In English:

• ContentType: When sending data to the server, use this content type. Default is application/x-www-form-urlencoded; charset=UTF-8, which is fine for most cases.
• Accepts: The content type sent in the request header that tells the server what kind of response it will accept in return. Depends on DataType.
• DataType: The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response. Can be text, xml, html, script, json, jsonp.

You're looking for the SyndicationFeed class, which does exactly that.

I am using the following code in one of my current projects where i download data from the internet. It is all inside my activity class.

// ---------------------------- START DownloadFileAsync // -----------------------//
class DownloadFileAsync extends AsyncTask<String, String, String> {

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        // DIALOG_DOWNLOAD_PROGRESS is defined as 0 at start of class
        showDialog(DIALOG_DOWNLOAD_PROGRESS);
    }

    @Override
    protected String doInBackground(String... urls) {
        try {
            String xmlUrl = urls[0];

            URL u = new URL(xmlUrl);
            HttpURLConnection c = (HttpURLConnection) u.openConnection();
            c.setRequestMethod("GET");
            c.setDoOutput(true);
            c.connect();

            int lengthOfFile = c.getContentLength();

            InputStream in = c.getInputStream();

            byte[] buffer = new byte[1024];
            int len1 = 0;
            long total = 0;

            while ((len1 = in.read(buffer)) > 0) {
                total += len1; // total = total + len1
                publishProgress("" + (int) ((total * 100) / lengthOfFile));
                xmlContent += buffer;
            }
        } catch (Exception e) {
            Log.d("Downloader", e.getMessage());
        }
        return null;
    }

    protected void onProgressUpdate(String... progress) {
        Log.d("ANDRO_ASYNC", progress[0]);
        mProgressDialog.setProgress(Integer.parseInt(progress[0]));
    }

    @Override
    protected void onPostExecute(String unused) {
        dismissDialog(DIALOG_DOWNLOAD_PROGRESS);
    }

}

@Override
protected Dialog onCreateDialog(int id) {
    switch (id) {
    case DIALOG_DOWNLOAD_PROGRESS:
        mProgressDialog = new ProgressDialog(this);
        mProgressDialog.setMessage("Retrieving latest announcements...");
        mProgressDialog.setIndeterminate(false);
        mProgressDialog.setMax(100);
        mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        mProgressDialog.setCancelable(true);
        mProgressDialog.show();
        return mProgressDialog;
    default:
        return null;
    }

}

The BEST way to use the AppData directory, IS to use Environment.ExpandEnvironmentVariable method.

Reasons:

• it replaces parts of your string with valid directories or whatever
• it is case-insensitive
• it is easy and uncomplicated
• it is a standard
• good for dealing with user input

Examples:

string path;
path = @"%AppData%\stuff";
path = @"%aPpdAtA%\HelloWorld";
path = @"%progRAMfiLES%\Adobe;%appdata%\FileZilla"; // collection of paths

path = Environment.ExpandEnvironmentVariables(path);
Console.WriteLine(path);

More info:

%ALLUSERSPROFILE%   C:\ProgramData
%APPDATA%   C:\Users\Username\AppData\Roaming
%COMMONPROGRAMFILES%    C:\Program Files\Common Files
%COMMONPROGRAMFILES(x86)%   C:\Program Files (x86)\Common Files
%COMSPEC%   C:\Windows\System32\cmd.exe
%HOMEDRIVE% C:
%HOMEPATH%  C:\Users\Username
%LOCALAPPDATA%  C:\Users\Username\AppData\Local
%PROGRAMDATA%   C:\ProgramData
%PROGRAMFILES%  C:\Program Files
%PROGRAMFILES(X86)% C:\Program Files (x86) (only in 64-bit version)
%PUBLIC%    C:\Users\Public

Do you have this namespace setup? You will have to ensure that this namespace matches the message namespace. If you can update your question with the xml input and possibly your data object that would be helpful.

[DataContract(Namespace = "http://CompanyName.com.au/ProjectName")]
public class CustomFields
{
  // ...
}

No, there is no chance to do that. You just learned how important a backup can be.

In my case (I'm using VS 2017) works fine the following simple code:

#include "pch.h"
#include <iostream>
#include <stdlib.h>
#include <time.h>

int main()
{
    srand(time(NULL));

    for (int i = 1000; i > 0; i--) //try it thousand times
    {
        int randnum = (double)rand() / ((double)RAND_MAX + 1);
        std::cout << " rnum: " << rand()%2 ;
    }
} 

Here is how you can read the entire file contents, and if done successfully, start a webserver which displays the JPG image in response to every request:

var http = require('http')
var fs = require('fs')

fs.readFile('image.jpg', function(err, data) {
  if (err) throw err // Fail if the file can't be read.
  http.createServer(function(req, res) {
    res.writeHead(200, {'Content-Type': 'image/jpeg'})
    res.end(data) // Send the file data to the browser.
  }).listen(8124)
  console.log('Server running at http://localhost:8124/')
})

Note that the server is launched by the "readFile" callback function and the response header has Content-Type: image/jpeg.

[Edit] You could even embed the image in an HTML page directly by using an <img> with a data URI source. For example:

  res.writeHead(200, {'Content-Type': 'text/html'});
  res.write('<html><body><img src="data:image/jpeg;base64,')
  res.write(Buffer.from(data).toString('base64'));
  res.end('"/></body></html>');

Fixed by adding crossorigin to the script tag.

From: https://code.jquery.com/

<script
  src="https://code.jquery.com/jquery-3.4.1.min.js"
  integrity="sha256-CSXorXvZcTkaix6Yvo6HppcZGetbYMGWSFlBw8HfCJo="
  crossorigin="anonymous"></script>

The integrity and crossorigin attributes are used for Subresource Integrity (SRI) checking. This allows browsers to ensure that resources hosted on third-party servers have not been tampered with. Use of SRI is recommended as a best-practice, whenever libraries are loaded from a third-party source. Read more at srihash.org

The answers in question you linked-to are all about configuring git so that you can enter very short git push commands and have them do whatever you want. Which is great, if you know what you want and how to spell that in Git-Ese, but you're new to git! :-)

In your case, Petr Mensik's answer is the (well, "a") right one. Here's why:

The command git push remote roots around in your .git/config file to find the named "remote" (e.g., origin). The config file lists:

• where (URL-wise) that remote "lives" (e.g., ssh://hostname/path)
• where pushes go, if different
• what gets pushed, if you didn't say what branch(es) to push
• what gets fetched when you run git fetch remote

When you first cloned the repo—whenever that was—git set up default values for some of these. The URL is whatever you cloned from and the rest, if set or unset, are all "reasonable" defaults ... or, hmm, are they?

The issue with these is that people have changed their minds, over time, as to what is "reasonable". So now (depending on your version of git and whether you've configured things in detail), git may print a lot of warnings about defaults changing in the future. Adding the name of the "branch to push"—amd_qlp_tester—(1) shuts it up, and (2) pushes just that one branch.

If you want to push more conveniently, you could do that with:

git push origin

or even:

git push

but whether that does what you want, depends on whether you agree with "early git authors" that the original defaults are reasonable, or "later git authors" that the original defaults aren't reasonable. So, when you want to do all the configuration stuff (eventually), see the question (and answers) you linked-to.

As for the name origin/amd_qlp_tester in the first place: that's actually a local entity (a name kept inside your repo), even though it's called a "remote branch". It's git's best guess at "where amd_qlp_tester is over there". Git updates it when it can.

Have you tried to change in Tortoise Settings the status cache to 'Default'? I had this problem with the overlay icon on folders because I had this option in 'Shell'. The option is in Settings -> Icons overlay.

Maybe this could help you http://tortoisesvn.net/node/97

You need something like a regular expression.

You have to be in Extended mode

If you want all the lines to end up on a single line use \r\n. If you want to simply remove empty lines, use \n\r as @Link originally suggested.

Replace either expression with nothing.

1. Go into Finder.
2. On the sidebar, click applications.
3. Find Xcode in Applications.
4. Right click Xcode by whatever settings you have (usually two finger click [not tap]).
5. Click "Show Package Contents."
6. Go into the Contents folder.
7. Search simulator.
8. Wait 30 secs for it to load.
9. Scroll down and find iOS Simulator.
10. You may drag this onto the dock for easier access.

I hope this helps!

If you close the main Activity using Activity.finish(), I think it will close all the activities. MAybe you can override the default function, and implement it in a static way, I'm not sure

I believe you are now able to use Window.getComputedStyle()

Documentation MDN

var style = window.getComputedStyle(element[, pseudoElt]);

Example to get width of an element:

window.getComputedStyle(document.querySelector('#mainbar')).width

In my case .NET CRL Version in Application pool prppertires was set to No managed code (do not know why). Setting it to .NET CRL Version v4.0.30319 solved the problem.

This method uses regexp, it should work:

awk '$2 ~ /findtext/ {print $3}' <infile>

By changing one level in the "logging.config.dictConfig" you'll be able to take the whole logging level to a new level.

logging.config.dictConfig({
'version': 1,
'disable_existing_loggers': False,
'formatters': {
    'console': {
        'format': '%(name)-12s %(levelname)-8s %(message)s'
    },
    'file': {
        'format': '%(asctime)s %(name)-12s %(levelname)-8s %(message)s'
    }
},
'handlers': {
    'console': {
        'class': 'logging.StreamHandler',
        'formatter': 'console'
    },
#CHANGE below level from DEBUG to THE_LEVEL_YOU_WANT_TO_SWITCH_FOR
#if we jump from DEBUG to INFO
# we won't be able to see the DEBUG logs in our logging.log file
    'file': {
        'level': 'DEBUG',
        'class': 'logging.FileHandler',
        'formatter': 'file',
        'filename': 'logging.log'
    },
},
'loggers': {
    '': {
        'level': 'DEBUG',
        'handlers': ['console', 'file'],
        'propagate': False,
    },
}

})

1. you can set your classpath in the in the environment variabl CLASSPATH. in linux, you can add like CLASSPATH=.:/full/path/to/the/Jars, for example ..........src/external and just run in side ......src/Report/

Javac Reporter.java

java Reporter

Similarily, you can set it in windows environment variables. for example, in Win7

Right click Start-->Computer then Properties-->Advanced System Setting --> Advanced -->Environment Variables in the user variables, click classPath, and Edit and add the full path of jars at the end. voila

Here are 3 functions I use frequently to get the text width, height and adjust the size to the container's width.

• getTextWidth() will return you the actual width of the text contained in the initiator.
• getTextHeight(width) will return the actual height of the wrapped text contained in the initiator with a certain specified width.
• autoTextSize(minSize, maxSize, truncate) will size the text within the container so it fits, considering a minimum and maximum size.
• autoTruncateText() will only show the characters the user can actually see and end the text with '...'.

(function ($) {
  $.fn.getTextWidth = function() {
    var spanText = $("BODY #spanCalculateTextWidth");

    if (spanText.size() <= 0) {
      spanText = $("<span id='spanCalculateTextWidth' style='filter: alpha(0);'></span>");
      spanText.appendTo("BODY");
    }

    var valu = this.val();
    if (!valu) valu = this.text();

    spanText.text(valu);

    spanText.css({
      "fontSize": this.css('fontSize'),

      "position": "absolute",
      "top": 0,
      "opacity": 0,
      "left": -2000
    });

    return spanText.outerWidth() + parseInt(this.css('paddingLeft')) + 'px';
  };

  $.fn.getTextHeight = function(width) {
    var spanText = $("BODY #spanCalculateTextHeight");

    if (spanText.size() <= 0) {
      spanText = $("<span id='spanCalculateTextHeight'></span>");
      spanText.appendTo("BODY");
    }

    var valu = this.val();

    var lastChar = _text[_text.length - 1];

The difference between page and window with respect to WPF: Page vs Window in WPF?

Found the chrome Options class in the Selenium source code.

Usage to create a Chrome driver instance:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument("--disable-extensions")
driver = webdriver.Chrome(chrome_options=chrome_options)

Here is what I did using cairosvg:

from cairosvg import svg2png

svg_code = """
    <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="#000" stroke-width="2" stroke-linecap="round" stroke-linejoin="round">
        <circle cx="12" cy="12" r="10"/>
        <line x1="12" y1="8" x2="12" y2="12"/>

    </svg>
"""

svg2png(bytestring=svg_code,write_to='output.png')

And it works like a charm!

If all you want to do is to switch from inline plots to interactive and back (so that you can pan/zoom), it is better to use %matplotlib magic.

#interactive plotting in separate window
%matplotlib qt 

and back to html

#normal charts inside notebooks
%matplotlib inline 

%pylab magic imports a bunch of other things and may even result in a conflict. It does "from pylab import *".

You also can use new notebook backend (added in matplotlib 1.4):

#interactive charts inside notebooks, matplotlib 1.4+
%matplotlib notebook 

If you want to have more interactivity in your charts, you can look at mpld3 and bokeh. mpld3 is great, if you don't have ton's of data points (e.g. <5k+) and you want to use normal matplotlib syntax, but more interactivity, compared to %matplotlib notebook . Bokeh can handle lots of data, but you need to learn it's syntax as it is a separate library.

Also you can check out pivottablejs (pip install pivottablejs)

from pivottablejs import pivot_ui
pivot_ui(df)

However cool interactive data exploration is, it can totally mess with reproducibility. It has happened to me, so I try to use it only at the very early stage and switch to pure inline matplotlib/seaborn, once I got the feel for the data.

In my case i just missed the slash "/" after get_template_directory_uri() so resulted / generated path was wrong:

My Wrong code :

wp_enqueue_script( 'retina-js', get_template_directory_uri().'js/retina.min.js' ); 

My Corrected Code :

wp_enqueue_script( 'retina-js', get_template_directory_uri().'/js/retina.min.js' );

As pointed out already, most standard implementations of List are serializable. However you have to ensure that the objects referenced/contained within the list are also serializable.

It's better to create a new factor variable using cut(). I've added a few options using ggplot2 also.

df <- data.frame(
  X1=seq(0, 5, by=0.001),
  X2=rnorm(df$X1, mean = 3.5, sd = 1.5)
)

# Create new variable for plotting
df$Colour <- cut(df$X2, breaks = c(-Inf, 1, 3, +Inf), 
                 labels = c("low", "medium", "high"), 
                 right = FALSE)

### Base Graphics

plot(df$X1, df$X2, 
     col = df$Colour, ylim = c(0, 10), xlab = "POS", 
     ylab = "CS", main = "Plot Title", pch = 21)

plot(df$X1,df$X2, 
     col = df$Colour, ylim = c(0, 10), xlab = "POS", 
     ylab = "CS", main = "Plot Title", pch = 19, cex = 0.5)

# Using `with()` 

with(df, 
     plot(X1, X2, xlab="POS", ylab="CS", col = Colour, pch=21, cex=1.4)
     )

# Using ggplot2
library(ggplot2)

# qplot()
qplot(df$X1, df$X2, colour = df$Colour)

# ggplot()
p <- ggplot(df, aes(X1, X2, colour = Colour)) 
p <- p + geom_point() + xlab("POS") + ylab("CS")
p

p + facet_grid(Colour~., scales = "free")

Putting the condition in the join seems "semantically wrong" to me, as that's not what JOINs are "for". But that's very qualitative.

Additional problem: if you decide to switch from an inner join to, say, a right join, having the condition be inside the JOIN could lead to unexpected results.

There is an official documentation page about this as well.

Examples from that page include:

mongo server:27017/dbname --quiet my_commands.js
mongo test --eval "printjson(db.getCollectionNames())"

You should use std::iota algorithm (defined in <numeric>):

  std::vector<int> ivec(100);
  std::iota(ivec.begin(), ivec.end(), 0); // ivec will become: [0..99]

Because std::fill just assigns the given fixed value to the elements in the given range [n1,n2). And std::iota fills the given range [n1, n2) with sequentially increasing values, starting with the initial value and then using ++value.You can also use std::generate as an alternative.

Don't forget that std::iota is C++11 STL algorithm. But a lot of modern compilers support it e.g. GCC, Clang and VS2012 : http://msdn.microsoft.com/en-us/library/vstudio/jj651033.aspx

P.S. This function is named after the integer function ? from the programming language APL, and signifies a Greek letter iota. I speculate that originally in APL this odd name was chosen because it resembles an “integer” (even though in mathematics iota is widely used to denote the imaginary part of a complex number).

 $<input name="currency">

It tells the compiler that you're in a Single Thread Apartment model. This is an evil COM thing, it's usually used for Windows Forms (GUI's) as that uses Win32 for its drawing, which is implemented as STA. If you are using something that's STA model from multiple threads then you get corrupted objects.

This is why you have to invoke onto the Gui from another thread (if you've done any forms coding).

Basically don't worry about it, just accept that Windows GUI threads must be marked as STA otherwise weird stuff happens.

One can also use the following syntax in typescript. Note the backtick " ` "

window.location.hash = `${page_number}`

Since other solutions are old and either poorly-working or not working at all, I've modified NestedScrollView, which is stable, modern and it has all you expect from a scroll view. Except for horizontal scrolling.

Here's the repo: https://github.com/ultimate-deej/TwoWayNestedScrollView

I've made no changes, no "improvements" to the original NestedScrollView expect for what was absolutely necessary. The code is based on androidx.core:core:1.3.0, which is the latest stable version at the time of writing.

All of the following works:

• Lift on scroll (since it's basically a NestedScrollView)
• Edge effects in both dimensions
• Fill viewport in both dimensions

Quoting the doc:

Some attributes do not apply to all data types. AUTO_INCREMENT applies only to integer and floating-point types. DEFAULT does not apply to the BLOB or TEXT types.

In your case, you're trying to apply AUTO_INCREMENT modifier to char column. To solve this, either drop AUTO_INCREMENT altogether (that means you'll have to generate a unique id on the application level) or just change topic_id type to the relevant integer one.

As a sidenote, it makes little sense using char(36) to store the posts count, so that column's type probably has to be changed as well. It looks like you're going this way to prevent integer overflow - but if you're dealing with more than 18446744073709551615 posts (the biggest number that can be stored in BIGINT UNSIGNED column) in a single topic, you have far bigger problem on your side probably. )

Actually one can always create an ordinary list of numpy arrays and convert it later.

In [1]: import numpy as np

In [2]: a = np.array([[1,2],[3,4]])

In [3]: b = np.array([[1,2],[3,4]])

In [4]: l = [a]

In [5]: l.append(b)

In [6]: l = np.array(l)

In [7]: l.shape
Out[7]: (2, 2, 2)

In [8]: l
Out[8]: 
array([[[1, 2],
        [3, 4]],

       [[1, 2],
        [3, 4]]])

From APUE, Section 5.14 :

char    good_template[] = "/tmp/dirXXXXXX"; /* right way */
char    *bad_template = "/tmp/dirXXXXXX";   /* wrong way*/

... For the first template, the name is allocated on the stack, because we use an array variable. For the second name, however, we use a pointer. In this case, only the memory for the pointer itself resides on the stack; the compiler arranges for the string to be stored in the read-only segment of the executable. When the mkstemp function tries to modify the string, a segmentation fault occurs.

The quoted text matches @Ciro Santilli 's explanation.

I'd guess that Remove and Substring would tie for first place, since they both slurp up a fixed-size portion of the string, whereas TrimStart does a scan from the left with a test on each character and then has to perform exactly the same work as the other two methods. Seriously, though, this is splitting hairs.

You need to add a vertical-align property to your two child div's.

If .small is always shorter, you need only apply the property to .small. However, if either could be tallest then you should apply the property to both .small and .big.

.container{ 
    border: 1px black solid;
    width: 320px;
    height: 120px;    
}

.small{
    display: inline-block;
    width: 40%;
    height: 30%;
    border: 1px black solid;
    background: aliceblue; 
    vertical-align: top;   
}

Vertical align affects inline or table-cell box's, and there are a large nubmer of different values for this property. Please see https://developer.mozilla.org/en-US/docs/Web/CSS/vertical-align for more details.

Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors at your server side.

You can fetch request using mode: 'cors'. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.

So in both condition you need to configure cors in your server or you need to use custom proxy server.

In case, if you want to do some job on the selection of one of the radio buttons (without having any additional OK button or something), your code is fine, updated little.

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        RadioGroup rg = (RadioGroup) findViewById(R.id.radioGroup1);

        rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() 
        {
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                switch(checkedId){
                    case R.id.radio0:
                        // do operations specific to this selection
                        break;
                    case R.id.radio1:
                        // do operations specific to this selection
                        break;
                    case R.id.radio2:
                        // do operations specific to this selection
                        break;
                }   
            }
        });
    }
}

We can easily find xor of two variables by the using:

def xor(a,b):
    return a !=b

Example:

xor(True,False) >>> True

Like others have mentioned, the Google Places Autocomplete API is missing some important functions. Case in point, Google will not validate that the street number is real, and they also will not put it into a standardized format. So, it is the user's responsibility to enter that portion of the address correctly.

Google also won't predict PO Boxes or apartment numbers. So, if you are using their API for shipping, address cleansing or data governance, you may want one that will validate the building number, autocomplete the unit number and standardize the information.

Full Disclosure, I work for SmartyStreets

textarea:hover,
input:hover,
textarea:active,
input:active,
textarea:focus,
input:focus
{
    outline: 0px !important;
    border: none!important;
}

*use border:none; instead of outline because the focus line is a border not a outline.

Django 1.10+

Use an attribute, not a method:

if request.user.is_authenticated: # <-  no parentheses any more!
    # do something if the user is authenticated

The use of the method of the same name is deprecated in Django 2.0, and is no longer mentioned in the Django documentation.

return HttpResponse(json.dumps({
    "is_authenticated": request.user.is_authenticated()
}), content_type='application/json') 

that after updated to the property request.user.is_authenticated was throwing the exception TypeError: Object of type 'CallableBool' is not JSON serializable. The solution was to use JsonResponse, which could handle the CallableBool object properly when serializing:

return JsonResponse({
    "is_authenticated": request.user.is_authenticated
})

You have to link against libdl, add

-ldl

to your linker options

For doing so you just have to use the revert command, specifying the range of commits you want to get reverted.

Taking into account your example, you'd have to do this (assuming you're on branch 'master'):

git revert master~3..master

or git revert B...D or git revert D C B

This will create a new commit in your local with the inverse commit of B, C and D (meaning that it will undo changes introduced by these commits):

A <- B <- C <- D <- BCD' <- HEAD

This PoC constantly reads the output from a process and can be accessed when needed. Only the last result is kept, all other output is discarded, hence prevents the PIPE from growing out of memory:

import subprocess
import time
import threading
import Queue


class FlushPipe(object):
    def __init__(self):
        self.command = ['python', './print_date.py']
        self.process = None
        self.process_output = Queue.LifoQueue(0)
        self.capture_output = threading.Thread(target=self.output_reader)

    def output_reader(self):
        for line in iter(self.process.stdout.readline, b''):
            self.process_output.put_nowait(line)

    def start_process(self):
        self.process = subprocess.Popen(self.command,
                                        stdout=subprocess.PIPE)
        self.capture_output.start()

    def get_output_for_processing(self):
        line = self.process_output.get()
        print ">>>" + line


if __name__ == "__main__":
    flush_pipe = FlushPipe()
    flush_pipe.start_process()

    now = time.time()
    while time.time() - now < 10:
        flush_pipe.get_output_for_processing()
        time.sleep(2.5)

    flush_pipe.capture_output.join(timeout=0.001)
    flush_pipe.process.kill()

print_date.py

import time

if __name__ == "__main__":
    while True:
        print str(time.time())
        time.sleep(0.01)

output: You can clearly see that there is only output from ~2.5s interval nothing in between.

The OR operator needs a much more complex evaluation process than the IN construct because it allows many conditions, not only equals like IN.

Here is a like of what you can use with OR but that are not compatible with IN: greater. greater or equal, less, less or equal, LIKE and some more like the oracle REGEXP_LIKE. In addition consider that the conditions may not always compare the same value.

For the query optimizer it's easier to to manage the IN operator because is only a construct that defines the OR operator on multiple conditions with = operator on the same value. If you use the OR operator the optimizer may not consider that you're always using the = operator on the same value and, if it doesn't perform a deeper and very much more complex elaboration, it could probably exclude that there may be only = operators for the same values on all the involved conditions, with a consequent preclusion of optimized search methods like the already mentioned binary search.

[EDIT] Probably an optimizer may not implement optimized IN evaluation process, but this doesn't exclude that one time it could happen(with a database version upgrade). So if you use the OR operator that optimized elaboration will not be used in your case.

Join the same table back to itself. Use an inner join so that rows that don't match are discarded. In the joined set, there will be rows that have a matching ARIDNR in another row in the table with a different LIEFNR. Allow those ARIDNR to appear in the final set.

SELECT * FROM YourTable WHERE ARIDNR IN (
    SELECT a.ARIDNR FROM YourTable a
    JOIN YourTable b on b.ARIDNR = a.ARIDNR AND b.LIEFNR <> a.LIEFNR
)

Tested Code:

$("input").css("background","red");

Complete:

$('input:text').focus(function () {
    $(this).css({ 'background': 'Black' });
});

$('input:text').blur(function () {
    $(this).css({ 'background': 'red' });
});

With Angular CLI 6 you need to use builders as ng eject is deprecated and will soon be removed in 8.0. That's what it says when I try to do an ng eject

You can use angular-builders package (https://github.com/meltedspark/angular-builders) to provide your custom webpack config.

I have tried to summarize all in a single blog post on my blog - How to customize build configuration with custom webpack config in Angular CLI 6

but essentially you add following dependencies -

  "devDependencies": {
    "@angular-builders/custom-webpack": "^7.0.0",
    "@angular-builders/dev-server": "^7.0.0",
    "@angular-devkit/build-angular": "~0.11.0",

In angular.json make following changes -

  "architect": {
    "build": {
      "builder": "@angular-builders/custom-webpack:browser",
      "options": {
        "customWebpackConfig": {"path": "./custom-webpack.config.js"},

Notice change in builder and new option customWebpackConfig. Also change

    "serve": {
      "builder": "@angular-builders/dev-server:generic",

Notice the change in builder again for serve target. Post these changes you can create a file called custom-webpack.config.js in your same root directory and add your webpack config there.

However, unlike ng eject configuration provided here will be merged with default config so just add stuff you want to edit/add.

A more explicit option is to project collection to an IEnumerable of KeyValuePair and then convert it to a Dictionary.

Dictionary<int, string> dictionary = objects
    .Select(x=> new KeyValuePair<int, string>(x.Id, x.Name))
    .ToDictionary(x=>x.Key, x=>x.Value);

If you install the third party package:

npm i cordova-check-plugins

You can then run a simple command of

cordova-check-plugins --update=auto --force

Keep in mind forcing anything always comes with potential risks of breaking changes.

As other answers have stated, the connecting NPM packages that manage these plugins also require a consequent update when updating the plugins, so now you can check them with:

npm outdated

And then sweeping update them with

npm update

Now tentatively serve your app again and check all of the things that have potentially gone awry from breaking changes. The joy of software development! :)

Goto Windows Features on or Off . Enable All Features under Application Development Features and Refresh the IIS. Its Working

Just my two cents to this very old question. I would highly recommend taking a look at ElasticSearch.

Elasticsearch is a search server based on Lucene. It provides a distributed, multitenant-capable full-text search engine with a RESTful web interface and schema-free JSON documents. Elasticsearch is developed in Java and is released as open source under the terms of the Apache License.

The advantages over other FTS (full text search) Engines are:

• RESTful interface
• Better scalability
• Large community
• Built by Lucene developers
• Extensive documentation
• There are many open source libraries available (including Django)

We are using this search engine at our project and very happy with it.

Which version of Bootstrap are you using? I was perplexed that I could get @Chad's solution to work in jsfiddle, but not locally. So, I checked the version of Bootstrap used by jsfiddle, and it's using a 3.0.0-rc1 release, while the default download on getbootstrap.com is version 2.3.2.

In 2.3.2 the collapse class wasn't getting replaced by the in class. The in class was simply getting appended when the button was clicked. In version 3.0.0-rc1, the collapse class correctly is removed, and the <tr> collapses.

Use @Chad's solution for the html, and try using these links for referencing Bootstrap:

<link href="http://netdna.bootstrapcdn.com/bootstrap/3.0.0-rc1/css/bootstrap.min.css" rel="stylesheet">
<script src="http://netdna.bootstrapcdn.com/bootstrap/3.0.0-rc1/js/bootstrap.min.js"></script>

If you use Spring boot, consider to remove server.tomcat.additional-tld-skip-patterns=*.jar from Application.properties if there is any

 var text = File.ReadAllText(file, Encoding.GetEncoding(codePage));

List of codepages : http://msdn.microsoft.com/en-us/library/windows/desktop/dd317756(v=vs.85).aspx

If you do not like double quotes like me, this will work for you with single quotes:

$value = Input::get('q');
$books = Book::where('name', 'LIKE', '%' . $value . '%')->limit(25)->get();

return view('pages/search/index', compact('books'));

Updated: C++11 brought the types from TR1 officially into the standard:

• long long int
• unsigned long long int

And the "sized" types from <cstdint>

• int8_t
• int16_t
• int32_t
• int64_t
• (and the unsigned counterparts).

Plus you get:

• int_least8_t
• int_least16_t
• int_least32_t
• int_least64_t
• Plus the unsigned counterparts.

These types represent the smallest integer types with at least the specified number of bits. Likewise there are the "fastest" integer types with at least the specified number of bits:

• int_fast8_t
• int_fast16_t
• int_fast32_t
• int_fast64_t
• Plus the unsigned versions.

What "fast" means, if anything, is up to the implementation. It need not be the fastest for all purposes either.

Too late for the question but will post my answer anyway for anyone still needs it. I found an easier way to implement this, without using fragment id or fragment tag, since that's what I was seeking for.

First, I declared my Fragment in my ParentActivity class:

MyFragment myFragment;

Initialized my viewPager as usual, with the fragment I already added in the class above. Then, created a public method called scrollToTop in myFragment that does what I want to do from ParentActivity, let's say scroll my recyclerview to the top.

public void scrollToTop(){
    mMainRecyclerView.smoothScrollToPosition(0);
}

Now, in ParentActivity I called the method as below:

try{
   myFragment.scrollToTop();
}catch (Exception e){
   e.printStackTrace();
}

If you need one single regex, try:

(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*\W)

A short explanation:

(?=.*[a-z])        // use positive look ahead to see if at least one lower case letter exists
(?=.*[A-Z])        // use positive look ahead to see if at least one upper case letter exists
(?=.*\d)           // use positive look ahead to see if at least one digit exists
(?=.*\W])        // use positive look ahead to see if at least one non-word character exists

And I agree with SilentGhost, \W might be a bit broad. I'd replace it with a character set like this: [-+_!@#$%^&*.,?] (feel free to add more of course!)

An abstract class can have a constructor BUT you can not create an object of abstract class so how do you use that constructor?

Thing is when you inherit that abstract class in your subclass you can pass values to its(abstract's) constructor through super(value) method in your subclass and no you don't inherit a constructor.

so using super you can pass values in a constructor of the abstract class and as far as I remember it has to be the first statement in your method or constructor.

Try to use single quotes (') to avoid shell escaping of your string. Remember that the expression needs to match the whole path, i.e. needs to look like:

 find . -regex '\./[a-f0-9-]*.jpg'

Apart from that, it seems that my find (GNU 4.4.2) only knows basic regular expressions, especially not the {36} syntax. I think you'll have to make do without it.

Static classes can be useful in certain situations, but there is a potential to abuse and/or overuse them, like most language features.

As Dylan Smith already mentioned, the most obvious case for using a static class is if you have a class with only static methods. There is no point in allowing developers to instantiate such a class.

The caveat is that an overabundance of static methods may itself indicate a flaw in your design strategy. I find that when you are creating a static function, its a good to ask yourself -- would it be better suited as either a) an instance method, or b) an extension method to an interface. The idea here is that object behaviors are usually associated with object state, meaning the behavior should belong to the object. By using a static function you are implying that the behavior shouldn't belong to any particular object.

Polymorphic and interface driven design are hindered by overusing static functions -- they cannot be overriden in derived classes nor can they be attached to an interface. Its usually better to have your 'helper' functions tied to an interface via an extension method such that all instances of the interface have access to that shared 'helper' functionality.

One situation where static functions are definitely useful, in my opinion, is in creating a .Create() or .New() method to implement logic for object creation, for instance when you want to proxy the object being created,

public class Foo
{
    public static Foo New(string fooString)
    {
        ProxyGenerator generator = new ProxyGenerator();

        return (Foo)generator.CreateClassProxy
             (typeof(Foo), new object[] { fooString }, new Interceptor()); 
    }

This can be used with a proxying framework (like Castle Dynamic Proxy) where you want to intercept / inject functionality into an object, based on say, certain attributes assigned to its methods. The overall idea is that you need a special constructor because technically you are creating a copy of the original instance with special added functionality.

Weston Ruther built a similar thing using the WebKit proposal for css transitions:

http://weston.ruter.net/projects/jquery-css-transitions/

This implementation might be useful for you.

I just encountered this.

1) Find the cygwin setup.exe file from http://cygwin.com/ and run it.
2) Click/enter preferences until you reach the "Select Packages" window. (See image)
3) Click (+) for Net
4) Click the entry for curl. (Make sure you select the checkbox for the Binary)
5) Install.
6) Open a cygwin window and type curl.exe (should be available now).

I've had the same thing happen when I had a number of MSBuild processes running in the background which had effectively crashed (they had references to old versions of code). I closed VS and killed all the MSBuild processes in process explorer and then recompiled.

RewriteEngine, DirectoryIndex in .htaccess file of CodeIgniter apps

I just changed the .htaccess file contents and as shown in the following links answer. And tried refreshing the page (which didn't work, and couldn't find the request to my controller) it worked.

Then just because of my doubt I undone the changes I did to my .htaccess inside my public_html folder back to original .htaccess content. So it's now as follows (which is originally it was):

DirectoryIndex index.php
RewriteEngine on
RewriteCond $1 !^(index\.php|images|css|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php?/$1 [L,QSA]

And now also it works.

Hint: Seems like before the Rewrite Rules haven't been clearly setup within the Server context.

My file structure is as follows:

/
|- gheapp
|    |- application
|    L- system
|
|- public_html
|    |- .htaccess
|    L- index.php

And in the index.php I have set up the following paths to the system and the application:

$system_path = '../gheapp/system';
$application_folder = '../gheapp/application';

Note: by doing so, our application source code becomes hidden to the public at first.

Please, if you guys find anything wrong with my answer, comment and re-correct me!
Hope beginners would find this answer helpful.

Thanks!

My issue was that I was on a machine with node version 0.12.2, but that had an old 1.x.x version of npm. Be sure to update your version of npm: sudo npm install -g npm Once that is done, remove any existing node-sass and reinstall it via npm.

This code needs to be put inside Run SQL query/queries on database

SQL QUERY WINDOW

ALTER TABLE `table_name` CHANGE `column_name` `column_name`   VARCHAR(128) CHARACTER SET utf8 COLLATE utf8_unicode_ci NULL DEFAULT NULL;

Please replace table_name and column_name with appropriate name.

For small algorithms you can use the module timeit from python documentation:

def test():
    "Stupid test function"
    L = []
    for i in range(100):
        L.append(i)

if __name__=='__main__':
    from timeit import Timer
    t = Timer("test()", "from __main__ import test")
    print t.timeit()

Less accurately but still valid you can use module time like this:

from time import time
t0 = time()
call_mifuntion_vers_1()
t1 = time()
call_mifunction_vers_2()
t2 = time()

print 'function vers1 takes %f' %(t1-t0)
print 'function vers2 takes %f' %(t2-t1)

document.getElementById("your checkbox id").disabled=true;

You can access columns by index, by name and some other ways:

dtResult.Rows(i)("columnName") = strVerse

You should probably make sure your DataTable has some columns first...

This is the only install that resolved the issue for me.

This happened to me just today, so I am writing what came out as a lifesaver for me. My answer is very similar to @Amber 's answer.

First, I did a git reflog and searched for that particular commit's hash, then just copied that hash and did a git cherry-pick <hash> from that branch. This brought all the change from that lost commit to my current branch, and restored my faith on GIT.

UPDATE: Using HTTPS is now exempt from the ERN as of late September, 2016

https://stackoverflow.com/a/40919650/4976373

Unfortunately, I believe that your app "contains encryption" in terms of US BIS even if you just use HTTPS (if your app is not an exception included in question 2).

Quote from FAQ on iTunes Connect:

"How do I know if I can follow the Exporter Registration and Reporting (ERN) process?

If your app uses, accesses, implements or incorporates industry standard encryption algorithms for purposes other than those listed as exemptions under question 2, you need to submit for an ERN authorization. Examples of standard encryption are: AES, SSL, https. This authorization requires that you submit an annual report to two U.S. Government agencies with information about your app every January. "

"2nd Question: Does your product qualify for any exemptions provided under category 5 part 2?

There are several exemptions available in US export regulations under Category 5 Part 2 (Information Security & Encryption regulations) for applications and software that use, access, implement or incorporate encryption.

All liabilities associated with misinterpretation of the export regulations or claiming exemption inaccurately are borne by owners and developers of the apps.

You can answer “YES” to the question if you meet any of the following criteria:

(i) if you determine that your app is not classified under Category 5, Part 2 of the EAR based on the guidance provided by BIS at encryption question. The Statement of Understanding for medical equipment in Supplement No. 3 to Part 774 of the EAR can be accessed at Electronic Code of Federal Regulations site. Please visit the Question #15 in the FAQ section of the encryption page for sample items BIS has listed that can claim Note 4 exemptions.

(ii) your app uses, accesses, implements or incorporates encryption for authentication only

(iii) your app uses, accesses, implements or incorporates encryption with key lengths not exceeding 56 bits symmetric, 512 bits asymmetric and/or 112 bit elliptic curve

(iv) your app is a mass market product with key lengths not exceeding 64 bits symmetric, or if no symmetric algorithms, not exceeding 768 bits asymmetric and/or 128 bits elliptic curve.

Please review Note 3 in Category 5 Part 2 to understand the criteria for mass market definition.

(v) your app is specially designed and limited for banking use or ‘money transactions.’ The term ‘money transactions’ includes the collection and settlement of fares or credit functions.

(vi) the source code of your app is “publicly available”, your app distributed at free of cost to general public, and you have met the notification requirements provided under 740.13.(e).

Please visit encryption web page in case you need further help in determining if your app qualifies for any exemptions.

If you believe that your app qualifies for an exemption, please answer “YES” to the question."

Simple Explanation by analogy

Imagine you are in a bank, trying to get some money out of your account. But it's dark; the bank is pitch black: there's no light and you can't see your hand in front of your face. You are surrounded by another 20 people. They all look the same. And everybody has the same voice. And everyone is a potential bad guy. In other words, HTTP is stateless.

This bank is a funny type of bank - for the sake of argument here's how things work:

1. you wait in line (or on-line) and you talk to the teller: you make a request to withdraw money, and then
2. you have to wait briefly on the sofa, and 20 minutes later
3. you have to go and actually collect your money from the teller.

But how will the teller tell you apart from everyone else?

The teller can't see or readily recognise you, remember, because the lights are all out. What if your teller gives your $10,000 withdrawal to someone else - the wrong person?! It's absolutely vital that the teller can recognise you as the one who made the withdrawal, so that you can get the money (or resource) that you asked for.

Solution:

When you first appear to the teller, he or she tells you something in secret:

"When ever you are talking to me," says the teller, "you should first identify yourlself as GNASHEU329 - that way I know it's you".

Nobody else knows the secret passcode.

Example of How I Withdrew Cash:

So I decide to go to and chill out for 20 minutes and then later i go to the teller and say "I'd like to collect my withdrawal"

The teller asks me: "who are you??!"

"It's me, Mr George Banks!"

"Prove it!"

And then I tell them my passcode: GNASHEU329

"Certainly Mr Banks!"

That basically is how a session works. It allows one to be uniquely identified in a sea of millions of people. You need to identify yourself every time you deal with the teller.

If you got any questions or are unclear - please post comment and i will try to clear it up for you. The following is not strictly speaking, completely accurate in its terminology, but I hope it's helpful to you in understanding concepts.

Explanation via Pictures:

Not much documentation on PowerShell loops.

Documentation on loops in PowerShell is plentiful, and you might want to check out the following help topics: about_For, about_ForEach, about_Do, about_While.

foreach($line in Get-Content .\file.txt) {
    if($line -match $regex){
        # Work here
    }
}

Another idiomatic PowerShell solution to your problem is to pipe the lines of the text file to the ForEach-Object cmdlet:

Get-Content .\file.txt | ForEach-Object {
    if($_ -match $regex){
        # Work here
    }
}

Instead of regex matching inside the loop, you could pipe the lines through Where-Object to filter just those you're interested in:

Get-Content .\file.txt | Where-Object {$_ -match $regex} | ForEach-Object {
    # Work here
}

Not in stock Windows but it is provided by Services for Unix and there are several simple batch scripts floating around that accomplish the same thing such this this one.

Example without any XML

Put your image image_name.jpg into res/drawable/image_name.jpg and use:

import android.app.Activity;
import android.os.Bundle;
import android.widget.ImageView;

public class Main extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        final ImageView imageView = new ImageView(this);
        imageView.setImageResource(R.drawable.image_name);
        setContentView(imageView);
    }
}

Tested on Android 22.

JSLT is very close to a JSON equivalent of XSLT. It's a transform language where you write the fixed part of the output in JSON syntax, then insert expressions to compute the values you want to insert in the template.

An example:

It's implemented in Java on top of Jackson.

You can use the following:

Request.Params["paramName"]

You use jarsigner to sign APK's. You don't have to sign with the original keystore, just generate a new one. Read up on the details: http://developer.android.com/guide/publishing/app-signing.html

Structs can have functions just like classes. The only difference is that they are public by default:

struct A {
    void f() {}
};

Additionally, structs can also have constructors and destructors.

struct A {
    A() : x(5) {}
    ~A() {}

    private: int x;
};

Nothing worked and finally got it working using resource @Here and Here; Just remember for OSX Mavericks (10.9) should use PHP 5.4.17 or Stable PHP 5.4.22 source to compile mcrypt. Php Source 5.4.22 here

You can load HTML page partial, in your case is everything inside div#mytable.

setTimeout(function(){
   $( "#mytable" ).load( "your-current-page.html #mytable" );
}, 2000); //refresh every 2 seconds

more information read this http://api.jquery.com/load/

Update Code (if you don't want it auto-refresh)

<button id="refresh-btn">Refresh Table</button>

<script>
$(document).ready(function() {

   function RefreshTable() {
       $( "#mytable" ).load( "your-current-page.html #mytable" );
   }

   $("#refresh-btn").on("click", RefreshTable);

   // OR CAN THIS WAY
   //
   // $("#refresh-btn").on("click", function() {
   //    $( "#mytable" ).load( "your-current-page.html #mytable" );
   // });


});
</script>

Use Addforce() method of a rigidbody compenent, make sure rigidbody is attached to the object and gravity is enabled, something like this

gameObj.rigidbody2D.AddForce(Vector3.up * 10 * Time.deltaTime); or 
gameObj.rigidbody2D.AddForce(Vector3.up * 1000); 

See which combination and what values matches your requirement and use accordingly. Hope it helps

I can see a few reasons to use foreign keys (Orphaned rows, as someone mentioned, are annoying) but I never use them either. With a relatively sane DB schema, I don't think they are 100% needed. Constraints are good, but enforcing them via software is a better method, I think.

Alex

select * from [Table_Name] limit 5

The above snippets don't work for cases with more than 1 day (They are simply ignored).

For this you can use:

function convertMS(ms) {
    var d, h, m, s;
    s = Math.floor(ms / 1000);
    m = Math.floor(s / 60);
    s = s % 60;
    h = Math.floor(m / 60);
    m = m % 60;
    d = Math.floor(h / 24);
    h = h % 24;
    h += d * 24;
    return h + ':' + m + ':' + s;
}

You can achieve this more universally by applying the following CSS:

html,
body {
  height: 100%;
  width: 100%;
  overflow: auto;
}

This allows your content, whatever it is, to become scrollable within body, but be aware that the scrolling context where scroll event is fired is now document.body, not window.

You will want to use the Type.GetType method.

Here is a very simple example:

using System;
using System.Reflection;

class Program
{
    static void Main()
    {
        Type t = Type.GetType("Foo");
        MethodInfo method 
             = t.GetMethod("Bar", BindingFlags.Static | BindingFlags.Public);

        method.Invoke(null, null);
    }
}

class Foo
{
    public static void Bar()
    {
        Console.WriteLine("Bar");
    }
}

I say simple because it is very easy to find a type this way that is internal to the same assembly. Please see Jon's answer for a more thorough explanation as to what you will need to know about that. Once you have retrieved the type my example shows you how to invoke the method.

Just ask it for the objectForKey:@"b". If it returns nil, no object is set at that key.

if ([xyz objectForKey:@"b"]) {
    NSLog(@"There's an object set for key @\"b\"!");
} else {
    NSLog(@"No object set for key @\"b\"");
}

Edit: As to your edited second question, it's simply NSUInteger mCount = [xyz count];. Both of these answers are documented well and easily found in the NSDictionary class reference ([1] [2]).

I'm looking for a function that checks only if it's one of the Latin letters or a decimal number. Since char c = 255, which in printable version is + and considered as a letter by Character.isLetter(c). This function I think is what most developers are looking for:

private static boolean isLetterOrDigit(char c) {
    return (c >= 'a' && c <= 'z') ||
           (c >= 'A' && c <= 'Z') ||
           (c >= '0' && c <= '9');
}

Suspend the process with CTRL+Z then use the command bg to resume it in background. For example:

sleep 60
^Z  #Suspend character shown after hitting CTRL+Z
[1]+  Stopped  sleep 60  #Message showing stopped process info
bg  #Resume current job (last job stopped)

More about job control and bg usage in bash manual page:

JOB CONTROL
Typing the suspend character (typically ^Z, Control-Z) while a process is running causes that process to be stopped and returns control to bash. [...] The user may then manipulate the state of this job, using the bg command to continue it in the background, [...]. A ^Z takes effect immediately, and has the additional side effect of causing pending output and typeahead to be discarded.

bg [jobspec ...]
Resume each suspended job jobspec in the background, as if it had been started with &. If jobspec is not present, the shell's notion of the current job is used.

EDIT

To start a process where you can even kill the terminal and it still carries on running

nohup [command] [-args] > [filename] 2>&1 &

e.g.

nohup /home/edheal/myprog -arg1 -arg2 > /home/edheal/output.txt 2>&1 &

To just ignore the output (not very wise) change the filename to /dev/null

To get the error message set to a different file change the &1 to a filename.

In addition: You can use the jobs command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1 or kill %2 with the number being the index of the process.

If anyone wants to build a viewPager with thumbnails as indicators, using this library could be an option: ThumbIndicator for viewPager that works also with image links as resources.

Just go to Google Fonts - http://www.google.com/fonts/ , add the font you like to your collection, and press the download button. And then just use the @fontface to connect this font to your web page. Btw, if you open the link you are using, you'll see an example of using @fontface

http://fonts.googleapis.com/css?family=Open+Sans:400italic,600italic,400,600,300

For an example

@font-face {
  font-family: 'Open Sans';
  font-style: normal;
  font-weight: 300;
  src: local('Open Sans Light'), local('OpenSans-Light'), url(http://themes.googleusercontent.com/static/fonts/opensans/v6/DXI1ORHCpsQm3Vp6mXoaTaRDOzjiPcYnFooOUGCOsRk.woff) format('woff');
}

Just change the url address to the local link on the font file, you've downloaded.

You can do it even easier.

Just download the file, you've linked:

http://fonts.googleapis.com/css?family=Open+Sans:400italic,600italic,400,600,300

Name it opensans.css or so.

Then just change the links in url() to your path to font files.

And then replace your example string with:

<link href='opensans.css' rel='stylesheet' type='text/css'>

Bash job control involves multiple processes, not multiple threads.

You can execute a command in background with the & suffix.

You can wait for completion of a background command with the wait command.

You can execute multiple commands in parallel by separating them with |. This provides also a synchronization mechanism, since stdout of a command at left of | is connected to stdin of command at right.

In C++, nested classes are not connected to any instance of the outer class. If you want bar to access non-static members of foo, then bar needs to have access to an instance of foo. Maybe something like:

class bar {
  public:
    int getA(foo & f ) {return foo.a;}
};

Or maybe

class bar {
  private:
    foo & f;

  public:
    bar(foo & g)
    : f(g)
    {
    }

    int getA() { return f.a; }
};

In any case, you need to explicitly make sure you have access to an instance of foo.

Addition to Alex' answer:

JavaScript

$(function() {
    $('input[type="submit"]').prop('disabled', true);
    $('#check').on('input', function(e) {
        if(this.value.length === 6) {
            $('input[type="submit"]').prop('disabled', false);
        } else {
            $('input[type="submit"]').prop('disabled', true);
        }
    });
});

HTML

<input type="text" maxlength="6" id="check" data-minlength="6" /><br />
<input type="submit" value="send" />

JsFiddle

But: You should always remember to validate the user input on the server side again. The user could modify the local HTML or disable JavaScript.

CSS transformations create a new stacking context and containing block, as described in the spec. In plain English, this means that fixed position elements with a transformation applied to them will act more like absolutely positioned elements, and z-index values are likely to get screwed with.

If you take a look at this demo, you'll see what I mean. The second div has a transformation applied to it, meaning that it creates a new stacking context, and the pseudo elements are stacked on top rather than below.

So basically, don't do that. Apply a 3D transformation only when you need the optimization. -webkit-font-smoothing: antialiased; is another way to tap into 3D acceleration without creating these problems, but it only works in Safari.

Get client ip using command:

request.remote_ip

Charles is an excellent Web Debugging Proxy for Windows, Mac OS and Linux. The full version is 50$ but it's well worth it.

It is possible to use your usual System.Configuration even in .NET Core 2.0 on Linux. Try this test example:

1. Created a .NET Standard 2.0 Library (say MyLib.dll)
2. Added the NuGet package System.Configuration.ConfigurationManager v4.4.0. This is needed since this package isn't covered by the meta-package NetStandard.Library v2.0.0 (I hope that changes)
3. All your C# classes derived from ConfigurationSection or ConfigurationElement go into MyLib.dll. For example MyClass.cs derives from ConfigurationSection and MyAccount.cs derives from ConfigurationElement. Implementation details are out of scope here but Google is your friend.
4. Create a .NET Core 2.0 app (e.g. a console app, MyApp.dll). .NET Core apps end with .dll rather than .exe in Framework.
5. Create an app.config in MyApp with your custom configuration sections. This should obviously match your class designs in #3 above. For example:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <section name="myCustomConfig" type="MyNamespace.MyClass, MyLib" />
  </configSections>
  <myCustomConfig>
    <myAccount id="007" />
  </myCustomConfig>
</configuration>

That's it - you'll find that the app.config is parsed properly within MyApp and your existing code within MyLib works just fine. Don't forget to run dotnet restore if you switch platforms from Windows (dev) to Linux (test).

Additional workaround for test projects

If you're finding that your App.config is not working in your test projects, you might need this snippet in your test project's .csproj (e.g. just before the ending </Project>). It basically copies App.config into your output folder as testhost.dll.config so dotnet test picks it up.

  <!-- START: This is a buildtime work around for https://github.com/dotnet/corefx/issues/22101 -->
  <Target Name="CopyCustomContent" AfterTargets="AfterBuild">
    <Copy SourceFiles="App.config" DestinationFiles="$(OutDir)\testhost.dll.config" />
  </Target>
  <!-- END: This is a buildtime work around for https://github.com/dotnet/corefx/issues/22101 -->

var is used like public .if a varable is declared like this in a class var $a; if means its scope is public for the class. in simplea words var ~public

var $a;
public

Use

"$filepath"_newstap.sh

or

${filepath}_newstap.sh

or

$filepath\_newstap.sh

_ is a valid character in identifiers. Dot is not, so the shell tried to interpolate $filepath_newstap.

You can use set -u to make the shell exit with an error when you reference an undefined variable.

One thing that I think has been missed in the excellent answers here is the existence if another *.gitignore* or multiple of them.

In a case, I had cloned a repo and could not figure out why a "ignored" file was being added again when running git add. It worked out that there was another .gitignore in a subfolder and that was overriding the one in the root folder.

/.gitignore
/some-folder/.gitignore
/some-folder/this-file-keeps-getting-staged

The

root /.gitignore

was ignoring this-file-keeps-getting-staged

The

/some-folder/.gitignore

did not have a specification to ignore "this-file-keeps-getting-staged" file.

And hence the issue.

One of the things is to simply search for multiple .gitignore files in the hierarchy. And figure out the rules as they apply.

If you are in Mac OS, you need to open the /usr/local/etc/rabbitmq/rabbitmq-env.conf and set NODE_IP_ADDRESS=, it used to be 127.0.0.1. Then add another user as the accepted answer suggested. After that, restart rabbitMQ, brew services restart rabbitmq

The tcpdump tool is available under gnu.

You can use it instead of wireshark.

The following should work:

pip install pywin32

But it didn't for me. I fixed this by downloading and installing the exe from here:

https://github.com/mhammond/pywin32/releases

document.getElementById('myRadio').checked is a boolean value. It should be true or false

document.getElementById('myRadio').checked = "checked"; casts the string to a boolean, which is true.

document.getElementById('myRadio').checked = true; just assigns true without casting.

Use true as it is marginally more efficient and is more intention revealing to maintainers.

In my case (Oracle), it's WHERE REGEXP_LIKE(column, 'regex.*'). See here:

SQL Function

Description

---

REGEXP_LIKE

This function searches a character column for a pattern. Use this function in the WHERE clause of a query to return rows matching the regular expression you specify.

...

REGEXP_REPLACE

This function searches for a pattern in a character column and replaces each occurrence of that pattern with the pattern you specify.

...

REGEXP_INSTR

This function searches a string for a given occurrence of a regular expression pattern. You specify which occurrence you want to find and the start position to search from. This function returns an integer indicating the position in the string where the match is found.

...

REGEXP_SUBSTR

This function returns the actual substring matching the regular expression pattern you specify.

(Of course, REGEXP_LIKE only matches queries containing the search string, so if you want a complete match, you'll have to use '^$' for a beginning (^) and end ($) match, e.g.: '^regex.*$'.)

If you want to use a plain javascript API, there is a good example at https://github.com/hongkiat/js-rss-reader/

The complete description at https://www.hongkiat.com/blog/rss-reader-in-javascript/

It uses fetch method as a global method that asynchronously fetches a resource. Below is a snap of code:

fetch(websiteUrl).then((res) => {
  res.text().then((htmlTxt) => {
    var domParser = new DOMParser()
    let doc = domParser.parseFromString(htmlTxt, 'text/html')
    var feedUrl = doc.querySelector('link[type="application/rss+xml"]').href
  })
}).catch(() => console.error('Error in fetching the website'))

You can use the row_numer() over(partition by ...) syntax like so:

select * from
(
select *
, ROW_NUMBER() OVER(PARTITION BY CName ORDER BY AddressLine) AS row
from myTable
) as a
where row = 1

What this does is that it creates a column called row, which is a counter that increments every time it sees the same CName, and indexes those occurrences by AddressLine. By imposing where row = 1, one can select the CName whose AddressLine comes first alphabetically. If the order by was desc, then it would pick the CName whose AddressLine comes last alphabetically.

I suppose one thing that may be concerning you is whether or not the entries could change, so that the 2 becomes a different number, for instance. You can put your mind at ease here, because in Python, integers are immutable, meaning they cannot change after they are created.

Not everything in Python is immutable, though. For example, lists are mutable---they can change after being created. So for example, if you had a list of lists

>>> a = [[1], [2], [3]]
>>> a[0].append(7)
>>> a
[[1, 7], [2], [3]]

Here, I changed the first entry of a (I added 7 to it). One could imagine shuffling things around, and getting unexpected things here if you are not careful (and indeed, this does happen to everyone when they start programming in Python in some way or another; just search this site for "modifying a list while looping through it" to see dozens of examples).

It's also worth pointing out that x = x + [a] and x.append(a) are not the same thing. The second one mutates x, and the first one creates a new list and assigns it to x. To see the difference, try setting y = x before adding anything to x and trying each one, and look at the difference the two make to y.

If you want a version that raises an error:

"string to search".index("needle") 

If you want a version that returns -1:

"string to search".find("needle") 

This is more efficient than the 'in' syntax

Try this code, hope it will help you

String regex = "(\\d+)(\\.)?(\\d+)?";  for integer and decimal like 232 232.12 

To reset a specific file to the last-committed state (to discard uncommitted changes in a specific file):

git checkout thefiletoreset.txt

This is mentioned in the git status output:

(use "git checkout -- <file>..." to discard changes in working directory)

To reset the entire repository to the last committed state:

git reset --hard

To remove untracked files, I usually just delete all files in the working copy (but not the .git/ folder!), then do git reset --hard which leaves it with only committed files.

A better way is to use git clean (warning: using the -x flag as below will cause Git to delete ignored files):

git clean -d -x -f

will remove untracked files, including directories (-d) and files ignored by git (-x). Replace the -f argument with -n to perform a dry-run or -i for interactive mode, and it will tell you what will be removed.

Relevant links:

• git-reset man page
• git-clean man page
• git ready "cleaning up untracked files" (as Marko posted)
• Stack Overflow question "How to remove local (untracked) files from the current Git working tree")

In regards to PowerShell 5.1 (this is so much easier in PowerShell 7)...

Operating off the assumption that we have a file named jsonConfigFile.json with the following content from your post:

{
    "Stuffs": [
        {
            "Name": "Darts",
            "Type": "Fun Stuff"
        },
        {
            "Name": "Clean Toilet",
            "Type": "Boring Stuff"
        }
    ]
}

This will create an ordered hashtable from a JSON file to help make retrieval easier:

$json = [ordered]@{}

(Get-Content "jsonConfigFile.json" -Raw | ConvertFrom-Json).PSObject.Properties |
    ForEach-Object { $json[$_.Name] = $_.Value }

$json.Stuffs will list a nice hashtable, but it gets a little more complicated from here. Say you want the Type key's value associated with the Clean Toilet key, you would retrieve it like this:

$json.Stuffs.Where({$_.Name -eq "Clean Toilet"}).Type

It's a pain in the ass, but if your goal is to use JSON on a barebones Windows 10 installation, this is the best way to do it as far as I've found.

Making a small adjustment to Tor Valamo's solution to fix the problem noticed by Dominic Rodger, you could use:

// Remove anything which isn't a word, whitespace, number
// or any of the following caracters -_~,;[]().
// If you don't need to handle multi-byte characters
// you can use preg_replace rather than mb_ereg_replace
// Thanks @Lukasz Rysiak!
$file = mb_ereg_replace("([^\w\s\d\-_~,;\[\]\(\).])", '', $file);
// Remove any runs of periods (thanks falstro!)
$file = mb_ereg_replace("([\.]{2,})", '', $file);

AFAIK, there is no way to do this reliably, unless you switch to an array. Which honestly, doesn't seem strange - it's seems pretty straight forward to me that arrays are countable, and objects aren't.

Probably the closest you'll get is something like this

// Monkey patching on purpose to make a point
Object.prototype.length = function()
{
  var i = 0;
  for ( var p in this ) i++;
  return i;
}

alert( {foo:"bar", bar: "baz"}.length() ); // alerts 3

But this creates problems, or at least questions. All user-created properties are counted, including the _length function itself! And while in this simple example you could avoid it by just using a normal function, that doesn't mean you can stop other scripts from doing this. so what do you do? Ignore function properties?

Object.prototype.length = function()
{
  var i = 0;
  for ( var p in this )
  {
      if ( 'function' == typeof this[p] ) continue;
      i++;
  }
  return i;
}

alert( {foo:"bar", bar: "baz"}.length() ); // alerts 2

In the end, I think you should probably ditch the idea of making your objects countable and figure out another way to do whatever it is you're doing.

Speaking for current (2021-2) Java versions there is still the old ISO-8859-1 function utils.Properties#load.

• If you use Properties.load you must use ISO-8859-1.
• If you use ResourceBundle than UTF-8 should be fine.

Allow me to quote from the official doc.

PropertyResourceBundle

PropertyResourceBundle can be constructed either from an InputStream or a Reader, which represents a property file. Constructing a PropertyResourceBundle instance from an InputStream requires that the input stream be encoded in UTF-8. By default, if a MalformedInputException or an UnmappableCharacterException occurs on reading the input stream, then the PropertyResourceBundle instance resets to the state before the exception, re-reads the input stream in ISO-8859-1, and continues reading. If the system property java.util.PropertyResourceBundle.encoding is set to either "ISO-8859-1" or "UTF-8", the input stream is solely read in that encoding, and throws the exception if it encounters an invalid sequence. If "ISO-8859-1" is specified, characters that cannot be represented in ISO-8859-1 encoding must be represented by Unicode Escapes as defined in section 3.3 of The Java™ Language Specification whereas the other constructor which takes a Reader does not have that limitation. Other encoding values are ignored for this system property. The system property is read and evaluated when initializing this class. Changing or removing the property has no effect after the initialization.

https://docs.oracle.com/en/java/javase/14/docs/api/java.base/java/util/PropertyResourceBundle.html

Properties#load

Reads a property list (key and element pairs) from the input byte stream. The input stream is in a simple line-oriented format as specified in load(Reader) and is assumed to use the ISO 8859-1 character encoding; that is each byte is one Latin1 character. Characters not in Latin1, and certain special characters, are represented in keys and elements using Unicode escapes as defined in section 3.3 of The Java™ Language Specification.

https://docs.oracle.com/en/java/javase/14/docs/api/java.base/java/util/Properties.html#load(java.io.InputStream)

I Did that and it works for redirecting to other view I think If you add the #sectionLink after It will work

<a class="btn yellow" href="/users/Create/@Model.Id" target="_blank">
                                        Add As User
                                    </a>

'Use of Unresolved Identifier' in Swift my also happen when you forgot to import a library. For example I have the error:

In which I forgot the UIKit

import UIKit

The errors in ASP.Net are saved on the Server.GetLastError property,

Or i would put a label on the asp.net page for displaying the error.

try
{
    do something
}
catch (YourException ex)
{
    errorLabel.Text = ex.Message;
    errorLabel.Visible = true;
}

$("a:lt(n)")

JQuery Documentation

You have to add Button to excel sheet(say sheet1) from which you can go to another sheet(say sheet2).

Button can be added from Developer tab in excel. If developer tab is not there follow below steps to enable.

GOTO file -> options -> Customize Ribbon -> enable checkbox of developer on right panel -> Done.

To Add button :-

Developer Tab -> Insert -> choose first item button -> choose location of button-> Done.

To give name for button :-

Right click on button -> edit text.

To add code for going to sheet2 :-

Right click on button -> Assign Macro -> New -> (microsoft visual basic will open to code for button) -> paste below code

Worksheets("Sheet2").Visible = True
Worksheets("Sheet2").Activate

Save the file using 'Excel Macro Enable Template(*.xltm)' By which the code is appended with excel sheet.

I was also having the same problem. This is a method I wrote to ask the user for an input and not accept the input unless its an integer. Please note that I am a beginner so if the code is not working as expected, blame my inexperience !

private int numberValue(String value, boolean val) throws IOException {
    //prints the value passed by the code implementer
    System.out.println(value);
    //returns 0 is val is passed as false
    Object num = 0;
    while (val) {
        num = br.readLine();
        try {
            Integer numVal = Integer.parseInt((String) num);
            if (numVal instanceof Integer) {
                val = false;
                num = numVal;
            }
        } catch (Exception e) {
            System.out.println("Error. Please input a valid number :-");
        }
    }
    return ((Integer) num).intValue();
}

The easiest way would be to do

npm list -g

to list the package and view their installed location.

I had installed npm via chololatey, so the location is

C:\MyProgramData\chocolatey\lib\nodejs.commandline.0.10.31\tools\node_modules

C:\MyProgramData\ is chocolatey repo location.

Sometimes there is permission errors. Try:

sudo pip install simplejson

Hope it helps.

Use calendar.monthrange:

>>> from calendar import monthrange
>>> monthrange(2011, 2)
(1, 28)

Just to be clear, monthrange supports leap years as well:

>>> from calendar import monthrange
>>> monthrange(2012, 2)
(2, 29)

As @mikhail-pyrev mentions in a comment:

First number is weekday of first day of the month, second number is number of days in said month.

preg_match_all('!\d+!', $some_string, $matches);
$string_of_numbers = implode(' ', $matches[0]);

The first argument in implode in this specific case says "separate each element in matches[0] with a single space." Implode will not put a space (or whatever your first argument is) before the first number or after the last number.

Something else to note is $matches[0] is where the array of matches (that match this regular expression) found are stored.

For further clarification on what the other indexes in the array are for see: http://php.net/manual/en/function.preg-match-all.php

I'm assuming you're talking about com.google.common.base.Predicate<T> from Guava.

From the API:

Determines a true or false value for a given input. For example, a RegexPredicate might implement Predicate<String>, and return true for any string that matches its given regular expression.

This is essentially an OOP abstraction for a boolean test.

For example, you may have a helper method like this:

static boolean isEven(int num) {
   return (num % 2) == 0; // simple
}

Now, given a List<Integer>, you can process only the even numbers like this:

    List<Integer> numbers = Arrays.asList(1,2,3,4,5,6,7,8,9,10);
    for (int number : numbers) {
        if (isEven(number)) {
            process(number);
        }
    }

With Predicate, the if test is abstracted out as a type. This allows it to interoperate with the rest of the API, such as Iterables, which have many utility methods that takes Predicate.

Thus, you can now write something like this:

    Predicate<Integer> isEven = new Predicate<Integer>() {
        @Override public boolean apply(Integer number) {
            return (number % 2) == 0;
        }               
    };
    Iterable<Integer> evenNumbers = Iterables.filter(numbers, isEven);

    for (int number : evenNumbers) {
        process(number);
    }

Note that now the for-each loop is much simpler without the if test. We've reached a higher level of abtraction by defining Iterable<Integer> evenNumbers, by filter-ing using a Predicate.

API links

• Iterables.filter
  • Returns the elements that satisfy a predicate.

On higher-order function

Predicate allows Iterables.filter to serve as what is called a higher-order function. On its own, this offers many advantages. Take the List<Integer> numbers example above. Suppose we want to test if all numbers are positive. We can write something like this:

static boolean isAllPositive(Iterable<Integer> numbers) {
    for (Integer number : numbers) {
        if (number < 0) {
            return false;
        }
    }
    return true;
}

//...
if (isAllPositive(numbers)) {
    System.out.println("Yep!");
}

With a Predicate, and interoperating with the rest of the libraries, we can instead write this:

Predicate<Integer> isPositive = new Predicate<Integer>() {
    @Override public boolean apply(Integer number) {
        return number > 0;
    }       
};

//...
if (Iterables.all(numbers, isPositive)) {
    System.out.println("Yep!");
}

Hopefully you can now see the value in higher abstractions for routines like "filter all elements by the given predicate", "check if all elements satisfy the given predicate", etc make for better code.

Unfortunately Java doesn't have first-class methods: you can't pass methods around to Iterables.filter and Iterables.all. You can, of course, pass around objects in Java. Thus, the Predicate type is defined, and you pass objects implementing this interface instead.

You should map your virtual network drive in Windows.

1. Open command prompt in Windows (VirtualBox)
2. Execute: net use x: \\vboxsvr\<your_shared_folder_name>
3. You should see new drive X: in My Computer

In your case execute net use x: \\vboxsvr\win7

An EXE is visible to the system as a regular Win32 executable. Its entry point refers to a small loader which initializes the .NET runtime and tells it to load and execute the assembly contained in the EXE. A DLL is visible to the system as a Win32 DLL but most likely without any entry points. The .NET runtime stores information about the contained assembly in its own header.

dll is a collection of reusable functions where as an .exe is an executable which may call these functions

Despite the imprecise nature of the question, here's my interpretive answer.

var html = [
    '<div> A line</div>',
    '<div> Add more lines</div>',
    '<div> To the array as you need.</div>'
].join('');

var div = document.createElement('div');
    div.setAttribute('class', 'post block bc2');
    div.innerHTML = html;
    document.getElementById('posts').appendChild(div);

Yes, there is a module fs-extra. There is a method .emptyDir() inside this module which does the job. Here is an example:

const fsExtra = require('fs-extra')

fsExtra.emptyDirSync(fileDir)

There is also an asynchronous version of this module too. Anyone can check out the link.

Use repr()[1:-1]. In this case, the double quotes don't need to be escaped. The [-1:1] slice is to remove the single quote from the beginning and the end.

>>> x = raw_input()
I'm "stuck" :\
>>> print x
I'm "stuck" :\
>>> print repr(x)[1:-1]
I\'m "stuck" :\\

Or maybe you just want to escape a phrase to paste into your program? If so, do this:

>>> raw_input()
I'm "stuck" :\
'I\'m "stuck" :\\'

The container's IP address should be properly configured inside of its network namespace, so any of the standard linux tools can get it. For example, try ifconfig, ip addr show, hostname -I, etc. from an attached shell within one of your containers to test it out.

To generate a shared library you need first to compile your C code with the -fPIC (position independent code) flag.

gcc -c -fPIC hello.c -o hello.o

This will generate an object file (.o), now you take it and create the .so file:

gcc hello.o -shared -o libhello.so

EDIT: Suggestions from the comments:

You can use

gcc -shared -o libhello.so -fPIC hello.c

to do it in one step. – Jonathan Leffler

I also suggest to add -Wall to get all warnings, and -g to get debugging information, to your gcc commands. – Basile Starynkevitch

You cannot redeclare any functions in PHP. You can, however, override them. Check out overriding functions as well as renaming functions in order to save the function you're overriding if you want.

So, keep in mind that when you override a function, you lose it. You may want to consider keeping it, but in a different name. Just saying.

Also, if these are functions in classes that you're wanting to override, you would just need to create a subclass and redeclare the function in your class without having to do rename_function and override_function.

Example:

rename_function('mysql_connect', 'original_mysql_connect' );
override_function('mysql_connect', '$a,$b', 'echo "DOING MY FUNCTION INSTEAD"; return $a * $b;');

You can access the Image File and data from a form using MULTIPART FORM DATA By using the below code.

@POST
@Path("/UpdateProfile")
@Consumes(value={MediaType.APPLICATION_JSON,MediaType.MULTIPART_FORM_DATA})
@Produces(value={MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML})
public Response updateProfile(
    @FormDataParam("file") InputStream fileInputStream,
    @FormDataParam("file") FormDataContentDisposition contentDispositionHeader,
    @FormDataParam("ProfileInfo") String ProfileInfo,
    @FormDataParam("registrationId") String registrationId) {

    String filePath= "/filepath/"+contentDispositionHeader.getFileName();

    OutputStream outputStream = null;
    try {
        int read = 0;
        byte[] bytes = new byte[1024];
        outputStream = new FileOutputStream(new File(filePath));

        while ((read = fileInputStream.read(bytes)) != -1) {
            outputStream.write(bytes, 0, read);
        }

        outputStream.flush();
        outputStream.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (outputStream != null) { 
            try {
                outputStream.close();
            } catch(Exception ex) {}
        }
    }
}

If you want multiple background images but don't want them to overlap, you can use this CSS:

body {
  font-size: 13px;
  font-family:Century Gothic, Helvetica, sans-serif;
  color: #333;
  text-align: center;
  margin:0px;
  padding: 25px;
}

#topshadow {
  height: 62px
  width:1030px;
  margin: -62px
  background-image: url(images/top-shadow.png);
}

#pageborders {
width:1030px;
min-height:100%;
margin:auto;        
    background:url(images/mid-shadow.png);
}

#bottomshadow {
    margin:0px;
height:66px;
width:1030px;
background:url(images/bottom-shadow.png);
}

#page {
  text-align: left;
  margin:62px, 0px, 20px;
  background-color: white;
  margin:auto;
  padding:0px;
  width:1000px;
}

with this HTML structure:

<body 

<?php body_class(); ?>>

  <div id="topshadow">
  </div>

  <div id="pageborders">

    <div id="page">
    </div>
  </div>
</body>

I think this should be much easier to use:

select ISNULL(sum(field),0) from tablename

If you're in a situation where you don't have control over whether part of the condition is checking a nullable value, you can always try the following:

if( someInt == 6 && someNullableBool == null ? false : (bool)someNullableBool){
    //perform your actions if true
}

I know it's not exactly a purist approach putting a ternary in an if statement but it does resolve the issue cleanly.

This is, of course, a manual way of saying GetValueOrDefault(false)

The simplest one got to be:

def html = "http://google.com".toURL().text

What is the best approach to do this JAVA?

I would personally NOT use Axis 2, even for client side development only. Here is why I stay away from it:

1. I don't like its architecture and hate its counter productive deployment model.
2. I find it to be low quality project.
3. I don't like its performances (see this benchmark against JAX-WS RI).
4. It's always a nightmare to setup dependencies (I use Maven and I always have to fight with the gazillion of dependencies) (see #2)
5. Axis sucked big time and Axis2 isn't better. No, this is not a personal opinion, there is a consensus.
6. I suffered once, never again.

The only reason Axis is still around is IMO because it's used in Eclipse since ages. Thanks god, this has been fixed in Eclipse Helios and I hope Axis2 will finally die. There are just much better stacks.

I read about SAAJ, looks like that will be more granular level of approach?

To do what?

Is there any other way than using the WSDL2Java tool, to generate the code. Maybe wsimport in another option. What are the pros and cons?

Yes! Prefer a JAX-WS stack like CXF or JAX-WS RI (you might also read about Metro, Metro = JAX-WS RI + WSIT), they are just more elegant, simpler, easier to use. In your case, I would just use JAX-WS RI which is included in Java 6 and thus wsimport.

Can someone send the links for some good tutorials on these topics?

That's another pro, there are plenty of (good quality) tutorials for JAX-WS, see for example:

• Developing JAX-WS Web Service Clients (start here)
• Introducing JAX-WS 2.0 With the Java SE 6 Platform, Part 1
• Creating a Simple Web Service and Client with JAX-WS
• Creating a SOAP client with either Apache CXF or GlassFish Metro (Glen Mazza's blog is a great resources)

What are the options we need to use while generating the code using the WSDL2Java?

No options, use wsimport :)

Why are you doing a group by on an update statement? Are you sure that's not the part that's causing the query to fail? Try this:

update 
    MasterTbl
set
    TotalX = Sum(DetailTbl.X),
    TotalY = Sum(DetailTbl.Y),
    TotalZ = Sum(DetailTbl.Z)
from
    DetailTbl
where
    DetailTbl.MasterID = MasterID

If you want wrap your text, then you should draw your text in a rectangle:

RectangleF rectF1 = new RectangleF(30, 10, 100, 122);
e.Graphics.DrawString(text1, font1, Brushes.Blue, rectF1);

See: https://msdn.microsoft.com/en-us/library/baw6k39s(v=vs.110).aspx

Oneliner:

obj = (function(attr, val){ var a = {}; a[attr]=val; return a; })('hash', 5);

Or:

attr = 'hash';
val = 5;
var obj = (obj={}, obj[attr]=val, obj);

Anything shorter?

This solution worked for me.

input:focus {
    outline: none !important;
    box-shadow: none !important;
}

You can try

SELECT ROUND((SYSDATE - TO_DATE('12-MAY-16'))/365.25, 5) AS AGE from DUAL;

You can configure ROUND to show as many decimal places as you wish.

Placing the date in decimal format like aforementioned helps with calculations of age groups, etc.

This is just a contrived example. In real world scenarios, you wouldn't be converting strings to date using TO_DATE.

However, if you have date of birth in date format, you can subtract two dates safely.

import org.apache.commons.io.FileUtils;   

List<File> htmFileList = new ArrayList<File>();

for (File file : (List<File>) FileUtils.listFiles(new File(srcDir), new String[]{"txt", "TXT"}, true)) {
    htmFileList.add(file);
}

This is my latest code to add all text files from a directory

Recently I was learning about chrono library and thought of implementing a sleep function on my own. Here is the code,

#include <cmath>
#include <chrono>

template <typename rep = std::chrono::seconds::rep, 
          typename period = std::chrono::seconds::period>
void sleep(std::chrono::duration<rep, period> sec)
{
    using sleep_duration = std::chrono::duration<long double, std::nano>;

    std::chrono::steady_clock::time_point start = std::chrono::steady_clock::now();
    std::chrono::steady_clock::time_point end = std::chrono::steady_clock::now();

    long double elapsed_time = 
    std::chrono::duration_cast<sleep_duration>(end - start).count();

    long double sleep_time = 
    std::chrono::duration_cast<sleep_duration>(sec).count();

    while (std::isgreater(sleep_time, elapsed_time)) {
        end = std::chrono::steady_clock::now();
        elapsed_time = std::chrono::duration_cast<sleep_duration>(end - start).count(); 
    }
}

We can use it with any std::chrono::duration type (By default it takes std::chrono::seconds as argument). For example,

#include <cmath>
#include <chrono>

template <typename rep = std::chrono::seconds::rep, 
          typename period = std::chrono::seconds::period>
void sleep(std::chrono::duration<rep, period> sec)
{
    using sleep_duration = std::chrono::duration<long double, std::nano>;

    std::chrono::steady_clock::time_point start = std::chrono::steady_clock::now();
    std::chrono::steady_clock::time_point end = std::chrono::steady_clock::now();

    long double elapsed_time = 
    std::chrono::duration_cast<sleep_duration>(end - start).count();

    long double sleep_time = 
    std::chrono::duration_cast<sleep_duration>(sec).count();

    while (std::isgreater(sleep_time, elapsed_time)) {
        end = std::chrono::steady_clock::now();
        elapsed_time = std::chrono::duration_cast<sleep_duration>(end - start).count(); 
    }
}

using namespace std::chrono_literals;
int main (void) {
    std::chrono::steady_clock::time_point start1 = std::chrono::steady_clock::now();
    
    sleep(5s);  // sleep for 5 seconds
    
    std::chrono::steady_clock::time_point end1 = std::chrono::steady_clock::now();
    
    std::cout << std::setprecision(9) << std::fixed;
    std::cout << "Elapsed time was: " << std::chrono::duration_cast<std::chrono::seconds>(end1-start1).count() << "s\n";
    
    std::chrono::steady_clock::time_point start2 = std::chrono::steady_clock::now();

    sleep(500000ns);  // sleep for 500000 nano seconds/500 micro seconds
    // same as writing: sleep(500us)
    
    std::chrono::steady_clock::time_point end2 = std::chrono::steady_clock::now();
    
    std::cout << "Elapsed time was: " << std::chrono::duration_cast<std::chrono::microseconds>(end2-start2).count() << "us\n";
    return 0;
}

For more information, visit https://en.cppreference.com/w/cpp/header/chrono and see this cppcon talk of Howard Hinnant, https://www.youtube.com/watch?v=P32hvk8b13M. He has two more talks on chrono library. And you can always use the library function, std::this_thread::sleep_for

Note: Outputs may not be accurate. So, don't expect it to give exact timings.

Fetch vs Pull

Git fetch just updates your repo data, but a git pull will basically perform a fetch and then merge the branch pulled

What is the difference between 'git pull' and 'git fetch'?

Merge vs Rebase

from Atlassian SourceTree Blog, Merge or Rebase:

Merging brings two lines of development together while preserving the ancestry of each commit history.

In contrast, rebasing unifies the lines of development by re-writing changes from the source branch so that they appear as children of the destination branch – effectively pretending that those commits were written on top of the destination branch all along.

Also, check out Learn Git Branching, which is a nice game that has just been posted to HackerNews (link to post) and teaches a lot of branching and merging tricks. I believe it will be very helpful in this matter.

Best way is to use the Carbon dependency.

With Carbon\Carbon::now(); you get the current Datetime.

With Carbon you can do like enything with the DateTime. Event things like this:

$tomorrow = Carbon::now()->addDay();
$lastWeek = Carbon::now()->subWeek();

For Java < 7 you can use if-else along with Exception:

try {
    // common logic to handle both exceptions
} catch (Exception ex) {
    if (ex instanceof Exception1 || ex instanceof Exception2) {

    }
    else {
        throw ex;
        // or if you don't want to have to declare Exception use
        // throw new RuntimeException(ex);
    }
}

Edited and replaced Throwable with Exception.

In AspNetCore web api, this issue got fixed by adding "Microsoft.AspNetCore.Cors" (ver 1.1.1) and adding the below changes on Startup.cs.

public void ConfigureServices(IServiceCollection services)
{ 
    services.AddCors(options =>
    {
          options.AddPolicy("AllowAllHeaders",
                builder =>
            {
                    builder.AllowAnyOrigin()
                           .AllowAnyHeader()
                           .AllowAnyMethod();
                });
    });
    .
    .
    .
}

and

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{


    // Shows UseCors with named policy.
    app.UseCors("AllowAllHeaders");
    .
    .
    .
}

and putting [EnableCors("AllowAllHeaders")] on the controller.

Panagiotis Kanavos is right, sometimes copy and paste T-SQL can make appear unwanted characters...

I finally found a simple and fast way (only Notepad++ needed) to detect which character is wrong, without having to manually rewrite the whole statement: there is no need to save any file to disk.

It's pretty quick, in Notepad++:

• Click "New file"
• Check under the menu "Encoding": the value should be "Encode in UTF-8"; set it if it's not
• Paste your text
• From Encoding menu, now click "Encode in ANSI" and check again your text

You should easily find the wrong character(s)

In case anyone else runs into this, I took WhoIsRich's example and modified it a bit. When calling ReadReg I needed to do the following: ReadReg("App", "HKEY_CURRENT_USER\App\Version") which would then be able to read the version number from the registry, if it existed. I also am using HKCU since it does not require admin privileges to write to.

Function ReadReg(RegKey, RegPath)
      Const HKEY_CURRENT_USER = &H80000001
      Dim objRegistry, oReg
      Set objRegistry = CreateObject("Wscript.shell")
      Set oReg = GetObject("winmgmts:!root\default:StdRegProv")

      if oReg.EnumKey(HKEY_CURRENT_USER, RegKey) = 0 Then
        ReadReg = objRegistry.RegRead(RegPath)
      else
        ReadReg = ""
      end if
End Function

This indicates the linux has delivered a SIGTERM to your process. This is usually at the request of some other process (via kill()) but could also be sent by your process to itself (using raise()). This signal requests an orderly shutdown of your process.

If you need a quick cheatsheet of signal numbers, open a bash shell and:

$ kill -l
 1) SIGHUP   2) SIGINT   3) SIGQUIT  4) SIGILL
 5) SIGTRAP  6) SIGABRT  7) SIGBUS   8) SIGFPE
 9) SIGKILL 10) SIGUSR1 11) SIGSEGV 12) SIGUSR2
13) SIGPIPE 14) SIGALRM 15) SIGTERM 16) SIGSTKFLT
17) SIGCHLD 18) SIGCONT 19) SIGSTOP 20) SIGTSTP
21) SIGTTIN 22) SIGTTOU 23) SIGURG  24) SIGXCPU
25) SIGXFSZ 26) SIGVTALRM   27) SIGPROF 28) SIGWINCH
29) SIGIO   30) SIGPWR  31) SIGSYS  34) SIGRTMIN
35) SIGRTMIN+1  36) SIGRTMIN+2  37) SIGRTMIN+3  38) SIGRTMIN+4
39) SIGRTMIN+5  40) SIGRTMIN+6  41) SIGRTMIN+7  42) SIGRTMIN+8
43) SIGRTMIN+9  44) SIGRTMIN+10 45) SIGRTMIN+11 46) SIGRTMIN+12
47) SIGRTMIN+13 48) SIGRTMIN+14 49) SIGRTMIN+15 50) SIGRTMAX-14
51) SIGRTMAX-13 52) SIGRTMAX-12 53) SIGRTMAX-11 54) SIGRTMAX-10
55) SIGRTMAX-9  56) SIGRTMAX-8  57) SIGRTMAX-7  58) SIGRTMAX-6
59) SIGRTMAX-5  60) SIGRTMAX-4  61) SIGRTMAX-3  62) SIGRTMAX-2
63) SIGRTMAX-1  64) SIGRTMAX    

You can determine the sender by using an appropriate signal handler like:

#include <signal.h>
#include <stdio.h>
#include <stdlib.h>

void sigterm_handler(int signal, siginfo_t *info, void *_unused)
{
  fprintf(stderr, "Received SIGTERM from process with pid = %u\n",
      info->si_pid);
  exit(0);
}

int main (void)
{
  struct sigaction action = {
    .sa_handler = NULL,
    .sa_sigaction = sigterm_handler,
    .sa_mask = 0,
    .sa_flags = SA_SIGINFO,
    .sa_restorer = NULL
  };

  sigaction(SIGTERM, &action, NULL);
  sleep(60);

  return 0;
}

Notice that the signal handler also includes a call to exit(). It's also possible for your program to continue to execute by ignoring the signal, but this isn't recommended in general (if it's a user doing it there's a good chance it will be followed by a SIGKILL if your process doesn't exit, and you lost your opportunity to do any cleanup then).

The test for undefined is unnecessary and isn't as robust as it could be because, as user568458 pointed out, the solution provided fails if null or false is passed. Users of your API might think false or null would force the method to avoid that parameter.

function PaulDixonSolution(required, optionalArg){
   optionalArg = (typeof optionalArg === "undefined") ? "defaultValue" : optionalArg;
   console.log(optionalArg);
};
PaulDixonSolution("required");
PaulDixonSolution("required", "provided");
PaulDixonSolution("required", null);
PaulDixonSolution("required", false);

The result is:

defaultValue
provided
null
false

Those last two are potentially bad. Instead try:

function bulletproof(required, optionalArg){
   optionalArg = optionalArg ? optionalArg : "defaultValue";;
   console.log(optionalArg);
};
bulletproof("required");
bulletproof("required", "provided");
bulletproof("required", null);
bulletproof("required", false);

Which results in:

defaultValue
provided
defaultValue
defaultValue

The only scenario where this isn't optimal is when you actually have optional parameters that are meant to be booleans or intentional null.

It's a really weird issue and I am posting this after wasting my 2 hours.

You installed Python and added it to PATH. You've checked it too(like 64-bit etc). Everything should work but it is not.

what you didn't do is a terminal/cmd restart

restart your terminal and everything would work like a charm.

I Hope, it helped/might help others.

How to stop a thread created by implementing runnable interface?

There are many ways that you can stop a thread but all of them take specific code to do so. A typical way to stop a thread is to have a volatile boolean shutdown field that the thread checks every so often:

  // set this to true to stop the thread
  volatile boolean shutdown = false;
  ...
  public void run() {
      while (!shutdown) {
          // continue processing
      }
  }

You can also interrupt the thread which causes sleep(), wait(), and some other methods to throw InterruptedException. You also should test for the thread interrupt flag with something like:

  public void run() {
      while (!Thread.currentThread().isInterrupted()) {
          // continue processing
          try {
              Thread.sleep(1000);
          } catch (InterruptedException e) {
              // good practice
              Thread.currentThread().interrupt();
              return;
          }
      }
  }

Note that that interrupting a thread with interrupt() will not necessarily cause it to throw an exception immediately. Only if you are in a method that is interruptible will the InterruptedException be thrown.

If you want to add a shutdown() method to your class which implements Runnable, you should define your own class like:

public class MyRunnable implements Runnable {
    private volatile boolean shutdown;
    public void run() {
        while (!shutdown) {
            ...
        }
    }
    public void shutdown() {
        shutdown = true;
    }
}

CSS selection and applying style to a particular element can be done through traversing through the dom element [Example

Example

.a .b .c .d{
    background: #bdbdbd;
}
div>div>div>div:last-child{
    background: red;
}

<div class='a'>The first paragraph.
 <div class='b'>The second paragraph.
  <div class='c'>The third paragraph.
   <div class='d'>The fourth paragraph.</div>
   <div class='e'>The fourth paragraph.</div>
  </div>
 </div>
</div>

An object associated with a composition relationship will not exist outside the containing object. Examples are an Appointment and the owner (a Person) or a Calendar; a TestResult and a Patient.

On the other hand, an object that is aggregated by a containing object can exist outside that containing object. Examples are a Door and a House; an Employee and a Department.

A dependency relates to collaboration or delegation, where an object requests services from another object and is therefor dependent on that object. As the client of the service, you want the service interface to remain constant, even if future services are offered.

I believe you need to specify "Option Infer On" for this to work.

Option Infer allows the compiler to make a guess at what is being represented by your code, thus it will guess that {"stuff"} is an array of strings. With "Option Infer Off", {"stuff"} won't have any type assigned to it, ever, and so it will always fail, without a type specifier.

Option Infer is, I think On by default in new projects, but Off by default when you migrate from earlier frameworks up to 3.5.

Opinion incoming:

Also, you mention that you've got "Option Explicit Off". Please don't do this.

Setting "Option Explicit Off" means that you don't ever have to declare variables. This means that the following code will silently and invisibly create the variable "Y":

Dim X as Integer
Y = 3

This is horrible, mad, and wrong. It creates variables when you make typos. I keep hoping that they'll remove it from the language.

Use a CountDownLatch.

It's from java.util.concurrent and it's exactly the way to wait for several threads to complete execution before continuing.

In order to achieve the callback effect you're looking after, that does require a little additional extra work. Namely, handling this by yourself in a separate thread which uses the CountDownLatch and does wait on it, then goes on about notifying whatever it is you need to notify. There is no native support for callback, or anything similar to that effect.

EDIT: now that I further understand your question, I think you are reaching too far, unnecessarily. If you take a regular SingleThreadExecutor, give it all the tasks, and it will do the queueing natively.

I thought the regular modulus operator would work for this in java, but it can't be hard to code. Just divide the numerator by the denominator, and take the integer portion of the result. Multiply that by the denominator, and subtract the result from the numerator.

x = n / d
xint = Integer portion of x
result = n - d * xint

The problem in my case was Jackson was trying to serialize an empty object with no attributes nor methods.

As suggested in the exception I added the following line to avoid failure on empty beans:

For Jackson 1.9

myObjectMapper.configure(SerializationConfig.Feature.FAIL_ON_EMPTY_BEANS, false);

For Jackson 2.X

myObjectMapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);

You can find a simple example on jackson disable fail_on_empty_beans

The javascript array has a constructor that accepts the length of the array:

let arr = new Array<number>(3);
console.log(arr); // [undefined × 3]

However, this is just the initial size, there's no restriction on changing that:

arr.push(5);
console.log(arr); // [undefined × 3, 5]

Typescript has tuple types which let you define an array with a specific length and types:

let arr: [number, number, number];

arr = [1, 2, 3]; // ok
arr = [1, 2]; // Type '[number, number]' is not assignable to type '[number, number, number]'
arr = [1, 2, "3"]; // Type '[number, number, string]' is not assignable to type '[number, number, number]'

To stop a service, you have to find service name using:

adb shell dumpsys activity services <your package>

for example: adb shell dumpsys activity services com.xyz.something

This will list services running for your package.
Output should be similar to:

ServiceRecord{xxxxx u0 com.xyz.something.beta/xyz.something.abc.XYZService}

Now select your service and run:

adb shell am stopservice <service_name> 

For example:

adb shell am stopservice com.xyz.something.beta/xyz.something.abc.XYZService

similarly, to start service:

adb shell am startservice <service_name>

To access service, your service(in AndroidManifest.xml) should set exported="true"

<!-- Service declared in manifest -->
<service
    android:name=".YourServiceName"
    android:exported="true"
    android:launchMode="singleTop">
    <intent-filter>
        <action android:name="com.your.package.name.YourServiceName"/>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</service>

Assuming you don't have extraneous whitespace:

with open('file') as f:
    w, h = [int(x) for x in next(f).split()] # read first line
    array = []
    for line in f: # read rest of lines
        array.append([int(x) for x in line.split()])

You could condense the last for loop into a nested list comprehension:

with open('file') as f:
    w, h = [int(x) for x in next(f).split()]
    array = [[int(x) for x in line.split()] for line in f]

1. Open Google Chrome.
2. Click Menu on the upper right side. Beside the STAR symbol (Bookmark).
3. Click Show Advanced Settings.
4. Scroll down and find Network.
5. Click Change proxy settings.
6. On the Connections tab, click LAN settings.
7. Uncheck "Use a proxy server for your LAN."
8. Then click OK.

Hope it helps .

This is not possible if you can't change your code. But I like dependency injection and Mockito supports it:

public class First {    
    @Resource
    Second second;

    public First() {
        second = new Second();
    }

    public String doSecond() {
        return second.doSecond();
    }
}

Your test:

@RunWith(MockitoJUnitRunner.class)
public class YourTest {
   @Mock
   Second second;

   @InjectMocks
   First first = new First();

   public void testFirst(){
      when(second.doSecond()).thenReturn("Stubbed Second");
      assertEquals("Stubbed Second", first.doSecond());
   }
}

This is very nice and easy.

public static class SettingsExtensions
{
    public static bool TryGetValue<T>(this Settings settings, string key, out T value)
    {
        if (settings.Properties[key] != null)
        {
            value = (T) settings[key];
            return true;
        }

        value = default(T);
        return false;
    }

    public static bool ContainsKey(this Settings settings, string key)
    {
        return settings.Properties[key] != null;
    }

    public static void SetValue<T>(this Settings settings, string key, T value)
    {
        if (settings.Properties[key] == null)
        {
            var p = new SettingsProperty(key)
            {
                PropertyType = typeof(T),
                Provider = settings.Providers["LocalFileSettingsProvider"],
                SerializeAs = SettingsSerializeAs.Xml
            };
            p.Attributes.Add(typeof(UserScopedSettingAttribute), new UserScopedSettingAttribute());
            var v = new SettingsPropertyValue(p);
            settings.Properties.Add(p);
            settings.Reload();
        }
        settings[key] = value;
        settings.Save();
    }
}

You could use Qt which, in case you don't know, is C++ with a bunch of additional libraries and classes and whatnot. Qt has a very convenient QByteArray class which I'm quite sure would suit your needs.

http://qt-project.org/

I did this and it works great

<?php if ( has_post_thumbnail() ) { ?>
<a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>"><?php the_post_thumbnail(); ?></a>
<?php } ?>

I'd like to suggest another approach to the "Oups I forgot to write sudo while opening my file" issue:

Instead of receiving a permission denied, and having to type :w!!, I find it more elegant to have a conditional vim command that does sudo vim if file owner is root.

This is as easy to implement (there might even be more elegant implementations, I'm clearly not a bash-guru):

function vim(){
  OWNER=$(stat -c '%U' $1)
  if [[ "$OWNER" == "root" ]]; then
    sudo /usr/bin/vim $*;
  else
    /usr/bin/vim $*;
  fi
}

And it works really well.

This is a more bash-centered approach than a vim-one so not everybody might like it.

Of course:

• there are use cases where it will fail (when file owner is not root but requires sudo, but the function can be edited anyway)
• it doesn't make sense when using vim for reading-only a file (as far as I'm concerned, I use tail or cat for small files)

But I find this brings a much better dev user experience, which is something that IMHO tends to be forgotten when using bash. :-)

Deleting and Recreating a project with same name is tricky. If you try to follow above suggested steps and try to create a project with same name as the one you just deleted, you will run into error like

'C:/xxxxxx/pom.xml' already exists in VFS

Here is what I found would work.

1. Remove module
2. File -> Invalidate Cache (at this point the Intelli IDEA wants to restart)
3. Close project
4. Delete the folder form system explorer.
5. Now you can create a project with same name as before.

Convert Date to String using this function

public String convertDateToString(Date date, String format) {
        String dateStr = null;
        DateFormat df = new SimpleDateFormat(format);
        try {
            dateStr = df.format(date);
        } catch (Exception ex) {
            System.out.println(ex);
        }
        return dateStr;
    }

From Convert Date to String in Java . And convert string to date again

public Date convertStringToDate(String dateStr, String format) {
        Date date = null;
        DateFormat df = new SimpleDateFormat(format);
        try {
            date = df.parse(dateStr);
        } catch (Exception ex) {
            System.out.println(ex);
        }
        return date;
    }

UPDATE 2018 FOR JQUERY 3 AND LATER

I know this is an old question but none of the above solutions worked for me. Here is the solution that worked:

//I only created this function as I am making many ajax calls with different urls and appending the result to different divs
function makeAjaxCall(requestType, urlTo, resultAreaId){
        var jqxhr = $.ajax({
            type: requestType,
            url: urlTo
        });
        //this section is executed when the server responds with no error 
        jqxhr.done(function(){

        });
        //this section is executed when the server responds with error
        jqxhr.fail(function(){

        })
        //this section is always executed
        jqxhr.always(function(){
            console.log("getting header " + jqxhr.getResponseHeader('testHeader'));
        });
    }

:.,$d

This will delete all content from current line to end of the file. This is very useful when you're dealing with test vector generation or stripping.

I had a JSON dict as a string. The keys and values were unicode objects like in the following example:

myStringDict = "{u'key':u'value'}"

I could use the byteify function suggested above by converting the string to a dict object using ast.literal_eval(myStringDict).

Some addition to JoshRiver's answer according to my case;

var functionCallbacks = [];
    var functionLock = false;
    var getData = function (url, callback) {
                   if (functionLock) {
                        functionCallbacks.push(callback);
                   } else {
                       functionLock = true;
                       functionCallbacks.push(callback);
                        $.getJSON(url, function (data) {
                            while (functionCallbacks.length) {
                                var thisCallback = functionCallbacks.pop();
                                thisCallback(data);
                            }
                            functionLock = false;
                        });
                    }
                };

// Usage
getData("api/orders",function(data){
    barChart(data);
});
getData("api/orders",function(data){
  lineChart(data);
});

There will be just one api call and these two function will consume same result.

Just register an Eventhandler on keydown events and check the length of the input field on that function and write it into a separate element.

See the demo.

var maxchar = 160;
var i = document.getElementById("textinput");
var c = document.getElementById("count");
c.innerHTML = maxchar;

i.addEventListener("keydown",count);

function count(e){
    var len =  i.value.length;
    if (len >= maxchar){
       e.preventDefault();
    } else{
       c.innerHTML = maxchar - len-1;   
    }
}
?

You should check the length on your server too, because Javascript might be disabled or the user wants to do something nasty on purpose.

There are times when it's useful to implement an interface that will be returned from within the class, but the implementation of that interface should be completely hidden from the outside world.

As an example - prior to the addition of yield to C#, one way to implement enumerators was to put the implementation of the enumerator as a private class within a collection. This would provide easy access to the members of the collection, but the outside world would not need/see the details of how this is implemented.

You can also use button click event like this:

<asp:TemplateField>
    <ItemTemplate>
        <asp:Button ID="Button1" runat="server" Text="Button" 
                    OnClick="MyButtonClick" />
    </ItemTemplate>
</asp:TemplateField>

protected void MyButtonClick(object sender, System.EventArgs e)
{
    //Get the button that raised the event
    Button btn = (Button)sender;

    //Get the row that contains this button
    GridViewRow gvr = (GridViewRow)btn.NamingContainer;
} 

OR

You can do like this to get data:

 void CustomersGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
 {

    // If multiple ButtonField column fields are used, use the
    // CommandName property to determine which button was clicked.
    if(e.CommandName=="Select")
    {
      // Convert the row index stored in the CommandArgument
      // property to an Integer.
      int index = Convert.ToInt32(e.CommandArgument);    

      // Get the last name of the selected author from the appropriate
      // cell in the GridView control.
      GridViewRow selectedRow = CustomersGridView.Rows[index];
    }
}

and Button in gridview should have command like this and handle rowcommand event:

<asp:gridview id="CustomersGridView" 
        datasourceid="CustomersSqlDataSource" 
        autogeneratecolumns="false"
        onrowcommand="CustomersGridView_RowCommand"
        runat="server">

        <columns>
          <asp:buttonfield buttontype="Button" 
            commandname="Select"
            headertext="Select Customer" 
            text="Select"/>
        </columns>
  </asp:gridview>

Check full example on MSDN

This works for me

const Generic = <T> (value: T) => {
    return value;
} 

As I understand it, you want the server be able to send messages through from client 1 to client 2. You cannot directly connect two clients because one of the two ends of a WebSocket connection needs to be a server.

This is some pseudocodish JavaScript:

Client:

var websocket = new WebSocket("server address");

websocket.onmessage = function(str) {
  console.log("Someone sent: ", str);
};

// Tell the server this is client 1 (swap for client 2 of course)
websocket.send(JSON.stringify({
  id: "client1"
}));

// Tell the server we want to send something to the other client
websocket.send(JSON.stringify({
  to: "client2",
  data: "foo"
}));

Server:

var clients = {};

server.on("data", function(client, str) {
  var obj = JSON.parse(str);

  if("id" in obj) {
    // New client, add it to the id/client object
    clients[obj.id] = client;
  } else {
    // Send data to the client requested
    clients[obj.to].send(obj.data);
  }
});

To trim a list in place without creating copies of it, use del:

>>> t = [1, 2, 3, 4, 5]
>>> # delete elements starting from index 4 to the end
>>> del t[4:]
>>> t
[1, 2, 3, 4]
>>> # delete elements starting from index 5 to the end
>>> # but the list has only 4 elements -- no error
>>> del t[5:]
>>> t
[1, 2, 3, 4]
>>> 

All those answer are good, but it somehow confuses newbie like me as it does not clarify compile check and runtime check. Preprocessor are before compile time, but we should make it clearer

This blog article shows How to detect the iPhone simulator? clearly

Runtime

First of all, let’s shortly discuss. UIDevice provides you already information about the device

[[UIDevice currentDevice] model]

will return you “iPhone Simulator” or “iPhone” according to where the app is running.

Compile time

However what you want is to use compile time defines. Why? Because you compile your app strictly to be run either inside the Simulator or on the device. Apple makes a define called TARGET_IPHONE_SIMULATOR. So let’s look at the code :

#if TARGET_IPHONE_SIMULATOR

NSLog(@"Running in Simulator - no app store or giro");

#endif

<?php
function current_url()
{
    $url      = "http://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
    $validURL = str_replace("&", "&amp", $url);
    return $validURL;
}
//echo "page URL is : ".current_url();

$offer_url = current_url();

?>



<?php

if ($offer_url == "checking url name") {
?> <p> hi this is manip5595 </p>

<?php
}
?>

    d.update(params)
    parts[n]=urllib.urlencode(d)

add_url_param(url, lang='en') == "http://stackoverflow.com/search?q=question&lang=en"

I found that you can put the .col class on the image will do the trick - however this gives it extra padding along with any other attributes associated with the class such as float left, however these can be cancelled by say for example a no padding class as an addition.
