We created a new 'runserver' management command which is a thin wrapper around the standard one but changes the default port. Roughly, you create management/commands/runserver.py and put in something like this:

# Override the value of the constant coded into django...
import django.core.management.commands.runserver as runserver
runserver.DEFAULT_PORT="8001"

# ...print out a warning...
# (This gets output twice because runserver fires up two threads (one for autoreload).
#  We're living with it for now :-)
import os
dir_path = os.path.splitext(os.path.relpath(__file__))[0]
python_path = dir_path.replace(os.sep, ".")
print "Using %s with default port %s" % (python_path, runserver.DEFAULT_PORT)

# ...and then just import its standard Command class.
# Then manage.py runserver behaves normally in all other regards.
from django.core.management.commands.runserver import Command

If you want to concatenate multiple columns which itself have 4000 bytes, then you can concatenate the XMLAGG output of each column to avoid the SQL limit of 4000 bytes.

For example,

WITH DATA AS
  ( SELECT 1 id, rpad('a1',4000,'*') col1, rpad('b1',4000,'*') col2 FROM dual
  UNION
  SELECT 2 id, rpad('a2',4000,'*') col1, rpad('b2',4000,'*') col2 FROM dual
  )
SELECT ID,
       rtrim(xmlagg(XMLELEMENT(e,col1,',').EXTRACT('//text()') ).GetClobVal(), ',')
       || 
       rtrim(xmlagg(XMLELEMENT(e,col2,',').EXTRACT('//text()') ).GetClobVal(), ',') 
       AS very_long_text
FROM DATA
GROUP BY ID
ORDER BY ID;

Simplest solution

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

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

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

Other Solutions

Also know there are other options:

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

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

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

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

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

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

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

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

Rarer options for edge cases

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

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

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

Example:

$test = "chees";
"${test}y";

It will output:

cheesy

It is exactly what you are looking for.

I have converted to using Powershell calls for this purpose in my scripts. It requires script execution permission and is by far the slowest option. However it is also localization independent, very easy to write and read, and it is much more feasible to perform adjustments to the date like addition/subtraction or get the last day of the month, etc.

Here is how to get the day, month, and year

for /f %%i in ('"powershell (Get-Date).ToString(\"dd\")"') do set day=%%i
for /f %%i in ('"powershell (Get-Date).ToString(\"MM\")"') do set month=%%i
for /f %%i in ('"powershell (Get-Date).ToString(\"yyyy\")"') do set year=%%i

Or, here is yesterday's date in yyyy-MM-dd format

for /f %%i in ('"powershell (Get-Date).AddDays(-1).ToString(\"yyyy-MM-dd\")"') do set yesterday=%%i

Day of the week

for /f %%d in ('"powershell (Get-Date).DayOfWeek"') do set DayOfWeek=%%d

Current time plus 15 minutes

for /f %%i in ('"powershell (Get-Date).AddMinutes(15).ToString(\"HH:mm\")"') do set time=%%i

Try this:

item.shipping!==undefined

FWIW, this config worked for me:

location = /logpush.html {
  if ($request_method = POST) {
    access_log /var/log/nginx/push.log push_requests;
    proxy_pass $scheme://127.0.0.1/logsink;
    break;
  }   
  return 200 $scheme://$host/serviceup.html;
}   
#
location /logsink {
  return 200;
}

For me, it was because I ran

$ phpunit .

instead of

$ phpunit

when I already had a configured phpunit.xml file in the working directory.

Your code and schema are OK. You probably trying on previous version of table.

http://sqlfiddle.com/#!2/9dc64/1/0

Your table even has no UNIQUE, so that error is impossible on that table.

Backup data from that table, drop it and re-create.

Maybe you tried to run that CREATE TABLE IF NOT EXIST. It was not created, you have old version, but there was no error because of IF NOT EXIST.

You may run SQL like this to see current table structure:

DESCRIBE my_table;

Edit - added later:

Try to run this:

DROP TABLE `my_table`; --make backup - it deletes table

CREATE TABLE `my_table` (
  `number` int(11) NOT NULL,
  `name` varchar(50) NOT NULL,
  `money` int(11) NOT NULL,
  PRIMARY KEY (`number`,`name`),
  UNIQUE (`number`, `name`) --added unique on 2 rows
) ENGINE=MyISAM;

Because a stateless protocol does not require the server to retain session information or status about each communications partner for the duration of multiple requests.

HTTP is a stateless protocol, which means that the connection between the browser and the server is lost once the transaction ends.

You could have switch construct "handle" ranges by using it in conjunction with a List of your bounds.

List<int> bounds = new List<int>() {int.MinValue, 0, 4, 9, 17, 20, int.MaxValue };

switch (bounds.IndexOf(bounds.Last(x => x < j)))
{
    case 0: // <=0
        break;

    case 1: // >= 1 and <=4
        break;
    case 2: // >= 5 and <=9
        break;
    case 3: // >= 10 and <=17
        break;
    case 4: // >= 18 and <=20
        break;

    case 5: // >20
        break;
}

With this approach ranges can have different spans.

It is documented in jQuery API Documentation. Check for Internet Explorer with $.browser.msie and then check its version with $.browser.version.

UPDATE: $.browser removed in jQuery 1.9

The jQuery.browser() method has been deprecated since jQuery 1.3 and is removed in 1.9. If needed, it is available as part of the jQuery Migrate plugin. We recommend using feature detection with a library such as Modernizr.

It's not related to Ken's case directly, but such an error also can occur if you copied .h file and forgot to change #ifndef directive. In this case compiler will just skip definition of the class thinking that it's a duplication.

Edit:

This removes html code or php if you supplement it. Allows you to add trailing slash and it come up as well as the url without the trailing slash all bypassing the 404 code. Plus a little added security.

The message is actually pretty clear: something creates a ThreadLocal with value of type org.apache.axis.MessageContext - this is a great hint. It most likely means that Apache Axis framework forgot/failed to cleanup after itself. The same problem occurred for instance in Logback. You shouldn't bother much, but reporting a bug to Axis team might be a good idea.

Tomcat reports this error because the ThreadLocals are created per HTTP worker threads. Your application is undeployed but HTTP threads remain - and these ThreadLocals as well. This may lead to memory leaks (org.apache.axis.MessageContext can't be unloaded) and some issues when these threads are reused in the future.

For details see: http://wiki.apache.org/tomcat/MemoryLeakProtection

In general, you can use a backslash at the end of a line in order for the command to continue on to the next line. However, there are cases where commands are implicitly continued, namely when the line ends with a token than cannot legally terminate a command. In that case, the shell knows that more is coming, and the backslash can be omitted. Some examples:

# In general
$ echo "foo" \
> "bar"
foo bar

# Pipes
$ echo foo |
> cat
foo

# && and ||
$ echo foo &&
> echo bar
foo
bar
$ false ||
> echo bar
bar

Different, but related, is the implicit continuation inside quotes. In this case, without a backslash, you are simply adding a newline to the string.

$ x="foo
> bar"
$ echo "$x"
foo
bar

With a backslash, you are again splitting the logical line into multiple logical lines.

$ x="foo\
> bar"
$ echo "$x"
foobar

You can use x.astype('uint8') where x is your Boolean array.

@Tim's answer only does half the work -- that gets it into a datetime.datetime object.

To get it into the string format you require, you use datetime.strftime:

print(datetime.strftime('%b %d,%Y'))

You can easily get child itself and all of its decedents (children) with Jquery's Clone() method, just

var child = $('#div div:nth-child(1)').clone();  

var child2 = $('#div div:nth-child(2)').clone();

You will get this for first query as asked in question

<div id="div1">
     <p>Some Content</p>
</div>

This answer could be really late, but its useful.

You can play youtube videos in the app itself using android-youtube-player.

Some code snippets:

To play a youtube video that has a video id in the url, you simply call the OpenYouTubePlayerActivity intent

Intent intent = new Intent(null, Uri.parse("ytv://"+v), this, 
            OpenYouTubePlayerActivity.class);
startActivity(intent);

where v is the video id.

Add the following permissions in the manifest file:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

and also declare this activity in the manifest file:

<activity 
        android:name="com.keyes.youtube.OpenYouTubePlayerActivity"></activity>

Further information can be obtained from the first portions of this code file.

Hope that helps anyone!

To choose a different location or file type (e.g. PNG or SVG) for the favicon:
One reason can be that you want to have the icon in a specific location, perhaps in the images folder or something alike. For example:

<link rel="icon" href="_/img/favicon.png">

This diferent location may even be a CDN, just like SO seems to do with <link rel="shortcut icon" href="http://cdn.sstatic.net/stackoverflow/img/favicon.ico">.

To learn more about using other file types like PNG check out this question.

For cache busting purposes:
Add a query string to the path for cache-busting purposes:

<link rel="icon" href="/favicon.ico?v=1.1"> 

Favicons are very heavily cached and this a great way to ensure a refresh.

Footnote about default location:
As far as the first bit of the question: all modern browsers would detect a favicon at the default location, so that's not a reason to use a link for it.

Footnote about rel="icon":
As indicated by @Semanino's answer, using rel="shortcut icon" is an old technique which was required by older versions of Internet Explorer, but in most cases can be replaced by the more correct rel="icon" instruction. The article @Semanino based this on properly links to the appropriate spec which shows a rel value of shortcut isn't a valid option.

Getting cuDNN Version [Linux]

Use following to find path for cuDNN:

cat $(whereis cudnn.h) | grep CUDNN_MAJOR -A 2

If above doesn't work try this:

cat $(whereis cuda)/include/cudnn.h | grep CUDNN_MAJOR -A 2

Getting cuDNN Version [Windows]

Use following to find path for cuDNN:

C:\>where cudnn*
C:\Program Files\cuDNN6\cuda\bin\cudnn64_6.dll

Then use this to dump version from header file,

type "%PROGRAMFILES%\cuDNN6\cuda\include\cudnn.h" | findstr "CUDNN_MAJOR CUDNN_MINOR CUDNN_PATCHLEVEL"

Getting CUDA Version

This works on Linux as well as Windows:

nvcc --version

Put simply

• & means the address-of, you will see that in placeholders for functions to modify the parameter variable as in C, parameter variables are passed by value, using the ampersand means to pass by reference.
• * means the dereference of a pointer variable, meaning to get the value of that pointer variable.

int foo(int *x){
   *x++;
}

int main(int argc, char **argv){
   int y = 5;
   foo(&y);  // Now y is incremented and in scope here
   printf("value of y = %d\n", y); // output is 6
   /* ... */
}

The above example illustrates how to call a function foo by using pass-by-reference, compare with this

int foo(int x){
   x++;
}

int main(int argc, char **argv){
   int y = 5;
   foo(y);  // Now y is still 5
   printf("value of y = %d\n", y); // output is 5
   /* ... */
}

Here's an illustration of using a dereference

int main(int argc, char **argv){
   int y = 5;
   int *p = NULL;
   p = &y;
   printf("value of *p = %d\n", *p); // output is 5
}

The above illustrates how we got the address-of y and assigned it to the pointer variable p. Then we dereference p by attaching the * to the front of it to obtain the value of p, i.e. *p.

session.query().with_entities(SomeModel.col1)

is the same as

session.query(SomeModel.col1)

for alias, we can use .label()

session.query(SomeModel.col1.label('some alias name'))

You can do (jQuery 1.6 onwards):

$('#idCheckbox').prop('checked', true);
$('#idCheckbox').prop('checked', false);

to remove you can also use:

$('#idCheckbox').removeProp('checked');

with jQuery < 1.6 you must do

$('#idCheckbox').attr('checked', true);
$('#idCheckbox').removeAttr('checked');

Here is a way to center content both vertically and horizontally in any situation, which is useful when you do not know the width or height or both:

CSS

#container {
    display: table;
    width: 300px; /* not required, just for example */
    height: 400px; /* not required, just for example */
}

#update {
    display: table-cell;
    vertical-align: middle;
    text-align: center;
}

HTML

<div id="container">
    <a id="update" href="#">
        <i class="icon-refresh"></i>
    </a>
</div>

JSFiddle

Note that the width and height values are just for demonstration here, you can change them to anything you want (or remove them entirely) and it will still work because the vertical centering here is a product of the way the table-cell display property works.

I doubt it but maybe running svn cleanup on your working directory will help.

To update a subset of fields, you can use update_fields:

survey.save(update_fields=["active"]) 

The update_fields argument was added in Django 1.5. In earlier versions, you could use the update() method instead:

Survey.objects.filter(pk=survey.pk).update(active=True)

UTF-16 and UTF-8 are both encodings of Unicode. They are both Unicode; one is not more Unicode than the other.

Don't let an unfortunate historical artifact from Microsoft confuse you.

To complete the other answers: If you are using C++11, use nullptr, which is a keyword that means a void pointer pointing to null. (instead of NULL, which is not a pointer type)

Here's an example previously found at androidsnippets.com (the site is currently not maintained anymore).

// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php");

try {
    // Add your data
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
    nameValuePairs.add(new BasicNameValuePair("id", "12345"));
    nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

    // Execute HTTP Post Request
    HttpResponse response = httpclient.execute(httppost);

} catch (ClientProtocolException e) {
    // TODO Auto-generated catch block
} catch (IOException e) {
    // TODO Auto-generated catch block
}

So, you can add your parameters as BasicNameValuePair.

An alternative is to use (Http)URLConnection. See also Using java.net.URLConnection to fire and handle HTTP requests. This is actually the preferred method in newer Android versions (Gingerbread+). See also this blog, this developer doc and Android's HttpURLConnection javadoc.

Sorry for replying on an older question, but I would like to clarify the last question.

You use a "get" method for your form. When the name of your input-field is "g", it will make a URL like this:

https://www.google.com/search?g=[value from input-field]

But when you search with google, you notice the following URL:

https://www.google.nl/search?q=google+search+bar

Google uses the "q" Querystring variable as it's search-query. Therefor, renaming your field from "g" to "q" solved the problem.

In regards to the first comment: If you do this you will get an error(in Android Studio). This is in regards to it being out of the Android namespace. If you don't know how to fix this error, check the example out below. Hope this helps!

Example -Before :

<string-array name="roomSize">
    <item>Small(0-4)</item>
    <item>Medium(4-8)</item>
    <item>Large(9+)</item>
</string-array>

Example - After:

<string-array android:name="roomSize">
    <item>Small(0-4)</item>
    <item>Medium(4-8)</item>
    <item>Large(9+)</item>
</string-array>

Try to put android:gravity="center_vertical|right" inside parent LinearLayout else as you are inside RelativeLayout you can put android:layout_centerInParent="true" inside your scrollView.

Check out the DirectoryIterator class.

    if($fileInfo->isDot()) continue;
    echo $fileInfo->getFilename() . "<br>\n";
}

The recursive version is RecursiveDirectoryIterator.

What about this approach:

I was actually wondering how to do this today...and coincidentally, Phil Haack posted a tip about using posh-git (Git on powershell), which gives you tab auto-complete and a few more cool bits. I'm not going back to Git bash.

check it out

http://haacked.com/archive/2011/12/13/better-git-with-powershell.aspx

Use this instead:

$('#save').click(function () {
    $('#mytable').find('input[type="checkbox"]:checked') //...
});

Let me explain you what the selector does: input[type="checkbox"] means that this will match each <input /> with type attribute type equals to checkbox After that: :checked will match all checked checkboxes.

You can loop over these checkboxes with:

$('#save').click(function () {
    $('#mytable').find('input[type="checkbox"]:checked').each(function () {
       //this is the current checkbox
    });
});

Here is demo in JSFiddle.

And here is a demo which solves exactly your problem http://jsfiddle.net/DuE8K/1/.

$('#save').click(function () {
    $('#mytable').find('tr').each(function () {
        var row = $(this);
        if (row.find('input[type="checkbox"]').is(':checked') &&
            row.find('textarea').val().length <= 0) {
            alert('You must fill the text area!');
        }
    });
});

read from assets html file

ViewGroup webGroup;
  String content = readContent("content/ganji.html");

        final WebView webView = new WebView(this);
        webView.loadDataWithBaseURL(null, content, "text/html", "UTF-8", null);

        webGroup.addView(webView);

First, make a display: block of your table

then, set overflow-x: to auto.

table {
    display: block;
    overflow-x: auto;
    white-space: nowrap;
}

Nice and clean. No superfluous formatting.

Here are more involved examples with scrolling table captions from a page on my website.

If an issue is taken about cells not filling the entire table, append the following additional CSS code:

table tbody {
    display: table;
    width: 100%;
}

var tilllastbackslashregex = new RegExp(/^.*\//);
baseUrl = tilllastbackslashregex.exec(window.location.href);

window.location.href gives the current url address from browser address bar

it can be any thing like https://stackoverflow.com/abc/xyz or https://www.google.com/search?q=abc tilllastbackslashregex.exec() run regex and retun the matched string till last backslash ie https://stackoverflow.com/abc/ or https://www.google.com/ respectively

You can load HTML page partial, in your case is everything inside div#mytable.

setTimeout(function(){
   $( "#mytable" ).load( "your-current-page.html #mytable" );
}, 2000); //refresh every 2 seconds

more information read this http://api.jquery.com/load/

Update Code (if you don't want it auto-refresh)

<button id="refresh-btn">Refresh Table</button>

<script>
$(document).ready(function() {

   function RefreshTable() {
       $( "#mytable" ).load( "your-current-page.html #mytable" );
   }

   $("#refresh-btn").on("click", RefreshTable);

   // OR CAN THIS WAY
   //
   // $("#refresh-btn").on("click", function() {
   //    $( "#mytable" ).load( "your-current-page.html #mytable" );
   // });


});
</script>

Try this instead:

  =SUM(IF(MONTH($A$2:$A$6)=1,$B$2:$B$6,0))

It's an array formula, so you will need to enter it with the Control-Shift-Enter key combination.

Here's how the formula works.

1. MONTH($A$2:$A$6) creates an array of numeric values of the month for the dates in A2:A6, that is,
   {1, 1, 1, 2, 2}.
2. Then the comparison {1, 1, 1, 2, 2}= 1 produces the array {TRUE, TRUE, TRUE, FALSE, FALSE}, which comprises the condition for the IF statement.
3. The IF statement then returns an array of values, with {430, 96, 400.. for the values of the sum ranges where the month value equals 1 and ..0,0} where the month value does not equal 1.
4. That array {430, 96, 400, 0, 0} is then summed to get the answer you are looking for.

This is essentially equivalent to what the SUMIF and SUMIFs functions do. However, neither of those functions support the kind of calculation you tried to include in the conditional.

It's also possible to drop the IF completely. Since TRUE and FALSE can also be treated as 1 and 0, this formula--=SUM((MONTH($A$2:$A$6)=1)*$B$2:$B$6)--also works.

Heads up: This does not work in Google Spreadsheets

You cannot do that in all browsers, supposedly IE does allow it, but Mozilla and Opera do not.

When you compose a message in GMail, the 'attach files' feature is implemented one way for IE and any browser that supports this, and then implemented another way for Firefox and those browsers that do not.

I don't know why you cannot do it, but one thing that is a security risk, and which you are not allowed to do in any browser, is programmatically set the file name on the HTML File element.

The bottom of the javadoc for the java.util package contains some good links:

• Collections Overview has a nice summary table.
• Annotated Outline lists all of the implementations on one page.

From the manual:

Possible values for the parameter timeout: … x set timeout to x seconds

and

readlines(sizehint=None, eol='\n') Read a list of lines, until timeout. sizehint is ignored and only present for API compatibility with built-in File objects.

Note that this function only returns on a timeout.

So your readlines will return at most every 2 seconds. Use read() as Tim suggested.

My return object didn't have @XmlRootElement annotation on the class. Adding the annotation solved my issue.

@XmlRootElement(name = "ReturnObjectClass")
public class ReturnObjectClass {

    @XmlElement(name = "Status", required = true)
    protected StatusType status;
    //...
}

Anonymous inner classes are effectively closures, so they can be used to emulate lambda expressions or "delegates". For example, take this interface:

public interface F<A, B> {
   B f(A a);
}

You can use this anonymously to create a first-class function in Java. Let's say you have the following method that returns the first number larger than i in the given list, or i if no number is larger:

public static int larger(final List<Integer> ns, final int i) {
  for (Integer n : ns)
     if (n > i)
        return n;
  return i;
}

And then you have another method that returns the first number smaller than i in the given list, or i if no number is smaller:

public static int smaller(final List<Integer> ns, final int i) {
   for (Integer n : ns)
      if (n < i)
         return n;
   return i;
}

These methods are almost identical. Using the first-class function type F, we can rewrite these into one method as follows:

public static <T> T firstMatch(final List<T> ts, final F<T, Boolean> f, T z) {
   for (T t : ts)
      if (f.f(t))
         return t;
   return z;
}

You can use an anonymous class to use the firstMatch method:

F<Integer, Boolean> greaterThanTen = new F<Integer, Boolean> {
   Boolean f(final Integer n) {
      return n > 10;
   }
};
int moreThanMyFingersCanCount = firstMatch(xs, greaterThanTen, x);

This is a really contrived example, but its easy to see that being able to pass functions around as if they were values is a pretty useful feature. See "Can Your Programming Language Do This" by Joel himself.

A nice library for programming Java in this style: Functional Java.

Iterating over a dictionary object itself actually gives you an iterator over its keys. Python is trying to unpack keys, which you get from m.type + m.purity into (m, k).

My crystal ball says m.type and m.purity are both strings, so your keys are also strings. Strings are iterable, so they can be unpacked; but iterating over the string gives you an iterator over its characters. So whenever m.type + m.purity is more than two characters long, you have too many values to unpack. (And whenever it's shorter, you have too few values to unpack.)

To fix this, you can iterate explicitly over the items of the dict, which are the (key, value) pairs that you seem to be expecting. But if you only want the values, then just use the values.

(In 2.x, itervalues, iterkeys, and iteritems are typically a better idea; the non-iter versions create a new list object containing the values/keys/items. For large dictionaries and trivial tasks within the iteration, this can be a lot slower than the iter versions which just set up an iterator.)

Here's a solution using a negative lookahead (not supported in all regex engines):

^[a-zA-Z](((?!__)[a-zA-Z0-9_])*[a-zA-Z0-9])?$

Test that it works as expected:

import re
tests = [
   ('a', True),
   ('_', False),
   ('zz', True),
   ('a0', True),
   ('A_', False),
   ('a0_b', True),
   ('a__b', False),
   ('a_1_c', True),
]

regex = '^[a-zA-Z](((?!__)[a-zA-Z0-9_])*[a-zA-Z0-9])?$'
for test in tests:
   is_match = re.match(regex, test[0]) is not None
   if is_match != test[1]:
       print "fail: "  + test[0]

Jquery code which contains simple ajax :

   $("#product").on("input", function(event) {
      var data=$("#nameform").serialize();
    $.post("./__partails/search-productbyCat.php",data,function(e){
       $(".result").empty().append(e);

     });


    });

Html elements you can use any element:

     <form id="nameform">
     <input type="text" name="product" id="product">
     </form>

php Code:

  $pdo=new PDO("mysql:host=localhost;dbname=onlineshooping","root","");
  $Catagoryf=$_POST['product'];

 $pricef=$_POST['price'];
  $colorf=$_POST['color'];

  $stmtcat=$pdo->prepare('SELECT * from products where Catagory =?');
  $stmtcat->execute(array($Catagoryf));

  while($result=$stmtcat->fetch(PDO::FETCH_ASSOC)){
  $iddb=$result['ID'];
     $namedb=$result['Name'];
    $pricedb=$result['Price'];
     $colordb=$result['Color'];

   echo "<tr>";
   echo "<td><a href=./pages/productsinfo.php?id=".$iddb."> $namedb</a> </td>".'<br>'; 
   echo "<td><pre>$pricedb</pre></td>";
   echo "<td><pre>    $colordb</pre>";
   echo "</tr>";

The easy way

For your example query, the only possible value greater than 2 and less than 4 is 3, so we simplify:

GROUP BY meetingID
HAVING COUNT(caseID) = 3

In your general case:

GROUP BY meetingID
HAVING COUNT(caseID) > x AND COUNT(caseID) < 7

Or (possibly easier to read?),

GROUP BY meetingID
HAVING COUNT(caseID) BETWEEN x+1 AND 6

I believe DI is a type of abstraction layer on factories, but they also provide benefits beyond abstraction. A true factory knows how to instantiate a single type and configure it. A good DI layer provides the ability, through configuration, to instantiate and configure many types.

Obviously, for a project with a few simple types that requires relatively stable business logic in their construction, the factory pattern is simple to understand, implement, and works well.

OTOH, if you have a project containing numerous types whose implementations you expect to change often, DI gives you the flexibility through its configuration to do this at runtime without having to recompile your factories.

C arrays are not one of the supported data types for properties. See "The Objective-C Programming Language" in Xcode documentation, in the Declared Properties page:

Supported Types

You can declare a property for any Objective-C class, Core Foundation data type, or “plain old data” (POD) type (see C++ Language Note: POD Types). For constraints on using Core Foundation types, however, see “Core Foundation.”

POD does not include C arrays. See http://www.fnal.gov/docs/working-groups/fpcltf/Pkg/ISOcxx/doc/POD.html

If you need an array, you should use NSArray or NSData.

The workarounds, as I see it, are like using (void *) to circumvent type checking. You can do it, but it makes your code less maintainable.

Here is the crisp answer:

public String sendSMS(String phone, String token) {
    WebClient webClient = WebClient.create(smsServiceUrl);

    SMSRequest smsRequest = new SMSRequest();
    smsRequest.setMessage(token);
    smsRequest.setPhoneNo(phone);
    smsRequest.setTokenId(smsServiceTokenId);

    Mono<String> response = webClient.post()
          .uri(smsServiceEndpoint)
          .header(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE)
          .body(Mono.just(smsRequest), SMSRequest.class)
          .retrieve().bodyToMono(String.class);

    String deliveryResponse = response.block();
    if (deliveryResponse.equalsIgnoreCase("success")) {
      return deliveryResponse;
    }
    return null;
}

Look at ~/.myslgui/query-browser/history.xml here you can find the last queries made with mysql_query_browser (some days old)

A more general solution could be a extension

extension String {
    var toFloat:Float {
        return Float(self.bridgeToObjectiveC().floatValue)
    }
    var toDouble:Double {
        ....
    }
    ....
}

this for example extends the swift native String object by toFloat

If you use script to navigate to the page, use the open method with the target _blank to open a new window / tab:

<img src="..." alt="..." onclick="window.open('anotherpage.html', '_blank');" />

However, if you want search engines to find the page, you should just wrap the image in a regular link instead.

Don't forget to update your iptables firewall if you have one to allow the 20-21 and 1024-1048 ranges in.

Do this from /etc/sysconfig/iptables

Adding lines like this:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 20:21 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 1024:1048 -j ACCEPT

And restart iptables with the command:

sudo service iptables restart

If your database client connects with TCP/IP and you have ident auth configured in your pg_hba.conf check that you have an identd installed and running. This is mandatory even if you have only local clients connecting to "localhost".

Also beware that nowadays the identd may have to be IPv6 enabled for Postgresql to welcome clients which connect to localhost.

Dll v/s Exe

1)DLL file is a dynamic link library which can be used in exe files and other dll files.
EXE file is a executable file which runs in a separate process which is managed by OS.

2)DLLs are not directly executable . They are separate files containing functions that can be called by programs and other DLLs to perform computations and functions.
An EXE is a program that can be executed . Ex :Windows program

3)Reusability
DLL: They can be reused for some other application. As long as the coder knows the names and parameters of the functions and procedures in the DLL file .
EXE: Only for specific purpose .

4)A DLL would share the same process and memory space of the calling application while an
EXE creates its separate process and memory space.

5)Uses
DLL: You want many applications to use it but you don't want to give them the source code You can't copy-paste the code for the button in every program, so you decide you want to create a DL-Library (DLL).

EXE: When we work with project templates like Windows Forms Applications, Console Applications, WPF Applications and Windows Services they generate an exe assembly when compiled.

6)Similarities :
Both DLL and EXE are binary files have a complex nested structure defined by the Portable Executable format, and they are not intended to be editable by users.

In case you don't want to use the M2_HOME and want to direct the IntelliJ to the maven installation you can simply set it by:

• goto File => Setting => Maven => Maven home directory
• point to your maven build directory e.g. /usr/local/maven/apache-maven-3.0.4

A better way is to have a symlink e.g. 'latest' for the latest version and point your IntelliJ to use that for consistency, given latest points to the latest version of maven installed on your box.

Use this way so that result will not be displayed while running stored procedure.

The query:

SELECT a.strUserID FROM tblUsers a WHERE a.lngUserID = lngUserID LIMIT 1 INTO @strUserID;

Please use the attributes from the System.Web.Http namespace on your WebAPI actions:

    [System.Web.Http.AcceptVerbs("GET", "POST")]
    [System.Web.Http.HttpGet]
    public string Auth(string username, string password)
    {...}

The reason why it doesn't work is because you were using the attributes that are from the MVC namespace System.Web.Mvc. The classes in the System.Web.Http namespace are for WebAPI.

You can disable FK and CHECK constraints only in SQL 2005+. See ALTER TABLE

ALTER TABLE foo NOCHECK CONSTRAINT ALL

or

ALTER TABLE foo NOCHECK CONSTRAINT CK_foo_column

Primary keys and unique constraints can not be disabled, but this should be OK if I've understood you correctly.

if you are using Spring version of 3.1 or newer you can specify "produces" in @RequestMapping annotation. Example below works for me out of box. No need of register converter or anything else if you have web mvc enabled (@EnableWebMvc).

@ResponseBody
@RequestMapping(value = "/photo2", method = RequestMethod.GET, produces = MediaType.IMAGE_JPEG_VALUE)
public byte[] testphoto() throws IOException {
    InputStream in = servletContext.getResourceAsStream("/images/no_image.jpg");
    return IOUtils.toByteArray(in);
}

If you want to inspect html, css or maybe you need js console in your mobile browser . You can use excelent tool eruda Using it you have the same Developer Tools on your mobile browser like in your desctop device. Dont forget to upvote :) Here is a link https://github.com/liriliri/eruda

 select

           when len('3601')=6   then c.blkcd  
           when len('3601')=11  then c.schcd   end = '3601'

Change your maximum size,

label1.MaximumSize = new Size(100, 0);

And set your autosize to true.

label1.AutoSize = true;

That's it!

Can you set the ActionBar before you set the Contient View? This order would be better:

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

    ActionBar actionBar =getSupportActionBar();
    actionBar.setDisplayHomeAsUpEnabled(true);            
  }

To add to answer given by Anil, In symfony3, you can use $this->getUser() to determine if the user is logged in, a simple condition like if(!$this->getUser()) {} will do.

If you look at the source code which is available in base controller, it does the exact same thing defined by Anil.

<%= link_to root_path do %><%= image_tag("Search.png",:alt=>'Vivek',:title=>'Vivek',:class=>'dock-item')%><%= content_tag(:span, "Search").html_safe%><% end %>

Will appreciate any remarks. maybe someone can use it sometime.

It is recommended to check default terminal shell before set JAVA_HOME environment variable, via following commands:

$ echo $SHELL
/bin/bash

If your default terminal is /bin/bash (Bash), then you should use @hygull method

If your default terminal is /bin/zsh (Z Shell), then you should set these environment variable in ~/.zshenv file with following contents:

export JAVA_HOME="$(/usr/libexec/java_home)"

Similarly, any other terminal type not mentioned above, you should set environment variable in its respective terminal env file.

This method tested working in macOS Mojave Version 10.14.6.

Wouldn't setting a css rule for all tables, and then a subsequent one for tables where class="dojoxGrid" work? Or am I missing something?

Solution by Mosh Hamedani

Creating a StopWatch function constructor.

Define 4 local variables

1. startTime
2. endTime
3. isRunning
4. duration set to 0

Next create 3 methods

1. start
2. stop
3. reset

start method

• check if isRunning is true if so throw an error that start cannot be called twice.
• set isRunning to true
• assign the current Date object to startTime.

stop method

• check if isRunning is false if so throw an error that stop cannot be called twice.
• set isRunning to false
• assign the current Date object to endTime.
• calculate the seconds by endTime and startTime Date object
• increment duration with seconds

reset method:

• reset all the local variables.

Read-only property

if you want to access the duration local variable you need to define a property using Object.defineProperty. It's useful when you want to create a read-only property.

Object.defineProperty takes 3 parameters

• the object which to define a property (in this case the current object (this))
• the name of the property

• the value of the key property.

• We want to create a Read-only property so we pass an object as a value. The object contain a get method that return the duration local variable. in this way we cannot change the property only get it.

The trick is to use Date() object to calculate the time.

Reference the code below

function StopWatch() {


let startTime,
    endTime,
    isRunning,
    duration = 0;

  this.start = function () {
    if (isRunning) throw new Error("StopWatch has already been started.");

    isRunning = true;

    startTime = new Date();
  };



this.stop = function () {
    if (!isRunning) throw new Error("StopWatch has already been stop.");

    isRunning = false;

    endTime = new Date();

    const seconds = (endTime.getTime() - startTime.getTime()) / 1000;
    duration += seconds;
  };

  this.reset = function () {
    duration = 0;
    startTime = null;
    endTime = null;
    isRunning = false;
  };

  Object.defineProperty(this, "duration", {
    get: function () {
      return duration;
    },
  });
}

const sw = new StopWatch();

With CLI in one line :

mysql --user=root --password=pass --host=localhost db_name --execute='select version()';

or

mysql -uroot -ppass -hlocalhost db_name -e 'select version()';

return something like this :

+-----------+
| version() |
+-----------+

Using rcParams you can show grid very easily as follows

plt.rcParams['axes.facecolor'] = 'white'
plt.rcParams['axes.edgecolor'] = 'white'
plt.rcParams['axes.grid'] = True
plt.rcParams['grid.alpha'] = 1
plt.rcParams['grid.color'] = "#cccccc"

If grid is not showing even after changing these parameters then use

plt.grid(True)

before calling

plt.show()

See this:

In the Microsoft .NET framework, an assembly is a partially compiled code library for use in deployment, versioning and security

It was suggested to post this as an answer, because some other answers are giving errors like 'The name Context does not exist in the current context'.

Just using the following works:

Request.Query["queryparm1"]

Sample usage:

<a href="@Url.Action("Query",new {parm1=Request.Query["queryparm1"]})">GO</a>

The effect you want is to treat the NULL as the largest possible date then replace it with NULL again upon completion:

SELECT RecordId, MIN(StartDate), NULLIF(MAX(COALESCE(EndDate,'9999-12-31')),'9999-12-31') 
  FROM tmp GROUP BY RecordId

Per your fiddle this will return the exact results you specify under all conditions.

The second one:

word.contains("\n");

Well, I am a bit curious, so I just tested the three myself right after asking the question ;-)

Ok, this is not a very serious review, but here is what I can say:

I tried the tools with the default settings (it's important because you can pretty much choose your check rules) on the following script:

#!/usr/local/bin/python
# by Daniel Rosengren modified by e-satis

import sys, time
stdout = sys.stdout

BAILOUT = 16
MAX_ITERATIONS = 1000

class Iterator(object) :

    def __init__(self):

        print 'Rendering...'
        for y in xrange(-39, 39):
            stdout.write('\n')
            for x in xrange(-39, 39):
                if self.mandelbrot(x/40.0, y/40.0) :
                    stdout.write(' ')
                else:
                    stdout.write('*')


    def mandelbrot(self, x, y):
        cr = y - 0.5
        ci = x
        zi = 0.0
        zr = 0.0

        for i in xrange(MAX_ITERATIONS) :
            temp = zr * zi
            zr2 = zr * zr
            zi2 = zi * zi
            zr = zr2 - zi2 + cr
            zi = temp + temp + ci

            if zi2 + zr2 > BAILOUT:
                return i

        return 0

t = time.time()
Iterator()
print '\nPython Elapsed %.02f' % (time.time() - t)

As a result:

• PyChecker is troublesome because it compiles the module to analyze it. If you don't want your code to run (e.g, it performs a SQL query), that's bad.
• PyFlakes is supposed to be light. Indeed, it decided that the code was perfect. I am looking for something quite severe so I don't think I'll go for it.
• PyLint has been very talkative and rated the code 3/10 (OMG, I'm a dirty coder !).

Strong points of PyLint:

• Very descriptive and accurate report.
• Detect some code smells. Here it told me to drop my class to write something with functions because the OO approach was useless in this specific case. Something I knew, but never expected a computer to tell me :-p
• The fully corrected code run faster (no class, no reference binding...).
• Made by a French team. OK, it's not a plus for everybody, but I like it ;-)

Cons of Pylint:

• Some rules are really strict. I know that you can change it and that the default is to match PEP8, but is it such a crime to write 'for x in seq'? Apparently yes because you can't write a variable name with less than 3 letters. I will change that.
• Very very talkative. Be ready to use your eyes.

Thanks to Rudiger Wolf, I discovered pep8 that does exactly what its name suggests: matching PEP8. It has found several syntax no-nos that Pylint did not. But Pylint found stuff that was not specifically linked to PEP8 but interesting. Both tools are interesting and complementary.

Eventually I will use both since there are really easy to install (via packages or setuptools) and the output text is so easy to chain.

To give you a little idea of their output:

pep8:

./python_mandelbrot.py:4:11: E401 multiple imports on one line
./python_mandelbrot.py:10:1: E302 expected 2 blank lines, found 1

./python_mandelbrot.py:23:1: W291 trailing whitespace
./python_mandelbrot.py:41:5: E301 expected 1 blank line, found 3

Pylint:

[...] and a very long report with useful stats like :

I found a very simple method that works well:

<input type="text" onclick="this.focus();this.select()">

You can try the following:

rtrim(number_format($coin->current_price,6),'0.')

I'm going to approach this as if you have a Users model:

Users.cs

public class Users
{
    [Key]
    public int UserId { get; set; }

    [Required]
    public string UserName { get; set; }

    public int RoleId { get; set; }

    [ForeignKey("RoleId")]
    public virtual DbUserRoles DbUserRoles { get; set; }
}

and a DbUserRoles model that represented a table by that name in the database:

DbUserRoles.cs

public partial class DbUserRoles
{
    [Key]
    public int UserRoleId { get; set; }

    [Required]
    [StringLength(30)]
    public string UserRole { get; set; }
}

Once you had that cleaned up, you should just be able to create and fill a collection of UserRoles, like this, in your Controller:

var userRoleList = GetUserRolesList();
ViewData["userRoles"] = userRolesList;

and have these supporting functions:

private static SelectListItem[] _UserRolesList;

/// <summary>
/// Returns a static category list that is cached
/// </summary>
/// <returns></returns>
public SelectListItem[] GetUserRolesList()
{
    if (_UserRolesList == null)
    {
        var userRoles = repository.GetAllUserRoles().Select(a => new SelectListItem()
         {
             Text = a.UserRole,
             Value = a.UserRoleId.ToString()
         }).ToList();
         userRoles.Insert(0, new SelectListItem() { Value = "0", Text = "-- Please select your user role --" });

        _UserRolesList = userRoles.ToArray();
    }

    // Have to create new instances via projection
    // to avoid ModelBinding updates to affect this
    // globally
    return _UserRolesList
        .Select(d => new SelectListItem()
    {
         Value = d.Value,
         Text = d.Text
    })
     .ToArray();
}

Repository.cs

My Repository function GetAllUserRoles() for the function, above:

public class Repository
{
    Model1 db = new Model1(); // Entity Framework context

    // User Roles
    public IList<DbUserRoles> GetAllUserRoles()
    {
        return db.DbUserRoles.OrderBy(e => e.UserRoleId).ToList();
    }
}

AddNewUser.cshtml

Then do this in your View:

<table>
    <tr>
        <td>
            @Html.EditorFor(model => model.UserName,
                  htmlAttributes: new { @class = "form-control" }
                  )
        </td>
        <td>
            @Html.DropDownListFor(model => model.RoleId,
                  new SelectList( (IEnumerable<SelectListItem>)ViewData["userRoles"], "Value", "Text", model.RoleId),
                  htmlAttributes: new { @class = "form-control" }
                  )
         </td>
     </tr>
 </table>

The above answers did not help me on Android, thanks to the Pshemo response that worked for me on Android. I will leave some of Pshemo's answer here :

split("\\\\n")

if youd dont have adb in folder android-sdk-macosx/platform-tools/ you should install platform tools first. Run android-sdk-macosx/tools/android and Install platform tools from Android SDK manager.

Here is my simple code FormData with react-native to post request with string and image.

I have used react-native-image-picker to capture/select photo react-native-image-picker

let photo = { uri: source.uri}
let formdata = new FormData();

formdata.append("product[name]", 'test')
formdata.append("product[price]", 10)
formdata.append("product[category_ids][]", 2)
formdata.append("product[description]", '12dsadadsa')
formdata.append("product[images_attributes[0][file]]", {uri: photo.uri, name: 'image.jpg', type: 'image/jpeg'})

NOTE you can change image/jpeg to other content type. You can get content type from image picker response.

fetch('http://192.168.1.101:3000/products',{
  method: 'post',
  headers: {
    'Content-Type': 'multipart/form-data',
  },
  body: formdata
  }).then(response => {
    console.log("image uploaded")
  }).catch(err => {
    console.log(err)
  })  
});

You can use EasyXLS that is a library for exporting Excel files.

Check this code:

DataSet ds = new DataSet();
ds.Tables.Add(dataTable);

ExcelDocument xls = new ExcelDocument();
xls.easy_WriteXLSFile_FromDataSet("datatable.xls", ds, 
           new ExcelAutoFormat(Styles.AUTOFORMAT_EASYXLS1), "DataTable");

See also this sample about how to export datatable to excel in C#.

It seems there is an issue with glibc that affects the memory allocation in Pandas: https://github.com/pandas-dev/pandas/issues/2659

The monkey patch detailed on this issue has resolved the problem for me:

# monkeypatches.py

# Solving memory leak problem in pandas
# https://github.com/pandas-dev/pandas/issues/2659#issuecomment-12021083
import pandas as pd
from ctypes import cdll, CDLL
try:
    cdll.LoadLibrary("libc.so.6")
    libc = CDLL("libc.so.6")
    libc.malloc_trim(0)
except (OSError, AttributeError):
    libc = None

__old_del = getattr(pd.DataFrame, '__del__', None)

def __new_del(self):
    if __old_del:
        __old_del(self)
    libc.malloc_trim(0)

if libc:
    print('Applying monkeypatch for pd.DataFrame.__del__', file=sys.stderr)
    pd.DataFrame.__del__ = __new_del
else:
    print('Skipping monkeypatch for pd.DataFrame.__del__: libc or malloc_trim() not found', file=sys.stderr)

Do it like this: Remember to close iframe tag.

You have to first obtain the Range object. Also, getCell() will not return the value of the cell but instead will return a Range object of the cell. So, use something on the lines of

function email() {

// Opens SS by its ID

var ss = SpreadsheetApp.openById("0AgJjDgtUl5KddE5rR01NSFcxYTRnUHBCQ0stTXNMenc");

// Get the name of this SS

var name = ss.getName();  // Not necessary 

// Read cell 1,1 * Line below does't work *

// var data = Range.getCell(0, 0);
var sheet = ss.getSheetByName('Sheet1'); // or whatever is the name of the sheet 
var range = sheet.getRange(1,1); 
var data = range.getValue();

}

The hierarchy is Spreadsheet --> Sheet --> Range --> Cell.

Do you use https links instead of ssh links? Because the https link is limited by the size of the upload of HttpServer (such as Apache, Ngnix), there is no such restriction when using ssh.

Use the following method to switch to the ssh link.

1. Open terminal.
2. Switch to your project's working directory.
3. Get the name of the remote repository

$ git remote -v
origin  https://github.com/[user_name]/[project_name].git (fetch)
origin  https://github.com/[user_name]/[project_name].git (push)

4. Modify the git address to ssh link.

git remote set-url origin [email protected]:[user_name]/[project_name].git

If you determine the remote repository name, proceed directly to step 4. Now, you can do the push operation happily.

Use this code.

driver.FindElement(By.XPath(".//[@id='header']/div/div[3]/div/form/input[1]")).SendKeys("25025");

lblmessage.Text =Request.ServerVariables["REMOTE_HOST"].ToString();

Just to point out the generic way to iterate over any map:

 private <K, V> void iterateOverMap(Map<K, V> map) {
    for (Map.Entry<K, V> entry : map.entrySet()) {
        System.out.println("key ->" + entry.getKey() + ", value->" + entry.getValue());
    }
    }

Please follow a very simple step. You just have to comment the following line of in the app\http\kernel.php and not app\kernel.php file:

\App\Http\Middleware\VerifyCsrfToken::class,

I hope, it will solve your problem, and let me know if its not working.

This works fine

<?php
      $con=mysqli_connect("localhost","my_user","my_password","my_db");
      $con->query("SET GLOBAL time_zone = 'Asia/Calcutta'");
      $con->query("SET time_zone = '+05:30'");
      $con->query("SET @@session.time_zone = '+05:30'");
?>

Thread.interrupt() sets the interrupted status/flag of the target thread. Then code running in that target thread MAY poll the interrupted status and handle it appropriately. Some methods that block such as Object.wait() may consume the interrupted status immediately and throw an appropriate exception (usually InterruptedException)

Interruption in Java is not pre-emptive. Put another way both threads have to cooperate in order to process the interrupt properly. If the target thread does not poll the interrupted status the interrupt is effectively ignored.

Polling occurs via the Thread.interrupted() method which returns the current thread's interrupted status AND clears that interrupt flag. Usually the thread might then do something such as throw InterruptedException.

EDIT (from Thilo comments): Some API methods have built in interrupt handling. Of the top of my head this includes.

• Object.wait(), Thread.sleep(), and Thread.join()
• Most java.util.concurrent structures
• Java NIO (but not java.io) and it does NOT use InterruptedException, instead using ClosedByInterruptException.

EDIT (from @thomas-pornin's answer to exactly same question for completeness)

Thread interruption is a gentle way to nudge a thread. It is used to give threads a chance to exit cleanly, as opposed to Thread.stop() that is more like shooting the thread with an assault rifle.

Hi i am same problem and resolve this ways.

windows user and vs cant'create .bowerrc file.

in cmd go any folder

install any packages which is contains .bowerrc file forexample

bower install angular-local-storage

this plugin contains .bowerrc file. copy that and go to your project and paste this file.

and in visual studio - solution explorer - show all files and include project seen .bowerrc file

i resolve this ways :)

You told your repository to rebase. It looks like you were on a commit (identified by SHA 9c168a5) and then did git rebase master or git pull --rebase master.

You are rebasing the branch master onto that commit. You can end the rebase via git rebase --abort. This would put back at the state that you were at before you started rebasing.

If it is exactly null (as opposed to not set):

db.states.find({"cities.name": null})

(but as javierfp points out, it also matches documents that have no cities array at all, I'm assuming that they do).

If it's the case that the property is not set:

db.states.find({"cities.name": {"$exists": false}})

I've tested the above with a collection created with these two inserts:

db.states.insert({"cities": [{name: "New York"}, {name: null}]})
db.states.insert({"cities": [{name: "Austin"}, {color: "blue"}]})

The first query finds the first state, the second query finds the second. If you want to find them both with one query you can make an $or query:

db.states.find({"$or": [
  {"cities.name": null}, 
  {"cities.name": {"$exists": false}}
]})

Somewhere you will need to set a fixed height, instead of using auto everywhere. You will find that if you set a fixed height on your content and/or container, then using auto for things inside it will work.

Also, your boxes will still expand height-wise with more content in, even though you have set a height for it - so don't worry about that :)

#container {
  height:500px;
  min-height:500px;
}

If i have understood correct then it is one line of code .It worked for me .

 Collections.reverse(yourList);

Here are the steps you need. Step5 is important if you want the data. Step 2 is where you can select individual tables.

EDIT stack's version isn't quite readable... here's a full-size image http://i.imgur.com/y6ZCL.jpg

In case this helps someone...

You could do this:

<p>This is an <a class="on-new-line">inline link</a>?</p>

With this css:

a.on-new-line:before { 
  content: ' '; 
  font-size:0; 
  display:block;
  line-height:0;
}

You could try this:

SELECT * 
FROM table 
ORDER BY (c_counts+f_counts) 
LIMIT 20

Here is Oliver Steele's image of how it all fits together:

Your url String needs variable markers for the map you pass to work, like:

String url = "https://app.example.com/hr/email?{email}";

Or you could explicitly code the query params into the String to begin with and not have to pass the map at all, like:

String url = "https://app.example.com/hr/[email protected]";

See also https://stackoverflow.com/a/47045624/1357094

Then you'd want to do this instead:

print str(int(1.0/3.0*100))+'%'

The .0 denotes them as floats and int() rounds them to integers afterwards again.

Use pyplot.suptitle or Figure.suptitle:

import matplotlib.pyplot as plt
import numpy as np

fig=plt.figure()
data=np.arange(900).reshape((30,30))
for i in range(1,5):
    ax=fig.add_subplot(2,2,i)        
    ax.imshow(data)

fig.suptitle('Main title') # or plt.suptitle('Main title')
plt.show()

Call the program like this:

(cd /c; /a/helloworld)

The parentheses cause a sub-shell to be spawned. This sub-shell then changes its working directory to /c, then executes helloworld from /a. After the program exits, the sub-shell terminates, returning you to your prompt of the parent shell, in the directory you started from.

Error handling: To avoid running the program without having changed the directory, e.g. when having misspelled /c, make the execution of helloworld conditional:

(cd /c && /a/helloworld)

Reducing memory usage: To avoid having the subshell waste memory while hello world executes, call helloworld via exec:

(cd /c && exec /a/helloworld)

[Thanks to Josh and Juliano for giving tips on improving this answer!]

The second top answer mentions ifeq, however, it fails to mention that these must be on the same level as the name of the target, e.g., to download a file only if it doesn't currently exist, the following code could be used:

download:
ifeq (,$(wildcard ./glob.c))
    curl … -o glob.c
endif

# THIS DOES NOT WORK!
download:
    ifeq (,$(wildcard ./glob.c))
        curl … -o glob.c
    endif

Inside a GitLab CI pipeline the CI_JOB_TOKEN environment variable works for me:

git clone https://gitlab-ci-token:${CI_JOB_TOKEN}@gitlab.com/...

Oh, I see now: only the solution 3 with map() fits with the title of the question.

For Swift 3 Xcode 8.......

let button = UIButton(frame: CGRect(x: 0, y: 0, width: container.width, height: container.height))
        button.addTarget(self, action: #selector(self.barItemTapped), for: .touchUpInside)


func barItemTapped(sender : UIButton) {
    //Write button action here
}

for me the following commands worked:

$ brew install mysql

$ brew services start mysql

Solution to this problem is connected with what @Pace has written in his answer. However, it doesn't explain everything so, if you don't mind, I'll write it by myself.

SOLUTION:

Adding this line:

///<reference path="./../../../typings/globals/jasmine/index.d.ts"/>

at the beginning of hero.spec.ts file fixes problem. Path leads to typings folder (where all typings are stored).

To install typings you need to create typings.json file in root of your project with following content:

{
  "globalDependencies": {
    "core-js": "registry:dt/core-js#0.0.0+20160602141332",
    "jasmine": "registry:dt/jasmine#2.2.0+20160621224255",
    "node": "registry:dt/node#6.0.0+20160807145350"
  }
}

And run typings install (where typings is NPM package).

It looks it's essential to call decode() function to make use of actual string data even after calling base64.b64decode over base64 encoded string. Because never forget it always return bytes literals.

import base64
conv_bytes = bytes('your string', 'utf-8')
print(conv_bytes)                                 # b'your string'
encoded_str = base64.b64encode(conv_bytes)
print(encoded_str)                                # b'eW91ciBzdHJpbmc='
print(base64.b64decode(encoded_str))              # b'your string'
print(base64.b64decode(encoded_str).decode())     # your string

If you put a delete button on each row, then:

<tr>
  <td><input type="button" value="Delete row" onclick="deleteRow(this);">
  <td><input type="text">
  <td><input type="text">

And the deleteRow function can be:

function deleteRow(el) {
    // while there are parents, keep going until reach TR 
    while (el.parentNode && el.tagName.toLowerCase() != 'tr') {
        el = el.parentNode;
    }

    // If el has a parentNode it must be a TR, so delete it
    // Don't delte if only 3 rows left in table
    if (el.parentNode && el.parentNode.rows.length > 3) {
        el.parentNode.removeChild(el);
    }
}

If all your rows have the same content, it will be much faster to add a row by cloning an existing row:

function addRow(tableID) {
    var table = document.getElementById(tableID);

    if (!table) return;

    var newRow = table.rows[1].cloneNode(true);

    // Now get the inputs and modify their names 
    var inputs = newRow.getElementsByTagName('input');

    for (var i=0, iLen=inputs.length; i<iLen; i++) {
        // Update inputs[i]
    }

    // Add the new row to the tBody (required for IE)
    var tBody = table.tBodies[0];
    tBody.insertBefore(newRow, tBody.lastChild);
}

For Guzzle 5, 6 and 7 you do it like this:

use GuzzleHttp\Client;

$client = new Client();

$response = $client->post('url', [
    GuzzleHttp\RequestOptions::JSON => ['foo' => 'bar'] // or 'json' => [...]
]);

Docs

To remove all the documents in all the collections:

db.getCollectionNames().forEach( function(collection_name) { 
    if (collection_name.indexOf("system.") == -1) {
        print ( ["Removing: ", db[collection_name].count({}), " documents from ", collection_name].join('') );
        db[collection_name].remove({}); 
    }
});

If you are referring to the System.Net.HttpClient in .NET 4.5, you can get the content returned by GetAsync using the HttpResponseMessage.Content property as an HttpContent-derived object. You can then read the contents to a string using the HttpContent.ReadAsStringAsync method or as a stream using the ReadAsStreamAsync method.

The HttpClient class documentation includes this example:

  HttpClient client = new HttpClient();
  HttpResponseMessage response = await client.GetAsync("http://www.contoso.com/");
  response.EnsureSuccessStatusCode();
  string responseBody = await response.Content.ReadAsStringAsync();

@Sydney Try putting wp_reset_query() before you call the loop. This will display the content of your page.

<?php
    wp_reset_query(); // necessary to reset query
    while ( have_posts() ) : the_post();
        the_content();
    endwhile; // End of the loop.
?>

EDIT: Try this if you have some other loops that you previously ran. Place wp_reset_query(); where you find it most suitable, but before you call this loop.

Quick answer: the FROM address must exactly match the account you are sending from, or you will get a error 5.7.1 Client does not have permissions to send as this sender.

My guess is that prevents email spoofing with your Office 365 account, otherwise you might be able to send as [email protected].

Another thing to try is in the authentication, fill in the third field with the domain, like

Dim smtpAuth = New System.Net.NetworkCredential(
    "TheDude", "hunter2password", "MicrosoftOffice365Domain.com")

If that doesn't work, double check that you can log into the account at: https://portal.microsoftonline.com

Yet another thing to note is your Antivirus solution may be blocking programmatic access to ports 25 and 587 as a anti-spamming solution. Norton and McAfee may silently block access to these ports. Only enabling Mail and Socket debugging will allow you to notice it (see below).

One last thing to note, the Send method is Asynchronous. If you call

Dispose

Detailed Answer: With Visual Studio (VB.NET or C# doesn't matter), I made a simple form with a button that created the Mail Message, similar to that above. Then I added this to the application.exe.config (in the bin/debug directory of my project). This enables the Output tab to have detailed debug info.

You can use the extend function from JQuery:

var newClone= jQuery.extend({}, oldObject);  
var deepClone = jQuery.extend(true, {}, oldObject); 

There is a Node.js Plugin too:

To do it without JQuery or Plugin read this here:

I am running Anaconda version 4.3.22 and a python3.6.1 environment, and had this problem. Here's the history and the fix:

pip uninstall opencv-python # -- the original step. failed.

ImportError: DLL load failed: The specified module could not be found.

I did this into my python3.6 environment and got this error.

python -m pip install opencv-python # same package as above.
conda install -c conda-forge opencv # separate install parallel to opencv
pip-install opencv-contrib-python # suggested by another user here. doesn't resolve it.

Next, I tried downloading python3.6 and putting the python3.dll in the folder and in various folders. nothing changed.

finally, this fixed it:

pip uninstall opencv-python

(the other conda-forge version is still installed) This left only the conda version, and that works in 3.6.

working!

If you are using ubuntu, check weather subversion is installed or not.

If not then install through command line as

sudo apt-get install subversion

and check following configurations are selected

The easiest way to overwrite a text file is to use a public static field.

this will overwrite the file every time because your only using false the first time through.`

public static boolean appendFile;

Use it to allow only one time through the write sequence for the append field of the write code to be false.

// use your field before processing the write code

appendFile = False;

File fnew=new File("../playlist/"+existingPlaylist.getText()+".txt");
String source = textArea.getText();
System.out.println(source);
FileWriter f2;

try {
     //change this line to read this

    // f2 = new FileWriter(fnew,false);

    // to read this
    f2 = new FileWriter(fnew,appendFile); // important part
    f2.write(source);

    // change field back to true so the rest of the new data will
    // append to the new file.

    appendFile = true;

    f2.close();
 } catch (IOException e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
 }           

You have to code it yourself I'm afraid. I wrote this, and it may be of some use to you

function printtable(table, indent)

  indent = indent or 0;

  local keys = {};

  for k in pairs(table) do
    keys[#keys+1] = k;
    table.sort(keys, function(a, b)
      local ta, tb = type(a), type(b);
      if (ta ~= tb) then
        return ta < tb;
      else
        return a < b;
      end
    end);
  end

  print(string.rep('  ', indent)..'{');
  indent = indent + 1;
  for k, v in pairs(table) do

    local key = k;
    if (type(key) == 'string') then
      if not (string.match(key, '^[A-Za-z_][0-9A-Za-z_]*$')) then
        key = "['"..key.."']";
      end
    elseif (type(key) == 'number') then
      key = "["..key.."]";
    end

    if (type(v) == 'table') then
      if (next(v)) then
        printf("%s%s =", string.rep('  ', indent), tostring(key));
        printtable(v, indent);
      else
        printf("%s%s = {},", string.rep('  ', indent), tostring(key));
      end 
    elseif (type(v) == 'string') then
      printf("%s%s = %s,", string.rep('  ', indent), tostring(key), "'"..v.."'");
    else
      printf("%s%s = %s,", string.rep('  ', indent), tostring(key), tostring(v));
    end
  end
  indent = indent - 1;
  print(string.rep('  ', indent)..'}');
end

If you are using Flutter just run:

flutter doctor --android-licenses 

And accept all the licenses needed.

Mattt Thompson shares a very handy way

switch UIDevice.currentDevice().systemVersion.compare("8.0.0", options: NSStringCompareOptions.NumericSearch) {
case .OrderedSame, .OrderedDescending:
    println("iOS >= 8.0")
case .OrderedAscending:
    println("iOS < 8.0")
}

There's a nice article which may answer your question /only it prints the paths instead of collecting them/. Please note that you can experiment with the C++/Python samples in the online IDE.

http://www.geeksforgeeks.org/find-paths-given-source-destination/

For Windows Vista/7/8/10, you can create a symlink instead via mklink.

Process.Start("cmd.exe", $"/c mklink {linkName} {applicationPath}");

Alternatively, call CreateSymbolicLink via P/Invoke.

anyObject() should fit your needs.

Also, you can always consider implementing hashCode() and equals() for the Bazoo class. This would make your code example work the way you want.

Below are two methods that are superior to looping. Both handle a "no-find" case.

1. The VBA equivalent of a normal function VLOOKUP with error-handling if the variable doesn't exist (INDEX/MATCH may be a better route than VLOOKUP, ie if your two columns A and B were in reverse order, or were far apart)

2. VBAs FIND method (matching a whole string in column A given I use the xlWhole argument)

   Sub Method1()
   Dim strSearch As String
   Dim strOut As String
   Dim bFailed As Boolean
   
   strSearch = "trees"
   
   On Error Resume Next
   strOut = Application.WorksheetFunction.VLookup(strSearch, Range("A:B"), 2, False)
   If Err.Number <> 0 Then bFailed = True
   On Error GoTo 0
   
   If Not bFailed Then
   MsgBox "corresponding value is " & vbNewLine & strOut
   Else
   MsgBox strSearch & " not found"
   End If
   End Sub
   
   Sub Method2()
       Dim rng1 As Range
       Dim strSearch As String
       strSearch = "trees"
       Set rng1 = Range("A:A").Find(strSearch, , xlValues, xlWhole)
       If Not rng1 Is Nothing Then
           MsgBox "Find has matched " & strSearch & vbNewLine & "corresponding cell is " & rng1.Offset(0, 1)
       Else
           MsgBox strSearch & " not found"
       End If
   End Sub
   

I did it like this in my Jtable its autorefreshing after 300 ms;

DefaultTableModel tableModel = new DefaultTableModel(){
public boolean isCellEditable(int nRow, int nCol) {
                return false;
            }
};
JTable table = new JTable();

Timer t = new Timer(300, new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                addColumns();
                remakeData(set);
                table.setModel(model);
            }
        });
        t.start();

private void addColumns() {
        model.setColumnCount(0);
        model.addColumn("NAME");
            model.addColumn("EMAIL");} 

 private void remakeData(CollectionType< Objects > name) {
    model.setRowCount(0);
    for (CollectionType Objects : name){
    String n = Object.getName();
    String e = Object.getEmail();
    model.insertRow(model.getRowCount(),new Object[] { n,e });
    }}

I doubt it will do good with large number of objects like over 500, only other way is to implement TableModelListener in your class, but i did not understand how to use it well. look at http://download.oracle.com/javase/tutorial/uiswing/components/table.html#modelchange

This one works for me:

index.php

    <?php
       if(isset($_GET['action']))
              {
                 //your code
                 echo 'Welcome';
              }
    ?>


    <form id="frm" method="post"  action="?action" >
    <input type="submit" value="Submit" id="submit" />
    </form>

document.getElementById('child') should return you the correct element - remember that id's need to be unique across a document to make it valid anyway.

edit : see this page - ids MUST be unique.

edit edit : alternate way to solve the problem :

<div onclick="test('child1')">
    Test
    <div id="child1">child</div>
</div>

then you just need the test() function to look up the element by id that you passed in.

Try split(",")[i] where i is the index in result array. split gives array below

["test1", " test2", " test3", " test4", " test5"] 

whose element can be accessed by index.

We had a similar issue and we managed to fix it by setting the Platform target to x86.

If you have an association on a property pointing to the user (let's say Credit\Entity\UserCreditHistory#user, picked from your example), then the syntax is quite simple:

public function getHistory($users) {
    $qb = $this->entityManager->createQueryBuilder();
    $qb
        ->select('a', 'u')
        ->from('Credit\Entity\UserCreditHistory', 'a')
        ->leftJoin('a.user', 'u')
        ->where('u = :user')
        ->setParameter('user', $users)
        ->orderBy('a.created_at', 'DESC');

    return $qb->getQuery()->getResult();
}

Since you are applying a condition on the joined result here, using a LEFT JOIN or simply JOIN is the same.

If no association is available, then the query looks like following

public function getHistory($users) {
    $qb = $this->entityManager->createQueryBuilder();
    $qb
        ->select('a', 'u')
        ->from('Credit\Entity\UserCreditHistory', 'a')
        ->leftJoin(
            'User\Entity\User',
            'u',
            \Doctrine\ORM\Query\Expr\Join::WITH,
            'a.user = u.id'
        )
        ->where('u = :user')
        ->setParameter('user', $users)
        ->orderBy('a.created_at', 'DESC');

    return $qb->getQuery()->getResult();
}

This will produce a resultset that looks like following:

array(
    array(
        0 => UserCreditHistory instance,
        1 => Userinstance,
    ),
    array(
        0 => UserCreditHistory instance,
        1 => Userinstance,
    ),
    // ...
)

You can use Len(StrFile) > 0 in loop check statement !

Sub openMyfile()

    Dim Source As String
    Dim StrFile As String

    'do not forget last backslash in source directory.
    Source = "E:\Planning\03\"
    StrFile = Dir(Source)

    Do While Len(StrFile) > 0                        
        Workbooks.Open Filename:=Source & StrFile
        StrFile = Dir()
    Loop
End Sub

Perhaps this should be the select (if I understand the question correctly)

select user.user_fname, user.user_lname, parent.user_fname, parent.user_lname
... As before

You need to #include <stdlib.h>. Otherwise it's defined as int malloc() which is incompatible with the built-in type void *malloc(size_t).

There are a few existing resources you might check:

1. Properly Package Your Java Classes
2. Spring 2.5 Architecture
3. Java Tutorial - Naming a Package
4. SUN Naming Conventions

For what it's worth, my own personal guidelines that I tend to use are as follows:

1. Start with reverse domain, e.g. "com.mycompany".
2. Use product name, e.g. "myproduct". In some cases I tend to have common packages that do not belong to a particular product. These would end up categorized according to the functionality of these common classes, e.g. "io", "util", "ui", etc.
3. After this it becomes more free-form. Usually I group according to project, area of functionality, deployment, etc. For example I might have "project1", "project2", "ui", "client", etc.

A couple of other points:

1. It's quite common in projects I've worked on for package names to flow from the design documentation. Usually products are separated into areas of functionality or purpose already.
2. Don't stress too much about pushing common functionality into higher packages right away. Wait for there to be a need across projects, products, etc., and then refactor.
3. Watch inter-package dependencies. They're not all bad, but it can signify tight coupling between what might be separate units. There are tools that can help you keep track of this.

        if (int.TryParse(txtDepartmentNo.Text, out checkNumber) == false)
        {
            lblMessage.Text = string.Empty;
            lblMessage.Visible = true;
            lblMessage.ForeColor = Color.Maroon;
            lblMessage.Text = "You have not entered a number";
            return;
        }

First of all, you need to check that the IIS is installed in your machine, for that you can go to:

Control Panel --> Add or Remove Programs --> Windows Features --> And Check if Internet Information Services is installed with at least the 'Web Administration Tools' Enabled and The 'World Wide Web Service'

If not, check it, and Press Accept to install it.

Once that is done, you need to go to Administrative Tools in Control Panel and the IIS Will be there. Or simply run inetmgr (after Win+R).

Edit: You should have something like this:

If you have a lot of commits to rebase, and some part of them are giving conflicts, that really hurts. But I can suggest a less-known approach how to "squash all the conflicts".

First, checkout temp branch and start standard merge

git checkout -b temp
git merge origin/master

You will have to resolve conflicts, but only once and only real ones. Then stage all files and finish merge.

git commit -m "Merge branch 'origin/master' into 'temp'"

Then return to your branch (let it be alpha) and start rebase, but with automatical resolving any conflicts.

git checkout alpha
git rebase origin/master -X theirs

Branch has been rebased, but project is probably in invalid state. That's OK, we have one final step. We just need to restore project state, so it will be exact as on branch 'temp'. Technically we just need to copy its tree (folder state) via low-level command git commit-tree. Plus merging into current branch just created commit.

git merge --ff $(git commit-tree temp^{tree} -m "Fix after rebase" -p HEAD)

And delete temporary branch

git branch -D temp

That's all. We did a rebase via hidden merge.

Also I wrote a script, so that can be done in a dialog manner, you can find it here.

If you want to stop it in any moment ticker

ticker := time.NewTicker(500 * time.Millisecond)
go func() {
    for range ticker.C {
        fmt.Println("Tick")
    }
}()
time.Sleep(1600 * time.Millisecond)
ticker.Stop()

If you do not want to stop it tick:

tick := time.Tick(500 * time.Millisecond)
for range tick {
    fmt.Println("Tick")
}

First change the method parameter Enum supportedPermissions to SupportedPermissions supportedPermissions.

Then create your file like this

file = new File
{  
    Name = name,
    Id = id,
    Description = description,
    SupportedPermissions = supportedPermissions
};

And the call to your method should be

CreateFile(id, name, description, SupportedPermissions.basic);

• preg_split if you need to split by regular expressions.
• str_split if you need to split by characters.
• explode if you need to split by something simple.

Also for the future, if you ever want to know what PHP wants you to use if something is deprecated you can always check out the function in the manual and it will tell you alternatives.

Like Vatine wrote: Since go lacks generics it would have to be part of the language and not the standard library. For that you would then have to pollute the language with keywords set, union, intersection, difference, subset...

The other reason is, that it's not clear at all what the "right" implementation of a set is:

1. There is a functional approach:

   func IsInEvenNumbers(n int) bool {
       if n % 2 == 0 {
           return true
       }
      return false
   }
   

This is a set of all even ints. It has a very efficient lookup and union, intersect, difference and subset can easily be done by functional composition.

2. Or you do a has-like approach like Dali showed.

A map does not have that problem, since you store something associated with the value.

As @Steven points out, a better way would be:

public void writeToFile(def directory, def fileName, def extension, def infoList) {
  new File("$directory/$fileName$extension").withWriter { out ->
    infoList.each {
      out.println it
    }
  }
}

As this handles the line separator for you, and handles closing the writer as well

(and doesn't open and close the file each time you write a line, which could be slow in your original version)

There are nice answers here, and i agree with @Austin Greco (the second option with separate components)
There is another way i like, currying.
What you can do is create a function that accept a parameter (your parameter) and returns another function that accepts another parameter (the click event in this case). then you are free to do with it what ever you want.

ES5:

handleChange(param) { // param is the argument you passed to the function
    return function (e) { // e is the event object that returned

    };
}

ES6:

handleChange = param => e => {
    // param is the argument you passed to the function
    // e is the event object that returned
};

And you will use it this way:

<input 
    type="text" 
    onChange={this.handleChange(someParam)} 
/>

Here is a full example of such usage:

const someArr = ["A", "B", "C", "D"];_x000D_
_x000D_
class App extends React.Component {_x000D_
  state = {_x000D_
    valueA: "",_x000D_
    valueB: "some initial value",_x000D_
    valueC: "",_x000D_
    valueD: "blah blah"_x000D_
  };_x000D_
_x000D_
  handleChange = param => e => {_x000D_
    const nextValue = e.target.value;_x000D_
    this.setState({ ["value" + param]: nextValue });_x000D_
  };_x000D_
_x000D_
  render() {_x000D_
    return (_x000D_
      <div>_x000D_
        {someArr.map(obj => {_x000D_
          return (_x000D_
            <div>_x000D_
              <label>_x000D_
                {`input ${obj}   `}_x000D_
              </label>_x000D_
              <input_x000D_
                type="text"_x000D_
                value={this.state["value" + obj]}_x000D_
                onChange={this.handleChange(obj)}_x000D_
              />_x000D_

Note that this approach doesn't solve the creation of a new instance on each render.
I like this approach over the other inline handlers as this one is more concise and readable in my opinion.

Edit:
As suggested in the comments below, you can cache / memoize the result of the function.

Here is a naive implementation:

let memo = {};_x000D_
_x000D_
const someArr = ["A", "B", "C", "D"];_x000D_
_x000D_
class App extends React.Component {_x000D_
  state = {_x000D_
    valueA: "",_x000D_
    valueB: "some initial value",_x000D_
    valueC: "",_x000D_
    valueD: "blah blah"_x000D_
  };_x000D_
_x000D_
  handleChange = param => {_x000D_
    const handler = e => {_x000D_
      const nextValue = e.target.value;_x000D_
      this.setState({ ["value" + param]: nextValue });_x000D_
    }_x000D_
    if (!memo[param]) {_x000D_
      memo[param] = e => handler(e)_x000D_
    }_x000D_
    return memo[param]_x000D_
  };_x000D_
_x000D_
  render() {_x000D_
    return (_x000D_
      <div>_x000D_
        {someArr.map(obj => {_x000D_
          return (_x000D_
            <div key={obj}>_x000D_
              <label>_x000D_
                {`input ${obj}   `}_x000D_
              </label>_x000D_
              <input_x000D_
                type="text"_x000D_
                value={this.state["value" + obj]}_x000D_
                onChange={this.handleChange(obj)}_x000D_
              />_x000D_
              <br />_x000D_
              <br />_x000D_
            </div>_x000D_
          );_x000D_
        })}_x000D_
      </div>_x000D_
    );_x000D_
  }_x000D_
}_x000D_
_x000D_
const rootElement = document.getElementById("root");_x000D_
ReactDOM.render(<App />, rootElement);

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>_x000D_
<div id="root" />

Something like

script > /dev/null 2>&1

This will prevent standard output and error output, redirecting them both to /dev/null.

if you have existing project and you would like to add remote repository url then you need to do following command

git init

if you would like to add readme.md file then you can create it and add it using below command.

git add README.md

make your first commit using below command

git commit -m "first commit"

Now you completed all local repository process, now how you add remote repository url ? check below command this is for ssh url, you can change it for https.

git remote add origin [email protected]:user-name/repository-name.git

How you push your first commit see below command :

git push -u origin master

It can be useful for lazy-loading. Say the object in question is stored in a database, and you don't want to go get it unless you need it. If the object is retrieved by a getter, then the internal object can be null until somebody asks for it, then you can go get it on the first call to the getter.

I had a base page class in a project that was handed to me that was loading some data from a couple different web service calls, but the data in those web service calls wasn't always used in all child pages. Web services, for all of the benefits, pioneer new definitions of "slow", so you don't want to make a web service call if you don't have to.

I moved from public fields to getters, and now the getters check the cache, and if it's not there call the web service. So with a little wrapping, a lot of web service calls were prevented.

So the getter saves me from trying to figure out, on each child page, what I will need. If I need it, I call the getter, and it goes to find it for me if I don't already have it.

    protected YourType _yourName = null;
    public YourType YourName{
      get
      {
        if (_yourName == null)
        {
          _yourName = new YourType();
          return _yourName;
        }
      }
    }

Maybe not as clean or efficient as the already posted solutions, but how about the .each() function? E.g:

var mvar = "";
$(".mbox").each(function() {
    console.log($(this).html());
    mvar += $(this).html();
});
console.log(mvar);

I applied componentDidUpdate to table to have all columns same height. it works same as on $(window).load() in jquery.

eg:

componentDidUpdate: function() {
        $(".tbl-tr").height($(".tbl-tr ").height());
    }

I find until very useful with sleep. example:

> time = Time.now
> sleep 2.seconds until Time.now > time + 10.seconds # breaks when true
# or something like
> sleep 1.seconds until !req.loading # suggested by ohsully

Your Program has invalid/invisible characters in it. You most likely would have picked up these invisible characters when you copy and past code from another website or sometimes a document. Copying the code from the site into another text document and then copying and pasting into your code editor may work, but depending on how long your code is you should just go with typing it out word for word.

In laravel 5.3 $start = Input::get('start'); returns NULL

To solve this

use Illuminate\Support\Facades\Input;

//then inside you controller function  use

$input = Input::all(); // $input will have all your variables,  

$start = $input['start'];
$limit = $input['limit'];

If you use the java keyword abstract you cannot provide an implementation.

Sometimes this idea comes from having a background in C++ and mistaking the virtual keyword in C++ as being "almost the same" as the abstract keyword in Java.

In C++ virtual indicates that a method can be overridden and polymorphism will follow, but abstract in Java is not the same thing. In Java abstract is more like a pure virtual method, or one where the implementation must be provided by a subclass. Since Java supports polymorphism without the need to declare it, all methods are virtual from a C++ point of view. So if you want to provide a method that might be overridden, just write it as a "normal" method.

Now to protect a method from being overridden, Java uses the keyword final in coordination with the method declaration to indicate that subclasses cannot override the method.

Use the Application.FileDialog object

Sub SelectFolder()
    Dim diaFolder As FileDialog
    Dim selected As Boolean

    ' Open the file dialog
    Set diaFolder = Application.FileDialog(msoFileDialogFolderPicker)
    diaFolder.AllowMultiSelect = False
    selected = diaFolder.Show

    If selected Then
        MsgBox diaFolder.SelectedItems(1)
    End If

    Set diaFolder = Nothing
End Sub

Below is example you can use:

create temp table test2 (
  id1  numeric,
  id2  numeric,
  id3  numeric,
  id4  numeric,
  id5  numeric,
  id6  numeric,
  id7  numeric,
  id8  numeric,
  id9  numeric,
  id10 numeric) 
with (oids = false);

do
$do$
declare
     i int;
begin
for  i in 1..100000
loop
    insert into test2  values (random(), i * random(), i / random(), i + random(), i * random(), i / random(), i + random(), i * random(), i / random(), i + random());
end loop;
end;
$do$;

Earlier this could be achieved using DOCKER_OPTS in the /etc/default/docker config file which worked on Ubuntu 14:04 and had some issues on Ubuntu 15:04. Not sure if this has been fixed.

The below line needs to go into the file /etc/default/docker on the host which runs the docker daemon. The change points to the private registry is installed in your local network. Note: you would require to restart the docker service followed with this change.

DOCKER_OPTS="--insecure-registry <priv registry hostname/ip>:<port>"

I would use:

awk 'FNR <= 1' file_*.txt

As @Kusalananda points out there are many ways to capture the first line in command line but using the head -n 1 may not be the best option when using wildcards since it will print additional info. Changing 'FNR == i' to 'FNR <= i' allows to obtain the first i lines.

For example, if you have n files named file_1.txt, ... file_n.txt:

awk 'FNR <= 1' file_*.txt

hello
...
bye

But with head wildcards print the name of the file:

head -1 file_*.txt

==> file_1.csv <==
hello
...
==> file_n.csv <==
bye

This answer is more meant to explain why, not how. The '==' operator in R is vectorized in a same way as the '+' operator. It matches the elements of whatever is on the left side to the elements of whatever is on the right side, per element. For example:

> 1:3 == 1:3
[1] TRUE TRUE TRUE

Here the first test is 1==1 which is TRUE, the second 2==2 and the third 3==3. Notice that this returns a FALSE in the first and second element because the order is wrong:

> 3:1 == 1:3
[1] FALSE  TRUE FALSE

Now if one object is smaller then the other object then the smaller object is repeated as much as it takes to match the larger object. If the size of the larger object is not a multiplication of the size of the smaller object you get a warning that not all elements are repeated. For example:

>  1:2 == 1:3
[1]  TRUE  TRUE FALSE
Warning message:
In 1:2 == 1:3 :
  longer object length is not a multiple of shorter object length

Here the first match is 1==1, then 2==2, and finally 1==3 (FALSE) because the left side is smaller. If one of the sides is only one element then that is repeated:

> 1:3 == 1
[1]  TRUE FALSE FALSE

The correct operator to test if an element is in a vector is indeed '%in%' which is vectorized only to the left element (for each element in the left vector it is tested if it is part of any object in the right element).

Alternatively, you can use '&' to combine two logical statements. '&' takes two elements and checks elementwise if both are TRUE:

> 1:3 == 1 & 1:3 != 2
[1]  TRUE FALSE FALSE

Binding refers to the link between method call and method definition.

This picture clearly shows what is binding.

In this picture, “a1.methodOne()” call is binding to corresponding methodOne() definition and “a1.methodTwo()” call is binding to corresponding methodTwo() definition.

For every method call there should be proper method definition. This is a rule in java. If compiler does not see the proper method definition for every method call, it throws error.

Now, come to static binding and dynamic binding in java.

Static Binding In Java :

Static binding is a binding which happens during compilation. It is also called early binding because binding happens before a program actually runs

.

Static binding can be demonstrated like in the below picture.

In this picture, ‘a1’ is a reference variable of type Class A pointing to object of class A. ‘a2’ is also reference variable of type class A but pointing to object of Class B.

During compilation, while binding, compiler does not check the type of object to which a particular reference variable is pointing. It just checks the type of reference variable through which a method is called and checks whether there exist a method definition for it in that type.

For example, for “a1.method()” method call in the above picture, compiler checks whether there exist method definition for method() in Class A. Because ‘a1' is Class A type. Similarly, for “a2.method()” method call, it checks whether there exist method definition for method() in Class A. Because ‘a2' is also Class A type. It does not check to which object, ‘a1’ and ‘a2’ are pointing. This type of binding is called static binding.

Dynamic Binding In Java :

Dynamic binding is a binding which happens during run time. It is also called late binding because binding happens when program actually is running.

During run time actual objects are used for binding. For example, for “a1.method()” call in the above picture, method() of actual object to which ‘a1’ is pointing will be called. For “a2.method()” call, method() of actual object to which ‘a2’ is pointing will be called. This type of binding is called dynamic binding.

The dynamic binding of above example can be demonstrated like below.

Reference static-binding-and-dynamic-binding-in-java

Please remove e.preventDefault(), because event.cancelable of touchmove is false. So you can't call this method.

Try to comment string "sql-mode=..." in file my.cnf and than restart mysql.

the different way to disable test tasks in the project is:

tasks.withType(Test) {enabled = false}

this behavior needed sometimes if you want to disable tests in one of a project(or the group of projects).

This way working for the all kind of test task, not just a java 'tests'. Also, this way is safe. Here's what I mean let's say: you have a set of projects in different languages: if we try to add this kind of record in main build.gradle:

 subprojects{
 .......
 tests.enabled=false
 .......
}

we will fail in a project when if we have no task called tests

it worked for me adding type="module" to the script importing my mjs:

<script type="module">
import * as module from 'https://rawgit.com/abernier/7ce9df53ac9ec00419634ca3f9e3f772/raw/eec68248454e1343e111f464e666afd722a65fe2/mymod.mjs'

console.log(module.default()) // Prints: Hi from the default export!
</script>

See demo: https://codepen.io/abernier/pen/wExQaa

Try the following:

SELECT * FROM eventList WHERE
date BETWEEN 
STR_TO_DATE('2013/03/26', '%Y/%m/%d')
AND
STR_TO_DATE('2013/03/27', '%y/%m/%d')

A little different to the other answers, using a similar concept but divs instead of pseudoclasses:

input {_x000D_
  position: absolute;_x000D_
  left: 10px;_x000D_
  top: 10px;_x000D_
  width: 50px;_x000D_
  height: 20px;_x000D_
  padding: 0px;_x000D_
  font-size: 14pt;_x000D_
  border: solid 0.5px #000;_x000D_
  z-index: 1;_x000D_
}_x000D_
_x000D_
.spinner-button {_x000D_

  text-align: center;_x000D_
  margin: 0px;_x000D_
  pointer-events: none;_x000D_
  height: 10px;_x000D_

}_x000D_
_x000D_
#inc-button {_x000D_
  left: 46px;_x000D_
  top: 10.5px;_x000D_
}_x000D_
_x000D_
#dec-button {_x000D_
  left: 46px;_x000D_
  top: 20.5px;_x000D_
}

<input type="number" value="0" min="0" max="100"/>_x000D_
<div id="inc-button" class="spinner-button">+</div>_x000D_
<div id="dec-button" class="spinner-button">-</div>

Extract the element:

var buttonMatcherRegExp=/<a[\s\S]*?>[\s\S]*?<\/a>/;
htmlStr=string.match( buttonMatcherRegExp )[0]

Then use jQuery to parse and extract the bit you want:

$(htmlStr).attr('style') 

Well I guess I have found the solution for my own question, here is how I did it:

Eventhough I was being able to successfully run the program using normal python command as well as successfully run pyinstaller and be able to execute the app "new_app.exe" using the command line mentioned in the question which in both cases display the GUI with no problem at all. However, only when I click the application it won't allow to display the GUI and no error is generated.

So, What I did is I added an extra parameter --debug in the pyinstaller command and removing the --windowed parameter so that I can see what is actually happening when the app is clicked and I found out there was an error which made a lot of sense when I trace it, it basically complained that "some_image.jpg" no such file or directory.

The reason why it complains and didn't complain when I ran the script from the first place or even using the command line "./" is because the file image existed in the same path as the script located but when pyinstaller created "dist" directory which has the app product it makes a perfect sense that the image file is not there and so I basically moved it to that dist directory where the clickable app is there!

NULL-safe condition would looks like:

select * from table
where NOT (tester <=> 'username')

export PGPASSWORD=<password>
psql -h <host> -d <database> -U <user_name> -p <port> -a -w -f <file>.sql

If you're interested in something a little more readable (but of course not as efficient,) you could try:

def compare_lists(list1, list2):
    if len(list1) != len(list2): # Weed out unequal length lists.
        return False
    for item in list1:
        if item not in list2:
            return False
    return True

a_list_1 = ['apple', 'orange', 'grape', 'pear']
a_list_2 = ['pear', 'orange', 'grape', 'apple']

b_list_1 = ['apple', 'orange', 'grape', 'pear']
b_list_2 = ['apple', 'orange', 'banana', 'pear']

c_list_1 = ['apple', 'orange', 'grape']
c_list_2 = ['grape', 'orange']

print compare_lists(a_list_1, a_list_2) # Returns True
print compare_lists(b_list_1, b_list_2) # Returns False
print compare_lists(c_list_1, c_list_2) # Returns False

Just had the same issue after VS crashed and Rahul's comment regarding the application pool pointed me in the right direction. In my case recycling the app pool did the trick (IIS Manager => App Pools => right click on ap in question and recycle).

You could try something similar to what Tim Down suggested - but instead of having elements for each pixel on the screen, create just 2-4 elements (boxes), and change their location, width, height dynamically to divide the yet possible locations on screen by 2-4 recursively, thus finding the mouse real location quickly.

For example - first elements take right and left half of screen, afterwards the upper and lower half. By now we already know in which quarter of screen the mouse is located, are able to repeat - discover which quarter of this space...

That is interesting subject. You can play around with two lifecycle hooks to figure out how it works: ngOnChanges and ngOnInit.

Basically when you set default value to Input that's mean it will be used only in case there will be no value coming on that component. And the interesting part it will be changed before component will be initialized.

Let's say we have such components with two lifecycle hooks and one property coming from input.

@Component({
  selector: 'cmp',
})
export class Login implements OnChanges, OnInit {
  @Input() property: string = 'default';

  ngOnChanges(changes) {
    console.log('Changed', changes.property.currentValue, changes.property.previousValue);
  }

  ngOnInit() {
    console.log('Init', this.property);
  }

}

Situation 1

Component included in html without defined property value

As result we will see in console: Init default

That's mean onChange was not triggered. Init was triggered and property value is default as expected.

Situation 2

Component included in html with setted property <cmp [property]="'new value'"></cmp>

As result we will see in console:

Changed new value Object {}

Init new value

And this one is interesting. Firstly was triggered onChange hook, which setted property to new value, and previous value was empty object! And only after that onInit hook was triggered with new value of property.

node v4 and current versions of node

As of ES6 (and so versions of Node greater than v4), a new "template literal" intrinsic type was added to Javascript (denoted by back-ticks "`") which can also be used to construct multi-line strings, as in:

`this is a 
single string`

which evaluates to: 'this is a\nsingle string'.

Note that the newline at the end of the first line is included in the resulting string.

Template literals were added to allow programmers to construct strings where values or code could be directly injected into a string literal without having to use util.format or other templaters, as in:

let num=10;

console.log(`the result of ${num} plus ${num} is ${num + num}.`);

which will print "the result of 10 plus 10 is 20." to the console.

Older versions of node

Older version of node can use a "line continuation" character allowing you to write multi-line strings such as:

'this is a \
single string'

which evaluates to: 'this is a single string'.

Note that the newline at the end of the first line is not included in the resulting string.

There are two possible result rearrangements (following example by @eumiro). Einops package provides a powerful notation to describe such operations non-ambigously

>> a = np.arange(18).reshape(9,2)

# this version corresponds to eumiro's answer
>> einops.rearrange(a, '(x y) z -> z y x', x=3)

array([[[ 0,  6, 12],
        [ 2,  8, 14],
        [ 4, 10, 16]],

       [[ 1,  7, 13],
        [ 3,  9, 15],
        [ 5, 11, 17]]])

# this has the same shape, but order of elements is different (note that each paer was trasnposed)
>> einops.rearrange(a, '(x y) z -> z x y', x=3)

array([[[ 0,  2,  4],
        [ 6,  8, 10],
        [12, 14, 16]],

       [[ 1,  3,  5],
        [ 7,  9, 11],
        [13, 15, 17]]])

You can do it right in your XML file:

android:onClick="@drawable/ic_action_search"

That because your csv file is in invalid format, maybe the line break in your text file is not the \n or \r

and, using c/c++ to parse text is not a good idea. try awk:

 $awk -F"," '{print "ID="$1"\tName="$2"\tAge="$3"\tGender="$4}' 1.csv
 ID=0   Name=Filipe Age=19  Gender=M
 ID=1   Name=Maria  Age=20  Gender=F
 ID=2   Name=Walter Age=60  Gender=M

I have been using google qrcode api for sometime, but I didn't quite like this because it requires me to be on the Internet to access the generated image.

I did a little comand-line research and found out that linux has a command line tool qrencode for generating qr-codes.

I wrote this little script. And the good part is that the generated image is less than 1KB in size. Well the supplied data is simply a url.

$url = ($_SERVER['HTTPS'] ? "https://" : "http://").$_SERVER['HTTP_HOST'].'/profile.php?id='.$_GET['pid'];
$img = shell_exec('qrencode --output=- -m=1 '.escapeshellarg($url));

$imgData = "data:image/png;base64,".base64_encode($img);

Then in the html I load the image:

<img class="emrQRCode" src="<?=$imgData ?>" />

You just need to have installed it. [most imaging apps on linux would have installed it under the hood without you realizing.
