DTD is pretty much deprecated because it is limited in its usefulness as a schema language, doesn't support namespace, and does not support data type. In addition, DTD's syntax is quite complicated, making it difficult to understand and maintain..

Call SYS_CONTEXT to get the current schema. From Ask Tom "How to get current schema:

select sys_context( 'userenv', 'current_schema' ) from dual;

x or "default"

works best — i can even use a function call inline, without executing it twice or using extra variable:

self.lineEdit_path.setText( self.getDir(basepath) or basepath )

I use it when opening Qt's dialog.getExistingDirectory() and canceling, which returns empty string.

data.rename(columns={'gdp':'log(gdp)'}, inplace=True)

The rename show that it accepts a dict as a param for columns so you just pass a dict with a single entry.

The problem comes from your Java application (or a library you are using).

First, you should read the entire outputs (Google for StreamGobbler), and pronto!

Javadoc says:

The parent process uses these streams to feed input to and get output from the subprocess. Because some native platforms only provide limited buffer size for standard input and output streams, failure to promptly write the input stream or read the output stream of the subprocess may cause the subprocess to block, and even deadlock.

Secondly, waitFor() your process to terminate. You then should close the input, output and error streams.

Finally destroy() your Process.

Try This

if (($val >= 1 && $val <= 10) || ($val >= 20 && $val <= 40))

This will return the value between 1 to 10 & 20 to 40.

I have already update my node to Version 5.0.0 And I work work with this:

function toArrayBuffer(buffer){
    var array = [];
    var json = buffer.toJSON();
    var list = json.data

    for(var key in list){
        array.push(fixcode(list[key].toString(16)))
    }

    function fixcode(key){
        if(key.length==1){
            return '0'+key.toUpperCase()
        }else{
            return key.toUpperCase()
        }
    }

    return array
}

I use it to check my vhd disk image.

Enclose <img> in <a> tag.

<a href="http://www.google.com.pk"><img src="smiley.gif"></a>

it will open link on same tab, and if you want to open link on new tab then use target="_blank"

<a href="http://www.google.com.pk" target="_blank"><img src="smiley.gif"></a>

I think that the URI class is the one that you are looking for.

What if the incoming changes are the ones you want? I'm unable to run svn resolve --accept theirs-full

Please check the proposed solution from here that uses a semaphore to determine if an existing instance is already running, works for a WPF application and can pass arguments from second instance to the first already running instance by using a TcpListener and a TcpClient:

It works also for .NET Core, not only for .NET Framework.

If you use a TFS online(Cloud version) and you want to transform the App.Config in a project, you can do the following without installing any extra tools. From VS => Unload the project => Edit project file => Go to the bottom of the file and add the following:

<UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v$(VisualStudioVersion)\Web\Microsoft.Web.Publishing.Tasks.dll" />
<Target Name="AfterBuild" Condition="Exists('App.$(Configuration).config')">
<TransformXml Source="App.config" Transform="App.$(Configuration).config" Destination="$(OutDir)\$(AssemblyName).dll.config" />

AssemblyFile and Destination works for local use and TFS online(Cloud) server.

This is a step-by-step procedure to get pkg-config working on Windows, based on my experience, using the info from Oliver Zendel's comment.

I assume here that MinGW was installed to C:\MinGW. There were multiple versions of the packages available, and in each case I just downloaded the latest version.

1. go to http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/
2. download the file pkg-config_0.26-1_win32.zip
3. extract the file bin/pkg-config.exe to C:\MinGW\bin
4. download the file gettext-runtime_0.18.1.1-2_win32.zip
5. extract the file bin/intl.dll to C:\MinGW\bin
6. go to http://ftp.gnome.org/pub/gnome/binaries/win32/glib/2.28
7. download the file glib_2.28.8-1_win32.zip
8. extract the file bin/libglib-2.0-0.dll to C:\MinGW\bin

Now CMake will be able to use pkg-config if it is configured to use MinGW.

This is really easy using jQuery.

For instance:

$(".left").mouseover(function(){$(".left1").show()});
$(".left").mouseout(function(){$(".left1").hide()});

I've update your fiddle: http://jsfiddle.net/TqDe9/2/

Instead of os.path.isfile, suggested by others, I suggest using os.path.exists, which checks for anything with that name, not just whether it is a regular file.

Thus:

if not os.path.exists(filename):
    file(filename, 'w').close()

Alternatively:

file(filename, 'w+').close()

The latter will create the file if it exists, but not otherwise. It will, however, fail if the file exists, but you don't have permission to write to it. That's why I prefer the first solution.

For my mac Big Sur, with gist from answers above, following steps work for me.

$ ssh-keygen -q -t rsa -N 'password' -f ~/.ssh/id_rsa
$ ssh-add ~/.ssh/id_rsa

And added ssh public key to git hub by following instruction;

https://docs.github.com/en/github/authenticating-to-github/adding-a-new-ssh-key-to-your-github-account

If all gone well, you should be able to get the following result;

$ ssh -T [email protected]
Hi user_name! You've successfully authenticated,...

Is something along these lines what you are looking for?

x1 = function(x){
  mu = mean(x)
  l1 = list(s1=table(x),std=sd(x))
  return(list(l1,mu))
}

library(Ecdat)
data(Fair)
x1(Fair$age)

Ideally your .gitignore should prevent the untracked ( and ignored )files from being shown in status, added using git add etc. So I would ask you to correct your .gitignore

You can do git add -u so that it will stage the modified and deleted files.

You can also do git commit -a to commit only the modified and deleted files.

Note that if you have Git of version before 2.0 and used git add ., then you would need to use git add -u . (See "Difference of “git add -A” and “git add .”").

The easiest is to put overflow:hidden on the parent div and don't specify a height:

#parent { overflow: hidden }

Another way is to also float the parent div:

#parent { float: left; width: 100% }

Another way uses a clear element:

<div class="parent">
   <img class="floated_child" src="..." />
   <span class="clear"></span>
</div>

CSS

span.clear { clear: left; display: block; }

A one-line version of this excellent answer to plot the line of best fit is:

plt.plot(np.unique(x), np.poly1d(np.polyfit(x, y, 1))(np.unique(x)))

Using np.unique(x) instead of x handles the case where x isn't sorted or has duplicate values.

The call to poly1d is an alternative to writing out m*x + b like in this other excellent answer.

psql -U postgres

Worked fine for me in case of db name: postgres & username: postgres. So you do not need to write sudo.

And in the case other db, you may try

psql -U yourdb postgres

As it is given in Postgres help:

psql [OPTION]... [DBNAME [USERNAME]]

function function_one() {_x000D_
    function_two(); // considering the next alert, I figured you wanted to call function_two first_x000D_
    alert("The function called 'function_one' has been called.");_x000D_
}_x000D_
_x000D_
function function_two() {_x000D_
    alert("The function called 'function_two' has been called.");_x000D_
}_x000D_
_x000D_
function_one();

A little bit more context: this works in JavaScript because of a language feature called "variable hoisting" - basically, think of it like variable/function declarations are put at the top of the scope (more info).

Like @g-eorge mention, you can make it like this:

module.config(['$routeProvider', function($routeProvider) {
$routeProvider.
  when('/users/:userId?', {templateUrl: 'template.tpl.html', controller: myCtrl})
}]);

You can also make as much as u need optional parameters.

here I've done some O(n) solution for objects. Not few-lines solution, but...

    var underlyingObject: T
    var distinctAttribute: String

            let winner = resolution(old.underlyingObject, wrapper.underlyingObject)
            added.insert(DistinctWrapper(underlyingObject: winner, distinctAttribute: distinctAttribute(winner)))
        } else {
            added.insert(wrapper)
        }
    }
    return Array(added).map( { return $0.underlyingObject } )
}

    return lhs.hashValue == rhs.hashValue
}

In Bootstrap 4 (beta), use align-middle. Refer to Bootstrap 4 Documentation on Vertical alignment:

Change the alignment of elements with the vertical-alignment utilities. Please note that vertical-align only affects inline, inline-block, inline-table, and table cell elements.

Choose from .align-baseline, .align-top, .align-middle, .align-bottom, .align-text-bottom, and .align-text-top as needed.

As far as I can tell, whether you throw an exception, or you return Request.CreateErrorResponse, the result is the same. If you look at the source code for System.Web.Http.dll, you will see as much. Take a look at this general summary, and a very similar solution that I have made: Web Api, HttpError, and the behavior of exceptions

You should not create a new Random instance in a loop. Try something like:

var rnd = new Random();
for(int i = 0; i < 100; ++i) 
   Console.WriteLine(rnd.Next(1, 100));

The sequence of random numbers generated by a single Random instance is supposed to be uniformly distributed. By creating a new Random instance for every random number in quick successions, you are likely to seed them with identical values and have them generate identical random numbers. Of course, in this case, the generated sequence will be far from uniform distribution.

For the sake of completeness, if you really need to reseed a Random, you'll create a new instance of Random with the new seed:

rnd = new Random(newSeed);

For some reason it didn't work for me. So I had to use something else.

select "option_name_here", :from => "organizationSelect"

worked for me.

Don't know if this is faster but I'm using

float fp = ip % 1.0f;

There are three ways of doing this.

let say you have a list of integers

my_list = [100,200,300]

1. "-".join(str(n) for n in my_list)
2. "-".join([str(n) for n in my_list])
3. "-".join(map(str, my_list))

However as stated in the example of timeit on python website at https://docs.python.org/2/library/timeit.html using a map is faster. So I would recommend you using "-".join(map(str, my_list))

Readify used to run their TFSNow hosted TFS service, but I don't think it's going any longer. The only others I've heard of, apart from CodePlex, aren't free:

• Phase2
• TeamDevCentral
• Saas Made Easy

The syntax to store the command output into a variable is var=$(command).

So you can directly do:

result=$(ls -l | grep -c "rahul.*patle")

And the variable $result will contain the number of matches.

This issue could be because of wrong entity framework reference or sometimes the Class name not matching the entity name in database. Make sure the Table name matches with class name.

Using the following code in Activity.

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int height = metrics.heightPixels;
int wwidth = metrics.widthPixels;

Just wanted to add an option that I started using because I use Azure SQL and the multiple table thing was way too cumbersome for me. I added an insert/update/delete trigger on my table and then converted the before/after change to json using the "FOR JSON AUTO" feature.

 SET @beforeJson = (SELECT * FROM DELETED FOR JSON AUTO)
SET @afterJson = (SELECT * FROM INSERTED FOR JSON AUTO)

That returns a JSON representation fo the record before/after the change. I then store those values in a history table with a timestamp of when the change occurred (I also store the ID for current record of concern). Using the serialization process, I can control how data is backfilled in the case of changes to schema.

I learned about this from this link here

I needed C++ implementation working on std::string. None of answers satisfied my needs, I needed simple two-function solution for encoding and decoding, but I was too lazy to write my own code, so I found this:

As per https://android.stackexchange.com/a/78183/239063 you can run a one line command in Linux to add in an appropriate tar header to extract it.

( printf "\x1f\x8b\x08\x00\x00\x00\x00\x00" ; tail -c +25 backup.ab ) | tar xfvz -

Replace backup.ab with the path to your file.

I made the mistake of incorrectly naming a backup file in the /etc/httpd/conf.d directory. In the README it states that it alphabetically goes through all .conf files.

I had created ssl-<date>.conf (meant to be a backup) and it was loading before ssl.conf. It was binding the :443 port based on the ssl-<date>.conf and failing on the ssl.conf.

Once I renamed the backup file to ssl.conf.<date>, the service started without issue.

As a note, the server I'm on is running RHEL 6

In my case, I forgot to set database env for deployment. you can set env by this command (I'm using mLab for MongoDB server)

heroku config:set MONGO_URI='mongodb://address'

The answer is no. When the parser reaches the first return statement, it will direct control back to the calling function - your second return statement will never be executed.

When you encounter exceptions like this, the most useful information is generally at the bottom of the stacktrace:

Caused by: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
  at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
  ...
  at org.apache.tomcat.jdbc.pool.PooledConnection.connectUsingDriver(PooledConnection.java:246)

The problem is that Tomcat can't find com.mysql.jdbc.Driver. This is usually caused by the JAR containing the MySQL driver not being where Tomcat expects to find it (namely in the webapps/<yourwebapp>/WEB-INF/lib directory).

Probably you need an array?

var Game = {

    status: [
        ["val", "val","val"],
        ["val", "val", "val"]
    ]
}

alert(Game.status[0][0]);

1. If you have android studio installed within your system, then copy the templates folder from C:\Program Files\Android\Android Studio\plugins\android\lib\templates
2. Paste it in the folder C:\Users\<user-name>\AppData\Local\Android\sdk\tools
3. Run the command: ionic build android

All necessary jar files will be downloaded and apk file for the application will be generated.

Note: Set environment variables to C:\Users\<user-name>\AppData\Local\Android\sdk\tools. Also set user-name to your current username.

You need remove path.moveTo after first initial.

Path path = new Path();
path.moveTo(point1_returned.x, point1_returned.y);
path.lineTo(point2_returned.x, point2_returned.y);
path.lineTo(point3_returned.x, point3_returned.y);

path.close();

You can use anycache to do the job for you. It considers all the details:

• It uses dill as backend, which extends the python pickle module to handle lambda and all the nice python features.
• It stores different objects to different files and reloads them properly.
• Limits cache size
• Allows cache clearing
• Allows sharing of objects between multiple runs
• Allows respect of input files which influence the result

Assuming you have a function myfunc which creates the instance:

from anycache import anycache

class Company(object):
    def __init__(self, name, value):
        self.name = name
        self.value = value

@anycache(cachedir='/path/to/your/cache')    
def myfunc(name, value)
    return Company(name, value)

Anycache calls myfunc at the first time and pickles the result to a file in cachedir using an unique identifier (depending on the function name and its arguments) as filename. On any consecutive run, the pickled object is loaded. If the cachedir is preserved between python runs, the pickled object is taken from the previous python run.

For any further details see the documentation

You have to use a dictionnary/array. For example :

 to_19= ['zero','one','two','three','four','five','six','seven','eight','nine'..'nineteen']
 tens = ['twenty'...'ninety']

And you could generate the string of a number by doing, for example :

 if len(str(number)) == 2 and  number > 20:
       word_number = tens[str(number)[0]]+' '+units[str(number)[0]]

You have to check if the last figure is not a zero and so on.. classic value checking.

It reminds a project euler challenge (problem 17).. you should try to find some solutions about it

Hope it helps

If you know the child element you're interested in is the first:

 $('.second').children().first();

Or to find by index:

 var index = 0
 $('.second').children().eq(index);

try like below it will work...

<html>
<head>
<script>
function displayResult(element)
{
document.getElementById(element).value = 'hi';
}
</script>
</head>
<body>

<textarea id="myTextarea" cols="20">
BYE
</textarea>
<br>

<button type="button" onclick="displayResult('myTextarea')">Change</button>

</body>
</html>

Please try like this : git clone --single-branch --branch <branchname> <url>

replace <branchname> with your branch and <url> with your url.

url will be like http://[email protected]:portno/yourrepo.git.

2. (& pause) Pause the CURRENT cmd instance.

How to resolve it? well,using the correct syntax, enclosing the argument for the new CMD instance:

cmd.exe /k ""<SomePath>\<My Batch File>.bat" & pause"

You need to use delimiters with regexes in PHP. You can use the often used /, but PHP lets you use any matching characters, so @ and # are popular.

Further Reading.

If you are interpolating variables inside your regex, be sure to pass the delimiter you chose as the second argument to preg_quote().

Well, first of all that code doesn't compile.

After removing the extra semicolon after i++, it compiles and runs fine for me.

I have never come across a situation where one needs to call a destructor manually. I seem to remember even Stroustrup claims it is bad practice.

Yes there is.

But OCR is very vast. I know an Android application that has an OCR feature, but that might not be the kind of OCR you are looking after.

This open-source application is called Aedict, and it does OCR on handwritten Japanese characters. It is not that slow.

If it is not what you are looking for, please precise which kind of characters, and which data input (image or X-Y touch history).

Using <scope>system</scope> is a terrible idea for reasons explained by others, installing the file manually to your local repository makes the build unreproducible, and using <url>file://${project.basedir}/repo</url> is not a good idea either because (1) that may not be a well-formed file URL (e.g. if the project is checked out in a directory with unusual characters), (2) the result is unusable if this project’s POM is used as a dependency of someone else’s project.

Assuming you are unwilling to upload the artifact to a public repository, Simeon’s suggestion of a helper module does the job. But there is an easier way now…

The Recommendation

Use non-maven-jar-maven-plugin. Does exactly what you were asking for, with none of the drawbacks of the other approaches.

It is defined as:

typedef unsigned long       DWORD;

However, according to the MSDN:

On 32-bit platforms, long is synonymous with int.

Therefore, DWORD is 32bit on a 32bit operating system. There is a separate define for a 64bit DWORD:

typdef unsigned _int64 DWORD64;

Hope that helps.

An easy way to include a separately installed JDK in the list given by /usr/libexec/java_home -V is to symlink the directory as follows:

sudo ln -s path/to/jdk /Library/Java/JavaVirtualMachines/jdk-[some-identifier].jdk

For example, to register the JDK included with Android Studio (1.8.0_152 at the time of writing), use:

sudo ln -s /Applications/Android\ Studio.app/Contents/jre/jdk /Library/Java/JavaVirtualMachines/jdk-android-studio.jdk

Now java_home will list the JDK under Matching Java Virtual Machines and you can select it as described above.

This function will do as JohnFx suggested and allow for varied lengths on the arrays

Function mergeArrays(ByVal arr1 As Variant, ByVal arr2 As Variant) As Variant
    Dim holdarr As Variant
    Dim ub1 As Long
    Dim ub2 As Long
    Dim bi As Long
    Dim i As Long
    Dim newind As Long

        ub1 = UBound(arr1) + 1
        ub2 = UBound(arr2) + 1

        bi = IIf(ub1 >= ub2, ub1, ub2)

        ReDim holdarr(ub1 + ub2 - 1)

        For i = 0 To bi
            If i < ub1 Then
                holdarr(newind) = arr1(i)
                newind = newind + 1
            End If

            If i < ub2 Then
                holdarr(newind) = arr2(i)
                newind = newind + 1
            End If
        Next i

        mergeArrays = holdarr
End Function

You may use Map.entrySet() method:

for (Map.Entry entry : objectSet.entrySet())
{
    System.out.println("key: " + entry.getKey() + "; value: " + entry.getValue());
}

In Node.js, "high resolution time" is made available via process.hrtime. It returns a array with first element the time in seconds, and second element the remaining nanoseconds.

To get current time in microseconds, do the following:

var hrTime = process.hrtime()
console.log(hrTime[0] * 1000000 + hrTime[1] / 1000)

(Thanks to itaifrenkel for pointing out an error in the conversion above.)

In modern browsers, time with microsecond precision is available as performance.now. See https://developer.mozilla.org/en-US/docs/Web/API/Performance/now for documentation.

I've made an implementation of this function for Node.js, based on process.hrtime, which is relatively difficult to use if your solely want to compute time differential between two points in a program. See http://npmjs.org/package/performance-now . Per the spec, this function reports time in milliseconds, but it's a float with sub-millisecond precision.

In Version 2.0 of this module, the reported milliseconds are relative to when the node process was started (Date.now() - (process.uptime() * 1000)). You need to add that to the result if you want a timestamp similar to Date.now(). Also note that you should bever recompute Date.now() - (process.uptime() * 1000). Both Date.now and process.uptime are highly unreliable for precise measurements.

To get current time in microseconds, you can use something like this.

var loadTimeInMS = Date.now()
var performanceNow = require("performance-now")
console.log((loadTimeInMS + performanceNow()) * 1000)

You may try like this:

import java.applet.Applet;
import java.awt.*;

public class Rect1 extends Applet {

  public void paint (Graphics g) {
    g.drawRect (x, y, width, height);    //can use either of the two//
    g.fillRect (x, y, width, height);
    g.setColor(color);
  }

}

where x is x co-ordinate y is y cordinate color=the color you want to use eg Color.blue

if you want to use rectangle object you could do it like this:

import java.applet.Applet;
import java.awt.*;

public class Rect1 extends Applet {

  public void paint (Graphics g) {    
    Rectangle r = new Rectangle(arg,arg1,arg2,arg3);
    g.fillRect(r.getX(), r.getY(), r.getWidth(), r.getHeight());
    g.setColor(color);
  }
}       

You can add this script for showing your own message.

 <script>
     input = document.getElementById("topicName");

            input.addEventListener('invalid', function (e) {
                if(input.validity.valueMissing)
                {
                    e.target.setCustomValidity("Please enter topic name");
                }
//To Remove the sticky error message at end write


            input.addEventListener('input', function (e) {
                e.target.setCustomValidity('');
            });
        });

</script>

For other validation like pattern mismatch you can add addtional if else condition

like

else if (input.validity.patternMismatch) 
{
  e.target.setCustomValidity("Your Message");
}

there are other validity conditions like rangeOverflow,rangeUnderflow,stepMismatch,typeMismatch,valid

This works for mi fine on mac

kill -9 `ps -ef | awk '/nohup/{ print \$2 }'`

Of course it matters........ !

Let's walk this through with examples.In our example we will declare function in two different ways.

We will be using both function declaration and Function Constructor. We will se how typeof and instanceof behaves in those two different scenarios.

Create function using function declaration :

function MyFunc(){  }

typeof Myfunc == 'function' // true

MyFunc instanceof Function // false

Possible explanation for such different result is, as we made a function declaration , typeof can understand that it is a function.Because typeof checks whether or not the expression on which typeof is operation on, in our case MyFunc implemented Call Method or not. If it implements Call method it is a function.Otherwise not .For clarification check ecmascript specification for typeof.

Create function using function constructor :

var MyFunc2 = new Function('a','b','return a+b') // A function constructor is used 

typeof MyFunc2 == 'function' // true

MyFunc2 instanceof Function // true

Here typeof asserts that MyFunc2 is a function as well as the instanceof operator.We already know typeof check if MyFunc2 implemented Call method or not.As MyFunc2 is a function and it implements call method,that's how typeof knows that it's a function.On the other hand, we used function constructor to create MyFunc2, it becomes an instance of Function constructor.That's why instanceof also resolves to true.

What's safer to use ?

As we can see in both cases typeof operator can successfully asserted that we are dealing with a function here,it is safer than instanceof. instanceof will fail in case of function declaration because function declarations are not an instance of Function constructor.

Best practice :

As Gary Rafferty suggested, the best way should be using both typeof and instanceof together.

  function isFunction(functionItem) {

        return typeof(functionItem) == 'function' || functionItem instanceof Function;

  }

  isFunction(MyFunc) // invoke it by passing our test function as parameter

Facebook no longer supports custom parameters in sharer.php

I would simply make the assignment happen in the ng-mouseover and ng-mouseleave; no need to bother js file :)

<ul ng-repeat="task in tasks">
    <li ng-mouseover="hoverEdit = true" ng-mouseleave="hoverEdit = false">{{task.name}}</li>
    <span ng-show="hoverEdit"><a>Edit</a></span>
</ul>

The Status Value being returned by a Stored Procedure can only be an INT datatype. You cannot return other datatypes in the RETURN statement.

From Lesson 2: Designing Stored Procedures:

Every stored procedure can return an integer value known as the execution status value or return code.

If you still want a table returned from the SP, you'll either have to work the record set returned from a SELECT within the SP or tie into an OUTPUT variable that passes an XML datatype.

Using Numpy's fancy indexing:

>>> test
array([ 1, 23,  4,  6,  7,  8])

>>> test[::-1]  # test, reversed
array([ 8,  7,  6,  4, 23,  1])

>>> numpy.vstack([test, test[::-1]])  # stack test and its reverse
array([[ 1, 23,  4,  6,  7,  8],
       [ 8,  7,  6,  4, 23,  1]])

>>> # transpose, then take the first half;
>>> # +1 to cater to odd-length arrays
>>> numpy.vstack([test, test[::-1]]).T[:(len(test) + 1) // 2]
array([[ 1,  8],
       [23,  7],
       [ 4,  6]])

vstack copies the array, but all the other operations are constant-time pointer tricks (including reversal) and hence are very fast.

From a security point of view, I'd go for OAuth 1. See OAuth 2.0 and the road to hell

quote from that link: "If you are currently using 1.0 successfully, ignore 2.0. It offers no real value over 1.0 (I’m guessing your client developers have already figured out 1.0 signatures by now).

If you are new to this space, and consider yourself a security expert, use 2.0 after careful examination of its features. If you are not an expert, either use 1.0 or copy the 2.0 implementation of a provider you trust to get it right (Facebook’s API documents are a good place to start). 2.0 is better for large scale, but if you are running a major operation, you probably have some security experts on site to figure it all out for you."

Given that we are in a php code context and the variable $url contains the link the user wants to share, you can try this to use a custom image :

<a class="facebook-share-button" href="https://www.facebook.com/sharer/sharer.php?u=<?php echo urlencode($url); ?>" target="_blank"><img src="/img/facebook-share-button.png" /></a>

or this for just plain text :

<a class="facebook-share-button" href="https://www.facebook.com/sharer/sharer.php?u=<?php echo urlencode($url); ?>" target="_blank">share</a>

You can also style the link purely with css.

The html code :

<a class="facebook-share-button" href="https://www.facebook.com/sharer/sharer.php?u=<?php echo urlencode($url); ?>" target="_blank"></a>

The css code :

.facebook-share-button {
    background-image: url("/img/facebook-share-button.png");
    display: inline-block;
    height: 32px;
    width: 32px;
}

.facebook-share-button:active,
.facebook-share-button:focus,
.facebook-share-button:hover {
    background-image: url("/img/facebook-share-button-hover.png");
}

You might have to use another batch file first to launch the second with admin rights.

In the first use

runas /noprofile /user:mymachine\administrator yourbatchfile.bat

When using JSON dictionaries:

#define isNull(value) value == nil || [value isKindOfClass:[NSNull class]]

This post is high up when you google that error message, which I got when installing security patch KB4505224 on SQL Server 2017 Express i.e. None of the above worked for me, but did consume several hours trying.

The solution for me, partly from here was:

1. uninstall SQL Server
2. in Regional Settings / Management / System Locale, "Beta: UTF-8 support" should be OFF
3. re-install SQL Server
4. Let Windows install the patch.

And all was well.

More on this here.

You can use function: wc_get_page_id( 'cart' ) to get the ID of the page. This function will use the page setup as 'cart' page and not the slug. Meaning it will keep working also when you setup a different url for your 'cart' on the settings page. This works for all kind of Woocommerce special page, like 'checkout', 'shop' etc.

example:

if (wc_get_page_id( 'cart' ) == get_the_ID()) {
  // Do something.
}

On OS X, you need to take into account existing window decorations. They add 22 pixels to the height. So on a JFrame, you need to tell the program this:

frame.setSize(width, height + 22);

If you're looking for a space, that would be " " (one space).

If you're looking for one or more, it's " *" (that's two spaces and an asterisk) or " +" (one space and a plus).

If you're looking for common spacing, use "[ X]" or "[ X][ X]*" or "[ X]+" where X is the physical tab character (and each is preceded by a single space in all those examples).

These will work in every* regex engine I've ever seen (some of which don't even have the one-or-more "+" character, ugh).

If you know you'll be using one of the more modern regex engines, "\s" and its variations are the way to go. In addition, I believe word boundaries match start and end of lines as well, important when you're looking for words that may appear without preceding or following spaces.

For PHP specifically, this page may help.

From your edit, it appears you want to remove all non valid characters The start of this is (note the space inside the regex):

$newtag = preg_replace ("/[^a-zA-Z0-9 ]/", "", $tag);
#                                    ^ space here

If you also want trickery to ensure there's only one space between each word and none at the start or end, that's a little more complicated (and probably another question) but the basic idea would be:

$newtag = preg_replace ("/ +/", " ", $tag); # convert all multispaces to space
$newtag = preg_replace ("/^ /", "", $tag);  # remove space from start
$newtag = preg_replace ("/ $/", "", $tag);  # and end

Let me solve it for ya.

• Get into the sql.
• Enter the following thing.

SET GLOBAL validate_password.length = 4;
SET GLOBAL validate_password.mixed_case_count = 0;
SET GLOBAL validate_password.number_count = 0;
SET GLOBAL validate_password.policy = LOW;
SET GLOBAL validate_password.special_char_count = 0;
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'test';

Only for testing purposes.

your code would be

a = [0,88,26,3,48,85,65,16,97,83,91]

ind_pos = [a[1],a[5],a[7]]

print(ind_pos)

you get [88, 85, 16]

Maybe this will help someone else, but I've seen this error when the RHS of the mapping contains a colon without enclosing quotes, such as:

someKey: another key: Change to make today: work out more

should be

someKey: another key: "Change to make today: work out more"

Since C++11, some new templates are introduced to help reduce the pain when dealing with array length. All of them are defined in header <type_traits>.

• std::rank<T>::value

  If T is an array type, provides the member constant value equal to the number of dimensions of the array. For any other type, value is 0.

• std::extent<T, N>::value

  If T is an array type, provides the member constant value equal to the number of elements along the Nth dimension of the array, if N is in [0, std::rank<T>::value). For any other type, or if T is array of unknown bound along its first dimension and N is 0, value is 0.

• std::remove_extent<T>::type

  If T is an array of some type X, provides the member typedef type equal to X, otherwise type is T. Note that if T is a multidimensional array, only the first dimension is removed.

• std::remove_all_extents<T>::type

  If T is a multidimensional array of some type X, provides the member typedef type equal to X, otherwise type is T.

To get the length on any dimension of a multidimential array, decltype could be used to combine with std::extent. For example:

#include <iostream>
#include <type_traits> // std::remove_extent std::remove_all_extents std::rank std::extent

template<class T, size_t N>
constexpr size_t length(T(&)[N]) { return N; }

template<class T, size_t N>
constexpr size_t length2(T(&arr)[N]) { return sizeof(arr) / sizeof(*arr); }

int main()
{
    int a[5][4][3]{{{1,2,3}, {4,5,6}}, { }, {{7,8,9}}};

    // New way
    constexpr auto l1 = std::extent<decltype(a)>::value;     // 5
    constexpr auto l2 = std::extent<decltype(a), 1>::value;  // 4
    constexpr auto l3 = std::extent<decltype(a), 2>::value;  // 3
    constexpr auto l4 = std::extent<decltype(a), 3>::value;  // 0

    // Mixed way
    constexpr auto la = length(a);
    //constexpr auto lpa = length(*a);  // compile error
    //auto lpa = length(*a);  // get at runtime
    std::remove_extent<decltype(a)>::type pa;  // get at compile time
    //std::remove_reference<decltype(*a)>::type pa;  // same as above
    constexpr auto lpa = length(pa);
    std::cout << la << ' ' << lpa << '\n';

    // Old way
    constexpr auto la2 = sizeof(a) / sizeof(*a);
    constexpr auto lpa2 = sizeof(*a) / sizeof(**a);
    std::cout << la2 << ' ' << lpa2 << '\n';

    return 0;
}

BTY, to get the total number of elements in a multidimentional array:

constexpr auto l = sizeof(a) / sizeof(std::remove_all_extents<decltype(a)>::type);

Or put it in a function template:

#include <iostream>
#include <type_traits>?    

template<class T>
constexpr size_t len(T &a)
{
    return sizeof(a) / sizeof(typename std::remove_all_extents<T>::type);
}

int main()
{
    int a[5][4][3]{{{1,2,3}, {4,5,6}}, { }, {{7,8,9}}};
    constexpr auto ttt = len(a);
    int i;
    std::cout << ttt << ' ' << len(i) << '\n';?    
    return 0;
}

More examples of how to use them could be found by following the links.

For me the above solutions were close but added some unwanted /n's and dtype:object, so here's a modified version:

df.groupby(['name', 'month'])['text'].apply(lambda text: ''.join(text.to_string(index=False))).str.replace('(\\n)', '').reset_index()

You should use a DialogFragment instead.

Without Iframe We can do this by JQuery but it will give you only HTML page source and no dynamic links or html tags will display. Almost same as php solution but in JQuery :) Code---

var purl = "http://www.othersite.com";
$.getJSON('http://whateverorigin.org/get?url=' +
    encodeURIComponent(purl) + '&callback=?',
    function (data) {
    $('#viewer').html(data.contents);
});

Dont get confusion : simply remember

1. Statement is used for static queries like DDLs i.e. create,drop,alter and prepareStatement is used for dynamic queries i.e. DML query.
2. In Statement, the query is not precompiled while in prepareStatement query is precompiled, because of this prepareStatement is time efficient.
3. prepareStatement takes argument at the time of creation while Statement does not take arguments. For Example if you want to create table and insert element then :: Create table (static) by using Statement and Insert element (dynamic)by using prepareStatement.

Below is how it's working for me on Python 3.6:

import requests
import urllib3

# Suppress InsecureRequestWarning: Unverified HTTPS
urllib3.disable_warnings()

Call it like this:

foo(*ob);

Note that there is no casting going on here, as suggested in your question title. All we have done is de-referenced the pointer to the object which we then pass to the function.

• socket.isConnected() returns always true once the client connects (and even after the disconnect) weird !!
• socket.getInputStream().read()
  • makes the thread wait for input as long as the client is connected and therefore makes your program not do anything - except if you get some input
  • returns -1 if the client disconnected
• socket.getInetAddress().isReachable(int timeout): From isReachable(int timeout)

  Test whether that address is reachable. Best effort is made by the implementation to try to reach the host, but firewalls and server configuration may block requests resulting in a unreachable status while some specific ports may be accessible. A typical implementation will use ICMP ECHO REQUESTs if the privilege can be obtained, otherwise it will try to establish a TCP connection on port 7 (Echo) of the destination host.

The way I am doing is using Emacs with docker package installed. I would recommend Spacemacs version of Emacs. I would follow the following steps:

1) Install Emacs (Instruction) and install Spacemacs (Instruction)

2) Add docker in your .spacemacs file

3) Start Emacs

4) Find file (SPC+f+f) and type /docker:<container-id>:/<path of dir/file in the container>

5) Now your emacs will use the container environment to edit the files

Another simple way to do this: go on the origin branch and do a merge --squash. This command doesn't do the "squashed" commit. when you do it, all commit messages of yourBranch will be gathered.

$ git checkout master
$ git merge --squash yourBranch
$ git commit # all commit messages of yourBranch in one, really useful
 > [status 5007e77] Squashed commit of the following: ...

If you want the click handler to work for an element that gets loaded dynamically, then you set the event handler on a parent object (that does not get loaded dynamically) and give it a selector that matches your dynamic object like this:

$('#parent').on("click", "#child", function() {});

The event handler will be attached to the #parent object and anytime a click event bubbles up to it that originated on #child, it will fire your click handler. This is called delegated event handling (the event handling is delegated to a parent object).

It's done this way because you can attach the event to the #parent object even when the #child object does not exist yet, but when it later exists and gets clicked on, the click event will bubble up to the #parent object, it will see that it originated on #child and there is an event handler for a click on #child and fire your event.

It took a while to put together a solution for this, but have found this is the easiest way to get it to work in the way that you describe. There could be better ways to do this, but since you haven't posted your activity code I will have to improvise and assume you have a list like this at the start of your activity:

private List<String> items = db.getItems();

ExampleActivity.java

private List<String> items;

private Menu menu;

@Override
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public boolean onCreateOptionsMenu(Menu menu) {

    getMenuInflater().inflate(R.menu.example, menu);

    this.menu = menu;

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {

        SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);

        SearchView search = (SearchView) menu.findItem(R.id.search).getActionView();

        search.setSearchableInfo(manager.getSearchableInfo(getComponentName()));

        search.setOnQueryTextListener(new OnQueryTextListener() { 

            @Override 
            public boolean onQueryTextChange(String query) {

                loadHistory(query);

                return true; 

            } 

        });

    }

    return true;

}

// History
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
private void loadHistory(String query) {

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {

        // Cursor
        String[] columns = new String[] { "_id", "text" };
        Object[] temp = new Object[] { 0, "default" };

        MatrixCursor cursor = new MatrixCursor(columns);

        for(int i = 0; i < items.size(); i++) {

            temp[0] = i;
            temp[1] = items.get(i);

            cursor.addRow(temp);

        }

        // SearchView
        SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);

        final SearchView search = (SearchView) menu.findItem(R.id.search).getActionView();

        search.setSuggestionsAdapter(new ExampleAdapter(this, cursor, items));

    }

}

Now you need to create an adapter extended from CursorAdapter:

ExampleAdapter.java

public class ExampleAdapter extends CursorAdapter {

    private List<String> items;

    private TextView text;

    public ExampleAdapter(Context context, Cursor cursor, List<String> items) {

        super(context, cursor, false);

        this.items = items;

    }

    @Override
    public void bindView(View view, Context context, Cursor cursor) {

        text.setText(items.get(cursor.getPosition()));

    }

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {

        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View view = inflater.inflate(R.layout.item, parent, false);

        text = (TextView) view.findViewById(R.id.text);

        return view;

    }

}

A better way to do this is if your list data is from a database, you can pass the Cursor returned by database functions directly to ExampleAdapter and use the relevant column selector to display the column text in the TextView referenced in the adapter.

Please note: when you import CursorAdapter don't import the Android support version, import the standard android.widget.CursorAdapter instead.

The adapter will also require a custom layout:

res/layout/item.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <TextView
        android:id="@+id/item"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</RelativeLayout>

You can now customize list items by adding additional text or image views to the layout and populating them with data in the adapter.

This should be all, but if you haven't done this already you need a SearchView menu item:

res/menu/example.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:id="@+id/search"
        android:title="@string/search"
        android:showAsAction="ifRoom"
        android:actionViewClass="android.widget.SearchView" />

</menu>

Then create a searchable configuration:

res/xml/searchable.xml

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/search"
    android:hint="@string/search" >
</searchable>

Finally add this inside the relevant activity tag in the manifest file:

AndroidManifest.xml

<intent-filter>
    <action android:name="android.intent.action.SEARCH" />
</intent-filter>

<meta-data
    android:name="android.app.default_searchable"
    android:value="com.example.ExampleActivity" />
<meta-data
    android:name="android.app.searchable"
    android:resource="@xml/searchable" />

Please note: The @string/search string used in the examples should be defined in values/strings.xml, also don't forget to update the reference to com.example for your project.

Like that you can set DataTextField and DataValueField of DropDownList using "Key" and "Value" texts :

    Dictionary<string, string> list = new Dictionary<string, string>();
    list.Add("item 1", "Item 1");
    list.Add("item 2", "Item 2");
    list.Add("item 3", "Item 3");
    list.Add("item 4", "Item 4");

    ddl.DataSource = list;
    ddl.DataTextField = "Value";
    ddl.DataValueField = "Key";
    ddl.DataBind();

You could use lists() :

test::where('id' ,'>' ,0)->lists('id')->toArray();

NOTE : Better if you define your models in Studly Case format, e.g Test.

You could also use get() :

test::where('id' ,'>' ,0)->get('id');

UPDATE: (For versions >= 5.2)

The lists() method was deprecated in the new versions >= 5.2, now you could use pluck() method instead :

test::where('id' ,'>' ,0)->pluck('id')->toArray();

NOTE: If you need a string, for example in a blade, you can use function without the toArray() part, like:

test::where('id' ,'>' ,0)->pluck('id');

I was able to use the name attribute that you described in your example for the loop I am working on and it worked, perhaps because I created unique ids? I'm still considering whether I should switch to an editor template instead as mentioned in the links in another answer.

    @Html.RadioButtonFor(modelItem => item.Answers.AnswerYesNo, "true", new {Name = item.Description.QuestionId, id = string.Format("CBY{0}", item.Description.QuestionId), onclick = "setDescriptionVisibility(this)" }) Yes

    @Html.RadioButtonFor(modelItem => item.Answers.AnswerYesNo, "false", new { Name = item.Description.QuestionId, id = string.Format("CBN{0}", item.Description.QuestionId), onclick = "setDescriptionVisibility(this)" } ) No

This answer is a bit orthogonal to the the OP, but --

libsass bindings don't install properly with the node-sass wrapper on Node v4.0.0. I got the same error message as in the question (Error: 'libsass' bindings not found. Try reinstalling 'node-sass') but I ended up uninstalling Node v4.0.0 and installing v0.12.7 using nvm, via this script:

https://gist.github.com/brock/5b1b70590e1171c4ab54

and now libsass and node-sass are behaving properly.

Go to Tools|options|keymap. Search for 'zoom in text' and set your preferred key. I've set alt+plus and alt+minus.

"How can I directly (without saving the file on 2nd server) download the file from 1st server to client's machine?"

Just use the Client API and get the InputStream from the response

Client client = ClientBuilder.newClient();
String url = "...";
final InputStream responseStream = client.target(url).request().get(InputStream.class);

There are two flavors to get the InputStream. You can also use

Response response = client.target(url).request().get();
InputStream is = (InputStream)response.getEntity();

Which one is the more efficient? I'm not sure, but the returned InputStreams are different classes, so you may want to look into that if you care to.

From 2nd server I can get a ByteArrayOutputStream to get the file from 1st server, can I pass this stream further to the client using the REST service?

So most of the answers you'll see in the link provided by @GradyGCooper seem to favor the use of StreamingOutput. An example implementation might be something like

final InputStream responseStream = client.target(url).request().get(InputStream.class);
System.out.println(responseStream.getClass());
StreamingOutput output = new StreamingOutput() {
    @Override
    public void write(OutputStream out) throws IOException, WebApplicationException {  
        int length;
        byte[] buffer = new byte[1024];
        while((length = responseStream.read(buffer)) != -1) {
            out.write(buffer, 0, length);
        }
        out.flush();
        responseStream.close();
    }   
};
return Response.ok(output).header(
        "Content-Disposition", "attachment, filename=\"...\"").build();

But if we look at the source code for StreamingOutputProvider, you'll see in the writeTo, that it simply writes the data from one stream to another. So with our implementation above, we have to write twice.

How can we get only one write? Simple return the InputStream as the Response

final InputStream responseStream = client.target(url).request().get(InputStream.class);
return Response.ok(responseStream).header(
        "Content-Disposition", "attachment, filename=\"...\"").build();

If we look at the source code for InputStreamProvider, it simply delegates to ReadWriter.writeTo(in, out), which simply does what we did above in the StreamingOutput implementation

 public static void writeTo(InputStream in, OutputStream out) throws IOException {
    int read;
    final byte[] data = new byte[BUFFER_SIZE];
    while ((read = in.read(data)) != -1) {
        out.write(data, 0, read);
    }
}

Asides:

• Client objects are expensive resources. You may want to reuse the same Client for request. You can extract a WebTarget from the client for each request.

  WebTarget target = client.target(url);
  InputStream is = target.request().get(InputStream.class);
  

  I think the WebTarget can even be shared. I can't find anything in the Jersey 2.x documentation (only because it is a larger document, and I'm too lazy to scan through it right now :-), but in the Jersey 1.x documentation, it says the Client and WebResource (which is equivalent to WebTarget in 2.x) can be shared between threads. So I'm guessing Jersey 2.x would be the same. but you may want to confirm for yourself.

• You don't have to make use of the Client API. A download can be easily achieved with the java.net package APIs. But since you're already using Jersey, it doesn't hurt to use its APIs

• The above is assuming Jersey 2.x. For Jersey 1.x, a simple Google search should get you a bunch of hits for working with the API (or the documentation I linked to above)

UPDATE

I'm such a dufus. While the OP and I are contemplating ways to turn a ByteArrayOutputStream to an InputStream, I missed the simplest solution, which is simply to write a MessageBodyWriter for the ByteArrayOutputStream

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.lang.annotation.Annotation;
import java.lang.reflect.Type;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.MultivaluedMap;
import javax.ws.rs.ext.MessageBodyWriter;
import javax.ws.rs.ext.Provider;

@Provider
public class OutputStreamWriter implements MessageBodyWriter<ByteArrayOutputStream> {

    @Override
    public boolean isWriteable(Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType) {
        return ByteArrayOutputStream.class == type;
    }

    @Override
    public long getSize(ByteArrayOutputStream t, Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType) {
        return -1;
    }

    @Override
    public void writeTo(ByteArrayOutputStream t, Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType,
            MultivaluedMap<String, Object> httpHeaders, OutputStream entityStream)
            throws IOException, WebApplicationException {
        t.writeTo(entityStream);
    }
}

Then we can simply return the ByteArrayOutputStream in the response

return Response.ok(baos).build();

D'OH!

UPDATE 2

Here are the tests I used (

Resource class

@Path("test")
public class TestResource {

    final String path = "some_150_mb_file";

    @GET
    @Produces(MediaType.APPLICATION_OCTET_STREAM)
    public Response doTest() throws Exception {
        InputStream is = new FileInputStream(path);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        int len;
        byte[] buffer = new byte[4096];
        while ((len = is.read(buffer, 0, buffer.length)) != -1) {
            baos.write(buffer, 0, len);
        }
        System.out.println("Server size: " + baos.size());
        return Response.ok(baos).build();
    }
}

Client test

public class Main {
    public static void main(String[] args) throws Exception {
        Client client = ClientBuilder.newClient();
        String url = "http://localhost:8080/api/test";
        Response response = client.target(url).request().get();
        String location = "some_location";
        FileOutputStream out = new FileOutputStream(location);
        InputStream is = (InputStream)response.getEntity();
        int len = 0;
        byte[] buffer = new byte[4096];
        while((len = is.read(buffer)) != -1) {
            out.write(buffer, 0, len);
        }
        out.flush();
        out.close();
        is.close();
    }
}

UPDATE 3

So the final solution for this particular use case was for the OP to simply pass the OutputStream from the StreamingOutput's write method. Seems the third-party API, required a OutputStream as an argument.

StreamingOutput output = new StreamingOutput() {
    @Override
    public void write(OutputStream out) {
        thirdPartyApi.downloadFile(.., .., .., out);
    }
}
return Response.ok(output).build();

Not quite sure, but seems the reading/writing within the resource method, using ByteArrayOutputStream`, realized something into memory.

The point of the downloadFile method accepting an OutputStream is so that it can write the result directly to the OutputStream provided. For instance a FileOutputStream, if you wrote it to file, while the download is coming in, it would get directly streamed to the file.

It's not meant for us to keep a reference to the OutputStream, as you were trying to do with the baos, which is where the memory realization comes in.

So with the way that works, we are writing directly to the response stream provided for us. The method write doesn't actually get called until the writeTo method (in the MessageBodyWriter), where the OutputStream is passed to it.

You can get a better picture looking at the MessageBodyWriter I wrote. Basically in the writeTo method, replace the ByteArrayOutputStream with StreamingOutput, then inside the method, call streamingOutput.write(entityStream). You can see the link I provided in the earlier part of the answer, where I link to the StreamingOutputProvider. This is exactly what happens

This answer needs to be updated to work with Express 4.0. Here is how I got the separate http server to work:

var express = require('express');
var http = require('http');
var https = require('https');

// Primary https app
var app = express()
var port = process.env.PORT || 3000;
app.set('env', 'development');
app.set('port', port);
var router = express.Router();
app.use('/', router);
// ... other routes here
var certOpts = {
    key: '/path/to/key.pem',
    cert: '/path/to/cert.pem'
};
var server = https.createServer(certOpts, app);
server.listen(port, function(){
    console.log('Express server listening to port '+port);
});


// Secondary http app
var httpApp = express();
var httpRouter = express.Router();
httpApp.use('*', httpRouter);
httpRouter.get('*', function(req, res){
    var host = req.get('Host');
    // replace the port in the host
    host = host.replace(/:\d+$/, ":"+app.get('port'));
    // determine the redirect destination
    var destination = ['https://', host, req.url].join('');
    return res.redirect(destination);
});
var httpServer = http.createServer(httpApp);
httpServer.listen(8080);

As per the documentation: This allows you to switch from the default ASCII to other encodings such as UTF-8, which the Python runtime will use whenever it has to decode a string buffer to unicode.

This function is only available at Python start-up time, when Python scans the environment. It has to be called in a system-wide module, sitecustomize.py, After this module has been evaluated, the setdefaultencoding() function is removed from the sys module.

The only way to actually use it is with a reload hack that brings the attribute back.

Also, the use of sys.setdefaultencoding() has always been discouraged, and it has become a no-op in py3k. The encoding of py3k is hard-wired to "utf-8" and changing it raises an error.

I suggest some pointers for reading:

I had this problem too on a win7 machine. I wanted to update the jre with a jdk. So i deleted the jre folder and downloaded and unzipped the new jdk. The issue was i manually deleted the jre folder, when instead i should've uninstalled it. This leaves a bunch of registry entries that still point to the old jre. Somehow eclipse still wants to use the old jre. I couldn't uninstall the old java vm, i kept getting this error:

Error 1723. There is a problem with this Windows Installer package. A DLL required for this install to complete could not be run. Contact your support personnel or package vendor

So i had to use this MS utility to fix the uninstall:

http://support.microsoft.com/kb/2438651/

Then i had to install again the vm. I installed to the same location the original one was at, to avoid losing another hour! After that eclipse started correctly.

When you open an Eclipse workspace from within a clearcase view and try to rename the project, you will often get the pop-up warning ... “Resource ‘project’ is out of sync with the file system”. If refreshing the project does not fix the problem, then do the following workaround: a. Open workspace WITHOUT being in a view b. Select the project in Project Explorer c. ClearCase -> Associate Project (project should now look like project [] ) d. Right click project -> Refresh (vob sub-folders should now be empty) e. Right click project -> Rename ... f. Enter New name

Now you can close the workspace, reopen it in a view and refresh the project. You may also dissociate the project if you prefer the project not to be associated with the vob.

When the use logs in, put its username in the session:

`session.setAttribute("USER", username);`

At the beginning of each page you can do this:

<%
String username = (String)session.getAttribute("USER");
if(username==null) 
// if session is expired, forward it to login page
%>
<jsp:forward page="Login.jsp" />
<% { } %>

Like other answers, use https instead of ssh was the solution.

I post an answer to give a concrete example of a possible solution. I solved this issue with bitbucket when I changed remote url to HTTPS with this command line:

git remote set-url origin <bitbucket_URL>

After that, I could push the content to the repository with this command:

git push -u origin --all

And then I could also use Sourcetree

If you want to search for the last instance of a string in a text, you can run rfind.

Example:

   s="Hello"
   print s.rfind('l')

output: 3

*no import needed

Complete syntax:

stringEx.rfind(substr, beg=0, end=len(stringEx))

I know this is question is really old, but I found an easy and simple jQuery solution in css-tricks. That's the one I'm using now.

$(function() {
  $('a[href*=#]:not([href=#])').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top
        }, 1000);
        return false;
      }
    }
  });
});

I asume you have connected to your database already.

$sql = "SELECT * FROM my_table";
$result = mysql_query($sql);

$row = 1; // 1-based index
while($row_data = mysql_fetch_assoc($result)) {
    $col = 0;
    foreach($row_data as $key=>$value) {
        $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value);
        $col++;
    }
    $row++;
}

I realize that this question is quite old but I had a similar issue. The following did what I wanted:

class Agent(object):
    _agents = dict()

    def __new__(cls, *p):
        number = p[0]
        if not number in cls._agents:
            cls._agents[number] = object.__new__(cls)
        return cls._agents[number]

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

    def __eq__(self, rhs):
        return self.number == rhs.number

Agent("a") is Agent("a") == True

The European Central Bank (ECB) also has the most reliable free feed that I know of. It contains approx 28 currencies and is updated at least daily.

Example of using PHP to get a value from a form:

Put this in foobar.php:

<html>
<body>
  <form action="foobar_submit.php" method="post">
    <input name="my_html_input_tag"  value="PILLS HERE"/>

    <input type="submit" name="my_form_submit_button" 
           value="Click here for penguins"/>

    </form>
</body>
</html>

Read the above code so you understand what it is doing:

"foobar.php is an HTML document containing an HTML form. When the user presses the submit button inside the form, the form's action property is run: foobar_submit.php. The form will be submitted as a POST request. Inside the form is an input tag with the name "my_html_input_tag". It's default value is "PILLS HERE". That causes a text box to appear with text: 'PILLS HERE' on the browser. To the right is a submit button, when you click it, the browser url changes to foobar_submit.php and the below code is run.

Put this code in foobar_submit.php in the same directory as foobar.php:

<?php
  echo $_POST['my_html_input_tag'];
  echo "<br><br>";
  print_r($_POST); 
?>

Read the above code so you know what its doing:

The HTML form from above populated the $_POST superglobal with key/value pairs representing the html elements inside the form. The echo prints out the value by key: 'my_html_input_tag'. If the key is found, which it is, its value is returned: "PILLS HERE".

Then print_r prints out all the keys and values from $_POST so you can peek as to what else is in there.

The value of the input tag with name=my_html_input_tag was put into the $_POST and you retrieved it inside another PHP file.

This function will tell you the x,y position of the element relative to the page. Basically you have to loop up through all the element's parents and add their offsets together.

function getPos(el) {
    // yay readability
    for (var lx=0, ly=0;
         el != null;
         lx += el.offsetLeft, ly += el.offsetTop, el = el.offsetParent);
    return {x: lx,y: ly};
}

However, if you just wanted the x,y position of the element relative to its container, then all you need is:

var x = el.offsetLeft, y = el.offsetTop;

To put an element directly below this one, you'll also need to know its height. This is stored in the offsetHeight/offsetWidth property.

var yPositionOfNewElement = el.offsetTop + el.offsetHeight + someMargin;

Never mind, I found the answer.

This will do the trick.

Dim colIndex As Long    
colIndex = Application.Match(colName, Range(Cells(rowIndex, 1), Cells(rowIndex, 100)), 0)

Use the CSS pointer-events:none on fields you want to "disable" (possibly together with a greyed background) which allows the POST action, like:

<input type="text" class="disable">

.disable{
pointer-events:none;
background:grey;
}

Since arrays must be indexed with integers, the maximum length of an array is Integer.MAX_INT (2³¹-1, or 2 147 483 647). This is assuming you have enough memory to hold an array of that size, of course.

Since you have not mentioned what needs to be copied, I have left that section empty in the code below.

Also you don't need to move the email to the folder first and then run the macro in that folder. You can run the macro on the incoming mail and then move it to the folder at the same time.

This will get you started. I have commented the code so that you will not face any problem understanding it.

First paste the below mentioned code in the outlook module.

Then

1. Click on Tools~~>Rules and Alerts
2. Click on "New Rule"
3. Click on "start from a blank rule"
4. Select "Check messages When they arrive"
5. Under conditions, click on "with specific words in the subject"
6. Click on "specific words" under rules description.
7. Type the word that you want to check in the dialog box that pops up and click on "add".
8. Click "Ok" and click next
9. Select "move it to specified folder" and also select "run a script" in the same box
10. In the box below, specify the specific folder and also the script (the macro that you have in module) to run.
11. Click on finish and you are done.

When the new email arrives not only will the email move to the folder that you specify but data from it will be exported to Excel as well.

Use ByteArrayInputStream:

InputStream is = new ByteArrayInputStream(decodedBytes);

Opaque responses can't be accessed by JavaScript, but you can still cache them with the Cache API and respond with them in the fetch event handler in a service worker. So they're useful for making your app offline, also for resources that you can't control (e.g. resources on a CDN that doesn't set the CORS headers).

The following worked for me (tested on react native 0.38 and 0.40):

npm install -g ios-deploy
# Run on a connected device, e.g. Max's iPhone:
react-native run-ios --device "Max's iPhone"

If you try to run run-ios, you will see that the script recommends to do npm install -g ios-deploy when it reach install step after building.

While the documentation on the various commands that react-native offers is a little sketchy, it is worth going to react-native/local-cli. There, you can see all the commands available and the code that they run - you can thus work out what switches are available for undocumented commands.

For a repository setting solution, that can be redistributed to all developers, check out the text attribute in the .gitattributes file. This way, developers dont have to manually set their own line endings on the repository, and because different repositories can have different line ending styles, global core.autocrlf is not the best, at least in my opinion.

For example unsetting this attribute on a given path [. - text] will force git not to touch line endings when checking in and checking out. In my opinion, this is the best behavior, as most modern text editors can handle both type of line endings. Also, if you as a developer still want to do line ending conversion when checking in, you can still set the path to match certain files or set the eol attribute (in .gitattributes) on your repository.

Also check out this related post, which describes .gitattributes file and text attribute in more detail: What's the best CRLF (carriage return, line feed) handling strategy with Git?

Try installing via :app:installDebug. If it works then it is related to Android Studio's caches. I removed .gradle/ folder inside my project and it works.

You do know that DataRow is the row of a DataTable correct?

What you currently have already loop through each row. You just have to keep track of how many rows there are in order to get the current row.

int i = 0;
int index = 0;
foreach (DataRow row in dt.Rows) 
{
index = i;
// do stuff
i++;
} 

How about using name attribute for old browsers and id attribute to the new browsers. Both options will be used and fallback method will be implemented by default!!!

== is what you want, "is" just happens to work on your examples.

The recommended way is to use requests module:

#!/usr/bin/env python
import requests # $ python -m pip install requests
####from pip._vendor import requests # bundled with python

url = 'https://httpbin.org/hidden-basic-auth/user/passwd'
user, password = 'user', 'passwd'

r = requests.get(url, auth=(user, password)) # send auth unconditionally
r.raise_for_status() # raise an exception if the authentication fails

Here's a single source Python 2/3 compatible urllib2-based variant:

#!/usr/bin/env python
import base64
try:
    from urllib.request import Request, urlopen
except ImportError: # Python 2
    from urllib2 import Request, urlopen

credentials = '{user}:{password}'.format(**vars()).encode()
urlopen(Request(url, headers={'Authorization': # send auth unconditionally
    b'Basic ' + base64.b64encode(credentials)})).close()

Python 3.5+ introduces HTTPPasswordMgrWithPriorAuth() that allows:

..to eliminate unnecessary 401 response handling, or to unconditionally send credentials on the first request in order to communicate with servers that return a 404 response instead of a 401 if the Authorization header is not sent..

#!/usr/bin/env python3
import urllib.request as urllib2

password_manager = urllib2.HTTPPasswordMgrWithPriorAuth()
password_manager.add_password(None, url, user, password,
                              is_authenticated=True) # to handle 404 variant
auth_manager = urllib2.HTTPBasicAuthHandler(password_manager)
opener = urllib2.build_opener(auth_manager)

opener.open(url).close()

It is easy to replace HTTPBasicAuthHandler() with ProxyBasicAuthHandler() if necessary in this case.

You can use this :

     IF OBJECT_ID (N'dbo.T', N'U') IS NOT NULL 
        BEGIN 
            print 'deleted table';
            drop table t 
        END
     else 
        begin 
            print 'table not found' 
        end

 Create table t (id int identity(1,1) not null, name varchar(30) not null, lastname varchar(25) null)
 insert into t( name, lastname) values('john','doe');
 insert into t( name, lastname) values('rose',NULL);

 Select * from t
1   john    doe
2   rose    NULL

 -- clean
 drop table t

The primary purpose of AF_INET was to allow for other possible network protocols or address families (AF is for address family; PF_INET is for the (IPv4) internet protocol family). For example, there probably are a few Netware SPX/IPX networks around still; there were other network systems like DECNet, StarLAN and SNA, not to mention the ill-begotten ISO OSI (Open Systems Interconnection), and these did not necessarily use the now ubiquitous IP address to identify the peer host in network connections.

The ubiquitous alternative to AF_INET (which, in retrospect, should have been named AF_INET4) is AF_INET6, for the IPv6 address family. IPv4 uses 32-bit addresses; IPv6 uses 128-bit addresses.

You may see some other values - but they are unusual. It is there to allow for alternatives and future directions. The sockets interface is actually very general indeed - which is one of the reasons it has thrived where other networking interfaces have withered.

Life has (mostly) gotten simpler - be grateful.

I have found this class very helpful to handle with resources. It has some defined methods to deal with dimens, colors, drawables and strings, like this one:

public static String getString(Context context, String stringId) {
    int sid = getStringId(context, stringId);
    if (sid > 0) {
        return context.getResources().getString(sid);
    } else {
        return "";
    }
}

The faster way is to insert distinct rows into a temporary table. Using delete, it took me a few hours to remove duplicates from a table of 8 million rows. Using insert and distinct, it took just 13 minutes.

CREATE TABLE tempTableName LIKE tableName;  
CREATE INDEX ix_all_id ON tableName(cellId,attributeId,entityRowId,value);  
INSERT INTO tempTableName(cellId,attributeId,entityRowId,value) SELECT DISTINCT cellId,attributeId,entityRowId,value FROM tableName;  
TRUNCATE TABLE tableName;
INSERT INTO tableName SELECT * FROM tempTableName; 
DROP TABLE tempTableName;  

Just wanted to point out that Haris's Answer might not work if some other background process is using the database, in my case it was delayed jobs, I did:

script/delayed_job stop

And only then I was able to drop/reset the database.

You can also try this. Credits to the original author who has since removed the script

When you run a shell script, it's done in a sub-shell so it cannot affect the parent shell's environment. You want to source the script by doing:

. ./setfoo.sh

This executes it in the context of the current shell, not as a sub shell.

From the bash man page:

. filename [arguments]
source filename [arguments]

Read and execute commands from filename in the current shell environment and return the exit status of the last command executed from filename.

If filename does not contain a slash, file names in PATH are used to find the directory containing filename.

The file searched for in PATH need not be executable. When bash is not in POSIX mode, the current directory is searched if no file is found in PATH.

If the sourcepath option to the shopt builtin command is turned off, the PATH is not searched.

If any arguments are supplied, they become the positional parameters when filename is executed.

Otherwise the positional parameters are unchanged. The return status is the status of the last command exited within the script (0 if no commands are executed), and false if filename is not found or cannot be read.

No Need to manually start an application every time at time of development to implements changes use 'spring-boot-devtool' maven dependency.

Automatic Restart : To use the module you simply need to add it as a dependency in your Maven POM:

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
    </dependency>

When you have the spring-boot-devtools module included, any classpath file changes will automatically trigger an application restart. We do some tricks to try and keep restarts fast, so for many microservice style applications this technique might be good enough.

In webkit-based browsers(Safari and Chrome), -webkit-transform is ignored on inline elements.. Set display: inline-block; to make it work. For demonstration/testing purposes, you may also want to use a negative angle or a transformation-origin lest the text is rotated out of the visible area.

The following answer is not exactly optimal by any measure, but I needed something that maintains its position within the container whilst it stretches the inner div fully.

https://jsfiddle.net/fah5axm5/

$(function() {
    $(window).on('load resize', ppaFullWidth);

    function ppaFullWidth() {
        var $elements = $('[data-ppa-full-width="true"]');
        $.each( $elements, function( key, item ) {
            var $el = $(this);
            var $container = $el.closest('.container');
            var margin = parseInt($container.css('margin-left'), 10);
            var padding = parseInt($container.css('padding-left'), 10)
            var offset = margin + padding;

            $el.css({
                position: "relative",
                left: -offset,
                "box-sizing": "border-box",
                width: $(window).width(),
                "padding-left": offset + "px",
                "padding-right": offset + "px"
            });
        });
    }
});

For a period I had to extract the Media ID myself quite frequently, so I wrote my own script (very likely it's based on some of the examples here). Together with other small scripts I used frequently, I started to upload them on www.findinstaid.com for my own quick access.

I added the option to enter a username to get the media ID of the 12 most recent posts, or to enter a URL to get the media ID of a specific post.

If it's convenient, everyone can use the link (I don't have any adds or any other monetary interests in the website - I only have a referral link on the 'Audit' tab to www.auditninja.io which I do also own, but also on this site, there are no adds or monetary interests - just hobby projects).

That's the main concept. Have fun ;)

NSURL *url = [NSURL URLWithString:@"http://example.com/yourImage.png"];
NSData *data = [NSData dataWithContentsOfURL:url];
NSString *path = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
path = [path stringByAppendingString:@"/yourLocalImage.png"];
[data writeToFile:path atomically:YES];

100% security of the source code and resources is not possible in Android. But, you can make little bit difficult for the reverse engineer. You can find more details on this in below links:

Could someone explain to me, how to call the move method with the variable RIGHT

>>> myMissile = MissileDevice(myBattery)  # looks like you need a battery, don't know what that is, you figure it out.
>>> myMissile.move(MissileDevice.RIGHT)

If you have programmed in any other language with classes, besides python, this sort of thing

class Foo:
    bar = "baz"

is probably unfamiliar. In python, the class is a factory for objects, but it is itself an object; and variables defined in its scope are attached to the class, not the instances returned by the class. to refer to bar, above, you can just call it Foo.bar; you can also access class attributes through instances of the class, like Foo().bar.

Im utterly baffled about what 'self' refers too,

>>> class Foo:
...     def quux(self):
...         print self
...         print self.bar
...     bar = 'baz'
...
>>> Foo.quux
<unbound method Foo.quux>
>>> Foo.bar
'baz'
>>> f = Foo()
>>> f.bar
'baz'
>>> f
<__main__.Foo instance at 0x0286A058>
>>> f.quux
<bound method Foo.quux of <__main__.Foo instance at 0x0286A058>>
>>> f.quux()
<__main__.Foo instance at 0x0286A058>
baz
>>>

When you acecss an attribute on a python object, the interpreter will notice, when the looked up attribute was on the class, and is a function, that it should return a "bound" method instead of the function itself. All this does is arrange for the instance to be passed as the first argument.

You can try this

<a [attr.disabled]="someCondition ? true: null"></a>

That usually means that your friend does not have the Microsoft redistributable for Visual C++. I am of course assuming you are using VC++ and not MingW or another compiler. Since your friend does not have VS installed as well there is no guarantee he has the redist installed.

VC++ Distro

This is not 100% ideal, but if it is either too much of a pain to pass down props in children -> children fashion or create a Context.Provider/Context.Consumer just for this purpose), and you are dealing with another library which has it's own handler it runs before yours, you can also try:

   function myHandler(e) { 
        e.persist(); 
        e.nativeEvent.stopImmediatePropagation();
        e.stopPropagation(); 
   }

From what I understand, the event.persist method prevents an object from immediately being thrown back into React's SyntheticEvent pool. So because of that, the event passed in React actually doesn't exist by the time you reach for it! This happens in grandchildren because of the way React handle's things internally by first checking parent on down for SyntheticEvent handlers (especially if the parent had a callback).

As long as you are not calling persist on something which would create significant memory to keep creating events such as onMouseMove (and you are not creating some kind of Cookie Clicker game like Grandma's Cookies), it should be perfectly fine!

Also note: from reading around their GitHub occasionally, we should keep our eyes out for future versions of React as they may eventually resolve some of the pain with this as they seem to be going towards making folding React code in a compiler/transpiler.

Pickle uses different protocols to convert your data to a binary stream.

• In python 2 there are 3 different protocols (0, 1, 2) and the default is 0.

• In python 3 there are 5 different protocols (0, 1, 2, 3, 4) and the default is 3.

You must specify in python 3 a protocol lower than 3 in order to be able to load the data in python 2. You can specify the protocol parameter when invoking pickle.dump.

The xmlhttp request method is not valid for the files on local disk because the browser security does not allow us to do so.But we can override the browser security by creating a shortcut->right click->properties In target "... browser location path.exe" append --allow-file-access-from-files.This is tested on chrome,however care should be taken that all browser windows should be closed and the code should be run from the browser opened via this shortcut.

If you want to convert string to double data type then most choose parseDouble() method. See the example code:

String str = "123.67";
double d = parseDouble(str);

You will get the value in double. See the StringToDouble tutorial at tutorialData.

Add following command in Dockerfile:

RUN apt-get update

TL;DR:

In simple words, bind creates the function, call and apply executes the function whereas apply expects the parameters in array

Full Explanation

Assume we have multiplication function

function multiplication(a,b){
console.log(a*b);
}

Lets create some standard functions using bind

var multiby2 = multiplication.bind(this,2);

Now multiby2(b) is equal to multiplication(2,b);

multiby2(3); //6
multiby2(4); //8

What if I pass both the parameters in bind

var getSixAlways = multiplication.bind(this,3,2);

Now getSixAlways() is equal to multiplication(3,2);

getSixAlways();//6

even passing parameter returns 6; getSixAlways(12); //6

var magicMultiplication = multiplication.bind(this);

This create a new multiplication function and assigns it to magicMultiplication.

Oh no, we are hiding the multiplication functionality into magicMultiplication.

calling magicMultiplication returns a blank function b()

on execution it works fine magicMultiplication(6,5); //30

How about call and apply?

magicMultiplication.call(this,3,2); //6

magicMultiplication.apply(this,[5,2]); //10

Here's a function I wrote based on what sth's comment. It's works the same as json.dumps with indent, but I'm using tabs instead of space for indents. In Python 3.2+ you can specify indent to be a '\t' directly, but not in 2.7.

def pretty_dict(d):
    def pretty(d, indent):
        for i, (key, value) in enumerate(d.iteritems()):
            if isinstance(value, dict):
                print '{0}"{1}": {{'.format( '\t' * indent, str(key))
                pretty(value, indent+1)
                if i == len(d)-1:
                    print '{0}}}'.format( '\t' * indent)
                else:
                    print '{0}}},'.format( '\t' * indent)
            else:
                if i == len(d)-1:
                    print '{0}"{1}": "{2}"'.format( '\t' * indent, str(key), value)
                else:
                    print '{0}"{1}": "{2}",'.format( '\t' * indent, str(key), value)
    print '{'
    pretty(d,indent=1)
    print '}'

Ex:

>>> dict_var = {'a':2, 'b':{'x':3, 'y':{'t1': 4, 't2':5}}}
>>> pretty_dict(dict_var)
{
    "a": "2",
    "b": {
        "y": {
            "t2": "5",
            "t1": "4"
        },
        "x": "3"
    }
}

Use the package "recommenderlab". Download and install the package. This package has a command "Normalize" in built. It also allows you to choose one of the many methods for normalization namely 'center' or 'Z-score' Follow the following example:

## create a matrix with ratings
m <- matrix(sample(c(NA,0:5),50, replace=TRUE, prob=c(.5,rep(.5/6,6))),nrow=5, ncol=10, dimnames = list(users=paste('u', 1:5, sep=&rdquo;), items=paste('i', 1:10, sep=&rdquo;)))

## do normalization
r <- as(m, "realRatingMatrix")
#here, 'centre' is the default method
r_n1 <- normalize(r) 
#here "Z-score" is the used method used
r_n2 <- normalize(r, method="Z-score")

r
r_n1
r_n2

## show normalized data
image(r, main="Raw Data")
image(r_n1, main="Centered")
image(r_n2, main="Z-Score Normalization")

Default behaviour of PowerShell is just to dump everything that falls out of a pipeline without being picked up by another pipeline element or being assigned to a variable (or redirected) into Out-Host. What Out-Host does is obviously host-dependent.

Just letting things fall out of the pipeline is not a substitute for Write-Host which exists for the sole reason of outputting text in the host application.

If you want output, then use the Write-* cmdlets. If you want return values from a function, then just dump the objects there without any cmdlet.

The first thing you should try is:

sudo pip uninstall pip

On many environments that doesn't work. So given the lack of info on that problem, I ended up removing pip manually from /usr/local/bin.

Difference between split and partition is split returns the list without delimiter and will split where ever it gets delimiter in string i.e.

x = 'http://test.com/lalala-134-431'

a,b,c = x.split(-)
print(a)
"http://test.com/lalala"
print(b)
"134"
print(c)
"431"

and partition will divide the string with only first delimiter and will only return 3 values in list

x = 'http://test.com/lalala-134-431'
a,b,c = x.partition('-')
print(a)
"http://test.com/lalala"
print(b)
"-"
print(c)
"134-431"

so as you want last value you can use rpartition it works in same way but it will find delimiter from end of string

x = 'http://test.com/lalala-134-431'
a,b,c = x.partition('-')
print(a)
"http://test.com/lalala-134"
print(b)
"-"
print(c)
"431"

Unit Test - testing an individual unit, such as a method (function) in a class, with all dependencies mocked up.

Functional Test - AKA Integration Test, testing a slice of functionality in a system. This will test many methods and may interact with dependencies like Databases or Web Services.

They have estabilished their own set of rules how to comunicate when the time comes. He stands in her garden and throws the small rock at her window. Lisa knows that it is time, and responds by waving from the window and opening it afterwards so Mark can climb in. That was example how the API works. The rock is initial request to another end. Another end waves, opens the window which basicaly means "Welcome in!".

API is almost like human language but for computers.

Try:

var myMappings = {
    "Name":     "10%",
    "Phone":    "10%",
    "Address":  "50%",
    "Zip":      "10%",
    "Comments": "20%"
}

// Access is like this
myMappings["Name"] // Returns "10%"
myMappings.Name // The same thing as above

// To loop through...
for(var title in myMappings) {
    // Do whatever with myMappings[title]
}

Here is an example showing some text in circles with data from a json file: http://bl.ocks.org/4474971. Which gives the following:

The main idea behind this is to encapsulate the text and the circle in the same "div" as you would do in html to have the logo and the name of the company in the same div in a page header.

The main code is:

var width = 960,
    height = 500;

var svg = d3.select("body").append("svg")
    .attr("width", width)
    .attr("height", height)

d3.json("data.json", function(json) {
    /* Define the data for the circles */
    var elem = svg.selectAll("g")
        .data(json.nodes)

    /*Create and place the "blocks" containing the circle and the text */  
    var elemEnter = elem.enter()
        .append("g")
        .attr("transform", function(d){return "translate("+d.x+",80)"})

    /*Create the circle for each block */
    var circle = elemEnter.append("circle")
        .attr("r", function(d){return d.r} )
        .attr("stroke","black")
        .attr("fill", "white")

    /* Create the text for each block */
    elemEnter.append("text")
        .attr("dx", function(d){return -20})
        .text(function(d){return d.label})
})

and the json file is:

{"nodes":[
  {"x":80, "r":40, "label":"Node 1"}, 
  {"x":200, "r":60, "label":"Node 2"}, 
  {"x":380, "r":80, "label":"Node 3"}
]}

The resulting html code shows the encapsulation you want:

<svg width="960" height="500">
    <g transform="translate(80,80)">
        <circle r="40" stroke="black" fill="white"></circle>
        <text dx="-20">Node 1</text>
    </g>
    <g transform="translate(200,80)">
        <circle r="60" stroke="black" fill="white"></circle>
        <text dx="-20">Node 2</text>
    </g>
    <g transform="translate(380,80)">
        <circle r="80" stroke="black" fill="white"></circle>
        <text dx="-20">Node 3</text>
    </g>
</svg>

TLDR

This method does not require setuptools, path hacks, additional command line arguments, or specifying the top level of the package in every single file of your project.

Just make a script in the parent directory of whatever your are calling to be your __main__ and run everything from there. For further explanation continue reading.

Explanation

This can be accomplished without hacking a new path together, extra command line args, or adding code to each of your programs to recognize its siblings.

The reason this fails as I believe was mentioned before is the programs being called have their __name__ set as __main__. When this occurs the script being called accepts itself to be on the top level of the package and refuses to recognize scripts in sibling directories.

However, everything under the top level of the directory will still recognize ANYTHING ELSE under the top level. This means the ONLY thing you have to do to get files in sibling directories to recognize/utilize each other is to call them from a script in their parent directory.

Proof of Concept In a dir with the following structure:

.
|__Main.py
|
|__Siblings
   |
   |___sib1
   |   |
   |   |__call.py
   |
   |___sib2
       |
       |__callsib.py

Main.py contains the following code:

import sib1.call as call


def main():
    call.Call()


if __name__ == '__main__':
    main()

sib1/call.py contains:

import sib2.callsib as callsib


def Call():
    callsib.CallSib()


if __name__ == '__main__':
    Call()

and sib2/callsib.py contains:

def CallSib():
    print("Got Called")

if __name__ == '__main__':
    CallSib()

If you reproduce this example you will notice that calling Main.py will result in "Got Called" being printed as is defined in sib2/callsib.py even though sib2/callsib.py got called through sib1/call.py. However if one were to directly call sib1/call.py (after making appropriate changes to the imports) it throws an exception. Even though it worked when called by the script in its parent directory, it will not work if it believes itself to be on the top level of the package.

The methodNotAllowed exception indicates that a route doesn't exist for the HTTP method you are requesting.

Your form is set up to make a DELETE request, so your route needs to use Route::delete() to receive this.

Route::delete('empresas/eliminar/{id}', [
        'as' => 'companiesDelete',
        'uses' => 'CompaniesController@delete'
]);

MySQL date format is this : Y-M-D. You are using Y/M/D. That's is wrong. modify your query.

If you insert the date like Y/M/D, It will be insert null value in the database.

If you are using PHP and date you are getting from the form is like this Y/M/D, you can replace this with using the statement .

out_date=date('Y-m-d', strtotime(str_replace('/', '-', $data["input_date"])))

fmt.SprintF function returns a string and you can format the string the very same way you would have with fmt.PrintF

For Bootstrap 4, there are now spacing utilities so it's easier to change the height via padding on the nav links. This can be responsively applied only at specific breakpoints (ie: py-md-3). For example, on larger (md) screens, this nav is 120px high, then shrinks to normal height for the mobile menu. No extra CSS is needed..

<nav class="navbar navbar-fixed-top navbar-inverse bg-primary navbar-toggleable-md py-md-3">
    <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNav" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>
    <a class="navbar-brand" href="#">Brand</a>
    <div class="navbar-collapse collapse" id="navbarNav">
        <ul class="navbar-nav">
            <li class="nav-item py-md-3"><a href="#" class="nav-link">Home</a></li>
            <li class="nav-item py-md-3"><a href="#" class="nav-link">Link</a></li>
            <li class="nav-item py-md-3"><a href="#" class="nav-link">Link</a></li>
            <li class="nav-item py-md-3"><a href="#" class="nav-link">More</a></li>
            <li class="nav-item py-md-3"><a href="#" class="nav-link">Options</a></li>
        </ul>
    </div>
</nav>

Make sure that git is installed on your system. I'm explaining the process using windows OS

Here is how I did :

1.Open the cmd (you can do with git bash as well).

2.Go to your project directory(where your project is located).

3.Now type your_directory >git init this will initialize an empty repository if it is first time and enter. for eg :C:\Users>git init

4.Now type your_directory >git add <filename>(if specific files) or git add . (if you want to add all files) and enter.

5.Now type >git commit -m "commit message goes here" and enter.

(in case if you need to check the status you can do by typing >git status) and enter.

6.Now type >git remote add origin git_repository_url

(check>git remote -v) and enter.

7.Now turn to push it ...>git push origin master and enter

(if you get error you push it forcefully by typing ...>git push -f origin master and enter.

Now you're done with adding it to your repository. Refresh it and it will be there in your created repository.

Hopefully, this will work for you.

You also need to define PHPIniDir - c:/php_install_path

Try:

$('li.current_sub').prevAll("li.par_cat:first");

Tested it with your markup:

$('li.current_sub').prevAll("li.par_cat:first").text("woohoo");

will fill up the closest previous li.par_cat with "woohoo".

Note that list and array are different classes. You can do:

del mylist[:]

This will actually modify your existing list. David's answer creates a new list and assigns it to the same variable. Which you want depends on the situation (e.g. does any other variable have a reference to the same list?).

Try:

a = [1,2]
b = a
a = []

and

a = [1,2]
b = a
del a[:]

Print a and b each time to see the difference.

For bootstrap 3 datepicker. (Note the capital letters)

$("#datetimepicker").datetimepicker( {
  format: "YYYY",
  viewMode: "years"
});

This could be handled perhaps in a simpler way by using callback refs.

React allows you to pass a function into a ref, which returns the underlying DOM element or component node. See: https://reactjs.org/docs/refs-and-the-dom.html#callback-refs

const MyComponent = () => {
    const myRef = node => console.log(node ? node.innerText : 'NULL!');
    return <div ref={myRef}>Hello World</div>;
 }

This function gets fired whenever the underlying node is changed. It will be null in-between updates, so we need to check for this. Example:

const MyComponent = () => {
    const [time, setTime] = React.useState(123);
    const myRef = node => console.log(node ? node.innerText : 'NULL!');
    setTimeout(() => setTime(time+1), 1000);
    return <div ref={myRef}>Hello World {time}</div>;
}
/*** Console output: 
 Hello World 123
 NULL!
 Hello World 124
 NULL!
...etc
***/

While this does't handle resizing as such (we would still need a resize listener to handle the user resizing the window) I'm not sure that is what the OP was asking for. And this version will handle the node resizing due to an update.

So here is a custom hook based on this idea:

export const useClientRect = () => {
    const [rect, setRect] = useState({width:0, height:0});
    const ref = useCallback(node => {
        if (node !== null) {
            const { width, height } = node.getBoundingClientRect();
            setRect({ width, height });
        }
    }, []);
    return [rect, ref];
};

The above is based on https://reactjs.org/docs/hooks-faq.html#how-can-i-measure-a-dom-node

Note the hook returns a ref callback, instead of being passed a ref. And we employ useCallback to avoid re-creating a new ref function each time; not vital, but considered good practice.

Usage is like this (based on Marco Antônio's example):

const MyComponent = ({children}) => {
  const [rect, myRef] = useClientRect();
  const { width, height } = rect;

  return (
    <div ref={myRef}>
      <p>width: {width}px</p>
      <p>height: {height}px</p>
      {children}
    <div/>
  )
}

In my case this was caused by an integer overflow. I had a UInt16, and was doubling the value to put into an Int. The faulty code was

let result = Int(myUInt16 * 2)

However, this multiplies as a UInt16, then converts to Int. So if myUInt16 contains a value over 32767 then an overflow occurs.

All was well once I corrected the code to

let result = Int(myUint16) * 2

command `< file`

will pass file contents to the command on stdin, but will strip newlines, meaning you couldn't iterate over each line individually. For that you could write a script with a 'for' loop:

for line in `cat input_file`; do some_command "$line"; done

Or (the multi-line variant):

for line in `cat input_file`
do
    some_command "$line"
done

Or (multi-line variant with $() instead of ``):

for line in $(cat input_file)
do
    some_command "$line"
done

Have to join the fun...

    private void TestBench()
    {
        // An object to test
        string[] stringEnumerable = new string[] { "Easy", "as", "Pi" };

        ObjectListFromUnknown(stringEnumerable);
    }

    private void ObjectListFromUnknown(object o)
    {
        if (typeof(IEnumerable<object>).IsAssignableFrom(o.GetType()))
        {
            List<object> listO = ((IEnumerable<object>)o).ToList();
            // Test it
            foreach (var v in listO)
            {
                Console.WriteLine(v);
            }
        }
    }

As Paddy mentioned: if you use an overload of UrlHelper.Action() that explicitly specifies the protocol to use, the generated URL will be absolute and fully qualified instead of being relative.

I wrote a blog post called How to build absolute action URLs using the UrlHelper class in which I suggest to write a custom extension method for the sake of readability:

/// <summary>
/// Generates a fully qualified URL to an action method by using
/// the specified action name, controller name and route values.
/// </summary>
/// <param name="url">The URL helper.</param>
/// <param name="actionName">The name of the action method.</param>
/// <param name="controllerName">The name of the controller.</param>
/// <param name="routeValues">The route values.</param>
/// <returns>The absolute URL.</returns>
public static string AbsoluteAction(this UrlHelper url,
    string actionName, string controllerName, object routeValues = null)
{
    string scheme = url.RequestContext.HttpContext.Request.Url.Scheme;

    return url.Action(actionName, controllerName, routeValues, scheme);
}

You can then simply use it like that in your view:

@Url.AbsoluteAction("Action", "Controller")

Try to use the empty() function:

<xsl:if test="empty(node/ABC/node()) and empty(node/DEF/node())">
    <xsl:text>This should work</xsl:text>
</xsl:if>

This identifies ABC and DEF as empty in the sense that they do not have any child nodes (no elements, no text nodes, no processing instructions, no comments).

But, as pointed out by @Ian, your elements might not be empty really or that might not be your actual problem - you did not show what your input XML looks like.

Another cause of error could be your relative position in the tree. This way of testing conditions only works if the surrounding template matches the parent element of node or if you iterate over the parent element of node.

a possible solution in js

In case the WebSocket server initiative disconnects the ws link after a few minutes there no messages sent between the server and client.

1. client sends a custom ping message, to keep alive by using the keepAlive function

2. server ignore the ping message and response a custom pong message

var timerID = 0; 
function keepAlive() { 
    var timeout = 20000;  
    if (webSocket.readyState == webSocket.OPEN) {  
        webSocket.send('');  
    }  
    timerId = setTimeout(keepAlive, timeout);  
}  
function cancelKeepAlive() {  
    if (timerId) {  
        clearTimeout(timerId);  
    }  
}

That is because you have continuous text, means single long word without space. To break it add word-break: break-all;

.submenu div p {
    color:#fff;
    margin: 0;
    padding:0;
    width:100%;
    position: relative; word-break: break-all; background:red
}

I'd just use a simple regex, you can do something like this

import re
old_list = ['abc123', 'def456', 'ghi789']
new_list = [x for x in old_list if re.search('abc', x)]
for item in new_list:
    print item

I could do that following the steps:

1. Create a folder __mocks__/ (as pointed by @Januartha comment)
2. Implement an axios.js mock file
3. Use my implemented module on test

The mock will happen automatically

Example of the mock module:

module.exports = {
    get: jest.fn((url) => {
        if (url === '/something') {
            return Promise.resolve({
                data: 'data'
            });
        }
    }),
    post: jest.fn((url) => {
        if (url === '/something') {
            return Promise.resolve({
                data: 'data'
            });
        }
        if (url === '/something2') {
            return Promise.resolve({
                data: 'data2'
            });
        }
    }),
    create: jest.fn(function () {
        return this;
    })
};

^[^<>]+$

The caret in the character class ([^) means match anything but, so this means, beginning of string, then one or more of anything except < and >, then the end of the string.

Try to use this

parseFloat().toFixed(2)

Yes using Option Explicit is a good habit. Using .Select however is not :) it reduces the speed of the code. Also fully justify sheet names else the code will always run for the Activesheet which might not be what you actually wanted.

Is this what you are trying?

Option Explicit

Sub Sample()
    Dim lastRow As Long, i As Long
    Dim CopyRange As Range

    '~~> Change Sheet1 to relevant sheet name
    With Sheets("Sheet1")
        lastRow = .Range("A" & .Rows.Count).End(xlUp).Row

        For i = 2 To lastRow
            If Len(Trim(.Range("A" & i).Value)) <> 0 Then
                If CopyRange Is Nothing Then
                    Set CopyRange = .Rows(i)
                Else
                    Set CopyRange = Union(CopyRange, .Rows(i))
                End If
            Else
                Exit For
            End If
        Next

        If Not CopyRange Is Nothing Then
            '~~> Change Sheet2 to relevant sheet name
            CopyRange.Copy Sheets("Sheet2").Rows(1)
        End If
    End With
End Sub

NOTE

If if you have data from Row 2 till Row 10 and row 11 is blank and then you have data again from Row 12 then the above code will only copy data from Row 2 till Row 10

If you want to copy all rows which have data then use this code.

Option Explicit

Sub Sample()
    Dim lastRow As Long, i As Long
    Dim CopyRange As Range

    '~~> Change Sheet1 to relevant sheet name
    With Sheets("Sheet1")
        lastRow = .Range("A" & .Rows.Count).End(xlUp).Row

        For i = 2 To lastRow
            If Len(Trim(.Range("A" & i).Value)) <> 0 Then
                If CopyRange Is Nothing Then
                    Set CopyRange = .Rows(i)
                Else
                    Set CopyRange = Union(CopyRange, .Rows(i))
                End If
            End If
        Next

        If Not CopyRange Is Nothing Then
            '~~> Change Sheet2 to relevant sheet name
            CopyRange.Copy Sheets("Sheet2").Rows(1)
        End If
    End With
End Sub

Hope this is what you wanted?

I hope you are doing well.it often happens with all when they want to add new functionality in your app then normally they all search for libraries which are not good tactic because you don`t know what kind of code is in that libabry. so I always prefer to fork the libraries and add the useful classes and methods in my application code.

so when I stuck with the same issue, I make lots of much R&D then I find a class which gives the ability to zoomIn ,zoomOut and pinIn and out. so you can see that class here..

so as I told before, it is a single class. so you can put this class anywhere in your projects like utils folder.and put below lines into your XML files like:

<your_packege_name.TouchImageView
        android:id="@+id/frag_imageview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="fitCenter"
        android:src="@drawable/default_flag"
        android:transitionName="@string/transition_name_phone" /> 

and you can find that image view in your respected activity, as you did for all views like -:

TouchImageView tv=(TouchImageView)findViewById(R.id.frag_imageview); 
tv.setImageResource(R.drawable.ic_play);

that's it for TouchImageView. enjoy our code :)

Here is how we fixed this.

Step 1: Open Keychain access, delete "Apple world wide Developer relations certification authority" (which expires on 14th Feb 2016) from both "Login" and "System" sections. If you can't find it, use “Show Expired Certificates” in the View menu.

Step 2: Download this and add it to Keychain access -> Certificates (which expires on 8th Feb 2023).

Step 3: Everything should be back to normal and working now.

The DateTime class takes a string in the constructor. If you prefix the timestamp with a @-character you create a DateTime object with the timestamp. For formating use the 'c' format ... a predefined ISO 8601 compound format.

If could use the DateTime class like this ... set the right timezone or leave it out if you want a UTC time.

$dt = new DateTime('@1333699439');
$dt->setTimezone(new DateTimeZone('America/New_York'));
echo $dt->format('c');

For some reason my web.config had 0.0.0.0 in the oldVersion attribute:

        <bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="5.2.3.0" />
      </dependentAssembly>

changing to 1.0.0.0 was the solution:

    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35"/>
    <bindingRedirect oldVersion="1.0.0.0-5.2.3.0" newVersion="5.2.3.0"/>

The XML is most probably invalid.

The problem could be the "&"

$text=preg_replace('/&(?!#?[a-z0-9]+;)/', '&', $text);

will get rid of the "&" and replace it with it's HTML code version...give it a try.

At first check the file address, it must be beside your .java file or in any address that you define in classpath environment variable. When you check this then try below.

1. you must use a file name by it's extension in File object constructor, as an example:

   File myFile = new File("test.txt");

2. but there is a better way to use it inside Scanner object by pass the filename absolute address, as an example:

   Scanner sc = new Scanner(Paths.get("test.txt"));

in this way you must import java.nio.file.Paths as well.

Matthew's answer awoke many emotions, because of the fact that it still lacks a minor detail. The general command would be:

# yum --nogpgcheck localinstall <package1_file_name> ... <packageN_file_name>

The package_file_name above can include local absolute or relative path, or be a URL (possibly even an URI).

Yum would search for dependencies among all package files given on the command line AND IF IT FAILS to find the dependencies there, it will also use any configured and enabled yum repositories.

Neither the current working directory, nor the paths of any of package_file_name will be searched, except when any of these directories has been previously configured as an enabled yum repository.

So in the OP's case the yum command:

# cd <path with pkg files>; yum --nogpgcheck localinstall ./proj1-1.0-1.x86_64.rpm ./libtest1-1.0-1.x86_64.rpm

would do, as would do the rpm:

# cd <path with pkg files>; rpm -i proj1-1.0-1.x86_64.rpm libtest1-1.0-1.x86_64.rpm

The differencve between these yum and rpm invocations would only be visible if one of the packages listed to be installed had further dependencies on packages NOT listed on the command line.

In such a case rpm will just refuse to continue, while yum would use any configured and enabled yum repositories to search for dependencies, and may possibly succeed.

The current working directory will NOT be searched in any case, except when it has been previously configured as an enabled yum repository.

Referring to man page man mkdir for option -p

   -p, --parents
          no error if existing, make parent directories as needed

which will create all directories in a given path, if exists throws no error otherwise it creates all directories from left to right in the given path. Try the below command. the directories newdir and anotherdir doesn't exists before issuing this command

Correct Usage

mkdir -p /tmp/newdir/anotherdir

After executing the command you can see newdir and anotherdir created under /tmp. You can issue this command as many times you want, the command always have exit(0). Due to this reason most people use this command in shell scripts before using those actual paths.

A late answer, but and approach using data.table

library(data.table)
DT <- data.table(dat)

DT[, .SD[which.max(Score),], by = Group]

Or, if it is possible to have more than one equally highest score

DT[, .SD[which(Score == max(Score)),], by = Group]

Noting that (from ?data.table

.SD is a data.table containing the Subset of x's Data for each group, excluding the group column(s)

G45,

I faced same issue , i have created one directive , please check below hope it may be helpful

Directive :

    app.directive('formSubmitValidation', function () {

        return {
            require: 'form',
            compile: function (tElem, tAttr) {

                tElem.data('augmented', true);

                return function (scope, elem, attr, form) {
                    elem.on('submit', function ($event) {
                        scope.$broadcast('form:submit', form);

                        if (!form.$valid) {
                            $event.preventDefault();
                        }
                        scope.$apply(function () {
                            scope.submitted = true;
                        });


                    });
                }
            }
        };


  })

HTML :

<form  name="loginForm" class="c-form-login" action="" method="POST" novalidate="novalidate" form-submit-validation="">

<div class="form-group">
                                                <input type="email" class="form-control c-square c-theme input-lg" placeholder="Email" ng-model="_username" name="_username" required>
                                                <span class="glyphicon glyphicon-user form-control-feedback c-font-grey"></span>
                                                <span ng-show="submitted || loginForm._username.$dirty && loginForm._username.$invalid">
                                                    <span ng-show="loginForm._username.$invalid" class="error">Please enter a valid email.</span>
                                                </span>
                                            </div>
<button type="submit" class="pull-right btn btn-lg c-theme-btn c-btn-square c-btn-uppercase c-btn-bold">Login</button>
</form>

Wikipedia has a great section on the differences between Semaphores and Mutexes:

A mutex is essentially the same thing as a binary semaphore and sometimes uses the same basic implementation. The differences between them are:

Mutexes have a concept of an owner, which is the process that locked the mutex. Only the process that locked the mutex can unlock it. In contrast, a semaphore has no concept of an owner. Any process can unlock a semaphore.

Unlike semaphores, mutexes provide priority inversion safety. Since the mutex knows its current owner, it is possible to promote the priority of the owner whenever a higher-priority task starts waiting on the mutex.

Mutexes also provide deletion safety, where the process holding the mutex cannot be accidentally deleted. Semaphores do not provide this.

Here is an easy way:

Response.Write("<script>alert('Hello');</script>");
