I use a similar technique to lazyload images, but can't help but notice that Javascript doesn't access the browser cache on first loading.

My example:

I have a rotating banner on my homepage with 4 images the slider wait 2 seconds, than the javascript loads the next image, waits 2 seconds, etc.

These images have unique urls that change whenever I modify them, so they get caching headers that will cache in the browser for a year.

max-age: 31536000, public

Now when I open Chrome Devtools and make sure de 'Disable cache' option is not active and load the page for the first time (after clearing the cache) all images get fetch and have a 200 status. After a full cycle of all images in the banner the network requests stop and the cached images are used.

Now when I do a regular refresh or go to a subpage and click back, the images that are in the cache seems to be ignored. I would expect to see a grey message "from disk cache" in the Network tab of Chrome devtools. In instead I see the requests pass by every two seconds with a Green status circle instead of gray, I see data being transferred, so it I get the impression the cache is not accessed at all from javascript. It simply fetches the image each time the page gets loaded.

So each request to the homepage triggers 4 requests regardless of the caching policy of the image.

Considering the above together and the new http2 standard most webservers and browsers now support, I think it's better to stop using lazyloading since http2 will load all images nearly simultaneously.

If this is a bug in Chrome Devtools it really surprises my nobody noticed this yet. ;)

If this is true, using lazyloading only increases bandwith usage.

Please correct me if I'm wrong. :)

If you need to download a folder via a Linux command try this out:

$ scp [email protected]:foobar.txt -r /some/local/directory

To point out what I had to dig out of Chris Johansen's chat with OP (linked from a reply to an answer):

git add vendor/plugins/open_flash_chart_2 # will add gitlink, content will stay untracked

git add vendor/plugins/open_flash_chart_2/ # NOTICE THE SLASH!!!!

The second form will add it without gitlink, and the contents are trackable. The .git dir is conveniently & automatically ignored. Thank you Chris!

This will fix it

.navbar .nav > li {
z-index: 10000;
}

Or like df.filter($"friend_id".isNotNull)

Hope this helps:

function array_keys_exist($searchForKeys = array(), $inArray = array()) {
    $inArrayKeys = array_keys($inArray);
    return count(array_intersect($searchForKeys, $inArrayKeys)) == count($searchForKeys); 
}

If we look at the implementation of the equalsIgnoreCase method, we find this part:

if (string == null || count != string.count) {
    return false;
}

So it will always return false if the argument is null. And this is obviously right, because the only case where it should return true is when equalsIgnoreCase was invoked on a null String, but

String nullString = null;
nullString.equalsIgnoreCase(null);

will definitely result in a NullPointerException.

So equals methods are not designed to test whether an object is null, just because you can't invoke them on null.

Marc's answer is of course the right answer. But since he mentioned the shift operators and unsafe code as an alternative. I would like to share a less common alternative. Using a struct with Explicit layout. This is similar in principal to a C/C++ union.

Here is an example of a struct that can be used to get to the component bytes of the Int32 data type and the nice thing is that it is two way, you can manipulate the byte values and see the effect on the Int.

  using System.Runtime.InteropServices;

  [StructLayout(LayoutKind.Explicit)]
  struct Int32Converter
  {
    [FieldOffset(0)] public int Value;
    [FieldOffset(0)] public byte Byte1;
    [FieldOffset(1)] public byte Byte2;
    [FieldOffset(2)] public byte Byte3;
    [FieldOffset(3)] public byte Byte4;

    public Int32Converter(int value)
    {
      Byte1 = Byte2 = Byte3 = Byte4 = 0;
      Value = value;
    }

    public static implicit operator Int32(Int32Converter value)
    {
      return value.Value;
    }

    public static implicit operator Int32Converter(int value)
    {
      return new Int32Converter(value);
    }
  }

The above can now be used as follows

 Int32Converter i32 = 256;
 Console.WriteLine(i32.Byte1);
 Console.WriteLine(i32.Byte2);
 Console.WriteLine(i32.Byte3);
 Console.WriteLine(i32.Byte4);

 i32.Byte2 = 2;
 Console.WriteLine(i32.Value);

Of course the immutability police may not be excited about the last possiblity :)

If you're running a CentOS container, you can install ps using this command:

yum install -y procps

Running this command on Dockerfile:

RUN yum install -y procps

I tried to install a gem which is for JRuby only, running into the same error. Using jruby's command worked then:

jruby -S gem install some_jruby_gem

In case of FOREIGN KEY CONSTRAINT... there will be a problem if '0' is not present in the column of Primary key table. The solution for that is...

STEP1:

Disable all the constraints using this code :

EXEC sp_msforeachtable "ALTER TABLE ? NOCHECK CONSTRAINT all"

STEP2:

RUN UPDATE COMMAND (as mentioned in above comments)
RUN ALTER COMMAND (as mentioned in above comments)

STEP3:

Enable all the constraints using this code :

exec sp_msforeachtable @command1="print '?'", @command2="ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all"

Here is a simple example:

ThreadTest.java

public class ThreadTest
{
   public static void main(String [] args)
   {
      MyThread t1 = new MyThread(0, 3, 300);
      MyThread t2 = new MyThread(1, 3, 300);
      MyThread t3 = new MyThread(2, 3, 300);

      t1.start();
      t2.start();
      t3.start();
   }
}

MyThread.java

public class MyThread extends Thread
{
   private int startIdx, nThreads, maxIdx;

   public MyThread(int s, int n, int m)
   {
      this.startIdx = s;
      this.nThreads = n;
      this.maxIdx = m;
   }

   @Override
   public void run()
   {
      for(int i = this.startIdx; i < this.maxIdx; i += this.nThreads)
      {
         System.out.println("[ID " + this.getId() + "] " + i);
      }
   }
}

And some output:

[ID 9] 1
[ID 10] 2
[ID 8] 0
[ID 10] 5
[ID 9] 4
[ID 10] 8
[ID 8] 3
[ID 10] 11
[ID 10] 14
[ID 10] 17
[ID 10] 20
[ID 10] 23

An explanation - Each MyThread object tries to print numbers from 0 to 300, but they are only responsible for certain regions of that range. I chose to split it by indices, with each thread jumping ahead by the number of threads total. So t1 does index 0, 3, 6, 9, etc.

Now, without IO, trivial calculations like this can still look like threads are executing sequentially, which is why I just showed the first part of the output. On my computer, after this output thread with ID 10 finishes all at once, followed by 9, then 8. If you put in a wait or a yield, you can see it better:

MyThread.java

System.out.println("[ID " + this.getId() + "] " + i);
Thread.yield();

And the output:

[ID 8] 0
[ID 9] 1
[ID 10] 2
[ID 8] 3
[ID 9] 4
[ID 8] 6
[ID 10] 5
[ID 9] 7

Now you can see each thread executing, giving up control early, and the next executing.

preg_replace('/[^a-zA-Z0-9\s]/', '',$string) this is using for removing special character only rather than space between the strings.

Another example. When building a complex map of maps, the computeIfAbsent() method is a replacement for map's get() method. Through chaining of computeIfAbsent() calls together, missing containers are constructed on-the-fly by provided lambda expressions:

  // Stores regional movie ratings
  Map<String, Map<Integer, Set<String>>> regionalMovieRatings = new TreeMap<>();

  // This will throw NullPointerException!
  regionalMovieRatings.get("New York").get(5).add("Boyhood");

  // This will work
  regionalMovieRatings
    .computeIfAbsent("New York", region -> new TreeMap<>())
    .computeIfAbsent(5, rating -> new TreeSet<>())
    .add("Boyhood");

Following command connect to the remote server to dump a database:

<> optional params use them if you need them

• host - host name port
• listening port username
• username of db db
• db name ssl
• secure connection out

• output to a created folder with a name

  mongodump --host --port --username --db --ssl --password --out _date+"%Y-%m-%d"

You should use querySelectorAll. It returns NodeList, however querySelector returns only the first found element:

var deleteLink = document.querySelectorAll('.delete');

Then you would loop:

for (var i = 0; i < deleteLink.length; i++) {
    deleteLink[i].addEventListener('click', function(event) {
        if (!confirm("sure u want to delete " + this.title)) {
            event.preventDefault();
        }
    });
}

Also you should preventDefault only if confirm === false.

It's also worth noting that return false/true is only useful for event handlers bound with onclick = function() {...}. For addEventListening you should use event.preventDefault().

Demo: http://jsfiddle.net/Rc7jL/3/

ES6 version

You can make it a little cleaner (and safer closure-in-loop wise) by using Array.prototype.forEach iteration instead of for-loop:

var deleteLinks = document.querySelectorAll('.delete');

Array.from(deleteLinks).forEach(link => {
    link.addEventListener('click', function(event) {
        if (!confirm(`sure u want to delete ${this.title}`)) {
            event.preventDefault();
        }
    });
});

_{Example above uses Array.from and template strings from ES2015 standard.}

Because this is javascript and dynamic you could define your own class that matches the File interface and use that instead.

I had to do just that with dropzone.js because I wanted to simulate a file upload and it works on File objects.

Finally I got it to work. Steve's answer is right but not for all cases. It fails when that view is being executed from a third schema. For that to work you have to add the grant option:

GRANT SELECT ON [TABLE_NAME] TO [READ_USERNAME] WITH GRANT OPTION;

That way, [READ_USERNAME] can also grant select privilege over the view to another schema

You can't. The -c switch tells you when the permissions were last changed, -a tests the most recent access time, and -m tests the modification time. The filesystem used by most flavors of Linux (ext3) doesn't support a "creation time" record. Sorry!

Why could you not just make a file structure on the Windows file system and populate it with your desired names, then use a screen grabber like HyperSnap (or the ubiquitous Alt-PrtScr) to capture a section of the Explorer window.

I did this when 'demoing' an internet application which would have collapsible sections, I just had to create files that looked like my desired entries.

HyperSnap gives JPGs at least (probably others but I've never bothered to investigate).

Or you could screen capture the icons +/- from Explorer and use them within MS Word Draw itself to do your picture, but I've never been able to get MS Word Draw to behave itself properly.

You have to change the format of the date string you are supplying in order to be able to insert it using the STRFTIME function. Reason being, there is no option for a month abbreviation:

%d  day of month: 00
%f  fractional seconds: SS.SSS
%H  hour: 00-24
%j  day of year: 001-366
%J  Julian day number
%m  month: 01-12
%M  minute: 00-59
%s  seconds since 1970-01-01
%S  seconds: 00-59
%w  day of week 0-6 with sunday==0
%W  week of year: 00-53
%Y  year: 0000-9999
%%  % 

The alternative is to format the date/time into an already accepted format:

1. YYYY-MM-DD
2. YYYY-MM-DD HH:MM
3. YYYY-MM-DD HH:MM:SS
4. YYYY-MM-DD HH:MM:SS.SSS
5. YYYY-MM-DDTHH:MM
6. YYYY-MM-DDTHH:MM:SS
7. YYYY-MM-DDTHH:MM:SS.SSS
8. HH:MM
9. HH:MM:SS
10. HH:MM:SS.SSS
11. now

If you are getting the query in your output you need to show us the code that actually echos the result. Can you post the code that calls requeteSQL?

For example, if you have used single quotes in php, it will print the variable name, not the value

echo 'foo is $foo'; // foo is $foo

This sounds exactly like your problem and I am positive this is the cause.

Also, try removing the @ symbol to see if that helps by giving you more infromation.

so that

$SQL_result = @mysql_query($SQL_requete); // run the query

becomes

  $SQL_result = mysql_query($SQL_requete); // run the query

This will stop any error suppression if the query is throwing an error.

Using javascript I developed a solution. It isn't beautiful but it worked for me:

function drawMultilineText(){

    // set context and formatting   
    var context = document.getElementById("canvas").getContext('2d');
    context.font = fontStyleStr;
    context.textAlign = "center";
    context.textBaseline = "top";
    context.fillStyle = "#000000";

    // prepare textarea value to be drawn as multiline text.
    var textval = document.getElementByID("textarea").value;
    var textvalArr = toMultiLine(textval);
    var linespacing = 25;
    var startX = 0;
    var startY = 0;

    // draw each line on canvas. 
    for(var i = 0; i < textvalArr.length; i++){
        context.fillText(textvalArr[i], x, y);
        y += linespacing;
    }
}

// Creates an array where the <br/> tag splits the values.
function toMultiLine(text){
   var textArr = new Array();
   text = text.replace(/\n\r?/g, '<br/>');
   textArr = text.split("<br/>");
   return textArr;
}

Hope that helps!

You are looking for System.Reflection.Assembly.GetExecutingAssembly()

string assemblyFolder = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
string xmlFileName = Path.Combine(assemblyFolder,"AggregatorItems.xml");

Note:

The .Location property returns the location of the currently running DLL file.

Under some conditions the DLL is shadow copied before execution, and the .Location property will return the path of the copy. If you want the path of the original DLL, use the Assembly.GetExecutingAssembly().CodeBase property instead.

.CodeBase contains a prefix (file:\), which you may need to remove.

A very easy way is to use jQuery and SimpleModal plugin. Then when I need to show my "loading" gif on submit, I do:

$('*').css('cursor','wait');
$.modal("<table style='white-space: nowrap'><tr><td style='white-space: nowrap'><b>Please wait...</b></td><td><img alt='Please wait' src='loader.gif' /></td></tr></table>", {escClose:false} );

None of these answers solved my problem, which was that the items weren't the same width in my makeshift flexbox table when it was shrunk to a width too small.

The solution for me was simply to put overflow: hidden; on the flex-grow: 1; cells.

You could try using the <col> tag manage table styling for all rows but you will need to set the table-layout:fixed style on the <table> or the tables css class and set the overflow style for the cells

http://www.w3schools.com/TAGS/tag_col.asp

<table class="fixed">
    <col width="20px" />
    <col width="30px" />
    <col width="40px" />
    <tr>
        <td>text</td>
        <td>text</td>
        <td>text</td>
    </tr>
</table>

and this be your CSS

table.fixed { table-layout:fixed; }
table.fixed td { overflow: hidden; }

You may try these

 int selectedIndex = myComboBox.getSelectedIndex();

-or-

Object selectedObject = myComboBox.getSelectedItem();

-or-

String selectedValue = myComboBox.getSelectedValue().toString();

Syntax

print_r(variable, return);

variable Required. Specifies the variable to return information about

return Optional. When set to true, this function will return the information (not print it). Default is false

Example

error_log( print_r(<array Variable>, TRUE) );

Here is another way to convert Drawable resource into Bitmap in android:

Drawable drawable = getResources().getDrawable(R.drawable.input);
Bitmap bitmap = ((BitmapDrawable)drawable).getBitmap();

In windows you should use %WORKSPACE%.

In my experience calling this worked great!

handler.removeCallbacksAndMessages(null);

In the docs for removeCallbacksAndMessages it says...

Remove any pending posts of callbacks and sent messages whose obj is token. If token is null, all callbacks and messages will be removed.

Try using this attribute, for example for password min length:

[StringLength(100, ErrorMessage = "???????????? ????? ?????? 20 ????????", MinimumLength = User.PasswordMinLength)]

One way we do this in our application is using IDisposable and then with using(){} blocks to ensure the cursor is reset when done.

public class OverrideCursor : IDisposable
{

  public OverrideCursor(Cursor changeToCursor)
  {
    Mouse.OverrideCursor = changeToCursor;
  }

  #region IDisposable Members

  public void Dispose()
  {
    Mouse.OverrideCursor = null;
  }

  #endregion
}

and then in your code:

using (OverrideCursor cursor = new OverrideCursor(Cursors.Wait))
{
  // Do work...
}

The override will end when either: the end of the using statement is reached or; if an exception is thrown and control leaves the statement block before the end of the statement.

Update

To prevent the cursor flickering you can do:

public class OverrideCursor : IDisposable
{
  static Stack<Cursor> s_Stack = new Stack<Cursor>();

  public OverrideCursor(Cursor changeToCursor)
  {
    s_Stack.Push(changeToCursor);

    if (Mouse.OverrideCursor != changeToCursor)
      Mouse.OverrideCursor = changeToCursor;
  }

  public void Dispose()
  {
    s_Stack.Pop();

    Cursor cursor = s_Stack.Count > 0 ? s_Stack.Peek() : null;

    if (cursor != Mouse.OverrideCursor)
      Mouse.OverrideCursor = cursor;
  }

}

You can also use "[.]"

grep -r "0[.]49"

Use switch every time you have more than 2 conditions on a single variable, take weekdays for example, if you have a different action for every weekday you should use a switch.

Other situations (multiple variables or complex if clauses you should Ifs, but there isn't a rule on where to use each.

This work for me:

<section class="h-100">
  <header class="container h-100">
    <div class="d-flex align-items-center justify-content-center h-100">
      <div class="d-flex flex-column">
        <h1 class="text align-self-center p-2">item 1</h1>
        <h4 class="text align-self-center p-2">item 2</h4>
        <button class="btn btn-danger align-self-center p-2" type="button" name="button">item 3</button>
      </div>
    </div>
  </header>
</section>

If you want to test the logic just don´t test it asynchronously.

For example to test this code which works on results of an asynchronous method.

public class Example {
    private Dependency dependency;

    public Example(Dependency dependency) {
        this.dependency = dependency;            
    }

    public CompletableFuture<String> someAsyncMethod(){
        return dependency.asyncMethod()
                .handle((r,ex) -> {
                    if(ex != null) {
                        return "got exception";
                    } else {
                        return r.toString();
                    }
                });
    }
}

public class Dependency {
    public CompletableFuture<Integer> asyncMethod() {
        // do some async stuff       
    }
}

In the test mock the dependency with synchronous implementation. The unit test is completely synchronous and runs in 150ms.

public class DependencyTest {
    private Example sut;
    private Dependency dependency;

    public void setup() {
        dependency = Mockito.mock(Dependency.class);;
        sut = new Example(dependency);
    }

    @Test public void success() throws InterruptedException, ExecutionException {
        when(dependency.asyncMethod()).thenReturn(CompletableFuture.completedFuture(5));

        // When
        CompletableFuture<String> result = sut.someAsyncMethod();

        // Then
        assertThat(result.isCompletedExceptionally(), is(equalTo(false)));
        String value = result.get();
        assertThat(value, is(equalTo("5")));
    }

    @Test public void failed() throws InterruptedException, ExecutionException {
        // Given
        CompletableFuture<Integer> c = new CompletableFuture<Integer>();
        c.completeExceptionally(new RuntimeException("failed"));
        when(dependency.asyncMethod()).thenReturn(c);

        // When
        CompletableFuture<String> result = sut.someAsyncMethod();

        // Then
        assertThat(result.isCompletedExceptionally(), is(equalTo(false)));
        String value = result.get();
        assertThat(value, is(equalTo("got exception")));
    }
}

You don´t test the async behaviour but you can test if the logic is correct.

I change upload method with images[] according to @Denmark.

    private function upload_files($path, $title, $files)
    {
        $config = array(
            'upload_path'   => $path,
            'allowed_types' => 'jpg|gif|png',
            'overwrite'     => 1,                       
        );

        $this->load->library('upload', $config);

        $images = array();

        foreach ($files['name'] as $key => $image) {
            $_FILES['images[]']['name']= $files['name'][$key];
            $_FILES['images[]']['type']= $files['type'][$key];
            $_FILES['images[]']['tmp_name']= $files['tmp_name'][$key];
            $_FILES['images[]']['error']= $files['error'][$key];
            $_FILES['images[]']['size']= $files['size'][$key];

            $fileName = $title .'_'. $image;

            $images[] = $fileName;

            $config['file_name'] = $fileName;

            $this->upload->initialize($config);

            if ($this->upload->do_upload('images[]')) {
                $this->upload->data();
            } else {
                return false;
            }
        }

        return $images;
    }

You could also consider:

RUN apt-get update && apt-get install -y iputils-ping

(as Contango comments: you must first run apt-get update, to avoid error with missing repository).

See "Replacing ifconfig with ip"

it is most often recommended to move forward with the command that has replaced ifconfig. That command is ip, and it does a great job of stepping in for the out-of-date ifconfig.

But as seen in "Getting a Docker container's IP address from the host", using docker inspect can be more useful depending on your use case.

This is almost like the other answer but you don't need a scatter plot at all, you can simply specify a scatter-plot-like format (fmt-parameter) for errorbar:

import matplotlib.pyplot as plt
x = [1, 2, 3, 4]
y = [1, 4, 9, 16]
e = [0.5, 1., 1.5, 2.]
plt.errorbar(x, y, yerr=e, fmt='o')
plt.show()

Result:

A list of the avaiable fmt parameters can be found for example in the plot documentation:

character   description
'-'     solid line style
'--'    dashed line style
'-.'    dash-dot line style
':'     dotted line style
'.'     point marker
','     pixel marker
'o'     circle marker
'v'     triangle_down marker
'^'     triangle_up marker
'<'     triangle_left marker
'>'     triangle_right marker
'1'     tri_down marker
'2'     tri_up marker
'3'     tri_left marker
'4'     tri_right marker
's'     square marker
'p'     pentagon marker
'*'     star marker
'h'     hexagon1 marker
'H'     hexagon2 marker
'+'     plus marker
'x'     x marker
'D'     diamond marker
'd'     thin_diamond marker
'|'     vline marker
'_'     hline marker

I have similar issue faced and solve with following solution: my date format is: 'Fri Dec 11 2020 05:00:00 GMT+0500 (Pakistan Standard Time)'

let currentDate = moment(new Date('Fri Dec 11 2020 05:00:00 GMT+0500 (Pakistan Standard Time)').format('DD-MM-YYYY'); // 'Fri Dec 11 2020 05:00:00 GMT+0500 (Pakistan Standard Time)'

let output=(moment(currentDate).isSameOrAfter('07-12-2020'));

If you're looking for the version for windows get it from source forge: https://sourceforge.net/projects/dex2jar/

It has the d2j-dex2jar.bat file you need

I've been testing this myself, and looking at all the answers on this post and I don't think they answer this question very well. I experimented myself in order to get a good answer (code below). You CAN fire either event with both ActionListener and ItemListener 100% of the time when a state is changed in either a radio button or a check box, or any other kind of Swing item I'm assuming since it is type Object. The ONLY difference I can tell between these two listeners is the type of Event Object that gets returned with the listener is different. AND you get a better event type with a checkbox using an ItemListener as opposed to an ActionListener.

The return types of an ActionEvent and an ItemEvent will have different methods stored that may be used when an Event Type gets fired. In the code below the comments show the difference in .get methods for each Class returned Event type.

The code below sets up a simple JPanel with JRadioButtons, JCheckBoxes, and a JLabel display that changes based on button configs. I set all the RadioButtons and CheckBoxes up with both an Action Listener and an Item Listener. Then I wrote the Listener classes below with ActionListener fully commented because I tested it first in this experiment. You will notice that if you add this panel to a frame and display, all radiobuttons and checkboxes always fire regardless of the Listener type, just comment out the methods in one and try the other and vice versa.

Return Type into the implemented methods is the MAIN difference between the two. Both Listeners fire events the same way. Explained a little better in comment above is the reason a checkbox should use an ItemListener over ActionListener due to the Event type that is returned.

Set a far future absolute time:

setcookie("CookieName", "CookieValue", 2147483647);

It is better to use an absolute time than calculating it relative to the present as recommended in the accepted answer.

The maximum value compatible with 32 bits systems is:

2147483647 = 2^31 = ~year 2038

You can do:

x = re.findall('\d+', text)
result = x[0] if len(x) > 0 else ''

Note that your question isn't exactly related to regex. Rather, how do you safely find an element from an array, if it has none.

I ran into this error message today and wanted to post the resolution to my particular my case. It turns out that my problem was that one of my css files was missing a closing brace and this was causing the file to not be compiled. It may be harder to notice this if you have an automated process that sets everything up (including the asset precompile) for your production environment.

Just updating aleemb's original, much-upvoted answer with a couple of additions to the css.

We've been using the following combo:

.unselectable {
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    -o-user-select: none;
    user-select: none;
}

We got the suggestion for adding the webkit-touch entry from:
http://phonegap-tips.com/articles/essential-phonegap-css-webkit-touch-callout.html

2015 Apr: Just updating my own answer with a variation that may come in handy. If you need to make the DIV selectable/unselectable on the fly and are willing to use Modernizr, the following works neatly in javascript:

    var userSelectProp = Modernizr.prefixed('userSelect');
    var specialDiv = document.querySelector('#specialDiv');
    specialDiv.style[userSelectProp] = 'none';

That depends on the nature of the information you want to return.

If it is a single integer value, you can use the return statement

 create proc myproc
 as 
 begin
     return 1
 end
 go
 declare @i int
 exec @i = myproc

If you have a non integer value, or a number of scalar values, you can use output parameters

create proc myproc
  @a int output,
  @b varchar(50) output
as
begin
  select @a = 1, @b='hello'
end
go
declare @i int, @j varchar(50)
exec myproc @i output, @j output

If you want to return a dataset, you can use insert exec

create proc myproc
as 
begin
     select name from sysobjects
end
go

declare @t table (name varchar(100))
insert @t (name)
exec myproc

You can even return a cursor but that's just horrid so I shan't give an example :)

Use a regular expression to catch the id number and replace the whole line with the number. Something like this should do it (match everything up to "id=", then match any number of digits, then match the rest of the line):

sed -e 's/.*id=\([0-9]\+\).*/\1/g'

Do this for every line and you get the list of ids.

To make images adjustable/flexible you could use this:

/* fit images to container */
.container img {
    max-width: 100%;
    height: auto;
}

You obviously use mutex to lock a data in one thread getting accessed by another thread at the same time. Assume that you have just called lock() and in the process of accessing data. This means that you don’t expect any other thread (or another instance of the same thread-code) to access the same data locked by the same mutex. That is, if it is the same thread-code getting executed on a different thread instance, hits the lock, then the lock() should block the control flow there. This applies to a thread that uses a different thread-code, which is also accessing the same data and which is also locked by the same mutex. In this case, you are still in the process of accessing the data and you may take, say, another 15 secs to reach the mutex unlock (so that the other thread that is getting blocked in mutex lock would unblock and would allow the control to access the data). Do you at any cost allow yet another thread to just unlock the same mutex, and in turn, allow the thread that is already waiting (blocking) in the mutex lock to unblock and access the data? Hope you got what I am saying here? As per, agreed upon universal definition!,

• with “mutex” this can’t happen. No other thread can unlock the lock in your thread
• with “binary-semaphore” this can happen. Any other thread can unlock the lock in your thread

So, if you are very particular about using binary-semaphore instead of mutex, then you should be very careful in “scoping” the locks and unlocks. I mean that every control-flow that hits every lock should hit an unlock call, also there shouldn’t be any “first unlock”, rather it should be always “first lock”.

When converting SVG to transparent PNG, don't forget to put this BEFORE $imagick->readImageBlob():

$imagick->setBackgroundColor(new ImagickPixel('transparent'));

You have System.out.println("Scanning...") in a catch block. Do you want to put that in try?

Josh Bloch favors your approach:

The reason that I favor the instanceof approach is that when you use the getClass approach, you have the restriction that objects are only equal to other objects of the same class, the same run time type. If you extend a class and add a couple of innocuous methods to it, then check to see whether some object of the subclass is equal to an object of the super class, even if the objects are equal in all important aspects, you will get the surprising answer that they aren't equal. In fact, this violates a strict interpretation of the Liskov substitution principle, and can lead to very surprising behavior. In Java, it's particularly important because most of the collections (HashTable, etc.) are based on the equals method. If you put a member of the super class in a hash table as the key and then look it up using a subclass instance, you won't find it, because they are not equal.

See also this SO answer.

Effective Java chapter 3 also covers this.

This is probably unlikely, but given that your observed behaviour is unusual it needs to be checked and no-one else has mentioned it.

Are you absolutely sure that all objects are owned by dbo and you don't have a rogue copies owned by yourself or a different user present as well?

Just occasionally when I've seen odd behaviour it's because there was actually two copies of an object and which one you get depends on what is specified and who you are logged on as. For example it is perfectly possible to have two copies of a view or procedure with the same name but owned by different owners - a situation that can arise where you are not logged onto the database as a dbo and forget to specify dbo as object owner when you create the object.

In note that in the text you are running some things without specifying owner, eg

sp_recompile ViewOpener

if for example there where two copies of viewOpener present owned by dbo and [some other user] then which one you actually recompile if you don't specify is dependent upon circumstances. Ditto with the Report_Opener view - if there where two copies (and they could differ in specification or execution plan) then what is used depends upon circumstances - and as you do not specify owner it is perfectly possible that your adhoc query might use one and the compiled procedure might use use the other.

As I say, it's probably unlikely but it is possible and should be checked because your issues could be that you're simply looking for the bug in the wrong place.

If state of a method is not supposed to be changed or its not going to use any instance variables.

You want to call method without instance.

If it only works on arguments provided to it.

Utility functions are good instance of static methods. i.e math.pow(), this function is not going to change the state for different values. So it is static.

I run into this, it's an old question, but I want that file to be tracked but to not track it on certain working copies, to do that you can run

git update-index --assume-unchanged sites/default/settings.php

Use String.matches(), like:

String myString = "qwerty123456";
System.out.println(myString.matches("[A-Za-z0-9]+"));

That may not be the absolute "fastest" possible approach. But in general there's not much point in trying to compete with the people who write the language's "standard library" in terms of performance.

You can also use psql console to execute \copy without need to send file to Postgresql server machine. The command is the same:

\copy mytable [ ( column_list ) ] FROM '/path/to/csv/file' WITH CSV HEADER

The below code illustrates how using a generator returns a result before completion, unlike the traditional non generator approach that returns a complete array after full iteration. With the generator below, the values are returned when ready, no need to wait for an array to be completely filled:

<?php 

function sleepiterate($length) {
    for ($i=0; $i < $length; $i++) {
        sleep(2);
        yield $i;
    }
}

foreach (sleepiterate(5) as $i) {
    echo $i, PHP_EOL;
}

unique_ptr
is a smart pointer which owns an object exclusively.

shared_ptr
is a smart pointer for shared ownership. It is both copyable and movable. Multiple smart pointer instances can own the same resource. As soon as the last smart pointer owning the resource goes out of scope, the resource will be freed.

You should remember that shell scripting is less of a language and more of a collection of commands. Instinctively you think that this "language" requires you to follow an if with a [ or a [[. Both of those are just commands that return an exit status indicating success or failure (just like every other command). For that reason I'd use grep, and not the [ command.

Just do:

if grep -q foo <<<"$string"; then
    echo "It's there"
fi

Now that you are thinking of if as testing the exit status of the command that follows it (complete with semi-colon), why not reconsider the source of the string you are testing?

## Instead of this
filetype="$(file -b "$1")"
if grep -q "tar archive" <<<"$filetype"; then
#...

## Simply do this
if file -b "$1" | grep -q "tar archive"; then
#...

The -q option makes grep not output anything, as we only want the return code. <<< makes the shell expand the next word and use it as the input to the command, a one-line version of the << here document (I'm not sure whether this is standard or a Bashism).

You can also get the number of data by using the count function.

$query = $this->dm->createQueryBuilder('AppBundle:Items')
                    ->field('isDeleted')->equals(false)
                    ->getQuery()->count();

It checks whether the page has been called through POST (as opposed to GET, HEAD, etc). When you type a URL in the menu bar, the page is called through GET. However, when you submit a form with method="post" the action page is called with POST.

Who is Jon Skeet?

We request that the developer asking for the pull request state that they would like the branch deleted. Most of the time this is the case. There are times when a branch is needed (e.g. copying the changes to another release branch).

My fingers have memorized our process:

git checkout <feature-branch>
git pull
git checkout <release-branch>
git pull
git merge --no-ff <feature-branch>
git push
git tag -a branch-<feature-branch> -m "Merge <feature-branch> into <release-branch>"
git push --tags
git branch -d <feature-branch>
git push origin :<feature-branch>

A branch is for work. A tag marks a place in time. By tagging each branch merge we can resurrect a branch if that is needed. The branch tags have been used several times to review changes.

Your command is wrong.

Linux

java -- version

macOS

java -version

You can't use those commands other way around.

To find a very long list of words in big files, it can be more efficient to use egrep:

remove the last \n of A
$ tr '\n' '|' < A > A_regex
$ egrep -f A_regex B

Have in mind that clone() doesn't work out of the box. You will have to implement Cloneable and override the clone() method making in public.

There are a few alternatives, which are preferable (since the clone() method has lots of design issues, as stated in other answers), and the copy-constructor would require manual work:

• BeanUtils.cloneBean(original) creates a shallow clone, like the one created by Object.clone(). (this class is from commons-beanutils)

• SerializationUtils.clone(original) creates a deep clone. (i.e. the whole properties graph is cloned, not only the first level) (from commons-lang), but all classes must implement Serializable

• Java Deep Cloning Library offers deep cloning without the need to implement Serializable

For making a CORS request one must add headers to the request along with the same he needs to check of mode_header is enabled in Apache.

For enabling headers in Ubuntu:

sudo a2enmod headers

For php server to accept request from different origin use:

Header set Access-Control-Allow-Origin *
Header set Access-Control-Allow-Methods "GET, POST, PUT, DELETE"
Header always set Access-Control-Allow-Headers "x-requested-with, Content-Type, origin, authorization, accept, client-security-token"

I understand that you want the Widget2 sharing the bottom border with the contents div. Try adding

style="position: relative; bottom: 0px"

to your Widget2 tag. Also try:

style="position: absolute; bottom: 0px"

if you want to snap your widget to the bottom of the screen.

I am a little rusty with CSS, perhaps the correct style is "margin-bottom: 0px" instead "bottom: 0px", give it a try. Also the pull-right class seems to add a "float=right" style to the element, and I am not sure how this behaves with "position: relative" and "position: absolute", I would remove it.

Use jq -s add:

$ echo '{"a":"foo","b":"bar"} {"c":"baz","a":0}' | jq -s add
{
  "a": 0,
  "b": "bar",
  "c": "baz"
}

This reads all JSON texts from stdin into an array (jq -s does that) then it "reduces" them.

(add is defined as def add: reduce .[] as $x (null; . + $x);, which iterates over the input array's/object's values and adds them. Object addition == merge.)

It's been quite a few years since this question was last answered. React introduced "Hooks" back in 2017, and "keyCode" has been deprecated.

Now we can write this:

  useEffect(() => {
    const listener = event => {
      if (event.code === "Enter" || event.code === "NumpadEnter") {
        console.log("Enter key was pressed. Run your function.");
        // callMyFunction();
      }
    };
    document.addEventListener("keydown", listener);
    return () => {
      document.removeEventListener("keydown", listener);
    };
  }, []);

This registers a listener on the keydown event, when the component is loaded for the first time. It removes the event listener when the component is destroyed.

Yup, As @luizfelippe mentioned Session class has been removed since SDK 4.0. We need to use LoginManager.

I just looked into LoginButton class for logout. They are making this kind of check. They logs out only if accessToken is not null. So, I think its better to have this in our code too..

AccessToken accessToken = AccessToken.getCurrentAccessToken();
if(accessToken != null){
    LoginManager.getInstance().logOut();
}

In MySQL , DESCRIBE table_name

In PostgreSQL , \d table_name

        a.attname AS Field,
        t.typname || '(' || a.atttypmod || ')' AS Type,
        CASE WHEN a.attnotnull = 't' THEN 'YES' ELSE 'NO' END AS Null,
        CASE WHEN r.contype = 'p' THEN 'PRI' ELSE '' END AS Key,
        (SELECT substring(pg_catalog.pg_get_expr(d.adbin, d.adrelid), '\'(.*)\'')

2. implementation 'com.google.code.gson:gson:2.8.5' -> adding gson for JSON data manipulation in android.

Unlike languages such as C, a Python variable is in scope for the whole of the function (or class, or module) where it appears, not just in the innermost "block". It is as though you declared int x at the top of the function (or class, or module), except that in Python you don't have to declare variables.

Note that the existence of the variable x is checked only at runtime -- that is, when you get to the print x statement. If __name__ didn't equal "__main__" then you would get an exception: NameError: name 'x' is not defined.

If you really want a vba solution you can loop through a range like this:

Sub Check()
    Dim dat As Variant
    Dim rng As Range
    Dim i As Long

    Set rng = Range("A1:A100")
    dat = rng
    For i = LBound(dat, 1) To UBound(dat, 1)
        If dat(i, 1) <> "" Then
            rng(i, 2).Value = "My Text"
        End If
    Next
End Sub

*EDIT*

Instead of using varients you can just loop through the range like this:

Sub Check()
    Dim rng As Range
    Dim i As Long

    'Set the range in column A you want to loop through
    Set rng = Range("A1:A100")
    For Each cell In rng
        'test if cell is empty
        If cell.Value <> "" Then
            'write to adjacent cell
            cell.Offset(0, 1).Value = "My Text"
        End If
    Next
End Sub

To static either a row or a column, put a $ sign in front of it. So if you were to use the formula =AVERAGE($A1,$C1) and drag it down the entire sheet, A and C would remain static while the 1 would change to the current row

If you're on Windows, you can achieve the same thing by repeatedly pressing F4 while in the formula editing bar. The first F4 press will static both (it will turn A1 into $A$1), then just the row (A$1) then just the column ($A1)

Although technically with the formulas that you have, dragging down for the entirety of the column shouldn't be a problem without putting a $ sign in front of the column. Setting the column as static would only come into play if you're dragging ACROSS columns and want to keep using the same column, and setting the row as static would be for dragging down rows but wanting to use the same row.

one way to do this would be to use indexing with .loc.

Example

In the absence of an example dataframe, I'll make one up here:

import numpy as np
import pandas as pd

df = pd.DataFrame({'c1': list('abcdefg')})
df.loc[5, 'c1'] = 'Value'

>>> df
      c1
0      a
1      b
2      c
3      d
4      e
5  Value
6      g

Assuming you wanted to create a new column c2, equivalent to c1 except where c1 is Value, in which case, you would like to assign it to 10:

First, you could create a new column c2, and set it to equivalent as c1, using one of the following two lines (they essentially do the same thing):

df = df.assign(c2 = df['c1'])
# OR:
df['c2'] = df['c1']

Then, find all the indices where c1 is equal to 'Value' using .loc, and assign your desired value in c2 at those indices:

df.loc[df['c1'] == 'Value', 'c2'] = 10

And you end up with this:

>>> df
      c1  c2
0      a   a
1      b   b
2      c   c
3      d   d
4      e   e
5  Value  10
6      g   g

If, as you suggested in your question, you would perhaps sometimes just want to replace the values in the column you already have, rather than create a new column, then just skip the column creation, and do the following:

df['c1'].loc[df['c1'] == 'Value'] = 10
# or:
df.loc[df['c1'] == 'Value', 'c1'] = 10

Giving you:

>>> df
      c1
0      a
1      b
2      c
3      d
4      e
5     10
6      g

It does support input/output parameters (including RETURN value) if you use DynamicParameters, but in this case the simpler option is simply:

var id = connection.QuerySingle<int>( @"
INSERT INTO [MyTable] ([Stuff]) VALUES (@Stuff);
SELECT CAST(SCOPE_IDENTITY() as int)", new { Stuff = mystuff});

Note that on more recent versions of SQL Server you can use the OUTPUT clause:

var id = connection.QuerySingle<int>( @"
INSERT INTO [MyTable] ([Stuff])
OUTPUT INSERTED.Id
VALUES (@Stuff);", new { Stuff = mystuff});

You have to make classpath in pom file for your dependency. Therefore you have to copy all the dependencies into one place.

I experienced the same issue, same version of Chrome though it's unrelated to the issue. With the developer console I captured an instance of the request that spawned this, and it is an API call served by ad.doubleclick.net. Specifically, this resource returns a response with Content-Disposition: attachment; filename="f.txt".

The URL I happened to capture was https://ad.doubleclick.net/adj/N7412.226578.VEVO/B8463950.115078190;sz=300x60...

Per curl:

$ curl -I 'https://ad.doubleclick.net/adj/N7412.226578.VEVO/B8463950.115078190;sz=300x60;click=https://2975c.v.fwmrm.net/ad/l/1?s=b035&n=10613%3B40185%3B375600%3B383270&t=1424475157058697012&f=&r=40185&adid=9201685&reid=3674011&arid=0&auid=&cn=defaultClick&et=c&_cc=&tpos=&sr=0&cr=;ord=435266097?'

Html.Partial returns a String. Html.RenderPartial calls Write internally and returns void.

The basic usage is:

// Razor syntax
@Html.Partial("ViewName")
@{ Html.RenderPartial("ViewName");  }

// WebView syntax
<%: Html.Partial("ViewName") %>
<% Html.RenderPartial("ViewName"); %>

In the snippet above, both calls will yield the same result.

While one can store the output of Html.Partial in a variable or return it from a method, one cannot do this with Html.RenderPartial.

The result will be written to the Response stream during execution/evaluation.

This also applies to Html.Action and Html.RenderAction.

There's also the bash builtin 'expr' command:

INPUT="someletters_12345_moreleters.ext"  
SUBSTRING=`expr match "$INPUT" '.*_\([[:digit:]]*\)_.*' `  
echo $SUBSTRING

I'm not sure what vim is doing, but it is an interesting effect. The way you're describing what you want sounds more like how macros work (:help macro). Something like this would do what you want with macros (starting in normal-mode):

1. qa: Record macro to a register.
2. 0w: 0 goto start of line, w jump one word.
3. i"<Esc>: Enter insert-mode, insert a " and return to normal-mode.
4. 2e: Jump to end of second word.
5. a"<Esc>: Append a ".
6. jq Move to next line and end macro recording.

Taken together: qa0wi"<Esc>2ea"<Esc>

Now you can execute the macro with @a, repeat last macro with @@. To apply to the rest of the file, do something like 99@a which assumes you do not have more than 99 lines, macro execution will end when it reaches end of file.

Here is how to achieve what you want with visual-block-mode (starting in normal mode):

1. Navigate to where you want the first quote to be.
2. Enter visual-block-mode, select the lines you want to affect, G to go to the bottom of the file.
3. Hit I"<Esc>.
4. Move to the next spot you want to insert a ".
5. You want to repeat what you just did so a simple . will suffice.

We encountered this issue on a Tomcat running from a jre directory that was (almost fully) removed after an automatic jre update, so that the running jre could no longer find jre.../lib/security/cacerts because it no longer existed.

Restarting Tomcat (after changing the configuration to run from the different jre location) fixed the problem.

I just stumbled on this old post, and while I'm sure user01 has long since found his answer, I found the current answers don't quite work. After playing around for a little bit using info provided by the others, I found a solution that worked in IE, Firefox, and Chrome. In CSS:

html, body {
    height: 100%;
}

html {
    display: table;
    margin: auto;
}

body {
    display: table-cell;
    vertical-align: middle;
}

This is almost identical to abernier's answer, but I found that including width would break the centering, as would omitting the auto margin. I hope anyone else who stumbles on this thread will find my answer helpful.

Note: Omit html, body { height: 100%; } to only center horizontally.

If you want the executable:

System.Reflection.Assembly.GetEntryAssembly().Location

If you want the assembly that's consuming your library (which could be the same assembly as above, if your code is called directly from a class within your executable):

System.Reflection.Assembly.GetCallingAssembly().Location

If you'd like just the filename and not the path, use:

Path.GetFileName(System.Reflection.Assembly.GetEntryAssembly().Location)

In this approach only one statement is executed when the UPDATE is successful.

-- For each row in source
BEGIN TRAN    

UPDATE target
SET <target_columns> = <source_values>
WHERE <target_expression>

IF (@@ROWCOUNT = 0)
   INSERT target (<target_columns>)
VALUES (<source_values>)

COMMIT

Love VonC's answer. Here's an easy version of it for beginners.

There is a git remote called origin which I am sure you are all aware of. Basically, you can add as many remotes to a git repo as you want. So, what we can do is introduce a new remote which is the original repo not the fork. I like to call it original

Let's add original repo's to our fork as a remote.

git remote add original https://git-repo/original/original.git

Now let's fetch the original repo to make sure we have the latest coded

git fetch original

As, VonC suggested, make sure we are on the master.

git checkout master

Now to bring our fork up to speed with the latest code on original repo, all we have to do is hard reset our master branch in accordance with the original remote.

git reset --hard original/master

And you are done :)

A slight improvement building on FishBoy's suggestion.

It is possible to do this kind of query in one hit, rather than in two separate stages. i.e. the single query below will page distinct results correctly, and also return entities instead of just IDs.

Simply use a DetachedCriteria with an id projection as a subquery, and then add paging values on the main Criteria object.

It will look something like this:

DetachedCriteria idsOnlyCriteria = DetachedCriteria.forClass(MyClass.class);
//add other joins and query params here
idsOnlyCriteria.setProjection(Projections.distinct(Projections.id()));

Criteria criteria = getSession().createCriteria(myClass);
criteria.add(Subqueries.propertyIn("id", idsOnlyCriteria));
criteria.setFirstResult(0).setMaxResults(50);
return criteria.list();

The selector would be label[for=email], so in CSS:

label[for=email]
{
    /* ...definitions here... */
}

...or in JavaScript using the DOM:

var element = document.querySelector("label[for=email]");

...or in JavaScript using jQuery:

var element = $("label[for=email]");

It's an attribute selector. Note that some browsers (versions of IE < 8, for instance) may not support attribute selectors, but more recent ones do. To support older browsers like IE6 and IE7, you'd have to use a class (well, or some other structural way), sadly.

(I'm assuming that the template {t _your_email} will fill in a field with id="email". If not, use a class instead.)

Note that if the value of the attribute you're selecting doesn't fit the rules for a CSS identifier (for instance, if it has spaces or brackets in it, or starts with a digit, etc.), you need quotes around the value:

label[for="field[]"]
{
    /* ...definitions here... */
}

They can be single or double quotes.

I had this issue while trying to build my solution in TFS. We were using "dot net publish" task. Using msbuild broke the ice for us.

I was trying to write a code that would work on both Mac and Windows. The code was working fine on Windows, but was giving the response as 'Unsupported Media Type' on Mac. Here is the code I used and the following line made the code work on Mac as well:

Request.AddHeader "Content-Type", "application/json"

Here is the snippet of my code:

Dim Client As New WebClient
Dim Request As New WebRequest
Dim Response As WebResponse
Dim Distance As String

Client.BaseUrl = "http://1.1.1.1:8080/config"
Request.AddHeader "Content-Type", "application/json" *** The line that made the code work on mac

Set Response = Client.Execute(Request)

    public static int[] ConvertArray(string[] arrayToConvert)
    {
        int[] resultingArray = new int[arrayToConvert.Length];

        int itemValue;

        resultingArray = Array.ConvertAll<string, int>
            (
                arrayToConvert, 
                delegate(string intParameter) 
                {
                    int.TryParse(intParameter, out itemValue);
                    return itemValue;
                }
            );

        return resultingArray;
    }

The answer given by FelixFett worked for me. To reiterate:

<meta http-equiv="X-UA-Compatible" content="IE=11; IE=10; IE=9; IE=8; IE=7; IE=EDGE" />

I have it as the first 'meta' tag in my code. I added 10 and 11 as those are versions that are published now for Internet Explorer.

I would've just commented on his answer but I do not have a high enough reputation...

Try writing all the errors to a file.

error_reporting(-1); // reports all errors
ini_set("display_errors", "1"); // shows all errors
ini_set("log_errors", 1);
ini_set("error_log", "/tmp/php-error.log");

Something like that.

I think this has something to do with your HTM.fromHtml(subTitle) call: a "\n" doesn't mean bupkis to HTML. Try <br/> instead of "\n".

As dan_nl stated, you can add a private fake repository in package.json. You don't even need name and version for it:

{
  ...,
  "repository": {
    "private": true
  }
}

Update: This feature is undocumented and might not work. Choose the following option.

Better still: Set the private flag directly. This way npm doesn't ask for a README file either:

{
  "name": ...,
  "description": ...,
  "version": ...,
  "private": true
}

I use below sql to exclude the null string and empty string lines.

select * from table where length(nvl(column1,0))>0

Because, the length of empty string is 0.

select length('');
+-----------+--+
| length()  |
+-----------+--+
| 0         |
+-----------+--+

What about?

    input[type="text"] {
          max-width:none;
   }

Checking that some css file is causing problems. By default bootstrap displays over the entire width. For instance in MVC directory Content is site.css and there is a definition constraining width.

input,select,textarea {
max-width: 280px;}

I think the question is a bit confusing.

If you mean "can foreign key 'refer' to a primary key in the same table?", the answer is a firm yes as some replied. For example, in an employee table, a row for an employee may have a column for storing manager's employee number where the manager is also an employee and hence will have a row in the table like a row of any other employee.

If you mean "can column(or set of columns) be a primary key as well as a foreign key in the same table?", the answer, in my view, is a no; it seems meaningless. However, the following definition succeeds in SQL Server!

create table t1(c1 int not null primary key foreign key references t1(c1))

But I think it is meaningless to have such a constraint unless somebody comes up with a practical example.

AmanS, in your example d_id in no circumstance can be a primary key in Employee table. A table can have only one primary key. I hope this clears your doubt. d_id is/can be a primary key only in department table.

In php.ini search for upload_max_filesize and post_max_size. I had the same problem and the solution was to change these values to a value greater than the file size.

I think it will ok for you

var base_url = window.location.origin;

var host = window.location.host;

var pathArray = window.location.pathname.split( '/' );

I use requests package whenever I want something related to HTTP requests because its API is very easy to start with:

first, install requests

$ pip install requests

then the code:

from requests import get  # to make GET request


def download(url, file_name):
    # open in binary mode
    with open(file_name, "wb") as file:
        # get request
        response = get(url)
        # write to file
        file.write(response.content)

Works on almost all browsers.

You can try giving padding-bottom as a percentage.

<div style="height:0;width:20%;padding-bottom:20%;background-color:red">
<div>
Content goes here
</div>
</div>

The outer div is making a square and inner div contains the content. This solution worked for me many times.

Here's a jsfiddle

You could use a flag to keep track of the status:

var output = $('h1');_x000D_
var isPaused = false;_x000D_
var time = 0;_x000D_
var t = window.setInterval(function() {_x000D_
  if(!isPaused) {_x000D_
    time++;_x000D_
    output.text("Seconds: " + time);_x000D_
  }_x000D_
}, 1000);_x000D_
_x000D_
//with jquery_x000D_
$('.pause').on('click', function(e) {_x000D_
  e.preventDefault();_x000D_
  isPaused = true;_x000D_
});_x000D_
_x000D_
$('.play').on('click', function(e) {_x000D_
  e.preventDefault();_x000D_
  isPaused = false;_x000D_
});

h1 {_x000D_
    font-family: Helvetica, Verdana, sans-serif;_x000D_
    font-size: 12px;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<h1>Seconds: 0</h1>_x000D_
<button class="play">Play</button>_x000D_
<button class="pause">Pause</button>

This is just what I would do, I'm not sure if you can actually pause the setInterval.

Note: This system is easy and works pretty well for applications that don't require a high level of precision, but it won't consider the time elapsed in between ticks: if you click pause after half a second and later click play your time will be off by half a second.

npm rebuild node-sass was giving me errors (Ubuntu) and npm install gulp-sass didn't make the error go away.

Saw a solution on GitHub which worked for me:

npm uninstall --save-dev gulp-sass

npm install --save-dev gulp-sass

Yes, querySelectorAll does take a group of selectors:

form, p, legend

You can list all unreachable commits by writing this command in terminal -

git fsck --unreachable

Check unreachable commit hash -

git show hash

Finally apply if you find the stashed item -

git stash apply hash

The globals() function returns a dictionary, where keys are names of objects you can name (and values, by the way, are ids of these objects) The exec() function takes a string and executes it as if you just type it in a python console. So, the code is

for i in list(globals().keys()):
    if(i[0] != '_'):
        exec('del {}'.format(i))

I can handle this way:

select to_number(to_char(sysdate,'MI')) - to_number(to_char(*YOUR_DATA_VALUE*,'MI')),max(exp_time)  from ...

Or if you want to the hour just change the MI;

select to_number(to_char(sysdate,'HH24')) - to_number(to_char(*YOUR_DATA_VALUE*,'HH24')),max(exp_time)  from ...

the others don't work for me. Good luck.

It may be late but I came across something which explains your concern related to proxy (only 'external' method calls coming in through the proxy will be intercepted) nicely.

For example, you have a class that looks like this

@Component("mySubordinate")
public class CoreBusinessSubordinate {

    public void doSomethingBig() {
        System.out.println("I did something small");
    }

    public void doSomethingSmall(int x){
        System.out.println("I also do something small but with an int");    
  }
}

and you have an aspect, that looks like this:

@Component
@Aspect
public class CrossCuttingConcern {

    @Before("execution(* com.intertech.CoreBusinessSubordinate.*(..))")
    public void doCrossCutStuff(){
        System.out.println("Doing the cross cutting concern now");
    }
}

When you execute it like this:

 @Service
public class CoreBusinessKickOff {

    @Autowired
    CoreBusinessSubordinate subordinate;

    // getter/setters

    public void kickOff() {
       System.out.println("I do something big");
       subordinate.doSomethingBig();
       subordinate.doSomethingSmall(4);
   }

}

Results of calling kickOff above given code above.

I do something big
Doing the cross cutting concern now
I did something small
Doing the cross cutting concern now
I also do something small but with an int

but when you change your code to

@Component("mySubordinate")
public class CoreBusinessSubordinate {

    public void doSomethingBig() {
        System.out.println("I did something small");
        doSomethingSmall(4);
    }

    public void doSomethingSmall(int x){
       System.out.println("I also do something small but with an int");    
   }
}


public void kickOff() {
  System.out.println("I do something big");
   subordinate.doSomethingBig();
   //subordinate.doSomethingSmall(4);
}

You see, the method internally calls another method so it won't be intercepted and the output would look like this:

I do something big
Doing the cross cutting concern now
I did something small
I also do something small but with an int

You can by-pass this by doing that

public void doSomethingBig() {
    System.out.println("I did something small");
    //doSomethingSmall(4);
    ((CoreBusinessSubordinate) AopContext.currentProxy()).doSomethingSmall(4);
}

setup.py is Python's answer to a multi-platform installer and make file.

If you’re familiar with command line installations, then make && make install translates to python setup.py build && python setup.py install.

Some packages are pure Python, and are only byte compiled. Others may contain native code, which will require a native compiler (like gcc or cl) and a Python interfacing module (like swig or pyrex).

I've put together solutions proposed by @Cory Walker with the extensions from @Rafael and the one form @Tex witch was a bit complicated for me and came up with a solution that is hopefully

error-proof with javascript and CSS disabled.

It manipulates with the background-color of the form field to show/hide the label.

<head>

<style type="text/css">
<!--
    input {position:relative;background:transparent;} 
-->
</style>

<script>
    function labelPosition() {
        document.getElementById("name").style.position="absolute"; 
            // label is moved behind the textfield using the script, 
            // so it doesnt apply when javascript disabled
    }
</script>

</head>
<body onload="labelPosition()">

<form>
        <label id="name">Your name</label>
        <input type="text" onblur="if(this.value==''){this.style.background='transparent';}" onfocus="this.style.background='white'">
</form>

</body>

In Net Core 3.0:

I was not able to find a way to Reset Migrations.

I also ran into problems with broken migrations, and the answers provided here didn't work for me. I have a .Net Core 3.0 web API, and somewhere in the last month I edited the database directly. Yes, I did a bad, bad thing.

Strategies suggested here resulted in a number of errors in Package Manager Console:

• A migration of that name already exists
• Could not find the snapshot
• 'Force' is not a recognized parameter

Granted, I may have missed a step or missed clearing out the correct files, but I found that there are ways to clean this up without as much brute force:

• Remove-Migration from the PMC for each migration by name, in reverse order of creation, up to and including the broken migration
• Add-Migration to create a new migration which will be the delta between the last good migration up to the current schema

Now when the web API is started with an empty database, it correctly creates all the tables and properties to match the entity models.

HTH!

Percent encoding. Replace the hash with %23.

A simple jQuery plugin

This is a variation on Mahes' solution. You can call it like $('table#foo').scrollableTable();

The idea is:

• Split the thead and tbody into separate table elements
• Make their cell widths match again
• Wrap the second table in a div.scrollable
• Use CSS to make div.scrollable actually scroll

The CSS could be:

div.scrollable { height: 300px; overflow-y: scroll;}

Caveats

• Obviously, splitting up these tables makes the markup less semantic. I'm not sure what effect this has on accessibility.
• This plugin does not deal with footers, multiple headers, etc.
• I've only tested it in Chrome version 20.

That said, it works for my purposes and you're free to take and modify it.

Here's the plugin:

jQuery.fn.scrollableTable = function () {
  var $newTable, $oldTable, $scrollableDiv, originalWidths;
  $oldTable = $(this);

  // Once the tables are split, their cell widths may change. 
  // Grab these so we can make the two tables match again.
  originalWidths = $oldTable.find('tr:first td').map(function() {
    return $(this).width();
  });

  $newTable = $oldTable.clone();
  $oldTable.find('tbody').remove();
  $newTable.find('thead').remove();

  $.each([$oldTable, $newTable], function(index, $table) {
    $table.find('tr:first td').each(function(i) {
      $(this).width(originalWidths[i]);
    });
  });

  $scrollableDiv = $('<div/>').addClass('scrollable');
  $newTable.insertAfter($oldTable).wrap($scrollableDiv);
};

Yet another answer, since the person said "I don't know how many times my function will be called", you could use the vector insert method like so to append arrays of values to the end of the vector:

vector<int> x;

void AddValues(int* values, size_t size)
{
   x.insert(x.end(), values, values+size);
}

I like this way because the implementation of the vector should be able to optimize for the best way to insert the values based on the iterator type and the type itself. You are somewhat replying on the implementation of stl.

If you need to guarantee the fastest speed and you know your type is a POD type then I would recommend the resize method in Thomas's answer:

vector<int> x;

void AddValues(int* values, size_t size)
{
   size_t old_size(x.size());
   x.resize(old_size + size, 0);
   memcpy(&x[old_size], values, size * sizeof(int));
}

Unless you are already using CollectionUtils I would go for List.isEmpty(), less dependencies.

Performance wise CollectionUtils will be a tad slower. Because it basically follows the same logic but has additional overhead.

So it would be readability vs. performance vs. dependencies. Not much of a big difference though.

It goes like ng-bind-html-unsafe="opt.text":

<div ng-app ng-controller="MyCtrl">
    <ul>
    <li ng-repeat=" opt in opts" ng-bind-html-unsafe="opt.text" >
        {{ opt.text }}
    </li>
    </ul>

    <p>{{opt}}</p>
</div>

http://jsfiddle.net/gFFBa/3/

Or you can define a function in scope:

 $scope.getContent = function(obj){
     return obj.value + " " + obj.text;
 }

And use it this way:

<li ng-repeat=" opt in opts" ng-bind-html-unsafe="getContent(opt)" >
     {{ opt.value }}
</li>

http://jsfiddle.net/gFFBa/4/

Note that you can not do it with an option tag: Can I use HTML tags in the options for select elements?

Simply use JS toLowerCase()
let v = "Your Name" let u = v.toLowerCase(); or
let u = "Your Name".toLowerCase();

It looks like you were on the right track... The ^ character matches beginning-of-line, and $ matches end-of-line. Jonathan's pattern will work for you... just wanted to give you the explanation behind it

When your title doesn't fit on your business card because you wear too many hats, then someone wordsmiths a nifty title for you.

e.g. Programming/IT/Project Management/Strategy/Business Analyst

Other ways to receive an architect title:

• You spend more time on the phone and at the whiteboard than you do actually developing working software.
• You spend more time helping people set up Outlook/Entourage than you do actually developing working software.
• You're really not that good of a coder to begin with.

Simply add these code before setting Adapter it's working for me:

    listView.destroyDrawingCache();
    listView.setVisibility(ListView.INVISIBLE);
    listView.setVisibility(ListView.VISIBLE);

It`s best way for convert the Relative path to the absolute path!

string absolutePath = System.IO.Path.GetFullPath(relativePath);

You should return only one column and one row in the where query where you assign the returned value to a variable. Example:

select * from table1 where Date in (select * from Dates) -- Wrong
select * from table1 where Date in (select Column1,Column2 from Dates) -- Wrong
select * from table1 where Date in (select Column1 from Dates) -- OK

The reason for this error is because there is a mismatch of the ABI between your app and the native library you linked against. Another words, your app and your .so is targeting different ABI.

if you create your app using latest Android Studio templates, its probably targeting the arm64-v8a but your .so may be targeting armeabi-v7a for example.

There is 2 way to solve this problem:

1. build your native libraries for each ABI your app support.
2. change your app to target older ABI that your .so built against.

Choice 2 is dirty but I think you probably have more interested in:

change your app's build.gradle

android {
    defaultConfig {
        ...
        ndk {
            abiFilters 'armeabi-v7a'
        }
   }
}

Only second approach will work. You can modify collection during iteration using iterator.remove() only. All other attempts will cause ConcurrentModificationException.

EDIT

To prevent problems with stale links (I have found MSDN blogs to disappear for no reason in the past), in essence for Windows 7 you need to download and install Remote Server Administration Tools (KB958830). After installing do the following steps:

• Open Control Panel -> Programs and Features -> Turn On/Off Windows Features
• Find "Remote Server Administration Tools" and expand it
• Find "Role Administration Tools" and expand it
• Find "AD DS And AD LDS Tools" and expand it
• Check the box next to "Active Directory Module For Windows PowerShell".
• Click OK and allow Windows to install the feature

Windows server editions should already be OK but if not you need to download and install the Active Directory Management Gateway Service. If any of these links should stop working, you should still be able search for the KB article or download names and find them.

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

If you are using a certificate signed by a Certificate Authority that is not included in the Java cacerts file by default, you need to complete the following configuration for HTTPS connections. To import certificates into cacerts:

1. Open Windows Explorer and navigate to the cacerts file, which is located in the jre\lib\security subfolder where AX Core Client is installed. The default location is C:\Program Files\ACL Software\AX Core Client\jre\lib\security
2. Create a backup copy of the file before making any changes.
3. Depending on the certificates you receive from the Certificate Authority you are using, you may need to import an intermediate certificate and/or root certificate into the cacerts file. Use the following syntax to import certificates: keytool -import -alias -keystore -trustcacerts -file
4. If you are importing both certificates the alias specified for each certificate should be unique.
5. Type the password for the keystore at the “Password” prompt and press Enter. The default Java password for the cacerts file is “changeit”. Type ‘y’ at the “Trust this certificate?” prompt and press Enter.

While I have recently become a convert to dplyr for most of these types of operations, the sqldf package is still really nice (and IMHO more readable) for some things.

Here is an example of how this question can be answered with sqldf

x <- data.frame(Category=factor(c("First", "First", "First", "Second",
                                  "Third", "Third", "Second")), 
                Frequency=c(10,15,5,2,14,20,3))

sqldf("select 
          Category
          ,sum(Frequency) as Frequency 
       from x 
       group by 
          Category")

##   Category Frequency
## 1    First        30
## 2   Second         5
## 3    Third        34

This can be improved by using the directive designed for that task.

ErrorDocument 403 /specific_page.html
Order Allow,Deny
Allow from 111.222.333.444

Where 111.222.333.444 is your static IP address.

When using the "Order Allow,Deny" directive the requests must match either Allow or Deny, if neither is met, the request is denied.

If you use the string literal exactly as you have shown us, the problem is the ; character at the end. You may not include that in the query string in the JDBC calls.

As you are inserting only a single row, a regular INSERT should be just fine even when inserting multiple rows. Using a batched statement is probable more efficient anywy. No need for INSERT ALL. Additionally you don't need the temporary clob and all that. You can simplify your method to something like this (assuming I got the parameters right):

String query1 = "select substr(to_char(max_data),1,4) as year, " + 
  "substr(to_char(max_data),5,6) as month, max_data " +
  "from dss_fin_user.acq_dashboard_src_load_success " + 
  "where source = 'CHQ PeopleSoft FS'";

String query2 = ".....";

String sql = "insert into domo_queries (clob_column) values (?)";
PreparedStatement pstmt = con.prepareStatement(sql);
StringReader reader = new StringReader(query1);
pstmt.setCharacterStream(1, reader, query1.length());
pstmt.addBatch();

reader = new StringReader(query2);
pstmt.setCharacterStream(1, reader, query2.length());
pstmt.addBatch();

pstmt.executeBatch();   
con.commit();

I know this is an old thread but thought I should mention that the extern keyword. I've recently ran into this issue and solved as follows

Helper.h

namespace DX
{
    extern inline void ThrowIfFailed(HRESULT hr);
}

Helper.cpp

namespace DX
{
    inline void ThrowIfFailed(HRESULT hr)
    {
        if (FAILED(hr))
        {
            std::stringstream ss;
            ss << "#" << hr;
            throw std::exception(ss.str().c_str());
        }
    }
}

Allocate maximum memory to your docker machine from (docker preference -> advance )

Screenshot of advance settings:

This will set the maximum limit docker consume while running containers. Now run your image in new container with -m=4g flag for 4 gigs ram or more. e.g.

docker run -m=4g {imageID}

Remember to apply the ram limit increase changes. Restart the docker and double check that ram limit did increased. This can be one of the factor you not see the ram limit increase in docker containers.

First the quick and dirty way, and second the precise way (recognizing daylight's savings or not).

As Rick Vanover mentions in See what process is using a TCP port in Windows Server 2008

The following command will show what network traffic is in use at the port level:

Netstat -a -n -o

or

Netstat -a -n -o >%USERPROFILE%\ports.txt

(to open the port and process list in a text editor, where you can search for information you want)

Then,

with the PIDs listed in the netstat output, you can follow up with the Windows Task Manager (taskmgr.exe) or run a script with a specific PID that is using a port from the previous step. You can then use the "tasklist" command with the specific PID that corresponds to a port in question.

Example:

tasklist /svc /FI "PID eq 1348"

Short answer: 400-800 pixels.

What I have read is that HTML newsletter width should be as narrow as possible without being too narrow. For instance, 400-500 pixels for a one column layout is a lower limit. Any less may look too weird.

Today's widescreen monitors allow for more horizontal pixels and most web email clients will either be of the two-column variety (Gmail) or 3-pane layout where the content window bellow the inbox list (Hotmail and Yahoo). In either case, you can be okay with 800 pixels if you're targeting the 1280 wide audience. An older or less technical audience may have older, square monitors.

There is the problem of Outlook having a three-column layout. That limits the width of your email even more. With them, you may want to go even narrower.

I just recently created a template that required an ad banner that is 730 pixels wide. It was near in the wide range, but not so much that most people could not double-click the email an open a new window in Outlook (the web email users should be okay for the most part).

Hope this advice helps.

Andrey Tarasevich provides the following explanation:

1. On Google Groups
2. On bytes.com

[Minor changes to formatting made. Parenthetical annotations added in square brackets []].

The whole idea of using 'do/while' version is to make a macro which will expand into a regular statement, not into a compound statement. This is done in order to make the use of function-style macros uniform with the use of ordinary functions in all contexts.

Consider the following code sketch:

if (<condition>)
  foo(a);
else
  bar(a);

where foo and bar are ordinary functions. Now imagine that you'd like to replace function foo with a macro of the above nature [named CALL_FUNCS]:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

Now, if your macro is defined in accordance with the second approach (just { and }) the code will no longer compile, because the 'true' branch of if is now represented by a compound statement. And when you put a ; after this compound statement, you finished the whole if statement, thus orphaning the else branch (hence the compilation error).

One way to correct this problem is to remember not to put ; after macro "invocations":

if (<condition>)
  CALL_FUNCS(a)
else
  bar(a);

This will compile and work as expected, but this is not uniform. The more elegant solution is to make sure that macro expand into a regular statement, not into a compound one. One way to achieve that is to define the macro as follows:

#define CALL_FUNCS(x) \
do { \
  func1(x); \
  func2(x); \
  func3(x); \
} while (0)

Now this code:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

will compile without any problems.

However, note the small but important difference between my definition of CALL_FUNCS and the first version in your message. I didn't put a ; after } while (0). Putting a ; at the end of that definition would immediately defeat the entire point of using 'do/while' and make that macro pretty much equivalent to the compound-statement version.

I don't know why the author of the code you quoted in your original message put this ; after while (0). In this form both variants are equivalent. The whole idea behind using 'do/while' version is not to include this final ; into the macro (for the reasons that I explained above).

I know this is an older issue, but I recently had the same problem and was having issues resolving it, despite attempting the DisplayUnlockCaptcha fix. This is how I got it alive.

Head over to Account Security Settings (https://www.google.com/settings/security/lesssecureapps) and enable "Access for less secure apps", this allows you to use the google smtp for clients other than the official ones.

Update

Google has been so kind as to list all the potential problems and fixes for us. Although I recommend trying the less secure apps setting. Be sure you are applying these to the correct account.

• If you've turned on 2-Step Verification for your account, you might need to enter an App password instead of your regular password.
• Sign in to your account from the web version of Gmail at https://mail.google.com. Once you’re signed in, try signing in
  to the mail app again.
• Visit http://www.google.com/accounts/DisplayUnlockCaptcha and sign in with your Gmail username and password. If asked, enter the
  letters in the distorted picture.
• Your app might not support the latest security standards. Try changing a few settings to allow less secure apps access to your account.
• Make sure your mail app isn't set to check for new email too often. If your mail app checks for new messages more than once every 10
  minutes, the app’s access to your account could be blocked.

double[][] is an array of arrays and double[,] is a matrix. If you want to initialize an array of array, you will need to do this:

double[][] ServicePoint = new double[10][]
for(var i=0;i<ServicePoint.Length;i++)
    ServicePoint[i] = new double[9];

Take in account that using arrays of arrays will let you have arrays of different lengths:

ServicePoint[0] = new double[10];
ServicePoint[1] = new double[3];
ServicePoint[2] = new double[5];
//and so on...

From the answer here, spark.sql.shuffle.partitions configures the number of partitions that are used when shuffling data for joins or aggregations.

spark.default.parallelism is the default number of partitions in RDDs returned by transformations like join, reduceByKey, and parallelize when not set explicitly by the user. Note that spark.default.parallelism seems to only be working for raw RDD and is ignored when working with dataframes.

If the task you are performing is not a join or aggregation and you are working with dataframes then setting these will not have any effect. You could, however, set the number of partitions yourself by calling df.repartition(numOfPartitions) (don't forget to assign it to a new val) in your code.

To change the settings in your code you can simply do:

sqlContext.setConf("spark.sql.shuffle.partitions", "300")
sqlContext.setConf("spark.default.parallelism", "300")

Alternatively, you can make the change when submitting the job to a cluster with spark-submit:

./bin/spark-submit --conf spark.sql.shuffle.partitions=300 --conf spark.default.parallelism=300

Check out my code for opening Facebook specific Page:

            String urlPage = "http://www.facebook.com/MDSaziburRahmanBD";

            try {

To expand on juanpa.arrivillaga's comment:

If you want to update Spyder in the root environment, then conda update spyder works for me.

If you want to update Spyder for a virtual environment you have created (e.g., for a different version of Python), then conda update -n $ENV_NAME spyder where $ENV_NAME is your environment name.

EDIT: In case conda update spyder isn't working, this post indicates you might need to run conda update anaconda before updating spyder. Also note that you can specify an exact spyder version if you want.

With your private key and public certificate, you need to create a PKCS12 keystore first, then convert it into a JKS.

# Create PKCS12 keystore from private key and public certificate.
openssl pkcs12 -export -name myservercert -in selfsigned.crt -inkey server.key -out keystore.p12

# Convert PKCS12 keystore into a JKS keystore
keytool -importkeystore -destkeystore mykeystore.jks -srckeystore keystore.p12 -srcstoretype pkcs12 -alias myservercert

To verify the contents of the JKS, you can use this command:

keytool -list -v -keystore mykeystore.jks

If this was not a self-signed certificate, you would probably want to follow this step with importing the certificate chain leading up to the trusted CA cert.

Try ::after on previous element.

For most it is a breeze, however like you I had a difficult time installing jq

The best resources I found are: https://stedolan.github.io/jq/download/ and http://macappstore.org/jq/

However neither worked for me. I run python 2 & 3, and use brew in addition to pip, as well as Jupyter. I was only successful after brew uninstall jq then updating brew and rebooting my system

What worked for me was removing all previous installs then pip install jq

I think you used somehow the right way to show the number only on the keyboard so better try the given line with xml in your edit text and it will work perfectly so here the code is-

In case any doubt you can again ask to me i'll try to completely sort out your problem. Thanks

If you're open to using a third-party library, you can use the Collectors2 class in Eclipse Collections to convert the List to a Bag using a Stream. A Bag is a data structure that is built for counting.

Bag<String> counted =
        list.stream().collect(Collectors2.countBy(each -> each));

Assert.assertEquals(1, counted.occurrencesOf("World"));
Assert.assertEquals(2, counted.occurrencesOf("Hello"));

System.out.println(counted.toStringOfItemToCount());

Output:

{World=1, Hello=2}

In this particular case, you can simply collect the List directly into a Bag.

Bag<String> counted = 
        list.stream().collect(Collectors2.toBag());

You can also create the Bag without using a Stream by adapting the List with the Eclipse Collections protocols.

Bag<String> counted = Lists.adapt(list).countBy(each -> each);

or in this particular case:

Bag<String> counted = Lists.adapt(list).toBag();

You could also just create the Bag directly.

Bag<String> counted = Bags.mutable.with("Hello", "Hello", "World");

A Bag<String> is like a Map<String, Integer> in that it internally keeps track of keys and their counts. But, if you ask a Map for a key it doesn't contain, it will return null. If you ask a Bag for a key it doesn't contain using occurrencesOf, it will return 0.

The following works for me in Gradle / Groovy for build.gradle for an Android project, without having to import groovy.io.FileType (NOTE: Does not recurse subdirectories, but when I found this solution I no longer cared about recursion, so you may not either):

FileCollection proGuardFileCollection = files { file('./proguard').listFiles() }
proGuardFileCollection.each {
    println "Proguard file located and processed: " + it
}

The enum (abbreviation of enumeration) is used to enumerate a set of values (enumerators). A value is an abstract thing represented by a symbol (a word). For example, a basic enum could be

enum { xs,s,m,l,xl,xxl,xxxl,xxxxl };

This enum is called anonymous because you do not have a symbol to name it. But it is still perfectly correct. Just use it like this

enum { xs,s,m,l,xl,xxl,xxxl,xxxxl } myGrandMotherDressSize;

Ok. The life is beautiful and everything goes well. But one day you need to reuse this enum to define a new variable to store myGrandFatherPantSize, then you write:

enum { xs,s,m,l,xl,xxl,xxxl,xxxxl } myGrandMotherDressSize;
enum { xs,s,m,l,xl,xxl,xxxl,xxxxl } myGrandFatherPantSize;

But then you have a compiler error "redefinition of enumerator". Actually, the problem is that the compiler is not sure that you first enum and you are second describe the same thing.

Then if you want to reuse the same set of enumerators (here xs...xxxxl) in several places you must tag it with a unique name. The second time you use this set you just have to use the tag. But don't forget that this tag does not replace the enum word but just the set of enumerators. Then take care to use enum as usual. Like this:

// Here the first use of my enum
enum sizes { xs,s,m,l,xl,xxl,xxxl,xxxxl } myGrandMotherDressSize; 
// here the second use of my enum. It works now!
enum sizes myGrandFatherPantSize;

you can use it in a parameter definition as well:

// Observe that here, I still use the enum
- (void) buyANewDressToMyGrandMother:(enum sizes)theSize;

You could say that rewriting enum everywhere is not convenient and makes the code looks a bit strange. You are right. A real type would be better.

This is the final step of our great progression to the summit. By just adding a typedef let's transform our enum in a real type. Oh the last thing, typedef is not allowed within your class. Then define your type just above. Do it like this:

// enum definition
enum sizes { xs,s,m,l,xl,xxl,xxxl,xxxxl };
typedef enum sizes size_type

@interface myClass {
   ...
   size_type myGrandMotherDressSize, myGrandFatherPantSize;
   ...
}

Remember that the tag is optional. Then since here, in that case, we do not tag the enumerators but just to define a new type. Then we don't really need it anymore.

// enum definition
typedef enum { xs,s,m,l,xl,xxl,xxxl,xxxxl } size_type;

@interface myClass : NSObject {
  ...
  size_type myGrandMotherDressSize, myGrandFatherPantSize;
  ...
}
@end

If you are developing in Objective-C with XCode I let you discover some nice macros prefixed with NS_ENUM. That should help you to define good enums easily and moreover will help the static analyzer to do some interesting checks for you before to compile.

Good Enum!

As with modern browser, placeholder is supported by new version of Chrome / Firefox, similar as the C style function printf().

Placeholders:

• %s String.
• %d,%i Integer number.
• %f Floating point number.
• %o Object hyperlink.

e.g.

console.log("generation 0:\t%f, %f, %f", a1a1, a1a2, a2a2);

BTW, to see the output:

• In Chrome, use shortcut Ctrl + Shift + J or F12 to open developer tool.
• In Firefox, use shortcut Ctrl + Shift + K or F12 to open developer tool.

@Update - nodejs support

Seems nodejs don't support %f, instead, could use %d in nodejs. With %d number will be printed as floating number, not just integer.

None of these answers worked for me. I'm now using:

document.addEventListener('dragleave', function(e){

    var top = e.pageY;
    var right = document.body.clientWidth - e.pageX;
    var bottom = document.body.clientHeight - e.pageY;
    var left = e.pageX;

    if(top < 10 || right < 20 || bottom < 10 || left < 10){
        console.log('Mouse has moved out of window');
    }

});

I'm using this for a drag and drop file uploading widget. It's not absolutely accurate, being triggered when the mouse gets to a certain distance from the edge of the window.

Please install openssl from below link:
https://code.google.com/p/openssl-for-windows/downloads/list
then set the variables below:

OPENSSL_ROOT_DIR=D:/softwares/visualStudio/openssl-0.9.8k_WIN32
OPENSSL_INCLUDE_DIR=D:/softwares/visualStudio/openssl-0.9.8k_WIN32/include
OPENSSL_LIBRARIES=D:/softwares/visualStudio/openssl-0.9.8k_WIN32/lib

=VLOOKUP(Left(A1,1),B$2:B$22,2,FALSE)

Left is because you are starting the word/alphanumeric text from the left. the number "1" which i have placed is after lookup value in this case "A1" is because my search includes the formula for 1st character. If second character is asked it would be (A1,2) quite simple really :)

EDIT :
http://codepen.io/gcyrillus/pen/daCyu So for a popup, you have to use position:fixed , display:table property and max-width with em or rem values :) with this CSS basis :

#popup {
  position:fixed;
  width:100%;
  height:100%;
  display:table;
  pointer-events:none;
}
#popup > div {
  display:table-cell;
  vertical-align:middle;
}
#popup p {
  width:80%;
  max-width:20em;
  margin:auto;
  pointer-events:auto;
}

Here's a complete example of an HTTP GET request with parameters using angular.js in ASP.NET MVC:

CONTROLLER:

public class AngularController : Controller
{
    public JsonResult GetFullName(string name, string surname)
    {
        System.Diagnostics.Debugger.Break();
        return Json(new { fullName = String.Format("{0} {1}",name,surname) }, JsonRequestBehavior.AllowGet);
    }
}

VIEW:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
<script type="text/javascript">
    var myApp = angular.module("app", []);

    myApp.controller('controller', function ($scope, $http) {

        $scope.GetFullName = function (employee) {

            //The url is as follows - ControllerName/ActionName?name=nameValue&surname=surnameValue

            $http.get("/Angular/GetFullName?name=" + $scope.name + "&surname=" + $scope.surname).
            success(function (data, status, headers, config) {
                alert('Your full name is - ' + data.fullName);
            }).
            error(function (data, status, headers, config) {
                alert("An error occurred during the AJAX request");
            });

        }
    });

Use Cygwin...

it has 32 and 64 bits versions
and it works fine from Windows 2000 (*)
to Windows 10 or Server 2019

I use Cygwin for a long time...
and recently tryed to substitute with Windows-Linux-Subsystems...

not for long...
I quickly went back to Cygwin again...

much more flexible, controlable and rich...
also less intrusive...

just add \bin to the path...
and you can use it anyware in Windows/Batch/Powershell...
or in a DOS-Box... or in a Powershell-Box...

Also you can install a ton of great packages
that really work... like nginX or PHP... I even use the Cygwin PHP package in my IIS...

As a bonus wou can also use it from a bash shell...
(I think this was the original intent ;-))

  if cond1 == 'val1' and \
     cond2 == 'val2' and \
     cond3 == 'val3' and \
     cond4 == 'val4':
      do_something

or if this is clearer:

  if cond1 == 'val1'\
     and cond2 == 'val2'\
     and cond3 == 'val3'\
     and cond4 == 'val4':
      do_something

There is no reason indent should be a multiple of 4 in this case, e.g. see "Aligned with opening delimiter":

http://google-styleguide.googlecode.com/svn/trunk/pyguide.html?showone=Indentation#Indentation

string[] filePaths = Directory.GetFiles(@"c:\MyDir\");
foreach (string filePath in filePaths)
File.Delete(filePath);

Or in a single line:

Array.ForEach(Directory.GetFiles(@"c:\MyDir\"), File.Delete);

please make sure following changes should be uncommented, which I did and got succeed in centos7

vi /etc/ssh/sshd_config

1.PubkeyAuthentication yes

2.PasswordAuthentication yes

3.GSSAPIKeyExchange no

4.GSSAPICleanupCredentials no

systemctl restart sshd

ssh-keygen

chmod 777 /root/.ssh/id_rsa.pub 

ssh-copy-id -i /root/.ssh/id_rsa.pub user@ipaddress

thank you all and good luck

You can also create a HTML alert template like this:

<div class="alert alert-info" id="alert_template" style="display: none;">
    <button type="button" class="close">×</button>
</div>

And so you can do in JavaScript this here:

$("#alert_template button").after('<span>Some text</span>');
$('#alert_template').fadeIn('slow');

Which is in my opinion cleaner and faster. In addition you stick to Twitter Bootstrap standards when calling fadeIn().

To guarantee that this alert template works also with multiple calls (so it doesn't add the new message to the old one), add this here to your JavaScript:

$('#alert_template .close').click(function(e) {
    $("#alert_template span").remove();
});

So this call removes the span element every time you close the alert via the x-button.

Download php5.dll (http://windows.php.net/download/) and copy it to apache/bin folder. That solved it for me (Win 7 64 bit apache 32 bit)

EDIT: Start with the non-thread safe version.

Ref this

SELECT * FROM product WHERE name REGEXP '[0-9]'

A function name can become a variable name (and thus be passed as an argument) by dropping the parentheses. A variable name can become a function name by adding the parentheses.

In your example, equate the variable rules to one of your functions, leaving off the parentheses and the mention of the argument. Then in your game() function, invoke rules( v ) with the parentheses and the v parameter.

if puzzle == type1:
    rules = Rule1
else:
    rules = Rule2

def Game(listA, listB, rules):
    if rules( v ) == True:
        do...
    else:
        do...

To get it to work with Apache, we needed one extra step.

openssl pkcs12 -in domain.pfx -clcerts -nokeys -out domain.cer
openssl pkcs12 -in domain.pfx -nocerts -nodes  -out domain_encrypted.key
openssl rsa -in domain_encrypted.key -out domain.key

The final command decrypts the key for use with Apache. The domain.key file should look like this:

-----BEGIN RSA PRIVATE KEY-----
MjQxODIwNTFaMIG0MRQwEgYDVQQKEwtFbnRydXN0Lm5ldDFAMD4GA1UECxQ3d3d3
LmVudHJ1c3QubmV0L0NQU18yMDQ4IGluY29ycC4gYnkgcmVmLiAobGltaXRzIGxp

MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEArU1LqRKGsuqjIAcVFmQq
-----END RSA PRIVATE KEY-----

For Windows or Linux users, a possible solution is described on GitHub Docs, which I report below for your convenience.

You can run ssh-agent automatically when you open bash or Git shell. Copy the following lines and paste them into your ~/.profile or ~/.bashrc file:

env=~/.ssh/agent.env

agent_load_env () { test -f "$env" && . "$env" >| /dev/null ; }

agent_start () {
    (umask 077; ssh-agent >| "$env")
    . "$env" >| /dev/null ; }

agent_load_env

# agent_run_state: 0=agent running w/ key; 1=agent w/o key; 2= agent not running
agent_run_state=$(ssh-add -l >| /dev/null 2>&1; echo $?)

if [ ! "$SSH_AUTH_SOCK" ] || [ $agent_run_state = 2 ]; then
    agent_start
    ssh-add
elif [ "$SSH_AUTH_SOCK" ] && [ $agent_run_state = 1 ]; then
    ssh-add
fi

unset env

If your private key is not stored in one of the default locations (like ~/.ssh/id_rsa), you'll need to tell your SSH authentication agent where to find it. To add your key to ssh-agent, type ssh-add ~/path/to/my_key.

Now, when you first run Git Bash, you are prompted for your passphrase. The ssh-agent process will continue to run until you log out, shut down your computer, or kill the process.

From the Intel's manual - Instruction Set Reference, the JE and JZ have the same opcode (74 for rel8 / 0F 84 for rel 16/32) also JNE and JNZ (75 for rel8 / 0F 85 for rel 16/32) share opcodes.

JE and JZ they both check for the ZF (or zero flag), although the manual differs slightly in the descriptions of the first JE rel8 and JZ rel8 ZF usage, but basically they are the same.

Here is an extract from the manual's pages 464, 465 and 467.

 Op Code    | mnemonic  | Description
 -----------|-----------|-----------------------------------------------  
 74 cb      | JE rel8   | Jump short if equal (ZF=1).
 74 cb      | JZ rel8   | Jump short if zero (ZF ? 1).

 0F 84 cw   | JE rel16  | Jump near if equal (ZF=1). Not supported in 64-bit mode.
 0F 84 cw   | JZ rel16  | Jump near if 0 (ZF=1). Not supported in 64-bit mode.

 0F 84 cd   | JE rel32  | Jump near if equal (ZF=1).
 0F 84 cd   | JZ rel32  | Jump near if 0 (ZF=1).

 75 cb      | JNE rel8  | Jump short if not equal (ZF=0).
 75 cb      | JNZ rel8  | Jump short if not zero (ZF=0).

 0F 85 cd   | JNE rel32 | Jump near if not equal (ZF=0).
 0F 85 cd   | JNZ rel32 | Jump near if not zero (ZF=0).

How about using this pure CSS line? I find this the cleanest solution for a dialog with given Id:

.ui-dialog[aria-describedby="IdValueOfDialog"] .ui-dialog-titlebar-close { display: none; }

Easily done in Bootstrap 3 like so:

import java.awt.event.ActionListener;
import java.awt.image.BufferedImage;

    b.setBounds(380, 290, 120, 60);
    b.setBackground(Color.red);
    b.setVisible(true);
    b.addActionListener(this);
    add(b);
    setSize(1000, 700);
}
public void actionPerformed(ActionEvent e)

    if (e.getSource() == b)

            Toolkit tk = Toolkit.getDefaultToolkit(); 
            Dimension d = tk.getScreenSize();
            Rectangle rec = new Rectangle(0, 0, d.width, d.height);  
            Robot ro = new Robot();
            BufferedImage img = ro.createScreenCapture(rec);
            File f = new File("myimage.jpg");//set appropriate path
            ImageIO.write(img, "jpg", f);
        } catch (Exception ex) {
            System.out.println(ex.getMessage());
        }
    }
}

public static void main(String[] args) {

}
}

Recursive solution to print all items in a list:

def printItems(l):
   for i in l:
      if isinstance(i,list):
         printItems(i)
      else:
         print i


l = [['vegas','London'],['US','UK']]
printItems(l)

I think the extension is intended to allow a similar syntax for inserts and updates. In Oracle, a similar syntactical trick is:

UPDATE table SET (col1, col2) = (SELECT val1, val2 FROM dual)

Try / \([\s\S]*?\)/g

Where

(space) matches the character (space) literally

\( matches the character ( literally

[\s\S] matches any character (\s matches any whitespace character and \S matches any non-whitespace character)

*? matches between zero and unlimited times

\) matches the character ) literally

g matches globally

Code Example:

var str = "Hello, this is Mike (example)";
str = str.replace(/ \([\s\S]*?\)/g, '');
console.log(str);

.as-console-wrapper {top: 0}

here is the sample code to draw image on canvas-

$("#selectedImage").change(function(e) {

var URL = window.URL;
var url = URL.createObjectURL(e.target.files[0]);
img.src = url;

img.onload = function() {
    var canvas = document.getElementById("myCanvas");
    var ctx = canvas.getContext("2d");        

    ctx.clearRect(0, 0, canvas.width, canvas.height);
    ctx.drawImage(img, 0, 0, 500, 500);
}});

In the above code selectedImage is an input control which can be used to browse image on system. For more details of sample code to draw image on canvas while maintaining the aspect ratio:

http://newapputil.blogspot.in/2016/09/show-image-on-canvas-html5.html

I too had the same problem. Digging into this I found that the Exception class has an args attribute, which captures the arguments that were used to create the exception. If you narrow the exceptions that except will catch to a subset, you should be able to determine how they were constructed, and thus which argument contains the message.

try:
   # do something that may raise an AuthException
except AuthException as ex:
   if ex.args[0] == "Authentication Timeout.":
      # handle timeout
   else:
      # generic handling

If this is for an intranet application and all of the clients use DHCP, you can query the DHCP server for the MAC address for a given IP address.

Mario, I don't understand why you used recursion for that example.. Why not simply loop through each entry? Something like this:

String ArrangeString(TStringList* items, String separator)
{
    String result = items->Strings[0];

    for (int position=1; position < items->count; position++) {
        result += separator + items->Strings[position];
    }

    return result;
}

The above method would be faster, and is simpler. There's no need to use recursion in place of a simple loop. I think these sorts of examples is why recursion gets a bad rap. Even the canonical factorial function example is better implemented with a loop.

Here is how I did it by trial and error.

ScrollView - (the outer wrapper).

    LinearLayout (child-1).

        LinearLayout (child-1a).

        LinearLayout (child-1b).

Since ScrollView can have only one child, that child is a linear layout. Then all the other layout types occur in the first linear layout. I haven't tried to include a relative layout yet, but they drive me nuts so I will wait until my sanity returns.

Here's what I've been doing to cope with the situation.

I use global imports on a new test class.

import static org.junit.Assert.*;
import static org.mockito.Mockito.*;
import static org.mockito.Matchers.*;

When you are finished writing your test and need to commit, you just CTRL+SHIFT+O to organize the packages. For example, you may just be left with:

import static org.mockito.Mockito.doThrow;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.verify;
import static org.mockito.Mockito.when;
import static org.mockito.Matchers.anyString;

This allows you to code away without getting 'stuck' trying to find the correct package to import.

Some details (PL)

As we can read here (Peter Gulutzan) there is difference on sorting/comparing polish letter "L" (L with stroke - html esc: Ł) (lower case: "l" - html esc: ł) - we have following assumption:

utf8_polish_ci      L greater than L and less than M
utf8_unicode_ci     L greater than L and less than M
utf8_unicode_520_ci L equal to L
utf8_general_ci     L greater than Z

In polish language letter L is after letter L and before M. No one of this coding is better or worse - it depends of your needs.
