Here's a function that counts number of words in an HTML code:

$(this).val()
    .replace(/((&nbsp;)|(<[^>]*>))+/g, '') // remove html spaces and tags
    .replace(/\s+/g, ' ') // merge multiple spaces into one
    .trim() // trim ending and beginning spaces (yes, this is needed)
    .match(/\s/g) // find all spaces by regex
    .length // get amount of matches

I don't think it is possible to share a database link between more than one user but not all. They are either private (for one user only) or public (for all users).

A good way around this is to create a view in SCHEMA_B that exposes the table you want to access through the database link. This will also give you good control over who is allowed to select from the database link, as you can control the access to the view.

Do like this:

create database link db_link... as before;
create view mytable_view as select * from mytable@db_link;
grant select on mytable_view to myuser;

As of pandas 1.0.0, you no longer need to use numpy to create null values in your dataframe. Instead you can just use pandas.NA (which is of type pandas._libs.missing.NAType), so it will be treated as null within the dataframe but will not be null outside dataframe context.

There's simpler solution for that - set fixed height of card elements - header and body. This way, we can set resposive layout with standard boostrap column grid.

Here is my example: http://codeply.com/go/RHDawRSBol

 <div class="card-deck text-center">
    <div class="col-sm-6 col-md-4 col-lg-3">
        <div class="card mb-4">
            <img class="card-img-top img-fluid" src="//placehold.it/500x280" alt="Card image cap">
            <div class="card-body" style="height: 20rem">
                <h4 class="card-title">1 Card title</h4>
                <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
                <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
            </div>
        </div>

You can use the following:

return Redirect::back()->withInput(Input::all());

If you're using Form Request Validation, this is exactly how Laravel will redirect you back with errors and the given input.

Excerpt from \Illuminate\Foundation\Validation\ValidatesRequests:

return redirect()->to($this->getRedirectUrl())
                    ->withInput($request->input())
                    ->withErrors($errors, $this->errorBag());

Right-click on your project and choose Maven > Update Snapshots. In addition to that you can set "update Maven projects on startup" in Window > Preferences > Maven

UPDATE: In latest versions of Eclipse: Maven > Update Project. Make sure "Force Update of Snapshots/Releases" is checked.

The simple way is to create table as textfile and move the file to the appropriate location

CREATE EXTERNAL TABLE mytable(col1 string, col2 string)
row format delimited fields terminated by '|' stored as textfile;

Copy the file to the HDFS Location where table is created.
Hope this helps!!!

If you use anaconda navigator on windows, you can go too enviornments and scroll over the enviornments, the root enviorment will indicate where it is installed. It can help if you want to use this enviorment when you need to connect this to other applications, where you want to integrate some python code.

This should do the job

//get a reference to the canvas
var ctx = $('#canvas')[0].getContext("2d");

//draw a dot
ctx.beginPath();
ctx.arc(20, 20, 10, 0, Math.PI*2, true);
ctx.closePath();
ctx.fill();

A particularly interesting case is when you compare

   java.util.Arrays$ArrayList<[[name,value,type], [name1,value1,type1]]> 

and

   java.util.Collections$UnmodifiableCollection<[[name,value,type], [name1,value1,type1]]>

So far, the only solution I see is to change both of them into sets

assertEquals(new HashSet<CustomAttribute>(customAttributes), new HashSet<CustomAttribute>(result.getCustomAttributes()));

Or I could compare them element by element.

$text = "Cats chase mice";
$filename = "somefile.txt";
$fh = fopen($filename, "a");
fwrite($fh, $text);
fclose($fh);

You use fwrite()

The SciPy webpage used to provide build and installation instructions, but the instructions there now rely on OS binary distributions. To build SciPy (and NumPy) on operating systems without precompiled packages of the required libraries, you must build and then statically link to the Fortran libraries BLAS and LAPACK:

mkdir -p ~/src/
cd ~/src/
wget http://www.netlib.org/blas/blas.tgz
tar xzf blas.tgz
cd BLAS-*

## NOTE: The selected Fortran compiler must be consistent for BLAS, LAPACK, NumPy, and SciPy.
## For GNU compiler on 32-bit systems:
#g77 -O2 -fno-second-underscore -c *.f                     # with g77
#gfortran -O2 -std=legacy -fno-second-underscore -c *.f    # with gfortran
## OR for GNU compiler on 64-bit systems:
#g77 -O3 -m64 -fno-second-underscore -fPIC -c *.f                     # with g77
gfortran -O3 -std=legacy -m64 -fno-second-underscore -fPIC -c *.f    # with gfortran
## OR for Intel compiler:
#ifort -FI -w90 -w95 -cm -O3 -unroll -c *.f

# Continue below irrespective of compiler:
ar r libfblas.a *.o
ranlib libfblas.a
rm -rf *.o
export BLAS=~/src/BLAS-*/libfblas.a

Execute only one of the five g77/gfortran/ifort commands. I have commented out all, but the gfortran which I use. The subsequent LAPACK installation requires a Fortran 90 compiler, and since both installs should use the same Fortran compiler, g77 should not be used for BLAS.

Next, you'll need to install the LAPACK stuff. The SciPy webpage's instructions helped me here as well, but I had to modify them to suit my environment:

mkdir -p ~/src
cd ~/src/
wget http://www.netlib.org/lapack/lapack.tgz
tar xzf lapack.tgz
cd lapack-*/
cp INSTALL/make.inc.gfortran make.inc          # On Linux with lapack-3.2.1 or newer
make lapacklib
make clean
export LAPACK=~/src/lapack-*/liblapack.a

Update on 3-Sep-2015: Verified some comments today (thanks to all): Before running make lapacklib edit the make.inc file and add -fPIC option to OPTS and NOOPT settings. If you are on a 64bit architecture or want to compile for one, also add -m64. It is important that BLAS and LAPACK are compiled with these options set to the same values. If you forget the -fPIC SciPy will actually give you an error about missing symbols and will recommend this switch. The specific section of make.inc looks like this in my setup:

FORTRAN  = gfortran 
OPTS     = -O2 -frecursive -fPIC -m64
DRVOPTS  = $(OPTS)
NOOPT    = -O0 -frecursive -fPIC -m64
LOADER   = gfortran

On old machines (e.g. RedHat 5), gfortran might be installed in an older version (e.g. 4.1.2) and does not understand option -frecursive. Simply remove it from the make.inc file in such cases.

The lapack test target of the Makefile fails in my setup because it cannot find the blas libraries. If you are thorough you can temporarily move the blas library to the specified location to test the lapack. I'm a lazy person, so I trust the devs to have it working and verify only in SciPy.

Starting from Python 3.4 there's pathlib built-in library. So the code could be something like:

from pathlib import Path

filename = "mysequence.fasta"
new_filename = Path(filename).stem + ".aln"

https://docs.python.org/3.4/library/pathlib.html#pathlib.PurePath.stem

I love pathlib :)

MySQL has an undocumented syntax to sort nulls last. Place a minus sign (-) before the column name and switch the ASC to DESC:

SELECT * FROM tablename WHERE visible=1 ORDER BY -position DESC, id DESC

It is essentially the inverse of position DESC placing the NULL values last but otherwise the same as position ASC.

A good reference is here http://troels.arvin.dk/db/rdbms#select-order_by

"C:\Program Files (x86)\ffmpegX86shared\bin\ffmpeg.exe" -y -i "C:\testfile.ts" -an -vcodec libx264 -g 75 -keyint_min 12 -vb 4000k -vprofile high -level 40 -s 1920x1080 -y -threads 0 -r 25 "C:\testfile.h264"

The above worked for me on a Windows machine using a FFmpeg Win32 shared build by Kyle Schwarz. The build was compiled on: Feb 22 2013, at: 01:09:53

Note that -an defines that audio should be skipped.

I believe the example you've posted is using HTML5, which allows you to jump to any DOM element with the matching ID attribute. To support older browsers, you'll need to change:

<div id="timeline" name="timeline" ...>

To the old format:

<a name="timeline" />

You'll then be able to navigate to /academics/page.html#timeline and jump right to that section.

Also, check out this similar question.

For exporting the instances of the classes you can use this syntax:

// export index.js
const Foo = require('./my/module/foo');
const Bar = require('./my/module/bar');

module.exports = {
    Foo : new Foo(),
    Bar : new Bar()
};

// import and run method
const {Foo,Bar} = require('module_name');
Foo.test();

As I commented, there are a few places on this site that write the contents of a worksheet out to a CSV. This one and this one to point out just two.

Below is my version

• it explicitly looks out for "," inside a cell
• It also uses UsedRange - because you want to get all of the contents in the worksheet
• Uses an array for looping as this is faster than looping through worksheet cells
• I did not use FSO routines, but this is an option

The code ...

Sub makeCSV(theSheet As Worksheet)
Dim iFile As Long, myPath As String
Dim myArr() As Variant, outStr As String
Dim iLoop As Long, jLoop As Long

myPath = Application.ActiveWorkbook.Path
iFile = FreeFile
Open myPath & "\myCSV.csv" For Output Lock Write As #iFile

myArr = theSheet.UsedRange
For iLoop = LBound(myArr, 1) To UBound(myArr, 1)
    outStr = ""
    For jLoop = LBound(myArr, 2) To UBound(myArr, 2) - 1
        If InStr(1, myArr(iLoop, jLoop), ",") Then
            outStr = outStr & """" & myArr(iLoop, jLoop) & """" & ","
        Else
            outStr = outStr & myArr(iLoop, jLoop) & ","
        End If
    Next jLoop
    If InStr(1, myArr(iLoop, jLoop), ",") Then
        outStr = outStr & """" & myArr(iLoop, UBound(myArr, 2)) & """"
    Else
        outStr = outStr & myArr(iLoop, UBound(myArr, 2))
    End If
    Print #iFile, outStr
Next iLoop

Close iFile
Erase myArr

End Sub

Looking at this official google link: Youtube Live encoder settings, bitrates and resolutions they have this table:

                   240p       360p        480p        720p        1080p
Resolution      426 x 240   640 x 360   854x480     1280x720    1920x1080
Video Bitrates                   
Maximum         700 Kbps    1000 Kbps   2000 Kbps   4000 Kbps   6000 Kbps
Recommended     400 Kbps    750 Kbps    1000 Kbps   2500 Kbps   4500 Kbps
Minimum         300 Kbps    400 Kbps    500 Kbps    1500 Kbps   3000 Kbps

It would appear as though this is the case, although the numbers dont sync up to the google table above:

// the bitrates, video width and file names for this clip
      bitrates: [
        { url: "bbb-800.mp4", width: 480, bitrate: 800 }, //360p video
        { url: "bbb-1200.mp4", width: 720, bitrate: 1200 }, //480p video
        { url: "bbb-1600.mp4", width: 1080, bitrate: 1600 } //720p video
      ],

My problem was about network SSID broadcasting.

I've tried all the solutions above but still couldn't connect my device, there was no 'globe' icon for my device at all. Then I found that for some reason my network had turned its SSID broadcasting off(tho I could still connect the network by inputing the SSID manually). Once I turned the SSID broadcasting on, I could connect my device via 'Connect via IP Address...'.

One more for loop variant, looks cleaner to me than one with enumerate():

for idx in range(len(list)):
    list[idx]=... # set a new value
    # some other code which doesn't let you use a list comprehension

You can use command

svn add * force--

or

svn add <directory/file name>

If your files/directories are not adding recursively. Then check this.

Recursive adding is default property. You can see in SVN book.

Issue can be in your ignore list or global properties.

I got solution google issue tracker

Check global properties for ignoring star(*)

• Right click in your repo in window. Select TortoiseSVN > Properties.
• See if you don't have a property svn:global-ignores with a value of *
• If you have property with star(*) then it will ignore recursive adding. So remove this property.

Check global ignore pattern for ignoring star(*)

• Right click in your repo in window. Select TortoiseSVN > Settings > General.
• See in Global Ignore Pattern, if you don't have set star(*) there.
• If you found star(*), remove this property.

This guy also explained why this property added in my project.

The most like way that it got there is that someone right-clicked a file without any extension and selected TortoiseSVN -> SVN Ignore -> * (recursively), and then committed this.

You can check the log to see who committed that property change, find out what they were actually trying to do, and ask them to be more careful in future. :)

Another way to get the selected tab index is:

var index = jQuery('#tabs').data('tabs').options.selected;

The idiom (shared by quite a few other languages) for an unused variable is a single underscore _. Code analysers typically won't complain about _ being unused, and programmers will instantly know it's a shortcut for i_dont_care_wtf_you_put_here. There is no way to iterate without having an item variable - as the Zen of Python puts it, "special cases aren't special enough to break the rules".

Adding to Gisheri's answer

Following code worked for me

 var drawingManager = new google.maps.drawing.DrawingManager({
    drawingMode: google.maps.drawing.OverlayType.MARKER,
    drawingControl: true,
    drawingControlOptions: {
      position: google.maps.ControlPosition.TOP_CENTER,
      drawingModes: [
        google.maps.drawing.OverlayType.POLYGON
      ]
    },
    markerOptions: {
      icon: 'images/beachflag.png'
    },
    circleOptions: {
      fillColor: '#ffff00',
      fillOpacity: 1,
      strokeWeight: 5,
      clickable: false,
      editable: true,
      zIndex: 1
    }

  });

  google.maps.event.addListener(drawingManager, 'overlaycomplete', function(polygon) {
      //console.log(polygon.overlay.latLngs.j[0].j);return false;
        $.each(polygon.overlay.latLngs.j[0].j, function(key, LatLongsObject){
            var LatLongs    =   LatLongsObject;

            var lat = LatLongs.k;
            var lon = LatLongs.B;
           console.log("Lat is: "+lat+" Long is: "+lon); //do something with the coordinates

        });

I was having this problem and added this JavaScript to the bottom of my page (read it at https://www.webtrickshome.com/faq/how-to-stop-form-resubmission-on-page-refresh) and it seemed to work. It seems much simpler a solution. Any drawbacks?

Format to send a WhatsApp message to a specific number (updated Nov 2018)

<a href="https://wa.me/whatsappphonenumber/?text=urlencodedtext"></a>

where

whatsappphonenumber is a full phone number in international format

urlencodedtext is the URL-encoded pre-filled message.

Example:

1. Create a link with a pre-filled message that will automatically appear in the text field of a chat, to be sent to a specific number

   Send I am interested in your car for sale to +001-(555)1234567

   https://wa.me/15551234567?text=I%20am%20interested%20in%20your%20car%20for%20sale

   Note :

   Use: https://wa.me/15551234567

   Don't use: https://wa.me/+001-(555)1234567

2. Create a link with just a pre-filled message that will automatically appear in the text field of a chat, number will be chosen by the user

   Send I am enquiring about the apartment listing

   https://wa.me/?text=I%20am%20enquiring%20about%20the%20apartment%20listing

   After clicking on the link, user will be shown a list of contacts they can send the pre-filled message to.

You can also set the HTTP port in .sbtopts in the project directory:

-Dhttp.port=9001

Then you do not have to remember to add it to the run task every time.

Tested with Play 2.1.1.

Solution without fixing size on your margin

.content .right{
    overflow: auto; 
    background-color: red;
}

+1 for Merkuro, but if the size of the float changes your fixed margin will fail. If u use above CSS on the right div it will nicely change size with changing size on the left float. It is a bit more flexible like that. Check the fiddle here: http://jsfiddle.net/9ZHBK/144/

There are two models for implementing classes and instances in JavaScript: the prototyping way, and the closure way. Both have advantages and drawbacks, and there are plenty of extended variations. Many programmers and libraries have different approaches and class-handling utility functions to paper over some of the uglier parts of the language.

The result is that in mixed company you will have a mishmash of metaclasses, all behaving slightly differently. What's worse, most JavaScript tutorial material is terrible and serves up some kind of in-between compromise to cover all bases, leaving you very confused. (Probably the author is also confused. JavaScript's object model is very different to most programming languages, and in many places straight-up badly designed.)

Let's start with the prototype way. This is the most JavaScript-native you can get: there is a minimum of overhead code and instanceof will work with instances of this kind of object.

function Shape(x, y) {
    this.x= x;
    this.y= y;
}

We can add methods to the instance created by new Shape by writing them to the prototype lookup of this constructor function:

Shape.prototype.toString= function() {
    return 'Shape at '+this.x+', '+this.y;
};

Now to subclass it, in as much as you can call what JavaScript does subclassing. We do that by completely replacing that weird magic prototype property:

function Circle(x, y, r) {
    Shape.call(this, x, y); // invoke the base class's constructor function to take co-ords
    this.r= r;
}
Circle.prototype= new Shape();

before adding methods to it:

Circle.prototype.toString= function() {
    return 'Circular '+Shape.prototype.toString.call(this)+' with radius '+this.r;
}

This example will work and you will see code like it in many tutorials. But man, that new Shape() is ugly: we're instantiating the base class even though no actual Shape is to be created. It happens to work in this simple case because JavaScript is so sloppy: it allows zero arguments to be passed in, in which case x and y become undefined and are assigned to the prototype's this.x and this.y. If the constructor function were doing anything more complicated, it would fall flat on its face.

So what we need to do is find a way to create a prototype object which contains the methods and other members we want at a class level, without calling the base class's constructor function. To do this we are going to have to start writing helper code. This is the simplest approach I know of:

function subclassOf(base) {
    _subclassOf.prototype= base.prototype;
    return new _subclassOf();
}
function _subclassOf() {};

This transfers the base class's members in its prototype to a new constructor function which does nothing, then uses that constructor. Now we can write simply:

function Circle(x, y, r) {
    Shape.call(this, x, y);
    this.r= r;
}
Circle.prototype= subclassOf(Shape);

instead of the new Shape() wrongness. We now have an acceptable set of primitives to built classes.

There are a few refinements and extensions we can consider under this model. For example here is a syntactical-sugar version:

Function.prototype.subclass= function(base) {
    var c= Function.prototype.subclass.nonconstructor;
    c.prototype= base.prototype;
    this.prototype= new c();
};
Function.prototype.subclass.nonconstructor= function() {};

...

function Circle(x, y, r) {
    Shape.call(this, x, y);
    this.r= r;
}
Circle.subclass(Shape);

Either version has the drawback that the constructor function cannot be inherited, as it is in many languages. So even if your subclass adds nothing to the construction process, it must remember to call the base constructor with whatever arguments the base wanted. This can be slightly automated using apply, but still you have to write out:

function Point() {
    Shape.apply(this, arguments);
}
Point.subclass(Shape);

So a common extension is to break out the initialisation stuff into its own function rather than the constructor itself. This function can then inherit from the base just fine:

function Shape() { this._init.apply(this, arguments); }
Shape.prototype._init= function(x, y) {
    this.x= x;
    this.y= y;
};

function Point() { this._init.apply(this, arguments); }
Point.subclass(Shape);
// no need to write new initialiser for Point!

Now we've just got the same constructor function boilerplate for each class. Maybe we can move that out into its own helper function so we don't have to keep typing it, for example instead of Function.prototype.subclass, turning it round and letting the base class's Function spit out subclasses:

Function.prototype.makeSubclass= function() {
    function Class() {
        if ('_init' in this)
            this._init.apply(this, arguments);
    }
    Function.prototype.makeSubclass.nonconstructor.prototype= this.prototype;
    Class.prototype= new Function.prototype.makeSubclass.nonconstructor();
    return Class;
};
Function.prototype.makeSubclass.nonconstructor= function() {};

...

Shape= Object.makeSubclass();
Shape.prototype._init= function(x, y) {
    this.x= x;
    this.y= y;
};

Point= Shape.makeSubclass();

Circle= Shape.makeSubclass();
Circle.prototype._init= function(x, y, r) {
    Shape.prototype._init.call(this, x, y);
    this.r= r;
};

...which is starting to look a bit more like other languages, albeit with slightly clumsier syntax. You can sprinkle in a few extra features if you like. Maybe you want makeSubclass to take and remember a class name and provide a default toString using it. Maybe you want to make the constructor detect when it has accidentally been called without the new operator (which would otherwise often result in very annoying debugging):

Function.prototype.makeSubclass= function() {
    function Class() {
        if (!(this instanceof Class))
            throw('Constructor called without "new"');
        ...

Maybe you want to pass in all the new members and have makeSubclass add them to the prototype, to save you having to write Class.prototype... quite so much. A lot of class systems do that, eg:

Circle= Shape.makeSubclass({
    _init: function(x, y, z) {
        Shape.prototype._init.call(this, x, y);
        this.r= r;
    },
    ...
});

There are a lot of potential features you might consider desirable in an object system and no-one really agrees on one particular formula.

The closure way, then. This avoids the problems of JavaScript's prototype-based inheritance, by not using inheritance at all. Instead:

function Shape(x, y) {
    var that= this;

    this.x= x;
    this.y= y;

    this.toString= function() {
        return 'Shape at '+that.x+', '+that.y;
    };
}

function Circle(x, y, r) {
    var that= this;

    Shape.call(this, x, y);
    this.r= r;

    var _baseToString= this.toString;
    this.toString= function() {
        return 'Circular '+_baseToString(that)+' with radius '+that.r;
    };
};

var mycircle= new Circle();

Now every single instance of Shape will have its own copy of the toString method (and any other methods or other class members we add).

The bad thing about every instance having its own copy of each class member is that it's less efficient. If you are dealing with large numbers of subclassed instances, prototypical inheritance may serve you better. Also calling a method of the base class is slightly annoying as you can see: we have to remember what the method was before the subclass constructor overwrote it, or it gets lost.

[Also because there is no inheritance here, the instanceof operator won't work; you would have to provide your own mechanism for class-sniffing if you need it. Whilst you could fiddle the prototype objects in a similar way as with prototype inheritance, it's a bit tricky and not really worth it just to get instanceof working.]

The good thing about every instance having its own method is that the method may then be bound to the specific instance that owns it. This is useful because of JavaScript's weird way of binding this in method calls, which has the upshot that if you detach a method from its owner:

var ts= mycircle.toString;
alert(ts());

then this inside the method won't be the Circle instance as expected (it'll actually be the global window object, causing widespread debugging woe). In reality this typically happens when a method is taken and assigned to a setTimeout, onclick or EventListener in general.

With the prototype way, you have to include a closure for every such assignment:

setTimeout(function() {
    mycircle.move(1, 1);
}, 1000);

or, in the future (or now if you hack Function.prototype) you can also do it with function.bind():

setTimeout(mycircle.move.bind(mycircle, 1, 1), 1000);

if your instances are done the closure way, the binding is done for free by the closure over the instance variable (usually called that or self, though personally I would advise against the latter as self already has another, different meaning in JavaScript). You don't get the arguments 1, 1 in the above snippet for free though, so you would still need another closure or a bind() if you need to do that.

There are lots of variants on the closure method too. You may prefer to omit this completely, creating a new that and returning it instead of using the new operator:

function Shape(x, y) {
    var that= {};

    that.x= x;
    that.y= y;

    that.toString= function() {
        return 'Shape at '+that.x+', '+that.y;
    };

    return that;
}

function Circle(x, y, r) {
    var that= Shape(x, y);

    that.r= r;

    var _baseToString= that.toString;
    that.toString= function() {
        return 'Circular '+_baseToString(that)+' with radius '+r;
    };

    return that;
};

var mycircle= Circle(); // you can include `new` if you want but it won't do anything

Which way is “proper”? Both. Which is “best”? That depends on your situation. FWIW I tend towards prototyping for real JavaScript inheritance when I'm doing strongly OO stuff, and closures for simple throwaway page effects.

But both ways are quite counter-intuitive to most programmers. Both have many potential messy variations. You will meet both (as well as many in-between and generally broken schemes) if you use other people's code/libraries. There is no one generally-accepted answer. Welcome to the wonderful world of JavaScript objects.

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.

As far as your question goes: no, if activating from .ini is not enough and you can't upgrade PHP, there's not much you can do. Some modules, but not all, can be added without recompilation (zypper install php5-soap, yum install php-soap). If it is not enough, try installing some PEAR class for interpreted SOAP support (NuSOAP, etc.).

In general, the double-dash --switches are designed to be used when recompiling PHP from scratch.

You would download the PHP source package (as a compressed .tgz tarball, say), expand it somewhere and then, e.g. under Linux, run the configure script

./configure --prefix ...

The configure command used by your PHP may be shown with phpinfo(). Repeating it identical should give you an exact copy of the PHP you now have installed. Adding --enable-soap will then enable SOAP in addition to everything else.

That said, if you aren't familiar with PHP recompilation, don't do it. It also requires several ancillary libraries that you might, or might not, have available - freetype, gd, libjpeg, XML, expat, and so on and so forth (it's not enough they are installed; they must be a developer version, i.e. with headers and so on; in most distributions, having libjpeg installed might not be enough, and you might need libjpeg-dev also).

I have to keep a separate virtual machine with everything installed for my recompilation purposes.

$(selectedDOM).find();

function looking for all dom objects inside the selected DOM. i.e.

<div id="mainDiv">
    <p>Paragraph 1</p>
    <p>Paragraph 2</p>
    <div id="innerDiv">
         <a href="#">link</a>
         <p>Paragraph 3</p>
    </div>
</div>

here if you write;

$("#mainDiv").find("p");

you will get tree p elements together. On the other side,

$("#mainDiv").children("p");

Function searching in the just children DOMs of the selected DOM object. So, by this code you will get just paragraph 1 and paragraph 2. It is so beneficial to prevent browser doing unnecessary progress.

Like this

SELECT DISTINCT Table1.Column1
FROM Table1
WHERE NOT EXISTS( SELECT * FROM Table2
    WHERE Table1.Column1 = Table2.Column1  )

You want NOT EXISTS, not "Not Equal"

By the way, you rarely want to write a FROM clause like this:

FROM Table1, Table2

as this means "FROM all combinations of every row in Table1 with every row in Table2..." Usually that's a lot more result rows than you ever want to see. And in the rare case that you really do want to do that, the more accepted syntax is:

FROM Table1 CROSS JOIN Table2

Dynamic programming problems can be solved using either bottom-up or top-down approaches.

Generally, the bottom-up approach uses the tabulation technique, while the top-down approach uses the recursion (with memorization) technique.

But you can also have bottom-up and top-down approaches using recursion as shown below.

Bottom-Up: Start with the base condition and pass the value calculated until now recursively. Generally, these are tail recursions.

int n = 5;
fibBottomUp(1, 1, 2, n);

private int fibBottomUp(int i, int j, int count, int n) {
    if (count > n) return 1;
    if (count == n) return i + j;
    return fibBottomUp(j, i + j, count + 1, n);
}

Top-Down: Start with the final condition and recursively get the result of its sub-problems.

int n = 5;
fibTopDown(n);

private int fibTopDown(int n) {
    if (n <= 1) return 1;
    return fibTopDown(n - 1) + fibTopDown(n - 2);
}

There are a couple of parallization bugs in SQL server with abnormal input. OPTION(MAXDOP 1) will sidestep them.

EDIT: Old. My testing was done largely on SQL 2005. Most of these seem to not exist anymore, but every once in awhile we question the assumption when SQL 2014 does something dumb and we go back to the old way and it works. We never managed to demonstrate that it wasn't just a bad plan generation on more recent cases though since SQL server can be relied on to get the old way right in newer versions. Since all cases were IO bound queries MAXDOP 1 doesn't hurt.

simplified generic form,

int div_up(int n, int d) {
    return n / d + (((n < 0) ^ (d > 0)) && (n % d));
} //i.e. +1 iff (not exact int && positive result)

For a more generic answer, C++ functions for integer division with well defined rounding strategy

It's pretty straightforward using [ to extract:

grep will give you the position in which it matched your search pattern (unless you use value = TRUE).

grep("^G45", My.Data$x)
# [1] 2

Since you're searching within the values of a single column, that actually corresponds to the row index. So, use that with [ (where you would use My.Data[rows, cols] to get specific rows and columns).

My.Data[grep("^G45", My.Data$x), ]
#      x y
# 2 G459 2

The help-page for subset shows how you can use grep and grepl with subset if you prefer using this function over [. Here's an example.

subset(My.Data, grepl("^G45", My.Data$x))
#      x y
# 2 G459 2

As of R 3.3, there's now also the startsWith function, which you can again use with subset (or with any of the other approaches above). According to the help page for the function, it's considerably faster than using substring or grepl.

subset(My.Data, startsWith(as.character(x), "G45"))
#      x y
# 2 G459 2

To well understand the behaviour, you can run this code:

#include <iostream>

class MyClass
{
  public:
    MyClass() { std::cout << "run constructor MyClass::MyClass()" << std::endl; }
    ~MyClass() { std::cout << "run destructor MyClass::~MyClass()" << std::endl; }
    MyClass(const MyClass& x) { std::cout << "run copy constructor MyClass::MyClass(const MyClass&)" << std::endl; }
    MyClass& operator = (const MyClass& x) { std::cout << "run assignation MyClass::operator=(const MyClass&)" << std::endl; }
};

MyClass my_function()
{
  std::cout << "run my_function()" << std::endl;
  MyClass a;
  std::cout << "my_function is going to return a..." << std::endl;
  return a;
}

int main(int argc, char** argv)
{
  MyClass b = my_function();

  MyClass c;
  c = my_function();

  return 0;
}

The output is the following:

run my_function()
run constructor MyClass::MyClass()
my_function is going to return a...
run constructor MyClass::MyClass()
run my_function()
run constructor MyClass::MyClass()
my_function is going to return a...
run assignation MyClass::operator=(const MyClass&)
run destructor MyClass::~MyClass()
run destructor MyClass::~MyClass()
run destructor MyClass::~MyClass()

Note that this example was provided in C++03 context, it could be improved for C++ >= 11

You could use table, i.e.

n_occur <- data.frame(table(vocabulary$id))

gives you a data frame with a list of ids and the number of times they occurred.

n_occur[n_occur$Freq > 1,]

tells you which ids occurred more than once.

vocabulary[vocabulary$id %in% n_occur$Var1[n_occur$Freq > 1],]

returns the records with more than one occurrence.

I have been having a similar issue. I wanted a percentage height and top-margin for my container div, but the body would take on the margin of the container div. I think I figured out a solution.

Here is my original (problem) code:

html {
    height:100%;
}

body {
    height:100%;                    
    margin-top:0%;
    padding:0%; 
}

#pageContainer {
    position:relative;
    width:96%;                  /* 100% - (margin * 2) */
    height:96%;                 /* 100% - (margin * 2) */           
    margin:2% auto 0% auto;
    padding:0%;
}

My solution was to set the height of the body the same as the height of the container.
html { height:100%; }

body {
    height:96%;     /* 100% * (pageContainer*2) */
    margin-top:0%;
    padding:0%; 
}

#pageContainer {
    position:relative;
    width:96%;                  /* 100% - (margin * 2) */
    height:96%;                 /* 100% - (margin * 2) */           
    margin:2% auto 0% auto;
    padding:0%;
}

I haven't tested it in every browser, but this seems to work.

You forgot to add std:: namespace prefix to vector class name.

Django forms module uses __call__ method nicely to implement a consistent API for form validation. You can write your own validator for a form in Django as a function.

def custom_validator(value):
    #your validation logic

Django has some default built-in validators such as email validators, url validators etc., which broadly fall under the umbrella of RegEx validators. To implement these cleanly, Django resorts to callable classes (instead of functions). It implements default Regex Validation logic in a RegexValidator and then extends these classes for other validations.

class RegexValidator(object):
    def __call__(self, value):
        # validation logic

class URLValidator(RegexValidator):
    def __call__(self, value):
        super(URLValidator, self).__call__(value)
        #additional logic

class EmailValidator(RegexValidator):
    # some logic

Now both your custom function and built-in EmailValidator can be called with the same syntax.

for v in [custom_validator, EmailValidator()]:
    v(value) # <-----

As you can see, this implementation in Django is similar to what others have explained in their answers below. Can this be implemented in any other way? You could, but IMHO it will not be as readable or as easily extensible for a big framework like Django.

Use List<> to build up an 'array' of unknown length.

Use List<>.ToArray() to return a real array, and not a List.

var list = new List<int>();
list.Add(1);
list.Add(2);
list.Add(3);
var array = list.ToArray();

Declaration

Declaration, generally, refers to the introduction of a new name in the program. For example, you can declare a new function by describing it's "signature":

void xyz();

or declare an incomplete type:

class klass;
struct ztruct;

and last but not least, to declare an object:

int x;

It is described, in the C++ standard, at §3.1/1 as:

A declaration (Clause 7) may introduce one or more names into a translation unit or redeclare names introduced by previous declarations.

Definition

A definition is a definition of a previously declared name (or it can be both definition and declaration). For example:

int x;
void xyz() {...}
class klass {...};
struct ztruct {...};
enum { x, y, z };

Specifically the C++ standard defines it, at §3.1/1, as:

A declaration is a definition unless it declares a function without specifying the function’s body (8.4), it contains the extern specifier (7.1.1) or a linkage-specification25 (7.5) and neither an initializer nor a function- body, it declares a static data member in a class definition (9.2, 9.4), it is a class name declaration (9.1), it is an opaque-enum-declaration (7.2), it is a template-parameter (14.1), it is a parameter-declaration (8.3.5) in a function declarator that is not the declarator of a function-definition, or it is a typedef declaration (7.1.3), an alias-declaration (7.1.3), a using-declaration (7.3.3), a static_assert-declaration (Clause 7), an attribute- declaration (Clause 7), an empty-declaration (Clause 7), or a using-directive (7.3.4).

Initialization

Initialization refers to the "assignment" of a value, at construction time. For a generic object of type T, it's often in the form:

T x = i;

but in C++ it can be:

T x(i);

or even:

T x {i};

with C++11.

Conclusion

So does it mean definition equals declaration plus initialization?

It depends. On what you are talking about. If you are talking about an object, for example:

int x;

This is a definition without initialization. The following, instead, is a definition with initialization:

int x = 0;

In certain context, it doesn't make sense to talk about "initialization", "definition" and "declaration". If you are talking about a function, for example, initialization does not mean much.

So, the answer is no: definition does not automatically mean declaration plus initialization.

Yes. Strings can be seen as character arrays, and the way to access a position of an array is to use the [] operator. Usually there's no problem at all in using $str[0] (and I'm pretty sure is much faster than the substr() method).

There is only one caveat with both methods: they will get the first byte, rather than the first character. This is important if you're using multibyte encodings (such as UTF-8). If you want to support that, use mb_substr(). Arguably, you should always assume multibyte input these days, so this is the best option, but it will be slightly slower.

func readToDisplayUsingFile1(f *os.File){
    defer f.Close()
    reader := bufio.NewReader(f)
    contents, _ := ioutil.ReadAll(reader)
    lines := strings.Split(string(contents), '\n')
}

or

func readToDisplayUsingFile1(f *os.File){
    defer f.Close()
    slice := make([]string,0)

    reader := bufio.NewReader(f)

    for{

    str, err := reader.ReadString('\n')
    if err == io.EOF{
        break
    }

        slice = append(slice, str)
    }

If you want to edit the decoded JSON, try getting it as an associative array instead of an array of objects.

$data = json_decode($json, TRUE);

$IFS comment hacks

This hack uses parameter expansion on $IFS, which is used to separate words in commands:

$ echo foo${IFS}bar
foo bar

Similarly:

$ echo foo${IFS#comment}bar
foo bar

Using this, you can put a comment on a command line with contination:

$ echo foo${IFS# Comment here} \
> bar
foo bar

but the comment will need to be before the \ continuation.

Note that parameter expansion is performed inside the comment:

$ ls file
ls: cannot access 'file': No such file or directory
$ echo foo${IFS# This command will create file: $(touch file)}bar
foo bar
$ ls file
file

Rare exception

The only rare case this fails is if $IFS previously started with the exact text which is removed via the expansion (ie, after the # character):

$ IFS=x
$ echo foo${IFS#y}bar
foo bar
$ echo foo${IFS#x}bar
foobar

Note the final foobar has no space, illustrating the issue.

Since $IFS contains only whitespace by default, it's extremely unlikely you'll run into this problem.

Credit to @pjh's comment which sparked off this answer.

Another option is using the map function of the purrr package.

library(purrr)
map(df,class)

You need to add uppercase L at the end like so

long i = 12345678910L;

Same goes true for float with 3.0f

Which should answer both of your questions

You want to pass the function object hi to your loop() function, not the result of a call to hi() (which is None since hi() doesn't return anything).

So try this:

>>> loop(hi, 5)
hi
hi
hi
hi
hi

Perhaps this will help you understand better:

>>> print hi()
hi
None
>>> print hi
<function hi at 0x0000000002422648>

Add Regular to syntax and use gfn:

set gfn= Monospace\ Regular:h13

You can use the 're' module in Python 3.
If you indeed do, use this:

re.search('\s', word)

This should return either 'true' if there's a match, or 'false' if there isn't any.

See this example, initializes the map to "San Diego, CA".

If you need to check the contents of the string before converting to Date format:

// Convert 'M/D/YY' to Date()
mdyToDate = function(mdy) {
  var d = mdy.split(/[\/\-\.]/, 3);

  if (d.length != 3) return null;

  // Check if date is valid
  var mon = parseInt(d[0]), 
      day = parseInt(d[1]),
      year= parseInt(d[2]);
  if (d[2].length == 2) year += 2000;
  if (day <= 31 && mon <= 12 && year >= 2015)
    return new Date(year, mon - 1, day);

  return null;

I had the same problem in Safari and Chrome (the only ones I've tested) but I just did something that seems to work, at least I haven't been able to reproduce the problem since I added the solution. What I did was add a metatag to the header with a generated timstamp. Doesn't seem right but it's simple :)

<meta name="304workaround" content="2013-10-24 21:17:23">

Update P.S As far as I can tell, the problem disappears when I remove my node proxy (by proxy i mean both express.vhost and http-proxy module), which is weird...

I had a similar issue where one of the arrays was modified. I was using it for $httpBackend, and the returned object from that was actually a $promise object containing the array (not an Array object).

You can create a jasmine matcher to match the array by creating a toBeArray function:

beforeEach(function() {
  'use strict';
  this.addMatchers({
    toBeArray: function(array) {
      this.message = function() {
        return "Expected " + angular.mock.dump(this.actual) + " to be array " + angular.mock.dump(array) + ".";
      };
      var arraysAreSame = function(x, y) {
         var arraysAreSame = true;
         for(var i; i < x.length; i++)
            if(x[i] !== y[i])
               arraysAreSame = false;
         return arraysAreSame;
      };
      return arraysAreSame(this.actual, array);
    }
  });
});

And then just use it in your tests like the other jasmine matchers:

it('should compare arrays properly', function() {

I literally striped out this line of code from content-single-popup.php located in woocommerce folder in my theme directory.

global $product; 
echo $product->get_categories( ', ', ' ' . _n( ' ', '  ', $cat_count, 'woocommerce' ) . ' ', ' ' );

Since my theme that I am working on has integrated woocommerce in it, this was my solution.

Here are brief list:

• JQuery with JSON stuff. (http://www.w3schools.com/xml/xml_http.asp)

• $_SESSION - probably best way

• Custom cookie - will not *always* work.

• HTTP headers - some proxy can block it.

• database such MySQL, Postgres or something else such Redis or Memcached (e.g. similar to home-made session, "locked" by IP address)

• APC - similar to database, will not *always* work.

• HTTP_REFERRER

• URL hash parameter , e.g. http://domain.com/page.php#param - you will need some JavaScript to collect the hash. - gmail heavy use this.

In Swift:

var uuid: String = NSUUID().UUIDString
println("uuid: \(uuid)")

It should be :

public async Task<ActionResult> GetSomeJsonData()
{
    var model = // ... get data or build model etc.

    return Json(new { Data = model }, JsonRequestBehavior.AllowGet); 
}

or more simply:

return Json(model, JsonRequestBehavior.AllowGet); 

I did notice that you are calling GetResources() from another ActionResult which wont work. If you are looking to get JSON back, you should be calling GetResources() from ajax directly...

super is a keyword. It is used inside a sub-class method definition to call a method defined in the superclass. Private methods of the superclass cannot be called. Only public and protected methods can be called by the super keyword. It is also used by class constructors to invoke constructors of its parent class.

Check here for further explanation.

You have a view model to which your view is strongly typed => use strongly typed helpers:

<%= Html.DropDownListFor(
    x => x.SelectedAccountId, 
    new SelectList(Model.Accounts, "Value", "Text")
) %>

Also notice that I use a SelectList for the second argument.

And in your controller action you were returning the view model passed as argument and not the one you constructed inside the action which had the Accounts property correctly setup so this could be problematic. I've cleaned it a bit:

public ActionResult AccountTransaction()
{
    var accounts = Services.AccountServices.GetAccounts(false);
    var viewModel = new AccountTransactionView
    {
        Accounts = accounts.Select(a => new SelectListItem
        {
            Text = a.Description,
            Value = a.AccountId.ToString()
        })
    };
    return View(viewModel);
}

I think it is the version error.

try installing this in following order:

1. sudo apt-get install python3-mysqldb

2. pip3 install mysqlclient

3. python3 manage.py makemigrations

4. python3 manage.py migrate

Copy should be used for NSString. If it's Mutable, then it gets copied. If it's not, then it just gets retained. Exactly the semantics that you want in an app (let the type do what's best).

I added these to my .bash_profile so I can have access to tabname and newtab

tabname() {
  printf "\e]1;$1\a"
}

new_tab() {
  TAB_NAME=$1
  COMMAND=$2
  osascript \
    -e "tell application \"Terminal\"" \
    -e "tell application \"System Events\" to keystroke \"t\" using {command down}" \
    -e "do script \"printf '\\\e]1;$TAB_NAME\\\a'; $COMMAND\" in front window" \
    -e "end tell" > /dev/null
}

So when you're on a particular tab you can just type

tabname "New TabName"

to organize all the open tabs you have. It's much better than getting info on the tab and changing it there.

I have heard an explanation, that is:" NP-Completeness is probably one of the more enigmatic ideas in the study of algorithms. "NP" stands for "nondeterministic polynomial time," and is the name for what is called a complexity class to which problems can belong. The important thing about the NP complexity class is that problems within that class can be verified by a polynomial time algorithm. As an example, consider the problem of counting stuff. Suppose there are a bunch of apples on a table. The problem is "How many apples are there?" You are provided with a possible answer, 8. You can verify this answer in polynomial time by using the algorithm of, duh, counting the apples. Counting the apples happens in O(n) (that's Big-oh notation) time, because it takes one step to count each apple. For n apples, you need n steps. This problem is in the NP complexity class.

A problem is classified as NP-complete if it can be shown that it is both NP-Hard and verifiable in polynomial time. Without going too deeply into the discussion of NP-Hard, suffice it to say that there are certain problems to which polynomial time solutions have not been found. That is, it takes something like n! (n factorial) steps to solve them. However, if you're given a solution to an NP-Complete problem, you can verify it in polynomial time.

A classic example of an NP-Complete problem is The Traveling Salesman Problem."

The best way to do it is to use SerializationUtils from Apache Commons Lang.

To serialize:

byte[] data = SerializationUtils.serialize(yourObject);

To deserialize:

YourObject yourObject = SerializationUtils.deserialize(data)

As mentioned, this requires Commons Lang library. It can be imported using Gradle:

compile 'org.apache.commons:commons-lang3:3.5'

Maven:

<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-lang3 -->
<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-lang3</artifactId>
    <version>3.5</version>
</dependency>

Jar file

And more ways mentioned here

Alternatively, the whole collection can be imported. Refer this link

As of API 26, getDeviceId() is deprecated. If you need to get the IMEI of the device, use the following:

 String deviceId = "";
    if (Build.VERSION.SDK_INT >= 26) {
        deviceId = getSystemService(TelephonyManager.class).getImei();
    }else{
        deviceId = getSystemService(TelephonyManager.class).getDeviceId();
    }

JsonFx can deserialize JSON content into dynamic objects.

Serialize to/from dynamic types (default for .NET 4.0):

var reader = new JsonReader(); var writer = new JsonWriter();

string input = @"{ ""foo"": true, ""array"": [ 42, false, ""Hello!"", null ] }";
dynamic output = reader.Read(input);
Console.WriteLine(output.array[0]); // 42
string json = writer.Write(output);
Console.WriteLine(json); // {"foo":true,"array":[42,false,"Hello!",null]}

I've tried the following:

codeEditText.setInputType(InputType.TYPE_NULL);

this.codeEditText.setOnFocusChangeListener(new OnFocusChangeListener() {

  @Override
  public void onFocusChange(View v, boolean hasFocus) {

    if (hasFocus) {

      pickCode();

    }

  }

});
this.codeEditText.setOnClickListener(new OnClickListener() {

  @Override
  public void onClick(View v) {

    pickCode();

  }

});

but the problem was that if the edit text is the first in the form then it gets the focus and the pickCode() code which launches a new activity is called straight away. So I modified the code as follows and it seems to work quite well (except I cannot set the focus on the text edit but I don't need to):

itemCodeEditText.setFocusable(false);

this.itemCodeEditText.setOnClickListener(new OnClickListener() {

  @Override
  public void onClick(View v) {

    pickItem();

  }

});

Just another thing... Instead of System.out.println("Error Message Here"), use System.err.println("Error Message Here"). This will allow you to distinguish the differences between errors and normal code functioning by displaying the errors(i.e. everything inside System.err.println()) in red.

NOTE: It also works when used with System.err.print("Error Message Here")

array.split(' ').slice(-1)[0]

The best one ever and my favorite.

If you mean milliseconds since epoch you could do

ptime time_t_epoch(date(1970,1,1)); 
ptime now = microsec_clock::local_time();
time_duration diff = now - time_t_epoch;
x = diff.total_milliseconds();

However, it's not particularly clear what you're after.

Have a look at the example in the documentation for DateTime at Boost Date Time

I suggest using JavaScript's Array method filter() to identify an element by value. It filters data by using a "function to test each element of the array. Return true to keep the element, false otherwise.."

The following function filters the data, returning data for which the callback returns true, i.e. where data.code equals the requested country code.

function getCountryByCode(code) {
  return data.filter(
      function(data){ return data.code == code }
  );
}

var found = getCountryByCode('DZ');

See the demonstration below:

var data = [{_x000D_
  "name": "Afghanistan",_x000D_
  "code": "AF"_x000D_
}, {_x000D_
  "name": "Åland Islands",_x000D_
  "code": "AX"_x000D_
}, {_x000D_
  "name": "Albania",_x000D_
  "code": "AL"_x000D_
}, {_x000D_
  "name": "Algeria",_x000D_
  "code": "DZ"_x000D_
}];_x000D_
_x000D_
_x000D_
function getCountryByCode(code) {_x000D_
  return data.filter(_x000D_
    function(data) {_x000D_
      return data.code == code_x000D_
    }_x000D_
  );_x000D_
}_x000D_
_x000D_
var found = getCountryByCode('DZ');_x000D_
_x000D_
document.getElementById('output').innerHTML = found[0].name;

<div id="output"></div>

Here's a JSFiddle.

prepare return a boolean only when it fails therefore FALSE, to avoid the error you need to check if it is True first before executing:

$sql = 'SELECT value, param FROM ws_settings WHERE name = ?';
if($query = $this->db->conn->prepare($sql)){
    $query->bind_param('s', $setting);
    $query->execute();
    //rest of code here
}else{
   //error !! don't go further
   var_dump($this->db->error);
}

This should give what you want:

FLOOR(RAND() * 401) + 100

Generically, FLOOR(RAND() * (<max> - <min> + 1)) + <min> generates a number between <min> and <max> inclusive.

Update

This full statement should work:

SELECT name, address, FLOOR(RAND() * 401) + 100 AS `random_number` 
FROM users

The solution is to negate your values when you store them in the heap, or invert your object comparison like so:

import heapq

class MaxHeapObj(object):
  def __init__(self, val): self.val = val
  def __lt__(self, other): return self.val > other.val
  def __eq__(self, other): return self.val == other.val
  def __str__(self): return str(self.val)

Example of a max-heap:

maxh = []
heapq.heappush(maxh, MaxHeapObj(x))
x = maxh[0].val  # fetch max value
x = heapq.heappop(maxh).val  # pop max value

But you have to remember to wrap and unwrap your values, which requires knowing if you are dealing with a min- or max-heap.

MinHeap, MaxHeap classes

Adding classes for MinHeap and MaxHeap objects can simplify your code:

class MinHeap(object):
  def __init__(self): self.h = []
  def heappush(self, x): heapq.heappush(self.h, x)
  def heappop(self): return heapq.heappop(self.h)
  def __getitem__(self, i): return self.h[i]
  def __len__(self): return len(self.h)

class MaxHeap(MinHeap):
  def heappush(self, x): heapq.heappush(self.h, MaxHeapObj(x))
  def heappop(self): return heapq.heappop(self.h).val
  def __getitem__(self, i): return self.h[i].val

Example usage:

minh = MinHeap()
maxh = MaxHeap()
# add some values
minh.heappush(12)
maxh.heappush(12)
minh.heappush(4)
maxh.heappush(4)
# fetch "top" values
print(minh[0], maxh[0])  # "4 12"
# fetch and remove "top" values
print(minh.heappop(), maxh.heappop())  # "4 12"

Although you could certainly use the compareTo method on an Integer instance, it's not clear when reading the code, so you should probably avoid doing so.

Java allows you to use autoboxing (see http://java.sun.com/j2se/1.5.0/docs/guide/language/autoboxing.html) to compare directly with an int, so you can do:

if (count > 0) { }

And the Integer instance count gets automatically converted to an int for the comparison.

If you're having trouble understanding this, check out the link above, or imagine it's doing this:

if (count.intValue() > 0) { }

Basically both ArrayList and Vector both uses internal Object Array.

ArrayList: The ArrayList class extends AbstractList and implements the List interface and RandomAccess (marker interface). ArrayList supports dynamic arrays that can grow as needed. It gives us first iteration over elements. ArrayList uses internal Object Array; they are created with an default initial size of 10. When this size is exceeded, the collection is automatically increases to half of the default size that is 15.

Vector: Vector is similar to ArrayList but the differences are, it is synchronized and its default initial size is 10 and when the size exceeds its size increases to double of the original size that means the new size will be 20. Vector is the only class other than ArrayList to implement RandomAccess. Vector is having four constructors out of that one takes two parameters Vector(int initialCapacity, int capacityIncrement) capacityIncrement is the amount by which the capacity is increased when the vector overflows, so it have more control over the load factor.

Some other differences are:

Dirk's answer is good but if you need the sort to persist you'll want to apply the sort back onto the name of that data frame. Using the example code:

dd <- dd[with(dd, order(-z, b)), ] 

echo "this is the body" | mail -s "this is the subject" "to@address"

It seems strange, but nonetheless HTML5 supports drawing lines, circles, rectangles and many other basic shapes, it does not have anything suitable for drawing the basic point. The only way to do so is to simulate point with whatever you have.

So basically there are 3 possible solutions:

• draw point as a line
• draw point as a polygon
• draw point as a circle

Each of them has their drawbacks

Line

function point(x, y, canvas){
  canvas.beginPath();
  canvas.moveTo(x, y);
  canvas.lineTo(x+1, y+1);
  canvas.stroke();
}

Keep in mind that we are drawing to South-East direction, and if this is the edge, there can be a problem. But you can also draw in any other direction.

Rectangle

function point(x, y, canvas){
  canvas.strokeRect(x,y,1,1);
}

or in a faster way using fillRect because render engine will just fill one pixel.

function point(x, y, canvas){
  canvas.fillRect(x,y,1,1);
}

Circle

One of the problems with circles is that it is harder for an engine to render them

function point(x, y, canvas){
  canvas.beginPath();
  canvas.arc(x, y, 1, 0, 2 * Math.PI, true);
  canvas.stroke();
}

the same idea as with rectangle you can achieve with fill.

function point(x, y, canvas){
  canvas.beginPath();
  canvas.arc(x, y, 1, 0, 2 * Math.PI, true);
  canvas.fill();
}

Problems with all these solutions:

• it is hard to keep track of all the points you are going to draw.
• when you zoom in, it looks ugly.

If you are wondering, "What is the best way to draw a point?", I would go with filled rectangle. You can see my jsperf here with comparison tests.

var stringArray = ["String1", "String2", "String3"];

              .setMessage("Your Message")
              .setCancelable(false)
              .setPositiveButton("ok", new OnClickListener() {
                  @Override
                  public void onClick(DialogInterface dialog, int which) {
                      // Whatever...
                  }
              }).show();
        }
    }
});

This parses integers or strings to a target enum with partial matching in .NET 4.0 using generics like in Tawani's utility class. I am using it to convert command-line switch variables which may be incomplete. Since an enum cannot be null, you should logically provide a default value. It can be called like this:

var result = EnumParser<MyEnum>.Parse(valueToParse, MyEnum.FirstValue);

Here's the code:

using System;

public class EnumParser<T> where T : struct
{
    public static T Parse(int toParse, T defaultVal)
    {
        return Parse(toParse + "", defaultVal);
    }
    public static T Parse(string toParse, T defaultVal)
    {
        T enumVal = defaultVal;
        if (defaultVal is Enum && !String.IsNullOrEmpty(toParse))
        {
            int index;
            if (int.TryParse(toParse, out index))
            {
                Enum.TryParse(index + "", out enumVal);
            }
            else
            {
                if (!Enum.TryParse<T>(toParse + "", true, out enumVal))
                {
                    MatchPartialName(toParse, ref enumVal);
                }
            }
        }
        return enumVal;
    }

    public static void MatchPartialName(string toParse, ref T enumVal)
    {
        foreach (string member in enumVal.GetType().GetEnumNames())
        {
            if (member.ToLower().Contains(toParse.ToLower()))
            {
                if (Enum.TryParse<T>(member + "", out enumVal))
                {
                    break;
                }
            }
        }
    }
}

FYI: The question was about integers, which nobody mentioned will also explicitly convert in Enum.TryParse()

I've tried in a sample project to use standard, @2x and @3x images, and the iPhone 6+ simulator uses the @3x image. So it would seem that there are @3x images to be done (if the simulator actually replicates the device's behavior). But the strange thing is that all devices (simulators) seem to use this @3x image when it's on the project structure, iPhone 4S/iPhone 5 too.
The lack of communication from Apple on a potential @3x structure, while they ask developers to publish their iOS8 apps is quite confusing, especially when seeing those results on simulator.

**Edit from Apple's Website **: Also found this on the "What's new on iOS 8" section on Apple's developer space :

Support for a New Screen Scale The iPhone 6 Plus uses a new Retina HD display with a screen scale of 3.0. To provide the best possible experience on these devices, include new artwork designed for this screen scale. In Xcode 6, asset catalogs can include images at 1x, 2x, and 3x sizes; simply add the new image assets and iOS will choose the correct assets when running on an iPhone 6 Plus. The image loading behavior in iOS also recognizes an @3x suffix.

Still not understanding why all devices seem to load the @3x. Maybe it's because I'm using regular files and not xcassets ? Will try soon.

Edit after further testing : Ok it seems that iOS8 has a talk in this. When testing on an iOS 7.1 iPhone 5 simulator, it uses correctly the @2x image. But when launching the same on iOS 8 it uses the @3x on iPhone 5. Not sure if that's a wanted behavior or a mistake/bug in iOS8 GM or simulators in Xcode 6 though.

You could achieve this with an extra <span>:

HTML

<h2><span>Featured products</span></h2>
<h2><span>Here is a very long h2, and as you can see the line get too wide</span></h2>

CSS

h2 {
    position: relative;
}

h2 span {
    background-color: white;
    padding-right: 10px;
}

h2:after {
    content:"";
    position: absolute;
    bottom: 0;
    left: 0;
    right: 0;
    height: 0.5em;
    border-top: 1px solid black;
    z-index: -1;
}

http://jsfiddle.net/myajouri/pkm5r/

Another solution without the extra <span> but requires an overflow: hidden on the <h2>:

h2 {
    overflow: hidden;
}

h2:after {
    content:"";
    display: inline-block;
    height: 0.5em;
    vertical-align: bottom;
    width: 100%;
    margin-right: -100%;
    margin-left: 10px;
    border-top: 1px solid black;

Single command without ps variables when using JSON as body {lastName:"doe"} for POST api call:

Invoke-WebRequest -Headers @{"Authorization" = "Bearer N-1234ulmMGhsDsCAEAzmo1tChSsq323sIkk4Zq9"} `
                  -Method POST `
                  -Body (@{"lastName"="doe";}|ConvertTo-Json) `
                  -Uri https://api.dummy.com/getUsers `
                  -ContentType application/json

if grep -q SomeString "$File"; then
  Some Actions # SomeString was found
fi

You don't need [[ ]] here. Just run the command directly. Add -q option when you don't need the string displayed when it was found.

The grep command returns 0 or 1 in the exit code depending on the result of search. 0 if something was found; 1 otherwise.

$ echo hello | grep hi ; echo $?
1
$ echo hello | grep he ; echo $?
hello
0
$ echo hello | grep -q he ; echo $?
0

You can specify commands as an condition of if. If the command returns 0 in its exitcode that means that the condition is true; otherwise false.

$ if /bin/true; then echo that is true; fi
that is true
$ if /bin/false; then echo that is true; fi
$

As you can see you run here the programs directly. No additional [] or [[]].

  right: 0;
  width: auto; /* to keep proportions */
  height: auto; /* to keep proportions */
  max-width: 100%; /* not to stand out from div */
  max-height: 100%; /* not to stand out from div */
  margin: auto auto 0; /* position to bottom and center */
}

Important: This issue drove me crazy for a couple days and I couldn't figure out what was going on with my curl & openssl installations. I finally figured out that it was my intermediate certificate (in my case, GoDaddy) which was out of date. I went back to my godaddy SSL admin panel, downloaded the new intermediate certificate, and the issue disappeared.

I'm sure this is the issue for some of you.

Apparently, GoDaddy had changed their intermediate certificate at some point, due to scurity issues, as they now display this warning:

"Please be sure to use the new SHA-2 intermediate certificates included in your downloaded bundle."

Hope this helps some of you, because I was going nuts and this cleaned up the issue on ALL my servers.

Inside - Outside

• gravity arranges the content inside the view.
• layout_gravity arranges the view's position outside of itself.

Sometimes it helps to see a picture, too. The green and blue are TextViews and the other two background colors are LinearLayouts.

Notes

• The layout_gravity does not work for views in a RelativeLayout. Use it for views in a LinearLayout or FrameLayout. See my supplemental answer for more details.
• The view's width (or height) has to be greater than its content. Otherwise gravity won't have any effect. Thus, wrap_content and gravity are meaningless together.
• The view's width (or height) has to be less than the parent. Otherwise layout_gravity won't have any effect. Thus, match_parent and layout_gravity are meaningless together.
• The layout_gravity=center looks the same as layout_gravity=center_horizontal here because they are in a vertical linear layout. You can't center vertically in this case, so layout_gravity=center only centers horizontally.
• This answer only dealt with setting gravity and layout_gravity on the views within a layout. To see what happens when you set the gravity of the of the parent layout itself, check out the supplemental answer that I referred to above. (Summary: gravity doesn't work well on a RelativeLayout but can be useful with a LinearLayout.)

So remember, layout_gravity arranges a view in its layout. Gravity arranges the content inside the view.

• Match_parent vs wrap_content
• How to set both gravity and layout gravity of a LinearLayout programatically

You can look up an object's keys and values by either invoking JavaScript's native for in loop:

var obj = {
    foo:    'bar',
    base:   'ball'
};

for(var key in obj) {
    alert('key: ' + key + '\n' + 'value: ' + obj[key]);
}

or using jQuery's .each() method:

$.each(obj, function(key, element) {
    alert('key: ' + key + '\n' + 'value: ' + element);
});

With the exception of six primitive types, everything in ECMA-/JavaScript is an object. Arrays; functions; everything is an object. Even most of those primitives are actually also objects with a limited selection of methods. They are cast into objects under the hood, when required. To know the base class name, you may invoke the Object.prototype.toString method on an object, like this:

alert(Object.prototype.toString.call([]));

The above will output [object Array].

There are several other class names, like [object Object], [object Function], [object Date], [object String], [object Number], [object Array], and [object Regex].

session in rails is a hash object. Hence any function available for clearing hash will work with sessions.

session.clear

or if specific keys have to be destroyed:

session.delete(key)

Tested in rails 3.2

added

People have mentioned by session={} is a bad idea. Regarding session.clear, Lobati comments- It looks like you're probably better off using reset_session [than session.clear], as it does some other cleaning up beyond what session.clear does. Internally, reset_session calls session.destroy, which itself calls clear as well some other stuff.

Note if you are using typings do the following:

rm -r typings
typings install

If your doing the angular 2 tutorial use this:

rm -r typings
npm run postinstall
npm start

if the postinstall command dosen't work, try installing typings globally like so:

npm install -g typings

you can also try the following as opposed to postinstall:

typings install

and you should have this issue fixed!

I have spent some time trying to figure out the difference.

And i think the factory function uses the module pattern and service function uses the standard java script constructor pattern.

Just to give my 2 cents.

At this moment I also DO get the full user's local path. It's only from 1 machine that I can replicate this issue, but it really does give the full path of the file at the machine of the user.

This is a end-user of our application which is hosted on a off-site server. So it's not on the local machine nor on a local server from which it might happen to be a share.

You can resolve the issue, at least to have the same behaviour all the time by this:

Path.GetFileName(fileUpload.FileName)

Btw, just found this article which states it can happen too: http://www.eggheadcafe.com/community/aspnet/17/10092650/fileupload-control-pro.aspx

Just to confirm the issue.

You don't need the SELECT

DECLARE @LastChangeDate as date
SET @LastChangeDate = GetDate()

Define in html:

<input type="hidden" name="image" id="image"/>

In JS:

ajax.jsonRpc("/consulta/dni", 'call', {'document_number': document_number})
    .then(function (data) {
        if (data.error){
            ...;
        }
        else {
            $('#image').val(data.image);
        }
    })

After:

<input type="hidden" name="image" id="image" value="/9j/4AAQSkZJRgABAgAAAQABAAD/2wBDAAgGBgcGBQgHBwcJCQgKDBQNDAsLDBkSEw8U..."/>
<button type="submit">Submit</button>

opacity: 0.99; on wrapper solve webkit bug

You can use something like this.

$ cat test_file.txt
54 68 69 73 20 69 73 20 74 65 78 74 20 64 61 74 61 2e 0a 4f 6e 65 20 6d 6f 72 65 20 6c 69 6e 65 20 6f 66 20 74 65 73 74 20 64 61 74 61 2e

$ for c in `cat test_file.txt`; do printf "\x$c"; done;
This is text data.
One more line of test data.

The delete operator allows you to remove a property from an object.

The following examples all do the same thing.

// Example 1
var key = "Cow";
delete thisIsObject[key]; 

// Example 2
delete thisIsObject["Cow"];

// Example 3
delete thisIsObject.Cow;

If you're interested, read Understanding Delete for an in-depth explanation.

What is a patch?

A patch is little more (see below) than a series of instructions: "add this here", "remove that there", "change this third thing to a fourth". That's why git tells you:

The copy of the patch that failed is found in:
c:/.../project2/.git/rebase-apply/patch

You can open that patch in your favorite viewer or editor, open the files-to-be-changed in your favorite editor, and "hand apply" the patch, using what you know (and git does not) to figure out how "add this here" is to be done when the files-to-be-changed now look little or nothing like what they did when they were changed earlier, with those changes delivered to you as a patch.

A little more

A three-way merge introduces that "little more" information than the plain "series of instructions": it tells you what the original version of the file was as well. If your repository has the original version, your git can compare what you did to a file, to what the patch says to do to the file.

As you saw above, if you request the three-way merge, git can't find the "original version" in the other repository, so it can't even attempt the three-way merge. As a result you get no conflict markers, and you must do the patch-application by hand.

Using --reject

When you have to apply the patch by hand, it's still possible that git can apply most of the patch for you automatically and leave only a few pieces to the entity with the ability to reason about the code (or whatever it is that needs patching). Adding --reject tells git to do that, and leave the "inapplicable" parts of the patch in rejection files. If you use this option, you must still hand-apply each failing patch, and figure out what to do with the rejected portions.

Once you have made the required changes, you can git add the modified files and use git am --continue to tell git to commit the changes and move on to the next patch.

What if there's nothing to do?

Since we don't have your code, I can't tell if this is the case, but sometimes, you wind up with one of the patches saying things that amount to, e.g., "fix the spelling of a word on line 42" when the spelling there was already fixed.

In this particular case, you, having looked at the patch and the current code, should say to yourself: "aha, this patch should just be skipped entirely!" That's when you use the other advice git already printed:

If you prefer to skip this patch, run "git am --skip" instead.

If you run git am --skip, git will skip over that patch, so that if there were five patches in the mailbox, it will end up adding just four commits, instead of five (or three instead of five if you skip twice, and so on).

I used to use the easy_install pip==1.2.1 workaround but I randomly found that if you're having this bug, you probably installed a 32bit version of python on a 64bit machine.

In short : If you install a 64bit version of it by installing it from the source and then build your virtualenv upon it, you wont have that pip bug anymore.

Create a file called "SetFile.bat" that contains the following line with no carriage return at the end of it...

set FileContents=

Then in your batch file do something like this...

   @echo off
   copy SetFile.bat + %1 $tmp$.bat > nul
   call $tmp$.bat
   del $tmp$.bat

%1 is the name of your input file and %FileContents% will contain the contents of the input file after the call. This will only work on a one line file though (i.e. a file containing no carriage returns). You could strip out/replace carriage returns from the file before calling the %tmp%.bat if needed.

I prefer this,

List<String> temp = Arrays.asList(speciesArr);
species.addAll(temp);

The reason is Arrays.asList() method will create a fixed sized List. So if you directly store it into species then you will not be able to add any more element, still its not read-only. You can surely edit your items. So take it into temporary list.

Alternative for this is,

Collections.addAll(species, speciesArr);

In this case, you can add, edit, remove your items.

A possible solution:

document.getElementById("yourDatePicker").valueAsDate = new Date();

Using Moment.js:

var today = moment().format('YYYY-MM-DD');
document.getElementById("datePicker").value = today;

Using Spring context 5.0 I have successfully achieved loading correct property file based on system environment via the following annotation

@PropertySources({
    @PropertySource("classpath:application.properties"),
    @PropertySource("classpath:application-${MYENV:test}.properties")})

Here MYENV value is read from system environment and if system environment is not present then default test environment property file will be loaded, if I give a wrong MYENV value - it will fail to start the application.

Note: for each profile, you want to maintain - you will need to make an application-[profile].property file and although I used Spring context 5.0 & not Spring boot - I believe this will also work on Spring 4.1

You may want to take if from a diffrent side: It seems easier to have a TextView with a drawable on the background:

 <TextView
            android:id="@+id/text"
            android:background="@drawable/rounded_rectangle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
        </TextView>

to convert a TimestampTZ in oracle, you do

TO_TIMESTAMP_TZ('2012-10-09 1:10:21 CST','YYYY-MM-DD HH24:MI:SS TZR') 
  at time zone 'region'

Note in 2018: readAsBinaryString is outdated. For use cases where previously you'd have used it, these days you'd use readAsArrayBuffer (or in some cases, readAsDataURL) instead.

readAsBinaryString says that the data must be represented as a binary string, where:

...every byte is represented by an integer in the range [0..255].

JavaScript originally didn't have a "binary" type (until ECMAScript 5's WebGL support of Typed Array* (details below) -- it has been superseded by ECMAScript 2015's ArrayBuffer) and so they went with a String with the guarantee that no character stored in the String would be outside the range 0..255. (They could have gone with an array of Numbers instead, but they didn't; perhaps large Strings are more memory-efficient than large arrays of Numbers, since Numbers are floating-point.)

If you're reading a file that's mostly text in a western script (mostly English, for instance), then that string is going to look a lot like text. If you read a file with Unicode characters in it, you should notice a difference, since JavaScript strings are UTF-16** (details below) and so some characters will have values above 255, whereas a "binary string" according to the File API spec wouldn't have any values above 255 (you'd have two individual "characters" for the two bytes of the Unicode code point).

If you're reading a file that's not text at all (an image, perhaps), you'll probably still get a very similar result between readAsText and readAsBinaryString, but with readAsBinaryString you know that there won't be any attempt to interpret multi-byte sequences as characters. You don't know that if you use readAsText, because readAsText will use an encoding determination to try to figure out what the file's encoding is and then map it to JavaScript's UTF-16 strings.

You can see the effect if you create a file and store it in something other than ASCII or UTF-8. (In Windows you can do this via Notepad; the "Save As" as an encoding drop-down with "Unicode" on it, by which looking at the data they seem to mean UTF-16; I'm sure Mac OS and *nix editors have a similar feature.) Here's a page that dumps the result of reading a file both ways:

If I use that with a "Testing 1 2 3" file stored in UTF-16, here are the results I get:

Text (13):

54 65 73 74 69 6e 67 20 31 20 32 20 33

Binary (28):

ff fe 54 00 65 00 73 00 74 00 69 00 6e 00 67 00 20 00 31 00 20 00 32 00 20 00 33 00

As you can see, readAsText interpreted the characters and so I got 13 (the length of "Testing 1 2 3"), and readAsBinaryString didn't, and so I got 28 (the two-byte BOM plus two bytes for each character).

* XMLHttpRequest.response with responseType = "arraybuffer" is supported in HTML 5.

** "JavaScript strings are UTF-16" may seem like an odd statement; aren't they just Unicode? No, a JavaScript string is a series of UTF-16 code units; you see surrogate pairs as two individual JavaScript "characters" even though, in fact, the surrogate pair as a whole is just one character. See the link for details.

As karim79 mentioned, the first is the most concise. However I could argue that the second is more understandable as it is not obvious/known to some Javascript/jQuery programmers that non-zero/false values are evaluated to true in if-statements. And because of that, the third method is incorrect.

For me works fine:

@RequestMapping (value = "/{id}", method = RequestMethod.GET)
public ResponseEntity<Object> redirectToExternalUrl() throws URISyntaxException {
    URI uri = new URI("http://www.google.com");
    HttpHeaders httpHeaders = new HttpHeaders();
    httpHeaders.setLocation(uri);
    return new ResponseEntity<>(httpHeaders, HttpStatus.SEE_OTHER);
}

Javascript solution for your case:

console.log(unique(standardsList));

function unique(obj){
    var uniques=[];
    var stringify={};
    for(var i=0;i<obj.length;i++){
       var keys=Object.keys(obj[i]);
       keys.sort(function(a,b) {return a-b});
       var str='';
        for(var j=0;j<keys.length;j++){
           str+= JSON.stringify(keys[j]);
           str+= JSON.stringify(obj[i][keys[j]]);
        }
        if(!stringify.hasOwnProperty(str)){
            uniques.push(obj[i]);
            stringify[str]=true;
        }
    }
    return uniques;
}

There is also a shorthand of doing this:

NSArray *persons = @[person1, person2, person3];

It's equivalent to

NSArray *persons = [NSArray arrayWithObjects:person1, person2, person3, nil];

As iiFreeman said, you still need to do proper memory management if you're not using ARC.

strToLower's return type should be char* not char (or it should return nothing at all, since it doesn't re-allocate the string)

A readonly element is just not editable, but gets sent when the according form submits. A disabled element isn't editable and isn't sent on submit. Another difference is that readonly elements can be focused (and getting focused when "tabbing" through a form) while disabled elements can't.

Read more about this in this great article or the definition by w3c. To quote the important part:

Key Differences

The Disabled attribute

• Values for disabled form elements are not passed to the processor method. The W3C calls this a successful element.(This works similar to form check boxes that are not checked.)
• Some browsers may override or provide default styling for disabled form elements. (Gray out or emboss text) Internet Explorer 5.5 is particularly nasty about this.
• Disabled form elements do not receive focus.
• Disabled form elements are skipped in tabbing navigation.

The Read Only Attribute

• Not all form elements have a readonly attribute. Most notable, the <SELECT> , <OPTION> , and <BUTTON> elements do not have readonly attributes (although they both have disabled attributes)
• Browsers provide no default overridden visual feedback that the form element is read only. (This can be a problem… see below.)
• Form elements with the readonly attribute set will get passed to the form processor.
• Read only form elements can receive the focus
• Read only form elements are included in tabbed navigation.

PHP 5.2 introduced the filter_var function.

It supports a great deal of SANITIZE, VALIDATE filters.

Typedef allows items to be implicitly assigned to types they are not. Some people try to get around this with extensions; read here at IBM for an explanation of why this is a bad idea.

Edit: While strong type inference is a useful thing, I don't think (and hope we won't) see typedef rearing it's ugly head in managed languages (ever?).

Edit 2: In C#, you can use a using statement like this at the top of a source file. It's used so you don't have to do the second item shown. The only time you see the name change is when a scope introduces a name collision between two types. The renaming is limited to one file, outside of which every variable/parameter type which used it is known by its full name.

Since you've labeled the question C++, you might be interested in using boost::asio, ACE, or some other cross-platform socket library for C++ or for C. Some other cross-platform libraries may be found in the answers to C++ sockets library for cross-platform and Cross platform Networking API.

Assuming that using a third party cross-platform sockets library is not an option for you...

The header <sys/socket.h> is defined in IEEE Std. 1003.1 (POSIX), but sadly Windows is non-compliant with the POSIX standard. The MinGW compiler is a port of GCC for compiling Windows applications, and therefore does not include these POSIX system headers. If you install GCC using Cygwin, then it will include these system headers to emulate a POSIX environment on Windows. Be aware, however, that if you use Cygwin for sockets that a.) you will need to put the cygwin DLL in a place where your application can read it and b.) Cygwin headers and Windows headers don't interact very well (so if you plan on including windows.h, then you probably don't want to be including sys/socket.h).

My personal recommendation would be to download a copy of VirtualBox, download a copy of Ubuntu, install Ubuntu into VirtualBox, and then do your coding and testing on Ubuntu. Alternatively, I am told that Microsoft sells a "UNIX subsystem" and that it is pre-installed on certain higher-end editions of Windows, although I have no idea how compliant this system is (and, if it is compliant, with which edition of the UNIX standard it is compliant). Winsockets are also an option, although they can behave in subtly different ways than their POSIX counterparts, even though the signatures may be similar.

File modification:

ls -t

Inode change:

ls -tc

File access:

ls -tu

"Newest" one at the bottom:

None of this is a creation time. Most Unix filesystems don't support creation timestamps.

Yes, it is possible.

There is a perfect open-source Python (.PYC) decompiler, called Decompyle++ https://github.com/zrax/pycdc/

Decompyle++ aims to translate compiled Python byte-code back into valid and human-readable Python source code. While other projects have achieved this with varied success, Decompyle++ is unique in that it seeks to support byte-code from any version of Python.

ES6 of the day here;

const json_getAllKeys = data => (
  data.reduce((keys, obj) => (
    keys.concat(Object.keys(obj).filter(key => (
      keys.indexOf(key) === -1))
    )
  ), [])
)

And yes it can be written in very long one line;

const json_getAllKeys = data => data.reduce((keys, obj) => keys.concat(Object.keys(obj).filter(key => keys.indexOf(key) === -1)), [])

EDIT: Returns all first order keys if the input is of type array of objects

Because of the GDPR it makes no sense to use the iframe, you should rather use the object tag with the embed tag and also use the embed link.

<object width="100%" height="333">
  <param name="movie" value="https://www.youtube-nocookie.com/embed/Sdg0ef2PpBw">
  <embed src="https://www.youtube-nocookie.com/embed/Sdg0ef2PpBw" width="100%" height="333">
</object>

You should also activate the extended data protection mode function to receive the no cookie url.

type="application/x-shockwave-flash" 

flash does not have to be used

Nocookie, however, means that data is still being transmitted, namely the thumbnail that is loaded from YouTube. But at least data is no longer passed on to advertising networks (as example DoubleClick). And no user data is stored on your website by youtube.

Here is the same function that @BrunoLM posted converted to a String prototype function:

String.prototype.getBytes = function () {
  var bytes = [];
  for (var i = 0; i < this.length; ++i) {
    bytes.push(this.charCodeAt(i));
  }
  return bytes;
};

If you define the function as such, then you can call the .getBytes() method on any string:

var str = "Hello World!";
var bytes = str.getBytes();

@Autowired can be used with setters so you could have a setter modifying an static field.

Just one final suggestion... DON'T

Sure you can.

ALTER TABLE myTable ALTER COLUMN myColumn int NULL

Just substitute int for whatever datatype your column is.

Code to get contact name (Ascending order) and number

For more reference: show contact in listview

Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" ASC");
        while (phones.moveToNext())
        {
            String name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
            String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));


        }
        phones.close();

If you look at the code for the component you can see that it uses the className prop passed to it to combine with the row class to get the resulting set of classes (<Row className="aaa bbb"... works).Also, if you provide the id prop like <Row id="444" ... it will actually set the id attribute for the element.

Did you try export directive of Make itself (assuming that you use GNU Make)?

export PATH := bin:$(PATH)

test all:
    x

Also, there is a bug in you example:

test all:
    PATH=bin:${PATH}
    @echo $(PATH)
    x

First, the value being echoed is an expansion of PATH variable performed by Make, not the shell. If it prints the expected value then, I guess, you've set PATH variable somewhere earlier in your Makefile, or in a shell that invoked Make. To prevent such behavior you should escape dollars:

test all:
    PATH=bin:$$PATH
    @echo $$PATH
    x

Second, in any case this won't work because Make executes each line of the recipe in a separate shell. This can be changed by writing the recipe in a single line:

test all:
    export PATH=bin:$$PATH; echo $$PATH; x

The accepted answer didn't work in my situation, not sure why. I switched from JRE1.7 to JRE1.8 and that resolved the issue automatically. JRE1.8 uses TLS1.2 by default

Use Bootstrap FileStyle, which is used to style the file fields of forms. It is a plugin for a jQuery-based component library called Twitter Bootstrap

Sample usage:

Include:

<script type="text/javascript" src="js/bootstrap-filestyle.min.js"> </script>

Via JavaScript:

$(":file").filestyle();

Via data attributes:

<input type="file" class="filestyle" data-classButton="btn btn-primary" data-input="false" data-classIcon="icon-plus" data-buttonText="Your label here.">

The image needs to be in the same folder that your html page is in, then create a href to that folder with the picture name at the end. Example:

<img src="C:\users\home\pictures\picture.png"/>

This is the one symptom of greater issues. Notably that you have something setting TERM=dumb. Other things that don't work properly are the less command which says you don't have a fully functional terminal.

It seems like this is most commonly caused by having TERM set to something in your global Windows environment variables. For me, the issue came up when I installed Strawberry Perl some information about this is on the msysgit bug for this problem as well as several solutions.

The first solution is to fix it in your ~/.bashrc by adding:

export TERM=msys

You can do this from the Git Bash prompt like so:

echo "export TERM=msys" >> ~/.bashrc

The other solution, which ultimately is what I did because I don't care about Strawberry Perl's reasons for adding TERM=dumb to my environment settings, is to go and remove the TERM=dumb as directed in this comment on the msysgit bug report.

Control Panel/System/Advanced/Environment Variables... (or similar, depending on your version of Windows) is where sticky environment variables are set on Windows. By default, TERM is not set. If TERM is set in there, then you (or one of the programs you have installed - e.g. Strawberry Perl) has set it. Delete that setting, and you should be fine.

Similarly if you use Strawberry Perl and care about the CPAN client or something like that, you can leave the TERM=dumb alone and use unset TERM in your ~/.bashrc file which will have a similar effect to setting an explicit term as above.

Of course, all the other solutions are correct in that you can use git config --global core.editor $MYFAVORITEEDITOR to make sure that Git uses your favorite editor when it needs to launch one for you.

It could be caused by a data conversion from .NET to SQL, for instance a datetime conversion error. For me it was a null reference to a datetime column.

Also, that is not an exact error message. You can see the exact error in watch at exception.InnerException.InnerException -> ResultView.

I am getting fast queries (around 0.5 seconds) with a slow cpu, selecting 10 random rows in a 400K registers MySQL database non-cached 2Gb size. See here my code: Fast selection of random rows in MySQL

$time= microtime_float();

$sql='SELECT COUNT(*) FROM pages';
$rquery= BD_Ejecutar($sql);
list($num_records)=mysql_fetch_row($rquery);
mysql_free_result($rquery);

$sql="SELECT id FROM pages WHERE RAND()*$num_records<20
   ORDER BY RAND() LIMIT 0,10";
$rquery= BD_Ejecutar($sql);
while(list($id)=mysql_fetch_row($rquery)){
    if($id_in) $id_in.=",$id";
    else $id_in="$id";
}
mysql_free_result($rquery);

$sql="SELECT id,url FROM pages WHERE id IN($id_in)";
$rquery= BD_Ejecutar($sql);
while(list($id,$url)=mysql_fetch_row($rquery)){
    logger("$id, $url",1);
}
mysql_free_result($rquery);

$time= microtime_float()-$time;

logger("num_records=$num_records",1);
logger("$id_in",1);
logger("Time elapsed: <b>$time segundos</b>",1);

The Simple Difference is: console.log() methods automatically append new line character. It means if we are looping through and printing the result, each result get printed in new line.

process.stdout.write() methods don't append new line character. useful for printing patterns.

According to the stack trace, your issue is that your app cannot find org.apache.commons.dbcp.BasicDataSource, as per this line:

java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource

I see that you have commons-dbcp in your list of jars, but for whatever reason, your app is not finding the BasicDataSource class in it.

None of these answers seemed simple enough - the crux of the problem is not having to rebuild:

makefile

OBJDIR=out
VPATH=$(OBJDIR)

# make will look in VPATH to see if the target needs to be rebuilt
test: moo
    touch $(OBJDIR)/$@

example use

touch moo
# creates out/test
make test
# doesn't update out/test
make test
# will now update test
touch moo
make test

To select the 2nd option

$('#your-select-box-id :nth-child(2)').prop('selected', true);

Here we add the `trigger('change') to make the event fire.

$('#your-select-box-id :nth-child(2)').prop('selected', true).trigger('change');

In the Rails console, the variable app holds a session object on which you can call path and URL helpers as instance methods.

app.users_path

See,

There are two ways to convert an RDD to DF in Spark.

toDF() and createDataFrame(rdd, schema)

I will show you how you can do that dynamically.

toDF()

The toDF() command gives you the way to convert an RDD[Row] to a Dataframe. The point is, the object Row() can receive a **kwargs argument. So, there is an easy way to do that.

from pyspark.sql.types import Row

#here you are going to create a function
def f(x):
    d = {}
    for i in range(len(x)):
        d[str(i)] = x[i]
    return d

#Now populate that
df = rdd.map(lambda x: Row(**f(x))).toDF()

This way you are going to be able to create a dataframe dynamically.

createDataFrame(rdd, schema)

Other way to do that is creating a dynamic schema. How?

This way:

from pyspark.sql.types import StructType
from pyspark.sql.types import StructField
from pyspark.sql.types import StringType

schema = StructType([StructField(str(i), StringType(), True) for i in range(32)])

df = sqlContext.createDataFrame(rdd, schema)

This second way is cleaner to do that...

So this is how you can create dataframes dynamically.

In C++ copying the object means cloning. There is no any special cloning in the language.

As the standard suggests, after copying you should have 2 identical copies of the same object.

There are 2 types of copying: copy constructor when you create object on a non initialized space and copy operator where you need to release the old state of the object (that is expected to be valid) before setting the new state.

for(File f : files) {
    f.delete();
}    
files.delete(); // will work

Remember to include System.Diagnostics

ProcessStartInfo startInfo = new ProcessStartInfo("myfile.exe");        // exe file
startInfo.WorkingDirectory = @"C:\..\MyFile\bin\Debug\netcoreapp3.1\"; // exe folder

//here you add your arguments
startInfo.ArgumentList.Add("arg0");       // First argument          
startInfo.ArgumentList.Add("arg2");       // second argument
startInfo.ArgumentList.Add("arg3");       // third argument
Process.Start(startInfo);                 

In your router.php file, you should use the model class like this

 use App\Post;

and use the model class like this.

Route::get('/posts', function() {

        $results = Post::all();
        return $results; });

Actually you don't have to create an image at all. drawImage() will accept a Canvas as well as an Image object.

//grab the context from your destination canvas
var destCtx = destinationCanvas.getContext('2d');

//call its drawImage() function passing it the source canvas directly
destCtx.drawImage(sourceCanvas, 0, 0);

Way faster than using an ImageData object or Image element.

Note that sourceCanvas can be a HTMLImageElement, HTMLVideoElement, or a HTMLCanvasElement. As mentioned by Dave in a comment below this answer, you cannot use a canvas drawing context as your source. If you have a canvas drawing context instead of the canvas element it was created from, there is a reference to the original canvas element on the context under context.canvas.

Here is a jsPerf to demonstrate why this is the only right way to clone a canvas: http://jsperf.com/copying-a-canvas-element

For more advanced GET/POST requests, you can install the CURL library (http://us3.php.net/curl):

$ch = curl_init("REMOTE XML FILE URL GOES HERE"); // such as http://example.com/example.xml
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
$data = curl_exec($ch);
curl_close($ch);

In my case, I had accidentally named a folder 'samples '. I couldn't see the space when I did 'ls -la'.

Eventually I realized this when I tried tabbing to autocomplete and saw 'samples\ /'.

To fix this I ran

mv samples\  samples

I was working around with my shell script which need to do some path joining stuff like you do.

The thing is, both path like

/data/foo/bar

/data/foo/bar/ 

are valid.

If I want to append a file to this path like

/data/foo/bar/myfile

there was no native method (like os.path.join() in python) in shell to handle such situation.

But I did found a trick

For example , the base path was store in a shell variable

BASE=~/mydir

and the last file name you wanna join was

FILE=myfile

Then you can assign your new path like this

NEW_PATH=$(realpath ${BASE})/FILE

and then you`ll get

$ echo $NEW_PATH

/path/to/your/home/mydir/myfile

the reason is quiet simple, the "realpath" command would always trim the terminating slash for you if necessary

use style white-space: pre the <pre> tag also modifies the text format which may be undesirable.

It's a very difficult problem to validate something like a name due to all the corner cases possible.

Corner Cases

• Anything anything here

Sanitize the inputs and let them enter whatever they want for a name, because deciding what is a valid name and what is not is probably way outside the scope of whatever you're doing; given the range of potential strange - and legal names is nearly infinite.

If they want to call themselves Tricyclopltz^2-Glockenschpiel, that's their problem, not yours.

Change localhost:8080 to localhost:3306.

No, there isn't.

I'm pretty sure there is no way to intercept a click on the refresh button from JS, and even if there was, JS can be turned off.

You should probably step back from your X (preventing refreshing) and find a different solution to Y (whatever that might be).

The below code works well for me (at least for Chrome).

I also added some margin and page orientation controls.(portrait, landscape)

<style type="text/css" media="print">
@media print {
  body {-webkit-print-color-adjust: exact;}
}
@page {
    size:A4 landscape;
    margin-left: 0px;
    margin-right: 0px;
    margin-top: 0px;
    margin-bottom: 0px;
    margin: 0;
    -webkit-print-color-adjust: exact;
}
</style>

For me the issue was that the maven sonar plugin was using proxy servers defined in the maven settings.xml. I was trying to access the sonarque on another (not localhost alias) and so it was trying to use the proxy server to access it. Just added my alias to nonProxyHosts in settings.xml and it is working now. I did not face this issue in maven sonar plugin 3.2, only after i upgraded it.

In my rails (rails 4.2) project, I use

and it works.

There are three types of allocation — static, automatic, and dynamic.

Static Allocation means, that the memory for your variables is allocated when the program starts. The size is fixed when the program is created. It applies to global variables, file scope variables, and variables qualified with static defined inside functions.

Automatic memory allocation occurs for (non-static) variables defined inside functions, and is usually stored on the stack (though the C standard doesn't mandate that a stack is used). You do not have to reserve extra memory using them, but on the other hand, have also limited control over the lifetime of this memory. E.g: automatic variables in a function are only there until the function finishes.

void func() {
    int i; /* `i` only exists during `func` */
}

Dynamic memory allocation is a bit different. You now control the exact size and the lifetime of these memory locations. If you don't free it, you'll run into memory leaks, which may cause your application to crash, since at some point of time, system cannot allocate more memory.

int* func() {
    int* mem = malloc(1024);
    return mem;
}

int* mem = func(); /* still accessible */

In the upper example, the allocated memory is still valid and accessible, even though the function terminated. When you are done with the memory, you have to free it:

free(mem);

Lea's converter is no longer available. I just used this converter

Steps:

1. Enter the Unicode decimal version such as 8226 in the tool's green input field.
2. Press Dec code points
3. See the result in the box Unicode U+hex notation (eg U+2022)
4. Use it in your CSS. Eg content: '\2022'

All other answers sounds good, I would like to cover my case, where I had to make an animated LaunchScreen, then after 3 to 4 seconds of animation the next task was to move to Home screen. I tried segues, but that created problem for destination view. So at the end I accessed AppDelegates's Window property and I assigned a new NavigationController screen to it,

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let appDelegate = UIApplication.shared.delegate as! AppDelegate
let homeVC = storyboard.instantiateViewController(withIdentifier: "HomePageViewController") as! HomePageViewController

//Below's navigationController is useful if u want NavigationController in the destination View
let navigationController = UINavigationController(rootViewController: homeVC)
appDelegate.window!.rootViewController = navigationController

If incase, u don't want navigationController in the destination view then just assign as,

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let appDelegate = UIApplication.shared.delegate as! AppDelegate
let homeVC = storyboard.instantiateViewController(withIdentifier: "HomePageViewController") as! HomePageViewController
appDelegate.window!.rootViewController = homeVC

If you need Jenkins to access more then 1 project you will need to:
1. add public key to one github user account
2. add this user as Owner (to access all projects) or as a Collaborator in every project.

Many public keys for one system user will not work because GitHub will find first matched deploy key and will send back error like "ERROR: Permission to user/repo2 denied to user/repo1"

Use Minted.

It's a package that facilitates expressive syntax highlighting in LaTeX using the powerful Pygments library. The package also provides options to customize the highlighted source code output using fancyvrb.

It's much more evolved and customizable than any other package!

The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date') declare the date property like so: private _date: string;. Also, make sure you are instantiating the model with the new keyword. Lastly, access the property using regular dot notation.

Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :

let passcode = "secret passcode";

class Employee {
    private _fullName: string;

    get fullName(): string {
        return this._fullName;
    }

    set fullName(newName: string) {
        if (passcode && passcode == "secret passcode") {
            this._fullName = newName;
        }
        else {
            console.log("Error: Unauthorized update of employee!");
        }
    }
}

let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
    console.log(employee.fullName);
}

And here is a plunker demonstrating what it sounds like you're trying to do: https://plnkr.co/edit/OUoD5J1lfO6bIeME9N0F?p=preview

double quotes worked in oracle when I had the keyword as one of the column name.

The reason that the performance of instanceof and getClass() == ... is different is that they are doing different things.

• instanceof tests whether the object reference on the left-hand side (LHS) is an instance of the type on the right-hand side (RHS) or some subtype.

• getClass() == ... tests whether the types are identical.

So the recommendation is to ignore the performance issue and use the alternative that gives you the answer that you need.

Is using the instanceOf operator bad practice ?

Not necessarily. Overuse of either instanceOf or getClass() may be "design smell". If you are not careful, you end up with a design where the addition of new subclasses results in a significant amount of code reworking. In most situations, the preferred approach is to use polymorphism.

However, there are cases where these are NOT "design smell". For example, in equals(Object) you need to test the actual type of the argument, and return false if it doesn't match. This is best done using getClass().

^{Terms like "best practice", "bad practice", "design smell", "antipattern" and so on should be used sparingly and treated with suspicion. They encourage black-or-white thinking. It is better to make your judgements in context, rather than based purely on dogma; e.g. something that someone said is "best practice". I recommend that everyone read No Best Practices if they haven't already done so.}

val : must add or initialized value but can't change. var: it's variable can ba change in any line in code.

Take a look at the log_errors configuration option in php.ini. It seems to do just what you want to. I think you can use the error_log option to set your own logging file too.

When the log_errors directive is set to On, any errors reported by PHP would be logged to the server log or the file specified with error_log. You can set these options with ini_set too, if you need to.

(Please note that display_errors should be disabled in php.ini if this option is enabled)

There are 2 possibilities.

You really don't have Label property.

You need to call appropriate GetProperty overload and pass the correct binding flags, e.g. BindingFlags.Public | BindingFlags.Instance

If your property is not public, you will need to use BindingFlags.NonPublic or some other combination of flags which fits your use case. Read the referenced API docs to find the details.

EDIT:

ooops, just noticed you call GetProperty on typeof(MyClass). typeof(MyClass) is Type which for sure has no Label property.

I've worked it out.

Let's say you have a Python datetime object, d, created with datetime.now(). Its value is:

datetime.datetime(2011, 5, 25, 13, 34, 5, 787000)

You can serialize it to JSON as an ISO 8601 datetime string:

import json    
json.dumps(d.isoformat())

The example datetime object would be serialized as:

'"2011-05-25T13:34:05.787000"'

This value, once received in the Javascript layer, can construct a Date object:

var d = new Date("2011-05-25T13:34:05.787000");

As of Javascript 1.8.5, Date objects have a toJSON method, which returns a string in a standard format. To serialize the above Javascript object back to JSON, therefore, the command would be:

d.toJSON()

Which would give you:

'2011-05-25T20:34:05.787Z'

This string, once received in Python, could be deserialized back to a datetime object:

datetime.strptime('2011-05-25T20:34:05.787Z', '%Y-%m-%dT%H:%M:%S.%fZ')

This results in the following datetime object, which is the same one you started with and therefore correct:

datetime.datetime(2011, 5, 25, 20, 34, 5, 787000)

If at any point you return Promise.reject('something') you will be thrown in the catch block to the promise.

promiseOne
  .then((result) => {
    if (!result) {
      return Promise.reject('No result');
    }
    return;
  })
  .catch((err) => {
    console.log(err);
  });

If the first promise does not return any result you will only get 'No result' in the console.

I know I'm late :) But this how i do it:

public static void AddOrUpdateAppSettings(string key, string value)
{
    try
    {
        var configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        var settings = configFile.AppSettings.Settings;
        if (settings[key] == null)
        {
            settings.Add(key, value);
        }
        else
        {
            settings[key].Value = value;
        }
        configFile.Save(ConfigurationSaveMode.Modified);
        ConfigurationManager.RefreshSection(configFile.AppSettings.SectionInformation.Name);
    }
    catch (ConfigurationErrorsException)
    {
        Console.WriteLine("Error writing app settings");
    }
}

Adding to Dilips's answer, if you are working with JDK 9, use the following (my JDK version is 9.0.4) in Step # 3:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-9.0.4.jdk/Contents/Home

Edit: As of February, 2020, there's now a first-class UI for automatically mounting Drive.

First, open the file browser on the left hand side. It will show a 'Mount Drive' button. Once clicked, you'll see a permissions prompt to mount Drive, and afterwards your Drive files will be present with no setup when you return to the notebook. The completed flow looks like so:

The original answer follows, below. (This will also still work for shared notebooks.)

You can mount your Google Drive files by running the following code snippet:

from google.colab import drive
drive.mount('/content/drive')

Then, you can interact with your Drive files in the file browser side panel or using command-line utilities.

Here's an example notebook

By setting script tag type other than text/javascript, browser will not execute the internal code of script tag. This is called micro template. This concept is widely used in Single page application(aka SPA).

<script type="text/template">I am a Micro template. 
  I am going to make your web page faster.</script>

For micro template, type of the script tag is text/template. It is very well explained by Jquery creator John Resig http://ejohn.org/blog/javascript-micro-templating/
