Another way is to tell the marshaller to always use a certain prefix

marshaller.setProperty("com.sun.xml.bind.namespacePrefixMapper", new NamespacePrefixMapper() {
             @Override
            public String getPreferredPrefix(String arg0, String arg1, boolean arg2) {
                return "ns1";
            }
        });'

Hope it helps!

I extended Carlos LM's solution a bit so it's more detailed.

Example of a schema:

var schema = {
    _id: 123,
    id: 12,
    t: 'title',
    p: 4.5,
    ls: [{
            l: 'lemma',
            p: {
                pp: 8.9
            }
        },
         {
            l: 'lemma2',
            p: {
               pp: 8.3
           }
        }
    ]
};

Type into the console:

var schemafy = function(schema, i, limit) {
    var i = (typeof i !== 'undefined') ? i : 1;
    var limit = (typeof limit !== 'undefined') ? limit : false;
    var type = '';
    var array = false;

    for (key in schema) {
        type = typeof schema[key];
        array = (schema[key] instanceof Array) ? true : false;

        if (type === 'object') {
            print(Array(i).join('    ') + key+' <'+((array) ? 'array' : type)+'>:');
            schemafy(schema[key], i+1, array);
        } else {
            print(Array(i).join('    ') + key+' <'+type+'>');
        }

        if (limit) {
            break;
        }
    }
}

Run:

schemafy(db.collection.findOne());

Output

_id <number>
id <number>
t <string>
p <number>
ls <object>:
    0 <object>:
    l <string>
    p <object>:
        pp <number> 

Follow these steps to reset password in Windows system

1. Stop Mysql service from task manager

2. Create a text file and paste the below statement

MySQL 5.7.5 and earlier:

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('yournewpassword');

MySQL 5.7.6 and later:

ALTER USER 'root'@'localhost' IDENTIFIED BY 'yournewpassword';

3. Save as mysql-init.txt and place it in 'C' drive.

4. Open command prompt and paste the following

C:\> mysqld --init-file=C:\\mysql-init.txt

You would certainly benefit from using a responsive framework for your project. It would save you a good amount of headaches. However, seeing the structure of your HTML I would do the following:

Please check the example: http://jsfiddle.net/xLA4q/

HTML:

<div class="nav-content-wrapper">
 <div class="left-nav">asdasdasd ads asd ads asd ad asdasd ad ad a ad</div>
 <div class="content">asd as dad ads ads ads ad ads das ad sad</div>
</div>

CSS:

.nav-content-wrapper{position:relative; overflow:auto; display:block;height:300px;}
.left-nav{float:left;width:30%;height:inherit;}
.content{float:left;width:70%;height:inherit;}

I also face the same issue "OpenCV NoneType object has no attribute shape" and i solve this by changing the image location. I also use the PyCharm IDE. Currently my image location and class file in the same folder.

The traditional for loop in Objective-C is inherited from standard C and takes the following form:

for (/* Instantiate local variables*/ ; /* Condition to keep looping. */ ; /* End of loop expressions */)
{
    // Do something.
}

For example, to print the numbers from 1 to 10, you could use the for loop:

for (int i = 1; i <= 10; i++)
{
    NSLog(@"%d", i);
}

On the other hand, the for in loop was introduced in Objective-C 2.0, and is used to loop through objects in a collection, such as an NSArray instance. For example, to loop through a collection of NSString objects in an NSArray and print them all out, you could use the following format.

for (NSString* currentString in myArrayOfStrings)
{
    NSLog(@"%@", currentString);
}

This is logically equivilant to the following traditional for loop:

for (int i = 0; i < [myArrayOfStrings count]; i++)
{
    NSLog(@"%@", [myArrayOfStrings objectAtIndex:i]);
}

The advantage of using the for in loop is firstly that it's a lot cleaner code to look at. Secondly, the Objective-C compiler can optimize the for in loop so as the code runs faster than doing the same thing with a traditional for loop.

Hope this helps.

Use $http_MY_CUSTOM_HEADER

You can write some-thing like

set my_header $http_MY_CUSTOM_HEADER;
if($my_header != 'some-value') {
#do some thing;
}

In a standard context, each connected user holds an explorer.exe process: The command [tasklist /V|find "explorer"] returns a line that contains the explorer.exe process owner's, with an adapted regex it is possible to obtain the required value. This also runs perfectly under Windows 7.

In rare cases explorer.exe is replaced by another program, the find filter can be adapted to match this case. If the command return an empty line then it is likely that no user is logged on. With Windows 7 it is also possible to run [query session|find ">"].

Use the return keyword.

From MSDN:

The return statement terminates execution of the method in which it appears and returns control to the calling method. It can also return the value of the optional expression. If the method is of the type void, the return statement can be omitted.

So in your case, the usage would be:

private void button1_Click(object sender, EventArgs e)
{
    if (textBox1.Text == "" || textBox2.Text == "" || textBox3.Text == "")
    {
        return; //exit this event
    }
}

yes, static block is used for initialize the code and it will load at the time JVM start for execution.

static block is used in previous versions of java but in latest version it doesn't work.

I realize this question was asked a long time ago, but I came here looking for answers and wasn't satisfied with anything I could find. I finally found the answer here:

https://www.tutorialsteacher.com/mvc/htmlhelper-dropdownlist-dropdownlistfor

To get the results from the form, use the FormCollection and then pull each individual value out by it's model name thus:

yourRecord.FieldName = Request.Form["FieldNameInModel"];

As far as I could tell it makes absolutely no difference what argument name you give to the FormCollection - use Request.Form["NameFromModel"] to retrieve it.

No, I did not dig down to see how th4e magic works under the covers. I just know it works...

I hope this helps somebody avoid the hours I spent trying different approaches before I got it working.

You could use iotop. It doesn't rely on a kernel patch. It Works with stock Ubuntu kernel

There is a package for it in the Ubuntu repos. You can install it using

sudo apt-get install iotop

string.join the list values separated by commas, and use the format operator to form a query string.

myquery = "select name from studens where id in (%s)" % ",".join(map(str,mylist))

(Thanks, blair-conrad)

Try this:

schtasks /change /ENABLE /tn "Auto Restart" /s mycomutername /u mycomputername\username/p mypassowrd

You don't need jquery, just use yourstring.length. See reference here and also here.

Update:

To support unicode strings, length need to be computed as following:

[...""].length

or create an auxiliary function

function uniLen(s) {
    return [...s].length
}

I set my "iOS Deployment Target" in "Project" and "Targets" from 7.1 to 8.0 and restarted Xcode (with "Quit") and it worked.

You don't need JavaScript for this. Just wanted to make that clear, since as of the time this answer was posted, all of the answers to this question involve the use of JavaScript in some way or another.

You can do this rather easily with pure HTML and CSS by creating a form with hidden fields containing the data you want to submit, then styling the submit button of the form to look like a link.

For example:

.inline {_x000D_
  display: inline;_x000D_
}_x000D_
_x000D_
.link-button {_x000D_
  background: none;_x000D_
  border: none;_x000D_
  color: blue;_x000D_
  text-decoration: underline;_x000D_
  cursor: pointer;_x000D_
  font-size: 1em;_x000D_
  font-family: serif;_x000D_
}_x000D_
.link-button:focus {_x000D_
  outline: none;_x000D_
}_x000D_
.link-button:active {_x000D_
  color:red;_x000D_
}

<a href="some_page">This is a regular link</a>_x000D_
_x000D_
<form method="post" action="some_page" class="inline">_x000D_
  <input type="hidden" name="extra_submit_param" value="extra_submit_value">_x000D_
  <button type="submit" name="submit_param" value="submit_value" class="link-button">_x000D_
    This is a link that sends a POST request_x000D_
  </button>_x000D_
</form>

The exact CSS you use may vary depending on how regular links on your site are styled.

You may group your library.available_until wheres area by grouping method of Codeigniter for without disable escaping where clauses.

$this->db
    ->select('*')
    ->from('library')
    ->where('library.rating >=', $form['slider'])
    ->where('library.votes >=', '1000')
    ->where('library.language !=', 'German')
    ->group_start() //this will start grouping
    ->where('library.available_until >=', date("Y-m-d H:i:s"))
    ->or_where('library.available_until =', "00-00-00 00:00:00")
    ->group_end() //this will end grouping
    ->where('library.release_year >=', $year_start)
    ->where('library.release_year <=', $year_end)
    ->join('rating_repo', 'library.id = rating_repo.id')

Reference: https://www.codeigniter.com/userguide3/database/query_builder.html#query-grouping

If this is ASP.net-Core then you are mixing web API versions. Have the action return a derived IActionResult because in your current code the framework is treating HttpResponseMessage as a model.

[Route("api/[controller]")]
public class DownloadController : Controller {
    //GET api/download/12345abc
    [HttpGet("{id}"]
    public async Task<IActionResult> Download(string id) {
        Stream stream = await {{__get_stream_based_on_id_here__}}

        if(stream == null)
            return NotFound(); // returns a NotFoundResult with Status404NotFound response.

        return File(stream, "application/octet-stream"); // returns a FileStreamResult
    }    
}

#include <stdio.h>
#include <string.h>

int main ()
{
    char buf[] ="abc/qwe/ccd";
    int i = 0;
    char *p = strtok (buf, "/");
    char *array[3];

    while (p != NULL)
    {
        array[i++] = p;
        p = strtok (NULL, "/");
    }

    for (i = 0; i < 3; ++i) 
        printf("%s\n", array[i]);

    return 0;
}

You can find those maven properties in the super pom.

You find the jar here:

${M2_HOME}/lib/maven-model-builder-3.0.3.jar

Open the jar with 7-zip or some other archiver (or use the jar tool).

Navigate to

org/apache/maven/model

There you'll find the pom-4.0.0.xml.

It contains all those "short cuts":

<project>
    ...
    <build>
        <directory>${project.basedir}/target</directory>
        <outputDirectory>${project.build.directory}/classes</outputDirectory>
        <finalName>${project.artifactId}-${project.version}</finalName>
        <testOutputDirectory>${project.build.directory}/test-classes</testOutputDirectory>
        <sourceDirectory>${project.basedir}/src/main/java</sourceDirectory>
        <scriptSourceDirectory>src/main/scripts</scriptSourceDirectory>
        <testSourceDirectory>${project.basedir}/src/test/java</testSourceDirectory>
        <resources>
            <resource>
                <directory>${project.basedir}/src/main/resources</directory>
            </resource>
        </resources>
        <testResources>
            <testResource>
                <directory>${project.basedir}/src/test/resources</directory>
            </testResource>
        </testResources>
        ...
    </build>
    ...
</project>

Update

After some lobbying I am adding a link to the pom-4.0.0.xml. This allows you to see the properties without opening up the local jar file.

1. UNIQUE constraint (of which a PRIMARY KEY constraint is a variant). Checks that all values of a given field are unique across the table. This is X-axis constraint (records)

2. CHECK constraint (of which a NOT NULL constraint is a variant). Checks that a certain condition holds for the expression over the fields of the same record. This is Y-axis constraint (fields)

3. FOREIGN KEY constraint. Checks that a field's value is found among the values of a field in another table. This is Z-axis constraint (tables).

Use $dec = $null

From the documentation:

$null is an automatic variable that contains a NULL or empty value. You can use this variable to represent an absent or undefined value in commands and scripts.

PowerShell treats $null as an object with a value, that is, as an explicit placeholder, so you can use $null to represent an empty value in a series of values.

The following solution should work quite well for what you are trying to do.

1. The JavaScript block is placed very late in the document so you don't have to worry about elements not existing.

2. You are setting a PHP variable at the top of the script and outputting just the value of the variable within the JavaScript block.

   This way, you don't have to worry about escaping double-quotes or HEREDOCS (which is the recommended method if you REALLY must go there).

   Javascript Embedding Example

   <div id="helloContainer"><div>
   
   <script type="text/javascript">
       document.getElementById('helloContainer').innerHTML = '<?= $greeting; ?>';
   </script>
   

You can apply a reset css to get rid of those 'defaults'. Here is an example of a reset css http://meyerweb.com/eric/tools/css/reset/ . Just apply the reset styles BEFORE your own styles.

If your numbers are a, b and c then:

    int a = 1;
    int b = 2;
    int c = 3;

    int d =  a > b ? a : b;
    return c > d ? c : d;

This could turn into one of those "how many different ways can we do this" type questions!

You can get width and height of image with BufferedImage object using java.

public void setWidthAndHeightImage(FileUploadEvent event){
    byte[] imageTest = event.getFile().getContents();
                baiStream = new ByteArrayInputStream(imageTest );
                BufferedImage bi = ImageIO.read(baiStream);
                //get width and height of image
                int imageWidth = bi.getWidth();
                int imageHeight = bi.getHeight();
    }

Png files can handle transparency. So you could use this question Save plot to image file instead of displaying it using Matplotlib so as to save you graph as a png file.

And if you want to turn all white pixel transparent, there's this other question : Using PIL to make all white pixels transparent?

If you want to turn an entire area to transparent, then there's this question: And then use the PIL library like in this question Python PIL: how to make area transparent in PNG? so as to make your graph transparent.

If you're using PHP, I recommend using the PHP SDK for Firebase: Firebase Admin SDK. For an easy configuration you can follow these steps:

Get the project credentials json file from Firebase (Initialize the sdk) and include it in your project.

Install the SDK in your project. I use composer:

composer require kreait/firebase-php ^4.35

Try any example from the Cloud Messaging session in the SDK documentation:

use Kreait\Firebase;
use Kreait\Firebase\Messaging\CloudMessage;

$messaging = (new Firebase\Factory())
->withServiceAccount('/path/to/firebase_credentials.json')
->createMessaging();

$message = CloudMessage::withTarget(/* see sections below */)

    ->withData(['key' => 'value']);

$messaging->send($message);

Yes. You can pass the numerical values to the constructor for the enum, like so:

enum Ids {
  OPEN(100),
  CLOSE(200);

  private int value;    

  private Ids(int value) {
    this.value = value;
  }

  public int getValue() {
    return value;
  }
}

See the Sun Java Language Guide for more information.

ListView myListView = (ListView) rootView.findViewById(R.id.myListView);
ArrayList<String> myStringArray1 = new ArrayList<String>();
myStringArray1.add("something");
adapter = new CustomAdapter(getActivity(), R.layout.row, myStringArray1);
myListView.setAdapter(adapter);

Try it like this

public OnClickListener moreListener = new OnClickListener() {

    @Override
    public void onClick(View v) {
        adapter = null;
        myStringArray1.add("Andrea");
        adapter = new CustomAdapter(getActivity(), R.layout.row, myStringArray1);
        myListView.setAdapter(adapter);
        adapter.notifyDataSetChanged();
    }       
};

You can use javascript's indexOf function.

var str1 = "ABCDEFGHIJKLMNOP";_x000D_
var str2 = "DEFG";_x000D_
if(str1.indexOf(str2) != -1){_x000D_
    console.log(str2 + " found");_x000D_
}

its work short code

$('.SeeMore2').click(function(){ var $this = $(this).toggleClass('SeeMore2'); if($(this).hasClass('SeeMore2')) { $(this).text('See More');
} else { $(this).text('See Less'); } });

My worry is if I say delete evertything with an ID (>79 AND < 296) then it may literally wipe the whole table...

That wont happen because you will have a where clause. What happens is that, if you have a statement like delete * from Table1 where id between 70 and 1296 , the first thing that sql query processor will do is to scan the table and look for those records in that range and then apply a delete.

You Can Go To setting > editor > general > code folding and check "show code folding outline" .

Simply call

print(unknownDataType.runtimeType)

on the data.

If you guys are facing "Permission Denial: starting Intent..." error or if the app is getting crash without any reason during launching the app - Then use this single line code in Manifest

android:exported="true"

Please be careful with finish(); , if you missed out it the app getting frozen. if its mentioned the app would be a smooth launcher.

finish();

The other solution only works for two activities that are in the same application. In my case, application B doesn't know class com.example.MyExampleActivity.class in the code, so compile will fail.

I searched on the web and found something like this below, and it works well.

Intent intent = new Intent();
intent.setComponent(new ComponentName("com.example", "com.example.MyExampleActivity"));
startActivity(intent);

You can also use the setClassName method:

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.hotfoot.rapid.adani.wheeler.android", "com.hotfoot.rapid.adani.wheeler.android.view.activities.MainActivity");
startActivity(intent);
finish();

You can also pass the values from one app to another app :

Intent launchIntent = getApplicationContext().getPackageManager().getLaunchIntentForPackage("com.hotfoot.rapid.adani.wheeler.android.LoginActivity");
if (launchIntent != null) {
    launchIntent.putExtra("AppID", "MY-CHILD-APP1");
    launchIntent.putExtra("UserID", "MY-APP");
    launchIntent.putExtra("Password", "MY-PASSWORD");
    startActivity(launchIntent);
    finish();
} else {
    Toast.makeText(getApplicationContext(), " launch Intent not available", Toast.LENGTH_SHORT).show();
}

If it is not feasable to use a map for finding items based on a key, you can consider the goderive tool. Goderive generates a type specific implementation of a contains method, making your code both readable and efficient.

Example;

type Foo struct {
    Field1 string
    Field2 int
} 

func Test(m Foo) bool {
     var allItems []Foo
     return deriveContainsFoo(allItems, m)
}

To generate the deriveContainsFoo method:

• Install goderive with go get -u github.com/awalterschulze/goderive
• Run goderive ./... in your workspace folder

This method will be generated for deriveContains:

func deriveContainsFoo(list []Foo, item Foo) bool {
    for _, v := range list {
        if v == item {
            return true
        }
    }
    return false
}

Goderive has support for quite some other useful helper methods to apply a functional programming style in go.

My solution, also quite simple..

$array = [...];
$last = count($array) - 1;

foreach($array as $index => $value) 
{
     if($index == $last)
        // this is last array
     else
        // this is not last array
}

In your action change ViewBag.countrydrop = item8 to ViewBag.country = item8;and in View write like this:

@Html.DropDownList("country",
                   (IEnumerable<SelectListItem>)ViewBag.country,
                   "Select country")

Actually when you write

@Html.DropDownList("country", (IEnumerable)ViewBag.country, "Select country")

or

Html.DropDownList("country","Select Country)

it looks in for IEnumerable<SelectListItem> in ViewBag with key country, you can also use this overload in this case:

@Html.DropDownList("country","Select country") // it will look for ViewBag.country and populates dropdown

See Working DEMO Example

The best solution for generating an SHA-1 key for Android is from Android Studio.

Click on Gradle on the far right side:

Click on the refresh icon, and you will see the name of the app:

Click on Tasks -> Report -> Signing Report:

Find the SHA-1 key on the bottom part in the console:

Try to turn off your firewall, it works for me. It seems that android studio wants to download some dependencies and our firewall prevents it from downloading it, just be aware that turning your firewall off may lower the security of your computer. If you have more time you can manually allow your android studio to bypass your firewall, this way you can turn on your firewall while allowing android studio to download anything that it wants.

public class TypedProperty<T> : Property
{
    public T TypedValue
    {
        get { return (T)(object)base.Value; }
        set { base.Value = value.ToString();}
    }
}

I using converting via an object. It is a little bit simpler.

in this scenario:

DELETE FROM tableA
WHERE (SELECT q.entitynum
FROM tableA q
INNER JOIN tableB u on (u.qlabel = q.entityrole AND u.fieldnum = q.fieldnum) 
WHERE (LENGTH(q.memotext) NOT IN (8,9,10) 
OR q.memotext NOT LIKE '%/%/%')
AND (u.FldFormat = 'Date'));

aren't you missing the column you want to compare to? example:

DELETE FROM tableA
WHERE entitynum in (SELECT q.entitynum
FROM tableA q
INNER JOIN tableB u on (u.qlabel = q.entityrole AND u.fieldnum = q.fieldnum) 
WHERE (LENGTH(q.memotext) NOT IN (8,9,10) 
OR q.memotext NOT LIKE '%/%/%')
AND (u.FldFormat = 'Date'));    

I assume it's that column since in your select statement you're selecting from the same table you're wanting to delete from with that column.

This Question is asked in Paytm interview for Java position. I come up with the following solution.

class ReverseStringWord{
public static void main(String[] args) {
    String s="My name is X Y Z";
    StringBuilder result=new StringBuilder();
    StringBuilder str=new StringBuilder();
    for(int i=0;i<s.length();i++){
        if(s.charAt(i)==' '){
            result.insert(0,str+" ");
            str.setLength(0);
        }
        else{
            str.append(s.charAt(i));
            if(i==s.length()-1){
                result.insert(0,str+" ");
            }
        }
    }
    System.out.println(result);
}}

Probably the fastest way is:

myString.All(c => char.IsDigit(c))

Note: it will return True in case your string is empty which is incorrect (if you not considering empty as valid number/digit )

if you have a dataframe where some columns are numeric and some are other (character or factor) and you only want to do the correlations for the numeric columns, you could do the following:

set.seed(10)

x = as.data.frame(matrix(rnorm(100), ncol = 10))
x$L1 = letters[1:10]
x$L2 = letters[11:20]

cor(x)

Error in cor(x) : 'x' must be numeric

but

cor(x[sapply(x, is.numeric)])

The accepted answer is helpful, but it isn't immediately obvious how to retrieve a filename from a path if you are NOT using passed in values. I was able to work this out from this thread, but in case others aren't so lucky, here is how it is done:

@echo off
setlocal enabledelayedexpansion enableextensions

set myPath=C:\Somewhere\Somewhere\SomeFile.txt
call :file_name_from_path result !myPath!
echo %result%
goto :eof

:file_name_from_path <resultVar> <pathVar>
(
    set "%~1=%~nx2"
    exit /b
)

:eof
endlocal

Now the :file_name_from_path function can be used anywhere to retrieve the value, not just for passed in arguments. This can be extremely helpful if the arguments can be passed into the file in an indeterminate order or the path isn't passed into the file at all.

My project was created using Visual Studio Community 2017 and it creates 3 separated modules: app.browser.module, app.server.module and app.shared.module

In order to create my components I checked above answers and found my module to be app.shared.module.

So, I run:

ng g c componentName --module=app.shared.module

As @Ian explained, the problem is that jQuery's click() is not the same as the native one.

Therefore, consider using vanilla-js instead of jQuery:

var a = document.createElement('a');
a.href = "img.png";
a.download = "output.png";
document.body.appendChild(a);
a.click();
document.body.removeChild(a);

Demo

Usually you don't have to worry about calculating them as your assembler (or linker) will take of getting the calculations right. Let's say you have a small function:

func:
  slti $t0, $a0, 2
  beq $t0, $zero, cont
  ori $v0, $zero, 1
  jr $ra
cont:
  ...
  jal func
  ... 

When translating the above code into a binary stream of instructions the assembler (or linker if you first assembled into an object file) it will be determined where in memory the function will reside (let's ignore position independent code for now). Where in memory it will reside is usually specified in the ABI or given to you if you're using a simulator (like SPIM which loads the code at 0x400000 - note the link also contains a good explanation of the process).

Assuming we're talking about the SPIM case and our function is first in memory, the slti instruction will reside at 0x400000, the beq at 0x400004 and so on. Now we're almost there! For the beq instruction the branch target address is that of cont (0x400010) looking at a MIPS instruction reference we see that it is encoded as a 16-bit signed immediate relative to the next instruction (divided by 4 as all instructions must reside on a 4-byte aligned address anyway).

That is:

Current address of instruction + 4 = 0x400004 + 4 = 0x400008
Branch target = 0x400010
Difference = 0x400010 - 0x400008 = 0x8
To encode = Difference / 4 = 0x8 / 4 = 0x2 = 0b10

Encoding of beq $t0, $zero, cont

0001 00ss ssst tttt iiii iiii iiii iiii
---------------------------------------
0001 0001 0000 0000 0000 0000 0000 0010

As you can see you can branch to within -0x1fffc .. 0x20000 bytes. If for some reason, you need to jump further you can use a trampoline (an unconditional jump to the real target placed placed within the given limit).

Jump target addresses are, unlike branch target addresses, encoded using the absolute address (again divided by 4). Since the instruction encoding uses 6 bits for the opcode, this only leaves 26 bits for the address (effectively 28 given that the 2 last bits will be 0) therefore the 4 bits most significant bits of the PC register are used when forming the address (won't matter unless you intend to jump across 256 MB boundaries).

Returning to the above example the encoding for jal func is:

Destination address = absolute address of func = 0x400000
Divided by 4 = 0x400000 / 4 = 0x100000
Lower 26 bits = 0x100000 & 0x03ffffff = 0x100000 = 0b100000000000000000000

0000 11ii iiii iiii iiii iiii iiii iiii
---------------------------------------
0000 1100 0001 0000 0000 0000 0000 0000

You can quickly verify this, and play around with different instructions, using this online MIPS assembler i ran across (note it doesn't support all opcodes, for example slti, so I just changed that to slt here):

00400000: <func>    ; <input:0> func:

I have had a similar issue in iOS 8, 9 and 10 and the info above couldn't fix it, however I did discover a solution after a day of working on this. Granted it won't work for everyone but in my case my items were stacked in a column and had 0 height when it should have been content height. Switching the css to be row and wrap fixed the issue. This only works if you have a single item and they are stacked but since it took me a day to find this out I thought I should share my fix!

.wrapper {
    flex-direction: column; // <-- Remove this line
    flex-direction: row; // <-- replace it with
    flex-wrap: wrap; // <-- Add wrapping
}

.item {
    width: 100%;
}

npm install --save express

This worked for me. Just run express.js installation again.

Groovy maps can be used with the property property, so you can just do:

def x = mymap.likes

If the key you are looking for (for example 'likes.key') contains a dot itself, then you can use the syntax:

def x = mymap.'likes.key'

Java Strings aren't character Iterable. You'll need:

for (int i = 0; i < examplestring.length(); i++) {
  char c = examplestring.charAt(i);
  ...
}

Awkward I know.

I'm always the one to bring up findall() =)

>>> strings = ['foofo21', 'bar432', 'foobar12345']
>>> [re.findall(r'(\w+?)(\d+)', s)[0] for s in strings]
[('foofo', '21'), ('bar', '432'), ('foobar', '12345')]

Note that I'm using a simpler (less to type) regex than most of the previous answers.

you can add it any where you want, when you run your project, configure the classpath and add the location of the log4j.properties files by clicking on: Run->Run Configuration -> [classpath tab] -> click on user Entries -> Advanced -> Select Add Folder -> select the location of your log4j.properties file

and then -> OK -> run

and it should get loaded

To avoid this sort of trouble, you can use replace (which takes a plain string) instead of replaceAll (which takes a regular expression). You will still need to escape backslashes, but not in the wild ways required with regular expressions.

pseudocode as I haven't got a java sdk on me:

Char candidates = new Char[] { 'A', 'B', ... 'G' };

foreach(Char c in candidates)
{
    if (symbol == c) { return true; }
}
return false;

You can need to pass in the string 'int64':

>>> import pandas as pd
>>> df = pd.DataFrame({'a': [1.0, 2.0]})  # some test dataframe

>>> df['a'].astype('int64')
0    1
1    2
Name: a, dtype: int64

There are some alternative ways to specify 64-bit integers:

>>> df['a'].astype('i8')      # integer with 8 bytes (64 bit)
0    1
1    2
Name: a, dtype: int64

>>> import numpy as np
>>> df['a'].astype(np.int64)  # native numpy 64 bit integer
0    1
1    2
Name: a, dtype: int64

Or use np.int64 directly on your column (but it returns a numpy.array):

>>> np.int64(df['a'])
array([1, 2], dtype=int64)

request.raw_post_data has been deprecated. Use request.body instead

Here's a simpler version in Java. It does use only two pointers curr & prev

public void reverse(Node head) {
    Node curr = head, prev = null;

    while (head.next != null) {
        head = head.next; // move the head to next node
        curr.next = prev; //break the link to the next node and assign it to previous
        prev = curr;      // we are done with previous, move it to next node
        curr = head;      // current moves along with head
    }

    head.next = prev;     //for last node
}

set the dll path in the config file

<add key="dllPath" value="C:\Users\UserName\YourApp\myLibFolder\myDLL.dll" />

before calling the dll in you app, do the following

string dllPath= ConfigurationManager.AppSettings["dllPath"];    
   string appDirectory = Path.GetDirectoryName(dllPath);
   Directory.SetCurrentDirectory(appDirectory);

then call the dll and you can use like below

 [DllImport("myDLL.dll", CallingConvention = CallingConvention.Cdecl)]
public static extern int DLLFunction(int Number1, int Number2);

You should look into Video For Everyone:

Video for Everybody is very simply a chunk of HTML code that embeds a video into a website using the HTML5 element which offers native playback in Firefox 3.5 and Safari 3 & 4 and an increasing number of other browsers.

The video is played by the browser itself. It loads quickly and doesn’t threaten to crash your browser.

In other browsers that do not support , it falls back to QuickTime.

If QuickTime is not installed, Adobe Flash is used. You can host locally or embed any Flash file, such as a YouTube video.

The only downside, is that you have to have 2/3 versions of the same video stored, but you can serve to every existing device/browser that supports video (i.e.: the iPhone).

Old question, but still relevant. Here is what worked for me today (6/26/16).

From the bash shell:

lynx -source rawgit.com/transcode-open/apt-cyg/master/apt-cyg > apt-cyg
install apt-cyg /bin

Here is what I'm using to have this be a constant expression, if the input is a constant expression.

#define uptopow2_0(v) ((v) - 1)
#define uptopow2_1(v) (uptopow2_0(v) | uptopow2_0(v) >> 1)
#define uptopow2_2(v) (uptopow2_1(v) | uptopow2_1(v) >> 2)
#define uptopow2_3(v) (uptopow2_2(v) | uptopow2_2(v) >> 4)
#define uptopow2_4(v) (uptopow2_3(v) | uptopow2_3(v) >> 8)
#define uptopow2_5(v) (uptopow2_4(v) | uptopow2_4(v) >> 16)

#define uptopow2(v) (uptopow2_5(v) + 1)  /* this is the one programmer uses */

So for instance, an expression like:

uptopow2(sizeof (struct foo))

will nicely reduce to a constant.

In case you get "Unable to locate tools.jar. Expected to find it in C:\Program Files (x86)\Java\jre6\lib\tools.jar" you can add an environment variable JAVA_HOME that points to your Java JDK path, for example c:\sdks\glassfish3\jdk (restart MSVC afterwards)

An even better solution is using WinGDB Mobile Edition in Visual Studio: it lets you create and debug Android projects all inside Visual Studio:

You'd probably use the subprocess module. Something like this:

import subprocess
p = subprocess.Popen(["scp", myfile, destination])
sts = os.waitpid(p.pid, 0)

Where destination is probably of the form user@remotehost:remotepath. Thanks to @Charles Duffy for pointing out the weakness in my original answer, which used a single string argument to specify the scp operation shell=True - that wouldn't handle whitespace in paths.

The module documentation has examples of error checking that you may want to perform in conjunction with this operation.

Ensure that you've set up proper credentials so that you can perform an unattended, passwordless scp between the machines. There is a stackoverflow question for this already.

All that's needed is that the format specifiers and the types agree, and you can always cast to make that true. long is at least 32 bits, so %lu together with (unsigned long)k is always correct:

uint32_t k;
printf("%lu\n", (unsigned long)k);

size_t is trickier, which is why %zu was added in C99. If you can't use that, then treat it just like k (long is the biggest type in C89, size_t is very unlikely to be larger).

size_t sz;
printf("%zu\n", sz);  /* C99 version */
printf("%lu\n", (unsigned long)sz);  /* common C89 version */

If you don't get the format specifiers correct for the type you are passing, then printf will do the equivalent of reading too much or too little memory out of the array. As long as you use explicit casts to match up types, it's portable.

There is a library which allows you to use HttpClient with strongly-typed callbacks.

The data and the error are available directly via these callbacks.

When you use HttpClient with Observable, you have to use .subscribe(x=>...) in the rest of your code.

This is because Observable<HttpResponse<T>> is tied to HttpResponse.

This tightly couples the http layer with the rest of your code.

This library encapsulates the .subscribe(x => ...) part and exposes only the data and error through your Models.

With strongly-typed callbacks, you only have to deal with your Models in the rest of your code.

The library is called angular-extended-http-client.

angular-extended-http-client library on GitHub

angular-extended-http-client library on NPM

Very easy to use.

Sample usage

The strongly-typed callbacks are

Success:

• IObservable<T>
• IObservableHttpResponse
• IObservableHttpCustomResponse<T>

Failure:

• IObservableError<TError>
• IObservableHttpError
• IObservableHttpCustomError<TError>

Add package to your project and in your app module

import { HttpClientExtModule } from 'angular-extended-http-client';

and in the @NgModule imports

  imports: [
    .
    .
    .
    HttpClientExtModule
  ],

Your Models

//Normal response returned by the API.
export class RacingResponse {
    result: RacingItem[];
}

//Custom exception thrown by the API.
export class APIException {
    className: string;
}

Your Service

In your Service, you just create params with these callback types.

Then, pass them on to the HttpClientExt's get method.

import { Injectable, Inject } from '@angular/core'
import { RacingResponse, APIException } from '../models/models'
import { HttpClientExt, IObservable, IObservableError, ResponseType, ErrorType } from 'angular-extended-http-client';
.
.

@Injectable()
export class RacingService {

    //Inject HttpClientExt component.
    constructor(private client: HttpClientExt, @Inject(APP_CONFIG) private config: AppConfig) {

    }

    //Declare params of type IObservable<T> and IObservableError<TError>.
    //These are the success and failure callbacks.
    //The success callback will return the response objects returned by the underlying HttpClient call.
    //The failure callback will return the error objects returned by the underlying HttpClient call.
    getRaceInfo(success: IObservable<RacingResponse>, failure?: IObservableError<APIException>) {
        let url = this.config.apiEndpoint;

        this.client.get(url, ResponseType.IObservable, success, ErrorType.IObservableError, failure);
    }
}

Your Component

In your Component, your Service is injected and the getRaceInfo API called as shown below.

  ngOnInit() {    
    this.service.getRaceInfo(response => this.result = response.result,
                                error => this.errorMsg = error.className);

  }

Both, response and error returned in the callbacks are strongly typed. Eg. response is type RacingResponse and error is APIException.

You only deal with your Models in these strongly-typed callbacks.

Hence, The rest of your code only knows about your Models.

Also, you can still use the traditional route and return Observable<HttpResponse<T>> from Service API.

MD5 is perfectly fine if you don't need the best security, and if you're doing something like checking file integrity then security is not a consideration. In such as case you might want to consider something simpler and faster, such as Adler32, which is also supported by the Java libraries.

In particular, Nate’s answer, zfy’s answer, and Pradi’s answer are great.

In simpler terms, biases allow for more and more variations of weights to be learnt/stored... (side-note: sometimes given some threshold). Anyway, more variations mean that biases add richer representation of the input space to the model's learnt/stored weights. (Where better weights can enhance the neural net’s guessing power)

For example, in learning models, the hypothesis/guess is desirably bounded by y=0 or y=1 given some input, in maybe some classification task... i.e some y=0 for some x=(1,1) and some y=1 for some x=(0,1). (The condition on the hypothesis/outcome is the threshold I talked about above. Note that my examples setup inputs X to be each x=a double or 2 valued-vector, instead of Nate's single valued x inputs of some collection X).

If we ignore the bias, many inputs may end up being represented by a lot of the same weights (i.e. the learnt weights mostly occur close to the origin (0,0). The model would then be limited to poorer quantities of good weights, instead of the many many more good weights it could better learn with bias. (Where poorly learnt weights lead to poorer guesses or a decrease in the neural net’s guessing power)

So, it is optimal that the model learns both close to the origin, but also, in as many places as possible inside the threshold/decision boundary. With the bias we can enable degrees of freedom close to the origin, but not limited to origin's immediate region.

1. Create folder assets in Project -> app (or your app name) -> src -> main -> right click -> New -> Directory.
2. Then create a new directory inside assets called "fonts".

To assign the font to the textView:

TextView textView = (TextView) findViewById(R.id.your_textView);

final Typeface font = Typeface.createFromAsset(context.getAssets(), "fonts/your_font_name");

your_font_name includes font extension.

Found it. System property 'java.home' is not JAVA_HOME environment variable. JAVA_HOME points to the JDK, while java.home points to the JRE. See that page for more info.

Soo... My problem was that my startpoint was the jre folder (C:\jdk1.6.0_26\jre) and not the jdk folder (C:\jdk1.6.0_26) as I thought(tools.jar is on the C:\jdk1.6.0_26\lib folder ). The compile line in dependencies.gradle should be:

compile files("${System.properties['java.home']}/../lib/tools.jar")

way mentioned by @dirkgently ( v.begin() + index ) nice and fast for vectors

but std::advance( v.begin(), index ) most generic way and for random access iterators works constant time too.

EDIT
differences in usage:

std::vector<>::iterator it = ( v.begin() + index );

or

std::vector<>::iterator it = v.begin();
std::advance( it, index );

added after @litb notes.

Get at number:

window.getComputedStyle( *Element* , null).getPropertyValue( *CSS* );

Example:

window.getComputedStyle( document.body ,null).getPropertyValue('background-color');  
window.getComputedStyle( document.body ,null).getPropertyValue('width');  
~ document.body.clientWidth

Listview derives from listbox control. One most important difference is listview uses the extended selection mode by default . listview also adds a property called view which enables you to customize the view in a richer way than a custom itemspanel. One real life example of listview with gridview is file explorer's details view. Listview with grid view is a less powerful data grid. After the introduction of datagrid control listview lost its importance.

This simplifies it a bit and it behaves as you want it.

FileWriter f = new FileWriter("../playlist/"+existingPlaylist.getText()+".txt");

try {
 f.write(source);
 ...
} catch(...) {
} finally {
 //close it here

Use distinct-colors.

It generates a palette of visually distinct colors.

distinct-colors is highly configurable:

• Choose how many colors are in the palette
• Restrict the hue to a specific range
• Restrict the chroma (saturation) to a specific range
• Restrict the lightness to a specific range
• Configure general quality of the palette

If you just want to change file permissions, you want to be careful about using -R on chmod since it will change anything, files or folders. If you are doing a relative change (like adding write permission for everyone), you can do this:

sudo chmod -R a+w /var/www

But if you want to use the literal permissions of read/write, you may want to select files versus folders:

sudo find /var/www -type f -exec chmod 666 {} \;

(Which, by the way, for security reasons, I wouldn't recommend either of these.)

Or for folders:

sudo find /var/www -type d -exec chmod 755 {} \;

Here's a performance comparison of the two. HTTP is more responsive for request-response of small files, but FTP may be better for large files if tuned properly. FTP used to be generally considered faster. FTP requires a control channel and state be maintained besides the TCP state but HTTP does not. There are 6 packet transfers before data starts transferring in FTP but only 4 in HTTP.

I think a properly tuned TCP layer would have more effect on speed than the difference between application layer protocols. The Sun Blueprint Understanding Tuning TCP has details.

Heres another good comparison of individual characteristics of each protocol.

Well, If you really want to do it in your DB there is a more accurate way as given in MSDN:

SET STATISTICS TIME ON

You can read this information from your application as well.

You'll need to check the contents of $_POST["JSONfullInfoArray"]. If something doesn't parse json_decode will just return null. This isn't very helpful so when null is returned you should check json_last_error() to get more info on what went wrong.

The data-* attributes is used to store custom data private to the page or application

So Bootstrap uses these attributes for saving states of objects

W3School data-* description

If you like fun, then you can just go to the listing page of you branches (for example merged) and just run in the javascript console:

document.querySelectorAll('tr td div a:first-child').forEach(function(item) { fetch('https://bitbucket.org/snippets/new?owner=<yourprofilenick>', {'credentials': 'same-origin'}).then((response) => {return response.text()}).then(function(string) { return /'csrfmiddlewaretoken' value='(.*)'/g.exec(string)[1] }).then(function(csrf) { if (!~item.innerText.indexOf('/')) return; 
 fetch(`https://bitbucket.org/!api/2.0/repositories/<your_organization_path>/refs/branches/${item.innerText}`, {headers: {"x-csrftoken": csrf}, credentials: "same-origin", method: 'DELETE'}).then(() => console.log(`${item.innerText} DELETED!`)) }) })

BEFORE RUN

• replace <yourprofilenick> with your BitBucket nick
• replace <your_organization_path> with your organization path

HOW IT WORKS

First we need a page with with a CSRF token in the page source, so I choose:

https://bitbucket.org/snippets/new?owner=<yourprofilenick>

Then for each branch (in a branch listing) it gets CSRF token and deletes that branch.

BEWARE

Remeber to prevent sensitive branches before deleting in repo settings.

It WON'T delete the main branch.

ADDITIONAL INFO

You have to be logged in.

It deletes only branches visible on that page (so to delete the rest of branches you have to go to the next page).

You can use scope_identity() to select the ID of the row you just inserted into a variable then just select whatever columns you want from that table where the id = the identity you got from scope_identity()

<ul>
    <li ng-repeat="item in filteredItems  = (items | filter:keyword)">
        ...
    </li>
</ul>
<div ng-hide="filteredItems.length">No items found</div>

• know the basic working of the .Net runtime
• know and understand the core parts of the .Net class libraries

from pyspark.sql.types import IntegerType
data_df = data_df.withColumn("Plays", data_df["Plays"].cast(IntegerType()))

You can run loop for each column but this is the simplest way to convert string column into integer.

We moved our department's build chain to CMake, and we had a few internal roadbumps since other departments where using our project files and where accustomed to just importing them into their solutions. We also had some complaints about CMake not being fully integrated into the Visual Studio project/solution manager, so files had to be added manually to CMakeLists.txt; this was a major break in the workflow people were used to.

But in general, it was a quite smooth transition. We're very happy since we don't have to deal with project files anymore.

The concrete workflow for adding a new file to a project is really simple:

1. Create the file, make sure it is in the correct place.
2. Add the file to CMakeLists.txt.
3. Build.

CMake 2.6 automatically reruns itself if any CMakeLists.txt files have changed (and (semi-)automatically reloads the solution/projects).

Remember that if you're doing out-of-source builds, you need to be careful not to create the source file in the build directory (since Visual Studio only knows about the build directory).

This example get token thouth HttpWebRequest

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(pathapi);
        request.Method = "POST";
        string postData = "grant_type=password";
        ASCIIEncoding encoding = new ASCIIEncoding();
        byte[] byte1 = encoding.GetBytes(postData);

        request.ContentType = "application/x-www-form-urlencoded";

        request.ContentLength = byte1.Length;
        Stream newStream = request.GetRequestStream();
        newStream.Write(byte1, 0, byte1.Length);

        HttpWebResponse response = request.GetResponse() as HttpWebResponse;            
        using (Stream responseStream = response.GetResponseStream())

Firstly, the Django docs strongly recommend not using NULL values for string-based fields such as CharField or TextField. Read the documentation for the explanation:

https://docs.djangoproject.com/en/dev/ref/models/fields/#null

Solution: You can also chain together methods on QuerySets, I think. Try this:

Name.objects.exclude(alias__isnull=True).exclude(alias="")

That should give you the set you're looking for.

Perhaps the easiest way is to just create a new repository with current state of the working copy. If you want to keep all the commit messages you could first do git log > original.log and then edit that for your initial commit message in the new repository:

rm -rf .git
git init
git add .
git commit

or

git log > original.log
# edit original.log as desired
rm -rf .git
git init
git add .
git commit -F original.log

I would say to add a paragraph with a period in it and style it like so:

<p class="center">.</p>

<style>
.center {font-size: 0px; margin-bottom: anyPercentage%;}
</style>

You may need to toy around with the percentages to get it right

The d3.js visualization examples I've been replicating on my local machine.. which import .JSON data.. all work fine on Mozilla Firefox browser; and on Chrome I get the cross-origins restrictions error. It's a weird thing how there's no issue with importing a local javascript file, but try loading a JSON and the browser gets nervous. There should at least be some setting to let the user over-ride it, the way pop-ups are blocked but I get to see an indication and a choice to unblock them.. no reason to be so Orwellian about the matter. Users shouldn't be treated as too naive to know what's best for them.

So I suggest using Firefox browser if you're working locally. And I hope people don't freak out over this and start bombing Mozilla to enforce cross-origin restrictions for local files.

For python datasets you can use an index.

tmpColumnsSQL = ("show columns in dim.date_dim")
hiveCursor.execute(tmpColumnsSQL)
columnlist = hiveCursor.fetchall()

for columns in jayscolumnlist:
    print columns[0]

for i in range(len(jayscolumnlist)):    
    print columns[i][0])

Checkout the .SaveAs() method in Excel object.

wbWorkbook.SaveAs("c:\yourdesiredFilename.csv", Microsoft.Office.Interop.Excel.XlFileFormat.xlCSV)

Or following:

public static void SaveAs()
{
    Microsoft.Office.Interop.Excel.Application app = new Microsoft.Office.Interop.Excel.ApplicationClass();
    Microsoft.Office.Interop.Excel.Workbook wbWorkbook = app.Workbooks.Add(Type.Missing);
    Microsoft.Office.Interop.Excel.Sheets wsSheet = wbWorkbook.Worksheets;
    Microsoft.Office.Interop.Excel.Worksheet CurSheet = (Microsoft.Office.Interop.Excel.Worksheet)wsSheet[1];

    Microsoft.Office.Interop.Excel.Range thisCell = (Microsoft.Office.Interop.Excel.Range)CurSheet.Cells[1, 1];

    thisCell.Value2 = "This is a test.";

    wbWorkbook.SaveAs(@"c:\one.xls", Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlShared, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
    wbWorkbook.SaveAs(@"c:\two.csv", Microsoft.Office.Interop.Excel.XlFileFormat.xlCSVWindows, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlShared, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

    wbWorkbook.Close(false, "", true);
}

Your item variable holds Array instance (in [hash_key, hash_value] format), so it doesn't expect Symbol in [] method.

This is how you could do it using Hash#each:

def format(hash)
  output = Hash.new
  hash.each do |key, value|
    output[key] = cleanup(value)
  end
  output
end

or, without this:

def format(hash)
  output = hash.dup
  output[:company_name] = cleanup(output[:company_name])
  output[:street] = cleanup(output[:street])
  output
end

You append a newline to both the username and the password, i.e. the output would be something like

Sebastian
password
John
hfsjaijn

use fwrite($fh,$user." ".$password."\n"); instead to have them both on one line.
Or use fputcsv() to write the data and fgetcsv() to fetch it. This way you would at least avoid encoding problems like e.g. with $username='Charles, III';

...i.e. setting aside all the things that are wrong about storing plain passwords in plain files and using _GET for this type of operation (use _POST instead) ;-)

@manifest in your activity:

android:windowSoftInputMode="stateAlwaysHidden|adjustPan"

Exception : java.net.ConnectException

This means your request didn't getting response from server in stipulated time. And their are some reasons for this exception:

• Too many requests overloading the server
• Request packet loss because of wrong network configuration or line overload
• Sometimes firewall consume request packet before sever getting
• Also depends on thread connection pool configuration and current status of connection pool
• Response packet lost during transition

htmlspecialchars() is perfectly adequate for filtering user input that is displayed in html forms.

The first part (setting the output size explictly) isn't too hard:

import matplotlib.pyplot as plt
list1 = [3,4,5,6,9,12]
list2 = [8,12,14,15,17,20]
fig = plt.figure(figsize=(4,3))
ax = fig.add_subplot(111)
ax.plot(list1, list2)
fig.savefig('fig1.png', dpi = 300)
fig.close()

But after a quick google search on matplotlib + tiff, I'm not convinced that matplotlib can make tiff plots. There is some mention of the GDK backend being able to do it.

One option would be to convert the output with a tool like imagemagick's convert.

(Another option is to wait around here until a real matplotlib expert shows up and proves me wrong ;-)

var objects={...}; this.getAllvalues = function () {
        var vls = [];
        for (var key in objects) {
            vls.push(objects[key]);
        }
        return vls;
    }

Another option is to ask IDEA to behave like eclipse with eclipse shortcut keys. You can use all eclipse shortcuts by enabling this.

Here are the steps:

1- With IDEA open, press Control + `. Following options will be popped up.

2- Select Keymap. You will see another pop-up. Select Eclipse there.

3- Now press Ctrl + Shift + O. You are done!

In case of Hybrid apps developed using cordova and angularjs, you can:

1) Rename the .apk file to .zip
2) Extract/Unzip the contents
3) In the assets folder you will get the www folder

You can also use the RestSharp library for example

var userName = "myuser";
var password = "mypassword";
var host = "170.170.170.170:333";
var client = new RestClient("https://" + host + "/method1");            
client.Authenticator = new HttpBasicAuthenticator(userName, password);            
var request = new RestRequest(Method.POST); 
request.AddHeader("Accept", "application/json");
request.AddHeader("Cache-Control", "no-cache");
request.AddHeader("Content-Type", "application/json");            
request.AddParameter("application/json","{}",ParameterType.RequestBody);
IRestResponse response = client.Execute(request);

• Very Simple

  private void button1_Click(object sender, EventArgs e)
  {
      ListViewItem item = new ListViewItem();
      item.SubItems.Add(textBox2.Text);
      item.SubItems.Add(textBox3.Text);
      item.SubItems.Add(textBox4.Text);
      listView1.Items.Add(item);
      textBox2.Clear();
      textBox3.Clear();
      textBox4.Clear();
  }
  

• You can also Do this stuff...

      ListViewItem item = new ListViewItem();
      item.SubItems.Add("Santosh");
      item.SubItems.Add("26");
      item.SubItems.Add("India");
  

From the documentation of XPath ( http://www.w3.org/TR/xpath/#location-paths ):

child::* selects all element children of the context node

child::text() selects all text node children of the context node

child::node() selects all the children of the context node, whatever their node type

So I guess your answer is:

$doc/PRESENTEDIN/X/child::node()

And if you want a flatten array of all nested nodes:

$doc/PRESENTEDIN/X/descendant::node()

.bashrc is not meant to be executed but sourced. Try this instead:

. ~/.bashrc

Class selectors are prefixed with a dot. Your .find() is missing that so jQuery thinks you're looking for <myClass> elements.

var myVar = $("#start").find('.myClass').val();

Horizontal scaling means that you scale by adding more machines into your pool of resources whereas Vertical scaling means that you scale by adding more power (CPU, RAM) to an existing machine.

An easy way to remember this is to think of a machine on a server rack, we add more machines across the horizontal direction and add more resources to a machine in the vertical direction.

In the database world, horizontal-scaling is often based on the partitioning of the data i.e. each node contains only part of the data, in vertical-scaling the data resides on a single node and scaling is done through multi-core i.e. spreading the load between the CPU and RAM resources of that machine.

With horizontal-scaling it is often easier to scale dynamically by adding more machines into the existing pool - Vertical-scaling is often limited to the capacity of a single machine, scaling beyond that capacity often involves downtime and comes with an upper limit.

Good examples of horizontal scaling are Cassandra, MongoDB, Google Cloud Spanner .. and a good example of vertical scaling is MySQL - Amazon RDS (The cloud version of MySQL). It provides an easy way to scale vertically by switching from small to bigger machines. This process often involves downtime.

In-Memory Data Grids such as GigaSpaces XAP, Coherence etc.. are often optimized for both horizontal and vertical scaling simply because they're not bound to disk. Horizontal-scaling through partitioning and vertical-scaling through multi-core support.

You can read more on this subject in my earlier posts: Scale-out vs Scale-up and The Common Principles Behind the NOSQL Alternatives

To not have to worry whether you are running your scripts on Windows, Mac or Linux install the cross-env package. Then you can use your scripts easily, like so:

"scripts": {
    "start-dev": "cross-env NODE_ENV=development nodemon --exec babel-node -- src/index.js",
    "start-prod": "cross-env NODE_ENV=production nodemon --exec babel-node -- src/index.js"
}

Massive props to the developers of this package.

npm install --save-dev cross-env

If it's always going to be an even LHS/RHS split, you can also use the partition method that's built into strings. It returns a 3-tuple as (LHS, separator, RHS) if the separator is found, and (original_string, '', '') if the separator wasn't present:

>>> "2.7.0_bf4fda703454".partition('_')
('2.7.0', '_', 'bf4fda703454')

>>> "shazam".partition("_")
('shazam', '', '')

if you're working with some kind of subversion: delete the project and re-download it, it worked for me :S

You can use this command to quit an app in iOS Simulator

xcrun simctl terminate booted com.apple.mobilesafari

You will need to know the bundle id of the app you have installed in the simulator. You can refer to this link

You need to use multiple rules to implement OR-like semantics, since matches are always AND-ed together within a rule. Alternatively, you can do matching against port-indexing ipsets (ipset create blah bitmap:port).

The below solution is the simplest one:

Console.WriteLine("[{0}]", string.Join(", ", array));

Output: [1, 2, 3, 4, 5]

Another short solution:

Array.ForEach(array,  val => Console.Write("{0} ", val));

Output: 1 2 3 4 5. Or if you need to add add ,, use the below:

int i = 0;
Array.ForEach(array,  val => Console.Write(i == array.Length -1) ? "{0}" : "{0}, ", val));

Output: 1, 2, 3, 4, 5

If you like to give a special kind of experience to the users you could use pushState to bring a wide range of characters to the browser's url:

var u="";var tt=168;
for(var i=0; i< 250;i++){
 var x = i+250*tt;
console.log(x);
 var c = String.fromCharCode(x);
 u+=c; 
}
history.pushState({},"",250*tt+u);

I know this question has been answered. But my requirement was slightly different. Instead of value I wanted to filter by text. So i modified the answer by @William Herry like this.

var array = ['Administration', 'Finance', 'HR', 'IT', 'Marketing', 'Materials', 'Reception', 'Support'];
if (somecondition) {
   $(array).each(function () {
       $("div#deprtmnts option:contains(" + this + ")").unwrap();
   });
}
else{
   $(array).each(function () {
       $("div#deprtmnts option:contains(" + this + ")").wrap('<span/>');
   });
}

This way you can use value also by replacing contains like this

 $("div#ovrcateg option[value=" + this + "]").wrap('<span/>');

I found a flow which is fastest for me, by first associating a keyboard shortcut Alt+k to "Compare Active File With..." (#a). (Similar to wisbucky's answer but further improved and more step-wise.)

Then, to compare two files:

1. Open or focus file B (will be editable in compare view by default). E.g. by drag-drop from File Explorer to VS Code's center.
2. Open or focus file A.
3. Press Alt+k, a quick open menu will be shown with file B focused.
4. Press Enter.

Result: file A on left and file B on right. (Tested on VS Code 1.27.1)

Remarks

#a - to do so, press Ctrl-k Ctrl-s to show Keyboard Shortcuts, type compare on the top search box, and double click the "Keybinding" column for "Compare Active File With...", press Alt+k then Enter to assign it.

Use:

git reset HEAD filepath

For example:

git reset HEAD om211/src/META-INF/persistence.xml

+ theme(plot.title = element_text(size=22))

Here is the full set of things you can change in element_text:

element_text(family = NULL, face = NULL, colour = NULL, size = NULL,
  hjust = NULL, vjust = NULL, angle = NULL, lineheight = NULL,
  color = NULL)

Maybe it help you. I use this in my app

As @Raf Z commented on this question, dplyr now has mutate_if. Super useful, simple and readable.

Maven is cool.

Stop listening to the alternatives, because right now, there aren't any - which aren't just toys.

Apart from the Microsoft development toolchain - it's best technology that money can't buy.

All these groups who are trying to push 'toolchain du jour' - it's just a cheap attempt to sow confusion and grab market-share.

Haters be hating.

• SBT

Greatest misnomer in history of the earth. Can your Build pass a Turing test? Fucking ridiculous, a step 10 years back in time with it's ridiculous DSL. Uses IVY dependency management, Maven's middle sibling.

• ANT

Great for that first project after you graduate from Shockwave development.

You understand XML, and are enthusiastic, but don't really understand build phases, restarting a project 6 months later, why Version Controlling binary artifacts is a false panacea or that someone other than oneself will one day try to work with your project.

• MAKE

If the whole world runs in the same UNIX terminal, and speaks fluent Bash, then yeah. But why not just become a C/C++ programmer, it's much more fun than Java anyhow.

• Ruby (Various)

Whatever. Niche, slow. Just develop Ruby then, stay away from Java development.

• Python

People use Java where they don't trust Python (anywhere there's money involved). If your system is running Python anyway, you wont even be reading this, unless of course you want the Java money - but are stuck developing Python in some web shop.

• Clojure (Various)

In honour of Stallman, I'll learn Lisp - but for Emacs, not so that I run it upon my VM. I feel that it cheapens the experience.

There is one more difference of using the app and listening to http server is when you want to setup for https server

To setup for https, you need the code below:

var https = require('https');
var server = https.createServer(app).listen(config.port, function() {
    console.log('Https App started');
});

The app from express will return http server only, you cannot set it in express, so you will need to use the https server command

var express = require('express');
var app = express();
app.listen(1234);

You can reset the index using reset_index to get back a default index of 0, 1, 2, ..., n-1 (and use drop=True to indicate you want to drop the existing index instead of adding it as an additional column to your dataframe):

In [19]: df2 = df2.reset_index(drop=True)

In [20]: df2
Out[20]:
   x  y
0  0  0
1  0  1
2  0  2
3  1  0
4  1  1
5  1  2
6  2  0
7  2  1
8  2  2

Using attr() pointing to an external domain may trigger an error like this in Chrome: "Refused to display document because display forbidden by X-Frame-Options". The workaround to this can be to move the whole iframe HTML code into the script (eg. using .html() in jQuery).

Example:

var divMapLoaded = false;
$("#container").scroll(function() {
    if ((!divMapLoaded) && ($("#map").position().left <= $("#map").width())) {
    $("#map-iframe").html("<iframe id=\"map-iframe\" " +
        "width=\"100%\" height=\"100%\" frameborder=\"0\" scrolling=\"no\" " +
        "marginheight=\"0\" marginwidth=\"0\" " +
        "src=\"http://www.google.it/maps?t=m&amp;cid=0x3e589d98063177ab&amp;ie=UTF8&amp;iwloc=A&amp;brcurrent=5,0,1&amp;ll=41.123115,16.853177&amp;spn=0.005617,0.009943&amp;output=embed\"" +
        "></iframe>");
    divMapLoaded = true;
}

You should use the options 'year', 'month', and 'date' when initializing to specify the initial date value used by fullcalendar:

$('#calendar').fullCalendar({
 year: 2012,
 month: 4,
 date: 25
});  // This will initialize for May 25th, 2012.

See the function setYMD(date,y,m,d) in the fullcalendar.js file; note that the JavaScript setMonth, setDate, and setFullYear functions are used, so your month value needs to be 0-based (Jan is 0).

UPDATE: As others have noted in the comments, the correct way now (V3 as of writing this edit) is to initialize the defaultDate property to a value that is

anything the Moment constructor accepts, including an ISO8601 date string like "2014-02-01"

as it uses Moment.js. Documentation here.

Updated example:

$('#calendar').fullCalendar({
    defaultDate: "2012-05-25"
});  // This will initialize for May 25th, 2012.

Starting Mongo 4.4, we can achieve this join within an aggregation pipeline by coupling the new $unionWith aggregation stage with $group's new $accumulator operator:

// > db.users.find()
//   [{ user: 1, name: "x" }, { user: 2, name: "y" }]
// > db.books.find()
//   [{ user: 1, book: "a" }, { user: 1, book: "b" }, { user: 2, book: "c" }]
// > db.movies.find()
//   [{ user: 1, movie: "g" }, { user: 2, movie: "h" }, { user: 2, movie: "i" }]
db.users.aggregate([
  { $unionWith: "books"  },
  { $unionWith: "movies" },
  { $group: {
    _id: "$user",
    user: {
      $accumulator: {
        accumulateArgs: ["$name", "$book", "$movie"],
        init: function() { return { books: [], movies: [] } },
        accumulate: function(user, name, book, movie) {
          if (name) user.name = name;
          if (book) user.books.push(book);
          if (movie) user.movies.push(movie);
          return user;
        },
        merge: function(userV1, userV2) {
          if (userV2.name) userV1.name = userV2.name;
          userV1.books.concat(userV2.books);
          userV1.movies.concat(userV2.movies);
          return userV1;
        },
        lang: "js"
      }
    }
  }}
])
// { _id: 1, user: { books: ["a", "b"], movies: ["g"], name: "x" } }
// { _id: 2, user: { books: ["c"], movies: ["h", "i"], name: "y" } }

• $unionWith combines records from the given collection within documents already in the aggregation pipeline. After the 2 union stages, we thus have all users, books and movies records within the pipeline.

• We then $group records by $user and accumulate items using the $accumulator operator allowing custom accumulations of documents as they get grouped:

  • the fields we're interested in accumulating are defined with accumulateArgs.
  • init defines the state that will be accumulated as we group elements.
  • the accumulate function allows performing a custom action with a record being grouped in order to build the accumulated state. For instance, if the item being grouped has the book field defined, then we update the books part of the state.
  • merge is used to merge two internal states. It's only used for aggregations running on sharded clusters or when the operation exceeds memory limits.

While sizeof works for this specific type of string:

char str[] = "content";
int charcount = sizeof str - 1; // -1 to exclude terminating '\0'

It does not work if str is pointer (sizeof returns size of pointer, usually 4 or 8) or array with specified length (sizeof will return the byte count matching specified length, which for char type are same).

Just use strlen().

From your description I suspect the most likely explanation is that you have some error in your memory management. You said you've been working on iPhone development for a few weeks, but not whether you are experienced with Objective C in general. If you've come from another background it can take a little while before you really internalise the memory management rules - unless you make a big point of it.

Remember, anything you get from an allocation function (usually the static alloc method, but there are a few others), or a copy method, you own the memory too and must release it when you are done.

But if you get something back from just about anything else including factory methods (e.g. [NSString stringWithFormat]) then you'll have an autorelease reference, which means it could be released at some time in the future by other code - so it is vital that if you need to keep it around beyond the immediate function that you retain it. If you don't, the memory may remain allocated while you are using it, or be released but coincidentally still valid, during your emulator testing, but is more likely to be released and show up as bad access errors when running on the device.

The best way to track these things down, and a good idea anyway (even if there are no apparent problems) is to run the app in the Instruments tool, especially with the Leaks option.

You can do this entirely with html and css and i have.

HTML First you give the div you wish to hide an ID to target like #view_element and a class to target like #hide_element. You can if you wish make both of these classes but i don't know if you can make them both IDs. Then have your Show button target your show id and your Hide button target your hide class. That is it for the html the hiding and showing is done in the CSS.

CSS The css to show and hide this should look something like this

#hide_element:target {
    display:none;
}

.show_element:target{
    display:block;
}

This should allow you to hide and show elements at will. This should work nicely on spans and divs.

While using the wait and notify or notifyAll methods in Java the following things must be remembered:

1. Use notifyAll instead of notify if you expect that more than one thread will be waiting for a lock.
2. The wait and notify methods must be called in a synchronized context. See the link for a more detailed explanation.
3. Always call the wait() method in a loop because if multiple threads are waiting for a lock and one of them got the lock and reset the condition, then the other threads need to check the condition after they wake up to see whether they need to wait again or can start processing.
4. Use the same object for calling wait() and notify() method; every object has its own lock so calling wait() on object A and notify() on object B will not make any sense.

Compass adjusts the way partials are imported. It allows importing components based solely on their name, without specifying the path.

Before you can do @import 'compass';, you should:

Install Compass as a Ruby gem:

gem install compass

After that, you should use Compass's own command line tool to compile your SASS code:

cd path/to/your/project/
compass compile

Note that Compass reqiures a configuration file called config.rb. You should create it for Compass to work.

The minimal config.rb can be as simple as this:

css_dir =   "css"
sass_dir =  "sass"

And your SASS code should reside in sass/.

Instead of creating a configuration file manually, you can create an empty Compass project with compass create <project-name> and then copy your SASS code inside it.

Note that if you want to use Compass extensions, you will have to:

1. require them from the config.rb;
2. import them from your SASS file.

More info here: http://compass-style.org/help/

A static variable declared in a header file outside of the class would be file-scoped in every .c file which includes the header. That means separate copy of a variable with same name is accessible in each of the .c files where you include the header file.

A static class variable on the other hand is class-scoped and the same static variable is available to every compilation unit that includes the header containing the class with static variable.

If the application is already open (even in background), it will be restored by "start" command. Exit the program if running then /max or /min will work

The accepted answer to how to replace multiple strings together in Oracle suggests using nested REPLACE statements, and I don't think there is a better way.

If you are going to make heavy use of this, you could consider writing your own function:

CREATE TYPE t_text IS TABLE OF VARCHAR2(256);

CREATE FUNCTION multiple_replace(
  in_text IN VARCHAR2, in_old IN t_text, in_new IN t_text
)
  RETURN VARCHAR2
AS
  v_result VARCHAR2(32767);
BEGIN
  IF( in_old.COUNT <> in_new.COUNT ) THEN
    RETURN in_text;
  END IF;
  v_result := in_text;
  FOR i IN 1 .. in_old.COUNT LOOP
    v_result := REPLACE( v_result, in_old(i), in_new(i) );
  END LOOP;
  RETURN v_result;
END;

and then use it like this:

SELECT multiple_replace( 'This is #VAL1# with some #VAL2# to #VAL3#',
                         NEW t_text( '#VAL1#', '#VAL2#', '#VAL3#' ),
                         NEW t_text( 'text', 'tokens', 'replace' )
                       )
FROM dual

This is text with some tokens to replace

If all of your tokens have the same format ('#VAL' || i || '#'), you could omit parameter in_old and use your loop-counter instead.

You can also post multiple inputs with the same name and have them save into an array by adding empty square brackets to the input name like this:

<input type="text" name="comment[]" value="comment1"/>
<input type="text" name="comment[]" value="comment2"/>
<input type="text" name="comment[]" value="comment3"/>
<input type="text" name="comment[]" value="comment4"/>

If you use php:

print_r($_POST['comment']) 

you will get this:

Array ( [0] => 'comment1' [1] => 'comment2' [2] => 'comment3' [3] => 'comment4' )

My solution (vb.net):

Private Function ConvertToBoolean(p1 As Object) As Boolean
    If p1 Is Nothing Then Return False
    If IsDBNull(p1) Then Return False
    If p1.ToString = "1" Then Return True
    If p1.ToString.ToLower = "true" Then Return True
    Return False
End Function

Both styles, with a touch of tweaking, would work.

The first method uses a Javascript Constructor, which like most things has pros and cons.

 // By convention, constructors start with an upper case letter
function MakePerson(name,age) {
  // The magic variable 'this' is set by the Javascript engine and points to a newly created object that is ours.
  this.name = name;
  this.age = age;
  this.occupation = "Hobo";
}
var jeremy = new MakePerson("Jeremy", 800);

On the other hand, your other method is called the 'Revealing Closure Pattern' if I recall correctly.

function makePerson(name2, age2) {
  var name = name2;
  var age = age2;

  return {
    name: name,
    age: age
  };
}

Following are the ways

1. From the code (the way you have mentioned) ->

   displayBox.Text += sent + "\r\n";
   

   or

   displayBox.Text += sent + Environment.NewLine;
   

2. From the UI
   a) WPF

   Set TextWrapping="Wrap" and AcceptsReturn="True"   
   

   Press Enter key to the textbox and new line will be created

   b) Winform text box

   Set TextBox.MultiLine and TextBox.AcceptsReturn to true
   

You can use following code for open actionSheet in Swift

        let alert = UIAlertController(title: enter your title, message: "Enter your messgage. ", preferredStyle: UIAlertControllerStyle.Alert)

        alert.addTextFieldWithConfigurationHandler(configurationTextField)

        alert.addAction(UIAlertAction(title: "Close", style: UIAlertActionStyle.Cancel, handler:{ (UIAlertAction)in
            print("User click Cancel button")
        }))

        alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler:{ (UIAlertAction)in
            print("User click Ok button")


        }))
        self.presentViewController(alert, animated: true, completion: {
            print("completion block")
        })

What you want is the outer HTML, not the inner HTML :

$('<some element/>')[0].outerHTML;

I just found my own solution to this problem, or at least my problem.
I was using justify-content: space-around instead of justify-content: space-between;.

This way the end elements will stick to the top and bottom, and you could have custom margins if you wanted.

Try this,

IFS=''
while read line
do
    echo $line
done < file.txt

EDIT:

From man bash

IFS - The Internal Field Separator that is used for word
splitting after expansion and to split lines into words
with  the  read  builtin  command. The default value is
``<space><tab><newline>''

I considered giving a comment under the answer by taggon to this very question, but well, i felt it owed more explanation for those interested in details.

Uncaught TypeError: Cannot read property 'value' of undefined is strictly a JavaScript error.
(Note that value can be anything, but for this question value is 'map')

It's critical to understand that point, just so you avoid endless debugging cycles.
This error is common especially if just starting out in JavaScript (and it's libraries/frameworks).
For React, this has a lot to do with understanding the component lifecycle methods.

// Follow this example to get the context
// Ignore any complexity, focus on how 'props' are passed down to children

import React, { useEffect } from 'react'

// Main component
const ShowList = () => {
  // Similar to componentDidMount and componentDidUpdate
  useEffect(() => {// dispatch call to fetch items, populate the redux-store})

  return <div><MyItems items={movies} /></div>
}

// other component
const MyItems = props =>
  <ul>
    {props.items.map((item, i) => <li key={i}>item</li>)}
  </ul>


/**
  The above code should work fine, except for one problem.
  When compiling <ShowList/>,
  React-DOM renders <MyItems> before useEffect (or componentDid...) is called.
  And since `items={movies}`, 'props.items' is 'undefined' at that point.
  Thus the error message 'Cannot read property map of undefined'
 */

As a way to tackle this problem, @taggon gave a solution (see first anwser or link).

Solution: Set an initial/default value.
In our example, we can avoid items being 'undefined' by declaring a default value of an empty array.

Why? This allows React-DOM to render an empty list initially.
And when the useEffect or componentDid... method is executed, the component is re-rendered with a populated list of items.

// Let's update our 'other' component
// destructure the `items` and initialize it as an array

const MyItems = ({items = []}) =>
  <ul>
    {items.map((item, i) => <li key={i}>item</li>)}
  </ul>

I can't say enough good things about Nick Sieger's multipart-post library.

It adds support for multipart posting directly to Net::HTTP, removing your need to manually worry about boundaries or big libraries that may have different goals than your own.

Here is a little example on how to use it from the README:

require 'net/http/post/multipart'

url = URI.parse('http://www.example.com/upload')
File.open("./image.jpg") do |jpg|
  req = Net::HTTP::Post::Multipart.new url.path,
    "file" => UploadIO.new(jpg, "image/jpeg", "image.jpg")
  res = Net::HTTP.start(url.host, url.port) do |http|
    http.request(req)
  end
end

You can check out the library here: http://github.com/nicksieger/multipart-post

or install it with:

$ sudo gem install multipart-post

If you're connecting via SSL you need to start the connection like this:

n = Net::HTTP.new(url.host, url.port) 
n.use_ssl = true
# for debugging dev server
#n.verify_mode = OpenSSL::SSL::VERIFY_NONE
res = n.start do |http|

I don't use Consolas, though it does look good on LCD, but sometimes I'm not on LCD, like when I'm giving presentations and then it looks crap.

My current font of choice for programming is the Liberation Mono font.

Oh man, just discovered why the text on Stack Overflow looks like crap, it forces Consolas which is a cleartype font, and on my current setup which didn't have cleartype enabled, it looks very bad.

Going to make a bugreport on uservoice.

If you are going to display this tree on the GUI, you can use TreeView and TreeNode. (I suppose technically you can create a TreeNode without putting it on a GUI, but it does have more overhead than a simple homegrown TreeNode implementation.)

I did notice something of interest here: In my 2.3.4 phone I can't see AP/AdHoc SSIDs in the Settings > Wireless & Networks menu. On an Acer A500 running 4.0.3 I do see them, prefixed by (*)

However in the following bit of code that I adapted from (can't remember source, sorry!) I do see the Ad Hoc show up in the Wifi Scan on my 2.3.4 phone. I am still looking to actually connect and create a socket + input/outputStream. But, here ya go:

    public class MainActivity extends Activity {

private static final String CHIPKIT_BSSID = "E2:14:9F:18:40:1C";
private static final int CHIPKIT_WIFI_PRIORITY = 1;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    final Button btnDoSomething = (Button) findViewById(R.id.btnDoSomething);
    final Button btnNewScan = (Button) findViewById(R.id.btnNewScan);
    final TextView textWifiManager = (TextView) findViewById(R.id.WifiManager);
    final TextView textWifiInfo = (TextView) findViewById(R.id.WifiInfo);
    final TextView textIp = (TextView) findViewById(R.id.Ip);

    final WifiManager myWifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
    final WifiInfo myWifiInfo = myWifiManager.getConnectionInfo();

    WifiConfiguration wifiConfiguration = new WifiConfiguration();
    wifiConfiguration.BSSID = CHIPKIT_BSSID;
    wifiConfiguration.priority = CHIPKIT_WIFI_PRIORITY;
    wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
    wifiConfiguration.allowedKeyManagement.set(KeyMgmt.NONE);
    wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
    wifiConfiguration.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
    wifiConfiguration.status = WifiConfiguration.Status.ENABLED;

    myWifiManager.setWifiEnabled(true);

    int netID = myWifiManager.addNetwork(wifiConfiguration);

    myWifiManager.enableNetwork(netID, true);

    textWifiInfo.setText("SSID: " + myWifiInfo.getSSID() + '\n' 
            + myWifiManager.getWifiState() + "\n\n");

    btnDoSomething.setOnClickListener(new View.OnClickListener() {          
        public void onClick(View v) {
            clearTextViews(textWifiManager, textIp);                
        }           
    });

    btnNewScan.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            getNewScan(myWifiManager, textWifiManager, textIp);
        }
    });     
}

private void clearTextViews(TextView...tv) {
    for(int i = 0; i<tv.length; i++){
        tv[i].setText("");
    }       
}

public void getNewScan(WifiManager wm, TextView...textViews) {
    wm.startScan();

    List<ScanResult> scanResult = wm.getScanResults();

    String scan = "";

    for (int i = 0; i < scanResult.size(); i++) {
        scan += (scanResult.get(i).toString() + "\n\n");
    }

    textViews[0].setText(scan);
    textViews[1].setText(wm.toString());
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

Don't forget that in Eclipse you can use Ctrl+Shift+[letter O] to fill in the missing imports...

and my manifest:

    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.digilent.simpleclient"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

Hope that helps!

Instead of having two arrays of Strings, have one array of a custom class which contains your two strings.

What you are talking about is called dot sourcing. And it's evil. But no worries, there is a better and easier way to do what you are wanting with modules (it sounds way scarier than it is). The major benefit of using modules is that you can unload them from the shell if you need to, and it keeps the variables in the functions from creeping into the shell (once you dot source a function file, try calling one of the variables from a function in the shell, and you'll see what I mean).

So first, rename the .ps1 file that has all your functions in it to MyFunctions.psm1 (you've just created a module!). Now for a module to load properly, you have to do some specific things with the file. First for Import-Module to see the module (you use this cmdlet to load the module into the shell), it has to be in a specific location. The default path to the modules folder is $home\Documents\WindowsPowerShell\Modules.

In that folder, create a folder named MyFunctions, and place the MyFunctions.psm1 file into it (the module file must reside in a folder with exactly the same name as the PSM1 file).

Once that is done, open PowerShell, and run this command:

Get-Module -listavailable

If you see one called MyFunctions, you did it right, and your module is ready to be loaded (this is just to ensure that this is set up right, you only have to do this once).

To use the module, type the following in the shell (or put this line in your $profile, or put this as the first line in a script):

Import-Module MyFunctions

You can now run your functions. The cool thing about this is that once you have 10-15 functions in there, you're going to forget the name of a couple. If you have them in a module, you can run the following command to get a list of all the functions in your module:

Get-Command -module MyFunctions

It's pretty sweet, and the tiny bit of effort that it takes to set up on the front side is WAY worth it.

If you don't care about the order you can just shove the items into a HashSet, if you do want to maintain the order you can do something like this:

var unique = new List<T>();
var hs = new HashSet<T>();
foreach (T t in list)
    if (hs.Add(t))
        unique.Add(t);

Or the Linq way:

var hs = new HashSet<T>();
list.All( x =>  hs.Add(x) );

Edit: The HashSet method is O(N) time and O(N) space while sorting and then making unique (as suggested by @lassevk and others) is O(N*lgN) time and O(1) space so it's not so clear to me (as it was at first glance) that the sorting way is inferior (my apologies for the temporary down vote...)

For pre PHP 5:

function iso8601($time=false) {
    if(!$time) $time=time();
    return date("Y-m-d", $time) . 'T' . date("H:i:s", $time) .'+00:00';
}

I couldn't get the SSIS import / export to work as I got the error 'Failure inserting into the read-only column "id"'. Nor could I get http://sqlazuremw.codeplex.com/ to work, and the links above to SQL Azure Data Sync didn't work for me.

But I found an excellent blog post about BACPAC files: http://dacguy.wordpress.com/2012/01/24/sql-azure-importexport-service-has-hit-production/

In the video in the post the blog post's author runs through six steps:

1. Make or go to a storage account in the Azure Management Portal. You'll need the Blob URL and the Primary access key of the storage account.

2. The blog post advises making a new container for the bacpac file and suggests using the Azure Storage Explorer for that. (N.B. you'll need the Blob URL and the Primary access key of the storage account to add it to the Azure Storage Explorer.)

3. In the Azure Management Portal select the database you want to export and click 'Export' in the Import and Export section of the ribbon.

4. The resulting dialogue requires your username and password for the database, the blob URL, and the access key. Don't forget to include the container in the blob URL and to include a filename (e.g. https://testazurestorage.blob.core.windows.net/dbbackups/mytable.bacpac).

5. After you click Finish the database will be exported to the BACPAC file. This can take a while. You may see a zero byte file show up immediately if you check in the Azure Storage Explorer. This is the Import / Export Service checking that it has write access to the blob-store.

6. Once that is done you can use the Azure Storage Explorer to download the BACPAC file and then in the SQL Server Management Studio right-click your local server's database folder and choose Import Data Tier Application that will start the wizard which reads in the BACPAC file to produce the copy of your Azure database. The wizard can also connect directly to the blob-store to obtain the BACPAC file if you would rather not copy it locally first.

The last step may only be available in the SQL Server 2012 edition of the SQL Server Management Studio (that's the version I am running). I do not have earlier ones on this machine to check. In the blog post the author uses the command line tool DacImportExportCli.exe for the import which I believe is available at http://sqldacexamples.codeplex.com/releases

In percentage :

$('.your-class').click(function (e){
    var $this = $(this); // or use $(e.target) in some cases;
    var offset = $this.offset();
    var width = $this.width();
    var height = $this.height();
    var posX = offset.left;
    var posY = offset.top;
    var x = e.pageX-posX;
        x = parseInt(x/width*100,10);
        x = x<0?0:x;
        x = x>100?100:x;
    var y = e.pageY-posY;
        y = parseInt(y/height*100,10);
        y = y<0?0:y;
        y = y>100?100:y;
    console.log(x+'% '+y+'%');
});

In Visual Studio 2013 AND VS15 (but i guess if the same for all other version) just press F4 and change this two properties: -Anonymous Authentication: Disable -Windows Authentication: Enable

It is my solution for that:

onDelete(id: number) {
    this.service.delete(id).then(() => {
        let index = this.documents.findIndex(d => d.id === id); //find index in your array
        this.documents.splice(index, 1);//remove element from array
    });

    event.stopPropagation();
}

Suppose you have a function that returns a substantial object:

Matrix multiply(const Matrix &a, const Matrix &b);

When you write code like this:

Matrix r = multiply(a, b);

then an ordinary C++ compiler will create a temporary object for the result of multiply(), call the copy constructor to initialise r, and then destruct the temporary return value. Move semantics in C++0x allow the "move constructor" to be called to initialise r by copying its contents, and then discard the temporary value without having to destruct it.

This is especially important if (like perhaps the Matrix example above), the object being copied allocates extra memory on the heap to store its internal representation. A copy constructor would have to either make a full copy of the internal representation, or use reference counting and copy-on-write semantics interally. A move constructor would leave the heap memory alone and just copy the pointer inside the Matrix object.

You can quote the entire path as in windows or you can escape the spaces like in:

/foo\ folder\ with\ space/foo.sh -help

Both ways will work!

I don't understand why some people are suggesting using cross apply or outer apply to convert the xml into a table of values. For me, that just brought back way too much data.

Here's my example of how you'd create an xml object, then turn it into a table.

(I've added spaces in my xml string, just to make it easier to read.)

DECLARE @str nvarchar(2000)

SET @str = ''
SET @str = @str + '<users>'
SET @str = @str + '  <user>'
SET @str = @str + '     <firstName>Mike</firstName>'
SET @str = @str + '     <lastName>Gledhill</lastName>'
SET @str = @str + '     <age>31</age>'
SET @str = @str + '  </user>'
SET @str = @str + '  <user>'
SET @str = @str + '     <firstName>Mark</firstName>'
SET @str = @str + '     <lastName>Stevens</lastName>'
SET @str = @str + '     <age>42</age>'
SET @str = @str + '  </user>'
SET @str = @str + '  <user>'
SET @str = @str + '     <firstName>Sarah</firstName>'
SET @str = @str + '     <lastName>Brown</lastName>'
SET @str = @str + '     <age>23</age>'
SET @str = @str + '  </user>'
SET @str = @str + '</users>'

DECLARE @xml xml
SELECT @xml = CAST(CAST(@str AS VARBINARY(MAX)) AS XML) 

--  Iterate through each of the "users\user" records in our XML
SELECT 
    x.Rec.query('./firstName').value('.', 'nvarchar(2000)') AS 'FirstName',
    x.Rec.query('./lastName').value('.', 'nvarchar(2000)') AS 'LastName',
    x.Rec.query('./age').value('.', 'int') AS 'Age'
FROM @xml.nodes('/users/user') as x(Rec)

And here's the output:

Fix your issue with this

tbody {
  display: table-caption;
  height: 200px;
  caption-side: bottom;
  overflow: auto;
}

If this is for Python 2.x or for Python 3.2+, you can also use callable(). It used to be deprecated, but is now undeprecated, so you can use it again. You can read the discussion here: http://bugs.python.org/issue10518. You can do this with:

callable(obj)

If this is for Python 3.x but before 3.2, check if the object has a __call__ attribute. You can do this with:

hasattr(obj, '__call__')

The oft-suggested types.FunctionTypes approach is not correct because it fails to cover many cases that you would presumably want it to pass, like with builtins:

>>> isinstance(open, types.FunctionType)
False

>>> callable(open)
True

The proper way to check properties of duck-typed objects is to ask them if they quack, not to see if they fit in a duck-sized container. Don't use types.FunctionType unless you have a very specific idea of what a function is.

If you are looking for a hard limit across all uploads on the site, you can limit these in php.ini by setting the following:

`upload_max_filesize = 2M` `post_max_size = 2M`

that will set the maximum upload limit to 2 MB

Actually with Java 8 the right way is to use:

System.getProperty("user.home");

The bug JDK-6519127 has been fixed and the "Incompatibilities between JDK 8 and JDK 7" section of the release notes states:

Area: Core Libs / java.lang

Synopsis

The steps used to determine the user's home directory on Windows have changed to follow the Microsoft recommended approach. This change might be observable on older editions of Windows or where registry settings or environment variables are set to other directories. Nature of Incompatibility

Despite the question being old I leave this for future reference.

SELECT some_cols

In addition to what @berguiga-mohamed-amine stated, I just found that a wildcard requires leaving the module argument the empty string:

compile ("com.github.jsonld-java:jsonld-java:$jsonldJavaVersion") {
    exclude group: 'org.apache.httpcomponents', module: ''
    exclude group: 'org.slf4j', module: ''
}

Align the text area box to the label, not the label to the text area,

label {
    width: 180px;
    display: inline-block;
}

textarea{
    vertical-align: middle;
}

<label for="myfield">Label text</label><textarea id="myfield" rows="5" cols="30"></textarea>

This fix my problem.

Be careful while adding a property to the existing object using .(dot) method.

(.dot) method of adding a property to the object should only be used if you know the 'key' beforehand otherwise use the [bracket] method.

Example:

   var data = {_x000D_
        'Property1': 1_x000D_
    };_x000D_
    _x000D_
    // Two methods of adding a new property [ key (Property4), value (4) ] to the_x000D_
    // existing object (data)_x000D_
    data['Property2'] = 2; // bracket method_x000D_
    data.Property3 = 3;    // dot method_x000D_
    console.log(data);     // { Property1: 1, Property2: 2, Property3: 3 }_x000D_
    _x000D_
    // But if 'key' of a property is unknown and will be found / calculated_x000D_
    // dynamically then use only [bracket] method not a dot method    _x000D_
    var key;_x000D_
    for(var i = 4; i < 6; ++i) {_x000D_
     key = 'Property' + i;     // Key - dynamically calculated_x000D_
     data[key] = i; // CORRECT !!!!_x000D_
    }_x000D_
    console.log(data); _x000D_
    // { Property1: 1, Property2: 2, Property3: 3, Property4: 4, Property5: 5 }_x000D_
    _x000D_
    for(var i = 6; i < 2000; ++i) {_x000D_
     key = 'Property' + i; // Key - dynamically calculated_x000D_
     data.key = i;         // WRONG !!!!!_x000D_
    }_x000D_
    console.log(data); _x000D_
    // { Property1: 1, Property2: 2, Property3: 3, _x000D_
    //   Property4: 4, Property5: 5, key: 1999 }

Note the problem in the end of console log - 'key: 1999' instead of Property6: 6, Property7: 7,.........,Property1999: 1999. So the best way of adding dynamically created property is the [bracket] method.

It appears there's a simple answer. Consider this:

var Child = React.createClass({
  render: function() {
    <a onClick={this.props.onClick.bind(null, this)}>Click me</a>
  }
});

var Parent = React.createClass({
  onClick: function(component, event) {
    component.props // #=> {Object...}
  },
  render: function() {
    <Child onClick={this.onClick} />
  }
});

The key is calling bind(null, this) on the this.props.onClick event, passed from the parent. Now, the onClick function accepts arguments component, AND event. I think that's the best of all worlds.

UPDATE: 9/1/2015

This was a bad idea: letting child implementation details leak in to the parent was never a good path. See Sebastien Lorber's answer.

The bottom statement is equivalent to:

.half {
   flex-grow: 0;
   flex-shrink: 0;
   flex-basis: 50%;
}

Which, in this case, would be equivalent as the box is not allowed to flex and therefore retains the initial width set by flex-basis.

Flex-basis defines the default size of an element before the remaining space is distributed so if the element were allowed to flex (grow/shrink) it may not be 50% of the width of the page.

I've found that I regularly return to https://css-tricks.com/snippets/css/a-guide-to-flexbox/ for help regarding flexbox :)

Just a note that the constant keyword use for safe-area margins has been updated to env for 11.2 beta+

With RHEL 7 / CentOS 7, firewalld was introduced to manage iptables. IMHO, firewalld is more suited for workstations than for server environments.

It is possible to go back to a more classic iptables setup. First, stop and mask the firewalld service:

systemctl stop firewalld
systemctl mask firewalld

Then, install the iptables-services package:

yum install iptables-services

Enable the service at boot-time:

systemctl enable iptables

Managing the service

systemctl [stop|start|restart] iptables

Saving your firewall rules can be done as follows:

service iptables save

or

/usr/libexec/iptables/iptables.init save

Evaluating String variables with a switch statement have been implemented in Java SE 7, and hence it only works in java 7. You can also have a look at how this new feature is implemented in JDK 7.

python2 and python3

it is good to use time module

import time
int(time.time())

1573708436

you can also use datetime module, but when you use strftime('%s'), but strftime convert time to your local time!

python2

from datetime import datetime
datetime.utcnow().strftime('%s')

python3

from datetime import datetime
datetime.utcnow().timestamp()

I created this function that will make your life easier:

    /// true - if the paths are Internet URLs, false - if the paths are local URLs, this is very important as this will be used to decide which separator will be used.
    /// </param>
    /// <param name="IsRelative">Just adds the separator at the beginning</param>
    /// <param name="IsFixInternal">Fix the paths from within (by removing duplicate separators and correcting the separators)</param>
    /// <param name="parts">The paths to combine</param>
    /// <returns>the combined path</returns>
    public static string PathCombine(bool IsURL , bool IsRelative , bool IsFixInternal , params string[] parts)
    {
        if (parts == null || parts.Length == 0) return string.Empty;
        char separator = IsURL ? '/' : '\\';

        if (parts.Length == 1 && IsFixInternal)

It works for URLs as well as normal paths.

Usage:

    // Fixes internal paths
    Console.WriteLine(PathCombine(true , true , true , @"\/\/folder 1\/\/\/\\/\folder2\///folder3\\/" , @"/\somefile.ext\/\//\"));
    // Result: /folder 1/folder2/folder3/somefile.ext

    // Doesn't fix internal paths
    Console.WriteLine(PathCombine(true , true , false , @"\/\/folder 1\/\/\/\\/\folder2\///folder3\\/" , @"/\somefile.ext\/\//\"));
    //result : /folder 1//////////folder2////folder3/somefile.ext

    // Don't worry about URL prefixes when fixing internal paths
    Console.WriteLine(PathCombine(true , false , true , @"/\/\/https:/\/\/\lul.com\/\/\/\\/\folder2\///folder3\\/" , @"/\somefile.ext\/\//\"));
    // Result: https://lul.com/folder2/folder3/somefile.ext

    Console.WriteLine(PathCombine(false , true , true , @"../../../\\..\...\./../somepath" , @"anotherpath"));
    // Result: \..\..\..\..\...\.\..\somepath\anotherpath
