It is mentioned in the .data() documentation

The data- attributes are pulled in the first time the data property is accessed and then are no longer accessed or mutated (all data values are then stored internally in jQuery)

This was also covered on Why don't changes to jQuery $.fn.data() update the corresponding html 5 data-* attributes?

The demo on my original answer below doesn't seem to work any more.

Updated answer

Again, from the .data() documentation

The treatment of attributes with embedded dashes was changed in jQuery 1.6 to conform to the W3C HTML5 specification.

So for <div data-role="page"></div> the following is true $('div').data('role') === 'page'

I'm fairly sure that $('div').data('data-role') worked in the past but that doesn't seem to be the case any more. I've created a better showcase which logs to HTML rather than having to open up the Console and added an additional example of the multi-hyphen to camelCase data- attributes conversion.

Updated demo (2015-07-25)

$('#changeData').click();

Older demo

Original answer

For this HTML:

<div id="foo" data-helptext="bar"></div>
<a href="#" id="changeData">change data value</a>

and this JavaScript (with jQuery 1.6.2)

console.log($('#foo').data('helptext'));

$('#changeData').click(function() {
    $('#foo').data('helptext', 'Testing 123');
//  $('#foo').attr('data-helptext', 'Testing 123');
    console.log($('#foo').data('data-helptext'));
    return false;
});

See demo

Using the Chrome DevTools Console to inspect the DOM, the $('#foo').data('helptext', 'Testing 123'); does not update the value as seen in the Console but $('#foo').attr('data-helptext', 'Testing 123'); does.

You can simplify this code to:

        DirectorySearcher searcher = new DirectorySearcher();
        searcher.Filter = "(&(objectCategory=user)(cn=steve.evans))";

        SearchResultCollection results = searcher.FindAll();

        if (results.Count == 1)
        {
            //do what you want to do
        }
        else if (results.Count == 0)
        {
            //user does not exist
        }
        else
        {
            //found more than one user
            //something is wrong
        }

If you can narrow down where the user is you can set searcher.SearchRoot to a specific OU that you know the user is under.

You should also use objectCategory instead of objectClass since objectCategory is indexed by default.

You should also consider searching on an attribute other than CN. For example it might make more sense to search on the username (sAMAccountName) since it's guaranteed to be unique.

You can try like this:

private String getCharForNumber(int i) {
    CharSequence css = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    if (i > 25) {
        return null;
    }
    return css.charAt(i) + "";
}

You didn't bind all your bindings here

$sql = "SELECT SQL_CALC_FOUND_ROWS *, UNIX_TIMESTAMP(publicationDate) AS publicationDate     FROM comments WHERE articleid = :art 
ORDER BY " . mysqli_escape_string($order) . " LIMIT :numRows";

$st = $conn->prepare( $sql );
$st->bindValue( ":art", $art, PDO::PARAM_INT );

You've declared a binding called :numRows but you never actually bind anything to it.

UPDATE 2019: I keep getting upvotes on this and that reminded me of another suggestion

Double quotes are string interpolation in PHP, so if you're going to use variables in a double quotes string, it's pointless to use the concat operator. On the flip side, single quotes are not string interpolation, so if you've only got like one variable at the end of a string it can make sense, or just use it for the whole string.

In fact, there's a micro op available here since the interpreter doesn't care about parsing the string for variables. The boost is nearly unnoticable and totally ignorable on a small scale. However, in a very large application, especially good old legacy monoliths, there can be a noticeable performance increase if strings are used like this. (and IMO, it's easier to read anyway)

try this

$(function(){
  $("textarea[maxlength]")
    .keydown(function(event){
       return !$(this).attr("maxlength") || this.value.length < $(this).attr("maxlength") || event.keyCode == 8 || event.keyCode == 46;
    })
    .keyup(function(event){
      var limit = $(this).attr("maxlength");

      if (!limit) return;

      if (this.value.length <= limit) return true;
      else {
        this.value = this.value.substr(0,limit);
        return false;
      }    
    });
});

For me works really perfect without jumping/showing additional characters; works exactly like maxlength on input

You can set a very small initial delay-time (e.g. 100) and set it to your desired delay-time within the function:

var delay = 100;_x000D_
_x000D_
function foo() {_x000D_
  console.log("Change initial delay-time to what you want.");_x000D_
  delay = 12000;_x000D_
  setTimeout(foo, delay);_x000D_
}

For an example of how Action<> is used.

Console.WriteLine has a signature that satisifies Action<string>.

    static void Main(string[] args)
    {
        string[] words = "This is as easy as it looks".Split(' ');

        // Passing WriteLine as the action
        Array.ForEach(words, Console.WriteLine);         
    }

Hope this helps

You can create an unsigned char:

unsigned char c = 0xc5;

Printing it will give C5 and not ffffffc5.

Only the chars bigger than 127 are printed with the ffffff because they are negative (char is signed).

Or you can cast the char while printing:

char c = 0xc5; 
printf("%x", (unsigned char)c);

All i'm going to say in this answer is make sure you uh... don't have anything similar to this in your service registration code..

        while (!Debugger.IsAttached) {
            Thread.Sleep(500);
        }

This totally did not happen to me and definitely did not make me a very sad boy after 3 hours of screwing around with all of the above answers and more.

If you have installed angular cli globally but ng isn't working, just do this:

echo -e "export PATH=$(npm prefix -g)/bin:$PATH" >> ~/.bashrc

source ~/.bashrc

ng --version

I solved this problem with following piece of code in command line way:

File outputFile = new File("pathToFile"); 
Runtime.getRuntime().exec("logcat -c");
Runtime.getRuntime().exec("logcat -v time -f " + outputFile.getAbsolutePath())

Where "time" option adds metadata field details for date, invocation time, priority/tag, and PID of the process issuing the message.

Then in your code just do something similar to this (using android.util.Log):

Log.d("yourappname", "Your message");

If you need some es6 improvements not supported by Typescript, you can target es6 in your tsconfig and use Babel to convert your files in es5.

To find the sessions, as a DBA use

select sid,serial# from v$session where username = '<your_schema>'

If you want to be sure only to get the sessions that use SQL Developer, you can add and program = 'SQL Developer'. If you only want to kill sessions belonging to a specific developer, you can add a restriction on os_user

Then kill them with

alter system kill session '<sid>,<serial#>'

(e.g. alter system kill session '39,1232')

A query that produces ready-built kill-statements could be

select 'alter system kill session ''' || sid || ',' || serial# || ''';' from v$session where username = '<your_schema>'

This will return one kill statement per session for that user - something like:

alter system kill session '375,64855';

alter system kill session '346,53146';

Another possible solution is to compare current date with January 1, 1970, you can get January 1, 1970 by new Date(0);

var date = new Date(); 
var myDate= date - new Date(0);

You can use lodash sortBy (https://lodash.com/docs/4.17.4#sortBy).

Your code could be like:

const myArray = [  
   {  
      "id":25,
      "name":"Anakin Skywalker",
      "createdAt":"2017-04-12T12:48:55.000Z",
      "updatedAt":"2017-04-12T12:48:55.000Z"
   },
   {  
      "id":1,
      "name":"Luke Skywalker",
      "createdAt":"2017-04-12T11:25:03.000Z",
      "updatedAt":"2017-04-12T11:25:03.000Z"
   }
]

const myOrderedArray = _.sortBy(myArray, o => o.name)

The problem is that a cast is a runtime check - but due to type erasure, at runtime there's actually no difference between a HashMap<String,String> and HashMap<Foo,Bar> for any other Foo and Bar.

Use @SuppressWarnings("unchecked") and hold your nose. Oh, and campaign for reified generics in Java :)

Put this formula in cell d31 and copy down to d39

 =iferror(vlookup(b31,$f$3:$g$12,2,0),"")

Here's what is going on. VLOOKUP:

• Takes a value (here the contents of b31),
• Looks for it in the first column of a range (f3:f12 in the range f3:g12), and
• Returns the value for the corresponding row in a column in that range (in this case, the 2nd column or g3:g12 of the range f3:g12).

As you know, the last argument of VLOOKUP sets the match type, with FALSE or 0 indicating an exact match.

Finally, IFERROR handles the #N/A when VLOOKUP does not find a match.

I was just going through this myself. I had ensured that my MSSQLSERVER login user had full access but it was still causing issues. It only worked once I moved the destination to the root of C. More importantly out of a user folder (even though I had a share with full permissions - even tried "Everyone" as a test).

I don't know if i consider my issue "fixed", however it is "working".

Just a FYI for any other users that come across this thread.

Try by giving Grant permission Command of mysql

try this:

::Example directory
set SetupDir=C:\Users

::Loop in the folder with "/r" to search in recursive folders, %%f being a loop ::variable 
for /r "%SetupDir%" %%f in (*.msi *.exe) do set /a counter+=1

echo there are %counter% files in your folder

it counts .msi and .exe files in your directory (and in the sub directory). So it also makes the difference between folders and files as executables.

Just add an extension (.pptx .docx ..) if you need to filter other files in the loop

The default behavior of google drive is to scan files for viruses if the file is to big it will prompte the user and notifies him that the file could not be scanned.

At the moment the only workaround I found is to share the file with the web and create a web resource.

Quote from the google drive help page:

With Drive, you can make web resources — like HTML, CSS, and Javascript files — viewable as a website.

To host a webpage with Drive:

1. Open Drive at drive.google.com and select a file.
2. Click the Share button at the top of the page.
3. Click Advanced in the bottom right corner of the sharing box.
4. Click Change....
5. Choose On - Public on the web and click Save.
6. Before closing the sharing box, copy the document ID from the URL in the field below "Link to share". The document ID is a string of uppercase and lowercase letters and numbers between slashes in the URL.
7. Share the URL that looks like "www.googledrive.com/host/[doc id] where [doc id] is replaced by the document ID you copied in step 6.
   Anyone can now view your webpage.

Found here: https://support.google.com/drive/answer/2881970?hl=en

So for example when you share a file on google drive publicly the sharelink looks like this:

https://drive.google.com/file/d/0B5IRsLTwEO6CVXFURmpQZ1Jxc0U/view?usp=sharing

Then you copy the file id and create a googledrive.com linke that look like this:

https://www.googledrive.com/host/0B5IRsLTwEO6CVXFURmpQZ1Jxc0U

Just tell request that you are using json:true and forget about header and parse

var options = {
    hostname: '127.0.0.1',
    port: app.get('port'),
    path: '/users',
    method: 'GET',
    json:true
}
request(options, function(error, response, body){
    if(error) console.log(error);
    else console.log(body);
});

and the same for post

var options = {
    hostname: '127.0.0.1',
    port: app.get('port'),
    path: '/users',
    method: 'POST',
    json: {"name":"John", "lastname":"Doe"}
}
request(options, function(error, response, body){
    if(error) console.log(error);
    else console.log(body);
});

For apache-tomcat-8.5.28

modify JDPA_OPTS like the below then run like catalina.bat jpda start

JPDA_OPTS="-agentlib:jdwp=transport=$JPDA_TRANSPORT,address=$JPDA_ADDRESS,server=y,suspend=$JPDA_SUSPEND"
JPDA_OPTS="-agentlib:jdwp=transport=$JPDA_TRANSPORT,address=8000,server=y,suspend=$JPDA_SUSPEND"

Anytime you have a question about a particular function in PHP, the easiest way to get quick answers is by visiting php.net, which has great documentation on all of the language's capabilities.

Looking up a function is easy, just visit http://php.net/<function name> and it will forward you to the appropriate place. For the date function, we'll visit http://php.net/date.

We immediately learn a couple things about this function by examining its signature:

string date ( string $format [, int $timestamp = time() ] )

First, it returns a string. That's what the first string in the above code means. Secondly, the first parameter is expected to be a string containing the format. There is an optional second parameter for passing in your own timestamp (to construct strings from some time other than now).

date("d-m-Y") // produces something like 03-12-2012

In this code, d represents the day of the month (with a leading 0 is necessary). m represents the month, again with a leading zero if necessary. And Y represents the full 4-digit year. All of these are documented in the aforementioned link.

To satisfy your request of getting the hours, minutes, and seconds, we need to give a quick look at the documentation to see which characters represents those particular units of time. When we do that, we find the following:

h   12-hour format of an hour with leading zeros    01 through 12
i   Minutes with leading zeros                      00 to 59
s   Seconds, with leading zeros                     00 through 59

With this in mind, we can no create a new format string:

date("d-m-Y h:i:s"); // produces something like 03-12-2012 03:29:13

Hope this is helpful, and I hope you find the documentation has benefiting to your development as I have to mine.

You can actually do this one of two ways:

MySQL update join syntax:

UPDATE tableA a
INNER JOIN tableB b ON a.name_a = b.name_b
SET validation_check = if(start_dts > end_dts, 'VALID', '')
-- where clause can go here

ANSI SQL syntax:

UPDATE tableA SET validation_check = 
    (SELECT if(start_DTS > end_DTS, 'VALID', '') AS validation_check
        FROM tableA
        INNER JOIN tableB ON name_A = name_B
        WHERE id_A = tableA.id_A)

Pick whichever one seems most natural to you.

Your code snippet,

if number >= 10000 and number >= 30000:
    print ("you have to pay 5% taxes")

actually checks if number is larger than both 10000 and 30000.

Assuming you want to check that the number is in the range 10000 - 30000, you could use the Python interval comparison:

if 10000 <= number <= 30000:
    print ("you have to pay 5% taxes")

This Python feature is further described in the Python documentation.

[Edit]

As noted in comments above, while still on some UA implementations, readAsBinaryString method didn't made its way to the specs and should not be used in production. Instead, use readAsArrayBuffer and loop through it's buffer to get back the binary string :

document.querySelector('input').addEventListener('change', function() {_x000D_
_x000D_
  var reader = new FileReader();_x000D_
  reader.onload = function() {_x000D_
_x000D_
    var arrayBuffer = this.result,_x000D_
      array = new Uint8Array(arrayBuffer),_x000D_
      binaryString = String.fromCharCode.apply(null, array);_x000D_
_x000D_
    console.log(binaryString);_x000D_
_x000D_
  }_x000D_
  reader.readAsArrayBuffer(this.files[0]);_x000D_
_x000D_
}, false);

<input type="file" />_x000D_
<div id="result"></div>

For a more robust way to convert your arrayBuffer in binary string, you can refer to this answer.

[old answer] _(modified)

Yes, the file API does provide a way to convert your File, in the <input type="file"/> to a binary string, thanks to the FileReader Object and its method readAsBinaryString.
[But don't use it in production !]

document.querySelector('input').addEventListener('change', function(){_x000D_
    var reader = new FileReader();_x000D_
    reader.onload = function(){_x000D_
        var binaryString = this.result;_x000D_
        document.querySelector('#result').innerHTML = binaryString;_x000D_
        }_x000D_
    reader.readAsBinaryString(this.files[0]);_x000D_
  }, false);

<input type="file"/>_x000D_
<div id="result"></div>

If you want an array buffer, then you can use the readAsArrayBuffer() method :

document.querySelector('input').addEventListener('change', function(){_x000D_
    var reader = new FileReader();_x000D_
    reader.onload = function(){_x000D_
        var arrayBuffer = this.result;_x000D_
      console.log(arrayBuffer);_x000D_
        document.querySelector('#result').innerHTML = arrayBuffer + '  '+arrayBuffer.byteLength;_x000D_
        }_x000D_
    reader.readAsArrayBuffer(this.files[0]);_x000D_
  }, false);

<input type="file"/>_x000D_
<div id="result"></div>

Subquery is the name.

At times it's required, but good/bad depends on how it's applied.

It somewhat depends on what you use as a CGI framework, but they are available in dictionaries accessible to the program. I'd point you to the docs, but I'm not getting through to python.org right now. But this note on mail.python.org will give you a first pointer. Look at the CGI and URLLIB Python libs for more.

Update

Okay, that link busted. Here's the basic wsgi ref

select regexp_replace(field, E'[\\n\\r\\u2028]+', ' ', 'g' )

I had the same problem in my postgres d/b, but the newline in question wasn't the traditional ascii CRLF, it was a unicode line separator, character U2028. The above code snippet will capture that unicode variation as well.

Update... although I've only ever encountered the aforementioned characters "in the wild", to follow lmichelbacher's advice to translate even more unicode newline-like characters, use this:

select regexp_replace(field, E'[\\n\\r\\f\\u000B\\u0085\\u2028\\u2029]+', ' ', 'g' )

1. Your UPDATE syntax is wrong
2. You probably meant to update a row not all of them so you have to use WHERE clause to target your specific row

Change

UPDATE `access_users`   
      (`contact_first_name`,`contact_surname`,`contact_email`,`telephone`) 
      VALUES (:firstname, :surname, :telephone, :email)

to

UPDATE `access_users`   
   SET `contact_first_name` = :firstname,
       `contact_surname` = :surname,
       `contact_email` = :email,
       `telephone` = :telephone 
 WHERE `user_id` = :user_id -- you probably have some sort of id 

Enable "resolveJsonModule": true in tsconfig.json file and implement as below code, it's work for me:

@Autowired annotation is defined in the Spring framework.

@Inject annotation is a standard annotation, which is defined in the standard "Dependency Injection for Java" (JSR-330). Spring (since the version 3.0) supports the generalized model of dependency injection which is defined in the standard JSR-330. (Google Guice frameworks and Picocontainer framework also support this model).

With @Inject can be injected the reference to the implementation of the Provider interface, which allows injecting the deferred references.

Annotations @Inject and @Autowired- is almost complete analogies. As well as @Autowired annotation, @Inject annotation can be used for automatic binding properties, methods, and constructors.

In contrast to @Autowired annotation, @Inject annotation has no required attribute. Therefore, if the dependencies will not be found - will be thrown an exception.

There are also differences in the clarifications of the binding properties. If there is ambiguity in the choice of components for the injection the @Named qualifier should be added. In a similar situation for @Autowired annotation will be added @Qualifier qualifier (JSR-330 defines it's own @Qualifier annotation and via this qualifier annotation @Named is defined).

It happens on different versions of ff. I'm using latest ff version 39 by using selenium-server-standalone-2.41.0.jar and selenium-java-2.41.0.zip which shows same error.

Get the latest server and client jar files here for the compatibility i used server and client versions 2.47.0 and 2.47.1 respectively. And Boom! It worked.

I've always used .place() for my tkinter widgets. place syntax

You can specify the size of it just by changing the keyword arguments!

Of course, you will have to call .place() again if you want to change it.

Works in python 3.8.2, if you're wondering.

The answers in question you linked-to are all about configuring git so that you can enter very short git push commands and have them do whatever you want. Which is great, if you know what you want and how to spell that in Git-Ese, but you're new to git! :-)

In your case, Petr Mensik's answer is the (well, "a") right one. Here's why:

The command git push remote roots around in your .git/config file to find the named "remote" (e.g., origin). The config file lists:

• where (URL-wise) that remote "lives" (e.g., ssh://hostname/path)
• where pushes go, if different
• what gets pushed, if you didn't say what branch(es) to push
• what gets fetched when you run git fetch remote

When you first cloned the repo—whenever that was—git set up default values for some of these. The URL is whatever you cloned from and the rest, if set or unset, are all "reasonable" defaults ... or, hmm, are they?

The issue with these is that people have changed their minds, over time, as to what is "reasonable". So now (depending on your version of git and whether you've configured things in detail), git may print a lot of warnings about defaults changing in the future. Adding the name of the "branch to push"—amd_qlp_tester—(1) shuts it up, and (2) pushes just that one branch.

If you want to push more conveniently, you could do that with:

git push origin

or even:

git push

but whether that does what you want, depends on whether you agree with "early git authors" that the original defaults are reasonable, or "later git authors" that the original defaults aren't reasonable. So, when you want to do all the configuration stuff (eventually), see the question (and answers) you linked-to.

As for the name origin/amd_qlp_tester in the first place: that's actually a local entity (a name kept inside your repo), even though it's called a "remote branch". It's git's best guess at "where amd_qlp_tester is over there". Git updates it when it can.

You can do this:

<div class"my_class">
<?php if ($cart->count_product > 0) {
          print $cart->count_product; 
      } else { 
          print ''; 
      } 
?>
</div>

Before hitting the div, we are not in PHP tags

In your example, you can replace the forEach with lamdba with a simple for loop and modify any variable freely. Or, probably, refactor your code so that you don't need to modify any variables. However, I'll explain for completeness what does the error mean and how to work around it.

Java 8 Language Specification, §15.27.2:

Any local variable, formal parameter, or exception parameter used but not declared in a lambda expression must either be declared final or be effectively final (§4.12.4), or a compile-time error occurs where the use is attempted.

Basically you cannot modify a local variable (calTz in this case) from within a lambda (or a local/anonymous class). To achieve that in Java, you have to use a mutable object and modify it (via a final variable) from the lambda. One example of a mutable object here would be an array of one element:

private TimeZone extractCalendarTimeZoneComponent(Calendar cal, TimeZone calTz) {
    TimeZone[] result = { null };
    try {
        cal.getComponents().getComponents("VTIMEZONE").forEach(component -> {
            ...
            result[0] = ...;
            ...
        }
    } catch (Exception e) {
        log.warn("Unable to determine ical timezone", e);
    }
    return result[0];
}

You can’t run arbitrary Python code in jinja; it doesn’t work like JSP in that regard (it just looks similar). All the things in jinja are custom syntax.

For your purpose, it would make most sense to define a custom filter, so you could for example do the following:

The grass is {{ variable1 | splitpart(0, ',') }} and the boat is {{  splitpart(1, ',') }}
Or just:
The grass is {{ variable1 | splitpart(0) }} and the boat is {{  splitpart(1) }}

The filter function could then look like this:

def splitpart (value, index, char = ','):
    return value.split(char)[index]

An alternative, which might make even more sense, would be to split it in the controller and pass the splitted list to the view.

Here is a PHP solution ready for use with a n:m (many-to-many relationship) table :

// get data
$table_1 = get_table_1_rows();
$table_2_fk_id = 123;

// prepare first part of the query (before values)
$query = "INSERT INTO `table` (
   `table_1_fk_id`,
   `table_2_fk_id`,
   `insert_date`
) VALUES ";

//loop the table 1 to get all foreign keys and put it in array
foreach($table_1 as $row) {
    $query_values[] = "(".$row["table_1_pk_id"].", $table_2_fk_id, NOW())";
}

// Implode the query values array with a coma and execute the query.
$db->query($query . implode(',',$query_values));

Change it to:

<div style="background-color:black; overflow:hidden;" onmouseover="this.bgColor='white'">
<div style="float:left">hello</div>
<div style="float:right">world</div>
</div>

Basically the outer div only contains floats. Floats are removed from the normal flow. As such the outer div really contains nothing and thus has no height. It really is black but you just can't see it.

The overflow:hidden property basically makes the outer div enclose the floats. The other way to do this is:

<div style="background-color:black" onmouseover="this.bgColor='white'">
<div style="float:left">hello</div>
<div style="float:right">world</div>
<div style="clear:both></div>
</div>

Oh and just for completeness, you should really prefer classes to direct CSS styles.

Yes but it is not quite that easy. Create a third array that is the size of the two arrays combined and loop through each original array and move the items over. Also look into System.arraycopy().

From the documentation (MySQL 8) :

      Type | Maximum length
-----------+-------------------------------------
  TINYTEXT |           255 (2 8−1) bytes
      TEXT |        65,535 (216−1) bytes = 64 KiB
MEDIUMTEXT |    16,777,215 (224−1) bytes = 16 MiB
  LONGTEXT | 4,294,967,295 (232−1) bytes =  4 GiB

Note that the number of characters that can be stored in your column will depend on the character encoding.

You are passing wrong mode to you view. Your view is looking for @model IEnumerable<Standings.Models.Teams> and you are passing var model = tm.Name.ToList(); name list. You have to pass list of Teams.

You have to pass following model

var model = new List<Teams>();

model.Add(new Teams { Name =  new List<string>(){"Sky","ABC"}});
model.Add(new Teams { Name =  new List<string>(){"John","XYZ"} });
return View(model);

1. Typically in a dotfile (like .myprogramrc) in the user's home directory.
2. It is of course up to the programmer but normally command line arguments override everything else. If environment variables are used it is usually as an alternative to the command line arguments or to specify where the configuration is located.

Resolved it in 2 minutes downtime :)
Just move your folder, add symlink, then tune permissions.

sudo service mongod stop
sudo mv mongodb /new/disk/mongodb/
sudo ln -s /new/disk/mongodb/ /var/lib/mongodb
sudo chown mongodb:mongodb /new/disk/mongodb/
sudo service mongod start

# test if mongodb user can access new location:
sudo -u mongodb -s cd /new/disk/mongodb/
# resolve other permissions issues if necessary
sudo usermod -a -G <newdisk_grp> mongodb

Add an input id to the element and do something like that:

document.getElementById('inputId').value.split(/[\\$]/).pop()

new_vector.assign(old_vector.begin(),old_vector.end()); // Method 1
new_vector = old_vector; // Method 2

In Python you generally have for in loops instead of general for loops like C/C++, but you can achieve the same thing with the following code.

for k in range(1, c+1, 2):
  do something with k

Reference Loop in Python.

It may be possible (but very hackish) with only CSS using the :before or :after pseudo elements:

.bgtext {_x000D_
  position: relative;_x000D_
}_x000D_
_x000D_
.bgtext:after {_x000D_
  content: "Background text";_x000D_
  position: absolute;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
  z-index: -1;_x000D_
}

<div class="bgtext">_x000D_
  Foreground text_x000D_
</div>

This seems to work, but you'll probably need to tweak it a little. Also note it won't work in IE6 because it doesn't support :after.

After trying all the above and using the answer from @Aaron Hall, I was getting memory errors for a ~90 Mb file on a computer running Window 10, 8 Gb RAM and Python 3.5 32-bit. I was recommended by a colleague to use numpy instead and it works wonders.

By far, the fastest to read an entire binary file (that I have tested) is:

import numpy as np

file = "binary_file.bin"
data = np.fromfile(file, 'u1')

Reference

Multitudes faster than any other methods so far. Hope it helps someone!

Incase someone is still trying to figure this out. This is how you get the center X and Y of the view.

    int pos[] = new int[2];
    view.getLocationOnScreen(pos);
    int centerX = pos[0] + view.getMeasuredWidth() / 2;
    int centerY = pos[1] + view.getMeasuredHeight() / 2;

a minimal bash loop you can build off of (based off ghostdog74 answer)

for dir in directory/*                                                     
do                                                                                 
  echo ${dir}                                                                  
done

to zip a whole bunch of files by directory

for dir in directory/*
do
  zip -r ${dir##*/} ${dir}
done                                               

If it helps anybody, for me that happened because I was trying to run a Django implementation in python 3.4 with my python 2.7 command

function shuffle(maxElements) {
    //create ordered array : 0,1,2,3..maxElements
    for (var temArr = [], i = 0; i < maxElements; i++) {
        temArr[i] = i;
    }

    for (var finalArr = [maxElements], i = 0; i < maxElements; i++) {
        //remove rundom element form the temArr and push it into finalArrr
        finalArr[i] = temArr.splice(Math.floor(Math.random() * (maxElements - i)), 1)[0];
    }

    return finalArr
}

I guess this method will solve the issue with the probabilities, only limited by random numbers generator.

If you're using rails you can also use in_groups_of:

foo.in_groups_of(3)

Another alternative approach is:

How do I create a Java string from the contents of a file?

Other option is to use utilities provided open source libraries
http://commons.apache.org/io/api-1.4/index.html?org/apache/commons/io/IOUtils.html

Why java doesn't provide such a common util API ?
a) to keep the APIs generic so that encoding, buffering etc is handled by the programmer.
b) make programmers do some work and write/share opensource util libraries :D ;-)

The solution for Bootstrap 4, it works perfect in all of my projects:

change your first line from

navbar-fixed-top

to

sticky-top

Bootstrap documentation reference

About time they did this right :D

This worked for me in Angular 2:

var img = new Image()
img.src = 'assets/sample.png'
pdf.addImage(img, 'png', 10, 78, 12, 15)

jsPDF version 1.5.3

assets directory is in src directory of the Angular project root

DateTime is not a function, but the class.

When you just reference a class like new DateTime() PHP searches for the class in your current namespace. However the DateTime class obviously doesn't exists in your controllers namespace but rather in root namespace.

You can either reference it in the root namespace by prepending a backslash:

$now = new \DateTime();

Or add an import statement at the top:

use DateTime;

$now = new DateTime();

I"m using an extension method for pre C# 6 projects and the nameof() for those targeting C# 6.

public static class MiscExtentions
{
    public static string NameOf<TModel, TProperty>(this object @object, Expression<Func<TModel, TProperty>> propertyExpression)
    {
        var expression = propertyExpression.Body as MemberExpression;
        if (expression == null)
        {
            throw new ArgumentException("Expression is not a property.");
        }

        return expression.Member.Name;
    }
}

And i call it like:

public class MyClass 
{
    public int Property1 { get; set; }
    public string Property2 { get; set; }
    public int[] Property3 { get; set; }
    public Subclass Property4 { get; set; }
    public Subclass[] Property5 { get; set; }
}

public class Subclass
{
    public int PropertyA { get; set; }
    public string PropertyB { get; set; }
}

// result is Property1
this.NameOf((MyClass o) => o.Property1);
// result is Property2
this.NameOf((MyClass o) => o.Property2);
// result is Property3
this.NameOf((MyClass o) => o.Property3);
// result is Property4
this.NameOf((MyClass o) => o.Property4);
// result is PropertyB
this.NameOf((MyClass o) => o.Property4.PropertyB);
// result is Property5
this.NameOf((MyClass o) => o.Property5);

It works fine with both fields and properties.

Had the same issue. I used a dirty trick like so:

var s = '<div id="myDiv"></div>';
var temp = document.createElement('div');
temp.innerHTML = s;
var htmlObject = temp.firstChild;

Now, you can add styles the way you like:

htmlObject.style.marginTop = something;

In the .css try

.jumbotron {_x000D_
    background-color:red !important; _x000D_
}

They're equivalent. The access is the same.

The import is just a convention to save you from having to type the fully-resolved class name each time. You can write all your Java without using import, as long as you're a fast touch typer.

But there's no difference in efficiency or class loading.

There's a fantastic blogpost that covers this here: Comparing Dates and Datetimes in the Django ORM

The best solution posted for Django>1.7,<1.9 is to register a transform:

from django.db import models

class MySQLDatetimeDate(models.Transform):
    """
    This implements a custom SQL lookup when using `__date` with datetimes.
    To enable filtering on datetimes that fall on a given date, import
    this transform and register it with the DateTimeField.
    """
    lookup_name = 'date'

    def as_sql(self, compiler, connection):
        lhs, params = compiler.compile(self.lhs)
        return 'DATE({})'.format(lhs), params

    @property
    def output_field(self):
        return models.DateField()

Then you can use it in your filters like this:

Foo.objects.filter(created_on__date=date)

EDIT

This solution is definitely back end dependent. From the article:

Of course, this implementation relies on your particular flavor of SQL having a DATE() function. MySQL does. So does SQLite. On the other hand, I haven’t worked with PostgreSQL personally, but some googling leads me to believe that it does not have a DATE() function. So an implementation this simple seems like it will necessarily be somewhat backend-dependent.

Try like this:

$file = '/path/to/foo.txt'; // 'images/'.$file (physical path)

if (file_exists($file)) {
    echo "The file $file exists";
} else {
    echo "The file $file does not exist";
}

The -S switch makes sudo read the password from STDIN. This means you can do

echo mypassword | sudo -S command

to pass the password to sudo

However, the suggestions by others that do not involve passing the password as part of a command such as checking if the user is root are probably much better ideas for security reasons

in angular2 2.1.1 I was not able to catch the exception using the (data),(error) pattern, so I implemented it using .catch(...).

It's nice because it can be used with all other Observable chained methods like .retry .map etc.

import {Observable} from 'rxjs/Rx';


  Http
  .put(...)
  .catch(err =>  { 
     notify('UI error handling');
     return Observable.throw(err); // observable needs to be returned or exception raised
  })
  .subscribe(data => ...) // handle success

from documentation:

Returns

(Observable): An observable sequence containing elements from consecutive source sequences until a source sequence terminates successfully.

This is a custom blink effect I created, which uses setInterval and fadeTo

HTML -

<div id="box">Box</div>

JS -

setInterval(function(){blink()}, 1000);


    function blink() {
        $("#box").fadeTo(100, 0.1).fadeTo(200, 1.0);
    }

As simple as it gets.

import re
re.sub('<.*?>', '', string)
"i think mabe 124 + but I don't have a big experience it just how I see it in my eyes fun stuff"

The re.sub function takes a regular expresion and replace all the matches in the string with the second parameter. In this case, we are searching for all tags ('<.*?>') and replacing them with nothing ('').

The ? is used in re for non-greedy searches.

I fixed this problem by changing the first line in Application.mk from

Look into System.Threading.Timer class. I think this is what you're looking for.

The code example on MSDN seems to show this class doing very similar to what you're trying to do (check status after certain time).

The mentioned code example from the MSDN link:

using System;
using System.Threading;

class TimerExample
{
    static void Main()
    {
        // Create an AutoResetEvent to signal the timeout threshold in the
        // timer callback has been reached.
        var autoEvent = new AutoResetEvent(false);
        
        var statusChecker = new StatusChecker(10);

        // Create a timer that invokes CheckStatus after one second, 
        // and every 1/4 second thereafter.
        Console.WriteLine("{0:h:mm:ss.fff} Creating timer.\n", 
                        DateTime.Now);
        var stateTimer = new Timer(statusChecker.CheckStatus, 
                                autoEvent, 1000, 250);

        // When autoEvent signals, change the period to every half second.
        autoEvent.WaitOne();
        stateTimer.Change(0, 500);
        Console.WriteLine("\nChanging period to .5 seconds.\n");

        // When autoEvent signals the second time, dispose of the timer.
        autoEvent.WaitOne();
        stateTimer.Dispose();
        Console.WriteLine("\nDestroying timer.");
    }
}

class StatusChecker
{
    private int invokeCount;
    private int  maxCount;

    public StatusChecker(int count)
    {
        invokeCount  = 0;
        maxCount = count;
    }

    // This method is called by the timer delegate.
    public void CheckStatus(Object stateInfo)
    {
        AutoResetEvent autoEvent = (AutoResetEvent)stateInfo;
        Console.WriteLine("{0} Checking status {1,2}.", 
            DateTime.Now.ToString("h:mm:ss.fff"), 
            (++invokeCount).ToString());

        if(invokeCount == maxCount)
        {
            // Reset the counter and signal the waiting thread.
            invokeCount = 0;
            autoEvent.Set();
        }
    }
}
// The example displays output like the following:
//       11:59:54.202 Creating timer.
//       
//       11:59:55.217 Checking status  1.
//       11:59:55.466 Checking status  2.
//       11:59:55.716 Checking status  3.
//       11:59:55.968 Checking status  4.
//       11:59:56.218 Checking status  5.
//       11:59:56.470 Checking status  6.
//       11:59:56.722 Checking status  7.
//       11:59:56.972 Checking status  8.
//       11:59:57.223 Checking status  9.

//       12:00:00.980 Checking status  8.
//       12:00:01.481 Checking status  9.

I know this question is a bit old but i would suggest to use some cachebraking hash in the url of the javascript. This works perfectly in production as well as during development because you can have both infinite cache times and intant updates when changes occur.

Lets assume you have a javascript file /js/script.min.js, but in the referencing html/php file you do not use the actual path but:

<script src="/js/script.<?php echo md5(filemtime('/js/script.min.js')); ?>.min.js"></script>

So everytime the file is changed, the browser gets a different url, which in turn means it cannot be cached, be it locally or on any proxy inbetween.

To make this work you need nginx to rewrite any request to /js/script.[0-9a-f]{32}.min.js to the original filename. In my case i use the following directive (for css also):

location ~* \.(css|js)$ {
                expires max;
                add_header Pragma public;
                etag off;
                add_header Cache-Control "public";
                add_header Last-Modified "";
                rewrite  "^/(.*)\/(style|script)\.min\.([\d\w]{32})\.(js|css)$" /$1/$2.min.$4 break;
        }

I would guess that the filemtime call does not even require disk access on the server as it should be in linux's file cache. If you have doubts or static html files you can also use a fixed random value (or incremental or content hash) that is updated when your javascript / css preprocessor has finished or let one of your git hooks change it.

In theory you could also use a cachebreaker as a dummy parameter (like /js/script.min.js?cachebreak=0123456789abcfef), but then the file is not cached at least by some proxies because of the "?".

If you're using HTML5 you don't need to go to any great lengths to perform validation. Just use -

<input type="number" step="any" />

The step attribute allows the decimal point to be valid.

Okay so ideal permissions look like this
For ssh directory (You can get this by typing ls -ld ~/.ssh/)
drwx------ 2 oroborus oroborus 4096 Nov 28 12:05 /home/oroborus/.ssh/

d means directory, rwx means the user oroborus has read write and execute permission. Here oroborus is my computer name, you can find yours by echoing $USER. The second oroborus is actually the group. You can read more about what does each field mean here. It is very important to learn this because if you are working on ubuntu/osx or any Linux distro chances are you will encounter it again.

Now to make your permission look like this, you need to type
sudo chmod 700 ~/.ssh

7 in binary is 111 which means read 1 write 1 and execute 1, you can decode 6 by similar logic means only read-write permissions

You have given your user read write and execute permissions. Make sure your file permissions look like this.

total 20
-rw------- 1 oroborus oroborus  418 Nov  8  2014 authorized_keys
-rw------- 1 oroborus oroborus   34 Oct 19 14:25 config
-rw------- 1 oroborus oroborus 1679 Nov 15  2015 id_rsa
-rw------- 1 oroborus oroborus  418 Nov 15  2015 id_rsa.pub
-rw-r--r-- 1 oroborus root      222 Nov 28 12:12 known_hosts

You have given here read-write permission to your user here for all files. You can see this by typing ls -l ~/.ssh/

This issue occurs because ssh is a program is trying to write to a file called known_hosts in its folder. While writing if it knows that it doesn't have sufficient permissions it will not write in that file and hence fail. This is my understanding of the issue, more knowledgeable people can throw more light in this. Hope it helps

As of OpenCV3.2, life just got a bit easier, you can now rotate an image in a single line of code:

cv::rotate(image, image, cv::ROTATE_90_CLOCKWISE);

For the direction you can choose any of the following:

ROTATE_90_CLOCKWISE
ROTATE_180
ROTATE_90_COUNTERCLOCKWISE

I had a lot of problems with the complete load of a image and the EventListener.

Whatever I tried, the results was not reliable.

But then I found the solution. It is technically not a nice one, but now I never had a failed image load.

What I did:

                    document.getElementById(currentImgID).addEventListener("load", loadListener1);
                    document.getElementById(currentImgID).addEventListener("load", loadListener2);

                function loadListener1()
                    {
                    // Load again
                    }

                function loadListener2()
                {
                    var btn = document.getElementById("addForm_WithImage"); btn.disabled = false;
                    alert("Image loaded");
                }

Instead of loading the image one time, I just load it a second time direct after the first time and both run trough the eventhandler.

All my headaches are gone!

By the way: You guys from stackoverflow helped me already more then hundred times. For this a very big Thank you!

Just looking at the message it sounds like one or more of the components that you reference, or one or more of their dependencies is not registered properly.

If you know which component it is you can use regsvr32.exe to register it, just open a command prompt, go to the directory where the component is and type regsvr32 filename.dll (assuming it's a dll), if it works, try to run the code again otherwise come back here with the error.

If you don't know which component it is, try re-installing/repairing the GIS software (I assume you've installed some GIS software that includes the component you're trying to use).

In the case where you simply want to delete a project from the head revision, so that it no longer shows up in your repo when you run svn list file:///path/to/repo/ just run:

svn delete file:///path/to/repo/project 

However, if you need to delete all record of it in the repo, use another method.

As DACW pointed out, there are method-chaining improvements in pandas 0.18.1 that do what you are looking for very nicely.

Rather than using .where, you can pass your function to either the .loc indexer or the Series indexer [] and avoid the call to .dropna:

test = pd.Series({
383:    3.000000,
663:    1.000000,
726:    1.000000,
737:    9.000000,
833:    8.166667
})

test.loc[lambda x : x!=1]

test[lambda x: x!=1]

Similar behavior is supported on the DataFrame and NDFrame classes.

Thanks all for your help! Finally I used JQuery/AJAX as you suggested, passing the parameter using model.

So, in JS:

$('#divPoints').load('/Schedule/UpdatePoints', UpdatePointsAction);
var points= $('#newpoints').val();
$element.find('PointsDiv').html("You have" + points+ " points");

In Controller:

var model = _newPoints;
return PartialView(model);

In View

<div id="divPoints"></div>
@Html.Hidden("newpoints", Model)

If you have a Style component that you can require from your Component, then you could have something like this at the top of the file:

const Dimensions = require('Dimensions');

const window = Dimensions.get('window');

And then you could provide fulscreen: {width: window.width, height: window.height}, in your Style component. Hope this helps

You can center a view as a percentage of the screen size.

This example uses 50% of width and height:

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:background="#FF0000"
        android:orientation="vertical"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintHeight_percent=".5"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintWidth_percent=".5"></LinearLayout>

</android.support.constraint.ConstraintLayout>

This was done using ConstraintLayout version 1.1.3. Don't forget to add it to your dependencies in the gradle, and increase the version if there is a new version out there:

dependencies {
...
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
}

i know this is an old post, but wanted to share how i solved the same problem.

My image was inheriting a float:left from a parent class. By setting float:none I was able to make margin:0 auto and display: block work properly. Hope it may help someone in the future.

For MySQL Workbench 6.1: in the home window click on the server instance(connection)/ or create a new one. In the thus opened 'connection' tab click on 'server' -> 'data import'. The rest of the steps remain as in Vishy's answer.

Opening CMD in the location of the already installed request folder and running "pip install requests" worked for me. I am using two different versions of Python.

I think this works because requests is now installed outside my virtual environment. Haven't checked but just thought I'd write this in, in case anyone else is going crazy searching on Google.

Take a look at the history of "foobar" on Wikipedia.

It is not the asker's problem in this instance but the first troubleshooting step for a generic "AttributeError: __exit__" should be making sure the brackets are there, e.g.

with SomeContextManager() as foo:
    #works because a new object is referenced...

not

with SomeContextManager as foo:
    #AttributeError because the class is referenced

Catches me out from time to time and I end up here -__-

How about some simple testing? Used the code below:

long start = System.currentTimeMillis();

String a = "a";

String b = "b";

for (int i = 0; i < 10000000; i++) { //ten million times
     String c = a.concat(b);
}

long end = System.currentTimeMillis();

System.out.println(end - start);

• The "a + b" version executed in 2500ms.
• The a.concat(b) executed in 1200ms.

Tested several times. The concat() version execution took half of the time on average.

This result surprised me because the concat() method always creates a new string (it returns a "new String(result)". It's well known that:

String a = new String("a") // more than 20 times slower than String a = "a"

Why wasn't the compiler capable of optimize the string creation in "a + b" code, knowing the it always resulted in the same string? It could avoid a new string creation. If you don't believe the statement above, test for your self.

You need To use then() function, like this

swal({
    title: "Are you sure?",
    text: "You will not be able to recover this imaginary file!",
    type: "warning",
    showCancelButton: true,
    confirmButtonColor: '#DD6B55',
    confirmButtonText: 'Yes, I am sure!',
    cancelButtonText: "No, cancel it!"
 }).then(
       function () { /*Your Code Here*/ },
       function () { return false; });

Here's a variant on mkh's answer that runs much faster than it, and scipy.stats.pearsonr, using numba.

import numba

def corr(data1, data2):
    M = data1.size

    sum1 = 0.
    sum2 = 0.
    for i in range(M):
        sum1 += data1[i]
        sum2 += data2[i]
    mean1 = sum1 / M
    mean2 = sum2 / M

    var_sum1 = 0.
    var_sum2 = 0.
    cross_sum = 0.
    for i in range(M):
        var_sum1 += (data1[i] - mean1) ** 2
        var_sum2 += (data2[i] - mean2) ** 2
        cross_sum += (data1[i] * data2[i])

    std1 = (var_sum1 / M) ** .5
    std2 = (var_sum2 / M) ** .5
    cross_mean = cross_sum / M

    return (cross_mean - mean1 * mean2) / (std1 * std2)

or try this: HTML Table Export

In order to insert the text from activity2 to activity1, you first need to create a visit function in activity2.

public void visitactivity1()
{
    Intent i = new Intent(this, activity1.class);
    i.putExtra("key", message);
    startActivity(i);
}

After creating this function, you need to call it from your onCreate() function of activity2:

visitactivity1();

Next, go on to the activity1 Java file. In its onCreate() function, create a Bundle object, fetch the earlier message via its key through this object, and store it in a String.

    Bundle b = getIntent().getExtras();
    String message = b.getString("key", ""); // the blank String in the second parameter is the default value of this variable. In case the value from previous activity fails to be obtained, the app won't crash: instead, it'll go with the default value of an empty string

Now put this element in a TextView or EditText, or whichever layout element you prefer using the setText() function.

Specific to XCode 9.1:
You can refere to @Krunal's answer above or follow below steps

its bit tricky to adjust Simulator size.

If you want to zoom your simulator screen follow below steps :

• Goto Window->Uncheck Show Device Bezels

• Goto Window->select zoom

after doing this you can resize your simulator by dragging edges of simulator.

Pixel Accurate : Its to display your simulator in same size as Physical device pixels, if your screen size doesn't have enough resolution to cover dimension it would not enable Pixel Accurate option.

Alternate is change simulator to landscape mode by clicking ? + ? ,then you could click ? + 2 to select Pixel Accurate option (make sure you have disable Show Device Bezels to reduce size.

None of the above worked for me on an Ubuntu 18.04 fresh install via docker image.

The following solved it for me:

apt-get install holland python3-mysqldb

You must have packaged the servlet-api.jar along with the other libraries in your war file. You can verify this by opening up your war file and navigating to the WEB-INF/lib folder.

Ideally, you should not provide the servlet-api jar. The container, in your case Tomcat, is responsible for providing it at deploy time to your application. If you try to provide it as well, then issues arise due to version mismatch etc. Best practise is to just avoid packaging it. Remove it from the WEB-INF/lib.

Additional Information

If you are using maven for your packaging, then simply add the provided tag with the dependency and maven will make sure not to package it in the final war file. Something like

<dependency>
    <artifact>..
    <group> ...
    <version> ...
    <scope>provided</scope>
</<dependency>

To receive arbitrary Json in Spring-Boot, you can simply use Jackson's JsonNode. The appropriate converter is automatically configured.

    @PostMapping(value="/process")
    public void process(@RequestBody com.fasterxml.jackson.databind.JsonNode payload) {
        System.out.println(payload);
    }

Without using inline CSS you could set the text size of all your buttons using:

input[type="submit"], input[type="button"] {
  font-size: 14px;
}

EXEC sp_spaceused @oneresultset = 1 show in 1 row all of the result

if you execute just 'EXEC sp_spaceused' you will see two rows Work in SQL Server Management Studio v17.9

You can try this query:

Select A.*, (select count(*) from Table1 where A.ID>=ID) as RowNo
from Table1 as A
order by A.ID

    String path = Server.MapPath("~/MP_Upload/");
    if (!Directory.Exists(path))
    {
        Directory.CreateDirectory(path);
    }

To write inline styling use:

<div style="height: 100px;">
asdfashdjkfhaskjdf
</div>

Inline styling serves a purpose however, it is not recommended in most situations.

The more "proper" solution, would be to make a separate CSS sheet, include it in your HTML document, and then use either an ID or a class to reference your div.

if you have the file structure:

index.html
>>/css/
>>/css/styles.css

Then in your HTML document between <head> and </head> write:

<link href="css/styles.css" rel="stylesheet" />

Then, change your div structure to be:

<div id="someidname" class="someclassname">
    asdfashdjkfhaskjdf
</div>

In css, you can reference your div from the ID or the CLASS.

To do so write:

.someclassname { height: 100px; }

OR

#someidname { height: 100px; }

Note that if you do both, the one that comes further down the file structure will be the one that actually works.

For example... If you have:

.someclassname { height: 100px; }

.someclassname { height: 150px; }

Then in this situation the height will be 150px.

EDIT:

To answer your secondary question from your edit, probably need overflow: hidden; or overflow: visible; . You could also do this:

<div class="span12">
    <div style="height:100px;">
        asdfashdjkfhaskjdf
    </div>
</div>

The solutions I've seen are from the perspective of adding javascript features to a theme. However, the OP asked, specifically, "How exactly do I add it for a single WordPress page?" This sounds like it might be how I use javascript in my Wordpress blog, where individual posts may have different javascript-powered "widgets". For instance, a post might let the user change variables (sliders, checkboxes, text input fields), and plots or lists the results.

Starting from the JavaScript perspective:

1. Write your JavaScript functions in a separate “.js” file

Don’t even think about including significant JavaScript in your post’s html—create a JavaScript file, or files, with your code.

2. Interface your JavaScript with your post's html

If your JavaScript widget interacts with html controls and fields, you’ll need to understand how to query and set those elements from JavaScript, and also how to let UI elements call your JavaScript functions. Here are a couple of examples; first, from JavaScript:

var val = document.getElementById(“AM_Freq_A_3”).value;

And from html:

<input type="range" id="AM_Freq_A_3" class="freqSlider" min="0" max="1000" value="0" oninput='sliderChanged_AM_widget(this);'/>

3. Use jQuery to call your JavaScript widget’s initialization function

Add this to your .js file, using the name of your function that configures and draws your JavaScript widget when the page is ready for it:

jQuery(document).ready(function( $ ) {
    your_init_function();
});

4. In your post’s html code, load the scripts needed for your post

In the Wordpress code editor, I typically specify the scripts at the end of the post. For instance, I have a scripts folder in my main directory. Inside I have a utilities directory with common JavaScript that some of my posts may share—in this case some of my own math utility function and the flotr2 plotting library. I find it more convenient to group the post-specific JavaScript in another directory, with subdirectories based on date instead of using the media manager, for instance.

<script type="text/javascript" src="/scripts/utils/flotr2.min.js"></script>
<script type="text/javascript" src="/scripts/utils/math.min.js"></script>
<script type="text/javascript" src="/scripts/widgets/20161207/FreqRes.js"></script>

5. Enqueue jQuery

Wordpress registers jQuery, but it isn’t available unless you tell Wordpress you need it, by enqueuing it. If you don’t, the jQuery command will fail. Many sources tell you how to add this command to your functions.php, but assume you know some other important details.

First, it’s a bad idea to edit a theme—any future update of the theme will wipe out your changes. Make a child theme. Here’s how:

https://developer.wordpress.org/themes/advanced-topics/child-themes/

The child’s functions.php file does not override the parent theme’s file of the same name, it adds to it. The child-themes tutorial suggest how to enqueue the parent and child style.css file. We can simply add another line to that function to also enqueue jQuery. Here's my entire functions.php file for the child theme:

<?php
add_action( 'wp_enqueue_scripts', 'earlevel_scripts_enqueue' );
function earlevel_scripts_enqueue() {
    // styles
    $parent_style = 'parent-style';
    wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css' );
    wp_enqueue_style( 'child-style',
        get_stylesheet_directory_uri() . '/style.css',
        array( $parent_style ),
        wp_get_theme()->get('Version')
    );

    // posts with js widgets need jquery
    wp_enqueue_script('jquery');
}

You had better use find_library command instead of link_directories. Concretely speaking there are two ways:

1. designate the path within the command

   find_library(NAMES gtest PATHS path1 path2 ... pathN)

2. set the variable CMAKE_LIBRARY_PATH

   set(CMAKE_LIBRARY_PATH path1 path2)
   find_library(NAMES gtest)

the reason is as flowings:

Note This command is rarely necessary and should be avoided where there are other choices. Prefer to pass full absolute paths to libraries where possible, since this ensures the correct library will always be linked. The find_library() command provides the full path, which can generally be used directly in calls to target_link_libraries(). Situations where a library search path may be needed include: Project generators like Xcode where the user can switch target architecture at build time, but a full path to a library cannot be used because it only provides one architecture (i.e. it is not a universal binary).

Libraries may themselves have other private library dependencies that expect to be found via RPATH mechanisms, but some linkers are not able to fully decode those paths (e.g. due to the presence of things like $ORIGIN).

If a library search path must be provided, prefer to localize the effect where possible by using the target_link_directories() command rather than link_directories(). The target-specific command can also control how the search directories propagate to other dependent targets.

This might be due to your Antivirus software. If you can not disable AV then you can try modifying your NPM global install location as node installs into APPDATA directory which is actively monitored by AV Engines. Try running following commands-

npm config set prefix "YOUR CUSTOM LOCATION" npm config set cache "YOUR CUSTOM LOCATION"

Delete node_modules directory and install your package again.

Void pointers can point to any memory chunk. Hence the compiler does not know how many bytes to increment/decrement when we attempt pointer arithmetic on a void pointer. Therefore void pointers must be first typecast to a known type before they can be involved in any pointer arithmetic.

void *p = malloc(sizeof(char)*10);
p++; //compiler does how many where to pint the pointer after this increment operation

char * c = (char *)p;
c++;  // compiler will increment the c by 1, since size of char is 1 byte.

To get the format you want:

SELECT (substring(CONVERT(VARCHAR,GETDATE(),22),10,8) + ' ' + SUBSTRING(CONVERT(VARCHAR,getdate(),22), 19,2))

Why are you pulling this from sql?

It is not possible. §2.3 says that "." is an unreserved character and that "URIs that differ in the replacement of an unreserved character with its corresponding percent-encoded US-ASCII octet are equivalent". Therefore, /%2E%2E/ is the same as /../, and that will get normalized away.

(This is a combination of an answer by bobince and a comment by slowpoison.)

Solr I am not sure but you can delete all the data from hbase using truncate command like below:

truncate 'table_name'

It will delete all row-keys from hbase table.

According to the C99 spec,

• NULL expands to a null pointer constant, which is not required to be, but typically is of type void *
• '\0' is a character constant; character constants are of type int, so it's equivalen to plain 0
• "\0" is a null-terminated string literal and equivalent to the compound literal (char [2]){ 0, 0 }

NULL, '\0' and 0 are all null pointer constants, so they'll all yield null pointers on conversion, whereas "\0" yields a non-null char * (which should be treated as const as modification is undefined); as this pointer may be different for each occurence of the literal, it can't be used as sentinel value.

Although you may use any integer constant expression of value 0 as a null pointer constant (eg '\0' or sizeof foo - sizeof foo + (int)0.0), you should use NULL to make your intentions clear.

put the table inside the div to make scrollable table vertically. change overflow-yto overflow-x to make table scrollable horizontally. just overflow to make table scrollable both horizontal and vertical.

<div style="overflow-y: scroll;"> 
    <table>
    ...
    </table>
</div>

Using set(...) makes the code slightly slower, and is only really necessary for when you check the square root. Here's my version:

def factors(num):
    if (num == 1 or num == 0):
        return []
    f = [1]
    sq = int(math.sqrt(num))
    for i in range(2, sq):
        if num % i == 0:
            f.append(i)
            f.append(num/i)
    if sq > 1 and num % sq == 0:
        f.append(sq)
        if sq*sq != num:
            f.append(num/sq)
    return f

The if sq*sq != num: condition is necessary for numbers like 12, where the square root is not an integer, but the floor of the square root is a factor.

Note that this version doesn't return the number itself, but that is an easy fix if you want it. The output also isn't sorted.

I timed it running 10000 times on all numbers 1-200 and 100 times on all numbers 1-5000. It outperforms all the other versions I tested, including dansalmo's, Jason Schorn's, oxrock's, agf's, steveha's, and eryksun's solutions, though oxrock's is by far the closest.

System.Environment has WorkingSet- a 64-bit signed integer containing the number of bytes of physical memory mapped to the process context.

If you want a lot of details there is System.Diagnostics.PerformanceCounter, but it will be a bit more effort to setup.

The easiest way is to just learn how to do DOM traversing and manipulation with the plain DOM api (you would probably call this: normal JavaScript).

This can however be a pain for some things. (which is why libraries were invented in the first place).

Googling for "javascript DOM traversing/manipulation" should present you with plenty of helpful (and some less helpful) resources.

The articles on this website are pretty good: http://www.htmlgoodies.com/primers/jsp/

And as Nosredna points out in the comments: be sure to test in all browsers, because now jQuery won't be handling the inconsistencies for you.

Mine started working when I set AllowDBNull to True on a date field on a data table in the xsd file.

const

public const string MyStr;

is a compile time constant (you can use it as the default parameter for a method parameter for example), and it will not be obfuscated if you use such technology

static readonly

public static readonly string MyStr;

is runtime constant. It means that it is evaluated when the application is launched and not before. This is why it can't be used as the default parameter for a method (compilation error) for example. The value stored in it can be obfuscated.

git diff --name-only SHA1 SHA2

where you only need to include enough of the SHA to identify the commits. You can also do, for example

git diff --name-only HEAD~10 HEAD~5

to see the differences between the tenth latest commit and the fifth latest (or so).

In My Case, I have a close tab of Home Page. After Re-opening the Jupyter.The Error was automatically gone and We can save the file.

I was not using grid or pack.
I used just place for my widgets as their size and positioning was fixed.
I wanted to implement hide/show functionality on frame.
Here is demo

from tkinter import *
window=Tk()
window.geometry("1366x768+1+1")
def toggle_graph_visibility():
    graph_state_chosen=show_graph_checkbox_value.get()
    if graph_state_chosen==0:
        frame.place_forget()
    else:
        frame.place(x=1025,y=165)
score_pixel = PhotoImage(width=300, height=430)
show_graph_checkbox_value = IntVar(value=1)
frame=Frame(window,width=300,height=430)
graph_canvas = Canvas(frame, width = 300, height = 430,scrollregion=(0,0,300,300))
my_canvas=graph_canvas.create_image(20, 20, anchor=NW, image=score_pixel)
vbar=Scrollbar(frame,orient=VERTICAL)
vbar.config(command=graph_canvas.yview)
vbar.pack(side=RIGHT,fill=Y)
graph_canvas.config(yscrollcommand=vbar.set)
graph_canvas.pack(side=LEFT,expand=True,fill=BOTH)
frame.place(x=1025,y=165)
Checkbutton(window, text="show graph",variable=show_graph_checkbox_value,command=toggle_graph_visibility).place(x=900,y=165)
window.mainloop()

Note that in above example when 'show graph' is ticked then there is vertical scrollbar.
Graph disappears when checkbox is unselected.
I was fitting some bar graph in that area which I have not shown to keep example simple.
Most important thing to learn from above is the use of frame.place_forget() to hide and frame.place(x=x_pos,y=y_pos) to show back the content.

Right!!! after much hair pulling I've finally worked out how to make this work properly.

It seems as though fragment [3] is not removed from the view when back is pressed so you have to do it manually!

First of all, dont use replace() but instead use remove and add separately. It seems as though replace() doesnt work properly.

The next part to this is overriding the onKeyDown method and remove the current fragment every time the back button is pressed.

@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
    if (keyCode == KeyEvent.KEYCODE_BACK)
    {
        if (getSupportFragmentManager().getBackStackEntryCount() == 0)
        {
            this.finish();
            return false;
        }
        else
        {
            getSupportFragmentManager().popBackStack();
            removeCurrentFragment();

            return false;
        }



    }

    return super.onKeyDown(keyCode, event);
}


public void removeCurrentFragment()
{
    FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();

    Fragment currentFrag =  getSupportFragmentManager().findFragmentById(R.id.detailFragment);


    String fragName = "NONE";

    if (currentFrag!=null)
        fragName = currentFrag.getClass().getSimpleName();


    if (currentFrag != null)
        transaction.remove(currentFrag);

    transaction.commit();

}

Hope this helps!

I also suggest using contourf(Z). For my problem, I wanted to visualize a 3D histogram in 2D, but the contours were too smooth to represent a top view of histogram bars.

So in my case, I prefer to use jucestain's answer. The default shading faceted of pcolor() is more suitable. However, pcolor() does not use the last row and column of the plotted matrix. For this, I used the padarray() function:

pcolor(padarray(Z,[1 1],0,'post'))

Sorry if that is not really related to the original post

window.location.replace is the best way to emulate a redirect:

function ShowComments(){
    var movieShareId = document.getElementById('movieId');
    window.location.replace("/comments.aspx?id=" + (movieShareId.textContent || movieShareId.innerText) + "/");
}

More information about why window.location.replace is the best javascript redirect can be found right here.

It can be especially difficult to delete a module if it is not pure Python.

Here is some information from: How do I really delete an imported module?

You can use sys.getrefcount() to find out the actual number of references.

>>> import sys, empty, os
>>> sys.getrefcount(sys)
9
>>> sys.getrefcount(os)
6
>>> sys.getrefcount(empty)
3

Numbers greater than 3 indicate that it will be hard to get rid of the module. The homegrown "empty" (containing nothing) module should be garbage collected after

>>> del sys.modules["empty"]
>>> del empty

as the third reference is an artifact of the getrefcount() function.

One more solution:

#footer { display:table; margin:0 auto; }
#footer li { display:table-cell; padding: 0px 10px; }

Then ul doesn't jump to the next line in case of zooming text.

Thank you for your help @jezrael, @zipa and @everestial007, both answers are what I need. If I wanted to make a recursive, this would also work as intended:

def mergefiles(dfs=[], on=''):
    """Merge a list of files based on one column"""
    if len(dfs) == 1:
         return "List only have one element."

    elif len(dfs) == 2:
        df1 = dfs[0]
        df2 = dfs[1]
        df = df1.merge(df2, on=on)
        return df

    # Merge the first and second datafranes into new dataframe
    df1 = dfs[0]
    df2 = dfs[1]
    df = dfs[0].merge(dfs[1], on=on)

    # Create new list with merged dataframe
    dfl = []
    dfl.append(df)

    # Join lists
    dfl = dfl + dfs[2:] 
    dfm = mergefiles(dfl, on)
    return dfm

You can't call "printf" with a std::string in parameter. The "%s" is designed for C-style string : char* or char []. In C++ you can do like that :

#include <iostream>
std::cout << YourString << std::endl;

If you absolutely want to use printf, you can use the "c_str()" method that give a char* representation of your string.

printf("%s\n",YourString.c_str())

I had the same problem as you. After a long time spent Googling, I found out my error was caused by multiple users that had added the same key in their accounts.

So, here is my solution: delete the wrong-user's ssh-key (I can do it because the wrong-user is also my account). If the wrong-user isn't your account, you may need to change your ssh-key, but I don't think this gonna happen.

And I think your problem may be caused by a mistyping error in your accounts name.

Depending on the situation and or your style, you might also wanna use print inside your <% %> tags, as it allows for direct output. Like:

<% if (typeof(id) != "undefined") {
     print(id);
}
else {
    print('new Model');
} %>

And for the original snippet with some concatenation:

<% if (typeof(date) != "undefined") {
    print('<span class="date">' + date + '</span>');
} %>

This is how I manage to "download" it:

1. Use inspect-element to identify the URL of the M3U playlist file
2. Download the M3U file
3. Use VLC to read the M3U file, stream and convert the video to MP4

In Firefox the M3U file appeared as of type application/vnd.apple.mpegurl

The contents of the M3U file would look like:

Open VLC medial player and use the Media => Convert option. Use your (saved) M3U file as the source:

It means that trackDAO should not be serialized.

When you put the username and password in front of the host, this data is not sent that way to the server. It is instead transformed to a request header depending on the authentication schema used. Most of the time this is going to be Basic Auth which I describe below. A similar (but significantly less often used) authentication scheme is Digest Auth which nowadays provides comparable security features.

With Basic Auth, the HTTP request from the question will look something like this:

GET / HTTP/1.1
Host: example.com
Authorization: Basic Zm9vOnBhc3N3b3Jk

The hash like string you see there is created by the browser like this: base64_encode(username + ":" + password).

To outsiders of the HTTPS transfer, this information is hidden (as everything else on the HTTP level). You should take care of logging on the client and all intermediate servers though. The username will normally be shown in server logs, but the password won't. This is not guaranteed though. When you call that URL on the client with e.g. curl, the username and password will be clearly visible on the process list and might turn up in the bash history file.

When you send passwords in a GET request as e.g. http://example.com/login.php?username=me&password=secure the username and password will always turn up in server logs of your webserver, application server, caches, ... unless you specifically configure your servers to not log it. This only applies to servers being able to read the unencrypted http data, like your application server or any middleboxes such as loadbalancers, CDNs, proxies, etc. though.

Basic auth is standardized and implemented by browsers by showing this little username/password popup you might have seen already. When you put the username/password into an HTML form sent via GET or POST, you have to implement all the login/logout logic yourself (which might be an advantage and allows you to more control over the login/logout flow for the added "cost" of having to implement this securely again). But you should never transfer usernames and passwords by GET parameters. If you have to, use POST instead. The prevents the logging of this data by default.

When implementing an authentication mechanism with a user/password entry form and a subsequent cookie-based session as it is commonly used today, you have to make sure that the password is either transported with POST requests or one of the standardized authentication schemes above only.

Concluding I could say, that transfering data that way over HTTPS is likely safe, as long as you take care that the password does not turn up in unexpected places. But that advice applies to every transfer of any password in any way.

Name:

abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!#$%&'*+-/=?^_`{|}~.

Server:

abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-.

Try This. You need pass the authentication to let the server know its a valid user. You need to import these two packages and has to include a jersy jar. If you dont want to include jersy jar then import this package

import sun.misc.BASE64Encoder;

import com.sun.jersey.core.util.Base64;
import sun.net.www.protocol.http.HttpURLConnection;

and then,

String encodedAuthorizedUser = getAuthantication("username", "password");
URL url = new URL("Your Valid Jira URL");
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setRequestProperty ("Authorization", "Basic " + encodedAuthorizedUser );

 public String getAuthantication(String username, String password) {
   String auth = new String(Base64.encode(username + ":" + password));
   return auth;
 }

If you specify @GET("foobar?a=5"), then any @Query("b") must be appended using &, producing something like foobar?a=5&b=7.

If you specify @GET("foobar"), then the first @Query must be appended using ?, producing something like foobar?b=7.

That's how Retrofit works.

When you specify @GET("foobar?"), Retrofit thinks you already gave some query parameter, and appends more query parameters using &.

Remove the ?, and you will get the desired result.

Firstly It tries insert. If there is a conflict on url column then it updates content and last_analyzed fields. If updates are rare this might be better option.

INSERT INTO URLs (url, content, last_analyzed)
VALUES
    (
        %(url)s,
        %(content)s,
        NOW()
    ) 
ON CONFLICT (url) 
DO
UPDATE
SET content=%(content)s, last_analyzed = NOW();

Here is the solutions that worked for me:

1. open index.php from the htdocs folder
2. inside replace the word dashboard with your database name.
3. restart the server

This should resolve the issue :-)

To convert a string to lower case in Python, use something like this.

list.append(sentence.lower())

I found this in the first result after searching for "python upper to lower case".

Try this:

net use * /delete /y

The /y key makes it select Yes in prompt silently

1. assign

   • assign is a default property attribute
   • assign is a property attribute tells the compiler how to synthesize the property’s setter implementation

2. copy:

   • copy is required when the object is mutable
   • copy returns an object which you must explicitly release (e.g., in dealloc) in non-garbage collected environments
   • you need to release the object when finished with it because you are retaining the copy

3. retain:

   • specifies the new value should be sent “-retain” on assignment and the old value sent “-release”
   • if you write retain it will auto work like strong
   • Methods like “alloc” include an implicit “retain”

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

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

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

It is possible to use full C# 6.0 features in Visual Studio 2013 if you have Resharper.
You have to enable Resharper Build and voilá! In Resharper Options -> Build - enable Resharper Build and in "Use MSBuild.exe version" choose "Latest Installed"

This way Resharper is going to build your C# 6.0 Projects and will also not underline C# 6.0 code as invalid.

I am also using this although I have Visual Studio 2015 because:

1. Unit Tests in Resharper don't work for me with Visual Studio 2015 for some reason
2. VS 2015 uses a lot more memory than VS 2013.

I am putting this here, as I was looking for a solution for this problem for some time now and maybe it will help someone else.

These lines did the trick for all other deprecation warnings too:

const db = await mongoose.createConnection(url, { useNewUrlParser: true });
mongoose.set('useCreateIndex', true);
mongoose.set('useFindAndModify', false);

I had almost the same example as you in this notebook where I wanted to illustrate the usage of an adjacent module's function in a DRY manner.

My solution was to tell Python of that additional module import path by adding a snippet like this one to the notebook:

import os
import sys
module_path = os.path.abspath(os.path.join('..'))
if module_path not in sys.path:
    sys.path.append(module_path)

This allows you to import the desired function from the module hierarchy:

from project1.lib.module import function
# use the function normally
function(...)

Note that it is necessary to add empty __init__.py files to project1/ and lib/ folders if you don't have them already.

From back side with Spring Boot I've used custom BasicAuthenticationEntryPoint:

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.cors().and().authorizeRequests()
            ...
            .antMatchers(PUBLIC_AUTH).permitAll()
            .and().httpBasic()
//    https://www.baeldung.com/spring-security-basic-authentication
            .authenticationEntryPoint(authBasicAuthenticationEntryPoint())
            ...

@Bean
public BasicAuthenticationEntryPoint authBasicAuthenticationEntryPoint() {
    return new BasicAuthenticationEntryPoint() {
        {
            setRealmName("pirsApp");
        }

        @Override
        public void commence
                (HttpServletRequest request, HttpServletResponse response, AuthenticationException authEx)
                throws IOException, ServletException {
            if (request.getRequestURI().equals(PUBLIC_AUTH)) {
                response.sendError(HttpStatus.PRECONDITION_FAILED.value(), "Wrong credentials");
            } else {
                super.commence(request, response, authEx);
            }
        }
    };
}

You don't have to restart the PC. Restart IIS instead.

Run -> 'cmd'(as admin) and type "iisreset"

var list = new List<string>();
var queryable = list.AsQueryable();

Add a reference to: System.Linq

The problem is that "i" is incremented, so by the time the click event is executed the value of i equals len. One possible solution is to capture the value of i inside a function:

var len = menuitems.length;
for (var i = 0; i < len; i++){
    (function(i) {
      $('<li/>',{
          'html':'<img src="'+menuitems[i].icon+'">'+menuitems[i].name,
          'click':function(){
              menuitems[i].action();
          },
          'class':o.itemClass
      }).appendTo('.'+o.listClass);
    })(i);
}

In the above sample, the anonymous function creates a new scope which captures the current value of i, so that when the click event is triggered the local variable is used instead of the i from the for loop.

change your code to:

function ChangePurpose(Vid, PurId) {
    var Success = false;
    $.ajax({
        type: "POST",
        url: "CHService.asmx/SavePurpose",
        dataType: "text",
        async: false,
        data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
        contentType: "application/json; charset=utf-8",
        success: function (data) {
            Success = true;
        },
        error: function (textStatus, errorThrown) {
            Success = false;
        }
    });
    //done after here
    return Success;
} 

You can only return the values from a synchronous function. Otherwise you will have to make a callback.

So I just added async:false, to your ajax call

Update:

jquery ajax calls are asynchronous by default. So success & error functions will be called when the ajax load is complete. But your return statement will be executed just after the ajax call is started.

A better approach will be:

     // callbackfn is the pointer to any function that needs to be called
     function ChangePurpose(Vid, PurId, callbackfn) {
        var Success = false;
        $.ajax({
            type: "POST",
            url: "CHService.asmx/SavePurpose",
            dataType: "text",
            data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
            contentType: "application/json; charset=utf-8",
            success: function (data) {
                callbackfn(data)
            },
            error: function (textStatus, errorThrown) {
                callbackfn("Error getting the data")
            }
        });
     } 

     function Callback(data)
     {
        alert(data);
     }

and call the ajax as:

 // Callback is the callback-function that needs to be called when asynchronous call is complete
 ChangePurpose(Vid, PurId, Callback);

As the other poster mention, py2exe, will generate an executable + some libraries to load. You can also have some data to add to your program.

Next step is to use an installer, to package all this into one easy-to-use installable/unistallable program.

I have used InnoSetup with delight for several years and for commercial programs, so I heartily recommend it.

Should use ngChange instead of ngClick if trigger source is not from click.

Is the below what you want ? what exactly doesn't work in your case ?

var myApp = angular.module('myApp', []);

function MyCtrl($scope) {
    $scope.value = "none" ;
    $scope.isChecked = false;
    $scope.checkStuff = function () {
        $scope.isChecked = !$scope.isChecked;
    }
}


<div ng-controller="MyCtrl">
    <input type="radio" ng-model="value" value="one" ng-change="checkStuff()" />
    <span> {{value}} isCheck:{{isChecked}} </span>
</div>   

You can use c++ boost::property_tree::ptree for parsing json data. here is the example for your json data. this would be more easy if you shift name inside each child nodes

#include <iostream>

#include <tuple>

It's a difference between RDBMS's varchar (or similar) — those are usually specified with a maximum length, and might be more efficient in terms of performance or storage — and text (or similar) types — those are usually limited only by hardcoded implementation limits (not a DB schema).

PostgreSQL 9, specifically, states that "There is no performance difference among these three types", but AFAIK there are some differences in e.g. MySQL, so this is something to keep in mind.

A good rule of thumb is that you use CharField when you need to limit the maximum length, TextField otherwise.

This is not really Django-specific, also.

The getRequestURL() omits the port when it is 80 while the scheme is http, or when it is 443 while the scheme is https.

So, just use getRequestURL() if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:

StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
    requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();

I could see that there is a better library than the apache commons exec library. You can execute your job using Java Secure Shell (JSch).

I had the same problem. I used JSch to solve this problem. Apache commons had some issues running commands on a different server. Plus JSch gave me result and errors InputStreams. I found it more elegant. Sample solution can be found here : http://wiki.jsch.org/index.php?Manual%2FExamples%2FJschExecExample

http://msdn.microsoft.com/en-us/library/bb342261.aspx

The historical reason to define height/width in tags is so that browsers can size the actual <img> elements in the page even before the CSS and/or image resources are loaded. If you do not supply height and width explicitly the <img> element will be rendered at 0x0 until the browser can size it based on the file. When this happens it causes a visual reflow of the page once the image loads, and is compounded if you have multiple images on the page. Sizing the <img> via height/width creates a physical placeholder in the page flow at the correct size, enabling your content to load asynchronously without disrupting the user experience.

Alternately, if you are doing mobile-responsive design, which is a best practice these days, it's quite common to specify a width (or max-width) only and define the height as auto. That way when you define media queries (e.g. CSS) for different screen widths, you can simply adjust the image width and let the browser deal with keeping the image height / aspect ratio correct. This is sort of a middle ground approach, as you may get some reflow, but it allows you to support a broad range of screen sizes, so the benefit usually outweighs the negative.

Finally, there are times when you may not know the image size ahead of time (image src might be loaded dynamically, or can change during the lifetime of the page via script) in which case using CSS only makes sense.

The bottom line is that you need to understand the trade-offs and decide which strategy makes the most sense for what you're trying to achieve.

Basically

A responsive table is simply a 100% width table.

You can just set up your table with this CSS:

.table { width: 100%; }

Demo here

You can use media queries to show/hide/manipulate columns according to the screens dimensions by adding a class (or targeting using nth-child, etc):

@media screen and (max-width: 320px) {
    .hide { display: none; }
}

HTML

<td class="hide">Not important</td>

More advanced solutions

If you have a table with a lot of data and you would like to make it readable on small screen devices there are many other solutions:

• css-tricks.com offers up this article for handling large data tables.
• Zurb also ran into this issue and solved it using javascript.
• Footables is a great jQuery plugin that also helps you out with this issue.
• As posted by Elvin Arzumanoglu this is a great list of examples.

$text="abc1234567890";

// truncate to 4 chars

echo substr(str_pad($text,4),0,4);

This avoids the problem of truncating a 4 char string to 10 chars .. (i.e. source is smaller than the required)

Here is a complete, very simple .Net solution that works in all versions of windows. Simply paste it into a new project, run it and try CTRL-C to view how it handles it:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading;

namespace TestTrapCtrlC{
    public class Program{
        static bool exitSystem = false;

        #region Trap application termination
        [DllImport("Kernel32")]
        private static extern bool SetConsoleCtrlHandler(EventHandler handler, bool add);

        private delegate bool EventHandler(CtrlType sig);
        static EventHandler _handler;

        enum CtrlType {
         CTRL_C_EVENT = 0,
         CTRL_BREAK_EVENT = 1,
         CTRL_CLOSE_EVENT = 2,
         CTRL_LOGOFF_EVENT = 5,
         CTRL_SHUTDOWN_EVENT = 6
         }

        private static bool Handler(CtrlType sig) {
            Console.WriteLine("Exiting system due to external CTRL-C, or process kill, or shutdown");

            //do your cleanup here
            Thread.Sleep(5000); //simulate some cleanup delay

            Console.WriteLine("Cleanup complete");

            //allow main to run off
             exitSystem = true;

            //shutdown right away so there are no lingering threads
            Environment.Exit(-1);

            return true;
        }
        #endregion

        static void Main(string[] args) {
            // Some biolerplate to react to close window event, CTRL-C, kill, etc
            _handler += new EventHandler(Handler);
            SetConsoleCtrlHandler(_handler, true);

            //start your multi threaded program here
            Program p = new Program();
            p.Start();

            //hold the console so it doesn’t run off the end
            while(!exitSystem) {
                Thread.Sleep(500);
            }
        }

        public void Start() {
            // start a thread and start doing some processing
            Console.WriteLine("Thread started, processing..");
        }
    }
 }

To replace a character at a specified position :

public static String replaceCharAt(String s, int pos, char c) {
   return s.substring(0,pos) + c + s.substring(pos+1);
}

You can try:

WebElement getmenu= driver.findElement(By.xpath("//*[@id='ui-id-2']/span[2]")); //xpath the parent

Actions act = new Actions(driver);
act.moveToElement(getmenu).perform();

Thread.sleep(3000);
WebElement clickElement= driver.findElement(By.linkText("Sofa L"));//xpath the child
act.moveToElement(clickElement).click().perform();

If you had case the web have many category, use the first method. For menu you wanted, you just need the second method.

In case someone else finds this thread when Googling, like I did:

I had what appeared to be the same problem for a while, and after some digging I noticed that the R.java file got correctly built, but was ignored for only one of my source files. The problem for this particular file was that Eclipse had "helpfully" added the following line at the top:

import android.R;

That effectively hides the project R stuff. Just remove it and everything will be fine again...

I had this issue, and solved. This was due to the WHERE clause contains String value instead of integer value.

TL; DR: use np.where as it is the fastest option. Your options are np.where, itertools.compress, and list comprehension.

See the detailed comparison below, where it can be seen np.where outperforms both itertools.compress and also list comprehension.

>>> from itertools import compress
>>> import numpy as np
>>> t = [False, False, False, False, True, True, False, True, False, False, False, False, False, False, False, False]`
>>> t = 1000*t

• Method 1: Using list comprehension

>>> %timeit [i for i, x in enumerate(t) if x]
457 µs ± 1.5 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

• Method 2: Using itertools.compress

>>> %timeit list(compress(range(len(t)), t))
210 µs ± 704 ns per loop (mean ± std. dev. of 7 runs, 1000 loops each)

• Method 3 (the fastest method): Using numpy.where

>>> %timeit np.where(t)
179 µs ± 593 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)

An easy way is to let PHP create the directory itself in the first place.

<?php
 $dir = 'myDir';

 // create new directory with 744 permissions if it does not exist yet
 // owner will be the user/group the PHP script is run under
 if ( !file_exists($dir) ) {
     mkdir ($dir, 0744);
 }

 file_put_contents ($dir.'/test.txt', 'Hello File');

This saves you the hassle with permissions.

Using split(), you just have to change what you wish to split on.

public static String reverseString(String str)
{
    String[] rstr;
    String result = "";
    int count = 0;
    rstr = str.split(" ");
    String words[] = new String[rstr.length];
    for(int i = rstr.length-1; i >= 0; i--)
    {
        words[count] = rstr[i];
        count++;
    }

    for(int j = 0; j <= words.length-1; j++)
    {
        result += words[j] + " ";
    }

    return result;


}

Bootstrap 3.0 version is tricky they will add fix for this issue and probably return container-fluid in Bootstrap 3.1. But until then here is a fix that I'm using:

First of, you would need custom container and set it to 100% width, and then you will need to fix row margin disposition, and navbar too if you have it:

/* Custom container */
.container-full {
  margin: 0 auto;
  width: 100%;
}

/*fix row -15px margin*/
.container-fluid {
    padding: 0 15px;
}

/*fix navbar margin*/
.navbar{
  margin: 0 -15px;
}

/*fix navbar-right margin*/
.navbar-nav.navbar-right:last-child {
  margin-right: 0px;
}

You can stack container-full and container-fluid classes on root div, and you can use container-fluid later on.

Hope it helps, if you need more info let me know.

putting the UNIX_TIMESTAMP will do the trick.

SELECT id, NAME, form_id, UNIX_TIMESTAMP(updated_at) AS DATE
    FROM wp_frm_items
    WHERE user_id = 11 && form_id=9
    ORDER BY DATE DESC

This could be useful when implementing multiprocessing and parallel/ distributed computing in Python.

YouTube tutorial on using techila package

Techila is a distributed computing middleware, which integrates directly with Python using the techila package. The peach function in the package can be useful in parallelizing loop structures. (Following code snippet is from the Techila Community Forums)

techila.peach(funcname = 'theheavyalgorithm', # Function that will be called on the compute nodes/ Workers
    files = 'theheavyalgorithm.py', # Python-file that will be sourced on Workers
    jobs = jobcount # Number of Jobs in the Project
    )

If you think about it, comparing numbers to logical statements doesn't make much sense. However, since 0 is often associated with "Off" or "False" and 1 with "On" or "True", R has decided to allow 1 == TRUE and 0 == FALSE to both be true. Any other numeric-to-boolean comparison should yield false, unless it's something like 3 - 2 == TRUE.

Thoughts (based on pain in the past):

• do you have DNS and line-of-sight to the server?
• are you using the correct name from the certificate?
• is the certificate still valid?
• is a badly configured load balancer messing things up?
• does the new server machine have the clock set correctly (i.e. so that the UTC time is correct [ignore local time, it is largely irrelevent]) - this certainly matters for WCF, so may impact regular SOAP?
• is there a certificate trust chain issue? if you browse from the server to the soap service, can you get SSL?
• related to the above - has the certificate been installed to the correct location? (you may need a copy in Trusted Root Certification Authorities)
• is the server's machine-level proxy set correctly? (which different to the user's proxy); see proxycfg for XP / 2003 (not sure about Vista etc)

Use innerText/textContent:

  var el = document.getElementById('*spaM4');
  console.log(el.innerText || el.textContent);

If using scala, try priv + tab

After investigating lots of alternatives, I have come across another approach, suitable for the API 2.0 version.

(VB.NET is my favorite, sooo...)

Public Async Function APIPut_Response(ID as Integer, MyWidget as Widget) as Task(Of HttpResponseMessage)
    Dim DesiredContent as HttpContent = New StringContent(JsonConvert.SerializeObject(MyWidget))
    Return Await APIClient.PutAsync(String.Format("api/widget/{0}", ID), DesiredContent)
End Function

Good luck! For me this worked out (in the end!).

Regards, Peter

It doesn't matter - they're both allowed inside each other.

**Old Method:**
if(x){
   add(x);
}
New Method:
x && add(x);

Even assign operation also we can do with round brackets

exp.includes('regexp_replace') && (exp = exp.replace(/,/g, '@&'));

Just with bash:

convert_date () {
    local months=( JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC )
    local i
    for (( i=0; i<11; i++ )); do
        [[ $2 = ${months[$i]} ]] && break
    done
    printf "%4d%02d%02d\n" $3 $(( i+1 )) $1
}

And invoke it like this

d=$( convert_date 27 JUN 2011 )

Or if the "old" date string is stored in a variable

d_old="27 JUN 2011"
d=$( convert_date $d_old )  # not quoted

PHP PMD (Programming Mistake Detector) and PHP CPD (Copy/Paste Detector) as the former part of PHPUnit.

Do simple compare > and <.

if (dateA>dateB && dateA<dateC)
    //do something

If you care only on time:

if (dateA.TimeOfDay>dateB.TimeOfDay && dateA.TimeOfDay<dateC.TimeOfDay)
    //do something

If you are talking about tag stripping, it is relatively straight forward if you don't have to worry about things like <script> tags. If all you need to do is display the text without the tags you can accomplish that with a regular expression:

<[^>]*>

If you do have to worry about <script> tags and the like then you'll need something a bit more powerful then regular expressions because you need to track state, omething more like a Context Free Grammar (CFG). Althought you might be able to accomplish it with 'Left To Right' or non-greedy matching.

If you can use regular expressions there are many web pages out there with good info:

• http://weblogs.asp.net/rosherove/archive/2003/05/13/6963.aspx
• http://www.google.com/search?hl=en&q=html+tag+stripping+&btnG=Search

If you need the more complex behaviour of a CFG I would suggest using a third party tool, unfortunately I don't know of a good one to recommend.

The bottom statement is equivalent to:

.half {
   flex-grow: 0;
   flex-shrink: 0;
   flex-basis: 50%;
}

Which, in this case, would be equivalent as the box is not allowed to flex and therefore retains the initial width set by flex-basis.

Flex-basis defines the default size of an element before the remaining space is distributed so if the element were allowed to flex (grow/shrink) it may not be 50% of the width of the page.

I've found that I regularly return to https://css-tricks.com/snippets/css/a-guide-to-flexbox/ for help regarding flexbox :)

Here's an O(n) solution using reduce and Object.assign

const joinById = ( ...lists ) =>
    Object.values(
        lists.reduce(
            ( idx, list ) => {
                list.forEach( ( recod ) => {
                    if( idx[ recod.id ] )
                        idx[ recod.id ] = Object.assign( idx[ recod.id ], recod )
                    else
                        idx[ recod.id ] = recod
                } )
                return idx
            },
            {}
        )
    )

Each list gets reduced to a single object where the keys are ids and the values are the objects. If there's a value at the given key already, it gets object.assign called on it and the current record.

Here's the generic O(n*m) solution, where n is the number of records and m is the number of keys. This will only work for valid object keys. You can convert any value to base64 and use that if you need to.

const join = ( keys, ...lists ) =>
    lists.reduce(
        ( res, list ) => {
            list.forEach( ( record ) => {
                let hasNode = keys.reduce(
                    ( idx, key ) => idx && idx[ record[ key ] ],
                    res[ 0 ].tree
                )
                if( hasNode ) {
                    const i = hasNode.i
                    Object.assign( res[ i ].value, record )
                    res[ i ].found++
                } else {
                    let node = keys.reduce( ( idx, key ) => {
                        if( idx[ record[ key ] ] )
                            return idx[ record[ key ] ]
                        else
                            idx[ record[ key ] ] = {}
                        return idx[ record[ key ] ]
                    }, res[ 0 ].tree )
                    node.i = res[ 0 ].i++
                    res[ node.i ] = {
                        found: 1,
                        value: record
                    }
                }
            } )
            return res
        },
        [ { i: 1, tree: {} } ]
         )
         .slice( 1 )
         .filter( node => node.found === lists.length )
         .map( n => n.value )

This is essentially the same as the joinById method, except that it keeps an index object to identify records to join. The records are stored in an array and the index stores the position of the record for the given key set and the number of lists it's been found in.

Each time the same key set is encountered, the node is found in the tree, the element at it's index is updated, and the number of times it's been found is incremented.

finally, the idx object is removed from the array with the slice, any elements that weren't found in each set are removed. This makes it an inner join, you could remove this filter and have a full outer join.

finally each element is mapped to it's value, and you have the merged array.

Installing pipenv globally can have an adverse effect by overwriting the global/system-managed pip installation, thus resulting in import errors when trying to run pip.

You can install pipenv at the user level:

pip install --user pipenv

This should install pipenv at a user-level in /home/username/.local so that it does not conflict with the global version of pip. In my case, that still did not work after running the '--user' switch, so I ran the longer 'fix what I screwed up' command once to restore the system managed environment:

sudo python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall

^ found here: Error after upgrading pip: cannot import name 'main'

and then did the following:

mkdir /home/username/.local ... if it doesn't already exist

export PYTHONUSERBASE=/home/username/.local

Make sure the export took effect (bit me once during this process):

echo $PYTHONUSERBASE

Then, I ran the pip install --user pipenv and all was well. I could then run pipenv from the CLI and it did not overwrite the global/system-managed pip module. Of course, this is specific to the user so you want to make sure you install pipenv this way while working as the user you wish to use pipenv.

These two commands will help you find and kill server process

1. lsof -wni tcp:3000
2. kill -9 pid

I just had the same problem and ran into this post. It actually helped me to get it running with the native Send-MailMessage command-let and here is my code:

$cred = Get-Credential
Send-MailMessage ....... -SmtpServer "smtp.gmail.com" -UseSsl -Credential $cred -Port 587 

However, in order to have Gmail allowing me to use the SMTP server, I had to log in into my Gmail account and under this link https://www.google.com/settings/security set the "Access for less secure apps" to "Enabled". Then finally it did work!!

Anonymous classes always extend superclass or implements interfaces. for example:

button.addActionListener(new ActionListener(){ // ActionListener is an interface
    public void actionPerformed(ActionEvent e){
    }
});

Moreover, although anonymous class cannot implement multiple interfaces, you can create an interface that extends other interface and let your anonymous class to implement it.

Add one unique session or cookie in button click event then redirect page on same URL using Request.RawUrl Now add code in Page_Load event to grab that session or coockie. If session/cookie matches then you can knows that page redirected using refresh button. So decrease hit counter by 1 to keep it on same number do hitcountr -= hitconter

Else increase the hit counter.

final

final can be used to mark a variable "unchangeable"

private final String name = "foo";  //the reference name can never change

final can also make a method not "overrideable"

public final String toString() {  return "NULL"; }

final can also make a class not "inheritable". i.e. the class can not be subclassed.

public final class finalClass {...}
public class classNotAllowed extends finalClass {...} // Not allowed

finally

finally is used in a try/catch statement to execute code "always"

lock.lock();
try {
  //do stuff
} catch (SomeException se) {
  //handle se
} finally {
  lock.unlock(); //always executed, even if Exception or Error or se
}

Java 7 has a new try with resources statement that you can use to automatically close resources that explicitly or implicitly implement java.io.Closeable or java.lang.AutoCloseable

finalize

finalize is called when an object is garbage collected. You rarely need to override it. An example:

protected void finalize() {
  //free resources (e.g. unallocate memory)
  super.finalize();
}

Yes, this is possible and I would like to provide a slight alternative to Rajeev's answer that does not pass a php-generated datetime formatted string to the query.

The important distinction about how to declare the values to be SET in the UPDATE query is that they must not be quoted as literal strings.

To prevent CodeIgniter from doing this "favor" automatically, use the set() method with a third parameter of false.

$userId = 444;
$this->db->set('Last', 'Current', false);
$this->db->set('Current', 'NOW()', false);
$this->db->where('Id', $userId);
// return $this->db->get_compiled_update('Login');  // uncomment to see the rendered query
$this->db->update('Login');
return $this->db->affected_rows();  // this is expected to return the integer: 1

The generated query (depending on your database adapter) would be like this:

UPDATE `Login` SET Last = Current, Current = NOW() WHERE `Id` = 444

Demonstrated proof that the query works: https://www.db-fiddle.com/f/vcc6PfMcYhDD87wZE5gBtw/0

In this case, Last and Current ARE MySQL Keywords, but they are not Reserved Keywords, so they don't need to be backtick-wrapped.

If your precise query needs to have properly quoted identifiers (table/column names), then there is always protectIdentifiers().
