Symfony is smart and knows how to make the find() by itself :

public function deleteGuestAction(Guest $guest)
{
    if (!$guest) {
        throw $this->createNotFoundException('No guest found');
    }

    $em = $this->getDoctrine()->getEntityManager();
    $em->remove($guest);
    $em->flush();

    return $this->redirect($this->generateUrl('GuestBundle:Page:viewGuests.html.twig'));
}

To send the id in your controller, use {{ path('your_route', {'id': guest.id}) }}

Lambda expression can be passed as a argument.To pass a lambda expression as an argument the type of the parameter (which receives the lambda expression as an argument) must be of functional interface type.

If there is a functional interface -

interface IMyFunc {
   boolean test(int num);
}

And there is a filter method which adds the int in the list only if it is greater than 5. Note here that filter method has funtional interface IMyFunc as one of the parameter. In that case lambda expression can be passed as an argument for the method parameter.

public class LambdaDemo {
    public static List<Integer> filter(IMyFunc testNum, List<Integer> listItems) {
        List<Integer> result = new ArrayList<Integer>();
        for(Integer item: listItems) {
            if(testNum.test(item)) {
                result.add(item);
            }
        }
        return result;
    }
    public static void main(String[] args) {
        List<Integer> myList = new ArrayList<Integer>();
        myList.add(1);
        myList.add(4);
        myList.add(6);
        myList.add(7);
        // calling filter method with a lambda expression
        // as one of the param
        Collection<Integer> values = filter(n -> n > 5, myList);

        System.out.println("Filtered values " + values);
    }
}

I found the answer to this problem here

Just do

mb_convert_encoding($data['name'], 'UTF-8', 'UTF-8');

With the other answers, the person reading the answer must be aware of a specific domain table such as vehicle or student. The table must be created and populated with data to test a solution.

Below is an example that uses SQL Server "Information_Schema.Columns" table. By using this solution, no tables need to be created or data added. This example creates a comma separated list of column names for all tables in the database.

SELECT
    Table_Name
    ,STUFF((
        SELECT ',' + Column_Name
        FROM INFORMATION_SCHEMA.Columns Columns
        WHERE Tables.Table_Name = Columns.Table_Name
        ORDER BY Column_Name
        FOR XML PATH ('')), 1, 1, ''
    )Columns
FROM INFORMATION_SCHEMA.Columns Tables
GROUP BY TABLE_NAME 

I don't see any answer with reference to CSS flex property, but it can be very useful too.

After building a few applications, some in Symfony-PHP, some .NET MVC, some ROR, i've found that the best way for me is to use Yeoman.io with the AngularJS generator.

That's the most popular and common structure and best maintained.

And most importantly, by keeping that structure, it helps you separate your client side code and to make it agnostic to the server-side technology (all kinds of different folder structures and different server-side templating engines).

That way you can easily duplicate and reuse yours and others code.

Here it is before grunt build: (but use the yeoman generator, don't just create it!)

/app
    /scripts
            /controllers
            /directives
            /services
            /filters
            app.js
    /views
    /styles
    /img
    /bower_components
    index.html
bower.json

And after grunt build (concat, uglify, rev, etc...):

    /scripts
        scripts.min.js (all JS concatenated, minified and grunt-rev)
        vendor.min.js  (all bower components concatenated, minified and grunt-rev)
    /views
    /styles
        mergedAndMinified.css  (grunt-cssmin)
    /images
    index.html  (grunt-htmlmin)

The error tells you that there is an error but you don´t catch it. This is how you can catch it:

getAllPosts().then(response => {
    console.log(response);
}).catch(e => {
    console.log(e);
});

You can also just put a console.log(reponse) at the beginning of your API callback function, there is definitely an error message from the Graph API in it.

More information: https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Global_Objects/Promise/catch

Or with async/await:

//some async function
try {
    let response = await getAllPosts();
} catch(e) {
    console.log(e);
}

You have to declare your functions before main()

(or declare the function prototypes before main())

As it is, the compiler sees my_print (my_string); in main() as a function declaration.

Move your functions above main() in the file, or put:

void my_print (char *);
void my_print2 (char *);

Above main() in the file.

When the branch is no remote branch you can push your local branch direct to the remote.

git checkout master
git push origin master

or when you have a dev branch

git checkout dev
git push origin dev

or when the remote branch exists

git branch dev -t origin/dev

There are some other posibilites to push a remote branch.

Instead of

Scanner in = new Scanner(System.in);
String question;
question = in.next();

Type in

Scanner in = new Scanner(System.in);
String question;
question = in.nextLine();

This should be able to take spaces as input.

Python 2.x:

print '-' * 3

Python 3.x:

print('-' * 3)

Using a static nested class rather than non-static one may save spaces in some cases. For example: implementing a Comparator inside a class, say Student.

public class Student {
  public static final Comparator<Student> BY_NAME = new ByName();
  private final String name;
  ...
  private static class ByName implements Comparator<Student> {
    public int compare() {...}
  }
}

Then the static ensures that the Student class has only one Comparator, rather than instantiate a new one every time a new student instance is created.

You are having this problem because you are attempting to console log app.address() before the connection has been made. You just have to be sure to console log after the connection is made, i.e. in a callback or after an event signaling that the connection has been made.

Fortunately, the 'listening' event is emitted by the server after the connection is made so just do this:

var express = require('express');
var http = require('http');

var app = express();
var server = http.createServer(app);

app.get('/', function(req, res) {
    res.send("Hello World!");
});

server.listen(3000, 'localhost');
server.on('listening', function() {
    console.log('Express server started on port %s at %s', server.address().port, server.address().address);
});

This works just fine in nodejs v0.6+ and Express v3.0+.

Two things.

1. Remove the parenthesis in setTimeout(startTimer(),startInterval);. Keeping the parentheses invokes the function immediately.

2. Your startTimer function will overwrite the page content with your use of document.write (without the above fix), and wipes out the script and HTML in the process.

I would do this as

if isnumeric(ubound(a)) = False then msgbox "a is empty!"

• A worker process runs as an executables file named W3wp.exe

• A Worker Process is user mode code whose role is to process requests, such as processing requests to return a static page.

• The worker process is controlled by the www service.

• worker processes also run application code, Such as ASP .NET applications and XML web Services.

• When Application pool receive the request, it simply pass the request to worker process (w3wp.exe) . The worker process“w3wp.exe” looks up the URL of the request in order to load the correct ISAPI extension. ISAPI extensions are the IIS way to handle requests for different resources. Once ASP.NET is installed, it installs its own ISAPI extension (aspnet_isapi.dll)and adds the mapping into IIS.

• When Worker process loads the aspnet_isapi.dll, it start an HTTPRuntime, which is the entry point of an application. HTTPRuntime is a class which calls the ProcessRequest method to start Processing.

For more detail refer URL http://aspnetnova.blogspot.in/2011/12/how-iis-process-for-aspnet-requests.html

You will not be able to do that. You can download apps again to the same userid account on different devices, but you cannot transfer those licenses to other userids.

There is no way to do this programatically - I don't think you can do that practically (except for trying to call customer support at the Play Store).

1. What is the difference between Git and GitHub?

   Linus Torvalds would kill you for this. Git is the name of the version manager program he wrote. GitHub is a website on which there are source code repositories manageable by Git. Thus, GitHub is completely unrelated to the original Git tool.

2. Is git saving every repository locally (in the user's machine) and in GitHub?

   If you commit changes, it stores locally. Then, if you push the commits, it also sotres them remotely.

3. Can you use Git without GitHub? If yes, what would be the benefit for using GitHub?

   You can, but I'm sure you don't want to manually set up a git server for yourself. Benefits of GitHub? Well, easy to use, lot of people know it so others may find your code and follow/fork it to make improvements as well.

4. How does Git compare to a backup system such as Time Machine?

   Git is specifically designed and optimized for source code.

5. Is this a manual process, in other words if you don't commit you wont have a new version of the changes made?

   Exactly.

6. If are not collaborating and you are already using a backup system why would you use Git?

   See #4.

I'd like to build upon some of the answers above and given elsewhere and suggest using absolute positioning along with the :before pseudo class. A lot of the examples above (and in similar questions) are utilizing custom HTML markup, including Font Awesome's method of handling. This goes against the original question, and isn't strictly necessary.

DEMO HERE

ul {
  list-style-type: none;
  padding-left: 20px;
}

li {
  position: relative;
  padding-left: 20px;
  margin-bottom: 10px
}

li:before {
  position: absolute;
  top: 0;
  left: 0;
  font-family: FontAwesome;
  content: "\f058";
  color: green;
}

That's basically it. You can get the ISO value for use in CSS content on the Font Awesome cheatsheet. Simply use the last 4 alphanumerics prefixed with a backslash. So [] becomes \f058

If you create a new Date object, by default it will be set to the current time:

import java.util.Date;
Date now = new Date();

You can use nested.

There are tow function one is openTab() and another is closeMobileMenue(), Firstly we call openTab() and call another function inside closeMobileMenue().

function openTab() {
    window.open('https://play.google.com/store/apps/details?id=com.drishya');
    closeMobileMenue()   //After open new tab, Nav Menue will close.  
}

onClick={openTab}

In case if you prefer grouping of this routes, you can do as :

Route::group(['namespace' => 'App\Http\Controllers\Api'], function () {
    Route::resource('user', 'UserController');
    Route::resource('book', 'BookController');
});

You don't need to give local path. just give cdn link of bootstrap datetimepicker. and it works.

No. To do it just once you would simply write the delete statement for the table you want to cascade.

DELETE FROM some_child_table WHERE some_fk_field IN (SELECT some_id FROM some_Table);
DELETE FROM some_table;

The way of dknaack does not work for me, I found this solution as well:

@Html.DropDownList("Chapters", ViewBag.Chapters as SelectList, 
                    "Select chapter", new { @onchange = "location = this.value;" })

where

@Html.DropDownList(controlName, ViewBag.property + cast, "Default value", @onchange event)

In the controller you can add:

DbModel db = new DbModel();    //entity model of Entity Framework

ViewBag.Chapters = new SelectList(db.T_Chapter, "Id", "Name");

  <label for="profileImage"> 
  <a style="cursor: pointer;"><em class="fa fa-upload"></em> Change Profile 
  Image</a></label> 
  <input type="file" name="profileImage" id="profileImage" style="display: none;">

This method is only for those who know that Mysql is installed but still mysql_config can't be find. This happens if python install can't find mysql_config in your system path, which mostly happens if you have done the installation via .dmg Mac Package or installed at some custom path. The easiest and documented way by MySqlDB is to change the site.cfg. Find the mysql_config which is probably in /usr/local/mysql/bin/ and change the variable namely mysql_config just like below and run the installation again. Don't forget to un-comment it by removing "#"

Change below line

"#mysql_config = /usr/local/bin/mysql_config"

to

"mysql_config = /usr/local/mysql/bin/mysql_config"

depending upon the path in your system.

By the way I used python install after changing the site.cfg

sudo /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python setup.py install

The Git Parable explains how a typical DVCS gets created and why their creators did what they did. Also, you might want to take a look at Git for Computer Scientist; it explains what each type of object in Git does, including branches and tags.

^{Assuming you actually mean timestamp because there is no datetime in Postgres}

Cast the timestamp column to a date, that will remove the time part:

select *
from the_table
where the_timestamp_column::date = date '2015-07-15';

This will return all rows from July, 15th.

Note that the above will not use an index on the_timestamp_column. If performance is critical, you need to either create an index on that expression or use a range condition:

select *
from the_table
where the_timestamp_column >= timestamp '2015-07-15 00:00:00'
  and the_timestamp_column < timestamp '2015-07-16 00:00:00';

I am also a Windows user. And I have installed Python 3.7 and when I try to install any package it throws the same error that you are getting.

Try this out. This worked for me.

python -m pip install numpy

And whenever you install new package just write python -m pip install <package_name>

Hope this is helpful.

You can turn the axes off by following the advice in Veedrac's comment (linking to here) with one small modification.

Rather than using plt.axis('off') you should use ax.axis('off') where ax is a matplotlib.axes object. To do this for your code you simple need to add axarr[0,0].axis('off') and so on for each of your subplots.

The code below shows the result (I've removed the prune_matrix part because I don't have access to that function, in the future please submit fully working code.)

import matplotlib.pyplot as plt
import matplotlib.image as mpimg
import matplotlib.cm as cm

img = mpimg.imread("stewie.jpg")

f, axarr = plt.subplots(2, 2)
axarr[0,0].imshow(img, cmap = cm.Greys_r)
axarr[0,0].set_title("Rank = 512")
axarr[0,0].axis('off')

axarr[0,1].imshow(img, cmap = cm.Greys_r)
axarr[0,1].set_title("Rank = %s" % 128)
axarr[0,1].axis('off')

axarr[1,0].imshow(img, cmap = cm.Greys_r)
axarr[1,0].set_title("Rank = %s" % 32)
axarr[1,0].axis('off')

axarr[1,1].imshow(img, cmap = cm.Greys_r)
axarr[1,1].set_title("Rank = %s" % 16)
axarr[1,1].axis('off')

plt.show()

Note: To turn off only the x or y axis you can use set_visible() e.g.:

axarr[0,0].xaxis.set_visible(False) # Hide only x axis

box-shadow: -15px 0px 17px -7px rgba(0,0,0,0.75);

The first px value is the "Horizontal Length" set to -15px to position the shadow towards the left, the next px value is set to 0 so the shadow top and bottom is centred to minimise the top and bottom shadow.

The third value(17px) is known as the blur radius. The higher the number, the more blurred the shadow will be. And then last px value -7px is The spread radius, a positive value increases the size of the shadow, a negative value decreases the size of the shadow, at -7px it keeps the shadow from appearing above and below the item.

You can write different sheets as follows

     if($work_sheet==0){
         $objWorkSheet->setTitle("Worksheet$work_sheet");
         $objPHPExcel->setActiveSheetIndex($work_sheet)->setCellValue('A1', 'SR No. In sheet 1')->getStyle('A1')->getFont()->setBold(true);
         $objPHPExcel->setActiveSheetIndex($work_sheet)->setCellValueByColumnAndRow($col++, $row++, $i++);//setting value by column and row indexes if needed
     }
     if($work_sheet==1){
         $objWorkSheet->setTitle("Worksheet$work_sheet");
         $objPHPExcel->setActiveSheetIndex($work_sheet)->setCellValue('A1', 'SR No. In sheet 2')->getStyle('A1')->getFont()->setBold(true);
         $objPHPExcel->setActiveSheetIndex($work_sheet)->setCellValueByColumnAndRow($col++, $row++, $i++);//setting value by column and row indexes if needed

         $objPHPExcel->setActiveSheetIndex($work_sheet)->setCellValue('A1', 'SR No. In sheet 3')->getStyle('A1')->getFont()->setBold(true);
         $objPHPExcel->setActiveSheetIndex($work_sheet)->setCellValueByColumnAndRow($col++, $row++, $i++);//setting value by column and row indexes if needed
     }
     $work_sheet++;

You can just say

callback();

Alternately you can use the call method if you want to adjust the value of this within the callback.

callback.call( newValueForThis);

Inside the function this would be whatever newValueForThis is.

Did you enable the profile for SQL Server Agent? This a common step that is missed when creating Email profiles in DatabaseMail.

Steps:

• Right-click on SQL Server Agent in Object Explorer (SSMS)
• Click on Properties
• Click on the Alert System tab in the left-hand navigation
• Enable the mail profile
• Set Mail System and Mail Profile
• Click OK
• Restart SQL Server Agent

Encountered a similar problem after upgrading to Catalina OS. After running mysqld command, I found that there was some issue with the logs file. It could be different for others.

Sometimes it is effectively impossible (with some exceptions of where you might be lucky to have additional data) and the solutions here wont work.

Git doesn't preserve ref history (which includes branches). It only stores the current position for each branch (the head). This means you can lose some branch history in git over time. Whenever you branch for example, it's immediately lost which branch was the original one. All a branch does is:

git checkout branch1    # refs/branch1 -> commit1
git checkout -b branch2 # branch2 -> commit1

You might assume that the first commited to is the branch. This tends to be the case but it's not always so. There's nothing stopping you from commiting to either branch first after the above operation. Additionally, git timestamps aren't guaranteed to be reliable. It's not until you commit to both that they truly become branches structurally.

While in diagrams we tend to number commits conceptually, git has no real stable concept of sequence when the commit tree branches. In this case you can assume the numbers (indicating order) are determined by timestamp (it might be fun to see how a git UI handles things when you set all the timestamps to the same).

This is what a human expect conceptually:

After branch:
       C1 (B1)
      /
    -
      \
       C1 (B2)
After first commit:
       C1 (B1)
      /
    - 
      \
       C1 - C2 (B2)

This is what you actually get:

After branch:
    - C1 (B1) (B2)
After first commit (human):
    - C1 (B1)
        \
         C2 (B2)
After first commit (real):
    - C1 (B1) - C2 (B2)

You would assume B1 to be the original branch but it could infact simply be a dead branch (someone did checkout -b but never committed to it). It's not until you commit to both that you get a legitimate branch structure within git:

Either:
      / - C2 (B1)
    -- C1
      \ - C3 (B2)
Or:
      / - C3 (B1)
    -- C1
      \ - C2 (B2)

You always know that C1 came before C2 and C3 but you never reliably know if C2 came before C3 or C3 came before C2 (because you can set the time on your workstation to anything for example). B1 and B2 is also misleading as you can't know which branch came first. You can make a very good and usually accurate guess at it in many cases. It is a bit like a race track. All things generally being equal with the cars then you can assume that a car that comes in a lap behind started a lap behind. We also have conventions that are very reliable, for example master will nearly always represent the longest lived branches although sadly I have seen cases where even this is not the case.

The example given here is a history preserving example:

Human:
    - X - A - B - C - D - F (B1)
           \     / \     /
            G - H ----- I - J (B2)
Real:
            B ----- C - D - F (B1)
           /       / \     /
    - X - A       /   \   /
           \     /     \ /
            G - H ----- I - J (B2)

Real here is also misleading because we as humans read it left to right, root to leaf (ref). Git does not do that. Where we do (A->B) in our heads git does (A<-B or B->A). It reads it from ref to root. Refs can be anywhere but tend to be leafs, at least for active branches. A ref points to a commit and commits only contain a like to their parent/s, not to their children. When a commit is a merge commit it will have more than one parent. The first parent is always the original commit that was merged into. The other parents are always commits that were merged into the original commit.

Paths:
    F->(D->(C->(B->(A->X)),(H->(G->(A->X))))),(I->(H->(G->(A->X))),(C->(B->(A->X)),(H->(G->(A->X)))))
    J->(I->(H->(G->(A->X))),(C->(B->(A->X)),(H->(G->(A->X)))))

This is not a very efficient representation, rather an expression of all the paths git can take from each ref (B1 and B2).

Git's internal storage looks more like this (not that A as a parent appears twice):

    F->D,I | D->C | C->B,H | B->A | A->X | J->I | I->H,C | H->G | G->A

If you dump a raw git commit you'll see zero or more parent fields. If there are zero, it means no parent and the commit is a root (you can actually have multiple roots). If there's one, it means there was no merge and it's not a root commit. If there is more than one it means that the commit is the result of a merge and all of the parents after the first are merge commits.

Paths simplified:
    F->(D->C),I | J->I | I->H,C | C->(B->A),H | H->(G->A) | A->X
Paths first parents only:
    F->(D->(C->(B->(A->X)))) | F->D->C->B->A->X
    J->(I->(H->(G->(A->X))) | J->I->H->G->A->X
Or:
    F->D->C | J->I | I->H | C->B->A | H->G->A | A->X
Paths first parents only simplified:
    F->D->C->B->A | J->I->->G->A | A->X
Topological:
    - X - A - B - C - D - F (B1)
           \
            G - H - I - J (B2)

When both hit A their chain will be the same, before that their chain will be entirely different. The first commit another two commits have in common is the common ancestor and from whence they diverged. there might be some confusion here between the terms commit, branch and ref. You can in fact merge a commit. This is what merge really does. A ref simply points to a commit and a branch is nothing more than a ref in the folder .git/refs/heads, the folder location is what determines that a ref is a branch rather than something else such as a tag.

Where you lose history is that merge will do one of two things depending on circumstances.

Consider:

      / - B (B1)
    - A
      \ - C (B2)

In this case a merge in either direction will create a new commit with the first parent as the commit pointed to by the current checked out branch and the second parent as the commit at the tip of the branch you merged into your current branch. It has to create a new commit as both branches have changes since their common ancestor that must be combined.

      / - B - D (B1)
    - A      /
      \ --- C (B2)

At this point D (B1) now has both sets of changes from both branches (itself and B2). However the second branch doesn't have the changes from B1. If you merge the changes from B1 into B2 so that they are syncronised then you might expect something that looks like this (you can force git merge to do it like this however with --no-ff):

Expected:
      / - B - D (B1)
    - A      / \
      \ --- C - E (B2)
Reality:
      / - B - D (B1) (B2)
    - A      /
      \ --- C

You will get that even if B1 has additional commits. As long as there aren't changes in B2 that B1 doesn't have, the two branches will be merged. It does a fast forward which is like a rebase (rebases also eat or linearise history), except unlike a rebase as only one branch has a change set it doesn't have to apply a changeset from one branch on top of that from another.

From:
      / - B - D - E (B1)
    - A      /
      \ --- C (B2)
To:
      / - B - D - E (B1) (B2)
    - A      /
      \ --- C

If you cease work on B1 then things are largely fine for preserving history in the long run. Only B1 (which might be master) will advance typically so the location of B2 in B2's history successfully represents the point that it was merged into B1. This is what git expects you to do, to branch B from A, then you can merge A into B as much as you like as changes accumulate, however when merging B back into A, it's not expected that you will work on B and further. If you carry on working on your branch after fast forward merging it back into the branch you were working on then your erasing B's previous history each time. You're really creating a new branch each time after fast forward commit to source then commit to branch. You end up with when you fast forward commit is lots of branches/merges that you can see in the history and structure but without the ability to determine what the name of that branch was or if what looks like two separate branches is really the same branch.

         0   1   2   3   4 (B1)
        /-\ /-\ /-\ /-\ /
    ----   -   -   -   -
        \-/ \-/ \-/ \-/ \
         5   6   7   8   9 (B2)

1 to 3 and 5 to 8 are structural branches that show up if you follow the history for either 4 or 9. There's no way in git to know which of this unnamed and unreferenced structural branches belong to with of the named and references branches as the end of the structure. You might assume from this drawing that 0 to 4 belongs to B1 and 4 to 9 belongs to B2 but apart from 4 and 9 was can't know which branch belongs to which branch, I've simply drawn it in a way that gives the illusion of that. 0 might belong to B2 and 5 might belong to B1. There are 16 different possibilies in this case of which named branch each of the structural branches could belong to. This is assuming that none of these structural branches came from a deleted branch or as a result of merging a branch into itself when pulling from master (the same branch name on two repos is infact two branches, a separate repository is like branching all branches).

There are a number of git strategies that work around this. You can force git merge to never fast forward and always create a merge branch. A horrible way to preserve branch history is with tags and/or branches (tags are really recommended) according to some convention of your choosing. I realy wouldn't recommend a dummy empty commit in the branch you're merging into. A very common convention is to not merge into an integration branch until you want to genuinely close your branch. This is a practice that people should attempt to adhere to as otherwise you're working around the point of having branches. However in the real world the ideal is not always practical meaning doing the right thing is not viable for every situation. If what you're doing on a branch is isolated that can work but otherwise you might be in a situation where when multiple developers are working one something they need to share their changes quickly (ideally you might really want to be working on one branch but not all situations suit that either and generally two people working on a branch is something you want to avoid).

Another way of configuring nvcc to use a specific version of gcc (gcc-4.4, for instance), is to edit nvcc.profile and alter PATH to include the path to the gcc you want to use first.

For example (gcc-4.4.6 installed in /opt):

PATH += /opt/gcc-4.4.6/lib/gcc/x86_64-unknown-linux-gnu/4.4.6:/opt/gcc-4.4.6/bin:$(TOP)/open64/bin:$(TOP)/share/cuda/nvvm:$(_HERE_):

The location of nvcc.profile varies, but it should be in the same directory as the nvcc executable itself.

This is a bit of a hack, as nvcc.profile is not intended for user configuration as per the nvcc manual, but it was the solution which worked best for me.

Give the form an id, and then:

document.getElementById("yourFormId").submit();

Best practice would probably be to give your link an id too, and get rid of the event handler:

document.getElementById("yourLinkId").onclick = function() {
    document.getElementById("yourFormId").submit();
}

The best and easy solution for solving this issue is pass your data from this function in controller.

$scope.trustSrcurl = function(data) 
{
    return $sce.trustAsResourceUrl(data);
}

In html page

<iframe class="youtube-player" type="text/html" width="640" height="385" ng-src="{{trustSrcurl(video.src)}}" allowfullscreen frameborder="0"></iframe>

<html lang="en">
<head>
    <title>Jquery - get ip address</title>
    <script type="text/javascript" src="//cdn.jsdelivr.net/jquery/1/jquery.min.js"></script>
</head>
<body>


<h1>Your Ip Address : <span class="ip"></span></h1>


<script type="text/javascript">

        $(".ip").text(data.ip);
    });

The ggrepel package works great for repelling overlapping text labels away from each other. You can use either geom_label_repel() (draws rectangles around the text) or geom_text_repel() functions.

library(ggplot2)
library(ggrepel)

nba <- read.csv("http://datasets.flowingdata.com/ppg2008.csv", sep = ",")

nbaplot <- ggplot(nba, aes(x= MIN, y = PTS)) + 
  geom_point(color = "blue", size = 3)

### geom_label_repel
nbaplot + 
  geom_label_repel(aes(label = Name),
                  box.padding   = 0.35, 
                  point.padding = 0.5,
                  segment.color = 'grey50') +
  theme_classic()

### geom_text_repel
# only label players with PTS > 25 or < 18
# align text vertically with nudge_y and allow the labels to 
# move horizontally with direction = "x"
ggplot(nba, aes(x= MIN, y = PTS, label = Name)) + 
  geom_point(color = dplyr::case_when(nba$PTS > 25 ~ "#1b9e77", 
                                      nba$PTS < 18 ~ "#d95f02",
                                      TRUE ~ "#7570b3"), 
             size = 3, alpha = 0.8) +
  geom_text_repel(data          = subset(nba, PTS > 25),
                  nudge_y       = 32 - subset(nba, PTS > 25)$PTS,
                  size          = 4,
                  box.padding   = 1.5,
                  point.padding = 0.5,
                  force         = 100,
                  segment.size  = 0.2,
                  segment.color = "grey50",
                  direction     = "x") +
  geom_label_repel(data         = subset(nba, PTS < 18),
                  nudge_y       = 16 - subset(nba, PTS < 18)$PTS,
                  size          = 4,
                  box.padding   = 0.5,
                  point.padding = 0.5,
                  force         = 100,
                  segment.size  = 0.2,
                  segment.color = "grey50",
                  direction     = "x") +

  scale_y_continuous(expand = expand_scale(mult = c(0.1, .1))) +
  theme_classic(base_size = 16)

Edit: To use ggrepel with lines, see this and this.

Use parseJSON. Look at the doc

var obj = $.parseJSON(data);

Something like this:

$.ajax({     
    type: "POST",
    url: '/admin/systemgoalssystemgoalupdate?format=html',
    data: formdata,
    success: function (data) {

        console.log($.parseJSON(data)); //will log Object

    }
});

To "remove" the 1st character point to the second character:

char mystr[] = "Nmy stringP";
char *p = mystr;
p++; /* 'N' is not in `p` */

To remove the last character replace it with a '\0'.

p[strlen(p)-1] = 0; /* 'P' is not in `p` (and it isn't in `mystr` either) */

you should use a /d before path as below :

cd /d e:\

document.getElementsByClassName('btn-pageMenu') delivers a nodeList. You should use: document.getElementsByClassName('btn-pageMenu')[0].style.display (if it's the first element from that list you want to change.

If you want to change style.display for all nodes loop through the list:

var elems = document.getElementsByClassName('btn-pageMenu');
for (var i=0;i<elems.length;i+=1){
  elems[i].style.display = 'block';
}

to be complete: if you use jquery it is as simple as:

?$('.btn-pageMenu').css('display'???????????????????????????,'block');??????

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

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

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

I use SingleOrDefault in situations where my logic dictates that the will be either zero or one results. If there are more, it's an error situation, which is helpful.

The alternative way to check if an array is empty could be:

count($array)>0

It works for me without that error

using command

npm install bootstrap --save

open .angular.json old (.angular-cli.json ) file find the "styles" add the bootstrap css file

"styles": [
       "src/styles.scss",
       "node_modules/bootstrap/dist/css/bootstrap.min.css"
],

If it's conciseness you're after, you might like:

prop.table(table(tips$smoker))

and then scale by 100 and round if you like. Or more like your exact output:

tbl <- table(tips$smoker)
cbind(tbl,prop.table(tbl))

If you wanted to do this for multiple columns, there are lots of different directions you could go depending on what your tastes tell you is clean looking output, but here's one option:

tblFun <- function(x){
    tbl <- table(x)
    res <- cbind(tbl,round(prop.table(tbl)*100,2))
    colnames(res) <- c('Count','Percentage')
    res
}

do.call(rbind,lapply(tips[3:6],tblFun))
       Count Percentage
Female    87      35.66
Male     157      64.34
No       151      61.89
Yes       93      38.11
Fri       19       7.79
Sat       87      35.66
Sun       76      31.15
Thur      62      25.41
Dinner   176      72.13
Lunch     68      27.87

If you don't like stack the different tables on top of each other, you can ditch the do.call and leave them in a list.

You realise that you may be making a rod for your own back for the future. The pwdencrypt() and pwdcompare() are undocumented functions and may not behave the same in future versions of SQL Server.

Why not hash the password using a predictable algorithm such as SHA-2 or better before hitting the DB?

toast is a bad idea, it's far too "complex" to print the value of a variable. use log or s.o.p, and as drawnonward already said, their output goes to logcat. it only makes sense if you want to expose this information to the end-user...

string founded = FindStringTakeX("UID:   994zxfa6q", "UID:", 9);


string FindStringTakeX(string strValue,string findKey,int take,bool ignoreWhiteSpace = true)
    {
        int index = strValue.IndexOf(findKey) + findKey.Length;

        if (index >= 0)
        {
            if (ignoreWhiteSpace)
            {
                while (strValue[index].ToString() == " ")
                {
                    index++;
                }
            }

            if(strValue.Length >= index + take)
            {
                string result = strValue.Substring(index, take);

                return result;
            }


        }

        return string.Empty;
    }

Simple:

delete myObj.test.key1;

Fredrik has provided the fix, but it may be worth considering why this isn't in the framework to start with. I believe the idea is that the LINQ query operators should be side-effect-free, fitting in with a reasonably functional way of looking at the world. Clearly ForEach is exactly the opposite - a purely side-effect-based construct.

That's not to say this is a bad thing to do - just thinking about the philosophical reasons behind the decision.

If like me you recently moved certain classes to different packages ect. and you use android navigation. Make sure to change the argType to you match you new package address. from:

app:argType="com.example.app.old.Item" 

to:

app:argType="com.example.app.new.Item" 

I don't think you need a case statement. You just need to update your where clause and make sure you have correct parentheses to group the clauses.

SELECT Sum(CAMount) as PaymentAmount 
from TableOrderPayment 
where (CStatus = 'Active' AND CPaymentType = 'Cash') 
OR (CStatus = 'Active' and CPaymentType = 'Check' and CDate<=SYSDATETIME())

The answers posted before mine assume that CDate<=SYSDATETIME() is also appropriate for Cash payment type as well. I think I split mine out so it only looks for that clause for check payments.

If you are in Chrome you can check the Post Data

Here is How to check the Post data

1. Go to Network Tab
2. Look for the Link to which you are sending Post Data
3. Click on it
4. In the Headers, you can check Request Payload to check the post data

Or to build upon what Jar Jar suggested, this is what I used on a recent project (to overcome length restrictions):

var randomString = function (len, bits)
{
    bits = bits || 36;
    var outStr = "", newStr;
    while (outStr.length < len)
    {
        newStr = Math.random().toString(bits).slice(2);
        outStr += newStr.slice(0, Math.min(newStr.length, (len - outStr.length)));
    }
    return outStr.toUpperCase();
};

Use:

randomString(12, 16); // 12 hexadecimal characters
randomString(200); // 200 alphanumeric characters

For environment variable in Maven, you can set below.

you could combine AllisonC's idea with window.open function: http://www.w3schools.com/jsref/met_win_open.asp

function openWin(url) {
    myWindow = window.open(url, '', 'width=800,height=400');
    myWindow.focus();
}

And then on each link you call the openWin function with the right social net url.

I feel the simplest way would be

 from matplotlib import pyplot;
 from pylab import genfromtxt;  
 mat0 = genfromtxt("data0.txt");
 mat1 = genfromtxt("data1.txt");
 pyplot.plot(mat0[:,0], mat0[:,1], label = "data0");
 pyplot.plot(mat1[:,0], mat1[:,1], label = "data1");
 pyplot.legend();
 pyplot.show();

1. label is the string that is displayed on the legend
2. you can plot as many series of data points as possible before show() to plot all of them on the same graph This is the simple way to plot simple graphs. For other options in genfromtxt go to this url.

Write the column name in between DOUBLE quote as in "columnName".

If the error message shows a different character case than what you wrote, it is very likely that your sql client performed an automatic case conversion for you. Use double quote to bypass that. (This works on Squirrell Client 3.0).

my friend and I are currently developing a java library implementing the AODV protocol (multihop routing suitable for mobile networks), in our bachelor thesis. The final 'product' includes a easy way to create/join an adhoc network on several android devices and an interface through the library, to send and receive messages. Unfortunately each type of phone such as hero, nexsus one... have a phonedepended way for createing a adhoc network so currently we are only supporting a few phones).

this means that once this project is finished, people with rooted phones can implement their distributed applications (file sharing, games, ...) by simply including the library .jar file in their android projects.

it's all open source by the way

If you are using Angular and Firebase, you can also use the DTOptionsBuilder :

angular.module('your_module', [
'ui.router',
'oc.lazyLoad',
'ui.bootstrap',
'ngSanitize',
'firebase']).controller("your_controller", function ($scope, $firebaseArray, DTOptionsBuilder) {

var ref = firebase.database().ref().child("your_database_table");

// create a synchronized array
$scope.your_database_table = $firebaseArray(ref);

ref.on('value', snap => {

    $scope.dtOptions = DTOptionsBuilder.newOptions()
        .withOption('language',
        {
            "sProcessing": "Traitement en cours...",
            "sSearch": "Rechercher :",
            "sLengthMenu": "Afficher _MENU_ éléments",
            "sInfo": "Affichage de l'élément _START_ à _END_ sur _TOTAL_ éléments",
            "sInfoEmpty": "Affichage de l'élément 0 à 0 sur 0 élément",
            "sInfoFiltered": "(filtré de _MAX_ éléments au total)",
            "sInfoPostFix": "",

            }
        }
        )

});})

I hope this will help.

I've been using Nuitka and PyInstaller with my package, PySimpleGUI.

Nuitka There were issues getting tkinter to compile with Nuikta. One of the project contributors developed a script that fixed the problem.

If you're not using tkinter it may "just work" for you. If you are using tkinter say so and I'll try to get the script and instructions published.

PyInstaller I'm running 3.6 and PyInstaller is working great! The command I use to create my exe file is:

pyinstaller -wF myfile.py

The -wF will create a single EXE file. Because all of my programs have a GUI and I do not want to command window to show, the -w option will hide the command window.

This is as close to getting what looks like a Winforms program to run that was written in Python.

[Update 20-Jul-2019]

There is PySimpleGUI GUI based solution that uses PyInstaller. It uses PySimpleGUI. It's called pysimplegui-exemaker and can be pip installed.

pip install PySimpleGUI-exemaker

To run it after installing:

python -m pysimplegui-exemaker.pysimplegui-exemaker

I think when we use onClick we want to do something different than default. So, for all your links with onClick:

$("a[onClick]").on("click", function(e) {
  return e.preventDefault();
});

First of all I'd like to say that I 100% agree with John Saunders that you must avoid loops in SQL in most cases especially in production.

But occasionally as a one time thing to populate a table with a hundred records for testing purposes IMHO it's just OK to indulge yourself to use a loop.

For example in your case to populate your table with records with hospital ids between 16 and 100 and make emails and descriptions distinct you could've used

CREATE PROCEDURE populateHospitals
AS
DECLARE @hid INT;
SET @hid=16;
WHILE @hid < 100
BEGIN 
    INSERT hospitals ([Hospital ID], Email, Description) 
    VALUES(@hid, 'user' + LTRIM(STR(@hid)) + '@mail.com', 'Sample Description' + LTRIM(STR(@hid))); 
    SET @hid = @hid + 1;
END

And result would be

ID   Hospital ID Email            Description          
---- ----------- ---------------- ---------------------
1    16          [email protected]  Sample Description16 
2    17          [email protected]  Sample Description17 
...                                                    
84   99          [email protected]  Sample Description99 

Mine was not having @Entity on the many side entity

@Entity // this was commented
@Table(name = "some_table")
public class ChildEntity {
    @JoinColumn(name = "parent", referencedColumnName = "id")
    @ManyToOne
    private ParentEntity parentEntity;
}

toString() only returns the exception name and the optional message. I would suggest calling

exception.printStackTrace()

to dump the message, or if you need the gory details:

 StackTraceElement[] trace = exception.getStackTrace()

Make sure return type of you method is same what you want to return. Eg: `

  public int get(int[] r)
  {
     return r[0];
  }

`

Note : return type is int, not int[], so it is able to return int.

In general, prototype can be

public Type get(Type[] array, int index)
{
    return array[index];
}

try using for example

N=2
rep(1:4, each = N) 

as an index

The InstallUtil.exe tool is simply a wrapper around some reflection calls against the installer component(s) in your service. As such, it really doesn't do much but exercise the functionality these installer components provide. Marc Gravell's solution simply provides a means to do this from the command line so that you no longer have to rely on having InstallUtil.exe on the target machine.

Here's my step-by-step that based on Marc Gravell's solution.

How to make a .NET Windows Service start right after the installation?

You can also watch the output like this:

final Process p = Runtime.getRuntime().exec("java -jar map.jar time.rel test.txt debug");

new Thread(new Runnable() {
    public void run() {
        BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
        String line = null;

        try {
            while ((line = input.readLine()) != null)
                System.out.println(line);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}).start();

p.waitFor();

And don't forget, if you are running a windows command, you need to put cmd /c in front of your command.

EDIT: And for bonus points, you can also use ProcessBuilder to pass input to a program:

String[] command = new String[] {
        "choice",
        "/C",
        "YN",
        "/M",
        "\"Press Y if you're cool\""
};
String inputLine = "Y";

ProcessBuilder pb = new ProcessBuilder(command);
pb.redirectErrorStream(true);
Process p = pb.start();
BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(p.getOutputStream()));

writer.write(inputLine);
writer.newLine();
writer.close();

String line;

while ((line = reader.readLine()) != null) {
    System.out.println(line);
}

This will run the windows command choice /C YN /M "Press Y if you're cool" and respond with a Y. So, the output will be:

Press Y if you're cool [Y,N]?Y

For fixing such an issue I have used below code

a.divide(b, 2, RoundingMode.HALF_EVEN)

2 is precision. Now problem was resolved.

To search for multiple matches in each file, we can sequence several Select-String calls:

Get-ChildItem C:\Logs |
  where { $_ | Select-String -Pattern 'VendorEnquiry' } |
  where { $_ | Select-String -Pattern 'Failed' } |
  ...

At each step, files that do not contain the current pattern will be filtered out, ensuring that the final list of files contains all of the search terms.

Rather than writing out each Select-String call manually, we can simplify this with a filter to match multiple patterns:

filter MultiSelect-String( [string[]]$Patterns ) {
  # Check the current item against all patterns.
  foreach( $Pattern in $Patterns ) {
    # If one of the patterns does not match, skip the item.
    $matched = @($_ | Select-String -Pattern $Pattern)
    if( -not $matched ) {
      return
    }
  }

  # If all patterns matched, pass the item through.
  $_
}

Get-ChildItem C:\Logs | MultiSelect-String 'VendorEnquiry','Failed',...

Now, to satisfy the "Logtime about 11:30 am" part of the example would require finding the log time corresponding to each failure entry. How to do this is highly dependent on the actual structure of the files, but testing for "about" is relatively simple:

function AboutTime( [DateTime]$time, [DateTime]$target, [TimeSpan]$epsilon ) {
  $time -le ($target + $epsilon) -and $time -ge ($target - $epsilon)
}

PS> $epsilon = [TimeSpan]::FromMinutes(5)
PS> $target = [DateTime]'11:30am'
PS> AboutTime '11:00am' $target $epsilon
False
PS> AboutTime '11:28am' $target $epsilon
True
PS> AboutTime '11:35am' $target $epsilon
True

Based from this thread, you need to bookmark chrome://settings/languages and then Drag and Drop the language to make it default. You have to click on the Display Google Chrome in this Language button and completely restart Chrome.

It can be installed with below simple command:

pip3 install pyqt5

If you want to revert the file to its state in master:

git checkout origin/master [filename]

grep ‘string1\|string2’ FILENAME 

GNU grep version 3.1

I had similar issue and tried all possible combinations as well as accepted answer without any luck. Finally I found DigiCert SSL Utility which helped me to install certificate in couple clicks. You can download it here. Hope this answer will save some time for others.

You may create a new list with an input of a previous list like so:

List one = new ArrayList()
//... add data, sort, etc
List two = new ArrayList(one);

This will allow you to modify the order or what elemtents are contained independent of the first list.

Keep in mind that the two lists will contain the same objects though, so if you modify an object in List two, the same object will be modified in list one.

example:

MyObject value1 = one.get(0);
MyObject value2 = two.get(0);
value1 == value2 //true
value1.setName("hello");
value2.getName(); //returns "hello"

Edit

To avoid this you need a deep copy of each element in the list like so:

List<Torero> one = new ArrayList<Torero>();
//add elements

List<Torero> two = new Arraylist<Torero>();
for(Torero t : one){
    Torero copy = deepCopy(t);
    two.add(copy);
}

with copy like the following:

public Torero deepCopy(Torero input){
    Torero copy = new Torero();
    copy.setValue(input.getValue());//.. copy primitives, deep copy objects again

    return copy;
}

It's all about performance and development speed. Of course, if you are a good programmer and design something that is really tailored to your needs, you might achieve better performance than if you had used a Javascript framework. But do you have the time to do it all by yourself?

My personal opinion is that Javascript is incredibly useful and overused, but that if you really need it, a framework is the way to go.

Now comes the choice of the framework. For what benchmarks are worth, you can find one at http://ejohn.org/files/142/ . It also depends on which plugins are available and what you intend to do with them. I started using jQuery because it seemed to be maintained and well featured, even though it wasn't the fastest at that moment. I do not regret it but I didn't test anything else since then.

Here is the good function for pre PHP 5: I added GMT difference at the end, it's not hardcoded.

function iso8601($time=false) {
    if ($time === false) $time = time();
    $date = date('Y-m-d\TH:i:sO', $time);
    return (substr($date, 0, strlen($date)-2).':'.substr($date, -2));
}

The error pretty much explains what the problem is: you are trying to include a file that is not there.

Try to use the full path to the file, using realpath(), and use dirname(__FILE__) to get your current directory:

require_once(realpath(dirname(__FILE__) . '/../includes/dbconn.inc'));

connectionString="Server=dbsrv;User ID=myDbUser;Password=somepass"word"

Since the web.config is XML, you need to escape the five special characters:

& -> & ampersand, U+0026
< -> < left angle bracket, less-than sign, U+003C
> -> > right angle bracket, greater-than sign, U+003E
" -> " quotation mark, U+0022
' -> ' apostrophe, U+0027

+ is not a problem, I suppose.

Duc Filan adds: You should also wrap your password with single quote ':

connectionString="Server=dbsrv;User ID=myDbUser;Password='somepass"word'"

FPM is a process manager to manage the FastCGI SAPI (Server API) in PHP.

Basically, it replaces the need for something like SpawnFCGI. It spawns the FastCGI children adaptively (meaning launching more if the current load requires it).

Otherwise, there's not much operating difference between it and FastCGI (The request pipeline from start of request to end is the same). It's just there to make implementing it easier.

You can use the onchange event:

<form name="myform" id="myform" action="action.php">
    <input type="hidden" name="myinput" value="0" onchange="this.form.submit()"/>
    <input type="text" name="message" value="" />
    <input type="submit" name="submit" onclick="DoSubmit()" />
</form>

As the previous answers exhaustively covered the theory behind the value categories, there is just another thing I'd like to add: you can actually play with it and test it.

For some hands-on experimentation with the value categories, you can make use of the decltype specifier. Its behavior explicitly distinguishes between the three primary value categories (xvalue, lvalue, and prvalue).

Using the preprocessor saves us some typing ...

Primary categories:

#define IS_XVALUE(X) std::is_rvalue_reference<decltype((X))>::value
#define IS_LVALUE(X) std::is_lvalue_reference<decltype((X))>::value
#define IS_PRVALUE(X) !std::is_reference<decltype((X))>::value

Mixed categories:

#define IS_GLVALUE(X) (IS_LVALUE(X) || IS_XVALUE(X))
#define IS_RVALUE(X) (IS_PRVALUE(X) || IS_XVALUE(X))

Now we can reproduce (almost) all the examples from cppreference on value category.

Here are some examples with C++17 (for terse static_assert):

void doesNothing(){}
struct S
{
    int x{0};
};
int x = 1;
int y = 2;
S s;

static_assert(IS_LVALUE(x));
static_assert(IS_LVALUE(x+=y));
static_assert(IS_LVALUE("Hello world!"));
static_assert(IS_LVALUE(++x));

static_assert(IS_PRVALUE(1));
static_assert(IS_PRVALUE(x++));
static_assert(IS_PRVALUE(static_cast<double>(x)));
static_assert(IS_PRVALUE(std::string{}));
static_assert(IS_PRVALUE(throw std::exception()));
static_assert(IS_PRVALUE(doesNothing()));

static_assert(IS_XVALUE(std::move(s)));
// The next one doesn't work in gcc 8.2 but in gcc 9.1. Clang 7.0.0 and msvc 19.16 are doing fine.
static_assert(IS_XVALUE(S().x)); 

The mixed categories are kind of boring once you figured out the primary category.

For some more examples (and experimentation), check out the following link on compiler explorer. Don't bother reading the assembly, though. I added a lot of compilers just to make sure it works across all the common compilers.

I'm would recommend it:

<style>
    .clearfix {
       *zoom: 1;
    }
    .clearfix:before,
    .clearfix:after {
        content: " ";
        display: table;
    }
    .clearfix:after {
        clear: both;
    }
    ul.list {
       list-style: none;
    }
    ul.list li {
       display: inline-block;
    }
</style>

<ul class="list clearfix">
    <li>li-one</li>
    <li>li-two</li>
    <li>li-three</li>
    <li>li-four</li>
</ul>

Of course, this is not generic answer

Windows7 FireFox/Chrome:

    {
       "cmd":["F:\\Program Files\\Mozilla Firefox\\firefox.exe","$file"]
    }

just use your own path of firefox.exe or chrome.exe to replace mine.

Replace firefox.exe or chrome.exe with your own path.

If the constructor of a class is private then you cannot create an object for class from outside of it.

class Test{
 int x, y;
 private Test(){
  .......
  .......
  }
}

We cannot create an object for above class from outside of it. So you cannot access x, y from outside of the class. Then what is the use of this class?
Here is the Answer : FACTORY method.
Add the below method in above class

public static Test getObject(){
  return new Test();
}

So now you can create an object for this class from outside of it. Like the way...

Test t = Test.getObject();

Hence, a static method which returns the object of the class by executing its private constructor is called as FACTORY method
.

IO bound processes: spend more time doing IO than computations, have many short CPU bursts. CPU bound processes: spend more time doing computations, few very long CPU bursts

You can add ng-change directive to input fields. Have a look at the docs example.

I have the log4j.properties configured properly. That's not the problem. After a while I discovered that the problem was in Eclipse IDE which had an old build in "cache" and didn't create a new one (Maven dependecy problem). I had to build the project manually and now it works.

Uninstall the old app from the device/emulator. It worked for me

Iterators make your code more generic.
Every standard library container provides an iterator hence if you change your container class in future the loop wont be affected.

I am using 11.2 and received timeouts.

I resolved by using the version of jsoup below.

    <dependency>
        <groupId>org.jsoup</groupId>
        <artifactId>jsoup</artifactId>
        <version>1.7.2</version>
        <scope>compile</scope>
    </dependency>

Certain MySQL engines support foreign keys. For example, InnoDB can establish constraints based on foreign keys. If you try to delete an entry in one table that has dependents in another, the delete will fail.

If you are using a table type in MySQL, such as MyISAM, that doesn't support foreign keys, you don't link the tables anywhere except your diagrams and queries.

For example, in a query you link two tables in a select statement with a join:

SELECT a, b from table1 LEFT JOIN table2 USING (common_field);

http://jsfiddle.net/ZDgRG/

See above link. I use css to hide the default text and use a label to show what I want:

<div><input type='file' title="Choose a video please" id="aa" onchange="pressed()"><label id="fileLabel">Choose file</label></div>

input[type=file]{
    width:90px;
    color:transparent;
}

window.pressed = function(){
    var a = document.getElementById('aa');
    if(a.value == "")
    {
        fileLabel.innerHTML = "Choose file";
    }
    else
    {
        var theSplit = a.value.split('\\');
        fileLabel.innerHTML = theSplit[theSplit.length-1];
    }
};

Here's a function I wrote another application. Feel free to reuse:

function writeCookie (key, value, days) {
    var date = new Date();

    // Default at 365 days.
    days = days || 365;

    // Get unix milliseconds at current time plus number of days
    date.setTime(+ date + (days * 86400000)); //24 * 60 * 60 * 1000

    window.document.cookie = key + "=" + value + "; expires=" + date.toGMTString() + "; path=/";

    return value;
};

I'm going on a bit of an assumption here, but I'm assuming the logic inside the procedure gets split up via task. And you cant have nullable parameters as @Yuck suggested because of the dynamics of the parameters?

So going by my assumption

If TaskName = "Path1" Then Something

If TaskName = "Path2" Then Something Else

My initial thought is, if you have separate functions with business-logic you need to create, and you can determine that you have say 5-10 different scenarios, rather write individual stored procedures as needed, instead of trying one huge one solution fits all approach. Might get a bit messy to maintain.

But if you must...

Why not try dynamic SQL, as suggested by @E.J Brennan (Forgive me, i haven't touched SQL in a while so my syntax might be rusty) That being said i don't know if its the best approach, but could this could possibly meet your needs?

CREATE PROCEDURE GetTaskEvents
    @TaskName varchar(50)
    @Values varchar(200)
AS
BEGIN
  DECLARE @SQL VARCHAR(MAX)

  IF @TaskName = 'Something'
  BEGIN
    @SQL = 'INSERT INTO.....' + CHAR(13)
    @SQL += @Values + CHAR(13) 
  END

  IF @TaskName = 'Something Else'
  BEGIN
    @SQL = 'DELETE SOMETHING WHERE' + CHAR(13)
    @SQL += @Values + CHAR(13) 
  END

  PRINT(@SQL)
  EXEC(@SQL)    
END

(The CHAR(13) adds a new line.. an old habbit i picked up somewhere, used to help debugging/reading dynamic procedures when running SQL profiler.)

TL;DR: Perform a clean re-install of Visual Studio

After wasting several hours, I still couldn't fix it for Visual Studio 2017. I then installed Visual Studio 2019 PREVIEW and all of a sudden, IntelliSense displays me the members of STL-classes again (which it doesn't with Visual Studio 2017).

So, my guess is that there might be also something wrong with Visual Studio itself (maybe something in the cache directory or in general something on your PC which is not directly related to a specific solution) which can be solved by a clean and complete re-installation of Visual Studio. I know, this is a stupid "solution", but in my case, only a fresh Visual Studio (2019) installation had an effect.

As already mentioned, in my case, only STL classes were affected. IntelliSense wouldn't display their members which is odd. I thought, it could maybe have something to do with precompiled headers. Somewhere I read that the STL and the project should be on the same drive and putting them onto the same should solve the problem. But none of these routes led to success.

Be careful, - has a special meaning with regexp. In a [], you can put it without problem if it is placed at the end. In your case, ,-: is taken as from , to :.

To do this you need a JDBC Connection and/or driver that supports logging the sql at a low level.

Take a look at log4jdbc

int and long were "unified" a few versions back. Before that it was possible to overflow an int through math ops.

3.x has further advanced this by eliminating long altogether and only having int.

• Python 2: sys.maxint contains the maximum value a Python int can hold.
  • On a 64-bit Python 2.7, the size is 24 bytes. Check with sys.getsizeof().
• Python 3: sys.maxsize contains the maximum size in bytes a Python int can be.
  • This will be gigabytes in 32 bits, and exabytes in 64 bits.
  • Such a large int would have a value similar to 8 to the power of sys.maxsize.

You can make this method static.

public static void startChronometer(){
        mChronometer.start();
        showElapsedTime();
    } 

you can call this function in other class as below:

MainActivity.startChronometer();

OR

You can make an object of the main class in second class like,

MainActivity mActivity = new MainActivity();
mActivity.startChronometer();

With Android O the behaviour of the ANDROID_ID will change. The ANDROID_ID will be different per app per user on the phone.

Taken from: https://android-developers.googleblog.com/2017/04/changes-to-device-identifiers-in.html

Android ID

In O, Android ID (Settings.Secure.ANDROID_ID or SSAID) has a different value for each app and each user on the device. Developers requiring a device-scoped identifier, should instead use a resettable identifier, such as Advertising ID, giving users more control. Advertising ID also provides a user-facing setting to limit ad tracking.

Additionally in Android O:

• The ANDROID_ID value won't change on package uninstall/reinstall, as long as the package name and signing key are the same. Apps can rely on this value to maintain state across reinstalls.
• If an app was installed on a device running an earlier version of Android, the Android ID remains the same when the device is updated to Android O, unless the app is uninstalled and reinstalled.
• The Android ID value only changes if the device is factory reset or if the signing key rotates between uninstall and
  reinstall events.
• This change is only required for device manufacturers shipping with Google Play services and Advertising ID. Other device manufacturers may provide an alternative resettable ID or continue to provide ANDROID ID.

Like this:

numrows = len(input)    # 3 rows in your example
numcols = len(input[0]) # 2 columns in your example

Assuming that all the sublists have the same length (that is, it's not a jagged array).

Find parameters

The parameters find function takes are as follows:

1. conditions «Object».
2. [projection] «Object|String» optional fields to return, see Query.prototype.select()
3. [options] «Object» optional see Query.prototype.setOptions()
4. [callback] «Function»

How to limit

const Post = require('./models/Post');

Post.find(
  { published: true }, 
  null, 
  { sort: { 'date': 'asc' }, limit: 20 },
  function(error, posts) {
   if (error) return `${error} while finding from post collection`;

   return posts; // posts with sorted length of 20
  }
);

Extra Info

Mongoose allows you to query your collections in different ways like: Official Documentation

// named john and at least 18
MyModel.find({ name: 'john', age: { $gte: 18 }});

// executes, passing results to callback
MyModel.find({ name: 'john', age: { $gte: 18 }}, function (err, docs) {});

// executes, name LIKE john and only selecting the "name" and "friends" fields
MyModel.find({ name: /john/i }, 'name friends', function (err, docs) { })

// passing options
MyModel.find({ name: /john/i }, null, { skip: 10 })

// passing options and executes
MyModel.find({ name: /john/i }, null, { skip: 10 }, function (err, docs) {});

// executing a query explicitly
var query = MyModel.find({ name: /john/i }, null, { skip: 10 })
query.exec(function (err, docs) {});

// using the promise returned from executing a query
var query = MyModel.find({ name: /john/i }, null, { skip: 10 });
var promise = query.exec();
promise.addBack(function (err, docs) {});

In our code we have a specific validator inherited from the BaseValidator class.

This class does the following:

1. Validates the e-mail address against a regular expression.
2. Does a lookup on the MX record for the domain to make sure there is at least a server to deliver to.

This is the closest you can get to validation without actually sending the person an e-mail confirmation link.

I'm pretty new to iOS and Phonegap as well, but I was able to do this by adding in an eventListener. I did the same thing (using the example you reference), and couldn't get it to work. But this seemed to do the trick:

// Event listener to determine change (horizontal/portrait)
window.addEventListener("orientationchange", updateOrientation); 

function updateOrientation(e) {
switch (e.orientation)
{   
    case 0:
        // Do your thing
        break;

    case -90:
        // Do your thing
        break;

    case 90:
        // Do your thing
        break;

    default:
        break;
    }
}

You may have some luck searching the PhoneGap Google Group for the term "orientation".

One example I read about as an example on how to detect orientation was Pie Guy: (game, js file). It's similar to the code you've posted, but like you... I couldn't get it to work.

One caveat: the eventListener worked for me, but I'm not sure if this is an overly intensive approach. So far it's been the only way that's worked for me, but I don't know if there are better, more streamlined ways.

UPDATE fixed the code above, it works now

Solution on windows : restarted docker

On windows I used --use-container option during sam build

So, in order to fix stuck process, I've restarted docker

The single star * unpacks the sequence/collection into positional arguments, so you can do this:

def sum(a, b):
    return a + b

values = (1, 2)

s = sum(*values)

This will unpack the tuple so that it actually executes as:

s = sum(1, 2)

The double star ** does the same, only using a dictionary and thus named arguments:

values = { 'a': 1, 'b': 2 }
s = sum(**values)

You can also combine:

def sum(a, b, c, d):
    return a + b + c + d

values1 = (1, 2)
values2 = { 'c': 10, 'd': 15 }
s = sum(*values1, **values2)

will execute as:

s = sum(1, 2, c=10, d=15)

Also see section 4.7.4 - Unpacking Argument Lists of the Python documentation.

Additionally you can define functions to take *x and **y arguments, this allows a function to accept any number of positional and/or named arguments that aren't specifically named in the declaration.

Example:

def sum(*values):
    s = 0
    for v in values:
        s = s + v
    return s

s = sum(1, 2, 3, 4, 5)

or with **:

def get_a(**values):
    return values['a']

s = get_a(a=1, b=2)      # returns 1

this can allow you to specify a large number of optional parameters without having to declare them.

And again, you can combine:

def sum(*values, **options):
    s = 0
    for i in values:
        s = s + i
    if "neg" in options:
        if options["neg"]:
            s = -s
    return s

s = sum(1, 2, 3, 4, 5)            # returns 15
s = sum(1, 2, 3, 4, 5, neg=True)  # returns -15
s = sum(1, 2, 3, 4, 5, neg=False) # returns 15

To invoke a dry run:

make -n

This will show what make is attempting to do.

Another way to throw an exceptions is assert. You can use assert to verify a condition is being fulfilled if not then it will raise AssertionError. For more details have a look here.

def avg(marks):
    assert len(marks) != 0,"List is empty."
    return sum(marks)/len(marks)

mark2 = [55,88,78,90,79]
print("Average of mark2:",avg(mark2))

mark1 = []
print("Average of mark1:",avg(mark1))

I had the same problem. I want a 100% transparent background color. Just use this code; it's worked great for me:

rgba(54, 25, 25, .00004);

You can see examples on the left side on this web page (the contact form area).

Just to add on Jacek's perfect solution. If you're trying to do this in Kotlin, it wont work immediately. Instead, you'll want to use this:

@Throws(IOException::class)
fun getSplashVideo(context: Context): File {
    val cacheFile = File(context.cacheDir, "splash_video")
    try {
        val inputStream = context.assets.open("splash_video")
        val outputStream = FileOutputStream(cacheFile)
        try {
            inputStream.copyTo(outputStream)
        } finally {
            inputStream.close()
            outputStream.close()
        }
    } catch (e: IOException) {
        throw IOException("Could not open splash_video", e)
    }
    return cacheFile
}

I do it for beamer presentations,

provide tmp-0.png through tmp-34.png

\usepackage{animate}

\begin{frame}{Torque Generating Mechanism}
  \animategraphics[loop,controls,width=\linewidth]{12}{output/tmp-}{0}{34}
\end{frame}

You shouldn't put a ListView inside a ScrollView because the ListView class implements its own scrolling and it just doesn't receive gestures because they all are handled by the parent ScrollView

Example to show last 3 digits of account number.

x = '1234567890'   
x.replace(x[:7], '')

o/p: '890'

The answers are great. If you want to give a chance to another clustering method you can use hierarchical clustering and see how data is splitting.

> set.seed(2)
> x=matrix(rnorm(50*2), ncol=2)
> hc.complete = hclust(dist(x), method="complete")
> plot(hc.complete)

Depending on how many classes you need you can cut your dendrogram as;

> cutree(hc.complete,k = 2)
 [1] 1 1 1 2 1 1 1 1 1 1 1 1 1 2 1 2 1 1 1 1 1 2 1 1 1
[26] 2 1 1 1 1 1 1 1 1 1 1 2 2 1 1 1 2 1 1 1 1 1 1 1 2

If you type ?cutree you will see the definitions. If your data set has three classes it will be simply cutree(hc.complete, k = 3). The equivalent for cutree(hc.complete,k = 2) is cutree(hc.complete,h = 4.9).

Click the arrow in the screenshot and find the bash with already running Django server. You were getting the message because your server was already running and you tried to start the server again.

[ ]{2,}

SPACE (2 or more)

You could also check that before and after those spaces words follow. (not other whitespace like tabs or new lines)

\w[ ]{2,}\w

the same, but you can also pick (capture) only the spaces for tasks like replacement

\w([ ]{2,})\w

or see that before and after spaces there is anything, not only word characters (except whitespace)

[^\s]([ ]{2,})[^\s]

On a BASH shell, you can very simply run:

export PATH=$PATH:`pwd`/somethingelse

No need to save the current working directory into a variable...

You cannot append to an existing xlsx file with xlsxwriter.

There is a module called openpyxl which allows you to read and write to preexisting excel file, but I am sure that the method to do so involves reading from the excel file, storing all the information somehow (database or arrays), and then rewriting when you call workbook.close() which will then write all of the information to your xlsx file.

Similarly, you can use a method of your own to "append" to xlsx documents. I recently had to append to a xlsx file because I had a lot of different tests in which I had GPS data coming in to a main worksheet, and then I had to append a new sheet each time a test started as well. The only way I could get around this without openpyxl was to read the excel file with xlrd and then run through the rows and columns...

i.e.

cells = []
for row in range(sheet.nrows):
    cells.append([])
    for col in range(sheet.ncols):
        cells[row].append(workbook.cell(row, col).value)

You don't need arrays, though. For example, this works perfectly fine:

import xlrd
import xlsxwriter

from os.path import expanduser
home = expanduser("~")

# this writes test data to an excel file
wb = xlsxwriter.Workbook("{}/Desktop/test.xlsx".format(home))
sheet1 = wb.add_worksheet()
for row in range(10):
    for col in range(20):
        sheet1.write(row, col, "test ({}, {})".format(row, col))
wb.close()

# open the file for reading
wbRD = xlrd.open_workbook("{}/Desktop/test.xlsx".format(home))
sheets = wbRD.sheets()

# open the same file for writing (just don't write yet)
wb = xlsxwriter.Workbook("{}/Desktop/test.xlsx".format(home))

# run through the sheets and store sheets in workbook
# this still doesn't write to the file yet
for sheet in sheets: # write data from old file
    newSheet = wb.add_worksheet(sheet.name)
    for row in range(sheet.nrows):
        for col in range(sheet.ncols):
            newSheet.write(row, col, sheet.cell(row, col).value)

for row in range(10, 20): # write NEW data
    for col in range(20):
        newSheet.write(row, col, "test ({}, {})".format(row, col))
wb.close() # THIS writes

However, I found that it was easier to read the data and store into a 2-dimensional array because I was manipulating the data and was receiving input over and over again and did not want to write to the excel file until it the test was over (which you could just as easily do with xlsxwriter since that is probably what they do anyway until you call .close()).

That's not work on optionentry because it's a "system" generated drop-down menu but you can set the padding of a select.

Just reset the box-sizing property to content-box in your CSS.

The default value of select is border-box.

select {
 box-sizing: content-box;
 padding: 5px 0;
}

This is my working variant for Laravel 7

DB::table('user')                 
  ->select('id','name')
  ->whereNotIn('id', DB::table('curses')->where('id_user', $id)->pluck('id_user')->toArray())
  ->get();

Have you tried this in your application.properties?

spring.jackson.time-zone= # Time zone used when formatting dates. For instance `America/Los_Angeles`

When you create your Sequelize object, pass false to the logging parameter:

var sequelize = new Sequelize('database', 'username', 'password', {
  
  // disable logging; default: console.log
  logging: false

});

For more options, check the docs.

Sometimes size "picks the wrong one" and returns a hash (which is what count would do)

In that case, use length to get an integer instead of hash.

The simplest answer is:

On whichever method you declare @Transactional the boundary of transaction starts and boundary ends when method completes.

If you are using JPA call then all commits are with in this transaction boundary.

Lets say you are saving entity1, entity2 and entity3. Now while saving entity3 an exception occur, then as enitiy1 and entity2 comes in same transaction so entity1 and entity2 will be rollback with entity3.

Transaction :

1. entity1.save
2. entity2.save
3. entity3.save

Any exception will result in rollback of all JPA transactions with DB.Internally JPA transaction are used by Spring.

This is where the window function row_number() comes in handy:

SELECT s.siteName, s.siteIP, h.date
FROM sites s INNER JOIN
     (select h.*, row_number() over (partition by siteName order by date desc) as seqnum
      from history h
     ) h
    ON s.siteName = h.siteName and seqnum = 1
ORDER BY s.siteName, h.date

Try this -

 select * from table where id in (3,4) or [name] in ('andy','paul');

Suppose you have 2 lists

 A = [1,2,3,4]
 B = [3,4,5,6]

so you can find A Union B as follow

 union = set(A).union(set(B))

also if you want to find intersection and non-intersection you do that as follow

 intersection = set(A).intersection(set(B))
 non_intersection = union - intersection

I personally think that sizeof(a) / sizeof(*a) looks cleaner.

I also prefer to define it as a macro:

#define NUM(a) (sizeof(a) / sizeof(*a))

Then you can use it in for-loops, thusly:

for (i = 0; i < NUM(a); i++)

I had to include "PROJECT_NAME/osdep.h" and that includes the os specific configurations.

I would look in other files using the types you are interested in and find where/how they are defined (by looking at includes).

Depends on how specific you want the test to be. You could maybe get away with

if(page_name){ string += "&page_name=" + page_name; }

If the dataframes DO NOT all have the same columns try the following:

df = pd.DataFrame.from_dict(map(dict,df_list))

We here use simply linear search. At first initialize the index equal to -1 . Then search the array , if found the assign the index value in index variable and break. Otherwise, index = -1.

   int find(int arr[], int n, int key)
   {
     int index = -1;

       for(int i=0; i<n; i++)
       {
          if(arr[i]==key)
          {
            index=i;
            break;
          }
       }
      return index;
    }


 int main()
 {
    int arr[ 5 ] = { 4, 1, 3, 2, 6 };
    int n =  sizeof(arr)/sizeof(arr[0]);
    int x = find(arr ,n, 3);
    cout<<x<<endl;
    return 0;
 }

Yes, but, didn't you parse "false"? If you parse "true", then they return true.

Maybe there's a misunderstanding: the methods don't test, if the String content represents a boolean value, they evaluate the String content to boolean.

$str = trim(preg_replace('/\s+/',' ', $str));

The above line of code will remove extra spaces, as well as leading and trailing spaces.

There is a third option: the x command, which allows you to set a different limit for the specific command instead of changing a global setting. To print the first 300 characters of a string you can use x/300s your_string. The output might be a bit harder to read. For example printing a SQL query results in:

(gdb) x/300sb stmt.c_str()
0x9cd948:    "SELECT article.r"...
0x9cd958:    "owid FROM articl"...
..

Thankfully, with C++11 there is also the more pleasing approach of using raw string literals.

printf("She said \"time flies like an arrow, but fruit flies like a banana\".");

Becomes:

printf(R"(She said "time flies like an arrow, but fruit flies like a banana".)");

With respect to the addition of brackets after the opening quote, and before the closing quote, note that they can be almost any combination of up to 16 characters, helping avoid the situation where the combination is present in the string itself. Specifically:

any member of the basic source character set except: space, the left parenthesis (, the right parenthesis ), the backslash , and the control characters representing horizontal tab, vertical tab, form feed, and newline" (N3936 §2.14.5 [lex.string] grammar) and "at most 16 characters" (§2.14.5/2)

How much clearer it makes this short strings might be debatable, but when used on longer formatted strings like HTML or JSON, it's unquestionably far clearer.

I just learned from a website:

Get-ChildItem *.txt | ForEach-Object { (get-Content $_) | Where-Object {(1) -notcontains $_.ReadCount } | Set-Content -path $_ }

Or you can use the aliases to make it short, like:

gci *.txt | % { (gc $_) | ? { (1) -notcontains $_.ReadCount } | sc -path $_ }

This code works perfectly from Spark 2.x with Scala 2.11

Import necessary classes

import org.apache.spark.sql.{Row, SparkSession}
import org.apache.spark.sql.types.{DoubleType, StringType, StructField, StructType}

Create SparkSession Object, and Here it's spark

val spark: SparkSession = SparkSession.builder.master("local").getOrCreate
val sc = spark.sparkContext // Just used to create test RDDs

Let's an RDD to make it DataFrame

val rdd = sc.parallelize(
  Seq(
    ("first", Array(2.0, 1.0, 2.1, 5.4)),
    ("test", Array(1.5, 0.5, 0.9, 3.7)),
    ("choose", Array(8.0, 2.9, 9.1, 2.5))
  )
)

Method 1

Using SparkSession.createDataFrame(RDD obj).

val dfWithoutSchema = spark.createDataFrame(rdd)

dfWithoutSchema.show()
+------+--------------------+
|    _1|                  _2|
+------+--------------------+
| first|[2.0, 1.0, 2.1, 5.4]|
|  test|[1.5, 0.5, 0.9, 3.7]|
|choose|[8.0, 2.9, 9.1, 2.5]|
+------+--------------------+

Method 2

Using SparkSession.createDataFrame(RDD obj) and specifying column names.

val dfWithSchema = spark.createDataFrame(rdd).toDF("id", "vals")

dfWithSchema.show()
+------+--------------------+
|    id|                vals|
+------+--------------------+
| first|[2.0, 1.0, 2.1, 5.4]|
|  test|[1.5, 0.5, 0.9, 3.7]|
|choose|[8.0, 2.9, 9.1, 2.5]|
+------+--------------------+

Method 3 (Actual answer to the question)

This way requires the input rdd should be of type RDD[Row].

val rowsRdd: RDD[Row] = sc.parallelize(
  Seq(
    Row("first", 2.0, 7.0),
    Row("second", 3.5, 2.5),
    Row("third", 7.0, 5.9)
  )
)

create the schema

val schema = new StructType()
  .add(StructField("id", StringType, true))
  .add(StructField("val1", DoubleType, true))
  .add(StructField("val2", DoubleType, true))

Now apply both rowsRdd and schema to createDataFrame()

val df = spark.createDataFrame(rowsRdd, schema)

df.show()
+------+----+----+
|    id|val1|val2|
+------+----+----+
| first| 2.0| 7.0|
|second| 3.5| 2.5|
| third| 7.0| 5.9|
+------+----+----+

You can also use the RestSharp library for example

var userName = "myuser";
var password = "mypassword";
var host = "170.170.170.170:333";
var client = new RestClient("https://" + host + "/method1");            
client.Authenticator = new HttpBasicAuthenticator(userName, password);            
var request = new RestRequest(Method.POST); 
request.AddHeader("Accept", "application/json");
request.AddHeader("Cache-Control", "no-cache");
request.AddHeader("Content-Type", "application/json");            
request.AddParameter("application/json","{}",ParameterType.RequestBody);
IRestResponse response = client.Execute(request);

The properties on the style object are only the styles applied directly to the element (e.g., via a style attribute or in code). So .style.marginTop will only have something in it if you have something specifically assigned to that element (not assigned via a style sheet, etc.).

To get the current calculated style of the object, you use either the currentStyle property (Microsoft) or the getComputedStyle function (pretty much everyone else).

Example:

var p = document.getElementById("target");
var style = p.currentStyle || window.getComputedStyle(p);

display("Current marginTop: " + style.marginTop);

Fair warning: What you get back may not be in pixels. For instance, if I run the above on a p element in IE9, I get back "1em".

The reason you're seeing this specific problem:

JSFiddle wraps your code in a function, so start() is not defined in the global scope.

Moral of the story: don't use inline event bindings. Use addEventListener/attachEvent.

Other notes:

Please don't pass strings to setTimeout and setInterval. It's eval in disguise.

Use a function instead, and get cozy with var and white space:

var input = document.getElementById("input"),
  add;

function start() {
  add = setInterval(function() {
    input.value++;
  }, 1000);
}

start();

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="number" id="input" />
<input type="button" onclick="clearInterval(add)" value="stop" />
<input type="button" onclick="start()" value="start" />

try to use this pipe

import { Pipe, PipeTransform } from '@angular/core';

export class ValuesPipe implements PipeTransform {
  transform(value: any, args: any[] = null): any {
    return Object.keys(value).map(key => value[key]);
  }
}

<div *ngFor="#value of object | values"> </div>

As I read your question, I have tried without success to search on the Internet how Bearer tokens are encrypted or signed. I guess bearer tokens are not hashed (maybe partially, but not completely) because in that case, it will not be possible to decrypt it and retrieve users properties from it.

But your question seems to be trying to find answers on Bearer token functionality:

Suppose I am implementing an authorization provider, can I supply any kind of string for the bearer token? Can it be a random string? Does it has to be a base64 encoding of some attributes? Should it be hashed?

So, I'll try to explain how Bearer tokens and Refresh tokens work:

When user requests to the server for a token sending user and password through SSL, the server returns two things: an Access token and a Refresh token.

An Access token is a Bearer token that you will have to add in all request headers to be authenticated as a concrete user.

Authorization: Bearer <access_token>

An Access token is an encrypted string with all User properties, Claims and Roles that you wish. (You can check that the size of a token increases if you add more roles or claims). Once the Resource Server receives an access token, it will be able to decrypt it and read these user properties. This way, the user will be validated and granted along with all the application.

Access tokens have a short expiration (ie. 30 minutes). If access tokens had a long expiration it would be a problem, because theoretically there is no possibility to revoke it. So imagine a user with a role="Admin" that changes to "User". If a user keeps the old token with role="Admin" he will be able to access till the token expiration with Admin rights. That's why access tokens have a short expiration.

But, one issue comes in mind. If an access token has short expiration, we have to send every short period the user and password. Is this secure? No, it isn't. We should avoid it. That's when Refresh tokens appear to solve this problem.

Refresh tokens are stored in DB and will have long expiration (example: 1 month).

A user can get a new Access token (when it expires, every 30 minutes for example) using a refresh token, that the user had received in the first request for a token. When an access token expires, the client must send a refresh token. If this refresh token exists in DB, the server will return to the client a new access token and another refresh token (and will replace the old refresh token by the new one).

In case a user Access token has been compromised, the refresh token of that user must be deleted from DB. This way the token will be valid only till the access token expires because when the hacker tries to get a new access token sending the refresh token, this action will be denied.

JAX-RS but you can also use regular DOM that comes with standard Java

If you want to add fields to an object dynamically, simplest way to do it is as follows:

 var params= [
{key: "k1", value=1},
{key: "k2", value=2},
{key: "k3", value=3}];

for(i=0; i< params.len; i++) {
  data[params[i].key] = params[i].value
}

This will create data object which has following fields:

{k1:1, k2:2, k3:3}

I would suggest reading some Microsoft documentation on what you can do with CSOM. This might be one example of what you are looking for, but there is a huge API documented in msdn.

// Starting with ClientContext, the constructor requires a URL to the 
// server running SharePoint. 
ClientContext context = new ClientContext("http://SiteUrl"); 

// Assume that the web has a list named "Announcements". 
List announcementsList = context.Web.Lists.GetByTitle("Announcements"); 

// Assume there is a list item with ID=1. 
ListItem listItem = announcementsList.Items.GetById(1); 

// Write a new value to the Body field of the Announcement item.
listItem["Body"] = "This is my new value!!"; 
listItem.Update(); 

context.ExecuteQuery();

SVG

Would recommend using svg for graphical elements. While using css to style your elements.

#box {_x000D_
  fill: orange;_x000D_
  stroke: black;_x000D_
}

<svg>_x000D_
  <rect id="box" x="0" y="0" width="50" height="50"/>_x000D_
</svg>

You should use Array.prototype.reduce to do this. I did do a little JS perf test to verify that this is more performant than doing a .filter + .map.

$scope.appIds = $scope.applicationsHere.reduce(function(ids, obj){
    if(obj.selected === true){
        ids.push(obj.id);
    }
    return ids;
}, []);

Just for the sake of clarity, here's the sample .reduce I used in the JSPerf test:

  var things = [_x000D_
    {id: 1, selected: true},_x000D_
    {id: 2, selected: true},_x000D_
    {id: 3, selected: true},_x000D_
    {id: 4, selected: true},_x000D_
    {id: 5, selected: false},_x000D_
    {id: 6, selected: true},_x000D_
    {id: 7, selected: false},_x000D_
    {id: 8, selected: true},_x000D_
    {id: 9, selected: false},_x000D_
    {id: 10, selected: true},_x000D_
  ];_x000D_
  _x000D_
   _x000D_
var ids = things.reduce((ids, thing) => {_x000D_
  if (thing.selected) {_x000D_
    ids.push(thing.id);_x000D_
  }_x000D_
  return ids;_x000D_
}, []);_x000D_
_x000D_
console.log(ids)

EDIT 1

Note, As of 2/2018 Reduce + Push is fastest in Chrome and Edge, but slower than Filter + Map in Firefox

Do this:

$(document).ready(function(){
    $(".header").click(function(){
        $(this).children(".children").toggle();
    });
   $(".header a").click(function(e) {
        e.stopPropagation();
   });
});

If you want to read more on .stopPropagation(), look here.

The steel is far from hot, but I combined @abatishchev's solution with the answer from this post and got to this result. Hope it's useful:

Arrays.toString is formatting the output (added the brackets and commas). you should implement your own method of toString.

public String toString(String[] arr){
    String result = "";
    for(String s : arr)
        result+=s;
    return result;
}

[edit] Stringbuilder is better though. see above.

Your task declaration is incorrectly combining the Copy task type and project.copy method, resulting in a task that has nothing to copy and thus never runs. Besides, Copy isn't the right choice for renaming a directory. There is no Gradle API for renaming, but a bit of Groovy code (leveraging Java's File API) will do. Assuming Project1 is the project directory:

task renABCToXYZ {     doLast {         file("ABC").renameTo(file("XYZ"))     } } 

Looking at the bigger picture, it's probably better to add the renaming logic (i.e. the doLast task action) to the task that produces ABC.

1. Go to Toolbar -> Settings -> Compiler
2. In the Selected compiler drop-down menu, make sure GNU GCC Compiler is selected
3. Below that, select the compiler settings tab and then the compiler flags tab underneath
4. In the list below, make sure the box for "Have g++ follow the C++11 ISO C++ language standard [-std=c++11]" is checked
5. Click OK to save

**1. Convert the json string to base64string and Write or append it to binary file. 2. Read base64string from binary file and deserialize using BsonReader. **

You can use:

for (int x = 0; x < 10; x++) {
  if (x == 5) { // If x is 5, then break it.
    break;
  }
}

I was using reactive forms and ran into similar problems. What helped me was to make sure that I set up a corresponding FormGroup in the class. Something like this:

myFormGroup: FormGroup = this.builder.group({
    dob: ['', Validators.required]
});

Okay so what helped me was iterating backwards. I was trying to remove an entry from a list but iterating upwards and it screwed up the loop because the entry didn't exist anymore:

for (int x = myList.Count - 1; x > -1; x--)
{
    myList.RemoveAt(x);
}

My hard drive in my Mac was making beeping noises in the middle of a project so I decided to install a SSD. I needed to move my project from one disk to another. A few things to consider:

• I'm vagrant w/ virtualbox on a Mac
• I'm using git

This is what worked for me:

1.) Copy your ~/.vagrant.d directory to your new machine.
2.) Copy your ~/VirtualBox\ VMs directory to your new machine. 
3.) In VirtualBox add the machines one by one using **Machine** >> **Add**
4.) Run `vagrant box list` to see if vagrant acknowledges your machines. 
5.) `git clone my_project`
6.) `vagrant up`

I had a few problems with VB Guest additions.

I fixed them with this solution.

Try this to switch to php4:

AddHandler application/x-httpd-php4 .php

Upd. Looks like I didn't understand your question correctly. This will not help if you have only php 4 on your server.

Another simple solution for dynamic textarea control.

<!--JAVASCRIPT-->
<script type="text/javascript">
$('textarea').on('input', function () {
            this.style.height = "";
            this.style.height = this.scrollHeight + "px";
 });
</script>

Update: At the time of answering this question (mid 2012, API level 14-15), setting the view programmatically was not an option (even though there were some non-trivial workarounds) whereas this has been made possible after the more recent API releases. See @Blundell's answer for details.

OLD Answer:

You cannot set a view's style programmatically yet, but you may find this thread useful.

I use Hibernate 5.2 and @Temporal is not required anymore.
java.util.date, sql.date, time.LocalDate are stored into DB with appropriate datatype as Date/timestamp.

If all you need is the ios 8 code, this should do it.

 - (BOOL)application:(UIApplication *)application       didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
       [application registerUserNotificationSettings: [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound  | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge)  categories:nil]];

       [application registerForRemoteNotifications];
}

 return YES;
}

ul {
      text-align: center;
      list-style: inside;
    }

This happened to me after I renamed a file. For some reason it was still looking for the file with the old name. What I did was create the file that it was complaining about and added to the project. Then I did a Project->clean, then Project->Build and verified the error was gone. Then I selected the newly added files and deleted them. This removed all references and I no longer see the error.

While both of the above answers work well if key,value are strings, I had a situation to append a string and integer (jq errors using the above expressions)

Minimal runnable example

The first thing that you have to know, is that the concept of NaN is implemented directly on the CPU hardware.

All major modern CPUs seem to follow IEEE 754 which specifies floating point formats, and NaNs, which are just special float values, are part of that standard.

Therefore, the concept will be the very similar across any language, including Java which just emits floating point code directly to the CPU.

Before proceeding, you might want to first read up the following answers I've written:

• a quick refresher of the IEEE 754 floating point format: What is a subnormal floating point number?
• some lower level NaN basics covered using C / C++: What is difference between quiet NaN and signaling NaN?

Now for some Java action. Most of the functions of interest that are not in the core language live inside java.lang.Float.

negative_inf   0xff800000 -Infinity
one_div_zero   0x7f800000 Infinity
log_zero       0xff800000 -Infinity

So from this we learn a few things:

• weird floating operations that don't have any sensible result give NaN:

  • 0.0f / 0.0f
  • sqrt(-1.0f)
  • log(-1.0f)

  generate a NaN.

  In C, it is actually possible to request signals to be raised on such operations with feenableexcept to detect them, but I don't think it is exposed in Java: Why does integer division by zero 1/0 give error but floating point 1/0.0 returns "Inf"?

• weird operations that are on the limit of either plus or minus infinity however do give +- infinity instead of NaN

  • 1.0f / 0.0f
  • log(0.0f)

  0.0 almost falls in this category, but likely the problem is that it could either go to plus or minus infinity, so it was left as NaN.

• if NaN is the input of a floating operation, the output also tends to be NaN

• there are several possible values for NaN 0x7fc00000, 0x7fc00001, 0x7fc00002, although x86_64 seems to generate only 0x7fc00000.

• NaN and infinity have similar binary representation.

  Let's break down a few of them:

  nan          = 0x7fc00000 = 0 11111111 10000000000000000000000
  positive_inf = 0x7f800000 = 0 11111111 00000000000000000000000
  negative_inf = 0xff800000 = 1 11111111 00000000000000000000000
                              | |        |
                              | |        mantissa
                              | exponent
                              |
                              sign
  

  From this we confirm what IEEE754 specifies:

  • both NaN and infinities have exponent == 255 (all ones)
  • infinities have mantissa == 0. There are therefore only two possible infinities: + and -, differentiated by the sign bit
  • NaN has mantissa != 0. There are therefore several possibilities, except for mantissa == 0 which is infinity

• NaNs can be either positive or negative (top bit), although it this has no effect on normal operations

json might not be the best choice for on-disk formats; The trouble it has with appending data is a good example of why this might be. Specifically, json objects have a syntax that means the whole object must be read and parsed in order to understand any part of it.

Fortunately, there are lots of other options. A particularly simple one is CSV; which is supported well by python's standard library. The biggest downside is that it only works well for text; it requires additional action on the part of the programmer to convert the values to numbers or other formats, if needed.

Another option which does not have this limitation is to use a sqlite database, which also has built-in support in python. This would probably be a bigger departure from the code you already have, but it more naturally supports the 'modify a little bit' model you are apparently trying to build.

Your repository is broken. But you can probably fix it AND keep your edits:

1. Back up first: cp your_repository your_repositry_bak
2. Clone the broken repository (still works): git clone your_repository your_repository_clone
3. Replace the broken .git folder with the one from the clone: rm -rf your_repository/.git && cp your_repository_clone/.git your_repository/ -r
4. Delete clone & backup (if everything is fine): rm -r your_repository_*

I recognize that the answer works and has been accepted but there is a much cleaner way to write that query. Tested on mysql and postgres.

To answer your main question, you want to use the subplot command. I think changing plt.figure(i) to plt.subplot(4,4,i+1) should work.

I'm not sure lookup is the right formula for this because of multiple arguments. Maybe hlookup or vlookup but these require you to have tables for values. A simple nested series of if does the trick for a small sample size

Try =IF(A1="a","pickup",IF(A1="b","collect",IF(A1="c","prepaid","")))

Now incorporate your left argument

=IF(LEFT(A1,1)="a","pickup",IF(LEFT(A1,1)="b","collect",IF(LEFT(A1,1)="c","prepaid","")))

Also note your usage of left, your argument doesn't specify the number of characters, but a set.

7/8/15 - Microsoft KB articles for the above mentioned functions. I don't think there's anything wrong with techonthenet, but I rather link to official sources.

• lookup
• hlookup
• vlookup
• if
• left

Using docker-compose, I accomplished this by creating a service that mounts the volumes that I need and committing the image of the container. Then, in the subsequent service, I rely on the previously committed image, which has all of the data stored at mounted locations. You will then have have to copy these files to their ultimate destination, as host mounted directories do not get committed when running a docker commit command

You don't have to use docker-compose to accomplish this, but it makes life a bit easier

# docker-compose.yml

version: '3'
  services:
    stage:
      image: alpine
      volumes:
        - /host/machine/path:/tmp/container/path
      command: bash -c "cp -r /tmp/container/path /final/container/path"
    setup:
      image: stage

# setup.sh

# Start "stage" service
docker-compose up stage

# Commit changes to an image named "stage"
docker commit $(docker-compose ps -q stage) stage

# Start setup service off of stage image
docker-compose up setup
