Side Note: Starting at rails 5.0.0 rake has been changed to rails So perform the following

rails db:migrate VERSION=0

The reason is because you are using the transform property twice. Due to CSS rules with the cascade, the last declaration wins if they have the same specificity. As both transform declarations are in the same rule set, this is the case.

What it is doing is this:

1. rotate the text 90 degrees. Ok.
2. translate 50% by 50%. Ok, this is same property as step one, so do this step and ignore step 1.

See http://jsfiddle.net/Lx76Y/ and open it in the debugger to see the first declaration overwritten

As the translate is overwriting the rotate, you have to combine them in the same declaration instead: http://jsfiddle.net/Lx76Y/1/

To do this you use a space separated list of transforms:

#rotatedtext {
    transform-origin: left;
    transform: translate(50%, 50%) rotate(90deg) ;
}

Remember that they are specified in a chain, so the translate is applied first, then the rotate after that.

.contains() is the best method for lists, but for maps you will need to use .containsKey() or .containsValue()

[a:1,b:2,c:3].containsValue(3)
[a:1,b:2,c:3].containsKey('a')

i like the bootstrap3 style as the device width of bootstrap4
so i modify the css as below
<pre>
.visible-xs, .visible-sm, .visible-md, .visible-lg { display:none !important; }
.visible-xs-block, .visible-xs-inline, .visible-xs-inline-block,

@media (max-width:575px) {
table.visible-xs                { display:table !important; }
tr.visible-xs                   { display:table-row !important; }

Create a function in a package and return a SYS_REFCURSOR:

FUNCTION Function1 return SYS_REFCURSOR IS 
       l_cursor SYS_REFCURSOR;
       BEGIN
          open l_cursor for SELECT foo,bar FROM foobar; 
          return l_cursor; 
END Function1;

To add on to what Egon said, simply create your blob called "folder/1.txt", and it will work. No need to create a directory.

this seems to work fine :

dataframe.axes[0].tolist()

Just put the condition into the lambda itself, e.g.

animalMap.entrySet().stream()
        .forEach(
                pair -> {
                    if (pair.getValue() != null) {
                        myMap.put(pair.getKey(), pair.getValue());
                    } else {
                        myList.add(pair.getKey());
                    }
                }
        );

Of course, this assumes that both collections (myMap and myList) are declared and initialized prior to the above piece of code.

Update: using Map.forEach makes the code shorter, plus more efficient and readable, as Jorn Vernee kindly suggested:

    animalMap.forEach(
            (key, value) -> {
                if (value != null) {
                    myMap.put(key, value);
                } else {
                    myList.add(key);
                }
            }
    );

the solution what I found to work in my case

$('#multiselect1').multiselect({
    selectAllValue: 'multiselect-all',
    enableCaseInsensitiveFiltering: true,
    enableFiltering: true,
    maxHeight: '300',
    buttonWidth: '235',
    onChange: function(element, checked) {
        var brands = $('#multiselect1 option:selected');
        var selected = [];
        $(brands).each(function(index, brand){
            selected.push([$(this).val()]);
        });

        console.log(selected);
    }
}); 

add:

Chart.defaults.global.legend.display = false;

in the starting of your script code;

For money: decimal. It costs a little more memory, but doesn't have rounding troubles like double sometimes has.

@jason-mccreary is totally right. Besides I recommend you this code to get more info in case of malfunction:

$rest = curl_exec($crl);

if ($rest === false)
{
    // throw new Exception('Curl error: ' . curl_error($crl));
    print_r('Curl error: ' . curl_error($crl));
}

curl_close($crl);
print_r($rest);

EDIT 1

To debug you can set CURLOPT_HEADER to true to check HTTP response with firebug::net or similar.

curl_setopt($crl, CURLOPT_HEADER, true);

EDIT 2

About Curl error: SSL certificate problem, verify that the CA cert is OK try adding this headers (just to debug, in a production enviroment you should keep these options in true):

curl_setopt($crl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($crl, CURLOPT_SSL_VERIFYPEER, false);

tmp.innerText is undefined. You should use tmp.innerHTML

function strip(html) 
    {  
        var tmp = document.createElement("DIV"); 
        tmp.innerHTML = html; 
        var urlRegex =/(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;   
        return tmp.innerHTML .replace(urlRegex, function(url) {     
        return '\n' + url 
    })

Every platform is going to have a different approach to being able to generate keyboard events. This is because they each need to make use of system libraries (and system extensions). For a cross platform solution, you would need to take each of these solutions and wrap then into a platform check to perform the proper approach.

For windows, you might be able to use the pywin32 extension. win32api.keybd_event

win32api.keybd_event

keybd_event(bVk, bScan, dwFlags, dwExtraInfo)

Simulate a keyboard event

Parameters

bVk : BYTE - Virtual-key code
bScan : BYTE - Hardware scan code
dwFlags=0 : DWORD - Flags specifying various function options
dwExtraInfo=0 : DWORD - Additional data associated with keystroke

You will need to investigate pywin32 for how to properly use it, as I have never used it.

this:

element.setAttribute("onclick", alert("blabla"));

should be:

element.onclick = function () {
  alert("blabla");
}

Because you call alert instead push alert as string in attribute

I don't have grep or other unix on my box but this worked from VSCode's terminal:

git branch -d $(git branch).trim()

I use the lowercase d so it won't delete unmerged branches.

I was also on master when I did it, so * master doesn't exist so it didn't attempt deleting master.

You can achieve almost everything in PROCESS_NUM with this one-liner:

[ `pgrep $1` ] && return 1 || return 0

if you're looking for a partial match, i.e. program is named foobar and you want your $1 to be just foo you can add the -f switch to pgrep:

[[ `pgrep -f $1` ]] && return 1 || return 0

Putting it all together your script could be reworked like this:

#!/bin/bash

check_process() {
  echo "$ts: checking $1"
  [ "$1" = "" ]  && return 0
  [ `pgrep -n $1` ] && return 1 || return 0
}

while [ 1 ]; do 
  # timestamp
  ts=`date +%T`

  echo "$ts: begin checking..."
  check_process "dropbox"
  [ $? -eq 0 ] && echo "$ts: not running, restarting..." && `dropbox start -i > /dev/null`
  sleep 5
done

Running it would look like this:

# SHELL #1
22:07:26: begin checking...
22:07:26: checking dropbox
22:07:31: begin checking...
22:07:31: checking dropbox

# SHELL #2
$ dropbox stop
Dropbox daemon stopped.

# SHELL #1
22:07:36: begin checking...
22:07:36: checking dropbox
22:07:36: not running, restarting...
22:07:42: begin checking...
22:07:42: checking dropbox

Hope this helps!

You mean this?

from string import punctuation, digits

takeout = punctuation + digits

turnthis = "(fjskl) 234 = -345 089 abcdef"
turnthis = turnthis.translate(None, takeout)[::-1]
print turnthis

One of the simple way of using NullSafe Comparator is to use Spring implementation of it, below is one of the simple example to refer :

public int compare(Object o1, Object o2) {
        ValidationMessage m1 = (ValidationMessage) o1;
        ValidationMessage m2 = (ValidationMessage) o2;
        int c;
        if (m1.getTimestamp() == m2.getTimestamp()) {
            c = NullSafeComparator.NULLS_HIGH.compare(m1.getProperty(), m2.getProperty());
            if (c == 0) {
                c = m1.getSeverity().compareTo(m2.getSeverity());
                if (c == 0) {
                    c = m1.getMessage().compareTo(m2.getMessage());
                }
            }
        }
        else {
            c = (m1.getTimestamp() > m2.getTimestamp()) ? -1 : 1;
        }
        return c;
    }

If you're not using AngularJS UI Bootstrap, here's how I did it.

I created a directive that will hold that entire element of your modal, and recompile the element to inject your scope into it.

angular.module('yourApp', []).
directive('myModal',
       ['$rootScope','$log','$compile',
function($rootScope,  $log,  $compile) {
    var _scope = null;
    var _element = null;
    var _onModalShow = function(event) {
        _element.after($compile(event.target)(_scope));
    };

    return {
        link: function(scope, element, attributes) {
            _scope = scope;
            _element = element;
            $(element).on('show.bs.modal',_onModalShow);
        }
    };
}]);

I'm assuming your modal template is inside the scope of your controller, then add directive my-modal to your template. If you saved the clicked user to $scope.aModel, the original template will now work.

Note: The entire scope is now visible to your modal so you can also access $scope.users in it.

<div my-modal id="encouragementModal" class="modal hide fade">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal"
      aria-hidden="true">&times;</button>
    <h3>Confirm encouragement?</h3>
  </div>
  <div class="modal-body">
      Do you really want to encourage <b>{{aModel.userName}}</b>?
  </div>
  <div class="modal-footer">
    <button class="btn btn-info"
      ng-click="encourage('${createLink(uri: '/encourage/')}',{{aModel.userName}})">
      Confirm
    </button>
    <button class="btn" data-dismiss="modal" aria-hidden="true">Never Mind</button>
  </div>
</div>

I'm not sure how necessary this is, and it adds a call to getElementById, but if you're really keen on getting inline JavaScript out of your code, you can pass it as an HTML attribute, namely:

<span class="metadata" id="metadata-size-of-widget" title="<?php echo json_encode($size_of_widget) ?>"></span>

And then in your JavaScript:

var size_of_widget = document.getElementById("metadata-size-of-widget").title;

I agree that Pascal's solution is the way to go, but for those saying that it adds an extra task to remove the comments, you can use the following comment style trick to simplify your life:

<?php /* ?>
<tr>
      <td><?php echo $entry_keyword; ?></td>
      <td><input type="text" name="keyword" value="<?php echo $keyword; ?>" /></td>
    </tr>
    <tr>
      <td><?php echo $entry_sort_order; ?></td>
      <td><input name="sort_order" value="<?php echo $sort_order; ?>" size="1" /></td>
    </tr>
<?php // */ ?>

In order to stop the code block being commented out, simply change the opening comment to:

<?php //* ?>

Jquery.map makes more sense when you are doing work on arrays as it performs very well with arrays.

Jquery.each is best used when iterating through selector items. Which is evidenced in that the map function does not use a selector.

$(selector).each(...)

$.map(arr....)

as you can see, map is not intended to be used with selectors.

Who needs trig when you have complex numbers:

#include <complex.h>
#include <math.h>

#define PI      3.14159265358979323846

typedef complex double Point;

Point point_on_circle ( double radius, double angle_in_degrees, Point centre )
{
    return centre + radius * cexp ( PI * I * ( angle_in_degrees  / 180.0 ) );
}

You're on the right track. The two constructors accept arguments, or you can specify them post-construction with ProcessBuilder#command(java.util.List) and ProcessBuilder#command(String...).

You can't commit empty folders in git. If you want it to show up, you need to put something in it, even just an empty file.

For example, add an empty file called .gitkeep to the folder you want to keep, then in your .gitignore file write:

# exclude everything
somefolder/*

# exception to the rule
!somefolder/.gitkeep 

Commit your .gitignore and .gitkeep files and this should resolve your issue.

Be very careful: NULL is a macro used mainly for pointers. The standard way of terminating a string is:

char *buffer;
...
buffer[end_position] = '\0';

This (below) works also but it is not a big difference between assigning an integer value to a int/short/long array and assigning a character value. This is why the first version is preferred and personally I like it better.

buffer[end_position] = 0; 

As the messages above indicate, the List cannot be differentiated between a List<Object> and a List<String> or List<Integer>.

I've solved this error message for a similar problem:

List<String> strList = (List<String>) someFunction();
String s = strList.get(0);

with the following:

List<?> strList = (List<?>) someFunction();
String s = (String) strList.get(0);

Explanation: The first type conversion verifies that the object is a List without caring about the types held within (since we cannot verify the internal types at the List level). The second conversion is now required because the compiler only knows the List contains some sort of objects. This verifies the type of each object in the List as it is accessed.

All Roads Lead to Rome, but some of them crosses mountains, requires ferries but if you want to get there quickly just take the motorway.

In this case the motorway is to use the execute_batch() feature of psycopg2. The documentation says it the best:

The current implementation of executemany() is (using an extremely charitable understatement) not particularly performing. These functions can be used to speed up the repeated execution of a statement against a set of parameters. By reducing the number of server roundtrips the performance can be orders of magnitude better than using executemany().

In my own test execute_batch() is approximately twice as fast as executemany(), and gives the option to configure the page_size for further tweaking (if you want to squeeze the last 2-3% of performance out of the driver).

The same feature can easily be enabled if you are using SQLAlchemy by setting use_batch_mode=True as a parameter when you instantiate the engine with create_engine()

I faced the same issue and finally managed to solve it. I then created a step-by-step guide containing the universal fix to help all developers get past this issue asap: http://www.dominantwire.com/2015/03/android-sdk-not-opening.html

All the steps in short:

1.If you have jdk v1.8. Remove it and re-install jdk v1.7.x.x

2.Set paths to jdk and jre bin folders in the environment variables

3.delete (make a backup first) the .android folder present in C: > Users > [user-name] > .android

4.Set the JAVA_HOME variable keeping JAVA_HOME as the variable name and the path to bin folder of jdk as the variable value.

5.Go to [sdk-directory] > tools. Find and right-click on android.bat file and select 'edit' to open it in notepad and make the following modifications.

ORIGINAL

set java_exe=
call lib\find_java.bat
if not defined java_exe goto :EOF

MODIFIED

set java_exe=C:\Program Files\Java\jdk1.7.0_75\bin\java.exe
rem call lib\find_java.bat
rem if not defined java_exe goto :EOF

NOTE : Copy and paste your own java.exe path directory as explained previously.

ORIGINAL

for /f "delims=" %%a in ('"%java_exe%" -jar lib\archquery.jar') do set swt_path=lib\%%a

MODIFIED

rem for /f "delims=" %%a in ('"%java_exe%" -jar lib\archquery.jar') do set swt_path=lib\%%a
set swt_path=lib\x86_64

NOTE : If your android sdk is 64bit then mention set swt_path=lib\x86_64 otherwise if it is 32bit then keep it as set swt_path=lib\x86

6. Done! Fire up android sdk from android.bat file or from eclipse. It should open up just fine!

If you don't mind using sed then,

$ cat test 
this is line 1
$ sed -i '$ a\this is line 2 without redirection' test 
$ cat test 
this is line 1
this is line 2 without redirection

As the documentation may be a bit long to go through, some explanations :

• -i means an inplace transformation, so all changes will occur in the file you specify
• $ is used to specify the last line
• a means append a line after
• \ is simply used as a delimiter

In SQL Server, you can do:

select coalesce(format(try_convert(date, col, 112), 'yyyyMMdd'), col)

This attempts the conversion, keeping the previous value if available.

Note: I hope you learned a lesson about storing dates as dates and not strings.

Took me a while to find the new place for expection settings, therefore a new answer.

Since Visual Studio 2015 you control which Exceptions to stop on in the Exception Settings Window (Debug->Windows->Exception Settings). The shortcut is still Ctrl-Alt-E.

The simplest way to handle custom exceptions is selecting "all exceptions not in this list".

Here is a screenshot from the english version:

Here is a screenshot from the german version:

What it seems like to me is that by calling the keys method you're returning to python a dictionary object when it's looking for a list or a tuple. So try taking all of the keys in the dictionary, putting them into a list and then using the for loop.

You tagged the question with both sql-server and plsql so I will provide answers for both SQL Server and Oracle.

In SQL Server you can use FOR XML PATH to concatenate multiple rows together:

select distinct t.[user],
  STUFF((SELECT distinct ', ' + t1.department
         from yourtable t1
         where t.[user] = t1.[user]
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,2,'') department
from yourtable t;

See SQL Fiddle with Demo.

In Oracle 11g+ you can use LISTAGG:

select "User",
  listagg(department, ',') within group (order by "User") as departments
from yourtable
group by "User"

See SQL Fiddle with Demo

Prior to Oracle 11g, you could use the wm_concat function:

select "User",
  wm_concat(department) departments
from yourtable
group by "User"

This has always worked well for me. It's not messy and very clean.

<a href="@Url.Action("Index", "Home")"><span>Text</span></a>

For those facing a similar issue, I found that when 'simulating' a SET = NULL query, PHPMyAdmin would throw an error. It's a red herring.. just run the query and all will be well.

Just want to point out something on @codingbadger answer. When using "ProgressBarRenderer" you should always check for "ProgressBarRenderer.IsSupported" before using the class. For me, this has been a nightmare with Visual Styles errors in Win7 that I couldn't fix. So, a better approach and workaround for the solution would be:

Rectangle clip = new Rectangle(rect.X, rect.Y, (int)Math.Round(((float)Value / Maximum) * rect.Width), rect.Height);
if (ProgressBarRenderer.IsSupported)
  ProgressBarRenderer.DrawHorizontalChunks(g, clip);
else
  g.FillRectangle(new SolidBrush(this.ForeColor), clip);

Notice that the fill will be a simple rectangle and not chunks. Chunks will be used only if ProgressBarRenderer is supported

Simple one liner

[].sort().pop()

 If strMyString.Tostring.Contains("Something") or strMyString.Tostring.Contains("Something2") Then


     End if

You don't need regex for this

>>> s = "Username: How are you today?"

You can use the split method to split the string on the ':' character

>>> s.split(':')
['Username', ' How are you today?']

And slice out element [0] to get the first part of the string

>>> s.split(':')[0]
'Username'

ruby on rails notes has a very nice blogpost about commenting in erb-files

the short version is

to comment a single line use

<%# commented line %>

to comment a whole block use a if false to surrond your code like this

<% if false %>
code to comment
<% end %>

The git diffs have an extra path segment prepended to the file paths. You can strip the this entry in the path by specifying -p1 with patch, like so:

patch -p1 < save.patch

Try below command:

chmod +x gradlew && ./gradlew compileDebug --stacktrace

You Can use below Simple Code:

function checkDelBoxes(pForm, boxName, parent)
{
    for (i = 0; i < pForm.elements.length; i++)
        if (pForm.elements[i].name == boxName)
            pForm.elements[i].checked = parent;
}

Example for Using:

<a href="javascript:;" onclick="javascript:checkDelBoxes($(this).closest('form').get(0), 'CheckBox[]', true);return false;"> Select All
</a>
<a href="javascript:;" onclick="javascript:checkDelBoxes($(this).closest('form').get(0), 'CheckBox[]', false);return false;"> Unselect All
</a>

Use this

select cast((1*1.00)/3 AS DECIMAL(16,2)) as Result

Here in this sql first convert to float or multiply by 1.00 .Which output will be a float number.Here i consider 2 decimal places. You can choose what you need.

What happens if the fragment that you want to remove is not on top of the stack?

Then you can use theses functions

popBackStack(int arg0, int arg1);

popBackStack(String arg0, int arg1);

Using svcutil, you can create interfaces and classes (data contracts) from the WSDL.

svcutil your.wsdl (or svcutil your.wsdl /l:vb if you want Visual Basic)

This will create a file called "your.cs" in C# (or "your.vb" in VB.NET) which contains all the necessary items.

Now, you need to create a class "MyService" which will implement the service interface (IServiceInterface) - or the several service interfaces - and this is your server instance.

Now a class by itself doesn't really help yet - you'll need to host the service somewhere. You need to either create your own ServiceHost instance which hosts the service, configure endpoints and so forth - or you can host your service inside IIS.

None of these https://stackoverflow.com/a/7597360/808128 do work for me. Even "adding assembly referecene to system.web/compilation/assemblies section of the root web.config file". So the two ways remains for me: 1) to add a public wrap class for my assembly that Razor code can access to this assembly through this wrap; 2) just add assembly logic to a public class in the same assembly where the Razor's code is located.

Bringing a bit for users of Sublime Text 2, there is a plugin that gives the base64 code we load the images in the ST.

Called Image2base64: https://github.com/tm-minty/sublime-text-2-image2base64

PS: Never save this file generated by the plugin because it would overwrite the file and would destroy.

You can easily present Html.ActionLink as a button by using the appropriate CSS style. For example:

@Html.ActionLink("Save", "ActionMethod", "Controller", new { @class = "btn btn-primary" })

- Here its more about the coding style than being the functionality....

- The 1st option is very clear, but then the 2nd one is quite elegant... no offense, its just my view..

From the manual, pathinfo:

<?php
    $path_parts = pathinfo('/www/htdocs/index.html');

    echo $path_parts['dirname'], "\n";
    echo $path_parts['basename'], "\n";
    echo $path_parts['extension'], "\n";
    echo $path_parts['filename'], "\n"; // Since PHP 5.2.0
?>

It doesn't have to be a complete path to operate properly. It will just as happily parse file.jpg as /path/to/my/file.jpg.

(Update) V5.1 & Hooks (Requires React >= 16.8)

You can use useHistory, useLocation and useRouteMatch in your component to get match, history and location .

const Child = () => {
  const location = useLocation();
  const history = useHistory();
  const match = useRouteMatch("write-the-url-you-want-to-match-here");

  return (
    <div>{location.pathname}</div>
  )
}

export default Child

(Update) V4 & V5

You can use withRouter HOC in order to inject match, history and location in your component props.

class Child extends React.Component {
  static propTypes = {
    match: PropTypes.object.isRequired,
    location: PropTypes.object.isRequired,
    history: PropTypes.object.isRequired
  }

  render() {
    const { match, location, history } = this.props

    return (
      <div>{location.pathname}</div>
    )
  }
}

export default withRouter(Child)

(Update) V3

You can use withRouter HOC in order to inject router, params, location, routes in your component props.

class Child extends React.Component {

  render() {
    const { router, params, location, routes } = this.props

    return (
      <div>{location.pathname}</div>
    )
  }
}

export default withRouter(Child)

Original answer

If you don't want to use the props, you can use the context as described in React Router documentation

First, you have to set up your childContextTypes and getChildContext

class App extends React.Component{

  getChildContext() {
    return {
      location: this.props.location
    }
  }

  render() {
    return <Child/>;
  }
}

App.childContextTypes = {
    location: React.PropTypes.object
}

Then, you will be able to access to the location object in your child components using the context like this

class Child extends React.Component{

   render() {
     return (
       <div>{this.context.location.pathname}</div>
     )
   }

}

Child.contextTypes = {
    location: React.PropTypes.object
 }

A workaround is to use a willAnswer() method.

For example the following works (and doesn't throw a MockitoException but actually throws a checked Exception as required here) using BDDMockito:

given(someObj.someMethod(stringArg1)).willAnswer( invocation -> { throw new Exception("abc msg"); });

The equivalent for plain Mockito would to use the doAnswer method

random.sample(population, k)

It is used for randomly sampling a sample of length 'k' from a population. returns a 'k' length list of unique elements chosen from the population sequence or set

it returns a new list and leaves the original population unchanged and the resulting list is in selection order so that all sub-slices will also be valid random samples

I am putting up an example in which I am splitting a dataset randomly. It is basically a function in which you pass x_train(population) as an argument and return indices of 60% of the data as D_test.

import random

def randomly_select_70_percent_of_data_from_1_to_length(x_train):
    return random.sample(range(0, len(x_train)), int(0.6*len(x_train)))

      library(stringi)

            group <- c('12357e', '12575e', '12575e', ' 197e18',  'e18947')

            pattern <- "e"  
            replacement <-  ""  
            group <- str_replace(group, pattern, replacement)      
            group    

[1] "12357"  "12575"  "12575"  " 19718" "18947" 

Swift

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    // your code

    // your code

    // and use deselect row to end line of this function

    self.tableView.deselectRowAtIndexPath(indexPath, animated: true)

}

In a context like this

function ActionLink() {
  function handleClick(e) {
    e.preventDefault();
    console.log('The link was clicked.');
  }

  return (
    <a href="#" onClick={handleClick}>
      Click me
    </a>
  );
}

As you can see, you have to call preventDefault() explicitly. I think that this docs, could be helpful.

As stated here: Package names are written in all lower case to avoid conflict with the names of classes or interfaces.

Companies use their reversed Internet domain name to begin their package names—for example, com.example.mypackage for a package named mypackage created by a programmer at example.com.

Name collisions that occur within a single company need to be handled by convention within that company, perhaps by including the region or the project name after the company name (for example, com.example.region.mypackage).

Packages in the Java language itself begin with java. or javax.

In some cases, the internet domain name may not be a valid package name. This can occur if the domain name contains a hyphen or other special character, if the package name begins with a digit or other character that is illegal to use as the beginning of a Java name, or if the package name contains a reserved Java keyword, such as "int". In this event, the suggested convention is to add an underscore. For example:

In My case I had one nuget package that was installed in my project however package folder was never checked in to TFS therefore, in build machine that nuget package bin files were missing. And hence in production I was getting this error. I had to compare the bin folder over production vs my local then I found which dlls are missing and I found that those were belonging to one nuget package.

Sorry to be so late to the party! I came across a similar issue, in WinRT. I'm not sure whether you're using WPF or WinRT, but they do differ in some ways (some better than others). Hopefully this will help people across the board, whichever situation they're in.

You could always use the code from the converter class I created to re-use and do in your C# code-behind, or wherever you're using it, to be honest:

I made it with the intention that a 6-digit (RGB), or an 8-digit (ARGB) Hex value could be used either way.

So I created a converter class:

public class StringToSolidColorBrushConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, string language)
    {
        var hexString = (value as string).Replace("#", "");

        if (string.IsNullOrWhiteSpace(hexString)) throw new FormatException();
        if (hexString.Length != 6 || hexString.Length != 8) throw new FormatException();

        try
        {
            var a = hexString.Length == 8 ? hexString.Substring(0, 2) : "255";
            var r = hexString.Length == 8 ? hexString.Substring(2, 2) : hexString.Substring(0, 2);
            var g = hexString.Length == 8 ? hexString.Substring(4, 2) : hexString.Substring(2, 2);
            var b = hexString.Length == 8 ? hexString.Substring(6, 2) : hexString.Substring(4, 2);

            return new SolidColorBrush(ColorHelper.FromArgb(
                byte.Parse(a, System.Globalization.NumberStyles.HexNumber),
                byte.Parse(r, System.Globalization.NumberStyles.HexNumber),
                byte.Parse(g, System.Globalization.NumberStyles.HexNumber),
                byte.Parse(b, System.Globalization.NumberStyles.HexNumber)));
        }
        catch
        {
            throw new FormatException();
        }
    }

    public object ConvertBack(object value, Type targetType, object parameter, string language)
    {
        throw new NotImplementedException();
    }
}

Added it into my App.xaml:

<ResourceDictionary>
    ...
    <converters:StringToSolidColorBrushConverter x:Key="StringToSolidColorBrushConverter" />
    ...
</ResourceDictionary>

And used it in my View's Xaml:

<Grid>
    <Rectangle Fill="{Binding RectangleColour,
               Converter={StaticResource StringToSolidColorBrushConverter}}"
               Height="20" Width="20" />
</Grid>

Works a charm!

Side note... Unfortunately, WinRT hasn't got the System.Windows.Media.BrushConverter that H.B. suggested; so I needed another way, otherwise I would have made a VM property that returned a SolidColorBrush (or similar) from the RectangleColour string property.

MySQL has the string function QUOTE, and it should solve this problem:

$cat abs.sh
#!/bin/bash
echo "$(cd "$(dirname "$1")"; pwd -P)"

Some explanations:

1. This script get relative path as argument "$1"
2. Then we get dirname part of that path (you can pass either dir or file to this script): dirname "$1"
3. Then we cd "$(dirname "$1"); into this relative dir
4. pwd -P and get absolute path. The -P option will avoid symlinks
5. As final step we echo it

Then run your script:

abs.sh your_file.txt

I used AtomicInteger to solve the Dining Philosopher's problem.

In my solution, AtomicInteger instances were used to represent the forks, there are two needed per philosopher. Each Philosopher is identified as an integer, 1 through 5. When a fork is used by a philosopher, the AtomicInteger holds the value of the philosopher, 1 through 5, otherwise the fork is not being used so the value of the AtomicInteger is -1.

The AtomicInteger then allows to check if a fork is free, value==-1, and set it to the owner of the fork if free, in one atomic operation. See code below.

AtomicInteger fork0 = neededForks[0];//neededForks is an array that holds the forks needed per Philosopher
AtomicInteger fork1 = neededForks[1];
while(true){    
    if (Hungry) {
        //if fork is free (==-1) then grab it by denoting who took it
        if (!fork0.compareAndSet(-1, p) || !fork1.compareAndSet(-1, p)) {
          //at least one fork was not succesfully grabbed, release both and try again later
            fork0.compareAndSet(p, -1);
            fork1.compareAndSet(p, -1);
            try {
                synchronized (lock) {//sleep and get notified later when a philosopher puts down one fork                    
                    lock.wait();//try again later, goes back up the loop
                }
            } catch (InterruptedException e) {}

        } else {
            //sucessfully grabbed both forks
            transition(fork_l_free_and_fork_r_free);
        }
    }
}

Because the compareAndSet method does not block, it should increase throughput, more work done. As you may know, the Dining Philosophers problem is used when controlled accessed to resources is needed, i.e. forks, are needed, like a process needs resources to continue doing work.

You must pip install pyserial first.

Use mogrify tool from ImageMagick package to remove alpha channel.

brew install imagemagick
cd folder_with_images
mogrify -alpha off */*.png

Update from May 3

You can tell whether image contains alpha channel by running:

sips -g all image.png

In case you render screenshots in iOS Simulator you can drop alpha channel by passing BOOL opaque = YES to UIGraphicsBeginImageContextWithOptions:

UIGraphicsBeginImageContextWithOptions(imageSize, YES, 0); 

I would reach for Python in this situation, to avoid optimistically assuming paths without spaces or slashes. I've also found that python2 tends to be installed in more places than rename.

#!/usr/bin/env python2
import sys, os

def rename_dir(directory):
  print('DEBUG: rename('+directory+')')

  # Rename current directory if needed
  os.rename(directory, directory.lower())
  directory = directory.lower()

  # Rename children
  for fn in os.listdir(directory):
    path = os.path.join(directory, fn)
    os.rename(path, path.lower())
    path = path.lower()

    # Rename children within, if this child is a directory
    if os.path.isdir(path):
        rename_dir(path)

# Run program, using the first argument passed to this Python script as the name of the folder
rename_dir(sys.argv[1])

It should just be

name[0].firstChild.nodeValue

There really aren't any differences.

" is processed as " which is the decimal equivalent of &x22; which is the ISO 8859-1 equivalent of ".

The only reason you may be against using " is because it was mistakenly omitted from the HTML 3.2 specification.

Otherwise it all boils down to personal preference.

Similar to above, but I used (this was in CSHTML):

JavaScript:

var value = "Hello World!"<br>
$('.output').html(value);

CSHTML:

<div class="output"></div>

Try this,

$('td').click(function(){
   var row_index = $(this).parent().index();
   var col_index = $(this).index();
});

If you need the index of table contain td then you can change it to

var row_index = $(this).parent('table').index(); 

This solved my problem : Sample alter table statement to change the ownership.

ALTER TABLE databasechangelog OWNER TO arwin_ash;
ALTER TABLE databasechangeloglock OWNER TO arwin_ash;

Per https://developer.mozilla.org/en-US/docs/Web/API/WindowBase64/Base64_encoding_and_decoding and http://en.wikipedia.org/wiki/Basic_access_authentication , here is how to do Basic auth with a header instead of putting the username and password in the URL. Note that this still doesn't hide the username or password from anyone with access to the network or this JS code (e.g. a user executing it in a browser):

$.ajax({
  type: 'POST',
  url: http://theappurl.com/api/v1/method/,
  data: {},
  crossDomain: true,
  beforeSend: function(xhr) {
    xhr.setRequestHeader('Authorization', 'Basic ' + btoa(unescape(encodeURIComponent(YOUR_USERNAME + ':' + YOUR_PASSWORD))))
  }
});

Try using the os module.

import os

os.environ['DEBUSSY'] = '1'
os.environ['FSDB'] = '1'

# Open child processes via os.system(), popen() or fork() and execv()

someVariable = int(os.environ['DEBUSSY'])

See the Python docs on os.environ. Also, for spawning child processes, see Python's subprocess docs.

To add to craig_h's comment above (I currently don't have enough rep to add this as a comment to his answer, sorry), if your primary key is not an integer, you'll also want to tell your model what data type it is, by setting keyType at the top of the model definition.

public $keyType = 'string'

Eloquent understands any of the types defined in the castAttribute() function, which as of Laravel 5.4 are: int, float, string, bool, object, array, collection, date and timestamp.

This will ensure that your primary key is correctly cast into the equivalent PHP data type.

If you are using PDO, you can use the PDO::quote method.

Invoking javap to read the bytecode

The javap command takes class-names without the .class extension. Try

javap -c ClassName

Converting .class files back to .java files

javap will however not give you the implementations of the methods in java-syntax. It will at most give it to you in JVM bytecode format.

To actually decompile (i.e., do the reverse of javac) you will have to use proper decompiler. See for instance the following related question:

• How do I "decompile" Java class files?

LibGDX is one of the best engines I've ever used, works on almost all platforms, and performs twice as fast as cocos2d-x in most tests I've done. You can use any JVM language you like. Here's a 13 part tutorial in Java, and here's a bunch using jruby. There's a good skeletal animation tool that works with it here, and it has baked in support for tiled TMX maps as well. The ui framework is awesome, and it has a scene graph and actor style API similar to cocos2d scenes, sprites and actions. The community is awesome, updates are frequent, and the documentation is good. Don't let the java part scare you, it's fast, and you can use jruby or scala or whatever you like. I highly recommend it for 2d or 3d work, it supports both.

Jar is an archive, you can replace a file in it by yourself in your favourite file manager (Total Commander for example).

I was getting this same error on my DigitalOcean Ubuntu server.

I tried changing the max_allowed_packet and the wait_timeout settings but neither of them fixed it.

It turns out that my server was out of RAM. I added a 1GB swap file and that fixed my problem.

Check your memory with free -h to see if that's what's causing it.

You need to hook to console exit event and not your process.

Capture console exit C#

For Samsung Galaxy s4 i resolved issue by instaling Kies software, after that everything works like a charm.

class Test{
    const A = 1;
    public $b = 'two';
    private $c = test::A;

    public function __toArray(){
        return call_user_func('get_object_vars', $this);
    }
}

$my_test = new Test();
var_dump((array)$my_test);
var_dump($my_test->__toArray());

Output

array(2) {
    ["b"]=>
    string(3) "two"
    ["Testc"]=>
    int(1)
}
array(1) {
    ["b"]=>
    string(3) "two"
}

I finally found the problem. The error was not the good one.

Apparently, Ole DB source have a bug that might make it crash and throw that error. I replaced the OLE DB destination with a OLE DB Command with the insert statement in it and it fixed it.

Strange Bug, Hope it will help other people.

In this answer I will describe the three methods of defining DOM event handlers.

element.addEventListener()

Code example:

const element = document.querySelector('a');_x000D_
element.addEventListener('click', event => event.preventDefault(), true);

<a href="//google.com">Try clicking this link.</a>

element.addEventListener() has multiple advantages:

• Allows you to register unlimited events handlers and remove them with element.removeEventListener().
• Has useCapture parameter, which indicates whether you'd like to handle event in its capturing or bubbling phase. See: Unable to understand useCapture attribute in addEventListener.
• Cares about semantics. Basically, it makes registering event handlers more explicit. For a beginner, a function call makes it obvious that something happens, whereas assigning event to some property of DOM element is at least not intuitive.
• Allows you to separate document structure (HTML) and logic (JavaScript). In tiny web applications it may not seem to matter, but it does matter with any bigger project. It's way much easier to maintain a project which separates structure and logic than a project which doesn't.
• Eliminates confusion with correct event names. Due to using inline event listeners or assigning event listeners to .onevent properties of DOM elements, lots of inexperienced JavaScript programmers thinks that the event name is for example onclick or onload. on is not a part of event name. Correct event names are click and load, and that's how event names are passed to .addEventListener().
• Works in almost all browser. If you still have to support IE <= 8, you can use a polyfill from MDN.

element.onevent = function() {} (e.g. onclick, onload)

Code example:

const element = document.querySelector('a');_x000D_
element.onclick = event => event.preventDefault();

<a href="//google.com">Try clicking this link.</a>

This was a way to register event handlers in DOM 0. It's now discouraged, because it:

• Allows you to register only one event handler. Also removing the assigned handler is not intuitive, because to remove event handler assigned using this method, you have to revert onevent property back to its initial state (i.e. null).
• Doesn't respond to errors appropriately. For example, if you by mistake assign a string to window.onload, for example: window.onload = "test";, it won't throw any errors. Your code wouldn't work and it would be really hard to find out why. .addEventListener() however, would throw error (at least in Firefox): TypeError: Argument 2 of EventTarget.addEventListener is not an object.
• Doesn't provide a way to choose if you want to handle event in its capturing or bubbling phase.

Inline event handlers (onevent HTML attribute)

Code example:

<a href="//google.com" onclick="event.preventDefault();">Try clicking this link.</a>

Similarly to element.onevent, it's now discouraged. Besides the issues that element.onevent has, it:

• Is a potential security issue, because it makes XSS much more harmful. Nowadays websites should send proper Content-Security-Policy HTTP header to block inline scripts and allow external scripts only from trusted domains. See How does Content Security Policy work?
• Doesn't separate document structure and logic.
• If you generate your page with a server-side script, and for example you generate a hundred links, each with the same inline event handler, your code would be much longer than if the event handler was defined only once. That means the client would have to download more content, and in result your website would be slower.

It looks like you have everything correct according to Laravel docs, but you have a typo

$item->push($product);

Should be

$items->push($product);

I also want to think the actual method you're looking for is put

$items->put('products', $product);

So what will happen if two threads attack a volatile primitive variable at same time?

Usually each one can increment the value. However sometime, both will update the value at the same time and instead of incrementing by 2 total, both thread increment by 1 and only 1 is added.

Does this mean that whosoever takes lock on it, that will be setting its value first.

There is no lock. That is what synchronized is for.

And in if meantime, some other thread comes up and read old value while first thread was changing its value, then doesn't new thread will read its old value?

Yes,

What is the difference between Atomic and volatile keyword?

AtomicXxxx wraps a volatile so they are basically same, the difference is that it provides higher level operations such as CompareAndSwap which is used to implement increment.

AtomicXxxx also supports lazySet. This is like a volatile set, but doesn't stall the pipeline waiting for the write to complete. It can mean that if you read a value you just write you might see the old value, but you shouldn't be doing that anyway. The difference is that setting a volatile takes about 5 ns, bit lazySet takes about 0.5 ns.

I want to add one more thing to the @netbrain's answer relevant in case you use server-side processing (see serverSide option).

Query throttling performed by default by datatables (see searchDelay option) does not apply to the .search() API call. You can get it back by using $.fn.dataTable.util.throttle() in the following way:

var table = $('#myTable').DataTable();
var search = $.fn.dataTable.util.throttle(
    function(val) {
        table.search(val).draw();
    },
    400  // Search delay in ms
);

$('#mySearchBox').keyup(function() {
    search(this.value);
});

You can use this command.

git diff --cached --name-only

The --cached option of git diff means to get staged files, and the --name-only option means to get only names of the files.

1. You can iterate through directories listed in sys.path to find all modules (except builtin ones).
2. It'll probably be somewhere around /usr/lib/pythonX.X/site-packages (again, see sys.path). And consider using native Python package management (via pip or easy_install, plus yolk) instead, packages in Linux distros-maintained repositories tend to be outdated.

Actually, the toString() implementation does a join with commas by default:

var arr = [ 42, 55 ];
var str1 = arr.toString(); // Gives you "42,55"
var str2 = String(arr); // Ditto

I don't know if this is mandated by the JS spec but this is what most pretty much all browsers seem to be doing.

To check a space symbol you can use the following approach

if ( c == ' ' ) { /*...*/ }

To check a space and/or a tab symbol (standard blank characters) you can use the following approach

#include <ctype.h>

//...

if ( isblank( c ) ) { /*...*/ }

To check a white space you can use the following approach

#include <ctype.h>

//...

if ( isspace( c ) ) { /*...*/ }

In case you are using fish shell and do not want to add to $path for security reason. We can add the below function to run local node executables.

### run executables in node_module/.bin directory
function n 
  set -l npmbin (npm bin)   
  set -l argvCount (count $argv)
  switch $argvCount
    case 0
      echo please specify the local node executable as 1st argument
    case 1
      # for one argument, we can eval directly 
      eval $npmbin/$argv
    case '*'
      set --local executable $argv[1]
      # for 2 or more arguments we cannot append directly after the $npmbin/ since the fish will apply each array element after the the start string: $npmbin/arg1 $npmbin/arg2... 
      # This is just how fish interoperate array. 
      set --erase argv[1]
      eval $npmbin/$executable $argv 
  end
end

Now you can run thing like:

n coffee

or more arguments like:

n browser-sync --version

Note, if you are bash user, then @Bob9630 answers is the way to go by leveraging bash's $@, which is not available in fishshell.

Your query execution will return list of Object[].

List result_source = LoadSource.list();
for(Object[] objA : result_source) {
    // read it all
}

To see both of the structure and location (directory) of an any (internal or external)table, we can use table's create statment-

show create table table_name;

Apparently there is no small simple cheap utility that would help performing this task. There is however 101 way to do it in a complicated and inconvenient manner.

Following article describes several. There are probably dozens more... http://www.petefinnigan.com/ramblings/how_to_set_trace.htm

I'm going to go against the general wisdom here that std::copy will have a slight, almost imperceptible performance loss. I just did a test and found that to be untrue: I did notice a performance difference. However, the winner was std::copy.

I wrote a C++ SHA-2 implementation. In my test, I hash 5 strings using all four SHA-2 versions (224, 256, 384, 512), and I loop 300 times. I measure times using Boost.timer. That 300 loop counter is enough to completely stabilize my results. I ran the test 5 times each, alternating between the memcpy version and the std::copy version. My code takes advantage of grabbing data in as large of chunks as possible (many other implementations operate with char / char *, whereas I operate with T / T * (where T is the largest type in the user's implementation that has correct overflow behavior), so fast memory access on the largest types I can is central to the performance of my algorithm. These are my results:

Time (in seconds) to complete run of SHA-2 tests

std::copy   memcpy  % increase
6.11        6.29    2.86%
6.09        6.28    3.03%
6.10        6.29    3.02%
6.08        6.27    3.03%
6.08        6.27    3.03%

Total average increase in speed of std::copy over memcpy: 2.99%

My compiler is gcc 4.6.3 on Fedora 16 x86_64. My optimization flags are -Ofast -march=native -funsafe-loop-optimizations.

Code for my SHA-2 implementations.

I decided to run a test on my MD5 implementation as well. The results were much less stable, so I decided to do 10 runs. However, after my first few attempts, I got results that varied wildly from one run to the next, so I'm guessing there was some sort of OS activity going on. I decided to start over.

Same compiler settings and flags. There is only one version of MD5, and it's faster than SHA-2, so I did 3000 loops on a similar set of 5 test strings.

These are my final 10 results:

Time (in seconds) to complete run of MD5 tests

5.52        5.56        +0.72%

5.57        5.53        -0.72%

5.57        5.56        -0.18%

Total average decrease in speed of std::copy over memcpy: 0.11%

Code for my MD5 implementation

These results suggest that there is some optimization that std::copy used in my SHA-2 tests that std::copy could not use in my MD5 tests. In the SHA-2 tests, both arrays were created in the same function that called std::copy / memcpy. In my MD5 tests, one of the arrays was passed in to the function as a function parameter.

I did a little bit more testing to see what I could do to make std::copy faster again. The answer turned out to be simple: turn on link time optimization. These are my results with LTO turned on (option -flto in gcc):

Time (in seconds) to complete run of MD5 tests with -flto

std::copy   memcpy      % difference
5.54        5.57        +0.54%
5.50        5.53        +0.54%
5.54        5.58        +0.72%
5.50        5.57        +1.26%
5.54        5.58        +0.72%
5.54        5.57        +0.54%
5.54        5.56        +0.36%
5.54        5.58        +0.72%
5.51        5.58        +1.25%
5.54        5.57        +0.54%

Total average increase in speed of std::copy over memcpy: 0.72%

In summary, there does not appear to be a performance penalty for using std::copy. In fact, there appears to be a performance gain.

Explanation of results

So why might std::copy give a performance boost?

First, I would not expect it to be slower for any implementation, as long as the optimization of inlining is turned on. All compilers inline aggressively; it is possibly the most important optimization because it enables so many other optimizations. std::copy can (and I suspect all real world implementations do) detect that the arguments are trivially copyable and that memory is laid out sequentially. This means that in the worst case, when memcpy is legal, std::copy should perform no worse. The trivial implementation of std::copy that defers to memcpy should meet your compiler's criteria of "always inline this when optimizing for speed or size".

However, std::copy also keeps more of its information. When you call std::copy, the function keeps the types intact. memcpy operates on void *, which discards almost all useful information. For instance, if I pass in an array of std::uint64_t, the compiler or library implementer may be able to take advantage of 64-bit alignment with std::copy, but it may be more difficult to do so with memcpy. Many implementations of algorithms like this work by first working on the unaligned portion at the start of the range, then the aligned portion, then the unaligned portion at the end. If it is all guaranteed to be aligned, then the code becomes simpler and faster, and easier for the branch predictor in your processor to get correct.

Premature optimization?

std::copy is in an interesting position. I expect it to never be slower than memcpy and sometimes faster with any modern optimizing compiler. Moreover, anything that you can memcpy, you can std::copy. memcpy does not allow any overlap in the buffers, whereas std::copy supports overlap in one direction (with std::copy_backward for the other direction of overlap). memcpy only works on pointers, std::copy works on any iterators (std::map, std::vector, std::deque, or my own custom type). In other words, you should just use std::copy when you need to copy chunks of data around.

Create a new style

<style name="my_dialog_theme" parent="ThemeOverlay.AppCompat.Dialog">
    <item name="colorAccent">@color/colorAccent</item>                   <!--header background-->
    <item name="android:windowBackground">@color/colorPrimary</item>     <!--calendar background-->
    <item name="android:colorControlActivated">@color/colorAccent</item> <!--selected day-->
    <item name="android:textColorPrimary">@color/colorPrimaryText</item> <!--days of the month-->
    <item name="android:textColorSecondary">@color/colorAccent</item>    <!--days of the week-->
</style>

Then initialize the dialog

Calendar mCalendar = new GregorianCalendar();
mCalendar.setTime(new Date());

new DatePickerDialog(mContext, R.style.my_dialog_theme, new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        //do something with the date
    }
}, mCalendar.get(Calendar.YEAR), mCalendar.get(Calendar.MONTH), mCalendar.get(Calendar.DAY_OF_MONTH)).show();

Result:

There is now an ELMAH.MVC package in NuGet that includes an improved solution by Atif and also a controller that handles the elmah interface within MVC routing (no need to use that axd anymore)
The problem with that solution (and with all the ones here) is that one way or another the elmah error handler is actually handling the error, ignoring what you might want to set up as a customError tag or through ErrorHandler or your own error handler
The best solution IMHO is to create a filter that will act at the end of all the other filters and log the events that have been handled already. The elmah module should take care of loging the other errors that are unhandled by the application. This will also allow you to use the health monitor and all the other modules that can be added to asp.net to look at error events

I wrote this looking with reflector at the ErrorHandler inside elmah.mvc

public class ElmahMVCErrorFilter : IExceptionFilter
{
   private static ErrorFilterConfiguration _config;

   public void OnException(ExceptionContext context)
   {
       if (context.ExceptionHandled) //The unhandled ones will be picked by the elmah module
       {
           var e = context.Exception;
           var context2 = context.HttpContext.ApplicationInstance.Context;
           //TODO: Add additional variables to context.HttpContext.Request.ServerVariables for both handled and unhandled exceptions
           if ((context2 == null) || (!_RaiseErrorSignal(e, context2) && !_IsFiltered(e, context2)))
           {
            _LogException(e, context2);
           }
       }
   }

   private static bool _IsFiltered(System.Exception e, System.Web.HttpContext context)
   {
       if (_config == null)
       {
           _config = (context.GetSection("elmah/errorFilter") as ErrorFilterConfiguration) ?? new ErrorFilterConfiguration();
       }
       var context2 = new ErrorFilterModule.AssertionHelperContext((System.Exception)e, context);
       return _config.Assertion.Test(context2);
   }

   private static void _LogException(System.Exception e, System.Web.HttpContext context)
   {
       ErrorLog.GetDefault((System.Web.HttpContext)context).Log(new Elmah.Error((System.Exception)e, (System.Web.HttpContext)context));
   }


   private static bool _RaiseErrorSignal(System.Exception e, System.Web.HttpContext context)
   {
       var signal = ErrorSignal.FromContext((System.Web.HttpContext)context);
       if (signal == null)
       {
           return false;
       }
       signal.Raise((System.Exception)e, (System.Web.HttpContext)context);
       return true;
   }
}

Now, in your filter config you want to do something like this:

    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        //These filters should go at the end of the pipeline, add all error handlers before
        filters.Add(new ElmahMVCErrorFilter());
    }

Notice that I left a comment there to remind people that if they want to add a global filter that will actually handle the exception it should go BEFORE this last filter, otherwise you run into the case where the unhandled exception will be ignored by the ElmahMVCErrorFilter because it hasn't been handled and it should be loged by the Elmah module but then the next filter marks the exception as handled and the module ignores it, resulting on the exception never making it into elmah.

Now, make sure the appsettings for elmah in your webconfig look something like this:

<add key="elmah.mvc.disableHandler" value="false" /> <!-- This handles elmah controller pages, if disabled elmah pages will not work -->
<add key="elmah.mvc.disableHandleErrorFilter" value="true" /> <!-- This uses the default filter for elmah, set to disabled to use our own -->
<add key="elmah.mvc.requiresAuthentication" value="false" /> <!-- Manages authentication for elmah pages -->
<add key="elmah.mvc.allowedRoles" value="*" /> <!-- Manages authentication for elmah pages -->
<add key="elmah.mvc.route" value="errortracking" /> <!-- Base route for elmah pages -->

The important one here is "elmah.mvc.disableHandleErrorFilter", if this is false it will use the handler inside elmah.mvc that will actually handle the exception by using the default HandleErrorHandler that will ignore your customError settings

This setup allows you to set your own ErrorHandler tags in classes and views, while still loging those errors through the ElmahMVCErrorFilter, adding a customError configuration to your web.config through the elmah module, even writing your own Error Handlers. The only thing you need to do is remember to not add any filters that will actually handle the error before the elmah filter we've written. And I forgot to mention: no duplicates in elmah.

http://en.wikipedia.org/wiki/Division_by_zero

http://en.wikipedia.org/wiki/Unix_signal#SIGFPE

This should give you a really good idea. Since a modulus is, in its basic sense, division with a remainder, something % 0 IS division by zero and as such, will trigger a SIGFPE being thrown.

ApplicationContextAware Interface ,the current application context, through which you can invoke the spring container services. We can get current applicationContext instance injected by below method in the class

public void setApplicationContext(ApplicationContext context) throws BeansException.

You can store the size somewhere, or you can have a struct with a special value set that you use as a sentinel, the same way that '\0' indicates the end of a string.

This question showed up when I was searching for a fast way to use git builtin way to locate differences. My solution criteria:

• Fast startup, needed builtin options
• Can handle many formats easily, xml, different programming languages
• Quickly identify small code changes in big textfiles

I found this answer to get color in git.

To get side by side diff instead of line diff I tweaked mb14's excellent answer on this question with the following parameters:

$ git diff --word-diff-regex="[A-Za-z0-9. ]|[^[:space:]]"

If you do not like the extra [- or {+ the option --word-diff=color can be used.

$ git diff --word-diff-regex="[A-Za-z0-9. ]|[^[:space:]]" --word-diff=color

That helped to get proper comparison with both json and xml text and java code.

In summary the --word-diff-regex options has a helpful visibility together with color settings to get a colorized side by side source code experience compared to the standard line diff, when browsing through big files with small line changes.

You could use a C function getaddrinfo() to get the numerical address - both ipv4 and ipv6. See the example code here

As far as I understand, the question is NOT about recursion. We can easily call main method of another class in your class. Following example illustrates static and calling by object. Note omission of word static in Class2

class Class1{
    public static void main(String[] args) {
        System.out.println("this is class 1");
    }    
}

class Class2{
    public void main(String[] args) {
        System.out.println("this is class 2");
    }    
}

class MyInvokerClass{
    public static void main(String[] args) {

        System.out.println("this is MyInvokerClass");
        Class2 myClass2 = new Class2();
        Class1.main(args);
        myClass2.main(args);
    }    
}

Output Should be:

this is wrapper class

this is class 1

this is class 2

use the min-height property. min-height:20px;

In short:

someValues.forEach((element) => {
    console.log(element);
});

If you care about index, then second parameter can be passed to receive the index of current element:

someValues.forEach((element, index) => {
    console.log(`Current index: ${index}`);
    console.log(element);
});

Refer here to know more about Array of ES6: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array

Use the -1 option (note this is a "one" digit, not a lowercase letter "L"), like this:

ls -1a

First, though, make sure your ls supports -1. GNU coreutils (installed on standard Linux systems) and Solaris do; but if in doubt, use man ls or ls --help or check the documentation. E.g.:

$ man ls
...
       -1     list one file per line.  Avoid '\n' with -q or -b

This works for me:

var result = $('#SubjectID option')
            .filter(function () 
             { return $(this).html() == "English"; }).val();

The result variable will return the index of the matched text value. Now I will just set it using it's index:

$('#SubjectID').val(result);

I know this is old as dirt but it ranked pretty high in google.

The problem with the solution maddy implemented (in response to rahul) to maintain the use of a While...Wend loop has some drawbacks

In the example given

num = 0
While num < 10
  If status = "Fail" Then
    num = 10
  End If
  num = num + 1
Wend

After status = "Fail" num will actually equal 11. The loop didn't end on the fail condition, it ends on the next test. All of the code after the check still processed and your counter is not what you might have expected it to be.

Now depending on what you are all doing in your loop it may not matter, but then again if your code looked something more like:

num = 0
While num < 10
  If folder = "System32" Then
    num = 10
  End If
  RecursiveDeleteFunction folder
  num = num + 1
Wend

Using Do While or Do Until allows you to stop execution of the loop using Exit Do instead of using trickery with your loop condition to maintain the While ... Wend syntax. I would recommend using that instead.

<div ng-controller="ExampleController">

   $scope.data = {
    model: null,

      {id: '3', name: 'Option C'}
    ]
   };
}]);

SELECT COALESCE(IF(myColumn = 1,COUNT(DISTINCT NumberColumn),NULL),0) column1,
COALESCE(CASE WHEN myColumn = 1 THEN COUNT(DISTINCT NumberColumn) ELSE NULL END,0) AS column2
FROM AD_CurrentView

The easiest way that I found for adding a column to a DataFrame was to use the "add" function. Here's a snippet of code, also with the output to a CSV file. Note that including the "columns" argument allows you to set the name of the column (which happens to be the same as the name of the np.array that I used as the source of the data).

#  now to create a PANDAS data frame
df = pd.DataFrame(data = FF_maxRSSBasal, columns=['FF_maxRSSBasal'])
# from here on, we use the trick of creating a new dataframe and then "add"ing it
df2 = pd.DataFrame(data = FF_maxRSSPrism, columns=['FF_maxRSSPrism'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = FF_maxRSSPyramidal, columns=['FF_maxRSSPyramidal'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = deltaFF_strainE22, columns=['deltaFF_strainE22'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = scaled, columns=['scaled'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = deltaFF_orientation, columns=['deltaFF_orientation'])
df = df.add( df2, fill_value=0 )
#print(df)
df.to_csv('FF_data_frame.csv')

You can use below code to get the batch of list.

Iterable<List<T>> batchIds = Iterables.partition(list, batchSize);

You need to import Google Guava library to use above code.

There are new features added. But, you will have to see if it is worth the upgrade. Some good improvements in Management Studio 2008 though, especially the intellisense for the Query Editor.

Well, you can use a regular expression to find the cases where "Milan" isn't followed by "Vasic":

Milan(?! Vasic)

and replace that by the full name:

String.replaceAll("Milan(?! Vasic)", "Milan Vasic")

The (?!...) part is a negative lookahead which ensures that whatever matches isn't followed by the part in parentheses. It doesn't consume any characters in the match itself.

Alternatively, you can simply insert (well, technically replacing a zero-width match) the last name after the first name, unless it's followed by the last name already. This looks similar, but uses a positive lookbehind as well:

(?<=Milan)(?! Vasic)

You can replace this by just " Vasic" (note the space at the start of the string):

String.replaceAll("(?<=Milan)(?! Vasic)", " Vasic")

You can try those things out here for example.

If the script is short and is meant to be embedded inside your script and you are running under bash shell and also bash shell is available on the remote side, you may use declare to transfer local context to remote. Define variables and functions containing the state that will be transferred to the remote. Define a function that will be executed on the remote side. Then inside a here document read by bash -s you can use declare -p to transfer the variable values and use declare -f to transfer function definitions to the remote.

Because declare takes care of the quoting and will be parsed by the remote bash, the variables are properly quoted and functions are properly transferred. You may just write the script locally, usually I do one long function with the work I need to do on the remote side. The context has to be hand-picked, but the following method is "good enough" for any short scripts and is safe - should properly handle all corner cases.

somevar="spaces or other special characters"
somevar2="!@#$%^"
another_func() {
    mkdir -p "$1"
}
work() {
    another_func "$somevar"
    touch "$somevar"/"$somevar2"
}
ssh user@server 'bash -s' <<EOT
$(declare -p somevar somevar2)    # transfer variables values
$(declare -f work another_func)   # transfer function definitions
work                              # call the function
EOT

The answer from Shivam Kotwalia works perfectly. However, the object is imported as a byte type. Sometimes you may need it as a string for performing REGEX or something like that.

I recommend the following code (two lines from Shivam Kotwalia's answer) :

import textract

text = textract.process("path/to/file.extension")
text = text.decode("utf-8") 

The last line will convert the object text to a string.

As @Agent_9191 and @partick mentioned you should use

$('tbody :visible').highlight(myArray[i]); // works for all children of tbody that are visible

or

$('tbody:visible').highlight(myArray[i]); // works for all visible tbodys

Additionally, since you seem to be applying a class to the highlighted words, instead of using jquery to alter the background for all matched highlights, just create a css rule with the background color you need and it gets applied directly once you assign the class.

.highlight { background-color: #FFFF88; }

Ud_an's solution with updated API's

Note: LatLng class is part of Google Play Services.

Mandatory:

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

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

Update: If you have target SDK 23 and above, make sure you take care of runtime permission for location.

public LatLng getLocationFromAddress(Context context,String strAddress) {

    Geocoder coder = new Geocoder(context);
    List<Address> address;
    LatLng p1 = null;

    try {
        // May throw an IOException
        address = coder.getFromLocationName(strAddress, 5);
        if (address == null) {
            return null;
        }

        Address location = address.get(0);
        p1 = new LatLng(location.getLatitude(), location.getLongitude() );

    } catch (IOException ex) {

        ex.printStackTrace();
    }

    return p1;
}

I was also facing the same issue with Postman for multipart. I fixed it by doing the following steps:

• Do not select Content-Type in the Headers section.
• In Body tab of Postman you should select form-data and select file type.

It worked for me.

I'd recommend reading the header directly from the driver, not through Spark. Two reasons for this: 1) It's a single line. There's no advantage to a distributed approach. 2) We need this line in the driver, not the worker nodes.

It goes something like this:

// Ridiculous amount of code to read one line.
val uri = new java.net.URI(filename)
val conf = sc.hadoopConfiguration
val fs = hadoop.fs.FileSystem.get(uri, conf)
val path = new hadoop.fs.Path(filename)
val stream = fs.open(path)
val source = scala.io.Source.fromInputStream(stream)
val header = source.getLines.head

Now when you make the RDD you can discard the header.

val csvRDD = sc.textFile(filename).filter(_ != header)

Then we can make an RDD from one column, for example:

val idx = header.split(",").indexOf(columnName)
val columnRDD = csvRDD.map(_.split(",")(idx))

What I did was download my sql dump in a "db-dump" folder, and mounted it:

mysql:
 image: mysql:5.6
 environment:
   MYSQL_ROOT_PASSWORD: pass
 ports:
   - 3306:3306
 volumes:
   - ./db-dump:/docker-entrypoint-initdb.d

When I run docker-compose up for the first time, the dump is restored in the db.

similar to the rest, but more specific:

    table.borderless td,table.borderless th{
     border: none !important;
}

Use the standard XPath function contains().

Function: boolean contains(string, string)

The contains function returns true if the first argument string contains the second argument string, and otherwise returns false

To handle the possibility of int, float, and empty string values, I'd use a combination of a list comprehension, dictionary comprehension, along with conditional expressions, as shown:

dicts = [{'a': '1' , 'b': '' , 'c': '3.14159'},
         {'d': '4' , 'e': '5' , 'f': '6'}]

print [{k: int(v) if v and '.' not in v else float(v) if v else None
            for k, v in d.iteritems()}
               for d in dicts]

# [{'a': 1, 'c': 3.14159, 'b': None}, {'e': 5, 'd': 4, 'f': 6}]

However dictionary comprehensions weren't added to Python 2 until version 2.7. It can still be done in earlier versions as a single expression, but has to be written using the dict constructor like the following:

# for pre-Python 2.7

print [dict([k, int(v) if v and '.' not in v else float(v) if v else None]
            for k, v in d.iteritems())
                for d in dicts]

# [{'a': 1, 'c': 3.14159, 'b': None}, {'e': 5, 'd': 4, 'f': 6}]

Note that either way this creates a new dictionary of lists, instead of modifying the original one in-place (which would need to be done differently).

I used andrew joslin's answer, which works great but triggered an angular route change, which created a jumpy looking scroll for me. If you want to avoid triggering a route change,

myApp.directive('scrollOnClick', function() {
  return {
    restrict: 'A',
    link: function(scope, $elm, attrs) {
      var idToScroll = attrs.href;
      $elm.on('click', function(event) {
        event.preventDefault();
        var $target;
        if (idToScroll) {
          $target = $(idToScroll);
        } else {
          $target = $elm;
        }
        $("body").animate({scrollTop: $target.offset().top}, "slow");
        return false;
      });
    }
  }
});

Change the headers in .htaccess

BrowserMatch MSIE ie
Header set X-UA-Compatible "IE=Edge,chrome=1" env=ie

Found the solution to this problem here: https://github.com/h5bp/html5-boilerplate/issues/378

If

(1) you have a _Layout.cshtml view like this

<html>
    <body>
        @RenderBody()

    </body>
    <script type="text/javascript" src="~/lib/layout.js"></script>
    @RenderSection("scripts", required: false)
</html>

(2) you have Contacts.cshtml

@section Scripts{
    <script type="text/javascript" src="~/lib/contacts.js"></script>

}
<div class="row">
    <div class="col-md-6 col-md-offset-3">
        <h2>    Contacts</h2>
    </div>
</div>

(3) you have About.cshtml

<div class="row">
    <div class="col-md-6 col-md-offset-3">
        <h2>    Contacts</h2>
    </div>
</div>

On you layout page, if required is set to false "@RenderSection("scripts", required: false)", When page renders and user is on about page, the contacts.js doesn't render.

    <html>
        <body><div>About<div>             
        </body>
        <script type="text/javascript" src="~/lib/layout.js"></script>
    </html>

if required is set to true "@RenderSection("scripts", required: true)", When page renders and user is on ABOUT page, the contacts.js STILL gets rendered.

<html>
    <body><div>About<div>             
    </body>
    <script type="text/javascript" src="~/lib/layout.js"></script>
    <script type="text/javascript" src="~/lib/contacts.js"></script>
</html>

IN SHORT, when set to true, whether you need it or not on other pages, it will get rendered anyhow. If set to false, it will render only when the child page is rendered.

.subscribe(data => {   
            console.log(data);
            let body:string = JSON.parse(data['_body']);`

if you want integer x value change if 1 to 0 and if 0 to 1 you can use (x + 1) % 2

If you pass a string that is case-insensitive into LINQ-to-SQL it will get passed into the SQL unchanged and the comparison will happen in the database. If you want to do case-insensitive string comparisons in the database all you need to to do is create a lambda expression that does the comparison and the LINQ-to-SQL provider will translate that expression into a SQL query with your string intact.

For example this LINQ query:

from user in Users
where user.Email == "[email protected]"
select user

gets translated to the following SQL by the LINQ-to-SQL provider:

SELECT [t0].[Email]
FROM [User] AS [t0]
WHERE [t0].[Email] = @p0
-- note that "@p0" is defined as nvarchar(11)
-- and is passed my value of "[email protected]"

As you can see, the string parameter will be compared in SQL which means things ought to work just the way you would expect them to.

I use regexp:

str =  'Write a program that extracts from a given text all palindromes, e.g. "ABBA", "lamal", "exe".';

var strNew = str.match(/\w+/g);

// Output: ["Write", "a", "program", "that", "extracts", "from", "a", "given", "text", "all", "palindromes", "e", "g", "ABBA", "lamal", "exe"]

You should use this code in your java file.

Random r = new Random();
                    int randomNumber = r.nextInt(100);
                    tv.setText(String.valueOf(randomNumber));

I wouldn't. I would use an ArrayList or a sorted collection with a Comparator. Sorting a LinkedList is about the most inefficient procedure I can think of.

use $BASHPID or $$

See the [manual][1] for more information, including differences between the two.

TL;DRTFM

• $$ Expands to the process ID of the shell.
  • In a () subshell, it expands to the process ID of the invoking shell, not the subshell.
• $BASHPID Expands to the process ID of the current Bash process (new to bash 4).
  • In a () subshell, it expands to the process ID of the subshell [1]: http://www.gnu.org/software/bash/manual/bashref.html#Bash-Variables

Well, if you're reading the data in as a list, just do np.array(map(float, list_of_strings)) (or equivalently, use a list comprehension). (In Python 3, you'll need to call list on the map return value if you use map, since map returns an iterator now.)

However, if it's already a numpy array of strings, there's a better way. Use astype().

import numpy as np
x = np.array(['1.1', '2.2', '3.3'])
y = x.astype(np.float)

You could do it this way:

res.status(400).json(json_response);

This will set the HTTP status code to 400, it works even in express 4.

A pt is 1/72th of an inch and is a useless measure for anything that is rendered on a device which doesn't calculate the DPI correctly. This makes it a reasonable choice for printing and a dreadful choice for use on screen.

A px is a pixel, which will map on to a screen pixel in most cases.

CSS provides a bunch of other units, and which one you should choose depends on what you are setting the size of.

A pixel is great if you need to size something to match an image, or if you want a thin border.

Percentages are great for font sizes as, if you use them consistently, you get font sizes proportional to the user's preference.

Ems are great when you want an element to size itself based on the font size (so a paragraph might get wider if the font size is larger)

… and so on.

use array_keys() to get an array of all the unique keys.

Note that an array with named keys like your $arr can also be accessed with numeric indexes, like $arr[0].

I did it using below steps:

1. git reset --hard <commit key of the pull request>
2. Did my changes in code I wanted to do
3. git add
4. git commit --amend
5. git push -f origin <name of the remote branch of pull request>

Let's assume that your iframe id= myIframe

here is the code:

<script>
window.setInterval("reloadIFrame();", 30000);
function reloadIFrame() {
 document.getElementById("myIframe").src="YOUR_PAGE_URL_HERE";
}
</script>

I'm having some luck with VisualPHPUnit, and it does helpfully show output, among other things.

class TestHello extends PHPUnit_Framework_TestCase 
{
    public function test_Hello() 
    {
        print "hello world";
    }
}

You can do it without specifying column types

df = data.frame(matrix(vector(), 0, 3,
                dimnames=list(c(), c("Date", "File", "User"))),
                stringsAsFactors=F)

I'm guessing you're using jQuery.get or some other jQuery ajax function to load the modal. You can show the indicator before the ajax call, and hide it when the ajax completes. Something like

$('#indicator').show();
$('#someModal').get(anUrl, someData, function() { $('#indicator').hide(); });

adding to scotty's answer:

Option 1: Either include this in your JS file:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular-route.min.js"></script>

Option 2: or just use the URL to download 'angular-route.min.js' to your local.

and then (whatever option you choose) add this 'ngRoute' as dependency.

explained: var app = angular.module('myapp', ['ngRoute']);

Cheers!!!

X.each_with_index do |item, index|

You're looking for the indexOf function:

if (str.indexOf("are") >= 0){//Do stuff}

The suggested solutions could be optimized using commons.io, handling the error stream, and using Exceptions. I would suggest to wrap like this for use in Java 8 or later:

public static List<String> execute(final String command) throws ExecutionFailedException, InterruptedException, IOException {
    try {
        return execute(command, 0, null, false);
    } catch (ExecutionTimeoutException e) { return null; } /* Impossible case! */
}

public static List<String> execute(final String command, final long timeout, final TimeUnit timeUnit) throws ExecutionFailedException, ExecutionTimeoutException, InterruptedException, IOException {
    return execute(command, 0, null, true);
}

public static List<String> execute(final String command, final long timeout, final TimeUnit timeUnit, boolean destroyOnTimeout) throws ExecutionFailedException, ExecutionTimeoutException, InterruptedException, IOException {
    Process process = new ProcessBuilder().command("bash", "-c", command).start();
    if(timeUnit != null) {
        if(process.waitFor(timeout, timeUnit)) {
            if(process.exitValue() == 0) {
                return IOUtils.readLines(process.getInputStream(), StandardCharsets.UTF_8);
            } else {
                throw new ExecutionFailedException("Execution failed: " + command, process.exitValue(), IOUtils.readLines(process.getInputStream(), StandardCharsets.UTF_8));

Adding to @Mike's answer. I also needed double tap to restore the image to the original dimensions when first viewed. So I added a whole heap of "orig..." instance variables and added the SimpleOnGestureListener which did the trick.

Although fractional pixels may appear to round up on individual elements (as @SkillDrick demonstrates very well) it's important to know that the fractional pixels are actually respected in the actual box model.

This can best be seen when elements are stacked next to (or on top of) each other; in other words, if I were to place 400 0.5 pixel divs side by side, they would have the same width as a single 200 pixel div. If they all actually rounded up to 1px (as looking at individual elements would imply) we'd expect the 200px div to be half as long.

This can be seen in this runnable code snippet:

Using Visual Studio

1. Attach a debugger to the process (e.g. start with debugging or Debug > Attach to process)
2. While debugging, show the Modules window (Debug > Windows > Modules)

This gives details about each assembly, app domain and has a few options to load symbols (i.e. pdb files that contain debug information).

Using Process Explorer

If you want an external tool you can use the Process Explorer (freeware, published by Microsoft)

Click on a process and it will show a list with all the assemblies used. The tool is pretty good as it shows other information such as file handles etc.

Programmatically

Check this SO question that explains how to do it.

Follow up to Eonil's answer related to project level settings. With the target selected and the Build Settings tab selected, there may be no listing under Search Paths for Header Search Paths. In this case, you can change to "All" from "Basic" in the search bar and Header Search Paths will show up in the Search Paths section.

Try like

HTML in PHP :

echo "<a href='".$link_address."'>Link</a>";

Or even you can try like

echo "<a href='$link_address'>Link</a>";

Or you can use PHP in HTML like

PHP in HTML :

<a href="<?php echo $link_address;?>"> Link </a>

The accepted answer offers a solution which requires changing of the underlying data frame. This is not necessary. One can also simply factorise within the aes() call directly or create a vector for that instead.

This is certainly not much different than user Drew Steen's answer, but with the important difference of not changing the original data frame.

level_order <- c('virginica', 'versicolor', 'setosa') #this vector might be useful for other plots/analyses

ggplot(iris, aes(x = factor(Species, level = level_order), y = Petal.Width)) + geom_col()

or

level_order <- factor(iris$Species, level = c('virginica', 'versicolor', 'setosa'))

ggplot(iris, aes(x = level_order, y = Petal.Width)) + geom_col()

or
directly in the aes() call without a pre-created vector:

ggplot(iris, aes(x = factor(Species, level = c('virginica', 'versicolor', 'setosa')), y = Petal.Width)) + geom_col()

For anybody that wants a quick solution here is how I removed Decimal from my queries in Django

total_development_cost_var = process_assumption_objects.values('total_development_cost').aggregate(sum_dev = Sum('total_development_cost', output_field=FloatField()))
total_development_cost_var = list(total_development_cost_var.values())

• Step 1: use , output_field=FloatField() in you r query
• Step 2: use list eg list(total_development_cost_var.values())

Hope it helps

Try this:

SELECT
    salary,
    employeeid
FROM
    employees
ORDER BY
    salary DESC
LIMIT 2

Then just get the second row.

this is just as a side note, but generally what you want to do is keep size on the Session and ViewState small. I generally just store IDs and small amounts of packets in Session and ViewState.

for instance if you want to pass large chunks of data from one page to another, you can store an ID in the querystring and use that ID to either get data from a database or a file.

PS: but like I said, this might be totally unrelated to your query :)

As this is the top search on Google for converting a list of lists into a Numpy array, I'll offer the following despite the question being 4 years old:

>>> x = [[1, 2], [1, 2, 3], [1]]
>>> y = numpy.hstack(x)
>>> print(y)
[1 2 1 2 3 1]

When I first thought of doing it this way, I was quite pleased with myself because it's soooo simple. However, after timing it with a larger list of lists, it is actually faster to do this:

>>> y = numpy.concatenate([numpy.array(i) for i in x])
>>> print(y)
[1 2 1 2 3 1]

Note that @Bastiaan's answer #1 doesn't make a single continuous list, hence I added the concatenate.

Anyway...I prefer the hstack approach for it's elegant use of Numpy.

I think your code is trying to "divide by zero" or "divide by NaN". If you are aware of that and don't want it to bother you, then you can try:

import numpy as np
np.seterr(divide='ignore', invalid='ignore')

For more details see:

• http://docs.scipy.org/doc/numpy/reference/generated/numpy.seterr.html

The syntax you used is problematic. In html, an attribute (ex: style) has a value delimited by double quotes. In that case, the value of the style attribute is a css list of selectors. Try this:

<h2 style="text-align:center; font-family:tahoma">TITLE</h2>

For those of us who this above valid solution didnt work, there's another workaround here

 searchView.setOnQueryTextFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View view, boolean isFocused) {
            if(!isFocused)
            {
                Toast.makeText(MainActivity.this,"not focused",Toast.LENGTH_SHORT).show();

            }
        }
    });

Starting in ios 6 you can set an attributed string in the UILabel:

NSString *labelText = @"some text"; 
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:labelText];
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
[paragraphStyle setLineSpacing:40];
[attributedString addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, [labelText length])];
cell.label.attributedText = attributedString ;

To create icon you can use Glyphicon in Bootstrap:

<a href="#" class="btn btn-info btn-sm">
    <span class="glyphicon glyphicon-menu-hamburger"></span>
</a>

And then control size of icon in css:

.glyphicon-menu-hamburger {
  font-size: npx;
}

it saves your .bat file to "Appdata of current user" ,if it does not exist and remove the attributes and after that set the "hidden" attributes to file after writing your cmd code and run it silently and capture all output saves it to file so if u wanna save all output of cmd to file just add your like this

code > C:\Users\Lenovo\Desktop\output.txt

just replace word "code" with your .bat file code or command and after that the directory of output file I found one code recently after searching alot if u wanna run .bat file in vb or c# or simply just add this in the same manner in which i have written

Try this code :

1. If you just want to inflate your layout :

View view = LayoutInflater.from(context).inflate(R.layout.your_xml_layout,null); // Code for inflating xml layout_x000D_
RelativeLayout item = view.findViewById(R.id.item);   

2. If you want to inflate your layout in container(parent layout) :

LinearLayout parent = findViewById(R.id.container);        //parent layout._x000D_
View view = LayoutInflater.from(context).inflate(R.layout.your_xml_layout,parent,false); _x000D_
RelativeLayout item = view.findViewById(R.id.item);       //initialize layout & By this you can also perform any event._x000D_
parent.addView(view);             //adding your inflated layout in parent layout.

The answer is NO.

The reason is provided in the flexbox specification:

6. Flex Lines

In a multi-line flex container, the cross size of each line is the minimum size necessary to contain the flex items on the line.

In other words, when there are multiple lines in a row-based flex container, the height of each line (the "cross size") is the minimum height necessary to contain the flex items on the line.

Equal height rows, however, are possible in CSS Grid Layout:

• Equal height rows in CSS Grid Layout

Otherwise, consider a JavaScript alternative.

Here is the answer for those of you who need a Boostrap 3 solution.

In bootstrap 3 use 'shown.bs.tab' instead of 'shown' in the next line

// tab
$('#rowTab a:first').tab('show');

$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
//show selected tab / active
 console.log ( $(e.target).attr('id') );
});

This Should work Making it Round to 2 Point

       int a=53214
       parseFloat(Math.round(a* 100) / 100).toFixed(2);

This question has been pretty well answered, but I'm taking the liberty of adding a javascript solution. Just give the element that you want to 'expand' the id footerspacerdiv, and this javascript snippet will expand that div until the page takes up the full height of the browser window.

It works based on the observation that, when a page is less than the full height of the browser window, document.body.scrollHeight is equal to document.body.clientHeight. The while loop increases the height of footerspacerdiv until document.body.scrollHeight is greater than document.body.clientHeight. At this point, footerspacerdiv will actually be 1 pixel too tall, and the browser will show a vertical scroll bar. So, the last line of the script reduces the height of footerspacerdiv by one pixel to make the page height exactly the height of the browser window.

By placing footerspacerdiv just above the 'footer' of the page, this script can be used to 'push the footer down' to the bottom of the page, so that on short pages, the footer is flush with the bottom of the browser window.

<script>    
//expand footerspacer div so that footer goes to bottom of page on short pages        
  var objSpacerDiv=document.getElementById('footerspacer');          
  var bresize=0;   

  while(document.body.scrollHeight<=document.body.clientHeight) {
    objSpacerDiv.style.height=(objSpacerDiv.clientHeight+1)+"px";
    bresize=1;
  }             
  if(bresize) { objSpacerDiv.style.height=(objSpacerDiv.clientHeight-1)+"px"; }               
 </script>

Cellpadding is the amount of space between the outer edges of the table cell and the content of the cell.

Cellspacing is the amount of space in between the individual table cells.

Try this out:

$url = 'http://techcrunch.com/startups/'; $url = str_replace(array('http://', 'https://'), '', $url); 

EDIT:

Or, a simple way to always remove the protocol:

$url = 'https://www.google.com/'; $url = preg_replace('@^.+?\:\/\/@', '', $url); 

In that table in SQL Server, specify the default value of that column to be CURRENT_TIMESTAMP. The datatype of that column may be datetime or datetime2.

e.g.

Create Table Student
(
  Name varchar(50),
  DateOfAddmission datetime default CURRENT_TIMESTAMP
);

This works perfectly for me in Bootstrap 4.

<div class="form-row align-items-center">
   <div class="col-md-2">
     <label for="FirstName" style="margin-bottom:0rem !important;">First Name</label>
 </div>
 <div class="col-md-10">
    <input type="text" id="FirstName" name="FirstName" class="form-control" val=""/>
  /div>
</div>

The job of the DispatcherServlet is to take an incoming URI and find the right combination of handlers (generally methods on Controller classes) and views (generally JSPs) that combine to form the page or resource that's supposed to be found at that location.

I might have

• a file /WEB-INF/jsp/pages/Home.jsp

• and a method on a class

  @RequestMapping(value="/pages/Home.html")
  private ModelMap buildHome() {
      return somestuff;
  }
  

The Dispatcher servlet is the bit that "knows" to call that method when a browser requests the page, and to combine its results with the matching JSP file to make an html document.

How it accomplishes this varies widely with configuration and Spring version.

There's also no reason the end result has to be web pages. It can do the same thing to locate RMI end points, handle SOAP requests, anything that can come into a servlet.

After t.thielemans' answer, I worked that just

=VLOOKUP(A1, B:C, 2, FALSE) 

works fine and does what I wanted, except that it returns #N/A for non-matches; so it is suitable for the case where it is known that the value definitely exists in the look-up column.

Edit (based on t.thielemans' comment):

To avoid #N/A for non-matches, do:

=IFERROR(VLOOKUP(A1, B:C, 2, FALSE), "No Match")

If you mean using a literal, you simply have to create a binary string:

insert into Files (FileId, FileData) values (1, 0x010203040506)

And you will have a record with a six byte value for the FileData field.

You indicate in the comments that you want to just specify the file name, which you can't do with SQL Server 2000 (or any other version that I am aware of).

You would need a CLR stored procedure to do this in SQL Server 2005/2008 or an extended stored procedure (but I'd avoid that at all costs unless you have to) which takes the filename and then inserts the data (or returns the byte string, but that can possibly be quite long).

In regards to the question of only being able to get data from a SP/query, I would say the answer is yes, because if you give SQL Server the ability to read files from the file system, what do you do when you aren't connected through Windows Authentication, what user is used to determine the rights? If you are running the service as an admin (God forbid) then you can have an elevation of rights which shouldn't be allowed.

This seems to happen when there's a generic problem with your data source that it isn't handling.

In my case I had inserted a bunch of data, the indexes had become corrupt on the table, they needed rebuilding. I found a script to rebuild them all, seemed to fix it. To find the error I ran the same query on the database - one that had worked 100+ times previously.

I would add one more thing to Marc's answer: The memberOf attribute can't contain wildcards, so you can't say something like "memberof=CN=SPS*", and expect it to find all groups that start with "SPS".

This codifies @Sérgio and @unutbu's answers. It will "just work" with either a pytz.timezone object or an IANA Time Zone string.

def make_tz_aware(dt, tz='UTC', is_dst=None):
    """Add timezone information to a datetime object, only if it is naive."""
    tz = dt.tzinfo or tz
    try:
        tz = pytz.timezone(tz)
    except AttributeError:
        pass
    return tz.localize(dt, is_dst=is_dst) 

This seems like what datetime.localize() (or .inform() or .awarify()) should do, accept both strings and timezone objects for the tz argument and default to UTC if no time zone is specified.

It would make for a handy function. Also, note I'm using STUFF instead of SUBSTRING.

create function str2uniq(@s varchar(50)) returns uniqueidentifier as begin
    -- just in case it came in with 0x prefix or dashes...
    set @s = replace(replace(@s,'0x',''),'-','')
    -- inject dashes in the right places
    set @s = stuff(stuff(stuff(stuff(@s,21,0,'-'),17,0,'-'),13,0,'-'),9,0,'-')
    return cast(@s as uniqueidentifier)
end

Try this for compatibility;

<script type="text/javascript">
        $(function() {
            setTimeout(function() {
                window.location.href = $('#myAnchor').attr("href");

            }, 1500);
        });
    </script>

When you add a click event, this returns the element that has been clicked. So you can just use this.id;

$(".test").click(function(){
   alert(this.id); 
});

The only difference between the RANK() and DENSE_RANK() functions is in cases where there is a “tie”; i.e., in cases where multiple values in a set have the same ranking. In such cases, RANK() will assign non-consecutive “ranks” to the values in the set (resulting in gaps between the integer ranking values when there is a tie), whereas DENSE_RANK() will assign consecutive ranks to the values in the set (so there will be no gaps between the integer ranking values in the case of a tie).

For example, consider the set {25, 25, 50, 75, 75, 100}. For such a set, RANK() will return {1, 1, 3, 4, 4, 6} (note that the values 2 and 5 are skipped), whereas DENSE_RANK() will return {1,1,2,3,3,4}.

This works for me!!!

When you specify window features, it will open in a new window

Just like :

window.open(url,"_blank","top=100,left=200,width=1000,height=500");

None of the other answers dealt with the case of using .children() or .find(">") to only search for immediate children of a parent element. So, I created a jsPerf test to find out, using three different ways to distinguish children.

As it happens, even when using the extra ">" selector, .find() is still a lot faster than .children(); on my system, 10x so.

So, from my perspective, there does not appear to be much reason to use the filtering mechanism of .children() at all.

Prior to PHP 5.3.6, the charset option was ignored. If you're running an older version of PHP, you must do it like this:

<?php

    $dbh = new PDO("mysql:$connstr",  $user, $password);

    $dbh -> exec("set names utf8");

?>

This has changed for android 4.4.2. .. you should look in the repository file and download https://dl-ssl.google.com/android/repository/repository-10.xml

1. android-sdk_r20.0.1-windows.zip ( I think that is actually windows specific tools)
2. android-19_r03.zip for all platform ( actual api) and store under platforms in #1

In manual install dir structure should look like

Now you have to..

1. download win SDK helper ( avd/SDK magr): https://dl.google.com/android/android-sdk_r20.0.1-windows.zip
2. actual sdk api https://dl-ssl.google.com/android/repository/android-20_r01.zip
3. samples https://dl-ssl.google.com/android/repository/samples-19_r05.zip
4. images : https://dl-ssl.google.com/android/repository/sys-img/x86/sys-img.xml e.g. https://dl-ssl.google.com/android/repository/sysimg_armv7a-18_r02.zip extract in : “Platforms > Android-4.4.2>"
5. platform-tools: https://dl-ssl.google.com/android/repository/platform-tools_r19.0.1-windows.zip
6. build-tools: create folder (build-tools at main sdk level) https://dl-ssl.google.com/android/repository/build-tools_r17-windows.zip
7. copy aapt.exe, aidl.exe and dr.bat to platform-tools folder.
8. you may download tools as well same way
9. source: https://dl-ssl.google.com/android/repository/sources-19_r02.zip

At this point you should have a working android installation.

If you don't want to reboot your can, a solution is to manually attach the debugger. In my case the application is launched but visual studio fails to connect to the iis. In Visual Studio 2019: Debug -> Attach to process -> filter by iis and select iisexpress.exe
