You can set it as a no title bar theme in the activity's xml in the AndroidManifest

    <activity 
        android:name=".AnActivity"
        android:label="@string/a_string"
        android:theme="@android:style/Theme.NoTitleBar">
    </activity>

Another way:

x=$'Some\nstring'
readarray -t y <<<"$x"

Or, if you don't have bash 4, the bash 3.2 equivalent:

IFS=$'\n' read -rd '' -a y <<<"$x"

You can also do it the way you were initially trying to use:

y=(${x//$'\n'/ })

This, however, will not function correctly if your string already contains spaces, such as 'line 1\nline 2'. To make it work, you need to restrict the word separator before parsing it:

IFS=$'\n' y=(${x//$'\n'/ })

...and then, since you are changing the separator, you don't need to convert the \n to space anymore, so you can simplify it to:

IFS=$'\n' y=($x)

This approach will function unless $x contains a matching globbing pattern (such as "*") - in which case it will be replaced by the matched file name(s). The read/readarray methods require newer bash versions, but work in all cases.

I wrote this a long time ago (from years 1985-1992, with just a few tweaks since then), and just copy and paste the bits needed into each project.

You must call cfmakeraw on a tty obtained from tcgetattr. You cannot zero-out a struct termios, configure it, and then set the tty with tcsetattr. If you use the zero-out method, then you will experience unexplained intermittent failures, especially on the BSDs and OS X. "Unexplained intermittent failures" include hanging in read(3).

The values for speed are B115200, B230400, B9600, B19200, B38400, B57600, B1200, B2400, B4800, etc. The values for parity are 0 (meaning no parity), PARENB|PARODD (enable parity and use odd), PARENB (enable parity and use even), PARENB|PARODD|CMSPAR (mark parity), and PARENB|CMSPAR (space parity).

"Blocking" sets whether a read() on the port waits for the specified number of characters to arrive. Setting no blocking means that a read() returns however many characters are available without waiting for more, up to the buffer limit.

Addendum:

CMSPAR is needed only for choosing mark and space parity, which is uncommon. For most applications, it can be omitted. My header file /usr/include/bits/termios.h enables definition of CMSPAR only if the preprocessor symbol __USE_MISC is defined. That definition occurs (in features.h) with

#if defined _BSD_SOURCE || defined _SVID_SOURCE
 #define __USE_MISC     1
#endif

The introductory comments of <features.h> says:

/* These are defined by the user (or the compiler)
   to specify the desired environment:

...
   _BSD_SOURCE          ISO C, POSIX, and 4.3BSD things.
   _SVID_SOURCE         ISO C, POSIX, and SVID things.

Just add createDatabaseIfNotExist=true parameter in spring datasource url

Example: spring.datasource.url= jdbc:mysql://localhost:3306/test?createDatabaseIfNotExist=true

You can still use angular.isDefined()

You just need to set

$rootScope.angular = angular;

in the "run" phase.

See update plunkr: http://plnkr.co/edit/h4ET5dJt3e12MUAXy1mS?p=preview

In some environments, NSLog() will be unresponsive. But there are other ways to get output...

NSString* url = @"someurlstring";
printf("%s", [url UTF8String]);

By using printf with the appropriate parameters, we can display things this way. This is the only way I have found to work on online Objective-C sandbox environments.

When the return key is pressed, call:

[uitextfield resignFirstResponder];

This displays the name of the current user:

Function Username() As String
    Username = Application.Username
End Function

The property Application.Username holds the name entered with the installation of MS Office.

Enter this formula in a cell:

=Username()

max(files, key = os.path.getctime)

is quite incomplete code. What is files? It probably is a list of file names, coming out of os.listdir().

But this list lists only the filename parts (a. k. a. "basenames"), because their path is common. In order to use it correctly, you have to combine it with the path leading to it (and used to obtain it).

Such as (untested):

def newest(path):
    files = os.listdir(path)
    paths = [os.path.join(path, basename) for basename in files]
    return max(paths, key=os.path.getctime)

To remove specific key and element from hashmap use

hashmap.remove(key)

full source code is like

import java.util.HashMap;
public class RemoveMapping {
     public static void main(String a[]){
        HashMap hashMap = new HashMap();
        hashMap.put(1, "One");
        hashMap.put(2, "Two");
        hashMap.put(3, "Three");
        System.out.println("Original HashMap : "+hashMap);
        hashMap.remove(3);   
        System.out.println("Changed HashMap : "+hashMap);        
    }
}

Seems to me like you want to create a property.

public int MyProperty
{
    get { return _myProperty; }
    set
    {
        _myProperty = value;
        if (_myProperty == 1)
        {
            // DO SOMETHING HERE
        }
    }
}

private int _myProperty;

This allows you to run some code any time the property value changes. You could raise an event here, if you wanted.

You must make your binding bidirectional :

<checkbox IsChecked="{Binding Path=MyProperty, Mode=TwoWay}"/>

we don't need base64 , just give your image path and dimensions as shown below.

import Logo from './Logo.png' //local path

        var doc=new jsPDF("p", "mm", "a4");
        var img = new Image();
        img.src =Logo;
        doc.addImage(img, 'png', 10, 78, 12, 15)

Just in case you ever want to do this not on Android it's helpful to think about which day where as not all devices mark their calendar in local time.

From Java 8 onwards:

LocalDate.now(ZoneId.of("America/Detroit")).getDayOfWeek()

SELECT *
FROM   tbl
WHERE  id = 1
ORDER  BY signin DESC
LIMIT  1;

The obvious index would be on (id), or a multicolumn index on (id, signin DESC).

Conveniently for the case, MySQL sorts NULL values last in descending order. That's what you typically want if there can be NULL values: the row with the latest not-null signin.

To get NULL values first:

ORDER BY signin IS NOT NULL, signin DESC

You may want to append more expressions to ORDER BY to get a deterministic pick from (potentially) multiple rows with NULL.
The same applies without NULL if signin is not defined UNIQUE.

Related:

• mysql order by, null first, and DESC after

The SQL standard does not explicitly define a default sort order for NULL values. The behavior varies quite a bit across different RDBMS. See:

• https://docs.mendix.com/refguide/null-ordering-behavior

But there are the NULLS FIRST / NULLS LAST clauses defined in the SQL standard and supported by most major RDBMS, but not by MySQL. See:

• SQL how to make null values come last when sorting ascending
• Sort by column ASC, but NULL values first?

In case anyone had the same problem: check this as @PravinS suggested. I used the exact same code as shown there and it worked for me perfectly.

This is the relevant part of the server code that helped:

if (isset($_POST['btnUpload']))
{
$url = "URL_PATH of upload.php"; // e.g. http://localhost/myuploader/upload.php // request URL
$filename = $_FILES['file']['name'];
$filedata = $_FILES['file']['tmp_name'];
$filesize = $_FILES['file']['size'];
if ($filedata != '')
{
    $headers = array("Content-Type:multipart/form-data"); // cURL headers for file uploading
    $postfields = array("filedata" => "@$filedata", "filename" => $filename);
    $ch = curl_init();
    $options = array(
        CURLOPT_URL => $url,
        CURLOPT_HEADER => true,
        CURLOPT_POST => 1,
        CURLOPT_HTTPHEADER => $headers,
        CURLOPT_POSTFIELDS => $postfields,
        CURLOPT_INFILESIZE => $filesize,
        CURLOPT_RETURNTRANSFER => true
    ); // cURL options
    curl_setopt_array($ch, $options);
    curl_exec($ch);
    if(!curl_errno($ch))
    {
        $info = curl_getinfo($ch);
        if ($info['http_code'] == 200)
            $errmsg = "File uploaded successfully";
    }
    else
    {
        $errmsg = curl_error($ch);
    }
    curl_close($ch);
}
else
{
    $errmsg = "Please select the file";
}
}

html form should look something like:

<form action="uploadpost.php" method="post" name="frmUpload" enctype="multipart/form-data">
<tr>
  <td>Upload</td>
  <td align="center">:</td>
  <td><input name="file" type="file" id="file"/></td>
</tr>
<tr>
  <td>&nbsp;</td>
  <td align="center">&nbsp;</td>
  <td><input name="btnUpload" type="submit" value="Upload" /></td>
</tr>

Got this from Bing. Seems Microsoft has removed some features from the core framework and added it to a separate optional(?) framework component.

To quote from MSDN (http://msdn.microsoft.com/en-us/library/cc656912.aspx)

The .NET Framework 4 Client Profile does not include the following features. You must install the .NET Framework 4 to use these features in your application:

* ASP.NET
* Advanced Windows Communication Foundation (WCF) functionality
* .NET Framework Data Provider for Oracle
* MSBuild for compiling

I am answering this for the benefit of future community users. There were multiple issues. If you encounter this problem, I suggest you look for the following:

• Make sure your tnsnames.ora is complete and has the databases you wish to connect to
• Make sure you can tnsping the server you wish to connect to
• On the server, make sure it will be open on the port you desire with the specific application you are using.

Once I did these three things, I solved my problem.

Try macincloud.com It allows you to rent a mac and access it through RDP remote control. You can then use your PC to access a mac and then develop your apps.

First of all, from __future__ import print_function needs to be the first line of code in your script (aside from some exceptions mentioned below). Second of all, as other answers have said, you have to use print as a function now. That's the whole point of from __future__ import print_function; to bring the print function from Python 3 into Python 2.6+.

from __future__ import print_function

import sys, os, time

for x in range(0,10):
    print(x, sep=' ', end='')  # No need for sep here, but okay :)
    time.sleep(1)

__future__ statements need to be near the top of the file because they change fundamental things about the language, and so the compiler needs to know about them from the beginning. From the documentation:

A future statement is recognized and treated specially at compile time: Changes to the semantics of core constructs are often implemented by generating different code. It may even be the case that a new feature introduces new incompatible syntax (such as a new reserved word), in which case the compiler may need to parse the module differently. Such decisions cannot be pushed off until runtime.

The documentation also mentions that the only things that can precede a __future__ statement are the module docstring, comments, blank lines, and other future statements.

If you are using ajax, you may want to get updated value of select right after the selection.

//Part 1

$(".element").select2(/*Your code*/)    

//Part 2 - continued 

$(".element").on("select2:select", function (e) { 
  var select_val = $(e.currentTarget).val();
  console.log(select_val)
});

For reference, these are very similar questions.

These seem to work the best for me. They also work with spaces, and don't re-add ignored files. I didn't see them listed on any of the other answers I saw.

adding:

svn st | grep ^? | sed 's/?    //' | xargs svn add

removing:

svn st | grep ^! | sed 's/!    //' | xargs svn rm

Edit: It's important to NOT use "add *" if you want to keep your ignored files, otherwise everything that was ignored will be re-added.

I am not an expert in HTML but here is what worked for me:

<div class="img-with-text-below">
    <img src="your-image.jpg" alt="alt-text" />
    <p><center>Your text</center></p>
</div>

You could also display a progress bar or a spinner to indicate that the form is processing.

When you assign a function to a variable you don't use the () but simply the name of the function.

In your case given def x(): ..., and variable silly_var you would do something like this:

silly_var = x

and then you can call the function either with

x()

or

silly_var()

It depends on which language you use.

In Java/Java EE:

• Jetty 7.0 supports it (very easy to use) V 7.5 supports RFC6455 - Jetty 9.1 supports javax.websocket / JSR 356)
• GlassFish 3.0 (very low level and sometimes complex), Glassfish 3.1 has new refactored Websocket Support which is more developer friendly V 3.1.2 supports RFC6455
• Caucho Resin 4.0.2 (not yet tried) V 4.0.25 supports RFC6455
• Tomcat 7.0.27 now supports it V 7.0.28 supports RFC6455
• Tomcat 8.x has native support for websockets RFC6455 and is JSR 356 compliant
• JSR 356 included in Java EE 7 will define the Java API for WebSocket, but is not yet stable and complete.

The best tool for doing layouts using grid, IMHO, is graph paper and a pencil. I know you're asking for some type of program, but it really does work. I've been doing Tk programming for a couple of decades so layout comes quite easily for me, yet I still break out graph paper when I have a complex GUI.

Another thing to think about is this: The real power of Tkinter geometry managers comes from using them together*. If you set out to use only grid, or only pack, you're doing it wrong. Instead, design your GUI on paper first, then look for patterns that are best solved by one or the other. Pack is the right choice for certain types of layouts, and grid is the right choice for others. For a very small set of problems, place is the right choice. Don't limit your thinking to using only one of the geometry managers.

* The only caveat to using both geometry managers is that you should only use one per container (a container can be any widget, but typically it will be a frame).

You're not running a module -- you're running subroutines/functions that happen to be stored in modules.

If you put the code in a standalone module and don't specify scope in the definitions of your subroutines/functions, they will be public by default, and callable from anywhere within your application. This means that you can call them with RunCode in a macro, from the class modules of forms/reports, from standalone class modules, or for the functions, from SQL (with some caveats).

Given that you were trying to implement in VBA something that you felt was too complicated for SQL, SQL is the likely context in which you want to execute the code. So, you should just be able to call your function within the SQL statement:

  SELECT MyTable.PersonID, MyTable.FirstName, MyTable.LastName, FormatAddress([Address], [City], [State], [Zip], [Country]) As Address
  FROM MyTable;

That SQL calls a public function called FormatAddress() that takes as arguments the components of an address and formats them appropriately. It's a trivial example as you likely would not need a VBA function for that purpose, but the point is that this is how you call functions from within a SQL statement.

Subroutines (i.e., code that returns no value) are not callable from within SQL statements.

Whenever you have to perform some action on the click of the Spinner in Android, use the following method.

mspUserState.setOnTouchListener(new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) {
            doWhatIsRequired();
        }
        return false;
    }
});

One thing to keep in mind is always to return False while using the above method. If you will return True then the dropdown items of the spinner will not be displayed on clicking the Spinner.

On Windows, line.separator is a CR/LF combination (reference here).

The Java String.split() method takes a regular expression. So I think there's some confusion here.

If you have web.xml then

HTML/JSP

<form action="${pageContext.request.contextPath}/myservlet" method="post">
    <input type="submit" name="button1" value="Button 1" />
</form>

web.xml

<servlet>
        <display-name>Servlet Name</display-name>
        <servlet-name>myservlet</servlet-name>
        <servlet-class>package.SomeController</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>myservlet</servlet-name>
    <url-pattern>/myservlet</url-pattern>
</servlet-mapping>

Java SomeController.java

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        System.out.println("Write your code below");
}

Be careful with the main answer.

with

[['id'=>1,'cat'=>'vip']
,['id'=>2,'cat'=>'vip']
,['id'=>3,'cat'=>'normal']

and calling the function

foreach($array as $elementKey => $element) {
    foreach($element as $valueKey => $value) {
        if($valueKey == 'cat' && $value == 'vip'){
            //delete this particular object from the $array
            unset($array[$elementKey]);
        } 
    }
}

it returns

[2=>['id'=>3,'cat'=>'normal']

instead of

[0=>['id'=>3,'cat'=>'normal']

It is because unset does not re-index the array.

It reindexes. (if we need it)

$result=[];
foreach($array as $elementKey => $element) {
    foreach($element as $valueKey => $value) {
        $found=false;
        if($valueKey === 'cat' && $value === 'vip'){
            $found=true;
            $break;
        } 
        if(!$found) {
           $result[]=$element;
        }
    }
}

Change maxDate to current date

maxDate: new Date()

It will set current date as maximum value.

In windows 7, 8, and 10 you can find at the following location

Check out the static java.util.Arrays.equals() family of methods. There's one that does exactly what you want.

put string first

Intent secondIntent = new Intent(this, typeof(SecondActivity));
            secondIntent.PutExtra("message", "Greetings from MainActivity");

retrieve it after that

var message = this.Intent.GetStringExtra("message");

thats All ;)

After reading the answer from Gilles, I decided to see if the $BASH_COMMAND var was also available (and the desired value) in an EXIT trap - and it is!

So, the following bash script works as expected:

#!/bin/bash

exit_trap () {
  local lc="$BASH_COMMAND" rc=$?
  echo "Command [$lc] exited with code [$rc]"
}

trap exit_trap EXIT
set -e

echo "foo"
false 12345
echo "bar"

The output is

foo
Command [false 12345] exited with code [1]

bar is never printed because set -e causes bash to exit the script when a command fails and the false command always fails (by definition). The 12345 passed to false is just there to show that the arguments to the failed command are captured as well (the false command ignores any arguments passed to it)

The other answers show you to create the polygons, but not how to get the coordinates...

I'm not sure the best way to do it, but heres one way.. It seems like there should be a method to get the paths from the polygon, but I can't find one, and getPath() doesn't seem to work for me. So here's a manual approach that worked for me..

Once you've finished drawing your polygon, and pass in your polygon to the overlay complete function, you can find the coordinates in the polygon.overlay.latLngs.b[0].b

google.maps.event.addListener(drawingManager, 'overlaycomplete', function(polygon) {
        $.each(polygon.overlay.latLngs.b[0].b, function(key, latlng){
            var lat = latlng.d;
            var lon = latlng.e;
            console.log(lat, lon); //do something with the coordinates
        });
});

note, i'm using jquery to loop over the list of coordinates, but you can do loop however.

Use Jenkins CLI like this:

java -jar jenkins-cli.jar -s http://[jenkins_server] groovy = < pluginEnumerator.groovy

= in the call means 'read from standard input'. pluginEnumerator.groovy contains the following Groovy code:

println "Running plugin enumerator"
println ""
def plugins = jenkins.model.Jenkins.instance.getPluginManager().getPlugins()
plugins.each {println "${it.getShortName()} - ${it.getVersion()}"}
println ""
println "Total number of plugins: ${plugins.size()}"

If you would like to play with the code, here's Jenkins Java API documentation.

Here is an illustration of your first import cycle problem.

                  project/controllers/account
                     ^                    \    
                    /                      \
                   /                        \ 
                  /                         \/
         project/components/mux <--- project/controllers/base

As you can see with my bad ASCII chart is that you are creating an import cycle when project/components/mux imports project/controllers/account. Since Go does not support circular dependencies you get the import cycle not allowed error during compile time.

Yes, to some degree as detailed here.
The approach I've used (pre-2008) is to do the conversion in the .NET business logic before inserting into the DB.

Also, in your html, remember to delete all blanks / line feeds / tabs between the closing tag and the opening tag.

<img src='a.png' /> <img src='b.png' /> will always display a space between the images even if the border attribute is set to 0, whereas <img src='a.png' /><img src='b.png' /> will not.

Instead of use set_userdata you should use set_flashdata.

According to CI user guide:

CodeIgniter supports "flashdata", or session data that will only be available for the next server request, and are then automatically cleared. These can be very useful, and are typically used for informational or status messages (for example: "record 2 deleted").

http://ellislab.com/codeigniter/user-guide/libraries/sessions.html

What you are after is called partial function application.

Don't be fooled by those that don't understand the subtle difference between that and currying, they are different.

Partial function application can be used to implement, but is not currying. Here is a quote from a blog post on the difference:

Where partial application takes a function and from it builds a function which takes fewer arguments, currying builds functions which take multiple arguments by composition of functions which each take a single argument.

This has already been answered, see this question for your answer: How can I pre-set arguments in JavaScript function call?

Example:

var fr = partial(f, 1, 2, 3);

// now, when you invoke fr() it will invoke f(1,2,3)
fr();

Again, see that question for the details.

I also met the error message in raspberry pi 3, but my solution is reload kernel of camera after search on google, hope it can help you.

sudo modprobe bcm2835-v4l2

BTW, for this error please check your camera and file path is workable or not

I have found a trick solution. You can use the below codes.

$(".datepicker").datepicker({
/* any options you want */
beforeShowDay: function (date) {
    $('#ui-datepicker-div').css('clip', 'auto');
    return [true, '', ''];
    }
});

I'd start by completely filling in the Notification. Here is a sample project demonstrating the use of startForeground().

Create "topN" query on "clientip" and then histogram with count on "clientip" and set "topN" query as source. Then you will see count of different ips per time.

you can create a variable and send to ajax.

var m = { "Value": @Model.Value }

$.ajax({
    url: '<%=Url.Action("ModelPage")%>',
    type: "POST",
    data:  m,
    success: function(result) {
        $("div#updatePane").html(result);
    },

    complete: function() {
    $('form').onsubmit({ preventDefault: function() { } });

    }
});

All of model's field must bo ceated in m.

I thought I would provide a much more robust example, also in typescript, but it would be easy to convert to pure javascript. This function will query parents using either the ID like so "#my-element" or the class ".my-class" and unlike some of these answers will handle multiple classes. I found I named some similarly and so the examples above were finding the wrong things.

function queryParentElement(el:HTMLElement | null, selector:string) {
    let isIDSelector = selector.indexOf("#") === 0
    if (selector.indexOf('.') === 0 || selector.indexOf('#') === 0) {
        selector = selector.slice(1)
    }
    while (el) {
        if (isIDSelector) {
            if (el.id === selector) {
                return el
            }
        }
        else if (el.classList.contains(selector)) {
            return el;
        }
        el = el.parentElement;
    }
    return null;
}

To select by class name:

let elementByClassName = queryParentElement(someElement,".my-class")

To select by ID:

let elementByID = queryParentElement(someElement,"#my-element")

Here is a complete example that has been tested with Python 2.7.5 on CentOS 7.

#!/usr/bin/python

import sys, socket

def main(args):
    ip = args[1]
    port = int(args[2])
    sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    file = 'sample.csv'

    fp = open(file, 'r')
    for line in fp:
        sock.sendto(line.encode('utf-8'), (ip, port))
    fp.close()

main(sys.argv)

The program reads a file, sample.csv from the current directory and sends each line in a separate UDP packet. If the program it were saved in a file named send-udp then one could run it by doing something like:

$ python send-udp 192.168.1.2 30088

You can open a command prompt and do a

route print

and see your current routing table.

You can modify it by

route add    d.d.d.d mask m.m.m.m g.g.g.g 
route delete d.d.d.d mask m.m.m.m g.g.g.g 
route change d.d.d.d mask m.m.m.m g.g.g.g

these seem to work

I run a ping d.d.d.d -t change the route and it changes. (my test involved routing to a dead route and the ping stopped)

I had the same issue and figured it out today. I had to release the existing virtual drives before Genymotion would allow me to create a NEW virtual drive. Once you click create new drive, it prompts you to login to your Genymotion cloud account. Now I am actually able to run it. Hope this helps.

Edit* Also tried reinstalling AND repairing Virtualbox multiple times and still got same error. Only until I released the existing virtual drives did it start working.

Use the css "rotate()" method:

div {
  width: 100px;
  height: 100px;
  background-color: yellow;
  border: 1px solid black;
}

div#rotate{
  transform: rotate(90deg);
}

<div>
normal div
</div>
<br>

<div id="rotate">
This div is rotated 90 degrees
</div>

$ F = "text file.test.txt"  
$ echo ${F/*./}  
txt  

This caters for multiple dots and spaces in a filename, however if there is no extension it returns the filename itself. Easy to check for though; just test for the filename and extension being the same.

Naturally this method doesn't work for .tar.gz files. However that could be handled in a two step process. If the extension is gz then check again to see if there is also a tar extension.

The accepted answer does not "make Git "forget" about a file..." (historically). It only makes git ignore the file in the present/future.

This method makes git completely forget ignored files (past/present/future), but does not delete anything from working directory (even when re-pulled from remote).

This method requires usage of /.git/info/exclude (preferred) OR a pre-existing .gitignore in all the commits that have files to be ignored/forgotten. ¹

All methods of enforcing git ignore behavior after-the-fact effectively re-write history and thus have significant ramifications for any public/shared/collaborative repos that might be pulled after this process. ²

General advice: start with a clean repo - everything committed, nothing pending in working directory or index, and make a backup!

Also, the comments/revision history of this answer (and revision history of this question) may be useful/enlightening.

#commit up-to-date .gitignore (if not already existing)
#this command must be run on each branch

git add .gitignore
git commit -m "Create .gitignore"

#apply standard git ignore behavior only to current index, not working directory (--cached)
#if this command returns nothing, ensure /.git/info/exclude AND/OR .gitignore exist
#this command must be run on each branch

git ls-files -z --ignored --exclude-standard | xargs -0 git rm --cached

#Commit to prevent working directory data loss!
#this commit will be automatically deleted by the --prune-empty flag in the following command
#this command must be run on each branch

git commit -m "ignored index"

#Apply standard git ignore behavior RETROACTIVELY to all commits from all branches (--all)
#This step WILL delete ignored files from working directory UNLESS they have been dereferenced from the index by the commit above
#This step will also delete any "empty" commits.  If deliberate "empty" commits should be kept, remove --prune-empty and instead run git reset HEAD^ immediately after this command

git filter-branch --tree-filter 'git ls-files -z --ignored --exclude-standard | xargs -0 git rm -f --ignore-unmatch' --prune-empty --tag-name-filter cat -- --all

#List all still-existing files that are now ignored properly
#if this command returns nothing, it's time to restore from backup and start over
#this command must be run on each branch

git ls-files --other --ignored --exclude-standard

Finally, follow the rest of this GitHub guide (starting at step 6) which includes important warnings/information about the commands below.

git push origin --force --all
git push origin --force --tags
git for-each-ref --format="delete %(refname)" refs/original | git update-ref --stdin
git reflog expire --expire=now --all
git gc --prune=now

Other devs that pull from now-modified remote repo should make a backup and then:

#fetch modified remote

git fetch --all

#"Pull" changes WITHOUT deleting newly-ignored files from working directory
#This will overwrite local tracked files with remote - ensure any local modifications are backed-up/stashed

git reset FETCH_HEAD

Footnotes

¹ Because /.git/info/exclude can be applied to all historical commits using the instructions above, perhaps details about getting a .gitignore file into the historical commit(s) that need it is beyond the scope of this answer. I wanted a proper .gitignore to be in the root commit, as if it was the first thing I did. Others may not care since /.git/info/exclude can accomplish the same thing regardless where the .gitignore exists in the commit history, and clearly re-writing history is a very touchy subject, even when aware of the ramifications.

FWIW, potential methods may include git rebase or a git filter-branch that copies an external .gitignore into each commit, like the answers to this question

² Enforcing git ignore behavior after-the-fact by committing the results of a standalone git rm --cached command may result in newly-ignored file deletion in future pulls from the force-pushed remote. The --prune-empty flag in the following git filter-branch command avoids this problem by automatically removing the previous "delete all ignored files" index-only commit. Re-writing git history also changes commit hashes, which will wreak havoc on future pulls from public/shared/collaborative repos. Please understand the ramifications fully before doing this to such a repo. This GitHub guide specifies the following:

Tell your collaborators to rebase, not merge, any branches they created off of your old (tainted) repository history. One merge commit could reintroduce some or all of the tainted history that you just went to the trouble of purging.

Alternative solutions that do not affect the remote repo are git update-index --assume-unchanged </path/file> or git update-index --skip-worktree <file>, examples of which can be found here.

If you want to apply rotation on the axes object, the easiest way is using tick_params. For example.

ax.tick_params(axis='x', labelrotation=90)

Matplotlib documentation reference here.

This is useful when you have an array of axes as returned by plt.subplots, and it is more convenient than using set_xticks because in that case you need to also set the tick labels, and also more convenient that those that iterate over the ticks (for obvious reasons)

No need to go in such deep technicalities, and get yourself blasted. Let me explain it in the most easiest way. We all have studied "Sets" during our school-age in Mathematics. Just consider 3D numpy array as the formation of "sets".

x = np.zeros((2,3,4)) 

Simply Means:

2 Sets, 3 Rows per Set, 4 Columns

Example:

Input

x = np.zeros((2,3,4))

Output

Set # 1 ---- [[[ 0.,  0.,  0.,  0.],  ---- Row 1
               [ 0.,  0.,  0.,  0.],  ---- Row 2
               [ 0.,  0.,  0.,  0.]], ---- Row 3 
    
Set # 2 ----  [[ 0.,  0.,  0.,  0.],  ---- Row 1
               [ 0.,  0.,  0.,  0.],  ---- Row 2
               [ 0.,  0.,  0.,  0.]]] ---- Row 3

Explanation: See? we have 2 Sets, 3 Rows per Set, and 4 Columns.

Note: Whenever you see a "Set of numbers" closed in double brackets from both ends. Consider it as a "set". And 3D and 3D+ arrays are always built on these "sets".

You can also use logical tests

x <- data.frame(a = c(0,1,2,NA), b = c(0,NA,1,2), c = c(NA, 0, 1, 2)) 
x
x$a <- replace(x$a, is.na(x$a), 0)
x
x$b <- replace(x$b, x$b==2, 333)

After some testing with an icon with 8, 16, 20, 24, 32, 40, 48, 64, 96, 128 and 256 pixels (256 in PNG) in Windows 7:

• At 100% resolution: Explorer uses 16, 40, 48, and 256. Windows Photo Viewer uses 96. Paint uses 256.
• At 125% resolution: Explorer uses 20, 40, and 256. Windows Photo Viewer uses 96. Paint uses 256.
• At 150% resolution: Explorer uses 24, 48, and 256. Windows Photo Viewer uses 96. Paint uses 256.
• At 200% resolution: Explorer uses 40, 64, 96, and 256. Windows Photo Viewer uses 128. Paint uses 256.

So 8, 32 were never used (it's strange to me for 32) and 128 only by Windows Photo Viewer with a very high dpi screen, i.e. almot never used.

It means your icon should at least provide 16, 48 and 256 for Windows 7. For supporting newer screens with high resolutions, you should provide 16, 20, 24, 40, 48, 64, 96, and 256. For Windows 7, all pictures can be compressed using PNG but for backward compatibility with Windows XP, 16 to 48 should not be compressed.

I Think this is because of IIS is unable to find the root folder. i.e wwwroot. Restarting the IIS wont be helpful in some scenarios. if the root path has changed, you should bring it back to %SystemDrive%\inetpub\wwwroot

by right clicking sites node in IIS and changing physical path to the above one.

By default, docker container will exit immediately if you do not have any task running on the container.

To keep the container running in the background, try to run it with --detach (or -d) argument.

For examples:

docker pull debian

docker run -t -d --name my_debian debian
e7672d54b0c2

docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
e7672d54b0c2        debian              "bash"              3 minutes ago       Up 3 minutes                            my_debian

#now you can execute command on the container
docker exec -it my_debian bash
root@e7672d54b0c2:/# 

Put the line $this->db->order_by("course_name","desc"); at top of your query. Like

$this->db->order_by("course_name","desc");$this->db->select('*');
$this->db->where('tennant_id',$tennant_id);
$this->db->from('courses');
$query=$this->db->get();
return $query->result();

This is a block element, in order for it to be able to receive focus, you need to add tabindex attribute to it, as in

<div id="myID" tabindex="1"></div>

Tabindex will allow this element to receive focus. Use tabindex="-1" (or indeed, just get rid of the attribute alltogether) to disallow this behaviour.

And then you can simply

if ($("#myID").is(":focus")) {...}

Or use the

$(document.activeElement)

As been suggested previously.

I removed this error by write the following code

Open Terminal

1. openssl req -newkey rsa:2048 -new -nodes -keyout key.pem -out csr.pem

2. openssl x509 -req -days 365 -in csr.pem -signkey key.pem -out server.crt

Now use the server.crt and key.pem file

app.js or server.js file

var https = require('https');
var https_options = {
  key: fs.readFileSync('key.pem', 'utf8'),
  cert: fs.readFileSync('server.crt', 'utf8')
};

var server = https.createServer(https_options, app).listen(PORT);
console.log('HTTPS Server listening on %s:%s', HOST, PORT);

It works but the certificate is not trusted. You can view the image in image file.

Why the base class' default constructor is called? Turns out it's not always be the case. Any constructor of the base class (with different signatures) can be invoked from the derived class' constructor. In your case, the default constructor is called because it has no parameters so it's default.

When a derived class is created, the order the constructors are called is always Base -> Derived in the hierarchy. If we have:

class A {..}
class B : A {...}
class C : B {...}
C c;

When c is create, the constructor for A is invoked first, and then the constructor for B, and then the constructor for C.

To guarantee that order, when a derived class' constructor is called, it always invokes the base class' constructor before the derived class' constructor can do anything else. For that reason, the programmer can manually invoke a base class' constructor in the only initialisation list of the derived class' constructor, with corresponding parameters. For instance, in the following code, Derived's default constructor will invoke Base's constructor Base::Base(int i) instead of the default constructor.

Derived() : Base(5)
{      
}

If there's no such constructor invoked in the initialisation list of the derived class' constructor, then the program assumes a base class' constructor with no parameters. That's the reason why a constructor with no parameters (i.e. the default constructor) is invoked.

Hope this helps.

Or put your logic into a tidy little class.

public class PrettyPrintingMap<K, V> {
    private Map<K, V> map;

    public PrettyPrintingMap(Map<K, V> map) {
        this.map = map;
    }

    public String toString() {
        StringBuilder sb = new StringBuilder();
        Iterator<Entry<K, V>> iter = map.entrySet().iterator();
        while (iter.hasNext()) {
            Entry<K, V> entry = iter.next();
            sb.append(entry.getKey());
            sb.append('=').append('"');
            sb.append(entry.getValue());
            sb.append('"');
            if (iter.hasNext()) {
                sb.append(',').append(' ');
            }
        }
        return sb.toString();

    }
}

Usage:

Map<String, String> myMap = new HashMap<String, String>();

System.out.println(new PrettyPrintingMap<String, String>(myMap));

Note: You can also put that logic into a utility method.

break causes the program counter to jump out of the scope of the innermost loop

for(i = 0; i < 10; i++)
{
    if(i == 2)
        break;
}

Works like this

for(i = 0; i < 10; i++)
{
    if(i == 2)
        goto BREAK;
}
BREAK:;

continue jumps to the end of the loop. In a for loop, continue jumps to the increment expression.

for(i = 0; i < 10; i++)
{
    if(i == 2)
        continue;

    printf("%d", i);
}

Works like this

for(i = 0; i < 10; i++)
{
    if(i == 2)
        goto CONTINUE;

    printf("%d", i);

    CONTINUE:;
}

You can also try this, suppose if you want to make a back image button and you have "500x500 png" and want it to fit in small button size.

Use dp to fix ImageView's size.

add this line of code to your Imageview.

android:scaleType="fitXY"

EXAMPLE:

<ImageView
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:id="@+id/imageView2"
        android:src="@drawable/Backicon"
        android:scaleType="fitXY"
        />

Another solution would be as below where the list is placed under a drop-down button.

  <button class="btn dropdown-toggle btn-primary btn-sm" data-toggle="dropdown"
    >Markets<span class="caret"></span></button>

    <ul class="dropdown-menu", style="height:40%; overflow:hidden; overflow-y:scroll;">
      {{ form.markets }}
    </ul>

Whichever of the three you go with, compare your variables against FALSE, or false.

Historically it is a bad idea to compare anything to true (1) in c or c++. Only false is guaranteed to be zero (0). True is any other value.   Many compiler vendors have these definitions somewhere in their headers.  

#define TRUE 1
#define FALSE 0

This has led too many people down the garden path.   Many library functions besides chartype return nonzero values not equal to 1 on success. There is a great deal of legacy code out there with the same behavior.

This is an old question, anyway today the best practice is by using Object.defineProperty

const object1 = {};

Object.defineProperty(object1, 'property1', {
  value: 42,
  writable: false
});

object1.property1 = 77;
// throws an error in strict mode

console.log(object1.property1);
// expected output: 42

You could also use this:

$('.slider').slick({
   //other settings ................
   respondTo: 'slider', //makes the slider to change width depending on the container it is in
   adaptiveHeight: true //makes the height change depending on the height of the element inside
})

If you wrote the console application you can make it hidden by default.

Create a new console app then then change the "Output Type" type to "Windows Application" (done in the project properties)

I encounted this error and found that it was because the "strict" parameter was set to true in the tsconfig.json file. Just set it "false" (obviously). In my case I had generated the tsconfig file from the cmd prompt and simply missed the "strict" parameter, which was located further down in the file.

You have the field in a string, so you'll need to convert it to datetime

order by CONVERT(datetime, EventDate ) desc

array_reverse() does not alter the source array, but returns a new array. (See array_reverse().) So you either need to store the new array first or just use function within the declaration of your for loop.

<?php 
    $input = array('a', 'b', 'c');
    foreach (array_reverse($input) as $value) {
        echo $value."\n";
    }
?>

The output will be:

c
b
a

So, to address to OP, the code becomes:

<?php
    $j=1;     
    foreach ( array_reverse($skills_nav) as $skill ) {
        $a = '<li><a href="#" data-filter=".'.$skill->slug.'">';
        $a .= $skill->name;                 
        $a .= '</a></li>';
        echo $a;
        echo "\n";
        $j++;

Lastly, I'm going to guess that the $j was either a counter used in an initial attempt to get a reverse walk of $skills_nav, or a way to count the $skills_nav array. If the former, it should be removed now that you have the correct solution. If the latter, it can be replaced, outside of the loop, with a $j = count($skills_nav).

want to convert the column name Amount as float number with 2 decimals

CASE WHEN EXISTS (SELECT Amount From InvoiceFee Ifee WHERE IFEE.InvoiceId = 
DIR.InvoiceId AND FeeId = 'Freight Cost')
     THEN  CAST ((SELECT Amount From InvoiceFee Ifee WHERE IFEE.InvoiceId = 
DIR.InvoiceId AND FeeId = 'Freight Cost') AS VARCHAR)
            ELSE '' END AS FCost,

With pyEnchant.checker SpellChecker:

    d = SpellChecker("en_US")
    d.set_text(quote)
    errors = [err.word for err in d]
    return False if ((len(errors) > 4) or len(quote.split()) < 3) else True

print(is_in_english('“??????????????????????Q/V2166384296???????????????????'))

as a few people mentioned scala.io.Source is best to be avoided due to connection leaks.

Probably scalax and pure java libs like commons-io are the best options until the new incubator project (ie scala-io) gets merged.

Try using the CSS line-height atribute on your p tag that contains the br tag. Remember you can id your p tags if you want to isolate it, though it might be better using a div for isolation, IMO.

This means that your server is sending "text/html" instead of the already supported types. My solution was to add "text/html" to acceptableContentTypes set in AFURLResponseSerialization class. Just search for "acceptableContentTypes" and add @"text/html" to the set manually.

Of course, the ideal solution is to change the type sent from the server, but for that you will have to talk with the server team.

Just add the line: sql_mode = "NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

inside file: /etc/mysql/mysql.conf.d/mysqld.cnf

then sudo service mysql restart

You need to tell manage.py the local ip address and the port to bind to. Something like python manage.py runserver 192.168.23.12:8000. Then use that same ip and port from the other machine. You can read more about it here in the documentation.

If nothing of the above helps, check if there is margin-top set on some of the (some levels below) nested DOM element(s).

It will be not recognizable when you inspect body element itself in the debugger. It will only be visible when you unfold several elements nested down in body element in Chrome Dev Tools elements debugger and check if there is one of them with margin-top set.

The below is the upper part of a site screen shot and the corresponding Chrome Dev Tools view when you inspect body tag.

No sign of top margin here and you have resetted all the browser-scpecific CSS properties as per answers above but that unwanted white space is still here.

The following is a view when you inspect the right nested element. It is clearly seen the orange'ish top-margin is set on it. This is the one that causes the white space on top of body element.

On that found element replace margin-top with padding-top if you need space above it and yet not to leak it above the body tag.

Hope that helps :)

Imagine the .js files are placed in /my-site/some/path/ui/js/myfile.js

So normally the script tag would look like:

<script src="/my-site/some/path/ui/js/myfile.js"></script>

Now change that to:

<script src="/my-site/some/path/ui-1111111111/js/myfile.js"></script>

Now of course that will not work. To make it work you need to add one or a few lines to your .htaccess The important line is: (entire .htaccess at the bottom)

RewriteRule ^my-site\/(.*)\/ui\-([0-9]+)\/(.*) my-site/$1/ui/$3 [L]

So what this does is, it kind of removes the 1111111111 from the path and links to the correct path.

So now if you make changes you just have to change the number 1111111111 to whatever number you want. And however you include your files you can set that number via a timestamp when the js-file has last been modified. So cache will work normally if the number does not change. If it changes it will serve the new file (YES ALWAYS) because the browser get's a complete new URL and just believes that file is so new he must go get it.

You can use this for CSS, favicons and what ever gets cached. For CSS just use like so

<link href="http://my-domain.com/my-site/some/path/ui-1492513798/css/page.css" type="text/css" rel="stylesheet">

And it will work! Simple to update, simple to maintain.

The promised full .htaccess

If you have no .htaccess yet this is the minimum you need to have there:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /

    RewriteRule ^my-site\/(.*)\/ui\-([0-9]+)\/(.*) my-site/$1/ui/$3 [L]
</IfModule>

An Updated version that works in chrome:

function SelectText(element) {
    var doc = document;
    var text = doc.getElementById(element);    
    if (doc.body.createTextRange) { // ms
        var range = doc.body.createTextRange();
        range.moveToElementText(text);
        range.select();
    } else if (window.getSelection) {
        var selection = window.getSelection();
        var range = doc.createRange();
        range.selectNodeContents(text);
        selection.removeAllRanges();
        selection.addRange(range);

    }
}

$(function() {
    $('p').click(function() {
        SelectText("selectme");

    });
});

simple and short solution add below style:

style="vertical-align: text-bottom;"

I'm assuming you mean that 'use' means read, but what i'll explain for the read case can be basically reversed for the write case.

so you end up with a byte[]. this could represent any kind of data which may need special types of conversions (character, encrypted, etc). let's pretend you want to write this data as is to a file.

firstly you could create a ByteArrayInputStream which is basically a mechanism to supply the bytes to something in sequence.

then you could create a FileOutputStream for the file you want to create. there are many types of InputStreams and OutputStreams for different data sources and destinations.

lastly you would write the InputStream to the OutputStream. in this case, the array of bytes would be sent in sequence to the FileOutputStream for writing. For this i recommend using IOUtils

byte[] bytes = ...;//
ByteArrayInputStream in = new ByteArrayInputStream(bytes);
FileOutputStream out = new FileOutputStream(new File(...));
IOUtils.copy(in, out);
IOUtils.closeQuietly(in);
IOUtils.closeQuietly(out);

and in reverse

FileInputStream in = new FileInputStream(new File(...));
ByteArrayOutputStream out = new ByteArrayOutputStream();
IOUtils.copy(in, out);
IOUtils.closeQuietly(in);
IOUtils.closeQuietly(out);
byte[] bytes = out.toByteArray();

if you use the above code snippets you'll need to handle exceptions and i recommend you do the 'closes' in a finally block.

Another alternative:

head -$((${RANDOM} % `wc -l < file` + 1)) file | tail -1

Nothing stops you from doing

moveUp = moveDown = moveLeft = moveRight = mouseDown = touchDown = false;

Check this example

var a, b, c;_x000D_
a = b = c = 10;_x000D_
console.log(a + b + c)

It's not how they work. You "start" a marquee style progress bar by making it visible, you stop it by hiding it. You could change the Style property.

Option 1:

sudo apt update && sudo apt install android-sdk

The location of Android SDK on Linux can be any of the following:

• /home/AccountName/Android/Sdk

• /usr/lib/android-sdk

• /Library/Android/sdk/

• /Users/[USER]/Library/Android/sdk

Option 2:

• Download the Android Studio.

• Extract downloaded .zip file.

  The extracted folder name will read somewhat like android-studio

To keep navigation easy, move this folder to Home directory.

• After moving, copy the moved folder by right clicking it. This action will place folder's location to clipboard.

• Use Ctrl Alt T to open a terminal

• Go to this folder's directory using cd /home/(USER NAME)/android-studio/bin/

• Type this command to make studio.sh executable: chmod +x studio.sh

• Type ./studio.sh

A pop up will be shown asking for installation settings. In my particular case, it is a fresh install so I'll go with selecting I do not have a previous version of Studio or I do not want to import my settings.

If you choose to import settings anyway, you may need to close any old project which is opened in order to get a working Android SDK.

From now onwards, setup wizard will guide you.

Android Studio can work with both Open JDK and Oracle's JDK (recommended). Incase, Open JDK is installed the wizard will recommend installing Oracle Java JDK because some UI and performance issues are reported while using OpenJDK.

The downside with Oracle's JDK is that it won't update with the rest of your system like OpenJDK will.

The wizard may also prompt about the input problems with IDEA .

Select install type

Verify installation settings

An emulator can also be configured as needed.

The wizard will start downloading the necessary SDK tools

The wizard may also show an error about Linux 32 Bit Libraries, which can be solved by using the below command:

sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1

After this, all the required components will be downloaded and installed automatically.

After everything is upto the mark, just click finish

To make a Desktop icon, go to 'Configure' and then click 'Create Desktop Entry'

It's not what the OP asked for (capturing groups) but you can extract the numbers using:

S='This is a sample 123 text and some 987 numbers'
echo "$S" | sed 's/ /\n/g' | sed -r '/([0-9]+)/ !d'

Gives the following:

123
987

As of PowerShell 6.0, Split-Path has an -Extenstion parameter. This means you can do:

$path | Split-Path -Extension

or

Split-Path -Path $path -Extension

For $path = "test.txt" both versions will return .txt, inluding the full stop.

There's a nice bookmarklet called Visual Event that can show you all the events attached to an element. It has color-coded highlights for different types of events (mouse, keyboard, etc.). When you hover over them, it shows the body of the event handler, how it was attached, and the file/line number (on WebKit and Opera). You can also trigger the event manually.

It can't find every event because there's no standard way to look up what event handlers are attached to an element, but it works with popular libraries like jQuery, Prototype, MooTools, YUI, etc.

When running the python file, you would normally do this

python app.py

To avoid these messsages. Inside the CLI (Command Line Interface), run these commands.

export FLASK_APP=app.py
export FLASK_RUN_HOST=127.0.0.1
export FLASK_ENV=development
export FLASK_DEBUG=0
flask run

This should work perfectlly. :) :)

See the mysql manual, Unicode Character Sets section:

For any Unicode character set, operations performed using the _general_ci collation are faster than those for the _unicode_ci collation. For example, comparisons for the utf8_general_ci collation are faster, but slightly less correct, than comparisons for utf8_unicode_ci. The reason for this is that utf8_unicode_ci supports mappings such as expansions; that is, when one character compares as equal to combinations of other characters. For example, in German and some other languages “ß” is equal to “ss”. utf8_unicode_ci also supports contractions and ignorable characters. utf8_general_ci is a legacy collation that does not support expansions, contractions, or ignorable characters. It can make only one-to-one comparisons between characters.

So to summarize, utf_general_ci uses a smaller and less correct (according to the standard) set of comparisons than utf_unicode_ci which should implement the entire standard. The general_ci set will be faster because there is less computation to do.

You can validate point a and b compactly by doing something like the following:

#!/bin/sh
MYVAL=$(echo ${1} | awk '/^[0-9]+$/')
MYVAL=${MYVAL:?"Usage - testparms <number>"}
echo ${MYVAL}

Which gives us ...

$ ./testparams.sh 
Usage - testparms <number>

$ ./testparams.sh 1234
1234

$ ./testparams.sh abcd
Usage - testparms <number>

This method should work fine in sh.

remote server> cd /home/ec2-user

If you use the relative version on http://www.foo.com/abc your browser will look at http://www.foo.com/abc/kitten.png for the image and would get 404 - Not found.

That offset is basically the x,y position that the browser has calculated for the element based on it's position css attribute. So if you put a <br> before it or any other element, it would change the offset. For example, you could set it to 0 by:

#inputBox{position:absolute;top:0px;left:0px;}

or

#inputBox{position:relative;top:-12px;left:-2px;}

Therefore, whatever positioning issue you have, is not necessarily an issue with offset, though you could always fix it by playing with the top,left,right and bottom attributes.

Is your problem browser incompatibility?

The following command worked for me using the command prompt (As an Administrator) in Windows:

mysqlcheck -u root -p -A --auto-repair

Run mysqlcheck with the root user, prompt for a password, check all databases, and auto-repair any corrupted tables.

Try swapspace http://pqxx.org/development/swapspace/

Most distros have it packaged.

On EC2 you might want to change "swappath" to /mnt or high-iops disk.

For getting Drawable id from String resource name I am using this code:

private int getResId(String resName) {
    int defId = -1;
    try {
        Field f = R.drawable.class.getDeclaredField(resName);
        Field def = R.drawable.class.getDeclaredField("transparent_flag");
        defId = def.getInt(null);
        return f.getInt(null);
    } catch (NoSuchFieldException | IllegalAccessException e) {
        return defId;
    }
}

Let's not forget math.hypot:

dist = math.hypot(x2-x1, y2-y1)

Here's hypot as part of a snippet to compute the length of a path defined by a list of (x, y) tuples:

from math import hypot

pts = [
    (10,10),
    (10,11),
    (20,11),
    (20,10),
    (10,10),
    ]

# Py2 syntax - no longer allowed in Py3
# ptdiff = lambda (p1,p2): (p1[0]-p2[0], p1[1]-p2[1])
ptdiff = lambda p1, p2: (p1[0]-p2[0], p1[1]-p2[1])

diffs = (ptdiff(p1, p2) for p1, p2 in zip (pts, pts[1:]))
path = sum(hypot(*d) for d in  diffs)
print(path)

I guess it's just because the onblur event is called as a result of the input losing focus, there isn't a blur action associated with an input, like there is a click action associated with a button

To calculate gradients, the machine learning community uses Autograd:

"Efficiently computes derivatives of numpy code."

To install:

pip install autograd

Here is an example:

import autograd.numpy as np
from autograd import grad

def fct(x):
    y = x**2+1
    return y

grad_fct = grad(fct)
print(grad_fct(1.0))

It can also compute gradients of complex functions, e.g. multivariate functions.

For info : in some Apache2 conf you must add the DirectoryIndex command in mods_enabled/dir.conf (it's not located in apache2.conf)

Option 1 You can set a Slack channel to automatically delete messages after 1 day, but it's a little hidden. First, you have to go to your Slack Workspace Settings, Message Retention & Deletion, and check "Let workspace members override these settings". After that, in the Slack client you can open a channel, click the gear, and click "Edit message retention..."

Option 2 The slack-cleaner command line tool that others have mentioned.

Option 3 Below is a little Python script that I use to clear Private channels. Can be a good starting point if you want more programmatic control of deletion. Unfortunately Slack has no bulk-delete API, and they rate-limit the individual delete to 50 per minute, so it unavoidably takes a long time.

There is always intval() - Not sure if this is what you were looking for...

example: -

$floatValue = 4.5;
echo intval($floatValue);    // Returns 4

It won't round off the value to an integer, but will strip out the decimal and trailing digits, and return the integer before the decimal.

Here is some documentation for this: - http://php.net/manual/en/function.intval.php

If you are using SQL 2005 you can do something like this...

SELECT rs.Field1,rs.Field2 
    FROM (
        SELECT Field1,Field2, Rank() 
          over (Partition BY Section
                ORDER BY RankCriteria DESC ) AS Rank
        FROM table
        ) rs WHERE Rank <= 10

If your RankCriteria has ties then you may return more than 10 rows and Matt's solution may be better for you.

Thanks for your answers. I missed that my data is stored in a List<String> which is passed to the tested method. The mistake was that I put the string into the first element of the ArrayList. That's why I thought the String consists of just one single line, because the debugger showed me only one entry.

1. clone $args
2. push your args in new array
3. & $path $args

Demo:

$exePath = $env:NGINX_HOME + '/nginx.exe'
$myArgs = $args.Clone()

$myArgs += '-p'
$myArgs += $env:NGINX_HOME

& $exepath $myArgs

I suggest using cowplot. From their R vignette:

# load cowplot
library(cowplot)

# down-sampled diamonds data set
dsamp <- diamonds[sample(nrow(diamonds), 1000), ]

# Make three plots.
# We set left and right margins to 0 to remove unnecessary spacing in the
# final plot arrangement.
p1 <- qplot(carat, price, data=dsamp, colour=clarity) +
   theme(plot.margin = unit(c(6,0,6,0), "pt"))
p2 <- qplot(depth, price, data=dsamp, colour=clarity) +
   theme(plot.margin = unit(c(6,0,6,0), "pt")) + ylab("")
p3 <- qplot(color, price, data=dsamp, colour=clarity) +
   theme(plot.margin = unit(c(6,0,6,0), "pt")) + ylab("")

# arrange the three plots in a single row
prow <- plot_grid( p1 + theme(legend.position="none"),
           p2 + theme(legend.position="none"),
           p3 + theme(legend.position="none"),
           align = 'vh',
           labels = c("A", "B", "C"),
           hjust = -1,
           nrow = 1
           )

# extract the legend from one of the plots
# (clearly the whole thing only makes sense if all plots
# have the same legend, so we can arbitrarily pick one.)
legend_b <- get_legend(p1 + theme(legend.position="bottom"))

# add the legend underneath the row we made earlier. Give it 10% of the height
# of one plot (via rel_heights).
p <- plot_grid( prow, legend_b, ncol = 1, rel_heights = c(1, .2))
p

UPDATE 17/03/2017

Original solution won't work anymore. The spinners are part of shadow dom. For now just to hide in chrome use:

input[type=number]::-webkit-inner-spin-button {_x000D_
  -webkit-appearance: none;_x000D_
}

<input type="number" />

or to always show:

input[type=number]::-webkit-inner-spin-button {_x000D_
  opacity: 1;_x000D_
}

<input type="number" />

You can try the following but keep in mind that works only for Chrome:

input[type=number]::-webkit-inner-spin-button { _x000D_
    -webkit-appearance: none;_x000D_
    cursor:pointer;_x000D_
    display:block;_x000D_
    width:8px;_x000D_
    color: #333;_x000D_
    text-align:center;_x000D_
    position:relative;_x000D_
}_x000D_
_x000D_
input[type=number]::-webkit-inner-spin-button:before,_x000D_
input[type=number]::-webkit-inner-spin-button:after {_x000D_
    content: "^";_x000D_
    position:absolute;_x000D_
    right: 0;_x000D_
}_x000D_
_x000D_
input[type=number]::-webkit-inner-spin-button:before {_x000D_
    top:0px;_x000D_
}_x000D_
_x000D_
input[type=number]::-webkit-inner-spin-button:after {_x000D_
    bottom:0px;_x000D_
    -webkit-transform: rotate(180deg);_x000D_
}

<input type="number" />

I used this method for updating a label but you could easily change it to a textbox:

Class:

public Class1
{
    public Form_Class formToOutput;

    public Class1(Form_Class f){
        formToOutput = f;
    }

    // Then call this method and pass whatever string
    private void Write(string s)
    {
        formToOutput.MethodToBeCalledByClass(s);
    }
}

Form methods that will do the updating:

public Form_Class{

    // Methods that will do the updating
    public void MethodToBeCalledByClass(string messageToSend)
    {
       if (InvokeRequired) { 
           Invoke(new OutputDelegate(UpdateText),messageToSend); 
       }
    }

    public delegate void OutputDelegate(string messageToSend);
    public void UpdateText(string messageToSend)
    {
       label1.Text = messageToSend;
    }
}

Finally

Just pass the form through the constructor:

Class1 c = new Class1(this);

Do you really need to do that programmatically?

Just considering the title: You could use a ShapeDrawable as android:background…

For example, let's define res/drawable/my_custom_background.xml as:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
  <corners
      android:radius="2dp"
      android:topRightRadius="0dp"
      android:bottomRightRadius="0dp"
      android:bottomLeftRadius="0dp" />
  <stroke
      android:width="1dp"
      android:color="@android:color/white" />
</shape>

and define android:background="@drawable/my_custom_background".

I've not tested but it should work.

Update:

I think that's better to leverage the xml shape drawable resource power if that fits your needs. With a "from scratch" project (for android-8), define res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Reported to work on a gingerbread device. Note that you'll need to relate android:padding of the LinearLayout to the android:width shape/stroke's value. Please, do not use @android:color/white in your final application but rather a project defined color.

You could apply android:background="@drawable/border" android:padding="10dip" to each of the LinearLayout from your provided sample.

As for your other posts related to display some circles as LinearLayout's background, I'm playing with Inset/Scale/Layer drawable resources (see Drawable Resources for further information) to get something working to display perfect circles in the background of a LinearLayout but failed at the moment…

Your problem resides clearly in the use of getBorder.set{Width,Height}(100);. Why do you do that in an onClick method?

I need further information to not miss the point: why do you do that programmatically? Do you need a dynamic behavior? Your input drawables are png or ShapeDrawable is acceptable? etc.

To be continued (maybe tomorrow and as soon as you provide more precisions on what you want to achieve)…

There was a really nice post on the Spring Blog from Keith Donald detailing howto Obtain Spring 3 Aritfacts with Maven, with comments detailing when you'd need each of the dependencies...

In Pycharm Just use Shift+Tab to move a block of code left.

In my experience this problem happens if you try to build on a device that is not registered in your developer center or is not enabled inside provisioning profile that you are using.

1) Add the device to the developer center. In XCode 5 you'll still find a button "add to member center" inside the Organizer window. In XCode 6 i suggest to copy the device ID and manually add it to the device section of your member center.

2) Edit the provisioning profile you're using to include the device you have just added. Save and synchronize provisioning profiles from XCode.

Clean, and it is on.

From my experience I've found that some commands which run in IPython do not run in base Python. For example, pwd and ls don't work alone in base Python. However they will work if prefaced with a % such as: %pwd and %ls.

Also, in IPython, you can run the cd command like: cd C:\Users\... This doesn't seem to work in base python, even when prefaced with a % however.

You could try updating the composer:

sudo composer self-update

If that doest works remove composer files & then use: SSH into terminal & type :

$ cd ~
$ sudo curl -sS https://getcomposer.org/installer | sudo php
$ sudo mv composer.phar /usr/local/bin/composer
$ sudo ln -s /usr/local/bin/composer /usr/bin/composer

If you face an error that says: PHP Fatal error: Uncaught exception 'ErrorException' with message 'proc_open(): fork failed - Cannot allocate memory' in phar

/bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
/sbin/mkswap /var/swap.1
/sbin/swapon /var/swap.1

To install package use:

composer global require "package-name"

If you are trying to use this with panels only (not accordeon), try this code:

<div class="panel panel-default">
    <div class="panel-heading">
        <h4 class="panel-title">
            <a class="collapse-toggle" data-toggle="collapse" href="#collapseExample" aria-expanded="false" aria-controls="collapseExample">Panel heading with title</a>
        </h4>
    </div>
    <div id="collapseExample" class="panel-collapse collapse in">
        <div class="panel-body">
            Panel content
        </div>
    </div>
</div>

jQuery was written using JavaScript, and is a library to be used by JavaScript. You cannot learn jQuery without learning JavaScript.

Likely, you'll want to learn and use both of them. go through following breif diffrence http://www.slideshare.net/umarali1981/difference-between-java-script-and-jquery

Basically, this way you combine things because jQuery is a framework which mostly focuses on HTML elements, you basically preventing the default, but at the same time, you stop propagation to bubble up.

So we can simply say, return false in jQuery is equal to:

return false is e.preventDefault AND e.stopPropagation

But also don't forget it's all in jQuery or DOM related functions, when you run it on the element, basically, it prevents everything from firing including the default behaviour and propagation of the event.

Basically before starting using return false;, first understand what e.preventDefault(); and e.stopPropagation(); do, then if you think you need both at the same time, then simply use it.

So basically this code below:

$('div').click(function () {
  return false;
});

is equal to this code:

$('div').click(function (event) {
  event.preventDefault();
  event.stopPropagation();
});

Simpler solution:

var dt = $('#table_scroll').dataTable();

$.getJSON(url, null, function (json) {
    dt.fnClearTable();
    dt.fnAddData(json.aaData);
    dt.fnDraw();
});

try this:

SELECT * FROM OPENROWSET('SQLNCLI', 'Server=YOUR SERVER;Trusted_Connection=yes;','SELECT * FROM Table1') AS a
UNION
SELECT * FROM OPENROWSET('SQLNCLI', 'Server=ANOTHER SERVER;Trusted_Connection=yes;','SELECT * FROM Table1') AS a

If you need a button like this:

You can use RaisedButton and use the child property to do this. You need to add a Row and inside row you can add a Text widget and an Icon Widget to achieve this. If you want to use png image, you can use similar widget to achieve this.

RaisedButton(
    onPressed: () {},
    color: Theme.of(context).accentColor,
    child: Padding(
      padding: EdgeInsets.fromLTRB(
          SizeConfig.safeBlockHorizontal * 5,
          0,
          SizeConfig.safeBlockHorizontal * 5,
          0),
      child: Row(
        mainAxisAlignment: MainAxisAlignment.spaceBetween,
        children: <Widget>[
          Text(
            'Continue',
            style: TextStyle(
              fontSize: 20,
              fontWeight: FontWeight.w700,
              color: Colors.white,
            ),
          ),
          Icon(
            Icons.arrow_forward,
            color: Colors.white,
          )
        ],
      ),
    ),
  ),

Use the setState function. So you could do

       this.setState({this.state.foo.bar:123}) 

inside the handle event method.

Once, the state is updated, it will trigger changes, and re-render will take place.

The NEW values (or NEW_BUFFER as you have renamed them) are only available when INSERTING and UPDATING. For DELETING you would need to use OLD (OLD_BUFFER). So your trigger would become:

CREATE or REPLACE TRIGGER test001
  AFTER INSERT OR DELETE OR UPDATE ON tabletest001
  REFERENCING OLD AS old_buffer NEW AS new_buffer 
  FOR EACH ROW WHEN (new_buffer.field1 = 'HBP00' OR old_buffer.field1 = 'HBP00') 

You may need to add logic inside the trigger to cater for code that updates field1 from 'HBP000' to something else.

You can find the answer to your question on the following page:

If you are restoring the folder don't forget to chown the files to mysql:mysql

chown -R mysql:mysql /var/lib/mysql-data

otherwise you will get errors when trying to drop a database or add new column etc..

and restart MySQL

service mysql restart

Run the below command to create a migration file:

rails g migration ChangeHasedPasswordToHashedPassword

Then in the file generated in the db/migrate folder, write rename_column as below:

class ChangeOldCoulmnToNewColumn < ActiveRecord::Migration
  def change
     rename_column :table_name, :hased_password, :hashed_password
  end
end

@maxisam thanks for ngx-window-token. I was doing something similar but switched to yours. This is my service for listening to window resize events and notifying subscribers.

}_x000D_
_x000D_

export class WindowSizeService {_x000D_
_x000D_
    constructor( @Inject(WINDOW) private _window: any ) {_x000D_
        Observable.fromEvent(_window, 'resize')_x000D_
        .auditTime(100)_x000D_
        .map(event => <WindowSize>{width: event['currentTarget'].innerWidth, height: event['currentTarget'].innerHeight})_x000D_
        .subscribe((windowSize) => {_x000D_
            this.windowSizeChanged$.next(windowSize);_x000D_
        });_x000D_
    }_x000D_
_x000D_
    readonly windowSizeChanged$ = new BehaviorSubject<WindowSize>(<WindowSize>{width: this._window.innerWidth, height: this._window.innerHeight});_x000D_
}

Short and sweet and works like a charm.

Completely reset?

1. Delete the .git directory locally.

2. Recreate the git repostory:

   $ cd (project-directory)
   $ git init
   $ (add some files)
   $ git add .
   $ git commit -m 'Initial commit'
   

3. Push to remote server, overwriting. Remember you're going to mess everyone else up doing this … you better be the only client.

   $ git remote add origin <url>
   $ git push --force --set-upstream origin master
   

How can I check to see if a database in SQL Server is case-sensitive?

You can use below query that returns your informed database is case sensitive or not or is in binary sort(with null result):

;WITH collations AS (
    SELECT 
        name,
        CASE 
            WHEN description like '%case-insensitive%' THEN 0 
            WHEN description like '%case-sensitive%' THEN 1 
        END isCaseSensitive
    FROM 
        sys.fn_helpcollations()
)
SELECT *
FROM collations
WHERE name = CONVERT(varchar, DATABASEPROPERTYEX('yourDatabaseName','collation'));

For more read this MSDN information ;).

An alternative is to use String.format:

double[] arr = { 23.59004,
    35.7,
    3.0,
    9
};

for ( double dub : arr ) {
  System.out.println( String.format( "%.2f", dub ) );
}

output:

23.59
35.70
3.00
9.00

You could also use System.out.format (same method signature), or create a java.util.Formatter which works in the same way.

As of 2018, there is also iText7 (A next iteration of old iTextSharp library) and its HTML to PDF package available: itext7.pdfhtml

Usage is straightforward:

HtmlConverter.ConvertToPdf(
    new FileInfo(@"Path\to\Html\File.html"),
    new FileInfo(@"Path\to\Pdf\File.pdf")
);

Method has many more overloads.

Update: iText* family of products has dual licensing model: free for open source, paid for commercial use.

Remove single quotes around @username, and with respect to oracle use : with parameter name instead of @, like:

OracleCommand oraCommand = new OracleCommand("SELECT fullname FROM sup_sys.user_profile
                           WHERE domain_user_name = :userName", db);
oraCommand.Parameters.Add(new OracleParameter("userName", domainUser));

Source: Using Parameters

Use df[df['B']==3]['A'].values if you just want item itself without the brackets

Try removing the float attribute from span6:

{ float:none !important; }

You can add color in the style rule of your input: color:#ccc;

Make's substitutions feature is nice and helped me to write

%.i: src/%.c $(INCLUDE)
        gcc -E $(CPPFLAGS) $(INCLUDE:%=-I %) $< > $@

You might find this useful, because it asks make to check for changes in include folders too

Use the isSelected method.

You can also use an ItemListener so you'll be notified when it's checked or unchecked.

Simplest solution

Use numpy.dot or a.dot(b). See the documentation here.

>>> a = np.array([[ 5, 1 ,3], 
                  [ 1, 1 ,1], 
                  [ 1, 2 ,1]])
>>> b = np.array([1, 2, 3])
>>> print a.dot(b)
array([16, 6, 8])

This occurs because numpy arrays are not matrices, and the standard operations *, +, -, / work element-wise on arrays. Instead, you could try using numpy.matrix, and * will be treated like matrix multiplication.

Other Solutions

Also know there are other options:

• As noted below, if using python3.5+ the @ operator works as you'd expect:

  >>> print(a @ b)
  array([16, 6, 8])
  

• If you want overkill, you can use numpy.einsum. The documentation will give you a flavor for how it works, but honestly, I didn't fully understand how to use it until reading this answer and just playing around with it on my own.

  >>> np.einsum('ji,i->j', a, b)
  array([16, 6, 8])
  

• As of mid 2016 (numpy 1.10.1), you can try the experimental numpy.matmul, which works like numpy.dot with two major exceptions: no scalar multiplication but it works with stacks of matrices.

  >>> np.matmul(a, b)
  array([16, 6, 8])
  

• numpy.inner functions the same way as numpy.dot for matrix-vector multiplication but behaves differently for matrix-matrix and tensor multiplication (see Wikipedia regarding the differences between the inner product and dot product in general or see this SO answer regarding numpy's implementations).

  >>> np.inner(a, b)
  array([16, 6, 8])
  
  # Beware using for matrix-matrix multiplication though!
  >>> b = a.T
  >>> np.dot(a, b)
  array([[35,  9, 10],
         [ 9,  3,  4],
         [10,  4,  6]])
  >>> np.inner(a, b) 
  array([[29, 12, 19],
         [ 7,  4,  5],
         [ 8,  5,  6]])
  

Rarer options for edge cases

• If you have tensors (arrays of dimension greater than or equal to one), you can use numpy.tensordot with the optional argument axes=1:

  >>> np.tensordot(a, b, axes=1)
  array([16,  6,  8])
  

• Don't use numpy.vdot if you have a matrix of complex numbers, as the matrix will be flattened to a 1D array, then it will try to find the complex conjugate dot product between your flattened matrix and vector (which will fail due to a size mismatch n*m vs n).

You want to set its 'Format' property to be time and add a spin button control to it:

yourDateTimeControl.Format = DateTimePickerFormat.Time;
yourDateTimeControl.ShowUpDown = true;

Since the existing answers were written, Xcode's interface has been updated and they're no longer correct (notably the Click on Window, Organiser // Expand the Teams section step). Now the instructions for importing an existing certificate are as follows:

To export selected certificates

1. Choose Xcode > Preferences.
2. Click Accounts at the top of the window.
3. Select the team you want to view, and click View Details.
4. Control-click the certificate you want to export in the Signing Identities table and choose Export from the pop-up menu.

5. Enter a filename in the Save As field and a password in both the Password and Verify fields. The file is encrypted and password protected.
6. Click Save. The file is saved to the location you specified with a .p12 extension.

Source (Apple's documentation)

To import it, I found that Xcode's let-me-help-you menu didn't recognise the .p12 file. Instead, I simply imported it manually into Keychain, then Xcode built and archived without complaining.

array_walk() can be used with trim() to trim array

<?php
function trim_value(&$value) 
{ 
    $value = trim($value); 
}

$fruit = array('apple','banana ', ' cranberry ');
var_dump($fruit);

array_walk($fruit, 'trim_value');
var_dump($fruit);

?>

See 2nd example at http://www.php.net/manual/en/function.trim.php

Adding a space before the EOF delimiter allows to avoid cmd:

- shell: |
    cat <<' EOF'
    This is a test.

Transition is more like an animation.

div.sicon a {
    background:-moz-radial-gradient(left, #ffffff 24%, #cba334 88%);
    transition: background 0.5s linear;
    -moz-transition: background 0.5s linear; /* Firefox 4 */
    -webkit-transition: background 0.5s linear; /* Safari and Chrome */
    -o-transition: background 0.5s linear; /* Opera */
    -ms-transition: background 0.5s linear; /* Explorer 10 */
}

So you need to invoke that animation with an action.

div.sicon a:hover {
    background:-moz-radial-gradient(left, #cba334 24%, #ffffff 88%);
}

Also check for browser support and if you still have some problem with whatever you're trying to do! Check css-overrides in your stylesheet and also check out for behavior: ***.htc css hacks.. there may be something overriding your transition!

I have met the same problem. My project is running on the local server. I checked my php code.

$db = mysqli_connect('localhost', 'root', 'root', 'smart');

I use localhost to connect to my local database. That maybe the cause of the problem which you're describing. You can modify your HOSTS file. Add the line

127.0.0.1 localhost.

You need to put the entire ternary expression in parenthesis. Unfortunately that means you can't use "@:", but you could do something like this:

@(deletedView ? "Deleted" : "Created by")

Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set.

Make sure your JSON file does not have any trailing characters before or after. Maybe an unprintable one? You may want to try this way:

From the respective W3 specifications —which happen to be pretty unclear due to a lack of context— one can deduce the following:

• word-break: break-all is for breaking up foreign, non-CJK (say Western) words in CJK (Chinese, Japanese or Korean) character writings.
• word-wrap: break-word is for word breaking in a non-mixed (let us say solely Western) language.

At least, these were W3's intentions. What actually happened was a major cock-up with browser incompatibilities as a result. Here is an excellent write-up of the various problems involved.

The following code snippet may serve as a summary of how to achieve word wrapping using CSS in a cross browser environment:

-ms-word-break: break-all;
 word-break: break-all;

 /* Non standard for webkit */
 word-break: break-word;

-webkit-hyphens: auto;
   -moz-hyphens: auto;
    -ms-hyphens: auto;
        hyphens: auto;

maybe I'd go by this.

 SQL = SELECT REPLACE(myColumn, '""', '\'') FROM myTable

I used singlequotes because that's the one that registers string expressions in MySQL, or so I believe.

Hope that helps.

& is bitwise AND operator comparing bits of each operand.
For example,

int a = 4;
int b = 7;
System.out.println(a & b); // prints 4
//meaning in an 32 bit system
// 00000000 00000000 00000000 00000100
// 00000000 00000000 00000000 00000111
// ===================================
// 00000000 00000000 00000000 00000100

&& is logical AND operator comparing boolean values of operands only. It takes two operands indicating a boolean value and makes a lazy evaluation on them.

 <script type="text/javascript">     
   $("#textFileID").html("Loading...").load("URL TEXT");
 </script>  

 <div id="textFileID"></div>

$q->where("a = 1")
  ->andWhere("b = 1 OR b = 2")
  ->andWhere("c = 2 OR c = 2")
  ;

String coolString = "cool string";

byte[] byteArray = coolString.getBytes();

String reconstitutedString = new String(byteArray);

System.out.println(reconstitutedString);

That outputs "cool string" to the console.

It's pretty darn easy.

2 methods,

1. You can check usage about snippet using help()
2. you can check hidden code for those modules using inspect

1) inspect:

use inpsect module to explore code you want... NOTE: you can able to explore code only for modules (aka) packages you have imported

for eg:

  >>> import randint  
  >>> from inspect import getsource
  >>> getsource(randint) # here i am going to explore code for package called `randint`

2) help():

you can simply use help() command to get help about builtin functions as well its code.

for eg: if you want to see the code for str() , simply type - help(str)

it will return like this,

>>> help(str)
Help on class str in module __builtin__:

class str(basestring)
 |  str(object='') -> string
 |
 |  Return a nice string representation of the object.
 |  If the argument is a string, the return value is the same object.
 |
 |  Method resolution order:
 |      str
 |      basestring
 |      object
 |
 |  Methods defined here:
 |
 |  __add__(...)
 |      x.__add__(y) <==> x+y
 |
 |  __contains__(...)
 |      x.__contains__(y) <==> y in x
 |
 |  __eq__(...)
 |      x.__eq__(y) <==> x==y
 |
 |  __format__(...)
 |      S.__format__(format_spec) -> string
 |
 |      Return a formatted version of S as described by format_spec.
 |
 |  __ge__(...)
 |      x.__ge__(y) <==> x>=y
 |
 |  __getattribute__(...)

Variations on a theme:

NSString *varying = @"whatever it is";
NSString *final = [NSString stringWithFormat:@"first part %@ third part", varying];

NSString *varying = @"whatever it is";
NSString *final = [[@"first part" stringByAppendingString:varying] stringByAppendingString:@"second part"];

NSMutableString *final = [NSMutableString stringWithString:@"first part"];
[final appendFormat:@"%@ third part", varying];

NSMutableString *final = [NSMutableString stringWithString:@"first part"];
[final appendString:varying];
[final appendString:@"third part"];

Create a dummy DOM element and add the string to it. Then, you can manipulate it like any DOM element.

var el = document.createElement( 'html' );
el.innerHTML = "<html><head><title>titleTest</title></head><body><a href='test0'>test01</a><a href='test1'>test02</a><a href='test2'>test03</a></body></html>";

el.getElementsByTagName( 'a' ); // Live NodeList of your anchor elements

Edit: adding a jQuery answer to please the fans!

var el = $( '<div></div>' );
el.html("<html><head><title>titleTest</title></head><body><a href='test0'>test01</a><a href='test1'>test02</a><a href='test2'>test03</a></body></html>");

$('a', el) // All the anchor elements

Try this

view.requestLayout();

If your Activity extends ListActivity, you can simply override the OnListItemClick() method like so:

/** {@inheritDoc} */
@Override  
protected void onListItemClick(ListView l, View v, int pos, long id) {  
    super.onListItemClick(l, v, pos, id);

    // TODO : Logic
}

You can use setTargetFragment on Dialog before showing, and in dialog you can call getTargetFragment to get the reference.

You have to add Imports System.Runtime.InteropServices to the top of your source file.

Alternatively, you can fully qualify attribute name:

<System.Runtime.InteropService.DllImport("user32.dll", _
    SetLastError:=True, CharSet:=CharSet.Auto)> _

You try and compare pointers here, not the contents of what is pointed to (ie, your characters).

You must use either memcmp or str{,n}cmp to compare the contents.

    strSql = "SELECT Count(*) FROM mytable;"
    cn.Open strConnection
    Set rs = cn.Execute(strSql)
    MsgBox rs.Fields(0) & " rows in MyTable"

    rs.Close
    Set rs = Nothing

To make it short:

Node.js is well suited for applications that have a lot of concurrent connections and each request only needs very few CPU cycles, because the event loop (with all the other clients) is blocked during execution of a function.

A good article about the event loop in Node.js is Mixu's tech blog: Understanding the node.js event loop.

Just a note, on Linux You can simply run sudo su - postgres to become the postgres user and from there change what required using psql.

It's not really a function, but it is an localised piece of code. Of course it doesn't pass the code just the result. It won't work if passed to an event dispatcher to be run at a later time (as the result is calculated now and not when the event occurs). But it does localise your code into one place if that is all you are trying to do.

#include <stdio.h>

int IncMultInt(int a, int b)
{
    a++;
    return a * b;
}

int main(int argc, char *argv[])

{
    int a = 5;
    int b = 7;

    printf("%d * %d = %d\n", a, b, IncMultInt(a, b));

    b = 9;

    // Create some local code with it's own local variable
    printf("%d * %d = %d\n", a, b,  ( { int _a = a+1; _a * b; } ) );

    return 0;
}

For a complete overview of your Spark environment and configuration I found the following code snippets useful:

SparkContext:

for item in sorted(sc._conf.getAll()): print(item)

Hadoop Configuration:

hadoopConf = {}
iterator = sc._jsc.hadoopConfiguration().iterator()
while iterator.hasNext():
    prop = iterator.next()
    hadoopConf[prop.getKey()] = prop.getValue()
for item in sorted(hadoopConf.items()): print(item)

Environment variables:

import os
for item in sorted(os.environ.items()): print(item)

This can happen when you added Core Data to an existing project.

What you want to do is a combination of part of 1 and all of 2.

You need to use the PowerMockito.mockStatic to enable static mocking for all static methods of a class. This means make it possible to stub them using the when-thenReturn syntax.

But the 2-argument overload of mockStatic you are using supplies a default strategy for what Mockito/PowerMock should do when you call a method you haven't explicitly stubbed on the mock instance.

From the javadoc:

Creates class mock with a specified strategy for its answers to interactions. It's quite advanced feature and typically you don't need it to write decent tests. However it can be helpful when working with legacy systems. It is the default answer so it will be used only when you don't stub the method call.

The default default stubbing strategy is to just return null, 0 or false for object, number and boolean valued methods. By using the 2-arg overload, you're saying "No, no, no, by default use this Answer subclass' answer method to get a default value. It returns a Long, so if you have static methods which return something incompatible with Long, there is a problem.

Instead, use the 1-arg version of mockStatic to enable stubbing of static methods, then use when-thenReturn to specify what to do for a particular method. For example:

import static org.mockito.Mockito.*;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

class ClassWithStatics {
  public static String getString() {
    return "String";
  }

  public static int getInt() {
    return 1;
  }
}

@RunWith(PowerMockRunner.class)
@PrepareForTest(ClassWithStatics.class)
public class StubJustOneStatic {
  @Test
  public void test() {
    PowerMockito.mockStatic(ClassWithStatics.class);

    when(ClassWithStatics.getString()).thenReturn("Hello!");

    System.out.println("String: " + ClassWithStatics.getString());
    System.out.println("Int: " + ClassWithStatics.getInt());
  }
}

The String-valued static method is stubbed to return "Hello!", while the int-valued static method uses the default stubbing, returning 0.

In the crop class, place the image size that you want to appear:

.crop {
    width: 282px;
    height: 282px;
    overflow: hidden;
}
.crop span.img {
    background-position: center;
    background-size: cover;
    height: 282px;
    display: block;
}

The html will look like:

<div class="crop">
    <span class="img" style="background-image:url('http://url.to.image/image.jpg');"></span>
</div>

Try accessing the placeholder attribute of the input and change its value like the following:

$('#some_input_id').attr('placeholder','New Text Here');

Can also clear the placeholder if required like:

$('#some_input_id').attr('placeholder','');

Ryan Farley has a great post about this in his blog, including all the reasons why not to write back into web.config files: Writing to Your .NET Application's Config File

While @Gulzar Nazim's answer is great, it is probably easier to include the database name in the query, which could be achieved by the following SQL.

SELECT COLUMN_NAME, *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'you-table-name' AND TABLE_CATALOG='your-database-name'

Ok found out the Tomcat file server.xml must be configured as well for the data source to work. So just add:

<Resource 
auth="Container" 
driverClassName="org.apache.derby.jdbc.EmbeddedDriver" 
maxActive="20" 
maxIdle="10" 
maxWait="-1" 
name="ds/flexeraDS" 
type="javax.sql.DataSource" 
url="jdbc:derby:flexeraDB;create=true" 
  />

Have you tried the =DateValue() function?

To include time value, just add the functions together:

=DateValue(A1)+TimeValue(A1)

This question has been answered sufficiently many times, but with C# 7.2 and the introduction of the Span type, there is a faster way to do this in unsafe code:

public static class StringSupport
{
    private static readonly int _charSize = sizeof(char);

    public static unsafe byte[] GetBytes(string str)
    {
        if (str == null) throw new ArgumentNullException(nameof(str));
        if (str.Length == 0) return new byte[0];

        fixed (char* p = str)
        {
            return new Span<byte>(p, str.Length * _charSize).ToArray();
        }
    }

    public static unsafe string GetString(byte[] bytes)
    {
        if (bytes == null) throw new ArgumentNullException(nameof(bytes));
        if (bytes.Length % _charSize != 0) throw new ArgumentException($"Invalid {nameof(bytes)} length");
        if (bytes.Length == 0) return string.Empty;

        fixed (byte* p = bytes)
        {
            return new string(new Span<char>(p, bytes.Length / _charSize));
        }
    }
}

Keep in mind that the bytes represent a UTF-16 encoded string (called "Unicode" in C# land).

Some quick benchmarking shows that the above methods are roughly 5x faster than their Encoding.Unicode.GetBytes(...)/GetString(...) implementations for medium sized strings (30-50 chars), and even faster for larger strings. These methods also seem to be faster than using pointers with Marshal.Copy(..) or Buffer.MemoryCopy(...).

1. You need to make sure that sanitize.js is loaded. For example, load it from https://ajax.googleapis.com/ajax/libs/angularjs/[LAST_VERSION]/angular-sanitize.min.js
2. you need to include ngSanitize module on your app eg: var app = angular.module('myApp', ['ngSanitize']);
3. you just need to bind with ng-bind-html the original html content. No need to do anything else in your controller. The parsing and conversion is automatically done by the ngBindHtml directive. (Read the How does it work section on this: $sce). So, in your case <div ng-bind-html="preview_data.preview.embed.html"></div> would do the work.

Dim text As String = "123.45"
Dim value As Double
If Double.TryParse(text, value) Then
    ' text is convertible to Double, and value contains the Double value now
Else
    ' Cannot convert text to Double
End If

If it works fine on your local environment, probably your remote server's IP is being blocked by the server at the target URL you've set for cURL to use. You need to verify that your remote server is allowed to access the URL you've set for CURLOPT_URL.

This should do it, let me know if you have trouble with it:

Sub foo()
Dim x As Workbook
Dim y As Workbook

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Now, copy what you want from x:
x.Sheets("name of copying sheet").Range("A1").Copy

'Now, paste to y worksheet:
y.Sheets("sheetname").Range("A1").PasteSpecial

'Close x:
x.Close

End Sub

Alternatively, you could just:

Sub foo2()
Dim x As Workbook
Dim y As Workbook

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Now, transfer values from x to y:
y.Sheets("sheetname").Range("A1").Value = x.Sheets("name of copying sheet").Range("A1") 

'Close x:
x.Close

End Sub

To extend this to the entire sheet:

With x.Sheets("name of copying sheet").UsedRange
    'Now, paste to y worksheet:
    y.Sheets("sheet name").Range("A1").Resize( _
        .Rows.Count, .Columns.Count) = .Value
End With

And yet another way, store the value as a variable and write the variable to the destination:

Sub foo3()
Dim x As Workbook
Dim y As Workbook
Dim vals as Variant

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Store the value in a variable:
vals = x.Sheets("name of sheet").Range("A1").Value

'Use the variable to assign a value to the other file/sheet:
y.Sheets("sheetname").Range("A1").Value = vals 

'Close x:
x.Close

End Sub

The last method above is usually the fastest for most applications, but do note that for very large datasets (100k rows) it's observed that the Clipboard actually outperforms the array dump:

Copy/PasteSpecial vs Range.Value = Range.Value

That said, there are other considerations than just speed, and it may be the case that the performance hit on a large dataset is worth the tradeoff, to avoid interacting with the Clipboard.

Perhaps the two most efficient ways to find the last index:

def rindex(lst, value):
    lst.reverse()
    i = lst.index(value)
    lst.reverse()
    return len(lst) - i - 1

def rindex(lst, value):
    return len(lst) - operator.indexOf(reversed(lst), value) - 1

Both take only O(1) extra space and the two in-place reversals of the first solution are much faster than creating a reverse copy. Let's compare it with the other solutions posted previously:

def rindex(lst, value):
    return len(lst) - lst[::-1].index(value) - 1

def rindex(lst, value):
    return len(lst) - next(i for i, val in enumerate(reversed(lst)) if val == value) - 1

Benchmark results, my solutions are the red and green ones:

This is for searching a number in a list of a million numbers. The x-axis is for the location of the searched element: 0% means it's at the start of the list, 100% means it's at the end of the list. All solutions are fastest at location 100%, with the two reversed solutions taking pretty much no time for that, the double-reverse solution taking a little time, and the reverse-copy taking a lot of time.

A closer look at the right end:

At location 100%, the reverse-copy solution and the double-reverse solution spend all their time on the reversals (index() is instant), so we see that the two in-place reversals are about seven times as fast as creating the reverse copy.

The above was with lst = list(range(1_000_000, 2_000_001)), which pretty much creates the int objects sequentially in memory, which is extremely cache-friendly. Let's do it again after shuffling the list with random.shuffle(lst) (probably less realistic, but interesting):

All got a lot slower, as expected. The reverse-copy solution suffers the most, at 100% it now takes about 32 times (!) as long as the double-reverse solution. And the enumerate-solution is now second-fastest only after location 98%.

Overall I like the operator.indexOf solution best, as it's the fastest one for the last half or quarter of all locations, which are perhaps the more interesting locations if you're actually doing rindex for something. And it's only a bit slower than the double-reverse solution in earlier locations.
