, this works.

To save a bit time:

1) You can mark your app icon images all in finder and drag them into your Assets catalog all at once by dragging into one of the empty slots of the app icon imageset. When you hold your drag over the slot, several of the other slots look selected and when you drop those all will be filled up at once. Note that this works in XCode 8 (I haven't tried XCode 7), but in XCode 9 beta not yet.

2) The "Technical Q&A QA1686" apple documentation site has the sizes per app icon slot already calculated for you in a nice image and also contains the correct image names conventions.

You need to call self.a() to invoke a from b. a is not a global function, it is a method on the class.

You may want to read through the Python tutorial on classes some more to get the finer details down.

For python3 where -1 indicate the value that to be decremented in each step for n in range(6,0,-1): print(n)

I think df['word'].value_counts() should serve. By skipping the groupby machinery, you'll save some time. I'm not sure why count should be much slower than max. Both take some time to avoid missing values. (Compare with size.)

In any case, value_counts has been specifically optimized to handle object type, like your words, so I doubt you'll do much better than that.

Its important to mention that once in 4-5 years this method might give a 1 second error, becase of a leap-second (http://www.nist.gov/pml/div688/leapseconds.cfm), and the correct formula for that day would be

(24*60*60 + 1) * 1000

There is a question Are leap seconds catered for by Calendar? and the answer is no.

So, if You're designing super time-dependant software, be careful about this formula.

var datep = $('#datepicker').val();

if(Date.parse(datep)-Date.parse(new Date())<0)
{
   // do something
}

If you look at the alternatives on this page, of course the first option looks better and the second one is just more verbose. But if you are looking through a large class that someone else wrote, that verbosity can make the difference between realizing right away what the conditional is testing or not.

One of the reasons I moved away from Perl is because it relies so heavily on punctuation, which is much slower to interpret while reading.

I know I'm outvoted here, but I will almost always side with more explicit code so others can read it more accurately. Then again, I would never use a boolean variable called "status" either. Maybe isSuccess or just success, but "status" being true or false does not mean anything to the casual reader intuitively. As you can tell, I'm very into code readability because I read so much code others have written.

Just look at the python GUI programming options at http://wiki.python.org/moin/GuiProgramming. But, Consider Wxpython for your GUI application as it is cross platform. And,from above link you could also get some IDE to work upon.

Click on the Monitor (DDMS Included) button on the toolbar -- it looks like the Android bugdroid:

That will bring up the DDMS window. Select the emulator instance from the Devices tab on the left, and click on the camera button in the toolbar above it, next to the stop sign icon:

Note that if your emulator is running Android 4.4 or I think 4.3, then screen capture functionality is broken -- you'll have to use a physical device to get screenshots on those OS versions. It works okay for Android prior to 4.3. That bug is https://code.google.com/p/android/issues/detail?id=62284

This property:

marshaller.setProperty("com.sun.xml.bind.xmlDeclaration", false);

However, I wouldn't consider this best practice.

This error happens because of your Jre version of Eclipse and Tomcat are mismatched ..either change eclipse one to tomcat one or ViceVersa..

Both should be same ..Java version mismatched ..Check it

MSalters solution is a good one but basically re-implements boost::assign::map_list_of. If you have boost, you can use it directly:

#include <boost/assign/list_of.hpp>
#include <boost/unordered_map.hpp>
#include <iostream>

using boost::assign::map_list_of;

enum eee { AA,BB,CC };

const boost::unordered_map<eee,const char*> eeeToString = map_list_of
    (AA, "AA")
    (BB, "BB")
    (CC, "CC");

int main()
{
    std::cout << " enum AA = " << eeeToString.at(AA) << std::endl;
    return 0;
}

Use following formula:

=CONCATENATE(LOWER(MID(A1,1,1)),LOWER( B1))

for

Josh Smith = jsmith

note that A1 contains name and B1 contains surname

import sys
sys.path.append("path/to/Modules")
print sys.path

This won't persist over reboots or get translated to other files. It is however great if you don't want to make a permanent modification to your system.

The usual rule for casting to a bool is that a few special literals (False, 0, 0.0, (), [], {}) are false and then everything else is true, so I recommend the following:

def boolify(val):
    if (isinstance(val, basestring) and bool(val)):
        return not val in ('False', '0', '0.0')
    else:
        return bool(val)

I think you are saying that you have python2 and python3 installed and have added a reference to each version under Pycharm > Settings > Project Interpreter

What I think you are asking is how do you have some projects run with Python 2 and some projects running with Python 3.

If so, you can look under Run > Edit Configurations

1. Open the design table tab
2. Highlight your two INT fields (Ctrl/Shift+click on the grey blocks in the very first column)
3. Right click -> Set primary key

Create a new sub with the following code and assign it to your button. Change the "DeleteProcess" to the name of your code to do the deletion. This will pop up a box with OK or Cancel and will call your delete sub if you hit ok and not if you hit cancel.

Sub AreYouSure()

Dim Sure As Integer

Sure = MsgBox("Are you sure?", vbOKCancel)
If Sure = 1 Then Call DeleteProcess

End Sub

I too was facing the same issue. Both the answers (the most upvoted one and the accepted one) just give a temporary fix for the same.

Moreover, the config set stop-writes-on-bgsave-error no is a horrible way to over look this error, since what this option does is stop redis from notifying that writes have been stopped and to move on without writing the data in a snapshot. This is simply ignoring this error. Refer this

As for setting dir in config in redis-cli, once you restart the redis service, this shall get cleared too and the same error shall pop up again. The default value of dir in redis.conf is ./ , and if you start redis as root user, then ./ is / to which write permissions aren't granted, and hence the error.

The best way is to set the dir parameter in redis.conf file and set proper permissions to that directory. Most of the debian distributions shall have it in /etc/redis/redis.conf

You can like:

window.open('url', 'window name', 'window settings')

jQuery:

$('a#link_id').click(function(){
  window.open('url', 'window name', 'window settings');
  return false;
});

You could also set the target to _blank actually.

This creates another array without those columns:

  b = a.compress(logical_not(z), axis=1)

A nested object (child) inside another object (parent) cannot get data directly from its parent.

Have a look on this:

var main = {
    name : "main object",
    child : {
        name : "child object"
    }
};

If you ask the main object what its child name is (main.child.name) you will get it.
Instead you cannot do it vice versa because the child doesn't know who its parent is.
(You can get main.name but you won't get main.child.parent.name).

By the way, a function could be useful to solve this clue.
Let's extend the code above:

var main = {
    name : "main object",
    child : {
        name : "child object"
    },
    init : function() {
        this.child.parent = this;
        delete this.init;
        return this;
    }
}.init();

Inside the init function you can get the parent object simply calling this.
So we define the parent property directly inside the child object.
Then (optionally) we can remove the init method.
Finally we give the main object back as output from the init function.

If you try to get main.child.parent.name now you will get it right.
It is a little bit tricky but it works fine.

Here is a simple example using #ref to scroll to the bottom of a div.

/*_x000D_
Defined somewhere:_x000D_
  var vueContent = new Vue({_x000D_
      el: '#vue-content',_x000D_
      ..._x000D_
 */_x000D_
_x000D_
var messageDisplay = vueContent.$refs.messageDisplay;_x000D_
messageDisplay.scrollTop = messageDisplay.scrollHeight;

<div id='vue-content'>_x000D_
  <div ref='messageDisplay' id='messages'>_x000D_
    <div v-for="message in messages">_x000D_
      {{ message }}_x000D_
    </div>_x000D_
  </div>_x000D_
</div>

Notice that by putting ref='messageDisplay' in the HTML, you have access to the element through vueContent.$refs.messageDisplay

Live Demo

grid is not a global, it is local to the main function. Change this:

int nonrecursivecountcells(color[ROW_SIZE][COL_SIZE], int row, int column)

to this:

int nonrecursivecountcells(color grid[ROW_SIZE][COL_SIZE], int row, int column)

Basically you forgot to give that first param a name, grid will do since it matches your code.

After reviewing MySQL 5.7 changes, MySql stopped supporting zero values in date / datetime.

It's incorrect to use zeros in date or in datetime, just put null instead of zeros.

Intent service is child of Service

IntentService: If you want to download a bunch of images at the start of opening your app. It's a one-time process and can clean itself up once everything is downloaded.

Service: A Service which will constantly be used to communicate between your app and back-end with web API calls. Even if it is finished with its current task, you still want it to be around a few minutes later, for more communication

  private class AsyncTaskRunner extends AsyncTask<String, String, String> {

Call asynctask like:

 AsyncTaskRunner asyncTaskRunner = new AsyncTaskRunner(uploadsModel.getImages());
        asyncTaskRunner.execute();

All these answers are correct, but I had to also check if the string contains other characters and Hebrew letters so I simply used:

if (!str.match(/^[\d]+$/)) {
    //contains other characters as well
}

to change the focus make the textView in xml focusable

<TextView
            **android:focusable="true"**
            android:id="@+id/tv_id"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>

and in java in on create

textView.requestFocus();

or simply hide the keyboard

public void hideKeyBoard(Activity act) {
    act.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
    InputMethodManager imm = (InputMethodManager) act.getSystemService(Context.INPUT_METHOD_SERVICE);
}

A lot answers here recommends $@ or $* with and without quotes, however none seems to explain what these really do and why you should that way. So let me steal this excellent summary from this answer:

| Syntax |      Effective result     |
+--------+---------------------------+
|   $*   |     $1 $2 $3 ... ${N}     |
+--------+---------------------------+
|   $@   |     $1 $2 $3 ... ${N}     |
+--------+---------------------------+
|  "$*"  |    "$1c$2c$3c...c${N}"    |
+--------+---------------------------+
|  "$@"  | "$1" "$2" "$3" ... "${N}" |
+--------+---------------------------+

Notice that quotes makes all the difference and without them both have identical behavior.

For my purpose, I needed to pass parameters from one script to another as-is and for that the best option is:

# file: parent.sh
# we have some params passed to parent.sh 
# which we will like to pass on to child.sh as-is

./child.sh $*

Notice no quotes and $@ should work as well in above situation.

I am not sure does it suit you but I noticed that tar does not fail on changed/deleted files in pipe mode. See what I mean.

Test script:

#!/usr/bin/env bash
set -ex
tar cpf - ./files | aws s3 cp - s3://my-bucket/files.tar
echo $?

Deleting random files manually...

Output:

+ aws s3 cp - s3://my-bucket/files.tar
+ tar cpf - ./files
tar: ./files/default_images: File removed before we read it
tar: ./files: file changed as we read it
+ echo 0
0

val.ToString("".PadLeft(length, '0'))

Min-value will always start at zero and its nothing you can do about it. But you can change its value when user start scrolling it around.

Here I set the max-value as 64. This calculations are simple: I want the user to pick a time from 15min to 16 hours, and he picks one of every 15min to 16 hours, clear? I know, very simple :)

    SeekBar seekBar = (SeekBar) dialog.findViewById(R.id.seekBar);
    seekBar.setMax(64);

    seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
        float b;

        @Override
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
            float des = (float) progress / 4;
            b = des;
            hours.setText(des + " hours");
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {


        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
            hoursSelected = b;
        }
    });

The best way to do this is with boolean masking:

UPDATE: Now that pandas 0.13 is out, another way to do this is df.query('line_race != 0').

Try this:

Dim dataView As New DataView(table)
dataView.Sort = " AutoID DESC, Name DESC"
Dim dataTable AS DataTable = dataView.ToTable()

Your query is nearly correct. The T-SQL for this is:

UPDATE  Table1
SET     Field1 = Table2.Field1,
        Field2 = Table2.Field2,
        other columns...
FROM    Table2
WHERE   Table1.ID = Table2.ID

In my opinion using a BroadcastReceiver is a cleaner way to cancel a Notification:

In AndroidManifest.xml:

<receiver 
    android:name=.NotificationCancelReceiver" >
    <intent-filter android:priority="999" >
         <action android:name="com.example.cancel" />
    </intent-filter>
</receiver>

In java File:

Intent cancel = new Intent("com.example.cancel");
PendingIntent cancelP = PendingIntent.getBroadcast(context, 0, cancel, PendingIntent.FLAG_CANCEL_CURRENT);

NotificationCompat.Action actions[] = new NotificationCompat.Action[1];

NotificationCancelReceiver

public class NotificationCancelReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        //Cancel your ongoing Notification
    };
}

You can use try-catch block to check for integer value

for eg:

User inputs in form of string

try
{
   int num=Integer.parseInt("Some String Input");
}
catch(NumberFormatException e)
{
  //If number is not integer,you wil get exception and exception message will be printed
  System.out.println(e.getMessage());
}

You're not including the standard <string> header.

You got [un]lucky that some of its pertinent definitions were accidentally made available by the other standard headers that you did include ... but operator<< was not.

Try to set the element's value using the executeScript method of JavascriptExecutor:

WebDriver driver = new FirefoxDriver();
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("document.getElementById('elementID').setAttribute('value', 'new value for element')");

This may be helpful while searching keys present in nested objects and nested arrays. And this is a generic solution to all cases.

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

public class MyClass
{
    public static Object finalresult = null;
    public static void main(String args[]) throws JSONException
    {
        System.out.println(myfunction(myjsonstring,key));
    }

    public static Object myfunction(JSONObject x,String y) throws JSONException
    {
        JSONArray keys =  x.names();
        for(int i=0;i<keys.length();i++)
        {
            if(finalresult!=null)
            {
                return finalresult;                     //To kill the recursion
            }

            String current_key = keys.get(i).toString();

            if(current_key.equals(y))
            {
                finalresult=x.get(current_key);
                return finalresult;
            }

            if(x.get(current_key).getClass().getName().equals("org.json.JSONObject"))
            {
                myfunction((JSONObject) x.get(current_key),y);
            }
            else if(x.get(current_key).getClass().getName().equals("org.json.JSONArray"))
            {
                for(int j=0;j<((JSONArray) x.get(current_key)).length();j++)
                {
                    if(((JSONArray) x.get(current_key)).get(j).getClass().getName().equals("org.json.JSONObject"))
                    {
                        myfunction((JSONObject)((JSONArray) x.get(current_key)).get(j),y);
                    }
                }
            }
        }
        return null;
    }
}

Possibilities:

1. "key":"value"
2. "key":{Object}
3. "key":[Array]

Logic :

• I check whether the current key and search key are the same, if so I return the value of that key.
• If it is an object, I send the value recursively to the same function.
• If it is an array, I check whether it contains an object, if so I recursively pass the value to the same function.

Most probably the issue of ImagePullBackOff is due to either the image not being present or issue with the pod YAML file.

What I will do is this

kubectl get pod -n $namespace $POD_NAME --export > pod.yaml | kubectl -f apply -

I would also see the pod.yaml to see the why the earlier pod didn't work

One of The Shortest method i found for single value while i was searching for myself, is just passing single string and setting string as model in view like this.

In your Partial calling side

@Html.Partial("ParitalAction", "String data to pass to partial")

And then binding the model with Partial View like this

@model string

and the using its value in Partial View like this

@Model

You can also play with other datatypes like array, int or more complex data types like IDictionary or something else.

Hope it helps,

I style my css in its own file. So I'm not sure how you need to type it in as your are styling inside your html file. But you can use the Img{ position: relative Top: 150px; Left: 40px; } This would move my image up 150px and towards the right 40px. This method makes it so you can move anything you want on your page any where on your page If this is confusing just look on YouTube about position: relative

I also use the same method to move my h1 tag on top of my image.

In my html5 file my image is first and below that I have my h1 tag. Idk if this effects witch will be displayed on top of the other one.

Hope this helps.

It's because val is not null, but contains 'null' as a string.

Try to check with 'null'

if ('null' != val)

For an explanation of when and why this works, see the details below.

private static final String[] IP_HEADER_CANDIDATES = {

            "REMOTE_ADDR"
    };

    public static String getIPFromRequest(HttpServletRequest request) {
        String ip = null;
        if (request == null) {
            if (RequestContextHolder.getRequestAttributes() == null) {
                return null;
            }
            request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
        }

        try {
            ip = InetAddress.getLocalHost().getHostAddress();
        } catch (Exception e) {
            e.printStackTrace();
        }
        if (!StringUtils.isEmpty(ip))
            return ip;

        for (String header : IP_HEADER_CANDIDATES) {
            String ipList = request.getHeader(header);
            if (ipList != null && ipList.length() != 0 && !"unknown".equalsIgnoreCase(ipList)) {
                return ipList.split(",")[0];
            }
        }

        return request.getRemoteAddr();
    }

I combie the code above to this code work for most case. Pass the HttpServletRequest request you get from the api to the method

Given an instance of the struct, you set the values.

    student thisStudent;
    Console.WriteLine("Please enter StudentId, StudentName, CourseName, Date-Of-Birth");
    thisStudent.s_id = int.Parse(Console.ReadLine());
    thisStudent.s_name = Console.ReadLine();
    thisStudent.c_name = Console.ReadLine();
    thisStudent.s_dob = Console.ReadLine();

Note this code is incredibly fragile, since we aren't checking the input from the user at all. And you aren't clear to the user that you expect each data point to be entered on a separate line.

dir /s *foo* searches in current folder and sub folders.

It finds directories as well as files.

where /s means(documentation):

/s Lists every occurrence of the specified file name within the specified directory and all subdirectories.

I think this way helps you...

var name=[];
var age=[];
name.push('sulfikar');
age.push('24');
var ent={};
for(var i=0;i<name.length;i++)
{
ent.name=name[i];
ent.age=age[i];
}
JSON.Stringify(ent);

You are looking for the DateTime.Parse() method (MSDN Article)

So you can do:

var dateTime = DateTime.Parse("01/01/2001");

Which will give you a DateTime typed object.

If you need to specify which date format you want to use, you would use DateTime.ParseExact (MSDN Article)

Which you would use in a situation like this (Where you are using a British style date format):

string[] formats= { "dd/MM/yyyy" }
var dateTime = DateTime.ParseExact("01/01/2001", formats, new CultureInfo("en-US"), DateTimeStyles.None);

You should use re.MatchObject.group(0). Like

imtag = re.match(r'<img.*?>', line).group(0)

Edit:

You also might be better off doing something like

imgtag  = re.match(r'<img.*?>',line)
if imtag:
    print("yo it's a {}".format(imgtag.group(0)))

to eliminate all the Nones.

Try this to get type parameters for generic types:

public static string CSharpName(this Type type)
{
    var sb = new StringBuilder();
    var name = type.Name;
    if (!type.IsGenericType) return name;
    sb.Append(name.Substring(0, name.IndexOf('`')));
    sb.Append("<");
    sb.Append(string.Join(", ", type.GetGenericArguments()
                                    .Select(t => t.CSharpName())));
    sb.Append(">");
    return sb.ToString();
}

Maybe not the best solution (due to the recursion), but it works. Outputs look like:

Dictionary<String, Object>

where date_dt = to_date(to_char(sysdate-1, 'YYYY-MM-DD') || ' 19:16:08', 'YYYY-MM-DD HH24:MI:SS') 

should work.

This thread has a good discussion and a useful solution:

function pause( iMilliseconds )
{
    var sDialogScript = 'window.setTimeout( function () { window.close(); }, ' + iMilliseconds + ');';
    window.showModalDialog('javascript:document.writeln ("<script>' + sDialogScript + '<' + '/script>")');
}

Unfortunately it appears that this doesn't work in some versions of IE, but the thread has many other worthy proposals if that proves to be a problem for you.

Solution 1

Context context;
String mess = context.getString(R.string.mess_1)

Solution 2

String mess = getString(R.string.mess_1)

The notation that is used in

a[::-1]

means that for a given string/list/tuple, you can slice the said object using the format

<object_name>[<start_index>, <stop_index>, <step>]

This means that the object is going to slice every "step" index from the given start index, till the stop index (excluding the stop index) and return it to you.

In case the start index or stop index is missing, it takes up the default value as the start index and stop index of the given string/list/tuple. If the step is left blank, then it takes the default value of 1 i.e it goes through each index.

So,

a = '1234'
print a[::2]

would print

13

Now the indexing here and also the step count, support negative numbers. So, if you give a -1 index, it translates to len(a)-1 index. And if you give -x as the step count, then it would step every x'th value from the start index, till the stop index in the reverse direction. For example

a = '1234'
print a[3:0:-1]

This would return

432

Note, that it doesn't return 4321 because, the stop index is not included.

Now in your case,

str(int(a[::-1]))

would just reverse a given integer, that is stored in a string, and then convert it back to a string

i.e "1234" -> "4321" -> 4321 -> "4321"

If what you are trying to do is just reverse the given string, then simply a[::-1] would work .

Import: import java.util.Scanner;

Define your variables: String name; int age;

Define your scanner: Scanner scan = new Scanner(System.in);

If you want to type:

• Text: name = scan.nextLine();
• Integer: age = scan.nextInt();

Close scanner if no longer needed: scan.close();

find / -exec grep -lR "{test-string}" {} \;

tree /f /a

About

The Windows command tree /f /a produces a tree of the current folder and all files & folders contained within it in ASCII format.

The output can be redirected to a text file using the > parameter.

Method

For Windows 8.1 or Windows 10, follow these steps:

1. Navigate into the folder in file explorer.
2. Press Shift, right-click mouse, and select "Open command window here".
3. Type tree /f /a > tree.txt and press Enter.
4. Open the new tree.txt file in your favourite text editor/viewer.

Note: Windows 7, Vista, XP and earlier users can type cmd in the run command box in the start menu for a command window.

This should be easily resolved by importing headers from Angular:

import { Http, Headers } from "@angular/http";

I just want to notice that the geneated code is offen the same if you use pre/post incrementation where the semantic (of pre/post) doesn't matter.

example:

pre.cpp:

#include <iostream>

int main()
{
  int i = 13;
  i++;
  for (; i < 42; i++)
    {
      std::cout << i << std::endl;
    }
}

post.cpp:

#include <iostream>

int main()
{

  int i = 13;
  ++i;
  for (; i < 42; ++i)
    {
      std::cout << i << std::endl;
    }
}

_

$> g++ -S pre.cpp
$> g++ -S post.cpp
$> diff pre.s post.s   
1c1
<   .file   "pre.cpp"
---
>   .file   "post.cpp"

Try use absolute path:

If both of your servers are using WHM, I think we can reduce the time to nil. Create your domain in the new server and set everything ready. Go to the previous server and delete the account corresponding to that domain. Until now I have got no errors by doing this and felt the update instantaneous. FYI I used hostgator hosting (both dedicated servers). And I really dont know why it is so. It's supposed to be not like that until the TTL is over.

For anyone looking at this answer in future, HTML5 implements a new attribute for form elements, hidden, which will automatically apply display:none to your element.

e.g.

<input type="submit" hidden />

Using Xcode 8, "Update project to recommended settings" option turned ON 'No Common Blocks' for my project.

Turning it back to OFF fixed everything up.

some resources:

1. ELF for the ARM architecture
   http://infocenter.arm.com/help/topic/com.arm.doc.ihi0044d/IHI0044D_aaelf.pdf
2. ELF from wiki
   http://en.wikipedia.org/wiki/Executable_and_Linkable_Format

ELF format is generally the default output of compiling. if you use GNU tool chains, you can translate it to binary format by using objcopy, such as:

  arm-elf-objcopy -O binary [elf-input-file] [binary-output-file]

or using fromELF utility(built in most IDEs such as ADS though):

 fromelf -bin -o [binary-output-file] [elf-input-file]

You could do this:

int x = 0x12345678;

x = ( x >> 24 ) | (( x << 8) & 0x00ff0000 )| ((x >> 8) & 0x0000ff00) | ( x << 24)  ; 

printf("value = %x", x);  // x will be printed as 0x78563412

The Z stands for 'Zulu' - your times are in UTC. From Wikipedia:

The UTC time zone is sometimes denoted by the letter Z—a reference to the equivalent nautical time zone (GMT), which has been denoted by a Z since about 1950. The letter also refers to the "zone description" of zero hours, which has been used since 1920 (see time zone history). Since the NATO phonetic alphabet and amateur radio word for Z is "Zulu", UTC is sometimes known as Zulu time. This is especially true in aviation, where Zulu is the universal standard.

You should create the response using Request.CreateResponse:

HttpResponseMessage response =  Request.CreateResponse(HttpStatusCode.BadRequest, "Error message");

You can pass objects not just strings to CreateResponse and it will serialize them based on the request's Accept header. This saves you from manually choosing a formatter.

There are two options. The first (and better) one is using the Fetch as Google option in Webmaster Tools that Mike Flynn commented about. Here are detailed instructions:

1. Go to: https://www.google.com/webmasters/tools/ and log in
2. If you haven't already, add and verify the site with the "Add a Site" button
3. Click on the site name for the one you want to manage
4. Click Crawl -> Fetch as Google
5. Optional: if you want to do a specific page only, type in the URL
6. Click Fetch
7. Click Submit to Index
8. Select either "URL" or "URL and its direct links"
9. Click OK and you're done.

With the option above, as long as every page can be reached from some link on the initial page or a page that it links to, Google should recrawl the whole thing. If you want to explicitly tell it a list of pages to crawl on the domain, you can follow the directions to submit a sitemap.

Your second (and generally slower) option is, as seanbreeden pointed out, submitting here: http://www.google.com/addurl/

Update 2019:

1. Login to - Google Search Console
2. Add a site and verify it with the available methods.
3. After verification from the console, click on URL Inspection.
4. In the Search bar on top, enter your website URL or custom URLs for inspection and enter.
5. After Inspection, it'll show an option to Request Indexing
6. Click on it and GoogleBot will add your website in a Queue for crawling.

Delete the primary key of a table if it exists:

 ALTER TABLE `tableName` DROP PRIMARY KEY;

Adding an auto-increment column to a table :

ALTER TABLE `tableName` ADD `Column_name` INT PRIMARY KEY AUTO_INCREMENT;

Modify the column which we want to consider as the primary key:

alter table `tableName` modify column `Column_name` INT NOT NULL AUTO_INCREMENT PRIMARY KEY;

If you are using C# you should use Environment.NewLine, which accordingly to MSDN it is:

A string containing "\r\n" for non-Unix platforms, or a string containing "\n" for Unix platforms.

It's simple as:

$('#action').val("1");

#action is hidden input field id.

The HttpParams interface isn't there for specifying query string parameters, it's for specifying runtime behaviour of the HttpClient object.

If you want to pass query string parameters, you need to assemble them on the URL yourself, e.g.

new HttpGet(url + "key1=" + value1 + ...);

Remember to encode the values first (using URLEncoder).

foreach is the best way to get array of values.

here the example code: html code:

<form action="send.php" method="post">
    Red<input type="checkbox" name="color[]" id="color" value="red">
    Green<input type="checkbox" name="color[]" id="color" value="green">
    Blue<input type="checkbox" name="color[]" id="color" value="blue">
    Cyan<input type="checkbox" name="color[]" id="color" value="cyan">
    Magenta<input type="checkbox" name="color[]" id="color" value="Magenta">
    Yellow<input type="checkbox" name="color[]" id="color" value="yellow">
    Black<input type="checkbox" name="color[]" id="color" value="black">
    <input type="submit" value="submit">
</form>

phpcode:

<?php

$name = $POST['color'];



foreach ($name as $color){ 
    echo $color."<br />";
}

?>

Here goes:

DECLARE @var nvarchar(max) = 'Man''s best friend';

You will note that the ' is escaped by doubling it to ''.

Since the string delimiter is ' and not ", there is no need to escape ":

DECLARE @var nvarchar(max) = '"My Name is Luca" is a great song';

The second example in the MSDN page on DECLARE shows the correct syntax.

This function check the special chars on key press and eliminates the value if it is not a number

function mobilevalid(id) {

    var feild = document.getElementById(id);

    if (isNaN(feild.value) == false) {
        if (feild.value.length == 1) {
            if (feild.value < 7) {
                feild.value = "";
            }
        } else if (feild.value.length > 10) {
            feild.value = feild.value.substr(0, feild.value.length - 1);
        }
        if (feild.value.charAt(0) < 7) {
            feild.value = "";
        }
    } else {
        feild.value = "";
    }

}

In Eclipse the Ant java.home variable is not based on the Windows JAVA_HOME environment variable. Instead it is set to the home directory of the project's JRE.

To change the default JRE (e.g. change it to a JDK) you can go to Windows->Preferences... and choose Java->Installed JREs.

To change just a single project's JRE you can go to Project->Properties and choose Java Build Path and choose the Libraries tab. Find the JRE System Library and click it, then choose Edit and choose the JRE (or JDK) that you want.

If that doesn't work then when running the build file you can choose Run as->Ant Build... and click the JRE tab, choose separate JRE and specify the JRE you want there.

Serialization is taking a "live" object in memory and converting it to a format that can be stored somewhere (eg. in memory, on disk) and later "deserialized" back into a live object.

How are you converting the submitted names to "a simple .txt list"? During that step, can you instead convert them into a simple HTML list or table? Then you could wrap that in a standard header which includes any styling you want.

Add:

process.env["NODE_TLS_REJECT_UNAUTHORIZED"]

Edit: Not working anymore with new versions of Gmail

This was the only way I found at the time to get it to work with any characters.

doreamon's answer is the correct way to go now, as it works with all characters in new versions of Gmail.

Old answer:

Here is mine. It seems to works on all Android versions, with subject and message body support, and full utf-8 characters support:

public static void email(Context context, String to, String subject, String body) {
    StringBuilder builder = new StringBuilder("mailto:" + Uri.encode(to));
    if (subject != null) {
        builder.append("?subject=" + Uri.encode(Uri.encode(subject)));
        if (body != null) {
            builder.append("&body=" + Uri.encode(Uri.encode(body)));
        }
    }
    String uri = builder.toString();
    Intent intent = new Intent(Intent.ACTION_SENDTO, Uri.parse(uri));
    context.startActivity(intent);
}

It happens when there is no runnable module for Android App in your project. Creating new project definitely solves this.

You can check this using Run > Edit Configurations > Adding Android App. If there is not runnable Android App module then you can't see "AVD Manager" in the menu.

Yes there is:

ARRAY=()
ARRAY+=('foo')
ARRAY+=('bar')

Bash Reference Manual:

In the context where an assignment statement is assigning a value to a shell variable or array index (see Arrays), the ‘+=’ operator can be used to append to or add to the variable's previous value.

It should be noted that an ajax file upload exceeding the client_max_body_size directive for nginx will return this error code.

You could query the table_privileges table in the information schema:

SELECT table_catalog, table_schema, table_name, privilege_type
FROM   information_schema.table_privileges 
WHERE  grantee = 'MY_USER'

You can listen on whatever port you want; generally, user applications should listen to ports 1024 and above (through 65535). The main thing if you have a variable number of listeners is to allocate a range to your app - say 20000-21000, and CATCH EXCEPTIONS. That is how you will know if a port is unusable (used by another process, in other words) on your computer.

However, in your case, you shouldn't have a problem using a single hard-coded port for your listener, as long as you print an error message if the bind fails.

Note also that most of your sockets (for the slaves) do not need to be explicitly bound to specific port numbers - only sockets that wait for incoming connections (like your master here) will need to be made a listener and bound to a port. If a port is not specified for a socket before it is used, the OS will assign a useable port to the socket. When the master wants to respond to a slave that sends it data, the address of the sender is accessible when the listener receives data.

I presume you will be using UDP for this?

There is a problem using sqlplus to create csv files. If you want the column headers only once in the output and there are thousands or millions of rows, you cannot set pagesize large enough not to get a repeat. The solution is to start with pagesize = 50 and parse out the headers, then issue the select again with pagesize = 0 to get the data. See bash script below:

#!/bin/bash
FOLDER="csvdata_mydb"
CONN="192.168.100.11:1521/mydb0023.world"
CNT=0376
ORD="0376"
TABLE="MY_ATTACHMENTS"

sqlplus -L logn/pswd@//${CONN}<<EOF >/dev/null
set pagesize 50;
set verify off;
set feedback off;
set long 99999;
set linesize 32767;
set trimspool on;
col object_ddl format A32000;
set colsep ,;
set underline off;
set headsep off;
spool ${ORD}${TABLE}.tmp;
select * from tblspc.${TABLE} where rownum < 2;
EOF
LINES=`wc -l ${ORD}${TABLE}.tmp | cut -f1 -d" "`
[ ${LINES} -le 3 ] && {
  echo "No Data Found in ${TABLE}."
}
[ ${LINES} -gt 3 ] && {
  cat ${ORD}${TABLE}.tmp | sed -e 's/ * / /g' -e 's/^ //' -e 's/ ,/,/g' -e 's/, /,/g' | tail -n +3 | head -n 1 > ./${ORD}${TABLE}.headers
}

sqlplus -L logn/pswd@//${CONN}<<EOF >/dev/null
set pagesize 0;
set verify off;
set feedback off;
set long 99999;
set linesize 32767;
set trimspool on;
col object_ddl format A32000;
set colsep ,;
set underline off;
set headsep off;
spool ${ORD}${TABLE}.tmp;
select * from tblspc.${TABLE};
EOF
LINES=`wc -l ${ORD}${TABLE}.tmp | cut -f1 -d" "`
[ ${LINES} -le 3 ] && {
  echo "No Data Found in ${TABLE}."
}
[ ${LINES} -gt 3 ] && {
  cat ${ORD}${TABLE}.headers > ${FOLDER}/${ORD}${TABLE}.csv
  cat ${ORD}${TABLE}.tmp | sed -e 's/ * / /g' -e 's/^ //' -e 's/ ,/,/g' -e 's/, /,/g' | tail -n +2 | head -n -1 >> ${FOLDER}/${ORD}${TABLE}.csv
}

For swift 3 and 4, you can do this. Good practice is set name of Storyboard equal to StoryboardID.

enum StoryBoardName{
   case second = "SecondViewController"
}
extension UIStoryBoard{
   class func load(_ storyboard: StoryBoardName) -> UIViewController{
      return UIStoryboard(name: storyboard.rawValue, bundle: nil).instantiateViewController(withIdentifier: storyboard.rawValue)
   }
}

and then you can load your Storyboard in your ViewController like this:

class MyViewController: UIViewController{
     override func viewDidLoad() {
        super.viewDidLoad()
        guard let vc = UIStoryboard.load(.second) as? SecondViewController else {return}
        self.present(vc, animated: true, completion: nil)
     }

}

When you create a new Storyboard just set the same name on StoryboardID and add Storyboard name in your enum "StoryBoardName"

You need to use the Scatter chart type instead of Line. That will allow you to define separate X values for each series.

Why nobody wrote this simple way of converting JSON string in List ?

List<Object> list = Arrays.asList(new GsonBuilder().create().fromJson(jsonString, Object[].class));

• First, Download MySQL connector jar file, This is the latest jar file as of today [mysql-connector-java-8.0.21].

• Add the Jar file to your workspace [build path].

• Then Create a new Connection object from the DriverManager class, so you could use this Connection object to execute queries.

• Define the database name, userName, and Password for your connection.

• Use the resultSet to get the data based one the column name from your database table.

Sample code is here:

public class JdbcMySQLExample{

public static void main(String[] args) {

    String url = "jdbc:mysql://localhost:3306/YOUR_DB_NAME?useSSL=false";
    String user = "root";
    String password = "root";
    
    String query = "SELECT * from YOUR_TABLE_NAME";

    try (Connection con = DriverManager.getConnection(url, user, password);
        Statement st = con.createStatement();
        ResultSet rs = st.executeQuery(query)) {

        if (rs.next()) {
            
            System.out.println(rs.getString(1));
        }

    } catch (SQLException ex) {
          System.out.println(ex);
       
    } 
}

I would recommend Apache HTTPClient.

Warning: This function was REMOVED in PHP 7.0.0.

http://php.net/manual/en/function.mssql-query.php

For anyone still using these mssql_* functions, keep in mind that they have been removed from PHP as of v7.0.0. So, that means you eventually have to rewrite your model code to either use the PDO library, sqlsrv_* etc. If you're looking for something with a "quoting/escaping" method, I would recommend PDO.

Alternatives to this function include: PDO::query(), sqlsrv_query() and odbc_exec()

Sharing my solution here, based on Chris' answer. Hope it can help others.

I needed to dynamically append child elements into my JSX, but in a simpler way than conditional checks in my return statement. I want to show a loader in the case that the child elements aren't ready yet. Here it is:

export class Settings extends React.PureComponent {
  render() {
    const loading = (<div>I'm Loading</div>);
    let content = [];
    let pushMessages = null;
    let emailMessages = null;

    if (this.props.pushPreferences) {
       pushMessages = (<div>Push Content Here</div>);
    }
    if (this.props.emailPreferences) {
      emailMessages = (<div>Email Content Here</div>);
    }

    // Push the components in the order I want
    if (emailMessages) content.push(emailMessages);
    if (pushMessages) content.push(pushMessages);

    return (
      <div>
        {content.length ? content : loading}
      </div>
    )
}

Now, I do realize I could also just put {pushMessages} and {emailMessages} directly in my return() below, but assuming I had even more conditional content, my return() would just look cluttered.

You can also easily pass parameters to modal controller by added a new property with instance of modal and get it to modal controller. For example:

Following is my click event on which i want to open modal view.

 $scope.openMyModalView = function() {
            var modalInstance = $modal.open({
                    templateUrl: 'app/userDetailView.html',
                    controller: 'UserDetailCtrl as userDetail'
                });
                // add your parameter with modal instance
                modalInstance.userName = 'xyz';
        };

Modal Controller:

angular.module('myApp').controller('UserDetailCtrl', ['$modalInstance',
                function ($modalInstance) {
                    // get your parameter from modal instance
                    var currentUser = $modalInstance.userName;
                    // do your work...
                }]);

Using webpack and scss:

Install font-awesome using npm (using the setup instructions on https://fontawesome.com/how-to-use)

npm install @fortawesome/fontawesome-free

Next, using the copy-webpack-plugin, copy the webfonts folder from node_modules to your dist folder during your webpack build process. (https://github.com/webpack-contrib/copy-webpack-plugin)

npm install copy-webpack-plugin

In webpack.config.js, configure copy-webpack-plugin. NOTE: The default webpack 4 dist folder is "dist", so we are copying the webfonts folder from node_modules to the dist folder.

const CopyWebpackPlugin = require('copy-webpack-plugin');

module.exports = {
    plugins: [
        new CopyWebpackPlugin([
            { from: './node_modules/@fortawesome/fontawesome-free/webfonts', to: './webfonts'}
        ])
    ]
}

Lastly, in your main.scss file, tell fontawesome where the webfonts folder has been copied to and import the SCSS files you want from node_modules.

$fa-font-path: "/webfonts"; // destination folder in dist
//Adapt the path to be relative to your main.scss file
@import "../node_modules/@fortawesome/fontawesome-free/scss/fontawesome";

//Include at least one of the below, depending on what icons you want.
//Adapt the path to be relative to your main.scss file
@import "../node_modules/@fortawesome/fontawesome-free/scss/brands";
@import "../node_modules/@fortawesome/fontawesome-free/scss/regular";
@import "../node_modules/@fortawesome/fontawesome-free/scss/solid";

@import "../node_modules/@fortawesome/fontawesome-free/scss/v4-shims"; // if you also want to use `fa v4`  like: `fa fa-address-book-o` 

and apply the following font-family to a desired region(s) in your html document where you want to use the fontawesome icons.

Example:

 body {
      font-family: 'Font Awesome 5 Free'; // if you use fa v5 (regular/solid)
      // font-family: 'Font Awesome 5 Brands'; // if you use fa v5 (brands)
    }

from eclipse, you can select on the project, right click->team->upgrade

Jquery One-liners:

ES6 + jQuery:

$('#select').append([...Array(100).keys()].map((i,j) => `< option >${i}</option >`))

Lodash + jQuery:

$('#select').append(_.range(100).map(function(i,j){ return $('<option>',{text:i})}))

There are a few problems here.

1: onBlur expects a callback, and you are calling renderPasswordConfirmError and using the return value, which is null.

2: you need a place to render the error.

3: you need a flag to track "and I validating", which you would set to true on blur. You can set this to false on focus if you want, depending on your desired behavior.

handleBlur: function () {
  this.setState({validating: true});
},
render: function () {
  return <div>
    ...
    <input
        type="password"
        placeholder="Password (confirm)"
        valueLink={this.linkState('password2')}
        onBlur={this.handleBlur}
     />
    ...
    {this.renderPasswordConfirmError()}
  </div>
},
renderPasswordConfirmError: function() {
  if (this.state.validating && this.state.password !== this.state.password2) {
    return (
      <div>
        <label className="error">Please enter the same password again.</label>
      </div>
    );
  }  
  return null;
},

@The Thunder Chimp You can split text in such a way that some sections are affected by super(or sub) script and others aren't through the use of *. For your example, with splitting the word "moment" from "4th" -

plot(rnorm(30), xlab = expression('4'^th*'moment'))

SELECT CASE CHARINDEX(' ', @Foo, 1)
     WHEN 0 THEN @Foo -- empty or single word
     ELSE SUBSTRING(@Foo, 1, CHARINDEX(' ', @Foo, 1) - 1) -- multi-word
END

You could perhaps use this in a UDF:

CREATE FUNCTION [dbo].[FirstWord] (@value varchar(max))
RETURNS varchar(max)
AS
BEGIN
    RETURN CASE CHARINDEX(' ', @value, 1)
        WHEN 0 THEN @value
        ELSE SUBSTRING(@value, 1, CHARINDEX(' ', @value, 1) - 1) END
END
GO -- test:
SELECT dbo.FirstWord(NULL)
SELECT dbo.FirstWord('')
SELECT dbo.FirstWord('abc')
SELECT dbo.FirstWord('abc def')
SELECT dbo.FirstWord('abc def ghi')

I think the complete func should look like :

function siteURL()
{
    $protocol =  "http://";
    if (
        //straight
        isset($_SERVER['HTTPS']) && in_array($_SERVER['HTTPS'], ['on', 1])
        ||
        //proxy forwarding
        isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https'
    ) {
        $protocol = 'https://';
    }

    $domainName = $_SERVER['HTTP_HOST'];
    return $protocol . $domainName;
}

Notes:

• you should look also for HTTP_X_FORWARDED_PROTO (e.g. if proxy server)
• relying on 443 port is not safe (https could be served on different port)
• REQUEST_SCHEME not reliable

According to MSDN, it's 260 characters. It includes "<NUL>" -the invisible terminating null character, so the actual length is 259.

But read the article, it's a bit more complicated.

Take a look at this article; under the heading "Methods provided at runtime":

Some accessors are created dynamically at runtime, such as certain ones used in CoreData's NSManagedObject class. If you want to declare and use properties for these cases, but want to avoid warnings about methods missing at compile time, you can use the @dynamic directive instead of @synthesize.

...

Using the @dynamic directive essentially tells the compiler "don't worry about it, a method is on the way."

The @synthesize directive, on the other hand, generates the accessor methods for you at compile time (although as noted in the "Mixing Synthesized and Custom Accessors" section it is flexible and does not generate methods for you if either are implemented).

You have to instantiate the object first. The simplest way is:

var lab =["1","2","3"];
var val = [42,55,51,22];
var data = [];
for(var i=0; i<4; i++)  {
    data.push({label: lab[i], value: val[i]});
}

Or an other, less concise way, but closer to your original code:

for(var i=0; i<4; i++)  {
   data[i] = {};              // creates a new object
   data[i].label = lab[i];
   data[i].value = val[i];    
}

array() will not create a new array (unless you defined that function). Either Array() or new Array() or just [].

I recommend to read the MDN JavaScript Guide.

• When you create a stored function, you must declare either that it is deterministic or that it does not modify data. Otherwise, it may be unsafe for data recovery or replication.

• By default, for a CREATE FUNCTION statement to be accepted, at least one of DETERMINISTIC, NO SQL, or READS SQL DATA must be specified explicitly. Otherwise an error occurs:

To fix this issue add following lines After Return and Before Begin statement:

READS SQL DATA
DETERMINISTIC

For Example :

CREATE FUNCTION f2()
RETURNS CHAR(36) CHARACTER SET utf8
/*ADD HERE */
READS SQL DATA
DETERMINISTIC
BEGIN

The new ASP.NET Web API is a continuation of the previous WCF Web API project (although some of the concepts have changed).

WCF was originally created to enable SOAP-based services. For simpler RESTful or RPCish services (think clients like jQuery) ASP.NET Web API should be good choice.

For us, WCF is used for SOAP and Web API for REST. I wish Web API supported SOAP too. We are not using advanced features of WCF. Here is comparison from MSDN:

ASP.net Web API is all about HTTP and REST based GET,POST,PUT,DELETE with well know ASP.net MVC style of programming and JSON returnable; web API is for all the light weight process and pure HTTP based components. For one to go ahead with WCF even for simple or simplest single web service it will bring all the extra baggage. For light weight simple service for ajax or dynamic calls always WebApi just solves the need. This neatly complements or helps in parallel to the ASP.net MVC.

Check out the podcast : Hanselminutes Podcast 264 - This is not your father's WCF - All about the WebAPI with Glenn Block by Scott Hanselman for more information.

In the scenarios listed below you should go for WCF:

1. If you need to send data on protocols like TCP, MSMQ or MIME
2. If the consuming client just knows how to consume SOAP messages

WEB API is a framework for developing RESTful/HTTP services.

There are so many clients that do not understand SOAP like Browsers, HTML5, in those cases WEB APIs are a good choice.

HTTP services header specifies how to secure service, how to cache the information, type of the message body and HTTP body can specify any type of content like HTML not just XML as SOAP services.

It's not clear what you want, or whether you want this trick to work with different targets, or whether you've defined these targets elsewhere, or what version of Make you're using, but what the heck, I'll go out on a limb:

ifeq (yes, ${TEST})
CXXFLAGS := ${CXXFLAGS} -DDESKTOP_TEST
test:
$(info ************  TEST VERSION ************)
else
release:
$(info ************ RELEASE VERSIOIN **********)
endif

Just use
<Table cellpadding="10" ..> ... </Table>
Don't use px.Works in MS-Outlook.

Talk is cheap, show you the code:

>>> i = 50
>>> print '%d      %s'%(i,tup)
50  (10, 20, 30)
>>> print '%s'%(tup,)
(10, 20, 30)

Today we use Bearer token more often that Basic Authentication but if you want to have Basic Authentication first to get Bearer token then there is a couple ways:

const request = new XMLHttpRequest();
request.open('GET', url, false, username,password)
request.onreadystatechange = function() {
        // D some business logics here if you receive return
   if(request.readyState === 4 && request.status === 200) {
       console.log(request.responseText);
   }
}
request.send()

Full syntax is here

Second Approach using Ajax:

$.ajax
({
  type: "GET",
  url: "abc.xyz",
  dataType: 'json',
  async: false,
  username: "username",
  password: "password",
  data: '{ "key":"sample" }',
  success: function (){
    alert('Thanks for your up vote!');
  }
});

Hopefully, this provides you a hint where to start API calls with JS. In Frameworks like Angular, React, etc there are more powerful ways to make API call with Basic Authentication or Oauth Authentication. Just explore it.

It doesn't sound like a good idea to use send message. I think you should try to work around the problem that the DLLs can't reference each other...

In case you need to download an artifact in a Dockerfile, instead of using wget or curl or the likes you can simply use the 'ADD' directive:

ADD ${ARTIFACT_URL} /opt/app/app.jar

Of course, the tricky part is determining the ARTIFACT_URL, but there's enough about that in all the other answers.

However, Docker best practises strongly discourage using ADD for this purpose and recommend using wget or curl.

There's also the iScroll project which allows you to style the scrollbars plus get it to work with touch devices. http://cubiq.org/iscroll-4

Don't want to be repetitive, but just to summarize in other way (features added in new HttpClient):

• Automatic conversion from JSON to an object
• Response type definition
• Event firing
• Simplified syntax for headers
• Interceptors

I wrote an article, where I covered the difference between old "http" and new "HttpClient". The goal was to explain it in the easiest way possible.

Simply about new HttpClient in Angular

This is the right way to compare strings:

int studentCompare = this.lastName.compareTo(s.getLastName()); 

This won't even compile:

if (this.getLastName() < s.getLastName())

Use if (this.getLastName().compareTo(s.getLastName()) < 0) instead.

So to compare fist/last name order you need:

int d = getFirstName().compareTo(s.getFirstName());
if (d == 0)
    d = getLastName().compareTo(s.getLastName());
return d;

In my case the program (elinks) returned lines that looked empty, but in fact had special terminal characters, color control codes and backspace, so grep options presented in other answers did not work for me. So I wrote this small script in Node.js. I called the file tight, but that's just a random name.

#!/usr/bin/env node

function visible(a) {
    var R  =  ''
    for (var i = 0; i < a.length; i++) {
        if (a[i] == '\b') {  R -= 1; continue; }  
        if (a[i] == '\u001b') {
            while (a[i] != 'm' && i < a.length) i++
            if (a[i] == undefined) break
        }
        else R += a[i]
    }
    return  R
}

function empty(a) {
    a = visible(a)
    for (var i = 0; i < a.length; i++) {
        if (a[i] != ' ') return false
    }
    return  true
}

})

If the visual studio says that you miss some file in the current source file folder, there is one solution that i used. Just right click the file you want to add and choose Open Document, if it really doesn't exist, then you should see something like cannot find file in the source file path = "somewhere in your computer", then what you could do is the add your source file into that path first and see if it works.

I'm not sure exactly what you're trying to do but you can set the date/time to exactly what you want in a number of ways...

You can specify 12/25/2010 4:58 PM by using

DateTime myDate = Convert.ToDateTime("2010-12-25 16:58:00");

OR if you have an existing datetime construct , say 12/25/2010 (and any random time) and you want to set it to 12/25/2010 4:58 PM, you could do so like this:

DateTime myDate = ExistingTime.Date.AddHours(16).AddMinutes(58);

The ExistingTime.Date will be 12/25 at midnight, and you just add hours and minutes to get it to the time you want.

The answer are as below for Window authentication

$SqlConnection.ConnectionString = "Server=$SQLServer;Database=$SQLDBName;Integrated Security=True;"

I have a simple form to submit testimonials, I also was having trouble clearing the form, what I did was after the query is submitted successfully I and before redirecting to another page I cleared the imputs $name =''; ect. The page submitted and redirected with no errors.

My issue was related to the use of a Filter together with the ListView.

When setting or updating the underlying data model of the ListView, I was doing something like this:

public void updateUnderlyingContacts(List<Contact> newContacts, String filter)
{
    this.allContacts = newContacts;
    this.filteredContacts = newContacts;
    getFilter().filter(filter);
}

Calling filter() in the last line will (and must) cause notifyDataSetChanged() to be called in the Filter's publishResults() method. This may work okay sometimes, specially in my fast Nexus 5. But in reality, it's hiding a bug that you will notice with slower devices or in resource intensive conditions.

The problem is that the filtering is done asynchronously, and thus between the end of the filter() statement and the call to publishResults(), both in the UI thread, some other UI thread code may execute and change the content of the adapter.

The actual fix is easy, just call notifyDataSetChanged() also before requesting the filtering to be performed:

public void updateUnderlyingContacts(List<Contact> newContacts, String filter)
{
    this.allContacts = newContacts;
    this.filteredContacts = newContacts;
    notifyDataSetChanged(); // Fix
    getFilter().filter(filter);
}

ES6 is quite powerful in iterating through objects (strings, Array, Map, Set). Let's use a Spread Operator to solve this.

entry = prompt("Enter your name");
var count = [...entry];
console.log(count);

Here are two approaches. You may want to add handling for when the array is empty.

public static void FindMax()
{
    // Advantages: 
    // * Functional approach
    // * Compact code
    // Cons: 
    // * We are indexing into the array twice at each step
    // * The Range and IEnumerable add a bit of overhead
    // * Many people will find this code harder to understand

    int[] array = { 1, 5, 2, 7 };

    int maxIndex = Enumerable.Range(0, array.Length).Aggregate((max, i) => array[max] > array[i] ? max : i);
    int maxInt = array[maxIndex];

    Console.WriteLine($"Maximum int {maxInt} is found at index {maxIndex}");
}

public static void FindMax2()
{
    // Advantages: 
    // * Near-optimal performance

    int[] array = { 1, 5, 2, 7 };
    int maxIndex = -1;
    int maxInt = Int32.MinValue;

    // Modern C# compilers optimize the case where we put array.Length in the condition
    for (int i = 0; i < array.Length; i++)
    {
        int value = array[i];
        if (value > maxInt)
        {
            maxInt = value;
            maxIndex = i;
        }
    }

    Console.WriteLine($"Maximum int {maxInt} is found at index {maxIndex}");
}

I would recommend using Wireshark, which has a "Follow TCP Stream" option that makes it very easy to see the full requests and responses for a particular TCP connection. If you would prefer to use the command line, you can try tcpflow, a tool dedicated to capturing and reconstructing the contents of TCP streams.

Other options would be using an HTTP debugging proxy, like Charles or Fiddler as EricLaw suggests. These have the advantage of having specific support for HTTP to make it easier to deal with various sorts of encodings, and other features like saving requests to replay them or editing requests.

You could also use a tool like Firebug (Firefox), Web Inspector (Safari, Chrome, and other WebKit-based browsers), or Opera Dragonfly, all of which provide some ability to view the request and response headers and bodies (though most of them don't allow you to see the exact byte stream, but instead how the browsers parsed the requests).

And finally, you can always construct requests by hand, using something like telnet, netcat, or socat to connect to port 80 and type the request in manually, or a tool like htty to help easily construct a request and inspect the response.

Today NodeJS supports new async/await syntax. This is an easy syntax and makes the life much easier

async function process(promises) { // must be an async function
    let x = await Promise.all(promises);  // now x will be an array
    x = x.map( tmp => tmp * 10);              // proccessing the data.
}

const promises = [
   new Promise(resolve => setTimeout(resolve, 0, 1)),
   new Promise(resolve => setTimeout(resolve, 0, 2))
];

process(promises)

It happens occasionally that when I restart my computer, everything is OK. Perhaps there is a port conflict.

Restart the computer works because instances of Java or Tomcat are killed during the restart. You can also consider killing the specific processes from Task Manager

This also happens if there is an issue in the context.xml file. In my case, I had accidentally changed the context value.

I'll try to keep this short, I've done this a few months ago for a game I was trying to build, it does a UDP "Client-Server" connection that acts like TCP, you can send (message) (message + object) using this. I've done some testing with it and it works just fine, feel free to modify it if needed.

This probably does not answer your question, but I had the same question and it answered mine.

I changed Private Function to Public Function and it worked.

Something like this - a riff on @maarten-vanlinthout's answer

ip  -f inet a show eth0| grep inet| awk '{ print $2}' | cut -d/ -f1

I occasionally have the same issue but mostly after macOS upgrades. Shutting down and migrating to the new version usually fixes it for me(make changes according to your version). So first upgrade your postgresql

brew services stop postgresql@12
brew services start postgresql@12
brew postgresql-upgrade-database

This is mostly a temporary fix but since I couldn't find a better solution this works for me.

Update: If the issue says that another postmaster is running then try removing it from that location(your postmaster.pid location will be displayed to you)

rm /usr/local/var/postgres/postmaster.pid

The formula in C1

=IF(A1=1,B1,"")

is either giving an answer of "" (which isn't treated as blank) or the contents of B1.

If you want the formula in D1 to show TRUE if C1 is "" and FALSE if C1 has something else in then use the formula

=IF(C2="",TRUE,FALSE)

instead of ISBLANK

your http service file:

import { Injectable } from "@angular/core";
import { ActivatedRoute, Router } from '@angular/router';
import { Http, Headers, Response, Request, RequestMethod, URLSearchParams, RequestOptions } from "@angular/http";
import {Observable} from 'rxjs/Rx';
import { Constants } from './constants';
declare var $: any;

@Injectable()
export class HttpClient {
  requestUrl: string;
  responseData: any;
  handleError: any;

  constructor(private router: Router, 
  private http: Http, 
  private constants: Constants, 
  ) {
    this.http = http;
  }

  postWithFile (url: string, postData: any, files: File[]) {

    let headers = new Headers();
    let formData:FormData = new FormData();
    formData.append('files', files[0], files[0].name);
    // For multiple files
    // for (let i = 0; i < files.length; i++) {
    //     formData.append(`files[]`, files[i], files[i].name);
    // }

    if(postData !=="" && postData !== undefined && postData !==null){
      for (var property in postData) {
          if (postData.hasOwnProperty(property)) {
              formData.append(property, postData[property]);
          }
      }
    }
    var returnReponse = new Promise((resolve, reject) => {
      this.http.post(this.constants.root_dir + url, formData, {
        headers: headers
      }).subscribe(
          res => {
            this.responseData = res.json();
            resolve(this.responseData);
          },
          error => {
            this.router.navigate(['/login']);
            reject(error);
          }
      );
    });
    return returnReponse;
  }
}

call your function (Component file):

onChange(event) {
    let file = event.srcElement.files;
    let postData = {field1:"field1", field2:"field2"}; // Put your form data variable. This is only example.
    this._service.postWithFile(this.baseUrl + "add-update",postData,file).then(result => {
        console.log(result);
    });
}

your html code:

<input type="file" class="form-control" name="documents" (change)="onChange($event)" [(ngModel)]="stock.documents" #documents="ngModel">

    inflater = getMenuInflater();
    inflater.inflate(R.menu.menu_otp_skip, menu);
    return true;
}

    switch (item.getItemId()) {
        // action with ID action_refresh was selected
        case R.id.menu_item_skip:
            Toast.makeText(this, "Skip selected", Toast.LENGTH_SHORT)
                    .show();
            break;
        default:
            break;
    }
    return true;
}

You can connect your XML schema to Microsoft Visual Studio's Intellisense. This option gives you both real-time validation AND autocomplete, which is just awesome.

I have this exact scenario running on my free copy of Microsoft Visual C++ 2010 Express.

As far as I know, basic animates can't animate non-numeric CSS properties.

I believe you could get this done using a step function and the appropriate css3 transform for the users browser. CSS3 transform is a bit tricky to cover all your browsers in (IE6 you need to use the Matrix filter, for instance).

EDIT: here's an example that works in webkit browsers (Chrome, Safari): http://jsfiddle.net/ryleyb/ERRmd/

If you wanted to support IE9 only, you could use transform instead of -webkit-transform, or -moz-transform would support FireFox.

The trick used is to animate a CSS property we don't care about (text-indent) and then use its value in a step function to do the rotation:

$('#foo').animate(
..
step: function(now,fx) {
  $(this).css('-webkit-transform','rotate('+now+'deg)'); 
}
...

You need to find the key of the array first, this can be done using array_search()

Once done, use the unset()

<?php
$array = array( 'apple', 'orange', 'pear' );

unset( $array[array_search( 'orange', $array )] );
?>

• Wrap radio and image in <label>
• Hide radio button (Don't use display:none or visibility:hidden since such will impact accessibility)
• Target the image next to the hidden radio using Adjacent sibling selector +

/* HIDE RADIO */
[type=radio] { 
  position: absolute;
  opacity: 0;
  width: 0;
  height: 0;
}

/* IMAGE STYLES */
[type=radio] + img {
  cursor: pointer;
}

/* CHECKED STYLES */
[type=radio]:checked + img {
  outline: 2px solid #f00;
}

<label>
  <input type="radio" name="test" value="small" checked>
  <img src="http://placehold.it/40x60/0bf/fff&text=A">
</label>

<label>
  <input type="radio" name="test" value="big">
  <img src="http://placehold.it/40x60/b0f/fff&text=B">
</label>

_{Don't forget to add a class to your labels and in CSS use that class instead.}

A simple (but not very fast) method to calculate the square root of X:

squareroot(x)
    if x<0 then Error
    a = 1
    b = x
    while (abs(a-b)>ErrorMargin) 
        a = (a+b)/2
        b = x/a
    endwhile
    return a;

Example: squareroot(70000)

    a       b
    1   70000
35001       2
17502       4
 8753       8
 4381      16
 2199      32
 1116      63
  590     119
  355     197
  276     254
  265     264

As you can see it defines an upper and a lower boundary for the square root and narrows the boundary until its size is acceptable.

There are more efficient methods but this one illustrates the process and is easy to understand.

Just beware to set the Errormargin to 1 if using integers else you have an endless loop.

here is a small snippet that might be cool to try out:

input {
border-radius: 10px;
border-color: violet;
border-style: solid;
}

note that: border-style removes the inner shadow.

input {_x000D_
    border-radius: 10px;_x000D_
    border-color: violet;_x000D_
    border-style: solid;_x000D_
  }

<input type="text"/>

The default Gson implementation of Map serialization uses toString() on the key:

Gson gson = new GsonBuilder()
        .setPrettyPrinting().create();
Map<Point, String> original = new HashMap<>();
original.put(new Point(1, 2), "a");
original.put(new Point(3, 4), "b");
System.out.println(gson.toJson(original));

Will give:

{
  "java.awt.Point[x\u003d1,y\u003d2]": "a",
  "java.awt.Point[x\u003d3,y\u003d4]": "b"
}

Using enableComplexMapKeySerialization

If you want the Map Key to be serialized according to default Gson rules you can use enableComplexMapKeySerialization. This will return an array of arrays of key-value pairs:

Gson gson = new GsonBuilder().enableComplexMapKeySerialization()
        .setPrettyPrinting().create();
Map<Point, String> original = new HashMap<>();
original.put(new Point(1, 2), "a");
original.put(new Point(3, 4), "b");
System.out.println(gson.toJson(original));

Will return:

[
  [
    {
      "x": 1,
      "y": 2
    },
    "a"
  ],
  [
    {
      "x": 3,
      "y": 4
    },
    "b"
  ]
]

Based on all the previous answers:

public static String join(Iterable<? extends Object> elements, CharSequence separator) 
{
    StringBuilder builder = new StringBuilder();

    if (elements != null)
    {
        Iterator<? extends Object> iter = elements.iterator();
        if(iter.hasNext())
        {
            builder.append( String.valueOf( iter.next() ) );
            while(iter.hasNext())
            {
                builder
                    .append( separator )
                    .append( String.valueOf( iter.next() ) );
            }
        }
    }

    return builder.toString();
}

Have a look at override_function to override the functions.

override_function — Overrides built-in functions

Example:

override_function('test', '$a,$b', 'echo "DOING TEST"; return $a * $b;');

You can also use command palette:

1. (CTRL+SHIFT+P - Win) or (CMD+SHIFT+P - Mac) to open the palette.
2. Enter 'git', select Git:Clone,
3. paste github repo URL (https://github.com/Username/repo),
4. than you are ready to go with Source control section from the left menu.

Does the same thing as the terminal.

You can 'learn' the size of the array automatically:

template<typename T, size_t N>
void set_data(const T (&w)[N]){
    w_.assign(w, w+N);
}

Hopefully, you can change the interface to set_data as above. It still accepts a C-style array as its first argument. It just happens to take it by reference.

How it works

[ Update: See here for a more comprehensive discussion on learning the size ]

Here is a more general solution:

template<typename T, size_t N>
void copy_from_array(vector<T> &target_vector, const T (&source_array)[N]) {
    target_vector.assign(source_array, source_array+N);
}

This works because the array is being passed as a reference-to-an-array. In C/C++, you cannot pass an array as a function, instead it will decay to a pointer and you lose the size. But in C++, you can pass a reference to the array.

Passing an array by reference requires the types to match up exactly. The size of an array is part of its type. This means we can use the template parameter N to learn the size for us.

It might be even simpler to have this function which returns a vector. With appropriate compiler optimizations in effect, this should be faster than it looks.

template<typename T, size_t N>
vector<T> convert_array_to_vector(const T (&source_array)[N]) {
    return vector<T>(source_array, source_array+N);
}

Use IEquatable<T> Interface which has a method Equals.

The correct way to use LOCK TABLES and UNLOCK TABLES with transactional tables, such as InnoDB tables, is to begin a transaction with SET autocommit = 0 (not START TRANSACTION) followed by LOCK TABLES, and to not call UNLOCK TABLES until you commit the transaction explicitly. For example, if you need to write to table t1 and read from table t2, you can do this:

SET autocommit=0;
LOCK TABLES t1 WRITE, t2 READ, ...;... do something with tables t1 and t2 here ...
COMMIT;
UNLOCK TABLES;

I tried many GUI's, and the best for me continue being "SQLyog-comunity" by using wine. Is complete, is nice, and is intuitive. (and in wine work perfect)

Seems we could use a new HTML5 feature if the browser version is not a problem:

in HTML files :

<div class="centerBloc">
  I will be in the center
</div>

And in CSS file, we write:

body .centerBloc {
  position: fixed;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

And so the div could be perfectly center in browser.

I generally just put a log4j.xml file into src/test/resources and let log4j find it by itself: no code required, the default log4j initialisation will pick it up. (I typically want to set my own loggers to 'DEBUG' anyway)

Watch out for the parentheses. As has been pointed out above, in Python 3, assert is still a statement, so by analogy with print(..), one may extrapolate the same to assert(..) or raise(..) but you shouldn't.

This is important because:

assert(2 + 2 == 5, "Houston we've got a problem")

won't work, unlike

assert 2 + 2 == 5, "Houston we've got a problem"

The reason the first one will not work is that bool( (False, "Houston we've got a problem") ) evaluates to True.

In the statement assert(False), these are just redundant parentheses around False, which evaluate to their contents. But with assert(False,) the parentheses are now a tuple, and a non-empty tuple evaluates to True in a boolean context.

try this:

.test {
    position:absolute;
    background:blue;
    width:200px;
    height:200px;
    top:40px;
    transition:left 1s linear;
    left: 0;
}

Python supports a "bignum" integer type which can work with arbitrarily large numbers. In Python 2.5+, this type is called long and is separate from the int type, but the interpreter will automatically use whichever is more appropriate. In Python 3.0+, the int type has been dropped completely.

That's just an implementation detail, though — as long as you have version 2.5 or better, just perform standard math operations and any number which exceeds the boundaries of 32-bit math will be automatically (and transparently) converted to a bignum.

You can find all the gory details in PEP 0237.

I prefer to do it in a more direct fashion. It does not have the Rows but is still has the array of rows.

tblCrm.DefaultView.RowFilter = "customertype = 'new'";

qtytotal = 0;
for (int i = 0; i < tblCrm.DefaultView.Count; i++)
{
    result = double.TryParse(tblCrm.DefaultView[i]["qty"].ToString(), out num);
    if (result == false) num = 0;
    qtytotal = qtytotal + num;
}

labQty.Text = qtytotal.ToString();

I use std::getwchar() in my environment which is with mingw32 - gcc-4.6.2 compiler, Here is a sample code.

#include <iostream>
#include "Arithmetics.h"

using namespace std;

int main() {
    ARITHMETICS_H::testPriorities();

    cout << "Press any key to exit." << endl;
    getwchar();
    return 0;
}

You can use IntArrays.quickSort(array, comparator) from fastutil library.

Anybody working on legacy software using Visual Studio 6.0 will find that $(Configuration) and $(ProjectDir) macro's are not defined. For post-build/pre-build events, give a relative path starting with the location of your .dsw file(workspace) as the starting point. In relative path dot represents the current directory and .. represents the parent directory. Give a relative path to the file that need to be processed. Example: ( copy /y .\..\..\Debug\mylib.dll .\..\MyProject\Debug\ )

The tcpdump tool is available under gnu.

You can use it instead of wireshark.

add a condition to check for the admin directory, something like:

RewriteCond %{REQUEST_URI} !^/?(admin|user)/
RewriteRule ^([^/] )/([^/] )\.html$ index.php?lang=$1&mod=$2 [L]

RewriteCond %{REQUEST_URI} !^/?(admin|user)/
RewriteRule ^([^/] )/$ index.php?lang=$1&mod=home [L]

The way that worked for me is to use a bind mount

  version: "3.7"    
  services:
  app:
    image: app:latest
    volumes:
      - type: bind
        source: ./sourceFile.yaml
        target: /location/targetFile.yaml

Thanks mike breed for the answer over at: Mount single file from volume using docker-compose

You need to use the "long syntax" to express a bind mount using the volumes key: https://docs.docker.com/compose/compose-file/#long-syntax-3

There's no problem with using a localhost url for Dev work - obviously it needs to be changed when it comes to production.

You need to go here: https://developers.google.com/accounts/docs/OAuth2 and then follow the link for the API Console - link's in the Basic Steps section. When you've filled out the new application form you'll be asked to provide a redirect Url. Put in the page you want to go to once access has been granted.

When forming the Google oAuth Url - you need to include the redirect url - it has to be an exact match or you'll have problems. It also needs to be UrlEncoded.
