Run these three commands to make sure that you have all the relevant packages installed:

pip install bs4
pip install html5lib
pip install lxml

Then restart your Python IDE, if needed.

That should take care of anything related to this issue.

Set up a virtualenv:

% curl -kLso /tmp/get-pip.py https://bootstrap.pypa.io/get-pip.py 
% sudo python /tmp/get-pip.py

These commands install pip into the global site-packages directory.

% sudo pip install virtualenv

and ditto for virtualenv:

% mkdir -p ~/.virtualenvs

I like my virtualenvs under one tree in my home directory called .virtualenvs

% virtualenv ~/.virtualenvs/lxmltest

Creates a virtualenv.

% . ~/.virtualenvs/lxmltest/bin/activate

Removes the need to specify the full path to pip/python in this virtualenv.

% pip install lxml

Alternatively execute ~/.virtualenvs/lxmltest/bin/pip install lxml if you chose not to follow the previous step. Note, I'm not sure how far along you are, so some of these steps can be safely skipped. Of course, if you mess something up, you can always rm -Rf ~/.virtualenvs/lxmltest and start again from a new virtualenv.

You should define source code encoding, add this to the top of your script:

# -*- coding: utf-8 -*-

The reason why it works differently in console and in the IDE is, likely, because of different default encodings set. You can check it by running:

import sys
print sys.getdefaultencoding()

Also see:

• Why declare unicode by string in python?
• Changing default encoding of Python?

From Ubuntu 18.4 (Bionic Beaver) it is advisable to use apt instead of apt-get since it has much better structural form.

sudo apt install libxml2-dev libxslt1-dev python-dev

If you're happy with a possibly older version of lxml altogether though, you could try

sudo apt install python-lxml

For completeness - adding to accepted answer above - in case you are interested in any sibling regardless of the element type you can use variation:

following-sibling::*

Before actually answering your question:

Parameters in a URL (e.g. key=listOfUsers/user1) are GET parameters and you shouldn't be using them for POST requests. A quick explanation of the difference between GET and POST can be found here.

In your case, to make use of REST principles, you should probably have:

http://ip:5000/users
http://ip:5000/users/<user_id>

Then, on each URL, you can define the behaviour of different HTTP methods (GET, POST, PUT, DELETE). For example, on /users/<user_id>, you want the following:

GET /users/<user_id> - return the information for <user_id>
POST /users/<user_id> - modify/update the information for <user_id> by providing the data
PUT - I will omit this for now as it is similar enough to `POST` at this level of depth
DELETE /users/<user_id> - delete user with ID <user_id> 

So, in your example, you want do a POST to /users/user_1 with the POST data being "John". Then the XPath expression or whatever other way you want to access your data should be hidden from the user and not tightly couple to the URL. This way, if you decide to change the way you store and access data, instead of all your URL's changing, you will simply have to change the code on the server-side.

Now, the answer to your question: Below is a basic semi-pseudocode of how you can achieve what I mentioned above:

from flask import Flask
from flask import request

app = Flask(__name__)

@app.route('/users/<user_id>', methods = ['GET', 'POST', 'DELETE'])
def user(user_id):
    if request.method == 'GET':
        """return the information for <user_id>"""
        .
        .
        .
    if request.method == 'POST':
        """modify/update the information for <user_id>"""
        # you can use <user_id>, which is a str but could
        # changed to be int or whatever you want, along
        # with your lxml knowledge to make the required
        # changes
        data = request.form # a multidict containing POST data
        .
        .
        .
    if request.method == 'DELETE':
        """delete user with ID <user_id>"""
        .
        .
        .
    else:
        # POST Error 405 Method Not Allowed
        .
        .
        .

There are a lot of other things to consider like the POST request content-type but I think what I've said so far should be a reasonable starting point. I know I haven't directly answered the exact question you were asking but I hope this helps you. I will make some edits/additions later as well.

Thanks and I hope this is helpful. Please do let me know if I have gotten something wrong.

If you're running python3, you'll have to do:

pip3 install lxml

If you have installed the libxml2 and libxslt, maybe you need to create a symbolic link between libxml2 and libxslt path to python2.6 include path. Also you can try to add INCLUDE environment argument. Because the gcc command only search this path: -I/usr/include/python2.6.

The outfile should be in binary mode.

outFile = open('output.xml', 'wb')

When plotting a plot using matplotlib:

How to remove the box of the legend?

plt.legend(frameon=False)

How to change the color of the border of the legend box?

leg = plt.legend()
leg.get_frame().set_edgecolor('b')

How to remove only the border of the box of the legend?

leg = plt.legend()
leg.get_frame().set_linewidth(0.0)

Do everything in the inline of UL tag

<ul class="dropdown-menu scrollable-menu" role="menu" style="height: auto;max-height: 200px; overflow-x: hidden;">
                <li><a href="#">Action</a></li>
                <li><a href="#">Another action</a></li>
                <li><a href="#">Something else here</a></li>
                <li><a href="#">Action</a></li>
                ..
                <li><a href="#">Action</a></li>
                <li><a href="#">Another action</a></li>
            </ul>

You can use the ToString overload. Have a look at this page for more info

So just Use myDate.ToString("yyyy-MM-dd HH:mm:ss")

or something equivalent

Maybe could be useful to open an editor from a script shared in a git repository, without assuming which editor could have anyone will use that script, but only that they have git.

Here you can test if editor is set in git config, and also open files not associated with that editor:

alias editor="$(git config core.editor)"
if [ "$(alias editor | sed -r "s/.*='(.*)'/\1/")" != "" ]; then
    editor <filename>
else
    start <filename>
fi

Works great with my .gitconfig on windows:

[core]
    editor = 'C:/Program Files/Notepad++/notepad++.exe' -multiInst -notabbar -nosession -noPlugin

I found a tool called ttyplot in homebrew. It's good. https://github.com/tenox7/ttyplot

If you want to add it directly in the toolbar.

I am going to share my way and it worked for me after implementing following:

Open Php.ini file and fill the all the values in the respective fields by taking ref from Gmail SMTP Settings

Remove comments from the [mail function] Statements which are instructions to the smtp Server and Match their values.

Also the sendmail SMTP server is a Fake server. Its nothing beside a text terminal (Try writing anything on it. :P). It will use gmail s,tp to send Mails. So configure it correctly by matching Gmail SMTP settings:

smtp.gmail.com
Port: 587

 Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:"+198+","+1+","+1)); 
             startActivity(callIntent);

for multiple ordered call

This is used to DTMF calling systems. If call is drop then, you should pass more " , " between numbers.

The other scenario you mush verify is that the file you're trying to unpack is not empty and is valid.

In my case I wasn't downloading the file correctly, after double check and I made sure I had the right file I could unpack it without any issues.

rewrite the whole function as below:

bool IsValidNumber(char * string)
{
   for(int i = 0; i < strlen( string ); i ++)
   {
      //ASCII value of 0 = 48, 9 = 57. So if value is outside of numeric range then fail
      //Checking for negative sign "-" could be added: ASCII value 45.
      if (string[i] < 48 || string[i] > 57)
         return FALSE;
   }

   return TRUE;
}

You do not need to use moment-timezone for this. The main moment.js library has full functionality for working with UTC and the local time zone.

var testDateUtc = moment.utc("2015-01-30 10:00:00");
var localDate = moment(testDateUtc).local();

From there you can use any of the functions you might expect:

var s = localDate.format("YYYY-MM-DD HH:mm:ss");
var d = localDate.toDate();
// etc...

Note that by passing testDateUtc, which is a moment object, back into the moment() constructor, it creates a clone. Otherwise, when you called .local(), it would also change the testDateUtc value, instead of just the localDate value. Moments are mutable.

Also note that if your original input contains a time zone offset such as +00:00 or Z, then you can just parse it directly with moment. You don't need to use .utc or .local. For example:

var localDate = moment("2015-01-30T10:00:00Z");

Test the existence of variavle MyVariable. Returns boolean true or false.

Test-Path variable:\MyVariable

You can write your own JSON parser and make it more generic based on your requirement. Here is one which served my purpose nicely, hope will help you too.

Use the updated version of Firebase and avoid extras. This is enough (but if you need to use storage space or .. you should add them too)

//FIREBASE
implementation 'com.google.firebase:firebase-core:17.2.0'
 implementation 'com.crashlytics.sdk.android:crashlytics:2.10.1'
//ADMob
implementation 'com.google.android.gms:play-services-ads:18.2.0'
//PUSH NOTIFICATION
implementation 'com.google.firebase:firebase-messaging:20.0.0'
implementation 'com.google.firebase:firebase-core:17.2.0'

and update the google-services :

 classpath 'com.google.gms:google-services:4.3.2'

GNU tar has a useful option which gives a functionality of a simple progress bar.

(...) Another available checkpoint action is ‘dot’ (or ‘.’). It instructs tar to print a single dot on the standard listing stream, e.g.:

$ tar -c --checkpoint=1000 --checkpoint-action=dot /var
...

The same effect may be obtained by:

$ tar -c --checkpoint=.1000 /var

Try the format syntax:

print ("{0}. {1} appears {2} times.".format(1, 'b', 3.1415))

Outputs:

1. b appears 3.1415 times.

The print function is called just like any other function, with parenthesis around all its arguments.

python -m pip install -U pip --user //In Windows 

Note: You should provide --user option

pip install -U pip --user //Linux, and MacOS

Or, Run the cmd in Administrator mode.

I have another solution to do it without dynamic query. We can do it with the help of xquery as well.

    SET @Xml = cast(('<A>'+replace('3,4,22,6014',',' ,'</A><A>')+'</A>') AS XML)
    Select @Xml

    SELECT A.value('.', 'varchar(max)') as [Column] FROM @Xml.nodes('A') AS FN(A)

Consider an example having 10 apples. When it implements Iterable, it is like putting each apple in boxes from 1 to 10 and return an iterator which can be used to navigate.

By implementing iterator, we can get any apple, apple in next boxes etc.

So implementing iterable gives an iterator to navigate its elements although to navigate, iterator needs to be implemented.

The way to do this is via the bracket notation.

var test = {_x000D_
    "id": "109",_x000D_
    "No. of interfaces": "4"_x000D_
}_x000D_
alert(test["No. of interfaces"]);

Unfortunately, WebKit browsers do not support styling of <option> tags yet, except for color and background-color.

The most widely used cross browser solution is to use <ul> / <li> and style them using CSS. Frameworks like Bootstrap do this well.

If you want to load the file, as part of your app functionality, then the best approach would be to include and reference to that file.

Another approach is to ask for the file, and load it during runtime. This can be done with the FileAPI. There is also another StackOverflow answer about using it: How to open a local disk file with Javascript?

I will include a slightly modified version for using it in React:

class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      data: null
    };
    this.handleFileSelect = this.handleFileSelect.bind(this);
  }

  displayData(content) {
    this.setState({data: content});
  }

  handleFileSelect(evt) {
    let files = evt.target.files;
    if (!files.length) {
      alert('No file select');
      return;
    }
    let file = files[0];
    let that = this;
    let reader = new FileReader();
    reader.onload = function(e) {
      that.displayData(e.target.result);
    };
    reader.readAsText(file);
  }

  render() {
    const data = this.state.data;
    return (
      <div>
        <input type="file" onChange={this.handleFileSelect}/>
        { data && <p> {data} </p> }
      </div>
    );
  }
}

Use display:none to not show the items, then with JQuery you can use fadeIn() and fadeOut() to hide/unhide the elements.

When working with bootsrap usually face three main problems:

1. How to place the content of the column to the bottom?
2. How to create a multi-row gallery of columns of equal height in one .row?
3. How to center columns horizontally if their total width is less than 12 and the remaining width is odd?

To solve first two problems download this small plugin https://github.com/codekipple/conformity

The third problem is solved here http://www.minimit.com/articles/solutions-tutorials/bootstrap-3-responsive-centered-columns

Common code

<style>
    [class*=col-] {position: relative}
    .row-conformity .to-bottom {position:absolute; bottom:0; left:0; right:0}
    .row-centered {text-align:center}   
    .row-centered [class*=col-] {display:inline-block; float:none; text-align:left; margin-right:-4px; vertical-align:top} 
</style>

<script src="assets/conformity/conformity.js"></script>
<script>
    $(document).ready(function () {
        $('.row-conformity > [class*=col-]').conformity();
        $(window).on('resize', function() {
            $('.row-conformity > [class*=col-]').conformity();
        });
    });
</script>

1. Aligning content of the column to the bottom

<div class="row row-conformity">
    <div class="col-sm-3">
        I<br>create<br>highest<br>column
    </div>
    <div class="col-sm-3">
        <div class="to-bottom">
            I am on the bottom
        </div>
    </div>
</div>

2. Gallery of columns of equal height

<div class="row row-conformity">
    <div class="col-sm-4">We all have equal height</div>
    <div class="col-sm-4">...</div>
    <div class="col-sm-4">...</div>
    <div class="col-sm-4">...</div>
    <div class="col-sm-4">...</div>
    <div class="col-sm-4">...</div>
</div>

3. Horizontal alignment of columns to the center (less than 12 col units)

<div class="row row-centered">
    <div class="col-sm-3">...</div>
    <div class="col-sm-4">...</div>
</div>

All classes can work together

<div class="row row-conformity row-centered">
    ...
</div>

Thanks for the above answers which help me code the above for an MVC project.

Just to add on top of the other answers. In order to initialize a complex static member, you can do it as follows:

Declare your static member as usual.

// myClass.h
class myClass
{
static complexClass s_complex;
//...
};

Make a small function to initialize your class if it's not trivial to do so. This will be called just the one time the static member is initialized. (Note that the copy constructor of complexClass will be used, so it should be well defined).

//class.cpp    
#include myClass.h
complexClass initFunction()
{
    complexClass c;
    c.add(...);
    c.compute(...);
    c.sort(...);
    // Etc.
    return c;
}

complexClass myClass::s_complex = initFunction();

Following the documentation of fopen:

``a'' Open for writing. The file is created if it does not exist. The stream is positioned at the end of the file. Subsequent writes to the file will always end up at the then cur- rent end of file, irrespective of any intervening fseek(3) or similar.

So if you pFile2=fopen("myfile2.txt", "a"); the stream is positioned at the end to append automatically. just do:

FILE *pFile;
FILE *pFile2;
char buffer[256];

pFile=fopen("myfile.txt", "r");
pFile2=fopen("myfile2.txt", "a");
if(pFile==NULL) {
    perror("Error opening file.");
}
else {
    while(fgets(buffer, sizeof(buffer), pFile)) {
        fprintf(pFile2, "%s", buffer);
    }
}
fclose(pFile);
fclose(pFile2);

You can use the line below which goes into a closure (viewDidLoad, didLayOutSubViews, etc):

self.view.backgroundColor = .redColor()

EDIT Swift 3:

view.backgroundColor = .red

MYISAM:

1. MYISAM supports Table-level Locking
2. MyISAM designed for need of speed
3. MyISAM does not support foreign keys hence we call MySQL with MYISAM is DBMS
4. MyISAM stores its tables, data and indexes in diskspace using separate three different files. (tablename.FRM, tablename.MYD, tablename.MYI)
5. MYISAM not supports transaction. You cannot commit and rollback with MYISAM. Once you issue a command it’s done.
6. MYISAM supports fulltext search
7. You can use MyISAM, if the table is more static with lots of select and less update and delete.

INNODB:

1. InnoDB supports Row-level Locking
2. InnoDB designed for maximum performance when processing high volume of data
3. InnoDB support foreign keys hence we call MySQL with InnoDB is RDBMS
4. InnoDB stores its tables and indexes in a tablespace
5. InnoDB supports transaction. You can commit and rollback with InnoDB

Say if you have

/**
 * 
 */
public KKSSocket(final KKSApp app, final String name) {
    this.app = app;
    this.name = name;
    ...
}

then a sub-class named KKSUDPSocket extending KKSSocket could have:

/**
 * @param app
 * @param path
 * @param remoteAddr
 */
public KKSUDPSocket(KKSApp app, String path, KKSAddress remoteAddr) {
    super(app, path, remoteAddr);
}

and

/**
 * @param app
 * @param path
 */
public KKSUDPSocket(KKSApp app, String path) {
    super(app, path);
}

You simply pass the arguments up the constructor chain, like method calls to super classes, but using super(...) which references the super-class constructor and passes in the given args.

You can also do like this,

 <form method='POST'>
    {{form1.as_p}}
    <button type="submit" name="btnform1">Save Changes</button>
    </form>
    <form method='POST'>
    {{form2.as_p}}
    <button type="submit" name="btnform2">Save Changes</button>
    </form>

CODE

if request.method=='POST' and 'btnform1' in request.POST:
    do something...
if request.method=='POST' and 'btnform2' in request.POST:
    do something...

Try this

try {
        reader = new BufferedReader(new InputStreamReader(in,"UTF-8"));
    } catch (UnsupportedEncodingException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
      String line="";
      String s ="";
   try 
   {
       line = reader.readLine();
   } 
   catch (IOException e) 
   {
       e.printStackTrace();
   }
      while (line != null) 
      {
       s = s + line;
       s =s+"\n";
       try 
       {
           line = reader.readLine();
       } 
       catch (IOException e) 
       {
           e.printStackTrace();
       }
    }
    tv.setText(""+s);
  }

If you have pip install and you want to see what packages have been installed with your installer tools you can simply call this:

pip freeze

It will also include version numbers for the installed packages.

Update

pip has been updated to also produce the same output as pip freeze by calling:

pip list

Note

The output from pip list is formatted differently, so if you have some shell script that parses the output (maybe to grab the version number) of freeze and want to change your script to call list, you'll need to change your parsing code.

In my case, this was due to using Integrated Windows Authentication in my data sources while developing reports locally, however once they made it to the report manager, the authentication was broke because the site wasn't properly passing along my credentials.

• The simple fix is to hardcode a username/password into your datasource.
• The harder fix is to properly impersonate/delegate your windows credentials through the report manager, to the underlying datasource.

Depending on what you want the file to contain:

• touch /path/to/file for an empty file

• somecommand > /path/to/file for a file containing the output of some command.

    eg: grep --help > randomtext.txt
        echo "This is some text" > randomtext.txt
  

• nano /path/to/file or vi /path/to/file (or any other editor emacs,gedit etc)
  It either opens the existing one for editing or creates & opens the empty file to enter, if it doesn't exist

Create the file using cat

$ cat > myfile.txt

Now, just type whatever you want in the file:

Hello World!

CTRL-D to save and exit

There are several possible solutions:

Create an empty file

touch file

>file

echo -n > file

printf '' > file

The echo version will work only if your version of echo supports the -n switch to suppress newlines. This is a non-standard addition. The other examples will all work in a POSIX shell.

Create a file containing a newline and nothing else

echo '' > file

printf '\n' > file

This is a valid "text file" because it ends in a newline.

Write text into a file

"$EDITOR" file

echo 'text' > file

cat > file <<END \
text
END

printf 'text\n' > file

These are equivalent. The $EDITOR command assumes that you have an interactive text editor defined in the EDITOR environment variable and that you interactively enter equivalent text. The cat version presumes a literal newline after the \ and after each other line. Other than that these will all work in a POSIX shell.

Of course there are many other methods of writing and creating files, too.

A small drawback in Marc's answer is that both datefields have been typecast, meaning you'll be unable to leverage any indexes.

So, if there is a need to write a query that can benefit from an index on a date field, then the following (rather convoluted) approach is necessary.

• The indexed datefield (call it DF1) must be untouched by any kind of function.
• So you have to compare DF1 to the full range of datetime values for the day of DF2.
• That is from the date-part of DF2, to the date-part of the day after DF2.
• I.e. (DF1 >= CAST(DF2 AS DATE)) AND (DF1 < DATEADD(dd, 1, CAST(DF2 AS DATE)))
• NOTE: It is very important that the comparison is >= (equality allowed) to the date of DF2, and (strictly) < the day after DF2. Also the BETWEEN operator doesn't work because it permits equality on both sides.

PS: Another means of extracting the date only (in older versions of SQL Server) is to use a trick of how the date is represented internally.

• Cast the date as a float.
• Truncate the fractional part
• Cast the value back to a datetime
• I.e. CAST(FLOOR(CAST(DF2 AS FLOAT)) AS DATETIME)

You can use:

npm show {pkg} version

(so npm show express version will return now 3.0.0rc3).

If none of those answers are working for you, try this. Add a submit button before the one that actually submits the form and just do nothing with the event.

HTML

<!-- The following button is meant to do nothing. This button will catch the "enter" key press and stop it's propagation. -->
<button type="submit" id="EnterKeyIntercepter" style="cursor: auto; outline: transparent;"></button>

JavaScript

$('#EnterKeyIntercepter').click((event) => {
    event.preventDefault(); //The buck stops here.
    /*If you don't know what this if statement does, just delete it.*/
    if (process.env.NODE_ENV !== 'production') {
        console.log("The enter key was pressed and captured by the mighty Enter Key Inceptor (¬¦_¦)");
    }
});

To get cell column name as well as cell value :

List<JObject> dataList = new List<JObject>();

for (int i = 0; i < dataTable.Rows.Count; i++)
{
    JObject eachRowObj = new JObject();

    for (int j = 0; j < dataTable.Columns.Count; j++)
    {
        string key = Convert.ToString(dataTable.Columns[j]);
        string value = Convert.ToString(dataTable.Rows[i].ItemArray[j]);

        eachRowObj.Add(key, value);

    }

    dataList.Add(eachRowObj);

}

Given three tasks - FeedCat(), SellHouse() and BuyCar(), there are two interesting cases: either they all complete synchronously (for some reason, perhaps caching or an error), or they don't.

Let's say we have, from the question:

Task<string> DoTheThings() {
    Task<Cat> x = FeedCat();
    Task<House> y = SellHouse();
    Task<Tesla> z = BuyCar();
    // what here?
}

Now, a simple approach would be:

Task.WhenAll(x, y, z);

but ... that isn't convenient for processing the results; we'd typically want to await that:

async Task<string> DoTheThings() {
    Task<Cat> x = FeedCat();
    Task<House> y = SellHouse();
    Task<Tesla> z = BuyCar();

    await Task.WhenAll(x, y, z);
    // presumably we want to do something with the results...
    return DoWhatever(x.Result, y.Result, z.Result);
}

but this does lots of overhead and allocates various arrays (including the params Task[] array) and lists (internally). It works, but it isn't great IMO. In many ways it is simpler to use an async operation and just await each in turn:

async Task<string> DoTheThings() {
    Task<Cat> x = FeedCat();
    Task<House> y = SellHouse();
    Task<Tesla> z = BuyCar();

    // do something with the results...
    return DoWhatever(await x, await y, await z);
}

Contrary to some of the comments above, using await instead of Task.WhenAll makes no difference to how the tasks run (concurrently, sequentially, etc). At the highest level, Task.WhenAll predates good compiler support for async/await, and was useful when those things didn't exist. It is also useful when you have an arbitrary array of tasks, rather than 3 discreet tasks.

But: we still have the problem that async/await generates a lot of compiler noise for the continuation. If it is likely that the tasks might actually complete synchronously, then we can optimize this by building in a synchronous path with an asynchronous fallback:

Task<string> DoTheThings() {
    Task<Cat> x = FeedCat();
    Task<House> y = SellHouse();
    Task<Tesla> z = BuyCar();

    if(x.Status == TaskStatus.RanToCompletion &&
       y.Status == TaskStatus.RanToCompletion &&
       z.Status == TaskStatus.RanToCompletion)
        return Task.FromResult(
          DoWhatever(a.Result, b.Result, c.Result));
       // we can safely access .Result, as they are known
       // to be ran-to-completion

    return Awaited(x, y, z);
}

async Task Awaited(Task<Cat> a, Task<House> b, Task<Tesla> c) {
    return DoWhatever(await x, await y, await z);
}

This "sync path with async fallback" approach is increasingly common especially in high performance code where synchronous completions are relatively frequent. Note it won't help at all if the completion is always genuinely asynchronous.

Additional things that apply here:

1. with recent C#, a common pattern is for the async fallback method is commonly implemented as a local function:

   Task<string> DoTheThings() {
       async Task<string> Awaited(Task<Cat> a, Task<House> b, Task<Tesla> c) {
           return DoWhatever(await a, await b, await c);
       }
       Task<Cat> x = FeedCat();
       Task<House> y = SellHouse();
       Task<Tesla> z = BuyCar();
   
       if(x.Status == TaskStatus.RanToCompletion &&
          y.Status == TaskStatus.RanToCompletion &&
          z.Status == TaskStatus.RanToCompletion)
           return Task.FromResult(
             DoWhatever(a.Result, b.Result, c.Result));
          // we can safely access .Result, as they are known
          // to be ran-to-completion
   
       return Awaited(x, y, z);
   }
   

2. prefer ValueTask<T> to Task<T> if there is a good chance of things ever completely synchronously with many different return values:

   ValueTask<string> DoTheThings() {
       async ValueTask<string> Awaited(ValueTask<Cat> a, Task<House> b, Task<Tesla> c) {
           return DoWhatever(await a, await b, await c);
       }
       ValueTask<Cat> x = FeedCat();
       ValueTask<House> y = SellHouse();
       ValueTask<Tesla> z = BuyCar();
   
       if(x.IsCompletedSuccessfully &&
          y.IsCompletedSuccessfully &&
          z.IsCompletedSuccessfully)
           return new ValueTask<string>(
             DoWhatever(a.Result, b.Result, c.Result));
          // we can safely access .Result, as they are known
          // to be ran-to-completion
   
       return Awaited(x, y, z);
   }
   

3. if possible, prefer IsCompletedSuccessfully to Status == TaskStatus.RanToCompletion; this now exists in .NET Core for Task, and everywhere for ValueTask<T>

Yes there still is no API for this (2.1). But it seemed like at WWDC a lot of people were already interested in the functionality (including myself) and the recommendation was to go to the below site and create a feature request for this. If there is enough of an interest, they might end up moving the ICal.framework to the public SDK.

If you are using Chrome. try some other browser. there where previous posts on this issue saying that phpmyadmin didnot provide privileges for root on chrome.

or try this

name: root

password: password

I coded up an equivalent C program to experiment, and I can confirm this strange behaviour. What's more, gcc believes the 64-bit integer (which should probably be a size_t anyway...) to be better, as using uint_fast32_t causes gcc to use a 64-bit uint.

I did a bit of mucking around with the assembly:
Simply take the 32-bit version, replace all 32-bit instructions/registers with the 64-bit version in the inner popcount-loop of the program. Observation: the code is just as fast as the 32-bit version!

This is obviously a hack, as the size of the variable isn't really 64 bit, as other parts of the program still use the 32-bit version, but as long as the inner popcount-loop dominates performance, this is a good start.

I then copied the inner loop code from the 32-bit version of the program, hacked it up to be 64 bit, fiddled with the registers to make it a replacement for the inner loop of the 64-bit version. This code also runs as fast as the 32-bit version.

My conclusion is that this is bad instruction scheduling by the compiler, not actual speed/latency advantage of 32-bit instructions.

(Caveat: I hacked up assembly, could have broken something without noticing. I don't think so.)

I use SchemaBank to version control all my database schema changes:

• from day 1, I import my db schema dump into it
• i started to change my schema design using a web browser (because they are SaaS / cloud-based)
• when i want to update my db server, i generate the change (SQL) script from it and apply to the db. In Schemabank, they mandate me to commit my work as a version before I can generate an update script. I like this kind of practice so that I can always trace back when I need to.

Our team rule is NEVER touch the db server directly without storing the design work first. But it happens, somebody might be tempted to break the rule, in sake of convenient. We would import the schema dump again into schemabank and let it do the diff and bash someone if a discrepancy is found. Although we could generate the alter scripts from it to make our db and schema design in sync, we just hate that.

By the way, they also let us create branches within the version control tree so that I can maintain one for staging and one for production. And one for coding sandbox.

A pretty neat web-based schema design tool with version control n change management.

Assuming your row number is in B1, you can use INDIRECT:

=INDIRECT("A" & B1)

This takes a cell reference as a string (in this case, the concatenation of A and the value of B1 - 5), and returns the value at that cell.

As pointed out by Aaron Hall's comment:

Since you can't subclass NoneType and since None is a singleton, isinstance should not be used to detect None - instead you should do as the accepted answer says, and use is None or is not None.

Original Answer:

The simplest way however, without the extra line in addition to cardamom's answer is probably:
isinstance(x, type(None))

So how can I question a variable that is a NoneType? I need to use if method

Using isinstance() does not require an is within the if-statement:

if isinstance(x, type(None)): 
    #do stuff

Additional information
You can also check for multiple types in one isinstance() statement as mentioned in the documentation. Just write the types as a tuple.

isinstance(x, (type(None), bytes))

Thank you everyone, for all your precise replys.

Using the svg in a shadow dom, I add the 3 linear gradients I need within the svg, inside a . I place the css fill rule on the web component and the inheritance od fill does the job.

There are several options, including using the method you demonstrate, With, and using a variable.

My preference is option 4 below: Dim a variable of type Worksheet and store the worksheet and call the methods on the variable or pass it to functions, however any of the options work.

Sub Test()
  Dim SheetName As String
  Dim SearchText As String
  Dim FoundRange As Range

  SheetName = "test"      
  SearchText = "abc"

  ' 0. If you know the sheet is the ActiveSheet, you can use if directly.
  Set FoundRange = ActiveSheet.UsedRange.Find(What:=SearchText)
  ' Since I usually have a lot of Subs/Functions, I don't use this method often.
  ' If I do, I store it in a variable to make it easy to change in the future or
  ' to pass to functions, e.g.: Set MySheet = ActiveSheet
  ' If your methods need to work with multiple worksheets at the same time, using
  ' ActiveSheet probably isn't a good idea and you should just specify the sheets.

  ' 1. Using Sheets or Worksheets (Least efficient if repeating or calling multiple times)
  Set FoundRange = Sheets(SheetName).UsedRange.Find(What:=SearchText)
  Set FoundRange = Worksheets(SheetName).UsedRange.Find(What:=SearchText)

  ' 2. Using Named Sheet, i.e. Sheet1 (if Worksheet is named "Sheet1"). The
  ' sheet names use the title/name of the worksheet, however the name must
  ' be a valid VBA identifier (no spaces or special characters. Use the Object
  ' Browser to find the sheet names if it isn't obvious. (More efficient than #1)
  Set FoundRange = Sheet1.UsedRange.Find(What:=SearchText)

  ' 3. Using "With" (more efficient than #1)
  With Sheets(SheetName)
    Set FoundRange = .UsedRange.Find(What:=SearchText)
  End With
  ' or possibly...
  With Sheets(SheetName).UsedRange
    Set FoundRange = .Find(What:=SearchText)
  End With

  ' 4. Using Worksheet variable (more efficient than 1)
  Dim MySheet As Worksheet
  Set MySheet = Worksheets(SheetName)
  Set FoundRange = MySheet.UsedRange.Find(What:=SearchText)

  ' Calling a Function/Sub
  Test2 Sheets(SheetName) ' Option 1
  Test2 Sheet1 ' Option 2
  Test2 MySheet ' Option 4

End Sub

Sub Test2(TestSheet As Worksheet)
    Dim RowIndex As Long
    For RowIndex = 1 To TestSheet.UsedRange.Rows.Count
        If TestSheet.Cells(RowIndex, 1).Value = "SomeValue" Then
            ' Do something
        End If
    Next RowIndex
End Sub

Working solution ~2018

I've found that, providing you have an access token, you can perform the following request in your browser:

https://api.instagram.com/v1/users/self?access_token=[VALUE]

In fact, access token contain the User ID (the first segment of the token):

<user-id>.1677aaa.aaa042540a2345d29d11110545e2499

You can get an access token by using this tool provided by Pixel Union.

This is a very common issue.

One solution is to kill adb server and restart it through command prompt. Sometimes this may not help out.

Just go to Window Task Manager to kill adb process and restart Eclipse.

Will work perfect :)

if all you need is the names, use xpath instead. No need to do the iteration yourself and check for null.

string xml = @"
<root>
    <Employee name=""an"" />
    <Employee name=""nobyd"" />
    <Employee/>
</root>
";

var doc = new XmlDocument();

//doc.Load(path);
doc.LoadXml(xml);

var names = doc.SelectNodes("//Employee/@name");

I prefer you to use below function that is ES6 style:

getQueryStringParams = query => {
    return query
        ? (/^[?#]/.test(query) ? query.slice(1) : query)
            .split('&')
            .reduce((params, param) => {
                    let [key, value] = param.split('=');
                    params[key] = value ? decodeURIComponent(value.replace(/\+/g, ' ')) : '';
                    return params;
                }, {}
            )
        : {}
};

Oh - the ugliness of Windows... Order of includes are important here. You need to include winsock2.h before windows.h. Since windows.h is probably included from your precompiled header (stdafx.h), you will need to include winsock2.h from there:

#include <winsock2.h>
#include <windows.h>

Here's a query to update a table based on a comparison of another table. If record is not found in tableB, it will update the "active" value to "n". If it's found, will set the value to NULL

UPDATE tableA
LEFT JOIN tableB ON tableA.id = tableB.id
SET active = IF(tableB.id IS NULL, 'n', NULL)";

Hope this helps someone else.

$data = array();
foreach ($request->planes as $plan) {
 $data_plan = array($plan => array('dia' => $request->dia[$plan] ) );

With C++17 str::string receives data() overload that returns a pointer to modifieable buffer so string can be used in strtok directly without any hacks:

#include <string>
#include <iostream>
#include <cstring>
#include <cstdlib>

int main()
{
    ::std::string text{"pop dop rop"};
    char const * const psz_delimiter{" "};
    char * psz_token{::std::strtok(text.data(), psz_delimiter)};
    while(nullptr != psz_token)
    {
        ::std::cout << psz_token << ::std::endl;
        psz_token = std::strtok(nullptr, psz_delimiter);
    }
    return EXIT_SUCCESS;
}

output

pop
dop
rop

Here's a batch file, called base64encode.bat, that encodes base64.

@echo off
if not "%1" == "" goto :arg1exists
echo usage: base64encode input-file [output-file]
goto :eof
:arg1exists
set base64out=%2
if "%base64out%" == "" set base64out=con 
(
  set base64tmp=base64.tmp
  certutil -encode "%1" %base64tmp% > nul
  findstr /v /c:- %base64tmp%
  erase %base64tmp%
) > %base64out%

After reading the documentation: http://momentjs.com/docs/#/displaying/difference/, you have to consider the diff function like a minus operator.

                   // today < future (31/01/2014)
today.diff(future) // today - future < 0
future.diff(today) // future - today > 0

Therefore, you have to reverse your condition.

If you want to check that all is fine, you can add an extra parameter to the function:

moment().diff(SpecialTo, 'days') // -8 (days)

dynamic MyDynamic = new System.Dynamic.ExpandoObject();
MyDynamic.A = "A";
MyDynamic.B = "B";
MyDynamic.C = "C";
MyDynamic.Number = 12;
MyDynamic.MyMethod = new Func<int>(() => 
{ 
    return 55; 
});
Console.WriteLine(MyDynamic.MyMethod());

Read more about ExpandoObject class and for more samples: Represents an object whose members can be dynamically added and removed at run time.

If you we are doing all above steps that may be confused and our problem is just missing tools.jre so just add tools.jre by the following steps and problem is solved.

Step 1 : In eclipse go to Windows -> preferences

Step 2 : Java -> Installed JREs (Double click on it)

Step 3 : Click Edit button -> Click Add External JARs

Step 4 : Now select tools.jar path

now apply changes and it works fine.

Here is screenshoot

Have you tried the SVG text element?

.append("text").text(function(d, i) { return d[whichevernode];})

rect element doesn't permit text element inside of it. It only allows descriptive elements (<desc>, <metadata>, <title>) and animation elements (<animate>, <animatecolor>, <animatemotion>, <animatetransform>, <mpath>, <set>)

Append the text element as a sibling and work on positioning.

UPDATE

Using g grouping, how about something like this? fiddle

You can certainly move the logic to a CSS class you can append to, remove from the group (this.parentNode)

Not an answer to the very question but perhaps an idea for the underlying task:

When your site logic should not show a certain element, you could insert an invisible "flag" element that you check for.

if condition
    renderElement()
else
    renderElementNotShownFlag() // used by Selenium test

Have a look at Neon (4.6) M6 - New and Noteworthy, the milestone release contains some automatic scaling for images (e.g. for toolbar).

SWT provides resolution-based auto-scaling

SWT now automatically scales images on high-DPI monitors on Windows and Linux, similar to the Mac's Retina support on OS X. In the absence of high-resolution images, SWT will auto-scale the available images to ensure that SWT-based applications like Eclipse are scaled proportionately to the resolution of the monitor.

This feature can be disabled on Windows and GTK by setting this VM argument to false in eclipse.ini or on the command line after -vmargs:

-Dswt.enable.autoScale=false

Auto-scaling cannot be disabled on the Mac as it is provided by the OS.

Caveats: We're aware that some scaled images look bad at scale factors less than 200%. This will be improved in M7. Furthermore, we're working on support for high-DPI images in Platform UI, so that plug-in providers can add high-DPI icons without doing any code changes.

Or maybe this helps, in Eclipse Mars API for high resolution was added

New APIs have been added to provide support for rendering high-resolution images on high-DPI monitors. Two constructors have been added to the Image class. They accept image-provider callbacks that allow clients to supply resolution-dependent versions of images:

public interface ImageDataProvider {
  public ImageData getImageData (int zoom);
}
public interface ImageFileNameProvider {
  public String getImagePath (int zoom);
}

Depending on the user's monitor configuration, SWT will request images with the corresponding zoom level. Here's an example that displays 3 original images, followed by variants whose resolution changes depending your monitor's resolution: Snippet367.java.

Note that this is just the first step to support high-resolution images in SWT and Eclipse-based applications. Work is underway to adopt the new APIs in the platform. Futhermore, more work in SWT is required to properly support drawing into high-resolution images via GC.

• Open Task Manager

• Find and kill Skype... apps

Restart WampServer and it should work

In Sql when any word contain @ sign it means it is variable and we use this variable to set value in it and use it on number area on the same sql script because it is only restricted on the single script while you can declare lot of variables of same type and name on many script. We use this variable in stored procedure lot because stored procedure are pre-compiled queries and we can pass values in these variable from script, desktop and websites for further information read Declare Local Variable, Sql Stored Procedure and sql injections.

Also read Protect from sql injection it will guide how you can protect your database.

Hope it help you to understand also any question comment me.

Three years later, I ran into the same problem. Here's my solution, everybody feel free to cut-n-paste. The simplest things keep us up all night! Running on an ATMega, and Adafruit Feather M0:

void setup() {
  // turn on Serial so we can see...
  Serial.begin(9600);

  // the culprit:
  uint8_t my_str[6];    // an array big enough for a 5 character string

  // give it something so we can see what it's doing
  my_str[0] = 'H';
  my_str[1] = 'e';
  my_str[2] = 'l';
  my_str[3] = 'l';
  my_str[4] = 'o';
  my_str[5] = 0;  // be sure to set the null terminator!!!

  // can we see it?
  Serial.println((char*)my_str);

  // can we do logical operations with it as-is?
  Serial.println((char*)my_str == 'Hello');

  // okay, it can't; wrong data type (and no terminator!), so let's do this:
  String str((char*)my_str);

  // can we see it now?
  Serial.println(str);

  // make comparisons
  Serial.println(str == 'Hello');

  // one more time just because
  Serial.println(str == "Hello");

  // one last thing...!
  Serial.println(sizeof(str));
}

void loop() {
  // nothing
}

And we get:

Hello    // as expected
0        // no surprise; wrong data type and no terminator in comparison value
Hello    // also, as expected
1        // YAY!
1        // YAY!
6        // as expected

Hope this helps someone!

Try the plyr package:

rbind.fill(a,b,c)

addition to the previous answer add file path directory for the write operation

 fs.writeFile(path.join(__dirname,jsonPath), JSON.stringify(newFileData), function (err) {}

As suggested in other answers it's probably easiest to "POST" the form data to the controller. If you need to pass an entire Model/Form you can easily do this with serialize() e.g.

$('#myform').on('submit', function(e){
    e.preventDefault();

    var formData = $(this).serialize();

    $.post('/student/update', formData, function(response){
         //Do something with response
    });
});

So your controller could have a view model as the param e.g.

 [HttpPost]
 public JsonResult Update(StudentViewModel studentViewModel)
 {}

Alternatively if you just want to post some specific values you can do:

$('#myform').on('submit', function(e){
    e.preventDefault();

    var studentId = $(this).find('#Student_StudentId');
    var isActive = $(this).find('#Student_IsActive');

    $.post('/my/url', {studentId : studentId, isActive : isActive}, function(response){
         //Do something with response
    });
});

With a controller like:

     [HttpPost]
     public JsonResult Update(int studentId, bool isActive)
     {}

Try this:

$(document).ready(function(){
    var yourArray = [];
    $("span.HOEnZb").find("div").each(function(){
        if(($.trim($(this).text()).length>0)){
         yourArray.push($(this).text());
        }
    });
});

DEMO

To put it exactly INTO input as it is shown on the following image:

I found the following approach:

.asterisk_input::after {
content:" *"; 
color: #e32;
position: absolute; 
margin: 0px 0px 0px -20px; 
font-size: xx-large; 
padding: 0 5px 0 0; }

 <form>
    <div>              
        <input type="text" size="15" />                                 
        <span class="asterisk_input">  </span>            
    </div>            
</form> 

Site on which I work is coded using fixed layout so it was ok for me.

I'm not sure that that it's good for liquid design.

You can do this with jQuery's .attr function, which will set attributes. Removing them is done via the .removeAttr function.

//.attr()
$("element").attr("id", "newId");
$("element").attr("disabled", true);

//.removeAttr()
$("element").removeAttr("id");
$("element").removeAttr("disabled");

Google Maps JavaScript API v2 was deprecated in 2011. It is not available anymore.

I had the same problem in Visual Studio Pro 2017: missing MSVCP120.dll file in Release mode and missing MSVCP120d.dll file in Debug mode. I installed Visual C++ Redistributable Packages for Visual Studio 2013 and Update for Visual C++ 2013 and Visual C++ Redistributable Package as suggested here Microsoft answer this fixed the release mode. For the debug mode what eventually worked was to copy msvcp120d.dll and msvcr120d.dll from a different computer (with Visual studio 2013) into C:\Windows\System32

<p:commandXxx process> <p:ajax process> <f:ajax execute>

The process attribute is server side and can only affect UIComponents implementing EditableValueHolder (input fields) or ActionSource (command fields). The process attribute tells JSF, using a space-separated list of client IDs, which components exactly must be processed through the entire JSF lifecycle upon (partial) form submit.

JSF will then apply the request values (finding HTTP request parameter based on component's own client ID and then either setting it as submitted value in case of EditableValueHolder components or queueing a new ActionEvent in case of ActionSource components), perform conversion, validation and updating the model values (EditableValueHolder components only) and finally invoke the queued ActionEvent (ActionSource components only). JSF will skip processing of all other components which are not covered by process attribute. Also, components whose rendered attribute evaluates to false during apply request values phase will also be skipped as part of safeguard against tampered requests.

Note that it's in case of ActionSource components (such as <p:commandButton>) very important that you also include the component itself in the process attribute, particularly if you intend to invoke the action associated with the component. So the below example which intends to process only certain input component(s) when a certain command component is invoked ain't gonna work:

<p:inputText id="foo" value="#{bean.foo}" />
<p:commandButton process="foo" action="#{bean.action}" />

It would only process the #{bean.foo} and not the #{bean.action}. You'd need to include the command component itself as well:

<p:inputText id="foo" value="#{bean.foo}" />
<p:commandButton process="@this foo" action="#{bean.action}" />

Or, as you apparently found out, using @parent if they happen to be the only components having a common parent:

<p:panel><!-- Type doesn't matter, as long as it's a common parent. -->
    <p:inputText id="foo" value="#{bean.foo}" />
    <p:commandButton process="@parent" action="#{bean.action}" />
</p:panel>

Or, if they both happen to be the only components of the parent UIForm component, then you can also use @form:

<h:form>
    <p:inputText id="foo" value="#{bean.foo}" />
    <p:commandButton process="@form" action="#{bean.action}" />
</h:form>

This is sometimes undesirable if the form contains more input components which you'd like to skip in processing, more than often in cases when you'd like to update another input component(s) or some UI section based on the current input component in an ajax listener method. You namely don't want that validation errors on other input components are preventing the ajax listener method from being executed.

Then there's the @all. This has no special effect in process attribute, but only in update attribute. A process="@all" behaves exactly the same as process="@form". HTML doesn't support submitting multiple forms at once anyway.

There's by the way also a @none which may be useful in case you absolutely don't need to process anything, but only want to update some specific parts via update, particularly those sections whose content doesn't depend on submitted values or action listeners.

Noted should be that the process attribute has no influence on the HTTP request payload (the amount of request parameters). Meaning, the default HTML behavior of sending "everything" contained within the HTML representation of the <h:form> will be not be affected. In case you have a large form, and want to reduce the HTTP request payload to only these absolutely necessary in processing, i.e. only these covered by process attribute, then you can set the partialSubmit attribute in PrimeFaces Ajax components as in <p:commandXxx ... partialSubmit="true"> or <p:ajax ... partialSubmit="true">. You can also configure this 'globally' by editing web.xml and add

<context-param>
    <param-name>primefaces.SUBMIT</param-name>
    <param-value>partial</param-value>
</context-param>

Alternatively, you can also use <o:form> of OmniFaces 3.0+ which defaults to this behavior.

The standard JSF equivalent to the PrimeFaces specific process is execute from <f:ajax execute>. It behaves exactly the same except that it doesn't support a comma-separated string while the PrimeFaces one does (although I personally recommend to just stick to space-separated convention), nor the @parent keyword. Also, it may be useful to know that <p:commandXxx process> defaults to @form while <p:ajax process> and <f:ajax execute> defaults to @this. Finally, it's also useful to know that process supports the so-called "PrimeFaces Selectors", see also How do PrimeFaces Selectors as in update="@(.myClass)" work?

<p:commandXxx update> <p:ajax update> <f:ajax render>

The update attribute is client side and can affect the HTML representation of all UIComponents. The update attribute tells JavaScript (the one responsible for handling the ajax request/response), using a space-separated list of client IDs, which parts in the HTML DOM tree need to be updated as response to the form submit.

JSF will then prepare the right ajax response for that, containing only the requested parts to update. JSF will skip all other components which are not covered by update attribute in the ajax response, hereby keeping the response payload small. Also, components whose rendered attribute evaluates to false during render response phase will be skipped. Note that even though it would return true, JavaScript cannot update it in the HTML DOM tree if it was initially false. You'd need to wrap it or update its parent instead. See also Ajax update/render does not work on a component which has rendered attribute.

Usually, you'd like to update only the components which really need to be "refreshed" in the client side upon (partial) form submit. The example below updates the entire parent form via @form:

<h:form>
    <p:inputText id="foo" value="#{bean.foo}" required="true" />
    <p:message id="foo_m" for="foo" />
    <p:inputText id="bar" value="#{bean.bar}" required="true" />
    <p:message id="bar_m" for="bar" />
    <p:commandButton action="#{bean.action}" update="@form" />
</h:form>

(note that process attribute is omitted as that defaults to @form already)

Whilst that may work fine, the update of input and command components is in this particular example unnecessary. Unless you change the model values foo and bar inside action method (which would in turn be unintuitive in UX perspective), there's no point of updating them. The message components are the only which really need to be updated:

<h:form>
    <p:inputText id="foo" value="#{bean.foo}" required="true" />
    <p:message id="foo_m" for="foo" />
    <p:inputText id="bar" value="#{bean.bar}" required="true" />
    <p:message id="bar_m" for="bar" />
    <p:commandButton action="#{bean.action}" update="foo_m bar_m" />
</h:form>

However, that gets tedious when you have many of them. That's one of the reasons why PrimeFaces Selectors exist. Those message components have in the generated HTML output a common style class of ui-message, so the following should also do:

<h:form>
    <p:inputText id="foo" value="#{bean.foo}" required="true" />
    <p:message id="foo_m" for="foo" />
    <p:inputText id="bar" value="#{bean.bar}" required="true" />
    <p:message id="bar_m" for="bar" />
    <p:commandButton action="#{bean.action}" update="@(.ui-message)" />
</h:form>

(note that you should keep the IDs on message components, otherwise @(...) won't work! Again, see How do PrimeFaces Selectors as in update="@(.myClass)" work? for detail)

The @parent updates only the parent component, which thus covers the current component and all siblings and their children. This is more useful if you have separated the form in sane groups with each its own responsibility. The @this updates, obviously, only the current component. Normally, this is only necessary when you need to change one of the component's own HTML attributes in the action method. E.g.

<p:commandButton action="#{bean.action}" update="@this" 
    oncomplete="doSomething('#{bean.value}')" />

Imagine that the oncomplete needs to work with the value which is changed in action, then this construct wouldn't have worked if the component isn't updated, for the simple reason that oncomplete is part of generated HTML output (and thus all EL expressions in there are evaluated during render response).

The @all updates the entire document, which should be used with care. Normally, you'd like to use a true GET request for this instead by either a plain link (<a> or <h:link>) or a redirect-after-POST by ?faces-redirect=true or ExternalContext#redirect(). In effects, process="@form" update="@all" has exactly the same effect as a non-ajax (non-partial) submit. In my entire JSF career, the only sensible use case I encountered for @all is to display an error page in its entirety in case an exception occurs during an ajax request. See also What is the correct way to deal with JSF 2.0 exceptions for AJAXified components?

The standard JSF equivalent to the PrimeFaces specific update is render from <f:ajax render>. It behaves exactly the same except that it doesn't support a comma-separated string while the PrimeFaces one does (although I personally recommend to just stick to space-separated convention), nor the @parent keyword. Both update and render defaults to @none (which is, "nothing").

You need to use gdb's memory-display commands. The basic one is x, for examine. There's an example on the linked-to page that uses

gdb> x/4xw $sp

to print "four words (w ) of memory above the stack pointer (here, $sp) in hexadecimal (x)". The quotation is slightly paraphrased.

Converting my comment into an answer to complement @Kiran Chala's answer as it seems helpful for the audiences-

When we mark a parameter as optional in the action uri using ? character then we must provide default values to the parameters in the method signature as shown below:

MyMethod(string name = "someDefaultValue", int? Id = null)

Even if you do not have the pid, you can trigger 'wait;' after triggering all background processes. For. eg. in commandfile.sh-

bteq < input_file1.sql > output_file1.sql &
bteq < input_file2.sql > output_file2.sql &
bteq < input_file3.sql > output_file3.sql &
wait

Then when this is triggered, as -

subprocess.call(['sh', 'commandfile.sh'])
print('all background processes done.')

This will be printed only after all the background processes are done.

The closest thing C does to "computing p" in a way that's directly visible to applications is acos(-1) or similar. This is almost always done with polynomial/rational approximations for the function being computed (either in C, or by the FPU microcode).

However, an interesting issue is that computing the trigonometric functions (sin, cos, and tan) requires reduction of their argument modulo 2p. Since 2p is not a diadic rational (and not even rational), it cannot be represented in any floating point type, and thus using any approximation of the value will result in catastrophic error accumulation for large arguments (e.g. if x is 1e12, and 2*M_PI differs from 2p by e, then fmod(x,2*M_PI) differs from the correct value of 2p by up to 1e12*e/p times the correct value of x mod 2p. That is to say, it's completely meaningless.

A correct implementation of C's standard math library simply has a gigantic very-high-precision representation of p hard coded in its source to deal with the issue of correct argument reduction (and uses some fancy tricks to make it not-quite-so-gigantic). This is how most/all C versions of the sin/cos/tan functions work. However, certain implementations (like glibc) are known to use assembly implementations on some cpus (like x86) and don't perform correct argument reduction, leading to completely nonsensical outputs. (Incidentally, the incorrect asm usually runs about the same speed as the correct C code for small arguments.)

Use Test-Path:

if (!(Test-Path $exactadminfile) -and !(Test-Path $userfile)) {
  Write-Warning "$userFile absent from both locations"
}

Placing the above code in your ForEach loop should do what you want

For MongoDB 3.6 and newer:

The $expr operator allows the use of aggregation expressions within the query language, thus you can leverage the use of $strLenCP operator to check the length of the string as follows:

db.usercollection.find({ 
    "name": { "$exists": true },
    "$expr": { "$gt": [ { "$strLenCP": "$name" }, 40 ] } 
})

For MongoDB 3.4 and newer:

You can also use the aggregation framework with the $redact pipeline operator that allows you to proccess the logical condition with the $cond operator and uses the special operations $$KEEP to "keep" the document where the logical condition is true or $$PRUNE to "remove" the document where the condition was false.

This operation is similar to having a $project pipeline that selects the fields in the collection and creates a new field that holds the result from the logical condition query and then a subsequent $match, except that $redact uses a single pipeline stage which is more efficient.

As for the logical condition, there are String Aggregation Operators that you can use $strLenCP operator to check the length of the string. If the length is $gt a specified value, then this is a true match and the document is "kept". Otherwise it is "pruned" and discarded.

Consider running the following aggregate operation which demonstrates the above concept:

db.usercollection.aggregate([
    { "$match": { "name": { "$exists": true } } },
    {
        "$redact": {
            "$cond": [
                { "$gt": [ { "$strLenCP": "$name" }, 40] },
                "$$KEEP",
                "$$PRUNE"
            ]
        }
    },
    { "$limit": 2 }
])

If using $where, try your query without the enclosing brackets:

db.usercollection.find({$where: "this.name.length > 40"}).limit(2);

A better query would be to to check for the field's existence and then check the length:

db.usercollection.find({name: {$type: 2}, $where: "this.name.length > 40"}).limit(2); 

or:

db.usercollection.find({name: {$exists: true}, $where: "this.name.length > 
40"}).limit(2); 

MongoDB evaluates non-$where query operations before $where expressions and non-$where query statements may use an index. A much better performance is to store the length of the string as another field and then you can index or search on it; applying $where will be much slower compared to that. It's recommended to use JavaScript expressions and the $where operator as a last resort when you can't structure the data in any other way, or when you are dealing with a small subset of data.

A different and faster approach that avoids the use of the $where operator is the $regex operator. Consider the following pattern which searches for

db.usercollection.find({"name": {"$type": 2, "$regex": /^.{41,}$/}}).limit(2); 

Note - From the docs:

If an index exists for the field, then MongoDB matches the regular expression against the values in the index, which can be faster than a collection scan. Further optimization can occur if the regular expression is a “prefix expression”, which means that all potential matches start with the same string. This allows MongoDB to construct a “range” from that prefix and only match against those values from the index that fall within that range.

A regular expression is a “prefix expression” if it starts with a caret (^) or a left anchor (\A), followed by a string of simple symbols. For example, the regex /^abc.*/ will be optimized by matching only against the values from the index that start with abc.

Additionally, while /^a/, /^a.*/, and /^a.*$/ match equivalent strings, they have different performance characteristics. All of these expressions use an index if an appropriate index exists; however, /^a.*/, and /^a.*$/ are slower. /^a/ can stop scanning after matching the prefix.

I used   and it is working fine. You could try it. You do not need to use the quotation marks

Try this

  git for-each-ref --format='%(committerdate) %09 %(authorname) %09 %(refname)'

Try passing width=200 as additional paramater when creating the Label.

This should work in creating label with specified width.

If you want to change it later, you can use:

label.config(width=200)

As you want to change the size of font itself you can try:

label.config(font=("Courier", 44))

//Scroll item pos

linearLayoutManager.scrollToPositionWithOffset(pos, 0);

quite possibly the simplest method ...

<?php
$change = array('key1' => $var1, 'key2' => $var2, 'key3' => $var3);
echo json_encode(change);
?>

Then the jquery script ...

<script>
$.get("location.php", function(data){
var duce = jQuery.parseJSON(data);
var art1 = duce.key1;
var art2 = duce.key2;
var art3 = duce.key3;
});
</script>

Sure. Just list the files:

$ svn ci -m "Fixed all those horrible crashes" foo bar baz graphics/logo.png

I'm not aware of a way to tell it to ignore a certain set of files. Of course, if the files you do want to commit are easily listed by the shell, you can use that:

$ svn ci -m "No longer sets printer on fire" printer-driver/*.c

You can also have the svn command read the list of files to commit from a file:

$ svn ci -m "Now works" --targets fix4711.txt

just update classpath 'com.android.tools.build:gradle:X.X.X' in Project Build.Gradle and replace X to the latest version do you have

List<T> has a FindAll method that will do the filtering for you and return a subset of the list.

MSDN has a great code example here: http://msdn.microsoft.com/en-us/library/aa701359(VS.80).aspx

EDIT: I wrote this before I had a good understanding of LINQ and the Where() method. If I were to write this today i would probably use the method Jorge mentions above. The FindAll method still works if you're stuck in a .NET 2.0 environment though.

Since C# 7.0 supports using static directive and Local functions you don't need preprocessor macros for most cases.

Set style= "display:none;". By setting visible=false, it will not render button in the browser. Thus,client side script wont execute.

<asp:Button ID="savebtn" runat="server" OnClick="savebtn_Click" style="display:none" />

html markup should be

<button id="btnsave" onclick="fncsave()">Save</button>

Change javascript to

<script type="text/javascript">
     function fncsave()
     {
        document.getElementById('<%= savebtn.ClientID %>').click();
     }
</script>

as a workaround you can use the stdin device in /dev directory

....| for item in `cat /dev/stdin` ; do echo $item ;done

I'm not quite sure what you're attempting to use the div for, but this is an example with some random text.

Mr_Green gave the correct instructions when he said to add overflow-y: auto as that restricts it to vertical scrolling. This is a JSFiddle example:

The answer I was searching for was answered here: How to use python argparse with args other than sys.argv?

If main.py and parse_args() is written in this way, then the parsing can be done nicely

# main.py
import argparse
def parse_args():
    parser = argparse.ArgumentParser(description="")
    parser.add_argument('--input', default='my_input.txt')
    return parser

def main(args):
    print(args.input)

if __name__ == "__main__":
    parser = parse_args()
    args = parser.parse_args()
    main(args)

Then you can call main() and parse arguments with parser.parse_args(['--input', 'foobar.txt']) to it in another python script:

# temp.py
from main import main, parse_args
parser = parse_args()
args = parser.parse_args([]) # note the square bracket
# to overwrite default, use parser.parse_args(['--input', 'foobar.txt'])
print(args) # Namespace(input='my_input.txt')
main(args)

For those whose want created or modified user detail along with the time using JPA and Spring Data can follow this. You can add @CreatedDate,@LastModifiedDate,@CreatedBy and @LastModifiedBy in the base domain. Mark the base domain with @MappedSuperclass and @EntityListeners(AuditingEntityListener.class) like shown below:

@MappedSuperclass
@EntityListeners(AuditingEntityListener.class)
public class BaseDomain implements Serializable {

    @CreatedDate
    private Date createdOn;

    @LastModifiedDate
    private Date modifiedOn;

    @CreatedBy
    private String createdBy;

    @LastModifiedBy
    private String modifiedBy;

}

Since we marked the base domain with AuditingEntityListener we can tell JPA about currently logged in user. So we need to provide an implementation of AuditorAware and override getCurrentAuditor() method. And inside getCurrentAuditor() we need to return the currently authorized user Id.

public class AuditorAwareImpl implements AuditorAware<String> {
    @Override
    public Optional<String> getCurrentAuditor() {
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        return authentication == null ? Optional.empty() : Optional.ofNullable(authentication.getName());
    }
}

In the above code if Optional is not working you may using older spring data. In that case try changing Optional with String.

Now for enabling the above Audtior implementation use the code below

@Configuration
@EnableJpaAuditing(auditorAwareRef = "auditorAware")
public class JpaConfig {
    @Bean
    public AuditorAware<String> auditorAware() {
        return new AuditorAwareImpl();
    }
}

Now you can extend the BaseDomain class to all of your entity class where you want the created and modified date & time along with user Id

You should put the print function in your view-details.php file and call it once the file is loaded, by either using

<body onload="window.print()"> 

or

$(document).ready(function () { 
  window.print(); 
});

select count(*) from dbo.tablename where address_line_1 LIKE '%[\'']%' {eSCAPE'\'}

I found a workaround for the problem; instead of copy-pasting by hand, use Excel to connect to your database and import the complete table. Then remove the data you are not interested in.

Here are the steps (for Excel 2010)

1. Go to menu Data > Get external data: From other sources > From SQL Server
2. Type the sql server name (and credentials if you don't have Windows authentication on your server) and connect.
3. Select the database and table that contains the data with the newlines and click 'Finish'.
4. Select the destination worksheet and click 'Ok'.

Excel will now import the complete table with the newlines intact.

There is no standard Unix command, AFAIK. I haven't used Sun OS, but on Linux, you can use this:

cat /proc/cpuinfo

Sorry that it is Linux, not Sun OS. There is probably something similar though for Sun OS.

I think most of these solutions are far too complicated. I assume that in your test controller you have this

 @Autowired
 private ObjectMapper objectMapper;

If its a rest service

@Test
public void test() throws Exception {
   mockMvc.perform(post("/person"))
          .contentType(MediaType.APPLICATION_JSON)
          .content(objectMapper.writeValueAsString(new Person()))
          ...etc
}

For spring mvc using a posted form I came up with this solution. (Not really sure if its a good idea yet)

private MultiValueMap<String, String> toFormParams(Object o, Set<String> excludeFields) throws Exception {
    ObjectReader reader = objectMapper.readerFor(Map.class);
    Map<String, String> map = reader.readValue(objectMapper.writeValueAsString(o));

    MultiValueMap<String, String> multiValueMap = new LinkedMultiValueMap<>();
    map.entrySet().stream()
            .filter(e -> !excludeFields.contains(e.getKey()))
            .forEach(e -> multiValueMap.add(e.getKey(), (e.getValue() == null ? "" : e.getValue())));
    return multiValueMap;
}



@Test
public void test() throws Exception {
  MultiValueMap<String, String> formParams = toFormParams(new Phone(), 
  Set.of("id", "created"));

   mockMvc.perform(post("/person"))
          .contentType(MediaType.APPLICATION_FORM_URLENCODED)
          .params(formParams))
          ...etc
}

The basic idea is to - first convert object to json string to get all the field names easily - convert this json string into a map and dump it into a MultiValueMap that spring expects. Optionally filter out any fields you dont want to include (Or you could just annotate fields with @JsonIgnore to avoid this extra step)

exec sp_helptext 'your_sp_name' -- don't forget the quotes

In management studio by default results come in grid view. If you would like to see it in text view go to:

I use the following to turn all error reporting on for MySQLi

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);

*NOTE: don't use this in a production environment.

You can factor out your common logic to a private method, for example called Initialize that gets called from both constructors.

Due to the fact that you want to perform argument validation you cannot resort to constructor chaining.

Example:

public Point2D(double x, double y)
{
    // Contracts

    Initialize(x, y);
}

public Point2D(Point2D point)
{
    if (point == null)
        throw new ArgumentNullException("point");

    // Contracts

    Initialize(point.X, point.Y);
}

private void Initialize(double x, double y)
{
    X = x;
    Y = y;
}

This is probably caused by different python versions installed on your system, i.e. python2 or python3.

Run command $ pip --version and $ pip3 --version to check which pip is from at Python 3x. E.g. you should see version information like below:

pip 19.0.3 from /usr/local/lib/python3.7/site-packages/pip (python 3.7)

Then run the example.py script with below command

$ python3 example.py

I set the content-type in the MarshallingView in the ContentNegotiatingViewResolver bean. It works easily, clean and smoothly:

<property name="defaultViews">

      <constructor-arg>
        <bean class="org.springframework.oxm.xstream.XStreamMarshaller" />     
      </constructor-arg>
      <property name="contentType" value="application/xml;charset=UTF-8" />
    </bean>
  </list>
</property>

Its boils down to this: math.h is from C and was created over 10 years ago. In math.h, due to its primitive nature, the abs() function is "essentially" just for integer types and if you wanted to get the absolute value of a double, you had to use fabs(). When C++ was created it took math.h and made it cmath. cmath is essentially math.h but improved for C++. It improved things like having to distinguish between fabs() and abs, and just made abs() for both doubles and integer types. In summary either: Use math.h and use abs() for integers, fabs() for doubles or use cmath and just have abs for everything (easier and recommended)

Hope this helps anyone who is having the same problem!

You can call up the color picker from any Cocoa application (TextEdit, Mail, Keynote, Pages, etc.) by hitting Shift-Command-C

Just a note: You might have set up your service differently using the forms interface to add a service installer and project installer. In that case replace where it says serviceInstaller.ServiceName with "name from designer".ServiceName.

You also don't need the private members in this case.

Thanks for the help.

Or simply use the JFreechart library - http://www.jfree.org/jfreechart/ .

TL;DR

Use the nargs option or the 'append' setting of the action option (depending on how you want the user interface to behave).

nargs

parser.add_argument('-l','--list', nargs='+', help='<Required> Set flag', required=True)
# Use like:
# python arg.py -l 1234 2345 3456 4567

nargs='+' takes 1 or more arguments, nargs='*' takes zero or more.

append

parser.add_argument('-l','--list', action='append', help='<Required> Set flag', required=True)
# Use like:
# python arg.py -l 1234 -l 2345 -l 3456 -l 4567

With append you provide the option multiple times to build up the list.

Don't use type=list!!! - There is probably no situation where you would want to use type=list with argparse. Ever.

Let's take a look in more detail at some of the different ways one might try to do this, and the end result.

import argparse

parser = argparse.ArgumentParser()

# By default it will fail with multiple arguments.
parser.add_argument('--default')

# Telling the type to be a list will also fail for multiple arguments,
# but give incorrect results for a single argument.
parser.add_argument('--list-type', type=list)

# This will allow you to provide multiple arguments, but you will get
# a list of lists which is not desired.
parser.add_argument('--list-type-nargs', type=list, nargs='+')

# This is the correct way to handle accepting multiple arguments.
# '+' == 1 or more.
# '*' == 0 or more.
# '?' == 0 or 1.
# An int is an explicit number of arguments to accept.
parser.add_argument('--nargs', nargs='+')

# To make the input integers
parser.add_argument('--nargs-int-type', nargs='+', type=int)

# An alternate way to accept multiple inputs, but you must
# provide the flag once per input. Of course, you can use
# type=int here if you want.
parser.add_argument('--append-action', action='append')

# To show the results of the given option to screen.
for _, value in parser.parse_args()._get_kwargs():
    if value is not None:
        print(value)

Here is the output you can expect:

$ python arg.py --default 1234 2345 3456 4567
...
arg.py: error: unrecognized arguments: 2345 3456 4567

$ python arg.py --list-type 1234 2345 3456 4567
...
arg.py: error: unrecognized arguments: 2345 3456 4567

$ # Quotes won't help here...

Takeaways:

• Use nargs or action='append'
  • nargs can be more straightforward from a user perspective, but it can be unintuitive if there are positional arguments because argparse can't tell what should be a positional argument and what belongs to the nargs; if you have positional arguments then action='append' may end up being a better choice.
  • The above is only true if nargs is given '*', '+', or '?'. If you provide an integer number (such as 4) then there will be no problem mixing options with nargs and positional arguments because argparse will know exactly how many values to expect for the option.
• Don't use quotes on the command line¹
• Don't use type=list, as it will return a list of lists
  • This happens because under the hood argparse uses the value of type to coerce each individual given argument you your chosen type, not the aggregate of all arguments.
  • You can use type=int (or whatever) to get a list of ints (or whatever)

¹: I don't mean in general.. I mean using quotes to pass a list to argparse is not what you want.

just re-installed mongo and it worked. No collections lost. Easiest solution atleast for me

Robocopy replaces XCopy in the newer versions of windows

1. Uses Mirroring, XCopy does not
2. Has a /RH option to allow a set time for the copy to run
3. Has a /MON:n option to check differences in files
4. Copies over more file attributes than XCopy

Yes i agree with Mark Setchell, They are both crap. (brought to you by Microsoft)

UPDATE:

XCopy return codes:

0 - Files were copied without error.
1 - No files were found to copy.
2 - The user pressed CTRL+C to terminate xcopy. enough memory or disk space, or you entered an invalid drive name or invalid syntax on the command line.
5 - Disk write error occurred.

Robocopy returns codes:

0 - No errors occurred, and no copying was done. The source and destination directory trees are completely synchronized.
1 - One or more files were copied successfully (that is, new files have arrived).
2 - Some Extra files or directories were detected. No files were copied Examine the output log for details. 
3 - (2+1) Some files were copied. Additional files were present. No failure was encountered.
4 - Some Mismatched files or directories were detected. Examine the output log. Some housekeeping may be needed.
5 - (4+1) Some files were copied. Some files were mismatched. No failure was encountered.
6 - (4+2) Additional files and mismatched files exist. No files were copied and no failures were encountered. This means that the files already exist in the destination directory
7 - (4+1+2) Files were copied, a file mismatch was present, and additional files were present.
8 - Some files or directories could not be copied (copy errors occurred and the retry limit was exceeded). Check these errors further.
16 - Serious error. Robocopy did not copy any files. Either a usage error or an error due to insufficient access privileges on the source or destination directories.

There is more details on Robocopy return values here: http://ss64.com/nt/robocopy-exit.html

The 'c' means it's a character device. tty is a special file representing the 'controlling terminal' for the current process.

Character Devices

Unix supports 'device files', which aren't really files at all, but file-like access points to hardware devices. A 'character' device is one which is interfaced byte-by-byte (as opposed to buffered IO).

TTY

/dev/tty is a special file, representing the terminal for the current process. So, when you echo 1 > /dev/tty, your message ('1') will appear on your screen. Likewise, when you cat /dev/tty, your subsequent input gets duplicated (until you press Ctrl-C).

/dev/tty doesn't 'contain' anything as such, but you can read from it and write to it (for what it's worth). I can't think of a good use for it, but there are similar files which are very useful for simple IO operations (e.g. /dev/ttyS0 is normally your serial port)

This quote is from http://tldp.org/HOWTO/Text-Terminal-HOWTO-7.html#ss7.3 :

/dev/tty stands for the controlling terminal (if any) for the current process. To find out which tty's are attached to which processes use the "ps -a" command at the shell prompt (command line). Look at the "tty" column. For the shell process you're in, /dev/tty is the terminal you are now using. Type "tty" at the shell prompt to see what it is (see manual pg. tty(1)). /dev/tty is something like a link to the actually terminal device name with some additional features for C-programmers: see the manual page tty(4).

Here is the man page: http://linux.die.net/man/4/tty

My 2 cents: the same code works even if iOS:

#include <arpa/inet.h>
#include <sys/socket.h>
#include <netdb.h>
#include <ifaddrs.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <string.h>



#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    showIP();
}



void showIP()
{
    struct ifaddrs *ifaddr, *ifa;
    int family, s;
    char host[NI_MAXHOST];

    if (getifaddrs(&ifaddr) == -1)
    {
        perror("getifaddrs");
        exit(EXIT_FAILURE);
    }


    for (ifa = ifaddr; ifa != NULL; ifa = ifa->ifa_next)
    {
        if (ifa->ifa_addr == NULL)
            continue;

        s=getnameinfo(ifa->ifa_addr,sizeof(struct sockaddr_in),host, NI_MAXHOST, NULL, 0, NI_NUMERICHOST);

        if( /*(strcmp(ifa->ifa_name,"wlan0")==0)&&( */ ifa->ifa_addr->sa_family==AF_INET) // )
        {
            if (s != 0)
            {
                printf("getnameinfo() failed: %s\n", gai_strerror(s));
                exit(EXIT_FAILURE);
            }
            printf("\tInterface : <%s>\n",ifa->ifa_name );
            printf("\t  Address : <%s>\n", host);
        }
    }

    freeifaddrs(ifaddr);
}


@end

I simply removed the test against wlan0 to see data. ps You can remove "family"

text1.setTextColor(Color.parseColor("#000000"));

The simplest and most fun way (imo) is glob

foreach (glob("*.*") as $filename) {
    echo $filename."<br />";
}

But the standard way is to use the directory functions.

if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            echo "filename: .".$file."<br />";
        }
        closedir($dh);
    }
}

There are also the SPL DirectoryIterator methods. If you are interested

True is only valid if you're using the .NET SqlClient library. It isn't valid when using OLEDB. Where SSPI is bvaid in both either you are using .net SqlClient library or OLEDB.

Just use a where clause that won't select any rows:

create table xyz_new as select * from xyz where 1=0;

Limitations

The following things will not be copied to the new table:

• sequences
• triggers
• indexes
• some constraints may not be copied
• materialized view logs

This also does not handle partitions

For me below jquery worked:

changing "body" to document

$(document).on('focus',".datepicker_recurring_start", function(){
    $(this).datepicker();

Note: make sure your id is different for each field

no real explanation is given by Java (in either JavaDoc or much coveted code comments), but looking at the code, it seems that this is magic:

calling stack:

String.indexOf(char[], int, int, char[], int, int, int) line: 1591  
String.indexOf(String, int) line: 1564  
String.indexOf(String) line: 1546   
String.contains(CharSequence) line: 1934    

code:

/**
 * Code shared by String and StringBuffer to do searches. The
 * source is the character array being searched, and the target
 * is the string being searched for.
 *
 * @param   source       the characters being searched.
 * @param   sourceOffset offset of the source string.
 * @param   sourceCount  count of the source string.
 * @param   target       the characters being searched for.
 * @param   targetOffset offset of the target string.
 * @param   targetCount  count of the target string.
 * @param   fromIndex    the index to begin searching from.
 */
static int indexOf(char[] source, int sourceOffset, int sourceCount,
                   char[] target, int targetOffset, int targetCount,
                   int fromIndex) {
  if (fromIndex >= sourceCount) {
        return (targetCount == 0 ? sourceCount : -1);
  }
      if (fromIndex < 0) {
        fromIndex = 0;
      }
  if (targetCount == 0) {//my comment: this is where it returns, the size of the 
    return fromIndex;    // incoming string is 0,  which is passed in as targetCount
  }                      // fromIndex is 0 as well, as the search starts from the 
                         // start of the source string
    ...//the rest of the method 

Use output buffers: http://php.net/manual/de/function.ob-start.php

<?php
    ob_start();
    var_dump($_SERVER) ;
    $dump = ob_get_contents();
    ob_end_clean();

    echo "<pre> $dump </pre>";
?>

Yet another option would be to use Output buffering and convert all the newlines in the dump to <br> elements, e.g.

ob_start();
var_dump($_SERVER) ;
echo nl2br(ob_get_clean());

If you want to do it fast and don't want to lose references and listeners use: .insertAdjacentHTML();

"It does not reparse the element it is being used on and thus it does not corrupt the existing elements inside the element. This, and avoiding the extra step of serialization make it much faster than direct innerHTML manipulation."

Supported on all mainline browsers (IE6+, FF8+,All Others and Mobile): http://caniuse.com/#feat=insertadjacenthtml

Example from https://developer.mozilla.org/en-US/docs/Web/API/Element/insertAdjacentHTML

// <div id="one">one</div>
var d1 = document.getElementById('one');
d1.insertAdjacentHTML('afterend', '<div id="two">two</div>');

// At this point, the new structure is:
// <div id="one">one</div><div id="two">two</div>

Using a typedef avoids having to write struct every time you declare a variable of that type:

struct elem
{
 int i;
 char k;
};
elem user; // compile error!
struct elem user; // this is correct

How do I run an executable JAR file? If you have a jar file called Example.jar, follow these rules:

Open a notepad.exe.
Write : java -jar Example.jar.
Save it with the extension .bat.
Copy it to the directory which has the .jar file.
Double click it to run your .jar file.

To do this using data.table, I found that the following works. Unfortunately, the link does not work anymore, so I used a link for another data set.

library(data.table)
temp <- tempfile()
download.file("https://www.bls.gov/tus/special.requests/atusact_0315.zip", temp)
timeUse <- fread(unzip(temp, files = "atusact_0315.dat"))
rm(temp)

I know this is possible in a single line since you can pass bash scripts to fread, but I am not sure how to download a .zip file, extract, and pass a single file from that to fread.

I feel like $all would be more appropriate in this situation. If you are looking for person that is into sushi you do :

PersonModel.find({ favoriteFood : { $all : ["sushi"] }, ...})

As you might want to filter more your search, like so :

PersonModel.find({ favoriteFood : { $all : ["sushi", "bananas"] }, ...})

$in is like OR and $all like AND. Check this : https://docs.mongodb.com/manual/reference/operator/query/all/

The computer "name" is resolved from the IP address by the underlying DNS (Domain Name System) library of the OS. There's no universal concept of a computer name across OSes, but DNS is generally available. If the computer name hasn't been configured so DNS can resolve it, it isn't available.

import java.net.InetAddress;
import java.net.UnknownHostException;

String hostname = "Unknown";

try
{
    InetAddress addr;
    addr = InetAddress.getLocalHost();
    hostname = addr.getHostName();
}
catch (UnknownHostException ex)
{
    System.out.println("Hostname can not be resolved");
}

React 16.8 + Functional component - useFocus hook

export const useFocus = (): [React.MutableRefObject<HTMLInputElement>, VoidFunction] => {
  const htmlElRef = React.useRef<HTMLInputElement>(null);
  const setFocus = React.useCallback(() => {
    if (htmlElRef.current) htmlElRef.current.focus();
  }, [htmlElRef]);

  return React.useMemo(() => [htmlElRef, setFocus], [htmlElRef, setFocus]);
};

One other answer to the same error message (this just fixed my problem) is that the System drive was low on disk space. Meaning about 700kb free. Deleting a lot of unused stuff on this really old server and then restarting IIS and the website (probably only IIS was necessary) cause the problem to disappear for me.

I'm sure the other answers are more useful for most people, but for a quick fix, just make sure that the System drive has some free space.

This is where the window function row_number() comes in handy:

SELECT s.siteName, s.siteIP, h.date
FROM sites s INNER JOIN
     (select h.*, row_number() over (partition by siteName order by date desc) as seqnum
      from history h
     ) h
    ON s.siteName = h.siteName and seqnum = 1
ORDER BY s.siteName, h.date

3 Steps:

• Open "Repo Browser" (Use Link of yr parent folder) .
• Right click Choose "Add Folder".
• Browse to your folder.

After I accidentally closed this window, I took an hour to find how to bring it back up.

The right answer is indeed: View-->Report Data (ctrl+alt+D)

The tricky part: the 'Report Data' entry does not always appear in the 'View' dropdown. Make sure that you have a report open, and some element of the report selected.

If you're not 'in the report', the entry disappears from the menu.

The proper way as of now is to use a solution recommended by @Roman Kuzmin in comments to @M. Dudley answer:

[IO.File]::WriteAllLines($filename, $content)

(I've also shortened it a bit by stripping unnecessary System namespace clarification - it will be substituted automatically by default.)

In C++, your source files are usually parsed from top to bottom in a single pass, so any variable or function must be declared before they can be used. There are some exceptions to this, like when defining functions inline in a class definition, but that's not the case for your code.

Either move the definition of integrate above the one for getSkewNormal, or add a forward declaration above getSkewNormal:

double integrate (double start, double stop, int numSteps, Evaluatable evalObj);

The same applies for sum.

d = {}
for i in keys:
    d[i] = None

<a href="javascript:void(0)" onclick="$('#myDialog').dialog();">
  Open as dialog
</a>

<div id="myDialog">
I have a dialog!
</div>

See the example I posted on jsbin.com.

A Better Solution for this to make a Class for common Navigation bars

I have 5 Controllers and each controller title is changed to orange color. As each controller has 5 navigation controllers so i had to change every one color either from inspector or from code.

So i made a class instead of changing every one Navigation bar from code i just assign this class and it worked on all 5 controller Code reuse Ability. You just have to assign this class to Each controller and thats it.

import UIKit

   class NabigationBar: UINavigationBar {
      required init?(coder aDecoder: NSCoder) {
       super.init(coder: aDecoder)
    commonFeatures()
 }

   func commonFeatures() {

    self.backgroundColor = UIColor.white;
      UINavigationBar.appearance().titleTextAttributes =     [NSAttributedStringKey.foregroundColor:ColorConstants.orangeTextColor]

 }


  }

You need to add this in your web.config

<system.net>
  <defaultProxy>
    <proxy bypassonlocal="False" usesystemdefault="True" proxyaddress="http://127.0.0.1:8888" />
  </defaultProxy>
</system.net>

1. then Start Fiddler on the WEBSERVER machine.
2. Click Tools | Fiddler Options => Connections => adjust the port as 8888.(allow remote if you need that)
3. Ok, then from file menu, capture the traffic.

That's all, but don't forget to remove the web.config lines after closing the fiddler, because if you don't it will make an error.

The "delete module-info.java at your Project Explorer tab" answer is the easiest and most straightforward answer, but

for those who would want a little more understanding or control of what's happening, the following alternate methods may be desirable;

• make an ever so slightly more realistic application; com.YourCompany.etc or just com.HelloWorld (Project name: com.HelloWorld and class name: HelloWorld)

or

• when creating the java project; when in the Create Java Project dialog, don't choose Finish but Next, and deselect Create module-info.java file

In order to read a csv in that doesn't have a header and for only certain columns you need to pass params header=None and usecols=[3,6] for the 4th and 7th columns:

df = pd.read_csv(file_path, header=None, usecols=[3,6])

See the docs

Looks like your problem is that you are trying to run python test.py from within the Python interpreter, which is why you're seeing that traceback.

Make sure you're out of the interpreter, then run the python test.py command from bash or command prompt or whatever.

Still better solution could be to follow a design pattern such that the back-button press event gets propagated from active fragment down to host Activity. So, it's like.. if one of the active fragments consume the back-press, the Activity wouldn't get to act upon it, and vice-versa.

One way to do it is to have all your Fragments extend a base fragment that has an abstract 'boolean onBackPressed()' method.

@Override
public boolean onBackPressed() {
   if(some_condition)
      // Do something
      return true; //Back press consumed.
   } else {
      // Back-press not consumed. Let Activity handle it
      return false;
   }
}

Keep track of active fragment inside your Activity and inside it's onBackPressed callback write something like this

@Override
public void onBackPressed() {
   if(!activeFragment.onBackPressed())
      super.onBackPressed();
   }
}

This post has this pattern described in detail

use Contains of jquery Contains like this

if ($('.type:contains("> <")').length > 0)
{
 //do stuffs to change 
}

This helped in my case :

1. close VS instance
2. open Control Panel\User Accounts\Credential Manager
3. Remove TFS related credentials from vault

This is just a hack. You need to do it regulary ... :-(

Update: I have found a better/proper way to solve this problem using a BehaviorSubject or an Observable rather than an EventEmitter. Please see this answer: https://stackoverflow.com/a/35568924/215945

Also, the Angular docs now have a cookbook example that uses a Subject.

Original/outdated/wrong answer: again, don't use an EventEmitter in a service. That is an anti-pattern.

Using beta.1... NavService contains the EventEmiter. Component Navigation emits events via the service, and component ObservingComponent subscribes to the events.

nav.service.ts

import {EventEmitter} from 'angular2/core';
export class NavService {
  navchange: EventEmitter<number> = new EventEmitter();
  constructor() {}
  emitNavChangeEvent(number) {
    this.navchange.emit(number);
  }
  getNavChangeEmitter() {
    return this.navchange;
  }
}

components.ts

import {Component} from 'angular2/core';
import {NavService} from '../services/NavService';

@Component({
  selector: 'obs-comp',
  template: `obs component, item: {{item}}`
})
export class ObservingComponent {
  item: number = 0;
  subscription: any;
  constructor(private navService:NavService) {}
  ngOnInit() {
    this.subscription = this.navService.getNavChangeEmitter()
      .subscribe(item => this.selectedNavItem(item));
  }
  selectedNavItem(item: number) {
    this.item = item;
  }
  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

@Component({
  selector: 'my-nav',
  template:`
    <div class="nav-item" (click)="selectedNavItem(1)">nav 1 (click me)</div>
    <div class="nav-item" (click)="selectedNavItem(2)">nav 2 (click me)</div>
  `,
})
export class Navigation {
  item = 1;
  constructor(private navService:NavService) {}
  selectedNavItem(item: number) {
    console.log('selected nav item ' + item);
    this.navService.emitNavChangeEvent(item);
  }
}

Plunker

Dont forget to add user agent since some server will block request if there's no server agent..(you would get Forbidden resource response) example :

curl -X POST -A 'Mozilla/5.0 (X11; Linux x86_64; rv:30.0) Gecko/20100101 Firefox/30.0' -d "field=acaca&name=afadxx" https://example.com

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

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

to this:

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

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

instead of using time try timedelta:

from datetime import timedelta

t1 = timedelta(hours=7, minutes=36)
t2 = timedelta(hours=11, minutes=32)
t3 = timedelta(hours=13, minutes=7)
t4 = timedelta(hours=21, minutes=0)

arrival = t2 - t1
lunch = (t3 - t2 - timedelta(hours=1))
departure = t4 - t3

print(arrival, lunch, departure)

Try CAST(CAST(@value AS bigint) AS varchar)

The appropriate regex would be the ' char followed by any number of any chars [including zero chars] ending with an end of string/line token:

'.*$

And if you wanted to capture everything after the ' char but not include it in the output, you would use:

(?<=').*$

This basically says give me all characters that follow the ' char until the end of the line.

Edit: It has been noted that $ is implicit when using .* and therefore not strictly required, therefore the pattern:

'.* 

is technically correct, however it is clearer to be specific and avoid confusion for later code maintenance, hence my use of the $. It is my belief that it is always better to declare explicit behaviour than rely on implicit behaviour in situations where clarity could be questioned.

I don't know if this will help, but here's the SWT FAQ question How do I use Mozilla as the Browser's underlying renderer?

Edit: Having researched this further, it sounds like this isn't possible in Eclipse 3.4, but may be slated for a later release.

1. Download the source code(zip or rar package).
2. Run the setup.py inside.

So use a semi-colon:

alias lock='gnome-screensaver; gnome-screen-saver-command --lock'

This doesn't work well if you want to supply arguments to the first command. Alternatively, create a trivial script in your $HOME/bin directory.

If you want to update data you should use UPDATE command instead of INSERT

Use this below code

 border:2px soild #eee;

 margin: 15px 15px;
 -webkit-box-shadow: 2px 3px 8px #eee;
-moz-box-shadow: 2px 3px 8px #eee;
box-shadow: 2px 3px 8px #eee;

Explanation:-

box-shadow requires you to set the horizontal & vertical offsets, you can then optionally set the blur and colour, you can also choose to have the shadow inset instead of the default outset. Colour can be defined as hex or rgba.

box-shadow : inset/outset h-offset v-offset blur spread color;

Explanation of the values...

inset/outset -- whether the shadow is inside or outside the box. If not specified it will default to outset.

h-offset -- the horizontal offset of the shadow (required value)

v-offset -- the vertical offset of the shadow (required value)

blur -- as it says, the blur of the shadow

spread -- moves the shadow away from the box equally on all sides. A positive value causes the shadow to expand, negative causes it to contract. Though this value isn't often used, it is useful with multiple shadows.

color -- as it says, the color of the shadow

Usage

box-shadow:2px 3px 8px #eee; a gray shadow with a horizontal outset of 2px, vertical of 3px and a blur of 8px

In general, there isn't a way to determine which particular statement caused the error. If you're running several, you could watch profiler and look at the last completed statement and see what the statement after that might be, though I have no idea if that approach is feasible for you.

In any event, one of your parameter variables (and the data inside it) is too large for the field it's trying to store data in. Check your parameter sizes against column sizes and the field(s) in question should be evident pretty quickly.

This above does not work because sometimes

$(this).attr('checked') == undefined

adjust your code with

if(!$(this).attr('checked') || $(this).attr('checked') == false){

If you need the list of users that are in a group, you can do this instead:

from django.contrib.auth.models import Group
users_in_group = Group.objects.get(name="group name").user_set.all()

and then check

 if user in users_in_group:
     # do something

to check if the user is in the group.

Just put a '!' in front of the boolean expression

This is Web GUI of a GitHub repository:

Drag and drop your folder to the above area. When you upload too much folder/files, GitHub will notice you:

Yowza, that’s a lot of files. Try again with fewer than 100 files.

and add commit message

And press button Commit changes is the last step.

If you want fix the column you should set width. For example:

<td style="width:100px;">some data</td>

If you want to do multiple $ne then do

db.users.find({name : {$nin : ["mary", "dick", "jane"]}})

In my mind I have to consider that the foo folder is a stand-alone library. I might want to consider moving it to the Lib\site-packages folder within a python installation. I might want to consider adding a foo.pth file there.

I know it's a library since the ./programs/my_python_program.py contains the following line:

from foo.tasks import my_function

So it doesn't matter that ./programs is a sibling folder to ./foo. It's the fact that my_python_program.py is run as a script like this:

python ./programs/my_python_program.py

This should work as well.

#include <ctype.h>
#include <string.h>

template<typename T = unsigned int>
T Hex2Int(const char* const Hexstr, bool* Overflow)
{
    if (!Hexstr)
        return false;
    if (Overflow)
        *Overflow = false;

    auto between = [](char val, char c1, char c2) { return val >= c1 && val <= c2; };
    size_t len = strlen(Hexstr);
    T result = 0;

    for (size_t i = 0, offset = sizeof(T) << 3; i < len && (int)offset > 0; i++)
    {
        if (between(Hexstr[i], '0', '9'))
            result = result << 4 ^ Hexstr[i] - '0';
        else if (between(tolower(Hexstr[i]), 'a', 'f'))
            result = result << 4 ^ tolower(Hexstr[i]) - ('a' - 10); // Remove the decimal part;
        offset -= 4;
    }
    if (((len + ((len % 2) != 0)) << 2) > (sizeof(T) << 3) && Overflow)
        *Overflow = true;
    return result;
}

The 'Overflow' parameter is optional, so you can leave it NULL.

Example:

auto result = Hex2Int("C0ffee", NULL);
auto result2 = Hex2Int<long>("DeadC0ffe", NULL);

Yes, you can do this by creating a DoubleStream from the array, filtering out the negatives, and converting the stream back to an array. Here is an example:

double[] d = {8, 7, -6, 5, -4};
d = Arrays.stream(d).filter(x -> x > 0).toArray();
//d => [8, 7, 5]

If you want to filter a reference array that is not an Object[] you will need to use the toArray method which takes an IntFunction to get an array of the original type as the result:

String[] a = { "s", "", "1", "", "" };
a = Arrays.stream(a).filter(s -> !s.isEmpty()).toArray(String[]::new);

Your css is almost correct. You are just missing display: block; in image css. Also one typo in your id. It should be <div id="ImageContainer">

img.Image { max-width: 100%; display: block; }_x000D_
div#ImageContainer { width: 600px; }

<div id="ImageContainer">_x000D_
    <img src="http://placehold.it/1000x600" class="Image">_x000D_
</div>

Use

<% String username = (String)request.getSession().getAttribute(...); %>

Note that your use of <%! ... %> is translated to class-level, but request is only available in the service() method of the translated servlet.

See how JSP code is translated to a servlet.

I would have to say SimpleXML takes the cake because it is firstly an extension, written in C, and is very fast. But second, the parsed document takes the form of a PHP object. So you can "query" like $root->myElement.

Here is an example of passing mode as optional parameter

void myfunc(int blah, int mode = 0)
{
    if (mode == 0)
        do_something();
     else
        do_something_else();
}

you can call myfunc in both ways and both are valid

myfunc(10);     // Mode will be set to default 0
myfunc(10, 1);  // Mode will be set to 1

You have asked two questions, one in the title about the difference between PNG8 and PNG24, which has received a few answers, namely that PNG24 has 8-bit red, green, and blue channels, and PNG-8 has a single 8-bit index into a palette. Naturally, PNG24 usually has a larger filesize than PNG8. Furthermore, PNG8 usually means that it is opaque or has only binary transparency (like GIF); it's defined that way in ImageMagick/GraphicsMagick.

This is an answer to the other one, "I would like to know that if I use either type in my html page, will there be any error? Or is this only quality matter?"

You can put either type on an HTML page and no, this won't cause an error; the files should all be named with the ".png" extension and referred to that way in your HTML. Years ago, early versions of Internet Explorer would not handle PNG with an alpha channel (PNG32) or indexed-color PNG with translucent pixels properly, so it was useful to convert such images to PNG8 (indexed-color with binary transparency conveyed via a PNG tRNS chunk) -- but still use the .png extension, to be sure they would display properly on IE. I think PNG24 was always OK on Internet Explorer because PNG24 is either opaque or has GIF-like single-color transparency conveyed via a PNG tRNS chunk.

The names PNG8 and PNG24 aren't mentioned in the PNG specification, which simply calls them all "PNG". Other names, invented by others, include

• PNG8 or PNG-8 (indexed-color with 8-bit samples, usually means opaque or with GIF-like, binary transparency, but sometimes includes translucency)
• PNG24 or PNG-24 (RGB with 8-bit samples, may have GIF-like transparency via tRNS)
• PNG32 (RGBA with 8-bit samples, opaque, transparent, or translucent)
• PNG48 (Like PNG24 but with 16-bit R,G,B samples)
• PNG64 (like PNG32 but with 16-bit R,G,B,A samples)

There are many more possible combinations including grayscale with 1, 2, 4, 8, or 16-bit samples and indexed PNG with 1, 2, or 4-bit samples (and any of those with transparent or translucent pixels), but those don't have special names.

To quote the help page (try ?integer), bolded portion mine:

Integer vectors exist so that data can be passed to C or Fortran code which expects them, and so that (small) integer data can be represented exactly and compactly.

Note that current implementations of R use 32-bit integers for integer vectors, so the range of representable integers is restricted to about +/-2*10^9: doubles can hold much larger integers exactly.

Like the help page says, R's integers are signed 32-bit numbers so can hold between -2147483648 and +2147483647 and take up 4 bytes.

R's numeric is identical to an 64-bit double conforming to the IEEE 754 standard. R has no single precision data type. (source: help pages of numeric and double). A double can store all integers between -2^53 and 2^53 exactly without losing precision.

We can see the data type sizes, including the overhead of a vector (source):

> object.size(1:1000)
4040 bytes
> object.size(as.numeric(1:1000))
8040 bytes

Have you tried simply opening them in OpenOffice.org?

I had a similar problem some time ago and found that Excel and Calc didn't understand each other's encryption, and so allowed direct access to just about everything.

This was a while ago, so if that wasn't just a fluke on my part it also may have been patched.

If using jQuery 1.7+:

You can call off before on:

$('#myButton').off('click', onButtonClicked) // remove handler
              .on('click', onButtonClicked); // add handler

If not:

You can just unbind it first event:

$('#myButton').unbind('click', onButtonClicked) //remove handler
              .bind('click', onButtonClicked);  //add handler

For people having a startTime (like 12h:30:30) and a duration (value in minutes like 120), you can guess the endTime like so:

const startTime = '12:30:00';
const durationInMinutes = '120';

const endTime = moment(startTime, 'HH:mm:ss').add(durationInMinutes, 'minutes').format('HH:mm');

// endTime is equal to "14:30"

Not currently. If you look at the source code (from this point in time Oct 2012), you'll see that the call to XHR open is actually hard-coded to be asynchronous (the third parameter is true):

 xhr.open(method, url, true);

You'd need to write your own service that did synchronous calls. Generally that's not something you'll usually want to do because of the nature of JavaScript execution you'll end up blocking everything else.

... but.. if blocking everything else is actually desired, maybe you should look into promises and the $q service. It allows you to wait until a set of asynchronous actions are done, and then execute something once they're all complete. I don't know what your use case is, but that might be worth a look.

Outside of that, if you're going to roll your own, more information about how to make synchronous and asynchronous ajax calls can be found here.

I hope that is helpful.

Glimmer is an interesting option for JRuby users which provides a very Ruby-ish interface to the SWT toolkit. (SWT is the user interface framework behind Eclipse, which delivers fast performance and familiar UI metaphors by making use of native widgets on the various platforms it supports: Windows, OS X, Linux, etc.) SWT always appealed to me as a Java developer, but coding it was painful in the extreme. Glimmer makes the process a lot more straightforward by emphasizing convention over configuration, and by valuing DRYness and all the other normal Ruby goodness.

Another neat option is SproutCore, a Javascript-based GUI toolkit with Ruby bindings developed by Apple. At least, the demos for it look great, and otherinbox built a pretty slick looking application on top of it. Personally, I've spent quite a few hours trying to get it running on two systems -- one Windows and one Linux -- and haven't succeeded on either one -- I keep running into dependency issues with Merb or other pieces of the SproutCore stack. But it's intriguing enough that I'll go back after a few weeks and try again, hoping that the issues get resolved in that time.

Edit (2020.12.28): GitHub change default master branch to main branch since October 2020. See https://github.com/github/renaming

Update March 2013

Git 1.8.2 added the possibility to track branches.

"git submodule" started learning a new mode to integrate with the tip of the remote branch (as opposed to integrating with the commit recorded in the superproject's gitlink).

# add submodule to track master branch
git submodule add -b master [URL to Git repo];

# update your submodule
git submodule update --remote 

If you had a submodule already present you now wish would track a branch, see "how to make an existing submodule track a branch".

Also see Vogella's tutorial on submodules for general information on submodules.

Note:

git submodule add -b . [URL to Git repo];
                    ^^^

See git submodule man page:

A special value of . is used to indicate that the name of the branch in the submodule should be the same name as the current branch in the current repository.

See commit b928922727d6691a3bdc28160f93f25712c565f6:

submodule add: If --branch is given, record it in .gitmodules

This allows you to easily record a submodule.<name>.branch option in .gitmodules when you add a new submodule. With this patch,

$ git submodule add -b <branch> <repository> [<path>]
$ git config -f .gitmodules submodule.<path>.branch <branch>

reduces to

$ git submodule add -b <branch> <repository> [<path>]

This means that future calls to

$ git submodule update --remote ...

will get updates from the same branch that you used to initialize the submodule, which is usually what you want.

Original answer (February 2012):

A submodule is a single commit referenced by a parent repo.
Since it is a Git repo on its own, the "history of all commits" is accessible through a git log within that submodule.

So for a parent to track automatically the latest commit of a given branch of a submodule, it would need to:

• cd in the submodule
• git fetch/pull to make sure it has the latest commits on the right branch
• cd back in the parent repo
• add and commit in order to record the new commit of the submodule.

gitslave (that you already looked at) seems to be the best fit, including for the commit operation.

It is a little annoying to make changes to the submodule due to the requirement to check out onto the correct submodule branch, make the change, commit, and then go into the superproject and commit the commit (or at least record the new location of the submodule).

Other alternatives are detailed here.

"Timeline (responsive)" snippet:

This looks very, very close to what your example shows. The bootstrap snippet linked below covers all the bases you are looking for. I've been considering it myself, with the same requirements you have ( especially responsiveness ). This morphs well between screen sizes and devices.

You can fork this and use it as a great starting point for your specific expectations:

• http://bootsnipp.com/snippets/featured/timeline-responsive

Here are two screenshots I took for you... wide and thin:

Your assumptions don't seem to be right. After a clear(), the newly added data start from index 0.

https://github.com/keithrowell/rails_default_value

class Task < ActiveRecord::Base
  default :status => 'active'
end

You can create a Global Class like this:

public class GlobalClass extends Application{

    private String name;
    private String email;

    public String getName() {
        return name;
    }

    public void setName(String aName) {
        name = aName;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String aEmail) {
        email = aEmail;
    }
}

Then define it in the manifest:

<application
    android:name="com.example.globalvariable.GlobalClass" ....

Now you can set values to global variable like this:

final GlobalClass globalVariable = (GlobalClass) getApplicationContext();
globalVariable.setName("Android Example context variable");

You can get those values like this:

final GlobalClass globalVariable = (GlobalClass) getApplicationContext();
final String name  = globalVariable.getName();

Please find complete example from this blog Global Variables

1. git checkout [branchYouWantToReceiveBranch] - checkout branch you want to receive branch
2. git merge [branchYouWantToMergeIntoBranch]

I solved this issue by doing like that:

insert into my_table(my_field_0, ..., my_field_n) values(my_value_0, ..., my_value_n)

If you can use the terrific moment library (e.g. in an Node.js project) you can easily parse your date using e.g.

var momentDate = moment("2014-09-15 09:00:00");

and can access the JS date object via

momentDate ().toDate();

Since the question was first asked, there has been a change to that answer from a flat out "no" to a "kind of"

http://github.com/facebook/hiphop-php/wiki

Hip Hop for PHP was a compiler that took PHP code and turned it into highly optimized C++ Apparently, some functions are not supported (for example 'explode')

I found this question while looking for more information on how to implement HipHop and thought I'd speak up :)

Since 2013 Facebook no longer use it, however, and it has been discontinued in favour of HHVM, which is not a compiler: https://en.wikipedia.org/wiki/HipHop_for_PHP

I found this method working quite well (for me) to produce a flat array of unique values:

$uniqueNames = User::select('name')->distinct()->pluck('name')->toArray();

If you ran ->toSql() on this query builder, you will see it generates a query like this:

select distinct `name` from `users`

The ->pluck() is handled by illuminate\collection lib (not via sql query).

We had the same issue with our Azure DevOps repositories after our domain changed, i.e. from @xy.com to @xyz.com. To fix this issue, we generated a fresh personal access token with the following permissions:

Code: read & write Packaging: read

Then we opened the Windows Credential Manager, added a new generic windows credential with the following details:

Internet or network address: "git:{projectname}@dev.azure.com/{projectname}" - alternatively you should use your git repository name here.
User name: "Personal Access Token"
Password: {The generated Personal Access Token}

Afterwards all our git operations were working again. Hope this helps someone else!

If it's running all of the above from the command line that you're looking for, then I'd recommend HTTPie. It is a fantastic cURL alternative and is super easy and convenient to use (and customize).

Here's is its (succinct and precise) description from GitHub;

HTTPie (pronounced aych-tee-tee-pie) is a command line HTTP client. Its goal is to make CLI interaction with web services as human-friendly as possible.

It provides a simple http command that allows for sending arbitrary HTTP requests using a simple and natural syntax, and displays colorized output. HTTPie can be used for testing, debugging, and generally interacting with HTTP servers.

The documentation around authentication should give you enough pointers to solve your problem(s). Of course, all of the answers above are accurate as well, and provide different ways of accomplishing the same task.

Just so you do NOT have to move away from Stack Overflow, here's what it offers in a nutshell.

Basic auth:_x000D_
_x000D_
$ http -a username:password example.org_x000D_
Digest auth:_x000D_
_x000D_
$ http --auth-type=digest -a username:password example.org_x000D_
With password prompt:_x000D_
_x000D_
$ http -a username example.org

Because the numbers after point is only zero, the best solution is to use the Math.Round(MyNumber)

When you're in a detached head situation and created new files, first make sure that these new files are added to the index, for example with:

git add .

But if you've only changed or deleted existing files, you can add (-a) and commit with a message (-m) at the the same time via:

git commit -a -m "my adjustment message"

Then you can simply create a new branch with your current state with:

git checkout -b new_branch_name

You'll have a new branch and all your adjustments will be there in that new branch. You can then continue to push to the remote and/or checkout/pull/merge as you please.

I had same issue on 27 Sep 2019.

My API is in Dot net core Targeting to .net framework. edmx is in a different class library which is in .net framework only.

I observed that when I try to call that edmx from API .. for some reason I got that error.

What I did is, go to the obj folder of API and delete everything. then clean the API project and try again and that worked for me.
