Programs & Examples On #Vibration

I struggled understanding how to do this on my first implementation - make sure you have the following:

1) Your device supports vibration (my Samsung tablet did not work so I kept re-checking the code - the original code worked perfectly on my CM Touchpad

2) You have declared above the application level in your AndroidManifest.xml file to give the code permission to run.

3) Have imported both of the following in to your MainActivity.java with the other imports: import android.content.Context; import android.os.Vibrator;

4) Call your vibration (discussed extensively in this thread already) - I did it in a separate function and call this in the code at other points - depending on what you want to use to call the vibration you may need an image (Android: long click on a button -> perform actions) or button listener, or a clickable object as defined in XML (Clickable image - android):

 public void vibrate(int duration)
 {
    Vibrator vibs = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
    vibs.vibrate(duration);    
 }

And if you're using Xamarin (monotouch) framework, simply call

SystemSound.Vibrate.PlayAlertSound()

The following should suffice:

[^ ]

If you want to expand that to anything but white-space (line breaks, tabs, spaces, hard spaces):

[^\s]

or

\S  # Note this is a CAPITAL 'S'!

I wanted to match a string that ends with ".*" For this I had to use the following:

"^.*\\.\\*$"

Kinda silly if you think about it :D Heres what it means. At the start of the string there can be any character zero or more times followed by a dot "." followed by a star (*) at the end of the string.

I hope this comes in handy for someone. Thanks for the backslash thing to Fabian.

<label>Mobile Number(*)</label>
<input id="txtMobile" ng-maxlength="10" maxlength="10" Validate-phone  required  name='strMobileNo' ng-model="formModel.strMobileNo" type="text"  placeholder="Enter Mobile Number">
<span style="color:red" ng-show="regForm.strMobileNo.$dirty && regForm.strMobileNo.$invalid"><span ng-show="regForm.strMobileNo.$error.required">Phone is required.</span>

the following code will help for phone number validation and the respected directive is

app.directive('validatePhone', function() {
var PHONE_REGEXP = /^[789]\d{9}$/;
  return {
    link: function(scope, elm) {
      elm.on("keyup",function(){
            var isMatchRegex = PHONE_REGEXP.test(elm.val());
            if( isMatchRegex&& elm.hasClass('warning') || elm.val() == ''){
              elm.removeClass('warning');
            }else if(isMatchRegex == false && !elm.hasClass('warning')){
              elm.addClass('warning');
            }
      });
    }
  }
});

If you look at the examples on the api page there is this: Example: Creates a different alias instead of jQuery to use in the rest of the script.

var j = jQuery.noConflict();
// Do something with jQuery
j("div p").hide();
// Do something with another library's $()
$("content").style.display = 'none';

Put the var j = jQuery.noConflict() after you bring in jquery and then bring in the conflicting scripts. You can then use the j in place of $ for all your jquery needs and use the $ for the other script.

I had problem with Eclipse (started as GUI, not from script) on Maverics that it did not take custom PATH. I tried all the methods mentioned above to no avail. Finally I found the simplest working answer based on hints from here:

1. Go to /Applications/eclipse/Eclipse.app/Contents folder

2. Edit Info.plist file with text editor (or XCode), add LSEnvironment dictionary for environment variable with full path. Note that it includes also /usr/bin etc:

   <dict>
     <key>LSEnvironment</key>
     <dict>
           <key>PATH</key>
           <string>/usr/bin:/bin:/usr/sbin:/sbin:/dev/android-ndk-r9b</string>
     </dict>
     <key>CFBundleDisplayName</key>
     <string>Eclipse</string>
     ...
   

3. Reload parameters for app with

   /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.fra??mework/Support/lsregister -v -f /Applications/eclipse/Eclipse.app
   

4. Restart Eclipse

Try this property

line-height:200%;

or

line-height:17px;

use the increase & decrease the volume

If you are using text-overflow:ellipsis, the browser will show the contents whatever possible within that container. But if you want to specifiy the number of letters before the dots or strip some contents and add dots, you can use the below function.

function add3Dots(string, limit)
{
  var dots = "...";
  if(string.length > limit)
  {
    // you can also use substr instead of substring
    string = string.substring(0,limit) + dots;
  }
 
    return string;
}

call like

add3Dots("Hello World",9);

outputs

Hello Wor...

See it in action here

function add3Dots(string, limit)
{
  var dots = "...";
  if(string.length > limit)
  {
    // you can also use substr instead of substring
    string = string.substring(0,limit) + dots;
  }

    return string;
}



console.log(add3Dots("Hello, how are you doing today?", 10));

-[NSString initWithData:encoding] will return nil if the specified encoding doesn't match the data's encoding.

Make sure your data is encoded in UTF-8 (or change NSUTF8StringEncoding to whatever encoding that's appropriate for the data).

As has already been mentioned there is the as yet not fully supported window.location.origin but instead of either using it or creating a new variable to use, I prefer to check for it and if it isn't set to set it.

For example;

if (!window.location.origin) {
  window.location.origin = window.location.protocol + "//" + window.location.hostname + (window.location.port ? ':' + window.location.port: '');
}

I actually wrote about this a few months back A fix for window.location.origin

Because lock is expensive, when you are using synchronized block you lock only if _instance == null, and after _instance finally initialized you'll never lock. But when you synchronize on method you lock unconditionally, even after the _instance is initialized. This is the idea behind double-checked locking optimization pattern http://en.wikipedia.org/wiki/Double-checked_locking.

Like others have already said, it's not immediately obvious what you're asking. I'm going to assume that you want to start a process and then perform another action when the process "is ready".

Of course, the "is ready" is the tricky bit. Depending on what you're needs are, you may find that simply waiting is sufficient. However, if you need a more robust solution, you can consider using a named Mutex to control the control flow between your two processes.

For example, in your main process, you might create a named mutex and start a thread or task which will wait. Then, you can start the 2nd process. When that process decides that "it is ready", it can open the named mutex (you have to use the same name, of course) and signal to the first process.

Try this:

par(adj = 0)
plot(1, 1, main = "Title")

or equivalent:

plot(1, 1, main = "Title", adj = 0)

adj = 0 produces left-justified text, 0.5 (the default) centered text and 1 right-justified text. Any value in [0, 1] is allowed.

However, the issue is that this will also change the position of the label of the x-axis and y-axis.

I just put the content in the question in a file called test.php and ran php test.php. (In the folder where the test.php is.)

$ php foo.php

After going through most of the solutions that are cited here, I still was getting the error.

The issue was case insensitive OS X. Checking out a directory that has two files with the same name, but different capitalization causes an issue. For example, ApproximationTest.java and Approximationtest.java should not be in the same directory. As soon as we get rid of one of the file, the issue goes away.

Loading the file from: {project}/src/main/webapp/WEB-INF/spring-dispatcher-servlet.xml

you refer to Android resources , which are already defined in Android system, with @android:id/.. while to access resources that you have defined/created in your project, you use @id/..

More Info

As per your clarifications in the chat, you said you have a problem like this :

If we use android:id="@id/layout_item_id" it doesn't work. Instead @+id/ works so what's the difference here? And that was my original question.

Well, it depends on the context, when you're using the XML attribute of android:id, then you're specifying a new id, and are instructing the parser (or call it the builder) to create a new entry in R.java, thus you have to include a + sign.

While in the other case, like android:layout_below="@id/myTextView" , you're referring to an id that has already been created, so parser links this to the already created id in R.java.

More Info Again

As you said in your chat, note that android:layout_below="@id/myTextView" won't recognize an element with id myTextViewif it is written after the element you're using it in.

If you're not worried about a couple minutes time to do so, a solution would be to rm -rf node_modules and npm install again to rebuild the local modules.

It is used in the stack unwiding tables, which you can see for instance in the assembly output of my answer to another question. As mentioned on that answer, its use is defined by the Itanium C++ ABI, where it is called the Personality Routine.

The reason it "works" by defining it as a global NULL void pointer is probably because nothing is throwing an exception. When something tries to throw an exception, then you will see it misbehave.

Of course, if nothing is using exceptions, you can disable them with -fno-exceptions (and if nothing is using RTTI, you can also add -fno-rtti). If you are using them, you have to (as other answers already noted) link with g++ instead of gcc, which will add -lstdc++ for you.

I still remember the first weeks of my programming courses and I totally understand how you feel. Here is the code that solves your problem. In order to learn from this answer, try to run it adding several 'print' in the loop, so you can see the progress of the variables.

import java.util.*;
import java.lang.*;

public class foo
{

   public static void main(String[] args)
   { 
      double[] alpha = new double[50];
      int count = 0;

      for (int i=0; i<50; i++)
      {
          // System.out.print("variable i = " + i + "\n");
          if (i < 25)
          {
                alpha[i] = i*i;
          }
          else {
                alpha[i] = 3*i;
          }

          if (count < 10)
          {
            System.out.print(alpha[i]+ " "); 
          }  
          else {
            System.out.print("\n"); 
            System.out.print(alpha[i]+ " "); 
            count = 0;
          }

          count++;
      }

      System.out.print("\n"); 

    }
}

You can loop the array with a for loop and the object properties with for-in loops.

for (var i=0; i<result.length; i++)
    for (var name in result[i]) {
        console.log("Item name: "+name);
        console.log("Source: "+result[i][name].sourceUuid);
        console.log("Target: "+result[i][name].targetUuid);
    }

Perhaps not in the context that you have it, but you could use

SELECT DISTINCT col1,
PERCENTILE_CONT(col2) WITHIN GROUP (ORDER BY col2) OVER (PARTITION BY col1),
PERCENTILE_CONT(col2) WITHIN GROUP (ORDER BY col2) OVER (PARTITION BY col1, col3),
FROM TableA

You would use this to return different levels of aggregation returned in a single row. The use case would be for when a single grouping would not suffice all of the aggregates needed.

Here is a link to a Visio Stencil and Template for UML 2.0.

Sure you can. Eg.

<?php
$newsXML = new SimpleXMLElement("<news></news>");
$newsXML->addAttribute('newsPagePrefix', 'value goes here');
$newsIntro = $newsXML->addChild('content');
$newsIntro->addAttribute('type', 'latest');
Header('Content-type: text/xml');
echo $newsXML->asXML();
?>

Output

<?xml version="1.0"?>
<news newsPagePrefix="value goes here">
    <content type="latest"/>
</news>

Have fun.

use the "maxlength" attribute as others have said.

if you need to put a max character length on a text AREA, you need to turn to Javascript. Take a look here: How to impose maxlength on textArea in HTML using JavaScript

Add "new":

var movies = _db.Movies.OrderBy( m => new { m.CategoryID, m.Name })

That works on my box. It does return something that can be used to sort. It returns an object with two values.

Similar, but different to sorting by a combined column, as follows.

var movies = _db.Movies.OrderBy( m => (m.CategoryID.ToString() + m.Name))

HTML:

<tr>
    <th>Language</th>
    <th>Skill Level</th>
    <th>&nbsp;</th>
</tr>

CSS:

tr, th {
    padding: 10px;
    text-align: center;
}

It may be possible to use C to write programs that behave robustly in such environments, but only if most forms of compiler optimization are disabled. Optimizing compilers are designed to replace many seemingly-redundant coding patterns with "more efficient" ones, and may have no clue that the reason the programmer is testing x==42 when the compiler knows there's no way x could possibly hold anything else is because the programmer wants to prevent the execution of certain code with x holding some other value--even in cases where the only way it could hold that value would be if the system received some kind of electrical glitch.

Declaring variables as volatile is often helpful, but may not be a panacea. Of particular importance, note that safe coding often requires that dangerous operations have hardware interlocks that require multiple steps to activate, and that code be written using the pattern:

... code that checks system state
if (system_state_favors_activation)
{
  prepare_for_activation();
  ... code that checks system state again
  if (system_state_is_valid)
  {
    if (system_state_favors_activation)
      trigger_activation();
  }
  else
    perform_safety_shutdown_and_restart();
}
cancel_preparations();

If a compiler translates the code in relatively literal fashion, and if all the checks for system state are repeated after the prepare_for_activation(), the system may be robust against almost any plausible single glitch event, even those which would arbitrarily corrupt the program counter and stack. If a glitch occurs just after a call to prepare_for_activation(), that would imply that activation would have been appropriate (since there's no other reason prepare_for_activation() would have been called before the glitch). If the glitch causes code to reach prepare_for_activation() inappropriately, but there are no subsequent glitch events, there would be no way for code to subsequently reach trigger_activation() without having passed through the validation check or calling cancel_preparations first [if the stack glitches, execution might proceed to a spot just before trigger_activation() after the context that called prepare_for_activation() returns, but the call to cancel_preparations() would have occurred between the calls to prepare_for_activation() and trigger_activation(), thus rendering the latter call harmless.

Such code may be safe in traditional C, but not with modern C compilers. Such compilers can be very dangerous in that sort of environment because aggressive they strive to only include code which will be relevant in situations that could come about via some well-defined mechanism and whose resulting consequences would also be well defined. Code whose purpose would be to detect and clean up after failures may, in some cases, end up making things worse. If the compiler determines that the attempted recovery would in some cases invoke undefined behavior, it may infer that the conditions that would necessitate such recovery in such cases cannot possibly occur, thus eliminating the code that would have checked for them.

The best answer for this would be something like this:

function addhttp($url, $scheme="http://" )
{
  return $url = empty(parse_url($url)['scheme']) ? $scheme . ltrim($url, '/') : $url;
}

The protocol flexible, so the same function can be used with ftp, https, etc.

I think style no. 111 (Japan) should work:

SELECT CONVERT(DATETIME, '2012-08-17', 111)

And if that doesn't work for some reason - you could always just strip out the dashes and then you have the totally reliable ISO-8601 format (YYYYMMDD) which works for any language and date format setting in SQL Server:

SELECT CAST(REPLACE('2012-08-17', '-', '') AS DATETIME)

You have to use HorizontalContentAlignment="Center" and! Width="Auto".

You can also check if your version is using MKL with:

import numpy
numpy.show_config()

Under "Settings -> Editor -> General -> Auto Import" there are several options regarding automatic imports. Only unambiguous imports may be added automatically; this is one of the options.

I was facing the same problem and the second method proposed in the accepted answer, as noted in the comments, can be problematic when dealing with foreign keys.

My workaround is to export the database to a sql file making sure that the INSERT statements include column names. I do it using DB Browser for SQLite which has an handy feature for that. After that you just have to edit the create table statement and insert the new column where you want it and recreate the db.

In *nix like systems is just something along the lines of

cat db.sql | sqlite3 database.db

I don't know how feasible this is with very big databases, but it worked in my case.

I did find any of these solutions met my requirements, so made my own version of node called node2exe that does this. It's available from https://github.com/areve/node2exe

After displaying the first 1000 records, you can page through them by clicking on the icon beside "Fetch rows:" in the header of the result grid.

Martijn's method as a prototype function:

String.prototype.escape = function() {
    var tagsToReplace = {
        '&': '&',
        '<': '&lt;',
        '>': '&gt;'
    };
    return this.replace(/[&<>]/g, function(tag) {
        return tagsToReplace[tag] || tag;
    });
};

var a = "<abc>";
var b = a.escape(); // "&lt;abc&gt;"

I was using python interpolation and forgot the ending s character:

a = dict(foo='bar')
print("What comes after foo? %(foo)" % a) # Should be %(foo)s

Watch those typos.

If you are just going to substitute it into a URL I suppose one field would do - so you can form a URL like

http://maps.google.co.uk/maps?q=12.345678,12.345678&z=6

but as it is two pieces of data I would store them in separate fields

There is no way to decrypt MD5. Well, there is, but no reasonable way to do it. That's kind of the point.

To check if someone is entering the correct password, you need to MD5 whatever the user entered, and see if it matches what you have in the database.

you can download the pdf file using fetch, and print it with print.js

                          fetch("url")
                            .then(function (response) {

                                response.blob().then(function (blob) {
                                    var reader = new FileReader();
                                    reader.onload = function () {

                                        //Remove the data:application/pdf;base64,
                                        printJS({
                                            printable: reader.result.substring(28),
                                            type: 'pdf',
                                            base64: true
                                        });
                                    };
                                    reader.readAsDataURL(blob);
                                })
                            });

This is old, but I put exports in my alias for connecting to the db:

alias schema_one.con="PGOPTIONS='--search_path=schema_one' psql -h host -U user -d database etc"

And for another schema:

alias schema_two.con="PGOPTIONS='--search_path=schema_two' psql -h host -U user -d database etc"

You can run a JAR file from the command line like this:

java -jar myJARFile.jar

On a branch I was able to do it like this (for the last 4 commits)

git checkout my_branch
git reset --soft HEAD~4
git commit
git push --force origin my_branch

put your CA & root certificate in /usr/share/ca-certificate or /usr/local/share/ca-certificate. Then

dpkg-reconfigure ca-certificates

or even reinstall ca-certificate package with apt-get.

After doing this your certificate is collected into system's DB: /etc/ssl/certs/ca-certificates.crt

Then everything should be fine.

Use the following command to get connected to your MySQL database

mysql -u USERNAME -h HOSTNAME -p

First, Latin-1 is the same as ISO-8859-1, so, the default was already OK for you. Right?

You successfully set the encoding to ISO-8859-1 with your command line parameter. You also set it programmatically to "Latin-1", but, that's not a recognized value of a file encoding for Java. See http://java.sun.com/javase/6/docs/technotes/guides/intl/encoding.doc.html

When you do that, looks like Charset resets to UTF-8, from looking at the source. That at least explains most of the behavior.

I don't know why OutputStreamWriter shows ISO8859_1. It delegates to closed-source sun.misc.* classes. I'm guessing it isn't quite dealing with encoding via the same mechanism, which is weird.

But of course you should always be specifying what encoding you mean in this code. I'd never rely on the platform default.

echo -e ' \t '

will echo 'space tab space newline' (-e means 'enable interpretation of backslash escapes'):

$ echo -e ' \t ' | hexdump -C
00000000  20 09 20 0a                                       | . .|

When all else fails in Cygwin...

Try running the dos2unix command on the file in question.

It might help when you see error messages like this:

-bash: '\r': command not found

Windows style newline characters can cause issues in Cygwin.

The dos2unix command modifies newline characters so they are Unix / Cygwin compatible.

CAUTION: the dos2unix command modifies files in place, so take precaution if necessary.

If you need to keep the original file, you should back it up first.

Note for Mac users: The dos2unix command does not exist on Mac OS X.

Check out this answer for a variety of solutions using different tools.

There is also a unix2dos command that does the reverse:

It modifies Unix newline characters so they're compatible with Windows tools.

If you open a file with Notepad and all the lines run together, try unix2dos filename.

For attributes whose type is an immutable value class that conforms to the NSCopying protocol, you almost always should specify copy in your @property declaration. Specifying retain is something you almost never want in such a situation.

Here's why you want to do that:

NSMutableString *someName = [NSMutableString stringWithString:@"Chris"];

Person *p = [[[Person alloc] init] autorelease];
p.name = someName;

[someName setString:@"Debajit"];

The current value of the Person.name property will be different depending on whether the property is declared retain or copy — it will be @"Debajit" if the property is marked retain, but @"Chris" if the property is marked copy.

Since in almost all cases you want to prevent mutating an object's attributes behind its back, you should mark the properties representing them copy. (And if you write the setter yourself instead of using @synthesize you should remember to actually use copy instead of retain in it.)

The corrected code is

import urllib.request
fhand = urllib.request.urlopen('http://data.pr4e.org/romeo.txt')
counts = dict()
for line in fhand: 
    words = line.decode().split() 
for word in words: 
    counts[word] = counts.get(word, 0) + 1 
print(counts) 

running the code above produces

{'Who': 1, 'is': 1, 'already': 1, 'sick': 1, 'and': 1, 'pale': 1, 'with': 1, 'grief': 1}

With LINQ:

List<string> l = new List<string> { "1", "2", "3" ,"4","5"};
List<string> l2 = l.Skip(1).Take(2).ToList();

If you need foreach, then no need for ToList:

foreach (string s in l.Skip(1).Take(2)){}

Advantage of LINQ is that if you want to just skip some leading element,you can :

List<string> l2 = l.Skip(1).ToList();
foreach (string s in l.Skip(1)){}

i.e. no need to take care of count/length, etc.

If you are using PHPMyAdmin You can be solved this issue by doing this:

CAUTION: Don't use this solution if you want to maintain existing records in your table.

Step 1: Select database export method to custom:

Step 2: Please make sure to check truncate table before insert in data creation options:

Now you are able to import this database successfully.

Posting data is a matter of sending a query string (just like the way you would send it with an URL after the ?) as the request body.

This requires Content-Type and Content-Length headers, so the receiving server knows how to interpret the incoming data. ^(*)

var http = require('http');

    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Length': Buffer.byteLength(data)
    }
};

var req = http.request(options, function(res) {
    res.setEncoding('utf8');
    res.on('data', function (chunk) {
        console.log("body: " + chunk);
    });
});

req.write(data);
req.end();

^(*) Sending data requires the Content-Type header to be set correctly, i.e. application/x-www-form-urlencoded for the traditional format that a standard HTML form would use.

It's easy to send JSON (application/json) in exactly the same manner; just JSON.stringify() the data beforehand.

URL-encoded data supports one level of structure (i.e. key and value). JSON is useful when it comes to exchanging data that has a nested structure.

The bottom line is: The server must be able to interpret the content type in question. It could be text/plain or anything else; there is no need to convert data if the receiving server understands it as it is.

Add a charset parameter (e.g. application/json; charset=Windows-1252) if your data is in an unusual character set, i.e. not UTF-8. This can be necessary if you read it from a file, for example.

CSS was designed to affect presentation, not behaviour.

You could use some JavaScript.

document.links[0].onclick = function(event) {
   event.preventDefault();
};

Thank you for posting the realWidth function above, it really helped me. Based on "realWidth" function above, I wrote, a CSS reset, (reason described below).

function getUnvisibleDimensions(obj) {
    if ($(obj).length == 0) {
        return false;
    }

    var clone = obj.clone();
    clone.css({
        visibility:'hidden',
        width : '',
        height: '',
        maxWidth : '',
        maxHeight: ''
    });
    $('body').append(clone);
    var width = clone.outerWidth(),
        height = clone.outerHeight();
    clone.remove();
    return {w:width, h:height};
}

"realWidth" gets the width of an existing tag. I tested this with some image tags. The problem was, when the image has given CSS dimension per width (or max-width), you will never get the real dimension of that image. Perhaps, the img has "max-width: 100%", the "realWidth" function clone it and append it to the body. If the original size of the image is bigger than the body, then you get the size of the body and not the real size of that image.

@parag's code works great. But while loading some large images you may fail. You should use;

imageView.setImageBitmap(getScaledBitmap(picturePath, 800, 800));

instead of;

imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

Here are my methods that you can use.

private Bitmap getScaledBitmap(String picturePath, int width, int height) {
    BitmapFactory.Options sizeOptions = new BitmapFactory.Options();
    sizeOptions.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(picturePath, sizeOptions);

    int inSampleSize = calculateInSampleSize(sizeOptions, width, height);

    sizeOptions.inJustDecodeBounds = false;
    sizeOptions.inSampleSize = inSampleSize;

    return BitmapFactory.decodeFile(picturePath, sizeOptions);
}

private int calculateInSampleSize(BitmapFactory.Options options, int reqWidth, int reqHeight) {
    // Raw height and width of image
    final int height = options.outHeight;
    final int width = options.outWidth;
    int inSampleSize = 1;

    if (height > reqHeight || width > reqWidth) {

        // Calculate ratios of height and width to requested height and
        // width
        final int heightRatio = Math.round((float) height / (float) reqHeight);
        final int widthRatio = Math.round((float) width / (float) reqWidth);

        // Choose the smallest ratio as inSampleSize value, this will
        // guarantee
        // a final image with both dimensions larger than or equal to the
        // requested height and width.
        inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;
    }

    return inSampleSize;
}

Make it work, in values-v21 styles or theme xml needs to use this attribute:

<item name="android:windowTranslucentStatus">true</item>

That make the magic!

Just select the code and

• on Windows do Ctrl + Alt + L

• on Linux do Ctrl + Windows Key + Alt + L

• on Mac do CMD + Option + L

You can either remove E_STRICT from error_reporting(), or you can simply make your method static, if you need to call it statically. As far as I know, there is no (strict) way to have a method that can be invoked both as static and non-static method. Also, which is more annoying, you cannot have two methods with the same name, one being static and the other non-static.

Simple thing I did after Someone said here to restart the VSCode and I did that, and now everything works fine.

For me it was because just when I was creating project I got an notification for updating my dart(or related) extension and for that I did it and boom as my project started, it just gave me around 30 errors which do scared but the simple FIX was to RESTART THE EDITOR.

I realize this is an old question, and the OP is talking about using custom gx that aren't necessary 'checkbox'-looking, but there is a fantastic resource for generating custom colored assets here: http://kobroor.pl/

Just give it the relevant details and it spits out graphics, complete with xml resources, that you can just drop right in.

I can't comment yet, but make sure you made all the checks in this quide: How to enable remote connections in SQL Server 2008? It should work fine if all steps are made.

Most of the time you can just npm update (or yarn upgrade) a module to get the latest non breaking changes (respecting the semver specified in your package.json) (<-- read that last part again).

npm update browser-sync
-------
yarn upgrade browser-sync

• Use npm|yarn outdated to see which modules have newer versions
• Use npm update|yarn upgrade (without a package name) to update all modules
• Include --save-dev|--dev if you want to save the newer version numbers to your package.json. (NOTE: as of npm v5.0 this is only necessary for devDependencies).

Major version upgrades:

In your case, it looks like you want the next major version (v2.x.x), which is likely to have breaking changes and you will need to update your app to accommodate those changes. You can install/save the latest 2.x.x by doing:

npm install browser-sync@2 --save-dev
-------
yarn add browser-sync@2 --dev

...or the latest 2.1.x by doing:

npm install [email protected] --save-dev
-------
yarn add [email protected] --dev

...or the latest and greatest by doing:

npm install browser-sync@latest --save-dev
-------
yarn add browser-sync@latest --dev

Note: the last one is no different than doing this:

npm uninstall browser-sync --save-dev
npm install browser-sync --save-dev
-------
yarn remove browser-sync --dev
yarn add browser-sync --dev

The --save-dev part is important. This will uninstall it, remove the value from your package.json, and then reinstall the latest version and save the new value to your package.json.

Best case for human logic to computer generated bytecode would be to utilize code like the following:

private double translateSlider(int sliderVal) {
  float retval = 1.0;

  switch (sliderVal) {
    case 1: retval = 0.9; break;
    case 2: retval = 0.8; break;
    case 3: retval = 0.7; break;
    case 4: retval = 0.6; break;
    case 0:
    default: break;
  }
  return retval;
}

Thus eliminating multiple exits from the method and utilizing the language logically. (ie while sliderVal is an integer range of 1-4 change float value else if sliderVal is 0 and all other values, retval stays the same float value of 1.0)

However something like this with each integer value of sliderVal being (n-(n/10)) one really could just do a lambda and get a faster results:

private double translateSlider = (int sliderVal) -> (1.0-(siderVal/10));

Edit: A modulus of 4 may be in order to keep logic (ie (n-(n/10))%4))

If you're having some problem about "error compiler of class file", it's possible to resolve this by changing the project's JRE to its correspondent through Eclipse.

1. Build path
2. Configure build path
3. Change library to correspondent of table that friend shows last.
4. Create "jar file" and compile and execute.

I did that and it worked.

in a single try catch block you can do all the thing the best practice is to catch the error in different catch block if you want them to show with their own message for particular errors.

When you're running npm install in the project's root, it installs all of the npm dependencies into the project's node_modules directory.

If you take a look at the project's node_modules directory, you should see a directory called http-server, which holds the http-server package, and a .bin folder, which holds the executable binaries from the installed dependencies. The .bin directory should have the http-server binary (or a link to it).

So in your case, you should be able to start the http-server by running the following from your project's root directory (instead of npm start):

./node_modules/.bin/http-server -a localhost -p 8000 -c-1

This should have the same effect as running npm start.

If you're running a Bash shell, you can simplify this by adding the ./node_modules/.bin folder to your $PATH environment variable:

export PATH=./node_modules/.bin:$PATH

This will put this folder on your path, and you should be able to simply run

http-server -a localhost -p 8000 -c-1

Using gson it is much simpler. Use following code snippet:

 // create a new Gson instance
 Gson gson = new Gson();
 // convert your list to json
 String jsonCartList = gson.toJson(cartList);
 // print your generated json
 System.out.println("jsonCartList: " + jsonCartList);

Converting back from JSON string to your Java object

 // Converts JSON string into a List of Product object
 Type type = new TypeToken<List<Product>>(){}.getType();
 List<Product> prodList = gson.fromJson(jsonCartList, type);

 // print your List<Product>
 System.out.println("prodList: " + prodList);

They're equivalent. The access is the same.

The import is just a convention to save you from having to type the fully-resolved class name each time. You can write all your Java without using import, as long as you're a fast touch typer.

But there's no difference in efficiency or class loading.

in my case i did following steps and it worked:

1. In Xampp control panel click on "Services" button from the right side toolbar

2. Then find "MySQL" from the services List

3. Click on it and from the left side of the panel click on "stop"

4. Turn back in Xampp control panel and click on start.

Alternative method: In Eclipse 3.6, under "Line Wrapping" then "General Settings" there is an option to "Never join already wrapped lines." This means the formatter will wrap long lines but not undo any wrapping you already have.

   if(selection == 'other')
   {

      $('#otherType').hide();
   } 

});

I think this other Stack Overflow question could help:

How to get JDK 1.5 on Mac OS X

It basically says that if you need to compile or execute a Java application with an older version of the JDK (for example 1.4 or 1.5), you can do it using the 1.6 because it is backwards compatible. To do it so you will need to add the parameter -source 1.5 and/or -target 1.5 in the javac options or in your IDE.

I'm a recent student but I BELIEVE the original example with int[] is iterating over the primitives array, but not by using an Iterator object. It merely has the same (similar) syntax with different contents,

for (primitive_type : array) { }

for (object_type : iterableObject) { }

Arrays.asList() APPARENTLY just applies List methods to an object array that it's given - but for any other kind of object, including a primitive array, iterator().next() APPARENTLY just hands you the reference to the original object, treating it as a list with one element. Can we see source code for this? Wouldn't you prefer an exception? Never mind. I guess (that's GUESS) that it's like (or it IS) a singleton Collection. So here asList() is irrelevant to the case with a primitives array, but confusing. I don't KNOW I'm right, but I wrote a program that says that I am.

Thus this example (where basically asList() doesn't do what you thought it would, and therefore is not something that you'd actually use this way) - I hope the code works better than my marking-as-code, and, hey, look at that last line:

// Java(TM) SE Runtime Environment (build 1.6.0_19-b04)

import java.util.*;

public class Page0434Ex00Ver07 {
public static void main(String[] args) {
    int[] ii = new int[4];
    ii[0] = 2;
    ii[1] = 3;
    ii[2] = 5;
    ii[3] = 7;

    Arrays.asList(ii);

    Iterator ai = Arrays.asList(ii).iterator();

    int[] i2 = (int[]) ai.next();

    for (int i : i2) {
        System.out.println(i);
    }

    System.out.println(Arrays.asList(12345678).iterator().next());
}
}

You can keep your CONTACT parameter with the following approach:

using (var stream = new MemoryStream())
{
    var context = (HttpContextBase)Request.Properties["MS_HttpContext"];
    context.Request.InputStream.Seek(0, SeekOrigin.Begin);
    context.Request.InputStream.CopyTo(stream);
    string requestBody = Encoding.UTF8.GetString(stream.ToArray());
}

Returned for me the json representation of my parameter object, so I could use it for exception handling and logging.

Found as accepted answer here

It sounds like you want something like this:

$array = array(
    'First',
    'Second',
    'Third',
    'Last'
);

foreach($array as $key => $value)
{
    if(end($array) === $value)
    {
       echo "last index!" . $value;
    }
}

If you need more control (perhaps you need to state the table name) you can also do the following:

Model.joins(:another_model_table_name)
  .where('another_model_table_name.id IN (?)', your_id_array)

In my case I was missing "e" on the word "email" as Chad stated above but I see its not the case with you. Please hit the following command to see if everything is pulling as expected.

git config -l

In your MakeFile or CMakeLists.txt you can set CMAKE_CXX_FLAGS as below:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -I/path/to/your/folder")

Your dataframe has four columns like so df[,c(1,2,3,4)]. Note the first comma means keep all the rows, and the 1,2,3,4 refers to the columns.

To change the order as in the above question do df2[,c(1,3,2,4)]

If you want to output this file as a csv, do write.csv(df2, file="somedf.csv")

Combining the answer by "Pushcode" and the one using the seed for the random generator. I needed it to create a serie of pseudo-readable 'words'.

private int RandomNumber(int min, int max, int seed=0)
{
    Random random = new Random((int)DateTime.Now.Ticks + seed);
    return random.Next(min, max);
}

If one want to attach a process, this process must have the same owner. The root is able to attach to any process.

I got this working : -

$.get('api.php', 'client=mikescafe', function(data) {
...
});

It sends via get the string ?client=mikescafe then collect this variable in api.php, and use it in your mysql statement.

If you don't want to use jQuery mobile as like me. You can use Hammer.js

It's mostly like jQuery Mobile without unnecessary code.

$(document).ready(function() {
  Hammer(myCarousel).on("swipeleft", function(){
    $(this).carousel('next');
  });
  Hammer(myCarousel).on("swiperight", function(){
    $(this).carousel('prev');
  });
});

If you mean with "Web Service" something accessed by other Programms SimpleXMLRPCServer might be right for you. It is included with every Python install since Version 2.2.

For Simple human accessible things I usually use Pythons SimpleHTTPServer which also comes with every install. Obviously you also could access SimpleHTTPServer by client programs.

Here's a bit more detail to expand on Hooked's answer. When I first read that answer, I missed the instruction to call clf() instead of creating a new figure. clf() on its own doesn't help if you then go and create another figure.

Here's a trivial example that causes the warning:

from matplotlib import pyplot as plt, patches
import os


def main():
    path = 'figures'
    for i in range(21):
        _fig, ax = plt.subplots()
        x = range(3*i)
        y = [n*n for n in x]
        ax.add_patch(patches.Rectangle(xy=(i, 1), width=i, height=10))
        plt.step(x, y, linewidth=2, where='mid')
        figname = 'fig_{}.png'.format(i)
        dest = os.path.join(path, figname)
        plt.savefig(dest)  # write image to file
        plt.clf()
    print('Done.')

main()

To avoid the warning, I have to pull the call to subplots() outside the loop. In order to keep seeing the rectangles, I need to switch clf() to cla(). That clears the axis without removing the axis itself.

from matplotlib import pyplot as plt, patches
import os


def main():
    path = 'figures'
    _fig, ax = plt.subplots()
    for i in range(21):
        x = range(3*i)
        y = [n*n for n in x]
        ax.add_patch(patches.Rectangle(xy=(i, 1), width=i, height=10))
        plt.step(x, y, linewidth=2, where='mid')
        figname = 'fig_{}.png'.format(i)
        dest = os.path.join(path, figname)
        plt.savefig(dest)  # write image to file
        plt.cla()
    print('Done.')

main()

If you're generating plots in batches, you might have to use both cla() and close(). I ran into a problem where a batch could have more than 20 plots without complaining, but it would complain after 20 batches. I fixed that by using cla() after each plot, and close() after each batch.

from matplotlib import pyplot as plt, patches
import os


def main():
    for i in range(21):
        print('Batch {}'.format(i))
        make_plots('figures')
    print('Done.')


def make_plots(path):
    fig, ax = plt.subplots()
    for i in range(21):
        x = range(3 * i)
        y = [n * n for n in x]
        ax.add_patch(patches.Rectangle(xy=(i, 1), width=i, height=10))
        plt.step(x, y, linewidth=2, where='mid')
        figname = 'fig_{}.png'.format(i)
        dest = os.path.join(path, figname)
        plt.savefig(dest)  # write image to file
        plt.cla()
    plt.close(fig)


main()

I measured the performance to see if it was worth reusing the figure within a batch, and this little sample program slowed from 41s to 49s (20% slower) when I just called close() after every plot.

if ($done)
{
    header("Location: /url/to/the/other/page");
    exit;
}

I've tried the solutions in this thread and the ones here, but simply calling setExtendedState(getExtendedState()|Frame.MAXIMIZED_BOTH); right after calling setVisible(true); apparently does not work for my environment (Windows 10, JDK 1.8, my taskbar is on the right side of my screen). Doing it this way still leaves a tiny space on the left, right and bottom .

What did work for me however, is calling setExtendedState(... when the window is activated, like so:

public class SomeFrame extends JFrame {

    public SomeFrame() {
        // ...
        setVisible(true);
        setResizable(true);
        // if you are calling setSize() for fallback size, do that here
        addWindowListener (
            new WindowAdapter() {
                private boolean shown = false;
                @Override
                public void windowActivated(WindowEvent we) {
                    if(shown) return;
                    shown = true;
                    setExtendedState(getExtendedState()|JFrame.MAXIMIZED_BOTH);
                }
            }
        );
    }
}

You need to convert your script to a shell function:

#!/bin/bash
#
# this script should not be run directly,
# instead you need to source it from your .bashrc,
# by adding this line:
#   . ~/bin/myprog.sh
#

function myprog() {
  A=$1
  B=$2
  echo "aaa ${A} bbb ${B} ccc"
  cd /proc
}

The reason is that each process has its own current directory, and when you execute a program from the shell it is run in a new process. The standard "cd", "pushd" and "popd" are builtin to the shell interpreter so that they affect the shell process.

By making your program a shell function, you are adding your own in-process command and then any directory change gets reflected in the shell process.

All modules in Python have to have a certain directory structure. You can find details here.

Create an empty file called __init__.py under the model directory, such that your directory structure would look something like that:

.
+-- project
    +-- src
        +-- hello-world.py
        +-- model
            +-- __init__.py
            +-- order.py

Also in your hello-world.py file change the import statement to the following:

from model.order import SellOrder

That should fix it

P.S.: If you are placing your model directory in some other location (not in the same directory branch), you will have to modify the python path using sys.path.

The two calls have different meanings that have nothing to do with performance; the fact that it speeds up the execution time is (or might be) just a side effect. You should understand what each of them does and not blindly include them in every program because they look like an optimization.

ios_base::sync_with_stdio(false);

This disables the synchronization between the C and C++ standard streams. By default, all standard streams are synchronized, which in practice allows you to mix C- and C++-style I/O and get sensible and expected results. If you disable the synchronization, then C++ streams are allowed to have their own independent buffers, which makes mixing C- and C++-style I/O an adventure.

Also keep in mind that synchronized C++ streams are thread-safe (output from different threads may interleave, but you get no data races).

cin.tie(NULL);

This unties cin from cout. Tied streams ensure that one stream is flushed automatically before each I/O operation on the other stream.

By default cin is tied to cout to ensure a sensible user interaction. For example:

std::cout << "Enter name:";
std::cin >> name;

If cin and cout are tied, you can expect the output to be flushed (i.e., visible on the console) before the program prompts input from the user. If you untie the streams, the program might block waiting for the user to enter their name but the "Enter name" message is not yet visible (because cout is buffered by default, output is flushed/displayed on the console only on demand or when the buffer is full).

So if you untie cin from cout, you must make sure to flush cout manually every time you want to display something before expecting input on cin.

In conclusion, know what each of them does, understand the consequences, and then decide if you really want or need the possible side effect of speed improvement.

here is the code

    import React, { Component } from 'react';
    import logo from './logo.svg';
    import './image.css';
    import Dropdown from 'react-dropdown';
    import axios from 'axios';

    let obj = {};

    class App extends Component {
      constructor(){
        super();
        this.state = {
          selectedFiles: []
        }
        this.fileUploadHandler = this.fileUploadHandler.bind(this);
      }

      fileUploadHandler(file){
        let selectedFiles_ = this.state.selectedFiles;
        selectedFiles_.push(file);
        this.setState({selectedFiles: selectedFiles_});
      }

      render() {
        let Images = this.state.selectedFiles.map(image => {
          <div className = "image_parent">

              <img src={require(image.src)}
              />
          </div>
        });

        return (
            <div className="image-upload images_main">

            <input type="file" onClick={this.fileUploadHandler}/>
            {Images}

            </div>
        );
      }
    }

    export default App;

If you need only display the trimmed value then I'd suggest against manipulating the original string and using a filter instead.

app.filter('trim', function () {
    return function(value) {
        if(!angular.isString(value)) {
            return value;
        }  
        return value.replace(/^\s+|\s+$/g, ''); // you could use .trim, but it's not going to work in IE<9
    };
});

And then

<span>{{ foo | trim }}</span>

Use the Stringify.Library nuget package

//Default delimiter is ,
var split = new StringConverter().ConvertTo<List<string>>(names);

//You can also have your custom delimiter for e.g. ;
var split = new StringConverter().ConvertTo<List<string>>(names, new ConverterOptions { Delimiter = ';' });

Use Arrays class to do this

Arrays.sort(TYPES);
int index = Arrays.binarySearch(TYPES, "Sedan");

make the image float: left; and the text float: right;

Take a look at this fiddle I used a picture online but you can just swap it out for your picture.

def magic(number):
    return int(''.join(str(i) for i in number))

Declarative programming is when you say what you want, and imperative language is when you say how to get what you want.

A simple example in Python:

# Declarative
small_nums = [x for x in range(20) if x < 5]

# Imperative
small_nums = []
for i in range(20):
    if i < 5:
        small_nums.append(i)

The first example is declarative because we do not specify any "implementation details" of building the list.

To tie in a C# example, generally, using LINQ results in a declarative style, because you aren't saying how to obtain what you want; you are only saying what you want. You could say the same about SQL.

One benefit of declarative programming is that it allows the compiler to make decisions that might result in better code than what you might make by hand. Running with the SQL example, if you had a query like

SELECT score FROM games WHERE id < 100;

the SQL "compiler" can "optimize" this query because it knows that id is an indexed field -- or maybe it isn't indexed, in which case it will have to iterate over the entire data set anyway. Or maybe the SQL engine knows that this is the perfect time to utilize all 8 cores for a speedy parallel search. You, as a programmer, aren't concerned with any of those conditions, and you don't have to write your code to handle any special case in that way.

There are two useful tools which will generate Java code (rough but good enough) from an unknown APK file.

1. Download dex2jar tool from dex2jar.

2. Use the tool to convert the APK file to JAR:

   $ d2j-dex2jar.bat demo.apk
   dex2jar demo.apk -> ./demo-dex2jar.jar
   

3. Once the JAR file is generated, use JD-GUI to open the JAR file. You will see the Java files.

The output will be similar to:

I have fixed this problem when calling a MVC3 Controller. I added:

Response.AddHeader("Access-Control-Allow-Origin", "*"); 

before my

return Json(model, JsonRequestBehavior.AllowGet);

And also my $.ajax was complaining that it does not accept Content-type header in my ajax call, so I commented it out as I know its JSON being passed to the Action.

Hope that helps.

I ran into this error when I had a .jsx and .scss file in the same directory with the same root name.

So, for example, if you have Component.jsx and Component.scss in the same folder and you try to do this:

import Component from ./Component

Webpack apparently gets confused and, at least in my case, tries to import the scss file when I really want the .jsx file.

I was able to fix it by renaming the .scss file and avoiding the ambiguity. I could have also explicitly imported Component.jsx

You don't need to do anything, the Model Binding will pass null to property without any problem.

If you're trying to load a DataTable, then leverage the SqlDataAdapter instead:

DataTable dt = new DataTable();

using (SqlConnection c = new SqlConnection(cString))
using (SqlDataAdapter sda = new SqlDataAdapter(sql, c))
{
    sda.SelectCommand.CommandType = CommandType.StoredProcedure;
    sda.SelectCommand.Parameters.AddWithValue("@parm1", val1);
    ...

    sda.Fill(dt);
}

You don't even need to define the columns. Just create the DataTable and Fill it.

Here, cString is your connection string and sql is the stored procedure command.

Prefer EntityManagerFactory and EntityManager. They are defined by the JPA standard.

SessionFactory and Session are hibernate-specific. The EntityManager invokes the hibernate session under the hood. And if you need some specific features that are not available in the EntityManager, you can obtain the session by calling:

Session session = entityManager.unwrap(Session.class);

From my notes:

http://maps.google.com/maps?q=37.4185N+122.08774W+(label)&ll=37.419731,-122.088715&spn=0.004250,0.011579&t=h&iwloc=A&hl=en

Which parses like this:

    q=latN+lonW+(label)     location of teardrop

    t=k             keyhole (satelite map)
    t=h             hybrid

    ll=lat,-lon     center of map
    spn=w.w,h.h     span of map, degrees

iwloc has something to do with the info window. hl is obviously language.

I had this problem, this worked for me:

Install the postgresql-devel package, this will solve the issue of pg_config missing.

sudo apt-get install libpq-dev

In case you want to use sorted() function: sorted(list1, key=int)

It returns a new sorted list.

Also, we can assign the Value to the Control in Designer Class (i.e. FormName.Designer.cs).

DateTimePicker1.Value = DateTime.Now;

This way you always get Current Date...

The system stored procedure sp_help will give you the information. Execute the following statement:

execute sp_help table_name

Make the file accessible to the Authenticated Users group. Right click your virtual directory and give the group read/write access to Authenticated Users.

I faced issue on windows 10 machine.

There are 2 steps you need to perform,

1. Add the custom domains addon and add the domain your going to use, eg www.mywebsite.com to your application
2. Go to your domain registrar control panel and set www.mywebsite.com to be a CNAME entry to yourapp.herokuapp.com assuming you are using the CEDAR stack.
3. There is a third step if you want to use a naked domain, eg mywebsite.com when you would have to add the IP addresses of the Heroku load balancers to your DNS for mywebsite.com

You can read more about this at http://devcenter.heroku.com/articles/custom-domains

At a guess you've missed out the first step perhaps?

UPDATE: Following the announcement of Bamboo's EOL proxy.heroku.com being retired (September 2014) for Bamboo applications so these should also now use the yourapp.herokuapp.com mapping now as well.

In the fragment where you would like to handle your back button you should attach stuff to your view in the oncreateview

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.second_fragment, container, false);
    v.setOnKeyListener(pressed);
    return v;
}



@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
    // TODO Auto-generated method stub
    if( keyCode == KeyEvent.KEYCODE_BACK ){
            // back to previous fragment by tag
            myfragmentclass fragment = (myfragmentclass) getActivity().getSupportFragmentManager().findFragmentByTag(TAG);
            if(fragment != null){
                (getActivity().getSupportFragmentManager().beginTransaction()).replace(R.id.cf_g1_mainframe_fm, fragment).commit();

When using git you can incorporate the newest facebook-android-sdk with ease.

• Add facebook-android-sdk as submodule: git submodule add https://github.com/facebook/facebook-android-sdk.git
• Add sdk as gradle project: edit settings.gradle and add line: include ':facebook-android-sdk:facebook'
• Add sdk as dependency to module: edit build.gradle and add within dependencies block: compile project(':facebook-android-sdk:facebook')

Add an input id to the element and do something like that:

document.getElementById('inputId').value.split(/[\\$]/).pop()

Jano's answer is the easiest way to find it.. another way would be if you click on the scheme drop down bar -> edit scheme -> arguments tab and then add NSZombieEnabled in the Environment Variables column and YES in the value column...

I realize this question is asking about how to encode an associative array to a pretty-formatted JSON string, so this doesn't directly answer the question, but if you have a string that is already in JSON format, you can make it pretty simply by decoding and re-encoding it (requires PHP >= 5.4):

$json = json_encode(json_decode($json), JSON_PRETTY_PRINT);

Example:

header('Content-Type: application/json');
$json_ugly = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
$json_pretty = json_encode(json_decode($json_ugly), JSON_PRETTY_PRINT);
echo $json_pretty;

This outputs:

{
    "a": 1,
    "b": 2,
    "c": 3,
    "d": 4,
    "e": 5
}

You have two options:

You can either put an anchor in your document as follows:

<a name="ref"></a>

Or else you give an id to a any HTML element:

<h1 id="ref">Heading</h1>

Then simply append the hash #ref to the URL of your link to jump to the desired reference. Example:

<a href="document.html#ref">Jump to ref in document.html</a>

There is no built-in function in Javascript to perform this search.

If you are using jQuery you could do a jQuery.inArray(element,array).

Named pipes in a unix/linux context can be used to make two different shells to communicate since a shell just can't share anything with another.

Furthermore, one script instantiated twice in the same shell can't share anything through the two instances. I found a use for named pipes when coding a daemon that contains the start() and stop() function, and I wanted to use the same script to perform the two actions.

Without named pipes (or any kind of semaphore) starting the script in the background is not a problem. The thing is when it finishes you just can't access the instance in background.

So when you want to send him the stop command you just can't: running the same script without named pipes and calling the stop() function won't do anything since you are actually running another instance.

The solution was to implement two pipes, one READ and the other WRITE when you start the daemon. Then make him, among its other tasks, listen to the READ pipe. Then the Stop() function contains a command that will write a message in the pipe, that will be handled by the background running script that will perform an exit 0. This way our second instance of the same script has only on task to do: tell the first instance to stop.

This way one and only one script can start and stop itself.

Of course you have different ways to do it by triggering the stop via a touch for example. But this one is nice and interesting to code.

SqlConnection con = new SqlConnection(@"Some Connection String");//connection object
SqlDataAdapter da = new SqlDataAdapter("ParaEmp_Select",con);//SqlDataAdapter class object
da.SelectCommand.CommandType = CommandType.StoredProcedure; //command sype
da.SelectCommand.Parameters.Add("@Contactid", SqlDbType.Int).Value = 123; //pass perametter
DataTable dt = new DataTable();  //dataset class object
da.Fill(dt); //call the stored producer

I just wanted something really basic to move some files out of the main folder, like user2889485's reply, but his specific answer didnt work for me. I didnt care if they were in the same package or not.

My GOPATH workspace is c:\work\go and under that I have

/src/pg/main.go      (package main)
/src/pg/dbtypes.go   (pakage dbtypes)

in main.go I import "/pg/dbtypes"

If you are dealing with a table and one of the dates happens to be null, you can code it like this:

  @{
     if (Model.SomeCollection[i].date_due == null)
       {
         <td><input type='date' id="@("dd" + i)" name="dd" /></td>
       }
       else
       {
         <td><input type='date' value="@Model.SomeCollection[i].date_due.Value.ToString("yyyy-MM-dd")" id="@("dd" + i)" name="dd" /></td>
       }
   }

Try adding these params to your docker yml file

restart: "no"
  restart: always
  restart: on-failure
  restart: unless-stopped
  environment:
    POSTGRES_DB: "db_name"
    POSTGRES_HOST_AUTH_METHOD: "trust"

Final file should look something like this

postgres:
  restart: "no"
  restart: always
  restart: on-failure
  restart: unless-stopped
  image: postgres:latest
  volumes:
    - /data/postgresql:/var/lib/postgresql
  ports:
    - "5432:5432"
  environment:
    POSTGRES_DB: "db_name"
    POSTGRES_HOST_AUTH_METHOD: "trust"

You can use the following code. It is similar to existing functions except that you can force special character count:

function random_string() {
    // 8 characters: 7 lower-case alphabets and 1 digit
    $character_sets = [
        ["count" => 7, "characters" => "abcdefghijklmnopqrstuvwxyz"],
        ["count" => 1, "characters" => "0123456789"]
    ];
    $temp_array = array();
    foreach ($character_sets as $character_set) {
        for ($i = 0; $i < $character_set["count"]; $i++) {
            $random = random_int(0, strlen($character_set["characters"]) - 1);
            $temp_array[] = $character_set["characters"][$random];
        }
    }
    shuffle($temp_array);
    return implode("", $temp_array);
}

From sun docs:

\s A whitespace character: [ \t\n\x0B\f\r]

The simplest way is to use it with regex.

If you pass in the list variable as a quoted string, you can reach it from within the function like:

push <- function(l, x) {
  assign(l, append(eval(as.name(l)), x), envir=parent.frame())
}

so:

> a <- list(1,2)
> a
[[1]]
[1] 1

[[2]]
[1] 2

> push("a", 3)
> a
[[1]]
[1] 1

[[2]]
[1] 2

[[3]]
[1] 3

> 

or for extra credit:

> v <- vector()
> push("v", 1)
> v
[1] 1
> push("v", 2)
> v
[1] 1 2
> 

A very simple answer if you say you don't care which address is used.

SELECT
    CName, MIN(AddressLine)
FROM
    MyTable
GROUP BY
    CName

If you want the first according to, say, an "inserted" column then it's a different query

SELECT
    M.CName, M.AddressLine,
FROM
    (
    SELECT
        CName, MIN(Inserted) AS First
    FROM
        MyTable
    GROUP BY
        CName
    ) foo
    JOIN
    MyTable M ON foo.CName = M.CName AND foo.First = M.Inserted

To sync the git repo with the submodule's head, in case that is really what you want, I found that removing the submodule and then readding it avoids the tinkering with the history. Unfortunately removing a submodule requires hacking rather than being a single git command, but doable.

Steps I followed to remove the submodule, inspired by https://gist.github.com/kyleturner/1563153:

1. Run git rm --cached
2. Delete the relevant lines from the .gitmodules file.
3. Delete the relevant section from .git/config.
4. Delete the now untracked submodule files.
5. Remove directory .git/modules/

Again, this can be useful if all you want is to point at the submodule's head again, and you haven't complicated things by needing to keep the local copy of the submodule intact. It assumes you have the submodule "right" as its own repo, wherever the origin of it is, and you just want to get back to properly including it as a submodule.

Note: always make a full copy of your project before engaging in these kinds of manipulation or any git command beyond simple commit or push. I'd advise that with all other answers as well, and as a general git guideline.

F# is not yet-another-programming-language if you are comparing it to C#, C++, VB. C#, C, VB are all imperative or procedural programming languages. F# is a functional programming language.

Two main benefits of functional programming languages (compared to imperative languages) are 1. that they don't have side-effects. This makes mathematical reasoning about properties of your program a lot easier. 2. that functions are first class citizens. You can pass functions as parameters to another functions just as easily as you can other values.

Both imperative and functional programming languages have their uses. Although I have not done any serious work in F# yet, we are currently implementing a scheduling component in one of our products based on C# and are going to do an experiment by coding the same scheduler in F# as well to see if the correctness of the implementation can be validated more easily than with the C# equivalent.

I have developed pure XML based word files in the past. I used .NET, but the language should not matter since it's truely XML. It was not the easiest thing to do (had a project that required it a couple years ago.) These do only work in Word 2007 or above - but all you need is Microsoft's white paper that describe what each tag does. You can accomplish all you want with the tags the same way as if you were using Word (of course a little more painful initially.)

i have this error using datatables.net

i fixed changing the default ajax Get to POST in te properties of the DataTable()

"ajax": {
        "url": "../ControllerName/MethodJson",
        "type": "POST"
    },

JSONP is JSON with padding. That is, you put a string at the beginning and a pair of parentheses around it. For example:

//JSON
{"name":"stackoverflow","id":5}
//JSONP
func({"name":"stackoverflow","id":5});

The result is that you can load the JSON as a script file. If you previously set up a function called func, then that function will be called with one argument, which is the JSON data, when the script file is done loading. This is usually used to allow for cross-site AJAX with JSON data. If you know that example.com is serving JSON files that look like the JSONP example given above, then you can use code like this to retrieve it, even if you are not on the example.com domain:

function func(json){
  alert(json.name);
}
var elm = document.createElement("script");
elm.setAttribute("type", "text/javascript");
elm.src = "http://example.com/jsonp";
document.body.appendChild(elm);

Why not use index or rindex?

You have to change the format of the date string you are supplying in order to be able to insert it using the STRFTIME function. Reason being, there is no option for a month abbreviation:

%d  day of month: 00
%f  fractional seconds: SS.SSS
%H  hour: 00-24
%j  day of year: 001-366
%J  Julian day number
%m  month: 01-12
%M  minute: 00-59
%s  seconds since 1970-01-01
%S  seconds: 00-59
%w  day of week 0-6 with sunday==0
%W  week of year: 00-53
%Y  year: 0000-9999
%%  % 

The alternative is to format the date/time into an already accepted format:

1. YYYY-MM-DD
2. YYYY-MM-DD HH:MM
3. YYYY-MM-DD HH:MM:SS
4. YYYY-MM-DD HH:MM:SS.SSS
5. YYYY-MM-DDTHH:MM
6. YYYY-MM-DDTHH:MM:SS
7. YYYY-MM-DDTHH:MM:SS.SSS
8. HH:MM
9. HH:MM:SS
10. HH:MM:SS.SSS
11. now

If your rollback segment/undo segment can accomodate the size of the transaction then option 2 is better. Option 1 is useful if you do not have the rollback capacity needed and have to break the large insert into smaller commits so you don't get rollback/undo segment too small errors.

1. Go to working directory where you project folder (cloned folder) is placed.
2. Now delete the folder.
3. in windows just right click and do delete.
4. in command line use rm -r "folder name"
5. this worked for me

>>> average =  [1,3,2,1,1,0,24,23,7,2,727,2,7,68,7,83,2]
>>> matches = [i for i in range(0,len(average)) if average[i]<2 or average[i]>4]
>>> matches
[0, 3, 4, 5, 6, 7, 8, 10, 12, 13, 14, 15]

Probably, more intuitive way would be like this

if type(e) is list:
    print('Found a list element inside the list') 

Note: if you are trying to get this information for tables that are in a different SCHEMA use the all_tab_columns view, we have this problem as our Applications use a different SCHEMA for security purposes.

use the following:

EG:

FROM
    all_tab_columns 
WHERE
    upper(table_name) = 'MY_TABLE_NAME' AND upper(column_name) = 'MY_COL_NAME'

I don't have enough rep to answer ClintEastwood, and the accepted answer is correct for the Web.config file. Adding this in for code difference.

When your mailSettings are set on Web.config, you don't need to do anything other than new up your SmtpClient and .Send. It finds the connection itself without needing to be referenced. You would change your C# from this:

SmtpClient smtpClient = new SmtpClient("smtp.sender.you", Convert.ToInt32(587));
System.Net.NetworkCredential credentials = new System.Net.NetworkCredential("username", "password");
smtpClient.Credentials = credentials;
smtpClient.Send(msgMail);  

To this:

SmtpClient smtpClient = new SmtpClient();
smtpClient.Send(msgMail);

To find the distance between 2 points, you need to find the length of the hypotenuse in a right angle triangle with a width and height equal to the vertical and horizontal distance:

Math.hypot(endX - startX, endY - startY)

Another possibility is to use separate lines to set up Make variables when a rule fires.

For example, here is a makefile with two rules. If a rule fires, it creates a temp dir and sets TMP to the temp dir name.

PHONY = ruleA ruleB display

all: ruleA

ruleA: TMP = $(shell mktemp -d testruleA_XXXX)
ruleA: display

ruleB: TMP = $(shell mktemp -d testruleB_XXXX)
ruleB: display

display:
    echo ${TMP}

Running the code produces the expected result:

$ ls
Makefile
$ make ruleB
echo testruleB_Y4Ow
testruleB_Y4Ow
$ ls
Makefile  testruleB_Y4Ow

How to create multiple plots from a dictionary of dataframes with long (tidy) data

• Assumptions

  • There is a dictionary of multiple dataframes of tidy data
    • Created by reading in from files
    • Created by separating a single dataframe into multiple dataframes
  • The categories, cat, may be overlapping, but all dataframes may not contain all values of cat
  • hue='cat'

• Because dataframes are being iterated through, there's not guarantee that colors will be mapped the same for each plot

  • A custom color map needs to be created from the unique 'cat' values for all the dataframes
  • Since the colors will be the same, place one legend to the side of the plots, instead of a legend in every plot

Imports and synthetic data

import numpy as np  # used for random data

The Json conversion should work out-of-the box. In order this to happen you need add some simple configurations:
First add a contentNegotiationManager into your spring config file. It is responsible for negotiating the response type:

<bean id="contentNegotiationManager"
      class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
    <property name="favorPathExtension" value="false" />
    <property name="favorParameter" value="true" />
    <property name="ignoreAcceptHeader" value="true" />
    <property name="useJaf" value="false" />
     <property name="defaultContentType" value="application/json" />

      <property name="mediaTypes">
         <map>
            <entry key="json" value="application/json" />
            <entry key="xml" value="application/xml" />
         </map>
      </property>
   </bean>

   <mvc:annotation-driven
      content-negotiation-manager="contentNegotiationManager" />

   <context:annotation-config />

Then add Jackson2 jars (jackson-databind and jackson-core) in the service's class path. Jackson is responsible for the data serialization to JSON. Spring will detect these and initialize the MappingJackson2HttpMessageConverter automatically for you. Having only this configured I have my automatic conversion to JSON working. The described config has an additional benefit of giving you the possibility to serialize to XML if you set accept:application/xml header.

This works on firefox 3.6.x and IE:

    function copyToClipboardCrossbrowser(s) {           
        s = document.getElementById(s).value;               

        if( window.clipboardData && clipboardData.setData )
        {
            clipboardData.setData("Text", s);
        }           
        else
        {
            // You have to sign the code to enable this or allow the action in about:config by changing
            //user_pref("signed.applets.codebase_principal_support", true);
            netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect');

            var clip = Components.classes["@mozilla.org/widget/clipboard;1"].createInstance(Components.interfaces.nsIClipboard);
            if (!clip) return;

            // create a transferable

            var trans = Components.classes["@mozilla.org/widget/transferable;1"].createInstance(Components.interfaces.nsITransferable);
            if (!trans) return;

            // specify the data we wish to handle. Plaintext in this case.
            trans.addDataFlavor('text/unicode');

            // To get the data from the transferable we need two new objects
            var str = new Object();
            var len = new Object();

            var str = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);

            str.data= s;        

            trans.setTransferData("text/unicode",str, str.data.length * 2);

            var clipid=Components.interfaces.nsIClipboard;              
            if (!clip) return false;
            clip.setData(trans,null,clipid.kGlobalClipboard);      
        }
    }

Here's the real solution (with other cool CSS3 stuff):

#fixed-square {
position: fixed;
top: 0;
right: 0;
z-index: 9500;
cursor: pointer;
width: 24px;
padding: 18px 18px 14px;
opacity: 0.618;
-webkit-transform: rotate(-90deg);
-moz-transform: rotate(-90deg);
-ms-transform: rotate(-90deg);
transform: rotate(-90deg);
-webkit-transition: all 0.145s ease-out;
-moz-transition: all 0.145s ease-out;
-ms-transition: all 0.145s ease-out;
transition: all 0.145s ease-out;
}

Note the top:0 and right:0. That's what did it for me.

You could do something like this:

create procedure test
as
BEGIN

    create table #ids
    (
        rn int,
        id int
    )

    insert into #ids (rn, id)
    select distinct row_number() over(order by id) as rn, id
    from table

    declare @id int
    declare @totalrows int = (select count(*) from #ids)
    declare @currentrow int = 0

    while @currentrow <  @totalrows  
    begin 
        set @id = (select id from #ids where rn = @currentrow)

        exec stored_proc @varName=@id, @otherVarName='test'

        set @currentrow = @currentrow +1
    end  

END

A case class is a class that may be used with the match/case statement.

def isIdentityFun(term: Term): Boolean = term match {
  case Fun(x, Var(y)) if x == y => true
  case _ => false
}

You see that case is followed by an instance of class Fun whose 2nd parameter is a Var. This is a very nice and powerful syntax, but it cannot work with instances of any class, therefore there are some restrictions for case classes. And if these restrictions are obeyed, it is possible to automatically define hashcode and equals.

The vague phrase "a recursive decomposition mechanism via pattern matching" means just "it works with case". (Indeed, the instance followed by match is compared to (matched against) the instance that follows case, Scala has to decompose them both, and has to recursively decompose what they are made of.)

What case classes are useful for? The Wikipedia article about Algebraic Data Types gives two good classical examples, lists and trees. Support for algebraic data types (including knowing how to compare them) is a must for any modern functional language.

What case classes are not useful for? Some objects have state, the code like connection.setConnectTimeout(connectTimeout) is not for case classes.

And now you can read A Tour of Scala: Case Classes

It's very easy, using jersey-client, just include this maven dependency:

<dependency>
  <groupId>org.glassfish.jersey.core</groupId>
  <artifactId>jersey-client</artifactId>
  <version>2.25.1</version>
</dependency>

Then invoke it using this example:

String json = ClientBuilder.newClient().target("http://api.coindesk.com/v1/bpi/currentprice.json").request().accept(MediaType.APPLICATION_JSON).get(String.class);

Then use Google's Gson to parse the JSON:

Gson gson = new Gson();
Type gm = new TypeToken<CoinDeskMessage>() {}.getType();
CoinDeskMessage cdm = gson.fromJson(json, gm);

String objects in Java use the UTF-16 encoding that can't be modified.

The only thing that can have a different encoding is a byte[]. So if you need UTF-8 data, then you need a byte[]. If you have a String that contains unexpected data, then the problem is at some earlier place that incorrectly converted some binary data to a String (i.e. it was using the wrong encoding).

Not sure if this is more concise, but this function will also find and allow replacement of NAs (or any value you like) in selected columns of a data.table:

update.mat <- function(dt, cols, criteria) {
  require(data.table)
  x <- as.data.frame(which(criteria==TRUE, arr.ind = TRUE))
  y <- as.matrix(subset(x, x$col %in% which((names(dt) %in% cols), arr.ind = TRUE)))
  y
}

To apply it:

y[update.mat(y, c("a", "b"), is.na(y))] <- 0

The function creates a matrix of the selected columns and rows (cell coordinates) that meet the input criteria (in this case is.na == TRUE).

Try to insert this:

DriverManager.registerDriver(new com.mysql.jdbc.Driver());

before getting the JDBC Connection.

Complete Code Examples/Alternative Methods

In the example in the code you have posted there is, in fact, no point in catching the exception as there is nothing done on the catch it is just re-thown, in fact it does more harm than good as the call stack is lost.

You would, however catch an exception to do some logic (for example closing sql connection of file lock, or just some logging) in the event of an exception the throw it back to the calling code to deal with. This would be more common in a business layer than front end code as you may want the coder implementing your business layer to handle the exception.

To re-iterate though the There is NO point in catching the exception in the example you posted. DON'T do it like that!

Don't update the primary key. It could cause a lot of problems for you keeping your data intact, if you have any other tables referencing it.

Ideally, if you want a unique field that is updateable, create a new field.

To use await/async you need methods that return promises. The core API functions don't do that without wrappers like promisify:

const fs = require('fs');
const util = require('util');

// Convert fs.readFile into Promise version of same    
const readFile = util.promisify(fs.readFile);

function getStuff() {
  return readFile('test');
}

// Can't use `await` outside of an async function so you need to chain
// with then()
getStuff().then(data => {
  console.log(data);
})

As a note, readFileSync does not take a callback, it returns the data or throws an exception. You're not getting the value you want because that function you supply is ignored and you're not capturing the actual return value.

Create a class that inherits from IActionFilter.

public class NoCacheAttribute : ActionFilterAttribute
{  
    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        filterContext.HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
        filterContext.HttpContext.Response.Cache.SetValidUntilExpires(false);
        filterContext.HttpContext.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
        filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);
        filterContext.HttpContext.Response.Cache.SetNoStore();

        base.OnResultExecuting(filterContext);
    }
}

Then put attributes where needed...

    [NoCache]
    [Authorize]
    public ActionResult ChangePassword()
    {

I really recommend you read about Information Theory, bayesian methods and MaxEnt. The place to start is this (freely available online) book by David Mackay:

http://www.inference.phy.cam.ac.uk/mackay/itila/

Those inference methods are really far more general than just text mining and I can't really devise how one would learn how to apply this to NLP without learning some of the general basics contained in this book or other introductory books on Machine Learning and MaxEnt bayesian methods.

The connection between entropy and probability theory to information processing and storing is really, really deep. To give a taste of it, there's a theorem due to Shannon that states that the maximum amount of information you can pass without error through a noisy communication channel is equal to the entropy of the noise process. There's also a theorem that connects how much you can compress a piece of data to occupy the minimum possible memory in your computer to the entropy of the process that generated the data.

I don't think it's really necessary that you go learning about all those theorems on communication theory, but it's not possible to learn this without learning the basics about what is entropy, how it's calculated, what is it's relationship with information and inference, etc...

I was catching GuzzleHttp\Exception\BadResponseException as @dado is suggesting. But one day I got GuzzleHttp\Exception\ConnectException when DNS for domain wasn't available. So my suggestion is - catch GuzzleHttp\Exception\ConnectException to be safe about DNS errors as well.

For Amazon s3 you need to edit your CORS configuration:

<CORSConfiguration>
    <CORSRule>
        <AllowedOrigin>*</AllowedOrigin>
        <AllowedMethod>GET</AllowedMethod>
        <MaxAgeSeconds>3000</MaxAgeSeconds>
        <AllowedHeader>Authorization</AllowedHeader>
    </CORSRule>
</CORSConfiguration>

Another option may be this John Resig remove method. can better fit what you need. if you know the index in the array.

Here's the nearly shortest possible solution to your question. The solution works in python 3.x. For python 2.x change the import to Tkinter rather than tkinter (the difference being the capitalization):

import tkinter as tk
#import Tkinter as tk  # for python 2
    
def create_window():
    window = tk.Toplevel(root)

root = tk.Tk()
b = tk.Button(root, text="Create new window", command=create_window)
b.pack()

root.mainloop()

This is definitely not what I recommend as an example of good coding style, but it illustrates the basic concepts: a button with a command, and a function that creates a window.

+ theme(plot.title = element_text(size=22))

Here is the full set of things you can change in element_text:

element_text(family = NULL, face = NULL, colour = NULL, size = NULL,
  hjust = NULL, vjust = NULL, angle = NULL, lineheight = NULL,
  color = NULL)

To improve on @bgporter's answer, with Python-3 you will probably want to operate on bytes instead of needlessly converting things to utf-8:

>>> import shutil
>>> import sys
>>> with open("test.txt", "rb") as f:
...    shutil.copyfileobj(f, sys.stdout.buffer)

A previous answer only mentioned SSL in the context of data transfer and didn't actually cover authentication.

You're really asking about securely authenticating REST API clients. Unless you're using TLS client authentication, SSL alone is NOT a viable authentication mechanism for a REST API. SSL without client authc only authenticates the server, which is irrelevant for most REST APIs because you really want to authenticate the client.

If you don't use TLS client authentication, you'll need to use something like a digest-based authentication scheme (like Amazon Web Service's custom scheme) or OAuth 1.0a or even HTTP Basic authentication (but over SSL only).

These schemes authenticate that the request was sent by someone expected. TLS (SSL) (without client authentication) ensures that the data sent over the wire remains untampered. They are separate - but complementary - concerns.

For those interested, I've expanded on an SO question about HTTP Authentication Schemes and how they work.

I surprise no one had mentioned this possible easy approach in visual studio code.

Its pretty quick which is intutitive enough, even newbies can very well start with a Maven project.

If you use copy-on-write collections it will work; however when you use list.iterator(), the returned Iterator will always reference the collection of elements as it was when ( as below ) list.iterator() was called, even if another thread modifies the collection. Any mutating methods called on a copy-on-write–based Iterator or ListIterator (such as add, set, or remove) will throw an UnsupportedOperationException.

import java.util.List;
import java.util.concurrent.CopyOnWriteArrayList;

public class RemoveListElementDemo {    
    private static final List<Integer> integerList;

    static {
        integerList = new CopyOnWriteArrayList<>();
        integerList.add(1);
        integerList.add(2);
        integerList.add(3);
    }

    public static void remove(Integer remove) {
        for(Integer integer : integerList) {
            if(integer.equals(remove)) {                
                integerList.remove(integer);
            }
        }
    }

    public static void main(String... args) {                
        remove(Integer.valueOf(2));

        Integer remove = Integer.valueOf(3);
        for(Integer integer : integerList) {
            if(integer.equals(remove)) {                
                integerList.remove(integer);
            }
        }
    }

BalusC is right. Version 1.0.13 is current, but 1.0.9 appears to have the required bundles:

You can get a request parameter id using the expression:

<h:outputText value="#{param['id']}" />

• param—An immutable Map of the request parameters for this request, keyed by parameter name. Only the first value for each parameter name is included.
• sessionScope—A Map of the session attributes for this request, keyed by attribute name.

Section 5.3.1.2 of the JSF 1.0 specification defines the objects that must be resolved by the variable resolver.

You can use `

view.getLocationOnScreen(int[] location)

;` to get location of your view correctly.

But there is a catch if you use it before layout has been inflated you will get wrong position.

Solution to this problem is adding ViewTreeObserver like this :-

Declare globally the array to store x y position of your view

 int[] img_coordinates = new int[2];

and then add ViewTreeObserver on your parent layout to get callback for layout inflation and only then fetch position of view otherwise you will get wrong x y coordinates

  // set a global layout listener which will be called when the layout pass is completed and the view is drawn
            parentViewGroup.getViewTreeObserver().addOnGlobalLayoutListener(
                    new ViewTreeObserver.OnGlobalLayoutListener() {
                        public void onGlobalLayout() {
                            //Remove the listener before proceeding
                            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                                parentViewGroup.getViewTreeObserver().removeOnGlobalLayoutListener(this);
                            } else {
                                parentViewGroup.getViewTreeObserver().removeGlobalOnLayoutListener(this);
                            }

                            // measure your views here
                            fab.getLocationOnScreen(img_coordinates);
                        }
                    }
            );

and then use it like this

xposition = img_coordinates[0];
yposition =  img_coordinates[1];

I've had success putting text within span tags and then setting vertical-align: middle on that span. Don't know how cross-browser compliant this is though, I've only tested it in webkit browsers.

You can't.

One workaround is to create clone environment, and then remove original one:

(remember about deactivating current environment with deactivate on Windows and source deactivate on macOS/Linux)

conda create --name new_name --clone old_name
conda remove --name old_name --all # or its alias: `conda env remove --name old_name`

There are several drawbacks of this method:

1. it redownloads packages - you can use --offline flag to disable it,
2. time consumed on copying environment's files,
3. temporary double disk usage.

There is an open issue requesting this feature.

This will get you the most expensive car for the user:

SELECT users.userName, MAX(cars.carPrice)
FROM users
LEFT JOIN cars ON cars.belongsToUser=users.id
WHERE users.id=4
GROUP BY users.userName

However, this statement makes me think that you want all of the cars prices sorted, descending:

So question: How do I set the LEFT JOIN table to be ordered by carPrice, DESC ?

So you could try this:

SELECT users.userName, cars.carPrice
FROM users
LEFT JOIN cars ON cars.belongsToUser=users.id
WHERE users.id=4
GROUP BY users.userName
ORDER BY users.userName ASC, cars.carPrice DESC

Here is a partial solution, still better than all published ones so far.

import sys, os, os.path, inspect

#os.chdir("..")

if '__file__' not in locals():
    __file__ = inspect.getframeinfo(inspect.currentframe())[0]

print os.path.dirname(os.path.abspath(__file__))

Now this works will all calls but if someone use chdir() to change the current directory, this will also fail.

Notes:

• sys.argv[0] is not going to work, will return -c if you execute the script with python -c "execfile('path-tester.py')"
• I published a complete test at https://gist.github.com/1385555 and you are welcome to improve it.

This is how I used this is as an example:

CAST(vAvgMaterialUnitCost.`avgUnitCost` AS DECIMAL(11,2)) * woMaterials.`qtyUsed` AS materialCost

you could submit all parameters with such naming:

params[0][topdiameter]
params[0][bottomdiameter]
params[1][topdiameter]
params[1][bottomdiameter]

then later you do something like this:

foreach ($_REQUEST['params'] as $item) {
    echo $item['topdiameter'];
    echo $item['bottomdiameter'];
}

Since there are many different kinds of casting each with different semantics, static_cast<> allows you to say "I'm doing a legal conversion from one type to another" like from int to double. A plain C-style cast can mean a lot of things. Are you up/down casting? Are you reinterpreting a pointer?

>>> a = [1, 3, 5]
>>> b = [1, 3, 5, 8]
>>> c = [3, 5, 9]
>>> set(a) <= set(b)
True
>>> set(c) <= set(b)
False

>>> a = ['yes', 'no', 'hmm']
>>> b = ['yes', 'no', 'hmm', 'well']
>>> c = ['sorry', 'no', 'hmm']
>>> 
>>> set(a) <= set(b)
True
>>> set(c) <= set(b)
False

This Works fine for me

var osvar = process.platform;

if (osvar == 'darwin') {
    console.log("you are on a mac os");
}else if(osvar == 'win32'){
    console.log("you are on a windows os")
}else{
    console.log("unknown os")
}

Check out yowsup
https://github.com/tgalal/yowsup

Yowsup is a python library that allows you to do all the previous in your own app. Yowsup allows you to login and use the Whatsapp service and provides you with all capabilities of an official Whatsapp client, allowing you to create a full-fledged custom Whatsapp client.

A solid example of Yowsup's usage is Wazapp. Wazapp is full featured Whatsapp client that is being used by hundreds of thousands of people around the world. Yowsup is born out of the Wazapp project. Before becoming a separate project, it was only the engine powering Wazapp. Now that it matured enough, it was separated into a separate project, allowing anyone to build their own Whatsapp client on top of it. Having such a popular client as Wazapp, built on Yowsup, helped bring the project into a much advanced, stable and mature level, and ensures its continuous development and maintaince.

Yowsup also comes with a cross platform command-line frontend called yowsup-cli. yowsup-cli allows you to jump into connecting and using Whatsapp service directly from command line.

time is a built-in command in most shells that writes execution time information to the tty.

You could also try something like

start_time=`date +%s`
<command-to-execute>
end_time=`date +%s`
echo execution time was `expr $end_time - $start_time` s.

Or in bash:

start_time=`date +%s`
<command-to-execute> && echo run time is $(expr `date +%s` - $start_time) s

Using Maria-DB and DB-Navigator tool inside IntelliJ, MODIFY Column worked for me instead of Alter Column

Improving Suman.hassan95's answer by adding a link to subcategory as well. Replace the following code:

$sub_cats = get_categories( $args2 );
    if($sub_cats) {
        foreach($sub_cats as $sub_category) {
            echo  $sub_category->name ;
        }

    }

with:

$sub_cats = get_categories( $args2 );
            if($sub_cats) {
                foreach($sub_cats as $sub_category) {
                    echo  '<br/><a href="'. get_term_link($sub_category->slug, 'product_cat') .'">'. $sub_category->name .'</a>';
                }
            }

or if you also wish a counter for each subcategory, replace with this:

$sub_cats = get_categories( $args2 );
            if($sub_cats) {
                foreach($sub_cats as $sub_category) {
                    echo  '<br/><a href="'. get_term_link($sub_category->slug, 'product_cat') .'">'. $sub_category->name .'</a>';
                    echo apply_filters( 'woocommerce_subcategory_count_html', ' <span class="cat-count">' . $sub_category->count . '</span>', $category );
                }
            }

This will make an orange and gray border using the class="myclass" on the div.

.myclass {
    outline:dashed darkorange  12px;
    border:solid slategray  14px;
    outline-offset:-14px;
}

I prefer to use the ngModel and ngChange directives when dealing with checkboxes. ngModel allows you to bind the checked/unchecked state of the checkbox to a property on the entity:

<input type="checkbox" ng-model="entity.isChecked">

Whenever the user checks or unchecks the checkbox the entity.isChecked value will change too.

If this is all you need then you don't even need the ngClick or ngChange directives. Since you have the "Check All" checkbox, you obviously need to do more than just set the value of the property when someone checks a checkbox.

When using ngModel with a checkbox, it's best to use ngChange rather than ngClick for handling checked and unchecked events. ngChange is made for just this kind of scenario. It makes use of the ngModelController for data-binding (it adds a listener to the ngModelController's $viewChangeListeners array. The listeners in this array get called after the model value has been set, avoiding this problem).

<input type="checkbox" ng-model="entity.isChecked" ng-change="selectEntity()">

... and in the controller ...

var model = {};
$scope.model = model;

// This property is bound to the checkbox in the table header
model.allItemsSelected = false;

// Fired when an entity in the table is checked
$scope.selectEntity = function () {
    // If any entity is not checked, then uncheck the "allItemsSelected" checkbox
    for (var i = 0; i < model.entities.length; i++) {
        if (!model.entities[i].isChecked) {
            model.allItemsSelected = false;
            return;
        }
    }

    // ... otherwise ensure that the "allItemsSelected" checkbox is checked
    model.allItemsSelected = true;
};

Similarly, the "Check All" checkbox in the header:

<th>
    <input type="checkbox" ng-model="model.allItemsSelected" ng-change="selectAll()">
</th>

... and ...

// Fired when the checkbox in the table header is checked
$scope.selectAll = function () {
    // Loop through all the entities and set their isChecked property
    for (var i = 0; i < model.entities.length; i++) {
        model.entities[i].isChecked = model.allItemsSelected;
    }
};

CSS

What is the best way to... add a CSS class to the <tr> containing the entity to reflect its selected state?

If you use the ngModel approach for the data-binding, all you need to do is add the ngClass directive to the <tr> element to dynamically add or remove the class whenever the entity property changes:

<tr ng-repeat="entity in model.entities" ng-class="{selected: entity.isChecked}">

If you are trying to use javascript to avoid using SSL, think again. There are many half-way measures, but only SSL provides secure communication. Javascript encryption libraries can help against a certain set of attacks, but not a true man-in-the-middle attack.

The following article explains how to attempt to create secure communication with javascript, and how to get it wrong: Use JavaScript encryption module instead of SSL/HTTPS

Note: If you are looking for SSL for google app engine on a custom domain, take a look at wwwizer.com.
