Programs & Examples On #Xmpphp

Some x86 instructions are designed to leave the content of the operands (registers) as they are and just set/unset specific internal CPU flags like the zero-flag (ZF). You can think at the ZF as a true/false boolean flag that resides inside the CPU.

in this particular case, TEST instruction performs a bitwise logical AND, discards the actual result and sets/unsets the ZF according to the result of the logical and: if the result is zero it sets ZF = 1, otherwise it sets ZF = 0.

Conditional jump instructions like JE are designed to look at the ZF for jumping/notjumping so using TEST and JE together is equivalent to perform a conditional jump based on the value of a specific register:

example:

TEST EAX,EAX
JE some_address

the CPU will jump to "some_address" if and only if ZF = 1, in other words if and only if AND(EAX,EAX) = 0 which in turn it can occur if and only if EAX == 0

the equivalent C code is:

if(eax == 0)
{
    goto some_address
}

With JUnit 4.12 the following didn't work for me:

java -cp .:/usr/share/java/junit.jar org.junit.runner.JUnitCore [test class name]

Apparently, from JUnit 4.11 onwards you should also include hamcrest-core.jar in your classpath:

java -cp .:/usr/share/java/junit.jar:/usr/share/java/hamcrest-core.jar org.junit.runner.JUnitCore [test class name]

I also agree with the OP that all these things should come with Python already set. I guess we will have to deal with it until that day comes. Here is a solution that actually worked for me :

installing easy_install faster and easier

I hope it helps you or anyone with the same problem!

You'll want to install the sshpass program. Then:

sshpass -p YOUR_PASSWORD sftp -oBatchMode=no -b YOUR_COMMAND_FILE_PATH USER@HOST

Obviously, it's better to setup public key authentication. Only use this if that's impossible to do, for whatever reason.

File Word-Count

If in between words having some symbols then you can split and count the number of Words.

Scanner sc = new Scanner(new FileInputStream(new File("Input.txt")));
        int count = 0;
        while (sc.hasNext()) {

            String[] s = sc.next().split("d*[.@:=#-]"); 

            for (int i = 0; i < s.length; i++) {
                if (!s[i].isEmpty()){
                    System.out.println(s[i]);
                    count++;
                }   
            }           
        }
        System.out.println("Word-Count : "+count);

You can pass an object which is refering to all the values at a particular index.

import java.util.ArrayList;

public class HelloWorld{

 public static void main(String []args){


ArrayList<connect> a=new ArrayList<connect>();

a.add(new connect(100,100,100,100,100));

System.out.println(a.get(0).p1);

System.out.println(a.get(0).p2);

System.out.println(a.get(0).p3);
}

}

class connect
{
int p1,p2,p3,p4,p5;

connect(int a,int b,int c,int d,int e)
{

this.p1=a;

this.p2=b;

this.p3=c;

this.p4=d;

this.p5=e;
}

}

Later to get a particular value at a specific index, you can do this:

a.get(0).p1;

a.get(0).p2;

a.get(0).p3;.............

and so on.

Did you try

string.trim(); 

This is meant to trim all leading and leaning while spaces in the string. Hope this helps.

Edit: (I was not explicit enough)

So, when you string.split(), you will have a string[] - for each of the strings in the array, do a string.trim() and then append it.

String[] tokens = yourString.split(" ");
StringBuffer buff = new StringBuffer();
for (String token : tokens)
{
  buff.append(token.trim());
}

Use stringBuffer/Builder instead of appending in the same string.

By simplified sequence :

mydata[-(1:3 * 2), ]

By sequence :

mydata[seq(1, nrow(mydata), by = 2) , ]

By negative sequence :

mydata[-seq(2, nrow(mydata), by = 2) , ]

Or if you want to subset by selecting odd numbers:

mydata[which(1:nrow(mydata) %% 2 == 1) , ]

Or if you want to subset by selecting odd numbers, version 2:

mydata[which(1:nrow(mydata) %% 2 != 0) , ]

Or if you want to subset by filtering even numbers out:

mydata[!which(1:nrow(mydata) %% 2 == 0) , ]

Or if you want to subset by filtering even numbers out, version 2:

mydata[!which(1:nrow(mydata) %% 2 != 1) , ]

you can use this as well

function getParameterByName(name) {
    name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
    var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
        results = regex.exec(location.search);
    return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}

var queryValue = getParameterByName('test_user_bLzgB');

Apparently this will not work for negative values, but it will for positive numbers.

Use isdigit()

if userinput.isdigit():
    #do stuff

Here's a very pragmatic idiom:

(cd $dir) || return # Is this a directory,
                    # and do we have access?

I typically wrap it in a function:

can_use_as_dir() {
    (cd ${1:?pathname expected}) || return
}

Or:

assert_dir_access() {
    (cd ${1:?pathname expected}) || exit
}

The nice thing about this approach is that I do not have to think of a good error message.

cd will give me a standard one line message to standard error already. It will also give more information than I will be able to provide. By performing the cd inside a subshell ( ... ), the command does not affect the current directory of the caller. If the directory exists, this subshell and the function are just a no-op.

Next is the argument that we pass to cd: ${1:?pathname expected}. This is a more elaborate form of parameter substitution which is explained in more detail below.

Tl;dr: If the string passed into this function is empty, we again exit from the subshell ( ... ) and return from the function with the given error message.

Quoting from the ksh93 man page:

${parameter:?word}

If parameter is set and is non-null then substitute its value; otherwise, print word and exit from the shell (if not interactive). If word is omitted then a standard message is printed.

and

If the colon : is omitted from the above expressions, then the shell only checks whether parameter is set or not.

The phrasing here is peculiar to the shell documentation, as word may refer to any reasonable string, including whitespace.

In this particular case, I know that the standard error message 1: parameter not set is not sufficient, so I zoom in on the type of value that we expect here - the pathname of a directory.

A philosophical note:

The shell is not an object oriented language, so the message says pathname, not directory. At this level, I'd rather keep it simple - the arguments to a function are just strings.

If the check box's ID "Delete" then for the "onclick" event of the submit button the javascript function can be as follows:

html:
<input type="checkbox" name="Delete" value="Delete" id="Delete"></td>
<input type="button" value="Delete" name="delBtn" id="delBtn" onclick="deleteData()">

script:
<script type="text/Javascript">
    function deleteData() {
        if(!document.getElementById('Delete').checked){
            alert('Checkbox not checked');
            return false;
        }
</script>

http://www.viemu.com/a-why-vi-vim.html is a good advocacy article. It explains the power of using the . command to repeat the last edit.

Copy/Cut & paste. I do it all the time. With all the classical editors you press Shift with the left hand, and you move the cursor with your right hand to select text. Then Ctrl+C copies, you move the cursor and Ctrl+V pastes.

With Vim it's horrible:

* yy to copy one line (you almost never want the whole line!)
* [number xx]yy to copy xx lines into the buffer. But you never know

exactly if you've selected what you wanted. I often have to do [number xx]dd then u to undo!

I'm sure the other answers have explained better, but You're Doing It Wrong. I often use visual mode to select text to yank or delete, which is similar to your shift + select example, but Vim has a clear advantage here because your hands never leave home row to do it. yy is a great command but I often do Vy instead if I want to yank a whole line.

You have to use RegExp:

str.match(new RegExp(pattern1+'|'+pattern2, 'gi'));

When I'm concatenating strings, all slashes are gone.

If you have a backslash in your pattern to escape a special regex character, (like \(), you have to use two backslashes in the string (because \ is the escape character in a string): new RegExp('\\(') would be the same as /\(/.

So your patterns have to become:

var pattern1 = ':\\(|:=\\(|:-\\(';
var pattern2 = ':\\(|:=\\(|:-\\(|:\\(|:=\\(|:-\\(';

Try this code. By using the parent>child selector "#productList li" it should find all li elements. Then, you can iterate through the result object using the each() method which will only alter li elements that have been found.

listItems = $("#productList li").each(function(){

        var product = $(this);
        var productid = product.children(".productId").val();
        var productPrice = product.find(".productPrice").val();
        var productMSRP = product.find(".productMSRP").val();

        totalItemsHidden.val(parseInt(totalItemsHidden.val(), 10) + 1);
        subtotalHidden.val(parseFloat(subtotalHidden.val()) + parseFloat(productMSRP));
        savingsHidden.val(parseFloat(savingsHidden.val()) + parseFloat(productMSRP - productPrice));
        totalHidden.val(parseFloat(totalHidden.val()) + parseFloat(productPrice));

    });

for a Map we have a list of elements and a (function,action) f so :

[a,b,c] f(x) => [f(a),f(b),f(c)]

and for the flat map we have a list of elements list and we have a (function,action) f and we want the result to be flattened :

[[a,b],[c,d,e]] f(x) =>[f(a),f(b),f(c),f(d),f(e)]

java.sql.Timestamp extends java.util.Date. You can do:

String s = new SimpleDateFormat("MM/dd/yyyy").format(myTimestamp);

Or to also include time:

String s = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss").format(myTimestamp);

It is highly unlikely that adding NameVirtualHost *:443 is the right solution, because there are a limited number of situations in which it is possible to support name-based virtual hosts over SSL. Read this and this for some details (there may be better docs out there; these were just ones I found that discuss the issue in detail).

If you're running a relatively stock Apache configuration, you probably have this somewhere:

<VirtualHost _default_:443>

Your best bet is to either:

• Place your additional SSL configuration into this existing VirtualHost container, or
• Comment out this entire VirtualHost block and create a new one. Don't forget to include all the relevant SSL options.

You can use this..

var asciiVal = "32343630".match(/.{1,2}/g).map(function(v){_x000D_
      return String.fromCharCode(parseInt(v, 16));_x000D_
    }).join('');_x000D_
    _x000D_
document.write(asciiVal);

you have to add the missing local lang helper: for me the missing ones where de_LU de_LU.UTF-8 . Mongo 2.6.4 worked wihtout mongo 2.6.5 throw an error on this

However, you should also read Elias Mårtenson's answer on Android plurals treatment of “zero”. There is a problem with the interpretation of certain values such as "zero".

Yes, you should use docstrings to make your classes and functions more friendly to other programmers:

More: http://www.python.org/dev/peps/pep-0257/#what-is-a-docstring

Some editors allow you to see docstrings while typing, so it really makes work easier.

How to update in codeignitor?

whenever you want to update same status with multiple rows you use where_in insteam of where or if you want to change only single record can use where.

below is my code

$conditionArray = array(1, 3, 4, 6);
$this->db->where_in("ip_id", $conditionArray);
$this->db->update($this->table, array("status" => 'active'));

its working perfect.

I tried accepted answer and got message saying generated excel file is corrupted when trying to open. I was able to fix it by doing few modifications like adding below line end of the code.

You can use DataContractJsonSerializer. See this link for more details.

hex_string = "".join("%02x" % b for b in array_alpha)

A (dirty) possible solution is by using patterns,

here is an example with an inside stroked triangle :

https://jsfiddle.net/qr3p7php/5/

<style>
#triangle1{
  fill: #0F0;
  fill-opacity: 0.3;
  stroke: #000;
  stroke-opacity: 0.5;
  stroke-width: 20;
}
#triangle2{
  stroke: #f00;
  stroke-opacity: 1;
  stroke-width: 1;
}    
</style>

<svg height="210" width="400" >
    <pattern id="fagl" patternUnits="objectBoundingBox" width="2" height="1" x="-50%">
        <path id="triangle1" d="M150 0 L75 200 L225 200 Z">
    </pattern>    
    <path id="triangle2" d="M150 0 L75 200 L225 200 Z" fill="url(#fagl)"/>
</svg>

You could try defining a new DecimalFormat and using it as a Double result to a new double variable.

Example given to make you understand what I just said.

double decimalnumber = 100.2397;
DecimalFormat dnf = new DecimalFormat( "#,###,###,##0.00" );
double roundednumber = new Double(dnf.format(decimalnumber)).doubleValue();

Using java 8 LocalDateTime and java 7 try-with statement:

public class WriteFile {

    public static void main(String[] args) {

        String timeLog = DateTimeFormatter.ofPattern("yyyyMMdd_HHmmss").format(LocalDateTime.now());
        File logFile = new File(timeLog);

        try (BufferedWriter bw = new BufferedWriter(new FileWriter(logFile))) 
        {
            System.out.println("File was written to: "  + logFile.getCanonicalPath());
            bw.write("Hello world!");
        } 
        catch (IOException e) 
        {
            e.printStackTrace();
        }
    }
}

When calling finish() on an activity, the method onDestroy() is executed. This method can do things like:

1. Dismiss any dialogs the activity was managing.
2. Close any cursors the activity was managing.
3. Close any open search dialog

Also, onDestroy() isn't a destructor. It doesn't actually destroy the object. It's just a method that's called based on a certain state. So your instance is still alive and very well* after the superclass's onDestroy() runs and returns.Android keeps processes around in case the user wants to restart the app, this makes the startup phase faster. The process will not be doing anything and if memory needs to be reclaimed, the process will be killed

^{This is a new answer to an old question about a common misconception about contains() in XPath...}

Summary: contains() means contains a substring, not contains a node.

Detailed Explanation

This XPath is often misinterpreted:

//ul[contains(li, 'Model')]

Wrong interpretation: Select those ul elements that contain an li element with Model in it.

This is wrong because

1. contains(x,y) expects x to be a string, and

2. the XPath rule for converting multiple elements to a string is this:

   A node-set is converted to a string by returning the string-value of the node in the node-set that is first in document order. If the node-set is empty, an empty string is returned.

Right interpretation: Select those ul elements whose first li child has a string-value that contains a Model substring.

Examples

XML

<r>
  <ul id="one">
    <li>Model A</li>
    <li>Foo</li>
  </ul>
  <ul id="two">
    <li>Foo</li>
    <li>Model A</li>
  </ul>
</r> 

XPaths

• //ul[contains(li, 'Model')] selects the one ul element.

  Note: The two ul element is not selected because the string-value of the first li child of the two ul is Foo, which does not contain the Model substring.

• //ul[li[contains(.,'Model')]] selects the one and two ul elements.

  Note: Both ul elements are selected because contains() is applied to each li individually. (Thus, the tricky multiple-element-to-string conversion rule is avoided.) Both ul elements do have an li child whose string value contains the Model substring -- position of the li element no longer matters.

AForge.net is a free (open-source) library with Fast Fourier Transform support. (See Sources/Imaging/ComplexImage.cs for usage, Sources/Math/FourierTransform.cs for implemenation)

myprocess.out & would run the process in background using a subshell. If the current shell is terminated (say by logout), all subshells are also terminated so the background process would also be terminated. The nohup command ignores the HUP signal and thus even if the current shell is terminated, the subshell and myprocess.out would continue to run in the background. Another difference is that & alone doesn't redirect the stdout/stderr so if there are any output or error, those are displayed on the terminal. nohup on the other hand redirect the stdout/stderr to nohup.out or $HOME/nohup.out.

Arrays are, in general, a poor data structure to use if you want to ask if a particular object is in the collection or not.

If you'll be running this search frequently, it might be worth it to use a Dictionary<string, something> rather than an array. Lookups in a Dictionary are O(1) (constant-time), while searching through the array is O(N) (takes time proportional to the length of the array).

Even if the array is only 200 items at most, if you do a lot of these searches, the Dictionary will likely be faster.

"Server not found in Kerberos database" error can happen if you have registered the SPN to multiple users/computers.

You can check that with:

$ SetSPN -Q ServicePrincipalName
( SetSPN -Q HTTP/my.server.local@MYDOMAIN )

Another option to consider is Zenity: http://freecode.com/projects/zenity.

I had a situation where I was developing a Python server application (no GUI component) and hence didn't want to introduce a dependency on any python GUI toolkits, but I wanted some of my debug scripts to be parameterized by input files and wanted to visually prompt the user for a file if they didn't specify one on the command line. Zenity was a perfect fit. To achieve this, invoke "zenity --file-selection" using the subprocess module and capture the stdout. Of course this solution isn't Python-specific.

Zenity supports multiple platforms and happened to already be installed on our dev servers so it facilitated our debugging/development without introducing an unwanted dependency.

You should be aware that [^a-zA-Z] will replace characters not being itself in the character range A-Z/a-z. That means special characters like é, ß etc. or cyrillic characters and such will be removed.

If the replacement of these characters is not wanted use pre-defined character classes instead:

 str.replaceAll("[^\\p{IsAlphabetic}\\p{IsDigit}]", "");

PS: \p{Alnum} does not achieve this effect, it acts the same as [A-Za-z0-9].

Everyone is posting such complicated answers.

I found an easy answer, for scrolling to the bottom, nicely:

final ScrollView myScroller = (ScrollView) findViewById(R.id.myScrollerView);

// Scroll views can only have 1 child, so get the first child's bottom,
// which should be the full size of the whole content inside the ScrollView
myScroller.smoothScrollTo( 0, myScroller.getChildAt( 0 ).getBottom() );

And, if necessary, you can put the second line of code, above, into a runnable:

myScroller.post( new Runnable() {
    @Override
    public void run() {
        myScroller.smoothScrollTo( 0, myScroller.getChildAt( 0 ).getBottom() );
    }
}

It took me much research and playing around to find this simple solution. I hope it helps you, too! :)

The problem is most probably between a . and a _. Say in my query I put

SELECT ..... FROM LOCATION.PT

instead of

SELECT ..... FROM LOCATION_PT

So I think MySQL would think LOCATION as a database name and was giving access privilege error.

file='test.xlsx'
if file.endswith('.csv'):
    print('file is CSV')
elif file.endswith('.xlsx'):
    print('file is excel')
else:
    print('none of them')

Not applicable in most circumstances, but I had lots of async scripts running in the browser and as a hack I do

window.reload();

to stop everything.

doAnswer and thenReturn do the same thing if:

1. You are using Mock, not Spy
2. The method you're stubbing is returning a value, not a void method.

Let's mock this BookService

public interface BookService {
    String getAuthor();
    void queryBookTitle(BookServiceCallback callback);
}

You can stub getAuthor() using doAnswer and thenReturn.

BookService service = mock(BookService.class);
when(service.getAuthor()).thenReturn("Joshua");
// or..
doAnswer(new Answer() {
    @Override
    public Object answer(InvocationOnMock invocation) throws Throwable {
        return "Joshua";
    }
}).when(service).getAuthor();

Note that when using doAnswer, you can't pass a method on when.

// Will throw UnfinishedStubbingException
doAnswer(invocation -> "Joshua").when(service.getAuthor());

So, when would you use doAnswer instead of thenReturn? I can think of two use cases:

1. When you want to "stub" void method.

Using doAnswer you can do some additionals actions upon method invocation. For example, trigger a callback on queryBookTitle.

BookServiceCallback callback = new BookServiceCallback() {
    @Override
    public void onSuccess(String bookTitle) {
        assertEquals("Effective Java", bookTitle);
    }
};
doAnswer(new Answer() {
    @Override
    public Object answer(InvocationOnMock invocation) throws Throwable {
        BookServiceCallback callback = (BookServiceCallback) invocation.getArguments()[0];
        callback.onSuccess("Effective Java");
        // return null because queryBookTitle is void
        return null;
    }
}).when(service).queryBookTitle(callback);
service.queryBookTitle(callback);

2. When you are using Spy instead of Mock

When using when-thenReturn on Spy Mockito will call real method and then stub your answer. This can cause a problem if you don't want to call real method, like in this sample:

List list = new LinkedList();
List spy = spy(list);
// Will throw java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
when(spy.get(0)).thenReturn("java");
assertEquals("java", spy.get(0));

Using doAnswer we can stub it safely.

List list = new LinkedList();
List spy = spy(list);
doAnswer(invocation -> "java").when(spy).get(0);
assertEquals("java", spy.get(0));

Actually, if you don't want to do additional actions upon method invocation, you can just use doReturn.

List list = new LinkedList();
List spy = spy(list);
doReturn("java").when(spy).get(0);
assertEquals("java", spy.get(0));

The getApplication() method is located in the Activity class, so whenever you want getApplication() in a non activity class you have to pass an Activity instance to the constructor of that non activity class.

assume that test is my non activity class:

Test test = new Test(this);

In that class i have created one constructor:

 public Class Test
 {
    public Activity activity;
    public Test (Activity act)
    {
         this.activity = act;
         // Now here you can get getApplication()
    }
 }

If you want to install a bunch of dependencies from, say a requirements.txt, you would do:

mkdir dependencies
pip download -r requirements.txt -d "./dependencies"
tar cvfz dependencies.tar.gz dependencies

And, once you transfer the dependencies.tar.gz to the machine which does not have internet you would do:

tar zxvf dependencies.tar.gz
cd dependencies
pip install * -f ./ --no-index

On Mac OS X and If you are using Postgres App (http://postgresapp.com/):

export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/latest/bin

No need to specify version of Postgres in this command. It will be always pointed to latest.

and do

pip install psycopg2

Convert your x-axis data from text to datetime.datetime, use datetime.strptime:

>>> from datetime import datetime
>>> datetime.strptime("2012-may-31 19:00", "%Y-%b-%d %H:%M")
 datetime.datetime(2012, 5, 31, 19, 0)

This is an example of how to plot data once you have an array of datetimes:

import matplotlib.pyplot as plt
import datetime
import numpy as np

x = np.array([datetime.datetime(2013, 9, 28, i, 0) for i in range(24)])
y = np.random.randint(100, size=x.shape)

plt.plot(x,y)
plt.show()

just isolate your data frame to the columns you need, then use the unique function :D

# in the above example, you only need the first three columns
deduped.data <- unique( yourdata[ , 1:3 ] )
# the fourth column no longer 'distinguishes' them, 
# so they're duplicates and thrown out.

You can edit a subset of a dataframe by using loc:

df.loc[<row selection>, <column selection>]

In this case:

w.loc[w.female != 'female', 'female'] = 0
w.loc[w.female == 'female', 'female'] = 1

SELECT * FROM TABLENAME WHERE FIND_IN_SET(@search, column)

If it turns out your column has whitespaces in between the list items, use

SELECT * FROM TABLENAME WHERE FIND_IN_SET(@search, REPLACE(column, ' ', ''))

And caught the Data in onMessageReceived

public class MyFirebaseMessagingService extends FirebaseMessagingService     {

  private static final String TAG = "MyFirebaseMsgService";

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    Log.d(TAG, "From: " + remoteMessage.getFrom());

      sendNotification(remoteMessage.getData().get("message"));
     }
   // Check if message contains a notification payload.
    else if (remoteMessage.getNotification() != null) {
        Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
    sendNotification(remoteMessage.getNotification().getBody());
    }


}
   private void sendNotification(String messageBody) {
    Intent intent = new Intent(this, Notify.class).putExtra("msg",messageBody);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

adb remount

works for me and seems to be the simplest solution.

Step 1 => Place your .htaccess file in root folder where application and system folders exist.

Step 2 => If your web path using sub-folder like - yourdomain.com/project/ - then use following code in htaccess file

RewriteEngine on
RewriteBase    /project/
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /project/index.php/$1 [L]

If your web path using root-folder like - yourdomain.com - then use following code in htaccess file

RewriteEngine on
RewriteBase    /
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]

Handlebars partials take a second parameter which becomes the context for the partial:

{{> person this}}

In versions v2.0.0 alpha and later, you can also pass a hash of named parameters:

{{> person headline='Headline'}}

You can see the tests for these scenarios: https://github.com/wycats/handlebars.js/blob/ce74c36118ffed1779889d97e6a2a1028ae61510/spec/qunit_spec.js#L456-L462 https://github.com/wycats/handlebars.js/blob/e290ec24f131f89ddf2c6aeb707a4884d41c3c6d/spec/partials.js#L26-L32

I solved this another way. Let's say you have your dependency.js

export const myFunction = () => { }

I create a depdency.mock.js file besides it with the following content:

export const mockFunction = jest.fn();

jest.mock('dependency.js', () => ({ myFunction: mockFunction }));

And in the test, before I import the file that has the dependency, I use:

import { mockFunction } from 'dependency.mock'
import functionThatCallsDep from './tested-code'

it('my test', () => {
    mockFunction.returnValue(false);

    functionThatCallsDep();

    expect(mockFunction).toHaveBeenCalled();

})

or Just %~F will give you the full path and full file name.

For example, if you want to register all *.ax files in the current directory....

FOR /R C:. %F in (*.ax) do regsvr32 "%~F"

This works quite nicely in Win7 (64bit) :-)

I prefer not to put source/Javadoc download settings into the project pom.xml file as I feel these are user preferences, not project properties. Instead, I place them in a profile in my settings.xml file:

I know I'm late on this one:

def convert_keys_to_string(dictionary):
    """Recursively converts dictionary keys to strings."""
    if not isinstance(dictionary, dict):
        return dictionary
    return dict((str(k), convert_keys_to_string(v)) 
        for k, v in dictionary.items())

Another option:

$(el).trigger({type: 'keypress', which: 13, keyCode: 13});

i recently experienced this issue when i was trying to build and suddenly the laptop battery ran out of charge. I just removed all the servers from eclipse and then restore it. after doing that, i re-built the war file and it worked.

I like to do it like old times. You just use a custom UITextField Class like this one:

//
//  ReadOnlyTextField.swift
//  MediFormulas
//
//  Created by Oscar Rodriguez on 6/21/17.
//  Copyright © 2017 Nica Code. All rights reserved.
//

import UIKit

class ReadOnlyTextField: UITextField {

    /*
    // Only override draw() if you perform custom drawing.
    // An empty implementation adversely affects performance during animation.
    override func draw(_ rect: CGRect) {
        // Drawing code
    }
    */

    override init(frame: CGRect) {
        super.init(frame: frame)

        // Avoid keyboard to show up
        self.inputView = UIView()
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)

        // Avoid keyboard to show up
        self.inputView = UIView()
    }

    override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
        // Avoid cut and paste option show up
        if (action == #selector(self.cut(_:))) {
            return false
        } else if (action == #selector(self.paste(_:))) {
            return false
        }

        return super.canPerformAction(action, withSender: sender)
    }

}

If you can create your sql statement dynamically you can do following workaround:

String myArray[][] = { { "1-1", "1-2" }, { "2-1", "2-2" }, { "3-1", "3-2" } };

StringBuffer mySql = new StringBuffer("insert into MyTable (col1, col2) values (?, ?)");

for (int i = 0; i < myArray.length - 1; i++) {
    mySql.append(", (?, ?)");
}

myStatement = myConnection.prepareStatement(mySql.toString());

for (int i = 0; i < myArray.length; i++) {
    myStatement.setString(i, myArray[i][1]);
    myStatement.setString(i, myArray[i][2]);
}
myStatement.executeUpdate();

Use the <button> tag instead. <button> labels are vertically centered by default.

What about -mmin?

find /var/www/html/audio -daystart -maxdepth 1 -mmin +59 -type f -name "*.mp3" \
    -exec rm -f {} \;

From man find:

-mmin n
        File's data was last modified n minutes ago.

Also, make sure to test this first!

... -exec echo rm -f '{}' \;
          ^^^^ Add the 'echo' so you just see the commands that are going to get
               run instead of actual trying them first.

I am on a 64 bit system, and I only got this to work after installing both the 32 and 64 bit versions of the redistributable. I did not try the 64 bit version by itself due to the other posters' warnings about using the 32 bit version (and am too lazy to uninstall the 32 bit version now that I have it working), so I don't know if the 32 bit version is needed or not in cases like mine.

You can just copy & paste these methods (Swift 4+):

    class func encryptMessage(message: String, encryptionKey: String, iv: String) -> String? {
        if let aes = try? AES(key: encryptionKey, iv: iv),
            let encrypted = try? aes.encrypt(Array<UInt8>(message.utf8)) {
            return encrypted.toHexString()
        }
        return nil
    }

    class func decryptMessage(encryptedMessage: String, encryptionKey: String, iv: String) -> String? {
        if let aes = try? AES(key: encryptionKey, iv: iv),
            let decrypted = try? aes.decrypt(Array<UInt8>(hex: encryptedMessage)) {
            return String(data: Data(bytes: decrypted), encoding: .utf8)
        }
        return nil
    }

Example:

let encryptMessage = encryptMessage(message: "Hello World!", encryptionKey: "mykeymykeymykey1", iv: "myivmyivmyivmyiv")    
// Output of encryptMessage is: 649849a5e700d540f72c4429498bf9f4

let decryptedMessage = decryptMessage(encryptedMessage: encryptMessage, encryptionKey: "mykeymykeymykey1", iv: "myivmyivmyivmyiv")
// Output of decryptedMessage is: Hello World!

Don't forget encryptionKey & iv should be 16 bytes.

Try this

public void onClick(View view){
    txtView.setText("hello");

    //printmyname();
    Toast.makeText(NameonbuttonclickActivity.this, "hello", Toast.LENGTH_LONG).show();
}

Also in toast use "Hello"

I found that the following worked better...

   private void EndResponse()
    {
        try
        {
            Context.Response.End();
        }
        catch (System.Threading.ThreadAbortException err)
        {
            System.Threading.Thread.ResetAbort();
        }
        catch (Exception err)
        {
        }
    }

You can install it by first extracting all the files from the ISO and then overwriting those files with the files from the ZIP. Then you can run the batch file as administrator to do the installation. Most of the packages install on windows 7, but I haven't tested yet how well they work.

In random.random() the output lies between 0 & 1 , and it takes no input parameters

Whereas random.uniform() takes parameters , wherein you can submit the range of the random number. e.g.
import random as ra print ra.random() print ra.uniform(5,10)

OUTPUT:-
0.672485369423 7.9237539416

This kind of thing happened to me when I was using php language construct exit; in middle of transaction. Then this transaction "hangs" and you need to kill mysql process (described above with processlist;)

You can receive returning results like that: AsyncTask class

@Override
protected Boolean doInBackground(Void... params) {
    if (host.isEmpty() || dbName.isEmpty() || user.isEmpty() || pass.isEmpty() || port.isEmpty()) {
        try {
            throw new SQLException("Database credentials missing");
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }

    try {
        Class.forName("org.postgresql.Driver");
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }

    try {
        this.conn = DriverManager.getConnection(this.host + ':' + this.port + '/' + this.dbName, this.user, this.pass);
    } catch (SQLException e) {
        e.printStackTrace();
    }

    return true;
}

receiving class:

_store.execute();
boolean result =_store.get();

Hoping it will help.

The problem was that the test runner, is configured to not run tests from a remote drive. When I copied the project to a local drive it worked fine, but I needed it on a shared drive (can not remember why).

I read that it can be configured to work from a shared drive, but never got to do it as by the time I discovered the solution I had switched to MonoDevelop on Debian.

Fun new approach to "one-lining" the case of an anonymously split thing such that you don't split it twice, but do all the work in one line is using the walrus operator, :=, to perform assignment as an expression, allowing both:

first, last = (split_str := a.split("-"))[0], split_str[-1]

and:

first, last = (split_str := a.split("-"))[::len(split_str)-1]

Mind you, in both cases it's essentially exactly equivalent to doing on one line:

split_str = a.split("-")

then following up with one of:

first, last = split_str[0], split_str[-1]
first, last = split_str[::len(split_str)-1]

including the fact that split_str persists beyond the line it was used and accessed on. It's just technically meeting the requirements of one-lining, while being fairly ugly. I'd never recommend it over unpacking or itemgetter solutions, even if one-lining was mandatory (ruling out the non-walrus versions that explicitly index or slice a named variable and must refer to said named variable twice).

var groupedCustomerList = userList
    .GroupBy(u => u.GroupID)
    .Select(grp => grp.ToList())
    .ToList();

You're using curvy-braces when you should be using parentheses.

A where statement is kept inside a scriptblock, which is defined using curvy baces { }. To isolate/wrap you tests, you should use parentheses ().

I would also suggest trying to do the filtering on the remote computer. Try:

Invoke-Command -computername SERVERNAME {
    Get-ChildItem -path E:\dfsroots\datastore2\public |
    Where-Object { ($_.extension -eq "xls" -or $_.extension -eq "xlk") -and $_.creationtime -ge "06/01/2014" }
}

You can call a service from your controller that returns a promise and then use it in your controller. And further use $emit or $broadcast to inform other controllers about it. In my case, I had to make http calls through my service, so I did something like this :

function ParentController($scope, testService) {
    testService.getList()
        .then(function(data) {
            $scope.list = testService.list;
        })
        .finally(function() {
            $scope.$emit('listFetched');
        })


    function ChildController($scope, testService) {
        $scope.$on('listFetched', function(event, data) {
            // use the data accordingly
        })
    }

and my service looks like this

    app.service('testService', ['$http', function($http) {

        this.list = [];

        this.getList = function() {
            return $http.get(someUrl)
                .then(function(response) {
                    if (typeof response.data === 'object') {
                        list = response.data.results;

                        return response.data;
                    } else {
                        // invalid response
                        return $q.reject(response.data);
                    }

                }, function(response) {
                    // something went wrong
                    return $q.reject(response.data);
                });

        }

    }])

I solved it in two steps. To rename folder using mv command you need rights to do so, if you don't have right you can follow these steps. Suppose you want to rename casesensitive to Casesensitive.

Step 1: Rename the folder (casesensitive) to something else from explorer. eg Rename casesensitive to folder1 commit this change.

Step 2: Rename this newly named folder(folder1) to the expected case sensitive name (Casesensitive ) eg. Rename folder1 to Casesensitive. Commit this change.

Simplest solution: You're probably running out of virtual address space (any other form of error usually means running really slowly for a long time before you finally get a MemoryError). This is because a 32 bit application on Windows (and most OSes) is limited to 2 GB of user mode address space (Windows can be tweaked to make it 3 GB, but that's still a low cap). You've got 8 GB of RAM, but your program can't use (at least) 3/4 of it. Python has a fair amount of per-object overhead (object header, allocation alignment, etc.), odds are the strings alone are using close to a GB of RAM, and that's before you deal with the overhead of the dictionary, the rest of your program, the rest of Python, etc. If memory space fragments enough, and the dictionary needs to grow, it may not have enough contiguous space to reallocate, and you'll get a MemoryError.

Install a 64 bit version of Python (if you can, I'd recommend upgrading to Python 3 for other reasons); it will use more memory, but then, it will have access to a lot more memory space (and more physical RAM as well).

If that's not enough, consider converting to a sqlite3 database (or some other DB), so it naturally spills to disk when the data gets too large for main memory, while still having fairly efficient lookup.

Besides putting the correct entries in your .gitignore file, if you're trying to ignore something already added to the repo, you have to do git rm -r /path/to/dir and commit that before you add the dir to your .gitignore file. Otherwise the only thing git will ignore is your ignore directive.

Usage from @jpmc26

driver.close and driver.quit are two different methods for closing the browser session in Selenium WebDriver. Understanding both of them and knowing when to use each method is important in your test execution. Therefore, I have tried to shed some light on both of these methods.

driver.close - This method closes the browser window on which the focus is set. Despite the familiar name for this method, WebDriver does not implement the AutoCloseable interface.

driver.quit – This method basically calls driver.dispose a now internal method which in turn closes all of the browser windows and ends the WebDriver session gracefully.

driver.dispose - As mentioned previously, is an internal method of WebDriver which has been silently dropped according to another answer - Verification needed. This method really doesn't have a use-case in a normal test workflow as either of the previous methods should work for most use cases.

Explanation use case: You should use driver.quit whenever you want to end the program. It will close all opened browser windows and terminates the WebDriver session. If you do not use driver.quit at the end of the program, the WebDriver session will not close properly and files would not be cleared from memory. This may result in memory leak errors.

The above explanation should explain the difference between driver.close and driver.quit methods in WebDriver. I hope you find it useful.

The following website has some good tips on selenium testing : Link

use textstyle property as bold

android:textStyle = "bold";

I know that the question was how to do it with Jquery, but you can achieve the same affect with simple css and just a little jquery...

For example, you have a div with 'box' class, add the following css

.box {
background-color: black;
-webkit-transition: background 0.5s linear;
-moz-transition: background 0.5s linear;
-ms-transition: background 0.5s linear;
-o-transition: background 0.5s linear;
transition: background 0.5s linear;
}

and then use AddClass function to add another class with different background color like 'box highlighted' or something like that with the following css:

.box.highlighted {
  background-color: white;
}

I am a beginner and maybe there are some disadvantages of this method but maybe it'll be helpful for somebody

Here's a codepen: https://codepen.io/anon/pen/baaLYB

This is an old question, but everybody fails to mention that Enums are actually Serializable and therefore can perfectly be added to an Intent as an extra. Like this:

public enum AwesomeEnum {
  SOMETHING, OTHER;
}

intent.putExtra("AwesomeEnum", AwesomeEnum.SOMETHING);

AwesomeEnum result = (AwesomeEnum) intent.getSerializableExtra("AwesomeEnum");

The suggestion to use static or application-wide variables is a really bad idea. This really couples your activities to a state managing system, and it is hard to maintain, debug and problem bound.

ALTERNATIVES:

A good point was noted by tedzyc about the fact that the solution provided by Oderik gives you an error. However, the alternative offered is a bit cumbersome to use (even using generics).

If you are really worried about the performance of adding the enum to an Intent I propose these alternatives instead:

OPTION 1:

public enum AwesomeEnum {
  SOMETHING, OTHER;
  private static final String name = AwesomeEnum.class.getName();
  public void attachTo(Intent intent) {
    intent.putExtra(name, ordinal());
  }
  public static AwesomeEnum detachFrom(Intent intent) {
    if(!intent.hasExtra(name)) throw new IllegalStateException();
    return values()[intent.getIntExtra(name, -1)];
  }
}

Usage:

// Sender usage
AwesomeEnum.SOMETHING.attachTo(intent);
// Receiver usage
AwesomeEnum result = AwesomeEnum.detachFrom(intent);

OPTION 2: (generic, reusable and decoupled from the enum)

public final class EnumUtil {
    public static class Serializer<T extends Enum<T>> extends Deserializer<T> {
        private T victim;
        @SuppressWarnings("unchecked") 
        public Serializer(T victim) {
            super((Class<T>) victim.getClass());
            this.victim = victim;
        }
        public void to(Intent intent) {
            intent.putExtra(name, victim.ordinal());
        }
    }
    public static class Deserializer<T extends Enum<T>> {
        protected Class<T> victimType;
        protected String name;
        public Deserializer(Class<T> victimType) {
            this.victimType = victimType;
            this.name = victimType.getName();
        }
        public T from(Intent intent) {
            if (!intent.hasExtra(name)) throw new IllegalStateException();
            return victimType.getEnumConstants()[intent.getIntExtra(name, -1)];
        }
    }
    public static <T extends Enum<T>> Deserializer<T> deserialize(Class<T> victim) {
        return new Deserializer<T>(victim);
    }
    public static <T extends Enum<T>> Serializer<T> serialize(T victim) {
        return new Serializer<T>(victim);
    }
}

Usage:

// Sender usage
EnumUtil.serialize(AwesomeEnum.Something).to(intent);
// Receiver usage
AwesomeEnum result = 
EnumUtil.deserialize(AwesomeEnum.class).from(intent);

OPTION 3 (with Kotlin):

It's been a while, but since now we have Kotlin, I thought I would add another option for the new paradigm. Here we can make use of extension functions and reified types (which retains the type when compiling).

inline fun <reified T : Enum<T>> Intent.putExtra(victim: T): Intent =
    putExtra(T::class.java.name, victim.ordinal)

inline fun <reified T: Enum<T>> Intent.getEnumExtra(): T? =
    getIntExtra(T::class.java.name, -1)
        .takeUnless { it == -1 }
        ?.let { T::class.java.enumConstants[it] }

There are a few benefits of doing it this way.

• We don't require the "overhead" of an intermediary object to do the serialization as it's all done in place thanks to inline which will replace the calls with the code inside the function.
• The functions are more familiar as they are similar to the SDK ones.
• The IDE will autocomplete these functions which means there is no need to have previous knowledge of the utility class.

One of the downsides is that, if we change the order of the Emums, then any old reference will not work. This can be an issue with things like Intents inside pending intents as they may survive updates. However, for the rest of the time, it should be ok.

It's important to note that other solutions, like using the name instead of the position, will also fail if we rename any of the values. Although, in those cases, we get an exception instead of the incorrect Enum value.

Usage:

// Sender usage
intent.putExtra(AwesomeEnum.SOMETHING)
// Receiver usage
val result = intent.getEnumExtra<AwesomeEnum>()

i would suppose to set the EditTexts width to wrap_content and put the two buttons into a LinearLayout whose width is fill_parent and weight set to 1.

[[]]*3 is not the same as [[], [], []].

It's as if you'd said

a = []
listy = [a, a, a]

In other words, all three list references refer to the same list instance.

per the docs

Configure and ConfigureServices support environment specific versions of the form Configure{EnvironmentName} and Configure{EnvironmentName}Services:

You can do something like this...

public void ConfigureProductionServices(IServiceCollection services)
{
    ConfigureCommonServices(services);

    //Services only for production
    services.Configure();
}

public void ConfigureDevelopmentServices(IServiceCollection services)
{
    ConfigureCommonServices(services);

    //Services only for development
    services.Configure();
}

public void ConfigureStagingServices(IServiceCollection services)
{
    ConfigureCommonServices(services);

    //Services only for staging
    services.Configure();
}

private void ConfigureCommonServices(IServiceCollection services)
{
    //Services common to each environment
}

Combining @AdamRosenfield answer, @Christoph comment and another trick to handle plain C enums I suggest:

// In a header file
typedef enum {
  JSON = 0,         // explicitly indicate starting index
  XML,
  Atom,
  RSS,

  FormatTypeCount,  // keep track of the enum size automatically
} FormatType;
extern NSString *const FormatTypeName[FormatTypeCount];


// In a source file
NSString *const FormatTypeName[FormatTypeCount] = {
  [JSON] = @"JSON",
  [XML] = @"XML",
  [Atom] = @"Atom",
  [RSS] = @"RSS",
};


// Usage
NSLog(@"%@", FormatTypeName[XML]);

In the worst case - like if you change the enum but forget to change the names array - it will return nil for this key.

Use RxJS in a Service

What about in a situation where you have a Service that's holding state for example. How could I push changes to that Service, and other random components on the page be aware of such a change? Been struggling with tackling this problem lately

Build a service with RxJS Extensions for Angular.

<script src="//unpkg.com/angular/angular.js"></script>
<script src="//unpkg.com/rx/dist/rx.all.js"></script>
<script src="//unpkg.com/rx-angular/dist/rx.angular.js"></script>

var app = angular.module('myApp', ['rx']);

app.factory("DataService", function(rx) {
  var subject = new rx.Subject(); 
  var data = "Initial";

  return {
      set: function set(d){
        data = d;
        subject.onNext(d);
      },
      get: function get() {
        return data;
      },
      subscribe: function (o) {
         return subject.subscribe(o);
      }
  };
});

Then simply subscribe to the changes.

app.controller('displayCtrl', function(DataService) {
  var $ctrl = this;

  $ctrl.data = DataService.get();
  var subscription = DataService.subscribe(function onNext(d) {
      $ctrl.data = d;
  });

  this.$onDestroy = function() {
      subscription.dispose();
  };
});

Clients can subscribe to changes with DataService.subscribe and producers can push changes with DataService.set.

The DEMO on PLNKR.

Don't forget you can also use pure JavaScript to deal with this situation, using:

window.scrollTo(x-coord, y-coord);

Sorry to reanimate a dead thread, but I have just been dealing with this myself, and after finding all sorts of crazy bloated solutions, I managed to come up with this.

[Long]$actualSize = 0
foreach ($item in (Get-ChildItem $path -recurse | Where {-not $_.PSIsContainer} | ForEach-Object {$_.FullName})) {
   $actualSize += (Get-Item $item).length
}

Quickly and in few lines of code gives me a folder size in Bytes, than can easily be converted to any units you want with / 1MB or the like. Am I missing something? Compared to this overwrought mess it seems rather simple and to the point. Not to mention that code doesn't even work since the called function is not the same name as the defined function. And has been wrong for 6 years. ;) So, any reasons NOT to use this stripped down approach?

As of mid 2017 To quickly get to the settings files press ctrl + shift + p and enter settings, there you will find the user settings and the workspace settings, be aware that the workspace settings will override the user settings, so it's better to use the latter directly to make it a global change (workspace settings will create a folder in your project root), from there you will have the option to add the option "editor.fontSize": 14 to your settings as a quick suggestion, but you can do it yourself and change the value to your preferred font size.

To sum it up:

1. ctrl + shift + p

2. select "user settings"

3. add "editor.fontSize": 14

One example of Haskell in action is xmonad, a "featureful window manager in less than 1200 lines of code".

In the spirit of arrow sexiness, you could create a micro clamp/constrain/gate/&c. function using rest parameters

var clamp = (...v) => v.sort((a,b) => a-b)[1];

Then just pass in three values

clamp(100,-3,someVar);

That is, again, if by sexy, you mean 'short'

I needed to template a few files with minimal tooling and for me the issue with above sed -e '/../r file.txt is that it only appends the file after it prints out the rest of the match, it doesn't replace it.

This doesn't do it (all matches are replaced and pattern matching continues from same point)

#!/bin/bash

TEMPDIR=$(mktemp -d "${TMPDIR:-/tmp/}$(basename $0).XXXXXXXXXXXX")
# remove on exit
trap "rm -rf $TEMPDIR" EXIT

DCTEMPLATE=$TEMPDIR/dctemplate.txt
DCTEMPFILE=$TEMPDIR/dctempfile.txt

# template that will replace
printf "0replacement
1${SHELL} data
2anotherlinenoEOL" > $DCTEMPLATE

# test data
echo -e "xxy \n987 \nxx xx\n yz yxxyy" > $DCTEMPFILE

# print original for debug
echo "---8<--- $DCTEMPFILE"
cat $DCTEMPFILE
echo "---8<--- $DCTEMPLATE"
cat $DCTEMPLATE
echo "---8<---"

# replace 'xx' -> contents of $DCTEMPFILE
perl -e "our \$fname = '${DCTEMPLATE}';" -pe 's/xx/`cat $fname`/eg' ${DCTEMPFILE}

In my case, I want to add a column to a Primary key (column4). I used this script to add column4

ALTER TABLE TableA
DROP CONSTRAINT [PK_TableA]

ALTER TABLE TableA
ADD CONSTRAINT [PK_TableA] PRIMARY KEY (
    [column1] ASC,
    [column2] ASC, 
    [column3] ASC,
    [column4] ASC
)

We can have this in 2 ways,

Either have 2 form submissions within the same View and having 2 Action methods at the controller but you will need to have the required fields to be submitted with the form to be placed within

ex is given here with code Multiple forms in view asp.net mvc with multiple submit buttons

Or

Have 2 or multiple submit buttons say btnSubmit1 and btnSubmit2 and check on the Action method which button was clicked using the code

if (Request.Form["btnSubmit1"] != null)
{
 //
}
if (Request.Form["btnSubmit2"] != null)
{
 //
}

Looks like the installed driver was in bad state. Here is what I did to make it work:

1. Delete the device from Device Manager.
2. Rescan for hardware changes.
3. "Slate 21" will show up with "Unknown driver" status.
4. Click on "Update Driver" and select /extras/google/usb_driver
5. Device Manager will find the driver and warn you about installing it. Select "Yes."

This time the device got installed properly.

Note that I didn't have to modify winusb.inf file or update any other driver.

Hope this helps.

If your button still doesn't show anything with title, check if your button is NOT disabled

Lazy Set

VARIABLE = value

Normal setting of a variable, but any other variables mentioned with the value field are recursively expanded with their value at the point at which the variable is used, not the one it had when it was declared

Immediate Set

VARIABLE := value

Setting of a variable with simple expansion of the values inside - values within it are expanded at declaration time.

Lazy Set If Absent

VARIABLE ?= value

Setting of a variable only if it doesn't have a value. value is always evaluated when VARIABLE is accessed. It is equivalent to

ifeq ($(origin FOO), undefined)
  FOO = bar
endif

See the documentation for more details.

Append

VARIABLE += value

Appending the supplied value to the existing value (or setting to that value if the variable didn't exist)

This is what I'm using nowadays if the test result is produced asynchronously.

public class TestUtil {

    public static <R> R await(Consumer<CompletableFuture<R>> completer) {
        return await(20, TimeUnit.SECONDS, completer);
    }

    public static <R> R await(int time, TimeUnit unit, Consumer<CompletableFuture<R>> completer) {
        CompletableFuture<R> f = new CompletableFuture<>();
        completer.accept(f);
        try {
            return f.get(time, unit);
        } catch (InterruptedException | TimeoutException e) {
            throw new RuntimeException("Future timed out", e);
        } catch (ExecutionException e) {
            throw new RuntimeException("Future failed", e.getCause());
        }
    }
}

Using static imports, the test reads kinda nice. (note, in this example I'm starting a thread to illustrate the idea)

    @Test
    public void testAsync() {
        String result = await(f -> {
            new Thread(() -> f.complete("My Result")).start();
        });
        assertEquals("My Result", result);
    }

If f.complete isn't called, the test will fail after a timeout. You can also use f.completeExceptionally to fail early.

Your __init__.py should have a docstring.

Although all the functionality is implemented in modules and subpackages, your package docstring is the place to document where to start. For example, consider the python email package. The package documentation is an introduction describing the purpose, background, and how the various components within the package work together. If you automatically generate documentation from docstrings using sphinx or another package, the package docstring is exactly the right place to describe such an introduction.

For any other content, see the excellent answers by firecrow and Alex Martelli.

You can create functions in react components. It is actually regular ES6 class which inherits from React.Component. Just be careful and bind it to the correct context in onClick event:

export default class Archive extends React.Component { 

    saySomething(something) {
        console.log(something);
    }

    handleClick(e) {
        this.saySomething("element clicked");
    }

    componentDidMount() {
        this.saySomething("component did mount");
    }

    render() {
        return <button onClick={this.handleClick.bind(this)} value="Click me" />;
    }
}

Thanks to @tgrrr for a simple solution, especially when 3rd party library is not wanted (such as React-Bootstrap). However, this solution has a problem: modal container is embedded inside react component, which leads to modal-under-background issue when outside react component (or its parent element) has position style as fixed/relative/absolute. I met this problem and came up to a new solution:

"use strict";

var React = require('react');
var ReactDOM = require('react-dom');

var SampleModal = React.createClass({
  render: function() {
    return (
      <div className="modal fade" tabindex="-1" role="dialog">
        <div className="modal-dialog">
          <div className="modal-content">
            <div className="modal-header">
              <button type="button" className="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
              <h4 className="modal-title">Title</h4>
            </div>
            <div className="modal-body">
              <p>Modal content</p>
            </div>
            <div className="modal-footer">
              <button type="button" className="btn btn-default" data-dismiss="modal">Cancel</button>
              <button type="button" className="btn btn-primary">OK</button>
            </div>
          </div>
        </div>
      </div>
    );
  }
});

var sampleModalId = 'sample-modal-container';
var SampleApp = React.createClass({
  handleShowSampleModal: function() {
    var modal = React.cloneElement(<SampleModal></SampleModal>);
    var modalContainer = document.createElement('div');
    modalContainer.id = sampleModalId;
    document.body.appendChild(modalContainer);
    ReactDOM.render(modal, modalContainer, function() {
      var modalObj = $('#'+sampleModalId+'>.modal');
      modalObj.modal('show');
      modalObj.on('hidden.bs.modal', this.handleHideSampleModal);
    }.bind(this));
  },
  handleHideSampleModal: function() {
    $('#'+sampleModalId).remove();
  },
  render: function(){    
    return (
      <div>
        <a href="javascript:;" onClick={this.handleShowSampleModal}>show modal</a>
      </div>
    )
  }
});

module.exports = SampleApp;

The main idea is:

1. Clone the modal element (ReactElement object).
2. Create a div element and insert it into document body.
3. Render the cloned modal element in the newly inserted div element.
4. When the render is finished, show modal. Also, attach an event listener, so that when modal is hidden, the newly inserted div element will be removed.

You can use PowerShell

$AttachmentPath = "CV File location"
$QueryFmt= "Query"

Invoke-Sqlcmd -ServerInstance Server -Database DBName -Query $QueryFmt | Export-CSV $AttachmentPath

git stash pop throws away the (topmost, by default) stash after applying it, whereas git stash apply leaves it in the stash list for possible later reuse (or you can then git stash drop it).

This happens unless there are conflicts after git stash pop, in which case it will not remove the stash, leaving it to behave exactly like git stash apply.

Another way to look at it: git stash pop is git stash apply && git stash drop.

It seems this is one of the rare occasions on which use of an attribute is actually appropriate. jQuery's attr() method will not help you because in most cases (including this) it actually sets a property, not an attribute, making the choice of its name look somewhat foolish. [UPDATE: Since jQuery 1.6.1, the situation has changed slightly]

IE has some problems with the DOM setAttribute method but in this case it should be fine:

this.setAttribute("checked", "checked");

In IE, this will always actually make the checkbox checked. In other browsers, if the user has already checked and unchecked the checkbox, setting the attribute will have no visible effect. Therefore, if you want to guarantee the checkbox is checked as well as having the checked attribute, you need to set the checked property as well:

this.setAttribute("checked", "checked");
this.checked = true;

To uncheck the checkbox and remove the attribute, do the following:

this.setAttribute("checked", ""); // For IE
this.removeAttribute("checked"); // For other browsers
this.checked = false;

This answer is based on Mitja Semolic's excellent earlier answer. I've converted it to swift 3, added an explanation to what's happening in coments, made it an extension of a UIViewController so any VC can call it at will, added an unblurred view to show selective application, and added a completion block so that the calling view controller can do whatever it wants at the completion of the blur.

    import UIKit
//This extension implements a blur to the entire screen, puts up a HUD and then waits and dismisses the view.
    extension UIViewController {
        func blurAndShowHUD(duration: Double, message: String, completion: @escaping () -> Void) { //with completion block
            //1. Create the blur effect & the view it will occupy
            let blurEffect = UIBlurEffect(style: UIBlurEffectStyle.light)
            let blurEffectView = UIVisualEffectView()//(effect: blurEffect)
            blurEffectView.frame = self.view.bounds
            blurEffectView.autoresizingMask = [.flexibleWidth, .flexibleHeight]

        //2. Add the effect view to the main view
            self.view.addSubview(blurEffectView)
        //3. Create the hud and add it to the main view
        let hud = HudView.getHUD(view: self.view, withMessage: message)
        self.view.addSubview(hud)
        //4. Begin applying the blur effect to the effect view
        UIView.animate(withDuration: 0.01, animations: {
            blurEffectView.effect = blurEffect
        })
        //5. Halt the blur effects application to achieve the desired blur radius
        self.view.pauseAnimationsInThisView(delay: 0.004)
        //6. Remove the view (& the HUD) after the completion of the duration
        DispatchQueue.main.asyncAfter(deadline: .now() + duration) {
            blurEffectView.removeFromSuperview()
            hud.removeFromSuperview()
            self.view.resumeAnimationsInThisView()
            completion()
        }
    }
}

extension UIView {
    public func pauseAnimationsInThisView(delay: Double) {
        let time = delay + CFAbsoluteTimeGetCurrent()
        let timer = CFRunLoopTimerCreateWithHandler(kCFAllocatorDefault, time, 0, 0, 0, { timer in
            let layer = self.layer
            let pausedTime = layer.convertTime(CACurrentMediaTime(), from: nil)
            layer.speed = 0.0
            layer.timeOffset = pausedTime
        })
        CFRunLoopAddTimer(CFRunLoopGetCurrent(), timer, CFRunLoopMode.commonModes)
    }
    public func resumeAnimationsInThisView() {
        let pausedTime  = layer.timeOffset

        layer.speed = 1.0
        layer.timeOffset = 0.0
        layer.beginTime = layer.convertTime(CACurrentMediaTime(), from: nil) - pausedTime
    }
}

I've confirmed that it works with both iOS 10.3.1 and iOS 11

This line of JS code takes the link without params (ie before '?') and then append params to it.

window.location.href = (window.location.href.split('?')[0]) + "?p1=ABC&p2=XYZ";

The above line of code is appending two params p1 and p2 with respective values 'ABC' and 'XYZ' (for better understanding).

You can access the keys with ${!array[@]}:

bash-4.0$ echo "${!array[@]}"
foo bar

Then, iterating over the key/value pairs is easy:

for i in "${!array[@]}"
do
  echo "key :" $i
  echo "value:" ${array[$i]}
done

If all that you want is to see the disassembly with the INTC call, use objdump -d as someone mentioned but use the -static option when compiling. Otherwise the fopen function is not compiled into the elf and is linked at runtime.

To provide a bit more clarity, let's look at a DataFrame with two levels in its index (a MultiIndex).

index = pd.MultiIndex.from_product([['TX', 'FL', 'CA'], 
                                    ['North', 'South']], 
                                   names=['State', 'Direction'])

df = pd.DataFrame(index=index, 
                  data=np.random.randint(0, 10, (6,4)), 
                  columns=list('abcd'))

The reset_index method, called with the default parameters, converts all index levels to columns and uses a simple RangeIndex as new index.

df.reset_index()

Use the level parameter to control which index levels are converted into columns. If possible, use the level name, which is more explicit. If there are no level names, you can refer to each level by its integer location, which begin at 0 from the outside. You can use a scalar value here or a list of all the indexes you would like to reset.

df.reset_index(level='State') # same as df.reset_index(level=0)

In the rare event that you want to preserve the index and turn the index into a column, you can do the following:

# for a single level
df.assign(State=df.index.get_level_values('State'))

# for all levels
df.assign(**df.index.to_frame())

Set the JVM memory:

export _JAVA_OPTIONS=-Xmx512M

In some cases, instead of relying on downward API, programmatically reading the local IP address (from network interfaces) from inside of the container also works.

For example, in golang: https://stackoverflow.com/a/31551220/6247478

try this code

in example code use axios get rest API.

in mounted

  mounted(){
    var config = {
    headers: { 
      'x-rapidapi-host': 'covid-19-coronavirus-statistics.p.rapidapi.com',
      'x-rapidapi-key': '5156f83861mshd5c5731412d4c5fp18132ejsn8ae65e661a54' 
      }
   };
   axios.get('https://covid-19-coronavirus-statistics.p.rapidapi.com/v1/stats? 
    country=Thailand',  config)
    .then((response) => {
    console.log(response.data);
  });
}

Hope is help.

Breaking out of a for-loop is a little strange to me, since the semantics of a for-loop typically indicate that it will execute a specified number of times. However, it's not bad in all cases; if you're searching for something in a collection and want to break after you find it, it's useful. Breaking out of nested loops, however, isn't possible in C++; it is in other languages through the use of a labeled break. You can use a label and a goto, but that might give you heartburn at night..? Seems like the best option though.

Use something like this to update your tomcat users.

<role rolename="manager-gui"/>
<user username="admin" password="admin" roles="manager-gui"/>

Tomcat users file is located inside conf folder of tomcat installation. To find the path of catalina_base you can use the command: ps aux | grep catalina You can find one of the values -Dcatalina.base=/usr/local/Cellar/tomcat/9.0.37/libexec

Most Important:

Don't forget to remove the comment lines from the tomcat-users.xml just before the start of the roles. <!-- -->

use Illuminate\Http\Request;
public function store(Request $request){
   dd($request->all());
}

is same in context saying

use Request;
public function store(){
   dd(Request::all());
}

You just need to bind a variable into the directive "ng-class" and change it from the controller. Here is an example of how to do this:

var app = angular.module("ap",[]);_x000D_
_x000D_
app.controller("con",function($scope){_x000D_
  $scope.class = "red";_x000D_
  $scope.changeClass = function(){_x000D_
    if ($scope.class === "red")_x000D_
      $scope.class = "blue";_x000D_
    else_x000D_
      $scope.class = "red";_x000D_
  };_x000D_
});

.red{_x000D_
  color:red;_x000D_
}_x000D_
_x000D_
.blue{_x000D_
  color:blue;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
<body ng-app="ap" ng-controller="con">_x000D_
  <div ng-class="class">{{class}}</div>_x000D_
  <button ng-click="changeClass()">Change Class</button>    _x000D_
</body>

Here is the example working on jsFiddle

Just to add to the above..you can use the alpha channel with the new color attributes eg. rgba(0,0,0,0) ok so this is black but with zero opacity so as a parent it will not affect the child. This only works on Chrome, FF, Safari and....I thin O.

convert your hex colours to RGBA

You must use prefix "php5.6-" instead of "php5-" as in ubuntu 14.04 and olders:

sudo apt-get install php5.6 php5.6-mcrypt

Just download your provisioning profile again from your developer account. And sign out all developer accounts from Xcode ? Preferences ? Accounts ? *Select Account showing at left and press -(subtract sign)

After deleting all accounts, press the + sign (add) button and sign in with all developer accounts.

It will work like a charm...

Make file executable:

chmod +x file

Find location of perl:

which perl

This should return something like

/bin/perl sometimes /usr/local/bin

Then in the first line of your script add:

#!"path"/perl with path from above e.g.

#!/bin/perl

Then you can execute the file

./file

There may be some issues with the PATH, so you may want to change that as well ...

I know this is a late entry but I have created a simple upload directive. Which you can get working in no time!

<input type="file" multiple ng-simple-upload web-api-url="/api/post"
       callback-fn="myCallback" />

ng-simple-upload more on Github with an example using Web API.

This works...

It's also possible to use jQuery's .load()

$('#submitform').click(function() {
  $('#showresults').load('getinfo.asp #showresults', {
    txtsearch: $('#appendedInputButton').val()
  }, function() {
    // alert('Load was performed.')
    // $('#showresults').slideDown('slow')
  });
});

unlike $.get(), allows us to specify a portion of the remote document to be inserted. This is achieved with a special syntax for the url parameter. If one or more space characters are included in the string, the portion of the string following the first space is assumed to be a jQuery selector that determines the content to be loaded.

We could modify the example above to use only part of the document that is fetched:

$( "#result" ).load( "ajax/test.html #container" );

When this method executes, it retrieves the content of ajax/test.html, but then jQuery parses the returned document to find the element with an ID of container. This element, along with its contents, is inserted into the element with an ID of result, and the rest of the retrieved document is discarded.

You can make use of dir() which is pre-defined in Python.

import module_name
dir(module_name)

You can also pass an object to dir() as

dir(object_name)

If the object is an object of a pre-defined class such as int, str, etc. it displays the methods in it (you may know those methods as built in functions). If that object is created for a user-defined class, it displays all the methods given in that class.

And to complement Rich's recursive answer, a non-recursive method.

Public Sub NonRecursiveMethod()
    Dim fso, oFolder, oSubfolder, oFile, queue As Collection

    Set fso = CreateObject("Scripting.FileSystemObject")
    Set queue = New Collection
    queue.Add fso.GetFolder("your folder path variable") 'obviously replace

    Do While queue.Count > 0
        Set oFolder = queue(1)
        queue.Remove 1 'dequeue
        '...insert any folder processing code here...
        For Each oSubfolder In oFolder.SubFolders
            queue.Add oSubfolder 'enqueue
        Next oSubfolder
        For Each oFile In oFolder.Files
            '...insert any file processing code here...
        Next oFile
    Loop

End Sub

You can use a queue for FIFO behaviour (shown above), or you can use a stack for LIFO behaviour which would process in the same order as a recursive approach (replace Set oFolder = queue(1) with Set oFolder = queue(queue.Count) and replace queue.Remove(1) with queue.Remove(queue.Count), and probably rename the variable...)

This is a nice example: The Repository Pattern Example in C#

Basically, repository hides the details of how exactly the data is being fetched/persisted from/to the database. Under the covers:

• for reading, it creates the query satisfying the supplied criteria and returns the result set
• for writing, it issues the commands necessary to make the underlying persistence engine (e.g. an SQL database) save the data

The ConnectTimeout option allows you to tell your ssh client how long you're willing to wait for a connection before returning an error. By setting ConnectTimeout to 1, you're effectively saying "try for at most 1 second and then fail if you haven't connected yet".

The problem is that when you connect by name, the DNS lookup can take several seconds. Connecting by IP address is much faster, and may actually work in one second or less. What sinelaw is experiencing is that every attempt to connect by DNS name is failing to occur within one second. The default setting of ConnectTimeout defers to the linux kernel connect timeout, which is usually pretty long.

So, I got this same exact error for a completely different reason. Due to a totally separate, but known Homebrew + pip bug, I had followed this workaround listed on Google Cloud's help docs, where you create a .pydistutils.cfg file in your home directory. This file has special config that you're only supposed to use for your install of certain libraries. I should have removed that disutils.cfg file after installing the packages, but I forgot to do so. So the fix for me was actually just...

rm ~/.pydistutils.cfg.

And then everything worked as normal. Of course, if you have some config in that file for a real reason, then you won't want to just straight rm that file. But in case anyone else did that workaround, and forgot to remove that file, this did the trick for me!

Use the Take(int n) method:

var q = query.Take(10);

Found a similar way to fix this issue (at least it did for me).

1. First check where the CLI php.ini is located:

   php -i | grep "php.ini"

2. In my case I ended up with : Configuration File (php.ini) Path => /etc

3. Then cd .. all the way back and cd into /etc, do ls in my case php.ini didn't show up, only a php.ini.default

4. Now, copy the php.ini.default file named as php.ini:

   sudo cp php.ini.default php.ini

5. In order to edit, change the permissions of the file:

   sudo chmod ug+w php.ini

   sudo chgrp staff php.ini

6. Open directory and edit the php.ini file:

   open .

   Tip: If you are not able to edit the php.ini due to some permissions issue then copy 'php.ini.default' and paste it on your desktop and rename it to 'php.ini' then open it and edit it following step 7. Then move (copy+paste) it in /etc folder. Issue will be resolved.

7. Search for [Date] and make sure the following line is in the correct format:

   date.timezone = "Europe/Amsterdam"

I hope this could help you out.

I solved this issue to update .htaccess file inside your workspace (like C:\xampp\htdocs\Nayan\.htaccess in my case).

Just update or add this php_value max_execution_time 300 line before # END WordPress. Then save the file and try to install again.

If the error occurs again, you can maximize the value from 300 to 600.

From the Flask API Documentation (v. 0.10):

flask.redirect(location, code=302, Response=None)

Returns a response object (a WSGI application) that, if called, redirects the client to the target location. Supported codes are 301, 302, 303, 305, and 307. 300 is not supported because it’s not a real redirect and 304 because it’s the answer for a request with a request with defined If-Modified-Since headers.

New in version 0.6: The location can now be a unicode string that is encoded using the iri_to_uri() function.

Parameters:

• location – the location the response should redirect to.
• code – the redirect status code. defaults to 302.
• Response (class) – a Response class to use when instantiating a response. The default is werkzeug.wrappers.Response if unspecified.

This is in-line with what JP Mercier initially suggested about using Pandas, but with a major modification: If you read data into Pandas in chunks, it should be more malleable. Meaning, that you can parse a much larger file than Pandas can actually handle as a single piece and pass it to Spark in smaller sizes. (This also answers the comment about why one would want to use Spark if they can load everything into Pandas anyways.)

from pyspark import SparkContext
from pyspark.sql import SQLContext
import pandas as pd

sc = SparkContext('local','example')  # if using locally
sql_sc = SQLContext(sc)

Spark_Full = sc.emptyRDD()
chunk_100k = pd.read_csv("Your_Data_File.csv", chunksize=100000)
# if you have headers in your csv file:
headers = list(pd.read_csv("Your_Data_File.csv", nrows=0).columns)

for chunky in chunk_100k:
    Spark_Full +=  sc.parallelize(chunky.values.tolist())

YourSparkDataFrame = Spark_Full.toDF(headers)
# if you do not have headers, leave empty instead:
# YourSparkDataFrame = Spark_Full.toDF()
YourSparkDataFrame.show()

conn.escape_string()

Cleanest

Try this for a clean approach.

if ( $toptitle.text() == 'Profile' ) // No {} brackets necessary if it's just one line.  
  $toptitle.text('New Word');         

One way, using regular expressions:

>>> s = "how much for the maple syrup? $20.99? That's ridiculous!!!"
>>> re.sub(r'[^\w]', ' ', s)
'how much for the maple syrup   20 99  That s ridiculous   '

• \w will match alphanumeric characters and underscores

• [^\w] will match anything that's not alphanumeric or underscore

Groovy

You can subtract a substring from a string using a regular expression in groovy:

String unquotedString = theString - ~/^"/ - ~/"$/

Regex.Replace(htmlText, "<.*?>", string.Empty);

By default Mocha will read a file named test/mocha.opts that can contain command line arguments. So you could create such a file that contains:

--timeout 5000

Whenever you run Mocha at the command line, it will read this file and set a timeout of 5 seconds by default.

Another way which may be better depending on your situation is to set it like this in a top level describe call in your test file:

describe("something", function () {
    this.timeout(5000); 

    // tests...
});

This would allow you to set a timeout only on a per-file basis.

You could use both methods if you want a global default of 5000 but set something different for some files.

Note that you cannot generally use an arrow function if you are going to call this.timeout (or access any other member of this that Mocha sets for you). For instance, this will usually not work:

describe("something", () => {
    this.timeout(5000); //will not work

    // tests...
});

This is because an arrow function takes this from the scope the function appears in. Mocha will call the function with a good value for this but that value is not passed inside the arrow function. The documentation for Mocha says on this topic:

Passing arrow functions (“lambdas”) to Mocha is discouraged. Due to the lexical binding of this, such functions are unable to access the Mocha context.

That is because, of course, there is no ACTUAL page height. Keep in mind that you scroll throughout the contents of a page vertically not horizontally, creating a limited width but unlimited height. What the selected answer did was to make the table take up the visible area and stay there no matter what(absolute positioning).So theoretically what you were trying to do was impossible

There is no config file unless you create one yourself. However, the port is a parameter of the listen() function. For example, to listen on port 8124:

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(8124, "127.0.0.1");
console.log('Server running at http://127.0.0.1:8124/');

If you're having problems finding a port that's open, you can go to the command line and type:

netstat -ano

To see a list of all ports in use per adapter.

another way, this will scan the table only once instead of twice if you use a subquery

only sql server 2005 and up

select Date, User, Status, Notes 
from (
       select m.*, row_number() over (partition by user order by Date desc) as rn
       from [SOMETABLE] m
     ) m2
where m2.rn = 1;

even simpler, adding up to String[],

use built-in filter filter(StringUtils::isNotEmpty) of org.apache.commons.lang3

import org.apache.commons.lang3.StringUtils;

    String test = "a\nb\n\nc\n";
    String[] lines = test.split("\\n", -1);


    String[]  result = Arrays.stream(lines).filter(StringUtils::isNotEmpty).toArray(String[]::new);
    System.out.println(Arrays.toString(lines));
    System.out.println(Arrays.toString(result));

and output: [a, b, , c, ] [a, b, c]

To calculate the width of the current input, you'll have to embed it in a temporary span element, attach that thing to the DOM, get the computed width (in pixels) using the scrollWidth property and remove the span again. Of course you'll have to ensure that the same font family, font size, etc., is used in the input as well as in the span element. Therefore I assigned the same class to them.

I attached the function to the keyup event, as on keypress the input character is not yet added to the input value, so that will result in the wrong width. Unfortunately, I don't know how to get rid of the scrolling of the input field (when adding characters to the end of the field); it scrolls, because the character is added and shown before adjustWidthOfInput() is called. And, as said, I can't do this the other way round because then you'll have the value of the input field before the pressed character is inserted. I'll try to solve this issue later.

BTW, I only tested this in Firefox (3.6.8), but you'll get the point, I hope.

            backgroundColor:'#000000',

    function(){
        $('#panel').animate({
            height: "0", 
            padding:"0px 0",
            opacity:.2
        }, 500);     
        $('#otherdiv').animate({
            //otherdiv properties here
        }, 500);
});

They're different characters. \r is carriage return, and \n is line feed.

On "old" printers, \r sent the print head back to the start of the line, and \n advanced the paper by one line. Both were therefore necessary to start printing on the next line.

Obviously that's somewhat irrelevant now, although depending on the console you may still be able to use \r to move to the start of the line and overwrite the existing text.

More importantly, Unix tends to use \n as a line separator; Windows tends to use \r\n as a line separator and Macs (up to OS 9) used to use \r as the line separator. (Mac OS X is Unix-y, so uses \n instead; there may be some compatibility situations where \r is used instead though.)

For more information, see the Wikipedia newline article.

EDIT: This is language-sensitive. In C# and Java, for example, \n always means Unicode U+000A, which is defined as line feed. In C and C++ the water is somewhat muddier, as the meaning is platform-specific. See comments for details.

If you want a dynamically sized array, then you should make a list. Not only will you get the .Add() functionality, but as @frode-f explains, dynamic arrays are more memory efficient and a better practice anyway.

And it's so easy to use.

Instead of your array declaration, try this:

$outItems = New-Object System.Collections.Generic.List[System.Object]

Adding items is simple.

$outItems.Add(1)
$outItems.Add("hi")

And if you really want an array when you're done, there's a function for that too.

$outItems.ToArray()

Writing as

var formData = new FormData;
var array = ['1', '2'];
for (var i = 0; i < array.length; i++) {
    formData.append('array_php_side[]', array[i]);
}

you can receive just as normal array post/get by php.

Enabling Relation View in phpMyAdmin / MAMP

If you’re using MAMP for your database driven projects you’ll probably be using phpMyAdmin to administer your MySQL database if you’ve decided to go down that route. If you’re creating a database you might be wondering how to create relationships and foriegn keys for your tables.

Firstly you need to check that you have access to the Relation view. To do this open phpMyAdmin and select a database. You need to make sure your tables’ storage engine is set to use InnoDB. Click on a table within your database and choose the Operations tab. Make sure that the storage engine is set to use InnoDB and save your changes.

Now, go back to your table view and click the Structure tab. Depending on your version of phpMyAdmin you should see a link titled Relation view below the table structure. If you can see it you’re good to go. If you can’t you’ll need to follow the steps below to set phpMyAdmin to enable Relations view.

1. Find /Applications/MAMP/bin/phpMyAdmin/scripts/create_tables.sql
2. I left this file default but you can change the table name to anything you want. I left mine phpMyAdmin
3. Open phpMyAdmin and go to the Import tab.
4. Click the browse button and find the create_tables.sql file and then click Go.
5. The tables required for Relation view will be added to the database you specified.
6. Open /Applications/MAMP/bin/phpMyAdmin/config.inc.php

7. Find the Server(s) configuration code block and replace/uncomment the following code and fill in the values. If you left everything default in the create_tables.sql file then you should just cut and paste the lines below.

   $cfg['Servers'][$i]['pmadb'] = 'phpmyadmin';
   $cfg['Servers'][$i]['bookmarktable'] = 'pma_bookmark';
   $cfg['Servers'][$i]['relation'] = 'pma_relation';
   $cfg['Servers'][$i]['table_info'] = 'pma_table_info';
   $cfg['Servers'][$i]['table_coords'] = 'pma_table_coords';
   $cfg['Servers'][$i]['pdf_pages'] = 'pma_pdf_pages';
   $cfg['Servers'][$i]['column_info'] = 'pma_column_info';
   $cfg['Servers'][$i]['history'] = 'pma_history';
   

8. Save the file and restart MAMP and refresh your phpMyAdmin console.

9. Go to your database and view one of your tables in Structure mode. You should now see the Relation view link.

matplotlib svn has a new function to save images as just an image -- no axes etc. it's a very simple function to backport too, if you don't want to install svn (copied straight from image.py in matplotlib svn, removed the docstring for brevity):

def imsave(fname, arr, vmin=None, vmax=None, cmap=None, format=None, origin=None):
    from matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas
    from matplotlib.figure import Figure

    fig = Figure(figsize=arr.shape[::-1], dpi=1, frameon=False)
    canvas = FigureCanvas(fig)
    fig.figimage(arr, cmap=cmap, vmin=vmin, vmax=vmax, origin=origin)
    fig.savefig(fname, dpi=1, format=format)

This code example that follows shows a basic UILabel configuration.

let lbl = UILabel(frame: CGRectMake(0, 0, 300, 200))
lbl.text = "yourString"

// Enum type, two variations:
lbl.textAlignment = NSTextAlignment.Right
lbl.textAlignment = .Right

lbl.textColor = UIColor.red
lbl.shadowColor = UIColor.black
lbl.font = UIFont(name: "HelveticaNeue", size: CGFloat(22))
self.view.addSubview(lbl)

I usually combine PointToScreen and PointToClient:

Point locationOnForm = control.FindForm().PointToClient(
    control.Parent.PointToScreen(control.Location));

It is important to know not only the types but the mapping of these types to the database types, too:

I was able to customize the hrTag by editing the inline styling as such:

<div class="row"> <!-- You can also position the row if need be. -->
<div class="col-md-12 col-lg-12"><!-- set width of column I wanted mine to stretch most of the screen-->
<hr style="min-width:85%; background-color:#a1a1a1 !important; height:1px;"/>
</div>
 </div>

The hrTag is now thicker and more visible; it's also a darker gray color. The bootstrap code is actually very flexible. As the snippet demonstrates above, you can use inline styling or your own custom code. Hope this helps someone.

Thanks @AhlemMustapha

you have done it the correct way using

curl_setopt($ch, CURLOPT_POSTFIELDS,$body);

but i notice your missing

curl_setopt($ch, CURLOPT_POST,1);

Since this has been the accepted answer for a long time, I feel I need to rectify it with a better answer.

Some comments on the need:

• Your view should not need to access the view controller directly.
• The view should instead be independent of the view controller, and be able to work in different contexts.
• Should you need the view to interface in a way with the view controller, the recommended way, and what Apple does across Cocoa is to use the delegate pattern.

An example of how to implement it follows:

@protocol MyViewDelegate < NSObject >

- (void)viewActionHappened;

@end

@interface MyView : UIView

@property (nonatomic, assign) MyViewDelegate delegate;

@end

@interface MyViewController < MyViewDelegate >

@end

The view interfaces with its delegate (as UITableView does, for instance) and it doesn't care if its implemented in the view controller or in any other class that you end up using.

My original answer follows: I don't recommend this, neither the rest of the answers where direct access to the view controller is achieved

There is no built-in way to do it. While you can get around it by adding a IBOutlet on the UIView and connecting these in Interface Builder, this is not recommended. The view should not know about the view controller. Instead, you should do as @Phil M suggests and create a protocol to be used as the delegate.

I wouldn't go with MSTest. Although it's probably the most future proof of the frameworks with Microsoft behind it's not the most flexible solution. It won't run stand alone without some hacks. So running it on a build server other than TFS without installing Visual Studio is hard. The visual studio test-runner is actually slower than Testdriven.Net + any of the other frameworks. And because the releases of this framework are tied to releases of Visual Studio there are less updates and if you have to work with an older VS you're tied to an older MSTest.

I don't think it matters a lot which of the other frameworks you use. It's really easy to switch from one to another.

I personally use XUnit.Net or NUnit depending on the preference of my coworkers. NUnit is the most standard. XUnit.Net is the leanest framework.

Precedence differs between && and and (&& has higher precedence than and), something that causes confusion when combined with a ternary operator. For instance,

$predA && $predB ? "foo" : "bar"

will return a string whereas

$predA and $predB ? "foo" : "bar"

will return a boolean.

To install a new package and only that, you have two options:

1. Using the require command, just run:

   composer require new/package
   

   Composer will guess the best version constraint to use, install the package, and add it to composer.lock.

   You can also specify an explicit version constraint by running:

   composer require new/package ~2.5
   

–OR–

2. Using the update command, add the new package manually to composer.json, then run:

   composer update new/package
   

If Composer complains, stating "Your requirements could not be resolved to an installable set of packages.", you can resolve this by passing the flag --with-dependencies. This will whitelist all dependencies of the package you are trying to install/update (but none of your other dependencies).

Regarding the question asker's issues with Laravel and mcrypt: check that it's properly enabled in your CLI php.ini. If php -m doesn't list mcrypt then it's missing.

Important: Don't forget to specify new/package when using composer update! Omitting that argument will cause all dependencies, as well as composer.lock, to be updated.

Example from the numpy documentation:

>>> a = numpy.array([[ 0,  1,  2,  3],
               [ 4,  5,  6,  7],
               [ 8,  9, 10, 11],
               [12, 13, 14, 15]])

>>> numpy.delete(a, numpy.s_[1:3], axis=0)                       # remove rows 1 and 2

array([[ 0,  1,  2,  3],
       [12, 13, 14, 15]])

Faced the same problem.

(1) Always check for the typing mistakes in the configuring the .xml files, especially the xml tags.

(2) go to bin dir. and type ./start-all.sh

(3) then type jps , to check if processes are working

Fiddle showing that it works: http://jsfiddle.net/trott/5vu28/.

If you really want this to be on a single line in the source file, you could insert the HTML character references for a line feed and a carriage return as shown in the answer from @Bakudan:

You may use the class java.util.Random with method

char c = (char)(rnd.nextInt(128-32))+32 

20x to get Bytes, which you interpret as ASCII. If you're fine with ASCII.

32 is the offset, from where the characters are printable in general.

You don't need to call ValidateForm() twice, as you are above. You can just do

if(!ValidateForm()){
..
} else ...

I think that will solve the issue as above it looks like your comparing true/false to the string equivalent 'false'.

In addition to the Wikipedia Cyclic redundancy check and Computation of CRC articles, I found a paper entitled Reversing CRC - Theory and Practice^* to be a good reference.

There are essentially three approaches for computing a CRC: an algebraic approach, a bit-oriented approach, and a table-driven approach. In Reversing CRC - Theory and Practice^*, each of these three algorithms/approaches is explained in theory accompanied in the APPENDIX by an implementation for the CRC32 in the C programming language.

You can use:

return View("../Category/NotFound", model);

It was tested in ASP.NET MVC 3, but should also work in ASP.NET MVC 2.

I was having some issues using the above solutions with an "associative array" type object. These solutions seem to preserve the values, but they do not preserve the actual names of the objects that those values are associated with, which can cause some issues. So I put together the following functions which I am using instead:

function flattenAssocArr(object) {
  if(typeof object == "object") {
    var keys = [];
    keys[0] = "ASSOCARR";
    keys.push(...Object.keys(object));
    var outArr = [];
    outArr[0] = keys;
    for(var i = 1; i < keys.length; i++) {
        outArr[i] = flattenAssocArr(object[keys[i]])
    }
    return outArr;
  } else {
    return object;
  }
}

function expandAssocArr(object) {
    if(typeof object !== "object")
        return object;
    var keys = object[0];
    var newObj = new Object();
    if(keys[0] === "ASSOCARR") {
        for(var i = 1; i < keys.length; i++) {
            newObj[keys[i]] = expandAssocArr(object[i])
        }
    }
    return newObj;
}

Note that these can't be used with any arbitrary object -- basically it creates a new array, stores the keys as element 0, with the data following it. So if you try to load an array that isn't created with these functions having element 0 as a key list, the results might be...interesting :)

I'm using it like this:

var objAsString = JSON.stringify(flattenAssocArr(globalDataset));
var strAsObject = expandAssocArr(JSON.parse(objAsString));

Neither one of GET and POST is inherently "more secure" than the other, just like neither one of fax and phone is "more secure" than the other. The various HTTP methods are provided so that you can choose the one which is most appropiate for the problem you're trying to solve. GET is more appropiate for idempotent queries while POST is more appropiate for "action" queries, but you can shoot yourself in the foot just as easily with any of them if you don't understand the security architecture for the application you're maintaining.

It's probably best if you read Chapter 9: Method Definitions of the HTTP/1.1 RFC to get an overall idea of what GET and POST were originally envisioned ot mean.

If you want to use them as in swift 2, you can use these funcs:

For CGRectMake:

func CGRectMake(_ x: CGFloat, _ y: CGFloat, _ width: CGFloat, _ height: CGFloat) -> CGRect {
    return CGRect(x: x, y: y, width: width, height: height)
}

For CGPointMake:

func CGPointMake(_ x: CGFloat, _ y: CGFloat) -> CGPoint {
    return CGPoint(x: x, y: y)
}

For CGSizeMake:

func CGSizeMake(_ width: CGFloat, _ height: CGFloat) -> CGSize {
    return CGSize(width: width, height: height)
}

Just put them outside any class and it should work. (Works for me at least)

Bring up the context menu (i.e. right click) in the source code window of the desired class. Then select the Source submenu; from that menu selecting Generate Getters and Setters... will cause a wizard window to appear.

Source -> Generate Getters and Setters...

Select the variables you wish to create getters and setters for and click OK.

Go to Project-><Projectname> Properties. Then click on the Debug tab, and fill in your arguments in the textbox called Command line arguments.

Another better option is to not depend on PRINT or RAISERROR and just load your "print" statements into a ##Temp table in TempDB or a permanent table in your database which will give you visibility to the data immediately via a SELECT statement from another window. This works the best for me. Using a permanent table then also serves as a log to what happened in the past. The print statements are handy for errors, but using the log table you can also determine the exact point of failure based on the last logged value for that particular execution (assuming you track the overall execution start time in your log table.)

The arrow operator is like dot, except it dereferences a pointer first. foo.bar() calls method bar() on object foo, foo->bar calls method bar on the object pointed to by pointer foo.

You can work with BigInteger like below example, most especially if you have 256 bit or longer:

String string = "10000010";
BigInteger biStr = new BigInteger(string, 2);

System.out.println("binary: " + biStr.toString(2));
System.out.println("hex: " + biStr.toString(16));
System.out.println("dec: " + biStr.toString(10));

Another example which accepts bytes:

String string = "The girl on the red dress.";

byte[] byteString = string.getBytes(Charset.forName("UTF-8"));
System.out.println("[Input String]: " + string);
System.out.println("[Encoded String UTF-8]: " + byteString);

BigInteger biStr = new BigInteger(byteString);
System.out.println("binary: " + biStr.toString(2)); // binary
System.out.println("hex: " + biStr.toString(16));   // hex or base 16
System.out.println("dec: " + biStr.toString(10));  // this is base 10

Result:

[Input String]: The girl on the red dress.
[Encoded String UTF-8]: [B@70dea4e

binary: 101010001101000011001010010000001100111011010010111001001101100001000000110111101101110001000000111010001101000011001010010000001110010011001010110010000100000011001000111001001100101011100110111001100101110
hex: 546865206769726c206f6e20746865207265642064726573732e

You can also work to convert Binary to Byte format

try {
   System.out.println("binary to byte: " + biStr.toString(2).getBytes("UTF-8"));
} catch (UnsupportedEncodingException e) {e.printStackTrace();}

Note: For string formatting for your Binary format you can use below sample

String.format("%256s", biStr.toString(2).replace(' ', '0'));  // this is for the 256 bit formatting

If this error occurs with the jdk use this :

progra~1 instead of program files in the path example :

 c:/progra~1/java instead of c:/program files/java

It will be ok always avoid space in java code.....

it can be used for every thing in program files, otherwise put quotes at the beginning and the en of path

"c:/..../"

std::chrono::time_point<std::chrono::system_clock> now = std::chrono::system_clock::now();

This is a great place for auto:

auto now = std::chrono::system_clock::now();

Since you want to traffic at millisecond precision, it would be good to go ahead and covert to it in the time_point:

auto now_ms = std::chrono::time_point_cast<std::chrono::milliseconds>(now);

now_ms is a time_point, based on system_clock, but with the precision of milliseconds instead of whatever precision your system_clock has.

auto epoch = now_ms.time_since_epoch();

epoch now has type std::chrono::milliseconds. And this next statement becomes essentially a no-op (simply makes a copy and does not make a conversion):

auto value = std::chrono::duration_cast<std::chrono::milliseconds>(epoch);

Here:

long duration = value.count();

In both your and my code, duration holds the number of milliseconds since the epoch of system_clock.

This:

std::chrono::duration<long> dur(duration);

Creates a duration represented with a long, and a precision of seconds. This effectively reinterpret_casts the milliseconds held in value to seconds. It is a logic error. The correct code would look like:

std::chrono::milliseconds dur(duration);

This line:

std::chrono::time_point<std::chrono::system_clock> dt(dur);

creates a time_point based on system_clock, with the capability of holding a precision to the system_clock's native precision (typically finer than milliseconds). However the run-time value will correctly reflect that an integral number of milliseconds are held (assuming my correction on the type of dur).

Even with the correction, this test will (nearly always) fail though:

if (dt != now)

Because dt holds an integral number of milliseconds, but now holds an integral number of ticks finer than a millisecond (e.g. microseconds or nanoseconds). Thus only on the rare chance that system_clock::now() returned an integral number of milliseconds would the test pass.

But you can instead:

if (dt != now_ms)

And you will now get your expected result reliably.

Putting it all together:

int main ()
{
    auto now = std::chrono::system_clock::now();
    auto now_ms = std::chrono::time_point_cast<std::chrono::milliseconds>(now);

    auto value = now_ms.time_since_epoch();
    long duration = value.count();

    std::chrono::milliseconds dur(duration);

    std::chrono::time_point<std::chrono::system_clock> dt(dur);

    if (dt != now_ms)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

Personally I find all the std::chrono overly verbose and so I would code it as:

int main ()
{
    using namespace std::chrono;
    auto now = system_clock::now();
    auto now_ms = time_point_cast<milliseconds>(now);

    auto value = now_ms.time_since_epoch();
    long duration = value.count();

    milliseconds dur(duration);

    time_point<system_clock> dt(dur);

    if (dt != now_ms)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

Which will reliably output:

Success.

Finally, I recommend eliminating temporaries to reduce the code converting between time_point and integral type to a minimum. These conversions are dangerous, and so the less code you write manipulating the bare integral type the better:

int main ()
{
    using namespace std::chrono;
    // Get current time with precision of milliseconds
    auto now = time_point_cast<milliseconds>(system_clock::now());
    // sys_milliseconds is type time_point<system_clock, milliseconds>
    using sys_milliseconds = decltype(now);
    // Convert time_point to signed integral type
    auto integral_duration = now.time_since_epoch().count();
    // Convert signed integral type to time_point
    sys_milliseconds dt{milliseconds{integral_duration}};
    // test
    if (dt != now)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

The main danger above is not interpreting integral_duration as milliseconds on the way back to a time_point. One possible way to mitigate that risk is to write:

    sys_milliseconds dt{sys_milliseconds::duration{integral_duration}};

This reduces risk down to just making sure you use sys_milliseconds on the way out, and in the two places on the way back in.

And one more example: Let's say you want to convert to and from an integral which represents whatever duration system_clock supports (microseconds, 10^th of microseconds or nanoseconds). Then you don't have to worry about specifying milliseconds as above. The code simplifies to:

int main ()
{
    using namespace std::chrono;
    // Get current time with native precision
    auto now = system_clock::now();
    // Convert time_point to signed integral type
    auto integral_duration = now.time_since_epoch().count();
    // Convert signed integral type to time_point
    system_clock::time_point dt{system_clock::duration{integral_duration}};
    // test
    if (dt != now)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

This works, but if you run half the conversion (out to integral) on one platform and the other half (in from integral) on another platform, you run the risk that system_clock::duration will have different precisions for the two conversions.

AndroidStudio is alpha version for now. So you have to edit gradle build script files by yourself. Add next lines to your build.gradle

android {

    signingConfigs {

        release {

            storeFile file('android.keystore')
            storePassword "pwd"
            keyAlias "alias"
            keyPassword "pwd"
        }
    }

    buildTypes {

       release {

           signingConfig signingConfigs.release
       }
    }
}

To actually run your application at emulator or device run gradle installDebug or gradle installRelease.

You can create helloworld project from AndroidStudio wizard to see what structure of gradle files is needed. Or export gradle files from working eclipse project. Also this series of articles are helpfull http://blog.stylingandroid.com/archives/1872#more-1872

The ng-options directive does not set the value attribute on the <options> elements for arrays:

Using limit.value as limit.text for limit in limits means:

set the <option>'s label as limit.text
save the limit.value value into the select's ng-model
