Using dialog methods:

$('.selectorUsedToCreateTheDialog').dialog('option', 'title', 'My New title');

Or directly, hacky though:

$("span.ui-dialog-title").text('My New Title'); 

For future reference, you can skip google with jQuery. The jQuery API will answer your questions most of the time. In this case, the Dialog API page. For the main library: http://api.jquery.com

The latest jQuery UI has a position component:

$("#myDialog").position({
   my: "center",
   at: "center",
   of: window
});

It's destroy and destroy_all methods, like

user.destroy
User.find(15).destroy
User.destroy(15)
User.where(age: 20).destroy_all
User.destroy_all(age: 20)

Alternatively you can use delete and delete_all which won't enforce :before_destroy and :after_destroy callbacks or any dependent association options.

User.delete_all(condition: 'value') will allow you to delete records without a primary key

Note: from @hammady's comment, user.destroy won't work if User model has no primary key.

Note 2: From @pavel-chuchuva's comment, destroy_all with conditions and delete_all with conditions has been deprecated in Rails 5.1 - see guides.rubyonrails.org/5_1_release_notes.html

Here's a solution to your problem using dplyr's filter function.

Although you can pass your data frame as the first argument to any dplyr function, I've used its %>% operator, which pipes your data frame to one or more dplyr functions (just filter in this case).

Once you are somewhat familiar with dplyr, the cheat sheet is very handy.

> print(df <- data.frame(sub=rep(1:3, each=4), day=1:4))
   sub day
1    1   1
2    1   2
3    1   3
4    1   4
5    2   1
6    2   2
7    2   3
8    2   4
9    3   1
10   3   2
11   3   3
12   3   4
> print(df <- df %>% filter(!((sub==1 & day==2) | (sub==3 & day==4))))
   sub day
1    1   1
2    1   3
3    1   4
4    2   1
5    2   2
6    2   3
7    2   4
8    3   1
9    3   2
10   3   3

I always use this.It send form data using ajax

$(document).on("submit", "form", function(event)
{
    event.preventDefault();

    var url=$(this).attr("action");
    $.ajax({
        url: url,
        type: 'POST',            
        data: new FormData(this),
        processData: false,
        contentType: false,
        success: function (data, status)
        {

        }
    });
});

You will either have to specify a DEFAULT, or add the column with NULLs allowed, update all the values, and then change the column to NOT NULL.

ALTER TABLE <YourTable> 
ADD <NewColumn> <NewColumnType> NOT NULL DEFAULT <DefaultValue>

I have spent the last few days trying to figure this out myself. Using the old json dataType gives you cross origin problems, while setting the dataType to jsonp makes the data "unreadable" as explained above. So there are apparently two ways out, the first hasn't worked for me but seems like a potential solution and that I might be doing something wrong. This is explained here [ https://learn.jquery.com/ajax/working-with-jsonp/ ].

The one that worked for me is as follows: 1- download the ajax cross origin plug in [ http://www.ajax-cross-origin.com/ ]. 2- add a script link to it just below the normal jQuery link. 3- add the line "crossOrigin: true," to your ajax function.

Good to go! here is my working code for this:

  $.ajax({_x000D_
      crossOrigin: true,_x000D_
      url : "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.86,151.195&radius=5000&type=ATM&keyword=ATM&key=MyKey",_x000D_
      type : "GET",_x000D_
      success:function(data){_x000D_
         console.log(data);_x000D_
      }_x000D_
    })

First you need to remember that in Unix and Linux, everything is a file, even directories. For a file to have the rights to be executed as a command, it needs to satisfy 3 conditions:

1. It needs to be a regular file
2. It needs to have read-permissions
3. It needs to have execute-permissions

So this can be done simply with:

[ -f "${file}" ] && [ -r "${file}" ] && [ -x "${file}" ]

If your file is a symbolic link to a regular file, the test command will operate on the target and not the link-name. So the above command distinguishes if a file can be used as a command or not. So there is no need to pass the file first to realpath or readlink or any of those variants.

If the file can be executed on the current OS, that is a different question. Some answers above already pointed to some possibilities for that, so there is no need to repeat it here.

Try this:

ALTER DATABASE [DATABASE_NAME]
SET SINGLE_USER
WITH ROLLBACK IMMEDIATE

(np.where(np.isnan(A)))[0].shape[0] will be greater than 0 if A contains at least one element of nan, A could be an n x m matrix.

Example:

import numpy as np

A = np.array([1,2,4,np.nan])

if (np.where(np.isnan(A)))[0].shape[0]: 
    print "A contains nan"
else:
    print "A does not contain nan"

This answer by Jaap :

<div class="image"></div>?

and in CSS :

div.image {
   content:url(http://placehold.it/350x150);
}?

you can try it on this link : http://jsfiddle.net/XAh2d/

this is a link about css content http://css-tricks.com/css-content/

This has been tested on Chrome, firefox and Safari. (I'm on a mac, so if someone has the result on IE, tell me to add it)

You can't declare a variable as Decimal - you have to use Variant (you can use CDec to populate it with a Decimal type though).

Check your JNI/native code. One of my references was null, but it was intermittent, so it wasn't very obvious.

Working my way through Fluent Python (Ramalho) - highly recommended. List comprehension one-ish-liners inspired by Chapter 2:

onlyascii = ''.join([s for s in data if ord(s) < 127])
onlymatch = ''.join([s for s in data if s in
              'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'])

you forgotten to add the sqlserver.jar in eclipse external library follow the process to add jar files

1. Right click on your project.
2. click buildpath
3. click configure bulid path
4. click add external jar and then give the path of jar

I found that the accepted answer didn't suffice, since X-FRAME-OPTIONS: Allow-From isn't supported in safari or chrome. Went with a different approach instead, found in a presentation given by Ben Vinegar from Disqus. The idea is to add an event listener to the parent window, and then inside the iframe, use window.postMessage to send an event to the parent telling it to do something (resize the iframe).

So in the parent document, add an event listener:

window.addEventListener('message', function(e) {
  var $iframe = jQuery("#myIframe");
  var eventName = e.data[0];
  var data = e.data[1];
  switch(eventName) {
    case 'setHeight':
      $iframe.height(data);
      break;
  }
}, false);

And inside the iframe, write a function to post the message:

function resize() {
  var height = document.getElementsByTagName("html")[0].scrollHeight;
  window.parent.postMessage(["setHeight", height], "*"); 
}

Finally, inside the iframe, add an onLoad to the body tag to fire the resize function:

<body onLoad="resize();">

I felt the below approach is very easy.

I have declared an interface for callback

public interface AsyncResponse {
    void processFinish(Object output);
}

Then created asynchronous Task for responding all type of parallel requests

 public class MyAsyncTask extends AsyncTask<Object, Object, Object> {

    public AsyncResponse delegate = null;//Call back interface

    public MyAsyncTask(AsyncResponse asyncResponse) {
        delegate = asyncResponse;//Assigning call back interfacethrough constructor
    }

    @Override
    protected Object doInBackground(Object... params) {

      //My Background tasks are written here

      return {resutl Object}

    }

    @Override
    protected void onPostExecute(Object result) {
        delegate.processFinish(result);
    }

}

Then Called the asynchronous task when clicking a button in activity Class.

public class MainActivity extends Activity{

    @Override
    public void onCreate(Bundle savedInstanceState) {

    Button mbtnPress = (Button) findViewById(R.id.btnPress);

    mbtnPress.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                MyAsyncTask asyncTask =new MyAsyncTask(new AsyncResponse() {

                    @Override
                    public void processFinish(Object output) {
                        Log.d("Response From Asynchronous task:", (String) output);

                        mbtnPress.setText((String) output);
                   }
                });

                asyncTask.execute(new Object[] { "Your request to aynchronous task class is giving here.." });


            }
        });

    }



}

Thanks

The cross browser way to do is to use childNodes to get NodeList, then make an array of all nodes with nodeType ELEMENT_NODE.

/**
 * Return direct children elements.
 *
 * @param {HTMLElement}
 * @return {Array}
 */
function elementChildren (element) {
    var childNodes = element.childNodes,
        children = [],
        i = childNodes.length;

    while (i--) {
        if (childNodes[i].nodeType == 1) {
            children.unshift(childNodes[i]);
        }
    }

    return children;
}

http://jsfiddle.net/s4kxnahu/

This is especially easy if you are using a utility library such as lodash:

/**
 * Return direct children elements.
 *
 * @param {HTMLElement}
 * @return {Array}
 */
function elementChildren (element) {
    return _.where(element.childNodes, {nodeType: 1});
}

Future:

You can use querySelectorAll in combination with :scope pseudo-class (matches the element that is the reference point of the selector):

parentElement.querySelectorAll(':scope > *');

At the time of writing this :scope is supported in Chrome, Firefox and Safari.

Reviewing the Apple Developer documentation I found the CFUUID object is available on the iPhone OS 2.0 and later.

The route-map express example matches url paths with objects which in turn matches http verbs with functions. This lays the routing out in a tree, which is concise and easy to read. The apps's entities are also written as objects with the functions as enclosed methods.

var express = require('../../lib/express')
  , verbose = process.env.NODE_ENV != 'test'
  , app = module.exports = express();

app.map = function(a, route){
  route = route || '';
  for (var key in a) {
    switch (typeof a[key]) {
      // { '/path': { ... }}
      case 'object':
        app.map(a[key], route + key);
        break;
      // get: function(){ ... }
      case 'function':
        if (verbose) console.log('%s %s', key, route);
        app[key](route, a[key]);
        break;
    }
  }
};

var users = {
  list: function(req, res){
    res.send('user list');
  },

  get: function(req, res){
    res.send('user ' + req.params.uid);
  },

  del: function(req, res){
    res.send('delete users');
  }
};

var pets = {
  list: function(req, res){
    res.send('user ' + req.params.uid + '\'s pets');
  },

  del: function(req, res){
    res.send('delete ' + req.params.uid + '\'s pet ' + req.params.pid);
  }
};

app.map({
  '/users': {
    get: users.list,
    del: users.del,
    '/:uid': {
      get: users.get,
      '/pets': {
        get: pets.list,
        '/:pid': {
          del: pets.del
        }
      }
    }
  }
});

app.listen(3000);

Use this line of code:

Thread.sleep(1000);

It will sleep for 1 second.

If you deal regularly with Attributes in Reflection, it is very, very practical to define some extension methods. You will see that in many projects out there. This one here is one I often have:

public static bool HasAttribute<T>(this ICustomAttributeProvider provider) where T : Attribute
{
  var atts = provider.GetCustomAttributes(typeof(T), true);
  return atts.Length > 0;
}

which you can use like typeof(Foo).HasAttribute<BarAttribute>();

Other projects (e.g. StructureMap) have full-fledged ReflectionHelper classes that use Expression trees to have a fine syntax to identity e.g. PropertyInfos. Usage then looks like that:

ReflectionHelper.GetProperty<Foo>(x => x.MyProperty).HasAttribute<BarAttribute>()

If it is a command file you are looking for, the fastest and most accurate way is with

which "commandname"

That will show you the actual file being used for the command, even if you have many files with the same name on the system.

I combined a few answers given by others in this question to come up with another alternative solution.

Goal: To always bundle the files, to disable the JS and CSS minification in the event that <compilation debug="true" ... /> and to always apply a custom transformation to the CSS bundle.

My solution:

1) In web.config: <compilation debug="true" ... />

2) In the Global.asax Application_Start() method:

 protected void Application_Start() {
     ...
     BundleTable.EnableOptimizations = true; // Force bundling to occur

     // If the compilation node in web.config indicates debugging mode is enabled
     // then clear all transforms. I.e. disable Js and CSS minification.
     if (HttpContext.Current.IsDebuggingEnabled) {
         BundleTable.Bundles.ToList().ForEach(b => b.Transforms.Clear());
     }

      // Add a custom CSS bundle transformer. In my case the transformer replaces a
      // token in the CSS file with an AppConfig value representing the website URL
      // in the current environment. E.g. www.mydevwebsite in Dev and
      // www.myprodwebsite.com in Production.
      BundleTable.Bundles.ToList()
          .FindAll(x => x.GetType() == typeof(StyleBundle))
          .ForEach(b => b.Transforms.Add(new MyStyleBundleTransformer()));
     ...
}

Your first CSS selector—social.h2—is looking for the "social" element in the "h2", class, e.g.:

<social class="h2">

Class selectors are proceeded with a dot (.). Also, use a space () to indicate that one element is inside of another. To find an <h2> descendant of an element in the social class, try something like:

.social h2 {
  color: pink;
  font-size: 14px;
}

To get a better understanding of CSS selectors and how they are used to reference your HTML, I suggest going through the interactive HTML and CSS tutorials from CodeAcademy. I hope that this helps point you in the right direction.

To expand on @neubert answer, if you are using Laravel 5 or similar, you can use phpseclib much simpler like this:

Run composer require phpseclib/phpseclib ~2.0

In your controller add

use phpseclib\Net\SSH2;

Then use it in a controller method like:

 $host = config('ssh.host');
 $username = config('ssh.username');
 $password = config('ssh.password'); 
 $command = 'php version';

 $ssh = new SSH2($host);
    if (!$ssh->login($username, $password)) {
        $output ='Login Failed';
    }
    else{
        $output = $ssh->exec($command);
 }

Back in 2002, Novell developed some software called NetDrive that can map a WebDAV, FTP, SFTP, etc. share to a windows drive letter. It is now abandonware, so it's no longer maintained (and not available on the Novell website), but it's free to use. I found quite a few available to download by searching for "netdrive.exe" I actually downloaded a few and compared their md5sums to make sure that I was getting a common (and hopefully safe) version.

Update 10 Nov 2017 SFTPNetDrive is the current project from the original netdrive project. And they made it free for personal use:

We Made SFTP Net Drive FREE for Personal Use

They have paid options as well on the website.

I had a lab with App Review team (WWDC20).

My questions were:

1. My app is making calls through HTTPS only. Should I select Yes or No?
2. Should I send report to the US government if my app available in Germany only (doesn't available in the USA)?

Answers:

1. If you just use HTTPS you can select No

2. The answer on the second question was unclear. Helpful link Looks like yes if you're using custom encryption.

First of all, it is a waste of an executor slot to wrap the build step in node. Your upstream executor will just be sitting idle for no reason.

Second, from a multibranch project, you can use the environment variable BRANCH_NAME to make logic conditional on the current branch.

Third, the job parameter takes an absolute or relative job name. If you give a name without any path qualification, that would refer to another job in the same folder, which in the case of a multibranch project would mean another branch of the same repository.

Thus what you meant to write is probably

if (env.BRANCH_NAME == 'master') {
    build '../other-repo/master'
}

Add the HTTP header manager and add in it your API's header names and values. e.g. Content-type, Accept, etc. That will resolve your issue.

Am I missing something? You can just convert offer_date in the comparison:

SELECT *
FROM offers
WHERE to_char(offer_date, 'YYYYMM') = (SELECT to_date(create_date, 'YYYYMM') FROM customers where id = '12345678') AND
      offer_rate > 0 

My solution for a better user experience:

HTML

<input type="tel">

jQuery

$('[type=tel]').on('change', function(e) {
  $(e.target).val($(e.target).val().replace(/[^\d\.]/g, ''))
})
$('[type=tel]').on('keypress', function(e) {
  keys = ['0','1','2','3','4','5','6','7','8','9','.']
  return keys.indexOf(event.key) > -1
})

Details:

First of all, input types:

number shows up/down arrows shrinking the actual input space, I find them ugly and are only useful if the number represents a quantity (things like phones, area codes, IDs... don't need them) tel provides similar browser validations of number without arrows

Using [number / tel] also helps showing numeric keyboard on mobile devices.

For the JS validation I ended up needing 2 functions, one for the normal user input (keypress) and the other for a copy+paste fix (change), other combinations would give me a terrible user experience.

I use the more reliable KeyboardEvent.key instead of the now deprecated KeyboardEvent.charCode

And depending of your browser support you can consider using Array.prototype.includes() instead of the poorly named Array.prototype.indexOf() (for true / false results)

json_decode will return the same array that was originally encoded. For instanse, if you

$array = json_decode($json, true);
echo $array['countryId'];

OR

$obj= json_decode($json);

echo $obj->countryId;

These both will echo 84. I think json_encode and json_decode function names are self-explanatory...

 this.requestWindowFeature(getWindow().FEATURE_NO_TITLE);

You can get the example and sample code at the official site, as following:

<TextInput password={true} style={styles.default} value="abc" />

Reference: http://facebook.github.io/react-native/docs/textinput.html

In Android Studio open: File > Project Structure and check if JDK location points to your JDK 1.8 directory.

Note: you can use compileSdkVersion 24. It works trust me. For this to work first download latest JDK from Oracle.

How can I display these open transactions and commit or cancel them?

There is no open transaction, MySQL will rollback the transaction upon disconnect.
You cannot commit the transaction (IFAIK).

You display threads using

SHOW FULL PROCESSLIST  

See: http://dev.mysql.com/doc/refman/5.1/en/thread-information.html

It will not help you, because you cannot commit a transaction from a broken connection.

What happens when a connection breaks
From the MySQL docs: http://dev.mysql.com/doc/refman/5.0/en/mysql-tips.html

4.5.1.6.3. Disabling mysql Auto-Reconnect

If the mysql client loses its connection to the server while sending a statement, it immediately and automatically tries to reconnect once to the server and send the statement again. However, even if mysql succeeds in reconnecting, your first connection has ended and all your previous session objects and settings are lost: temporary tables, the autocommit mode, and user-defined and session variables. Also, any current transaction rolls back.

This behavior may be dangerous for you, as in the following example where the server was shut down and restarted between the first and second statements without you knowing it:

Also see: http://dev.mysql.com/doc/refman/5.0/en/auto-reconnect.html

How to diagnose and fix this
To check for auto-reconnection:

If an automatic reconnection does occur (for example, as a result of calling mysql_ping()), there is no explicit indication of it. To check for reconnection, call mysql_thread_id() to get the original connection identifier before calling mysql_ping(), then call mysql_thread_id() again to see whether the identifier has changed.

Make sure you keep your last query (transaction) in the client so that you can resubmit it if need be.
And disable auto-reconnect mode, because that is dangerous, implement your own reconnect instead, so that you know when a drop occurs and you can resubmit that query.

Use some preprocessor macro to check if it's in windows or linux. For example

#ifdef WIN32
LIB= 
#elif __GNUC__
LIB=wsock32
#endif

include -l$(LIB) in you build command.

You can also specify some command line argument to differentiate both.

Right value is below. (Tried)

maxRequestLength="2147483647" targetFramework="4.5.2"/>

You can cast this value to a Boolean in a very simple manner: by comparing it with integer value 1, like this:

boolean multipleContacts = new Integer(1).equals(jsonObject.get("MultipleContacts"))

If it is a String, you could do this:

boolean multipleContacts = "1".equals(jsonObject.get("MultipleContacts"))

In Python there is a method for doing this: driver.refresh(). It may not be the same in Java.

Alternatively, you could driver.get("http://foo.bar");, although I think the refresh method should work just fine.

From the Python glossary:

An object is hashable if it has a hash value which never changes during its lifetime (it needs a __hash__() method), and can be compared to other objects (it needs an __eq__() or __cmp__() method). Hashable objects which compare equal must have the same hash value.

Hashability makes an object usable as a dictionary key and a set member, because these data structures use the hash value internally.

All of Python’s immutable built-in objects are hashable, while no mutable containers (such as lists or dictionaries) are. Objects which are instances of user-defined classes are hashable by default; they all compare unequal, and their hash value is their id().

This behavior is related to Zone that is set - Internet/Intranet/etc and corresponding Security Level

You can change this by setting less secure Security Level (not recommended) or by customizing Display Mixed Content property

You can do that by following steps:

1. Click on Gear icon at the top of the browser window.
2. Select Internet Options.
3. Select the Security tab at the top.
4. Click the Custom Level... button.
5. Scroll about halfway down to the Miscellaneous heading (denoted by a "blank page" icon).
6. Under this heading is the option Display Mixed Content; set this to Enable/Prompt.
7. Click OK, then Yes when prompted to confirm the change, then OK to close the Options window.
8. Close and restart the browser.

I am learning Spring Data JPA. It might help you:

public void schedule(TimerTask task,long delay)

Schedules the specified task for execution after the specified delay.

you want:

public void schedule(TimerTask task, long delay, long period)

Schedules the specified task for repeated fixed-delay execution, beginning after the specified delay. Subsequent executions take place at approximately regular intervals separated by the specified period.

Yes, there is. You can use the Arrays class from the java.util.* package. Then it's actually just one line of code.

List<String> list = Arrays.asList(array);

Use ?:

<form action="?" method="post">

It will send the user back to the same page.

IPInfoDB has an API that you can call in order to find a location based on an IP address.

For "City Precision", you call it like this (you'll need to register to get a free API key):

 http://api.ipinfodb.com/v2/ip_query.php?key=<your_api_key>&ip=74.125.45.100&timezone=false

Here's an example in both VB and C# that shows how to call the API.

php > 7

use the new interface Throwable

    try {
        // Code that may throw an Exception or Error.
    } catch (Throwable $t) {
        // Handle exception
    }

echo "Script is still running..."; // this script will be executed.

Your task declaration is incorrectly combining the Copy task type and project.copy method, resulting in a task that has nothing to copy and thus never runs. Besides, Copy isn't the right choice for renaming a directory. There is no Gradle API for renaming, but a bit of Groovy code (leveraging Java's File API) will do. Assuming Project1 is the project directory:

task renABCToXYZ {     doLast {         file("ABC").renameTo(file("XYZ"))     } } 

Looking at the bigger picture, it's probably better to add the renaming logic (i.e. the doLast task action) to the task that produces ABC.

Instead of fixing your "master" branch, it's way easier to swap it with your "desired-master" by renaming the branches. See https://stackoverflow.com/a/2862606/2321594. This way you wouldn't even leave any trace of multiple revert logs.

We can access the matched group in a regular expressions by using backslash followed by number of the matching group:

/([a-z])\1/

In the code \1 represented matched by first group ([a-z])

def anotherFunction(word):
    for letter in word:              
        print("_", end=" ")

def oneFunction(lists):
    category = random.choice(list(lists.keys()))
    word = random.choice(lists[category])
    return anotherFunction(word)

I've put together a utility method which employs all tips shown here plus some more:

        //1 local should never happen with the default settings but it can happen when settings get overriden   we want to forcibly return utc though
    }

Notice the use of '-' and 'T' (single-quoted). This is done as a matter of best practice since regional settings interfere with the interpretation of chars such as '-' causing it to be interpreted as '/' or '.' or whatever your regional settings denote as date-components-separator. I have also included a second utility method which show-cases how to parse most commonly seen date-string formats fed to rest-api backends from web clients. Enjoy.

1. A yes-or-no problem is in P (Polynomial time) if the answer can be computed in polynomial time.
2. A yes-or-no problem is in NP (Non-deterministic Polynomial time) if a yes answer can be verified in polynomial time.

Intuitively, we can see that if a problem is in P, then it is in NP. Given a potential answer for a problem in P, we can verify the answer by simply recalculating the answer.

Less obvious, and much more difficult to answer, is whether all problems in NP are in P. Does the fact that we can verify an answer in polynomial time mean that we can compute that answer in polynomial time?

There are a large number of important problems that are known to be NP-complete (basically, if any these problems are proven to be in P, then all NP problems are proven to be in P). If P = NP, then all of these problems will be proven to have an efficient (polynomial time) solution.

Most scientists believe that P!=NP. However, no proof has yet been established for either P = NP or P!=NP. If anyone provides a proof for either conjecture, they will win US $1 million.

You can simply use javascript :)

How can you insert String result of function into buildConfigField

Here's an example of build date in human-readable format set:

def getDate() {
    return new SimpleDateFormat("dd MMMM yyyy", new Locale("ru")).format(new Date())
}

def buildDate = getDate()

defaultConfig {
    buildConfigField "String", "BUILD_DATE", "\"$buildDate\""
}

In XML, this what I use for achieving the same result. May be this is more intuitive.

scale_up.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

<scale
    android:duration="200"
    android:fromXScale="1.0"
    android:fromYScale="0.0"
    android:pivotX="50%"
    android:pivotY="100%"
    android:toXScale="1.0"
    android:toYScale="1.0" />

</set>

scale_down.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

<scale
    android:duration="200"
    android:fromXScale="1.0"
    android:fromYScale="1.0"
    android:pivotX="50%"
    android:pivotY="100%"
    android:toXScale="1.0"
    android:toYScale="0.0" />

</set>

See the animation on the X axis is from 1.0 -> 1.0 which means you don't have any scaling up in that direction and stays at the full width while, on the Y axis you get 0.0 -> 1.0 scaling, as shown in the graphic in the question. Hope this helps someone.

Some might want to know the java code as we see one requested.

Place the animation files in anim folder and then load and set animation files something like.

Animation scaleDown = AnimationUtils.loadAnimation(youContext, R.anim.scale_down);
ImagView v = findViewById(R.id.your_image_view);
v.startAnimation(scaleDown);

This is what worked for me on Mac OS Catalina -- found here (thanks, Josiah!)

If you're on Mac OS Catalina, you need to edit your .zprofile instead of .bash_profile.

1. Edit your ~/.zprofile file: vim ~/.zprofile
2. Add the following code in it, on it's own line: code () { VSCODE_CWD="$PWD" open -n -b "com.microsoft.VSCode" --args $* ;}
3. Save the file: :wq
4. Re-run the updated file: source ~/.zprofile.
5. Test that running code . opens your current folder in VS Code!

Another common cause of this error on the Mac is Apple's quarantine flag.

ls the directory containing the resource(s) in question. If you see the extended attribute indicator, i.e., the little @ symbol at the end of the permissions block (e.g. -rw-r--r--@ ) then the file could be quarantined.

Try ls -la@e and look for com.apple.quarantine

The following command will remove the quarantine:

xattr -d com.apple.quarantine /path/to/file

Make the exception happen like this:

when(obj.someMethod()).thenThrow(new AnException());

Verify it has happened either by asserting that your test will throw such an exception:

@Test(expected = AnException.class)

Or by normal mock verification:

verify(obj).someMethod();

The latter option is required if your test is designed to prove intermediate code handles the exception (i.e. the exception won't be thrown from your test method).

this will point to the <ul> selected by .nav-list. You can use delegation instead!

$('.nav-list').on('click', 'li', function() {
    $('.nav-list li.active').removeClass('active');
    $(this).addClass('active');
});

The code is very long so I can't paste all the code.

There could be any number of reasons why your code doesn't work. Maybe you declared the button variables twice so you aren't actually changing enabling/disabling the button like you think you are. Maybe you are blocking the EDT.

You need to create a SSCCE to post on the forum.

So its up to you to isolate the problem. Start with a simple frame thas two buttons and see if your code works. Once you get that working, then try starting a Thread that simply sleeps for 10 seconds to see if it still works.

Learn how the basice work first before writing a 200 line program.

Learn how to do some basic debugging, we are not mind readers. We can't guess what silly mistake you are doing based on your verbal description of the problem.

Bonus answer: The keyboard shortcut in Visual Studio for commenting out anything is Ctrl-KC . This works in a number of places, including C#, VB, Javascript, and aspx pages; it also works for SQL in SQL Management Studio.

You can either select the text to be commented out, or you can position your text inside a chunk to be commented out; for example, put your cursor inside the opening tag of a GridView, press Ctrl-KC, and the whole thing is commented out.

You can create a backup device in server object, let us say

BDTEST

and then create a batch file contain following command

sqlcmd -S 192.168.1.25 -E -Q "BACKUP DATABASE dbtest TO BDTEST"

let us say with name

backup.bat

then you can call

backup.bat

in task scheduler according to your convenience

If I understand you right, you can do this:

<img src="image.png" style="background-color:red;" />

In fact, you can even apply a whole background-image to the image, resulting in two "layers" without the need for multi-background support in the browser ;)

I've created a blog post entry which explains how to add code syntax highlighting to blogger using the syntaxhighlighter 2.0

Here's my blog post:

http://www.craftyfella.com/2010/01/syntax-highlighting-with-blogger-engine.html

I hope it helps you guys.. I'm quite impressed with what it can do.

Above Links stopped working. Try using http://hilite.me/

You'll need to order by the same field you're ordering by now, but descending. As an example, if you have a time stamp when the upload was done called upload_time, you'd do something like this;

For Pre-Laravel 4

return DB::table('files')->order_by('upload_time', 'desc')->first();

For Laravel 4 and onwards

return DB::table('files')->orderBy('upload_time', 'desc')->first();

For Laravel 5.7 and onwards

return DB::table('files')->latest('upload_time')->first();

This will order the rows in the files table by upload time, descending order, and take the first one. This will be the latest uploaded file.

# file? will only return true for files
File.file?(filename)

and

# Will also return true for directories - watch out!
File.exist?(filename)

matrix.size according to the numpy docs returns the Number of elements in the array. Hope that helps.

I had same issue. I found the answer:

ini_set('memory_limit', '-1');

Note: It will take unlimited memory usage of server.

Update: Use this carefully as this might slow down your system if the PHP script starts using an excessive amount of memory, causing a lot of swap space usage. You can use this if you know program will not take much memory and also you don't know how much to set it right now. But you will eventually find it how much memory you require for that program.

You should always memory limit as some value as answered by @sarki dinle.

ini_set('memory_limit', '512M');

Giving unlimited memory is bad practice, rather we should give some max limit that we can bear and then optimise our code or add some RAMs.

Just like in this question (npm global path prefix) all you need is to set proper npm prefix.

UNIX:

$ npm config set prefix /usr/local
$ npm install -g bower

$ which bower
>> /usr/local/bin/bower

Windows ans NVM:

$ npm config set prefix /c/Users/xxxxxxx/AppData/Roaming/nvm/v8.9.2
$ npm install -g bower

Then bower should be located just in your $PATH.

import requests
r = requests.get("https://stackoverflow.com")

There are few ways to create empty Set in Python :

1. Using set() method
   This is the built-in method in python that creates Empty set in that variable.
2. Using clear() method (creative Engineer Technique LOL)
   See this Example:
   
   sets={"Hi","How","are","You","All"}
   type(sets)  (This Line Output : set)
   sets.clear()
   print(sets)  (This Line Output : {})
   type(sets)  (This Line Output : set)
   

So, This are 2 ways to create empty Set.

If your application is a Java EE application running on Oracle WebLogic as the application server, a possible cause for this issue is the Statement Cache Size setting in WebLogic.

If the Statement Cache Size setting for a particular data source is about equal to, or greater than, the Oracle database maximum open cursor count setting, then all of the open cursors can be consumed by cached SQL statements that are held open by WebLogic, resulting in the ORA-01000 error.

To address this, reduce the Statement Cache Size setting for each WebLogic datasource that points to the Oracle database to be significantly less than the maximum cursor count setting on the database.

In the WebLogic 10 Admin Console, the Statement Cache Size setting for each data source can be found at Services (left nav) > Data Sources > (individual data source) > Connection Pool tab.

I had the same problem with an Angular 9.

In my case, I changed the angular.json file from

"aot": true

To

"aot": false

It works for me.

Most likely it means that the open didn't fail.

When Perl opens a file, it checks whether or not the file is a TTY (so that it can answer the -T $fh filetest operator) by issuing the TCGETS ioctl against it. If the file is a regular file and not a tty, the ioctl fails and sets errno to ENOTTY (string value: "Inappropriate ioctl for device"). As ysth says, the most common reason for seeing an unexpected value in $! is checking it when it's not valid -- that is, anywhere other than immediately after a syscall failed, so testing the result codes of your operations is critically important.

If open actually did return false for you, and you found ENOTTY in $! then I would consider this a small bug (giving a useless value of $!) but I would also be very curious as to how it happened. Code and/or truss output would be nifty.

Others have suggested IN, this is fine. You can also use a range:

DELETE from tablename where id<254 and id>3;

If the ids to delete are contiguous.

try this

import tensorflow as tf

tf.compat.v1.disable_eager_execution()

hello = tf.constant('Hello, TensorFlow!')

sess = tf.compat.v1.Session()

print(sess.run(hello))

Use preg_replace() and instead of [ \t\n\r] use \s:

$output = preg_replace('!\s+!', ' ', $input);

From Regular Expression Basic Syntax Reference:

\d, \w and \s

Shorthand character classes matching digits, word characters (letters, digits, and underscores), and whitespace (spaces, tabs, and line breaks). Can be used inside and outside character classes.

By the way why don't you use XML data insertion through Stored Procedure?

Here is the link to do that... Inserting Bulk Data through XML-Stored Procedure

Prior to version 1.14, wget timeout arguments were not adhered to if downloading over https due to a bug.

In Mercurial you use hg log --keyword to search for keywords in the commit messages and hg log --user to search for a particular user. See hg help log for other ways to limit the log.

Good post, the line

props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");

is mandatory if the SMTP server uses SSL Authentication, like the GMail SMTP server does. However if the server uses Plaintext Authentication over TLS, it should not be present, because Java Mail will complain about the initial connection being plaintext.

Also make sure you are using the latest version of Java Mail. Recently I used some old Java Mail jars from a previous project and could not make the code work, because the login process was failing. After I have upgraded to the latest version of Java Mail, the reason of the error became clear: it was a javax.net.ssl.SSLHandshakeException, which was not thrown up in the old version of the lib.

I prefer another approach if you are using mongo shell:

First as the another answers: use my_database_name then:

db.getCollectionNames().map( (name) => ({[name]: db[name].find().toArray().length}) )

This query will show you something like this:

[
        {
                "agreements" : 60
        },
        {
                "libraries" : 45
        },
        {
                "templates" : 9
        },
        {
                "users" : 19
        }
]

You can use similar approach with db.getCollectionInfos() it is pretty useful if you have so much data & helpful as well.

You can try : go to edit>preferencec>type.. select type > choose text engine options select east asian. Restart photoshop. Create new peroject. Try text tool again.

(if you want to use your project created with other text engine type) copy /paste all layers to new project.

If you can switch the ENGINE and use MyISAM instead of InnoDB, that should help:

ENGINE=MyISAM

There are two caveats with MyISAM (arguably more):

1. You can't use transactions.
2. You can't use foreign key constraints.

Answer (in Modern ECMAScript)

list.sort((a, b) => (a.attr > b.attr) - (a.attr < b.attr))

Or

list.sort((a, b) => +(a.attr > b.attr) || -(a.attr < b.attr))

Description

Casting a boolean value to a number yields the following:

• true -> 1
• false -> 0

Consider three possible patterns:

• x is larger than y: (x > y) - (y < x) -> 1 - 0 -> 1
• x is equal to y: (x > y) - (y < x) -> 0 - 0 -> 0
• x is smaller than y: (x > y) - (y < x) -> 0 - 1 -> -1

(Alternative)

• x is larger than y: +(x > y) || -(x < y) -> 1 || 0 -> 1
• x is equal to y: +(x > y) || -(x < y) -> 0 || 0 -> 0
• x is smaller than y: +(x > y) || -(x < y) -> 0 || -1 -> -1

So these logics are equivalent to typical sort comparator functions.

if (x == y) {
    return 0;
}
return x > y ? 1 : -1;

The good news is a transaction in SQL Server can span multiple batches (each exec is treated as a separate batch.)

You can wrap your EXEC statements in a BEGIN TRANSACTION and COMMIT but you'll need to go a step further and rollback if any errors occur.

Ideally you'd want something like this:

BEGIN TRY
    BEGIN TRANSACTION 
        exec( @sqlHeader)
        exec(@sqlTotals)
        exec(@sqlLine)
    COMMIT
END TRY
BEGIN CATCH

    IF @@TRANCOUNT > 0
        ROLLBACK
END CATCH

The BEGIN TRANSACTION and COMMIT I believe you are already familiar with. The BEGIN TRY and BEGIN CATCH blocks are basically there to catch and handle any errors that occur. If any of your EXEC statements raise an error, the code execution will jump to the CATCH block.

Your existing SQL building code should be outside the transaction (above) as you always want to keep your transactions as short as possible.

Working jsFiddle

Please use .size() function instead of .length and also specify li tag in selector.

Change your code like.

if ( $('#menu ul li').size() > 1 ) {

it "should call 'bar' with appropriate arguments" do
  expect(subject).to receive(:bar).with("an argument I want")
  subject.foo
end

Chr(10) is the Line Feed character and Chr(13) is the Carriage Return character.

You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.

Historically, Line Feed would move down a line but not return to column 1:

This  
    is  
        a  
            test.

Similarly Carriage Return would return to column 1 but not move down a line:

This  
is  
a  
test.

Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.

Here's what I did:

var timestamp = moment.unix({{ time }});
var utcOffset = moment().utcOffset();
var local_time = timestamp.add(utcOffset, "minutes");
var dateString = local_time.fromNow();

Where {{ time }} is the utc timestamp.

For Windows 10 using either VSCode or PyCharm with Python 3.7.4 - make sure Tk is ticked in the install. I tried import tkinter as xyz with upper/lower t and k's and all variants without luck.

What works is:

import tkinter
import _tkinter
tkinter._test()

An example in action:

import tkinter
import _tkinter

HEIGHT = 700
WIDTH = 800

root = tkinter.Tk()

canvas = tkinter.Canvas(root, height = HEIGHT, width=WIDTH)
canvas.pack()

frame = tkinter.Frame(root, bg='red')
frame.pack()

root.mainloop()

In addition to all the comments, I thought I might add some code on how to use java.util.Date, java.util.Calendar and java.util.GregorianCalendar according to the javadoc.

//Initialize your Date however you like it.
Date date = new Date();
Calendar calendar = new GregorianCalendar();
calendar.setTime(date);
int year = calendar.get(Calendar.YEAR);
//Add one to month {0 - 11}
int month = calendar.get(Calendar.MONTH) + 1;
int day = calendar.get(Calendar.DAY_OF_MONTH);

They are both correct. Personally I prefer your approach better for its verbosity but it's really down to personal preference.

Off hand, running if($_POST) would not throw an error - the $_POST array exists regardless if the request was sent with POST headers. An empty array is cast to false in a boolean check.

Remember - if you set the buttons to vbOkOnly - it will always return 1.

So you can't decide if a user clicked on the close or the OK button. You just have to add a vbOk option.

We have an app in Google Play and the App Store that will scan barcodes into a web site. The app is called Scan to Web. http://berrywing.com/scantoweb.html

You can even embed a link or button to start the scanner yourself within your web page.

<a href="bwstw://startscanner">Link to start scanner</a>

The developer documentation website for the app covers how to use the app and use JavaScript for processing the barcode scan. http://berrywing.com/scantoweb/#htmlscanbutton

What I did is first check what are the running processes by

SELECT * FROM pg_stat_activity WHERE state = 'active';

Find the process you want to kill, then type:

SELECT pg_cancel_backend(<pid of the process>)

This basically "starts" a request to terminate gracefully, which may be satisfied after some time, though the query comes back immediately.

If the process cannot be killed, try:

SELECT pg_terminate_backend(<pid of the process>)

I think there is no way to find out whether a dynamic variable has a certain member without trying to access it, unless you re-implemented the way dynamic binding is handled in the C# compiler. Which would probably include a lot of guessing, because it is implementation-defined, according to the C# specification.

So you should actually try to access the member and catch an exception, if it fails:

dynamic myVariable = GetDataThatLooksVerySimilarButNotTheSame();

try
{
    var x = myVariable.MyProperty;
    // do stuff with x
}
catch (RuntimeBinderException)
{
    //  MyProperty doesn't exist
} 

Something like:

SELECT id, email, IF(active = 1, 'enabled', 'disabled') AS account_status FROM users

This allows you to make operations and show it as columns.

EDIT:

you can also use joins and show operations as columns:

SELECT u.id, e.email, IF(c.id IS NULL, 'no selected', c.name) AS country
FROM users u LEFT JOIN countries c ON u.country_id = c.id

For Spring Boot RestTemplate:

• add org.apache.httpcomponents.httpcore dependency

• use NoopHostnameVerifier for SSL factory:

  SSLContext sslContext = new SSLContextBuilder()
          .loadTrustMaterial(new URL("file:pathToServerKeyStore"), storePassword)
  //        .loadKeyMaterial(new URL("file:pathToClientKeyStore"), storePassword, storePassword)
          .build();
  SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(sslContext, NoopHostnameVerifier.INSTANCE);
  CloseableHttpClient client = HttpClients.custom().setSSLSocketFactory(socketFactory).build();
  HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(client);
  RestTemplate restTemplate = new RestTemplate(factory);
  

lst_col = 'samples'

r = pd.DataFrame({
      col:np.repeat(df[col].values, df[lst_col].str.len())
      for col in df.columns.drop(lst_col)}
    ).assign(**{lst_col:np.concatenate(df[lst_col].values)})[df.columns]

Result:

PS here you may find a bit more generic solution

UPDATE: some explanations: IMO the easiest way to understand this code is to try to execute it step-by-step:

in the following line we are repeating values in one column N times where N - is the length of the corresponding list:

In [10]: np.repeat(df['trial_num'].values, df[lst_col].str.len())
Out[10]: array([1, 1, 1, 2, 2, 2, 3, 3, 3, 1, 1, 1, 2, 2, 2, 3, 3, 3], dtype=int64)

this can be generalized for all columns, containing scalar values:

In [11]: pd.DataFrame({
    ...:           col:np.repeat(df[col].values, df[lst_col].str.len())
    ...:           for col in df.columns.drop(lst_col)}
    ...:         )
Out[11]:
    trial_num  subject
0           1        1
1           1        1
2           1        1
3           2        1
4           2        1
5           2        1
6           3        1
..        ...      ...
11          1        2
12          2        2
13          2        2
14          2        2
15          3        2
16          3        2
17          3        2

[18 rows x 2 columns]

using np.concatenate() we can flatten all values in the list column (samples) and get a 1D vector:

In [12]: np.concatenate(df[lst_col].values)
Out[12]: array([-1.04, -0.58, -1.32,  0.82, -0.59, -0.34,  0.25,  2.09,  0.12,  0.83, -0.88,  0.68,  0.55, -0.56,  0.65, -0.04,  0.36, -0.31])

putting all this together:

In [13]: pd.DataFrame({
    ...:           col:np.repeat(df[col].values, df[lst_col].str.len())
    ...:           for col in df.columns.drop(lst_col)}
    ...:         ).assign(**{lst_col:np.concatenate(df[lst_col].values)})
Out[13]:
    trial_num  subject  samples
0           1        1    -1.04
1           1        1    -0.58
2           1        1    -1.32
3           2        1     0.82
4           2        1    -0.59
5           2        1    -0.34
6           3        1     0.25
..        ...      ...      ...
11          1        2     0.68
12          2        2     0.55
13          2        2    -0.56
14          2        2     0.65
15          3        2    -0.04
16          3        2     0.36
17          3        2    -0.31

[18 rows x 3 columns]

using pd.DataFrame()[df.columns] will guarantee that we are selecting columns in the original order...

Your format specifier is incorrect. From the printf() man page on my machine:

0 A zero '0' character indicating that zero-padding should be used rather than blank-padding. A '-' overrides a '0' if both are used;

Field Width: An optional digit string specifying a field width; if the output string has fewer characters than the field width it will be blank-padded on the left (or right, if the left-adjustment indicator has been given) to make up the field width (note that a leading zero is a flag, but an embedded zero is part of a field width);

Precision: An optional period, '.', followed by an optional digit string giving a precision which specifies the number of digits to appear after the decimal point, for e and f formats, or the maximum number of characters to be printed from a string; if the digit string is missing, the precision is treated as zero;

For your case, your format would be %09.3f:

#include <stdio.h>

int main(int argc, char **argv)
{
  printf("%09.3f\n", 4917.24);
  return 0;
}

Output:

$ make testapp
cc     testapp.c   -o testapp
$ ./testapp 
04917.240

Note that this answer is conditional on your embedded system having a printf() implementation that is standard-compliant for these details - many embedded environments do not have such an implementation.

First check your listener is on or off. Go to net manager then Local -> service naming -> orcl. Then change your HOST NAME and put your PC name. Now go to LISTENER and change the HOST and put your PC name.

You can put this inside your jquery code or it can stand alone:

window.onload = prep;

function prep(){
document.getElementById('somediv').onclick = function(){
document.getElementById('inputField').value ='';
  }
}

Usefull fallback here: https://developer.mozilla.org/en-US/docs/Web/Events/MozOrientation

function orientationhandler(evt){


  // For FF3.6+
  if (!evt.gamma && !evt.beta) {
    evt.gamma = -(evt.x * (180 / Math.PI));
    evt.beta = -(evt.y * (180 / Math.PI));
  }

  // use evt.gamma, evt.beta, and evt.alpha 
  // according to dev.w3.org/geo/api/spec-source-orientation


}

window.addEventListener('deviceorientation',  orientationhandler, false);
window.addEventListener('MozOrientation',     orientationhandler, false);

If you want to import a specific function or class from a module, you can do this:

import importlib
import sys
importlib.reload(sys.modules['my_module'])
from my_module import my_function

Style is an attribute so css won't work for it.U can use attr

Change:

$('.handle').css({'style':'left: 300px'});

T0:

$('.handle').attr('style','left: 300px');//Use `,` Comma instead of `:` colon

You have to enable null value for your date variable :

 public Nullable<DateTime> MyDate{ get; set; }

Try to remove node_modules rm -rf node_modules and package-lock.json rm -rf package-lock.json, after that run npm install.

For PHP 7.x

sudo apt-get install php-zip

For PHP 5.x

sudo apt-get install php5.x-zip
// (for example sudo apt-get install php5.6-zip)

And then restart the Apache server

sudo service apache2 restart

Set the method attribute to POST because file content can't be put inside a URL parameter using a form.

Set the value of enctype to multipart/form-data because the data will be split into multiple parts, one for each file plus one for the text of the form body that may be sent with them.

start did not work for me.

I used:

firefox http://www.stackoverflow.com

or

chrome http://www.stackoverflow.com

Obviously not great for distributing it, but if you're using it for a specific machine, it should work fine.

You can get the 'outer-html' by cloning the element, adding it to an empty,'offstage' container, and reading the container's innerHTML.

This example takes an optional second parameter.

Call document.getHTML(element, true) to include the element's descendents.

document.getHTML= function(who, deep){
    if(!who || !who.tagName) return '';
    var txt, ax, el= document.createElement("div");
    el.appendChild(who.cloneNode(false));
    txt= el.innerHTML;
    if(deep){
        ax= txt.indexOf('>')+1;
        txt= txt.substring(0, ax)+who.innerHTML+ txt.substring(ax);
    }
    el= null;
    return txt;
}

You just need to add a From: header. By default there is none.

echo "Test" | mail -a "From: Someone <[email protected]>" [email protected]

You can add any custom headers using -a:

echo "Test" | mail -a "From: Someone <[email protected]>" \
                   -a "Subject: This is a test" \
                   -a "X-Custom-Header: yes" [email protected]

This is probably an edge case, but every time I've got this specific error it is because I've recently mapped a drive in Windows, and powershell cannot find it.

A computer restart (of all things) fixes the error for me, as powershell can now pick up the newly mapped drive. Just make sure you connect to the mapped drive BEFORE opening the github client.

Configure XCode project settings, it can solve your problem.

<add key="ValidationSettings:UnobtrusiveValidationMode" value="WebForms" />

this line was not in my WebConfig so : I simple solved this by downgrading targetting .Net version to 4.0 :)

As for the workaround (e.g. Windows slave), define the following environment variable in global properties:

GIT_SSH_COMMAND="ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no"

Note: If you don't see the option, you probably need EnvInject plugin for it.

With absolute or relative positioning, you can do all sorts of overlapping. You've probably want the logo to be styled as such:

div#logo {
  position: absolute;
  left: 100px; // or whatever
}

Note: absolute position has its eccentricities. You'll probably have to experiment a little, but it shouldn't be too hard to do what you want.

Replace audio

ffmpeg -i video.mp4 -i audio.wav -map 0:v -map 1:a -c:v copy -shortest output.mp4

• The -map option allows you to manually select streams / tracks. See FFmpeg Wiki: Map for more info.
• This example uses -c:v copy to stream copy (mux) the video. No re-encoding of the video occurs. Quality is preserved and the process is fast.
  • If your input audio format is compatible with the output format then change -c:v copy to -c copy to stream copy both the video and audio.
  • If you want to re-encode video and audio then remove -c:v copy / -c copy.
• The -shortest option will make the output the same duration as the shortest input.

Add audio

ffmpeg -i video.mkv -i audio.mp3 -map 0 -map 1:a -c:v copy -shortest output.mkv

• The -map option allows you to manually select streams / tracks. See FFmpeg Wiki: Map for more info.
• This example uses -c:v copy to stream copy (mux) the video. No re-encoding of the video occurs. Quality is preserved and the process is fast.
  • If your input audio format is compatible with the output format then change -c:v copy to -c copy to stream copy both the video and audio.
  • If you want to re-encode video and audio then remove -c:v copy / -c copy.
• The -shortest option will make the output the same duration as the shortest input.

Mixing/combining two audio inputs into one

Use video from video.mkv. Mix audio from video.mkv and audio.m4a using the amerge filter:

ffmpeg -i video.mkv -i audio.m4a -filter_complex "[0:a][1:a]amerge=inputs=2[a]" -map 0:v -map "[a]" -c:v copy -ac 2 -shortest output.mkv

See FFmpeg Wiki: Audio Channels for more info.

Generate silent audio

You can use the anullsrc filter to make a silent audio stream. The filter allows you to choose the desired channel layout (mono, stereo, 5.1, etc) and the sample rate.

ffmpeg -i video.mp4 -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=44100 \
-c:v copy -shortest output.mp4

hasOwnProperty is a normal JavaScript function that takes a string argument.

When you call shape1.hasOwnProperty(name) you are passing it the value of the name variable (which doesn't exist), just as it would if you wrote alert(name).

You need to call hasOwnProperty with a string containing name, like this: shape1.hasOwnProperty("name").

String original = "hello world";
byte[] utf8Bytes = original.getBytes("UTF-8");

The other answers so far create new commits that undo what is in older commits. It is possible to go back and "change history" as it were, but this can be a bit dangerous. You should only do this if the commit you're changing has not been pushed to other repositories.

The command you're looking for is git rebase --interactive

If you want to change HEAD~3, the command you want to issue is git rebase --interactive HEAD~4. This will open a text editor and allow you to specify which commits you want to change.

Practice on a different repository before you try this with something important. The man pages should give you all the rest of the information you need.

A more pythonic way, without using set is as follows:

lst = [1, 2, 3, 4]
lst.append(3) if 3 not in lst else lst

In your comment in response to John, you suggest that you want the keys and values of the dictionary, not just the values.

PEP 256 suggests this for sorting a dictionary by values.

import operator
sorted(d.iteritems(), key=operator.itemgetter(1))

If you want descending order, do this

sorted(d.iteritems(), key=itemgetter(1), reverse=True)

I found an add-on for Brackets.io that uses auto-indent called Indentator.
It uses shortcut keys Ctrl + Alt + I

I have also seen

if [ "x$variable" = "x" ]; then ...

which is obviously very robust and shell independent.

Also, there is a difference between "empty" and "unset". See How to tell if a string is not defined in a Bash shell script.

Use the CATALINA_OPTS environment variable.

This syntax has changed with the newer Apache HTTPd server, please see upgrade to apache 2.4 doc for full details.

2.2 configuration syntax was

Deny from all

2.4 configuration now is

Require all denied

Thus, this 2.2 syntax

order deny,allow
deny from all
allow from 127.0.0.1

Would ne now written

Require local

Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.

First the actual accounts:

• LocalService account (preferred)

  A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.

  • Name: NT AUTHORITY\LocalService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the LocalService user account
  • has minimal privileges on the local computer
  • presents anonymous credentials on the network
  • SID: S-1-5-19
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-19)

   

• NetworkService account

  Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).

  • NT AUTHORITY\NetworkService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the NetworkService user account
  • has minimal privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers
  • SID: S-1-5-20
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-20)
  • If trying to schedule a task using it, enter NETWORK SERVICE into the Select User or Group dialog

   

• LocalSystem account (dangerous, don't use!)

  Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)

  • Name: .\LocalSystem (can also use LocalSystem or ComputerName\LocalSystem)
  • the account has no password (any password information you provide is ignored)
  • SID: S-1-5-18
  • does not have any profile of its own (HKCU represents the default user)
  • has extensive privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers

   

Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService can still access the internet.

The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).

It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.

In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).

In Windows Server 2003 you cannot run a scheduled task as

• NT_AUTHORITY\LocalService (aka the Local Service account), or
• NT AUTHORITY\NetworkService (aka the Network Service account).

That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.

A service running as NetworkService presents the machine credentials on the network. This means that if your computer was called mango, it would present as the machine account MANGO$:

I know this is an old question, and most people have replied with good answers. But for reference and hopefully saving somebody else's time. Check if your function:

$(document).ready(function(){}

is being called after you have loaded the JQuery library

You could go into the designer of the web form and change the "webcontrols" to be "public" instead of "protected" but I'm not sure how safe that is. I prefer to make hidden inputs and have some jQuery set the values into those hidden inputs, then create public properties in the web form's class (code behind), and access the values that way.

On your own system, try

install.packages("foo", dependencies=...)

with the dependencies= argument is documented as

dependencies: logical indicating to also install uninstalled packages
      which these packages depend on/link to/import/suggest (and so
      on recursively).  Not used if ‘repos = NULL’.  Can also be a
      character vector, a subset of ‘c("Depends", "Imports",
      "LinkingTo", "Suggests", "Enhances")’.

      Only supported if ‘lib’ is of length one (or missing), so it
      is unambiguous where to install the dependent packages.  If
      this is not the case it is ignored, with a warning.

      The default, ‘NA’, means ‘c("Depends", "Imports",
      "LinkingTo")’.

      ‘TRUE’ means (as from R 2.15.0) to use ‘c("Depends",
      "Imports", "LinkingTo", "Suggests")’ for ‘pkgs’ and
      ‘c("Depends", "Imports", "LinkingTo")’ for added
      dependencies: this installs all the packages needed to run
      ‘pkgs’, their examples, tests and vignettes (if the package
      author specified them correctly).

so you probably want a value TRUE.

In your package, list what is needed in Depends:, see the Writing R Extensions manual which is pretty clear on this.

In Windows nslookup the command is

ls -d somedomain.com > outfile.txt

which stores the subdomain list in outfile.txt

few domains these days allow this

There is nothing you can do on your end (client side). You can not enable crossDomain calls yourself, the source (dailymotion.com) needs to have CORS enabled for this to work.

The only thing you can really do is to create a server side proxy script which does this for you. Are you using any server side scripts in your project? PHP, Python, ASP.NET etc? If so, you could create a server side "proxy" script which makes the HTTP call to dailymotion and returns the response. Then you call that script from your Javascript code, since that server side script is on the same domain as your script code, CORS will not be a problem.

You may also get this error if you have a name clash of a view and a module. I've got the error when i distribute my view files under views folder, /views/view1.py, /views/view2.py and imported some model named table.py in view2.py which happened to be a name of a view in view1.py. So naming the view functions as v_table(request,id) helped.

I know this is weird but when I changed GetMapping to PostMapping for both client and server side the error disappeared.

Both client and server are Spring boot projects.

cat ~/.ssh/id_rsa.pub or cat ~/.ssh/id_dsa.pub

You can list all the public keys you have by doing:

$ ls ~/.ssh/*.pub

I have written a Java class RawConsoleInput that uses JNA to call operating system functions of Windows and Unix/Linux.

• On Windows it uses _kbhit() and _getwch() from msvcrt.dll.
• On Unix it uses tcsetattr() to switch the console to non-canonical mode, System.in.available() to check whether data is available and System.in.read() to read bytes from the console. A CharsetDecoder is used to convert bytes to characters.

It supports non-blocking input and mixing raw mode and normal line mode input.

The getRequestURL() omits the port when it is 80 while the scheme is http, or when it is 443 while the scheme is https.

So, just use getRequestURL() if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:

StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
    requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();

Use LINQ: Access to dictionary for the key and change the value

Dictionary<string, int> dict = new Dictionary<string, int>();
dict = dict.ToDictionary(kvp => kvp.Key, kvp => kvp.Value + 1);

Replace

 var myNewString = myOldString.replace ("username," visitorName);

with

 var myNewString = myOldString.replace("username", visitorName);

For increasing execution time and file size, you need to mention below values in your .htaccess file. It will work.

php_value upload_max_filesize 80M
php_value post_max_size 80M
php_value max_input_time 18000
php_value max_execution_time 18000

If you have this error in console ([$injector:nomod], MINERR_ASSET:22), make sure you are not including your application code before loading AngularJS

I was doing that and once I fixed the order, the error went away.

You just need to keep track of a max value like this:

int maxValue = 0;

Then as you iterate through the numbers, keep setting the maxValue to the next value if it is greater than the maxValue:

if (value > maxValue) {
    maxValue = value;
}

Repeat in the opposite direction for minValue.

You can achieve that using DATE_FORMAT() (click the link for more other formats)

SELECT DATE_FORMAT(colName, '%Y-%m-%d') DATEONLY, 
       DATE_FORMAT(colName,'%H:%i:%s') TIMEONLY

for i in range (1,10):
    string="string"+str(i)

To get string0, string1 ..... string10, you could do like

['string0', 'string1', 'string2', 'string3', 'string4', 'string5', 'string6', 'string7', 'string8', 'string9', 'string10']

If Foo is the class enclose this method

}

then

new Foo().myNumbers();

$JAVA_HOME/bin/java -version says 'Permission Denied'

to see why you cannot access or run this program,.

};

Normally the ON clause comes from the mapping's join columns, but the JPA 2.1 draft allows for additional conditions in a new ON clause.

A combination of peoples post gave me the date and the time for excel conversion. I did return it as a string

def xldate_to_datetime(xldate):
  tempDate = datetime.datetime(1900, 1, 1)
  deltaDays = datetime.timedelta(days=int(xldate))
  secs = (int((xldate%1)*86400)-60)
  detlaSeconds = datetime.timedelta(seconds=secs)
  TheTime = (tempDate + deltaDays + detlaSeconds )
  return TheTime.strftime("%Y-%m-%d %H:%M:%S")

If you need to convert the dictionary to binary, you need to convert it to a string (JSON) as described in the previous answer, then you can convert it to binary.

For example:

my_dict = {'key' : [1,2,3]}

import json
def dict_to_binary(the_dict):
    str = json.dumps(the_dict)
    binary = ' '.join(format(ord(letter), 'b') for letter in str)
    return binary


def binary_to_dict(the_binary):
    jsn = ''.join(chr(int(x, 2)) for x in the_binary.split())
    d = json.loads(jsn)  
    return d

bin = dict_to_binary(my_dict)
print bin

dct = binary_to_dict(bin)
print dct

will give the output

1111011 100010 1101011 100010 111010 100000 1011011 110001 101100 100000 110010 101100 100000 110011 1011101 1111101

{u'key': [1, 2, 3]}

For me the issue turned out to be I was using es6's right arrow functions => as opposed to function ().

Replacing => with function () resolved for me.

I had assumed it was a jQuery issue.

cURL is disabled for most hosting control panels for security reasons, but it's required for a lot of php applications. It's not unusual for a client to request it. Since the risk of enabling cURL is minimal, you are probably better off enabling it than losing a customer. It's simply a utility that helps php scripts fetch things using standard Internet URLs.

To enable cURL, you will remove curl_exec from the "disabled list" in the control panel php advanced settings. You will also find a disabled list in the various php.ini files; look in /etc/php.ini and other paths that might exist for your control panel. You will need to restart Apache to make the change take effect.

service httpd restart

To confirm whether cURL is enabled or disabled, create a file somewhere in your system and paste the following contents.

<?php
echo '<pre>';
var_dump(curl_version());
echo '</pre>';
?>

Save the file as testcurl.php and then run it as a php script.

php testcurl.php

If cURL is disabled you will see this error.

Fatal error: Call to undefined function curl_version() in testcurl.php on line 2

If cURL is enabled you will see a long list of attributes, like this.

I've had a similar issue with this error. In my case, I was entering the incorrect password for the Keystore.

I changed the password for the Keystore to match what I was entering (I didn't want to change the password I was entering), but it still gave the same error.

keytool -storepasswd -keystore keystore.jks

Problem was that I also needed to change the Key's password within the Keystore.

When I initially created the Keystore, the Key was created with the same password as the Keystore (I accepted this default option). So I had to also change the Key's password as follows:

keytool -keypasswd  -alias my.alias -keystore keystore.jks

It may not sound a good idea but i used java and used simple TCP/IP socket programming to connect to a telnet server and exchange communication. ANd it works perfectly if you know the protocol implemented. For SSH etc, it might be tough unless you know how to do the handshake etc, but simple telnet works like a treat.

Another way i tried, was using external process in java System.exec() etc, and then let the windows built in telnet do the job for you and you just send and receive data to the local system process.

Deleting files and folders

If you want to delete an item from the repository, but keep it locally as an unversioned file/folder, use Extended Context Menu ? Delete (keep local). You have to hold the Shift key while right clicking on the item in the explorer list pane (right pane) in order to see this in the extended context menu.

Delete completely:
right mouse click ? Menu ? Delete

Delete & Keep local:
Shift + right mouse click ? Menu ? Delete

On Mac, if you have multiple GitHub logins and are not using SSH, force the correct login by using:

git remote set-url origin https://[email protected]/username/repo-name.git

This also works if you're having issues pushing to a private repository.

This answer is for "One Man" Team to solve this problem quickly without reading through too many information about "Team"

Step 1) Go to web browser, open your developer account. Go to Certificates, Identifiers & Profiles. Select Certificates / Production. You will see the certificate that was missing private key listed there. Click Revoke. And follow the instructions to remove this certificate. Step 2) That's it! go back to Xcode to Validate you app. It will now ask you to generate a new certificate. Now you happily uploading your apps.

Below I have put together everything I learned about Starting/Stopping a Windows Service from a non-Admin user account, if anyone needs to know.

Primarily, there are two ways in which to Start / Stop a Windows Service. 1. Directly accessing the service through logon Windows user account. 2. Accessing the service through IIS using Network Service account.

Command line command to start / stop services:

C:/> net start <SERVICE_NAME>
C:/> net stop <SERVICE_NAME>

C# Code to start / stop services:

ServiceController service = new ServiceController(SERVICE_NAME);

//Start the service
if (service.Status == ServiceControllerStatus.Stopped)
{
      service.Start();
      service.WaitForStatus(ServiceControllerStatus.Running, TimeSpan.FromSeconds(10.0));
}

//Stop the service
if (service.Status == ServiceControllerStatus.Running)
{
      service.Stop();
      service.WaitForStatus(ServiceControllerStatus.Stopped, TimeSpan.FromSeconds(10.0));
}

Note 1: When accessing the service through IIS, create a Visual Studio C# ASP.NET Web Application and put the code in there. Deploy the WebService to IIS Root Folder (C:\inetpub\wwwroot\) and you're good to go. Access it by the url http:///.

1. Direct Access Method

If the Windows User Account from which either you give the command or run the code is a non-Admin account, then you need to set the privileges to that particular user account so it has the ability to start and stop Windows Services. This is how you do it. Login to an Administrator account on the computer which has the non-Admin account from which you want to Start/Stop the service. Open up the command prompt and give the following command:

C:/>sc sdshow <SERVICE_NAME>

Output of this will be something like this:

D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;IU)(A;;CCLCSWLOCRRC;;;SU)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD)

It lists all the permissions each User / Group on this computer has with regards to .

A description of one part of above command is as follows:

    D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)

It has the default owner, default group, and it has the Security descriptor control flags (A;;CCLCSWRPWPDTLOCRRC;;;SY):

ace_type - "A": ACCESS_ALLOWED_ACE_TYPE,
ace_flags - n/a,
rights - CCLCSWRPWPDTLOCRRC,  please refer to the Access Rights and Access Masks and Directory Services Access Rights
CC: ADS_RIGHT_DS_CREATE_CHILD - Create a child DS object.
LC: ADS_RIGHT_ACTRL_DS_LIST - Enumerate a DS object.
SW: ADS_RIGHT_DS_SELF - Access allowed only after validated rights checks supported by the object are performed. This flag can be used alone to perform all validated rights checks of the object or it can be combined with an identifier of a specific validated right to perform only that check.
RP: ADS_RIGHT_DS_READ_PROP - Read the properties of a DS object.
WP: ADS_RIGHT_DS_WRITE_PROP - Write properties for a DS object.
DT: ADS_RIGHT_DS_DELETE_TREE - Delete a tree of DS objects.
LO: ADS_RIGHT_DS_LIST_OBJECT - List a tree of DS objects.
CR: ADS_RIGHT_DS_CONTROL_ACCESS - Access allowed only after extended rights checks supported by the object are performed. This flag can be used alone to perform all extended rights checks on the object or it can be combined with an identifier of a specific extended right to perform only that check.
RC: READ_CONTROL - The right to read the information in the object's security descriptor, not including the information in the system access control list (SACL). (This is a Standard Access Right, please read more http://msdn.microsoft.com/en-us/library/aa379607(VS.85).aspx)
object_guid - n/a,
inherit_object_guid - n/a,
account_sid - "SY": Local system. The corresponding RID is SECURITY_LOCAL_SYSTEM_RID.

Now what we need to do is to set the appropriate permissions to Start/Stop Windows Services to the groups or users we want. In this case we need the current non-Admin user be able to Start/Stop the service so we are going to set the permissions to that user. To do that, we need the SID of that particular Windows User Account. To obtain it, open up the Registry (Start > regedit) and locate the following registry key.

LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

Under that there is a seperate Key for each an every user account in this computer, and the key name is the SID of each account. SID are usually of the format S-1-5-21-2103278432-2794320136-1883075150-1000. Click on each Key, and you will see on the pane to the right a list of values for each Key. Locate "ProfileImagePath", and by it's value you can find the User Name that SID belongs to. For instance, if the user name of the account is SACH, then the value of "ProfileImagePath" will be something like "C:\Users\Sach". So note down the SID of the user account you want to set the permissions to.

Note2: Here a simple C# code sample which can be used to obtain a list of said Keys and it's values.

//LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList RegistryKey
RegistryKey profileList = Registry.LocalMachine.OpenSubKey(keyName);

//Get a list of SID corresponding to each account on the computer
string[] sidList = profileList.GetSubKeyNames();

foreach (string sid in sidList)
{
    //Based on above names, get 'Registry Keys' corresponding to each SID
    RegistryKey profile = Registry.LocalMachine.OpenSubKey(Path.Combine(keyName, sid));

    //SID
    string strSID = sid;
    //UserName which is represented by above SID    
    string strUserName = (string)profile.GetValue("ProfileImagePath");
}

Now that we have the SID of the user account we want to set the permissions to, let's get down to it. Let's assume the SID of the user account is S-1-5-21-2103278432-2794320136-1883075150-1000. Copy the output of the [sc sdshow ] command to a text editor. It will look like this:

D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;IU)(A;;CCLCSWLOCRRC;;;SU)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD)

Now, copy the (A;;CCLCSWRPWPDTLOCRRC;;;SY) part of the above text, and paste it just before the S:(AU;... part of the text. Then change that part to look like this: (A;;RPWPCR;;;S-1-5-21-2103278432-2794320136-1883075150-1000)

Then add sc sdset at the front, and enclose the above part with quotes. Your final command should look something like the following:

sc sdset <SERVICE_NAME> "D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;IU)(A;;CCLCSWLOCRRC;;;SU)(A;;RPWPCR;;;S-1-5-21-2103278432-2794320136-1883075150-1000)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD)"

Now execute this in your command prompt, and it should give the output as follows if successful:

[SC] SetServiceObjectSecurity SUCCESS

Now we're good to go! Your non-Admin user account has been granted permissions to Start/Stop your service! Try loggin in to the user account and Start/Stop the service and it should let you do that.

2. Access through IIS Method

In this case, we need to grant the permission to the IIS user "Network Services" instead of the logon Windows user account. The procedure is the same, only the parameters of the command will be changed. Since we set the permission to "Network Services", replace SID with the string "NS" in the final sdset command we used previously. The final command should look something like this:

sc sdset <SERVICE_NAME> "D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;IU)(A;;CCLCSWLOCRRC;;;SU)(A;;RPWPCR;;;NS)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD)"

Execute it in the command prompt from an Admin user account, and voila! You have the permission to Start / Stop the service from any user account (irrespective of whether it ia an Admin account or not) using a WebMethod. Refer to Note1 to find out how to do so.

gem bootstrap-sass

bootstrap-sass is easy to drop into Rails with the asset pipeline.

In your Gemfile you need to add the bootstrap-sass gem, and ensure that the sass-rails gem is present - it is added to new Rails applications by default.

gem 'sass-rails', '>= 3.2' # sass-rails needs to be higher than 3.2 gem 'bootstrap-sass', '~> 3.0.3.0'

bundle install and restart your server to make the files available through the pipeline.

Source: http://rubydoc.info/gems/bootstrap-sass/3.0.3.0/frames

Disclosure:

• Applicable on Linux only
• Reports memory used by the current process as a whole, not individual functions within

But nice because of its simplicity:

import resource
def using(point=""):
    usage=resource.getrusage(resource.RUSAGE_SELF)
    return '''%s: usertime=%s systime=%s mem=%s mb
           '''%(point,usage[0],usage[1],
                usage[2]/1024.0 )

Just insert using("Label") where you want to see what's going on. For example

print(using("before"))
wrk = ["wasting mem"] * 1000000
print(using("after"))

>>> before: usertime=2.117053 systime=1.703466 mem=53.97265625 mb
>>> after: usertime=2.12023 systime=1.70708 mem=60.8828125 mb

Try like this

ImageButton imagetrans=(ImageButton)findViewById(R.id.ImagevieID);

imagetrans.setBackgroundColor(Color.TRANSPARENT);

OR

include this in your .xml file in res/layout

android:background="@android:color/transparent 

By default transaction propagation is REQUIRED, meaning that the same transaction will propagate from a transactional caller to transactional callee. In this case also the read-only status will propagate. E.g. if a read-only transaction will call a read-write transaction, the whole transaction will be read-only.

Could you use the Open Session in View pattern to allow lazy loading? That way your handle method does not need to be transactional at all.

When people say don't put logic in views, they're usually referring to business logic, not rendering logic. In my humble opinion, I think using @foreach in views is perfectly fine.

If you want to permanently ignore these files, a simple way to add them to .gitignore is:

1. Change to the root of the git tree.
2. git ls-files --others --exclude-standard >> .gitignore

This will enumerate all files inside untracked directories, which may or may not be what you want.

For having a trasition effect like a highlighter just to highlight the text and fade off the bg color, we used the following:

.field-error {_x000D_
    color: #f44336;_x000D_
    padding: 2px 5px;_x000D_
    position: absolute;_x000D_
    font-size: small;_x000D_
    background-color: white;_x000D_
}_x000D_
_x000D_
.highlighter {_x000D_
    animation: fadeoutBg 3s; /***Transition delay 3s fadeout is class***/_x000D_
    -moz-animation: fadeoutBg 3s; /* Firefox */_x000D_
    -webkit-animation: fadeoutBg 3s; /* Safari and Chrome */_x000D_
    -o-animation: fadeoutBg 3s; /* Opera */_x000D_
}_x000D_
_x000D_
@keyframes fadeoutBg {_x000D_
    from { background-color: lightgreen; } /** from color **/_x000D_

<div class="field-error highlighter">File name already exists.</div>

AFAIK, there is no method that does this in the framework. Even if there was support for something like this in the framework, it would essentially be doing the same thing. And that would be looking at each cell in the DataRow to see if it is empty.

This works for me:

export var jQuery: any = window["jQuery"];

Try this folowing method :

ImageIcon icon = new ImageIcon("image.png");
Image img = icon.getImage();
Image newImg = img.getScaledInstance(350, 350, java.evt.Image.SCALE_SMOOTH);
icon = new ImageIcon(img);
JOptionPane.showMessageDialog(null, "image on The frame", "Display Image", JOptionPane.INFORMATION_MESSAGE, icon);

One alternative missing from other answers is that you can go the other way around: define your method in your Controller, and then use helper_method to make it also available on views as, you know, a helper method.

For instance:

class ApplicationController < ActionController::Base

private

  def something_count
    # All other controllers that inherit from ApplicationController will be able to call `something_count`
  end
  # All views will be able to call `something_count` as well
  helper_method :something_count 

end

The direct answer to this question is:

if(rows.Any()) //prevent IndexOutOfRangeException for empty list
{
    rows.RemoveAt(rows.Count - 1);
}

However... in the specific case of this question, it makes more sense not to add the row in the first place:

Row row = new Row();
//...      

if (!row.cell[0].Equals("Something"))
{
    rows.Add(row);
}

TBH, I'd go a step further by testing "Something" against user."", and not even instantiating a Row unless the condition is satisfied, but seeing as user."" won't compile, I'll leave that as an exercise for the reader.

I prefer to hide all code complexity in my services... so, I generally use something like this:

In my events.service.ts

    async getEvents() {
        const snapchot = await this.db.collection('events').ref.get();
        return new Promise <Event[]> (resolve => {
            const v = snapchot.docs.map(x => {
                const obj = x.data();
                obj.id = x.id;
                return obj as Event;
            });
            resolve(v);
        });
    }

In my sth.page.ts

   myList: Event[];

   construct(private service: EventsService){}

   async ngOnInit() {
      this.myList = await this.service.getEvents();
   }

Enjoy :)

I have made my own solution using NSTimer and Alamofire:

import Alamofire

public class ConnectionHelper: NSObject {
    var request: Alamofire.Request?

    func isInternetConnected(completionHandler: Bool -> Void) {
        NSTimer.scheduledTimerWithTimeInterval(5.0, target: self, selector: "requestTimeout", userInfo: nil, repeats: false)

        request = Alamofire
            .request(
                Method.HEAD,
                "http://www.testurl.com"
            )
            .response { response in
                if response.3?.code == -999 {
                    completionHandler(
                        false
                    )
                } else {
                    completionHandler(
                        true
                    )
                }
        }
    }

    func requestTimeout() {
        request!.cancel()
    }
}

The NSTimer is used as a timeout, and was used due to unreliable results using the Alamofire timeout. The request should be made to a URL you trust to be reliable, such as your own server or the server that is hosting the services you depend on.

When the timer expires, the request is cancelled and the results are returned using a completion handler.

Usage:

ConnectionHelper().isInternetConnected() { internetConnected in
    if internetConnected {
        // Connected
    } else {
        // Not connected
    }
}

jQuery is about 40 times SLOWER, please do not use jQuery for that simple task.

function htmlToPlaintext(text) {
  return text ? String(text).replace(/<[^>]+>/gm, '') : '';
}

usage :

var plain_text = htmlToPlaintext( your_html );

With angular.js :

angular.module('myApp.filters', []).
  filter('htmlToPlaintext', function() {
    return function(text) {
      return  text ? String(text).replace(/<[^>]+>/gm, '') : '';
    };
  }
);

use :

<div>{{myText | htmlToPlaintext}}</div>  

The move instruction copies a value from one register to another. The li instruction loads a specific numeric value into that register.

For the specific case of zero, you can use either the constant zero or the zero register to get that:

move $s0, $zero
li   $s0, 0

There's no register that generates a value other than zero, though, so you'd have to use li if you wanted some other number, like:

li $s0, 12345678

The communication link between the driver and the data source to which the driver was attempting to connect failed before the function completed processing. So usually its a network error. This could be caused by packet drops or badly configured Firewall/Switch.

string connString = "<your connection string>";
string sql = "name of your sp";

using(SqlConnection conn = new SqlConnection(connString)) 
{
    try 
    {
        using(SqlDataAdapter da = new SqlDataAdapter()) 
        {
            da.SelectCommand = new SqlCommand(sql, conn);
            da.SelectCommand.CommandType = CommandType.StoredProcedure;

            DataSet ds = new DataSet();   
            da.Fill(ds, "result_name");

            DataTable dt = ds.Tables["result_name"];

            foreach (DataRow row in dt.Rows) {
                //manipulate your data
            }
        }    
    } 
    catch(SQLException ex) 
    {
        Console.WriteLine("SQL Error: " + ex.Message);
    }
    catch(Exception e) 
    {
        Console.WriteLine("Error: " + e.Message);
    }
}

Here's another approach:

sprintf("%02x", 10).upcase

see the documentation for sprintf here: http://www.ruby-doc.org/core/classes/Kernel.html#method-i-sprintf

To convert all float columns to int

>>> df = pd.DataFrame(np.random.rand(5, 4) * 10, columns=list('PQRS'))
>>> print(df)
...     P           Q           R           S
... 0   4.395994    0.844292    8.543430    1.933934
... 1   0.311974    9.519054    6.171577    3.859993
... 2   2.056797    0.836150    5.270513    3.224497
... 3   3.919300    8.562298    6.852941    1.415992
... 4   9.958550    9.013425    8.703142    3.588733

>>> float_col = df.select_dtypes(include=['float64']) # This will select float columns only
>>> # list(float_col.columns.values)

>>> for col in float_col.columns.values:
...     df[col] = df[col].astype('int64')

>>> print(df)
...     P   Q   R   S
... 0   4   0   8   1
... 1   0   9   6   3
... 2   2   0   5   3
... 3   3   8   6   1
... 4   9   9   8   3

As Dudley mentioned in his answer this is possible with the drop-shadow CSS filter for webkit, SVG for Firefox and DirectX filters for Internet Explorer 9-.

One step further is to inline the SVG, eliminating the extra request:

.shadowed {
    -webkit-filter: drop-shadow(12px 12px 25px rgba(0,0,0,0.5));
    filter: url("data:image/svg+xml;utf8,<svg height='0' xmlns='http://www.w3.org/2000/svg'><filter id='drop-shadow'><feGaussianBlur in='SourceAlpha' stdDeviation='4'/><feOffset dx='12' dy='12' result='offsetblur'/><feFlood flood-color='rgba(0,0,0,0.5)'/><feComposite in2='offsetblur' operator='in'/><feMerge><feMergeNode/><feMergeNode in='SourceGraphic'/></feMerge></filter></svg>#drop-shadow");
    -ms-filter: "progid:DXImageTransform.Microsoft.Dropshadow(OffX=12, OffY=12, Color='#444')";
    filter: "progid:DXImageTransform.Microsoft.Dropshadow(OffX=12, OffY=12, Color='#444')";
}

try the following as there will be no varchar conversion

SELECT Subject, CAST(DeliveryDate AS DATE)
from Email_Administration 
where MerchantId =@ MerchantID

As others pointed out, this message is coming from your shell prompt. The problem is that in a freshly created repository HEAD (.git/HEAD) points to a ref that doesn't exist yet.

% git init test
Initialized empty shared Git repository in /Users/jhelwig/tmp/test/.git/
% cd test
% cat .git/HEAD
ref: refs/heads/master
% ls -l .git/refs/heads
total 0
% git rev-parse HEAD
HEAD
fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions

It looks like rev-parse is being used without sufficient error checking before-hand. After the first commit has been created .git/refs/heads looks a bit different and git rev-parse HEAD will no longer fail.

% ls -l .git/refs/heads
total 4
-rw------- 1 jhelwig staff 41 Oct 14 16:07 master
% git rev-parse HEAD

In the function that updates the Git information for the rest of my shell prompt (heavily modified version of wunjo prompt theme for ZSH), I have the following to get around this:

zgit_info_update() {
    zgit_info=()

    local gitdir=$(git rev-parse --git-dir 2>/dev/null)
    if [ $? -ne 0 ] || [ -z "$gitdir" ]; then
        return
    fi

    # More code ...
}

After reading a bunch of answers and trying them, I've found various edge cases that mean sometimes they don't fully clean the working copy.

Here's my current bash script for doing it, which works all the time.

#!/bin/sh
git reset --hard
git clean -f -d
git checkout HEAD

Run from working copy root directory.

Write this in each "new activity" after you initialized your new intent->

Intent i = new Intent(this, yourClass.class);
startActivity(i);
finish();

You can use the class org.apache.commons.lang.StringEscapeUtils:

String s = StringEscapeUtils.unescapeHtml("Happy & Sad")

It is working.

<script type="text/javascript">
$(document).ready(function() {
    $('#upload').bind("click",function() 
    { 
        var imgVal = $('#uploadImage').val(); 
        if(imgVal=='') 
        { 
            alert("empty input file"); 

        } 
        return false; 

    }); 
});
</script> 

<input type="file" name="image" id="uploadImage" size="30" /> 
<input type="submit" name="upload" id="upload"  class="send_upload" value="upload" /> 

The most popular way is below:

var obj = {name: "Martin", age: 30, country: "United States"};   _x000D_
// Converting JS object to JSON string_x000D_
var json = JSON.stringify(obj);_x000D_
console.log(json);

I would suggest:

DECLARE @sqlStatement nvarchar(MAX),
        @tableName nvarchar(50) = 'TripEvent',
        @columnName nvarchar(50) = 'CreatedDate';

SELECT                  @sqlStatement = 'ALTER TABLE ' + @tableName + ' DROP CONSTRAINT ' + dc.name + ';'
        FROM            sys.default_constraints AS dc
            LEFT JOIN   sys.columns AS sc
                ON      (dc.parent_column_id = sc.column_id)
        WHERE           dc.parent_object_id = OBJECT_ID(@tableName)
        AND         type_desc = 'DEFAULT_CONSTRAINT'
        AND         sc.name = @columnName
PRINT'   ['+@tableName+']:'+@@SERVERNAME+'.'+DB_NAME()+'@'+CONVERT(VarChar, GETDATE(), 127)+';  '+@sqlStatement;
IF(LEN(@sqlStatement)>0)EXEC sp_executesql @sqlStatement
