You did not post the code generated by the compiler, so there' some guesswork here, but even without having seen it, one can say that this:

test rax, 1
jpe even

... has a 50% chance of mispredicting the branch, and that will come expensive.

The compiler almost certainly does both computations (which costs neglegibly more since the div/mod is quite long latency, so the multiply-add is "free") and follows up with a CMOV. Which, of course, has a zero percent chance of being mispredicted.

You should add return statement while you are forwarding or redirecting the flow.

Example:

if forwardind,

    request.getRequestDispatcher("/abs.jsp").forward(request, response);
    return;

if redirecting,

    response.sendRedirect(roundTripURI);
    return;

Please post your code,

<?php
    echo $_GET['link'];
?>

or

<?php
    echo $_REQUEST['link'];
?>

do work...

It depends on the host, but you probably simply can't (you can't on my shared host on Rackspace Cloud Sites - I asked them).

What you can do is set up an environment on your dev machine that roughly matches your shared host, and do all of your management through the command line locally. Then when everything is set (you've pulled in all the dependencies, updated, managed with git, etc.) you can "push" that to your shared host over (s)FTP.

If you want to extract the first number out of the input string, you can do-

public static String extractNumber(final String str) {                
    
    if(str == null || str.isEmpty()) return "";
    
    StringBuilder sb = new StringBuilder();
    boolean found = false;
    for(char c : str.toCharArray()){
        if(Character.isDigit(c)){
            sb.append(c);
            found = true;
        } else if(found){
            // If we already found a digit before and this char is not a digit, stop looping
            break;                
        }
    }
    
    return sb.toString();
}

Examples:

For input "123abc", the method above will return 123.

For "abc1000def", 1000.

For "555abc45", 555.

For "abc", will return an empty string.

If you have Python installed on your local machine (or you don't mind install one), here is a browser-independent workaround for local JSON file access problem that I use:

Transform the JSON file into a JavaScript by creating a function that returns the data as JavaScript object. Then you can load it with <script> tag and call the function to get the data you want.

Here comes the Python code

import json


def json2js(jsonfilepath, functionname='getData'):
    """function converting json file to javascript file: json_data -> json_data.js
    :param jsonfilepath: path to json file
    :param functionname: name of javascript function which will return the data
    :return None
    """
    # load json data
    with open(jsonfilepath,'r') as jsonfile:
        data = json.load(jsonfile)
    # write transformed javascript file
    with open(jsonfilepath+'.js', 'w') as jsfile:
        jsfile.write('function '+functionname+'(){return ')
        jsfile.write(json.dumps(data))
        jsfile.write(';}')

if __name__ == '__main__':
    from sys import argv
    l = len(argv)
    if l == 2:
        json2js(argv[1])
    elif l == 3:
        json2js(argv[1], argv[2])
    else:
        raise ValueError('Usage: python pathTo/json2js.py jsonfilepath [jsfunctionname]')

The best way around this is (and many other situations) in my experience, is to use cntlm which is a local no-authentication proxy which points to a remote authentication proxy. You can then just set WinHTTP to point to your local CNTLM (usually localhost:3128), and you can set CNTLM itself to point to the remote authentication proxy. CNTLM has a "magic NTLM dialect detection" option which generates password hashes to be put into the CNTLM configuration files.

Check your array index to see if it's accessed out of bound.

Once I accessed categories[0]. Later I changed the array name from categories to category but forgot to change the access point--from categories[0] to category[0], thus I also get this error.

JavaScript does a poor debug message. In your case, I reckon probably the access gets out of bound.

These may be a bit heavy, but they're flexible enough to sanitize whatever string into a "safe" en style filename or folder name (or heck, even scrubbed slugs and things if you bend it).

1) Building a full filename (with fallback name in case input is totally truncated):

str_file($raw_string, $word_separator, $file_extension, $fallback_name, $length);

2) Or using just the filter util without building a full filename (strict mode true will not allow [] or () in filename):

str_file_filter($string, $separator, $strict, $length);

3) And here are those functions:

// Returns filesystem-safe string after cleaning, filtering, and trimming input
function str_file_filter(
    $str,
    $sep = '_',
    $strict = false,
    $trim = 248) {

    $str = strip_tags(htmlspecialchars_decode(strtolower($str))); // lowercase -> decode -> strip tags
    $str = str_replace("%20", ' ', $str); // convert rogue %20s into spaces
    $str = preg_replace("/%[a-z0-9]{1,2}/i", '', $str); // remove hexy things
    $str = str_replace(" ", ' ', $str); // convert all nbsp into space
    $str = preg_replace("/&#?[a-z0-9]{2,8};/i", '', $str); // remove the other non-tag things
    $str = preg_replace("/\s+/", $sep, $str); // filter multiple spaces
    $str = preg_replace("/\.+/", '.', $str); // filter multiple periods
    $str = preg_replace("/^\.+/", '', $str); // trim leading period

    if ($strict) {
        $str = preg_replace("/([^\w\d\\" . $sep . ".])/", '', $str); // only allow words and digits
    } else {
        $str = preg_replace("/([^\w\d\\" . $sep . "\[\]\(\).])/", '', $str); // allow words, digits, [], and ()
    }

    $str = preg_replace("/\\" . $sep . "+/", $sep, $str); // filter multiple separators
    $str = substr($str, 0, $trim); // trim filename to desired length, note 255 char limit on windows

    return $str;
}


// Returns full file name including fallback and extension
function str_file(
    $str,
    $sep = '_',
    $ext = '',
    $default = '',
    $trim = 248) {

    // Run $str and/or $ext through filters to clean up strings
    $str = str_file_filter($str, $sep);
    $ext = '.' . str_file_filter($ext, '', true);

    // Default file name in case all chars are trimmed from $str, then ensure there is an id at tail
    if (empty($str) && empty($default)) {
        $str = 'no_name__' . date('Y-m-d_H-m_A') . '__' . uniqid();
    } elseif (empty($str)) {
        $str = $default;
    }

    // Return completed string
    if (!empty($ext)) {
        return $str . $ext;
    } else {
        return $str;
    }
}

So let's say some user input is: .....&lt;div&gt;&lt;/div&gt;<script></script>&amp; Weiß Göbel ?????File name %20 %20 %21 %2C Décor \/. /. . z \... y \...... x ./ “This name” is & 462^^ not &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; = that grrrreat -][09]()1234747) ???????-??-????????????

And we wanna convert it to something friendlier to make a tar.gz with a file name length of 255 chars. Here is an example use. Note: this example includes a malformed tar.gz extension as a proof of concept, you should still filter the ext after string is built against your whitelist(s).

$raw_str = '.....&lt;div&gt;&lt;/div&gt;<script></script>&amp; Weiß Göbel ?????File name  %20   %20 %21 %2C Décor  \/.  /. .  z \... y \...... x ./  “This name” is & 462^^ not &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; = that grrrreat -][09]()1234747) ???????-??-????????????';
$fallback_str = 'generated_' . date('Y-m-d_H-m_A');
$bad_extension = '....t&+++a()r.gz[]';

echo str_file($raw_str, '_', $bad_extension, $fallback_str);

The output would be: _wei_gbel_file_name_dcor_._._._z_._y_._x_._this_name_is_462_not_that_grrrreat_][09]()1234747)_.tar.gz

You can play with it here: https://3v4l.org/iSgi8

EDIT: updated script filter for   instead of space, updated 3v4l link

This is a bit of a Unix vs Linux battle. Most if not all Linux distributions have bash installed and ksh optional. Most Unix systems, like Solaris, AIX and HPUX have ksh as default.

Personally I always use ksh, I love the vi completion and I pretty much use Solaris for everything.

API level 14 introduced two new actions: ACTION_INSTALL_PACKAGE and ACTION_UNINSTALL_PACKAGE. Those actions allow you to pass EXTRA_RETURN_RESULT boolean extra to get an (un)installation result notification.

Example code for invoking the uninstall dialog:

String app_pkg_name = "com.example.app";
int UNINSTALL_REQUEST_CODE = 1;

Intent intent = new Intent(Intent.ACTION_UNINSTALL_PACKAGE);  
intent.setData(Uri.parse("package:" + app_pkg_name));  
intent.putExtra(Intent.EXTRA_RETURN_RESULT, true);
startActivityForResult(intent, UNINSTALL_REQUEST_CODE);

And receive the notification in your Activity#onActivityResult method:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == UNINSTALL_REQUEST_CODE) {
        if (resultCode == RESULT_OK) {
            Log.d("TAG", "onActivityResult: user accepted the (un)install");
        } else if (resultCode == RESULT_CANCELED) {
            Log.d("TAG", "onActivityResult: user canceled the (un)install");
        } else if (resultCode == RESULT_FIRST_USER) {
            Log.d("TAG", "onActivityResult: failed to (un)install");
        }
    }
}

This is succinct and readable:

"MyProperty" -in $MyObject.PSobject.Properties.Name

We can put it in a function:

function HasProperty($object, $propertyName)
{
    $propertyName -in $object.PSobject.Properties.Name
}

See the documentation on plt.axis(). This:

plt.axis('equal')

doesn't work because it changes the limits of the axis to make circles appear circular. What you want is:

plt.axis('square')

This creates a square plot with equal axes.

Mono comes with a wrapper, use theirs!

https://github.com/mono/mono/tree/master/mcs/class/Mono.Data.Sqlite/Mono.Data.Sqlite_2.0 gives code to wrap the actual SQLite dll ( http://www.sqlite.org/sqlite-shell-win32-x86-3071300.zip found on the download page http://www.sqlite.org/download.html/ ) in a .net friendly way. It works on Linux or Windows.

This seems the thinnest of all worlds, minimizing your dependence on third party libraries. If I had to do this project from scratch, this is the way I would do it.

There's no way around it except to store it. Memory paging should reduce potential issues there.

I would suggest instead of using a global variable called 'xml', do something more like this:

var dataStore = (function(){
    var xml;

    $.ajax({
      type: "GET",
      url: "test.xml",
      dataType: "xml",
      success : function(data) {
                    xml = data;
                }
    });

    return {getXml : function()
    {
        if (xml) return xml;
        // else show some error that it isn't loaded yet;
    }};
})();

then access it with:

$(dataStore.getXml()).find('something').attr('somethingElse');

I had a similar problem. I am posting my solution here because I believe it might help one of the commenters.

For me, the obstacle was that the page required a login and then gave me a new URL through javascript. Here is what I had to do:

curl -c cookiejar -g -O -J -L -F "j_username=username" -F "j_password=password" <URL>

Note that j_username and j_password is the name of the fields for my website's login form. You will have to open the source of the webpage to see what the 'name' of the username field and the 'name' of the password field is in your case. After that I go an html file with java script in which the new URL was embedded. After parsing this out just resubmit with the new URL:

curl -c cookiejar -g -O -J -L -F "j_username=username" -F "j_password=password" <NEWURL>

This can actually be done with only CSS, but the content inside the div must be absolutely positioned. The key is to use padding as a percentage and the box-sizing: border-box CSS attribute:

div {_x000D_
  border: 1px solid red;_x000D_
  width: 40%;_x000D_
  padding: 40%;_x000D_
  box-sizing: border-box;_x000D_
  position: relative;_x000D_
}_x000D_
p {_x000D_
  position: absolute;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
}

<div>_x000D_
  <p>Some unnecessary content.</p>_x000D_
</div>

Adjust percentages to your liking. Here is a JSFiddle

Dictionary is a key value pair. Catch Key by

dic["cat"] 

and assign its value like

dic["cat"] = 5

As you can see here, when you have more values there is a better approach.

http://jsfiddle.net/MsYGJ/

temp = {}
// Store each of the elements in an object keyed of of the name field.  If there is a collision (the name already exists) then it is just replaced with the most recent one.
for (var i = 0; i < varjson.DATA.length; i++) {
    temp[varjson.DATA[i].name] = varjson.DATA[i];
}
// Reset the array in varjson
varjson.DATA = [];
// Push each of the values back into the array.
for (var o in temp) {
    varjson.DATA.push(temp[o]);
}

Here we are creating an object with the name as the key. The value is simply the original object from the array. Doing this, each replacement is O(1) and there is no need to check if it already exists. You then pull each of the values out and repopulate the array.

NOTE
For smaller arrays, your approach is slightly faster.

NOTE 2
This will not preserve the original order.

   /* worked for me  */
     <div id="divid"> </div>
     <script type="text/javascript">
         var hold = document.getElementById("divid");
         var checkbox = document.createElement('input');
         checkbox.type = "checkbox";
         checkbox.name = "chkbox1";
         checkbox.id = "cbid";
         var label = document.createElement('label');
         var tn = document.createTextNode("Not A RoBot");
         label.htmlFor="cbid";
         label.appendChild(tn); 
         hold.appendChild(label);
         hold.appendChild(checkbox);
      </script>  

If you really need to be sure that now() has the same value you can run two queries (that will answer to your second question too, in that case you are asking to update last_monitor = to last_update but last_update hasn't been updated yet)

you could do something like:

mysql> update table set last_update=now() where id=1;
mysql> update table set last_monitor = last_update where id=1;

anyway I think that mysql is clever enough to ask for now() only once per query.

With quotes:

cat /etc/*-release | grep "PRETTY_NAME" | sed 's/PRETTY_NAME=//g'

gives output as:

"CentOS Linux 7 (Core)"

Without quotes:

cat /etc/*-release | grep "PRETTY_NAME" | sed 's/PRETTY_NAME=//g' | sed 's/"//g'

gives output as:

CentOS Linux 7 (Core)

Use the BitArray class.

int value = 3;
BitArray b = new BitArray(new int[] { value });

If you want to get an array for the bits, you can use the BitArray.CopyTo method with a bool[] array.

bool[] bits = new bool[b.Count];
b.CopyTo(bits, 0);

Note that the bits will be stored from least significant to most significant, so you may wish to use Array.Reverse.

And finally, if you want get 0s and 1s for each bit instead of booleans (I'm using a byte to store each bit; less wasteful than an int):

byte[] bitValues = bits.Select(bit => (byte)(bit ? 1 : 0)).ToArray();

To refresh menu from Fragment simply call:

getActivity().invalidateOptionsMenu();

When you add dependency in pom.xml , do a maven clean , and then maven build , it will add the jars into you project.

You can search dependency artifacts at http://mvnrepository.com/

And if it doesn't add jars it should give you errors which will mean that it is not able to fetch the jar, that could be due to broken repository or connection problems.

Well sometimes if it is one or two jars, better download them and add to build path , but with a lot of dependencies use maven.

I had to solve a similar problem--I wanted certain styles to only apply to mobile devices in landscape mode. Essentially the fonts and line spacing looked fine in every other context, so I just needed the one exception for mobile landscape. This media query worked perfectly:

@media all and (max-width: 600px) and (orientation:landscape) 
{
    /* styles here */
}

def visit_v2(device_code, camera_code):
    image1 = MultipartParam.from_file("files", "/home/yuzx/1.txt")
    image2 = MultipartParam.from_file("files", "/home/yuzx/2.txt")
    datagen, headers = multipart_encode([('device_code', device_code), ('position', 3), ('person_data', person_data), image1, image2])
    print "".join(datagen)
    if server_port == 80:
        port_str = ""
    else:
        port_str = ":%s" % (server_port,)
    url_str = "http://" + server_ip + port_str + "/adopen/device/visit_v2"
    headers['nothing'] = 'nothing'
    request = urllib2.Request(url_str, datagen, headers)
    try:
        response = urllib2.urlopen(request)
        resp = response.read()
        print "http_status =", response.code
        result = json.loads(resp)
        print resp
        return result
    except urllib2.HTTPError, e:
        print "http_status =", e.code
        print e.read()

trim() and other mentioned regular expression do not work for all types of whitespaces

i.e: Unicode Character 'LINE SEPARATOR' http://www.fileformat.info/info/unicode/char/2028/index.htm

Java functions Character.isWhitespace() covers all situations.

That is why already mentioned solution StringUtils.isWhitespace( String ) /or StringUtils.isBlank(String) should be used.

As best coding practices suggests, use setTimeout instead of setInterval.

function foo() {

    // your function code here

    setTimeout(foo, 5000);
}

foo();

Please note that this is NOT a recursive function. The function is not calling itself before it ends, it's calling a setTimeout function that will be later call the same function again.

Use the SETX command (note the 'x' suffix) to set variables that persist after the cmd window has been closed.

For example, to set an env var "foo" with value of "bar":

setx foo bar

Though it's worth reading the 'notes' that are displayed if you print the usage (setx /?), in particular:

2) On a local system, variables created or modified by this tool will be available in future command windows but not in the current CMD.exe command window.

3) On a remote system, variables created or modified by this tool will be available at the next logon session.

In PowerShell, the [Environment]::SetEnvironmentVariable command.

The error message is pretty self-explanatory: your application needs the Oracle Client installed on the machine it's running on. Your development PC already has it. Make sure your target PC has it, too.

Edit: The System.Data.OracleClient namespace is deprecated. Make sure you use the driver native to your database system, that would be ODP.NET from Oracle.

You can use the statement

- name: webfolder - Creates web folder
  file: path=/srv/www state=directory owner=www-data group=www-data mode=0775`

You can also use the tab character '\t' to represent a tab, instead of "\t".

char c ='t';
char c =(char)9;

Try:

extern int testlib(void);

As @Richard pointed out above, the onClick needs to have a capital 'C'.

$('#stop').click(function() {
     $('next').attr('onClick','stopMoving()');
}

I feel the simplest way would be

 from matplotlib import pyplot;
 from pylab import genfromtxt;  
 mat0 = genfromtxt("data0.txt");
 mat1 = genfromtxt("data1.txt");
 pyplot.plot(mat0[:,0], mat0[:,1], label = "data0");
 pyplot.plot(mat1[:,0], mat1[:,1], label = "data1");
 pyplot.legend();
 pyplot.show();

1. label is the string that is displayed on the legend
2. you can plot as many series of data points as possible before show() to plot all of them on the same graph This is the simple way to plot simple graphs. For other options in genfromtxt go to this url.

You can try this as well, it is easy to implement

TimeZone time2 = TimeZone.CurrentTimeZone;
DateTime test = time2.ToUniversalTime(DateTime.Now);
var singapore = TimeZoneInfo.FindSystemTimeZoneById("Singapore Standard Time");
var singaporetime = TimeZoneInfo.ConvertTimeFromUtc(test, singapore);

Change the text to which standard time you want to change.

Use TimeZone feature of C# to implement.

var Browser = new function () {
    var self = this;
    var nav = navigator.userAgent.toLowerCase();
    if (nav.indexOf('msie') != -1) {
        self.ie = {
            version: toFloat(nav.split('msie')[1])
        };
    };
};


if(Browser.ie && Browser.ie.version > 9)
{
    // do something
}

Please see this link for more information on setting the text size in code. Basically it says:

public void setTextSize (int unit, float size)

Since: API Level 1 Set the default text size to a given unit and value. See TypedValue for the possible dimension units. Related XML Attributes

android:textSize Parameters

unit The desired dimension unit.
size The desired size in the given units.

opt is new for ruby 1.9. The various options are documented in IO.new : www.ruby-doc.org/core/IO.html

As pointed out by litso, repeated use of the +-Operator in one expression can lead to XCode Beta hanging (just checked with XCode 6 Beta 5): Xcode 6 Beta not compiling

An alternative for multiline strings for now is to use an array of strings and reduce it with +:

var text = ["This is some text ",
            "over multiple lines"].reduce("", +)

Or, arguably simpler, using join:

var text = "".join(["This is some text ",
                    "over multiple lines"])

I personally didn't find any of these answers helpful. What worked in my case was giving the element float:none and position:relative. After that the element centered itself in the <td>.

Much thanks to all who posted their code. This is very useful.

I derived a similar solution to change the highlight color for grouped table view cells. Basically the UITableViewCell's selectedBackgroundView (not the backgroundView). Which even on iPhone OS 3.0 still needs this PITA solution, as far as I can tell...

The code below has the changes for rendering the highlight with a gradient instead of one solid color. Also the border rendering is removed. Enjoy.

Set overflow-y property to auto, or remove the property altogether if it is not inherited.

I realize this is really old, but I'm just getting started with ASP.NET MVC, so I thought I'd stick my two cents in:

• Request.IsAuthenticated tells you if the user is authenticated.
• Page.User.Identity gives you the identity of the logged-in user.

Try this:

;WITH CTE
AS
(
    SELECT DISTINCT
        M1.Product_ID Group_ID,
        M1.Product_ID
    FROM matches M1
        LEFT JOIN matches M2
            ON M1.Product_Id = M2.matching_Product_Id
    WHERE M2.matching_Product_Id IS NULL
    UNION ALL
    SELECT
        C.Group_ID,
        M.matching_Product_Id
    FROM CTE C
        JOIN matches M
            ON C.Product_ID = M.Product_ID
)
SELECT * FROM CTE ORDER BY Group_ID

You can use OPTION(MAXRECURSION n) to control recursion depth.

SQL FIDDLE DEMO

I have a similar problem and I resolved in this way:

@RequestMapping(value = "{siteCode}/**/{fileName}.{fileExtension}")
public HttpEntity<byte[]> getResource(@PathVariable String siteCode,
        @PathVariable String fileName, @PathVariable String fileExtension,
        HttpServletRequest req, HttpServletResponse response ) throws IOException {
    String fullPath = req.getPathInfo();
    // Calling http://localhost:8080/SiteXX/images/argentine/flag.jpg
    // fullPath conentent: /SiteXX/images/argentine/flag.jpg
}

Note that req.getPathInfo() will return the complete path (with {siteCode} and {fileName}.{fileExtension}) so you will have to process conveniently.

Using a service is the way to go. In route params you should only pass data that you want to be reflected in the browser URL bar.

See also https://angular.io/docs/ts/latest/cookbook/component-communication.html#!#bidirectional-service

The router shipped with RC.4 re-introduces data

constructor(private route: ActivatedRoute) {}

const routes: RouterConfig = [

When pip tells you that you already have protobuf, but PyCharm (or other) tells you that you don't have it, it means that pip and PyCharm are using a different Python interpreter. This is a very common issue, especially on a Mac, with no standard Python package management.

The best way to completely eliminate such issues is using a virtualenv per Python project, which is essentially a directory of Python packages and environment variable settings to isolate the Python environment of the project from everything else.

Create a virtualenv for your project like this:

cd project
virtualenv --distribute virtualenv -p /path/to/python/executable

This creates a directory called virtualenv inside your project. (Make sure to configure your VCS (for example Git) to ignore this directory.)

To install packages in this virtualenv, you need to activate the environment variable settings:

. virtualenv/bin/activate

Verify that pip will use the right Python executable inside the virtualenv, by running pip -V. It should tell you the Python library path used, which should be inside the virtualenv.

Now you can use pip to install protobuf as you did.

And finally, you need to make PyCharm use this virtualenv instead of the system libraries. Somewhere in the project settings you can configure an interpreter for the project, select the Python executable inside the virtualenv.

You can Enable DBMS_OUTPUT and set the buffer size. The buffer size can be between 1 and 1,000,000.

dbms_output.enable(buffer_size IN INTEGER DEFAULT 20000);
exec dbms_output.enable(1000000);

Check this

EDIT

As per the comment posted by Frank and Mat, you can also enable it with Null

exec dbms_output.enable(NULL);

buffer_size : Upper limit, in bytes, the amount of buffered information. Setting buffer_size to NULL specifies that there should be no limit. The maximum size is 1,000,000, and the minimum is 2,000 when the user specifies buffer_size (NOT NULL).

There's a simple way to this in any C-like language. The style is not Pythonic but works with pure Python:

def remove_html_markup(s):
    tag = False
    quote = False
    out = ""

    for c in s:
            if c == '<' and not quote:
                tag = True
            elif c == '>' and not quote:
                tag = False
            elif (c == '"' or c == "'") and tag:
                quote = not quote
            elif not tag:
                out = out + c

    return out

The idea based in a simple finite-state machine and is detailed explained here: http://youtu.be/2tu9LTDujbw

You can see it working here: http://youtu.be/HPkNPcYed9M?t=35s

Another way to delete the migration:

$ rails d migration SameMigrationNameAsUsedToGenerate

Use it before rake db:migrate is executed because changes in database will stay forever :) - or remove changes in Database manually

via constructor of a Runnable or Thread class

class MyThread extends Thread {

    private String to;

    public MyThread(String to) {
        this.to = to;
    }

    @Override
    public void run() {
        System.out.println("hello " + to);
    }
}

public static void main(String[] args) {
    new MyThread("world!").start();
}

You can use a Regular Expression with pattern matching to extract number from a string.

    String s="";
    Pattern p = Pattern.compile("\\d+");
    Matcher m = p.matcher("(1111)123-456-789"); //editText.getText().toString()                                      
    while (m.find()) {
    s=s+m.group(0);
    }
    System.out.println("............"+s);    

    Output : ............1111123456789

Just call the modal method(without passing any parameters) using jQuery selector.

Here is example:

$('#modal').modal();

This should do the trick...

'recalculate all open workbooks
Application.Calculate

'recalculate a specific worksheet
Worksheets(1).Calculate

' recalculate a specific range
Worksheets(1).Columns(1).Calculate

You can do this with jQuery. Using their selectors, you can select by attributes, such as type. This does, however, require that your users have Javascript turned on, and an additional file to download, but if it works...

This is documented behavior, why do you run CHECKIDENT if you recreate the table, in that case skip the step or use TRUNCATE (if you don't have FK relationships)

        try
        {
           // your code
        }
        catch (Exception w)
        {
            MessageDialog msgDialog = new MessageDialog(w.ToString());
        }

This works for me:

#content {_x000D_
  position: absolute; _x000D_
  left: 0; _x000D_
  right: 0; _x000D_
  margin-left: auto; _x000D_
  margin-right: auto; _x000D_
  width: 100px; /* Need a specific value to work */_x000D_
}

<body>_x000D_
  <div>_x000D_
    <div id="content">_x000D_
      I'm the content_x000D_
    </div>_x000D_
  </div>_x000D_
</body>

A simpler way to get the machine name without the \InstanceName is:

Lambda

Try to understand the difference between a normal def defined function and lambda function. This is a program that returns the cube of a given value:

# Python code to illustrate cube of a number 
# showing difference between def() and lambda(). 
def cube(y): 
    return y*y*y 
  
lambda_cube = lambda y: y*y*y 
  
# using the normally 
# defined function 
print(cube(5)) 
  
# using the lamda function 
print(lambda_cube(5)) 

output:

125
125

Without using Lambda:

• Here, both of them return the cube of a given number. But, while using def, we needed to define a function with a name cube and needed to pass a value to it. After execution, we also needed to return the result from where the function was called using the return keyword.

Using Lambda:

• Lambda definition does not include a “return” statement, it always contains an expression that is returned. We can also put a lambda definition anywhere a function is expected, and we don’t have to assign it to a variable at all. This is the simplicity of lambda functions.

Lambda functions can be used along with built-in functions like filter(), map() and reduce().

lambda() with filter()

The filter() function in Python takes in a function and a list as arguments. This offers an elegant way to filter out all the elements of a sequence “sequence”, for which the function returns True.

my_list = [1, 5, 4, 6, 8, 11, 3, 12]

new_list = list(filter(lambda x: (x%2 == 0) , my_list))

print(new_list)


ages = [13, 90, 17, 59, 21, 60, 5]

adults = list(filter(lambda age: age>18, ages)) 
  
print(adults) # above 18 yrs 

output:

[4, 6, 8, 12]
[90, 59, 21, 60]

lambda() with map()

The map() function in Python takes in a function and a list as an argument. The function is called with a lambda function and a list and a new list is returned which contains all the lambda modified items returned by that function for each item.

my_list = [1, 5, 4, 6, 8, 11, 3, 12]

new_list = list(map(lambda x: x * 2 , my_list))

print(new_list)


cities = ['novi sad', 'ljubljana', 'london', 'new york', 'paris'] 
  
# change all city names 
# to upper case and return the same 
uppered_cities = list(map(lambda city: str.upper(city), cities)) 
  
print(uppered_cities)

output:

[2, 10, 8, 12, 16, 22, 6, 24]
['NOVI SAD', 'LJUBLJANA', 'LONDON', 'NEW YORK', 'PARIS']

reduce

reduce() works differently than map() and filter(). It does not return a new list based on the function and iterable we've passed. Instead, it returns a single value.

Also, in Python 3 reduce() isn't a built-in function anymore, and it can be found in the functools module.

The syntax is:

reduce(function, sequence[, initial])

reduce() works by calling the function we passed for the first two items in the sequence. The result returned by the function is used in another call to function alongside with the next (third in this case), element.

The optional argument initial is used, when present, at the beginning of this "loop" with the first element in the first call to function. In a way, the initial element is the 0th element, before the first one, when provided.

lambda() with reduce()

The reduce() function in Python takes in a function and a list as an argument. The function is called with a lambda function and an iterable and a new reduced result is returned. This performs a repetitive operation over the pairs of the iterable.

from functools import reduce

my_list = [1, 1, 2, 3, 5, 8, 13, 21, 34] 

sum = reduce((lambda x, y: x + y), my_list) 

print(sum) # sum of a list
print("With an initial value: " + str(reduce(lambda x, y: x + y, my_list, 100)))

88
With an initial value: 188

These functions are convenience functions. They are there so you can avoid writing more cumbersome code, but avoid using both them and lambda expressions too much, because "you can", as it can often lead to illegible code that's hard to maintain. Use them only when it's absolutely clear what's going on as soon as you look at the function or lambda expression.

 sudo apt-get install default-jdk

That's all in ubuntu 11

if you are using centOS or Red Hat, you should first update SElinux. Execute the following statement

ausearch -c 'sshd' --raw | audit2allow -M my-sshd

then you need to execute

semodule -i my-sshd.pp

good luck

          builder.header(key, value);
      }
  }

To do it properly, you need to handle the exceptions.

        this.driver = drv;
        this.driver.switchTo().defaultContent();
        waitTimer(1, 1000);
        this.driver.switchTo().frame("BodyFrame1");
        LOGGER.info("IFrame1 constructor...");
    }

NOTE: You can see my entire working example here.

document.location isn't a string.

You're probably wanting to use document.location.href or document.location.pathname instead.

If you have some regular content, and not only one line of text, the only possible reason I know is to calculate margin.

Here is an example:

HTML

<div id="supercontainer">
  <div id="middlecontainer">
    <div class="common" id="first">first</div>
    <div id="container">
      <div class="common" id="second">second</div>
      <div class="common" id="third">third</div>
    </div>
  </div>
</div>

CSS

body {
  margin: 0;
  padding: 0;
}

.common {
  border: 1px solid black;
}

#supercontainer {
  width: 1200px;
  background: aqua;
  float: left;
}

#middlecontainer {
  float: left;
  width: 104px;
  margin: 0 549px;
}

#container {
  float: left;
}

#first {
  background: red;
  height: 102px;
  width: 50px;
  float: left;
}

#second {
  background: green;
  height: 50px;
  width: 50px;
}

#third {
  background: yellow;
  height: 50px;
  width: 50px;
}

So, #supercontainer is your "whole page" and its width is 1200px.

#middlecontainer is div with content of your site; it's width 102px. In case the width of content is known, you need to divide the page's size to 2, and subtract half of content's width from the result: 1200 / 2 - (102 / 2) = 549;

Yes, I'm also seeing that this is der grosse fail of CSS.

You have to use ':' colon instead of ';' semicolon.

As it stands now you try to execute the jar file which has not the execute bit set, hence the Permission denied.

And the variable must be CLASSPATH not classpath.

What are you expecting? The default Tomcat homepage? If so, you'll need to configure Eclipse to take control over from Tomcat.

Doubleclick the Tomcat server entry in the Servers tab, you'll get the server configuration. At the left column, under Server Locations, select Use Tomcat installation (note, when it is grayed out, read the section leading text! ;) ). This way Eclipse will take full control over Tomcat, this way you'll also be able to access the default Tomcat homepage with the Tomcat Manager when running from inside Eclipse. I only don't see how that's useful while developing using Eclipse.

The port number is not the problem. You would otherwise have gotten an exception in Tomcat's startup log, and the browser would show a browser-specific "Connection timed out" error page and thus not a Tomcat-specific error page which could impossibly be served when Tomcat was not up and running.

CSS 3 introduces rgba colour, and you can combine it with graphics for a backwards compatible solution.

I think you don't have to use sub query in this scenario.You can directly left outer join the DEPRMNT table .

While using Left Outer Join ,don't use columns in the RHS table of the join in the where condition, you ll get wrong output

Well, this will do it, but it's about as fast as it looks (roughly O(n*m), where n is the number of lines to display and m is the total number of lines in the file):

for /l %l in (1,1,10) do @for /f "tokens=1,2* delims=:" %a in ('findstr /n /r "^" filename ^| findstr /r "^%l:"') do @echo %b

Where "10" is the number of lines you want to print, and "filename" is the name of the file.

Use Timer for this

   private System.Windows.Forms.Timer timer1; 
   private int counter = 60;
   private void btnStart_Click_1(object sender, EventArgs e)
   {
        timer1 = new System.Windows.Forms.Timer();
        timer1.Tick += new EventHandler(timer1_Tick);
        timer1.Interval = 1000; // 1 second
        timer1.Start();
        lblCountDown.Text = counter.ToString();
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        counter--;
        if (counter == 0)
            timer1.Stop();
        lblCountDown.Text = counter.ToString();
    }

I recently had this problem and wrote a little tool, called Picklock, that avoids the problems of explicitly using the Java reflection API, two examples:

Calling methods, e.g. private void method(String s) - by Java reflection

Method method = targetClass.getDeclaredMethod("method", String.class);
method.setAccessible(true);
return method.invoke(targetObject, "mystring");

Calling methods, e.g. private void method(String s) - by Picklock

interface Accessible {
  void method(String s);
}

...
Accessible a = ObjectAccess.unlock(targetObject).features(Accessible.class);
a.method("mystring");

Setting fields, e.g. private BigInteger amount; - by Java reflection

Field field = targetClass.getDeclaredField("amount");
field.setAccessible(true);
field.set(object, BigInteger.valueOf(42));

Setting fields, e.g. private BigInteger amount; - by Picklock

interface Accessible {
  void setAmount(BigInteger amount);
}

...
Accessible a = ObjectAccess.unlock(targetObject).features(Accessible.class);
a.setAmount(BigInteger.valueOf(42));

Also worth noting you can use 'em' as well as 'px' - blogs and text based sites do it because then the browser makes layout decisions more relative to the text content.

On Wordpress twentysixteen I wanted my tagline to display on mobiles as well as desktops, so I put this in my child theme style.css

@media screen and (max-width:59em){
    p.site-description {
        display:    block;
    }
}

Somewhat easy to make add or remove HTML5 validation to fieldsets.

 $('form').each(function(){

    // CLEAR OUT ALL THE HTML5 REQUIRED ATTRS
    $(this).find('.required').attr('required', false);

    // ADD THEM BACK TO THE CURRENT FIELDSET
    // I'M JUST USING A CLASS TO IDENTIFY REQUIRED FIELDS
    $(this).find('fieldset.current .required').attr('required', true);

    $(this).submit(function(){

        var current     = $(this).find('fieldset.current')
        var next        = $(current).next()

        // MOVE THE CURRENT MARKER
        $(current).removeClass('current');
        $(next).addClass('current');

        // ADD THE REQUIRED TAGS TO THE NEXT PART
        // NO NEED TO REMOVE THE OLD ONES
        // SINCE THEY SHOULD BE FILLED OUT CORRECTLY
        $(next).find('.required').attr('required', true);

    });

});

begin() returns the first pair, (precisely, an iterator to the first pair, and you can access the key/value as ->first and ->second of that iterator)

My solution that does not involve any other library and it works with diff > 24h

var momentInSeconds = moment.duration(n,'seconds')
console.log(("0" + Math.floor(momentInSeconds.asHours())).slice(-2) + ':' + ("0" + momentInSeconds.minutes()).slice(-2) + ':' + ("0" + momentInSeconds.seconds()).slice(-2))

Note that the answer provided by ViNce does NOT include the end date for the period.

If you are using PHP 5.3+, your best bet is to use a function like this:

/**
 * Generate an array of string dates between 2 dates
 *
 * @param string $start Start date
 * @param string $end End date
 * @param string $format Output format (Default: Y-m-d)
 *
 * @return array
 */
function getDatesFromRange($start, $end, $format = 'Y-m-d') {
    $array = array();
    $interval = new DateInterval('P1D');

    $realEnd = new DateTime($end);
    $realEnd->add($interval);

    $period = new DatePeriod(new DateTime($start), $interval, $realEnd);

    foreach($period as $date) { 
        $array[] = $date->format($format); 
    }

    return $array;
}

Then, you would call the function as expected:

getDatesFromRange('2010-10-01', '2010-10-05');

Run demo

Note about DatePeriod class: You can use the 4th parameter of DatePeriod to exclude the start date (DatePeriod::EXCLUDE_START_DATE) but you cannot, at this time, include the end date.

Is there a method for clearing the .thens of a JavaScript Promise instance?

No. Not in ECMAScript 6 at least. Promises (and their then handlers) are uncancellable by default (unfortunately). There is a bit of discussion on es-discuss (e.g. here) about how to do this in the right way, but whatever approach will win it won't land in ES6.

The current standpoint is that subclassing will allow to create cancellable promises using your own implementation (not sure how well that'll work).

Until the language commitee has figured out the best way (ES7 hopefully?) you can still use userland Promise implementations, many of which feature cancellation.

Current discussion is in the https://github.com/domenic/cancelable-promise and https://github.com/bergus/promise-cancellation drafts.

As has already been mentioned, if you control the server side then it should be possible to send the initial request headers back to the client in the initial response.

In Express, for example, the following works:

app.get('/somepage', (req, res) => { res.render('somepage.hbs', {headers: req.headers}); }) The headers are then available within the template, so could be hidden visually but included in the markup and read by clientside javascript.

No, what you are looking for would be called a parent selector. CSS has none; they have been proposed multiple times but I know of no existing or forthcoming standard including them. You are correct that you would need to use something like jQuery or use additional class annotations to achieve the effect you want.

Here are some similar questions with similar results:

• Is there a CSS parent selector?
• CSS Parent/Ancestor Selector
• Complex CSS selector for parent of active child

But again main doubt why TextView resource id it needs?

Look at the constructor and the params.

public ArrayAdapter (Context context, int resource, int textViewResourceId, T[] objects)

Added in API level 1 Constructor

Parameters

context The current context.

resource The resource ID for a layout file containing a layout to use when instantiating views.

textViewResourceId The id of the TextView within the layout resource to be populated objects The objects to represent in the ListView.

android.R.id.text1 refers to the id of text in android resource. So you need not have the one in your activity.

Here's the full list

http://developer.android.com/reference/android/R.id.html

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
        android.R.layout.simple_list_item_1, android.R.id.text1, values);

this refers to activity context

android.R.layout.simple_list_item_1 simple_list_item_1 is the layout in android.R.layout.

android.R.id.text1 refers to the android resource id.

values is a string array from the link you provided

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

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

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

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

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

Correct solution is to copy or install to /usr/local/bin not /usr/bin.This is due to System Integrity Protection (SIP). SIP makes /usr/bin read-only but leaves /usr/local as read-write.

SIP should not be disabled as stated in the answer above because it adds another layer of protection against malware gaining root access. Here is a complete explanation of what SIP does and why it is useful.

As suggested in this answer one should not disable SIP (rootless mode) "It is not recommended to disable rootless mode! The best practice is to install custom stuff to "/usr/local" only."

The easiest way would be to use a library like this one and specifically you want noStrings to be true

    export class CustomValidator{   // Number only validation   
      static numeric(control: AbstractControl) {
        let val = control.value;

        const hasError = validate({val: val}, {val: {numericality: {noStrings: true}}});

        if (hasError) return null;

        return val;   
      } 
    }

The above answers will position the inner element at the top of the overflow element even if it's in view inside the overflow element. I didn't want that so I modified it to not change the scroll position if the element is in view.

jQuery.fn.scrollTo = function(elem, speed) {
    var $this = jQuery(this);
    var $this_top = $this.offset().top;
    var $this_bottom = $this_top + $this.height();
    var $elem = jQuery(elem);
    var $elem_top = $elem.offset().top;
    var $elem_bottom = $elem_top + $elem.height();

    if ($elem_top > $this_top && $elem_bottom < $this_bottom) {
        // in view so don't do anything
        return;
    }
    var new_scroll_top;
    if ($elem_top < $this_top) {
        new_scroll_top = {scrollTop: $this.scrollTop() - $this_top + $elem_top};
    } else {
        new_scroll_top = {scrollTop: $elem_bottom - $this_bottom + $this.scrollTop()};
    }
    $this.animate(new_scroll_top, speed === undefined ? 100 : speed);
    return this;
};

When you call the function in a static context, $this simply doesn't exist.

You would have to use this::xyz() instead.

To find out what context you're in when a function can be called both statically and in an object instance, a good approach is outlined in this question: How to tell whether I’m static or an object?

If you want to convert an Array of digits to a single number just use:

Number(arrayOfDigits.join(''));

Example

const arrayOfDigits = [1,2,3,4,5];

const singleNumber = Number(arrayOfDigits.join(''));

console.log(singleNumber); //12345

Technically, there's no built-in command to edit an existing symbolic link. It can be easily achieved with a few short commands.

Here's a little bash/zsh function I wrote to update an existing symbolic link:

# -----------------------------------------
# Edit an existing symbolic link
#
# @1 = Name of symbolic link to edit
# @2 = Full destination path to update existing symlink with 
# -----------------------------------------
function edit-symlink () {
    if [ -z "$1" ]; then
        echo "Name of symbolic link you would like to edit:"
        read LINK
    else
        LINK="$1"
    fi
    LINKTMP="$LINK-tmp"
    if [ -z "$2" ]; then
        echo "Full destination path to update existing symlink with:"
        read DEST
    else
        DEST="$2"
    fi
    ln -s $DEST $LINKTMP
    rm $LINK
    mv $LINKTMP $LINK
    printf "Updated $LINK to point to new destination -> $DEST"
}

Suppose your "Don't Check" list is on Sheet2 in cells A1:A100, say, and your current client IDs are in Sheet1 in Column A.

What you would do is:

1. Select the whole data table you want conditionally formatted in Sheet1
2. Click Conditional Formatting > New Rule > Use a Formula to determine which cells to format
3. In the formula bar, type in =ISNUMBER(MATCH($A1,Sheet2!$A$1:$A$100,0)) and select how you want those rows formatted

And that should do the trick.

you can put the css folder inside the assest folder(you name it any name) in the directory of your project as:

- ci_app
- application 
- views      
- assets 
  - css

... when you want to load that file in a page, you can use base_url()function as this way: <head> <link rel='stylesheet' href='<?php echo base_url();?>assets/css/style.css'> </head> and you are sure to add base_url of your project in the config.php file as this:

$config['base_url'] = 'http://localhost/ci_app';

Your system is missing the mysqlnd driver!

If you are able to install new packages on your (Debian/Ubuntu-based) server, install the driver:

sudo apt-get install php5-mysqlnd

and then restart your web server:

sudo /etc/init.d/apache2 restart

apt-get install python2.7 will work on debian-like linuxes. The python website describes a whole bunch of other ways to get Python.

If you are debugging T4 templates, then this happens all the time. My solution (before MS fixes this) would be just to kill this process:

Task Manager --> User --> T4VSHostProcess.exe

This process only comes up when you debug a T4 template, not when you run one.

If you are developing an OSGi system I would recommend you to download the "bundlefied" version from Springsource Enterprise Bundle Repository.

Otherwise its ok to use a regular jar-file containing the javax.persistence package

That part is called "fragment" and you can get it in this way:

$url=parse_url("http://domain.com/site/gallery/1#photo45 ");
echo $url["fragment"]; //This variable contains the fragment

package main

import (
"fmt"
)

func main() {
    var str1 = "string1"
    var str2 = "string2"
    result := make([]byte, 0)
    result = append(result, []byte(str1)...)
    result = append(result, []byte(str2)...)
    result = append(result, []byte(str1)...)
    result = append(result, []byte(str2)...)

    fmt.Println(string(result))
}

JSON to python object

The follwing code creates dynamic attributes with the objects keys recursively.

JSON object - fb_data.json:

{
    "name": "John Smith",
    "hometown": {
        "name": "New York",
        "id": 123
    },
    "list": [
        "a",
        "b",
        "c",
        1,
        {
            "key": 1
        }
    ],
    "object": {
        "key": {
            "key": 1
        }
    }
}

On the conversion we have 3 cases:

• lists
• dicts (new object)
• bool, int, float and str

import json


class AppConfiguration(object):
    def __init__(self, data=None):
        if data is None:
            with open("fb_data.json") as fh:
                data = json.loads(fh.read())
        else:
            data = dict(data)

        for key, val in data.items():
            setattr(self, key, self.compute_attr_value(val))

    def compute_attr_value(self, value):
        if isinstance(value, list):
            return [self.compute_attr_value(x) for x in value]
        elif isinstance(value, dict):
            return AppConfiguration(value)
        else:
            return value


if __name__ == "__main__":
    instance = AppConfiguration()

    print(instance.name)
    print(instance.hometown.name)
    print(instance.hometown.id)
    print(instance.list[4].key)
    print(instance.object.key.key)

Now the key, value pairs are attributes - objects.

output:

John Smith
New York
123

NOTE: The below solution no longer works on iOS 13+ devices - it will return garbage data.

Please use following code instead:

+ (NSString *)hexadecimalStringFromData:(NSData *)data
{
  NSUInteger dataLength = data.length;
  if (dataLength == 0) {
    return nil;
  }

  const unsigned char *dataBuffer = (const unsigned char *)data.bytes;
  NSMutableString *hexString  = [NSMutableString stringWithCapacity:(dataLength * 2)];
  for (int i = 0; i < dataLength; ++i) {
    [hexString appendFormat:@"%02x", dataBuffer[i]];
  }
  return [hexString copy];
}

Solution that worked prior to iOS 13:

Objective-C

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken 
{
    NSString *token = [[deviceToken description] stringByTrimmingCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@"<>"]];
    token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
    NSLog(@"this will return '32 bytes' in iOS 13+ rather than the token", token);
} 

Swift 3.0

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
{
    let tokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
    print("this will return '32 bytes' in iOS 13+ rather than the token \(tokenString)")
}

If you want to rotate a vector you should construct what is known as a rotation matrix.

Rotation in 2D

Say you want to rotate a vector or a point by ?, then trigonometry states that the new coordinates are

    x' = x cos ? - y sin ?
    y' = x sin ? + y cos ?

To demo this, let's take the cardinal axes X and Y; when we rotate the X-axis 90° counter-clockwise, we should end up with the X-axis transformed into Y-axis. Consider

    Unit vector along X axis = <1, 0>
    x' = 1 cos 90 - 0 sin 90 = 0
    y' = 1 sin 90 + 0 cos 90 = 1
    New coordinates of the vector, <x', y'> = <0, 1>  ?  Y-axis

When you understand this, creating a matrix to do this becomes simple. A matrix is just a mathematical tool to perform this in a comfortable, generalized manner so that various transformations like rotation, scale and translation (moving) can be combined and performed in a single step, using one common method. From linear algebra, to rotate a point or vector in 2D, the matrix to be built is

    |cos ?   -sin ?| |x| = |x cos ? - y sin ?| = |x'|
    |sin ?    cos ?| |y|   |x sin ? + y cos ?|   |y'|

Rotation in 3D

That works in 2D, while in 3D we need to take in to account the third axis. Rotating a vector around the origin (a point) in 2D simply means rotating it around the Z-axis (a line) in 3D; since we're rotating around Z-axis, its coordinate should be kept constant i.e. 0° (rotation happens on the XY plane in 3D). In 3D rotating around the Z-axis would be

    |cos ?   -sin ?   0| |x|   |x cos ? - y sin ?|   |x'|
    |sin ?    cos ?   0| |y| = |x sin ? + y cos ?| = |y'|
    |  0       0      1| |z|   |        z        |   |z'|

around the Y-axis would be

    | cos ?    0   sin ?| |x|   | x cos ? + z sin ?|   |x'|
    |   0      1       0| |y| = |         y        | = |y'|
    |-sin ?    0   cos ?| |z|   |-x sin ? + z cos ?|   |z'|

around the X-axis would be

    |1     0           0| |x|   |        x        |   |x'|
    |0   cos ?    -sin ?| |y| = |y cos ? - z sin ?| = |y'|
    |0   sin ?     cos ?| |z|   |y sin ? + z cos ?|   |z'|

Note 1: axis around which rotation is done has no sine or cosine elements in the matrix.

Note 2: This method of performing rotations follows the Euler angle rotation system, which is simple to teach and easy to grasp. This works perfectly fine for 2D and for simple 3D cases; but when rotation needs to be performed around all three axes at the same time then Euler angles may not be sufficient due to an inherent deficiency in this system which manifests itself as Gimbal lock. People resort to Quaternions in such situations, which is more advanced than this but doesn't suffer from Gimbal locks when used correctly.

I hope this clarifies basic rotation.

Rotation not Revolution

The aforementioned matrices rotate an object at a distance r = v(x² + y²) from the origin along a circle of radius r; lookup polar coordinates to know why. This rotation will be with respect to the world space origin a.k.a revolution. Usually we need to rotate an object around its own frame/pivot and not around the world's i.e. local origin. This can also be seen as a special case where r = 0. Since not all objects are at the world origin, simply rotating using these matrices will not give the desired result of rotating around the object's own frame. You'd first translate (move) the object to world origin (so that the object's origin would align with the world's, thereby making r = 0), perform the rotation with one (or more) of these matrices and then translate it back again to its previous location. The order in which the transforms are applied matters. Combining multiple transforms together is called concatenation or composition.

Composition

I urge you to read about linear and affine transformations and their composition to perform multiple transformations in one shot, before playing with transformations in code. Without understanding the basic maths behind it, debugging transformations would be a nightmare. I found this lecture video to be a very good resource. Another resource is this tutorial on transformations that aims to be intuitive and illustrates the ideas with animation (caveat: authored by me!).

Rotation around Arbitrary Vector

A product of the aforementioned matrices should be enough if you only need rotations around cardinal axes (X, Y or Z) like in the question posted. However, in many situations you might want to rotate around an arbitrary axis/vector. The Rodrigues' formula (a.k.a. axis-angle formula) is a commonly prescribed solution to this problem. However, resort to it only if you’re stuck with just vectors and matrices. If you're using Quaternions, just build a quaternion with the required vector and angle. Quaternions are a superior alternative for storing and manipulating 3D rotations; it's compact and fast e.g. concatenating two rotations in axis-angle representation is fairly expensive, moderate with matrices but cheap in quaternions. Usually all rotation manipulations are done with quaternions and as the last step converted to matrices when uploading to the rendering pipeline. See Understanding Quaternions for a decent primer on quaternions.

Sometimes because you are resolving your interface in ContainerBootstraper.cs it's very difficult to catch the error. In my case there was an error in resolving the implementation of the interface I've injected to the api controller. I couldn't find the error because I have resolve the interface in my bootstraperContainer like this: container.RegisterType<IInterfaceApi, MyInterfaceImplementaionHelper>(new ContainerControlledLifetimeManager());
then I've adde the following line in my bootstrap container : container.RegisterType<MyController>(); so when I compile the project , compiler complained and stopped in above line and showed the error.

Most opensource projects use GetText for this purpose. I don't know how and if it's ever been used on a .Net project before.

A solution to this problem could be to apply the filters on controller side :

$scope.tags = $filter('lowercase')($scope.tags);

Don't forget to declare $filter as dependency.

I know this isn't a direct answer to your question, but you could also consider using clip-path, as in this question: https://stackoverflow.com/a/18208889/23341.

The correct solution is:

SELECT o.*
FROM `Persons` o                    # 'o' from 'oldest person in group'
  LEFT JOIN `Persons` b             # 'b' from 'bigger age'
      ON o.Group = b.Group AND o.Age < b.Age
WHERE b.Age is NULL                 # bigger age not found

How it works:

It matches each row from o with all the rows from b having the same value in column Group and a bigger value in column Age. Any row from o not having the maximum value of its group in column Age will match one or more rows from b.

The LEFT JOIN makes it match the oldest person in group (including the persons that are alone in their group) with a row full of NULLs from b ('no biggest age in the group').
Using INNER JOIN makes these rows not matching and they are ignored.

The WHERE clause keeps only the rows having NULLs in the fields extracted from b. They are the oldest persons from each group.

If you have a browser that doesn't support the calc expression, it's not hard to mimic with jQuery:

$('#yourEl').css('width', '100%').css('width', '-=100px');

It's much easier to let jQuery handle the relative calculation than doing it yourself.

I have crossed with this issue many times, but I didnt try to dig deeper about it. Now I understand the main issue.

This time my problem was importing Serializers ( django and restframework ) from different modules such as the following :

from rest_framework import serializers

from common import serializers as srlz
from prices import models as mdlpri

# the line below was the problem 'srlzprod'
from products import serializers as srlzprod

I was getting a problem like this :

from product import serializers as srlzprod
ModuleNotFoundError: No module named 'product'

What I wanted to accomplished was the following :

class CampaignsProductsSerializers(srlz.DynamicFieldsModelSerializer):
    bank_name = serializers.CharField(trim_whitespace=True,)
    coupon_type = serializers.SerializerMethodField()
    promotion_description = serializers.SerializerMethodField()

    # the nested relation of the line below
    product = srlzprod.ProductsSerializers(fields=['id','name',],read_only=True,)

So, as mentioned by the lines above how to solve it ( top-level import ), I proceed to do the following changes :

# change
product = srlzprod.ProductsSerializers(fields=['id','name',],read_only=True,)
# by 
product = serializers.SerializerMethodField()

# and create the following method and call from there the required serializer class
def get_product(self, obj):
        from products import serializers as srlzprod
        p_fields = ['id', 'name', ]
        return srlzprod.ProductsSerializers(
            obj.product, fields=p_fields, many=False,
        ).data

Therefore, django runserver was executed without problems :

./project/settings/manage.py runserver 0:8002 --settings=settings_development_mlazo
Performing system checks...

System check identified no issues (0 silenced).
April 25, 2020 - 13:31:56
Django version 2.0.7, using settings 'settings_development_mlazo'
Starting development server at http://0:8002/
Quit the server with CONTROL-C.

Final state of the code lines was the following :

from rest_framework import serializers

from common import serializers as srlz
from prices import models as mdlpri

class CampaignsProductsSerializers(srlz.DynamicFieldsModelSerializer):
    bank_name = serializers.CharField(trim_whitespace=True,)
    coupon_type = serializers.SerializerMethodField()
    promotion_description = serializers.SerializerMethodField()
    product = serializers.SerializerMethodField()

    class Meta:
        model = mdlpri.CampaignsProducts
        fields = '__all__'

    def get_product(self, obj):
        from products import serializers as srlzprod
        p_fields = ['id', 'name', ]
        return srlzprod.ProductsSerializers(
            obj.product, fields=p_fields, many=False,
        ).data

Hope this could be helpful for everybody else.

Greetings,

Just to suggest another way without using if statements, you can use the get() method for DataFrames. For performing the sum based on the question:

df['sum'] = df.get('A', df['B']) + df['C']

The DataFrame get method has similar behavior as python dictionaries.

List.clear would remove the elements without reducing the capacity of the list.

groovy:000> mylist = [1,2,3,4,5,6,7,8,9,10,11,12]
===> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
groovy:000> mylist.elementData.length
===> 12
groovy:000> mylist.elementData
===> [Ljava.lang.Object;@19d6af
groovy:000> mylist.clear()
===> null
groovy:000> mylist.elementData.length
===> 12
groovy:000> mylist.elementData
===> [Ljava.lang.Object;@19d6af
groovy:000> mylist = new ArrayList();
===> []
groovy:000> mylist.elementData
===> [Ljava.lang.Object;@2bfdff
groovy:000> mylist.elementData.length
===> 10

Here mylist got cleared, the references to the elements held by it got nulled out, but it keeps the same backing array. Then mylist was reinitialized and got a new backing array, the old one got GCed. So one way holds onto memory, the other one throws out its memory and gets reallocated from scratch (with the default capacity). Which is better depends on whether you want to reduce garbage-collection churn or minimize the current amount of unused memory. Whether the list sticks around long enough to be moved out of Eden might be a factor in deciding which is faster (because that might make garbage-collecting it more expensive).

You want the argument unpacking operator *.

• TortoiseMerge (part of ToroiseSVN) is much better than kdiff3 (I use both and can compare);
• p4merge (from Perforce) works also very well;
• Diffuse isn't so bad;
• Diffmerge from SourceGear has only one flaw in handling UTF8-files without BOM, making in unusable for this case.

This is quite late, but interestingly never mentioned yet.

select stuff(x,len(x),1,'')

ie:

take a string x
go to its last character
remove one character
add nothing

Your mistake is looking for range, which gives you the range of a vector, for example:

range(c(10, -5, 100))

gives

 -5 100

Instead, look at the : operator to give sequences (with a step size of one):

1:100

or you can use the seq function to have a bit more control. For example,

##Step size of 2
seq(1, 100, by=2)

or

##length.out: desired length of the sequence
seq(1, 100, length.out=5)

Dont forget to add this code in your MainActivity.java:

MainActivity.java

mShaker = new ShakeListener(this);
mShaker.setOnShakeListener(new ShakeListener.OnShakeListener () {
    public void onShake() {
        Toast.makeText(MainActivity.this, "Shake " , Toast.LENGTH_LONG).show();        
    }
});

@Override
protected void onResume() {
    super.onResume();
    mShaker.resume();
}

@Override
protected void onPause() {
    super.onPause();
    mShaker.pause();
}

Or I give you a link about this stuff.

If the requested commit is in the pull requests of the remote repo, you can get it by its ID:

# Add the remote repo path, let's call it 'upstream':
git remote add upstream https://github.com/repo/project.git

# checkout the pull ID, for example ID '60':
git fetch upstream pull/60/head && git checkout FETCH_HEAD

Ex: In web.xml file the tag

<context-param>
        <param-name>chatpropertyfile</param-name>
        <!--  Name of the chat properties file. It contains the name and description                   of rooms.-->     
        <param-value>chat.properties</param-value>
    </context-param>

And chat.properties you can declare your properties like this

For Ex :

Jsp = Discussion about JSP can be made here.
Java = Talk about java and related technologies like J2EE.
ASP = Discuss about Active Server Pages related technologies like VBScript and JScript etc.
Web_Designing = Any discussion related to HTML, JavaScript, DHTML etc.
StartUp = Startup chat room. Chatter is added to this after he logs in.

For an already running container, you can do:

dockerId=$(docker inspect -f {{.Id}} [docker_id_or_name])

cd /var/lib/docker/btrfs/subvolumes/$dockerId

You need to be root in order to cd into that dir. If you are not root, try 'sudo su' before running the command.

Use cursors.

A cursor can be thought of like a buffered reader, when reading through a document. If you think of each row as a line in a document, then you would read the next line, perform your operations, and then advance the cursor.

eloone did it file by file with

git checkout <commit-hash> <filename>

but you could checkout all files more easily by doing

git checkout <commit-hash> .

Add the image to Your project by clicking File -> "Add Files to ...".

Then choose the image in ImageView properties (Utilities -> Attributes Inspector).

As far as I know, there isn't any built-in method for primitives. But something as simple as this should do the trick:

public int gcd(int a, int b) {
   if (b==0) return a;
   return gcd(b,a%b);
}

You can also one-line it if you're into that sort of thing:

public int gcd(int a, int b) { return b==0 ? a : gcd(b, a%b); }

It should be noted that there is absolutely no difference between the two as they compile to the same byte code.

You can try running a simple web server based on Twisted

Is there an easy way to convert jQuery code to regular javascript?

No, especially if:

understanding the examples of javascript solutions written in jQuery [is] hard.

JQuery and all the frameworks tend to make understanding the code easier. If that's difficult to understand, then vanilla javascript will be torture :)

Just looking at the documentation it seems you should just declare a buffer of type []byte and pass it to read which will then read up to that many characters and return the number of characters actually read (and an error).

The docs say

Read reads up to len(b) bytes from the File. It returns the number of bytes read and an Error, if any. EOF is signaled by a zero count with err set to EOF.

Does that not work?

EDIT: Also, I think you should perhaps use the Reader/Writer interfaces declared in the bufio package instead of using os package.

Find/search for file "xampp-control.ini" where you installed XAMPP server (e.g., D:\Server or C:\xampp).

Then edit in n the [Autostart] section:

Apache=1
MySQL=1
FileZilla=0
Mercury=0
Tomcat=0

Where 1 = true and 0 = false

That's so simple.

I agree with other answers that you are doing something weird here. You have a list containing a string with multiple entries that are themselves integers that you are comparing to an integer id.

This is almost surely not what you should be doing. You probably should be taking input and converting it to integers before storing in your list. You could do that with:

input = '350882 348521 350166\r\n'
list.append([int(x) for x in input.split()])

Then your test will pass. If you really are sure you don't want to do what you're currently doing, the following should do what you want, which is to not add the new id that already exists:

list = ['350882 348521 350166\r\n']
id = 348521
if id not in [int(y) for x in list for y in x.split()]:
    list.append(id)
print list

Input elements have a property called disabled. When the form submits, just run some code like this:

var myInput = document.getElementById('myInput');
myInput.disabled = true;

Crude but working way will be to force the scroll back to top, thus effectively disabling scrolling:

var _stopScroll = false;
window.onload = function(event) {
    document.onscroll = function(ev) {
        if (_stopScroll) {
            document.body.scrollTop = "0px";
        }
    }
};

When you open the lightbox raise the flag and when closing it,lower the flag.

Live test case.

I did it like this

var owner = new Form { TopMost = true };
Task.Delay(30000).ContinueWith(t => {
owner.Invoke(new Action(()=>
{
      if (!owner.IsDisposed)
      {
          owner.Close();
      }
   }));
});
var dialogRes =  MessageBox.Show(owner, msg, "Info", MessageBoxButtons.YesNo, MessageBoxIcon.Information);

I make it simple, if the layout is same i just put the intent it.

My code like this:

public class RegistrationMenuActivity extends AppCompatActivity implements View.OnClickListener {


    private Button btnCertificate, btnSeminarKit;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_registration_menu);

        initClick();
    }

    private void initClick() {
        btnCertificate = (Button) findViewById(R.id.btn_Certificate);
        btnCertificate.setOnClickListener(this);

        btnSeminarKit = (Button) findViewById(R.id.btn_SeminarKit);
        btnSeminarKit.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.btn_Certificate:
                break;
            case R.id.btn_SeminarKit:
                break;
        }
        Intent intent = new Intent(RegistrationMenuActivity.this, ScanQRCodeActivity.class);
        startActivity(intent);
    }
}

System.gc(); 

Runs the garbage collector.

Calling the gc method suggests that the Java Virtual Machine expend effort toward recycling unused objects in order to make the memory they currently occupy available for quick reuse. When control returns from the method call, the Java Virtual Machine has made a best effort to reclaim space from all discarded objects.

Not recommended.

Edit: I wrote the original response in 2009. It's now 2015.

Garbage collectors have gotten steadily better in the ~20 years Java's been around. At this point, if you're manually calling the garbage collector, you may want to consider other approaches:

• If you're forcing GC on a limited number of machines, it may be worth having a load balancer point away from the current machine, waiting for it to finish serving to connected clients, timeout after some period for hanging connections, and then just hard-restart the JVM. This is a terrible solution, but if you're looking at System.gc(), forced-restarts may be a possible stopgap.
• Consider using a different garbage collector. For example, the (new in the last six years) G1 collector is a low-pause model; it uses more CPU overall, but does it's best to never force a hard-stop on execution. Since server CPUs now almost all have multiple cores, this is A Really Good Tradeoff to have available.
• Look at your flags tuning memory use. Especially in newer versions of Java, if you don't have that many long-term running objects, consider bumping up the size of newgen in the heap. newgen (young) is where new objects are allocated. For a webserver, everything created for a request is put here, and if this space is too small, Java will spend extra time upgrading the objects to longer-lived memory, where they're more expensive to kill. (If newgen is slightly too small, you're going to pay for it.) For example, in G1:
  • XX:G1NewSizePercent (defaults to 5; probably doesn't matter.)
  • XX:G1MaxNewSizePercent (defaults to 60; probably raise this.)
• Consider telling the garbage collector you're not okay with a longer pause. This will cause more-frequent GC runs, to allow the system to keep the rest of it's constraints. In G1:
  • XX:MaxGCPauseMillis (defaults to 200.)

You can use jQuery's isEmptyObject() to check whether the array contains elements or not.

var testArray=[1,2,3,4,5]; 
var testArray1=[];
console.log(jQuery.isEmptyObject(testArray)); //false
console.log(jQuery.isEmptyObject(testArray1)); //true 

Source: https://api.jquery.com/jQuery.isEmptyObject/

This works perfectly

Just in case you would need to delete a variable, you could use SETENV from Vincent Fatica available at http://barnyard.syr.edu/~vefatica. Not exactly recent ('98) but still working on Windows 7 x64.

If you have no control over the page and wish to watch for some kind of change then the modern method is to use MutationObserver

An example of its use, watching for the src attribute to change of an iframe

new MutationObserver(function(mutations) {_x000D_
  mutations.some(function(mutation) {_x000D_
    if (mutation.type === 'attributes' && mutation.attributeName === 'src') {_x000D_
      console.log(mutation);_x000D_
      console.log('Old src: ', mutation.oldValue);_x000D_
      console.log('New src: ', mutation.target.src);_x000D_
      return true;_x000D_
    }_x000D_
_x000D_
    return false;_x000D_
  });_x000D_
}).observe(document.body, {_x000D_
  attributes: true,_x000D_
  attributeFilter: ['src'],_x000D_
  attributeOldValue: true,_x000D_
  characterData: false,_x000D_
  characterDataOldValue: false,_x000D_
  childList: false,_x000D_
  subtree: true_x000D_
});_x000D_
_x000D_
setTimeout(function() {_x000D_
  document.getElementsByTagName('iframe')[0].src = 'http://jsfiddle.net/';_x000D_
}, 3000);

<iframe src="http://www.google.com"></iframe>

Output after 3 seconds

MutationRecord {oldValue: "http://www.google.com", attributeNamespace: null, attributeName: "src", nextSibling: null, previousSibling: null…}
Old src:  http://www.google.com
New src:  http://jsfiddle.net/

Swift 3:

extension URL {
    func getQueryItemValueForKey(key: String) -> String? {
        guard let components = NSURLComponents(url: self, resolvingAgainstBaseURL: false) else {
              return nil
        }

        guard let queryItems = components.queryItems else { return nil }
     return queryItems.filter {
                 $0.name.lowercased() == key.lowercased()
                 }.first?.value
    }
}

I used it to get the image name for UIImagePickerController in func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]):

var originalFilename = ""
if let url = info[UIImagePickerControllerReferenceURL] as? URL, let imageIdentifier = url.getQueryItemValueForKey(key: "id") {
    originalFilename = imageIdentifier + ".png"
    print("file name : \(originalFilename)")
}

Avoid any? for large arrays.

• any? is O(n)
• empty? is O(1)

any? does not check the length but actually scans the whole array for truthy elements.

static VALUE
rb_ary_any_p(VALUE ary)
{
  long i, len = RARRAY_LEN(ary);
  const VALUE *ptr = RARRAY_CONST_PTR(ary);

  if (!len) return Qfalse;
  if (!rb_block_given_p()) {
    for (i = 0; i < len; ++i) if (RTEST(ptr[i])) return Qtrue;
  }
  else {
    for (i = 0; i < RARRAY_LEN(ary); ++i) {
        if (RTEST(rb_yield(RARRAY_AREF(ary, i)))) return Qtrue;
    }
  }
  return Qfalse;
}

empty? on the other hand checks the length of the array only.

static VALUE
rb_ary_empty_p(VALUE ary)
{
  if (RARRAY_LEN(ary) == 0)
    return Qtrue;
  return Qfalse;
}

The difference is relevant if you have "sparse" arrays that start with lots of nil values, like for example an array that was just created.

With node, try

var s3 = new AWS.S3( {
    endpoint: 's3-eu-central-1.amazonaws.com',
    signatureVersion: 'v4',
    region: 'eu-central-1'
} );

If you mean that you want to enable the submit after the user has typed at least one character, then you need to attach a key event that will check it for you.

Something like:

$("#fbss").keypress(function() {
    if($(this).val().length > 1) {
         // Enable submit button
    } else {
         // Disable submit button
    }
});

Try this, as it solved in my case on a Samsung mobile phone:

1. Open the "Google Play" app and press the home button to return

2. Go to Settings ? Applications ? Manage Applications

3. Select the "ALL" tab, Search for "Google Play Store" and press it to open.

4. Press "Force stop"

5. Press "Clear cache"

6. Press "Clear Data"

7. Now Open Play Store and it will work normally.

If the above steps does not help then try the following as well:

1. Go to Settings ? Applications ? Manage Applications

2. Select the "ALL" tab, Search for "Google Services Framework" and press it to open.

3. Press "Force stop"

4. Press "Clear cache"

5. Press "Clear Data"

To do with javascript you could do something like this:

<script type="Text/javascript">
var text = <?= $text_from_db; ?>
</script>

Then you can use whatever you want in your javascript to put the text var into the textbox.

If you want to find all commits where commit message contains given word, use

$ git log --grep=word

If you want to find all commits where "word" was added or removed in the file contents (to be more exact: where number of occurences of "word" changed), i.e. search the commit contents, use so called 'pickaxe' search with

$ git log -Sword

In modern git there is also

$ git log -Gword

to look for differences whose added or removed line matches "word" (also commit contents).

Note that -G by default accepts a regex, while -S accepts a string, but can be modified to accept regexes using the --pickaxe-regex.

To illustrate the difference between -S<regex> --pickaxe-regex and -G<regex>, consider a commit with the following diff in the same file:

+    return !regexec(regexp, two->ptr, 1, &regmatch, 0);
...
-    hit = !regexec(regexp, mf2.ptr, 1, &regmatch, 0);

While git log -G"regexec\(regexp" will show this commit, git log -S"regexec\(regexp" --pickaxe-regex will not (because the number of occurrences of that string did not change).

With Git 2.25.1 (Feb. 2020), the documentation is clarified around those regexes.

See commit 9299f84 (06 Feb 2020) by Martin Ågren (``).
^{(Merged by Junio C Hamano -- gitster -- in commit 0d11410, 12 Feb 2020)}

diff-options.txt: avoid "regex" overload in example

^{Reported-by: Adam Dinwoodie
Signed-off-by: Martin Ågren
Reviewed-by: Taylor Blau}

When we exemplify the difference between -G and -S (using --pickaxe-regex), we do so using an example diff and git diff invocation involving "regexec", "regexp", "regmatch", ...

The example is correct, but we can make it easier to untangle by avoiding writing "regex.*" unless it's really needed to make our point.

Use some made-up, non-regexy words instead.

The git diff documentation now includes:

To illustrate the difference between -S<regex> --pickaxe-regex and -G<regex>, consider a commit with the following diff in the same file:

+    return frotz(nitfol, two->ptr, 1, 0);
...
-    hit = frotz(nitfol, mf2.ptr, 1, 0);

While git log -G"frotz\(nitfol" will show this commit, git log -S"frotz\(nitfol" --pickaxe-regex will not (because the number of occurrences of that string did not change).

The simplest way to accomplish this is to put the input method in a while loop. Use continue when you get bad input, and break out of the loop when you're satisfied.

When Your Input Might Raise an Exception

Use try and except to detect when the user enters data that can't be parsed.

while True:
    try:
        # Note: Python 2.x users should use raw_input, the equivalent of 3.x's input
        age = int(input("Please enter your age: "))
    except ValueError:
        print("Sorry, I didn't understand that.")
        #better try again... Return to the start of the loop
        continue
    else:
        #age was successfully parsed!
        #we're ready to exit the loop.
        break
if age >= 18: 
    print("You are able to vote in the United States!")
else:
    print("You are not able to vote in the United States.")

Implementing Your Own Validation Rules

If you want to reject values that Python can successfully parse, you can add your own validation logic.

while True:
    data = input("Please enter a loud message (must be all caps): ")
    if not data.isupper():
        print("Sorry, your response was not loud enough.")
        continue
    else:
        #we're happy with the value given.
        #we're ready to exit the loop.
        break

while True:
    data = input("Pick an answer from A to D:")
    if data.lower() not in ('a', 'b', 'c', 'd'):
        print("Not an appropriate choice.")
    else:
        break

Combining Exception Handling and Custom Validation

Both of the above techniques can be combined into one loop.

while True:
    try:
        age = int(input("Please enter your age: "))
    except ValueError:
        print("Sorry, I didn't understand that.")
        continue

    if age < 0:
        print("Sorry, your response must not be negative.")
        continue
    else:
        #age was successfully parsed, and we're happy with its value.
        #we're ready to exit the loop.
        break
if age >= 18: 
    print("You are able to vote in the United States!")
else:
    print("You are not able to vote in the United States.")

Encapsulating it All in a Function

If you need to ask your user for a lot of different values, it might be useful to put this code in a function, so you don't have to retype it every time.

def get_non_negative_int(prompt):
    while True:
        try:
            value = int(input(prompt))
        except ValueError:
            print("Sorry, I didn't understand that.")
            continue

        if value < 0:
            print("Sorry, your response must not be negative.")
            continue
        else:
            break
    return value

age = get_non_negative_int("Please enter your age: ")
kids = get_non_negative_int("Please enter the number of children you have: ")
salary = get_non_negative_int("Please enter your yearly earnings, in dollars: ")

Putting It All Together

You can extend this idea to make a very generic input function:

def sanitised_input(prompt, type_=None, min_=None, max_=None, range_=None):
    if min_ is not None and max_ is not None and max_ < min_:
        raise ValueError("min_ must be less than or equal to max_.")
    while True:
        ui = input(prompt)
        if type_ is not None:
            try:
                ui = type_(ui)
            except ValueError:
                print("Input type must be {0}.".format(type_.__name__))
                continue
        if max_ is not None and ui > max_:
            print("Input must be less than or equal to {0}.".format(max_))
        elif min_ is not None and ui < min_:
            print("Input must be greater than or equal to {0}.".format(min_))
        elif range_ is not None and ui not in range_:
            if isinstance(range_, range):
                template = "Input must be between {0.start} and {0.stop}."
                print(template.format(range_))
            else:
                template = "Input must be {0}."
                if len(range_) == 1:
                    print(template.format(*range_))
                else:
                    expected = " or ".join((
                        ", ".join(str(x) for x in range_[:-1]),
                        str(range_[-1])
                    ))
                    print(template.format(expected))
        else:
            return ui

With usage such as:

age = sanitised_input("Enter your age: ", int, 1, 101)
answer = sanitised_input("Enter your answer: ", str.lower, range_=('a', 'b', 'c', 'd'))

Common Pitfalls, and Why you Should Avoid Them

The Redundant Use of Redundant input Statements

This method works but is generally considered poor style:

data = input("Please enter a loud message (must be all caps): ")
while not data.isupper():
    print("Sorry, your response was not loud enough.")
    data = input("Please enter a loud message (must be all caps): ")

It might look attractive initially because it's shorter than the while True method, but it violates the Don't Repeat Yourself principle of software development. This increases the likelihood of bugs in your system. What if you want to backport to 2.7 by changing input to raw_input, but accidentally change only the first input above? It's a SyntaxError just waiting to happen.

Recursion Will Blow Your Stack

If you've just learned about recursion, you might be tempted to use it in get_non_negative_int so you can dispose of the while loop.

def get_non_negative_int(prompt):
    try:
        value = int(input(prompt))
    except ValueError:
        print("Sorry, I didn't understand that.")
        return get_non_negative_int(prompt)

    if value < 0:
        print("Sorry, your response must not be negative.")
        return get_non_negative_int(prompt)
    else:
        return value

This appears to work fine most of the time, but if the user enters invalid data enough times, the script will terminate with a RuntimeError: maximum recursion depth exceeded. You may think "no fool would make 1000 mistakes in a row", but you're underestimating the ingenuity of fools!

If you are interested in a pure Javascript solution, here is the one that I copy from Brett:

function detectflash(){
    if (navigator.plugins != null && navigator.plugins.length > 0){
        return navigator.plugins["Shockwave Flash"] && true;
    }
    if(~navigator.userAgent.toLowerCase().indexOf("webtv")){
        return true;
    }
    if(~navigator.appVersion.indexOf("MSIE") && !~navigator.userAgent.indexOf("Opera")){
        try{
            return new ActiveXObject("ShockwaveFlash.ShockwaveFlash") && true;
        } catch(e){}
    }
    return false;
}

If one or both of your dates are in the future, then I'm afraid you're SOL if you want to-the-second accuracy. UTC time has leap seconds that aren't known until about 6 months before they happen, so any dates further out than that can be inaccurate by some number of seconds (and in practice, since people don't update their machines that often, you may find that any time in the future is off by some number of seconds).

This gives a good explanation of the theory of designing date/time libraries and why this is so: http://www.boost.org/doc/libs/1_41_0/doc/html/date_time/details.html#date_time.tradeoffs

also had same problem once,

if you are unable to solve the problem you can run the following command on command line
chrome.exe --user-data-dir="C://Chrome dev session" --disable-web-security

Note: you have to navigate to the installation path of your chrome.
For example:cd C:\Program Files\Google\Chrome\Application

A developer session chrome browser will be opened, you can now launch your app on the new chrome browse.
I hope this should be helpful

It's been quite sometime since I asked this question. Now I understand it more clearly, I'm going to put a more complete answer to help others.

In Web API, it's very simple to remember how parameter binding is happening.

• if you POST simple types, Web API tries to bind it from the URL

• if you POST complex type, Web API tries to bind it from the body of the request (this uses a media-type formatter).

• If you want to bind a complex type from the URL, you'll use [FromUri] in your action parameter. The limitation of this is down to how long your data going to be and if it exceeds the url character limit.

  public IHttpActionResult Put([FromUri] ViewModel data) { ... }

• If you want to bind a simple type from the request body, you'll use [FromBody] in your action parameter.

  public IHttpActionResult Put([FromBody] string name) { ... }

as a side note, say you are making a PUT request (just a string) to update something. If you decide not to append it to the URL and pass as a complex type with just one property in the model, then the data parameter in jQuery ajax will look something like below. The object you pass to data parameter has only one property with empty property name.

var myName = 'ABC';
$.ajax({url:.., data: {'': myName}});

and your web api action will look something like below.

public IHttpActionResult Put([FromBody] string name){ ... }

This asp.net page explains it all. http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api

It's new in the Bootstrap 3.0.1 release, so make sure you have the latest (10/29)...

Demo: http://bootply.com/91632

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
<div class="row">_x000D_
    <div class="center-block" style="width:200px;background-color:#ccc;">...</div>_x000D_
</div>

Here is simple code. You must set an id for your input. Here call it 'myInput':

var myform = document.getElementById('myform');
myform.onsubmit = function(){
    document.getElementById('myInput').value = '1';
    myform.submit();
};

Put the modal and javascript into the partial view. Then call the partial view in your page. This will handle form submission too.

Partial View

<div id="confirmDialog" class="modal fade" data-backdrop="false">
 <div class="modal-dialog" data-backdrop="false">
    <div class="modal-content">
        <div class="modal-header">
            <h4 class="modal-title">Missing Service Order</h4>
        </div>
        <div class="modal-body">
            <p>You have not entered a Service Order. Do you want to continue?</p>
        </div>
        <div class="modal-footer">
            <input id="btnSubmit" type="submit" class="btn btn-primary" 
              value="Submit" href="javascript:" 
               onClick="document.getElementById('Coordinate').submit()" />
            <button type="button" class="btn btn-default" data- 
                                               dismiss="modal">Cancel</button>
        </div>
    </div>
  </div>
</div>

Javascript

  <script type="text/javascript" language="javascript">
$(document).ready(function () {
    $("#Coordinate").on('submit',
        function (e) {
            if ($("#ServiceOrder").val() == '') {
                e.preventDefault();
                $('#confirmDialog').modal('show');
               }
            });
    });
</script>

Then just call your partial inside the form of your page.

Create.cshtml

 @using (Html.BeginForm("Edit","Home",FormMethod.Post, new {id ="Coordinate"}))
 {
     //Form Code

     @Html.Partial("ConfirmDialog") 
 }

You can use numpy.logical_not to invert the boolean array returned by isin:

In [63]: s = pd.Series(np.arange(10.0))

In [64]: x = range(4, 8)

In [65]: mask = np.logical_not(s.isin(x))

In [66]: s[mask]
Out[66]: 
0    0
1    1
2    2
3    3
8    8
9    9

As given in the comment by Wes McKinney you can also use

s[~s.isin(x)]

In Windows, if you have the shortcut in your taskbar, right-click the "Anaconda Prompt" icon, you'll see:

• Anaconda Prompt
• Unpin from taskbar (if pinned)
• Close window

Right-click on "Anaconda Prompt" again.

Click "Properties"

Add the path you want your anaconda prompt to open up into in the "Start In:" section.

Note - you can also do this by searching for "Anaconda Prompt" in the Start Menu. The directions above are specifically for the shortcut.

Try this:

function removeClassDelayed(jqObj, c, to) {    
    setTimeout(function() { jqObj.removeClass(c); }, to);
}
removeClassDelayed($("#div"), "error", 1000);

This is called type assertion in TypeScript, and since TypeScript 1.6, there are two ways to express this:

// Original syntax
var markerSymbolInfo = <MarkerSymbolInfo> symbolInfo;

// Newer additional syntax
var markerSymbolInfo = symbolInfo as MarkerSymbolInfo;

Both alternatives are functionally identical. The reason for introducing the as-syntax is that the original syntax conflicted with JSX, see the design discussion here.

If you are in a position to choose, just use the syntax that you feel more comfortable with. I personally prefer the as-syntax as it feels more fluent to read and write.

You can simply pass your dataframe into the following function:

def sum_frame_by_column(frame, new_col_name, list_of_cols_to_sum):
    frame[new_col_name] = frame[list_of_cols_to_sum].astype(float).sum(axis=1)
    return(frame)

Example:

I have a dataframe (awards_frame) as follows:

...and I want to create a new column that shows the sum of awards for each row:

Usage:

I simply pass my awards_frame into the function, also specifying the name of the new column, and a list of column names that are to be summed:

sum_frame_by_column(awards_frame, 'award_sum', ['award_1','award_2','award_3'])

Result:

Have checked that many of the answered are with static array, what if suppose I have special character in the string and want a solution with dynamic concept. There can be many other possible solutions, it is one of them.

here is the solutions with the Linked List.

This may not be what you want to hear, but display: table-cell does not respect width and will be collapsed based on the width of the entire table. You can get around this easily just by having a display: block element inside of the table cell itself whose width you specify, e.g

<td><div style="width: 300px;">wide</div></td>

This shouldn't make much of a difference if the <table> itself is position: fixed or absolute because the position of the cells are all static relative to the table.

http://jsfiddle.net/ExplosionPIlls/Mkq8L/4/

EDIT: I can't take credit, but as the comments say you can just use min-width instead of width on the table cell instead.

Struct values encode as JSON objects. Each exported struct field becomes a member of the object unless:

• the field's tag is "-", or
• the field is empty and its tag specifies the "omitempty" option.

The empty values are false, 0, any nil pointer or interface value, and any array, slice, map, or string of length zero. The object's default key string is the struct field name but can be specified in the struct field's tag value. The "json" key in the struct field's tag value is the key name, followed by an optional comma and options.

Only static functions are called with class name.

classname::Staicfunction();

Non static functions have to be called using objects.

classname obj;
obj.Somefunction();

This is exactly what your error means. Since your function is non static you have to use a object reference to invoke it.

I was having troubles understanding an applying the accepted answer. I needed a little more context. Now that I have figured it out, here is a full example:

MainActivity.java

public class MainActivity extends AppCompatActivity {

    Button myButton;
    View myView;
    boolean isUp;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        myView = findViewById(R.id.my_view);
        myButton = findViewById(R.id.my_button);

        // initialize as invisible (could also do in xml)
        myView.setVisibility(View.INVISIBLE);
        myButton.setText("Slide up");
        isUp = false;
    }

    // slide the view from below itself to the current position
    public void slideUp(View view){
        view.setVisibility(View.VISIBLE);
        TranslateAnimation animate = new TranslateAnimation(
                0,                 // fromXDelta
                0,                 // toXDelta
                view.getHeight(),  // fromYDelta
                0);                // toYDelta
        animate.setDuration(500);
        animate.setFillAfter(true);
        view.startAnimation(animate);
    }

    // slide the view from its current position to below itself
    public void slideDown(View view){
        TranslateAnimation animate = new TranslateAnimation(
                0,                 // fromXDelta
                0,                 // toXDelta
                0,                 // fromYDelta
                view.getHeight()); // toYDelta
        animate.setDuration(500);
        animate.setFillAfter(true);
        view.startAnimation(animate);
    }

    public void onSlideViewButtonClick(View view) {

            myButton.setText("Slide up");
        } else {
            slideUp(myView);

Notes

• Thanks to this article for pointing me in the right direction. It was more helpful than the other answers on this page.
• If you want to start with the view on screen, then don't initialize it as INVISIBLE.
• Since we are animating it completely off screen, there is no need to set it back to INVISIBLE. If you are not animating completely off screen, though, then you can add an alpha animation and set the visibility with an AnimatorListenerAdapter.
• Property Animation docs

All DDL statements in Oracle PL/SQL should use Execute Immediate before the statement. Hence you should use:

execute immediate 'truncate table schema.tablename';

A JSON document basically consists of lists and dictionaries. There is no obvious way to map such a datastructure on a two-dimensional table.

Please note the android:layout_alignParentEnd and android:textAlignment settings of the second TextView.

Here you go: ES5

var test = 'Hello World';
if( test.indexOf('World') >= 0){
  // Found world
}

With ES6 best way would be to use includes function to test if the string contains the looking work.

const test = 'Hello World';
if (test.includes('World')) { 
  // Found world
}

Every odd number when divided by two leaves remainder as 1 and every even number when divided by zero leaves a zero as remainder. Hence we can use this code

  function checker(number)  {
   return number%2==0?even:odd;
   }

You need to use the jQuery AJAX or XMLHttpRequest() for post the data to the server. After data posting you can redirect your page to another page by window.location.href.

Example:

 var xhttp = new XMLHttpRequest();
  xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
      window.location.href = 'https://website.com/my-account';
    }
  };
  xhttp.open("POST", "demo_post.asp", true);
  xhttp.send();

Official Documentation is here:

To build a debug APK, open a command line and navigate to the root of your project directory. To initiate a debug build, invoke the assembleDebug task:

gradlew assembleDebug

This creates an APK named module_name-debug.apk in project_name/module_name/build/outputs/apk/.

sleep(1.0/24.0)

As to your follow up question if that's the best way: No, you could get not-so-smooth framerates because the rendering of each frame might not take the same amount of time.

You could try one of these solutions:

• Use a timer which fires 24 times a second with the drawing code.
• Create as many frames as possible, create the motion based on the time passed, not per frame.

this will unhide all files and folders on your computer

attrib -r -s -h /S /D

Try webfs, it's tiny and doesn't depend on having a platform like node.js or python installed.

If you are using postgres use text wherever you can, unless you have a size constraint since there is no performance penalty for text vs varchar

There is no performance difference among these three types, apart from increased storage space when using the blank-padded type, and a few extra CPU cycles to check the length when storing into a length-constrained column. While character(n) has performance advantages in some other database systems, there is no such advantage in PostgreSQL; in fact character(n) is usually the slowest of the three because of its additional storage costs. In most situations text or character varying should be used instead

Also, you are probably inside the .git subfolder, move up one folder to your project root.

My guess is it's not in your path.
in bash, try:
echo $PATH
and
sudo which nginx
And see if the folder containing nginx is also in your $PATH variable.
If not, either add the folder to your path environment variable, or create an alias (and put it in your .bashrc) ooor your could create a link i guess.
or sudo nginx -v if you just want that...

I use Node.js at work, and find it to be very powerful. Forced to choose one word to describe Node.js, I'd say "interesting" (which is not a purely positive adjective). The community is vibrant and growing. JavaScript, despite its oddities can be a great language to code in. And you will daily rethink your own understanding of "best practice" and the patterns of well-structured code. There's an enormous energy of ideas flowing into Node.js right now, and working in it exposes you to all this thinking - great mental weightlifting.

Node.js in production is definitely possible, but far from the "turn-key" deployment seemingly promised by the documentation. With Node.js v0.6.x, "cluster" has been integrated into the platform, providing one of the essential building blocks, but my "production.js" script is still ~150 lines of logic to handle stuff like creating the log directory, recycling dead workers, etc. For a "serious" production service, you also need to be prepared to throttle incoming connections and do all the stuff that Apache does for PHP. To be fair, Ruby on Rails has this exact problem. It is solved via two complementary mechanisms: 1) Putting Ruby on Rails/Node.js behind a dedicated webserver (written in C and tested to hell and back) like Nginx (or Apache / Lighttd). The webserver can efficiently serve static content, access logging, rewrite URLs, terminate SSL, enforce access rules, and manage multiple sub-services. For requests that hit the actual node service, the webserver proxies the request through. 2) Using a framework like Unicorn that will manage the worker processes, recycle them periodically, etc. I've yet to find a Node.js serving framework that seems fully baked; it may exist, but I haven't found it yet and still use ~150 lines in my hand-rolled "production.js".

Reading frameworks like Express makes it seem like the standard practice is to just serve everything through one jack-of-all-trades Node.js service ... "app.use(express.static(__dirname + '/public'))". For lower-load services and development, that's probably fine. But as soon as you try to put big time load on your service and have it run 24/7, you'll quickly discover the motivations that push big sites to have well baked, hardened C-code like Nginx fronting their site and handling all of the static content requests (...until you set up a CDN, like Amazon CloudFront)). For a somewhat humorous and unabashedly negative take on this, see this guy.

Node.js is also finding more and more non-service uses. Even if you are using something else to serve web content, you might still use Node.js as a build tool, using npm modules to organize your code, Browserify to stitch it into a single asset, and uglify-js to minify it for deployment. For dealing with the web, JavaScript is a perfect impedance match and frequently that makes it the easiest route of attack. For example, if you want to grovel through a bunch of JSON response payloads, you should use my underscore-CLI module, the utility-belt of structured data.

Pros / Cons:

• Pro: For a server guy, writing JavaScript on the backend has been a "gateway drug" to learning modern UI patterns. I no longer dread writing client code.
• Pro: Tends to encourage proper error checking (err is returned by virtually all callbacks, nagging the programmer to handle it; also, async.js and other libraries handle the "fail if any of these subtasks fails" paradigm much better than typical synchronous code)
• Pro: Some interesting and normally hard tasks become trivial - like getting status on tasks in flight, communicating between workers, or sharing cache state
• Pro: Huge community and tons of great libraries based on a solid package manager (npm)
• Con: JavaScript has no standard library. You get so used to importing functionality that it feels weird when you use JSON.parse or some other build in method that doesn't require adding an npm module. This means that there are five versions of everything. Even the modules included in the Node.js "core" have five more variants should you be unhappy with the default implementation. This leads to rapid evolution, but also some level of confusion.

Versus a simple one-process-per-request model (LAMP):

• Pro: Scalable to thousands of active connections. Very fast and very efficient. For a web fleet, this could mean a 10X reduction in the number of boxes required versus PHP or Ruby
• Pro: Writing parallel patterns is easy. Imagine that you need to fetch three (or N) blobs from Memcached. Do this in PHP ... did you just write code the fetches the first blob, then the second, then the third? Wow, that's slow. There's a special PECL module to fix that specific problem for Memcached, but what if you want to fetch some Memcached data in parallel with your database query? In Node.js, because the paradigm is asynchronous, having a web request do multiple things in parallel is very natural.
• Con: Asynchronous code is fundamentally more complex than synchronous code, and the up-front learning curve can be hard for developers without a solid understanding of what concurrent execution actually means. Still, it's vastly less difficult than writing any kind of multithreaded code with locking.
• Con: If a compute-intensive request runs for, for example, 100 ms, it will stall processing of other requests that are being handled in the same Node.js process ... AKA, cooperative-multitasking. This can be mitigated with the Web Workers pattern (spinning off a subprocess to deal with the expensive task). Alternatively, you could use a large number of Node.js workers and only let each one handle a single request concurrently (still fairly efficient because there is no process recycle).
• Con: Running a production system is MUCH more complicated than a CGI model like Apache + PHP, Perl, Ruby, etc. Unhandled exceptions will bring down the entire process, necessitating logic to restart failed workers (see cluster). Modules with buggy native code can hard-crash the process. Whenever a worker dies, any requests it was handling are dropped, so one buggy API can easily degrade service for other cohosted APIs.

Versus writing a "real" service in Java / C# / C (C? really?)

• Pro: Doing asynchronous in Node.js is easier than doing thread-safety anywhere else and arguably provides greater benefit. Node.js is by far the least painful asynchronous paradigm I've ever worked in. With good libraries, it is only slightly harder than writing synchronous code.
• Pro: No multithreading / locking bugs. True, you invest up front in writing more verbose code that expresses a proper asynchronous workflow with no blocking operations. And you need to write some tests and get the thing to work (it is a scripting language and fat fingering variable names is only caught at unit-test time). BUT, once you get it to work, the surface area for heisenbugs -- strange problems that only manifest once in a million runs -- that surface area is just much much lower. The taxes writing Node.js code are heavily front-loaded into the coding phase. Then you tend to end up with stable code.
• Pro: JavaScript is much more lightweight for expressing functionality. It's hard to prove this with words, but JSON, dynamic typing, lambda notation, prototypal inheritance, lightweight modules, whatever ... it just tends to take less code to express the same ideas.
• Con: Maybe you really, really like coding services in Java?

For another perspective on JavaScript and Node.js, check out From Java to Node.js, a blog post on a Java developer's impressions and experiences learning Node.js.

Modules When considering node, keep in mind that your choice of JavaScript libraries will DEFINE your experience. Most people use at least two, an asynchronous pattern helper (Step, Futures, Async), and a JavaScript sugar module (Underscore.js).

Helper / JavaScript Sugar:

• Underscore.js - use this. Just do it. It makes your code nice and readable with stuff like _.isString(), and _.isArray(). I'm not really sure how you could write safe code otherwise. Also, for enhanced command-line-fu, check out my own Underscore-CLI.

Asynchronous Pattern Modules:

• Step - a very elegant way to express combinations of serial and parallel actions. My personal reccomendation. See my post on what Step code looks like.
• Futures - much more flexible (is that really a good thing?) way to express ordering through requirements. Can express things like "start a, b, c in parallel. When A, and B finish, start AB. When A, and C finish, start AC." Such flexibility requires more care to avoid bugs in your workflow (like never calling the callback, or calling it multiple times). See Raynos's post on using futures (this is the post that made me "get" futures).
• Async - more traditional library with one method for each pattern. I started with this before my religious conversion to step and subsequent realization that all patterns in Async could be expressed in Step with a single more readable paradigm.
• TameJS - Written by OKCupid, it's a precompiler that adds a new language primative "await" for elegantly writing serial and parallel workflows. The pattern looks amazing, but it does require pre-compilation. I'm still making up my mind on this one.
• StreamlineJS - competitor to TameJS. I'm leaning toward Tame, but you can make up your own mind.

Or to read all about the asynchronous libraries, see this panel-interview with the authors.

Web Framework:

• Express Great Ruby on Rails-esk framework for organizing web sites. It uses JADE as a XML/HTML templating engine, which makes building HTML far less painful, almost elegant even.
• jQuery While not technically a node module, jQuery is quickly becoming a de-facto standard for client-side user interface. jQuery provides CSS-like selectors to 'query' for sets of DOM elements that can then be operated on (set handlers, properties, styles, etc). Along the same vein, Twitter's Bootstrap CSS framework, Backbone.js for an MVC pattern, and Browserify.js to stitch all your JavaScript files into a single file. These modules are all becoming de-facto standards so you should at least check them out if you haven't heard of them.

Testing:

• JSHint - Must use; I didn't use this at first which now seems incomprehensible. JSLint adds back a bunch of the basic verifications you get with a compiled language like Java. Mismatched parenthesis, undeclared variables, typeos of many shapes and sizes. You can also turn on various forms of what I call "anal mode" where you verify style of whitespace and whatnot, which is OK if that's your cup of tea -- but the real value comes from getting instant feedback on the exact line number where you forgot a closing ")" ... without having to run your code and hit the offending line. "JSHint" is a more-configurable variant of Douglas Crockford's JSLint.
• Mocha competitor to Vows which I'm starting to prefer. Both frameworks handle the basics well enough, but complex patterns tend to be easier to express in Mocha.
• Vows Vows is really quite elegant. And it prints out a lovely report (--spec) showing you which test cases passed / failed. Spend 30 minutes learning it, and you can create basic tests for your modules with minimal effort.
• Zombie - Headless testing for HTML and JavaScript using JSDom as a virtual "browser". Very powerful stuff. Combine it with Replay to get lightning fast deterministic tests of in-browser code.
• A comment on how to "think about" testing:
  • Testing is non-optional. With a dynamic language like JavaScript, there are very few static checks. For example, passing two parameters to a method that expects 4 won't break until the code is executed. Pretty low bar for creating bugs in JavaScript. Basic tests are essential to making up the verification gap with compiled languages.
  • Forget validation, just make your code execute. For every method, my first validation case is "nothing breaks", and that's the case that fires most often. Proving that your code runs without throwing catches 80% of the bugs and will do so much to improve your code confidence that you'll find yourself going back and adding the nuanced validation cases you skipped.
  • Start small and break the inertial barrier. We are all lazy, and pressed for time, and it's easy to see testing as "extra work". So start small. Write test case 0 - load your module and report success. If you force yourself to do just this much, then the inertial barrier to testing is broken. That's <30 min to do it your first time, including reading the documentation. Now write test case 1 - call one of your methods and verify "nothing breaks", that is, that you don't get an error back. Test case 1 should take you less than one minute. With the inertia gone, it becomes easy to incrementally expand your test coverage.
  • Now evolve your tests with your code. Don't get intimidated by what the "correct" end-to-end test would look like with mock servers and all that. Code starts simple and evolves to handle new cases; tests should too. As you add new cases and new complexity to your code, add test cases to exercise the new code. As you find bugs, add verifications and / or new cases to cover the flawed code. When you are debugging and lose confidence in a piece of code, go back and add tests to prove that it is doing what you think it is. Capture strings of example data (from other services you call, websites you scrape, whatever) and feed them to your parsing code. A few cases here, improved validation there, and you will end up with highly reliable code.

Also, check out the official list of recommended Node.js modules. However, GitHub's Node Modules Wiki is much more complete and a good resource.

To understand Node, it's helpful to consider a few of the key design choices:

Node.js is EVENT BASED and ASYNCHRONOUS / NON-BLOCKING. Events, like an incoming HTTP connection will fire off a JavaScript function that does a little bit of work and kicks off other asynchronous tasks like connecting to a database or pulling content from another server. Once these tasks have been kicked off, the event function finishes and Node.js goes back to sleep. As soon as something else happens, like the database connection being established or the external server responding with content, the callback functions fire, and more JavaScript code executes, potentially kicking off even more asynchronous tasks (like a database query). In this way, Node.js will happily interleave activities for multiple parallel workflows, running whatever activities are unblocked at any point in time. This is why Node.js does such a great job managing thousands of simultaneous connections.

Why not just use one process/thread per connection like everyone else? In Node.js, a new connection is just a very small heap allocation. Spinning up a new process takes significantly more memory, a megabyte on some platforms. But the real cost is the overhead associated with context-switching. When you have 10^6 kernel threads, the kernel has to do a lot of work figuring out who should execute next. A bunch of work has gone into building an O(1) scheduler for Linux, but in the end, it's just way way more efficient to have a single event-driven process than 10^6 processes competing for CPU time. Also, under overload conditions, the multi-process model behaves very poorly, starving critical administration and management services, especially SSHD (meaning you can't even log into the box to figure out how screwed it really is).

Node.js is SINGLE THREADED and LOCK FREE. Node.js, as a very deliberate design choice only has a single thread per process. Because of this, it's fundamentally impossible for multiple threads to access data simultaneously. Thus, no locks are needed. Threads are hard. Really really hard. If you don't believe that, you haven't done enough threaded programming. Getting locking right is hard and results in bugs that are really hard to track down. Eliminating locks and multi-threading makes one of the nastiest classes of bugs just go away. This might be the single biggest advantage of node.

But how do I take advantage of my 16 core box?

Two ways:

1. For big heavy compute tasks like image encoding, Node.js can fire up child processes or send messages to additional worker processes. In this design, you'd have one thread managing the flow of events and N processes doing heavy compute tasks and chewing up the other 15 CPUs.
2. For scaling throughput on a webservice, you should run multiple Node.js servers on one box, one per core, using cluster (With Node.js v0.6.x, the official "cluster" module linked here replaces the learnboost version which has a different API). These local Node.js servers can then compete on a socket to accept new connections, balancing load across them. Once a connection is accepted, it becomes tightly bound to a single one of these shared processes. In theory, this sounds bad, but in practice it works quite well and allows you to avoid the headache of writing thread-safe code. Also, this means that Node.js gets excellent CPU cache affinity, more effectively using memory bandwidth.

Node.js lets you do some really powerful things without breaking a sweat. Suppose you have a Node.js program that does a variety of tasks, listens on a TCP port for commands, encodes some images, whatever. With five lines of code, you can add in an HTTP based web management portal that shows the current status of active tasks. This is EASY to do:

var http = require('http');
http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end(myJavascriptObject.getSomeStatusInfo());
}).listen(1337, "127.0.0.1");

Now you can hit a URL and check the status of your running process. Add a few buttons, and you have a "management portal". If you have a running Perl / Python / Ruby script, just "throwing in a management portal" isn't exactly simple.

But isn't JavaScript slow / bad / evil / spawn-of-the-devil? JavaScript has some weird oddities, but with "the good parts" there's a very powerful language there, and in any case, JavaScript is THE language on the client (browser). JavaScript is here to stay; other languages are targeting it as an IL, and world class talent is competing to produce the most advanced JavaScript engines. Because of JavaScript's role in the browser, an enormous amount of engineering effort is being thrown at making JavaScript blazing fast. V8 is the latest and greatest javascript engine, at least for this month. It blows away the other scripting languages in both efficiency AND stability (looking at you, Ruby). And it's only going to get better with huge teams working on the problem at Microsoft, Google, and Mozilla, competing to build the best JavaScript engine (It's no longer a JavaScript "interpreter" as all the modern engines do tons of JIT compiling under the hood with interpretation only as a fallback for execute-once code). Yeah, we all wish we could fix a few of the odder JavaScript language choices, but it's really not that bad. And the language is so darn flexible that you really aren't coding JavaScript, you are coding Step or jQuery -- more than any other language, in JavaScript, the libraries define the experience. To build web applications, you pretty much have to know JavaScript anyway, so coding with it on the server has a sort of skill-set synergy. It has made me not dread writing client code.

Besides, if you REALLY hate JavaScript, you can use syntactic sugar like CoffeeScript. Or anything else that creates JavaScript code, like Google Web Toolkit (GWT).

Speaking of JavaScript, what's a "closure"? - Pretty much a fancy way of saying that you retain lexically scoped variables across call chains. ;) Like this:

var myData = "foo";
database.connect( 'user:pass', function myCallback( result ) {
    database.query("SELECT * from Foo where id = " + myData);
} );
// Note that doSomethingElse() executes _BEFORE_ "database.query" which is inside a callback
doSomethingElse();

See how you can just use "myData" without doing anything awkward like stashing it into an object? And unlike in Java, the "myData" variable doesn't have to be read-only. This powerful language feature makes asynchronous-programming much less verbose and less painful.

Writing asynchronous code is always going to be more complex than writing a simple single-threaded script, but with Node.js, it's not that much harder and you get a lot of benefits in addition to the efficiency and scalability to thousands of concurrent connections...

The answer to this question depends on which platform you are using.
But irrespective of platform, you can reliably assume the following types:

 [8-bit] signed char: -127 to 127
 [8-bit] unsigned char: 0 to 255
 [16-bit]signed short: -32767 to 32767
 [16-bit]unsigned short: 0 to 65535
 [32-bit]signed long: -2147483647 to 2147483647
 [32-bit]unsigned long: 0 to 4294967295
 [64-bit]signed long long: -9223372036854775807 to 9223372036854775807
 [64-bit]unsigned long long: 0 to 18446744073709551615

I included the JS and CSS file and was wondering why it is not working, what made it work was when I added the following in <head>:

<script>
jQuery(function ($) {
    $("a").tooltip()
});
</script>

Absolutely - you basically want:

var results = from p in persons
              group p.car by p.PersonId into g
              select new { PersonId = g.Key, Cars = g.ToList() };

Or as a non-query expression:

var results = persons.GroupBy(
    p => p.PersonId, 
    p => p.car,
    (key, g) => new { PersonId = key, Cars = g.ToList() });

Basically the contents of the group (when viewed as an IEnumerable<T>) is a sequence of whatever values were in the projection (p.car in this case) present for the given key.

For more on how GroupBy works, see my Edulinq post on the topic.

(I've renamed PersonID to PersonId in the above, to follow .NET naming conventions.)

Alternatively, you could use a Lookup:

var carsByPersonId = persons.ToLookup(p => p.PersonId, p => p.car);

You can then get the cars for each person very easily:

// This will be an empty sequence for any personId not in the lookup
var carsForPerson = carsByPersonId[personId];

I use hebrew(RTL language) in strings.xml. I have manually searched the string.xml for this char: ' than I added the escape char \ infront of it (now it looks like \' ) and still got the same error!

I searched again for the char ' and I replaced the char ' with \'(eng writing) , since it shows a right to left it looks like that '\ in the strings.xml !!

Problem solved.

Just set the expiration date to one hour ago, if you want to "remove" the cookie, like this:

setcookie ("TestCookie", "", time() - 3600);

or

setcookie ("TestCookie", "", time() - 3600, "/~rasmus/", "example.com", 1);

Source: http://www.php.net/manual/en/function.setcookie.php

You should use the filter_input() function for all globals which a visitor can enter/manipulate, like this:

$visitors_ip = filter_input(INPUT_COOKIE, 'id');

You can read more about it here: http://www.php.net/manual/en/function.filter-input.php and here: http://www.w3schools.com/php/func_filter_input.asp
