you have to add [System.Serializable] to PlayerItem class ,like this:

using System;
[System.Serializable]
public class PlayerItem   {
    public string playerId;
    public string playerLoc;
    public string playerNick;
}

I'm going to post an answer as I don't have enough rep to make a comment, but with wget as posted by Blairg23, you can also provide an out parameter for the path.

 wget.download(url, out=path)

If you are using MS SQL Server 2008 and above you can use table-valued parameters like described here http://www.sommarskog.se/arrays-in-sql-2008.html.

1. Create a table type for each parameter type you will be using

The following command creates a table type for integers:

create type int32_id_list as table (id int not null primary key)

2. Implement helper methods

public static SqlCommand AddParameter<T>(this SqlCommand command, string name, IEnumerable<T> ids)
{
  var parameter = command.CreateParameter();      

  parameter.ParameterName = name;
  parameter.TypeName = typeof(T).Name.ToLowerInvariant() + "_id_list";
  parameter.SqlDbType = SqlDbType.Structured;
  parameter.Direction = ParameterDirection.Input;

  parameter.Value = CreateIdList(ids);

  command.Parameters.Add(parameter);
  return command;
}

private static DataTable CreateIdList<T>(IEnumerable<T> ids)
{
  var table = new DataTable();
  table.Columns.Add("id", typeof (T));

  foreach (var id in ids)
  {
    table.Rows.Add(id);
  }

  return table;
}

3. Use it like this

cmd.CommandText = "select * from TableA where Age in (select id from @age)"; 
cmd.AddParameter("@age", new [] {1,2,3,4,5});

You can use either Windows authentication, if your server is in the domain, or SQL Server authentication. Sa is a system administrator, the root account for SQL Server authentication. But it is a bad practice to use if for connecting to your clients.

You should create your own accounts, and use them to connect to your SQL Server instance. In each connection you set account login, its password and the default database, you want to connect to.

You can access the function itself using arguments.callee ^[MDN]:

if (counter>0) {
    arguments.callee(counter-1);
}

This will break in strict mode, however.

Where, I solved this problem by adding the visibility attribute to the CSS code, it works on my website

Original code:

#zo2-body-wrap .introText .images:before_x000D_
{_x000D_
background:rgba(136,136,136,0.7);_x000D_
width:100%;_x000D_
height:100%;_x000D_
content:"";_x000D_
position:absolute;_x000D_
top:0;_x000D_
opacity:0;_x000D_
transition:all 0.2s ease-in-out 0s;_x000D_
}

Fixed iOS touch code:

#zo2-body-wrap .introText .images:before_x000D_
{_x000D_
background:rgba(136,136,136,0.7);_x000D_
width:100%;_x000D_
height:100%;_x000D_
content:"";_x000D_
position:absolute;_x000D_
top:0;_x000D_
visibility:hidden;_x000D_
opacity:0;_x000D_
transition:all 0.2s ease-in-out 0s;_x000D_
}

string is a shortcut for System.String. The only difference is that you don´t need to reference to System.String namespace. So would be better using string than String.

if you just want to disable submit on enter and submit button too use form's onsubmit event

<form onsubmit="return false;">

You can replace "return false" with call to JS function that will do whatever needed and also submit the form as a last step.

Google provides a start to finish PHP/MySQL solution for an example "Store Locator" application with Google Maps. In this example, they store the lat/lng values as "Float" with a length of "10,6"

http://code.google.com/apis/maps/articles/phpsqlsearch.html

I ran into the same issue. What I needed to do was add a reference at the top of the class and change the CultureInfo of the thread that is currently executing.

using System.Threading;

string cultureName = "fr-CA";
Thread.CurrentThread.CurrentCulture = new CultureInfo(cultureName);

DateTime theDate = new DateTime(2015, 11, 06);
theDate.ToString("g");
Console.WriteLine(theDate);

All you have to do is change the culture name, for example: "en-US" = United States "fr-FR" = French-speaking France "fr-CA" = French-speaking Canada etc...

The easiest way to use PhantomJS in python is via Selenium. The simplest installation method is

1. Install NodeJS
2. Using Node's package manager install phantomjs: npm -g install phantomjs-prebuilt
3. install selenium (in your virtualenv, if you are using that)

After installation, you may use phantom as simple as:

from selenium import webdriver

driver = webdriver.PhantomJS() # or add to your PATH
driver.set_window_size(1024, 768) # optional
driver.get('https://google.com/')
driver.save_screenshot('screen.png') # save a screenshot to disk
sbtn = driver.find_element_by_css_selector('button.gbqfba')
sbtn.click()

If your system path environment variable isn't set correctly, you'll need to specify the exact path as an argument to webdriver.PhantomJS(). Replace this:

driver = webdriver.PhantomJS() # or add to your PATH

... with the following:

driver = webdriver.PhantomJS(executable_path='/usr/local/lib/node_modules/phantomjs/lib/phantom/bin/phantomjs')

• How do I set a proxy for phantomjs/ghostdriver in python webdriver?

The function:

function () {}

returns nothing (or undefined).

Sometimes we want to call a function right as we create it. You might be tempted to try this:

function () {}()

but it results in a SyntaxError.

Using the ! operator before the function causes it to be treated as an expression, so we can call it:

!function () {}()

This will also return the boolean opposite of the return value of the function, in this case true, because !undefined is true. If you want the actual return value to be the result of the call, then try doing it this way:

(function () {})()

You can use this simple code:

One-liner in Kotlin:

window.statusBarColor = ContextCompat.getColor(this, R.color.colorName)

Original answer with Java & manual version check:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    getWindow().setStatusBarColor(getResources().getColor(R.color.colorAccentDark_light, this.getTheme()));
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    getWindow().setStatusBarColor(getResources().getColor(R.color.colorAccentDark_light));
}

Apache 2 mod_headers

You could also enable Apache 2 mod_headers. On Fedora it's already enabled by default. If you use Ubuntu/Debian, enable it like this:

# First enable headers module for Apache 2,
# and then restart the Apache2 service
a2enmod headers
apache2 -k graceful

On Ubuntu/Debian you can configure headers in the file /etc/apache2/conf-enabled/security.conf

#
# Setting this header will prevent MSIE from interpreting files as something
# else than declared by the content type in the HTTP headers.
# Requires mod_headers to be enabled.
#
#Header set X-Content-Type-Options: "nosniff"

#
# Setting this header will prevent other sites from embedding pages from this
# site as frames. This defends against clickjacking attacks.
# Requires mod_headers to be enabled.
#
Header always set X-Frame-Options: "sameorigin"
Header always set X-Content-Type-Options nosniff
Header always set X-XSS-Protection "1; mode=block"
Header always set X-Permitted-Cross-Domain-Policies "master-only"
Header always set Cache-Control "no-cache, no-store, must-revalidate"
Header always set Pragma "no-cache"
Header always set Expires "-1"
Header always set Content-Security-Policy: "default-src 'none';"
Header always set Content-Security-Policy: "script-src 'self' www.google-analytics.com adserver.example.com www.example.com;"
Header always set Content-Security-Policy: "style-src 'self' www.example.com;"

Note: This is the bottom part of the file. Only the last three entries are CSP settings.

The first parameter is the directive, the second is the sources to be white-listed. I've added Google analytics and an adserver, which you might have. Furthermore, I found that if you have aliases, e.g, www.example.com and example.com configured in Apache 2 you should add them to the white-list as well.

Inline code is considered harmful, and you should avoid it. Copy all the JavaScript code and CSS to separate files and add them to the white-list.

While you're at it you could take a look at the other header settings and install mod_security

Your code can be fixed as follows:

import numpy as np, cv
vis = np.zeros((384, 836), np.float32)
h,w = vis.shape
vis2 = cv.CreateMat(h, w, cv.CV_32FC3)
vis0 = cv.fromarray(vis)
cv.CvtColor(vis0, vis2, cv.CV_GRAY2BGR)

Short explanation:

1. np.uint32 data type is not supported by OpenCV (it supports uint8, int8, uint16, int16, int32, float32, float64)
2. cv.CvtColor can't handle numpy arrays so both arguments has to be converted to OpenCV type. cv.fromarray do this conversion.
3. Both arguments of cv.CvtColor must have the same depth. So I've changed source type to 32bit float to match the ddestination.

Also I recommend you use newer version of OpenCV python API because it uses numpy arrays as primary data type:

import numpy as np, cv2
vis = np.zeros((384, 836), np.float32)
vis2 = cv2.cvtColor(vis, cv2.COLOR_GRAY2BGR)

Add this script inside head tag:

<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>

The full paramiko distribution ships with a lot of good demos.

In the demos subdirectory, demo.py and interactive.py have full interactive TTY examples which would probably be overkill for your situation.

In your example above ssh_stdin acts like a standard Python file object, so ssh_stdin.write should work so long as the channel is still open.

I've never needed to write to stdin, but the docs suggest that a channel is closed as soon as a command exits, so using the standard stdin.write method to send a password up probably won't work. There are lower level paramiko commands on the channel itself that give you more control - see how the SSHClient.exec_command method is implemented for all the gory details.

First you have to define attribute in form2(child) you will update this attribute in form2 and also from form1(parent) :

 public string Response { get; set; }

 private void OkButton_Click(object sender, EventArgs e)
 {
    Response = "ok";
 }

 private void CancelButton_Click(object sender, EventArgs e)
 {
    Response = "Cancel";
 }

Calling of form2(child) from form1(parent):

  using (Form2 formObject= new Form2() )
  {
     formObject.ShowDialog();

      string result = formObject.Response; 
      //to update response of form2 after saving in result
      formObject.Response="";

      // do what ever with result...
      MessageBox.Show("Response from form2: "+result); 
  }

     $(document).ready(function () {     
    setTimeout(function () {
                    $(".imgthumbnew").click(function () {
                        $("#divVideo video").attr({
                            "src": $(this).data("item"),
                            "autoplay": "autoplay",        
                        })
                    })
                }, 2000); 
            }
        });

here ".imgthumbnew" is the class of images which are thumbs of videos, an extra attribute is given to them which have video url. u can change according to your convenient.
i would suggest you to give an ID to ur Video tag it would be easy to handle.

I need to run the Postgres database and created an alias for the purpose. The work through is provided below:

$ nano ~/.bash_profile 

# in the bash_profile, insert the following texts:

alias pgst="pg_ctl -D /usr/local/var/postgres start"
alias pgsp="pg_ctl -D /usr/local/var/postgres stop"


$ source ~/.bash_profile 

### This will start the Postgres server 
$ pgst

### This will stop the Postgres server 
$ pgsp

The data series names are defined by the column headers. Add the names to the column headers that you would like to use as titles for each of your data series, select all of the data (including the headers), then re-generate your graph. The names in the headers should then appear as the names in the legend for each series.

The top rated solution is not mathematically correct as same as comments under it -> Math.floor(Math.random() * 6) + 1.

Task: generate random number between 1 and 6.

Math.random() returns floating point number between 0 and 1 (like 0.344717274374 or 0.99341293123 for example), which we will use as a percentage, so Math.floor(Math.random() * 6) + 1 returns some percentage of 6 (max: 5, min: 0) and adds 1. The author got lucky that lower bound was 1., because percentage floor will "maximumly" return 5 which is less than 6 by 1, and that 1 will be added by lower bound 1.

The problems occurs when lower bound is greater than 1. For instance, Task: generate random between 2 and 6.

(following author's logic) Math.floor(Math.random() * 6) + 2, it is obviously seen that if we get 5 here -> Math.random() * 6 and then add 2, the outcome will be 7 which goes beyond the desired boundary of 6.

Another example, Task: generate random between 10 and 12.

(following author's logic) Math.floor(Math.random() * 12) + 10, (sorry for repeating) it is obvious that we are getting 0%-99% percent of number "12", which will go way beyond desired boundary of 12.

So, the correct logic is to take the difference between lower bound and upper bound add 1, and only then floor it (to substract 1, because Math.random() returns 0 - 0.99, so no way to get full upper bound, thats why we adding 1 to upper bound to get maximumly 99% of (upper bound + 1) and then we floor it to get rid of excess). Once we got the floored percentage of (difference + 1), we can add lower boundary to get the desired randomed number between 2 numbers.

The logic formula for that will be: Math.floor(Math.random() * ((up_boundary - low_boundary) + 1)) + 10.

P.s.: Even comments under the top-rated answer were incorrect, since people forgot to add 1 to the difference, meaning that they will never get the up boundary (yes it might be a case if they dont want to get it at all, but the requirenment was to include the upper boundary).

I know this is an older post but it may be useful for those who are looking to show a .NET server side image using jQuery.

You have to use a slightly different logic.

So, $("#<%=myServerimg.ClientID%>").show() will not work if you hid the image using myServerimg.visible = false.

Instead, use the following on server side:

myServerimg.Style.Add("display", "none")

Try This one

<TouchableOpacity onPress={() => this._onPressAppoimentButton()} style={styles.Btn}>
    <Button title="Order Online" style={styles.Btn} > </Button>
</TouchableOpacity>

If you really must use jQuery to solve this problem (NB: you shouldn't):

(function($) {
    $.rand = function(arg) {
        if ($.isArray(arg)) {
            return arg[$.rand(arg.length)];
        } else if (typeof arg === "number") {
            return Math.floor(Math.random() * arg);
        } else {
            return 4;  // chosen by fair dice roll
        }
    };
})(jQuery);

var items = [523, 3452, 334, 31, ..., 5346];
var item = jQuery.rand(items);

This plugin will return a random element if given an array, or a value from [0 .. n) given a number, or given anything else, a guaranteed random value!

For extra fun, the array return is generated by calling the function recursively based on the array's length :)

This modification of a_horse_with_no_name's answer will give you the blocking queries in addition to just the blocked sessions:

SELECT
    activity.pid,
    activity.usename,
    activity.query,
    blocking.pid AS blocking_id,
    blocking.query AS blocking_query
FROM pg_stat_activity AS activity
JOIN pg_stat_activity AS blocking ON blocking.pid = ANY(pg_blocking_pids(activity.pid));

int.TryPasrse() Methode is the best way so if the value was string you will never have an exception , instead of the TryParse Methode return to you bool value so you will know if the parse operation succeeded or failed

string yourText = "2";
int num;
bool res = int.TryParse(yourText, out num);
if (res == true)
{
    // the operation succeeded and you got the number in num parameter
}
else
{
   // the operation failed
}

Program prints ab, goes back one character and prints si overwriting the b resulting asi. Carriage return returns the caret to the first column of the current line. That means the ha will be printed over as and the result is hai

handles lookinng for something > 1 char long. feel free to increase the parm sizes if you like.

For a simple and effective PDF viewer, when you require only limited functionality, you can now (iOS 4.0+) use the QuickLook framework:

First, you need to link against QuickLook.framework and #import <QuickLook/QuickLook.h>;

Afterwards, in either viewDidLoad or any of the lazy initialization methods:

QLPreviewController *previewController = [[QLPreviewController alloc] init];
previewController.dataSource = self;
previewController.delegate = self;
previewController.currentPreviewItemIndex = indexPath.row;
[self presentModalViewController:previewController animated:YES];
[previewController release];

If you're looking for a specific type of control you could use a recursive loop like this one - http://weblogs.asp.net/eporter/archive/2007/02/24/asp-net-findcontrol-recursive-with-generics.aspx

Here's an example I made that returns all controls of the given type

/// <summary>
/// Finds all controls of type T stores them in FoundControls
/// </summary>
/// <typeparam name="T"></typeparam>
private class ControlFinder<T> where T : Control 
{
    private readonly List<T> _foundControls = new List<T>();
    public IEnumerable<T> FoundControls
    {
        get { return _foundControls; }
    }    

    public void FindChildControlsRecursive(Control control)
    {
        foreach (Control childControl in control.Controls)
        {
            if (childControl.GetType() == typeof(T))
            {
                _foundControls.Add((T)childControl);
            }
            else
            {
                FindChildControlsRecursive(childControl);
            }
        }
    }
}

You want to set height which may set for all devices?

Decide upon the design of the site i.e Height on various devices.

Ex:

• Height-100px for bubbles on device with -min-width: 700px.
• Height-50px for bubbles on device with < 700px;

Have your css which has height 50px;

and add this media query

  @media only screen and (min-width: 700px) {
    /* Styles */
    .bubble {
        height: 100px;
        margin: 20px;
    }
    .bubble:after {
        bottom: -50px;
        border-width: 50px 50px 0;
    }
    .bubble:before {
        top: 100px;
        border-width: 52px 52px 0;
    }
    .bubble1 {
        height: 100px;
        margin: 20px;
    }
    .bubble1:after {
        bottom: -50px;
        border-width: 50px 50px 0;
    }
    .bubble1:before {
        top: 100px;
        border-width: 52px 52px 0;
    }
    .bubble2 {
        height: 100px;
        margin: 20px;
    }
    .bubble2:after {
        bottom: -50px;
        border-width: 50px 50px 0;
    }
    .bubble2:before {
        top: 100px;
        border-width: 52px 52px 0;
    }
}

This will make your bubbles have Height of 100px on devices greater than 700px and a margin of 20px;

Ok, I am not sure what are you using(MySQL, SLQ Server, Oracle, MS Access..) But you can try the code below. It work in W3School example DB. Here try this:

SELECT city, max(length(city)) FROM Customers;

In docker image of PHP-FPM, i've see such approach:

# cat /usr/local/etc/php-fpm.d/docker.conf
[global]
error_log = /proc/self/fd/2

[www]
; if we send this to /proc/self/fd/1, it never appears
access.log = /proc/self/fd/2

You can use a post-commit hook.

Put the post-commit hook script in the hooks folder, create a wget_folder in your C:\ drive, and put the wget.exe file in this folder. Add the following code in the file called post-commit.bat

SET REPOS=%1   
SET REV=%2

FOR /f "tokens=*" %%a IN (  
'svnlook uuid %REPOS%'  
) DO (  
SET UUID=%%a  
)  

FOR /f "tokens=*" %%b IN (  
'svnlook changed --revision %REV% %REPOS%'  
) DO (  
SET POST=%%b   
)

echo %REPOS% ----- 1>&2

echo %REV% -- 1>&2

echo %UUID% --1>&2

echo %POST% --1>&2

C:\wget_folder\wget ^   
    --header="Content-Type:text/plain" ^   
    --post-data="%POST%" ^   
    --output-document="-" ^   
    --timeout=2 ^     
    http://localhost:9090/job/Test/build/%UUID%/notifyCommit?rev=%REV%    

where Test = name of the job

echo is used to see the value and you can also add exit 2 at the end to know about the issue and whether the post-commit hook script is running or not.

You can extract method:

public int cmp(String txt, String otherTxt)
{
    if ( txt == null )
        return otjerTxt == null ? 0 : 1;

    if ( otherTxt == null )
          return 1;

    return txt.compareToIgnoreCase(otherTxt);
}

public int compareTo(Metadata other) {
   int result = cmp( name, other.name); 
   if ( result != 0 )  return result;
   return cmp( value, other.value); 

}

You can also use

   $(document).ready(function() {

    //some even that will run ajax request - for example click on a button

    var uname = $('#username').val();
    $.ajax({
    type: 'POST',
    url: 'func.php', //this should be url to your PHP file
    dataType: 'html',
    data: {func: 'toptable', user_id: uname},
    beforeSend: function() {
        $('#right').html('checking');
    },
    complete: function() {},
    success: function(html) {
        $('#right').html(html);
    }
    });

    });
And your func.php:

  function toptable()
 {
  echo 'something happens in here';
 }

Replace @RunWith(MockitoJUnitRunner.class) with @RunWith(MockitoJUnitRunner.Silent.class).

I strongly favour minimal file headers, by which I mean just:

• The hashbang (#! line) if this is an executable script
• Module docstring
• Imports, grouped in the standard way, eg:

  import os    # standard library
  import sys

  import requests  # 3rd party packages

  from mypackage import (  # local source
      mymodule,
      myothermodule,
  )

ie. three groups of imports, with a single blank line between them. Within each group, imports are sorted. The final group, imports from local source, can either be absolute imports as shown, or explicit relative imports.

Everything else is a waste of time, visual space, and is actively misleading.

If you have legal disclaimers or licencing info, it goes into a separate file. It does not need to infect every source code file. Your copyright should be part of this. People should be able to find it in your LICENSE file, not random source code.

Metadata such as authorship and dates is already maintained by your source control. There is no need to add a less-detailed, erroneous, and out-of-date version of the same info in the file itself.

I don't believe there is any other data that everyone needs to put into all their source files. You may have some particular requirement to do so, but such things apply, by definition, only to you. They have no place in “general headers recommended for everyone”.

An authority is a portion of a URI. Your error suggests that it was not expecting one. The authority section is shown below, it is what is known as the website part of the url.

From RFC3986 on URIs:

The following is an example URI and its component parts:

     foo://example.com:8042/over/there?name=ferret#nose
     \_/   \______________/\_________/ \_________/ \__/
      |           |            |            |        |
   scheme     authority       path        query   fragment
      |   _____________________|__
     / \ /                        \
     urn:example:animal:ferret:nose

So there are two formats, one with an authority and one not. Regarding slashes:

"When authority is not present, the path cannot begin with two slash
characters ("//")."

Source: https://tools.ietf.org/rfc/rfc3986.txt (search for text 'authority is not present, the path cannot begin with two slash')

As of April 2018, Chrome (along with several other major browsers) now require the muted attribute too.

Therefore, you should use

<video width="320" height="240" autoplay loop muted>
  <source src="movie.mp4" type="video/mp4" />
</video>

Primitive Data Types :

• Predefined by the language and named by a keyword
• Total no = 8
  boolean
  char
  byte
  short
  integer
  long
  float
  double

Reference/Object Data Types :

• Created using defined constructors of the classes
• Used to access objects
• Default value of any reference variable is null
• Reference variable can be used to refer to any object of the declared type or any compatible type.

try http://code.google.com/p/swinghtmltemplate/

this will allow you to create gui with html-like syntax

I've had exactly the same problem in the past and the only way I found to fix it was to add the callback into the iframe page. Of course that only works when you have control over the iframe content.

This is not a question about make, it is a question about the semantic of the #include directive.

The problem is, that there is no file at the path "../StdCUtil/StdCUtil/split.h". This is the path that results when the compiler combines the include path "../StdCUtil" with the relative path from the #include directive "StdCUtil/split.h".

To fix this, just use -I.. instead of -I../StdCUtil.

If the rest of your system is OK with DateTimeOffset instead of DateTime, there's a really convenient feature:

long unixSeconds = DateTimeOffset.Now.ToUnixTimeSeconds();

Just pass UTC date format from your server side code to client side

and use below syntax -

 {{dateUTCField  +'Z' | date : 'mm/dd/yyyy'}}

 e.g. dateUTCField = '2018-01-09T10:02:32.273' then it display like 01/09/2018

Because of the (occasionally) confusing nature of Java's "pass by reference" behavior I definitely agree with finalizing parameter var's.

Finalizing local var's seems somewhat overkill IMO.

Your onClick request:

<span class="A" onclick="var state = this.className.indexOf('A') > -1; $(this).toggleClass('A', !state).toggleClass('B', state);">Click Me</span>

Try it: https://jsfiddle.net/v15q6b5y/

Just the JS à la jQuery:

$('.selector').toggleClass('A', !state).toggleClass('B', state);

For creating a branch from another one can use this syntax as well:

git push origin refs/heads/<sourceBranch>:refs/heads/<targetBranch>

It is a little shorter than "git checkout -b " + "git push origin "

There is a super() in python also.

Example for how a super class method is called from a sub class method

class Dog(object):
    name = ''
    moves = []

    def __init__(self, name):
        self.name = name

    def moves_setup(self,x):
        self.moves.append('walk')
        self.moves.append('run')
        self.moves.append(x)
    def get_moves(self):
        return self.moves

class Superdog(Dog):

    #Let's try to append new fly ability to our Superdog
    def moves_setup(self):
        #Set default moves by calling method of parent class
        super().moves_setup("hello world")
        self.moves.append('fly')
dog = Superdog('Freddy')
print (dog.name)
dog.moves_setup()
print (dog.get_moves()) 

This example is similar to the one explained above.However there is one difference that super doesn't have any arguments passed to it.This above code is executable in python 3.4 version.

In this case, UIButton is derived from UIControl. This works for object derived from UIControl.

I wanted to reuse "UIBarButtonItem" action on specific use case. Here, UIBarButtonItem doesn't offer method sendActionsForControlEvents:

But luckily, UIBarButtonItem has properties for target & action.

 if(notHappy){        
         SEL exit = self.navigationItem.rightBarButtonItem.action;
         id  world = self.navigationItem.rightBarButtonItem.target;
         [world performSelector:exit];
 }

Here, rightBarButtonItem is of type UIBarButtonItem.

I just created a project which explain what is the difference between all subjects:
https://github.com/piecioshka/rxjs-subject-vs-behavior-vs-replay-vs-async

Here's what I did:

• Extracted the files using WinRAR
• Made my changes to the extracted files
• Opened the original JAR file with WinRAR
• Used the ADD button to replace the files that I modified

That's it. I have tested it with my Nokia and it's working for me.

I wrote following function, it works.

It returns datetime data type. Zero hour, minute, second, miliseconds.

CREATE Function [dbo].[fn_GetLastDate]
(
    @date datetime
)
returns datetime
as
begin

declare @result datetime

 select @result = CHOOSE(month(@date),  
 DATEADD(DAY, 31 -day(@date), @date),
 IIF(YEAR(@date) % 4 = 0, DATEADD(DAY, 29 -day(@date), @date), DATEADD(DAY, 28 -day(@date), @date)), 
 DATEADD(DAY, 31 -day(@date), @date) ,
 DATEADD(DAY, 30 -day(@date), @date), 
 DATEADD(DAY, 31 -day(@date), @date),
 DATEADD(DAY, 30 -day(@date), @date), 
 DATEADD(DAY, 31 -day(@date), @date),
 DATEADD(DAY, 31 -day(@date), @date),
 DATEADD(DAY, 30 -day(@date), @date),
 DATEADD(DAY, 31 -day(@date), @date),
 DATEADD(DAY, 30 -day(@date), @date), 
 DATEADD(DAY, 31 -day(@date), @date))

 return convert(date, @result)

end

It's very easy to use. 2 example:

select [dbo].[fn_GetLastDate]('2016-02-03 12:34:12')

select [dbo].[fn_GetLastDate](GETDATE())

If I have open a package in BIDS ("Business Intelligence Development Studio", the tool you use to design the packages), and do not select any item in it, I have a "Properties" pane in the bottom right containing - among others, the MaximumErrorCount property. If you do not see it, maybe it is minimized and you have to open it (have a look at tabs in the right).

If you cannot find it this way, try the menu: View/Properties Window.

Or try the F4 key.

If you know for sure that there's always going to be exactly one key in the object, then you can use Object.keys:

theTypeIs = Object.keys(myVar)[0];

I think there a better alternative to the answers as of 2019. We can use the global-tunnel-ng package to initialize proxy and not pollute the http or https based code everywhere. So first install global-tunnel-ng package:

npm install global-tunnel-ng

Then change your implementations to initialize proxy if needed as:

const globalTunnel = require('global-tunnel-ng');

globalTunnel.initialize({
  host: 'proxy.host.name.or.ip',
  port: 8080
});

Instead of

InputStream fstream = this.getClass().getResourceAsStream("abc.txt"); 

use

InputStream fstream = this.getClass().getClassLoader().getResourceAsStream("abc.txt");

In this way it will look from the root, not from the path of the current invoking class

You do not need to use moment-timezone for this. The main moment.js library has full functionality for working with UTC and the local time zone.

var testDateUtc = moment.utc("2015-01-30 10:00:00");
var localDate = moment(testDateUtc).local();

From there you can use any of the functions you might expect:

var s = localDate.format("YYYY-MM-DD HH:mm:ss");
var d = localDate.toDate();
// etc...

Note that by passing testDateUtc, which is a moment object, back into the moment() constructor, it creates a clone. Otherwise, when you called .local(), it would also change the testDateUtc value, instead of just the localDate value. Moments are mutable.

Also note that if your original input contains a time zone offset such as +00:00 or Z, then you can just parse it directly with moment. You don't need to use .utc or .local. For example:

var localDate = moment("2015-01-30T10:00:00Z");

Draw a rectangle like sdleihssirhc said!

ctx.fillRect (10, 10, 1, 1);

^-- should draw a 1x1 rectangle at x:10, y:10

I had the same problem. Solved it by using a javascript library called FileSaver

Just call

saveAs(file, 'filename');

Full http post request:

$http.post('apiUrl', myObject, { responseType: 'arraybuffer' })
  .success(function(data) {
            var file = new Blob([data], { type: 'application/pdf' });
            saveAs(file, 'filename.pdf');
        });

Sometimes sorting the whole data ahead is very time consuming. We can groupby first and doing topk for each group:

g = df.groupby(['id']).apply(lambda x: x.nlargest(topk,['value'])).reset_index(drop=True)

The CSS standard enables some advanced formatting. There is a @page directive in CSS that enables some formatting that applies only to paged media (like paper). See http://www.w3.org/TR/1998/REC-CSS2-19980512/page.html.

and for firefox use it

In Firefox, https://bug743252.bugzilla.mozilla.org/attachment.cgi?id=714383 (view page source :: tag HTML).

In your code, replace <html> with <html moznomarginboxes mozdisallowselectionprint>.

Offset Means "the amount or distance by which something is out of line". Margin or Borders are something which makes the actual height or width of an HTML element "out of line". It will help you to remember that :

• offsetHeight is a measurement in pixels of the element's CSS height, including border, padding and the element's horizontal scrollbar.

On the other hand, clientHeight is something which is you can say kind of the opposite of OffsetHeight. It doesn't include the border or margins. It does include the padding because it is something that resides inside of the HTML container, so it doesn't count as extra measurements like margin or border. So :

• clientHeight property returns the viewable height of an element in pixels, including padding, but not the border, scrollbar or margin.

ScrollHeight is all the scrollable area, so your scroll will never run over your margin or border, so that's why scrollHeight doesn't include margin or borders but yeah padding does. So:

• scrollHeight value is equal to the minimum height the element would require in order to fit all the content in the viewport without using a vertical scrollbar. The height is measured in the same way as clientHeight: it includes the element's padding, but not its border, margin or horizontal scrollbar.

Joseph: spinner.setOnItemSelectedListener(this) should be below Spinner firstSpinner = (Spinner) findViewById(R.id.spinner1); on onCreate

I don't know of any direct answer as how to find exactly what process is using the swap space, however, this link may be helpful. Another good one is over here

Also, use a good tool like htop to see which processes are using a lot of memory and how much swap overall is being used.

The correct regular expression formulation of the glob expression d* is ^d, which means match anything that starts with d.

    string input = "Message";
    string pattern = @"^d";
    Regex regex = new Regex(pattern, RegexOptions.IgnoreCase);

(The @ quoting is not necessary in this case, but good practice since many regexes use backslash escapes that need to be left alone, and it also indicates to the reader that this string is special).

You can use Expressions windows: while debugging, menu window -> Show View -> Expressions, then it has place to type variables of which you need to see contents

Judging by the output of the image which you linked in one of your comments:

I tried pasting Endoro's command (Thanks Endoro) directly into the command prompt to add a prefix to files but encountered an error. Solution was to reduce %% to %, so:

The accepted answer using button.tag as information carrier which button has actually been pressed is solid and widely accepted but rather limited since a tag can only hold Ints.

You can make use of Swift's awesome closure-capabilities to have greater flexibility and cleaner code.

I recommend this article: How to properly do buttons in table view cells using Swift closures by Jure Zove.

Applied to your problem:

1. Declare a variable that can hold a closure in your tableview cell like

   var buttonTappedAction : ((UITableViewCell) -> Void)?
   

2. Add an action when the button is pressed that only executes the closure. You did it programmatically with cell.yes.targetForAction("connected", withSender: self) but I would prefer an @IBAction outlet :-)

   @IBAction func buttonTap(sender: AnyObject) {
      tapAction?(self)
   }
   

3. Now pass the content of func connected(sender: UIButton!) { ... } as a closure to cell.tapAction = {<closure content here...>}. Please refer to the article for a more precise explanation and please don't forget to break reference cycles when capturing variables from the environment.

Based on your description of what you want to do, the code seems to be correct as it is. ENDIF isn't a valid SQL loop control keyword. Are you sure that the INSERTS are actually pulling data to put into @Classes? In fact, if it was bad it just wouldn't run.

What you might want to try is to put a few PRINT statements in there. Put a PRINT above each of the INSERTS just outputting some silly text to show that that line is executing. If you get both outputs, then your SELECT...INSERT... is suspect. You could also just do the SELECT in place of the PRINT (that is, without the INSERT) and see exactly what data is being pulled.

This will give you some control over the clicking, and looks tidy

<script>
var timeOut = 0;
function onClick(but)
{
    //code
    clearTimeout(timeOut);
    timeOut = setTimeout(function (){onClick(but)},1000);
}
</script>
<button onclick="onClick(this)">Start clicking</button>

what format?

If you construct a Javascript Date object, you can just subtract them to get a milliseconds difference (edit: or just compare them) :

js>t1 = new Date()
Thu Jan 29 2009 14:19:28 GMT-0500 (Eastern Standard Time)
js>t2 = new Date()
Thu Jan 29 2009 14:19:31 GMT-0500 (Eastern Standard Time)
js>t2-t1
2672
js>t3 = new Date('2009 Jan 1')
Thu Jan 01 2009 00:00:00 GMT-0500 (Eastern Standard Time)
js>t1-t3
2470768442
js>t1>t3
true

Not seen a simple modulus here...

$number         = 1.25;
$wholeAsFloat   = floor($number);   // 1.00
$wholeAsInt     = intval($number);  // 1
$decimal        = $number % 1;      // 0.25

In this case getting both $wholeAs? and $decimal don't depend on the other. (You can just take 1 of the 3 outputs independently.) I've shown $wholeAsFloat and $wholeAsInt because floor() returns a float type number even though the number it returns will always be whole. (This is important if you're passing the result into a type-hinted function parameter.)

I wanted this to split a floating point number of hours/minutes, e.g. 96.25, into hours and minutes separately for a DateInterval instance as 96 hours 15 minutes. I did this as follows:

$interval = new \DateInterval(sprintf("PT%dH%dM", intval($hours), (($hours % 1) * 60)));

I didn't care about seconds in my case.

where returns ActiveRecord::Relation

Now take a look at find_by implementation:

def find_by
  where(*args).take
end

As you can see find_by is the same as where but it returns only one record. This method should be used for getting 1 record and where should be used for getting all records with some conditions.

Here is a base R answer using aggregate and ave :

df1 <- with(mtcars, aggregate(list(n = mpg), list(am = am, gear = gear), length))
df1$prop <- with(df1, n/ave(n, am, FUN = sum))
#Also with prop.table
#df1$prop <- with(df1, ave(n, am, FUN = prop.table))
df1

#  am gear  n      prop
#1  0    3 15 0.7894737
#2  0    4  4 0.2105263
#3  1    4  8 0.6153846
#4  1    5  5 0.3846154 

We can also use prop.table but the output displays differently.

prop.table(table(mtcars$am, mtcars$gear), 1)
   
#            3         4         5
#  0 0.7894737 0.2105263 0.0000000
#  1 0.0000000 0.6153846 0.3846154

ClassLoader.getResourceAsStream and Class.getResourceAsStream are definitely the way to go for loading the resource data. However, I don't believe there's any way of "listing" the contents of an element of the classpath.

In some cases this may be simply impossible - for instance, a ClassLoader could generate data on the fly, based on what resource name it's asked for. If you look at the ClassLoader API (which is basically what the classpath mechanism works through) you'll see there isn't anything to do what you want.

If you know you've actually got a jar file, you could load that with ZipInputStream to find out what's available. It will mean you'll have different code for directories and jar files though.

One alternative, if the files are created separately first, is to include a sort of manifest file containing the list of available resources. Bundle that in the jar file or include it in the file system as a file, and load it before offering the user a choice of resources.

You can use the method Path.GetFileName(yourFileName); (MSDN) to just get the name of the file.

The problem is that there is no class called com.service.SempediaSearchManager on your webapp's classpath. The most likely root causes are:

• the fully qualified classname is incorrect in /WEB-INF/Sempedia-service.xml; i.e. the class name is something else,

• the class is not in your webapp's /WEB-INF/classes directory tree or a JAR file in the /WEB-INF/lib directory.

EDIT : The only other thing that I can think of is that the ClassDefNotFoundException may actually be a result of an earlier class loading / static initialization problem. Check your log files for the first stack trace, and look the nested exceptions, i.e. the "caused by" chain. [If a class load fails one time and you or Spring call Class.forName() again for some reason, then Java won't actually try to load a second time. Instead you will get a ClassDefNotFoundException stack trace that does not explain the real cause of the original failure.]

If you are still stumped, you should take Eclipse out of the picture. Create the WAR file in the form that you are eventually going to deploy it, then from the command line:

1. manually shutdown Tomcat

2. clean out your Tomcat webapp directory,

3. copy the WAR file into the webapp directory,

4. start Tomcat.

If that doesn't solve the problem directly, look at the deployed webapp directory on Tomcat to verify that the "missing" class is in the right place.

From See Java Static Variable Methods:

• It is a variable which belongs to the class and not to object(instance)
• Static variables are initialized only once , at the start of the execution. These variables will be initialized first, before the initialization of any instance variables
• A single copy to be shared by all instances of the class
• A static variable can be accessed directly by the class name and doesn’t need any object.

Instance and class (static) variables are automatically initialized to standard default values if you fail to purposely initialize them. Although local variables are not automatically initialized, you cannot compile a program that fails to either initialize a local variable or assign a value to that local variable before it is used.

What the compiler actually does is to internally produce a single class initialization routine that combines all the static variable initializers and all of the static initializer blocks of code, in the order that they appear in the class declaration. This single initialization procedure is run automatically, one time only, when the class is first loaded.

In case of inner classes, they can not have static fields

An inner class is a nested class that is not explicitly or implicitly declared static.

...

Inner classes may not declare static initializers (§8.7) or member interfaces...

Inner classes may not declare static members, unless they are constant variables...

See JLS 8.1.3 Inner Classes and Enclosing Instances

final fields in Java can be initialized separately from their declaration place this is however can not be applicable to static final fields. See the example below.

final class Demo
{
    private final int x;
    private static final int z;  //must be initialized here.

    static 
    {
        z = 10;  //It can be initialized here.
    }

    public Demo(int x)
    {
        this.x=x;  //This is possible.
        //z=15; compiler-error - can not assign a value to a final variable z
    }
}

This is because there is just one copy of the static variables associated with the type, rather than one associated with each instance of the type as with instance variables and if we try to initialize z of type static final within the constructor, it will attempt to reinitialize the static final type field z because the constructor is run on each instantiation of the class that must not occur to static final fields.

As of Bootstrap 3, you can use Panel classes:

<div class="panel panel-default">Surrounded by border</div>

In Bootstrap 4, you can use Border classes:

<div class="border border-secondary">Surrounded by border</div>

Remove the ' around the point:

mysql_query("UPDATE member_profile SET points=".$points."+1 WHERE user_id = '".$userid."'");

You are "casting" an integer value to string in your original query...

for jQuery we can use below:

by input name:

$('input[name="textboxname"]').val('some value');

by input class:

$('input[type=text].textboxclass').val('some value');

by input id:

$('#textboxid').val('some value');

You can use

org.apache.commons.lang3.StringUtils.containsIgnoreCase(CharSequence str,
                                     CharSequence searchStr);

Checks if CharSequence contains a search CharSequence irrespective of case, handling null. Case-insensitivity is defined as by String.equalsIgnoreCase(String).

A null CharSequence will return false.

This one will be better than regex as regex is always expensive in terms of performance.

For official doc, refer to : StringUtils.containsIgnoreCase

Update :

If you are among the ones who

• don't want to use Apache commons library
• don't want to go with the expensive regex/Pattern based solutions,
• don't want to create additional string object by using toLowerCase,

you can implement your own custom containsIgnoreCase using java.lang.String.regionMatches

public boolean regionMatches(boolean ignoreCase,
                             int toffset,

What is the difference between g++ and gcc?

gcc has evolved from a single language "GNU C Compiler" to be a multi-language "GNU Compiler Collection". The term "GNU C Compiler" is still used sometimes in the context of C programming.

The g++ is the C++ compiler for the GNU Compiler Collection. Like gnat is the Ada compiler for gcc. see Using the GNU Compiler Collection (GCC)

For example, the Ubuntu 16.04 and 18.04 man g++ command returns the GCC(1) manual page.

The Ubuntu 16.04 and 18.04 man gcc states that ...

g++ accepts mostly the same options as gcc

and that the default ...

... use of gcc does not add the C++ library. g++ is a program that calls GCC and automatically specifies linking against the C++ library. It treats .c, .h and .i files as C++ source files instead of C source files unless -x is used. This program is also useful when precompiling a C header file with a .h extension for use in C++ compilations.

Search the gcc man pages for more details on the option variances between gcc and g++.

Which one should be used for general c++ development?

Technically, either gcc or g++ can be used for general C++ development with applicable option settings. However, the g++ default behavior is naturally aligned to a C++ development.

The Ubuntu 18.04 'gcc' man page added, and Ubuntu 20.04 continues to have, the following paragraph:

The usual way to run GCC is to run the executable called gcc, or machine-gcc when cross-compiling, or machine-gcc-version to run a specific version of GCC. When you compile C++ programs, you should invoke GCC as g++ instead.

Unless the variable k is defined, that's probably what's causing your trouble. Something like this will do what you want:

var new_tweets = { };

new_tweets.k = { };

new_tweets.k.tweet_id = 98745521;
new_tweets.k.user_id = 54875;

new_tweets.k.data = { };

new_tweets.k.data.in_reply_to_screen_name = 'other_user';
new_tweets.k.data.text = 'tweet text';

// Will create the JSON string you're looking for.
var json = JSON.stringify(new_tweets);

You can also do it all at once:

var new_tweets = {
  k: {
    tweet_id: 98745521,
    user_id: 54875,
    data: {
      in_reply_to_screen_name: 'other_user',
      text: 'tweet_text'
    }
  }
}

I don't know your test conditions, but a good old switch could work

switch(colour)
{
  case red:
  {
    switch(car)
    { 
      case hyundai: 
      {
        break;
      }
      :
    }
    break;
  }
  :
}

This is for Charts.js 2.0:

The reason some of these are not working is because you should declare your options when you create your chart like so:

$(function () {
    var ctxLine = document.getElementById("myLineChart");
    var myLineChart = new Chart(ctxLine, {
        type: 'line',
        data: dataLine,
        options: {
            scales: {
                yAxes: [{
                    ticks: {
                        min: 0,
                        beginAtZero: true
                    }
                }]
            }
        }

    });
})

Documentation for this is here: http://www.chartjs.org/docs/#scales

The socket has been closed by the client (browser).

A bug in your code:

byte[] outputByte=new byte[4096];
while(in.read(outputByte,0,4096)!=-1){
   output.write(outputByte,0,4096);
}

The last packet read, then write may have a length < 4096, so I suggest:

byte[] outputByte=new byte[4096];
int len;
while(( len = in.read(outputByte, 0, 4096 )) > 0 ) {
   output.write( outputByte, 0, len );
}

It's not your question, but it's my answer... ;-)

You could try using HTML5s sessionStorage it lasts for the duration on the page session. A page session lasts for as long as the browser is open and survives over page reloads and restores. Opening a page in a new tab or window will cause a new session to be initiated.

sessionStorage.setItem("username", "John");

https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Storage#sessionStorage

Browser Compatibility https://code.google.com/p/sessionstorage/ compatible with every A-grade browser, included iPhone or Android. http://www.nczonline.net/blog/2009/07/21/introduction-to-sessionstorage/

Make sure "html_files" is a directory in your app's main bundle, and not just a group in Xcode.

setBackground(getContext().getResources().getDrawable(R.drawable.green_rounded_frame));

Well, if you're returning Dogs, you'd do:

public IQueryable<Dog> GetDogsWithBreedNames()
{
    var db = new DogDataContext(ConnectString);
    return from d in db.Dogs
           join b in db.Breeds on d.BreedId equals b.BreedId
           select d;
}

If you want the Breed eager-loaded and not lazy-loaded, just use the appropriate DataLoadOptions construct.

I just found this extension called beautify in the Market Place and yes, it's another config\settings file. :)

Beautify javascript, JSON, CSS, Sass, and HTML in Visual Studio Code.

VS Code uses js-beautify internally, but it lacks the ability to modify the style you wish to use. This extension enables running js-beautify in VS Code, AND honouring any .jsbeautifyrc file in the open file's path tree to load your code styling. Run with F1 Beautify (to beautify a selection) or F1 Beautify file.

For help on the settings in the .jsbeautifyrc see Settings.md

Here is the GitHub repository: https://github.com/HookyQR/VSCodeBeautify

You can use cmd + ; for Mac or Ctrl + Alt + Shift + S for Windows/Linux to pull up the Project Structure dialog. In there, you can set the JDK location as well as the Android SDK location.

To get your JDK location, run /usr/libexec/java_home -v 1.7 in terminal. Send 1.7 for Java 7 or 1.8 for Java 8.

I have faced similar problem and it was returning #N/A. That means matching data is present but you might having extra space in the M3 column record, that may prevent it from getting exact value. Because you have set last parameter as FALSE, it is looking for "exact match". This formula is correct: =VLOOKUP(M3,Sheet1!$A$2:$Q$47,13,FALSE)

Well, your code worked for me (running Chrome 5.0.307.9 and Firefox 3.5.8 on Ubuntu 9.10), though I switched

overflow-y: scroll;

to

overflow-y: auto;

Don't go inside mysql, just open Command prompt and directly type this:

mysqldump -u [uname] -p[pass] db_name > db_backup.sql

Are you trying to pass the command line arguments to the program AS you launch it? I am working on something right now that does exactly this, and it was a lot simpler than I thought. If I go into the command line, and type

C:\folder\app.exe/xC:\folder\file.txt

then my application launches, and creates a file in the specified directory with the specified name.

I wanted to do this through a Powershell script on a remote machine, and figured out that all I needed to do was put

$s = New-PSSession -computername NAME -credential LOGIN
    Invoke-Command -session $s -scriptblock {C:\folder\app.exe /xC:\folder\file.txt}
Remove-PSSession $s

(I have a bunch more similar commands inside the session, this is just the minimum it requires to run) notice the space between the executable, and the command line arguments. It works for me, but I am not sure exactly how your application works, or if that is even how you pass arguments to it.

*I can also have my application push the file back to my own local computer by changing the script-block to

C:\folder\app.exe /x"\\LocalPC\DATA (C)\localfolder\localfile.txt"

You need the quotes if your file-path has a space in it.

EDIT: actually, this brought up some silly problems with Powershell launching the application as a service or something, so I did some searching, and figured out that you can call CMD to execute commands for you on the remote computer. This way, the command is carried out EXACTLY as if you had just typed it into a CMD window on the remote machine. Put the command in the scriptblock into double quotes, and then put a cmd.exe /C before it. like this:

cmd.exe /C "C:\folder\app.exe/xC:\folder\file.txt"

this solved all of the problems that I have been having recently.

EDIT EDIT: Had more problems, and found a much better way to do it.

start-process -filepath C:\folder\app.exe -argumentlist "/xC:\folder\file.txt"

and this doesn't hang up your terminal window waiting for the remote process to end. Just make sure you have a way to terminate the process if it doesn't do that on it's own. (mine doesn't, required the coding of another argument)

when reimporting your keys from the old keyring, you need to specify the command:

gpg --allow-secret-key-import --import <keyring>

otherwise it will only import the public keys, not the private keys.

It is also possible to open the pdf link in a new window and let the browser handle the rest:

window.open(pdfUrl, '_blank');

or:

window.open(pdfUrl);

As stated by pnt you can have multiple versions of both 32bit and 64bit Java installed at the same time on the same machine.

Taking it further from there: Here's how it might be possible to set any runtime parameters for each of those installations:

You can run javacpl.exe or javacpl.cpl of the respective Java-version itself (bin-folder). The specific control panel opens fine. Adding parameters there is possible.

You can use CAST and CONVERT to switch between different types of encodings. See: http://dev.mysql.com/doc/refman/5.0/en/charset-convert.html

SELECT column1, CONVERT(column2 USING utf8)
FROM my_table 
WHERE my_condition;

There is a problem with your solution code--it will only escape the first occurrence of each special character. For example:

escapeHtml('Kip\'s <b>evil</b> "test" code\'s here');
Actual:   Kip&#039;s &lt;b&gt;evil</b> &quot;test" code's here
Expected: Kip&#039;s &lt;b&gt;evil&lt;/b&gt; &quot;test&quot; code&#039;s here

Here is code that works properly:

function escapeHtml(text) {
  return text
      .replace(/&/g, "&")
      .replace(/</g, "&lt;")
      .replace(/>/g, "&gt;")
      .replace(/"/g, "&quot;")
      .replace(/'/g, "&#039;");
}

Update

The following code will produce identical results to the above, but it performs better, particularly on large blocks of text (thanks jbo5112).

function escapeHtml(text) {
  var map = {
    '&': '&',
    '<': '&lt;',
    '>': '&gt;',
    '"': '&quot;',
    "'": '&#039;'
  };
  
  return text.replace(/[&<>"']/g, function(m) { return map[m]; });
}

You should wrap your elements inside a container, then use new CSS3 features like css grid, free course, and then use grid-gap:value that was created for your specific problem

span{_x000D_
  border:1px solid red;_x000D_
}_x000D_
.inRow{_x000D_
  display:grid;_x000D_
  grid-template-columns:repeat(auto-fill,auto);_x000D_
  grid-gap:10px /*This add space between elements, only works on grid items*/_x000D_
}_x000D_
.inColumn{_x000D_
  display:grid;_x000D_
  grid-template-rows:repeat(auto-fill,auto);_x000D_
  grid-gap:15px;_x000D_
}

<div class="inrow">_x000D_

  <span>4</span>_x000D_
  <span>5</span>_x000D_
  <span>6</span>_x000D_
</div>

What about this approach:

 <head>_x000D_
 <style type="text/css">_x000D_
  div.gradient {_x000D_
   color: #000000;_x000D_

I did exactly what you're looking for in a very simple way. It is perfectly smooth in Google Chrome and Opera, and almost perfect in Firefox and Safari. Not tested in IE.

function newTab(url)
{
    var tab=window.open("");
    tab.document.write("<!DOCTYPE html><html>"+document.getElementsByTagName("html")[0].innerHTML+"</html>");
    tab.document.close();
    window.location.href=url;
}

Fiddle : http://jsfiddle.net/tFCnA/show/

Explanations:
Let's say there is windows A1 and B1 and websites A2 and B2.
Instead of opening B2 in B1 and then return to A1, I open B2 in A1 and re-open A2 in B1.
(Another thing that makes it work is that I don't make the user re-download A2, see line 4)

^{The only thing you may doesn't like is that the new tab opens before the main page.}

The normal idea would be to run the command and then use $? to get the exit code. However, some times you have multiple cases in which you need to get the exit code. For example, you might need to hide it's output but still return the exit code, or print both the exit code and the output.

ec() { [[ "$1" == "-h" ]] && { shift && eval $* > /dev/null 2>&1; ec=$?; echo $ec; } || eval $*; ec=$?; }

This will give you the option to suppress the output of the command you want the exit code for. When the output is suppressed for the command, the exit code will directly be returned by the function.

I personally like to put this function in my .bashrc file

Below I demonstrate a few ways in which you can use this:

# In this example, the output for the command will be
# normally displayed, and the exit code will be stored
# in the variable $ec.

$ ec echo test
test
$ echo $ec
0

# In this example, the exit code is output
# and the output of the command passed
# to the `ec` function is suppressed.

$ echo "Exit Code: $(ec -h echo test)"
Exit Code: 0

# In this example, the output of the command
# passed to the `ec` function is suppressed
# and the exit code is stored in `$ec`

$ ec -h echo test
$ echo $ec
0

Solution to your code using this function

#!/bin/bash
if [[ "$(ec -h 'ls -l | grep p')" != "0" ]]; then
    echo "Error when executing command: 'grep p' [$ec]"
    exit $ec;
fi

You should also note that the exit code you will be seeing will be for the grep command that's being run, as it is the last command being executed. Not the ls.

I'm using OS X (Yosemite) and this error happened to me when I upgraded from Mavericks to Yosemite. It was solved by using this command

sudo /usr/local/mysql/support-files/mysql.server start

I had this problem too, somehow my code did not present the exact values but rounded the number in seconds to 0.0 (if milliseconds was under 1 second). What helped me out is adding the decimal to the division value.

double time_seconds = time_milliseconds / 1000.0;   // add the decimal
System.out.println(time_milliseconds);              // Now this should give you the right value.

I don't know which version of MySQL you're using, but here are possible locations of the my.cnf file for version 5.5 (taken from here) on Mac OS X:

1. /etc/my.cnf
2. /etc/mysql/my.cnf
3. SYSCONFDIR/my.cnf
4. $MYSQL_HOME/my.cnf
5. defaults-extra-file (the file specified with --defaults-extra-file=path, if any)
6. ~/.my.cnf

It can be done with a while loop (foreach doesn't support this):

my @arr = (1111, 2222, 3333);

while (my ($index, $element) = each(@arr))
{
   # You may need to "use feature 'say';"
   say "Index: $index, Element: $element";
}

Output:

Index: 0, Element: 1111
Index: 1, Element: 2222
Index: 2, Element: 3333

Perl version: 5.14.4

In C++, unlike (say) Java, an instance of a nested class doesn't intrinsically belong to any instance of the enclosing class. So bar::getA doesn't have any specific instance of foo whose a it can be returning. I'm guessing that what you want is something like:

    class bar {
      private:
        foo * const owner;
      public:
        bar(foo & owner) : owner(&owner) { }
        int getA() {return owner->a;}
    };

But even for this you may have to make some changes, because in versions of C++ before C++11, unlike (again, say) Java, a nested class has no special access to its enclosing class, so it can't see the protected member a. This will depend on your compiler version. (Hat-tip to Ken Wayne VanderLinde for pointing out that C++11 has changed this.)

Just wondering why you are using 2 directives?

It seems like, in this case it would be more straightforward to have a controller as the parent - handle adding the data from your service to its $scope, and pass the model you need from there into your warrantyDirective.

Or for that matter, you could use 0 directives to achieve the same result. (ie. move all functionality out of the separate directives and into a single controller).

It doesn't look like you're doing any explicit DOM transformation here, so in this case, perhaps using 2 directives is overcomplicating things.

Alternatively, have a look at the Angular documentation for directives: http://docs.angularjs.org/guide/directive The very last example at the bottom of the page explains how to wire up dependent directives.

If s is your string:

s.replace(/^[^(]*\(/, "") // trim everything before first parenthesis
 .replace(/\)[^(]*$/, "") // trim everything after last parenthesis
 .split(/\)[^(]*\(/);      // split between parenthesis

The API has been updated. Not sure when it changed but according to Damien Edwards in late December, you can now do this:

var remoteIpAddress = request.HttpContext.Connection.RemoteIpAddress;

My solution to this was a left over mysql.sock in the /var/lib/mysql/ directory from a hard shutdown. Mysql thought it was already running when it was not running.

I couldn't get any of these to work currently, because for me it is (1) not required and (2) need the option to return to default selectable. So here's a heavy handed option if you are using jQuery:

var $selects = $('select');_x000D_
$selects.change(function () {_x000D_
  var option = $('option:default', this);_x000D_
  if(option && option.is(':selected')) {_x000D_
    $(this).css('color', '#999');_x000D_
  }_x000D_
  else {_x000D_
    $(this).css('color', '#555');_x000D_
  }_x000D_
});_x000D_
_x000D_
$selects.each(function() {_x000D_
  $(this).change();_x000D_
});

option {_x000D_
    color: #555;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<select name="in-op">_x000D_
    <option default selected>Select Option</option>_x000D_
    <option>Option 1</option>_x000D_
    <option>Option 2</option>_x000D_
    <option>Option 3</option>_x000D_
</select>

I've had this problem before, and the solution is simply to call window.print() in IE, as opposed to calling print from the window instance:

function printPage(htmlPage)
    {
        var w = window.open("about:blank");
        w.document.write(htmlPage);
        if (navigator.appName == 'Microsoft Internet Explorer') window.print();
        else w.print();
    }

To complement the previous stated solution, use:

str = str.replace("%", "%%");

Many ways to do this. ismember is the first that comes to mind, since it is a set membership action you wish to take. Thus

X = primes(20);
ismember([15 17],X)
ans =
      0    1

Since 15 is not prime, but 17 is, ismember has done its job well here.

Of course, find (or any) will also work. But these are not vectorized in the sense that ismember was. We can test to see if 15 is in the set represented by X, but to test both of those numbers will take a loop, or successive tests.

~isempty(find(X == 15))
~isempty(find(X == 17))

or,

any(X == 15)
any(X == 17)

Finally, I would point out that tests for exact values are dangerous if the numbers may be true floats. Tests against integer values as I have shown are easy. But tests against floating point numbers should usually employ a tolerance.

tol = 10*eps;
any(abs(X - 3.1415926535897932384) <= tol)

A very simple solution:

df <- read.csv("df.csv",sep=",",head=T)
x <- cbind(df$Xax,df$Xax,df$Xax,df$Xax)
y <- cbind(df$A,df$B,df$C,df$D)
matplot(x,y,type="p")

please note it just plots the data and it does not plot any regression line.

This is a refresh button method, but it works well in my application. in finish() you kill the instances

public void refresh(View view){          //refresh is onClick name given to the button
    onRestart();
}

@Override
protected void onRestart() {

    // TODO Auto-generated method stub
    super.onRestart();
    Intent i = new Intent(lala.this, lala.class);  //your class
    startActivity(i);
    finish();

}

This is specific for each site. So if you type that once, you will only get through that site and all other sites will need a similar type-through.

It is also remembered for that site and you have to click on the padlock to reset it (so you can type it again):

Needless to say use of this "feature" is a bad idea and is unsafe - hence the name.

You should find out why the site is showing the error and/or stop using it until they fix it. HSTS specifically adds protections for bad certs to prevent you clicking through them. The fact it's needed suggests there is something wrong with the https connection - like the site or your connection to it has been hacked.

The chrome developers also do change this periodically. They changed it recently from badidea to thisisunsafe so everyone using badidea, suddenly stopped being able to use it. You should not depend on it. As Steffen pointed out in the comments below, it is available in the code should it change again though they now base64 encode it to make it more obscure. The last time they changed they put this comment in the commit:

Rotate the interstitial bypass keyword

The security interstitial bypass keyword hasn't changed in two years and awareness of the bypass has been increased in blogs and social media. Rotate the keyword to help prevent misuse.

I think the message from the Chrome team is clear - you should not use it. It would not surprise me if they removed it completely in future.

If you are using this when using a self-signed certificate for local testing then why not just add your self-signed certificate certificate to your computer's certificate store so you get a green padlock and do not have to type this? Note Chrome insists on a SAN field in certificates now so if just using the old subject field then even adding it to the certificate store will not result in a green padlock.

If you leave the certificate untrusted then certain things do not work. Caching for example is completely ignored for untrusted certificates. As is HTTP/2 Push.

HTTPS is here to stay and we need to get used to using it properly - and not bypassing the warnings with a hack that is liable to change and doesn't work the same as a full HTTPS solution.

While dict.copy() and dict(dict1) generates a copy, they are only shallow copies. If you want a deep copy, copy.deepcopy(dict1) is required. An example:

>>> source = {'a': 1, 'b': {'m': 4, 'n': 5, 'o': 6}, 'c': 3}
>>> copy1 = x.copy()
>>> copy2 = dict(x)
>>> import copy
>>> copy3 = copy.deepcopy(x)
>>> source['a'] = 10  # a change to first-level properties won't affect copies
>>> source
{'a': 10, 'c': 3, 'b': {'m': 4, 'o': 6, 'n': 5}}
>>> copy1
{'a': 1, 'c': 3, 'b': {'m': 4, 'o': 6, 'n': 5}}
>>> copy2
{'a': 1, 'c': 3, 'b': {'m': 4, 'o': 6, 'n': 5}}
>>> copy3
{'a': 1, 'c': 3, 'b': {'m': 4, 'o': 6, 'n': 5}}
>>> source['b']['m'] = 40  # a change to deep properties WILL affect shallow copies 'b.m' property
>>> source
{'a': 10, 'c': 3, 'b': {'m': 40, 'o': 6, 'n': 5}}
>>> copy1
{'a': 1, 'c': 3, 'b': {'m': 40, 'o': 6, 'n': 5}}
>>> copy2
{'a': 1, 'c': 3, 'b': {'m': 40, 'o': 6, 'n': 5}}
>>> copy3  # Deep copy's 'b.m' property is unaffected
{'a': 1, 'c': 3, 'b': {'m': 4, 'o': 6, 'n': 5}}

Regarding shallow vs deep copies, from the Python copy module docs:

The difference between shallow and deep copying is only relevant for compound objects (objects that contain other objects, like lists or class instances):

• A shallow copy constructs a new compound object and then (to the extent possible) inserts references into it to the objects found in the original.
• A deep copy constructs a new compound object and then, recursively, inserts copies into it of the objects found in the original.

I added the control to the Triggers tag in the update panel:

    </ContentTemplate>
    <Triggers>
        <asp:PostBackTrigger ControlID="exportLinkButton" />
    </Triggers>
</asp:UpdatePanel>

This way the exportLinkButton will trigger the UpdatePanel to update.

For muting library("name_of_library") codes, meanly just showing the codes, {r loadlib, echo=T, results='hide', message=F, warning=F} is great. And imho a better way than library(package, warn.conflicts=F, quietly=T)

Yes, I think for Windows users you need to change all the python3 calls to python to solve your original error. This change will run the Python version set in your current environment. If you need to keep this call as it is (aka python3) because you are working in cross-platform or for any other reason, then a work around is to create a soft link. To create it, go to the folder that contains the Python executable and create the link. For example, this worked in my case in Windows 10 using mklink:

cd C:\Python3
mklink python3.exe python.exe

Use a (soft) symbolic link in Linux:

cd /usr/bin/python3
ln -s python.exe python3.exe

Following worked for me

curl -O -L  https://sourceforge.net/projects/sshpass/files/sshpass/1.06/sshpass-1.06.tar.gz && tar xvzf sshpass-1.06.tar.gz
cd sshpass-1.06/
./configure
sudo make install

<< is the left-shift operator, as it is in many other languages.

Here RAM_DEPTH will be 1 left-shifted by 8 bits, which is equivalent to 2^8, or 256.

Python really tries hard to intelligently set sys.path. How it is set can get really complicated. The following guide is a watered-down, somewhat-incomplete, somewhat-wrong, but hopefully-useful guide for the rank-and-file python programmer of what happens when python figures out what to use as the initial values of sys.path, sys.executable, sys.exec_prefix, and sys.prefix on a normal python installation.

First, python does its level best to figure out its actual physical location on the filesystem based on what the operating system tells it. If the OS just says "python" is running, it finds itself in $PATH. It resolves any symbolic links. Once it has done this, the path of the executable that it finds is used as the value for sys.executable, no ifs, ands, or buts.

Next, it determines the initial values for sys.exec_prefix and sys.prefix.

If there is a file called pyvenv.cfg in the same directory as sys.executable or one directory up, python looks at it. Different OSes do different things with this file.

One of the values in this config file that python looks for is the configuration option home = <DIRECTORY>. Python will use this directory instead of the directory containing sys.executable when it dynamically sets the initial value of sys.prefix later. If the applocal = true setting appears in the pyvenv.cfg file on Windows, but not the home = <DIRECTORY> setting, then sys.prefix will be set to the directory containing sys.executable.

Next, the PYTHONHOME environment variable is examined. On Linux and Mac, sys.prefix and sys.exec_prefix are set to the PYTHONHOME environment variable, if it exists, superseding any home = <DIRECTORY> setting in pyvenv.cfg. On Windows, sys.prefix and sys.exec_prefix is set to the PYTHONHOME environment variable, if it exists, unless a home = <DIRECTORY> setting is present in pyvenv.cfg, which is used instead.

Otherwise, these sys.prefix and sys.exec_prefix are found by walking backwards from the location of sys.executable, or the home directory given by pyvenv.cfg if any.

If the file lib/python<version>/dyn-load is found in that directory or any of its parent directories, that directory is set to be to be sys.exec_prefix on Linux or Mac. If the file lib/python<version>/os.py is is found in the directory or any of its subdirectories, that directory is set to be sys.prefix on Linux, Mac, and Windows, with sys.exec_prefix set to the same value as sys.prefix on Windows. This entire step is skipped on Windows if applocal = true is set. Either the directory of sys.executable is used or, if home is set in pyvenv.cfg, that is used instead for the initial value of sys.prefix.

If it can't find these "landmark" files or sys.prefix hasn't been found yet, then python sets sys.prefix to a "fallback" value. Linux and Mac, for example, use pre-compiled defaults as the values of sys.prefix and sys.exec_prefix. Windows waits until sys.path is fully figured out to set a fallback value for sys.prefix.

Then, (what you've all been waiting for,) python determines the initial values that are to be contained in sys.path.

1. The directory of the script which python is executing is added to sys.path. On Windows, this is always the empty string, which tells python to use the full path where the script is located instead.
2. The contents of PYTHONPATH environment variable, if set, is added to sys.path, unless you're on Windows and applocal is set to true in pyvenv.cfg.
3. The zip file path, which is <prefix>/lib/python35.zip on Linux/Mac and os.path.join(os.dirname(sys.executable), "python.zip") on Windows, is added to sys.path.
4. If on Windows and no applocal = true was set in pyvenv.cfg, then the contents of the subkeys of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ are added, if any.
5. If on Windows and no applocal = true was set in pyvenv.cfg, and sys.prefix could not be found, then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ is added, if it exists;
6. If on Windows and no applocal = true was set in pyvenv.cfg, then the contents of the subkeys of the registry key HK_LOCAL_MACHINE\Software\Python\PythonCore\<DLLVersion>\PythonPath\ are added, if any.
7. If on Windows and no applocal = true was set in pyvenv.cfg, and sys.prefix could not be found, then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ is added, if it exists;
8. If on Windows, and PYTHONPATH was not set, the prefix was not found, and no registry keys were present, then the relative compile-time value of PYTHONPATH is added; otherwise, this step is ignored.
9. Paths in the compile-time macro PYTHONPATH are added relative to the dynamically-found sys.prefix.
10. On Mac and Linux, the value of sys.exec_prefix is added. On Windows, the directory which was used (or would have been used) to search dynamically for sys.prefix is added.

At this stage on Windows, if no prefix was found, then python will try to determine it by searching all the directories in sys.path for the landmark files, as it tried to do with the directory of sys.executable previously, until it finds something. If it doesn't, sys.prefix is left blank.

Finally, after all this, Python loads the site module, which adds stuff yet further to sys.path:

It starts by constructing up to four directories from a head and a tail part. For the head part, it uses sys.prefix and sys.exec_prefix; empty heads are skipped. For the tail part, it uses the empty string and then lib/site-packages (on Windows) or lib/pythonX.Y/site-packages and then lib/site-python (on Unix and Macintosh). For each of the distinct head-tail combinations, it sees if it refers to an existing directory, and if so, adds it to sys.path and also inspects the newly added path for configuration files.

I faced the same issue. fixed by using reload.

import the_module_name
from importlib import reload
reload(the_module_name)

No, you can't undo, rollback or reverse a commit.

STOP THE DATABASE!

(Note: if you deleted the data directory off the filesystem, do NOT stop the database. The following advice applies to an accidental commit of a DELETE or similar, not an rm -rf /data/directory scenario).

If this data was important, STOP YOUR DATABASE NOW and do not restart it. Use pg_ctl stop -m immediate so that no checkpoint is run on shutdown.

You cannot roll back a transaction once it has commited. You will need to restore the data from backups, or use point-in-time recovery, which must have been set up before the accident happened.

If you didn't have any PITR / WAL archiving set up and don't have backups, you're in real trouble.

Urgent mitigation

Once your database is stopped, you should make a file system level copy of the whole data directory - the folder that contains base, pg_clog, etc. Copy all of it to a new location. Do not do anything to the copy in the new location, it is your only hope of recovering your data if you do not have backups. Make another copy on some removable storage if you can, and then unplug that storage from the computer. Remember, you need absolutely every part of the data directory, including pg_xlog etc. No part is unimportant.

Exactly how to make the copy depends on which operating system you're running. Where the data dir is depends on which OS you're running and how you installed PostgreSQL.

Ways some data could've survived

If you stop your DB quickly enough you might have a hope of recovering some data from the tables. That's because PostgreSQL uses multi-version concurrency control (MVCC) to manage concurrent access to its storage. Sometimes it will write new versions of the rows you update to the table, leaving the old ones in place but marked as "deleted". After a while autovaccum comes along and marks the rows as free space, so they can be overwritten by a later INSERT or UPDATE. Thus, the old versions of the UPDATEd rows might still be lying around, present but inaccessible.

Additionally, Pg writes in two phases. First data is written to the write-ahead log (WAL). Only once it's been written to the WAL and hit disk, it's then copied to the "heap" (the main tables), possibly overwriting old data that was there. The WAL content is copied to the main heap by the bgwriter and by periodic checkpoints. By default checkpoints happen every 5 minutes. If you manage to stop the database before a checkpoint has happened and stopped it by hard-killing it, pulling the plug on the machine, or using pg_ctl in immediate mode you might've captured the data from before the checkpoint happened, so your old data is more likely to still be in the heap.

Now that you have made a complete file-system-level copy of the data dir you can start your database back up if you really need to; the data will still be gone, but you've done what you can to give yourself some hope of maybe recovering it. Given the choice I'd probably keep the DB shut down just to be safe.

Recovery

You may now need to hire an expert in PostgreSQL's innards to assist you in a data recovery attempt. Be prepared to pay a professional for their time, possibly quite a bit of time.

I posted about this on the Pg mailing list, and ?????? ?????? linked to depesz's post on pg_dirtyread, which looks like just what you want, though it doesn't recover TOASTed data so it's of limited utility. Give it a try, if you're lucky it might work.

See: pg_dirtyread on GitHub.

I've removed what I'd written in this section as it's obsoleted by that tool.

See also PostgreSQL row storage fundamentals

Prevention

See my blog entry Preventing PostgreSQL database corruption.

On a semi-related side-note, if you were using two phase commit you could ROLLBACK PREPARED for a transction that was prepared for commit but not fully commited. That's about the closest you get to rolling back an already-committed transaction, and does not apply to your situation.

This solution is better because of no need to define the source model. But the name of the serializer field should be the same as the foreign key field name

class ItemSerializer(serializers.ModelSerializer):
    category = serializers.SlugRelatedField(read_only=True, slug_field='title')

    class Meta:
        model = Item
        fields = ('id', 'name', 'category')

You need to take out the $ signs before the row numbers in the formula....and the row number used in the formula should correspond to the first row of data, so if you are applying this to the ("applies to") range $B$2:$B$5 it must be this formula

=$B2>$C2

by using that "relative" version rather than your "absolute" one Excel (implicitly) adjusts the formula for each row in the range, as if you were copying the formula down

You need to add a name to your <select> element:

<select id="testSelect" name="testSelect">

It will be posted to the server, and you can see it using:

Request.Form["testSelect"]

you need to set the margin of the body to 0 for the table to stretch the full width. alternatively you can set the margin of the table to a negative number as well.

@xpmatteo has the answer to disabling portions of code, but in addition to this, the default eclipse settings should be set to only format edited lines of code instead of the whole file.

Preferences->Java->Editor->Save Actions->Format Source Code->Format Edited Lines

This would have prevented it from happening in the first place since your coworkers are reformatting code they didn't actually change. This is a good practice to prevent mishaps that render diff on your source control useless (when an entire file is reformatted because of minor format setting differences).

It would also prevent the reformatting if the on/off tags option was turned off.

At the very least, if this were true a compiler could trivially optimise a <= b to !(a > b), and so even if the comparison itself were actually slower, with all but the most naive compiler you would not notice a difference.

Always remember to be careful with nulls in pl/sql conditional clauses as null is never greater, smaller, equal or unequal to anything. Best way to avoid them is to use nvl.

For example

declare
  i integer;
begin
  if i <> 1 then
    i:=1;
    foobar();
  end if;
end;
/

Never goes inside the if clause.

These would work.

if 1<>nvl(i,1) then
if i<> 1 or i is null then

If you use df.replace([None], np.nan, inplace=True), this changed all datetime objects with missing data to object dtypes. So now you may have broken queries unless you change them back to datetime which can be taxing depending on the size of your data.

If you want to use this method, you can first identify the object dtype fields in your df and then replace the None:

obj_columns = list(df.select_dtypes(include=['object']).columns.values)
df[obj_columns] = df[obj_columns].replace([None], np.nan)

You do not want to do this in general. Reseed can create data integrity problems. It is really only for use on development systems where you are wiping out all test data and starting over. It should not be used on a production system in case all related records have not been deleted (not every table that should be in a foreign key relationship is!). You can create a mess doing this and especially if you mean to do it on a regular basis after every delete. It is a bad idea to worry about gaps in you identity field values.

Try this:

if string[0] in range(10):

As David pointed out, I would go with KB in most cases.

php_value post_max_size 2K

Note: my form is simple, just a few text boxes, not long text.

(PHP shorthand for KB is K, as outlined here.)

The @ symbol serves 2 purposes in C#:

Firstly, it allows you to use a reserved keyword as a variable like this:

int @int = 15;

The second option lets you specify a string without having to escape any characters. For instance the '\' character is an escape character so typically you would need to do this:

var myString = "c:\\myfolder\\myfile.txt"

alternatively you can do this:

var myString = @"c:\myFolder\myfile.txt"

Walkthrough: Using Multiple Programming Languages in a Web Site Project http://msdn.microsoft.com/en-us/library/ms366714.aspx

By default, the App_Code folder does not allow multiple programming languages. However, in a Web site project you can modify your folder structure and configuration settings to support multiple programming languages such as Visual Basic and C#. This allows ASP.NET to create multiple assemblies, one for each language. For more information, see Shared Code Folders in ASP.NET Web Projects. Developers commonly include multiple programming languages in Web applications to support multiple development teams that operate independently and prefer different programming languages.

You want sys.exit(). From Python's docs:

>>> import sys
>>> print sys.exit.__doc__
exit([status])

Exit the interpreter by raising SystemExit(status).
If the status is omitted or None, it defaults to zero (i.e., success).
If the status is numeric, it will be used as the system exit status.
If it is another kind of object, it will be printed and the system
exit status will be one (i.e., failure).

So, basically, you'll do something like this:

from sys import exit

# Code!

exit(0) # Successful exit

According to this link

Actually, SO_REUSEADDR flag can lead to much greater consequences: SO_REUSADDR permits you to use a port that is stuck in TIME_WAIT, but you still can not use that port to establish a connection to the last place it connected to. What? Suppose I pick local port 1010, and connect to foobar.com port 300, and then close locally, leaving that port in TIME_WAIT. I can reuse local port 1010 right away to connect to anywhere except for foobar.com port 300.

However you can completely avoid TIME_WAIT state by ensuring that the remote end initiates the closure (close event). So the server can avoid problems by letting the client close first. The application protocol must be designed so that the client knows when to close. The server can safely close in response to an EOF from the client, however it will also need to set a timeout when it is expecting an EOF in case the client has left the network ungracefully. In many cases simply waiting a few seconds before the server closes will be adequate.

I also advice you to learn more about networking and network programming. You should now at least how tcp protocol works. The protocol is quite trivial and small and hence, may save you a lot of time in future.

With netstat command you can easily see which programs ( (program_name,pid) tuple) are binded to which ports and what is the socket current state: TIME_WAIT, CLOSING, FIN_WAIT and so on.

A really good explanation of linux network configurations can be found https://serverfault.com/questions/212093/how-to-reduce-number-of-sockets-in-time-wait.

Not relevant with [ngClass] directive but I was also getting the same error as

Cannot read property 'remove' of undefined at...

and I thought to be the error in my [ngClass] condition but it turned out the property I was trying to access in the condition of [ngClass] was not initialized.

Like I had this in my typescript file

element: {type: string};

and In my [ngClass] I was using

[ngClass]="{'active', element.type === 'active'}"

and I was getting the error

Cannot read property 'type' of undefined at...

and the solution was to fix my property to

element: {type: string} = {type: 'active'};

Hope it helps somebody who is trying to match a condition of a property in [ngClass]

Try with the following code

View titleView = getWindow().findViewById(android.R.id.title);
    if (titleView != null) {
      ViewParent parent = titleView.getParent();
      if (parent != null && (parent instanceof View)) {
        View parentView = (View)parent;
        parentView.setBackgroundColor(Color.RED);
      }
    }

also use this link its very useful : http://nathanael.hevenet.com/android-dev-changing-the-title-bar-background/

If you add in the style

br{
    display: none;
}

Then this will work. Not sure if it will work in older versions of IE though.

You can use android:windowSoftInputMode="stateAlwaysHidden|adjustResize" in AndroidManifest.xml for your current activity, and use android:fitsSystemWindows="true" in styles or rootLayout.

To filter a list of dicts you can use the selectattr filter together with the equalto test:

network.addresses.private_man | selectattr("type", "equalto", "fixed")

The above requires Jinja2 v2.8 or later (regardless of Ansible version).

Ansible also has the tests match and search, which take regular expressions:

match will require a complete match in the string, while search will require a match inside of the string.

network.addresses.private_man | selectattr("type", "match", "^fixed$")

To reduce the list of dicts to a list of strings, so you only get a list of the addr fields, you can use the map filter:

... | map(attribute='addr') | list

Or if you want a comma separated string:

... | map(attribute='addr') | join(',')

Combined, it would look like this.

- debug: msg={{ network.addresses.private_man | selectattr("type", "equalto", "fixed") | map(attribute='addr') | join(',') }}

In case you want to use the Docker image as a "regular" Ubuntu installation, you can also run unminimize. This will install a lot more than ifconfig, so this might not be what you want.

In your Request class (that extends Request), override the getParams() method. You would do the same for headers, just override getHeaders().

If you look at PostWithBody class in TestRequest.java in Volley tests, you'll find an example. It goes something like this

public class LoginRequest extends Request<String> {

    // ... other methods go here

    private Map<String, String> mParams;

    public LoginRequest(String param1, String param2, Listener<String> listener, ErrorListener errorListener) {
        super(Method.POST, "http://test.url", errorListener);
        mListener = listener;
        mParams = new HashMap<String, String>();
        mParams.put("paramOne", param1);
        mParams.put("paramTwo", param2);

    }

    @Override
    public Map<String, String> getParams() {
        return mParams;
    }
}

Evan Charlton was kind enough to make a quick example project to show us how to use volley. https://github.com/evancharlton/folly/

echo $LINE | sed -e 's/12345678/'$replace'/g'

you can still use single quotes, but you have to "open" them when you want the variable expanded at the right place. otherwise the string is taken "literally" (as @paxdiablo correctly stated, his answer is correct as well)

raw.github.com/user/repository is no longer there

To link, href to source code in github, you have to use github link to raw source this way:

raw.githubusercontent.com/user/repository/master/file.extension

EXAMPLE

<html>
...
...
<head>    
<script src="https://raw.githubusercontent.com/amiahmadtouseef/tutorialhtmlfive/master/petdecider/script.js"></script>
...
</head>
<body>

unsorted_list.sort(key=lambda x: x[3])

Sharer.php no longer allows you to customize. The page you share will be scraped for OG Tags and that data will be shared.

To properly customize, use FB.UI which comes with the JS-SDK.

The elements of a sequence need to be indented at the same level. Assuming you want two jobs (A and B) each with an ordered list of key value pairs, you should use:

jobs:
 - - name: A
   - schedule: "0 0/5 * 1/1 * ? *"
   - - type: mongodb.cluster
     - config:
       - host: mongodb://localhost:27017/admin?replicaSet=rs
       - minSecondaries: 2
       - minOplogHours: 100
       - maxSecondaryDelay: 120
 - - name: B
   - schedule: "0 0/5 * 1/1 * ? *"
   - - type: mongodb.cluster
     - config:
       - host: mongodb://localhost:27017/admin?replicaSet=rs
       - minSecondaries: 2
       - minOplogHours: 100
       - maxSecondaryDelay: 120

Converting the sequences of (single entry) mappings to a mapping as @Tsyvarrev does is also possible, but makes you lose the ordering.

For me how it worked is, I have two executable versions of python so on pip install it was installing in one version but my executable path version is different so it failed, then I changed the path in sys's environment variable and installed in the executable version of python and it was able to identify the package from site-packages

Even if this is already answered (1 year ago) you could also let the fields be calculated automatically.

The HTML

    <tr>
        <td><input type="text" value="" ></td>
        <td><input type="text" class="class_name" placeholder="bla bla"/></td>
    </tr>
    <tr>
        <td><input type="text" value="" ></td>
        <td><input type="text" class="class_name" placeholder="bla bla."/></td>
    </tr>

The script

$(document).ready(function(){
                $(".class_name").each(function(){
                    $(this).keyup(function(){
                        calculateSum()
                        ;})
                    ;})
                ;}
                );
            function calculateSum(){
                var sum=0;
                $(".class_name").each(function(){
                    if(!isNaN(this.value) && this.value.length!=0){
                        sum+=parseFloat(this.value);
                    }
                    else if(isNaN(this.value)) {
                        alert("Maybe an alert if they type , instead of .");
                    }
                }
                );
                $("#sum").html(sum.toFixed(2));
                } 

Even using some of the comments above this took way longer to work out that should be necessary. Hopefully this example helps someone else.

Create a radio_button.xml in the drawable directory.

    <?xml version="1.0" encoding="utf-8"?>

<!-- An element which allows two drawable items to be listed.-->
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" android:drawable="@drawable/radio_button_checked" /> <!--pressed -->
    <item android:drawable="@drawable/radio_button_unchecked" /> <!-- Normal -->
</selector>

Then in the xml for the fragment should look something like

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

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">
<RadioGroup
android:layout_width="match_parent"
android:layout_height="match_parent">

<RadioButton

    android:id="@+id/radioButton1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="10dp"
    android:layout_weight="1"
    android:button="@drawable/radio_button"
    android:paddingLeft="10dp" />        
<RadioButton
    android:id="@+id/radioButton2"
    android:layout_marginLeft="10dp"
    android:paddingLeft="10dp"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:button="@drawable/radio_button" />

</RadioGroup>
    </LinearLayout>
</layout>

Implement your adapter Filterable:

public class vJournalAdapter extends ArrayAdapter<JournalModel> implements Filterable{
private ArrayList<JournalModel> items;
private Context mContext;
....

then create your Filter class:

private class JournalFilter extends Filter{

    @Override
    protected FilterResults performFiltering(CharSequence constraint) {
        FilterResults result = new FilterResults();
        List<JournalModel> allJournals = getAllJournals();
        if(constraint == null || constraint.length() == 0){

            result.values = allJournals;
            result.count = allJournals.size();
        }else{
            ArrayList<JournalModel> filteredList = new ArrayList<JournalModel>();
            for(JournalModel j: allJournals){
                if(j.source.title.contains(constraint))
                    filteredList.add(j);
            }
            result.values = filteredList;
            result.count = filteredList.size();
        }

        return result;
    }
    @SuppressWarnings("unchecked")
    @Override
    protected void publishResults(CharSequence constraint, FilterResults results) {
        if (results.count == 0) {
            notifyDataSetInvalidated();
        } else {
            items = (ArrayList<JournalModel>) results.values;
            notifyDataSetChanged();
        }
    }

}

this way, your adapter is Filterable, you can pass filter item to adapter's filter and do the work. I hope this will be helpful.

For me, the only way to reset the failed cherry-pick-attempt was

git reset --hard HEAD

2020 | SWIFT 5.1:

From STRING to URL:

let url = URL(fileURLWithPath: "//Users/Me/Desktop/Doc.txt")

From URL to STRING:

let a = String(describing: url)       // "file:////Users/Me/Desktop/Doc.txt"
let b = "\(url)"                      // "file:////Users/Me/Desktop/Doc.txt"
let c = url.absoluteString            // "file:////Users/Me/Desktop/Doc.txt"
let d = url.path                      // "/Users/Me/Desktop/Doc.txt" 

BUT value of d will be invisible due to debug process, so...

THE BEST SOLUTION:

let e = "\(url.path)"                 // "/Users/Me/Desktop/Doc.txt"

Try this with adjusting the date format.

long longtime = 1212580300;
SimpleDateFormat dateFormat = new SimpleDateFormat("MMddyyHHmm");
Date date = (Date) dateFormat.parseObject(longtime + "");
System.out.println(date);

Note: Check for 24 hours or 12 hours cycle.

just use simple css

.big-checkbox {width: 1.5rem; height: 1.5rem;top:0.5rem}

I think is because of this kind of lines (check "Thorn" and "Minus")

A C compiler itself won't provide you with GUI functionality, but there are plenty of libraries for that sort of thing. The most popular is probably GTK+, but it may be a little too complicated if you are just starting out and want to quickly get a GUI up and running.

For something a little simpler, I would recommend IUP. With it, you can use a simple GUI definition language called LED to layout controls (but you can do it with pure C, if you want to).

If you get your adb from Android Studio (which most will nowadays since Android is deprecated on Eclipse), your adb program will most likely be located here:

%USERPROFILE%\AppData\Local\Android\sdk\platform-tools

Where %USERPROFILE% represents something like C:\Users\yourName.

If you go into your computer's environmental variables and add %USERPROFILE%\AppData\Local\Android\sdk\platform-tools to the PATH (just copy-paste that line, even with the % --- it will work fine, at least on Windows, you don't need to hardcode your username) then it should work now. Open a new command prompt and type adb to check.

This is something I need all the time so I created a bash function for it. It's based on glenn jackman's answer.

Definition

Add this to your .bash_profile etc.

function regex { gawk 'match($0,/'$1'/, ary) {print ary['${2:-'0'}']}'; }

Usage

Capture regex for each line in file

$ cat filename | regex '.*'

Capture 1st regex capture group for each line in file

$ cat filename | regex '(.*)' 1

StringUtils is a utility class from Apache commons-lang (many libraries have it but this is the most common library). You need to download the jar and add it to your applications classpath.

The other answers are correct (with a caveat*). I add this answer simply to show an example usage:

- (void)getYourAffairsInOrder
{
    NSDate* methodStart = [NSDate date];  // Capture start time.

    // … Do some work …

    NSLog(@"DEBUG Method %s ran. Elapsed: %f seconds.", __func__, -([methodStart timeIntervalSinceNow]));  // Calculate and report elapsed time.
}

On the debugger console, you see something like this:

DEBUG Method '-[XMAppDelegate getYourAffairsInOrder]' ran. Elapsed: 0.033827 seconds.

*Caveat: As others mentioned, use NSDate to calculate elapsed time only for casual purposes. One such purpose might be common testing, crude profiling, where you just want a rough idea of how long a method is taking.

The risk is that the device's clock's current time setting could change at any moment because of network clock syncing. So NSDate time could jump forward or backward at any moment.

String.format("%1$,.2f", myDouble);

String.format automatically uses the default locale.

You can use JSON.stringify(object) with an object and I just wrote a function that'll recursively convert an array to an object, like this JSON.stringify(convArrToObj(array)), which is the following code (more detail can be found on this answer):

// Convert array to object
var convArrToObj = function(array){
    var thisEleObj = new Object();
    if(typeof array == "object"){
        for(var i in array){
            var thisEle = convArrToObj(array[i]);
            thisEleObj[i] = thisEle;
        }
    }else {
        thisEleObj = array;
    }
    return thisEleObj;
}

To make it more generic, you can override the JSON.stringify function and you won't have to worry about it again, to do this, just paste this at the top of your page:

// Modify JSON.stringify to allow recursive and single-level arrays
(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        return oldJSONStringify(convArrToObj(input));
    };
})();

And now JSON.stringify will accept arrays or objects! (link to jsFiddle with example)

Edit:

Here's another version that's a tad bit more efficient, although it may or may not be less reliable (not sure -- it depends on if JSON.stringify(array) always returns [], which I don't see much reason why it wouldn't, so this function should be better as it does a little less work when you use JSON.stringify with an object):

(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        if(oldJSONStringify(input) == '[]')
            return oldJSONStringify(convArrToObj(input));
        else
            return oldJSONStringify(input);
    };
})();

If this is from a SQL Server datebase you could issue this kind of query...

Select Top 1 DepartureTime From TrainSchedule where DepartureTime > 
GetUTCDate()
Order By DepartureTime ASC

GetDate() could also be used, not sure how dates are being stored.

I am not sure how the data is being stored and/or read.

In the package import org.apache.commons.lang.SerializationUtils; there is a method:

SerializationUtils.clone(Object);

Example:

this.myObjectCloned = SerializationUtils.clone(this.object);

Try putting this HTML snippet into your served document:

<img id="ItemPreview" src="">

Then, on JavaScript side, you can dynamically modify image's src attribute with so-called Data URL.

document.getElementById("ItemPreview").src = "data:image/png;base64," + yourByteArrayAsBase64;

Alternatively, using jQuery:

$('#ItemPreview').attr('src', `data:image/png;base64,${yourByteArrayAsBase64}`);

This assumes that your image is stored in PNG format, which is quite popular. If you use some other image format (e.g. JPEG), modify the MIME type ("image/..." part) in the URL accordingly.

There is a simple solution to this which worked for me on macOS Sierra. I did these two commands:

git pull --rebase git_url(Ex: https://github.com/username/reponame.git)
git push origin master

If it shows any fatal error regarding upstream after any future push then simply run :

git push --set-upstream origin master

Yahoo is very easy to use and provides customized data. Use the following page to learn more.

finance.yahoo.com/d/quotes.csv?s=AAPL+GOOG+MSFT=pder=.csv

WARNING - there are a few tutorials out there on the web that show you how to do this, but the region where you put in the stock symbols causes an error if you use it as posted. You will get a "MISSING FORMAT VALUE". The tutorials I found omits the commentary around GOOG.

Example URL for GOOG: http://download.finance.yahoo.com/d/quotes.csv?s=%40%5EDJI,GOOG&f=nsl1op&e=.csv

You could either explicitly name the columns you want to keep, like so:

keep = [a.id, a.julian_date, a.user_id, b.quan_created_money, b.quan_created_cnt]

Or in a more general approach you'd include all columns except for a specific one via a list comprehension. For example like this (excluding the id column from b):

keep = [a[c] for c in a.columns] + [b[c] for c in b.columns if c != 'id']

Finally you make a selection on your join result:

d = a.join(b, a.id==b.id, 'outer').select(*keep)

List<String> items = new ArrayList<>();
items.add("A");
items.add("B");
items.add("C");
items.add("D");
items.add("E");

//lambda
//Output : A,B,C,D,E
items.forEach(item->System.out.println(item));

//Output : C
items.forEach(item->{
    System.out.println(item);
    System.out.println(item.toLowerCase());
  }
});

Check chart.Boxplot from package PerformanceAnalytics. It lets you define the symbol to use for the mean of the distribution.

By default, the chart.Boxplot(data) command adds the mean as a red circle and the median as a black line.

Here is the output with sample data; MWE:

#install.packages(PerformanceAnalytics)    
library(PerformanceAnalytics)
chart.Boxplot(cars$speed)

Simplest of all solutions:

filtered_df = df[df['var2'].isnull()]

This filters and gives you rows which has only NaN values in 'var2' column.

The actual information represented by a boolean value in Java is one bit: 1 for true, 0 for false. However, the actual size of a boolean variable in memory is not precisely defined by the Java specification. See Primitive Data Types in Java.

The boolean data type has only two possible values: true and false. Use this data type for simple flags that track true/false conditions. This data type represents one bit of information, but its "size" isn't something that's precisely defined.

Be aware that the line-height approach fails if you have a long sentence in the span which breaks the line because there's not enough space. In this case, you would have two lines with a gap with the height of the N pixels specified in the property.

I stuck into it when I wanted to show an image with vertically centered text on its right side which works in a responsive web application. As a base I use the approach suggested by Eric Nickus and Felipe Tadeo.

If you want to achieve:

and this:

.container {_x000D_
    background: url( "https://i.imgur.com/tAlPtC4.jpg" ) no-repeat;_x000D_
    display: inline-block;_x000D_
    background-size: 40px 40px; /* image's size */_x000D_
    height: 40px; /* image's height */_x000D_
    padding-left: 50px; /* image's width plus 10 px (margin between text and image) */_x000D_
}_x000D_
_x000D_
.container span {_x000D_
    height: 40px; /* image's height */_x000D_
    display: table-cell;_x000D_
    vertical-align: middle;_x000D_
}

<span class="container">_x000D_
    <span>This is a centered sentence next to an image</span>_x000D_
</span>

Just use

filter_input(INPUT_METHOD_NAME, 'var_name') instead of $_INPUT_METHOD_NAME['var_name'] filter_input_array(INPUT_METHOD_NAME) instead of $_INPUT_METHOD_NAME

e.g

    $host= filter_input(INPUT_SERVER, 'HTTP_HOST');
    echo $host;

instead of

    $host= $_SERVER['HTTP_HOST'];
    echo $host;

And use

    var_dump(filter_input_array(INPUT_SERVER));

instead of

    var_dump($_SERVER);
