What works in our project is what Archimedes Trajano wrote, but we had in our .m2/settings.xml something like this:

 <mirror>
  <id>nexus</id>
  <mirrorOf>*</mirrorOf>
  <url>http://url_to_our_repository</url>
 </mirror>

and the * should be changed to central. So if his answer doesn't work for you, you should check your settings.xml

function sample() {
    alert("This is sample function");
}

$(function() {
    $("#button").click(function() {
        setTimeout(sample, 2000);
    });

});

jsFiddle.

If you want to encapsulate sample() there, wrap the whole thing in a self invoking function (function() { ... })().

I ran into this issue when attempting to write to the default database provided in the asp.net mvc template. This was due to the fact that the database hadn't been created yet.

To create the database and make sure that it is accessible follow these steps:

1. Open up the Package manager console in Visual Studio
2. Run the command "update-database"

This will create the database an run all the necessary migrations on it.

JS does not have a sleep function, it has setTimeout() or setInterval() functions.

If you can move the code that you need to run after the pause into the setTimeout() callback, you can do something like this:

//code before the pause
setTimeout(function(){
    //do what you need here
}, 2000);

see example here : http://jsfiddle.net/9LZQp/

This won't halt the execution of your script, but due to the fact that setTimeout() is an asynchronous function, this code

console.log("HELLO");
setTimeout(function(){
    console.log("THIS IS");
}, 2000);
console.log("DOG");

will print this in the console:

HELLO
DOG
THIS IS

(note that DOG is printed before THIS IS)

You can use the following code to simulate a sleep for short periods of time:

function sleep(milliseconds) {
  var start = new Date().getTime();
  for (var i = 0; i < 1e7; i++) {
    if ((new Date().getTime() - start) > milliseconds){
      break;
    }
  }
}

now, if you want to sleep for 1 second, just use:

sleep(1000);

example: http://jsfiddle.net/HrJku/1/

please note that this code will keep your script busy for n milliseconds. This will not only stop execution of Javascript on your page, but depending on the browser implementation, may possibly make the page completely unresponsive, and possibly make the entire browser unresponsive. In other words this is almost always the wrong thing to do.

Official Documentation is here:

To build a debug APK, open a command line and navigate to the root of your project directory. To initiate a debug build, invoke the assembleDebug task:

gradlew assembleDebug

This creates an APK named module_name-debug.apk in project_name/module_name/build/outputs/apk/.

I know this is an old post, but I thought the tracking of mouse button using mouse up/down felt a bit clunky, so I found an alternative that may appeal to some.

<style>
    div.myDiv:active {
        cursor: default;
    }
</style>

<script>
    function handleMove( div ) {
        var style = getComputedStyle( div );
        if (style.getPropertyValue('cursor') == 'default')
        {
            // You're down and moving here!
        }
    }
</script>

<div class='myDiv' onmousemove='handleMove(this);'>Click and drag me!</div>

The :active selector handles the mouse click much better than mouse up/down, you just need a way of reading that state in the onmousemove event. For that I needed to cheat and relied on the fact that the default cursor is "auto" and I just change it to "default", which is what auto selects by default.

You can use anything in the object that is returned by getComputedStyle that you can use as a flag without upsetting the look of your page e.g. border-color.

I would have liked to set my own user defined style in the :active section, but I couldn't get that to work. It would be better if it's possible.

Basically, flush() cleans out your RAM buffer, its real power is that it lets you continue to write to it afterwards - but it shouldn't be thought of as the best/safest write to file feature. It's flushing your RAM for more data to come, that is all. If you want to ensure data gets written to file safely then use close() instead.

FYI: The other solutions will only log statements from the default database—usually postgres—to log others; start with their solution; then:

ALTER DATABASE your_database_name
SET log_statement = 'all';

Use a HashSet along with your List:

List<string> myList = new List<string>();
HashSet<string> myHashSet = new HashSet<string>();

public void addToList(string s) {
    if (myHashSet.Add(s)) {
        myList.Add(s);
    }
}

myHashSet.Add(s) will return true if s is not exist in it.

using System.Linq;

string s = string.Join(";", myDict.Select(x => x.Key + "=" + x.Value).ToArray());

(And if you're using .NET 4, or newer, then you can omit the final ToArray call.)

Add this to your CSS:

ul { list-style-position: inside; }

This will place the li elements in the same indent as other paragraphs and text.

Go to view all content of the site (http://yourdmain.sharepoint/sitename/_layouts/viewlsts.aspx). Select the document library "Pages" (the "Pages" library are named based on the language you created the site in. I.E. in norwegian the library is named "Sider"). Download the default.aspx to you computer and fix it (remove the web part and the <%Register tag). Save it and upload it back to the library (remember to check in the file).

EDIT:

ahh.. you are not using a publishing site template. Go to site action -> site settings. Under "site administration" select the menu "content and structure" you should now see your default.aspx page. But you cant do much with it...(delete, copy or move)

workaround: Enable publishing feature to the root web. Add the fixed default.aspx file to the Pages library and change the welcome page to this. Disable the publishing feature (this will delete all other list create from this feature but not the Pages library since one page is in use.). You will now have a new default.aspx page for the root web but the url is changed from sitename/default.aspx to sitename/Pages/default.aspx.

workaround II Use a feature to change the default.aspx file. The solution is explained here: http://wssguy.com/blogs/dan/archive/2008/10/29/how-to-change-the-default-page-of-a-sharepoint-site-using-a-feature.aspx

I have read that it is used for optimizing but is not clearly defined in any standard.

In fact it is clearly defined by the C standard. Quoting the N1570 draft section 6.7.1 paragraph 6 (other versions have the same wording):

A declaration of an identifier for an object with storage-class specifier register suggests that access to the object be as fast as possible. The extent to which such suggestions are effective is implementation-defined.

The unary & operator may not be applied to an object defined with register, and register may not be used in an external declaration.

There are a few other (fairly obscure) rules that are specific to register-qualified objects:

• Defining an array object with register has undefined behavior.
  Correction: It's legal to define an array object with register, but you can't do anything useful with such an object (indexing into an array requires taking the address of its initial element).
• The _Alignas specifier (new in C11) may not be applied to such an object.
• If the parameter name passed to the va_start macro is register-qualified, the behavior is undefined.

There may be a few others; download a draft of the standard and search for "register" if you're interested.

As the name implies, the original meaning of register was to require an object to be stored in a CPU register. But with improvements in optimizing compilers, this has become less useful. Modern versions of the C standard don't refer to CPU registers, because they no longer (need to) assume that there is such a thing (there are architectures that don't use registers). The common wisdom is that applying register to an object declaration is more likely to worsen the generated code, because it interferes with the compiler's own register allocation. There might still be a few cases where it's useful (say, if you really do know how often a variable will be accessed, and your knowledge is better than what a modern optimizing compiler can figure out).

The main tangible effect of register is that it prevents any attempt to take an object's address. This isn't particularly useful as an optimization hint, since it can be applied only to local variables, and an optimizing compiler can see for itself that such an object's address isn't taken.

If you use:

if (Array[i].compareToIgnoreCase(Array[j]) < 0)

you will get:

Example  Hello  is  Sorting  This

which I think is the output you were looking for.

A better solution would be you use in style css, the command to break lines. Works in older versions of browsers.

p {
word-wrap: break-word;
}

I haven't seen the answer already here among the mess of custom Regex answers, but...

There exists a python library called py3-validate-email validate_email which has 3 levels of email validation, including asking a valid SMTP server if the email address is valid (without sending an email).

To install

python -m pip install py3-validate-email

Basic usage:

from validate_email import validate_email
is_valid = validate_email(email_address='[email protected]', \
    check_regex=True, check_mx=True, \
    from_address='[email protected]', helo_host='my.host.name', \ 
    smtp_timeout=10, dns_timeout=10, use_blacklist=True)

For those interested in the dirty details, validate_email.py (source) aims to be faithful to RFC 2822.

All we are really doing is comparing the input string to one gigantic regular expression. But building that regexp, and ensuring its correctness, is made much easier by assembling it from the "tokens" defined by the RFC. Each of these tokens is tested in the accompanying unit test file.

you may need the pyDNS module for checking SMTP servers

pip install pyDNS

apt-get install python3-dns

This website contains a much cleaner solution, it leaves pip intact as-well and one can easily switch between 3.5 and 3.6 and then whenever 3.7 is released.

http://ubuntuhandbook.org/index.php/2017/07/install-python-3-6-1-in-ubuntu-16-04-lts/

A short summary:

sudo apt-get install python python-pip python3 python3-pip
sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
sudo apt-get install python3.6
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2

Then

$ pip -V
pip 8.1.1 from /usr/lib/python2.7/dist-packages (python 2.7)
$ pip3 -V
pip 8.1.1 from /usr/local/lib/python3.5/dist-packages (python 3.5)

Then to select python 3.6 run

sudo update-alternatives --config python3

and select '2'. Then

$ pip3 -V
pip 8.1.1 from /usr/local/lib/python3.6/dist-packages (python 3.6)

To update pip select the desired version and

pip3 install --upgrade pip

$ pip3 -V
pip 9.0.1 from /usr/local/lib/python3.6/dist-packages (python 3.6)

Tested on Ubuntu 16.04.

Yes, take a look at this thread which talks about the differences between platforms.

How to detect right-click event for Mac OS

BUTTON3 is the same across all platforms, being equal to the right mouse button. BUTTON2 is simply ignored if the middle button does not exist.

You can't do insert into to insert single record. It's not supported by Hive. You may place all new records that you want to insert in a file and load that file into a temp table in Hive. Then using insert overwrite..select command insert those rows into a new partition of your main Hive table. The constraint here is your main table will have to be pre partitioned. If you don't use partition then your whole table will be replaced with these new records.

Here is somewhat old-fashioned solution:

/*
    Splits string into parts delimitered with specified character.
*/
CREATE FUNCTION [dbo].[SDF_SplitString]
(
    @sString nvarchar(2048),
    @cDelimiter nchar(1)
)
RETURNS @tParts TABLE ( part nvarchar(2048) )
AS
BEGIN
    if @sString is null return
    declare @iStart int,
            @iPos int
    if substring( @sString, 1, 1 ) = @cDelimiter 
    begin
        set @iStart = 2
        insert into @tParts
        values( null )
    end
    else 
        set @iStart = 1
    while 1=1
    begin
        set @iPos = charindex( @cDelimiter, @sString, @iStart )
        if @iPos = 0
            set @iPos = len( @sString )+1
        if @iPos - @iStart > 0          
            insert into @tParts
            values  ( substring( @sString, @iStart, @iPos-@iStart ))
        else
            insert into @tParts
            values( null )
        set @iStart = @iPos+1
        if @iStart > len( @sString ) 
            break
    end
    RETURN

END

In SQL Server 2008 you can achieve the same with .NET code. Maybe it would work faster, but definitely this approach is easier to manage.

create an array of ones; multiply each list times the array; convert array to a list

import numpy as np

a = [1,2,3,4]
b = [2,3,4,5]

c = (np.ones(len(a))*a*b).tolist()

[2.0, 6.0, 12.0, 20.0]

You cannot use function calls in a class construction, you should initialize that value in the constructor function.

From the PHP Manual on class properties:

This declaration may include an initialization, but this initialization must be a constant value--that is, it must be able to be evaluated at compile time and must not depend on run-time information in order to be evaluated.

A working code sample:

<?php
    class UserDatabaseConnection
    {
        public $connection;
        public function __construct()
        {
            $this->connection = sqlite_open("[path]/data/users.sqlite", 0666);
        }
        public function lookupUser($username)
        {
            // rest of my code...
            // example usage (procedural way):
            $query = sqlite_exec($this->connection, "SELECT ...", $error);
            // object oriented way:
            $query = $this->connection->queryExec("SELECT ...", $error);
        }
    }

    $udb = new UserDatabaseConnection;
?>

Depending on your needs, protected or private might be a better choice for $connection. That protects you from accidentally closing or messing with the connection.

There are methods like WriteAllText in the File class for common operations on files.

Use the MapPath method to get the physical path for a file in your web application.

File.WriteAllText(Server.MapPath("~/data.txt"), TextBox1.Text);

replace it with index of the array.

array[index] = new_value;

Your javascript is executed before the HTML is generated, so it doesn't "see" the ungenerated INPUT elements. For jQuery, you would either stick the Javascript at the end of the HTML or wrap it like this:

<script type="text/javascript">   $(function() { //jQuery trick to say after all the HTML is parsed.     $("input[type=radio]").click(function() {       var total = 0;       $("input[type=radio]:checked").each(function() {         total += parseFloat($(this).val());       });        $("#totalSum").val(total);     });   }); </script> 

EDIT: This code works for me

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body>   <strong>Choose a base package:</strong>   <input id="item_0" type="radio" name="pkg" value="1942" />Base Package 1 - $1942   <input id="item_1" type="radio" name="pkg" value="2313" />Base Package 2 - $2313   <input id="item_2" type="radio" name="pkg" value="2829" />Base Package 3 - $2829   <strong>Choose an add on:</strong>   <input id="item_10" type="radio" name="ext" value="0" />No add-on - +$0   <input id="item_12" type="radio" name="ext" value="2146" />Add-on 1 - (+$2146)   <input id="item_13" type="radio" name="ext" value="2455" />Add-on 2 - (+$2455)   <input id="item_14" type="radio" name="ext" value="2764" />Add-on 3 - (+$2764)   <input id="item_15" type="radio" name="ext" value="3073" />Add-on 4 - (+$3073)   <input id="item_16" type="radio" name="ext" value="3382" />Add-on 5 - (+$3382)   <input id="item_17" type="radio" name="ext" value="3691" />Add-on 6 - (+$3691)   <strong>Your total is:</strong>   <input id="totalSum" type="text" name="totalSum" readonly="readonly" size="5" value="" />   <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>   <script type="text/javascript">       $("input[type=radio]").click(function() {         var total = 0;         $("input[type=radio]:checked").each(function() {           total += parseFloat($(this).val());         });          $("#totalSum").val(total);       });     </script> </body> </html> 

I posted a similar issue here, working with a SQL 2012 db hosted on Amazon RDS. The problem was in the connection string - I had "Application Name" and "App" properties in there. Once I removed those, it worked.

Use namespace

using System.Collections.Specialized;

Make instance of DataContext Class

LinqToSqlDataContext dc = new LinqToSqlDataContext();

Use

OrderedDictionary dict = dc.TableName.ToDictionary(d => d.key, d => d.value);

In order to retrieve the values use namespace

   using System.Collections;

ICollection keyCollections = dict.Keys;
ICOllection valueCollections = dict.Values;

String[] myKeys = new String[dict.Count];
String[] myValues = new String[dict.Count];

keyCollections.CopyTo(myKeys,0);
valueCollections.CopyTo(myValues,0);

for(int i=0; i<dict.Count; i++)
{
Console.WriteLine("Key: " + myKeys[i] + "Value: " + myValues[i]);
}
Console.ReadKey();

You Can use below Simple Code:

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

Example for Using:

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

You shouldn't rely on the order of elements by using prev or next. Just use the for attribute of the label, as it should correspond to the ID of the element you're currently manipulating:

var label = $("label[for='" + $(this).attr('id') + "']");

However, there are some cases where the label will not have for set, in which case the label will be the parent of its associated control. To find it in both cases, you can use a variation of the following:

var label = $('label[for="' + $(this).attr('id') + '"]');

if(label.length <= 0) {
    var parentElem = $(this).parent(),
        parentTagName = parentElem.get(0).tagName.toLowerCase();

    if(parentTagName == "label") {
        label = parentElem;
    }
}

I hope this helps!

Python >= 3.5 alternative: unpack into a list literal [*newdict]

New unpacking generalizations (PEP 448) were introduced with Python 3.5 allowing you to now easily do:

>>> newdict = {1:0, 2:0, 3:0}
>>> [*newdict]
[1, 2, 3]

Unpacking with * works with any object that is iterable and, since dictionaries return their keys when iterated through, you can easily create a list by using it within a list literal.

Adding .keys() i.e [*newdict.keys()] might help in making your intent a bit more explicit though it will cost you a function look-up and invocation. (which, in all honesty, isn't something you should really be worried about).

_{The *iterable syntax is similar to doing list(iterable) and its behaviour was initially documented in the Calls section of the Python Reference manual. With PEP 448 the restriction on where *iterable could appear was loosened allowing it to also be placed in list, set and tuple literals, the reference manual on Expression lists was also updated to state this.}

Though equivalent to list(newdict) with the difference that it's faster (at least for small dictionaries) because no function call is actually performed:

%timeit [*newdict]
1000000 loops, best of 3: 249 ns per loop

%timeit list(newdict)
1000000 loops, best of 3: 508 ns per loop

%timeit [k for k in newdict]
1000000 loops, best of 3: 574 ns per loop

with larger dictionaries the speed is pretty much the same (the overhead of iterating through a large collection trumps the small cost of a function call).

In a similar fashion, you can create tuples and sets of dictionary keys:

>>> *newdict,
(1, 2, 3)
>>> {*newdict}
{1, 2, 3}

beware of the trailing comma in the tuple case!

I'd very simply:

• Open the file for read/write
• Read/seek through it until the start of the line you want to delete
• Set the write pointer to the current read pointer
• Read through to the end of the line we're deleting and skip the newline delimiters (counting the number of characters as we go, we'll call it nline)
• Read byte-by-byte and write each byte to the file
• When finished truncate the file to (orig_length - nline).

You need add -> contentType: "application/json; charset=utf-8",

<script type="text/javascript">
    $(document).ready( function() {
      $('#btnTest').click( function() {
        $.ajax({
          type: "POST", 
          url: "/Login/Test",
          data: { ListID: '1', ItemName: 'test' },
          dataType: "json",
          contentType: "application/json; charset=utf-8",
          success: function(response) { alert(response); },
          error: function(xhr, ajaxOptions, thrownError) { alert(xhr.responseText); }
        });
      });
    });
</script>

Adding this answer as I had to lookup multiple places to achieve my use case. I had a script that runs on startup.

/sbin/startproc -u myUser $JAVA_HOME/bin/java

The pipe character | has a special meaning in regular expressions. a|b means "match either a or b". If you want to match a literal | character, you need to escape it:

... | Select-String -Pattern 'H\|159' -NotMatch | ...

Neither $scope.$evalAsync() or $timeout(fn, 0) worked reliably for me.

I had to combine the two. I made a directive and also put a priority higher than the default value for good measure. Here's a directive for it (Note I use ngInject to inject dependencies):

app.directive('postrenderAction', postrenderAction);

/* @ngInject */
function postrenderAction($timeout) {
    // ### Directive Interface
    // Defines base properties for the directive.
    var directive = {
        restrict: 'A',
        priority: 101,
        link: link
    };
    return directive;

    // ### Link Function
    // Provides functionality for the directive during the DOM building/data binding stage.
    function link(scope, element, attrs) {
        $timeout(function() {
            scope.$evalAsync(attrs.postrenderAction);
        }, 0);
    }
}

To call the directive, you would do this:

<div postrender-action="functionToRun()"></div>

If you want to call it after an ng-repeat is done running, I added an empty span in my ng-repeat and ng-if="$last":

<li ng-repeat="item in list">
    <!-- Do stuff with list -->
    ...

    <!-- Fire function after the last element is rendered -->
    <span ng-if="$last" postrender-action="$ctrl.postRender()"></span>
</li>

SignalR provides ConnectionId for each connection. To find which connection belongs to whom (the user), we need to create a mapping between the connection and the user. This depends on how you identify a user in your application.

In SignalR 2.0, this is done by using the inbuilt IPrincipal.Identity.Name, which is the logged in user identifier as set during the ASP.NET authentication.

However, you may need to map the connection with the user using a different identifier instead of using the Identity.Name. For this purpose this new provider can be used with your custom implementation for mapping user with the connection.

Example of Mapping SignalR Users to Connections using IUserIdProvider

Lets assume our application uses a userId to identify each user. Now, we need to send message to a specific user. We have userId and message, but SignalR must also know the mapping between our userId and the connection.

To achieve this, first we need to create a new class which implements IUserIdProvider:

public class CustomUserIdProvider : IUserIdProvider
{
     public string GetUserId(IRequest request)
    {
        // your logic to fetch a user identifier goes here.

        // for example:

        var userId = MyCustomUserClass.FindUserId(request.User.Identity.Name);
        return userId.ToString();
    }
}

The second step is to tell SignalR to use our CustomUserIdProvider instead of the default implementation. This can be done in the Startup.cs while initializing the hub configuration:

public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        var idProvider = new CustomUserIdProvider();

        GlobalHost.DependencyResolver.Register(typeof(IUserIdProvider), () => idProvider);          

        // Any connection or hub wire up and configuration should go here
        app.MapSignalR();
    }
}

Now, you can send message to a specific user using his userId as mentioned in the documentation, like:

public class MyHub : Hub
{
   public void Send(string userId, string message)
   {
      Clients.User(userId).send(message);
   }
}

Hope this helps.

type-specific formatting can be used as well:

t = datetime.datetime(2012, 2, 23, 0, 0)
"{:%m/%d/%Y}".format(t)

Output:

'02/23/2012'

This answer suggests that you cannot download files directly with AJAX, primarily for security reasons. So I'll describe what I do in this situation,

01. Add href attribute in your anchor tag inside the component.html file,
eg:-

<div>
       <a [href]="fileUrl" mat-raised-button (click)='getGenaratedLetterTemplate(element)'> GENARATE </a>
</div>

02. Do all following steps in your component.ts to bypass the security level and bring the save as popup dialog,
eg:-

import { environment } from 'environments/environment';
import { DomSanitizer } from '@angular/platform-browser';
export class ViewHrApprovalComponent implements OnInit {
private apiUrl = environment.apiUrl;
  fileUrl
 constructor(
    private sanitizer: DomSanitizer,
    private letterService: LetterService) {}
getGenaratedLetterTemplate(letter) {

    this.data.getGenaratedLetterTemplate(letter.letterId).subscribe(
      // cannot download files directly with AJAX, primarily for security reasons);
    console.log(this.apiUrl + 'getGeneratedLetter/' + letter.letterId);
    this.fileUrl = this.sanitizer.bypassSecurityTrustResourceUrl(this.apiUrl + 'getGeneratedLetter/' + letter.letterId);
  }

Note: This answer will work if you are getting an error "OK" with status code 200

You can just add a main function to resolve this problem. Just like:

int main()
{
    return 0;
}

Grand Performance Comparison

^{Scroll to the end for a TL;DR graph}

Since I had "nothing better to do" (understand: I had just a lot of work), I decided to do a little performance contest. I assembled the most sensible or interesting answers and did some simple timeit in CPython 3.5.1 on them. I tested them with only one string, which is a typical input in my case:

>>> s = 'ZDXMZKMXFDKXZFKZ'
>>> len(s)
16

Be aware that results might vary for different inputs, be it different length of the string or different number of distinct characters, or different average number of occurrences per character.

Don't reinvent the wheel

Python has made it simple for us. The collections.Counter class does exactly what we want and a lot more. Its usage is by far the simplest of all the methods mentioned here.

taken from @oefe, nice find

>>> timeit('Counter(s)', globals=locals())
8.208566107001388

Counter goes the extra mile, which is why it takes so long.

¿Dictionary, comprende?

Let's try using a simple dict instead. First, let's do it declaratively, using dict comprehension.

I came up with this myself...

>>> timeit('{c: s.count(c) for c in s}', globals=locals())
4.551155784000002

This will go through s from beginning to end, and for each character it will count the number of its occurrences in s. Since s contains duplicate characters, the above method searches s several times for the same character. The result is naturally always the same. So let's count the number of occurrences just once for each character.

I came up with this myself, and so did @IrshadBhat

>>> timeit('{c: s.count(c) for c in set(s)}', globals=locals())
3.1484066140001232

Better. But we still have to search through the string to count the occurrences. One search for each distinct character. That means we're going to read the string more than once. We can do better than that! But for that, we have to get off our declarativist high horse and descend into an imperative mindset.

Exceptional code

AKA Gotta catch 'em all!

inspired by @anthony

>>> timeit('''
... d = {}
... for c in s:
...   try:
...     d[c] += 1
...   except KeyError:
...     d[c] = 1
... ''', globals=locals())
3.7060273620008957

Well, it was worth a try. If you dig into the Python source (I can't say with certainty because I have never really done that), you will probably find that when you do except ExceptionType, Python has to check whether the exception raised is actually of ExceptionType or some other type. Just for the heck of it, let's see how long will it take if we omit that check and catch all exceptions.

made by @anthony

>>> timeit('''
... d = {}
... for c in s:
...   try:
...     d[c] += 1
...   except:
...     d[c] = 1
... ''', globals=locals())
3.3506563019982423

It does save some time, so one might be tempted to use this as some sort of optimization.
Don't do that! Or actually do. Do it now:

_{INTERLUDE 1}

import time
while True:
  try:
    time.sleep(1)
  except:
    print("You're trapped in your own trap!")

You see? It catches KeyboardInterrupt, besides other things. In fact, it catches all the exceptions there are. Including ones you might not have even heard about, like SystemExit.

_{INTERLUDE 2}

import sys
try:
  print("Goodbye. I'm going to die soon.")
  sys.exit()
except:
  print('BACK FROM THE DEAD!!!')

Now back to counting letters and numbers and other characters.

Playing catch-up

Exceptions aren't the way to go. You have to try hard to catch up with them, and when you finally do, they just throw up on you and then raise their eyebrows like it's your fault. Luckily brave fellows have paved our way so we can do away with exceptions, at least in this little exercise.

The dict class has a nice method – get – which allows us to retrieve an item from a dictionary, just like d[k]. Except when the key k is not in the dictionary, it can return a default value. Let's use that method instead of fiddling with exceptions.

credit goes to @Usman

>>> timeit('''
... d = {}
... for c in s:
...   d[c] = d.get(c, 0) + 1
... ''', globals=locals())
3.2133633289995487

Almost as fast as the set-based dict comprehension. On larger inputs, this one would probably be even faster.

Use the right tool for the job

For at least mildly knowledgeable Python programmer, the first thing that comes to mind is probably defaultdict. It does pretty much the same thing as the version above, except instead of a value, you give it a value factory. That might cause some overhead, because the value has to be "constructed" for each missing key individually. Let's see how it performs.

hope @AlexMartelli won't crucify me for from collections import defaultdict

>>> timeit('''
... dd = defaultdict(int)
... for c in s:
...   dd[c] += 1
... ''', globals=locals())
3.3430528169992613

Not that bad. I'd say the increase in execution time is a small tax to pay for the improved readability. However, we also favor performance, and we will not stop here. Let's take it further and prepopulate the dictionary with zeros. Then we won't have to check every time if the item is already there.

hats off to @sqram

>>> timeit('''
... d = dict.fromkeys(s, 0)
... for c in s:
...   d[c] += 1
... ''', globals=locals())
2.6081761489986093

That's good. Over three times as fast as Counter, yet still simple enough. Personally, this is my favorite in case you don't want to add new characters later. And even if you do, you can still do it. It's just less convenient than it would be in other versions:

d.update({ c: 0 for c in set(other_string) - d.keys() })

Practicality beats purity (except when it's not really practical)

Now a bit different kind of counter. @IdanK has come up with something interesting. Instead of using a hash table (a.k.a. dictionary a.k.a. dict), we can avoid the risk of hash collisions and consequent overhead of their resolution. We can also avoid the overhead of hashing the key, and the extra unoccupied table space. We can use a list. The ASCII values of characters will be indices and their counts will be values. As @IdanK has pointed out, this list gives us constant time access to a character's count. All we have to do is convert each character from str to int using the built-in function ord. That will give us an index into the list, which we will then use to increment the count of the character. So what we do is this: we initialize the list with zeros, do the job, and then convert the list into a dict. This dict will only contain those characters which have non-zero counts, in order to make it compliant with other versions.

As a side note, this technique is used in a linear-time sorting algorithm known as count sort or counting sort. It's very efficient, but the range of values being sorted is limited, since each value has to have its own counter. To sort a sequence of 32-bit integers, 4.3 billion counters would be needed.

>>> timeit('''
... counts = [0 for _ in range(256)]
... for c in s:
...   counts[ord(c)] += 1
... d = {chr(i): count for i,count in enumerate(counts) if count != 0}
... ''', globals=locals())
25.438595562001865

Ouch! Not cool! Let's try and see how long it takes when we omit building the dictionary.

>>> timeit('''
... counts = [0 for _ in range(256)]
... for c in s:
...   counts[ord(c)] += 1
... ''', globals=locals())
10.564866792999965

Still bad. But wait, what's [0 for _ in range(256)]? Can't we write it more simply? How about [0] * 256? That's cleaner. But will it perform better?

>>> timeit('''
... counts = [0] * 256
... for c in s:
...   counts[ord(c)] += 1
... ''', globals=locals())
3.290163638001104

Considerably. Now let's put the dictionary back in.

>>> timeit('''
... counts = [0] * 256
... for c in s:
...   counts[ord(c)] += 1
... d = {chr(i): count for i,count in enumerate(counts) if count != 0}
... ''', globals=locals())
18.000623562998953

Almost six times slower. Why does it take so long? Because when we enumerate(counts), we have to check every one of the 256 counts and see if it's zero. But we already know which counts are zero and which are not.

>>> timeit('''
... counts = [0] * 256
... for c in s:
...   counts[ord(c)] += 1
... d = {c: counts[ord(c)] for c in set(s)}
... ''', globals=locals())
5.826531438000529

It probably won't get much better than that, at least not for such a small input. Plus it's only usable for 8-bit EASCII characters. ? ?????!

And the winner is...

>>> timeit('''
... d = {}
... for c in s:
...   if c in d:
...     d[c] += 1
...   else:
...     d[c] = 1
... ''', globals=locals())
1.8509794599995075

Yep. Even if you have to check every time whether c is in d, for this input it's the fastest way. No pre-population of d will make it faster (again, for this input). It's a lot more verbose than Counter or defaultdict, but also more efficient.

That's all folks

This little exercise teaches us a lesson: when optimizing, always measure performance, ideally with your expected inputs. Optimize for the common case. Don't presume something is actually more efficient just because its asymptotic complexity is lower. And last but not least, keep readability in mind. Try to find a compromise between "computer-friendly" and "human-friendly".

UPDATE

I have been informed by @MartijnPieters of the function collections._count_elements available in Python 3.

Help on built-in function _count_elements in module _collections:

_count_elements(...)
    _count_elements(mapping, iterable) -> None

    Count elements in the iterable, updating the mappping

This function is implemented in C, so it should be faster, but this extra performance comes at a price. The price is incompatibility with Python 2 and possibly even future versions, since we're using a private function.

From the documentation:

[...] a name prefixed with an underscore (e.g. _spam) should be treated as a non-public part of the API (whether it is a function, a method or a data member). It should be considered an implementation detail and subject to change without notice.

That said, if you still want to save those 620 nanoseconds per iteration:

>>> timeit('''
... d = {}
... _count_elements(d, s)
... ''', globals=locals())
1.229239897998923

UPDATE 2: Large strings

I thought it might be a good idea to re-run the tests on some larger input, since a 16 character string is such a small input that all the possible solutions were quite comparably fast (1,000 iterations in under 30 milliseconds).

I decided to use the complete works of Shakespeare as a testing corpus, which turned out to be quite a challenge (since it's over 5MiB in size ). I just used the first 100,000 characters of it, and I had to limit the number of iterations from 1,000,000 to 1,000.

import urllib.request
url = 'https://ocw.mit.edu/ans7870/6/6.006/s08/lecturenotes/files/t8.shakespeare.txt'
s = urllib.request.urlopen(url).read(100_000)

collections.Counter was really slow on a small input, but the tables have turned

Counter(s)

=> 7.63926783799991

Naïve T(n²) time dictionary comprehension simply doesn't work

{c: s.count(c) for c in s}

=> 15347.603935000052s (tested on 10 iterations; adjusted for 1000)

Smart T(n) time dictionary comprehension works fine

{c: s.count(c) for c in set(s)}

=> 8.882608592999986

Exceptions are clumsy and slow

d = {}
for c in s:
  try:
    d[c] += 1
  except KeyError:
    d[c] = 1

=> 21.26615508399982

Omitting the exception type check doesn't save time (since the exception is only thrown a few times)

d = {}
for c in s:
  try:
    d[c] += 1
  except:
    d[c] = 1

=> 21.943328911999743

dict.get looks nice but runs slow

d = {}
for c in s:
  d[c] = d.get(c, 0) + 1

=> 28.530086210000007

collections.defaultdict isn't very fast either

dd = defaultdict(int)
for c in s:
  dd[c] += 1

=> 19.43012963199999

dict.fromkeys requires reading the (very long) string twice

d = dict.fromkeys(s, 0)
for c in s:
  d[c] += 1

=> 22.70960557699999

Using list instead of dict is neither nice nor fast

counts = [0 for _ in range(256)]
for c in s:
  counts[ord(c)] += 1

d = {chr(i): count for i,count in enumerate(counts) if count != 0}

=> 26.535474792000002

Leaving out the final conversion to dict doesn't help

counts = [0 for _ in range(256)]
for c in s:
  counts[ord(c)] += 1

=> 26.27811567400005

It doesn't matter how you construct the list, since it's not the bottleneck

counts = [0] * 256
for c in s:
  counts[ord(c)] += 1

=> 25.863524940000048

counts = [0] * 256
for c in s:
  counts[ord(c)] += 1

d = {chr(i): count for i,count in enumerate(counts) if count != 0}

=> 26.416733378000004

If you convert list to dict the "smart" way, it's even slower (since you iterate over the string twice)

counts = [0] * 256
for c in s:
  counts[ord(c)] += 1

d = {c: counts[ord(c)] for c in set(s)}

=> 29.492915620000076

The dict.__contains__ variant may be fast for small strings, but not so much for big ones

d = {}
for c in s:
  if c in d:
    d[c] += 1
  else:
    d[c] = 1

=> 23.773295123000025

collections._count_elements is about as fast as collections.Counter (which uses _count_elements internally)

d = {}
_count_elements(d, s)

=> 7.5814381919999505

Final verdict: Use collections.Counter unless you cannot or don't want to :)

Appendix: NumPy

The numpy package provides a method numpy.unique which accomplishes (almost) precisely what we want.

The way this method works is very different from all the above methods:

• It first sorts a copy of the input using Quicksort, which is an O(n²) time operation in the worst case, albeit O(n log n) on average and O(n) in the best case.

• Then it creates a "mask" array containing True at indices where a run of the same values begins, viz. at indices where the value differs from the previous value. Repeated values produce False in the mask. Example: [5,5,5,8,9,9] produces a mask [True, False, False, True, True, False].

• This mask is then used to extract the unique values from the sorted input - unique_chars in the code below. In our example, they would be [5, 8, 9].

• Positions of the True values in the mask are taken into an array, and the length of the input is appended at the end of this array. For the above example, this array would be [0, 3, 4, 6].

• For this array, differences between its elements are calculated, eg. [3, 1, 2]. These are the respective counts of the elements in the sorted array - char_counts in the code below.

• Finally, we create a dictionary by zipping unique_chars and char_counts: {5: 3, 8: 1, 9: 2}.

import numpy as np

def count_chars(s):
  # The following statement needs to be changed for different input types.
  # Our input `s` is actually of type `bytes`, so we use `np.frombuffer`.
  # For inputs of type `str`, change `np.frombuffer` to `np.fromstring`
  #  or transform the input into a `bytes` instance.
  arr = np.frombuffer(s, dtype=np.uint8)

  unique_chars, char_counts = np.unique(arr, return_counts=True)

  return dict(zip(unique_chars, char_counts))

For the test input (first 100,000 characters of the complete works of Shakespeare), this method performs better than any other tested here. But note that on a different input, this approach might yield worse performance than the other methods. Pre-sortedness of the input and number of repetitions per element are important factors affecting the performance.

count_chars(s)

=> 2.960809530000006

If you are thinking about using this method because it's over twice as fast as collections.Counter, consider this:

• collections.Counter has linear time complexity. numpy.unique is linear at best, quadratic at worst.

• The speedup is not really that significant - you save ~3.5 milliseconds per iteration on an input of length 100,000.

• Using numpy.unique obviously requires numpy.

That considered, it seems reasonable to use Counter unless you need to be really fast. And in that case, you better know what you're doing or else you'll end up being slower with numpy than without it.

Appendix 2: A somewhat useful plot

I ran the 13 different methods above on prefixes of the complete works of Shakespeare and made an interactive plot. Note that in the plot, both prefixes and durations are displayed in logarithmic scale (the used prefixes are of exponentially increasing length). Click on the items in the legend to show/hide them in the plot.

How about loading it from MemoryStream?

    BitmapImage bitmapImage = new BitmapImage();
    bitmapImage.BeginInit();
    bitmapImage.StreamSource = memory;

    bitmapImage.EndInit();

When it comes to inserting a picture, r2evans's suggestion of ![Caption for the picture.](/path/to/image.png) can be problematic if PDF output is required.

The knitr function include_graphics knitr::include_graphics('/path/to/image.png') is a more portable alternative that will generate, on your behalf, the markdown that is most appropriate to the output format that you are generating.

According to this page.

NOTE: The accepted answer works for associative arrays, but it will not work as expected with indexed arrays (explained below). If you want to compare either of them, then use this solution. Also, this function may not works with multidimensional arrays (due to the nature of array_diff function).

Testing two indexed arrays, which elements are in different order, using $a == $b or $a === $b fails, for example:

<?php
    (array("x","y") == array("y","x")) === false;
?>

That is because the above means:

array(0 => "x", 1 => "y") vs. array(0 => "y", 1 => "x").

To solve that issue, use:

<?php
function array_equal($a, $b) {
    return (
         is_array($a) 
         && is_array($b) 
         && count($a) == count($b) 
         && array_diff($a, $b) === array_diff($b, $a)
    );
}
?>

Comparing array sizes was added (suggested by super_ton) as it may improve speed.

Big task, chances are you shouldn't reinvent the wheel rather using an existing wheel (such as paypal).

However, if you insist on continuing. Start small, you can use a credit card processing facility (Moneris, Authorize.NET) to process credit cards. Most providers have an API you can use. Be wary that you may need to use different providers depending on the card type (Discover, Visa, Amex, Mastercard) and Country (USA, Canada, UK). So build it so that you can communicate with multiple credit card processing APIs.

Security is essential if you are storing credit cards and payment details. Ensure that you are encrypting things properly.

Again, don't reinvent the wheel. You are better off using an existing provider and focussing your development attention on solving an problem that can't easily be purchase.

i'm not sure what "application id" you are referring to, but for a unique identifier of your application you can use:

getApplication().getPackageName() method from your current activity

I don't love relying on storage internals (that datetime is a float with whole number = day and fractional = time), but I do the same thing as the answer Jhonny D. Cano. This is the way all of the db devs I know do it. Definitely do not convert to string. If you must avoid processing as float/int, then the best option is to pull out hour/minute/second/milliseconds with DatePart()

For those who may need this info:

I figured out that you can pretty much run a command that's in your PATH from a PS script, and it should work.

Sometimes you may have to pre-launch this command with cmd.exe /c

Examples

Calling git from a PS script

I had to repackage a git client wrapped in Chocolatey (for those who may not know, it's a kind of app-store for Windows) which massively uses PS scripts.

I found out that, once git is in the PATH, commands like

$ca_bundle = git config --get http.sslCAInfo

will store the location of git crt file in $ca_bundle variable.

Looking for an App

Another example that is a combination of the present SO post and this SO post is the use of where command

$java_exe = cmd.exe /c where java

will store the location of java.exe file in $java_exe variable.

You can use this command

$ git rev-list HEAD

You can also use the head Unix command to show the latest n HEAD commits like

$ git rev-list HEAD | head - 2

It basically is higher/greater in everything else. A keyboard is less of a priority than the real time process. This means the process will be taken into account faster then keyboard and if it can't handle that, then your keyboard is slowed.

This worked for me like a magic.

I logged into database and registered the listener.

alter system set local_listener='(...)';
alter system register;

You can use Css Selector or Xpath:

Approach 1 : CSS Selector

driver.switchTo().frame(driver.findElement(By.cssSelector("iframe[title='Fill Quote']")));

Approach 2 : Xpath

driver.switchTo().frame(driver.findElement(By.xpath("//iframe[@title='Fill Quote']")));

AFAIK, All of the methods currently to capture a screenshot of android use the /dev/graphics/fb0 framebuffer. This includes ddms. It does require root to read from this stream. ddms uses adbd to request the information, so root is not required as adb has the permissions needed to request the data from /dev/graphics/fb0.

The framebuffer contains 2+ "frames" of RGB565 images. If you are able to read the data, you would have to know the screen resolution to know how many bytes are needed to get the image. each pixel is 2 bytes, so if the screen res was 480x800, you would have to read 768,000 bytes for the image, since a 480x800 RGB565 image has 384,000 pixels.

I found this link helpful

$scope.loadSkillTags = function (query) {
var data = {qData: query};
   return SkillService.querySkills(data).then(function(response) {
   return response.data;
  });
 };

Because of the tooltip function, you have to tell angularJS that you are using jQuery.

This is your directive:

myApp.directive('tooltip', function () {
    return {
        restrict: 'A',
        link: function (scope, element, attrs) {
            element.on('mouseenter', function () {
                jQuery.noConflict();
                (function ($) {
                    $(element[0]).tooltip('show');
                })(jQuery);
            });
        }
    };
});

and this is how to use the directive :

<a href="#" title="ToolTip!" data-toggle="tooltip" tooltip></a>

Try:

SELECT result.* 
FROM (
 [QUERY 1]
 UNION
 [QUERY 2]
) result
ORDER BY result.id

Where [QUERY 1] and [QUERY 2] are your two queries that you want to merge.

There's a class of question on SO that sometimes make less than perfect sense, this one is perilously close :-)

Perhaps you could explain your aversion to using one of the two methods you ruled out.

If it's just because you don't want to pepper your code with if statements or exception catching code, one solution is to use a helper function that will take care of it for you, something like:

static String substring_safe (String s, int start, int len) { ... }

which will check lengths beforehand and act accordingly (either return smaller string or pad with spaces).

Then you don't have to worry about it in your code at all, just call:

String s2 = substring_safe (s, 10, 7);

instead of:

String s2 = s.substring (10,7);

This would work in the case that you seem to be worried about (based on your comments to other answers), not breaking the flow of the code when doing lots of string building stuff.

Make it so that your function accepts a const std::string& instead of by-value. Not only does this avoid the copy and is therefore always preferable when accepting strings into functions, but it also enables the compiler to construct a temporary std::string from the char[] that you're giving it. :)

Right click on a photo and open in a new tab/window. Right click on inspect element. Search for:

instagram://media?id=

This will give you:

instagram://media?id=############# /// the ID

The full id construct from

photoID_userID

To get the user id, search for:

instapp:owner_user_id Will be in content=

This worked for me.

header = ['row1', 'row2', 'row3']

    writer.writerow(i for i in header)
    for j in some_list:
        writer.writerow(j)

Solution With Less XAML and More C#

If you define the ListView in XAML:

<ListView x:Name="listView"/>

Then you can add columns and populate it in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Add columns
    var gridView = new GridView();
    this.listView.View = gridView;
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Id", DisplayMemberBinding = new Binding("Id") });
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Name", DisplayMemberBinding = new Binding("Name") });

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

Solution With More XAML and less C#

However, it's easier to define the columns in XAML (inside the ListView definition):

<ListView x:Name="listView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
        </GridView>
    </ListView.View>
</ListView>

And then just populate the list in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

MyItem Definition

MyItem is defined like this:

public class MyItem
{
    public int Id { get; set; }

    public string Name { get; set; }
}

Git can search diffs with the -S option (it's called pickaxe in the docs)

git log -S password

This will find any commit that added or removed the string password. Here a few options:

• -p: will show the diffs. If you provide a file (-p file), it will generate a patch for you.
• -G: looks for differences whose added or removed line matches the given regexp, as opposed to -S, which "looks for differences that introduce or remove an instance of string".
• --all: searches over all branches and tags; alternatively, use --branches[=<pattern>] or --tags[=<pattern>]

evict non ISO-8859-1 characters, will be replace by '?' (before send to a ISO-8859-1 DB by example):

utf8String = new String ( utf8String.getBytes(), "ISO-8859-1" );

We were also facing this issue when using IE version 11 to access our React app (create-react-app with react version 16.0.0 with jQuery v3.1.1) on the enterprise intranet. To solve it, i simply followed the directions at this url which are also listed below:

1. Make sure to set the DOCTYPE to standards mode by making sure the first line of the master file is: <!DOCTYPE html>

2. Force IE 11 to use the latest internal version by including the following meta tag in the head tag: <meta http-equiv="X-UA-Compatible" content="IE=edge;" />

NOTE: I did not face the problem when using IE to access the app in development mode on my local machine (localhost:3000). The problem occurred only when accessing the app deployed to the DEV server on the company Intranet, probably because of some company wide Windows OS policy settings and/or IE Internet Options.

ex: url/:id

var sample= app.controller('sample', function ($scope, $routeParams) {
  $scope.init = function () {
    var qa_id = $routeParams.qa_id;
  }
});

If you're already on EL 3.0 (Java EE 7; WildFly, Tomcat 8, GlassFish 4, etc), then you could use the new += operator for this:

<c:out value="${empty value ? 'none' : value += ' enabled'}" />

If you're however not on EL 3.0 yet, and the value is a genuine java.lang.String instance (and thus not e.g. java.lang.Long), then use EL 2.2 (Java EE 7; JBoss AS 6/7, Tomcat 7, GlassFish 3, etc) capability of invoking direct methods with arguments, which you then apply on String#concat():

<c:out value="${empty value ? 'none' : value.concat(' enabled')}" />

Or if you're even not on EL 2.2 yet, then use JSTL <c:set> to create a new EL variable with the concatenated values just inlined in value:

<c:set var="enabled" value="${value} enabled" />
<c:out value="${empty value ? 'none' : enabled}" />

From the node.js documentation, "To have a module execute code multiple times, export a function, and call that function", you could use node.js module.export and have a single file to manage the db connections.You can find more at Node.js documentation. Let's say db.js file be like:

    const mysql = require('mysql');

    var connection;

    module.exports = {

    dbConnection: function () {

        connection = mysql.createConnection({
            host: "127.0.0.1",
            user: "Your_user",
            password: "Your_password",
            database: 'Your_bd'
        });
        connection.connect();
        return connection;
    }

    };

Then, the file where you are going to use the connection could be like useDb.js:

const dbConnection = require('./db');

var connection;

function callDb() {

    try {

        connection = dbConnectionManager.dbConnection();

        connection.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
            if (!error) {

                let response = "The solution is: " + results[0].solution;
                console.log(response);

            } else {
                console.log(error);
            }
        });
        connection.end();


    } catch (err) {
        console.log(err);
    }
}

There is an event Page.Unload. At that moment page is already rendered in HTML and HTML can't be modified. Still, all page objects are available.

String s="hi dude i                                 want apple";
    s = s.replaceAll("\\s+"," ");
    String[] split = s.split(" ");
    s="";
    for (int i = 0; i < split.length; i++) {
        split[i]=Character.toUpperCase(split[i].charAt(0))+split[i].substring(1);
        s+=split[i]+" ";
        System.out.println(split[i]);
    }
    System.out.println(s);

MarkerImage has been deprecated for Icon

Until version 3.10 of the Google Maps JavaScript API, complex icons were defined as MarkerImage objects. The Icon object literal was added in 3.10, and replaces MarkerImage from version 3.11 onwards. Icon object literals support the same parameters as MarkerImage, allowing you to easily convert a MarkerImage to an Icon by removing the constructor, wrapping the previous parameters in {}'s, and adding the names of each parameter.

Phillippe's code would now be:

 var icon = {
     url: "../res/sit_marron.png", // url
     scaledSize: new google.maps.Size(width, height), // size
     origin: new google.maps.Point(0,0), // origin
     anchor: new google.maps.Point(anchor_left, anchor_top) // anchor 
 };

 position = new google.maps.LatLng(latitud,longitud)
 marker = new google.maps.Marker({
  position: position,
  map: map,
  icon: icon
 });

If the other side is empty. I guess the simplest way would be to add an empty view (e.g. a linear layout) then set both views' widths to fill_parent and both their weights to 1.

This works in a LinearLayout...

The function returns a FileStream object. So you could use it's return value to open your StreamWriter or close it using the proper method of the object:

File.Create(myPath).Close();

Try StickyList from Cactoos:

List<String> list = new StickyList<>(iterable);

Disclaimer: I'm one of the developers.

I think you (meant)want an list with the first 30 cells already filled. So

   f = []

   for i in range(30):
       f.append(0)

An example to where this could be used is in Fibonacci sequence. See problem 2 in Project Euler

Aside from suggesting you read the docs for retrieve() carefully (http://docs.python.org/library/urllib.html#urllib.URLopener.retrieve), I would suggest actually calling read() on the content of the response, and then saving it into a file of your choosing rather than leaving it in the temporary file that retrieve creates.

In my case the file is a shell script (*.sh file) meant to deploy our project to a local development server, for my developers.

The shell script should work consistently and may be updated; so I tracked it in the same Git project as the code which the script is meant to deploy.

The shell script runs one executable, and then allows that executable to run; so the script is still running; so my shell still has the script open; so it's locked.

I Ctrl+C'd to kill the script (so now my local dev server is no longer accessible), now I can checkout freely.

Here is the simplest solution using javascript string functions.

  substr(COOKIE_NAME.length);

There is no way to get the memory address of a value in Python 2.7 in general. In Jython or PyPy, the implementation doesn't even know your value's address (and there's not even a guarantee that it will stay in the same place—e.g., the garbage collector is allowed to move it around if it wants).

However, if you only care about CPython, id is already returning the address. If the only issue is how to format that integer in a certain way… it's the same as formatting any integer:

>>> hex(33)
0x21
>>> '{:#010x}'.format(33) # 32-bit
0x00000021
>>> '{:#018x}'.format(33) # 64-bit
0x0000000000000021

… and so on.

However, there's almost never a good reason for this. If you actually need the address of an object, it's presumably to pass it to ctypes or similar, in which case you should use ctypes.addressof or similar.

pygolang provides sync.WorkGroup which, in particular, propagates exception from spawned worker threads to the main thread. For example:

#!/usr/bin/env python
"""This program demostrates how with sync.WorkGroup an exception raised in
spawned thread is propagated into main thread which spawned the worker."""

from __future__ import print_function
from golang import sync, context

def T1(ctx, *argv):
    print('T1: run ... %r' % (argv,))
    raise RuntimeError('T1: problem')

def T2(ctx):
    print('T2: ran ok')

def main():
    wg = sync.WorkGroup(context.background())
    wg.go(T1, [1,2,3])
    wg.go(T2)

    try:
        wg.wait()
    except Exception as e:
        print('Tmain: caught exception: %r\n' %e)
        # reraising to see full traceback
        raise

if __name__ == '__main__':
    main()

gives the following when run:

T1: run ... ([1, 2, 3],)
T2: ran ok
Tmain: caught exception: RuntimeError('T1: problem',)

Use the class URLEncoder:

URLEncoder.encode(String s, String enc)

Where :

s - String to be translated.

enc - The name of a supported character encoding.

Standard charsets:

US-ASCII Seven-bit ASCII, a.k.a. ISO646-US, a.k.a. the Basic Latin block of the Unicode character set ISO-8859-1 ISO Latin Alphabet No. 1, a.k.a. ISO-LATIN-1

UTF-8 Eight-bit UCS Transformation Format

UTF-16BE Sixteen-bit UCS Transformation Format, big-endian byte order

UTF-16LE Sixteen-bit UCS Transformation Format, little-endian byte order

UTF-16 Sixteen-bit UCS Transformation Format, byte order identified by an optional byte-order mark

Example:

import java.net.URLEncoder;

String stringEncoded = URLEncoder.encode(
    "This text must be encoded! aeiou áéíóú ñ, peace!", "UTF-8");

Awk can fix up the output to give just what the questioner asked for. On my Solaris 10 system, find -ls prints size in KB as the second field, so:

% find . -name '*.ear' -ls | awk '{print $2, $11}'
5400 ./dir1/dir2/earFile2.ear
5400 ./dir1/dir2/earFile3.ear
5400 ./dir1/dir2/earFile1.ear

Otherwise, use -exec ls -lh and pick out the size field from the output. Again on Solaris 10:

% find . -name '*.ear' -exec ls -lh {} \; | awk '{print $5, $9}'
5.3M ./dir1/dir2/earFile2.ear
5.3M ./dir1/dir2/earFile3.ear
5.3M ./dir1/dir2/earFile1.ear

atan2(y,x) is generally used if you want to convert cartesian coordinates to polar coordinates. It will give you the angle, while sqrt(x*x+y*y) or, if available, hypot(y,x) will give you the size.

atan(x) is simply the inverse of tan. In the annoying case you have to use atan(y/x) because your system doesn't provide atan2, you would have to do additional checks for the signs of x and y, and for x=0, in order to get the correct angle.

Note: atan2(y,x) is defined for all real values of y and x, except for the case when both arguments are zero.

function trimRegex(str, regex){

You can get this done using html string and setting the html to Textview using
txtView.setText(Html.fromHtml("Your html string here"));

For example :

txtView.setText(Html.fromHtml("<html><body><font size=5 color=red>Hello </font> World </body><html>"));`

There're at least four different ways doing this conversion.

1. Encoding's GetString
   , but you won't be able to get the original bytes back if those bytes have non-ASCII characters.

2. BitConverter.ToString
   The output is a "-" delimited string, but there's no .NET built-in method to convert the string back to byte array.

3. Convert.ToBase64String
   You can easily convert the output string back to byte array by using Convert.FromBase64String.
   Note: The output string could contain '+', '/' and '='. If you want to use the string in a URL, you need to explicitly encode it.

4. HttpServerUtility.UrlTokenEncode
   You can easily convert the output string back to byte array by using HttpServerUtility.UrlTokenDecode. The output string is already URL friendly! The downside is it needs System.Web assembly if your project is not a web project.

A full example:

byte[] bytes = { 130, 200, 234, 23 }; // A byte array contains non-ASCII (or non-readable) characters

string s1 = Encoding.UTF8.GetString(bytes); // ???
byte[] decBytes1 = Encoding.UTF8.GetBytes(s1);  // decBytes1.Length == 10 !!
// decBytes1 not same as bytes
// Using UTF-8 or other Encoding object will get similar results

string s2 = BitConverter.ToString(bytes);   // 82-C8-EA-17
String[] tempAry = s2.Split('-');
byte[] decBytes2 = new byte[tempAry.Length];
for (int i = 0; i < tempAry.Length; i++)
    decBytes2[i] = Convert.ToByte(tempAry[i], 16);
// decBytes2 same as bytes

string s3 = Convert.ToBase64String(bytes);  // gsjqFw==
byte[] decByte3 = Convert.FromBase64String(s3);
// decByte3 same as bytes

string s4 = HttpServerUtility.UrlTokenEncode(bytes);    // gsjqFw2
byte[] decBytes4 = HttpServerUtility.UrlTokenDecode(s4);
// decBytes4 same as bytes

Writeup with pictures about installing SQL Server

How to select a local server:

When you are asked to connect to a 'database server' right when you open up SQL Server Management Studio do this:

1) Make sure you have Server Type: Database

2) Make sure you have Authentication: Windows Authentication (no username & password)

3) For the server name field look to the right and select the drop down arrow, click 'browse for more'

4) New window pops up 'Browse for Servers', make sure to pick 'Local Servers' tab and under 'Database Engine' you will have the local server you set up during installation of SQL Server 14

How do I create a local database inside of Microsoft SQL Server 2014?

1) After you have connected to a server, bring up the Object Explorer toolbar under 'View' (Should open by default)

2) Now simply right click on 'Databases' and then 'Create new Database' to be taken through the database creation tools!

To complement the existing helpful answers:

Using Bash's own regex-matching operator, =~, is a faster alternative in this case, given that you're only matching a single value already stored in a variable:

set -- '12-34-5678' # set $1 to sample value

kREGEX_DATE='^[0-9]{2}[-/][0-9]{2}[-/][0-9]{4}$' # note use of [0-9] to avoid \d
[[ $1 =~ $kREGEX_DATE ]]
echo $? # 0 with the sample value, i.e., a successful match

Note, however, that the caveat re using flavor-specific regex constructs such as \d equally applies: While =~ supports EREs (extended regular expressions), it also supports the host platform's specific extension - it's a rare case of Bash's behavior being platform-dependent.

To remain portable (in the context of Bash), stick to the POSIX ERE specification.

Note that =~ even allows you to define capture groups (parenthesized subexpressions) whose matches you can later access through Bash's special ${BASH_REMATCH[@]} array variable.

Further notes:

• $kREGEX_DATE is used unquoted, which is necessary for the regex to be recognized as such (quoted parts would be treated as literals).

• While not always necessary, it is advisable to store the regex in a variable first, because Bash has trouble with regex literals containing \.

  • E.g., on Linux, where \< is supported to match word boundaries, [[ 3 =~ \<3 ]] && echo yes doesn't work, but re='\<3'; [[ 3 =~ $re ]] && echo yes does.

• I've changed variable name REGEX_DATE to kREGEX_DATE (k signaling a (conceptual) constant), so as to ensure that the name isn't an all-uppercase name, because all-uppercase variable names should be avoided to prevent conflicts with special environment and shell variables.

I'm using .Net Core 2 mvc, this one work for me ( to get the previews page) :

Try browse the WCF in IIS see if it's alive and works normally,

In my case it's because the physical path of the WCF is misdirected.

If you're using C++11 or above, I'd suggest using std::snprintf over std::strcpy or std::strncpy because of its safety (i.e., you determine how many characters can be written to your buffer) and because it null-terminates the string for you (so you don't have to worry about it). It would be like this:

#include <string>
#include <cstdio>

std::string tmp = "cat";
char tab2[1024];
std::snprintf(tab2, sizeof(tab2), "%s", tmp.c_str());

In C++17, you have this alternative:

#include <string>
#include <cstdio>
#include <iterator>

std::string tmp = "cat";
char tab2[1024];
std::snprintf(tab2, std::size(tab2), "%s", tmp.c_str());

  //best and simple way to show keys and values

    //initialize map
    Map<Integer, String> map = new HashMap<Integer, String>();

   //Add some values
    map.put(1, "Hi");
    map.put(2, "Hello");

    // iterate map using entryset in for loop

Yes this is possible, however not convenient as Jens said. Using Next generation load balancers like Alteon, which Uses a proprietary protocol called DSSP(Distributed site state Protocol) which performs regular site checks to make sure that the service is available both Locally or Globally i.e different geographical areas. You need to however in your Master DNS to delegate the URL or Service to the device by configuring it as an Authoritative Name Server for that IP or Service. By doing this, the device answers DNS queries where it will resolve the IP that has a service by Round-Robin or is not congested according to how you have chosen from several metrics.

import subprocess
p = sub.Popen('file yourfile.txt', stdout=sub.PIPE, stderr=sub.PIPE)
output, errors = p.communicate()
print(output)

As Steven pointed out, subprocess is the way. You can get the command output by the way above as this post said

System.Windows.Forms.Clipboard.SetText (Windows Forms) or System.Windows.Clipboard.SetText (WPF)

Here's my story. Under 'Actions' on the AVD manager, I viewed the details for the AVD which wasn't working. Scrolling down, I found the line:

image.sysdir.1: add-ons\addon-google_apis-google-16\images\armeabi-v7a\

I then navigated to this file at:

C:\Users\XXXX\AppData\Local\Android\sdk\add-ons\addon-google_apis-google-16\images\armeabi-v7a

I found there was no kernel file. However, I did find a kernel file at:

C:\Users\XXXX\AppData\Local\Android\sdk\system-images\android-16\default\armeabi-v7a

So I copied it and pasted back into:

C:\Users\XXXX\AppData\Local\Android\sdk\add-ons\addon-google_apis-google-16\images\armeabi-v7a

The AVD then worked.

Including "string.h" makes things easier. An easier way to tackle your problem is:

#include <string.h>
    char* createStr(){
    static char str[20] = "my";
    return str;
}
int main(){
    char a[20];
    strcpy(a,createStr()); //this will copy the returned value of createStr() into a[]
    printf("%s",a);
    return 0;
}

How unchecking radio does (not) work

You cannot easily implement uncheck trivially via if(this.checked) this.checked = false, (if you really want to, see the hacker way at the end) because the events fire in this order:

1. mousedown or keydown
2. mouseup or keyup
3. if not checked, set the checked property now
4. click
5. input (only if state is changed)
6. change (only if state is changed)

Now in which event to perform the mentioned uncheck?

• mouseup or mousedown: then the step 3 the value is set back to true and change and input event doesn't even fire as the state didn't change when they are called in the sequence - so you can't uncheck it here
• click: then the state is always false and input and change also doesn't fire - so you can't check it
• input or change: it doesn't fire when the state is not changed and clicking selected element doesn't change the state - so you can't do anything useful here

The naive way

As you can learn from the sequence above, the way is:

1. read the previous state in mouseup
2. set the state in click as negation of previous state

If you want to store the previous state in data attribute, keep in mind that it is saved as string, whereas the checked attribute is boolean. So you can implement it like:

radio.onmouseup = function() { this.dataset.checked = this.checked? 1 : ""; }
radio.onclick = function() { this.checked = !this.dataset.checked; }

It seemingly works, but you should not do this for these reasons:

• the user may mousedown somewhere else, then hover above radio button, then mouseup: in this case mouseup fires and click does not
• the user may use Tab to focus radio group, then arrows to change: mouseup doesn't fire and click does

The proper way

There is another issue: dynamically added radio buttons. There are two ways:

1. element.appendChild(radio) - if you enable deselect on all radios in DOMContentLoaded event, this dynamically added radio is not affected
2. element.innerHTML+= '<input type="radio">' - effectively replaces the HTML contents of the element and re-creates DOM inside it - so all event listeners are discarded

To solve (2), I recommend onclick content attribute. Note that element.onclick = fn and element.setAttribute("onclick", "fn()") are two different things. Also note that onclick fires everytime the user activates the radio, regardless of the interface he used.

Yet another issue: if you enable deselect, then you should also enable switching by Space to mimic checkboxes behaviour. The following code solves all mentioned issues:

function deselectableRadios(rootElement) {
  if(!rootElement) rootElement = document;
  if(!window.radioChecked) window.radioChecked = null;
  window.radioClick = function(e) {
    const obj = e.target;
    if(e.keyCode) return obj.checked = e.keyCode!=32;
    obj.checked = window.radioChecked != obj;
    window.radioChecked = obj.checked ? obj : null;
  }
  rootElement.querySelectorAll("input[type='radio']").forEach( radio => {
    radio.setAttribute("onclick", "radioClick(event)");
    radio.setAttribute("onkeyup", "radioClick(event)");
  });
}

deselectableRadios();

<label><input type="radio" name="tag1">one</label>
<label><input type="radio" name="tag1">two</label>
<label><input type="radio" name="tag1">three</label>
<label><input type="radio" name="tag1">four</label>

Now you can call deselectableRadios() anytime you dynamically add content and calling it on radios multiple times doesn't break it. You can also specify the rootElement to update only a subtree of HTML DOM and make your web faster. If you don't like the global state, you can use the hacker way:

The hacker way

The point is to abuse setTimeout on mouseup to call it after the checked property is set:

function deselectable() {
  setTimeout(checked => this.checked = !checked, 0, this.checked);
}

Now you can make any radio button deselectable:

radio.onmouseup = deselectable;

But this simple one-liner works just with clicking and doesn't solve the issues mentioned above.

The modern way

Deselectable radio is basically checkbox where only one in the group can be checked. If your browser supports the appearance CSS4 feature, you can simply

<input type="checkbox" name="foo" style="appearance: radio">

and then in onclick event getElementsByName("foo") and uncheck all remaining checkboxes of the name (checkboxes doesn't send value if they are not checked).

You can use getnameinfo for Windows and for Linux.

Assuming you have a good (i.e. it's members have appropriate values) sockaddr* called pSockaddr:

char clienthost[NI_MAXHOST];  //The clienthost will hold the IP address.
char clientservice[NI_MAXSERV];
int theErrorCode = getnameinfo(pSockaddr, sizeof(*pSockaddr), clienthost, sizeof(clienthost), clientservice, sizeof(clientservice), NI_NUMERICHOST|NI_NUMERICSERV);

if( theErrorCode != 0 )
{
    //There was an error.
    cout << gai_strerror(e1) << endl;
}else{
    //Print the info.
    cout << "The ip address is = " << clienthost << endl;
    cout << "The clientservice = " << clientservice << endl;
}

I had this problem with bundles having incorrect path's to images and CssRewriteUrlTransform not resolving relative parent paths .. correctly (there was also problem with external resources like webfonts). That's why I wrote this custom transform (appears to do all of the above correctly):

public class CssRewriteUrlTransform2 : IItemTransform
{
    public string Process(string includedVirtualPath, string input)
    {
        var pathParts = includedVirtualPath.Replace("~/", "/").Split('/');
        pathParts = pathParts.Take(pathParts.Count() - 1).ToArray();
        return Regex.Replace
        (
            input,
            @"(url\(['""]?)((?:\/??\.\.)*)(.*?)(['""]?\))",
            m => 
            {
                // Somehow assigning this to a variable is faster than directly returning the output
                var output =
                (
                    // Check if it's an aboslute url or base64
                    m.Groups[3].Value.IndexOf(':') == -1 ?
                    (
                        m.Groups[1].Value +
                        (
                            (
                                (
                                    m.Groups[2].Value.Length > 0 ||
                                    !m.Groups[3].Value.StartsWith('/')
                                )
                            ) ?
                            string.Join("/", pathParts.Take(pathParts.Count() - m.Groups[2].Value.Count(".."))) :
                            ""
                        ) +
                        (!m.Groups[3].Value.StartsWith('/') ? "/" + m.Groups[3].Value : m.Groups[3].Value) +
                        m.Groups[4].Value
                    ) :
                    m.Groups[0].Value
                );
                return output;
            }
        );
    }
}

Edit: I didn't realize it, but I used some custom extension methods in the code. The source code of those is:

/// <summary>
/// Based on: http://stackoverflow.com/a/11773674
/// </summary>
public static int Count(this string source, string substring)
{
    int count = 0, n = 0;

    while ((n = source.IndexOf(substring, n, StringComparison.InvariantCulture)) != -1)
    {
        n += substring.Length;
        ++count;
    }
    return count;
}

public static bool StartsWith(this string source, char value)
{
    if (source.Length == 0)
    {
        return false;
    }
    return source[0] == value;
}

Of course it should be possible to replace String.StartsWith(char) with String.StartsWith(string).

If you are not using programming then do the following (1) select the column (2) right click and select Format Cells (3) Select "Custom" (4) Just Under "Type:" type dd/mm/yyyy hh:mm:ss

$("#mydropdownlist").val("thevalue");

just make sure the value in the options tags matches the value in the val method.

I built one of the first SOAP servers, including code generation and WSDL generation, from the original spec as it was being developed, when I was working at Hewlett-Packard. I do NOT recommend using SOAP for anything.

The acronym "SOAP" is a lie. It is not Simple, it is not Object-oriented, it defines no Access rules. It is, arguably, a Protocol. It is Don Box's worst spec ever, and that's quite a feat, as he's the man who perpetrated "COM".

There is nothing useful in SOAP that can't be done with REST for transport, and JSON, XML, or even plain text for data representation. For transport security, you can use https. For authentication, basic auth. For sessions, there's cookies. The REST version will be simpler, clearer, run faster, and use less bandwidth.

XML-RPC clearly defines the request, response, and error protocols, and there are good libraries for most languages. However, XML is heavier than you need for many tasks.

Query_string

(Following is the text of the linked section of the Wikipedia entry.)

Structure

A typical URL containing a query string is as follows:

http://server/path/program?query_string

When a server receives a request for such a page, it runs a program (if configured to do so), passing the query_string unchanged to the program. The question mark is used as a separator and is not part of the query string.

A link in a web page may have a URL that contains a query string, however, HTML defines three ways a web browser can generate the query string:

• a web form via the ... element
• a server-side image map via the ?ismap? attribute on the element with a construction
• an indexed search via the now deprecated element

Web forms

The main use of query strings is to contain the content of an HTML form, also known as web form. In particular, when a form containing the fields field1, field2, field3 is submitted, the content of the fields is encoded as a query string as follows:

field1=value1&field2=value2&field3=value3...

• The query string is composed of a series of field-value pairs.
• Within each pair, the field name and value are separated by an equals sign. The equals sign may be omitted if the value is an empty string.
• The series of pairs is separated by the ampersand, '&' (or semicolon, ';' for URLs embedded in HTML and not generated by a ...; see below). While there is no definitive standard, most web frameworks allow multiple values to be associated with a single field:

field1=value1&field1=value2&field1=value3...

For each field of the form, the query string contains a pair field=value. Web forms may include fields that are not visible to the user; these fields are included in the query string when the form is submitted

This convention is a W3C recommendation. W3C recommends that all web servers support semicolon separators in addition to ampersand separators[6] to allow application/x-www-form-urlencoded query strings in URLs within HTML documents without having to entity escape ampersands.

Technically, the form content is only encoded as a query string when the form submission method is GET. The same encoding is used by default when the submission method is POST, but the result is not sent as a query string, that is, is not added to the action URL of the form. Rather, the string is sent as the body of the HTTP request.

List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("param1","value1");

String query = URLEncodedUtils.format(params, "utf-8");

URI url = URIUtils.createURI(scheme, userInfo, authority, port, path, query, fragment); //can be null
HttpGet httpGet = new HttpGet(url);

URI javadoc

Note: url = new URI(...) is buggy

Process is to clean up and then reinstall with the following commands:

rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install )"

Notes:

• Always check curl | bash (or ruby) commands before running them
• http://brew.sh/ (for installation notes)
• https://raw.githubusercontent.com/Homebrew/install/master/install (for clean up notes, see "Homebrew is already installed")

is null is the syntax I use for such things, when COALESCE is of no help.

Try:

if (@zipCode is null)
  begin
    ([Portal].[dbo].[Address].Position.Filter(@radiusBuff) = 1)   
  end
else 
  begin
    ([Portal].[dbo].[Address].PostalCode=@zipCode )
  end  

In Bootstrap 4, use:

<div class="d-flex justify-content-center">...</div>

You can also change the position depending on what you want:

<div class="d-flex justify-content-start">...</div>
<div class="d-flex justify-content-end">...</div>
<div class="d-flex justify-content-between">...</div>
<div class="d-flex justify-content-around">...</div>

Reference here

This worked for me in Firefox and Chrome and IE8...

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

    </head>

            <div class="layer">Lorem Ipsum</div>
        </div>
    </body>
</html>

... you may want to test this with IE6 as well (I'm not sure if it'll work there).

Mysql error "28 from storage engine" - means "not enough disk space".

Very simple, no library required:

var date = new Date();
var firstDay = new Date(date.getFullYear(), date.getMonth(), 1);
var lastDay = new Date(date.getFullYear(), date.getMonth() + 1, 0);

or you might prefer:

var date = new Date(), y = date.getFullYear(), m = date.getMonth();
var firstDay = new Date(y, m, 1);
var lastDay = new Date(y, m + 1, 0);

EDIT

Some browsers will treat two digit years as being in the 20th century, so that:

new Date(14, 0, 1);

gives 1 January, 1914. To avoid that, create a Date then set its values using setFullYear:

var date = new Date();
date.setFullYear(14, 0, 1); // 1 January, 14

I think every process you make start executing the line you create so something like this...

pid=fork() at line 6. fork function returns 2 values 
you have 2 pids, first pid=0 for child and pid>0 for parent 
so you can use if to separate

.

/*
    sleep(int time) to see clearly
    <0 fail 
    =0 child
    >0 parent
*/
int main(int argc, char** argv) {
    pid_t childpid1, childpid2;
    printf("pid = process identification\n");
    printf("ppid = parent process identification\n");
    childpid1 = fork();
    if (childpid1 == -1) {
        printf("Fork error !\n");
    }
    if (childpid1 == 0) {
        sleep(1);
        printf("child[1] --> pid = %d and  ppid = %d\n",
                getpid(), getppid());
    } else {
        childpid2 = fork();
        if (childpid2 == 0) {
            sleep(2);
            printf("child[2] --> pid = %d and ppid = %d\n",
                    getpid(), getppid());
        } else {
            sleep(3);
            printf("parent --> pid = %d\n", getpid());
        }
    }
    return 0;
}

//pid = process identification
//ppid = parent process identification
//child[1] --> pid = 2399 and  ppid = 2398
//child[2] --> pid = 2400 and ppid = 2398
//parent --> pid = 2398

I had the same problem and got it fixed by deleting an extra library.

To do try this solution go to File > Project Structure (on a mac you can use the command "Apple ;")

Then select app on the left tab. Go to the dependencies tab and delete the extra library.

you can wrap -Andrie answer into a generic function

mbind<-function(...){
 Reduce( function(x,y){cbind(x,y[match(row.names(x),row.names(y)),])}, list(...) )
}

Here, you can bind multiple frames with rownames as key

$('.ui-icon-circle-triangle-w').text('<<');

After lot of researching and looking into different solutions proposed here at StackOverflow. I finally decided to write my own solution. My purpose is to have no-throw mechanism because I don't want to crash if the API is unable to fetch the folder size. This method is not suitable for mult-threaded scenario.

First of all I want to check for valid directories while traversing down the file system tree.

private static boolean isValidDir(File dir){
    if (dir != null && dir.exists() && dir.isDirectory()){
        return true;
    }else{
        return false;
    }
}

Second I do not want my recursive call to go into symlinks (softlinks) and include the size in total aggregate.

public static boolean isSymlink(File file) throws IOException {
    File canon;
    if (file.getParent() == null) {
        canon = file;
    } else {
        canon = new File(file.getParentFile().getCanonicalFile(),
                file.getName());
    }
    return !canon.getCanonicalFile().equals(canon.getAbsoluteFile());
}

Finally my recursion based implementation to fetch the size of the specified directory. Notice the null check for dir.listFiles(). According to javadoc there is a possibility that this method can return null.

public static long getDirSize(File dir){
    if (!isValidDir(dir))
        return 0L;
    File[] files = dir.listFiles();
    //Guard for null pointer exception on files
    if (files == null){
        return 0L;
    }else{
        long size = 0L;
        for(File file : files){
            if (file.isFile()){
                size += file.length();
            }else{
                try{
                    if (!isSymlink(file)) size += getDirSize(file);
                }catch (IOException ioe){
                    //digest exception
                }
            }
        }
        return size;
    }
}

Some cream on the cake, the API to get the size of the list Files (might be all of files and folder under root).

public static long getDirSize(List<File> files){
    long size = 0L;
    for(File file : files){
        if (file.isDirectory()){
            size += getDirSize(file);
        } else {
            size += file.length();
        }
    }
    return size;
}

I was able to do that by using \n in the line parameter.

It is specially useful if the file can be validated, and adding a single line generates an invalid file.

In my case, I was adding AuthorizedKeysCommand and AuthorizedKeysCommandUser to sshd_config, with the following command:

- lineinfile: dest=/etc/ssh/sshd_config line='AuthorizedKeysCommand /etc/ssh/ldap-keys\nAuthorizedKeysCommandUser nobody' validate='/usr/sbin/sshd -T -f %s'

Adding only one of the options generates a file that fails validation.

first, it's easy to convert a Date to an Instant

Instant timestamp = new Date().toInstant(); 

Then, you can convert the Instant to any date api in jdk 8 using ofInstant() method:

LocalDateTime date = LocalDateTime.ofInstant(timestamp, ZoneId.systemDefault()); 

Following code will:

• print enabled protocols
• print available protocols
• enable TLS1.2 if platform supports it and if it is not enabled to begin with
• disable SSL3 if it is enabled
• print end result

Constants:

• 48 is SSL3
• 192 is TLS1
• 768 is TLS1.1
• 3072 is TLS1.2

Other protocols will not be affected. This makes this compatible with future protocols (Tls1.3, etc).

Code

// print initial status
    Console.WriteLine("Runtime: " + System.Diagnostics.FileVersionInfo.GetVersionInfo(typeof(int).Assembly.Location).ProductVersion);
    Console.WriteLine("Enabled protocols:   " + ServicePointManager.SecurityProtocol);
    Console.WriteLine("Available protocols: ");
    Boolean platformSupportsTls12 = false;
    foreach (SecurityProtocolType protocol in Enum.GetValues(typeof(SecurityProtocolType))) {                
        Console.WriteLine(protocol.GetHashCode());
        if (protocol.GetHashCode() == 3072){
            platformSupportsTls12 = true;
        }
    }
    Console.WriteLine("Is Tls12 enabled: " + ServicePointManager.SecurityProtocol.HasFlag((SecurityProtocolType)3072));    


// enable Tls12, if possible
    if (!ServicePointManager.SecurityProtocol.HasFlag((SecurityProtocolType)3072)){
        if (platformSupportsTls12){
            Console.WriteLine("Platform supports Tls12, but it is not enabled. Enabling it now.");
            ServicePointManager.SecurityProtocol |= (SecurityProtocolType)3072;
        } else {
            Console.WriteLine("Platform does not supports Tls12.");
        }
    }

// disable ssl3
   if (ServicePointManager.SecurityProtocol.HasFlag(SecurityProtocolType.Ssl3)) { 
      Console.WriteLine("Ssl3SSL3 is enabled. Disabling it now.");
      // disable SSL3. Has no negative impact if SSL3 is already disabled. The enclosing "if" if just for illustration.
      System.Net.ServicePointManager.SecurityProtocol &= ~SecurityProtocolType.Ssl3;                      
   }
    Console.WriteLine("Enabled protocols:   " + ServicePointManager.SecurityProtocol);

Output

Runtime: 4.7.2114.0
Enabled protocols:   Ssl3, Tls
Available protocols: 
0
48
192
768
3072

Platform supports Tls12, but it is not enabled. Enabling it now.
Ssl3 is enabled. Disabling it now.
Enabled protocols:   Tls, Tls12

That's a specific case of the rule that you shouldn't catch any exception you don't know how to handle. If you don't know how to handle it, it's always better to let some other part of the system catch and handle it.

Clarification (thanks @vgm64): if you're already in Terminal, this lets you quickly change to the topmost Finder window without leaving Terminal. This way, you can avoid using the mouse.

I've added the following to my .bash_profile so I can type cdff in Terminal at any time.

function ff { osascript -e 'tell application "Finder"'\
 -e "if (${1-1} <= (count Finder windows)) then"\
 -e "get POSIX path of (target of window ${1-1} as alias)"\
 -e 'else' -e 'get POSIX path of (desktop as alias)'\
 -e 'end if' -e 'end tell'; };\

function cdff { cd "`ff $@`"; };

This is from this macosxhints.com Terminal hint.

Use restart: always in your docker compose file.

Docker-compose up -d will launch container from images again. Use docker-compose start to start the stopped containers, it never launches new containers from images.

nginx:   
    restart: always   
    image: nginx   
    ports:
      - "80:80"
      - "443:443"   links:
      - other_container:other_container

Also you can write the code up in the docker file so that it gets created first, if it has the dependency of other containers.

While checking null or Empty value for a column in my project, I noticed that there are some support concern in various Databases.

Every Database doesn't support TRIM method.

Below is the matrix just to understand the supported methods by different databases.

The TRIM function in SQL is used to remove specified prefix or suffix from a string. The most common pattern being removed is white spaces. This function is called differently in different databases:

• MySQL: TRIM(), RTRIM(), LTRIM()
• Oracle: RTRIM(), LTRIM()
• SQL Server: RTRIM(), LTRIM()

How to Check Empty/Null :-

Below are two different ways according to different Databases-

The syntax for these trim functions are:

1. Use of Trim to check-

   SELECT FirstName FROM UserDetails WHERE TRIM(LastName) IS NULL

2. Use of LTRIM & RTRIM to check-

   SELECT FirstName FROM UserDetails WHERE LTRIM(RTRIM(LastName)) IS NULL

Above both ways provide same result just use based on your DataBase support. It Just returns the FirstName from UserDetails table if it has an empty LastName

Hoping this will help you :)

Database licences are not cheep and are often charged per CPU, therefore by separating out your web-servers you can reduce the cost of your database licences.

E.g if you have 1 server doing both web and database that contains 8 CPUs you will have to pay for an 8 cpu licence. However if you have two servers each with 4 CPUs and runs the database on one server you will only have to pay for a 4 cpu licences

It must be noted that there is also a considerable interest in Wicket and Scala. Wicket fits Scala suprisingly well. If you want to take advantage of the very mature Wicket project and its ecosystem (extensions) plus the concise syntax and productivity advantage of Scala, this one may be for you!

namespace YourProject.Extensions
{
    public static class ListExtensions
    {
        public static bool SetwiseEquivalentTo<T>(this List<T> list, List<T> other)
            where T: IEquatable<T>
        {
            if (list.Except(other).Any())
                return false;
            if (other.Except(list).Any())
                return false;
            return true;
        }
    }
}

Sometimes you only need to know if two lists are different, and not what those differences are. In that case, consider adding this extension method to your project. Note that your listed objects should implement IEquatable!

Usage:

public sealed class Car : IEquatable<Car>
{
    public Price Price { get; }
    public List<Component> Components { get; }

    ...
    public override bool Equals(object obj)
        => obj is Car other && Equals(other);

    public bool Equals(Car other)
        => Price == other.Price
            && Components.SetwiseEquivalentTo(other.Components);

    public override int GetHashCode()
        => Components.Aggregate(
            Price.GetHashCode(),
            (code, next) => code ^ next.GetHashCode()); // Bitwise XOR
}

Whatever the Component class is, the methods shown here for Car should be implemented almost identically.

It's very important to note how we've written GetHashCode. In order to properly implement IEquatable, Equals and GetHashCode must operate on the instance's properties in a logically compatible way.

Two lists with the same contents are still different objects, and will produce different hash codes. Since we want these two lists to be treated as equal, we must let GetHashCode produce the same value for each of them. We can accomplish this by delegating the hashcode to every element in the list, and using the standard bitwise XOR to combine them all. XOR is order-agnostic, so it doesn't matter if the lists are sorted differently. It only matters that they contain nothing but equivalent members.

Note: the strange name is to imply the fact that the method does not consider the order of the elements in the list. If you do care about the order of the elements in the list, this method is not for you!

How things change in a year. In addition to the header attribute in place of xhr.setRequestHeader, current jQuery (1.7.2+) includes a username and password attribute with the $.ajax call.

$.ajax
({
  type: "GET",
  url: "index1.php",
  dataType: 'json',
  username: username,
  password: password,
  data: '{ "comment" }',
  success: function (){
    alert('Thanks for your comment!'); 
  }
});

EDIT from comments and other answers: To be clear - in order to preemptively send authentication without a 401 Unauthorized response, instead of setRequestHeader (pre -1.7) use 'headers':

$.ajax
({
  type: "GET",
  url: "index1.php",
  dataType: 'json',
  headers: {
    "Authorization": "Basic " + btoa(USERNAME + ":" + PASSWORD)
  },
  data: '{ "comment" }',
  success: function (){
    alert('Thanks for your comment!'); 
  }
});

UIImage *image = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://farm4.static.flickr.com/3092/2915896504_a88b69c9de.jpg"]]];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; 


//set contentMode to scale aspect to fit
imageView.contentMode = UIViewContentModeScaleAspectFit;

//change width of frame
//CGRect frame = imageView.frame;
//frame.size.width = 100;
//imageView.frame = frame;

//original lines that deal with frame commented out, yo.
imageView.frame = CGRectMake(10, 20, 60, 60);

...

//Add image view
[myView addSubview:imageView]; 

The original code posted at the top worked well for me in iOS 4.2.

I found that creating a CGRect and specifying all the top, left, width, and height values was the easiest way to adjust the position in my case, which was using a UIImageView inside a table cell. (Still need to add code to release objects)

As an alternative:

listView.setSelector(android.R.color.transparent);

or

listView.setSelector(new StateListDrawable());

Use this code where str is your JSON string:

NSError *err = nil;
NSArray *arr = 
 [NSJSONSerialization JSONObjectWithData:[str dataUsingEncoding:NSUTF8StringEncoding] 
                                 options:NSJSONReadingMutableContainers 
                                   error:&err];
// access the dictionaries
NSMutableDictionary *dict = arr[0];
for (NSMutableDictionary *dictionary in arr) {
  // do something using dictionary
}

os.system() returns the (encoded) process exit value. 0 means success:

On Unix, the return value is the exit status of the process encoded in the format specified for wait(). Note that POSIX does not specify the meaning of the return value of the C system() function, so the return value of the Python function is system-dependent.

The output you see is written to stdout, so your console or terminal, and not returned to the Python caller.

If you wanted to capture stdout, use subprocess.check_output() instead:

x = subprocess.check_output(['whoami'])

First

ps -ef

to list all processes. Note the the process number of the one you want to kill. Then

kill 1234

were you replace 1234 with the process number that you want.

Alternatively, if you are absolutely certain that there is only one process with a particular name, or you want to kill multiple processes which share the same name

killall processname

In one line, using a lambda:

timestamps.sort(key=lambda x: time.strptime(x, '%Y-%m-%d %H:%M:%S')[0:6], reverse=True)

Passing a function to list.sort:

def foo(x):
    return time.strptime(x, '%Y-%m-%d %H:%M:%S')[0:6]

timestamps.sort(key=foo, reverse=True)

Send a text to specific contact programmatically (Whatsapp)

try {
    val i = Intent(Intent.ACTION_VIEW)
    val url = "https://api.whatsapp.com/send?phone=91XXXXXXXXXX&text=yourmessage"
    i.setPackage("com.whatsapp")
    i.data = Uri.parse(url)
    startActivity(i)
} catch (e: Exception) {
   e.printStackTrace()
   val uri = Uri.parse("market://details?id=com.whatsapp")
   val goToMarket = Intent(Intent.ACTION_VIEW, uri)
   startActivity(goToMarket)
}

Are these structures padded or packed?

They're padded.

The only possibility that initially springs to mind, where they could be packed, is if char and int were the same size, so that the minimum size of the char/int/char structure would allow for no padding, ditto for the int/char structure.

However, that would require both sizeof(int) and sizeof(char) to be four (to get the twelve and eight sizes). The whole theory falls apart since it's guaranteed by the standard that sizeof(char) is always one.

Were char and int the same width, the sizes would be one and one, not four and four. So, in order to then get a size of twelve, there would have to be padding after the final field.

When does padding or packing take place?

Whenever the compiler implementation wants it to. Compilers are free to insert padding between fields, and following the final field (but not before the first field).

This is usually done for performance as some types perform better when they're aligned on specific boundaries. There are even some architectures that will refuse to function (i.e, crash) is you try to access unaligned data (yes, I'm looking at you, ARM).

You can generally control packing/padding (which is really opposite ends of the same spectrum) with implementation-specific features such as #pragma pack. Even if you cannot do that in your specific implementation, you can check your code at compile time to ensure it meets your requirement (using standard C features, not implementation-specific stuff).

For example:

// C11 or better ...
#include <assert.h>
struct strA { char a; int  b; char c; } x;
struct strB { int  b; char a;         } y;
static_assert(sizeof(struct strA) == sizeof(char)*2 + sizeof(int), "No padding allowed");
static_assert(sizeof(struct strB) == sizeof(char)   + sizeof(int), "No padding allowed");

Something like this will refuse to compile if there is any padding in those structures.

If you are expecting double, decimal, float, integer why not use the one which accomodates all namely decimal (128 bits are enough for most numbers you are looking at).

instead of (double)value use decimal.Parse(value.ToString()) or Convert.ToDecimal(value)

Wouldn't it just be:

SELECT CURRENT_DATE - CHDLM FROM CHCART00 WHERE CHSTAT = '05';

That should return the number of days between the two dates, if I understand how date arithmetic works in DB2 correctly.

If CHDLM isn't a date you'll have to convert it to one. According to IBM the DATE() function would not be sufficient for the yyyymmdd format, but it would work if you can format like this: yyyy-mm-dd.

For form login:

<form method="post" action="/login">
    <input type="text" id="email" name="email" size="35" maxlength="40" placeholder="Email" />
    <input type="password" id="password" name="password" size="15" maxlength="20" placeholder="Password"/>
    <input type="submit" id="send" value="Send">
</form>

Javascript:

$(document).ready(function() {    
    $('#send').prop('disabled', true);

    $('#email, #password').keyup(function(){

        if ($('#password').val() != '' && $('#email').val() != '')
        {
            $('#send').prop('disabled', false);
        }
        else
        {
            $('#send').prop('disabled', true);
        }
    });
});

Though this is old, I think question is valid even today

My suspicion is that aud should refer to the resource server(s), and the client_id should refer to one of the client applications recognized by the authentication server

Yes, aud should refer to token consuming party. And client_id refers to token obtaining party.

In my current case, my resource server is also my web app client.

In the OP's scenario, web app and resource server both belongs to same party. So this means client and audience to be same. But there can be situations where this is not the case.

Think about a SPA which consume an OAuth protected resource. In this scenario SPA is the client. Protected resource is the audience of access token.

This second scenario is interesting. There is a working draft in place named "Resource Indicators for OAuth 2.0" which explain where you can define the intended audience in your authorisation request. So the resulting token will restricted to the specified audience. Also, Azure OIDC use a similar approach where it allows resource registration and allow auth request to contain resource parameter to define access token intended audience. Such mechanisms allow OAuth adpotations to have a separation between client and token consuming (audience) party.

If you would like to prepend array (a1 with an array a2) you could use the following:

var a1 = [1, 2];
var a2 = [3, 4];
Array.prototype.unshift.apply(a1, a2);
console.log(a1);
// => [3, 4, 1, 2]

You can use card-deck, it will align all the cards... this come from bootstrap 4 official page.

      <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>

PDFCreator has a COM component, callable from .NET or VBScript (samples included in the download).

But, it seems to me that a printer is just what you need - just mix that with Word's automation, and you should be good to go.

I had to combine Maiasaura and Svun answers to get it to work: using setwd and escaping all the slashes and spaces.

setwd('C:\\Users\\firstname\ lastname\\Desktop\\folder1\\folder2\\folder3')
data = read.csv("file.csv")
data

This solved the issue for me.

If you are experiencing this error over a https connection and it's happening instantly it could be a problem setting up the SSL connection.

For me it was this issue https://github.com/nodejs/node/issues/9845 but for you it could be something else. If it is a problem with the ssl then you should be able to reproduce it with the nodejs tls/ssl package just trying to connect to the domain

For all those working with implicit rules (and GNU MAKE). Here is a simple makefile which supports different directories:

#Start of the makefile

VPATH = ./src:./header:./objects

OUTPUT_OPTION = -o objects/$@

CXXFLAGS += -Wall -g -I./header

Target = $(notdir $(CURDIR)).exe

Objects := $(notdir $(patsubst %.cpp,%.o,$(wildcard src/*.cpp)))



all: $(Target)

$(Target): $(Objects)
     $(CXX) $(CXXFLAGS) -o $(Target) $(addprefix objects/,$(Objects))


#Beware of -f. It skips any confirmation/errors (e.g. file does not exist)

.PHONY: clean
clean:
     rm -f $(addprefix objects/,$(Objects)) $(Target)

Lets have a closer look (I will refer to the current Directory with curdir):

This line is used to get a list of the used .o files which are in curdir/src.

Objects := $(notdir $(patsubst %.cpp,%.o,$(wildcard src/*.cpp)))
#expands to "foo.o myfoo.o otherfoo.o"

Via variable the output is set to a different directory (curdir/objects).

OUTPUT_OPTION = -o objects/$@
#OUTPUT_OPTION will insert the -o flag into the implicit rules

To make sure the compiler finds the objects in the new objects folder, the path is added to the filename.

$(Target): $(Objects)
     $(CXX) $(CXXFLAGS) -o $(Target) $(addprefix objects/,$(Objects))
#                                    ^^^^^^^^^^^^^^^^^^^^    

This is meant as an example and there is definitly room for improvement.

I'm using nnoremap in my .vimrc

To single quote a word:

nnoremap sq :silent! normal mpea'<Esc>bi'<Esc>`pl

To remove quotes (works on double quotes as well):

nnoremap qs :silent! normal mpeld bhd `ph<CR>

Rule to remember: 'sq' = single quote.

In Mac, Linux or Cygwin:

echo 'geo fix -99.133333 19.43333 2202' | nc localhost 5554

That will put you in Mexico City. Change your longitude/latitude/altitude accordingly. That should be enough if you are not interested in nmea.

I had this error during migration to Ubuntu 17.10, and this solved the problem :

sudo dpkg-reconfigure python3

Maybe you will have to close your session and reconnect.

Yes, you can set cookie in the AJAX request in the server-side code just as you'd do for a normal request since the server cannot differentiate between a normal request or an AJAX request.

AJAX requests are just a special way of requesting to server, the server will need to respond back as in any HTTP request. In the response of the request you can add cookies.

For some reasons, all of the answers in this thread, in onActivityResult() try to post-process the received Uri, like getting the real path of the image and then use BitmapFactory.decodeFile(path) to get the Bitmap.

This step is unnecessary. The ImageView class has a method called setImageURI(uri). Pass your uri to it and you should be done.

Uri imageUri = data.getData();
imageView.setImageURI(imageUri);

For a complete working example you could take a look here: http://androidbitmaps.blogspot.com/2015/04/loading-images-in-android-part-iii-pick.html

PS:
Getting the Bitmap in a separate variable would make sense in cases where the image to be loaded is too large to fit in memory, and a scale down operation is necessary to prevent OurOfMemoryError, like shown in the @siamii answer.

Short version:

Suppose you have two tensors, where y_hat contains computed scores for each class (for example, from y = W*x +b) and y_true contains one-hot encoded true labels.

y_hat  = ... # Predicted label, e.g. y = tf.matmul(X, W) + b
y_true = ... # True label, one-hot encoded

If you interpret the scores in y_hat as unnormalized log probabilities, then they are logits.

Additionally, the total cross-entropy loss computed in this manner:

y_hat_softmax = tf.nn.softmax(y_hat)
total_loss = tf.reduce_mean(-tf.reduce_sum(y_true * tf.log(y_hat_softmax), [1]))

is essentially equivalent to the total cross-entropy loss computed with the function softmax_cross_entropy_with_logits():

total_loss = tf.reduce_mean(tf.nn.softmax_cross_entropy_with_logits(y_hat, y_true))

Long version:

In the output layer of your neural network, you will probably compute an array that contains the class scores for each of your training instances, such as from a computation y_hat = W*x + b. To serve as an example, below I've created a y_hat as a 2 x 3 array, where the rows correspond to the training instances and the columns correspond to classes. So here there are 2 training instances and 3 classes.

import tensorflow as tf
import numpy as np

sess = tf.Session()

# Create example y_hat.
y_hat = tf.convert_to_tensor(np.array([[0.5, 1.5, 0.1],[2.2, 1.3, 1.7]]))
sess.run(y_hat)
# array([[ 0.5,  1.5,  0.1],
#        [ 2.2,  1.3,  1.7]])

Note that the values are not normalized (i.e. the rows don't add up to 1). In order to normalize them, we can apply the softmax function, which interprets the input as unnormalized log probabilities (aka logits) and outputs normalized linear probabilities.

y_hat_softmax = tf.nn.softmax(y_hat)
sess.run(y_hat_softmax)
# array([[ 0.227863  ,  0.61939586,  0.15274114],
#        [ 0.49674623,  0.20196195,  0.30129182]])

It's important to fully understand what the softmax output is saying. Below I've shown a table that more clearly represents the output above. It can be seen that, for example, the probability of training instance 1 being "Class 2" is 0.619. The class probabilities for each training instance are normalized, so the sum of each row is 1.0.

                      Pr(Class 1)  Pr(Class 2)  Pr(Class 3)
                    ,--------------------------------------
Training instance 1 | 0.227863   | 0.61939586 | 0.15274114
Training instance 2 | 0.49674623 | 0.20196195 | 0.30129182

So now we have class probabilities for each training instance, where we can take the argmax() of each row to generate a final classification. From above, we may generate that training instance 1 belongs to "Class 2" and training instance 2 belongs to "Class 1".

Are these classifications correct? We need to measure against the true labels from the training set. You will need a one-hot encoded y_true array, where again the rows are training instances and columns are classes. Below I've created an example y_true one-hot array where the true label for training instance 1 is "Class 2" and the true label for training instance 2 is "Class 3".

y_true = tf.convert_to_tensor(np.array([[0.0, 1.0, 0.0],[0.0, 0.0, 1.0]]))
sess.run(y_true)
# array([[ 0.,  1.,  0.],
#        [ 0.,  0.,  1.]])

Is the probability distribution in y_hat_softmax close to the probability distribution in y_true? We can use cross-entropy loss to measure the error.

We can compute the cross-entropy loss on a row-wise basis and see the results. Below we can see that training instance 1 has a loss of 0.479, while training instance 2 has a higher loss of 1.200. This result makes sense because in our example above, y_hat_softmax showed that training instance 1's highest probability was for "Class 2", which matches training instance 1 in y_true; however, the prediction for training instance 2 showed a highest probability for "Class 1", which does not match the true class "Class 3".

loss_per_instance_1 = -tf.reduce_sum(y_true * tf.log(y_hat_softmax), reduction_indices=[1])
sess.run(loss_per_instance_1)
# array([ 0.4790107 ,  1.19967598])

What we really want is the total loss over all the training instances. So we can compute:

total_loss_1 = tf.reduce_mean(-tf.reduce_sum(y_true * tf.log(y_hat_softmax), reduction_indices=[1]))
sess.run(total_loss_1)
# 0.83934333897877944

Using softmax_cross_entropy_with_logits()

We can instead compute the total cross entropy loss using the tf.nn.softmax_cross_entropy_with_logits() function, as shown below.

loss_per_instance_2 = tf.nn.softmax_cross_entropy_with_logits(y_hat, y_true)
sess.run(loss_per_instance_2)
# array([ 0.4790107 ,  1.19967598])

total_loss_2 = tf.reduce_mean(tf.nn.softmax_cross_entropy_with_logits(y_hat, y_true))
sess.run(total_loss_2)
# 0.83934333897877922

Note that total_loss_1 and total_loss_2 produce essentially equivalent results with some small differences in the very final digits. However, you might as well use the second approach: it takes one less line of code and accumulates less numerical error because the softmax is done for you inside of softmax_cross_entropy_with_logits().

I meet same error when start a new project. Use command line works for me.

./gradlew bootRun

You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:

import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values

... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.

Try this :

   for match in re.finditer(r"\[P[^\]]*\](.*?)\[/P\]", subject):
        # match start: match.start()
        # match end (exclusive): match.end()
        # matched text: match.group()

Use whichever suits your need.

The STL's philosophy is that you choose a container based on guarantees and not based on how the container is implemented. For example, your choice of container may be based on a need for fast lookups. For all you care, the container may be implemented as a unidirectional list -- as long as searching is very fast you'd be happy. That's because you're not touching the internals anyhow, you're using iterators or member functions for the access. Your code is not bound to how the container is implemented but to how fast it is, or whether it has a fixed and defined ordering, or whether it is efficient on space, and so on.

You can just use a simple loop: -

>>> mylist = ['10', '12', '14']
>>> for elem in mylist:
        print elem 

10
12
14

var ofd = new Microsoft.Win32.OpenFileDialog() {Filter = "JPEG Files (*.jpeg)|*.jpeg|PNG Files (*.png)|*.png|JPG Files (*.jpg)|*.jpg|GIF Files (*.gif)|*.gif"}; 
var result = ofd.ShowDialog();
if (result == false) return;
textBox1.Text = ofd.FileName;

With minor corrections:

function rearrange()
{
var windowHeight;

if (typeof window.innerWidth != 'undefined')
{
    windowHeight = window.innerHeight;
}
// IE6 in standards compliant mode (i.e. with a valid doctype as the first
// line in the document)
else if (typeof document.documentElement != 'undefined'
        && typeof document.documentElement.clientWidth != 'undefined'
        && document.documentElement.clientWidth != 0)
{
    windowHeight = document.documentElement.clientHeight;
}
// older versions of IE
else
{
    windowHeight = document.getElementsByTagName('body')[0].clientHeight;
}

document.getElementById("foobar").style.height = (windowHeight - document.getElementById("foobar").offsetTop  - 6)+ "px";
}

There's no difference between list implementations in both of your examples. There's however a difference in a way you can further use variable myList in your code.

When you define your list as:

List myList = new ArrayList();

you can only call methods and reference members that are defined in the List interface. If you define it as:

ArrayList myList = new ArrayList();

you'll be able to invoke ArrayList-specific methods and use ArrayList-specific members in addition to those whose definitions are inherited from List.

Nevertheless, when you call a method of a List interface in the first example, which was implemented in ArrayList, the method from ArrayList will be called (because the List interface doesn't implement any methods).

That's called polymorphism. You can read up on it.

angularBlogServices.factory('BlogPost', ['$resource',
    function($resource) {
        return $resource("./Post/:id", {}, {
            get:    {method: 'GET',    cache: true,  isArray: false},
            save:   {method: 'POST',   cache: false, isArray: false},
            update: {method: 'PUT',    cache: false, isArray: false},
            delete: {method: 'DELETE', cache: false, isArray: false}
        });
    }]);

set cache to be true.

An answer for the future: CSS 4 will probably contain the revert keyword, which reverts a property to its value from the user or user-agent stylesheet [source]. As of writing this, only Safari supports this – check here for updates on browser support.

In your case you would use:

.my_container ol, .my_container ul {
    list-style: revert;
}

See also this other answer with some more details.

Int32 means you have 32 bits available to store your number. The highest bit is the sign-bit, this indicates if the number is positive or negative. So you have 2^31 bits for positive and negative numbers.

With zero being a positive number you get the logical range of (mentioned before)

+2147483647 to -2147483648

If you think that is to small, use Int64:

+9223372036854775807 to -9223372036854775808

And why the hell you want to remember this number? To use in your code? You should always use Int32.MaxValue or Int32.MinValue in your code since these are static values (within the .net core) and thus faster in use than creating a new int with code.

My statement: if know this number by memory.. you're just showing off!

Just want to add for others : for some reason, I didnt not get the cell that was visible to the user when I was scrolling to previous cell in collectionView with pagingEnabled.

So I insert the code inside dispatch_async to give it some "air" and this works for me.

-(void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
    dispatch_async(dispatch_get_main_queue(), ^{
            UICollectionViewCell * visibleCell= [[self.collectionView visibleCells] objectAtIndex:0];


            [visibleCell doSomthing];
        });
}

There is cppcheck which is supported also by Hudson via the plugin of the same name.

On Windows 10, to create the virtual environment, I replace "pip mkvirtualenv myproject" by "mkvirtualenv myproject" and that works well.

Assigning $1 works but it will leave a leading space: awk '{first = $1; $1 = ""; print $0, first; }'

You can also find the number of columns in NF and use that in a loop.

As you can see here:

Specifically, @GetMapping is a composed annotation that acts as a shortcut for @RequestMapping(method = RequestMethod.GET).

Difference between @GetMapping & @RequestMapping

@GetMapping supports the consumes attribute like @RequestMapping.

If you are using Google Chrome on Linux, following command works.

Iterating through all subplots sequentially:

fig, axes = plt.subplots(nrows, ncols)

for ax in axes.flatten():
    ax.plot(x,y)

Accessing a specific index:

for row in range(nrows):
    for col in range(ncols):
        axes[row,col].plot(x[row], y[col])

As shown on Removing standard server headers on Windows Azure Web Sites page, you can remove headers with the following:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <httpProtocol>
      <customHeaders>
        <clear />
      </customHeaders>
    </httpProtocol>
    <security>
      <requestFiltering removeServerHeader="true"/>
    </security>
  </system.webServer>
  <system.web>
    <httpRuntime enableVersionHeader="false" />
  </system.web>
</configuration>

This removes the Server header, and the X- headers.

This worked locally in my tests in Visual Studio 2015.

Other answers are outdated, or incomplete, or simply don't work.

You need to also specify an X-11 server on the host machine to handle the launch of GUId programs. If the client is a Windows machine install Xming. If the client is a Linux machine install XQuartz.

Now suppose this is Windows connecting to Linux. In order to be able to launch X11 programs as well over putty do the following:

- Launch XMing on Windows client
- Launch Putty
    * Fill in basic options as you know in session category
    * Connection -> SSH -> X11
        -> Enable X11 forwarding
        -> X display location = :0.0
        -> MIT-Magic-Cookie-1
        -> X authority file for local display = point to the Xming.exe executable

Of course the ssh server should have permitted Desktop Sharing "Allow other user to view your desktop".

MobaXterm and other complete remote desktop programs work too.

Because you are talking about your replacement being anything, and also replacing in the middle of an element's children, it becomes more tricky than just inserting a singular element, or directly removing and appending:

function replaceTargetWith( targetID, html ){
  /// find our target
  var i, tmp, elm, last, target = document.getElementById(targetID);
  /// create a temporary div or tr (to support tds)
  tmp = document.createElement(html.indexOf('<td')!=-1?'tr':'div'));
  /// fill that div with our html, this generates our children
  tmp.innerHTML = html;
  /// step through the temporary div's children and insertBefore our target
  i = tmp.childNodes.length;
  /// the insertBefore method was more complicated than I first thought so I 
  /// have improved it. Have to be careful when dealing with child lists as  
  /// they are counted as live lists and so will update as and when you make
  /// changes. This is why it is best to work backwards when moving children 
  /// around, and why I'm assigning the elements I'm working with to `elm` 
  /// and `last`
  last = target;
  while(i--){
    target.parentNode.insertBefore((elm = tmp.childNodes[i]), last);
    last = elm;
  }
  /// remove the target.
  target.parentNode.removeChild(target);
}

example usage:

replaceTargetWith( 'idTABLE', 'I <b>can</b> be <div>anything</div>' );

demo:

• http://jsfiddle.net/97H5Y/1/

By using the .innerHTML of our temporary div this will generate the TextNodes and Elements we need to insert without any hard work. But rather than insert the temporary div itself -- this would give us mark up that we don't want -- we can just scan and insert it's children.

...either that or look to using jQuery and it's replaceWith method.

jQuery('#idTABLE').replaceWith('<blink>Why this tag??</blink>');

update 2012/11/15

As a response to EL 2002's comment above:

It not always possible. For example, when createElement('div') and set its innerHTML as <td>123</td>, this div becomes <div>123</div> (js throws away inappropriate td tag)

The above problem obviously negates my solution as well - I have updated my code above accordingly (at least for the td issue). However for certain HTML this will occur no matter what you do. All user agents interpret HTML via their own parsing rules, but nearly all of them will attempt to auto-correct bad HTML. The only way to achieve exactly what you are talking about (in some of your examples) is to take the HTML out of the DOM entirely, and manipulate it as a string. This will be the only way to achieve a markup string with the following (jQuery will not get around this issue either):

<table><tr>123 text<td>END</td></tr></table>

If you then take this string an inject it into the DOM, depending on the browser you will get the following:

123 text<table><tr><td>END</td></tr></table>

<table><tr><td>END</td></tr></table>

The only question that remains is why you would want to achieve broken HTML in the first place? :)

A char is only a single one-byte character. It can't store the string of characters, nor is it a pointer (which you apparently cannot have). Therefore you cannot solve your problem without using pointers (which char[] is syntactic sugar for).

I also needed what you've been searching for and did some research.

I found JSC3D (https://code.google.com/p/jsc3d/). It's a project written entirely in Javascript and uses the HTML canvas. It has been tested for Opera, Chrome, Firefox, Safari, IE9 and more.

Then you have services as p3d.in and Sketchfab that give you a nice reader to view 3D models on a web page: they use HTML5 and WebGL. They both have a free version.

For Python 3:

ListOfStrings = []
ListOfStrings.append('foo')
ListOfStrings.append('oof')
for idx, item in enumerate(ListOfStrings):
if 'foo' in item:
    ListOfStrings[idx] = "bar"

In my situation, our team don't want to keep 'packages' folder, so we put all dlls in other directory like 'sharedlib'.

I used build event to solve this problem.

if "$(ConfigurationName)" == "Release" (
goto :release
) else (
goto:exit
)

:release
if not exist $(TargetDir)\roslyn mkdir $(TargetDir)\roslyn

copy /Y "$(ProjectDir)..\..\Shared Lib\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.2.0.1\tools\Roslyn45\*" "$(TargetDir)\roslyn"
goto :exit

:exit

I know this is slightly off-topic, since some comments mentioned the ax.set_yscale('log') to be "nicest" solution I thought a rebuttal could be due. I would not recommend using ax.set_yscale('log') for histograms and bar plots. In my version (0.99.1.1) i run into some rendering problems - not sure how general this issue is. However both bar and hist has optional arguments to set the y-scale to log, which work fine.

Sometimes, although you add <uses-permission android:name="android.permission.INTERNET" /> in the AndroidManifest and you have a WiFi connection, this exception can be thrown. In my case, I have turned off WiFi and then turned it on again. This resolved the error. Weird solution, but sometimes it works.

Java 8 support a more declarative approach to iteration, in that we specify the result we want rather than how to compute it. Benefits of the new approach are that it can be more readable, less error prone.

public static void mapRemove() {

    Map<Integer, String> map = new HashMap<Integer, String>() {
        {
            put(1, "one");
            put(2, "two");
            put(3, "three");
        }
    };

    map.forEach( (key, value) -> { 
        System.out.println( "Key: " + key + "\t" + " Value: " + value );  
    }); 

    map.keySet().removeIf(e->(e>2)); // <-- remove here

    System.out.println("After removing element");

    map.forEach( (key, value) -> { 
        System.out.println( "Key: " + key + "\t" + " Value: " + value ); 
    });
}

And result is as follows:

Key: 1   Value: one
Key: 2   Value: two
Key: 3   Value: three
After removing element
Key: 1   Value: one
Key: 2   Value: two

For simple CRUD operations with a single data access point, I would say go for LINQ if you feel comfortable with the syntax. For more complicated logic I think sprocs are more efficiant performance-wise if you are good at T-SQL and its more advanced operations. You also have the help from Tuning Advisor, SQL Server Profiler, debugging your queries from SSMS etc.
