The :query_string_normalizer option is also available, which will override the default normalizer HashConversions.to_params(query)

query_string_normalizer: ->(query){query.to_json}

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

There is no such functionality in jQuery. Use JSON.stringify or alternatively any jQuery plugin with similar functionality (e.g jquery-json).

This solution will play the video upon clicking. You'll need to edit your picture to add a button image yourself.

You're going to need the URL of your picture and the YouTube video ID. The YouTube video id is the part of the URL after the v= parameter, so for https://www.youtube.com/watch?v=DODLEX4zzLQ the ID would be DODLEX4zzLQ.

<div width="560px" height="315px" style="position: static; clear: both; width: 560px; height: 315px;">&nbsp;<div style="position: relative"><img id="vidimg" width="560px" height="315px" src="URL_TO_PICTURE" style="position: absolute; top: 0; left: 0; cursor: pointer; pointer-events: none; z-index: 2;" /><iframe id="unlocked-video" style="position: absolute; top: 0; left: 0; z-index: 1;" src="https://www.youtube.com/embed/YOUTUBE_VIDEO_ID" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe></div></div>
<script type="application/javascript">
  // Adapted from https://stackoverflow.com/a/32138108
  var monitor = setInterval(function(){
    var elem = document.activeElement;
    if(elem && elem.id == 'unlocked-video'){
      document.getElementById('vidimg').style.display='none';
      clearInterval(monitor);
    }
  }, 100);
</script>

Be sure to replace URL_TO_PICTURE and YOUTUBE_VIDEO_ID in the above snippet.

To clarify what's going on here, this displays the image on top of the video, but allows clicks to pass through the image. The script monitors for clicks in the video iframe, and then hides the image if a click occurs. You may not need the float: clear.

I haven't compared this to the other answers here, but this is what I have used.

The -std=c++14 flag is not supported on GCC 4.8. If you want to use C++14 features you need to compile with -std=c++1y. Using godbolt.org it appears that the earilest version to support -std=c++14 is GCC 4.9.0 or Clang 3.5.0

• You can customize every short cut operation according to your habbit.

Just go to Tools > Options > Environment > Keyboard > Find the action you want to set key board short-cut and change according to keyboard habbit.

How about adding an autocmd to your ~/.vimrc-file, creating a mapping:

autocmd FileType python map <buffer> <F9> :w<CR>:exec '!python3' shellescape(@%, 1)<CR>
autocmd FileType python imap <buffer> <F9> <esc>:w<CR>:exec '!python3' shellescape(@%, 1)<CR>

then you could press <F9> to execute the current buffer with python

Explanation:

• autocmd: command that Vim will execute automatically on {event} (here: if you open a python file)
• [i]map: creates a keyboard shortcut to <F9> in insert/normal mode
• <buffer>: If multiple buffers/files are open: just use the active one
• <esc>: leaving insert mode
• :w<CR>: saves your file
• !: runs the following command in your shell (try :!ls)
• %: is replaced by the filename of your active buffer. But since it can contain things like whitespace and other "bad" stuff it is better practise not to write :python %, but use:
• shellescape: escape the special characters. The 1 means with a backslash

TL;DR: The first line will work in normal mode and once you press <F9> it first saves your file and then run the file with python. The second does the same thing, but leaves insert mode first

Here is a snippet from my perl script to do this:

print OUTPUT "set arrow from $x1,$y1 to $x1,$y2 nohead lc rgb \'red\'\n";

As you might guess from above, it's actually drawn as a "headless" arrow.

Simplest solution seems to be specifying the ylim range. Here is some code to do this automatically (left default, right - adjusted):

# default y-axis
barplot(dat, beside=TRUE)

# automatically adjusted y-axis
barplot(dat, beside=TRUE, ylim=range(pretty(c(0, dat))))

The trick is to use pretty() which returns a list of interval breaks covering all values of the provided data. It guarantees that the maximum returned value is 1) a round number 2) greater than maximum value in the data.

In the example 0 was also added pretty(c(0, dat)) which makes sure that axis starts from 0.

I used the following:

delta = timedelta()
totalMinute, second = divmod(delta.seconds, 60)
hour, minute = divmod(totalMinute, 60)
print(f"{hour}h{minute:02}m{second:02}s")

You are thinking in the right direction. Merge master with mobiledevicesupport continuously and merge mobiledevicesupport with master when mobiledevicesupport is stable. Each developer will have his own branch and can merge to and from either on master or mobiledevicesupport depending on their role.

I just went through the same problem. And found out once you have a syntax or any type of error in you javascript, the whole file don't get loaded so you cannot use any of the other functions at all.

Actually you can fix it with following steps -

1. Do cls.__dict__
2. This will give you dictionary format output which will contain {'isFilled':True} or {'isFilled':False} depending upon what you have set.
3. Delete this entry - del cls.__dict__['isFilled']
4. You will be able to call the method now.

In this case, we delete the entry which overrides the method as mentioned by BrenBarn.

generally, I make by simple way, whatever, I create a restAPI endpoint for example "localhost/api/method/:lastIdObtained/:countDateToReturn" with theses parameters, you can do it a simple request. in the service, eg. .net

jsonData function(lastIdObtained,countDatetoReturn){
'... write your code as you wish..'
and into select query make a filter
select top countDatetoreturn tt.id,tt.desc
 from tbANyThing tt
where id > lastIdObtained
order by id
}

In Ionic, when I scroll from bottom to top, I pass the zero value, when I get the answer, I set the value of the last id obtained, and when I slide from top to bottom, I pass the last registration id I got

To someone who really understands how JS works this question might seem off, however most people who use JS do not have such a deep level of insight (and don't necessarily need it) and to them this is a fairly confusing point, I will try to answer from that perspective.

JS is synchronous in the way its code is executed. each line only runs after the line before it has completed and if that line calls a function after that is complete etc...

The main point of confusion arises from the fact that your browser is able to tell JS to execute more code at anytime (similar to how you can execute more JS code on a page from the console). As an example JS has Callback functions who's purpose is to allow JS to BEHAVE asynchronously so further parts of JS can run while waiting for a JS function that has been executed (I.E. a GET call) to return back an answer, JS will continue to run until the browser has an answer at that point the event loop (browser) will execute the JS code that calls the callback function.

Since the event loop (browser) can input more JS to be executed at any point in that sense JS is asynchronous (the primary things that will cause a browser to input JS code are timeouts, callbacks and events)

I hope this is clear enough to be helpful to somebody.

An ideal solution will:

1. Automatically scale to the width of the navigation container
2. Support a dynamic number of menu items.

Using a simple ul menu inside of an nav container, we can build a solution that meets the above requirements.

HTML

<nav>
  <ul>
    <li>Home</li>
    <li>About</li>
    <li>Basic Services</li>
    <li>Specialty Services</li>
    <li>Our Staff</li>
    <li>Contact Us</li>
  </ul>
</nav>

First, we need to force the ul to have the full width of its nav container. To accomplish this, we will use the :after psuedo-element with width: 100%.

This achieves our goal perfectly, but adds trailing whitespace from the psuedo-element. We can remove this whitespace across all browsers through IE8 by setting the line-height of the ul to 0 and setting it back to 100% on its li children. See the example CodePen and solution below:

CSS

nav {
  width: 900px;
}

nav ul {
  text-align: justify;
  line-height: 0;
  margin: 0;
  padding: 0;
}

nav ul:after {
  content: '';
  display: inline-block;
  width: 100%;
}

nav ul li {
  display: inline-block;
  line-height: 100%;
}

HTML CODE

<div id="borderLoader"  data-height="230px" data-color="lightgrey" data- 
width="230px" data-image="https://fiverr- res.cloudinary.com/t_profile_thumb,q_auto,f_auto/attachments/profile/photo/a54f24b2ab6f377ea269863cbf556c12-619447411516923848661/913d6cc9-3d3c-4884-ac6e-4c2d58ee4d6a.jpg">

</div>

JS CODE

var dataValue, dataSet,key;
dataValue = document.getElementById('borderLoader');
//data set contains all the dataset that you are to style the shape;
dataSet ={ 
   "height":dataValue.dataset.height,
   "width":dataValue.dataset.width,
   "color":dataValue.dataset.color,
   "imageBg":dataValue.dataset.image
};

dataValue.style.height = dataSet.height;
dataValue.style.width = dataSet.width;
dataValue.style.background = "#f3f3f3 url("+dataSet.imageBg+") no-repeat 
center";

      def remove_duplicates_thenSort():
         t = ['b', 'c', 'd','d','a','c','c']
         t2 = []
         for i,k in enumerate(t):
              index = t.index(k)
              if i == index:
                 t2.append(t[i])
         return sorted(t2)
      print(remove_duplicates_thenSort())

On the one hand, throwing exceptions is inherently expensive, because the stack has to be unwound etc.
On the other hand, accessing a value in a dictionary by its key is cheap, because it's a fast, O(1) operation.

BTW: The correct way to do this is to use TryGetValue

obj item;
if(!dict.TryGetValue(name, out item))
    return null;
return item;

This accesses the dictionary only once instead of twice.
If you really want to just return null if the key doesn't exist, the above code can be simplified further:

obj item;
dict.TryGetValue(name, out item);
return item;

This works, because TryGetValue sets item to null if no key with name exists.

You can write following codes to achieve this task:

SELECT ... FROM ... WHERE ... 
INTO OUTFILE 'textfile.csv'
FIELDS TERMINATED BY '|'

It export the result to CSV and then export it to excel sheet.

your maximum, minimum method is right

but you don't print int to console!

and... maybe better location change (maximum, minimum) methods

now (maximum, minimum) methods in the roop. it is need not.. just need one call

i suggest change this code

    for (int i = 0 ; i < array.length; i++ ) {
       int next = input.nextInt();
       // sentineil that will stop loop when 999 is entered
       if (next == 999)
       break;
       array[i] = next;
}
System.out.println("max Value : " + getMaxValue(array));
System.out.println("min Value : " + getMinValue(array));
System.out.println("These are the numbers you have entered.");
printArray(array);

Run Spring Boot app using Maven

You can also use Maven plugin to run your Spring Boot app. Use the below example to run your Spring Boot app with Maven plugin:

mvn spring-boot:run

Run Spring Boot App with Gradle

And if you use Gradle you can run the Spring Boot app with the following command:

gradle bootRun

I agree with @maverik above, I prefer not to hide the details with a typedef. Especially when you are trying to understand what is going on. I also prefer to see everything instead of a partial code snippet. With that said, here is a malloc and free of a complex structure.

Pretty simple but another said you dont pass session variables through the url bar 1.You dont need to because a session is passed throughout the whole website from header when you put in header file 2.security risks
Here is first page code

$url = "http://localhost/main.php?email=" . urlencode($email_address) . "&eventid=" . urlencode($event_id);

2nd page when getting the variables from the url bar is:

if(isset($_GET['email']) && !empty($_GET['email']) AND isset($_GET['eventid']) && !empty($_GET['eventid'])){ ////do whatever here }

Now if you want to do it the proper way of using the session you created then ignore my above code and call the session variables on the second page for instance create a session on the first page lets say for example:

 $_SESSION['WEB_SES'] = $email_address . "^" . $event_id;

obvious that you would have already assigned values to the session variables in the code above, you can call the session name whatever you want to i just used the example web_ses , the second page all you need to do is start a session and see if the session is there and check the variables and do whatever with them, example:

 session_start();
 if (isset($_SESSION['WEB_SES'])){
 $Array = explode("^", $_SESSION['WEB_SES']);
 $email = $Array[0];
 $event_id = $Array[1]
 echo "$email";
 echo "$event_id";
 }

Like I said before the good thing about sessions are they can be carried throughout the entire website if this type of code in put in the header file that gets called upon on all pages that load, you can simple use the variable wherever and whenever. Hope this helps :)

One possible reason could be you have upgraded the some of your projects (in the solution) to higher version e.g. from .NET 4.0 to 4.5 This happened in my case when I opened the solution in VS 2013 (originally created using VS 2010 and .NET 4.0). When I opened in VS 2013 my C++ project got updated to .NET 4.5 and I started to see the problem.

In Python mutable objects are passed as reference, so you can pass a reference of the outer class to the inner class.

class OuterClass:
    def __init__(self):
        self.outer_var = 1
        self.inner_class = OuterClass.InnerClass(self)
        print('Inner variable in OuterClass = %d' % self.inner_class.inner_var)

    class InnerClass:
        def __init__(self, outer_class):
            self.outer_class = outer_class
            self.inner_var = 2
            print('Outer variable in InnerClass = %d' % self.outer_class.outer_var)

It's not possible, opacity is inherited by child nodes and you can't avoid this. To have only the parent transparent, you have to play with positioning (absolute) of the elements and their z-index

pi Radians = 180 degrees

So 1 degree = pi/180 radians

or 1 radian = 180/pi degrees

Necromancing.
I assume when somebody lands here, he needs a foreign key to column in a table that contains non-unique keys.

The problem is, that if you have that problem, the database-schema is denormalized.

You're for example keeping rooms in a table, with a room-uid primary key, a DateFrom and a DateTo field, and another uid, here RM_ApertureID to keep track of the same room, and a soft-delete field, like RM_Status, where 99 means 'deleted', and <> 99 means 'active'.

So when you create the first room, you insert RM_UID and RM_ApertureID as the same value as RM_UID. Then, when you terminate the room to a date, and re-establish it with a new date range, RM_UID is newid(), and the RM_ApertureID from the previous entry becomes the new RM_ApertureID.

So, if that's the case, RM_ApertureID is a non-unique field, and so you can't set a foreign-key in another table.

And there is no way to set a foreign key to a non-unique column/index, e.g. in T_ZO_REM_AP_Raum_Reinigung (WHERE RM_UID is actually RM_ApertureID).
But to prohibit invalid values, you need to set a foreign key, otherwise, data-garbage is the result sooner rather than later...

Now what you can do in this case (short of rewritting the entire application) is inserting a CHECK-constraint, with a scalar function checking the presence of the key:

IF  EXISTS (SELECT * FROM sys.check_constraints WHERE object_id = OBJECT_ID(N'[dbo].[Check_RM_ApertureIDisValid_T_ZO_REM_AP_Raum_Reinigung]') AND parent_object_id = OBJECT_ID(N'[dbo].[T_ZO_REM_AP_Raum_Reinigung]'))

    try { // checks code for exceptions
        WebElement ele=
        (WebElement)wait.until(ExpectedConditions.elementToBeClickable((By.xpath(Xpath))));

  background:blue;
  width:30%;
  min-height:20px;
  max-height:60px;

Try this by yourself.

Connecting to any mysql database should be like this:

$mysql -h hostname -Pportnumber -u username -p (then enter)

Then it will ask for password. Note: Port number should be closer to -P or it will show error. Make sure you know what is your mysql port. Default is 3306 and is optional to specify the port in this case. If its anything else you need to mention port number with -P or else it will show error.

For example: $mysql -h 10.20.40.5 -P3306 -u root -p (then enter)

Password:My_Db_Password

Gubrish about product you using.

mysql>_

Note: If you are trying to connect a db at different location make sure you can ping to that server/computer.

$ping 10.20.40.5

It should return TTL with time you got back PONG. If it says destination unreachable then you cannot connect to remote mysql no matter what.

In such case contact your Network Administrator or Check your cable connection to your computer till the end of your target computer. Or check if you got LAN/WAN/MAN or internet/intranet/extranet working.

You have to use target attribute

int is used to declare primitive variable

e.g. int i=10;

Integer is used to create reference variable of class Integer

Integer a = new Integer();

Although adequate answers have already been given, I'd like to propose a less verbose solution, that can be used without the helper methods available in an MVC controller class. Using a third party library called "RazorEngine" you can use .Net file IO to get the contents of the razor file and call

string html = Razor.Parse(razorViewContentString, modelObject);

If you need to add two strings together which are very large numbers you'll need to evaluate the addition at every string position:

function addStrings(str1, str2){
  str1a = str1.split('').reverse();
  str2a = str2.split('').reverse();
  let output = '';
  let longer = Math.max(str1.length, str2.length);
  let carry = false;
  for (let i = 0; i < longer; i++) {
    let result
    if (str1a[i] && str2a[i]) {
      result = parseInt(str1a[i]) + parseInt(str2a[i]);

    } else if (str1a[i] && !str2a[i]) {
      result = parseInt(str1a[i]);

    } else if (!str1a[i] && str2a[i]) {
      result = parseInt(str2a[i]);
    }

    if (carry) {
        result += 1;
        carry = false;
    }
    if(result >= 10) {
      carry = true;
      output += result.toString()[1];
    }else {
      output += result.toString();
    }
  }
  output = output.split('').reverse().join('');

  if(carry) {
    output = '1' + output;
  }
  return output;
}

For covering my case -> I've got a range start & end date, and dates list that can be as partly in provided range, as fully (overlapping).

Solution covered with tests:

/**
 * Check has any of quote work days in provided range.
 *
 * @param startDate inclusively
 * @param endDate   inclusively
 *
 * @return true if any in provided range inclusively
 */
public boolean hasAnyWorkdaysInRange(LocalDate startDate, LocalDate endDate) {
    if (CollectionUtils.isEmpty(workdays)) {
        return false;
    }

    LocalDate firstWorkDay = getFirstWorkDay().getDate();
    LocalDate lastWorkDay = getLastWorkDay().getDate();

    return (firstWorkDay.isBefore(endDate) || firstWorkDay.equals(endDate))
            && (lastWorkDay.isAfter(startDate) || lastWorkDay.equals(startDate));
}

This solution working for me

I have connection string Server=(localdb)\v11.0;Integrated Security=true;Database=DB1;

But many people say .NET 4.0.2 or 4.5 is required.

If you want to build Java EE applications, it's best to use Eclipse IDE for Java EE. It has editors from HTML to JSP/JSF, Javascript. It's rich for webapps development, and provide plugins and tools to develop Java EE applications easily (all bundled).

Eclipse Classic is basically the full featured Eclipse without the Java EE part.

Lots of hate for the Convert class here... Just to balance a little bit, there is one advantage for Convert - if you are handed an object,

Convert.ToDouble(o);

can just return the value easily if o is already a Double (or an int or anything readily castable).

Using Double.Parse or Double.TryParse is great if you already have it in a string, but

Double.Parse(o.ToString());

has to go make the string to be parsed first and depending on your input that could be more expensive.

I always do it like this:

$("#id").css("width", "50%");

// use: clone( <thing to copy> ) returns <new copy>
// untested use at own risk
function clone(o, m){
  // return non object values
  if('object' !==typeof o) return o
  // m: a map of old refs to new object refs to stop recursion
  if('object' !==typeof m || null ===m) m =new WeakMap()
  var n =m.get(o)
  if('undefined' !==typeof n) return n
  // shallow/leaf clone object
  var c =Object.getPrototypeOf(o).constructor
  // TODO: specialize copies for expected built in types i.e. Date etc
  switch(c) {
    // shouldn't be copied, keep reference
    case Boolean:
    case Error:
    case Function:
    case Number:
    case Promise:
    case String:
    case Symbol:
    case WeakMap:
    case WeakSet:
      n =o
      break;
    // array like/collection objects
    case Array:
      m.set(o, n =o.slice(0))
      // recursive copy for child objects
      n.forEach(function(v,i){
        if('object' ===typeof v) n[i] =clone(v, m)
      });
      break;
    case ArrayBuffer:
      m.set(o, n =o.slice(0))
      break;
    case DataView:
      m.set(o, n =new (c)(clone(o.buffer, m), o.byteOffset, o.byteLength))
      break;
    case Map:
    case Set:
      m.set(o, n =new (c)(clone(Array.from(o.entries()), m)))
      break;
    case Int8Array:
    case Uint8Array:
    case Uint8ClampedArray:
    case Int16Array:
    case Uint16Array:
    case Int32Array:
    case Uint32Array:
    case Float32Array:
    case Float64Array:
      m.set(o, n =new (c)(clone(o.buffer, m), o.byteOffset, o.length))
      break;
    // use built in copy constructor
    case Date:
    case RegExp:
      m.set(o, n =new (c)(o))
      break;
    // fallback generic object copy
    default:
      m.set(o, n =Object.assign(new (c)(), o))
      // recursive copy for child objects
      for(c in n) if('object' ===typeof n[c]) n[c] =clone(n[c], m)
  }
  return n
}

At this moment there is a method to do this directly on the request object:

request.setTimeout(timeout, function() {
    request.abort();
});

This is a shortcut method that binds to the socket event and then creates the timeout.

Basically:

$lastDate = date("Y-m-t", strtotime($query_d));

Date t parameter return days number in current month.

you can use winhttprequest object instead of internet explorer as it's good to load data excluding pictures n advertisement instead of downloading full webpage including advertisement n pictures those make internet explorer object heavy compare to winhttpRequest object.

I guess the problem is that you need to start a separate thread for each connection and call serverSocket.accept() in a loop to accept more than one connection.

It is not a problem to have more than one connection on the same port.

This error can happen when, in IIS Manager, the ASP.NET MVC site is pointed to the wrong directory.

In my case, I inadvertently had the site pointed to the solution directory instead of the child project directory. That is, I had the site's Physical path set to

C:\dev\MySolution

instead of

C:\dev\MySolution\MyProject.

Specific steps to fix this:

1. Open IIS Manager (Start > Run > inetmgr);
2. In IIS Manager, in the left pane, expand Sites;
3. Under Sites, left-click the ASP.NET MVC website;
4. In the right pane, click Basic Settings...;
5. In the Edit Site dialog, change the Physical path to the project directory.
6. Click OK.

I don't understand why some people are suggesting using cross apply or outer apply to convert the xml into a table of values. For me, that just brought back way too much data.

Here's my example of how you'd create an xml object, then turn it into a table.

(I've added spaces in my xml string, just to make it easier to read.)

DECLARE @str nvarchar(2000)

SET @str = ''
SET @str = @str + '<users>'
SET @str = @str + '  <user>'
SET @str = @str + '     <firstName>Mike</firstName>'
SET @str = @str + '     <lastName>Gledhill</lastName>'
SET @str = @str + '     <age>31</age>'
SET @str = @str + '  </user>'
SET @str = @str + '  <user>'
SET @str = @str + '     <firstName>Mark</firstName>'
SET @str = @str + '     <lastName>Stevens</lastName>'
SET @str = @str + '     <age>42</age>'
SET @str = @str + '  </user>'
SET @str = @str + '  <user>'
SET @str = @str + '     <firstName>Sarah</firstName>'
SET @str = @str + '     <lastName>Brown</lastName>'
SET @str = @str + '     <age>23</age>'
SET @str = @str + '  </user>'
SET @str = @str + '</users>'

DECLARE @xml xml
SELECT @xml = CAST(CAST(@str AS VARBINARY(MAX)) AS XML) 

--  Iterate through each of the "users\user" records in our XML
SELECT 
    x.Rec.query('./firstName').value('.', 'nvarchar(2000)') AS 'FirstName',
    x.Rec.query('./lastName').value('.', 'nvarchar(2000)') AS 'LastName',
    x.Rec.query('./age').value('.', 'int') AS 'Age'
FROM @xml.nodes('/users/user') as x(Rec)

And here's the output:

In case you are using extending the dialog the use:

requestWindowFeature(Window.FEATURE_NO_TITLE);

You can either

1) Declare printMenu(), getUserchoice() and input as static

OR

2) If you want to design it better, move the logic from your main into a separate instance method. And then from the main create a new instance of your class and call your instance method(s)

For anyone who came here looking for how to get the true accordion effect and only allow one row to be expanded at a time, you can add an event handler for show.bs.collapse like so:

$('.collapse').on('show.bs.collapse', function () {
    $('.collapse.in').collapse('hide');
});

I modified this example to do so here: http://jsfiddle.net/QLfMU/116/

DELETE FROM blob 
WHERE fileid NOT IN 
       (SELECT id 
        FROM files 
        WHERE id is NOT NULL/*This line is unlikely to be needed 
                               but using NOT IN...*/
      )

Following @Tobu answer and @mipadi comment, in a more pythonic way, if not interested in the created flag, I would use:

customer.source, _ = Source.objects.get_or_create(name="Website")

From the documentation:

Named exports are useful to export several values. During the import, one will be able to use the same name to refer to the corresponding value.

Concerning the default export, there is only a single default export per module. A default export can be a function, a class, an object or anything else. This value is to be considered as the "main" exported value since it will be the simplest to import.

You have three options:

• Style links to look like buttons using CSS.

  Just look at the light blue "tags" under your question.

  It is possible, even to give them a depressed appearance when clicked (using pseudo-classes like :active), without any scripting. Lots of major sites, such as Google, are starting to make buttons out of CSS styles these days anyway, scripting or not.

• Put a separate <form> element around each one.

  As you mentioned in the question. Easy and will definitely work without Javascript (or even CSS). But it adds a little extra code which may look untidy.

• Rely on Javascript.

  Which is what you said you didn't want to do.

Yes, you are correct. If you are using a jQuery plugin, do not put the code in the controller. Instead create a directive and put the code that you would normally have inside the link function of the directive.

There are a couple of points in the documentation that you could take a look at. You can find them here:
Common Pitfalls

Using controllers correctly

Ensure that when you are referencing the script in your view, you refer it last - after the angularjs library, controllers, services and filters are referenced.

EDIT: Rather than using $(element), you can make use of angular.element(element) when using AngularJS with jQuery

Two ways:

results = results.Where(o => (o.OrderStatus == OrderStatus.Open) &&
                             (o.CustomerID == customerID));

or:

results = results.Where(o => (o.OrderStatus == OrderStatus.Open))
                 .Where(o => (o.CustomerID == customerID));

I usually prefer the latter. But it's worth profiling the SQL server to check the query execution and see which one performs better for your data (if there's any difference at all).

A note about chaining the .Where() methods: You can chain together all the LINQ methods you want. Methods like .Where() don't actually execute against the database (yet). They defer execution until the actual results are calculated (such as with a .Count() or a .ToList()). So, as you chain together multiple methods (more calls to .Where(), maybe an .OrderBy() or something to that effect, etc.) they build up what's called an expression tree. This entire tree is what gets executed against the data source when the time comes to evaluate it.

Step 1: Get HttpURLConnection object

URL url = new URL(urlToConnect);
HttpURLConnection httpUrlConnection = (HttpURLConnection) url.openConnection();

Step 2: Add headers to the HttpURLConnection using setRequestProperty method.

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

headers.put("X-CSRF-Token", "fetch");
headers.put("content-type", "application/json");

for (String headerKey : headers.keySet()) {
    httpUrlConnection.setRequestProperty(headerKey, headers.get(headerKey));
}

php artisan config:clear   

(NOT cache)

select * from emp where sal =(select max(sal) from emp where eno in(select eno from emp where sal <(select max(sal)from emp )));

try the above code ....

if you want the third max record then add another nested query "select max(sal)from emp" inside the bracket of the last query and give less than operator in front of it.

Shouldn't it simply be:

<button ng-click="clickingCallback()">Click me<button>

Why do you want to write a new directive just to map your click event to a callback on your scope ? ng-click already does that for you.

Using jQuery, you can do:

$("input:text").each(function ()
{
    // store default value
    var v = this.value;

    $(this).blur(function ()
    {
        // if input is empty, reset value to default 
        if (this.value.length == 0) this.value = v;
    }).focus(function ()
    {
        // when input is focused, clear its contents
        this.value = "";
    }); 
});

And you could stuff all this into a custom plug-in, like so:

jQuery.fn.hideObtrusiveText = function ()
{
    return this.each(function ()
    {
        var v = this.value;

        $(this).blur(function ()
        {
            if (this.value.length == 0) this.value = v;
        }).focus(function ()
        {
            this.value = "";
        }); 
    });
};

Here's how you would use the plug-in:

$("input:text").hideObtrusiveText();

Advantages to using this code is:

• Its unobtrusive and doesn't pollute the DOM
• Code re-use: it works on multiple fields
• It figures out the default value of inputs by itself

Non-jQuery approach:

function hideObtrusiveText(id)
{
    var e = document.getElementById(id);

    var v = e.value;

    e.onfocus = function ()
    {
        e.value = "";
    };

    e.onblur = function ()
    {
        if (e.value.length == 0) e.value = v;
    };
}

Maybe not very elegant, but it does the job:

exec(open("script.py").read())

List(Of String) will handle that, mostly - though you need to either use AddRange to add a collection of items, or Add to add one at a time:

lstOfString.Add(String1)
lstOfString.Add(String2)
lstOfString.Add(String3)
lstOfString.Add(String4)

If you're adding known values, as you show, a good option is to use something like:

Dim inputs() As String = { "some value", _
                              "some value2", _
                              "some value3", _
                              "some value4" }

Dim lstOfString as List(Of String) = new List(Of String)(inputs)

' ...
Dim s3 = lstOfStrings(3)

This will still allow you to add items later as desired, but also get your initial values in quickly.

Edit:

In your code, you need to fix the declaration. Change:

Dim lstWriteBits() As List(Of String) 

To:

Dim lstWriteBits As List(Of String) 

Currently, you're declaring an Array of List(Of String) objects.

Just document it here on Windows you need to escape the \ character:

"e:\\directory\\-"

I have recently faced the same issue. I wrote the following code:

    $('html').click(function(e) {
      var a = e.target;
      if ($(a).parents('.menu_container').length === 0) {
        $('.ofSubLevelLinks').removeClass('active'); //hide menu item
        $('.menu_container li > img').hide(); //hide dropdown image, if any
     }
    });

It has worked for me perfectly.

Use toArray(T[] a) method:

String[] array = set.toArray(new String[0]);

The Random class of Java located in the java.util package will serve your purpose better. It has some nextInt() methods that return an integer. The one taking an int argument will generate a number between 0 and that int, the latter not inclusive.

In my case this happened because there's was a manifest merger error and I was trying to run the app. Look at the specific error by running Build->Make Project

For most Microsoft products (Internet Explorer, Office, "open file" dialogs etc) you can register an application to be run when URI with appropriate prefix is opened. This is a part of more common explanation - how to implement your own protocol.

For Mozilla the explanation is here, Java - here.

There is a built in method for this:

byte[] data = { 1, 2, 4, 8, 16, 32 };

string hex = BitConverter.ToString(data);

Result: 01-02-04-08-10-20

If you want it without the dashes, just remove them:

string hex = BitConverter.ToString(data).Replace("-", string.Empty);

Result: 010204081020

If you want a more compact representation, you can use Base64:

string base64 = Convert.ToBase64String(data);

Result: AQIECBAg

I found this more useful for getting the absolute file location.

File file = new File("\\TestHello\\test.txt");
System.out.println(file.getAbsoluteFile());

Remove Quote. and use innerText instead of text

function toggleText(button_id) 
{                      //-----\/ 'button_id' - > button_id
   if (document.getElementById(button_id).innerText == "Lock") 
   {
       document.getElementById(button_id).innerText = "Unlock";
   }
   else 
   {
     document.getElementById(button_id).innerText = "Lock";
   }
}

Using John W answer I created an implementation that correctly begin the timeout when the task starts its execution. I even write a unit test for it :)

However, it does not suit my needs since some IO operations do not interrupt when Future.cancel() is called (ie when Thread.interrupt() is called). Some examples of IO operation that may not be interrupted when Thread.interrupt() is called are Socket.connect and Socket.read (and I suspect most of IO operation implemented in java.io). All IO operations in java.nio should be interruptible when Thread.interrupt() is called. For example, that is the case for SocketChannel.open and SocketChannel.read.

Anyway if anyone is interested, I created a gist for a thread pool executor that allows tasks to timeout (if they are using interruptible operations...): https://gist.github.com/amanteaux/64c54a913c1ae34ad7b86db109cbc0bf

JDBC is a much lower-level (and older) specification than JPA. In it's bare essentials, JDBC is an API for interacting with a database using pure SQL - sending queries and retrieving results. It has no notion of objects or hierarchies. When using JDBC, it's up to you to translate a result set (essentially a row/column matrix of values from one or more database tables, returned by your SQL query) into Java objects.

Now, to understand and use JDBC it's essential that you have some understanding and working knowledge of SQL. With that also comes a required insight into what a relational database is, how you work with it and concepts such as tables, columns, keys and relationships. Unless you have at least a basic understanding of databases, SQL and data modelling you will not be able to make much use of JDBC since it's really only a thin abstraction on top of these things.

You can also patern :

DF[DF.col.str.contains(pat = '(foo)', regex = True) ]

Thats the natural behavior of the buttons. You could try putting a max-width/max-height on the parent container, but I'm not sure if that would do it.

max-width:something px;
max-height:something px;

The other option would be to use the devlopr tools and see if you can remove the natural padding.

padding: 0;

This works in Python 2.x.

For Python 3 look in the docs:

import urllib.request

with urllib.request.urlopen("http://www.python.org") as url:
    s = url.read()
    # I'm guessing this would output the html source code ?
    print(s)

Not exactly the case of this question but can be helpful. I got this exception when i call mkdirs() on new file instead of its parent

File file = new java.io.File(path);
//file.mkdirs(); // wrong! 
file.getParentFile().mkdirs(); // correct!
if (!file.exists()) {
    file.createNewFile();
} 

If you are working with MVC C#, this is the way to deal with printers and serial ports for dropdowns.

using System.Collections.Generic;
using System.Linq;
using System.IO.Ports;
using System.Drawing.Printing;

    public class Miclass
    {
        private void AllViews()
        {
            List<PortClass> ports = new List<PortClass>();
            List<Printersclass> Printersfor = new List<Printersclass>();
            string[] portnames = SerialPort.GetPortNames();
            /*PORTS*/
            for (int i = 0; i < portnames.Count(); i++)
            {
                ports.Add(new PortClass() { Name = portnames[i].Trim(), Desc = portnames[i].Trim() });
            }
            /*PRINTER*/
            for (int i = 0; i < PrinterSettings.InstalledPrinters.Count; i++)
            {
                Printersfor.Add(new Printersclass() { Name = PrinterSettings.InstalledPrinters[i].Trim(), Desc = PrinterSettings.InstalledPrinters[i].Trim() });
            }
        }
    }
    public class PortClass
    {
        public string Name { get; set; }
        public string Desc { get; set; }

        public override string ToString()
        {
            return string.Format("{0} ({1})", Name, Desc);
        }
    }
    public class Printersclass
    {
        public string Name { get; set; }
        public string Desc { get; set; }

        public override string ToString()
        {
            return string.Format("{0} ({1})", Name, Desc);
        }
    }

1) Add the following line to /etc/security/limits.conf

webuser hard nofile 64000

then login as webuser

su - webuser

2) Edit following two files for webuser

append .bashrc and .bash_profile file by running

echo "ulimit -n 64000" >> .bashrc ; echo "ulimit -n 64000" >> .bash_profile

3) Log out, then log back in and verify that the changes have been made correctly:

$ ulimit -a | grep open
open files                      (-n) 64000

Thats it and them boom, boom boom.

What is the meaning of parameter -1?

You can read -1 as dynamic number of parameters or "anything". Because of that there can be only one parameter -1 in view().

If you ask x.view(-1,1) this will output tensor shape [anything, 1] depending on the number of elements in x. For example:

import torch
x = torch.tensor([1, 2, 3, 4])
print(x,x.shape)
print("...")
print(x.view(-1,1), x.view(-1,1).shape)
print(x.view(1,-1), x.view(1,-1).shape)

Will output:

tensor([1, 2, 3, 4]) torch.Size([4])
...
tensor([[1],
        [2],
        [3],
        [4]]) torch.Size([4, 1])
tensor([[1, 2, 3, 4]]) torch.Size([1, 4])

• You can use copy con to write a long text

I'm on Catalina and I got this error:

touch: /usr/local/Homebrew/.git/FETCH_HEAD: Permission denied
touch: /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask/.git/FETCH_HEAD: Permission denied
fatal: Unable to create '/usr/local/Homebrew/.git/index.lock': Permission denied

I only needed to chown the Homebrew directory

sudo chown -R "$USER":admin /usr/local/Homebrew

Try

use an id for hidden field and use id of checkbox in javascript.

and change the ClientIDMode="static" too

<input type="hidden" ClientIDMode="static" id="label1" name="label206451" value="0" />

   <script type="text/javascript"> 
    var cb = document.getElementById('txt206451');
    var label = document.getElementById('label1');
    cb.addEventListener('click',function(evt){
    if(cb.checked){
        label.value='Thanks'
    }else{
        label.value='0'
    }
    },false);
    </script>

One possible way is to do something like this:

public class MyThread extends Thread {
    @Override
    public void run() {
        while (!this.isInterrupted()) {
            //
        }
    }
}

And when you want to stop your thread, just call a method interrupt():

myThread.interrupt();

Of course, this won't stop thread immediately, but in the following iteration of the loop above. In the case of downloading, you need to write a non-blocking code. It means, that you will attempt to read new data from the socket only for a limited amount of time. If there are no data available, it will just continue. It may be done using this method from the class Socket:

mySocket.setSoTimeout(50);

In this case, timeout is set up to 50 ms. After this time has gone and no data was read, it throws an SocketTimeoutException. This way, you may write iterative and non-blocking thread, which may be killed using the construction above.

It's not possible to kill thread in any other way and you've to implement such a behavior yourself. In past, Thread had some method (not sure if kill() or stop()) for this, but it's deprecated now. My experience is, that some implementations of JVM doesn't even contain that method currently.

I had the same issue.

Look at your git ignore and check if .env is not ignored.

It was my problem and resolved to my case.

Pickle serializes a single object at a time, and reads back a single object - the pickled data is recorded in sequence on the file.

If you simply do pickle.load you should be reading the first object serialized into the file (not the last one as you've written).

After unserializing the first object, the file-pointer is at the beggining of the next object - if you simply call pickle.load again, it will read that next object - do that until the end of the file.

objects = []
with (open("myfile", "rb")) as openfile:
    while True:
        try:
            objects.append(pickle.load(openfile))
        except EOFError:
            break

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

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

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

The answer is no, but for me I did the following

the script: myExport

#! \bin\bash
export $1

an alias in my .bashrc

alias myExport='source myExport' 

Still you source it, but maybe in this way it is more useable and it is interesting for someone else.

Since phone numbers must conform to a pattern, you can use regular expressions to match the entered phone number against the pattern you define in regexp.

php has both ereg and preg_match() functions. I'd suggest using preg_match() as there's more documentation for this style of regex.

An example

$phone = '000-0000-0000';

if(preg_match("/^[0-9]{3}-[0-9]{4}-[0-9]{4}$/", $phone)) {
  // $phone is valid
}

Here the defination of Rendersection from MSDN

In layout pages, renders the content of a named section.MSDN

In _layout.cs page put

@RenderSection("Bottom",false)

Here render the content of bootom section and specifies false boolean property to specify whether the section is required or not.

@section Bottom{
       This message form bottom.
}

That meaning if you want to bottom section in all pages, then you must use false as the second parameter at Rendersection method.

Working with floats is bit messy:

This as many other 'trivial' layout tricks can be done with flexbox.

   div.container {
     display: flex;
     justify-content: space-between;
   }

In 2017 I think this is preferred solution (over float) if you don't have to support legacy browsers: https://caniuse.com/#feat=flexbox

Check fiddle how different float usages compares to flexbox ("may include some competing answers"): https://jsfiddle.net/b244s19k/25/. If you still need to stick with float I recommended third version of course.

it can be useful : If you want to do it with Symfony forms :

 $today = new DateTime('now');
 $formBuilder->add('startDate', DateType::class, array(
                   'widget' => 'single_text',
                   'data'   => new \DateTime(),
                   'attr'   => ['min' => $today->format('Y-m-d')]
                   ));

Here's how I do file upload in react using axios

import React from 'react'
import axios, { post } from 'axios';

class SimpleReactFileUpload extends React.Component {

  constructor(props) {
    super(props);
    this.state ={
      file:null
    }
    this.onFormSubmit = this.onFormSubmit.bind(this)
    this.onChange = this.onChange.bind(this)
    this.fileUpload = this.fileUpload.bind(this)
  }

  onFormSubmit(e){
    e.preventDefault() // Stop form submit
    this.fileUpload(this.state.file).then((response)=>{
      console.log(response.data);
    })
  }

  onChange(e) {
    this.setState({file:e.target.files[0]})
  }

  fileUpload(file){
    const url = 'http://example.com/file-upload';
    const formData = new FormData();
    formData.append('file',file)
    const config = {
        headers: {
            'content-type': 'multipart/form-data'
        }
    }
    return  post(url, formData,config)
  }

  render() {
    return (
      <form onSubmit={this.onFormSubmit}>
        <h1>File Upload</h1>
        <input type="file" onChange={this.onChange} />
        <button type="submit">Upload</button>
      </form>
   )
  }
}



export default SimpleReactFileUpload

I've been working on something similar and after a few tries and fails came up with this:

Example: STRING-TO-TEST-ON = 'ab,cd,ef,gh'

I wanted to extract everything after the last occurrence of "," (comma) from the string... resulting in "gh".

My query is:

SELECT SUBSTR('ab,cd,ef,gh' FROM (LENGTH('ab,cd,ef,gh') - (LOCATE(",",REVERSE('ab,cd,ef,gh'))-1)+1)) AS `wantedString`

Now let me try and explain what I did ...

1. I had to find the position of the last "," from the string and to calculate the wantedString length, using LOCATE(",",REVERSE('ab,cd,ef,gh'))-1 by reversing the initial string I actually had to find the first occurrence of the "," in the string ... which wasn't hard to do ... and then -1 to actually find the string length without the ",".

2. calculate the position of my wantedString by subtracting the string length I've calculated at 1st step from the initial string length:

   LENGTH('ab,cd,ef,gh') - (LOCATE(",",REVERSE('ab,cd,ef,gh'))-1)+1

I have (+1) because I actually need the string position after the last "," .. and not containing the ",". Hope it makes sense.

3. all it remain to do is running a SUBSTR on my initial string FROM the calculated position.

I haven't tested the query on large strings so I do not know how slow it is. So if someone actually tests it on a large string I would very happy to know the results.

Your question didnt ask how to use BETWEEN correctly, rather asked for help with the unexpectedly truncated results...

As mentioned/hinting at in the other answers, the problem is that you have time segments in addition to the dates.

In my experience, using date diff is worth the extra wear/tear on the keyboard. It allows you to express exactly what you want, and you are covered.

select * 
from xxx 
where datediff(d, '2012-10-26', dates) >=0
and  datediff(d, dates,'2012-10-27') >=0

using datediff, if the first date is before the second date, you get a positive number. There are several ways to write the above, for instance always having the field first, then the constant. Just flipping the operator. Its a matter of personal preference.

you can be explicit about whether you want to be inclusive or exclusive of the endpoints by dropping one or both equal signs.

BETWEEN will work in your case, because the endpoints are both assumed to be midnight (ie DATEs). If your endpoints were also DATETIME, using BETWEEN may require even more casting. In my mind DATEDIFF was put in our lives to insulate us from those issues.

I'm afraid that's not possible. the rgba format you know is the only one.

How can I accomplish that?

Your example declares a TypeScript < 1.5 internal module, which is now called a namespace. The old module App {} syntax is now equivalent to namespace App {}. As a result, the following works:

// test.ts
export namespace App {
    export class SomeClass {
        getName(): string {
            return 'name';
        }
    }
}

// main.ts
import { App } from './test';
var a = new App.SomeClass();

That being said...

Try to avoid exporting namespaces and instead export modules (which were previously called external modules). If needs be you can use a namespace on import with the namespace import pattern like this:

// test.ts
export class SomeClass {
    getName(): string {
        return 'name';
    }
}

// main.ts
import * as App from './test'; // namespace import pattern
var a = new App.SomeClass();

This error popped up several times on several different projects.

What I finally figured out is that when I would build, there was already a copy of the system.web.mvc binary assembly in my bin folder.

To fix this, right-click on the assembly in the list of references and select "properties". Check to see if this is the latest version by looking at the "Version" property. If it is, switch "Copy Local" to true.

This will make sure that the version referenced in your project is the version that will end up in your binaries folder.

If you still get the error, try running nuGet to get the latest version, then try the aforementioned again.

Good luck - this error is a pain!

Hope the below example will help,

echo ${name:0:$((${#name}-10))} --> ${name:start:len}

• In above command, name is the variable.
• start is the string starting point
• len is the length of string that has to be removed.

Example:

    read -p "Enter:" name
    echo ${name:0:$((${#name}-10))}

Output:

    Enter:Siddharth Murugan
    Siddhar

Note: Bash 4.2 added support for negative substring

This is great article and conversation. I tried to use the ternary operator as described. But the code didn't work resulting in an error as mentioned.

Column(children: [ condition? Text("True"): null,],);

The ternary example above is miss leading. Dart will respond with an error that a null was returned instead of widget. You can't return null. The correct way will be to return a widget:

Column(children: [ condition? Text("True"): Text("false"),],); 

In order for the ternary to work you need to return a Widget. If you don't want to return anything you can return a empty container.

Column(children: [ condition? Text("True"): Container(),],); 

Good luck.

After hours of trying, the function is born :) I had a scenario where I had to display loader in time while the file is preparing for download:

Working in Chrome, Safari and Firefox

function ajaxDownload(url, filename = 'file', method = 'get', data = {}, callbackSuccess = () => {}, callbackFail = () => {}) {
    $.ajax({
        url: url,
        method: 'GET',
        xhrFields: {
            responseType: 'blob'
        },
        success: function (data) {
            // create link element
            let a = document.createElement('a'), 
                url = window.URL.createObjectURL(data);

            // initialize 
            a.href = url;
            a.download = filename;

            // append element to the body, 
            // a must, due to Firefox
            document.body.appendChild(a);

            // trigger download
            a.click();

            // delay a bit deletion of the element
            setTimeout(function(){
                window.URL.revokeObjectURL(url);
                document.body.removeChild(a);
            }, 100);

            // invoke callback if any 
            callbackSuccess(data);
        },
        error: function (err) {
            // invoke fail callback if any
            callbackFail(err)
        }
    });

My case was to print horizontal (landscape) summary section - so:

}).then((canvas) => {
  const img = canvas.toDataURL('image/jpg');
  new jsPDF({
        orientation: 'l', // landscape
        unit: 'pt', // points, pixels won't work properly
        format: [canvas.width, canvas.height] // set needed dimensions for any element
  });
  pdf.addImage(img, 'JPEG', 0, 0, canvas.width, canvas.height);
  pdf.save('your-filename.pdf');
});

Similar to what Mark E has proposed, you have to come up with your own. Just to help you a bit, there is a neat article http://gleichmann.wordpress.com/2008/01/15/building-your-own-literals-in-java-tuples-and-maps/ which gives you a really neat way of creating tuples and maps that might be something you might want to consider.

While the accepted answer is correct, I'll add a more elegant version (in my opinion):

boolean idExists = tabPane.getTabs().stream()
    .map(Tab::getId)
    .anyMatch(idToCheck::equals);

Don't neglect using Stream#map() which allows to flatten the data structure before applying the Predicate.

To have a consistent flow of the images on different devices, you'd have to specify the width and height value for each carousel image item, for instance here in my example the image would take the full width but with a height of "400px" (you can specify your personal value instead)

<div class="item">
        <img src="image.jpg" style="width:100%; height: 400px;">
      </div>

Use:

    SELECT t1.id, 
           t1.parent_id, 
           t1.name,
           t2.name AS parent_name,
           t2.id AS parent_id
      FROM tbl t1
 LEFT JOIN tbl t2 ON t2.id = t1.parent_id
START WITH t1.id = 1 
CONNECT BY PRIOR t1.id = t1.parent_id

Here is a simple method (If you don't bother about how it works!!!)

Use findspark

1. Go to your python shell

   pip install findspark
   
   import findspark
   findspark.init()
   

2. import the necessary modules

   from pyspark import SparkContext
   from pyspark import SparkConf
   

3. Done!!!

If you want to update your listview doesn't matter if you want to do that on onResume(), onCreate() or in some other function, first thing that you have to realize is that you won't need to create a new instance of the adapter, just populate the arrays with your data again. The idea is something similar to this :

private ArrayList<String> titles;
private MyListAdapter adapter;
private ListView myListView;

@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main_activity);

    myListView = (ListView) findViewById(R.id.my_list);

    titles = new ArrayList<String>()

    for(int i =0; i<20;i++){
        titles.add("Title "+i);
    }

    adapter = new MyListAdapter(this, titles);
    myListView.setAdapter(adapter);
}


@Override
public void onResume(){
    super.onResume();
    // first clear the items and populate the new items
    titles.clear();
    for(int i =0; i<20;i++){
        titles.add("New Title "+i);
    }
    adapter.notifySetDataChanged();
}

So depending on that answer you should use the same List<Item> in your Fragment. In your first adapter initialization you fill your list with the items and set adapter to your listview. After that in every change in your items you have to clear the values from the main List<Item> items and than populate it again with your new items and call notifySetDataChanged();.

That's how it works : ).

Even shorter and with json-functions:

JSONObject songsObject = json.getJSONObject("songs");
JSONArray songsArray = songsObject.toJSONArray(songsObject.names());

So try this out (x == true) ^ (x == false) note you need the parenthesis but this is more beautiful and compact.

It even passes the suggested like "cuak" but not a "cuak"... class X; def !; self end end ; x = X.new; (x == true) ^ (x == false)

Note: See that this is so basic that you can use it in other languages too, that doesn't provide a "thing is boolean".

Note 2: Also you can use this to say thing is one of??: "red", "green", "blue" if you add more XORS... or say this thing is one of??: 4, 5, 8, 35.

Please read the example in rfc6749 sec 7.1 first.

The bearer token is a type of access token, which does NOT require PoP(proof-of-possession) mechanism.

PoP means kind of multi-factor authentication to make access token more secure. ref

Proof-of-Possession refers to Cryptographic methods that mitigate the risk of Security Tokens being stolen and used by an attacker. In contrast to 'Bearer Tokens', where mere possession of the Security Token allows the attacker to use it, a PoP Security Token cannot be so easily used - the attacker MUST have both the token itself and access to some key associated with the token (which is why they are sometimes referred to 'Holder-of-Key' (HoK) tokens).

Maybe it's not the case, but I would say,

• access token = payment methods
• bearer token = cash
• access token with PoP mechanism = credit card (signature or password will be verified, sometimes need to show your ID to match the name on the card)

BTW, there's a draft of "OAuth 2.0 Proof-of-Possession (PoP) Security Architecture" now.

Actually, I'd like to improve on Anton's answer.

Since getItemViewType(int position) returns an integer value, you can return the layout resource ID you'd need to inflate. That way you'd save some logic in onCreateViewHolder(ViewGroup parent, int viewType) method.

Also, I wouldn't suggest doing intensive calculations in getItemCount() as that particular function is called at least 5 times while rendering the list, as well as while rendering each item beyond the visible items. Sadly since notifyDatasetChanged() method is final, you can't really override it, but you can call it from another function within the adapter.

I just stumbled upon this question and here is an update for Swift 3 and iOS 10:

let testUIBarButtonItem = UIBarButtonItem(image: UIImage(named: "test.png"), style: .plain, target: self, action: nil)
self.navigationItem.rightBarButtonItem  = testUIBarButtonItem

It is definitely much faster than creating the UIButton with all the properties and then subsequently adding the customView to the UIBarButtonItem.

And if you want to change the color of the image from the default blue to e.g. white, you can always change the tint color:

test.tintColor = UIColor.white()

PS You should obviously change the selector etc. for your app :)

not() is a function in xpath (as opposed to an operator), so

//a[not(contains(@id, 'xx'))]

Generally speaking, for a production web application, you will want to put your node.js app behind a lightweight reverse proxy such as nginx or lighttpd. Among the many benefits of this setup, you can configure the reverse proxy to do http compression or even tls compression, without having to change your application source code.

I don't believe this is possible. Consider the following example:

>>> a = []
>>> b = a
>>> id(a)
140031712435664
>>> id(b)
140031712435664

The a and b point to the same object, but the object can't know what variables point to it.

You can use resolve:

angular.module('app',[])
.config(function($routeProvider)
{
    $routeProvider
    .when('/', {
        templateUrl  : 'app/views/login.html',
        controller   : 'YourController',
        controllerAs : 'Your',
        resolve: {
            factory : checkLoginRedirect
        }
    })
}

And, the function of the resolve:

function checkLoginRedirect($location){

    var user = firebase.auth().currentUser;

    if (user) {
        // User is signed in.
        if ($location.path() == "/"){
            $location.path('dash'); 
        }

        return true;
    }else{
        // No user is signed in.
        $location.path('/');
        return false;
    }   
}

Firebase also has a method that helps you install an observer, I advise installing it inside a .run:

.run(function(){

    firebase.auth().onAuthStateChanged(function(user) {
        if (user) {
            console.log('User is signed in.');
        } else {
            console.log('No user is signed in.');
        }
    });
  }

Close to your solution would be this:

var largest = 0
for (i <- 999 to 1 by -1;
  j <- i to 1 by -1;
  product = i * j;
  if (largest <= product && product.toString.reverse.equals (product.toString.reverse.reverse)))
    largest = product

println (largest)

The j-iteration is made without a new scope, and the product-generation as well as the condition are done in the for-statement (not a good expression - I don't find a better one). The condition is reversed which is pretty fast for that problem size - maybe you gain something with a break for larger loops.

String.reverse implicitly converts to RichString, which is why I do 2 extra reverses. :) A more mathematical approach might be more elegant.

Correct Answer here

Create class with name MyApp like below:

public class MyApp implements Application.ActivityLifecycleCallbacks, ComponentCallbacks2 {

    private Context context;
    public void setContext(Context context)
    {
        this.context = context;
    }

    private boolean isInBackground = false;

    @Override
    public void onTrimMemory(final int level) {
        if (level == ComponentCallbacks2.TRIM_MEMORY_UI_HIDDEN) {


            isInBackground = true;
            Log.d("status = ","we are out");
        }
    }


    @Override
    public void onActivityCreated(Activity activity, Bundle bundle) {

    }

    @Override
    public void onActivityStarted(Activity activity) {

    }

    @Override
    public void onActivityResumed(Activity activity) {

        if(isInBackground){

            isInBackground = false;
            Log.d("status = ","we are in");
        }

    }

    @Override
    public void onActivityPaused(Activity activity) {

    }

    @Override
    public void onActivityStopped(Activity activity) {

    }

    @Override
    public void onActivitySaveInstanceState(Activity activity, Bundle bundle) {

    }

    @Override
    public void onActivityDestroyed(Activity activity) {

    }

    @Override
    public void onConfigurationChanged(Configuration configuration) {

    }

    @Override
    public void onLowMemory() {

    }
}

Then, everywhere you want (better first activity launched in app), add the code below:

MyApp myApp = new MyApp();
registerComponentCallbacks(myApp);
getApplication().registerActivityLifecycleCallbacks(myApp);

Done! Now when the app is in the background, we get log status : we are out and when we go in app, we get log status : we are out

When passing parameters through the URL you're able to retrieve the values as GET parameters.

Use this:

$variable = $_GET['param_name'];

//Or as you have it
$ppc = $_GET['ppc'];

It is safer to check for the variable first though:

if (isset($_GET['ppc'])) {
  $ppc = $_GET['ppc'];
} else {
  //Handle the case where there is no parameter
}

Here's a bit of reading on GET/POST params you should look at: http://php.net/manual/en/reserved.variables.get.php

EDIT: I see this answer still gets a lot of traffic years after making it. Please read comments attached to this answer, especially input from @emc who details a WordPress function which accomplishes this goal securely.

The verbose configuration option might allow you to see what you want. There is an example in the documentation.

NOTE: Read the comments below: The verbose config options doesn't seem to be available anymore.

To set the class when clicking on a div immediately within the .container element, you could use:

<script>
$('.container>div').click(function () {
        $(this).addClass('whatever')
    });
</script>

First of all, the easiest way to run things at startup is to add them to the file /etc/rc.local.

Another simple way is to use @reboot in your crontab. Read the cron manpage for details.

However, if you want to do things properly, in addition to adding a script to /etc/init.d you need to tell ubuntu when the script should be run and with what parameters. This is done with the command update-rc.d which creates a symlink from some of the /etc/rc* directories to your script. So, you'd need to do something like:

update-rc.d yourscriptname start 2

However, real init scripts should be able to handle a variety of command line options and otherwise integrate to the startup process. The file /etc/init.d/README has some details and further pointers.

The simplest way that doesn't require third party libraries it to create a URL object and then call either openConnection or openStream on it. Note that this is a pretty basic API, so you won't have a lot of control over the headers.

var dataArray = [];
var obj = jQuery.parseJSON(response);
  for( key in obj ) 
  dataArray.push([key.toString(), obj [key]]);
};

The big difference is, substr() is a deprecated method that can still be used, but should be used with caution because they are expected to be removed entirely sometime in the future. You should work to remove their use from your code. And the substring() method succeeded and specified the former one.

Here you go: ES5

var test = 'Hello World';
if( test.indexOf('World') >= 0){
  // Found world
}

With ES6 best way would be to use includes function to test if the string contains the looking work.

const test = 'Hello World';
if (test.includes('World')) { 
  // Found world
}

I have also faced this issue when my window service started throwing the exception

System.UnauthorizedAccessException: Access to the path "C:\\Order\\Media
44aa4857-3bac-4a18-a307-820450361662.mp4" is denied.

So as a solution, I checked the user account associated with my service, as shown in below screen capture

So in my case it was NETWORK SERVICE

And then went to the folder properties to check if the associated user account also exists under their permission tab. It was missing in my case and when I added it and it fixed my issue.

For more information please check the below screen capture

Just type like "correct" case

"wrong"

git config --global mike.email "[email protected]"
git config --global mike.name  "mike"

"correct"

git config --global user.email "[email protected]"    
git config --global user.name "mike"

user.name is your account name in git-hub user.email is your email when you sign in git-hub.

The time() function displays the seconds between now and the unix epoch , 01 01 1970 (00:00:00 GMT). The strtotime() transforms a normal date format into a time() format. So the representation of that date into seconds will be : 1388516401

So I'm a pretty critical person, and figure if I'm going to invest in a library, I'd better know what I'm getting myself into. I figure it's better to go heavy on the criticism and light on the flattery when scrutinizing; what's wrong with it has many more implications for the future than what's right. So I'm going to go overboard here a little bit to provide the kind of answer that would have helped me and I hope will help others who may journey down this path. Keep in mind that this is based on what little reviewing/testing I've done with these libs. Oh and I stole some of the positive description from Reed.

I'll mention up top that I went with GMTL despite it's idiosyncrasies because the Eigen2 unsafeness was too big of a downside. But I've recently learned that the next release of Eigen2 will contain defines that will shut off the alignment code, and make it safe. So I may switch over.

Update: I've switched to Eigen3. Despite it's idiosyncrasies, its scope and elegance are too hard to ignore, and the optimizations which make it unsafe can be turned off with a define.

Eigen2/Eigen3

Benefits: LGPL MPL2, Clean, well designed API, fairly easy to use. Seems to be well maintained with a vibrant community. Low memory overhead. High performance. Made for general linear algebra, but good geometric functionality available as well. All header lib, no linking required.

Idiocyncracies/downsides: (Some/all of these can be avoided by some defines that are available in the current development branch Eigen3)

• Unsafe performance optimizations result in needing careful following of rules. Failure to follow rules causes crashes.
  • you simply cannot safely pass-by-value
  • use of Eigen types as members requires special allocator customization (or you crash)
  • use with stl container types and possibly other templates required special allocation customization (or you will crash)
  • certain compilers need special care to prevent crashes on function calls (GCC windows)

GMTL

Benefits: LGPL, Fairly Simple API, specifically designed for graphics engines. Includes many primitive types geared towards rendering (such as planes, AABB, quatenrions with multiple interpolation, etc) that aren't in any other packages. Very low memory overhead, quite fast, easy to use. All header based, no linking necessary.

Idiocyncracies/downsides:

• API is quirky
  • what might be myVec.x() in another lib is only available via myVec[0] (Readability problem)
    • an array or stl::vector of points may cause you to do something like pointsList[0][0] to access the x component of the first point
  • in a naive attempt at optimization, removed cross(vec,vec) and replaced with makeCross(vec,vec,vec) when compiler eliminates unnecessary temps anyway
  • normal math operations don't return normal types unless you shut off some optimization features e.g.: vec1 - vec2 does not return a normal vector so length( vecA - vecB ) fails even though vecC = vecA - vecB works. You must wrap like: length( Vec( vecA - vecB ) )
  • operations on vectors are provided by external functions rather than members. This may require you to use the scope resolution everywhere since common symbol names may collide
  • you have to do
      length( makeCross( vecA, vecB ) )
    or
      gmtl::length( gmtl::makeCross( vecA, vecB ) )
    where otherwise you might try
      vecA.cross( vecB ).length()
    

• not well maintained
  • still claimed as "beta"
  • documentation missing basic info like which headers are needed to use normal functionalty
    • Vec.h does not contain operations for Vectors, VecOps.h contains some, others are in Generate.h for example. cross(vec&,vec&,vec&) in VecOps.h, [make]cross(vec&,vec&) in Generate.h

• immature/unstable API; still changing.
  • For example "cross" has moved from "VecOps.h" to "Generate.h", and then the name was changed to "makeCross". Documentation examples fail because still refer to old versions of functions that no-longer exist.

NT2

Can't tell because they seem to be more interested in the fractal image header of their web page than the content. Looks more like an academic project than a serious software project.

Latest release over 2 years ago.

Apparently no documentation in English though supposedly there is something in French somewhere.

Cant find a trace of a community around the project.

LAPACK & BLAS

Benefits: Old and mature.

Downsides:

• old as dinosaurs with really crappy APIs

Flex Solution

It is perfectly fine if you want to go with the display: table-cell solution. But instead of hacking it out, we have a better way to accomplish the same using display: flex;. flex is something which has a decent support.

.wrap {_x000D_
  height: 200px;_x000D_
  width: 200px;_x000D_
  border: 1px solid #aaa;_x000D_
  margin: 10px;_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
.wrap span {_x000D_
  align-self: flex-end;_x000D_
}

<div class="wrap">_x000D_
  <span>Align me to the bottom</span>_x000D_
</div>

In the above example, we first set the parent element to display: flex; and later, we use align-self to flex-end. This helps you push the item to the end of the flex parent.

Old Solution (Valid if you are not willing to use flex)

If you want to align the text to the bottom, you don't have to write so many properties for that, using display: table-cell; with vertical-align: bottom; is enough

div {_x000D_
  display: table-cell;_x000D_
  vertical-align: bottom;_x000D_
  border: 1px solid #f00;_x000D_
  height: 100px;_x000D_
  width: 100px;_x000D_
}

<div>Hello</div>

(Or JSFiddle)

We added some WCF SOAP related things to an existing IIS site and it caused this problem, with the site refusing to honour the web.config authentication redirect.

We tried the various fixes listed without success, and invented a work around of mapping the new weird URL back to the one we've been using for years:

<urlMappings enabled="true">
<add mappedUrl="~/loginout.aspx" url="~/Account/Login"/>
</urlMappings>

That worked but it's ugly. Eventually we traced it down to a web.config entry added by Visual Studio some time earlier:

<add key="webpages:Enabled" value="true" />

As we'd been unable to work out precisely what that does, we took it out, which solved the problem for us immediately.

Toastr is a very nice component, and you can show messages with theses commands:

// for success - green box
toastr.success('Success messages');

// for errors - red box
toastr.error('errors messages');

// for warning - orange box
toastr.warning('warning messages');

// for info - blue box
toastr.info('info messages');

If you want to provide a title on the toastr message, just add a second argument:

// for info - blue box
toastr.success('The process has been saved.', 'Success');

you also can change the default behaviour using something like this:

toastr.options.timeOut = 3000; // 3s

See more on the github of the project.

Edits

A sample of use:

$(document).ready(function() {

    // show when page load
    toastr.info('Page Loaded!');

    $('#linkButton').click(function() {
       // show when the button is clicked
       toastr.success('Click Button');

    });

});

and a html:

<a id='linkButton'>Show Message</a>

Since none of the answers above actually explain what happened, I decided to chime in and bring some more details to this issue.

Yes, the solution is to run the MySQL Upgrade command, as follows: mysql_upgrade -u root -p --force, but what happened?

The root cause for this issue is the corruption of performance_schema, which can be caused by:

• Organic corruption (volumes going kaboom, engine bug, kernel driver issue etc)
• Corruption during mysql Patch (it is not unheard to have this happen during a mysql patch, specially for major version upgrades)
• A simple "drop database performance_schema" will obviously cause this issue, and it will present the same symptoms as if it was corrupted

This issue might have been present on your database even before the patch, but what happened on MySQL 5.7.8 specifically is that the flag show_compatibility_56 changed its default value from being turned ON by default, to OFF. This flag controls how the engine behaves on queries for setting and reading variables (session and global) on various MySQL Versions.

Because MySQL 5.7+ started to read and store these variables on performance_schema instead of on information_schema, this flag was introduced as ON for the first releases to reduce the blast radius of this change and to let users know about the change and get used to it.

OK, but why does the connection fail? Because depending on the driver you are using (and its configuration), it may end up running commands for every new connection initiated to the database (like show variables, for instance). Because one of these commands can try to access a corrupted performance_schema, the whole connection aborts before being fully initiated.

So, in summary, you may (it's impossible to tell now) have had performance_schema either missing or corrupted before patching. The patch to 5.7.8 then forced the engine to read your variables out of performance_schema (instead of information_schema, where it was reading it from because of the flag being turned ON). Since performance_schema was corrupted, the connections are failing.

Running MySQL upgrade is the best approach, despite the downtime. Turning the flag on is one option, but it comes with its own set of implications as it was pointed out on this thread already.

Both should work, but weight the consequences and know your choices :)

Using regex to validate IP address is a bad idea - this will pass 999.999.999.999 as valid. Try this approach using socket instead - much better validation and just as easy, if not easier to do.

import socket

def valid_ip(address):
    try: 
        socket.inet_aton(address)
        return True
    except:
        return False

print valid_ip('10.10.20.30')
print valid_ip('999.10.20.30')
print valid_ip('gibberish')

If you really want to use parse-the-host approach instead, this code will do it exactly:

def valid_ip(address):
    try:
        host_bytes = address.split('.')
        valid = [int(b) for b in host_bytes]
        valid = [b for b in valid if b >= 0 and b<=255]
        return len(host_bytes) == 4 and len(valid) == 4
    except:
        return False

Walkthough on what is MUL, PRI and UNI in MySQL?

From the MySQL 5.7 documentation:

• If Key is PRI, the column is a PRIMARY KEY or is one of the columns in a multiple-column PRIMARY KEY.
• If Key is UNI, the column is the first column of a UNIQUE index. (A UNIQUE index permits multiple NULL values, but you can tell whether the column permits NULL by checking the Null field.)
• If Key is MUL, the column is the first column of a nonunique index in which multiple occurrences of a given value are permitted within the column.

Live Examples

Control group, this example has neither PRI, MUL, nor UNI:

mysql> create table penguins (foo INT);
Query OK, 0 rows affected (0.01 sec)

Thanks to Ging3r i got solution:

follow these steps:

1. don't use in dependency tag. Use following in dependencies tag in pom.xml file::

   <dependency>
   <groupId>com.netsuite.suitetalk.proxy.v2019_1</groupId>
   <artifactId>suitetalk-axis-proxy-v2019_1</artifactId>
   <version>1.0.0</version>
   </dependency>
   <dependency>
       <groupId>com.netsuite.suitetalk.client.v2019_1</groupId>
       <artifactId>suitetalk-client-v2019_1</artifactId>
       <version>2.0.0</version>
   </dependency>
   <dependency>

       <artifactId>suitetalk-client-common</artifactId>

2. use following code in plugins tag in pom.xml file:

I am including 3 jars from lib folder:

Finally, use mvn clean and then mvn install or 'mvn clean install' and just run jar file from target folder or the path where install(see mvn install log):

java -jar abc.jar

note: Remember one thing if you are working at jenkins then first use mvn clean and then mvn clean install command work for you because with previous code mvn clean install command store cache for dependency.

Using paste command:

paste -d, -s file

You can use mongo --eval 'printjson(db.getCollectionNames())' to get the list of collections and then do a mongoexport on all of them. Here is an example in ruby

  out = `mongo  #{DB_HOST}/#{DB_NAME} --eval "printjson(db.getCollectionNames())"`

  collections = out.scan(/\".+\"/).map { |s| s.gsub('"', '') }

  collections.each do |collection|
    system "mongoexport --db #{DB_NAME}  --collection #{collection}  --host '#{DB_HOST}' --out #{collection}_dump"
  end

I am assuming that you are trying to remove a single file from git tacking. for that I would recommend below command.

git update-index --assume-unchanged

Ex - git update-index --assume-unchanged .gitignore .idea/compiler.xml

Position the cursor inside the class, then press ALT + Ins and select Getters and Setters from the contextual menu.

The definitions for NP complete problems above is correct, but I thought I might wax lyrical about their philosophical importance as nobody has addressed that issue yet.

Almost all complex problems you'll come up against will be NP Complete. There's something very fundamental about this class, and which just seems to be computationally different from easily solvable problems. They sort of have their own flavour, and it's not so hard to recognise them. This basically means that any moderately complex algorithm is impossible for you to solve exactly -- scheduling, optimising, packing, covering etc.

But not all is lost if a problem you'll encounter is NP Complete. There is a vast and very technical field where people study approximation algorithms, which will give you guarantees for being close to the solution of an NP complete problem. Some of these are incredibly strong guarantees -- for example, for 3sat, you can get a 7/8 guarantee through a really obvious algorithm. Even better, in reality, there are some very strong heuristics, which excel at giving great answers (but no guarantees!) for these problems.

Note that two very famous problems -- graph isomorphism and factoring -- are not known to be P or NP.

I had this error for my XXX element and it was because my XSD was wrongly formatted according to javax.xml.bind v2.2.11 . I think it's using an older XSD format but I didn't bother to confirm.

My initial wrong XSD was alike the following:

<xs:element name="Document" type="Document"/>
...
<xs:complexType name="Document">
    <xs:sequence>
        <xs:element name="XXX" type="XXX_TYPE"/>
    </xs:sequence>
</xs:complexType>

The good XSD format for my migration to succeed was the following:

<xs:element name="Document">
    <xs:complexType>
        <xs:sequence>
            <xs:element ref="XXX"/>
        </xs:sequence>
    </xs:complexType>        
</xs:element>
...
<xs:element name="XXX" type="XXX_TYPE"/>

And so on for every similar XSD nodes.

A blanket "no you shouldn't" is terrible advice. This is perfectly reasonable in many situations depending on your use case, workload, data entropy, hardware, etc.. What you shouldn't do is make assumptions.

It should be noted that you can specify a prefix which will limit MySQL's indexing, thereby giving you some help in narrowing down the results before scanning the rest. This may, however, become less useful over time as your prefix "fills up" and becomes less unique.

It's very simple to do, e.g.:

CREATE TABLE IF NOT EXISTS `foo` (
  `id` varchar(128),
  PRIMARY KEY (`id`(4))
)

Also note that the prefix (4) appears after the column quotes. Where the 4 means that it should use the first 4 characters of the 128 possible characters that can exist as the id.

Lastly, you should read how index prefixes work and their limitations before using them: https://dev.mysql.com/doc/refman/8.0/en/create-index.html

Didn't see this here

System.Web.HttpUtility.JavaScriptStringEncode("Hello, this is Satan's Site")

it was the only thing that worked (asp 4.0+) when dealing with html like this. The' gets rendered as ' (using htmldecode) in the html, causing it to fail:

<a href="article.aspx?id=268" onclick="tabs.open('modules/xxx/id/268', 'It&apos;s Allstars'); return false;">It's Allstars</a>

The EclipsePasteAsJavaString plug-in allows you to insert text as a Java string by Ctrl + Shift + V

Example

Paste as usual via Ctrl+V:

some text with tabs and new lines

Paste as Java string via Ctrl+Shift+V

"some text\twith tabs\r\n" + "and new \r\n" + "lines"

\p{L} matches a single code point in the category "letter".
\p{N} matches any kind of numeric character in any script.

Source: regular-expressions.info

If you're going to work with regular expressions a lot, I'd suggest bookmarking that site, it's very useful.

I feel I need to clarify one very important thing, for others (like my co-worker) who came across this thread and got the wrong information.

The answer given ("Try decimal(9,2) or decimal(10,2) or whatever.") is correct, but the reason ("increase the number of digits before the decimal") is wrong.

decimal(p,s) and numeric(p,s) both specify a Precision and a Scale. The "precision" is not the number of digits to the left of the decimal, but instead is the total precision of the number.

For example: decimal(2,1) covers 0.0 to 9.9, because the precision is 2 digits (00 to 99) and the scale is 1. decimal(4,1) covers 000.0 to 999.9 decimal(4,2) covers 00.00 to 99.99 decimal(4,3) covers 0.000 to 9.999

How can I push my tag to the remote repository so that all client computers can see it?

Run this to push mytag to your git origin (eg: GitHub or GitLab)

git push origin refs/tags/mytag

It's better to use the full "refspec" as shown above (literally refs/tags/mytag) just in-case mytag is actually v1.0.0 and is ambiguous (eg: because there's a branch also named v1.0.0).

I was looking for a way to debug code in a WordPress plugin that I was developing and came across this post.

I took the bits of code that are most applicable to me from other responses and combined these into a function that I can use for debugging WordPress. The function is:

function debug_log($object=null, $label=null, $priority=1) {
    $priority = $priority<1? 1: $priority;
    $message = json_encode($object, JSON_PRETTY_PRINT);
    $label = "Debug" . ($label ? " ($label): " : ': ');
    echo "<script>console.log('" . str_repeat("-", $priority-1) . $label . "', " . $message . ");</script>";
}

Usage is as follows:

$txt = 'This is a test string';
$sample_array = array('cat', 'dog', 'pig', 'ant', 'fly');
debug_log($txt, '', 7);
debug_log($sample_array);

If this function is used with WordPress development, the function should be placed in the functions.php file of the child theme and can then be called anywhere in the code.

Another method is by using the menu within visual studio. Project -> Add Reference... I recommend copying the needed .dll to your resource folder, or local project folder.

The difference is between testing the problem and the solution. Software is a solution to a problem, both can be tested.

The functional test confirms the software performs a function within the boundaries of how you've solved the problem. This is an integral part of developing software, comparable to the testing that is done on mass produced product before it leaves the factory. A functional test verifies that the product actually works as you (the developer) think it does.

Acceptance tests verify the product actually solves the problem it was made to solve. This can best be done by the user (customer), for instance performing his/her tasks that the software assists with. If the software passes this real world test, it's accepted to replace the previous solution. This acceptance test can sometimes only be done properly in production, especially if you have anonymous customers (e.g. a website). Thus a new feature will only be accepted after days or weeks of use.

Functional testing - test the product, verifying that it has the qualities you've designed or build (functions, speed, errors, consistency, etc.)

Acceptance testing - test the product in its context, this requires (simulation of) human interaction, test it has the desired effect on the original problem(s).

If you have numpy installed you can try:

data = numpy.asarray(im)

(I say "try" here, because it's unclear why getdata() isn't working for you, and I don't know whether asarray uses getdata, but it's worth a test.)

Try adding 2 spaces (or a backslash \) after the first line:

[Name of link](url)
My line of text\

Visually:

[Name of link](url)<space><space>
My line of text\

Output:

<p><a href="url">Name of link</a><br>
My line of text<br></p>

you could use inherit

#one {width:500px;height:300px;}
#two {width:inherit;height:inherit;}
#three {width:inherit;height:inherit;}

I'd like to give my give my practice.

Use your preferred IDE, take eclipse for for example here:

1. Find an appropriate location within the exception stack
2. Set conditional breakpoint
3. Debug it
4. It will print the corrupted jar before exception

Try a different encoding such as Encoding.UTF8. You can also try letting StreamReader find the encoding itself:

    StreamReader reader = new StreamReader(inputFilePath, System.Text.Encoding.UTF8, true)

Edit: Just saw your update. Try letting StreamReader do the guessing.

public string ReplaceFirst(string text, string search, string replace)
{
  int pos = text.IndexOf(search);
  if (pos < 0)
  {
    return text;
  }
  return text.Substring(0, pos) + replace + text.Substring(pos + search.Length);
}

here is an Extension Method that could also work as well per VoidKing request

public static class StringExtensionMethods
{
    public static string ReplaceFirst(this string text, string search, string replace)
    {
      int pos = text.IndexOf(search);
      if (pos < 0)
      {
        return text;
      }
      return text.Substring(0, pos) + replace + text.Substring(pos + search.Length);
    }
}

To squash using grafts

Add a file .git/info/grafts, put there the commit hash you want to become your root

git log will now start from that commit

sys.exit is the canonical way to exit.

Internally sys.exit just raises SystemExit. However, calling sys.exitis more idiomatic than raising SystemExit directly.

os.exit is a low-level system call that exits directly without calling any cleanup handlers.

quit and exit exist only to provide an easy way out of the Python prompt. This is for new users or users who accidentally entered the Python prompt, and don't want to know the right syntax. They are likely to try typing exit or quit. While this will not exit the interpreter, it at least issues a message that tells them a way out:

>>> exit
Use exit() or Ctrl-D (i.e. EOF) to exit
>>> exit()
$

This is essentially just a hack that utilizes the fact that the interpreter prints the __repr__ of any expression that you enter at the prompt.

nohup some_command > /dev/null 2>&1&

That's all you need to do!

What the error is telling, is that you can't convert an entire list into an integer. You could get an index from the list and convert that into an integer:

x = ["0", "1", "2"] 
y = int(x[0]) #accessing the zeroth element

If you're trying to convert a whole list into an integer, you are going to have to convert the list into a string first:

x = ["0", "1", "2"]
y = ''.join(x) # converting list into string
z = int(y)

If your list elements are not strings, you'll have to convert them to strings before using str.join:

x = [0, 1, 2]
y = ''.join(map(str, x))
z = int(y)

Also, as stated above, make sure that you're not returning a nested list.

import form module in app.module.ts.

import { FormsModule} from '@angular/forms';


@NgModule({
  declarations: [
    AppComponent,
    ContactsComponent
  ],
  imports: [
    BrowserModule,HttpModule,FormsModule     //Add here form  module
  ],
  providers: [],
  bootstrap: [AppComponent]
})

In html:

<input type="text" name="last_name" [(ngModel)]="last_name" [ngModelOptions]="{standalone: true}" class="form-control">

You are mixing the 2 different CASE syntaxes inappropriately.

Use this style (Searched)

  CASE  
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Or this style (Simple)

  CASE u.nnmu 
  WHEN '0' THEN mu.naziv_mesta
  WHEN '1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Not This (Simple but with boolean search predicates)

  CASE u.nnmu 
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

In MySQL this will end up testing whether u.nnmu is equal to the value of the boolean expression u.nnmu ='0' itself. Regardless of whether u.nnmu is 1 or 0 the result of the case expression itself will be 1

For example if nmu = '0' then (nnmu ='0') evaluates as true (1) and (nnmu ='1') evaluates as false (0). Substituting these into the case expression gives

 SELECT CASE  '0'
  WHEN 1 THEN '0'
  WHEN 0 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

if nmu = '1' then (nnmu ='0') evaluates as false (0) and (nnmu ='1') evaluates as true (1). Substituting these into the case expression gives

 SELECT CASE  '1'
  WHEN 0 THEN '0'
  WHEN 1 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

None is used to indicate "not set", whereas any other value is used to indicate a "default" value.

Hence, if your class copes with empty strings and you like it as a default value, use "". If your class needs to check if the variable was set at all, use None.

Notice that it doesn't matter if your variable is a string initially. You can change it to any other type/value at any other moment.

Had the same issue. Check with sublime.log_input(True) command on the console to see what keys are being detected with the CTRL+/ and SHIFT+CTRL+/ shorcuts. Then replace the shortcuts with those. (Changing / for keypad_divide worked for me)

One thing to note when using uuid1, if you use the default call (without giving clock_seq parameter) you have a chance of running into collisions: you have only 14 bit of randomness (generating 18 entries within 100ns gives you roughly 1% chance of a collision see birthday paradox/attack). The problem will never occur in most use cases, but on a virtual machine with poor clock resolution it will bite you.

This should work:

System.currentTimeMillis();

Checking for existence of an element is documented neatly in the official jQuery website itself!

Use the .length property of the jQuery collection returned by your selector:

if ($("#myDiv").length) {
    $("#myDiv").show();
}

Note that it isn't always necessary to test whether an element exists. The following code will show the element if it exists, and do nothing (with no errors) if it does not:

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

clearfix should contain the floating elements but in your html you have added clearfix only after floating right that is your pull-right so you should do like this:

<div class="clearfix">
  <div id="sidebar">
    <ul>
      <li>A</li>
      <li>A</li>
      <li>C</li>
      <li>D</li>
      <li>E</li>
      <li>F</li>
      <li>...</li>
      <li>Z</li>
    </ul>
  </div>
  <div id="main">
    <div>
      <div class="pull-right">
        <a>RIGHT</a>
      </div>
    </div>
  <div>MOVED BELOW Z</div>
</div>

see this demo

Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden; as you have done in your main.

For debug/release flags, see the CMAKE_BUILD_TYPE variable (you pass it as cmake -DCMAKE_BUILD_TYPE=value). It takes values like Release, Debug, etc.

https://gitlab.kitware.com/cmake/community/wikis/doc/cmake/Useful-Variables#compilers-and-tools

cmake uses the extension to choose the compiler, so just name your files .c.

You can override this with various settings:

For example:

set_source_files_properties(yourfile.c LANGUAGE CXX) 

Would compile .c files with g++. The link above also shows how to select a specific compiler for C/C++.

You can also work with a so called boolean vector, aka logical:

row_to_keep = c(TRUE, FALSE, TRUE, FALSE, TRUE, FALSE, TRUE)
myData = myData[row_to_keep,]

Note that the ! operator acts as a NOT, i.e. !TRUE == FALSE:

myData = myData[!row_to_keep,]

This seems a bit cumbersome in comparison to @mrwab's answer (+1 btw :)), but a logical vector can be generated on the fly, e.g. where a column value exceeds a certain value:

myData = myData[myData$A > 4,]
myData = myData[!myData$A > 4,] # equal to myData[myData$A <= 4,]

You can transform a boolean vector to a vector of indices:

row_to_keep = which(myData$A > 4)

Finally, a very neat trick is that you can use this kind of subsetting not only for extraction, but also for assignment:

myData$A[myData$A > 4,] <- NA

where column A is assigned NA (not a number) where A exceeds 4.

window.location.href = 'URL';

is the standard implementation for changing the current window's location.

The documentation for this is good if not a little difficult to find.

Facebook Graph API - Page Tokens

After initializing node's fbgraph, you can run:

var facebookAccountID = yourAccountIdHere 

graph
.setOptions(options)
.get(facebookAccountId + "/accounts", function(err, res) {
  console.log(res); 
});

and receive a JSON response with the token you want to grab, located at:

res.data[0].access_token

In the most shared hosts you can't set it.

On a VPS or dedicated server, you can set it, but everything has its price.

On shared hosts, in general you receive a Linux account, something such as /home/(your username)/, and the equivalent of /var/www/html turns to /home/(your username)/public_html/ (or something similar, such as /home/(your username)/www)

If you're accessing your account via FTP, you automatically has accessing the your */home/(your username)/ folder, just find the www or public_html and put your site in it.

If you're using absolute path in the code, bad news, you need to refactor it to use relative paths in the code, at least in a shared host.

Depending on the number of endpoints you need it may be easier to do it manually.

I have tried 10 libraries "soap nodejs" I finally do it manually.

• use node request (https://github.com/mikeal/request) to form input xml message to send (POST) the request to the web service
• use xml2j ( https://github.com/Leonidas-from-XIV/node-xml2js ) to parse the reponse

Request takes a callback method, its async! So I am assuming, by the time the callback is executed the res.end() might get called. Try closing the request within the callback.

Find programs who used app/build/outputs/apk folder, then just delete folder.

I think Android Studio have to delete old apk folder before rebuilding.

JSON files don’t require an explicit exports statement. You don't need to export to use it as Javascript files.

So, you can use just require for valid JSON document.

data.json

{
  "name": "Freddie Mercury"
}

main.js

var obj = require('data.json');

console.log(obj.name); 
//Freddie Mercury

It's not a good way.

When doing conversion from int to string, this should be used:

int i = 5;
String strI = String.valueOf(i);

studying the above answers almost worked for me ... but I still had a problem that I could 'fling' the view on 2.1 (seemed to be fixed with 2.2 & 2.3).

here is my final solution

public class MyWebView extends WebView
{
private boolean bAllowScroll = true;

Try using Joda Time instead of standard java.util.Date classes. Joda Time library has much better API for handling dates.

DateTime dt = new DateTime();  // current time
int month = dt.getMonth();     // gets the current month
int hours = dt.getHourOfDay(); // gets hour of day

See this question for pros and cons of using Joda Time library.

Joda Time may also be included to some future version of Java as a standard component, see JSR-310.

If you must use traditional java.util.Date and java.util.Calendar classes, see their JavaDoc's for help (java.util.Calendar and java.util.Date).

You can use the traditional classes like this to fetch fields from given Date instance.

Date date = new Date();   // given date
Calendar calendar = GregorianCalendar.getInstance(); // creates a new calendar instance
calendar.setTime(date);   // assigns calendar to given date 
calendar.get(Calendar.HOUR_OF_DAY); // gets hour in 24h format
calendar.get(Calendar.HOUR);        // gets hour in 12h format
calendar.get(Calendar.MONTH);       // gets month number, NOTE this is zero based!
