sudo apt-get install graphicsmagick-libmagick-dev-compat

did the trick for me

If you have access to a console in the context you are investigating, you can determine which version you are running by printing the value of the global constant RUBY_VERSION.

As the instruction said "might need gpg2"

In mac, you can try install it with homebrew

$ brew install gpg2 

     Usually this is caused by shell initialization files. Search for PATH=... entries.
     You can also re-add RVM to your profile by running: rvm get stable --auto-dotfiles
     To fix it temporarily in this shell session run: rvm use ruby-2.6.5
     To ignore this error add "rvm_silence_path_mismatch_check_flag=1" to your "~/.rvmrc" file.

It’s easy; just do the following:

rvm implode

or

rm -rf ~/.rvm

And don’t forget to remove the script calls in the following files:

• ~/.bashrc
• ~/.bash_profile
• ~/.profile

And maybe others depending on whatever shell you’re using.

• Open Terminal.
• Go to Edit -> Profile Preferences.
• Select the Title & command Tab in the window opened.
• Mark the checkbox Run command as login shell.
• close the window and restart the Terminal.

Per RVM's troubleshooting documentation "How do I completely clean out all traces of RVM from my system, including for system wide installs?":

Here is a custom script which we name as 'cleanout-rvm'. While you can definitely use rvm implode as a regular user or rvmsudo rvm implode for a system wide install, this script is useful as it steps completely outside of RVM and cleans out RVM without using RVM itself, leaving no traces.

#!/bin/bash
/usr/bin/sudo rm -rf $HOME/.rvm $HOME/.rvmrc /etc/rvmrc /etc/profile.d/rvm.sh /usr/local/rvm /usr/local/bin/rvm
/usr/bin/sudo /usr/sbin/groupdel rvm
/bin/echo "RVM is removed. Please check all .bashrc|.bash_profile|.profile|.zshrc for RVM source lines and delete or comment out if this was a Per-User installation."

If you want to use the non-SSL source, try removing the HTTPS source first, and then adding the HTTP one:

sudo gem sources -r https://rubygems.org
sudo gem sources -a http://rubygems.org  

UPDATE:

As mpapis states, this should be used only as a temporary workaround. There could be some security concerns if you're accessing RubyGems through the non-SSL source.

Once the workaround is not needed anymore, you should restore the SSL-source:

sudo gem sources -r http://rubygems.org
sudo gem sources -a https://rubygems.org

The error shows you either didn't create the rails project yet or you're not in the rails project directory.

Suppose if you're working on myapp project. You've to move to that project directory on your command line and then generate the model. Here are some steps you can refer.

Example: Assuming you didn't create the Rails app yet:

$> rails new myapp
$> cd myapp

Now generate the model from your commandline.

$> rails generate model your_model_name 

For renaming your index you can use Elasticsearch Snapshot module.

First you have to take snapshot of your index.while restoring it you can rename your index.

    POST /_snapshot/my_backup/snapshot_1/_restore
    {
     "indices": "jal",
     "ignore_unavailable": "true",
     "include_global_state": false,
     "rename_pattern": "jal",
     "rename_replacement": "jal1"
     }

rename_replacement :-New indexname in which you want backup your data.

If you bind events to the onmouseover and onmouseout events in Jquery, you can then trigger that effect using mouseenter().

What are you trying to accomplish?

This turned out to NOT be a bower problem, though it showed up for me with bower.

It seems to be a node-which problem. If a file is in the path, but has the setuid/setgid bit set, which will not find it.

Here is a files with the s bit set: (unix 'which' will find it with no problems).

ls -al /usr/local/bin -rwxrwsr-- 110 root nmt 5535636 Jul 17 2012 git

Here is a node-which attempt:

> which.sync('git')
Error: not found: git

I change the permissions (chomd 755 git). Now node-which can find it.

> which.sync('git')
'/usr/local/bin/git'

Hope this helps.

First, you need to convert your string to NSDate with its format. Then, you change the dateFormatter to your simple format and convert it back to a String.

Swift 3

let dateString = "Thu, 22 Oct 2015 07:45:17 +0000"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "EEE, dd MMM yyyy hh:mm:ss +zzzz"
dateFormatter.locale = Locale.init(identifier: "en_GB")

let dateObj = dateFormatter.date(from: dateString)

dateFormatter.dateFormat = "MM-dd-yyyy"
print("Dateobj: \(dateFormatter.string(from: dateObj!))")

The printed result is: Dateobj: 10-22-2015

There are primarily 2 solutions for this:

1. You need to specify the branch name with -b command switch. Here is the syntax of the command to clone the specific git branch.

   git clone -b <BRANCH_NAME> <GIT_REMOTE_URL>
   

   Example:

   git clone -b tahir https://github.com/Repository/Project.git
   

   The following command will clone the branch tahir from the git repository.The above command clones only the specific branch but fetches the details of other branches. You can view all branches details with command.

   git branch -a
   

2. You can use --single-branch flag to prevent fetching details of other branches like below:

   git clone -b <BRANCH_NAME> --single-branch <GIT_REMOTE_URL>
   

   Example:

   git clone -b tahir --single-branch \ 
   https://github.com/Repository/Project.git
   

   Now if you do a git branch -a, it will only show your current single branch that you have cloned and not all the branches. So it depends on you how you want it.

If you want to redirect HTTP to HTTPS and want to add www with each URL, use the htaccess below

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}/$1 [R=301,L] 

it will first redirect HTTP to HTTPS and then it will redirect to www.

@variable is very useful if calling stored procedures from an application written in Java , Python etc. There are ocassions where variable values are created in the first call and needed in functions of subsequent calls.

Side-note on PL/SQL (Oracle)

The advantage can be seen in Oracle PL/SQL where these variables have 3 different scopes:

• Function variable for which the scope ends when function exits.
• Package body variables defined at the top of package and outside all functions whose scope is the session and visibility is package.
• Package variable whose variable is session and visibility is global.

My Experience in PL/SQL

I have developed an architecture in which the complete code is written in PL/SQL. These are called from a middle-ware written in Java. There are two types of middle-ware. One to cater calls from a client which is also written in Java. The other other one to cater for calls from a browser. The client facility is implemented 100 percent in JavaScript. A command set is used instead of HTML and JavaScript for writing application in PL/SQL.

I have been looking for the same facility to port the codes written in PL/SQL to another database. The nearest one I have found is Postgres. But all the variables have function scope.

Opinion towards @ in MySQL

I am happy to see that at least this @ facility is there in MySQL. I don't think Oracle will build same facility available in PL/SQL to MySQL stored procedures since it may affect the sales of Oracle database.

Eloquent has a method for that (Laravel 4.*/5.*);

Model::whereNotNull('sent_at')

Laravel 3:

Model::where_not_null('sent_at')

Better solution is to introduce another interface for async operations. New interface must inherit from original interface.

Example:

interface IIO
{
    void DoOperation();
}

interface IIOAsync : IIO
{
    Task DoOperationAsync();
}


class ClsAsync : IIOAsync
{
    public void DoOperation()
    {
        DoOperationAsync().GetAwaiter().GetResult();
    }

    public async Task DoOperationAsync()
    {
        //just an async code demo
        await Task.Delay(1000);
    }
}


class Program
{
    static void Main(string[] args)
    {
        IIOAsync asAsync = new ClsAsync();
        IIO asSync = asAsync;

        Console.WriteLine(DateTime.Now.Second);

        asAsync.DoOperation();
        Console.WriteLine("After call to sync func using Async iface: {0}", 
            DateTime.Now.Second);

        asAsync.DoOperationAsync().GetAwaiter().GetResult();
        Console.WriteLine("After call to async func using Async iface: {0}", 
            DateTime.Now.Second);

        asSync.DoOperation();
        Console.WriteLine("After call to sync func using Sync iface: {0}", 
            DateTime.Now.Second);

        Console.ReadKey(true);
    }
}

P.S. Redesign your async operations so they return Task instead of void, unless you really must return void.

Simple solution for this common annoying issue:

Just go to your ".context.cs" file (located under ".context.tt" which located under your "*.edmx" file).

Then, add this line to your constructor:

public DBEntities() 
        : base("name=DBEntities") 
    { 
        this.Configuration.ProxyCreationEnabled = false; // ADD THIS LINE !
    }

hope this is helpful.

This worked for me and I think this is the most basic solution which involves the least setup possible:

1. With your PC and other device connected to the same network , open cmd from your PC which you plan to set up as a server, and hit ipconfig to get your ip address. Note this ip address. It should be something like "192.168.1.2" which is the value to the right of IPv4 Address field as shown in below format:

Wireless LAN adapter Wi-Fi:

Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : ffff::ffff:ffff:ffff:ffad%14
IPv4 Address. . . . . . . . . . . : 192.168.1.2
Subnet Mask . . . . . . . . . . . : 255.255.255.0

2. Start your node server like this : npm start <IP obtained in step 1:3000> e.g. npm start 192.168.1.2:3000
3. Open browser of your other device and hit the url: <your_ip:3000> i.e. 192.168.1.2:3000 and you will see your website.

No, it's not the script, it's the fact that your script is not executed by Python at all. If your script is stored in a file named script.py, you have to execute it as python script.py, otherwise the default shell will execute it and it will bail out at the from keyword. (Incidentally, from is the name of a command line utility which prints names of those who have sent mail to the given username, so that's why it tries to access the mailboxes).

Another possibility is to add the following line to the top of the script:

#!/usr/bin/env python

This will instruct your shell to execute the script via python instead of trying to interpret it on its own.

To give custom parameters to facebook share its better to give only the link and facebook gets its Title + Description + Picture automatically from the page that you are sharing. In order to "help" facebook API find those things you can put the following things in the header of the page that you are sharing:

<meta property="og:title" content="title" />
<meta property="og:description" content="description" />
<meta property="og:image" content="thumbnail_image" />

Check here

If the page is not under your control use what AllisonC has shared above.

For popup modalview type behavior:

Use your own button/link/text and then you can use a modal view type of popup this way:

<script type= 'text/javascript'>
$('#twitterbtn-link,#facebookbtn-link').click(function(event) {
var width  = 575,
    height = 400,
    left   = ($(window).width()  - width)  / 2,
    top    = ($(window).height() - height) / 2,
    url    = this.href,
    opts   = 'status=1' +
             ',width='  + width  +
             ',height=' + height +
             ',top='    + top    +
             ',left='   + left;

window.open(url, 'twitter', opts);

return false;
});
</script>

where twitterbtn-link and facebookbtn-link are both ids of anchors.

Generally speaking, you can update your index mapping using the put mapping api (reference here) :

curl -XPUT 'http://localhost:9200/advert_index/_mapping/advert_type' -d '
{
    "advert_type" : {
        "properties" : {

          //your new mapping properties

        }
    }
}
'

It's especially useful for adding new fields. However, in your case, you will try to change the location type, which will cause a conflict and prevent the new mapping from being used.

You could use the put mapping api to add another property containing the location as a lat/lon array, but you won't be able to update the previous location field itself.

Finally, you will have to reindex your data for your new mapping to be taken into account.

The best solution would really be to create a new index.

If your problem with creating another index is downtime, you should take a look at aliases to make things go smoothly.

For me, It's working like this one.

C:\Program Files\PostgreSQL\12\bin> psql -U postgres -p 5432  -d dummy -f C:\Users\Downloads\d2cm_test.sql

I found this will have git ignore temporary files created by vim:

OK, got it working with this (creating the UIImageView programmatically):

var imageViewObject :UIImageView

imageViewObject = UIImageView(frame:CGRectMake(0, 0, 600, 600))

imageViewObject.image = UIImage(named:"afternoon")

self.view.addSubview(imageViewObject)

self.view.sendSubviewToBack(imageViewObject)

For creating test data in Rails you use this hack:

record = Something.new(attrs)
ActiveRecord::Persistence.instance_method(:create_record).bind(record).call

Let's say you additionally want the week to begin on Monday (instead of default on Sunday), then the following is helpful:

require(lubridate)
df$day = ifelse(wday(df$time)==1,6,wday(df$time)-2)

The result is the days in the interval [0,..,6].

If you want the interval to be [1,..7], use the following:

df$day = ifelse(wday(df$time)==1,7,wday(df$time)-1)

... or, alternatively:

df$day = df$day + 1

Your form is valid. Only thing that comes to my mind is, after seeing your full html, is that you're passing your "default" value (which is not set!) instead of selecting something. Try as suggested by @Vina in the comment, i.e. giving it a selected option, or writing a default value

<select name="gender">
<option value="default">Select </option>    
<option value="male">   Male   </option>
<option value="female"> Female </option>
</select>

OR

<select name="gender">
<option value="male" selected="selected">   Male   </option>
<option value="female"> Female </option>
</select>

When you get your $_POST vars, check for them being set; you can assign a default value, or just an empty string in case they're not there.

Most important thing, AVOID SQL INJECTIONS:

//....
$fname   = isset($_POST["fname"]) ? mysql_real_escape_string($_POST['fname']) : '';
$lname   = isset($_POST['lname']) ? mysql_real_escape_string($_POST['lname']) : '';
$email   = isset($_POST['email']) ? mysql_real_escape_string($_POST['email']) : '';
you might also want to validate e-mail:
if($mail = filter_var($_POST['email'], FILTER_VALIDATE_EMAIL))
{
  $email = mysql_real_escape_string($_POST['email']);
}
else
{
  //die ('invalid email address');
  // or whatever, a default value? $email = '';
}
$paswod  = isset($_POST["paswod"]) ? mysql_real_escape_string($_POST['paswod']) : '';
$gender  = isset($_POST['gender']) ? mysql_real_escape_string($_POST['gender']) : '';

$query = mysql_query("SELECT Email FROM users WHERE Email = '".$email."')";
if(mysql_num_rows($query)> 0)
{
  echo 'userid is already there';
}
else
{
 $sql = "INSERT INTO users (FirstName, LastName, Email, Password, Gender)
         VALUES ('".$fname."','".$lname."','".$email."','".paswod."','".$gender."')";
$res = mysql_query($sql) or die('Error:'.mysql_error());
echo 'created';

The throws Exception declaration is an automated way of keeping track of methods that might throw an exception for anticipated but unavoidable reasons. The declaration is typically specific about the type or types of exceptions that may be thrown such as throws IOException or throws IOException, MyException.

We all have or will eventually write code that stops unexpectedly and reports an exception due to something we did not anticipate before running the program, like division by zero or index out of bounds. Since the errors were not expected by the method, they could not be "caught" and handled with a try catch clause. Any unsuspecting users of the method would also not know of this possibility and their programs would also stop.

When the programmer knows certain types of errors may occur but would like to handle these exceptions outside of the method, the method can "throw" one or more types of exceptions to the calling method instead of handling them. If the programmer did not declare that the method (might) throw an exception (or if Java did not have the ability to declare it), the compiler could not know and it would be up to the future user of the method to know about, catch and handle any exceptions the method might throw. Since programs can have many layers of methods written by many different programs, it becomes difficult (impossible) to keep track of which methods might throw exceptions.

Even though Java has the ability to declare exceptions, you can still write a new method with unhandled and undeclared exceptions, and Java will compile it and you can run it and hope for the best. What Java won't let you do is compile your new method if it uses a method that has been declared as throwing exception(s), unless you either handle the declared exception(s) in your method or declare your method as throwing the same exception(s) or if there are multiple exceptions, you can handle some and throw the rest.

When a programmer declares that the method throws a specific type of exception, it is just an automated way of warning other programmers using the method that an exception is possible. The programmer can then decide to handled the exception or pass on the warning by declaring the calling method as also throwing the same exception. Since the compiler has been warned the exception is possible in this new method, it can automatically check if future callers of the new method handle the exception or declare it and enforcing one or the other to happen.

The nice thing about this type of solution is that when the compiler reports Error: Unhandled exception type java.io.IOException it gives the file and line number of the method that was declared to throw the exception. You can then choose to simply pass the buck and declare your method also "throws IOException". This can be done all the way up to main method where it would then cause the program to stop and report the exception to the user. However, it is better to catch the exception and deal with it in a nice way such as explaining to the user what has happened and how to fix it. When a method does catch and handle the exception, it no longer has to declare the exception. The buck stops there so to speak.

Easy done:

(?<=\[)(.*?)(?=\])

Technically that's using lookaheads and lookbehinds. See Lookahead and Lookbehind Zero-Width Assertions. The pattern consists of:

• is preceded by a [ that is not captured (lookbehind);
• a non-greedy captured group. It's non-greedy to stop at the first ]; and
• is followed by a ] that is not captured (lookahead).

Alternatively you can just capture what's between the square brackets:

\[(.*?)\]

and return the first captured group instead of the entire match.

You may want to try

var d = new Date();
d.toLocaleString();       // -> "2/1/2013 7:37:08 AM"
d.toLocaleDateString();   // -> "2/1/2013"
d.toLocaleTimeString();  // -> "7:38:05 AM"

You can do it very easily with a Cloud Management software -like enStratus, RightScale or Scalr (disclaimer: I work there). With the cloned farm you can:

1. Create a snapshot or a pre-made image to launch another day
2. Duplicate your configuration to test it before production

We've run into many edge cases when setting up permissions for Laravel applications. We create a separate user account (deploy) for owning the Laravel application folder and executing Laravel commands from the CLI, and run the web server under www-data. One issue this causes is that the log file(s) may be owned by www-data or deploy, depending on who wrote to the log file first, obviously preventing the other user from writing to it in the future.

I've found that the only sane and secure solution is to use Linux ACLs. The goal of this solution is:

1. To allow the user who owns/deploys the application read and write access to the Laravel application code (we use a user named deploy).
2. To allow the www-data user read access to Laravel application code, but not write access.
3. To prevent any other users from accessing the Laravel application code/data at all.
4. To allow both the www-data user and the application user (deploy) write access to the storage folder, regardless of which user owns the file (so both deploy and www-data can write to the same log file for example).

We accomplish this as follows:

1. All files within the application/ folder are created with the default umask of 0022, which results in folders having drwxr-xr-x permissions and files having -rw-r--r--.
2. sudo chown -R deploy:deploy application/ (or simply deploy your application as the deploy user, which is what we do).
3. chgrp www-data application/ to give the www-data group access to the application.
4. chmod 750 application/ to allow the deploy user read/write, the www-data user read-only, and to remove all permissions to any other users.
5. setfacl -Rdm u:www-data:rwx,u:deploy:rwx application/storage/ to set the default permissions on the storage/ folder and all subfolders. Any new folders/files created in the storage folder will inherit these permissions (rwx for both www-data and deploy).
6. setfacl -Rm u:www-data:rwX,u:deploy:rwX application/storage/ to set the above permissions on any existing files/folders.

Consider the following in order to handle the case of an empty string:

>>> my_string = 'A,B,C,D,E'
>>> my_string.split(",") if my_string else []
['A', 'B', 'C', 'D', 'E']
>>> my_string = ""
>>> my_string.split(",") if my_string else []
[]

find() - Limited to lookups by tag name

So if you're not using jQuery with Angular, but relying upon its jqlite implementation, you can't do elm.find('#someid').

You do have access to children(), contents(), and data() implementations, so you can usually find a way around it.

Including C file into another file is legal, but not advisable thing to do, unless you know exactly why are you doing this and what are you trying to achieve.
I'm almost sure that if you will post here the reason that behind your question the community will find you another more appropriate way to achieve you goal (please note the "almost", since it is possible that this is the solution given the context).

By the way i missed the second part of the question. If C file is included to another file and in the same time included to the project you probably will end up with duplicate symbol problem why linking the objects, i.e same function will be defined twice (unless they all static).

As Lucas says, what you are describing is the intended behaviour for the float property. What confuses many people is that float has been pushed well beyond its original intended usage in order to make up for shortcomings in the CSS layout model.

Have a look at Floatutorial if you'd like to get a better understanding of how this property works.

The accepted answer answers the question about getting a thread id, but it doesn't let you do "Thread X of Y" messages. Thread ids are unique across threads but don't necessarily start from 0 or 1.

Here is an example matching the question:

import java.util.concurrent.*;
class ThreadIdTest {

  public static void main(String[] args) {

    final int numThreads = 5;
    ExecutorService exec = Executors.newFixedThreadPool(numThreads);

    for (int i=0; i<10; i++) {
      exec.execute(new Runnable() {
        public void run() {
          long threadId = Thread.currentThread().getId();
          System.out.println("I am thread " + threadId + " of " + numThreads);
        }
      });
    }

    exec.shutdown();
  }
}

and the output:

burhan@orion:/dev/shm$ javac ThreadIdTest.java && java ThreadIdTest
I am thread 8 of 5
I am thread 9 of 5
I am thread 10 of 5
I am thread 8 of 5
I am thread 9 of 5
I am thread 11 of 5
I am thread 8 of 5
I am thread 9 of 5
I am thread 10 of 5
I am thread 12 of 5

A slight tweak using modulo arithmetic will allow you to do "thread X of Y" correctly:

// modulo gives zero-based results hence the +1
long threadId = Thread.currentThread().getId()%numThreads +1;

New results:

burhan@orion:/dev/shm$ javac ThreadIdTest.java && java ThreadIdTest  
I am thread 2 of 5 
I am thread 3 of 5 
I am thread 3 of 5 
I am thread 3 of 5 
I am thread 5 of 5 
I am thread 1 of 5 
I am thread 4 of 5 
I am thread 1 of 5 
I am thread 2 of 5 
I am thread 3 of 5 

You can use normal CSS selectors to select an element by name using jquery. Like this:

Button Code
<button type="button" name="mybutton">Click Me!</button>

Selector & Event Bind Code
$("button[name='mybutton']").click(function() {});

Removes trailing returns when importing from Excel. When you execute this, you may receive an error that there is no WHERE; ignore and execute.

UPDATE table_name SET col_name = TRIM(TRAILING '\r' FROM col_name)

First Rule of a Prime: If divided by 2 equals a whole number or integer No its not prime.

Fastest method to Know using any computer language is type matching using strings not math. Match the DOT in a stringed Float.

• Divide it by 2,,, n = n / 2
• Convert this to a string,,, n = string(n)
• if "." in n: { printf "Yes I Am Prime !"
  }

I like using fsockopen open for this.

As a quick example (using a slightly cleaner method than the potentially duplicate question):

import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)

ax.plot(range(10))
ax.set_xlabel('X-axis')
ax.set_ylabel('Y-axis')

ax.spines['bottom'].set_color('red')
ax.spines['top'].set_color('red')
ax.xaxis.label.set_color('red')
ax.tick_params(axis='x', colors='red')

plt.show()

Alternatively

[t.set_color('red') for t in ax.xaxis.get_ticklines()]
[t.set_color('red') for t in ax.xaxis.get_ticklabels()]

It is important to be specific about what exception you're trying to catch when using a try/except block.

string = "abcd"
try:
    string_int = int(string)
    print(string_int)
except ValueError:
    # Handle the exception
    print('Please enter an integer')

Try/Excepts are powerful because if something can fail in a number of different ways, you can specify how you want the program to react in each fail case.

The best example is this one, No hiding, No jQuery, It's completely pure CSS

It may be a little late for the original question but for future queries this might help. Best way to achieve this is Get the result of the inner query to an array like this

$this->db->select('id');
$result = $this->db->get('your_table');
return  $result->result_array();

And then use than array in the following active record clause

$this->db->where_not_in('id_of_another_table', 'previously_returned_array');

Hope this helps

        { 
            alert("empty input file"); 

        } 
        return false; 

    });

I followed brain storm's instructions and still wasn't getting different results - any new terminal windows would not recognize the mvn command. I don't know why, but breaking out the declarations in smaller chunks .bash_profile worked. As far as I can tell, I'm essentially doing the same thing he did. Here's what looks different in my .bash_profile:

You can use PyPNG. It's a pure Python (no dependencies) open source PNG encoder/decoder and it supports writing NumPy arrays as images.

_{The question is old but I felt the best answer hadn't been given, yet.}

Is there an UPDATE syntax ... without specifying the column names?

General solution with dynamic SQL

You don't need to know any column names except for some unique column(s) to join on (id in the example). Works reliably for any possible corner case I can think of.

This is specific to PostgreSQL. I am building dynamic code based on the the information_schema, in particular the table information_schema.columns, which is defined in the SQL standard and most major RDBMS (except Oracle) have it. But a DO statement with PL/pgSQL code executing dynamic SQL is totally non-standard PostgreSQL syntax.

DO
$do$
BEGIN

EXECUTE (
SELECT
  'UPDATE b
   SET   (' || string_agg(        quote_ident(column_name), ',') || ')
       = (' || string_agg('a.' || quote_ident(column_name), ',') || ')
   FROM   a
   WHERE  b.id = 123
   AND    a.id = b.id'
FROM   information_schema.columns
WHERE  table_name   = 'a'       -- table name, case sensitive
AND    table_schema = 'public'  -- schema name, case sensitive
AND    column_name <> 'id'      -- all columns except id
);

END
$do$;

Assuming a matching column in b for every column in a, but not the other way round. b can have additional columns.

WHERE b.id = 123 is optional, to update a selected row.

SQL Fiddle.

• Dynamic UPDATE fails due to unwanted parenthesis around string in plpgsql

Partial solutions with plain SQL

With list of shared columns

You still need to know the list of column names that both tables share. With a syntax shortcut for updating multiple columns - shorter than what other answers suggested so far in any case.

UPDATE b
SET   (  column1,   column2,   column3)
    = (a.column1, a.column2, a.column3)
FROM   a
WHERE  b.id = 123    -- optional, to update only selected row
AND    a.id = b.id;

SQL Fiddle.

This syntax was introduced with Postgres 8.2 in 2006, long before the question was asked. Details in the manual.

Related:

• Bulk update of all columns

With list of columns in B

If all columns of A are defined NOT NULL (but not necessarily B),
and you know the column names of B (but not necessarily A).

UPDATE b
SET   (column1, column2, column3, column4)
    = (COALESCE(ab.column1, b.column1)
     , COALESCE(ab.column2, b.column2)
     , COALESCE(ab.column3, b.column3)
     , COALESCE(ab.column4, b.column4)
      )
FROM (
   SELECT *
   FROM   a
   NATURAL LEFT JOIN  b -- append missing columns
   WHERE  b.id IS NULL  -- only if anything actually changes
   AND    a.id = 123    -- optional, to update only selected row
   ) ab
WHERE b.id = ab.id;

The NATURAL LEFT JOIN joins a row from b where all columns of the same name hold same values. We don't need an update in this case (nothing changes) and can eliminate those rows early in the process (WHERE b.id IS NULL).
We still need to find a matching row, so b.id = ab.id in the outer query.

db<>fiddle here
Old sqlfiddle.

This is standard SQL except for the FROM clause.
It works no matter which of the columns are actually present in A, but the query cannot distinguish between actual NULL values and missing columns in A, so it is only reliable if all columns in A are defined NOT NULL.

There are multiple possible variations, depending on what you know about both tables.

string minusvalue = TextBox1.Text.ToString();

if (Convert.ToDouble(minusvalue) < 0)
{ 
    // set color of text in TextBox1 to red color and bold.
    TextBox1.ForeColor = Color.Red;
}

Button btn = (Button) findViewById(R.id.button1);

btn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent myIntent = new Intent(MainActivity.this, MainActivity2.class);
        MainActivity.this.startActivity(myIntent);       
    }  
});

The answer for the complete noob from a complete noob: MainActivity is the name of the first activity. MainActivity2 is the name of the second activity. button1 is the I.D of the button in xml for MainActivity Activity.

I favor the dplyr approach.

group_by(id) followed by either

• filter(row_number()==1) or
• slice(1) or
• slice_head(1) #(dplyr => 1.0)
• top_n(n = -1)
  • top_n() internally uses the rank function. Negative selects from the bottom of rank.

In some instances arranging the ids after the group_by can be necessary.

library(dplyr)

# using filter(), top_n() or slice()

m1 <-
test %>% 
  group_by(id) %>% 
  filter(row_number()==1)

m2 <-
test %>% 
  group_by(id) %>% 
  slice(1)

m3 <-
test %>% 
  group_by(id) %>% 
  top_n(n = -1)

All three methods return the same result

# A tibble: 5 x 2
# Groups:   id [5]
     id string
  <int> <fct> 
1     1 A     
2     2 B     
3     3 C     
4     4 D     
5     5 E

You can also use the read-only property key. It also respects special keys like shift etc. and is supported by IE9.

When a non-printable or special character is pressed, the value will be on of the defined key values like 'Shift' or 'Multiply'.

• Keyboard     event.key
• X             -> 'x'
• Shift+X -> 'X'
• F5            -> 'F5'

Try the JavaScript in operator.

if ('key' in myObj)

And the inverse.

if (!('key' in myObj))

Be careful! The in operator matches all object keys, including those in the object's prototype chain.

Use myObj.hasOwnProperty('key') to check an object's own keys and will only return true if key is available on myObj directly:

myObj.hasOwnProperty('key')

Unless you have a specific reason to use the in operator, using myObj.hasOwnProperty('key') produces the result most code is looking for.

another option is to use regex. The following code makes the search insensitive to upper/lower case:

bool endsWithIgnoreCase(const std::string& str, const std::string& suffix) {
  return std::regex_search(str,
     std::regex(std::string(suffix) + "$", std::regex_constants::icase));
}

probably not so efficient, but easy to implement.

If what you want is to hide the navigation bar completely in the controller, a much cleaner solution is to, in the root controller, have something like:

@implementation MainViewController
- (void)viewDidLoad {
    self.navigationController.navigationBarHidden=YES;
    //...extra code on view load  
}

When you push a child view in the controller, the Navigation Bar will remain hidden; if you want to display it just in the child, you'll add the code for displaying it(self.navigationController.navigationBarHidden=NO;) in the viewWillAppear callback, and similarly the code for hiding it on viewWillDisappear

If you're putting this in a string within a program, you may actually need to use four backslashes (because the string parser will remove two of them when "de-escaping" it for the string, and then the regex needs two for an escaped regex backslash).

For instance:

regex("\\\\")

is interpreted as...

regex("\\" [escaped backslash] followed by "\\" [escaped backslash])

is interpreted as...

regex(\\)

is interpreted as a regex that matches a single backslash.

Depending on the language, you might be able to use a different form of quoting that doesn't parse escape sequences to avoid having to use as many - for instance, in Python:

re.compile(r'\\')

The r in front of the quotes makes it a raw string which doesn't parse backslash escapes.

When you want to show an URL of remote branches, try:

git remote -v

Java doesn't have the concept of optional parameters with default values either in constructors or in methods. You're basically stuck with overloading. However, you chain constructors easily so you don't need to repeat the code:

public Foo(int param1, int param2)
{
    this.param1 = param1;
    this.param2 = param2;
}

public Foo(int param1)
{
    this(param1, 2);
}

Not sure exactly what you try to denote with that syntax, but in almost all RDBMS-es you can use a subquery in the FROM clause (sometimes called an "inline-view"):

SELECT..
FROM (
     SELECT ...
     FROM ...
     ) my_select
WHERE ...

In advanced "enterprise" RDBMS-es (like oracle, SQL Server, postgresql) you can use common table expressions which allows you to refer to a query by name and reuse it even multiple times:

-- Define the CTE expression name and column list.
WITH Sales_CTE (SalesPersonID, SalesOrderID, SalesYear)
AS
-- Define the CTE query.
(
    SELECT SalesPersonID, SalesOrderID, YEAR(OrderDate) AS SalesYear
    FROM Sales.SalesOrderHeader
    WHERE SalesPersonID IS NOT NULL
)
-- Define the outer query referencing the CTE name.
SELECT SalesPersonID, COUNT(SalesOrderID) AS TotalSales, SalesYear
FROM Sales_CTE
GROUP BY SalesYear, SalesPersonID
ORDER BY SalesPersonID, SalesYear;

(example from http://msdn.microsoft.com/en-us/library/ms190766(v=sql.105).aspx)

<meta charset='utf-8'> overrides the apache default charset (cf /etc/apache2/conf.d/charset)

If this is not enough, then you probably created your original file with iso-8859-1 encoding character set. You have to convert it to the proper character set:

iconv -f ISO-8859-1 -t UTF-8 source_file.php -o new file.php

This should do what you're looking for.

CSS:

html, body {
    height: 100%;
    margin: 0;
}

.gif-container {
  background: url("image.gif") center;
  background-size: cover;

  height: 100%;
}

HTML:

<div class="gif-container"></div>

Just replace the "\n" with "".

In vi/Vim for every line in the document:

%s/>\n_/>_/g

If you want to confirm every replacement:

%s/>\n_/>_/gc

For anybody falling on this old solution. There is a better way from the mongoose docs.

var s = new Schema({ name: { type: String, unique: true }});
s.path('name').index({ unique: true });

function tinyFriends() {
    let myFriends = ["Mukit", "Ali", "Umor", "sabbir"]
    let smallestFridend = myFriends[0];
    for (i = 0; i < myFriends.length; i++) {
        if (myFriends[i] < smallestFridend) {
            smallestFridend = myFriends[i];
        }
    }
    return smallestFridend   
}

SELECT datetime(CURRENT_TIMESTAMP, 'localtime')

Another option would be to use join

var mystr = "Matayoshi";
mystr = ["Mariano", mystr].join(' ');

You can use get methods:

var fullDate = new Date();_x000D_
console.log(fullDate);_x000D_
var twoDigitMonth = fullDate.getMonth() + "";_x000D_
if (twoDigitMonth.length == 1)_x000D_
    twoDigitMonth = "0" + twoDigitMonth;_x000D_
var twoDigitDate = fullDate.getDate() + "";_x000D_
if (twoDigitDate.length == 1)_x000D_
    twoDigitDate = "0" + twoDigitDate;_x000D_
var currentDate = twoDigitDate + "/" + twoDigitMonth + "/" + fullDate.getFullYear(); console.log(currentDate);

override func viewDidLoad() {

    let backgroundImage = UIImageView(frame: UIScreen.main.bounds)
    backgroundImage.image = UIImage(named: "bg_image")
    backgroundImage.contentMode = UIViewContentMode.scaleAspectfill
    self.view.insertSubview(backgroundImage, at: 0)

}

Updated at 20-May-2020:

The code snippet above doesn't work well after rotating the device. Here is the solution which can make the image stretch according to the screen size(after rotating):

class ViewController: UIViewController {

    var imageView: UIImageView = {
        let imageView = UIImageView(frame: .zero)
        imageView.image = UIImage(named: "bg_image")
        imageView.contentMode = .scaleToFill
        imageView.translatesAutoresizingMaskIntoConstraints = false
        return imageView
    }()

    override func viewDidLoad() {
        super.viewDidLoad()

        view.insertSubview(imageView, at: 0)
        NSLayoutConstraint.activate([
            imageView.topAnchor.constraint(equalTo: view.topAnchor),
            imageView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
            imageView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
            imageView.bottomAnchor.constraint(equalTo: view.bottomAnchor)
        ])
    }
}

You can also specify the version of Boost that you would like CMake to use by passing -DBOOST_INCLUDEDIR or -DBOOST_ROOT pointing to the location of correct version boost headers

Example:

cmake -DBOOST_ROOT=/opt/latestboost

This will also be useful when multiple boost versions are on the same system.

Inserting data into the middle of a text file is not a simple task. If possible, you should append it to the end of your file.

The easiest way to append data some text file is to use build-in fs.appendFile(filename, data[, options], callback) function from fs module:

var fs = require('fs')
fs.appendFile('log.txt', 'new data', function (err) {
  if (err) {
    // append failed
  } else {
    // done
  }
})

But if you want to write data to log file several times, then it'll be best to use fs.createWriteStream(path[, options]) function instead:

var fs = require('fs')
var logger = fs.createWriteStream('log.txt', {
  flags: 'a' // 'a' means appending (old data will be preserved)
})

logger.write('some data') // append string to your file
logger.write('more data') // again
logger.write('and more') // again

Node will keep appending new data to your file every time you'll call .write, until your application will be closed, or until you'll manually close the stream calling .end:

logger.end() // close string

You need use Stream to send file (archive) in a response, what is more you have to use appropriate Content-type in your response header.

There is an example function that do it:

const fs = require('fs');

// Where fileName is name of the file and response is Node.js Reponse. 
responseFile = (fileName, response) => {
  const filePath =  "/path/to/archive.rar" // or any file format

  // Check if file specified by the filePath exists 
  fs.exists(filePath, function(exists){
      if (exists) {     
        // Content-type is very interesting part that guarantee that
        // Web browser will handle response in an appropriate manner.
        response.writeHead(200, {
          "Content-Type": "application/octet-stream",
          "Content-Disposition": "attachment; filename=" + fileName
        });
        fs.createReadStream(filePath).pipe(response);
      } else {
        response.writeHead(400, {"Content-Type": "text/plain"});
        response.end("ERROR File does not exist");
      }
    });
  }
}

The purpose of the Content-Type field is to describe the data contained in the body fully enough that the receiving user agent can pick an appropriate agent or mechanism to present the data to the user, or otherwise deal with the data in an appropriate manner.

"application/octet-stream" is defined as "arbitrary binary data" in RFC 2046, purpose of this content-type is to be saved to disk - it is what you really need.

"filename=[name of file]" specifies name of file which will be downloaded.

A quick guess if you post your code can say for sure but you might have done something along the lines of

HashMap<String, Object> test = new HashMap();

which will produce the warning when you need to do

HashMap<String, Object> test = new HashMap<String, Object>();

it might be worth looking at

If you close the main Activity using Activity.finish(), I think it will close all the activities. MAybe you can override the default function, and implement it in a static way, I'm not sure

Neither of these answers get to the core reason refresh tokens exist. Obviously, you can always get a new access-token/refresh-token pair by sending your client credentials to the auth server - that's how you get them in the first place.

So the sole purpose of the refresh token is to limit the use of the client credentials being sent over the wire to the auth service. The shorter the TTL of the access-token, the more often the client credentials will have to be used to obtain a new access-token, and therefore the more opportunities attackers have to compromise the client credentials (although this may be super difficult anyway if asymmetric encryption is being used to send them). So if you have a single-use refresh-token, you can make the TTL of access-tokens arbitrarily small without compromising the client credentials.

From the update 2 and after narrowing down the problem scope, we can easily find that there is a brace missing at the end of the function addWord. The compiler will never explicitly identify such a syntax error. instead, it will assume that the missing function definition located in some other object file. The linker will complain about it and hence directly will be categorized under one of the broad the error phrases which is identifier is undefined. Reasonably, because with the current syntax the next function definition (in this case is ac_search) will be included under the addWord scope. Hence, it is not a global function anymore. And that is why compiler will not see this function outside addWord and will throw this error message stating that there is no such a function. A very good elaboration about the compiler and the linker can be found in this article

One often-overlooked advantage of calloc is that (conformant implementations of) it will help protect you against integer overflow vulnerabilities. Compare:

size_t count = get_int32(file);
struct foo *bar = malloc(count * sizeof *bar);

vs.

size_t count = get_int32(file);
struct foo *bar = calloc(count, sizeof *bar);

The former could result in a tiny allocation and subsequent buffer overflows, if count is greater than SIZE_MAX/sizeof *bar. The latter will automatically fail in this case since an object that large cannot be created.

Of course you may have to be on the lookout for non-conformant implementations which simply ignore the possibility of overflow... If this is a concern on platforms you target, you'll have to do a manual test for overflow anyway.

I see several answers here, but they don't seem to address the question - the user wants to get Unicode input from the command line.

Windows uses UTF-16 for encoding in two byte strings, so you need to get these from the OS in your program. There are two ways to do this -

1) Microsoft has an extension that allows main to take a wide character array: int wmain(int argc, wchar_t *argv[]); https://msdn.microsoft.com/en-us/library/6wd819wh.aspx

2) Call the windows api to get the unicode version of the command line wchar_t win_argv = (wchar_t)CommandLineToArgvW(GetCommandLineW(), &nargs); https://docs.microsoft.com/en-us/windows/desktop/api/shellapi/nf-shellapi-commandlinetoargvw

Sure, just do

```{r someVar, echo=FALSE}
someVariable
```

to show some (previously computed) variable someVariable. Or run code that prints etc pp.

So for plotting, I have eg

### Impact of choice of ....
```{r somePlot, echo=FALSE}
plotResults(Res, Grid, "some text", "some more text")
```

where the plotting function plotResults is from a local package.

After integrating Spring 4 with Hibernate 5 in my project and experiencing this problem, I found that I could prevent the error from appearing by changing the way of getting the session from sessionFactory.openSession() to sessionFactory.getCurrentSession(). the proper way to work out this bug may be keep using the same session for the binding transaction.opensession will always create a new session which doesnt like the former one holding a transaction configed.using getCurrentSession and adding additional property <property name="current_session_context_class">org.springframework.orm.hibernate5.SpringSessionContext</property> works fine for me.

The generally-preferred code for 10.5+/iOS.

for (id object in array) {
    // do something with object
}

This construct is used to enumerate objects in a collection which conforms to the NSFastEnumeration protocol. This approach has a speed advantage because it stores pointers to several objects (obtained via a single method call) in a buffer and iterates through them by advancing through the buffer using pointer arithmetic. This is much faster than calling -objectAtIndex: each time through the loop.

It's also worth noting that while you technically can use a for-in loop to step through an NSEnumerator, I have found that this nullifies virtually all of the speed advantage of fast enumeration. The reason is that the default NSEnumerator implementation of -countByEnumeratingWithState:objects:count: places only one object in the buffer on each call.

I reported this in radar://6296108 (Fast enumeration of NSEnumerators is sluggish) but it was returned as Not To Be Fixed. The reason is that fast enumeration pre-fetches a group of objects, and if you want to enumerate only to a given point in the enumerator (e.g. until a particular object is found, or condition is met) and use the same enumerator after breaking out of the loop, it would often be the case that several objects would be skipped.

If you are coding for OS X 10.6 / iOS 4.0 and above, you also have the option of using block-based APIs to enumerate arrays and other collections:

[array enumerateObjectsUsingBlock:^(id object, NSUInteger idx, BOOL *stop) {
    // do something with object
}];

You can also use -enumerateObjectsWithOptions:usingBlock: and pass NSEnumerationConcurrent and/or NSEnumerationReverse as the options argument.

10.4 or earlier

The standard idiom for pre-10.5 is to use an NSEnumerator and a while loop, like so:

NSEnumerator *e = [array objectEnumerator];
id object;
while (object = [e nextObject]) {
  // do something with object
}

I recommend keeping it simple. Tying yourself to an array type is inflexible, and the purported speed increase of using -objectAtIndex: is insignificant to the improvement with fast enumeration on 10.5+ anyway. (Fast enumeration actually uses pointer arithmetic on the underlying data structure, and removes most of the method call overhead.) Premature optimization is never a good idea — it results in messier code to solve a problem that isn't your bottleneck anyway.

When using -objectEnumerator, you very easily change to another enumerable collection (like an NSSet, keys in an NSDictionary, etc.), or even switch to -reverseObjectEnumerator to enumerate an array backwards, all with no other code changes. If the iteration code is in a method, you could even pass in any NSEnumerator and the code doesn't even have to care about what it's iterating. Further, an NSEnumerator (at least those provided by Apple code) retains the collection it's enumerating as long as there are more objects, so you don't have to worry about how long an autoreleased object will exist.

Perhaps the biggest thing an NSEnumerator (or fast enumeration) protects you from is having a mutable collection (array or otherwise) change underneath you without your knowledge while you're enumerating it. If you access the objects by index, you can run into strange exceptions or off-by-one errors (often long after the problem has occurred) that can be horrific to debug. Enumeration using one of the standard idioms has a "fail-fast" behavior, so the problem (caused by incorrect code) will manifest itself immediately when you try to access the next object after the mutation has occurred. As programs get more complex and multi-threaded, or even depend on something that third-party code may modify, fragile enumeration code becomes increasingly problematic. Encapsulation and abstraction FTW! :-)

joaquin's answer works, but has the side effect of removing ticks from the left side of the axes. To fix this, follow up tick_right() with a call to set_ticks_position('both'). A revised example:

from matplotlib import pyplot as plt

f = plt.figure()
ax = f.add_subplot(111)
ax.yaxis.tick_right()
ax.yaxis.set_ticks_position('both')
plt.plot([2,3,4,5])
plt.show()

The result is a plot with ticks on both sides, but tick labels on the right.

There are a few ways to do this.

You could use type="number":

<input type="number" />

Alternatively - I created a reuseable directive for this that uses a regular expression.

Html

<div ng-app="myawesomeapp">
    test: <input restrict-input="^[0-9-]*$" maxlength="20" type="text" class="test" />
</div>

Javascript

;(function(){
    var app = angular.module('myawesomeapp',[])
    .directive('restrictInput', [function(){

        return {
            restrict: 'A',
            link: function (scope, element, attrs) {
                var ele = element[0];
                var regex = RegExp(attrs.restrictInput);
                var value = ele.value;

                ele.addEventListener('keyup',function(e){
                    if (regex.test(ele.value)){
                        value = ele.value;
                    }else{
                        ele.value = value;
                    }
                });
            }
        };
    }]);    
}());

when a developer use an initializer block, the Java Compiler copies the initializer into each constructor of the current class.

Example:

the following code:

class MyClass {

    private int myField = 3;
    {
        myField = myField + 2;
        //myField is worth 5 for all instance
    }

    public MyClass() {
        myField = myField * 4;
        //myField is worth 20 for all instance initialized with this construtor
    }

    public MyClass(int _myParam) {
        if (_myParam > 0) {
            myField = myField * 4;
            //myField is worth 20 for all instance initialized with this construtor
            //if _myParam is greater than 0
        } else {
            myField = myField + 5;
            //myField is worth 10 for all instance initialized with this construtor
            //if _myParam is lower than 0 or if _myParam is worth 0
        }
    }

    public void setMyField(int _myField) {
        myField = _myField;
    }


    public int getMyField() {
        return myField;
    }
}

public class MainClass{

    public static void main(String[] args) {
        MyClass myFirstInstance_ = new MyClass();
        System.out.println(myFirstInstance_.getMyField());//20
        MyClass mySecondInstance_ = new MyClass(1);
        System.out.println(mySecondInstance_.getMyField());//20
        MyClass myThirdInstance_ = new MyClass(-1);
        System.out.println(myThirdInstance_.getMyField());//10
    }
}

is equivalent to:

class MyClass {

    private int myField = 3;

    public MyClass() {
        myField = myField + 2;
        myField = myField * 4;
        //myField is worth 20 for all instance initialized with this construtor
    }

    public MyClass(int _myParam) {
        myField = myField + 2;
        if (_myParam > 0) {
            myField = myField * 4;
            //myField is worth 20 for all instance initialized with this construtor
            //if _myParam is greater than 0
        } else {
            myField = myField + 5;
            //myField is worth 10 for all instance initialized with this construtor
            //if _myParam is lower than 0 or if _myParam is worth 0
        }
    }

    public void setMyField(int _myField) {
        myField = _myField;
    }


    public int getMyField() {
        return myField;
    }
}

public class MainClass{

    public static void main(String[] args) {
        MyClass myFirstInstance_ = new MyClass();
        System.out.println(myFirstInstance_.getMyField());//20
        MyClass mySecondInstance_ = new MyClass(1);
        System.out.println(mySecondInstance_.getMyField());//20
        MyClass myThirdInstance_ = new MyClass(-1);
        System.out.println(myThirdInstance_.getMyField());//10
    }
}

I hope my example is understood by developers.

Fundamentally you hadn't declare location which is what nginx uses to bind URL with resources.

 server {
            listen       80;
            server_name  localhost;

            access_log  logs/localhost.access.log  main;

            location / {
                root /var/www/board/public;
                index index.html index.htm index.php;
            }
       }

Replacing single quotes:

function JavaScriptEncode(text){
    text = text.replace(/'/g,''')
    // More encode here if required

    return text;
}

For me (selectionChange) and the suggested (onSelectionChange) didn't work and I'm not using ReactiveForms. What I ended up doing was using the (valueChange) event like:

<mat-select (valueChange)="someFunction()">

And this worked for me

The easiest way is to use to_datetime:

df['col'] = pd.to_datetime(df['col'])

It also offers a dayfirst argument for European times (but beware this isn't strict).

Here it is in action:

In [11]: pd.to_datetime(pd.Series(['05/23/2005']))
Out[11]:
0   2005-05-23 00:00:00
dtype: datetime64[ns]

You can pass a specific format:

In [12]: pd.to_datetime(pd.Series(['05/23/2005']), format="%m/%d/%Y")
Out[12]:
0   2005-05-23
dtype: datetime64[ns]

select * from table where value % 2 = 1 works fine in mysql.

The Arrays class has versions of sort() and binarySearch() which don't require a Comparator. For example, you can use the version of Arrays.sort() which just takes an array of objects. These methods call the compareTo() method of the objects in the array.

Drew Sherman's solution is very good, but the list must be contiguous (he suggests manually sorting, and that is not acceptable for me). Guitarthrower's solution is kinda slow if the number of items is large and don't respects the order of the original list: it outputs a sorted list regardless.

I wanted the original order of the items (that were sorted by the date in another column), and additionally I wanted to exclude an item from the final list not only if it was duplicated, but also for a variety of other reasons.

My solution is an improvement on Drew Sherman's solution. Likewise, this solution uses 2 columns for intermediate calculations:

Column A:

The list with duplicates and maybe blanks that you want to filter. I will position it in the A11:A1100 interval as an example, because I had trouble moving the Drew Sherman's solution to situations where it didn't start in the first line.

Column B:

This formula will output 0 if the value in this line is valid (contains a non-duplicated value). Note that you can add any other exclusion conditions that you want in the first IF, or as yet another outer IF.

=IF(ISBLANK(A11);1;IF(COUNTIF($A$11:A11;A11)=1;0;COUNTIF($A11:A$1100;A11)))

Use smart copy to populate the column.

Column C:

In the first line we will find the first valid line:

=MATCH(0;B11:B1100;0)

From that position, we search for the next valid value with the following formula:

=C11+MATCH(0;OFFSET($B$11:$B$1100;C11;0);0)

Put it in the second line and use smart copy to fill the rest of the column. This formula will output #N/D error when there is no more unique itens to point. We will take advantage of this in the next column.

Column D:

Now we just have to get the values pointed by column C:

=IFERROR(INDEX($A$11:$A$1100; C11); "")

Use smart copy to populate the column. This is the output unique list.

I had the same problem but it had nothing to do with annotations. The problem happened while indexing beans in my container (Jboss EAP 6.3). One of my beans could not be indexed because it used Java 8 features an I got this sneaky little warning while deploying:

WARN [org.jboss.as.server.deployment] ... Could not index class ... java.lang.IllegalStateException: Unknown tag! pos=20 poolCount = 133

Then at the injection point I got the error:

Unsatisfied dependencies for type ... with qualifiers @Default

The solution is to update the Java annotations index. download new version of jandex (jandex-1.2.3.Final or newer) then put it into

JBOSS_HOME\modules\system\layers\base\org\jboss\jandex\main and then update reference to the new file in module.xml

NOTE: EAP 6.4.x already have this fixed

Unfortunately, Date object in javascript returns information about months only in numeric format. The faster thing you can do is to create an array of months (they are not supposed to change frequently!) and create a function which returns the name based on the number.

Something like this:

function getMonthNameByMonthNumber(mm) { 
   var months = new Array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"); 

   return months[mm]; 
}

Your code therefore becomes:

var prnDt = "Printed on Thursday, " + now.getDate() + " " + getMonthNameByMonthNumber(now.getMonth) + " "+  now.getFullYear() + " at " + h + ":" + m + ":" s;

In my case:

PHImageRequestOptions *requestOptions = [PHImageRequestOptions new];
requestOptions.synchronous            = NO;

Was trying to do this with dispatch_group

ES6 version:

const angleInRadians = angleInDegrees => (angleInDegrees - 90) * (Math.PI / 180.0);

const polarToCartesian = (centerX, centerY, radius, angleInDegrees) => {
    const a = angleInRadians(angleInDegrees);
    return {
        x: centerX + (radius * Math.cos(a)),
        y: centerY + (radius * Math.sin(a)),
    };
};

const arc = (x, y, radius, startAngle, endAngle) => {
    const fullCircle = endAngle - startAngle === 360;
    const start = polarToCartesian(x, y, radius, endAngle - 0.01);
    const end = polarToCartesian(x, y, radius, startAngle);
    const arcSweep = endAngle - startAngle <= 180 ? '0' : '1';

    const d = [
        'M', start.x, start.y,
        'A', radius, radius, 0, arcSweep, 0, end.x, end.y,
    ].join(' ');

    if (fullCircle) d.push('z');
    return d;
};

Either use one of the standard date and time format strings which only specifies the date (e.g. "D" or "d"), or a custom date and time format string which only uses the date parts (e.g. "yyyy/MM/dd").

use EndDialog instead of sending WM_CLOSE:

[DllImport("user32.dll")]
public static extern int EndDialog(IntPtr hDlg, IntPtr nResult);

The cmdlets in PowerShell are very nice and work reliably. Their object-orientedness appeals to me a lot since I'm a Java/C# developer, but it's not at all a complete set. Since it's object oriented, it's missed out on a lot of the text stream maturity of the POSIX tool set (awk and sed to name a few).

The best answer I've found to the dilemma of loving OO techniques and loving the maturity in the POSIX tools is to use both! One great aspect of PowerShell is that it does an excellent job piping objects to standard streams. PowerShell by default uses an object pipeline to transport its objects around. These aren't the standard streams (standard out, standard error, and standard in). When PowerShell needs to pass output to a standard process that doesn't have an object pipeline, it first converts the objects to a text stream. Since it does this so well, PowerShell makes an excellent place to host POSIX tools!

The best POSIX tool set is GnuWin32. It does take more than 5 seconds to install, but it's worth the trouble, and as far as I can tell, it doesn't modify your system (registry, c:\windows\* folders, etc.) except copying files to the directories you specify. This is extra nice because if you put the tools in a shared directory, many people can access them concurrently.

GnuWin32 Installation Instructions

Download and execute the exe (it's from the SourceForge site) pointing it to a suitable directory (I'll be using C:\bin). It will create a GetGnuWin32 directory there in which you will run download.bat, then install.bat (without parameters), after which, there will be a C:\bin\GetGnuWin32\gnuwin32\bin directory that is the most useful folder that has ever existed on a Windows machine. Add that directory to your path, and you're ready to go.

So I experienced this yesterday (22 feb '17), I tried uploading the build via Xcode (8.2) multiple times, it showed (Processing). Then I tried it with the application loader, still the same. I just had to wait for ~12 hours to have it spam me with processing done emails.

So yeah, it's not you, it's them.

You should check it against null.

If you want to check if object x is null or not, you can do:

    if(x != null)

But if it is not null, it can have properties which are null or empty. You will check those explicitly:

    if(x.getProperty() != null)

For "empty" check, it depends on what type is involved. For a Java String, you usually do:

    if(str != null && !str.isEmpty())

As you haven't mentioned about any specific problem with this, difficult to tell.

To find distinct in field_1 in collection but we want some WHERE condition too than we can do like following :

db.your_collection_name.distinct('field_1', {WHERE condition here and it should return a document})

So, find number distinct names from a collection where age > 25 will be like :

db.your_collection_name.distinct('names', {'age': {"$gt": 25}})

Hope it helps!

Another option for in a bash script:

mailbody="Testmail via bash script"
echo "From: [email protected]" > /tmp/mailtest
echo "To: [email protected]" >> /tmp/mailtest
echo "Subject: Mailtest subject" >> /tmp/mailtest
echo "" >> /tmp/mailtest
echo $mailbody >> /tmp/mailtest
cat /tmp/mailtest | /usr/sbin/sendmail -t

• The file /tmp/mailtest is overwritten everytime this script is used.
• The location of sendmail may differ per system.
• When using this in a cron script, you have to use the absolute path for the sendmail command.

You can also convert that attribute as case sensitive using this syntax :

ALTER TABLE Table1
ALTER COLUMN Column1 VARCHAR(200)
COLLATE SQL_Latin1_General_CP1_CS_AS

Now your search will be case sensitive.

If you want to make that column case insensitive again, then use

ALTER TABLE Table1
ALTER COLUMN Column1 VARCHAR(200)
COLLATE SQL_Latin1_General_CP1_CI_AS

Try:

.bottom {
    position: fixed;
    bottom: 0;
}

Just an update because I was trying it on Windows 10 you do need to set the path to the following: ;C:\Program Files\PostgreSQL\9.5\bin ;C:\Program Files\PostgreSQL\9.5\lib

You can do that either through the CMD by using set PATH [the path] or from my

computer => properties => advanced system settings=> Environment Variables => System Variables

Then search for path.

Important: don't replace the PATHs that are already there just add one beside them as follows ;C:\Program Files\PostgreSQL\9.5\bin ;C:\Program Files\PostgreSQL\9.5\lib

Please note: On windows 10, if you follow this: computer => properties => advanced system settings=> Environment Variables => System Variables> select PATH, you actually get the option to add new row. Click Edit, add the /bin and /lib folder locations and save changes.

Then close your command prompt if it's open and then start it again try psql --version If it gives you an answer then you are good to go if not try echo %PATH% and see if the path you set was added or not and if it's added is it added correctly or not.

Not everything works for content type application/json.

If you are using Ext JS form submit to upload file, be aware that the server response is parsed by the browser to create the document for the <iframe>.

If the server is using JSON to send the return object, then the Content-Type header must be set to text/html in order to tell the browser to insert the text unchanged into the document body.

See the Ext JS 3.4.0 API documentation.

Where is your problem??

For the stored procedure, just create:

CREATE PROCEDURE dbo.ReadEmployees @EmpID INT
AS
   SELECT *  -- I would *strongly* recommend specifying the columns EXPLICITLY
   FROM dbo.Emp
   WHERE ID = @EmpID

That's all there is.

From your ASP.NET application, just create a SqlConnection and a SqlCommand (don't forget to set the CommandType = CommandType.StoredProcedure)

DataTable tblEmployees = new DataTable();

using(SqlConnection _con = new SqlConnection("your-connection-string-here"))
using(SqlCommand _cmd = new SqlCommand("ReadEmployees", _con))
{
    _cmd.CommandType = CommandType.StoredProcedure;

    _cmd.Parameters.Add(new SqlParameter("@EmpID", SqlDbType.Int));
    _cmd.Parameters["@EmpID"].Value = 42;

    SqlDataAdapter _dap = new SqlDataAdapter(_cmd);

    _dap.Fill(tblEmployees);
}

YourGridView.DataSource = tblEmployees;
YourGridView.DataBind();

and then fill e.g. a DataTable with that data and bind it to e.g. a GridView.

"But the thing is I also want to be able to add textboxes etc in this popup window thru the form designer."

It's unclear from your description at what stage in the development process you're in. If you haven't already figured it out, to create a new Form you click on Project --> Add Windows Form, then type in a name for the form and hit the "Add" button. Now you can add controls to your form as you'd expect.

When it comes time to display it, follow the advice of the other posts to create an instance and call Show() or ShowDialog() as appropriate.

:g/xxxx/d

This will delete all the lines with pattern, and report how many deleted. Undo to get them back after.

this will work ,simple and easy

 `<form method="POST">
<input  type="submit" onclick="myFunction()" class="save" value="send" name="send" id="send" style="width:20%;">
</form>
<script language ="javascript" >
function myFunction() {
setInterval(function() {document.getElementById("send").click();}, 10000);    
}
</script>

`

Another way to navigate to the location of a function definition would be to break in debugger somewhere you can access the function and enter the functions fully qualified name in the console. This will print the function definition in the console and give a link which on click opens the script location where the function is defined.

32-bit builds of PHP:

• Integers can be from -2,147,483,648 to 2,147,483,647 (~ ± 2 billion)

64-bit builds of PHP:

• Integers can be from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 (~ ± 9 quintillion)

Numbers are inclusive.

Note: some 64-bit builds once used 32-bit integers, particularly older Windows builds of PHP

Values outside of these ranges are represented by floating point values, as are non-integer values within these ranges. The interpreter will automatically determine when this switch to floating point needs to happen based on whether the result value of a calculation can't be represented as an integer.

PHP has no support for "unsigned" integers as such, limiting the maximum value of all integers to the range of a "signed" integer.

fileExists() is a method of FileSystemObject, not a global scope function.

You also have an issue with the delete, DeleteFile() is also a method of FileSystemObject.

Furthermore, it seems you are moving the file and then attempting to deal with the overwrite issue, which is out of order. First you must detect the name collision, so you can choose the rename the file or delete the collision first. I am assuming for some reason you want to keep deleting the new files until you get to the last one, which seemed implied in your question.

So you could use the block:

if NOT fso.FileExists(newname) Then  

    file.move fso.buildpath(OUT_PATH, newname)           

else

    fso.DeleteFile newname
    file.move fso.buildpath(OUT_PATH, newname)  

end if 

Also be careful that your string comparison with the = sign is case sensitive. Use strCmp with vbText compare option for case insensitive string comparison.

And if you need to do it on items that match a specific condition...

double total = myList.Where(item => item.Name == "Eggs").Sum(item => item.Amount);

Allowed only characters & spaces. Ex : Jayant Lonari

if (!/^[a-zA-Z\s]+$/.test(NAME)) {
    //Throw Error
}

If you want to instantiate and add in the same line, you'd have to do something like this:

lstemail.Add(new EmailData { FirstName = "JOhn", LastName = "Smith", Location = "Los Angeles" });

or just instantiate the object prior, and add it directly in:

EmailData data = new EmailData();
data.FirstName = "JOhn";
data.LastName = "Smith";
data.Location = "Los Angeles"

lstemail.Add(data);

As of HTML5 browsers one can use inputElement.form - the value of the attribute must be an id of a <form> element in the same document. More info on MDN.

You can use QString.arg like this

QString my_formatted_string = QString("%1/%2-%3.txt").arg("~", "Tom", "Jane");
// You get "~/Tom-Jane.txt"

This method is preferred over sprintf because:

Changing the position of the string without having to change the ordering of substitution, e.g.

// To get "~/Jane-Tom.txt"
QString my_formatted_string = QString("%1/%3-%2.txt").arg("~", "Tom", "Jane");

Or, changing the type of the arguments doesn't require changing the format string, e.g.

// To get "~/Tom-1.txt"
QString my_formatted_string = QString("%1/%2-%3.txt").arg("~", "Tom", QString::number(1));

As you can see, the change is minimal. Of course, you generally do not need to care about the type that is passed into QString::arg() since most types are correctly overloaded.

One drawback though: QString::arg() doesn't handle std::string. You will need to call: QString::fromStdString() on your std::string to make it into a QString before passing it to QString::arg(). Try to separate the classes that use QString from the classes that use std::string. Or if you can, switch to QString altogether.

ENABLEDELAYEDEXPANSION is a parameter passed to the SETLOCAL command (look at setlocal /?)

Its effect lives for the duration of the script, or an ENDLOCAL:

When the end of a batch script is reached, an implied ENDLOCAL is executed for any outstanding SETLOCAL commands issued by that batch script.

In particular, this means that if you use SETLOCAL ENABLEDELAYEDEXPANSION in a script, any environment variable changes are lost at the end of it unless you take special measures.

That is the HTML code. Anyone can use this:

Just delete the Github repo and create a new one. By far the fastest, easiest and safest approach. After all, what do you have to gain carrying out all those commands in the accepted solution when all you want is the master branch with a single commit?

@dynamic is typically used (as has been said above) when a property is being dynamically created at runtime. NSManagedObject does this (why all its properties are dynamic) -- which suppresses some compiler warnings.

For a good overview on how to create properties dynamically (without NSManagedObject and CoreData:, see: http://developer.apple.com/library/ios/#documentation/Cocoa/Conceptual/ObjCRuntimeGuide/Articles/ocrtDynamicResolution.html#//apple_ref/doc/uid/TP40008048-CH102-SW1

Here is how to use this in your program:

public static void main(String args[])
{
    int [] array = new int[10];

    array[0] = ((int)(Math.random()*100+1));
    array[1] = ((int)(Math.random()*100+1));
    array[2] = ((int)(Math.random()*100+1));
    array[3] = ((int)(Math.random()*100+1));
    array[4] = ((int)(Math.random()*100+1));
    array[5] = ((int)(Math.random()*100+1));
    array[6] = ((int)(Math.random()*100+1));
    array[7] = ((int)(Math.random()*100+1));
    array[8] = ((int)(Math.random()*100+1));
    array[9] = ((int)(Math.random()*100+1));

    Arrays.sort(array); 

    System.out.println(array[0] +" " + array[1] +" " + array[2] +" " + array[3]
    +" " + array[4] +" " + array[5]+" " + array[6]+" " + array[7]+" " 
    + array[8]+" " + array[9] );        

}

Jupyter under the WinPython environment has a batch file in the scripts folder called:

make_working_directory_be_not_winpython.bat

You need to edit the following line in it:

echo WINPYWORKDIR = %%HOMEDRIVE%%%%HOMEPATH%%\Documents\WinPython%%WINPYVER%%\Notebooks>>"%winpython_ini%"

replacing the Documents\WinPython%%WINPYVER%%\Notebooks part with your folder address.

Notice that the %%HOMEDRIVE%%%%HOMEPATH%%\ part will identify the root and user folders (i.e. C:\Users\your_name\) which will allow you to point different WinPython installations on separate computers to the same cloud storage folder (e.g. OneDrive), accessing and working with the same files from different machines. I find that very useful.

Number Of Months When Day & Time Doesn't Matter

In this case, I'm not concerned with full months, part months, how long a month is, etc. I just need to know the number of months. A relevant real world case would be where a report is due every month, and I need to know how many reports there should be.

Example:

• January = 1 month
• January - February = 2 months
• November - January = 3 months

This is an elaborated code example to show where the numbers are going.

Let's take 2 timestamps that should result in 4 months

• November 13, 2019's timestamp: 1573621200000
• February 20, 2020's timestamp: 1582261140000

May be slightly different with your timezone / time pulled. The day, minutes, and seconds don't matter and can be included in the timestamp, but we will disregard it with our actual calculation.

Step 1: convert the timestamp to a JavaScript date

let dateRangeStartConverted = new Date(1573621200000);
let dateRangeEndConverted = new Date(1582261140000);

Step 2: get integer values for the months / years

let startingMonth = dateRangeStartConverted.getMonth();
let startingYear = dateRangeStartConverted.getFullYear();
let endingMonth = dateRangeEndConverted.getMonth();
let endingYear = dateRangeEndConverted.getFullYear();

This gives us

• Starting month: 11
• Starting Year: 2019
• Ending month: 2
• Ending Year: 2020

Step 3: Add (12 * (endYear - startYear)) + 1 to the ending month.

• This makes our starting month stay at 11
• This makes our ending month equal 15 2 + (12 * (2020 - 2019)) + 1 = 15

Step 4: Subtract the months

15 - 11 = 4; we get our 4 month result.

29 Month Example Example

November 2019 through March 2022 is 29 months. If you put these into an excel spreadsheet, you will see 29 rows.

• Our starting month is 11
• Our ending month is 40 3 + (12 * (2022-2019)) + 1

40 - 11 = 29

Use the CX register to count the loops

mov cx, 3
startloop:
   cmp cx, 0
   jz endofloop
   push cx
loopy:
   Call ClrScr
   pop cx
   dec cx
   jmp startloop
endofloop:
   ; Loop ended
   ; Do what ever you have to do here

This simply loops around 3 times calling ClrScr, pushing the CX register onto the stack, comparing to 0, jumping if ZeroFlag is set then jump to endofloop. Notice how the contents of CX is pushed/popped on/off the stack to maintain the flow of the loop.

This is Web GUI of a GitHub repository:

Drag and drop your folder to the above area. When you upload too much folder/files, GitHub will notice you:

Yowza, that’s a lot of files. Try again with fewer than 100 files.

and add commit message

And press button Commit changes is the last step.

Syntax always gets me.... so...

Here is explicitly how to add a line to a batch file that will kill a remote service (on another machine) if you are an admin on both machines, run the .bat as an administrator, and the machines are on the same domain. The machine name follows the UNC format \myserver

sc \\ip.ip.ip.ip stop p4_1

In this case... p4_1 was both the Service Name and the Display Name, when you view the Properties for the service in Service Manager. You must use the Service Name.

For your Service Ops junkies... be sure to append your reason code and comment! i.e. '4' which equals 'Planned' and comment 'Stopping server for maintenance'

sc \\ip.ip.ip.ip stop p4_1 4 Stopping server for maintenance

Having had a similar itch to scratch (altough only for some files of a given repository) this script proved to be really helpful: git-import

The short version is that it creates patch files of the given file or directory ($object) from the existing repository:

cd old_repo
git format-patch --thread -o "$temp" --root -- "$object"

which then get applied to a new repository:

cd new_repo
git am "$temp"/*.patch 

For details please look up:

• the documented source
• git format-patch
• git am

Turns out the problem was in the permission. I fix it with the following command

sudo chown -R $USER /var/www

Please make sure with the $USER variable. I tested and worked on Ubuntu Distro

SELECT
[DATABASE] = DB_NAME(DBID), 
OPNEDCONNECTIONS =COUNT(DBID),
[USER] =LOGINAME
FROM SYS.SYSPROCESSES
GROUP BY DBID, LOGINAME
ORDER BY DB_NAME(DBID), LOGINAME

for German Layout (Deutsches Layout) the default is:

for line Comment: strg + Numpad(/)

for block Comment: strg+shift+Numpad(/)

You can solve your issue by using the 'contains' function within your Xpath query, as below:

var allElementsWithClassFloat = 
   _doc.DocumentNode.SelectNodes("//*[contains(@class,'float')]")

To reuse this in a function do something similar to the following:

string classToFind = "float";    
var allElementsWithClassFloat = 
   _doc.DocumentNode.SelectNodes(string.Format("//*[contains(@class,'{0}')]", classToFind));

this is how you can create an array of boolean in TS and initialize it with false:

var array: boolean[] = [false, false, false]

or another approach can be:

var array2: Array<boolean> =[false, false, false] 

you can specify the type after the colon which in this case is boolean array

Hello you can access your xampp localhost by

1. Control panel -->
2. windows defender firewall -->
3. Advance setting (on left side) --> Inbound Rules --> New Rule --> Port --> in specific local port write your Apache ports --> next --> next then you can access your localhost by using local PC IP address:

std::list does not provide a search method. You can iterate over the list and check if the element exists or use std::find. But I think for your situation std::set is more preferable. The former will take O(n) time but later will take O(lg(n)) time to search.

You can simply use:

int my_var = 3;
std::set<int> mySet {1, 2, 3, 4};
if(mySet.find(myVar) != mySet.end()){
      //do whatever
}

Go a simple way to do this :-

Created one class to hold following information

• Level (number)
• Url (Url of the site)

Go the list of sites stored on a ArrayList object. And executed following query to sort it in descending order by Level.

var query = from MyClass object in objCollection 
    orderby object.Level descending 
    select object

Once I got the collection sorted in descending order, I wrote following code to get the Object that comes as top row

MyClass topObject = query.FirstRow<MyClass>()

This worked like charm.

A workspace is just a text file with a (.code-workspace) extension. You can look at it by opening it with a text editor. I too was frustrated by the idea of a workspace and how it is implemented in Visual Studio Code. I found a method that suits me.

Start with a single "project" folder.

Open Visual Studio Code and close any open workspaces or files or folders. You should see only "OPEN EDITORS" and "NO FOLDER OPENED" in the EXPLORER.

From the menu bar* → File → Open Folder.... Navigate to where you want to put your folder and right click to open a new folder. Name it whatever you want, then click on "Select Folder". It will appear in the *Visual Studio Code explorer.

Now from menu File → Save Workspace As.... Name the workspace and save it wherever you want to keep all your workspaces, (not necessarily where your project folders are). I put all mine in a folder called "Visual Studio Code workspace".

It will be saved as a (.code-workspace) file and is just an index to all the files and folders it contains (or points to) wherever they may be on your hard drive. You can look at it by opening it with a text editor. Close the folder you created and close Visual Studio Code.

Now find your workspace "file" and double click on it. This will open Visual Studio Code with the folder you created in your workspace. Or you can open Visual Studio Code and use "Open Workspace".

Any folders you create from within your Visual Studio Code workspace will be inside your first folder. If you want to add any more top level folders, create them first wherever you want them and then use "Add To Workspace.." from Visual Studio Code.

1. find($id) takes an id and returns a single model. If no matching model exist, it returns null.

2. findOrFail($id) takes an id and returns a single model. If no matching model exist, it throws an error¹.

3. first() returns the first record found in the database. If no matching model exist, it returns null.

4. firstOrFail() returns the first record found in the database. If no matching model exist, it throws an error¹.

5. get() returns a collection of models matching the query.

6. pluck($column) returns a collection of just the values in the given column. In previous versions of Laravel this method was called lists.

7. toArray() converts the model/collection into a simple PHP array.

Note: a collection is a beefed up array. It functions similarly to an array, but has a lot of added functionality, as you can see in the docs.

Unfortunately, PHP doesn't let you use a collection object everywhere you can use an array. For example, using a collection in a foreach loop is ok, put passing it to array_map is not. Similarly, if you type-hint an argument as array, PHP won't let you pass it a collection. Starting in PHP 7.1, there is the iterable typehint, which can be used to accept both arrays and collections.

If you ever want to get a plain array from a collection, call its all() method.

¹ The error thrown by the findOrFail and firstOrFail methods is a ModelNotFoundException. If you don't catch this exception yourself, Laravel will respond with a 404, which is what you want most of the time.

Here is the sample "Map" implementation in Go. Hope this helps!!

func square(num int) int {
    return num * num
}

func mapper(f func(int) int, alist []int) []int {
    var a = make([]int, len(alist), len(alist))
    for index, val := range alist {

        a[index] = f(val)
    }
    return a
}

func main() {
    alist := []int{4, 5, 6, 7}
    result := mapper(square, alist)
    fmt.Println(result)

}

You can use slice with no arguments to copy an array:

var foo,
    bar;
foo = [3,1,2];
bar = foo.slice().sort();

To escape the backslash, simply use 2 of them, like this: \\

If you need to escape other things, this may be helpful..

SQL Server doesn't have regular expressions. It uses the LIKE pattern matching syntax which isn't the same.

As it happens, you are close. Just need leading+trailing wildcards and move the NOT

 WHERE whatever NOT LIKE '%[a-z0-9]%'

To clarify the last post:

The VBoxManage command is:

VBoxManage setextradata <VM_NAME> VBoxInternal2/SharedFoldersEnableSymlinksCreate/<SHARE_NAME> 1

You're trying to call the isEmpty() method on a null reference (as List test = null; ). This will surely throw a NullPointerException. You should do if(test!=null) instead (Checking for null first).

The method isEmpty() returns true, if an ArrayList object contains no elements; false otherwise (for that the List must first be instantiated that is in your case is null).

Edit:

You may want to see this question.

I am not sure what you need the app/installation ID for, but you can review the existing possibilities in a great article from Android developers:

• http://android-developers.blogspot.com/2011/03/identifying-app-installations.html

To sum up:

• UUID.randomUUID() for creating id on the first time an app runs after installation and simple retrieval afterwards
• TelephonyManager.getDeviceId() for actual device identifier
• Settings.Secure.ANDROID_ID on relatively modern devices

I prefer this solution:

df = spark.table(selected_table).filter(condition)

counter = df.count()

df = df.select([(counter - count(c)).alias(c) for c in df.columns])

In visual studio code i found that simple regex as ^ worked.

Using the second form gives you a variable (named based upon the as clause, in your example e) in the except block scope with the exception object bound to it so you can use the infomration in the exception (type, message, stack trace, etc) to handle the exception in a more specially tailored manor.

In MySQL,

WHERE column_name LIKE '%|%%' ESCAPE '|'

Without using jQuery, only vanilla JavaScript:

var inactivityTime = function () {
    var time;
    window.onload = resetTimer;
    // DOM Events
    document.onmousemove = resetTimer;
    document.onkeypress = resetTimer;

    function logout() {
        alert("You are now logged out.")
        //location.href = 'logout.html'
    }

    function resetTimer() {
        clearTimeout(time);
        time = setTimeout(logout, 3000)
        // 1000 milliseconds = 1 second
    }
};

And init the function where you need it (for example: onPageLoad).

window.onload = function() {
  inactivityTime(); 
}

You can add more DOM events if you need to. Most used are:

document.onload = resetTimer;
document.onmousemove = resetTimer;
document.onmousedown = resetTimer; // touchscreen presses
document.ontouchstart = resetTimer;
document.onclick = resetTimer;     // touchpad clicks
document.onkeydown = resetTimer;   // onkeypress is deprectaed
document.addEventListener('scroll', resetTimer, true); // improved; see comments

Or register desired events using an array

window.addEventListener('load', resetTimer, true);
var events = ['mousedown', 'mousemove', 'keypress', 'scroll', 'touchstart'];
events.forEach(function(name) {
 document.addEventListener(name, resetTimer, true); 
});

DOM Events list: http://www.w3schools.com/jsref/dom_obj_event.asp

Remember use window, or document according your needs. Here you can see the differences between them: What is the difference between window, screen, and document in Javascript?

Code Updated with @frank-conijn and @daxchen improve: window.onscroll will not fire if scrolling is inside a scrollable element, because scroll events don't bubble. window.addEventListener('scroll', resetTimer, true), the third argument tells the listener to catch event during capture phase instead of bubble phase.

"Day of Week" is actually something you can get directly from the php date() function with the format "l" or "N" respectively. Have a look at the manual

edit: Sorry I didn't read the posts of Kalium properly, he already explained that. My bad.

I'd suggest OOWeb to act as an HTTP server and a templating engine like Velocity to generate HTML. I also second Esko's suggestion of Wicket. Both solutions are considerably simpler than the average setup.

I suggest using:

command $(echo $(tr '\n' ' ' < parameters.cfg))

Simply trim the end-line characters and replace them with spaces, and then push the resulting string as possible separate arguments with echo.

Polymorphism is this:

class Cup {
   int capacity
}

class TeaCup : Cup {
   string flavour
}

class CoffeeCup : Cup {
   string brand
}

Cup c = new CoffeeCup();

public int measure(Cup c) {
    return c.capacity
}

you can pass just a Cup instead of a specific instance. This aids in generality because you don't have to provide a specific measure() instance per each cup type

In order to use API tokens, users will have to obtain their own tokens, each from https://<jenkins-server>/me/configure or https://<jenkins-server>/user/<user-name>/configure. It is up to you, as the author of the script, to determine how users supply the token to the script. For example, in a Bourne Shell script running interactively inside a Git repository, where .gitignore contains /.jenkins_api_token, you might do something like:

api_token_file="$(git rev-parse --show-cdup).jenkins_api_token"
api_token=$(cat "$api_token_file" || true)
if [ -z "$api_token" ]; then
    echo
    echo "Obtain your API token from $JENKINS_URL/user/$user/configure"
    echo "After entering here, it will be saved in $api_token_file; keep it safe!"
    read -p "Enter your Jenkins API token: " api_token
    echo $api_token > "$api_token_file"
fi
curl -u $user:$api_token $JENKINS_URL/someCommand

If you want to update your listview doesn't matter if you want to do that on onResume(), onCreate() or in some other function, first thing that you have to realize is that you won't need to create a new instance of the adapter, just populate the arrays with your data again. The idea is something similar to this :

private ArrayList<String> titles;
private MyListAdapter adapter;
private ListView myListView;

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

    myListView = (ListView) findViewById(R.id.my_list);

    titles = new ArrayList<String>()

    for(int i =0; i<20;i++){
        titles.add("Title "+i);
    }

    adapter = new MyListAdapter(this, titles);
    myListView.setAdapter(adapter);
}


@Override
public void onResume(){
    super.onResume();
    // first clear the items and populate the new items
    titles.clear();
    for(int i =0; i<20;i++){
        titles.add("New Title "+i);
    }
    adapter.notifySetDataChanged();
}

So depending on that answer you should use the same List<Item> in your Fragment. In your first adapter initialization you fill your list with the items and set adapter to your listview. After that in every change in your items you have to clear the values from the main List<Item> items and than populate it again with your new items and call notifySetDataChanged();.

That's how it works : ).

Try this

Months.values()[index]

My Table didn't have primary key then I had time out error. after set key sloved.

One tweak to all of these answers:

var routes = fs.readdirSync('routes')
      .filter(function(v){
         return (/.js$/).test(v);
      });

Just use a regex to filter via testing each file in the array. It is not recursive, but it will filter out folders that don't end in .js

I think this will do it:

SELECT * FROM MyTable WHERE mydate > now()::date - 365;

I ran into this problem because one level of tag, <ListView.View> to be specirfic, was missing in my XAML.

This code produced this error.

<Grid>
    <ListView Margin="10" Name="lvDataBinding" >
        <GridView>
            <GridViewColumn Header="Name" Width="120" DisplayMemberBinding="{Binding Name}" />
            <GridViewColumn Header="Age" Width="50" DisplayMemberBinding="{Binding Age}" />
            <GridViewColumn Header="Mail" Width="150" DisplayMemberBinding="{Binding Mail}" />
        </GridView>
    </ListView>
</Grid>

The following fixed it

<Grid>
    <ListView Margin="10" Name="lvDataBinding" >
        <ListView.View> <!-- This was missing in top! -->
            <GridView>
                <GridViewColumn Header="Name" Width="120" DisplayMemberBinding="{Binding Name}" />
                <GridViewColumn Header="Age" Width="50" DisplayMemberBinding="{Binding Age}" />
                <GridViewColumn Header="Mail" Width="150" DisplayMemberBinding="{Binding Mail}" />
            </GridView>
        </ListView.View>
    </ListView>

You're comparing apples to oranges here:

• webHttpBinding is the REST-style binding, where you basically just hit a URL and get back a truckload of XML or JSON from the web service

• basicHttpBinding and wsHttpBinding are two SOAP-based bindings which is quite different from REST. SOAP has the advantage of having WSDL and XSD to describe the service, its methods, and the data being passed around in great detail (REST doesn't have anything like that - yet). On the other hand, you can't just browse to a wsHttpBinding endpoint with your browser and look at XML - you have to use a SOAP client, e.g. the WcfTestClient or your own app.

So your first decision must be: REST vs. SOAP (or you can expose both types of endpoints from your service - that's possible, too).

Then, between basicHttpBinding and wsHttpBinding, there differences are as follows:

• basicHttpBinding is the very basic binding - SOAP 1.1, not much in terms of security, not much else in terms of features - but compatible to just about any SOAP client out there --> great for interoperability, weak on features and security

• wsHttpBinding is the full-blown binding, which supports a ton of WS-* features and standards - it has lots more security features, you can use sessionful connections, you can use reliable messaging, you can use transactional control - just a lot more stuff, but wsHttpBinding is also a lot *heavier" and adds a lot of overhead to your messages as they travel across the network

For an in-depth comparison (including a table and code examples) between the two check out this codeproject article: Differences between BasicHttpBinding and WsHttpBinding

Stored procedure is the best way to do it. Because Meherzad's solution would work only if the data follows the same order.

If we have a table structure like this

col1 | col2 | col3
-----+------+------
 3   | k    | 7
 5   | d    | 3
 1   | a    | 5
 6   | o    | 2
 2   | 0    | 8

It wont work. SQL Fiddle Demo

Here is a sample procedure code to achieve the same.

delimiter //
CREATE PROCEDURE chainReaction 
(
    in inputNo int
) 
BEGIN 
    declare final_id int default NULL;
    SELECT col3 
    INTO final_id 
    FROM table1
    WHERE col1 = inputNo;
    IF( final_id is not null) THEN
        INSERT INTO results(SELECT col1, col2, col3 FROM table1 WHERE col1 = inputNo);
        CALL chainReaction(final_id);   
    end if;
END//
delimiter ;

call chainReaction(1);
SELECT * FROM results;
DROP TABLE if exists results;

C# version of nirg's answer is here: I'll just share the code. It may save someone some time.

public static bool IsPointInPolygon(IList<Point> polygon, Point testPoint) {
            bool result = false;
            int j = polygon.Count() - 1;
            for (int i = 0; i < polygon.Count(); i++) {
                if (polygon[i].Y < testPoint.Y && polygon[j].Y >= testPoint.Y || polygon[j].Y < testPoint.Y && polygon[i].Y >= testPoint.Y) {
                    if (polygon[i].X + (testPoint.Y - polygon[i].Y) / (polygon[j].Y - polygon[i].Y) * (polygon[j].X - polygon[i].X) < testPoint.X) {
                        result = !result;
                    }
                }
                j = i;
            }
            return result;
        }

Size of a pointer should be 8 byte on any 64-bit C/C++ compiler, but not necessarily size of int.

You want to get an element from an empty array. That's why the Size: 0 from the exception

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

So you cant do lstpp.get(0) until you fill the array.

Not currently possible on Github.com or their API-s

I have talked to customer support and confirmed that this can not be done on github.com. They have passed the suggestion along to the Github team though, so hopefully it will be possible in the future. If so, I'll be sure to edit this answer.

Meanwhile, Rory O'Kane's answer is a brilliant alternative based on cloc and a shallow repo clone.

Yes there is a way to do it.

First declare a class.

//anyfile.ts
export class Custom
{
  name: string, 
  empoloyeeID: number
}

Then in your component import the class

import {Custom} from '../path/to/anyfile.ts'
.....
export class FormComponent implements OnInit {
 name: string;
 empoloyeeID : number;
 empList: Array<Custom> = [];
 constructor() {

 }

 ngOnInit() {
 }
 onEmpCreate(){
   //console.log(this.name,this.empoloyeeID);
   let customObj = new Custom();
   customObj.name = "something";
   customObj.employeeId = 12; 
   this.empList.push(customObj);
   this.name ="";
   this.empoloyeeID = 0; 
 }
}

Another way would be to interfaces read the documentation once - https://www.typescriptlang.org/docs/handbook/interfaces.html

Also checkout this question, it is very interesting - When to use Interface and Model in TypeScript / Angular2

It means the connection was successfully established at some point, but when you tried to commit right there, the connection was no longer open. The parameters you mentioned sound like connection pool settings. If so, they're unrelated to this problem. The most likely cause is a firewall between you and the database that is killing connections after a certain amount of idle time. The most common fix is to make your connection pool run a validation query when a connection is checked out from it. This will immediately identify and evict dead connnections, ensuring that you only get good connections out of the pool.

<content>(?:[^\n]*(\n+))+</content>

Another option might be to avoid WCF all-together and just use a .NET HttpHandler. The HttpHandler can grab the query-string variables from your GET and just write back a response to the Java code.

The method cat() of the .str accessor works really well for this:

>>> import pandas as pd
>>> df = pd.DataFrame([["2014", "q1"], 
...                    ["2015", "q3"]],
...                   columns=('Year', 'Quarter'))
>>> print(df)
   Year Quarter
0  2014      q1
1  2015      q3
>>> df['Period'] = df.Year.str.cat(df.Quarter)
>>> print(df)
   Year Quarter  Period
0  2014      q1  2014q1
1  2015      q3  2015q3

cat() even allows you to add a separator so, for example, suppose you only have integers for year and period, you can do this:

>>> import pandas as pd
>>> df = pd.DataFrame([[2014, 1],
...                    [2015, 3]],
...                   columns=('Year', 'Quarter'))
>>> print(df)
   Year Quarter
0  2014       1
1  2015       3
>>> df['Period'] = df.Year.astype(str).str.cat(df.Quarter.astype(str), sep='q')
>>> print(df)
   Year Quarter  Period
0  2014       1  2014q1
1  2015       3  2015q3

Joining multiple columns is just a matter of passing either a list of series or a dataframe containing all but the first column as a parameter to str.cat() invoked on the first column (Series):

>>> df = pd.DataFrame(
...     [['USA', 'Nevada', 'Las Vegas'],
...      ['Brazil', 'Pernambuco', 'Recife']],
...     columns=['Country', 'State', 'City'],
... )
>>> df['AllTogether'] = df['Country'].str.cat(df[['State', 'City']], sep=' - ')
>>> print(df)
  Country       State       City                   AllTogether
0     USA      Nevada  Las Vegas      USA - Nevada - Las Vegas
1  Brazil  Pernambuco     Recife  Brazil - Pernambuco - Recife

Do note that if your pandas dataframe/series has null values, you need to include the parameter na_rep to replace the NaN values with a string, otherwise the combined column will default to NaN.

You can also download psftp.exe from:

http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

When you run it you type:

open "server name"

Then:

put "file name"

(Type help to get a full list of commands.)

You can also type get <file name> to download files from a remote machine to the local machine.

That is quite simpler way to do it:

ls -l | tr -s " " " " | cut -d " " -f 5,9 | sort -n -r | head -n 1***

And you'll get this: 8445 examples.desktop

Seems like just adding meta tags to index.html doesn't prevent page from zooming. Adding below style will do the magic.

:root {
  touch-action: pan-x pan-y;
  height: 100% 
}

EDIT: Demo: https://no-mobile-zoom.stackblitz.io

os.remove() does not work on a directory, and os.rmdir() will only work on an empty directory. And Python won't automatically expand "/home/me/test/*" like some shells do.

You can use shutil.rmtree() on the directory to do this, however.

import shutil
shutil.rmtree('/home/me/test') 

be careful as it removes the files and the sub-directories as well.

You need to either have the message be a fixed size, or you need to send the size or you need to use some separator characters.

This is the easiest case for a known size (100 bytes):

in = new DataInputStream(server.getInputStream());
byte[] message = new byte[100]; // the well known size
in.readFully(message);

In this case DataInputStream makes sense as it offers readFully(). If you don't use it, you need to loop yourself until the expected number of bytes is read.

Given an instance of the struct, you set the values.

    student thisStudent;
    Console.WriteLine("Please enter StudentId, StudentName, CourseName, Date-Of-Birth");
    thisStudent.s_id = int.Parse(Console.ReadLine());
    thisStudent.s_name = Console.ReadLine();
    thisStudent.c_name = Console.ReadLine();
    thisStudent.s_dob = Console.ReadLine();

Note this code is incredibly fragile, since we aren't checking the input from the user at all. And you aren't clear to the user that you expect each data point to be entered on a separate line.

The scrolling effect is cause by specifying the generic 'background' property in your css instead of the more specific background-image. By setting the background property, the animation will transition between all properties.. Background-Color, Background-Image, Background-Position.. Etc Thus causing the scrolling effect..

E.g.

a {
-webkit-transition-property: background-image 300ms ease-in 200ms;
-moz-transition-property: background-image 300ms ease-in 200ms;
-o-transition-property: background-image 300ms ease-in 200ms;
transition: background-image 300ms ease-in 200ms;
}

The way is correct, but can be improved a bit with the extended set-syntax.

set "var=xyz"

Sets the var to the content until the last quotation mark, this ensures that no "hidden" spaces are appended.

Your code would look like

set "var1=A"
set "var2=B"
set "AB=hi"
set "newvar=%var1%%var2%"
echo %newvar% is the concat of var1 and var2
echo !%newvar%! is the indirect content of newvar

You clone a repository with git clone [url]. Like so,

$ git clone https://github.com/libgit2/libgit2

If your div is absolutely positioned and you know the width, you can just use:

#myDiv{
position:absolute;
left: 0;
width: 200px;
}

$('#myDiv').animate({left:'-200'},1000);

Which will slide it off screen.

Alternatively, you could wrap it a container div

#myContainer{
position:relative;
width: 200px;
overflow: hidden;
}

#myDiv{
position:absolute;
top: 0;
left: 0;
width: 200px;
}

<div id="myContainer">

<div id="myDiv">Wheee!</div>

</div>

$('#myDiv').animate({left:'-200'},1000);

I've tried using flask instead of a simple apscheduler what you need to install is

pip3 install flask_apscheduler

Below is the sample of my code:

from flask import Flask
from flask_apscheduler import APScheduler

app = Flask(__name__)
scheduler = APScheduler()

def scheduleTask():
    print("This test runs every 3 seconds")

if __name__ == '__main__':
    scheduler.add_job(id = 'Scheduled Task', func=scheduleTask, trigger="interval", seconds=3)
    scheduler.start()
    app.run(host="0.0.0.0")

Use the RAISERROR function:

RAISERROR( 'This message will show up right away...',0,1) WITH NOWAIT

You shouldn't completely replace all your prints with raiserror. If you have a loop or large cursor somewhere just do it once or twice per iteration or even just every several iterations.

Also: I first learned about RAISERROR at this link, which I now consider the definitive source on SQL Server Error handling and definitely worth a read:
http://www.sommarskog.se/error-handling-I.html

Brighams answer uses literal regexp.

Solution with a Regex object.

var regex = new RegExp('\n', 'g');
text = text.replace(regex, '<br />');

TRY IT HERE : JSFiddle Working Example

This script:

import subprocess
import os
with open(os.devnull, "wb") as limbo:
        for n in xrange(1, 10):
                ip="192.168.0.{0}".format(n)
                result=subprocess.Popen(["ping", "-c", "1", "-n", "-W", "2", ip],
                        stdout=limbo, stderr=limbo).wait()
                if result:
                        print ip, "inactive"
                else:
                        print ip, "active"

will produce something like this output:

192.168.0.1 active
192.168.0.2 active
192.168.0.3 inactive
192.168.0.4 inactive
192.168.0.5 inactive
192.168.0.6 inactive
192.168.0.7 active
192.168.0.8 inactive
192.168.0.9 inactive

You can capture the output if you replace limbo with subprocess.PIPE and use communicate() on the Popen object:

p=Popen( ... )
output=p.communicate()
result=p.wait()

This way you get the return value of the command and can capture the text. Following the manual this is the preferred way to operate a subprocess if you need flexibility:

The underlying process creation and management in this module is handled by the Popen class. It offers a lot of flexibility so that developers are able to handle the less common cases not covered by the convenience functions.

As described here for a post request :

var http = require('http');

var options = {
  host: 'www.host.com',
  path: '/',
  port: '80',
  method: 'POST'
};

callback = function(response) {
  var str = ''
  response.on('data', function (chunk) {
    str += chunk;
  });

  response.on('end', function () {
    console.log(str);
  });
}

var req = http.request(options, callback);
//This is the data we are posting, it needs to be a string or a buffer
req.write("data");
req.end();
