The form tag needs some attributes set:

1. action: The URL that the form data is sent to on submit. Generate it with url_for. It can be omitted if the same URL handles showing the form and processing the data.
2. method="post": Submits the data as form data with the POST method. If not given, or explicitly set to get, the data is submitted in the query string (request.args) with the GET method instead.
3. enctype="multipart/form-data": When the form contains file inputs, it must have this encoding set, otherwise the files will not be uploaded and Flask won't see them.

The input tag needs a name parameter.

Add a view to handle the submitted data, which is in request.form under the same key as the input's name. Any file inputs will be in request.files.

@app.route('/handle_data', methods=['POST'])
def handle_data():
    projectpath = request.form['projectFilepath']
    # your code
    # return a response

Set the form's action to that view's URL using url_for:

<form action="{{ url_for('handle_data') }}" method="post">
    <input type="text" name="projectFilepath">
    <input type="submit">
</form>

if you have used curl above the page and below your html is present and unfortunately your html page is not able to view then just enable your curl. But in order to check CURL is enable or not in php you need to write following code:

echo 'Curl: ', function_exists('curl_version') ? 'Enabled' : 'Disabled';

Put that file in assets.

For project created in Android Studio project you need to create assets folder under the main folder.

Read that file as:

public String loadJSONFromAsset(Context context) {
        String json = null;
        try {
            InputStream is = context.getAssets().open("file_name.json");

            int size = is.available();

            byte[] buffer = new byte[size];

            is.read(buffer);

            is.close();

            json = new String(buffer, "UTF-8");


        } catch (IOException ex) {
            ex.printStackTrace();
            return null;
        }
        return json;

    }

and then you can simply read this string return by this function as

JSONObject obj = new JSONObject(json_return_by_the_function);

For further details regarding JSON see http://www.vogella.com/articles/AndroidJSON/article.html

Hope you will get what you want.

It's a little difficult to tell what you're trying to achieve, but assuming you're trying to get a Base64 string that when decoded is abcdef==, the following should work:

byte[] bytes = Encoding.UTF8.GetBytes("abcdef==");
string base64 = Convert.ToBase64String(bytes);
Console.WriteLine(base64);

This will output: YWJjZGVmPT0= which is abcdef== encoded in Base64.

Edit:

To decode a Base64 string, simply use Convert.FromBase64String(). E.g.

string base64 = "YWJjZGVmPT0=";
byte[] bytes = Convert.FromBase64String(base64);

At this point, bytes will be a byte[] (not a string). If we know that the byte array represents a string in UTF8, then it can be converted back to the string form using:

string str = Encoding.UTF8.GetString(bytes);
Console.WriteLine(str);

This will output the original input string, abcdef== in this case.

just add system("pause") at the end of the code before return 0 like this

#include <stdlib.h>

int main()
{
    //some code goes here
    system("pause")
    return 0;
}

Just a small detail that I think is missing in above answers.

If your child activity can be opened from multiple parent activities then you can check if you need to do setResult or not, based on if your activity was opened by startActivity or startActivityForResult. You can achieve this by using getCallingActivity(). More info here.

You need to install ssh2 lib

sudo apt-get install libssh2-php && sudo /etc/init.d/apache2 restart

that should be enough to get you on the road

I was not sure about the tests in OP. I decided to experiment a little and ended up busting some of the myths.

Synchronous <script src...> will block downloading of the resources below it until it is downloaded and executed

This is no longer true. Have a look at the waterfall generated by Chrome 63:

<head>
<script src="//alias-0.redacted.com/payload.php?type=js&amp;delay=333&amp;rand=1"></script>
<script src="//alias-1.redacted.com/payload.php?type=js&amp;delay=333&amp;rand=2"></script>
<script src="//alias-2.redacted.com/payload.php?type=js&amp;delay=333&amp;rand=3"></script>
</head>

<link rel=stylesheet> will not block download and execution of scripts below it

This is incorrect. The stylesheet will not block download but it will block execution of the script (little explanation here). Have a look at performance chart generated by Chrome 63:

<link href="//alias-0.redacted.com/payload.php?type=css&amp;delay=666" rel="stylesheet">
<script src="//alias-1.redacted.com/payload.php?type=js&amp;delay=333&amp;block=1000"></script>

Keeping the above in mind, the results in OP can be explained as follows:

CSS First:

If you're in the middle of a commit (i.e. in your editor already), you can cancel it by deleting all lines above the first #. That will abort the commit.

So you can delete all lines so that the commit message is empty, then save the file:

You'll then get a message that says Aborting commit due to empty commit message..

EDIT:

You can also delete all the lines and the result will be exactly the same.

To delete all lines in vim (if that is your default editor), once you're in the editor, type gg to go to the first line, then dG to delete all lines. Finally, write and quit the file with wq and your commit will be aborted.

Both are effectively the same class (you can look at the disassembly). HashTable was created first before .Net had generics. Dictionary, however is a generic class and gives you strong typing benefits. I would never use HashTable since Dictionary costs you nothing to use.

I'd just like to detail a few things in Greg Hewgil's accepted answer. According to the Git Pocket Guide

Branch:

the branch itself is defined as all points reachable in the commit graph from the named commit (the “tip” of the branch).

HEAD: A special type of Ref

The special ref HEAD determines what branch you are on...

Refs

Git defines two kinds of references, or named pointers, which it calls “refs”:

• A simple ref, which points directly to an object ID (usually a commit or tag)
• A symbolic ref (or symref), which points to another ref (either simple or symbolic)

As Greg mentioned, HEAD can be in a "detached state". So HEAD can be either a simple ref (for a detached HEAD) or a symref.

if HEAD is a symbolic ref for an existing branch, then you are “on” that branch. If, on the other hand, HEAD is a simple ref directly naming a commit by its SHA-1 ID, then you are not “on” any branch, but rather in “detached HEAD” mode, which happens when you check out some earlier commit to examine.

Array slicing like in Python (From the rebash library):

array_slice() {
    local __doc__='
    Returns a slice of an array (similar to Python).

    From the Python documentation:
    One way to remember how slices work is to think of the indices as pointing
    between elements, with the left edge of the first character numbered 0.
    Then the right edge of the last element of an array of length n has
    index n, for example:
    ```
    +---+---+---+---+---+---+
    | 0 | 1 | 2 | 3 | 4 | 5 |
    +---+---+---+---+---+---+
    0   1   2   3   4   5   6
    -6  -5  -4  -3  -2  -1
    ```

    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 1:-2 "${a[@]}")
    1 2 3
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 0:1 "${a[@]}")
    0
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice 1:1 "${a[@]}")" ] && echo empty
    empty
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice 2:1 "${a[@]}")" ] && echo empty
    empty
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice -2:-3 "${a[@]}")" ] && echo empty
    empty
    >>> [ -z "$(array.slice -2:-2 "${a[@]}")" ] && echo empty
    empty

    Slice indices have useful defaults; an omitted first index defaults to
    zero, an omitted second index defaults to the size of the string being
    sliced.
    >>> local a=(0 1 2 3 4 5)
    >>> # from the beginning to position 2 (excluded)
    >>> echo $(array.slice 0:2 "${a[@]}")
    >>> echo $(array.slice :2 "${a[@]}")
    0 1
    0 1

    >>> local a=(0 1 2 3 4 5)
    >>> # from position 3 (included) to the end
    >>> echo $(array.slice 3:"${#a[@]}" "${a[@]}")
    >>> echo $(array.slice 3: "${a[@]}")
    3 4 5
    3 4 5

    >>> local a=(0 1 2 3 4 5)
    >>> # from the second-last (included) to the end
    >>> echo $(array.slice -2:"${#a[@]}" "${a[@]}")
    >>> echo $(array.slice -2: "${a[@]}")
    4 5
    4 5

    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -4:-2 "${a[@]}")
    2 3

    If no range is given, it works like normal array indices.
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -1 "${a[@]}")
    5
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -2 "${a[@]}")
    4
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 0 "${a[@]}")
    0
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 1 "${a[@]}")
    1
    >>> local a=(0 1 2 3 4 5)
    >>> array.slice 6 "${a[@]}"; echo $?
    1
    >>> local a=(0 1 2 3 4 5)
    >>> array.slice -7 "${a[@]}"; echo $?
    1
    '
    local start end array_length length
    if [[ $1 == *:* ]]; then

No. The JSON spec, as maintained at http://json.org, does not allow trailing commas. From what I've seen, some parsers may silently allow them when reading a JSON string, while others will throw errors. For interoperability, you shouldn't include it.

The code above could be restructured, either to remove the trailing comma when adding the array terminator or to add the comma before items, skipping that for the first one.

To make an element have a line break afterwards, assign it:

display:block;

Non-floated elements after a block level element will appear on the next line. Many elements, such as <p> and <div> are already block level elements so you can just use those.

But while this is good to know, this really depends more on the context of your content. In your example, you would not want to use CSS to force a line break. The <br /> is appropriate because semantically the p tag is the the most appropriate for the text you are displaying. More markup just to hang CSS off it is unnecessary. Technically it's not exactly a paragraph, but there is no <greeting> tag, so use what you have. Describing your content well with HTMl is way more important - after you have that then figure out how to make it look pretty.

You can use jsonpipe if you just need the output (and more comfortable with command line):

cat bookmarks.json | jsonpipe |grep uri

If the above solution does not work for you it is may be possible to obtain the same result with the following pure nodejs code. The above did not work for me and resulted in a compilation exception when running 'npm install iconv' on OSX:

fs.readFileSync() returns a Buffer if no encoding is specified. And Buffer has a toString() method that will convert to UTF8 if no encoding is specified giving you the file's contents. See the nodejs documentation. This worked for me.

sed '/^abc$/,/^mno$/!d;//d' file

golfs two characters better than ppotong's {//!b};d

The empty forward slashes // mean: "reuse the last regular expression used". and the command does the same as the more understandable:

sed '/^abc$/,/^mno$/!d;/^abc$/d;/^mno$/d' file

This seems to be POSIX:

If an RE is empty (that is, no pattern is specified) sed shall behave as if the last RE used in the last command applied (either as an address or as part of a substitute command) was specified.

There is an extension available, npm Script runner. I have not tried it myself, though.

MySQL will execute this query:

I had the same issue on the macosx and I renamed .pgadmin (in /users/costa) to .pgadminx and I was able to start pgAdmin4.

This is not the best practice in .NET framework (4 & +) to check equality

String.Compare(x.Username, (string)drUser["Username"], 
                  StringComparison.OrdinalIgnoreCase) == 0

Use the following instead

String.Equals(x.Username, (string)drUser["Username"], 
                   StringComparison.OrdinalIgnoreCase) 

MSDN recommends:

• Use an overload of the String.Equals method to test whether two strings are equal.
• Use the String.Compare and String.CompareTo methods to sort strings, not to check for equality.

Yes -- parseFloat.

parseFloat(document.getElementById(amtid4).innerHTML);

For formatting numbers, use toFixed:

var num = parseFloat(document.getElementById(amtid4).innerHTML).toFixed(2);

num is now a string with the number formatted with two decimal places.

When I use Junit4, import junit.framework.Assert; import junit.framework.TestCase; the warning info is :The type of Assert is deprecated

when import like this: import org.junit.Assert; import org.junit.Test; the warning has disappeared

I agree with some of the above answers. I would just recommend replacing "time()-1000" with "1". A value of "1" means January 1st, 1970, which ensures expiration 100%. Therefore:

setcookie($name, '', 1);
setcookie($name, '', 1, '/');

The sp_xml_preparedocument stored procedure will parse the XML and the OPENXML rowset provider will show you a relational view of the XML data.

For details and more examples check the OPENXML documentation.

As for your question,

DECLARE @XML XML

What did I do wrong? How do I resolve the issue?

Here :

Map<String,String> someMap = (Map<String,String>)getApplicationContext().getBean("someMap");

You use a legacy method that we generally don't want to use since that returns Object:

Object getBean(String name) throws BeansException;

The method to favor to get (for singleton) / create (for prototype) a bean from a bean factory is :

<T> T getBean(String name, Class<T> requiredType) throws BeansException;

Using it such as :

Map<String,String> someMap = app.getBean(Map.class,"someMap");

will compile but still with a unchecked conversion warning since all Map objects are not necessarily Map<String, String> objects.

But <T> T getBean(String name, Class<T> requiredType) throws BeansException; is not enough in bean generic classes such as generic collections since that requires to specify more than one class as parameter : the collection type and its generic type(s).

In this kind of scenario and in general, a better approach is not to use directly BeanFactory methods but let the framework to inject the bean.

The bean declaration :

@Configuration
public class MyConfiguration{

    @Bean
    public Map<String, String> someMap() {
        Map<String, String> someMap = new HashMap();
        someMap.put("some_key", "some value");
        someMap.put("some_key_2", "some value");
        return someMap;
    }
}

The bean injection :

@Autowired
@Qualifier("someMap")
Map<String, String> someMap;

Like this.

import java.util.Date;
import java.util.GregorianCalendar;

/**
 * DateDiff -- compute the difference between two dates.
 */
public class DateDiff {
  public static void main(String[] av) {
    /** The date at the end of the last century */
    Date d1 = new GregorianCalendar(2000, 11, 31, 23, 59).getTime();

    /** Today's date */
    Date today = new Date();

    // Get msec from each, and subtract.
    long diff = today.getTime() - d1.getTime();

    System.out.println("The 21st century (up to " + today + ") is "
        + (diff / (1000 * 60 * 60 * 24)) + " days old.");
  }

}

Here is an article on Java date arithmetic.

To deselect all rows and cells in a DataGridView, you can use the ClearSelection method:

myDataGridView.ClearSelection()

If you don't want even the first row/cell to appear selected, you can set the CurrentCell property to Nothing/null, which will temporarily hide the focus rectangle until the control receives focus again:

myDataGridView.CurrentCell = Nothing

To determine when the user has clicked on a blank part of the DataGridView, you're going to have to handle its MouseUp event. In that event, you can HitTest the click location and watch for this to indicate HitTestInfo.Nowhere. For example:

Private Sub myDataGridView_MouseUp(ByVal sender as Object, ByVal e as System.Windows.Forms.MouseEventArgs)
    ''# See if the left mouse button was clicked
    If e.Button = MouseButtons.Left Then
        ''# Check the HitTest information for this click location
        If myDataGridView.HitTest(e.X, e.Y) = DataGridView.HitTestInfo.Nowhere Then
            myDataGridView.ClearSelection()
            myDataGridView.CurrentCell = Nothing
        End If
    End If
End Sub

Of course, you could also subclass the existing DataGridView control to combine all of this functionality into a single custom control. You'll need to override its OnMouseUp method similar to the way shown above. I also like to provide a public DeselectAll method for convenience that both calls the ClearSelection method and sets the CurrentCell property to Nothing.

(Code samples are all arbitrarily in VB.NET because the question doesn't specify a language—apologies if this is not your native dialect.)

First go to your control panel , select Date , time and Number Format . Now select English(United Kingdom) from the drop down list.

Make sure the shor date field is equal to 'dd/mm/yyyy'. Press Apply. Now go to SSRS and right click on the report in the empty space and select properties.

If you are using visual studio then set Language property equal to =User!Language.

If you are using Report Builder then Language property will appear in Localization section.

I have Done through git bash:

(use "git checkout -- <file>..." to discard changes in working directory)

1. Git status. [So we have seen one file wad modified.]
2. git checkout -- index.html [i have changed in index.html file :
3. git status [now those changes was removed]

Here is how you to do it automatically on save: https://coderwall.com/p/zvyg7a/convert-tabs-to-spaces-on-file-save

Unfortunately the package is not working when you install it from the Package Manager.

Just Cast date_field as date

SELECT * FROM `objects` 
WHERE (cast(date_field as date) BETWEEN '2010-09-29' AND 
'2010-01-30' )

I had a problem with sending a request with multiple parameters.

I've solved it by sending a class, with the old parameters as properties.

<form action="http://localhost:12345/api/controller/method" method="post">
    <input type="hidden" name="name1" value="value1" />
    <input type="hidden" name="name2" value="value2" />
    <input type="submit" name="submit" value="Submit" />
</form>

Model class:

public class Model {
    public string Name1 { get; set; }
    public string Name2 { get; set; }
}

Controller:

public void method(Model m) {
    string name = m.Name1;
}

Have a look at this

for outputing from mongo shell to file. There is no support for outputing csv from mongos shell. You would have to write the javascript yourself or use one of the many converters available. Google "convert json to csv" for example.

    $restore = $this->createElement('submit', 'restore', array(
        'label' => 'FILE_RESTORE',
        'class' => 'restore btn btn-small btn-primary',
        'attribs' => array(
            'onClick' => 'restoreCheck();return false;'
        )
    ));

Watch this video, I had the same question. He shows you how to debug the service as well.

Here are his instructions using the basic C# Windows Service template in Visual Studio 2010/2012.

You add this to the Service1.cs file:

public void onDebug()
{
    OnStart(null);
}

You change your Main() to call your service this way if you are in the DEBUG Active Solution Configuration.

static void Main()
{
    #if DEBUG
    //While debugging this section is used.
    Service1 myService = new Service1();
    myService.onDebug();
    System.Threading.Thread.Sleep(System.Threading.Timeout.Infinite);

    #else
    //In Release this section is used. This is the "normal" way.
    ServiceBase[] ServicesToRun;
    ServicesToRun = new ServiceBase[] 
    { 
        new Service1() 
    };
    ServiceBase.Run(ServicesToRun);
    #endif
}

Keep in mind that while this is an awesome way to debug your service. It doesn't call OnStop() unless you explicitly call it similar to the way we called OnStart(null) in the onDebug() function.

u can call event function like (focusout) or (blur) then u put your code

<div tabindex=0 (blur)="outsideClick()">raw data </div>
 

 outsideClick() {
  alert('put your condition here');
   }

Yes, you can add a UNIQUE constraint after the fact. However, if you have non-unique entries in your table Postgres will complain about it until you correct them.

Keep it simple!

An AsyncTask is background task which runs in the background thread. It takes an Input, performs Progress and gives Output.

ie AsyncTask<Input,Progress,Output>.

In my opinion the main source of confusion comes when we try to memorize the parameters in the AsyncTask.
The key is Don't memorize.
If you can visualize what your task really needs to do then writing the AsyncTask with the correct signature would be a piece of cake.
Just figure out what your Input, Progress and Output are and you will be good to go.

For example:

Heart of the AsyncTask!

doInBackgound() method is the most important method in an AsyncTask because

• Only this method runs in the background thread and publish data to UI thread.
• Its signature changes with the AsyncTask parameters.

So lets see the relationship

doInBackground() and onPostExecute(),onProgressUpdate() are also related

Show me the code
So how will I write the code for DownloadTask?

DownloadTask extends AsyncTask<String,Integer,String>{

      @Override
      public void onPreExecute()
      {}

      @Override
      public String doInbackGround(String... params)
      {
               // Download code
               int downloadPerc = // calculate that
               publish(downloadPerc);

               return "Download Success";
      }

      @Override
      public void onPostExecute(String result)
      {
          super.onPostExecute(result);
      }

      @Override
      public void onProgressUpdate(Integer... params)
      {
             // show in spinner, access UI elements
      }

}

How will you run this Task

new DownLoadTask().execute("Paradise.mp3");

I would first make the to-be-merged branch as clean as possible. Run your tests, make sure the state is as you want it. Clean up the new commits by git squash.

Besides KingCrunches answer, I suggest to use

git checkout master
git pull origin master
git merge --squash test
git commit
git push origin master

You might have made many commits in the other branch, which should only be one commit in the master branch. To keep the commit history as clean as possible, you might want to squash all your commits from the test branch into one commit in the master branch (see also: Git: To squash or not to squash?). Then you can also rewrite the commit message to something very expressive. Something that is easy to read and understand, without digging into the code.

edit: You might be interested in

• In git, what is the difference between merge --squash and rebase?
• Merging vs. Rebasing
• How to Rebase a Pull Request

So on GitHub, I end up doing the following for a feature branch mybranch:

Get the latest from origin

$ git checkout master
$ git pull origin master

Find the merge base hash:

$ git merge-base mybranch master
c193ea5e11f5699ae1f58b5b7029d1097395196f

$ git checkout mybranch
$ git rebase -i c193ea5e11f5699ae1f58b5b7029d1097395196f

Now make sure only the first is pick, the rest is s:

pick 00f1e76 Add first draft of the Pflichtenheft
s d1c84b6 Update to two class problem
s 7486cd8 Explain steps better

Next choose a very good commit message and push to GitHub. Make the pull request then.

After the merge of the pull request, you can delete it locally:

$ git branch -d mybranch

and on GitHub

$ git push origin :mybranch

If you set the style table-layout: fixed; on your table, you can override the browser's automatic column resizing. The browser will then set column widths based on the width of cells in the first row of the table. Change your <thead> to <caption> and remove the <td> inside of it, and then set fixed widths for the cells in <tbody>.

So this is a little bit of a subtle point, because while Python only passes variables by value, every variable in Python is a reference. If you want to be able to change your values with a function call, what you need is a mutable object. For example:

l = [0]

def set_3(x):
    x[0] = 3

set_3(l)
print(l[0])

In the above code, the function modifies the contents of a List object (which is mutable), and so the output is 3 instead of 0.

I write this answer only to illustrate what 'by value' means in Python. The above code is bad style, and if you really want to mutate your values you should write a class and call methods within that class, as MPX suggests.

You need to store the psftp script (lines from open to bye) into a separate file and pass that to psftp using -b switch:

cd "C:\Program Files (x86)\PuTTY"
psftp -b "C:\path\to\script\script.txt"

Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-option-b

EDIT: For username+password: As you cannot use psftp commands in a batch file, for the same reason, you cannot specify the username and the password as psftp commands. These are inputs to the open command. While you can specify the username with the open command (open <user>@<IP>), you cannot specify the password this way. This can be done on a psftp command line only. Then it's probably cleaner to do all on the command-line:

cd "C:\Program Files (x86)\PuTTY"
psftp -b script.txt <user>@<IP> -pw <PW>

And remove the open, <user> and <PW> lines from your script.txt.

Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-starting
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter3.html#using-cmdline-pw

What you are doing atm is that you run psftp without any parameter or commands. Once you exit it (like by typing bye), your batch file continues trying to run open command (and others), what Windows shell obviously does not understand.

If you really want to keep everything in one file (the batch file), you can write commands to psftp standard input, like:

(
    echo cd ...
    echo lcd ...
    echo put log.sh
) | psftp -b script.txt <user>@<IP> -pw <PW>

This works on Windows and python 3.6

import time
for x in range(10):
    time.sleep(0.5)
    print(str(x)+'\r',end='')

You can use the root.configure(background='your colour') example:- import tkinter root=tkiner.Tk() root.configure(background='pink')

Make the submit button the main image you are using. So the form tags would come first then submit button which is your only image so the image is your clickable image form. Then just make sure to put whatever you are passing before the submit button code.

BEGIN
  FOR r IN (select sid,serial# from v$session where username='user')
  LOOP
      EXECUTE IMMEDIATE 'alter system kill session ''' || r.sid  || ',' || r.serial# || '''';
  END LOOP;
END;
/

It works for me.

You can use pd.to_datetime() to convert to a datetime object. It takes a format parameter, but in your case I don't think you need it.

>>> import pandas as pd
>>> df = pd.DataFrame( {'Symbol':['A','A','A'] ,
    'Date':['02/20/2015','01/15/2016','08/21/2015']})
>>> df
         Date Symbol
0  02/20/2015      A
1  01/15/2016      A
2  08/21/2015      A
>>> df['Date'] =pd.to_datetime(df.Date)
>>> df.sort('Date') # This now sorts in date order
        Date Symbol
0 2015-02-20      A
2 2015-08-21      A
1 2016-01-15      A

For future search, you can change the sort statement:

>>> df.sort_values(by='Date') # This now sorts in date order
        Date Symbol
0 2015-02-20      A
2 2015-08-21      A
1 2016-01-15      A

Use sudo pico /etc/paths inside the terminal window and change the entries to the one you want to remove, then open a new terminal session.

When you use addEventListener, this will be bound automatically. So if you want a reference to the element on which the event handler is installed, just use this from within your function:

productLineSelect.addEventListener('change',getSelection,false);

function getSelection(){
    var value = sel.options[this.selectedIndex].value;
    alert(value);
}

If you want to pass in some other argument from the context where you call addEventListener, you can use a closure, like this:

productLineSelect.addEventListener('change', function(){ 
    // pass in `this` (the element), and someOtherVar
    getSelection(this, someOtherVar); 
},false);

function getSelection(sel, someOtherVar){
    var value = sel.options[sel.selectedIndex].value;
    alert(value);
    alert(someOtherVar);
}

I depends heavily on which number formats you aim to support, and how strict you want to enforce number grouping, use of whitespace and other separators etc....

Take a look at this similar question to get some ideas.

Then there is E.164 which is a numbering standard recommendation from ITU-T

Based on the List Members Instance docs, the easiest way is to use a PUT request which according to the docs either "adds a new list member or updates the member if the email already exists on the list".

Furthermore apikey is definitely not part of the json schema and there's no point in including it in your json request.

Also, as noted in @TooMuchPete's comment, you can use CURLOPT_USERPWD for basic http auth as illustrated in below.

I'm using the following function to add and update list members. You may need to include a slightly different set of merge_fields depending on your list parameters.

$data = [
    'email'     => '[email protected]',
    'status'    => 'subscribed',
    'firstname' => 'john',
    'lastname'  => 'doe'
];

syncMailchimp($data);

function syncMailchimp($data) {
    $apiKey = 'your api key';
    $listId = 'your list id';

    $memberId = md5(strtolower($data['email']));
    $dataCenter = substr($apiKey,strpos($apiKey,'-')+1);
    $url = 'https://' . $dataCenter . '.api.mailchimp.com/3.0/lists/' . $listId . '/members/' . $memberId;

    $json = json_encode([
        'email_address' => $data['email'],
        'status'        => $data['status'], // "subscribed","unsubscribed","cleaned","pending"
        'merge_fields'  => [
            'FNAME'     => $data['firstname'],
            'LNAME'     => $data['lastname']
        ]
    ]);

    $ch = curl_init($url);

    curl_setopt($ch, CURLOPT_USERPWD, 'user:' . $apiKey);
    curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $json);                                                                                                                 

    $result = curl_exec($ch);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);

    return $httpCode;
}

Use this script for redis >=5:

#!/bin/bash
redis-cli keys "*" > keys.txt
cat keys.txt | awk '{ printf "type %s\n", $1 }' | redis-cli > types.txt
paste -d'|' keys.txt types.txt | awk -F\| '
   $2 == "string"               { printf "echo \"KEY %s %s\"\nget %s\n", $1, $2, $1 }
   $2 == "list" || $2 == "set"  { printf "echo \"KEY %s %s\"\nsort %s by nosort\n", $1, $2, $1 }
   $2 == "hash"                 { printf "echo \"KEY %s %s\"\nhgetall %s\n", $1, $2, $1 }
   $2 == "zset"                 { printf "echo \"KEY %s %s\"\nzrange %s 0 -1 withscores\n", $1, $2,$1 }

For working with UTC timezones:

time_stamp = calendar.timegm(dt.timetuple())

datetime.utcfromtimestamp(time_stamp)

b''.fromhex('7061756c')

use it without delimiter

This one is quite simple and does not require a delegate as you say.

resultString = Regex.Replace(subjectString, 
     @"(?im)^[{(]?[0-9A-F]{8}[-]?(?:[0-9A-F]{4}[-]?){3}[0-9A-F]{12}[)}]?$", 
     "'$0'");

This matches the following styles, which are all equivalent and acceptable formats for a GUID.

ca761232ed4211cebacd00aa0057b223
CA761232-ED42-11CE-BACD-00AA0057B223
{CA761232-ED42-11CE-BACD-00AA0057B223}
(CA761232-ED42-11CE-BACD-00AA0057B223)

Update 1

@NonStatic makes the point in the comments that the above regex will match false positives which have a wrong closing delimiter.

This can be avoided by regex conditionals which are broadly supported.

Conditionals are supported by the JGsoft engine, Perl, PCRE, Python, and the .NET framework. Ruby supports them starting with version 2.0. Languages such as Delphi, PHP, and R that have regex features based on PCRE also support conditionals. (source http://www.regular-expressions.info/conditional.html)

The regex that follows Will match

{123}
(123)
123

And will not match

{123)
(123}
{123
(123
123}
123)

Regex:

^({)?(\()?\d+(?(1)})(?(2)\))$

The solutions is simplified to match only numbers to show in a more clear way what is required if needed.

Be sure to supply the exact same path as when you set it, i.e.

Setting:

$.cookie('foo','bar', {path: '/'});

Removing:

$.cookie('foo', null, {path: '/'});

Note that

$.cookie('foo', null); 

will NOT work, since it is actually not the same cookie.

Hope that helps. The same goes for the other options in the hash

It was windows permission issue i move the folder thats it inherit wrong permissions. When i move to wwwroot folder and add permission to iis user it start working fine.

Subscript out of Range error occurs when you try to reference an Index for a collection that is invalid.

Most likely, the index in Windows does not actually include .xls. The index for the window should be the same as the name of the workbook displayed in the title bar of Excel.

As a guess, I would try using this:

Windows("Data Sheet - " & ComboBox_Month.Value & " " & TextBox_Year.Value).Activate

I did some experimentation with strings like '', ' ', '\n', etc. I want isNotWhitespace to be True if and only if the variable foo is a string with at least one non-whitespace character. I'm using Python 3.6. Here's what I ended up with:

isWhitespace = str is type(foo) and not foo.strip()
isNotWhitespace = str is type(foo) and not not foo.strip()

Wrap this in a method definition if desired.

You should add the ngDefaultControl attribute to your input like this:

<md-input
    [(ngModel)]="recipient"
    name="recipient"
    placeholder="Name"
    class="col-sm-4"
    (blur)="addRecipient(recipient)"
    ngDefaultControl>
</md-input>

Taken from comments in this post:

angular2 rc.5 custom input, No value accessor for form control with unspecified name

Note: For later versions of @angular/material:

Nowadays you should instead write:

<md-input-container>
    <input
        mdInput
        [(ngModel)]="recipient"
        name="recipient"
        placeholder="Name"
        (blur)="addRecipient(recipient)">
</md-input-container>

all answers so far use some version of forEach, iterating over all collection elements client-side.

However, you could use MongoDB's server-side processing by using aggregate pipeline and $out stage as :

the $out stage atomically replaces the existing collection with the new results collection.

example:

db.documents.aggregate([
         {
            $project: {
               _id: 1,
               numberField: { $substr: ['$numberField', 0, -1] },
               otherField: 1,
               differentField: 1,
               anotherfield: 1,
               needolistAllFieldsHere: 1
            },
         },
         {
            $out: 'documents',
         },
      ]);

Use the following line on the top of the PHP page where you're using $_SERVER['REQUEST_URI']. This will resolve your issue.

$_SERVER['REQUEST_URI'] = $_SERVER['PHP_SELF'] . '?' . $_SERVER['argv'][0];

You can specify the shell to be used by the remote host locally.

echo 'echo "Bash version: ${BASH_VERSION}"' | ssh -q localhost bash

And be careful to (single-)quote the variables you wish to be expanded by the remote host; otherwise variable expansion will be done by your local shell!

# example for local / remote variable expansion
{
echo "[[ $- == *i* ]] && echo 'Interactive' || echo 'Not interactive'" | 
    ssh -q localhost bash
echo '[[ $- == *i* ]] && echo "Interactive" || echo "Not interactive"' | 
    ssh -q localhost bash
}

So, to check if a certain file exists on the remote host you can do the following:

host='localhost'  # localhost as test case
file='~/.bash_history'
if `echo 'test -f '"${file}"' && exit 0 || exit 1' | ssh -q "${host}" sh`; then
#if `echo '[[ -f '"${file}"' ]] && exit 0 || exit 1' | ssh -q "${host}" bash`; then
   echo exists
else
   echo does not exist
fi

Some important facts were not given in other answers:

"async await" is more complex at CIL level and thus costs memory and CPU time.

Any task can be canceled if the waiting time is unacceptable.

In the case "async await" we do not have a handler for such a task to cancel it or monitoring it.

Using Task is more flexible then "async await".

Any sync functionality can by wrapped by async.

public async Task<ActionResult> DoAsync(long id) 
{ 
    return await Task.Run(() => { return DoSync(id); } ); 
} 

"async await" generate many problems. We do not now is await statement will be reached without runtime and context debugging. If first await not reached everything is blocked. Some times even await seems to be reached still everything is blocked:

https://github.com/dotnet/runtime/issues/36063

I do not see why I'm must live with the code duplication for sync and async method or using hacks.

Conclusion: Create Task manually and control them is much better. Handler to Task give more control. We can monitor Tasks and manage them:

Sorry for my english.

You can use Date.parse(), but the input formats that it accepts are implementation-dependent. However, if you can convert the date to ISO format (YYYY-MM-DD), most implementations should understand it.

Try -

Or rename the folder as AmberCRO-SOP and write it as -

See my answer here if you're having this problem while running unit tests. Answer copied below:

Building upon Sébastien's answer, I added a pre-build step to my test project to automatically kill any vstest.* executables still running. The following pre-build command worked for me:

taskkill /f /im vstest.*
exit 0

The exit 0 command is at the end to prevent build failure when there are no vstest.* executables running.

public const int NUMBER = 9;

You'd need to put it in a class somewhere, and the usage would be ClassName.NUMBER

I had a similar query and a similar issue.

SELECT
    *
FROM
    Users ru
    LEFT OUTER JOIN 
    (
        SELECT ru1.UserID, COUNT(*)
        FROM Referral r
        LEFT OUTER JOIN Users ru1 ON r.ReferredUserId = ru1.UserID
        GROUP BY ru1.UserID
    ) ReferralTotalCount ON ru.UserID = ReferralTotalCount.UserID

I found that SQL Server was choking on the COUNT(*) column, and was giving me the error No column was specified for column 2.

Putting an alias on the COUNT(*) column fixed the issue.

  SELECT
        *
    FROM
        Users ru
        LEFT OUTER JOIN 
        (
            SELECT ru1.UserID, COUNT(*) AS -->MyCount<--
            FROM Referral r
            LEFT OUTER JOIN Users ru1 ON r.ReferredUserId = ru1.UserID
            GROUP BY ru1.UserID
        ) ReferralTotalCount ON ru.UserID = ReferralTotalCount.UserID

Aside: Note that the standard LINQ operators (as per the earlier example) don't change the existing list - list.OrderBy(...).ToList() will create a new list based on the re-ordered sequence. It is pretty easy, however, to create an extension method that allows you to use lambdas with List<T>.Sort:

static void Sort<TSource, TValue>(this List<TSource> list,
    Func<TSource, TValue> selector)
{
    var comparer = Comparer<TValue>.Default;
    list.Sort((x,y) => comparer.Compare(selector(x), selector(y)));
}

static void SortDescending<TSource, TValue>(this List<TSource> list,
    Func<TSource, TValue> selector)
{
    var comparer = Comparer<TValue>.Default;
    list.Sort((x,y) => comparer.Compare(selector(y), selector(x)));
}

Then you can use:

list.Sort(x=>x.SomeProp); // etc

This updates the existing list in the same way that List<T>.Sort usually does.

Combining and organizing all the current answers into one answer, then adding my own research:

Brief summary of Microsoft gadget development:

What are they written in? Windows Vista/Seven gadgets are developed in a mix of XML, HTML, CSS, and some IE scripting language. It is also possible to use C# with the latest release of Script#.

How are they packaged/deployed? The actual gadgets are stored in *.gadget files, which are simply the text source files listed above compressed into a single zip file.

Useful references for gadget development:

where do I start? Good introductory references to Windows Vista/Seven gadget development:

• Developing Gadgets for the Windows Sidebar
• Vista Gadgets Introductory tutorial from I-Programmer
• Authoring Sidebar Gadgets in C#
• Developing a Gadget for Windows Sidebar Part 1: The Basics Official MSDN tutorial.

If you are willing to use offline resources, this book appears to be an excellent resource:

• Creating Vista Gadgets: Using HTML, CSS and JavaScript with Examples in RSS, Ajax, ActiveX (COM) and Silverlight
• blog related to book: http://www.innovatewithgadgets.com/

What do I need to know? Some other useful references; not necessarily instructional

• Windows Sidebar (Official MSDN documentation)
• related Stack Overflow question: C# tutorial to write gadgets

Update: Well, this has proven to be a popular answer~ Sharing my own recent experience with Windows 7 gadget development:

Perhaps the easiest way to get started with Windows 7 gadget development is to modify a gadget that has already been developed. I recently did this myself because I wanted a larger clock gadget. Unable to find any, I tinkered with a copy of the standard Windows clock gadget until it was twice as large. I recommend starting with the clock gadget because it is fairly small and well-written. Here is the process I used:

1. Locate the gadget you wish to modify. They are located in several different places. Search for folders named *.gadget. Example: C:\Program Files\Windows Sidebar\Gadgets\Clock.Gadget\
2. Make a copy of this folder (installed gadgets are not wrapped in zip files.)
3. Rename some key parts:
   1. The folder name
   2. The name inside the gadget.xml file. It looks like:<name>Clock</name> This is the name that will be displayed in the "Gadgets Gallery" window.
4. Zip up the entire *.gadget directory.
5. Change the file extension from "zip" to "gadget" (Probably just need to remove the ".zip" extension.)
6. Install your new copy of the gadget by double clicking the new *.gadget file. You can now add your gadget like any other gadget (right click desktop->Gadgets)
7. Locate where this gadget is installed (probably to %LOCALAPPDATA%\Microsoft\Windows Sidebar\)
8. Modify the files in this directory. The gadget is very similar to a web page: HTML, CSS, JS, and image files. The gadget.xml file specifies which file is opened as the "index" page for the gadget.
9. After you save the changes, view the results by installing a new instance of the gadget. You can also debug the JavaScript (The rest of that article is pretty informative, too).

Maybe try this? It seems the problem is solved after remove all the handlers in my case.

for handler in logging.root.handlers[:]:
    logging.root.removeHandler(handler)

logging.basicConfig(filename='output.log', level=logging.INFO)

It means that the value type in question is a nullable type

Nullable types are instances of the System.Nullable struct. A nullable type can represent the correct range of values for its underlying value type, plus an additional null value. For example, a Nullable<Int32>, pronounced "Nullable of Int32," can be assigned any value from -2147483648 to 2147483647, or it can be assigned the null value. A Nullable<bool> can be assigned the values true, false, or null. The ability to assign null to numeric and Boolean types is especially useful when you are dealing with databases and other data types that contain elements that may not be assigned a value. For example, a Boolean field in a database can store the values true or false, or it may be undefined.

class NullableExample
{
  static void Main()
  {
      int? num = null;

      // Is the HasValue property true?
      if (num.HasValue)
      {
          System.Console.WriteLine("num = " + num.Value);
      }
      else
      {
          System.Console.WriteLine("num = Null");
      }

      // y is set to zero
      int y = num.GetValueOrDefault();

      // num.Value throws an InvalidOperationException if num.HasValue is false
      try
      {
          y = num.Value;
      }
      catch (System.InvalidOperationException e)
      {
          System.Console.WriteLine(e.Message);
      }
  }
}

You can use:

f.Controls[name];

Where f is your form variable. That gives you the control with name name.

Still an old one, but answer from Lee did not give me the group.Key as result. Therefore, I am using the following statement to group a list and return a grouped list:

public IOrderedEnumerable<IGrouping<string, User>> groupedCustomerList;

groupedCustomerList =
        from User in userList
        group User by User.GroupID into newGroup
        orderby newGroup.Key
        select newGroup;

Each group now has a key, but also contains an IGrouping which is a collection that allows you to iterate over the members of the group.

Use the following code

$("#modal").trigger('click');

What happens if the size of array is unknown? Or array should be dynamically created and populated? Alternative solution which worked for me is to use class with static 2d array variable which in case of non-existence of index in array will initiate it:

function _a(x,y,val){
    // return depending on parameters
    switch(arguments.length){
        case 0: return _a.a;
        case 1: return _a.a[x];
        case 2: return _a.a[x][y];
    }

    // declare array if wasn't declared yet
    if(typeof _a.a[x] == 'undefined')
        _a.a[x] = [];

    _a.a[x][y] = val;
}
// declare static empty variable
_a.a = [];

The syntax will be:

_a(1,1,2); // populates [1][1] with value 2
_a(1,1);   // 2 or alternative syntax _a.a[1][1]
_a(1);     // [undefined × 1, 2]
_a.a;      // [undefined × 1, Array[2]]
_a.a.length

Building off of deepee1 and this, here's how to accept a class name in a string, and then use it to read and write to a database with LINQ. I use "dynamic" instead of deepee1's casting because it allows me to assign properties, which allows us to dynamically select and operate on any table we want.

Type tableType = Assembly.GetExecutingAssembly().GetType("NameSpace.TableName");
ITable itable = dbcontext.GetTable(tableType);

//prints contents of the table
foreach (object y in itable) {
    string value = (string)y.GetType().GetProperty("ColumnName").GetValue(y, null);
    Console.WriteLine(value);
}

//inserting into a table
dynamic tableClass = Activator.CreateInstance(tableType);
//Alternative to using tableType, using Tony's tips
dynamic tableClass = Activator.CreateInstance(null, "NameSpace.TableName").Unwrap();
tableClass.Word = userParameter;
itable.InsertOnSubmit(tableClass);
dbcontext.SubmitChanges();

//sql equivalent
dbcontext.ExecuteCommand("INSERT INTO [TableNme]([ColumnName]) VALUES ({0})", userParameter);

Use each_with_index when you need both.

ary.each_with_index { |val, idx| # ...

Your sample code seems to be OK. Thus, the root problem needs to be dug up somehow. Let's eliminate chance for typos in the script. First off, make sure you put Set-Strictmode -Version 2.0 in the beginning of your script. This will help you to catch misspelled variable names. Like so,

# Test.ps1
set-strictmode -version 2.0 # Comment this line and no error will be reported.
$foo = "bar"
set-content -path ./test.txt -value $fo # Error! Should be "$foo"

PS C:\temp> .\test.ps1
The variable '$fo' cannot be retrieved because it has not been set.
At C:\temp\test.ps1:3 char:40
+ set-content -path ./test.txt -value $fo <<<<
    + CategoryInfo          : InvalidOperation: (fo:Token) [], RuntimeException
    + FullyQualifiedErrorId : VariableIsUndefined

The next part about question marks sounds like you have a problem with Unicode. What's the output when you type the file with Powershell like so,

$file = "\\server\share\file.txt"
cat $file

My Experience with this issue using WPF C# coping to clipboard and System.Threading.ThreadStateException is here with my code that worked correctly with all browsers:

Thread thread = new Thread(() => Clipboard.SetText("String to be copied to clipboard"));
thread.SetApartmentState(ApartmentState.STA); //Set the thread to STA
thread.Start(); 
thread.Join();

But this works only on localhost, so don't try this on a server, as it's not going to work.

On server-side, I did it by using zeroclipboard. The only way, after a lot of research.

If you use ASP.NET and IISExpress go to "C:\Users\\Documents\IISExpress\config\applicationhost.config", search for your Project and look if you have a faulty virtualDirectory entry.

In addition to what Angular University said above you may want to use @Import to aggregate @Configuration classes to the other class (AuthenticationController in my case) :

@Import(SecurityConfig.class)
@RestController
public class AuthenticationController {
@Autowired
private AuthenticationManager authenticationManager;
//some logic
}

Spring doc about Aggregating @Configuration classes with @Import: link

Add .idea and *.iml to .gitignore, you don't need those files to successfully import and compile the project.

The issue was magically resolved for me by removing .NET 4.5, and replacing it with .NET 4.0. I then had to repair Visual Studio 2010 - it being corrupted along the way somehow.

I had previously installed, and then un-installed, Visual Studio 2012 - which may be related to the issue.

Numbers

When sorting numbers, you can use the compact comparison:

var numericArray: number[] = [2, 3, 4, 1, 5, 8, 11];

var sortedArray: number[] = numericArray.sort((n1,n2) => n1 - n2);

i.e. - rather than <.

Other Types

If you are comparing anything else, you'll need to convert the comparison into a number.

var stringArray: string[] = ['AB', 'Z', 'A', 'AC'];

var sortedArray: string[] = stringArray.sort((n1,n2) => {
    if (n1 > n2) {
        return 1;
    }

    if (n1 < n2) {
        return -1;
    }

    return 0;
});

Objects

For objects, you can sort based on a property, bear in mind the above information about being able to short-hand number types. The below example works irrespective of the type.

var objectArray: { age: number; }[] = [{ age: 10}, { age: 1 }, {age: 5}];

var sortedArray: { age: number; }[] = objectArray.sort((n1,n2) => {
    if (n1.age > n2.age) {
        return 1;
    }

    if (n1.age < n2.age) {
        return -1;
    }

    return 0;
});

If you want to bind custom logic to resize event, nowadays you may start using ResizeObserver browser API for the bounding box of an SVGElement.
This will also handle the case when container is resized because of the nearby elements size change.
There is a polyfill for broader browser support.

This is how it may work in UI component:

function redrawGraph(container, { width, height }) {_x000D_
  d3_x000D_
    .select(container)_x000D_
    .select('svg')_x000D_
    .attr('height', height)_x000D_
    .attr('width', width)_x000D_
    .select('rect')_x000D_
    .attr('height', height)_x000D_
    .attr('width', width);_x000D_
}_x000D_
_x000D_
// Setup observer in constructor_x000D_
const resizeObserver = new ResizeObserver((entries, observer) => {_x000D_
  for (const entry of entries) {_x000D_
    // on resize logic specific to this component_x000D_
    redrawGraph(entry.target, entry.contentRect);_x000D_
  }_x000D_
})_x000D_
_x000D_
// Observe the container_x000D_
const container = document.querySelector('.graph-container');_x000D_
resizeObserver.observe(container)

.graph-container {_x000D_
  height: 75vh;_x000D_
  width: 75vw;_x000D_
}_x000D_
_x000D_
.graph-container svg rect {_x000D_
  fill: gold;_x000D_
  stroke: steelblue;_x000D_
  stroke-width: 3px;_x000D_
}

<script src="https://unpkg.com/[email protected]/dist/ResizeObserver.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/d3/5.7.0/d3.min.js"></script>_x000D_
_x000D_
<figure class="graph-container">_x000D_
  <svg width="100" height="100">_x000D_
    <rect x="0" y="0" width="100" height="100" />_x000D_
  </svg>_x000D_
</figure>

// unobserve in component destroy method
this.resizeObserver.disconnect()

You could can use git rebase to rewrite the commit history. This can be potentially destructive to your changes, so use with care.

First commit your "amend" change as a normal commit. Then do an interactive rebase starting on the parent of your oldest commit

git rebase -i 47175e84c2cb7e47520f7dde824718eae3624550^

This will fire up your editor with all commits. Reorder them so your "amend" commit comes below the one you want to amend. Then replace the first word on the line with the "amend" commit with s which will combine (s quash) it with the commit before. Save and exit your editor and follow the instructions.

DECLARE @MyFloat [float]

SET @MyFloat = 1000109360.050

SELECT REPLACE (RTRIM (REPLACE (REPLACE (RTRIM ((REPLACE (CAST (CAST (@MyFloat AS DECIMAL (38 ,18 )) AS VARCHAR( max)), '0' , ' '))), ' ' , '0'), '.', ' ')), ' ','.')

Google brought me here but... The examples provided work if the dropdown menu is overlaping (at least by 1px) with its parent when show. If not, it loses focus and nothing works as intended.

Here is a working solution with jQuery and Bootstrap 4.5.2 :

$('li.nav-item').mouseenter(function (e) {

        e.stopImmediatePropagation();

        if ($(this).hasClass('dropdown')) {

            // target element containing dropdowns, show it
            $(this).addClass('show');
            $(this).find('.dropdown-menu').addClass('show');

            // Close dropdown on mouseleave
            $('.dropdown-menu').mouseleave(function (e) {
                e.stopImmediatePropagation();
                $(this).removeClass('show');
            });

            // If you have a prenav above, this clears open dropdowns (since you probably will hover the nav-item going up and it will reopen its dropdown otherwise)
            $('#prenav').off().mouseenter(function (e) {
                e.stopImmediatePropagation();
                $('.dropdown-menu').removeClass('show');
            });

        } else {
            // unset open dropdowns if hover is on simple nav element
            $('.dropdown-menu').removeClass('show');
        }
    });

SELECT tab.*,
    row_number() OVER () as rnum
  FROM tab;

Here's the relevant section in the docs.

P.S. This, in fact, fully matches the answer in the referenced question.

Try readystatechange

document.addEventListener('readystatechange', () => {    
  if (document.readyState == 'complete') codeAddress();
});

where states are:

• loading - the document is loading (no fired in snippet)
• interactive - the document is parsed, fired before DOMContentLoaded
• complete - the document and resources are loaded, fired before window.onload

<script>_x000D_
  document.addEventListener("DOMContentLoaded", () => {_x000D_
    mydiv.innerHTML += `DOMContentLoaded (timestamp: ${Date.now()})</br>`;_x000D_
  });_x000D_
  _x000D_
  window.onload = () => {_x000D_
    mydiv.innerHTML += `window.onload (timestamp: ${Date.now()}) </br>` ;_x000D_
  } ;_x000D_
_x000D_
  document.addEventListener('readystatechange', () => {_x000D_
    mydiv.innerHTML += `ReadyState: ${document.readyState}  (timestamp: ${Date.now()})</br>`;_x000D_
    _x000D_
    if (document.readyState == 'complete') codeAddress();_x000D_
  });_x000D_
_x000D_
  function codeAddress() {_x000D_
    mydiv.style.color = 'red';_x000D_
  }_x000D_
</script>_x000D_
_x000D_
<div id='mydiv'></div>

use RelativeLayout inside LinearLayout

example:

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent">
            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_centerVertical="true"
                android:text="Status"/>
        </RelativeLayout>
</LinearLayout>

I need to do this frequently, so I use this:

var loadJS = function(url, implementationCode, location){
    //url is URL of external file, implementationCode is the code
    //to be called from the file, location is the location to 
    //insert the <script> element

    var scriptTag = document.createElement('script');
    scriptTag.src = url;

    scriptTag.onload = implementationCode;
    scriptTag.onreadystatechange = implementationCode;

    location.appendChild(scriptTag);
};
var yourCodeToBeCalled = function(){
//your code goes here
}
loadJS('yourcode.js', yourCodeToBeCalled, document.body);

For more information, see this site How do I include a JavaScript file in another JavaScript file?, which is the source of my function idea.

Simply use the following command,

For Export:

mysqldump -u [user] -p [db_name] | gzip > [filename_to_compress.sql.gz] 

For Import:

gunzip < [compressed_filename.sql.gz]  | mysql -u [user] -p[password] [databasename] 

Note: There is no space between the keyword '-p' and your password.

Simple: Just create a (nested) PHP array and call json_encode on it. Numeric arrays translate into JSON lists ([]), associative arrays and PHP objects translate into objects ({}). Example:

$a = array(
        array('foo' => 'bar'),
        array('foo' => 'baz'));
$json = json_encode($a);

Gives you:

[{"foo":"bar"},{"foo":"baz"}]

. is a shorthand for the current directory and is used in Linux and Unix to execute a compiled program in the current directory. That is why you don't see this used in Web Development much except by open source, non-Windows frameworks like Google Angular which was written by people stuck on open source platforms.

./ also resolves to the current directory and is atypical in Web but supported as a path in some open source frameworks. Because it resolves the same as no path to the current file directory its not used. Example: ./image.jpg = image.jpg. Again, this is a relic of Unix operating systems that need path resolutions like this to run executables and resolve paths for security reasons. Its not a typical web path. That is why this syntax is redundant.

../ is a traditional web path that goes one directory up

/ is the ROOT of your website

These path resolutions below are true...

./folder= folder this is always true in web path resolution

./file.html = file.html this is always true in web path resolution

./ = {no path} an empty path is the same as ./ in the web world

{no path} = / an empty path is the same as the web root if your file is in the root directory

./ = / ONLY if you are in the root folder

../ = / ONLY if you are one folder below the web root

you could use setBackgroundResource() instead i.e. relativeLayout.setBackgroundResource(R.drawable.back);

this works for me.

You get the error because order[1] is undefined.

That error message means that somewhere in your code, an attempt is being made to access a property with some name (here it's "push"), but instead of an object, the base for the reference is actually undefined. Thus, to find the problem, you'd look for code that refers to that property name ("push"), and see what's to the left of it. In this case, the code is

if(parseInt(a[i].daysleft) > 0){ order[1].push(a[i]); }

which means that the code expects order[1] to be an array. It is, however, not an array; it's undefined, so you get the error. Why is it undefined? Well, your code doesn't do anything to make it anything else, based on what's in your question.

Now, if you just want to place a[i] in a particular property of the object, then there's no need to call .push() at all:

var order = [], stack = [];
for(var i=0;i<a.length;i++){
    if(parseInt(a[i].daysleft) == 0){ order[0] = a[i]; }
    if(parseInt(a[i].daysleft) > 0){ order[1] = a[i]; }
    if(parseInt(a[i].daysleft) < 0){ order[2] = a[i]; }
}

After read all Answers I came up with elegant way:

public class MyActivity extends ActionBarActivity {

 Fragment fragment ;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    FragmentManager fm = getSupportFragmentManager();
    fragment = fm.findFragmentByTag("myFragmentTag");
    if (fragment == null) {
        FragmentTransaction ft = fm.beginTransaction();
        fragment =new MyFragment();
        ft.add(android.R.id.content,fragment,"myFragmentTag");
        ft.commit();
    }

}

basically you don't need to add a frameLayout as container of your fragment instead you can add straight the fragment into the android root View container

IMPORTANT: don't use replace fragment as most of the approach shown here, unless you don't mind to lose fragment variable instance state during onrecreation process.

For a bandpass filter, ws is a tuple containing the lower and upper corner frequencies. These represent the digital frequency where the filter response is 3 dB less than the passband.

wp is a tuple containing the stop band digital frequencies. They represent the location where the maximum attenuation begins.

gpass is the maximum attenutation in the passband in dB while gstop is the attentuation in the stopbands.

Say, for example, you wanted to design a filter for a sampling rate of 8000 samples/sec having corner frequencies of 300 and 3100 Hz. The Nyquist frequency is the sample rate divided by two, or in this example, 4000 Hz. The equivalent digital frequency is 1.0. The two corner frequencies are then 300/4000 and 3100/4000.

Now lets say you wanted the stopbands to be down 30 dB +/- 100 Hz from the corner frequencies. Thus, your stopbands would start at 200 and 3200 Hz resulting in the digital frequencies of 200/4000 and 3200/4000.

To create your filter, you'd call buttord as

fs = 8000.0
fso2 = fs/2
N,wn = scipy.signal.buttord(ws=[300/fso2,3100/fso2], wp=[200/fs02,3200/fs02],
   gpass=0.0, gstop=30.0)

The length of the resulting filter will be dependent upon the depth of the stop bands and the steepness of the response curve which is determined by the difference between the corner frequency and stopband frequency.

When you create an initialization of the ResourceBundle, you can do this way also.

For testing and development I have created a properties file under \src with the name prp.properties.

Use this way:

ResourceBundle rb = ResourceBundle.getBundle("prp");

Naming convention and stuff:

http://192.9.162.55/developer/technicalArticles/Intl/ResourceBundles/

I decided to just build controls dictionaries. Harder to maintain, might run faster than the recursive FindControl().

protected void Page_Load(object sender, EventArgs e)
{
  this.BuildControlDics();
}

private void BuildControlDics()
{
  _Divs = new Dictionary<MyEnum, HtmlContainerControl>();
  _Divs.Add(MyEnum.One, this.divOne);
  _Divs.Add(MyEnum.Two, this.divTwo);
  _Divs.Add(MyEnum.Three, this.divThree);

}

And before I get down-thumbs for not answering the OP's question...

Q: Now, my question is that is there any other way/solution to find the nested control in ASP.NET? A: Yes, avoid the need to search for them in the first place. Why search for things you already know are there? Better to build a system allowing reference of known objects.

Here is what worked for me: (I got this answer from https://productforums.google.com/forum/#!topic/chrome/MJjuK65Exkg)

1. Unpin Chrome icon from task bar so it is on the desktop.
2. Right mouse click on said icon and left click on Properties.
3. Click on Shortcuts tab 4A. In Target window, add this exact text: [space]--disable-gpu" 4B. The end of the text string in the Target window should now read: ...chrome.exe" --disable-gpu"
4. Double click on the desktop icon and Chrome should open correctly. If you want, you may pin this icon to the taskbar.
5. Left single click on the "Customize" icon in the top right, which is the 3 horizontal lines icon. Select "Settings" from the list.
6. Select "Show advanced settings..." at the bottom.
7. Deselect "Use hardware acceleration when available."

I had a same problem, and I solved my problem.
First go to config.default.php and change

$cfg['Servers'][$i]['AllowNoPassword'] = false;

to

$cfg['Servers'][$i]['AllowNoPassword'] = true;

You can use the row_number() function for this.

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
            row_number() over (order by (select NULL))
    FROM PM_Ingrediants 
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

If you want to start with the maximum already in the table then do:

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
           coalesce(const.maxs, 0) + row_number() over (order by (select NULL))
    FROM PM_Ingrediants cross join
         (select max(sequence) as maxs from PM_Ingrediants_Arrangement_Temp) const
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

Finally, you can just make the sequence column an auto-incrementing identity column. This saves the need to increment it each time:

create table PM_Ingrediants_Arrangement_Temp ( . . .
    sequence int identity(1, 1) -- and might consider making this a primary key too
    . . .
)

adding a swift 3 option:

cell.layer.borderColor = UIColor (red: 192.0/255.0, green: 192.0/255.0, blue: 197/255.0, alpha: 1.0).cgColor

<ImageView
    android:id="@+id/img"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center" />

One more thing to add to the list as this is the first result that comes up with a google search of 'Error: [$injector:modulerr] angular':

If you have a mismatch between your app name in your 'index'html' and in your main javascript app definition this can also generate this error.

For example if your HTML looks like this:

    </head>
    <body ng-app="myWebSite">

        <!-- My Web Site -->
        <p>About my web site...</p>

        etc ...

And your JavaScript looks like this (i.e has a typo on app name - myWebCite instead of myWebSite):

/** Main AngularJS Web Application */ 
var app = angular.module('myWebCite', [ 'ngRoute' ]); 

/** Configure the Routes */ 
app.config(['$routeProvider', function ($routeProvider) { 
  etc ...

then the 'Error:[$injector:modulerr] angular' error will be generated also.

The above are all excellent answers. I just wanted to add that when there are multiple characters to check against, an if-else might turn out better since you could instead write the following.

// switch on vowels, digits, punctuation, or consonants
char c; // assign some character to 'c'
if ("aeiouAEIOU".indexOf(c) != -1) {
  // handle vowel case
} else if ("!@#$%,.".indexOf(c) != -1) {
  // handle punctuation case
} else if ("0123456789".indexOf(c) != -1) {
  // handle digit case
} else {
  // handle consonant case, assuming other characters are not possible
}

Of course, if this gets any more complicated, I'd recommend a regex matcher.

You can write extention method:

public static async Task<Tout> ReadAsAsync<Tout>(this System.Net.Http.HttpContent content) {
    return Newtonsoft.Json.JsonConvert.DeserializeObject<Tout>(await content.ReadAsStringAsync());
}

@echo off
for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a"
set "YY=%dt:~2,2%" & set "YYYY=%dt:~0,4%" & set "MM=%dt:~4,2%" & set "DD=%dt:~6,2%"
set "HH=%dt:~8,2%" & set "Min=%dt:~10,2%" & set "Sec=%dt:~12,2%"
set "datestamp=%YYYY%.%MM%.%DD%.%HH%.%Min%.%Sec%"
set drive=your backup folder
set databaseName=your databasename
set user="your database user"
set password="your database password"
subst Z: "C:\Program Files\7-Zip" 
subst M: "D:\AppServ\MySQL\bin"
set zipFile="%drive%\%databaseName%-%datestamp%.zip"
set sqlFile="%drive%\%databaseName%-%datestamp%.sql"
M:\mysqldump.exe --user=%user% --password=%password% --result-file="%sqlFile%" --databases %databaseName%
@echo Mysql Backup Created
Z:\7z.exe a -tzip "%zipFile%" "%sqlFile%"
@echo File Compress End
del %sqlFile%
@echo Delete mysql file
pause;

I was searching for this answer for a while. Now I got it in the official gulp documentation.

If you want to perform a gulp task when the last one is complete, you have to return a stream:

gulp.task('wiredep', ['dev-jade'], function () {_x000D_
    var stream = gulp.src(paths.output + '*.html')_x000D_
        .pipe($.wiredep())_x000D_
        .pipe(gulp.dest(paths.output));_x000D_
_x000D_
    return stream; // execute next task when this is completed_x000D_
});_x000D_
_x000D_
// First will execute and complete wiredep task_x000D_
gulp.task('prod-jade', ['wiredep'], function() {_x000D_
    gulp.src(paths.output + '**/*.html')_x000D_
        .pipe($.minifyHtml())_x000D_
        .pipe(gulp.dest(paths.output));_x000D_
});

Since Bootstrap 3 removed the submenu part and we need to adapt ourselves the style, I think it's better to go with SmartMenu Bootstrap: https://vadikom.github.io/smartmenus/src/demo/bootstrap-navbar.html#

That would save us time on mobile responsive and style.

This plugin also very promising.

Here's a detailed explanation about the calculation of MaxClients and MaxRequestsPerChild

http://web.archive.org/web/20160415001028/http://www.genericarticles.com/mediawiki/index.php?title=How_to_optimize_apache_web_server_for_maximum_concurrent_connections_or_increase_max_clients_in_apache

ServerLimit 16
StartServers 2
MaxClients 200
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25

First of all, whenever an apache is started, it will start 2 child processes which is determined by StartServers parameter. Then each process will start 25 threads determined by ThreadsPerChild parameter so this means 2 process can service only 50 concurrent connections/clients i.e. 25x2=50. Now if more concurrent users comes, then another child process will start, that can service another 25 users. But how many child processes can be started is controlled by ServerLimit parameter, this means that in the configuration above, I can have 16 child processes in total, with each child process can handle 25 thread, in total handling 16x25=400 concurrent users. But if number defined in MaxClients is less which is 200 here, then this means that after 8 child processes, no extra process will start since we have defined an upper cap of MaxClients. This also means that if I set MaxClients to 1000, after 16 child processes and 400 connections, no extra process will start and we cannot service more than 400 concurrent clients even if we have increase the MaxClient parameter. In this case, we need to also increase ServerLimit to 1000/25 i.e. MaxClients/ThreadsPerChild=40 So this is the optmized configuration to server 1000 clients

<IfModule mpm_worker_module>
    ServerLimit          40
    StartServers          2
    MaxClients          1000
    MinSpareThreads      25
    MaxSpareThreads      75 
    ThreadsPerChild      25
    MaxRequestsPerChild   0
</IfModule>

This work for me

<%= f.select :status, [["Single", "single"], ["Married", "married"], ["Engaged", "engaged"], ["In a Relationship", "relationship"]], {}, {class: "form-control"} %>

No, == between Integer, Long etc will check for reference equality - i.e.

Integer x = ...;
Integer y = ...;

System.out.println(x == y);

this will check whether x and y refer to the same object rather than equal objects.

So

Integer x = new Integer(10);
Integer y = new Integer(10);

System.out.println(x == y);

is guaranteed to print false. Interning of "small" autoboxed values can lead to tricky results:

Integer x = 10;
Integer y = 10;

System.out.println(x == y);

This will print true, due to the rules of boxing (JLS section 5.1.7). It's still reference equality being used, but the references genuinely are equal.

If the value p being boxed is an integer literal of type int between -128 and 127 inclusive (§3.10.1), or the boolean literal true or false (§3.10.3), or a character literal between '\u0000' and '\u007f' inclusive (§3.10.4), then let a and b be the results of any two boxing conversions of p. It is always the case that a == b.

Personally I'd use:

if (x.intValue() == y.intValue())

or

if (x.equals(y))

As you say, for any comparison between a wrapper type (Integer, Long etc) and a numeric type (int, long etc) the wrapper type value is unboxed and the test is applied to the primitive values involved.

This occurs as part of binary numeric promotion (JLS section 5.6.2). Look at each individual operator's documentation to see whether it's applied. For example, from the docs for == and != (JLS 15.21.1):

If the operands of an equality operator are both of numeric type, or one is of numeric type and the other is convertible (§5.1.8) to numeric type, binary numeric promotion is performed on the operands (§5.6.2).

and for <, <=, > and >= (JLS 15.20.1)

The type of each of the operands of a numerical comparison operator must be a type that is convertible (§5.1.8) to a primitive numeric type, or a compile-time error occurs. Binary numeric promotion is performed on the operands (§5.6.2). If the promoted type of the operands is int or long, then signed integer comparison is performed; if this promoted type is float or double, then floating-point comparison is performed.

Note how none of this is considered as part of the situation where neither type is a numeric type.

NB: this is LINQ to objects, I am not 100% sure if it work in LINQ to entities, and have no time to check it right now. In fact it isn't too difficult to translate it to x in [A, B, C] but you have to check for yourself.

So, instead of Contains as a replacement of the ???? in your code you can use Any which is more LINQ-uish:

// Filter the orders based on the order status
var filteredOrders = from order in orders.Order
                     where new[] { "A", "B", "C" }.Any(s => s == order.StatusCode)
                     select order;

It's the opposite to what you know from SQL this is why it is not so obvious.

Of course, if you prefer fluent syntax here it is:

var filteredOrders = orders.Order.Where(order => new[] {"A", "B", "C"}.Any(s => s == order.StatusCode));

Here we again see one of the LINQ surprises (like Joda-speech which puts select at the end). However it is quite logical in this sense that it checks if at least one of the items (that is any) in a list (set, collection) matches a single value.

git reset --soft HEAD~1 should do what you want. After this, you'll have the first changes in the index (visible with git diff --cached), and your newest changes not staged. git status will then look like this:

# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#       modified:   foo.java
#
# Changes not staged for commit:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#       modified:   foo.java
#

You can then do git add foo.java and commit both changes at once.

You have mentioned Wrong id

alert(document.getElementById("name").value);

if you want to use name attribute then

alert(document.getElementsByName("username")[0].value);

Updates:

input type="text" id="name" name="username"  

id is different from name

You can clean cache in React Native >= 0.50 and npm > 5 :

watchman watch-del-all && 
rm -rf $TMPDIR/react-native-packager-cache-* &&
rm -rf $TMPDIR/metro-bundler-cache-* && 
rm -rf node_modules/ 
&& npm cache clean --force &&
npm install && 
npm start -- --reset-cache

Apart from cleaning npm cache you might need to reset simulator or clean build etc.

You can use above function for casting not similar class objects (PHP >= 5.3)

/**
 * Class casting
 *
 * @param string|object $destination
 * @param object $sourceObject
 * @return object
 */
function cast($destination, $sourceObject)
{
    if (is_string($destination)) {
        $destination = new $destination();
    }
    $sourceReflection = new ReflectionObject($sourceObject);
    $destinationReflection = new ReflectionObject($destination);
    $sourceProperties = $sourceReflection->getProperties();
    foreach ($sourceProperties as $sourceProperty) {
        $sourceProperty->setAccessible(true);
        $name = $sourceProperty->getName();
        $value = $sourceProperty->getValue($sourceObject);
        if ($destinationReflection->hasProperty($name)) {
            $propDest = $destinationReflection->getProperty($name);
            $propDest->setAccessible(true);
            $propDest->setValue($destination,$value);
        } else {
            $destination->$name = $value;
        }
    }
    return $destination;
}

EXAMPLE:

class A 
{
  private $_x;   
}

class B 
{
  public $_x;   
}

$a = new A();
$b = new B();

$x = cast('A',$b);
$x = cast('B',$a);

You forgot to add self as a parameter to the function worker() in the class KeyStatisticCollection.

No this step isn't equal to downloading the laravel.zip by using the command composer create-project laravel/laravel laravel you actually download the laravel project as well as dependent packages so its one step ahead.

If you are using windows environment you can solve the problem by deleting the composer environment variable you created to install the composer. And this command will run properly.

You should put the input for the last name into the same div where you have the first name.

<div>
    <label for="username">First Name</label>
    <input id="user_first_name" name="user[first_name]" size="30" type="text" />
    <input id="user_last_name" name="user[last_name]" size="30" type="text" />
</div>

Then, in your CSS give your #user_first_name and #user_last_name height and float them both to the left. For example:

#user_first_name{
    max-width:100px; /*max-width for responsiveness*/
    float:left;
}

#user_lastname_name{
    max-width:100px;
    float:left;
}

One easy way is to drag and drop. It will copy files to /sdcard/Download. You can copy whole folders or multiple files. Make sure that "Enable Clipboard Sharing" is enabled. (under ...->Settings)

Actually you have 2 problems here: First is that you don't have ssh installed, second is that you don't know how to deploy

Install SSH

It seems that ssh is not installed on your computer.

You can install openssh from here : http://openssh.en.softonic.com/download

Generate your key

Than you will have to geneate your ssh-key. There's a good tutorial about this here:

https://help.github.com/articles/generating-ssh-keys#platform-windows

Deploy

To deploy, you just have to push your code over git. Something like this:

git push fort master

If you get permission denied, be sure that you have put your public_key in the dashboard in the git tab.

SSH

The ssh command gives you access to your remote node. You should have received a password by email and now that you have ssh installed, you should be asked for a password when trying to connect. just input that password. If you want to use your private ssh key to connect to your server rather then typing that password, you can follow this : http://fortrabbit.com/docs/how-to/ssh-sftp/enable-public-key-authentication

Just for completeness, since MySQL and Postgres have already been mentioned: With SQLite, use "pragma table_info()"

sqlite> pragma table_info('table_name');
cid         name        type        notnull     dflt_value  pk        
----------  ----------  ----------  ----------  ----------  ----------
0           id          integer     99                      1         
1           name                    0                       0         

:%s/\r//g 

worked for me today. But my situation may have been slightly different.

You are looking to see if a single value is in an array. Use in_array.

However note that case is important, as are any leading or trailing spaces. Use var_dump to find out the length of the strings too, and see if they fit.

The MAC address of a client (in the sense of the computer that issued the HTTP request) is overwritten by every router between the client and the server.

Client IP is conveniently provided to the script in $_SERVER['REMOTE_ADDR']. In some scenarios, particularly if your web server is behind a proxy (i.e. a caching proxy) $_SERVER['REMOTE ADDR'] will return the IP of the proxy, and there will be an extra value, often $_SERVER['HTTP_X_FORWARDED_FOR'], that contains the IP of the original request client.

Sometimes, particularly when you're dealing with an anonymizing proxy that you don't control, the proxy won't return the real IP address, and all you can hope for is the IP address of the proxy.

Another possibility would be to use pidof it usually comes with most distributions. It will return you the PID of a given process by using it's name.

pidof process_name

This way you could store that information in a variable and execute kill -9 on it.

#!/bin/bash
pid=`pidof process_name`
kill -9 $pid

unsafe.park is pretty much the same as thread.wait, except that it's using architecture specific code (thus the reason it's 'unsafe'). unsafe is not made available publicly, but is used within java internal libraries where architecture specific code would offer significant optimization benefits. It's used a lot for thread pooling.

So, to answer your question, all the thread is doing is waiting for something, it's not really using any CPU. Considering that your original stack trace shows that you're using a lock I would assume a deadlock is going on in your case.

Yes I know you have almost certainly already solved this issue by now. However, you're one of the top results if someone googles sun.misc.unsafe.park. I figure answering the question may help others trying to understand what this method that seems to be using all their CPU is.

Posting data is a matter of sending a query string (just like the way you would send it with an URL after the ?) as the request body.

This requires Content-Type and Content-Length headers, so the receiving server knows how to interpret the incoming data. ^(*)

var querystring = require('querystring');
var http = require('http');

var data = querystring.stringify({
      username: yourUsernameValue,
      password: yourPasswordValue
    });

var options = {
    host: 'my.url',
    port: 80,
    path: '/login',
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Length': Buffer.byteLength(data)
    }
};

var req = http.request(options, function(res) {
    res.setEncoding('utf8');
    res.on('data', function (chunk) {
        console.log("body: " + chunk);
    });
});

req.write(data);
req.end();

^(*) Sending data requires the Content-Type header to be set correctly, i.e. application/x-www-form-urlencoded for the traditional format that a standard HTML form would use.

It's easy to send JSON (application/json) in exactly the same manner; just JSON.stringify() the data beforehand.

URL-encoded data supports one level of structure (i.e. key and value). JSON is useful when it comes to exchanging data that has a nested structure.

The bottom line is: The server must be able to interpret the content type in question. It could be text/plain or anything else; there is no need to convert data if the receiving server understands it as it is.

Add a charset parameter (e.g. application/json; charset=Windows-1252) if your data is in an unusual character set, i.e. not UTF-8. This can be necessary if you read it from a file, for example.

first, create a new branch in the current position (in case you need your old 'screwed up' history):

git branch fubar-pin

update your list of remote branches and sync new commits:

git fetch --all

then, reset your branch to the point where origin/branch points to:

git reset --hard origin/branch

be careful, this will remove any changes from your working tree!

A simple but dirty trick is to simply add the offset you want to the image you are using as background. it's not maintainable, but it gets the job done.

If the format is guaranteed to be correct YYYY/MM/DD and exactly the same between the two fields then you can use:

if (startdate > enddate) {
   alert('error'
}

As a string comparison

If you're still wondering how to solve it.

I use

$protected $dates = ['created_at','updated_at','aired'];

In my model and in my where i do

where('aired','>=',time())

So just use the unix to compaire in where.

In views on the otherhand you have to use the date object.

Hope it helps someone!

As you mentioned, prompt works for browsers all the way back to IE:

var answer = prompt('question', 'defaultAnswer');

For Node.js > v7.6, you can use console-read-write, which is a wrapper around the low-level readline module:

const io = require('console-read-write');

async function main() {
  // Simple readline scenario
  io.write('I will echo whatever you write!');
  io.write(await io.read());

  // Simple question scenario
  io.write(`hello ${await io.ask('Who are you?')}!`);

  // Since you are not blocking the IO, you can go wild with while loops!
  let saidHi = false;
  while (!saidHi) {
    io.write('Say hi or I will repeat...');
    saidHi = await io.read() === 'hi';
  }

  io.write('Thanks! Now you may leave.');
}

main();
// I will echo whatever you write!
// > ok
// ok
// Who are you? someone
// hello someone!
// Say hi or I will repeat...
// > no
// Say hi or I will repeat...
// > ok
// Say hi or I will repeat...
// > hi
// Thanks! Now you may leave.

For SpiderMonkey, simple readline as suggested by @MooGoo and @Zaz.

As everything is inside a string, external string variables being substituted in will need to be escaped and quoted twice. Using dollar quoting instead will not give full protection against SQL injection.

I was having this issue after installing both Windows Python and Cygwin Python, and trying to run Cygwin Python from Cygwin. I solved it by exporting PYTHONHOME=/usr/ and PYTHONPATH=/usr/lib/python2.7

In this case, as you want to change the src of the first value of your element, you have no need to build up a function. You can change this right in the element:

<a href='#' onclick='this.firstChild.src="../template/save.png"')'>
  <img src="../template/edit.png" id="edit-save"/>
</a>

You have several ways to do this. You can also create a function to automatize the process:

function changeSrc(p, t) { /* where p: Parent, t: ToSource */
  p.firstChild.src = t
}

Then you can:

<a href='#' onclick='changeSrc(this, "../template/save.png");'>
  <img src="../template/edit.png" id="edit-save"/>
</a>

The format defined in RFC2617 is credentials = auth-scheme #auth-param. So, in agreeing with fumanchu, I think the corrected authorization scheme would look like

Authorization: FIRE-TOKEN apikey="0PN5J17HBGZHT7JJ3X82", hash="frJIUN8DYpKDtOLCwo//yllqDzg="

Where FIRE-TOKEN is the scheme and the two key-value pairs are the auth parameters. Though I believe the quotes are optional (from Apendix B of p7-auth-19)...

auth-param = token BWS "=" BWS ( token / quoted-string )

I believe this fits the latest standards, is already in use (see below), and provides a key-value format for simple extension (if you need additional parameters).

Some examples of this auth-param syntax can be seen here...

yes block are the most used functionality , so in order to avoid the retain cycle we should avoid using the strong variable,including self inside the block, inspite use the _weak or weakself.

Include the fonts Copy over all the font files to a /fonts directory near your CSS.

1. Include the CSS or LESS You have two options for enabling the fonts in your project: vanilla CSS or source LESS. For vanilla CSS, just include the compiled CSS file from the /css in the repository.
2. For LESS, copy over the .less files from /less into your existing Bootstrap directory. Then import it into bootstrap.less via @import "bootstrap-glyphicons.less";. Recompile when ready.
3. Add some icons! After you've added the fonts and CSS, you can get to using the icons. For example, <span class="glyphicon glyphicon-ok"></span>

You need to download log4j and add in your classpath.

In Java 8:

Map<String, Long> counts =
    list.stream().collect(Collectors.groupingBy(e -> e, Collectors.counting()));

This is a bit late but I know it will help someone:

If you are using datetimepicker make sure you include the right CSS and JS files. datetimepicker uses(Take note of their names);

https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datetimepicker/4.17.37/css/bootstrap-datetimepicker.css

and

https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datetimepicker/4.17.37/js/bootstrap-datetimepicker.min.js

On the above question asked by @mindfreak,The main problem is due to the imported files.

It will overflow and wrap around to Long.MIN_VALUE.

Its not too likely though. Even if you increment 1,000,000 times per second it will take about 300,000 years to overflow.

You need to disable the button in the onsubmit event of the <form>:

<form action='/' method='POST' onsubmit='disableButton()'>
    <input name='txt' type='text' required />
    <button id='btn' type='submit'>Post</button>
</form>

<script>
    function disableButton() {
        var btn = document.getElementById('btn');
        btn.disabled = true;
        btn.innerText = 'Posting...'
    }
</script>

Note: this way if you have a form element which has the required attribute will work.

If you have control to the {this.props.match.description} and if you are using JSX. I would recommend not to use "dangerouslySetInnerHTML".

// In JSX, you can define a html object rather than a string to contain raw HTML
let description = <h1>Hi there!</h1>;

// Here is how you print
return (
    {description}
);

You can create a button in window1 and double click on it. It will create a new click handler, where inside you can write something like this:

var window2 = new Window2();
window2.Show();

I tried Ninh Pham's solution but it didn't work for me until I tweaked it - see below. Remove contentType and don't encode your json data

$.fn.postJSON = function(url, data) {
    return $.ajax({
            type: 'POST',
            url: url,
            data: data,
            dataType: 'json'
        });

You can use urlib2 and parse the HTML yourself.

Or try Beautiful Soup to do some of the parsing for you.

It doesn't work with PostgreSQL 9.4 on my Linux machine if i change a table through table editor in pgAdmin and works if i change table through ordinary query. Manual changes in pg_trigger table also don't work without server restart but dynamic query like on postgresql.nabble.com ENABLE / DISABLE ALL TRIGGERS IN DATABASE works. It could be useful when you need some tuning.

For example if you have tables in a particular namespace it could be:

create or replace function disable_triggers(a boolean, nsp character varying) returns void as
$$
declare 
act character varying;
r record;
begin
    if(a is true) then
        act = 'disable';
    else
        act = 'enable';
    end if;

    for r in select c.relname from pg_namespace n
        join pg_class c on c.relnamespace = n.oid and c.relhastriggers = true
        where n.nspname = nsp
    loop
        execute format('alter table %I %s trigger all', r.relname, act); 
    end loop;
end;
$$
language plpgsql;

If you want to disable all triggers with certain trigger function it could be:

create or replace function disable_trigger_func(a boolean, f character varying) returns void as
$$
declare 
act character varying;
r record;
begin
    if(a is true) then
        act = 'disable';
    else
        act = 'enable';
    end if;

    for r in select c.relname from pg_proc p 
        join pg_trigger t on t.tgfoid = p.oid
        join pg_class c on c.oid = t.tgrelid
        where p.proname = f
    loop
        execute format('alter table %I %s trigger all', r.relname, act); 
    end loop;
end;
$$
language plpgsql;

There are another control options of trigger firing process:

ALTER TABLE ... ENABLE REPLICA TRIGGER ... - trigger will fire in replica mode only.

ALTER TABLE ... ENABLE ALWAYS TRIGGER ... - trigger will fire always (obviously)

I realize that you want to avoid reading the whole JSON file into memory if possible, however if you have the memory available it may not be a bad idea performance-wise. Using node.js's require() on a json file loads the data into memory really fast.

I ran two tests to see what the performance looked like on printing out an attribute from each feature from a 81MB geojson file.

In the 1st test, I read the entire geojson file into memory using var data = require('./geo.json'). That took 3330 milliseconds and then printing out an attribute from each feature took 804 milliseconds for a grand total of 4134 milliseconds. However, it appeared that node.js was using 411MB of memory.

In the second test, I used @arcseldon's answer with JSONStream + event-stream. I modified the JSONPath query to select only what I needed. This time the memory never went higher than 82MB, however, the whole thing now took 70 seconds to complete!

Use below code:

// Variable to check
$email = "[email protected]";

// Remove all illegal characters from email
$email = filter_var($email, FILTER_SANITIZE_EMAIL);

// Validate e-mail
if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
  echo("Email is a valid email address");
} else {
  echo("Oppps! Email is not a valid email address");
}

Expanding on @Avenir Çokaj's answer

Being a novice even I did not understand the error message clearly at first.

What the error message indicates is that in your formGroup you have an element that doesn't get accounted for in your formControl. (Intentionally/Accidentally)

If you intend on not validating this field but still want to use the ngModel on this input element please add the flag to indicate it's a standalone component without a need for validation as mentioned by @Avenir above.

Here's a solution that should always work and doesn't remove the hash.

let currentPage = new URL(window.location.href);
currentPage.searchParams.set('r', (+new Date * Math.random()).toString(36).substring(0, 5));
window.location.href = currentPage.href;

Guessing from the information I have, you're not actually compiling the program, but trying to run it. That is, ALL_BUILD is set as your startup project. (It should be in a bold font, unlike the other projects in your solution) If you then try to run/debug, you will get the error you describe, because there is simply nothing to run.

The project is most likely generated via CMAKE and included in your Visual Studio solution. Set any of the projects that do generate a .exe as the startup project (by right-clicking on the project and selecting "set as startup project") and you will most likely will be able to start those from within Visual Studio.

To merge one branch into another, such as merging "feature_x" branch into "master" branch:

git checkout master

git merge feature_x

This page is the first result for several search engines when looking for "git merge one branch into another". However, the original question is more specific and special case than the title would suggest.
It is also more complex than both the subject and the search expression. As such, this is a minimal but explanatory answer for the benefit of most visitors.

#include <iostream>
#include <string>
#include <vector>
#include <boost/assign/list_of.hpp>

int main()
{
    const std::vector< std::string > v = boost::assign::list_of( "abc" )( "xyz" );
    std::copy(
        v.begin(),
        v.end(),
        std::ostream_iterator< std::string >( std::cout, "\n" ) );
}

My suggestion would be to use Unit Tests.

In your application do the following switches in Program.cs:

#if DEBUG
    public class Program
#else
    class Program
#endif

and the same for static Main(string[] args).

Or alternatively use Friend Assemblies by adding

[assembly: InternalsVisibleTo("TestAssembly")]

to your AssemblyInfo.cs.

Then create a unit test project and a test that looks a bit like so:

[TestClass]
public class TestApplication
{
    [TestMethod]
    public void TestMyArgument()
    {
        using (var sw = new StringWriter())
        {
            Console.SetOut(sw); // this makes any Console.Writes etc go to sw

            Program.Main(new[] { "argument" });

            var result = sw.ToString();

            Assert.AreEqual("expected", result);
        }
    }
}

This way you can, in an automated way, test multiple inputs of arguments without having to edit your code or change a menu setting every time you want to check something different.

It worked for me using:

curl -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{"id":100}' http://localhost/api/postJsonReader.do

It was happily mapped to the Spring controller:

@RequestMapping(value = "/postJsonReader", method = RequestMethod.POST)
public @ResponseBody String processPostJsonData(@RequestBody IdOnly idOnly) throws Exception {
        logger.debug("JsonReaderController hit! Reading JSON data!"+idOnly.getId());
        return "JSON Received";
}

IdOnly is a simple POJO with an id property.

Try the following-sibling axis (following-sibling::td).

Based on this article, using subtree is what worked for me and only applicable history was transferred. Posting here in case anyone needs the steps (make sure to replace the placeholders with values applicable to you):

in your source repository split subfolder into a new branch

git subtree split --prefix=<source-path-to-merge> -b subtree-split-result

in your destination repo merge in the split result branch

git remote add merge-source-repo <path-to-your-source-repository>
git fetch merge-source-repo
git merge -s ours --no-commit merge-source-repo/subtree-split-result
git read-tree --prefix=<destination-path-to-merge-into> -u merge-source-repo/subtree-split-result

verify your changes and commit

git status
git commit

Don't forget to

Clean up by deleting the subtree-split-result branch

git branch -D subtree-split-result

Remove the remote you added to fetch the data from source repo

git remote rm merge-source-repo

This is what works for me:

if (typeof myVar === 'string' || myVar instanceof String)
// it's a string
else
// it's something else

This happens because "Person" is a class, so it is passed by reference. In the statement "b = a" you are just copying a reference to the one and only "Person" instance that you created with the keyword new.

The easiest way to have the behavior that you are looking for is to use a "value type".

Just change the Person declaration from

class Person

to

struct Person

Specifically relating to the error you're getting, you can't do something like this in PHP for a nullable field in MySQL:

$sql = 'INSERT INTO table (col1, col2) VALUES(' . $col1 . ', ' . null . ')';

Because null in PHP will equate to an empty string which is not the same as a NULL value in MysQL. Instead you want to do this:

$sql = 'INSERT INTO table (col1, col2) VALUES(' . $col1 . ', ' . (is_null($col2) ? 'NULL' : $col2). ')';

Of course you don't have to use is_null but I figure that it demonstrates the point a little better. Probably safer to use empty() or something like that. And if $col2 happens to be a string which you would enclose in double quotes in the query, don't forget not to include those around the 'NULL' string, otherwise it wont work.

Hope that helps!

You should use the * operator, like foo(*values) Read the Python doc unpackaging argument lists.

Also, do read this: http://www.saltycrane.com/blog/2008/01/how-to-use-args-and-kwargs-in-python/

def foo(x,y,z):
   return "%d, %d, %d" % (x,y,z)

values = [1,2,3]

# the solution.
foo(*values)

Just use dynamic as the argument:

var list = new List<dynamic>();

Without Installing python-docx

docx is basically is a zip file with several folders and files within it. In the link below you can find a simple function to extract the text from docx file, without the need to rely on python-docx and lxml the latter being sometimes hard to install:

http://etienned.github.io/posts/extract-text-from-word-docx-simply/

The simple answer is you should write code for rvalue references like you would regular references code, and you should treat them the same mentally 99% of the time. This includes all the old rules about returning references (i.e. never return a reference to a local variable).

Unless you are writing a template container class that needs to take advantage of std::forward and be able to write a generic function that takes either lvalue or rvalue references, this is more or less true.

One of the big advantages to the move constructor and move assignment is that if you define them, the compiler can use them in cases were the RVO (return value optimization) and NRVO (named return value optimization) fail to be invoked. This is pretty huge for returning expensive objects like containers & strings by value efficiently from methods.

Now where things get interesting with rvalue references, is that you can also use them as arguments to normal functions. This allows you to write containers that have overloads for both const reference (const foo& other) and rvalue reference (foo&& other). Even if the argument is too unwieldy to pass with a mere constructor call it can still be done:

std::vector vec;
for(int x=0; x<10; ++x)
{
    // automatically uses rvalue reference constructor if available
    // because MyCheapType is an unamed temporary variable
    vec.push_back(MyCheapType(0.f));
}


std::vector vec;
for(int x=0; x<10; ++x)
{
    MyExpensiveType temp(1.0, 3.0);
    temp.initSomeOtherFields(malloc(5000));

    // old way, passed via const reference, expensive copy
    vec.push_back(temp);

    // new way, passed via rvalue reference, cheap move
    // just don't use temp again,  not difficult in a loop like this though . . .
    vec.push_back(std::move(temp));
}

The STL containers have been updated to have move overloads for nearly anything (hash key and values, vector insertion, etc), and is where you will see them the most.

You can also use them to normal functions, and if you only provide an rvalue reference argument you can force the caller to create the object and let the function do the move. This is more of an example than a really good use, but in my rendering library, I have assigned a string to all the loaded resources, so that it is easier to see what each object represents in the debugger. The interface is something like this:

TextureHandle CreateTexture(int width, int height, ETextureFormat fmt, string&& friendlyName)
{
    std::unique_ptr<TextureObject> tex = D3DCreateTexture(width, height, fmt);
    tex->friendlyName = std::move(friendlyName);
    return tex;
}

It is a form of a 'leaky abstraction' but allows me to take advantage of the fact I had to create the string already most of the time, and avoid making yet another copying of it. This isn't exactly high-performance code but is a good example of the possibilities as people get the hang of this feature. This code actually requires that the variable either be a temporary to the call, or std::move invoked:

// move from temporary
TextureHandle htex = CreateTexture(128, 128, A8R8G8B8, string("Checkerboard"));

or

// explicit move (not going to use the variable 'str' after the create call)
string str("Checkerboard");
TextureHandle htex = CreateTexture(128, 128, A8R8G8B8, std::move(str));

or

// explicitly make a copy and pass the temporary of the copy down
// since we need to use str again for some reason
string str("Checkerboard");
TextureHandle htex = CreateTexture(128, 128, A8R8G8B8, string(str));

but this won't compile!

string str("Checkerboard");
TextureHandle htex = CreateTexture(128, 128, A8R8G8B8, str);

As explained in this thread on the cxf-user mailing list, rather than having the CXFServlet load its own spring context from user-webservice-servlet.xml, you can just load the whole lot into the root context. Rename your existing user-webservice-servlet.xml to some other name (e.g. user-webservice-beans.xml) then change your contextConfigLocation parameter to something like:

<servlet>
  <servlet-name>myservlet</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>myservlet</servlet-name>
  <url-pattern>*.htm</url-pattern>
</servlet-mapping>

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
    /WEB-INF/applicationContext.xml
    /WEB-INF/user-webservice-beans.xml
  </param-value>
</context-param>

<servlet>
  <servlet-name>user-webservice</servlet-name>
  <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
  <load-on-startup>2</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>user-webservice</servlet-name>
  <url-pattern>/UserService/*</url-pattern>
</servlet-mapping>

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

I am in the same boat as you do. I need to study for tech interviews, but memorizing a list is not really helpful. If you have 3-4 hours to spare, and want to do a deeper dive, I recommend checking out

mycodeschool
I’ve looked on Coursera and other resources such as blogs and textbooks, but I find them either not comprehensive enough or at the other end of the spectrum, too dense with prerequisite computer science terminologies.

The dude in the video have a bunch of lectures on data structures. Don’t mind the silly drawings, or the slight accent at all. You need to understand not just which data structure to select, but some other points to consider when people think about data structures:

• pros and cons of the common data structures
• why each data structure exist
• how it actually work in the memory
• specific questions/exercises and deciding which structure to use for maximum efficiency
• lucid Big 0 explanation

I also posted notes on github if you are interested.

i did make project and it works but before that try to check the package name in your manifest, rebuild and clean your project. if the problem didn't resolve, than make your project

It looks like you are not providing a value for the primary key field DB_ID. If that is a primary key, you must provide a unique value for that column. The only way not to provide it would be to create a database trigger that, on insert, would provide a value, most likely derived from a sequence.

If this is a restoration from another database and there is a sequence on this new instance, it might be trying to reuse a value. If the old data had unique keys from 1 - 1000 and your current sequence is at 500, it would be generating values that already exist. If a sequence does exist for this table and it is trying to use it, you would need to reconcile the values in your table with the current value of the sequence.

You can use SEQUENCE_NAME.CURRVAL to see the current value of the sequence (if it exists of course)

In case you need to nest more than one null coalescing operation such as:

model?.data()?.first()

This is not a problem easily solved with or. It also cannot be solved with .get() which requires a dictionary type or similar (and cannot be nested anyway) or getattr() which will throw an exception when NoneType doesn't have the attribute.

The relevant pip considering adding null coalescing to the language is PEP 505 and the discussion relevant to the document is in the python-ideas thread.

Google, no API needed:

$data = file_get_contents('http://picasaweb.google.com/data/entry/api/user/<USER_ID>?alt=json');
$d = json_decode($data);
$avatar = $d->{'entry'}->{'gphoto$thumbnail'}->{'$t'};

CHANGE: the 64 in "s64" for the size

You can update values from another table using inner join like this

UPDATE [table1_name] AS t1 INNER JOIN [table2_name] AS t2 ON t1.column1_name] = t2.[column1_name] SET t1.[column2_name] = t2.column2_name];

Follow here to know how to use this query http://www.voidtricks.com/mysql-inner-join-update/

or you can use select as subquery to do this

UPDATE [table_name] SET [column_name] = (SELECT [column_name] FROM [table_name] WHERE [column_name] = [value]) WHERE [column_name] = [value];

query explained in details here http://www.voidtricks.com/mysql-update-from-select/

You can use a custom directive (with support to textarea, select, radio and checkbox), check out this blog post https://glaucocustodio.github.io/2014/10/20/init-ng-model-from-form-fields-attributes/.

I tried all of the suggestions above and none of them worked for me, they changed the clientWidth and clientHeight not the actual width and height.

The jQuery docs for $().width and height methods says: "Note that .width("value") sets the content width of the box regardless of the value of the CSS box-sizing property."

The css approach did the same thing so I had to use the $().attr() methods instead.

_canvas.attr('width', 100);
_canvas.attr('height', 200);

I don't know is this affect me because I was trying to resize a element and it is some how different or not.

max-device-width is the device rendering width

@media all and (max-device-width: 400px) {
    /* styles for devices with a maximum width of 400px and less
       Changes only on device orientation */
}

@media all and (max-width: 400px) {
    /* styles for target area with a maximum width of 400px and less
       Changes on device orientation , browser resize */
}

The max-width is the width of the target display area means the current size of browser.

just to go File -> Sync Project with Gradle files then it solves problem.

I think you achieve with change and keyUp event.
