Accepted Answer is correct, but it didn't fully work for me. I had to delete the package.lock file, re-run "npm install", and then close and reopen my visual studio. Hope this helps someone

Taking for granted that the JSON you posted is actually what you are seeing in the browser, then the problem is the JSON itself.

The JSON snippet you have posted is malformed.

You have posted:

[{
        "name" : "shopqwe",
        "mobiles" : [],
        "address" : {
            "town" : "city",
            "street" : "streetqwe",
            "streetNumber" : "59",
            "cordX" : 2.229997,
            "cordY" : 1.002539
        },
        "shoe"[{
                "shoeName" : "addidas",
                "number" : "631744030",
                "producent" : "nike",
                "price" : 999.0,
                "sizes" : [30.0, 35.0, 38.0]
            }]

while the correct JSON would be:

[{
        "name" : "shopqwe",
        "mobiles" : [],
        "address" : {
            "town" : "city",
            "street" : "streetqwe",
            "streetNumber" : "59",
            "cordX" : 2.229997,
            "cordY" : 1.002539
        },
        "shoe" : [{
                "shoeName" : "addidas",
                "number" : "631744030",
                "producent" : "nike",
                "price" : 999.0,
                "sizes" : [30.0, 35.0, 38.0]
            }
        ]
    }

You need to use HAVING, not WHERE.

The difference is: the WHERE clause filters which rows MySQL selects. Then MySQL groups the rows together and aggregates the numbers for your COUNT function.

HAVING is like WHERE, only it happens after the COUNT value has been computed, so it'll work as you expect. Rewrite your subquery as:

(                  -- where that pid is in the set:
SELECT c2.pid                  -- of pids
FROM Catalog AS c2             -- from catalog
WHERE c2.pid = c1.pid
HAVING COUNT(c2.sid) >= 2)

Let's say we need to find count of multiple words in a file testfile. There are two ways to go about it

1) Use grep command with regex matching pattern

grep -c '\<\(DOG\|CAT\)\>' testfile

2) Use egrep command

egrep -c 'DOG|CAT' testfile 

With egrep you need not to worry about expression and just separate words by a pipe separator.

No matter what we tried we couldn't manage to get the timeout below 21 seconds when the server we were checking was down.

To work around this we combined a TcpClient check to see if the domain was alive followed by a separate check to see if the URL was active

public static bool IsUrlAlive(string aUrl, int aTimeoutSeconds)
{
    try
    {
        //check the domain first
        if (IsDomainAlive(new Uri(aUrl).Host, aTimeoutSeconds))
        {
            //only now check the url itself
            var request = System.Net.WebRequest.Create(aUrl);
            request.Method = "HEAD";
            request.Timeout = aTimeoutSeconds * 1000;
            var response = (HttpWebResponse)request.GetResponse();
            return response.StatusCode == HttpStatusCode.OK;
        }
    }
    catch
    {
    }
    return false;

}

private static bool IsDomainAlive(string aDomain, int aTimeoutSeconds)
{
    try
    {
        using (TcpClient client = new TcpClient())
        {
            var result = client.BeginConnect(aDomain, 80, null, null);

            var success = result.AsyncWaitHandle.WaitOne(TimeSpan.FromSeconds(aTimeoutSeconds));

            if (!success)
            {
                return false;
            }

            // we have connected
            client.EndConnect(result);
            return true;
        }
    }
    catch
    {
    }
    return false;
}

Using a cookie to provide the CSRF token to the client does not allow a successful attack because the attacker cannot read the value of the cookie and therefore cannot put it where the server-side CSRF validation requires it to be.

The attacker will be able to cause a request to the server with both the auth token cookie and the CSRF cookie in the request headers. But the server is not looking for the CSRF token as a cookie in the request headers, it's looking in the payload of the request. And even if the attacker knows where to put the CSRF token in the payload, they would have to read its value to put it there. But the browser's cross-origin policy prevents reading any cookie value from the target website.

The same logic does not apply to the auth token cookie, because the server is expects it in the request headers and the attacker does not have to do anything special to put it there.

You can, using CSS variables (more precisely called CSS custom properties).

• Set your variable in your style attribute:
  style="--my-color-var: orange;"
• Use the variable in your stylesheet:
  background-color: var(--my-color-var);

Browser compatibility

Minimal example:

div {
  width: 100px;
  height: 100px;
  position: relative;
  border: 1px solid black;
}

div:after {
  background-color: var(--my-color-var);
  content: '';
  position: absolute;
  top: 0;
  bottom: 0;
  right: 0;
  left: 0;
}

<div style="--my-color-var: orange;"></div>

Your example:

.bubble {
  position: relative;
  width: 30px;
  height: 15px;
  padding: 0;
  background: #FFF;
  border: 1px solid #000;
  border-radius: 5px;
  text-align: center;
  background-color: var(--bubble-color);
}

.bubble:after {
  content: "";
  position: absolute;
  top: 4px;
  left: -4px;
  border-style: solid;
  border-width: 3px 4px 3px 0;
  border-color: transparent var(--bubble-color);
   display: block;
  width: 0;
  z-index: 1;
  
}

.bubble:before {
  content: "";
  position: absolute;
  top: 4px;
  left: -5px;
  border-style: solid;
  border-width: 3px 4px 3px 0;
  border-color: transparent #000;
  display: block;
  width: 0;
  z-index: 0;
}

<div class='bubble' style="--bubble-color: rgb(100,255,255);"> 100 </div>

if by Blue Border thats on top of the Window Form you mean titlebar, set Forms ControlBox property to false and Text property to empty string ("").

here's a snippet:

this.ControlBox = false;
this.Text = String.Empty;

A variable will never be an integer type in JavaScript — it doesn't distinguish between different types of Number.

You can test if the variable contains a number, and if that number is an integer.

(typeof foo === "number") && Math.floor(foo) === foo

If the variable might be a string containing an integer and you want to see if that is the case:

foo == parseInt(foo, 10)

You need to do two things:

• Start the thread
• Wait for the thread to finish (die) before proceeding

ie

one.start();
one.join();

If you don't start() it, nothing will happen - creating a Thread doesn't execute it.

If you don't join) it, your main thread may finish and exit and the whole program exit before the other thread has been scheduled to execute. It's indeterminate whether it runs or not if you don't join it. The new thread may usually run, but may sometimes not run. Better to be certain.

Make sure that the "Distributed Transaction Coordinator" Service is running on both database and client. Also make sure you check "Network DTC Access", "Allow Remote Client", "Allow Inbound/Outbound" and "Enable TIP".

To enable Network DTC Access for MS DTC transactions

1. Open the Component Services snap-in.

   To open Component Services, click Start. In the search box, type dcomcnfg, and then press ENTER.

2. Expand the console tree to locate the DTC (for example, Local DTC) for which you want to enable Network MS DTC Access.

3. On the Action menu, click Properties.

4. Click the Security tab and make the following changes: In Security Settings, select the Network DTC Access check box.

   In Transaction Manager Communication, select the Allow Inbound and Allow Outbound check boxes.

Found the answer, use android.support.design:hintTextAppearance attribute to set your own floating label appearance.

Example:

<android.support.design.widget.TextInputLayout

    android:layout_height="wrap_content"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    app:hintTextAppearance="@style/TextAppearance.AppCompat">

    <EditText
        android:id="@+id/password"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="@string/prompt_password"/>
</android.support.design.widget.TextInputLayout>

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

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

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

Python 3.6 windows7: There is several way to launch a python you could use the python console (which has a python logo on it) or the windows console (it's written cmd.exe on it).

I could not print utf8 characters in the windows console. Printing utf-8 characters throw me this error:

OSError: [winError 87] The paraneter is incorrect 
Exception ignored in: (_io-TextIOwrapper name='(stdout)' mode='w' ' encoding='utf8') 
OSError: [WinError 87] The parameter is incorrect 

After trying and failing to understand the answer above I discovered it was only a setting problem. Right click on the top of the cmd console windows, on the tab font chose lucida console.

In current version of Jekyll, it defaults to http://127.0.0.1:4000/.
This is good, if you are connected to a network but do not want anyone else to access your application.

However it may happen that you want to see how your application runs on a mobile or from some other laptop/computer.

In that case, you can use

jekyll serve --host 0.0.0.0

This binds your application to the host & next use following to connect to it from some other host

http://host's IP adress/4000 

Here's how to get it with no effect on the original ARRAY

a = [1,2,5,6,1,874,98,"abc"];
a.length; //returns 8 elements

If you use pop(), it will modify your array

a.pop();  // will return "abc" AND REMOVES IT from the array 
a.length; // returns 7

But you can use this so it has no effect on the original array:

a.slice(-1).pop(); // will return "abc" won't do modify the array 
                   // because slice creates a new array object 
a.length;          // returns 8; no modification and you've got you last element 

Here is an alternative. Create a generic exception that takes a status code and a message. Then create an exception handler. Use the exception handler to retrieve the information out of the exception and return to the caller of the service.

http://javaninja.net/2016/06/throwing-exceptions-messages-spring-mvc-controller/

public class ResourceException extends RuntimeException {

    private HttpStatus httpStatus = HttpStatus.INTERNAL_SERVER_ERROR;

    public HttpStatus getHttpStatus() {
        return httpStatus;
    }

    /**
     * Constructs a new runtime exception with the specified detail message.
     * The cause is not initialized, and may subsequently be initialized by a
     * call to {@link #initCause}.
     * @param message the detail message. The detail message is saved for later retrieval by the {@link #getMessage()}
     *                method.
     */
    public ResourceException(HttpStatus httpStatus, String message) {
        super(message);
        this.httpStatus = httpStatus;
    }
}

Then use an exception handler to retrieve the information and return it to the service caller.

@ControllerAdvice
public class ExceptionHandlerAdvice { 

    @ExceptionHandler(ResourceException.class)
    public ResponseEntity handleException(ResourceException e) {
        // log exception 
        return ResponseEntity.status(e.getHttpStatus()).body(e.getMessage());
    }         
} 

Then create an exception when you need to.

throw new ResourceException(HttpStatus.NOT_FOUND, "We were unable to find the specified resource.");

The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:

ffmpeg -i input.mov -qscale 0 output.mp4

Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0):

ffmpeg -i input.mov -q:v 0 output.mp4

If you want to map objects to something (in this case a property). I think Array.prototype.map is what you're looking for if you want to code functionally.

[
  {name: "Joe", age: 22},
  {name: "Kevin", age: 24},
  {name: "Peter", age: 21}
].map(function(elem){
    return elem.name;
}).join(",");

In modern JavaScript:

[
  {name: "Joe", age: 22},
  {name: "Kevin", age: 24},
  {name: "Peter", age: 21}
].map(e => e.name).join(",");

(fiddle)

If you want to support older browsers, that are not ES5 compliant you can shim it (there is a polyfill on the MDN page above). Another alternative would be to use underscorejs's pluck method:

var users = [
      {name: "Joe", age: 22},
      {name: "Kevin", age: 24},
      {name: "Peter", age: 21}
    ];
var result = _.pluck(users,'name').join(",")

You application of js and php in totally invalid.

You have to understand a fact that JS runs on clientside, once the page loads it does not care, whether the page was a php page or jsp or asp. It executes of DOM and is related to it only.

However you can do something like this

var newLocation = "<?php echo $newlocation; ?>";
window.location = newLocation;

You see, by the time the script is loaded, the above code renders into different form, something like this

var newLocation = "your/redirecting/page.php";
window.location = newLocation;

Like above, there are many possibilities of php and js fusions and one you are doing is not one of them.

Use blur event to call your function when element loses focus :

$('#filter').blur(function() {
  $('#options').hide();
});

A simple solution that i use, works from IE8+

Give min-height:100% on html so that if content is less then still page takes full view-port height and footer sticks at bottom of page. When content increases the footer shifts down with content and keep sticking to bottom.

1. Prepare your own hosts file you wish to add to docker container;

1.2.3.4 abc.tv
5.6.7.8 domain.xyz
1.3.5.7 odd.org
2.4.6.8 even.net

2. COPY your hosts file into the container by adding the following line in the Dockerfile

COPY hosts /etc/hosts_extra

3. If you know how to use ENTRYPOINT or CMD or CRON job then incorporate the following command line into it or at least run this inside the running container:

cat /etc/hosts_extra >> etc/hosts;

4. You cannot add the following in the Dockerfile because the modification will be lost:

RUN cat /etc/hosts_extra >> etc/hosts;

Using current browsers you can use it like this:

img {
  -webkit-filter: grayscale(100%); /* Chrome, Safari, Opera */
  filter: grayscale(100%);
}

and to remedy it:

img:hover{
   -webkit-filter: grayscale(0%); /* Chrome, Safari, Opera */
   filter: grayscale(0%);
}

worked with me and is much shorter. There is even more one can do within the CSS:

filter: none | blur() | brightness() | contrast() | drop-shadow() | grayscale() |
        hue-rotate() | invert() | opacity() | saturate() | sepia() | url();

For more information and supporting browsers see this: http://www.w3schools.com/cssref/css3_pr_filter.asp

My case is not mentioned here:
I have to run the web project on a fake domain (settup on IIS and /hosts/etc) because of the callbacks from a third party site.

I was seeing two w3wp processes in the process list of VS:
w3wp.exe User Name: IIS APPPOOL\Default app pool
w3wp.exe User Name: IIS APPPOOL.svc

I had to to manually attach to second one to be able to debug.

So I realised the app pool of my Fake domain in iis is not set to "Default app pool"

https://manage.accuwebhosting.com/knowledgebase/2532/How-to-change-application-pool-from-IIS.html

As soon as I changed the domain's app pool to the "Default app pool" visual studio started to debug the web app.

Your root logger definition is a bit confused. See the log4j documentation.

This is a standard Java properties file, which means that lines are treated as key=value pairs. Your second log4j.rootLogger line is overwriting the first, which explains why you aren't seeing anything on the console appender.

You need to merge your two rootLogger definitions into one. It looks like you're trying to have DEBUG messages go to the console and INFO messages to the file. The root logger can only have one level, so you need to change your configuration so that the appenders have appropriate levels.

While I haven't verified that this is correct, I'd guess it'll look something like this:

log4j.rootLogger=DEBUG,console,file
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.file=org.apache.log4j.RollingFileAppender

Note that you also have an error in casing - you have console lowercase in one place and in CAPS in another.

In the year 2020 / 2021 it is even easier with Array.from to 'convert' from a array-like nodes to an actual array, and then using .map to loop through the resulting array. The code is as simple as the follows:

Array.from(tableFields.children).map((child)=>console.log(child))

std::fill is one way. Takes two iterators and a value to fill the region with. That, or the for loop, would (I suppose) be the more C++ way.

For setting an array of primitive integer types to 0 specifically, memset is fine, though it may raise eyebrows. Consider also calloc, though it's a bit inconvenient to use from C++ because of the cast.

For my part, I pretty much always use a loop.

(I don't like to second-guess people's intentions, but it is true that std::vector is, all things being equal, preferable to using new[].)

Another modelling tool for Java is (my) website GitUML. Generate UML diagrams from Java or Python code stored in GitHub repositories.

One key idea with GitUML is to address one of the problems with "documentation": that diagrams are always out of date. With GitUML, diagrams automatically update when you push code using git.

Browse through community UML diagrams, there are some Java design patterns there. Surf through popular GitHub repositories and visualise the architectures and patterns in them.

Create diagrams using point and click. There is no drag drop editor, just click on the classes in the repository tree that you want to visualise:

The underlying technology is PlantUML based, which means you can refine your diagrams with additional PlantUML markup.

When creating the TABLE under B2BOWNER, be sure to prefix the PL/SQL function with the Schema name; i.e. B2BOWNER.F_SSC_Page_Map_Insert.

I did not realize this until the DBAs pointed it out. I could have created the table under my root USER/SCHEMA and the PL/SQL function would have worked fine.

Dictionary objects allow you to iterate over their items. Also, with pattern matching and the division from __future__ you can do simplify things a bit.

Finally, you can separate your logic from your printing to make things a bit easier to refactor/debug later.

            yield win_percentage

    for win_percentage in win_percentages():
        print win_percentage

It's much easier to do like this:

if(!$('#foo').hasClass('bar')) { 
  ...
}

The ! in front of the criteria means false, works in most programming languages.

Everytime I install node.js it needs a reboot and then the path is recognized.

You have two approaches to this:

1. check the "keypress" event. If the user presses a special character key, stop him right there
2. check the "onblur" event: when the input element loses focus, validate its contents. If the value is invalid, display a discreet warning beside that input box.

I would suggest the second method because its less irritating. Remember to also check onpaste . If you use only keypress Then We Can Copy and paste special characters so use onpaste also to restrict Pasting special characters

Additionally, I will also suggest that you reconsider if you really want to prevent users from entering special characters. Because many people have $, #, @ and * in their passwords.

I presume that this might be in order to prevent SQL injection; if so: its better that you handle the checks server-side. Or better still, escape the values and store them in the database.

The current directory is a system-level feature; it returns the directory that the server was launched from. It has nothing to do with the website.

You want HttpRuntime.AppDomainAppPath.

If you're in an HTTP request, you can also call Server.MapPath("~/Whatever").

Copying to the clipboard is a tricky task to do in Javascript in terms of browser compatibility. The best way to do it is using a small flash. It will work on every browser. You can check it in this article.

Here's how to do it for Internet Explorer:

function copy (str)
{
    //for IE ONLY!
    window.clipboardData.setData('Text',str);
}

you can use numpy.argsort

or you can do:

test =  [2,3,1,4,5]
idxs = list(zip(*sorted([(val, i) for i, val in enumerate(test)])))[1]

zip will rearange the list so that the first element is test and the second is the idxs.

To answer your first question: yes it is feasible to develop an android application in pure python, in order to achieve this I suggest you use BeeWare, which is just a suite of python tools, that work together very well and they enable you to develop platform native applications in python.

checkout this video by the creator of BeeWare that perfectly explains and demonstrates it's application

How it works

Android's preferred language of implementation is Java - so if you want to write an Android application in Python, you need to have a way to run your Python code on a Java Virtual Machine. This is what VOC does. VOC is a transpiler - it takes Python source code, compiles it to CPython Bytecode, and then transpiles that bytecode into Java-compatible bytecode. The end result is that your Python source code files are compiled directly to a Java .class file, which can be packaged into an Android application.

VOC also allows you to access native Java objects as if they were Python objects, implement Java interfaces with Python classes, and subclass Java classes with Python classes. Using this, you can write an Android application directly against the native Android APIs.

Once you've written your native Android application, you can use Briefcase to package your Python code as an Android application.

Briefcase is a tool for converting a Python project into a standalone native application. You can package projects for:

• Mac
• Windows
• Linux
• iPhone/iPad
• Android
• AppleTV
• tvOS.

You can check This native Android Tic Tac Toe app written in Python, using the BeeWare suite. on GitHub

in addition to the BeeWare tools, you'll need to have a JDK and Android SDK installed to test run your application.

and to answer your second question: a good environment can be anything you are comfortable with be it a text editor and a command line, or an IDE, if you're looking for a good python IDE I would suggest you try Pycharm, it has a community edition which is free, and it has a similar environment as android studio, due to to the fact that were made by the same company.

I hope this has been helpful

Use DecimalFormat.

DecimalFormat is a concrete subclass of NumberFormat that formats decimal numbers. It has a variety of features designed to make it possible to parse and format numbers in any locale, including support for Western, Arabic, and Indic digits. It also supports different kinds of numbers, including integers (123), fixed-point numbers (123.4), scientific notation (1.23E4), percentages (12%), and currency amounts ($123). All of these can be localized.

Code snippet -

double i2=i/60000;
tv.setText(new DecimalFormat("##.##").format(i2));

Output -

5.81

For the following HTML document:

<html>
  <body>
    <a href="http://www.example.com">Example</a> 
    <a href="http://www.stackoverflow.com">SO</a> 
  </body>
</html>

The xpath query /html/body//a/@href (or simply //a/@href) will return:

    http://www.example.com
    http://www.stackoverflow.com

To select a specific instance use /html/body//a[N]/@href,

    $ /html/body//a[2]/@href
    http://www.stackoverflow.com

To test for strings contained in the attribute and return the attribute itself place the check on the tag not on the attribute:

    $ /html/body//a[contains(@href,'example')]/@href
    http://www.example.com

Mixing the two:

    $ /html/body//a[contains(@href,'com')][2]/@href
    http://www.stackoverflow.com

Because the Javascript executes in the browser, on the client side, and PHP on the server side, what you need is AJAX - in essence, your script makes an HTTP request to a PHP script, passing any required parameters. The script calls your function, and outputs the result, which ultimately gets picked up by the Ajax call. Generally, you don't do this synchronously (waiting for the result) - the 'A' in AJAX stands for asynchronous!

They are, however not supported by many fonts (fileformat.info only lists a few fonts as supporting the Codepoint with a proper glyph).

Also note that they are outside of the BMP, so some Unicode-capable software might have problems rendering them, even if they have fonts that support them.

Generally Unicode Glyphs can be searched using a site such as fileformat.info. This searches "only" in the names and properties of the Unicode glyphs, but they usually contain enough metadata to allow for good search results (for this answer I searched for "glass" and browsed the resulting list, for example)

A new display value seems to the job in one line.

display: flow-root;

From the W3 spec: "The element generates a block container box, and lays out its contents using flow layout. It always establishes a new block formatting context for its contents."

Information: https://www.w3.org/TR/css-display-3/#valdef-display-flow-root https://www.chromestatus.com/feature/5769454877147136

?As shown in the link above, support is currently limited so fallback support like below may be of use: https://github.com/fliptheweb/postcss-flow-root

I don't think your question is very clear, this code assumes that if you're going to include the -domain parameter, it's always 'named' (i.e. dostuff computername arg2 -domain domain); this also makes the computername parameter mandatory.

Function DoStuff(){
    param(
        [Parameter(Mandatory=$true)][string]$computername,
        [Parameter(Mandatory=$false)][string]$arg2,
        [Parameter(Mandatory=$false)][string]$domain
    )
    if(!($domain)){
        $domain = 'domain1'
    }
    write-host $domain
    if($arg2){
        write-host "arg2 present... executing script block"
    }
    else{
        write-host "arg2 missing... exiting or whatever"
    }
}

I had a simular issue and resolved it using android:adjustViewBounds="true" on the ImageView.

Thanks, Max S. conda-forge worked for me as well.

scikit-learn on Anaconda-Jupyter Notebook.

Upgrading my scikit-learn from 0.19.1 to 0.19.2 in anaconda installed on Ubuntu on Google VM instance:

Run the following commands in the terminal:

First, check available the packages with versions

conda list    

It will show packages and their installed versions in the output:

scikit-learn              0.19.1           py36hedc7406_0  

Upgrade to 0.19.2 July 2018 release.

conda config --append channels conda-forge
conda install scikit-learn=0.19.2

Now check the version installed correctly or not?

conda list 

Output is:

scikit-learn              0.19.2          py36_blas_openblasha84fab4_201  [blas_openblas]  conda-forge

Note: Don't use pip command if you are using Anaconda or Miniconda

I tried following commands:

!conda update conda 
!pip install -U scikit-learn

It will install the required packages also will show in the conda list but when try to import that package it will not work.

On the website http://scikit-learn.org/stable/install.html it is mentioned as: Warning To upgrade or uninstall scikit-learn installed with Anaconda or conda you should not use the pip.

The correct way to use LOCK TABLES and UNLOCK TABLES with transactional tables, such as InnoDB tables, is to begin a transaction with SET autocommit = 0 (not START TRANSACTION) followed by LOCK TABLES, and to not call UNLOCK TABLES until you commit the transaction explicitly. For example, if you need to write to table t1 and read from table t2, you can do this:

SET autocommit=0;
LOCK TABLES t1 WRITE, t2 READ, ...;... do something with tables t1 and t2 here ...
COMMIT;
UNLOCK TABLES;

I had the very same problem under Delphi. And the end result was that my own application was locking the directory I wanted to delete. Somehow the directory got locked when I was writing to it (some temporary files).

The catch 22 was, I made a simple change directory to it's parent before deleting it.

I use the following method to grab embedded resources:

    protected static Stream GetResourceStream(string resourcePath)
    {
        Assembly assembly = Assembly.GetExecutingAssembly();
        List<string> resourceNames = new List<string>(assembly.GetManifestResourceNames());

        resourcePath = resourcePath.Replace(@"/", ".");
        resourcePath = resourceNames.FirstOrDefault(r => r.Contains(resourcePath));

        if (resourcePath == null)
            throw new FileNotFoundException("Resource not found");

        return assembly.GetManifestResourceStream(resourcePath);
    }

I then call this with the path in the project:

GetResourceStream(@"DirectoryPathInLibrary/Filename")

void print_ulong_bin(const unsigned long * const var, int bits) {
        int i;

        #if defined(__LP64__) || defined(_LP64)
                if( (bits > 64) || (bits <= 0) )
        #else
                if( (bits > 32) || (bits <= 0) )
        #endif
                return;

        for(i = 0; i < bits; i++) { 
                printf("%lu", (*var >> (bits - 1 - i)) & 0x01);
        }
}

should work - untested.

If you like the idea of Views, but are worried about performance you can get Oracle to create a cached table representing the view which oracle keeps up to date.
See materialized views

The best way is checking out the changes.

Changing the file pom.xml in a project named project-name you can do it:

git status

# modified:   project-name/pom.xml

git checkout project-name/pom.xml
git checkout master

# Checking out files: 100% (491/491), done.
# Branch master set up to track remote branch master from origin.
# Switched to a new branch 'master'

Since bootstrap 4 use div class="form-row" in combination with div class="form-group col-X". X is the width you need. You will get nice inline columns. See fiddle.

<form class="form-horizontal" name="FORMNAME" method="post" action="ACTION" enctype="multipart/form-data">
    <div class="form-group">
        <label class="control-label col-sm-2" for="naam">Naam:&nbsp;*</label>
        <div class="col-sm-10">
            <input type="text" require class="form-control" id="naam" name="Naam" placeholder="Uw naam" value="{--NAAM--}" >
            <div id="naamx" class="form-error form-hidden">Wat is uw naam?</div>
        </div>
    </div>

    <div class="form-row">

        <div class="form-group col-5">
            <label class="control-label col-sm-4" for="telefoon">Telefoon:&nbsp;*</label>
            <div class="col-sm-12">
                <input type="tel" require class="form-control" id="telefoon" name="Telefoon" placeholder="Telefoon nummer" value="{--TELEFOON--}" >

            </div>
        </div>

        <div class="form-group col-5">
            <label class="control-label col-sm-4" for="email">E-mail: </label>
            <div class="col-sm-12">

jQuery.ajax()

Description: Perform an asynchronous HTTP (Ajax) request.

The full monty, lets you make any kind of Ajax request.

http://api.jquery.com/jQuery.get/

jQuery.get()

Description: Load data from the server using a HTTP GET request.

Only lets you make HTTP GET requests, requires a little less configuration.

http://api.jquery.com/load/

.load()

Description: Load data from the server and place the returned HTML into the matched element.

Specialized to get data and inject it into an element.

The del statement removes an element:

del d[key]

Note that this mutates the existing dictionary, so the contents of the dictionary changes for anybody else who has a reference to the same instance. To return a new dictionary, make a copy of the dictionary:

def removekey(d, key):
    r = dict(d)
    del r[key]
    return r

The dict() constructor makes a shallow copy. To make a deep copy, see the copy module.

Note that making a copy for every dict del/assignment/etc. means you're going from constant time to linear time, and also using linear space. For small dicts, this is not a problem. But if you're planning to make lots of copies of large dicts, you probably want a different data structure, like a HAMT (as described in this answer).

Here are the various ways you may pull this (depending on your needs).

Using the Time DataType:

DECLARE @Time Time = '15:04:46.217'
SELECT --'3:04PM'
       CONVERT(VarChar(7), @Time, 0),

       --' 3:04PM' --Leading Space.
       RIGHT(' ' + CONVERT(VarChar(7), @Time, 0), 7),

       --' 3:04 PM' --Space before AM/PM.
       STUFF(RIGHT(' ' + CONVERT(VarChar(7), @Time, 0), 7), 6, 0, ' '),

       --'03:04 PM' --Leading Zero.  This answers the question above.
       STUFF(RIGHT('0' + CONVERT(VarChar(7), @Time, 0), 7), 6, 0, ' ')

       --'03:04 PM' --This only works in SQL Server 2012 and above.  :)
       ,FORMAT(CAST(@Time as DateTime), 'hh:mm tt')--Comment out for SS08 or less.

Using the DateTime DataType:

DECLARE @Date DateTime = '2016-03-17 15:04:46.217'
SELECT --' 3:04PM' --No space before AM/PM.
       RIGHT(CONVERT(VarChar(19), @Date, 0), 7),

       --' 3:04 PM' --Space before AM/PM.
       STUFF(RIGHT(CONVERT(VarChar(19), @Date, 0), 7), 6, 0, ' '),

       --'3:04 PM' --No Leading Space.
       LTRIM(STUFF(RIGHT(CONVERT(VarChar(19), @Date, 0), 7), 6, 0, ' ')),

       --'03:04 PM' --Leading Zero.
       STUFF(REPLACE(RIGHT(CONVERT(VarChar(19), @Date, 0), 7), ' ', '0'), 6, 0, ' ')

       --'03:04 PM' --This only works in SQL Server 2012 and above.  :)
       ,FORMAT(@Date, 'hh:mm tt')--Comment line out for SS08 or less.

To avoid deprecated code and warnings you can use:

view.getViewTreeObserver().addOnGlobalLayoutListener(
        new ViewTreeObserver.OnGlobalLayoutListener() {
            @SuppressWarnings("deprecation")
            @Override
            public void onGlobalLayout() {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                    view.getViewTreeObserver()
                            .removeOnGlobalLayoutListener(this);
                } else {
                    view.getViewTreeObserver()
                            .removeGlobalOnLayoutListener(this);
                }
                yourFunctionHere();
            }
        });

$('div').attr('style', '');

or

$('div').removeAttr('style'); (From Andres's Answer)

To make this a little smaller, try this:

$('div[style]').removeAttr('style');

This should speed it up a little because it checks that the divs have the style attribute.

Either way, this might take a little while to process if you have a large amount of divs, so you might want to consider other methods than javascript.

Fascinating to see how many different causes there are for this issue!

Many say it's a Chrome issue, so I tried Safari and still had issues. Then tried all solutions in this thread, including turning off my AVG Realtime Protection, no luck.

For me, the issue was my .htaccess file. All it contained was FallbackResource index.php, but when I renamed it to htaccess.txt, my issue was resolved.

import re
p = re.compile("[a-z]")
for m in p.finditer('a1b2c3d4'):
    print(m.start(), m.group())

If you have a function like:

int foo()
{
    // more stuff
    foo();
}

Then foo() will keep calling itself, getting deeper and deeper, and when the space used to keep track of what functions you're in is filled up, you get the stack overflow error.

GPS will be used if the user has allowed it to be used in its settings.

You can't explicitly switch this on anymore, but you don't have to - it's a privacy setting really, so you don't want to tweak it. If the user is OK with apps getting precise co-ordinates it'll be on. Then the location manager API will use GPS if it can.

If your app really isn't useful without GPS, and it's off, you can open the settings app at the right screen using an intent so the user can enable it.

As a workaround I've been returning the last object in the array that you get back from the function... It is not a great solution, but it's better than nothing:

someFunction {
   $a = "hello"
   "Function is running"
   return $a
}

$b = someFunction
$b = $b[($b.count - 1)]  # Or
$b = $b[-1]              # Simpler

All in all, a more one-lineish way of writing the same thing could be:

$b = (someFunction $someParameter $andAnotherOne)[-1]

lets say you want to install scipy,

Here is the code to install it

!pip install scipy

There are two ways to hide video tag controls

1. Remove the controls attribute from the video tag.

2. Add the css to the video tag

   video::-webkit-media-controls-panel {
   display: none !important;
   opacity: 1 !important;}
   

I want to add this note to what said above.

Suppose you are using Spring Rest with this simple architect:

Controller <-> Service <-> Repository

And you want to return some data to the front-end, if you are using FetchType.LAZY, you will get an exception after you return data to the controller method since the session is closed in the Service so the JSON Mapper Object can't get the data.

There is three common options to solve this problem, depends on the design, performance and the developer:

1. The easiest one is to use FetchType.EAGER, So that the session will still alive at the controller method, but this method will impact the performance.
2. Anti-patterns solutions, to make the session live until the execution ends, it is make a huge performance issue in the system.
3. The best practice is to use FetchType.LAZY with mapper like MapStruct to transfer data from Entity to another data object DTO and then send it back to the controller, so there is no exception if the session closed.

:1,.d deletes lines 1 to current.
:1,.-1d deletes lines 1 to above current.

(Personally I'd use dgg or kdgg like the other answers, but TMTOWTDI.)

Ran into the same problem myself, but my controller definitions looked a little different than above. For controllers defined like this:

function MyController($scope, $http) {
    // ...
}

Just add a line after the declaration indicating which objects to inject when the controller is instantiated:

function MyController($scope, $http) {
    // ...
}
MyController.$inject = ['$scope', '$http'];

This makes it minification-safe.

You can also use the command line, Change directory where your folder is located then type the following :

     git init
     git add <folder1> <folder2> <etc.>
     git commit -m "Your message about the commit"
     git remote add origin https://github.com/yourUsername/yourRepository.git
     git push -u origin master
     git push origin master  

type

%matplotlib qt

when you want graphs in a separate window and

%matplotlib inline

when you want an inline plot

Unfortunately, there is not a direct way to do this with a single formula. However, there is a fairly simple workaround that exists.

On the Excel Ribbon, go to "Formulas" and click on "Name Manager". Select "New" and then enter "CellColor" as the "Name". Jump down to the "Refers to" part and enter the following:

=GET.CELL(63,OFFSET(INDIRECT("RC",FALSE),1,1))

Hit OK then close the "Name Manager" window.

Now, in cell A1 enter the following:

=IF(CellColor=3,"FQS",IF(CellColor=6,"SM",""))

This will return FQS for red and SM for yellow. For any other color the cell will remain blank.

***If the value in A1 doesn't update, hit 'F9' on your keyboard to force Excel to update the calculations at any point (or if the color in B2 ever changes).

Below is a reference for a list of cell fill colors (there are 56 available) if you ever want to expand things: http://www.smixe.com/excel-color-pallette.html

Cheers.

::Edit::

The formula used in Name Manager can be further simplified if it helps your understanding of how it works (the version that I included above is a lot more flexible and is easier to use in checking multiple cell references when copied around as it uses its own cell address as a reference point instead of specifically targeting cell B2).

Either way, if you'd like to simplify things, you can use this formula in Name Manager instead:

=GET.CELL(63,Sheet1!B2)

Spring Boot 2.2.2 / Gradle:

Gradle (build.gradle):

implementation("com.fasterxml.jackson.datatype:jackson-datatype-jsr310")

Entity (User.class):

LocalDate dateOfBirth;

Code:

ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JavaTimeModule());
User user = mapper.readValue(json, User.class);

Table names cannot be supplied as parameters, so you'll have to construct the SQL string manually like this:

SET @SQLQuery = 'SELECT * FROM ' + @TableName + ' WHERE EmployeeID = @EmpID' 

However, make sure that your application does not allow a user to directly enter the value of @TableName, as this would make your query susceptible to SQL injection. For one possible solution to this, see this answer.

You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.

CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace);  CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession);  CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context);       

There used to be a statement in the SQLite documentation that the practical size limit of a database file was a few dozen GB:s. That was mostly due to the need for SQLite to "allocate a bitmap of dirty pages" whenever you started a transaction. Thus 256 byte of RAM were required for each MB in the database. Inserting into a 50 GB DB-file would require a hefty (2^8)*(2^10)=2^18=256 MB of RAM.

But as of recent versions of SQLite, this is no longer needed. Read more here.

For Windows 8:

Control Panel -> (Search for) Credentials Manager -> Check Web Credentials

this worked for me...

The best way is to specify the format.

format(a, 'b')

returns the binary value of a in string format.

To convert a binary string back to integer, use int() function.

int('110', 2)

returns integer value of binary string.

Update on @ghostJago answer above

for me it worked as the following lines in VS2017

string curDir = Directory.GetCurrentDirectory();
this.webBrowser1.Navigate(new Uri(String.Format("file:///{0}/my_html.html", curDir)));

If you are using Linux environment then you can use the PHP's exec command to invoke the linux curl. Here is a sample code, which will make a Asynchronous HTTP post.

function _async_http_post($url, $json_string) {
  $run = "curl -X POST -H 'Content-Type: application/json'";
  $run.= " -d '" .$json_string. "' " . "'" . $url . "'";
  $run.= " > /dev/null 2>&1 &";
  exec($run, $output, $exit);
  return $exit == 0;
}

This code does not need any extra PHP libs and it can complete the http post in less than 10 milliseconds.

You might not have the ability to install Expect on the target server. This is often the case when one writes, say, a Jenkins job.

If so, I would consider something like the answer to the following on askubuntu.com:

https://askubuntu.com/questions/338857/automatically-enter-input-in-command-line

printf 'y\nyes\nno\nmaybe\n' | ./script_that_needs_user_input

Note that in some rare cases the command does not require the user to press enter after the character. in that case leave the newlines out:

printf 'yyy' | ./script_that_needs_user_input

For sake of completeness you can also use a here document:

./script_that_needs_user_input << EOF
y
y
y
EOF

Or if your shell supports it a here string:

./script <<< "y
y
y
"

Or you can create a file with one input per line:

./script < inputfile

Again, all credit for this answer goes to the author of the answer on askubuntu.com, lesmana.

50 Meg is the max for Cell data download.

But you might be able to keep it under that in the app store and then have the app download other content after the user install and runs the app, so the app can be bigger. But not sure what the apple rules are for this.

I know that all in-app purchases need to be approved, but not sure if this kind of content needs to be approved.

<form id="uploadbanner" enctype="multipart/form-data" method="post" action="#">
   <input id="fileupload" name="myfile" type="file" />
   <input type="submit" value="submit" id="submit" />
</form>

To upload a file, it is essential to set enctype="multipart/form-data" on your form

You need that form type and then some php to process the file :)

You should probably check out Uploadify if you want something very customisable out of the box.

Division is performed using the / operator:

result = a / b;

Modulo division is done using the % operator:

result = a % b;

The magic method __getitem__ is basically used for accessing list items, dictionary entries, array elements etc. It is very useful for a quick lookup of instance attributes.

Here I am showing this with an example class Person that can be instantiated by 'name', 'age', and 'dob' (date of birth). The __getitem__ method is written in a way that one can access the indexed instance attributes, such as first or last name, day, month or year of the dob, etc.

import copy

# Constants that can be used to index date of birth's Date-Month-Year
D = 0; M = 1; Y = -1

class Person(object):
    def __init__(self, name, age, dob):
        self.name = name
        self.age = age
        self.dob = dob

    def __getitem__(self, indx):
        print ("Calling __getitem__")
        p = copy.copy(self)

        p.name = p.name.split(" ")[indx]
        p.dob = p.dob[indx] # or, p.dob = p.dob.__getitem__(indx)
        return p

Suppose one user input is as follows:

p = Person(name = 'Jonab Gutu', age = 20, dob=(1, 1, 1999))

With the help of __getitem__ method, the user can access the indexed attributes. e.g.,

print p[0].name # print first (or last) name
print p[Y].dob  # print (Date or Month or ) Year of the 'date of birth'

write.csv([enter name of dataframe here],file = file.choose(new = T))

After running above script this window will open :

Type the new file name with extension in the File name field and click Open, it'll ask you to create a new file to which you should select Yes and the file will be created and saved in the desired location.

There are two main things on keeping a forked repository always update for good.

1. Create the branches from the fork master and do changes there.

So when your Pull Request is accepted then you can safely delete the branch as your contributed code will be then live in your master of your forked repository when you update it with the upstream. By this your master will always be in clean condition to create a new branch to do another change.

2. Create a scheduled job for the fork master to do update automatically.

This can be done with cron. Here is for an example code if you do it in linux.

$ crontab -e

put this code on the crontab file to execute the job in hourly basis.

0 * * * * sh ~/cron.sh

then create the cron.sh script file and a git interaction with ssh-agent and/or expect as below

#!/bin/sh
WORKDIR=/path/to/your/dir   
REPOSITORY=<name of your repo>
MASTER="[email protected]:<username>/$REPOSITORY.git"   
[email protected]:<upstream>/<name of the repo>.git  

cd $WORKDIR && rm -rf $REPOSITORY
eval `ssh-agent` && expect ~/.ssh/agent && ssh-add -l
git clone $MASTER && cd $REPOSITORY && git checkout master
git remote add upstream $UPSTREAM && git fetch --prune upstream
if [ `git rev-list HEAD...upstream/master --count` -eq 0 ]
then
    echo "all the same, do nothing"
else
    echo "update exist, do rebase!"
    git reset --hard upstream/master
    git push origin master --force
fi
cd $WORKDIR && rm -rf $REPOSITORY
eval `ssh-agent -k`

Check your forked repository. From time to time it will always show this notification:

This branch is even with <upstream>:master.

Alternatively you could also position the cursor onto the class name and press alt+enter (Show intention actions and quick fixes). It will suggest to Create Test.

At least works in IDEA version 12.

If you're a programmer who edits a lot of text, then it's important to learn an A Serious Text Editor. Which Serious Text Editor you learn is not terribly important and is largely dependent on the types of environments you expect to be editing in.

The reason is that these editors are highly optimized to perform the kinds of tasks that you will be doing a lot. For example, consider adding the same bit of text to the end of every line. This is trivial in A Serious Text Editor, but ridiculously cumbersome otherwise.

Usually vim's killer features are considered: A) that it's available on pretty much every Unix you'll ever encounter and B) your fingers very rarely have to leave the home row, which means you'll be able to edit text very, very quickly. It's also usually very fast and lightweight even when editing huge files.

There are plenty of alternatives, however. Emacs is the most common example, of course, and it's much more than just an advanced text editor if you really dig into it. I'm personally a very happy TextMate user now after years of using vim/gvim.

The trick to switching to any of these is to force yourself to use them the way they were intended. For example, in vim, if you're manually performing every step in a multi-step process or if you're using the arrow keys or the mouse then there's probably a better way to do it. Stop what you're doing and look it up.

If you do nothing else, learn the basic navigation controls for both vim and Emacs since they pop up all over the place. For example, you can use Emacs-style controls in any text input field in Mac OS, in most Unix shells, in Eclipse, etc. You can use vim-style controls in the less(1) command, on Slashdot, on gmail, etc.

Have fun!

Cookie is basically a global array accessed across web browsers. Many a times used to send/receive values. it acts as a storage mechanism to access values between forms. Cookies can be disabled by the browser which adds a constraint to their use in comparison to session.

Session can be defined as something between logging in and logging out. the time between the user logging in and logging out is a session. Session stores values only for the session time i.e before logging out. Sessions are used to track the activities of the user, once he logs on.

Today we use Bearer token more often that Basic Authentication but if you want to have Basic Authentication first to get Bearer token then there is a couple ways:

const request = new XMLHttpRequest();
request.open('GET', url, false, username,password)
request.onreadystatechange = function() {
        // D some business logics here if you receive return
   if(request.readyState === 4 && request.status === 200) {
       console.log(request.responseText);
   }
}
request.send()

Full syntax is here

Second Approach using Ajax:

$.ajax
({
  type: "GET",
  url: "abc.xyz",
  dataType: 'json',
  async: false,
  username: "username",
  password: "password",
  data: '{ "key":"sample" }',
  success: function (){
    alert('Thanks for your up vote!');
  }
});

Hopefully, this provides you a hint where to start API calls with JS. In Frameworks like Angular, React, etc there are more powerful ways to make API call with Basic Authentication or Oauth Authentication. Just explore it.

I found the following approach to be the most effective for sampling a DataFrame:

print(df[A:B]) ## 'A' and 'B' are the first and last records in range

For example, print(df[10:15]) will print rows 10 through 15 - inclusive - from your data set.

Maybe the "Output type" in properties->Application of the project must be a "Class Library" instead of console or windows application.

This one will also work

SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.dark);
SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.light);

when you do UNIQUE as a table level constraint as you have done then what your defining is a bit like a composite primary key see ddl constraints, here is an extract

"This specifies that the *combination* of values in the indicated columns is unique across the whole table, though any one of the columns need not be (and ordinarily isn't) unique."

this means that either field could possibly have a non unique value provided the combination is unique and this does not match your foreign key constraint.

most likely you want the constraint to be at column level. so rather then define them as table level constraints, 'append' UNIQUE to the end of the column definition like name VARCHAR(60) NOT NULL UNIQUE or specify indivdual table level constraints for each field.

I would like to make a addon for tiago's answer:

Suppose you're hiding element using ng-show and adding a required attribute on the same:

<div ng-show="false">
    <input required name="something" ng-model="name"/>
</div>

will throw an error something like :

An invalid form control with name='' is not focusable

This is because you just cannot impose required validation on hidden elements. Using ng-required makes it easier to conditionally apply required validation which is just awesome!!

Date#parse is deprecated . The alternative is :

java.text.DateFormat#parse 

thereFore :

 new SimpleDateFormat("E MMM dd H:m:s z yyyy", Locale.ARABIC).parse(testDate)

Note that SimpleDateFormat is an implementation of DateFormat

Newer versions of MongoDB support bulk operations:

var col = db.collection('people');
var batch = col.initializeUnorderedBulkOp();

batch.insert({name: "John"});
batch.insert({name: "Jane"});
batch.insert({name: "Jason"});
batch.insert({name: "Joanne"});

batch.execute(function(err, result) {
    if (err) console.error(err);
    console.log('Inserted ' + result.nInserted + ' row(s).');
}

Muppy is (yet another) Memory Usage Profiler for Python. The focus of this toolset is laid on the identification of memory leaks.

Muppy tries to help developers to identity memory leaks of Python applications. It enables the tracking of memory usage during runtime and the identification of objects which are leaking. Additionally, tools are provided which allow to locate the source of not released objects.

$start_date="17/02/2012";
$end_date="21/02/2012";
$date_from_user="19/02/2012";

function geraTimestamp($data)
{
    $partes = explode('/', $data); 
    return mktime(0, 0, 0, $partes[1], $partes[0], $partes[2]);
}


$startDatedt = geraTimestamp($start_date); 
$endDatedt = geraTimestamp($end_date);
$usrDatedt = geraTimestamp($date_from_user);

if (($usrDatedt >= $startDatedt) && ($usrDatedt <= $endDatedt))
{ 
    echo "Dentro";
}    
else
{
    echo "Fora";
}

You can do this with pure CSS but you will need to hard code the offset scroll amounts, which may not be ideal should you be changing page content- or should dimensions of your content change on say window resize.

You're likely best placed to use e.g. jQuery, specifically:

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

A complete implementation may be:

$('#up, #down').on('click', function(e){
    e.preventDefault();
    var target= $(this).get(0).id == 'up' ? $('#down') : $('#up');
    $('html, body').stop().animate({
       scrollTop: target.offset().top
    }, 1000);
});

Where element is the target element to scroll to and 1000 is the delay in ms before completion.

Demo Fiddle

The benefit being, no matter what changes to your content dimensions, the function will not need to be altered.

When you want to return a JSON response in MVC .Net Core You can also use:

Response.StatusCode = (int)HttpStatusCode.InternalServerError;//Equals to HTTPResponse 500
return Json(new { responseText = "my error" });

This will return both JSON result and HTTPStatus. I use it for returning results to jQuery.ajax().

This error happens due to the combined effect of two factors:

• The HTTP request, when complete, invokes either onResponse() or onError() (which work on the main thread) without knowing whether the Activity is still in the foreground or not. If the Activity is gone (the user navigated elsewhere), getActivity() returns null.
• The Volley Response is expressed as an anonymous inner class, which implicitly holds a strong reference to the outer Activity class. This results in a classic memory leak.

To solve this problem, you should always do:

Activity activity = getActivity();
if(activity != null){

    // etc ...

}

and also, use isAdded() in the onError() method as well:

@Override
public void onError(VolleyError error) {

    Activity activity = getActivity(); 
    if(activity != null && isAdded())
        mProgressDialog.setVisibility(View.GONE);
        if (error instanceof NoConnectionError) {
           String errormsg = getResources().getString(R.string.no_internet_error_msg);
           Toast.makeText(activity, errormsg, Toast.LENGTH_LONG).show();
        }
    }
}

UPDATE 2017:

In C++17 there is now an official way to list files of your file system: std::filesystem. There is an excellent answer from Shreevardhan below with this source code:

#include <string>
#include <iostream>
#include <filesystem>
namespace fs = std::filesystem;

int main()
{
    std::string path = "/path/to/directory";
    for (const auto & entry : fs::directory_iterator(path))
        std::cout << entry.path() << std::endl;
}

Old Answer:

In small and simple tasks I do not use boost, I use dirent.h which is also available for windows:

DIR *dir;
struct dirent *ent;
if ((dir = opendir ("c:\\src\\")) != NULL) {
  /* print all the files and directories within directory */
  while ((ent = readdir (dir)) != NULL) {
    printf ("%s\n", ent->d_name);
  }
  closedir (dir);
} else {
  /* could not open directory */
  perror ("");
  return EXIT_FAILURE;
}

It is just a small header file and does most of the simple stuff you need without using a big template-based approach like boost(no offence, I like boost!).

The author of the windows compatibility layer is Toni Ronkko. In Unix, it is a standard header.

I was facing this problem when I imported google-services.json file to implement Analytics. I already had global_tracker.xml file in the xml folder. During build, while merging contents from google-services.json file, the error was started occurring. For time being, the error is resolved after removing the goolgle-services.json file. And using the older Analytics solution.

Check the last XML or Json file that you edited/imported and maybe you will file error there. That's what helped in my case.

However, if you can reliably test your code to confirm that calling Collect() won't have a negative impact then go ahead...

IMHO, this is similar to saying "If you can prove that your program will never have any bugs in the future, then go ahead..."

In all seriousness, forcing the GC is useful for debugging/testing purposes. If you feel like you need to do it at any other times, then either you are mistaken, or your program has been built wrong. Either way, the solution is not forcing the GC...

Whenever possible, avoid applying functions to a column in the where clause:

SELECT *
  FROM table_name
 WHERE timestamp >= UNIX_TIMESTAMP('2010-10-01 00:00:00') 
   AND timestamp <  UNIX_TIMESTAMP('2010-11-01 00:00:00');

Applying a function to the timestamp column (e.g., FROM_UNIXTIME(timestamp) = ...) makes indexing much harder.

1) I have experienced same issue, my Xcode version was 7.0.1, and I updated my iPhone to version 9.2, then upon using Xcode, my iPhone was shown in the section of unavailable device. Just like in image below:

2) But then I somehow managed to select my iPhone by clicking at
Product -> Destination -> Unavailable Device

3) But that didn't solved my problem, and it started showing:

Could not find Developer Disk Image

Solution) Then finally I downloaded latest version of Xcode version 7.2 from here and everything has worked fine for me.

Update: Whenever version of iPhone device is higher than version of Xcode, you may experience same issue, so you should update your Xcode version to remove this error.

The problem is your "Project SDK" is none! Add a "Project SDK" by clicking "New ..." and choose the path of JDK. And then it should be OK.

Based on the Worker objects methods mentioned in other answers, I decided to see if I could expand on the solution to invoke more threads - in this case the optimal number the machine can run and spin up multiple workers with indeterminate completion times. To do this I still need to subclass QThread - but only to assign a thread number and to 'reimplement' the signals 'finished' and 'started' to include their thread number.

I've focused quite a bit on the signals between the main gui, the threads, and the workers.

Similarly, others answers have been a pains to point out not parenting the QThread but I don't think this is a real concern. However, my code also is careful to destroy the QThread objects.

However, I wasn't able to parent the worker objects so it seems desirable to send them the deleteLater() signal, either when the thread function is finished or the GUI is destroyed. I've had my own code hang for not doing this.

Another enhancement I felt was necessary was was reimplement the closeEvent of the GUI (QWidget) such that the threads would be instructed to quit and then the GUI would wait until all the threads were finished. When I played with some of the other answers to this question, I got QThread destroyed errors.

Perhaps it will be useful to others. I certainly found it a useful exercise. Perhaps others will know a better way for a thread to announce it identity.

@Michael Durrant's answer ably covers the shell itself, but the shell environment also includes the various commands you use in the shell and these are going to be similar -- but not identical -- between OS X and linux. In general, both will have the same core commands and features (especially those defined in the Posix standard), but a lot of extensions will be different.

For example, linux systems generally have a useradd command to create new users, but OS X doesn't. On OS X, you generally use the GUI to create users; if you need to create them from the command line, you use dscl (which linux doesn't have) to edit the user database (see here). (Update: starting in macOS High Sierra v10.13, you can use sysadminctl -addUser instead.)

Also, some commands they have in common will have different features and options. For example, linuxes generally include GNU sed, which uses the -r option to invoke extended regular expressions; on OS X, you'd use the -E option to get the same effect. Similarly, in linux you might use ls --color=auto to get colorized output; on macOS, the closest equivalent is ls -G.

EDIT: Another difference is that many linux commands allow options to be specified after their arguments (e.g. ls file1 file2 -l), while most OS X commands require options to come strictly first (ls -l file1 file2).

Finally, since the OS itself is different, some commands wind up behaving differently between the OSes. For example, on linux you'd probably use ifconfig to change your network configuration. On OS X, ifconfig will work (probably with slightly different syntax), but your changes are likely to be overwritten randomly by the system configuration daemon; instead you should edit the network preferences with networksetup, and then let the config daemon apply them to the live network state.

      5 => 'Mark As Spam',

First, Jonathan's point about vectorizing is correct. If your getWellID() function is vectorized, then you can skip the loop and just use cat or write.csv:

write.csv(data.frame(wellid=getWellID(well$name, well$plate), 
         value1=well$value1, value2=well$value2), file=outputFile)

If getWellID() isn't vectorized, then Jonathan's recommendation of using by or knguyen's suggestion of apply should work.

Otherwise, if you really want to use for, you can do something like this:

for(i in 1:nrow(dataFrame)) {
    row <- dataFrame[i,]
    # do stuff with row
}

You can also try to use the foreach package, although it requires you to become familiar with that syntax. Here's a simple example:

library(foreach)
d <- data.frame(x=1:10, y=rnorm(10))
s <- foreach(d=iter(d, by='row'), .combine=rbind) %dopar% d

A final option is to use a function out of the plyr package, in which case the convention will be very similar to the apply function.

library(plyr)
ddply(dataFrame, .(x), function(x) { # do stuff })

var myItem = myList.Find(item => item.property == "something");

@Elli's answer can work in FontAwesome 5, but it requires using the correct font name and using the specific CSS for the version you want. For example when using FA5 Free, I could not get it to work if I included the all.css, but it worked fine if I included the solid.css:

<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.8.1/css/solid.css">_x000D_
_x000D_
<input type="text" placeholder="&#xF002; Search" style="font-family: Arial, 'Font Awesome 5 Free'" />

For FA5 Pro the font name is 'Font Awesome 5 Pro'

Use .closest() with a selector:

var $div = $('#divid').closest('div[class^="div-a"]');

Don't use spaces, use &nbsp.

Use parentheses:

But you don't really want to do that with lists very often, since linked lists take time to traverse. If you want to index into a collection, use Vector (immutable) or ArrayBuffer (mutable) or possibly Array (which is just a Java array, except again you index into it with (i) instead of [i]).

Yes, you can! There's a Visual Studio for macs and there's Visual Studio Code if you only need a text editor like Sublime Text.

Class path entries can contain the basename wildcard character *, which is considered equivalent to specifying a list of all the files in the directory with the extension .jar or .JAR. For example, the class path entry foo/* specifies all JAR files in the directory named foo. A classpath entry consisting simply of * expands to a list of all the jar files in the current directory.

This should work in Java6, not sure about Java5

(If it seems it does not work as expected, try putting quotes. eg: "foo/*")

If it doesn't work in the latest version of reactjs, try using innerRef

class MyComponent extends React.Component {


  render() {
    return (
      <div onClick={this.handleClick}>
        <input innerRef={input => this.inputElement = input} />
      </div>
    );
  }

  handleClick = (e) => {
    this.inputElement.click();
  }
}

Hope helps someone.

Per @l3x, it depends.

There are clearly two sets of general situations where the correct answer can be different, along with a third which is not as general:

a) You are a user sending private mails:

Very few modern email systems implement case sensitivity, so you are probably fine to ignore case and choose whatever case you feel like using. There is no guarantee that all your mails will be delivered - but so few mails would be negatively affected that you should not worry about it.

b) You are developing mail software:

See RFC5321 2.4 excerpt at the bottom.

When you are developing mail software, you want to be RFC-compliant. You can make your own users' email addresses case insensitive if you want to (and you probably should). But in order to be RFC compliant, you MUST treat outside addresses as case sensitive.

c) Managing business-owned lists of email addresses as an employee:

It is possible that the same email recipient is added to a list more than once - but using different case. In this situation though the addresses are technically different, it might result in a recipient receiving duplicate emails. How you treat this situation is similar to situation a) in that you are probably fine to treat them as duplicates and to remove a duplicate entry. It is better to treat these as special cases however, by sending a "reminder" mail to both addresses to ask them if the case of the email address is accurate.

From a legal standpoint, if you remove a duplicate without acknowledgement/permission from both addresses, you can be held responsible for leaking private information/authentication to an unauthorised address simply because two actually-separate recipients have the same address with different cases.

Excerpt from RFC5321 2.4:

The local-part of a mailbox MUST BE treated as case sensitive. Therefore, SMTP implementations MUST take care to preserve the case of mailbox local-parts. In particular, for some hosts, the user "smith" is different from the user "Smith". However, exploiting the case sensitivity of mailbox local-parts impedes interoperability and is discouraged.

If you want to get source map file different version, you can use this link http://code.jquery.com/jquery-x.xx.x.min.map

Instead x.xx.x put your version number.

Note: Some links, which you get on this method, may be broken :)

You have to use image

.listStyle {
    list-style: none;
    background: url(bullet.jpg) no-repeat left center;
    padding-left: 40px;
}

at the end of your command put: | tac

tac does exactly what you're asking for, it "Write each FILE to standard output, last line first."

tac is the opposite of cat :-).

Have you looked at this page?

http://www.mongodb.org/display/DOCS/Aggregation#Aggregation-Distinct

That might save you some time?

eg db.addresses.distinct("zip-code");

Yeah, use .match, rather than .search. The result from the .match call will return the actual string that was matched itself, but it can still be used as a boolean value.

var string = "Stackoverflow is the BEST";
var result = string.match(/best/i);
// result == 'BEST';

if (result){
    alert('Matched');
}

Using a regular expression like that is probably the tidiest and most obvious way to do that in JavaScript, but bear in mind it is a regular expression, and thus can contain regex metacharacters. If you want to take the string from elsewhere (eg, user input), or if you want to avoid having to escape a lot of metacharacters, then you're probably best using indexOf like this:

matchString = 'best';
// If the match string is coming from user input you could do
// matchString = userInput.toLowerCase() here.

if (string.toLowerCase().indexOf(matchString) != -1){
    alert('Matched');
}

Unfortunately, the string.encode() method is not always reliable. Check out this thread for more information: What is the fool proof way to convert some string (utf-8 or else) to a simple ASCII string in python

First off, you'll want to go through Oracle's tutorial to learn how to do basic I/O in Java.

After that, you will want to look at the tutorial on how to use a file chooser.

You can use SRP to use secure passwords over an insecure channel. The advantage is that even if an attacker sniffs the traffic, or compromises the server, they can't use the passwords on a different server. https://github.com/alax/jsrp is a javascript library that supports secure passwords over HTTP in the browser, or server side (via node).

This one helped me:

Consider whether you really need all this data explicitly, or can the matrix be sparse? There is good support in R (see Matrix package for e.g.) for sparse matrices.

Keep all other processes and objects in R to a minimum when you need to make objects of this size. Use gc() to clear now unused memory, or, better only create the object you need in one session.

If the above cannot help, get a 64-bit machine with as much RAM as you can afford, and install 64-bit R.

If you cannot do that there are many online services for remote computing.

If you cannot do that the memory-mapping tools like package ff (or bigmemory as Sascha mentions) will help you build a new solution. In my limited experience ff is the more advanced package, but you should read the High Performance Computing topic on CRAN Task Views.

A few answers here have tried to explain the "screen" issue where top left is 0,0 and bottom right is (positive) screen width, screen height. Most grids have the Y axis as positive above X not below.

The following method will work with screen values instead of "grid" values. The only difference to the excepted answer is the Y values are inverted.

/**
 * Work out the angle from the x horizontal winding anti-clockwise 
 * in screen space. 
 * 
 * The value returned from the following should be 315. 
 * <pre>
 * x,y -------------
 *     |  1,1
 *     |    \
 *     |     \
 *     |     2,2
 * </pre>
 * @param p1
 * @param p2
 * @return - a double from 0 to 360
 */
public static double angleOf(PointF p1, PointF p2) {
    // NOTE: Remember that most math has the Y axis as positive above the X.
    // However, for screens we have Y as positive below. For this reason, 
    // the Y values are inverted to get the expected results.
    final double deltaY = (p1.y - p2.y);
    final double deltaX = (p2.x - p1.x);
    final double result = Math.toDegrees(Math.atan2(deltaY, deltaX)); 
    return (result < 0) ? (360d + result) : result;
}

Two things are happening here.

1. You are not using the container class properly.
2. You are trying to override Bootstrap's CSS for the container class

Bootstrap uses a grid system and the .container class is defined in its own CSS. The grid has to exist within a container class DIV. The container DIV is just an indication to Bootstrap that the grid within has that parent. Therefore, you cannot set the height of a container.

What you want to do is the following:

<div class="container-fluid"> <!-- this is to make it responsive to your screen width -->
    <div class="row">
        <div class="col-md-4 myClassName">  <!-- myClassName is defined in my CSS as you defined your container -->
            <img src="#.jpg" height="200px" width="300px">
        </div>
    </div>
</div>

Here you can find more info on the Bootstrap grid system.

That being said, if you absolutely MUST override the Bootstrap CSS then I would try using the "!important" clause to my CSS definition as such...

.container {
   padding-right: 15px;
   padding-left: 15px;
   margin-right: auto;
   margin-left: auto;
   max-width: 900px;
   overflow:hidden;
   min-height:0px !important;
}

But I have always found that the "!important" clause just makes for messy CSS.

I have written a small module to do just that, called timexe:

• Its simple,small reliable code and has no dependencies
• Resolution is in milliseconds and has high precision over time
• Cron like, but not compatible (reversed order and other Improvements)
• I works in the browser too

Install:

npm install timexe

use:

var timexe = require('timexe');
//Every 30 sec
var res1=timexe(”* * * * * /30”, function() console.log(“Its time again”)});

//Every minute
var res2=timexe(”* * * * *”,function() console.log(“a minute has passed”)});

//Every 7 days
var res3=timexe(”* y/7”,function() console.log(“its the 7th day”)});

//Every Wednesdays 
var res3=timexe(”* * w3”,function() console.log(“its Wednesdays”)});

// Stop "every 30 sec. timer"
timexe.remove(res1.id);

you can achieve start/stop functionality by removing/re-adding the entry directly in the timexe job array. But its not an express function.

Here is my take on that one...

function copy(text) {
    var input = document.createElement('input');
    input.setAttribute('value', text);
    document.body.appendChild(input);
    input.select();
    var result = document.execCommand('copy');
    document.body.removeChild(input);
    return result;
 }

@korayem: Note that using html input field won't respect line breaks \n and will flatten any text into a single line.

As mentioned by @nikksan in the comments, using textarea will fix the problem as follows:

function copy(text) {
    var input = document.createElement('textarea');
    input.innerHTML = text;
    document.body.appendChild(input);
    input.select();
    var result = document.execCommand('copy');
    document.body.removeChild(input);
    return result;
}

I usually put these lines at the beginning of my stored procedure, and then at the end.

It is an "exists" check for #temp tables.

IF OBJECT_ID('tempdb..#MyCoolTempTable') IS NOT NULL
begin
        drop table #MyCoolTempTable
end

Full Example:

CREATE PROCEDURE [dbo].[uspTempTableSuperSafeExample]
AS
BEGIN
    SET NOCOUNT ON;


    IF OBJECT_ID('tempdb..#MyCoolTempTable') IS NOT NULL
    BEGIN
            DROP TABLE #MyCoolTempTable
    END


    CREATE TABLE #MyCoolTempTable (
        MyCoolTempTableKey INT IDENTITY(1,1),
        MyValue VARCHAR(128)
    )  

    INSERT INTO #MyCoolTempTable (MyValue)
        SELECT LEFT(@@VERSION, 128)
        UNION ALL SELECT TOP 10 LEFT(name, 128) from sysobjects

    SELECT MyCoolTempTableKey, MyValue FROM #MyCoolTempTable


    IF OBJECT_ID('tempdb..#MyCoolTempTable') IS NOT NULL
    BEGIN
            DROP TABLE #MyCoolTempTable
    END


    SET NOCOUNT OFF;
END
GO

In my case I wanted to compare values in cells of column E with Cells in Column G

Highlight the selection of cells to be checked in column E.

Select Conditional Format: Highlight cell rules Select one of the choices in my case it was greater than. In the left hand field of pop up use =indirect("g"&row()) where g was the row I was comparing against.

Now the row you are formatting will highlight based on if it is greater than the selection in row G

This works for every cell in Column E compared to cell in Column G of the selection you made for column E.

If G2 is greater than E2 it formats

G3 is greater than E3 it formats etc

You may want to use the jasypt library (Java Simplified Encryption), which is quite easy to use. ( Also, it's recommended to check against the encrypted password rather than decrypting the encrypted password )

To use jasypt, if you're using maven, you can include jasypt into your pom.xml file as follows:

<dependency>
    <groupId>org.jasypt</groupId>
    <artifactId>jasypt</artifactId>
    <version>1.9.3</version>
    <scope>compile</scope>

And then to encrypt the password, you can use StrongPasswordEncryptor

public static String encryptPassword(String inputPassword) {
    StrongPasswordEncryptor encryptor = new StrongPasswordEncryptor();
    return encryptor.encryptPassword(inputPassword);
}

Note: the encrypted password is different every time you call encryptPassword but the checkPassword method can still check that the unencrypted password still matches each of the encrypted passwords.

And to check the unencrypted password against the encrypted password, you can use the checkPassword method:

public static boolean checkPassword(String inputPassword, String encryptedStoredPassword) {
    StrongPasswordEncryptor encryptor = new StrongPasswordEncryptor();
    return encryptor.checkPassword(inputPassword, encryptedStoredPassword);
}

The page below provides detailed information on the complexities involved in creating safe encrypted passwords.

This is ridiculous but I just have rebooted my machine (mac) and the problem was gone like it has never happened. I hate to sound like a support guy...

Most of the above solutions are not mobile friendly.

The solution I am proposing detects if its not touch device and that the navbar-toggle (hamburger menu) is not visible and makes the parent menu item revealing submenu on hover and and follow its link on click

Also makes tne margin-top 0 because the gap between the navbar and the menu in some browser will not let you hover to the subitems

$(function(){_x000D_
    function is_touch_device() {_x000D_
        return 'ontouchstart' in window        // works on most browsers _x000D_
        || navigator.maxTouchPoints;       // works on IE10/11 and Surface_x000D_
    };_x000D_
_x000D_
    if(!is_touch_device() && $('.navbar-toggle:hidden')){_x000D_
      $('.dropdown-menu', this).css('margin-top',0);_x000D_
      $('.dropdown').hover(function(){ _x000D_

      });   _x000D_

Apparently thanks to since this pull request: https://github.com/remy/nodemon/pull/1552

Try it:

def showDf(df, count=None, percent=None, maxColumns=0):
    if (df == None): return
    import pandas
    from IPython.display import display
    pandas.set_option('display.encoding', 'UTF-8')
    # Pandas dataframe
    dfp = None
    # maxColumns param
    if (maxColumns >= 0):
        if (maxColumns == 0): maxColumns = len(df.columns)
        pandas.set_option('display.max_columns', maxColumns)
    # count param
    if (count == None and percent == None): count = 10 # Default count
    if (count != None):
        count = int(count)
        if (count == 0): count = df.count()
        pandas.set_option('display.max_rows', count)
        dfp = pandas.DataFrame(df.head(count), columns=df.columns)
        display(dfp)
    # percent param
    elif (percent != None):
        percent = float(percent)
        if (percent >=0.0 and percent <= 1.0):
            import datetime
            now = datetime.datetime.now()
            seed = long(now.strftime("%H%M%S"))
            dfs = df.sample(False, percent, seed)
            count = df.count()
            pandas.set_option('display.max_rows', count)
            dfp = dfs.toPandas()    
            display(dfp)

Examples of usages are:

# Shows the ten first rows of the Spark dataframe
showDf(df)
showDf(df, 10)
showDf(df, count=10)

# Shows a random sample which represents 15% of the Spark dataframe
showDf(df, percent=0.15)

06/2013 :

• This is a bug from Facebook, not your code
• Facebook will NOT fix this bug, they say it is "by design" that they broke the Android share system : https://developers.facebook.com/bugs/332619626816423
• use the SDK or share only URL.
• Tips: you could cheat a little using the web page title as text for the post.

There are many ways to achieve this, like flatten-and-filter or simply enumerate, but I think using Boolean/mask array is the easiest one (and iirc a much faster one):

>>> y = np.array([[123,24123,32432], [234,24,23]])
array([[  123, 24123, 32432],
       [  234,    24,    23]])
>>> b = y > 200
>>> b
array([[False,  True,  True],
       [ True, False, False]], dtype=bool)
>>> y[b]
array([24123, 32432,   234])
>>> len(y[b])
3
>>>> y[b].sum()
56789

Update:

As nneonneo has answered, if all you want is the number of elements that passes threshold, you can simply do:

>>>> (y>200).sum()
3

which is a simpler solution.

Speed comparison with filter:

### use boolean/mask array ###

b = y > 200

%timeit y[b]
100000 loops, best of 3: 3.31 us per loop

%timeit y[y>200]
100000 loops, best of 3: 7.57 us per loop

### use filter ###

x = y.ravel()
%timeit filter(lambda x:x>200, x)
100000 loops, best of 3: 9.33 us per loop

%timeit np.array(filter(lambda x:x>200, x))
10000 loops, best of 3: 21.7 us per loop

%timeit filter(lambda x:x>200, y.ravel())
100000 loops, best of 3: 11.2 us per loop

%timeit np.array(filter(lambda x:x>200, y.ravel()))
10000 loops, best of 3: 22.9 us per loop

*** use numpy.where ***

nb = np.where(y>200)
%timeit y[nb]
100000 loops, best of 3: 2.42 us per loop

%timeit y[np.where(y>200)]
100000 loops, best of 3: 10.3 us per loop

A wild idea, try parsing it and catch the exception:

import org.json.*;

public boolean isJSONValid(String test) {
    try {
        new JSONObject(test);
    } catch (JSONException ex) {
        // edited, to include @Arthur's comment
        // e.g. in case JSONArray is valid as well...
        try {
            new JSONArray(test);
        } catch (JSONException ex1) {
            return false;
        }
    }
    return true;
}

This code uses org.json JSON API implementation that is available on github, in maven and partially on Android.

Stopping the Storyboard can be done in the code behind, or the xaml, depending on where the need comes from.

If the EventTrigger is moved outside of the button, then we can go ahead and target it with another EventTrigger that will tell the storyboard to stop. When the storyboard is stopped in this manner it will not revert to the previous value.

Here I've moved the Button.Click EventTrigger to a surrounding StackPanel and added a new EventTrigger on the the CheckBox.Click to stop the Button's storyboard when the CheckBox is clicked. This lets us check and uncheck the CheckBox when it is clicked on and gives us the desired unchecking behavior from the button as well.

    <StackPanel x:Name="myStackPanel">

        <CheckBox x:Name="myCheckBox"
                  Content="My CheckBox" />

        <Button Content="Click to Uncheck"
                x:Name="myUncheckButton" />

        <Button Content="Click to check the box in code."
                Click="OnClick" />

        <StackPanel.Triggers>

            <EventTrigger RoutedEvent="Button.Click"
                          SourceName="myUncheckButton">
                <EventTrigger.Actions>
                    <BeginStoryboard x:Name="myBeginStoryboard">
                        <Storyboard x:Name="myStoryboard">
                            <BooleanAnimationUsingKeyFrames Storyboard.TargetName="myCheckBox"
                                                            Storyboard.TargetProperty="IsChecked">
                                <DiscreteBooleanKeyFrame KeyTime="00:00:00"
                                                         Value="False" />
                            </BooleanAnimationUsingKeyFrames>
                        </Storyboard>
                    </BeginStoryboard>
                </EventTrigger.Actions>
            </EventTrigger>

            <EventTrigger RoutedEvent="CheckBox.Click"
                          SourceName="myCheckBox">
                <EventTrigger.Actions>
                    <StopStoryboard BeginStoryboardName="myBeginStoryboard" />
                </EventTrigger.Actions>
            </EventTrigger>

        </StackPanel.Triggers>
    </StackPanel>

To stop the storyboard in the code behind, we will have to do something slightly different. The third button provides the method where we will stop the storyboard and set the IsChecked property back to true through code.

We can't call myStoryboard.Stop() because we did not begin the Storyboard through the code setting the isControllable parameter. Instead, we can remove the Storyboard. To do this we need the FrameworkElement that the storyboard exists on, in this case our StackPanel. Once the storyboard is removed, we can once again set the IsChecked property with it persisting to the UI.

    private void OnClick(object sender, RoutedEventArgs e)
    {
        myStoryboard.Remove(myStackPanel);
        myCheckBox.IsChecked = true;
    }

Let me try to answer in few words.

Hadoop is an eco-system which comprises of all other tools. So, you can't compare Hadoop but you can compare MapReduce.

Here are my few cents:

1. Hive: If your need is very SQLish meaning your problem statement can be catered by SQL, then the easiest thing to do would be to use Hive. The other case, when you would use hive is when you want a server to have certain structure of data.
2. Pig: If you are comfortable with Pig Latin and you need is more of the data pipelines. Also, your data lacks structure. In those cases, you could use Pig. Honestly there is not much difference between Hive & Pig with respect to the use cases.
3. MapReduce: If your problem can not be solved by using SQL straight, you first should try to create UDF for Hive & Pig and then if the UDF is not solving the problem then getting it done via MapReduce makes sense.

dict.iteritems is gone in Python3.x So use iter(dict.items()) to get the same output and memory alocation

To make @NotNull active you need Lombok:

https://projectlombok.org/features/NonNull

import lombok.NonNull;

Follow: Which @NotNull Java annotation should I use?

values_of_objArray = [
  { id: 3432, name: "Recent" },
  { id: 3442, name: "Most Popular" },
  { id: 3352, name: "Rating" }
];

private ValueId : number = 0 // this will be used for multi access like 
                             // update, deleting the obj with id.
private selectedObj : any;

private selectedValueObj(id: any) {
  this.ValueId = (id.srcElement || id.target).value;
  for (let i = 0; i < this.values_of_objArray.length; i++) {
    if (this.values_of_objArray[i].id == this.ValueId) {
      this.selectedObj = this.values_of_objArray[i];
    }
  }
}

Now play with this.selectedObj which has the selected obj from the view.

HTML:

<select name="values_of_obj" class="form-control" [(ngModel)]="ValueId"  
        (change)="selectedValueObj($event)" required>

  <option *ngFor="let Value of values_of_objArray"
          [value]="Value.id">{{Value.name}}</option>    
</select>

for(int a=0;a<myArray.size();a++){
        for(int b=a+1;b<myArray.size();b++){
            if(myArray.get(a).equalsIgnoreCase(myArray.get(b))){
                myArray.remove(b); 
                dups++;
                b--;
            }
        }
}

I managed to stop by adding those 2 lines

log4j.logger.org.hibernate.orm.deprecation=error

One obvious advantage of artificial neural networks over support vector machines is that artificial neural networks may have any number of outputs, while support vector machines have only one. The most direct way to create an n-ary classifier with support vector machines is to create n support vector machines and train each of them one by one. On the other hand, an n-ary classifier with neural networks can be trained in one go. Additionally, the neural network will make more sense because it is one whole, whereas the support vector machines are isolated systems. This is especially useful if the outputs are inter-related.

For example, if the goal was to classify hand-written digits, ten support vector machines would do. Each support vector machine would recognize exactly one digit, and fail to recognize all others. Since each handwritten digit cannot be meant to hold more information than just its class, it makes no sense to try to solve this with an artificial neural network.

However, suppose the goal was to model a person's hormone balance (for several hormones) as a function of easily measured physiological factors such as time since last meal, heart rate, etc ... Since these factors are all inter-related, artificial neural network regression makes more sense than support vector machine regression.

A list is a chain of spaces that can be indexed by (0, 1, 2 .... etc). So if players was a list, players[0] or players[1] would have worked. If players is a dictionary, players["name"] would have worked.

Since this is very common question I have prepared some screen shots from Visual Studio to make it easy to follow in 4 simple steps.

For Portable apps change

package.json

as follows

"scripts": {
    "start": "node node_modules/.bin/react-scripts start",
    "build": "node node_modules/.bin/react-scripts build",
    "test": "node node_modules/.bin/react-scripts test",
    "eject": "node node_modules/.bin/react-scripts eject"
  }

This is probably unpopular way. But here how I do it:

object1 = // object to copy

YourClass *object2 = [[YourClass alloc] init];
object2.property1 = object1.property1;
object2.property2 = object1.property2;
..
etc.

Quite simple and straight forward. :P

If you are generally doing updates I would ..

1. Begin a transaction
2. Do the update
3. Check the rowcount
4. If it is 0 do the insert
5. Commit

If you are generally doing inserts I would

1. Begin a transaction
2. Try an insert
3. Check for primary key violation error
4. if we got an error do the update
5. Commit

This way you avoid the select and you are transactionally sound on Sqlite.

Try with this:

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Add respective layout
        setContentView(R.layout.main_activity);

        // Use package name which we want to check
        boolean isAppInstalled = appInstalledOrNot("com.check.application");  

        if(isAppInstalled) {
            //This intent will help you to launch if the package is already installed
            Intent LaunchIntent = getPackageManager()
                .getLaunchIntentForPackage("com.check.application");
            startActivity(LaunchIntent);

            Log.i("Application is already installed.");       
        } else {
            // Do whatever we want to do if application not installed
            // For example, Redirect to play store

            Log.i("Application is not currently installed.");
        }
    }

    private boolean appInstalledOrNot(String uri) {
        PackageManager pm = getPackageManager();
        try {
            pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
            return true;
        } catch (PackageManager.NameNotFoundException e) {
        }

        return false;
    }

}

If you use first answer, there is a problem with thumb. In chrome if you want the thumb to be larger than the track, then the box shadow overlaps the track with the height of the thumb.

Just sumup all these answers and wrote normally working slider with larger slider thumb: jsfiddle

const slider = document.getElementById("myinput")
const min = slider.min
const max = slider.max
const value = slider.value

slider.style.background = `linear-gradient(to right, red 0%, red ${(value-min)/(max-min)*100}%, #DEE2E6 ${(value-min)/(max-min)*100}%, #DEE2E6 100%)`

slider.oninput = function() {
  this.style.background = `linear-gradient(to right, red 0%, red ${(this.value-this.min)/(this.max-this.min)*100}%, #DEE2E6 ${(this.value-this.min)/(this.max-this.min)*100}%, #DEE2E6 100%)`
};

#myinput {
  border-radius: 8px;
  height: 4px;
  width: 150px;
  outline: none;
  -webkit-appearance: none;
}

input[type='range']::-webkit-slider-thumb {
  width: 6px;
  -webkit-appearance: none;
  height: 12px;
  background: black;
  border-radius: 2px;
}

<div class="chrome">
  <input id="myinput" type="range" min="0" value="25" max="200" />
</div>

This could also be an issue of building the code using a 64 bit configuration. You can try to select x86 as the build platform which can solve this issue. To do this right-click the solution and select Configuration Manager From there you can change the Platform of the project using the 32-bit .dll to x86

With the unobtrusive way:

• You don't have to call the validate() method.
• You specify requirements using data attributes (data-val, data-val-required, etc.)

Jquery Validate Example:

<input type="text" name="email" class="required">
<script>
        $(function () {
            $("form").validate();
        });
</script>

Jquery Validate Unobtrusive Example:

<input type="text" name="email" data-val="true" 
data-val-required="This field is required.">  

<div class="validation-summary-valid" data-valmsg-summary="true">
    <ul><li style="display:none"></li></ul>

When you run your application this way, the java excecutable read the MANIFEST inside your jar and find the main class you defined. In this class you have a static method called main. In this method you may use the command line arguments.

The ant solution above is easiest to configure, but I have had luck using the maven-upload-plugin from Atlassian. I was unable to find good documentation, here is how I use it:

<build>
  <plugin>
    <groupId>com.atlassian.maven.plugins</groupId>
    <artifactId>maven-upload-plugin</artifactId>
    <version>1.1</version>
    <configuration>
       <resourceSrc>
             ${project.build.directory}/${project.build.finalName}.${project.packaging}
       </resourceSrc>
       <resourceDest>${jboss.deployDir}</resourceDest>
       <serverId>${jboss.host}</serverId>
       <url>${jboss.deployUrl}</url>
     </configuration>
  </plugin>
</build>

The variables like "${jboss.host}" referenced above are defined in my ~/.m2/settings.xml and are activated using maven profiles. This solution is not constrained to JBoss, this is just what I named my variables. I have a profile for dev, test, and live. So to upload my ear to a jboss instance in test environment I would execute:

mvn upload:upload -P test

Here is a snipet from settings.xml:

<server>
  <id>localhost</id>
  <username>username</username>
  <password>{Pz+6YRsDJ8dUJD7XE8=} an encrypted password. Supported since maven 2.1</password>
</server>
...
<profiles>
  <profile>
    <id>dev</id>
    <properties>
      <jboss.host>localhost</jboss.host> 
      <jboss.deployDir>/opt/jboss/server/default/deploy/</jboss.deployDir>
      <jboss.deployUrl>scp://root@localhost</jboss.deployUrl>
    </properties>
  </profile>
  <profile>
    <id>test</id>
    <properties>
       <jboss.host>testserver</jboss.host>
       ...

Notes: The Atlassian maven repo that has this plugin is here: https://maven.atlassian.com/public/

I recommend downloading the sources and looking at the documentation inside to see all the features the plugin provides.

just using vanilla js

_x000D_
JSON.stringify(a) === JSON.stringify(b);_x000D_
// false_x000D_
b.prop2 = { prop3: 2};_x000D_
_x000D_
JSON.stringify(a) === JSON.stringify(b);_x000D_
// true

It's in the python docs.

import datetime
datetime.datetime.combine(datetime.date(2011, 1, 1), 
                          datetime.time(10, 23))

returns

datetime.datetime(2011, 1, 1, 10, 23)

Listview so have inbuild scrolling capabilities. So you can not use listview inside scrollview. Encapsulate it in any other layout like LinearLayout or RelativeLayout.

Run this in SSMS, it shows how line breaks in the SQL itself become part of string values that span lines :

PRINT 'Line 1
Line 2
Line 3'
PRINT ''

PRINT 'How long is a blank line feed?'
PRINT LEN('
')
PRINT ''

PRINT 'What are the ASCII values?'
PRINT ASCII(SUBSTRING('
',1,1))
PRINT ASCII(SUBSTRING('
',2,1))

Result :
Line 1
Line 2
Line 3

How long is a blank line feed?
2

What are the ASCII values?
13
10

Or if you'd rather specify your string on one line (almost!) you could employ REPLACE() like this (optionally use CHAR(13)+CHAR(10) as the replacement) :

PRINT REPLACE('Line 1`Line 2`Line 3','`','
')

For MacOS users:

Just do this and easily it will solve your problem:

brew install cocoapods

This one worked for me:

PGPASSWORD=postgres psql -h localhost -p 3307 -U postgres -d postgres

Use the above to load an initial script as:

PGPASSWORD=postgres psql -h localhost -p 3307 -U postgres -d postgres < src/sql/local/blabla.sql

Do not that i remap my ports as:

docker run -p3307:5432 --name postgres -e POSTGRES_PASSWORD=postgres -d postgres

Convert your x-axis data from text to datetime.datetime, use datetime.strptime:

>>> from datetime import datetime
>>> datetime.strptime("2012-may-31 19:00", "%Y-%b-%d %H:%M")
 datetime.datetime(2012, 5, 31, 19, 0)

This is an example of how to plot data once you have an array of datetimes:

import matplotlib.pyplot as plt
import datetime
import numpy as np

x = np.array([datetime.datetime(2013, 9, 28, i, 0) for i in range(24)])
y = np.random.randint(100, size=x.shape)

plt.plot(x,y)
plt.show()

In a nutshell it means.. You are trying to access an object without instantiating it.. You might need to use the "new" keyword to instantiate it first i.e create an instance of it.

For eg:

public class MyClass
{
   public int Id {get; set;}
}

MyClass myClass;

myClass.Id = 0; <----------- An error will be thrown here.. because myClass is null here...

You will have to use:

myClass = new MyClass();
myClass.Id = 0;

Hope I made it clear..

• In my case the issue is occurred because of am trying to open/show dialog box in onPostExecute AsyncTask

• However its an wrong method of showing dialog or Ui changes in onPostExecute.

• For that, we need to check the activity is in active Eg : !isFinishing() , if the activity is not finished then only able to show our dialog box or ui change.

  @Override
  protected void onPostExecute(String response_str) {
  
     getActivity().runOnUiThread(new Runnable() {
                  @Override
                  public void run() {
                      if (!((Activity) mContext).isFinishing()) {
                          try {
                              ShowAgilDialog();
                          } catch (WindowManager.BadTokenException e) {
                              Log.e("WindowManagerBad ", e.toString());
                          }
                      }
                  }
              });
  }
  

Try using the type attribute selector to find buttons (maybe this'll fix it too):

input[type=button]
{
  background-color: #E3E1B8; 
}

input[type=button]:hover
{
  background-color: #46000D
}

I've had the same issue. When I was clicking on item's toggle button in my recyclerView checked Toggle button appeared in every 10th item (for example if it was clicked in item with 0 index, items with 9, 18, 27 indexes were getting clicked too). Firstly, my code in onBindViewHolder was:

if (newsItems.get(position).getBookmark() == 1) {
            holder.getToggleButtonBookmark().setChecked(true);
        }

But then I added Else statement

if (newsItems.get(position).getBookmark() == 1) {
            holder.getToggleButtonBookmark().setChecked(true);
//else statement prevents auto toggling
        } else{
            holder.getToggleButtonBookmark().setChecked(false);
        }

And the problem was solved

SearchDialog or SearchWidget ?

When it comes to implement a search functionality there are two suggested approach by official Android Developer Documentation.
You can either use a SearchDialog or a SearchWidget.
I am going to explain the implementation of Search functionality using SearchWidget.

How to do it with Search widget ?

I will explain search functionality in a RecyclerView using SearchWidget. It's pretty straightforward.

Just follow these 5 Simple steps

1) Add searchView item in the menu

You can add SearchView can be added as actionView in menu using

app:useActionClass = "android.support.v7.widget.SearchView" .

<menu xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:app="http://schemas.android.com/apk/res-auto"
   xmlns:tools="http://schemas.android.com/tools"
   tools:context="rohksin.com.searchviewdemo.MainActivity">
   <item
       android:id="@+id/searchBar"
       app:showAsAction="always"
       app:actionViewClass="android.support.v7.widget.SearchView"
   />
</menu>

2) Set up SerchView Hint text, listener etc

You should initialize SearchView in the onCreateOptionsMenu(Menu menu) method.

  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
     // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);

        MenuItem searchItem = menu.findItem(R.id.searchBar);

        SearchView searchView = (SearchView) searchItem.getActionView();
        searchView.setQueryHint("Search People");
        searchView.setOnQueryTextListener(this);
        searchView.setIconified(false);

        return true;
   }

3) Implement SearchView.OnQueryTextListener in your Activity

OnQueryTextListener has two abstract methods

1. onQueryTextSubmit(String query)
2. onQueryTextChange(String newText

So your Activity skeleton would look like this

YourActivity extends AppCompatActivity implements SearchView.OnQueryTextListener{

     public boolean onQueryTextSubmit(String query)

     public boolean onQueryTextChange(String newText) 

}

4) Implement SearchView.OnQueryTextListener

You can provide the implementation for the abstract methods like this

public boolean onQueryTextSubmit(String query) {

    // This method can be used when a query is submitted eg. creating search history using SQLite DB

    Toast.makeText(this, "Query Inserted", Toast.LENGTH_SHORT).show();
    return true;
}

@Override
public boolean onQueryTextChange(String newText) {

    adapter.filter(newText);
    return true;
}

5) Write a filter method in your RecyclerView Adapter.

Most important part. You can write your own logic to perform search.
Here is mine. This snippet shows the list of Name which contains the text typed in the SearchView

public void filter(String queryText)
{
    list.clear();

    if(queryText.isEmpty())
    {
       list.addAll(copyList);
    }
    else
    {

       for(String name: copyList)
       {
           if(name.toLowerCase().contains(queryText.toLowerCase()))
           {
              list.add(name);
           }
       }

    }

   notifyDataSetChanged();
}

This isn't exactly what you are looking for but here is how I've approached this problem in the past;

You can enter a formula like;

=COUNTIF(A1:A10,"Green")

...into a cell. This will count the Number of cells between A1 and A10 that contain the text "Green". You can then select this cell value in a VBA Macro and assign it to a variable as normal.
