To continue a statement from one line to the next, type a space followed by the line-continuation character [the underscore character on your keyboard (_)].

You can break a line at an operator, list separator, or period.

yourTextfield.attributedPlaceholder = NSAttributedString(string: "your placeholder text",attributes: [NSForegroundColorAttributeName: UIColor.white])

To "loop" and take advantage of Spark's parallel computation framework, you could define a custom function and use map.

def customFunction(row):

   return (row.name, row.age, row.city)

sample2 = sample.rdd.map(customFunction)

or

sample2 = sample.rdd.map(lambda x: (x.name, x.age, x.city))

The custom function would then be applied to every row of the dataframe. Note that sample2 will be a RDD, not a dataframe.

Map may be needed if you are going to perform more complex computations. If you just need to add a simple derived column, you can use the withColumn, with returns a dataframe.

sample3 = sample.withColumn('age2', sample.age + 2)

Even if fileno(FILE *) may return a file descriptor, be VERY careful not to bypass stdio's buffer. If there is buffer data (either read or unflushed write), reads/writes from the file descriptor might give you unexpected results.

To answer one of the side questions, to convert a file descriptor to a FILE pointer, use fdopen(3)

You can check whether it exists and, if it does not exist, load it dynamically.

function loadScript(src) {
    return new Promise(function (resolve, reject) {
        var s;
        s = document.createElement('script');
        s.src = src;
        s.onload = resolve;
        s.onerror = reject;
        document.head.appendChild(s);
    });
}



async function load(){
if (!window.jQuery){
    await loadScript(`https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js`);
}

console.log(jQuery);

}

load();

It's probably because your SSH key has been removed/revoked. Make a new one and add it to your GitHub account.

Return as a tuple, e.g.

def foo (a):
    x=a
    y=a*2
    return (x,y)

You can also do it without modulus. Just reset your counter when it matches.

if($counter == 2) { // matches every 3 iterations
   echo 'image-file';
   $counter = 0; 
}

You can use reflection (reflect.TypeOf()) to get the type of something, and the value it gives (Type) has a string representation (String method) that you can print.

This XPath is specific to the code snippet you've provided. To select <child> with id as #grand you can write //child[@id='#grand'].

To get age //child[@id='#grand']/@age

Hope this helps

None of the above answers worked for me but I finally found what my issue was. Hopefully this will help someone down the line.

First run IIS Express from command prompt to validate that the site can or cannot be run

https://docs.microsoft.com/en-us/iis/extensions/using-iis-express/running-iis-express-from-the-command-line

Im my case, i got an error saying that C:\Windows\Microsoft.NET\Framework64\v4.0.30319\CONFIG\web.config had malformed xml on line 14. Looking at that line in the file it just said null null null null null etc.

The fix for me was to replace the web.config file with one from my coworkers. IMPORTANT you must get the file from someone running the same version ie if you are VS2015 get a copy from someone running VS2015. If you get it from someone running a different version you will see an error saying it could not load an assembly from the manifest.

Hopefully this helps someone that has tried all the suggestions above. I think the cause of this for me was updating from trial mode and adding a product key within VS2017

Chain selectors are not limited just to classes, you can do it for both classes and ids.

Classes

.classA.classB {
/*style here*/
}

Class & Id

.classA#idB {
/*style here*/
}

Id & Id

#idA#idB {
/*style here*/
}

All good current browsers support this except IE 6, it selects based on the last selector in the list. So ".classA.classB" will select based on just ".classB".

For your case

li.left.ui-class-selector {
/*style here*/
}

or

.left.ui-class-selector {
/*style here*/
}

I think the

best way

app.controller('ProductController', function($scope, $localStorage) {
    $scope.setSelectedProduct = function(selectedObj){
        $localStorage.selectedObj= selectedObj;
    };
});

Your cardController will be

app.controller('CartController', function($scope,$localStorage) { 
    $scope.selectedProducts = $localStorage.selectedObj;
    $localStorage.$reset();//to remove
});

You can also add

if($localStorage.selectedObj){
    $scope.selectedProducts = $localStorage.selectedObj;
}else{
    //redirect to select product using $location.url('/select-product')
}

you can give an <a> tag the visual behavior of a table cell:

HTML:

<table>
  <tr>
    <a href="...">Cell 1</a>
    <td>Cell 2</td>
  </tr>
</table>

CSS:

tr > a {
  display: table-cell;
}

I wasn't satisfied with the accepted answer so I created some scripts to do this for you available on Github. These should help anyone who wants to use git svn clone but doesn't want to clone the entire repository and doesn't want to hunt for a specific revision to clone from in the middle of the history (maybe you're cloning a bunch of repos). Here we can just clone the last N revisions:

Use git svn clone to clone the last 50 revisions

# -u    The SVN URL to clone
# -l    The limit of revisions
# -o    The output directory

./git-svn-cloneback.sh -u https://server/project/trunk -l 50 -o myproj --authors-file=svn-authors.txt

Find the previous N revision from an SVN repo

# -u    The SVN URL to clone
# -l    The limit of revisions

./svn-lookback.sh -u https://server/project/trunk -l 5     

You need to open the file again using open(), but this time passing 'w' to indicate that you want to write to the file. I would also recommend using with to ensure that the file will be closed when you are finished writing to it.

with open('Failed.txt', 'w') as f:
    for ip in [k for k, v in ips.iteritems() if v >=5]:
        f.write(ip)

Naturally you may want to include newlines or other formatting in your output, but the basics are as above.

The same issue with closing your file applies to the reading code. That should look like this:

ips = {}
with open('today','r') as myFile:
    for line in myFile:
        parts = line.split(' ')
        if parts[1] == 'Failure':
            if parts[0] in ips:
                ips[pars[0]] += 1
            else:
                ips[parts[0]] = 0

You can use a ternary operator

echo false ? 'true' : 'false';

`su -c "Your command right here" -s /bin/sh username`

The above command is correct, but on Red Hat if selinux is enforcing it will not allow cron to execute scripts as another user. example; execl: couldn't exec /bin/sh execl: Permission denied

I had to install setroubleshoot and setools and run the following to allow it:

yum install setroubleshoot setools
sealert -a /var/log/audit/audit.log
grep crond /var/log/audit/audit.log | audit2allow -M mypol
semodule -i mypol.p

Very old question, but in case someone else stumbles across it, I would recommend trying:

$j("html, body").stop(true, true).animate({
        scrollTop: $j('#main').offset().top 
}, 300);

The List class's constructor can convert an IQueryable for you:

public static List<TResult> ToList<TResult>(this IQueryable source)
{
    return new List<TResult>(source);
}

or you can just convert it without the extension method, of course:

var list = new List<T>(queryable);

        String input = "";
        int inputInteger = 0;
        BufferedReader br    = new BufferedReader(new InputStreamReader (System.in));

        System.out.println("Enter the radious: ");
        try {
            input = br.readLine();
            inputInteger = Integer.parseInt(input);
        } catch (NumberFormatException e) {
            System.out.println("Please Enter An Integer");
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        float area = (float) (3.14*inputInteger*inputInteger);
        System.out.println("Area = "+area);

String hql = "select userName from AccountInfo order by points desc 5";

This worked for me without using setmaxResults();

Just provide the max value in the last (in this case 5) without using the keyword limit. :P

I improved upon psycho brm's filterByData extension to jQuery.

Where the former extension searched on a key-value pair, with this extension you can additionally search for the presence of a data attribute, irrespective of its value.

(function ($) {

    $.fn.filterByData = function (prop, val) {
        var $self = this;
        if (typeof val === 'undefined') {
            return $self.filter(
                function () { return typeof $(this).data(prop) !== 'undefined'; }
            );
        }
        return $self.filter(
            function () { return $(this).data(prop) == val; }
        );
    };

})(window.jQuery);

Usage:

$('<b>').data('x', 1).filterByData('x', 1).length    // output: 1
$('<b>').data('x', 1).filterByData('x').length       // output: 1

There is nice tiny library to work with utf8 from c++: utfcpp

Add:

using System.Linq;

to the top of your file.

And then:

Car[] carList = ...
var carMake = 
    from item in carList
    where item.Model == "bmw" 
    select item.Make;

or if you prefer the fluent syntax:

var carMake = carList
    .Where(item => item.Model == "bmw")
    .Select(item => item.Make);

Things to pay attention to:

• The usage of item.Make in the select clause instead if s.Make as in your code.
• You have a whitespace between item and .Model in your where clause

The easiest way to output a single character is to simply use the putchar function. After all, that's it's sole purpose and it cannot do anything else. It cannot be simpler than that.

To just get the index column names df.index.names will work for both a single Index or MultiIndex as of the most recent version of pandas.

As someone who found this while trying to find the best way to get a list of index names + column names, I would have found this answer useful:

names = list(filter(None, df.index.names + df.columns.values.tolist()))

This works for no index, single column Index, or MultiIndex. It avoids calling reset_index() which has an unnecessary performance hit for such a simple operation. I'm surprised there isn't a built in method for this (that I've come across). I guess I run into needing this more often because I'm shuttling data from databases where the dataframe index maps to a primary/unique key, but is really just another column to me.

What about:

if (urldecode(trim($url)) == trim($url)) { $url_form = 'decoded'; }
  else { $url_form = 'encoded'; }

Will not work with double encoding but this is out of scope anyway I suppose?

Make sure your article:author data is a Facebook author URL. Unfortunately, that conflicts with what Pinterest is expecting. It's the best thing about standards, there are so many ways to implement them!

<meta property="article:author" content="https://www.facebook.com/mpatnode76">

But Pinterest wants to see something like this:

<meta property="article:author" content="Mike Patnode">

We ended up swapping the formats depending upon the user agent. Hopefully, that doesn't screw up your page cache. That fixed it for us.

Full disclosure. Found this here: https://surniaulula.com/2014/03/01/pinterest-articleauthor-incompatible-with-open-graph/

Just to add couple cents to this.

The "delete_by_query" mentioned at the top is still available as a plugin in elasticsearch 2.x.

Although in the latest upcoming version 5.x it will be replaced by "delete by query api"

Tensorflow includes also a sigmoid function: https://www.tensorflow.org/versions/r1.2/api_docs/python/tf/sigmoid

import tensorflow as tf

sess = tf.InteractiveSession()
x = 0.458
y = tf.sigmoid(x)

u = y.eval()
print(u)
# 0.6125396

I found this solution to be quite helpful. It uses C# 4.0 DynamicObject to wrap the ConfigurationManager. So instead of accessing values like this:

 WebConfigurationManager.AppSettings["PFUserName"]

you access them as a property:

dynamic appSettings = new AppSettingsWrapper();
Console.WriteLine(appSettings.PFUserName);  

EDIT: Adding code snippet in case link becomes stale:

public class AppSettingsWrapper : DynamicObject
{
     private NameValueCollection _items;

    public AppSettingsWrapper()
    {
        _items = ConfigurationManager.AppSettings;
    }

     public override bool TryGetMember(GetMemberBinder binder, out object result)
    {
        result = _items[binder.Name];
        return result != null;
    }
}

Use this:

Format(Now, "MMMM dd, yyyy")

None of this was really right for me. I wanted something that would purge all local branches that were tracking a remote branch, on origin, where the remote branch has been deleted (gone). I did not want to delete local branches that were never set up to track a remote branch (i.e.: my local dev branches). Also I wanted a simple one-liner that just uses git, or other simple CLI tools, rather than writing custom scripts. I ended up using a bit of grep and awk to make this simple command.

This is ultimately what ended up in my ~/.gitconfig:

[alias]
  prune-branches = !git remote prune origin && git branch -vv | grep ': gone]' | awk '{print $1}' | xargs -r git branch -D

Here is a git config --global ... command for easily adding this as git prune-branches:

git config --global alias.prune-branches '!git remote prune origin && git branch -vv | grep '"'"': gone]'"'"' | awk '"'"'{print $1}'"'"' | xargs -r git branch -d'

NOTE: In the config command, I use the -d option to git branch rather than -D, as I do in my actual config. I use -D because I don't want to hear Git complain about unmerged branches. You may want this functionality as well. If so, simply use -D instead of -d at the end of that config command.

It's really simple to fix the issue, however keep in mind that you should fork and commit your changes for each library you are using in their repositories to help others as well.

Let's say you have something like this in your code:

$str = "test";
echo($str{0});

since PHP 7.4 curly braces method to get individual characters inside a string has been deprecated, so change the above syntax into this:

$str = "test";
echo($str[0]);

Fixing the code in the question will look something like this:

public function getRecordID(string $zoneID, string $type = '', string $name = ''): string
{
    $records = $this->listRecords($zoneID, $type, $name);
    if (isset($records->result[0]->id)) {
        return $records->result[0]->id;
    }
    return false;
}

You should place Scanner input = new Scanner (System.in); into the main method rather than creating the input object outside.

Check if the element is a child of <html> via Node::contains():

const div = document.createElement('div');
document.documentElement.contains(div); //-> false

document.body.appendChild(div);
document.documentElement.contains(div); //-> true

I've covered this and more in is-dom-detached.

Jupyter has its own PATH variable, JUPYTER_PATH.

Adding this line to the .bashrc file worked for me:

export JUPYTER_PATH=<directory_for_your_module>:$JUPYTER_PATH

Java says that the default length of a JAVA array at the time of initialization will be 10.

private static final int DEFAULT_CAPACITY = 10;

But the size() method returns the number of inserted elements in the array, and since at the time of initialization, if you have not inserted any element in the array, it will return zero.

private int size;

public boolean add(E e) {
    ensureCapacityInternal(size + 1);  // Increments modCount!!
    elementData[size++] = e;
    return true;
}

public void add(int index, E element) {
    rangeCheckForAdd(index);
    ensureCapacityInternal(size + 1);  // Increments modCount!!
    System.arraycopy(elementData, index, elementData, index + 1,size - index);
    elementData[index] = element;
    size++;
}

The grammar of the language specifies that positional arguments appear before keyword or starred arguments in calls:

argument_list        ::=  positional_arguments ["," starred_and_keywords]
                            ["," keywords_arguments]
                          | starred_and_keywords ["," keywords_arguments]
                          | keywords_arguments

Specifically, a keyword argument looks like this: tag='insider trading!' while a positional argument looks like this: ..., exchange, .... The problem lies in that you appear to have copy/pasted the parameter list, and left some of the default values in place, which makes them look like keyword arguments rather than positional ones. This is fine, except that you then go back to using positional arguments, which is a syntax error.

Also, when an argument has a default value, such as price=None, that means you don't have to provide it. If you don't provide it, it will use the default value instead.

To resolve this error, convert your later positional arguments into keyword arguments, or, if they have default values and you don't need to use them, simply don't specify them at all:

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity)

# Fully positional:
order_id = kite.order_place(self, exchange, tradingsymbol, transaction_type, quantity, price, product, order_type, validity, disclosed_quantity, trigger_price, squareoff_value, stoploss_value, trailing_stoploss, variety, tag)

# Some positional, some keyword (all keywords at end):

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity, tag='insider trading!')

Best way I have found. Put #lgModal or some other variable name in your modal.

In your view:

<div bsModal #lgModal="bs-modal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-lg">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" (click)="lgModal.hide()" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
        <h4 class="modal-title">Large modal</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
    </div>
  </div>
</div>

In your component

import {Component, ViewChild, AfterViewInit} from '@angular/core';
import {CORE_DIRECTIVES} from '@angular/common';
// todo: change to ng2-bootstrap
import {MODAL_DIRECTIVES, BS_VIEW_PROVIDERS} from 'ng2-bootstrap/ng2-bootstrap';

export class ModalDemoComponent implements AfterViewInit{

  @ViewChild('childModal') public childModal: ModalDirective;
  @ViewChild('lgModal') public lgModal: ModalDirective;

  public showChildModal():void {
    this.childModal.show();
  }

  public hideChildModal():void {
    this.childModal.hide();
  }

  ngAfterViewInit() {
      this.lgModal.show();

This has been asked before here. The same answer I gave then still applies:

I had a similar need, and found this great little extension of the Twitter Bootstrap Popover by Lee Carmichael, called BootstrapX - clickover. He also has some usage examples here. Basically it will change the popover into an interactive component which will close when you click elsewhere on the page, or on a close button within the popover. This will also allow multiple popovers open at once and a bunch of other nice features.

One more alternative, in the case you are working with the Appstore, need "Entitlements" and as such need to link with an Apple-Framework.

For Entitlements to work (e.g. GameCenter) you need to have a "Link Binary with Libraries"-buildstep and then link with "GameKit.framework". CMake "injects" the libraries on a "low level" into the commandline, hence Xcode doesn't really know about it, and as such you will not get GameKit enabled in the Capabilities screen.

One way to use CMake and have a "Link with Binaries"-buildstep is to generate the xcodeproj with CMake, and then use 'sed' to 'search & replace' and add the GameKit in the way XCode likes it...

The script looks like this (for Xcode 6.3.1).

save this to "gamecenter.sed" and then "apply" it like this ( it changes your xcodeproj! )

sed -i.pbxprojbak -f gamecenter.sed myproject.xcodeproj/project.pbxproj

You might have to change the script-commands to fit your need.

Warning: it's likely to break with different Xcode-version as the project-format could change, the (hardcoded) unique number might not really by unique - and generally the solutions by other people are better - so unless you need to Support the Appstore + Entitlements (and automated builds), don't do this.

This is a CMake bug, see http://cmake.org/Bug/view.php?id=14185 and http://gitlab.kitware.com/cmake/cmake/issues/14185

You can also perform this action via SQL Server Management Studio.

Right click on your selected table -> Modify

Right click on the field you want to set as PK --> Set Primary Key

Under Column Properties set "Identity Specification" to Yes, then specify the starting value and increment value.

Then in the future if you want to be able to just script this kind of thing out you can right click on the table you just modified and select

"SCRIPT TABLE AS" --> CREATE TO

so that you can see for yourself the correct syntax to perform this action.

I always use 010 Editor to open huge files. It can handle 2 GB easily. I was manipulating files with 50 GB with 010 Editor :-)

It's commercial now, but it has a trial version.

Simply write to file string.Empty, when append is set to false in StreamWriter. I think this one is easiest to understand for beginner.

private void ClearFile()
{
    if (!File.Exists("TextFile.txt"))
        File.Create("TextFile.txt");

    TextWriter tw = new StreamWriter("TextFile.txt", false);
    tw.Write(string.Empty);
    tw.Close();
}

I also had the same error. In my case reason was I have created a update trigger on a table and under that trigger I am again updating the same table. And when I have removed the update statement from the trigger my problem has been resolved.

On http://blogs.msdn.com/b/brada/archive/2003/04/22/49997.aspx :

As David implies, there difference between String.Empty and "" are pretty small, but there is a difference. "" actually creates an object, it will likely be pulled out of the string intern pool, but still... while String.Empty creates no object... so if you are really looking for ultimately in memory efficiency, I suggest String.Empty. However, you should keep in mind the difference is so trival you will like never see it in your code...
As for System.String.Empty or string.Empty or String.Empty... my care level is low ;-)

This is the essential point although you don't need to make the code this messy. Instead you could just iterate through all the <td> and add the <input> with the attributes and finally put in the values.

function edit(el) {_x000D_
  el.childNodes[0].removeAttribute("disabled");_x000D_
  el.childNodes[0].focus();_x000D_
  window.getSelection().removeAllRanges();_x000D_
}_x000D_
function disable(el) {_x000D_
  el.setAttribute("disabled","");_x000D_
}

<table border>_x000D_
<tr>_x000D_
<td ondblclick="edit(this)"><input value="cell1" disabled onblur="disable(this)"></td>_x000D_
<td ondblclick="edit(this)"><input value="cell2" disabled onblur="disable(this)"></td>_x000D_
<td ondblclick="edit(this)"><input value="cell3" disabled onblur="disable(this)"></td>_x000D_
<td ondblclick="edit(this)"><input value="so forth..." disabled onblur="disable(this)">_x000D_
</td>_x000D_
</tr>_x000D_
</table>

It seems important to exactly match the format of the ISO string for TryParseExact to work. I guess Exact is Exact and this answer is obvious to most but anyway...

In my case, Reb.Cabin's answer doesn't work as I have a slightly different input as per my "value" below.

Value: 2012-08-10T14:00:00.000Z

There are some extra 000's in there for milliseconds and there may be more.

However if I add some .fff to the format as shown below, all is fine.

Format String: @"yyyy-MM-dd\THH:mm:ss.fff\Z"

In VS2010 Immediate Window:

DateTime.TryParseExact(value,@"yyyy-MM-dd\THH:mm:ss.fff\Z", CultureInfo.InvariantCulture,DateTimeStyles.AssumeUniversal, out d);

true

You may have to use DateTimeStyles.AssumeLocal as well depending upon what zone your time is for...

I think the above mentioned answer is correct.Because == is for testing whether two strings are the same object,whereas .equals() tests whether two strings have the same value.

Your Activity is receiving the callback as must have used:

mViewPagerCloth.setOnClickListener((YourActivityName)getActivity());

If you want your fragment to receive callback then do this:

mViewPagerCloth.setOnClickListener(this);

and implement onClickListener interface on Fragment

Verified the following on Virtualbox-5.0.24, Android_x86-4.4-r5. You get a screen similar to an 8" table. You can play around with the xxx in DPI=xxx, to change the resolution. xxx=100 makes it really small to match a real table exactly, but it may be too small when working with android in Virtualbox.

VBoxManage setextradata <VmName> "CustomVideoMode1" "440x680x16"

With the following appended to android kernel cmd:

UVESA_MODE=440x680 DPI=120

VB.Net has no such feature and it will not be coming in Visual Studio 2010. The feature that jirwin is refering is called implicit line continuation. It has to do with removing the _ from a multi-line statement or expression. This does remove the need to terminate a multiline string with _ but there is still no mult-line string literal in VB.

Example for multiline string

Visual Studio 2008

Dim x = "line1" & vbCrlf & _
        "line2"

Visual Studio 2010

Dim x = "line1" & vbCrlf & 
        "line2"

just try to remove the STATISTICS INDEXES linked to this COLUMN.

Best Regards.

Actually what made this so confusing is that the Beanstalk people stand behind their very non-standard use of Staging (it comes before development in their diagram, and it's not a mistake!

with JQuery .toggle() you can accomplish it easily

$( ".target" ).toggle();

You can use setTableId((short)100). I think this was changed in Java 5 so that numeric literals assigned to byte or short and within range for the target are automatically assumed to be the target type. That latest J2ME JVMs are derived from Java 4 though.

Try this It may be more appropriate for you

  #container {  _x000D_

    -webkit-transform: rotate(90deg);_x000D_
    -moz-transform: rotate(90deg);_x000D_
    -o-transform: rotate(90deg);_x000D_

This will automatically manage even rotation.

I think this would work...

Edit: This is wrong...The minimum SQL DateTime Value is 1/1/1753. My solution provides a datetime = 1/1/1900 00:00:00. Other answers have the correct minimum date...

You want to use a FrameLayout or a Merge layout to achieve this. Android dev guide has a great example of this here: Android Layout Tricks #3: Optimize by merging.

Follow instructions (steps 1 to 3 don't needed in windows):

1. Find mysql config to edit:

   /etc/mysql/my.cnf (Mysql 5.5)

   /etc/mysql/conf.d/mysql.cnf (Mysql 5.6+)

2. Find bind-address=127.0.0.1 in config file change bind-address=0.0.0.0 (you can set bind address to one of your interface ips or like me use 0.0.0.0)

3. Restart mysql service run on console: service restart mysql

4. Create a user with a safe password for remote connection. To do this run following command in mysql (if you are linux user to reach mysql console run mysql and if you set password for root run mysql -p):

   GRANT ALL PRIVILEGES 
    ON *.* TO 'remote'@'%' 
    IDENTIFIED BY 'safe_password' 
    WITH GRANT OPTION;`
   

Now you should have a user with name of user and password of safe_password with capability of remote connect.

If the shell scripts start with #!/bin/bash, they will always run with bash from /bin. If they however start with #!/usr/bin/env bash, they will search for bash in $PATH and then start with the first one they can find.

Why would this be useful? Assume you want to run bash scripts, that require bash 4.x or newer, yet your system only has bash 3.x installed and currently your distribution doesn't offer a newer version or you are no administrator and cannot change what is installed on that system.

Of course, you can download bash source code and build your own bash from scratch, placing it to ~/bin for example. And you can also modify your $PATH variable in your .bash_profile file to include ~/bin as the first entry (PATH=$HOME/bin:$PATH as ~ will not expand in $PATH). If you now call bash, the shell will first look for it in $PATH in order, so it starts with ~/bin, where it will find your bash. Same thing happens if scripts search for bash using #!/usr/bin/env bash, so these scripts would now be working on your system using your custom bash build.

One downside is, that this can lead to unexpected behavior, e.g. same script on the same machine may run with different interpreters for different environments or users with different search paths, causing all kind of headaches.

The biggest downside with env is that some systems will only allow one argument, so you cannot do this #!/usr/bin/env <interpreter> <arg>, as the systems will see <interpreter> <arg> as one argument (they will treat it as if the expression was quoted) and thus env will search for an interpreter named <interpreter> <arg>. Note that this is not a problem of the env command itself, which always allowed multiple parameters to be passed through but with the shebang parser of the system that parses this line before even calling env. Meanwhile this has been fixed on most systems but if your script wants to be ultra portable, you cannot rely that this has been fixed on the system you will be running.

It can even have security implications, e.g. if sudo was not configured to clean environment or $PATH was excluded from clean up. Let me demonstrate this:

Usually /bin is a well protected place, only root is able to change anything there. Your home directory is not, though, any program you run is able to make changes to it. That means malicious code could place a fake bash into some hidden directory, modify your .bash_profile to include that directory in your $PATH, so all scripts using #!/usr/bin/env bash will end up running with that fake bash. If sudo keeps $PATH, you are in big trouble.

E.g. consider a tool creates a file ~/.evil/bash with the following content:

#!/bin/bash

if [ $EUID -eq 0 ]; then
  echo "All your base are belong to us..."
  # We are root - do whatever you want to do
fi

/bin/bash "$@"

Let's make a simple script sample.sh:

#!/usr/bin/env bash

echo "Hello World"

Proof of concept (on a system where sudo keeps $PATH):

$ ./sample.sh
Hello World

$ sudo ./sample.sh
Hello World

$ export PATH="$HOME/.evil:$PATH"

$ ./sample.sh
Hello World

$ sudo ./sample.sh
All your base are belong to us...
Hello World

Usually the classic shells should all be located in /bin and if you don't want to place them there for whatever reason, it's really not an issue to place a symlink in /bin that points to their real locations (or maybe /bin itself is a symlink), so I would always go with #!/bin/sh and #!/bin/bash. There's just too much that would break if these wouldn't work anymore. It's not that POSIX would require these position (POSIX does not standardize path names and thus it doesn't even standardize the shebang feature at all) but they are so common, that even if a system would not offer a /bin/sh, it would probably still understand #!/bin/sh and know what to do with it and may it only be for compatibility with existing code.

But for more modern, non standard, optional interpreters like Perl, PHP, Python, or Ruby, it's not really specified anywhere where they should be located. They may be in /usr/bin but they may as well be in /usr/local/bin or in a completely different hierarchy branch (/opt/..., /Applications/..., etc.). That's why these often use the #!/usr/bin/env xxx shebang syntax.

I had problem too. I switced Port but couldn't start on 8012.

Skype was involved becouse it had the same port - 80. And it couldn't let apache change it's port.

So just restart computer and Before turning on any other programs Open xampp first change port let's say from 80 to 8000 or 8012 on these lines in httpd.conf

Listen 80
ServerName localhost:80

Restart xampp, Start apache, check localhost.

Just an observation I just made while building naive code on OSX with cmake:

cmake ... -DBUILD_SHARED_LIBS=OFF ...

creates .so files

while

cmake ... -DBUILD_SHARED_LIBS=ON ...

creates .dynlib files.

Perhaps this helps anyone.

If you can't use the delay method as Robert Harvey suggested, you can use setTimeout.

Eg.

setTimeout(function() {$("#test").animate({"top":"-=80px"})} , 1500); // delays 1.5 sec
setTimeout(function() {$("#test").animate({"opacity":"0"})} , 1500 + 1000); // delays 1 sec after the previous one

From the documentation (MySQL 8) :

      Type | Maximum length

  TINYTEXT |           255 (2 8−1) bytes
      TEXT |        65,535 (216−1) bytes = 64 KiB
MEDIUMTEXT |    16,777,215 (224−1) bytes = 16 MiB
  LONGTEXT | 4,294,967,295 (232−1) bytes =  4 GiB

Note that the number of characters that can be stored in your column will depend on the character encoding.

for element in somelist:
    do_action(element)
somelist[:] = (x for x in somelist if not check(x))

If you really need to do it in one pass without copying the list

i=0

    element = somelist[i] 
    do_action(element)
    if check(element):
        del somelist[i]
    else:
        i+=1

I have a small script interruptableloop.py that runs the code at an interval (default 1sec), it pumps out a message to the screen while it's running, and traps an interrupt signal that you can send with CTL-C:

#!/usr/bin/python3
from interruptableLoop import InterruptableLoop

loop=InterruptableLoop(intervalSecs=1) # redundant argument
while loop.ShouldContinue():
   # some python code that I want 
   # to keep on running
   pass

When you run the script and then interrupt it you see this output, (the periods pump out on every pass of the loop):

[py36]$ ./interruptexample.py

This answer comes a little bit late, but I just was in a similar need.

Observing the comments written by @ganaraj in the question, One use case I was in the need of is, passing a classname via a directive attribute to be added to a ng-repeat li tag in the template.

For example, use the directive like this:

<my-directive class2add="special-class" />

And get the following html:

<div>
    <ul>
       <li class="special-class">Item 1</li>
       <li class="special-class">Item 2</li>
    </ul>
</div>

The solution found here applied with templateUrl, would be:

app.directive("myDirective", function() {
    return {
        template: function(element, attrs){
            return '<div><ul><li ng-repeat="item in items" class="'+attrs.class2add+'"></ul></div>';
        },
        link: function(scope, element, attrs) {
            var list = element.find("ul");
        }
    }
});

Just tried it successfully with AngularJS 1.4.9.

Hope it helps.

Warning, using the batch file for, tokens, and delims capability on unknown text input can be a disaster due to the special interpretation of chars like &, !, <, etc. Such methods should be reserved for only predictable text.

You can assign int to char directly.

int a = 65;
char c = a;
printf("%c", c);

In fact this will also work.

printf("%c", a);  // assuming a is in valid range

Simply add [] to those names like

 <input type="text" class="form-control" placeholder="Titel" name="levels[level][]">
 <input type="text" class="form-control" placeholder="Titel" name="levels[build_time][]">

Take that template and then you can add those even using a loop.

Then you can add those dynamically as much as you want, without having to provide an index. PHP will pick them up just like your expected scenario example.

Edit

Sorry I had braces in the wrong place, which would make every new value as a new array element. Use the updated code now and this will give you the following array structure

levels > level (Array)
levels > build_time (Array)

Same index on both sub arrays will give you your pair. For example

echo $levels["level"][5];
echo $levels["build_time"][5];

I don't know if javaw will write to the %errorlevel% variable, but it might.

echo %errorlevel% after you run it directly to see.

Other than that, you can pipe the output of javaw to a file, then use find to see what the results were. Without knowing the output of it, I can't really help you with that.

Create a xml file in drawable folder like below

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" android:padding="10dp">
    <!-- you can use any color you want I used here gray color-->
    <solid android:color="#ABABAB"/> 
    <corners android:radius="10dp"/>
</shape>

Apply this as background to button you want make corners round.

Or you can use separate radius for every corner like below

android:bottomRightRadius="10dp"
android:bottomLeftRadius="10dp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp"

I agree with aberrant80.

For enums, I test them only when they actually have methods in them. If it's a pure value-only enum like your example, I'd say don't bother.

But since you're keen on testing it, going with your second option is much better than the first. The problem with the first is that if you use an IDE, any renaming on the enums would also rename the ones in your test class.

I would expand on it by adding that unit testings an Enum can be very useful. If you work in a large code base, build time starts to mount up and a unit test can be a faster way to verify functionality (tests only build their dependencies). Another really big advantage is that other developers cannot change the functionality of your code unintentionally (a huge problem with very large teams).

And with all Test Driven Development, tests around an Enums Methods reduce the number of bugs in your code base.

Simple Example

public enum Multiplier {
    DOUBLE(2.0),
    TRIPLE(3.0);

    private final double multiplier;

    Multiplier(double multiplier) {
        this.multiplier = multiplier;
    }

    Double applyMultiplier(Double value) {
        return multiplier * value;
    }

}

public class MultiplierTest {

    @Test
    public void should() {
        assertThat(Multiplier.DOUBLE.applyMultiplier(1.0), is(2.0));
        assertThat(Multiplier.TRIPLE.applyMultiplier(1.0), is(3.0));
    }
}

jq '.users[]|.first,.last' | paste - -

OK.

When I double click this file I get the following error

Sounds like you're double-clicking/running a .js file, which will attempt to run the script outside the browser, like a command line script. And that would explain this error:

Windows Script Host Error: 'window' is not defined Code: 800A1391

... not an error you'll see in a browser. And of course, the browser is what supplies the window object.

ADDENDUM: As a course of action, I'd suggest opening the relevant HTML file and taking a peek at the console. If you don't see anything there, it's likely your window.onload definition is simply being hit after the browser fires the window.onload event.

The flexbox grid should do what you want. You're not clear as to what limitation you ran into, so it's hard to address your specifics.

DTO is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.

• DTO should only contain private fields for your data, getters, setters, and constructors.
• DTO is not recommended to add business logic methods to such classes, but it is OK to add some util methods.

DAO is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).

Here is an example of how the DAO and DTO interfaces would look like:

interface PersonDTO {
    String getName();
    void setName(String name);
    //.....
}

interface PersonDAO {
    PersonDTO findById(long id);
    void save(PersonDTO person);
    //.....
}

The MVC is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.

As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

I will trim the end for unwanted characters:

s = s.TrimEnd(' ', '!');

To ensure it works even with more spaces. Or better if you want to ensure it works always, since the input text seems to come from the user:

Regex r = new Regex(@"(?'purged'(\w|\s)+\w)");
Match m = r.Match("Hello Marco   !!");
if (m.Success)
{
    string result = m.Groups["purged"].Value;
}

With this you are safer. A purge based on the fact the last two characters has to be removed is too weak.

Well, I believe that I've solved the password configuration 'issue' - WampServer 2.2 - Windows 7.

The three steps that I did:

1. In the MySQL console set a new password. To make that: mysqladmin -u root password 'your_password'

2. In phpMyAdmin click in users and set the same password to the user root.

3. Finally, set your new password in the config.inc.php. Don't change anything else in this file.

This worked for me. Good luck!

1. Open your files in windows notebook
2. Change the encoding to be an UTF-8 encoding
3. Save your file
4. Try again! :O)

My simple solution is to style hr with css to have zero top & bottom margins, zero border, 1 pixel height and contrasting background color. This can be done by setting the style directly or by defining a class, for example, like:

.thin_hr {
margin-top:0;
margin-bottom:0;
border:0;
height:1px;
background-color:black;
}

This post helped me today, but I had to experiment to do what I needed. Here is what I found.

Should you want to add more complex time periods, for example 1 year and 15 days, you can use

UPDATE tablename SET datefieldname = curdate() + INTERVAL 15 DAY + INTERVAL 1 YEAR;

I found that using DATE_ADD doesn't allow for adding more than one interval. And there is no YEAR_DAYS interval keyword, though there are others that combine time periods. If you are adding times, use now() rather than curdate().

The problem is not with the splitting but rather with the WriteLine. A \n in a string printed with WriteLine will produce an "extra" line.

Example

var text = 
  "somet interesting text\n" +
  "some text that should be in the same line\r\n" +
  "some text should be in another line";

string[] stringSeparators = new string[] { "\r\n" };
string[] lines = text.Split(stringSeparators, StringSplitOptions.None);
Console.WriteLine("Nr. Of items in list: " + lines.Length); // 2 lines
foreach (string s in lines)
{
   Console.WriteLine(s); //But will print 3 lines in total.
}

To fix the problem remove \n before you print the string.

Console.WriteLine(s.Replace("\n", ""));

Check you class name first. It should be p1 as per your batch file instruction. And then check you package of that class, if it is inside any package, specify when you run.

If package is x.y

java x.y.p1

Yes, use the rendered attribute.

<h:form rendered="#{some boolean condition}">

You usually tie it to the model rather than letting the model grab the component and manipulate it.

E.g.

<h:form rendered="#{bean.booleanValue}" />
<h:form rendered="#{bean.intValue gt 10}" />
<h:form rendered="#{bean.objectValue eq null}" />
<h:form rendered="#{bean.stringValue ne 'someValue'}" />
<h:form rendered="#{not empty bean.collectionValue}" />
<h:form rendered="#{not bean.booleanValue and bean.intValue ne 0}" />
<h:form rendered="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />

Note the importance of keyword based EL operators such as gt, ge, le and lt instead of >, >=, <= and < as angle brackets < and > are reserved characters in XML. See also this related Q&A: Error parsing XHTML: The content of elements must consist of well-formed character data or markup.

As to your specific use case, let's assume that the link is passing a parameter like below:

<a href="page.xhtml?form=1">link</a>

You can then show the form as below:

<h:form rendered="#{param.form eq '1'}">

(the #{param} is an implicit EL object referring to a Map representing the request parameters)

Most computers store data in 8-bit binary format, but this is not a requirement. Some machines and transmission media can only handle 7 bits (or maybe even lesser) at a time. Such a medium would interpret the stream in multiples of 7 bits, so if you were to send 8-bit data, you won't receive what you expect on the other side. Base-64 is just one way to solve this problem: you encode the input into a 6-bit format, send it over your medium and decode it back to 8-bit format at the receiving end.

If your string constraint is not just one string you can drop those corresponding rows with:

df = df[~df['your column'].isin(['list of strings'])]

The above will drop all rows containing elements of your list

You could add

cd /some/directory/somewhere/named/Foo

to your .bashrc file (or .profile or whatever you call it) at the other host. That way, no matter what you do or where you ssh from, whenever you log onto that server, it will cd to the proper directory for you, and all you have to do is use ssh like normal.

Of curse, rogeriopvl's solution works too, but it's a tad bit more verbose, and you have to remember to do it every time (unless you make an alias) so it seems a bit less "fun".

From the main menu, select File | Manage IDE Settings | Restore Default Settings.

Alternatively, press Shift twice and type Restore default settings

In SSMS in the Object Explorer, right click on the database, right-click and pick "Tasks" and then "Generate Scripts".

This will allow you to generate scripts for a single or all tables, and one of the options is "Script Data". If you set that to TRUE, the wizard will generate a script with INSERT INTO () statement for your data.

If using 2008 R2 or 2012 it is called something else, see screenshot below this one

2008 R2 or later eg 2012

Select "Types of Data to Script" which can be "Data Only", "Schema and Data" or "Schema Only" - the default).

And then there's a "SSMS Addin" Package on Codeplex (including source) which promises pretty much the same functionality and a few more (like quick find etc.)

The accepted answer uses REGEX and you cannot create an alias command with REGEX, you have to put it into a shell script, I'm using Amazon Linux 2 and did the following:

1. I put the accepted answer code into a file using :

   sudo vim find.sh

add this code:

find ./ -type f | perl -ne 'print $1 if m/\.([^.\/]+)$/' | sort -u

save the file by typing: :wq!

2. sudo vim ~/.bash_profile

3. alias getext=". /path/to/your/find.sh"

4. :wq!

5. . ~/.bash_profile

I don't agree with the way that Bootstrap uses fade in (as seen in their documentation - http://v4-alpha.getbootstrap.com/components/alerts/), and my suggestion is to avoid the class names fade and in, and to avoid that pattern in general (which is currently seen in the top-rated answer to this question).

(1) The semantics are wrong - transitions are temporary, but the class names live on. So why should we name our classes fade and fade in? It should be faded and faded-in, so that when developers read the markup, it's clear that those elements were faded or faded-in. The Bootstrap team has already done away with hide for hidden, why is fade any different?

(2) Using 2 classes fade and in for a single transition pollutes the class space. And, it's not clear that fade and in are associated with one another. The in class looks like a completely independent class, like alert and alert-success.

The best solution is to use faded when the element has been faded out, and to replace that class with faded-in when the element has been faded in.

Alert Faded

So to answer the question. I think the alert markup, style, and logic should be written in the following manner. Note: Feel free to replace the jQuery logic, if you're using vanilla javascript.

HTML

<div id="saveAlert" class="alert alert-success">
  <a class="close" href="#">×</a>
  <p><strong>Well done!</strong> You successfully read this alert message.</p>
</div>

CSS

.faded {
  opacity: 0;
  transition: opacity 1s;
}

JQuery

$('#saveAlert .close').on('click', function () {

  $("#saveAlert")
    .addClass('faded');

});

There's a nice way to eject webpack.config.js from angular-cli. Just run:

$ ng eject

This will generate webpack.config.js in the root folder of your project, and you're free to configure it the way you want. The downside of this is that build/start scripts in your package.json will be replaced with the new commands and instead of

$ ng serve

you would have to do something like

$ npm run build & npm run start

This method should work in all the recent versions of angular-cli (I personally tried a few, with the oldest being 1.0.0-beta.21, and the latest 1.0.0-beta.32.3)

A plugin is probably your best option. Look in the wordpress plugins directory or google to see if you can find one. I found the one below and that seemed to work perfect.

This one seems to do exactly what you are after

Does it really have to be a thread, or can it be a task too?

if so, the easiest way is:

Task.Factory.StartNew(() => SecondFoo())

Although you can have logat on a real device too, if you need to use an emulator try transferring the images through the Android Device Monitor, accessible from the toolbar in Android Studio (it's in eclipse too, of course).

Once you select the device from ADM, you can see the folders tree and copy things inside

In PyCharm go to

1. File ? Settings, or use Ctrl + Alt + S
2. < project name > ? Project Interpreter ? gear symbol ? Add Local
3. navigate to C:\Miniconda3\envs\my_env\python.exe, where my_env is the environment you want to use

Alternatively, in step 3 use C:\Miniconda3\python.exe if you did not create any further environments (if you never invoked conda create -n my_env python=3).

You can get a list of your current environments with conda info -e and switch to one of them using activate my_env.

404 with Content/Body

res.writeHead(404, {'Content-Type': 'text/plain'});                    // <- redirect
res.write("Looked everywhere, but couldn't find that page at all!\n"); // <- content!
res.end();                                                             // that's all!

Redirect to Https

res.writeHead(302, {'Location': 'https://example.com' + req.url});
res.end();

Just consider where you use this (e.g. only for http request), so you don't get endless redirects ;-)

I wrote my own FactoryBean which instantiates an ObjectMapper (simplified version):

 public class ObjectMapperFactoryBean implements FactoryBean<ObjectMapper>{

        @Override
        public ObjectMapper getObject() throws Exception {
                ObjectMapper mapper = new ObjectMapper();
                mapper.getSerializationConfig().setSerializationInclusion(JsonSerialize.Inclusion.NON_NULL);
                return mapper;
        }

        @Override
        public Class<?> getObjectType() {
                return ObjectMapper.class;
        }

        @Override
        public boolean isSingleton() {
                return true;
        }

}

And the usage in the spring configuration:

<bean
    class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
    <property name="messageConverters">
        <list>
            <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
                <property name="objectMapper" ref="jacksonObjectMapper" />
            </bean>
        </list>
    </property>
</bean>

I believe you are looking for -maxdepth 1.

origin is the default alias to the URL of your remote repository.

Switch ruby version from 1.9 to 2.2 with rvm did the job for me

Make a javascript function

function addSampleTextInInputBox(message) {
    //set value in input box
    document.getElementById('textInput').value = message + "";
    //or show an alert
    //window.alert(message);
}

Then simply call in your table row button click

<td class="center">
    <a class="btn btn-success" onclick="addSampleTextInInputBox('<?php echo $row->message; ?>')" title="Add" data-toggle="tooltip" title="Add">
        <span class="fa fa-plus"></span>
    </a>
</td>

In my case this was a syntax issue in the .yml file. I had:

@Value("${spring.kafka.bootstrap-servers}")
public List<String> BOOTSTRAP_SERVERS_LIST;

and the list in my .yml file:

bootstrap-servers:
  - s1.company.com:9092
  - s2.company.com:9092
  - s3.company.com:9092

was not reading into the @Value-annotated field. When I changed the syntax in the .yml file to:

bootstrap-servers >
  s1.company.com:9092
  s2.company.com:9092
  s3.company.com:9092

it worked fine.

.so files are dynamic libraries. The suffix stands for "shared object", because all the applications that are linked with the library use the same file, rather than making a copy in the resulting executable.

.a files are static libraries. The suffix stands for "archive", because they're actually just an archive (made with the ar command -- a predecessor of tar that's now just used for making libraries) of the original .o object files.

.la files are text files used by the GNU "libtools" package to describe the files that make up the corresponding library. You can find more information about them in this question: What are libtool's .la file for?

Static and dynamic libraries each have pros and cons.

Static pro: The user always uses the version of the library that you've tested with your application, so there shouldn't be any surprising compatibility problems.

Static con: If a problem is fixed in a library, you need to redistribute your application to take advantage of it. However, unless it's a library that users are likely to update on their own, you'd might need to do this anyway.

Dynamic pro: Your process's memory footprint is smaller, because the memory used for the library is amortized among all the processes using the library.

Dynamic pro: Libraries can be loaded on demand at run time; this is good for plugins, so you don't have to choose the plugins to be used when compiling and installing the software. New plugins can be added on the fly.

Dynamic con: The library might not exist on the system where someone is trying to install the application, or they might have a version that's not compatible with the application. To mitigate this, the application package might need to include a copy of the library, so it can install it if necessary. This is also often mitigated by package managers, which can download and install any necessary dependencies.

Dynamic con: Link-Time Optimization is generally not possible, so there could possibly be efficiency implications in high-performance applications. See the Wikipedia discussion of WPO and LTO.

Dynamic libraries are especially useful for system libraries, like libc. These libraries often need to include code that's dependent on the specific OS and version, because kernel interfaces have changed. If you link a program with a static system library, it will only run on the version of the OS that this library version was written for. But if you use a dynamic library, it will automatically pick up the library that's installed on the system you run on.

Like everyone said, do not screw around with prototype. Instead, simply write a function to do so. Here is my version with lodash:

import each from 'lodash/each';
import get from 'lodash/get';

const myFilteredResults = results => {
  const filteredResults = [];

  each(results, obj => {
    // filter by whatever logic you want.

    // sample example
    const someBoolean = get(obj, 'some_boolean', '');

    if (someBoolean) {
      filteredResults.push(obj);
    }
  });

  return filteredResults;
};

Bottom Line

Your code has retrieved data (entities) via entity-framework with lazy-loading enabled and after the DbContext has been disposed, your code is referencing properties (related/relationship/navigation entities) that was not explicitly requested.

More Specifically

The InvalidOperationException with this message always means the same thing: you are requesting data (entities) from entity-framework after the DbContext has been disposed.

A simple case:

(these classes will be used for all examples in this answer, and assume all navigation properties have been configured correctly and have associated tables in the database)

public class Person
{
  public int Id { get; set; }
  public string name { get; set; }
  public int? PetId { get; set; }
  public Pet Pet { get; set; }
}

public class Pet 
{
  public string name { get; set; }
}

using (var db = new dbContext())
{
  var person = db.Persons.FirstOrDefaultAsync(p => p.id == 1);
}

Console.WriteLine(person.Pet.Name);

The last line will throw the InvalidOperationException because the dbContext has not disabled lazy-loading and the code is accessing the Pet navigation property after the Context has been disposed by the using statement.

Debugging

How do you find the source of this exception? Apart from looking at the exception itself, which will be thrown exactly at the location where it occurs, the general rules of debugging in Visual Studio apply: place strategic breakpoints and inspect your variables, either by hovering the mouse over their names, opening a (Quick)Watch window or using the various debugging panels like Locals and Autos.

If you want to find out where the reference is or isn't set, right-click its name and select "Find All References". You can then place a breakpoint at every location that requests data, and run your program with the debugger attached. Every time the debugger breaks on such a breakpoint, you need to determine whether your navigation property should have been populated or if the data requested is necessary.

Ways to Avoid

Disable Lazy-Loading

public class MyDbContext : DbContext
{
  public MyDbContext()
  {
    this.Configuration.LazyLoadingEnabled = false;
  }
}

Pros: Instead of throwing the InvalidOperationException the property will be null. Accessing properties of null or attempting to change the properties of this property will throw a NullReferenceException.

How to explicitly request the object when needed:

using (var db = new dbContext())
{
  var person = db.Persons
    .Include(p => p.Pet)
    .FirstOrDefaultAsync(p => p.id == 1);
}
Console.WriteLine(person.Pet.Name);  // No Exception Thrown

In the previous example, Entity Framework will materialize the Pet in addition to the Person. This can be advantageous because it’s a single call the the database. (However, there can also be huge performance problems depending on the number of returned results and the number of navigation properties requested, in this instance, there would be no performance penalty because both instances are only a single record and a single join).

or

using (var db = new dbContext())
{
  var person = db.Persons.FirstOrDefaultAsync(p => p.id == 1);

  var pet = db.Pets.FirstOrDefaultAsync(p => p.id == person.PetId);
}
Console.WriteLine(person.Pet.Name);  // No Exception Thrown

In the previous example, Entity Framework will materialize the Pet independently of the Person by making an additional call to the database. By default, Entity Framework tracks objects it has retrieved from the database and if it finds navigation properties that match it will auto-magically populate these entities. In this instance because the PetId on the Person object matches the Pet.Id, Entity Framework will assign the Person.Pet to the Pet value retrieved, before the value is assigned to the pet variable.

I always recommend this approach as it forces programmers to understand when and how code is request data via Entity Framework. When code throws a null reference exception on a property of an entity, you can almost always be sure you have not explicitly requested that data.

In Safari, you can use synchronous requests to avoid the browser to display the popup. Of course, synchronous requests should only be used in this case to check user credentials... You can use a such request before sending the actual request which may cause a bad user experience if the content (sent or received) is quite heavy.

    var xmlhttp=new XMLHttpRequest;
    xmlhttp.withCredentials=true;
    xmlhttp.open("POST",<YOUR UR>,false,username,password);

    xmlhttp.setRequestHeader('X-Requested-With', 'XMLHttpRequest');

Here's how

int i = Math.Abs(386792);
while(i >= 10)
    i /= 10;

and i will contain what you need

Use jquery change event

Description: Bind an event handler to the "change" JavaScript event, or trigger that event on an element.

An example

$("input[type='text']").change( function() {
  // your code
});

The advantage that .change has over .keypress , .focus , .blur is that .change event will fire only when input has changed

You can use the following example to store a query result in a variable using PL/pgSQL:

 select * into demo from maintenanceactivitytrack ; 
    raise notice'p_maintenanceid:%',demo;

What I do is something just a little bit different from @Chase answer:

var employees = {};

// ...and then:
employees.accounting = new Array();

for (var i = 0; i < someArray.length; i++) {
    var temp_item = someArray[i];

    // Maybe, here make something like:
    // temp_item.name = 'some value'

    employees.accounting.push({
        "firstName" : temp_item.firstName,
        "lastName"  : temp_item.lastName,
        "age"       : temp_item.age
    });
}

And that work form me!

I hope it could be useful for some body else!

You could use grep to pull them out.

grep -o '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}' file.txt

As mentioned already, you can use the arguments object to retrieve a variable number of function parameters.

If you want to call another function with the same arguments, use apply. You can even add or remove arguments by converting arguments to an array. For example, this function inserts some text before logging to console:

log() {
    let args = Array.prototype.slice.call(arguments);
    args = ['MyObjectName', this.id_].concat(args);
    console.log.apply(console, args);
}

There is already answer with Error Control Operator but it lacks of explanation. You can use @ operator with every expression and it hides errors (except of Fatal Errors).

@$test['test']; //PHP Notice:  Undefined variable: test

@(14/0); // PHP Warning:  Division by zero

//This is not working. You can't hide Fatal Errors this way.
@customFuntion(); // PHP Fatal error:  Uncaught Error: Call to undefined function customFuntion()

For debugging it's fast and perfect method. But you should never ever use it on production nor permanent include in your local version. It will give you a lot of unnecessary irritation.

You should consider instead:

1. Error reporting settings as mentioned in accepted answer.

error_reporting(E_ERROR | E_PARSE);

or from PHP INI settings

ini_set('display_errors','Off');

2. Catching exceptions

try {
    $var->method();
} catch (Error $e) {
    // Handle error
    echo $e->getMessage();
}

Here is a good way to do it.

from django.utils.datastructures import MultiValueDictKeyError
try:
    message = 'You submitted: %r' % request.GET['q']
except MultiValueDictKeyError:
    message = 'You submitted nothing!'

You don't need to check again if q is in GET request. The call in the QueryDict.get already does that to you.

I remember one time when I stumbled upon this issue a few years ago, it's because windows don't have readline, therefore no interactive shell, to use php interactive mode without readline support, you can do this instead:

C:\>php -a 
Interactive mode enabled 

<?php 
echo "Hello, world!"; 
?> 
^Z 
Hello, world!

After entering interactive mode, type using opening (<?php) and closing (?>) php tag, and end with control Z (^Z) which denotes the end of file.

I also recall that I found the solution from php's site user comment: http://www.php.net/manual/en/features.commandline.interactive.php#105729

You need to use JSON.stringify to first serialize your object to JSON, and then specify the contentType so your server understands it's JSON. This should do the trick:

$.ajax({
    url: url,
    type: "POST",
    data: JSON.stringify(data),
    contentType: "application/json",
    complete: callback
});

Note that the JSON object is natively available in browsers that support JavaScript 1.7 / ECMAScript 5 or later. If you need legacy support you can use json2.

Similar to one of the answers above, but try adding .sort_values() to your .groupby() will allow you to change the sort order. If you need to sort on a single column, it would look like this:

df.groupby('group')['id'].count().sort_values(ascending=False)

ascending=False will sort from high to low, the default is to sort from low to high.

*Careful with some of these aggregations. For example .size() and .count() return different values since .size() counts NaNs.

What is the difference between size and count in pandas?

Just put this in the header of your PHP Page and it ill work without API:

header('Access-Control-Allow-Origin: *'); //allow everybody  

or

header('Access-Control-Allow-Origin: http://codesheet.org'); //allow just one domain 

or

$http_origin = $_SERVER['HTTP_ORIGIN'];  //allow multiple domains

$allowed_domains = array(
  'http://codesheet.org',
  'http://stackoverflow.com'
);

if (in_array($http_origin, $allowed_domains))
{  
    header("Access-Control-Allow-Origin: $http_origin");
}

You could use Javascript to achieve this effect. If you use a framework this sort of thing becomes quite simple. Here is an example in jQuery:

$('div#id').click(function (e) {
  // Do whatever you want
});

This solution has the distinct advantage of keeping the logic not in your markup.

Using refs is not best practice because it reads the DOM directly, it's better to use React's state instead. Also, your button doesn't change because the component is not re-rendered and stays in its initial state.

You can use setState together with an onChange event listener to render the component again every time the input field changes:

// Input field listens to change, updates React's state and re-renders the component.
<input onChange={e => this.setState({ value: e.target.value })} value={this.state.value} />

// Button is disabled when input state is empty.
<button disabled={!this.state.value} />

Here's a working example:

class AddItem extends React.Component {_x000D_
  constructor() {_x000D_
    super();_x000D_
    this.state = { value: '' };_x000D_

    this.setState({ value: '' });_x000D_
  }_x000D_
_x000D_
  onChange(e) {_x000D_
    this.setState({ value: e.target.value });_x000D_
  }_x000D_
_x000D_
  render() {_x000D_
    return (_x000D_
      <div className="add-item">_x000D_

This will not work alert(new Date('2010-11-29')); safari have some weird/strict way of processing date format alert(new Date(String('2010-11-29'))); try like this.

(Or)

Using Moment js will solve the issue though, After ios 14 the safari gets even weird

Try this alert(moment(String("2015-12-31 00:00:00")));

This one returns time like youtube videos

    function getYoutubeLikeToDisplay(millisec) {
        var seconds = (millisec / 1000).toFixed(0);
        var minutes = Math.floor(seconds / 60);
        var hours = "";
        if (minutes > 59) {
            hours = Math.floor(minutes / 60);
            hours = (hours >= 10) ? hours : "0" + hours;
            minutes = minutes - (hours * 60);
            minutes = (minutes >= 10) ? minutes : "0" + minutes;
        }

        seconds = Math.floor(seconds % 60);
        seconds = (seconds >= 10) ? seconds : "0" + seconds;
        if (hours != "") {
            return hours + ":" + minutes + ":" + seconds;
        }
        return minutes + ":" + seconds;
    }

Output:

• getYoutubeLikeToDisplay(129900) = "2:10"
• getYoutubeLikeToDisplay(1229900) = "20:30"
• getYoutubeLikeToDisplay(21229900) = "05:53:50"

Using data.frame instead of cbind should be helpful

x <- data.frame(col1=c(10, 20), col2=c("[]", "[]"), col3=c("[[1,2]]","[[1,3]]"))
x
  col1 col2    col3
1   10   [] [[1,2]]
2   20   [] [[1,3]]

sapply(x, class) # looking into x to see the class of each element
     col1      col2      col3 
"numeric"  "factor"  "factor" 

As you can see elements from col1 are numeric as you wish.

data.frame can have variables of different class: numeric, factor and character but matrix doesn't, once you put a character element into a matrix all the other will become into this class no matter what clase they were before.

It happens that /etc/hosts file doesn't support wild card entries.

You'll have to use other services like dnsmasq. To enable it in dnsmasq, just edit dnsmasq.conf and add the following line:

address=/example.com/127.0.0.1

Assuming you’ve literally got two date objects, you can subtract one from the other and query the resulting timedelta object for the number of days:

>>> from datetime import date
>>> a = date(2011,11,24)
>>> b = date(2011,11,17)
>>> a-b
datetime.timedelta(7)
>>> (a-b).days
7

And it works with datetimes too — I think it rounds down to the nearest day:

>>> from datetime import datetime
>>> a = datetime(2011,11,24,0,0,0)
>>> b = datetime(2011,11,17,23,59,59)
>>> a-b
datetime.timedelta(6, 1)
>>> (a-b).days
6

You can use the pskill function in the R "tools" package to interrupt the current process and return to the console. Concretely, I have the following function defined in a startup file that I source at the beginning of each script. You can also copy it directly at the start of your code, however. Then insert halt() at any point in your code to stop script execution on the fly. This function works well on GNU/Linux and judging from the R documentation, it should also work on Windows (but I didn't check).

# halt: interrupts the current R process; a short iddle time prevents R from
# outputting further results before the SIGINT (= Ctrl-C) signal is received 
halt <- function(hint = "Process stopped.\n") {
    writeLines(hint)
    require(tools, quietly = TRUE)
    processId <- Sys.getpid() 
    pskill(processId, SIGINT)
    iddleTime <- 1.00
    Sys.sleep(iddleTime)
}

Its possible at application level. Click on the EJB under the deployment(like Home > >Summary of Deployments >). Click on the Configuration tab and there is "Transaction Timeout:"

C Style casts are easy to miss in a block of code. C++ style casts are not only better practice; they offer a much greater degree of flexibility.

reinterpret_cast allows integral to pointer type conversions, however can be unsafe if misused.

static_cast offers good conversion for numeric types e.g. from as enums to ints or ints to floats or any data types you are confident of type. It does not perform any run time checks.

dynamic_cast on the other hand will perform these checks flagging any ambiguous assignments or conversions. It only works on pointers and references and incurs an overhead.

There are a couple of others but these are the main ones you will come across.

You can use COUNT(DISTINCT ...) :

SELECT COUNT(DISTINCT town) 
FROM user

You can indeed match all those characters, but it's safer to escape the - so that it is clear that it be taken literally.

If you are using a POSIX variant you can opt to use:

([[:alnum:]\-_]+)

But a since you are including the underscore I would simply use:

([\w\-]+)

(works in all variants)

To read a whole line from a file into a string, use std::getline like so:

 std::ifstream file("my_file");
 std::string temp;
 std::getline(file, temp);

You can do this in a loop to until the end of the file like so:

 std::ifstream file("my_file");
 std::string temp;
 while(std::getline(file, temp)) {
      //Do with temp
 }

Yes, a table row can slide up and down, but it's ugly, since it changes the shape of the table and makes everything jump. Instead, put and element in each td... something that makes sense like a p or h2 etc.

For how to implement a table slide toggle...

It's probably simplest to put the click handler on the entire table, .stopPropagation() and check what was clicked.

If a td in a row with a colspan is clicked, close the p in it. If it's not a td in a row with a colspan, then close then toggle the following row's p.

It is essentially to wrap all your written content in an element inside the tds, since you never want to slideUp a td or tr or table shape will change!

Something like:

$(function() {

      // Initially hide toggleable content
    $("td[colspan=3]").find("p").hide();

      // Click handler on entire table
    $("table").click(function(event) {

          // No bubbling up
        event.stopPropagation();

        var $target = $(event.target);

          // Open and close the appropriate thing
        if ( $target.closest("td").attr("colspan") > 1 ) {
            $target.slideUp();
        } else {
            $target.closest("tr").next().find("p").slideToggle();
        }                    
    });
});?

Try it out with this jsFiddle example.

... and try out this jsFiddle showing implementation of a + - - toggle.

The HTML just has to have alternating rows of several tds and then a row with a td of a colspan greater than 1. You can obviously adjust the specifics quite easily.

The HTML would look something like:

<table>
    <tr><td><p>Name</p></td><td><p>Age</p></td><td><p>Info</p></td></tr>
    <tr><td colspan="3"><p>Blah blah blah blah blah blah blah.</p>
    </td></tr>

    <tr><td><p>Name</p></td><td><p>Age</p></td><td><p>Info</p></td></tr>
    <tr><td colspan="3"><p>Blah blah blah blah blah blah blah.</p>
    </td></tr>

    <tr><td><p>Name</p></td><td><p>Age</p></td><td><p>Info</p></td></tr>
    <tr><td colspan="3"><p>Blah blah blah blah blah blah blah.</p>
    </td></tr>    
</table>?

unittest comes with the standard library, but I would recomend you nosetests.

"nose extends unittest to make testing easier."

@Dave an updated snippet from http://www.php.net/manual/en/function.strpos.php#107351

function strposa($haystack, $needles=array(), $offset=0) {
        $chr = array();
        foreach($needles as $needle) {
                $res = strpos($haystack, $needle, $offset);
                if ($res !== false) $chr[$needle] = $res;
        }
        if(empty($chr)) return false;
        return min($chr);
}

How to use:

$string = 'Whis string contains word "cheese" and "tea".';
$array  = array('burger', 'melon', 'cheese', 'milk');

if (strposa($string, $array, 1)) {
    echo 'true';
} else {
    echo 'false';
}

will return true, because of array "cheese".

Update: Improved code with stop when the first of the needles is found:

function strposa($haystack, $needle, $offset=0) {
    if(!is_array($needle)) $needle = array($needle);
    foreach($needle as $query) {
        if(strpos($haystack, $query, $offset) !== false) return true; // stop on first true result
    }
    return false;
}
$string = 'Whis string contains word "cheese" and "tea".';
$array  = array('burger', 'melon', 'cheese', 'milk');
var_dump(strposa($string, $array)); // will return true, since "cheese" has been found

You can do this using cross apply

SELECT c.BalanceDue AS BalanceDue
FROM Invoices
cross apply (select (InvoiceTotal - PaymentTotal - CreditTotal) as BalanceDue) as c
WHERE  c.BalanceDue  > 0;

For text and images you can use text-align:

<div style="text-align: center;">
    I'm centered.
</div>

In IDP Init SSO (Unsolicited Web SSO) the Federation process is initiated by the IDP sending an unsolicited SAML Response to the SP. In SP-Init, the SP generates an AuthnRequest that is sent to the IDP as the first step in the Federation process and the IDP then responds with a SAML Response. IMHO ADFSv2 support for SAML2.0 Web SSO SP-Init is stronger than its IDP-Init support re: integration with 3rd Party Fed products (mostly revolving around support for RelayState) so if you have a choice you'll want to use SP-Init as it'll probably make life easier with ADFSv2.

Here are some simple SSO descriptions from the PingFederate 8.0 Getting Started Guide that you can poke through that may help as well -- https://documentation.pingidentity.com/pingfederate/pf80/index.shtml#gettingStartedGuide/task/idpInitiatedSsoPOST.html

It's better to use script module for that:
http://docs.ansible.com/script_module.html

Easier update:

Use field.selectionStart example in this answer.

Thanks to @commonSenseCode for pointing this out.

Old answer:

Found this solution. Not jquery based but there is no problem to integrate it to jquery:

/*
** Returns the caret (cursor) position of the specified text field (oField).
** Return value range is 0-oField.value.length.
*/
function doGetCaretPosition (oField) {

  // Initialize
  var iCaretPos = 0;

  // IE Support
  if (document.selection) {

    // Set focus on the element
    oField.focus();

    // To get cursor position, get empty selection range
    var oSel = document.selection.createRange();

    // Move selection start to 0 position
    oSel.moveStart('character', -oField.value.length);

    // The caret position is selection length
    iCaretPos = oSel.text.length;
  }

  // Firefox support
  else if (oField.selectionStart || oField.selectionStart == '0')
    iCaretPos = oField.selectionDirection=='backward' ? oField.selectionStart : oField.selectionEnd;

  // Return results
  return iCaretPos;
}

Adding to Jacks solution. I need to Deserialize using the JsonProperty and Serialize while ignoring the JsonProperty (or vice versa). ReflectionHelper and Attribute Helper are just helper classes that get a list of properties or attributes for a property. I can include if anyone actually cares. Using the example below you can serialize the viewmodel and get "Amount" even though the JsonProperty is "RecurringPrice".

    /// <summary>
    /// Ignore the Json Property attribute. This is usefule when you want to serialize or deserialize differently and not 
    /// let the JsonProperty control everything.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    public class IgnoreJsonPropertyResolver<T> : DefaultContractResolver
    {
        private Dictionary<string, string> PropertyMappings { get; set; }

        public IgnoreJsonPropertyResolver()
        {
            this.PropertyMappings = new Dictionary<string, string>();
            var properties = ReflectionHelper<T>.GetGetProperties(false)();
            foreach (var propertyInfo in properties)
            {
                var jsonProperty = AttributeHelper.GetAttribute<JsonPropertyAttribute>(propertyInfo);
                if (jsonProperty != null)
                {
                    PropertyMappings.Add(jsonProperty.PropertyName, propertyInfo.Name);
                }
            }
        }

        protected override string ResolvePropertyName(string propertyName)
        {
            string resolvedName = null;
            var resolved = this.PropertyMappings.TryGetValue(propertyName, out resolvedName);
            return (resolved) ? resolvedName : base.ResolvePropertyName(propertyName);
        }
    }

Usage:

        var settings = new JsonSerializerSettings();
        settings.DateFormatString = "YYYY-MM-DD";
        settings.ContractResolver = new IgnoreJsonPropertyResolver<PlanViewModel>();
        var model = new PlanViewModel() {Amount = 100};
        var strModel = JsonConvert.SerializeObject(model,settings);

Model:

public class PlanViewModel
{

    /// <summary>
    ///     The customer is charged an amount over an interval for the subscription.
    /// </summary>
    [JsonProperty(PropertyName = "RecurringPrice")]
    public double Amount { get; set; }

    /// <summary>
    ///     Indicates the number of intervals between each billing. If interval=2, the customer would be billed every two
    ///     months or years depending on the value for interval_unit.
    /// </summary>
    public int Interval { get; set; } = 1;

    /// <summary>
    ///     Number of free trial days that can be granted when a customer is subscribed to this plan.
    /// </summary>
    public int TrialPeriod { get; set; } = 30;

    /// <summary>
    /// This indicates a one-time fee charged upfront while creating a subscription for this plan.
    /// </summary>
    [JsonProperty(PropertyName = "SetupFee")]
    public double SetupAmount { get; set; } = 0;


    /// <summary>
    /// String representing the type id, usually a lookup value, for the record.
    /// </summary>
    [JsonProperty(PropertyName = "TypeId")]
    public string Type { get; set; }

    /// <summary>
    /// Billing Frequency
    /// </summary>
    [JsonProperty(PropertyName = "BillingFrequency")]
    public string Period { get; set; }


    /// <summary>
    /// String representing the type id, usually a lookup value, for the record.
    /// </summary>
    [JsonProperty(PropertyName = "PlanUseType")]
    public string Purpose { get; set; }
}

The function STR_TO_DATE(COLUMN, '%input_format') can do it, you only have to specify the input format. Example : to convert p052011

SELECT STR_TO_DATE('p052011','p%m%Y') FROM your_table;

The result : 2011-05-00

If you have been committing your code to source control regularly, this may save you the hassle of creating a new Storyboard and possibly introducing more problems...

I was able to solve this by comparing the Git source code of the version that worked against the broken one. The diff showed that the first line should contain the Id of the initial view controller, in my case, initialViewController="Q7U-eo-vxw". I searched through the source code to be sure that the id existed. All I had to do was put it back and everything worked again!

<document type="com.apple.InterfaceBuilder3.CocoaTouch.Storyboard.XIB" version="3.0" toolsVersion="5056" systemVersion="13E28" targetRuntime="iOS.CocoaTouch" propertyAccessControl="none" initialViewController="Q7U-eo-vxw">
    <dependencies>
        <deployment defaultVersion="1296" identifier="iOS"/>
        <plugIn identifier="com.apple.InterfaceBuilder.IBCocoaTouchPlugin" version="3733"/>
    </dependencies>
    <scenes>

Here are some steps that can help you troubleshoot:

1. Right click the failing Storyboard and use Source Control > Commit... to preserve your changes since the last commit.
2. Try right clicking your failing Storyboard and use "Open As > Source Code" to view the XML of the storyboard.
3. In the document element, look for the attribute named "initialViewController". If it is missing, don't worry, we'll fix that. If it is there, double click the id that is assigned to it, command-c to copy it, command-f command-v to search for it deeper in the document. This is the identifier of the controller that should provide the initial view. If it is not defined in the document then that is a problem - you should remove it from the document tag, in my case initialViewController="Q7U-eo-vxw".
4. Go to Xcode menu item called View and choose Version Editor > Show Comparison View
5. This shows your local version on the left and the historical version on the right. Click on the date beneath the historical version to get a list of the commits for this story board. Choose one that you know worked and compare the document element. What is the id of the *initialViewController? Is it different? If so, try editing it back in by hand and running.

You can change it by going File => Settings (Shortcut CTRL+ ALT+ S) , from Left panel Choose Appearance , Now from Right Panel choose theme.

Android Studio 2.1

Preference -> Search for Appearance -> UI options , Click on DropDown Theme

Android 2.2

Android studio -> File -> Settings -> Appearance & Behavior -> Look for UI Options

EDIT :

Import External Themes

You can download custom theme from this website. Choose your theme, download it. To set theme Go to Android studio -> File -> Import Settings -> Choose the .jar file downloaded.

In the nano editor

You need to concatenate your string.

document.getElementById(tabName).style.backgroundImage = 'url(buttons/' + imagePrefix + '.png)';

The way you had it, it's just making 1 long string and not actually interpreting imagePrefix.

I would even suggest creating the string separate:

function ChangeBackgroungImageOfTab(tabName, imagePrefix)
{
    var urlString = 'url(buttons/' + imagePrefix + '.png)';
    document.getElementById(tabName).style.backgroundImage =  urlString;
}

As mentioned by David Thomas below, you can ditch the double quotes in your string. Here is a little article to get a better idea of how strings and quotes/double quotes are related: http://www.quirksmode.org/js/strings.html

So that you don't mess up other permissions already on the file, use the flag +, such as via

sudo chmod -R o+rw /var/www

This is a quick solution in case you want to convert more columns of your pandas.DataFrame from float to integer considering also the case that you can have NaN values.

cols = ['col_1', 'col_2', 'col_3', 'col_4']
for col in cols:
   df[col] = df[col].apply(lambda x: int(x) if x == x else "")

I tried with else x) and else None), but the result is still having the float number, so I used else "".

Check if the cross product of b-a and c-a is0: that means all the points are collinear. If they are, check if c's coordinates are between a's and b's. Use either the x or the y coordinates, as long as a and b are separate on that axis (or they're the same on both).

def is_on(a, b, c):
    "Return true iff point c intersects the line segment from a to b."
    # (or the degenerate case that all 3 points are coincident)
    return (collinear(a, b, c)
            and (within(a.x, c.x, b.x) if a.x != b.x else 
                 within(a.y, c.y, b.y)))

def collinear(a, b, c):
    "Return true iff a, b, and c all lie on the same line."
    return (b.x - a.x) * (c.y - a.y) == (c.x - a.x) * (b.y - a.y)

def within(p, q, r):
    "Return true iff q is between p and r (inclusive)."
    return p <= q <= r or r <= q <= p

This answer used to be a mess of three updates. The worthwhile info from them: Brian Hayes's chapter in Beautiful Code covers the design space for a collinearity-test function -- useful background. Vincent's answer helped to improve this one. And it was Hayes who suggested testing only one of the x or the y coordinates; originally the code had and in place of if a.x != b.x else.

The process manager + task scheduler approach I posted a year ago works well with some one-off service installations. But recently I started to design system in a micro-service fashion, with many small services talking to each other via IPC. So manually configuring each service has become unbearable.

Towards the goal of installing services without manual configuration, I created serman, a command line tool (install with npm i -g serman) to install an executable as a service. All you need to write (and only write once) is a simple service configuration file along with your executable. Run

serman install <path_to_config_file>

will install the service. stdout and stderr are all logged. For more info, take a look at the project website.

A working configuration file is very simple, as demonstrated below. But it also has many useful features such as <env> and <persistent_env> below.

<service>
  <id>hello</id>
  <name>hello</name>
  <description>This service runs the hello application</description>

  <executable>node.exe</executable>

  <!-- 
       {{dir}} will be expanded to the containing directory of your 
       config file, which is normally where your executable locates 
   -->
  <arguments>"{{dir}}\hello.js"</arguments>

  <logmode>rotate</logmode>

  <!-- OPTIONAL FEATURE:
       NODE_ENV=production will be an environment variable 
       available to your application, but not visible outside 
       of your application
   -->
  <env name="NODE_ENV" value="production"/>

  <!-- OPTIONAL FEATURE:
       FOO_SERVICE_PORT=8989 will be persisted as an environment
       variable machine-wide.
   -->
  <persistent_env name="FOO_SERVICE_PORT" value="8989" />
</service>

Use Convert.ToString (value, 2)

so in your case

string binValue = Convert.ToString (3, 2);

Spring Data JPA 1.11 now supports the exists projection in repository query derivation.

See documentation here.

In your case the following will work:

public interface MyEntityRepository extends CrudRepository<MyEntity, String> {  
    boolean existsByFoo(String foo);
}

For those looking for a solution from an Angular perspective, this worked for me:

$http.post(
  'url',
  {},
  {responseType: 'arraybuffer'}
).then(function (response) {
  var headers = response.headers();
  var blob = new Blob([response.data],{type:headers['content-type']});
  var link = document.createElement('a');
  link.href = window.URL.createObjectURL(blob);
  link.download = "Filename";
  link.click();
});

From the project directory type the following:

Deleting all .pyc files

find . -path "*/*.pyc" -delete

Deleting all .pyo files:

find . -path "*/*.pyo" -delete

Finally, to delete all '__pycache__', type:

find . -path "*/__pycache__" -type d -exec rm -r {} ';'

If you encounter permission denied error, add sudo at the begining of all the above command.

Ok, I tried something like this:

body (normal)

#MainDiv { 
  /* where all the content goes */
  display: table;
  overflow-y: auto;
}

It's not the exact way to write it, but if you make the main div display as a table, it expands and then I implemented scroll bars.

To be able to use a lib project you need to include it in your application's settings.gradle add:

include '..:ExpandableButtonMenu:library'

and then in your build.gradle add:

compile project(':..:ExpandableButtonMenu:library') 

place ExpandableButtonMenu project along side your own (same folder)

see this How to build an android library with Android Studio and gradle? for more details.

One solution that may work (it works for me) is to apply negative margin at input (textbox)... or fixed width for ie7 or to drop ie7 support. This results to pixel perfect width.. For me its 7 so i added 3 and 4 but it is still pixel perfect..

I had the same problem and i hated to have extra divs for border etc!

So here is my solution which seems to work!

You should use a ie7 only stylesheet to avoid the starhacks.

input.text{
    background-color: #fbfbfb;
    border : solid #eee 1px;
    width: 100%;
    -box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
    height: 32px;

    *line-height:32px;
    *margin-left:-3px;
    *margin-right:-4px;
    display: inline;   
    padding: 0px 0 0 5px;

To show vertical scroll bar in your div you need to add

height: 100px;   
overflow-y : scroll;

or

height: 100px; 
overflow-y : auto;

I don't know anything about jquery so can't help you with that, but as far as Javascript is concerned you have an array of objects, so what you will only be able to access the names & values through each array element. E.g arr[0].name will give you 'k1', arr[1].value will give you 'hi'.

Maybe you want to do something like:

var obj = {};

obj.k1 = "abc";
obj.k2 = "hi";
obj.k3 = "oa";

alert ("obj.k2:" + obj.k2);

Here are TypeScript equivalents of some common .NET delegates:

interface Action<T>
{
    (item: T): void;
}

interface Func<T,TResult>
{
    (item: T): TResult;
}

As Thrasgod correctly showed in his answer, the best way is to use the paintComponent, but also if the case is to have a semi transparent JPanel (or any other component, really) and have something not transparent inside. You have to also override the paintChildren method and set the alfa value to 1. In my case I extended the JPanel like that:

public class TransparentJPanel extends JPanel {

private float panelAlfa;
private float childrenAlfa;

public TransparentJPanel(float panelAlfa, float childrenAlfa) {
    this.panelAlfa = panelAlfa;
    this.childrenAlfa = childrenAlfa;
}

@Override
public void paintComponent(Graphics g) {
    Graphics2D g2d = (Graphics2D) g;
    g2d.setColor(getBackground());
    g2d.setRenderingHint(
            RenderingHints.KEY_ANTIALIASING,
            RenderingHints.VALUE_ANTIALIAS_ON);
    g2d.setComposite(AlphaComposite.getInstance(
            AlphaComposite.SRC_OVER, panelAlfa));
    super.paintComponent(g2d);

}

@Override
protected void paintChildren(Graphics g) {
    Graphics2D g2d = (Graphics2D) g;
    g2d.setColor(getBackground());
    g2d.setRenderingHint(
            RenderingHints.KEY_ANTIALIASING,
            RenderingHints.VALUE_ANTIALIAS_ON);
    g2d.setComposite(AlphaComposite.getInstance(
            AlphaComposite.SRC_ATOP, childrenAlfa));
  
    super.paintChildren(g); 
}
 //getter and setter
}

And in my project I only need to instantiate Jpanel jp = new TransparentJPanel(0.3f, 1.0f);, if I want only the Jpanel transparent. You could, also, mess with the JPanel shape using g2d.fillRoundRect and g2d.drawRoundRect, but it's not in the scope of this question.

I had to use the following command to start the build:

docker build .

Something to be aware of, the $_SESSION variables are still set in the same page after calling session_destroy() where as this is not the case when using unset($_SESSION) or $_SESSION = array(). Also, unset($_SESSION) blows away the $_SESSION superglobal so only do this when you're destroying a session.

With all that said, it's best to do like the PHP docs has it in the first example for session_destroy().

You can also toggle this for select lines in your script by wrapping them in set -x and set +x, for example,

#!/bin/bash
...
if [[ ! -e $OUT_FILE ]];
then
   echo "grabbing $URL"
   set -x
   curl --fail --noproxy $SERV -s -S $URL -o $OUT_FILE
   set +x
fi

Try using ZoomView for zooming any other view.

The typical answer is this:

1. In Excel, File/Save As, select CSV, save your current sheet.

2. transfer to a holding directory on the Pg server the postgres user can access

3. in PostgreSQL:

   COPY mytable FROM '/path/to/csv/file' WITH CSV HEADER; -- must be superuser
   

But there are other ways to do this too. PostgreSQL is an amazingly programmable database. These include:

1. Write a module in pl/javaU, pl/perlU, or other untrusted language to access file, parse it, and manage the structure.

2. Use CSV and the fdw_file to access it as a pseudo-table

3. Use DBILink and DBD::Excel

4. Write your own foreign data wrapper for reading Excel files.

The possibilities are literally endless....

You just need to wrap object in ()

var arr = [{_x000D_
  id: 1,_x000D_
  name: 'bill'_x000D_
}, {_x000D_
  id: 2,_x000D_
  name: 'ted'_x000D_
}]_x000D_

You haven't put the shared library in a location where the loader can find it. look inside the /usr/local/opencv and /usr/local/opencv2 folders and see if either of them contains any shared libraries (files beginning in lib and usually ending in .so). when you find them, create a file called /etc/ld.so.conf.d/opencv.conf and write to it the paths to the folders where the libraries are stored, one per line.

for example, if the libraries were stored under /usr/local/opencv/libopencv_core.so.2.4 then I would write this to my opencv.conf file:

/usr/local/opencv/

Then run

sudo ldconfig -v

If you can't find the libraries, try running

sudo updatedb && locate libopencv_core.so.2.4

in a shell. You don't need to run updatedb if you've rebooted since compiling OpenCV.

There seems to be a lot of misinformation about how to use this event going around (even in upvoted answers on this page).

The onbeforeunload event API is supplied by the browser for a specific purpose: The only thing you can do that's worth doing in this method is to return a string which the browser will then prompt to the user to indicate to them that action should be taken before they navigate away from the page. You CANNOT prevent them from navigating away from a page (imagine what a nightmare that would be for the end user).

Because browsers use a confirm prompt to show the user the string you returned from your event listener, you can't do anything else in the method either (like perform an ajax request).

In an application I wrote, I want to prompt the user to let them know they have unsaved changes before they leave the page. The browser prompts them with the message and, after that, it's out of my hands, the user can choose to stay or leave, but you no longer have control of the application at that point.

An example of how I use it (pseudo code):

onbeforeunload = function() {

  if(Application.hasUnsavedChanges()) {
    return 'You have unsaved changes. Please save them before leaving this page';
  }


};

If (and only if) the application has unsaved changes, then the browser prompts the user to either ignore my message (and leave the page anyway) or to not leave the page. If they choose to leave the page anyway, too bad, there's nothing you can do (nor should be able to do) about it.

For me the issue was when I tried to access HTTPContext in the Controller's constructor while HTTPContext is not ready yet. When moved inside Index method it worked:

var uri = new Uri(Request.Url.AbsoluteUri);
url = uri.Scheme + "://" + uri.Host + "/";enter code here

They are the same (as is the third form, ^=).

Note, though, that they are still considered different from the point of view of the parser, that is a stored outline defined for a != won't match <> or ^=.

This is unlike PostgreSQL where the parser treats != and <> yet on parsing stage, so you cannot overload != and <> to be different operators.

All you wanted (at the time the question was originally asked) was a hint. Here's a hint: In Python, you can use dictionaries.

You can also get content such as the first pagagraph via DBPedia which takes Wikipedia content and creates structured information from it (RDF) and makes this available via an API. The DBPedia API is a SPARQL one (RDF-based) but it outputs JSON and it is pretty easy to wrap.

As an example here's a super simple JS library named WikipediaJS that can extract structured content including a summary first paragraph: http://okfnlabs.org/wikipediajs/

You can read more about it in this blog post: http://okfnlabs.org/blog/2012/09/10/wikipediajs-a-javascript-library-for-accessing-wikipedia-article-information.html

The JS library code can be found here: https://github.com/okfn/wikipediajs/blob/master/wikipedia.js

Given this piece of HTML code:

<a href='https://facebook.com/'>Facebook</a>
<a href='https://google.ca/'>Google</a>
<input type='text' placeholder='an input box'>

We can use this JavaScript:

function checkTabPress(e) {
    'use strict';
    var ele = document.activeElement;

    if (e.keyCode === 9 && ele.nodeName.toLowerCase() === 'a') {
        console.log(ele.href);
    }
}

document.addEventListener('keyup', function (e) {
    checkTabPress(e);
}, false);

I have bound an event listener to the document element for the keyUp event, which triggers a function to check if the Tab key was pressed (or technically, released).

The function checks the currently focused element and whether the NodeName is a. If so, it enters the if block and, in my case, writes the value of the href property to the JavaScript console.

Here's a jsFiddle

This link provides a lot of resources for VB6 Decompiling, but it seems like it will depend greatly on what you DO have (do you still have the pre-link Object code [EDIT: er... p-code I mean], or just the EXE?) Either way, it looks like there's something, take a look in there.

Judge by yesterday's weather. How long did it take last time? Are you trending longer or shorter? Each shop is different.

Most agile shops need a lot less time, have drastically fewer defects, and quicker time to resolve them because of TDD. Even so, most agile shops have some measurable time spent with testing/QC.

If this is the first test run for this application, then the answer is "lets see" followed by an attempt. It depends on how quick you can get questions answered, - how testable it is, - how many features/functions - how many defects are discovered, - how quickly issues are resolved, - how many times the code cycles through testing, and - how many times testing is blocked by bugs. There is no way to tell. You could call it 50% or 175% or more, and not be wrong. Why not make a rough guess and multiply by Pi? It won't be much worse than any other answer you can make up.

You should (must) know how long it takes now and whether it's getting faster or slower, and whether the coverage is increasing or decreasing. With those three bits of information, you should be able to guess quite well.

If it doesn't show up in your package manager (i.e. apt-cache search texinfo) and even apt-file search bin/makeinfo is no help, you may have to enable non-free/restricted packages for your package manager.

For ubuntu, sudo $EDITOR /etc/apt/sources.list and add restricted.

deb http://archive.ubuntu.com/ubuntu bionic main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu bionic-security main
deb http://archive.ubuntu.com/ubuntu bionic-updates main

For debian, sudo $EDITOR /etc/apt/sources.list and add non-free. You can even have preferences on package level if you don't want to clutter the package db with non-free stuff.

After a sudo apt-get udpate you should find the required package.

In my case to get my debug build - I have to turn off Instant Run option :

File ? Settings ? Build, Execution, Deployment ? Instant Run and uncheck Enable Instant Run.

Then after run project - I found my build into Application\app\build\outputs\appDebug\apk directory

Are you posting from a different source (so different port, or hostname)? If so, this very very recent topic I just answered might be helpful.

• Odd jQuery problem - Ajax request to a C program not quite working

The problem was the XHR Cross Domain Policy, and a useful tip on how to get around it by using a technique called JSONP. The big downside is that JSONP does not support POST requests.

I know in the original post there is no mention of JavaScript, however JSON is usually used for JavaScript so that's why I jumped to that conclusion

The error you are receiving is due to how you define jet. You are creating the base class Colormap with the name 'jet', but this is very different from getting the default definition of the 'jet' colormap. This base class should never be created directly, and only the subclasses should be instantiated.

What you've found with your example is a buggy behavior in Matplotlib. There should be a clearer error message generated when this code is run.

This is an updated version of your example:

import matplotlib.pyplot as plt
import matplotlib.colors as colors
import matplotlib.cm as cmx
import numpy as np

# define some random data that emulates your indeded code:
NCURVES = 10
np.random.seed(101)
curves = [np.random.random(20) for i in range(NCURVES)]
values = range(NCURVES)

fig = plt.figure()
ax = fig.add_subplot(111)
# replace the next line 
#jet = colors.Colormap('jet')
# with
jet = cm = plt.get_cmap('jet') 
cNorm  = colors.Normalize(vmin=0, vmax=values[-1])
scalarMap = cmx.ScalarMappable(norm=cNorm, cmap=jet)
print scalarMap.get_clim()

lines = []
for idx in range(len(curves)):
    line = curves[idx]
    colorVal = scalarMap.to_rgba(values[idx])
    colorText = (
        'color: (%4.2f,%4.2f,%4.2f)'%(colorVal[0],colorVal[1],colorVal[2])
        )
    retLine, = ax.plot(line,
                       color=colorVal,
                       label=colorText)
    lines.append(retLine)
#added this to get the legend to work
handles,labels = ax.get_legend_handles_labels()
ax.legend(handles, labels, loc='upper right')
ax.grid()
plt.show()

Resulting in:

Using a ScalarMappable is an improvement over the approach presented in my related answer: creating over 20 unique legend colors using matplotlib
