One thing to be mindful of is setting strings then referring back to them. You have to make sure the quotes aren't colliding.

 set start_date = '2019-01-21';
 select ${hiveconf:start_date}; 

When setting dates then referring to them in code as the strings can conflict. This wouldn't work with the start_date set above.

 '${hiveconf:start_date}'

We have to be mindful of not setting twice single or double quotes for strings when referring back to them in the query.

You can simply use % Modulus operator to check divisibility.
For example: n % 2 == 0 means n is exactly divisible by 2 and n % 2 != 0 means n is not exactly divisible by 2.

• from a directory_of_modules, you can import a specific_module.py
• this specific_module.py, can contain a Class with some_methods() or just functions()
• from a specific_module.py, you can instantiate a Class or call functions()
• from this Class, you can execute some_method()

Example:

#!/usr/bin/python3
from directory_of_modules import specific_module
instance = specific_module.DbConnect("username","password")
instance.login()

Excerpts from PEP 8 - Style Guide for Python Code:

Modules should have short and all-lowercase names.

Notice: Underscores can be used in the module name if it improves readability.

A Python module is simply a source file(*.py), which can expose:

• Class: names using the "CapWords" convention.

• Function: names in lowercase, words separated by underscores.

• Global Variables: the conventions are about the same as those for Functions.

Without using third party libraries, calling the same method more than once or creating an array, you can find the maximum of an arbitrary number of doubles like so

public static double max(double... n) {
    int i = 0;
    double max = n[i];

    while (++i < n.length)
        if (n[i] > max)
            max = n[i];

    return max;
}

In your example, max could be used like this

final static int MY_INT1 = 25;
final static int MY_INT2 = -10;
final static double MY_DOUBLE1 = 15.5;

public static void main(String[] args) {
    double maxOfNums = max(MY_INT1, MY_INT2, MY_DOUBLE1);
}

Max heap Usage for the application is is 1024 MB

SPL style:

foreach (new DirectoryIterator(__DIR__) as $file) {
  if ($file->isFile()) {
      print $file->getFilename() . "\n";
  }
}

Check DirectoryIterator and SplFileInfo classes for the list of available methods that you can use.

The question did not state precisely what output is expected but assuming that for month you want the month number (January = 1) and for the year you want the numeric 4 digit year then assuming that we have just run the code in the question:

cycle(date1)
## [1] 3
as.integer(date1)
## [1] 2012

For boot2docker on Windows, after seeing:

FATA[0000] Get http:///var/run/docker.sock/v1.18/version: 
dial unix /var/run/docker.sock: no such file or directory.  
Are you trying to connect to a TLS-enabled daemon without TLS?

All I did was:

boot2docker start
boot2docker shellinit

That generated:

export DOCKER_CERT_PATH=C:\Users\vonc\.boot2docker\certs\boot2docker-vm
export DOCKER_TLS_VERIFY=1
export DOCKER_HOST=tcp://192.168.59.103:2376

Finally:

boot2docker ssh

And docker works again

You want to use the array_key_exists function.

Easiest way is to use --link, however the newer versions of docker are moving away from that and in fact that switch will be removed soon.

The link below offers a nice how too, on connecting two containers. You can skip the attach portion, since that is just a useful how to on adding items to images.

https://deis.com/blog/2016/connecting-docker-containers-1/

The part you are interested in is the communication between two containers. The easiest way, is to refer to the DB container by name from the webserver container.

Example:

you named the db container db1 and the webserver container web0. The containers should both be on the bridge network, which means the web container should be able to connect to the DB container by referring to it's name.

So if you have a web config file for your app, then for DB host you will use the name db1.

if you are using an older version of docker, then you should use --link.

Example:

Step 1: docker run --name db1 oracle/database:12.1.0.2-ee

then when you start the web app. use:

Step 2: docker run --name web0 --link db1 webapp/webapp:3.0

and the web app will be linked to the DB. However, as I said the --link switch will be removed soon.

I'd use docker compose instead, which will build a network for you. However; you will need to download docker compose for your system. https://docs.docker.com/compose/install/#prerequisites

an example setup is like this:

file name is base.yml

version: "2"
services:
  webserver:
    image: "moodlehq/moodle-php-apache:7.1
    depends_on:
      - db
    volumes:
      - "/var/www/html:/var/www/html"
      - "/home/some_user/web/apache2_faildumps.conf:/etc/apache2/conf-enabled/apache2_faildumps.conf"
    environment:
      MOODLE_DOCKER_DBTYPE: pgsql
      MOODLE_DOCKER_DBNAME: moodle
      MOODLE_DOCKER_DBUSER: moodle
      MOODLE_DOCKER_DBPASS: "m@0dl3ing"
      HTTP_PROXY: "${HTTP_PROXY}"
      HTTPS_PROXY: "${HTTPS_PROXY}"
      NO_PROXY: "${NO_PROXY}"
  db:
    image: postgres:9
    environment:
      POSTGRES_USER: moodle
      POSTGRES_PASSWORD: "m@0dl3ing"
      POSTGRES_DB: moodle
      HTTP_PROXY: "${HTTP_PROXY}"
      HTTPS_PROXY: "${HTTPS_PROXY}"
      NO_PROXY: "${NO_PROXY}"

this will name the network a generic name, I can't remember off the top of my head what that name is, unless you use the --name switch.

IE docker-compose --name setup1 up base.yml

NOTE: if you use the --name switch, you will need to use it when ever calling docker compose, so docker-compose --name setup1 down this is so you can have more then one instance of webserver and db, and in this case, so docker compose knows what instance you want to run commands against; and also so you can have more then one running at once. Great for CI/CD, if you are running test in parallel on the same server.

Docker compose also has the same commands as docker so docker-compose --name setup1 exec webserver do_some_command

best part is, if you want to change db's or something like that for unit test you can include an additional .yml file to the up command and it will overwrite any items with similar names, I think of it as a key=>value replacement.

Example:

db.yml

version: "2"
services:
  webserver:
    environment:
      MOODLE_DOCKER_DBTYPE: oci
      MOODLE_DOCKER_DBNAME: XE
  db:
    image: moodlehq/moodle-db-oracle

Then call docker-compose --name setup1 up base.yml db.yml

This will overwrite the db. with a different setup. When needing to connect to these services from each container, you use the name set under service, in this case, webserver and db.

I think this might actually be a more useful setup in your case. Since you can set all the variables you need in the yml files and just run the command for docker compose when you need them started. So a more start it and forget it setup.

NOTE: I did not use the --port command, since exposing the ports is not needed for container->container communication. It is needed only if you want the host to connect to the container, or application from outside of the host. If you expose the port, then the port is open to all communication that the host allows. So exposing web on port 80 is the same as starting a webserver on the physical host and will allow outside connections, if the host allows it. Also, if you are wanting to run more then one web app at once, for whatever reason, then exposing port 80 will prevent you from running additional webapps if you try exposing on that port as well. So, for CI/CD it is best to not expose ports at all, and if using docker compose with the --name switch, all containers will be on their own network so they wont collide. So you will pretty much have a container of containers.

UPDATE: After using features further and seeing how others have done it for CICD programs like Jenkins. Network is also a viable solution.

Example:

docker network create test_network

The above command will create a "test_network" which you can attach other containers too. Which is made easy with the --network switch operator.

Example:

docker run \
    --detach \
    --name db1 \
    --network test_network \
    -e MYSQL_ROOT_PASSWORD="${DBPASS}" \
    -e MYSQL_DATABASE="${DBNAME}" \
    -e MYSQL_USER="${DBUSER}" \
    -e MYSQL_PASSWORD="${DBPASS}" \
    --tmpfs /var/lib/mysql:rw \
    mysql:5

Of course, if you have proxy network settings you should still pass those into the containers using the "-e" or "--env-file" switch statements. So the container can communicate with the internet. Docker says the proxy settings should be absorbed by the container in the newer versions of docker; however, I still pass them in as an act of habit. This is the replacement for the "--link" switch which is going away. Once the containers are attached to the network you created you can still refer to those containers from other containers using the 'name' of the container. Per the example above that would be db1. You just have to make sure all containers are connected to the same network, and you are good to go.

For a detailed example of using network in a cicd pipeline, you can refer to this link: https://git.in.moodle.com/integration/nightlyscripts/blob/master/runner/master/run.sh

Which is the script that is ran in Jenkins for a huge integration tests for Moodle, but the idea/example can be used anywhere. I hope this helps others.

Create a folder named fonts in the assets folder and add the snippet from the below link.

Typeface tf = Typeface.createFromAsset(getApplicationContext().getAssets(),"fonts/fontname.ttf");
textview.setTypeface(tf);

Hello, Swift

Complementing what @Francescu answered.

Adding extra parameters:

func test(function:String -> String, param1:String, param2:String) -> String
{
    return function("test"+param1 + param2)
}

func funcStyle(s:String) -> String
{
    return "FUNC__" + s + "__FUNC"
}
let resultFunc = test(funcStyle, "parameter 1", "parameter 2")

let blockStyle:(String) -> String = {s in return "BLOCK__" + s + "__BLOCK"}
let resultBlock = test(blockStyle, "parameter 1", "parameter 2")

let resultAnon = test({(s:String) -> String in return "ANON_" + s + "__ANON" }, "parameter 1", "parameter 2")


println(resultFunc)
println(resultBlock)
println(resultAnon)

Is synchronous on all cases.

Example of blocking thread with Promises:

  const test = () => new Promise((result, reject) => {
    const time = new Date().getTime() + (3 * 1000);

    console.info('Test start...');

    while (new Date().getTime() < time) {
      // Waiting...
    }

    console.info('Test finish...');
  });

  test()
    .then(() => console.info('Then'))
    .finally(() => console.info('Finally'));

  console.info('Finish!');

The output will be:

Test start...
Test finish...
Finish!

I encountered a similar error. It was a noob mistake done in a hurry. Integer array without declaring size int a[] then trying to access it. C++ compiler should've caught such an error easily if it were in main. However since this particular int array was declared inside an object, it was being created at the same time as my object (many objects were being created) and the compiler was throwing a free(): invalid next size(normal) error. I thought of 2 explanations for this (please enlighten me if anyone knows more): 1.) This resulted in some random memory being assigned to it but since this wasn't accessible it was freeing up all the other heap memory just trying to find this int. 2.) The memory required by it was practically infinite for a program and to assign this it was freeing up all other memory.

A simple:

    int* a;
    class foo{ 
    foo(){
       for(i=0;i<n;i++)
           a=new int[i];
     }

Solved the problem. But it did take a lot of time trying to debug this because the compiler could not "really" find the error.

Self validated model

Your model should implement an interface IValidatableObject. Put your validation code in Validate method:

public class MyModel : IValidatableObject
{
    public string Title { get; set; }
    public string Description { get; set; }

    public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
    {
        if (Title == null)
            yield return new ValidationResult("*", new [] { nameof(Title) });

        if (Description == null)
            yield return new ValidationResult("*", new [] { nameof(Description) });
    }
}

Please notice: this is a server-side validation. It doesn't work on client-side. You validation will be performed only after form submission.

I think I've got it.

Animating to 100% causes it to wrap because the box is bigger than the available width (100% minus the + and the whitespace following it).

Instead, you can animate an inner element, whose 100% is the total width of .contents.

You can solve it in two ways.

1. Make sure you put the CDN into the end of html page and place your own script after that. Example:

    <body>
      <div id="main">
        <div id="mainActivity" v-component="{{currentActivity}}" class="activity"></div>
      </div>
    </body>
    <script src="https://cdn.jsdelivr.net/npm/[email protected]"></script>
    <script src="js/app.js"></script>

where you need to put same javascript code you wrote in any other JavaScript file or in html file.

2. Use window.onload function in your JavaScript file.

I was just going to do this as a comment on the accepted answer but it got too funky (I hate not having line breaks)

ah, so the difference is that in general, Map has certain methods associated with it. but there are different ways or creating a map, such as a HashMap, and these different ways provide unique methods that not all maps have.

Exactly--and you always want to use the most general interface you possibly can. Consider ArrayList vs LinkedList. Huge difference in how you use them, but if you use "List" you can switch between them readily.

In fact, you can replace the right-hand side of the initializer with a more dynamic statement. how about something like this:

List collection;
if(keepSorted)
    collection=new LinkedList();
else
    collection=new ArrayList();

This way if you are going to fill in the collection with an insertion sort, you would use a linked list (an insertion sort into an array list is criminal.) But if you don't need to keep it sorted and are just appending, you use an ArrayList (More efficient for other operations).

This is a pretty big stretch here because collections aren't the best example, but in OO design one of the most important concepts is using the interface facade to access different objects with the exact same code.

Edit responding to comment:

As for your map comment below, Yes using the "Map" interface restricts you to only those methods unless you cast the collection back from Map to HashMap (which COMPLETELY defeats the purpose).

Often what you will do is create an object and fill it in using it's specific type (HashMap), in some kind of "create" or "initialize" method, but that method will return a "Map" that doesn't need to be manipulated as a HashMap any more.

If you ever have to cast by the way, you are probably using the wrong interface or your code isn't structured well enough. Note that it is acceptable to have one section of your code treat it as a "HashMap" while the other treats it as a "Map", but this should flow "down". so that you are never casting.

Also notice the semi-neat aspect of roles indicated by interfaces. A LinkedList makes a good stack or queue, an ArrayList makes a good stack but a horrific queue (again, a remove would cause a shift of the entire list) so LinkedList implements the Queue interface, ArrayList does not.

my trick is to use parseInt(i/chunkSize) and parseInt(i%chunkSize) and then filling the array

// filling items_x000D_
let array = [];_x000D_
for(let i = 0; i< 543; i++)_x000D_
  array.push(i);_x000D_
 _x000D_
 // printing the splitted array_x000D_
 console.log(getSplittedArray(array, 50));_x000D_
 _x000D_
 // get the splitted array_x000D_
 function getSplittedArray(array, chunkSize){_x000D_
  let chunkedArray = [];_x000D_
  for(let i = 0; i<array.length; i++){_x000D_
    try{_x000D_
      chunkedArray[parseInt(i/chunkSize)][parseInt(i%chunkSize)] = array[i];_x000D_
    }catch(e){_x000D_
      chunkedArray[parseInt(i/chunkSize)] = [];_x000D_
      chunkedArray[parseInt(i/chunkSize)][parseInt(i%chunkSize)] = array[i];_x000D_
    }_x000D_

  return chunkedArray;_x000D_

I had a very similar issue to this when testing a restored backup of a mysql and associated php system. No matter what configuration settings I added on mysql it was not making any difference. After troubleshooting the issue for some time I noticed in the mysql logs that the mysql config files were being largely ignored by mysql. The reason was due to the file permissions being too open which was due to the fact my zip backup and restore process was losing all file permissions. I modified my backup and restore scripts to use tar instead and then everything worked as it should.

In summary, check the file permissions on your mysql config files are correct. Hope this helps someone.

Boris Smus's article High DPI Images for Variable Pixel Densities has a more accurate definition of device pixel ratio: the number of device pixels per CSS pixel is a good approximation, but not the whole story.

Note that you can get the DPR used by a device with window.devicePixelRatio.

There's no way you can do that changing only that line. You can do:

a = [1]
b = a
a[0] = 2
b[0]

That creates a list, assigns the reference to a, then b also, uses the a reference to set the first element to 2, then accesses using the b reference variable.

I figured out myself.

cmp calls ComputeBetasAndNuHat which returns a list which has objective as minusloglik

So I can change the function cmp to get this value.

jww is right — you're referencing the wrong intermediate certificate.

As you have been issued with a SHA256 certificate, you will need the SHA256 intermediate. You can grab it from here: http://secure2.alphassl.com/cacert/gsalphasha2g2r1.crt

You can also check the .Any() method:

if (!YourResult.Any())

Just a note that .Any will still retrieve the records from the database; doing a .FirstOrDefault()/.Where() will be just as much overhead but you would then be able to catch the object(s) returned from the query

You need two columns of the same type, one on each table, to JOIN on. Whether they're primary and foreign keys or not doesn't matter.

Update as of npm 5:

As of npm 5.0.0, installed modules are added as a dependency by default, so the --save option is no longer needed. The other save options still exist and are listed in the documentation for npm install.

Original answer:

It won't do anything if you don't have a package.json file. Start by running npm init to create one. Then calls to npm install --save or npm install --save-dev or npm install --save-optional will update the package.json to list your dependencies.

double a = 100.3;
printf("%f %d\n", a, (int)(a* 10.0));

Output Cygwin 100.3 1003
Output MinGW: 100.3 1002

Using (int) to convert double to int seems not to be fail-safe

You can find more about that here: Convert double to int?

In my case, it was an accidental double escaping.

this works:

SelectedPath = @"C:\Program Files\My Company\My product";

this doesn't:

SelectedPath = @"C:\\Program Files\\My Company\\My product";

i=-62 . If you want to convert it to a unsigned representation. It would be 4294967234 for a 32 bit integer. A simple way would be to

num=-62
unsigned int n;
n = num
cout<<n;

4294967234

For the record, here is the class I ended up writing:

I agree with above answer. But here is another way of CSS compression.

You can concat your CSS by using YUI compressor:

module.exports = function(grunt) {
  var exec = require('child_process').exec;
   grunt.registerTask('cssmin', function() {
    var cmd = 'java -jar -Xss2048k '
      + __dirname + '/../yuicompressor-2.4.7.jar --type css '
      + grunt.template.process('/css/style.css') + ' -o '
      + grunt.template.process('/css/style.min.css')
    exec(cmd, function(err, stdout, stderr) {
      if(err) throw err;
    });
  });
}; 

You can't set CURRENT_TIMESTAMP as default value with DATETIME.

But you can do it with TIMESTAMP.

See the difference here.

Words from this blog

The DEFAULT value clause in a data type specification indicates a default value for a column. With one exception, the default value must be a constant; it cannot be a function or an expression.

This means, for example, that you cannot set the default for a date column to be the value of a function such as NOW() or CURRENT_DATE.

The exception is that you can specify CURRENT_TIMESTAMP as the default for a TIMESTAMP column.

check this code:

CREATE TRIGGER trig_Update_Employee ON [EmployeeResult] FOR INSERT AS Begin   
    Insert into Employee (Name, Department)  
    Select Distinct i.Name, i.Department   
        from Inserted i
        Left Join Employee e on i.Name = e.Name and i.Department = e.Department
        where e.Name is null
End

Thanks for the answers. Now I know that there are two ways of "SAVE AS" in Vim.

Assumed that I'm editing hello.txt.

• :w world.txt will write hello.txt's content to the file world.txt while keeping hello.txt as the opened buffer in vim.
• :sav world.txt will first write hello.txt's content to the file world.txt, then close buffer hello.txt, finally open world.txt as the current buffer.

I don't think there is a more "angular way" to select an element. See, for instance, the way they are achieving this goal in the last example of this old documentation page:

{
     template: '<div>' +
    '<div class="title">{{title}}</div>' +
    '<div class="body" ng-transclude></div>' +
    '</div>',

    link: function(scope, element, attrs) {
        // Title element
        var title = angular.element(element.children()[0]),
        // ...
    }
}

I solved a situation where I needed a template for the element that would handle alternatively a regular URL or a javascript call, where the js function needs a reference to the calling element. In javascript, "this" works as a self reference only in the context of a form element, e.g., a button. I didn't want a button, just the apperance of a regular link.

Examples:

<a onclick="http://blahblah" href="http://blahblah" target="_blank">A regular link</a>
<a onclick="javascript:myFunc($(this));return false" href="javascript:myFunc($(this));"  target="_blank">javascript with self reference</a>

The href and onClick attributes have the same values, exept I append "return false" on onClick when it's a javascript call. Having "return false" in the called function did not work.

For some reason, func sizeToFit() does not work for me. My set up is I am using a button inside a UITableViewCell and I am using auto layout.

What worked for me is:

1. get the width constraint
2. get the intrinsicContentSize width because according the this document auto layout is not aware of the intrinsicContentSize. Set the width constraint to the intrinsicContentSize width

Here're two titles from the Debug View Hierachry

Try below code:

public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

        getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));// set transparent in window background

        View _v = inflater.inflate(R.layout.some_you_layout, container, false);

        //load animation
        //Animation transition_in_view = AnimationUtils.loadAnimation(getContext(), android.R.anim.fade_in);// system animation appearance
        Animation transition_in_view = AnimationUtils.loadAnimation(getContext(), R.anim.customer_anim);//customer animation appearance

        _v.setAnimation( transition_in_view );
        _v.startAnimation( transition_in_view );
        //really beautiful
        return _v;

    }

Create the custom Anim.: res/anim/customer_anim.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">

    <translate
        android:duration="500"
        android:fromYDelta="100%"
        android:toYDelta="-7%"/>
    <translate
        android:duration="300"
        android:startOffset="500"
        android:toYDelta="7%" />
    <translate
        android:duration="200"
        android:startOffset="800"
        android:toYDelta="0%" />

</set>

If you're using a webkit browser (and potentially a browser compatible with webkit vendor prefixing), that outline belongs to the button's -webkit-focus-ring pseudoclass. Simply set it's outline to none:

*:-webkit-focus-ring {
  outline: none;
}

Chrome is such a webkit browser, and this effect happens on Linux too (not just a macOS thing, although some Chrome styles are macOS only)

Like others, I had issues with Python 3.5.1/Anaconda 2.4.0 on OS X 10.11..

But I found a compatible package here:

https://anaconda.org/menpo/opencv3

It can be installed via the command line like so:

 conda install -c https://conda.anaconda.org/menpo opencv3

Worked like a charm. First time I've ever gotten OpenCV to work on 3.x!

Pillow is released with installation wheels on Windows:

We provide Pillow binaries for Windows compiled for the matrix of supported Pythons in both 32 and 64-bit versions in wheel, egg, and executable installers. These binaries have all of the optional libraries included

https://pillow.readthedocs.io/en/3.3.x/installation.html#basic-installation

Update: Python 3.6 is now supported by Pillow. Install with pip install pillow and check https://pillow.readthedocs.io/en/latest/installation.html for more information.

However, Python 3.6 is still in alpha and not officially supported yet, although the tests do all pass for the nightly Python builds (currently 3.6a4).

Failing that, downgrade to Python 3.5 or wait until 3.6 is supported by Pillow, probably closer to the 3.6's official release.

UPDATE: From pandas 0.19.2 you can now just pass read_csv() the url directly, although that will fail if it requires authentication.

For older pandas versions, or if you need authentication, or for any other HTTP-fault-tolerant reason:

Use pandas.read_csv with a file-like object as the first argument.

• If you want to read the csv from a string, you can use io.StringIO.

• For the URL https://github.com/cs109/2014_data/blob/master/countries.csv, you get html response, not raw csv; you should use the url given by the Raw link in the github page for getting raw csv response , which is https://raw.githubusercontent.com/cs109/2014_data/master/countries.csv

Example:

import pandas as pd
import io
import requests
url="https://raw.githubusercontent.com/cs109/2014_data/master/countries.csv"
s=requests.get(url).content
c=pd.read_csv(io.StringIO(s.decode('utf-8')))

Notes:

in Python 2.x, the string-buffer object was StringIO.StringIO

In my case, it was because my form was sending to a route with a different middleware. So it blocked from sending information to this specific route.

There is no such thing as an static variable in Javascript. This language is prototype-based object orientated, so there are no classes, but prototypes from where objects "copy" themselves.

You may simulate them with global variables or with prototyping (adding a property to the prototype):

function circle(){
}
circle.prototype.pi=3.14159

Try:

maxInt = -1 >>> 1

In Firefox 3.6 it's 2^31 - 1.

Each instantiation and full specialization of std::atomic<> represents a type that different threads can simultaneously operate on (their instances), without raising undefined behavior:

Objects of atomic types are the only C++ objects that are free from data races; that is, if one thread writes to an atomic object while another thread reads from it, the behavior is well-defined.

In addition, accesses to atomic objects may establish inter-thread synchronization and order non-atomic memory accesses as specified by std::memory_order.

std::atomic<> wraps operations that, in pre-C++ 11 times, had to be performed using (for example) interlocked functions with MSVC or atomic bultins in case of GCC.

Also, std::atomic<> gives you more control by allowing various memory orders that specify synchronization and ordering constraints. If you want to read more about C++ 11 atomics and memory model, these links may be useful:

• C++ atomics and memory ordering
• Comparison: Lockless programming with atomics in C++ 11 vs. mutex and RW-locks
• C++11 introduced a standardized memory model. What does it mean? And how is it going to affect C++ programming?
• Concurrency in C++11

Note that, for typical use cases, you would probably use overloaded arithmetic operators or another set of them:

std::atomic<long> value(0);
value++; //This is an atomic op
value += 5; //And so is this

Because operator syntax does not allow you to specify the memory order, these operations will be performed with std::memory_order_seq_cst, as this is the default order for all atomic operations in C++ 11. It guarantees sequential consistency (total global ordering) between all atomic operations.

In some cases, however, this may not be required (and nothing comes for free), so you may want to use more explicit form:

std::atomic<long> value {0};
value.fetch_add(1, std::memory_order_relaxed); // Atomic, but there are no synchronization or ordering constraints
value.fetch_add(5, std::memory_order_release); // Atomic, performs 'release' operation

Now, your example:

a = a + 12;

will not evaluate to a single atomic op: it will result in a.load() (which is atomic itself), then addition between this value and 12 and a.store() (also atomic) of final result. As I noted earlier, std::memory_order_seq_cst will be used here.

However, if you write a += 12, it will be an atomic operation (as I noted before) and is roughly equivalent to a.fetch_add(12, std::memory_order_seq_cst).

As for your comment:

A regular int has atomic loads and stores. Whats the point of wrapping it with atomic<>?

Your statement is only true for architectures that provide such guarantee of atomicity for stores and/or loads. There are architectures that do not do this. Also, it is usually required that operations must be performed on word-/dword-aligned address to be atomic std::atomic<> is something that is guaranteed to be atomic on every platform, without additional requirements. Moreover, it allows you to write code like this:

void* sharedData = nullptr;
std::atomic<int> ready_flag = 0;

// Thread 1
void produce()
{
    sharedData = generateData();
    ready_flag.store(1, std::memory_order_release);
}

// Thread 2
void consume()
{
    while (ready_flag.load(std::memory_order_acquire) == 0)
    {
        std::this_thread::yield();
    }

    assert(sharedData != nullptr); // will never trigger
    processData(sharedData);
}

Note that assertion condition will always be true (and thus, will never trigger), so you can always be sure that data is ready after while loop exits. That is because:

• store() to the flag is performed after sharedData is set (we assume that generateData() always returns something useful, in particular, never returns NULL) and uses std::memory_order_release order:

memory_order_release

A store operation with this memory order performs the release operation: no reads or writes in the current thread can be reordered after this store. All writes in the current thread are visible in other threads that acquire the same atomic variable

• sharedData is used after while loop exits, and thus after load() from flag will return a non-zero value. load() uses std::memory_order_acquire order:

std::memory_order_acquire

A load operation with this memory order performs the acquire operation on the affected memory location: no reads or writes in the current thread can be reordered before this load. All writes in other threads that release the same atomic variable are visible in the current thread.

This gives you precise control over the synchronization and allows you to explicitly specify how your code may/may not/will/will not behave. This would not be possible if only guarantee was the atomicity itself. Especially when it comes to very interesting sync models like the release-consume ordering.

You would want to use CSS to achieve that.

say you have a table with the attribute id="my_table"

You would want to write the following in your css file

#my_table{
    margin-top:10px //moves your table 10pixels down
    margin-left:10px //moves your table 10pixels right
}

if you do not have a CSS file then you may just add margin-top:10px, margin-left:10px to the style attribute in your table element like so

<table style="margin-top:10px; margin-left:10px;">
    ....
</table>

There are a lot of resources on the net describing CSS and HTML in detail

Using multiple threads on CPython won't give you better performance for pure-Python code due to the global interpreter lock (GIL). I suggest using the multiprocessing module instead:

pool = multiprocessing.Pool(4)
out1, out2, out3 = zip(*pool.map(calc_stuff, range(0, 10 * offset, offset)))

Note that this won't work in the interactive interpreter.

To avoid the usual FUD around the GIL: There wouldn't be any advantage to using threads for this example anyway. You want to use processes here, not threads, because they avoid a whole bunch of problems.

The JTextField offers a getText() and a setText() method - those are for getting and setting the content of the text field.

Use:

<dev class="col-sm-8" style="text-align: center;"><img src="{{URL('image/car-trouble-with-clipping-path.jpg')}}" ></dev>

I think this is the way to center an image in the Laravel framework.

The problem is that you are using the bitwise or operator: |. If you use the logical or operator, ||, your code will work fine.

postgresql.conf is located in PostgreSQL's data directory. The data directory is configured during the setup and the setting is saved as PGDATA entry in c:\Program Files\PostgreSQL\<version>\pg_env.bat, for example

@ECHO OFF
REM The script sets environment variables helpful for PostgreSQL

@SET PATH="C:\Program Files\PostgreSQL\<version>\bin";%PATH%
@SET PGDATA=D:\PostgreSQL\<version>\data
@SET PGDATABASE=postgres
@SET PGUSER=postgres
@SET PGPORT=5432
@SET PGLOCALEDIR=C:\Program Files\PostgreSQL\<version>\share\locale

Alternatively you can query your database with SHOW config_file; if you are a superuser.

I know that this isn't an answer to the initial question ... but you often want to clip the inner content of that rounded corner border you just created.

Chris Cavanagh has come up with an excellent way to do just this.

I have tried a couple different approaches to this ... and I think this one rocks.

Here is the xaml below:

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Background="Black"

    <!-- Rounded yellow border -->
    <Border
        HorizontalAlignment="Center"
        VerticalAlignment="Center"
        BorderBrush="Yellow"
        BorderThickness="3"
        CornerRadius="10"
        Padding="2"
    >
        <Grid>
            <!-- Rounded mask (stretches to fill Grid) -->
            <Border
                Name="mask"
                Background="White"
                CornerRadius="7"
            />

            <!-- Main content container -->
            <StackPanel>
                <!-- Use a VisualBrush of 'mask' as the opacity mask -->
                <StackPanel.OpacityMask>
                    <VisualBrush Visual="{Binding ElementName=mask}"/>
                </StackPanel.OpacityMask>

                <!-- Any content -->

                    Fill="Red"/>
                <Rectangle
                    Height="50"
                    Fill="White"/>
                <Rectangle
                    Height="50"

Run this

$ rbenv init
# Load rbenv automatically by appending
# the following to ~/.zshrc:

eval "$(rbenv init -)"

Follow instructions, (in my case add to ~/.zshrc) ;)

Also important: Changes only take effect if you reboot your console. Two options

• Enter source <modified file>
• close and open again

Event listeners

First off it's important to understand that there are two kinds of "event listeners":

1. Scope event listeners registered via $on:

   $scope.$on('anEvent', function (event, data) {
     ...
   });
   

2. Event handlers attached to elements via for example on or bind:

   element.on('click', function (event) {
     ...
   });
   

$scope.$destroy()

When $scope.$destroy() is executed it will remove all listeners registered via $on on that $scope.

It will not remove DOM elements or any attached event handlers of the second kind.

This means that calling $scope.$destroy() manually from example within a directive's link function will not remove a handler attached via for example element.on, nor the DOM element itself.

element.remove()

Note that remove is a jqLite method (or a jQuery method if jQuery is loaded before AngularjS) and is not available on a standard DOM Element Object.

When element.remove() is executed that element and all of its children will be removed from the DOM together will all event handlers attached via for example element.on.

It will not destroy the $scope associated with the element.

To make it more confusing there is also a jQuery event called $destroy. Sometimes when working with third-party jQuery libraries that remove elements, or if you remove them manually, you might need to perform clean up when that happens:

element.on('$destroy', function () {
  scope.$destroy();
});

What to do when a directive is "destroyed"

This depends on how the directive is "destroyed".

A normal case is that a directive is destroyed because ng-view changes the current view. When this happens the ng-view directive will destroy the associated $scope, sever all the references to its parent scope and call remove() on the element.

This means that if that view contains a directive with this in its link function when it's destroyed by ng-view:

scope.$on('anEvent', function () {
 ...
});

element.on('click', function () {
 ...
});

Both event listeners will be removed automatically.

However, it's important to note that the code inside these listeners can still cause memory leaks, for example if you have achieved the common JS memory leak pattern circular references.

Even in this normal case of a directive getting destroyed due to a view changing there are things you might need to manually clean up.

For example if you have registered a listener on $rootScope:

var unregisterFn = $rootScope.$on('anEvent', function () {});

scope.$on('$destroy', unregisterFn);

This is needed since $rootScope is never destroyed during the lifetime of the application.

The same goes if you are using another pub/sub implementation that doesn't automatically perform the necessary cleanup when the $scope is destroyed, or if your directive passes callbacks to services.

Another situation would be to cancel $interval/$timeout:

var promise = $interval(function () {}, 1000);

scope.$on('$destroy', function () {
  $interval.cancel(promise);
});

If your directive attaches event handlers to elements for example outside the current view, you need to manually clean those up as well:

var windowClick = function () {
   ...
};

angular.element(window).on('click', windowClick);

scope.$on('$destroy', function () {
  angular.element(window).off('click', windowClick);
});

These were some examples of what to do when directives are "destroyed" by Angular, for example by ng-view or ng-if.

If you have custom directives that manage the lifecycle of DOM elements etc. it will of course get more complex.

http://jdpgrailsdev.github.io/blog/2014/09/09/spring_data_hibernate_join.html
from this link:

if you are using JPA on top of Hibernate, there is no way to set the FetchMode used by Hibernate to JOINHowever, if you are using JPA on top of Hibernate, there is no way to set the FetchMode used by Hibernate to JOIN.

The Spring Data JPA library provides a Domain Driven Design Specifications API that allows you to control the behavior of the generated query.

final long userId = 1;

final Specification<User> spec = new Specification<User>() {
   @Override
    public Predicate toPredicate(final Root<User> root, final 
     CriteriaQuery<?> query, final CriteriaBuilder cb) {
    query.distinct(true);
    root.fetch("permissions", JoinType.LEFT);
    return cb.equal(root.get("id"), userId);
 }
};

List<User> users = userRepository.findAll(spec);

If I understand well, you want to Join ScheduleRequest with User and apply the in clause to the userName property of the entity User.

I'd need to work a bit on this schema. But you can try with this trick, that is much more readable than the code you posted, and avoids the Join part (because it handles the Join logic outside the Criteria Query).

List<String> myList = new ArrayList<String> ();
for (User u : usersList) {
    myList.add(u.getUsername());
}
Expression<String> exp = scheduleRequest.get("createdBy");
Predicate predicate = exp.in(myList);
criteria.where(predicate);

In order to write more type-safe code you could also use Metamodel by replacing this line:

Expression<String> exp = scheduleRequest.get("createdBy");

with this:

Expression<String> exp = scheduleRequest.get(ScheduleRequest_.createdBy);

If it works, then you may try to add the Join logic into the Criteria Query. But right now I can't test it, so I prefer to see if somebody else wants to try.

Not a perfect answer though may be code snippets might help.

public <T> List<T> findListWhereInCondition(Class<T> clazz,
            String conditionColumnName, Serializable... conditionColumnValues) {
        QueryBuilder<T> queryBuilder = new QueryBuilder<T>(clazz);
        addWhereInClause(queryBuilder, conditionColumnName,
                conditionColumnValues);
        queryBuilder.select();
        return queryBuilder.getResultList();

    }


private <T> void addWhereInClause(QueryBuilder<T> queryBuilder,
            String conditionColumnName, Serializable... conditionColumnValues) {

        Path<Object> path = queryBuilder.root.get(conditionColumnName);
        In<Object> in = queryBuilder.criteriaBuilder.in(path);
        for (Serializable conditionColumnValue : conditionColumnValues) {
            in.value(conditionColumnValue);
        }
        queryBuilder.criteriaQuery.where(in);

    }

I used this set up in a react app that works. I created a config file named configstrp.js that contains the following:

module.exports = {
ngrok: {
// use the local frontend port to connect
enabled: process.env.NODE_ENV !== 'production',
port: process.env.PORT || 3000,
subdomain: process.env.NGROK_SUBDOMAIN,
authtoken: process.env.NGROK_AUTHTOKEN
},   }

Require the file in the server.

const configstrp      = require('./config/configstrp.js');
const ngrok = configstrp.ngrok.enabled ? require('ngrok') : null;

and connect as such

if (ngrok) {
console.log('If nGronk')
ngrok.connect(
    {
    addr: configstrp.ngrok.port,
    subdomain: configstrp.ngrok.subdomain,
    authtoken: configstrp.ngrok.authtoken,
    host_header:3000
  },
  (err, url) => {
    if (err) {

    } else {

    }
   }
  );
 }

Do not pass a subdomain if you do not have a custom domain

FYI : How to download data in CSV from Kibana:

In Kibana--> 1. Go to 'Discover' in left side

2. Select Index Field (based on your dashboard data) (*** In case if you are not sure which index to select-->go to management tab-->Saved Objects-->Dashboard-->select dashboard name-->scroll down to JSON-->you will see the Index name )

3. left side you see all the variables available in the data-->click over the variable name that you want to have in csv-->click add-->this variable will be added on the right side of the columns avaliable

4. Top right section of the kibana-->there is the time filter-->click -->select the duration for which you want the csv

5. Top upper right -->Reporting-->save this time/variable selection with a new report-->click generate CSV

6. Go to 'Management' in left side--> 'Reporting'-->download your csv

1) place setContentView(R.layout.avtivity_next); to the next-activity's onCreate() method just like this (main) activity's onCreate()

2) if you have not defined the next-activity in your-apps manifest file then do this also, like:

<application
        android:allowBackup="true"
        android:icon="@drawable/app_icon"
        android:label="@string/app_name" >
        <activity
            android:name=".MainActivity"
            android:label="Main Activity" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".NextActivity"
            android:label="Next Activity" >
        </activity>
    </application>

You must have to perform the 2nd step every time you create a new activity, otherwise your app will crash

To keep new lines:

1. First select a character for new line... I used #.
2. Select replace option, extended.
3. input \n replace with #
4. Hit Replace All

Next:

1. Select Replace option Regular Expression.
2. Input this : [^\x20-\x7E]+
3. Keep Replace With Empty
4. Hit Replace All

Now, Select Replace option Extended and Replace # with \n

:) now, you have a clean ASCII file ;)

This will test if strings are made up of some combination or digits, the dollar sign, and a commas. Is that what you're looking for?

import re

s1 = 'Testing string'
s2 = '1234,12345$'

regex = re.compile('[0-9,$]+$')

if ( regex.match(s1) ):
   print "s1 matched"
else:
   print "s1 didn't match"

if ( regex.match(s2) ):
   print "s2 matched"
else:
   print "s2 didn't match"

For the MVC using Model. Model:

public class UserInfo
{
    public string UserID { get; set; }
    public string UserName { get; set; }
    public string Password { get; set; }
    public bool RememberMe { get; set; }
}

HTML:

<input type="checkbox" value="true" id="checkbox1" name="RememberMe" checked="@Model.RememberMe"/>
<label for="checkbox1"></label>

In [HttpPost] function, we can get its properties.

[HttpPost]
public ActionResult Login(UserInfo user)
{
   //...
   return View(user);
}

Any click event before for update /edit/delete records message box alerts the user and if "Ok" proceed for the action else "cancel" remain unchanged. For this code no need to right separate java script code. it works for me

<a asp-action="Delete" asp-route-ID="@Item.ArtistID" onclick = "return confirm('Are you sure you wish to remove this Artist?');">Delete</a>

The -nc, --no-clobber option isn't the best solution as newer files will not be downloaded. One should use -N instead which will download and overwrite the file only if the server has a newer version, so the correct answer is:

wget -N http://www.example.com/images/misc/pic.png

Then running Wget with -N, with or without -r or -p, the decision as to whether or not to download a newer copy of a file depends on the local and remote timestamp and size of the file. -nc may not be specified at the same time as -N.

-N, --timestamping: Turn on time-stamping.

When you really want to write an i-test for a spring data repository you can do it like this:

@RunWith(SpringRunner.class)
@DataJpaTest
@EnableJpaRepositories(basePackageClasses = WebBookingRepository.class)
@EntityScan(basePackageClasses = WebBooking.class)
public class WebBookingRepositoryIntegrationTest {

    @Autowired
    private WebBookingRepository repository;

    @Test
    public void testSaveAndFindAll() {
        WebBooking webBooking = new WebBooking();
        webBooking.setUuid("some uuid");
        webBooking.setItems(Arrays.asList(new WebBookingItem()));
        repository.save(webBooking);

        Iterable<WebBooking> findAll = repository.findAll();

        assertThat(findAll).hasSize(1);
        webBooking.setId(1L);
        assertThat(findAll).containsOnly(webBooking);
    }
}

This worked for me:

export _JAVA_OPTIONS="-Xmx1g"

It's important that you have no spaces because for me it did not work. I would suggest just copying and pasting. Then I ran:

java -XshowSettings:vm

and it will tell you:

Picked up _JAVA_OPTIONS: -Xmx1g

I had the same problem today and figured out that because I typed git submodule init then I had those line in my .git/config:

[submodule]
   active = .

I removed that and typed:

git submodule update --init --remote

And everything was back to normal, my submodule updated in its subdirectory as usual.

$sUrl = 'http://www.linktopage.com/login/';
$params = array('http' => array(
    'method'  => 'POST',
    'content' => 'username=admin195&password=d123456789'
));

$ctx = stream_context_create($params);
$fp = @fopen($sUrl, 'rb', false, $ctx);
if(!$fp) {
    throw new Exception("Problem with $sUrl, $php_errormsg");
}

$response = @stream_get_contents($fp);
if($response === false) {
    throw new Exception("Problem reading data from $sUrl, $php_errormsg");
}

No you can not do that, MyClass *myclass will define a pointer (memory for the pointer is allocated on stack) which is pointing at a random memory location. Trying to use this pointer will cause undefined behavior.

In C++, you can create objects either on stack or heap like this:

MyClass myClass;
myClass.DoSomething();

Above will allocate myClass on stack (the term is not there in the standard I think but I am using for clarity). The memory allocated for the object is automatically released when myClass variable goes out of scope.

Other way of allocating memory is to do a new . In that case, you have to take care of releasing the memory by doing delete yourself.

MyClass* p = new MyClass();
p->DoSomething();
delete p;

Remeber the delete part, else there will be memory leak.

I always prefer to use the stack allocated objects whenever possible as I don't have to be bothered about the memory management.

Try this out: sudo cron reload It works for me on ubuntu 12.10

This answer is specific for WordPress:

$base_dir = trailingslashit( get_stylesheet_directory() );
$base_url = trailingslashit( get_stylesheet_directory_uri() );

$media_dir = $base_dir . 'yourfolder/images/';
$media_url = $hase_url . 'yourfolder/images/';

$image_paths = glob( $media_dir . '*.jpg' );
$image_names = array();
$image_urls = array();

foreach ( $image_paths as $image ) {
    $image_names[] = str_replace( $media_dir, '', $image );
    $image_urls[] = str_replace( $media_dir, $media_url, $image );
}

// --- You now have:

// $image_paths ... list of absolute file paths 
// e.g. /path/to/wordpress/wp-content/uploads/yourfolder/images/sample.jpg

// $image_urls ... list of absolute file URLs 
// e.g. http://example.com/wp-content/uploads/yourfolder/images/sample.jpg

// $image_names ... list of filenames only
// e.g. sample.jpg

Here are some other settings that will give you images from other places than the child theme. Just replace the first 2 lines in above code with the version you need:

From Uploads directory:

// e.g. /path/to/wordpress/wp-content/uploads/yourfolder/images/sample.jpg
$upload_path = wp_upload_dir();
$base_dir = trailingslashit( $upload_path['basedir'] );
$base_url = trailingslashit( $upload_path['baseurl'] );

From Parent-Theme

// e.g. /path/to/wordpress/wp-content/themes/parent-theme/yourfolder/images/sample.jpg
$base_dir = trailingslashit( get_template_directory() );
$base_url = trailingslashit( get_template_directory_uri() );

From Child-Theme

// e.g. /path/to/wordpress/wp-content/themes/child-theme/yourfolder/images/sample.jpg
$base_dir = trailingslashit( get_stylesheet_directory() );
$base_url = trailingslashit( get_stylesheet_directory_uri() );

This can be done very easily using a PostBackUrl and a regular button.

<asp:Button ID="Button1" runat="server" Text="Name of web location" PostBackUrl="web address" />

The problem is the tv.setText(text). The variable tv is probably null and you call the setText method on that null, which you can't. My guess that the problem is on the findViewById method, but it's not here, so I can't tell more, without the code.

It seems you can (somewhat) control the spacing using padding on the <li> tag.

<style type="text/css">
    li { padding-left: 10px; }
</style>

The catch is that it doesn't seem to allow you to scrunch it way-snug like your final example.

For that you could try turning off list-style-type and using &bull;

<ul style="list-style-type: none;">
    <li>&bull;Some list text goes here.</li>
</ul>

You can do the following:

ssh -t xxx.xxx.xxx.xxx "cd /directory_wanted ; bash --login"

This way, you will get a login shell right on the directory_wanted.

Explanation

-t Force pseudo-terminal allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. when implementing menu services.

Multiple -t options force tty allocation, even if ssh has no local tty.

• If you don't use -t then no prompt will appear.
• If you don't add ; bash then the connection will get closed and return control to your local machine
• If you don't add bash --login then it will not use your configs because its not a login shell

I don't know why but animating only the visibility property is not working on any browser.

What you can do is animate the opacity property in such a way that the browser doesn't have enough frames to fade in or out the text.

Example:

span {_x000D_
  opacity: 0;_x000D_
  animation: blinking 1s linear infinite;_x000D_
}_x000D_
_x000D_
@keyframes blinking {_x000D_
  from,_x000D_
  49.9% {_x000D_
    opacity: 0;_x000D_
  }_x000D_
  50%,_x000D_
  to {_x000D_
    opacity: 1;_x000D_
  }_x000D_
}

<span>I'm blinking text</span>

Add the following under @NgModule({})in 'app.module.ts' :

import {CUSTOM_ELEMENTS_SCHEMA} from `@angular/core`;

and then

  imports: [],
  schemas: [ CUSTOM_ELEMENTS_SCHEMA],
  providers: [],

as @fabrizio-valencia said use lower case. in windows if you export mysql database (phpmyadmin) the tables name will converted to lower case and this lead to all sort of problems. see Are table names in MySQL case sensitive?

You have an error in your OrderQuantity column. It is named "OrderQuantity" in the INSERT statement and "OrderQantity" in the table definition.

Also, I don't think you can use NOW() as default value in OrderDate. Try to use the following:

 OrderDate TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP

A couple of reasons I can think of for using an IDE:

• Integrated help is a favorite.
• The built-in Refactor with Preview of the Visual Studio
• IntelliSense, syntax hightlighting, ease of navigation for large projects, integrated debugging, etc. (although I know with addins you can probably get a lot of this with Emacs and Vim).
• Also, I think IDEs these days have a wider user-base, and probably more people developing add-ins for them, but I might be wrong.

And quite frankly, I like my mouse. When I use pure text-based editors it gets lonely.

The permanent space is where the classes, methods, internalized strings, and similar objects used by the VM are stored and never deallocated (hence the name).

This Oracle article succinctly presents the working and parameterization of the HotSpot GC and advises you to augment this space if you load many classes (this is typically the case for application servers and some IDE like Eclipse) :

The permanent generation does not have a noticeable impact on garbage collector performance for most applications. However, some applications dynamically generate and load many classes; for example, some implementations of JavaServer Pages (JSP) pages. These applications may need a larger permanent generation to hold the additional classes. If so, the maximum permanent generation size can be increased with the command-line option -XX:MaxPermSize=.

Note that this other Oracle documentation lists the other HotSpot arguments.

Update : Starting with Java 8, both the permgen space and this setting are gone. The memory model used for loaded classes and methods is different and isn't limited (with default settings). You should not see this error any more.

As of C#6 the best way to get the name of an enum is the new nameof operator:

nameof(MyEnum.EnumValue);

// Ouputs
> "EnumValue"

This works at compile time, with the enum being replaced by the string in the compiled result, which in turn means this is the fastest way possible.

Any use of enum names does interfere with code obfuscation, if you consider obfuscation of enum names to be worthwhile or important - that's probably a whole other question.

try {
        photo.setImageURI(Uri.parse("Location");
        BitmapDrawable drawable = (BitmapDrawable) photo.getDrawable();
        Bitmap bitmap = drawable.getBitmap();
        bitmap = Bitmap.createScaledBitmap(bitmap, 70, 70, true);
        photo.setImageBitmap(bitmap);

    } catch (Exception e) {

    }

I was having a similar issue but none of these fixes worked. The problem was that my button was not yet on the page. The fix for this ended up being going from this:

//Bad code.
var btn = document.createElement('button');
btn.onClick = function() {  console.log("hey");  }

to this:

//Working Code.  I don't like it, but it works. 
var btn = document.createElement('button');
var wrapper = document.createElement('div');
wrapper.appendChild(btn);

document.body.appendChild(wrapper);
var buttons = wrapper.getElementsByTagName("BUTTON");
buttons[0].onclick = function(){  console.log("hey");  }

I have no clue at all why this works. Adding the button to the page and referring to it any other way did not work.

You can use the opt(int) method and use a classical for loop.

provide all custom services means written by you in component decorator section Example : providers: [serviceName]

note:if you are using service for exchanging data between components. declare providers: [serviceName] in module level

You can give it a property display block; so it will behave like a div and have its own line

CSS:

.feature_desc {
   display: block;
   ....
}

If you have more than 2-3 columns, SetOrdinal is not the way to go. A DataView's ToTable method accepts a parameter array of column names. Order your columns there:

DataView dataView = dataTable.DefaultView;
dataTable = dataView.ToTable(true, "Qty", "Unit", "Id");

ISO-8859-1 is a legacy standards from back in 1980s. It can only represent 256 characters so only suitable for some languages in western world. Even for many supported languages, some characters are missing. If you create a text file in this encoding and try copy/paste some Chinese characters, you will see weird results. So in other words, don't use it. Unicode has taken over the world and UTF-8 is pretty much the standards these days unless you have some legacy reasons (like HTTP headers which needs to compatible with everything).

The problem seems to happen when you have an alias the same name as the objects property. Hibernate seems to pick up the alias and use it in the sql. I found this documented here and here, and I believe it to be a bug in Hibernate, although I am not sure that the Hibernate team agrees.

Either way, I have found a simple work around that works in my case. Your mileage may vary. The details are below, I tried to simplify the code for this sample so I apologize for any errors or typo's:

Criteria criteria = session.createCriteria(MyClass.class)
    .setProjection(Projections.projectionList()
        .add(Projections.property("sectionHeader"), "sectionHeader")
        .add(Projections.property("subSectionHeader"), "subSectionHeader")
        .add(Projections.property("sectionNumber"), "sectionNumber"))
    .add(Restrictions.ilike("sectionHeader", sectionHeaderVar)) // <- Problem!
    .setResultTransformer(Transformers.aliasToBean(MyDTO.class));

Would produce this sql:

select
    this_.SECTION_HEADER as y1_,
    this_.SUB_SECTION_HEADER as y2_,
    this_.SECTION_NUMBER as y3_,
from
    MY_TABLE this_ 
where
    ( lower(y1_) like ? ) 

Which was causing an error: java.sql.SQLException: ORA-00904: "Y1_": invalid identifier

But, when I changed my restriction to use "this", like so:

Criteria criteria = session.createCriteria(MyClass.class)
    .setProjection(Projections.projectionList()
        .add(Projections.property("sectionHeader"), "sectionHeader")
        .add(Projections.property("subSectionHeader"), "subSectionHeader")
        .add(Projections.property("sectionNumber"), "sectionNumber"))
    .add(Restrictions.ilike("this.sectionHeader", sectionHeaderVar)) // <- Problem Solved!
    .setResultTransformer(Transformers.aliasToBean(MyDTO.class));

It produced the following sql and my problem was solved.

select
    this_.SECTION_HEADER as y1_,
    this_.SUB_SECTION_HEADER as y2_,
    this_.SECTION_NUMBER as y3_,
from
    MY_TABLE this_ 
where
    ( lower(this_.SECTION_HEADER) like ? ) 

Thats, it! A pretty simple fix to a painful problem. I don't know how this fix would translate to the query by example problem, but it may get you closer.

This is how I organized my application's static resources.

Just for the future reference, you just need to add System.Configuration to your references library:

dummyElem.focus() where dummyElem is a hidden object (e.g. has negative zIndex)?

I use the readonly attribute instead of disabled attribute - as this will still submit the value when the field is readonly.

Note: Any presence of the readonly attribute will make the field readonly even if set to false, so hence why I branch the editor for code like below.

 @if (disabled)
 {
     @Html.EditorFor(model => contact.EmailAddress, new { htmlAttributes = new { @class = "form-control", @readonly = "" } })
 }
 else
 {
     @Html.EditorFor(model => contact.EmailAddress, new { htmlAttributes = new { @class = "form-control" } })
 }

Hope this will help you. Assumed that login form has: username and password inputs.

if(isset($_POST['username']) && trim($_POST['username']) != "" && isset($_POST['password']) && trim($_POST['password']) != ""){
//login
} else {
//register
}

Your where clause will return all rows where tester does not match username AND where tester is not null.

If you want to include NULLs, try:

where tester <> 'username' or tester is null

If you are looking for strings that do not contain the word "username" as a substring, then like can be used:

where tester not like '%username%'

Apache 2 mod_headers

You could also enable Apache 2 mod_headers. On Fedora it's already enabled by default. If you use Ubuntu/Debian, enable it like this:

# First enable headers module for Apache 2,
# and then restart the Apache2 service
a2enmod headers
apache2 -k graceful

On Ubuntu/Debian you can configure headers in the file /etc/apache2/conf-enabled/security.conf

#
# Setting this header will prevent MSIE from interpreting files as something
# else than declared by the content type in the HTTP headers.
# Requires mod_headers to be enabled.
#
#Header set X-Content-Type-Options: "nosniff"

#
# Setting this header will prevent other sites from embedding pages from this
# site as frames. This defends against clickjacking attacks.
# Requires mod_headers to be enabled.
#
Header always set X-Frame-Options: "sameorigin"
Header always set X-Content-Type-Options nosniff
Header always set X-XSS-Protection "1; mode=block"
Header always set X-Permitted-Cross-Domain-Policies "master-only"
Header always set Cache-Control "no-cache, no-store, must-revalidate"
Header always set Pragma "no-cache"
Header always set Expires "-1"
Header always set Content-Security-Policy: "default-src 'none';"
Header always set Content-Security-Policy: "script-src 'self' www.google-analytics.com adserver.example.com www.example.com;"
Header always set Content-Security-Policy: "style-src 'self' www.example.com;"

Note: This is the bottom part of the file. Only the last three entries are CSP settings.

The first parameter is the directive, the second is the sources to be white-listed. I've added Google analytics and an adserver, which you might have. Furthermore, I found that if you have aliases, e.g, www.example.com and example.com configured in Apache 2 you should add them to the white-list as well.

Inline code is considered harmful, and you should avoid it. Copy all the JavaScript code and CSS to separate files and add them to the white-list.

While you're at it you could take a look at the other header settings and install mod_security

The error is completely correct.

As it's trying to tell you, .sort() takes a function that returns number, not boolean.

You need to return negative if the first item is smaller; positive if it it's larger, or zero if they're equal.

I had the same error on git pull origin branchname when setting the remote origin as path fs and not ssh in .git/config:

fatal: '/path/to/repo.git' does not appear to be a git repository 
fatal: The remote end hung up unexpectedly

It was like so (this only works for users on same server of git that have access to git):

url = file:///path/to/repo.git/

Fixed it like so (this works on all users that have access to git user (ssh authorizes_keys or password)):

url = [email protected]:path/to/repo.git

the reason I had it as a directory path was because the git files are on the same server.

In SQL, I would have do it in one shot as

update table1 set col1 = new_value where col1 = old_value

but in Python Pandas, we could just do this:

data = [['ram', 10], ['sam', 15], ['tam', 15]] 
kids = pd.DataFrame(data, columns = ['Name', 'Age']) 
kids

which will generate the following output :

    Name    Age
0   ram     10
1   sam     15
2   tam     15

now we can run:

kids.loc[kids.Age == 15,'Age'] = 17
kids

which will show the following output

Name    Age
0   ram     10
1   sam     17
2   tam     17

which should be equivalent to the following SQL

update kids set age = 17 where age = 15

1. You have to replace \n with <br/> before inset into database.

   $data = str_replace("\n", "<br/>", $data);

   In this case in database table you will see <br/> instead of new line.

   e.g.

   First Line
Second Line

   will look like:

   First Line<br/>Second Line

2. Another way to view data with new line. First read data from database. And then replace \n with <br/> e.g. :

   echo $data;
$data = str_replace("\n", "<br/>", $data);
echo "<br/><br/>" . $data;

   output:

   First Line Second Line

First Line
Second Line

   
   You will find details about function str_replace() here: http://php.net/manual/en/function.str-replace.php

I had the same problem and solved the problem by disabling my firewall(ESET).

The first step to solve this problem should be to try pinging your own computer from another computer. If you have firewall on, you may not be able to ping yourself. I tried pinging my own pc, then ping was failed(didnt get response from the server)

I know this is quite old but if you are looking for the answer to the OP's question on how to return only specified comment, you can use the $ (query) operator like this:

db.question.update({'comments.content': 'xxx'}, {'comments.$': true})

int and double have different semantics. Consider division. 1/2 is 0, 1.0/2.0 is 0.5. In any given situation, one of those answers will be right and the other wrong.

That said, there are programming languages, such as JavaScript, in which 64-bit float is the only numeric data type. You have to explicitly truncate some division results to get the same semantics as Java int. Languages such as Java that support integer types make truncation automatic for integer variables.

In addition to having different semantics from double, int arithmetic is generally faster, and the smaller size (32 bits vs. 64 bits) leads to more efficient use of caches and data transfer bandwidth.

Does GitHub have this social feature?

If the commit email is kept private, GitHub now (July 2020) proposes:

Users and organizations can now add Twitter usernames to their GitHub profiles

You can now add your Twitter username to your GitHub profile directly from your profile page, via profile settings, and also the REST API.

We've also added the latest changes:

• Organization admins can now add Twitter usernames to their profile via organization profile settings and the REST API.
• All users are now able to see Twitter usernames on user and organization profiles, as well as via the REST and GraphQL APIs.
• When sponsorable maintainers and organizations add Twitter usernames to their profiles, we'll encourage new sponsors to include that Twitter username when they share their sponsorships on Twitter.

That could be a workaround to leave a message to a GitHub user.

This happens to me when the branch I'm working in gets deleted from the repository, but the workspace I'm in is not updated. (We have a tool that lets you create multiple git "workspaces" from the same repository using simlinks.)

If git branch does not mark any branch as current, try doing

git reset --hard <<some branch>>

I tried a number of approaches until I worked this one out.

If elements are always nearly sorted as in your example then builtin .sort() (timsort) should be fast:

>>> a = [1,1,2]
>>> b = [1,2,2]
>>> a.sort()
>>> b.sort()
>>> a == b
False

If you don't want to sort inplace you could use sorted().

In practice it might always be faster then collections.Counter() (despite asymptotically O(n) time being better then O(n*log(n)) for .sort()). Measure it; If it is important.

I know it is an old topic, but If your SQL server version is higher than 2012.

There is another simple option can choose, FORMAT function.

SELECT FORMAT(GetDate(),'yyyyMM')

Short answer: it's closely related to the Content-Security-Policy: upgrade-insecure-requests response header, indicating that the browser supports it (and in fact prefers it).

It took me 30mins of Googling, but I finally found it buried in the W3 spec.

The confusion comes because the header in the spec was HTTPS: 1, and this is how Chromium implemented it, but after this broke lots of websites that were poorly coded (particularly WordPress and WooCommerce) the Chromium team apologized:

"I apologize for the breakage; I apparently underestimated the impact based on the feedback during dev and beta."
— Mike West, in Chrome Issue 501842

Their fix was to rename it to Upgrade-Insecure-Requests: 1, and the spec has since been updated to match.

Anyway, here is the explanation from the W3 spec (as it appeared at the time)...

The HTTPS HTTP request header field sends a signal to the server expressing the client’s preference for an encrypted and authenticated response, and that it can successfully handle the upgrade-insecure-requests directive in order to make that preference as seamless as possible to provide.

...

When a server encounters this preference in an HTTP request’s headers, it SHOULD redirect the user to a potentially secure representation of the resource being requested.

When a server encounters this preference in an HTTPS request’s headers, it SHOULD include a Strict-Transport-Security header in the response if the request’s host is HSTS-safe or conditionally HSTS-safe [RFC6797].

As far as i know this seems out of scope of an IDE. Copyin ,you can copy the string and then try to format it using ctrl+shift+ F Most often these multiline strings are not used hard coded,rather they shall be used from property or xml files.which can be edited at later point of time without the need for code change

Following is the format of the crontab file.

{minute} {hour} {day-of-month} {month} {day-of-week} {user} {path-to-shell-script}

text= re.sub('[0-9\n]',' ',text)

install regex in python which is re then do the following code.

For the current information you are giving, it will be enought with this simple regex to do the replacement:

str.replaceAll(",", ".");

A certain type of rounding is also implemented in Boost:

#include <iostream>

#include <boost/numeric/conversion/converter.hpp>

template<typename T, typename S> T round2(const S& x) {
  typedef boost::numeric::conversion_traits<T, S> Traits;
  typedef boost::numeric::def_overflow_handler OverflowHandler;
  typedef boost::numeric::RoundEven<typename Traits::source_type> Rounder;
  typedef boost::numeric::converter<T, S, Traits, OverflowHandler, Rounder> Converter;
  return Converter::convert(x);
}

int main() {
  std::cout << round2<int, double>(0.1) << ' ' << round2<int, double>(-0.1) << ' ' << round2<int, double>(-0.9) << std::endl;
}

Note that this works only if you do a to-integer conversion.

Following on from brillout.com's answer, and also Roman Nurik's answer, and relaxing somewhat the the 'no SVG' requirement, you can desaturate images in Firefox using only a single SVG file and some CSS.

Your SVG file will look like this:

<?xml version="1.0" encoding="UTF-8"?>
<svg version="1.1"
     baseProfile="full"
     xmlns="http://www.w3.org/2000/svg">
    <filter id="desaturate">
        <feColorMatrix type="matrix" values="0.3333 0.3333 0.3333 0 0
                                             0.3333 0.3333 0.3333 0 0
                                             0.3333 0.3333 0.3333 0 0
                                             0      0      0      1 0"/>
    </filter>
</svg>

Save that as resources.svg, it can be reused from now on for any image you want to change to greyscale.

In your CSS you reference the filter using the Firefox specific filter property:

.target {
    filter: url(resources.svg#desaturate);
}

Add the MS proprietary ones too if you feel like it, apply that class to any image you want to convert to greyscale (works in Firefox >3.5, IE8).

edit: Here's a nice blog post which describes using the new CSS3 filter property in SalmanPK's answer in concert with the SVG approach described here. Using that approach you'd end up with something like:

img.desaturate{
    filter: gray; /* IE */
    -webkit-filter: grayscale(1); /* Old WebKit */
    -webkit-filter: grayscale(100%); /* New WebKit */
    filter: url(resources.svg#desaturate); /* older Firefox */
    filter: grayscale(100%); /* Current draft standard */
}

This is a good and a tricky question. The topic of URI design is at the same time the most prominent part of a REST API and, therefore, a potentially long-term commitment towards the users of that API.

Since evolution of an application and, to a lesser extent, its API is a fact of life and that it's even similar to the evolution of a seemingly complex product like a programming language, the URI design should have less natural constraints and it should be preserved over time. The longer the application's and API's lifespan, the greater the commitment to the users of the application and API.

On the other hand, another fact of life is that it is hard to foresee all the resources and their aspects that would be consumed through the API. Luckily, it is not necessary to design the entire API which will be used until Apocalypse. It is sufficient to correctly define all the resource end-points and the addressing scheme of every resource and resource instance.

Over time you may need to add new resources and new attributes to each particular resource, but the method that API users follow to access a particular resources should not change once a resource addressing scheme becomes public and therefore final.

This method applies to HTTP verb semantics (e.g. PUT should always update/replace) and HTTP status codes that are supported in earlier API versions (they should continue to work so that API clients that have worked without human intervention should be able to continue to work like that).

Furthermore, since embedding of API version into the URI would disrupt the concept of hypermedia as the engine of application state (stated in Roy T. Fieldings PhD dissertation) by having a resource address/URI that would change over time, I would conclude that API versions should not be kept in resource URIs for a long time meaning that resource URIs that API users can depend on should be permalinks.

Sure, it is possible to embed API version in base URI but only for reasonable and restricted uses like debugging a API client that works with the the new API version. Such versioned APIs should be time-limited and available to limited groups of API users (like during closed betas) only. Otherwise, you commit yourself where you shouldn't.

A couple of thoughts regarding maintenance of API versions that have expiration date on them. All programming platforms/languages commonly used to implement web services (Java, .NET, PHP, Perl, Rails, etc.) allow easy binding of web service end-point(s) to a base URI. This way it's easy to gather and keep a collection of files/classes/methods separate across different API versions.

From the API users POV, it's also easier to work with and bind to a particular API version when it's this obvious but only for limited time, i.e. during development.

From the API maintainer's POV, it's easier to maintain different API versions in parallel by using source control systems that predominantly work on files as the smallest unit of (source code) versioning.

However, with API versions clearly visible in URI there's a caveat: one might also object this approach since API history becomes visible/aparent in the URI design and therefore is prone to changes over time which goes against the guidelines of REST. I agree!

The way to go around this reasonable objection, is to implement the latest API version under versionless API base URI. In this case, API client developers can choose to either:

• develop against the latest one (committing themselves to maintain the application protecting it from eventual API changes that might break their badly designed API client).

• bind to a specific version of the API (which becomes apparent) but only for a limited time

For example, if API v3.0 is the latest API version, the following two should be aliases (i.e. behave identically to all API requests):

http://shonzilla/api/customers/1234
http://shonzilla/api/v3.0/customers/1234
http://shonzilla/api/v3/customers/1234

In addition, API clients that still try to point to the old API should be informed to use the latest previous API version, if the API version they're using is obsolete or not supported anymore. So accessing any of the obsolete URIs like these:

http://shonzilla/api/v2.2/customers/1234
http://shonzilla/api/v2.0/customers/1234
http://shonzilla/api/v2/customers/1234
http://shonzilla/api/v1.1/customers/1234
http://shonzilla/api/v1/customers/1234

should return any of the 30x HTTP status codes that indicate redirection that are used in conjunction with Location HTTP header that redirects to the appropriate version of resource URI which remain to be this one:

http://shonzilla/api/customers/1234

There are at least two redirection HTTP status codes that are appropriate for API versioning scenarios:

• 301 Moved permanently indicating that the resource with a requested URI is moved permanently to another URI (which should be a resource instance permalink that does not contain API version info). This status code can be used to indicate an obsolete/unsupported API version, informing API client that a versioned resource URI been replaced by a resource permalink.

• 302 Found indicating that the requested resource temporarily is located at another location, while requested URI may still supported. This status code may be useful when the version-less URIs are temporarily unavailable and that a request should be repeated using the redirection address (e.g. pointing to the URI with APi version embedded) and we want to tell clients to keep using it (i.e. the permalinks).

• other scenarios can be found in Redirection 3xx chapter of HTTP 1.1 specification

You can use addBatch and executeBatch for batch insert in java See the Example : Batch Insert In Java

Learn to use else.

Since value will never be equal to two unequal strings at once, there are only 5 possible outcomes -- one for each value you care about, plus one for "none of the above". But because your code doesn't eliminate the tests that can't pass, it has 16 "possible" paths (2 ^ the number of tests), of which most will never be followed.

With else, the only paths that exist are the 5 that can actually happen.

String value = some methodx;
if ("apple".equals(value )) {
    method1;
}
else if ("carrot".equals(value )) {
    method2;
}
else if ("mango".equals(value )) {
    method3;
}
else if ("orance".equals(value )) {
    method4;
}

Or start using JDK 7, which includes the ability to use strings in a switch statement. Course, Java will just compile the switch into an if/else like construct anyway...

You can use https://github.com/keighl/KTCenterFlowLayout like this:

I use zsh and Android Studio. I use a variable for my Android SDK path and configure in the file ~/.zshrc:

export ANDROID_HOME=/Applications/Android\ Studio.app/sdk
export PATH="$ANDROID_HOME/platform-tools:$ANDROID_HOME/tools:$PATH"

Note: Make sure not to include single or double quotes around the specified path. If you do, it won't work.

Looks like this exception message is quite generic and can be received due to a variety of reasons. We ran into this while deploying the client on Windows 8.1 machines. Our WCF client runs inside of a windows service and continuously polls the WCF service. The windows service runs under a non-admin user. The issue was fixed by setting the clientCredentialType to "Windows" in the WCF configuration to allow the authentication to pass-through, as in the following:

      <security mode="None">
        <transport clientCredentialType="Windows" proxyCredentialType="None"
          realm="" />
        <message clientCredentialType="UserName" algorithmSuite="Default" />
      </security>

I've recently implemented the canonical map-reduce example in Akka: Word count. So it's one use case of Akka: better performance. It was more of a experiment of JRuby and Akka's actors than anything else, but it also shows that Akka is not Scala or Java only: it works on all languages on top of JVM.

TYPE variable = jsonbody["key"]?.Value<TYPE>() ?? DEFAULT_VALUE;

e.g.

bool attachMap = jsonbody["map"]?.Value<bool>() ?? false;

Using jQuery:

get_between <- function(str, first_character, last_character) {
    new_str = str.match(first_character + "(.*)" + last_character)[1].trim()
    return(new_str)
    }

string

my_string = 'and the thing that ! on the @ with the ^^ goes now' 

usage:

get_between(my_string, 'that', 'now')

result:

"! on the @ with the ^^ goes

See ReceivedTime Property

http://msdn.microsoft.com/en-us/library/office/aa171873(v=office.11).aspx

You added another \ to the end of C:\Temp\ in the SaveAs File line. Could be a problem. Do a test first before adding a path separator.

dateFormat = Format(itm.ReceivedTime, "yyyy-mm-dd H-mm")  
saveFolder = "C:\Temp"

You have not set objAtt so there is no need for "Set objAtt = Nothing". If there was it would be just before End Sub not in the loop.

Public Sub saveAttachtoDisk (itm As Outlook.MailItem) 
    Dim objAtt As Outlook.Attachment 
    Dim saveFolder As String Dim dateFormat
    dateFormat = Format(itm.ReceivedTime, "yyyy-mm-dd H-mm")  saveFolder = "C:\Temp"
    For Each objAtt In itm.Attachments
        objAtt.SaveAsFile saveFolder & "\" & dateFormat & objAtt.DisplayName
    Next
End Sub

Re: It worked the first day I started tinkering but after that it stopped saving files.

This is usually due to Security settings. It is a "trap" set for first time users to allow macros then take it away. http://www.slipstick.com/outlook-developer/how-to-use-outlooks-vba-editor/

A solid and easy way to handle it in single threaded code would be to catch it and retrow it in a RuntimeException, to avoid the need to declare it for every method.

Alternatively, using the package Deducer

library(Deducer)
dd<- sortData(dd,c("z","b"),increasing= c(FALSE,TRUE))

Most of above answer are right, so written a helper methods, so you can use it directly in you project .

set layout_gravity programmtically

// gravity types : Gravity.BOTTOM, Gravity.START etc.
// view : can be any view example : button, textview, linearlayout, image etc.

// for single view
   public static void setLayoutGravity(int gravity, View view){
     ((LinearLayout.LayoutParams) view.getLayoutParams()).gravity = gravity;
    }


// for mulitple views
  public static void setLayoutGravity(int gravity, View ...view){
        for(View item : view)
            ((LinearLayout.LayoutParams) item.getLayoutParams()).gravity = gravity;
    }

Since Spring 5 you just need to implement the interface WebMvcConfigurer:

public class MvcConfig implements WebMvcConfigurer {

This is because Java 8 introduced default methods on interfaces which cover the functionality of the WebMvcConfigurerAdapter class

See here:

https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/servlet/config/annotation/WebMvcConfigurerAdapter.html

The bigest collection (today 1313) of decent and weird programming languages I know, you will find here: http://99-bottles-of-beer.net/ be prepared to see real weird stuff ;-) Everybody should make his one choice

If your project has a CMake configuration it's pretty straight forward to setup VSCode, e.g. setup tasks.json like below:

{
    "version": "0.1.0",
    "command": "sh",
    "isShellCommand": true,
    "args": ["-c"],
    "showOutput": "always",
    "suppressTaskName": true,
    "options": {
        "cwd": "${workspaceRoot}/build"
    },
    "tasks": [
        {
            "taskName": "cmake",
            "args": ["cmake ."]
        },
        {
            "taskName": "make",
            "args" : ["make"],
            "isBuildCommand": true,
            "problemMatcher": {
                "owner": "cpp",
                "fileLocation": "absolute",
                "pattern": {
                    "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
                    "file": 1,
                    "line": 2,
                    "column": 3,
                    "severity": 4,
                    "message": 5
                }
            }
        }
    ]
}

This assumes that there is a folder build in the root of the workspace with a CMake configuration.

There's also a CMake integration extension that adds a "CMake build" command to VScode.

PS! The problemMatcher is setup for clang-builds. To use GCC I believe you need to change fileLocation to relative, but I haven't tested this.

To kill a process by a specific keyword you could create an alias in ~/.bashrc (linux) or ~/.bash_profile (mac).

alias killps="kill -9 `ps -ef | grep '[k]eyword' | awk '{print $2}'`"

(
SELECT yr as YEAR, COUNT(title) as TCOUNT

GROUP BY yr
order by TCOUNT desc
) res

If anybody needs a simple thing, following is a simple key-expiring set. It might be converted to a map easily.

public class CacheSet<K> {
    public static final int TIME_OUT = 86400 * 1000;

    LinkedHashMap<K, Hit> linkedHashMap = new LinkedHashMap<K, Hit>() {
        @Override
        protected boolean removeEldestEntry(Map.Entry<K, Hit> eldest) {
            final long time = System.currentTimeMillis();
            if( time - eldest.getValue().time > TIME_OUT) {
                Iterator<Hit> i = values().iterator();

                i.next();
                do {
                    i.remove();
                } while( i.hasNext() && time - i.next().time > TIME_OUT );
            }
            return false;
        }
    };


    public boolean putIfNotExists(K key) {
        Hit value = linkedHashMap.get(key);
        if( value != null ) {
            return false;
        }

        linkedHashMap.put(key, new Hit());
        return true;
    }

    private static class Hit {
        final long time;


        Hit() {
            this.time = System.currentTimeMillis();
        }
    }
}

Just how you've done it. assertTrue(boolean) also has an overload assertTrue(String, boolean) where the String is the message in case of failure; you can use that if you want to print that such-and-such wasn't greater than so-and-so.

You could also add hamcrest-all as a dependency to use matchers. See https://code.google.com/p/hamcrest/wiki/Tutorial:

import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.Matchers.*;

assertThat("timestamp",
           Long.parseLong(previousTokenValues[1]),
           greaterThan(Long.parseLong(currentTokenValues[1])));

That gives an error like:

java.lang.AssertionError: timestamp
Expected: a value greater than <456L>
     but: <123L> was less than <456L>

Take a look at cavaj.

Sorry, now I've read what you expected better, so I'm updating the answer.

Based on the HTML5 Specs from W3C, nothing is wrong. I created this JSFiddle test and it's behaving correctly based on the specs (for those browsers based on the specs, like Chrome 11 and Firefox 4):

<form>_x000D_
    <input type="checkbox" name="q" id="a-0" required autofocus>_x000D_
    <label for="a-0">a-1</label>_x000D_
    <br>_x000D_
_x000D_
    <input type="checkbox" name="q" id="a-1" required>_x000D_
    <label for="a-1">a-2</label>_x000D_
    <br>_x000D_
_x000D_
    <input type="checkbox" name="q" id="a-2" required>_x000D_
    <label for="a-2">a-3</label>_x000D_
    <br>_x000D_
_x000D_
    <input type="submit">_x000D_
</form>

I agree that it isn't very usable (in fact many people have complained about it in the W3C's mailing lists).

But browsers are just following the standard's recommendations, which is correct. The standard is a little misleading, but we can't do anything about it in practice. You can always use JavaScript for form validation, though, like some great jQuery validation plugin.

Another approach would be choosing a polyfill that can make (almost) all browsers interpret form validation rightly.

I would do the following

1. Create (convert SP to) a UDF (Table value UDF).

2. select * into #tmpBusLine from dbo.UDF_getBusinessLineHistory '16 Mar 2009'

For django 1.9+
You can use Fields disabled argument to make field disable. e.g. In following code snippet from forms.py file , I have made employee_code field disabled

class EmployeeForm(forms.ModelForm):
    employee_code = forms.CharField(disabled=True)
    class Meta:
        model = Employee
        fields = ('employee_code', 'designation', 'salary')

Reference https://docs.djangoproject.com/en/dev/ref/forms/fields/#disabled

I found a short solution for it. No extra code is needed just trigger the changeDate event. E.g. $('.datepicker').datepicker().trigger('changeDate');

Try only using -e (--execute) option:

$ mysql -u root -proot -e "SHOW GLOBAL VARIABLES LIKE 'PORT';"                                                                                                       (8s 26ms)
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| port          | 3306  |
+---------------+-------+

Replace root by your "username" and "password"

I suggest following workaround for "Henrik Paul"'s workaround/idea :)

You know names of private methods of your class. For example they are like _add(), _edit(), _delete() etc.

Hence when you want to test it from aspect of unit-testing, just call private methods by prefixing and/or suffixing some common word (for example _addPhpunit) so that when __call() method is called (since method _addPhpunit() doesn't exist) of owner class, you just put necessary code in __call() method to remove prefixed/suffixed word/s (Phpunit) and then to call that deduced private method from there. This is another good use of magic methods.

Try it out.

Probably AES. Blowfish was the direct predecessor to Twofish. Twofish was Bruce Schneier's entry into the competition that produced AES. It was judged as inferior to an entry named Rijndael, which was what became AES.

Interesting aside: at one point in the competition, all the entrants were asked to give their opinion of how the ciphers ranked. It's probably no surprise that each team picked its own entry as the best -- but every other team picked Rijndael as the second best.

That said, there are some basic differences in the basic goals of Blowfish vs. AES that can (arguably) favor Blowfish in terms of absolute security. In particular, Blowfish attempts to make a brute-force (key-exhaustion) attack difficult by making the initial key setup a fairly slow operation. For a normal user, this is of little consequence (it's still less than a millisecond) but if you're trying out millions of keys per second to break it, the difference is quite substantial.

In the end, I don't see that as a major advantage, however. I'd generally recommend AES. My next choices would probably be Serpent, MARS and Twofish in that order. Blowfish would come somewhere after those (though there are a couple of others that I'd probably recommend ahead of Blowfish).

It is possible to write to an excel file without opening it using the Microsoft.Jet.OLEDB.4.0 and OleDb. Using OleDb, it behaves as if you were writing to a table using sql.

Here is the code I used to create and write to an new excel file. No extra references are needed

var connectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\SomePath\ExcelWorkBook.xls;Extended Properties=Excel 8.0";
using (var excelConnection = new OleDbConnection(connectionString))
{
    // The excel file does not need to exist, opening the connection will create the
    // excel file for you
    if (excelConnection.State != ConnectionState.Open) { excelConnection.Open(); }

    // data is an object so it works with DBNull.Value
    object propertyOneValue = "cool!";
    object propertyTwoValue = "testing";

    var sqlText = "CREATE TABLE YourTableNameHere ([PropertyOne] VARCHAR(100), [PropertyTwo] INT)";

    // Executing this command will create the worksheet inside of the workbook
    // the table name will be the new worksheet name
    using (var command = new OleDbCommand(sqlText, excelConnection)) { command.ExecuteNonQuery(); }

    // Add (insert) data to the worksheet
    var commandText = $"Insert Into YourTableNameHere ([PropertyOne], [PropertyTwo]) Values (@PropertyOne, @PropertyTwo)";

    using (var command = new OleDbCommand(commandText, excelConnection))
    {
        // We need to allow for nulls just like we would with
        // sql, if your data is null a DBNull.Value should be used
        // instead of null 
        command.Parameters.AddWithValue("@PropertyOne", propertyOneValue ?? DBNull.Value);
        command.Parameters.AddWithValue("@PropertyTwo", propertyTwoValue ?? DBNull.Value);

        command.ExecuteNonQuery();
    }
}

Interesting I never spent too much time adjusting the colours in IntelliJ although tried once.

See link below with an already defined colour scheme you can import.

Where can I download IntelliJ IDEA 10 Color Schemes?

http://devnet.jetbrains.net/docs/DOC-1154

Download the jar file, file import the jar where you will see a what to import ;)

"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, "");

Delta list/delta queue are used in programs like cron or event simulators to work out when the next event should fire. http://everything2.com/title/delta+list http://www.cs.iastate.edu/~cs554/lec_notes/delta_clock.pdf

you can simply disable maximize inside form constructor.

 public Form1(){
     InitializeComponent();
     MaximizeBox = false;
 }

to minimize when closing.

private void Form1_FormClosing(Object sender, FormClosingEventArgs e) {
    e.Cancel = true;
    WindowState = FormWindowState.Minimized;
}

Use the date() method:

datetime.datetime.now().date()

There are several ways to try to prevent line breaks, and the phrase “a newer construct” might refer to more than one way—that’s actually the most reasonable interpretation. They probably mostly think of the CSS declaration white-space:nowrap and possibly the no-break space character. The different ways are not equivalent, far from that, both in theory and especially in practice, though in some given case, different ways might produce the same result.

There is probably nothing real to be gained by switching from the HTML attribute to the somewhat clumsier CSS way, and you would surely lose when style sheets are disabled. But even the nowrap attribute does no work in all situations. In general, what works most widely is the nobr markup, which has never made its way to any specifications but is alive and kicking: <td><nobr>...</nobr></td>.

For completeness here is the HTML Helper for DropDownListFor that adds enabled parameter, when false select is disabled. It keeps html attributes defined in markup, or it enables usage of html attributes in markup, it posts select value to server and usage is very clean and simple.

Here is the code for helper:

public static MvcHtmlString DropDownListFor<TModel, TProperty>(this HtmlHelper<TModel> html, Expression<Func<TModel, TProperty>> expression, IEnumerable<SelectListItem> selectList, object htmlAttributes, bool enabled)
{
  if (enabled)
  {
    return SelectExtensions.DropDownListFor<TModel, TProperty>(html, expression, selectList, htmlAttributes);
  }

  var htmlAttributesAsDict = HtmlHelper.AnonymousObjectToHtmlAttributes(htmlAttributes);
  htmlAttributesAsDict.Add("disabled", "disabled");
  string selectClientId = html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldId(ExpressionHelper.GetExpressionText(expression));
  htmlAttributesAsDict.Add("id", selectClientId + "_disabled");

  var hiddenFieldMarkup = html.HiddenFor<TModel, TProperty>(expression);
  var selectMarkup = SelectExtensions.DropDownListFor<TModel, TProperty>(html, expression, selectList, htmlAttributesAsDict);
  return MvcHtmlString.Create(selectMarkup.ToString() + Environment.NewLine + hiddenFieldMarkup.ToString());
}

and usage, goal is to disable select if there is just one item in options, markup:

@Html.DropDownListFor(m => m.SomeValue, Model.SomeList, new { @class = "some-class" }, Model.SomeList > 1)

And there is one even more elegant HTML Helper example, no post support for now (pretty straight forward job, just use HAP and add hidden input as root element sibling and swap id's):

public static MvcHtmlString Disable(this MvcHtmlString previous, bool disabled, bool disableChildren = false)
{
  if (disabled)
  {
    var canBeDisabled = new HashSet<string> { "button", "command", "fieldset", "input", "keygen", "optgroup", "option", "select", "textarea" };
    var doc = new HtmlDocument();
    doc.LoadHtml(previous.ToString());
    var rootElements = doc.DocumentNode.Descendants().Where(
      hn => hn.NodeType == HtmlNodeType.Element && 
      canBeDisabled.Contains(hn.Name.ToLower()) && 
      (disableChildren || hn.ParentNode.NodeType == HtmlNodeType.Document));

    foreach (var element in rootElements)
    {
      element.SetAttributeValue("disabled", "");
    }
    string html = doc.DocumentNode.OuterHtml;
    return MvcHtmlString.Create(html);
  }
  return previous;
}

For example there is a model property bool AllInputsDisabled, when true all html inputs should be disabled:

@Html.TextBoxFor(m => m.Address, new { placeholder = "Enter address" }).Disable(Model.AllInputsDisabled)

@Html.DropDownListFor(m => m.DoYou, Model.YesNoList).Disable(Model.AllInputsDisabled)

Use the replace() method of the String object.

As mentioned in the selected answer, the /g flag should be used in the regex, in order to replace all instances of the substring in the string.

Try this

#generic_search_button
{
    float: left;
    width: 24px; /*new width*/
    height: 24px; /*new width*/
    border: none !important; /* no border and override any inline styles*/
    margin-top: 7px;
    cursor: pointer;
    background-color: White;
    background-image: url(/Images/search.png);
    background-repeat: no-repeat;
    background-position: center center;
}

I think the image size might be wrong

If you are using httpclient 4.2, then you need to write a small bit of extra code. I wanted to be able to customize both the "TLS enabled protocols" (e.g. TLSv1.1 specifically, and neither TLSv1 nor TLSv1.2) as well as the cipher suites.

public class CustomizedSSLSocketFactory
    extends SSLSocketFactory
{
    private String[] _tlsProtocols;
    private String[] _tlsCipherSuites;

    public CustomizedSSLSocketFactory(SSLContext sslContext,
                                      X509HostnameVerifier hostnameVerifier,
                                      String[] tlsProtocols,
                                      String[] cipherSuites)
    {
        super(sslContext, hostnameVerifier);

        if(null != tlsProtocols)
            _tlsProtocols = tlsProtocols;
        if(null != cipherSuites)
            _tlsCipherSuites = cipherSuites;
    }

    @Override
    protected void prepareSocket(SSLSocket socket)
    {
        // Enforce client-specified protocols or cipher suites
        if(null != _tlsProtocols)
            socket.setEnabledProtocols(_tlsProtocols);

        if(null != _tlsCipherSuites)
            socket.setEnabledCipherSuites(_tlsCipherSuites);
    }
}

Then:

    SSLContext sslContext = SSLContext.getInstance("TLS");

    sslContext.init(null, getTrustManagers(), new SecureRandom());

    // NOTE: not javax.net.SSLSocketFactory
    SSLSocketFactory sf = new CustomizedSSLSocketFactory(sslContext,
                                                         null,
                                                         [TLS protocols],
                                                         [TLS cipher suites]);

    Scheme httpsScheme = new Scheme("https", 443, sf);
    SchemeRegistry schemeRegistry = new SchemeRegistry();
    schemeRegistry.register(httpsScheme);

    ConnectionManager cm = new BasicClientConnectionManager(schemeRegistry);

    HttpClient client = new DefaultHttpClient(cmgr);
    ...

You may be able to do this with slightly less code, but I mostly copy/pasted from a custom component where it made sense to build-up the objects in the way shown above.

You can use an object as a map:

  var hasName = ({
        "true"  : "Y",
        "false" : "N"
  })[name];

This also scales nicely for many options

  var hasName = ({
        "true"          : "Y",
        "false"         : "N",
        "fileNotFound"  : "O"
  })[name];

(Bonus point for people getting the reference)

Note: you should use actual booleans instead of the string value "true" for your variables indicating truth values.

I just came across this tonight. Can't say if they are legit, how long in business, and whether they'll be around long, but seems interesting. I may give them a try, and will post update if I do.

Per the website, they say they offer hourly pay-as-you-go and weekly/monthly plans, plus there's a free trial.

http://www.macincloud.com

Per @Iterator, posting update on my findings for this service, moving out from my comments:

I did the trial/evaluation. The trial can be misleading on how the trial works. You may need to signup to see prices but the trial so far, per the trial software download, doesn't appear to be time limited. It's just feature restricted. You signup to get your own account, but you actually use a generic trial login account to do the trial, not your own account. Your own account is used when you actually pay for the service. The trial limits what you can do, install, save, etc. but good enough to give you an idea of how things work. So it doesn't hurt to signup to evaluate and not pay anything.

Persistence of data is offered via saving files to DropBox (pre-installed, you just need login/configure), etc. There is no concept of AMIs, EBS, or some VM image. Their service is actually like a shared website hosting solution, where users timeshare a Mac machine (like timesharing a Unix/Linux server), and I think they limit or periodically purge what you put on the machine, or perhaps rather they don't backup your files, hence use of DropBox to do the backup. One should contact them to clarify this if desired.

They have various pricing options, as you mention the all day pass, monthly plans at $20, and their is a pay as you go plan at $1/hr. I'd probably go with pay as you go based on my usage. The pay as you go is based on prepaid credits (1 credit = 1 hour, billed at 30 credit increments). One caveat is that you need to periodically use the plan at least once every 60 days for the pay as you go plan or else you lose unused credits. So that's like minimum of spending 1 credit /1 hour every 60 days.

One last comment for now, from my evaluation, you'll need high bandwidth to use the service effectively. It's usable over 1.5 Mbps DSL but kind of slow in response. You'd want to use it from a corporate network with Gbps bandwidth for optimal use. Or at least a higher speed cable/DSL broadband connection. On my last test ~3Mbps seemed sufficient on the low bandwidth profile (they have multiple bandwidth connection profiles, low, medium, high, optimized for some bandwidth ranges). I didn't test on the higher ones. Your mileage may vary.

From "Find duplicate rows with PostgreSQL" here's smart solution:

select * from (
  SELECT id,
  ROW_NUMBER() OVER(PARTITION BY column1, column2 ORDER BY id asc) AS Row
  FROM tbl
) dups
where 
dups.Row > 1

Found one solution for WIFI (works for Android 4.3, 4.4):

1. Connect to WIFI network (e.g. 'Alex')
2. Settings->WIFI
3. Long tap on connected network's name (e.g. on 'Alex')
4. Modify network config-> Show advanced options
5. Set proxy settings

You can now use ts-node, which makes your life as simple as

npm install -D ts-node
npm install -D typescript

ts-node script.ts

Sorting dictionaries by value using comprehensions. I think it's nice as 1 line and no need for functions or lambdas

a = {'b':'foo', 'c':'bar', 'e': 'baz'}
a = {f:a[f] for f in sorted(a, key=a.__getitem__)}

Also be aware that deleting a base class pointer when there is no virtual destructor will result in undefined behavior. Something that I learned just recently:

How should overriding delete in C++ behave?

I've been using C++ for years and I still manage to hang myself.

if you already have that hidden input :

function product(a, b) {
   return a * b;
}
function setInputValue(input_id, val) {
    document.getElementById(input_id).setAttribute('value', val);
}

if not, you can create one, add it to the body and then set it's value :

function addInput(val) {
    var input = document.createElement('input');
    input.setAttribute('type', 'hidden');
    input.setAttribute('value', val);
    document.body.appendChild(input);
}

And then you can use(depending on the case) :

addInput(product(2, 3)); // if you want to create the input
// or
setInputValue('input_id', product(2, 3)); 

Based on the link provided by @better_use_mkstemp, here's a fiddle where nested iframe resizes to fill parent div: http://jsfiddle.net/orlenko/HNyJS/

Html:

<div id="content">
    <iframe src="http://www.microsoft.com" name="frame2" id="frame2" frameborder="0" marginwidth="0" marginheight="0" scrolling="auto" onload="" allowtransparency="false"></iframe>
</div>
<div id="block"></div>
<div id="header"></div>
<div id="footer"></div>

Relevant parts of CSS:

div#content {
    position: fixed;
    top: 80px;
    left: 40px;
    bottom: 25px;
    min-width: 200px;
    width: 40%;
    background: black;
}

div#content iframe {
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    height: 100%;
    width: 100%;
}

break breaks out of a loop, not an if statement, as others have pointed out. The motivation for this isn't too hard to see; think about code like

for item in some_iterable:
    ...
    if break_condition():
        break 

The break would be pretty useless if it terminated the if block rather than terminated the loop -- terminating a loop conditionally is the exact thing break is used for.

I made this method for creating filenames:

public static String safeChar(String input)
{
    char[] allowed = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ-_".toCharArray();
    char[] charArray = input.toString().toCharArray();
    StringBuilder result = new StringBuilder();
    for (char c : charArray)
    {
        for (char a : allowed)
        {
            if(c==a) result.append(a);
        }
    }
    return result.toString();
}

For most applications, a simple script such as

return /[^.]+$/.exec(filename);

would work just fine (as provided by Tom). However this is not fool proof. It does not work if the following file name is provided:

image.jpg?foo=bar

It may be a bit overkill but I would suggest using a url parser such as this one to avoid failure due to unpredictable filenames.

Using that particular function, you could get the file name like this:

var trueFileName = parse_url('image.jpg?foo=bar').file;

This will output "image.jpg" without the url vars. Then you are free to grab the file extension.

invalidate cache in android studio will resolve this issue. Go to file-> click on invalidate cache/restart option.

User proper model in your controller file.

<?php
namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;
use App\User;

Even if you don't control the server, you can still see the error messages by adding the following line to the Web.config file in your project (bewlow <system.web>):

<customErrors mode="off" />

What happens after login (to which url the user is redirected) is handled by the AuthenticationSuccessHandler.

This interface (a concrete class implementing it is SavedRequestAwareAuthenticationSuccessHandler) is invoked by the AbstractAuthenticationProcessingFilter or one of its subclasses like (UsernamePasswordAuthenticationFilter) in the method successfulAuthentication.

So in order to have an other redirect in case 3 you have to subclass SavedRequestAwareAuthenticationSuccessHandler and make it to do what you want.

Sometimes (depending on your exact usecase) it is enough to enable the useReferer flag of AbstractAuthenticationTargetUrlRequestHandler which is invoked by SimpleUrlAuthenticationSuccessHandler (super class of SavedRequestAwareAuthenticationSuccessHandler).

<bean id="authenticationFilter"
      class="org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter">
    <property name="filterProcessesUrl" value="/login/j_spring_security_check" />
    <property name="authenticationManager" ref="authenticationManager" />
    <property name="authenticationSuccessHandler">
        <bean class="org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler">
            <property name="useReferer" value="true"/>
        </bean>
    </property>
    <property name="authenticationFailureHandler">
        <bean class="org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler">
            <property name="defaultFailureUrl" value="/login?login_error=t" />
        </bean>
    </property>
</bean>

<script>

function getSummary(id)
{
   $.ajax({

     type: "GET",//post
     url: 'Your URL',
     data: "id="+id, // appears as $_GET['id'] @ ur backend side
     success: function(data) {
           // data is ur summary
          $('#summary').html(data);
     }

   });

}
</script>

You could parse the output from the GPRESULT command.

Starting with TypeScript 2.2 using dot notation to access indexed properties is allowed. You won't get error TS2339 on your example.

See Dotted property for types with string index signatures in TypeScript 2.2 release note.

I've modified your plunker to get it working via angular-xeditable:

http://plnkr.co/edit/xUDrOS?p=preview

It is common solution for inline editing - you creale hyperlinks with editable-text directive that toggles into <input type="text"> tag:

<a href="#" editable-text="bday.name" ng-click="myform.$show()" e-placeholder="Name">
    {{bday.name || 'empty'}}
</a>

For date I used editable-date directive that toggles into html5 <input type="date">.

Just pass the list to np.array:

a = np.array(a)

You can also take this opportunity to set the dtype if the default is not what you desire.

a = np.array(a, dtype=...)

It is most efficient to do your aggregation by integer and then convert back to datetime for presentation.

select 
    cast(daybucket - 1 as datetime) as count_date,
    counted_leads
from 
    (select 
         cast(created_date as int) as DayBucket,
         count(*) as counted_leads
     from mytable
     group by cast(created_date as int) ) as countByDay

As javascript is dynamically typed, rather than using the .length property as above you can simply treat the input value as a boolean:

var input = $.trim($("#spa").val());

if (input) {
    // Do Stuff
}

You can also extract the logic out into functions, then by assigning a class and using the each() method the code is more dynamic if, for example, in the future you wanted to add another input you wouldn't need to change any code.

So rather than hard coding the function call into the input markup, you can give the inputs a class, in this example it's test, and use:

$(".test").each(function () {
    $(this).keyup(function () {
        $("#submit").prop("disabled", CheckInputs());
    });
});

which would then call the following and return a boolean value to assign to the disabled property:

function CheckInputs() {
    var valid = false;
    $(".test").each(function () {
        if (valid) { return valid; }
        valid = !$.trim($(this).val());
    });
    return valid;
}

You can see a working example of everything I've mentioned in this JSFiddle.

Did you try using t.Text?

As the official document: As of 1.9, a string is only considered to be HTML if it starts with a less-than ("<") character. The Migrate plugin can be used to restore the pre-1.9 behavior.

If a string is known to be HTML but may start with arbitrary text that is not an HTML tag, pass it to jQuery.parseHTML() which will return an array of DOM nodes representing the markup. A jQuery collection can be created from this, for example: $($.parseHTML(htmlString)). This would be considered best practice when processing HTML templates for example. Simple uses of literal strings such as $("<p>Testing</p>").appendTo("body") are unaffected by this change.

From http://www.dotnetperls.com:

7z a secure.7z * -pSECRET

Where:

7z        : name and path of 7-Zip executable
a         : add to archive
secure.7z : name of destination archive
*         : add all files from current directory to destination archive
-pSECRET  : specify the password "SECRET"

To open :

7z x secure.7z

Then provide the SECRET password

Note: If the password contains spaces or special characters, then enclose it with single quotes

7z a secure.7z * -p"pa$$word @|"

This example subtracts two lists:

# List of pairs of points
list = []
list.append([(602, 336), (624, 365)])
list.append([(635, 336), (654, 365)])
list.append([(642, 342), (648, 358)])
list.append([(644, 344), (646, 356)])
list.append([(653, 337), (671, 365)])
list.append([(728, 13), (739, 32)])
list.append([(756, 59), (767, 79)])

itens_to_remove = []
itens_to_remove.append([(642, 342), (648, 358)])
itens_to_remove.append([(644, 344), (646, 356)])

print("Initial List Size: ", len(list))

for a in itens_to_remove:
    for b in list:
        if a == b :
            list.remove(b)

print("Final List Size: ", len(list))

I think this would be a better way to do it in Swift:

func filterContentForSearchText(searchText:NSString, scope:NSString)
{
   searchResults = recipes.filter { name.rangeOfString(searchText) != nil  }
}

I using Xcode 6+ and I just do:

• Copy all files in project folders to new Folders (with new name).
• Open *.xcodeproj or *.xcworkspace
• Change name of Project.
• Click on schema and delete current chema and add new one.

Here is done, but name of window Xcode and *.xcodeproj or *.xcworkspace still <old-name>. Then I do:

• pop install
• Open <new name>.xcworkspace

A many to many relationship normally has a linking table. Consider this "link" as an entity in its own right and give it a unique id, then send that id in the delete request.

You would have a a REST resource URL like /user/role to handle operations on a user-role "link" entity.

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill';

If you want to make sure the current value is indeed 203 (and not accidently increase it again) you can also add another condition:

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill'
  AND total = 203;

I know this is an old post but as MisterZimbu stated, the color property is defining the values of other properties, as the border-color and, with CSS3, of currentColor.

currentColor is very handy if you want to use the font color for other elements (as the background or custom checkboxes and radios of inner elements for example).

Example:

.element {_x000D_
  color: green;_x000D_
  background: red;_x000D_
  display: block;_x000D_
  width: 200px;_x000D_
  height: 200px;_x000D_
  padding: 0;_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
.innerElement1 {_x000D_
  border: solid 10px;_x000D_
  display: inline-block;_x000D_
  width: 60px;_x000D_
  height: 100px;_x000D_
  margin: 10px;_x000D_
}_x000D_
_x000D_
.innerElement2 {_x000D_
  background: currentColor;_x000D_
  display: inline-block;_x000D_
  width: 60px;_x000D_
  height: 100px;_x000D_
  margin: 10px;_x000D_
}

<div class="element">_x000D_
  <div class="innerElement1"></div>_x000D_
  <div class="innerElement2"></div>_x000D_
</div>

the css you are showing must be applied to a block element, like a div. So :

<div id="#rectangle"></div>

Since the static method 'GetAccessControl' seems to be missing from the present version of .Net core/Standard I had to modify @Bryce Wagner's answer (I went ahead and used more modern syntax):

public static class PermissionHelper
{
  public static bool? CurrentUserHasWritePermission(string filePath)

     => new WindowsPrincipal(WindowsIdentity.GetCurrent())
        .SelectWritePermissions(filePath)
        .FirstOrDefault();


  private static IEnumerable<bool?> SelectWritePermissions(this WindowsPrincipal user, string filePath)
     => from rule in filePath
                    .GetFileSystemSecurity()
                    .GetAccessRules(true, true, typeof(NTAccount))
                    .Cast<FileSystemAccessRule>()
        let right = user.HasRightSafe(rule)
        where right.HasValue
        // Deny takes precedence over allow
        orderby right.Value == false descending
        select right;


  private static bool? HasRightSafe(this WindowsPrincipal user, FileSystemAccessRule rule)
  {
     try
     {
        return user.HasRight(rule);
     }
     catch
     {
        return null;
     }
  }

  private static bool? HasRight(this WindowsPrincipal user,FileSystemAccessRule rule )
     => rule switch

        { FileSystemRights: FileSystemRights fileSystemRights } when (fileSystemRights &
                                                                      (FileSystemRights.WriteData | FileSystemRights.Write)) == 0 => null,
        { IdentityReference: { Value: string value } } when value.StartsWith("S-1-") &&
