I just wrote array intersection that correctly handles also duplicates

https://gist.github.com/gkucmierz/8ee04544fa842411f7553ef66ac2fcf0

// array intersection that correctly handles also duplicates_x000D_
_x000D_
const intersection = (a1, a2) => {_x000D_
  const cnt = new Map();_x000D_
  a2.map(el => cnt[el] = el in cnt ? cnt[el] + 1 : 1);_x000D_
  return a1.filter(el => el in cnt && 0 < cnt[el]--);_x000D_
};_x000D_
_x000D_
const l = console.log;_x000D_
l(intersection('1234'.split``, '3456'.split``)); // [ '3', '4' ]_x000D_
l(intersection('12344'.split``, '3456'.split``)); // [ '3', '4' ]_x000D_
l(intersection('1234'.split``, '33456'.split``)); // [ '3', '4' ]_x000D_
l(intersection('12334'.split``, '33456'.split``)); // [ '3', '3', '4' ]

You could read the entire input line from scanner, then split the line by , then you have a String[], parse each number into int[] with index one to one matching...(assuming valid input and no NumberFormatExceptions) like

String line = scanner.nextLine();
String[] numberStrs = line.split(",");
int[] numbers = new int[numberStrs.length];
for(int i = 0;i < numberStrs.length;i++)
{
   // Note that this is assuming valid input
   // If you want to check then add a try/catch 
   // and another index for the numbers if to continue adding the others (see below)
   numbers[i] = Integer.parseInt(numberStrs[i]);
}

As YoYo's answer suggests, the above can be achieved more concisely in Java 8:

int[] numbers = Arrays.stream(line.split(",")).mapToInt(Integer::parseInt).toArray();  

To handle invalid input

You will need to consider what you want need to do in this case, do you want to know that there was bad input at that element or just skip it.

If you don't need to know about invalid input but just want to continue parsing the array you could do the following:

int index = 0;
for(int i = 0;i < numberStrs.length;i++)
{
    try
    {
        numbers[index] = Integer.parseInt(numberStrs[i]);
        index++;
    }
    catch (NumberFormatException nfe)
    {
        //Do nothing or you could print error if you want
    }
}
// Now there will be a number of 'invalid' elements 
// at the end which will need to be trimmed
numbers = Arrays.copyOf(numbers, index);

The reason we should trim the resulting array is that the invalid elements at the end of the int[] will be represented by a 0, these need to be removed in order to differentiate between a valid input value of 0.

Results in

Input: "2,5,6,bad,10"
Output: [2,3,6,10]

If you need to know about invalid input later you could do the following:

Integer[] numbers = new Integer[numberStrs.length];
for(int i = 0;i < numberStrs.length;i++)        
{
    try 
    {
        numbers[i] = Integer.parseInt(numberStrs[i]);
    }
    catch (NumberFormatException nfe)   
    {
        numbers[i] = null;
    }
}

In this case bad input (not a valid integer) the element will be null.

Results in

Input: "2,5,6,bad,10"
Output: [2,3,6,null,10]

You could potentially improve performance by not catching the exception (see this question for more on this) and use a different method to check for valid integers.

In case you're trying to access an item from the example structure by id or name, without knowing it's position in the array, the easiest way to do it would be to use underscore.js library:

var data = {
    code: 42,
    items: [{
        id: 1,
        name: 'foo'
    }, {
        id: 2,
        name: 'bar'
    }]
};

_.find(data.items, function(item) {
  return item.id === 2;
});
// Object {id: 2, name: "bar"}

From my experience, using higher order functions instead of for or for..in loops results in code that is easier to reason about, and hence more maintainable.

Just my 2 cents.

Arrgh, I can't get the code to show up correctly. Sorry, I got it working. Sorry again, I don't think I read the question properly.

String  foo[] = {"a","cc","a","dd"},
remove = "a";
boolean gaps[] = new boolean[foo.length];
int newlength = 0;

for (int c = 0; c<foo.length; c++)
{
    if (foo[c].equals(remove))
    {
        gaps[c] = true;
        newlength++;
    }
    else 
        gaps[c] = false;

    System.out.println(foo[c]);
}

String newString[] = new String[newlength];

System.out.println("");

for (int c1=0, c2=0; c1<foo.length; c1++)
{
    if (!gaps[c1])
    {
        newString[c2] = foo[c1];
        System.out.println(newString[c2]);
        c2++;
    }
}

Modified version of divround :-)

def divround(value, step, barrage):
    result, rest = divmod(value, step)
    return result*step if rest < barrage else (result+1)*step

In my scripts, I either use the shorthand:

window.console && console.log(...) // only log if the function exists

or, if it's not possible or feasible to edit every console.log line, I create a fake console:

// check to see if console exists. If not, create an empty object for it,
// then create and empty logging function which does nothing. 
//
// REMEMBER: put this before any other console.log calls
!window.console && (window.console = {} && window.console.log = function () {});

Have a look at the below code snippet.

@RequestMapping(value="/Add/{type}")
public ModelAndView addForm(@PathVariable String type ){
    ModelAndView modelAndView = new ModelAndView();
    modelAndView.setViewName("addContent");
    modelAndView.addObject("typelist",contentPropertyDAO.getType() );
    modelAndView.addObject("property",contentPropertyDAO.get(type,0) );
    return modelAndView;
}

Hope it helps in constructing your code.

For another approach, note that all the standard library functions work with floating point types. You can implement an integer type function like this:

unsigned power(unsigned base, unsigned degree)
{
    unsigned result = 1;
    unsigned term = base;
    while (degree)
    {
        if (degree & 1)
            result *= term;
        term *= term;
        degree = degree >> 1;
    }
    return result;
}

This effectively does repeated multiples, but cuts down on that a bit by using the bit representation. For low integer powers this is quite effective.

I have a angular 5 + spring boot app(application.properties 1.3+) with help of compression(link attached below) was able to reduce the size of main.bundle.ts size from 2.7 MB to 530 KB.

Also by default --aot and --build-optimizer are enabled with --prod mode you need not specify those separately.

If you are using Java 1.7, you can use java.nio.file.Files.walkFileTree(...).

For example:

public class WalkFileTreeExample {

  public static void main(String[] args) {
    Path p = Paths.get("/usr");
    FileVisitor<Path> fv = new SimpleFileVisitor<Path>() {
      @Override
      public FileVisitResult visitFile(Path file, BasicFileAttributes attrs)
          throws IOException {
        System.out.println(file);
        return FileVisitResult.CONTINUE;
      }
    };

    try {
      Files.walkFileTree(p, fv);
    } catch (IOException e) {
      e.printStackTrace();
    }
  }

}

If you are using Java 8, you can use the stream interface with java.nio.file.Files.walk(...):

public class WalkFileTreeExample {

  public static void main(String[] args) {
    try (Stream<Path> paths = Files.walk(Paths.get("/usr"))) {
      paths.forEach(System.out::println);
    } catch (IOException e) {
      e.printStackTrace();
    }
  }

}

It really depends on the type of HTML file you're creating.

For such tasks, I use to create an object, serialize it to XML, then transform it with XSL. The pros of this approach are:

• The strict separation between source code and HTML template,
• The possibility to edit HTML without having to recompile the application,
• The ability to serve different HTML in different cases based on the same XML, or even serve XML directly when needed (for a further deserialization for example),
• The shorter amount of code to write.

The cons are:

• You must know XSLT and know how to implement it in Java.
• You must write XSLT (and it's torture for many developers).
• When transforming XML to HTML with XSLT, some parts may be tricky. Few examples: <textarea/> tags (which make the page unusable), XML declaration (which can cause problems with IE), whitespace (with <pre></pre> tags etc.), HTML entities ( ), etc.
• The performance will be reduced, since serialization to XML wastes lots of CPU resources and XSL transformation is very costly too.

Now, if your HTML is very short or very repetitive or if the HTML has a volatile structure which changes dynamically, this approach must not be taken in account. On the other hand, if you serve HTML files which have all a similar structure and you want to reduce the amount of Java code and use templates, this approach may work.

If I understand this correctly, here's how I would phrase this from the perspective of the function implementing IEnumerable with yield.

• Here's one.
• Call again if you need another.
• I'll remember what I already gave you.
• I'll only know if I can give you another when you call again.

Here is an efficient way to solve this question using For loops in Java

 public static void main(String[] args) {

    int [] numbers = { 1, 2, 3, 4 };
    int size = numbers.length;

    int sum = 0;
    for (int i = 0; i < size; i++) {
        sum += numbers[i];
    }

    System.out.println(sum);
}

You can also use

   $(document).ready(function() {

    //some even that will run ajax request - for example click on a button

    var uname = $('#username').val();
    $.ajax({
    type: 'POST',
    url: 'func.php', //this should be url to your PHP file
    dataType: 'html',
    data: {func: 'toptable', user_id: uname},
    beforeSend: function() {
        $('#right').html('checking');
    },
    complete: function() {},
    success: function(html) {
        $('#right').html(html);
    }
    });

    });
And your func.php:

  function toptable()
 {
  echo 'something happens in here';
 }

Hope it helps somebody

If there are only two references to test and you are using Java 8, you could use

Object o = null;
Object p = "p";
Object r = Optional.ofNullable( o ).orElse( p );
System.out.println( r );   // p

If you import static Optional the expression is not too bad.

Unfortunately your case with "several variables" is not possible with an Optional-method. Instead you could use:

Object o = null;
Object p = null;
Object q = "p";

Optional<Object> r = Stream.of( o, p, q ).filter( Objects::nonNull ).findFirst();
System.out.println( r.orElse(null) );   // p

Here is my JSFiddle with corrected line breaks, or see it below.

$(document).ready(function() {

var MaxInputs       = 2; //maximum extra input boxes allowed
var InputsWrapper   = $("#InputsWrapper"); //Input boxes wrapper ID
var AddButton       = $("#AddMoreFileBox"); //Add button ID

var x = InputsWrapper.length; //initlal text box count
var FieldCount=1; //to keep track of text box added

//on add input button click
$(AddButton).click(function (e) {
        //max input box allowed
        if(x <= MaxInputs) {
            FieldCount++; //text box added ncrement
            //add input box
            $(InputsWrapper).append('<div><input type="text" name="mytext[]" id="field_'+ FieldCount +'"/> <a href="#" class="removeclass">Remove</a></div>');
            x++; //text box increment

            $("#AddMoreFileId").show();

            $('AddMoreFileBox').html("Add field");

            // Delete the "add"-link if there is 3 fields.
            if(x == 3) {
                $("#AddMoreFileId").hide();
                $("#lineBreak").html("<br>");
            }
        }
        return false;
});

$("body").on("click",".removeclass", function(e){ //user click on remove text
        if( x > 1 ) {
                $(this).parent('div').remove(); //remove text box
                x--; //decrement textbox

                $("#AddMoreFileId").show();

                $("#lineBreak").html("");

                // Adds the "add" link again when a field is removed.
                $('AddMoreFileBox').html("Add field");
        }
    return false;
}) 

});

Use the WebView. Simple!!

http://developer.android.com/reference/android/webkit/WebView.html

I had to find a quick solution, so I just used a TextBox with those properties:

var myLabel = new TextBox
                    {
                        Text = "xxx xxx xxx",
                        WordWrap = true,
                        AutoSize = false,
                        Enabled = false,
                        Size = new Size(60, 30),
                        BorderStyle = BorderStyle.None,
                        Multiline =  true,
                        BackColor =  container.BackColor
                    };

If your system has systemctl

sudo systemctl reload nginx

If your system supports service (using debian/ubuntu) try this

sudo service nginx reload

If not (using centos/fedora/etc) you can try the init script

sudo /etc/init.d/nginx reload

Your condition is wrong. myChar != 'n' || myChar != 'N' will always be true.

Use myChar != 'n' && myChar != 'N' instead

A little late to the party, but I took @Hristiyan Dodov's answer a bit further still.

First you need to start karma server with

karma start

Then, you can use grep to filter a specific test or describe block:

karma run -- --grep=testDescriptionFilter

In python 2.7, the / operator is integer division if inputs are integers.

If you want float division (which is something I always prefer), just use this special import:

from __future__ import division

See it here:

>>> 7 / 2
3
>>> from __future__ import division
>>> 7 / 2
3.5
>>>

Integer division is achieved by using //, and modulo by using %

>>> 7 % 2
1
>>> 7 // 2
3
>>>

EDIT

As commented by user2357112, this import has to be done before any other normal import.

for me, I have to add

xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"

right after:

xmlns:android="http://schemas.android.com/apk/res/android"

in res/layout/main.xml

return false;

return false; does 3 separate things when you call it:

1. event.preventDefault() – It stops the browsers default behaviour.
2. event.stopPropagation() – It prevents the event from propagating (or “bubbling up”) the DOM.
3. Stops callback execution and returns immediately when called.

Note that this behaviour differs from normal (non-jQuery) event handlers, in which, notably, return false does not stop the event from bubbling up.

preventDefault();

preventDefault(); does one thing: It stops the browsers default behaviour.

When to use them?

We know what they do but when to use them? Simply it depends on what you want to accomplish. Use preventDefault(); if you want to “just” prevent the default browser behaviour. Use return false; when you want to prevent the default browser behaviour and prevent the event from propagating the DOM. In most situations where you would use return false; what you really want is preventDefault().

Examples:

Let’s try to understand with examples:

We will see pure JAVASCRIPT example

Example 1:

<div onclick='executeParent()'>_x000D_
  <a href='https://stackoverflow.com' onclick='executeChild()'>Click here to visit stackoverflow.com</a>_x000D_
</div>_x000D_
<script>_x000D_
  function executeChild() {_x000D_
    alert('Link Clicked');_x000D_
  }_x000D_
_x000D_
  function executeParent() {_x000D_
    alert('div Clicked');_x000D_
  }_x000D_
</script>

Run the above code you will see the hyperlink ‘Click here to visit stackoverflow.com‘ now if you click on that link first you will get the javascript alert Link Clicked Next you will get the javascript alert div Clicked and immediately you will be redirected to stackoverflow.com.

Example 2:

<div onclick='executeParent()'>_x000D_
  <a href='https://stackoverflow.com' onclick='executeChild()'>Click here to visit stackoverflow.com</a>_x000D_
</div>_x000D_
<script>_x000D_
  function executeChild() {_x000D_
    event.preventDefault();_x000D_
    event.currentTarget.innerHTML = 'Click event prevented'_x000D_
    alert('Link Clicked');_x000D_
  }_x000D_
_x000D_
  function executeParent() {_x000D_
    alert('div Clicked');_x000D_
  }_x000D_
</script>

Run the above code you will see the hyperlink ‘Click here to visit stackoverflow.com‘ now if you click on that link first you will get the javascript alert Link Clicked Next you will get the javascript alert div Clicked Next you will see the hyperlink ‘Click here to visit stackoverflow.com‘ replaced by the text ‘Click event prevented‘ and you will not be redirected to stackoverflow.com. This is due > to event.preventDefault() method we used to prevent the default click action to be triggered.

Example 3:

<div onclick='executeParent()'>_x000D_
  <a href='https://stackoverflow.com' onclick='executeChild()'>Click here to visit stackoverflow.com</a>_x000D_
</div>_x000D_
<script>_x000D_
  function executeChild() {_x000D_
    event.stopPropagation();_x000D_
    event.currentTarget.innerHTML = 'Click event prevented'_x000D_
    alert('Link Clicked');_x000D_
  }_x000D_
_x000D_
  function executeParent() {_x000D_
    alert('div Clicked');_x000D_
  }_x000D_
</script>

This time if you click on Link the function executeParent() will not be called and you will not get the javascript alert div Clicked this time. This is due to us having prevented the propagation to the parent div using event.stopPropagation() method. Next you will see the hyperlink ‘Click here to visit stackoverflow.com‘ replaced by the text ‘Click event is going to be executed‘ and immediately you will be redirected to stackoverflow.com. This is because we haven’t prevented the default click action from triggering this time using event.preventDefault() method.

Example 4:

<div onclick='executeParent()'>_x000D_
  <a href='https://stackoverflow.com' onclick='executeChild()'>Click here to visit stackoverflow.com</a>_x000D_
</div>_x000D_
<script>_x000D_
  function executeChild() {_x000D_
    event.preventDefault();_x000D_
    event.stopPropagation();_x000D_
    event.currentTarget.innerHTML = 'Click event prevented'_x000D_
    alert('Link Clicked');_x000D_
  }_x000D_
_x000D_
  function executeParent() {_x000D_
    alert('Div Clicked');_x000D_
  }_x000D_
</script>

If you click on the Link, the function executeParent() will not be called and you will not get the javascript alert. This is due to us having prevented the propagation to the parent div using event.stopPropagation() method. Next you will see the hyperlink ‘Click here to visit stackoverflow.com‘ replaced by the text ‘Click event prevented‘ and you will not be redirected to stackoverflow.com. This is because we have prevented the default click action from triggering this time using event.preventDefault() method.

Example 5:

For return false I have three examples and all appear to be doing the exact same thing (just returning false), but in reality the results are quite different. Here's what actually happens in each of the above.

cases:

1. Returning false from an inline event handler prevents the browser from navigating to the link address, but it doesn't stop the event from propagating through the DOM.
2. Returning false from a jQuery event handler prevents the browser from navigating to the link address and it stops the event from propagating through the DOM.
3. Returning false from a regular DOM event handler does absolutely nothing.

Will see all three example.

1. Inline return false.

<div onclick='executeParent()'>_x000D_
  <a href='https://stackoverflow.com' onclick='return false'>Click here to visit stackoverflow.com</a>_x000D_
</div>_x000D_
<script>_x000D_
  var link = document.querySelector('a');_x000D_
_x000D_
  link.addEventListener('click', function() {_x000D_

You should read that, it's still valid.

You'll adapt the function you use depending on your needs.

Basically:

• if you already load all entries, say User.all, then you should use length to avoid another db query

• if you haven't anything loaded, use count to make a count query on your db

• if you don't want to bother with these considerations, use size which will adapt

basically i use this in one of our apps: we want to overlay a playicon over a frame of a video:

Image playbutton;
try
{
    playbutton = Image.FromFile(/*somekindofpath*/);
}
catch (Exception ex)
{
    return;
}

Image frame;
try
{
    frame = Image.FromFile(/*somekindofpath*/);
}
catch (Exception ex)
{
    return;
}

using (frame)
{
    using (var bitmap = new Bitmap(width, height))
    {
        using (var canvas = Graphics.FromImage(bitmap))
        {
            canvas.InterpolationMode = InterpolationMode.HighQualityBicubic;
            canvas.DrawImage(frame,
                             new Rectangle(0,
                                           0,
                                           width,
                                           height),
                             new Rectangle(0,
                                           0,
                                           frame.Width,
                                           frame.Height),
                             GraphicsUnit.Pixel);
            canvas.DrawImage(playbutton,
                             (bitmap.Width / 2) - (playbutton.Width / 2),
                             (bitmap.Height / 2) - (playbutton.Height / 2));
            canvas.Save();
        }
        try
        {
            bitmap.Save(/*somekindofpath*/,
                        System.Drawing.Imaging.ImageFormat.Jpeg);
        }
        catch (Exception ex) { }
    }
}

You're thinking too complicated. It's actually just $('#'+openaddress).

boolean whitespaceSearchRegExp(String input) {

    return java.util.regex.Pattern.compile("\\s").matcher(input).find();

}

Example:

.parent-class .flex-control-thumbs li {
  width: auto;
  float: none;
}

Demo:

.sample-class {
  height: 50px;
  width: 50px;
  background: red;
}

.inner-page .sample-class {
  background: green;
}

Reference docs of docker: https://docs.docker.com/install/linux/linux-postinstall/#configure-where-the-docker-daemon-listens-for-connections

There are 2 ways in configuring the docker daemon port

1) Configuring at /etc/default/docker file:

DOCKER_OPTS="-H tcp://127.0.0.1:5000 -H unix:///var/run/docker.sock"

2) Configuring at /etc/docker/daemon.json:

{
"debug": true,
"hosts": ["tcp://127.0.0.1:5000", "unix:///var/run/docker.sock"]
}

If the docker default socket is not configured Docker will wait for infinite period.i.e

Waiting for /var/run/docker.sock
Waiting for /var/run/docker.sock
Waiting for /var/run/docker.sock
Waiting for /var/run/docker.sock
Waiting for /var/run/docker.sock

NOTE : BUT DON'T CONFIGURE IN BOTH THE CONFIGURATION FILES, the following error may occur :

Waiting for /var/run/docker.sock
unable to configure the Docker daemon with file /etc/docker/daemon.json: the following directives are specified both as a flag and in the configuration file: hosts: (from flag: [tcp://127.0.0.1:5000 unix:///var/run/docker.sock], from file: tcp://127.0.0.1:5000)

The reason for adding both the user port[ tcp://127.0.0.1:5000] and default docker socket[unix:///var/run/docker.sock] is that the user port enables the access to the docker APIs whereas the default socket enables the CLI. In case the default port[unix:///var/run/docker.sock] is not mentioned in /etc/default/docker file the following error may occur:

# docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

This error is not because that the docker is not running, but because of default docker socket is not enabled.

Once the configuration is enabled restart the docker service and verify the docker port is enabled or not:

# netstat -tunlp | grep -i 5000
tcp        0      0 127.0.0.1:5000          0.0.0.0:*               LISTEN      31661/dockerd 

Applicable for Docker Version 17.04, may vary with different versions of docker.

I had the same problem. I wanted to 'bury' a folder at the bottom of the sort instead of bringing it to the top with the '!' character. Windows recognizes most special characters as just that, 'special', and therefore they ALL are sorted at the top.

However, if you think outside of the English characters, you will find a lot of luck. I used Character Map and the arial font, scrolled down past '~' and the others to the greek alphabet. Capitol Xi, ?, worked best for me, but I didn't check to see which was the actual 'lowest' in the sort.

Make variables are not exported into the environment of processes make invokes... by default. However you can use make's export to force them to do so. Change:

test: NODE_ENV = test

to this:

test: export NODE_ENV = test

(assuming you have a sufficiently modern version of GNU make >= 3.77 ).

While this doesn't avoid the problem of parentheses, for the sake of people getting here via Google, it should be mentioned that newer syntax exists (as of C# 7) to make the rest of your code a little cleaner:

if (!(DocumentPart is IContainer container)) { return; }
foreach(DocumentPart child in container.Children) {
    ...

This avoids the double-cast, the null-check, and having a variable available in scopes where it could be null.

IF there is not only jQuery or other resource killing frameworks - many kb to download each time by each user just for a simple trick - but also native JavaScript(!):

<img src="img1_on.jpg" 
    onclick="this.src=this.src.match(/_on/)?'img1_off.jpg':'img1_on.jpg';">
<img src="img2_on.jpg" 
    onclick="this.src=this.src.match(/_on/)?'img2_off.jpg':'img2_on.jpg';">

This can be written general and more elegant:

<html>
<head>
<script>
function switchImg(img){
    img.src = img.src.match(/_on/) ? 
        img.src.replace(/_on/, "_off") : 
        img.src.replace(/_off/, "_on");
}
</script>
</head>
<body>
    <img src="img1_on.jpg" onclick="switchImg(this)">
    <img src="img2_on.jpg" onclick="switchImg(this)">
</body>
</html>

Just put yourRelativeLayout inside ScrollView

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ScrollView01"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
  ------- here RelativeLayout ------

In a situation where you are using just spring and not spring mvc, take the following approach.

Place the following in servlet dispatcher

<mvc:annotation-driven />               
<mvc:resources mapping="/css/**" location="/WEB-INF/assets/css/"/>
<mvc:resources mapping="/js/**" location="/WEB-INF/assets/js/"/>

As you will notice /css for stylesheet location, doesn't have to be in /resources folder if you don't have the folder structure required for spring mvc as is the case with a spring application.Same applies to javascript files, fonts if you need them etc.

You can then access the resources as you need them like so

<link rel="stylesheet" href="css/vendor/swiper.min.css" type="text/css" />
<link rel="stylesheet" href="css/styles.css" type="text/css" />

I am sure someone will find this useful as most examples are with spring mvc

addDateMonate : function( pDatum, pAnzahlMonate )

    }

    var vv = new Date();

    var jahr = pDatum.getFullYear();
    var monat = pDatum.getMonth() + 1;
    var tag = pDatum.getDate();

    var add_monate_total = Math.abs( Number( pAnzahlMonate ) );

    var add_jahre = Number( Math.floor( add_monate_total / 12.0 ) );
    var add_monate_rest = Number( add_monate_total - ( add_jahre * 12.0 ) );

    if ( Number( pAnzahlMonate ) > 0 )
    {

        monat += add_monate_rest;

I managed to find a solution using css/jQuery that I'm comfortable with. The original issue: I had to force the visibility to be shown while animating as I have elements hanging outside the area. Doing so, made large blocks of text now hang outside the content area during animation as well.

The solution was to start the main text elements with an opacity of 0 and use addClass to inject and transition to an opacity of 1. Then removeClass when clicked on again.

I'm sure there's an all jQquery way to do this. I'm just not the guy to do it. :)

So in it's most basic form...

.slideDown().addClass("load");
.slideUp().removeClass("load");

Thanks for the help everyone.

For user configuration I've noticed a tendency towards moving away from individual ~/.myprogramrc to a structure below ~/.config. For example, Qt 4 uses ~/.config/<vendor>/<programname> with the default settings of QSettings. The major desktop environments KDE and Gnome use a file structure below a specific folder too (not sure if KDE 4 uses ~/.config, XFCE does use ~/.config).

I do recomend doing it in 2 filles (.h .cpp) But if u lazy just add inline before the function So it will look something like this

inline void functionX() 
{ }

more about inline functions:

The inline functions are a C++ enhancement feature to increase the execution time of a program. Functions can be instructed to compiler to make them inline so that compiler can replace those function definition wherever those are being called. Compiler replaces the definition of inline functions at compile time instead of referring function definition at runtime. NOTE- This is just a suggestion to compiler to make the function inline, if function is big (in term of executable instruction etc) then, compiler can ignore the “inline” request and treat the function as normal function.

more info here

The simple way to do your test is :

function (data) {
    if (data) { // check if null, undefined, empty ...
        // some code here
    }
}

You do not have to install something.

parseInt(req.params.year, 10);

should work properly.

console.log(typeof parseInt(req.params.year)); // returns 'number'

What is your output, if you use parseInt? is it still a string?

As stated in problem, to solve this error you MUST use correct annotations. In above problem, @NotBlank or @NotEmpty annotation must be applied on any String field only.

To validate long type field, use annotation @NotNull.

I've had this same dependency problem and I also know that you can include the VS 8.0 DLLs (release only! not debug!---and your program has to be release, too) in a folder of the appropriate name, in the parent folder with your .exe:

How to: Deploy using XCopy (MSDN)

Also note that things are guaranteed to go awry if you need to have C++ and C code in the same statically linked .exe because you will get linker conflicts that can only be resolved by ignoring the correct libXXX.lib and then linking dynamically (DLLs).

Lastly, with a different toolset (VC++ 6.0) things "just work", since Windows 2000 and above have the correct DLLs installed.

I find adding this to django models quite helpful:

def __iter__(self):
    for field_name in self._meta.get_all_field_names():
        value = getattr(self, field_name, None)
        yield (field_name, value)

This lets you do:

for field, val in object:
    print field, val

print "bla: ", $_, "\n" if ($_ = $myvar) =~ s/a/b/g or 1;

With this version of python 3:

/opt/anaconda3/bin/python --version
Python 3.6.0 :: Anaconda 4.3.0 (64-bit)

Looking at the details of the error, I found the lines of codes causing the failure:

/opt/anaconda3/lib/python3.6/site-packages/sklearn/utils/validation.py in _assert_all_finite(X)
     56             and not np.isfinite(X).all()):
     57         raise ValueError("Input contains NaN, infinity"
---> 58                          " or a value too large for %r." % X.dtype)
     59 
     60 

ValueError: Input contains NaN, infinity or a value too large for dtype('float64').

From this, I was able to extract the correct way to test what was going on with my data using the same test which fails given by the error message: np.isfinite(X)

Then with a quick and dirty loop, I was able to find that my data indeed contains nans:

print(p[:,0].shape)
index = 0
for i in p[:,0]:
    if not np.isfinite(i):
        print(index, i)
    index +=1

(367340,)
4454 nan
6940 nan
10868 nan
12753 nan
14855 nan
15678 nan
24954 nan
30251 nan
31108 nan
51455 nan
59055 nan
...

Now all I have to do is remove the values at these indexes.

What you could do is add the text as value, which respects the line break \n.

$('textarea').attr('value', 'This is a line \nthis should be a new line');

Then you could remove it on focus and apply it back (if empty) on blur. Something like this

var placeholder = 'This is a line \nthis should be a new line';
$('textarea').attr('value', placeholder);

$('textarea').focus(function(){
    if($(this).val() === placeholder){
        $(this).attr('value', '');
    }
});

$('textarea').blur(function(){
    if($(this).val() ===''){
        $(this).attr('value', placeholder);
    }    
});

Not pure CSS and not clean but does the trick.

We use Liquid XML Studio, it provides a intuitive editable representation of an XSD schema. It also shows the annotations inline, which we find very useful and the split code/gfx view is invaluable when writting or editing an XSD.

In short:

1. static_cast<>() gives you a compile time checking ability, C-Style cast doesn't.
2. static_cast<>() is more readable and can be spotted easily anywhere inside a C++ source code, C_Style cast is'nt.
3. Intentions are conveyed much better using C++ casts.

More Explanation:

The static cast performs conversions between compatible types. It is similar to the C-style cast, but is more restrictive. For example, the C-style cast would allow an integer pointer to point to a char.

char c = 10;       // 1 byte
int *p = (int*)&c; // 4 bytes

Since this results in a 4-byte pointer ( a pointer to 4-byte datatype) pointing to 1 byte of allocated memory, writing to this pointer will either cause a run-time error or will overwrite some adjacent memory.

*p = 5; // run-time error: stack corruption

In contrast to the C-style cast, the static cast will allow the compiler to check that the pointer and pointee data types are compatible, which allows the programmer to catch this incorrect pointer assignment during compilation.

int *q = static_cast<int*>(&c); // compile-time error

After this:

INSERT INTO aspnet_GameProfiles(UserId, GameId) OUTPUT INSERTED.ID VALUES(@UserId, @GameId)

Execute this

int id = (int)command.ExecuteScalar;

It will work

You can get the development version from here.

Modern browsers do not currently implement JSONRequest (as far as I know) since it is only a draft right now. I have found someone who has implemented it as a library that you can include in your page: http://devpro.it/JSON/files/JSONRequest-js.html (please note that it has a few dependencies).

Otherwise, you might want to go with another JS library like jQuery or Mootools.

You can quickly review the changes made to a file using the diff command:

git diff <commit hash> <filename>

Then to revert a specific file to that commit use the reset command:

git reset <commit hash> <filename>

You may need to use the --hard option if you have local modifications.

A good workflow for managaging waypoints is to use tags to cleanly mark points in your timeline. I can't quite understand your last sentence but what you may want is diverge a branch from a previous point in time. To do this, use the handy checkout command:

git checkout <commit hash>
git checkout -b <new branch name>

You can then rebase that against your mainline when you are ready to merge those changes:

git checkout <my branch>
git rebase master
git checkout master
git merge <my branch>

try this

 public void VolleyPostReqWithResponseListenerwithHeaders(String URL,final Map<String, String> params,final Map<String, String> headers,Response.Listener<String> responseListener) {


    String url = URL;

    Log.i("url:", ":" + url);
    StringRequest mStringRequest = new StringRequest(Request.Method.POST,
            url, responseListener, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            // error


            //Log.d("Error.Response", error.getLocalizedMessage());
        }
    }){
        @Override
        protected Map<String, String> getParams() {
            return params;
        }

        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            return headers;
        }
    };



    mStringRequest.setRetryPolicy(new DefaultRetryPolicy(
            60000,
            DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
            DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

    mStringRequest.setShouldCache(true);



    //  dialog.show();
    SingletonRequestQueue.getInstance(context).addToRequestQueue(mStringRequest);
}

Simple way to count is,

$currentdate = date('Y-m-d H:i:s');
$after1yrdate =  date("Y-m-d H:i:s", strtotime("+1 year", strtotime($data)));

$diff = (strtotime($after1yrdate) - strtotime($currentdate)) / (60 * 60 * 24);

echo "<p style='color:red'>The difference is ".round($diff)." Days</p>";

To start with, I do not suggest using "*" in regexes. Yes, I know, it is the most used multi-character delimiter, but it is nevertheless a bad idea. This is because, while it does match any amount of repetition for that character, "any" includes 0, which is usually something you want to throw a syntax error for, not accept. Instead, I suggest using the + sign, which matches any repetition of length > 1. What's more, from what I can see, you are dealing with fixed-length parenthesized expressions. As a result, you can probably use the {x, y} syntax to specifically specify the desired length.

However, if you really do need non-greedy repetition, I suggest consulting the all-powerful ?. This, when placed after at the end of any regex repetition specifier, will force that part of the regex to find the least amount of text possible.

That being said, I would be very careful with the ? as it, like the Sonic Screwdriver in Dr. Who, has a tendency to do, how should I put it, "slightly" undesired things if not carefully calibrated. For example, to use your example input, it would identify ((1) (note the lack of a second rparen) as a match.

As you can see, there are several ways to achieve this.

I personally use:

Expand all: CTRL + M + L

Collapse all: CTRL + M + O

Bonus:

Expand/Collapse on cursor location: CTRL + M + M

first thing first, all shards failed exception is not as dramatic as it sounds, it means shards were failed while serving a request(query or index), and there could be multiple reasons for it like

1. Shards are actually in non-recoverable state, if your cluster and index state are in Yellow and RED, then it is one of the reason.
2. Due to some shard recovery happening in background, shards didn't respond.
3. Due to bad syntax of your query, ES responds in all shards failed.

In order to fix the issue, you need to filter it in one of the above category and based on that appropriate fix is required.

The one mentioned in the question, is clearly in the first bucket as cluster health is RED, means one or more primary shards are missing, and my this SO answer will help you fix RED cluster issue, which will fix the all shards exception in this case.

For WPF:

YourButtonName.RaiseEvent(new RoutedEventArgs(System.Windows.Controls.Primitives.ButtonBase.ClickEvent));

WHERE dates BETWEEN (convert(datetime, '2012-12-12',110) AND (convert(datetime, '2012-12-12',110))

The appropriate LC would be

[entry for tag in tags for entry in entries if tag in entry]

The order of the loops in the LC is similar to the ones in nested loops, the if statements go to the end and the conditional expressions go in the beginning, something like

[a if a else b for a in sequence]

See the Demo -

>>> tags = [u'man', u'you', u'are', u'awesome']
>>> entries = [[u'man', u'thats'],[ u'right',u'awesome']]
>>> [entry for tag in tags for entry in entries if tag in entry]
[[u'man', u'thats'], [u'right', u'awesome']]
>>> result = []
    for tag in tags:
        for entry in entries:
            if tag in entry:
                result.append(entry)


>>> result
[[u'man', u'thats'], [u'right', u'awesome']]

EDIT - Since, you need the result to be flattened, you could use a similar list comprehension and then flatten the results.

>>> result = [entry for tag in tags for entry in entries if tag in entry]
>>> from itertools import chain
>>> list(chain.from_iterable(result))
[u'man', u'thats', u'right', u'awesome']

Adding this together, you could just do

>>> list(chain.from_iterable(entry for tag in tags for entry in entries if tag in entry))
[u'man', u'thats', u'right', u'awesome']

You use a generator expression here instead of a list comprehension. (Perfectly matches the 79 character limit too (without the list call))

While Niemeyer's answer is a more correct answer to the question, you could also do the following:

<div>
  <input data-bind="value: VMA.name" />
</div>

<div>
  <input data-bind="value: VMB.name" />
</div>

<script type="text/javascript">
  var viewModels = {
     VMA: {name: ko.observable("Bob")},
     VMB: {name: ko.observable("Ted")}
  };

  ko.applyBindings(viewModels);
</script>

This means you don't have to specify the DOM element, and you can even bind multiple models to the same element, like this:

<div>
  <input data-bind="value: VMA.name() + ' and ' + VMB.name()" />
</div>

Since you are not interested in keeping any data, drop the entire database and create a new one.

You can set environment variables in the notebook using os.environ. Do the following before initializing TensorFlow to limit TensorFlow to first GPU.

import os
os.environ["CUDA_DEVICE_ORDER"]="PCI_BUS_ID"   # see issue #152
os.environ["CUDA_VISIBLE_DEVICES"]="0"

You can double check that you have the correct devices visible to TF

from tensorflow.python.client import device_lib
print device_lib.list_local_devices()

I tend to use it from utility module like notebook_util

import notebook_util
notebook_util.pick_gpu_lowest_memory()
import tensorflow as tf

I once had an issue like this, when i downloadad a lib from Amazon (for Amazon webservices) and that jar file contained a log4j.properties and somehow that was used instead of my good old, self configed log4j. Worth a check.

you should use []

var x = ConfigurationManager.AppSettings["APIKey"];

When debugging optimized programs (which may be necessary if the bug doesn't show up in debug builds), you often have to understand assembly compiler generated.

In your particular case, return value of cpnd_find_exact_ckptinfo will be stored in the register which is used on your platform for return values. On ix86, that would be %eax. On x86_64: %rax, etc. You may need to google for '[your processor] procedure calling convention' if it's none of the above.

You can examine that register in GDB and you can set it. E.g. on ix86:

(gdb) p $eax
(gdb) set $eax = 0 

location.href = location.href;

If you want convert from Json to a typed ArrayList , it's wrong to specify the type of the object contained in the list. The correct syntax is as follows:

 Gson gson = new Gson(); 
 List<MyClass> myList = gson.fromJson(inputString, ArrayList.class);

Please see the below way of deletion too.

Declare @table table
(col1 varchar(10),col2 int,col3 int, col4 int, col5 int, col6 int, col7 int)
Insert into @table values 
('john',1,1,1,1,1,1),
('john',1,1,1,1,1,1),
('sally',2,2,2,2,2,2),
('sally',2,2,2,2,2,2)

Created a sample table named @table and loaded it with given data.

Delete  aliasName from (
Select  *,
        ROW_NUMBER() over (Partition by col1,col2,col3,col4,col5,col6,col7 order by col1) as rowNumber
From    @table) aliasName 
Where   rowNumber > 1

Select * from @table

Note: If you are giving all columns in the Partition by part, then order by do not have much significance.

I know, the question is asked three years ago, and my answer is another version of what Tim has posted, But posting just incase it is helpful for anyone.

If Perl is an option:

perl -F, -lane 'print join ",",@F[0,1,2,3,4,5,6,7,8,9,19,20,21,22,23,24,29,32]'

-a autosplits line into @F fields array. Indices start at 0 (not 1 as in awk)
-F, field separator is ,

If your CSV file contains commas within quotes, fully fledged CSV parsers such as Perl's Text::CSV_XS are purpose-built to handle that kind of weirdness.

perl -MText::CSV_XS -lne 'BEGIN{$csv=Text::CSV_XS->new()} if($csv->parse($_)){@f=$csv->fields();print (join ",",@f[0,1,2,3,4,5,6,7,8,9,19,20,21,22,23,24,29,32])}'

I provided more explanation within my answer here: parse csv file using gawk

This was not what I was expecting as a solution (though it is a legitimate use case). My requirement was to allow an existing buggy client (a mobile app which already released) to use alternate names.

The solution lies in providing a separate setter method like this:

@JsonSetter( "r" )
public void alternateSetRed( byte red ) {
    this.red = red;
}

The ul.nav li is more restrictive and so takes precedence, try this:

ul.nav li.selected {  
  background-color:red; 
}

You would need to enclose the pattern in a delimiter - typically a slash (/) is used. Try this:

echo preg_replace("/[^0-9]/","",'604-619-5135');

$sidemenu is not an object, so you can't call methods on it. It is probably not being sent to your view, or $sidemenus is empty.

I hope this would provide you with the right solution:

Syntax:

   CASE  
        WHEN search_condition THEN statement_list  
       [WHEN search_condition THEN statement_list]....
       [ELSE statement_list]  
   END CASE

Implementation:

select id, action_heading,  
   case when
             action_type="Expense" then action_amount  
             else NULL   
             end as Expense_amt,   
    case when  
             action_type ="Income" then action_amount  
             else NULL  
             end as Income_amt  
  from tbl_transaction;

Here I am using CASE statement as it is more flexible than if-then-else. It allows more than one branch. And CASE statement is standard SQL and works in most databases.

...this is obviously performing a 'string' comparison

No - if the date/time format matches the supported format, MySQL performs implicit conversion to convert the value to a DATETIME, based on the column it is being compared to. Same thing happens with:

WHERE int_column = '1'

...where the string value of "1" is converted to an INTeger because int_column's data type is INT, not CHAR/VARCHAR/TEXT.

If you want to explicitly convert the string to a DATETIME, the STR_TO_DATE function would be the best choice:

WHERE expires_at <= STR_TO_DATE('2010-10-15 10:00:00', '%Y-%m-%d %H:%i:%s')

Use FOR XML PATH('') - which is converting the entries to a comma separated string and STUFF() -which is to trim the first comma- as follows Which gives you the same comma separated result

SELECT  STUFF((SELECT  ',' + INSTITUTIONNAME
            FROM EDUCATION EE
            WHERE  EE.STUDENTNUMBER=E.STUDENTNUMBER
            ORDER BY sortOrder
        FOR XML PATH('')), 1, 1, '') AS listStr

FROM EDUCATION E
GROUP BY E.STUDENTNUMBER

Here is the FIDDLE

Use split()

let mut split = "some string 123 ffd".split("123");

This gives an iterator, which you can loop over, or collect() into a vector.

for s in split {
    println!("{}", s)
}
let vec = split.collect::<Vec<&str>>();
// OR
let vec: Vec<&str> = split.collect();

Yes it's true but you shouldn't care. Go with the one that's easier to read. If you have to benchmark your app, then focus on the bottlenecks.

I would guess that string concatenation isn't going to be your bottleneck.

The Python ValueError:

ValueError: setting an array element with a sequence.

Means exactly what it says, you're trying to cram a sequence of numbers into a single number slot. It can be thrown under various circumstances.

1. When you pass a python tuple or list to be interpreted as a numpy array element:

import numpy

numpy.array([1,2,3])               #good

numpy.array([1, (2,3)])            #Fail, can't convert a tuple into a numpy 
                                   #array element


numpy.mean([5,(6+7)])              #good

numpy.mean([5,tuple(range(2))])    #Fail, can't convert a tuple into a numpy 
                                   #array element


def foo():
    return 3
numpy.array([2, foo()])            #good


def foo():
    return [3,4]
numpy.array([2, foo()])            #Fail, can't convert a list into a numpy 
                                   #array element

2. By trying to cram a numpy array length > 1 into a numpy array element:

x = np.array([1,2,3])
x[0] = np.array([4])         #good



x = np.array([1,2,3])
x[0] = np.array([4,5])       #Fail, can't convert the numpy array to fit 
                             #into a numpy array element

A numpy array is being created, and numpy doesn't know how to cram multivalued tuples or arrays into single element slots. It expects whatever you give it to evaluate to a single number, if it doesn't, Numpy responds that it doesn't know how to set an array element with a sequence.

A compact, flexible method for timestamps without fractional seconds would be:

SELECT * FROM table_name 
WHERE field_name 
BETWEEN UNIX_TIMESTAMP('2010-10-01') AND UNIX_TIMESTAMP('2010-10-31 23:59:59')

If you are using fractional seconds and a recent version of MySQL then you would be better to take the approach of using the >= and < operators as per Wouter's answer.

Here is an example of temporal fields defined with fractional second precision (maximum precision in use):

mysql> create table time_info (t_time time(6), t_datetime datetime(6), t_timestamp timestamp(6), t_short timestamp null);
Query OK, 0 rows affected (0.02 sec)

mysql> insert into time_info set t_time = curtime(6), t_datetime = now(6), t_short = t_datetime;
Query OK, 1 row affected (0.01 sec)

mysql> select * from time_info;

I was playing around with the following code for another question on StackOverflow and thought that it might be appropriate for here.

int is nothing but an interruption i.e the processor will put its current execution to hold.

0x80 is nothing but a system call or the kernel call. i.e the system function will be executed.

To be specific 0x80 represents rt_sigtimedwait/init_module/restart_sys it varies from architecture to architecture.

Service is a base class of service implementation. Service runs on the application's main thread which may reduce the application performance. Thus, IntentService, which is a direct subclass of Service is available to make things easier.

The IntentService is used to perform a certain task in the background. Once done, the instance of IntentService terminates itself automatically. Examples for its usage would be to download a certain resource from the Internet.

Differences

1. Service class uses the application's main thread, while IntentService creates a worker thread and uses that thread to run the service.
2. IntentService creates a queue that passes one intent at a time to onHandleIntent(). Thus, implementing a multi-thread should be made by extending Service class directly. Service class needs a manual stop using stopSelf(). Meanwhile, IntentService automatically stops itself when it finishes execution.
3. IntentService implements onBind() that returns null. This means that the IntentService can not be bound by default.
4. IntentService implements onStartCommand() that sends Intent to queue and to onHandleIntent().

In brief, there are only two things to do to use IntentService. Firstly, to implement the constructor. And secondly, to implement onHandleIntent(). For other callback methods, the super is needed to be called so that it can be tracked properly.

The other answers did not work for me, so I checked Telerik's official documentation it says you need to find the button and call the click() function:

function KeyPressed(sender, eventArgs) {
            var button = $find("<%= RadButton1.ClientID %>");
            button.click();
        }

template<typename T>
string str(T begin, T end)
{
    stringstream ss;
    bool first = true;
    for (; begin != end; begin++)
    {
        if (!first)
            ss << ", ";
        ss << *begin;
        first = false;
    }
    return ss.str();
}

This is the str function that can make integers turn into a string and not into a char for what the integer represents. Also works for doubles.

You can use this extension method for enumerables containing more complex types:

IEnumerable<Foo> distinctList = sourceList.DistinctBy(x => x.FooName);

public static IEnumerable<TSource> DistinctBy<TSource, TKey>(
    this IEnumerable<TSource> source,
    Func<TSource, TKey> keySelector)
{
    var knownKeys = new HashSet<TKey>();
    return source.Where(element => knownKeys.Add(keySelector(element)));
}

List<T>.Remove() and List<T>.RemoveAt() do not return the item that is being removed.

Therefore you have to use this:

var item = list[oldIndex];
list.RemoveAt(oldIndex);
list.Insert(newIndex, item);

Here is a solution I made using the above ideas that can be used for TextBoxFor and PasswordFor:

public static class HtmlHelperEx
{
    public static MvcHtmlString TextBoxWithPlaceholderFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper,
        Expression<Func<TModel, TProperty>> expression, object htmlAttributes)
    {
        var metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
        return htmlHelper.TextBoxFor(expression, htmlAttributes.AddAttribute("placeholder", metadata.Watermark));

    }

    public static MvcHtmlString PasswordWithPlaceholderFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper,
        Expression<Func<TModel, TProperty>> expression, object htmlAttributes)
    {
        var metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
        return htmlHelper.PasswordFor(expression, htmlAttributes.AddAttribute("placeholder", metadata.Watermark));

    }
}

public static class HtmlAttributesHelper
{
    public static IDictionary<string, object> AddAttribute(this object htmlAttributes, string name, object value)
    {
        var dictionary = htmlAttributes == null ? new Dictionary<string, object>() : htmlAttributes.ToDictionary();
        if (!String.IsNullOrWhiteSpace(name) && value != null && !String.IsNullOrWhiteSpace(value.ToString()))
            dictionary.Add(name, value);
        return dictionary;
    }

    public static IDictionary<string, object> ToDictionary(this object obj)
    {
        return TypeDescriptor.GetProperties(obj)
            .Cast<PropertyDescriptor>()
            .ToDictionary(property => property.Name, property => property.GetValue(obj));
    }
}

Use the split function.

static void Main(string[] args)

    string s = "223232-1.jpg";
    Console.WriteLine(s.Split('-')[0]);
    s = "443-2.jpg";

If your string doesn't have a - then you'll get the whole string.

No, because it contains items there must be an instance of it. Its items being null is irrelevant, so the statment ((arrayList) != null) == true

Putting together several answers from above, this is what I ended up using:

var validationErrors = ModelState.Values.Where(E => E.Errors.Count > 0)
    .SelectMany(E => E.Errors)
    .Select(E => E.ErrorMessage)
    .ToList();

validationErrors ends up being a List<string> that contains each error message. From there, it's easy to do what you want with that list.

Ok, you should be using a servlet not a JSP but if you really need to... add this directive at the top of your page:

<%@ page trimDirectiveWhitespaces="true" %>

Or in the jsp-config section your web.xml

<jsp-config>
  <jsp-property-group>
    <url-pattern>*.jsp</url-pattern>
    <trim-directive-whitespaces>true</trim-directive-whitespaces>
  </jsp-property-group>
</jsp-config>

Also flush/close the OutputStream and return when done.

dataOutput.flush();
dataOutput.close();
return;

I have studied a number of Go projects and there is a fair bit of variation. You can kind of tell who is coming from C and who is coming from Java, as the former dump just about everything in the projects root directory in a main package, and the latter tend to put everything in a src directory. Neither is optimal however. Each have consequences because they affect import paths and how others can reuse them.

To get the best results I have worked out the following approach.

myproj/
  main/
    mypack.go
  mypack.go

Where mypack.go is package mypack and main/mypack.go is (obviously) package main.

If you need additional support files you have two choices. Either keep them all in the root directory, or put private support files in a lib subdirectory. E.g.

myproj/
  main/
    mypack.go
  myextras/
    someextra.go
  mypack.go
  mysupport.go

Or

myproj.org/
  lib/
    mysupport.go
    myextras/
      someextra.go
  main/
    mypack.go
  mypage.go

Only put the files in a lib directory if they are not intended to be imported by another project. In other words, if they are private support files. That's the idea behind having lib --to separate public from private interfaces.

Doing things this way will give you a nice import path, myproj.org/mypack to reuse the code in other projects. If you use lib then internal support files will have an import path that is indicative of that, myproj.org/lib/mysupport.

When building the project, use main/mypack, e.g. go build main/mypack. If you have more than one executable you can also separate those under main without having to create separate projects. e.g. main/myfoo/myfoo.go and main/mybar/mybar.go.

For SQL server 2012 or above use EOMONTH to get the last date of month

SQL query to display end date of current month

DECLARE @currentDate DATE = GETDATE()
SELECT EOMONTH (@currentDate) AS CurrentMonthED

SQL query to display end date of Next month

DECLARE @currentDate DATE = GETDATE()
SELECT EOMONTH (@currentDate, 1 ) AS NextMonthED

You can use a ComboBox with its ComboBoxStyle (appears as DropDownStyle in later versions) set to DropDownList. See: http://msdn.microsoft.com/en-us/library/system.windows.forms.comboboxstyle.aspx

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

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

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

Edit:

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

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

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

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

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

For excluding one or more library globally add the following to your build.gradle

configurations.all {
   exclude group:"org.apache.geronimo.specs", module: "geronimo-servlet_2.5_spec"
   exclude group:"ch.qos.logback", module:"logback-core"
}

Now the exclude block has two properties group and module. For those of you coming from maven background, group is same as groupId and module is same as artifactId. Example: To exclude com.mchange:c3p0:0.9.2.1 following should be exclude block

exclude group:"com.mchange", module:"c3p0"

I would do it in this way to make it look more like bash:

Just create a file named .pythonstartup at Home directory and use poke's answer in a function

On Linux:

echo "from subprocess import call
def clear(int=None):  
    call('clear')
    if int == 0:
       exit()
clear()" >> $HOME/.pythonstartup ; export PYTHONSTARTUP=$HOME/.pythonstartup ; python

You can add export PYTHONSTARTUP=$HOME/.pythonstartup to your ./bashrc file

Since what I care about is space; a call to the function will not display the python interpreter description at startup, but you can remove clear() to retain it.

Using it like a normal function should do the trick without printing the exit status:

>>> clear()

If you pass the argument 0 to the function it will clear the screen and exit successfully so you can continue using the shell in a clean screen

>>> clear(0)

If you don't want to modify the registry or app.config files, an alternate way is to create a simple .NET 4 console app that mimicks what PowerShell.exe does and hosts the PowerShell ConsoleShell.

See Option 2 – Hosting Windows PowerShell yourself

First, add a reference to the System.Management.Automation and Microsoft.PowerShell.ConsoleHost assemblies which can be found under %programfiles%\Reference Assemblies\Microsoft\WindowsPowerShell\v1.0

Then use the following code:

using System;
using System.Management.Automation.Runspaces;
using Microsoft.PowerShell;

namespace PSHostCLRv4
{
    class Program
    {
        static int Main(string[] args)
        {
            var config = RunspaceConfiguration.Create();
                return ConsoleShell.Start(
                config,
                "Windows PowerShell - Hosted on CLR v4\nCopyright (C) 2010 Microsoft Corporation. All rights reserved.",
                "",
                args
            );
        }
    }
}

OpenCV HSV range is: H: 0 to 179 S: 0 to 255 V: 0 to 255

On Gimp (or other photo manipulation sw) Hue range from 0 to 360, since opencv put color info in a single byte, the maximum number value in a single byte is 255 therefore openCV Hue values are equivalent to Hue values from gimp divided by 2.

I found when trying to do object detection based on HSV color space that a range of 5 (opencv range) was sufficient to filter out a specific color. I would advise you to use an HSV color palate to figure out the range that works best for your application.

First, look here: http://en.wikipedia.org/wiki/List_of_unit_testing_frameworks#C

From what I've found online, this is a bug introduced in JDK 1.7.0_45. It appears to also be present in JDK 1.7.0_60. A bug report on Oracle's website states that, while there was a fix, it was removed before the JDK was released. I do not know why the fix was removed, but it confirms what we've already suspected -- the JDK is still broken.

The bug report claims that the error is benign and should not cause any run-time problems, though one of the comments disagrees with that. In my own experience, I have been able to work without any problems using JDK 1.7.0_60 despite seeing the message.

If this issue is causing serious problems, here are a few things I would suggest:

• Revert back to JDK 1.7.0_25 until a fix is added to the JDK.

• Keep an eye on the bug report so that you are aware of any work being done on this issue. Maybe even add your own comment so Oracle is aware of the severity of the issue.

• Try the JDK early releases as they come out. One of them might fix your problem.

Instructions for installing the JDK on Mac OS X are available at JDK 7 Installation for Mac OS X. It also contains instructions for removing the JDK.

For posterity sake,the answer maybe too late.You should check for the return value of the variable and throw an exception. In that case you are assured that the program will jump from where the exception is being raised to the catch block. Find below.

try{
   $tableAresults = $dbHandler->doSomethingWithTableA();
   if (!tableAresults) 
     throw new Exception('Problem with tableAresults');

  $tableBresults = $dbHandler->doSomethingElseWithTableB();
   if (!tableBresults) 
     throw new Exception('Problem with tableBresults');
} catch (Exception $e) {
    echo $e->getMessage();

}

Layout file was main_activity.xml so the generate class was MainActivityBinding

Since your xml is named "activity_contact_list.xml", you should use ActivityContactListBinding instead of the original one

The method described in the accepted answer didn't work for me even after applying changes mentioned in its comments. But the below simple code worked:

import matplotlib.pyplot as plt
plt.imsave(filename, np_array, cmap='Greys')

np_array could be either a 2D array with values from 0..1 floats o2 0..255 uint8, and in that case it needs cmap. For 3D arrays, cmap will be ignored.

Just use <br>. Do not use <br></br>. <br> is a special tag which doesn't need a closing unlike most tags.

The problem is in your JSP, most likely you are calling a method on an object that is null at runtime.

It is happening in the _jspInit() call, which is a little more unusual... the problem code is probably a method declaration like <%! %>

Update: I've only reproduced this by overriding the _jspInit() method. Is that what you're doing? If so, it's not recommended - that's why it starts with an _.

One reason why you might prefer to use a JOIN rather than NOT IN is that if the Values in the NOT IN clause contain any NULLs you will always get back no results. If you do use NOT IN remember to always consider whether the sub query might bring back a NULL value!

RE: Question in Comments

'x' NOT IN (NULL,'a','b')

= 'x' <> NULL and 'x' <> 'a' and 'x' <> 'b'

= Unknown and True and True

= Unknown

There is only so much you can do with rm() and gc(). As suggested by Gavin Simpson, even if you free the actual memory in R, Windows often won't reclaim it until you close R or it is needed because all the apparent Windows memory fills up.

This usually isn't a problem. However, if you are running large loops this can sometimes lead to fragmented memory in the long term, such that even if you free the memory and restart R - the fragmented memory may prevent you allocating large chunks of memory. Especially if other applications were allocated fragmented memory while you were running R. rm() and gc() may delay the inevitable, but more RAM is better.

Swift 3 and Swift 4:

I wonder how those rgb coefficients were determined. I did an experiment myself and I ended up with the following:

Y = 0.267 R + 0.642 G + 0.091 B

Close but but obviously different than the long established ITU coefficients. I wonder if those coefficients could be different for each and every observer, because we all may have a different amount of cones and rods on the retina in our eyes, and especially the ratio between the different types of cones may differ.

For reference:

ITU BT.709:

Y = 0.2126 R + 0.7152 G + 0.0722 B

ITU BT.601:

Y = 0.299 R + 0.587 G + 0.114 B

I did the test by quickly moving a small gray bar on a bright red, bright green and bright blue background, and adjusting the gray until it blended in just as much as possible. I also repeated that test with other shades. I repeated the test on different displays, even one with a fixed gamma factor of 3.0, but it all looks the same to me. More over, the ITU coefficients literally are wrong for my eyes.

And yes, I presumably have a normal color vision.

On StackOverflow, pressing the up-vote button is AJAX whereas typing in your question or answer and seeing it appear in the real-time preview window below it is JavaScript (JQuery).

This means that the difference between AJAX and Javascript is that AJAX allows you to communicate with the server without doing a page refresh (i.e. going to a new page) whereas JavaScript (JQuery) allows you to embed logic and behaviour on your page. Of course, with this logic you create AJAX as well.

I think it may be worth mentioning that [ConditionalAttribute] is in the System.Diagnostics; namespace. I stumbled a bit when I got:

Error 2 The type or namespace name 'ConditionalAttribute' could not be found (are you missing a using directive or an assembly reference?)

For those who don't want to use HTML agility pack and want to get HtmlDocument from string using native .net code only here is a good article on how to convert string to HtmlDocument

Here is the code block to use

public System.Windows.Forms.HtmlDocument GetHtmlDocument(string html)
        {
            WebBrowser browser = new WebBrowser();
            browser.ScriptErrorsSuppressed = true;
            browser.DocumentText = html;
            browser.Document.OpenNew(true);
            browser.Document.Write(html);
            browser.Refresh();
            return browser.Document;
        }

For those who still don't get the accepted solution :

Add

import React from 'react'
import ReactDOM from 'react-dom'

at the top of the file.

None of the above worked for me.

This happened to me after I added a new button to a toolstrip on a winform. When the button uses the default image of System.Drawing.Bitmap (in image property) this error arose for me. After I changed it to a trusted image (one added to my resource file with 'Unlock' option checked) this error resolved itself.

Like Eliran Malka asked, why do you need to check for IE 9?

Detecting browser make and version is generally a bad smell. This generally means that you there is a bigger problem with the code if you need JavaScript to detect specific versions of browser.

There are genuine cases where a feature won't work, like say WebSockets isn't supported in IE 8 or 9. This should be solved by checking for WebSocket support, and applying a polyfill if there is no native support.

This should be done with a library like Modernizr.

That being said, you can easily create service that would return the browser. There are valid cases where a feature exists in a browser but the implementation is outdated or broken. Modernizr is not appropriate for these cases.

app.service('browser', ['$window', function($window) {

     return function() {

         var userAgent = $window.navigator.userAgent;

        var browsers = {chrome: /chrome/i, safari: /safari/i, firefox: /firefox/i, ie: /internet explorer/i};

        for(var key in browsers) {
            if (browsers[key].test(userAgent)) {
                return key;
            }
       };

       return 'unknown';
    }

}]);

Fixed typo broswers

Note: This is just an example of how to create a service in angular that will sniff the userAgent string. This is just a code example that is not expected to work in production and report all browsers in all situations.

UPDATE

It is probably best to use a third party library like https://github.com/ded/bowser or https://github.com/darcyclarke/Detect.js. These libs place an object on the window named bowser or detect respectively.

You can then expose this to the Angular IoC Container like this:

angular.module('yourModule').value('bowser', bowser);

Or

detectFactory.$inject = ['$window'];
function detectFactory($window) {
    return detect.parse($window.navigator.userAgent);
} 
angular.module('yourModule').factory('detect', detectFactory);

You would then inject one of these the usual way, and use the API provided by the lib. If you choose to use another lib that instead uses a constructor method, you would create a factory that instantiates it:

function someLibFactory() {
    return new SomeLib();
}
angular.module('yourModule').factory('someLib', someLibFactory);

You would then inject this into your controllers and services the normal way.

If the library you are injecting does not exactly match your requirements, you may want to employ the Adapter Pattern where you create a class/constructor with the exact methods you need.

In this example we just need to test for IE 9, and we are going to use the bowser lib above.

BrowserAdapter.$inject = ['bowser']; // bring in lib
function BrowserAdapter(bowser) {
    this.bowser = bowser;
}

BrowserAdapter.prototype.isIe9 = function() {
    return this.bowser.msie && this.browser.version == 9;
}

angular.module('yourModule').service('browserAdapter', BrowserAdapter);

Now in a controller or service you can inject the browserAdapter and just do if (browserAdapter.isIe9) { // do something }

If later you wanted to use detect instead of bowser, the changes in your code would be isolated to the BrowserAdapter.

UPDATE

In reality these values never change. IF you load the page in IE 9 it will never become Chrome 44. So instead of registering the BrowserAdapter as a service, just put the result in a value or constant.

angular.module('app').value('isIe9', broswerAdapter.isIe9);

I didn't want to mess with additional libraries. Simple ways suggested here didn't work out either. Finally, not on the request object, but I could get a GET parameter w/o all that hassle via self.GET.get('XXX'):

...
def get_context_data(self, **kwargs):
    context = super(SomeView, self).get_context_data(**kwargs)
    context['XXX'] = self.GET.get('XXX')

You could manually set the cookie, but depending on your use case (and if you might want to add more types of persistent/session data in future) it might make more sense to use Django's sessions feature. This will let you get and set variables tied internally to the user's session cookie. Cool thing about this is that if you want to store a lot of data tied to a user's session, storing it all in cookies will add a lot of weight to HTTP requests and responses. With sessions the session cookie is all that is sent back and forth (though there is the overhead on Django's end of storing the session data to keep in mind).

Based on different sources I have created Simple Implementation of RecyclerView using a Simple Library.

Add this line in build.gradle

implementation 'com.hereshem.lib:awesomelib:2.0.1'

AddCreate a RecyclerView by adding MyRecyclerView in activity_main.xml with

<com.hereshem.lib.recycler.MyRecyclerView
        android:id="@+id/recycler"
        app:layoutManager="LinearLayoutManager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

Now in the MainActivity, Create a ViewHolder by passing the name of Class that needs to bind

public static class EVHolder extends MyViewHolder<Events> {
    TextView date, title, summary;
    public EVHolder(View v) {
        super(v);
        date = v.findViewById(R.id.date);
        title = v.findViewById(R.id.title);
        summary = v.findViewById(R.id.summary);
    }
    @Override
    public void bindView(Events c) {
        date.setText(c.date);
        title.setText(c.title);
        summary.setText(c.summary);
    }
}

Create Items list variable and adapters with very few lines by passing items, class and layout in the adapter

List<Events> items = new ArrayList<>();
MyRecyclerView recycler = findViewById(R.id.recycler);
RecyclerViewAdapter adapter = new RecyclerViewAdapter(this, items, EVHolder.class, R.layout.row_event);
recycler.setAdapter(adapter);

ClickListener can be added with following lines

recycler.setOnItemClickListener(new MyRecyclerView.OnItemClickListener() {
    @Override
    public void onItemClick(int position) {
        Toast.makeText(MainActivity.this, "Recycler Item Clicked " + position, Toast.LENGTH_SHORT).show();
    }
});

Its all done.

More example and implementation can be found here . Hope this helps !!!

Add a background-attachment line:

#background {

    height: 100%; 
    position: absolute; 
    margin-left: 0px; 
    margin-top: 0px; 
    z-index: 0;
}

.stretch {
    width:100%;
    height:auto;
}

Products are located mainly in the following tables:

• wp_posts table with post_type like product (or product_variation),

• wp_postmeta table with post_id as relational index (the product ID).

• wp_wc_product_meta_lookup table with product_id as relational index (the post ID) | Allow fast queries on specific product data (since WooCommerce 3.7)

• wp_wc_order_product_lookuptable with product_id as relational index (the post ID) | Allow fast queries to retrieve products on orders (since WooCommerce 3.7)

Product types, categories, subcategories, tags, attributes and all other custom taxonomies are located in the following tables:

• wp_terms

• wp_termmeta

• wp_term_taxonomy

• wp_term_relationships - column object_id as relational index (the product ID)

• wp_woocommerce_termmeta

• wp_woocommerce_attribute_taxonomies (for product attributes only)

• wp_wc_category_lookup (for product categories hierarchy only since WooCommerce 3.7)

Product types are handled by custom taxonomy product_type with the following default terms:

• simple
• grouped
• variable
• external

Some other product types for Subscriptions and Bookings plugins:

• subscription
• variable-subscription
• booking

Since Woocommerce 3+ a new custom taxonomy named product_visibility handle:

• The product visibility with the terms exclude-from-search and exclude-from-catalog
• The feature products with the term featured
• The stock status with the term outofstock
• The rating system with terms from rated-1 to rated-5

Particular feature: Each product attribute is a custom taxonomy…

//Where: String^ = TextoDeBoton;
//and stdString is a "normal" string;

You can use the Apache Commons StringUtils.substring(String str, int start, int end) static method, which is also null safe.

See: http://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/StringUtils.html#substring%28java.lang.String,%20int,%20int%29

and http://commons.apache.org/proper/commons-lang/javadocs/api-2.6/src-html/org/apache/commons/lang/StringUtils.html#line.1961

Right. Better to use a function:

CREATE OR REPLACE FUNCTION yyyymm() RETURNS text
    LANGUAGE 'plpgsql' AS $$
DECLARE
    retval text;
    m integer;
BEGIN
    retval := EXTRACT(year from current_timestamp);
    m := EXTRACT(month from current_timestamp);
    IF m < 10 THEN retval := retval || '0'; END IF;
    RETURN retval || m;
END $$;

SELECT yyyymm();

DROP TABLE foo;
CREATE TABLE foo (
    key             int PRIMARY KEY,
    colname text DEFAULT yyyymm()
    );
INSERT INTO foo (key) VALUES (0);
SELECT * FROM FOO;

This gives me

 key | colname 
-----+---------
   0 | 200905

Make sure you run createlang plpgsql from the Unix command line, if necessary.

I found the problem. Instead of adding a class (.cs) file by mistake I had added a Web API Controller class which added a configuration file in my solution. And that configuration file was looking for the mentioned DLL (Microsoft.Web.Infrastructure 1.0.0.0). It worked when I removed that file, cleaned the application and then published.

My silly mistake was this: change != to ==

if(convertView != null) { // <---- HERE 
                LayoutInflater layoutInflater = LayoutInflater.from(z_selBoardElectricity.this);
                convertView = layoutInflater.inflate(R.layout.listview_board_alert, null);

                TextView textView = convertView.findViewById(R.id.board_name_tv);
                ImageView imageView = convertView.findViewById(R.id.board_imageview);

                textView.setText(text_list.get(position));
                imageView.setImageDrawable(imageAddressList.get(position));

                convertView.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Intent intent = new Intent();
                        intent.putExtra("MESSAGE", text_list.get(pos));
                        setResult(98, intent);
                        finish();
                    }
                });
            }
return convertView;

With Spring you can do:

String path = new UrlPathHelper().getPathWithinApplication(request);

This worked for me. I am using SQL Developer with Oracle DB:

ALTER TABLE YOUR_TABLE
  ADD Date_Created TIMESTAMP  DEFAULT CURRENT_TIMESTAMP NOT NULL;

You could always try the Synth look & feel. You provide an xml file that acts as a sort of stylesheet, along with any images you want to use. The code might look like this:

try {
    SynthLookAndFeel synth = new SynthLookAndFeel();
    Class aClass = MainFrame.class;
    InputStream stream = aClass.getResourceAsStream("\\default.xml");

    if (stream == null) {
        System.err.println("Missing configuration file");
        System.exit(-1);                
    }

    synth.load(stream, aClass);

    UIManager.setLookAndFeel(synth);
} catch (ParseException pe) {
    System.err.println("Bad configuration file");
    pe.printStackTrace();
    System.exit(-2);
} catch (UnsupportedLookAndFeelException ulfe) {
    System.err.println("Old JRE in use. Get a new one");
    System.exit(-3);
}

From there, go on and add your JButton like you normally would. The only change is that you use the setName(string) method to identify what the button should map to in the xml file.

The xml file might look like this:

<synth>
    <style id="button">
        <font name="DIALOG" size="12" style="BOLD"/>
        <state value="MOUSE_OVER">
            <imagePainter method="buttonBackground" path="dirt.png" sourceInsets="2 2 2 2"/>
            <insets top="2" botton="2" right="2" left="2"/>
        </state>
        <state value="ENABLED">
            <imagePainter method="buttonBackground" path="dirt.png" sourceInsets="2 2 2 2"/>
            <insets top="2" botton="2" right="2" left="2"/>
        </state>
    </style>
    <bind style="button" type="name" key="dirt"/>
</synth>

The bind element there specifies what to map to (in this example, it will apply that styling to any buttons whose name property has been set to "dirt").

And a couple of useful links:

I was wondering if/how I can 'create' a html page for each database row?

You just need to create one php file that generate an html template, what changes is the text based content on that page. In that page is where you can get a parameter (eg. row id) via POST or GET and then get the info form the database.

I'm assuming this would be better for SEO?

Search Engine as Google interpret that example.php?id=33 and example.php?id=44 are different pages, and yes, this way is better than single listing page from the SEO point of view, so you just need two php files at least (listing.php and single.php), because is better link this pages from the listing.php.

Extra advice:

example.php?id=33 is really ugly and not very seo friendly, maybe you need some url rewriting code. Something like example/properties/property-name is better ;)

Here is a function that generates Python code from a decision tree by converting the output of export_text:

import string
from sklearn.tree import export_text

def export_py_code(tree, feature_names, max_depth=100, spacing=4):
    if spacing < 2:
        raise ValueError('spacing must be > 1')

    # Clean up feature names (for correctness)
    nums = string.digits
    alnums = string.ascii_letters + nums
    clean = lambda s: ''.join(c if c in alnums else '_' for c in s)
    features = [clean(x) for x in feature_names]
    features = ['_'+x if x[0] in nums else x for x in features if x]
    if len(set(features)) != len(feature_names):
        raise ValueError('invalid feature names')

    # First: export tree to text
    res = export_text(tree, feature_names=features, 
                        max_depth=max_depth,
                        decimals=6,
                        spacing=spacing-1)

    # Second: generate Python code from the text
    skip, dash = ' '*spacing, '-'*(spacing-1)
    code = 'def decision_tree({}):\n'.format(', '.join(features))
    for line in repr(tree).split('\n'):
        code += skip + "# " + line + '\n'
    for line in res.split('\n'):
        line = line.rstrip().replace('|',' ')
        if '<' in line or '>' in line:
            line, val = line.rsplit(maxsplit=1)
            line = line.replace(' ' + dash, 'if')
            line = '{} {:g}:'.format(line, float(val))
        else:
            line = line.replace(' {} class:'.format(dash), 'return')
        code += skip + line + '\n'

    return code

Sample usage:

res = export_py_code(tree, feature_names=names, spacing=4)
print (res)

Sample output:

def decision_tree(f1, f2, f3):
    # DecisionTreeClassifier(class_weight=None, criterion='gini', max_depth=3,
    #                        max_features=None, max_leaf_nodes=None,
    #                        min_impurity_decrease=0.0, min_impurity_split=None,
    #                        min_samples_leaf=1, min_samples_split=2,
    #                        min_weight_fraction_leaf=0.0, presort=False,
    #                        random_state=42, splitter='best')
    if f1 <= 12.5:
        if f2 <= 17.5:
            if f1 <= 10.5:
                return 2
            if f1 > 10.5:
                return 3
        if f2 > 17.5:
            if f2 <= 22.5:
                return 1
            if f2 > 22.5:
                return 1
    if f1 > 12.5:
        if f1 <= 17.5:
            if f3 <= 23.5:
                return 2
            if f3 > 23.5:
                return 3
        if f1 > 17.5:
            if f1 <= 25:
                return 1
            if f1 > 25:
                return 2

The above example is generated with names = ['f'+str(j+1) for j in range(NUM_FEATURES)].

One handy feature is that it can generate smaller file size with reduced spacing. Just set spacing=2.

This will work with all versions of the .NET framework.

best and simple way is to put title inside a span and replace then.

'<div id="'+div_id+'" class="widget" style="height:60px;width:110px">\n\
        <div class="widget-head ui-widget-header" 
                style="cursor:move;height:20px;width:130px">'+
     '<span id="'+span_id+'" style="float:right; cursor:pointer" 
            class="dialog_link ui-icon ui-icon-newwin ui-icon-pencil"></span>' +
      '<span id="spTitle">'+
      dialog_title+ '</span>'
 '</div></div>

now you can simply use this:

$('#'+div_id+' .widget-head sp#spTitle').text("new dialog title");

Use this:

var arr = $('input:checkbox:checked').map(function () {
  return this.value;
}).get();

You can not use more than one Structural Directive in Angular on the same element, it makes a bad confusion and structure, so you need to apply them in 2 separate nested elements(or you can use ng-container), read this statement from Angular team:

One structural directive per host element

Someday you'll want to repeat a block of HTML but only when a particular condition is true. You'll try to put both an *ngFor and an *ngIf on the same host element. Angular won't let you. You may apply only one structural directive to an element.

The reason is simplicity. Structural directives can do complex things with the host element and its descendents. When two directives lay claim to the same host element, which one takes precedence? Which should go first, the NgIf or the NgFor? Can the NgIf cancel the effect of the NgFor? If so (and it seems like it should be so), how should Angular generalize the ability to cancel for other structural directives?

There are no easy answers to these questions. Prohibiting multiple structural directives makes them moot. There's an easy solution for this use case: put the *ngIf on a container element that wraps the *ngFor element. One or both elements can be an ng-container so you don't have to introduce extra levels of HTML.

So you can use ng-container (Angular4) as the wrapper (will be deleted from the dom) or a div or span if you have class or some other attributes as below:

<div class="right" *ngIf="show">
  <div *ngFor="let thing of stuff">
    {{log(thing)}}
    <span>{{thing.name}}</span>
  </div>
</div>

my quick answer with basic java arithmetic calculation is this:

First consider the following values:

1 Minute = 60 Seconds
1 Hour = 3600 Seconds ( 60 * 60 )
1 Day = 86400 Second ( 24 * 3600 )

1. First divide the input by 86400, if you you can get a number greater than 0 , this is the number of days. 2.Again divide the remained number you get from the first calculation by 3600, this will give you the number of hours
2. Then divide the remainder of your second calculation by 60 which is the number of Minutes
3. Finally the remained number from your third calculation is the number of seconds

the code snippet is as follows:

int input=500000;
int numberOfDays;
int numberOfHours;
int numberOfMinutes;
int numberOfSeconds;

numberOfDays = input / 86400;
numberOfHours = (input % 86400 ) / 3600 ;
numberOfMinutes = ((input % 86400 ) % 3600 ) / 60 
numberOfSeconds = ((input % 86400 ) % 3600 ) % 60  ;

I hope to be helpful to you.

According to the docs of setState() the new state might not get reflected in the callback function findRoutes(). Here is the extract from React docs:

setState() does not immediately mutate this.state but creates a pending state transition. Accessing this.state after calling this method can potentially return the existing value.

There is no guarantee of synchronous operation of calls to setState and calls may be batched for performance gains.

So here is what I propose you should do. You should pass the new states input in the callback function findRoutes().

handleFormSubmit: function(input){
    // Form Input
    this.setState({
        originId: input.originId,
        destinationId: input.destinationId,
        radius: input.radius,
        search: input.search
    });
    this.findRoutes(input);    // Pass the input here
}

The findRoutes() function should be defined like this:

findRoutes: function(me = this.state) {    // This will accept the input if passed otherwise use this.state
    if (!me.originId || !me.destinationId) {
        alert("findRoutes!");
        return;
    }
    var p1 = new Promise(function(resolve, reject) {
        directionsService.route({
            origin: {'placeId': me.originId},
            destination: {'placeId': me.destinationId},
            travelMode: me.travelMode
        }, function(response, status){
            if (status === google.maps.DirectionsStatus.OK) {
                // me.response = response;
                directionsDisplay.setDirections(response);
                resolve(response);
            } else {
                window.alert('Directions config failed due to ' + status);
            }
        });
    });
    return p1
}

Many solution here with lot of upvotes didn't work for me, even the accepted answer. I solved it by setting the scaleY, but isn't a good solution if you need too much height because the drawable comes pixelated.

Programmatically:

progressBar.setScaleY(2f);

XML Layout:

android:scaleY="2"

SELECT * FROM a WHERE a.group_id IN 
(SELECT group_id FROM b WHERE b.user_id!=$_SESSION{'[user_id']} AND b.group_id = a.group_id)
WHERE a.keyword LIKE '%".$keyword."%';

Use the re.escape() function for this:

4.2.3 re Module Contents

escape(string)

Return string with all non-alphanumerics backslashed; this is useful if you want to match an arbitrary literal string that may have regular expression metacharacters in it.

A simplistic example, search any occurence of the provided string optionally followed by 's', and return the match object.

def simplistic_plural(word, text):
    word_or_plural = re.escape(word) + 's?'
    return re.match(word_or_plural, text)

Try this:

$str = '123456789';
$char_array = preg_split('//', $str, -1, PREG_SPLIT_NO_EMPTY);

If you play the video as a playlist and then single out that video you can get it without ads. Here is what I have done: https://www.youtube.com/v/VIDEO_ID?playlist=VIDEO_ID&autoplay=1&rel=0

Surprisingly, many of the answers don't give complete working code. Here it is:

public static void createFile(String fullPath) throws IOException {
    File file = new File(fullPath);
    file.getParentFile().mkdirs();
    file.createNewFile();
}

public static void main(String [] args) throws Exception {
    String path = "C:/donkey/bray.txt";
    createFile(path);
}

Perhaps you should look at adding a Settings File. (e.g. App.Settings) Creating this file will allow you to do the following:

string mysetting = App.Default.MySetting;
App.Default.MySetting = "my new setting";

This means you can edit and then change items, where the items are strongly typed, and best of all... you don't have to touch any xml before you deploy!

The result is a Application or User contextual setting.

Have a look in the "add new item" menu for the setting file.

Old post, but here's what I did using background-size:cover; (hat tip to @Ceylan Pamir)...

If you know that the dropdownlist contains the value you're looking to select, use:

ddl.SelectedValue = "2";

If you're not sure if the value exists, use (or you'll get a null reference exception):

ListItem selectedListItem = ddl.Items.FindByValue("2");

if (selectedListItem != null)
{
    selectedListItem.Selected = true;
}

You could use a batch macro for simple capturing of command outputs, a bit like the behaviour of the bash shell.

The usage of the macro is simple and looks like

%$set% VAR=application arg1 arg2

And it works even with pipes

%$set% allDrives="wmic logicaldisk get name /value | findstr "Name""

The macro uses the variable like an array and stores each line in a separate index.
In the sample of %$set% allDrives="wmic logicaldisk there will the following variables created:

allDrives.Len=5
allDrives.Max=4
allDrives[0]=Name=C:
allDrives[1]=Name=D:
allDrives[2]=Name=F:
allDrives[3]=Name=G:
allDrives[4]=Name=Z:
allDrives=<contains the complete text with line feeds>

To use it, it's not important to understand how the macro itself works.

The full example

@echo off
setlocal

call :initMacro

%$set% ipOutput="ipconfig"
call :ShowVariable ipOutput
echo First line is %ipOutput[0]%

echo( 
%$set% driveNames="wmic logicaldisk get name /value | findstr "Name""

You can add ng-change directive to input fields. Have a look at the docs example.

If the data in your database is POSTED from HTML form TextArea controls, different browsers use different New Line characters:

Firefox separates lines with CHR(10) only

Internet Explorer separates lines with CHR(13) + CHR(10)

Apple (pre-OSX) separates lines with CHR(13) only

So you may need something like:

set col_name = replace(replace(col_name, CHR(13), ''), CHR(10), '')

os.walk can be used if you need recursion:

import os
start_path = '.' # current directory
for path,dirs,files in os.walk(start_path):
    for filename in files:
        print os.path.join(path,filename)

If you are parsing string data from the console or similar, the best way is to use regular expressions. Read more on that here: http://java.sun.com/developer/technicalArticles/releases/1.4regex/

Otherwise, to parse an int from a string, try Integer.parseInt(string). If the string is not a number, you will get an exception. Otherise you can then perform your checks on that value to make sure it is not negative.

String input;
int number;
try
{
    number = Integer.parseInt(input);
    if(number > 0)
    {
        System.out.println("You positive number is " + number);
    }
} catch (NumberFormatException ex)
{
     System.out.println("That is not a positive number!");
}

To get a character-only string, you would probably be better of looping over each character checking for digits, using for instance Character.isLetter(char).

String input
for(int i = 0; i<input.length(); i++)
{
   if(!Character.isLetter(input.charAt(i)))
   {
      System.out.println("This string does not contain only letters!");
      break;
   }
}

Good luck!

If you don't specify indexes on your initial array, you get the regular numric ones. Arrays must have some form of unique index

Filename=url.java

public class url {

    public static final String BASEURL = "http://192.168.1.122/";

}

if u want to call the variable just use this:

url.BASEURL + "your code here";

Use my Plugin :

$.fn.removeCss=function(all){
        if(all===true){
            $(this).removeAttr('class');
        }
        return $(this).removeAttr('style')
    }

For your case ,Use it as following :

$(<mySelector>).removeCss();

or

$(<mySelector>).removeCss(false);

if you want to remove also CSS defined in its classes :

$(<mySelector>).removeCss(true);

NumPy 1.7.0 (when numpy.pad was added) is pretty old now (it was released in 2013) so even though the question asked for a way without using that function I thought it could be useful to know how that could be achieved using numpy.pad.

It's actually pretty simple:

>>> import numpy as np
>>> a = np.array([[ 1.,  1.,  1.,  1.,  1.],
...               [ 1.,  1.,  1.,  1.,  1.],
...               [ 1.,  1.,  1.,  1.,  1.]])
>>> np.pad(a, [(0, 1), (0, 1)], mode='constant')
array([[ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.]])

In this case I used that 0 is the default value for mode='constant'. But it could also be specified by passing it in explicitly:

>>> np.pad(a, [(0, 1), (0, 1)], mode='constant', constant_values=0)
array([[ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.]])

Just in case the second argument ([(0, 1), (0, 1)]) seems confusing: Each list item (in this case tuple) corresponds to a dimension and item therein represents the padding before (first element) and after (second element). So:

[(0, 1), (0, 1)]
         ^^^^^^------ padding for second dimension
 ^^^^^^-------------- padding for first dimension

  ^------------------ no padding at the beginning of the first axis
     ^--------------- pad with one "value" at the end of the first axis.

In this case the padding for the first and second axis are identical, so one could also just pass in the 2-tuple:

>>> np.pad(a, (0, 1), mode='constant')
array([[ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.]])

In case the padding before and after is identical one could even omit the tuple (not applicable in this case though):

>>> np.pad(a, 1, mode='constant')
array([[ 0.,  0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.,  0.]])

Or if the padding before and after is identical but different for the axis, you could also omit the second argument in the inner tuples:

>>> np.pad(a, [(1, ), (2, )], mode='constant')
array([[ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.]])

However I tend to prefer to always use the explicit one, because it's just to easy to make mistakes (when NumPys expectations differ from your intentions):

>>> np.pad(a, [1, 2], mode='constant')
array([[ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.]])

Here NumPy thinks you wanted to pad all axis with 1 element before and 2 elements after each axis! Even if you intended it to pad with 1 element in axis 1 and 2 elements for axis 2.

I used lists of tuples for the padding, note that this is just "my convention", you could also use lists of lists or tuples of tuples, or even tuples of arrays. NumPy just checks the length of the argument (or if it doesn't have a length) and the length of each item (or if it has a length)!

Use <div class="row"> and <div class="form-group col-xs-6">

Here a fiddle :https://jsfiddle.net/core972/SMkZV/2/

List<string> myList = new List<string>();
IEnumerable<string> myEnumerable = myList;
List<string> listAgain = myEnumerable.ToList();

I couldn't get IsNothing() to behave and I didn't want to create dummy rows in my dataset (e.g. for a given list of customers create a dummy order per month displayed) and noticed that null values were displaying as -247192.

Lo and behold using that worked to suppress it (at least until MSFT changes SSRS for the better from 08R2) so forgive me but:

=iif(Fields!Sales_Diff.Value = -247192,"",Fields!Sales_Diff.Value)

item = objects.Find(obj => obj.property==myValue);

In my case the error was on a module of my project.I have resolved this with adding

dependencies {
    implementation 'com.android.support:support-v4:20.0.+'
}

this dependency in gradle of corresponding module

The DatabaseIsLocked page listed below is no longer available. The File Locking And Concurrency page describes changes related to file locking introduced in v3 and may be useful for future readers. https://www.sqlite.org/lockingv3.html

The SQLite wiki DatabaseIsLocked page offers a good explanation of this error message. It states, in part, that the source of contention is internal (to the process emitting the error).

What this page doesn't explain is how SQLite decides that something in your process holds a lock and what conditions could lead to a false positive.

If the TextFX menu does not exist, you need to download & install the plugin. Plugins->Plugin Manager->Show Plugin Manager and then check the plugin TextFX Characters. Click 'install,' restart Notepad++.

In version Notepad++ v6.1.3, I resolve with: Plugin Manager->Show Plugin Manager** and then check the plugin "Indent By Fold"

Refer below link and try to find what you really want:

ImageView.ScaleType CENTER Center the image in the view, but perform no scaling.

ImageView.ScaleType CENTER_CROP Scale the image uniformly (maintain the image's aspect ratio) so that both dimensions (width and height) of the image will be equal to or larger than the corresponding dimension of the view (minus padding).

ImageView.ScaleType CENTER_INSIDE Scale the image uniformly (maintain the image's aspect ratio) so that both dimensions (width and height) of the image will be equal to or less than the corresponding dimension of the view (minus padding).

ImageView.ScaleType FIT_CENTER Scale the image using CENTER.

ImageView.ScaleType FIT_END Scale the image using END.

ImageView.ScaleType FIT_START Scale the image using START.

ImageView.ScaleType FIT_XY Scale the image using FILL.

ImageView.ScaleType MATRIX Scale using the image matrix when drawing.

since python-daemon has not yet supported python 3.x, and from what can be read on the mailing list, it may never will, i have written a new implementation of PEP 3143: pep3143daemon

pep3143daemon should support at least python 2.6, 2.7 and 3.x

It also contains a PidFile class.

The library only depends on the standard library and on the six module.

It can be used as a drop in replacement for python-daemon.

Here is the documentation.

**IF** you are confused
 read the c# spec
**ELSE IF** you are kind of confused
 read some books
**ELSE**
 everything should be OK.

I strongly suggest you read about CSS selectors and the basics of HTML.

I faced the same issue when I had to pass a pom version to a downstream Rundeck job.

What I did, was using parameters injection via a properties file as such:

1) Creating properties in properties file via shell :

Build actions:

• Execute a shell script
• Inject environment variables

E.g : properties definition

2) Passing defined properties to the downstream job : Post Build Actions :

• Trigger parameterized build on other project
• Add parameters : Current build parameters
• Add parameters : predefined parameters

E.g : properties sending

3) It was then possible to use $POM_VERSION as such in the downstream Rundeck job.

/!\ Jenkins Version : 1.636

/!\ For some reason when creating the triggered build, it was necessary to add the option 'Current build parameters' to pass the properties.

If you want to use Parameters and regulate the maximum number of async functions you can use a simple async worker I've build:

var BackgroundWorker = function(maxTasks) {
    this.maxTasks = maxTasks || 100;
    this.runningTasks = 0;
    this.taskQueue = [];
};

/* runs an async task */
BackgroundWorker.prototype.runTask = function(task, delay, params) {
    var self = this;
    if(self.runningTasks >= self.maxTasks) {
        self.taskQueue.push({ task: task, delay: delay, params: params});
    } else {
        self.runningTasks += 1;
        var runnable = function(params) {
            try {
                task(params);
            } catch(err) {
                console.log(err);
            }
            self.taskCompleted();
        }
        // this approach uses current standards:
        setTimeout(runnable, delay, params);
    }
}

BackgroundWorker.prototype.taskCompleted = function() {
    this.runningTasks -= 1;

    // are any tasks waiting in queue?
    if(this.taskQueue.length > 0) {
        // it seems so! let's run it x)
        var taskInfo = this.taskQueue.splice(0, 1)[0];
        this.runTask(taskInfo.task, taskInfo.delay, taskInfo.params);
    }
}

You can use it like this:

var myFunction = function() {
 ...
}
var myFunctionB = function() {
 ...
}
var myParams = { name: "John" };

var bgworker = new BackgroundWorker();
bgworker.runTask(myFunction, 0, myParams);
bgworker.runTask(myFunctionB, 0, null);

If checked:

$( "SELECTOR" ).attr( "checked" )  // Returns ‘true’ if present on the element, returns undefined if not present
$( "SELECTOR" ).prop( "checked" ) // Returns true if checked, false if unchecked.
$( "SELECTOR" ).is( ":checked" ) // Returns true if checked, false if unchecked.

Get the checked val:

$( "SELECTOR:checked" ).val()

Get the checked val numbers:

$( "SELECTOR:checked" ).length

Check or uncheck checkbox

$( "SELECTOR" ).prop( "disabled", false );
$( "SELECTOR" ).prop( "checked", true );

The $.ajax() function returns a XMLHttpRequest object. Store that in a variable that's accessible from the Submit button's "OnClick" event. When a submit click is processed check to see if the XMLHttpRequest variable is:

1) null, meaning that no request has been sent yet

2) that the readyState value is 4 (Loaded). This means that the request has been sent and returned successfully.

In either of those cases, return true and allow the submit to continue. Otherwise return false to block the submit and give the user some indication of why their submit didn't work. :)

An alternative to the custom filter is to create an extension method to serialize any object to JSON.

public static class ObjectExtensions
{
    /// <summary>Serializes the object to a JSON string.</summary>
    /// <returns>A JSON string representation of the object.</returns>
    public static string ToJson(this object value)
    {
        var settings = new JsonSerializerSettings
        {
            ContractResolver = new CamelCasePropertyNamesContractResolver(),
            Converters = new List<JsonConverter> { new StringEnumConverter() }
        };

        return JsonConvert.SerializeObject(value, settings);
    }
}

Then call it when returning from the controller action.

return Content(person.ToJson(), "application/json");

It is confusing in the beginning. But it helps in the situations below :

class SomeAction implements Action {
}

// Later in the code.
Class<Action> actionClass = Class.forName("SomeAction"); 
Action action = actionClass.newInstance();
// Notice you get an Action instance, there was no need to cast.

Without changing the position to absolute, see below. This supports all recent browsers as well.

.vranger {_x000D_
  margin-top: 50px;_x000D_
   transform: rotate(270deg);_x000D_
  -moz-transform: rotate(270deg); /*do same for other browsers if required*/_x000D_
}

<input type="range" class="vranger"/>

for very old browsers, you can use -sand-transform: rotate(10deg); from CSS sandpaper

or use

prefix selector such as -ms-transform: rotate(270deg); for IE9

Pidfile contains pid of a process. It is a convention allowing long running processes to be more self-aware. Server process can inspect it to stop itself, or have heuristic that its other instance is already running. Pidfiles can also be used to conventiently kill risk manually, e.g. pkill -F <some.pid>

In addition to Optimize Imports and Auto Import, which were pointed out by @dave-newton and @ryan-stewart in earlier answers, go to:

• IDEA <= 13: File menu > Settings > Code Style > Java > Imports
• IDEA >= 14: File menu > Settings > Editor > Code Style > Java > Imports (thanks to @mathias-bader for the hint!)

There you can fine tune the grouping and order or imports, "Class count to use import with '*'", etc.

Note:
since IDEA 13 you can configure the project default settings from the IDEA "start page": Configure > Project defaults > Settings > .... Then every new project will have those default settings:

Using DISTINCT will work

SELECT GROUP_CONCAT(DISTINCT(categories) SEPARATOR ' ') FROM table
