to solve the error like this one: "list object is not callable in python" even you are changing the variable name then please restart the kernel in Python Jutyter Notebook if you are using it or simply restart the IDE.

I hope this will work. Thank you!!!

If I understand you correctly, you're talking about doing a

svn merge -rn:n-1

to back out of an earlier commit, in which case, you're probably looking for

git revert

Couldn't you just have another sub that acts as a caller using module level variable(s) for the arguments you want to pass. For example...

Option Explicit
Public strMsg As String

Sub Scheduler()

    strMsg = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
    Application.OnTime Now + TimeValue("00:00:01"), "'Caller'"

End Sub

Sub Caller()

    Call aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa("It Works! " & strMsg)

End Sub

Sub aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(strMessage As String)

    MsgBox strMessage

End Sub

As mentioned by the top-voted answer, Martin Fowler discusses these distinctions in Mocks Aren't Stubs, and in particular the subheading The Difference Between Mocks and Stubs, so make sure to read that article.

Rather than focusing on how these things are different, I think it's more enlightening to focus on why these are distinct concepts. Each exists for a different purpose.

Fakes

A fake is an implementation that behaves "naturally", but is not "real". These are fuzzy concepts and so different people have different understandings of what makes things a fake.

One example of a fake is an in-memory database (e.g. using sqlite with the :memory: store). You would never use this for production (since the data is not persisted), but it's perfectly adequate as a database to use in a testing environment. It's also much more lightweight than a "real" database.

As another example, perhaps you use some kind of object store (e.g. Amazon S3) in production, but in a test you can simply save objects to files on disk; then your "save to disk" implementation would be a fake. (Or you could even fake the "save to disk" operation by using an in-memory filesystem instead.)

As a third example, imagine an object that provides a cache API; an object that implements the correct interface but that simply performs no caching at all but always returns a cache miss would be a kind of fake.

The purpose of a fake is not to affect the behavior of the system under test, but rather to simplify the implementation of the test (by removing unnecessary or heavyweight dependencies).

Stubs

A stub is an implementation that behaves "unnaturally". It is preconfigured (usually by the test set-up) to respond to specific inputs with specific outputs.

The purpose of a stub is to get your system under test into a specific state. For example, if you are writing a test for some code that interacts with a REST API, you could stub out the REST API with an API that always returns a canned response, or that responds to an API request with a specific error. This way you could write tests that make assertions about how the system reacts to these states; for example, testing the response your users get if the API returns a 404 error.

A stub is usually implemented to only respond to the exact interactions you've told it to respond to. But the key feature that makes something a stub is its purpose: a stub is all about setting up your test case.

Mocks

A mock is similar to a stub, but with verification added in. The purpose of a mock is to make assertions about how your system under test interacted with the dependency.

For example, if you are writing a test for a system that uploads files to a website, you could build a mock that accepts a file and that you can use to assert that the uploaded file was correct. Or, on a smaller scale, it's common to use a mock of an object to verify that the system under test calls specific methods of the mocked object.

Mocks are tied to interaction testing, which is a specific testing methodology. People who prefer to test system state rather than system interactions will use mocks sparingly if at all.

Test doubles

Fakes, stubs, and mocks all belong to the category of test doubles. A test double is any object or system you use in a test instead of something else. Most automated software testing involves the use of test doubles of some kind or another. Some other kinds of test doubles include dummy values, spies, and I/O blackholes.

Accessing batch parameters can be simple with %1, %2, ... %9 or also %*,
but only if the content is simple.

There is no simple way for complex contents like "&"^&, as it's not possible to access %1 without producing an error.

set  var=%1
set "var=%1"
set  var=%~1
set "var=%~1"

The lines expand to

set  var="&"&
set "var="&"&"
set  var="&"&
set "var="&"&"

And each line fails, as one of the & is outside of the quotes.

It can be solved with reading from a temporary file a remarked version of the parameter.

@echo off
SETLOCAL DisableDelayedExpansion

SETLOCAL
for %%a in (1) do (
    set "prompt="
    echo on
    for %%b in (1) do rem * #%1#
    @echo off
) > param.txt
ENDLOCAL

for /F "delims=" %%L in (param.txt) do (
  set "param1=%%L"
)
SETLOCAL EnableDelayedExpansion
set "param1=!param1:*#=!"
set "param1=!param1:~0,-2!"
echo %%1 is '!param1!'

The trick is to enable echo on and expand the %1 after a rem statement (works also with %2 .. %*).
So even "&"& could be echoed without producing an error, as it is remarked.

But to be able to redirect the output of the echo on, you need the two for-loops.

The extra characters * # are used to be safe against contents like /? (would show the help for REM).
Or a caret ^ at the line end could work as a multiline character, even in after a rem.

Then reading the rem parameter output from the file, but carefully.
The FOR /F should work with delayed expansion off, else contents with "!" would be destroyed.
After removing the extra characters in param1, you got it.

And to use param1 in a safe way, enable the delayed expansion.

There are two major categories of types in Java: primitive and reference. Variables declared of a primitive type store values; variables declared of a reference type store references.

String x = null;

In this case, the initialization statement declares a variables “x”. “x” stores String reference. It is null here. First of all, null is not a valid object instance, so there is no memory allocated for it. It is simply a value that indicates that the object reference is not currently referring to an object.

Disabling Use command-line client from the settings on IntelliJ Ultimate 14.0.3 works for me.

I checked IDEA's document, IDEA don't need a SVN client software anymore. see below description from https://www.jetbrains.com/idea/help/using-subversion-integration.html

=================================================================

Prerequisites

IntelliJ IDEA comes bundled with Subversion plugin. This plugin is turned on by default. If it is not, make sure that the plugin is enabled. IntelliJ IDEA's Subversion integration does not require a standalone Subversion client. All you need is an account in your Subversion repository. Subversion integration is enabled for the current project root or directory.

==================================================================

Another option is to update the Microsoft.AspnNet.Mvc NuGet package. Be careful, because NuGet update does not update the Web.Config. You should update all previous version numbers to updated number. For example if you update from asp.net MVC 4.0.0.0 to 5.0.0.0, then this should be replaced in the Web.Config:

    <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

C++ implementation with probably better performance than @Mohsen code. It uses a [0-6] range for the hue, avoiding the division and multiplication by 6. S and L range is [0,1]

void fromRGBtoHSL(float rgb[], float hsl[])
{
     const float maxRGB = max(rgb[0], max(rgb[1], rgb[2]));
     const float minRGB = min(rgb[0], min(rgb[1], rgb[2]));
     const float delta2 = maxRGB + minRGB;
     hsl[2] = delta2 * 0.5f;

     const float delta = maxRGB - minRGB;
     if (delta < FLT_MIN)
         hsl[0] = hsl[1] = 0.0f;
     else
     {
         hsl[1] = delta / (hsl[2] > 0.5f ? 2.0f - delta2 : delta2);
         if (rgb[0] >= maxRGB)
         {
             hsl[0] = (rgb[1] - rgb[2]) / delta;
             if (hsl[0] < 0.0f)
                 hsl[0] += 6.0f;
         }
         else if (rgb[1] >= maxRGB)
             hsl[0] = 2.0f + (rgb[2] - rgb[0]) / delta;
         else
             hsl[0] = 4.0f + (rgb[0] - rgb[1]) / delta;
     }
}

void fromHSLtoRGB(const float hsl[], float rgb[])
{
    if(hsl[1] < FLT_MIN)
        rgb[0] = rgb[1] = rgb[2] = hsl[2];
    else if(hsl[2] < FLT_MIN)
        rgb[0] = rgb[1] = rgb[2] = 0.0f;
    else
    {
        const float q = hsl[2] < 0.5f ? hsl[2] * (1.0f + hsl[1]) : hsl[2] + hsl[1] - hsl[2] * hsl[1];
        const float p = 2.0f * hsl[2] - q;
        float t[] = {hsl[0] + 2.0f, hsl[0], hsl[0] - 2.0f};

        for(int i=0; i<3; ++i)
        {
            if(t[i] < 0.0f)
                t[i] += 6.0f;
            else if(t[i] > 6.0f)
                t[i] -= 6.0f;

            if(t[i] < 1.0f)
                rgb[i] = p + (q - p) * t[i];
            else if(t[i] < 3.0f)
                rgb[i] = q;
            else if(t[i] < 4.0f)
                rgb[i] = p + (q - p) * (4.0f - t[i]);
            else
                rgb[i] = p;
          }
      }
}

You listen to the onerror event by assigning a function to window.onerror:

 window.onerror = function (msg, url, lineNo, columnNo, error) {
        var string = msg.toLowerCase();
        var substring = "script error";
        if (string.indexOf(substring) > -1){
            alert('Script Error: See Browser Console for Detail');
        } else {
            alert(msg, url, lineNo, columnNo, error);
        }   
      return false; 
  };

Let's say you have defined an empty array:

$myArr = array();

If you want to simply add an element, e.g. 'New Element to Array', write

$myArr[] = 'New Element to Array';

if you are calling the data from the database, below code will work fine

$sql = "SELECT $element FROM $table";
$query = mysql_query($sql);
if(mysql_num_rows($query) > 0)//if it finds any row
{
   while($result = mysql_fetch_object($query))
   {
      //adding data to the array
      $myArr[] = $result->$element;
   }
}

Tables are iffy (at least, in IE) when it comes to fixing heights and not wrapping text. I think you'll find that the only solution is to put the text inside a div element, like so:

td.container > div {_x000D_
    width: 100%;_x000D_
    height: 100%;_x000D_
    overflow:hidden;_x000D_
}_x000D_
td.container {_x000D_
    height: 20px;_x000D_
}

<table>_x000D_
    <tr>_x000D_
        <td class="container">_x000D_
            <div>This is a long line of text designed not to wrap _x000D_
                 when the container becomes too small.</div>_x000D_
        </td>_x000D_
    </tr>_x000D_
</table>

This way, the div's height is that of the containing cell and the text cannot grow the div, keeping the cell/row the same height no matter what the window size is.

A solution that nobody mentioned is use white-space: nowrap for the table and add overflow-x to the wrapper.

(http://jsfiddle.net/xc7jLuyx/11/)

CSS

.wrapper { overflow-x: auto; }
.wrapper table { white-space: nowrap }

HTML

<div class="wrapper">
    <table></table>
</div>

This is an ideal scenario if you don't want rows with multiple lines.
To add break lines you need to use <br/>.

You can pass the value back into the component by creating a reference variable on the select tag #device and passing it into the change handler onChange($event, device.value) should have the new value

<select [(ng-model)]="selectedDevice" #device (change)="onChange($event, device.value)">
    <option *ng-for="#i of devices">{{i}}</option>
</select>

onChange($event, deviceValue) {
    console.log(deviceValue);
}

Remove new line characters with SQL column data

Update a set  a.CityName=Rtrim(Ltrim(REPLACE(REPLACE(a.CityName,CHAR(10),' '),CHAR(13),' ')))
,a.postalZone=Rtrim(Ltrim(REPLACE(REPLACE(a.postalZone,CHAR(10),' '),CHAR(13),' ')))  
From tAddress a 
inner Join  tEmployees p  on a.AddressId =p.addressId 
Where p.MigratedID is not null and p.AddressId is not null AND
(REPLACE(REPLACE(a.postalZone,CHAR(10),'Y'),CHAR(13),'X') Like 'Y%' OR REPLACE(REPLACE(a.CityName,CHAR(10),'Y'),CHAR(13),'X') Like 'Y%')

The memory associated with arr is freed automatically when arr goes out of scope. It is either a local variable, or allocated statically, but it is not dynamically allocated.

A simple rule for you to follow is that you must only every call free() on a pointer that was returned by a call to malloc, calloc or realloc.

As mentioned in previous answers we cannot restrict user to select files for only given file formats. But it's really handy to use the accept tag on file attribute in html.

As for validation, we have to do it at the server side. We can also do it at client side in js but its not a foolproof solution. We must validate at server side.

For these requirements I really prefer struts2 Java web application development framework. With its built-in file upload feature, uploading files to struts2 based web apps is a piece of cake. Just mention the file formats that we would like to accept in our application and all the rest is taken care of by the core of framework itself. You can check it out at struts official site.

 $A = array('a' => 1, 'b' => 2, 'c' => 3);
 $B = array('c' => 4, 'd'=> 5);
 $C = array_merge_recursive($A, $B);
 $aWhere = array();
 foreach ($C as $k=>$v) {

    if (is_array($v)) {
        $aWhere[] = $k . ' in ('.implode(', ',$v).')';
    }
    else {
        $aWhere[] = $k . ' = ' . $v;
    }
 }
 $where = implode(' AND ', $aWhere);
 echo $where;

Convert the string to an integer base 16 then to hexadecimal.

print hex(int(string, base=16))

These are built-in functions.

http://docs.python.org/2/library/functions.html#int

Example

>>> string = 'AA'
>>> _int = int(string, base=16)
>>> _hex = hex(_int)
>>> print _int
170
>>> print _hex
0xaa
>>> 

You can use a Scanner for this. It's not clear what your exact requirements are, but here's an example that should be illustrative:

    Scanner sc = new Scanner(System.in).useDelimiter("\\s*");
    while (!sc.hasNext("z")) {
        char ch = sc.next().charAt(0);
        System.out.print("[" + ch + "] ");
    }

If you give this input:

123 a b c x   y   z

The output is:

[1] [2] [3] [a] [b] [c] [x] [y] 

So what happens here is that the Scanner uses \s* as delimiter, which is the regex for "zero or more whitespace characters". This skips spaces etc in the input, so you only get non-whitespace characters, one at a time.

Right click on project >> Click on properties >> Java Build Path >> Source >> Add Folder

Below is a solution from here

Sub stance()
Dim x As Long

For x = 1 To 10    
    Debug.Print x
Next

Debug.Print Now
Application.SendKeys "^g ^a {DEL}"    
End Sub

You can use os.sep:

>>> import os
>>> os.sep
'/'

There's always cmd. It may be less annoying if you have trouble quoting arguments to start-process:

cmd /c start /wait notepad

Or

notepad | out-host

This might not be the best way to do things, but should work:

 this.textBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
 this.textBox1.AutoCompleteSource = AutoCompleteSource.CustomSource;

private void textBox1_TextChanged(object sender, EventArgs e)
{
    TextBox t = sender as TextBox;
    if (t != null)
    {
        //say you want to do a search when user types 3 or more chars
        if (t.Text.Length >= 3)
        {
            //SuggestStrings will have the logic to return array of strings either from cache/db
            string[] arr = SuggestStrings(t.Text);

            AutoCompleteStringCollection collection = new AutoCompleteStringCollection();
            collection.AddRange(arr);

            this.textBox1.AutoCompleteCustomSource = collection;
        }
    }
}

I disagree with the document.write technique (see suggestion of Vahan Margaryan). I like document.getElementsByTagName('head')[0].appendChild(...) (see suggestion of Matt Ball), but there is one important issue: the script execution order.

Recently, I have spent a lot of time reproducing one similar issue, and even the well-known jQuery plugin uses the same technique (see src here) to load the files, but others have also reported the issue. Imagine you have JavaScript library which consists of many scripts, and one loader.js loads all the parts. Some parts are dependent on one another. Imagine you include another main.js script per <script> which uses the objects from loader.js immediately after the loader.js. The issue was that sometimes main.js is executed before all the scripts are loaded by loader.js. The usage of $(document).ready(function () {/*code here*/}); inside of main.js script does not help. The usage of cascading onload event handler in the loader.js will make the script loading sequential instead of parallel, and will make it difficult to use main.js script, which should just be an include somewhere after loader.js.

By reproducing the issue in my environment, I can see that **the order of execution of the scripts in Internet Explorer 8 can differ in the inclusion of the JavaScript*. It is a very difficult issue if you need include scripts that are dependent on one another. The issue is described in Loading Javascript files in parallel, and the suggested workaround is to use document.writeln:

document.writeln("<script type='text/javascript' src='Script1.js'></script>");
document.writeln("<script type='text/javascript' src='Script2.js'></script>");

So in the case of "the scripts are downloaded in parallel but executed in the order they're written to the page", after changing from document.getElementsByTagName('head')[0].appendChild(...) technique to document.writeln, I had not seen the issue anymore.

So I recommend that you use document.writeln.

UPDATED: If somebody is interested, they can try to load (and reload) the page in Internet Explorer (the page uses the document.getElementsByTagName('head')[0].appendChild(...) technique), and then compare with the fixed version used document.writeln. (The code of the page is relatively dirty and is not from me, but it can be used to reproduce the issue).

First, open Device Manager by searching for it in the Windows search bar.

Then, click ports and right click the port the Arduino is connected to. Then, go to Port settings → Advanced. Next, select any port that is not in use and is not the port the Arduino is currently connected to. Then click OK and unplug + replug your Arduino. This works most of the time with any Arduino board.

Extract all audio tracks / streams

This puts all audio into one file:

ffmpeg -i input.mov -map 0:a -c copy output.mov

• -map 0:a selects all audio streams only. Video and subtitles will be excluded.
• -c copy enables stream copy mode. This copies the audio and does not re-encode it. Remove -c copy if you want the audio to be re-encoded.
• Choose an output format that supports your audio format. See comparison of container formats.

Extract a specific audio track / stream

Example to extract audio stream #4:

ffmpeg -i input.mkv -map 0:a:3 -c copy output.m4a

• -map 0:a:3 selects audio stream #4 only (ffmpeg starts counting from 0).
• -c copy enables stream copy mode. This copies the audio and does not re-encode it. Remove -c copy if you want the audio to be re-encoded.
• Choose an output format that supports your audio format. See comparison of container formats.

Extract and re-encode audio / change format

Similar to the examples above, but without -c copy. Various examples:

ffmpeg -i input.mp4 -map 0:a output.mp3
ffmpeg -i input.mkv -map 0:a output.m4a
ffmpeg -i input.avi -map 0:a -c:a aac output.mka
ffmpeg -i input.mp4 output.wav

Extract all audio streams individually

This input in this example has 4 audio streams. Each audio stream will be output as single, individual files.

ffmpeg -i input.mov -map 0:a:0 output0.wav -map 0:a:1 output1.wav -map 0:a:2 output2.wav -map 0:a:3 output3.wav

Optionally add -c copy before each output file name to enable stream copy mode.

Extract a certain channel

Use the channelsplit filter. Example to get the Front Right (FR) channel from a stereo input:

ffmpeg -i stereo.wav -filter_complex "[0:a]channelsplit=channel_layout=stereo:channels=FR[right]" -map "[right]" front_right.wav

• channel_layout is the channel layout of the input. It is not automatically detected so you must provide the layout name.
• channels lists the channel(s) you want to extract.
• See ffmpeg -layouts for audio channel layout names (for channel_layout) and channel names (for channels).
• Using stream copy mode (-c copy) is not possible to use when filtering, so the audio must be re-encoded.
• See FFmpeg Wiki: Audio Channels for more examples.

What's the difference between -map and -vn?

ffmpeg has a default stream selection behavior that will select 1 stream per stream type (1 video, 1 audio, 1 subtitle, 1 data).

-vn is an old, legacy option. It excludes video from the default stream selection behavior. So audio, subtitles, and data are still automatically selected unless told not to with -an, -sn, or -dn.

-map is more complicated but more flexible and useful. -map disables the default stream selection behavior and ffmpeg will only include what you tell it to with -map option(s). -map can also be used to exclude certain streams or stream types. For example, -map 0 -map -0:v would include all streams except all video.

See FFmpeg Wiki: Map for more examples.

Errors

Invalid audio stream. Exactly one MP3 audio stream is required.

MP3 only supports 1 audio stream. The error means you are trying to put more than 1 audio stream into MP3. It can also mean you are trying to put non-MP3 audio into MP3.

WAVE files have exactly one stream

Similar to above.

Could not find tag for codec in stream #0, codec not currently supported in container

You are trying to put an audio format into an output that does not support it, such as PCM (WAV) into MP4.

Remove -c copy, choose a different output format (change the file name extension), or manually choose the encoder (such as -c:a aac).

See comparison of container formats.

Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument

This is a useless, generic error. The actual, informative error should immediately precede this generic error message.

Amit, I have used one way to achieve this with less coding and more efficient way.

but it uses Linq.

I posted it here because maybe the answer helps other SO.

Below DAL code converts datatable object to List of YourViewModel and it's easy to understand.

public static class DAL
{
        public static string connectionString = ConfigurationManager.ConnectionStrings["YourWebConfigConnection"].ConnectionString;

        // function that creates a list of an object from the given data table
        public static List<T> CreateListFromTable<T>(DataTable tbl) where T : new()
        {
            // define return list
            List<T> lst = new List<T>();

            // go through each row
            foreach (DataRow r in tbl.Rows)
            {
                // add to the list
                lst.Add(CreateItemFromRow<T>(r));
            }

            // return the list
            return lst;
        }

        // function that creates an object from the given data row
        public static T CreateItemFromRow<T>(DataRow row) where T : new()
        {
            // create a new object
            T item = new T();

            // set the item
            SetItemFromRow(item, row);

            // return 
            return item;
        }

        public static void SetItemFromRow<T>(T item, DataRow row) where T : new()
        {
            // go through each column
            foreach (DataColumn c in row.Table.Columns)
            {
                // find the property for the column
                PropertyInfo p = item.GetType().GetProperty(c.ColumnName);

                // if exists, set the value
                if (p != null && row[c] != DBNull.Value)
                {
                    p.SetValue(item, row[c], null);
                }
            }
        }

        //call stored procedure to get data.
        public static DataSet GetRecordWithExtendedTimeOut(string SPName, params SqlParameter[] SqlPrms)
        {
            DataSet ds = new DataSet();
            SqlCommand cmd = new SqlCommand();
            SqlDataAdapter da = new SqlDataAdapter();
            SqlConnection con = new SqlConnection(connectionString);

            try
            {
                cmd = new SqlCommand(SPName, con);
                cmd.Parameters.AddRange(SqlPrms);
                cmd.CommandTimeout = 240;
                cmd.CommandType = CommandType.StoredProcedure;
                da.SelectCommand = cmd;
                da.Fill(ds);
            }
            catch (Exception ex)
            {
               return ex;
            }

            return ds;
        }
}

Now, The way to pass and call method is below.

    DataSet ds = DAL.GetRecordWithExtendedTimeOut("ProcedureName");

    List<YourViewModel> model = new List<YourViewModel>();

    if (ds != null)
    {
        //Pass datatable from dataset to our DAL Method.
        model = DAL.CreateListFromTable<YourViewModel>(ds.Tables[0]);                
    }      

Till the date, for many of my applications, I found this as the best structure to get data.

Use Arrow function like this:

<button onClick={()=>{this.handleRemove(id)}}></button>

You could use vi

vi -c '%s/foo/bar/g' my.txt -c 'wq'

re.findall finds all the occurrence of the regex in a string and return in a list. Here, you are using a list of strings, you need this to use re.findall

Note - If the regex fails, an empty list is returned.

import re, sys

f = open('picklee', 'r')
lines = f.readlines()  
regex = re.compile(r'[A-Z]+')
for line in lines:
     print (re.findall(regex, line))

Simple code for replace all spaces

var str = 'How are you';
var replaced = str.split(' ').join('');

Out put: Howareyou

The easiest way to do this, with excellent performance and compatibility with both old and new browsers, is to include either Lo-Dash or Underscore in your page.

Then you can use either _.size(object) or _.keys(object).length

For your obj.Data, you could test this with:

console.log( _.size(obj.Data) );

or:

console.log( _.keys(obj.Data).length );

Lo-Dash and Underscore are both excellent libraries; you would find either one very useful in your code. (They are rather similar to each other; Lo-Dash is a newer version with some advantanges.)

Alternatively, you could include this function in your code, which simply loops through the object's properties and counts them:

function ObjectLength( object ) {
    var length = 0;
    for( var key in object ) {
        if( object.hasOwnProperty(key) ) {
            ++length;
        }
    }
    return length;
};

You can test this with:

console.log( ObjectLength(obj.Data) );

That code is not as fast as it could be in modern browsers, though. For a version that's much faster in modern browsers and still works in old ones, you can use:

function ObjectLength_Modern( object ) {
    return Object.keys(object).length;
}

function ObjectLength_Legacy( object ) {
    var length = 0;
    for( var key in object ) {
        if( object.hasOwnProperty(key) ) {
            ++length;
        }
    }
    return length;
}

var ObjectLength =
    Object.keys ? ObjectLength_Modern : ObjectLength_Legacy;

and as before, test it with:

console.log( ObjectLength(obj.Data) );

This code uses Object.keys(object).length in modern browsers and falls back to counting in a loop for old browsers.

But if you're going to all this work, I would recommend using Lo-Dash or Underscore instead and get all the benefits those libraries offer.

I set up a jsPerf that compares the speed of these various approaches. Please run it in any browsers you have handy to add to the tests.

Thanks to Barmar for suggesting Object.keys for newer browsers in his answer.

Just install package Synced?Sidebar?Bg:it will change the sidebar theme based on current color scheme.But it seems that every time you change the color scheme,sidebar will be changed after you open file Preferences.sublime-settings

You could try this SendKeys jQuery plugin:

http://bililite.com/blog/2011/01/23/improved-sendkeys/

$(element).sendkeys(string) inserts string at the insertion point in an input, textarea or other element with contenteditable=true. If the insertion point is not currently in the element, it remembers where the insertion point was when sendkeys was last called (if the insertion point was never in the element, it appends to the end).

Is there a way ( I mean how do I ) set a system property in a maven project? I want to access a property from my test [...]

You can set system properties in the Maven Surefire Plugin configuration (this makes sense since tests are forked by default). From Using System Properties:

<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.5</version>
        <configuration>
          <systemPropertyVariables>
            <propertyName>propertyValue</propertyName>
            <buildDirectory>${project.build.directory}</buildDirectory>
            [...]
          </systemPropertyVariables>
        </configuration>
      </plugin>
    </plugins>
  </build>
  [...]
</project>

and my webapp ( running locally )

Not sure what you mean here but I'll assume the webapp container is started by Maven. You can pass system properties on the command line using:

mvn -DargLine="-DpropertyName=propertyValue"

Update: Ok, got it now. For Jetty, you should also be able to set system properties in the Maven Jetty Plugin configuration. From Setting System Properties:

<project>
  ...
  <plugins>
    ...
      <plugin>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>maven-jetty-plugin</artifactId>
        <configuration>
         ...
         <systemProperties>
            <systemProperty>
              <name>propertyName</name>
              <value>propertyValue</value>
            </systemProperty>
            ...
         </systemProperties>
        </configuration>
      </plugin>
  </plugins>
</project>

Most easiest way in a single line of code

var base64Image = new Buffer( blob, 'binary' ).toString('base64');

If you are using Bootstrap 4, and you don't want to change your markup:

var $myGroup = $('#myGroup');
$myGroup.on('show.bs.collapse','.collapse', function() {
$myGroup.find('.collapse.show').collapse('hide');
});

There are two ways to write case statements, you seem to be using a combination of the two

case a.updatedDate
    when 1760 then 'Entered on' + a.updatedDate
    when 1710 then 'Viewed on' + a.updatedDate
    else 'Last Updated on' + a.updateDate
end

or

case 
    when a.updatedDate = 1760 then 'Entered on' + a.updatedDate
    when a.updatedDate = 1710 then 'Viewed on' + a.updatedDate
    else 'Last Updated on' + a.updateDate
end

are equivalent. They may not work because you may need to convert date types to varchars to append them to other varchars.

Try this:

window.open(url, '_blank');

This will open in new tab (if your code is synchronous and in this case it is. in other case it would open a window)

First of all, create a Github account and project in Github. Go to the root folder and follow steps.

The most important thing we forgot here is ignoring the file. Every time we run Gradle or build it creates new files that are changeable from build to build and pc to pc. We do not want all the files from Android Studio to be added to Git. Files like generated code, binary files (executables) should not be added to Git (version control). So please use .gitignore file while uploading projects to Github. It also reduces the size of the project uploaded to the server.

1. Go to root folder.
2. git init

3. Create .gitignore txt file in root folder. Place these content in the file. (this step not required if the file is auto-generated)

   *.iml .gradle /local.properties /.idea/workspace.xml /.idea/libraries .idea .DS_Store /build /captures .externalNativeBuild

4. git add .
5. git remote add origin https://github.com/username/project.git
6. git commit - m "My First Commit"
7. git push -u origin master

Note : As per suggestion from different developers, they always suggest to use git from the command line. It is up to you.

$(document).click((e) => {
  if ($.contains($(".the-one-you-can-click-and-should-still-open").get(0), e.target)) {
  } else {
    this.onClose();
  }
}); 

This line solved my problem:

<%#DateTime.Parse(Eval("DDDate").ToString()).ToString("dd-MM-yyyy")%>

Hosting asp.net 4.5/4.5.1 Web application on Local IIS 1)Be Sure IIS Installation before Visual Installation Installataion then aspnet_regiis will already registerd with IIS

If Not Install IIS and then Register aspnet_regiis with IIS by cmd Editor

For VS2012 and 32 bit OS Run Below code on command editor :

1)Install IIS First & then

2)

cd C:\Windows\Microsoft.NET\Framework\v4.0.30319   

  C:\Windows\Microsoft.NET\Framework\v4.0.30319> aspnet_regiis -i

For VS2012 and 64 bit OS Below code on command editor:

1)Install IIS First & then

2)

cd C:\Windows\Microsoft.NET\Framework64\v4.0.30319    
  C:\Windows\Microsoft.NET\Framework64\v4.0.30319> aspnet_regiis -i

BY Following Above Steps Current Version of VS2012 registered with IIS Hosting (VS2012 Web APP)

Create VS2012 Web Application(WebForm/MVC) then Build Application Right Click On WebApplication(WebForm/MVC) go to 'Properties' Click On 'Web' Tab on then 'Use Local IIS Web Server' Then Uncheck 'Use IIS Express' (If Visul Studio 2013 Select 'Local IIS' from Dropdown) Provide Project Url like "http://localhost/MvcDemoApp" Then Click On 'Create Virtual Directory' Button Then Open IIS by Prssing 'Window + R' Run Command and type 'inetmgr' and 'Enter' (or 'OK' Button) Then Expand 'Sites->Default Web Site' you Hosted Successfully. If Still Gets any Server Error like 'The resource cannot be found.' Then Include following code in web.config

 <configuration>
     <system.webServer>
         <modules runAllManagedModulesForAllRequests="true"></modules>

And Run Application

If still problem occurs Check application pool by : In iis Right click on application->Manage Application->Advanced setting->General. you see the application pool. then close advance setting window. click on 'Application Pools' you will see the all application pools in middle window. Right click on application pool in which application hosted(DefaultAppPool). click 'Basic Setting' -> Change .Net FrameWork Version to->.Net FrameWork v4.0.30349

By using the _MSC_VER macro.

JavaScript doesn't have associate arrays. You need to use Objects instead:

var obj = {};
var name = "name";
var val = 2;
obj[name] = val;
console.log(obj);?

To get value you can use now different ways:

console.log(obj.name);?
console.log(obj[name]);?
console.log(obj["name"]);?

Angular 2 version 2.3 was just released, and it includes native component inheritance. It looks like you can inherit and override whatever you want, except for templates and styles. Some references:

• New features in Angular 2.3

• Component Inheritance in Angular 2

• A Plunkr demonstrating component inheritance

I'd like to add a mention of the "brew" package. You can write a brew template file which would be LaTeX with placeholders, and then "brew" it up to create a .tex file to \include or \input into your LaTeX. Something like:

\begin{tabular}{l l}
A & <%= fit$A %> \\
B & <%= fit$B %> \\
\end{tabular}

The brew syntax can also handle loops, so you can create a table row for each row of a dataframe.

I was having the same problem until I read Jon Skeet's answer about the debugger displaying a single backslash with a double backslash even though the string may have a single backslash. I was not aware of that. So I changed my code from

text2 = text1.Replace(@"\\", @"/");

to

text2 = text1.Replace(@"\", @"/");

and that solved the problem. Note: I'm interfacing and R.Net which uses single forward slashes in path strings.

I've just spent quite some time troubleshooting this very problem. None of the proposed solutions worked. Turned out that our sysadmin by mistake assigned the same static IP to two unrelated servers belonging to different groups, but sitting on the same network. The end results were intermittently dropped vnc connections, browser that had to be refreshed several times to fetch the web page, and other strange things.

Easy with Docker version 1.10.1, build 9e83765.

First you need to create your own docker network (mynet123)

docker network create --subnet=172.18.0.0/16 mynet123

then, simply run the image (I'll take ubuntu as example)

docker run --net mynet123 --ip 172.18.0.22 -it ubuntu bash

then in ubuntu shell

ip addr

Additionally you could use

• --hostname to specify a hostname
• --add-host to add more entries to /etc/hosts

Here's some code that I ended up writing, based upon @Andrei's answer but without the elegancy/simplicity. The advantage is that it allows a more complex recursive merge and also differs between elements that should be connected with rbind and those that are just connected with c:

# Decided to move this outside the mapply, not sure this is 
# that important for speed but I imagine redefining the function
# might be somewhat time-consuming
mergeLists_internal <- function(o_element, n_element){
  if (is.list(n_element)){
    # Fill in non-existant element with NA elements
    if (length(n_element) != length(o_element)){
      n_unique <- names(n_element)[! names(n_element) %in% names(o_element)]
      if (length(n_unique) > 0){
        for (n in n_unique){
          if (is.matrix(n_element[[n]])){
            o_element[[n]] <- matrix(NA, 
                                     nrow=nrow(n_element[[n]]), 
                                     ncol=ncol(n_element[[n]]))
          }else{
            o_element[[n]] <- rep(NA, 
                                  times=length(n_element[[n]]))
          }
        }
      }

      o_unique <- names(o_element)[! names(o_element) %in% names(n_element)]
      if (length(o_unique) > 0){
        for (n in o_unique){
          if (is.matrix(n_element[[n]])){
            n_element[[n]] <- matrix(NA, 
                                     nrow=nrow(o_element[[n]]), 
                                     ncol=ncol(o_element[[n]]))
          }else{
            n_element[[n]] <- rep(NA, 
                                  times=length(o_element[[n]]))
          }
        }
      }
    }  

    # Now merge the two lists
    return(mergeLists(o_element, 
                      n_element))

  }
  if(length(n_element)>1){
    new_cols <- ifelse(is.matrix(n_element), ncol(n_element), length(n_element))
    old_cols <- ifelse(is.matrix(o_element), ncol(o_element), length(o_element))
    if (new_cols != old_cols)
      stop("Your length doesn't match on the elements,",
           " new element (", new_cols , ") !=",
           " old element (", old_cols , ")")
  }

  return(rbind(o_element, 
               n_element, 
               deparse.level=0))
  return(c(o_element, 
           n_element))
}
mergeLists <- function(old, new){
  if (is.null(old))
    return (new)

  m <- mapply(mergeLists_internal, old, new, SIMPLIFY=FALSE)
  return(m)
}

Here's my example:

v1 <- list("a"=c(1,2), b="test 1", sublist=list(one=20:21, two=21:22))
v2 <- list("a"=c(3,4), b="test 2", sublist=list(one=10:11, two=11:12, three=1:2))
mergeLists(v1, v2)

This results in:

$a
     [,1] [,2]
[1,]    1    2
[2,]    3    4

$b
[1] "test 1" "test 2"

$sublist
$sublist$one
     [,1] [,2]
[1,]   20   21
[2,]   10   11

$sublist$two
     [,1] [,2]
[1,]   21   22
[2,]   11   12

$sublist$three
     [,1] [,2]
[1,]   NA   NA
[2,]    1    2

Yeah, I know - perhaps not the most logical merge but I have a complex parallel loop that I had to generate a more customized .combine function for, and therefore I wrote this monster :-)

The normal way to control this is with git config

For example

git config --global core.autocrlf true

For details, scroll down in this link to Pro Git to the section named "core.autocrlf"

If you want to know what file this is saved in, you can run the command:

git config --global --edit

and the git global config file should open in a text editor, and you can see where that file was loaded from.

Late to the party, but another easy way of comparing NSDate objects is to convert them into primitive types which allows for easy use of '>' '<' '==' etc

eg.

if ([dateA timeIntervalSinceReferenceDate] > [dateB timeIntervalSinceReferenceDate]) {
    //do stuff
}

timeIntervalSinceReferenceDate converts the date into seconds since the reference date (1 January 2001, GMT). As timeIntervalSinceReferenceDate returns a NSTimeInterval (which is a double typedef), we can use primitive comparators.

MVC lets you have more than one form on a page, A small feature I know but it is handy!

Also the MVC pattern I feel make the code easier to maintain, esp. when you revisiting it after a few months.

Adding to @zzzzzzz answer, I ran the command:python3 -c "import sys; print(sys.path)" and it provided me with different paths comparing to the same command with python. The paths that were displayed with python3 were "python3 oriented".

See the output of the two different commands:

python -c "import sys; print(sys.path)"

['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/local/lib/python2.7/dist-packages/setuptools-39.1.0-py2.7.egg', '/usr/lib/python2.7/dist-packages']

python3 -c "import sys; print(sys.path)"

['', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']

Both commands were executed on my Ubuntu 18.04 machine.

import pandas as pd

from sklearn.model_selection import train_test_split

datafile_name = 'path_to_data_file'

data = pd.read_csv(datafile_name)

target_attribute = data['column_name']

X_train, X_test, y_train, y_test = train_test_split(data, target_attribute, test_size=0.8)

Little something I created for this:

function getFiles($path) {
    if (is_dir($path)) {
        $files = scandir($path);
        $res = [];
        foreach ($files as $key => $file) {
            if ($file != "." && $file != "..") {
                array_push($res, $file);
            }
        }
        return $res;
    }
    return false;
}

Just a note in addition to the other answers.

If an initial value is supplied to reduce then sometimes its type must be specified, viz:-

a.reduce(fn, [])

may have to be

a.reduce<string[]>(fn, [])

or

a.reduce(fn, <string[]>[])

Inline elements:

1. respect left & right margins and padding, but not top & bottom
2. cannot have a width and height set
3. allow other elements to sit to their left and right.
4. see very important side notes on this here.

Block elements:

1. respect all of those
2. force a line break after the block element
3. acquires full-width if width not defined

Inline-block elements:

1. allow other elements to sit to their left and right
2. respect top & bottom margins and padding
3. respect height and width

From W3Schools:

• An inline element has no line break before or after it, and it tolerates HTML elements next to it.

• A block element has some whitespace above and below it and does not tolerate any HTML elements next to it.

• An inline-block element is placed as an inline element (on the same line as adjacent content), but it behaves as a block element.

When you visualize this, it looks like this:

The image is taken from this page, which also talks some more about this subject.

Working on Mac I followed the answer of Sean Patrick Floyd placing a settings.xml like above in my user folder /Users/user/.m2/

But this did not help. So I opened a Terminal and did a ls -la on the folder. This was showing

-rw-r--r--@

thus staff and everone can at least read the file. So I wondered if the message isn't wrong and if the real cause is the lack of write permissions. I set the file to:

-rw-r--rw-@

This did it. The message disappeared.

It makes more sense to join the item with the orders than with the people !

SELECT
    people.pe_name,
    COUNT(distinct orders.ord_id) AS num_orders,
    COUNT(items.item_id) AS num_items
FROM
    people
    INNER JOIN orders ON orders.pe_id = people.pe_id
         INNER JOIN items ON items.ord_id = orders.ord_id
GROUP BY
    people.pe_id;

Joining the items with the people provokes a lot of doublons. For example, the cake items in order 3 will be linked with the order 2 via the join between the people, and you don't want this to happen !!

So :

1- You need a good understanding of your schema. Items are link to orders, and not to people.

2- You need to count distinct orders for one person, else you will count as many items as orders.

Well, the first interpretation is correct. However, your reasoning about the "signed semantics" in this context is wrong.

Again, your first interpretation is correct. Unsigned arithmetic follow the rules of modulo arithmetic, meaning that 0x0000 - 0x0001 evaluates to 0xFFFF for 32-bit unsigned types.

However, the second interpretation (the one based on "signed semantics") is also required to produce the same result. I.e. even if you evaluate 0 - 1 in the domain of signed type and obtain -1 as the intermediate result, this -1 is still required to produce 0xFFFF when later it gets converted to unsigned type. Even if some platform uses an exotic representation for signed integers (1's complement, signed magnitude), this platform is still required to apply rules of modulo arithmetic when converting signed integer values to unsigned ones.

For example, this evaluation

signed int a = 0, b = 1;
unsigned int c = a - b;

is still guaranteed to produce UINT_MAX in c, even if the platform is using an exotic representation for signed integers.

I think what you are looking for is to keep the background image fixed and just move the content on scroll. For that you have to simply use the following css property :

background-attachment: fixed;

This still loops through the cartesian product of the two lists, but it does it one line:

>>> lines1 = ['soup', 'butter', 'venison']
>>> lines2 = ['prune', 'rye', 'turkey']
>>> search_strings = ['a', 'b', 'c']
>>> any(s in l for l in lines1 for s in search_strings)
True
>>> any(s in l for l in lines2 for s in search_strings)
False

This also have the advantage that any short-circuits, and so the looping stops as soon as a match is found. Also, this only finds the first occurrence of a string from search_strings in linesX. If you want to find multiple occurrences you could do something like this:

>>> lines3 = ['corn', 'butter', 'apples']
>>> [(s, l) for l in lines3 for s in search_strings if s in l]
[('c', 'corn'), ('b', 'butter'), ('a', 'apples')]

If you feel like coding something more complex, it seems the Aho-Corasick algorithm can test for the presence of multiple substrings in a given input string. (Thanks to Niklas B. for pointing that out.) I still think it would result in quadratic performance for your use-case since you'll still have to call it multiple times to search multiple lines. However, it would beat the above (cubic, on average) algorithm.

Simple steps (using git + hub => GitHub):

1. Install Hub (GitHub).

   • OS X: brew install hub
   • having Go: go get github.com/github/hub

   • otherwise (having Go as well):

     git clone https://github.com/github/hub.git && cd hub && ./script/build
     

2. Go to your repo or create empty one: mkdir foo && cd foo && git init.

3. Run: hub create, it'll ask you about GitHub credentials for the first time.

   Usage: hub create [-p] [-d DESCRIPTION] [-h HOMEPAGE] [NAME]

   Example: hub create -d Description -h example.com org_name/foo_repo

   Hub will prompt for GitHub username & password the first time it needs to access the API and exchange it for an OAuth token, which it saves in ~/.config/hub.

   To explicitly name the new repository, pass in NAME, optionally in ORGANIZATION/NAME form to create under an organization you're a member of.

   With -p, create a private repository, and with -d and -h set the repository's description and homepage URL, respectively.

   To avoid being prompted, use GITHUB_USER and GITHUB_PASSWORD environment variables.

4. Then commit and push as usual or check hub commit/hub push.

For more help, run: hub help.

enumerate is trivial, and so is re-implementing it to accept a start:

def enumerate(iterable, start = 0):
    n = start
    for i in iterable:
        yield n, i
        n += 1

Note that this doesn't break code using enumerate without start argument. Alternatively, this oneliner may be more elegant and possibly faster, but breaks other uses of enumerate:

enumerate = ((index+1, item) for index, item)

The latter was pure nonsense. @Duncan got the wrapper right.

As MRA said, you shouldn't try to dodge a 429 Too Many Requests but instead handle it accordingly. You have several options depending on your use-case:

1) Sleep your process. The server usually includes a Retry-after header in the response with the number of seconds you are supposed to wait before retrying. Keep in mind that sleeping a process might cause problems, e.g. in a task queue, where you should instead retry the task at a later time to free up the worker for other things.

2) Exponential backoff. If the server does not tell you how long to wait, you can retry your request using increasing pauses in between. The popular task queue Celery has this feature built right-in.

3) Token bucket. This technique is useful if you know in advance how many requests you are able to make in a given time. Each time you access the API you first fetch a token from the bucket. The bucket is refilled at a constant rate. If the bucket is empty, you know you'll have to wait before hitting the API again. Token buckets are usually implemented on the other end (the API) but you can also use them as a proxy to avoid ever getting a 429 Too Many Requests. Celery's rate_limit feature uses a token bucket algorithm.

Here is an example of a Python/Celery app using exponential backoff and rate-limiting/token bucket:

class TooManyRequests(Exception):
"""Too many requests"""

@task(
   rate_limit='10/s',
   autoretry_for=(ConnectTimeout, TooManyRequests,),
   retry_backoff=True)
def api(*args, **kwargs):
  r = requests.get('placeholder-external-api')

  if r.status_code == 429:
    raise TooManyRequests()

For Excel 2010 it should be UTF-8. Instruction by MS :
http://msdn.microsoft.com/en-us/library/bb507946:

"The basic document structure of a SpreadsheetML document consists of the Sheets and Sheet elements, which reference the worksheets in the Workbook. A separate XML file is created for each Worksheet. For example, the SpreadsheetML for a workbook that has two worksheets name MySheet1 and MySheet2 is located in the Workbook.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> 
<workbook xmlns=http://schemas.openxmlformats.org/spreadsheetml/2006/main xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">
    <sheets>
        <sheet name="MySheet1" sheetId="1" r:id="rId1" /> 
        <sheet name="MySheet2" sheetId="2" r:id="rId2" /> 
    </sheets>
</workbook>

The worksheet XML files contain one or more block level elements such as SheetData. sheetData represents the cell table and contains one or more Row elements. A row contains one or more Cell elements. Each cell contains a CellValue element that represents the value of the cell. For example, the SpreadsheetML for the first worksheet in a workbook, that only has the value 100 in cell A1, is located in the Sheet1.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" ?> 
<worksheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
    <sheetData>
        <row r="1">
            <c r="A1">
                <v>100</v> 
            </c>
        </row>
    </sheetData>
</worksheet>

In addition to the other answers here showing you how to git checkout <the-hash-you-want> it's worth knowing you can switch back to where you were using:

git checkout @{-1}

This is often more convenient than:

git checkout what-was-that-original-branch-called-again-question-mark

As you might anticipate, git checkout @{-2} will take you back to the branch you were at two git checkouts ago, and similarly for other numbers. If you can remember where you were for bigger numbers, you should get some kind of medal for that.

Sadly for productivity, git checkout @{1} does not take you to the branch you will be on in future, which is a shame.

This error is because your server doesn't have a valid SSL certificate. Hence we need to tell the client to use a different TrustManager. Here is a sample code:

SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {

    public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException {
    }

    public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException {
    }

    public X509Certificate[] getAcceptedIssuers() {
        return null;
    }
};
ctx.init(null, new TrustManager[]{tm}, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ClientConnectionManager ccm = base.getConnectionManager();
SchemeRegistry sr = ccm.getSchemeRegistry();
sr.register(new Scheme("https", 443, ssf));

client = new DefaultHttpClient(ccm, base.getParams());

You don't need to configure anything. Just make sure that the requests map to your PHP file and use requests with path info. For example, if you have in the root a file named handler.php with this content:

<?php

var_dump($_SERVER['REQUEST_METHOD']);
var_dump($_SERVER['REQUEST_URI']);
var_dump($_SERVER['PATH_INFO']);

if (($stream = fopen('php://input', "r")) !== FALSE)
    var_dump(stream_get_contents($stream));

The following HTTP request would work:

Established connection with 127.0.0.1 on port 81
PUT /handler.php/bla/foo HTTP/1.1
Host: localhost:81
Content-length: 5
 
boo

You can hide the "php" extension with MultiViews or you can make URLs completely logical with mod_rewrite.

See also the documentation for the AcceptPathInfo directive and this question on how to make PHP not parse POST data when enctype is multipart/form-data.

It is quite easy. Here is the API Interface

public interface Api {

    @Multipart
    @POST("upload")
    Call<MyResponse> uploadImage(@Part("image\"; filename=\"myfile.jpg\" ") RequestBody file, @Part("desc") RequestBody desc);

}

And you can use the following code to make a call.

private void uploadFile(File file, String desc) {

        //creating request body for file
        RequestBody requestFile = RequestBody.create(MediaType.parse(getContentResolver().getType(fileUri)), file);
        RequestBody descBody = RequestBody.create(MediaType.parse("text/plain"), desc);

        //The gson builder
        Gson gson = new GsonBuilder()
                .setLenient()
                .create();


        //creating retrofit object
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(Api.BASE_URL)
                .addConverterFactory(GsonConverterFactory.create(gson))
                .build();

        //creating our api 
        Api api = retrofit.create(Api.class);

        //creating a call and calling the upload image method 
        Call<MyResponse> call = api.uploadImage(requestFile, descBody);

        //finally performing the call 
        call.enqueue(new Callback<MyResponse>() {
            @Override
            public void onResponse(Call<MyResponse> call, Response<MyResponse> response) {
                if (!response.body().error) {
                    Toast.makeText(getApplicationContext(), "File Uploaded Successfully...", Toast.LENGTH_LONG).show();
                } else {
                    Toast.makeText(getApplicationContext(), "Some error occurred...", Toast.LENGTH_LONG).show();
                }
            }

            @Override
            public void onFailure(Call<MyResponse> call, Throwable t) {
                Toast.makeText(getApplicationContext(), t.getMessage(), Toast.LENGTH_LONG).show();

As an alternative to sed or perl you may consider to use ed(1) and POSIX character classes.

Note: ed(1) reads the entire file into memory to edit it in-place, so for really large files you should use sed -i ..., perl -i ...

# see:
# - http://wiki.bash-hackers.org/doku.php?id=howto:edit-ed
# - http://en.wikipedia.org/wiki/Regular_expression#POSIX_character_classes

# test
echo $'aaa \177 bbb \200 \214 ccc \254 ddd\r\n' > testfile
ed -s testfile <<< $',l' 
ed -s testfile <<< $'H\ng/[^[:graph:][:space:][:cntrl:]]/s///g\nwq'
ed -s testfile <<< $',l'

To get the last character of a string, you can use the split('').pop() function.

const myText = "The last character is J";
const lastCharater = myText.split('').pop();
console.log(lastCharater); // J

It's works because when the split('') function has empty('') as parameter, then each character of the string is changed to an element of an array. Thereby we can use the pop() function which returns the last element of that array, which is, the 'J' character.

I prefer Consolas.

You can define some default values and it prevents the fields from being serialized.

    [XmlElement, DefaultValue("")]
    string data;

    [XmlArray, DefaultValue(null)]
    List<string> data;

double quotes worked in oracle when I had the keyword as one of the column name.

eg:

select t."size" from table t 

A couple of things might affect the results you're seeing:

1. You're treating clock_t as a floating-point type, I don't think it is.
2. You might be expecting (1^4) to do something else than compute the bitwise XOR of 1 and 4., i.e. it's 5.
3. Since the XOR is of constants, it's probably folded by the compiler, meaning it doesn't add a lot of work at runtime.
4. Since the output is buffered (it's just formatting the string and writing it to memory), it completes very quickly indeed.

You're not specifying how fast your machine is, but it's not unreasonable for this to run very quickly on modern hardware, no.

If you have it, try adding a call to sleep() between the start/stop snapshots. Note that sleep() is POSIX though, not standard C.

Here is a sample query for a table having a foreign key relationship to the same table with a query parameter.

SET @x = -1;
SELECT id, categoryName 
FROM Catergory WHERE IF(@x > 0,category_ParentId = @x,category_ParentId IS NOT NULL);

@x can be changed.

Less than or equal:

User.objects.filter(userprofile__level__lte=0)

Greater than or equal:

User.objects.filter(userprofile__level__gte=0)

Likewise, lt for less than and gt for greater than. You can find them all in the documentation.

NOTE: This answer obviously defeats the purpose of SSL and should be used sparingly as a last resort.

For those having issues with scripts that download scripts that download scripts and want a quick fix, create a file called ~/.curlrc

With the contents

--insecure

This will cause curl to ignore SSL certificate problems by default.

Make sure you delete the file when done.

UPDATE

12 days later I got notified of an upvote on this answer, which made me go "Hmmm, did I follow my own advice remember to delete that .curlrc?", and discovered I hadn't. So that really underscores how easy it is to leave your curl insecure by following this method.

It depends on what you mean by "convert an int to char".

If you simply want to cast the value in the int, you can cast it using Java's typecast notation:

int i = 97; // 97 is 'a' in ASCII
char c = (char) i; // c is now 'a'

If you mean transforming the integer 1 into the character '1', you can do it like this:

if (i >= 0 && i <= 9) {
char c = Character.forDigit(i, 10);
....
}

MATLAB is a popular and widely adapted piece of a sophisticated software package. It'd be a mistake to think it's merely a math software since it has a wide range of "toolboxes". I recently used Matplotlib to plot some data from a database and it did the job without needing all the bells and whistles of MATLAB. However, it may not be proper to compare Python and MATLAB in every situation. As with everything else the decision depends on what you need to do.

I used MATLAB in undergrad for control systems design and simulation and also for image processing in grad school. For these fields MATLAB makes the most sense because of the powerful control and image processing toolboxes. As everyone mentioned, array operations, which are used in every MATLAB script you'd need to write, are very easy with MATLAB.

Another nice thing about MATLAB is that it's very easy and fast to do prototyping and trying out ideas using the built in toolbox functions. For instance, it takes no effort to import an image and compute it's histogram or do some simple processing on it. One disadvantage of MATLAB could be it's speed because of its interpreted nature. However, if one really needs speed than he can choose to implement the tested logic in C/C++, etc.

For further comparison with Python, I can say that MATLAB provides a full package for you to do your work without the need of looking around for external libraries and implementing extra functions.

One last point about MATLAB which I see is not mentioned in the answers here is that it has a very powerful visual modeling/simulation environment called Simulink. It's easier to design and simulate larger systems with Simulink.

Finally, again, it all depends on the problem you need to solve. If your problem domain can make use of one of MATLAB's toolboxes and you have access to MATLAB then you can be sure that you'll have the right tool to solve it.

You can also use the shorter format

From the man page:

%F     full date; same as %Y-%m-%d

Example:

#!/bin/bash
date_today=$(date +%F)
date_dir=$(date +%F -d yesterday)

Just add overflow:hidden to the table with border-radius.

.tablewithradius {
  overflow:hidden ;
  border-radius: 15px;
}

If your using ng-repeat $index works like this

  name="QTY{{$index}}"

and

   <td>
       <input ng-model="r.QTY" class="span1" name="QTY{{$index}}" ng-            
        pattern="/^[\d]*\.?[\d]*$/" required/>
        <span class="alert-error" ng-show="form['QTY' + $index].$error.pattern">
        <strong>Requires a number.</strong></span>
        <span class="alert-error" ng-show="form['QTY' + $index].$error.required">
       <strong>*Required</strong></span>
    </td>

we have to show the ng-show in ng-pattern

   <span class="alert-error" ng-show="form['QTY' + $index].$error.pattern">
   <span class="alert-error" ng-show="form['QTY' + $index].$error.required">

A FragmentActivity is a subclass of Activity that was built for the Android Support Package.

The FragmentActivity class adds a couple new methods to ensure compatibility with older versions of Android, but other than that, there really isn't much of a difference between the two. Just make sure you change all calls to getLoaderManager() and getFragmentManager() to getSupportLoaderManager() and getSupportFragmentManager() respectively.

The error SQLSTATE[HY000] [1040] Too many connections is an SQL error, and has to do with the sql server. There could be other applications connecting to the server. The server has a maximum available connections number.

If you have phpmyadmin, you can use the 'variables' tab to check what the setting is.

You can also query the status table like so:

show status like '%onn%';

Or some variance on that. check the manual for what variables there are

(be aware, 'connections' is not the current connections, check that link :) )

DateTime.ParseExact(input,"yyyyMMdd HH:mm",null);

assuming you meant to say that minutes followed the hours, not seconds - your example is a little confusing.

The ParseExact documentation details other overloads, in case you want to have the parse automatically convert to Universal Time or something like that.

As @Joel Coehoorn mentions, there's also the option of using TryParseExact, which will return a Boolean value indicating success or failure of the operation - I'm still on .Net 1.1, so I often forget this one.

If you need to parse other formats, you can check out the Standard DateTime Format Strings.

Actually, the entire approach would be cleaner if you only had to use one instance of StringBuffer, instead of creating one in every recursive call... I would go for:

private String getWhoozitYs(){
     StringBuffer sb = new StringBuffer();
     while (generator.nextBoolean()) {
         sb.append("y");
     }

     return sb.toString();
}

SQL Developer seems to only output the DBMS_OUTPUT text when you have explicitly turned on the DBMS_OUTPUT window pane.

Go to (Menu) VIEW -> Dbms_output to invoke the pane.

Click on the Green Plus sign to enable output for your connection and then run the code.

EDIT: Don't forget to set the buffer size according to the amount of output you are expecting.

Try adding an event listener for clicks:

document.getElementById('button').addEventListener("click", function() {
   alert("You clicked me");
}?);?

Using addEventListener is probably a better idea then setting onclick - onclick can easily be overwritten by another piece of code.

You can use a variable to store whether or not the button has been clicked before:

var clicked = false
document.getElementById('button').addEventListener("click", function() {
   clicked = true
}?);?

I had a problem with a CSV that contains fields with a quote character in them, so using the TextFieldParser, I came up with the following:

private static string[] parseCSVLine(string csvLine)
{
  using (TextFieldParser TFP = new TextFieldParser(new MemoryStream(Encoding.UTF8.GetBytes(csvLine))))
  {
    TFP.HasFieldsEnclosedInQuotes = true;
    TFP.SetDelimiters(",");

    try 
    {           
      return TFP.ReadFields();
    }
    catch (MalformedLineException)
    {
      StringBuilder m_sbLine = new StringBuilder();

      for (int i = 0; i < TFP.ErrorLine.Length; i++)
      {
        if (i > 0 && TFP.ErrorLine[i]== '"' &&(TFP.ErrorLine[i + 1] != ',' && TFP.ErrorLine[i - 1] != ','))
          m_sbLine.Append("\"\"");
        else
          m_sbLine.Append(TFP.ErrorLine[i]);
      }

      return parseCSVLine(m_sbLine.ToString());
    }
  }
}

A StreamReader is still used to read the CSV line by line, as follows:

using(StreamReader SR = new StreamReader(FileName))
{
  while (SR.Peek() >-1)
    myStringArray = parseCSVLine(SR.ReadLine());
}

  $this->db->like('title', 'match', 'before'); 
 // Produces: WHERE title LIKE '%match' 

 $this->db->like('title', 'match', 'after'); 
// Produces: WHERE title LIKE 'match%' 

$this->db->like('title', 'match', 'both'); 
// Produces: WHERE title LIKE '%match%'

sleep is a good way to avoid overload on the cpu

not sure if it's really clever, but I usually use

while(not sleep(5)):
    #code to execute

sleep method always returns None.

Dim shll : Set shll = CreateObject("WScript.Shell")
Set Rt = shll.Exec("Notepad") : wscript.sleep 4000 : Rt.Terminate

Run the process with .Exec.

Then wait for 4 seconds.

After that kill this process.

It seems that so far you've just followed the first step of the instructions, headed "Create an offline installation folder". Have you done the second step? "Install from the offline installation folder" - that is, install the certificates and then run vs_Community.exe from inside the folder.

there is an important difference between delete and splice:

ORIGINAL ARRAY:

[<1 empty item>, 'one',<3 empty items>, 'five', <3 empty items>,'nine']

AFTER SPLICE (array.splice(1,1)):

[ <4 empty items>, 'five', <3 empty items>, 'nine' ]

AFTER DELETE (delete array[1]):

[ <5 empty items>, 'five', <3 empty items>, 'nine' ]

A fast way of doing this is to reconstruct using numpy to slice the underlying arrays. See timings below.

mask = s.values != 1
pd.Series(s.values[mask], s.index[mask])

These two attributes are commonly confused:

• android:gravity sets the gravity of the content of the View it's used on.
• android:layout_gravity sets the gravity of the View or Layout relative to its parent.

So either put android:gravity="center" on the parent or android:layout_gravity="center" on the LinearLayout itself.

I have caught myself a number of times mixing them up and wondering why things weren't centering properly...

I faced the same problem and struggled for an hour to get pass through by reading the documents and the other issues reported in Stack Overflow but I didn't find any answer to it. So, here is the guide to successfully run the phonegap/cordova in Windows Machine.

Follow these steps

1. Download and Install node.js from http://nodejs.org/
2. Run the command npm install -g phonegap (in case of phonegap installation) or run the command npm install -g cordova (in case of Cordova installation).

3. As the installation gets completed you can notice this:

4. Notice the above line you can see the path were the file is mentioned. Copy that path. In my case it is C:\Users\binaryuser\AppData\Roaming\npm\cordova so use cd C:\Users\binaryuser\AppData\Roaming\npm\ and type cordova. There it is, it finally works.

5. Since the -g key value isn't working you have set the Environment Variables path:
   1. Press Win + Pause|Break or right click on Computer and choose Properties.
   2. Click Advanced system settings on the left.
   3. Click Environment Variables under the Advanced tab.
   4. Select the PATH variable and click Edit.
   5. Copy the path mentioned above to the value field and press OK.

Microsoft Visual Studio is funny when your using the installer you MUST checkbox a-lot of options to bypass the .netframework(somewhat) to make more c++ instead of c sharp applications, such as the clr options under dekstop development... in visual studio installer.... difference is c++ win32 console project or a c++ CLR console project. So whats the difference? Well i'm not going to list all of the files CLR includes but since most good c++ kernals are in linux... so CLR allows you to bypass a-lot of the windows .netframework b/c visual studio was really meant for you to make apps in C sharp.

Heres a C++ win32 console project!

#include "stdafx.h"
#include <iostream>
using namespace std;
int main( )
{
cout<<"Hello World"<<endl;
return 0;
}

Now heres a c++ CLR console project!

#include "stdafx.h"

using namespace System;

int main(array<System::String ^> ^args)
{
Console::WriteLine("Hello World");
return 0;
}

Both programs do the same thing .... CLR just looks more frameworked class overloading methodology so microsoft can great it's own vast library you should familiarize yourself w/ if so inclined. https://msdn.microsoft.com/en-us/library/2e6a4at9.aspx

example below is getting the host and redirecting to another page.

var host = $(location).attr('host');
window.location.replace("http://"+host+"/TEST_PROJECT/INDEXINGPAGE");

uname -a works with my fc11

regards,

What about ordering desc by the desired property,

   blah = blah.OrderByDescending(x => x.Property);

And then doing something like

  if (!descending)
  {
       blah = blah.Reverse()
  }
  else
  {
      // Already sorted desc ;)
  }

Is it Reverse() too slow?

Here is the solution

I followed to the help page of memory.limit and found out that on my computer R by default can use up to ~ 1.5 GB of RAM and that the user can increase this limit. Using the following code,

>memory.limit()
[1] 1535.875
> memory.limit(size=1800)

helped me to solve my problem.

In addition to the other (somewhat lengthy) answers: even ignoring old systems that support only 7-bit ASCII, basic problems with supplying binary data in text-mode are:

• Newlines are typically transformed in text-mode.
• One must be careful not to treat a NUL byte as the end of a text string, which is all too easy to do in any program with C lineage.

Similar to @monowerker, I needed to reindex an array using an object's key...

$new = array();
$old = array(
  (object)array('id' => 123),
  (object)array('id' => 456),
  (object)array('id' => 789),
);
print_r($old);

array_walk($old, function($item, $key, &$reindexed_array) {
  $reindexed_array[$item->id] = $item;
}, &$new);

print_r($new);

This resulted in:

Array
(
    [0] => stdClass Object
        (
            [id] => 123
        )
    [1] => stdClass Object
        (
            [id] => 456
        )
    [2] => stdClass Object
        (
            [id] => 789
        )
)
Array
(
    [123] => stdClass Object
        (
            [id] => 123
        )
    [456] => stdClass Object
        (
            [id] => 456
        )
    [789] => stdClass Object
        (
            [id] => 789
        )
)

For symfony 2.6 and above we can use

{{ app.user.getFirstname() }}

as app.security global variable for Twig template has been deprecated and will be removed from 3.0

more info:

http://symfony.com/blog/new-in-symfony-2-6-security-component-improvements

and see the global variables in

http://symfony.com/doc/current/reference/twig_reference.html

try this to get the current date.You can also get current hour, minutes and seconds by using getters :

new Date(System.currentTimeMillis()).get....()

To convert any date, for example utc:

moment( moment().utc().format( "YYYY-MM-DD HH:mm:ss" )).toDate()

Take a look at the docs regarding Python on Mac.

The version at /System/Library/Frameworks/Python.framework is installed by Apple and is used by the system. It is version 3.3 in your case. You can access and use this Python interpreter, but you shouldn't try to remove it, and it may not be the one that comes up when you type "Python" in a terminal or click on an icon to launch it.

You must have installed another version of Python (2.7) on your own at some point, and now that is the one that is launched by default.

As other answers have pointed out, you can use the command which python on your terminal to find the path to this other installation.

One of my concerns with phpMyAdmin was that by default, all MySQL users can access the db. If DB's root password is compromised, someone can wreck havoc on the db. I wanted to find a way to avoid that by restricting which MySQL user can login to phpMyAdmin.

I have found using AllowDeny configuration in PhpMyAdmin to be very useful. http://wiki.phpmyadmin.net/pma/Config#AllowDeny_.28rules.29

AllowDeny lets you configure access to phpMyAdmin in a similar way to Apache. If you set the 'order' to explicit, it will only grant access to users defined in 'rules' section. In the rules, section you restrict MySql users who can access use the phpMyAdmin.

$cfg['Servers'][$i]['AllowDeny']['order'] = 'explicit'
$cfg['Servers'][$i]['AllowDeny']['rules'] = array('pma-user from all')

Now you have limited access to the user named pma-user in MySQL, you can grant limited privilege to that user.

grant select on db_name.some_table to 'pma-user'@'app-server'

Here's how you can do that.

Writing the persistent cookie.

//create a cookie
HttpCookie myCookie = new HttpCookie("myCookie");

//Add key-values in the cookie
myCookie.Values.Add("userid", objUser.id.ToString());

//set cookie expiry date-time. Made it to last for next 12 hours.
myCookie.Expires = DateTime.Now.AddHours(12);

//Most important, write the cookie to client.
Response.Cookies.Add(myCookie);

Reading the persistent cookie.

//Assuming user comes back after several hours. several < 12.
//Read the cookie from Request.
HttpCookie myCookie = Request.Cookies["myCookie"];
if (myCookie == null)
{
    //No cookie found or cookie expired.
    //Handle the situation here, Redirect the user or simply return;
}

//ok - cookie is found.
//Gracefully check if the cookie has the key-value as expected.
if (!string.IsNullOrEmpty(myCookie.Values["userid"]))
{
    string userId = myCookie.Values["userid"].ToString();
    //Yes userId is found. Mission accomplished.
}

1.2975118E7 is scientific notation.

1.2975118E7 = 1.2975118 * 10^7 = 12975118

Also, Math.round(f) returns an integer. You can't use it to get your desired format x.xx.

You could use String.format.

String s = String.format("%.2f", 1.2975118);
// 1.30

If you want to apply it as a commit, use git am.

You can combine multiple selectors and this is so cool knowing that you can select every attribute and attribute based on their value like href based on their values with CSS only..

Attributes selectors allows you play around some extra with id and class attributes

I've created a library called HTML5DOMDocument that is freely available at https://github.com/ivopetkov/html5-dom-document-php

It supports query selectors too that I think will be extremely helpful in your case. Here is some example code:

$dom = new IvoPetkov\HTML5DOMDocument();
$dom->loadHTML('<!DOCTYPE html><html><body><h1>Hello</h1><div class="content">This is some text</div></body></html>');
echo $dom->querySelector('h1')->innerHTML;

Your problem is that the loop continues to run even thought you've "made up your mind" already. You should add the line break after a=a+1

TextBox2.Text = "Line 1" & Environment.NewLine & "Line 2"

or

TextBox2.Text = "Line 1"
TextBox2.Text += Environment.NewLine
TextBox2.Text += "Line 2"

This, is how it is done.

I successfully used "soap" package (https://www.npmjs.com/package/soap) on more than 10 tracking WebApis (Tradetracker, Bbelboon, Affilinet, Webgains, ...).

Problems usually come from the fact that programmers does not investigate to much about what remote API needs in order to connect or authenticate.

For instance PHP resends cookies from HTTP headers automatically, but when using 'node' package, it have to be explicitly set (for instance by 'soap-cookie' package)...

How i solved this

This error occurs because you have set your build variants to release mode. set it to build mode and run project again.

If you want to run in release mode, just generate a signed apk the way we do it normally when releasing the app

Observer pattern is used when there is one-to-many relationship between objects such as if one object is modified, its dependent objects are to be notified automatically.

The text 'dasda' will never not be within a tag, right? Semantically and to be valid HTML it as to be, just add the clear class to that:

http://jsfiddle.net/EyNnk/2/

I've been looking around for this, but then I realize, damn my website uses php!!! Why not use the trim function on the text input and play with the max length....

Here is a possible solution too for those using php: http://ideone.com/PsTaI

<?php
$s = "In the beginning there was a tree.";
$max_length = 10;

if (strlen($s) > $max_length)
{
   $offset = ($max_length - 3) - strlen($s);
   $s = substr($s, 0, strrpos($s, ' ', $offset)) . '...';
}

echo $s;
?>

Try something like:

$("#photo").load(function() {
    alert("Hello from Image");
});

I just wrote this helper function. Put it in App_Code/JS.cshtml:

@using System.Web.Script.Serialization
@helper Encode(object obj)
{
    @(new HtmlString(new JavaScriptSerializer().Serialize(obj)));
}

Then in your example, you can do something like this:

var title = @JS.Encode(Model.Title);

Notice how I don't put quotes around it. If the title already contains quotes, it won't explode. Seems to handle dictionaries and anonymous objects nicely too!

You can access documents directory using this code it is basically used for storing file in plist format:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths firstObject];
return documentsDirectory;

It seems to me like people dislike a goto statement a lot, so I felt the need to straighten this out a bit.

I believe the 'emotions' people have about goto eventually boil down to understanding of code and (misconceptions) about possible performance implications. Before answering the question, I will therefore first go into some of the details on how it's compiled.

As we all know, C# is compiled to IL, which is then compiled to assembler using an SSA compiler. I'll give a bit of insights into how this all works, and then try to answer the question itself.

From C# to IL

First we need a piece of C# code. Let's start simple:

foreach (var item in array)
{
    // ... 
    break;
    // ...
}

I'll do this step by step to give you a good idea of what happens under the hood.

First translation: from foreach to the equivalent for loop (Note: I'm using an array here, because I don't want to get into details of IDisposable -- in which case I'd also have to use an IEnumerable):

for (int i=0; i<array.Length; ++i)
{
    var item = array[i];
    // ...
    break;
    // ...
}

Second translation: the for and break is translated into an easier equivalent:

int i=0;
while (i < array.Length)
{
    var item = array[i];
    // ...
    break;
    // ...
    ++i;
}

And third translation (this is the equivalent of the IL code): we change break and while into a branch:

    int i=0; // for initialization

startLoop:
    if (i >= array.Length) // for condition
    {
        goto exitLoop;
    }
    var item = array[i];
    // ...
    goto exitLoop; // break
    // ...
    ++i;           // for post-expression
    goto startLoop; 

While the compiler does these things in a single step, it gives you insight into the process. The IL code that evolves from the C# program is the literal translation of the last C# code. You can see for yourself here: https://dotnetfiddle.net/QaiLRz (click 'view IL')

Now, one thing you have observed here is that during the process, the code becomes more complex. The easiest way to observe this is by the fact that we needed more and more code to ackomplish the same thing. You might also argue that foreach, for, while and break are actually short-hands for goto, which is partly true.

From IL to Assembler

The .NET JIT compiler is an SSA compiler. I won't go into all the details of SSA form here and how to create an optimizing compiler, it's just too much, but can give a basic understanding about what will happen. For a deeper understanding, it's best to start reading up on optimizing compilers (I do like this book for a brief introduction: http://ssabook.gforge.inria.fr/latest/book.pdf ) and LLVM (llvm.org).

Every optimizing compiler relies on the fact that code is easy and follows predictable patterns. In the case of FOR loops, we use graph theory to analyze branches, and then optimize things like cycli in our branches (e.g. branches backwards).

However, we now have forward branches to implement our loops. As you might have guessed, this is actually one of the first steps the JIT is going to fix, like this:

    int i=0; // for initialization

    if (i >= array.Length) // for condition
    {
        goto endOfLoop;
    }

startLoop:
    var item = array[i];
    // ...
    goto endOfLoop; // break
    // ...
    ++i;           // for post-expression

    if (i >= array.Length) // for condition
    {
        goto startLoop;
    }

endOfLoop:
    // ...

As you can see, we now have a backward branch, which is our little loop. The only thing that's still nasty here is the branch that we ended up with due to our break statement. In some cases, we can move this in the same way, but in others it's there to stay.

So why does the compiler do this? Well, if we can unroll the loop, we might be able to vectorize it. We might even be able to proof that there's just constants being added, which means our whole loop could vanish into thin air. To summarize: by making the patterns predictable (by making the branches predictable), we can proof that certain conditions hold in our loop, which means we can do magic during the JIT optimization.

However, branches tend to break those nice predictable patterns, which is something optimizers therefore kind-a dislike. Break, continue, goto - they all intend to break these predictable patterns- and are therefore not really 'nice'.

You should also realize at this point that a simple foreach is more predictable then a bunch of goto statements that go all over the place. In terms of (1) readability and (2) from an optimizer perspective, it's both the better solution.

Another thing worth mentioning is that it's very relevant for optimizing compilers to assign registers to variables (a process called register allocation). As you might know, there's only a finite number of registers in your CPU and they are by far the fastest pieces of memory in your hardware. Variables used in code that's in the inner-most loop, are more likely to get a register assigned, while variables outside of your loop are less important (because this code is probably hit less).

Help, too much complexity... what should I do?

The bottom line is that you should always use the language constructs you have at your disposal, which will usually (implictly) build predictable patterns for your compiler. Try to avoid strange branches if possible (specifically: break, continue, goto or a return in the middle of nothing).

The good news here is that these predictable patterns are both easy to read (for humans) and easy to spot (for compilers).

One of those patterns is called SESE, which stands for Single Entry Single Exit.

And now we get to the real question.

Imagine that you have something like this:

// a is a variable.

for (int i=0; i<100; ++i) 
{
  for (int j=0; j<100; ++j)
  {
     // ...

     if (i*j > a) 
     {
        // break everything
     }
  }
}

The easiest way to make this a predictable pattern is to simply eliminate the if completely:

int i, j;
for (i=0; i<100 && i*j <= a; ++i) 
{
  for (j=0; j<100 && i*j <= a; ++j)
  {
     // ...
  }
}

In other cases you can also split the method into 2 methods:

// Outer loop in method 1:

for (i=0; i<100 && processInner(i); ++i) 
{
}

private bool processInner(int i)
{
  int j;
  for (j=0; j<100 && i*j <= a; ++j)
  {
     // ...
  }
  return i*j<=a;
}

Temporary variables? Good, bad or ugly?

You might even decide to return a boolean from within the loop (but I personally prefer the SESE form because that's how the compiler will see it and I think it's cleaner to read).

Some people think it's cleaner to use a temporary variable, and propose a solution like this:

bool more = true;
for (int i=0; i<100; ++i) 
{
  for (int j=0; j<100; ++j) 
  {
     // ...
     if (i*j > a) { more = false; break; } // yuck.
     // ...
  }
  if (!more) { break; } // yuck.
  // ...
}
// ...

I personally am opposed to this approach. Look again on how the code is compiled. Now think about what this will do with these nice, predictable patterns. Get the picture?

Right, let me spell it out. What will happen is that:

• The compiler will write out everything as branches.
• As an optimization step, the compiler will do data flow analysis in an attempt to remove the strange more variable that only happens to be used in control flow.
• If succesful, the variable more will be eliminated from the program, and only branches remain. These branches will be optimized, so you will get only a single branch out of the inner loop.
• If unsuccesful, the variable more is definitely used in the inner-most loop, so if the compiler won't optimize it away, it has a high chance to be allocated to a register (which eats up valuable register memory).

So, to summarize: the optimizer in your compiler will go into a hell of a lot of trouble to figure out that more is only used for the control flow, and in the best case scenario will translate it to a single branch outside of the outer for loop.

In other words, the best case scenario is that it will end up with the equivalent of this:

for (int i=0; i<100; ++i) 
{
  for (int j=0; j<100; ++j)
  {
     // ...
     if (i*j > a) { goto exitLoop; } // perhaps add a comment
     // ...
  }
  // ...
}
exitLoop:

// ...

My personal opinion on this is quite simple: if this is what we intended all along, let's make the world easier for both the compiler and readability, and write that right away.

tl;dr:

Bottom line:

• Use a simple condition in your for loop if possible. Stick to the high-level language constructs you have at your disposal as much as possible.
• If everything fails and you're left with either goto or bool more, prefer the former.

const is for compile-time constants. You could just make it static readonly, but that would only apply to the METRICS variable itself (which should typically be Metrics instead, by .NET naming conventions). It wouldn't make the list immutable - so someone could call METRICS.Add("shouldn't be here");

You may want to use a ReadOnlyCollection<T> to wrap it. For example:

public static readonly IList<String> Metrics = new ReadOnlyCollection<string>
    (new List<String> { 
         SourceFile.LoC, SourceFile.McCabe, SourceFile.NoM,
         SourceFile.NoA, SourceFile.FanOut, SourceFile.FanIn, 
         SourceFile.Par, SourceFile.Ndc, SourceFile.Calls });

ReadOnlyCollection<T> just wraps a potentially-mutable collection, but as nothing else will have access to the List<T> afterwards, you can regard the overall collection as immutable.

(The capitalization here is mostly guesswork - using fuller names would make them clearer, IMO.)

Whether you declare it as IList<string>, IEnumerable<string>, ReadOnlyCollection<string> or something else is up to you... if you expect that it should only be treated as a sequence, then IEnumerable<string> would probably be most appropriate. If the order matters and you want people to be able to access it by index, IList<T> may be appropriate. If you want to make the immutability apparent, declaring it as ReadOnlyCollection<T> could be handy - but inflexible.

If it happens that you don't need this htm characte &nbsp shile using str.replace(/(\r\n|\n|\r)/gm, "") you can use this str.split('\n').join('');

There is GitPython. Haven’t heard of it before and internally, it relies on having the git executables somewhere; additionally, they might have plenty of bugs. But it could be worth a try.

How to clone:

import git
git.Git("/your/directory/to/clone").clone("git://gitorious.org/git-python/mainline.git")

(It’s not nice and I don’t know if it is the supported way to do it, but it worked.)

System.out.print("\"Hello\"");

The double quote character has to be escaped with a backslash in a Java string literal. Other characters that need special treatment include:

• Carriage return and newline: "\r" and "\n"
• Backslash: "\\\\"
• Single quote: "\'"
• Horizontal tab and form feed: "\t" and "\f"

The complete list of Java string and character literal escapes may be found in the section 3.10.6 of the JLS.

It is also worth noting that you can include arbitrary Unicode characters in your source code using Unicode escape sequences of the form "\uxxxx" where the "x"s are hexadecimal digits. However, these are different from ordinary string and character escapes in that you can use them anywhere in a Java program ... not just in string and character literals; see JLS sections 3.1, 3.2 and 3.3 for a details on the use of Unicode in Java source code.

You are using DictWriter.writerows() which expects a list of dicts, not a dict. You want DictWriter.writerow() to write a single row.

You will also want to use DictWriter.writeheader() if you want a header for you csv file.

You also might want to check out the with statement for opening files. It's not only more pythonic and readable but handles closing for you, even when exceptions occur.

Example with these changes made:

import csv

my_dict = {"test": 1, "testing": 2}

with open('mycsvfile.csv', 'w') as f:  # You will need 'wb' mode in Python 2.x
    w = csv.DictWriter(f, my_dict.keys())
    w.writeheader()
    w.writerow(my_dict)

Which produces:

test,testing
1,2

Adding custom button to navigation bar ( with image for buttonItem and specifying action method (void)openView{} and).

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0, 0, 32, 32);
[button setImage:[UIImage imageNamed:@"settings_b.png"] forState:UIControlStateNormal];
[button addTarget:self action:@selector(openView) forControlEvents:UIControlEventTouchUpInside];

UIBarButtonItem *barButton=[[UIBarButtonItem alloc] init];
[barButton setCustomView:button];
self.navigationItem.rightBarButtonItem=barButton;

[button release];
[barButton release];

Or you could use lastIndexOf() method on String

String last = string.substring(string.lastIndexOf('-') + 1);

If you are using any IDE most likely the problem is that file was used by some process. Like your tomcat might be using the file. Try to identify that particular process and close it. That should solve your problem.

To fix your code you can simply change [Cov] to Cov.values, the first parameter of pd.DataFrame will become a multi-dimensional numpy array:

Cov = pd.read_csv("path/to/file.txt", sep='\t')
Frame=pd.DataFrame(Cov.values, columns = ["Sequence", "Start", "End", "Coverage"])
Frame.to_csv("path/to/file.txt", sep='\t')

But the smartest solution still is use pd.read_excel with header=None and names=columns_list.

Percent encoding. Replace the hash with %23.

you can do that

var filteredFileList = fileList.Where(fl => filterList.Contains(fl.ToString()));

You just need to use the Gradle Application plugin:

apply plugin:'application'
mainClassName = "org.gradle.sample.Main"

And then simply gradle run.

As Teresa points out, you can also configure mainClassName as a system property and run with a command line argument.

Based on @lijat, here is a simplified implementation. In my spring-based application I simply load this as a bean.

public static void configureLog4jFromSystemProperties()
{
  final String LOGGER_PREFIX = "log4j.logger.";

  for(String propertyName : System.getProperties().stringPropertyNames())
  {
    if (propertyName.startsWith(LOGGER_PREFIX)) {
      String loggerName = propertyName.substring(LOGGER_PREFIX.length());
      String levelName = System.getProperty(propertyName, "");
      Level level = Level.toLevel(levelName); // defaults to DEBUG
      if (!"".equals(levelName) && !levelName.toUpperCase().equals(level.toString())) {
        logger.error("Skipping unrecognized log4j log level " + levelName + ": -D" + propertyName + "=" + levelName);
        continue;
      }
      logger.info("Setting " + loggerName + " => " + level.toString());
      Logger.getLogger(loggerName).setLevel(level);
    }
  }
}

No, you're creating an array, but there's a big difference:

char *string = "Some CONSTANT string";
printf("%c\n", string[1]);//prints o
string[1] = 'v';//INVALID!!

The array is created in a read only part of memory, so you can't edit the value through the pointer, whereas:

char string[] = "Some string";

creates the same, read only, constant string, and copies it to the stack array. That's why:

string[1] = 'v';

Is valid in the latter case.
If you write:

char string[] = {"some", " string"};

the compiler should complain, because you're constructing an array of char arrays (or char pointers), and assigning it to an array of chars. Those types don't match up. Either write:

char string[] = {'s','o','m', 'e', ' ', 's', 't','r','i','n','g', '\o'};
//this is a bit silly, because it's the same as char string[] = "some string";
//or
char *string[] = {"some", " string"};//array of pointers to CONSTANT strings
//or
char string[][10] = {"some", " string"};

Where the last version gives you an array of strings (arrays of chars) that you actually can edit...

foreach my $key (keys %$ad_grp_ref) {
    ...
}

Perl::Critic and daxim recommend the style

foreach my $key (keys %{ $ad_grp_ref }) {
    ...
}

out of concerns for readability and maintenance (so that you don't need to think hard about what to change when you need to use %{ $ad_grp_obj[3]->get_ref() } instead of %{ $ad_grp_ref })

With Java 7 you can use

if (Objects.equals(foo, null)) {
    ...
}

which will return true if both parameters are null.

For spinners based on a CursorAdapter:

• get the selected item id: spinner.getSelectedItemId()

• fetch the item name from your database, for example:

  public String getCountryName(int pId){
      Cursor cur = mDb.query(TABLE, new String[]{COL_NAME}, COL_ID+"=?", new String[]{pId+""}, null, null, null);
      String ret = null;
      if(cur.moveToFirst()){
          ret = cur.getString(0);
      }
      cur.close();
      return ret;
  }
  

The whole point of a class is that you create an instance, and that instance encapsulates a set of data. So it's wrong to say that your variables are global within the scope of the class: say rather that an instance holds attributes, and that instance can refer to its own attributes in any of its code (via self.whatever). Similarly, any other code given an instance can use that instance to access the instance's attributes - ie instance.whatever.

Have a look on this: https://stackoverflow.com/a/8558249/450148

It works only for few tags.

There is a getch() function in the ncurses library. You can get it by installing the ncurses-dev package.

tar -zcvf compressFileName.tar.gz folderToCompress

everything in folderToCompress will go to compressFileName

Edit: After review and comments I realized that people may get confused with compressFileName without an extension. If you want you can use .tar.gz extension(as suggested) with the compressFileName

There's no built in equivalent to that function you want.

You can write your own function that converts to .lower() each character at a time to avoid duplicating both strings, but I'm sure it will very cpu-intensive and extremely inefficient.

Unless you are working with extremely long strings (so long that can cause a memory problem if duplicated) then I would keep it simple and use

str1.lower() == str2.lower()

You'll be ok

You can use form.get to get the specific control object and use setValue

this.form.get(<formControlName>).setValue(<newValue>);

I find the simple solution

pylab.ticklabel_format(axis='y',style='sci',scilimits=(1,4))

Merge - HEAD branch will generate a new commit, preserving the ancestry of each commit history. History can become polluted if merge commits are made by multiple people who work on the same branch in parallel.

Rebase - Re-writes the changes of one branch onto another without creating a new commit. The code history is simplified, linear and readable but it doesn't work with pull requests, because you can't see what minor changes someone made.

I would use git merge when dealing with feature-based workflow or if I am not familiar with rebase. But, if I want a more a clean, linear history then git rebase is more appropriate. For more details be sure to check out this merge or rebase article.

This page on MSDN lists standard DateTime format strings, uncluding strings using the 'Z'.

Update: you will need to make sure that the rest of the date string follows the correct pattern as well (you have not supplied an example of what you send it, so it's hard to say whether you did or not). For the UTC format to work it should look like this:

// yyyy'-'MM'-'dd HH':'mm':'ss'Z'
DateTime utcTime = DateTime.Parse("2009-05-07 08:17:25Z");

Two simple examples to capture output the pwd command:

$ b=$(pwd)
$ echo $b
/home/user1

or

$ a=`pwd`
$ echo $a
/home/user1

The first way is preferred. Note that there can't be any spaces after the = for this to work.

Example using a short script:

#!/bin/bash

echo "hi there"

then:

$ ./so.sh
hi there
$ a=$(so.sh)
$ echo $a
hi there

In general a more flexible approach would be to return an exit value from the command and use it for further processing, though sometimes we just may want to capture the simple output from a command.

Sorry a bit late to the party and a bit surprised that nobody mentioned the drop method:

I've just bumped into this same problem when listening for onMouseLeave events on a disabled button. I worked around it by listening for the native mouseleave event on an element that wraps the disabled button.

componentDidMount() {
    this.watchForNativeMouseLeave();
},
componentDidUpdate() {
    this.watchForNativeMouseLeave();
},
// onMouseLeave doesn't work well on disabled elements
// https://github.com/facebook/react/issues/4251
watchForNativeMouseLeave() {
    this.refs.hoverElement.addEventListener('mouseleave', () => {
        if (this.props.disabled) {
            this.handleMouseOut();
        }
    });
},
render() {
    return (
        <span ref='hoverElement'
            onMouseEnter={this.handleMouseEnter}
            onMouseLeave={this.handleMouseLeave}
        >
            <button disabled={this.props.disabled}>Submit</button>
        </span>
    );
}

It's very similar to the accepted Answer.

@Amit's answer is good because it will work in both Mustache and Handlebars.

As far as Handlebars-only solutions, I've seen a few and I like the each_with_key block helper at https://gist.github.com/1371586 the best.

• It allows you to iterate over object literals without having to restructure them first, and
• It gives you control over what you call the key variable. With many other solutions you have to be careful about using object keys named 'key', or 'property', etc.

If you want to do this with 2 queries, you can always do something similar to this:

1) grab ids from the table with:

SELECT group_concat(id) as csv_result FROM your_table WHERE whatever = 'test' ...

Then copy result with mouse/keyboard or programming language to XXX below:

2) DELETE FROM your_table WHERE id IN ( XXX )

Maybe you could do this in one query, but this is what I prefer.

The reason this puts NaN into a column is because df.index and the Index of your right-hand-side object are different. @zach shows the proper way to assign a new column of zeros. In general, pandas tries to do as much alignment of indices as possible. One downside is that when indices are not aligned you get NaN wherever they aren't aligned. Play around with the reindex and align methods to gain some intuition for alignment works with objects that have partially, totally, and not-aligned-all aligned indices. For example here's how DataFrame.align() works with partially aligned indices:

In [7]: from pandas import DataFrame

In [8]: from numpy.random import randint

In [9]: df = DataFrame({'a': randint(3, size=10)})

In [10]:

Here is a function based on @Pythonio's answer. I encapsulate it into a function that automatically detects which backend is it using and do the corresponding actions.

def plt_set_fullscreen():
    backend = str(plt.get_backend())
    mgr = plt.get_current_fig_manager()
    if backend == 'TkAgg':
        if os.name == 'nt':
            mgr.window.state('zoomed')
        else:
            mgr.resize(*mgr.window.maxsize())
    elif backend == 'wxAgg':
        mgr.frame.Maximize(True)
    elif backend == 'Qt4Agg':
        mgr.window.showMaximized()

var newData = [1,2,3,4,5,6,7];
var chart = $('#chartjs').highcharts();
chart.series[0].setData(newData, true);

Explanation:
Variable newData contains value that want to update in chart. Variable chart is an object of a chart. setData is a method provided by highchart to update data.

Method setData contains two parameters, in first parameter we need to pass new value as array and second param is Boolean value. If true then chart updates itself and if false then we have to use redraw() method to update chart (i.e chart.redraw();)

@SpringBootApplication
@EnableAutoConfiguration

The @SpringBootApplication annotation includes @EnableAutoConfiguration by default.

Try using ifconfig -a. Look for "inet xxx.xxx.xxx.xxx", that is your IP address

maybe not the most efficient, but reads data in one line:

#include<iostream>
#include<vector>
#include<iterator>

main(int argc,char *argv[]){
  // read standard input into vector:
  std::vector<char>v(std::istream_iterator<char>(std::cin),
                     std::istream_iterator<char>());
  std::cout << "read " << v.size() << "chars\n";
}

It doesn't look like there's any built-in way to do it in insert mode, which was the question. Some of the other answers are correct for normal mode, as well as pointing out that a custom mapping could be created to add the functionality in insert mode.

Honestly, you should probably do most of your deleting in normal mode. ^W is neat to know about but I'm not sure I can think of a situation where I'd rather do it than esc to go into normal mode and have the more powerful deletion commands at my disposal.

Vim is very different from a number of other editors (including TextMate) in this way. If you're using it productively, you'll probably find that you don't spend very much time in insert mode.

Once I updated my Java version to 8 as suggested by browser. However I had selected to uninstall previous Java 6 version I have been used for coding my projects. When I enter the command in "java -version" in cmd it showed 1.8 and I could not start eclipse IDE run on Java 1.6.

When I installed Java 8 update for the browser it had changed the "PATH" System variable appending "C:\ProgramData\Oracle\Java\javapath" to the beginning. Newly added path pointed to Java vesion 8. So I removed that path from "PATH" System variable and everything worked fine. :)

That's because you shouldn't do it (at least with an immutable list). If you really really need to append an element to the end of a data structure and this data structure really really needs to be a list and this list really really has to be immutable then do eiher this:

(4 :: List(1,2,3).reverse).reverse

or that:

List(1,2,3) ::: List(4)

To disable auto activation of conda base environment in terminal:

conda config --set auto_activate_base false

To activate conda base environment:

conda activate

i think the best solution is disabling with css. You define a new class and you turn off the mouse events on it:

.disabledTab{
    pointer-events: none;
}

And then you assign this class to the desired li element:

<li class="disabled disabledTab"><a href="#"> .... </a></li>

You can add/remove the class with jQuery also. For example, to disable all tabs:

$("ul.nav li").removeClass('active').addClass('disabledTab');

Here is an example: jsFiddle

Here's my pure JavaScript solution that works if it's hidden inside a scrollable container too.

Demo here (try resizing the window too)

var visibleY = function(el){
  var rect = el.getBoundingClientRect(), top = rect.top, height = rect.height, 
    el = el.parentNode
  // Check if bottom of the element is off the page
  if (rect.bottom < 0) return false
  // Check its within the document viewport
  if (top > document.documentElement.clientHeight) return false
  do {
    rect = el.getBoundingClientRect()
    if (top <= rect.bottom === false) return false
    // Check if the element is out of view due to a container scrolling
    if ((top + height) <= rect.top) return false
    el = el.parentNode
  } while (el != document.body)
  return true
};

EDIT 2016-03-26: I've updated the solution to account for scrolling past the element so it's hidden above the top of the scroll-able container. EDIT 2018-10-08: Updated to handle when scrolled out of view above the screen.

To write it with a while loop you can do:

ls -f /var | while read -r file; do cmd $file; done

The primary disadvantage of this is that cmd is run in a subshell, which causes some difficulty if you are trying to set variables. The main advantages are that the shell does not need to load all of the filenames into memory, and there is no globbing. When you have a lot of files in the directory, those advantages are important (that's why I use -f on ls; in a large directory ls itself can take several tens of seconds to run and -f speeds that up appreciably. In such cases 'for file in /var/*' will likely fail with a glob error.)

Another good solution. You need create a file typings.json in root directory of project with content:

{
  "globalDependencies": {
    "core-js": "registry:dt/core-js#0.0.0+20160725163759",
    "jasmine": "registry:dt/jasmine#2.2.0+20160621224255",
    "node": "registry:dt/node#6.0.0+20160909174046"
  }
}

Then install global or local typings package, if it not installed (i am install it global):

sudo npm install --global typings

In project root directory run command:

typings install

After that problem is solved. Not needed to change tsconfig target to es6 or es7. Your web application do not support after that some old version of browsers.

The question is already answered (BTW, really good and comprehensive answer provided by Ben), but I would like to add another element for completeness, which may be also very handy.

In the example suggested by Ben:

<select ng-model="blah" ng-options="item.ID as item.Title for item in items"></select>

the following ngOptions form has been used: select as label for value in array.

Label is an expression, which result will be the label for <option> element. In that case you can perform certain string concatenations, in order to have more complex option labels.

Examples:

• ng-options="item.ID as item.Title + ' - ' + item.ID for item in items" gives you labels like Title - ID
• ng-options="item.ID as item.Title + ' (' + item.Title.length + ')' for item in items" gives you labels like Title (X), where X is length of Title string.

You can also use filters, for example,

• ng-options="item.ID as item.Title + ' (' + (item.Title | uppercase) + ')' for item in items" gives you labels like Title (TITLE), where Title value of Title property and TITLE is the same value but converted to uppercase characters.
• ng-options="item.ID as item.Title + ' (' + (item.SomeDate | date) + ')' for item in items" gives you labels like Title (27 Sep 2015), if your model has a property SomeDate
