I followed below steps to install mcrypt for PHP7.2 using PECL.

1. Install PECL

apt-get install php-pecl

2. Before installing MCRYPT you must install libmcrypt

apt-get install libmcrypt-dev libreadline-dev

3. Install MCRYPT 1.0.1 using PECL

pecl install mcrypt-1.0.1

4. After the successful installation

You should add "extension=mcrypt.so" to php.ini

Please comment below if you need any assistance. :-)

IMPORTANT !

According to php.net reference many (all) mcrypt functions have been DEPRECATED as of PHP 7.1.0. Relying on this function is highly discouraged.

If you are using mac, try giving root access to gradlew by doing

chmod +x ./gradlew

As of TypeScript 1.6, properties in object literals that do not have a corresponding property in the type they're being assigned to are flagged as errors.

Usually this error means you have a bug (typically a typo) in your code, or in the definition file. The right fix in this case would be to fix the typo. In the question, the property callbackOnLoactionHash is incorrect and should have been callbackOnLocationHash (note the mis-spelling of "Location").

This change also required some updates in definition files, so you should get the latest version of the .d.ts for any libraries you're using.

Example:

interface TextOptions {
    alignment?: string;
    color?: string;
    padding?: number;
}
function drawText(opts: TextOptions) { ... }
drawText({ align: 'center' }); // Error, no property 'align' in 'TextOptions'

But I meant to do that

There are a few cases where you may have intended to have extra properties in your object. Depending on what you're doing, there are several appropriate fixes

Type-checking only some properties

Sometimes you want to make sure a few things are present and of the correct type, but intend to have extra properties for whatever reason. Type assertions (<T>v or v as T) do not check for extra properties, so you can use them in place of a type annotation:

interface Options {
    x?: string;
    y?: number;
}

// Error, no property 'z' in 'Options'
let q1: Options = { x: 'foo', y: 32, z: 100 };
// OK
let q2 = { x: 'foo', y: 32, z: 100 } as Options;
// Still an error (good):
let q3 = { x: 100, y: 32, z: 100 } as Options;

These properties and maybe more

Some APIs take an object and dynamically iterate over its keys, but have 'special' keys that need to be of a certain type. Adding a string indexer to the type will disable extra property checking

Before

interface Model {
  name: string;
}
function createModel(x: Model) { ... }

// Error
createModel({name: 'hello', length: 100});

After

interface Model {
  name: string;
  [others: string]: any;
}
function createModel(x: Model) { ... }

// OK
createModel({name: 'hello', length: 100});

This is a dog or a cat or a horse, not sure yet

interface Animal { move; }
interface Dog extends Animal { woof; }
interface Cat extends Animal { meow; }
interface Horse extends Animal { neigh; }

let x: Animal;
if(...) {
  x = { move: 'doggy paddle', woof: 'bark' };
} else if(...) {
  x = { move: 'catwalk', meow: 'mrar' };
} else {
  x = { move: 'gallop', neigh: 'wilbur' };
}

Two good solutions come to mind here

Specify a closed set for x

// Removes all errors
let x: Dog|Cat|Horse;

or Type assert each thing

// For each initialization
  x = { move: 'doggy paddle', woof: 'bark' } as Dog;

This type is sometimes open and sometimes not

A clean solution to the "data model" problem using intersection types:

interface DataModelOptions {
  name?: string;
  id?: number;
}
interface UserProperties {
  [key: string]: any;
}
function createDataModel(model: DataModelOptions & UserProperties) {
 /* ... */
}
// findDataModel can only look up by name or id
function findDataModel(model: DataModelOptions) {
 /* ... */
}
// OK
createDataModel({name: 'my model', favoriteAnimal: 'cat' });
// Error, 'ID' is not correct (should be 'id')
findDataModel({ ID: 32 });

Ran into issues like, while running sudo apt-get install python3-env on Ubuntu WSL:

Err:1 http://security.ubuntu.com/ubuntu xenial-security/universe amd64 python3.5-venv amd64 3.5.2-2ubuntu0~16.04.9 
404  Not Found [IP: 2001:67c:1360:8001::23 80]

Running

sudo apt-get update

fixed those issues.

Whatever approach you take, make sure in the end that you have an updated version of curl and libcurl. You can do curl --version and see the versions.

Here's what I did to get the latest curl version installed in Ubuntu:

1. sudo add-apt-repository "deb http://mirrors.kernel.org/ubuntu wily main"
2. sudo apt-get update
3. sudo apt-get install curl

If you don't care about the security of your SSH keys, there are many good answers here. If you do, the best answer I found was from a link in a comment above to this GitHub comment by diegocsandrim. So that others are more likely to see it, and just in case that repo ever goes away, here is an edited version of that answer:

Most solutions here end up leaving the private key in the image. This is bad, as anyone with access to the image has access to your private key. Since we don't know enough about the behavior of squash, this may still be the case even if you delete the key and squash that layer.

We generate a pre-sign URL to access the key with aws s3 cli, and limit the access for about 5 minutes, we save this pre-sign URL into a file in repo directory, then in dockerfile we add it to the image.

In dockerfile we have a RUN command that do all these steps: use the pre-sing URL to get the ssh key, run npm install, and remove the ssh key.

By doing this in one single command the ssh key would not be stored in any layer, but the pre-sign URL will be stored, and this is not a problem because the URL will not be valid after 5 minutes.

The build script looks like:

# build.sh
aws s3 presign s3://my_bucket/my_key --expires-in 300 > ./pre_sign_url
docker build -t my-service .

Dockerfile looks like this:

FROM node

COPY . .

RUN eval "$(ssh-agent -s)" && \
    wget -i ./pre_sign_url -q -O - > ./my_key && \
    chmod 700 ./my_key && \
    ssh-add ./my_key && \
    ssh -o StrictHostKeyChecking=no [email protected] || true && \
    npm install --production && \
    rm ./my_key && \
    rm -rf ~/.ssh/*

ENTRYPOINT ["npm", "run"]

CMD ["start"]

My guess is that the directory ~/bin/sbt/bin is not in your PATH.

To execute programs or scripts that are in the current directory you need to prefix the command with ./, as in:

./sbt

This is a security feature in linux, so to prevent overriding of system commands (and other programs) by a malicious party dropping a file in your home directory (for example). Imagine a script called 'ls' that emails your /etc/passwd file to 3rd party before executing the ls command... Or one that executes 'rm -rf .'...

That said, unless you need something specific from the latest source code, you're best off doing what paradigmatic said in his post, and install it from the Typesafe repository.

If you have a text as

var sampleText ="ä_öü_ßÄ_ TESTED Ö_Ü!@#$%^&())(&&++===.XYZ"

To replace all special character (!@#$%^&())(&&++= ==.) without replacing the characters(including umlaut)

Use below regex

sampleText = sampleText.replace(/[`~!@#$%^&*()|+-=?;:'",.<>{}[]\/\s]/gi,'');

OUTPUT : sampleText = "ä_öü_ßÄ____TESTED_Ö_Ü_____________________XYZ"

This would replace all with an underscore which is provided as second argument to the replace function.You can add whatever you want as per your requirement

ExpandoObject is what are you looking for.

dynamic MyDynamic = new ExpandoObject(); // note, the type MUST be dynamic to use dynamic invoking.
MyDynamic.A = "A";
MyDynamic.B = "B";
MyDynamic.C = "C";
MyDynamic.TheAnswerToLifeTheUniverseAndEverything = 42;

Based on the previous answers, here is a simple alternative way of printing the R-version, followed by the name and version of each package loaded in the namespace. It works in the Jupyter notebook, where I had troubles running sessionInfo() and R --version.

print(paste("R", getRversion()))
print("-------------")
for (package_name in sort(loadedNamespaces())) {
    print(paste(package_name, packageVersion(package_name)))
}

Out:

[1] "R 3.2.2"
[1] "-------------"
[1] "AnnotationDbi 1.32.2"
[1] "Biobase 2.30.0"
[1] "BiocGenerics 0.16.1"
[1] "BiocParallel 1.4.3"
[1] "DBI 0.3.1"
[1] "DESeq2 1.10.0"
[1] "Formula 1.2.1"
[1] "GenomeInfoDb 1.6.1"
[1] "GenomicRanges 1.22.3"
[1] "Hmisc 3.17.0"
[1] "IRanges 2.4.6"
[1] "IRdisplay 0.3"
[1] "IRkernel 0.5"

The command line tools are not included with the latest version of Grunt (0.4 at time of writing) instead you need to install them separately.

This is a good idea because it means you can have different versions of Grunt running on different projects but still use the nice concise grunt command to run them.

So first install the grunt cli tools globally:

npm install -g grunt-cli

(or possibly sudo npm install -g grunt-cli ).

You can establish that's working by typing grunt --version

Now you can install the current version of Grunt local to your project. So from your project's location...

npm install grunt --save-dev

The save-dev switch isn't strictly necessary but is a good idea because it will mark grunt in its package.json devDependencies section as a development only module.

I had already installed the command line tools in xcode but I mine still errored out on:

line 3619: /usr/bin/gcc-4.2: No such file or directory

When I entered which gcc it returned

/usr/bin/gcc

When I entered gcc -v I got a bunch of stuff then

..  
gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

So I created a symlink:

cd /usr/bin
sudo ln -s gcc gcc-4.2

And it worked!

(the config.log file is located in the directory that make is trying to build something in)

For a very specific reason Type Nullable<int> put your cursor on Nullable and hit F12 - The Metadata provides the reason (Note the struct constraint):

public struct Nullable<T> where T : struct
{
...
}

There's no good reason for 1 to be true and 0 to be false; that's just the way things have always been notated. So from a logical perspective, the function in your API isn't "wrong", per se.

That said, it's normally not advisable to work against the idioms of whatever language or framework you're using without a damn good reason to do so, so whoever wrote this function was probably pretty bone-headed, assuming it's not simply a bug.

Authoring a homegrown sed replacement in pure Python with no external commands or additional dependencies is a noble task laden with noble landmines. Who would have thought?

Nonetheless, it is feasible. It's also desirable. We've all been there, people: "I need to munge some plaintext files, but I only have Python, two plastic shoelaces, and a moldy can of bunker-grade Maraschino cherries. Help."

In this answer, we offer a best-of-breed solution cobbling together the awesomeness of prior answers without all of that unpleasant not-awesomeness. As plundra notes, David Miller's otherwise top-notch answer writes the desired file non-atomically and hence invites race conditions (e.g., from other threads and/or processes attempting to concurrently read that file). That's bad. Plundra's otherwise excellent answer solves that issue while introducing yet more – including numerous fatal encoding errors, a critical security vulnerability (failing to preserve the permissions and other metadata of the original file), and premature optimization replacing regular expressions with low-level character indexing. That's also bad.

Awesomeness, unite!

import re, shutil, tempfile

def sed_inplace(filename, pattern, repl):
    '''
    Perform the pure-Python equivalent of in-place `sed` substitution: e.g.,
    `sed -i -e 's/'${pattern}'/'${repl}' "${filename}"`.
    '''

    pattern_compiled = re.compile(pattern)

    # For portability, NamedTemporaryFile() defaults to mode "w+b" (i.e., binary

The correct method is to register your custom URL Protocol in windows registry as follows:

[HKEY_CLASSES_ROOT\customurl]
@="Description here"
"URL Protocol"=""

[HKEY_CLASSES_ROOT\customurl\shell]

[HKEY_CLASSES_ROOT\customurl\shell\open]

[HKEY_CLASSES_ROOT\customurl\shell\open\command]
@="\"C:\\Path To Your EXE\\ExeName.exe\" \"%1\""

Once the above keys and values are added, from the web page, just call "customurl:\\parameter1=xxx&parameter2=xxx" . You will receive the entire url as the argument in exe, which you need to process inside your exe. Change 'customurl' with the text of your choice.

Personally i think you should learn the hard way first. It will make you a better programmer and you will be able to solve that one of a kind issue when it comes up. After you can do it with pure JavaScript then using jQuery to speed up development is just an added bonus.

If you can do it the hard way then you can do it the easy way, it doesn't work the other way around. That applies to any programming paradigm.

As stated on Installing MySQL-python on mac :

pip uninstall MySQL-python
brew install mysql
pip install MySQL-python

Then test it :

python -c "import MySQLdb"

I would do it using a for loop as shown below :

def determine_period(universe_array):
    tmp = universe_array
    for period in xrange(1, 13):
        tmp = apply_rules(tmp)
        if numpy.array_equal(tmp, universe_array):
            return period
    return 0

Think about this from an aspect-oriented point of view; what you want to do, really, is know all the classes at runtime that HAVE extended the Animal class. (I think that's a slightly more accurate description of your problem than your title; otherwise, I don't think you have a runtime question.)

So what I think you want is to create a constructor of your base class (Animal) which adds to your static array (I prefer ArrayLists, myself, but to each their own) the type of the current Class which is being instantiated.

So, roughly;

public abstract class Animal
    {
    private static ArrayList<Class> instantiatedDerivedTypes;
    public Animal() {
        Class derivedClass = this.getClass();
        if (!instantiatedDerivedClass.contains(derivedClass)) {
            instantiatedDerivedClass.Add(derivedClass);
        }
    }

Of course, you'll need a static constructor on Animal to initialize instantiatedDerivedClass... I think this'll do what you probably want. Note that this is execution-path dependent; if you have a Dog class that derives from Animal that never gets invoked, you won't have it in your Animal Class list.

An old question but still relevant today....due to so many developers in the enterprise space still using it.

My work involves designing and developing IoT (Internet of Things) solutions. Which includes developing code for small embedded devices that communicate with the Cloud.

It is clear REST is now widely accepted and useful, and pretty much the defacto standard for the web, even Microsoft has REST support included throughout Azure. If I needed to rely on SOAP I could not do what I need to do, as is just too big, bulky and annoying for small embedded devices.

REST is simple and clean and small. Making it ideal for small embedded devices. I always scream when I am working with a web developer who sends me a WSDLs. As I will have to begin an education campaign about why this just isn't going to work and why they are going to have to learn REST.

asyncio.wait is more low level than asyncio.gather.

As the name suggests, asyncio.gather mainly focuses on gathering the results. It waits on a bunch of futures and returns their results in a given order.

asyncio.wait just waits on the futures. And instead of giving you the results directly, it gives done and pending tasks. You have to manually collect the values.

Moreover, you could specify to wait for all futures to finish or just the first one with wait.

If you are in that phase of development where you have an method inside your context class that creates testdata for you, don't call it in your constructor, it will try to create those test records while you don't have tables yet. Just sharing my mistake...

//if passed exMins=0 it will delete as soon as it creates it.

function setCookie(cname, cvalue, exMins) {
    var d = new Date();
    d.setTime(d.getTime() + (exMins*60*1000));
    var expires = "expires="+d.toUTCString();  
    document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";
}

setCookie('cookieNameToDelete','',0) // this will delete the cookie.

Creating a dictionary as it has mentioned, but in this case each key has the name of the object name that you want to create. Then the value is set as the class you want to instantiate, see for example:

class MyClass:
   def __init__(self, name):
       self.name = name
       self.checkme = 'awesome {}'.format(self.name)
...

instanceNames = ['red', 'green', 'blue']

# Here you use the dictionary
holder = {name: MyClass(name=name) for name in instanceNames}

Then you just call the holder key and you will have all the properties and methods of your class available for you.

holder['red'].checkme

output:

'awesome red'

XAMPP Apache + MariaDB + PHP + Perl (X -any OS)

• After successful installation execute xampp-control.exe in XAMPP folder

• Start Apache and MySQL

• Open browser and in url type localhost or 127.0.0.1

• then you are welcomed with dashboard

By default your port is listing with 80.If you want you can change it to your desired port number in httpd.conf file.(If port 80 is already using with other app then you have to change it).

For example you changed port number 80 to 8090 then you can run as 'localhost:8090' or '127.0.0.1:8090'

An object technically is a dictionary.

var myMappings = {
    mykey1: 'myValue',
    mykey2: 'myValue'
};

var myVal = myMappings['myKey1'];

alert(myVal); // myValue

You can even loop through one.

for(var key in myMappings) {
    var myVal = myMappings[key];
    alert(myVal);
}

There is no reason whatsoever to reinvent the wheel. And of course, assignment goes like:

myMappings['mykey3'] = 'my value';

And ContainsKey:

if (myMappings.hasOwnProperty('myKey3')) {
    alert('key already exists!');
}

I suggest you follow this: http://javascriptissexy.com/how-to-learn-javascript-properly/

For JavaFX

import javafx.scene.paint.Color;

.

Color whiteColor = Color.valueOf("#ffffff");

We had a similar issue. We were trying to GET from:

[RoutePrefix("api/car")]
public class CarController: ApiController{

    [HTTPGet]
    [Route("")]
    public virtual async Task<ActionResult> GetAll(){

    }

}

So we would .GET("/api/car") and this would throw a 405 error.

The CarController.cs file was in the directory /api/car so when we were requesting this api endpoint, IIS would send back an error because it looked like we were trying to access a virtual directory that we were not allowed to.

Option 1: change / rename the directory the controller is in
Option 2: change the route prefix to something that doesn't match the virtual directory.

PCDATA – parsed character data. It parses all the data in an XML document.

Example:

<family>
    <mother>mom</mother>
    <father>dad</father>
</family>

Here, the <family> element contains 2 more elements: <mother> and <father>. So it parses further to get the text of mother and father to give the text value of family as “mom dad”

CDATA – unparsed character Data. This is the data that should not be parsed further in an xml document.

<family>
    <![CDATA[ 
       <mother>mom</mother>
       <father>dad</father>
    ]]>
</family>

Here, the text value of family will be <mother>mom</mother><father>dad</father>.

To return a file or filepath

URL resource = YourClass.class.getResource("abc");
File file = Paths.get(resource.toURI()).toFile(); // return a file
String filepath = Paths.get(resource.toURI()).toFile().getAbsolutePath();  // return file path

I've run into this as well, solution is usually to be sure to run the program as an administrator (right click, run as administrator.)

Try Making the Child Form's StartPosition Property set to Center Parent. This you can select from the form Properties.

Out of the box, the == operator only works for primitives. To get your code to work, you need to overload the == operator for your struct.

Note: Calling a lifecycle method from another one is not a good practice. In below example I tried to achieve that your onNewIntent will be always called irrespective of your Activity type.

OnNewIntent() always get called for singleTop/Task activities except for the first time when activity is created. At that time onCreate is called providing to solution for few queries asked on this thread.

You can invoke onNewIntent always by putting it into onCreate method like

@Override
public void onCreate(Bundle savedState){
    super.onCreate(savedState);
    onNewIntent(getIntent());
}

@Override
protected void onNewIntent(Intent intent) {
  super.onNewIntent(intent);
  //code
}

For Django version 1.7, if above solutions dont work then try the following

in settings.py add

#For email
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'

EMAIL_USE_TLS = True

EMAIL_HOST = 'smtp.gmail.com'

EMAIL_HOST_USER = '[email protected]'

#Must generate specific password for your app in [gmail settings][1]
EMAIL_HOST_PASSWORD = 'app_specific_password'

EMAIL_PORT = 587

#This did the trick
DEFAULT_FROM_EMAIL = EMAIL_HOST_USER

The last line did the trick for django 1.7

I had something like this, my suggestion would be to use java for things like this, don't put in boilerplate code

You try to access private member of one class from another. The fact that bar-class is declared within foo-class means that bar in visible only inside foo class, but that is still other class.

And what is p->param?

Actually, it isn't clear what do you want to do

I figured out what it was! When I cleared the fields using the each() method, it also cleared the hidden field which the php needed to run:

if ($_POST['action'] == 'addRunner') 

I used the :not() on the selection to stop it from clearing the hidden field.

I usually sort the data by the field I need to do the distinct count of then use IF(A2=A1,0,1); you get then get a 1 in the top row of each group of IDs. Simple and doesn't take any time to calculate on large datasets.

I would recommend a Set implementation where the use case is limit to referencing or search for existence and Tuple implementation where the use case requires you to perform iteration. A list is a low-level implementation and requires significant memory overhead.

The issue is you're creating a List using Arrays.asList() method with fixed Length meaning that

Since the returned List is a fixed-size List, we can’t add/remove elements.

See the below block of code that I am using

This iteration will give an Exception Since it is an iteration list Created by asList() so remove and add are not possible, it is a fixed array

List<String> words = Arrays.asList("pen", "pencil", "sky", "blue", "sky", "dog"); 
for (String word : words) {
    if ("sky".equals(word)) {
        words.remove(word);
    }
}   

This will work fine since we are taking a new ArrayList we can perform modifications while iterating

List<String> words1 = new ArrayList<String>(Arrays.asList("pen", "pencil", "sky", "blue", "sky", "dog"));
for (String word : words) {
    if ("sky".equals(word)) {
        words.remove(word);
    }
}

You can use the ScriptManager.RegisterStartupScript(); to call any of your javascript event/Client Event from the server. For example, to display a message using javascript's alert();, you can do this:

protected void ddl_SelectedIndexChanged(object sender, EventArgs e)
{
Response.write("<script>alert('This is my message');</script>");
 //----or alternatively and to be more proper
 ScriptManager.RegisterStartupScript(this, this.GetType(), "callJSFunction", "alert('This is my message')", true);
}

To be exact for you, do this...

protected void ddl_SelectedIndexChanged(object sender, EventArgs e)
{
 ScriptManager.RegisterStartupScript(this, this.GetType(), "callJSFunction", "CalcTotalAmt();", true);
}

This is best done in the MenuItemDataBound.

protected void NavigationMenu_MenuItemDataBound(object sender, MenuEventArgs e)
{
    if (!Page.User.IsInRole("Admin"))
    {
        if (e.Item.NavigateUrl.Equals("/admin"))
        {
            if (e.Item.Parent != null)
            {
                MenuItem menu = e.Item.Parent;

                menu.ChildItems.Remove(e.Item);
            }
            else
            {
                Menu menu = (Menu)sender;

                menu.Items.Remove(e.Item);
            }               
        }
    }
}

Because the example used the NavigateUrl it is not language specific and works on sites with localized site maps.

Often, you will want a fast install from local archives, without probing PyPI.

First, download the archives that fulfill your requirements:

$ pip install --download <DIR> -r requirements.txt

Then, install using –find-links and –no-index:

$ pip install --no-index --find-links=[file://]<DIR> -r requirements.txt

You could try the "Microsoft Date and Time Picker Control". To use it, in the Toolbox, you right-click and choose "Additional Controls...". Then you check "Microsoft Date and Time Picker Control 6.0" and OK. You will have a new control in the Toolbox to do what you need.

I just found some printscreen of this on : http://www.logicwurks.com/CodeExamplePages/EDatePickerControl.html Forget the procedures, just check the printscreens.

In conclusion, when you use a local variable of a type that implements IDisposable, always, without exception, use using¹.

If you use nonlocal IDisposable variables, then always implement the IDisposable pattern.

Two simple rules, no exception¹. Preventing resource leaks otherwise is a real pain in the *ss.

¹⁾: The only exception is – when you're handling exceptions. It might then be less code to call Dispose explicitly in the finally block.

You can try this:

function Get-UrlStatusCode([string] $Url)
{
    try
    {
        (Invoke-WebRequest -Uri $Url -UseBasicParsing -DisableKeepAlive).StatusCode
    }
    catch [Net.WebException]
    {
        [int]$_.Exception.Response.StatusCode
    }
}

I had the same problem when I wrote two upstreams in NGINX conf

upstream php_upstream {
    server unix:/var/run/php/my.site.sock;
    server 127.0.0.1:9000;
}

...

fastcgi_pass php_upstream;

but in /etc/php/7.3/fpm/pool.d/www.conf I listened the socket only

listen = /var/run/php/my.site.sock

So I need just socket, no any 127.0.0.1:9000, and I just removed IP+port upstream

upstream php_upstream {
    server unix:/var/run/php/my.site.sock;
}

This could be rewritten without an upstream

fastcgi_pass unix:/var/run/php/my.site.sock;

JavaScript Sound Manager:

Try using double quotes and keeping the L in location lowercase...

header("location: http://linkhere.com/HERE_I_WANT_THE_VARIABLE");

or for example

header("location: http://linkhere.com/$variable");

No need to concatenate here to insert variables.

I found a not-so-good solution for this in case you are using a HorizontalListView, since dividers don't seem to work with it, but I think it'll work either way for the more common ListView.

Just adding:

<View
android:layout_marginBottom="xx dp/sp"/>

in the bottomest View of the Layout you inflate in the adapter class will create spacing between items

To solve Google security, do this:

Lines to the top:

import android.webkit.SslErrorHandler;
import android.net.http.SslError;

Code:

class SSLTolerentWebViewClient extends WebViewClient {
    @Override
    public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
        if (error.toString() == "piglet")
            handler.cancel();
        else
            handler.proceed(); // Ignore SSL certificate errors
    }
}

The wiki is talking from a forked repo point of view. You have access to pull and push from origin, which will be your fork of the main diaspora repo. To pull in changes from this main repo, you add a remote, "upstream" in your local repo, pointing to this original and pull from it.

So "origin" is a clone of your fork repo, from which you push and pull. "Upstream" is a name for the main repo, from where you pull and keep a clone of your fork updated, but you don't have push access to it.

Here is a fully working example based on Adam Gawne-Cain's earlier Posting. His solution is simple and actually works exceptionally well.

I've used the following text in a Grid of multiple Fields:

H__|__WWW__+__XXXX__+__WWW__|__H

this makes it possible to easily verify the x/y alignment of the hinted text.

A couple of observations:
- there are any number of solutions out there, but many only work superficially and/or are buggy
- sun.tools.jconsole.ThreadTab.PromptingTextField is a simple solution, but it only shows the prompting text when the Field doesn't have the focus & it's private, but nothing a little cut-and-paste won't fix.

The following works on JDK 8 and upwards:

import java.awt.*;
import java.util.stream.*;
import javax.swing.*;

If you use input property databinding with a JavaScript reference type (e.g., Object, Array, Date, etc.), then the parent and child will both have a reference to the same/one object. Any changes you make to the shared object will be visible to both parent and child.

In the parent's template:

<child [aList]="sharedList"></child>

In the child:

@Input() aList;
...
updateList() {
    this.aList.push('child');
}

If you want to add items to the list upon construction of the child, use the ngOnInit() hook (not the constructor(), since the data-bound properties aren't initialized at that point):

ngOnInit() {
    this.aList.push('child1')
}

This Plunker shows a working example, with buttons in the parent and child component that both modify the shared list.

Note, in the child you must not reassign the reference. E.g., don't do this in the child: this.aList = someNewArray; If you do that, then the parent and child components will each have references to two different arrays.

If you want to share a primitive type (i.e., string, number, boolean), you could put it into an array or an object (i.e., put it inside a reference type), or you could emit() an event from the child whenever the primitive value changes (i.e., have the parent listen for a custom event, and the child would have an EventEmitter output property. See @kit's answer for more info.)

Update 2015/12/22: the heavy-loader example in the Structural Directives guides uses the technique I presented above. The main/parent component has a logs array property that is bound to the child components. The child components push() onto that array, and the parent component displays the array.

Getting into a non-password protected Java keystore and changing the password can be done with a help of Java programming language itself.

You can't move the mouse pointer using javascript, and thus for obvious security reasons. The best way to achieve this effect would be to actually place the control under the mouse pointer.

Solved!

$a['index'] = [];
$a['index'][] = 'another value';
$a['index'][] = 'another value';
$a['index'][] = 'another value';
$a['index'][] = 'another value';

UNIX filesystems (generally) don't store creation times. Instead, there are only access time, (data) modification time, and (inode) change time.

That being said, find has -atime -mtime -ctime predicates:

$ man 1 find
...
-ctime  n
        The primary shall evaluate as true if the time of last change of
        file status information subtracted from the initialization time,
        divided by 86400 (with any remainder discarded), is n.
...

Thus find -ctime 0 finds everything for which the inode has changed (e.g. includes file creation, but also counts link count and permissions and filesize change) less than an hour ago.

What @Nilsi mentioned is perfectly correct. However, adminclass and user class need to be wrapped in single quotes as this might fail due to Thymeleaf looking for adminClass or userclass variables which should be strings. That said,

it should be: -

 <a href="" class="baseclass" th:classappend="${isAdmin} ? 'adminclass' : 
 'userclass'"> 
 </a>

or just:

<a href="" th:class="${isAdmin} ? 'newclass' : 
  'baseclass'"> 
 </a>

In java System.out.println() prints something to console. In javascript same can be achieved using console.log().

You need to view browser console by pressing F12 key which opens developer tool and then switch to console tab.

Apparently mine is that Haskell has variables. This is both "trivial" (according to at least eight SO users) (though nobody can seem to agree on which trivial answer is correct), and a bad question even to ask (according to at least five downvoters and four who voted to close it). Oh, and I (and computing scientests and mathematicians) am wrong, though nobody can provide me a detailed explanation of why.

You just need to use the socket settimeout() method before attempting the connect(), please note that after connecting you must settimeout(None) to set the socket into blocking mode, such is required for the makefile . Here is the code I am using:

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(10)
sock.connect(address)
sock.settimeout(None)
fileobj = sock.makefile('rb', 0)

Use dates.tolist() to convert to native datetime objects, then simply access year. Example:

>>> dates = np.array(['2010-10-17', '2011-05-13', '2012-01-15'], dtype='datetime64')
>>> [x.year for x in dates.tolist()]
[2010, 2011, 2012]

This is basically the same idea exposed in https://stackoverflow.com/a/35281829/2192272, but using simpler syntax.

Tested with python 3.6 / numpy 1.18.

You can do it in a few lines, just override onPostExecute when you call your AsyncTask. Here is an example for you:

new AasyncTask()
{
    @Override public void onPostExecute(String result)
    {
       // do whatever you want with result 
    }
}.execute(a.targetServer);

I hope it helped you, happy codding :)

I'm trying Ion_Auth and appreciate it, btw...

SimpleLoginSecure Makes authentication simple and secure.

@PathVariable - must be placed in the endpoint uri and access the query parameter value from the request
@RequestParam - must be passed as method parameter (optional based on the required property)
 http://localhost:8080/employee/call/7865467

 @RequestMapping(value=“/call/{callId}", method = RequestMethod.GET)
 public List<Calls> getAgentCallById(
            @PathVariable(“callId") int callId,
            @RequestParam(value = “status", required = false) String callStatus) {

    }

http://localhost:8080/app/call/7865467?status=Cancelled

}

You can read here about the behaviour of attributes in many different browsers, including IE.

element.setAttribute() should do the trick, even in IE. Did you try it? If it doesn't work, then maybe element.attributeName = 'value' might work.

If you don't mind using sed then,

$ cat test 
this is line 1
$ sed -i '$ a\this is line 2 without redirection' test 
$ cat test 
this is line 1
this is line 2 without redirection

As the documentation may be a bit long to go through, some explanations :

• -i means an inplace transformation, so all changes will occur in the file you specify
• $ is used to specify the last line
• a means append a line after
• \ is simply used as a delimiter

I was able to get a great solution to this problem with iScroll, with the feel of momentum scrolling and everything https://github.com/cubiq/iscroll The github doc is great, and I mostly followed it. Here's the details of my implementation.

HTML: I wrapped the scrollable area of my content in some divs that iScroll can use:

<div id="wrapper">
  <div id="scroller">
    ... my scrollable content
  </div>
</div>

CSS: I used the Modernizr class for "touch" to target my style changes only to touch devices (because I only instantiated iScroll on touch).

.touch #wrapper {
  position: absolute;
  z-index: 1;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  overflow: hidden;
}
.touch #scroller {
  position: absolute;
  z-index: 1;
  width: 100%;
}

JS: I included iscroll-probe.js from the iScroll download, and then initialized the scroller as below, where updatePosition is my function that reacts to the new scroll position.

# coffeescript
if Modernizr.touch
  myScroller = new IScroll('#wrapper', probeType: 3)
  myScroller.on 'scroll', updatePosition
  myScroller.on 'scrollEnd', updatePosition

You have to use myScroller to get the current position now, instead of looking at the scroll offset. Here is a function taken from http://markdalgleish.com/presentations/embracingtouch/ (a super helpful article, but a little out of date now)

function getScroll(elem, iscroll) {   
  var x, y;

  if (Modernizr.touch && iscroll) {
    x = iscroll.x * -1;
    y = iscroll.y * -1;   
  } else {
    x = elem.scrollTop;
    y = elem.scrollLeft;   
  }

  return {x: x, y: y}; 
}

The only other gotcha was occasionally I would lose part of my page that I was trying to scroll to, and it would refuse to scroll. I had to add in some calls to myScroller.refresh() whenever I changed the contents of the #wrapper, and that solved the problem.

EDIT: Another gotcha was that iScroll eats all the "click" events. I turned on the option to have iScroll emit a "tap" event and handled those instead of "click" events. Thankfully I didn't need much clicking in the scroll area, so this wasn't a big deal.

If you want to start afresh, deleting the settings.json file from your user's profile will do the trick.

But if you don't want to reset everything, it is still possible through settings menu.

You can search for the setting that you want to revert back using search box.

You will see some settings with the left blue line, it means you've modified that one.

If you take your cursor to that setting, a gear button will appear. You can click this to restore that setting.

You can also use the drop-down below that setting and change it to default.

After some investigation, I found the final and the most easy way is to extend BaseRequestOptions which I prefer.
The following are the ways I tried and give up for some reason:
1. extend BaseRequestOptions, and add dynamic headers in constructor(). It can not work if I login. It will be created once. So it is not dynamic.
2. extend Http. Same reason as above, I can not add dynamic headers in constructor(). And if I rewrite request(..) method, and set headers, like this:

request(url: string|Request, options?: RequestOptionsArgs): Observable<Response> {
 let token = localStorage.getItem(AppConstants.tokenName);
 if (typeof url === 'string') { // meaning we have to add the token to the options, not in url
  if (!options) {
    options = new RequestOptions({});
  }
  options.headers.set('Authorization', 'token_value');
 } else {
  url.headers.set('Authorization', 'token_value');
 }
 return super.request(url, options).catch(this.catchAuthError(this));
}

You just need to overwrite this method, but not every get/post/put methods.

3.And my preferred solution is extend BaseRequestOptions and overwrite merge() :

@Injectable()
export class AuthRequestOptions extends BaseRequestOptions {

 merge(options?: RequestOptionsArgs): RequestOptions {
  var newOptions = super.merge(options);
  let token = localStorage.getItem(AppConstants.tokenName);
  newOptions.headers.set(AppConstants.authHeaderName, token);
  return newOptions;
 }
}

this merge() function will be called for every request.

In Tomcat 8.0.44 I did this: create the JNDI on Tomcat's server.xml between the tag "GlobalNamingResources" For example:

<GlobalNamingResources>_x000D_
    <!-- Editable user database that can also be used by_x000D_
         UserDatabaseRealm to authenticate users_x000D_
    -->_x000D_
  <!-- Other previus resouces -->_x000D_
    <Resource auth="Container" driverClassName="org.postgresql.Driver" global="jdbc/your_jndi" _x000D_
    maxActive="100" maxIdle="20" maxWait="1000" minIdle="5" name="jdbc/your_jndi" password="your_password" _x000D_
    type="javax.sql.DataSource" url="jdbc:postgresql://localhost:5432/your_database?user=postgres" username="database_username"/>_x000D_
  </GlobalNamingResources>

<?xml version="1.0" encoding="UTF-8"?>_x000D_
<Context reloadable="true" >_x000D_
   <ResourceLink name="jdbc/your_jndi"_x000D_
      global="jdbc/your_jndi"_x000D_
      auth="Container"_x000D_
      type="javax.sql.DataSource" />_x000D_
</Context>

So if you're using Hiberte with spring you can tell to him to use the JNDI in your persistence.xml

<?xml version="1.0" encoding="UTF-8"?>_x000D_
<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"_x000D_
 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"_x000D_
 version="2.0" xmlns="http://java.sun.com/xml/ns/persistence">_x000D_
 <persistence-unit name="UNIT_NAME" transaction-type="RESOURCE_LOCAL">_x000D_
  <provider>org.hibernate.ejb.HibernatePersistence</provider>_x000D_
_x000D_
  <properties>_x000D_
   <property name="javax.persistence.jdbc.driver"   value="org.postgresql.Driver" />_x000D_
   <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQL82Dialect" />_x000D_
   _x000D_
   <!--  <property name="hibernate.jdbc.time_zone" value="UTC"/>-->_x000D_
   <property name="hibernate.hbm2ddl.auto" value="update" />_x000D_
   <property name="hibernate.show_sql" value="false" />_x000D_
   <property name="hibernate.format_sql" value="true"/>     _x000D_
  </properties>_x000D_
 </persistence-unit>_x000D_
</persistence>

So in your spring.xml you can do that:

<bean id="postGresDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">_x000D_
   <property name="jndiName" value="java:comp/env/jdbc/your_jndi" />_x000D_
  </bean>_x000D_
     _x000D_
        <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">_x000D_
              <property name="persistenceUnitName" value="UNIT_NAME" />_x000D_
              <property name="dataSource" ref="postGresDataSource" />_x000D_
              <property name="jpaVendorAdapter"> _x000D_
                 <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />_x000D_
              </property>_x000D_
        </bean>

<property name="jndiName" value="java:comp/env/jdbc/your_jndi" />

In this example I used spring with xml but you can do this programmaticaly if you prefer.

That's it, I hope helped.

Not in PHP.
phpinfo(32) contains everything PHP able to know about particular client, and there is no [windows] computer name

Use count(d.ertek) or count(d.id) instead of count(d). This can be happen when you have composite primary key at your entity.

Your results will not be helpful unless the arrays are first sorted. To sort an array, run it through Sort-Object.

$x = @(5,1,4,2,3)
$y = @(2,4,6,1,3,5)

Compare-Object -ReferenceObject ($x | Sort-Object) -DifferenceObject ($y | Sort-Object)

try this

int intIdt = db.Users.Max(u => u.UserId);

Update:

If no record then generate exception using above code try this

int? intIdt = db.Users.Max(u => (int?)u.UserId);

I have encountered the same error on ubuntu and what worked for me was editing 2 lines in /etc/php/7.3/apache2/php.ini

  ;extension=mysqli to   extension=mysqli

and gave the extension variable location to mysqli.so after uncommenting it

   extension=/usr/lib/php/20170718/mysqli.so

then restart the service just to make sure

systemctl start mysql

Don't use the border attribute, use CSS for all your styling needs.

<table style="border:1px; width:100%;">
    <tr>
            <th style="width:15%;">From</th>
            <th style="width:70%;">Subject</th>
            <th style="width:15%;">Date</th>
    </tr>
... rest of the table code...

But embedding CSS like that is poor practice - one should use CSS classes instead, and put the CSS rules in an external CSS file.

strip does nothing but, removes the the whitespace in your string. If you want to remove the extra whitepace from front and back of your string, you can use strip.

The example string which can illustrate that is this:

In [2]: x = "something \t like     \t this"
In [4]: x.split('\t')
Out[4]: ['something ', ' like     ', ' this']

See, even after splitting with \t there is extra whitespace in first and second items which can be removed using strip in your code.

This was extremely helpful for me when trying to automate Cisco SIP phone configuration using an Excel spreadsheet as the source. My only issue was when I tried to make an array and populate it using $array | Add-Member ... as I needed to use it later on to generate the config file. Just defining an array and making it the for loop allowed it to store correctly.

$lastCell = 11 
$startRow, $model, $mac, $nOF, $ext = 1, 1, 5, 6, 7

$excel = New-Object -ComObject excel.application
$wb = $excel.workbooks.open("H:\Strike Network\Phones\phones.xlsx")
$sh = $wb.Sheets.Item(1)
$endRow = $sh.UsedRange.SpecialCells($lastCell).Row

$phoneData = for ($i=1; $i -le $endRow; $i++)
            {
                $pModel = $sh.Cells.Item($startRow,$model).Value2
                $pMAC = $sh.Cells.Item($startRow,$mac).Value2
                $nameOnPhone = $sh.Cells.Item($startRow,$nOF).Value2
                $extension = $sh.Cells.Item($startRow,$ext).Value2
                New-Object PSObject -Property @{ Model = $pModel; MAC = $pMAC; NameOnPhone = $nameOnPhone; Extension = $extension }
                $startRow++
            }

I used to have no issues adding information to an array with Add-Member but that was back in PSv2/3, and I've been away from it a while. Though the simple solution saved me manually configuring 100+ phones and extensions - which nobody wants to do.

du -sm * | sort -nr

Output by size

Here's a variant of the solution from @JoshuaUlrich that uses the correct size instead of a hard-coded size:

fileName <- 'foo.txt'
readChar(fileName, file.info(fileName)$size)

Note that readChar allocates space for the number of bytes you specify, so readChar(fileName, .Machine$integer.max) does not work well...

This is my favorite solution for SQL 2008 , which puts the results into a "TEST" temp table that I can use to sort and get the results that I need :

SET NOCOUNT ON 
DBCC UPDATEUSAGE(0) 
DROP TABLE #t;
CREATE TABLE #t 
( 
[name] NVARCHAR(128),
[rows] CHAR(11),
reserved VARCHAR(18), 
data VARCHAR(18), 
index_size VARCHAR(18),
unused VARCHAR(18)
) ;
INSERT #t EXEC sp_msForEachTable 'EXEC sp_spaceused ''?''' 
SELECT * INTO TEST FROM #t;
DROP TABLE #t;
SELECT  name, [rows], reserved, data, index_size, unused FROM TEST \
WHERE ([rows] > 0) AND (name LIKE 'XXX%')

I wrote serialijse because I faced the same problem as you.

you can find it at https://github.com/erossignon/serialijse

It can be used in nodejs or in a browser and can serve to serialize and deserialize a complex set of objects from one context (nodejs) to the other (browser) or vice-versa.

    </tr>
    <tr>

        <td>@Html.DropDownListFor(x =>x.Province,SelectListItemHelper.GetProvincesList())<span class="required">*</span></td>
    </tr>

Created a Controller under "UTIL" folder: Code:-

using System;

I don't know if anyone is still following this thread, but I recently had this issue when I tried to launch ActiveMQ 5.10 as a Windows service.

I didn't have a JAVA_HOME path set. I had Java 6 and Java 7 installed, but the default version was v7. (ie if I opened a command window and types "java -version").

This is where the clue was - "java -version" returned "Java HotSpot(TM) 64-Bit Server VM (build 23.1-b03, mixed mode)" but I was had installed the Win32 service...

It turns out that if you use the Win32 wrapper on a 64-bit machine it somehow decides to use a different version of Java...

So my fix was to uninstall the 32-bit version of the wrapper and install the 64-bit version. aversion on my machine; just habit I guess... But luckily I resolved the issue eventually...

Define a behavior in your .config file:

<configuration>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="debug">
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    ...
  </system.serviceModel>
</configuration>

Then apply the behavior to your service along these lines:

<configuration>
  <system.serviceModel>
    ...
    <services>
      <service name="MyServiceName" behaviorConfiguration="debug" />
    </services>
  </system.serviceModel>
</configuration>

You can also set it programmatically. See this question.

This error is generic of the security libraries and might happen in other cases. In case other people have this same error when sending emails with javax.mail to a smtp server. Then the code to force other protocol is setting a property like this:

prop.put("mail.smtp.ssl.protocols", "TLSv1.2");            

//And just in case probably you need to set these too
prop.put("mail.smtp.starttls.enable", true);    
prop.put("mail.smtp.ssl.trust", {YOURSERVERNAME});

I cannot help you much without a small (possibly reduced) snippit of the problem. If the problem is what I think it is then it's because a div by default takes up 100% width, and as such cannot be aligned.

What you may be after is to align the inline elements inside the div (such as text) with text-align:center; otherwise you may consider setting the div to display:inline-block;

If you do go down the inline-block route then you may have to consider my favorite IE hack.

width:100px;
display:inline-block;
zoom:1; //IE only
*display:inline; //IE only

Happy Coding :)

I solved this issue by changing the permission of my npm directory. I went to the npm global directory for me it was at

/home/<user-name>

I went to this directory by entering this command

cd /home/<user-name>

and then changed the permission of .npm folder by entering this command.

sudo chmod -R 777 ".npm"

It worked like a charm to me. But there is a security flaw with this i.e your global packages directory is accessible to all the levels.

In PHP you can try this:

$query = mysql_query("SELECT MAX(id) FROM `your_table_name`");
$results = mysql_fetch_array($query);
$cur_auto_id = $results['MAX(id)'] + 1;

OR

$result = mysql_query("SHOW TABLE STATUS WHERE `Name` = 'your_table_name'");
$data = mysql_fetch_assoc($result);
$next_increment = $data['Auto_increment'];

I was getting the same messages while I was running just msbuild from powershell.

dotnet msbuild "./project.csproj" worked for me.

Use order function:

set.seed(1)
DF <- data.frame(ID= sample(letters[1:26], 15, TRUE),
                 num = sample(1:100, 15, TRUE),
                 random = rnorm(15),
                 stringsAsFactors=FALSE)
DF[order(DF[,'ID']), ]
   ID num      random
10  b  27  0.61982575
12  e   2 -0.15579551
5   f  78  0.59390132
11  f  39 -0.05612874
1   g  50 -0.04493361
2   j  72 -0.01619026
14  j  87 -0.47815006
3   o 100  0.94383621
9   q  13 -1.98935170
8   r  66  0.07456498
13  r  39 -1.47075238
15  u  35  0.41794156
4   x  39  0.82122120
6   x  94  0.91897737
7   y  22  0.78213630

Another solution would be using orderByfunction from doBy package:

> library(doBy)
> orderBy(~ID, DF)

I have suffered the same issue and was able to solve it by simply changing on my Android device (Nexus 5X) in Developer options > Select USB Configuration to RNDIS (USB Ethernet)

The web.config transforms that are part of Visual Studio 2010 use XSLT in order to "transform" the current web.config file into its .Debug or .Release version.

In your .Debug/.Release files, you need to add the following parameter in your connection string fields:

xdt:Transform="SetAttributes" xdt:Locator="Match(name)"

This will cause each connection string line to find the matching name and update the attributes accordingly.

Note: You won't have to worry about updating your providerName parameter in the transform files, since they don't change.

Here's an example from one of my apps. Here's the web.config file section:

<connectionStrings>
      <add name="EAF" connectionString="[Test Connection String]" />
</connectionString>

And here's the web.config.release section doing the proper transform:

<connectionStrings>
      <add name="EAF" connectionString="[Prod Connection String]"
           xdt:Transform="SetAttributes"
           xdt:Locator="Match(name)" />
</connectionStrings>

One added note: Transforms only occur when you publish the site, not when you simply run it with F5 or CTRL+F5. If you need to run an update against a given config locally, you will have to manually change your Web.config file for this.

For more details you can see the MSDN documentation

https://msdn.microsoft.com/en-us/library/dd465326(VS.100).aspx

Json.NET allows us to do this:

dynamic d = JObject.Parse("{number:1000, str:'string', array: [1,2,3,4,5,6]}");

Console.WriteLine(d.number);
Console.WriteLine(d.str);
Console.WriteLine(d.array.Count);

Output:

 1000

I know this is 3 years too late, but Matt's (accepted) answer is incomplete and will eventually get you into trouble. The key here is that, if you choose to use multipart/form-data, the boundary must not appear in the file data that the server eventually receives.

This is not a problem for application/x-www-form-urlencoded, because there is no boundary. x-www-form-urlencoded can also always handle binary data, by the simple expedient of turning one arbitrary byte into three 7BIT bytes. Inefficient, but it works (and note that the comment about not being able to send filenames as well as binary data is incorrect; you just send it as another key/value pair).

The problem with multipart/form-data is that the boundary separator must not be present in the file data (see RFC 2388; section 5.2 also includes a rather lame excuse for not having a proper aggregate MIME type that avoids this problem).

So, at first sight, multipart/form-data is of no value whatsoever in any file upload, binary or otherwise. If you don't choose your boundary correctly, then you will eventually have a problem, whether you're sending plain text or raw binary - the server will find a boundary in the wrong place, and your file will be truncated, or the POST will fail.

The key is to choose an encoding and a boundary such that your selected boundary characters cannot appear in the encoded output. One simple solution is to use base64 (do not use raw binary). In base64 3 arbitrary bytes are encoded into four 7-bit characters, where the output character set is [A-Za-z0-9+/=] (i.e. alphanumerics, '+', '/' or '='). = is a special case, and may only appear at the end of the encoded output, as a single = or a double ==. Now, choose your boundary as a 7-bit ASCII string which cannot appear in base64 output. Many choices you see on the net fail this test - the MDN forms docs, for example, use "blob" as a boundary when sending binary data - not good. However, something like "!blob!" will never appear in base64 output.

I come here some years after, and I could fix it thanks to atrain's comment above. In my case, I was missing @Valid in the API that receives the Object (a POJO in my case) that was annotated with @Size. It solved the issue.

I did not need to add any extra annotation, such as @Valid or @NotBlank to the variable annotated with @Size, just that constraint in the variable and what I mentioned in the API...

Pojo Class:

...
@Size(min = MIN_LENGTH, max = MAX_LENGTH);
private String exampleVar;
...

API Class:

...
public void exampleApiCall(@RequestBody @Valid PojoObject pojoObject){
  ...
}

Thanks and cheers

And this is less

@primarycolor: #ffffff;
@width: 800px;

body{
 width: @width;
 color: @primarycolor;
 .content{
  width: @width;
  background:@primarycolor;
 }
}

The following characters must be escaped in JSON data to avoid any problems:

• " (double quote)
• \ (backslash)
• all control characters like \n, \t

JSON Parser can help you to deal with JSON.

The other answers here were missing one crucial step for me. In AndroidManifest.xml I needed to add usesCleartextTraffic:

    <application
      ...
      android:usesCleartextTraffic="true">

You probably don't want to keep this in the production release of your app though, unless you want to support insecure http requests.

After I added this to my AndroidManifest.xml, then I followed Tom Aranda's answer, and the emulator was finally able to connect to the debugger.

For older .xls files, you can use xlrd

either you can use xlrd directly by importing it. Like below

import xlrd
wb = xlrd.open_workbook(file_name)

Or you can also use pandas pd.read_excel() method, but do not forget to specify the engine, though the default is xlrd, it has to be specified.

pd.read_excel(file_name, engine = xlrd)

Both of them work for older .xls file formats. Infact I came across this when I used OpenPyXL, i got the below error

InvalidFileException: openpyxl does not support the old .xls file format, please use xlrd to read this file, or convert it to the more recent .xlsx file format.

When you use re.split and the split pattern contains capturing groups, the groups are retained in the output. If you don't want this, use a non-capturing group instead.

Ideally, every custom watch should be removed when you leave the scope.

It helps in better memory management and better app performance.

// call to $watch will return a de-register function
var listener = $scope.$watch(someVariableToWatch, function(....));

$scope.$on('$destroy', function() {
    listener(); // call the de-register function on scope destroy
});

Use the drive letter with forward slashes to get started (c:/apache/...).

An alternative approach would be:

df1 = sqlContext.createDataFrame(
    [(1, "a", 2.0), (2, "b", 3.0), (3, "c", 3.0)],
    ("x1", "x2", "x3"))

df2 = sqlContext.createDataFrame(
    [(1, "f", -1.0), (2, "b", 0.0)], ("x1", "x2", "x4"))

df = df1.join(df2, ['x1','x2'])
df.show()

which outputs:

+---+---+---+---+
| x1| x2| x3| x4|
+---+---+---+---+
|  2|  b|3.0|0.0|
+---+---+---+---+

With the main advantage being that the columns on which the tables are joined are not duplicated in the output, reducing the risk of encountering errors such as org.apache.spark.sql.AnalysisException: Reference 'x1' is ambiguous, could be: x1#50L, x1#57L.

Whenever the columns in the two tables have different names, (let's say in the example above, df2 has the columns y1, y2 and y4), you could use the following syntax:

df = df1.join(df2.withColumnRenamed('y1','x1').withColumnRenamed('y2','x2'), ['x1','x2'])

NSMutableDictionary *contentDictionary = [[NSMutableDictionary alloc]init];
        [contentDictionary setValue:@"a" forKey:@"b"];
        [contentDictionary setValue:@"c" forKey:@"d"];
        NSData *data = [NSJSONSerialization dataWithJSONObject:contentDictionary options:NSJSONWritingPrettyPrinted error:nil];
        NSString *jsonStr = [[NSString alloc] initWithData:data
                                                  encoding:NSUTF8StringEncoding];

I Had the same problem, in my case, was because i was returned a digit:

def __str__(self):
    return self.code

str is waiting for a str, not another.

now work good with:

def __str__(self):
    return self.name

where name is a STRING.

Show them that the base-10 system suffers from exactly the same problem.

Try to represent 1/3 as a decimal representation in base 10. You won't be able to do it exactly.

So if you write "0.3333", you will have a reasonably exact representation for many use cases.

But if you move that back to a fraction, you will get "3333/10000", which is not the same as "1/3".

Other fractions, such as 1/2 can easily be represented by a finite decimal representation in base-10: "0.5"

Now base-2 and base-10 suffer from essentially the same problem: both have some numbers that they can't represent exactly.

While base-10 has no problem representing 1/10 as "0.1" in base-2 you'd need an infinite representation starting with "0.000110011..".

change the CSS as follows:

div button {
position:absolute;
    right:10px;
    top:25px;
}

If you only want to have glyphicons icons without any additional css you can create a css file and put the code below and include it into main css file.

I have to create this extra file as link below was messing with my site styles too.

Instead to using it directly I created a css file bootstrap-glyphicons.css

@font-face{font-family:'Glyphicons Halflings';src:url('http://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.eot');src:url('http://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'),url('http://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.woff') format('woff'),url('http://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.ttf') format('truetype'),url('http://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');}.glyphicon{position:relative;top:1px;display:inline-block;font-family:'Glyphicons Halflings';font-style:normal;font-weight:normal;line-height:1;-webkit-font-smoothing:antialiased;}_x000D_

And imported the created css file into my main css file which enable me to just import the glyphicons only. Hope this help

@import url("bootstrap-glyphicons.css");

This is a very simple and clear solution
Two lines of code

# First we obtain de timezone info o some datatime variable    

tz_info = your_timezone_aware_variable.tzinfo

# Now we can subtract two variables using the same time zone info
# For instance
# Lets obtain the Now() datetime but for the tz_info we got before

diff = datetime.datetime.now(tz_info)-your_timezone_aware_variable

Conclusion: You must mange your datetime variables with the same time info

If you grep the command that you are looking for with a pipe from ps aux, it will wrap the text automatically. I used a lot of the other answers on here, but sometimes if you are looking for something specific, it is nice to just use grep and you know that it will wrap lines.

For instance ps aux | grep ffmpeg .

Ok, I figured it out. The issue was that I didn't have the correct permissions set for myrepo.git and the parent directory git.

As root I logged into the server and used:

$ chown username /home/username/git

This then returns drwxrwxr-x 4 username root 4096 2012-10-30 15:51 /home/username/git with the following:

$ ls -ld /home/username/git

I then make a new directory for myrepo.git inside git:

$ mkdir myrepo.git
$ ls -ld myrepo.git/
drwxr-xr-x 2 root root 4096 2012-10-30 18:41 myrepo.git/

but it has the user set to root, so I change it to username the same way as before.

$ chown username myrepo.git/
$ ls -ld myrepo.git/
drwxr-xr-x 2 username root 4096 2012-10-30 18:41 myrepo.git/

I then sign out of root and sign into server as username:

Inside git directory:

$ cd myrepo.git/
$ git --bare init
Initialized empty Git repository in /home/username/git/myrepo.git/

On local machine:

$ git remote add origin      
ssh://[email protected]/home/username/git/myrepo.git
$ git push origin master

SUCCESS!

Hopefully this comes in handy for anyone else that runs into the same issue in the future!

You'll have to write the SQL DML yourself explicitly. i.e.

UPDATE <table>
   SET <column> = NULL;

Once it has completed you'll need to commit your updates

commit;

If you only want to set certain records to NULL use a WHERE clause in your UPDATE statement.

As your original question is pretty vague I hope this covers what you want.

<?php wp_make_link_relative( $link ) ?>

Convert full URL paths to relative paths.

Removes the http or https protocols and the domain. Keeps the path '/' at the beginning, so it isn't a true relative link, but from the web root base.

If we want to assign a scaler value eg: 10 to all rows of a new column in a df:

df = df.assign(new_col=lambda x:10)  # x is each row passed in to the lambda func

df will now have new column 'new_col' with value=10 in all rows.

As suggested you need to use ng-options and unfortunately I believe you need to reference the array element for a default (unless the array is an array of strings).

http://jsfiddle.net/FxM3B/3/

The JavaScript:

function AppCtrl($scope) {


    $scope.operators = [
        {value: 'eq', displayName: 'equals'},
        {value: 'neq', displayName: 'not equal'}
     ]

    $scope.filterCondition={
        operator: $scope.operators[0]
    }
}

The HTML:

<body ng-app ng-controller="AppCtrl">
<div>Operator is: {{filterCondition.operator.value}}</div>
<select ng-model="filterCondition.operator" ng-options="operator.displayName for operator in operators">
</select>
</body>

You can customise the credits, changing the URL, text, Position etc. All the info is documented here: http://api.highcharts.com/highcharts/credits. To simply disable them altogether, use:

credits: {
    enabled: false
},

In addition to existing answers it is often desired to format the REST output (typically JSON and XML lacks indentation). Try this:

$ curl https://api.twitter.com/1/help/configuration.xml  | xmllint --format -
$ curl https://api.twitter.com/1/help/configuration.json | python -mjson.tool

Tested on Ubuntu 11.0.4/11.10.

Another issue is the desired content type. Twitter uses .xml/.json extension, but more idiomatic REST would require Accept header:

$ curl -H "Accept: application/json"

By using Server.Transfer("YourCurrentPage.aspx"); we can easily acheive this and it is better than Response.Redirect(); coz Server.Transfer() will save you the round trip.

To get the last date of the month we do something like this:

from datetime import date, timedelta
import calendar
last_day = date.today().replace(day=calendar.monthrange(date.today().year, date.today().month)[1])

Now to explain what we are doing here we will break it into two parts:

first is getting the number of days of the current month for which we use monthrange which Blair Conrad has already mentioned his solution:

calendar.monthrange(date.today().year, date.today().month)[1]

second is getting the last date itself which we do with the help of replace e.g

>>> date.today()
datetime.date(2017, 1, 3)
>>> date.today().replace(day=31)
datetime.date(2017, 1, 31)

and when we combine them as mentioned on the top we get a dynamic solution.

Basically, pip comes with python itself.Therefore it carries no meaning for using pip itself to install or upgrade python. Thus,try to install python through installer itself,visit the site "https://www.python.org/downloads/" for more help. Thank you.

XML Schema requires that the xml namespace be declared and imported before using xml:lang (and other xml namespace values) RELAX NG predeclares the xml namespace, as in XML, so no additional declaration is needed.

In order to make numpy display float arrays in an arbitrary format, you can define a custom function that takes a float value as its input and returns a formatted string:

In [1]: float_formatter = "{:.2f}".format

The f here means fixed-point format (not 'scientific'), and the .2 means two decimal places (you can read more about string formatting here).

Let's test it out with a float value:

In [2]: float_formatter(1.234567E3)
Out[2]: '1234.57'

To make numpy print all float arrays this way, you can pass the formatter= argument to np.set_printoptions:

In [3]: np.set_printoptions(formatter={'float_kind':float_formatter})

Now numpy will print all float arrays this way:

In [4]: np.random.randn(5) * 10
Out[4]: array([5.25, 3.91, 0.04, -1.53, 6.68]

Note that this only affects numpy arrays, not scalars:

In [5]: np.pi
Out[5]: 3.141592653589793

It also won't affect non-floats, complex floats etc - you will need to define separate formatters for other scalar types.

You should also be aware that this only affects how numpy displays float values - the actual values that will be used in computations will retain their original precision.

For example:

In [6]: a = np.array([1E-9])

In [7]: a
Out[7]: array([0.00])

In [8]: a == 0
Out[8]: array([False], dtype=bool)

numpy prints a as if it were equal to 0, but it is not - it still equals 1E-9.

If you actually want to round the values in your array in a way that affects how they will be used in calculations, you should use np.round, as others have already pointed out.

The easiest way to do it is leaving action blank action="" or omitting it completely from the form tag, however it is bad practice (if at all you care about it).

Incase you do care about it, the best you can do is:

<form name="form1" id="mainForm" method="post" enctype="multipart/form-data" action="<?php echo($_SERVER['PHP_SELF'] . http_build_query($_GET));?>">

The best thing about using this is that even arrays are converted so no need to do anything else for any kind of data.

select right(rtrim('94342KMR'),3)

This will fetch the last 3 right string.

select substring(rtrim('94342KMR'),1,len('94342KMR')-3)

This will fetch the remaining Characters.

If you want to get stored procedures using specific column only, you can use try this query:

SELECT DISTINCT Name
FROM sys.Procedures
WHERE object_definition(OBJECT_ID) LIKE '%CreatedDate%';

If you want to get stored procedures using specific column of table, you can use below query :

SELECT DISTINCT Name 
FROM sys.procedures
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%tbl_name%'
AND OBJECT_DEFINITION(OBJECT_ID) LIKE '%CreatedDate%';

Decimal representation of floating point numbers is kind of strange. If you have a number with 15 decimal places and convert that to a double, then print it out with exactly 15 decimal places, you should get the same number. On the other hand, if you print out an arbitrary double with 15 decimal places and the convert it back to a double, you won't necessarily get the same value back—you need 17 decimal places for that. And neither 15 nor 17 decimal places are enough to accurately display the exact decimal equivalent of an arbitrary double. In general, you need over 100 decimal places to do that precisely.

See the Wikipedia page for double-precision and this article on floating-point precision.

In base R, we can select the columns which we want to test using grep, compare the data with 0, use rowSums to select rows which has all non-zero values.

cols <- grep("^Mac", names(df))
df[rowSums(df[cols] != 0) == length(cols), ]

#          DateTime Mac1 Mac2 Mac3 Mac4
#1 2011-04-02 06:05   21   21   21   21
#2 2011-04-02 06:10   22   22   22   22
#3 2011-04-02 06:20   24   24   24   24

Doing this with inverted logic but giving the same output

df[rowSums(df[cols] == 0) == 0, ]

In dplyr, we can use filter_at to test for specific columns and use all_vars to select rows where all the values are not equal to 0.

library(dplyr)
df %>%  filter_at(vars(starts_with("Mac")), all_vars(. != 0))

data

df <- structure(list(DateTime = structure(1:6, .Label = c("2011-04-02 06:00", 
"2011-04-02 06:05", "2011-04-02 06:10", "2011-04-02 06:15", "2011-04-02 06:20", 
"2011-04-02 06:25"), class = "factor"), Mac1 = c(20L, 21L, 22L, 
23L, 24L, 0L), Mac2 = c(0L, 21L, 22L, 23L, 24L, 25L), Mac3 = c(20L, 
21L, 22L, 0L, 24L, 25L), Mac4 = c(20L, 21L, 22L, 23L, 24L, 0L
)), class = "data.frame", row.names = c(NA, -6L))

Hi easiest way to do this is to convert this IEnumerable into a Queryable

If it is a queryable, then performing queries becomes easy.

Please check this code:

var result = (from s in _ctx.ScannedDatas.AsQueryable()
                              where s.Data == scanData
                              select s.Id).FirstOrDefault();
                return "Match Found";

Make sure you include System.Linq. This way your error will be resolved.

The following categories of variables are classified as initially unassigned:

• Instance variables of initially unassigned struct variables.
• Output parameters, including the this variable of struct instance constructors.
• Local variables , except those declared in a catch clause or a foreach statement.

The following categories of variables are classified as initially assigned:

• Static variables.
• Instance variables of class instances.
• Instance variables of initially assigned struct variables.
• Array elements.
• Value parameters.
• Reference parameters.
• Variables declared in a catch clause or a foreach statement.

Just use the split function. It returns a list, so you can keep the first element:

>>> s1.split(':')
['Username', ' How are you today?']
>>> s1.split(':')[0]
'Username'

Beautiful solution by @Lukasz Wiklendt! Although in my case I needed something more generic so I modified it a bit:

template <class RAIter, class Compare>
vector<size_t> argSort(RAIter first, RAIter last, Compare comp) {

  vector<size_t> idx(last-first);
  iota(idx.begin(), idx.end(), 0);

  auto idxComp = [&first,comp](size_t i1, size_t i2) {
      return comp(first[i1], first[i2]);
  };

  sort(idx.begin(), idx.end(), idxComp);

  return idx;
}

Example: Find indices sorting a vector of strings by length, except for the first element which is a dummy.

vector<string> test = {"dummy", "a", "abc", "ab"};

auto comp = [](const string &a, const string& b) {
    return a.length() > b.length();
};

const auto& beginIt = test.begin() + 1;
vector<size_t> ind = argSort(beginIt, test.end(), comp);

for(auto i : ind)
    cout << beginIt[i] << endl;

prints:

abc
ab
a

C++ is a general-purpose programming language. It is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features. It was developed by Bjarne Stroustrup starting in 1979 at Bell Labs as an enhancement to the C programming language and originally named "C with Classes". It was renamed to C++ in 1983.

C++ is widely used in the software industry. Some of its application domains include systems software, application software, device drivers, embedded software, high-performance server and client applications, and entertainment software such as video games. Several groups provide both free and proprietary C++ compiler software, including the GNU Project, Microsoft, Intel, Borland and others.

Microsoft Visual C++ (often abbreviated as MSVC or VC++) is an integrated development environment (IDE) product from Microsoft for the C, C++, and C++/CLI programming languages. MSVC is proprietary software; it was originally a standalone product but later became a part of Visual Studio and made available in both trialware and freeware forms. It features tools for developing and debugging C++ code, especially code written for Windows API, DirectX and .NET Framework.

So the main difference between them is that they are different things. The former is a programming language, while the latter is a commercial integrated development environment (IDE).

I was facing the same issue but it was not a permission issue.

When you are doing git clone it will create try to create replica of the respository structure.

When its trying to create the folder/directory with same name and path in your local os process is not allowing to do so and hence the error. There was "background" java process running in Task-manager which was accessing the resource of the directory(folder) and hence it was showing as permission denied for git operations. I have killed those process and that solved my problem. Cheers!!

Python 3 handles strings a bit different. Originally there was just one type for strings: str. When unicode gained traction in the '90s the new unicode type was added to handle Unicode without breaking pre-existing code¹. This is effectively the same as str but with multibyte support.

In Python 3 there are two different types:

• The bytes type. This is just a sequence of bytes, Python doesn't know anything about how to interpret this as characters.
• The str type. This is also a sequence of bytes, but Python knows how to interpret those bytes as characters.
• The separate unicode type was dropped. str now supports unicode.

In Python 2 implicitly assuming an encoding could cause a lot of problems; you could end up using the wrong encoding, or the data may not have an encoding at all (e.g. it’s a PNG image).
Explicitly telling Python which encoding to use (or explicitly telling it to guess) is often a lot better and much more in line with the "Python philosophy" of "explicit is better than implicit".

This change is incompatible with Python 2 as many return values have changed, leading to subtle problems like this one; it's probably the main reason why Python 3 adoption has been so slow. Since Python doesn't have static typing² it's impossible to change this automatically with a script (such as the bundled 2to3).

• You can convert str to bytes with bytes('h€llo', 'utf-8'); this should produce b'H\xe2\x82\xacllo'. Note how one character was converted to three bytes.
• You can convert bytes to str with b'H\xe2\x82\xacllo'.decode('utf-8').

Of course, UTF-8 may not be the correct character set in your case, so be sure to use the correct one.

In your specific piece of code, nextline is of type bytes, not str, reading stdout and stdin from subprocess changed in Python 3 from str to bytes. This is because Python can't be sure which encoding this uses. It probably uses the same as sys.stdin.encoding (the encoding of your system), but it can't be sure.

You need to replace:

sys.stdout.write(nextline)

with:

sys.stdout.write(nextline.decode('utf-8'))

or maybe:

sys.stdout.write(nextline.decode(sys.stdout.encoding))

You will also need to modify if nextline == '' to if nextline == b'' since:

>>> '' == b''
False

Also see the Python 3 ChangeLog, PEP 358, and PEP 3112.

¹ There are some neat tricks you can do with ASCII that you can't do with multibyte character sets; the most famous example is the "xor with space to switch case" (e.g. chr(ord('a') ^ ord(' ')) == 'A') and "set 6th bit to make a control character" (e.g. ord('\t') + ord('@') == ord('I')). ASCII was designed in a time when manipulating individual bits was an operation with a non-negligible performance impact.

² Yes, you can use function annotations, but it's a comparatively new feature and little used.

request.FILES['filename'].name

From the request documentation.

If you don't know the key, you can iterate over the files:

for filename, file in request.FILES.iteritems():
    name = request.FILES[filename].name

Simple Difference: (Inspired by Yaakov's Coursera AngularJS course)

MVC (Model View Controller)

1. Models: Models contain data information. Does not call or use Controller and View. Contains the business logic and ways to represent data. Some of this data, in some form, may be displayed in the view. It can also contain logic to retrieve the data from some source.
2. Controller: Acts as the connection between view and model. View calls Controller and Controller calls the model. It basically informs the model and/or the view to change as appropriate.
3. View: Deals with UI part. Interacts with the user.

MVVM (Model View View Model)

ViewModel:

1. It is the representation of the state of the view.
2. It holds the data that’s displayed in the view.
3. Responds to view events, aka presentation logic.
4. Calls other functionalities for business logic processing.
5. Never directly asks the view to display anything.

/* 1. Transform your string into lower case
   2. Split your string into an array. Notice the white space I'm using for the separator
   3. Iterate the new array, and assign the current iteration value (array[c]) a new formatted string:
      - With the sentence: array[c][0].toUpperCase() the first letter of the string converts to upper case.
      - With the sentence: array[c].substring(1) we get the rest of the string (from the second letter index to the last one).
      - The "add" (+) character is for concatenate both strings.
   4. return array.join(' ') // Returns the formatted array like a new string. */


function titleCase(str){
    str = str.toLowerCase();
    var array = str.split(' ');
    for(var c = 0; c < array.length; c++){
        array[c] = array[c][0].toUpperCase() + array[c].substring(1);
    }
    return array.join(' ');
}

titleCase("I'm a little tea pot");

Use Set in Python

>>> a = [2,4]
>>> b = [1,4,3]
>>> set(a) - set(b)
set([2])

1. Ascending order

   Reserved.objects.all().filter(client=client_id).order_by('check_in')
   

2. Descending order

   Reserved.objects.all().filter(client=client_id).order_by('-check_in')
   

- (hyphen) is used to indicate descending order here.

After fiddling around a while I found a solution that works in >IE7, Chrome, Firefox:

In General:

An example of an easy way to post XML data and get the response (as a string) would be the following function:

public string postXMLData(string destinationUrl, string requestXml)
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(destinationUrl);
    byte[] bytes;
    bytes = System.Text.Encoding.ASCII.GetBytes(requestXml);
    request.ContentType = "text/xml; encoding='utf-8'";
    request.ContentLength = bytes.Length;
    request.Method = "POST";
    Stream requestStream = request.GetRequestStream();
    requestStream.Write(bytes, 0, bytes.Length);
    requestStream.Close();
    HttpWebResponse response;
    response = (HttpWebResponse)request.GetResponse();
    if (response.StatusCode == HttpStatusCode.OK)
    {
        Stream responseStream = response.GetResponseStream();
        string responseStr = new StreamReader(responseStream).ReadToEnd();
        return responseStr;
    }
    return null;
}

In your specific situation:

Instead of:

request.ContentType = "application/x-www-form-urlencoded";

use:

request.ContentType = "text/xml; encoding='utf-8'";

Also, remove:

string postData = "XMLData=" + Sendingxml;

And replace:

byte[] byteArray = Encoding.UTF8.GetBytes(postData);

with:

byte[] byteArray = Encoding.UTF8.GetBytes(Sendingxml.ToString());

I know the thread is old but i thought someone else might find this useful. According to the jquey.com

var bodyContent = $.ajax({
  url: "script.php",
  global: false,
  type: "POST",
  data: "name=value",
  dataType: "html",
  async:false,
  success: function(msg){
     alert(msg);
  }
}).responseText;

would help to get the result to a string directly. Note the .responseText; part.

Use SelectTab like this:

TabPage t = tabControl1.TabPages[2];
tabControl1.SelectTab(t); //go to tab

Use SelectedTab like this:

TabPage t = tabControl1.TabPages[2];
tabControl1.SelectedTab = t; //go to tab

I struggled understanding how to do this on my first implementation - make sure you have the following:

1) Your device supports vibration (my Samsung tablet did not work so I kept re-checking the code - the original code worked perfectly on my CM Touchpad

2) You have declared above the application level in your AndroidManifest.xml file to give the code permission to run.

3) Have imported both of the following in to your MainActivity.java with the other imports: import android.content.Context; import android.os.Vibrator;

4) Call your vibration (discussed extensively in this thread already) - I did it in a separate function and call this in the code at other points - depending on what you want to use to call the vibration you may need an image (Android: long click on a button -> perform actions) or button listener, or a clickable object as defined in XML (Clickable image - android):

 public void vibrate(int duration)
 {
    Vibrator vibs = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
    vibs.vibrate(duration);    
 }

Another possible root cause is that your tomcat has not completely started yet.

If you do a ps -ef| grep apache, you would see the server running and if you check the catalina.out, it will show that the server initialized in 123ms - but it might still be deploying the applications in your webapps directory.

The answer actually depends on the current list of tracking branches you have. You can fetch a specific branch from remote with git fetch <remote_name> <branch_name> only if the branch is already on the tracking branch list (you can check it with git branch -r).

Let's suppose I have cloned the remote with --single-branch option previously, and in this case the only one tracking branch I have is the "cloned" one. I am a little bit bewildered by advises to tweak git config manually, as well as by typing git remote add <remote_name> <remote_url> commands. As "git remote add" sets up a new remote, it obviously doesn't work with the existing remote repository; supplying "-t branch" options didn't help me.

In case the remote exists, and the branch you want to fetch exists in that remote:

1. Check with git branch -r whether you can see this branch as a tracking branch. If not (as in my case with a single branch clone), add this branch to the tracking branch list by "git remote set-branches" with --add option:

• git remote set-branches --add <remote_name> <branch_name>

2. Fetch the branch you have added from the remote:

• git fetch <remote_name> <branch_name> Note: only after the new tracking branch was fetched from the remote, you can see it in the tracking branch list with git branch -r.

3. Create and checkout a new local branch with "checkout --track", which will be given the same "branch_name" as a tracking branch:

• git checkout --track <remote_name>/<branch_name>

JToken.Type is available after a successful parse. This can be used to eliminate some of the preamble in the answers above and provide insight for finer control of the result. Entirely invalid input (e.g., "{----}".IsValidJson(); will still throw an exception).

    public static bool IsValidJson(this string src)
    {
        try
        {
            var asToken = JToken.Parse(src);
            return asToken.Type == JTokenType.Object || asToken.Type == JTokenType.Array;
        }
        catch (Exception)  // Typically a JsonReaderException exception if you want to specify.
        {
            return false;
        }
    }

When to use dt accessor

A common source of confusion revolves around when to use .year and when to use .dt.year.

The former is an attribute for pd.DatetimeIndex objects; the latter for pd.Series objects. Consider this dataframe:

df = pd.DataFrame({'Dates': pd.to_datetime(['2018-01-01', '2018-10-20', '2018-12-25'])},
                  index=pd.to_datetime(['2000-01-01', '2000-01-02', '2000-01-03']))

The definition of the series and index look similar, but the pd.DataFrame constructor converts them to different types:

type(df.index)     # pandas.tseries.index.DatetimeIndex
type(df['Dates'])  # pandas.core.series.Series

The DatetimeIndex object has a direct year attribute, while the Series object must use the dt accessor. Similarly for month:

df.index.month               # array([1, 1, 1])
df['Dates'].dt.month.values  # array([ 1, 10, 12], dtype=int64)

A subtle but important difference worth noting is that df.index.month gives a NumPy array, while df['Dates'].dt.month gives a Pandas series. Above, we use pd.Series.values to extract the NumPy array representation.

Command-line approach

mkdir android-sdk
cd android-sdk
wget https://dl.google.com/android/repository/sdk-tools-linux-*.zip
unzip sdk-tools-linux-*.zip
tools/bin/sdkmanager --update

When executing the above commands, make sure that you replace * with an appropriate version number which you could find in the download page.

Installing packages

You can also use the sdkmanager to list and to install any specific packages needed.

tools/bin/sdkmanager --list
tools/bin/sdkmanager "platform-tools" "platforms;android–27" "build-tools;27.0.3"

FYI

sdk-tools-linux-*.zip only includes the command-line tools. This extracts content to a single directory named tools, like:

+- android-sdk
    +- tools

To get the SDK packages we could run:

tools/bin/sdkmanager --update

The sdkmanager accepts the following flag:

--sdk_root=<sdkRootPath>: Use the specified SDK root instead of the SDK 
                          containing this tool

But if we omit this flag, it assumes parent directory of tools directory as the sdk root, here in our case android-sdk directory.

If you check the android-sdk folder after running tools/bin/sdkmanager --update it will be like:

+- android-sdk
    +- tools
    +- emulator  
    +- platforms  
    +- platform-tool

If needed, also set ANDROID_HOME environment variable like:

export ANDROID_HOME=/path/to/android-sdk

Email: {
                      group: '.col-sm-3',
                      enabled: false,
                      validators: {
                          //emailAddress: {
                          //    message: 'Email not Valid'
                          //},
                          regexp: {
                              regexp: '^[^@\\s]+@([^@\\s]+\\.)+[^@\\s]+$',
                              message: 'Email not Valid'
                          },
                      }
                  },

As for me, I realized there was another web project in the solution that my VS2017 was loading fine, so I copied over the ProjectTypeGuids element of it over to the project that wasn't loading. Its diff was:

-    <ProjectTypeGuids>{E3E379DF-F4C6-4180-9B81-6769533ABE47};{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>
+    <ProjectTypeGuids>{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>

After this, it loads. Don't ask me why.

JDBC is the predecessor of JPA.

JDBC is a bridge between the Java world and the databases world. In JDBC you need to expose all dirty details needed for CRUD operations, such as table names, column names, while in JPA (which is using JDBC underneath), you also specify those details of database metadata, but with the use of Java annotations.

So JPA creates update queries for you and manages the entities that you looked up or created/updated (it does more as well).

If you want to do JPA without a Java EE container, then Spring and its libraries may be used with the very same Java annotations.

In HTML, SGML and XML, ⁽¹⁾ attributes cannot be repeated, and should only be defined in an element once.

So your example:

<span style="color:blue" style="font-style:italic">Test</span>

is non-conformant to the HTML standard, and will result in undefined behaviour, which explains why different browsers are rendering it differently.

Since there is no defined way to interpret this, browsers can interpret it however they want and merge them, or ignore them as they wish.

^{(1): Every article I can find states that attributes are "key/value" pairs or "attribute-value" pairs, heavily implying the keys must be unique. The best source I can find states:}

^{Attribute names (id and status in this example) are subject to the same restrictions as other names in XML; they need not be unique across the whole DTD, however, but only within the list of attributes for a given element. (Emphasis mine.)}

For strings, you can use string.c_str() which will return you a const char*, which can be treated as an array, example:

const char* strdata = str.c_str();

for (int i = 0; i < str.length(); ++i)
    cout << i << strdata[i];

@Entity is useful with model classes to denote that this is the entity or table

@Table is used to provide any specific name to your table if you want to provide any different name

Note: if you don't use @Table then hibernate consider that @Entity is your table name by default and @Entity must

@Entity    
@Table(name = "emp")     
public class Employee implements java.io.Serializable    
{

}

Use each:

var isValid;
$("input").each(function() {
   var element = $(this);
   if (element.val() == "") {
       isValid = false;
   }
});

However you probably will be better off using something like jQuery validate which IMO is cleaner.

Archive libraries (.a) are statically linked i.e when you compile your program with -c option in gcc. So, if there's any change in library, you need to compile and build your code again.

The advantage of .so (shared object) over .a library is that they are linked during the runtime i.e. after creation of your .o file -o option in gcc. So, if there's any change in .so file, you don't need to recompile your main program. But make sure that your main program is linked to the new .so file with ln command.

This will help you to build the .so files. http://www.yolinux.com/TUTORIALS/LibraryArchives-StaticAndDynamic.html

Hope this helps.

In Android Studio 2.2.3 I think you can change default SDK location for all projects from the top menu:

File -> Project Structure...

A window like below shows up:

Set the main div CSS to somthing like:

<style>
    .wrapper{
        display:flex;
        flex-direction: column;
    }
</style>

<div id="wrapper">
        <div id="inner1">This is inner div 1</div>
        <div id="inner2">This is inner div 2</div>
</div>

When using Python >= 3.6, the cleanest way is to use f-strings with string formatting:

>>> var = 23
>>> f"{var:#010b}"
'0b00010111'

Explanation:

• var the variable to format
• : everything after this is the format specifier
• # use the alternative form (adds the 0b prefix)
• 0 pad with zeros
• 10 pad to a total length off 10 (this includes the 2 chars for 0b)
• b use binary representation for the number

Here is an elegant solution that requires a little work upfront when adding a new project but handles the process very easily.

The idea is that each project links to a Solution file that only contains the assembly version information. So your build process only has to update a single file and all of the assembly versions pull from the one file upon compilation.

Steps:

1. Add a class to you solution file *.cs file, I named min SharedAssemblyProperties.cs
2. Remove all of the cs information from that new file
3. Cut the assembly information from an AssemblyInfo file: [assembly: AssemblyVersion("1.0.0.0")] [assembly: AssemblyFileVersion("1.0.0.0")]
4. Add the statement "using System.Reflection;" to the file and then paste data into your new cs file (ex SharedAssemblyProperties.cs)
5. Add an existing item to you project (wait... read on before adding the file)
6. Select the file and before you click Add, click the dropdown next to the add button and select "Add As Link".
7. Repeat steps 5 and 6 for all existing and new projects in the solution

When you add the file as a link, it stores the data in the project file and upon compilation pulls the assembly version information from this one file.

In you source control, you add a bat file or script file that simply increments the SharedAssemblyProperties.cs file and all of your projects will update their assembly information from that file.

<ListView android:id="@android:id/list"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"/>

this should solve your problem

A better way is to use the Stopwatch class:

using System.Diagnostics;
// ...

Stopwatch sw = new Stopwatch();

sw.Start();

// ...

sw.Stop();

Console.WriteLine("Elapsed={0}",sw.Elapsed);

For windows system you should be able to run php by following below steps:

1. Download php version you want to use and put it in c:\php.
2. append ;c:\php to your system path using cmd or gui.
3. call $ php -S localhost:8000 command in a folder which you want to serve the pages from.

Install Ruby-sass using below command
sudo apt-get -y update
sudo apt-get -y install ruby-full
sudo apt install ruby-sass
gem install bundler

Example
sass SCSS_FILE_PATH:CSS_FILE_PATH;

e.g sass mda/at-md-black.scss:css/at-md-black.css;

On NetBeans : open your project explorer->Dependencies->[file.jar] rightclick->Download Javadoc

If removing the in class doesn't work for you, such was my case, you can force the collapsed initial state using the CSS display property:

...
<div id="collapseOne" class="accordion-body collapse" style="display: none;">
...

You're missing semi-colons after your javascript lines. Also, window.location should have .href or .replace etc to redirect - See this post for more information.

echo '<script type="text/javascript">'; 
echo 'alert("review your answer");'; 
echo 'window.location.href = "index.php";';
echo '</script>';

For clarity, try leaving PHP tags for this:

?>
<script type="text/javascript">
alert("review your answer");
window.location.href = "index.php";
</script>
<?php

NOTE: semi colons on seperate lines are optional, but encouraged - however as in the comments below, PHP won't break lines in the first example here but will in the second, so semi-colons are required in the first example.

If you're using Bootstrap 3, you can use the embed-responsive class and set the padding bottom as the height divided by the width plus a little extra for toolbars. For example, to display an 8.5 by 11 PDF, use 130% (11/8.5) plus a little extra (20%).

<div class='embed-responsive' style='padding-bottom:150%'>
    <object data='URL.pdf' type='application/pdf' width='100%' height='100%'></object>
</div>

Here's the Bootstrap CSS:

.embed-responsive {
    position: relative;
    display: block;
    height: 0;
    padding: 0;
    overflow: hidden;
}

Parse CSV and load as DataFrame/DataSet with Spark 2.x

First, initialize SparkSession object by default it will available in shells as spark

val spark = org.apache.spark.sql.SparkSession.builder
        .master("local") # Change it as per your cluster
        .appName("Spark CSV Reader")
        .getOrCreate;

Use any one of the following ways to load CSV as DataFrame/DataSet

1. Do it in a programmatic way

 val df = spark.read
         .format("csv")
         .option("header", "true") //first line in file has headers
         .option("mode", "DROPMALFORMED")
         .load("hdfs:///csv/file/dir/file.csv")

Update: Adding all options from here in case the link will be broken in future

• path: location of files. Similar to Spark can accept standard Hadoop globbing expressions.
• header: when set to true the first line of files will be used to name columns and will not be included in data. All types will be assumed string. The default value is false.
• delimiter: by default columns are delimited using, but delimiter can be set to any character
• quote: by default the quote character is ", but can be set to any character. Delimiters inside quotes are ignored
• escape: by default, the escape character is , but can be set to any character. Escaped quote characters are ignored
• parserLib: by default, it is "commons" that can be set to "univocity" to use that library for CSV parsing.
• mode: determines the parsing mode. By default it is PERMISSIVE. Possible values are:
  • PERMISSIVE: tries to parse all lines: nulls are inserted for missing tokens and extra tokens are ignored.
  • DROPMALFORMED: drops lines which have fewer or more tokens than expected or tokens which do not match the schema
  • FAILFAST: aborts with a RuntimeException if encounters any malformed line charset: defaults to 'UTF-8' but can be set to other valid charset names
• inferSchema: automatically infers column types. It requires one extra pass over the data and is false by default comment: skip lines beginning with this character. Default is "#". Disable comments by setting this to null.
• nullValue: specifies a string that indicates a null value, any fields matching this string will be set as nulls in the DataFrame
• dateFormat: specifies a string that indicates the date format to use when reading dates or timestamps. Custom date formats follow the formats at java.text.SimpleDateFormat. This applies to both DateType and TimestampType. By default, it is null which means trying to parse times and date by java.sql.Timestamp.valueOf() and java.sql.Date.valueOf().

2. You can do this SQL way as well

 val df = spark.sql("SELECT * FROM csv.`hdfs:///csv/file/dir/file.csv`")

Dependencies:

 "org.apache.spark" % "spark-core_2.11" % 2.0.0,
 "org.apache.spark" % "spark-sql_2.11" % 2.0.0,

Spark version < 2.0

val df = sqlContext.read
    .format("com.databricks.spark.csv")
    .option("header", "true") 
    .option("mode", "DROPMALFORMED")
    .load("csv/file/path"); 

Dependencies:

"org.apache.spark" % "spark-sql_2.10" % 1.6.0,
"com.databricks" % "spark-csv_2.10" % 1.6.0,
"com.univocity" % "univocity-parsers" % LATEST,

you can add this property globally in javascript:

if( navigator.userAgent.match(/iPhone|iPad|iPod/i) ) {
    var styleEl = document.createElement('style'), styleSheet;
    document.head.appendChild(styleEl);
    styleSheet = styleEl.sheet;
    styleSheet.insertRule(".modal { position:absolute; bottom:auto; }", 0);
 }

It's destroy and destroy_all methods, like

user.destroy
User.find(15).destroy
User.destroy(15)
User.where(age: 20).destroy_all
User.destroy_all(age: 20)

Alternatively you can use delete and delete_all which won't enforce :before_destroy and :after_destroy callbacks or any dependent association options.

User.delete_all(condition: 'value') will allow you to delete records without a primary key

Note: from @hammady's comment, user.destroy won't work if User model has no primary key.

Note 2: From @pavel-chuchuva's comment, destroy_all with conditions and delete_all with conditions has been deprecated in Rails 5.1 - see guides.rubyonrails.org/5_1_release_notes.html

Simply do sudo npm cache clean --force --unsafe-perm and npm i will go normally.

You can convert a character from lower case to upper case and vice-versa using bit manipulation as shown below:

#include<stdio.h>
int main(){
  char c;
  printf("Enter a character in uppercase\n");
  scanf("%c",&c);
  c|=' '; // perform or operation on c and ' '
  printf("The lower case of %c is \n",c);
  c&='_'; // perform 'and' operation with '_' to get upper case letter. 
  printf("Back to upper case %c\n",c);   
  return 0;
}

Here's an explanation I wrote recently to help with the void of information on this attribute. http://www.marklio.com/marklio/PermaLink,guid,ecc34c3c-be44-4422-86b7-900900e451f9.aspx (Internet Archive Wayback Machine link)

To quote the most relevant bits:

[Installing .NET] v4 is “non-impactful”. It should not change the behavior of existing components when installed.

The useLegacyV2RuntimeActivationPolicy attribute basically lets you say, “I have some dependencies on the legacy shim APIs. Please make them work the way they used to with respect to the chosen runtime.”

Why don’t we make this the default behavior? You might argue that this behavior is more compatible, and makes porting code from previous versions much easier. If you’ll recall, this can’t be the default behavior because it would make installation of v4 impactful, which can break existing apps installed on your machine.

The full post explains this in more detail. At RTM, the MSDN docs on this should be better.

If jQuery's error handler is being called and the XHR object contains "parser error", that's probably a parser error coming back from the server.

Is your multiple result scenario when you call the service without a parameter, but it's breaking when you try to supply a parameter to retrieve the single record?

What backend are you returning this from?

On ASMX services, for example, that's often the case when parameters are supplied to jQuery as a JSON object instead of a JSON string. If you provide jQuery an actual JSON object for its "data" parameter, it will serialize that into standard & delimited k,v pairs instead of sending it as JSON.

I think your issue is that Range("H18") doesn't contain a formula. Also, you could make your code more efficient by eliminating x. Instead, change your code to

Range("H18").GoalSeek Goal:=Range("H32").Value, ChangingCell:=Range("G18")

Since the old accepted answer got deleted (It was a link to a Google code search results that no longer exist), I figured I could answer this question for future reference :

public static DateTime GetNetworkTime()
{
    //default Windows time server
    const string ntpServer = "time.windows.com";

    // NTP message size - 16 bytes of the digest (RFC 2030)
    var ntpData = new byte[48];

    //Setting the Leap Indicator, Version Number and Mode values
    ntpData[0] = 0x1B; //LI = 0 (no warning), VN = 3 (IPv4 only), Mode = 3 (Client Mode)

    var addresses = Dns.GetHostEntry(ntpServer).AddressList;

    //The UDP port number assigned to NTP is 123
    var ipEndPoint = new IPEndPoint(addresses[0], 123);
    //NTP uses UDP

    using(var socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp))
    {
        socket.Connect(ipEndPoint);

        //Stops code hang if NTP is blocked
        socket.ReceiveTimeout = 3000;     

        socket.Send(ntpData);
        socket.Receive(ntpData);
        socket.Close();
    }

    //Offset to get to the "Transmit Timestamp" field (time at which the reply 
    //departed the server for the client, in 64-bit timestamp format."
    const byte serverReplyTime = 40;

    //Get the seconds part
    ulong intPart = BitConverter.ToUInt32(ntpData, serverReplyTime);

    //Get the seconds fraction
    ulong fractPart = BitConverter.ToUInt32(ntpData, serverReplyTime + 4);

    //Convert From big-endian to little-endian
    intPart = SwapEndianness(intPart);
    fractPart = SwapEndianness(fractPart);

    var milliseconds = (intPart * 1000) + ((fractPart * 1000) / 0x100000000L);

    //**UTC** time
    var networkDateTime = (new DateTime(1900, 1, 1, 0, 0, 0, DateTimeKind.Utc)).AddMilliseconds((long)milliseconds);

    return networkDateTime.ToLocalTime();
}

// stackoverflow.com/a/3294698/162671
static uint SwapEndianness(ulong x)
{
    return (uint) (((x & 0x000000ff) << 24) +
                   ((x & 0x0000ff00) << 8) +
                   ((x & 0x00ff0000) >> 8) +
                   ((x & 0xff000000) >> 24));
}

Note: You will have to add the following namespaces

using System.Net;
using System.Net.Sockets;

It's because you're trying to assign an object by reference. Remove the ampersand and your script should work as intended.

Edit: my bad, you wanted the select to show results after the update, not update from a select.

Have you tried a sub-select?

update mytable set mydate = sysdate 
where mydate in (select mydate from mytable where mydate is null);

You could use negative lookahead, or something like this:

^([^A]|A([^B]|B([^C]|$)|$)|$).*$

Maybe it could be simplified a bit.

VBScript doesn't have Try/Catch. (VBScript language reference. If it had Try, it would be listed in the Statements section.)

On Error Resume Next is the only error handling in VBScript. Sorry. If you want try/catch, JScript is an option. It's supported everywhere that VBScript is and has the same capabilities.

Instead of getting all the table columns using * in your sql statement, you use to specify the table columns you need.

You can use the SQL statement something like:

SELECT CONCAT(FIRSTNAME, ' ', LASTNAME) AS FIRSTNAME FROM customer;

BTW, why couldn't you use FullName instead of FirstName? Like this:

SELECT CONCAT(FIRSTNAME, ' ', LASTNAME) AS 'CUSTOMER NAME' FROM customer;

If you have a numpy array, you can do the following:

>>> import numpy as np
>>> a = np.array([133, 53, 234, 241])
>>> a.astype(np.uint8).data.hex()
'8535eaf1'

If i assume that your second code is the puppet config then i have a logical explaination, if the error and log files were create before, you can try this

sudo chown -R www-data:www-data /var/log/nginx;
sudo chmod -R 755 /var/log/nginx;

Reflection is slower, but works for a situation when you want to know whether that is of type Dog or a Cat and not an instance of Animal. So you'd do something like:

if(null != items.elementAt(1) && items.elementAt(1).getClass().toString().equals("Cat"))
{
//do whatever with cat.. not any other instance of animal.. eg. hideClaws();
}

Not saying the answer above does not work, except the null checking part is necessary.

Another way to answer that is use generics and you are guaranteed to have Double as any element of items.

List<Double> items = new ArrayList<Double>();

Use 'w' and not, 'a'.

if (!$handle = fopen($file, 'w'))

There can be only one ENTRYPOINT, but that target is usually a script that launches as many programs that are needed. You can additionally use for example Supervisord or similar to take care of launching multiple services inside single container. This is an example of a docker container running mysql, apache and wordpress within a single container.

Say, You have one database that is used by a single web application. Then it is probably easier to run both in a single container.

If You have a shared database that is used by more than one application, then it would be better to run the database in its own container and the applications each in their own containers.

There are at least two possibilities how the applications can communicate with each other when they are running in different containers:

1. Use exposed IP ports and connect via them.
2. Recent docker versions support linking.

Probably the easiest solution so far:

public static Bitmap cropCenter(Bitmap bmp) {
    int dimension = Math.min(bmp.getWidth(), bmp.getHeight());
    return ThumbnailUtils.extractThumbnail(bmp, dimension, dimension);
}

imports:

import android.media.ThumbnailUtils;
import java.lang.Math;
import android.graphics.Bitmap;

There are several causes for this error.

MySQL/MariaDB related:

• wait_timeout - Time in seconds that the server waits for a connection to become active before closing it.
• interactive_timeout - Time in seconds that the server waits for an interactive connection.
• max_allowed_packet - Maximum size in bytes of a packet or a generated/intermediate string. Set as large as the largest BLOB, in multiples of 1024.

Example of my.cnf:

[mysqld]
# 8 hours
wait_timeout = 28800
# 8 hours
interactive_timeout = 28800
max_allowed_packet = 256M

Server related:

• Your server has full memory - check info about RAM with free -h

Framework related:

• Check settings of your framework. Django for example use CONN_MAX_AGE (see docs)

How to debug it:

• Check values of MySQL/MariaDB variables.
  • with sql: SHOW VARIABLES LIKE '%time%';
  • command line: mysqladmin variables
• Turn on verbosity for errors:
  • MariaDB: log_warnings = 4
  • MySQL: log_error_verbosity = 3
• Check docs for more info about the error

Check out Marker Clusterer for V3 - this library clusters nearby points into a group marker. The map zooms in when the clusters are clicked. I'd imagine when zoomed right in you'd still have the same problem with markers on the same spot though.

You can also use below just simple to check:

If startDate <> Nothing Then
your logic
End If

It will check that the startDate variable of DateTime datatype is null or not.

Thanks to modern C# 5/6 :)

public void foo()
{
    Task.Delay(1000).ContinueWith(t=> bar());
}

public void bar()
{
    // do stuff
}

You can easily use imcache. A sample code is below.

void example(){
    Cache<Integer,Integer> cache = CacheBuilder.heapCache().
    cacheLoader(new CacheLoader<Integer, Integer>() {
        public Integer load(Integer key) {
            return null;
        }
    }).capacity(10000).build(); 
}

I coudn't get any gain from transactions until I raised cache_size to a higher value i.e. PRAGMA cache_size=10000;

You can't resize the array, per se, but you can create a new array and efficiently copy the elements from the old array to the new array using some utility function like this:

public static int[] removeElement(int[] original, int element){
    int[] n = new int[original.length - 1];
    System.arraycopy(original, 0, n, 0, element );
    System.arraycopy(original, element+1, n, element, original.length - element-1);
    return n;
}

A better approach, however, would be to use an ArrayList (or similar List structure) to store your data and then use its methods to remove elements as needed.

If you want to set to a new color or prevent the change of the color of a specific link after visiting it, add inside the tag of that link:

<a style="text-decoration:none; color:#ff0000;" href="link.html">test link</a>

Above the color is #ff0000 but you can make it anything you'd like.

There may be two causes:

1. It is case-sensitive: DataFrame .... Dataframe, dataframe will not work.

2. You have not install pandas (pip install pandas) in the python path.

This my extension, this is an example of change image with FadIn and FadOut :

fun ImageView.setImageDrawableWithAnimation(@DrawableRes() resId: Int, duration: Long = 300) {    
    if (drawable != null) {
        animate()
            .alpha(0f)
            .setDuration(duration)
             .withEndAction {
                 setImageResource(resId)
                 animate()
                     .alpha(1f)
                     .setDuration(duration)
             }

    } else if (drawable == null) {
        setAlpha(0f)
        setImageResource(resId)
        animate()
            .alpha(1f)
            .setDuration(duration)
    }
}

You can use updateMany() methods of mongodb to update multiple document

Simple query is like this

db.collection.updateMany(filter, update, options)

For more doc of uppdateMany read here

As per your requirement the update code will be like this:

User.updateMany({"created": false}, {"$set":{"created": true}});

here you need to use $set because you just want to change created from true to false. For ref. If you want to change entire doc then you don't need to use $set

You cannot open and read a directory, use the isFile() and isDirectory() methods to distinguish between files and folders. You can get the contents of folders using the list() and listFiles() methods (for filenames and Files respectively) you can also specify a filter that selects a subset of files listed.

you can reverse your array and push the data , at the end again reverse it:

var arr=[2,3,4,5,6];
var arr2=1;
arr.reverse();
//[6,5,4,3,2]
arr.push(arr2);

This is how I solved:

Collections.sort(MyList, (o1, o2) -> o1.getLastModified().compareTo(o2.getLastModified()));

Hope it help you.

What you are looking for is probably this:

ImageView myImageView;
myImageView = mDialog.findViewById(R.id.image_id);
String src = "imageFileName"

int drawableId = this.getResources().getIdentifier(src, "drawable", context.getPackageName())
popupImageView.setImageResource(drawableId);

Let me know if this was helpful :)
