Check these steps.

1. go to Sql Server Configuration management->SQL Server network config->protocols for 'servername' and check TCP/IP is enabled.
2. Open SSMS in run, and check you are able to login to server using specfied username/password and/or using windows authentication.
3. repeat step 1 for SQL native client config also

I created this simple example from different search results on the internet.

public static ServiceHost CreateServiceHost(Type serviceInterface, Type implementation)
{
  //Create base address
  string baseAddress = "net.pipe://localhost/MyService";

  ServiceHost serviceHost = new ServiceHost(implementation, new Uri(baseAddress));

  //Net named pipe
  NetNamedPipeBinding binding = new NetNamedPipeBinding { MaxReceivedMessageSize = 2147483647 };
  serviceHost.AddServiceEndpoint(serviceInterface, binding, baseAddress);

  //MEX - Meta data exchange
  ServiceMetadataBehavior behavior = new ServiceMetadataBehavior();
  serviceHost.Description.Behaviors.Add(behavior);
  serviceHost.AddServiceEndpoint(typeof(IMetadataExchange), MetadataExchangeBindings.CreateMexNamedPipeBinding(), baseAddress + "/mex/");

  return serviceHost;
}

Using the above URI I can add a reference in my client to the web service.

Pipes are a way of streaming data between applications. Under Linux I use this all the time to stream the output of one process into another. This is anonymous because the destination app has no idea where that input-stream comes from. It doesn't need to.

A named pipe is just a way of actively hooking onto an existing pipe and hoovering-up its data. It's for situations where the provider doesn't know what clients will be eating the data.

Named pipes and sockets are not functionally equivalent; sockets provide more features (they are bidirectional, for a start).

We cannot tell you which will perform better, but I strongly suspect it doesn't matter.

Unix domain sockets will do pretty much what tcp sockets will, but only on the local machine and with (perhaps a bit) lower overhead.

If a Unix socket isn't fast enough and you're transferring a lot of data, consider using shared memory between your client and server (which is a LOT more complicated to set up).

Unix and NT both have "Named pipes" but they are totally different in feature set.

Within Java 7 you can define multiple catch clauses like:

catch (IllegalArgumentException | SecurityException e)
{
    ...
}

Just remember that modifying the padding or margins on any bootstrap grid elements is likely to create overflowing elements at some point at lower screen-widths.

If that happens just remember to use CSS media queries and only include the margins at screen-widths that can handle it.

In keeping with the mobile-first approach of the framework you are working within (bootstrap) it is better to add the padding at widths which can handle it, rather than excluding it at widths which can't.

@media (min-width: 992px){
    .navbar li {
        margin-left : 1em;
        margin-right : 1em;
    }
}

If you have changed your assembly version or copied a different version of the managed library stated in the error you may also have previously compiled files referencing the wrong version. A 'Rebuild All' (or deleting you 'bin and 'obj' folders as mentioned in an earlier comment) should fix this case.

One hot encoding with pandas is very easy:

def one_hot(df, cols):
    """
    @param df pandas DataFrame
    @param cols a list of columns to encode 
    @return a DataFrame with one-hot encoding
    """
    for each in cols:
        dummies = pd.get_dummies(df[each], prefix=each, drop_first=False)
        df = pd.concat([df, dummies], axis=1)
    return df

EDIT:

Another way to one_hot using sklearn's LabelBinarizer :

from sklearn.preprocessing import LabelBinarizer 
label_binarizer = LabelBinarizer()
label_binarizer.fit(all_your_labels_list) # need to be global or remembered to use it later

def one_hot_encode(x):
    """
    One hot encode a list of sample labels. Return a one-hot encoded vector for each label.
    : x: List of sample Labels
    : return: Numpy array of one-hot encoded labels
    """
    return label_binarizer.transform(x)

The point for diamond operator is simply to reduce typing of code when declaring generic types. It doesn't have any effect on runtime whatsoever.

The only difference if you specify in Java 5 and 6,

List<String> list = new ArrayList();

is that you have to specify @SuppressWarnings("unchecked") to the list (otherwise you will get an unchecked cast warning). My understanding is that diamond operator is trying to make development easier. It's got nothing to do on runtime execution of generics at all.

Interesting info about MSCorlib:

• The .NET 2.0 assembly will reference and use the 2.0 mscorlib.The .NET 1.1 assembly will reference the 1.1 mscorlib but will use the 2.0 mscorlib at runtime (due to hard-coded version redirects in theruntime itself)
• In GAC there is only one version of mscorlib, you dont find 1.1 version on GAC even if you have 1.1 framework installed on your machine. It would be good if somebody can explain why MSCorlib 2.0 alone is in GAC whereas 1.x version live inside framework folder
• Is it possible to force a different runtime to be loaded by the application by making a config setting in your app / web.config? you won’t be able to choose the CLR version by settings in the ConfigurationFile – at that point, a CLR will already be running, and there can only be one per process. Immediately after the CLR is chosen the MSCorlib appropriate for that CLR is loaded.

what's to stop other languages from being able to compile down to binary that runs every bit as fast as C?

Nothing. Modern languages like Java or .NET langs are oriented more on programmer productivity rather than performance. Hardware is cheap now days. Also compilation to intermediate representation gives a lot of bonuses such as security, portability etc. .NET CLR can take advantage of different hardware - for example you don't need to manually optimize/recompile program to use SSE instructions set.

I ran into a similar issue today - my ruby version didn't match my rvm installs.

Also, rvm current failed.

> rvm current
Warning! PATH is not properly set up, '/Users/randallreed/.rvm/gems/ruby-2.2.1/bin' is not at first place...

The error message recommended this useful command, which resolved the issue for me:

You might want to use the detach program. You use it like nohup but it doesn't produce an output log unless you tell it to. Here is the man page:

NAME
       detach - run a command after detaching from the terminal

SYNOPSIS
       detach [options] [--] command [args]

       Forks  a  new process, detaches is from the terminal, and executes com-
       mand with the specified arguments.

OPTIONS
       detach recognizes a couple of options, which are discussed below.   The
       special  option -- is used to signal that the rest of the arguments are
       the command and args to be passed to it.

       -e file
              Connect file to the standard error of the command.

       -f     Run in the foreground (do not fork).

       -i file
              Connect file to the standard input of the command.

       -o file
              Connect file to the standard output of the command.

       -p file
              Write the pid of the detached process to file.

EXAMPLE
       detach xterm

       Start an xterm that will not be closed when the current shell exits.

AUTHOR
       detach was written by Robbert Haarman.  See  http://inglorion.net/  for
       contact information.

Note I have no affiliation with the author of the program. I'm only a satisfied user of the program.

So, whatever adding splice method to a String prototype cant work transparent to spec...

Let's do some one extend it:

String.prototype.splice = function(...a){
    for(var r = '', p = 0, i = 1; i < a.length; i+=3)
        r+= this.slice(p, p=a[i-1]) + (a[i+1]||'') + this.slice(p+a[i], p=a[i+2]||this.length);
    return r;
}

• Every 3 args group "inserting" in splice style.
• Special if there is more then one 3 args group, the end off each cut will be the start of next.
  • '0123456789'.splice(4,1,'fourth',8,1,'eighth'); //return '0123fourth567eighth9'
• You can drop or zeroing the last arg in each group (that treated as "nothing to insert")
  • '0123456789'.splice(-4,2); //return '0123459'
• You can drop all except 1st arg in last group (that treated as "cut all after 1st arg position")
  • '0123456789'.splice(0,2,null,3,1,null,5,2,'/',8); //return '24/7'
• if You pass multiple, you MUST check the sort of the positions left-to-right order by youreself!
• And if you dont want you MUST DO NOT use it like this:
  • '0123456789'.splice(4,-3,'what?'); //return "0123what?123456789"

If you have the OAuth PHP library installed, you don't have to worry about forming the request yourself.

$oauth = new OAuth($consumer_key, $consumer_secret, OAUTH_SIG_METHOD_HMACSHA1, OAUTH_AUTH_TYPE_URI);
$oauth->setToken($access_token, $access_secret);

$oauth->fetch("https://api.twitter.com/1.1/statuses/user_timeline.json");
$twitter_data = json_decode($oauth->getLastResponse());

print_r($twitter_data);

For more information, check out The docs or their example. You can use pecl install oauth to get the library.

Yeah, by using $(this), you enabled jQuery functionality for the object. By just using this, it only has generic Javascript functionality.

You can use .toString() to join an array with a comma.

var array = ['a', 'b', 'c'];
array.toString(); // result: a,b,c

Or, set the separator with array.join('; '); // result: a; b; c.

-XX:PermSize specifies the initial size that will be allocated during startup of the JVM. If necessary, the JVM will allocate up to -XX:MaxPermSize.

I had to spend a few hours to figure out why a[3] is changing on each iteration. This is the explanation at which I arrived.

There are two types of variables in PHP: normal variables and reference variables. If we assign a reference of a variable to another variable, the variable becomes a reference variable.

for example in

$a = array('zero', 'one', 'two', 'three');

if we do

$v = &$a[0]

the 0th element ($a[0]) becomes a reference variable. $v points towards that variable; therefore, if we make any change to $v, it will be reflected in $a[0] and vice versa.

now if we do

$v = &$a[1]

$a[1] will become a reference variable and $a[0] will become a normal variable (Since no one else is pointing to $a[0] it is converted to a normal variable. PHP is smart enough to make it a normal variable when no one else is pointing towards it)

This is what happens in the first loop

foreach ($a as &$v) {

}

After the last iteration $a[3] is a reference variable.

Since $v is pointing to $a[3] any change to $v results in a change to $a[3]

in the second loop,

foreach ($a as $v) {
  echo $v.'-'.$a[3].PHP_EOL;
}

in each iteration as $v changes, $a[3] changes. (because $v still points to $a[3]). This is the reason why $a[3] changes on each iteration.

In the iteration before the last iteration, $v is assigned the value 'two'. Since $v points to $a[3], $a[3] now gets the value 'two'. Keep this in mind.

In the last iteration, $v (which points to $a[3]) now has the value of 'two', because $a[3] was set to two in the previous iteration. two is printed. This explains why 'two' is repeated when $v is printed in the last iteration.

You can remove item from list view like this: or you can choose on your Button event which item have to be removed

public class Third extends ListActivity {
private ArrayAdapter<String> adapter;
private List<String> liste;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_third);
     String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
                "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
                "Linux", "OS/2" };
     liste = new ArrayList<String>();
     Collections.addAll(liste, values);
     adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, liste);
     setListAdapter(adapter);
}
 @Override
  protected void onListItemClick(ListView l, View v, int position, long id) {
     liste.remove(position);
     adapter.notifyDataSetChanged();
  }
}

I met this issue right on when I first install the Heroku's POSTGRES.app thing. After one morning trial and error i think this one line of code solved problem. As describe earlier, this is because postgresql does not have default role the first time it is set up. And we need to set that.

sovanlandy=# CREATE ROLE postgres LOGIN;

You must log in to your respective psql console to use this psql command.

Also noted that, if you already created the role 'postgre' but still get permission errors, you need to alter with command:

sovanlandy=# ALTER ROLE postgres LOGIN;

Hope it helps!

Today, I was testing this with iOS 9 Beta and found the solution.

To solve it, go to:

1. Settings -> General -> Profiles [Device Management on iOS 10]
2. Under ENTERPRISE APP, choose your current developer account name.
3. Tap Trust "Your developer account name"
4. Tap "Trust" in pop up.
5. Done

You don't need to convert int to String. Just use % 10 to get the last digit and then divide your int by 10 to get to the next one.

int temp = test;
ArrayList<Integer> array = new ArrayList<Integer>();
do{
    array.add(temp % 10);
    temp /= 10;
} while  (temp > 0);

This will leave you with ArrayList containing your digits in reverse order. You can easily revert it if it's required and convert it to int[].

In modern JS, this is simplified, and you can write something like this:

const firstWords = str =>_x000D_
  str .split (/\|/) .map (s => s .split (/\s+/) [0])_x000D_
_x000D_
const str = "Hello m|sss sss|mmm ss"_x000D_
_x000D_
console .log (firstWords (str))

We first split the string on the | and then split each string in the resulting array on any white space, keeping only the first one.

You can use also:

Collections.singletonList(Something.values())

Here is the Vanilla JavaScript solution for this issue -

First, we'll use Array.prototype.forEach() method, as

document.querySelectorAll('input[type=file]') returns an array like object.

Then we'll use the Function.prototype.call() method to assign each element in the array-like object to the this value in the .forEach method.

HTML

<form id="myForm">

    <input type="file" name="myFile" id="myFile_1">
    <input type="file" name="myFile" id="myFile_2">
    <input type="file" name="myFile" id="myFile_3">

    <button type="button" onclick="saveData()">Save</button>

</form>

JavaScript

 function saveData(){
     var data = new FormData(document.getElementById("myForm"));
     var inputs = document.querySelectorAll('input[type=file]');

     Array.prototype.forEach.call(inputs[0].files, function(index){
        data.append('files', index);
     });
     console.log(data.getAll("myFile"));
}

You can view the working example of the same HERE

For MAMP

1. Stop servers (but you may notice MySQL stays on)
2. Remove or rename /Applications/MAMP/tmp/mysql/ which holds the mysql.pid and mysql.sock.lock files
3. When you go back to Mamp, you'll see MySQL is now off. You can "Start Servers" again.

I recommend to use memcpy() for copying data. Also if we assign a buffer to another as array2 = array1 , both array have same memory and any change in the arrary1 deflects in array2 too. But we use memcpy, both buffer have different array. I recommend memcpy() because strcpy and related function do not copy NULL character.

$items=array(); 
$j=0; 

foreach($group_membership as $i => $username){ 
    $items[$j++]=$username; 
}

Just try the above in your code .

Here's a simple solution with lambdas:

root = Tk()
root.attributes("-fullscreen", True)
root.bind("<F11>", lambda event: root.attributes("-fullscreen",
                                    not root.attributes("-fullscreen")))
root.bind("<Escape>", lambda event: root.attributes("-fullscreen", False))
root.mainloop()

This will make the screen exit fullscreen when escape is pressed, and toggle fullscreen when F11 is pressed.

After trying almost every key on my keyboard:

C:\Users\Tim>cd ^
Mehr? Desktop

C:\Users\Tim\Desktop>

So it seems to be the ^ key.

There are several ways that you can transform data from multiple rows into columns.

Using PIVOT

In SQL Server you can use the PIVOT function to transform the data from rows to columns:

select Firstname, Amount, PostalCode, LastName, AccountNumber
from
(
  select value, columnname
  from yourtable
) d
pivot
(
  max(value)
  for columnname in (Firstname, Amount, PostalCode, LastName, AccountNumber)
) piv;

See Demo.

Pivot with unknown number of columnnames

If you have an unknown number of columnnames that you want to transpose, then you can use dynamic SQL:

DECLARE @cols AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX)

select @cols = STUFF((SELECT ',' + QUOTENAME(ColumnName) 
                    from yourtable
                    group by ColumnName, id
                    order by id
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

set @query = N'SELECT ' + @cols + N' from 
             (
                select value, ColumnName
                from yourtable
            ) x
            pivot 
            (
                max(value)
                for ColumnName in (' + @cols + N')
            ) p '

exec sp_executesql @query;

See Demo.

Using an aggregate function

If you do not want to use the PIVOT function, then you can use an aggregate function with a CASE expression:

select
  max(case when columnname = 'FirstName' then value end) Firstname,
  max(case when columnname = 'Amount' then value end) Amount,
  max(case when columnname = 'PostalCode' then value end) PostalCode,
  max(case when columnname = 'LastName' then value end) LastName,
  max(case when columnname = 'AccountNumber' then value end) AccountNumber
from yourtable

See Demo.

Using multiple joins

This could also be completed using multiple joins, but you will need some column to associate each of the rows which you do not have in your sample data. But the basic syntax would be:

select fn.value as FirstName,
  a.value as Amount,
  pc.value as PostalCode,
  ln.value as LastName,
  an.value as AccountNumber
from yourtable fn
left join yourtable a
  on fn.somecol = a.somecol
  and a.columnname = 'Amount'
left join yourtable pc
  on fn.somecol = pc.somecol
  and pc.columnname = 'PostalCode'
left join yourtable ln
  on fn.somecol = ln.somecol
  and ln.columnname = 'LastName'
left join yourtable an
  on fn.somecol = an.somecol
  and an.columnname = 'AccountNumber'
where fn.columnname = 'Firstname'

The Helvetica font does not come included with Windows, so to use it you must download it as a .ttf file. Then you can refer matplotlib to it like this (replace "crm10.ttf" with your file):

import os
from matplotlib import font_manager as fm, rcParams
import matplotlib.pyplot as plt

fig, ax = plt.subplots()

fpath = os.path.join(rcParams["datapath"], "fonts/ttf/cmr10.ttf")
prop = fm.FontProperties(fname=fpath)
fname = os.path.split(fpath)[1]
ax.set_title('This is a special font: {}'.format(fname), fontproperties=prop)
ax.set_xlabel('This is the default font')

plt.show()

print(fpath) will show you where you should put the .ttf.

You can see the output here: https://matplotlib.org/gallery/api/font_file.html

To retain the order use List or a LinkedHashSet.

In some situations we have to get image from drawable or raw folder using image name instead if generated id

// Image View Object 
        mIv = (ImageView) findViewById(R.id.xidIma);
// create context Object for  to Fetch  image from resourse 
Context mContext=getApplicationContext();

// getResources().getIdentifier("image_name","res_folder_name", package_name);

// find out below example 
    int i = mContext.getResources().getIdentifier("ic_launcher","raw", mContext.getPackageName());

// now we will get contsant id for that image       
        mIv.setBackgroundResource(i);

It would be helpful if you provided more information - e.g. what OS your using, what you want to accomplish, etc. But, generally speaking cURL is a very powerful command-line tool I frequently use (in linux) for imitating HTML requests:

For example:

curl --data "post1=value1&post2=value2&etc=valetc" http://host/resource

OR, for a RESTful API:

curl -X POST -d @file http://host/resource

You can check out more information here-> http://curl.haxx.se/

EDITs:

OK. So basically you're looking to stress test your REST server? Then cURL really isn't helpful unless you want to write your own load-testing program, even then sockets would be the way to go. I would suggest you check out Gatling. The Gatling documentation explains how to set up the tool, and from there your can run all kinds of GET, POST, PUT and DELETE requests.

Unfortunately, short of writing your own program - i.e. spawning a whole bunch of threads and inundating your REST server with different types of requests - you really have to rely on a stress/load-testing toolkit. Just using a REST client to send requests isn't going to put much stress on your server.

More EDITs

So in order to simulate a post request on a socket, you basically have to build the initial socket connection with the server. I am not a C# guy, so I can't tell you exactly how to do that; I'm sure there are 1001 C# socket tutorials on the web. With most RESTful APIs you usually need to provide a URI to tell the server what to do. For example, let's say your API manages a library, and you are using a POST request to tell the server to update information about a book with an id of '34'. Your URI might be

http://localhost/library/book/34

Therefore, you should open a connection to localhost on port 80 (or 8080, or whatever port your server is on), and pass along an HTML request header. Going with the library example above, your request header might look as follows:

POST library/book/34 HTTP/1.0\r\n
X-Requested-With: XMLHttpRequest\r\n
Content-Type: text/html\r\n
Referer: localhost\r\n
Content-length: 36\r\n\r\n
title=Learning+REST&author=Some+Name

From here, the server should shoot back a response header, followed by whatever the API is programed to tell the client - usually something to say the POST succeeded or failed. To stress test your API, you should essentially do this over and over again by creating a threaded process.

Also, if you are posting JSON data, you will have to alter your header and content accordingly. Frankly, if you are looking to do this quick and clean, I would suggest using python (or perl) which has several libraries for creating POST, PUT, GET and DELETE request, as well as POSTing and PUTing JSON data. Otherwise, you might end up doing more programming than stress testing. Hope this helps!

You can redirect anything or more URL via javascript, Just simple window.location.href with if else

Use this code,

<script>
if(window.location.href == 'old_url')
{
    window.location.href="new_url";
}


//Another url redirect
if(window.location.href == 'old_url2')
{
    window.location.href="new_url2";
}
</script>

You can redirect many URL's by this procedure. Thanks.

With CSS: table {float:left;}? ?

Try this:

myApp.service('userService', [
    '$http', '$q', '$rootScope', '$location', function($http, $q, $rootScope, $location) {
      var deferred= $q.defer();
      this.user = {
        access: false
      };
      try
      {
      this.isAuthenticated = function() {
        this.user = {
          first_name: 'First',
          last_name: 'Last',
          email: '[email protected]',
          access: 'institution'
        };
        deferred.resolve();
      };
    }
    catch
    {
        deferred.reject();
    }

    return deferred.promise;
  ]);

Try using Web API HttpClient

    static async Task RunAsync()
    {
        using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri("http://domain.com/");
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));


            // HTTP POST
            var obj = new MyObject() { Str = "MyString"};
            response = await client.PostAsJsonAsync("POST URL GOES HERE?", obj );
            if (response.IsSuccessStatusCode)
            {
                response.//.. Contains the returned content.
            }
        }
    }

You can find more details here Web API Clients

    $.ajax({
        url: '//freegeoip.net/json/',
        type: 'POST',
        dataType: 'jsonp',
        success: function(location) {
            alert(location.ip);
        }
    });

This will work https too

May be by:-

    for(Row row : sheet) {          
        for(Cell cell : row) {              
            System.out.print(cell.getStringCellValue());

        }
    }       

For specific type of cell you can try:

switch (cell.getCellType()) {
case Cell.CELL_TYPE_STRING:
    cellValue = cell.getStringCellValue();
    break;

case Cell.CELL_TYPE_FORMULA:
    cellValue = cell.getCellFormula();
    break;

case Cell.CELL_TYPE_NUMERIC:
    if (DateUtil.isCellDateFormatted(cell)) {
        cellValue = cell.getDateCellValue().toString();
    } else {
        cellValue = Double.toString(cell.getNumericCellValue());
    }
    break;

case Cell.CELL_TYPE_BLANK:
    cellValue = "";
    break;

case Cell.CELL_TYPE_BOOLEAN:
    cellValue = Boolean.toString(cell.getBooleanCellValue());
    break;

}

You also encounter this if you run an Application on a Scheduled Task in Non-Interactive mode.

As soon as you show a Dialog it throws the error:

Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

You can see its a MessageBox causing the problem in the stack trace:

at System.Windows.Forms.MessageBox.ShowCore(IWin32Window owner, String text, String caption, MessageBoxButtons buttons, MessageBoxIcon icon,  MessageBoxDefaultButton defaultButton, MessageBoxOptions options, Boolean showHelp)  

Solution

If you're running your app on a Scheduled Task send an email instead of showing a Dialog.

Either you can use the accessors provided by the Web Storage API or you could write a wrapper/adapter. From your stated issue with defineGetter/defineSetter is sounds like writing a wrapper/adapter is too much work for you.

I honestly don't know what to tell you. Maybe you could reevaluate your opinion of what is a "ridiculous limitation". The Web Storage API is just what it's supposed to be, a key/value store.

Here's an idea: try replacing everything that is not a dash char with empty string. Then count how many dashes remained.

select length(regexp_replace('123-345-566', '[^-]', '')) from dual

SELECT text 
FROM all_source
where name = 'FGETALGOGROUPKEY'
order by line

alternatively:

select dbms_metadata.get_ddl('FUNCTION', 'FGETALGOGROUPKEY')
from dual;

In Eclipse Neo
1. Window -> Show view -> Servers
2. Right click on server -> choose Properties
3. From General Tab -> Switch Location

You need to use the various Bootstrap 4 centering methods...

• Use text-center for inline elements.
• Use justify-content-center for flexbox elements (ie; form-inline)

https://codeply.com/go/Am5LvvjTxC

Also, to offset the column, the col-sm-* must be contained within a .row, and the .row must be in a container...

<section id="cover">
    <div id="cover-caption">
        <div id="container" class="container">
            <div class="row">
                <div class="col-sm-10 offset-sm-1 text-center">
                    <h1 class="display-3">Welcome to Bootstrap 4</h1>
                    <div class="info-form">
                        <form action="" class="form-inline justify-content-center">
                            <div class="form-group">
                                <label class="sr-only">Name</label>
                                <input type="text" class="form-control" placeholder="Jane Doe">
                            </div>
                            <div class="form-group">
                                <label class="sr-only">Email</label>
                                <input type="text" class="form-control" placeholder="[email protected]">
                            </div>
                            <button type="submit" class="btn btn-success ">okay, go!</button>
                        </form>
                    </div>
                    <br>

                    <a href="#nav-main" class="btn btn-secondary-outline btn-sm" role="button">?</a>

If you have UTF8, use this (actually works with SVG source), like:

btoa(unescape(encodeURIComponent(str)))

example:

 var imgsrc = 'data:image/svg+xml;base64,' + btoa(unescape(encodeURIComponent(markup)));
 var img = new Image(1, 1); // width, height values are optional params 
 img.src = imgsrc;

If you need to decode that base64, use this:

var str2 = decodeURIComponent(escape(window.atob(b64)));
console.log(str2);

Example:

var str = "äöüÄÖÜçéèñ";
var b64 = window.btoa(unescape(encodeURIComponent(str)))
console.log(b64);

var str2 = decodeURIComponent(escape(window.atob(b64)));
console.log(str2);

Note: if you need to get this to work in mobile-safari, you might need to strip all the white-space from the base64 data...

function b64_to_utf8( str ) {
    str = str.replace(/\s/g, '');    
    return decodeURIComponent(escape(window.atob( str )));
}

2017 Update

This problem has been bugging me again.
The simple truth is, atob doesn't really handle UTF8-strings - it's ASCII only.
Also, I wouldn't use bloatware like js-base64.

        c = c1 = c2 = 0;

        while (i < utftext.length)
        {
            c = utftext.charCodeAt(i);

            if (c < 128)
            {
                string += String.fromCharCode(c);
                i++;
            }
            else if ((c > 191) && (c < 224))
            {
                c2 = utftext.charCodeAt(i + 1);
                string += String.fromCharCode(((c & 31) << 6) | (c2 & 63));
                i += 2;
            }
            else
            {
                c2 = utftext.charCodeAt(i + 1);
                c3 = utftext.charCodeAt(i + 2);
                string += String.fromCharCode(((c & 15) << 12) | ((c2 & 63) << 6) | (c3 & 63));
                i += 3;

• For any character equal to or below 127 (hex 0x7F), the UTF-8 representation is one byte. It is just the lowest 7 bits of the full unicode value. This is also the same as the ASCII value.

• For characters equal to or below 2047 (hex 0x07FF), the UTF-8 representation is spread across two bytes. The first byte will have the two high bits set and the third bit clear (i.e. 0xC2 to 0xDF). The second byte will have the top bit set and the second bit clear (i.e. 0x80 to 0xBF).

• For all characters equal to or greater than 2048 but less that 65535 (0xFFFF), the UTF-8 representation is spread across three bytes.

Took me a while to find this out but if you a number stored in a variable, say x and you want to select it, use

document.querySelector('a[data-a= + CSS.escape(x) + ']'). 

This is due to some attribute naming specifications that I'm not yet very familiar with. Hope this will help someone.

This is an efficient solution:

#include <iostream>
int main() {
  int num = 20; 
  int numberOfDivisors = 1;

  for (int i = 2; i <= num; i++)
  {
    int exponent = 0;
    while (num % i == 0) {
        exponent++; 
        num /= i;
    }   
    numberOfDivisors *= (exponent+1);
  }

  std::cout << numberOfDivisors << std::endl;
  return 0;
}

Replace whatever is in the address bar with this:

javascript:document.getElementById('serverTime').innerHTML='[text here]';

Example.

As others have said, both == and .equals() work in most cases. The compile time certainty that you're not comparing completely different types of Objects that others have pointed out is valid and beneficial, however the particular kind of bug of comparing objects of two different compile time types would also be found by FindBugs (and probably by Eclipse/IntelliJ compile time inspections), so the Java compiler finding it doesn't add that much extra safety.

However:

1. The fact that == never throws NPE in my mind is a disadvantage of ==. There should hardly ever be a need for enum types to be null, since any extra state that you may want to express via null can just be added to the enum as an additional instance. If it is unexpectedly null, I'd rather have a NPE than == silently evaluating to false. Therefore I disagree with the it's safer at run-time opinion; it's better to get into the habit never to let enum values be @Nullable.
2. The argument that == is faster is also bogus. In most cases you'll call .equals() on a variable whose compile time type is the enum class, and in those cases the compiler can know that this is the same as == (because an enum's equals() method can not be overridden) and can optimize the function call away. I'm not sure if the compiler currently does this, but if it doesn't, and turns out to be a performance problem in Java overall, then I'd rather fix the compiler than have 100,000 Java programmers change their programming style to suit a particular compiler version's performance characteristics.
3. enums are Objects. For all other Object types the standard comparison is .equals(), not ==. I think it's dangerous to make an exception for enums because you might end up accidentally comparing Objects with == instead of equals(), especially if you refactor an enum into a non-enum class. In case of such a refactoring, the It works point from above is wrong. To convince yourself that a use of == is correct, you need to check whether value in question is either an enum or a primitive; if it was a non-enum class, it'd be wrong but easy to miss because the code would still compile. The only case when a use of .equals() would be wrong is if the values in question were primitives; in that case, the code wouldn't compile so it's much harder to miss. Hence, .equals() is much easier to identify as correct, and is safer against future refactorings.

I actually think that the Java language should have defined == on Objects to call .equals() on the left hand value, and introduce a separate operator for object identity, but that's not how Java was defined.

In summary, I still think the arguments are in favor of using .equals() for enum types.

My problem was the Dockerfile.txt needed to be converted to a Unix executable file. Once I did that that error went away.

You may need to remove the .txt portion before doing this, but on a mac go to terminal and cd into the directory where your Dockerfile is and the type

chmod +x "Dockerfile"

And then it will convert your file to a Unix executable file which can then be executed by the Docker build command.

Try like this

 $("#drop").change(function () {
        var end = this.value;
        var firstDropVal = $('#pick').val();
    });

Ubuntu comes with a version of PIP from precambrian and that's how you have to upgrade it if you do not want to spend hours and hours debugging pip related issues.

apt-get remove python-pip python3-pip
wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py
python3 get-pip.py

As you observed I included information for both Python 2.x and 3.x

Following Makefile code worked:

obj-m = hello.o

all:
    $(MAKE) -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules 

clean:
    $(MAKE) -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

I usually do this in the thread handling the json response:

try {
  Bitmap bitmap = BitmapFactory.decodeStream((InputStream)new URL(imageUrl).getContent());
} catch (MalformedURLException e) {
  e.printStackTrace();
} catch (IOException e) {
  e.printStackTrace();
}

If you need to do transformations on the image, you'll want to create a Drawable instead of a Bitmap.

Use IFERROR(value, value_if_error)

Also, there is the issue of possible 2.0 rollback. Trust me it has happened to me a couple of times so I am sure it has happened to others.

I also agree that abstraction is the best. Along with the fact, the original purpose of an ORM is to make RDBMS match up nicely to the OO concepts. However, if everything worked fine before LINQ by having to deviate a bit from OO concepts then screw 'em. Concepts and reality don't always fit well together. There is no room for militant zealots in IT.

Here's how I do it.

I decided to use IPrincipal instead of IIdentity because it means I don't have to implement both IIdentity and IPrincipal.

1. Create the interface

   interface ICustomPrincipal : IPrincipal
   {
       int Id { get; set; }
       string FirstName { get; set; }
       string LastName { get; set; }
   }
   

2. CustomPrincipal

   public class CustomPrincipal : ICustomPrincipal
   {
       public IIdentity Identity { get; private set; }
       public bool IsInRole(string role) { return false; }
   
       public CustomPrincipal(string email)
       {
           this.Identity = new GenericIdentity(email);
       }
   
       public int Id { get; set; }
       public string FirstName { get; set; }
       public string LastName { get; set; }
   }
   

3. CustomPrincipalSerializeModel - for serializing custom information into userdata field in FormsAuthenticationTicket object.

   public class CustomPrincipalSerializeModel
   {
       public int Id { get; set; }
       public string FirstName { get; set; }
       public string LastName { get; set; }
   }
   

4. LogIn method - setting up a cookie with custom information

   if (Membership.ValidateUser(viewModel.Email, viewModel.Password))
   {
       var user = userRepository.Users.Where(u => u.Email == viewModel.Email).First();
   
       CustomPrincipalSerializeModel serializeModel = new CustomPrincipalSerializeModel();
       serializeModel.Id = user.Id;
       serializeModel.FirstName = user.FirstName;
       serializeModel.LastName = user.LastName;
   
       JavaScriptSerializer serializer = new JavaScriptSerializer();
   
       string userData = serializer.Serialize(serializeModel);
   
       FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(
                1,
                viewModel.Email,
                DateTime.Now,
                DateTime.Now.AddMinutes(15),
                false,
                userData);
   
       string encTicket = FormsAuthentication.Encrypt(authTicket);
       HttpCookie faCookie = new HttpCookie(FormsAuthentication.FormsCookieName, encTicket);
       Response.Cookies.Add(faCookie);
   
       return RedirectToAction("Index", "Home");
   }
   

5. Global.asax.cs - Reading cookie and replacing HttpContext.User object, this is done by overriding PostAuthenticateRequest

   protected void Application_PostAuthenticateRequest(Object sender, EventArgs e)
   {
       HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName];
   
       if (authCookie != null)
       {
           FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);
   
           JavaScriptSerializer serializer = new JavaScriptSerializer();
   
           CustomPrincipalSerializeModel serializeModel = serializer.Deserialize<CustomPrincipalSerializeModel>(authTicket.UserData);
   
           CustomPrincipal newUser = new CustomPrincipal(authTicket.Name);
           newUser.Id = serializeModel.Id;
           newUser.FirstName = serializeModel.FirstName;
           newUser.LastName = serializeModel.LastName;
   
           HttpContext.Current.User = newUser;
       }
   }
   

6. Access in Razor views

   @((User as CustomPrincipal).Id)
   @((User as CustomPrincipal).FirstName)
   @((User as CustomPrincipal).LastName)
   

and in code:

    (User as CustomPrincipal).Id
    (User as CustomPrincipal).FirstName
    (User as CustomPrincipal).LastName

I think the code is self-explanatory. If it isn't, let me know.

Additionally to make the access even easier you can create a base controller and override the returned User object (HttpContext.User):

public class BaseController : Controller
{
    protected virtual new CustomPrincipal User
    {
        get { return HttpContext.User as CustomPrincipal; }
    }
}

and then, for each controller:

public class AccountController : BaseController
{
    // ...
}

which will allow you to access custom fields in code like this:

User.Id
User.FirstName
User.LastName

But this will not work inside views. For that you would need to create a custom WebViewPage implementation:

public abstract class BaseViewPage : WebViewPage
{
    public virtual new CustomPrincipal User
    {
        get { return base.User as CustomPrincipal; }
    }
}

public abstract class BaseViewPage<TModel> : WebViewPage<TModel>
{
    public virtual new CustomPrincipal User
    {
        get { return base.User as CustomPrincipal; }
    }
}

Make it a default page type in Views/web.config:

<pages pageBaseType="Your.Namespace.BaseViewPage">
  <namespaces>
    <add namespace="System.Web.Mvc" />
    <add namespace="System.Web.Mvc.Ajax" />
    <add namespace="System.Web.Mvc.Html" />
    <add namespace="System.Web.Routing" />
  </namespaces>
</pages>

and in views, you can access it like this:

@User.FirstName
@User.LastName

I would do it this way:

import sys

def main(argv):
    if len(argv) < 2:
        sys.stderr.write("Usage: %s <database>" % (argv[0],))
        return 1

    if not os.path.exists(argv[1]):
        sys.stderr.write("ERROR: Database %r was not found!" % (argv[1],))
        return 1

if __name__ == "__main__":
    sys.exit(main(sys.argv))

This allows main() to be imported into other modules if desired, and simplifies debugging because you can choose what argv should be.

You can use the .forEach() method of JavaScript for looping through JSON.

var datesBooking = [_x000D_
    {"date": "04\/24\/2018"},_x000D_
      {"date": "04\/25\/2018"}_x000D_
    ];_x000D_
    _x000D_
    datesBooking.forEach(function(data, index) {_x000D_
      console.log(data);_x000D_
    });

Do you want to do this?

SELECT id, parent_id, name, 
 (select Name from tbl where id = t.parent_id) parent_name
FROM tbl t start with id = 1 CONNECT BY PRIOR id = parent_id

Edit Another option based on OMG's one (but I think that will perform equally):

select 
           t1.id, 
           t1.parent_id, 
           t1.name,
           t2.name AS parent_name,
           t2.id AS parent_id
from 
    (select id, parent_id, name
    from tbl
    start with id = 1 
    connect by prior id = parent_id) t1
    left join
    tbl t2 on t2.id = t1.parent_id

Java supports closures just fine. It just doesn't support functions, so the syntax you're used to for closures is much more awkward and bulky: you have to wrap everything up in a class with a method. For example,

public Runnable foo(final int x) {
  return new Runnable() {
    public void run() {
      System.out.println(x);
    }
  };
}

Will return a Runnable object whose run() method "closes over" the x passed in, just like in any language that supports first-class functions and closures.

I think most solutions talk here about List Comprehension, but if you'd like to perform in place deletion and keep the space complexity to O(1); The solution is:

i = 0
for j in range(len(arr)):
if (arr[j] != 0):
    arr[i] = arr[j]
    i +=1
arr = arr[:i] 

If it helps...

I use the PHP function number_format() and the Narrow No-break Space ( ). It is often used as an unambiguous thousands separator.

echo number_format(200000, 0, "", " ");

Because IE8 has some problems to render the Narrow No-break Space, I changed it for a SPAN

echo "<span class='number'>".number_format(200000, 0, "", "<span></span>")."</span>";

.number SPAN{
    padding: 0 1px; 
}

CASE  
    WHEN last_name IS null THEN '' 
    ELSE ' ' + last_name 
END

After reading the accepted answer's comments, I tried the robocopy command, which worked for me (using the standard command prompt from Windows 7 64 bits SP 1):

robocopy source_dir dest_dir /s /e

public static void mulptiTransfer(WebDriver driver, By dropdownID, String text, By to)
{   
    String valuetext = null;
    WebElement element = locateElement(driver, dropdownID, 10);
    Select select = new Select(element);
    List<WebElement> options = element.findElements(By.tagName("option"));
    for (WebElement value: options) 
    {
        valuetext = value.getText();
        if (valuetext.equalsIgnoreCase(text))
        {
            try
            {
                select.selectByVisibleText(valuetext);
                locateElement(driver, to, 5).click();                           
                break;
            }
            catch (Exception e)
            {
                System.out.println(valuetext + "Value not found in Dropdown to Select");
            }       
        }
    }
}

As @Lighthart as shown, yes it's possible, although it adds significant fat to the controller and isn't DRY.

You should really define your own query in the entity repository, it's simple and best practice.

use Doctrine\ORM\EntityRepository;

class UserRepository extends EntityRepository
{
    public function findAll()
    {
        return $this->findBy(array(), array('username' => 'ASC'));
    }
}

Then you must tell your entity to look for queries in the repository:

/**
 * @ORM\Table(name="User")
 * @ORM\Entity(repositoryClass="Acme\UserBundle\Entity\Repository\UserRepository")
 */
class User
{
    ...
}

Finally, in your controller:

$this->getDoctrine()->getRepository('AcmeBundle:User')->findAll();

Should be

~/([^/]*)$~

Means: Match a / and then everything, that is not a / ([^/]*) until the end ($, "end"-anchor).

I use the ~ as delimiter, because now I don't need to escape the forward-slash /.

make sure """ comments are only a tab away and not 5 spaces

In some API maybe it does not work (like rabbitmq).

there is alternative:

curl http://username:[email protected]

curl http://admin:[email protected]

I am coming a bit late here, I don't get that much credit for it, I am just doing a mix of the answers below because I was forced to do that for a project.

So to answer the question : There is no such thing as this CSS property. I don't know why, but I think it's because they are afraid of a misused of this property, but I don't find any use case where it can be a serious problem.

Whatever, what are the solutions ?

Two tools will allow us to do that : media queries ans vw property

1) There is a "fool" solution consisting in making a media query for every step we eant in our css, changing font from a fixed amount to another fixed amount. It works, but it is very boring to do, and you don't have a smooth linear aspect.

2) As AlmostPitt explained, there is a brillant solution for the minima :

font-size: calc(7px + .5vw);

Minimum here would be 7px in addition to 0.5% of the view width. That is already really cool and working in most of cases. It does not require any media query, you just have to spend some time finding the right parameters.

As you noticed it is a linear function, basic maths learn you that two points already find you the parameters. Then just fix the font-size in px you want for very large screens and for mobile version, then calculate if you want to do a scientific method. Thought, it is absolutely not necessary and you can just go by trying.

3) Let's suppose you have a very boring client (like me) who absolutely wants a title to be one line and no more. If you used AlmostPitt solution, then you are in trouble because your font will keep growing, and if you have a fixed width container (like bootstrap stoping at 1140px or something in large windows). Here I suggest you to use also a media query. In fact you can just find the amout of px size maximum you can handle in your container before the aspect become unwanted (pxMax). This will be your maximum. Then you just have to find the exact screen width you must stop (wMax). (I let you inverse a linear function on your own).

After that just do

@media (min-width: [wMax]px) {
    h2{
        font-size: [pxMax]px;
    }
}

Then it is perfectly linear and your font-size stop growing ! Notice that you don't need to put your previous css property (calc...) in a media query under wMax because media query are considered as more imnportant and it will overwrite the previous property.

I don't think it is useful to make a snippet for this, as you would have trouble to make it to whole screen and it is not rocket science afterall.

Hope this could help others, and don't forget to thank AlmostPitt for his solution.

You say that if int(splitLine[0]) > int(lastUnix): is causing the trouble, but you don't actually show anything which suggests that. I think this line is the problem instead:

print 'Pulled', + stock

Do you see why this line could cause that error message? You want either

>>> stock = "AAAA"
>>> print 'Pulled', stock
Pulled AAAA

or

>>> print 'Pulled ' + stock
Pulled AAAA

not

>>> print 'Pulled', + stock
PulledTraceback (most recent call last):
  File "<ipython-input-5-7c26bb268609>", line 1, in <module>
    print 'Pulled', + stock
TypeError: bad operand type for unary +: 'str'

You're asking Python to apply the + symbol to a string like +23 makes a positive 23, and she's objecting.

The mugume david answer fails on an empty folder; Count is 1 instead of a 0 when looking for a pattern rather than all files. For example *.xml

This works for me:

attrib.exe /s ./*.xml | find /v "File not found - " | find /c /v ""

There was some good code posted that solved the problem better than !a != !b

Note that I had to add the BOOL_DETAIL_OPEN/CLOSE so it would work on MSVC 2010

   But what is this funny "(( a bool_xor b ))"? Well, you can create some
   macros that allow you such a strange syntax. Note that the
   double-brackets are part of the syntax and cannot be removed! The set of
   three macros (plus two internal helper macros) also provides bool_and
   and bool_or. That given, what is it good for? We have && and || already,
   why do we need such a stupid syntax? Well, && and || can't guarantee
   that the arguments are converted to bool and that you get a bool result.
     Think "operator overloads". Here's how the macros look like:

How about writing the data to a ByteArrayOutputStream instead of a FileOutputStream?

Otherwise, you could serialize the object using XMLEncoder, persist the XML, then deserialize via XMLDecoder.

Adding this just as an addition to @jimt's excellent answer:

one common way to define it all at initialization time is using an anonymous struct:

var opts = []struct {
    shortnm      byte
    longnm, help string
    needArg      bool
}{
    {'a', "multiple", "Usage for a", false},
    {
        shortnm: 'b',
        longnm:  "b-option",
        needArg: false,
        help:    "Usage for b",
    },
}

This is commonly used for testing as well to define few test cases and loop through them.

In VB:

from m in MyTable
take 10
select m.Foo

This assumes that MyTable implements IQueryable. You may have to access that through a DataContext or some other provider.

It also assumes that Foo is a column in MyTable that gets mapped to a property name.

See http://blogs.msdn.com/vbteam/archive/2008/01/08/converting-sql-to-linq-part-7-union-top-subqueries-bill-horst.aspx for more detail.

You should use Modernizr, it will add a class to the body tag.

also:

function getIeVersion()
{
  var rv = -1;
  if (navigator.appName == 'Microsoft Internet Explorer')
  {
    var ua = navigator.userAgent;
    var re  = new RegExp("MSIE ([0-9]{1,}[\.0-9]{0,})");
    if (re.exec(ua) != null)
      rv = parseFloat( RegExp.$1 );
  }
  else if (navigator.appName == 'Netscape')
  {
    var ua = navigator.userAgent;
    var re  = new RegExp("Trident/.*rv:([0-9]{1,}[\.0-9]{0,})");
    if (re.exec(ua) != null)
      rv = parseFloat( RegExp.$1 );
  }
  return rv;
}

Note that IE11 is still is in preview, and the user agent may change before release.

The User-agent string for IE 11 is currently this one :

Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv 11.0) like Gecko

Which means your can simply test, for versions 11.xx,

var isIE11 = !!navigator.userAgent.match(/Trident.*rv 11\./)

• the object which implements Comparable is Fegan.

The method compareTo you are overidding in it should have a Fegan object as a parameter whereas you are casting it to a FoodItems. Your compareTo implementation should describe how a Fegan compare to another Fegan.

• To actually do your sorting, you might want to make your FoodItems implement Comparable aswell and copy paste your actual compareTo logic in it.

I just tried set ~=%userprofile% and that works too if you want to keep using the same habit

You can then use %~% instead.

Since Java 5, you can use java.util.concurrent.TimeUnit to avoid the use of Magic Numbers like 1000 and 60 in your code.

By the way, you should take care to leap seconds in your computation: the last minute of a year may have an additional leap second so it indeed lasts 61 seconds instead of expected 60 seconds. The ISO specification even plan for possibly 61 seconds. You can find detail in java.util.Date javadoc.

Could be due to the TCP protocol turned off.

rm -rf some_dir

-r "recursive" -f "force" (suppress confirmation messages)

Be careful!

1. Open SQL server Management Studio.
2. Go to Connect to Server and select the Server Type as Integration Services and give the Server Name then click connect.
3. Go to Object Explorer on the left corner.
4. You can see the Stored Package folder in Object Explorer.
5. Expand the Stored Package folder, here you can see the SSIS interfaces.

A brute force change can be applied. This will work to change, but it's a longer process.

Go to the app folder src/app

1. Open this file: app.component.ts

2. Change this code styleUrls: ['./app.component.css'] to styleUrls: ['./app.component.scss']

3. Save and close.

In the same folder src/app

1. Rename the extension for the app.component.css file to (app.component.scss)

2. Follow this change for all the other components. (ex. home, about, contact, etc...)

The angular.json configuration file is next. It's located at the project root.

1. Search and Replace the css change it to (scss).

2. Save and close.

Lastly, Restart your ng serve -o.

If the compiler complains at you, go over the steps again.

Make sure to follow the steps in app/src closely.

To put it in another way, can we replicate the appearance of these text views without using the android:textAppearance attribute?

Like biegleux already said:

• small represents 14sp
• medium represents 18sp
• large represents 22sp

If you want to use the small, medium or large value on any text in your Android app, you can just create a dimens.xml file in your values folder and define the text size there with the following 3 lines:

<dimen name="text_size_small">14sp</dimen>
<dimen name="text_size_medium">18sp</dimen>
<dimen name="text_size_large">22sp</dimen>

Here is an example for a TextView with large text from the dimens.xml file:

<TextView
  android:id="@+id/hello_world"
  android:text="hello world"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:textSize="@dimen/text_size_large"/>

yq is a lightweight and portable command-line YAML processor

The aim of the project is to be the jq or sed of yaml files.

(https://github.com/mikefarah/yq#readme)

As an example (stolen straight from the documentation), given a sample.yaml file of:

---
bob:
  item1:
    cats: bananas
  item2:
    cats: apples

then

yq r sample.yaml bob.*.cats

will output

- bananas
- apples

Use bootstrap's .form-group class. Like this in your case:

<div class="col-md-6 form-group"></div>
<div class="col-md-6 form-group"></div>

Here is what I do. All of these instructions are based on my minimal experiences with working PACs, so YMMV.

Download your pac file via your pac URL. It's plain text and should be easy to open in a text editor.

Near the bottom, there's probably a section that says something like: return "PROXY w.x.y.z:a" where "w.x.y.z" is an ip address or username and "a" is a port number.

Write these down.

In a recent version of eclipse :

• Go to Window -> Preferences -> General -> Network Connections=
• Change the provider to "Manual"
• Select the "HTTP" line and click the edit button
• Add the IP address and port number above to the http line
• If you have to authenticate to use the proxy,
  • select "Requires Authentication"
  • type in your username. Note that if your authentication is on a Windows domain, you might have to prepend the domain name and a backslash (\) like: MYDOMAIN\MYUSERID
  • Type in your password
• Click OK
• Click Apply
• Click OK

At this point, you should be able to browse using the internal web browser (at least on http URLs).

Good luck.

Edit: Just so you know, it's WAY easier to use Nexus, one set of <mirror> tags and a single proxy setup (inside Nexus) to manage the proxy issues of Maven inside a firewall.

I would try the usual remedial things: - Run Rob Bovey's VBA Code Cleaner on your VBA Code - remove all addins on the users PC, particularly COM and .NET addins - Delete all the users .EXD files (MSoft Update incompatibilities) - Run Excel Detect & Repair on the users system - check the size of the user's .xlb file (should be 20-30K) - Reboot then delete all the users Temp files

Declare

public static int[] locations={1,2,3};

outside of the main method.

O[N^2] solutions are bad, especially when the data is already sorted, there is no need to do two nested loops for removing duplicates. One loop and comparing to the previous element will work great.

A simple solution with O[] of sort() would suffice. My solution is:

function sortUnique(arr, compareFunction) {
  let sorted = arr.sort(compareFunction);
  let result = sorted.filter(compareFunction
    ? function(val, i, a) { return (i == 0 || compareFunction(a[i-1], val) != 0); }
    : function(val, i, a) { return (i == 0 || a[i-1] !== val); }
  );
  return result;
}

BTW, can do something like this to have Array.sortUnique() method:

Array.prototype.sortUnique = function(compareFunction) {return sortUnique(this, compareFunction); }

Furthermore, sort() could be modified to remove second element if compare() function returns 0 (equal elements), though that code can become messy (need to revise loop boundaries in the flight). Besides, I stay away from making my own sort() functions in interpreted languages, since it will most certainly degrade the performance. So this addition is for the ECMA 2019+ consideration.

SHA isn't encryption, it's a one-way hash function. AES (Advanced_Encryption_Standard) is a symmetric encryption standard.

Here's a little thing I use just to get the registered paths in express 4.x

app._router.stack          // registered routes
  .filter(r => r.route)    // take out all the middleware
  .map(r => r.route.path)  // get all the paths

git log -p will generate the a patch (the diff) for every commit selected. For a single file, use git log --follow -p $file.

If you're looking for a particular change, use git bisect to find the change in log(n) views by splitting the number of commits in half until you find where what you're looking for changed.

Also consider looking back in history using git blame to follow changes to the line in question if you know what that is. This command shows the most recent revision to affect a certain line. You may have to go back a few versions to find the first change where something was introduced if somebody has tweaked it over time, but that could give you a good start.

Finally, gitk as a GUI does show me the patch immediately for any commit I click on.

Example :

Multicast sender that broadcasts to a multicast group:

#!/usr/bin/env python

import socket
import struct

def main():
  MCAST_GRP = '224.1.1.1'
  MCAST_PORT = 5007
  sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP)
  sock.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_TTL, 32)
  sock.sendto('Hello World!', (MCAST_GRP, MCAST_PORT))

if __name__ == '__main__':
  main()

Multicast receiver that reads from a multicast group and prints hex data to the console:

#!/usr/bin/env python

import socket
import binascii

def main():
  MCAST_GRP = '224.1.1.1' 
  MCAST_PORT = 5007
  sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP)
  try:
    sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
  except AttributeError:
    pass
  sock.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_TTL, 32) 
  sock.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_LOOP, 1)

  sock.bind((MCAST_GRP, MCAST_PORT))
  host = socket.gethostbyname(socket.gethostname())
  sock.setsockopt(socket.SOL_IP, socket.IP_MULTICAST_IF, socket.inet_aton(host))
  sock.setsockopt(socket.SOL_IP, socket.IP_ADD_MEMBERSHIP, 
                   socket.inet_aton(MCAST_GRP) + socket.inet_aton(host))

  while 1:
    try:
      data, addr = sock.recvfrom(1024)
    except socket.error, e:
      print 'Expection'
      hexdata = binascii.hexlify(data)
      print 'Data = %s' % hexdata

if __name__ == '__main__':
  main()

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

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

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

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

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

as it uses Moment.js. Documentation here.

Updated example:

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

All of the above show hard it can be to make a nice, flexible (or forbid an overloaded) function in LaTeX!!! (that TeX code looks like greek to me)

well, just to add my recent (albeit not as flexible) development, here's what I've recently used in my thesis doc, with

\usepackage{ifthen}  % provides conditonals...

Start the command, with the "optional" command set blank by default:

\newcommand {\figHoriz} [4] []  {

I then have the macro set a temporary variable, \temp{}, differently depending on whether or not the optional argument is blank. This could be extended to any passed argument.

\ifthenelse { \equal {#1} {} }  %if short caption not specified, use long caption (no slant)
    { \def\temp {\caption[#4]{\textsl{#4}}} }   % if #1 == blank
    { \def\temp {\caption[#1]{\textsl{#4}}} }   % else (not blank)

Then I run the macro using the \temp{} variable for the two cases. (Here it just sets the short-caption to equal the long caption if it wasn't specified by the user).

\begin{figure}[!]
    \begin{center}
        \includegraphics[width=350 pt]{#3}
        \temp   %see above for caption etc.
        \label{#2}
    \end{center}
\end{figure}
}

In this case I only check for the single, "optional" argument that \newcommand{} provides. If you were to set it up for, say, 3 "optional" args, you'd still have to send the 3 blank args... eg.

\MyCommand {first arg} {} {} {}

which is pretty silly, I know, but that's about as far as I'm going to go with LaTeX - it's just not that sensical once I start looking at TeX code... I do like Mr. Robertson's xparse method though, perhaps I'll try it...

Using jQuery it is very simple assuming the URL you wish to post to is on the same server or has implemented CORS

$(function() {
  $("#employeeLink").on("click",function(e) {
    e.preventDefault(); // cancel the link itself
    $.post(this.href,function(data) {
      $("#someContainer").html(data);
    });
  });
});

If you insist on using frames which I strongly discourage, have a form and submit it with the link

<form action="employee.action" method="post" target="myFrame" id="myForm"></form>

and use (in plain JS)

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the link
     document.getElementById("myForm").submit(); // but make sure nothing has name or ID="submit"
   });
 });

Without a form we need to make one

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the actual link
     var myForm = document.createElement("form");
     myForm.action=this.href;// the href of the link
     myForm.target="myFrame";
     myForm.method="POST";
     myForm.submit();
   });
 });

Swift 4+

extension String {
    func take(_ n: Int) -> String {
        guard n >= 0 else {
            fatalError("n should never negative")
        }
        let index = self.index(self.startIndex, offsetBy: min(n, self.count))
        return String(self[..<index])
    }
}

Returns a subsequence of the first n characters, or the entire string if the string is shorter. (inspired by: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.text/take.html)

Example:

let text = "Hello, World!"
let substring = text.take(5) //Hello

that value is contained in the variable $#

You have to rely on '#' but to make the task easier in vi you can perform the following (press escape first):

:10,20 s/^/#

with 10 and 20 being the start and end line numbers of the lines you want to comment out

and to undo when you are complete:

:10,20 s/^#//

In your code:

while(fscanf(fp,"%s %c",item,&status) == 1)  

why 1 and not 2? The scanf functions return the number of objects read.

You're checking the wrong method. Moq requires that you Setup (and then optionally Verify) the method in the dependency class.

You should be doing something more like this:

class MyClassTest
{
    [TestMethod]
    public void MyMethodTest()
    {
        string action = "test";
        Mock<SomeClass> mockSomeClass = new Mock<SomeClass>();

        mockSomeClass.Setup(mock => mock.DoSomething());

        MyClass myClass = new MyClass(mockSomeClass.Object);
        myClass.MyMethod(action);

        // Explicitly verify each expectation...
        mockSomeClass.Verify(mock => mock.DoSomething(), Times.Once());

        // ...or verify everything.
        // mockSomeClass.VerifyAll();
    }
}

In other words, you are verifying that calling MyClass#MyMethod, your class will definitely call SomeClass#DoSomething once in that process. Note that you don't need the Times argument; I was just demonstrating its value.

I've had this error as a result of trying to use a cloned VM that had the same SID as the domain. The two options to fix it were: sysprep (or rebuild) the database server OR dcpromo the DC down and back up to change the domain SID.

Most probably, your URL is not valid.

If it is a http/https URL, you can quickly check, by hammering the URL into a browser. If that does not display anything at all, you know that the URL is invalid.

I assume you are speaking of a remote repository. The URLs should look somewhat like these:

https://github.com/user/repo2.git if you're using HTTPS
[email protected]:user/repo2.git if you're using SSH

What about using the following:

int number = input.nextInt();
if (number < 0) {
    // negative
} else {
   // it's a positive
}

Kotlin way

editText.filters = arrayOf(InputFilter.LengthFilter(maxLength))

If someone is here who is using MySQL and felt that the code was working the previous day and now it doesn't, then I guess you must open MySQL CLI or MySQL Workbench and just make the connection to the database once. Once it gets connected, then the database also gets connected to the Java Application. I used to get the Hibernate Dialect error stating something wrong with com.mysql.jdbc.Driver. I think MySQL in some computers has a startup problem. This solved for me.

Use the splice method.

ArrayName.splice(indexValueOfArray,1);

This removes 1 item from the array starting at indexValueOfArray.

Do you need the second batch file to run asynchronously? Typically one batch file runs another synchronously with the call command, and the second one would share the first one's window.

You can use start /b second.bat to launch a second batch file asynchronously from your first that shares your first one's window. If both batch files write to the console simultaneously, the output will be overlapped and probably indecipherable. Also, you'll want to put an exit command at the end of your second batch file, or you'll be within a second cmd shell once everything is done.

I had the same problem. And finally it was a double include. One include in a file named X. And another include in a file named Y. Knowing that in file Y I had include ('X')

change to

fscanf(myFile, "%1d", &numberArray[i]);

Just another example where the value of a column from table 1 is inserted into a column in table 2:

UPDATE  Address
SET     Phone1 = sp.Phone
FROM    Address ad LEFT JOIN Speaker sp
ON      sp.AddressID = ad.ID
WHERE   sp.Phone <> '' 

You are not changing the value of line. It should be something like this.

import java.io.BufferedReader;
import java.io.FileReader;

public class InsertValuesIntoTestDb {

  @SuppressWarnings("rawtypes")
  public static void main(String[] args) throws Exception {
      String splitBy = ",";
      BufferedReader br = new BufferedReader(new FileReader("test.csv"));
      while((line = br.readLine()) != null){
           String[] b = line.split(splitBy);
           System.out.println(b[0]);
      }
      br.close();

  }
}

readLine returns each line and only returns null when there is nothing left. The above code sets line and then checks if it is null.

Another option would be to set a flag variable as a Boolean and then change that value based on your criteria.

Dim count as Integer 
Dim flag as Boolean

flag = True

While flag
    count = count + 1 

    If count = 10 Then
        'Set the flag to false         '
        flag = false
    End If 
Wend

This also works in Silverlight 5 (perhaps earlier as well but i haven't tested it). I used the relative source like this and it worked fine.

RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=telerik:RadGridView}"

It might be worth considering the use of a static factory method instead of constructor.

I'm saying instead, but obviously you can't replace the constructor. What you can do, though, is hide the constructor behind a static factory method. This way, we publish the static factory method as a part of the class API but at the same time we hide the constructor making it private or package private.

It's a reasonably simple solution, especially in comparison with the Builder pattern (as seen in Joshua Bloch's Effective Java 2nd Edition – beware, Gang of Four's Design Patterns define a completely different design pattern with the same name, so that might be slightly confusing) that implies creating a nested class, a builder object, etc.

This approach adds an extra layer of abstraction between you and your client, strengthening encapsulation and making changes down the road easier. It also gives you instance-control – since the objects are instantiated inside the class, you and not the client decide when and how these objects are created.

Finally, it makes testing easier – providing a dumb constructor, that just assigns the values to the fields, without performing any logic or validation, it allows you to introduce invalid state into your system to test how it behaves and reacts to that. You won't be able to do that if you're validating data in the constructor.

You can read much more about that in (already mentioned) Joshua Bloch's Effective Java 2nd Edition – it's an important tool in all developer's toolboxes and no wonder it's the subject of the 1st chapter of the book. ;-)

Following your example:

public class Book {

    private static final String DEFAULT_TITLE = "The Importance of Being Ernest";

    private final String title;
    private final String isbn;

    private Book(String title, String isbn) {
        this.title = title;
        this.isbn = isbn;
    }

    public static Book createBook(String title, String isbn) {
        return new Book(title, isbn);
    }

    public static Book createBookWithDefaultTitle(String isbn) {
        return new Book(DEFAULT_TITLE, isbn);
    }

    ...

}

Whichever way you choose, it's a good practice to have one main constructor, that just blindly assigns all the values, even if it's just used by another constructors.

For your command you also could refer to the following example:

sudo sh -c 'whoami; whoami'

It was giving 415 Http response Code as error,

So I added

httppost.addHeader("Content-Type", "text/xml; charset=utf-8");

Everything alright now, Http: 200

You can easily create timed redirections with JavaScript. But I suggest you to use location.replace('url') instead of location.href. It prevents to browser to push the site into the history. I found this JavaScript redirect tool. I think you could use this.

To do this, I had to come up with an intermediate data structure:

class KeyDataPoint {
    String key;
    DateTime timestamp;
    Number data;
    // obvious constructor and getters
}

With this in place, the approach is to "flatten" each MultiDataPoint into a list of (timestamp, key, data) triples and stream together all such triples from the list of MultiDataPoint.

Then, we apply a groupingBy operation on the string key in order to gather the data for each key together. Note that a simple groupingBy would result in a map from each string key to a list of the corresponding KeyDataPoint triples. We don't want the triples; we want DataPoint instances, which are (timestamp, data) pairs. To do this we apply a "downstream" collector of the groupingBy which is a mapping operation that constructs a new DataPoint by getting the right values from the KeyDataPoint triple. The downstream collector of the mapping operation is simply toList which collects the DataPoint objects of the same group into a list.

Now we have a Map<String, List<DataPoint>> and we want to convert it to a collection of DataSet objects. We simply stream out the map entries and construct DataSet objects, collect them into a list, and return it.

The code ends up looking like this:

Collection<DataSet> convertMultiDataPointToDataSet(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.getData().entrySet().stream()
                           .map(e -> new KeyDataPoint(e.getKey(), mdp.getTimestamp(), e.getValue())))
        .collect(groupingBy(KeyDataPoint::getKey,
                    mapping(kdp -> new DataPoint(kdp.getTimestamp(), kdp.getData()), toList())))
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

I took some liberties with constructors and getters, but I think they should be obvious.

Just add parameters, split by comma:

UPDATE tablename SET column1 = "value1", column2 = "value2" ....

A Y-combinator is a "functional" (a function that operates on other functions) that enables recursion, when you can't refer to the function from within itself. In computer-science theory, it generalizes recursion, abstracting its implementation, and thereby separating it from the actual work of the function in question. The benefit of not needing a compile-time name for the recursive function is sort of a bonus. =)

This is applicable in languages that support lambda functions. The expression-based nature of lambdas usually means that they cannot refer to themselves by name. And working around this by way of declaring the variable, refering to it, then assigning the lambda to it, to complete the self-reference loop, is brittle. The lambda variable can be copied, and the original variable re-assigned, which breaks the self-reference.

Y-combinators are cumbersome to implement, and often to use, in static-typed languages (which procedural languages often are), because usually typing restrictions require the number of arguments for the function in question to be known at compile time. This means that a y-combinator must be written for any argument count that one needs to use.

Below is an example of how the usage and working of a Y-Combinator, in C#.

Using a Y-combinator involves an "unusual" way of constructing a recursive function. First you must write your function as a piece of code that calls a pre-existing function, rather than itself:

// Factorial, if func does the same thing as this bit of code...
x == 0 ? 1: x * func(x - 1);

Then you turn that into a function that takes a function to call, and returns a function that does so. This is called a functional, because it takes one function, and performs an operation with it that results in another function.

// A function that creates a factorial, but only if you pass in
// a function that does what the inner function is doing.
Func<Func<Double, Double>, Func<Double, Double>> fact =
  (recurs) =>
    (x) =>
      x == 0 ? 1 : x * recurs(x - 1);

Now you have a function that takes a function, and returns another function that sort of looks like a factorial, but instead of calling itself, it calls the argument passed into the outer function. How do you make this the factorial? Pass the inner function to itself. The Y-Combinator does that, by being a function with a permanent name, which can introduce the recursion.

// One-argument Y-Combinator.
public static Func<T, TResult> Y<T, TResult>(Func<Func<T, TResult>, Func<T, TResult>> F)
{
  return
    t =>  // A function that...
      F(  // Calls the factorial creator, passing in...
        Y(F)  // The result of this same Y-combinator function call...
              // (Here is where the recursion is introduced.)
        )
      (t); // And passes the argument into the work function.
}

Rather than the factorial calling itself, what happens is that the factorial calls the factorial generator (returned by the recursive call to Y-Combinator). And depending on the current value of t the function returned from the generator will either call the generator again, with t - 1, or just return 1, terminating the recursion.

It's complicated and cryptic, but it all shakes out at run-time, and the key to its working is "deferred execution", and the breaking up of the recursion to span two functions. The inner F is passed as an argument, to be called in the next iteration, only if necessary.

See on the Wikipedia article on bootstrapping.

There is a section and links explaining what it means in Computing. It has four different uses in the field.

Here are some quotes, but for a more in depth explanation, and alternative meanings, consult the links above.

"...is a technique by which a simple computer program activates a more complicated system of programs."

"A different use of the term bootstrapping is to use a compiler to compile itself, by first writing a small part of a compiler of a new programming language in an existing language to compile more programs of the new compiler written in the new language."

Another solution that worked:

The data access object that actually throwed this exception is

public List<Foo> findAll() {
    return sessionFactory.getCurrentSession().createQuery("from foo").list();
}

The mistake I did in the above snippet is that I have used the table name foo inside createQuery. Instead, I got to use Foo, the actual class name.

public List<Foo> findAll() {
    return sessionFactory.getCurrentSession().createQuery("from Foo").list();

If you want to match anything after a word stop an not only at the start of the line you may use : \bstop.*\b - word followed by line

Or if you want to match the word in the string use \bstop[a-zA-Z]* - only the words starting with stop

Or the start of lines with stop ^stop[a-zA-Z]* for the word only - first word only
The whole line ^stop.* - first line of the string only

And if you want to match every string starting with stop including newlines use : /^stop.*/s - multiline string starting with stop

It's because you're trying to assign an object by reference. Remove the ampersand and your script should work as intended.

Remember to export your routes.js.

In routes.js, write your routes and all your code in this function module:

exports = function(app, passport) {

/* write here your code */ 

}

Another simple example.

For this sample we can use 100x100 DIV-box:

<div id="box" style="width: 100px; height: 100px; border: solid 1px red;">
 // Red box contents here...
</div>

And small jQuery trick:

<script type="text/javascript">
  jQuery("#box").bind("resize", function() {
    alert("Box was resized from 100x100 to 200x200");
  });
  jQuery("#box").width(200).height(200).trigger("resize");
</script>

Steps:

1. We created DIV block element for resizing operatios
2. Add simple JavaScript code with:
   • jQuery bind
   • jQuery resizer with trigger action "resize" - trigger is most important thing in my example
3. After resize you can check the browser alert information

That's all. ;-)

Firstly, try / except are not functions, but statements.

To convert a string (or any other type that can be converted) to an integer in Python, simply call the int() built-in function. int() will raise a ValueError if it fails and you should catch this specifically:

In Python 2.x:

>>> for value in '12345', 67890, 3.14, 42L, 0b010101, 0xFE, 'Not convertible':
...     try:
...         print '%s as an int is %d' % (str(value), int(value))
...     except ValueError as ex:
...         print '"%s" cannot be converted to an int: %s' % (value, ex)
...
12345 as an int is 12345
67890 as an int is 67890
3.14 as an int is 3
42 as an int is 42
21 as an int is 21
254 as an int is 254
"Not convertible" cannot be converted to an int: invalid literal for int() with base 10: 'Not convertible'

In Python 3.x

the syntax has changed slightly:

>>> for value in '12345', 67890, 3.14, 42, 0b010101, 0xFE, 'Not convertible':
...     try:
...         print('%s as an int is %d' % (str(value), int(value)))
...     except ValueError as ex:
...         print('"%s" cannot be converted to an int: %s' % (value, ex))
...
12345 as an int is 12345
67890 as an int is 67890
3.14 as an int is 3
42 as an int is 42
21 as an int is 21
254 as an int is 254
"Not convertible" cannot be converted to an int: invalid literal for int() with base 10: 'Not convertible'

As said in the documentation:

Must: The clause (query) must appear in matching documents.

Should: The clause (query) should appear in the matching document. In a boolean query with no must clauses, one or more should clauses must match a document. The minimum number of should clauses to match can be set using the minimum_should_match parameter.

In other words, results will have to be matched by all the queries present in the must clause ( or match at least one of the should clauses if there is no must clause.

Since you want your results to satisfy all the queries, you should use must.

You can indeed use filters inside a boolean query.

you can use localStorage for storing the json data:

the example is given below:-

let JSONDatas = [
    {"id": "Open"},
    {"id": "OpenNew", "label": "Open New"},
    {"id": "ZoomIn", "label": "Zoom In"},
    {"id": "ZoomOut", "label": "Zoom Out"},
    {"id": "Find", "label": "Find..."},
    {"id": "FindAgain", "label": "Find Again"},
    {"id": "Copy"},
    {"id": "CopyAgain", "label": "Copy Again"},
    {"id": "CopySVG", "label": "Copy SVG"},
    {"id": "ViewSVG", "label": "View SVG"}
]

localStorage.setItem("datas", JSON.stringify(JSONDatas));

let data = JSON.parse(localStorage.getItem("datas"));

console.log(data);

Late to the party, but maybe my solution will help somebody.

I haven't found any solution that works on a responsive website when the viewport changes or the layout is fluid.

So I've created a jQuery script for django-cms that is dynamically adapting to a changing viewport. I'm going to update this response as soon as I have the need for a modern variant of it that is more modular and has no jQuery dependency.

There is a ISO8601Utils utils class in com.google.gson.internal.bind.util package so if you use GSON in your app you can use this.

It supports millis and timezones so it's a pretty good option right out of the box.

That's a very complex question for a simple answer.

You may want to take a look at existing API frameworks, like Swagger Specification (OpenAPI), and services like apiary.io and apiblueprint.org.

Also, here's an example of the same REST API described, organized and even styled in three different ways. It may be a good start for you to learn from existing common ways.

• https://api.coinsecure.in/v1
• https://api.coinsecure.in/v1/originalUI
• https://api.coinsecure.in/v1/slateUI#!/Blockchain_Tools/v1_bitcoin_search_txid

At the very top level I think quality REST API docs require at least the following:

• a list of all your API endpoints (base/relative URLs)
• corresponding HTTP GET/POST/... method type for each endpoint
• request/response MIME-type (how to encode params and parse replies)
• a sample request/response, including HTTP headers
• type and format specified for all params, including those in the URL, body and headers
• a brief text description and important notes
• a short code snippet showing the use of the endpoint in popular web programming languages

Also there are a lot of JSON/XML-based doc frameworks which can parse your API definition or schema and generate a convenient set of docs for you. But the choice for a doc generation system depends on your project, language, development environment and many other things.

An XSD file is an XML Schema Definition and it is used to provide a standard method of checking that a given XML document conforms to what you expect.

Since there is no native way to do this ,Here is less intrusive solution i found (dont add any 'old' prototype methods):

var ListenerTracker=new function(){
    var is_active=false;
    // listener tracking datas
    var _elements_  =[];
    var _listeners_ =[];
    this.init=function(){
        if(!is_active){//avoid duplicate call
            intercep_events_listeners();
        }
        is_active=true;
    };
    // register individual element an returns its corresponding listeners
    var register_element=function(element){
        if(_elements_.indexOf(element)==-1){
            // NB : split by useCapture to make listener easier to find when removing
            var elt_listeners=[{/*useCapture=false*/},{/*useCapture=true*/}];
            _elements_.push(element);
            _listeners_.push(elt_listeners);
        }
        return _listeners_[_elements_.indexOf(element)];
    };
    var intercep_events_listeners = function(){
        // backup overrided methods
        var _super_={
            "addEventListener"      : HTMLElement.prototype.addEventListener,
            "removeEventListener"   : HTMLElement.prototype.removeEventListener
        };

        Element.prototype["addEventListener"]=function(type, listener, useCapture){
            var listeners=register_element(this);
            // add event before to avoid registering if an error is thrown
            _super_["addEventListener"].apply(this,arguments);
            // adapt to 'elt_listeners' index
            useCapture=useCapture?1:0;

            if(!listeners[useCapture][type])listeners[useCapture][type]=[];
            listeners[useCapture][type].push(listener);
        };
        Element.prototype["removeEventListener"]=function(type, listener, useCapture){
            var listeners=register_element(this);
            // add event before to avoid registering if an error is thrown
            _super_["removeEventListener"].apply(this,arguments);
            // adapt to 'elt_listeners' index
            useCapture=useCapture?1:0;
            if(!listeners[useCapture][type])return;
            var lid = listeners[useCapture][type].indexOf(listener);
            if(lid>-1)listeners[useCapture][type].splice(lid,1);
        };
        Element.prototype["getEventListeners"]=function(type){
            var listeners=register_element(this);
            // convert to listener datas list
            var result=[];
            for(var useCapture=0,list;list=listeners[useCapture];useCapture++){
                if(typeof(type)=="string"){// filtered by type
                    if(list[type]){
                        for(var id in list[type]){
                            result.push({"type":type,"listener":list[type][id],"useCapture":!!useCapture});
                        }
                    }
                }else{// all
                    for(var _type in list){
                        for(var id in list[_type]){
                            result.push({"type":_type,"listener":list[_type][id],"useCapture":!!useCapture});
                        }
                    }
                }
            }
            return result;
        };
    };
}();
ListenerTracker.init();

Thanks to Fredrik for pointing to the original bug in Eclipse. A comment by Richard Shu there describes several available solutions:

1. As Mauro said: "you have to remove and re-add the Eclipse Project Update site, so that its metadata are re-calculated." - works as workaround

2. Another workaround I found, is to edit the pre-defined URL link by adding just a trailing “/” to the update site URL.

3. The third workaround I discoverd accidentaly is to do nothing, but to uncheck the 'Contact all update sites during install to find required software' before checking the URL link.

Option #2 worked for me. I went to Window > Preferences > Install/Update > Available Software Sites, then for each enabled site I added a / to the end of the URL (if it wasn't there already), then clicked Reload.

You'll need to submit an ajax request to send the email without reloading the page. Take a look at http://api.jquery.com/jQuery.ajax/

Your code should be something along the lines of:

$('#submit').click(function() {
    $.ajax({
        url: 'send_email.php',
        type: 'POST',
        data: {
            email: '[email protected]',
            message: 'hello world!'
        },
        success: function(msg) {
            alert('Email Sent');
        }               
    });
});

The form will submit in the background to the send_email.php page which will need to handle the request and send the email.

The default path of Android SDK is /Users/<username>/Library/Android/sdk, you can refer to this post.

add this to your .bash_profile to add the environment variable

export PATH="/Users/<username>/Library/Android/sdk/tools:/Users/<username>/Library/Android/sdk/build-tools:${PATH}"

Then save the file.

load it

source ./.bash_profile 

There is also a combination, you can use a return value with a recordset:

--Stored Procedure--

CREATE PROCEDURE [TestProc]

AS
BEGIN

    DECLARE @Temp TABLE
    (
        [Name] VARCHAR(50)
    )

    INSERT INTO @Temp VALUES ('Mark') 
    INSERT INTO @Temp VALUES ('John') 
    INSERT INTO @Temp VALUES ('Jane') 
    INSERT INTO @Temp VALUES ('Mary') 

    -- Get recordset
    SELECT * FROM @Temp

    DECLARE @ReturnValue INT
    SELECT @ReturnValue = COUNT([Name]) FROM @Temp

    -- Return count
    RETURN @ReturnValue

END

--Calling Code--

DECLARE @SelectedValue int
EXEC @SelectedValue = [TestProc] 

SELECT @SelectedValue

--Results--

Your fundamental problem is that grep works one line at a time - so it cannot find a SELECT statement spread across lines.

Your second problem is that the regex you are using doesn't deal with the complexity of what can appear between SELECT and FROM - in particular, it omits commas, full stops (periods) and blanks, but also quotes and anything that can be inside a quoted string.

I would likely go with a Perl-based solution, having Perl read 'paragraphs' at a time and applying a regex to that. The downside is having to deal with the recursive search - there are modules to do that, of course, including the core module File::Find.

In outline, for a single file:

$/ = "\n\n";    # Paragraphs

while (<>)
{
     if ($_ =~ m/SELECT.*customerName.*FROM/mi)
     {
         printf file name
         go to next file
     }
}

That needs to be wrapped into a sub that is then invoked by the methods of File::Find.

Found it:

03-18 12:40:02.842: INFO/ActivityManager(68): Starting activity: Intent { action=android.intent.action.VIEW data=(URL TO A FLV FILE OF THE VIDEO) type=video/* comp={com.google.android.youtube/com.google.android.youtube.YouTubePlayer} (has extras) }

you can convert array with this function

function xml2array($xml){
$arr = array();

foreach ($xml->children() as $r)
{
    $t = array();
    if(count($r->children()) == 0)
    {
        $arr[$r->getName()] = strval($r);
    }
    else
    {
        $arr[$r->getName()][] = xml2array($r);
    }
}
return $arr;
}

\begin{equation}
\resizebox{.9\hsize}{!}{$A+B+C+D+E+F+G+H+I+J+K+L+M+N+O+P+Q+R+S+T+U+V+W+X+Y+Z$}
\end{equation}

or

\begin{equation}
\resizebox{.8\hsize}{!}{$A+B+C+D+E+F+G+H+I+J+K+L+M+N+O+P+Q+R+S+T+U+V+W+X+Y+Z$}
\end{equation}

You want to do this:

<html>
<body>
<?php

print '
<script type="text/javascript">
document.write("Hello World!")
</script>
';

?>
</body>
</html>

Let me seperate up everything and solve approach each problem in isolation:

Authentication

For authentication, baseauth has the advantage that it is a mature solution on the protocol level. This means a lot of "might crop up later" problems are already solved for you. For example, with BaseAuth, user agents know the password is a password so they don't cache it.

Auth server load

If you dispense a token to the user instead of caching the authentication on your server, you are still doing the same thing: Caching authentication information. The only difference is that you are turning the responsibility for the caching to the user. This seems like unnecessary labor for the user with no gains, so I recommend to handle this transparently on your server as you suggested.

Transmission Security

If can use an SSL connection, that's all there is to it, the connection is secure*. To prevent accidental multiple execution, you can filter multiple urls or ask users to include a random component ("nonce") in the URL.

url = username:[email protected]/api/call/nonce

If that is not possible, and the transmitted information is not secret, I recommend securing the request with a hash, as you suggested in the token approach. Since the hash provides the security, you could instruct your users to provide the hash as the baseauth password. For improved robustness, I recommend using a random string instead of the timestamp as a "nonce" to prevent replay attacks (two legit requests could be made during the same second). Instead of providing seperate "shared secret" and "api key" fields, you can simply use the api key as shared secret, and then use a salt that doesn't change to prevent rainbow table attacks. The username field seems like a good place to put the nonce too, since it is part of the auth. So now you have a clean call like this:

nonce = generate_secure_password(length: 16);
one_time_key = nonce + '-' + sha1(nonce+salt+shared_key);
url = username:[email protected]/api/call

It is true that this is a bit laborious. This is because you aren't using a protocol level solution (like SSL). So it might be a good idea to provide some kind of SDK to users so at least they don't have to go through it themselves. If you need to do it this way, I find the security level appropriate (just-right-kill).

Secure secret storage

It depends who you are trying to thwart. If you are preventing people with access to the user's phone from using your REST service in the user's name, then it would be a good idea to find some kind of keyring API on the target OS and have the SDK (or the implementor) store the key there. If that's not possible, you can at least make it a bit harder to get the secret by encrypting it, and storing the encrypted data and the encryption key in seperate places.

If you are trying to keep other software vendors from getting your API key to prevent the development of alternate clients, only the encrypt-and-store-seperately approach almost works. This is whitebox crypto, and to date, no one has come up with a truly secure solution to problems of this class. The least you can do is still issue a single key for each user so you can ban abused keys.

(*) EDIT: SSL connections should no longer be considered secure without taking additional steps to verify them.

Try something like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    Write-Host $_.Exception.ToString()
}

The exception is in the $_ variable. You might explore $_ like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    $_ | fl * -Force
}

I think it will give you all the info you need.

My rule: if there is some data that is not displayed, try to use -force.

I'd suggest doing something similar to:

function show_sub(cat) {
    if (!cat) {
        return false;
    }
    else if (document.getElementById(cat)) {
        var parent = document.getElementById(cat),
            sub = parent.getElementsByClassName('sub');
        if (sub[0].style.display == 'inline'){
            sub[0].style.display = 'none';
        }
        else {
            sub[0].style.display = 'inline';
        }
    }
}

document.getElementById('cat').onclick = function(){
    show_sub(this.id);
};????

JS Fiddle demo.

Though the above relies on the use of a class rather than a name attribute equal to sub.

As to why your original version "didn't work" (not, I must add, a particularly useful description of the problem), all I can suggest is that, in Chromium, the JavaScript console reported that:

Uncaught TypeError: Object # has no method 'getElementsByName'.

One approach to working around the older-IE family's limitations is to use a custom function to emulate getElementsByClassName(), albeit crudely:

function eBCN(elem,classN){
    if (!elem || !classN){
        return false;
    }
    else {
        var children = elem.childNodes;
        for (var i=0,len=children.length;i<len;i++){
            if (children[i].nodeType == 1
                &&
                children[i].className == classN){
                    var sub = children[i];
            }
        }
        return sub;
    }
}

function show_sub(cat) {
    if (!cat) {
        return false;
    }
    else if (document.getElementById(cat)) {
        var parent = document.getElementById(cat),
            sub = eBCN(parent,'sub');
        if (sub.style.display == 'inline'){
            sub.style.display = 'none';
        }
        else {
            sub.style.display = 'inline';
        }
    }
}

var D = document,
    listElems = D.getElementsByTagName('li');
for (var i=0,len=listElems.length;i<len;i++){
    listElems[i].onclick = function(){
        show_sub(this.id);
    };
}?

I took the Ned Rockson's version and adjusted it to allow upwards scrolls as well.

var smoothScroll = function(elementId) {
  var MIN_PIXELS_PER_STEP = 16;
  var MAX_SCROLL_STEPS = 30;
  var target = document.getElementById(elementId);
  var scrollContainer = target;
  do {
    scrollContainer = scrollContainer.parentNode;
    if (!scrollContainer) return;
    scrollContainer.scrollTop += 1;
  } while (scrollContainer.scrollTop === 0);

  var targetY = 0;
  do {
    if (target === scrollContainer) break;
    targetY += target.offsetTop;
  } while (target = target.offsetParent);

  var pixelsPerStep = Math.max(MIN_PIXELS_PER_STEP,
    Math.abs(targetY - scrollContainer.scrollTop) / MAX_SCROLL_STEPS);

  var isUp = targetY < scrollContainer.scrollTop;

  var stepFunc = function() {
    if (isUp) {
      scrollContainer.scrollTop = Math.max(targetY, scrollContainer.scrollTop - pixelsPerStep);
      if (scrollContainer.scrollTop <= targetY) {
        return;
      }
    } else {
        scrollContainer.scrollTop = Math.min(targetY, scrollContainer.scrollTop + pixelsPerStep);

      if (scrollContainer.scrollTop >= targetY) {
        return;
      }
    }

    window.requestAnimationFrame(stepFunc);
  };

  window.requestAnimationFrame(stepFunc);
};

Here's a one-liner slim way for layering text on top of an input in jQuery using ES6 syntax.

$('.input-group > input').focus(e => $(e.currentTarget).parent().find('.placeholder').hide()).blur(e => { if (!$(e.currentTarget).val()) $(e.currentTarget).parent().find('.placeholder').show(); });

* {
  font-family: sans-serif;
}

.input-group {
  position: relative;
}

.input-group > input {
  width: 150px;
  padding: 10px 0px 10px 25px;
}

.input-group > .placeholder {
  position: absolute;
  top: 50%;
  left: 25px;
  transform: translateY(-50%);
  color: #929292;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="input-group">
  <span class="placeholder">Username</span>
  <input>
</div>

You can achieve what you are saying by using Immediately Invoked Function Expression (IIFE)

render() {
    return (   
        <View style={styles.container}>
            {(() => {
              if (this.state == 'news'){
                  return (
                      <Text>data</Text>
                  )
              }
              
              return null;
            })()}
        </View>
    )
}

Here is the working example:

But, In your case, you can stick with the ternary operator

The biggest clue is the rows are all being returned on one line. This indicates line terminators are being ignored or are not present.

You can specify the line terminator for csv_reader. If you are on a mac the lines created will end with \rrather than the linux standard \n or better still the suspenders and belt approach of windows with \r\n.

pandas.read_csv(filename, sep='\t', lineterminator='\r')

You could also open all your data using the codecs package. This may increase robustness at the expense of document loading speed.

import codecs

doc = codecs.open('document','rU','UTF-16') #open for reading with "universal" type set

df = pandas.read_csv(doc, sep='\t')

If you're testing for all zeros to avoid a warning on another numpy function then wrapping the line in a try, except block will save having to do the test for zeros before the operation you're interested in i.e.

try: # removes output noise for empty slice 
    mean = np.mean(array)
except:
    mean = 0

Const: Absolute constant value during the application life time.

Readonly: It can be changed in running time.

If the user is interacting with another application, it may not be possible to bring yours to the front. As a general rule, a process can only expect to set the foreground window if that process is already the foreground process. (Microsoft documents the restrictions in the SetForegroundWindow() MSDN entry.) This is because:

1. The user "owns" the foreground. For example, it would be extremely annoying if another program stole the foreground while the user is typing, at the very least interrupting her workflow, and possibly causing unintended consequences as her keystrokes meant for one application are misinterpreted by the offender until she notices the change.
2. Imagine that each of two programs checks to see if its window is the foreground and attempts to set it to the foreground if it is not. As soon as the second program is running, the computer is rendered useless as the foreground bounces between the two at every task switch.

Do you mean like this

int index = 2;
string s = "hello";
Console.WriteLine(s[index]);

string also implements IEnumberable<char> so you can also enumerate it like this

foreach (char c in s)
    Console.WriteLine(c);

Being curious but still unable to find the answer to the performance topic of the question above, I wrote this gist for nodejs to test both the performance and reliability of all presented (and scored) solutions.

I've compared the wall times of a clone function creation and the execution of a clone. The results together with assertion errors are included in the gist's comment.

Plus my two cents (based on the author's suggestion):

clone0 cent (faster but uglier):

Function.prototype.clone = function() {
  var newfun;
  eval('newfun=' + this.toString());
  for (var key in this)
    newfun[key] = this[key];
  return newfun;
};

clone4 cent (slower but for those who dislike eval() for purposes known only to them and their ancestors):

Function.prototype.clone = function() {
  var newfun = new Function('return ' + this.toString())();
  for (var key in this)
    newfun[key] = this[key];
  return newfun;
};

As for the performance, if eval/new Function is slower than wrapper solution (and it really depends on the function body size), it gives you bare function clone (and I mean the true shallow clone with properties but unshared state) without unnecessary fuzz with hidden properties, wrapper functions and problems with stack.

Plus there is always one important factor you need to take into consideration: the less code, the less places for mistakes.

The downside of using the eval/new Function is that the clone and the original function will operate in different scopes. It won't work well with functions that are using scoped variables. The solutions using bind-like wrapping are scope independent.

Here's a solution using the new async/await syntax.

Be sure to check browser support as this is a language feature introduced with ECMAScript 6.

Utility function:

const delay = ms => new Promise(res => setTimeout(res, ms));

Usage:

const yourFunction = async () => {
  await delay(5000);
  console.log("Waited 5s");

  await delay(5000);
  console.log("Waited an additional 5s");
};

The advantage of this approach is that it makes your code look and behave like synchronous code.

First I had to delete the python folders in hidden folder user/appData (that was creating huge headaches), in addition to uninstalling Python. Then I installed WinPython Distribution: http://code.google.com/p/winpython/ which includes PIL

On linux, create file in /etc/default/locale with the following contents

LANG=en.utf8

and then use the source command to export this variable by running

source /etc/default/locale

The source command sets the variable permanently.

Objective-c:

NSString *day = [@"10/04/2011" componentsSeparatedByString:@"/"][0];

Swift:

var day: String = "10/04/2011".componentsSeparatedByString("/")[0]

In addition to Mark's answer, you also need to be aware of scope, which (as in C/C++) is specified using braces. So:

if (textBox1.Text == "" || textBox1.Text == String.Empty || textBox1.TextLength == 0)
    textBox3.Text += "[-] Listbox is Empty!!!!\r\n";
return;

will always return at that point. However:

if (textBox1.Text == "" || textBox1.Text == String.Empty || textBox1.TextLength == 0)
{
    textBox3.Text += "[-] Listbox is Empty!!!!\r\n";
    return;
}

will only return if it goes into that if statement.

 <a href="http://twitter.com/me" class="twitterbird" title="Twitter link"></a>

use a class for the link itself and forget the div

.twitterbird {
 margin-bottom: 10px;
 width: 160px;
 height:160px;
 display:block;
 background:transparent url('twitterbird.png') center top no-repeat;
}

.twitterbird:hover {
   background-image: url('twitterbird_hover.png');
}

The file location/path has to relative to your classpath locations. If resources directory is in your classpath you just need "app-context.xml" as file location.

The onclick property is all lower-case, and accepts a function, not a string.

document.getElementById("test").onclick = foo2;

My issue was that I was declaring two fonts, and scss seems to expect that you declare the name of the font.

after your @font-face{} you must declare $my-font: "OpenSans3.0 or whatever";

and this for each font-face.

:-)

First of all, you don't convert a DateTime object to some format, you display it in some format.

Given an instance of a DateTime object, you can get a formatted string in that way like this:

DateTime date = new DateTime(2011, 2, 19);
string formatted = date.ToString("dd/M/yyyy");

clone() creates a shallow copy. Which means the elements will not be cloned. (What if they didn't implement Cloneable?)

You may want to use Arrays.copyOf(..) for copying arrays instead of clone() (though cloning is fine for arrays, unlike for anything else)

If you want deep cloning, check this answer

A little example to illustrate the shallowness of clone() even if the elements are Cloneable:

ArrayList[] array = new ArrayList[] {new ArrayList(), new ArrayList()};
ArrayList[] clone = array.clone();
for (int i = 0; i < clone.length; i ++) {
    System.out.println(System.identityHashCode(array[i]));
    System.out.println(System.identityHashCode(clone[i]));
    System.out.println(System.identityHashCode(array[i].clone()));
    System.out.println("-----");
}

Prints:

4384790  
4384790
9634993  
-----  
1641745  
1641745  
11077203  
-----  

For future people struggling with a similar problem, the situation is that the compiler simply cannot find the type you are using (even if your Intelisense can find it).

This can be caused in many ways:

• You forgot to #include the header that defines it.
• Your inclusion guards (#ifndef BLAH_H) are defective (your #ifndef BLAH_H doesn't match your #define BALH_H due to a typo or copy+paste mistake).
• Your inclusion guards are accidentally used twice (two separate files both using #define MYHEADER_H, even if they are in separate directories)
• You forgot that you are using a template (eg. new Vector() should be new Vector<int>())
• The compiler is thinking you meant one scope when really you meant another (For example, if you have NamespaceA::NamespaceB, AND a <global scope>::NamespaceB, if you are already within NamespaceA, it'll look in NamespaceA::NamespaceB and not bother checking <global scope>::NamespaceB) unless you explicitly access it.
• You have a name clash (two entities with the same name, such as a class and an enum member).

To explicitly access something in the global namespace, prefix it with ::, as if the global namespace is a namespace with no name (e.g. ::MyType or ::MyNamespace::MyType).

There's still no simple answer. It depends on your scenario. MSDN has documentation to help you decide.

There are other options covered here. Instead of storing in the file system directly or in a BLOB, you can use the FileStream or File Table in SQL Server 2012. The advantages to File Table seem like a no-brainier (but admittedly I have no personal first-hand experience with them.)

The article is definitely worth a read.

An attempt without using a play field.

1. to win(your double)
2. if not, not to lose(opponent's double)
3. if not, do you already have a fork(have a double double)
4. if not, if opponent has a fork
   
   1. search in blocking points for possible double and fork(ultimate win)
   2. if not search forks in blocking points(which gives the opponent the most losing possibilities )
   3. if not only blocking points(not to lose)
5. if not search for double and fork(ultimate win)
6. if not search only for forks which gives opponent the most losing possibilities
7. if not search only for a double
8. if not dead end, tie, random.
9. if not(it means your first move)
   
   1. if it's the first move of the game;
      
      1. give the opponent the most losing possibility(the algorithm results in only corners which gives 7 losing point possibility to opponent)
      2. or for breaking boredom just random.
   2. if it's second move of the game;
      
      1. find only the not losing points(gives a little more options)
      2. or find the points in this list which has the best winning chance(it can be boring,cause it results in only all corners or adjacent corners or center)

Note: When you have double and forks, check if your double gives the opponent a double.if it gives, check if that your new mandatory point is included in your fork list.

It depends on the nature of your application. And, since you did not describe it in great detail, it is an impossible question to answer. I find Backbone to be the easiest, but I work in Angular all day. Performance is more up to the coder than the framework, in my opinion.

Are you doing heavy DOM manipulation? I would use jQuery and Backbone.

Very data driven app? Angular with its nice data binding.

Game programming? None - direct to canvas; maybe a game engine.

import java.sql.*;

class Time3 {

    public static void main(String args[]){ 
        String time1 = "01:03:23";
        String time2 = "02:32:00";
        long difference ;
        Time t1 = Time.valueOf(time1);
        Time t2 = Time.valueOf(time2);
        if(t2.getTime() >= t1.getTime()){
            difference = t2.getTime() - t1.getTime() -19800000;
        }
        else{
            difference = t1.getTime() - t2.getTime() -19800000;
        }

        java.sql.Time time = new java.sql.Time(difference); 
        System.out.println(time);
    } 

} 

datetime have comparison capability

>>> import datetime
>>> import time
>>> a =  datetime.datetime.now()
>>> time.sleep(2.0)
>>> b =  datetime.datetime.now()
>>> print a < b
True
>>> print a == b
False

 var miobj = [
  {"padreid":"0", "sw":"0", "dtip":"UNO", "datos":[]},
  {"padreid":"1", "sw":"0", "dtip":"DOS", "datos":[]}
 ];
 alert(miobj.length) //=== 2

but

 alert(miobj[0].length) //=== undefined

this function is very good

Object.prototype.count = function () {
    var count = 0;
    for(var prop in this) {
        if(this.hasOwnProperty(prop))
            count = count + 1;
    }
    return count;
}

alert(miobj.count()) // === 2
alert(miobj[0].count()) // === 4

If you're using prefill and signed chars, be careful not to append unwanted 'F's

char out_character = 0xBE; cout << setfill('0') << setw(2) << hex << unsigned short(out_character);

prints: ffbe

using int instead of short results in ffffffbe

To prevent the unwanted f's you can easily mask them out.

char out_character = 0xBE; cout << setfill('0') << setw(2) << hex << unsigned short(out_character) & 0xFF;

You can use a basic prepend operation on each line:

ls -1 | while read line ; do echo $line ; done

Or you can pipe the output to sed for more complex operations:

ls -1 | sed 's/^\(.*\)$/echo \1/'
