I faced the same error. Adding the tomcat server in the runtime environment will solve the error:

Right click on your project -> Properties -> Targeted runtimes -> Select apache tomcat server -> click apply -> click ok.

This sounds like a ClassLoader conflict. I'd bet you have the javax.persistence api 1.x on the classpath somewhere, whereas Spring is trying to access ValidationMode, which was only introduced in JPA 2.0.

Since you use Maven, do mvn dependency:tree, find the artifact:

<dependency>
    <groupId>javax.persistence</groupId>
    <artifactId>persistence-api</artifactId>
    <version>1.0</version>
</dependency>

And remove it from your setup. (See Excluding Dependencies)

AFAIK there is no such general distribution for JPA 2, but you can use this Hibernate-specific version:

<dependency>
    <groupId>org.hibernate.javax.persistence</groupId>
    <artifactId>hibernate-jpa-2.0-api</artifactId>
    <version>1.0.1.Final</version>
</dependency>

OK, since that doesn't work, you still seem to have some JPA-1 version in there somewhere. In a test method, add this code:

System.out.println(EntityManager.class.getProtectionDomain()
                                      .getCodeSource()
                                      .getLocation());

See where that points you and get rid of that artifact.

Ahh, now I finally see the problem. Get rid of this:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jpa</artifactId>
    <version>2.0.8</version>
</dependency>

and replace it with

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-orm</artifactId>
    <version>3.2.5.RELEASE</version>
</dependency>

On a different note, you should set all test libraries (spring-test, easymock etc.) to

<scope>test</scope>

Clean your maven cache and rerun:

mvn dependency:purge-local-repository

org.springframework.beans.factory.support.beannamegenerator , was my error. I did a maven clean, maven build etc., which was not useful and I found that my .m2 folder is not present in my eclipse installation folder. I found the .m2 folder out side of the eclipse folder which I pasted in the eclipse folder and then in eclipse I happened to do this :-

Open configure build path maven Java EE integration Select Maven archiver generates files under the build directory apply and close

My project is up and running now.

This is usually the problem with web.xml descriptor file. May be you have mixed up the annotations and web.xml servlet description definitions. Please check the console for more information.

I think it can be done per plugin. See this chapter from the Maven book.

You might be able to configure the dependency plugin to download sources (even though I haven't tried it myself :-).

You probably have something like:

"typescript":"~2.1.6"

in your package.json which npm updates to the latest minor version, in your case being 2.4.1

Edit: Question from OP

But that doesn't explain why "npm install" would change the lock file. Isn't the lock file meant to create a reproducible build? If so, regardless of the semver value, it should still use the same 2.1.6 version.

Answer:

This is intended to lock down your full dependency tree. Let's say typescript v2.4.1 requires widget ~v1.0.0. When you npm install it grabs widget v1.0.0. Later on your fellow developer (or CI build) does an npm install and gets typescript v2.4.1 but widget has been updated to widget v1.0.1. Now your node module are out of sync. This is what package-lock.json prevents.

Or more generally:

As an example, consider

package A:

{ "name": "A", "version": "0.1.0", "dependencies": { "B": "<0.1.0" } }

package B:

{ "name": "B", "version": "0.0.1", "dependencies": { "C": "<0.1.0" } }

and package C:

{ "name": "C", "version": "0.0.1" }

If these are the only versions of A, B, and C available in the registry, then a normal npm install A will install:

[email protected] -- [email protected] -- [email protected]

However, if [email protected] is published, then a fresh npm install A will install:

[email protected] -- [email protected] -- [email protected] assuming the new version did not modify B's dependencies. Of course, the new version of B could include a new version of C and any number of new dependencies. If such changes are undesirable, the author of A could specify a dependency on [email protected]. However, if A's author and B's author are not the same person, there's no way for A's author to say that he or she does not want to pull in newly published versions of C when B hasn't changed at all.

OP Question 2: So let me see if I understand correctly. What you're saying is that the lock file specifies the versions of the secondary dependencies, but still relies on the fuzzy matching of package.json to determine the top-level dependencies. Is that accurate?

Answer: No. package-lock locks the entire package tree, including the root packages described in package.json. If typescript is locked at 2.4.1 in your package-lock.json, it should remain that way until it is changed. And lets say tomorrow typescript releases version 2.4.2. If I checkout your branch and run npm install, npm will respect the lockfile and install 2.4.1.

More on package-lock.json:

package-lock.json is automatically generated for any operations where npm modifies either the node_modules tree, or package.json. It describes the exact tree that was generated, such that subsequent installs are able to generate identical trees, regardless of intermediate dependency updates.

This file is intended to be committed into source repositories, and serves various purposes:

Describe a single representation of a dependency tree such that teammates, deployments, and continuous integration are guaranteed to install exactly the same dependencies.

Provide a facility for users to "time-travel" to previous states of node_modules without having to commit the directory itself.

To facilitate greater visibility of tree changes through readable source control diffs.

And optimize the installation process by allowing npm to skip repeated metadata resolutions for previously-installed packages.

Install git on your PC and setup configuration values in either Command Prompt (cmd) or VS Code terminal (Ctrl + `)

git config --global user.name "Your Name"
git config --global user.email [email protected]

Setup editor

Windows eg.:

git config --global core.editor "'C:/Program Files/Notepad++/notepad++.exe' -multiInst -nosession"

Linux / Mac eg.:

git config --global core.editor vim

Check git settings which displays configuration details

git config --list

Login to github and create a remote repository. Copy the URL of this repository

Navigate to your project directory and execute the below commands

git init                                                           // start tracking current directory
git add -A                                                         // add all files in current directory to staging area, making them available for commit
git commit -m "commit message"                                     // commit your changes
git remote add origin https://github.com/username/repo-name.git    // add remote repository URL which contains the required details
git pull origin master                                             // always pull from remote before pushing
git push -u origin master                                          // publish changes to your remote repository

From a powershell prompt, use the gci cmdlet (alias for Get-ChildItem) and -filter option:

gci -recurse -filter "hosts"

This will return an exact match to filename "hosts".

SteveMustafa points out with current versions of powershell you can use the -File switch to give the following to recursively search for only files named "hosts" (and not directories or other miscellaneous file-system entities):

gci -recurse -filter "hosts" -File 

The commands may print many red error messages like "Access to the path 'C:\Windows\Prefetch' is denied.".

If you want to avoid the error messages then set the -ErrorAction to be silent.

gci -recurse -filter "hosts" -File -ErrorAction SilentlyContinue

An additional helper is that you can set the root to search from using -Path. The resulting command to search explicitly search from, for example, the root of the C drive would be

gci -Recurse -Filter "hosts" -File -ErrorAction SilentlyContinue -Path "C:\"

Mass file renaming via drag&drop.

Ages ago I've made a small VBScript that accepts a RegEx and replaces file names accordingly. You would simply drop a bunch of files or folders on it. I found that to be very useful throughout the years.

This was so much easier importing the registry export than what is stated above. + Simply:

1. right click on the file and
2. select "Merge"

Worked like a champ on Win 7 Pro.

Always nice to have:

Dim myPath As String     
Dim folderPath As String 

folderPath = Application.ActiveWorkbook.Path    
myPath = Application.ActiveWorkbook.FullName

Raw Javascript can accomplish the same thing pretty quickly also:

document.getElementById("myElement").onclick = function() { return false; } 

If you are using .net core 2.0 this would be:

Context.Request.Query["id"]

Sample usage:

<a href="@Url.Action("Query",new {parm1=Context.Request.Query["queryparm1"]})">GO</a>

There is no need to decompile Applet.class. The public Java API classes sourcecode comes with the JDK (if you choose to install it), and is better readable than decompiled bytecode. You can find compressed in src.zip (located in your JDK installation folder).

foo.GetColumnValues(dm.mainColumn, typeof(string))

Alternatively, you could use a generic method:

public void GetColumnValues<T>(object mainColumn)
{
    GetColumnValues(mainColumn, typeof(T));
}

and you could then use it like:

foo.GetColumnValues<string>(dm.mainColumn);

Just move the extra condition into the JOIN ON criteria, this way the existence of b is not required to return a result

SELECT a.* FROM a 
    LEFT JOIN b ON a.group_id=b.group_id AND b.user_id!=$_SESSION{['user_id']} 
    WHERE a.keyword LIKE '%".$keyword."%' 
    GROUP BY group_id

    $file = '../image.jpg';
    $type = 'image/jpeg';
    header('Content-Type:'.$type);
    header('Content-Length: ' . filesize($file));
    $img = file_get_contents($file);
    echo $img;

This is works for me! I have test it on code igniter. if i use readfile, the image won't display. Sometimes only display jpg, sometimes only big file. But after i changed it to "file_get_contents" , I get the flavour, and works!! this is the screenshoot: Screenshot of "secure image" from database

I came across the same nagging error, which I realized has something to do with a cool feature PyCharm automatically detects...just add the @staticmethod decorator, and it will automatically remove that error where the method is used

The most important difference is that robocopy will (usually) retry when an error occurs, while xcopy will not. In most cases, that makes robocopy far more suitable for use in a script.

Addendum: for completeness, there is one known edge case issue with robocopy; it may silently fail to copy files or directories whose names contain invalid UTF-16 sequences. If that's a problem for you, you may need to look at third-party tools, or write your own.

1. Rename the .env.example to .env
2. Go to bootstrap=>app.php and uncomment $app->withEloquent();
3. Make sure that APP_DEBUG=true in .env file. Now it will work.

var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top;   
if (!isNaN(top)) {
$("#app_scroler").click(function () {   
$('html, body').animate({
            scrollTop: top
        }, 100);
    });
}

if you want to scroll a little above or below from specific div that add value to the top like this.....like I add 800

var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top + 800;

You can do this by changing the php.ini file and add the following

display_errors = on
display_startup_errors = on

OR you can also use the following code as this always works for me

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

Another tool you can use is registry-cli. For example, this command:

registry.py -l "login:password" -r https://your-registry.example.com --delete

will delete all but the last 10 images.

To solve this problem, you may need to repair your SQL Server 2005

Simple steps can be

1. Update/Install .Net 2.0 framework. Windows Installer 3.1 available online recommended
2. Download the setup files from Microsoft website : http://www.microsoft.com/en-in/download/details.aspx?id=184
3. Follow the steps mentioned below from the Symantec website: http://www.symantec.com/connect/articles/install-and-configure-sql-server-2005-express

Hope this helps!

If you are on macOS Catalina, the new default shell is zsh. You will need to run source /bin/activate followed by conda init zsh. For example: I installed anaconda python 3.7 Version, type echo $USER to find username

source /Users/my_username/opt/anaconda3/bin/activate

Follow by

conda init zsh

or (for bash shell)

conda init

Check working:

conda list

The error will be fixed.

For those doing video I cobbled the following based on @tsh :

import cv2 as cv
import numpy as np

def nothing(x):pass

cap = cv.VideoCapture(0)
cv.namedWindow('videoUI', cv.WINDOW_NORMAL)
cv.createTrackbar('T','videoUI',0,255,nothing)

while(True):
    ret, frame = cap.read()
    vid_gray = cv.cvtColor(frame, cv.COLOR_BGR2GRAY)
    thresh = cv.getTrackbarPos('T','videoUI');
    vid_bw = cv.threshold(vid_gray, thresh, 255, cv.THRESH_BINARY)[1]

    cv.imshow('videoUI',cv.flip(vid_bw,1))

    if cv.waitKey(1) & 0xFF == ord('q'):
        break

cap.release()
cv.destroyAllWindows()

Results in:

To check if a string does not contain any whitespaces, you can use

string.matches("^\\S*$")

Example:

"name"        -> true
"  "          -> false
"name xxname" -> false

jQuery's CSS manipulation isn't queued, but you can make it executed inside the 'fx' queue by doing:

$('#div').delay(1000).queue('fx', function() { $(this).removeClass('error'); });

Quite same thing as calling setTimeout but uses jQuery's queue mecanism instead.

You can use cloudsync to keep a folder in-sync with a remote:

pip install cloudsync
pip install cloudsync-gdrive
cloudsync sync file:c:/users/me/documents gdrive:/mydocs

If the remote is NFS, you can use:

cloudsync sync file:c:/users/me/documents/ file:/mnt/nfs/whatevs

If you used the auth scaffolding in 5.5 simply direct your href to:

{{ route('logout') }}

There is no need to alter any routes or controllers.

So I did some tests with sqlite for very large files, and came to some conclusions (at least for my specific application).

The tests involve a single sqlite file with either a single table, or multiple tables. Each table had about 8 columns, almost all integers, and 4 indices.

The idea was to insert enough data until sqlite files were about 50GB.

Single Table

I tried to insert multiple rows into a sqlite file with just one table. When the file was about 7GB (sorry I can't be specific about row counts) insertions were taking far too long. I had estimated that my test to insert all my data would take 24 hours or so, but it did not complete even after 48 hours.

This leads me to conclude that a single, very large sqlite table will have issues with insertions, and probably other operations as well.

I guess this is no surprise, as the table gets larger, inserting and updating all the indices take longer.

Multiple Tables

I then tried splitting the data by time over several tables, one table per day. The data for the original 1 table was split to ~700 tables.

This setup had no problems with the insertion, it did not take longer as time progressed, since a new table was created for every day.

Vacuum Issues

As pointed out by i_like_caffeine, the VACUUM command is a problem the larger the sqlite file is. As more inserts/deletes are done, the fragmentation of the file on disk will get worse, so the goal is to periodically VACUUM to optimize the file and recover file space.

However, as pointed out by documentation, a full copy of the database is made to do a vacuum, taking a very long time to complete. So, the smaller the database, the faster this operation will finish.

Conclusions

For my specific application, I'll probably be splitting out data over several db files, one per day, to get the best of both vacuum performance and insertion/delete speed.

This complicates queries, but for me, it's a worthwhile tradeoff to be able to index this much data. An additional advantage is that I can just delete a whole db file to drop a day's worth of data (a common operation for my application).

I'd probably have to monitor table size per file as well to see when the speed will become a problem.

It's too bad that there doesn't seem to be an incremental vacuum method other than auto vacuum. I can't use it because my goal for vacuum is to defragment the file (file space isn't a big deal), which auto vacuum does not do. In fact, documentation states it may make fragmentation worse, so I have to resort to periodically doing a full vacuum on the file.

You can use cookies if the data is small enough and does not present a security concern. The same HttpContext.Current based approach should work.

Request and response HTTP headers can also be used to pass information between service calls.

NSDate and the timeIntervalSince* methods will return a NSTimeInterval which is a double with sub-millisecond accuracy. NSTimeInterval is in seconds, but it uses the double to give you greater precision.

In order to calculate millisecond time accuracy, you can do:

// Get a current time for where you want to start measuring from
NSDate *date = [NSDate date];

// do work...

// Find elapsed time and convert to milliseconds
// Use (-) modifier to conversion since receiver is earlier than now
double timePassed_ms = [date timeIntervalSinceNow] * -1000.0;

Documentation on timeIntervalSinceNow.

There are many other ways to calculate this interval using NSDate, and I would recommend looking at the class documentation for NSDate which is found in NSDate Class Reference.

You are looking for the the MySQL functions FROM_UNIXTIME() and UNIX_TIMESTAMP().

Use them in your SQL, e.g.:

mysql> SELECT UNIX_TIMESTAMP(NOW());
+-----------------------+
| UNIX_TIMESTAMP(NOW()) |
+-----------------------+
|            1311343579 |
+-----------------------+
1 row in set (0.00 sec)

mysql> SELECT FROM_UNIXTIME(1311343579);
+---------------------------+
| FROM_UNIXTIME(1311343579) |
+---------------------------+
| 2011-07-22 15:06:19       |
+---------------------------+
1 row in set (0.00 sec)

Try this:

[^a-zA-Z0-9 :]

JavaScript example:

"!@#$%* ABC def:123".replace(/[^a-zA-Z0-9 :]/g, ".")

According to the source code located here, starting at line 850, PostgreSQL doesn't explicitly limit the number of arguments.

The following is a code comment from line 870:

/*
 * We try to generate a ScalarArrayOpExpr from IN/NOT IN, but this is only
 * possible if the inputs are all scalars (no RowExprs) and there is a
 * suitable array type available.  If not, we fall back to a boolean
 * condition tree with multiple copies of the lefthand expression.
 * Also, any IN-list items that contain Vars are handled as separate
 * boolean conditions, because that gives the planner more scope for
 * optimization on such clauses.
 *
 * First step: transform all the inputs, and detect whether any are
 * RowExprs or contain Vars.

In theory, there's nothing preventing you from sending a request body in a GET request. The HTTP protocol allows it, but have no defined semantics, so it's up to you to document what exactly is going to happen when a client sends a GET payload. For instance, you have to define if parameters in a JSON body are equivalent to querystring parameters or something else entirely.

However, since there are no clearly defined semantics, you have no guarantee that implementations between your application and the client will respect it. A server or proxy might reject the whole request, or ignore the body, or anything else. The REST way to deal with broken implementations is to circumvent it in a way that's decoupled from your application, so I'd say you have two options that can be considered best practices.

The simple option is to use POST instead of GET as recommended by other answers. Since POST is not standardized by HTTP, you'll have to document how exactly that's supposed to work.

Another option, which I prefer, is to implement your application assuming the GET payload is never tampered with. Then, in case something has a broken implementation, you allow clients to override the HTTP method with the X-HTTP-Method-Override, which is a popular convention for clients to emulate HTTP methods with POST. So, if a client has a broken implementation, it can write the GET request as a POST, sending the X-HTTP-Method-Override: GET method, and you can have a middleware that's decoupled from your application implementation and rewrites the method accordingly. This is the best option if you're a purist.

Here's what you can do for say yyyy-mm-dd comparison:

GregorianCalendar gc= new GregorianCalendar();
gc.setTimeInMillis(System.currentTimeMillis());
gc.roll(GregorianCalendar.DAY_OF_MONTH, true);

Date d1 = new Date();
Date d2 = gc.getTime();

SimpleDateFormat sf= new SimpleDateFormat("yyyy-MM-dd");

if(sf.format(d2).hashCode() < sf.format(d1).hashCode())
{
    System.out.println("date 2 is less than date 1");
}
else
{
    System.out.println("date 2 is equal or greater than date 1");
}

The export default {...} construction is just a shortcut for something like this:

const funcs = {
    foo() { console.log('foo') }, 
    bar() { console.log('bar') },
    baz() { foo(); bar() }
}

export default funcs

It must become obvious now that there are no foo, bar or baz functions in the module's scope. But there is an object named funcs (though in reality it has no name) that contains these functions as its properties and which will become the module's default export.

So, to fix your code, re-write it without using the shortcut and refer to foo and bar as properties of funcs:

const funcs = {
    foo() { console.log('foo') }, 
    bar() { console.log('bar') },
    baz() { funcs.foo(); funcs.bar() } // here is the fix
}

export default funcs

Another option is to use this keyword to refer to funcs object without having to declare it explicitly, as @pawel has pointed out.

Yet another option (and the one which I generally prefer) is to declare these functions in the module scope. This allows to refer to them directly:

function foo() { console.log('foo') }
function bar() { console.log('bar') }
function baz() { foo(); bar() }

export default {foo, bar, baz}

And if you want the convenience of default export and ability to import items individually, you can also export all functions individually:

// util.js

export function foo() { console.log('foo') }
export function bar() { console.log('bar') }
export function baz() { foo(); bar() }

export default {foo, bar, baz}

// a.js, using default export

import util from './util'
util.foo()

// b.js, using named exports

import {bar} from './util'
bar()

Or, as @loganfsmyth suggested, you can do without default export and just use import * as util from './util' to get all named exports in one object.

I had the same problem but was able to fix it by doing the following:

Right-click on the project -> Properties, then add the JAR (odjbc6 or 14) file in the deployment assembly.

@vigilante_stark's answer worked for me. It can be used to set a minimum "approximately" fixed margin in pixels. But in a responsive layout, when the width of the page is increasing margin can be increased by a percentage according to the given percentage as well. I used it as follows

example-class{
  margin: 0 calc(20px + 5%) 0 0;
}

Menu Tools ? Options ? Package Manager

Give a name and folder location. Click OK. Drop your NuGet package files in that folder.

Go to your Project, right click and select "Manage NuGet Packages" and select your new package source.

Here is the documentation.

You can use a JavaScript library such as JXtension which gives the user the ability to make a color lighter or darker. If you would like to find documentation for this brand new library, click here. You can also use JXtension to combine one color with another.

Simple command to check keras version:

(py36) C:\WINDOWS\system32>python
Python 3.6.8 |Anaconda custom (64-bit) 

>>> import keras
Using TensorFlow backend.
>>> keras.__version__
'2.2.4'

Did you import the packages for the file reading stuff.

import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.InputStreamReader;

also here

cfiltering(numberOfUsers, numberOfMovies);

Are you trying to create an object or calling a method?

also another thing:

user_movie_matrix[userNo][movieNo]=rating;

you are assigning a value to a member of an instance as if it was a static variable also remove the Th in

private int user_movie_matrix[][];Th

Hope this helps.

Android kotlin, hide or set visibility of a menu item in the action bar programmatically.

override fun onCreateOptionsMenu(menu: Menu): Boolean {
    val inflater = menuInflater
    inflater.inflate(R.menu.main_menu, menu)
    val method = menu.findItem(R.id.menu_method)
    method.isVisible = false //if want to show set true
    return super.onCreateOptionsMenu(menu)
}

Your null pointer exception seems to be on this line:

String url = intent.getExtras().getString("userurl");

because intent.getExtras() returns null when the intent doesn't have any extras.

You have to realize that this piece of code:

Intent Main = new Intent(this, ToClass.class);
Main.putExtra("userurl", url);
startActivity(Main);

doesn't start the activity you wrote in Main.java, it will attempt to start an activity called ToClass and if that doesn't exist, your app crashes.

Also, there is no such thing as "android.intent.action.start" so the manifest should look more like:

<activity android:name=".start" android:label="@string/app_name">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
<activity android:name= ".Main">
</activity>

I hope this fixes some of the issues you are encountering but I strongly suggest you check out some "getting started" tutorials for android development and build up from there.

This answer is for XAMPP on Ubuntu.

The manual for installation and download is on (site official)

http://www.apachefriends.org/it/xampp-linux.html

After to start XAMPP simply call this command:

sudo /opt/lampp/lampp start

You should now see something like this on your screen:

Starting XAMPP 1.8.1...
LAMPP: Starting Apache...
LAMPP: Starting MySQL...
LAMPP started.

If you have this

Starting XAMPP for Linux 1.8.1...                                                             
XAMPP: Another web server daemon is already running.                                          
XAMPP: Another MySQL daemon is already running.                                               
XAMPP: Starting ProFTPD...                                                                    
XAMPP for Linux started

. The solution is

sudo /etc/init.d/apache2 stop
sudo /etc/init.d/mysql stop

And the restast with sudo //opt/lampp/lampp restart

You to fix most of the security weaknesses simply call the following command:

/opt/lampp/lampp security

After the change this file

sudo kate //opt/lampp/etc/extra/httpd-xampp.conf

Find and replace on

    #
# New XAMPP security concept
#

You can replace hash with null

var urlWithoutHash = document.location.href.replace(location.hash , "" );

public string CreateThumbnail(int maxWidth, int maxHeight, string path)
{

    var image = System.Drawing.Image.FromFile(path);
    var ratioX = (double)maxWidth / image.Width;
    var ratioY = (double)maxHeight / image.Height;
    var ratio = Math.Min(ratioX, ratioY);
    var newWidth = (int)(image.Width * ratio);
    var newHeight = (int)(image.Height * ratio);
    var newImage = new Bitmap(newWidth, newHeight);
    Graphics thumbGraph = Graphics.FromImage(newImage);

    thumbGraph.CompositingQuality = CompositingQuality.HighQuality;
    thumbGraph.SmoothingMode = SmoothingMode.HighQuality;
    //thumbGraph.InterpolationMode = InterpolationMode.HighQualityBicubic;

    thumbGraph.DrawImage(image, 0, 0, newWidth, newHeight);
    image.Dispose();

    string fileRelativePath = "newsizeimages/" + maxWidth + Path.GetFileName(path);
    newImage.Save(Server.MapPath(fileRelativePath), newImage.RawFormat);
    return fileRelativePath;
}

You should use <span>, because as specified by the spec, <font> has been deprecated and probably won't display as you intend.

If you want to create a new input field with for example file type:

 // Create a new Input with type file and id='file-input'
 var newFileInput = document.createElement('input');

 // The new input file will have type 'file'
 newFileInput.type = "file";

 // The new input file will have class="w-95 mb-1" (width - 95%, margin-bottom: .25rem)
 newFileInput.className = "w-95 mb-1"

The output will be: <input type="file" class="w-95 mb-1">

If you want to create a nested tag using JavaScript, the simplest way is with innerHtml:

var tag = document.createElement("li");
tag.innerHTML = '<span class="toggle">Jan</span>';

The output will be:

<li>
    <span class="toggle">Jan</span>
</li>

So, this question comes up first if you search for "Implement binomial coefficients in Python". Only this answer in its second part contains an efficient implementation which relies on the multiplicative formula. This formula performs the bare minimum number of multiplications. The function below does not depend on any built-ins or imports:

def fcomb0(n, k):
    '''
    Compute the number of ways to choose $k$ elements out of a pile of $n.$

    Use an iterative approach with the multiplicative formula:
    $$\frac{n!}{k!(n - k)!} =
    \frac{n(n - 1)\dots(n - k + 1)}{k(k-1)\dots(1)} =
    \prod_{i = 1}^{k}\frac{n + 1 - i}{i}$$

    Also rely on the symmetry: $C_n^k = C_n^{n - k},$ so the product can
    be calculated up to $\min(k, n - k).$

    :param n: the size of the pile of elements
    :param k: the number of elements to take from the pile
    :return: the number of ways to choose k elements out of a pile of n
    '''

    # When k out of sensible range, should probably throw an exception.
    # For compatibility with scipy.special.{comb, binom} returns 0 instead.
    if k < 0 or k > n:
        return 0

    if k == 0 or k == n:
        return 1

    total_ways = 1
    for i in range(min(k, n - k)):
        total_ways = total_ways * (n - i) // (i + 1)

    return total_ways

Finally, if you need even larger values and do not mind trading some accuracy, Stirling's approximation is probably the way to go.

If the list implementation you're using is IEnumerable<T> and Linq is an option, you can use Any:

if (!list.Any()) {

}

Otherwise you generally have a Length or Count property on arrays and collection types respectively.

Here is a very simple piece of C# code to test the CommandTimeout with. It creates a new command which will wait for 2 seconds. Set the CommandTimeout to 1 second and you will see an exception when running it. Setting the CommandTimeout to either 0 or something higher than 2 will run fine. By the way, the default CommandTimeout is 30 seconds.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using System.Data.SqlClient;

namespace ConsoleApplication1
{
  class Program
  {
    static void Main(string[] args)
    {
      var builder = new SqlConnectionStringBuilder();
      builder.DataSource = "localhost";
      builder.IntegratedSecurity = true;
      builder.InitialCatalog = "master";

      var connectionString = builder.ConnectionString;

      using (var connection = new SqlConnection(connectionString))
      {
        connection.Open();

        using (var command = connection.CreateCommand())
        {
          command.CommandText = "WAITFOR DELAY '00:00:02'";
          command.CommandTimeout = 1;

          command.ExecuteNonQuery();
        }
      }

I'd like to say technically yes, since really what gets rendered is technically always browser dependent. Most browsers try to keep to the specifications as best they can and as far as I know there is nothing in the css specifications against it. I'm only going to vouch for the actual html,css,javascript code that gets sent to the browser before any other interpretter steps in.

However I also say no since every browser I typically test on doesn't actually let you. If you need to see for yourself save the following as a .html file and open it up in the major browsers. In all browsers I tested on the javascript function will not match to an element. However, remove either "hunkojunk" from the id tag and all works fine. Sample Code

<html>
<head>
</head>
<body>
    <p id="hunkojunk1 hunkojunk2"></p>

<script type="text/javascript">
    document.getElementById('hunkojunk2').innerHTML = "JUNK JUNK JUNK JUNK JUNK JUNK";
</script>
</body>
</html>

You can just add a new key to the instance by the following command:

ssh-copy-id -i ~/.ssh/id_rsa.pub domain_alias

You can configure domain_alias in ~/.ssh config

host domain_alias
  User ubuntu
  Hostname domain.com
  IdentityFile ~/.ssh/ec2.pem

For anyone who is looking a way to watch a specific file to exist in VBS:

Function bIsFileDownloaded(strPath, timeout)
  Dim FSO, fileIsDownloaded
  set FSO = CreateObject("Scripting.FileSystemObject")
  fileIsDownloaded = false
  limit = DateAdd("s", timeout, Now)
  Do While Now < limit
    If FSO.FileExists(strPath) Then : fileIsDownloaded = True : Exit Do : End If
    WScript.Sleep 1000      
  Loop
  Set FSO = Nothing
  bIsFileDownloaded = fileIsDownloaded
End Function

Usage:

FileName = "C:\test.txt"
fileIsDownloaded = bIsFileDownloaded(FileName, 5) ' keep watching for 5 seconds

If fileIsDownloaded Then
  WScript.Echo Now & " File is Downloaded: " & FileName
Else
  WScript.Echo Now & " Timeout, file not found: " & FileName 
End If

Fool proof method (no RegEx and Ctrl+Enter didn't work for me as it was just jumping to next Find):

First, select an occurrence of \n and hit Ctrl+H (brings up the Replace... dialogue, also accessible through Find -> Replace... menu). This populates the Find what field.

Go to the end of any line of your file (press End if your keyboard has it) and select the end of line by holding down Shift and pressing ? (right arrow) EXACTLY once. Then copy-paste this into the Replace with field.

(the animation is for finding true new lines; works the same for replacing them)

I tried this regex for parsing url partitions:

^((http[s]?|ftp):\/)?\/?([^:\/\s]+)(:([^\/]*))?((\/?(?:[^\/\?#]+\/+)*)([^\?#]*))(\?([^#]*))?(#(.*))?$

URL: https://www.google.com/my/path/sample/asd-dsa/this?key1=value1&key2=value2

Matches:

Group 1.    0-7 https:/
Group 2.    0-5 https
Group 3.    8-22    www.google.com
Group 6.    22-50   /my/path/sample/asd-dsa/this
Group 7.    22-46   /my/path/sample/asd-dsa/
Group 8.    46-50   this
Group 9.    50-74   ?key1=value1&key2=value2
Group 10.   51-74   key1=value1&key2=value2

Would the following Macro help you?

Sub activateSheet(sheetname As String)
'activates sheet of specific name
    Worksheets(sheetname).Activate
End Sub

Basically you want to make use of the .Activate function. Or you can use the .Select function like so:

Sub activateSheet(sheetname As String)
'selects sheet of specific name
    Sheets(sheetname).Select
End Sub

The functional way of achieving this is to unzip the list using:

sample = [(2, 9), (2, 9), (8, 9), (10, 9), (23, 26), (1, 9), (43, 44)]
first,snd = zip(*sample)
print(first,snd)

(2, 2, 8, 10, 23, 1, 43) (9, 9, 9, 9, 26, 9, 44)

You can use getElementsByTagName function, it returns a HTMLCollection of elements with the given tag name.

var elements = document.getElementsByTagName("input")
for (var i = 0; i < elements.length; i++) {
    if(elements[i].value == "") {
        alert('empty');
        //Do something here
    }
}

DEMO

You can also use document.myform.getElementsByTagName provided you have given a name to yoy form

DEMO with form Name

You need to define the button text and have valid HTML for the button. I would also suggest using .on for the click handler of the button

$(function () {_x000D_
  $('#Add').on('click', function () {_x000D_
    $('<p>Text</p>').appendTo('#Content');_x000D_
  });_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<div id="Content">_x000D_
    <button id="Add">Add Text</button>_x000D_
</div>

Also I would make sure the jquery is at the bottom of the page just before the closing </body> tag. Doing so will make it so you do not have to have the whole thing wrapped in $(function but I would still do that. Having your javascript load at the end of the page makes it so the rest of the page loads incase there is a slow down in your javascript somewhere.

You can also use a class object directly; it creates a namespace:

class a: pass
a.somefield1 = 'somevalue1'
setattr(a, 'somefield2', 'somevalue2')

Both time and datetime have a date component.

Normally if you are just dealing with the time part you'd supply a default date. If you are just interested in the difference and know that both times are on the same day then construct a datetime for each with the day set to today and subtract the start from the stop time to get the interval (timedelta).

Very late answer, but I think my answer is more straight forward for specific use cases where users want to simply insert (copy) data from table A into table B:

INSERT INTO table_b (col1, col2, col3, col4, col5, col6)
SELECT col1, 'str_val', int_val, col4, col5, col6
FROM table_a

def reverse(text):
    reversed = ''
    for i in range(len(text)-1, -1, -1):
        reversed += text[i]
    return reversed

print("reverse({}): {}".format("abcd", reverse("abcd")))

This is a trick,

function openInNewTab(url) {
  var win = window.open(url, '_blank');
  win.focus();
}

In most cases, this should happen directly in the onclick handler for the link to prevent pop-up blockers, and the default "new window" behavior. You could do it this way, or by adding an event listener to your DOM object.

<div onclick="openInNewTab('www.test.com');">Something To Click On</div>

Sitepoint: Disable back for Javascript

event.stopPropagation() and event.preventDefault() do nothing in IE. I had to send return event.keyCode == 11 (I just picked something) instead of just saying "if not = 8, run the event" to make it work, though. event.returnValue = false also works.

A different approach ... here is an example: If the user has a delay of 600-1000ms when is typing you may consider he's stopped.

Here is a newer way of how to turn a Console Application to a Windows Service as a Worker Service based on the latest .Net Core 3.1.

If you create a Worker Service from Visual Studio 2019 it will give you almost everything you need for creating a Windows Service out of the box, which is also what you need to change to the console application in order to convert it to a Windows Service.

Here are the changes you need to do:

Install the following NuGet packages

Install-Package Microsoft.Extensions.Hosting.WindowsServices -Version 3.1.0
Install-Package Microsoft.Extensions.Configuration.Abstractions -Version 3.1.0

Change Program.cs to have an implementation like below:

using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

namespace ConsoleApp
{
    class Program
    {
        public static void Main(string[] args)
        {
            CreateHostBuilder(args).UseWindowsService().Build().Run();
        }

        private static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureServices((hostContext, services) =>
                {
                    services.AddHostedService<Worker>();
                });
    }
}

and add Worker.cs where you will put the code which will be run by the service operations:

using Microsoft.Extensions.Hosting;
using System.Threading;
using System.Threading.Tasks;

namespace ConsoleApp
{
    public class Worker : BackgroundService
    {
        protected override async Task ExecuteAsync(CancellationToken stoppingToken)
        {
            //do some operation
        }

        public override Task StartAsync(CancellationToken cancellationToken)
        {
            return base.StartAsync(cancellationToken);
        }

        public override Task StopAsync(CancellationToken cancellationToken)
        {
            return base.StopAsync(cancellationToken);
        }
    }
}

When everything is ready, and the application has built successfully, you can use sc.exe to install your console application exe as a Windows Service with the following command:

sc.exe create DemoService binpath= "path/to/your/file.exe"

You can use this library on git for this purpose https://github.com/ehynds/jquery-ui-multiselect-widget

for initiating the selectbox use this

    $("#selectBoxId").multiselect().multiselectfilter();

and when you have the data ready in json (from ajax or any method), first parse the data & then assign the js array to it

    var js_arr = $.parseJSON(/*data from ajax*/);
    $("#selectBoxId").val(js_arr);
    $("#selectBoxId").multiselect("refresh");

Unless I'm misunderstanding, you lost your .ssh directory containing your private key on your local machine and so you want to remove the public key which was on a server and which allowed key-based login.

In that case, it will be stored in the .ssh/authorized_keys file in your home directory on the server. You can just edit this file with a text editor and delete the relevant line if you can identify it (even easier if it's the only entry!).

I hope that key wasn't your only method of access to the server and you have some other way of logging in and editing the file. You can either manually add a new public key to authorised_keys file or use ssh-copy-id. Either way, you'll need password authentication set up for your account on the server, or some other identity or access method to get to the authorized_keys file on the server.

ssh-add adds identities to your SSH agent which handles management of your identities locally and "the connection to the agent is forwarded over SSH remote logins, and the user can thus use the privileges given by the identities anywhere in the network in a secure way." (man page), so I don't think it's what you want in this case. It doesn't have any way to get your public key onto a server without you having access to said server via an SSH login as far as I know.

First, I think you're calling it the wrong thing. "JSON" stands for "JavaScript Object Notation" - it's just a specification for representing some data in a string that explicitly mimics JavaScript object (and array, string, number and boolean) literals. You're trying to build up a JavaScript object dynamically - so the word you're looking for is "object".

With that pedantry out of the way, I think that you're asking how to set object and array properties.

// make an empty object
var myObject = {};

// set the "list1" property to an array of strings
myObject.list1 = ['1', '2'];

// you can also access properties by string
myObject['list2'] = [];
// accessing arrays is the same, but the keys are numbers
myObject.list2[0] = 'a';
myObject['list2'][1] = 'b';

myObject.list3 = [];
// instead of placing properties at specific indices, you
// can push them on to the end
myObject.list3.push({});
// or unshift them on to the beginning
myObject.list3.unshift({});
myObject.list3[0]['key1'] = 'value1';
myObject.list3[1]['key2'] = 'value2';

myObject.not_a_list = '11';

That code will build up the object that you specified in your question (except that I call it myObject instead of myJSON). For more information on accessing properties, I recommend the Mozilla JavaScript Guide and the book JavaScript: The Good Parts.

Copy all file and replace to /var/lib/mysql , after that you must change owner of files to mysql this is so important if mariadb.service restart has been faild

chown -R mysql:mysql /var/lib/mysql/*

and

chmod -R 700 /var/lib/mysql/*

Get simple name instead of path.

String onlyClassName =  this.getLocalClassName(); 

call above method in onCreate

Preferences -> General -> Load preferences from a custom folder or URL

First time you choose this, it will automatically save a preferences file into this folder called "com.googlecode.iterm2.plist"

The Main method is static inside the Program class. You can't call an instance method from inside a static method, which is why you're getting the error.

To fix it you just need to make your GetRandomBits() method static as well.

A bit more detail to Joachim Sauer's answer:

On Ubuntu at least, the metapackage tomcat6 depends on metapackage tomcat6-common (and others), which depends on metapackage libtomcat6-java, which depends on package libservlet2.5-java (and others). It contains, among others, the files /usr/share/java/servlet-api-2.5.jar and /usr/share/java/jsp-api-2.1.jar, which are the servlet and JSP libraries you need. So if you've installed Tomcat 6 through apt-get or the Ubuntu Software Centre, you already have the libraries; all that's left is to get Tomcat to use them in your project.

Place libraries /usr/share/java/servlet-api-2.5.jar and /usr/share/java/jsp-api-2.1.jar on the class path like this:

• For all projects, by configuring Eclipse by selecting Window -> Preferences -> Java -> Installed JREs, then selecting the JRE you're using, pressing Edit, then pressing Add External JARs, and then by selecting the files from the locations given above.

• For just one project, by right-clicking on the project in the Project Explorer pane, then selecting Properties -> Java Build Path, and then pressing Add External JARs, and then by selecting the files from the locations given above.

Further note 1: These are the correct versions of those libraries for use with Tomcat 6; for the other Tomcat versions, see the table on page http://tomcat.apache.org/whichversion.html, though I would suppose each Tomcat version includes the versions of these libraries that are appropriate for it.

Further note 2: Package libservlet2.5-java's description (dpkg-query -s libservlet2.5-java) says: 'Apache Tomcat implements the Java Servlet and the JavaServer Pages (JSP) specifications from Sun Microsystems, and provides a "pure Java" HTTP web server environment for Java code to run. This package contains the Java Servlet and JSP library.'

Update - the answer below was written before C# 6 came along. In C# 6 you can write:

public class Foo
{
    public string Bar { get; set; } = "bar";
}

You can also write read-only automatically-implemented properties, which are only writable in the constructor (but can also be given a default initial value):

public class Foo
{
    public string Bar { get; }

    public Foo(string bar)
    {
        Bar = bar;
    }
}

It's unfortunate that there's no way of doing this right now. You have to set the value in the constructor. (Using constructor chaining can help to avoid duplication.)

Automatically implemented properties are handy right now, but could certainly be nicer. I don't find myself wanting this sort of initialization as often as a read-only automatically implemented property which could only be set in the constructor and would be backed by a read-only field.

This hasn't happened up until and including C# 5, but is being planned for C# 6 - both in terms of allowing initialization at the point of declaration, and allowing for read-only automatically implemented properties to be initialized in a constructor body.

This will display the path, filename and the content line it found that matched the pattern.

Get-ChildItem -Path d:\applications\*config -recurse |  Select-String -Pattern "dummy" 

Try this:

tar -czf my.tar.gz dir/

But are you sure you are not compressing some .exe file or something? Maybe the problem is not with te compression, but with the files you are compressing?

You can also use border-style: double with background-clip: padding-box, without the use of any extra (pseudo-)elements. It's probably the most compact solution, but not as flexible as the others.

For example:

<div class="circle">Some text goes here...</div>

.circle{
    width: 100px;
    height: 100px;
    padding: 50px;
    border-radius: 200px;
    border: double 15px rgba(255,255,255,0.7);
    background: rgba(255,255,255,0.7);
    background-clip: padding-box;
}

If you look closely you can see that the edge between the border and the background is not perfect. This seems to be an issue in current browsers. But it's not that noticeable when the border is small.

Here is the easiest solution.

There are a lot of environment special configurations needed if you are using Maven. So, if you start your program from maven, just run the mvnDebug command instead of mvn, it will take care of starting your app with remote debugging configurated. Now you can just attach a debugger on port 8000.

It'll take care of all the environment problems for you.

This is more a footnote to a number of the answers above which suggest the use of ON DUPLICATE KEY UPDATE, BEWARE that this is NOT always replication safe, so if you ever plan on growing beyond a single server, you'll want to avoid this and use two queries, one to verify the existence, and then a second to either UPDATE when a row exists, or INSERT when it does not.

I was having a problem getting my ASP.NET 5.0/MVC 6 app to serve static binary file types or browse virtual directories. It looks like this is now done in Configure() at startup. See http://docs.asp.net/en/latest/fundamentals/static-files.html for a quick primer.

If you want to clone into the current folder, you should try this:

git clone https://github.com/example/example.git ./

The @japf answer above is working fine and in my case I wanted to change the mouse cursor from a Spinning Wheel back to the normal Arrow once the CEF Browser finished loading the page. In case it can help someone, here is the code:

private void Browser_LoadingStateChanged(object sender, CefSharp.LoadingStateChangedEventArgs e) {
   if (!e.IsLoading) {
      // set the cursor back to arrow
      Application.Current.Dispatcher.BeginInvoke(DispatcherPriority.Background,
         new Action(() => Mouse.OverrideCursor = Cursors.Arrow));
   }
}

This error can be caused by an unclosed set of brackets.

int main {
  doSomething {}
  doSomething else {
}

Not so easy to spot, even in this 4 line example.

This error, in a 150 line main function, caused the bewildering error: "static declaration of ‘savePair’ follows non-static declaration". There was nothing wrong with my definition of function savePair, it was that unclosed bracket.

You may use formatters after picking value inside your datepicker directive. For example

angular.module('foo').directive('bar', function() {
    return {
        require: '?ngModel',
        link: function(scope, elem, attrs, ctrl) {
            if (!ctrl) return;

            ctrl.$formatters.push(function(value) {
                if (value) {
                    // format and return date here
                }

                return undefined;
            });
        }
    };
});

I solved this another way. Let's say you have your dependency.js

export const myFunction = () => { }

I create a depdency.mock.js file besides it with the following content:

export const mockFunction = jest.fn();

jest.mock('dependency.js', () => ({ myFunction: mockFunction }));

And in the test, before I import the file that has the dependency, I use:

import { mockFunction } from 'dependency.mock'
import functionThatCallsDep from './tested-code'

it('my test', () => {
    mockFunction.returnValue(false);

    functionThatCallsDep();

    expect(mockFunction).toHaveBeenCalled();

})

When you bind your Service to Activity with BIND_AUTO_CREATE your service is being killed just after your Activity is Destroyed and unbound. It does not depend on how you've implemented your Services unBind method it will be still killed.

The other way is to start your Service with startService method from your Activity. This way even if your Activity is destroyed your service won't be destroyed or even paused but you have to pause/destroy it by yourself with stopSelf/stopService when appropriate.

Why don't you guys use these NSDate compare methods:

- (NSDate *)earlierDate:(NSDate *)anotherDate;
- (NSDate *)laterDate:(NSDate *)anotherDate;

What's the first part of your Subversion repository URL?

• If your URL looks like: http://subversion/repos/, then you're probably going over Port 80.
• If your URL looks like: https://subversion/repos/, then you're probably going over Port 443.
• If your URL looks like: svn://subversion/, then you're probably going over Port 3690.
• If your URL looks like: svn+ssh://subversion/repos/, then you're probably going over Port 22.
• If your URL contains a port number like: http://subversion/repos:8080, then you're using that port.

I can't guarantee the first four since it's possible to reconfigure everything to use different ports, of if you go through a proxy of some sort.

If you're using a VPN, you may have to configure your VPN client to reroute these to their correct ports. A lot of places don't configure their correctly VPNs to do this type of proxying. It's either because they have some sort of anal-retentive IT person who's being overly security conscious, or because they simply don't know any better. Even worse, they'll give you a client where this stuff can't be reconfigured.

The only way around that is to log into a local machine over the VPN, and then do everything from that system.

f = open("file.txt")
lines = f.readlines()

Look over here. readlines() returns a list containing one line per element. Note that these lines contain the \n (newline-character) at the end of the line. You can strip off this newline-character by using the strip()-method. I.e. call lines[index].strip() in order to get the string without the newline character.

As joaquin noted, do not forget to f.close() the file.

Converting strint to integers is easy: int("12").

Try with this :

        android:endColor="#b5b6d2"
        android:startColor="#555994"
        android:type="linear" />

    <corners

I had this problem recently where apt install wget does not find anything. As it turns out apt update was never run.

apt update
apt install wget

After discussing this with a coworker we mused that apt update is likely not run in order to save both time and space in the docker image.

You can access the keys with ${!array[@]}:

bash-4.0$ echo "${!array[@]}"
foo bar

Then, iterating over the key/value pairs is easy:

for i in "${!array[@]}"
do
  echo "key :" $i
  echo "value:" ${array[$i]}
done

I also tried using pymysql (on my Win7 x64 machine, Python 3.3), without too much luck. I downloaded the .tar.gz, extract, ran "setup.py install", and everything seemed fine. Until I tried connecting to a database, and got "KeyError [56]". An error which I was unable to find documented anywhere.

So I gave up on pymysql, and I settled on the Oracle MySQL connector.

It comes as a setup package, and works out of the box. And it also seems decently documented.

This is an old question, and this is somewhat subtly mentioned in the other posts, but the explanation that made this click for me is that non fast forward merges will require a separate commit.

To my knowledge, Ejabberd (http://www.ejabberd.im/) is the parent, this is XMPP server which provide quite good features of open source, Whatsapp uses some modified version of this, facebook messaging also uses a modified version of this. Some more chat applications likes Samsung's ChatOn, Nimbuzz messenger all use ejabberd based ones and Erlang solutions also have modified version of this ejabberd which they claim to be highly scalable and well tested with more performance improvements and renamed as MongooseIM.

Ejabberd is the server which has most of the featured implemented when compared to other. Since it is build in Erlang it is highly scalable horizontally.

You could always change the opacity of the image, given the difficulty of any alternatives this might be the best approach.

CSS:

.tinted { opacity: 0.8; }

If you're interested in better browser compatability, I suggest reading this:

http://css-tricks.com/css-transparency-settings-for-all-broswers/

If you're determined enough you can get this working as far back as IE7 (who knew!)

Note: As JGonzalezD points out below, this only actually darkens the image if the background colour is generally darker than the image itself. Although this technique may still be useful if you don't specifically want to darken the image, but instead want to highlight it on hover/focus/other state for whatever reason.

I have read several articles discouraging inheritance in projects (as opposed to libraries/frameworks), and encouraging to program agaisnt interfaces, no against implementations.
They also advocate OO by composition: if you need the functions in class a and b, make c having members/fields of this type:

class C
{
    private $a, $b;

    public function __construct($x, $y)
    {
        $this->a = new A(42, $x);
        $this->b = new B($y);
    }

    protected function DoSomething()
    {
        $this->a->Act();
        $this->b->Do();
    }
}

I agree with Luke Vo's solution. I thought it would better to omit justify-content: space-between; from layout-wrapper and add margin-top: auto; to footer.

You wouldn't want your body to be hanging in the middle and only have footer pushed to the bottom.

This approach addresses any content extending beyond the viewport.

I faced this problem on MacOS High Sierra 10.13.5 after upgrading Xcode.

When I run git command, I received below message:

Agreeing to the Xcode/iOS license requires admin privileges, please run “sudo xcodebuild -license” and then retry this command.

After running sudo xcodebuild -license command, below message appears:

You have not agreed to the Xcode license agreements. You must agree to both license agreements below in order to use Xcode.

Hit the Enter key to view the license agreements at '/Applications/Xcode.app/Contents/Resources/English.lproj/License.rtf'

Typing Enter key to open license agreements and typing space key to review details of it, until below message appears:

By typing 'agree' you are agreeing to the terms of the software license agreements. Type 'print' to print them or anything else to cancel, [agree, print, cancel]

The final step is simply typing agree to sign with the license agreement.

After typing git command, we can check that VSCode detected git again.

nothing much to add,

1 - if you want to execute a query in a loop (more than 1 time), prepared statement can be faster, because of optimization that you mentioned.

2 - parameterized query is a good way to avoid SQL Injection. Parameterized querys are only available in PreparedStatement.

You can use transitions to delay the :hover effect you want, if the effect is CSS-based.

For example

div{
    transition: 0s background-color;
}

div:hover{
    background-color:red;    
    transition-delay:1s;
}

this will delay applying the the hover effects (background-color in this case) for one second.

Demo of delay on both hover on and off:

div{_x000D_
    display:inline-block;_x000D_
    padding:5px;_x000D_
    margin:10px;_x000D_
    border:1px solid #ccc;_x000D_
    transition: 0s background-color;_x000D_
    transition-delay:1s;_x000D_
}_x000D_
div:hover{_x000D_
    background-color:red;_x000D_
}

<div>delayed hover</div>

Demo of delay only on hover on:

div{_x000D_
    display:inline-block;_x000D_
    padding:5px;_x000D_
    margin:10px;_x000D_
    border:1px solid #ccc;_x000D_
    transition: 0s background-color;_x000D_
}_x000D_
div:hover{_x000D_
    background-color:red;    _x000D_
    transition-delay:1s;_x000D_
}

<div>delayed hover</div>

Vendor Specific Extentions for Transitions and W3C CSS3 transitions

Try this:

 DatePicker datePicker = (DatePicker) findViewById(R.id.datePicker1);
 int day = datePicker.getDayOfMonth();
 int month = datePicker.getMonth() + 1;
 int year = datePicker.getYear();

I just found out that regexp_substr() is perfect for this purpose :)

My challenge is picking the right-hand 16 chars from a reference string which theoretically can be everything from 7ish to 250ish chars long. It annoys me that substr( OurReference , -16 ) returns null when length( OurReference ) < 16. (On the other hand, it's kind of logical, too, that Oracle consequently returns null whenever a call to substr() goes beyond a string's boundaries.) However, I can set a regular expression to recognise everything between 1 and 16 of any char right before the end of the string:

regexp_substr( OurReference , '.{1,16}$' )

When it comes to performance issues regarding regular expressions, I can't say which of the GREATER() solution and this one performs best. Anyone test this? Generally I've experienced that regular expressions are quite fast if they're written neat and well (as this one).

Good luck! :)

First you define a thread. And if you never call join() or detach() before calling the thread destructor, the program will abort.

As follows, calling a thread destructor without first calling join (to wait for it to finish) or detach is guarenteed to immediately call std::terminate and end the program.

Either implicitly detaching or joining a joinable() thread in its destructor could result in difficult to debug correctness (for detach) or performance (for join) bugs encountered only when an exception is raised. Thus the programmer must ensure that the destructor is never executed while the thread is still joinable.

There is no difference between them, it just a file extension for image/jpeg mime type. In fact file extension for image/jpeg is .jpg, .jpeg, .jpe .jif, .jfif, .jfi

Simply use Path.GetFileName

Here - Extract folder name from the full path of a folder:

string folderName = Path.GetFileName(@"c:\projects\root\wsdlproj\devlop\beta2\text");//Return "text"

Here is some extra - Extract folder name from the full path of a file:

string folderName = Path.GetFileName(Path.GetDirectoryName(@"c:\projects\root\wsdlproj\devlop\beta2\text\GTA.exe"));//Return "text"

Here's my imperative version of mkdirp for nodejs.

function mkdirSyncP(location) {
    let normalizedPath = path.normalize(location);
    let parsedPathObj = path.parse(normalizedPath);
    let curDir = parsedPathObj.root;
    let folders = parsedPathObj.dir.split(path.sep);
    folders.push(parsedPathObj.base);
    for(let part of folders) {
        curDir = path.join(curDir, part);
        if (!fs.existsSync(curDir)) {
            fs.mkdirSync(curDir);
        }
    }
}

If you want to print the bytes as chars you can use the String constructor.

byte[] bytes = new byte[] { -1, -128, 1, 127 };
System.out.println(new String(bytes, 0));

Suppress the @JoinColumn(name="categoria") on the ID field of the Categoria class and I think it will work.

Instead of set mouse=a use set mouse=r in .vimrc

(I'm always wondering why std::map does not include a member function for us to do so.)

Because it can't do it any better than you can do it. If a method's implementation will be no superior to a free function's implementation then in general you should not write a method; you should write a free function.

It's also not immediately clear why it's useful anyway.

Try this:

public void paint (Graphics g) {    
    Rectangle r = new Rectangle(xPos,yPos,width,height);
    g.fillRect(r.getX(), r.getY(), r.getWidth(), r.getHeight());  
}

[edit]

// With explicit casting
public void paint (Graphics g) {    
        Rectangle r = new Rectangle(xPos, yPos, width, height);
        g.fillRect(
           (int)r.getX(),
           (int)r.getY(),
           (int)r.getWidth(),
           (int)r.getHeight()
        );  
    }

In my case I have solved this annoying warning by simply adding the <!DOCTYPE xml> after the <?xml ... > tag.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>

Here is an improvement on miku's original answer that addresses Dennis Williamson's concerns about the case where the variable is not set:

the_world_is_flat=true

if ${the_world_is_flat:-false} ; then
    echo "Be careful not to fall off!"
fi

And to test if the variable is false:

if ! ${the_world_is_flat:-false} ; then
    echo "Be careful not to fall off!"
fi

About other cases with a nasty content in the variable, this is a problem with any external input fed to a program.

Any external input must be validated before trusting it. But that validation has to be done just once, when that input is received.

It doesn't have to impact the performance of the program by doing it on every use of the variable like Dennis Williamson suggests.

Sessions would be good choice for you. Take a look at these two examples from PHP Manual:

Code of page1.php

<?php
// page1.php

session_start();

echo 'Welcome to page #1';

$_SESSION['favcolor'] = 'green';
$_SESSION['animal']   = 'cat';
$_SESSION['time']     = time();

// Works if session cookie was accepted
echo '<br /><a href="page2.php">page 2</a>';

// Or pass along the session id, if needed
echo '<br /><a href="page2.php?' . SID . '">page 2</a>';
?>

Code of page2.php

<?php
// page2.php

session_start();

echo 'Welcome to page #2<br />';

echo $_SESSION['favcolor']; // green
echo $_SESSION['animal'];   // cat
echo date('Y m d H:i:s', $_SESSION['time']);

// You may want to use SID here, like we did in page1.php
echo '<br /><a href="page1.php">page 1</a>';
?>

To clear up things - SID is PHP's predefined constant which contains session name and its id. Example SID value:

PHPSESSID=d78d0851898450eb6aa1e6b1d2a484f1

Because Python is dynamically typed, the types of the objects don't matter in many cases. It's a better idea to accept anything.

To demonstrate what I mean, this tree class will accept anything for its two branches:

class BinaryTree:
    def __init__(self, left, right):
        self.left, self.right = left, right

And it could be used like this:

branch1 = BinaryTree(1,2)
myitem = MyClass()
branch2 = BinaryTree(myitem, None)
tree = BinaryTree(branch1, branch2)

If you remove the href attribute the anchor will be not focusable and it will look like simple text, but it will still be clickable.

I was facing the same problem. For my solution, I added br enclosed between 2 brackets < > enclosed in double quotation marks, and preceded and followed by the + sign:

+"<br>"+

Try this in your browser and see, it certainly works in my Internet Explorer.

Meaning of @classmethod and @staticmethod?

• A method is a function in an object's namespace, accessible as an attribute.
• A regular (i.e. instance) method gets the instance (we usually call it self) as the implicit first argument.
• A class method gets the class (we usually call it cls) as the implicit first argument.
• A static method gets no implicit first argument (like a regular function).

when should I use them, why should I use them, and how should I use them?

You don't need either decorator. But on the principle that you should minimize the number of arguments to functions (see Clean Coder), they are useful for doing just that.

class Example(object):

    def regular_instance_method(self):
        """A function of an instance has access to every attribute of that 
        instance, including its class (and its attributes.)
        Not accepting at least one argument is a TypeError.
        Not understanding the semantics of that argument is a user error.
        """
        return some_function_f(self)

    @classmethod
    def a_class_method(cls):
        """A function of a class has access to every attribute of the class.
        Not accepting at least one argument is a TypeError.
        Not understanding the semantics of that argument is a user error.
        """
        return some_function_g(cls)

    @staticmethod
    def a_static_method():
        """A static method has no information about instances or classes
        unless explicitly given. It just lives in the class (and thus its 
        instances') namespace.
        """
        return some_function_h()

For both instance methods and class methods, not accepting at least one argument is a TypeError, but not understanding the semantics of that argument is a user error.

(Define some_function's, e.g.:

some_function_h = some_function_g = some_function_f = lambda x=None: x

and this will work.)

dotted lookups on instances and classes:

A dotted lookup on an instance is performed in this order - we look for:

1. a data descriptor in the class namespace (like a property)
2. data in the instance __dict__
3. a non-data descriptor in the class namespace (methods).

Note, a dotted lookup on an instance is invoked like this:

instance = Example()
instance.regular_instance_method 

and methods are callable attributes:

instance.regular_instance_method()

instance methods

The argument, self, is implicitly given via the dotted lookup.

You must access instance methods from instances of the class.

>>> instance = Example()
>>> instance.regular_instance_method()
<__main__.Example object at 0x00000000399524E0>

class methods

The argument, cls, is implicitly given via dotted lookup.

You can access this method via an instance or the class (or subclasses).

>>> instance.a_class_method()
<class '__main__.Example'>
>>> Example.a_class_method()
<class '__main__.Example'>

static methods

No arguments are implicitly given. This method works like any function defined (for example) on a modules' namespace, except it can be looked up

>>> print(instance.a_static_method())
None

Again, when should I use them, why should I use them?

Each of these are progressively more restrictive in the information they pass the method versus instance methods.

Use them when you don't need the information.

This makes your functions and methods easier to reason about and to unittest.

Which is easier to reason about?

def function(x, y, z): ...

or

def function(y, z): ...

or

def function(z): ...

The functions with fewer arguments are easier to reason about. They are also easier to unittest.

These are akin to instance, class, and static methods. Keeping in mind that when we have an instance, we also have its class, again, ask yourself, which is easier to reason about?:

def an_instance_method(self, arg, kwarg=None):
    cls = type(self)             # Also has the class of instance!
    ...

@classmethod
def a_class_method(cls, arg, kwarg=None):
    ...

@staticmethod
def a_static_method(arg, kwarg=None):
    ...

Builtin examples

Here are a couple of my favorite builtin examples:

The str.maketrans static method was a function in the string module, but it is much more convenient for it to be accessible from the str namespace.

>>> 'abc'.translate(str.maketrans({'a': 'b'}))
'bbc'

The dict.fromkeys class method returns a new dictionary instantiated from an iterable of keys:

>>> dict.fromkeys('abc')
{'a': None, 'c': None, 'b': None}

When subclassed, we see that it gets the class information as a class method, which is very useful:

>>> class MyDict(dict): pass
>>> type(MyDict.fromkeys('abc'))
<class '__main__.MyDict'> 

My advice - Conclusion

Use static methods when you don't need the class or instance arguments, but the function is related to the use of the object, and it is convenient for the function to be in the object's namespace.

Use class methods when you don't need instance information, but need the class information perhaps for its other class or static methods, or perhaps itself as a constructor. (You wouldn't hardcode the class so that subclasses could be used here.)

   self.tableView.tableHeaderView = segmentedControl; 

If you want it to obey your width and height properly though enclose your segmentedControl in a UIView first as the tableView likes to mangle your view a bit to fit the width.

You can simply use Query Builder rather than Eloquent, this code directly update your data in the database :) This is a sample:

DB::table('post')
            ->where('id', 3)
            ->update(['title' => "Updated Title"]);

You can check the documentation here for more information: http://laravel.com/docs/5.0/queries#updates

If you are using the Office 365 SMTP gateway then "SMTP Error: data not accepted." is the response you will get if the mailbox is full (even if you are just sending from it).

Try deleting some messages out of the mailbox.

Try new_list = a[0:2] + [a[4]] + a[6:].

Or more generally, something like this:

from itertools import chain
new_list = list(chain(a[0:2], [a[4]], a[6:]))

This works with other sequences as well, and is likely to be faster.

Or you could do this:

def chain_elements_or_slices(*elements_or_slices):
    new_list = []
    for i in elements_or_slices:
        if isinstance(i, list):
            new_list.extend(i)
        else:
            new_list.append(i)
    return new_list

new_list = chain_elements_or_slices(a[0:2], a[4], a[6:])

But beware, this would lead to problems if some of the elements in your list were themselves lists. To solve this, either use one of the previous solutions, or replace a[4] with a[4:5] (or more generally a[n] with a[n:n+1]).

Simply use \1 instead of $1:

In [1]: import re

In [2]: method = 'images/:id/huge'

In [3]: re.sub(r'(:[a-z]+)', r'<span>\1</span>', method)
Out[3]: 'images/<span>:id</span>/huge'

Also note the use of raw strings (r'...') for regular expressions. It is not mandatory but removes the need to escape backslashes, arguably making the code slightly more readable.

I just managed this problem, after several days of trying the above solutions. So I closed the emulator, run AVD manager and in device menu choose - "wipe data" So in next run I was free from stucked debugger.

No, you can't use sizeof(ptr) to find the size of array ptr is pointing to.

Though allocating extra memory(more than the size of array) will be helpful if you want to store the length in extra space.

Old question, but just for posterity.

I've found the easiest way to do it is to have the image as the background image of the navbar-brand. Just makes sure to put in a custom width.

.navbar-brand
{
    margin-left: auto;
    margin-right: auto;
    width: 150px;
    background-image: url('logo.png');
}

For anyone still googling this, go to \blackboard\config\tomcat\conf and in wrapper.conf put an extra line in wrapper.java.classpath pointing to the sqljdbc4.jar and then update the wrapper.conf.bb as well

Then restart the blackboard services and tomcat and it should work

It won't work by simply setting your java classpath, you have to set it up in the blackboard config files to point to your jar file with the jdbc library

FWIW I created a JavaScript class that can be used at run-time.
It's over on GitHub, here.

There is a readme there with a more in-depth explanation, but I'll do a quick example below:

var ba = new BootstrapAlert();
ba.addP("Some content here");
$("body").append(ba.render());

The above would create a simple primary alert with a paragraph element inside containing the text "Some content here".

There are also options that can be set on initialisation.
For your requirement you'd do:

var ba = new BootstrapAlert({
    dismissible: true,
    background: 'warning'
});
ba.addP("Invalid Credentials");
$("body").append(ba.render());

The render method will return an HTML element, which can then be inserted into the DOM. In this case, we append it to the bottom of the body tag.

This is a work in progress library, but it still is in a very good working order.

If the object is actually a Boolean instance, then just cast it:

boolean di = (Boolean) someObject;

The explicit cast will do the conversion to Boolean, and then there's the auto-unboxing to the primitive value. Or you can do that explicitly:

boolean di = ((Boolean) someObject).booleanValue();

If someObject doesn't refer to a Boolean value though, what do you want the code to do?

Personally, I use that:

    final Spinner spinner = (Spinner) (view.findViewById(R.id.userList));
    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {                

            userSelectedIndex = position;
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {
        }
    });  

You need to turn this into a string. You can do this using the stringify method in the JSON2 library.

http://www.json.org/

http://www.json.org/js.html

The code would look something like:

var myJSONText = JSON.stringify(myObject);

So

['Location Zero', 'Location One', 'Location Two'];

Will become:

"['Location Zero', 'Location One', 'Location Two']"

You'll have to refer to a PHP guru on how to handle this on the server. I think other answers here intimate a solution.

Data can be returned from the server in a similar way. I.e. you can turn it back into an object.

var myObject = JSON.parse(myJSONString);

Note for anyone running Vagrant: this can be caused by a bug with their shared folders. Specify NFS for your shared folders in your Vagrantfile to avoid this happening.

Simply adding type: "nfs" to the end will do the trick, like so:

config.vm.synced_folder ".", "/vagrant", type: "nfs"

you can just put keep_window_open (); before the return here is one example

int main()
{
    cout<<"hello world!\n";
    keep_window_open ();
    return 0;
}

I guess your code relates to Windows Forms.
You call BeginInvoke if you need something to be executed asynchronously in the UI thread: change control's properties in most of the cases.
Roughly speaking this is accomplished be passing the delegate to some procedure which is being periodically executed. (message loop processing and the stuff like that)

If BeginInvoke is called for Delegate type the delegate is just invoked asynchronously.
(Invoke for the sync version.)

If you want more universal code which works perfectly for WPF and WinForms you can consider Task Parallel Library and running the Task with the according context. (TaskScheduler.FromCurrentSynchronizationContext())

And to add a little to already said by others: Lambdas can be treated either as anonymous methods or expressions.
And that is why you cannot just use var with lambdas: compiler needs a hint.

UPDATE:

this requires .Net v4.0 and higher

// This line must be called in UI thread to get correct scheduler
var scheduler = System.Threading.Tasks.TaskScheduler.FromCurrentSynchronizationContext();

// this can be called anywhere
var task = new System.Threading.Tasks.Task( () => someformobj.listBox1.SelectedIndex = 0);

// also can be called anywhere. Task  will be scheduled for execution.
// And *IF I'm not mistaken* can be (or even will be executed synchronously)
// if this call is made from GUI thread. (to be checked) 
task.Start(scheduler);

If you started the task from other thread and need to wait for its completition task.Wait() will block calling thread till the end of the task.

Read more about tasks here.

Just a helpful hint, there is a company called Yodlee.com who provides this data. They do charge for the API. Companies like Mint.com use this API to gather bank and financial account data.

Also, checkout https://plaid.com/, they are a similar company Yodlee.com and provide both authentication API for several banks and REST-based transaction fetching endpoints.

This is my solution to fibonacci problem with recursion.

#include <iostream>
using namespace std;

int fibonacci(int n){
    if(n<=0)
        return 0;
    else if(n==1 || n==2)
        return 1;
    else
        return (fibonacci(n-1)+fibonacci(n-2));
}

int main() {
    cout << fibonacci(8);
    return 0;
}

Although it is not recommended, but if you really want to let your web application access a folder outside its deployment directory. You need to add following permission in java.policy file (path is as in the reply of Petey B)

permission java.io.FilePermission "your folder path", "write"

In your case it would be

permission java.io.FilePermission "S:/PDSPopulatingProgram/-", "write"

Here /- means any files or sub-folders inside this folder.

Warning: But by doing this, you are inviting some security risk.

for object "pega" that provides StartRunning(), StopRunning(), boolean getIsRunning() and integer getProgress100() returning value in range of 0 to 100, this provides text progress bar while running...

now = time.time()
timeout = now + 30.0
last_progress = -1

pega.StartRunning()

while now < timeout and pega.getIsRunning():
    time.sleep(0.5)
    now = time.time()

    progress = pega.getTubProgress100()
    if progress != last_progress:
        print('\r'+'='*progress+'-'*(100-progress)+' ' + str(progress) + "% ", end='', flush=True)
        last_progress = progress

pega.StopRunning()

progress = pega.getTubProgress100()
print('\r'+'='*progress+'-'*(100-progress)+' ' + str(progress) + "% ", flush=True)

following solution worked for me:

$("a[href^=#]").click(function(e)
        {
            e.preventDefault();
            var aid = $(this).attr('href');
            console.log(aid);
            aid = aid.replace("#", "");
            var aTag = $("a[name='"+ aid +"']");
            if(aTag == null || aTag.offset() == null)
                aTag = $("a[id='"+ aid +"']");

            $('html,body').animate({scrollTop: aTag.offset().top}, 1000);
        }
    );

Here is what worked for me.
I Have used rename command so that if any file contains spaces in name of it then , mv command dont get confused between spaces and actual file.

Here i replaced spaces , ' ' in a file name with '_' for all jpg files

#! /bin/bash
rename 'y/ /_/' *jpg         #replacing spaces with _
let x=0;
for i in *.jpg;do
    let x=(x+1)
    mv $i $x.jpg
done

Using Visual Studio

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

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

Using Process Explorer

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

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

Programmatically

Check this SO question that explains how to do it.

Easily! (because someone else already did the work for us...)

After spending a lot of time trying to this with the suggested answers I came across this codeplex project Windows Input Simulator which made it simple as can be to simulate a key press:

1. Install the package, can be done or from the NuGet package manager or from the package manager console like:

   Install-Package InputSimulator

2. Use this 2 lines of code:

   inputSimulator = new InputSimulator() inputSimulator.Keyboard.KeyDown(VirtualKeyCode.RETURN)

And that's it!

-------EDIT--------

The project page on codeplex is flagged for some reason, this is the link to the NuGet gallery.

there is much easier solution:

- (UIImage *)tranlucentWithAlpha:(CGFloat)alpha
{
    UIGraphicsBeginImageContextWithOptions(self.size, NO, self.scale);
    [self drawAtPoint:CGPointZero blendMode:kCGBlendModeNormal alpha:alpha];
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return image;
}

Try this server control which inherits directly from CheckBoxList (free, open source): http://dropdowncheckboxes.codeplex.com/

If you are looking for an specific hex character in the middle of the string, you can use "\xhh" where hh is the character in hexadecimal. I've tried and it works. I use framework for C++ Qt but it can solve problems in other cases, depends on the flavor you need to use (php, javascript, python , golang, etc.).

This answer was taken from:http://ult-tex.net/info/perl/

Another option is py-dom-xpath, it works seamlessly with minidom and is pure Python so works on appengine.

import xpath
xpath.find('//item', doc)

1. Make sure that you have Office runtime installed on the server.
2. If you are using Windows Server 2008 then using office interops is a lenghty configuration and here are the steps.

Better is to move to Open XML or you can configure as below

• Install MS Office Pro Latest (I used 2010 Pro)
• Create User ExcelUser. Assign WordUser with Admin Group
• Go to Computer -> Manage
• Add User with below options
• User Options Password Never Expires
• Password Cannot Be Change

Com+ Configuration

• Go to Control Panel - > Administrator -> Component Services -> DCOM Config
• Open Microsoft Word 97 - 2003 Properties
• General -> Authentication Level : None
• Security -> Customize all 3 permissions to allow everyone
• Identity -> This User -> Use ExcelUser /password
• Launch the Excel App to make sure everything is fine

3.Change the security settings of Microsoft Excel Application in DCOM Config.

Controlpanel --> Administrative tools-->Component Services -->computers --> myComputer -->DCOM Config --> Microsoft Excel Application.

Right click to get properties dialog. Go to Security tab and customize permissions

See the posts here: Error while creating Excel object , Excel manipulations in WCF using COM

I found this worked for me.

$username = 'user'
$password = 'password'

$securePassword = ConvertTo-SecureString $password -AsPlainText -Force
$credential = New-Object System.Management.Automation.PSCredential $username, $securePassword
Start-Process Notepad.exe -Credential $credential

Updated: changed to using single quotes to avoid special character issues noted by Paddy.

Here you go: http://mochajs.org/#test-level

it('accesses the network', function(done){
  this.timeout(500);
  [Put network code here, with done() in the callback]
})

For arrow function use as follows:

it('accesses the network', (done) => {
  [Put network code here, with done() in the callback]
}).timeout(500);

Tackling this task, I'd first find the number of decimal places in x, then round y accordingly. I'd use:

y.toFixed(x.toString().split(".")[1].length);

It should convert x to a string, split it over the decimal point, find the length of the right part, and then y.toFixed(length) should round y based on that length.

If you are using windows there is something different sort of situation

First open c:/apache24/conf/httpd.conf. The Apache folder is enough not specifically above path

After that you have to configure httpd.conf file.

Just after few lines there is pattern like:

#Listen _____________:80
Listen 80

Here You have to change for the localhost.

You have to enter ipv4 address for that you can open localhost.

Refer this video link and after that just bit more.

Change your environment variables:

In which you have to enter path:

c:apache24/bin

and
same in the SYSTEM variables

If any query feel free to ask.

Modern browsers support native querySelectorAll so you can do:

document.querySelectorAll('[data-foo="value"]');

https://developer.mozilla.org/en-US/docs/Web/API/Document.querySelectorAll

Details about browser compatibility:

• http://quirksmode.org/dom/core/#t14
• http://caniuse.com/queryselector

You can use jQuery to support obsolete browsers (IE9 and older):

$('[data-foo="value"]');

Go to httpd.conf on /Applications/MAMP/conf/apache and see if the LoadModule rewrite_module modules/mod_rewrite.so line is un-commented (without the # at the beginning)

and change these from ...

<VirtualHost *:80>
    ServerName ...
    DocumentRoot /....
</VirtualHost>

To this:

<VirtualHost *:80>
    ServerAdmin ...
    ServerName ...

    DocumentRoot ...
    <Directory ...>
        Options FollowSymLinks
        AllowOverride None
    </Directory>
    <Directory ...>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Order allow,deny
        allow from all
    </Directory>
</VirtualHost>

If you want to ignore namespaces completely, you can use this:

static void Main(string[] args)
{
    string xml =
        "<My_RootNode xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns=\"\">\n" +
        "    <id root=\"2.16.840.1.113883.3.51.1.1.1\" extension=\"someIdentifier\" xmlns=\"urn:hl7-org:v3\" />\n" +
        "    <creationTime xsi:nil=\"true\" xmlns=\"urn:hl7-org:v3\" />\n" +
        "</My_RootNode>";

    XmlDocument doc = new XmlDocument();
    doc.LoadXml(xml);

    XmlNode idNode = doc.SelectSingleNode("/*[local-name()='My_RootNode']/*[local-name()='id']");
}

The characters '<', and '>', are to indicate a place-holder, you should remove them to read:

php /usr/local/solusvm/scripts/pass.php --type=admin --comm=change --username=ADMINUSERNAME

I need to make a POST request via Curl from the command line. Data for this request is located in a file...

All you need to do is have the --data argument start with a @:

curl -H "Content-Type: text/xml" --data "@path_of_file" host:port/post-file-path

For example, if you have the data in a file called stuff.xml then you would do something like:

curl -H "Content-Type: text/xml" --data "@stuff.xml" host:port/post-file-path

The stuff.xml filename can be replaced with a relative or full path to the file: @../xml/stuff.xml, @/var/tmp/stuff.xml, ...

You can use MutationObserver to track attribute changes including data-* changes. For example:

var foo = document.getElementById('foo');_x000D_
_x000D_
var observer = new MutationObserver(function(mutations) {_x000D_
  console.log('data-select-content-val changed');_x000D_
});_x000D_
observer.observe(foo, { _x000D_
  attributes: true, _x000D_
  attributeFilter: ['data-select-content-val'] });_x000D_
_x000D_
foo.dataset.selectContentVal = 1;

 <div id='foo'></div>_x000D_

Your problem is here:

2013-11-14 17:57:20 5180 [ERROR] InnoDB: .\ibdata1 can't be opened in read-write mode

There's some problem with the ibdata1 file - maybe the permissions have changed on it? Perhaps some other process has it open. Does it even exist?

Fix this and possibly everything else will fall into place.

Just got this problem on a development machine (production works just fine). I modify my config in IIS to allow anonymous access and put my name and password as credential.

Not the best way I am sure but it works for testing purposes.

jQuery addClass API reference

My Answer might be coming late, but I think it can help newbie. You shall not see logs executed unless the changes are made as below.

2 Files have to be changes when you implement Log4net.

1. Add Reference of log4net.dll in the project.
2. app.config
3. Class file where you will implement Logs.

Inside [app.config] :

First, under 'configSections', you need to add below piece of code;

<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />

Then, under 'configuration' block, you need to write below piece of code.(This piece of code is customised as per my need , but it works like charm.)

<log4net debug="true">
    <logger name="log">
      <level value="All"></level>
      <appender-ref ref="RollingLogFileAppender" />
    </logger>

    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="log.txt" />
      <appendToFile value="true" />
      <rollingStyle value="Composite" />
      <maxSizeRollBackups value="1" />
      <maximumFileSize value="1MB" />
      <staticLogFileName value="true" />

      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date %C.%M [%line] %-5level - %message %newline %exception %newline" />
      </layout>
    </appender>
</log4net>

Inside Calling Class :

Inside the class where you are going to use this log4net, you need to declare below piece of code.

 ILog log = LogManager.GetLogger("log");

Now, you are ready call log wherever you want in that same class. Below is one of the method you can call while doing operations.

log.Error("message");

The meaning of final in java is: -applied to a variable means that the respective variable once initialized can no longer be modified

private final double numer = 12;

If you try to modify this value, you will get an error.

-applied to a method means that the respective method can't be override

 public final void displayMsg()
    {
        System.out.println("I'm in Base class - displayMsg()");
    }

But final method can be inherited because final keyword restricts the redefinition of the method.

-applied to a class means that the respective class can't be extended.

class Base
{

    public void displayMsg()
    {
        System.out.println("I'm in Base class - displayMsg()");
    }
}

The meaning of finally is :

class TestFinallyBlock{  
  public static void main(String args[]){  
  try{  
   int data=25/5;  
   System.out.println(data);  
  }  
  catch(NullPointerException e){System.out.println(e);}  
  finally{System.out.println("finally block is always executed");}  
  System.out.println("rest of the code...");  
  }  
} 

in this exemple even if the try-catch is executed or not, what is inside of finally will always be executed. The meaning of finalize:

class FinalizeExample{  
public void finalize(){System.out.println("finalize called");}  
public static void main(String[] args){  
FinalizeExample f1=new FinalizeExample();  
FinalizeExample f2=new FinalizeExample();  
f1=null;  
f2=null;  
System.gc();  
}}  

before calling the Garbage Collector.

I had black simulator screens only for iOS 11 sims. After trying to reset, reboot, reinstall and creating a brand new useraccount on my machine I found this solution:

defaults write com.apple.CoreSimulator.IndigoFramebufferServices FramebufferRendererHint 3

found in this answer here: Xcode 9 iOS Simulator becoming black screen after installing Xcode 10 beta

I had a nested directory structure i.e. I had multiple directories inside the main directory that contained the python modules.

I added the following script to my __init__.py file to import all the modules

import glob, re, os 

module_parent_directory = "path/to/the/directory/containing/__init__.py/file"

owd = os.getcwd()
if not owd.endswith(module_parent_directory): os.chdir(module_parent_directory)

module_paths = glob.glob("**/*.py", recursive = True)

for module_path in module_paths:
    if not re.match( ".*__init__.py$", module_path):
        import_path = module_path[:-3]
        import_path = import_path.replace("/", ".")
        exec(f"from .{import_path} import *")

os.chdir(owd)

Probably not the best way to achieve this, but I couldn't make anything else work for me.

Here's my solution using React Hooks. It combines the spread operator and the ternary operator.

style.js

export default {
  normal:{
    background: 'purple',
    color: '#ffffff'
  },
  hover: {
    background: 'red'
  }
}

Button.js

import React, {useState} from 'react';
import style from './style.js'

function Button(){

  const [hover, setHover] = useState(false);

  return(
    <button
      onMouseEnter={()=>{
        setHover(true);
      }}
      onMouseLeave={()=>{
        setHover(false);
      }}
      style={{
        ...style.normal,
        ...(hover ? style.hover : null)
      }}>

        MyButtonText

    </button>
  )
}

@jk1 answer is perfect, since @igor Ganapolsky asked, why can't we use Mockito.mock here? i post this answer.

For that we have provide one setter method for myobj and set the myobj value with mocked object.

class MyClass {
    MyInterface myObj;

    public void abc() {
        myObj.myMethodToBeVerified (new String("a"), new String("b"));
    }

    public void setMyObj(MyInterface obj)
    {
        this.myObj=obj;
    }
}

In our Test class, we have to write below code

class MyClassTest {

MyClass myClass = new MyClass();

    @Mock
    MyInterface myInterface;

    @test
    testAbc() {
        myclass.setMyObj(myInterface); //it is good to have in @before method
        myClass.abc();
        verify(myInterface).myMethodToBeVerified(new String("a"), new String("b"));
     }
}

I had to go another route for an assignment but this is what I ended up with.

my_array += ([x] * repeated_times)

There's a Windows answer, and a Debian answer, so here's a Mac one:

This assumes you're just here looking for a quick way to make a customisable alert sound, and not specifically the piezeoelectric beep you get on Windows:

os.system( "say beep" )

Disclaimer: You can replace os.system with a call to the subprocess module if you're worried about someone hacking on your beep code.

See: How to make the hardware beep sound in Mac OS X 10.6

For anyone else that may run into this issue, turns out that even if you include #!/usr/bin/env python3 at the beginning of your script, the shebang is ignored if the file isn't executable.

To determine whether or not your file is executable:

• run ./filename.py from the command line
• if you get -bash: ./filename.py: Permission denied, run chmod a+x filename.py
• run ./filename.py again

If you've included import sys; print(sys.version) as Kevin suggested, you'll now see that the script is being interpreted by python3

CSS provides only two values for its "list-style-position" - inside and outside. With "inside" second lines are flush with the list points not with the superior line:

In ordered lists, without intervention, if you give "list-style-position" the value "inside", the second line of a long list item will have no indent, but will go back to the left edge of the list (i.e. it will left-align with the number of the item). This is peculiar to ordered lists and doesn't happen in unordered lists.

If you instead give "list-style-position" the value "outside", the second line will have the same indent as the first line.

I had a list with a border and had this problem. With "list-style-position" set to "inside", my list didn't look like I wanted it to. But with "list-style-position" set to "outside", the numbers of the list items fell outside the box.

I solved this by simply setting a wider left margin for the whole list, which pushed the whole list toward the right, back into the position it was in before.

CSS:

ol.classname {margin:0;padding:0;}

ol.classname li {margin:0.5em 0 0 0;padding-left:0;list-style-position:outside;}

HTML:

<ol class="classname" style="margin:0 0 0 1.5em;">

Both isVisible() and isAdded() return true as soon as the Fragment is created, and not even actually visible. The only solution that actually works is:

if (isAdded() && isVisible() && getUserVisibleHint()) {
    // ... do your thing
}

This does the job. Period.

NOTICE: getUserVisibleHint() is now deprecated. be careful.

Css is going to work in same manner i assume.

You can center the content with something like this :

.center{
     text-align:center;
}

Update

To adjust the width in proper manner, modify your DOM as below :

<div class="item-input-inset">
    <label class="item-input-wrapper"> Date
        <input type="text" placeholder="Text Area" />
    </label>
</div>
<div class="item-input-inset">
    <label class="item-input-wrapper"> Suburb
        <input type="text" placeholder="Text Area" />
    </label>
</div>

CSS

label {
    display:inline-block;
    border:1px solid red;
    width:100%;
    font-weight:bold;
}

input{
    float:right; /* shift to right for alignment*/
    width:80% /* set a width, you can use max-width to limit this as well*/
}

Demo

final update

If you don't plan to modify existing HTML (one in your question originally), below css would make me your best friend!! :)

html, body, .con {
    height:100%;
    margin:0;
    padding:0;
}
.item-input-inset {
    display:inline-block;
    width:100%;
    font-weight:bold;
}
.item-input-inset > h4 {
    float:left;
    margin-top:0;/* important alignment */
    width:15%;
}
.item-input-wrapper {
    display:block;
    float:right;
    width:85%;
}
input {
    width:100%;
}

Demo

After executing the below regex, your answer is in the first capture.

/^(.*?)\.txt/

What does the DTD have to say?

If the XML file is for communicating with other existing software (e.g., SOAP), then check that software for what it expects.

If the XML file is for serialisation or communication with non-existing software (e.g., the one you're writing), you can define it. In which case, I'd suggest something that is both easy to parse in your language(s) of choice, and easy to read for humans. e.g., if your language (whether VB.NET or C#.NET or whatever) allows you to parse ISO dates (YYYY-MM-DD) easily, that's the one I'd suggest.

Go to your Django project home directory and do:

./manage.py --version

@Max: is right about the creation time.

However, if you want to calculate the elapsed days argument for one of the -atime, -ctime, -mtime parameters, you can use the following expression

ELAPSED_DAYS=$(( ( $(date +%s) - $(date -d '2008-09-24' +%s) ) / 60 / 60 / 24 - 1 ))

Replace "2008-09-24" with whatever date you want and ELAPSED_DAYS will be set to the number of days between then and today. (Update: subtract one from the result to align with find's date rounding.)

So, to find any file modified on September 24th, 2008, the command would be:

find . -type f -mtime $(( ( $(date +%s) - $(date -d '2008-09-24' +%s) ) / 60 / 60 / 24 - 1 ))

This will work if your version of find doesn't support the -newerXY predicates mentioned in @Arve:'s answer.

You can essentially do this 2 ways:

The .htaccess route with mod_rewrite

Add a file called .htaccess in your root folder, and add something like this:

RewriteEngine on
RewriteRule ^/?Some-text-goes-here/([0-9]+)$ /picture.php?id=$1

This will tell Apache to enable mod_rewrite for this folder, and if it gets asked a URL matching the regular expression it rewrites it internally to what you want, without the end user seeing it. Easy, but inflexible, so if you need more power:

The PHP route

Put the following in your .htaccess instead: (note the leading slash)

FallbackResource /index.php

This will tell it to run your index.php for all files it cannot normally find in your site. In there you can then for example:

$path = ltrim($_SERVER['REQUEST_URI'], '/');    // Trim leading slash(es)
$elements = explode('/', $path);                // Split path on slashes
if(empty($elements[0])) {                       // No path elements means home
    ShowHomepage();
} else switch(array_shift($elements))             // Pop off first item and switch
{
    case 'Some-text-goes-here':
        ShowPicture($elements); // passes rest of parameters to internal function
        break;
    case 'more':
        ...
    default:
        header('HTTP/1.1 404 Not Found');
        Show404Error();
}

This is how big sites and CMS-systems do it, because it allows far more flexibility in parsing URLs, config and database dependent URLs etc. For sporadic usage the hardcoded rewrite rules in .htaccess will do fine though.

A .zip file is required in order to include npm modules in Lambda. And you really shouldn't be using the Lambda web editor for much of anything- as with any production code, you should be developing locally, committing to git, etc.

MY FLOW:

1) My Lambda functions are usually helper utilities for a larger project, so I create a /aws/lambdas directory within that to house them.

2) Each individual lambda directory contains an index.js file containing the function code, a package.json file defining dependencies, and a /node_modules subdirectory. (The package.json file is not used by Lambda, it's just so we can locally run the npm install command.)

package.json:

{
  "name": "my_lambda",
  "dependencies": {
    "svg2png": "^4.1.1"
  }
}

3) I .gitignore all node_modules directories and .zip files so that the files generated from npm installs and zipping won't clutter our repo.

.gitignore:

# Ignore node_modules
**/node_modules

# Ignore any zip files
*.zip

4) I run npm install from within the directory to install modules, and develop/test the function locally.

5) I .zip the lambda directory and upload it via the console.

(IMPORTANT: Do not use Mac's 'compress' utility from Finder to zip the file! You must run zip from the CLI from within the root of the directory- see here)

zip -r ../yourfilename.zip * 

NOTE:

You might run into problems if you install the node modules locally on your Mac, as some platform-specific modules may fail when deployed to Lambda's Linux-based environment. (See https://stackoverflow.com/a/29994851/165673)

The solution is to compile the modules on an EC2 instance launched from the AMI that corresponds with the Lambda Node.js runtime you're using (See this list of Lambda runtimes and their respective AMIs).

For Winforms

private void listBox1_DoubleClick(object sender, MouseEventArgs e)
    {
        int index = this.listBox1.IndexFromPoint(e.Location);
        if (index != System.Windows.Forms.ListBox.NoMatches)
        {
            MessageBox.Show(listBox1.SelectedItem.ToString());
        }
    }

and

public Form()
{
    InitializeComponent();
    listBox1.MouseDoubleClick += new MouseEventHandler(listBox1_DoubleClick);
}

that should also, prevent for the event firing if you select an item then click on a blank area.

A turkish one. If someone is still interested.

 $('input[type="text"]').keyup(function() {
    $(this).val($(this).val().replace(/^([a-zA-Z\s\ö\ç\s\i\i\g\ü\Ö\Ç\S\I\G\Ü])|\s+([a-zA-Z\s\ö\ç\s\i\i\g\ü\Ö\Ç\S\I\G\Ü])/g, function ($1) {
        if ($1 == "i")
            return "I";
        else if ($1 == " i")
            return " I";
        return $1.toUpperCase();
    }));
});

Would all these dates be in the database already or do you just want to know the days between the two dates? If it's the first you could use the BETWEEN or <= >= to find the dates between

EXAMPLE:

SELECT column_name(s)
FROM table_name
WHERE column_name
BETWEEN value1 AND value2

OR

SELECT column_name(s)
FROM table_name
WHERE column_name
value1 >= column_name
AND column_name =< value2

You'll need a datasource for working with JdbcTemplate.

JdbcTemplate template = new JdbcTemplate(yourDataSource);

template.update(
    new PreparedStatementCreator() {
        public PreparedStatement createPreparedStatement(Connection connection)
            throws SQLException {

            PreparedStatement statement = connection.prepareStatement(ourInsertQuery);
            //statement.setLong(1, beginning); set parameters you need in your insert

            return statement;
        }
    });

You are mixing the deprecated mysql extension with mysqli.

Try something like:

$sql = mysqli_query($success, "SELECT * FROM login WHERE username = '".$_POST['username']."' and password = '".md5($_POST['password'])."'");
$row = mysqli_num_rows($sql);

        $services = $this->Service->find('all', array(
            'limit' =>4,
            'fields' => array('Service.*','ServiceImage.*'),
            'joins' => array(
                array(
                        'table' => 'services_images',
                        'alias' => 'ServiceImage',
                        'type' => 'INNER',
                        'conditions' => array(
                        'ServiceImage.service_id' =>'Service.id'
                        )
                    ),
                ),
            )
        );

It goges to array is null.

Be careful if you have to deal with large numbers.

int[] arr = new int[]{Integer.MIN_VALUE, Integer.MIN_VALUE};
long sum = Arrays.stream(arr).sum(); // Wrong: sum == 0

The sum above is not 2 * Integer.MIN_VALUE. You need to do this in this case.

long sum = Arrays.stream(arr).mapToLong(Long::valueOf).sum(); // Correct
