Say you want to answer a request with a 204: No Content HTTP status. Firefox will complain with "no element found" in the console of the browser. This is a bug in Firefox that has been reported, but never fixed, for several years. By sending a "Content-type: text/plain" header, you can prevent this error in Firefox.

There is a much easier way to compile and run C code using GCC, no configuration needed:

1. Install the Code Runner Extension
2. Open your C code file in Text Editor, then use shortcut Ctrl+Alt+N, or press F1 and then select/type Run Code, or right click the Text Editor and then click Run Code in context menu, the code will be compiled and run, and the output will be shown in the Output Window.

Moreover you could update the config in settings.json using different C compilers as you want, the default config for C is as below:

"code-runner.executorMap": {
    "c": "gcc $fullFileName && ./a.out"
}

Sass cannot perform arithmetic on values that cannot be converted from one unit to the next. Sass has no way of knowing exactly how wide "100%" is in terms of pixels or any other unit. That's something only the browser knows.

You need to use calc() instead. Check browser compatibility on Can I use...

.foo {
    height: calc(25% - 5px);
}

If your values are in variables, you may need to use interpolation turn them into strings (otherwise Sass just tries to perform arithmetic):

$a: 25%;
$b: 5px;

.foo {
  width: calc(#{$a} - #{$b});
}

You can do like this also:

HTML:

<a><img src='https://encrypted-tbn2.google.com/images?q=tbn:ANd9GcQB3a3aouZcIPEF0di4r9uK4c0r9FlFnCasg_P8ISk8tZytippZRQ' onmouseover="somefunction();"></a>

In javascript:

function somefunction()
{
  //Do somethisg.
}

?

the solution is easy: execute via sh

... -exec sh -c "zcat {} | agrep -dEOE 'grep' " \;

For your first method change ws.Range("A") to ws.Range("A:A") which will search the entirety of column a, like so:

Sub Find_Bingo()

        Dim wb As Workbook
        Dim ws As Worksheet
        Dim FoundCell As Range
        Set wb = ActiveWorkbook
        Set ws = ActiveSheet

            Const WHAT_TO_FIND As String = "Bingo"

            Set FoundCell = ws.Range("A:A").Find(What:=WHAT_TO_FIND)
            If Not FoundCell Is Nothing Then
                MsgBox (WHAT_TO_FIND & " found in row: " & FoundCell.Row)
            Else
                MsgBox (WHAT_TO_FIND & " not found")
            End If
End Sub

For your second method, you are using Bingo as a variable instead of a string literal. This is a good example of why I add Option Explicit to the top of all of my code modules, as when you try to run the code it will direct you to this "variable" which is undefined and not intended to be a variable at all.

Additionally, when you are using With...End With you need a period . before you reference Cells, so Cells should be .Cells. This mimics the normal qualifying behavior (i.e. Sheet1.Cells.Find..)

Change Bingo to "Bingo" and change Cells to .Cells

With Sheet1
        Set FoundCell = .Cells.Find(What:="Bingo", After:=.Cells(1, 1), _
        LookIn:=xlValues, lookat:=xlPart, SearchOrder:=xlByRows, _
        SearchDirection:=xlNext, MatchCase:=False, SearchFormat:=False)
    End With

If Not FoundCell Is Nothing Then
        MsgBox ("""Bingo"" found in row " & FoundCell.Row)
Else
        MsgBox ("Bingo not found")
End If

Update

In my

With Sheet1
    .....
End With

The Sheet1 refers to a worksheet's code name, not the name of the worksheet itself. For example, say I open a new blank Excel workbook. The default worksheet is just Sheet1. I can refer to that in code either with the code name of Sheet1 or I can refer to it with the index of Sheets("Sheet1"). The advantage to using a codename is that it does not change if you change the name of the worksheet.

Continuing this example, let's say I renamed Sheet1 to Data. Using Sheet1 would continue to work, as the code name doesn't change, but now using Sheets("Sheet1") would return an error and that syntax must be updated to the new name of the sheet, so it would need to be Sheets("Data").

In the VB Editor you would see something like this:

Notice how, even though I changed the name to Data, there is still a Sheet1 to the left. That is what I mean by codename.

The Data worksheet can be referenced in two ways:

Debug.Print Sheet1.Name
Debug.Print Sheets("Data").Name

Both should return Data

More discussion on worksheet code names can be found here.

            }
        }
    });
</script>

You can check the long-running queries details like % completed and remaining time using the below query:

 SELECT SID, SERIAL#, OPNAME, CONTEXT, SOFAR, 
 TOTALWORK,ROUND(SOFAR/TOTALWORK*100,2) "%_COMPLETE" 
 FROM V$SESSION_LONGOPS 
 WHERE OPNAME NOT LIKE '%aggregate%' 
       AND TOTALWORK != 0 
       AND SOFAR <> TOTALWORK;

Bundling Steps

• npm run bundle (run in cmd when direcory is projectFolder)

  bundles are generated to projectFolder / bundles /

Output

• bundles/dependencies.bundle.js [ size: ~ 1 MB (as small as possible) ]

The best I could do yet :)

Try the below code -

playButton.setVisibility(View.INVISIBLE);

or -

playButton.setVisibility(View.GONE);

show it again with -

playButton.setVisibility(View.VISIBLE);

a very simple, one-line solution, is to add line-heigth to the div, having in mind that all the div's text will go bottom.

CSS:

#layer{width:198px;
       height:48px;
       line-height:72px;
       border:1px #000 solid}
#layer a{text-decoration:none;}

HTML:

<div id="layer">
    <a href="#">text at div's bottom.</a>
</div>

keep in mind that this is a practical and fast solution when you just want text inside div to go down, if you need to combine images and stuff, you will have to code a bit more complex and responsive CSS

When using the .html() method, a htmlString must be the parameter. (source) Put your string inside a HTML tag and it should work or use .text() as suggested by farzad.

Example:

<div class="demo-container">
    <div class="demo-box">Demonstration Box</div>
</div>

<script type="text/javascript">
$("div.demo-container").html( "<p>All new content. <em>You bet!</em></p>" );
</script>

You typically do commit .gitignore. In fact, I personally go as far as making sure my index is always clean when I'm not working on something. (git status should show nothing.)

There are cases where you want to ignore stuff that really isn't project specific. For example, your text editor may create automatic *~ backup files, or another example would be the .DS_Store files created by OS X.

I'd say, if others are complaining about those rules cluttering up your .gitignore, leave them out and instead put them in a global excludes file.

By default this file resides in $XDG_CONFIG_HOME/git/ignore (defaults to ~/.config/git/ignore), but this location can be changed by setting the core.excludesfile option. For example:

git config --global core.excludesfile ~/.gitignore

Simply create and edit the global excludesfile to your heart's content; it'll apply to every git repository you work on on that machine.

While I agree with Jon Skeet in principle, sometimes I don't have the option to use an external XML library. And I find it peculiar the two functions to escape/unescape a simple value (attribute or tag, not full document) are not available in the standard XML libraries included with Java.

As a result and based on the different answers I have seen posted here and elsewhere, here is the solution I've ended up creating (nothing worked as a simple copy/paste):

  public final static String ESCAPE_CHARS = "<>&\"\'";
  public final static List<String> ESCAPE_STRINGS = Collections.unmodifiableList(Arrays.asList(new String[] {
      "&lt;"
    , "&gt;"
    , "&amp;"
    , "&quot;"
    , "&apos;"
  }));

  private static String UNICODE_NULL = "" + ((char)0x00); //null
  private static String UNICODE_LOW =  "" + ((char)0x20); //space
  private static String UNICODE_HIGH = "" + ((char)0x7f);

  //should only be used for the content of an attribute or tag      
  public static String toEscaped(String content) {
    String result = content;
    
    if ((content != null) && (content.length() > 0)) {
      boolean modified = false;
      StringBuilder stringBuilder = new StringBuilder(content.length());
      for (int i = 0, count = content.length(); i < count; ++i) {
        String character = content.substring(i, i + 1);
        int pos = ESCAPE_CHARS.indexOf(character);
        if (pos > -1) {
          stringBuilder.append(ESCAPE_STRINGS.get(pos));
          modified = true;
        }
        else {
          if (    (character.compareTo(UNICODE_LOW) > -1)
               && (character.compareTo(UNICODE_HIGH) < 1)
             ) {
            stringBuilder.append(character);
          }
          else {
            //Per URL reference below, Unicode null character is always restricted from XML
            //URL: https://en.wikipedia.org/wiki/Valid_characters_in_XML
            if (character.compareTo(UNICODE_NULL) != 0) {
              stringBuilder.append("&#" + ((int)character.charAt(0)) + ";");
            }
            modified = true;
          }
        }
      }
      if (modified) {
        result = stringBuilder.toString();
      }
    }
    
    return result;
  }

The above accommodates several different things:

1. avoids using char based logic until it absolutely has to - improves unicode compatibility
2. attempts to be as efficient as possible given the probability is the second "if" condition is likely the most used pathway
3. is a pure function; i.e. is thread-safe
4. optimizes nicely with the garbage collector by only returning the contents of the StringBuilder if something actually changed - otherwise, the original string is returned

At some point, I will write the inversion of this function, toUnescaped(). I just don't have time to do that today. When I do, I will come update this answer with the code. :)

Layout:

        {

As an alternative way you can use DriverManagerDataSource such as:

public DataSource getDataSource(DBInfo db) {

    DriverManagerDataSource dataSource = new DriverManagerDataSource();

    dataSource.setUsername(db.getUsername());
    dataSource.setPassword(db.getPassword());
    dataSource.setUrl(db.getUrl());
    dataSource.setDriverClassName(db.getDriverClassName());

    return dataSource;
}

However be careful about using it, because:

NOTE: This class is not an actual connection pool; it does not actually pool Connections. It just serves as simple replacement for a full-blown connection pool, implementing the same standard interface, but creating new Connections on every call. reference

There is a much easier way to run Java, no configuration needed:

1. Install the Code Runner Extension
2. Open your Java code file in Text Editor, then use shortcut Ctrl+Alt+N, or press F1 and then select/type Run Code, or right click the Text Editor and then click Run Code in context menu, the code will be compiled and run, and the output will be shown in the Output Window.

color:transparent; and then any text-transform property does the trick too.

For example:

color: transparent;
text-transform: uppercase;

I'm having a hard time figuring out what exactly you're looking for here, so hope I'm not way off base.

I'm assuming what you mean is that when a keyup event occurs on the input with class "start" you want to get the values of all the inputs in neighbouring <td>s:

    $('.start').keyup(function() {
        var otherInputs = $(this).parents('td').siblings().find('input');

        for(var i = 0; i < otherInputs.length; i++) {
            alert($(otherInputs[i]).val());
        }
        return false;
    });

use loop

  for (int i = 0; i < dt1.Rows.Count; i++)
        {      
           dt2.Rows.Add(dt1.Rows[i][0], dt1.Rows[i][1], ...);//you have to insert all Columns...
        }

Only related with currency trading (Forex), but many Forex brokers are offering MetaTrader which let you code in MQL. The main problem with it (aside that it's limited to Forex) is that you've to code in MQL which might not be your preferred language.

I came across the same problem recently. I’m becoming more partial to the “always use a virtualenv” mindset, so my problem was to install virtualenv with pip without installing distribute to my global or user site-packages directory. To do this, I manually downloaded distribute, pip and virtualenv, and for each one I ran “python setup.py install --prefix ~/.local/python-private” (with a temporary setting of PYTHONPATH=~/.local/python-private) so that setup scripts were able to find distribute). I’ve moved the virtualenv script to another directory I have on my PATH and edited it so that the distribute and virtualenv modules can be found on sys.path. Tada: I did not install anything to /usr, /usr/local or my user site-packages dir, but I can run virtualenv anywhere, and in that virtualenv I get pip.

For win7 chrome can be found at:

C:\Users\[UserName]\AppData\Local\Google\Chrome\Application\chrome.exe

For VS2017 click the little down arrow next to the run in debug/release mode button to find the "browse with..." option.

There's nothing wrong with include file in head. It seems you forgot to add;. Please try this one:

<body onload="imageRefreshBig();">

But as per my knowledge semicolons are optional. You can try with ; but better debug code and see if chrome console gives any error.

I hope this helps.

For ignoring subfolders but not main folder I could only get this to work in Visual Studio Code by placing a dummy readme.txt in the main folder. Only then /*/ checked in the main folder (and no subfolders).

This problem was solved for me by running VMware workstation as Windows administrator. From the start menu right click on the VMware workstation, then select "Run as Administrator"

The solution to this question is very easy: Vectors

std::vector<int> vector;
for(int i = 0; i < 10;i++)
{
    vector.push_back(i);
}
std::reverse(vector.begin(), vector.end());

Voila! You are done! =)

Solution details:

This is the most efficent solution: Swap can't swap 3 values but reverse definitely can. Remember to include algorithm. This is so simple that the compiled code is definitely not needed.

I think this solves the OP's problem

If you think there are any errors and problems with this solution please comment below

You could try this method:

List<string> temp = new List<string>();

    foreach (string item in listBox1.Items)
    {
        string removelistitem = "OBJECT";
        if(item.Contains(removelistitem))
        {
            temp.Items.Add(item);
         }
     }

    foreach(string item in temp)
    {
       listBox1.Items.Remove(item);
    }

This should be correct as it simply copies the contents to a temporary list which is then used to delete it from the ListBox.

Everyone else please feel free to mention corrections as i'm not 100% sure it's completely correct, i used it a long time ago.

The accepted answer from Thorn007 doesn't work when the image is too small.

To solve this, I added a scale factor. This way, it makes the image bigger and it fills the div container.

Example:

<div style="width:400px; height:200px;">
  <img src="pix.jpg" style="max-width:100px; height:50px; transform:scale(4); transform-origin:left top;" />
</div>

Notes:

1. For WebKit you must add -webkit-transform:scale(4); -webkit-transform-origin:left top; in the style.
2. With a scale factor of 4, you have max-width = 400/4 = 100 and max-height = 200/4 = 50
3. An alternate solution is to set max-width and max-height at 25%. It's even simpler.

I tried several methods but didn't work. The only one that did is the one right at the bottom. I'll just list the other options I tried as well, for reference.

Some background, I migrated from Mars to Neon and copied over eclipse.ini almost exactly.

Reduce -XX:MaxPermSize and -Xmx

Like other answers have mentioned, progressively reduce these 2 flags (eg to 128m) and try again. If it still doesn't work at 128m then try other options below.

Find the offending flag by renaming eclipse.ini

Jon H's answer gave me a hint. Delete eclipse.ini (or rename it) and start eclipse. It should regen eclipse.ini and launch successfully (mine didn't regen eclipse.ini though eclipse launched fine).

If eclipse.ini did regen for you, then add each flag back one-by-one.

If not, revert the original eclipse.ini and remove each flag one-by-one until you've found the flag that causes an error.

For my case, I upgraded from Mars to Neon. The offending flag was -XX:+UseG1GC Removing this flag (and only this flag) worked for me. Setting back -Xmx and -XX:MaxPermSize to 1G worked for me as well.

Slightly off topic, but have you considered Windows Scripting Host? You might find it nicer.

sara is the struct itself, not a pointer (i.e. the variable representing location on the stack where actual struct data is stored). Therefore, *sara is meaningless and won't compile.

BigDecimal test = new BigDecimal(0);
System.out.println(test);
test = test.add(new BigDecimal(30));
System.out.println(test);
test = test.add(new BigDecimal(45));
System.out.println(test);

The operations needed to be performed, require numpy arrays either created via

np.array()

or can be converted from list to an array via

np.stack()

As in the above mentioned case, 2 lists are inputted as operands it triggers the error.

String path = "C:\\Documents and Settings\\Manoj\\Desktop";
path = path.replace("\\", "/");
// or
path = path.replaceAll("\\\\", "/");

You may try Easy Python Decompiler. It's based on Decompyle++ and Uncompyle2. It's supports decompiling python versions 1.0-3.3

Note: I am the author of the above tool.

The code below demonstrates on how to do this.

var http = new XMLHttpRequest();
var url = 'get_data.php';
var params = 'orem=ipsum&name=binny';
http.open('POST', url, true);

//Send the proper header information along with the request
http.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');

http.onreadystatechange = function() {//Call a function when the state changes.
    if(http.readyState == 4 && http.status == 200) {
        alert(http.responseText);
    }
}
http.send(params);

In case you have/create an object you can turn it into params using the following code, i.e:

var params = new Object();
params.myparam1 = myval1;
params.myparam2 = myval2;

// Turn the data object into an array of URL-encoded key/value pairs.
let urlEncodedData = "", urlEncodedDataPairs = [], name;
for( name in params ) {
 urlEncodedDataPairs.push(encodeURIComponent(name)+'='+encodeURIComponent(params[name]));
}

Set focus: The framework will handled moving focus in response to user input. To force focus to a specific view, call requestFocus()

I think that the solution of @Azimuts (https://stackoverflow.com/a/33375677/6503697) is for HTTP only connection. For FTPS connection you can use Bouncy Castle with org.apache.commons.net.ftp.FTPSClient without the need for rewrite FTPS protocol.

I have a program running on JRE 1.6.0_04 and I can not update the JRE.

The program has to connect to an FTPS server that work only with TLS 1.2 (IIS server).

I struggled for days and finally I have understood that there are few versions of bouncy castle library right in my use case: bctls-jdk15on-1.60.jar and bcprov-jdk15on-1.60.jar are ok, but 1.64 versions are not.

The version of apache commons-net is 3.1 .

Following is a small snippet of code that should work:

import java.io.ByteArrayOutputStream;
import java.security.SecureRandom;
import java.security.Security;

import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

import org.apache.commons.net.ftp.FTP;
import org.apache.commons.net.ftp.FTPReply;
import org.apache.commons.net.ftp.FTPSClient;
import org.bouncycastle.jce.provider.BouncyCastleProvider;
import org.bouncycastle.jsse.provider.BouncyCastleJsseProvider;
import org.junit.Test;


public class FtpsTest {

// Create a trust manager that does not validate certificate chains
TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {

    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
        return null;
    }

    public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {
    }

    public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {
    }
} };

@Test public void test() throws Exception {


    Security.insertProviderAt(new BouncyCastleProvider(), 1);
    Security.addProvider(new BouncyCastleJsseProvider());


    SSLContext sslContext = SSLContext.getInstance("TLS", new BouncyCastleJsseProvider());
    sslContext.init(null, trustAllCerts, new SecureRandom());
    org.apache.commons.net.ftp.FTPSClient ftpClient = new FTPSClient(sslContext);
    ByteArrayOutputStream out = null;
    try {

        ftpClient.connect("hostaname", 21);
        if (!FTPReply.isPositiveCompletion(ftpClient.getReplyCode())) {
            String msg = "Il server ftp ha rifiutato la connessione.";
            throw new Exception(msg);
        }
        if (!ftpClient.login("username", "pwd")) {
            String msg = "Il server ftp ha rifiutato il login con username:  username  e pwd:  password  .";
            ftpClient.disconnect();
            throw new Exception(msg);
        }


        ftpClient.enterLocalPassiveMode();
        ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
        ftpClient.setDataTimeout(60000);
        ftpClient.execPBSZ(0); // Set protection buffer size
        ftpClient.execPROT("P"); // Set data channel protection to private
        int bufSize = 1024 * 1024; // 1MB
        ftpClient.setBufferSize(bufSize);
        out = new ByteArrayOutputStream(bufSize);
        ftpClient.retrieveFile("remoteFileName", out);
        out.toByteArray();
    }
    finally {
        if (out != null) {
            out.close();
        }
        ftpClient.disconnect();

    }

}

}

You can use the functions in Python's built-in signal module to set up signal handlers in python. Specifically the signal.signal(signalnum, handler) function is used to register the handler function for signal signalnum.

I would probably do something along the lines of

<div id='search-logo-bar'><input type='text'/></div>

with css

div#search-logo-bar {
    padding-left:10%;
    background:#333 url(logo.png) no-repeat left center;
    background-size:10%;
}
input[type='text'] {
    display:block;
    width:100%;
}

• pyenv - manages different python versions,
• all others - create virtual environment (which has isolated python version and installed "requirements"),

pipenv want combine all, in addition to previous it installs "requirements" (into the active virtual environment or create its own if none is active)

So maybe you will be happy with pipenv only.

But I use: pyenv + pyenv-virtualenvwrapper, + pipenv (pipenv for installing requirements only).

In Debian:

1. apt install libffi-dev

2. install pyenv based on https://www.tecmint.com/pyenv-install-and-manage-multiple-python-versions-in-linux/, but..

3. .. but instead of pyenv-virtualenv install pyenv-virtualenvwrapper (which can be standalone library or pyenv plugin, here the 2nd option):

   pyenv install 3.9.0

   git clone https://github.com/pyenv/pyenv-virtualenvwrapper.git $(pyenv root)/plugins/pyenv-virtualenvwrapper

   into ~/.bashrc add: export $VIRTUALENVWRAPPER_PYTHON="/usr/bin/python3"

   source ~/.bashrc

   pyenv virtualenvwrapper

Then create virtual environments for your projects (workingdir must exist):

pyenv local 3.9.0  # to prevent 'interpreter not found' in mkvirtualenv
python -m pip install --upgrade pip setuptools wheel
mkvirtualenv <venvname> -p python3.9 -a <workingdir>

and switch between projects:

workon <venvname>
python -m pip install --upgrade pip setuptools wheel pipenv

Inside a project I have the file requirements.txt, without fixing the versions inside (if some version limitation is not neccessary). You have 2 possible tools to install them into the current virtual environment: pip-tools or pipenv. Lets say you will use pipenv:

pipenv install -r requirements.txt

this will create Pipfile and Pipfile.lock files, fixed versions are in the 2nd one. If you want reinstall somewhere exactly same versions then (Pipfile.lock must be present):

pipenv install

Remember that Pipfile.lock is related to some Python version and need to be recreated if you use a different one.

As you see I write requirements.txt. This has some problems: You must remove a removed package from Pipfile too. So writing Pipfile directly is probably better.

So you can see I use pipenv very poorly. Maybe if you will use it well, it can replace everything?

EDIT 2021.01: I have changed my stack to: pyenv + pyenv-virtualenvwrapper + poetry. Ie. I use no apt or pip installation of virtualenv or virtualenvwrapper, and instead I install pyenv's plugin pyenv-virtualenvwrapper. This is easier way.

Poetry is great for me:

poetry add <package>   # install single package
poetry remove <package>
poetry install   # if you remove poetry.lock poetry will re-calculate versions

This could be because your CSV file has embedded single or double quotes. If your CSV file is tab-delimited try opening it as:

c = csv.reader(f, delimiter='\t', quoting=csv.QUOTE_NONE)

I read three books and still did not understand patterns very well until I read Head First Design Patterns by OReilly. This book opened my eyes and really explained well.

While this does not address the OP's question, I had trouble with my bootstrap rows / columns while trying to use them in conjunction with Kendo ListView (even with the bootstrap-kendo css).

Adding the following css fixed the problem for me:

#myListView.k-widget, #catalog-items.k-widget * {
    -webkit-box-sizing: border-box;
    box-sizing: border-box;
}

Depending on your needs, you may also want to check out the classes CountDownLatch and CyclicBarrier in the java.util.concurrent package. They can be useful if you want your threads to wait for each other, or if you want more fine-grained control over the way your threads execute (e.g., waiting in their internal execution for another thread to set some state). You could also use a CountDownLatch to signal all of your threads to start at the same time, instead of starting them one by one as you iterate through your loop. The standard API docs have an example of this, plus using another CountDownLatch to wait for all threads to complete their execution.

You can make a menu for each fragment, and a global variable that mark which fragment is in use now. and check the value of the variable in onCreateOptionsMenu and inflate the correct menu

 @Override
     public boolean onCreateOptionsMenu(Menu menu) {
         if (fragment_it == 6) {
             MenuInflater inflater = getMenuInflater();
             inflater.inflate(R.menu.custom_actionbar, menu);
         }
     } 

It looks like you're using Python 3.0, in which print has turned into a callable function rather than a statement.

print('Hello world!')

Introduction to Algorithms by Cormen et. al. is a standard introductory algorithms book, and is used by many universities, including my own. It has pretty good coverage and is very approachable.

And anything by Robert Sedgewick is good too.

For C/C++ programs there's very good package gpp-compiler.

Shortcuts:

• To compile and run: F5
• To debug: F6

The solution for me was sooo dumb!!

I was using Python 3.8 in my environment. I made a new environment using Python 3.7, and the install worked fine.

source

I ended up doing the following and it works:

return DatabaseContext.Applications
     .Include("Children.ChildRelationshipType");

As others have pointed out, clone will do it. Be aware that clone of a hash makes a shallow copy. That is to say:

h1 = {:a => 'foo'} 
h2 = h1.clone
h1[:a] << 'bar'
p h2                # => {:a=>"foobar"}

What's happening is that the hash's references are being copied, but not the objects that the references refer to.

If you want a deep copy then:

def deep_copy(o)
  Marshal.load(Marshal.dump(o))
end

h1 = {:a => 'foo'}
h2 = deep_copy(h1)
h1[:a] << 'bar'
p h2                # => {:a=>"foo"}

deep_copy works for any object that can be marshalled. Most built-in data types (Array, Hash, String, &c.) can be marshalled.

Marshalling is Ruby's name for serialization. With marshalling, the object--with the objects it refers to--is converted to a series of bytes; those bytes are then used to create another object like the original.

I have just solved the same issue upon setting up my Windows 8.1 PC. Exactly like @George Papatheodorou mentioned above (sorry I cannot add a comment), Eclipse and JRE must be both 64 bit or 32 bit.

However, it seems for Windows 8/8.1 environment, you are going to get 32-bit JRE by default (and I do not know where to change that default for the download), as explained here: http://java.com/en/download/faq/win8_faq.xml

I was using 64-bit Eclipse so there was a discrepancy. I then installed 32-bit Eclipse and everything works fine this time.

So before bothering changing any environment variables, check your JRE and Eclipse version.

Of course you can use 64-bit JRE with 64-bit Eclipse. Just make sure they match because Windows 8.1 will give you 32-bit by default.

you can just do an svn add path/to/dir/* you'll get warning about anything already in version control but it will add everything that isn't.

The simulator puts the file in ~/Library/Developer/CoreSimulator/Devices/... but the path after /Devices is different for everyone.

Use this handy method. It returns the path of the temporary directory for the current user and takes no argument.

NSString * NSTemporaryDirectory ( void );

So in my ViewController class I usually put this line in my viewDidLoad just for a reference when I need to grab my CoreData stored file. Hope this helps.

  NSLog(@"FILE PATH :%@", NSTemporaryDirectory());

(Note: to go to the path, from the finder menu click on Go and type ~/Library to open hidden directory then in the Finder Window you can click on the path shown on your console.)

the problem mainly is because the width have to be == to the height, and in the case of bs, the height is set to auto so here is a fix for that in js instead

function img_circle() {
    $('.img-circle').each(function() {
        $w = $(this).width();
        $(this).height($w);
    });
}

$(document).ready(function() {
    img_circle();
});

$(window).resize(function() {
    img_circle();
});

Posting my answer to help someone, the top rated answer didn't solve my qualm.

When I implemented the following [from the top answer], my vertical scroll animation just jittered back and forth:

$(function () {
 $("#first").animate({
   width: '200px'
}, { duration: 200, queue: false });

$("#second").animate({
   width: '600px'
}, { duration: 200, queue: false });
});

I referred to: W3 Schools Set Interval and it solved my issue, namely the 'Syntax' section:

setInterval(function, milliseconds, param1, param2, ...)

Having my parameters of the form { duration: 200, queue: false } forced a duration of zero and it only looked at the parameters for guidance.

The long and short, here's my code, if you want to understand why it works, read the link or analyse the interval expected parameters:

var $scrollDiv = '#mytestdiv';
var $scrollSpeed = 1000;
var $interval = 800;

function configureRepeats() {
   window.setInterval(function () {
       autoScroll($scrollDiv, $scrollSpeed);
   }, $interval, { queue: false });
};

Where 'autoScroll' is:

    $($scrollDiv).animate({
        scrollTop: $($scrollDiv).get(0).scrollHeight
    }, { duration: $scrollSpeed });

    //Scroll to top immediately 
    $($scrollDiv).animate({
        scrollTop: 0
    }, 0);

Happy coding!

If you can use range v3 , you can use the reverse range adapter ranges::view::reverse which allows you to view the container in reverse.

A minimal working example:

#include <iostream>
#include <vector>
#include <range/v3/view.hpp>

int main()
{
    std::vector<int> intVec = {1, 2, 3, 4, 5, 6, 7, 8, 9};

    for (auto const& e : ranges::view::reverse(intVec)) {
        std::cout << e << " ";   
    }
    std::cout << std::endl;

    for (auto const& e : intVec) {
        std::cout << e << " ";   
    }
    std::cout << std::endl;
}

See DEMO 1.

Note: As per Eric Niebler, this feature will be available in C++20. This can be used with the <experimental/ranges/range> header. Then the for statement will look like this:

for (auto const& e : view::reverse(intVec)) {
       std::cout << e << " ";   
}

See DEMO 2

As it has been pointed out, it depends on the type. For built-in data types, it is best to pass by value. Even some very small structures, such as a pair of ints can perform better by passing by value.

Here is an example, assume you have an integer value and you want pass it to another routine. If that value has been optimized to be stored in a register, then if you want to pass it be reference, it first must be stored in memory and then a pointer to that memory placed on the stack to perform the call. If it was being passed by value, all that is required is the register pushed onto the stack. (The details are a bit more complicated than that given different calling systems and CPUs).

If you are doing template programming, you are usually forced to always pass by const ref since you don't know the types being passed in. Passing penalties for passing something bad by value are much worse than the penalties of passing a built-in type by const ref.

If you want to refer to calculated column on the "same query level" then you could use CROSS APPLY(Oracle 12c):

--Sample data:
CREATE TABLE tab(ColumnA NUMBER(10,2),ColumnB NUMBER(10,2),ColumnC NUMBER(10,2));

INSERT INTO tab(ColumnA, ColumnB, ColumnC) VALUES (2, 10, 2);
INSERT INTO tab(ColumnA, ColumnB, ColumnC) VALUES (3, 15, 6);
INSERT INTO tab(ColumnA, ColumnB, ColumnC) VALUES (7, 14, 3);
COMMIT;

Query:

SELECT
  ColumnA,
  ColumnB,
  sub.calccolumn1,
  sub.calccolumn1 / ColumnC AS calccolumn2
FROM tab t
CROSS APPLY (SELECT t.ColumnA + t.ColumnB AS calccolumn1 FROM dual) sub;

DBFiddle Demo

Please note that expression from CROSS APPLY/OUTER APPLY is available in other clauses too:

SELECT
  ColumnA,
  ColumnB,
  sub.calccolumn1,
  sub.calccolumn1 / ColumnC AS calccolumn2
FROM tab t
CROSS APPLY (SELECT t.ColumnA + t.ColumnB AS calccolumn1 FROM dual) sub
WHERE sub.calccolumn1 = 12;
-- GROUP BY ...
-- ORDER BY ...;

This approach allows to avoid wrapping entire query with outerquery or copy/paste same expression in multiple places(with complex one it could be hard to maintain).

In fact you cannot do it easily right now (at the time I am writing this message). I will try to explain why.

First of all, the glibc is no more, it has been subsumed by the eglibc project. And, the Debian distribution switched to eglibc some time ago (see here and there and even on the glibc source package page). So, you should consider installing the eglibc package through this kind of command:

apt-get install libc6-amd64 libc6-dev libc6-dbg

Replace amd64 by the kind of architecture you want (look at the package list here).

Unfortunately, the eglibc package version is only up to 2.13 in unstable and testing. Only the experimental is providing a 2.17 version of this library. So, if you really want to have it in 2.15 or more, you need to install the package from the experimental version (which is not recommended). Here are the steps to achieve as root:

1. Add the following line to the file /etc/apt/sources.list:

   deb http://ftp.debian.org/debian experimental main
   

2. Update your package database:

   apt-get update
   

3. Install the eglibc package:

   apt-get -t experimental install libc6-amd64 libc6-dev libc6-dbg
   

4. Pray...

Well, that's all folks.

Just because I did not see it mentioned.

If 2016+, here is yet another option to dynamically unpivot data without actually using Dynamic SQL.

Example

Declare @YourTable Table ([ID] varchar(50),[Col1] varchar(50),[Col2] varchar(50))
Insert Into @YourTable Values 
 (1,'A','B')
,(2,'R','C')
,(3,'X','D')

Select A.[ID]
      ,Item  = B.[Key]
      ,Value = B.[Value]
 From  @YourTable A
 Cross Apply ( Select * 
                From  OpenJson((Select A.* For JSON Path,Without_Array_Wrapper )) 
                Where [Key] not in ('ID','Other','Columns','ToExclude')
             ) B

Returns

ID  Item    Value
1   Col1    A
1   Col2    B
2   Col1    R
2   Col2    C
3   Col1    X
3   Col2    D

For Swift:

AVPlayer:

let player = AVPlayer(URL: NSURL(string: "http://www.sample.com/movie.mov"))
if (player.rate != 0 && player.error == nil) {
   println("playing")
}

Update:
player.rate > 0 condition changed to player.rate != 0 because if video is playing in reverse it can be negative thanks to Julian for pointing out.
Note: This might look same as above(Maz's) answer but in Swift '!player.error' was giving me a compiler error so you have to check for error using 'player.error == nil' in Swift.(because error property is not of 'Bool' type)

AVAudioPlayer:

if let theAudioPlayer =  appDelegate.audioPlayer {
   if (theAudioPlayer.playing) {
       // playing
   }
}

AVQueuePlayer:

if let theAudioQueuePlayer =  appDelegate.audioPlayerQueue {
   if (theAudioQueuePlayer.rate != 0 && theAudioQueuePlayer.error == nil) {
       // playing
   }
}

Just note the difference between the range operators:

3..10  # includes 10
3...10 # doesn't include 10

Most of solutions use static width here. But it can be sometimes wrong for some reasons.

Example: I had table with many columns. Most of them are narrow (static width). But the main column should be as wide as possible (depends on screen size).

HTML:

<table style="width: 100%">
  <tr>
    <td style="width: 60px;">narrow</td>
    <td>
      <span class="cutwrap" data-cutwrap="dynamic column can have really long text which can be wrapped on two rows, but we just need not wrapped texts using as much space as possible">
        dynamic column can have really long text which can be wrapped on two rows
        but we just need not wrapped texts using as much space as possible
      </span>
    </td>
  </tr>
</table>

CSS:

.cutwrap {
  position: relative;
  overflow: hidden;
  display: block;
  width: 100%;
  height: 18px;
  white-space: normal;
  color: transparent !important;
}
.cutwrap::selection {
  color: transparent !important;
}
.cutwrap:before {
  content: attr(data-cutwrap);
  position: absolute;
  left: 0;
  right: 0;
  overflow: hidden;
  text-overflow: ellipsis;
  white-space: nowrap;
  color: #333;
}
/* different styles for links */
a.cutwrap:before {
  text-decoration: underline;
  color: #05c;

For IntelliJ14 you may have to change the bytecode version w.r.t. the JDK you are using (in the global settings):

If you doing from windows folder, I mean if you are using the kafka from windows machine

kafka-console-consumer.bat --bootstrap-server localhost:9092 --<topic-name> test --from-beginning

cout << "Enter amount of spaces you would like (integer)" << endl; 
cin >> n;
//print n spaces
for (int i = 0; i < n; ++i)
{
   cout << " " ;
}
cout <<endl;

solution: On the server you are trying to clone to or push from cat ~/.ssh/id_rsa.pub Go to GitHub, settings, SSH and GPG Keys , New SSH key paste key.

You can't really compare NA with another value, so using == would not work. Consider the following:

NA == NA
# [1] NA

You can just change your comparison from == to %in%:

ifelse(is.na(test$time) | test$type %in% "A", NA, "1")
# [1] NA  "1" NA  "1"

Regarding your other question,

I could get this to work with my existing code if I could somehow change the result of is.na(test$type) to return FALSE instead of TRUE, but I'm not sure how to do that.

just use ! to negate the results:

!is.na(test$time)
# [1]  TRUE  TRUE FALSE  TRUE

A little late to the party, but if you are looking for a solution like Yury's the following code will help you identify if the issue is related to a self-sign certificate and, if so ignore the self-sign error. You could obviously check for other SSL errors if you so desired.

The code we use (courtesy of Microsoft - http://msdn.microsoft.com/en-us/library/office/dd633677(v=exchg.80).aspx) is as follows:

  private static bool CertificateValidationCallBack(
         object sender,
         System.Security.Cryptography.X509Certificates.X509Certificate certificate,
         System.Security.Cryptography.X509Certificates.X509Chain chain,
         System.Net.Security.SslPolicyErrors sslPolicyErrors)
    {
  // If the certificate is a valid, signed certificate, return true.
  if (sslPolicyErrors == System.Net.Security.SslPolicyErrors.None)
  {
    return true;
  }

  // If there are errors in the certificate chain, look at each error to determine the cause.
  if ((sslPolicyErrors & System.Net.Security.SslPolicyErrors.RemoteCertificateChainErrors) != 0)
  {
    if (chain != null && chain.ChainStatus != null)
    {
      foreach (System.Security.Cryptography.X509Certificates.X509ChainStatus status in chain.ChainStatus)
      {
        if ((certificate.Subject == certificate.Issuer) &&
           (status.Status == System.Security.Cryptography.X509Certificates.X509ChainStatusFlags.UntrustedRoot))
        {
          // Self-signed certificates with an untrusted root are valid. 
          continue;
        }

Thanks to cryo for improved version that I based my tested code below:

I hit this question as I was trying to get something similar working using Generics. Taking some of the answers and adding getClass().isArray() I get the following that seems to work.

public class TypeTester <T extends Number>{

<T extends Object> String tester(T ToTest){

    if (ToTest instanceof Integer) return ("Integer");
    else if(ToTest instanceof Double) return ("Double");
    else if(ToTest instanceof Float) return ("Float");
    else if(ToTest instanceof String) return ("String");
    else if(ToTest.getClass().isArray()) return ("Array");
    else return ("Unsure");
}
}

I call it with this where the myArray part was simply to get an Array into callFunction.tester() to test it.

public class Generics {
public static void main(String[] args) {
    int [] myArray = new int [10];

    TypeTester<Integer> callFunction = new TypeTester<Integer>();
    System.out.println(callFunction.tester(myArray));
}
}

You can swap out the myArray in the final line for say 10.2F to test Float etc

It is possible to print a 15 decimal number in C++ using the following:

#include <iomanip>
#include <iostream>

cout << fixed << setprecision(15) << " The Real_Pi is: " << real_pi << endl;
cout << fixed << setprecision(15) << " My Result_Pi is: " << my_pi << endl;
cout << fixed << setprecision(15) << " Processing error is: " << Error_of_Computing << endl;
cout << fixed << setprecision(15) << " Processing time is: " << End_Time-Start_Time << endl;
_getch();

return 0;

using DbUtils...

The only problem I had with that lib was that sometimes you have relationships in your bean classes, DBUtils does not map that. It only maps the properties in the class of the bean, if you have other complex properties (refering other beans due to DB relationship) you'd have to create "indirect setters" as I call, which are setters that put values into those complex properties's properties.

If you are accessing your repositories over the SSH protocol, you will receive a warning message each time your client connects to a new IP address for github.com. As long as the IP address from the warning is in the range of IP addresses , you shouldn't be concerned. Specifically, the new addresses that are being added this time are in the range from 192.30.252.0 to 192.30.255.255. The warning message looks like this:

Warning: Permanently added the RSA host key for IP address '$IP' to the list of

The key with ordering is to set the levels of the factor in the order you want. An ordered factor is not required; the extra information in an ordered factor isn't necessary and if these data are being used in any statistical model, the wrong parametrisation might result — polynomial contrasts aren't right for nominal data such as this.

## set the levels in order we want
theTable <- within(theTable, 
                   Position <- factor(Position, 
                                      levels=names(sort(table(Position), 
                                                        decreasing=TRUE))))
## plot
ggplot(theTable,aes(x=Position))+geom_bar(binwidth=1)

In the most general sense, we simply need to set the factor levels to be in the desired order. If left unspecified, the levels of a factor will be sorted alphabetically. You can also specify the level order within the call to factor as above, and other ways are possible as well.

theTable$Position <- factor(theTable$Position, levels = c(...))

I think what you are looking for is something like this:

$(field).closest("form").submit();

For example, to handle the onchange event, you would have this:

$(select your fields here).change(function() {
    $(this).closest("form").submit();
});

If, for some reason you aren't using jQuery 1.3 or above, you can call parents instead of closest.

If your <option> elements don't have value attributes, then you can just use .val:

$selectElement.val("text_you're_looking_for")

However, if your <option> elements have value attributes, or might do in future, then this won't work, because whenever possible .val will select an option by its value attribute instead of by its text content. There's no built-in jQuery method that will select an option by its text content if the options have value attributes, so we'll have to add one ourselves with a simple plugin:

/*
  Source: https://stackoverflow.com/a/16887276/1709587

  Usage instructions:

  Call

      jQuery('#mySelectElement').selectOptionWithText('target_text');

  to select the <option> element from within #mySelectElement whose text content
  is 'target_text' (or do nothing if no such <option> element exists).
*/
jQuery.fn.selectOptionWithText = function selectOptionWithText(targetText) {
    return this.each(function () {
        var $selectElement, $options, $targetOption;

        $selectElement = jQuery(this);
        $options = $selectElement.find('option');
        $targetOption = $options.filter(
            function () {return jQuery(this).text() == targetText}
        );

        // We use `.prop` if it's available (which it should be for any jQuery
        // versions above and including 1.6), and fall back on `.attr` (which
        // was used for changing DOM properties in pre-1.6) otherwise.
        if ($targetOption.prop) {
            $targetOption.prop('selected', true);
        } 
        else {
            $targetOption.attr('selected', 'true');
        }
    });
}

Just include this plugin somewhere after you add jQuery onto the page, and then do

jQuery('#someSelectElement').selectOptionWithText('Some Target Text');

to select options.

The plugin method uses filter to pick out only the option matching the targetText, and selects it using either .attr or .prop, depending upon jQuery version (see .prop() vs .attr() for explanation).

Here's a JSFiddle you can use to play with all three answers given to this question, which demonstrates that this one is the only one to reliably work: http://jsfiddle.net/3cLm5/1/

Yes, You can do it in a simple way. See below code of lines.

URL - http://localhost:8080/get/request/multiple/param/by/map?name='abc' & id='123'

 @GetMapping(path = "/get/request/header/by/map")
    public ResponseEntity<String> getRequestParamInMap(@RequestParam Map<String,String> map){
        // Do your business here 
        return new ResponseEntity<String>(map.toString(),HttpStatus.OK);
    } 

While probably not as clean looking as the IConvertible approach, you could always use the straightforward checking typeof(T) to return a T:

public static T ReturnType<T>(string stringValue)
{
    if (typeof(T) == typeof(int))
        return (T)(object)1;
    else if (typeof(T) == typeof(FooBar))
        return (T)(object)new FooBar(stringValue);
    else
        return default(T);
}

public class FooBar
{
    public FooBar(string something)
    {}
}

Enumerate the subkeys of HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP. Each subkey is a .NET version. It should have Install=1 value if it's present on the machine, an SP value that shows the service pack and an MSI=1 value if it was installed using an MSI. (.NET 2.0 on Windows Vista doesn't have the last one for example, as it is part of the OS.)

You can use [] to extract values from a QueryDict object like you would any ordinary dictionary.

# HTTP POST variables
request.POST['section'] # => [39]
request.POST['MAINS'] # => [137]

# HTTP GET variables
request.GET['section'] # => [39]
request.GET['MAINS'] # => [137]

# HTTP POST and HTTP GET variables (Deprecated since Django 1.7)
request.REQUEST['section'] # => [39]
request.REQUEST['MAINS'] # => [137]

Use itertools.combinations(mylist, 2)

    print x,y

$.getJSON is an asynchronous request, meaning the code will continue to run even though the request is not yet done. You should trigger the second request when the first one is done, one of the choices you seen already in ComFreek's answer.

Alternatively you could use jQuery's $.when/.then(), similar to this:

var input = "netuetamundis";  var sID;  $(document).ready(function () {     $.when($.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/" + input + "?api_key=API_KEY_HERE", function () {         obj = name;         sID = obj.id;         console.log(sID);     })).then(function () {         $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function (stats) {             console.log(stats);         });     }); }); 

This would be more open for future modification and separates out the responsibility for the first call to know about the second call.

The first call can simply complete and do it's own thing not having to be aware of any other logic you may want to add, leaving the coupling of the logic separated.

    }

Therefore, I would like to separate the string by the furthest delimiter.

I know this is an old question, but this is a simple requirement for which SUBSTR and INSTR would suffice. REGEXP are still slower and CPU intensive operations than the old subtsr and instr functions.

SQL> WITH DATA AS
  2    ( SELECT 'F/P/O' str FROM dual
  3    )
  4  SELECT SUBSTR(str, 1, Instr(str, '/', -1, 1) -1) part1,
  5         SUBSTR(str, Instr(str, '/', -1, 1) +1) part2
  6  FROM DATA
  7  /

PART1 PART2
----- -----
F/P   O

As you said you want the furthest delimiter, it would mean the first delimiter from the reverse.

You approach was fine, but you were missing the start_position in INSTR. If the start_position is negative, the INSTR function counts back start_position number of characters from the end of string and then searches towards the beginning of string.

The use of the argument, conventionally called self isn't as hard to understand, as is why is it necessary? Or as to why explicitly mention it? That, I suppose, is a bigger question for most users who look up this question, or if it is not, they will certainly have the same question as they move forward learning python. I recommend them to read these couple of blogs:

1: Use of self explained

Note that it is not a keyword.

The first argument of every class method, including init, is always a reference to the current instance of the class. By convention, this argument is always named self. In the init method, self refers to the newly created object; in other class methods, it refers to the instance whose method was called. For example the below code is the same as the above code.

2: Why do we have it this way and why can we not eliminate it as an argument, like Java, and have a keyword instead

Another thing I would like to add is, an optional self argument allows me to declare static methods inside a class, by not writing self.

Code examples:

class MyClass():
    def staticMethod():
        print "This is a static method"

    def objectMethod(self):
        print "This is an object method which needs an instance of a class, and that is what self refers to"

PS:This works only in Python 3.x.

In previous versions, you have to explicitly add @staticmethod decorator, otherwise self argument is obligatory.

This regex works for C#, PCRE and Go to name a few.

It doesn't work for JavaScript on Chrome from what RegexBuddy says. But there's already an example for that here.

This main part of this is:

\p{L}

which represents \p{L} or \p{Letter} any kind of letter from any language.`

The full regex itself: [^\w\d\s:\p{L}]

Example: https://regex101.com/r/K59PrA/2

you can use cURL library for posting data: http://www.php.net/curl

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_URL, "http://websiteURL");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "XML=".$xmlcontent."&password=".$password."&etc=etc");
$content=curl_exec($ch);

where postfield contains XML you need to send - you will need to name the postfield the API service (Clickatell I guess) expects

Under Linux and other Unix-related systems, there are only two characters that cannot appear in the name of a file or directory, and those are NUL '\0' and slash '/'. The slash, of course, can appear in a path name, separating directory components.

Rumour¹ has it that Steven Bourne (of 'shell' fame) had a directory containing 254 files, one for every single letter (character code) that can appear in a file name (excluding /, '\0'; the name . was the current directory, of course). It was used to test the Bourne shell and routinely wrought havoc on unwary programs such as backup programs.

Other people have covered the Windows rules.

Note that MacOS X has a case-insensitive file system.

When Steve Bourne was writing his Unix shell (which came to be known as the Bourne shell), he made a directory of 254 files with one-character names, one for each byte value except '\0' and slash, the two characters that cannot appear in Unix file names. He used that directory for all manner of tests of pattern-matching and tokenization. (The test directory was of course created by a program.) For years afterwards, that directory was the bane of file-tree-walking programs; it tested them to destruction.

^{Note that the directory must have contained entries . and .., so it was arguably 253 files (and 2 directories), or 255 name entries, rather than 254 files. This doesn't affect the effectiveness of the anecdote, or the careful testing it describes.}

Try enabling vertical mode, using \G to execute the query instead of ;:

mysql> SELECT * FROM sometable \G

Your results will be listed in the vertical mode, so each column value will be printed on a separate line. The output will be narrower but obviously much longer.

From now you can also :

Action<int> action = (o) => Thread.Sleep(o);
int param = 10;
await new TaskFactory().StartNew(action, param)

You can also use something like this

This really helped me, thanks Nick Uraltsev for your answer.

For those of you using nodejs with cors:

...
const cors = require('cors');

const corsOptions = {
  exposedHeaders: 'Authorization',
};

app.use(cors(corsOptions));
...

In the case you are sending the response in the way of res.header('Authorization', `Bearer ${token}`).send();

You can implement a hasRole() method as below - (This is tested on spring security 3.0.x not sure about other versions.)

  protected final boolean hasRole(String role) {
    boolean hasRole = false;
    UserDetails userDetails = getUserDetails();
    if (userDetails != null) {
      Collection<GrantedAuthority> authorities = userDetails.getAuthorities();
      if (isRolePresent(authorities, role)) {
        hasRole = true;
      }
    } 
    return hasRole;
  }
  /**
   * Get info about currently logged in user
   * @return UserDetails if found in the context, null otherwise
   */
  protected UserDetails getUserDetails() {
    Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();
    UserDetails userDetails = null;
    if (principal instanceof UserDetails) {
      userDetails = (UserDetails) principal;
    }
    return userDetails;
  }
  /**
   * Check if a role is present in the authorities of current user
   * @param authorities all authorities assigned to current user
   * @param role required authority
   * @return true if role is present in list of authorities assigned to current user, false otherwise
   */
  private boolean isRolePresent(Collection<GrantedAuthority> authorities, String role) {
    boolean isRolePresent = false;
    for (GrantedAuthority grantedAuthority : authorities) {
      isRolePresent = grantedAuthority.getAuthority().equals(role);
      if (isRolePresent) break;
    }
    return isRolePresent;
  }

Some new java online compiler and runner:

1. Java Launch
2. Srikanthdaggumalli

These sites are in under development. But you can view the compilation errors, Runtime Exceptions as well as output of a java program by clicking on the TryItYourself link.

Use Passay library which is powerful api.

I had the same problem. Solution in my case: run CMD as ADMINISTRATOR. then type and execute: "lsnrctl start" wait about 2 minutes then should work. (in my case was only 50 seconds, but just to be on the safe side)

If you want to be in a foreach loop, then foreach($array as $key => $value) is definitely the recommended approach. Take advantage of simple syntax when a language offers it.

Currently, the link dlptest is working fine.

The files will only be stored for 30 minutes before being deleted.

Use float fabsf (float n) for float values.

Use double fabs (double n) for double values.

Use long double fabsl(long double) for long double values.

Use abs(int) for int values.

Note that You can configure Apache so that all files With .inc extension are forbidden to be retrieved by visiting URL directly.

I have also faced this issue on my MacOS, I used these simple steps and it worked for me.

Just open the terminal and go to your project folder where you what to start ngrok and then unzip downloaded file.

$ unzip /path/to/ngrok.zip

After doing this you don't need to authenticate ngrok, just run this command:

./ngrok  http 80

It should work now.

I created this prototype to prepend elements to parent element.

Node.prototype.prependChild = function (child: Node) {
    this.insertBefore(child, this.firstChild);
    return this;
};

Here is an approach that updates a DateTimeFormatter pattern with the correct suffix literal if it finds the pattern d'00', e.g. for day of month 1 it would be replaced with d'st'. Once the pattern has been updated it can then just be fed into the DateTimeFormatter to do the rest.

private static String[] suffixes = {"th", "st", "nd", "rd"};

private static String updatePatternWithDayOfMonthSuffix(TemporalAccessor temporal, String pattern) {
    String newPattern = pattern;
    // Check for pattern `d'00'`.
    if (pattern.matches(".*[d]'00'.*")) {
        int dayOfMonth = temporal.get(ChronoField.DAY_OF_MONTH);
        int relevantDigits = dayOfMonth < 30 ? dayOfMonth % 20 : dayOfMonth % 30;
        String suffix = suffixes[relevantDigits <= 3 ? relevantDigits : 0];
        newPattern = pattern.replaceAll("[d]'00'", "d'" + suffix + "'");
    }

    return newPattern;
}

It does require that the original pattern is updated just prior to every formatting call, e.g.

public static String format(TemporalAccessor temporal, String pattern) {
    DateTimeFormatter formatter = DateTimeFormatter.ofPattern(updatePatternWithDayOfMonthSuffix(temporal, pattern));
    return formatter.format(temporal);
}

So this is useful if the formatting pattern is defined outside of Java code, e.g. a template, where as if you can define the pattern in Java then the answer by @OleV.V. might be more appropriate

I know this seems to be already answered, but I ran into a specific case, and I feel most answers miss the point.

The overflow:hidden answers cover 90% of the cases. That's more or less the "sticky nav" scenario.

But the sticky behavior is best used within the height of a container. Think of a newsletter form in the right column of your website that scrolls down with the page. If your sticky element is the only child of the container, the container is the exact same size, and there's no room to scroll.

Your container needs to be the height you expect your element to scroll within. Which in my "right column" scenario is the height of the left column. The best way to achieve this is to use display:table-cell on the columns. If you can't, and are stuck with float:right and such like I was, you'll have to either guess the left column height of compute it with Javascript.

another way

SELECT COUNT(*) FROM tbl_debug WHERE TO_DAYS(`when`) < TO_DAYS(NOW())-30 ;

I know this is old, but also make sure that none of your docker containers are already on port 80. That was my issue.

With the release of RecyclerView library, now you can align a list of images bind with text easily. You can use LinearLayoutManager to specify the direction in which you would like to orient your list, either vertical or horizontal as shown below.

You can download a full working demo from this post

Thought to add this here in case someone finds it useful. @ostrokach already mentioned how you can merge the data frames across rows which is

df_row_merged = pd.concat([df_a, df_b], ignore_index=True)

To merge across columns, you can use the following syntax:

df_col_merged = pd.concat([df_a, df_b], axis=1)

There are a million answers, but here's another one: copy the files into a new package, delete the old package and rename the new package to the old package's name.

While I would have gone with Piotr's answer (because it's all in one line), I was surprised that your sample is closer to your solution than you think. From what you have, you simply assign the model value before you use the Html helper method.

@{Model.RequiredProperty = "default";}
@Html.HiddenFor(model => model.RequiredProperty)

Yes, it absolutely is - assuming you've got the appropriate security permissions. Use Field.setAccessible(true) first if you're accessing it from a different class.

import java.lang.reflect.*;

class Other
{
    private String str;
    public void setStr(String value)
    {
        str = value;
    }
}

class Test
{
    public static void main(String[] args)
        // Just for the ease of a throwaway test. Don't
        // do this normally!
        throws Exception
    {
        Other t = new Other();
        t.setStr("hi");
        Field field = Other.class.getDeclaredField("str");
        field.setAccessible(true);
        Object value = field.get(t);
        System.out.println(value);
    }
}

And no, you shouldn't normally do this... it's subverting the intentions of the original author of the class. For example, there may well be validation applied in any situation where the field can normally be set, or other fields may be changed at the same time. You're effectively violating the intended level of encapsulation.

I faced this problem while trying to extend an existing class from GitHub. I'm gonna try to explain myself, first writing the class as I though it should be, and then the class as it is now.

What I though

namespace mycompany\CutreApi;

use mycompany\CutreApi\ClassOfVendor;

class CutreApi extends \vendor\AwesomeApi\AwesomeApi
{
   public function whatever(): ClassOfVendor
   {
        return new ClassOfVendor();
   }
}

What I've finally done

namespace mycompany\CutreApi;

use \vendor\AwesomeApi\ClassOfVendor;

class CutreApi extends \vendor\AwesomeApi\AwesomeApi
{
   public function whatever(): ClassOfVendor
   {
        return new \mycompany\CutreApi\ClassOfVendor();
   }
}

So seems that this errror raises also when you're using a method that return a namespaced class, and you try to return the same class but with other namespace. Fortunately I have found this solution, but I do not fully understand the benefit of this feature in php 7.2, for me it is normal to rewrite existing class methods as you need them, including the redefinition of input parameters and / or even behavior of the method.

One downside of the previous aproach, is that IDE's could not recognise the new methods implemented in \mycompany\CutreApi\ClassOfVendor(). So, for now, I will go with this implementation.

Currently done

namespace mycompany\CutreApi;

use mycompany\CutreApi\ClassOfVendor;

class CutreApi extends \vendor\AwesomeApi\AwesomeApi
{
   public function getWhatever(): ClassOfVendor
   {
        return new ClassOfVendor();
   }
}

So, instead of trying to use "whatever" method, I wrote a new one called "getWhatever". In fact both of them are doing the same, just returning a class, but with diferents namespaces as I've described before.

Hope this can help someone.

The question is already answered but I wanted to point out another solution which is fast and works if length is not meant to be changed at run-time. Use macro #define before main() to define length and in main() your initialization will work:

#define length 10

int main()
{
    int boardAux[length][length] = {{0}};
}

Macros are run before the actual compilation and length will be a compile-time constant (as referred by David Rodríguez in his answer). It will actually substitute length with 10 before compilation.

The code below works with Last, First M name strings. Substitute "Name" with your name string column name. Since you have a period as a final character when there is a middle initial, you would replace the 2's with 3's in each of the lines (2, 6, and 8)- and change "RIGHT(Name, 1)" to "RIGHT(Name, 2)" in line 8.

SELECT  SUBSTRING(Name, 1, CHARINDEX(',', Name) - 1) LastName ,
CASE WHEN LEFT(RIGHT(Name, 2), 1) <> ' '
     THEN LTRIM(SUBSTRING(Name, CHARINDEX(',', Name) + 1, 99))
     ELSE LEFT(LTRIM(SUBSTRING(Name, CHARINDEX(',', Name) + 1, 99)),
               LEN(LTRIM(SUBSTRING(Name, CHARINDEX(',', Name) + 1, 99)))
               - 2)
END FirstName ,
CASE WHEN LEFT(RIGHT(Name, 2), 1) = ' ' THEN RIGHT(Name, 1)
     ELSE NULL
END MiddleName

I was looking for a more complex apk filename renaming option and I wrote this solution that renames the apk with the following data:

• flavor
• build type
• version
• date

You would get an apk like this: myProject_dev_debug_1.3.6_131016_1047.apk.

You can find the whole answer here. Hope it helps!

In the build.gradle:

android {

    ...

    buildTypes {
        release {
            minifyEnabled true
            ...
        }
        debug {
            minifyEnabled false
        }
    }

    productFlavors {
        prod {
            applicationId "com.feraguiba.myproject"
            versionCode 3
            versionName "1.2.0"
        }
        dev {
            applicationId "com.feraguiba.myproject.dev"
            versionCode 15
            versionName "1.3.6"
        }
    }

    applicationVariants.all { variant ->
        variant.outputs.all { output ->
            def project = "myProject"
            def SEP = "_"
            def flavor = variant.productFlavors[0].name
            def buildType = variant.variantData.variantConfiguration.buildType.name
            def version = variant.versionName
            def date = new Date();
            def formattedDate = date.format('ddMMyy_HHmm')

            def newApkName = project + SEP + flavor + SEP + buildType + SEP + version + SEP + formattedDate + ".apk"

            outputFileName = new File(newApkName)
        }
    }
}

There are a couple of ways to achieve what you want, depending on the circumstances.

The most common scenario (which is what yours sounds like) is when a child Activity is used to get user input - such as choosing a contact from a list or entering data in a dialog box. In this case you should use startActivityForResult to launch your child Activity.

This provides a pipeline for sending data back to the main Activity using setResult. The setResult method takes an int result value and an Intent that is passed back to the calling Activity.

Intent resultIntent = new Intent();
// TODO Add extras or a data URI to this intent as appropriate.
resultIntent.putExtra("some_key", "String data"); 
setResult(Activity.RESULT_OK, resultIntent);
finish();

To access the returned data in the calling Activity override onActivityResult. The requestCode corresponds to the integer passed in in the startActivityForResult call, while the resultCode and data Intent are returned from the child Activity.

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
  super.onActivityResult(requestCode, resultCode, data);
  switch(requestCode) {
    case (MY_CHILD_ACTIVITY) : {
      if (resultCode == Activity.RESULT_OK) {
        // TODO Extract the data returned from the child Activity.
        String returnValue = data.getStringExtra("some_key");
      }
      break;
    } 
  }
}

Try xcorr, it's a built-in function in MATLAB for cross-correlation:

c = xcorr(A_1, A_2);

However, note that it requires the Signal Processing Toolbox installed. If not, you can look into the corrcoef command instead.

Automated Tasks: Cron

Cron is a time-based scheduling service in Linux / Unix-like computer operating systems. Cron job are used to schedule commands to be executed periodically. You can setup commands or scripts, which will repeatedly run at a set time. Cron is one of the most useful tool in Linux or UNIX like operating systems. The cron service (daemon) runs in the background and constantly checks the /etc/crontab file, /etc/cron./* directories. It also checks the /var/spool/cron/ directory.

Configuring Cron Tasks

In the following example, the crontab command shown below will activate the cron tasks automatically every ten minutes:

*/10 * * * * /usr/bin/php /opt/test.php

In the above sample, the */10 * * * * represents when the task should happen. The first figure represents minutes – in this case, on every "ten" minute. The other figures represent, respectively, hour, day, month and day of the week.

* is a wildcard, meaning "every time".

Start with finding out your PHP binary by typing in command line:

whereis php

The output should be something like:

php: /usr/bin/php /etc/php.ini /etc/php.d /usr/lib64/php /usr/include/php /usr/share/php /usr/share/man/man1/php.1.gz

Specify correctly the full path in your command.

Type the following command to enter cronjob:

crontab -e

To see what you got in crontab.

EDIT 1:

To exit from vim editor without saving just click:

Shift+:

And then type q!

In case you need short unique IDs as your filename, try shortuuid, shortuuid uses lowercase and uppercase letters and digits, and removing similar-looking characters such as l, 1, I, O and 0.

>>> import shortuuid
>>> shortuuid.uuid()
'Tw8VgM47kSS5iX2m8NExNa'
>>> len(ui)
22

compared to

>>> import uuid
>>> unique_filename = str(uuid.uuid4())
>>> len(unique_filename)
36
>>> unique_filename
'2d303ad1-79a1-4c1a-81f3-beea761b5fdf'

For Angular 1.3+ (credits to @Tom)

Use an alias expression (Docs: Angular 1.3.0: ngRepeat, scroll down to the Arguments section):

<div ng-repeat="person in data | filter:query as filtered">
</div>

For Angular prior to 1.3

Assign the results to a new variable (e.g. filtered) and access it:

<div ng-repeat="person in filtered = (data | filter: query)">
</div>

Display the number of results:

Showing {{filtered.length}} Persons

Update: For people that still come across this, Postman is your best bet now: https://www.getpostman.com/apps

RestClient is my favorite. It's Java based. I think it should meet your needs quite nicely. I particularly like the Auth suppport.

https://github.com/wiztools/rest-client

Based on Andi Wilkinson's answer (the second one), I improved a little, make sure the center of the image is shown (like the accepted answer did):

HTML:

<div class="crop">
   <img src="img.png">
</div>

CSS:

.crop{
  height: 150px;
  width: 200px;
  overflow: hidden;
}
.crop img{
  width: 100%;
  height: auto;
  position: relative;
  top: 50%;
  -webkit-transform: translateY(-50%); /* Ch <36, Saf 5.1+, iOS < 9.2, An =<4.4.4 */
  -ms-transform: translateY(-50%); /* IE 9 */
  transform: translateY(-50%); /* IE 10, Fx 16+, Op 12.1+ */
}

Try if that works

sc = spark.sparkContext

# Infer the schema, and register the DataFrame as a table.
schemaPeople = spark.createDataFrame(RddName)
schemaPeople.createOrReplaceTempView("RddName")

Here is an update to @GiridharKamik answer above with the latest version of Rxjs.

import { Injectable } from '@angular/core';
import { Observable, BehaviorSubject, fromEvent } from 'rxjs';
import { pluck, distinctUntilChanged, map } from 'rxjs/operators';

@Injectable()
export class WindowService {
    height$: Observable<number>;
    constructor() {
        const windowSize$ = new BehaviorSubject(getWindowSize());

        this.height$ = windowSize$.pipe(pluck('height'), distinctUntilChanged());

        fromEvent(window, 'resize').pipe(map(getWindowSize))
            .subscribe(windowSize$);
    }

}

function getWindowSize() {
    return {
        height: window.innerHeight
        //you can sense other parameters here
    };
};

found the solution with AND condition:

  $trainstrength = "UPDATE user_character SET strength_trains = strength_trains + 1, trained_strength = trained_strength +1, character_gold = character_gold - $gold_to_next_strength WHERE ID = $currentUser AND character_gold > $gold_to_next_strength";

Another alternative is to use a lambda:

ent.bind("<Return>", (lambda event: name_of_function()))

Full code:

from tkinter import *
from tkinter.messagebox import showinfo

def reply(name):
    showinfo(title="Reply", message = "Hello %s!" % name)


top = Tk()
top.title("Echo")
top.iconbitmap("Iconshock-Folder-Gallery.ico")

Label(top, text="Enter your name:").pack(side=TOP)
ent = Entry(top)
ent.bind("<Return>", (lambda event: reply(ent.get())))
ent.pack(side=TOP)
btn = Button(top,text="Submit", command=(lambda: reply(ent.get())))
btn.pack(side=LEFT)

top.mainloop()

As you can see, creating a lambda function with an unused variable "event" solves the problem.

You should use URL and URLSearchParams native functions:

let url = new URL("https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8&q=mdn%20query%20string")_x000D_
let params = new URLSearchParams(url.search);_x000D_
let sourceid = params.get('sourceid') // 'chrome-instant'_x000D_
let q = params.get('q') // 'mdn query string'_x000D_
let ie = params.has('ie') // true_x000D_
params.append('ping','pong')_x000D_
_x000D_
console.log(sourceid)_x000D_
console.log(q)_x000D_
console.log(ie)_x000D_
console.log(params.toString())_x000D_
console.log(params.get("ping"))

This indicates the linux has delivered a SIGTERM to your process. This is usually at the request of some other process (via kill()) but could also be sent by your process to itself (using raise()). This signal requests an orderly shutdown of your process.

If you need a quick cheatsheet of signal numbers, open a bash shell and:

$ kill -l
 1) SIGHUP   2) SIGINT   3) SIGQUIT  4) SIGILL
 5) SIGTRAP  6) SIGABRT  7) SIGBUS   8) SIGFPE
 9) SIGKILL 10) SIGUSR1 11) SIGSEGV 12) SIGUSR2
13) SIGPIPE 14) SIGALRM 15) SIGTERM 16) SIGSTKFLT
17) SIGCHLD 18) SIGCONT 19) SIGSTOP 20) SIGTSTP
21) SIGTTIN 22) SIGTTOU 23) SIGURG  24) SIGXCPU
25) SIGXFSZ 26) SIGVTALRM   27) SIGPROF 28) SIGWINCH
29) SIGIO   30) SIGPWR  31) SIGSYS  34) SIGRTMIN
35) SIGRTMIN+1  36) SIGRTMIN+2  37) SIGRTMIN+3  38) SIGRTMIN+4
39) SIGRTMIN+5  40) SIGRTMIN+6  41) SIGRTMIN+7  42) SIGRTMIN+8
43) SIGRTMIN+9  44) SIGRTMIN+10 45) SIGRTMIN+11 46) SIGRTMIN+12
47) SIGRTMIN+13 48) SIGRTMIN+14 49) SIGRTMIN+15 50) SIGRTMAX-14
51) SIGRTMAX-13 52) SIGRTMAX-12 53) SIGRTMAX-11 54) SIGRTMAX-10
55) SIGRTMAX-9  56) SIGRTMAX-8  57) SIGRTMAX-7  58) SIGRTMAX-6
59) SIGRTMAX-5  60) SIGRTMAX-4  61) SIGRTMAX-3  62) SIGRTMAX-2
63) SIGRTMAX-1  64) SIGRTMAX    

You can determine the sender by using an appropriate signal handler like:

#include <signal.h>
#include <stdio.h>
#include <stdlib.h>

void sigterm_handler(int signal, siginfo_t *info, void *_unused)
{
  fprintf(stderr, "Received SIGTERM from process with pid = %u\n",
      info->si_pid);
  exit(0);
}

int main (void)
{
  struct sigaction action = {
    .sa_handler = NULL,
    .sa_sigaction = sigterm_handler,
    .sa_mask = 0,
    .sa_flags = SA_SIGINFO,
    .sa_restorer = NULL
  };

  sigaction(SIGTERM, &action, NULL);
  sleep(60);

  return 0;
}

Notice that the signal handler also includes a call to exit(). It's also possible for your program to continue to execute by ignoring the signal, but this isn't recommended in general (if it's a user doing it there's a good chance it will be followed by a SIGKILL if your process doesn't exit, and you lost your opportunity to do any cleanup then).

I usually prefer to work with deltas in translate animation, since it avoids a lot of confusion.

Try this out, see if it works for you:

TranslateAnimation anim = new TranslateAnimation(0, amountToMoveRight, 0, amountToMoveDown);
anim.setDuration(1000);

anim.setAnimationListener(new TranslateAnimation.AnimationListener() {

This is not exactly the answer to the question, but I end up here every time I want to find out how to get my batch file to exit with and error code when a process returns an nonzero code.

So here is the answer to that:

Font Squirrel has a wonderful web font generator.

I think you should find what you need here to generate OTF fonts and the needed CSS to use them. It will even support older IE versions.

I found another set of examples for customizing an AlertDialog from a guy named Mossila. I think they're better than Google's examples. To quickly see Google's API demos, you must import their demo jar(s) into your project, which you probably don't want.

But Mossila's example code is fully self-contained. It can be directly cut-and-pasted into your project. It just works! Then you only need to tweak it to your needs. See here

To keep the color and prevent an underline on the link:

legend.green-color a{
    color:green;
    text-decoration: none;
}

You could get first rows of Spark DataFrame with head and then create Pandas DataFrame:

l = [('Alice', 1),('Jim',2),('Sandra',3)]
df = sqlContext.createDataFrame(l, ['name', 'age'])

df_pandas = pd.DataFrame(df.head(3), columns=df.columns)

In [4]: df_pandas
Out[4]: 
     name  age
0   Alice    1
1     Jim    2
2  Sandra    3

Yes, you can edit the iPad hosts file, but you need to be jailbroken. Once you've done that, download Cydia (app market), and get iFile. The hosts file is located within "/etc/hosts".

When using System.Net.WebRequest your application will negotiate with the server to determine the highest TLS version that both your application and the server support, and use this. You can see more details on how this works here:

http://en.wikipedia.org/wiki/Transport_Layer_Security#TLS_handshake

If the server doesn't support TLS it will fallback to SSL, therefore it could potentially fallback to SSL3. You can see all of the versions that .NET 4.5 supports here:

http://msdn.microsoft.com/en-us/library/system.security.authentication.sslprotocols(v=vs.110).aspx

In order to prevent your application being vulnerable to POODLE, you can disable SSL3 on the machine that your application is running on by following this explanation:

https://serverfault.com/questions/637207/on-iis-how-do-i-patch-the-ssl-3-0-poodle-vulnerability-cve-2014-3566

Just to add some more empirical info, I have been investigating the whole issue of upgradable locks, and Example for boost shared_mutex (multiple reads/one write)? is a good answer adding the important info that only one thread can have an upgrade_lock even if it is not upgraded, that is important as it means you cannot upgrade from a shared lock to a unique lock without releasing the shared lock first. (This has been discussed elsewhere but the most interesting thread is here http://thread.gmane.org/gmane.comp.lib.boost.devel/214394)

However I did find an important (undocumented) difference between a thread waiting for an upgrade to a lock (ie needs to wait for all readers to release the shared lock) and a writer lock waiting for the same thing (ie a unique_lock).

1. The thread that is waiting for a unique_lock on the shared_mutex blocks any new readers coming in, they have to wait for the writers request. This ensures readers do not starve writers (however I believe writers could starve readers).

2. The thread that is waiting for an upgradeable_lock to upgrade allows other threads to get a shared lock, so this thread could be starved if readers are very frequent.

This is an important issue to consider, and probably should be documented.

I'm not certain why everyone is claiming that you need a using statement at the top of your file, as this is entirely unnecessary.

Right-click on the "References" folder in your project and select "Add Reference". If your new class library is a project in the same solution, select the "Project" tab and pick the project. If the new library is NOT in the same solution, click the "Browse" tab and find the .dll for your new project.

Something like...

DateTime today = new DateTime();
DateTime yesterday = today.minusDays(1);

Duration duration = new Duration(yesterday, today);
System.out.println(duration.getStandardDays());
System.out.println(duration.getStandardHours());
System.out.println(duration.getStandardMinutes());

Which outputs

1
24
1440

or

System.out.println(Minutes.minutesBetween(yesterday, today).getMinutes());

Which is probably more what you're after

Array has no indexOf() method.

Maybe this Apache Commons Lang ArrayUtils method is what you are looking for

import org.apache.commons.lang3.ArrayUtils;

String[] colours = { "Red", "Orange", "Yellow", "Green" };

int indexOfYellow = ArrayUtils.indexOf(colours, "Yellow");

You need to declare @font-face like this in your stylesheet

@font-face {
  font-family: 'Awesome-Font';
  font-style: normal;
  font-weight: 400;
  src: local('Awesome-Font'), local('Awesome-Font-Regular'), url(path/Awesome-Font.woff) format('woff');
}

Now if you want to apply this font to a paragraph simply use it like this..

p {
font-family: 'Awesome-Font', Arial;
}

Circular dependency in Spring : Dependency of one Bean to other. Bean A ? Bean B ? Bean A

Solutions:

1. Use @Lazy Annotation
2. Redesign you class dependency
3. Use Setter/Field Injection
4. Use @PostConstruct Annotation

I found the answer is git reset --merge - it clears the conflicted cherry-pick attempt.

I would argue you might want to use a cursor when you want to do comparisons of characteristics that are on different rows of the return set, or if you want to write a different output row format than a standard one in certain cases. Two examples come to mind:

1. One was in a college where each add and drop of a class had its own row in the table. It might have been bad design but you needed to compare across rows to know how many add and drop rows you had in order to determine whether the person was in the class or not. I can't think of a straight forward way to do that with only sql.

2. Another example is writing a journal total line for GL journals. You get an arbitrary number of debits and credits in your journal, you have many journals in your rowset return, and you want to write a journal total line every time you finish a journal to post it into a General Ledger. With a cursor you could tell when you left one journal and started another and have accumulators for your debits and credits and write a journal total line (or table insert) that was different than the debit/credit line.

Changing text color of button

Because this method is now deprecated

button.setTextColor(getResources().getColor(R.color.your_color));

I use the following:

button.setTextColor(ContextCompat.getColor(mContext, R.color.your_color));

Try this:

df.loc[len(df)]=['8/19/2014','Jun','Fly','98765'] 

Warning: this method works only if there are no "holes" in the index. For example, suppose you have a dataframe with three rows, with indices 0, 1, and 3 (for example, because you deleted row number 2). Then, len(df) = 3, so by the above command does not add a new row - it overrides row number 3.

You can also use IFNA(expression, value)

Try using this code for v3:

gMap = new google.maps.Map(document.getElementById('map')); 
gMap.setZoom(13);      // This will trigger a zoom_changed on the map
gMap.setCenter(new google.maps.LatLng(37.4419, -122.1419));
gMap.setMapTypeId(google.maps.MapTypeId.ROADMAP);

You need to precede the lines starting with gcc and rm with a hard tab. Commands in make rules are required to start with a tab (unless they follow a semicolon on the same line). The result should look like this:

PROG = semsearch
all: $(PROG)
%: %.c
        gcc -o $@ $< -lpthread

clean:
        rm $(PROG)

Note that some editors may be configured to insert a sequence of spaces instead of a hard tab. If there are spaces at the start of these lines you'll also see the "missing separator" error. If you do have problems inserting hard tabs, use the semicolon way:

PROG = semsearch
all: $(PROG)
%: %.c ; gcc -o $@ $< -lpthread

clean: ; rm $(PROG)

I found a jfiddle that might help here: http://jsfiddle.net/jaredwilli/SfJ8c/

Ive refactored the code to make it simpler for this.

// In your controller
var w = angular.element($window);
$scope.$watch(
  function () {
    return $window.innerWidth;
  },
  function (value) {
    $scope.windowWidth = value;
  },
  true
);

w.bind('resize', function(){
  $scope.$apply();
});

You can then reference to windowWidth from the html

<span ng-bind="windowWidth"></span>

Try this:

SELECT Count(*)
FROM <DATABASE_NAME>.INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'

• XHR polling A Request is answered when the event occurs (could be straight away, or after a delay). Subsequent requests will need to made to receive further events.

  The browser makes an asynchronous request of the server, which may wait for data to be available before responding. The response can contain encoded data (typically XML or JSON) or Javascript to be executed by the client. At the end of the processing of the response, the browser creates and sends another XHR, to await the next event. Thus the browser always keeps a request outstanding with the server, to be answered as each event occurs. Wikipedia

• Server Sent Events Client sends request to server. Server sends new data to webpage at any time.

  Traditionally, a web page has to send a request to the server to receive new data; that is, the page requests data from the server. With server-sent events, it's possible for a server to send new data to a web page at any time, by pushing messages to the web page. These incoming messages can be treated as Events + data inside the web page. Mozilla

• WebSockets After the initial handshake (via HTTP protocol). Communication is done bidirectionally using the WebSocket protocol.

  The handshake starts with an HTTP request/response, allowing servers to handle HTTP connections as well as WebSocket connections on the same port. Once the connection is established, communication switches to a bidirectional binary protocol which does not conform to the HTTP protocol. Wikipedia

It makes a duplicate copy of the string passed in by running a malloc and strcpy of the string passed in. The malloc'ed buffer is returned to the caller, hence the need to run free on the return value.

Try this:

string employeeName = chldNode.Attributes["Name"].Value;

Edit: As pointed out in the comments, this will throw an exception if the attribute doesn't exist. The safe way is:

var attribute = node.Attributes["Name"];
if (attribute != null){
    string employeeName = attribute.Value;
    // Process the value here
}

Template/HTML File (component.ts)

    console.log(cityEvent); // It will display the select city data

(ngModelChange) is the @Output of the ngModel directive. It fires when the model changes. You cannot use this event without the ngModel directive

All other answers, and mainly about list comprehension, are great. But just to explain your error:

strip_list = []
for lengths in range(1,20):
    strip_list.append(0) #longest word in the text file is 20 characters long
for a in lines:
    strip_list.append(lines[a].strip())

a is a member of your list, not an index. What you could write is this:

[...]
for a in lines:
    strip_list.append(a.strip())

Another important comment: you can create an empty list this way:

strip_list = [0] * 20

But this is not so useful, as .append appends stuff to your list. In your case, it's not useful to create a list with defaut values, as you'll build it item per item when appending stripped strings.

So your code should be like:

strip_list = []
for a in lines:
    strip_list.append(a.strip())

But, for sure, the best one is this one, as this is exactly the same thing:

stripped = [line.strip() for line in lines]

In case you have something more complicated than just a .strip, put this in a function, and do the same. That's the most readable way to work with lists.

Using find:

find . -maxdepth 1 -type f

Using the -maxdepth 1 option ensures that you only look in the current directory (or, if you replace the . with some path, that directory). If you want a full recursive listing of all files in that and subdirectories, just remove that option.

You try the following ways to run the multiple python scripts:

  import os
  print "Starting script1"
  os.system("python script1.py arg1 arg2 arg3")
  print "script1 ended"
  print "Starting script2"
  os.system("python script2.py arg1 arg2 arg3")
  print "script2 ended"

Note: The execution of multiple scripts depends purely underlined operating system, and it won't be concurrent, I was new comer in Python when I answered it.

Update: I found a package: https://pypi.org/project/schedule/ Above package can be used to run multiple scripts and function, please check this and maybe on weekend will provide some example too.

i.e:

 import schedule
 import time
 import script1, script2

 def job():
     print("I'm working...")

 schedule.every(10).minutes.do(job)
 schedule.every().hour.do(job)
 schedule.every().day.at("10:30").do(job)
 schedule.every(5).to(10).days.do(job)
 schedule.every().monday.do(job)
 schedule.every().wednesday.at("13:15").do(job)

 while True:
     schedule.run_pending()
     time.sleep(1)

There is a Free tool named binarydoc which can generate UML Sequence Diagram, or Control Flow Graph (CFG) from the bytecode (instead of source code) of a Java method.

You can do something like this:

File file = new File("Student.txt");

try {
    Scanner scanner = new Scanner(file);

    //now read the file line by line...
    int lineNum = 0;
    while (scanner.hasNextLine()) {
        String line = scanner.nextLine();
        lineNum++;
        if(<some condition is met for the line>) { 
            System.out.println("ho hum, i found it on line " +lineNum);
        }
    }
} catch(FileNotFoundException e) { 
    //handle this
}

Using display:none is not SEO-friendly. The following way allows the hidden content to be searchable. Adding the transition-delay ensures any links included in the hidden content is clickable.

.collapse > p{
cursor: pointer;
display: block;
}

.collapse:focus{
outline: none;
}

.collapse > div {
height: 0;
width: 0;
overflow: hidden;
transition-delay: 0.3s;
}

.collapse:focus div{
display: block; 
height: 100%;
width: 100%;
overflow: auto;
}

<div class="collapse" tabindex="1">
<p>Question 1</p>
<div>
  <p>Visit <a href="https://stackoverflow.com/">Stack Overflow</a></p>
</div>
</div>
<div class="collapse" tabindex="2">

In my case, I passed an async lambda to Console.CancelKeyPress, which won't work.

Dictionary is the most common, but you can use other types of collections, e.g. System.Collections.Generic.SynchronizedKeyedCollection, System.Collections.Hashtable, or any KeyValuePair collection

I think there's a simpler solution: Just use the DialogInterface argument that is passed to the onClick method.

AlertDialog.Builder db = new AlertDialog.Builder(context);
        db.setNegativeButton("cancel", new DialogInterface.OnClickListener(){
            @Override
            public void onClick(DialogInterface d, int arg1) {
                db.cancel();
                //here db.cancel will dismiss the builder

            };  
        });

See, for example, http://www.mkyong.com/android/android-alert-dialog-example.

I think you're a little confused. PYTHONPATH sets the search path for importing python modules, not for executing them like you're trying.

PYTHONPATH Augment the default search path for module files. The format is the same as the shell’s PATH: one or more directory pathnames separated by os.pathsep (e.g. colons on Unix or semicolons on Windows). Non-existent directories are silently ignored.

In addition to normal directories, individual PYTHONPATH entries may refer to zipfiles containing pure Python modules (in either source or compiled form). Extension modules cannot be imported from zipfiles.

The default search path is installation dependent, but generally begins with prefix/lib/pythonversion (see PYTHONHOME above). It is always appended to PYTHONPATH.

An additional directory will be inserted in the search path in front of PYTHONPATH as described above under Interface options. The search path can be manipulated from within a Python program as the variable sys.path.

http://docs.python.org/2/using/cmdline.html#envvar-PYTHONPATH

What you're looking for is PATH.

export PATH=$PATH:/home/randy/lib/python 

However, to run your python script as a program, you also need to set a shebang for Python in the first line. Something like this should work:

#!/usr/bin/env python

And give execution privileges to it:

chmod +x /home/randy/lib/python/gbmx.py

Then you should be able to simply run gmbx.py from anywhere.

Following on from @Ryan Reich's answer, I thought I'd offer my cleaned up version. The first bounds check isn't required given the second bounds check, and I've made it iterative rather than recursive. It returns values in the range [min, max], where max >= min and 1+max-min < RAND_MAX.

unsigned int rand_interval(unsigned int min, unsigned int max)
{
    int r;
    const unsigned int range = 1 + max - min;
    const unsigned int buckets = RAND_MAX / range;
    const unsigned int limit = buckets * range;

    /* Create equal size buckets all in a row, then fire randomly towards
     * the buckets until you land in one of them. All buckets are equally
     * likely. If you land off the end of the line of buckets, try again. */
    do
    {
        r = rand();
    } while (r >= limit);

    return min + (r / buckets);
}

I solved this issue following the indication provided in the article http://blog.dev-area.net/2015/08/13/android-4-1-enable-tls-1-1-and-tls-1-2/ with little changes.

SSLContext context = SSLContext.getInstance("TLS");
context.init(null, null, null);
SSLSocketFactory noSSLv3Factory = null;
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT) {
    noSSLv3Factory = new TLSSocketFactory(sslContext.getSocketFactory());
} else {
    noSSLv3Factory = sslContext.getSocketFactory();
}
connection.setSSLSocketFactory(noSSLv3Factory);

This is the code of the custom TLSSocketFactory:

public static class TLSSocketFactory extends SSLSocketFactory {

    private SSLSocketFactory internalSSLSocketFactory;

    public TLSSocketFactory(SSLSocketFactory delegate) throws KeyManagementException, NoSuchAlgorithmException {
        internalSSLSocketFactory = delegate;
    }

    @Override
    public String[] getDefaultCipherSuites() {
        return internalSSLSocketFactory.getDefaultCipherSuites();
    }

    @Override
    public String[] getSupportedCipherSuites() {
        return internalSSLSocketFactory.getSupportedCipherSuites();
    }

    @Override
    public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose));
    }

        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
    }

    @Override
    public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
        return enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort));
    }

    /*

     */

    private static Socket enableTLSOnSocket(Socket socket) {
        if (socket != null && (socket instanceof SSLSocket)
                && isTLSServerEnabled((SSLSocket) socket)) { // skip the fix if server doesn't provide there TLS version
            ((SSLSocket) socket).setEnabledProtocols(new String[]{TLS_v1_1, TLS_v1_2});
        }
        return socket;
    }

    private static boolean isTLSServerEnabled(SSLSocket sslSocket) {
        System.out.println("__prova__ :: " + sslSocket.getSupportedProtocols().toString());
        for (String protocol : sslSocket.getSupportedProtocols()) {
            if (protocol.equals(TLS_v1_1) || protocol.equals(TLS_v1_2)) {
                return true;
            }
        }
        return false;
    }
}

To get the current router instance or current location you have to create a Higher order component with withRouter from react-router-dom. otherwise, when you are trying to access this.props.location it will return undefined

Example

import React, { Component } from 'react';
import { withRouter } from 'react-router-dom';

class className extends Component {

      render(){
           return(
                ....
                  )
              }
}

export default withRouter(className)

my quickest solution was to minus 1 to the length of the array as

  $len = count($data);

    for($i=1; $i<=$len-1;$i++){
      echo $data[$i];
    }

my offset was always the last value if the count was 140 then it will say offset 140 but after using the minus 1 everything was fine

I would "inject" the starttime variable instead, otherwise you have a circular dependency between the packages.

main.go

var StartTime = time.Now()
func main() {
   otherPackage.StartTime = StartTime
}

otherpackage.go

var StartTime time.Time

The top ranked answer to this question suggests using the readLine() method to take in user input from the command line. However, I want to note that you need to use the ! operator when calling this method to return a string instead of an optional:

var response = readLine()!

As stated in other answers, the simplest method is to uniquely identify the root element (by ID or class name) and use the direct descendent selector.

$('ul.topMenu > li > a')

However, I came across this question in search of a solution which would work on unnamed elements at varying depths of the DOM.

This can be achieved by checking each element, and ensuring it does not have a parent in the list of matched elements. Here is my solution, wrapped in a jQuery selector 'topmost'.

jQuery.extend(jQuery.expr[':'], {
  topmost: function (e, index, match, array) {
    for (var i = 0; i < array.length; i++) {
      if (array[i] !== false && $(e).parents().index(array[i]) >= 0) {
        return false;
      }
    }
    return true;
  }
});

Utilizing this, the solution to the original post is:

$('ul:topmost > li > a')

// Or, more simply:
$('li:topmost > a')

Complete jsFiddle available here.

You can use

df <- read.csv("filename.csv", header=TRUE)

# To loop each column
for (i in 1:ncol(df))
    {
    dosomething(df[,i])
    }
# To loop each row
for (i in 1:nrow(df))
    {
    dosomething(df[i,])
    }

Also, you may want to have a look to the apply function (type ?apply or help(apply))if you want to use the same function on each row/column
