For canvas in Chrome (Version 52)

All listed answers is about images. But my issue is about canvas in chrome (v.52) with transform rotate. They became jagged and all this methods can't help.

Solution that works for me:

1. Make canvas larger on 1 px for each side => +2 px for width and height;
2. Draw image with offset + 1px (in position 1,1 instead of 0,0) and fixed size (size of image should be 2px less than size of canvas)
3. Apply required rotation

So important code blocks:

// Unfixed version
ctx.drawImage(img, 0, 0, 335, 218);
// Fixed version
ctx.drawImage(img, 1, 1, 335, 218);

/* This style should be applied for fixed version */
canvas {
  margin-left: -1px;
  margin-top:-1px;
}        

<!--Unfixed version-->
<canvas width="335" height="218"></canvas>
<!--Fixed version-->
<canvas width="337" height="220"></canvas>

Sample: https://jsfiddle.net/tLbxgusx/1/

Note: there is a lot of nested divs because it is simplified version from my project.

This issue is reproduced also for Firefox for me. There is no such issue on Safari and FF with retina.

And other founded solution is to place canvas into div of same size and apply following css to this div:

overflow: hidden;
box-shadow: 0 0 1px rgba(255,255,255,0);
// Or
//outline:1px solid transparent;

And rotation should be applied to this wrapping div. So listed solution is worked but with small modification.

And modified example for such solution is: https://jsfiddle.net/tLbxgusx/2/

Note: See style of div with class 'third'.

here you go Sir :-)

1

.myElement{
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    text-rendering: optimizeLegibility;
}

2

.myElement{
    text-shadow: rgba(0,0,0,.01) 0 0 1px;
}

I found the solution with this link : http://pixelsvsbytes.com/blog/2013/02/nice-web-fonts-for-every-browser/

Step by step method :

• send your font to a WebFontGenerator and get the zip
• find the TTF font on the Zip file
• then, on linux, do this command (or install by apt-get install ttfautohint):
  ttfautohint --strong-stem-width=g neosansstd-black.ttf neosansstd-black.changed.ttf
• then, one more, send the new TTF file (neosansstd-black.changed.ttf) on the WebFontGenerator
• you get a perfect Zip with all your webfonts !

I hope this will help.

It's now 2018, and we finally have cheap ways to do something around it...

Indeed, since the 2d context API now has a filter property, and that this filter property can accept SVGFilters, we can build an SVGFilter that will keep only fully opaque pixels from our drawings, and thus eliminate the default anti-aliasing.

So it won't deactivate antialiasing per se, but provides a cheap way both in term of implementation and of performances to remove all semi-transparent pixels while drawing.

I am not really a specialist of SVGFilters, so there might be a better way of doing it, but for the example, I'll use a <feComponentTransfer> node to grab only fully opaque pixels.

var ctx = canvas.getContext('2d');_x000D_
ctx.fillStyle = '#ABEDBE';_x000D_
ctx.fillRect(0,0,canvas.width,canvas.height);_x000D_
ctx.fillStyle = 'black';_x000D_
ctx.font = '14px sans-serif';_x000D_
ctx.textAlign = 'center';_x000D_
_x000D_
// first without filter_x000D_
ctx.fillText('no filter', 60, 20);_x000D_
drawArc();_x000D_
drawTriangle();_x000D_
// then with filter_x000D_
ctx.setTransform(1, 0, 0, 1, 120, 0);_x000D_
ctx.filter = 'url(#remove-alpha)';_x000D_
// and do the same ops_x000D_
ctx.fillText('no alpha', 60, 20);_x000D_
drawArc();_x000D_
drawTriangle();_x000D_
_x000D_
// to remove the filter_x000D_
ctx.filter = 'none';_x000D_
_x000D_
_x000D_
function drawArc() {_x000D_
  ctx.beginPath();_x000D_
  ctx.arc(60, 80, 50, 0, Math.PI * 2);_x000D_
  ctx.stroke();_x000D_
}_x000D_
_x000D_
function drawTriangle() {_x000D_
  ctx.beginPath();_x000D_
  ctx.moveTo(60, 150);_x000D_
  ctx.lineTo(110, 230);_x000D_
  ctx.lineTo(10, 230);_x000D_
  ctx.closePath();_x000D_
  ctx.stroke();_x000D_
}_x000D_
// unrelated_x000D_
// simply to show a zoomed-in version_x000D_
var zCtx = zoomed.getContext('2d');_x000D_
zCtx.imageSmoothingEnabled = false;_x000D_
canvas.onmousemove = function drawToZoommed(e) {_x000D_
  var x = e.pageX - this.offsetLeft,_x000D_
    y = e.pageY - this.offsetTop,_x000D_
    w = this.width,_x000D_
    h = this.height;_x000D_
    _x000D_
  zCtx.clearRect(0,0,w,h);_x000D_
  zCtx.drawImage(this, x-w/6,y-h/6,w, h, 0,0,w*3, h*3);_x000D_
}

<svg width="0" height="0" style="position:absolute;z-index:-1;">_x000D_
  <defs>_x000D_
    <filter id="remove-alpha" x="0" y="0" width="100%" height="100%">_x000D_
      <feComponentTransfer>_x000D_
        <feFuncA type="discrete" tableValues="0 1"></feFuncA>_x000D_
      </feComponentTransfer>_x000D_
      </filter>_x000D_
  </defs>_x000D_
</svg>_x000D_
_x000D_
<canvas id="canvas" width="250" height="250" ></canvas>_x000D_
<canvas id="zoomed" width="250" height="250" ></canvas>

And for the ones that don't like to append an <svg> element in their DOM, you can also save it as an external svg file and set the filter property to path/to/svg_file.svg#remove-alpha.

I wasn't able to get Surya's and Matteo's solutions to work. For example, "(#f1)" was just displayed as text, and didn't become a link. However, their solutions led me to slightly different solution. (I also formatted the footnote and the link back to the original superscript a bit differently.)

In the body of the text:

Yadda yadda<a href="#note1" id="note1ref"><sup>1</sup></a>

At the end of the document:

<a id="note1" href="#note1ref"><sup>1</sup></a>Here is the footnote text.

Clicking on the superscript in the footnote returns to the superscript in the original text.

I also think having a separate "version" for normal execution and as a service is the way to go, but is it really required to dedicate a separate command line switch for that purpose?

Couldn't you just do:

public static int Main(string[] args)
{
  if (!Environment.UserInteractive)
  {
    // Startup as service.
  }
  else
  {
    // Startup as application
  }
}

That would have the "benefit", that you can just start your app via doubleclick (OK, if you really need that) and that you can just hit F5 in Visual Studio (without the need to modify the project settings to include that /console Option).

Technically, the Environment.UserInteractive checks if the WSF_VISIBLE Flag is set for the current window station, but is there any other reason where it would return false, apart from being run as a (non-interactive) service?

INADDR_ANY is used when you don't need to bind a socket to a specific IP. When you use this value as the address when calling bind(), the socket accepts connections to all the IPs of the machine.

Add to the div style:

width: fit-content;

Here's the basic approach,

DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");

Date beginDate = dateFormat.parse("2013-11-29");
Date endDate = dateFormat.parse("2013-12-4");

Calendar beginCalendar = Calendar.getInstance();
beginCalendar.setTime(beginDate);

Calendar endCalendar = Calendar.getInstance();
endCalendar.setTime(endDate);

There is simple way to implement it. We can use Calendar.add method with loop. The minus days between beginDate and endDate, and the implemented code as below,

int minusDays = 0;
while (true) {
  minusDays++;

  // Day increasing by 1
  beginCalendar.add(Calendar.DAY_OF_MONTH, 1);

  if (dateFormat.format(beginCalendar.getTime()).
            equals(dateFormat.format(endCalendar).getTime())) {
    break;
  }
}
System.out.println("The subtraction between two days is " + (minusDays + 1));**

If you use <img> tags, then webkit based browsers won't display embedded bitmapped images.

For any kind of advanced SVG use, including the SVG inline offers by far the most flexibility.

Internet Explorer and Edge will resize the SVG correctly, but you must specify both the height and width.

You can add onclick, onmouseover, etc. inside the svg, to any shape in the SVG: onmouseover="top.myfunction(evt);"

You can also use web fonts in the SVG by including them in your regular style sheet.

Note: if you are exporting SVG's from Illustrator, the web font names will be wrong. You can correct this in your CSS and avoid messing around in the SVG. For example, Illustrator gives the wrong name to Arial, and you can fix it like this:

@font-face {    
    font-family: 'ArialMT';    
    src:    
        local('Arial'),    
        local('Arial MT'),    
        local('Arial Regular');    
    font-weight: normal;    
    font-style: normal;    
}

All this works on any browser released since 2013.

For an example, see ozake.com. The whole site is made of SVG's except for the contact form.

Warning: Web fonts are imprecisely resized in Safari — and if you have lots of transitions from plain text to bold or italic, there may be a small amount of extra or missing space at the transition points. See my answer at this question for more information.

I wrote an add-on to overcome this issue in Firefox (Chrome, Opera version will have soon). It works with the latest Firefox version, with beautiful UI and support JS regex: https://addons.mozilla.org/en-US/firefox/addon/cross-domain-cors

In XML file, you need to add following additional attributes in a TextView to get a marquee like feature:

android:ellipsize="marquee"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:singleLine="true"

In MainActivity.java file, you can get the reference of this TextView by using findViewById() and you can set the following property to this TextView to make it appear like a marquee text:

setSelected(true);

That's all you need.

<%: 
     Html.DropDownListFor(
           model => model.Color, 
           new SelectList(
                  new List<Object>{ 
                       new { value = 0 , text = "Red"  },
                       new { value = 1 , text = "Blue" },
                       new { value = 2 , text = "Green"}
                    },
                  "value",
                  "text",
                   Model.Color
           )
        )
%>

or you can write no classes, put something like this directly to the view.

A slight change to Thangamani Palanisamy answer, which allows the Binary reader to be disposed and corrects the input length issue in his comments.

string result = string.Empty;

using (BinaryReader b = new BinaryReader(file.InputStream))
{
  byte[] binData = b.ReadBytes(file.ContentLength);
  result = System.Text.Encoding.UTF8.GetString(binData);
}

Evaluate might suit:

Thing is, the code you provided won't work because the <iframe> element has to have a "src" property, like:

<iframe id="uploads" src="http://domain/page.html"></iframe>

It's ok to use .contents() to get the content:

$('#uploads).contents() will give you access to the second iframe, but if that iframe is "INSIDE" the http://domain/page.html document the #uploads iframe loaded.

To test I'm right about this, I created 3 html files named main.html, iframe.html and noframe.html and then selected the div#element just fine with:

$('#uploads').contents().find('iframe').contents().find('#element');

There WILL be a delay in which the element will not be available since you need to wait for the iframe to load the resource. Also, all iframes have to be on the same domain.

Hope this helps ...

Here goes the html for the 3 files I used (replace the "src" attributes with your domain and url):

main.html

<!DOCTYPE HTML>
<html>
<head>
    <meta charset="utf-8">
    <title>main.html example</title>

    <script>
        $(function () {
            console.log( $('#uploads').contents().find('iframe').contents().find('#element') ); // nothing at first

            setTimeout( function () {
                console.log( $('#uploads').contents().find('iframe').contents().find('#element') ); // wait and you'll have it
            }, 2000 );

        });

From The Little MongoDB Book

Yet another alternative to using joins is to denormalize your data. Historically, denormalization was reserved for performance-sensitive code, or when data should be snapshotted (like in an audit log). However, with the ever- growing popularity of NoSQL, many of which don’t have joins, denormalization as part of normal modeling is becoming increasingly common. This doesn’t mean you should duplicate every piece of information in every document. However, rather than letting fear of duplicate data drive your design decisions, consider modeling your data based on what information belongs to what document.

So,

student
{ 
    _id: ObjectId(...),
    name: 'Jane',
    courses: [
    { 
        name: 'Biology 101', 
        mark: 85, 
        id:bio101 
    },
  ]
}

If its a RESTful API data, replace the course id with a GET link to the course resource

The short answer

There is none. They are exactly the same.

The long answer

Both .htm and .html are exactly the same and will work in the same way. The choice is down to personal preference, provided you’re consistent with your file naming you won’t have a problem with either.

Depending on the configuration of the web server, one of the file types will take precedence over the other. This should not be an issue since it’s unlikely that you’ll have both index.htm and index.html sitting in the same folder.

We always use the shorter .htm for our file names since file extensions are typically 3 characters long.

AND MORE ON: http://www.sightspecific.com/~mosh/WWW_FAQ/ext.html or http://www.sightspecific.com/~mosh/WWW_FAQ/ext.htm

I think I should add this part here:
There is one single slight difference between .htm and .html files. Consider a path in your server like: mydomain.com/myfolder. If you create an index.htm file inside that folder and you open that like this:mydomain.com/myfolder/, it will goes crazy and spit out your files as it is in your server,
but if you create an index.html file in there and open that directory in your browser, it will load that file. I tested this on my VPS and found this Maybe you could somehow set your server to load index.htm files by default, but I guess the .html file is the default file type for browsers to open in each directory.

Here's an example program that will send myfile.mp3 by streaming it from disk (that is, it doesn't read the whole file into memory before sending the file). The server listens on port 2000.

[Update] As mentioned by @Aftershock in the comments, util.pump is gone and was replaced with a method on the Stream prototype called pipe; the code below reflects this.

var http = require('http'),
    fileSystem = require('fs'),
    path = require('path');

http.createServer(function(request, response) {
    var filePath = path.join(__dirname, 'myfile.mp3');
    var stat = fileSystem.statSync(filePath);

    response.writeHead(200, {
        'Content-Type': 'audio/mpeg',
        'Content-Length': stat.size
    });

    var readStream = fileSystem.createReadStream(filePath);
    // We replaced all the event handlers with a simple call to readStream.pipe()
    readStream.pipe(response);
})
.listen(2000);

With Apache Commons Daemon you can now have a custom executable name and icon! You can also get a custom Windows tray monitor with your own name and icon!

I now have my service running with my own name and icon (prunsrv.exe), and the system tray monitor (prunmgr.exe) also has my own custom name and icon!

1. Download the Apache Commons Daemon binaries (you will need prunsrv.exe and prunmgr.exe).

2. Rename them to be MyServiceName.exe and MyServiceNamew.exe respectively.

3. Download WinRun4J and use the RCEDIT.exe program that comes with it to modify the Apache executable to embed your own custom icon like this:

   > RCEDIT.exe /I MyServiceName.exe customIcon.ico
   > RCEDIT.exe /I MyServiceNamew.exe customTrayIcon.ico
   

4. Now install your Windows service like this (see documentation for more details and options):

   > MyServiceName.exe //IS//MyServiceName \
     --Install="C:\path-to\MyServiceName.exe" \
     --Jvm=auto --Startup=auto --StartMode=jvm \
     --Classpath="C:\path-to\MyJarWithClassWithMainMethod.jar" \
     --StartClass=com.mydomain.MyClassWithMainMethod
   

5. Now you have a Windows service of your Jar that will run with your own icon and name! You can also launch the monitor file and it will run in the system tray with your own icon and name.

   > MyServiceNamew.exe //MS//MyServiceName

You can just plug the characters (copied from the web) into this site for a lookup.

you can use this function . Its taken from https://convertintowordpress.com/simple-jquery-table-pagination-code/

    }
    if(total_num_row % req_num_row >=1){
        num_pages=total_num_row / req_num_row;
        num_pages++;
        num_pages=Math.floor(num_pages++);
    }
    for(var i=1; i<=num_pages; i++){
        jQuery('#pagination').append("<a href='#' class='btn'>"+i+"</a>");
    }
    $tr.each(function(i){
        jQuery(this).hide();
        if(i+1 <= req_num_row){
            $tr.eq(i).show();
        }

    });
    jQuery('#pagination a').click(function(e){
        e.preventDefault();
        $tr.hide();
        var page=jQuery(this).text();
        var temp=page-1;
        var start=temp*req_num_row;
        //alert(start);

        for(var i=0; i< req_num_row; i++){

            $tr.eq(start+i).show();

        }
    });
}

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

I have found a pretty big difference in timing when testing in my browser.

I used the following script:

WARNING: running this will freeze your browser a bit, might even crash it.

var n = 10000000, i;_x000D_
i = n;_x000D_
console.time('selector');_x000D_
while (i --> 0){_x000D_
    $("body");_x000D_
}_x000D_
_x000D_
console.timeEnd('selector');_x000D_
_x000D_
i = n;_x000D_
console.time('element');_x000D_
while (i --> 0){_x000D_
    $(document.body);_x000D_
}_x000D_
_x000D_
console.timeEnd('element');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

I did 10 million interactions, and those were the results (Chrome 65):

selector: 19591.97509765625ms
element: 4947.8759765625ms

Passing the element directly is around 4 times faster than passing the selector.

This prints out all ASCII values:

int main()
{
    int i;
    i=0;
    do
    {
        printf("%d %c \n",i,i);
        i++;
    }
    while(i<=255);
    return 0;
}

and this prints out the ASCII value for a given character:

int main()
{
    int e;
    char ch;
    clrscr();
    printf("\n Enter a character : ");
    scanf("%c",&ch);
    e=ch;
    printf("\n The ASCII value of the character is : %d",e);
    getch();
    return 0;
}

I'd simply say that it was hyphenated.

Does not work, you have to do this:

if ( $("#your_select_id option[value='enter_value_here']").length == 0 ){
  alert("option doesn't exist!");
}

You simply have to pipe an iconv command before the sed command. Ex with file.txt input :

iconv -f ISO-8859-1 -t UTF8-MAC file.txt | sed 's/something/àéèêçùû/g' | .....

-f option is the 'from' codeset and -t option is the 'to' codeset conversion.

Take care of case, web pages usually show lowercase like that < charset=iso-8859-1"/> and iconv uses uppercase. You have list of iconv supported codesets in you system with command iconv -l

UTF8-MAC is modern OS Mac codeset for conversion.

there's two ways to return/back to the previous ViewController :

1. First case : if you used : self.navigationController?.pushViewController(yourViewController, animated: true) in this case you need to use self.navigationController?.popViewController(animated: true)
2. Second case : if you used : self.present(yourViewController, animated: true, completion: nil) in this case you need to use self.dismiss(animated: true, completion: nil)

In the first case , be sure that you embedded your ViewController to a navigationController in your storyboard

Below should work.

SimpleDateFormat df = new SimpleDateFormat("dd-MMM-yyyy");
Date oldDate = df.parse(df.format(date)); //this date is your old date object

The cex parameter will do that for you.

barplot(a, beside = T,
        col = 1:6, space = c(0, 2))

You're trying to use a dict as a key to another dict or in a set. That does not work because the keys have to be hashable. As a general rule, only immutable objects (strings, integers, floats, frozensets, tuples of immutables) are hashable (though exceptions are possible). So this does not work:

>>> dict_key = {"a": "b"}
>>> some_dict[dict_key] = True
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'dict'

To use a dict as a key you need to turn it into something that may be hashed first. If the dict you wish to use as key consists of only immutable values, you can create a hashable representation of it like this:

>>> key = frozenset(dict_key.items())

Now you may use key as a key in a dict or set:

>>> some_dict[key] = True
>>> some_dict
{frozenset([('a', 'b')]): True}

Of course you need to repeat the exercise whenever you want to look up something using a dict:

>>> some_dict[dict_key]                     # Doesn't work
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'dict'
>>> some_dict[frozenset(dict_key.items())]  # Works
True

If the dict you wish to use as key has values that are themselves dicts and/or lists, you need to recursively "freeze" the prospective key. Here's a starting point:

def freeze(d):
    if isinstance(d, dict):
        return frozenset((key, freeze(value)) for key, value in d.items())
    elif isinstance(d, list):
        return tuple(freeze(value) for value in d)
    return d

Solve that by using std::basic_string<TCHAR> instead of std::string and it should work fine regardless of your character setting.

The answer above did not work for me (python 3.6, Anaconda, pandas 0.20.3). It worked with

conda install -c anaconda pandas 

Unfortunately I do not know how to help with Eclipse.

use the --expression option

grep searchterm myfile.csv | sed --expression='s/replaceme/withthis/g'

Use break:

while (true) {
    ....
    if (obj == null) {
        break;
    }
    ....
}

However, if your code looks exactly like you have specified you can use a normal while loop and change the condition to obj != null:

while (obj != null) {
    ....
}

CSS?

td {
  padding-top: 2px;
  padding-bottom: 2px;
}

The connection string should be set like this:

jdbc:mysql://localhost/db?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC

If you are defining the connection in an xml file (such as persistence.xml, standalone-full.xml, etc..), instead of & you should use & or use a CDATA block.

here is a link to generate a short list of options available to npm; it filters on the keywords unused packages

https://www.npmjs.com/search?q=unused%20packages

Use a List<String>, such as an ArrayList<String>. It's dynamically growable, unlike arrays (see: Effective Java 2nd Edition, Item 25: Prefer lists to arrays).

import java.util.*;
//....

List<String> list = new ArrayList<String>();
list.add("1");
list.add("2");
list.add("3");
System.out.println(list); // prints "[1, 2, 3]"

If you insist on using arrays, you can use java.util.Arrays.copyOf to allocate a bigger array to accomodate the additional element. This is really not the best solution, though.

static <T> T[] append(T[] arr, T element) {
    final int N = arr.length;
    arr = Arrays.copyOf(arr, N + 1);
    arr[N] = element;
    return arr;
}

String[] arr = { "1", "2", "3" };
System.out.println(Arrays.toString(arr)); // prints "[1, 2, 3]"
arr = append(arr, "4");
System.out.println(Arrays.toString(arr)); // prints "[1, 2, 3, 4]"

This is O(N) per append. ArrayList, on the other hand, has O(1) amortized cost per operation.

I you have more than one group of radio buttons on the same page you can also try this to get the value of radio button:

$("input:radio[type=radio]").click(function() {
    var value = $(this).val();
    alert(value);
});

Another good use for function pointers:
Switching between versions painlessly

They're very handy to use for when you want different functions at different times, or different phases of development. For instance, I'm developing an application on a host computer that has a console, but the final release of the software will be put on an Avnet ZedBoard (which has ports for displays and consoles, but they are not needed/wanted for the final release). So during development, I will use printf to view status and error messages, but when I'm done, I don't want anything printed. Here's what I've done:

version.h

// First, undefine all macros associated with version.h
#undef DEBUG_VERSION
#undef RELEASE_VERSION
#undef INVALID_VERSION


// Define which version we want to use
#define DEBUG_VERSION       // The current version
// #define RELEASE_VERSION  // To be uncommented when finished debugging

#ifndef __VERSION_H_      /* prevent circular inclusions */
    #define __VERSION_H_  /* by using protection macros */
    void board_init();
    void noprintf(const char *c, ...); // mimic the printf prototype
#endif

// Mimics the printf function prototype. This is what I'll actually 
// use to print stuff to the screen
void (* zprintf)(const char*, ...); 

// If debug version, use printf
#ifdef DEBUG_VERSION
    #include <stdio.h>
#endif

// If both debug and release version, error
#ifdef DEBUG_VERSION
#ifdef RELEASE_VERSION
    #define INVALID_VERSION
#endif
#endif

// If neither debug or release version, error
#ifndef DEBUG_VERSION
#ifndef RELEASE_VERSION
    #define INVALID_VERSION
#endif
#endif

#ifdef INVALID_VERSION
    // Won't allow compilation without a valid version define
    #error "Invalid version definition"
#endif

In version.c I will define the 2 function prototypes present in version.h

version.c

#include "version.h"

/*****************************************************************************/
/**
* @name board_init
*
* Sets up the application based on the version type defined in version.h.
* Includes allowing or prohibiting printing to STDOUT.
*
* MUST BE CALLED FIRST THING IN MAIN
*
* @return    None
*
*****************************************************************************/
void board_init()
{
    // Assign the print function to the correct function pointer
    #ifdef DEBUG_VERSION
        zprintf = &printf;
    #else
        // Defined below this function
        zprintf = &noprintf;
    #endif
}

/*****************************************************************************/
/**
* @name noprintf
*
* simply returns with no actions performed
*
* @return   None
*
*****************************************************************************/
void noprintf(const char* c, ...)
{
    return;
}

Notice how the function pointer is prototyped in version.h as

void (* zprintf)(const char *, ...);

When it is referenced in the application, it will start executing wherever it is pointing, which has yet to be defined.

In version.c, notice in the board_init()function where zprintf is assigned a unique function (whose function signature matches) depending on the version that is defined in version.h

zprintf = &printf; zprintf calls printf for debugging purposes

or

zprintf = &noprint; zprintf just returns and will not run unnecessary code

Running the code will look like this:

mainProg.c

#include "version.h"
#include <stdlib.h>
int main()
{
    // Must run board_init(), which assigns the function
    // pointer to an actual function
    board_init();

    void *ptr = malloc(100); // Allocate 100 bytes of memory
    // malloc returns NULL if unable to allocate the memory.

    if (ptr == NULL)
    {
        zprintf("Unable to allocate memory\n");
        return 1;
    }

    // Other things to do...
    return 0;
}

The above code will use printf if in debug mode, or do nothing if in release mode. This is much easier than going through the entire project and commenting out or deleting code. All that I need to do is change the version in version.h and the code will do the rest!

Hadoop file system does not support appending data to the existing files. Although, you can load your CSV file into HDFS and tell Hive to treat it as an external table.

The amount of memory allocated for the Java process is pretty much on-par with what I would expect. I've had similar problems running Java on embedded/memory limited systems. Running any application with arbitrary VM limits or on systems that don't have adequate amounts of swap tend to break. It seems to be the nature of many modern apps that aren't design for use on resource-limited systems.

You have a few more options you can try and limit your JVM's memory footprint. This might reduce the virtual memory footprint:

-XX:ReservedCodeCacheSize=32m Reserved code cache size (in bytes) - maximum code cache size. [Solaris 64-bit, amd64, and -server x86: 48m; in 1.5.0_06 and earlier, Solaris 64-bit and and64: 1024m.]

-XX:MaxPermSize=64m Size of the Permanent Generation. [5.0 and newer: 64 bit VMs are scaled 30% larger; 1.4 amd64: 96m; 1.3.1 -client: 32m.]

Also, you also should set your -Xmx (max heap size) to a value as close as possible to the actual peak memory usage of your application. I believe the default behavior of the JVM is still to double the heap size each time it expands it up to the max. If you start with 32M heap and your app peaked to 65M, then the heap would end up growing 32M -> 64M -> 128M.

You might also try this to make the VM less aggressive about growing the heap:

-XX:MinHeapFreeRatio=40 Minimum percentage of heap free after GC to avoid expansion.

Also, from what I recall from experimenting with this a few years ago, the number of native libraries loaded had a huge impact on the minimum footprint. Loading java.net.Socket added more than 15M if I recall correctly (and I probably don't).

7-zip understands most kinds of archives, including rpm and the included cpio.

<customErrors defaultRedirect="~/404.aspx" mode="On">
    <error statusCode="404" redirect="~/404.aspx"/>
</customErrors>

Code above is only for "Page Not Found Error-404" if file extension is known(.html,.aspx etc)

Beside it you also have set Customer Errors for extension not known or not correct as

.aspwx or .vivaldo. You have to add httperrors settings in web.config

<httpErrors  errorMode="Custom"> 
       <error statusCode="404" prefixLanguageFilePath="" path="/404.aspx"         responseMode="Redirect" />
</httpErrors>
<modules runAllManagedModulesForAllRequests="true"/>

it must be inside the <system.webServer> </system.webServer>

There are two project types in VS for ASP.NET projects:

Web Application Projects (which notably have a .csproj or .vbproj file to store these settings) have a Properties node under the project. On the Web tab, you can configure the Project URL (assuming IIS Express or IIS) to use whatever port you want, and just click the Create Virtual Directory button. These settings are saved to the project file:

<ProjectExtensions>
  <VisualStudio>
    <FlavorProperties GUID="{349c5851-65df-11da-9384-00065b846f21}">
      <WebProjectProperties>
       <DevelopmentServerPort>10531</DevelopmentServerPort>
       ...
     </WebProjectProperties>
    </FlavorProperties>
  </VisualStudio>
</ProjectExtensions>

Web Site Projects are different. They don't have a .*proj file to store settings in; instead, the settings are set in the solution file. In VS2013, the settings look something like this:

Project("{E24C65DC-7377-472B-9ABA-BC803B73C61A}") = "WebSite1(1)", "http://localhost:10528", "{401397AC-86F6-4661-A71B-67B4F8A3A92F}"
    ProjectSection(WebsiteProperties) = preProject
        UseIISExpress = "true"
        TargetFrameworkMoniker = ".NETFramework,Version%3Dv4.5"
        ...
        SlnRelativePath = "..\..\WebSites\WebSite1\"
        DefaultWebSiteLanguage = "Visual Basic"
    EndProjectSection
EndProject

Because the project is identified by the URL (including port), there isn't a way in the VS UI to change this. You should be able to modify the solution file though, and it should work.

You can use the Web API FontFace constructor (also Typescript) without need of CSS:

export async function loadFont(fontFamily: string, url: string): Promise<void> {
    const font = new FontFace(fontFamily, `local(${fontFamily}), url(${url})`);
    // wait for font to be loaded
    await font.load();
    // add font to document
    document.fonts.add(font);
    // enable font with CSS class
    document.body.classList.add("fonts-loaded");
}

import ComicSans from "./assets/fonts/ComicSans.ttf";

loadFont("Comic Sans ", ComicSans).catch((e) => {
    console.log(e);
});

Declare a file font.ts with your modules (TS only):

declare module "*.ttf";
declare module "*.woff";
declare module "*.woff2";

If TS cannot find FontFace type as its still officially WIP, add this declaration to your project. It will work in your browser, except for IE.

Depending on how it's being used, it might be necessary and even handy. http://php.net/manual/en/language.operators.logical.php

// "||" has a greater precedence than "or"

// The result of the expression (false || true) is assigned to $e
// Acts like: ($e = (false || true))
$e = false || true;

// The constant false is assigned to $f and then true is ignored
// Acts like: (($f = false) or true)
$f = false or true;

But in most cases it seems like more of a developer taste thing, like every occurrence of this that I've seen in CodeIgniter framework like @Sarfraz has mentioned.

For example here is a element like button for adding item to basket and appropriate attributes for saving in localStorage.

'<a href="#" cartBtn pr_id='+e.id+' pr_name_en="'+e.nameEn+'" pr_price="'+e.price+'" pr_image="'+e.image+'" class="btn btn-primary"><i class="fa fa-shopping-cart"></i>Add to cart</a>'

var productArray=[];


$(document).on('click','[cartBtn]',function(e){
  e.preventDefault();
  $(this).html('<i class="fa fa-check"></i>Added to cart');
  console.log('Item added ');
  var productJSON={"id":$(this).attr('pr_id'), "nameEn":$(this).attr('pr_name_en'), "price":$(this).attr('pr_price'), "image":$(this).attr('pr_image')};


  if(localStorage.getObj('product')!==null){
    productArray=localStorage.getObj('product');
    productArray.push(productJSON);  
    localStorage.setObj('product', productArray);  
  }
  else{
    productArray.push(productJSON);  
    localStorage.setObj('product', productArray);  
  }


});

Storage.prototype.setObj = function(key, value) {
    this.setItem(key, JSON.stringify(value));
}

Storage.prototype.getObj = function(key) {
    var value = this.getItem(key);
    return value && JSON.parse(value);
}

After adding JSON object to Array result is (in LocalStorage):

[{"id":"99","nameEn":"Product Name1","price":"767","image":"1462012597217.jpeg"},{"id":"93","nameEn":"Product Name2","price":"76","image":"1461449637106.jpeg"},{"id":"94","nameEn":"Product Name3","price":"87","image":"1461449679506.jpeg"}]

after this action you can easily send data to server as List in Java

Full code example is here

How do I store a simple cart using localStorage?

Why would you want to do this?

IMHO you should store the date as default type and if needed fetch it transforming to desired format.

You could get away with specifying column's format but with a view. I don't know other methods.

Edited:

Seriously, in my opinion, you should create a view on that a table with date type. I'm talking about something like this:

create table sample_table ( id serial primary key, timestamp date); 

and than

create view v_example_table as select id, to_char(date, 'yyyymmmm');

And use v_example_table in your application.

If you really need to do this, use reverse proxy.

For example, with nginx as reverse proxy

server {
  listen       api.mydomain.com:80;
  server_name  api.mydomain.com;
  location / {
    proxy_pass http://127.0.0.1:8000;
  }
}

import requests

site_request = requests.get("https://abhiunix.in")

site_response = str(site_request.content)

print(site_response)

You can do it either way.

Most of it is explained in the GC Tuning Guide (which you would do well to read anyway).

The command line option -verbose:gc causes information about the heap and garbage collection to be printed at each collection. For example, here is output from a large server application:

[GC 325407K->83000K(776768K), 0.2300771 secs]
[GC 325816K->83372K(776768K), 0.2454258 secs]
[Full GC 267628K->83769K(776768K), 1.8479984 secs]

Here we see two minor collections followed by one major collection. The numbers before and after the arrow (e.g., 325407K->83000K from the first line) indicate the combined size of live objects before and after garbage collection, respectively. After minor collections the size includes some objects that are garbage (no longer alive) but that cannot be reclaimed. These objects are either contained in the tenured generation, or referenced from the tenured or permanent generations.

The next number in parentheses (e.g., (776768K) again from the first line) is the committed size of the heap: the amount of space usable for java objects without requesting more memory from the operating system. Note that this number does not include one of the survivor spaces, since only one can be used at any given time, and also does not include the permanent generation, which holds metadata used by the virtual machine.

The last item on the line (e.g., 0.2300771 secs) indicates the time taken to perform the collection; in this case approximately a quarter of a second.

The format for the major collection in the third line is similar.

The format of the output produced by -verbose:gc is subject to change in future releases.

I'm not certain why there's a PSYoungGen in yours; did you change the garbage collector?

It's not magic.

The behavior of this code in C is described in section 6.7.8.21 of the C specification (online draft of C spec): for the elements that don't have a specified value, the compiler initializes pointers to NULL and arithmetic types to zero (and recursively applies this to aggregates).

The behavior of this code in C++ is described in section 8.5.1.7 of the C++ specification (online draft of C++ spec): the compiler aggregate-initializes the elements that don't have a specified value.

Also, note that in C++ (but not C), you can use an empty initializer list, causing the compiler to aggregate-initialize all of the elements of the array:

char array[100] = {};

As for what sort of code the compiler might generate when you do this, take a look at this question: Strange assembly from array 0-initialization

Thanks a lot it worked , please note I did a typo in php as it should be mysqli_query( $con2, $sql )

Just use str - for example:

Rxjs v 6.*

It got simplified with newer version of rxjs .

1) Operators

import {map} from 'rxjs/operators';

2) Others

import {Observable,of, from } from 'rxjs';

Instead of chaining we need to pipe . For example

Old syntax :

source.map().switchMap().subscribe()

New Syntax:

source.pipe(map(), switchMap()).subscribe()

Note: Some operators have a name change due to name collisions with JavaScript reserved words! These include:

do -> tap,

catch -> catchError

switch -> switchAll

finally -> finalize

Rxjs v 5.*

I am writing this answer partly to help myself as I keep checking docs everytime I need to import an operator . Let me know if something can be done better way.

1) import { Rx } from 'rxjs/Rx';

This imports the entire library. Then you don't need to worry about loading each operator . But you need to append Rx. I hope tree-shaking will optimize and pick only needed funcionts( need to verify ) As mentioned in comments , tree-shaking can not help. So this is not optimized way.

public cache = new Rx.BehaviorSubject('');

Or you can import individual operators .

This will Optimize your app to use only those files :

2) import { _______ } from 'rxjs/_________';

This syntax usually used for main Object like Rx itself or Observable etc.,

Keywords which can be imported with this syntax

 Observable, Observer, BehaviorSubject, Subject, ReplaySubject

3) import 'rxjs/add/observable/__________';

Update for Angular 5

With Angular 5, which uses rxjs 5.5.2+

import { empty } from 'rxjs/observable/empty';
import { concat} from 'rxjs/observable/concat';

These are usually accompanied with Observable directly. For example

Observable.from()
Observable.of()

Other such keywords which can be imported using this syntax:

concat, defer, empty, forkJoin, from, fromPromise, if, interval, merge, of, 
range, throw, timer, using, zip

4) import 'rxjs/add/operator/_________';

Update for Angular 5

With Angular 5, which uses rxjs 5.5.2+

import { filter } from 'rxjs/operators/filter';
import { map } from 'rxjs/operators/map';

These usually come in the stream after the Observable is created. Like flatMap in this code snippet:

Observable.of([1,2,3,4])
          .flatMap(arr => Observable.from(arr));

Other such keywords using this syntax:

audit, buffer, catch, combineAll, combineLatest, concat, count, debounce, delay, 
distinct, do, every, expand, filter, finally, find , first, groupBy,
ignoreElements, isEmpty, last, let, map, max, merge, mergeMap, min, pluck, 
publish, race, reduce, repeat, scan, skip, startWith, switch, switchMap, take, 
takeUntil, throttle, timeout, toArray, toPromise, withLatestFrom, zip

FlatMap: flatMap is alias to mergeMap so we need to import mergeMap to use flatMap.

Note for /add imports :

We only need to import once in whole project. So its advised to do it at a single place. If they are included in multiple files, and one of them is deleted, the build will fail for wrong reasons.

osascript -e 'tell app "Terminal"
   do script "echo hello"
end tell'

This opens a new terminal and executes the command "echo hello" inside it.

As of MySql 5.1 version reference

BIT(M) =  approximately (M+7)/8 bytes, 
BIT(1) =  (1+7)/8 = 1 bytes (8 bits)

=========================================================================

TINYINT(1) take 8 bits.

For those looking for an efficient method to convert an image file to a Base64 string without compression or converting the file to a bitmap first, you can instead encode the file as base64

val base64EncodedImage = FileInputStream(imageItem.localSrc).use {inputStream - >
    ByteArrayOutputStream().use {outputStream - >
            Base64OutputStream(outputStream, Base64.DEFAULT).use {
                base64FilterStream - >
                    inputStream.copyTo(base64FilterStream)
                base64FilterStream.flush()
                outputStream.toString()
            }
      }
}

Hope this helps!

I got this error because I was doing File.Move to a file path without a file name, need to specify the full path in the destination.

I have found it satisfactory to use ls and cd within ipython notebook to find the file. Then type cat your_file_name into the cell, and you'll get back the contents of the file, which you can then paste into the cell as code.

You can use following code

  DirectoryInfo di = Directory.CreateDirectory(path);

0..($letters.count-1) | foreach { "Value: {0}, Index: {1}" -f $letters[$_],$_}

AD Powershell module should be listed under installed Features. See image:

May be useful:

The code that calls the Trigger should go after the event is called.

For example, I have some code that I want to be executed when #expense_tickets value is changed, and also, when page is reload

$(function() { 

  $("#expense_tickets").change(function() {
    // code that I want to be executed when #expense_tickets value is changed, and also, when page is reload
  });

  // now we trigger the change event
  $("#expense_tickets").trigger("change");

})

add \ before special characters:

s/\?page=one&/page\/one\//g

etc.

If you already have var parent = document.querySelector('.parent'); you can do this to scope the search to parent's children:

parent.querySelector('.child')

This code works for me:

<?php
$date = "21.12.2015";
$newDate = date("d.m.Y",strtotime($date."+2 day"));
echo $newDate; // print 23.12.2015
?>

Disclaimer: I am from 42matters, who provides this data already on https://42matters.com/api , feel free to check it out or drop us a line.

As lenik mentioned there are open-source libraries that already help with obtaining some data from GPlay. If you want to build one yourself you can try to parse the Google Play App page, but you should pay attention to the following:

• Make sure the URL you are trying to parse is not blocked in robots.txt - e.g. https://play.google.com/robots.txt
• Make sure that you are not doing it too often, Google will throttle and potentially blacklist you if you are doing it too much.
• Send a correct User-Agent header to actually show you are a bot
• The page of an app is big - make sure you accept gzip and request the mobile version
• GPlay website is not an API, it doesn't care that you parse it so it will change over time. Make sure you handle changes - e.g. by having test to make sure you get what you expected.

So that in mind getting one page metadata is a matter of fetching the page html and parsing it properly. With JSoup you can try:

      HttpClient httpClient = HttpClientBuilder.create().build();
      HttpGet request = new HttpGet(crawlUrl);
      HttpResponse rsp = httpClient.execute(request);

      int statusCode = rsp.getStatusLine().getStatusCode();

      if (statusCode == 200) {
           String content = EntityUtils.toString(rsp.getEntity());    
           Document doc = Jsoup.parse(content);
           //parse content, whatever you need
           Element price = doc.select("[itemprop=price]").first();
      }      

For that very simple use case that should get you started. However, the moment you want to do more interesting stuff, things get complicated:

• Search is forbidden in robots.
• Keeping app metadata up-to-date is hard to do. There are more than 2.2m apps, if you want to refresh their metadata daily there are 2.2 requests/day, which will 1) get blocked immediately, 2) costs a lot of money - pessimistic 220gb data transfer per day if one app is 100k
• How do you discover new apps
• How do you get pricing in each country, translations of each language

The list goes on. If you don't want to do all this by yourself, you can consider 42matters API, which supports lookup and search, top google charts, advanced queries and filters. And this for 35 languages and more than 50 countries.

The compilation of a C++ program involves three steps:

1. Preprocessing: the preprocessor takes a C++ source code file and deals with the #includes, #defines and other preprocessor directives. The output of this step is a "pure" C++ file without pre-processor directives.

2. Compilation: the compiler takes the pre-processor's output and produces an object file from it.

3. Linking: the linker takes the object files produced by the compiler and produces either a library or an executable file.

Preprocessing

The preprocessor handles the preprocessor directives, like #include and #define. It is agnostic of the syntax of C++, which is why it must be used with care.

It works on one C++ source file at a time by replacing #include directives with the content of the respective files (which is usually just declarations), doing replacement of macros (#define), and selecting different portions of text depending of #if, #ifdef and #ifndef directives.

The preprocessor works on a stream of preprocessing tokens. Macro substitution is defined as replacing tokens with other tokens (the operator ## enables merging two tokens when it makes sense).

After all this, the preprocessor produces a single output that is a stream of tokens resulting from the transformations described above. It also adds some special markers that tell the compiler where each line came from so that it can use those to produce sensible error messages.

Some errors can be produced at this stage with clever use of the #if and #error directives.

Compilation

The compilation step is performed on each output of the preprocessor. The compiler parses the pure C++ source code (now without any preprocessor directives) and converts it into assembly code. Then invokes underlying back-end(assembler in toolchain) that assembles that code into machine code producing actual binary file in some format(ELF, COFF, a.out, ...). This object file contains the compiled code (in binary form) of the symbols defined in the input. Symbols in object files are referred to by name.

Object files can refer to symbols that are not defined. This is the case when you use a declaration, and don't provide a definition for it. The compiler doesn't mind this, and will happily produce the object file as long as the source code is well-formed.

Compilers usually let you stop compilation at this point. This is very useful because with it you can compile each source code file separately. The advantage this provides is that you don't need to recompile everything if you only change a single file.

The produced object files can be put in special archives called static libraries, for easier reusing later on.

It's at this stage that "regular" compiler errors, like syntax errors or failed overload resolution errors, are reported.

Linking

The linker is what produces the final compilation output from the object files the compiler produced. This output can be either a shared (or dynamic) library (and while the name is similar, they haven't got much in common with static libraries mentioned earlier) or an executable.

It links all the object files by replacing the references to undefined symbols with the correct addresses. Each of these symbols can be defined in other object files or in libraries. If they are defined in libraries other than the standard library, you need to tell the linker about them.

At this stage the most common errors are missing definitions or duplicate definitions. The former means that either the definitions don't exist (i.e. they are not written), or that the object files or libraries where they reside were not given to the linker. The latter is obvious: the same symbol was defined in two different object files or libraries.

The answers here were helpful, however I need more than that: not only month, date, month, hours & seconds, for a default name.

Interestingly, though prepend of "0" was needed for all above, " + 1" was needed only for month, not others.

As example:

("0" + (d.getMonth() + 1)).slice(-2)     // Note: +1 is needed
("0" + (d.getHours())).slice(-2)         // Note: +1 is not needed

for search all rows in lowercase

EDIT:

So which am I supposed to use? The proper 4 letter extension suggested by the creator, or the 3 letter extension found in the wild west of the internet?

This question could be:

1. A request for advice; or

2. A natural expression of that particular emotion which is experienced, while one is observing that some official recommendation is being disregarded—prominently, or even predominantly.

People differ in their predilection for following:

1. Official advice; or

2. The preponderance of practice.

Of course, I am unlikely to influence you, regarding which of these two paths you prefer to take!

In what follows (and, in the spirit of science), I merely make an hypothesis, about what (merely as a matter of fact) led the majority of people to use the 3-letter extension. And, I focus on efficient causes.

By this, I do not intend moral exhortation. As you may recall, the fact that something is, does not imply that it should be.

Whatever your personal inclination, be it to follow one path or the other, I do not object.

(End of edit.)

The suggestion, that this preference (in real life usage) was caused by a 8.3 character DOS-ish limitation, IMO is a red herring (erroneous and misleading).

As of August, 2016, the Google search counts for YML and YAML were approximately 6,000,000 and 4,100,000 (to two digits of precision). Furthermore, the "YAML" count was unfairly high because it included mention of the language by name, beyond its use as an extension.

As of July, 2018, the Google's search counts for YML and YAML were approximately 8,100,000 and 4,100,000 (again, to two digits of precision). So, in the last two years, YML has essentially doubled in popularity, but YAML has stayed the same.

Another cultural measure is websites which attempt to explain file extensions. For example, on the FilExt website (as of July, 2018), the page for YAML results in: "Ooops! The FILEXT.com database does not have any information on file extension .YAML."

Whereas, it has an entry for YML, which gives: "YAML...uses a text file and organizes it into a format which is Human-readable. 'database.yml' is a typical example when YAML is used by Ruby on Rails to connect to a database."

As of November, 2014, Wikipedia's article on extension YML still stated that ".yml" is "the file extension for the YAML file format" (emphasis added). Its YAML article lists both extensions, without expressing a preference.

The extension ".yml" is sufficiently clear, is more brief (thus easier to type and recognize), and is much more common.

Of course, both of these extensions could be viewed as abbreviations of a long, possible extension, ".yamlaintmarkuplanguage". But programmers (and users) don't want to type all of that!

Instead, we programmers (and users) want to type as little as possible, and still yet be unambiguous and clear. And we want to see what kind of file it is, as quickly as possible, without reading a longer word. Typing just how many characters accomplishes both of these goals? Isn't the answer three (3)? In other words, YML?

Wikipedia's Category:Filename_extensions page lists entries for .a, .o and .Z. Somehow, it missed .c and .h (used by the C language). These example single-letter extensions help us to see that extensions should be as long as necessary, but no longer (to half-quote Albert Einstein).

Instead, notice that, in general, few extensions start with "Y". Commonly, on the other hand, the letter X is used for a great variety of meanings including "cross," "extensible," "extreme," "variable," etc. (e.g. in XML). So starting with "Y" already conveys much information (in terms of information theory), whereas starting with "X" does not.

Linguistically speaking, therefore, the acronym "XML" has (in a way) only two informative letters ("M" and "L"). "YML", instead, has three informative letters ("M", "L" and "Y"). Indeed, the existing set of acronyms beginning with Y seems extremely small. By implication, this is why a four letter YAML file extension feels greatly overspecified.

Perhaps this is why we see in practice that the "linguistic" pressure (in natural use) to lengthen the abbreviation in question to four (4) characters is weak, and the "linguistic" pressure to shorten this abbreviation to three (3) characters is strong.

Purely as a result, probably, of these factors (and not as an official endorsement), I would note that the YAML.org website's latest news item (from November, 2011) is all about a project written in JavaScript, JS-YAML, which, itself, internally prefers to use the extension ".yml".

The above-mentioned factors may have been the main ones; nevertheless, all the factors (known or unknown) have resulted in the abbreviated, three (3) character extension becoming the one in predominant use for YAML—despite the inventors' preference.

".YML" seems to be the de facto standard. Yet the same inventors were perceptive and correct, about the world's need for a human-readable data language. And we should thank them for providing it.

I need a list of files that had changed content between two commits (only added or modified), so I used:

git diff --name-only --diff-filter=AM <commit hash #1> <commit hash #2>

The different diff-filter options from the git diff documentation:

diff-filter=[(A|C|D|M|R|T|U|X|B)…?[*]]

Select only files that are Added (A), Copied (C), Deleted (D), Modified (M), Renamed (R), have their type (i.e. regular file, symlink, submodule, …?) changed (T), are Unmerged (U), are Unknown (X), or have had their pairing Broken (B). Any combination of the filter characters (including none) can be used. When * (All-or-none) is added to the combination, all paths are selected if there is any file that matches other criteria in the comparison; if there is no file that matches other criteria, nothing is selected.

Also, these upper-case letters can be downcased to exclude. E.g. --diff-filter=ad excludes added and deleted paths.

If you want to list the status as well (e.g. A / M), change --name-only to --name-status.

According to PostgreSQL documentation (4.1.2.1. String Constants):

 To include a single-quote character within a string constant, write two 
 adjacent single quotes, e.g. 'Dianne''s horse'.

See also the standard_conforming_strings parameter, which controls whether escaping with backslashes works.

• If you use a service you will get the instance of a function ("this" keyword).
• If you use a factory you will get the value that is returned by invoking the function reference (the return statement in factory)

Factory and Service are the most commonly used recipes. The only difference between them is that Service recipe works better for objects of custom type, while Factory can produce JavaScript primitives and functions.

Good News

As of today 11th April 2020, this is easily possible with backdrop-filter CSS property which is now a stable feature in Chrome, Safari & Edge.

I wanted this in our Hybrid mobile app so also available in Android/Chrome Webview & Safari WebView.

1. https://developer.mozilla.org/en-US/docs/Web/CSS/backdrop-filter
2. https://caniuse.com/#search=backdrop-filter

Code Example:

Simply add the CSS property:

.my-class {
    backdrop-filter: blur(30px);
    background: transparent;     // Make sure there is not backgorund
}

UI Example 2

Let's take an example of McDonald's app because it's quite colourful. I took its screenshot and added as the background in the body of my app.

I wanted to show a text on top of it with the glossy effect. Using backdrop-filter: blur(20px); on the overlay above it, I was able to see this:

I had got the same CORS error while working on a Vue.js project. You can resolve this either by building a proxy server or another way would be to disable the security settings of your browser (eg, CHROME) for accessing cross origin apis (this is temporary solution & not the best way to solve the issue). Both these solutions had worked for me. The later solution does not require any mock server or a proxy server to be build. Both these solutions can be resolved at the front end.

You can disable the chrome security settings for accessing apis out of the origin by typing the below command on the terminal:

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --user-data-dir="/tmp/chrome_dev_session" --disable-web-security

After running the above command on your terminal, a new chrome window with security settings disabled will open up. Now, run your program (npm run serve / npm run dev) again and this time you will not get any CORS error and would be able to GET request using axios.

Hope this helps!

It was throwing me this error when I using switch in a function with variables declared in my class:

private void ShowCalendar(final Activity context, Point p, int type) 
{
    switch (type) {
        case type_cat:
            break;

        case type_region:
            break;

        case type_city:
            break;

        default:
            //sth
            break;
    }
}

The problem was solved when I declared final to the variables in the start of the class:

final int type_cat=1, type_region=2, type_city=3;

SHA1 is a one way hash. So you can not really revert it.

That's why applications use it to store the hash of the password and not the password itself.

Like every hash function SHA-1 maps a large input set (the keys) to a smaller target set (the hash values). Thus collisions can occur. This means that two values of the input set map to the same hash value.

Obviously the collision probability increases when the target set is getting smaller. But vice versa this also means that the collision probability decreases when the target set is getting larger and SHA-1's target set is 160 bit.

Jeff Preshing, wrote a very good blog about Hash Collision Probabilities that can help you to decide which hash algorithm to use. Thanks Jeff.

In his blog he shows a table that tells us the probability of collisions for a given input set.

As you can see the probability of a 32-bit hash is 1 in 2 if you have 77163 input values.

A simple java program will show us what his table shows:

public class Main {

    public static void main(String[] args) {
        char[] inputValue = new char[10];

        Map<Integer, String> hashValues = new HashMap<Integer, String>();

        int collisionCount = 0;

        for (int i = 0; i < 77163; i++) {
            String asString = nextValue(inputValue);
            int hashCode = asString.hashCode();
            String collisionString = hashValues.put(hashCode, asString);
            if (collisionString != null) {
                collisionCount++;
                System.out.println("Collision: " + asString + " <-> " + collisionString);
            }
        }

        System.out.println("Collision count: " + collisionCount);
    }

    private static String nextValue(char[] inputValue) {
        nextValue(inputValue, 0);

        int endIndex = 0;
        for (int i = 0; i < inputValue.length; i++) {
            if (inputValue[i] == 0) {
                endIndex = i;
                break;
            }
        }

        return new String(inputValue, 0, endIndex);
    }

    private static void nextValue(char[] inputValue, int index) {
        boolean increaseNextIndex = inputValue[index] == 'z';

        if (inputValue[index] == 0 || increaseNextIndex) {
            inputValue[index] = 'A';
        } else {
            inputValue[index] += 1;
        }

        if (increaseNextIndex) {
            nextValue(inputValue, index + 1);
        }

    }

}

My output end with:

Collision: RvV <-> SWV
Collision: SvV <-> TWV
Collision: TvV <-> UWV
Collision: UvV <-> VWV
Collision: VvV <-> WWV
Collision: WvV <-> XWV
Collision count: 35135

It produced 35135 collsions and that's the nearly the half of 77163. And if I ran the program with 30084 input values the collision count is 13606. This is not exactly 1 in 10, but it is only a probability and the example program is not perfect, because it only uses the ascii chars between A and z.

Let's take the last reported collision and check

System.out.println("VvV".hashCode());
System.out.println("WWV".hashCode());

My output is

86390
86390

Conclusion:

If you have a SHA-1 value and you want to get the input value back you can try a brute force attack. This means that you have to generate all possible input values, hash them and compare them with the SHA-1 you have. But that will consume a lot of time and computing power. Some people created so called rainbow tables for some input sets. But these do only exist for some small input sets.

And remember that many input values map to a single target hash value. So even if you would know all mappings (which is impossible, because the input set is unbounded) you still can't say which input value it was.

The following works on all browsers for my 200 figures, for any width percentage -- despite being illegal. Jukka said 'Use it anyway.' (The class just floats the image left or right and sets margins.) I can't imagine why this isn't the standard approach!

<img class="fl" width="66%"
src="A-Images/0.5_Saltation.jpg"
alt="Schematic models of chromosomes ..." />

Change the window width and the image scales obligingly.

You may try this as regular user in CLI on Linux host:

function get_local_ipv4() {
  $out = split(PHP_EOL,shell_exec("/sbin/ifconfig"));
  $local_addrs = array();
  $ifname = 'unknown';
  foreach($out as $str) {
    $matches = array();
    if(preg_match('/^([a-z0-9]+)(:\d{1,2})?(\s)+Link/',$str,$matches)) {
      $ifname = $matches[1];
      if(strlen($matches[2])>0) {
        $ifname .= $matches[2];
      }
    } elseif(preg_match('/inet addr:((?:25[0-5]|2[0-4]\d|1\d\d|[1-9]\d|\d)(?:[.](?:25[0-5]|2[0-4]\d|1\d\d|[1-9]\d|\d)){3})\s/',$str,$matches)) {
      $local_addrs[$ifname] = $matches[1];
    }
  }
  return $local_addrs;
}

$addrs = get_local_ipv4();
var_export($addrs);

Output:

array (
  'eth0' => '192.168.1.1',
  'eth0:0' => '192.168.2.1',
  'lo' => '127.0.0.1',
  'vboxnet0' => '192.168.56.1',
)

Font.Name, Font.XYZProperty, etc are readonly as Font is an immutable object, so you need to specify a new Font object to replace it:

mainForm.lblName.Font = new Font("Arial", mainForm.lblName.Font.Size);

Check the constructor of the Font class for further options.

For anyone reading this who is using EclipseLink for JPA 2.0, here are the two annotations I had to use to get JPA to persist data, where "MySequenceGenerator" is whatever name you want to give the generator, "myschema" is the name of the schema in your database that contains the sequence object, and "mysequence" is the name of the sequence object in the database.

@GeneratedValue(strategy= GenerationType.SEQUENCE, generator="MySequenceGenerator")
@SequenceGenerator(allocationSize=1, schema="myschema",  name="MySequenceGenerator", sequenceName = "mysequence")

For those using EclipseLink (and possibly other JPA providers), it is CRITICAL that you set the allocationSize attribute to match the INCREMENT value defined for your sequence in the database. If you don't, you'll get a generic persistence failure, and waste a good deal of time trying to track it down, like I did. Here is the reference page that helped me overcome this challenge:

http://wiki.eclipse.org/EclipseLink/Examples/JPA/PrimaryKey#Using_Sequence_Objects

Also, to give context, here is what we're using:

Java 7 Glassfish 3.1 PostgreSQL 9.1 PrimeFaces 3.2/JSF 2.1

Also, for laziness' sake, I built this in Netbeans with the wizards for generating Entities from DB, Controllers from Entities, and JSF from Entities, and the wizards (obviously) do not know how to deal with sequence-based ID columns, so you'll have to manually add these annotations.

I figured out what's the problem - it is with orientation changes. If you change camera orientation to 90 or 270 degrees than you need to swap width and height of supported sizes and all will be ok.

Also surface view should lie in a frame layout and have center gravity.

Here is example on C# (Xamarin):

public void SurfaceChanged(ISurfaceHolder holder, Android.Graphics.Format format, int width, int height)
{
    _camera.StopPreview();

    // find best supported preview size

    var parameters = _camera.GetParameters();
    var supportedSizes = parameters.SupportedPreviewSizes;
    var bestPreviewSize = supportedSizes
        .Select(x => new { Width = x.Height, Height = x.Width, Original = x }) // HACK swap height and width because of changed orientation to 90 degrees
        .OrderBy(x => Math.Pow(Math.Abs(x.Width - width), 3) + Math.Pow(Math.Abs(x.Height - height), 2))
        .First();

    if (height == bestPreviewSize.Height && width == bestPreviewSize.Width)
    {
        // start preview if best supported preview size equals current surface view size

        parameters.SetPreviewSize(bestPreviewSize.Original.Width, bestPreviewSize.Original.Height);
        _camera.SetParameters(parameters);
        _camera.StartPreview();
    }
    else
    {
        // if not than change surface view size to best supported (SurfaceChanged will be called once again)

        var layoutParameters = _surfaceView.LayoutParameters;
        layoutParameters.Width = bestPreviewSize.Width;
        layoutParameters.Height = bestPreviewSize.Height;
        _surfaceView.LayoutParameters = layoutParameters;
    }
}

Pay attention that camera parameters should be set as original size (not swapped), and surface view size should be swapped.

While this is not a direct answer to Devang's question I believe that the below macro can be very helpful to people looking to log BOOLs. This will log out the value of the bool as well as automatically labeling it with the name of the variable.

#define LogBool(BOOLVARIABLE) NSLog(@"%s: %@",#BOOLVARIABLE, BOOLVARIABLE ? @"YES" : @"NO" )

BOOL success = NO;
LogBool(success); // Prints out 'success: NO' to the console

success = YES;
LogBool(success); // Prints out 'success: YES' to the console

We had the same error deploying a report to SSRS in our PROD environment. It was found the problem could even be reproduced with a “use ” statement. The solution was to re-sync the user's GUID account reference with the database in question (i.e., using "sp_change_users_login" like you would after restoring a db). A stock (cursor driven) script to re-sync all accounts is attached:

USE <your database>
GO

-------- Reset SQL user account guids ---------------------
DECLARE @UserName nvarchar(255) 
DECLARE orphanuser_cur cursor for 
      SELECT UserName = su.name 
      FROM sysusers su
      JOIN sys.server_principals sp ON sp.name = su.name
      WHERE issqluser = 1 AND
            (su.sid IS NOT NULL AND su.sid <> 0x0) AND
            suser_sname(su.sid) is null 
      ORDER BY su.name 

OPEN orphanuser_cur 
FETCH NEXT FROM orphanuser_cur INTO @UserName 

WHILE (@@fetch_status = 0)
BEGIN 
--PRINT @UserName + ' user name being resynced' 
exec sp_change_users_login 'Update_one', @UserName, @UserName 
FETCH NEXT FROM orphanuser_cur INTO @UserName 
END

Also the $wshell = New-Object -ComObject wscript.shell; helped a script that was running in the background, it worked fine with just but adding $wshell. fixed it from running as background! [Microsoft.VisualBasic.Interaction]::AppActivate("App Name")

  public double RoundDown(double number, int decimalPlaces)
        {
            return Math.Floor(number * Math.Pow(10, decimalPlaces)) / Math.Pow(10, decimalPlaces);
        }

JDK >= 1.8

I agree with all the answers above. There is also a nice way with Java 8 Streams:

int[] subArr = IntStream.range(startInclusive, endExclusive)
                        .map(i -> src[i])
                        .toArray();

The benefit about this is, it can be useful for many different types of "src" array and helps to improve writing pipeline operations on the stream.

Not particular about this question, but for example, if the source array was double[] and we wanted to take average() of the sub-array:

double avg = IntStream.range(startInclusive, endExclusive)
                    .mapToDouble(index -> src[index])
                    .average()
                    .getAsDouble();

In iPhone iOS6 and from Android ICS onwards, HTML5 has the following tag which allows you to take pictures from your device:

 <input type="file" accept="image/*" capture="camera">

Capture can take values like camera, camcorder and audio.

I think this tag will definitely not work in iOS5, not sure about it.

Supplemental Answer

When I first saw %1$s and %2$d in the accepted answer, it made no sense. Here is a little more explanation.

They are called format specifiers. In the xml string they are in the form of

%[parameter_index$][format_type] 

• %: The percent sign marks the beginning of the format specifier.
• parameter index: This is a number followed by a dollar sign. If you had three parameters that you wanted to insert into the string, then they would be called 1$, 2$, and 3$. The order you place them in the resource string doesn't matter, only the order that you supply the parameters.

• format type: There are a lot of ways that you can format things (see the documentation). Here are some common ones:

  • s string
  • d decimal integer
  • f floating point number

Example

We will create the following formatted string where the gray parts are inserted programmatically.

My sister Mary is 12 years old.

string.xml

<string name="my_xml_string">My sister %1$s is %2$d years old.</string>

MyActivity.java

String myString = "Mary";
int myInt = 12;
String formatted = getString(R.string.my_xml_string, myString, myInt);

Notes

• I could use getString because I was in an Activity. You can use context.getResources().getString(...) if it is not available.
• String.format() will also format a String.
• The 1$ and 2$ terms don't need to be used in that order. That is, 2$ can come before 1$. This is useful when internationalizing an app for languages that use a different word order.
• You can use a format specifier like %1$s multiple times in the xml if you want to repeat it.
• Use %% to get the actual % character.
• For more details read the following helpful tutorial: Android SDK Quick Tip: Formatting Resource Strings

The Expires entity-header field gives the date/time after which the response is considered stale.The Cache-control:maxage field gives the age value (in seconds) bigger than which response is consider stale.

Althought above header field give a mechanism to client to decide whether to send request to the server. In some condition, the client send a request to sever and the age value of response is bigger then the maxage value ,dose it means server needs to send the resource to client? Maybe the resource never changed.

In order to resolve this problem, HTTP1.1 gives last-modifided head. The server gives the last modified date of the response to client. When the client need this resource, it will send If-Modified-Since head field to server. If this date is before the modified date of the resouce, the server will sends the resource to client and gives 200 code.Otherwise,it will returns 304 code to client and this means client can use the resource it cached.

Thanks everyone who have answered.I have seen all answers and to try to make it easy for everyone

Step 1: Type edit environment and select the option shown

Step 2: Select Path and click on edit

Step 3: In the end add the below statement(you can avoid the first ; if its already there)

;C:\Program Files\Git\bin\git.exe;C:\Program Files\Git\cmd

Step 4:- Click on ok

Step 5 **:- One of the important step which is highlighted by one of the users. thanks to him. Please, **CLOSE command prompt and REOPEN then try to write git.

**

• Close command prompt and restart before trying the below command

Here is the magic

You can extract all the information from the DbEntityValidationException with the following code (you need to add the namespaces: System.Data.Entity.Validation and System.Diagnostics to your using list):

catch (DbEntityValidationException dbEx)
{
    foreach (var validationErrors in dbEx.EntityValidationErrors)
    {
        foreach (var validationError in validationErrors.ValidationErrors)
        {
            Trace.TraceInformation("Property: {0} Error: {1}", 
                                    validationError.PropertyName, 
                                    validationError.ErrorMessage);
        }
    }
}

DesiredCapabilities are options that you can use to customize and configure a browser session.

You can read more about them here!

"location" directive should be inside a 'server' directive, e.g.

server {
    listen       8765;

    location / {
        resolver 8.8.8.8;
        proxy_pass http://$http_host$uri$is_args$args;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }
}

in your main layout put this in the head at the bottom of everything

@stack('styles')

and in your view put this

@push('styles')

    <link rel="stylesheet" href="{{ asset('css/app.css') }}">

@endpush

basically a placeholder so the links will appear on your main layout, and you can see custom css files on different pages

Logically there are no difference at all. Performance-wise there are -typically, on most DBMSes- no difference at all.

In case above-accepted answer did not work, try below solution. You can use it for port 8080 or for any other ports.

sudo lsof -i tcp:3000 

Replace 3000 with whichever port you want. Run below command to kill that process.

sudo kill -9 PID

PID is process ID you want to kill.

Below is the output of commands on mac Terminal.

If you just happen to have a Map with Integer keys you cannot change, you could write a custom EL function to convert a Long to Integer. This would allow you to do something like:

<c:out value="${map[myLib:longToInteger(1)]}"/>

 SELECT *
   FROM mytable
  WHERE (start_date, end_date) OVERLAPS ('2012-01-01'::DATE, '2012-04-12'::DATE);

Datetime functions is the relevant section in the docs.

If you're using Python3.x input will return a string,so you should use int method to convert string to integer.

Python3 Input

If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. When EOF is read, EOFError is raised.

By the way,it's a good way to use try catch if you want to convert string to int:

try:
  i = int(s)
except ValueError as err:
  pass 

Hope this helps.

In Java, remove leading character only if it is a certain character

Use the Java ternary operator to quickly check if your character is there before removing it. This strips the leading character only if it exists, if passed a blank string, return blankstring.

String header = "";
header = header.startsWith("#") ? header.substring(1) : header;
System.out.println(header);

header = "foobar";
header = header.startsWith("#") ? header.substring(1) : header;
System.out.println(header);

header = "#moobar";
header = header.startsWith("#") ? header.substring(1) : header;
System.out.println(header);

Prints:

blankstring
foobar
moobar

Java, remove all the instances of a character anywhere in a string:

String a = "Cool";
a = a.replace("o","");
//variable 'a' contains the string "Cl"

Java, remove the first instance of a character anywhere in a string:

String b = "Cool";
b = b.replaceFirst("o","");
//variable 'b' contains the string "Col"

Not sure why they removed the option to just right click on the database and restore like you could in SQL Server Management Studio 2008 and earlier, but as mentioned above you can restore from a .BAK file with:

RESTORE DATABASE YourDB FROM DISK = 'D:BackUpYourBaackUpFile.bak' WITH REPLACE

But you will want WITH REPLACE instead of WITH RESTORE if your moving it from one server to another.

$.each( { name: "John", lang: "JS" }, function(i, n){
    alert( "Name: " + i + ", Value: " + n );
});

each

double a = 1.000001;
double b = 0.000001;

System.out.println( a.compareTo(b) );

Returns:

• -1 : 'a' is numerically less than 'b'.

• 0 : 'a' is equal to 'b'.

• 1 : 'a' is greater than 'b'.

you can create a List[] and initialize them by for loop. it compiles without errors:

List<e>[] l;
for(int i = 0; i < l.length; i++){
    l[i] = new ArrayList<e>();
}

it works with arrayList[] l as well.

Yes. Empty or incomplete headers or response body typically caused by broken connections or server side crash can cause 502 errors if accessed via a gateway or proxy.

Part of the problem here is that the strings usually used to represent timezones are not actually unique. "EST" only means "America/New_York" to people in North America. This is a limitation in the C time API, and the Python solution is… to add full tz features in some future version any day now, if anyone is willing to write the PEP.

You can format and parse a timezone as an offset, but that loses daylight savings/summer time information (e.g., you can't distinguish "America/Phoenix" from "America/Los_Angeles" in the summer). You can format a timezone as a 3-letter abbreviation, but you can't parse it back from that.

If you want something that's fuzzy and ambiguous but usually what you want, you need a third-party library like dateutil.

If you want something that's actually unambiguous, just append the actual tz name to the local datetime string yourself, and split it back off on the other end:

d = datetime.datetime.now(pytz.timezone("America/New_York"))
dtz_string = d.strftime(fmt) + ' ' + "America/New_York"

d_string, tz_string = dtz_string.rsplit(' ', 1)
d2 = datetime.datetime.strptime(d_string, fmt)
tz2 = pytz.timezone(tz_string)

print dtz_string 
print d2.strftime(fmt) + ' ' + tz_string

Or… halfway between those two, you're already using the pytz library, which can parse (according to some arbitrary but well-defined disambiguation rules) formats like "EST". So, if you really want to, you can leave the %Z in on the formatting side, then pull it off and parse it with pytz.timezone() before passing the rest to strptime.

If you use ng-model, you don't want to also use ng-checked. Instead just initialize the model variable to true. Normally you would do this in a controller that is managing your page (add one). In your fiddle I just did the initialization in an ng-init attribute for demonstration purposes.

http://jsfiddle.net/UTULc/

<div ng-app="">
  Send to Office: <input type="checkbox" ng-model="checked" ng-init="checked=true"><br/>
  <select id="transferTo" ng-disabled="checked">
    <option>Tech1</option>
    <option>Tech2</option>
  </select>
</div>

This worked fine with me url:http://example.com/rest/muqsith/get-file?filePath=C:\Users\I066807\Desktop\test.xml

@GET
@Produces({ MediaType.APPLICATION_OCTET_STREAM })
@Path("/get-file")
public Response getFile(@Context HttpServletRequest request){
   String filePath = request.getParameter("filePath");
   if(filePath != null && !"".equals(filePath)){
        File file = new File(filePath);
        StreamingOutput stream = null;
        try {
        final InputStream in = new FileInputStream(file);
        stream = new StreamingOutput() {
            public void write(OutputStream out) throws IOException, WebApplicationException {
                try {
                    int read = 0;
                        byte[] bytes = new byte[1024];

                        while ((read = in.read(bytes)) != -1) {
                            out.write(bytes, 0, read);
                        }
                } catch (Exception e) {
                    throw new WebApplicationException(e);
                }
            }
        };
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
        return Response.ok(stream).header("content-disposition","attachment; filename = "+file.getName()).build();
        }
    return Response.ok("file path null").build();

I did a little research and was able to write this code:

strbody = "<BODY style=font-size:11pt;font-family:Calibri>Good Morning;<p>We have completed our main aliasing process for today.  All assigned firms are complete.  Please feel free to respond with any questions.<p>Thank you.</BODY>"

apparently by setting the "font-size=11pt" instead of setting the font size <font size=5>, It allows you to select a specific font size like you normally would in a text editor, as opposed to selecting a value from 1-7 like my code was originally.

This link from simpLE MAn gave me some good info.

The second one is fastest. Using strlen will be close if the string is indeed empty, but strlen will always iterate through every character of the string, so if it is not empty, it will do much more work than you need it to.

As James mentioned, the third option wipes the string out before checking, so the check will always succeed but it will be meaningless.

Ok, I'm probably late to the party, BUT...

THERE'S NO NEED TO RESIZE THE COLUMN IN YOUR CASE!

Postgres, unlike some other databases, is smart enough to only use just enough space to fit the string (even using compression for longer strings), so even if your column is declared as VARCHAR(255) - if you store 40-character strings in the column, the space usage will be 40 bytes + 1 byte of overhead.

The storage requirement for a short string (up to 126 bytes) is 1 byte plus the actual string, which includes the space padding in the case of character. Longer strings have 4 bytes of overhead instead of 1. Long strings are compressed by the system automatically, so the physical requirement on disk might be less. Very long values are also stored in background tables so that they do not interfere with rapid access to shorter column values.

(http://www.postgresql.org/docs/9.0/interactive/datatype-character.html)

The size specification in VARCHAR is only used to check the size of the values which are inserted, it does not affect the disk layout. In fact, VARCHAR and TEXT fields are stored in the same way in Postgres.

You can use the with_fileglob loop for this:

- copy:
    src: "{{ item }}"
    dest: /etc/fooapp/
    owner: root
    mode: 600
  with_fileglob:
    - /playbooks/files/fooapp/*

[Edit] After reviewing the Mongoose documentation, it looks like you can send each query result as a separate chunk; the web server uses chunked transfer encoding by default so all you have to do is wrap an array around the items to make it a valid JSON object.

Roughly (untested):

app.get('/users/:email/messages/unread', function(req, res, next) {
  var firstItem=true, query=MessageInfo.find(/*...*/);
  res.writeHead(200, {'Content-Type': 'application/json'});
  query.each(function(docs) {
    // Start the JSON array or separate the next element.
    res.write(firstItem ? (firstItem=false,'[') : ',');
    res.write(JSON.stringify({ msgId: msg.fileName }));
  });
  res.end(']'); // End the JSON array and response.
});

Alternatively, as you mention, you can simply send the array contents as-is. In this case the response body will be buffered and sent immediately, which may consume a large amount of additional memory (above what is required to store the results themselves) for large result sets. For example:

// ...
var query = MessageInfo.find(/*...*/);
res.writeHead(200, {'Content-Type': 'application/json'});
res.end(JSON.stringify(query.map(function(x){ return x.fileName })));

Sessions are stored on the server and are set from server side code, not client side code such as JavaScript.

What you want is a cookie, someone's given a brilliant explanation in this Stack Overflow question here: How do I set/unset cookie with jQuery?

You could potentially use sessions and set/retrieve them with jQuery and AJAX, but it's complete overkill if Cookies will do the trick.

Strings are immutable. But you can convert them to a list, which is mutable, and then convert the list back to a string after you've changed it.

s = "this is a string"

l = list(s)  # convert to list

l[1] = ""    # "delete" letter h (the item actually still exists but is empty)
l[1:2] = []  # really delete letter h (the item is actually removed from the list)
del(l[1])    # another way to delete it

p = l.index("a")  # find position of the letter "a"
del(l[p])         # delete it

s = "".join(l)  # convert back to string

You can also create a new string, as others have shown, by taking everything except the character you want from the existing string.

1.Update project

Right Click on your project maven > update project

2.Build project

Right Click on your project again. run as > Maven build

If you have not created a “Run configuration” yet, it will open a new configuration with some auto filled values.

You can change the name. "Base directory" will be a auto filled value for you. Keep it as it is. Give maven command to ”Goals” fields.

i.e, “clean install” for building purpose

Click apply

Click run.

3.Run project on tomcat

Right Click on your project again. run as > Run-Configuration. It will open Run-Configuration window for you.

Right Click on “Maven Build” from the right side column and Select “New”. It will open a blank configuration for you.

Change the name as you want. For the base directory field you can choose values using 3 buttons(workspace,FileSystem,Variables). You can also copy and paste the auto generated value from previously created Run-configuration. Give the Goals as “tomcat:run”. Click apply. Click run.

If you want to get more clear idea with snapshots use the following link.

(I hope this answer will help someone come after the topic of the question)

Python doesn't have a preprocessor, nor does it have constants in the sense that they can't be changed - you can always change (nearly, you can emulate constant object properties, but doing this for the sake of constant-ness is rarely done and not considered useful) everything. When defining a constant, we define a name that's upper-case-with-underscores and call it a day - "We're all consenting adults here", no sane man would change a constant. Unless of course he has very good reasons and knows exactly what he's doing, in which case you can't (and propably shouldn't) stop him either way.

But of course you can define a module-level name with a value and use it in another module. This isn't specific to constants or anything, read up on the module system.

# a.py
MY_CONSTANT = ...

# b.py
import a
print a.MY_CONSTANT

You have to set the Authorization field in the header.

It contains the authentication type Basic in this case and the username:password combination which gets encoded in Base64:

var username = 'Test';
var password = '123';
var auth = 'Basic ' + Buffer.from(username + ':' + password).toString('base64');
// new Buffer() is deprecated from v6

// auth is: 'Basic VGVzdDoxMjM='

var header = {'Host': 'www.example.com', 'Authorization': auth};
var request = client.request('GET', '/', header);

I think you could do it using a specs file.

Under MinGW you could run
gcc -dumpspecs > specs

Where it says

*cpp:
%{posix:-D_POSIX_SOURCE} %{mthreads:-D_MT}

You change it to

*cpp:
%{posix:-D_POSIX_SOURCE} %{mthreads:-D_MT} -std=c++11

And then place it in
/mingw/lib/gcc/mingw32/<version>/specs

I'm sure you could do the same without a MinGW build. Not sure where to place the specs file though.

The folder is probably either /gcc/lib/ or /gcc/.

use JSON.stringify(userData) to coverty json object to string.

var dataStore = $.cookie("basket-data", JSON.stringify($("#ArticlesHolder").data()));

and for getting back from cookie use JSON.parse()

var data=JSON.parse($.cookie("basket-data"))

Your compiled classes may need to be recompiled from the source with the new jars.

Try running "mvn clean" and then rebuild

Other answers here discuss the various problems with trying to do this. I thought I'd show how you might try this in case you wanted to learn by doing it yourself.

You can connect to an mail server via telnet to ask whether an email address exists. Here's an example of testing an email address for stackoverflow.com:

C:\>nslookup -q=mx stackoverflow.com
Non-authoritative answer:
stackoverflow.com       MX preference = 40, mail exchanger = STACKOVERFLOW.COM.S9B2.PSMTP.com
stackoverflow.com       MX preference = 10, mail exchanger = STACKOVERFLOW.COM.S9A1.PSMTP.com
stackoverflow.com       MX preference = 20, mail exchanger = STACKOVERFLOW.COM.S9A2.PSMTP.com
stackoverflow.com       MX preference = 30, mail exchanger = STACKOVERFLOW.COM.S9B1.PSMTP.com

Lines prefixed with numeric codes are responses from the SMTP server. I added some blank lines to make it more readable.

Many mail servers will not return this information as a means to prevent against email address harvesting by spammers, so you cannot rely on this technique. However you may have some success at cleaning out some obviously bad email addresses by detecting invalid mail servers, or having recipient addresses rejected as above.

Note too that mail servers may blacklist you if you make too many requests of them.

In PHP I believe you can use fsockopen, fwrite and fread to perform the above steps programmatically:

$smtp_server = fsockopen("STACKOVERFLOW.COM.S9A1.PSMTP.com", 25, $errno, $errstr, 30);
fwrite($smtp_server, "helo hi\r\n");
fwrite($smtp_server, "mail from: <[email protected]>\r\n");
fwrite($smtp_server, "rcpt to: <[email protected]>\r\n");

If I understand what you need, try this:

SELECT id, pass, AVG(val) AS val_1 
FROM data_r1 
GROUP BY id, pass;

Or, if you want just one row for every id, this:

SELECT d1.id,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 1) as val_1,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 2) as val_2,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 3) as val_3,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 4) as val_4,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 5) as val_5,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 6) as val_6,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 7) as val_7
from data_r1 d1
GROUP BY d1.id

GISTS The Gist is an outstanding service provided by GitHub. Using this service, you can share your work publically or privately. You can share a single file, articles, full applications or source code etc.

The GitHub is much more than just Gists. It provides immense services to group together a project or programs digital resources in a centralized location called repository and share among stakeholder. The GitHub repository will hold or maintain the multiple version of the files or history of changes and you can retrieve a specific version of a file when you want. Whereas gist will create each post as a new repository and will maintain the history of the file.

I do interviews for work and i would look unfavourably on your answer aswell (sorry but im very honest). It does sound like you've read about the difference and revised an answer but perhaps you have never used it in practice.

A good explanation as to why you would use each can be far better than having a precise explanation of the difference. Employers ultimatley want programers to do things not know them which can be hard to demonstrate in an interview. The answer you gave would be good if applying for a technical or documentation based job but not a developers role.

Best of luck with interviews in the future.

Also my answer to this question is more about interview technique rather than the technical material youve provided. Perhaps consider reading about it. https://workplace.stackexchange.com/ can be an excellent place for this sort of thing.

First you should know, how much memory is allocated when you define and allocate memory in below case.

   typedef struct person{
       char firstName[100], surName[51]
  } PERSON;
  PERSON *testPerson = (PERSON*) malloc(sizeof(PERSON));

1) The sizeof(PERSON) now returns 151 bytes (Doesn't include padding)

2) The memory of 151 bytes is allocated in heap.

3) To free, call free(testPerson).

but If you declare your structure as

  typedef struct person{
      char *firstName, *surName;
  } PERSON;
  PERSON *testPerson = (PERSON*) malloc(sizeof(PERSON));

then

1) The sizeof(PERSON) now returns 8 bytes (Doesn't include padding)

2) Need to allocate memory for firstName and surName by calling malloc() or calloc(). like

        testPerson->firstName = (char *)malloc(100);

3) To free, first free the members in the struct than free the struct. i.e, free(testPerson->firstName); free(testPerson->surName); free(testPerson);

In Addition you can use XPath selector in the following way (easy way to select specific nodes):

XmlDocument doc = new XmlDocument();
doc.Load("test.xml");

var found = doc.DocumentElement.SelectNodes("//book[@title='Barry Poter']"); // select all Book elements in whole dom, with attribute title with value 'Barry Poter'

// Retrieve your data here or change XML here:
foreach (XmlNode book in nodeList)
{
  book.InnerText="The story began as it was...";
}

Console.WriteLine("Display XML:");
doc.Save(Console.Out);

the documentation

$(function(){

    $(selector).click();

});

HttpHandler Example,

HTTP Handler in ASP.NET 2.0

A handler is responsible for fulfilling requests from a browser. Requests that a browser manages are either handled by file extension or by calling the handler directly.The low level Request and Response API to service incoming Http requests are Http Handlers in Asp.Net. All handlers implement the IHttpHandler interface, which is located in the System.Web namespace. Handlers are somewhat analogous to Internet Server Application Programming Interface (ISAPI) extensions.

You implement the IHttpHandler interface to create a synchronous handler and the IHttpAsyncHandler interface to create an asynchronous handler. The interfaces require you to implement the ProcessRequest method and the IsReusable property. The ProcessRequest method handles the actual processing for requests made, while the Boolean IsReusable property specifies whether your handler can be pooled for reuse to increase performance or whether a new handler is required for each request.

The .ashx file extension is reserved for custom handlers. If you create a custom handler with a file name extension of .ashx, it will automatically be registered within IIS and ASP.NET. If you choose to use an alternate file extension, you will have to register the extension within IIS and ASP.NET. The advantage of using an extension other than .ashx is that you can assign multiple file extensions to one handler.

Configuring HTTP Handlers

The configuration section handler is responsible for mapping incoming URLs to the IHttpHandler or IHttpHandlerFactory class. It can be declared at the computer, site, or application level. Subdirectories inherit these settings. Administrators use the tag directive to configure the section. directives are interpreted and processed in a top-down sequential order. Use the following syntax for the section handler:

Creating HTTP Handlers

To create an HTTP handler, you must implement the IHttpHandler interface. The IHttpHandler interface has one method and one property with the following signatures: void ProcessRequest(HttpContext); bool IsReusable {get;}

I use one Factory module that contains one (or more) constructor per class which calls the Init member of each class.

For example a Point class:

Class Point
Private X, Y
Sub Init(X, Y)
  Me.X = X
  Me.Y = Y
End Sub

A Line class

Class Line
Private P1, P2
Sub Init(Optional P1, Optional P2, Optional X1, Optional X2, Optional Y1, Optional Y2)
  If P1 Is Nothing Then
    Set Me.P1 = NewPoint(X1, Y1)
    Set Me.P2 = NewPoint(X2, Y2)
  Else
    Set Me.P1 = P1
    Set Me.P2 = P2
  End If
End Sub

And a Factory module:

Module Factory
Function NewPoint(X, Y)
  Set NewPoint = New Point
  NewPoint.Init X, Y
End Function

Function NewLine(Optional P1, Optional P2, Optional X1, Optional X2, Optional Y1, Optional Y2)
  Set NewLine = New Line
  NewLine.Init P1, P2, X1, Y1, X2, Y2
End Function

Function NewLinePt(P1, P2)
  Set NewLinePt = New Line
  NewLinePt.Init P1:=P1, P2:=P2
End Function

Function NewLineXY(X1, Y1, X2, Y2)
  Set NewLineXY = New Line
  NewLineXY.Init X1:=X1, Y1:=Y1, X2:=X2, Y2:=Y2
End Function

One nice aspect of this approach is that makes it easy to use the factory functions inside expressions. For example it is possible to do something like:

D = Distance(NewPoint(10, 10), NewPoint(20, 20)

or:

D = NewPoint(10, 10).Distance(NewPoint(20, 20))

It's clean: the factory does very little and it does it consistently across all objects, just the creation and one Init call on each creator.

And it's fairly object oriented: the Init functions are defined inside the objects.

EDIT

I forgot to add that this allows me to create static methods. For example I can do something like (after making the parameters optional):

NewLine.DeleteAllLinesShorterThan 10

Unfortunately a new instance of the object is created every time, so any static variable will be lost after the execution. The collection of lines and any other static variable used in this pseudo-static method must be defined in a module.

You can solve this by increasing the maximum request length in your web.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.web>
        <httpRuntime maxRequestLength="102400" />
    </system.web>
</configuration>

The example above is for a 100Mb limit.

My table is named Genre with the 3 columns of Id, Name and SortOrder

The code that I used is as:

SET IDENTITY_INSERT Genre ON

INSERT INTO Genre(Id, Name, SortOrder)VALUES (12,'Moody Blues', 20) 

Try this!

this.selectedObjectList = [{id:1}, {id:2}, {id:3}]
this.allObjectList = [{id:1}, {id:2}, {id:3}, {id:4}, {id:5}]
let newList = this.allObjectList.filter(e => this.selectedObjectList.find(a => e.id == a.id))
this.selectedObjectList = newList

I think you are confused about how the compiler puts things together. When you use -c flag, i.e. no linking is done, the input is C++ code, and the output is object code. The .o files thus don't mix with -c, and compiler warns you about that. Symbols from object file are not moved to other object files like that.

All object files should be on the final linker invocation, which is not the case here, so linker (called via g++ front-end) complains about missing symbols.

Here's a small example (calling g++ explicitly for clarity):

PROG ?= myprog
OBJS = worker.o main.o

all: $(PROG)

.cpp.o:
        g++ -Wall -pedantic -ggdb -O2 -c -o $@ $<

$(PROG): $(OBJS)
        g++ -Wall -pedantic -ggdb -O2 -o $@ $(OBJS)

There's also makedepend utility that comes with X11 - helps a lot with source code dependencies. You might also want to look at the -M gcc option for building make rules.

YapDi is a relatively new python module that popped up in Hacker News. Looks pretty useful, can be used to convert a python script into daemon mode from inside the script.

I had another problem not described here, which drove me nuts.

class MyModel(models.Model):
    name = models.CharField(max_length=64, null=True)  # works
    language_code = models.CharField(max_length=2, default='en')  # works
    is_dumb = models.BooleanField(default=False),  # doesn't work

I had a trailing ',' in one line perhaps from copy&paste. The line with is_dumb doesn't created a model migration with './manage.py makemigrations' but also didn't throw an error. After removing the ',' it worked as expected.

So be careful when you do copy&paste :-)

Bruno is right on track. I've done extensive research and if you want to set variables that are available in all GUI applications, your only option is /etc/launchd.conf.

Please note that environment.plist does not work for applications launched via Spotlight. This is documented by Steve Sexton here.

1. Open a terminal prompt

2. Type sudo vi /etc/launchd.conf (note: this file might not yet exist)

3. Put contents like the following into the file

   # Set environment variables here so they are available globally to all apps
   # (and Terminal), including those launched via Spotlight.
   #
   # After editing this file run the following command from the terminal to update
   # environment variables globally without needing to reboot.
   # NOTE: You will still need to restart the relevant application (including
   # Terminal) to pick up the changes!
   # grep -E "^setenv" /etc/launchd.conf | xargs -t -L 1 launchctl
   #
   # See http://www.digitaledgesw.com/node/31
   # and http://stackoverflow.com/questions/135688/setting-environment-variables-in-os-x/
   #
   # Note that you must hardcode the paths below, don't use environment variables.
   # You also need to surround multiple values in quotes, see MAVEN_OPTS example below.
   #
   setenv JAVA_VERSION 1.6
   setenv JAVA_HOME /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home
   setenv GROOVY_HOME /Applications/Dev/groovy
   setenv GRAILS_HOME /Applications/Dev/grails
   setenv NEXUS_HOME /Applications/Dev/nexus/nexus-webapp
   setenv JRUBY_HOME /Applications/Dev/jruby
   
   setenv ANT_HOME /Applications/Dev/apache-ant
   setenv ANT_OPTS -Xmx512M
   
   setenv MAVEN_OPTS "-Xmx1024M -XX:MaxPermSize=512m"
   setenv M2_HOME /Applications/Dev/apache-maven
   
   setenv JMETER_HOME /Applications/Dev/jakarta-jmeter
   

4. Save your changes in vi and reboot your Mac. Or use the grep/xargs command which is shown in the code comment above.

5. Prove that your variables are working by opening a Terminal window and typing export and you should see your new variables. These will also be available in IntelliJ IDEA and other GUI applications you launch via Spotlight.

Google's cppclean (links to: download, documentation) can find several categories of C++ problems, and it can now find superfluous #includes.

There's also a Clang-based tool, include-what-you-use, that can do this. include-what-you-use can even suggest forward declarations (so you don't have to #include so much) and optionally clean up your #includes for you.

Current versions of Eclipse CDT also have this functionality built in: going under the Source menu and clicking Organize Includes will alphabetize your #include's, add any headers that Eclipse thinks you're using without directly including them, and comments out any headers that it doesn't think you need. This feature isn't 100% reliable, however.

I'm afraid there is no "better" way to get this size, however it's not that much pain.

Of course your code should be safe for both binary/mono images as well as multi-channel ones, but the principal dimensions of the image always come first in the numpy array's shape. If you opt for readability, or don't want to bother typing this, you can wrap it up in a function, and give it a name you like, e.g. cv_size:

import numpy as np
import cv2

# ...

def cv_size(img):
    return tuple(img.shape[1::-1])

If you're on a terminal / ipython, you can also express it with a lambda:

>>> cv_size = lambda img: tuple(img.shape[1::-1])
>>> cv_size(img)
(640, 480)

Writing functions with def is not fun while working interactively.

Edit

Originally I thought that using [:2] was OK, but the numpy shape is (height, width[, depth]), and we need (width, height), as e.g. cv2.resize expects, so - we must use [1::-1]. Even less memorable than [:2]. And who remembers reverse slicing anyway?

This solution is for windows:

1. Open command prompt in Administrator Mode.
2. Goto path: C:\Program Files\MySQL\MySQL Server 5.6\bin
3. Run below command: mysqldump -h 127.0.01 -u root -proot db table1 table2 > result.sql

This way you can Create NSArray, NSMutableArray.

NSArray keys =[NSArray arrayWithObjects:@"key1",@"key2",@"key3",nil];

NSArray objects =[NSArray arrayWithObjects:@"value1",@"value2",@"value3",nil];

Nothing will be faster than a simple loop. You can mix-and-match some array functions to do it, but they'll just be implemented as a loop too.

function whatever($array, $key, $val) {
    foreach ($array as $item)
        if (isset($item[$key]) && $item[$key] == $val)
            return true;
    return false;
}

I don't understand how can datenwolf`s index generation can be correct. But still I find his solution rather clear. This is what I get after some thinking:

inline void push_indices(vector<GLushort>& indices, int sectors, int r, int s) {
    int curRow = r * sectors;
    int nextRow = (r+1) * sectors;

    indices.push_back(curRow + s);
    indices.push_back(nextRow + s);
    indices.push_back(nextRow + (s+1));

    indices.push_back(curRow + s);
    indices.push_back(nextRow + (s+1));
    indices.push_back(curRow + (s+1));
}

void createSphere(vector<vec3>& vertices, vector<GLushort>& indices, vector<vec2>& texcoords,
             float radius, unsigned int rings, unsigned int sectors)
{
    float const R = 1./(float)(rings-1);
    float const S = 1./(float)(sectors-1);

    for(int r = 0; r < rings; ++r) {
        for(int s = 0; s < sectors; ++s) {
            float const y = sin( -M_PI_2 + M_PI * r * R );
            float const x = cos(2*M_PI * s * S) * sin( M_PI * r * R );
            float const z = sin(2*M_PI * s * S) * sin( M_PI * r * R );

            texcoords.push_back(vec2(s*S, r*R));
            vertices.push_back(vec3(x,y,z) * radius);
            push_indices(indices, sectors, r, s);
        }
    }
}

Suppose n is not a prime number (greater than 1). So there are numbers a and b such that

n = ab      (1 < a <= b < n)

By multiplying the relation a<=b by a and b we get:

a^2 <= ab
 ab <= b^2

Therefore: (note that n=ab)

a^2 <= n <= b^2

Hence: (Note that a and b are positive)

a <= sqrt(n) <= b

So if a number (greater than 1) is not prime and we test divisibility up to square root of the number, we will find one of the factors.

Quite a few applications seem to implement Steganography on JPEG, so it's feasible:

Here's an article regarding a relevant algorithm (PM1) to get you started:

You can have both formats as an argument to the function date():

date("d-m-Y H:i:s")

Check the manual for more info : http://php.net/manual/en/function.date.php

As pointed out by @ThomasVdBerge to display minutes you need the 'i' character

For cases where you also wish to have the option of setting 'b' to None:

def p(self, **kwargs):
    b = kwargs.get('b', self.a)
    print b

It's a pity that both of the answers analyze the problem but didn't give a direct answer. Let's see the code.

Z = np.array([1.0, 1.0, 1.0, 1.0])  

def func(TempLake, Z):
    A = TempLake
    B = Z
    return A * B
Nlayers = Z.size
N = 3
TempLake = np.zeros((N+1, Nlayers))
kOUT = np.zeros(N + 1)

for i in xrange(N):
    # store the i-th result of
    # function "func" in i-th item in kOUT
    kOUT[i] = func(TempLake[i], Z)

The error shows that you set the ith item of kOUT(dtype:int) into an array. Here every item in kOUT is an int, can't directly assign to another datatype. Hence you should declare the data type of kOUT when you create it. For example, like:

Change the statement below:

kOUT = np.zeros(N + 1)

into:

kOUT = np.zeros(N + 1, dtype=object)

or:

kOUT = np.zeros((N + 1, N + 1))

All code:

import numpy as np
Z = np.array([1.0, 1.0, 1.0, 1.0])

def func(TempLake, Z):
    A = TempLake
    B = Z
    return A * B

Nlayers = Z.size
N = 3
TempLake = np.zeros((N + 1, Nlayers))

kOUT = np.zeros(N + 1, dtype=object)
for i in xrange(N):
    kOUT[i] = func(TempLake[i], Z)

Hope it can help you.

Loop like

foreach (GridViewRow row in grid.Rows)
{
   if (((CheckBox)row.FindControl("chkboxid")).Checked)
   {
    //read the label            
   }            
}

Use this formula:

=100% + (Year 2/Year 1)

The logic is that you recover 100% of the negative in year 1 (hence the initial 100%) plus any excess will be a ratio against year 1.

Use this query:

SELECT USER();

Or

SELECT CURRENT_USER;

You can just move node_modules into a / folder.

How it works

FROM node:0.12

WORKDIR /worker

COPY package.json /worker/
RUN npm install \
  && mv node_modules /node_modules

COPY . /worker/

Given your container width 600px.

If you want only bigger images than that to fit inside, add: CSS:

#ImageContainer img {
    max-width: 600px;
}

If you want ALL images to take the avaiable (600px) space:

#ImageContainer img {
    width: 600px;
}

There should be

$('.send_upload')

but not $('.upload')

You're using the argument as a reference but actually it's a pointer. Change vector<int>* to vector<int>&. And you should really set search4 to something before using it.

You can change the value in the XML like this:

<Button
    android:background="#FFFFFF"
     ../>

Here, you can add any other color, from the resources or hex.

Similarly, you can also change these values form the code like this:

demoButton.setBackgroundColor(Color.WHITE);

Another easy way is to make a drawable, customize the corners and shape according to your preference and set the background color and stroke of the drawable. For eg.

button_background.xml

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke android:width="2dp" android:color="#ff207d94" />
    <corners android:radius="5dp" />
    <solid android:color="#FFFFFF" />
</shape>

And then set this shape as the background of your button.

<Button
    android:background="@drawable/button_background.xml"
     ../>

Hope this helps, good luck!

Recently I found this:

ArrayList<T> yourList = Collections.list(Collections.enumeration(yourSet<T>));

Angular JS does this way.

msie = parseInt((/msie (\d+)/.exec(navigator.userAgent.toLowerCase()) || [])[1]);
if (isNaN(msie)) {
  msie = parseInt((/trident\/.*; rv:(\d+)/.exec(navigator.userAgent.toLowerCase()) || [])[1]);
}

msie will be positive number if its IE and NaN for other browser like chrome,firefox.

why ?

As of Internet Explorer 11, the user-agent string has changed significantly.

refer this :

msdn #1 msdn #2

The property pDoc.parentElement or pDoc.parentNode will get you the parent element.

Just move it :)

command line :

move "C:\Documents and Setings\$USER\project" C:\project

or just drag the folder in explorer.

Git won't care where it is - all the metadata for the repository is inside a folder called .git inside your project folder.

Honestly though, whether there is a way for it to evaluate to true or not (and as others have shown, there are multiple ways), the answer I'd be looking for, speaking as someone who has conducted hundreds of interviews, would be something along the lines of:

"Well, maybe yes under some weird set of circumstances that aren't immediately obvious to me... but if I encountered this in real code then I would use common debugging techniques to figure out how and why it was doing what it was doing and then immediately refactor the code to avoid that situation... but more importantly: I would absolutely NEVER write that code in the first place because that is the very definition of convoluted code, and I strive to never write convoluted code".

I guess some interviewers would take offense to having what is obviously meant to be a very tricky question called out, but I don't mind developers who have an opinion, especially when they can back it up with reasoned thought and can dovetail my question into a meaningful statement about themselves.

As of Excel 2019 you could do this. The "Error" at the end is the default.

I tried to use the code above but didn't work. The JSON structure returned by Google is so different and there is a very important miss in the helper function: a call to DataContractJsonSerializer.ReadObject() that actually deserializes the JSON data into the object.

Here is the code that WORKS in 2011:

using System;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Json;
using System.IO;
using System.Text;
using System.Collections.Generic;

namespace <YOUR_NAMESPACE>
{
    public class JSONHelper
    {
        public static T Deserialise<T>(string json)
        {
            T obj = Activator.CreateInstance<T>();
            MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json));
            DataContractJsonSerializer serialiser = new DataContractJsonSerializer(obj.GetType());
            obj = (T)serialiser.ReadObject(ms);
            ms.Close();
            return obj;
        }
    }

    public class Result
    {
        public string GsearchResultClass { get; set; }
        public string unescapedUrl { get; set; }
        public string url { get; set; }
        public string visibleUrl { get; set; }
        public string cacheUrl { get; set; }
        public string title { get; set; }
        public string titleNoFormatting { get; set; }
        public string content { get; set; }
    }

    public class Page
    {
        public string start { get; set; }
        public int label { get; set; }
    }

    public class Cursor
    {
        public string resultCount { get; set; }
        public Page[] pages { get; set; }
        public string estimatedResultCount { get; set; }
        public int currentPageIndex { get; set; }
        public string moreResultsUrl { get; set; }
        public string searchResultTime { get; set; }
    }

    public class ResponseData
    {
        public Result[] results { get; set; }
        public Cursor cursor { get; set; }
    }

    public class GoogleSearchResults
    {
        public ResponseData responseData { get; set; }
        public object responseDetails { get; set; }
        public int responseStatus { get; set; }
    }
}

To get the content of the first result, do:

GoogleSearchResults googleResults = new GoogleSearchResults();
googleResults = JSONHelper.Deserialise<GoogleSearchResults>(jsonData);
string contentOfFirstResult = googleResults.responseData.results[0].content;

Try this one

 public static void main(String[] args) 
{
     int x=11;
     int y=x/2; // spaces
     int z=1; // *`s

     for(int i=0;i<5;i++)
    {
         for(int j=0;j<y;j++)
        {
             System.out.print(" ");
        }
        for(int k=0;k<z;k++)
        {
            System.out.print("*");
        }

        y=y-1;
        z=z+2;
        System.out.println();  
    }

}

The head command can get the first n lines. Variations are:

head -7 file
head -n 7 file
head -7l file

which will get the first 7 lines of the file called "file". The command to use depends on your version of head. Linux will work with the first one.

To append lines to the end of the same file, use:

echo 'first line to add' >>file
echo 'second line to add' >>file
echo 'third line to add' >>file

or:

echo 'first line to add
second line to add
third line to add' >>file

to do it in one hit.

So, tying these two ideas together, if you wanted to get the first 10 lines of the input.txt file to output.txt and append a line with five "=" characters, you could use something like:

( head -10 input.txt ; echo '=====' ) > output.txt

In this case, we do both operations in a sub-shell so as to consolidate the output streams into one, which is then used to create or overwrite the output file.

You have to drop it and recreate it, but you don't have to incur the cost of revalidating the data if you don't want to.

alter table t drop constraint ck ;
alter table t add constraint ck check (n < 0) enable novalidate;

The enable novalidate clause will force inserts or updates to have the constraint enforced, but won't force a full table scan against the table to verify all rows comply.

To launch command prompt in administrator mode

1. Type cmd in Search and hold Crtl+Shift to open in administrator mode
2. Type attrib -h -r -s /s /d "location of the drive letter:" \*.*

With Java 8, the new java.time package should be used.

Objects are immutable, time zones and day light saving are taken into account.

You can create a ZonedDateTime object from an old java.util.Date object like this:

    Date date = new Date();
    ZonedDateTime zonedDateTime = date.toInstant().atZone(ZoneId.systemDefault());

While the OP may be working on a nix platform this answer could help non-nix platforms. I have not experienced the shebang approach work in Microsoft Windows.

Rephrased: The shebang line answers your question of "within my script" but I believe only for Unix-like platforms. Even though it is the Unix shell, outside the script, that actually interprets the shebang line to determine which version of Python interpreter to call. I am not sure, but I believe that solution does not solve the problem for Microsoft Windows platform users.

In the Microsoft Windows world, the simplify the way to run a specific Python version, without environment variables setup specifically for each specific version of Python installed, is just by prefixing the python.exe with the path you want to run it from, such as C:\Python25\python.exe mymodule.py or D:\Python27\python.exe mymodule.py

However you'd need to consider the PYTHONPATH and other PYTHON... environment variables that would point to the wrong version of Python libraries.

For example, you might run: C:\Python2.5.2\python.exe mymodule

Yet, the environment variables may point to the wrong version as such:

PYTHONPATH = D:\Python27

PYTHONLIB = D:\Python27\lib

Loads of horrible fun!

So a non-virtualenv way, in Windows, would be to use a batch file that sets up the environment and calls a specific Python executable via prefixing the python.exe with the path it resides in. This way has additional details you'll have to manage though; such as using command line arguments for either of the "start" or "cmd.exe" command to "save and replace the "console" environment" if you want the console to stick around after the application exits.

Your question leads me to believe you have several Python modules, each expecting a certain version of Python. This might be solvable "within" the script by having a launching module which uses the subprocess module. Instead of calling mymodule.py you would call a module that calls your module; perhaps launch_mymodule.py

launch_mymodule.py

import sys
import subprocess
if sys.argv[2] == '272':
  env272 = {
    'PYTHONPATH': 'blabla',
    'PYTHONLIB': 'blabla', }
  launch272 = subprocess.Popen('D:\\Python272\\python.exe mymodule.py', env=env272)

if sys.argv[1] == '252'
  env252 = {
    'PYTHONPATH': 'blabla',
    'PYTHONLIB': 'blabla', }
  launch252 = subprocess.Popen('C:\\Python252\\python.exe mymodule.py', env=env252)

I have not tested this.

Technically you could do it with a straight TCP socket. I wouldn't recommend it however. I would highly recommend you use Apache HttpClient instead. In its simplest form:

GetMethod get = new GetMethod("http://httpcomponents.apache.org");
// execute method and handle any error responses.
...
InputStream in = get.getResponseBodyAsStream();
// Process the data from the input stream.
get.releaseConnection();

and here is a more complete example.

i believe you can use

CREATE TABLE test (
  id INTEGER PRIMARY KEY AUTOINCREMENT,
  t TIMESTAMP
  DEFAULT CURRENT_TIMESTAMP
);

as of version 3.1 (source)

sequence info : max value

SELECT * FROM information_schema.sequences;

sequence info : last value

SELECT * FROM <sequence_name>

Pragma directives specify operating system or machine specific (x86 or x64 etc) compiler options. There are several options available. Details can be found in https://msdn.microsoft.com/en-us/library/d9x1s805.aspx

#pragma comment( comment-type [,"commentstring"] ) has this format.

Refer https://msdn.microsoft.com/en-us/library/7f0aews7.aspx for details about different comment-type.

#pragma comment(lib, "kernel32") #pragma comment(lib, "user32")

The above lines of code includes the library names (or path) that need to be searched by the linker. These details are included as part of the library-search record in the object file.

So, in this case kernel.lib and user32.lib are searched by the linker and included in the final executable.

I think you need to use Expr with ->set() (However THIS IS NOT SAFE and you shouldn't do it):

$qb = $this->em->createQueryBuilder();
$q = $qb->update('models\User', 'u')
        ->set('u.username', $qb->expr()->literal($username))
        ->set('u.email', $qb->expr()->literal($email))
        ->where('u.id = ?1')
        ->setParameter(1, $editId)
        ->getQuery();
$p = $q->execute();

It's much safer to make all your values parameters instead:

$qb = $this->em->createQueryBuilder();
$q = $qb->update('models\User', 'u')
        ->set('u.username', '?1')
        ->set('u.email', '?2')
        ->where('u.id = ?3')
        ->setParameter(1, $username)
        ->setParameter(2, $email)
        ->setParameter(3, $editId)
        ->getQuery();
$p = $q->execute();

I think that it's related with a route

Route::get('/article/{slug}', 'Front@slug');

associated with a particular method in my controller:

No, thats not it. The error message is coming from the route:cache command, not sure why clearing the cache calls this automatically.

The problem is a route which uses a Closure instead of a controller, which looks something like this:

//                       Thats the Closure
//                             v 
Route::get('/some/route', function() {
    return 'Hello World';
});

Since Closures can not be serialized, you can not cache your routes when you have routes which use closures.

I couldn't get any of these suggestions to work with nUnit 2.5.10 so I ended up using nUnit's Project -> Edit functionality to specify the config file to target (as others have said it needs to be in the same folder as the .nunit file itself). The positive side of this is that I can give the config file a Test.config name which makes it much clearer what it is and why it is)

SO...older thread, I know, but...

EDIT

@RoccoMusolino had a nice catch; here's an alternative:

TL;DR:

 const intArray = [...("5 6 7 69 foo 0".split(' ').filter(i => /\d/g.test(i)))]

WRONG: "5 6 note this foo".split(" ").map(Number).filter(Boolean); // [5, 6]

There is a subtle flaw in the more elegant solutions listed here, specifically @amillara and @Marcus' otherwise beautiful answers.

The problem occurs when an element of the string array isn't integer-like, perhaps in a case without validation on an input. For a contrived example...

The problem:

var effedIntArray = "5 6 7 69 foo".split(' ').map(Number); // [5, 6, 7, 69, NaN]

Since you obviously want a PURE int array, that's a problem. Honestly, I didn't catch this until I copy-pasted SO code into my script... :/

The (slightly-less-baller) fix:

var intArray = "5 6 7 69 foo".split(" ").map(Number).filter(Boolean); // [5, 6, 7, 69]

So, now even when you have crap int string, your output is a pure integer array. The others are really sexy in most cases, but I did want to offer my mostly rambly w'actually. It is still a one-liner though, to my credit...

Hope it saves someone time!

You can create you own conditional compile-time symbols (any name you like). Go to the "project Build dialog", located in the project properties box, menu option: Project->[projectname] Properties...

You can also define them "at the top of the C# code file". Like:

#define RELEASE
// or
#undef RELEASE

you can use the symbol in a #if statement:

#if RELEASE
// code ...
#elif …
// code ...
#endif

// or

#if !RELEASE
// code ...
#endif

A "table" in Excel is indeed known as a ListObject.

The "proper" way to reference a table is by getting its ListObject from its Worksheet i.e. SheetObject.ListObjects(ListObjectName).

If you want to reference a table without using the sheet, you can use a hack Application.Range(ListObjectName).ListObject.

NOTE: This hack relies on the fact that Excel always creates a named range for the table's DataBodyRange with the same name as the table. However this range name can be changed...though it's not something you'd want to do since the name will reset if you edit the table name! Also you could get a named range with no associated ListObject.

Given Excel's not-very-helpful 1004 error message when you get the name wrong, you may want to create a wrapper...

Public Function GetListObject(ByVal ListObjectName As String, Optional ParentWorksheet As Worksheet = Nothing) As Excel.ListObject
On Error Resume Next

    If (Not ParentWorksheet Is Nothing) Then
        Set GetListObject = ParentWorksheet.ListObjects(ListObjectName)
    Else
        Set GetListObject = Application.Range(ListObjectName).ListObject
    End If

On Error GoTo 0 'Or your error handler

    If (Not GetListObject Is Nothing) Then
        'Success
    ElseIf (Not ParentWorksheet Is Nothing) Then
        Call Err.Raise(1004, ThisWorkBook.Name, "ListObject '" & ListObjectName & "' not found on sheet '" & ParentWorksheet.Name & "'!")
    Else
        Call Err.Raise(1004, ThisWorkBook.Name, "ListObject '" & ListObjectName & "' not found!")
    End If

End Function

Also some good ListObject info here.

I believe the CSS-only solution text-overflow: ellipsis applies to one line only, so you won't be able to go this route:

.yourdiv {

    line-height: 1.5em; /* Sets line height to 1.5 times text size */
    height: 3em; /* Sets the div height to 2x line-height (3 times text size) */
    width: 100%; /* Use whatever width you want */
    white-space: normal; /* Wrap lines of text */
    overflow: hidden; /* Hide text that goes beyond the boundaries of the div */
    text-overflow: ellipsis; /* Ellipses (cross-browser) */
    -o-text-overflow: ellipsis; /* Ellipses (cross-browser) */
}

I have encoding problems with XMLFilter solution, so I made XMLStreamReader to ignore namespaces:

class XMLReaderWithoutNamespace extends StreamReaderDelegate {
    public XMLReaderWithoutNamespace(XMLStreamReader reader) {
      super(reader);
    }
    @Override
    public String getAttributeNamespace(int arg0) {
      return "";
    }
    @Override
    public String getNamespaceURI() {
      return "";
    }
}

InputStream is = new FileInputStream(name);
XMLStreamReader xsr = XMLInputFactory.newFactory().createXMLStreamReader(is);
XMLReaderWithoutNamespace xr = new XMLReaderWithoutNamespace(xsr);
Unmarshaller um = jc.createUnmarshaller();
Object res = um.unmarshal(xr);

Use -H or --header.

even after downloading specific required file or everything, we could face file execution error.

a file execution fail could be due to following reasons:
1. user permission/s (inheritance manhandled).
2. corrupt file.
3. file being accessed by another application at the same time.
4. file being locked by anti-malware / anti-virus software.

strangely my antivirus detected adb, avd and jndispatch.dll files as unclean files and dumped them to its vault.

i had to restore them from AVG vault. configure AVG to ignore (add folder to exception list) folder of AndroidStudio and other required folder.

if you are without antivirus and still facing this problem, remember that windows 7 and above have inbuilt 'windows defender'. see whether this fellow is doing the same thing. put your folder in antivirus 'exclusion' list as the vendor is trusted world wide.

this same answer would go to 'Error in launching AVD with AMD processor'. i don't have enough reputation to answer this question there and there.

This Post is quite old, but after hours of trying I want to share my solution … maybe it helps someone dealing with Excel and Mac and CSV and stumbles over this threat. I am generating a csv dynamically as output from a Database with Excel Users in mind. (UTF-8 with BOM)

I tried a lot of iconv´s but couldn´t get german umlauts working in Mac Excel 2004. One solution: PHPExcel. It is great but for my project a bit too much. What works for me is creating the csv file and convert this csv file to xls with this PHPsnippet: csv2xls. the result xls works with excel german umlauts (ä,ö,Ü,...).

You can use regex.findall():

import re
line = " I am having a very nice day."
count = len(re.findall(r'\w+', line))
print (count)
