Programs & Examples On #Mousepress

With all respect the most likely thing is that you are mistaken about why the click is being 'rejected'. Why do you think some program is trying to determine if it's human or not? The Robot class (have used it a lot) should send messages that the operating system has no way to distinguish from a user doing the click.

Variation of the code by Bijaya Bidari that is accepted by Java 8 without warnings in regard with overridable method calls in constructor:

public class Graph extends JFrame {
    JPanel jp;

    public Graph() {
        super("Simple Drawing");
        super.setSize(300, 300);
        super.setDefaultCloseOperation(EXIT_ON_CLOSE);

        jp = new GPanel();
        super.add(jp);
    }

    public static void main(String[] args) {
        Graph g1 = new Graph();
        g1.setVisible(true);
    }

    class GPanel extends JPanel {
        public GPanel() {
            super.setPreferredSize(new Dimension(300, 300));
        }

        @Override
        public void paintComponent(Graphics g) {
            super.paintComponent(g);
            //rectangle originated at 10,10 and end at 240,240
            g.drawRect(10, 10, 240, 240);
                    //filled Rectangle with rounded corners.    
            g.fillRoundRect(50, 50, 100, 100, 80, 80);
        }
    }
}

A better polyfill from the MDN that supports removal of BOM and NBSP:

if (!String.prototype.trim) {
  String.prototype.trim = function () {
    return this.replace(/^[\s\uFEFF\xA0]+|[\s\uFEFF\xA0]+$/g, '');
  };
}

Bear in mind that modifying built-in prototypes comes with a performance hit (due to the JS engine bailing on a number of runtime optimizations), and in performance critical situations you may need to consider the alternative of defining myTrimFunction(string) instead. That being said, if you are targeting an older environment without native .trim() support, you are likely to have more important performance issues to deal with.

I tried installing the module locally with version and it worked!!

npm install request@^2.*

Thanks.

json.loads() takes a JSON encoded string, not a filename. You want to use json.load() (no s) instead and pass in an open file object:

with open('/Users/JoshuaHawley/clean1.txt') as jsonfile:
    data = json.load(jsonfile)

The open() command produces a file object that json.load() can then read from, to produce the decoded Python object for you. The with statement ensures that the file is closed again when done.

The alternative is to read the data yourself and then pass it into json.loads().

Here '~' refers to the root directory ,where Home is controller and Download_Excel_File is actionmethod

 <a href="~/Home/Download_Excel_File" />

My Jenkins pipeline step shown below failed with the same error.

       steps {
            echo 'Building ...' 
            sh 'sh ./Tools/build.sh'
        }

In my "build.sh" script file "docker run" command output this error when it was executed by Jenkins job. However it was working OK when the script ran in the shell terminal.The error happened because of -t option passed to docker run command that as I know tries to allocate terminal and fails if there is no terminal to allocate.

In my case I have changed the script to pass -t option only if a terminal could be detected. Here is the code after changes :

DOCKER_RUN_OPTIONS="-i --rm"

# Only allocate tty if we detect one
if [ -t 0 ] && [ -t 1 ]; then
    DOCKER_RUN_OPTIONS="$DOCKER_RUN_OPTIONS -t"
fi

docker run $DOCKER_RUN_OPTIONS --name my-container-name  my-image-tag

These are the two options I managed to build, not having the luxury of working with var type, nor with additional variables on the line:

string f = "aS.".Substring(0, "aS.".IndexOf("S"));
Console.WriteLine(f);

string s = "aS.".Split("S".ToCharArray(),StringSplitOptions.RemoveEmptyEntries)[0];
Console.WriteLine(s);

This is what it gets:

If you want the output to print to the terminal it is best to use Rscript

Rscript a.R

Note that when using R CMD BATCH a.R that instead of redirecting output to standard out and displaying on the terminal a new file called a.Rout will be created.

R CMD BATCH a.R
# Check the output
cat a.Rout

One other thing to note about using Rscript is that it doesn't load the methods package by default which can cause confusion. So if you're relying on anything that methods provides you'll want to load it explicitly in your script.

If you really want to use the ./a.R way of calling the script you could add an appropriate #! to the top of the script

#!/usr/bin/env Rscript
sayHello <- function(){
   print('hello')
}

sayHello()

I will also note that if you're running on a *unix system there is the useful littler package which provides easy command line piping to R. It may be necessary to use littler to run shiny apps via a script? Further details can be found in this question.

You may consider IaaS for file upload, such as Uploadcare. There is an Angular package for it: https://github.com/uploadcare/angular-uploadcare

Technically it's implemented as a directive, providing different options for uploading, and manipulations for uploaded images within the widget:

<uploadcare-widget
  ng-model="object.image.info.uuid"
  data-public-key="YOURKEYHERE"
  data-locale="en"
  data-tabs="file url"
  data-images-only="true"
  data-path-value="true"
  data-preview-step="true"
  data-clearable="true"
  data-multiple="false"
  data-crop="400:200"
  on-upload-complete="onUCUploadComplete(info)"
  on-widget-ready="onUCWidgetReady(widget)"
  value="{{ object.image.info.cdnUrl }}"
 />

More configuration options to play with: https://uploadcare.com/widget/configure/

It depends on what makes the most sense for your case.

Does it make sense to return null, e.g. "no such user exists"?

Or does it make sense to create a default user? This makes the most sense when you can safely assume that if a user DOESN'T exist, the calling code intends for one to exist when they ask for it.

Or does it make sense to throw an exception (a la "FileNotFound") if the calling code is demanding a user with an invalid ID?

However - from a separation of concerns/SRP standpoint, the first two are more correct. And technically the first is the most correct (but only by a hair) - GetUserById should only be responsible for one thing - getting the user. Handling its own "user does not exist" case by returning something else could be a violation of SRP. Separating into a different check - bool DoesUserExist(id) would be appropriate if you do choose to throw an exception.

Based on extensive comments below: if this is an API-level design question, this method could be analogous to "OpenFile" or "ReadEntireFile". We are "opening" a user from some repository and hydrating the object from the resultant data. An exception could be appropriate in this case. It might not be, but it could be.

All approaches are acceptable - it just depends, based on the larger context of the API/application.

(char)myint;

for example:

Console.WriteLine("(char)122 is {0}", (char)122);

yields:

(char)122 is z

No other "addClass" methods worked for me when adding a class to an 'a' element on menu except this one:

$(function () {
        var url = window.location.pathname,
    urlRegExp = new RegExp(url.replace(/\/$/, '') + "$");  
        $('a').each(function () {
                            if (urlRegExp.test(this.href.replace(/\/$/, ''))) {
                $(this).addClass('active');
            }
        });
    });

This took me four hours to find it.

After trying everything, I finally managed to get this sorted. None of the above suggested solutions worked for me. My system is A PC Windows 10. In order to get this sorted I had to change the config.json file located here C:\Users\[Your User]\AppData\Roaming\Composer\. In there, you will find:

{
    "config": {
        "disable-tls": true},
    "repositories": {
        "packagist": {
            "type": "composer",
            "url": "http://repo.packagist.org" // this needs to change to 'https'
        }
    }
}

where you need to update the packagist repo url to point to the 'https' url version.

I am aware that the above selected solution will work for 95% of the cases, but as I said, that did not work for me. Hope this helps someone.

Happy coding!

Check out Net::HTTP in the standard library. The documentation provides several examples on how to download documents using HTTP.

To answer your additional question how disable views caching:

You can do this by automatically delete the files in the folder for each request with the command php artisan view:clear mentioned by DilipGurung. Here is an example Middleware class from https://stackoverflow.com/a/38598434/2311074

<?php
namespace App\Http\Middleware;

use Artisan;
use Closure;

class ClearViewCache
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if (env('APP_DEBUG') || env('APP_ENV') === 'local') 
            Artisan::call('view:clear');

        return $next($request);
    }
}

However you may note that Larevel will recompile the files in the /app/storage/views folder whenever the time on the views files is earlier than the time on the PHP blade files for the layout. THus, I cannot really think of a scenario where this would be necessary to do.

echo $a | grep -bo cat | sed 's/:.*$//'

Personally I like the & function for this

Assuming that you are using cells A1 and A2 for John Smith

=left(a1,1) & b1

If you want to add text between, for example a period

=left(a1,1) & "." & b1

CREATE VIEW MyView AS
   SELECT Column, Value FROM Table;


SELECT Column FROM MyView WHERE Value = 1;

Is the proper solution in MySQL, some other SQLs let you define Views more exactly.

Note: Unless the View is very complicated, MySQL will optimize this just fine.

I see a lot of interesting answers that explain reference counting etc., but I am missing a simple example that demonstrates how you prevent memory leak using weak_ptr. In first example I use shared_ptr in cyclically referenced classes. When the classes go out of scope they are NOT destroyed.

#include<iostream>
#include<memory>
using namespace std;

class B;

class A
{
public:
    shared_ptr<B>bptr;
    A() {
        cout << "A created" << endl;
    }
    ~A() {
        cout << "A destroyed" << endl;
    }
};

class B
{
public:
    shared_ptr<A>aptr;
    B() {
        cout << "B created" << endl;
    }
    ~B() {
        cout << "B destroyed" << endl;
    }
};

int main()
{
    {
        shared_ptr<A> a = make_shared<A>();
        shared_ptr<B> b = make_shared<B>();
        a->bptr = b;
        b->aptr = a;
    }
  // put breakpoint here
}

If you run the code snippet you will see as classes are created, but not destroyed:

A created
B created

Now we change shared_ptr's to weak_ptr:

class B;
class A
{
public:
    weak_ptr<B>bptr;

    A() {
        cout << "A created" << endl;
    }
    ~A() {
        cout << "A destroyed" << endl;
    }
};

class B
{
public:
    weak_ptr<A>aptr;

    B() {
        cout << "B created" << endl;
    }
    ~B() {
        cout << "B destroyed" << endl;
    }
};

    int main()
    {
        {
            shared_ptr<A> a = make_shared<A>();
            shared_ptr<B> b = make_shared<B>();
            a->bptr = b;
            b->aptr = a;
        }
      // put breakpoint here
    }

This time, when using weak_ptr we see proper class destruction:

A created
B created
B destroyed
A destroyed

Here are some explanations why build_active_architecture is set to NO. Xcode now detects which devices you have connected and will set the active architecture accordingly. So if you plug a 2nd generation iPod Touch into your computer, Xcode should set the active architecture to armv6. Building your target with the above Debug configuration will now only build the armv6 binary to save time (unless you have a huge project you may not notice the difference but I guess the seconds add up over time).

When you create a Distribution configuration for publishing to the App Store, you should make sure this option is not set, so that Xcode will instead build the fat universal binary http://useyourloaf.com/blog/2010/04/21/xcode-build-active-architecture-only.html

If the original size is 100 x 100 and you want to scale it to 50 x 50, use scaledSize instead of Size.

var icon = {
    url: "../res/sit_marron.png", // url
    scaledSize: new google.maps.Size(50, 50), // scaled size
    origin: new google.maps.Point(0,0), // origin
    anchor: new google.maps.Point(0, 0) // anchor
};

var marker = new google.maps.Marker({
    position: new google.maps.LatLng(lat, lng),
    map: map,
    icon: icon
});

getJSON will evaluate the data to JSON for you, as long as the correct content-type is used. Make sure that the server is returning the data as application/json.

MSYS has not been updated a long time, MSYS2 is more active, you can download from MSYS2, it has both mingw and cygwin fork package.

To install the MinGW-w64 toolchain (Reference):

1. Open MSYS2 shell from start menu
2. Run pacman -Sy pacman to update the package database
3. Re-open the shell, run pacman -Syu to update the package database and core system packages
4. Re-open the shell, run pacman -Su to update the rest
5. Install compiler:
   • For 32-bit target, run pacman -S mingw-w64-i686-toolchain
   • For 64-bit target, run pacman -S mingw-w64-x86_64-toolchain
6. Select which package to install, default is all
7. You may also need make, run pacman -S make

If you want to achieve this just keep you dropdown button and style it like the select box. The code is here and below.

.btn {
    cursor: default;
    background-color: #FFF;
    border-radius: 4px;
    text-align: left;
}

.caret {
    position: absolute;
    right: 16px;
    top: 16px;
}

.btn-default:hover, .btn-default:focus, .btn-default:active, .btn-default.active, .open .dropdown-toggle.btn-default {
    background-color: #FFF;    
}

.btn-group.open .dropdown-toggle {
    box-shadow: 0 1px 1px rgba(0, 0, 0, 0.075) inset, 0 0 8px rgba(102, 175, 233, 0.6)
}

.btn-group {width: 100%}
.dropdown-menu {width: 100%;}

To make the button work like a select box, all you need to add is this tiny javascript code:

$('.dropdown-menu a').on('click', function(){    
    $('.dropdown-toggle').html($(this).html() + '<span class="caret"></span>');    
})

If you have multiple custom dropdowns like this you can use this javascript code:

$('.dropdown-menu a').on('click', function(){    
    $(this).parent().parent().prev().html($(this).html() + '<span class="caret"></span>');    
})

Here's something that worked for me.

@ViewChild('mapSearch', { read: ElementRef }) mapInput: ElementRef;

ngAfterViewInit() {
  interval(1000).pipe(
        switchMap(() => of(this.mapInput)),
        filter(response => response instanceof ElementRef),
        take(1))
        .subscribe((input: ElementRef) => {
          //do stuff
        });
}

So I basically set a check every second until the *ngIf becomes true and then I do my stuff related to the ElementRef.

For instance an application has two user called ap and auc. I am passing an extra property to each route and handling the routing based on the data i get in $routeChangeStart.

Try this:

angular.module("app").config(['$routeProvider',
function ($routeProvider) {

    $routeProvider.
            when('/ap', {
                templateUrl: 'template1.html',
                controller: 'template1',
                isAp: 'ap',
            }).
            when('/auc', {
                templateUrl: 'template2.html',
                controller: 'template2',
                isAp: 'common',
            }).
            when('/ic', {
                templateUrl: 'template3.html',
                controller: 'template3',
                isAp: 'auc',
            }).
            when('/mup', {
                templateUrl: 'template4.html',
                controller: 'template4',
                isAp: 'ap',
            }).

            when('/mnu', {
                templateUrl: 'template5.html',
                controller: 'template5',
                isAp: 'common',
            }).                               
            otherwise({
                redirectTo: '/ap',
            });
   }]);

app.js:

.run(['$rootScope', '$location', function ($rootScope, $location) {                
    $rootScope.$on("$routeChangeStart", function (event, next, current) {
        if (next.$$route.isAp != 'common') {
            if ($rootScope.userTypeGlobal == 1) {
                if (next.$$route.isAp != 'ap') {
                    $location.path("/ap");
                }
            }
            else {
                if (next.$$route.isAp != 'auc') {
                    $location.path("/auc");
                }                        
            }
        }

    });
}]);

Below I sum up Prateek Joshi's awesome explanation.

The theory:

• URI (uniform resource identifier) identifies a resource (text document, image file, etc)
• URL (uniform resource locator) is a subset of the URIs that include a network location
• URN (uniform resource name) is a subset of URIs that include a name within a given space, but no location

That is:

And for an example:

Also, if you haven't already, I suggest reading Roger Pate's answer.

You keep on getting new a new string and continue the loop if it's not empty. Simply insert a control in the loop for an exit string.

while(!s1.equals("exit") && sc.hasNext()) {
    // operate
}

If you want to declare the string inside the loop and not to do the operations in the loop body if the string is "exit":

while(sc.hasNext()) {
    String s1 = sc.next();
    if(s1.equals("exit")) {
        break;
    }
    //operate
}

Why are there extra spaces between my month and day? Why does't it just put them next to each other?

So your output will be aligned.

If you don't want padding use the format modifier FM:

SELECT TO_CHAR (date_field, 'fmMonth DD, YYYY') 
  FROM ...;

Reference: Format Model Modifiers

Here is a quite good but old comparison http://wiki.computerwoche.de/doku.php/programmierung/gui-builder_fuer_eclipse Window Builder Pro is now free at Google Web Toolkit

For those using bash installed on their windows system (known as Windows Subsystem for Linux (WSL)), attempting xclip will give an error:

Error: Can't open display: (null)

Instead, recall that linux subsystem has access to windows executables. It's possible to use clip.exe like

echo hello | clip.exe

which allows you to use the paste command (ctrl-v).

Since your config file is a normal text file, just read it using the open function:

file = open("abc.txt", 'r')
content = file.read()
paths = content.split("\n") #split it into lines
for path in paths:
    print path.split(" = ")[1]

This will print your paths. You can also store them using dictionaries or lists.

path_list = []
path_dict = {}
for path in paths:
    p = path.split(" = ")
    path_list.append(p)[1]
    path_dict[p[0]] = p[1]

More on reading/writing file here. Hope this helps!

Making column not null and adding default can also be done in the SSMS GUI.

1. As others have already stated, you can't set "not null" until all the existing data is "not null" like so:

UPDATE myTable SET myColumn = 0

2. Once that's done, with the table in design view (right click on table and click "design view"), you can just uncheck the Allow Nulls columns like so:

3. Still in design view with the column selected, you can see the Column Properties in the window below and set the default to 0 in there as well like so:

I'm guessing that you want something like

SELECT tab1.a, tab2.b, tab3.c, tab4.d
  FROM table1 tab1 
       JOIN table2 tab2 ON (tab1.fg = tab2.fg)
       LEFT OUTER JOIN table4 tab4 ON (tab1.ss = tab4.ss)
       LEFT OUTER JOIN table3 tab3 ON (tab4.xya = tab3.xya and tab3.desc = 'XYZ')
       LEFT OUTER JOIN table5 tab5 on (tab4.kk = tab5.kk AND
                                       tab3.dd = tab5.dd)

Personally I use this, which is similar to tarek11011's:

// Use a less-common namespace than just 'log'
function myLog(msg)
{
    // Attempt to send a message to the console
    try
    {
        console.log(msg);
    }
    // Fail gracefully if it does not exist
    catch(e){}
}

The main point is that it's a good idea to at least have some practice of logging other than just sticking console.log() right into your JavaScript code, because if you forget about it, and it's on a production site, it can potentially break all of the JavaScript code for that page.

I had this problem when upgrading my solution from Microsoft Visual Studio 2012 Express for Web to Microsoft Visual Studio 2013.

I had created a Unit Tests project in 2012, and after opening in 2013 the Unit Test project wouldn't show any tests in the tests explorer. Everytime I tried to run or debug tests it failed, saying the following in the output window:

    Failed to initialize client proxy: 
    could not connect to vstest.discoveryengine.x86.exe

I also noticed that on debugging the tests, it was launching an instance of Visual Studio 2012. This clued me into the fact that the Unit Tests project was still referencing 2012. Looking at the test project reference I realised it was targeting the wrong Microsoft Visual Studio Unit Test Framework DLL for this version of Visual Studio:

C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\PublicAssemblies\Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll

I changed the version number from 11.0 to 12.0:

C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\PublicAssemblies\Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll

I rebuilt all and this fixed the issue - all tests were found in the Test Explorer and now all tests are found and running perfectly.

A GitHub's article on line endings is commonly mentioned when talking about this topic.

My personal experience with using the often recommended core.autocrlf config setting was very mixed.

I'm using Windows with Cygwin, dealing with both Windows and UNIX projects at different times. Even my Windows projects sometimes use bash shell scripts, which require UNIX (LF) line endings.

Using GitHub's recommended core.autocrlf setting for Windows, if I check out a UNIX project (which does work perfectly on Cygwin - or maybe I'm contributing to a project that I use on my Linux server), the text files are checked out with Windows (CRLF) line endings, creating problems.

Basically, for a mixed environment like I have, setting the global core.autocrlf to any of the options will not work well in some cases. This option might be set on a local (repository) git config, but even that wouldn't be good enough for a project that contains both Windows- and UNIX-related stuff (e.g. I have a Windows project with some bash utility scripts).

The best choice I've found is to create per-repository .gitattributes files. The GitHub article mentions it.
Example from that article:

# Set the default behavior, in case people don't have core.autocrlf set.
* text=auto

# Explicitly declare text files you want to always be normalized and converted
# to native line endings on checkout.
*.c text
*.h text

# Declare files that will always have CRLF line endings on checkout.
*.sln text eol=crlf

# Denote all files that are truly binary and should not be modified.
*.png binary
*.jpg binary

In one of my project's repository:

* text=auto

*.txt         text eol=lf
*.xml         text eol=lf
*.json        text eol=lf
*.properties  text eol=lf
*.conf        text eol=lf

*.awk  text eol=lf
*.sed  text eol=lf
*.sh   text eol=lf

*.png  binary
*.jpg  binary

*.p12  binary

It's a bit more things to set up, but do it once per project, and any contributor on any OS should have no troubles with line endings when working with this project.

new Integer(i).toString() first creates a (redundant) wrapper object around i (which itself may be a wrapper object Integer).

Integer.toString(i) is preferred because it doesn't create any unnecessary objects.

The _stats command provides ways to customize the results by specifying the metrics wished. To get the indices the query is as follows:

GET /_stats/indices

The general format of the _stats query is:

/_stats
/_stats/{metric}
/_stats/{metric}/{indexMetric}
/{index}/_stats
/{index}/_stats/{metric}

Where the metrics are:

indices, docs, store, indexing, search, get, merge, 
refresh, flush, warmer, filter_cache, id_cache, 
percolate, segments, fielddata, completion

As an exercice to myself, I've written a small elasticsearch plugin providing the functionality to list elasticsearch indices without any other information. You can find it at the following url:

http://blog.iterativ.ch/2014/04/11/listindices-writing-your-first-elasticsearch-java-plugin/

If you are getting following exception:

Error: Commit failed (details follow):
Error: Commit blocked by pre-commit hook (exit code 1) with output:
Error: svnlook: Path 'trunk/Development/ProjectName' is not a file

Then first check-in all the the directories and then all the files. It will work.

When GROUP BY is not used, the WHERE and HAVING clauses are essentially equivalent.

However, when GROUP BY is used:

• The WHERE clause is used to filter records from a result. The filtering occurs before any groupings are made.
• The HAVING clause is used to filter values from a group (i.e., to check conditions after aggregation into groups has been performed).

Understanding the terms:

This picture should give you the idea about the context in which the words breadth and depth are used.

Depth-First Search:

• Depth-first search algorithm acts as if it wants to get as far away from the starting point as quickly as possible.

• It generally uses a Stack to remember where it should go when it reaches a dead end.

• Rules to follow: Push first vertex A on to the Stack

  1. If possible, visit an adjacent unvisited vertex, mark it as visited, and push it on the stack.
  2. If you can’t follow Rule 1, then, if possible, pop a vertex off the stack.
  3. If you can’t follow Rule 1 or Rule 2, you’re done.

• Java code:

  public void searchDepthFirst() {
      // Begin at vertex 0 (A)
      vertexList[0].wasVisited = true;
      displayVertex(0);
      stack.push(0);
      while (!stack.isEmpty()) {
          int adjacentVertex = getAdjacentUnvisitedVertex(stack.peek());
          // If no such vertex
          if (adjacentVertex == -1) {
              stack.pop();
          } else {
              vertexList[adjacentVertex].wasVisited = true;
              // Do something
              stack.push(adjacentVertex);
          }
      }
      // Stack is empty, so we're done, reset flags
      for (int j = 0; j < nVerts; j++)
          vertexList[j].wasVisited = false;
  }
  

• Applications: Depth-first searches are often used in simulations of games (and game-like situations in the real world). In a typical game you can choose one of several possible actions. Each choice leads to further choices, each of which leads to further choices, and so on into an ever-expanding tree-shaped graph of possibilities.

Breadth-First Search:

• The breadth-first search algorithm likes to stay as close as possible to the starting point.
• This kind of search is generally implemented using a Queue.
• Rules to follow: Make starting Vertex A the current vertex
  1. Visit the next unvisited vertex (if there is one) that’s adjacent to the current vertex, mark it, and insert it into the queue.
  2. If you can’t carry out Rule 1 because there are no more unvisited vertices, remove a vertex from the queue (if possible) and make it the current vertex.
  3. If you can’t carry out Rule 2 because the queue is empty, you’re done.

• Java code:

  public void searchBreadthFirst() {
      vertexList[0].wasVisited = true;
      displayVertex(0);
      queue.insert(0);
      int v2;
      while (!queue.isEmpty()) {
          int v1 = queue.remove();
          // Until it has no unvisited neighbors, get one
          while ((v2 = getAdjUnvisitedVertex(v1)) != -1) {
              vertexList[v2].wasVisited = true;
              // Do something
              queue.insert(v2);
          }
      }
      // Queue is empty, so we're done, reset flags
      for (int j = 0; j < nVerts; j++) 
          vertexList[j].wasVisited = false;
  }
  

• Applications: Breadth-first search first finds all the vertices that are one edge away from the starting point, then all the vertices that are two edges away, and so on. This is useful if you’re trying to find the shortest path from the starting vertex to a given vertex.

Hopefully that should be enough for understanding the Breadth-First and Depth-First searches. For further reading I would recommend the Graphs chapter from an excellent data structures book by Robert Lafore.

You can also get a query string value as:

$uri =  $_SERVER["REQUEST_URI"]; //it will print full url
$uriArray = explode('/', $uri); //convert string into array with explode
$id = $uriArray[1]; //Print first array value

here is the solution

if (
  document.getElementById('73536573').value != '' &&
  document.getElementById('1081743273').value != '' &&
  document.getElementById('357118391').value != '' &&
  document.getElementById('1238321094').value != '' &&
  document.getElementById('1118122010').value != ''
  ) {

  }

As Alex Burtsev mentioned in a comment anything that’s only used in a XAML resource dictionary, or in my case, anything that’s only used in XAML and not in code behind, isn't deemed to be 'in use' by MSBuild.

So simply new-ing up a dummy reference to a class/component in the assembly in some code behind was enough convince MSBuild that the assembly was actually in use.

A call to your parent class's empty constructor super() is done automatically when you don't do it yourself. That's the reason you've never had to do it in your code. It was done for you.

When your superclass doesn't have a no-arg constructor, the compiler will require you to call super with the appropriate arguments. The compiler will make sure that you instantiate the class correctly. So this is not something you have to worry about too much.

Whether you call super() in your constructor or not, it doesn't affect your ability to call the methods of your parent class.

As a side note, some say that it's generally best to make that call manually for reasons of clarity.

You just add following lines of code in style.xml file

<style name="AppTheme.NoTitleBar" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>

change apptheme in AndroidManifest.xml file

android:theme="@style/AppTheme.NoTitleBar"

If your application often uses http protocol then REST is best because of its light weight, and knowing that your application uses only http protocol choosing SOAP is not so good because it heavy,Better to make decision on web service selection based on the protocols we use in our applications.

No need to include CSS or image files. No need to include that whole heavy-artillery jQuery UI library. I wrote a lightweight jQuery plugin that does the magic for you. All you need is jQuery and the plugin. =)

Fiddle here: jQuery InputSearch demo.

I tried running @Viraj Wadate's code, but couldn't get the output from app.logger.info on the console.

To get INFO, WARNING, and ERROR messages in the console, the dictConfig object can be used to create logging configuration for all logs (source):

from logging.config import dictConfig
from flask import Flask


dictConfig({
    'version': 1,
    'formatters': {'default': {
        'format': '[%(asctime)s] %(levelname)s in %(module)s: %(message)s',
    }},
    'handlers': {'wsgi': {
        'class': 'logging.StreamHandler',
        'stream': 'ext://flask.logging.wsgi_errors_stream',
        'formatter': 'default'
    }},
    'root': {
        'level': 'INFO',
        'handlers': ['wsgi']
    }
})


app = Flask(__name__)

@app.route('/')
def index():
    return "Hello from Flask's test environment"

@app.route('/print')
def printMsg():
    app.logger.warning('testing warning log')
    app.logger.error('testing error log')
    app.logger.info('testing info log')
    return "Check your console"

if __name__ == '__main__':
    app.run(debug=True)

Well, found a solution to my problem; Updating all rows using a SQL query and a SQL Task in SSIS Like Below. May help others if they face same challenge in future.

update Original 
set Original.Vaal= t.vaal 
from Original join (select * from staging1  union   select * from staging2) t 
on Original.id=t.id

Using zsh you can simply use:

if [[ $(false)? -eq 1 ]]; then echo "yes" ;fi

When using bash & set -e is on you can use:

false || exit_code=$?
if [[ ${exit_code} -ne 0 ]]; then echo ${exit_code}; fi

http://www.cplusplus.com/reference/ctime/strftime/

This built-in seems to offer a reasonable set of options.

You can do it very easily.

ALTER TABLE `table_name` CHANGE COLUMN `column_name` `column_name` LONGTEXT NULL DEFAULT NULL ;

The above query worked for me. I hope it helps you too.

Whenever I set debug="off" in my web.config and run my mvc4 application i would end up with ...

<script src="/bundles/jquery?v=<some long string>"></script>

in my html code and a JavaScript error

Expected ';'

There were 2 ways to get rid of the javascript error

1. set BundleTable.EnableOptimizations = false in BundleConfig.cs

OR

2. I ended up using NuGet Package Manager to update WebGrease.dll. It works fine irrespective if debug= "true" or debug = "false".

String to Time (using an arbitrary time):

String myTime = "10:00:00"; 
Time startingTime = new Time (myTime);

String to Time (using currentTime):

String currentTime = getCurrentTime(); 
Time startingTime = new Time (currentTime);

Time to String:

private String getCurrentTime() {    
    SimpleDateFormat dateFormat = new SimpleDateFormat("kkmmss");
    String currentTime = dateFormat.format(System.currentTimeMillis());
    return currentTime;
}

Here is the correct implementation using numpy (np.log() is the natural logarithm)

import numpy as np
p = 100
r = 0.06 / 12
FV = 4000

n = np.log(1 + FV * r/ p) / np.log(1 + r)

print ("Number of periods = " + str(n))

Output:

Number of periods = 36.55539635919235

If you are using RC5 then import this:

import { CommonModule } from '@angular/common';  
import { BrowserModule } from '@angular/platform-browser';

and be sure to import CommonModule from the module that is providing your component.

 @NgModule({
    imports: [CommonModule],
    declarations: [MyComponent]
  ...
})
class MyComponentModule {}

Try this code:

String strProc =

         "" +
         "   SELECT SYSDATE INTO sys_date FROM dual;\n" +
         "" +
         "END;\n";

    PreparedStatement psProcToexecute = connection.prepareStatement(strProc);
    psProcToexecute.execute();
}catch (Exception e) {
    System.out.println(e.toString());  
}

Actually I want timestamp based shorter unique identifier, hence tried the below program.

It is guessable with nanosecond + ( endians.length * endians.length ) combinations.

            'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 
            'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 
            'U', 'V', 'W', 'X', 'Y', 'Z',
            '0', '1', '2', '3', '4', '5', '6', '7', '8', '9'

    public static String generateShorterTxnId() {
        // Keep this as secure random when we want more secure, in distributed systems
        int firstLetter = ThreadLocalRandom.current().nextInt(0, (endians.length));

        //Sometimes your randomness and timestamp will be same value,
        //when multiple threads are trying at the same nano second
        //time hence to differentiate it, utilize the threads requesting
        //for this value, the possible unique thread numbers == endians.length
        Character secondLetter = threadLocal.get();
        if (secondLetter == null) {
            synchronized (threadLocal) {
                if (secondLetter == null) {

UPDATE: This code will work on single JVM, but we should think on distributed JVM, hence i am thinking two solutions one with DB and another one without DB.

with DB

Company name (shortname 3 chars) ---- Random_Number ---- Key specific redis COUNTER
(3 char) ------------------------------------------------ (2 char) ---------------- (11 char)

without DB

IPADDRESS ---- THREAD_NUMBER ---- INCR_NUMBER ---- epoch milliseconds
(5 chars) ----------------- (2char) ----------------------- (2 char) ----------------- (6 char)

will update you once coding is done.

You can just simply use this.. short and easy.

I was having the same problem in many places, so I created a convenience package horology. You can install it with pip install horology and then do it in the elegant way:

from horology import Timing

with Timing(name='Important calculations: '):
    prepare()
    do_your_stuff()
    finish_sth()

will output:

Important calculations: 12.43 ms

Or even simpler (if you have one function):

from horology import timed

@timed
def main():
    ...

will output:

main: 7.12 h

It takes care of units and rounding. It works with python 3.6 or newer.

Depending on what you plan to do with your sentence-as-a-list, you may want to look at the Natural Language Took Kit. It deals heavily with text processing and evaluation. You can also use it to solve your problem:

import nltk
words = nltk.word_tokenize(raw_sentence)

This has the added benefit of splitting out punctuation.

Example:

>>> import nltk
>>> s = "The fox's foot grazed the sleeping dog, waking it."
>>> words = nltk.word_tokenize(s)
>>> words
['The', 'fox', "'s", 'foot', 'grazed', 'the', 'sleeping', 'dog', ',', 
'waking', 'it', '.']

This allows you to filter out any punctuation you don't want and use only words.

Please note that the other solutions using string.split() are better if you don't plan on doing any complex manipulation of the sentence.

For Visual Studio 2017 and its new .csproj format

You can no longer just use Install-Package to point to a local file. (That's likely because the PackageReference element doesn't support file paths; it only allows you to specify the package's Id.)

You first have to tell Visual Studio about the location of your package, and then you can add it to a project. What most people do is go into the NuGet Package Manager and add the local folder as a source (menu Tools ? Options ? NuGet Package Manager ? Package Sources). But that means your dependency's location isn't committed (to version-control) with the rest of your codebase.

Local NuGet packages using a relative path

This will add a package source that only applies to a specific solution, and you can use relative paths.

You need to create a nuget.config file in the same directory as your .sln file. Configure the file with the package source(s) you want. When you next open the solution in Visual Studio 2017, any .nupkg files from those source folders will be available. (You'll see the source(s) listed in the Package Manager, and you'll find the packages on the "Browse" tab when you're managing packages for a project.)

Here's an example nuget.config to get you started:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <packageSources>
        <add key="MyLocalSharedSource" value="..\..\..\some\folder" />
    </packageSources>
</configuration>

Backstory

My use case for this functionality is that I have multiple instances of a single code repository on my machine. There's a shared library within the codebase that's published/deployed as a .nupkg file. This approach allows the various dependent solutions throughout our codebase to use the package within the same repository instance. Also, someone with a fresh install of Visual Studio 2017 can just checkout the code wherever they want, and the dependent solutions will successfully restore and build.

Steps:

1. "gulp": "^3.9.1",
2. npm install
3. gulp styles

You should be able to get an IWin32Window by by using PresentationSource.FromVisual and casting the result to HwndSource which implements IWin32Window.

Also in the comments here:

On some mobiles like mine (MIUI Redmi 3) you can just add specific Application on list where application doesnt stop when you terminate applactions in Task Manager (It will stop but it will start again)

Just go to Settings>PermissionsAutostart

The answers above are perfectly valid, but a vectorized solution exists, in the form of numpy.select. This allows you to define conditions, then define outputs for those conditions, much more efficiently than using apply:

First, define conditions:

conditions = [
    df['eri_hispanic'] == 1,
    df[['eri_afr_amer', 'eri_asian', 'eri_hawaiian', 'eri_nat_amer', 'eri_white']].sum(1).gt(1),
    df['eri_nat_amer'] == 1,
    df['eri_asian'] == 1,
    df['eri_afr_amer'] == 1,
    df['eri_hawaiian'] == 1,
    df['eri_white'] == 1,
]

Now, define the corresponding outputs:

outputs = [
    'Hispanic', 'Two Or More', 'A/I AK Native', 'Asian', 'Black/AA', 'Haw/Pac Isl.', 'White'
]

Finally, using numpy.select:

res = np.select(conditions, outputs, 'Other')
pd.Series(res)

0           White
1        Hispanic
2           White
3           White
4           Other
5           White
6     Two Or More
7           White
8    Haw/Pac Isl.
9           White
dtype: object

Why should numpy.select be used over apply? Here are some performance checks:

df = pd.concat([df]*1000)

In [42]: %timeit df.apply(lambda row: label_race(row), axis=1)
1.07 s ± 4.16 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

In [44]: %%timeit
    ...: conditions = [
    ...:     df['eri_hispanic'] == 1,
    ...:     df[['eri_afr_amer', 'eri_asian', 'eri_hawaiian', 'eri_nat_amer', 'eri_white']].sum(1).gt(1),
    ...:     df['eri_nat_amer'] == 1,
    ...:     df['eri_asian'] == 1,
    ...:     df['eri_afr_amer'] == 1,
    ...:     df['eri_hawaiian'] == 1,
    ...:     df['eri_white'] == 1,
    ...: ]
    ...:
    ...: outputs = [
    ...:     'Hispanic', 'Two Or More', 'A/I AK Native', 'Asian', 'Black/AA', 'Haw/Pac Isl.', 'White'
    ...: ]
    ...:
    ...: np.select(conditions, outputs, 'Other')
    ...:
    ...:
3.09 ms ± 17 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Using numpy.select gives us vastly improved performance, and the discrepancy will only increase as the data grows.

sparkContext.setLogLevel("OFF")

try this

var value = iterate('tr.item span.value');
var quantity = iterate('tr.item span.quantity');

function iterate(selector)
{
  var result = '';
  if ($(selector))
  {
    $(selector).each(function ()
    {
      if (result == '')
      {
        result = $(this).html();
      }
      else
      {
        result = result + "," + $(this).html();
      }
    });
  }
}

My vote is string.Join

No need for lambda evaluations and temporary functions to be created, fewer function calls, less stack pushing and popping.

This is what I use and it works for most cases unless the user decides to override it by pressing shift or caps lock. Like on Android and iOS keyboards.

Private Class ProperCaseHandler
    Private Const wordbreak As String = " ,.1234567890;/\-()#$%^&*€!~+=@"

        txtProperCase = txt
        AddHandler txt.KeyPress, AddressOf txtTextKeyDownProperCase
    End Sub

    Private Sub txtTextKeyDownProperCase(ByVal sender As System.Object, ByVal e As Windows.Forms.KeyPressEventArgs)
        Try
            If Control.IsKeyLocked(Keys.CapsLock) Or Control.ModifierKeys = Keys.Shift Then
                Exit Sub
            Else
                If txtProperCase.TextLength = 0 Then
                    e.KeyChar = e.KeyChar.ToString.ToUpper()
                    e.Handled = False
                Else
                    Dim lastChar As String = txtProperCase.Text.Substring(txtProperCase.SelectionStart - 1, 1)

                    If wordbreak.Contains(lastChar) = True Then
                        e.KeyChar = e.KeyChar.ToString.ToUpper()
                        e.Handled = False
                    End If
                End If

            End If

        Catch ex As Exception
            Exit Sub
        End Try
    End Sub
End Class

The solution for those who use composer is to use a volume pointing to the parent folder:

#docker-composer.yml

foo:
  build: foo
  volumes:
    - ./:/src/:ro

But I'm pretty sure the can be done playing with volumes in Dockerfile.

Check How to: Define Constants in C# on MSDN:

In C# the #define preprocessor directive cannot be used to define constants in the way that is typically used in C and C++.

The best approach to use yum and update your devtoolset is to utilize the CentOS SCLo RH Testing repository.

yum install centos-release-scl-rh
yum --enablerepo=centos-sclo-rh-testing install devtoolset-7-gcc devtoolset-7-gcc-c++

Many additional packages are also available, to see them all

yum --enablerepo=centos-sclo-rh-testing list devtoolset-7*

You can use this method to install any dev tool version, just swap the 7 for your desired version. devtoolset-6-gcc, devtoolset-5-gcc etc.

import xlwt

def output(filename, sheet, list1, list2, x, y, z):

    x_desc = 'Display'
    y_desc = 'Dominance'
    z_desc = 'Test'
    desc = [x_desc, y_desc, z_desc]

    col1_name = 'Stimulus Time'
    col2_name = 'Reaction Time'

    #You may need to group the variables together
    #for n, (v_desc, v) in enumerate(zip(desc, variables)):
    for n, v_desc, v in enumerate(zip(desc, variables)):
        sh.write(n, 0, v_desc)
        sh.write(n, 1, v)

    n+=1

    sh.write(n, 0, col1_name)
    sh.write(n, 1, col2_name)

    for m, e1 in enumerate(list1, n+1):

If you are looking for a brand new pull from another branch like from local to master you can follow this.

git commit -m "Initial Commit"
git add .
git pull --rebase git_url
git push origin master

This is a user-defined function to iterate through a dictionary:

func findDic(dict: [String: String]){
    for (key, value) in dict{
    print("\(key) : \(value)")
  }
}

findDic(dict: ["Animal":"Lion", "Bird":"Sparrow"])
//prints Animal : Lion 
         Bird : Sparrow

I'd be careful about trying to get too clever here. I think it's confusing as it is and using more advanced nth-child parameters will only make it more complicated. As for the background color I'd just set that to a variable.

Here goes what I came up with before I realized trying to be too clever might be a bad thing.

#romtest {
 $bg: #e5e5e5;
 .detailed {
    th {
      &:nth-child(-2n+6) {
        background-color: $bg;
      }
    }
    td {
      &:nth-child(3n), &:nth-child(2), &:nth-child(7) {
        background-color: $bg;
      }
      &.last {
        &:nth-child(-2n+4){
          background-color: $bg;
        }
      }
    }
  }
}

and here is a quick demo: http://codepen.io/anon/pen/BEImD

----EDIT----

Here's another approach to avoid retyping background-color:

#romtest {
  %highlight {
    background-color: #e5e5e5; 
  }
  .detailed {
    th {
      &:nth-child(-2n+6) {
        @extend %highlight;
      }
    }

    td {
      &:nth-child(3n), &:nth-child(2), &:nth-child(7) {
        @extend %highlight;
      }
      &.last {
        &:nth-child(-2n+4){
          @extend %highlight;
        }
      }
    }
  }
}

there are some flavours of shutdown: http://msdn.microsoft.com/en-us/library/system.net.sockets.socket.shutdown.aspx. *nix is similar.

1. Run 'path' in command prompt and ensure that the maven installation directory is listed.
2. Ensure the maven is installed in 'C:\Program Files\Maven'.

To execute it with Bash, use #!/bin/bash and chmod it to be executable, then use

./choose.sh

To add to other questions, let me provide how I did it with a Python 2.0 function using Numpy:

def one_hot(y_):
    # Function to encode output labels from number indexes 
    # e.g.: [[5], [0], [3]] --> [[0, 0, 0, 0, 0, 1], [1, 0, 0, 0, 0, 0], [0, 0, 0, 1, 0, 0]]

    y_ = y_.reshape(len(y_))
    n_values = np.max(y_) + 1
    return np.eye(n_values)[np.array(y_, dtype=np.int32)]  # Returns FLOATS

The line n_values = np.max(y_) + 1 could be hard-coded for you to use the good number of neurons in case you use mini-batches for example.

Demo project/tutorial where this function has been used: https://github.com/guillaume-chevalier/LSTM-Human-Activity-Recognition

You can also put your templates folder under src/main/resources instead of src/main/java. Works for me and it's a preferable location since templates are not java source.

The message is fairly self-explanatory; your working directory should not be the NumPy source directory when you invoke Python; NumPy should be installed and your working directory should be anything but the directory where it lives.

Webdriver doesn't contain an API to do it. See issue 141 from Selenium tracker for more info. The title of the issue says that it's about response headers but it was decided that Selenium won't contain API for request headers in scope of this issue. Several issues about adding API to set request headers have been marked as duplicates: first, second, third.

Here are a couple of possibilities that I can propose:

1. Use another driver/library instead of selenium
2. Write a browser-specific plugin (or find an existing one) that allows you to add header for request.
3. Use browsermob-proxy or some other proxy.

I'd go with option 3 in most of cases. It's not hard.

Note that Ghostdriver has an API for it but it's not supported by other drivers.

Since it is a numeric operation, we should be converting it to numeric form first. This operation cannot take place if the data is in factor data type.
Check the data type of the columns using str().

min(as.numeric(data[,2]))

In batch you could do it like this:

@echo off

setlocal EnableDelayedExpansion

set "string_list=str1 str2 str3 ... str10"

for %%s in (%string_list%) do (
  set "var=%%sxyz"
  svn co "!var!"
)

If you don't need the variable !var! elsewhere in the loop, you could simplify that to

@echo off

setlocal

set "string_list=str1 str2 str3 ... str10"

for %%s in (%string_list%) do svn co "%%sxyz"

However, like C.B. I'd prefer PowerShell if at all possible:

$string_list = 'str1', 'str2', 'str3', ... 'str10'

$string_list | ForEach-Object {
  $var = "${_}xyz"   # alternatively: $var = $_ + 'xyz'
  svn co $var
}

Again, this could be simplified if you don't need $var elsewhere in the loop:

$string_list = 'str1', 'str2', 'str3', ... 'str10'
$string_list | ForEach-Object { svn co "${_}xyz" }

To get last month's first date:

select DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE())-1, 0) LastMonthFirstDate                                                                

To get last month's last date:

select DATEADD(MONTH, DATEDIFF(MONTH, -1, GETDATE())-1, -1) LastMonthEndDate

Presumably from this site:

Internal Fragmentation Internal fragmentation occurs when the memory allocator leaves extra space empty inside of a block of memory that has been allocated for a client. This usually happens because the processor’s design stipulates that memory must be cut into blocks of certain sizes -- for example, blocks may be required to be evenly be divided by four, eight or 16 bytes. When this occurs, a client that needs 57 bytes of memory, for example, may be allocated a block that contains 60 bytes, or even 64. The extra bytes that the client doesn’t need go to waste, and over time these tiny chunks of unused memory can build up and create large quantities of memory that can’t be put to use by the allocator. Because all of these useless bytes are inside larger memory blocks, the fragmentation is considered internal.

External Fragmentation External fragmentation happens when the memory allocator leaves sections of unused memory blocks between portions of allocated memory. For example, if several memory blocks are allocated in a continuous line but one of the middle blocks in the line is freed (perhaps because the process that was using that block of memory stopped running), the free block is fragmented. The block is still available for use by the allocator later if there’s a need for memory that fits in that block, but the block is now unusable for larger memory needs. It cannot be lumped back in with the total free memory available to the system, as total memory must be contiguous for it to be useable for larger tasks. In this way, entire sections of free memory can end up isolated from the whole that are often too small for significant use, which creates an overall reduction of free memory that over time can lead to a lack of available memory for key tasks.

You need to set up your global core.excludesfile configuration file to point to this global ignore file.

e.g.

*nix or Windows git bash:

git config --global core.excludesFile '~/.gitignore'

Windows cmd:

git config --global core.excludesFile "%USERPROFILE%\.gitignore"

Windows PowerShell:

git config --global core.excludesFile "$Env:USERPROFILE\.gitignore"

For Windows it set to the location C:\Users\{myusername}\.gitignore. You can verify that the config value is correct by doing:

git config --global core.excludesFile

The result should be the expanded path to your user profile's .gitignore. Ensure that the value does not contain the unexpanded %USERPROFILE% string.

Important: The above commands will only set the location of the ignore file that git will use. The file has to still be manually created in that location and populated with the ignore list. (from muruge's comment)

You can read about the command at https://help.github.com/articles/ignoring-files/#create-a-global-gitignore

JSDB, available for Linux, Windows, and Mac should fit the bill pretty well. It uses Mozilla's Spidermonkey Javascript engine and seems to be less of a hassle to install compared to node.js (at least last time I tried node.js a couple of years ago).

I found JSDB from this interesting list of Javascript shells: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Shells

IIRC the purpose of the form method attribute was to define different transport methods. Consequently, HTML 5.2 only defines GET, POST, and DIALOG methods for transport and dialog action, not how the server should process the data.

Ruby-on-rails solves this problem by using POST/GET for everything and adding a hidden form variable that defines the actual ReST method. This approach is more clumsy and error-prone, but does remove the burden from both the HTML standard and browser developers.

The form method was defined before ReST, so you cannot define ReST in HTML, even after enabling Apache and PHP because the browsers conform to HTML and therefore default to GET/POST for all non-HTML defined values. That means, when you send a form to the browser with a PUT method, the browser changes that to GET and uses that instead. The hidden variable, however, passes through everything unchanged, so you can use that to customise your form handling process.

Hope that helps

I believe that must-revalidate means :

Once the cache expires, refuse to return stale responses to the user even if they say that stale responses are acceptable.

Whereas no-cache implies :

must-revalidate plus the fact the response becomes stale right away.

If a response is cacheable for 10 seconds, then must-revalidate kicks in after 10 seconds, whereas no-cache implies must-revalidate after 0 seconds.

At least, that's my interpretation.

I got the same message ("repository element was not specified in the POM inside distributionManagement element"). I checked /target/checkout/pom.xml and as per another answer and it really lacked <distributionManagement>.

It turned out that the problem was that <distributionManagement> was missing in pom.xml in my master branch (using git).

After cleaning up (mvn release:rollback, mvn clean, mvn release:clean, git tag -d v1.0.0) I run mvn release again and it worked.

$("#datePicker").datePicker({startDate: new Date() });. This works for me

An easier way to do this in the current stable version (1.0.6) requires a lot less code.

After setting up your module add a factory:

var app = angular.module('myApp', []);
// Configure routes and controllers and views associated with them.
app.config(function ($routeProvider) {
    // route setups
});
app.factory('MyCache', function ($cacheFactory) {
    return $cacheFactory('myCache');
});

Now you can pass this into your controller:

app.controller('MyController', function ($scope, $http, MyCache) {
    $http.get('fileInThisCase.json', { cache: MyCache }).success(function (data) {
        // stuff with results
    });
});

One downside is that the key names are also setup automatically, which could make clearing them tricky. Hopefully they'll add in some way to get key names.

Like this:

var $aWithId = $('.parent a[id]');

Following OP's comment, test it like this:

if($aWithId.length) //or without using variable: if ($('.parent a[id]').length)

Will return all anchor tags inside elements with class parent which have an attribute ID specified

You can access the iterator methods directly:

std::vector<int> *intVec;
std::vector<int>::iterator it;

for( it = intVec->begin(); it != intVec->end(); ++it )
{
}

If you want the array-access operator, you'd have to de-reference the pointer. For example:

std::vector<int> *intVec;

int val = (*intVec)[0];

Let's start with the explanation of why do you see these warnings in the first place.

Most probably you have not installed TF from source and instead of it used something like pip install tensorflow. That means that you installed pre-built (by someone else) binaries which were not optimized for your architecture. And these warnings tell you exactly this: something is available on your architecture, but it will not be used because the binary was not compiled with it. Here is the part from documentation.

TensorFlow checks on startup whether it has been compiled with the optimizations available on the CPU. If the optimizations are not included, TensorFlow will emit warnings, e.g. AVX, AVX2, and FMA instructions not included.

Good thing is that most probably you just want to learn/experiment with TF so everything will work properly and you should not worry about it

What are SSE4.2 and AVX?

Wikipedia has a good explanation about SSE4.2 and AVX. This knowledge is not required to be good at machine-learning. You may think about them as a set of some additional instructions for a computer to use multiple data points against a single instruction to perform operations which may be naturally parallelized (for example adding two arrays).

Both SSE and AVX are implementation of an abstract idea of SIMD (Single instruction, multiple data), which is

a class of parallel computers in Flynn's taxonomy. It describes computers with multiple processing elements that perform the same operation on multiple data points simultaneously. Thus, such machines exploit data level parallelism, but not concurrency: there are simultaneous (parallel) computations, but only a single process (instruction) at a given moment

This is enough to answer your next question.

How do these SSE4.2 and AVX improve CPU computations for TF tasks

They allow a more efficient computation of various vector (matrix/tensor) operations. You can read more in these slides

How to make Tensorflow compile using the two libraries?

You need to have a binary which was compiled to take advantage of these instructions. The easiest way is to compile it yourself. As Mike and Yaroslav suggested, you can use the following bazel command

bazel build -c opt --copt=-mavx --copt=-mavx2 --copt=-mfma --copt=-mfpmath=both --copt=-msse4.2 --config=cuda -k //tensorflow/tools/pip_package:build_pip_package

This is the shortest version I could find,saving/hiding an extra conversion:

pil_image = PIL.Image.open('image.jpg')
opencvImage = cv2.cvtColor(numpy.array(pil_image), cv2.COLOR_RGB2BGR)

If reading a file from a URL:

import cStringIO
import urllib
file = cStringIO.StringIO(urllib.urlopen(r'http://stackoverflow.com/a_nice_image.jpg').read())
pil_image = PIL.Image.open(file)
opencvImage = cv2.cvtColor(numpy.array(pil_image), cv2.COLOR_RGB2BGR)

Am adding few things related to jenkins configuration files storage.

As per my understanding all config file stores in the machine or OS that you have installed jenkins.

The jobs you are going to create in jenkins will be stored in jenkins server and you can find the config.xml etc., here.

After jenkins installation you will find jenkins workspace in server.

*cd>jenkins/jobs/`
cd>jenkins/jobs/$ls
   job1 job2 job3 config.xml ....*

Just put ScriptManager inside form tag like this:

<form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager> 

If it has Master Page then Put this in the Master Page itself.

If you are using a linux system you can get a random number out of /dev/random or /dev/urandom. Be carefull /dev/random will block if there are not enough random numbers available. If you need speed over randomness use /dev/urandom.

These "files" will be filled with random numbers generated by the operating system. It depends on the implementation of /dev/random on your system if you get true or pseudo random numbers. True random numbers are generated with help form noise gathered from device drivers like mouse, hard drive, network.

You can get random numbers from the file with dd

This is actually on the main page of nltk.org:

>>> import nltk
>>> sentence = """At eight o'clock on Thursday morning
... Arthur didn't feel very good."""
>>> tokens = nltk.word_tokenize(sentence)
>>> tokens
['At', 'eight', "o'clock", 'on', 'Thursday', 'morning',
'Arthur', 'did', "n't", 'feel', 'very', 'good', '.']

Indeed, you don't need to drop a @local_variable.

But if you use #local_table, it can be done, e.g. it's convenient to be able to re-execute a query several times.

SELECT *
INTO #recent_records
FROM dbo.my_table t
WHERE t.CreatedOn > '2021-01-01'
;

SELECT *
FROM #recent_records
;

/*
  can DROP here, otherwise will fail with the following error
  on re-execution in the same window (I use SSMS DB client):

  Msg 2714, Level ..., State ..., Line ...
  There is already an object named '#recent_records' in the database.
*/
DROP TABLE #recent_records
;

You can also put your SELECT statement in a TRANSACTION to be able to re-execute without an explicit DROP:

BEGIN TRANSACTION

  SELECT *
  INTO #recent_records
  FROM dbo.my_table t
  WHERE t.CreatedOn > '2021-01-01'
  ;

  SELECT *
  FROM #recent_records
  ;

ROLLBACK

Here is the implementation to delete all the substrings from the given string

public static String deleteAll(String str, String pattern)
{
    for(int index = isSubstring(str, pattern); index != -1; index = isSubstring(str, pattern))
        str = deleteSubstring(str, pattern, index);

    return str;
}

public static String deleteSubstring(String str, String pattern, int index)
{
    int start_index = index;
    int end_index = start_index + pattern.length() - 1;
    int dest_index = 0;
    char[] result = new char[str.length()];


    for(int i = 0; i< str.length() - 1; i++)
        if(i < start_index || i > end_index)
            result[dest_index++] = str.charAt(i);

    return new String(result, 0, dest_index + 1);
}

The implementation of isSubstring() method is here

unfortunately, with "mvim -v", ALT plus arrow windows still does not work. I have not found any way to enable it :-(

If you want to want to treat 1,2 and 2,1 as the same pair, then this will give you the unique list on MS-SQL:

SELECT DISTINCT 
    CASE WHEN a > b THEN a ELSE b END as a,
    CASE WHEN a > b THEN b ELSE a END as b
FROM pairs

Inspired by @meszias answer above

This should work.

SELECT a.[CUSTOMER ID], a.[NAME], SUM(b.[AMOUNT]) AS [TOTAL AMOUNT]
FROM RES_DATA a INNER JOIN INV_DATA b
ON a.[CUSTOMER ID]=b.[CUSTOMER ID]
GROUP BY a.[CUSTOMER ID], a.[NAME]

I tested it with SQL Fiddle against SQL Server 2008: http://sqlfiddle.com/#!3/1cad5/1

Basically what's happening here is that, because of the join, you are getting the same row on the "left" (i.e. from the RES_DATA table) for every row on the "right" (i.e. the INV_DATA table) that has the same [CUSTOMER ID] value. When you group by just the columns on the left side, and then do a sum of just the [AMOUNT] column from the right side, it keeps the one row intact from the left side, and sums up the matching values from the right side.

Rather than preg_replace, you could always use PHP's filter functions using the filter_var() function with FILTER_SANITIZE_STRING.

onclick="this.focus();this.select()"

You can Change it from:

Menu Settings -> Style Configurator

See on screenshot:

Concept explained

Are you trying do a cross-domain AJAX call? Meaning, your service is not hosted in your same web application path? Your web-service must support method injection in order to do JSONP.

Your code seems fine and it should work if your web services and your web application hosted in the same domain.

When you do a $.ajax with dataType: 'jsonp' meaning that jQuery is actually adding a new parameter to the query URL.

For instance, if your URL is http://10.211.2.219:8080/SampleWebService/sample.do then jQuery will add ?callback={some_random_dynamically_generated_method}.

This method is more kind of a proxy actually attached in window object. This is nothing specific but does look something like this:

window.some_random_dynamically_generated_method = function(actualJsonpData) {
    //here actually has reference to the success function mentioned with $.ajax
    //so it just calls the success method like this: 
    successCallback(actualJsonData);
}

Summary

Your client code seems just fine. However, you have to modify your server-code to wrap your JSON data with a function name that passed with query string. i.e.

If you have reqested with query string

?callback=my_callback_method

then, your server must response data wrapped like this:

my_callback_method({your json serialized data});

Python 3.9 adds the zoneinfo module so now only the standard library is needed!

from zoneinfo import ZoneInfo
from datetime import datetime
unaware = datetime(2020, 10, 31, 12)

Attach a timezone:

>>> unaware.replace(tzinfo=ZoneInfo('Asia/Tokyo'))
datetime.datetime(2020, 10, 31, 12, 0, tzinfo=zoneinfo.ZoneInfo(key='Asia/Tokyo'))
>>> str(_)
'2020-10-31 12:00:00+09:00'

Attach the system's local timezone:

>>> unaware.replace(tzinfo=ZoneInfo('localtime'))
datetime.datetime(2020, 10, 31, 12, 0, tzinfo=zoneinfo.ZoneInfo(key='localtime'))
>>> str(_)
'2020-10-31 12:00:00+01:00'

Subsequently it is properly converted to other timezones:

>>> unaware.replace(tzinfo=ZoneInfo('localtime')).astimezone(ZoneInfo('Asia/Tokyo'))
datetime.datetime(2020, 10, 31, 20, 0, tzinfo=backports.zoneinfo.ZoneInfo(key='Asia/Tokyo'))
>>> str(_)
'2020-10-31 20:00:00+09:00'

Wikipedia list of available time zones

Windows has no system time zone database, so here an extra package is needed:

pip install tzdata  

There is a backport to allow use of zoneinfo in Python 3.6 to 3.8:

pip install backports.zoneinfo

Then:

from backports.zoneinfo import ZoneInfo

Just add the name of the table between DELETE and FROM from where you want to delete records, because we have to specify the table to delete. Also remove the ORDER BY clause because there is nothing to order while deleting records.

So your final query should be like this:

    DELETE WorkRecord2 
      FROM WorkRecord2 
INNER JOIN Employee 
        ON EmployeeRun=EmployeeNo
     WHERE Company = '1' 
       AND Date = '2013-05-06';

First of all, you do not have to develop any form yourself : phpMyAdmin, depending on its configuration (i.e. config.inc.php) will display an identification form, asking for a login and password.

To get that form, you should not use :

$cfg['Servers'][$i]['auth_type'] = 'config';

But you should use :

$cfg['Servers'][$i]['auth_type'] = 'cookie';

(At least, that's what I have on a server which prompts for login/password, using a form)

For more informations, you can take a look at the documentation :

• Using authentication modes
• Configuration, which states (quoting) :

'config' authentication ($auth_type = 'config') is the plain old way: username and password are stored in config.inc.php.

'cookie' authentication mode ($auth_type = 'cookie') as introduced in 2.2.3 allows you to log in as any valid MySQL user with the help of cookies.
Username and password are stored in cookies during the session and password is deleted when it ends.

it would be great if somebody told to put gif into any folder instead of assets folder

I was facing the same problem and the second method proposed in the accepted answer, as noted in the comments, can be problematic when dealing with foreign keys.

My workaround is to export the database to a sql file making sure that the INSERT statements include column names. I do it using DB Browser for SQLite which has an handy feature for that. After that you just have to edit the create table statement and insert the new column where you want it and recreate the db.

In *nix like systems is just something along the lines of

cat db.sql | sqlite3 database.db

I don't know how feasible this is with very big databases, but it worked in my case.

You can also use awk to make it a little bit prettier:

git rev-list --left-right --count  origin/develop...feature-branch | awk '{print "Behind "$1" - Ahead "$2""}'

You can even make an alias that always fetches origin first and then compares the branches

commit-diff = !"git fetch &> /dev/null && git rev-list --left-right --count"

Once a mate of mine and I redefined return to find a tricky stack corruption bug.

Something like:

#define return DoSomeStackCheckStuff, return

I think

from io import open

should do.

No packages needed:

String paddedString = i < 100 ? i < 10 ? "00" + i : "0" + i : "" + i;

This will pad the string to three characters, and it is easy to add a part more for four or five. I know this is not the perfect solution in any way (especially if you want a large padded string), but I like it.

->

calls/sets object variables. Ex:

$obj = new StdClass;
$obj->foo = 'bar';
var_dump($obj);

=> Sets key/value pairs for arrays. Ex:

$array = array(
    'foo' => 'bar'
);
var_dump($array);

<xs:element name="price" type="decimal">
<xs:attribute name="currency" type="xs:string" value="(euros|pounds|dollars)" /> 
</element> 

This would eliminate the need for enumeration completely. You could change type to double if required.

The best way is to user sass-loader. It is available as npm package. It resolves all path related issues and make it super easy.

I think this is the easiest way for multy selection/update/insert/delete. You can run as many update/insert/delete as u want after select (you have to make a select first(a dummy if needed)) with executeUpdate(str) (just use new int(count1,count2,...)) and if u need a new selection close 'statement' and 'connection' and make new for next select. Like example:

String str1 = "select * from users";
String str9 = "INSERT INTO `port`(device_id, potition, port_type, di_p_pt) VALUE ('"+value1+"', '"+value2+"', '"+value3+"', '"+value4+"')";
String str2 = "Select port_id from port where device_id = '"+value1+"' and potition = '"+value2+"' and port_type = '"+value3+"' ";
try{  
    Class.forName("com.mysql.jdbc.Driver").newInstance();
    theConnection=(Connection) DriverManager.getConnection(dbURL,dbuser,dbpassword);  
    theStatement = theConnection.prepareStatement(str1);
    ResultSet theResult = theStatement.executeQuery();
    int count8 = theStatement.executeUpdate(str9);
    theStatement.close();
    theConnection.close();
    theConnection=DriverManager.getConnection(dbURL,dbuser,dbpassword);
    theStatement = theConnection.prepareStatement(str2);
    theResult = theStatement.executeQuery();

    ArrayList<Port> portList = new ArrayList<Port>();
    while (theResult.next()) {
        Port port = new Port();
        port.setPort_id(theResult.getInt("port_id"));

        portList.add(port);
    }

I hope it helps

You can make your code look better like this:

public void someMethod(){
    List<Integer> numbers = new ArrayList<Integer>();
    numbers.addAll(db.findNumbers());
    ...
    System.out.println("Result is " + sumOfNumbers(numbers));
}

private int sumOfNumbers(List<Integer> numbers){
    int sum = 0;
    for (Integer i : numbers){
      sum += i;
    }
    return sum;
}

You can also use colorworks.

Usage:

var cw = require('colorworks').create();
console.info(cw.compile('[[red|Red message with a [[yellow|yellow]] word.]]'));

To make life easier, you can also make a function with it.

function say(msg) {
  console.info(cw.compile(msg));
}

Now you can do:

say(`[[yellow|Time spent: [[green|${time}]]ms.]]`);

Be very careful with the Excel MOD(a,b) function and the VBA a Mod b operator. Excel returns a floating point result and VBA an integer.

In Excel =Mod(90.123,90) returns 0.123000000000005 instead of 0.123 In VBA 90.123 Mod 90 returns 0

They are certainly not equivalent!

Equivalent are: In Excel: =Round(Mod(90.123,90),3) returning 0.123 and In VBA: ((90.123 * 1000) Mod 90000)/1000 returning also 0.123

Make sure to check dynamic web app in "other section" i.e File>New>Other>Web or type in "dynamic web app" in your wizard filter. If dynamic web app is not there then follow following steps:

1. On Eclipse Menu Select HELP > INSTALL NEW SOFTWARE
2. In work with test box simply type in your eclipse version, which is oxygen in my case
3. Once you type in yur version something like this "Oxygen - http://download.eclipse.org/releases/oxygen"will be recommended to you in drop down
4. If you do not get any recommendation then simply copy " http://download.eclipse.org/releases/your-version" and paste it. Make sure to edit your-version.
5. After you Enter the address and press enter bunch of new softwares will be listed just ubderneath work with text box.
6. Scroll, find and Expand WEB, XML, Java EE .... tab
7. Select only these three options: Eclipse Java EE Developer Tools, Eclipse Java Web Developer Tools,Eclipse Web Developer Tools
8. Next, next and finish!

Try building your project from the Powershell command line:

dotnet build

Then you can see any errors in the command line output even if Visual Studio is playing hide and seek with build error messages.

always Until you fully understand the differences and implications of using the == and === operators, use the === operator since it will save you from obscure (non-obvious) bugs and WTFs. The "regular" == operator can have very unexpected results due to the type-coercion internally, so using === is always the recommended approach.

For insight into this, and other "good vs. bad" parts of Javascript read up on Mr. Douglas Crockford and his work. There's a great Google Tech Talk where he summarizes lots of good info: http://www.youtube.com/watch?v=hQVTIJBZook

Update:

The You Don't Know JS series by Kyle Simpson is excellent (and free to read online). The series goes into the commonly misunderstood areas of the language and explains the "bad parts" that Crockford suggests you avoid. By understanding them you can make proper use of them and avoid the pitfalls.

The "Up & Going" book includes a section on Equality, with this specific summary of when to use the loose (==) vs strict (===) operators:

To boil down a whole lot of details to a few simple takeaways, and help you know whether to use == or === in various situations, here are my simple rules:

• If either value (aka side) in a comparison could be the true or false value, avoid == and use ===.
• If either value in a comparison could be of these specific values (0, "", or [] -- empty array), avoid == and use ===.
• In all other cases, you're safe to use ==. Not only is it safe, but in many cases it simplifies your code in a way that improves readability.

I still recommend Crockford's talk for developers who don't want to invest the time to really understand Javascript—it's good advice for a developer who only occasionally works in Javascript.

If you move from iframes, you may get lost in your page, best way to execute some jquery without issue (with selenimum/python/gecko):

# 1) Get back to the main body page
driver.switch_to.default_content()

# 2) Download jquery lib file to your current folder manually & set path here
with open('./_lib/jquery-3.3.1.min.js', 'r') as jquery_js: 
    # 3) Read the jquery from a file
    jquery = jquery_js.read() 
    # 4) Load jquery lib
    driver.execute_script(jquery)
    # 5) Execute your command 
    driver.execute_script('$("#myId").click()')

Here’s some PHP and JavaScript demonstration code that shows a simple way to create indexed fields on a form (fields that have the same name) and then process them in both JavaScript and PHP. The fields must have both "ID" names and "NAME" names. Javascript uses the ID and PHP uses the NAME.

<?php
// How to use same field name multiple times on form
// Process these fields in Javascript and PHP
// Must use "ID" in Javascript and "NAME" in PHP 
echo "<HTML>";
echo "<HEAD>";
?>
<script type="text/javascript">
function TestForm(form) {
// Loop through the HTML form field (TheId) that is returned as an array. 
// The form field has multiple (n) occurrences on the form, each which has the same name.
// This results in the return of an array of elements indexed from 0 to n-1.
// Use ID  in Javascript
var i = 0;
document.write("<P>Javascript responding to your button click:</P>");
for (i=0; i < form.TheId.length; i++) {
  document.write(form.TheId[i].value);
  document.write("<br>");
}  
}
</script>
<?php
echo "</HEAD>";
echo "<BODY>";
$DQ = '"';  # Constant for building string with double quotes in it.

if (isset($_POST["MyButton"])) {
  $TheNameArray = $_POST["TheName"];  # Use NAME in PHP
  echo "<P>Here are the names you submitted to server:</P>";
  for ($i = 0; $i <3; $i++) {   
    echo $TheNameArray[$i] . "<BR>";
  } 
}
echo "<P>Enter names and submit to server or Javascript</P>";
echo "<FORM NAME=TstForm METHOD=POST ACTION=" ;
echo $DQ . "TestArrayFormToJavascript2.php" . $DQ . "OnReset=" . $DQ . "return allowreset(this)" . $DQ . ">";
echo "<FORM>";
echo "<INPUT ID = TheId NAME=" . $DQ . "TheName[]" . $DQ . " VALUE=" . $DQ . "" . $DQ . ">";
echo "<INPUT ID = TheId NAME=" . $DQ . "TheName[]" . $DQ . " VALUE=" . $DQ . "" . $DQ . ">";
echo "<INPUT ID = TheId NAME=" . $DQ . "TheName[]" . $DQ . " VALUE=" . $DQ . "" . $DQ . ">";
echo "<P><INPUT TYPE=submit NAME=MyButton VALUE=" . $DQ . "Submit to server"    . $DQ . "></P>";
echo "<P><BUTTON onclick=" . $DQ . "TestForm(this.form)" . $DQ . ">Submit to Javascript</BUTTON></P>"; 
echo "</FORM>";
echo "</BODY>";
echo "</HTML>";

At the beginning of your loading script, just make your

visible through css [display:block;] and make the rest of the page invisible through css[display:none;].

Once the loading is done, just make the loading invisible and the page visible again with the same technique. You can use the document.getElementById() to select the divs you want to change the display.

Edit: Here's what it would sort of look like. When the body finishes loading, it will call the javascript function that will change the display values of the different elements. By default, your style would be to have the page not visible the loading visible.

<head>
    <style>
        #page{
            display: none;
        }
        #loading{
            display: block;
        }
    </style>
    <script>
        function myFunction()
        {
            document.getElementById("page").style.display = "block";
            document.getElementById("loading").style.display = "none";
        }
    </script>
</head>

<body onload="myFunction()">
    <div id="page">

    </div>
    <div id="loading">

    </div>
</body>

There are probably embedded tabs (CHAR(9)) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:

DECLARE @var NVARCHAR(255), @i INT;

SET @i = 1;

SELECT @var = AccountType FROM dbo.Account
  WHERE AccountNumber = 200
  AND AccountType LIKE '%Daily%';

CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));

WHILE @i <= LEN(@var)
BEGIN
  INSERT #x 
    SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));

  SET @i = @i + 1;
END

SELECT i,c,a FROM #x ORDER BY i;

You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.

The documentation states several ways to do this.

If you want to replace the default ObjectMapper completely, define a @Bean of that type and mark it as @Primary.

Defining a @Bean of type Jackson2ObjectMapperBuilder will allow you to customize both default ObjectMapper and XmlMapper (used in MappingJackson2HttpMessageConverter and MappingJackson2XmlHttpMessageConverter respectively).

Your only option is to somehow clone the object.

See this stackoverflow question on how you can achieve this.

For simple JSON objects, the simplest way would be:

var newObject = JSON.parse(JSON.stringify(oldObject));

if you use jQuery, you can use:

// Shallow copy
var newObject = jQuery.extend({}, oldObject);

// Deep copy
var newObject = jQuery.extend(true, {}, oldObject);

UPDATE 2017: I should mention, since this is a popular answer, that there are now better ways to achieve this using newer versions of javascript:

In ES6 or TypeScript (2.1+):

var shallowCopy = { ...oldObject };

var shallowCopyWithExtraProp = { ...oldObject, extraProp: "abc" };

Note that if extraProp is also a property on oldObject, its value will not be used because the extraProp : "abc" is specified later in the expression, which essentially overrides it. Of course, oldObject will not be modified.

You're looking for the JavaScriptSerializer class, which is used internally by JsonResult:

string json = new JavaScriptSerializer().Serialize(jsonResult.Data);

If you want to use managed code: This will capture any window via the ProcessId.

I used the following to make the window active.

Microsoft.VisualBasic.Interaction.AppActivate(ProcessId);
Threading.Thread.Sleep(20);

I used the print screen to capture a window.

SendKeys.SendWait("%{PRTSC}");
Threading.Thread.Sleep(40);
IDataObject objData = Clipboard.GetDataObject();

Have you tried using Firebug to inspect the rendered HTML, and to see exactly what css is being applied to the various elements? That should pick up css errors like the ones mentioned above, and you can see what styles are being inherited and from where - it is an invaluable too in any css debugging.

You have a misplaced closing brace before the return statement.

I just finished my weekend project cached-webpgr.js which uses the localStorage / web storage to cache JavaScript files. This approach is very fast. My small test showed

• Loading jQuery from CDN: Chrome 268ms, FireFox: 200ms
• Loading jQuery from localStorage: Chrome 47ms, FireFox 14ms

The code to achieve that is tiny, you can check it out at my Github project https://github.com/webpgr/cached-webpgr.js

Here is a full example how to use it.

The complete library:

function _cacheScript(c,d,e){var a=new XMLHttpRequest;a.onreadystatechange=function(){4==a.readyState&&(200==a.status?localStorage.setItem(c,JSON.stringify({content:a.responseText,version:d})):console.warn("error loading "+e))};a.open("GET",e,!0);a.send()}function _loadScript(c,d,e,a){var b=document.createElement("script");b.readyState?b.onreadystatechange=function(){if("loaded"==b.readyState||"complete"==b.readyState)b.onreadystatechange=null,_cacheScript(d,e,c),a&&a()}:b.onload=function(){_cacheScript(d,e,c);a&&a()};b.setAttribute("src",c);document.getElementsByTagName("head")[0].appendChild(b)}function _injectScript(c,d,e,a){var b=document.createElement("script");b.type="text/javascript";c=JSON.parse(c);var f=document.createTextNode(c.content);b.appendChild(f);document.getElementsByTagName("head")[0].appendChild(b);c.version!=e&&localStorage.removeItem(d);a&&a()}function requireScript(c,d,e,a){var b=localStorage.getItem(c);null==b?_loadScript(e,c,d,a):_injectScript(b,c,d,a)};

Calling the library

requireScript('jquery', '1.11.2', 'http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js', function(){
    requireScript('examplejs', '0.0.3', 'example.js');
});

The --no-ff flag causes the merge to always create a new commit object, even if the merge could be performed with a fast-forward. This avoids losing information about the historical existence of a feature branch and groups together all commits that together added the feature

This ensures that resolution occurs from the global namespace, instead of starting at the namespace you're currently in. For instance, if you had two different classes called Configuration as such:

class Configuration; // class 1, in global namespace
namespace MyApp
{
    class Configuration; // class 2, different from class 1
    function blah()
    {
        // resolves to MyApp::Configuration, class 2
        Configuration::doStuff(...) 
        // resolves to top-level Configuration, class 1
        ::Configuration::doStuff(...)
    }
}

Basically, it allows you to traverse up to the global namespace since your name might get clobbered by a new definition inside another namespace, in this case MyApp.

set.seed is a base function that it is able to generate (every time you want) together other functions (rnorm, runif, sample) the same random value.

Google's (bad) approach, from HN thread. Store RLE-style counts.

Your initial data structure is '99999999:0' (all zeros, haven't seen any numbers) and then lets say you see the number 3,866,344 so your data structure becomes '3866343:0,1:1,96133654:0' as you can see the numbers will always alternate between number of zero bits and number of '1' bits so you can just assume the odd numbers represent 0 bits and the even numbers 1 bits. This becomes (3866343,1,96133654)

Their problem doesn't seem to cover duplicates, but let's say they use "0:1" for duplicates.

Big problem #1: insertions for 1M integers would take ages.

Big problem #2: like all plain delta encoding solutions, some distributions can't be covered this way. For example, 1m integers with distances 0:99 (e.g. +99 each one). Now think the same but with random distance in the range of 0:99. (Note: 99999999/1000000 = 99.99)

Google's approach is both unworthy (slow) and incorrect. But to their defense, their problem might have been slightly different.

Running rails g migration AddUserRefToSponsors user:references will generate the following migration:

Put a checkmark on Microsoft.VisualBasic.

Hit OK.

That link is for Visual Studio 2013, you can use the "Other versions" dropdown for different versions of visual studio.

In all cases you need to add a reference to the .NET assembly "Microsoft.VisualBasic".

At the top of your c# file you neeed:

using Microsoft.VisualBasic;

Then you can look at writing the code.

The code would be something like:

   private void btnOK_Click(object sender, EventArgs e)
   {
      if ( Information.IsNumeric(startingbudget) )
      {
         MessageBox.Show("This is a number.");
      }
   }

Print all args without the filename:

for i in range(1, len(sys.argv)):
print(sys.argv[i])

I tried closing a modal window with a bootstrap CSS loaded. The close () method does not really close the modal window. So I added the display style to "none".

    function closeDialog() {
        let d = document.getElementById('d')
        d.style.display = "none"
        d.close()
    }

The HTML code includes a button into the dialog window.

<input type="submit" value="Confirm" onclick="closeDialog()"/>

public static void writeStringAsFile(final String fileContents, String fileName) {
    Context context = App.instance.getApplicationContext();
    try {
        FileWriter out = new FileWriter(new File(context.getFilesDir(), fileName));
        out.write(fileContents);
        out.close();
    } catch (IOException e) {
        Logger.logError(TAG, e);
    }
}

public static String readFileAsString(String fileName) {
    Context context = App.instance.getApplicationContext();
    StringBuilder stringBuilder = new StringBuilder();
    String line;
    BufferedReader in = null;

    try {
        in = new BufferedReader(new FileReader(new File(context.getFilesDir(), fileName)));
        while ((line = in.readLine()) != null) stringBuilder.append(line);

    } catch (FileNotFoundException e) {
        Logger.logError(TAG, e);
    } catch (IOException e) {
        Logger.logError(TAG, e);
    } 

    return stringBuilder.toString();
}

I used AndExplorer for this purpose and my solution is popup a dialog and then redirect on the market to install the misssing application:

My startCreation is trying to call external file/directory picker. If it is missing call show installResultMessage function.

private void startCreation(){
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_PICK);
    Uri startDir = Uri.fromFile(new File("/sdcard"));

    intent.setDataAndType(startDir,
            "vnd.android.cursor.dir/lysesoft.andexplorer.file");
    intent.putExtra("browser_filter_extension_whitelist", "*.csv");
    intent.putExtra("explorer_title", getText(R.string.andex_file_selection_title));
    intent.putExtra("browser_title_background_color",
            getText(R.string.browser_title_background_color));
    intent.putExtra("browser_title_foreground_color",
            getText(R.string.browser_title_foreground_color));
    intent.putExtra("browser_list_background_color",
            getText(R.string.browser_list_background_color));
    intent.putExtra("browser_list_fontscale", "120%");
    intent.putExtra("browser_list_layout", "2");

    try{
         ApplicationInfo info = getPackageManager()
                                 .getApplicationInfo("lysesoft.andexplorer", 0 );

            startActivityForResult(intent, PICK_REQUEST_CODE);
    } catch( PackageManager.NameNotFoundException e ){
        showInstallResultMessage(R.string.error_install_andexplorer);
    } catch (Exception e) {
        Log.w(TAG, e.getMessage());
    }
}

This methos is just pick up a dialog and if user wants install the external application from market

private void showInstallResultMessage(int msg_id) {
    AlertDialog dialog = new AlertDialog.Builder(this).create();
    dialog.setMessage(getText(msg_id));
    dialog.setButton(getText(R.string.button_ok),
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    finish();
                }
            });
    dialog.setButton2(getText(R.string.button_install),
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    Intent intent = new Intent(Intent.ACTION_VIEW);
                    intent.setData(Uri.parse("market://details?id=lysesoft.andexplorer"));
                    startActivity(intent);
                    finish();
                }
            });
    dialog.show();
}

you may try this one, used CONCAT

WHERE LastName LIKE Concat('%',@LastName,'%')

Try this:

"maingame": {
  "day1": {
    "text1": "Tag 1",
     "text2": "Heute startet unsere Rundreise \" Example text\". Jeden Tag wird ein neues Reiseziel angesteuert bis wir.</strong> "
  }
}

(just one backslash (\) in front of quotes).

Change your code like this. You forget about the value inside option. Before you assign the ng-model. It must have a value. Only then it doesn't get the undefined value.

<div ng-app="MyApp1">
<div ng-controller="MyController">
    <input type="text" ng-model="feed.name" placeholder="Name" />
     <select ng-model="feed">
        <option ng-repeat="template in configs" value="template.value">{{template.name}}    
 </option>
    </select>
    </div>
 </div>

JS

 var MyApp=angular.module('MyApp1',[])
 MyApp.controller('MyController',function($scope) {  
      $scope.feed = 'config1';      
      $scope.configs = [
         {'name': 'Config 1', 'value': 'config1'},
         {'name': 'Config 2', 'value': 'config2'},
         {'name': 'Config 3', 'value': 'config3'}
      ];
 });

You can do it like this:

SELECT * FROM (SELECT your_table.your_field, versions_starttime
               FROM your_table
               VERSIONS BETWEEN TIMESTAMP MINVALUE AND MAXVALUE)
WHERE ROWNUM = 1;

Or:

SELECT your_field,ora_rowscn,scn_to_timestamp(ora_rowscn) from your_table WHERE ROWNUM = 1;

1) Upgrade using windows update or using "media creation tool" http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install

• if you are using "media creation tool" select "Upgrade this PC now"

When Windows 10 installed check that it is activated.

2) Now as you have activated Windows 10 using "media creation tool" http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install select second option "Create installation media for another PC" here you can select Windows version and its language. Make sure that Windows version is also "Single Language"

3) Boot from you device, USB in my case and install clean Windows in English or any other language you selected.

For RHEL/CentOS, run "python --version" command to find out Python version. E.g. below:

$ python --version 
  Python 2.7.12

Now run "sudo yum search lxml" to find out python*-lxml package.

$ sudo yum search lxml
Failed to set locale, defaulting to C
Loaded plugins: priorities, update-motd, upgrade-helper
1014 packages excluded due to repository priority protections
============================================================================================================= N/S matched: lxml =============================================================================================================

python27-lxml-docs.noarch : Documentation for python-lxml
python26-lxml.x86_64 : ElementTree-like Python bindings for libxml2 and libxslt
python27-lxml.x86_64 : ElementTree-like Python bindings for libxml2 and libxslt

Now you can choose package as per your Python version and run command like below:

$ sudo yum install python27-lxml.x86_64

In my case "EditorConfig for VS Code" extention is overriding VSCode settings. If you have it installed, then check .editorconfig file in the root folder of the project.

Here is an example config. The "indent_size" sets the number of spaces for a tab.

# editorconfig.org
root = true

[*]
indent_style = space
indent_size = 4
end_of_line = lf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true

[*.md]
trim_trailing_whitespace = false

Since MATLAB seamlessly integrates with Java, you can use Jython to write your script and call that from MATLAB (you may have to add a thin pure JKava wrapper to actually call the Jython code). I never tried it, but I can't see why it won't work.

String allocates dynamic memory size in the heap of your RAM. But string address is stored in stack that occupies 4 bytes of memory.

A today extension would be the most fitting solution.

Also you could do something on the lock screen with local notifications queued up to fire at regular intervals showing the latest countdown value.

    import torch.nn as nn        

    # a simple network
    rand_net = nn.Sequential(nn.Linear(in_features, h_size),
                             nn.BatchNorm1d(h_size),
                             nn.ReLU(),
                             nn.Linear(h_size, h_size),
                             nn.BatchNorm1d(h_size),
                             nn.ReLU(),
                             nn.Linear(h_size, 1),
                             nn.ReLU())

    # initialization function, first checks the module type,
    # then applies the desired changes to the weights
    def init_normal(m):
        if type(m) == nn.Linear:
            nn.init.uniform_(m.weight)

    # use the modules apply function to recursively apply the initialization
    rand_net.apply(init_normal)

First you convert VARCHAR to DATE and then back to CHAR. I do this almost every day and never found any better way.

select TO_CHAR(TO_DATE(DOJ,'MM/DD/YYYY'), 'MM/DD/YYYY') from EmpTable

NOW() is the replacement of Oracle Sysdate in Postgres.

Try "Select now()", it will give you the system timestamp.

2017 Update - since WooCommerce 3:

global $product;
$id = $product->get_id();

Woocommerce doesn't like you accessing those variables directly. This will get rid of any warnings from woocommerce if your wp_debug is true.

The best way to get good control over the colorbar position is to give it its own axis. Like so:

# What I imagine your plotting looks like so far
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax1.plot(your_data)

# Now adding the colorbar
cbaxes = fig.add_axes([0.8, 0.1, 0.03, 0.8]) 
cb = plt.colorbar(ax1, cax = cbaxes)  

The numbers in the square brackets of add_axes refer to [left, bottom, width, height], where the coordinates are just fractions that go from 0 to 1 of the plotting area.

Hi I face the same problem today. After reading "Spentak"'s answer i tried to make code signing of my target to set to iOSDeveloper, and still did not work. But after i changing "Provisioning Profile" to "Automatic", the project got built and ran without any code signing errors.

In order to avoid path problem, you can simply try this, just keep background image in images folder and add this code

<Grid>
  <Grid.Background>
    <ImageBrush Stretch="Fill" ImageSource="..\Images\background.jpg"
                AlignmentY="Top" AlignmentX="Center"/>
  </Grid.Background>
</Grid>

You may need to repair your mdf file first using some tools. There are lot of tool available in the market. There is tool called SQL Database Recovery Tool Repairs which is very useful to repair the mdf files.

The issue might me because of corrupted transaction logs, you may use tool SQL Database Recovery Tool Repairs to repair your corrupted mdf file.

I had exactly the same problem and what resolved it was to remove the closure:

$(function(){
    var app = angular.module("myApp", []); 
    app.controller('myController', function(){
        ...
    });
});

becomes:

var app = angular.module("myApp", []); 
app.controller('myController', function(){
    ...
});

Use nsIJSON if this is for a FF extension:

var req = new XMLHttpRequest;
req.overrideMimeType("application/json");
req.open('GET', BITLY_CREATE_API + encodeURIComponent(url) + BITLY_API_LOGIN, true);
var target = this;
req.onload = function() {target.parseJSON(req, url)};
req.send(null);

parseJSON: function(req, url) {
if (req.status == 200) {
  var jsonResponse = Components.classes["@mozilla.org/dom/json;1"]
      .createInstance(Components.interfaces.nsIJSON.decode(req.responseText);
  var bitlyUrl = jsonResponse.results[url].shortUrl;
}

For a webpage, just use JSON.parse instead of Components.classes["@mozilla.org/dom/json;1"].createInstance(Components.interfaces.nsIJSON.decode

The regex you need is /(.)\1{9,}/.

Test:

#!perl
use warnings;
use strict;
my $regex = qr/(.)\1{9,}/;
print "NO" if "abcdefghijklmno" =~ $regex;
print "YES" if "------------------------" =~ $regex;
print "YES" if "========================" =~ $regex;

Here the \1 is called a backreference. It references what is captured by the dot . between the brackets (.) and then the {9,} asks for nine or more of the same character. Thus this matches ten or more of any single character.

Although the above test script is in Perl, this is very standard regex syntax and should work in any language. In some variants you might need to use more backslashes, e.g. Emacs would make you write \(.\)\1\{9,\} here.

If a whole string should consist of 9 or more identical characters, add anchors around the pattern:

my $regex = qr/^(.)\1{9,}$/;

$SQL_Part="("
$i=0;
while ($i<length($cat)-1)
{
   $SQL_Part+=$cat[i]+",";
}
$SQL_Part=$SQL_Part+$cat[$i+1]+")"

$SQL="SELECT * FROM products WHERE catid IN "+$SQL_Part;

It's more generic and will fit for any array!!

Basically, ajax request as well as synchronous request sends your document cookies automatically. So, you need to set your cookie to document, not to request. However, your request is cross-domain, and things became more complicated. Basing on this answer, additionally to set document cookie, you should allow its sending to cross-domain environment:

type: "GET",    
url: "http://example.com",
cache: false,
// NO setCookies option available, set cookie to document
//setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",
crossDomain: true,
dataType: 'json',
xhrFields: {
    withCredentials: true
},
success: function (data) {
    alert(data);
});

step1:
class CNAME:
   ...
   def as_dict(self):
       return {item.name: getattr(self, item.name) for item in self.__table__.columns}

step2:
list = []
for data in session.query(CNAME).all():
    list.append(data.as_dict())

step3:
return jsonify(list)

resolve the url like this href="<%=ResolveUrl("~/favicon.ico")%>"

Just to add my own experiences with this: my company's proxy is http://webproxy.intra.companyname.com:3128. For maven to work via this proxy, the settings have to be exactly like this

<settings>
  <proxies>
    <proxy>
      <id>default</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>webproxy.intra.companyname.com</host>
      <port>3128</port>
    </proxy>
  </proxies>
</settings>

Unlike some other proxy-configuration files, the protocol here describes how to connect to the proxy server, not which kinds of protocol should be proxied. The http part of the target has to be split off from the hostname, else it won't work.

If you want to use jQuery File Download , please note this for IE. You need to reset the response or it will not download

    //The IE will only work if you reset response
    getServletResponse().reset();
    //The jquery.fileDownload needs a cookie be set
    getServletResponse().setHeader("Set-Cookie", "fileDownload=true; path=/");
    //Do the reset of your action create InputStream and return

Your action can implement ServletResponseAware to access getServletResponse()

Use queue.rear+1 to get the length of the queue

As of PowerShell version 3.0, the Get-Content cmdlet has a -Tail parameter that should help. See the technet library online help for Get-Content.

Excel can display a Date type in a similar manner to a DateTime. Right click on the affected cell, select Format Cells, then under Category select Date and under Type select the type that looks something like this:

3/14/01 1:30 PM

That should do what you requested. I tested sorting on some sample data with this format and it seemed to work fine.

instead of

$('html, body').animate({scrollTop:xxx}, 'slow');

use

$('html, body').animate({scrollTop:$('#div_id').position().top}, 'slow');

this will return the absolute top position of whatever element you select as #div_id

PID is the process ID - not the port number. You need to look for an entry with ":8080" at the end of the address/port part (the second column). Then you can look at the PID and use Task Manager to work out which process is involved... or run netstat -abn which will show the process names (but must be run under an administrator account).

Having said that, I would expect the find "8080" to find it...

Another thing to do is just visit http://localhost:8080 - on that port, chances are it's a web server of some description.

Place the following in your jQuery mouseover event handler:

$(this).css('color', 'red');

To set both color and size at the same time:

$(this).css({ 'color': 'red', 'font-size': '150%' });

You can set any CSS attribute using the .css() jQuery function.
