Darin Dimitrov's answer shows that OrderBy is slightly faster than List.Sort when faced with already-sorted input. I modified his code so it repeatedly sorts the unsorted data, and OrderBy is in most cases slightly slower.

Furthermore, the OrderBy test uses ToArray to force enumeration of the Linq enumerator, but that obviously returns a type (Person[]) which is different from the input type (List<Person>). I therefore re-ran the test using ToList rather than ToArray and got an even bigger difference:

Sort: 25175ms
OrderBy: 30259ms
OrderByWithToList: 31458ms

In GNU Awk 4.1.0 (released 2013) and later, it has the option of "inplace" file editing:

[...] The "inplace" extension, built using the new facility, can be used to simulate the GNU "sed -i" feature. [...]

Example usage:

$ gawk -i inplace '{ gsub(/foo/, "bar") }; { print }' file1 file2 file3

To keep the backup:

$ gawk -i inplace -v INPLACE_SUFFIX=.bak '{ gsub(/foo/, "bar") }
> { print }' file1 file2 file3

If you simply want to create a new branch without immediately changing to it, you could do the following:

git branch newbranch v1.0

This happened to me when I accidentally defined two entities with the same persistent database table. In one of the tables the column in question did exist, in the other not. When attempting to persist an object (of the type referring to the wrong underlying database table), this error occurred.

Like this

<?php

$prop = 'Name';

echo $obj->$prop;

Or, if you have control over the class, implement the ArrayAccess interface and just do this

echo $obj['Name'];

Quite an old article on mssqlcity attempts to explain the types of locks:

Shared locks are used for operations that do not change or update data, such as a SELECT statement.

Update locks are used when SQL Server intends to modify a page, and later promotes the update page lock to an exclusive page lock before actually making the changes.

Exclusive locks are used for the data modification operations, such as UPDATE, INSERT, or DELETE.

What it doesn't discuss are Intent (which basically is a modifier for these lock types). Intent (Shared/Exclusive) locks are locks held at a higher level than the real lock. So, for instance, if your transaction has an X lock on a row, it will also have an IX lock at the table level (which stops other transactions from attempting to obtain an incompatible lock at a higher level on the table (e.g. a schema modification lock) until your transaction completes or rolls back).

The concept of "sharing" a lock is quite straightforward - multiple transactions can have a Shared lock for the same resource, whereas only a single transaction may have an Exclusive lock, and an Exclusive lock precludes any transaction from obtaining or holding a Shared lock.

Simply specify the version in your current pom. The version specified here will override other.

Forcing a version
A version will always be honoured if it is declared in the current POM with a particular version - however, it should be noted that this will also affect other poms downstream if it is itself depended on using transitive dependencies.

A directive allows you to extend the HTML vocabulary in a declarative fashion for building web components. The ng-app attribute is a directive, so is ng-controller and all of the ng- prefixed attributes. Directives can be attributes, tags or even class names, comments.

How directives are born (compilation and instantiation)

Compile: We’ll use the compile function to both manipulate the DOM before it’s rendered and return a link function (that will handle the linking for us). This also is the place to put any methods that need to be shared around with all of the instances of this directive.

link: We’ll use the link function to register all listeners on a specific DOM element (that’s cloned from the template) and set up our bindings to the page.

If set in the compile() function they would only have been set once (which is often what you want). If set in the link() function they would be set every time the HTML element is bound to data in the object.

<div ng-repeat="i in [0,1,2]">
    <simple>
        <div>Inner content</div>
    </simple>
</div>

app.directive("simple", function(){
   return {
     restrict: "EA",
     transclude:true,
     template:"<div>{{label}}<div ng-transclude></div></div>",        
     compile: function(element, attributes){  
     return {
             pre: function(scope, element, attributes, controller, transcludeFn){

             },
             post: function(scope, element, attributes, controller, transcludeFn){

             }
         }
     },
     controller: function($scope){

     }
   };
});

Compile function returns the pre and post link function. In the pre link function we have the instance template and also the scope from the controller, but yet the template is not bound to scope and still don't have transcluded content.

Post link function is where post link is the last function to execute. Now the transclusion is complete, the template is linked to a scope, and the view will update with data bound values after the next digest cycle. The link option is just a shortcut to setting up a post-link function.

controller: The directive controller can be passed to another directive linking/compiling phase. It can be injected into other directices as a mean to use in inter-directive communication.

You have to specify the name of the directive to be required – It should be bound to same element or its parent. The name can be prefixed with:

? – Will not raise any error if a mentioned directive does not exist.
^ – Will look for the directive on parent elements, if not available on the same element.

Use square bracket [‘directive1', ‘directive2', ‘directive3'] to require multiple directives controller.

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

app.controller('MainCtrl', function($scope, $element) {
});

app.directive('parentDirective', function() {
  return {
    restrict: 'E',
    template: '<child-directive></child-directive>',
    controller: function($scope, $element){
      this.variable = "Hi Vinothbabu"
    }
  }
});

app.directive('childDirective', function() {
  return {
    restrict:  'E',
    template: '<h1>I am child</h1>',
    replace: true,
    require: '^parentDirective',
    link: function($scope, $element, attr, parentDirectCtrl){
      //you now have access to parentDirectCtrl.variable
    }
  }
});

Use git reset:

git reset --hard "Version 1.0 Revision 1.5"

(assuming that the specified string is the tag).

Recently we had a similar problem and had to solve it in a different way. We had to merge two branches up to two commits, which were not the heads of either branches:

branch A: A1 -> A2 -> A3 -> A4
branch B: B1 -> B2 -> B3 -> B4
branch C: C1 -> A2 -> B3 -> C2

For example, we had to merge branch A up to A2 and branch B up to B3. But branch C had cherry-picks from A and B. When using the SHA of A2 and B3 it looked like there was confusion because of the local branch C which had the same SHA.

To avoid any kind of ambiguity we removed branch C locally, and then created a branch AA starting from commit A2:

git co A
git co SHA-of-A2
git co -b AA

Then we created a branch BB from commit B3:

git co B
git co SHA-of-B3
git co -b BB

At that point we merged the two branches AA and BB. By removing branch C and then referencing the branches instead of the commits it worked.

It's not clear to me how much of this was superstition or what actually made it work, but this "long approach" may be helpful.

Try adding this to your web.xml:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/your-servlet-name.xml
    </param-value>

Following the thread from @James Cropcho's answer, I landed on the following which I found to be super easy to use. It is a binary tool, which is exactly what I was looking for: mongoeye.

Using this tool it took about 2 minutes to get my schema exported from command line.

Joda-Time

Using the Joda-Time 2.4 library. The DateTimeFormat class is a factory of DateTimeFormatter formatters. That class offers a forStyle method to access formatters appropriate to a Locale.

DateTimeFormatter formatter = DateTimeFormat.forStyle( "MM" ).withLocale( Java.util.Locale.CANADA_FRENCH );
String output = formatter.print( DateTime.now( DateTimeZone.forID( "America/Montreal" ) ) );

The argument with two letters specifies a format for the date portion and the time portion. Specify a character of 'S' for short style, 'M' for medium, 'L' for long, and 'F' for full. A date or time may be ommitted by specifying a style character '-' HYPHEN.

Note that we specified both a Locale and a time zone. Some people confuse the two.

• A time zone is an offset from UTC and a set of rules for Daylight Saving Time and other anomalies along with their historical changes.
• A Locale is a human language such as Français, plus a country code such as Canada that represents cultural practices including formatting of date-time strings.

We need all those pieces to properly generate a string representation of a date-time value.

To resolve the issue on a Debian/Ubuntu system modify the /etc/apache2/ports.conf settings file by adding NameVirtualHost *:443 to it. My ports.conf is the following at the moment:

# /etc/apache/ports.conf
# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default
# This is also true if you have upgraded from before 2.2.9-3 (i.e. from
# Debian etch). See /usr/share/doc/apache2.2-common/NEWS.Debian.gz and
# README.Debian.gz

NameVirtualHost *:80
Listen 80

<IfModule mod_ssl.c>
    # If you add NameVirtualHost *:443 here, you will also have to change
    # the VirtualHost statement in /etc/apache2/sites-available/default-ssl
    # to <VirtualHost *:443>
    # Server Name Indication for SSL named virtual hosts is currently not
    # supported by MSIE on Windows XP.

    NameVirtualHost *:443

    Listen 443
</IfModule>

<IfModule mod_gnutls.c>
    NameVirtualHost *:443
    Listen 443
</IfModule>

Furthermore ensure that 'sites-available/default-ssl' is not enabled, type a2dissite default-ssl to disable the site. While you're at it type a2dissite by itself to get a list and see if there is any other site settings that you have enabled that might be mapping onto port 443.

I've cloned a super handy tool that adds a context menu entry for assemblies in the windows explorer to show all available info:

I found a solution for my problem while writing my question !

Going into my remote session i tried two key combinations, and it solved the problem on my Desktop : Alt+Enter and Ctrl+Enter (i don't know which one solved the problem though)

I tried to reproduce the problem, but i couldn't... but i'm almost sure it's one of the key combinations described in the question above (since i experienced this problem several times)

So it seems the problem comes from the use of RDP (windows7 and 8)

Update 2017: Problem occurs on Windows 10 aswell.

What's FAT?

FAT may sound like a strange name for a file system, but it's actually an acronym for File Allocation Table. Introduced in 1981, FAT is ancient in computer terms. Because of its age, most operating systems, including Microsoft Windows NT®, Windows 98, the Macintosh OS, and some versions of UNIX, offer support for FAT.

The FAT file system limits filenames to the 8.3 naming convention, meaning that a filename can have no more than eight characters before the period and no more than three after. Filenames in a FAT file system must also begin with a letter or number, and they can't contain spaces. Filenames aren't case sensitive.

What About VFAT?

Perhaps you've also heard of a file system called VFAT. VFAT is an extension of the FAT file system and was introduced with Windows 95. VFAT maintains backward compatibility with FAT but relaxes the rules. For example, VFAT filenames can contain up to 255 characters, spaces, and multiple periods. Although VFAT preserves the case of filenames, it's not considered case sensitive.

When you create a long filename (longer than 8.3) with VFAT, the file system actually creates two different filenames. One is the actual long filename. This name is visible to Windows 95, Windows 98, and Windows NT (4.0 and later). The second filename is called an MS-DOS® alias. An MS-DOS alias is an abbreviated form of the long filename. The file system creates the MS-DOS alias by taking the first six characters of the long filename (not counting spaces), followed by the tilde [~] and a numeric trailer. For example, the filename Brien's Document.txt would have an alias of BRIEN'~1.txt.

An interesting side effect results from the way VFAT stores its long filenames. When you create a long filename with VFAT, it uses one directory entry for the MS-DOS alias and another entry for every 13 characters of the long filename. In theory, a single long filename could occupy up to 21 directory entries. The root directory has a limit of 512 files, but if you were to use the maximum length long filenames in the root directory, you could cut this limit to a mere 24 files. Therefore, you should use long filenames very sparingly in the root directory. Other directories aren't affected by this limit.

You may be wondering why we're discussing VFAT. The reason is it's becoming more common than FAT, but aside from the differences I mentioned above, VFAT has the same limitations. When you tell Windows NT to format a partition as FAT, it actually formats the partition as VFAT. The only time you'll have a true FAT partition under Windows NT 4.0 is when you use another operating system, such as MS-DOS, to format the partition.

FAT32

FAT32 is actually an extension of FAT and VFAT, first introduced with Windows 95 OEM Service Release 2 (OSR2). FAT32 greatly enhances the VFAT file system but it does have its drawbacks.

The greatest advantage to FAT32 is that it dramatically increases the amount of free hard disk space. To illustrate this point, consider that a FAT partition (also known as a FAT16 partition) allows only a certain number of clusters per partition. Therefore, as your partition size increases, the cluster size must also increase. For example, a 512-MB FAT partition has a cluster size of 8K, while a 2-GB partition has a cluster size of 32K.

This may not sound like a big deal until you consider that the FAT file system only works in single cluster increments. For example, on a 2-GB partition, a 1-byte file will occupy the entire cluster, thereby consuming 32K, or roughly 32,000 times the amount of space that the file should consume. This rule applies to every file on your hard disk, so you can see how much space can be wasted.

Converting a partition to FAT32 reduces the cluster size (and overcomes the 2-GB partition size limit). For partitions 8 GB and smaller, the cluster size is reduced to a mere 4K. As you can imagine, it's not uncommon to gain back hundreds of megabytes by converting a partition to FAT32, especially if the partition contains a lot of small files.

Note: This section of the quote/ article (1999) is out of date. Updated info quote below.

As I mentioned, FAT32 does have limitations. Unfortunately, it isn't compatible with any operating system other than Windows 98 and the OSR2 version of Windows 95. However, Windows 2000 will be able to read FAT32 partitions.

The other disadvantage is that your disk utilities and antivirus software must be FAT32-aware. Otherwise, they could interpret the new file structure as an error and try to correct it, thus destroying data in the process.

Finally, I should mention that converting to FAT32 is a one-way process. Once you've converted to FAT32, you can't convert the partition back to FAT16. Therefore, before converting to FAT32, you need to consider whether the computer will ever be used in a dual-boot environment. I should also point out that although other operating systems such as Windows NT can't directly read a FAT32 partition, they can read it across the network. Therefore, it's no problem to share information stored on a FAT32 partition with other computers on a network that run older operating systems.

Updated mentioned in comment by Doktor-J (assimilated to update out of date answer in case comment is ever lost):

I'd just like to point out that most modern operating systems (WinXP/Vista/7/8, MacOS X, most if not all Linux variants) can read FAT32, contrary to what the second-to-last paragraph suggests.

The original article was written in 1999, and being posted on a Microsoft website, probably wasn't concerned with non-Microsoft operating systems anyways.

The operating systems "excluded" by that paragraph are probably the original Windows 95, Windows NT 4.0, Windows 3.1, DOS, etc.

This is a solution that means that as you add new stored procedures to the schema, users can execute them without having to call grant execute on the new stored procedure:

IF  EXISTS (SELECT * FROM sys.database_principals WHERE name = N'asp_net')
DROP USER asp_net
GO

IF  EXISTS (SELECT * FROM sys.database_principals 
WHERE name = N'db_execproc' AND type = 'R')
DROP ROLE [db_execproc]
GO

--Create a database role....
CREATE ROLE [db_execproc] AUTHORIZATION [dbo]
GO

--...with EXECUTE permission at the schema level...
GRANT EXECUTE ON SCHEMA::dbo TO db_execproc;
GO

--http://www.patrickkeisler.com/2012/10/grant-execute-permission-on-all-stored.html
--Any stored procedures that are created in the dbo schema can be 
--executed by users who are members of the db_execproc database role

--...add a user e.g. for the NETWORK SERVICE login that asp.net uses
CREATE USER asp_net 
FOR LOGIN [NT AUTHORITY\NETWORK SERVICE] 
WITH DEFAULT_SCHEMA=[dbo]
GO

--...and add them to the roles you need
EXEC sp_addrolemember N'db_execproc', 'asp_net';
EXEC sp_addrolemember N'db_datareader', 'asp_net';
EXEC sp_addrolemember N'db_datawriter', 'asp_net';
GO

Reference: Grant Execute Permission on All Stored Procedures

Assuming this example HTML:

<input type="text" name="email" id="email" />
<input type="text" name="first_name" id="first_name" />
<input type="text" name="last_name" id="last_name" />

You could have this javascript:

$("#email").bind("change", function(e){
  $.getJSON("http://yourwebsite.com/lokup.php?email=" + $("#email").val(),
        function(data){
          $.each(data, function(i,item){
            if (item.field == "first_name") {
              $("#first_name").val(item.value);
            } else if (item.field == "last_name") {
              $("#last_name").val(item.value);
            }
          });
        });
});

Then just you have a PHP script (in this case lookup.php) that takes an email in the query string and returns a JSON formatted array back with the values you want to access. This is the part that actually hits the database to look up the values:

<?php
//look up the record based on email and get the firstname and lastname
...

//build the JSON array for return
$json = array(array('field' => 'first_name', 
                    'value' => $firstName), 
              array('field' => 'last_name', 
                    'value' => $last_name));
echo json_encode($json );
?>

You'll want to do other things like sanitize the email input, etc, but should get you going in the right direction.

Broadcast receivers receive events of a certain type. I don't think you can invoke them by class name.

First, your IntentFilter must contain an event.

static final String SOME_ACTION = "com.yourcompany.yourapp.SOME_ACTION";
IntentFilter intentFilter = new IntentFilter(SOME_ACTION);

Second, when you send a broadcast, use this same action:

Intent i = new Intent(SOME_ACTION);
sendBroadcast(i);

Third, do you really need MyIntentService to be inline? Static? [EDIT] I discovered that MyIntentSerivce MUST be static if it is inline.

Fourth, is your service declared in the AndroidManifest.xml?

I suspect everyone has an answer already, though in case someone comes looking, dplyr na_if() would be (from my perspective) the more efficient of those mentioned:

# Import CSV, convert all 'blank' cells to NA
dat <- read.csv("data2.csv") %>% na_if("")

Here is an additional approach leveraging readr's read_delim function. I just picked-up (probably widely know, but I'll archive here for future users). This is very straight forward and more versatile than the above, as you can capture all types of blank and NA related values in your csv file:

dat <- read_csv("data2.csv", na = c("", "NA", "N/A"))

Note the underscore in readr's version versus Base R "." in read_csv.

Hopefully this helps someone who wanders upon the post!

put this in your "head" of your index.html

 <style>
  html body{
    left: 0;
    right: 0;
    bottom: 0;
    top: 0;
    margin: 0;
  }
  </style>

To remove spaces... please use LTRIM/RTRIM

 LTRIM(String)
 RTRIM(String)

The String parameter that is passed to the functions can be a column name, a variable, a literal string or the output of a user defined function or scalar query.

SELECT LTRIM(' spaces at start')
SELECT RTRIM(FirstName) FROM Customers

The problem is that you can't use a list as the key in a dict, since dict keys need to be immutable. Use a tuple instead.

This is a list:

[x, y]

This is a tuple:

(x, y)

Note that in most cases, the ( and ) are optional, since , is what actually defines a tuple (as long as it's not surrounded by [] or {}, or used as a function argument).

You might find the section on tuples in the Python tutorial useful:

Though tuples may seem similar to lists, they are often used in different situations and for different purposes. Tuples are immutable, and usually contain an heterogeneous sequence of elements that are accessed via unpacking (see later in this section) or indexing (or even by attribute in the case of namedtuples). Lists are mutable, and their elements are usually homogeneous and are accessed by iterating over the list.

And in the section on dictionaries:

Unlike sequences, which are indexed by a range of numbers, dictionaries are indexed by keys, which can be any immutable type; strings and numbers can always be keys. Tuples can be used as keys if they contain only strings, numbers, or tuples; if a tuple contains any mutable object either directly or indirectly, it cannot be used as a key. You can’t use lists as keys, since lists can be modified in place using index assignments, slice assignments, or methods like append() and extend().

In case you're wondering what the error message means, it's complaining because there's no built-in hash function for lists (by design), and dictionaries are implemented as hash tables.

No.

The content-type should be whatever it is known to be, if you know it. application/octet-stream is defined as "arbitrary binary data" in RFC 2046, and there's a definite overlap here of it being appropriate for entities whose sole intended purpose is to be saved to disk, and from that point on be outside of anything "webby". Or to look at it from another direction; the only thing one can safely do with application/octet-stream is to save it to file and hope someone else knows what it's for.

You can combine the use of Content-Disposition with other content-types, such as image/png or even text/html to indicate you want saving rather than display. It used to be the case that some browsers would ignore it in the case of text/html but I think this was some long time ago at this point (and I'm going to bed soon so I'm not going to start testing a whole bunch of browsers right now; maybe later).

RFC 2616 also mentions the possibility of extension tokens, and these days most browsers recognise inline to mean you do want the entity displayed if possible (that is, if it's a type the browser knows how to display, otherwise it's got no choice in the matter). This is of course the default behaviour anyway, but it means that you can include the filename part of the header, which browsers will use (perhaps with some adjustment so file-extensions match local system norms for the content-type in question, perhaps not) as the suggestion if the user tries to save.

Hence:

Content-Type: application/octet-stream
Content-Disposition: attachment; filename="picture.png"

Means "I don't know what the hell this is. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: attachment; filename="picture.png"

Means "This is a PNG image. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: inline; filename="picture.png"

Means "This is a PNG image. Please display it unless you don't know how to display PNG images. Otherwise, or if the user chooses to save it, we recommend the name picture.png for the file you save it as".

Of those browsers that recognise inline some would always use it, while others would use it if the user had selected "save link as" but not if they'd selected "save" while viewing (or at least IE used to be like that, it may have changed some years ago).

Suppose you have data in A1:A10 and B1:B10 and you want to highlight which values in A1:A10 do not appear in B1:B10.

Try as follows:

1. Format > Conditional Formating...
2. Select 'Formula Is' from drop down menu

3. Enter the following formula:

   =ISERROR(MATCH(A1,$B$1:$B$10,0))

4. Now select the format you want to highlight the values in col A that do not appear in col B

This will highlight any value in Col A that does not appear in Col B.

A bit late to the party, but JQuery change inner text but preserve html has at least one approach not mentioned here:

var $td = $("#demoTable td");
$td.html($td.html().replace('Tap on APN and Enter', 'new text'));

Without fixing the text, you could use (snother)[https://stackoverflow.com/a/37828788/1587329]:

var $a = $('#demoTable td');
var inner = '';
$a.children.html().each(function() {
    inner = inner + this.outerHTML;
});
$a.html('New text' + inner);

As mentioned by others the error may occur if the url is wrong.

However, the error may also occur if the repo is a private repo and you do not have access or wrong credentials.

Instead of

git clone https://github.com/NAME/repo.git

try

git clone https://username:[email protected]/NAME/repo.git

You can also use

git clone https://[email protected]/NAME/repo.git

and git will prompt for the password (thanks to leanne for providing this hint in the comments).

If you run the mount command with no command-line arguments, which displays the file systems mounted on your system, you’ll notice a line that looks something like this: none on /dev/pts type devpts (rw,gid=5,mode=620) This indicates that a special type of file system, devpts , is mounted at /dev/pts .This file system, which isn’t associated with any hardware device, is a “magic” file system that is created by the Linux kernel. It’s similar to the /proc file system

Like the /dev directory, /dev/pts contains entries corresponding to devices. But unlike /dev , which is an ordinary directory, /dev/pts is a special directory that is cre- ated dynamically by the Linux kernel.The contents of the directory vary with time and reflect the state of the running system. The entries in /dev/pts correspond to pseudo-terminals (or pseudo-TTYs, or PTYs).

Linux creates a PTY for every new terminal window you open and displays a corre- sponding entry in /dev/pts .The PTY device acts like a terminal device—it accepts input from the keyboard and displays text output from the programs that run in it. PTYs are numbered, and the PTY number is the name of the corresponding entry in /dev/pts .

For example, if the new terminal window’s PTY number is 7, invoke this command from another window: % echo ‘I am a virtual di ’ > /dev/pts/7 The output appears in the new terminal window.

Something else to check is make sure viewstate is on (I just solved this yesterday). If you don't have viewstate on, the gridview will be blank until you load it again.

Return your promise , return deferred.promise.
It is the promise API that has the 'then' method.

https://docs.angularjs.org/api/ng/service/$q

Calling resolve does not return a promise it only signals the promise that the promise is resolved so it can execute the 'then' logic.

Basic pattern as follows, rinse and repeat

or an ORACLE version:

For majority of us OrElse and AndAlso will do the trick except for a few confusing exceptions (less than 1% where we may have to use Or and And).

Try not to get carried away by people showing off their boolean logics and making it look like a rocket science.

It's quite simple and straight forward and occasionally your system may not work as expected because it doesn't like your logic in the first place. And yet your brain keeps telling you that his logic is 100% tested and proven and it should work. At that very moment stop trusting your brain and ask him to think again or (not OrElse or maybe OrElse) you force yourself to look for another job that doesn't require much logic.

You can take the sets of the columns and just subtract the smaller set from the larger set:

distinct_values = set(df['a'])-set(df['b'])

My best guess is that they ran out of brackets and didn't think it would be useful enough to warrent adding an "ugly" syntax ...

In my experience, the fastest method is

UPDATE table_name SET field = REPLACE(field, 'foo', 'bar') WHERE field LIKE '%foo%';

The INSTR() way is the second-fastest and omitting the WHERE clause altogether is slowest, even if the column is not indexed.

You want to use the gesturestart, gesturechange, and gestureend events. These get triggered any time 2 or more fingers touch the screen.

Depending on what you need to do with the pinch gesture, your approach will need to be adjusted. The scale multiplier can be examined to determine how dramatic the user's pinch gesture was. See Apple's TouchEvent documentation for details about how the scale property will behave.

node.addEventListener('gestureend', function(e) {
    if (e.scale < 1.0) {
        // User moved fingers closer together
    } else if (e.scale > 1.0) {
        // User moved fingers further apart
    }
}, false);

You could also intercept the gesturechange event to detect a pinch as it happens if you need it to make your app feel more responsive.

Relying on JQuery Datepicker, but it could be done easily:

var mydate = new Date();
$.datepicker.formatDate('yy-mm-dd', mydate);

Use this code:

        SqlConnection conn = new SqlConnection();
        conn.ConnectionString = @"Data Source=HOSTNAME\SQLEXPRESS; Initial Catalog=DataBase; Integrated Security=True";
        conn.Open();
        MessageBox.Show("Connection Open  !");
        conn.Close();

In file /etc/ssh/sshd_config

# Change to no to disable tunnelled clear text passwords
#PasswordAuthentication no

Uncomment the second line, and, if needed, change yes to no.

Then run

service ssh restart

If you are encountering this issue with an application installed via conda, the solution (as stated in this bug report) is simply to install setup-tools with:

conda install setuptools

Eclipse can't work out what you want to run and since you've not run anything before, it can't try re-running that either.

Instead of clicking the green 'run' button, click the dropdown next to it and chose Run Configurations. On the Android tab, make sure it's set to your project. In the Target tab, set the tick box and options as appropriate to target your device. Then click Run. Keep an eye on your Console tab in Eclipse - that'll let you know what's going on. Once you've got your run configuration set, you can just hit the green 'run' button next time.

Sometimes getting everything to talk to your device can be problematic to begin with. Consider using an AVD (i.e. an emulator) as alternative, at least to begin with if you have problems. You can easily create one from the menu Window -> Android Virtual Device Manager within Eclipse.

To view the progress of your project being installed and started on your device, check the console. It's a panel within Eclipse with the tabs Problems/Javadoc/Declaration/Console/LogCat etc. It may be minimised - check the tray in the bottom right. Or just use Window/Show View/Console from the menu to make it come to the front. There are two consoles, Android and DDMS - there is a dropdown by its icon where you can switch.

According to JavaDocs, you can do this:

WebElement input = divA.findElement(By.xpath(".//input"));

How can I ask in xpath for "the div-tag that contains a span with the text 'hello world'"?

WebElement elem = driver.findElement(By.xpath("//div[span[text()='hello world']]"));

The XPath spec is a suprisingly good read on this.

You can explicitly enable escaping of Xml entities by using an attribute escapeXml value equals to true. FYI, it's by default "true".

Sure there is! For instance:

<xsl:if test="not(contains($hhref, '1234'))">
  <li>
    <a href="{$hhref}" title="{$pdate}">
      <xsl:value-of select="title"/>
    </a>
  </li>
</xsl:if>

The syntax is: contains(stringToSearchWithin, stringToSearchFor)

If it's your root module just add it to PYTHONPATH (PyCharm usually does that)

export PYTHONPATH=$PYTHONPATH:<root module path>

for Docker:

ENV PYTHONPATH="${PYTHONPATH}:<root module path in container>"

It's worth looking at Pydb, "an expanded version of the Python debugger loosely based on the gdb command set". It includes signal managers which can take care of starting the debugger when a specified signal is sent.

A 2006 Summer of Code project looked at adding remote-debugging features to pydb in a module called mpdb.

I was getting e.data.indexOf is not a function error, after debugging it, I found that it was actually a TypeError, which meant, indexOf() being a function is applicable to strings, so I typecasted the data like the following and then used the indexOf() method to make it work

e.data.toString().indexOf('<stringToBeMatchedToPosition>')

Not sure if my answer was accurate to the question, but yes shared my opinion as i faced a similar kind of situation.

UCanAccess is a pure Java JDBC driver that allows us to read from and write to Access databases without using ODBC. It uses two other packages, Jackcess and HSQLDB, to perform these tasks. The following is a brief overview of how to get it set up.

Option 1: Using Maven

If your project uses Maven you can simply include UCanAccess via the following coordinates:

groupId: net.sf.ucanaccess
artifactId: ucanaccess

The following is an excerpt from pom.xml, you may need to update the <version> to get the most recent release:

  <dependencies>
    <dependency>
        <groupId>net.sf.ucanaccess</groupId>
        <artifactId>ucanaccess</artifactId>
        <version>4.0.4</version>
    </dependency>
  </dependencies>

Option 2: Manually adding the JARs to your project

As mentioned above, UCanAccess requires Jackcess and HSQLDB. Jackcess in turn has its own dependencies. So to use UCanAccess you will need to include the following components:

UCanAccess (ucanaccess-x.x.x.jar)
HSQLDB (hsqldb.jar, version 2.2.5 or newer)
Jackcess (jackcess-2.x.x.jar)
commons-lang (commons-lang-2.6.jar, or newer 2.x version)
commons-logging (commons-logging-1.1.1.jar, or newer 1.x version)

Fortunately, UCanAccess includes all of the required JAR files in its distribution file. When you unzip it you will see something like

ucanaccess-4.0.1.jar  
  /lib/
    commons-lang-2.6.jar  
    commons-logging-1.1.1.jar  
    hsqldb.jar  
    jackcess-2.1.6.jar

All you need to do is add all five (5) JARs to your project.

NOTE: Do not add loader/ucanload.jar to your build path if you are adding the other five (5) JAR files. The UcanloadDriver class is only used in special circumstances and requires a different setup. See the related answer here for details.

Eclipse: Right-click the project in Package Explorer and choose Build Path > Configure Build Path.... Click the "Add External JARs..." button to add each of the five (5) JARs. When you are finished your Java Build Path should look something like this

NetBeans: Expand the tree view for your project, right-click the "Libraries" folder and choose "Add JAR/Folder...", then browse to the JAR file.

After adding all five (5) JAR files the "Libraries" folder should look something like this:

IntelliJ IDEA: Choose File > Project Structure... from the main menu. In the "Libraries" pane click the "Add" (+) button and add the five (5) JAR files. Once that is done the project should look something like this:

That's it!

Now "U Can Access" data in .accdb and .mdb files using code like this

// assumes...
//     import java.sql.*;
Connection conn=DriverManager.getConnection(
        "jdbc:ucanaccess://C:/__tmp/test/zzz.accdb");
Statement s = conn.createStatement();
ResultSet rs = s.executeQuery("SELECT [LastName] FROM [Clients]");
while (rs.next()) {
    System.out.println(rs.getString(1));
}

Disclosure

At the time of writing this Q&A I had no involvement in or affiliation with the UCanAccess project; I just used it. I have since become a contributor to the project.

It depends on your IDE or compiler.

Here is a list for Eclipse Galileo:

• all to suppress all warnings
• boxing to suppress warnings relative to boxing/unboxing operations
• cast to suppress warnings relative to cast operations
• dep-ann to suppress warnings relative to deprecated annotation
• deprecation to suppress warnings relative to deprecation
• fallthrough to suppress warnings relative to missing breaks in switch statements
• finally to suppress warnings relative to finally block that don’t return
• hiding to suppress warnings relative to locals that hide variable
• incomplete-switch to suppress warnings relative to missing entries in a switch statement (enum case)
• nls to suppress warnings relative to non-nls string literals
• null to suppress warnings relative to null analysis
• restriction to suppress warnings relative to usage of discouraged or forbidden references
• serial to suppress warnings relative to missing serialVersionUID field for a serializable class
• static-access to suppress warnings relative to incorrect static access
• synthetic-access to suppress warnings relative to unoptimized access from inner classes
• unchecked to suppress warnings relative to unchecked operations
• unqualified-field-access to suppress warnings relative to field access unqualified
• unused to suppress warnings relative to unused code

List for Indigo adds:

• javadoc to suppress warnings relative to javadoc warnings
• rawtypes to suppress warnings relative to usage of raw types
• static-method to suppress warnings relative to methods that could be declared as static
• super to suppress warnings relative to overriding a method without super invocations

List for Juno adds:

• resource to suppress warnings relative to usage of resources of type Closeable
• sync-override to suppress warnings because of missing synchronize when overriding a synchronized method

Kepler and Luna use the same token list as Juno (list).

Others will be similar but vary.

Expression you are looking for may be:

...
return any( isinstance(e, list) for e in my_list )

Testing:

>>> my_list = [1,2]
>>> any( isinstance(e, list) for e in my_list )
False
>>> my_list = [1,2, [3,4,5]]
>>> any( isinstance(e, list) for e in my_list )
True
>>> 

The problem with most solutions here is that they rewind the stack. This can be a big problem in some cases.In this example I show how to use iterators in different way to simulate real sleep

In this example the generator is calling it's own next() so once it's going, it's on his own.

var h=a();
h.next().value.r=h; //that's how U run it, best I came up with

//sleep without breaking stack !!!
function *a(){
    var obj= {};

    console.log("going to sleep....2s")

    setTimeout(function(){obj.r.next();},2000)  
     yield obj;

    console.log("woke up");
    console.log("going to sleep no 2....2s")
    setTimeout(function(){obj.r.next();},2000)  
     yield obj;

     console.log("woke up");
    console.log("going to sleep no 3....2s")

     setTimeout(function(){obj.r.next();},2000) 
     yield obj;

    console.log("done");

}

Option1:

Start the console and execute this:

db.version()

Option2:

Open a shell console and do:

$ mongod --version

It will show you something like

$ mongod --version
db version v3.0.2

You are using Python 2 for which the input() function tries to evaluate the expression entered. Because you enter a string, Python treats it as a name and tries to evaluate it. If there is no variable defined with that name you will get a NameError exception.

To fix the problem, in Python 2, you can use raw_input(). This returns the string entered by the user and does not attempt to evaluate it.

Note that if you were using Python 3, input() behaves the same as raw_input() does in Python 2.

Cause :

This issue is caused:

1- tomcat can't find the jvm file from the directory specified to start the service because is deleted.

2- Incorrect permissions to the java folder for read&write access

3- Incorrect JAVA_HOME path.

4- Antivirus deleted the jvm file from java folder

Resolution:

1- confirm that especified file exisit in the java directoy.

2- Make sure that file has read&write permissions.

3- Confirm that JAVA_HOME is correct for java version.

4- if file has been deleted reinstall same java version to recreate missing files.

You can check the return value from scanf. This code will just sit there until it receives a string.

int a;

do {
  // other code
  a = scanf("%s", url);

} while (a <= 0);

Use std::printf and c_str() example:

std::printf("Follow this command: %s", myString.c_str());

In addition to what has already been said about multiple and virtual inheritance(s), there is a very interesting article on Dr Dobb's Journal: Multiple Inheritance Considered Useful

Perhaps a 63.2% / 36.8% is a reasonable choice. The reason would be that if you had a total sample size n and wanted to randomly sample with replacement (a.k.a. re-sample, as in the statistical bootstrap) n cases out of the initial n, the probability of an individual case being selected in the re-sample would be approximately 0.632, provided that n is not too small, as explained here: https://stats.stackexchange.com/a/88993/16263

For a sample of n=250, the probability of an individual case being selected for a re-sample to 4 digits is 0.6329. For a sample of n=20000, the probability is 0.6321.

 this.requestWindowFeature(getWindow().FEATURE_NO_TITLE);

Solution:

value.replaceAll("[^A-Za-z0-9]", "")

Explanation:

[^abc] When a caret ^ appears as the first character inside square brackets, it negates the pattern. This pattern matches any character except a or b or c.

Looking at the keyword as two function:

• [(Pattern)] = match(Pattern)
• [^(Pattern)] = notMatch(Pattern)

Moreover regarding a pattern:

• A-Z = all characters included from A to Z

• a-z = all characters included from a to z

• 0=9 = all characters included from 0 to 9

Therefore it will substitute all the char NOT included in the pattern

Try this

var json = '{ "key1" : "watevr1", "key2" : "watevr2", "key3" : "watevr3" }';
json = $.parseJSON(json);

var i = 0, req_index = "";
$.each(json, function(index, value){
    if(index == 'key2'){
        req_index = i;
    }
    i++;
});
alert(req_index);

The basic colours are RGB not RYB. Yes most of the softwares use the traditional RGB which can be used to mix together to form any other color i.e. RGB are the fundamental colours (as defined in Physics & Chemistry texts).

The printer user CMYK (cyan, magenta, yellow, and black) coloring as said by @jcomeau_ictx. You can view the following article to know about RGB vs CMYK: RGB Vs CMYK

A bit more information from the extract about them:

Red, Green, and Blue are "additive colors". If we combine red, green and blue light you will get white light. This is the principal behind the T.V. set in your living room and the monitor you are staring at now. Additive color, or RGB mode, is optimized for display on computer monitors and peripherals, most notably scanning devices.

Cyan, Magenta and Yellow are "subtractive colors". If we print cyan, magenta and yellow inks on white paper, they absorb the light shining on the page. Since our eyes receive no reflected light from the paper, we perceive black... in a perfect world! The printing world operates in subtractive color, or CMYK mode.

A callback lets you pass executable code as an argument to other code. In C and C++ this is implemented as a function pointer. In .NET you would use a delegate to manage function pointers.

A few uses include error signaling and controlling whether a function acts or not.

A simple solution could be:

interface bar {

let bars: bar[];
bars = [];

UPDATE db.tablename SET columnID = (SELECT UUID()) where columnID is not null

You need to pass an array of element to jsx. The problem is that forEach does not return anything (i.e it returns undefined). So it's better to use map because map returns an array:

class QuestionSet extends Component {
render(){ 
    <div className="container">
       <h1>{this.props.question.text}</h1>
       {this.props.question.answers.map((answer, i) => {     
           console.log("Entered");                 
           // Return the element. Also pass key     
           return (<Answer key={answer} answer={answer} />) 
        })}
}

export default QuestionSet;

Try this :

   for match in re.finditer(r"\[P[^\]]*\](.*?)\[/P\]", subject):
        # match start: match.start()
        # match end (exclusive): match.end()
        # matched text: match.group()

Here is mine 1-liner

    def optArg(prefix: String) = args.drop(3).find { _.startsWith(prefix) }.map{_.replaceFirst(prefix, "")}
    def optSpecified(prefix: String) = optArg(prefix) != None
    def optInt(prefix: String, default: Int) = optArg(prefix).map(_.toInt).getOrElse(default)

It drops 3 mandatory arguments and gives out the options. Integers are specified like notorious -Xmx<size> java option, jointly with the prefix. You can parse binaries and integers as simple as

val cacheEnabled = optSpecified("cacheOff")
val memSize = optInt("-Xmx", 1000)

No need to import anything.

I just noticed that top is available in adb, so you can do things like

  adb shell
  top -m 5

to monitor the top five CPU hogging processes.

Or

  adb shell top -m 5 -s cpu -n 20 |tee top.log

to record this for one minute and collect the output to a file on your computer.

In my case, I was missing import UIKit on top of my NSManagedObject subclass. After importing it, I could remove that error as UIApplication is the part of UIKit

Hope it helps others !!!

If both arrays are in the correct order; where each item corresponds to its associated member identifier then you can simply use.

var merge = _.merge(arr1, arr2);

Which is the short version of:

var merge = _.chain(arr1).zip(arr2).map(function(item) {
    return _.merge.apply(null, item);
}).value();

Or, if the data in the arrays is not in any particular order, you can look up the associated item by the member value.

var merge = _.map(arr1, function(item) {
    return _.merge(item, _.find(arr2, { 'member' : item.member }));
});

You can easily convert this to a mixin. See the example below:

_.mixin({_x000D_
  'mergeByKey' : function(arr1, arr2, key) {_x000D_
    var criteria = {};_x000D_
    criteria[key] = null;_x000D_
    return _.map(arr1, function(item) {_x000D_
      criteria[key] = item[key];_x000D_
      return _.merge(item, _.find(arr2, criteria));_x000D_
    });_x000D_
  }_x000D_

This is equivalent to new Date().getTime() in JavaScript :

Use the below statement to get the time in seconds.

SELECT  cast(DATEDIFF(s, '1970-01-01 00:00:00.000', '2016-12-09 16:22:17.897' ) as bigint)

Use the below statement to get the time in milliseconds.

SELECT  cast(DATEDIFF(s, '1970-01-01 00:00:00.000', '2016-12-09 16:22:17.897' ) as bigint)  * 1000

The R-squared is not dependent on the number of variables in the model. The adjusted R-squared is.

The adjusted R-squared adds a penalty for adding variables to the model that are uncorrelated with the variable your trying to explain. You can use it to test if a variable is relevant to the thing your trying to explain.

Adjusted R-squared is R-squared with some divisions added to make it dependent on the number of variables in the model.

false == 0 and true = !false

i.e. anything that is not zero and can be converted to a boolean is not false, thus it must be true.

Some examples to clarify:

if(0)          // false
if(1)          // true
if(2)          // true
if(0 == false) // true
if(0 == true)  // false
if(1 == false) // false
if(1 == true)  // true
if(2 == false) // false
if(2 == true)  // false
cout << false  // 0
cout << true   // 1

true evaluates to 1, but any int that is not false (i.e. 0) evaluates to true but is not equal to true since it isn't equal to 1.

You were close. This will work:

.image { position: relative; border: 1px solid black; width: 200px; height: 200px; }
.image img { max-width: 100%; max-height: 100%; }
.overlay { position: absolute; top: 0; left: 0; right:0; bottom:0; display: none; background-color: rgba(0,0,0,0.5); }
.image:hover .overlay { display: block; }

You needed to put the :hover on image, and make the .overlay cover the whole image by adding right:0; and bottom:0.

With the Return statement from the proc, I needed to assign the temp variable and pass it to another stored procedure. The value was getting assigned fine but when passing it as a parameter, it lost the value. I had to create a temp table and set the variable from the table (SQL 2008)

From this: 
declare @anID int
exec @anID = dbo.StoredProc_Fetch @ID, @anotherID, @finalID
exec dbo.ADifferentStoredProc @anID (no value here)

To this:
declare @t table(id int) 
declare @anID int
insert into @t exec dbo.StoredProc_Fetch @ID, @anotherID, @finalID
set @anID= (select Top 1 * from @t)

The ID you are trying is an serverside.

That is going to render in the browser differently.

try to get the ID by watching the html in the Browser.

var TestVar = document.getElementById('ctl00_ContentColumn_txt_model_code').value;

this may works.

Or do that ClientID method. That also works but ultimately the browser will get the same thing what i had written.

$("#expires1").click(function(){
     if (this.checked)
        alert("testing....");
});

I wanted a splash screen that would display until the main program form was ready to be displayed, so timers etc were no use to me. I also wanted to keep it as simple as possible. My application starts with (abbreviated):

static void Main()
{
    Splash frmSplash = new Splash();
    frmSplash.Show();
    Application.Run(new ReportExplorer(frmSplash));
}

Then, ReportExplorer has the following:

public ReportExplorer(Splash frmSplash)
{
    this.frmSplash = frmSplash;
    InitializeComponent();
}

Finally, after all the initialisation is complete:

if (frmSplash != null) 
{
     frmSplash.Close();
     frmSplash = null;
}

Maybe I'm missing something, but this seems a lot easier than mucking about with threads and timers.

My problem was in the config.xml. Changing:

<access origin="*" launch-external="yes"/>

to

<access origin="*"/>

fixed it.

ipta = raw_input("Word: ") ## asks for input
words = [] ## creates list
unique_words = set(words)

This is from PasswordEncoder interface documentation from Spring Security,

 * @param rawPassword the raw password to encode and match
 * @param encodedPassword the encoded password from storage to compare with
 * @return true if the raw password, after encoding, matches the encoded password from
 * storage
 */
boolean matches(CharSequence rawPassword, String encodedPassword);

Which means, one will need to match rawPassword that user will enter again upon next login and matches it with Bcrypt encoded password that's stores in database during previous login/registration.

According to the official docu it's recommended to downgrade the whole Python environment:

conda install python=3.5

I just wrote a quick plugin to run a test using your same snippet and it works fine

$.fn.test = function() {
      return this.each(function(){
        var new_id = 5;
        $(this).attr('id',   this.id + '_' + new_id);
        $(this).attr('name', this.name + '_' + new_id);
        $(this).attr('value', 'test');
      });
    };

$(document).ready(function() {
    $('#field_id').test()
});

<body>
  <div id="container">

  <input type="text" name="field_name" id="field_id" value="meh" />
  </div>
</body>

So I can only presume something else is going on in your code. Can you provide some more details?

You just need to add an "A" record in the DNS manager on Godaddy. In that "A" record put your IP from dreamhost.

I know this works since I'm doing the very same thing.

Below is what worked for me:

1. In IIS Click on root note "LAPTOP ____**".
2. From option being shown in middle tray, Click on Configuration editor at bottom.
3. In Top Drop Down select "system.webServer/handlers".
4. At right window in Section Unlock Section.

Here's a custom IEnumerable<> extension method that can be used to loop through two lists simultaneously.

        }


    }

If it's any help to anyone, give permission to "IIS_IUSRS" group.

Note that if you can't find "IIS_IUSRS", try prepending it with your server's name, like "MySexyServer\IIS_IUSRS".

I'm not sure what you mean by a string that contains binary numbers. But for reversing a string (or any STL-compatible container), you can use std::reverse(). std::reverse() operates in place, so you may want to make a copy of the string first:

#include <algorithm>
#include <iostream>
#include <string>

int main()
{
    std::string foo("foo");
    std::string copy(foo);
    std::cout << foo << '\n' << copy << '\n';

    std::reverse(copy.begin(), copy.end());
    std::cout << foo << '\n' << copy << '\n';
}

Most of the answers suggest the Array.prototype.indexOf method, the only problem is that it will not work on any IE version before IE9.

As an alternative I leave you two more options that will work on all browsers:

if (/Foo|Bar|Baz/.test(str)) {
  // ...
}


if (str.match("Foo|Bar|Baz")) {
  // ...
}

import tensorflow as tf
sess = tf.Session()

this code will show an Attribute error on version 2.x

to use version 1.x code in version 2.x

try this

import tensorflow.compat.v1 as tf
sess = tf.Session()

Data-Binding

You go around making your webpage, and keep on putting {{data bindings}} whenever you feel you would have dynamic data. Angular will then provide you a $scope handler, which you can populate (statically or through calls to the web server).

This is a good understanding of data-binding. I think you've got that down.

DOM Manipulation

For simple DOM manipulation, which doesnot involve data manipulation (eg: color changes on mousehover, hiding/showing elements on click), jQuery or old-school js is sufficient and cleaner. This assumes that the model in angular's mvc is anything that reflects data on the page, and hence, css properties like color, display/hide, etc changes dont affect the model.

I can see your point here about "simple" DOM manipulation being cleaner, but only rarely and it would have to be really "simple". I think DOM manipulation is one the areas, just like data-binding, where Angular really shines. Understanding this will also help you see how Angular considers its views.

I'll start by comparing the Angular way with a vanilla js approach to DOM manipulation. Traditionally, we think of HTML as not "doing" anything and write it as such. So, inline js, like "onclick", etc are bad practice because they put the "doing" in the context of HTML, which doesn't "do". Angular flips that concept on its head. As you're writing your view, you think of HTML as being able to "do" lots of things. This capability is abstracted away in angular directives, but if they already exist or you have written them, you don't have to consider "how" it is done, you just use the power made available to you in this "augmented" HTML that angular allows you to use. This also means that ALL of your view logic is truly contained in the view, not in your javascript files. Again, the reasoning is that the directives written in your javascript files could be considered to be increasing the capability of HTML, so you let the DOM worry about manipulating itself (so to speak). I'll demonstrate with a simple example.

This is the markup we want to use. I gave it an intuitive name.

<div rotate-on-click="45"></div>

First, I'd just like to comment that if we've given our HTML this functionality via a custom Angular Directive, we're already done. That's a breath of fresh air. More on that in a moment.

Implementation with jQuery

live demo here (click).

function rotate(deg, elem) {
  $(elem).css({
    webkitTransform: 'rotate('+deg+'deg)', 
    mozTransform: 'rotate('+deg+'deg)', 
    msTransform: 'rotate('+deg+'deg)', 
    oTransform: 'rotate('+deg+'deg)', 
    transform: 'rotate('+deg+'deg)'    
  });
}

function addRotateOnClick($elems) {
  $elems.each(function(i, elem) {
    var deg = 0;
    $(elem).click(function() {
      deg+= parseInt($(this).attr('rotate-on-click'), 10);
      rotate(deg, this);
    });
  });
}

addRotateOnClick($('[rotate-on-click]'));

Implementation with Angular

live demo here (click).

app.directive('rotateOnClick', function() {
  return {
    restrict: 'A',
    link: function(scope, element, attrs) {
      var deg = 0;
      element.bind('click', function() {
        deg+= parseInt(attrs.rotateOnClick, 10);
        element.css({
          webkitTransform: 'rotate('+deg+'deg)', 
          mozTransform: 'rotate('+deg+'deg)', 
          msTransform: 'rotate('+deg+'deg)', 
          oTransform: 'rotate('+deg+'deg)', 
          transform: 'rotate('+deg+'deg)'    
        });
      });
    }
  };
});

Pretty light, VERY clean and that's just a simple manipulation! In my opinion, the angular approach wins in all regards, especially how the functionality is abstracted away and the dom manipulation is declared in the DOM. The functionality is hooked onto the element via an html attribute, so there is no need to query the DOM via a selector, and we've got two nice closures - one closure for the directive factory where variables are shared across all usages of the directive, and one closure for each usage of the directive in the link function (or compile function).

Two-way data binding and directives for DOM manipulation are only the start of what makes Angular awesome. Angular promotes all code being modular, reusable, and easily testable and also includes a single-page app routing system. It is important to note that jQuery is a library of commonly needed convenience/cross-browser methods, but Angular is a full featured framework for creating single page apps. The angular script actually includes its own "lite" version of jQuery so that some of the most essential methods are available. Therefore, you could argue that using Angular IS using jQuery (lightly), but Angular provides much more "magic" to help you in the process of creating apps.

This is a great post for more related information: How do I “think in AngularJS” if I have a jQuery background?

General differences.

The above points are aimed at the OP's specific concerns. I'll also give an overview of the other important differences. I suggest doing additional reading about each topic as well.

Angular and jQuery can't reasonably be compared.

Angular is a framework, jQuery is a library. Frameworks have their place and libraries have their place. However, there is no question that a good framework has more power in writing an application than a library. That's exactly the point of a framework. You're welcome to write your code in plain JS, or you can add in a library of common functions, or you can add a framework to drastically reduce the code you need to accomplish most things. Therefore, a more appropriate question is:

Why use a framework?

Good frameworks can help architect your code so that it is modular (therefore reusable), DRY, readable, performant and secure. jQuery is not a framework, so it doesn't help in these regards. We've all seen the typical walls of jQuery spaghetti code. This isn't jQuery's fault - it's the fault of developers that don't know how to architect code. However, if the devs did know how to architect code, they would end up writing some kind of minimal "framework" to provide the foundation (achitecture, etc) I discussed a moment ago, or they would add something in. For example, you might add RequireJS to act as part of your framework for writing good code.

Here are some things that modern frameworks are providing:

• Templating
• Data-binding
• routing (single page app)
• clean, modular, reusable architecture
• security
• additional functions/features for convenience

Before I further discuss Angular, I'd like to point out that Angular isn't the only one of its kind. Durandal, for example, is a framework built on top of jQuery, Knockout, and RequireJS. Again, jQuery cannot, by itself, provide what Knockout, RequireJS, and the whole framework built on top them can. It's just not comparable.

If you need to destroy a planet and you have a Death Star, use the Death star.

Angular (revisited).

Building on my previous points about what frameworks provide, I'd like to commend the way that Angular provides them and try to clarify why this is matter of factually superior to jQuery alone.

DOM reference.

In my above example, it is just absolutely unavoidable that jQuery has to hook onto the DOM in order to provide functionality. That means that the view (html) is concerned about functionality (because it is labeled with some kind of identifier - like "image slider") and JavaScript is concerned about providing that functionality. Angular eliminates that concept via abstraction. Properly written code with Angular means that the view is able to declare its own behavior. If I want to display a clock:

<clock></clock>

Done.

Yes, we need to go to JavaScript to make that mean something, but we're doing this in the opposite way of the jQuery approach. Our Angular directive (which is in it's own little world) has "augumented" the html and the html hooks the functionality into itself.

MVW Architecure / Modules / Dependency Injection

Angular gives you a straightforward way to structure your code. View things belong in the view (html), augmented view functionality belongs in directives, other logic (like ajax calls) and functions belong in services, and the connection of services and logic to the view belongs in controllers. There are some other angular components as well that help deal with configuration and modification of services, etc. Any functionality you create is automatically available anywhere you need it via the Injector subsystem which takes care of Dependency Injection throughout the application. When writing an application (module), I break it up into other reusable modules, each with their own reusable components, and then include them in the bigger project. Once you solve a problem with Angular, you've automatically solved it in a way that is useful and structured for reuse in the future and easily included in the next project. A HUGE bonus to all of this is that your code will be much easier to test.

It isn't easy to make things "work" in Angular.

THANK GOODNESS. The aforementioned jQuery spaghetti code resulted from a dev that made something "work" and then moved on. You can write bad Angular code, but it's much more difficult to do so, because Angular will fight you about it. This means that you have to take advantage (at least somewhat) to the clean architecture it provides. In other words, it's harder to write bad code with Angular, but more convenient to write clean code.

Angular is far from perfect. The web development world is always growing and changing and there are new and better ways being put forth to solve problems. Facebook's React and Flux, for example, have some great advantages over Angular, but come with their own drawbacks. Nothing's perfect, but Angular has been and is still awesome for now. Just as jQuery once helped the web world move forward, so has Angular, and so will many to come.

The accepted answer works perfectly fine. I just want to mention a minor problem with the answer devXen has given.

If you set the icon like this:

<link rel="shortcut icon" type="image/x-icon" href="icon.ico">

The icon will work as expected:

However, if you set it like devXen has suggested:

<title> Amir A. Shabani</title>

The title of the page moves upon refresh:

So I would advise using <link> instead.

Without having to have another batch file to pass arguments to (and use the argument operators), you can use FOR /F:

FOR /F %%i IN ("..\relativePath") DO echo absolute path: %%~fi

where the i in %%~fi is the variable defined at /F %%i. eg. if you changed that to /F %%a then the last part would be %%~fa.

To do the same thing right at the command prompt (and not in a batch file) replace %% with %...

my telepathic abilities are not particularly great, but here is what I think you want:

def merge(list_of_strings, indices):
    list_of_strings[indices[0]] = ''.join(list_of_strings[i] for i in indices)
    list_of_strings = [s for i, s in enumerate(list_of_strings) if i not in indices[1:]]
    return list_of_strings

I should note, since it might be not obvious, that it's not the same as what is proposed in other answers.

If, like me, you are trying to use GETDATE() within an expression and have the seemingly unreasonable requirement (SSIS/SSDT seems very much a work in progress to me, and not a polished offering) of wanting that date to get inserted into SQL Server as a valid date (type = datetime), then I found this expression to work:

@[User::someVar] = (DT_WSTR,4)YEAR(GETDATE()) + "-"  + RIGHT("0" + (DT_WSTR,2)MONTH(GETDATE()), 2) + "-"  + RIGHT("0" + (DT_WSTR,2)DAY( GETDATE()), 2) + " " + RIGHT("0" + (DT_WSTR,2)DATEPART("hh", GETDATE()), 2) + ":" + RIGHT("0" + (DT_WSTR,2)DATEPART("mi", GETDATE()), 2) + ":" + RIGHT("0" + (DT_WSTR,2)DATEPART("ss", GETDATE()), 2)

I found this code snippet HERE

=SUMPRODUCT( (MONTH($A$2:$A$6)=1) * ($B$2:$B$6) )

Explanation:

• (MONTH($A$2:$A$6)=1) creates an array of 1 and 0, it's 1 when the month is january, thus in your example the returned array would be [1, 1, 1, 0, 0]

• SUMPRODUCT first multiplies each value of the array created in the above step with values of the array ($B$2:$B$6), then it sums them. Hence in your example it does this: (1 * 430) + (1 * 96) + (1 * 440) + (0 * 72.10) + (0 * 72.30)

This works also in OpenOffice and Google Spreadsheets

In commandline, there is a command dropuser available to do drop user from postgres.

$ dropuser someuser

Be Careful , Perhaps , you have a class and a subclass .

  <div id='id' class='myclass mysubclass' >dfdfdfsdfds</div>

If you use previous solutions , you will have :

myclass mysubclass

So if you want to have the class selector, do the following :

var className = '.'+$('#id').attr('class').split(' ').join('.')

and you will have

.myclass.mysubclass

Now if you want to select all elements that have the same class such as div above :

   var brothers=$('.'+$('#id').attr('class').split(' ').join('.'))

that means

var brothers=$('.myclass.mysubclass')

Update 2018

OR can be implemented with vanilla javascript in 2 lines:

  const { classList } = document.querySelector('#id');
  document.querySelectorAll(`.${Array.from(classList).join('.')}`);

You haven't properly cased your onchange prop in the input. It needs to be onChange in JSX.

<input
  type="text"
  value={this.props.searchString}
  ref="searchStringInput"
  onchange={this.handleChange} <--[should be onChange]
/>  

The topic of passing a value prop to an <input>, and then somehow changing the value passed in response to user interaction using an onChange handler is pretty well-considered in the docs.

They refer to such inputs as Controlled Components, and refer to inputs that instead let the DOM natively handle the input's value and subsequent changes from the user as Uncontrolled Components.

Whenever you set the value prop of an input to some variable, you have a Controlled Component. This means you must change the value of the variable by some programmatic means or else the input will always hold that value and will never change, even when you type -- the native behaviour of the input, to update its value on typing, is overridden by React here.

So, you're correctly taking that variable from state, and have a handler to update the state all set up fine. The problem was because you have onchange and not the correct onChange the handler was never being called and so the value was never being updated when you type into the input. When you do use onChange the handler is called, the value is updated when you type, and you see your changes.

Define a class like this :

public class myclass {
       string id ;
       string title ;
       string content;
 }

 public class program {
        public void Main () {
               List<myclass> objlist = new List<myclass> () ;
               foreach (var value in objlist)  {
                       TextBox1.Text = value.id ;
                       TextBox2.Text= value.title;
                       TextBox3.Text= value.content ;
                }
         }
  }

I tried to draw a sketch and you can improve it in many ways. Instead of defining class "myclass", you can define struct.

Starting with Node.js version 13 you can take advantage of ES6 Modules.

export function foo() {
    return 'foo';
}

export function bar() {
    return foo();
}

Following the Class approach:

class MyClass {

    foo() {
        return 'foo';
    }

    bar() {
        return this.foo();
    }
}

module.exports = new MyClass();

This will instantiate the class only once, due to Node's module caching:
https://nodejs.org/api/modules.html#modules_caching

1 IDs are meant to be unique

2 You dont need to pass any argument as you can call them in your javascript

<form>
  a: <input type="number" name="a" id="a"><br>
  b: <input type="number" name="b" id="b"><br>
  <button onclick="add()">Add</button>
</form>
<script>
  function add() {
    var a = document.getElementById('a').value;
    var b = document.getElementById('b').value;
    var sum = a + b;
    alert(sum);
  }
</script>

This depends upon scenarios.

Let's say you have some business functionality and you need to process something with that value further but having null value at time of processing would impact it.

Then, in that case, you can use Optional<?>.

String nullName = null;

String name = Optional.ofNullable(nullName)
                      .map(<doSomething>)
                      .orElse("Default value in case of null");

You're pretty close:

var myTag = $(':selected', element).attr("myTag");

partition() may be better then split() for this purpose as it has the better predicable results for situations you have no delimiter or more delimiters.

Chain both class selectors (without a space in between):

.foo.bar {
    /* Styles for element(s) with foo AND bar classes */
}

If you still have to deal with ancient browsers like IE6, be aware that it doesn't read chained class selectors correctly: it'll only read the last class selector (.bar in this case) instead, regardless of what other classes you list.

To illustrate how other browsers and IE6 interpret this, consider this CSS:

* {
    color: black;
}

.foo.bar {
    color: red;
}

Output on supported browsers is:

<div class="foo">Hello Foo</div>       <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div>       <!-- Not selected, black text [3] -->

Output on IE6 is:

<div class="foo">Hello Foo</div>       <!-- Not selected, black text [1] -->
<div class="foo bar">Hello World</div> <!-- Selected, red text [2] -->
<div class="bar">Hello Bar</div>       <!-- Selected, red text [2] -->

Footnotes:

• Supported browsers:
  1. Not selected as this element only has class foo.
  2. Selected as this element has both classes foo and bar.
  3. Not selected as this element only has class bar.
     
     
• IE6:
  1. Not selected as this element doesn't have class bar.
  2. Selected as this element has class bar, regardless of any other classes listed.

There's no "else if". You have the following:

if (condition)
    statement or block

Or:

if (condition)
    statement or block
else
    statement or block

In the first case, the statement or block is executed if the condition is true (different than 0). In the second case, if the condition is true, the first statement or block is executed, otherwise the second statement or block is executed.

So, when you write "else if", that's an "else statement", where the second statement is an if statement. You might have problems if you try to do this:

if (condition)
    if (condition)
        statement or block
else
    statement or block

The problem here being you want the "else" to refer to the first "if", but you are actually referring to the second one. You fix this by doing:

if (condition)
{
    if (condition)
        statement or block
} else
    statement or block

To Understand the difference, one needs to to understand that "the godfather" paradigm of both procedural and functional programming is the imperative programming.

Basically procedural programming is merely a way of structuring imperative programs in which the primary method of abstraction is the "procedure." (or "function" in some programming languages). Even Object Oriented Programming is just another way of structuring an imperative program, where the state is encapsulated in objects, becoming an object with a "current state," plus this object has a set of functions, methods, and other stuff that let you the programmer manipulate or update the state.

Now, in regards to functional programming, the gist in its approach is that it identifies what values to take and how these values should be transferred. (so there is no state, and no mutable data as it takes functions as first class values and pass them as parameters to other functions).

PS: understanding every programming paradigm is used for should clarify the differences between all of them.

PSS: In the end of the day, programming paradigms are just different approaches to solving problems.

PSS: this quora answer has a great explanation.

Use the INTERVAL type to it. E.g:

--yesterday
SELECT NOW() - INTERVAL '1 DAY';

--Unrelated to the question, but PostgreSQL also supports some shortcuts:
SELECT 'yesterday'::TIMESTAMP, 'tomorrow'::TIMESTAMP, 'allballs'::TIME;

Then you can do the following on your query:

SELECT 
    org_id,
    count(accounts) AS COUNT,
    ((date_at) - INTERVAL '1 DAY') AS dateat
FROM 
    sourcetable
WHERE 
    date_at <= now() - INTERVAL '130 DAYS'
GROUP BY 
    org_id,
    dateat;

TIPS

Tip 1

You can append multiple operands. E.g.: how to get last day of current month?

SELECT date_trunc('MONTH', CURRENT_DATE) + INTERVAL '1 MONTH - 1 DAY';

Tip 2

You can also create an interval using make_interval function, useful when you need to create it at runtime (not using literals):

SELECT make_interval(days => 10 + 2);
SELECT make_interval(days => 1, hours => 2);
SELECT make_interval(0, 1, 0, 5, 0, 0, 0.0);

I simply wasn't linking the libraries in the "Link Binary with Libraries" section.

you can use ES6 back quits

  var inputs = [_x000D_
        `<input type='checkbox' id='chbox0' onclick='checkboxChecked(this);'> <input  type='text' class='noteinputs0'id='note` + 0 + `' placeholder='task0'><button  id='notebtn0'                     >creat</button>`, `<input type='text' class='noteinputs' id='note` + 1 + `' placeholder='task1'><button  class='notebuttons' id='notebtn1' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 2 + `' placeholder='task2'><button  class='notebuttons' id='notebtn2' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 3 + `' placeholder='task3'><button  class='notebuttons' id='notebtn3' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 4 + `' placeholder='task4'><button  class='notebuttons' id='notebtn4' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 5 + `' placeholder='task5'><button  class='notebuttons' id='notebtn5' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 6 + `' placeholder='task6'><button  class='notebuttons' id='notebtn6' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 7 + `' placeholder='task7'><button  class='notebuttons' id='notebtn7' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 8 + `' placeholder='task8'><button  class='notebuttons' id='notebtn8' >creat</button>`, `<input type='text' class='noteinputs' id='note` + 9 + `' placeholder='task9'><button  class='notebuttons' id='notebtn9' >creat</button>`_x000D_

Using reflection, this is the function i use :

public static bool doesPropertyExist(dynamic obj, string property)
{
    return ((Type)obj.GetType()).GetProperties().Where(p => p.Name.Equals(property)).Any();
}

then..

if (doesPropertyExist(myDynamicObject, "myProperty")){
    // ...
}

This is an Oracle-specific notation for an outer join. It means that it will include all rows from t1, and use NULLS in the t0 columns if there is no corresponding row in t0.

In standard SQL one would write:

SELECT t0.foo, t1.bar
  FROM FIRST_TABLE t0
 RIGHT OUTER JOIN SECOND_TABLE t1;

Oracle recommends not to use those joins anymore if your version supports ANSI joins (LEFT/RIGHT JOIN) :

Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions […]

Significant practical difference:

var str = 'hello word';

str instanceof String   // false

typeof str === 'string' // true

Don't ask me why.

There are two ways to achieve this:

final PageRequest page1 = new PageRequest(
  0, 20, Direction.ASC, "lastName", "salary"
);

final PageRequest page2 = new PageRequest(
  0, 20, new Sort(
    new Order(Direction.ASC, "lastName"), 
    new Order(Direction.DESC, "salary")
  )
);

dao.findAll(page1);

As you can see the second form is more flexible as it allows to define different direction for every property (lastName ASC, salary DESC).

process.terminate() doesn't work when using shell=True. This answer will help you.

You can use varStatus in your c:forEach loop

In your first example you can get the counter to work properly as follows...

<c:forEach var="tableEntity" items='${requestScope.tables}'>
   <c:forEach var="rowEntity" items='${tableEntity.rows}' varStatus="count">            
        my count is ${count.count}
    </c:forEach>
</c:forEach>

If you launch your program with -enableassertions (or -ea for short) then this statement

assert cond;

is equivalent to

if (!cond)
    throw new AssertionError();

If you launch your program without this option, the assert statement will have no effect.

For example, assert d >= 0 && d <= s.length();, as posted in your question, is equivalent to

if (!(d >= 0 && d <= s.length()))
    throw new AssertionError();

(If you launched with -enableassertions that is.)

Formally, the Java Language Specification: 14.10. The assert Statement says the following:

14.10. The assert Statement
An assertion is an assert statement containing a boolean expression. An assertion is either enabled or disabled. If the assertion is enabled, execution of the assertion causes evaluation of the boolean expression and an error is reported if the expression evaluates to false. If the assertion is disabled, execution of the assertion has no effect whatsoever.

Where "enabled or disabled" is controlled with the -ea switch and "An error is reported" means that an AssertionError is thrown.

And finally, a lesser known feature of assert:

You can append : "Error message" like this:

assert d != null : "d is null";

to specify what the error message of the thrown AssertionError should be.

There are other ways to parse it rather than the first answer. To parse it:

(1) If you want to grab information about date and time, you can parse it to a ZonedDatetime(since Java 8) or Date(old) object:

// ZonedDateTime's default format requires a zone ID(like [Australia/Sydney]) in the end.
// Here, we provide a format which can parse the string correctly.
DateTimeFormatter dtf = DateTimeFormatter.ISO_DATE_TIME;
ZonedDateTime zdt = ZonedDateTime.parse("2011-08-12T20:17:46.384Z", dtf);

or

// 'T' is a literal.
// 'X' is ISO Zone Offset[like +01, -08]; For UTC, it is interpreted as 'Z'(Zero) literal.
String pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSX";

// since no built-in format, we provides pattern directly.
DateFormat df = new SimpleDateFormat(pattern);

Date myDate = df.parse("2011-08-12T20:17:46.384Z");

(2) If you don't care the date and time and just want to treat the information as a moment in nanoseconds, then you can use Instant:

// The ISO format without zone ID is Instant's default.
// There is no need to pass any format.
Instant ins = Instant.parse("2011-08-12T20:17:46.384Z");

All of the javascript functions given here won't work for an xml document having unspecified white spaces between the end tag '>' and the start tag '<'. To fix them, you just need to replace the first line in the functions

var reg = /(>)(<)(\/*)/g;

by

var reg = /(>)\s*(<)(\/*)/g;

Not an expert on encoding, but after reading these...

• http://blogs.msdn.com/b/powershell/archive/2006/12/11/outputencoding-to-the-rescue.aspx
• http://technet.microsoft.com/en-us/library/hh847796.aspx
• http://www.johndcook.com/blog/2008/08/25/powershell-output-redirection-unicode-or-ascii/

... it seems fairly clear that the $OutputEncoding variable only affects data piped to native applications.

If sending to a file from withing PowerShell, the encoding can be controlled by the -encoding parameter on the out-file cmdlet e.g.

write-output "hello" | out-file "enctest.txt" -encoding utf8

Nothing else you can do on the PowerShell front then, but the following post may well help you:.

I assume you're seeing this in a React component's render method, like this (edit: your edited question does indeed show that):

class Example extends React.Component {_x000D_
  render() {_x000D_
    return <div>_x000D_
      <div>Children ({this.props.children.length}):</div>_x000D_
      {this.props.children}_x000D_
    </div>;_x000D_
  }_x000D_
}_x000D_
_x000D_
class Widget extends React.Component {_x000D_

  }_x000D_

children is a special property of React components which contains any child elements defined within the component, e.g. the divs inside Example above. {this.props.children} includes those children in the rendered result.

...what are the situations to use the same

You'd do it when you want to include the child elements in the rendered output directly, unchanged; and not if you didn't.

I think the documentation is reasonably helpful!

If you read it again, it says that adding open graph elements on your website will make your website act as a facebook page and you'll get the ability to publish updates to them etc.

So I think it's up to you - you can either just have a page with no OG elements, which is less work but also less 'rewarding' for you.

If you do use og, then set type to: blog

Finally: fb:admins or fb:app_id - A comma-separated list of either the Facebook IDs of page administrators or a Facebook Platform application ID. At a minimum, include only your own Facebook ID.

So just put your own fbid in there. As a tip, you can easily get this by looking at the url of your profile photo on facebook.

The MaxAge of -1 signals that you want the cookie to persist for the duration of the session. You want to set MaxAge to 0 instead.

From the API documentation:

A negative value means that the cookie is not stored persistently and will be deleted when the Web browser exits. A zero value causes the cookie to be deleted.

I don't think that notation is available because—unlike say PHP or C—everything in Ruby is an object.

Sure you could use $var=0; $var++ in PHP, but that's because it's a variable and not an object. Therefore, $var = new stdClass(); $var++ would probably throw an error.

I'm not a Ruby or RoR programmer, so I'm sure someone can verify the above or rectify it if it's inaccurate.

You can give like this....

<a href="@(IsProduction.IsProductionUrl)Index/LogOut">

A connect failed: ECONNREFUSED (Connection refused) most likely means that there is nothing listening on that port AND that IP address. Possible explanations include:

• the service has crashed or hasn't been (successfully!) started,
• your client is trying to connect using the wrong IP address or port,
• your client is trying to connect using a DNS name that resolves to the wrong IP, or
• server access is being blocked by a firewall that is "refusing" on the server/service's behalf. This is pretty unlikely given that normal practice (these days) is for firewalls to "blackhole" all unwanted connection attempts.

Note that while you have an array variable called urls, it cannot contain real URLs. There is no overload of the Socket constructor that takes a real URL in any form. Indeed, if you supplied a URL in string form like this:

 new Socket("http://example.com", 42)

the result would be a different exception. Likewise, if you attempt to connect to an IP address on a network that you can't route to (e.g. "a different WiFi network"), then you will get a different exception; e.g. "host not found", "no route to host" or "no route to network".

print then.date()

What you want is a datetime.date object. What you have is a datetime.datetime object. You can either change the object when you print as per above, or do the following when creating the object:

then = datetime.datetime.strptime(when, '%Y-%m-%d').date()

I've been working in C#/Razor and since I don't have IIS setup on my home laptop I looked for a javascript solution to load in views while creating static markup for our project.

I stumbled upon a website explaining methods of "ditching jquery," it demonstrates a method on the site does exactly what you're after in plain Jane javascript (reference link at the bottom of post). Be sure to investigate any security vulnerabilities and compatibility issues if you intend to use this in production. I am not, so I never looked into it myself.

JS Function

var getURL = function (url, success, error) {
    if (!window.XMLHttpRequest) return;
    var request = new XMLHttpRequest();
    request.onreadystatechange = function () {
        if (request.readyState === 4) {
            if (request.status !== 200) {
                if (error && typeof error === 'function') {
                    error(request.responseText, request);
                }
                return;
            }
            if (success && typeof success === 'function') {
                success(request.responseText, request);
            }
        }
    };
    request.open('GET', url);
    request.send();
};

Get the content

getURL(
    '/views/header.html',
    function (data) {
        var el = document.createElement(el);
        el.innerHTML = data;
        var fetch = el.querySelector('#new-header');
        var embed = document.querySelector('#header');
        if (!fetch || !embed) return;
        embed.innerHTML = fetch.innerHTML;

    }
);

<!-- This element will be replaced with #new-header -->
<div id="header"></div>

<!-- This element will replace #header -->
<header id="new-header"></header>

If this happens to you on mac (as it did to me):

1. Save the file as CSV (MS-DOS Comma-Separated)

2. Run the following script

   with open(csv_filename, 'rU') as csvfile:
       csvreader = csv.reader(csvfile)
       for row in csvreader:
           print ', '.join(row)
   

Check for package-lock.json file at C:\Windows\system32.

If it doesn't exist, run cmd as admin and execute the following commands:

Set EXPO_DEBUG=true
npm config set package-lock false
npm install

I had the same problem. My path back to default was as follows:

1. Install Eclipse Color Themes Plugin (http://www.eclipsecolorthemes.org/)
2. Navigate to Window->Preferences
3. Navigate to General->Appearance->Color Themes
4. Click Restore Defaults, then click Apply

That should take care of it.

To read multiple sheets from a workbook, use readxl package as follows:

library(readxl)
library(dplyr)

final_dataFrame <- bind_rows(path_to_workbook %>%
                              excel_sheets() %>%
                              set_names() %>%
                              map(read_excel, path = path_to_workbook))

Here, bind_rows (dplyr) will put all data rows from all sheets into one data frame, and path_to_workbook is the location of your data: "dir/of/the/data/workbook".

In Visual Studio you can use nuget to download the latest version. Just right click on the project and click 'Manage NuGet Packages' then search online for MySql.Data and install.

The following tested working

<iframe style="width:100%; height:100%;position:absolute;top:0px;left:0px;right:0px;bottom:0px" src="index.html" frameborder="0" height="100%" width="100%"></iframe>

If the result of, 'searchResult.Properties [ "user" ] [ 0 ]', is a string:

if ( ( searchResult.Properties [ "user" ].Count > 0 ) ) {

   profile.User = System.Text.Encoding.UTF8.GetString ( searchResult.Properties [ "user" ] [ 0 ].ToCharArray ().Select ( character => ( byte ) character ).ToArray () );

}

The key point being that converting a string to a byte [] can be done using LINQ:

.ToCharArray ().Select ( character => ( byte ) character ).ToArray () )

And the inverse:

.Select ( character => ( char ) character ).ToArray () )

df.isna() return True values for NaN, False for the rest. So, doing:

df.isna().any()

will return True for any column having a NaN, False for the rest

You're not suppose to test private methods. Only non-private methods needs to be tested as these should call the private methods anyway. If you "want" to test private methods, it may indicate that you need to rethink your design:

Am I using proper dependency injection? Do I possibly needs to move the private methods into a separate class and rather test that? Must these methods be private? ...can't they be default or protected rather?

In the above instance, the two methods that are called "randomly" may actually need to be placed in a class of their own, tested and then injected into the class above.

As other answers have stated, the -> symbol is used as part of function annotations. In more recent versions of Python >= 3.5, though, it has a defined meaning.

PEP 3107 -- Function Annotations described the specification, defining the grammar changes, the existence of func.__annotations__ in which they are stored and, the fact that it's use case is still open.

In Python 3.5 though, PEP 484 -- Type Hints attaches a single meaning to this: -> is used to indicate the type that the function returns. It also seems like this will be enforced in future versions as described in What about existing uses of annotations:

The fastest conceivable scheme would introduce silent deprecation of non-type-hint annotations in 3.6, full deprecation in 3.7, and declare type hints as the only allowed use of annotations in Python 3.8.

^{(Emphasis mine)}

This hasn't been actually implemented as of 3.6 as far as I can tell so it might get bumped to future versions.

According to this, the example you've supplied:

def f(x) -> 123:
    return x

will be forbidden in the future (and in current versions will be confusing), it would need to be changed to:

def f(x) -> int:
    return x

for it to effectively describe that function f returns an object of type int.

The annotations are not used in any way by Python itself, it pretty much populates and ignores them. It's up to 3rd party libraries to work with them.

+1 on James A. Rosen's suggested solution as it has worked well for me, however for completists this site is a fascinating read and the best attempt I've seen in documenting addresses worldwide: http://www.columbia.edu/kermit/postal.html

If you are using Oracle, consider specifying cache size for the sequence. If you are routinely create objects in batches of 5K, you can just set it to a 1000 or 5000. We did it for the sequence used for the surrogate primary key and were amazed that execution times for an ETL process hand-written in Java dropped in half.

I could not paste formatted code into comment. Here's the sequence DDL:

create sequence seq_mytable_sid 
minvalue 1 
maxvalue 999999999999999999999999999 
increment by 1 
start with 1 
cache 1000 
order  
nocycle;

As the best anwser have writed using XMLHttpResponse except window.open, and I make the abstracts-anwser as a instance.

The main Js file is download.js Download-JS

If you don't care about any local changes (including untracked or generated files or subrepositories which just happen to be here) and just want a copy from the repo:

git reset --hard HEAD
git clean -xffd
git pull

Again, this will nuke any changes you've made locally so use carefully. Think about rm -Rf when doing this.

I've tried all the approaches, and this one is the simplest for me because I'm using IWebBrowser2 and don't have 10 browsers to contend with:

document.onselectstart = new Function('return false;');

Works perfectly for me!

Make sure your Activity extends FragmentActivity.

If you are using Matplotlib and are trying to get good figures in a LaTeX document, save as an EPS. Specifically, try something like this after running the commands to plot the image:

plt.savefig('destination_path.eps', format='eps')

I have found that EPS files work best and the dpi parameter is what really makes them look good in a document.

To specify the orientation of the figure before saving, simply call the following before the plt.savefig call, but after creating the plot (assuming you have plotted using an axes with the name ax):

ax.view_init(elev=elevation_angle, azim=azimuthal_angle)

Where elevation_angle is a number (in degrees) specifying the polar angle (down from vertical z axis) and the azimuthal_angle specifies the azimuthal angle (around the z axis).

I find that it is easiest to determine these values by first plotting the image and then rotating it and watching the current values of the angles appear towards the bottom of the window just below the actual plot. Keep in mind that the x, y, z, positions appear by default, but they are replaced with the two angles when you start to click+drag+rotate the image.

Yes, It's possible with DOUBLE STASH

1. Stage all your files that you need to stash.
2. Run git stash --keep-index. This command will create a stash with ALL of your changes (staged and unstaged), but will leave the staged changes in your working directory (still in state staged).
3. Run git stash push -m "good stash"
4. Now your "good stash" has ONLY staged files.

Now if you need unstaged files before stash, simply apply first stash (the one created with --keep-index) and now you can remove files you stashed to "good stash".

Enjoy

I had to do this for a project. What I ended up doing was start a separate thread for the function

t = threading.Thread(target =heartbeat, args=(worker,))
t.start()

****heartbeat is my function, worker is one of my arguments****

inside of my heartbeat function:

def heartbeat(worker):

    while True:
        time.sleep(5)
        #all of my code

So when I start the thread the function will repeatedly wait 5 seconds, run all of my code, and do that indefinitely. If you want to kill the process just kill the thread.

Caveats

Here are two worthy caveats from the comments.

Either you want user to be of type User | {} or Partial<User>, or you need to redefine the User type to allow an empty object. Right now, the compiler is correctly telling you that user is not a User. – jcalz

I don't think this should be considered a proper answer because it creates an inconsistent instance of the type, undermining the whole purpose of TypeScript. In this example, the property Username is left undefined, while the type annotation is saying it can't be undefined. – Ian Liu Rodrigues

Answer

One of the design goals of TypeScript is to "strike a balance between correctness and productivity." If it will be productive for you to do this, use Type Assertions to create empty objects for typed variables.

type User = {
    Username: string;
    Email: string;
}

const user01 = {} as User;
const user02 = <User>{};

user01.Email = "[email protected]";

Here is a working example for you.

Try Modulo:

5.55%1 = 0.54999999999999982

Please try following

if ([ $dateR -ge 234 ] && [ $dateR -lt 238 ]) || ([ $dateR -ge 834 ] && [ $dateR -lt 838 ]) || ([ $dateR -ge 1434 ] && [ $dateR -lt 1438 ]) || ([ $dateR -ge 2034 ] && [ $dateR -lt 2038 ]) ;
then
    echo "WORKING"
else
    echo "Out of range!"

if ([statusString isEqualToString:@"Wrong"]) {
    // do something
}

You can $apply your changes only if $apply is not already in progress. You can update your code as

if(!$scope.$$phase) $scope.$apply();

For Swift:

self.tableView.tableFooterView = UIView(frame: CGRectZero)

For newest Swift:

self.tableView.tableFooterView = UIView(frame: CGRect.zero)

3 things to remember:

• set the android:layout_width of the children to "0dp"
• set the android:weightSum of the parent (edit: as Jason Moore noticed, this attribute is optional, because by default it is set to the children's layout_weight sum)
• set the android:layout_weight of each child proportionally (e.g. weightSum="5", three children: layout_weight="1", layout_weight="3", layout_weight="1")

Example:

    <LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:weightSum="5">

    <Button
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="1" />

    <Button
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="3"
        android:text="2" />

    <Button
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="3" />

    </LinearLayout>

And the result:

Using Python 3 you can have both required and non-required keyword arguments:

Optional: (default value defined for param 'b')

def func1(a, *, b=42):
    ...
func1(value_for_a) # b is optional and will default to 42

Required (no default value defined for param 'b'):

def func2(a, *, b):
    ... 
func2(value_for_a, b=21) # b is set to 21 by the function call
func2(value_for_a) # ERROR: missing 1 required keyword-only argument: 'b'`

This can help in cases where you have many similar arguments next to each other especially if they are of the same type, in that case I prefer using named arguments or I create a custom class if arguments belong together.

I recommend IdentityServer.This is a .NET Foundation project and covers many issues about authentication and authorization.

Overview

IdentityServer is a .NET/Katana-based framework and hostable component that allows implementing single sign-on and access control for modern web applications and APIs using protocols like OpenID Connect and OAuth2. It supports a wide range of clients like mobile, web, SPAs and desktop applications and is extensible to allow integration in new and existing architectures.

For more information, e.g.

• support for MembershipReboot and ASP.NET Identity based user stores
• support for additional Katana authentication middleware (e.g. Google, Twitter, Facebook etc)
• support for EntityFramework based persistence of configuration
• support for WS-Federation
• extensibility

check out the documentation and the demo.

if(UI_USER_INTERFACE_IDIOM () == UIUserInterfaceIdiom.pad)
 {
            print("This is iPad")
 }else if (UI_USER_INTERFACE_IDIOM () == UIUserInterfaceIdiom.phone)
 {
            print("This is iPhone");
  }

This isn't an exact answer to the question, but one other option for phone validation, is to ensure the number gets entered in the format you are expecting.

Here is a function I have worked on that when set to the onInput event, will strip any non-numerical inputs, and auto-insert dashes at the "right" spot, assuming xxx-xxx-xxxx is the desired output.

<input oninput="formatPhone()">

function formatPhone(e) {
    var x = e.target.value.replace(/\D/g, '').match(/(\d{0,3})(\d{0,3})(\d{0,4})/);
    e.target.value = !x[2] ? x[1] : x[1] + '-' + x[2] + (x[3] ? '-' + x[3] : '');
}

Question is a bit old, but easy way is to apply .center-block to button.

jQuery API documentation - datepicker

The minimum selectable date. When set to null, there is no minimum.

Multiple types supported:

Date: A date object containing the minimum date.
Number: A number of days from today. For example 2 represents two days from today and -1 represents yesterday.
String: A string in the format defined by the dateFormat option, or a relative date.
Relative dates must contain value and period pairs; valid periods are y for years, m for months, w for weeks, and d for days. For example, +1m +7d represents one month and seven days from today.

In order not to display previous dates other than today

$('#datepicker').datepicker({minDate: 0});

$ awk '{print $NF}' file.txt | paste -sd, | sed 's/,/, /g'

For a file like this

$ cat file.txt
The quick brown fox
jumps over
the lazy dog.

the given command will print

fox, over, dog.

How it works:

• awk '{print $NF}' : prints the last field of every line
• paste -sd, : reads stdin serially (-s, one file at a time) and writes fields comma-delimited (-d,)
• sed 's/,/, /g' : substitutes "," with ", " globally (for all instances)

Integer Array doesn't contain size() or length() method. Try the below code, it'll work. ArrayList contains size() method. String contains length(). Since you have used int array[], so it will be array.length

public class Example {

    int array[] = {1, 99, 10000, 84849, 111, 212, 314, 21, 442, 455, 244, 554, 22, 22, 211};

    public void Printrange() {

        for (int i = 0; i < array.length; i++) {
            if (array[i] > 100 && array[i] < 500) {
                System.out.println("numbers with in range" + i);
            }
        }
    }
}

Another option is to adjust udev, which controls how devices are mounted and with what privileges. Useful to allow non-root access to serial devices. If you have permanently attached devices, the --device option is the best way to go. If you have ephemeral devices, here's what I've been using:

1. Set udev rule

By default, serial devices are mounted so that only root users can access the device. We need to add a udev rule to make them readable by non-root users.

Create a file named /etc/udev/rules.d/99-serial.rules. Add the following line to that file:

KERNEL=="ttyUSB[0-9]*",MODE="0666"

MODE="0666" will give all users read/write (but not execute) permissions to your ttyUSB devices. This is the most permissive option, and you may want to restrict this further depending on your security requirements. You can read up on udev to learn more about controlling what happens when a device is plugged into a Linux gateway.

2. Mount in /dev folder from host to container

Serial devices are often ephemeral (can be plugged and unplugged at any time). Because of this, we can’t mount in the direct device or even the /dev/serial folder, because those can disappear when things are unplugged. Even if you plug them back in and the device shows up again, it’s technically a different file than what was mounted in, so Docker won’t see it. For this reason, we mount the entire /dev folder from the host to the container. You can do this by adding the following volume command to your Docker run command:

-v /dev:/dev

If your device is permanently attached, then using the --device option or a more specific volume mount is likely a better option from a security perspective.

3. Run container in privileged mode

If you did not use the --device option and mounted in the entire /dev folder, you will be required to run the container is privileged mode (I'm going to check out the cgroup stuff mentioned above to see if this can be removed). You can do this by adding the following to your Docker run command:

--privileged

4. Access device from the /dev/serial/by-id folder

If your device can be plugged and unplugged, Linux does not guarantee it will always be mounted at the same ttyUSBxxx location (especially if you have multiple devices). Fortunately, Linux will make a symlink automatically to the device in the /dev/serial/by-id folder. The file in this folder will always be named the same.

This is the quick rundown, I have a blog article that goes into more details.

Follow the steps below.

This is what worked for me. Issue is earlier I didn't set Content Type(header) when I used exchange method.

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
        headers);
JSONObject jsonObject = null;

try {
    RestTemplate restTemplate = new RestTemplate();
    ResponseEntity<String> responseEntity = restTemplate.exchange(
            "https://url", HttpMethod.POST, entity,
            String.class);

    if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
        try {
            jsonObject = new JSONObject(responseEntity.getBody());
        } catch (JSONException e) {
            throw new RuntimeException("JSONException occurred");
        }
    }
  } catch (final HttpClientErrorException httpClientErrorException) {
        throw new ExternalCallBadRequestException();
  } catch (HttpServerErrorException httpServerErrorException) {
        throw new ExternalCallServerErrorException(httpServerErrorException);
  } catch (Exception exception) {
        throw new ExternalCallServerErrorException(exception);
    } 

ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.

Note: Remember HttpClientErrorException is thrown when a 4xx error is received. So if the request you send is wrong either setting header or sending wrong data, you could receive this exception.

It helps not to focus on the strong or weak part of the discussion. Instead focus on the cycle part.

A retain cycle is a loop that happens when Object A retains Object B, and Object B retains Object A. In that situation, if either object is released:

• Object A won't be deallocated because Object B holds a reference to it.
• But Object B won't ever be deallocated as long as Object A has a reference to it.
• But Object A will never be deallocated because Object B holds a reference to it.
• ad infinitum

Thus, those two objects will just hang around in memory for the life of the program even though they should, if everything were working properly, be deallocated.

So, what we're worried about is retain cycles, and there's nothing about blocks in and of themselves that create these cycles. This isn't a problem, for example:

[myArray enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop){
   [self doSomethingWithObject:obj];
}];

The block retains self, but self doesn't retain the block. If one or the other is released, no cycle is created and everything gets deallocated as it should.

Where you get into trouble is something like:

//In the interface:
@property (strong) void(^myBlock)(id obj, NSUInteger idx, BOOL *stop);

//In the implementation:
[self setMyBlock:^(id obj, NSUInteger idx, BOOL *stop) {
  [self doSomethingWithObj:obj];     
}];

Now, your object (self) has an explicit strong reference to the block. And the block has an implicit strong reference to self. That's a cycle, and now neither object will be deallocated properly.

Because, in a situation like this, self by definition already has a strong reference to the block, it's usually easiest to resolve by making an explicitly weak reference to self for the block to use:

__weak MyObject *weakSelf = self;
[self setMyBlock:^(id obj, NSUInteger idx, BOOL *stop) {
  [weakSelf doSomethingWithObj:obj];     
}];

But this should not be the default pattern you follow when dealing with blocks that call self! This should only be used to break what would otherwise be a retain cycle between self and the block. If you were to adopt this pattern everywhere, you'd run the risk of passing a block to something that got executed after self was deallocated.

//SUSPICIOUS EXAMPLE:
__weak MyObject *weakSelf = self;
[[SomeOtherObject alloc] initWithCompletion:^{
  //By the time this gets called, "weakSelf" might be nil because it's not retained!
  [weakSelf doSomething];
}];

Do ctrl+F5 to compile and run your project without debugging. Look at the output pane (defaults to "Show output from Build"). If it compiled successfully, the path to the .exe file should be there after {projectname}.vcxproj ->

public static void Fill<T>(this IList<T> col, T value, int fromIndex, int toIndex)
{
    if (fromIndex > toIndex)
        throw new ArgumentOutOfRangeException("fromIndex");

    for (var i = fromIndex; i <= toIndex; i++)
        col[i] = value;
}

Something that works for all IList<T>s.

Previous answer doesn't work for me :( But it's OK like that :)

         $data = json_decode(
              iconv(
                  mb_detect_encoding($data, mb_detect_order(), true),
                  'CP1252',
                  json_encode($data)
                )
              , true)

In the App domain section, you are writing your app domain but you also need to add your login domain i.e. the name of html page where you ask user to login. In my case, I was testing it on localhost and the login route was localhost/login, If I only put http://localhost.com in App domain section, I get this error. But after adding http://localhost/login.com, the error was fixed. and also the App settings has changed in newer version of SDK, in which there is no option for OAuth redirect route. You've to assign the redirect route directly from server side, after successfully getting OAuth token.

I think that the best approach is to assign the onclick handler unobtrusively.

Something like this:

window.onload = function(){
    var myLink = document.getElementsById('myLinkId');
    myLink.onclick = function(){ 
        parse('#', false, '<a href="xyz');
        return false;
    }
}

//...


<a href="#" id="myLink">Test</a>

I've had these problems a number of times. I've come to this same page a lot. In my last problem I had to run the server from a fixed directory, but whenever debugging I wanted to run from different sub-directories.

import sys
sys.insert(1, /path) 

did NOT work for me because at different modules I had to read different *.csv files which were all in the same directory.

In the end, what worked for me was not pythonic, I guess, but:

I used a if __main__ on top of the module I wanted to debug, that is run from a different than usual path.

So:

# On top of the module, instead of on the bottom
import os
if __name__ == '__main__':
    os.chdir('/path/for/the/regularly/run/directory')

Solved it as follows,

in CSS

#my{
zoom: 100%;
}

Now, it loads in 100% zoom by default. Tested it by giving 290% zoom and it loaded by that zoom percentage on default, it's upto the user if he wants to change zoom.

Though this is not the best way to do it, there is another effective solution

Check the page code of stack over flow, even they have buttons and they use un ordered lists to solve this problem.

To set the range of the x-axis, you can use set_xlim(left, right), here are the docs

Update:

It looks like you want an identical plot, but only change the 'tick values', you can do that by getting the tick values and then just changing them to whatever you want. So for your need it would be like this:

ticks = your_plot.get_xticks()*10**9
your_plot.set_xticklabels(ticks)

When you store something in an array , its size needs to be known (since array indexing relies on the size). Per the C++ standard It is unspecified whether or not a reference requires storage, as a result indexing an array of references would not be possible.

This isn't directly possible with Basic-Authentication.

There's no mechanism in the HTTP specification for the server to tell the browser to stop sending the credentials that the user already presented.

There are "hacks" (see other answers) typically involving using XMLHttpRequest to send an HTTP request with incorrect credentials to overwrite the ones originally supplied.

Your code works fine. You can verify the RGB colors with Iconfactory's xScope. Just compare it to [UIColor whiteColor].

You appear to have a heredoc containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF

or if BUILDING is $2 in your script:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF

If your file.sql had an exit at the end then it would be even simpler as you wouldn't need the heredoc:

sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2

In your SQL you can then refer to the position parameters using substitution variables:

...
}',SEM_Models('&1'),NULL,

The &1 will be replaced with the first value passed to the SQL script, BUILDING; because that is a string it still needs to be enclosed in quotes. You might want to set verify off to stop if showing you the substitutions in the output.

You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1, the second is &2, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF

or:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF

If total_count is being passed to your shell script then just use its positional parameter, $4 or whatever. And your SQL would then be:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:

define MY_ALIAS = &1
define MY_MODEL = &2

SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

From your separate question, maybe you just wanted:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

... so the alias will be the same value you're querying on (the value in $2, or BUILDING in the original part of the answer). You can refer to a substitution variable as many times as you want.

That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:

select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT

If you set pages 0 and set heading off, your repeated calls might appear in a neat list. You might also need to set tab off and possibly use rpad('&1', 20) or similar to make that column always the same width. Or get the results as CSV with:

select '&1' ||','|| COUNT(*)

Depends what you're using the results for...

Position your <div> absolutely at the bottom and don't forget to give div.A a position: relative - http://jsfiddle.net/TTaMx/

    .A {
        position: relative;
        margin: 40px 0;
        height: 40px;
        width: 200px;
        background: #eee;
    }

    .A:after {
        content: " ";
        display: block;
        background: #c00;
        height: 29px;
        width: 100%;

        position: absolute;
        bottom: -29px;
    }?

give this a try,

insert into tableName (ImageColumn) 
SELECT BulkColumn 
FROM Openrowset( Bulk 'image..Path..here', Single_Blob) as img

INSERTING

REFRESHING THE TABLE

All work perfectly :)

 NSString *test = @"test";
 unichar a;
 int index = 5;
    
 @try {
    a = [test characterAtIndex:index];
 }
 @catch (NSException *exception) {
    NSLog(@"%@", exception.reason);
    NSLog(@"Char at index %d cannot be found", index);
    NSLog(@"Max index is: %lu", [test length] - 1);
 }
 @finally {
    NSLog(@"Finally condition");
 }

Log:

[__NSCFConstantString characterAtIndex:]: Range or index out of bounds

Char at index 5 cannot be found

Max index is: 3

Finally condition

You need to use web services. In the above code I have php web service to be used which has a callback function which is optional. Assuming you know HTML5 I did not post the html code. In the url you can send the details to the web server.

my string

var obj = {"Status":0,"Data":{"guid":"","invitationGuid":"","entityGuid":"387E22AD69-4910-430C-AC16-8044EE4A6B24443545DD"},"Extension":null}

Following code to get guid:

var userObj = JObject.Parse(obj);
var userGuid = Convert.ToString(userObj["Data"]["guid"]);
