easyest way to redirect http to https in wordpress it to modify site_url and home from http://example.com to https://example.com. Wordpress will do the redirection. ( that is why you get "too many redirects" error, wordpress is redirecting to http while .htaccess will redirect to https )

4 best ways to remove public from the URL.

If you used any other trick to remove the public from the URL like changes the name of server.php to index.php and changing into the core file path. Clearly, don't do that. Then why Laravel not giving the solution like this because it's not a proper way to do that.

1) Remove public from URL using htaccess in Laravel

By adding a .htaccess file into the root, You can access the website without public

<ifmodule mod_rewrite.c>
    <ifmodule mod_negotiation.c>
        Options -MultiViews
    </ifmodule>

    RewriteEngine On

    RewriteCond %{REQUEST_FILENAME} -d [OR]
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule ^ ^$1 [N]

    RewriteCond %{REQUEST_URI} (\.\w+$) [NC]
    RewriteRule ^(.*)$ public/$1 

    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ server.php

</ifmodule>

2) Remove the public by creating a virtual host in your local

I am giving demo here for the Window operating system. But I will try to define a step so that anyone can easily follow the step. You can also research on google for the same for the particular operating system.

Step 1: Go to C:\Windows\system32\drivers\etc\ open the "hosts" file in Administrator mode.

Step 2: Add the following code to it. Here, I am giving you a demo of projectname.local domain name demo, you can specify any as you like. Just make it constant at every place.

127.0.0.1  projectname.local

Step 3: Now go to, C:\xampp\apache\conf\extra for xampp users and for the wamp user "C:\wamp\bin\apache\Apache2.4.4\conf\extra" and open "httpd-vhosts.conf" file. Now add the following code into it.

Notes: Change the Document root as per your project also add domain name as you define into the "hosts" file.

<VirtualHost projectname.local>
      ServerAdmin projectname.local
      DocumentRoot "C:/xampp/htdocs/projectdir"
      ServerName projectname.local
      ErrorLog "logs/projectname.local.log"
      CustomLog "logs/projectname.local.log" common
 </VirtualHost>

Step 4: Last but the important step is to restart your Xampp or Wamp and access the url like http://projectname.local and your Laravel will respond without public URL.

3) Remove the public by running the command in Laravel

If you are working in local then you don't need to do anything just need to run the following command from your terminal or command line tool. After that, you can access your website by provided URL by the command line.

   > php artisan serve

If you are willing to run your project on particular IP then you need to run following command. If you are working on LAN then if you want to allow other people to access your website from local then you just need to check your IP address using command line by running "ipconfig" after getting your IP address run following the command.

> php artisan serve --host=192.168.0.177

If you are willing to run your project on a particular IP with particular port then you need to the following command.

> php artisan serve --host=192.168.0.177 --port=77

4) Remove the public on the hosted server or on the cpanel

After completion of the project you need to host the project on the server, then you just need to set the document root on your domain to the public folder. Check the below screenshot.

As per screenshot if you don't have any project folder into the public_html then you just need to set your document root like "public_html/public".

Reference taken from here

I had same problem and after three hour struggling I find out what's going on

In my case, when I wanted to migrate for the first time in up() method, the default code wants to create the tables that already existed so I got same error as you

To solve it, just delete those code and write want you want. For example, I wanted to add a column so i just write

migrationBuilder.AddColumn<string>(
            name: "fieldName",
            table: "tableName",
            nullable: true);

In my particular case the function was actually missing. The error message is the same. I am using the Postgresql plugin PostGIS and I had to reinstall that for whatever reason.

If you use IIS Windows Server add web.config file in root folder and put the below code :

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="Imported Rule 1" stopProcessing="true">
                    <match url="^(.*)$" ignoreCase="false" />
                    <conditions logicalGrouping="MatchAll">
                        <add input="{URL}" pattern="^system.*" ignoreCase="false" />
                    </conditions>
                    <action type="Rewrite" url="/index.php/{R:1}" />
                </rule>
                <rule name="Imported Rule 2" stopProcessing="true">
                    <match url="^(.*)$" ignoreCase="false" />
                    <conditions logicalGrouping="MatchAll">
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" />
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" />
                        <add input="{R:1}" pattern="^(index\.php|images|robots\.txt|css)" ignoreCase="false" negate="true" />
                    </conditions>
                    <action type="Rewrite" url="index.php/{R:1}" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>

and if you use .htaccess use this one :

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

Try this

Replace

<Directory /usr/share/phpMyAdmin/>
    <IfModule mod_authz_core.c>
        # Apache 2.4
        <RequireAny>
            Require ip 127.0.0.1
            Require ip ::1
        </RequireAny>
    </IfModule>
    <IfModule !mod_authz_core.c>
        # Apache 2.2
        Order Deny,Allow
        Deny from All
        Allow from 127.0.0.1
        Allow from ::1
    </IfModule>
</Directory>

With this:

<Directory "/usr/share/phpMyAdmin/">
    Options Indexes FollowSymLinks MultiViews
    AllowOverride all
        Order Allow,Deny 
    Allow from all
</Directory>

Add the following line for ease of access:

Alias /phpmyadmin /usr/share/phpMyAdmin

None of the configuration above worked for me on my CentOS 7 server. After hours of searching, that what worked for me:

Edit file phpMyAdmin.conf

sudo nano /etc/httpd/conf.d/phpMyAdmin.conf

And replace the existing <Directory> ... </Directory> node with the following:

<Directory /usr/share/phpMyAdmin/>
   AddDefaultCharset UTF-8

   <IfModule mod_authz_core.c>
     # Apache 2.4
     <RequireAny>
       #Require ip 127.0.0.1
       #Require ip ::1
       Require all granted
     </RequireAny>
   </IfModule>
   <IfModule !mod_authz_core.c>
     # Apache 2.2
     Order Deny,Allow
     Deny from All
     Allow from 127.0.0.1
     Allow from ::1
   </IfModule>
</Directory>

You're getting into looping most likely due to these rules:

RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]

Just comment it out and try again in a new browser.

Check this answer: Set CORS header in Tomcat

Note that you need Tomcat 7.0.41 or higher.

To know where the current instance of Tomcat is located try this:

System.out.println(System.getProperty("catalina.base"));

You'll see the path in the console view.

Then look for /conf/web.xml on that folder, open it and add the lines of the above link.

Update for XAMPP 7.3.*

If you get into same problem for phpmyadmin in the newest XAMPP, as I had.

The solution is written inside the official documentation located in [XAMPP IP]/dashboard/docs/access-phpmyadmin-remotely.html

To enable remote access to phpMyAdmin from other hosts, follow these steps:

1. Launch the stack manager by double-clicking the XAMPP icon in the mounted disk image.

2. Ensure that Apache and MySQL services are running in the "Services" tab of the stack manager (or start them as needed).

3. Open a new terminal from the "General" tab of the stack manager.

4. Edit the /opt/lampp/etc/extra/httpd-xampp.conf file.

5. Within this file, find the block <Directory "/opt/lampp/phpmyadmin">

Update this block and replace Require local with Require all granted,

6. Save the file and restart the Apache service using the stack manager.

Note for section (4) To edit this file make sure you have vim installed.

Note for section (5) Instead of allowing access to all, which is highly insecure, if your computer is connected to a network. A safer approach is to limit the access to only set of IPs as suggested by @Gunnar Bernstein.

In my case I did:

<Directory "/opt/lampp/phpmyadmin">
  AllowOverride AuthConfig Limit
  Require local
  Require ip 192.168
  ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

In httpd.conf file you need to remove #

#LoadModule rewrite_module modules/mod_rewrite.so

after removing # line will look like this:

LoadModule rewrite_module modules/mod_rewrite.so

And Apache restart

Got this from the Laravel forums, but if you recently upgraded Laravel versions AND PHP versions AND are running nginx, make sure you have changed your nginx configuration file to reflect the new PHP version. For instance:

In your nginx site config file (here: /etc/nginx/sites-available), change

fastcgi_pass unix:/var/run/php5-fpm.sock;

to

fastcgi_pass unix:/var/run/php/php5.6-fpm.sock;

Your virtualhost filename should be mysite.com.conf and should contain this info

<VirtualHost *:80>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.
    ServerName mysite.com
    ServerAlias www.mysite.com

    ServerAdmin [email protected]
    DocumentRoot /var/www/mysite

    # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
    # error, crit, alert, emerg.
    # It is also possible to configure the loglevel for particular
    # modules, e.g.
    #LogLevel info ssl:warn

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

<Directory "/var/www/mysite">
Options All
AllowOverride All
Require all granted
</Directory>


    # For most configuration files from conf-available/, which are
    # enabled or disabled at a global level, it is possible to
    # include a line for only one particular virtual host. For example the
    # following line enables the CGI configuration for this host only
    # after it has been globally disabled with "a2disconf".
    #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

Here's an approach that could resolve your problem, and if not would help with troubleshooting.

1. Create a second Apache virtual server identical to the current one

2. Send all "normal" user traffic to the original virtual server

3. Send special or long-running traffic to the new virtual server

Special or long-running traffic could be report-generation, maintenance ops or anything else you don't expect to complete in <<1 second. This can happen serving APIs, not just web pages.

If your resource utilization is low but you still exceed MaxClients, the most likely answer is you have new connections arriving faster than they can be serviced. Putting any slow operations on a second virtual server will help prove if this is the case. Use the Apache access logs to quantify the effect.

❐ Using java.sql.Date

If your table has a column of type DATE:

• java.lang.String

  The method java.sql.Date.valueOf(java.lang.String) received a string representing a date in the format yyyy-[m]m-[d]d. e.g.:

  ps.setDate(2, java.sql.Date.valueOf("2013-09-04"));
  

• java.util.Date

  Suppose you have a variable endDate of type java.util.Date, you make the conversion thus:

  ps.setDate(2, new java.sql.Date(endDate.getTime());
  

• Current

  If you want to insert the current date:

  ps.setDate(2, new java.sql.Date(System.currentTimeMillis()));
  
  // Since Java 8
  ps.setDate(2, java.sql.Date.valueOf(java.time.LocalDate.now()));
  

❐ Using java.sql.Timestamp

If your table has a column of type TIMESTAMP or DATETIME:

• java.lang.String

  The method java.sql.Timestamp.valueOf(java.lang.String) received a string representing a date in the format yyyy-[m]m-[d]d hh:mm:ss[.f...]. e.g.:

  ps.setTimestamp(2, java.sql.Timestamp.valueOf("2013-09-04 13:30:00");
  

• java.util.Date

  Suppose you have a variable endDate of type java.util.Date, you make the conversion thus:

  ps.setTimestamp(2, new java.sql.Timestamp(endDate.getTime()));
  

• Current

  If you require the current timestamp:

  ps.setTimestamp(2, new java.sql.Timestamp(System.currentTimeMillis()));
  
  // Since Java 8
  ps.setTimestamp(2, java.sql.Timestamp.from(java.time.Instant.now()));
  ps.setTimestamp(2, java.sql.Timestamp.valueOf(java.time.LocalDateTime.now()));
  

For people who have found this post from Google almost 6 years in the future (and beyond!), you may run into this problem with Apache 2 and PHP 7 while also using the UserDir module.

Another possible cause of this problem could be that you are trying to run the script in a "user directory" from the the UserDir module. Running PHP scripts in user directories is disabled by default. You will run into this problem if the script is in the public_html directory in your home folder and you are trying to access it from http://localhost/~your_username.

To fix this, open up /etc/apache2/mods-enabled/php7.2.conf. You must comment or delete the tag block at the bottom that reads

<IfModule mod_userdir.c>
    <Directory /home/*/public_html>
        php_admin_flag engine Off
    </Directory>
</IfModule>

I had a similar problem. But the problem was in the file name '.htaccess', because the Windows doesn't let the file's name begin with a ".", the solution was rename the file with a CMD command. "rename c:\xampp\htdocs\htaccess.txt .htaccess"

All the modern browsers provides you storage apis. You can use them (localStorage or sessionStorage) to save your data.

All you have to do is after receiving the response store it to browser storage. Then next time you find the same call, search if the response is saved already. If yes, return the response from there; if not make a fresh call.

Smartjax plugin also does similar things; but as your requirement is just saving the call response, you can write your code inside your jQuery ajax success function to save the response. And before making call just check if the response is already saved.

You should not replace the text entirely. Add the text after the "# END WordPress".

i solved this by http://willcodeforcoffee.com/2007/01/31/cakephp-error-500-too-many-redirects/ just uncomment or add this:

RewriteBase /
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]

to your .htaccess file

This works.

 $("div.row-form input[type='checkbox']").attr('checked','checked');

disabling PHP-FPM fixed my issue.

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

Notes: Make sure you have done the following steps

1. sudo a2enmod rewrite
2. sudo service apache2 restart
3. Add Following in your vhost file, located at /etc/apache2/sites-available/000-default.conf

<Directory /var/www/html>
  Options Indexes FollowSymLinks MultiViews
  AllowOverride All
  Order allow,deny
  allow from all
  Require all granted
</Directory>

Now your .htaccess will work and your site will redirect to http:// to https://www

Try this in the .htaccess of the external root folder :

<IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
</IfModule>

And if it only concerns .js scripts you should wrap the above code inside this:

<FilesMatch "\.(js)$">
...
</FilesMatch>

I am working on MacOS, following operation solved my problem:

I copied from : https://akrabat.com/setting-up-php-mysql-on-os-x-10-7-lion/

cd /etc/apache2

Give write permission the config file to root: sudo chmod u+w httpd.conf sudo vim httpd.conf

Find #LoadModule php5_module libexec/apache2/libphp5.so

and remove the leading #

Find #LoadModule rewrite_module libexec/apache2/mod_rewrite.so

and remove the leading #

Find AllowOverride None within the section and change to AllowOverride All so that .htaccess files will work.

Change permissions back: sudo chmod u-w httpd.conf

Restart Apache by running following in terminal:

sudo apachectl restart

Enable compression via .htaccess

For most people reading this, compression is enabled by adding some code to a file called .htaccess on their web host/server. This means going to the file manager (or wherever you go to add or upload files) on your webhost.

The .htaccess file controls many important things for your site.

The code below should be added to your .htaccess file...

<ifModule mod_gzip.c>
mod_gzip_on Yes
mod_gzip_dechunk Yes
mod_gzip_item_include file .(html?|txt|css|js|php|pl)$
mod_gzip_item_include handler ^cgi-script$
mod_gzip_item_include mime ^text/.*
mod_gzip_item_include mime ^application/x-javascript.*
mod_gzip_item_exclude mime ^image/.*
mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
</ifModule>

Save the .htaccess file and then refresh your webpage.

Check to see if your compression is working using the Gzip compression tool.

Your question is mixing a few different concepts. You started out saying you wanted to run sites on the same server using the same domain, but in different folders. That doesn't require any special setup. Once you get the single domain running, you just create folders under that docroot.

Based on the rest of your question, what you really want to do is run various sites on the same server with their own domain names.

The best documentation you'll find on the topic is the virtual host documentation in the apache manual.

There are two types of virtual hosts: name-based and IP-based. Name-based allows you to use a single IP address, while IP-based requires a different IP for each site. Based on your description above, you want to use name-based virtual hosts.

The initial error you were getting was due to the fact that you were using different ports than the NameVirtualHost line. If you really want to have sites served from ports other than 80, you'll need to have a NameVirtualHost entry for each port.

Assuming you're starting from scratch, this is much simpler than it may seem.

If you are using 2.3 or earlier, the first thing you need to do is tell Apache that you're going to use name-based virtual hosts.

NameVirtualHost *:80

If you are using 2.4 or later do not add a NameVirtualHost line. Version 2.4 of Apache deprecated the NameVirtualHost directive, and it will be removed in a future version.

Now your vhost definitions:

<VirtualHost *:80>
    DocumentRoot "/home/user/site1/"
    ServerName site1
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "/home/user/site2/"
    ServerName site2
</VirtualHost>

You can run as many sites as you want on the same port. The ServerName being different is enough to tell Apache which vhost to use. Also, the ServerName directive is always the domain/hostname and should never include a path.

If you decide to run sites on a port other than 80, you'll always have to include the port number in the URL when accessing the site. So instead of going to http://example.com you would have to go to http://example.com:81

In your .htaccess you can add:

PHP 5.x

<IfModule mod_php5.c>
    php_value memory_limit 64M
</IfModule>

PHP 7.x

<IfModule mod_php7.c>
    php_value memory_limit 64M
</IfModule>

If page breaks again, then you are using PHP as mod_php in apache, but error is due to something else.

If page does not break, then you are using PHP as CGI module and therefore cannot use php values - in the link I've provided might be solution but I'm not sure you will be able to apply it.

    I changed 
    Order Deny,Allow
    Deny From All      in .htaccess to   " Require all denied "    and restarted apache but it did not help.

Path for apache2.conf in ubuntu is /etc/apache2/apache.conf

Then I added following lines in apache2.conf and then my folder is working fine

    <Directory /path of required folder>
            Options Indexes FollowSymLinks
            AllowOverride All
            Require all granted
       </Directory>

   and run  " Sudo service apache2 restart " 

There can be many causes to this problem.

My suggestion is to turn on WP_DEBUG in wp-config.php

define('WP_DEBUG', true);

I am using xampp 1.7.3. Using inspiration from here: xampp 1.7.3 upgrade broken virtual hosts access forbidden

INSTEAD OF add <Directory> .. </Directory> in httpd-vhosts.conf, I add it in httpd.conf right after <Directory "D:/xampplite/cgi-bin"> .. </Directory>.

Here is what I add in httpd.conf:

<Directory "D:/CofeeShop">
    AllowOverride All
    Options  All
    Order allow,deny
    Allow from all
</Directory>

And here is what I add in httpd-vhosts.conf

<VirtualHost *:8001>
    ServerAdmin [email protected]
    DocumentRoot "D:/CofeeShop"
    ServerName localhost:8001
</VirtualHost>

I also add Listen 8001 in httpd.conf to complete my setting.

Hope it helps

1) Are you sure mod_rewrite module is enabled? Check phpinfo()

2) Your above rule assumes the URL starts with "folder". Is this correct? Did you acutally want to have folder in the URL? This would match a URL like:

/folder/thing -> /folder/thing.php

If you actually want

/thing -> /folder/thing.php

You need to drop the folder from the match expression.

I usually use this to route request to page without php (but yours should work which leads me to think that mod_rewrite may not be enabled):

RewriteRule ^([^/\.]+)/?$ $1.php  [L,QSA]

3) Assuming you are declaring your rules in an .htaccess file, does your installation allow for setting Options (AllowOverride) overrides in .htaccess files? Some shared hosts do not.

When the server finds an .htaccess file (as specified by AccessFileName) it needs to know which directives declared in that file can override earlier access information.

Use the mod rewrite with R=301 - where you use a incremental version number:

To achieve > css/ver/file.css => css/file.css?v=ver

RewriteRule ^css/([0-9]+)/file.css$ css/file.css?v=$1 [R=301,L,QSA]

so example, css/10/file.css => css/file.css?v=10

Same can be applied to js/ files. Increment ver to force update, 301 forces re-cache

I have tested this across Chrome, Firefox, Opera etc

PS: the ?v=ver is just for readability, this does not cause the refresh

If you are in linux system, you can check all enable modules for apache2(in my case) in the following folder:/etc/apache2/mods-available

cd /etc/apache2/mods-available

to type: ll -a
if you want to check the available modules for php (in this case php 7 ) folder /etc/php/7.0/mods-available

cd /etc/php/7.0/mods-available

to type: ll -a

This is what I use to control headers/caching, I'm not an Apache pro, so let me know if there is room for improvement, but I know that this has been working well on all of my sites for some time now.

Mod_expires

http://httpd.apache.org/docs/2.2/mod/mod_expires.html

This module controls the setting of the Expires HTTP header and the max-age directive of the Cache-Control HTTP header in server responses. The expiration date can set to be relative to either the time the source file was last modified, or to the time of the client access.

These HTTP headers are an instruction to the client about the document's validity and persistence. If cached, the document may be fetched from the cache rather than from the source until this time has passed. After that, the cache copy is considered "expired" and invalid, and a new copy must be obtained from the source.

# BEGIN Expires
<ifModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access plus 1 seconds"
ExpiresByType text/html "access plus 1 seconds"
ExpiresByType image/gif "access plus 2592000 seconds"
ExpiresByType image/jpeg "access plus 2592000 seconds"
ExpiresByType image/png "access plus 2592000 seconds"
ExpiresByType text/css "access plus 604800 seconds"
ExpiresByType text/javascript "access plus 216000 seconds"
ExpiresByType application/x-javascript "access plus 216000 seconds"
</ifModule>
# END Expires

Mod_headers

http://httpd.apache.org/docs/2.2/mod/mod_headers.html

This module provides directives to control and modify HTTP request and response headers. Headers can be merged, replaced or removed.

# BEGIN Caching
<ifModule mod_headers.c>
<filesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|swf)$">
Header set Cache-Control "max-age=2592000, public"
</filesMatch>

</filesMatch>
<filesMatch "\.(html|htm|php)$">

</filesMatch>
</ifModule>
# END Caching

I know this question already has an accepted answer, but the Apache documentation says:

The Allow, Deny, and Order directives, provided by mod_access_compat, are deprecated and will go away in a future version. You should avoid using them, and avoid outdated tutorials recommending their use.

So, a more future-proof answer would be:

<RequireAll>
    Require ip xx.xx.xx.xx yy.yy.yy.yy
</RequireAll>

Hopefully, I've helped prevent this page from becoming one of those "outdated tutorials". :)

click: WAMP icon->Apache->Apache modules->chose rewrite_module

and do restart for all services.

Here is a C function that handles positive OR negative integer OR fractional values for BOTH OPERANDS

#include <math.h>
float mod(float a, float N) {return a - N*floor(a/N);} //return in range [0, N)

This is surely the most elegant solution from a mathematical standpoint. However, I'm not sure if it is robust in handling integers. Sometimes floating point errors creep in when converting int -> fp -> int.

I am using this code for non-int s, and a separate function for int.

NOTE: need to trap N = 0!

Tester code:

#include <math.h>
#include <stdio.h>

float mod(float a, float N)
{
    float ret = a - N * floor (a / N);

    printf("%f.1 mod %f.1 = %f.1 \n", a, N, ret);

    return ret;
}

int main (char* argc, char** argv)
{
    printf ("fmodf(-10.2, 2.0) = %f.1  == FAIL! \n\n", fmodf(-10.2, 2.0));

    float x;
    x = mod(10.2f, 2.0f);
    x = mod(10.2f, -2.0f);
    x = mod(-10.2f, 2.0f);
    x = mod(-10.2f, -2.0f);

    return 0;
}

(Note: You can compile and run it straight out of CodePad: http://codepad.org/UOgEqAMA)

Output:

fmodf(-10.2, 2.0) = -0.20 == FAIL!

10.2 mod 2.0 = 0.2
10.2 mod -2.0 = -1.8
-10.2 mod 2.0 = 1.8
-10.2 mod -2.0 = -0.2

Good suggestion, however, nt so accurate in all cases. I figure one out. Please you need to make sure you run "enable-migrations" using PM windows in Visual Studio, and Migration folder would be added to you project.

Make sure the two c# class files added to the folder on will contain all your models and their respective properties.

If you have all that build the solution, and publis for deployment.

The logic is that the existing metadata cannot be overwritten because your application has no metadata to replace the current. As a result you are getting this error "The model backing the context has changed since the database was created"

Here's a detailed explanation about the calculation of MaxClients and MaxRequestsPerChild

http://web.archive.org/web/20160415001028/http://www.genericarticles.com/mediawiki/index.php?title=How_to_optimize_apache_web_server_for_maximum_concurrent_connections_or_increase_max_clients_in_apache

ServerLimit 16
StartServers 2
MaxClients 200
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25

First of all, whenever an apache is started, it will start 2 child processes which is determined by StartServers parameter. Then each process will start 25 threads determined by ThreadsPerChild parameter so this means 2 process can service only 50 concurrent connections/clients i.e. 25x2=50. Now if more concurrent users comes, then another child process will start, that can service another 25 users. But how many child processes can be started is controlled by ServerLimit parameter, this means that in the configuration above, I can have 16 child processes in total, with each child process can handle 25 thread, in total handling 16x25=400 concurrent users. But if number defined in MaxClients is less which is 200 here, then this means that after 8 child processes, no extra process will start since we have defined an upper cap of MaxClients. This also means that if I set MaxClients to 1000, after 16 child processes and 400 connections, no extra process will start and we cannot service more than 400 concurrent clients even if we have increase the MaxClient parameter. In this case, we need to also increase ServerLimit to 1000/25 i.e. MaxClients/ThreadsPerChild=40 So this is the optmized configuration to server 1000 clients

<IfModule mpm_worker_module>
    ServerLimit          40
    StartServers          2
    MaxClients          1000
    MinSpareThreads      25
    MaxSpareThreads      75 
    ThreadsPerChild      25
    MaxRequestsPerChild   0
</IfModule>

I thought the regular modulus operator would work for this in java, but it can't be hard to code. Just divide the numerator by the denominator, and take the integer portion of the result. Multiply that by the denominator, and subtract the result from the numerator.

x = n / d
xint = Integer portion of x
result = n - d * xint

Try to disable ModSecurity from your cPanel. Log into your cPanel. Find the category "Security". There you can find ModSecurity link.Click on it and disable it for the domain you are facing the 403 error.

Some 403 errors can be solved by this method too. Go to the wordpress dashboard, settings>permalink and just click save.

Hope this helped. :)

This is intended behavior.

When you make an HTTP request, the server normally returns code 200 OK. If you set If-Modified-Since, the server may return 304 Not modified (and the response will not have the content). This is supposed to be your cue that the page has not been modified.

The authors of the class have foolishly decided that 304 should be treated as an error and throw an exception. Now you have to clean up after them by catching the exception every time you try to use If-Modified-Since.

Using Blah.valueOf(string) is best but you can use Enum.valueOf(Blah.class, string) as well.

The Sass way of changing bootstrap variables is actually documented on the bootstrap-sass github page.

Just redefine the variables before you @import bootstrap:

$grid-float-breakpoint: 1000px;

@import 'bootstrap';

I think I have found more elegant and less error prone solution using

ScrollView.requestChildRectangleOnScreen

There is no math involved, and contrary to other proposed solutions, it will handle correctly scrolling both up and down.

/**
 * Will scroll the {@code scrollView} to make {@code viewToScroll} visible
 * 
 * @param scrollView parent of {@code scrollableContent}
 * @param scrollableContent a child of {@code scrollView} whitch holds the scrollable content (fills the viewport).
 * @param viewToScroll a child of {@code scrollableContent} to whitch will scroll the the {@code scrollView}
 */
void scrollToView(ScrollView scrollView, ViewGroup scrollableContent, View viewToScroll) {
    Rect viewToScrollRect = new Rect(); //coordinates to scroll to
    viewToScroll.getHitRect(viewToScrollRect); //fills viewToScrollRect with coordinates of viewToScroll relative to its parent (LinearLayout) 
    scrollView.requestChildRectangleOnScreen(scrollableContent, viewToScrollRect, false); //ScrollView will make sure, the given viewToScrollRect is visible
}

It is a good idea to wrap it into postDelayed to make it more reliable, in case the ScrollView is being changed at the moment

/**
 * Will scroll the {@code scrollView} to make {@code viewToScroll} visible
 * 
 * @param scrollView parent of {@code scrollableContent}
 * @param scrollableContent a child of {@code scrollView} whitch holds the scrollable content (fills the viewport).
 * @param viewToScroll a child of {@code scrollableContent} to whitch will scroll the the {@code scrollView}
 */
private void scrollToView(final ScrollView scrollView, final ViewGroup scrollableContent, final View viewToScroll) {
    long delay = 100; //delay to let finish with possible modifications to ScrollView
    scrollView.postDelayed(new Runnable() {
        public void run() {
            Rect viewToScrollRect = new Rect(); //coordinates to scroll to
            viewToScroll.getHitRect(viewToScrollRect); //fills viewToScrollRect with coordinates of viewToScroll relative to its parent (LinearLayout) 
            scrollView.requestChildRectangleOnScreen(scrollableContent, viewToScrollRect, false); //ScrollView will make sure, the given viewToScrollRect is visible
        }
    }, delay);
}

You need to use css. It's how modern web design gets things done.

This is a basic css walk through.

Your html file would be like:

(really simple html)

    <html>
    <head>
    <link rel="stylesheet" type="text/css" href="mystyle.css" />
    </head>
    <body>
    </body>
    <html>

Your css file (mystyle.css) would look like:

body 
{
 margin-top:0px;
 margin-left:0px;
 margin-right:0px;

}

chmod +w <directory>

if you are using phonegap / cordova applications, just edit your config.xml and add the android-versionCode and version in the widget.

<widget id="com.xxx.yyy" version="1.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0" android-versionCode="100001" version="1.0.1">

How can I display these open transactions and commit or cancel them?

There is no open transaction, MySQL will rollback the transaction upon disconnect.
You cannot commit the transaction (IFAIK).

You display threads using

SHOW FULL PROCESSLIST  

See: http://dev.mysql.com/doc/refman/5.1/en/thread-information.html

It will not help you, because you cannot commit a transaction from a broken connection.

What happens when a connection breaks
From the MySQL docs: http://dev.mysql.com/doc/refman/5.0/en/mysql-tips.html

4.5.1.6.3. Disabling mysql Auto-Reconnect

If the mysql client loses its connection to the server while sending a statement, it immediately and automatically tries to reconnect once to the server and send the statement again. However, even if mysql succeeds in reconnecting, your first connection has ended and all your previous session objects and settings are lost: temporary tables, the autocommit mode, and user-defined and session variables. Also, any current transaction rolls back.

This behavior may be dangerous for you, as in the following example where the server was shut down and restarted between the first and second statements without you knowing it:

Also see: http://dev.mysql.com/doc/refman/5.0/en/auto-reconnect.html

How to diagnose and fix this
To check for auto-reconnection:

If an automatic reconnection does occur (for example, as a result of calling mysql_ping()), there is no explicit indication of it. To check for reconnection, call mysql_thread_id() to get the original connection identifier before calling mysql_ping(), then call mysql_thread_id() again to see whether the identifier has changed.

Make sure you keep your last query (transaction) in the client so that you can resubmit it if need be.
And disable auto-reconnect mode, because that is dangerous, implement your own reconnect instead, so that you know when a drop occurs and you can resubmit that query.

Just add float left property on all the divs you want to make appear in a row other than last one. here is example

<div>
  <div style="float: left;">A</div>
  <div style="float: left;">B</div>
  <div>C</div>
</div>

With recent git versions you can git add -N the file (or --intent-to-add), which adds a zero-length blob to the index at that location. The upshot is that your "untracked" file now becomes a modification to add all the content to this zero-length file, and that shows up in the "git diff" output.

git diff

echo "this is a new file" > new.txt
git diff

git add -N new.txt
git diff
diff --git a/new.txt b/new.txt
index e69de29..3b2aed8 100644
--- a/new.txt
+++ b/new.txt
@@ -0,0 +1 @@
+this is a new file

Sadly, as pointed out, you can't git stash while you have an --intent-to-add file pending like this. Although if you need to stash, you just add the new files and then stash them. Or you can use the emulation workaround:

git update-index --add --cacheinfo \
100644 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 new.txt

(setting up an alias is your friend here).

You can just return ItemViewType and use it. See below code:

@Override
public int getItemViewType(int position) {

    Message item = messageList.get(position);
    // return my message layout
    if(item.getUsername() == Message.userEnum.I)
        return R.layout.item_message_me;
    else
        return R.layout.item_message; // return other message layout
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
    View view = LayoutInflater.from(viewGroup.getContext()).inflate(viewType, viewGroup, false);
    return new ViewHolder(view);
}

This is an old question, but I am still able to see this at the top of the search result of Google, so I guess it would be meaningful to add a new answer 4 years after the question is asked.

First of all, there is better support in storing JSON in RDBMS. You may consider switching to PostgreSQL (although MySQL has supported JSON since v5.7.7). PostgreSQL uses very similar SQL commands as MySQL except they support more functions. One of the functions they added is that they provide JSON data type and you are now able to query the JSON stored. (Some reference on this) If you are not making up the query directly in your program, for example, using PDO in php or eloquent in Laravel, all you need to do is just to install PostgreSQL on your server and change database connection settings. You don't even need to change your code.

Most of the time, as the other answers suggested, storing data as JSON directly in RDBMS is not a good idea. There are some exception though. One situation I can think of is a field with variable number of linked entry.

For example, for storing tag of a blog post, normally you will need to have a table for blog post, a table of tag and a matching table. So, when the user wants to edit a post and you need to display which tag is related to that post, you will need to query 3 tables. This will damage the performance a lot if your matching table / tag table is long.

By storing the tags as JSON in the blog post table, the same action only requires a single table search. The user will then be able to see the blog post to be edit quicker, but this will damage the performance if you want to make a report on what post is linked to a tag, or maybe search by tag.

You may also try to de-normalize the database. By duplicating the data and storing the data in both ways, you can receive benefit of both method. You will just need a little bit more time to store your data and more storage space (which is cheap comparing to the cost of more computing power)

using select-object for example:

Get-ADUser -Filter * -SearchBase 'OU=Users & Computers, DC=aaaaaaa, DC=com' -Properties DisplayName | select -expand displayname | Export-CSV "ADUsers.csv" 

So I got this to work today. My URL is http://localhost:8888. The domain I gave facebook is localhost. I thought that it was not working because I was trying to pull data using the FB.api method. I kept on getting an "undefined" name and an image without a source, so definitely didn't have access to the Graph.

Later I realized that my problem was really that I was only passing a first argument of /me to FB.api, and I didn't have a token. So you'll need to use the FB.getLoginStatus function to get a token, which should be added to the /me argument.

You actually don't need any jQuery to check if there is an overflow happening or not. Using element.offsetHeight, element.offsetWidth , element.scrollHeight and element.scrollWidth you can determine if your element have content bigger than it's size:

if (element.offsetHeight < element.scrollHeight ||
    element.offsetWidth < element.scrollWidth) {
    // your element have overflow
} else {
    // your element doesn't have overflow
}

See example in action: Fiddle

But if you want to know what element inside your element is visible or not then you need to do more calculation. There is three states for a child element in terms of visibility:

If you want to count semi-visible items it would be the script you need:

var invisibleItems = [];
for(var i=0; i<element.childElementCount; i++){
  if (element.children[i].offsetTop + element.children[i].offsetHeight >
      element.offsetTop + element.offsetHeight ||
      element.children[i].offsetLeft + element.children[i].offsetWidth >
      element.offsetLeft + element.offsetWidth ){

        invisibleItems.push(element.children[i]);
    }

}

And if you don't want to count semi-visible you can calculate with a little difference.

I believe what you are looking for is assign_attributes.

It's basically the same as update_attributes but it doesn't save the record:

class User < ActiveRecord::Base
  attr_accessible :name
  attr_accessible :name, :is_admin, :as => :admin
end

user = User.new
user.assign_attributes({ :name => 'Josh', :is_admin => true }) # Raises an ActiveModel::MassAssignmentSecurity::Error
user.assign_attributes({ :name => 'Bob'})
user.name        # => "Bob"
user.is_admin?   # => false
user.new_record? # => true

Old question and all of that. But this is yet another way that offers some advantages.

On Windows, you could ask the task scheduler to start your app again for you. This has the advantage of waiting a specific amount of time before the app is restarted. You can go to task manager and delete the task and it stops repeating.

SimpleDateFormat hhmm = new SimpleDateFormat("kk:mm");    
Calendar aCal = Calendar.getInstance(); 
aCal.add(Calendar.SECOND, 65);
String nextMinute = hhmm.format(aCal.getTime()); //Task Scheduler Doesn't accept seconds and won't do current minute.
String[] create = {"c:\\windows\\system32\\schtasks.exe", "/CREATE", "/F", "/TN", "RestartMyProg", "/SC", "ONCE", "/ST", nextMinute, "/TR", "java -jar c:\\my\\dev\\RestartTest.jar"};  
Process proc = Runtime.getRuntime().exec(create, null, null);
System.out.println("Exit Now");
try {Thread.sleep(1000);} catch (Exception e){} // just so you can see it better
System.exit(0);

Using a ScaleGestureDetector

When learning a new concept I don't like using libraries or code dumps. I found a good description here and in the documentation of how to resize an image by pinching. This answer is a slightly modified summary. You will probably want to add more functionality later, but it will help you get started.

Layout

The ImageView just uses the app logo since it is already available. You can replace it with any image you like, though.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@mipmap/ic_launcher"
        android:layout_centerInParent="true"/>

</RelativeLayout>

Activity

We use a ScaleGestureDetector on the activity to listen to touch events. When a scale (ie, pinch) gesture is detected, then the scale factor is used to resize the ImageView.

public class MainActivity extends AppCompatActivity {

    private ScaleGestureDetector mScaleGestureDetector;
    private float mScaleFactor = 1.0f;
    private ImageView mImageView;

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

        // initialize the view and the gesture detector
        mImageView = findViewById(R.id.imageView);
        mScaleGestureDetector = new ScaleGestureDetector(this, new ScaleListener());
    }

    // this redirects all touch events in the activity to the gesture detector
    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return mScaleGestureDetector.onTouchEvent(event);
    }

    private class ScaleListener extends ScaleGestureDetector.SimpleOnScaleGestureListener {

        // when a scale gesture is detected, use it to resize the image
        @Override
        public boolean onScale(ScaleGestureDetector scaleGestureDetector){
            mScaleFactor *= scaleGestureDetector.getScaleFactor();
            mImageView.setScaleX(mScaleFactor);
            mImageView.setScaleY(mScaleFactor);
            return true;
        }
    }
}

Notes

• Although the activity had the gesture detector in the example above, it could have also been set on the image view itself.

• You can limit the size of the scaling with something like

  mScaleFactor = Math.max(0.1f, Math.min(mScaleFactor, 5.0f));
  

• Thanks again to Pinch-to-zoom with multi-touch gestures In Android

• Documentation
• Use Ctrl + mouse drag to simulate a pinch gesture in the emulator.

Going on

You will probably want to do other things like panning and scaling to some focus point. You can develop these things yourself, but if you would like to use a pre-made custom view, copy TouchImageView.java into your project and use it like a normal ImageView. It worked well for me and I only ran into one bug. I plan to further edit the code to remove the warning and the parts that I don't need. You can do the same.

From the node.js documentation, "To have a module execute code multiple times, export a function, and call that function", you could use node.js module.export and have a single file to manage the db connections.You can find more at Node.js documentation. Let's say db.js file be like:

    const mysql = require('mysql');

    var connection;

    module.exports = {

    dbConnection: function () {

        connection = mysql.createConnection({
            host: "127.0.0.1",
            user: "Your_user",
            password: "Your_password",
            database: 'Your_bd'
        });
        connection.connect();
        return connection;
    }

    };

Then, the file where you are going to use the connection could be like useDb.js:

const dbConnection = require('./db');

var connection;

function callDb() {

    try {

        connection = dbConnectionManager.dbConnection();

        connection.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
            if (!error) {

                let response = "The solution is: " + results[0].solution;
                console.log(response);

            } else {
                console.log(error);
            }
        });
        connection.end();


    } catch (err) {
        console.log(err);
    }
}

Yes, you can.

From cplusplus.com:

Because these functions are operator overloading functions, the usual way in which they are called is:

   strm >> variable;

Where strm is the identifier of a istream object and variable is an object of any type supported as right parameter. It is also possible to call a succession of extraction operations as:

   strm >> variable1 >> variable2 >> variable3; //...

which is the same as performing successive extractions from the same object strm.

Just replace strm with cin.

I am using Laravel 8 and just installed the fruitcake/laravel-cors and use it in app/Http/Kernel.php like blow:

protected $middleware = [
      ....
         \Fruitcake\Cors\HandleCors::class,
    ];

note : add it to end of array like me

LINQ one-line solution:

myArray = myArray.Where((source, index) => index != 1).ToArray();

The 1 in that example is the index of the element to remove -- in this example, per the original question, the 2nd element (with 1 being the second element in C# zero-based array indexing).

A more complete example:

string[] myArray = { "a", "b", "c", "d", "e" };
int indexToRemove = 1;
myArray = myArray.Where((source, index) => index != indexToRemove).ToArray();

After running that snippet, the value of myArray will be { "a", "c", "d", "e" }.

Create a new file:

MyListener.java:

public interface MyListener {
    // you can define any parameter as per your requirement
    public void callback(View view, String result);
}

In your activity, implement the interface:

MyActivity.java:

public class MyActivity extends Activity implements MyListener {
   @override        
   public void onCreate(){
        MyButton m = new MyButton(this);
   }

    // method is invoked when MyButton is clicked
    @override
    public void callback(View view, String result) {   
        // do your stuff here
    }
}

In your custom class, invoke the interface when needed:

MyButton.java:

public class MyButton {
    MyListener ml;

    // constructor
    MyButton(MyListener ml) {
        //Setting the listener
        this.ml = ml;
    }

    public void MyLogicToIntimateOthers() {
        //Invoke the interface
        ml.callback(this, "success");
    }
}

Can be done with toLocaleDateString

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleDateString

<script>_x000D_
const date = new Date();_x000D_
const formattedDate = date.toLocaleDateString('en-GB', {_x000D_
  day: '2-digit', month: 'short', year: 'numeric'_x000D_
}).replace(/ /g, '-');_x000D_
document.write(formattedDate);_x000D_
</script>

Change the platform toolset to: "Windows7.1SDK" under project properties->configuration properties->general

Take a look at the library I wrote: https://github.com/tachyons-css/react-native-style-tachyons

It allows you to specify a root-fontSize (rem) upon start, which you can make dependent of your PixelRatio or other device-characteristics.

Then you get styles relative to your rem, not only fontSize, but paddings etc. as well:

<Text style={[s.f5, s.pa2, s.tc]}>
     Something
</Text>

Expanation:

• f5is always your base-fontsize
• pa2 gives you padding relative to your base-fontsize.

Just call componentsSeparatedByString method on your fullName

import Foundation

var fullName: String = "First Last"
let fullNameArr = fullName.componentsSeparatedByString(" ")

var firstName: String = fullNameArr[0]
var lastName: String = fullNameArr[1]

Update for Swift 3+

import Foundation

let fullName    = "First Last"
let fullNameArr = fullName.components(separatedBy: " ")

let name    = fullNameArr[0]
let surname = fullNameArr[1]

You can:

mkdir -p folder/subfolder

The -p flag causes any parent directories to be created if necessary.

Here is another one, I think. Just for reference. Let's set a variable to be an instantance of class StringVar

If you program Tk using the Tcl language, you can ask the system to let you know when a variable is changed. The Tk toolkit can use this feature, called tracing, to update certain widgets when an associated variable is modified.

There’s no way to track changes to Python variables, but Tkinter allows you to create variable wrappers that can be used wherever Tk can use a traced Tcl variable.

text = StringVar()
self.depositLabel = Label(self.__mainWindow, text = self.labelText, textvariable = text)
                                                                    ^^^^^^^^^^^^^^^^^
  def depositCallBack(self,event):
      text.set('change the value')

I had this challenge when working on a Rails 6 API application in Ubuntu 20.04.

I had already existing models, and I needed to generate corresponding controllers for the models and also add their allowed attributes in the controller params.

Here's how I did it:

I used the rails generate scaffold_controller to get it done.

I simply ran the following commands:

rails generate scaffold_controller School name:string logo:json motto:text address:text

rails generate scaffold_controller Program name:string logo:json school:references

This generated the corresponding controllers for the models and also added their allowed attributes in the controller params, including the foreign key attributes.

create  app/controllers/schools_controller.rb
invoke  test_unit
create    test/controllers/schools_controller_test.rb

create  app/controllers/programs_controller.rb
invoke  test_unit
create    test/controllers/programs_controller_test.rb

That's all.

I hope this helps

All the other solutions suggested here, as well as most other JavaScript libraries that do HTML entity encoding/decoding, make several mistakes:

• They don’t implement the full list of named character references that browsers support. For example, htmlDecode('≼') should return '?' (i.e. '\u227C').
• They don’t support encoding astral symbols correctly. For example, htmlEncode('') should return something like 𝌆 or 𝌆. If an implementation returns two separate entities instead (e.g. �� or ��), it is broken.
• They don’t support decoding astral symbols correctly. htmlDecode('𝌆') should return '' and not '?' (i.e. '\uD306').
• They don’t implement the character reference overrides table listed in the HTML Standard. For example, htmlDecode('€') should return '€' (i.e. '\u20AC').
• They should perform decoding in a single pass. For example, htmlDecode('&') should return '&', not &.

For a robust solution that avoids all these issues, use a library I wrote called he for this. From its README:

he (for “HTML entities”) is a robust HTML entity encoder/decoder written in JavaScript. It supports all standardized named character references as per HTML, handles ambiguous ampersands and other edge cases just like a browser would, has an extensive test suite, and — contrary to many other JavaScript solutions — he handles astral Unicode symbols just fine. An online demo is available.

A common pre-C++11 idiom is to pass a reference to the object being filled.

Then there is no copying of the vector.

void f( std::vector & result )
{
  /*
    Insert elements into result
  */
} 

Another way could be through adding .LNK to your $PATHEX. Then just create a shortcut to your executable (ie: yourshortcut.lnk) and put it into any of the directories listed within $PATH.

WARNING NOTE: Know that any .lnk files located in any directories listed in your $PATH are now "PATH'ed" as well. For this reason, I would favor the batch file method mentionned earlier to this method.

Yes It is possible.

You have to create a custom view which extends text view.

In attrs.xml in values folder:

<resources>
    <declare-styleable name="MyTextView">
        <attr name="first_name" format="string"/>
        <attr name="last_name" format="string"/>
        <attr name="ttf_name" format="string"/>
    </declare-styleable>
</resources>

In main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:lht="http://schemas.android.com/apk/res/com.lht"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <TextView  android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
        android:text="Hello"/>
    <com.lht.ui.MyTextView  
        android:id="@+id/MyTextView"
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
        android:text="Hello friends"
        lht:ttf_name="ITCBLKAD.TTF"
        />   
</LinearLayout>

In MyTextView.java:

package com.lht.ui;

import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.util.Log;
import android.widget.TextView;

public class MyTextView extends TextView {

    Context context;
    String ttfName;

    String TAG = getClass().getName();

    public MyTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.context = context;

        for (int i = 0; i < attrs.getAttributeCount(); i++) {
            Log.i(TAG, attrs.getAttributeName(i));
            /*
             * Read value of custom attributes
             */

            this.ttfName = attrs.getAttributeValue(
                    "http://schemas.android.com/apk/res/com.lht", "ttf_name");
            Log.i(TAG, "firstText " + firstText);
            // Log.i(TAG, "lastText "+ lastText);

            init();
        }

    }

    private void init() {
        Typeface font = Typeface.createFromAsset(context.getAssets(), ttfName);
        setTypeface(font);
    }

    @Override
    public void setTypeface(Typeface tf) {

        // TODO Auto-generated method stub
        super.setTypeface(tf);
    }

}

You can use /start /max [your batch] it will fill the screen with the program it oppose to /min

It doesn't matter. In terms of REST, you can't do a GET, because it's not cacheable, but it doesn't matter if you use POST or PATCH or PUT or whatever, and it doesn't matter what the URL looks like. If you're doing REST, what matters is that when you get a representation of your resource from the server, that representation is able give the client state transition options.

If your GET response had state transitions, the client just needs to know how to read them, and the server can change them if needed. Here an update is done using POST, but if it was changed to PATCH, or if the URL changes, the client still knows how to make an update:

{
  "customer" :
  {
  },
  "operations":
  [
    "update" : 
    {
      "method": "POST",
      "href": "https://server/customer/123/"
    }]
}

You could go as far as to list required/optional parameters for the client to give back to you. It depends on the application.

As far as business operations, that might be a different resource linked to from the customer resource. If you want to send an email to the customer, maybe that service is it's own resource that you can POST to, so you might include the following operation in the customer resource:

"email":
{
  "method": "POST",
  "href": "http://server/emailservice/send?customer=1234"
}

Some good videos, and example of the presenter's REST architecture are these. Stormpath only uses GET/POST/DELETE, which is fine since REST has nothing to do with what operations you use or how URLs should look (except GETs should be cacheable):

https://www.youtube.com/watch?v=pspy1H6A3FM,
https://www.youtube.com/watch?v=5WXYw4J4QOU,
http://docs.stormpath.com/rest/quickstart/

Suppose you want to insert a particular line of text (not an empty line):

@echo off
FOR /F %%C IN ('FIND /C /V "" ^<%origfile%') DO SET totallines=%%C
set /a totallines+=1

@echo off
<%origfile% (FOR /L %%i IN (1,1,%totallines%) DO (
  SETLOCAL EnableDelayedExpansion
  SET /p L=
  IF %%i==%insertat% ECHO(!TL!
  ECHO(!L!
  ENDLOCAL
)
) >%tempfile%

COPY /Y %tempfile% %origfile% >NUL

DEL %tempfile%

A complete example for scripted pipepline:

       stage('Build'){
            withEnv(["GOPATH=/ws","PATH=/ws/bin:${env.PATH}"]) {
                sh 'bash build.sh'
            }
        }

The input type=email page of the www.w3.org site notes that an email address is any string which matches the following regular expression:

/^[a-zA-Z0-9.!#$%&’*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/

Use the required attribute and a pattern attribute to require the value to match the regex pattern.

<input
    type="text"
    pattern="/^[a-zA-Z0-9.!#$%&’*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/"
    required
>

That's the function I wrote to get string in Unicode characters:

function nbUnicodeLength(string){
    var stringIndex = 0;
    var unicodeIndex = 0;
    var length = string.length;
    var second;
    var first;
    while (stringIndex < length) {

        first = string.charCodeAt(stringIndex);  // returns an integer between 0 and 65535 representing the UTF-16 code unit at the given index.
        if (first >= 0xD800 && first <= 0xDBFF && string.length > stringIndex + 1) {
            second = string.charCodeAt(stringIndex + 1);
            if (second >= 0xDC00 && second <= 0xDFFF) {
                stringIndex += 2;
            } else {
                stringIndex += 1;
            }
        } else {
            stringIndex += 1;
        }

        unicodeIndex += 1;
    }
    return unicodeIndex;
}

I got a similar error, and it's caused by incorrect proxy setting. This command saved me:

git config --global --unset http.proxy

https version:

git config --global --unset https.proxy

You should be able to do something like this:

I was able to get this to work by using the Invoke-Expression cmdlet.

Invoke-Expression "& `"$scriptPath`" test -r $number -b $testNumber -f $FileVersion -a $ApplicationID"

I tend to version my framework then apply the version number to script and style paths

<cfset fw.version = '001' />
<script src="/scripts/#fw.version#/foo.js"/>

Here is a CSV action result I wrote that takes a DataTable and converts it into CSV. You can return this from your view and it will prompt the user to download the file. You should be able to convert this easily into a List compatible form or even just put your list into a DataTable.

QPython

I use the QPython app. It's free and includes a code editor, an interactive interpreter and a package manager, allowing you to create and execute Python programs directly on your device.

If you're using C with Win32, you can leverage its Structured Exception Handling (SEH) to simulate try/catch.

If you're using C in platforms that don't support setjmp() and longjmp(), have a look at this Exception Handling of pjsip library, it does provide its own implementation

string fileIN = @"C:\myTextFile.txt";
string fileOUT = @"C:\myTextFile_Out.txt";
if (File.Exists(fileIN))
{
    string[] data = File.ReadAllLines(fileIN);
    foreach (string line in data)
        if (!line.Equals("my line to remove"))
            File.AppendAllText(fileOUT, line);
    File.Delete(fileIN);
    File.Move(fileOUT, fileIN);
}

this worked for me:

jQuery('form').attr("placeholder","Wert eingeben");

but now this don't work:

// Prioritize "important" elements on medium.
            skel.on('+medium -medium', function() {
                jQuery.prioritize(
                    '.important\\28 medium\\29',
                    skel.breakpoint('medium').active
                );
            });

You can still view the source on the website by going to View > Page Source from the toolbar in firefox. Or View > source in IE.

The right-click is disabled via javascript. The source for the javascript is:

http://www.immihelp.com/common/utils.js

Keep both lists x and y in sorted order.

If x = y, do your action, if x < y, advance x, if y < x, advance y until either list is empty.

The run time of this intersection is proportional to min (size (x), size (y))

Don't run a .Contains () loop, this is proportional to x * y which is much worse.

You can actually handle all of this with just a simple template tag. See http://jsfiddle.net/m4ve9/ for an example. Note that I actually didn't need a compile or link property on the super-directive definition.

During the compilation process, Angular pulls in the template values before compiling, so you can attach any further directives there and Angular will take care of it for you.

If this is a super directive that needs to preserve the original internal content, you can use transclude : true and replace the inside with <ng-transclude></ng-transclude>

Hope that helps, let me know if anything is unclear

I got it!

$dur = file_get_contents("https://www.googleapis.com/youtube/v3/videos?part=contentDetails&id=$vId&key=dldfsd981asGhkxHxFf6JqyNrTqIeJ9sjMKFcX4");

$duration = json_decode($dur, true);
foreach ($duration['items'] as $vidTime) {
    $vTime= $vidTime['contentDetails']['duration'];
}

There it returns the time for YouTube API version 3 (the key is made up by the way ;). I used $vId that I had gotten off of the returned list of the videos from the channel I am showing the videos from...

It works. Google REALLY needs to include the duration in the snippet so you can get it all with one call instead of two... it's on their 'wontfix' list.

Well I found the answer set "aaSorting" to an empty array:

$(document).ready( function() {
    $('#example').dataTable({
        /* Disable initial sort */
        "aaSorting": []
    });
})

For newer versions of Datatables (>= 1.10) use order option:

$(document).ready( function() {
    $('#example').dataTable({
        /* No ordering applied by DataTables during initialisation */
        "order": []
    });
})

Here's an example of how to create a ColorList programmatically in Kotlin:

val colorList = ColorStateList(
        arrayOf(
                intArrayOf(-android.R.attr.state_enabled),  // Disabled
                intArrayOf(android.R.attr.state_enabled)    // Enabled
        ),
        intArrayOf(
                Color.BLACK,     // The color for the Disabled state
                Color.RED        // The color for the Enabled state
        )
)

The problem is that you are calling GetGridData from a background thread. This method accesses several WPF controls which are bound to the main thread. Any attempt to access them from a background thread will lead to this error.

In order to get back to the correct thread you should use SynchronizationContext.Current.Post. However in this particular case it seems like the majority of the work you are doing is UI based. Hence you would be creating a background thread just to go immediately back to the UI thread and do some work. You need to refactor your code a bit so that it can do the expensive work on the background thread and then post the new data to the UI thread afterwards

And for PHP 5.3, you can use this function, which can be embedded in a class or used in procedural style:

http://svn.kd2.org/svn/misc/libs/tools/json_readable_encode.php

        Dim result2 = From s In mySession.Query(Of CSucursal)()
                      Where (From c In mySession.Query(Of CCiudad)()
                             From cs In mySession.Query(Of CCiudadSucursal)()
                             Where cs.id_ciudad Is c
                             Where cs.id_sucursal Is s
                             Where c.id = IdCiudad
                             Where s.accion <> "E" AndAlso s.accion <> Nothing
                             Where cs.accion <> "E" AndAlso cs.accion <> Nothing
                             Select c.descripcion).Single() Is Nothing
                      Where s.accion <> "E" AndAlso s.accion <> Nothing
                      Select s.id, s.Descripcion

I was researching this a while ago because I wanted to create a custom button that would open the file dialog and start the upload immediately. I just noticed something that might make this possible - firefox seems to open the dialog when you click anywhere on the upload. So the following might do it:

1. Create a file upload and a separate element containing an image that you want to use as the button
2. Arrange them to overlap and make the file element backgroud and border transparent so the button is the only thing visible
3. Add the javascript to make IE open the dialog when the button/file input is clicked
4. Use an onchange event to submit the form when a file is selected

This is only theoretical since I already used another method to solve the problem but it just might work.

Is the problem with SUM(billableDuration)? To find out, try commenting out that line and see if it works.

It could be that the sum is exceeding the maximum int. If so, try replacing it with SUM(CAST(billableDuration AS BIGINT)).

These are the sizes. Try to take a look in Supporting Mutiple Screens

320dp: a typical phone screen (240x320 ldpi, 320x480 mdpi, 480x800 hdpi, etc).
480dp: a tweener tablet like the Streak (480x800 mdpi).
600dp: a 7” tablet (600x1024 mdpi).
720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc).

I use this to make more than one layout:

res/layout/main_activity.xml           # For handsets (smaller than 600dp available width)
res/layout-sw600dp/main_activity.xml   # For 7” tablets (600dp wide and bigger)
res/layout-sw720dp/main_activity.xml   # For 10” tablets (720dp wide and bigger)

You can save it as follow if you have Pandas Dataframe

   df.to_csv(r'/dir/filename.csv')

If you paste the string in server-side into the html don't need to do nothing:

For plain java in jsp:

var jsonObj=<%=jsonStringInJavaServlet%>;

For jsp width struts:

var jsonObj=<s:property value="jsonStringInJavaServlet" escape="false" escapeHtml="false"/>;

Invalid JSON from the server should always be an expected use case. A million things can go wrong during transmission. Gson is a bit tricky, because its error output will give you one problem, and the actual exception you catch will be of a different type.

With all that in mind, the proper fix on the client side is

try
{
  gson.fromJSON(ad, Ad.class);
  //...
}
catch (IllegalStateException | JsonSyntaxException exception)
{
  //...

If you want to know why the JSON you received from the server is wrong, you can look inside your catch block at the exception. But even if it is your problem, it's not the client's responsibility to fix JSON it is receiving from the internet.

Either way, it is the client's responsibility to decide what to do when it gets bad JSON. Two possibilities are rejecting the JSON and doing nothing, and trying again.

If you are going to try again, I highly recommend setting a flag inside the try / catch block and then responding to that flag outside the try / catch block. Nested try / catch is likely how Gson got us into this mess with our stack trace and exceptions not matching up.

In other words, even though I'll admit it doesn't look very elegant, I would recommend

boolean failed = false;

try
{
  gson.fromJSON(ad, Ad.class);
  //...
}
catch (IllegalStateException | JsonSyntaxException exception)
{
  failed = true;
  //...
}

if (failed)
{
  //...

A likely possibility is that your browser reaches your web service through a proxy, and SoapUI is not configured to use that proxy. For example, I work in a corporate environment and while my IE and FireFox can access external websites, my SoapUI can only access internal web services.

The easy solution is to just open the WSDL in a browser, save it to a .xml file, and base your SoapUI project on that. This won't work if your WSDL relies on external XSDs that it can't get to, however.

Confusing messages

These messages are rather misleading and understandably a source of confusion. Older Ubuntu versions used Libav which is a fork of the FFmpeg project. FFmpeg returned in Ubuntu 15.04 "Vivid Vervet".

The fork was basically a non-amicable result of conflicting personalities and development styles within the FFmpeg community. It is worth noting that the maintainer for Debian/Ubuntu switched from FFmpeg to Libav on his own accord due to being involved with the Libav fork.

The real ffmpeg vs the fake one

For a while both Libav and FFmpeg separately developed their own version of ffmpeg.

Libav then renamed their bizarro ffmpeg to avconv to distance themselves from the FFmpeg project. During the transition period the "not developed anymore" message was displayed to tell users to start using avconv instead of their counterfeit version of ffmpeg. This confused users into thinking that FFmpeg (the project) is dead, which is not true. A bad choice of words, but I can't imagine Libav not expecting such a response by general users.

This message was removed upstream when the fake "ffmpeg" was finally removed from the Libav source, but, depending on your version, it can still show up in Ubuntu because the Libav source Ubuntu uses is from the ffmpeg-to-avconv transition period.

In June 2012, the message was re-worded for the package libav - 4:0.8.3-0ubuntu0.12.04.1. Unfortunately the new "deprecated" message has caused additional user confusion.

Starting with Ubuntu 15.04 "Vivid Vervet", FFmpeg's ffmpeg is back in the repositories again.

libav vs Libav

To further complicate matters, Libav chose a name that was historically used by FFmpeg to refer to its libraries (libavcodec, libavformat, etc). For example the libav-user mailing list, for questions and discussions about using the FFmpeg libraries, is unrelated to the Libav project.

How to tell the difference

If you are using avconv then you are using Libav. If you are using ffmpeg you could be using FFmpeg or Libav. Refer to the first line in the console output to tell the difference: the copyright notice will either mention FFmpeg or Libav.

Secondly, the version numbering schemes differ. Each of the FFmpeg or Libav libraries contains a version.h header which shows a version number. FFmpeg will end in three digits, such as 57.67.100, and Libav will end in one digit such as 57.67.0. You can also view the library version numbers by running ffmpeg or avconv and viewing the console output.

If you want to use the real ffmpeg

Ubuntu 15.04 "Vivid Vervet" or newer

The real ffmpeg is in the repository, so you can install it with:

apt-get install ffmpeg

For older Ubuntu versions

Your options are:

• Download a recent Linux build of ffmpeg,
• follow a step-by-step guide to compile ffmpeg,
• or use Doug McMahon's PPA (for Ubuntu 14.04 LTS "Trusty Tahr")

These methods are non-intrusive, reversible, and will not interfere with the system or any repository packages.

Another possible option is to upgrade to Ubuntu 15.04 "Vivid Vervet" or newer and just use ffmpeg from the repository.

Try doing a nav element with a ul element. Mine has a main above but I don't think you need it.

<main>
<nav>
<ul><li><a href="http//www.google.com">search</a>
<li><a href="http//www.google.com">search</a>
<li><a href="http//www.google.com">search</a>

The code is something like this.
When ever I put in the code it wouldn't work right so you need to fill in the blank,
then center it.

main
nav
ul> li> a>: href="link of choice":name of link:/a>

Still nothing good enough using native stuff. Here is what I ended up with:

public static string GetAbsoluteUrl(string url)
{
    //VALIDATE INPUT
    if (String.IsNullOrEmpty(url))
    {
        return String.Empty;
    }

    //VALIDATE INPUT FOR ALREADY ABSOLUTE URL
    if (url.StartsWith("http://", StringComparison.OrdinalIgnoreCase) || url.StartsWith("https://", StringComparison.OrdinalIgnoreCase))
    { 
        return url;
    }

    //GET CONTEXT OF CURRENT USER
    HttpContext context = HttpContext.Current;

    //RESOLVE PATH FOR APPLICATION BEFORE PROCESSING
    if (url.StartsWith("~/"))
    {
        url = (context.Handler as Page).ResolveUrl(url);
    }

    //BUILD AND RETURN ABSOLUTE URL
    string port = (context.Request.Url.Port != 80 && context.Request.Url.Port != 443) ? ":" + context.Request.Url.Port : String.Empty;
    return context.Request.Url.Scheme + Uri.SchemeDelimiter + context.Request.Url.Host + port + "/" + url.TrimStart('/');
}

I might've over-engineered my own solution without realizing that Type.valueOf("enum string") actually existed.

I guess it gives more granular control but I'm not sure it's really necessary.

public enum Type {
    DEBIT,
    CREDIT;

    public static Map<String, Type> typeMapping = Maps.newHashMap();
    static {
        typeMapping.put(DEBIT.name(), DEBIT);
        typeMapping.put(CREDIT.name(), CREDIT);
    }

    public static Type getType(String typeName) {
        if (typeMapping.get(typeName) == null) {
            throw new RuntimeException(String.format("There is no Type mapping with name (%s)"));
        }
        return typeMapping.get(typeName);
    }
}

I guess you're exchanging IllegalArgumentException for RuntimeException (or whatever exception you wish to throw) which could potentially clean up code.

Here is a way to get a NIO FileChannel from System.in and check for availability of data using a timeout, which is a special case of the problem described in the question. Run it at the console, don't type any input, and wait for the results. It was tested successfully under Java 6 on Windows and Linux.

import java.io.FileInputStream;
import java.io.FilterInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.lang.reflect.Field;
import java.nio.ByteBuffer;
import java.nio.channels.ClosedByInterruptException;

public class Main {

    static final ByteBuffer buf = ByteBuffer.allocate(4096);

    public static void main(String[] args) {

        long timeout = 1000 * 5;

        try {
            InputStream in = extract(System.in);
            if (! (in instanceof FileInputStream))
                throw new RuntimeException(
                        "Could not extract a FileInputStream from STDIN.");

            try {
                int ret = maybeAvailable((FileInputStream)in, timeout);
                System.out.println(
                        Integer.toString(ret) + " bytes were read.");

            } finally {
                in.close();
            }

        } catch (Exception e) {
            throw new RuntimeException(e);
        }

    }

    /* unravels all layers of FilterInputStream wrappers to get to the
     * core InputStream
     */
    public static InputStream extract(InputStream in)
            throws NoSuchFieldException, IllegalAccessException {

        Field f = FilterInputStream.class.getDeclaredField("in");
        f.setAccessible(true);

        while( in instanceof FilterInputStream )
            in = (InputStream)f.get((FilterInputStream)in);

        return in;
    }

    /* Returns the number of bytes which could be read from the stream,
     * timing out after the specified number of milliseconds.
     * Returns 0 on timeout (because no bytes could be read)
     * and -1 for end of stream.
     */
    public static int maybeAvailable(final FileInputStream in, long timeout)
            throws IOException, InterruptedException {

        final int[] dataReady = {0};
        final IOException[] maybeException = {null};
        final Thread reader = new Thread() {
            public void run() {                
                try {
                    dataReady[0] = in.getChannel().read(buf);
                } catch (ClosedByInterruptException e) {
                    System.err.println("Reader interrupted.");
                } catch (IOException e) {
                    maybeException[0] = e;
                }
            }
        };

        Thread interruptor = new Thread() {
            public void run() {
                reader.interrupt();
            }
        };

        reader.start();
        for(;;) {

            reader.join(timeout);
            if (!reader.isAlive())
                break;

            interruptor.start();
            interruptor.join(1000);
            reader.join(1000);
            if (!reader.isAlive())
                break;

            System.err.println("We're hung");
            System.exit(1);
        }

        if ( maybeException[0] != null )
            throw maybeException[0];

        return dataReady[0];
    }
}

Interestingly, when running the program inside NetBeans 6.5 rather than at the console, the timeout doesn't work at all, and the call to System.exit() is actually necessary to kill the zombie threads. What happens is that the interruptor thread blocks (!) on the call to reader.interrupt(). Another test program (not shown here) additionally tries to close the channel, but that doesn't work either.

This question has been answered but I feel I should also mention another potential cause. This is a direct result of coming across the same error message but for different reasons. If your list/s are empty the operation will not be performed. check your code for indents and typos

The SSL is not properly configured. Those trustAnchor errors usually mean that the trust store cannot be found. Check your configuration and make sure you are actually pointing to the trust store and that it is in place.

Make sure you have a -Djavax.net.ssl.trustStore system property set and then check that the path actually leads to the trust store.

You can also enable SSL debugging by setting this system property -Djavax.net.debug=all. Within the debug output you will notice it states that it cannot find the trust store.

}

Could be trivial but the _timestamp answer didn't gave an error but not a good result either...

I think it is a nice idea to use traits to store object-to-array converting logic. A simple example:

trait ArrayAwareTrait

    public function toArray()

                if ($item instanceof \DateTime) {
                    return $item->format(DATE_ATOM);
                }
                return $item;
            },

To use Windows SDK successfully you need not only make include files available to your projects but also library files and executables (tools). To set all these directories you should use WinSDK Configuration Tool.

Best solution:

I also had the same problem. I added the following. It works for me

Microsoft.EntityFrameworkCore.SqlServer

You may use this..

<body>
    <form method="" action="">
        <input type="text" name="email" class="input" />
        <input type="submit" value="Sign Up" class="button" />
    </form>
</body>

<script>
    $(document).ready(function() {
        $(".input").val("Email Address");
        $(".input").on("focus", function() {
            $(".input").val("");
        });
        $(".button").on("click", function(event) {
            $(".input").val("");
        });
    });
</script>

Talking of your own code, the problem is that the attr api of jquery is set by

$('.input').attr('value','Email Adress');

and not as you have done:

$('.input').attr('value') = 'Email address';

A lock occurs when multiple processes try to access the same resource at the same time.

One process loses out and must wait for the other to finish.

A deadlock occurs when the waiting process is still holding on to another resource that the first needs before it can finish.

So, an example:

Resource A and resource B are used by process X and process Y

• X starts to use A.
• X and Y try to start using B
• Y 'wins' and gets B first
• now Y needs to use A
• A is locked by X, which is waiting for Y

The best way to avoid deadlocks is to avoid having processes cross over in this way. Reduce the need to lock anything as much as you can.

In databases avoid making lots of changes to different tables in a single transaction, avoid triggers and switch to optimistic/dirty/nolock reads as much as possible.

Some time this error in Joomla appear because some thing incorrect with SESSION or coockie. That may because incorrect HTTPd server setting or because some before CURL or Server http requests

so PHP code like:

  curl_setopt($ch, CURLOPT_URL, $url_page);
  curl_setopt($ch, CURLOPT_HEADER, 1);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
  curl_setopt($ch, CURLOPT_TIMEOUT, 30); 
  curl_setopt($ch, CURLOPT_COOKIESESSION, TRUE);
  curl_setopt($ch, CURLOPT_REFERER, $url_page);
  curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
  curl_setopt($ch, CURLOPT_COOKIEFILE, dirname(__FILE__) . "./cookie.txt");
  curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__) . "./cookie.txt");
  curl_setopt($ch, CURLOPT_COOKIE, session_name() . '=' . session_id());

  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
  if( $sc != "" ) curl_setopt($ch, CURLOPT_COOKIE, $sc);

will need replace to PHP code

  curl_setopt($ch, CURLOPT_URL, $url_page);
  curl_setopt($ch, CURLOPT_HEADER, 1);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
  curl_setopt($ch, CURLOPT_TIMEOUT, 30); 
//curl_setopt($ch, CURLOPT_COOKIESESSION, TRUE);
  curl_setopt($ch, CURLOPT_REFERER, $url_page);
  curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
//curl_setopt($ch, CURLOPT_COOKIEFILE, dirname(__FILE__) . "./cookie.txt");
//curl_setopt($ch, CURLOPT_COOKIEJAR, dirname(__FILE__) . "./cookie.txt");
//curl_setopt($ch, CURLOPT_COOKIE, session_name() . '=' . session_id());

    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false); // !!!!!!!!!!!!!
  //if( $sc != "" ) curl_setopt($ch, CURLOPT_COOKIE, $sc);

May be some body reply how this options connected with "Curl error: Operation timed out after .."

I prefer "<!--" "-->" like a "text>"

<script type="text/javascript">

You get this warning message when the servlet api jar file has already been loaded in the container and you try to load it once again from lib directory.

The Servlet specs say you are not allowed to have servlet.jar in your webapps lib directory.

• Get rid of the warning message by simply removing servlet.jar from your lib directory.
• If you don't find the jar in the lib directory scan for your build path and remove the jar.

C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps\project\WEB-INF\lib

If you are running a maven project, change the javax.servlet-api dependency to scope provided in you pom.xml since the container already provided the servlet jar in itself.

On Mac, change shell to BASH (keep note that virtual env works only in bash shell )

Here's another solution. this one uses very simple syntax. The first example of the accepted solution did not work on older versions of Microsoft SQL (i.e 2000)

SELECT age, count(*)
FROM Students 
GROUP by age
ORDER BY age

Alternate form of the answer by @rumpel

with open(filename, 'w'): pass

This answer fails in a couple of edge cases (see comments). The accepted solution above will handle these. str.splitlines() is the way to go. I will leave this answer nevertheless as reference.

Old (incorrect) answer:

s =  \
"""line1
line2
line3
"""

lines = s.split('\n')
print(lines)
for line in lines:
    print(line)

convert to string and then use built-in functions

unsigned int i;
cout<< to_string(i).length()<<endl;

sum = sum.add(BigInteger.valueOf(i))

The BigInteger class is immutable, hence you can't change its state. So calling "add" creates a new BigInteger, rather than modifying the current.

The max size for a column of type NVARCHAR(MAX) is 2 GByte of storage.

Since NVARCHAR uses 2 bytes per character, that's approx. 1 billion characters.

Leo Tolstoj's War and Peace is a 1'440 page book, containing about 600'000 words - so that might be 6 million characters - well rounded up. So you could stick about 166 copies of the entire War and Peace book into each NVARCHAR(MAX) column.

Is that enough space for your needs? :-)

You need to do something like this:

PrintStream out = new PrintStream(new FileOutputStream("output.txt"));
System.setOut(out);

The second statement is the key. It changes the value of the supposedly "final" System.out attribute to be the supplied PrintStream value.

There are analogous methods (setIn and setErr) for changing the standard input and error streams; refer to the java.lang.System javadocs for details.

A more general version of the above is this:

PrintStream out = new PrintStream(
        new FileOutputStream("output.txt", append), autoFlush);
System.setOut(out);

If append is true, the stream will append to an existing file instead of truncating it. If autoflush is true, the output buffer will be flushed whenever a byte array is written, one of the println methods is called, or a \n is written.

I'd just like to add that it is usually a better idea to use a logging subsystem like Log4j, Logback or the standard Java java.util.logging subsystem. These offer fine-grained logging control via runtime configuration files, support for rolling log files, feeds to system logging, and so on.

Alternatively, if you are not "logging" then consider the following:

• With typical shells, you can redirecting standard output (or standard error) to a file on the command line; e.g.

  $ java MyApp > output.txt   
  

  For more information, refer to a shell tutorial or manual entry.

• You could change your application to use an out stream passed as a method parameter or via a singleton or dependency injection rather than writing to System.out.

Changing System.out may cause nasty surprises for other code in your JVM that is not expecting this to happen. (A properly designed Java library will avoid depending on System.out and System.err, but you could be unlucky.)

May I suggest trying to use in else if statement in your if/else statement. And if you don't want to run any code that not under any conditions you want you can just leave the else out at the end of the statement. else if can also be used for any number of diversion paths that need things to be a certain condition for each.

if(condition 1){

} else if (condition 2) {

}else {

}

Instead of:

first_list = [1,2,3,4]
my_set=set(first_list)
my_list = list(my_set)

Why not shortcut the process:

my_list = list(set([1,2,3,4])

This will remove the dupes from you list and return a list back to you.

They have totally different meaning and aren't really related at all.

ORDER BY allows you to sort the result set according to different criteria, such as first sort by name from a-z, then sort by the price highest to lowest.

(ORDER BY name, price DESC)

GROUP BY allows you to take your result set, group it into logical groups and then run aggregate queries on those groups. You could for instance select all employees, group them by their workplace location and calculate the average salary of all employees of each workplace location.

You are most probably missing PATH entries in your windows. Follow this instruction : How do I set or change the PATH system variable?

As Oscar Wilde said

Consistency is the last refuge of the unimaginative.

R is more of an evolved rather than designed language, so these things happen. names() and colnames() work on a data.frame but names() does not work on a matrix:

R> DF <- data.frame(foo=1:3, bar=LETTERS[1:3])
R> names(DF)
[1] "foo" "bar"
R> colnames(DF)
[1] "foo" "bar"
R> M <- matrix(1:9, ncol=3, dimnames=list(1:3, c("alpha","beta","gamma")))
R> names(M)
NULL
R> colnames(M)
[1] "alpha" "beta"  "gamma"
R> 

Make use of Relative layout it will adjust the view so that you can see that view while typing the text

Use DISTINCT to remove duplicate GROUPING SETS from the GROUP BY clause

In a completely silly example using GROUPING SETS() in general (or the special grouping sets ROLLUP() or CUBE() in particular), you could use DISTINCT in order to remove the duplicate values produced by the grouping sets again:

SELECT DISTINCT actors
FROM (VALUES('a'), ('a'), ('b'), ('b')) t(actors)
GROUP BY CUBE(actors, actors)

With DISTINCT:

actors
------
NULL
a
b

Without DISTINCT:

actors
------
a
b
NULL
a
b
a
b

But why, apart from making an academic point, would you do that?

Use DISTINCT to find unique aggregate function values

In a less far-fetched example, you might be interested in the DISTINCT aggregated values, such as, how many different duplicate numbers of actors are there?

SELECT DISTINCT COUNT(*)
FROM (VALUES('a'), ('a'), ('b'), ('b')) t(actors)
GROUP BY actors

Answer:

count
-----
2

Use DISTINCT to remove duplicates with more than one GROUP BY column

Another case, of course, is this one:

SELECT DISTINCT actors, COUNT(*)
FROM (VALUES('a', 1), ('a', 1), ('b', 1), ('b', 2)) t(actors, id)
GROUP BY actors, id

With DISTINCT:

actors  count
-------------
a       2
b       1

Without DISTINCT:

actors  count
-------------
a       2
b       1
b       1

For more details, I've written some blog posts, e.g. about GROUPING SETS and how they influence the GROUP BY operation, or about the logical order of SQL operations (as opposed to the lexical order of operations).

The getRow() method retrieves the current row number, not the number of rows. So before starting to iterate over the ResultSet, getRow() returns 0.

To get the actual number of rows returned after executing your query, there is no free method: you are supposed to iterate over it.

Yet, if you really need to retrieve the total number of rows before processing them, you can:

1. ResultSet.last()
2. ResultSet.getRow() to get the total number of rows
3. ResultSet.beforeFirst()
4. Process the ResultSet normally

A slight improvement of the above accepted answer, that I think is more pythonic (asking for forgiveness is better than asking for permission)

column_widths = []
for row in workSheet.iter_rows():
    for i, cell in enumerate(row):
        try:
            column_widths[i] = max(column_widths[i], len(str(cell.value)))
        except IndexError:
            column_widths.append(len(str(cell.value)))

for i, column_width in enumerate(column_widths):
    workSheet.column_dimensions[get_column_letter(i + 1)].width = column_width

Use attribute binding syntax instead

<ol class="viewer-nav"><li *ngFor="let section of sections" 
    [attr.data-sectionvalue]="section.value">{{ section.text }}</li>  
</ol>

or

<ol class="viewer-nav"><li *ngFor="let section of sections" 
    attr.data-sectionvalue="{{section.value}}">{{ section.text }}</li>  
</ol>

Since you're using Spring, stick with Spring, don't hack it yourself like the other post posits.

The Spring manual says:

You shouldn't interact directly with the HttpSession for security purposes. There is simply no justification for doing so - always use the SecurityContextHolder instead.

The suggested best practice for accessing the session is:

Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();

if (principal instanceof UserDetails) {
  String username = ((UserDetails)principal).getUsername();
} else {
  String username = principal.toString();
}

The key here is that Spring and Spring Security do all sorts of great stuff for you like Session Fixation Prevention. These things assume that you're using the Spring framework as it was designed to be used. So, in your servlet, make it context aware and access the session like the above example.

If you just need to stash some data in the session scope, try creating some session scoped bean like this example and let autowire do its magic. :)

You can use jQuery click instead of using onclick attribute, Try the following:

$('table').on('click', 'input[type="button"]', function(e){
   $(this).closest('tr').remove()
})

If you want to avoid the semantic trouble of placing divs inside anchor tags, just place the anchor tag on the same level as the divs, wrap them all with a container with position: relative, make your anchor tag position: absolute and expand it to fill the container. Also if it's not on the end of the content flow make sure you throw a z-index in there to place it above the content.

As suggested I have added a markup code:

<div class="div__container>
  <div class="div__one>
  </div>
  <div class="div__two">
  </div>
  <a href="#"></a>
</div>

And the css:

.div__container {
  position: relative; 
}
.div__container a {
  position: absolute;
  top: 0;
  bottom: 0;      
  left: 0;
  right: 0;
  z-index: 999;
}

I use this method for purely counting how many lines in a file. What is the downside of doing this verses the other answers. I'm seeing many lines as opposed to my two line solution. I'm guessing there's a reason nobody does this.

$lines = count(file('your.file'));
echo $lines;

This wikipedia article provides the formulae and an example. The text is in german, but the calculations speak for themselves.

Should work in all cases:

SELECT regexp_replace(0.1234, '^(-?)([.,])', '\10\2') FROM dual

it's how I implemented it , the reason behind is if the class that you want to get the name from it's member is not static then you need to create an instanse of that and then get the member's name. so generic here comes to help

public static string GetName<TClass>(Expression<Func<TClass, object>> exp)
{
    MemberExpression body = exp.Body as MemberExpression;

    if (body == null)
    {
         UnaryExpression ubody = (UnaryExpression)exp.Body;
         body = ubody.Operand as MemberExpression;
    }

     return body.Member.Name;
}

the usage is like this

var label = ClassExtension.GetName<SomeClass>(x => x.Label); //x is refering to 'SomeClass'

They're apples and oranges. You don't want to compare them. They're two different things. AngularJs has already jQuery lite built in which allows you to perform basic DOM manipulation without even including the full blown jQuery version.

jQuery is all about DOM manipulation. It solves all the cross browser pain otherwise you will have to deal with but it's not a framework that allows you to divide your app into components like AngularJS.

A nice thing about AngularJs is that it allows you to separate/isolate the DOM manipulation in the directives. There are built-in directives ready for you to use such as ng-click. You can create your own custom directives that will contain all your view logic or DOM manipulation so you don't end up mingle DOM manipulation code in the controllers or services that should take care of the business logic.

Angular breaks down your app into - Controllers - Services - Views - etc.

and there is one more thing, that's the directive. It's an attribute you can attach to any DOM element and you can go nuts with jQuery within it without worrying about your jQuery ever conflicts with AngularJs components or messes up with its architecture.

I heard from a meetup I attended, one of the founders of Angular said they worked really hard to separate out the DOM manipulation so do not try to include them back in.

You just have to go to your Module settings > Project and specify a "Project compiler output" and make your modules inherit from project. (For that go to Modules > Paths > Inherit project.

This did the trick for me.

Use the function Contains from the strings package.

import (
    "strings"
)
strings.Contains("something", "some") // true

you can use this site to generate a proxy for you. it generates a class and can parse and validate your input JSON object.

If you are trying to find a View from your Fragment then try doing it like this:

int w = ((EditText)getActivity().findViewById(R.id.editText1)).getLayoutParams().width;

Sometimes this error comes because it's simply the wrong folder. :-(

It shall be the folder which contains the pom.xml.

According to last row on the Date and Time Patterns table of the Java 7 API

X Time zone ISO 8601 time zone -08; -0800; -08:00

For ISO 8601 time zone you should use:

• X for (-08 or Z),
• XX for (-0800 or Z),
• XXX for (-08:00 or Z);

so to parse your "2010-04-05T17:16:00Z" you can use either "yyyy-MM-dd'T'HH:mm:ssX" or "yyyy-MM-dd'T'HH:mm:ssXX" or "yyyy-MM-dd'T'HH:mm:ssXXX" .

    System.out.println(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssX").parse("2010-04-05T17:16:00Z"));
    System.out.println(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssXX").parse("2010-04-05T17:16:00Z"));
    System.out.println(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssXXX").parse("2010-04-05T17:16:00Z"));

will correctly print out 'Mon Apr 05 13:16:00 EDT 2010'

You are mixing the 2 different CASE syntaxes inappropriately.

Use this style (Searched)

  CASE  
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Or this style (Simple)

  CASE u.nnmu 
  WHEN '0' THEN mu.naziv_mesta
  WHEN '1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Not This (Simple but with boolean search predicates)

  CASE u.nnmu 
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

In MySQL this will end up testing whether u.nnmu is equal to the value of the boolean expression u.nnmu ='0' itself. Regardless of whether u.nnmu is 1 or 0 the result of the case expression itself will be 1

For example if nmu = '0' then (nnmu ='0') evaluates as true (1) and (nnmu ='1') evaluates as false (0). Substituting these into the case expression gives

 SELECT CASE  '0'
  WHEN 1 THEN '0'
  WHEN 0 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

if nmu = '1' then (nnmu ='0') evaluates as false (0) and (nnmu ='1') evaluates as true (1). Substituting these into the case expression gives

 SELECT CASE  '1'
  WHEN 0 THEN '0'
  WHEN 1 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

If you wanted to keep it with just HTML and CSS you can use CSS Variables. Keep in mind, css variables aren't supported in IE.

<div class="thumb" style="--background: url('images/img.jpg')"></div> 

.thumb {
    background-image: var(--background);
}

Using the wildcard * selector in CSS to override inheritance for all attributes of an element (by setting these back to their initial state).

An example of its use:

li * {
   display: initial;
}

The only problem with cnoremap w!! is that it replaces w with ! (and hangs until you type the next char) whenever you type w! at the : command prompt. Like when you want to actually force-save with w!. Also, even if it's not the first thing after :.

Therefore I would suggest mapping it to something like <Fn>w. I personally have mapleader = F1, so I'm using <Leader>w.

This is how I do :

<div class="jumbotron" style="background: url(img/bg.jpg) no-repeat center center fixed; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; background-size: cover;">_x000D_
  <h1>Hello</h1>_x000D_
</div>

Instance variable is the variable declared inside a class, but outside a method: something like:

class IronMan {

    /** These are all instance variables **/
    public String realName;
    public String[] superPowers;
    public int age;

    /** Getters and setters here **/
}

Now this IronMan Class can be instantiated in another class to use these variables. Something like:

class Avengers {

    public static void main(String[] a) {
        IronMan ironman = new IronMan();
        ironman.realName = "Tony Stark";
        // or
        ironman.setAge(30);
    }

}

This is how we use the instance variables. Shameless plug: This example was pulled from this free e-book here here.

With custom index:

$arr=array("a"=>"one", "b"=>"two");
    $arr=array("c"=>"three", "d"=>"four").$arr;

    print_r($arr);
    -------------------
    output:
    ----------------
    Array
    (
    [c]=["three"]
    [d]=["four"]
    [a]=["two"]
    [b]=["one"]
    )

It seems no one has mentioned about using nonNull method which also can be used with streams in Java 8 to remove null (but not empty) as:

String[] origArray = {"Apple", "", "Cat", "Dog", "", null};
String[] cleanedArray = Arrays.stream(firstArray).filter(Objects::nonNull).toArray(String[]::new);
System.out.println(Arrays.toString(origArray));
System.out.println(Arrays.toString(cleanedArray));

And the output is:

[Apple, , Cat, Dog, , null]

[Apple, , Cat, Dog, ]

If we want to incorporate empty also then we can define a utility method (in class Utils(say)):

public static boolean isEmpty(String string) {
        return (string != null && string.isEmpty());
    }

And then use it to filter the items as:

Arrays.stream(firstArray).filter(Utils::isEmpty).toArray(String[]::new);

I believe Apache common also provides a utility method StringUtils.isNotEmpty which can also be used.

Just use this acl cmd, next time the files inside var are created it will have the r/w/x permission for www-data user.

cd var 
rm -rf *
cd ..
setfacl -d -m u:www-data:rwx var

Cmd explanation:

setfacl -> Set acl command    
-d -> default behavior    
-m -> modify 
u:www-data: -> for user 
rwx -> adding permissions  
var -> on the folder

The documentation has been updated. My answer has substantial changes vs the accepted answer: I wanted to reflect documentation is up-to-date, and accepted answer has a few broken links.

Also, I didn't understand when the accepted answer said "it defaults to node server.js". I think the documentation clarifies the default behavior:

npm-start

Start a package

Synopsis

npm start [-- <args>]

Description

This runs an arbitrary command specified in the package's "start" property of its "scripts" object. If no "start" property is specified on the "scripts" object, it will run node server.js.

In summary, running npm start could do one of two things:

1. npm start {command_name}: Run an arbitrary command (i.e. if such command is specified in the start property of package.json's scripts object)
2. npm start: Else if no start property exists (or no command_name is passed): Run node server.js, (which may not be appropriate, for example the OP doesn't have server.js; the OP runs nodeapp.js )
3. I said I would list only 2 items, but are other possibilities (i.e. error cases). For example, if there is no package.json in the directory where you run npm start, you may see an error: npm ERR! enoent ENOENT: no such file or directory, open '.\package.json'

Try:

subprocess.call(['sudo', 'apach2ctl', 'restart'])

The subprocess needs to access the real stdin/out/err for it to be able to prompt you, and read in your password. If you set them up as pipes, you need to feed the password into that pipe yourself.

If you don't define them, then it grabs sys.stdout, etc...

Your student.h file only forward declares a struct named "Student", it does not define one. This is sufficient if you only refer to it through reference or pointer. However, as soon as you try to use it (including creating one) you will need the full definition of the structure.

In short, move your struct Student { ... }; into the .h file and use the .cpp file for implementation of member functions (which it has none so you don't need a .cpp file).

Java beans are special type of POJOs.

Specialities listed below with reason

This does not answer the original question, but as the question is highly ranked and linked for any ContextClassLoader query, I think it is important to answer the related question of when the context class loader should be used. Short answer: never use the context class loader! But set it to getClass().getClassLoader() when you have to call a method that is missing a ClassLoader parameter.

When code from one class asks to load another class, the correct class loader to use is the same class loader as the caller class (i.e., getClass().getClassLoader()). This is the way things work 99.9% of the time because this is what the JVM does itself the first time you construct an instance of a new class, invoke a static method, or access a static field.

When you want to create a class using reflection (such as when deserializing or loading a configurable named class), the library that does the reflection should always ask the application which class loader to use, by receiving the ClassLoader as a parameter from the application. The application (which knows all the classes that need constructing) should pass it getClass().getClassLoader().

Any other way to obtain a class loader is incorrect. If a library uses hacks such as Thread.getContextClassLoader(), sun.misc.VM.latestUserDefinedLoader(), or sun.reflect.Reflection.getCallerClass() it is a bug caused by a deficiency in the API. Basically, Thread.getContextClassLoader() exists only because whoever designed the ObjectInputStream API forgot to accept the ClassLoader as a parameter, and this mistake has haunted the Java community to this day.

That said, many many JDK classes use one of a few hacks to guess some class loader to use. Some use the ContextClassLoader (which fails when you run different apps on a shared thread pool, or when you leave the ContextClassLoader null), some walk the stack (which fails when the direct caller of the class is itself a library), some use the system class loader (which is fine, as long as it is documented to only use classes in the CLASSPATH) or bootstrap class loader, and some use an unpredictable combination of the above techniques (which only makes things more confusing). This has resulted in much weeping and gnashing of teeth.

When using such an API, first, try to find an overload of the method that accepts the class loader as a parameter. If there is no sensible method, then try setting the ContextClassLoader before the API call (and resetting it afterwards):

ClassLoader originalClassLoader = Thread.currentThread().getContextClassLoader();
try {
    Thread.currentThread().setContextClassLoader(getClass().getClassLoader());
    // call some API that uses reflection without taking ClassLoader param
} finally {
    Thread.currentThread().setContextClassLoader(originalClassLoader);
}

To add to the above: If interrupt is not working, you can restart the kernel.

Go to the kernel dropdown >> restart >> restart and clear output. This usually does the trick. If this still doesn't work, kill the kernel in the terminal (or task manager) and then restart.

Interrupt doesn't work well for all processes. I especially have this problem using the R kernel.

Another solution you can use is SQL Developer.

With it, you have the ability to import from a csv file (other delimited files are available).

Just open the table view, then:

• choose actions
• import data
• find your file
• choose your options.

You have the option to have SQL Developer do the inserts for you, create an sql insert script, or create the data for a SQL Loader script (have not tried this option myself).

Of course all that is moot if you can only use the command line, but if you are able to test it with SQL Developer locally, you can always deploy the generated insert scripts (for example).

Just adding another option to the 2 already very good answers.

As part of htmlAttributes,e.g.

Html.BeginForm(
    action, controller, FormMethod.Post, new { enctype="multipart/form-data"})

Or you can pass null for action and controller to get the same default target as for BeginForm() without any parameters:

Html.BeginForm(
    null, null, FormMethod.Post, new { enctype="multipart/form-data"})

int *generate_randomnumbers(int start, int end){
    int *res = malloc(sizeof(int)*(end-start));
    srand(time(NULL));
    for (int i= 0; i < (end -start)+1; i++){
        int r = rand()%end + start;
        int dup = 0;
        for (int j = 0; j < (end -start)+1; j++){
            if (res[j] == r){
                i--;
                dup = 1;
                break;
            }
        }
        if (!dup)
            res[i] = r;
    }
    return res;
}

In the HTTP request case, it is also and alternatively possible to paste the credentials (with password) directly into the url:

http://username:[email protected]/...

This will save the pain to give your credentials every times again. Simple modify your .git/config (the url).

• It means zero or multiple parameter of same data type.
• It must be the last parameter of the constructor or function.
• We can have only one of this type parameter in respective constructor or function.

Example 1:

public class quest1 {

    public quest1(String... mynum) {
        System.out.println("yee haa");
    }

    public static void main(String[] args) {
        quest1 q=new quest1();

        quest1 q1=new quest1("hello");

    }
}

Example 2:

public class quest1 {

    public quest1(int... at) {
        System.out.println("yee haa");
    }

    public quest1(String... at) {
        System.out.println("yee haa");
    }

    public static void main(String[] args) {
        quest1 q=new quest1("value");

        quest1 q1=new quest1(1);

    }

    public void name(String ... s) {

    }
}

output:

yee haa

yee haa

Your HTTP client disconnected.

This could have a couple of reasons:

• Responding to the request took too long, the client gave up
• You responded with something the client did not understand
• The end-user actually cancelled the request
• A network error occurred
• ... probably more

You can fairly easily emulate the behavior:

URL url = new URL("http://example.com/path/to/the/file");

int numberOfBytesToRead = 200;

byte[] buffer = new byte[numberOfBytesToRead];
int numberOfBytesRead = url.openStream().read(buffer);

You could do it like this:

cd /tmp
git clone /your/local/rep  # make a temp copy
cd rep
git rm -r *                # delete everything
cp -r /your/local/rep/* .  # get only the files you want
git add *                  # add them again
git status                 # everything but those copied will be removed
git commit -a -m 'deleting stuff'
cd /your/local/rep
git pull /tmp/rep          # now everything else has been removed

There's probably a oneliner for that…

Change it to:

<div style="background-color:black; overflow:hidden;" onmouseover="this.bgColor='white'">
<div style="float:left">hello</div>
<div style="float:right">world</div>
</div>

Basically the outer div only contains floats. Floats are removed from the normal flow. As such the outer div really contains nothing and thus has no height. It really is black but you just can't see it.

The overflow:hidden property basically makes the outer div enclose the floats. The other way to do this is:

<div style="background-color:black" onmouseover="this.bgColor='white'">
<div style="float:left">hello</div>
<div style="float:right">world</div>
<div style="clear:both></div>
</div>

Oh and just for completeness, you should really prefer classes to direct CSS styles.

You can upgrade your Java 7 version to 1.7.0_131-b31

For JRE 1.7.0_131-b31 in Oracle site :

TLSv1.2 and TLSv1.1 are now enabled by default on the TLS client end-points. This is similar behavior to what already happens in JDK 8 releases.

On the Mac version I was getting the error when trying to run JSON-Clojure.json.clj, which is the script to export a database table to JSON. To get it to work I had to download the latest Clojure JAR from http://clojure.org/ and then right-click on PHPStorm app in the Finder and "Show Package Contents". Then go to Contents in there. Then open the lib folder, and see a bunch of .jar files. Copy the clojure-1.8.0.jar file from the unzipped archive I downloaded from clojure.org into the aforementioned lib folder inside the PHPStorm.app/Contents/lib. Restart the app. Now it freaking works.

EDIT: You also have to put the JSR-223 script engine into PHPStorm.app/Contents/lib. It can be built from https://github.com/ato/clojure-jsr223 or downloaded from https://www.dropbox.com/s/jg7s0c41t5ceu7o/clojure-jsr223-1.5.1.jar?dl=0 .

Sub TEST()
Dim value1 As String
Dim value2 As String
value1 = ThisWorkbook.Sheets(1).Range("A1").Value 'value from sheet1
value2 = ThisWorkbook.Sheets(2).Range("A1").Value 'value from sheet2
If value1 = value2 Then ThisWorkbook.Sheets(2).Range("L1").Value = value1 'or 2
End Sub

This will compare two sheets cells values and if they match place the value on sheet 2 in column L.

You can simply use

int numberOfLetters = yourWord.Length;

or to be cool and trendy, use LINQ like this :

int numberOfLetters = yourWord.ToCharArray().Count();

and if you hate both Properties and LINQ, you can go old school with a loop :

int numberOfLetters = 0;
foreach (char letter in yourWord)
{
    numberOfLetters++;
}

There is actually a property for this in the CSS4 media query draft.

The ‘pointer’ media feature is used to query about the presence and accuracy of a pointing device such as a mouse. If a device has multiple input mechanisms, it is recommended that the UA reports the characteristics of the least capable pointing device of the primary input mechanisms. This media query takes the following values:

‘none’
- The input mechanism of the device does not include a pointing device.

‘coarse’
- The input mechanism of the device includes a pointing device of limited accuracy.

‘fine’
- The input mechanism of the device includes an accurate pointing device.

This would be used as such:

/* Make radio buttons and check boxes larger if we have an inaccurate pointing device */
@media (pointer:coarse) {
    input[type="checkbox"], input[type="radio"] {
        min-width:30px;
        min-height:40px;
        background:transparent;
    }
}

I also found a ticket in the Chromium project related to this.

Browser compatibility can be tested at Quirksmode. These are my results (22 jan 2013):

• Chrome/iOS: Doesn't work
• Safari/iOS6: Doesn't work

If you are using Eclipse then you can do this by specifying the required size for the particular application in its Run Configuration's VM Arguments as EX: -Xms128m -Xmx512m

Or if you want all applications running from your eclipse to have the same specified size then you can specify this in the eclipse.ini file which is present in your Eclipse home directory.

To get the size of the JVM during Runtime you can use Runtime.totalMemory() which returns the total amount of memory in the Java virtual machine, measured in bytes.

If you want to remove only one saved password, e.g. for "user1":

• Go to the saved password directory (*c:\Users\USERNAME\AppData\Roaming\Subversion\auth\svn.simple\*)
• You will find several files in this folder (named with hash value)
• Find the file which contains the username "user1", which you want to change (open it with Notepad).
• Remove the file.
• Next time you will connect to your SVN server, Tortoise will prompt you for new username and password.

result() returns Object type data. . . . result_array() returns Associative Array type data.

Databases are heavily optimized for common usage scenarios (and LIKE is one of those).

You won't find a faster way of doing your search if you want to stay on the DB-level.

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.

I wrote a class for that too. http://blog.another-d-mention.ro/programming/read-load-files-from-zip-in-javascript/ You can load basic assets such as javascript/css/images directly from the zip using class methods. Hope it helps

Write lock on shared local repository

I had this problem and none of above advises helped me. I was able to fetch everything correctly. But push always failed. It was a local repository located on windows directory with several clients working with it through VMWare shared folder driver. It appeared that one of the systems locked Git repository for writing. After stopping relevant VMWare system, which caused the lock everything repaired immediately. It was almost impossible to figure out, which system causes the error, so I had to stop them one by one until succeeded.

This code worked fine for me.

 import java.io.FileOutputStream;
 import java.io.IOException;
 import java.io.InputStream;
 import java.io.OutputStream;
 import java.net.URL;

public class SaveImageFromUrl {

public static void main(String[] args) throws Exception {
    String imageUrl = "http://www.avajava.com/images/avajavalogo.jpg";
    String destinationFile = "image.jpg";

    saveImage(imageUrl, destinationFile);
}

public static void saveImage(String imageUrl, String destinationFile) throws IOException {
    URL url = new URL(imageUrl);
    InputStream is = url.openStream();
    OutputStream os = new FileOutputStream(destinationFile);

    byte[] b = new byte[2048];
    int length;

    while ((length = is.read(b)) != -1) {
        os.write(b, 0, length);
    }

    is.close();
    os.close();
}

}

Update

For newer and still maintained library try jquery.floatThead (as mentioned by Bob Jordan in the comment) instead.

Old Answer

This is a very old answer, the library mentioned below no longer maintained.

I am using StickyTableHeaders on GitHub and it works like charm!

I had to add this css to make the header not transparent though.

table#stickyHeader thead {
  border-top: none;
  border-bottom: none;
  background-color: #FFF;
}

You need a mechanism which avoids busy-waiting. The old wait/notify mechanism is fraught with pitfalls so prefer something from the java.util.concurrent library, for example the CountDownLatch:

public final CountDownLatch latch = new CountDownLatch(1);

public void run () {
  latch.await();
  ...
}

And at the other side call

yourRunnableObj.latch.countDown();

However, starting a thread to do nothing but wait until it is needed is still not the best way to go. You could also employ an ExecutorService to which you submit as a task the work which must be done when the condition is met.

Another reason of this problem may be a missing library.

Go to Properties -> Android and check that you add the libraries correctly

If you just wanted to check whether flash is enabled, this should be enough.

function testFlash() {

    var support = false;

    //IE only
    if("ActiveXObject" in window) {

        try{
            support = !!(new ActiveXObject("ShockwaveFlash.ShockwaveFlash"));
        }catch(e){
            support = false;
        }

    //W3C, better support in legacy browser
    } else {

        support = !!navigator.mimeTypes['application/x-shockwave-flash'];

    }

    return support;

}

Note: avoid checking enabledPlugin, some mobile browser has tap-to-enable flash plugin, and will trigger false negative.

If I Understood correctly you need to view the .db file that you extracted from internal storage of Emulator. If that's the case use this

http://sourceforge.net/projects/sqlitebrowser/

to view the db.

You can also use a firefox extension

https://addons.mozilla.org/en-us/firefox/addon/sqlite-manager/

EDIT: For online tool use : https://sqliteonline.com/

From Application Manager, you can delete whole application with data. Or just data by it self. This includes database.

1. Navigate to Settings. You can get to the settings menu either in your apps menu or, on most phones, by pulling down the notification drawer and tapping a button there.

2. Select the Apps submenu. On some phones this menu will have a slightly different name such as Application Manager.

3. Swipe right to the All apps list. Ignore the lists of Running and Downloaded apps. You want the All apps list.

4. Select the app you wish to disable. A properties screen appears with a button for Force Stop on the upper left and another for either Disable or Uninstall updates on the upper right side.

5. Delete data.

    //load css first, then print <link> to header, and execute callback
    //just set var href above this..
    $.ajax({
          url: href,
          dataType: 'css',
          success: function(){                  
                $('<link rel="stylesheet" type="text/css" href="'+href+'" />').appendTo("head");
                //your callback
            }
    });

For Jquery 1.2.6 and above ( omitting the fancy attributes functions above ).

I am doing it this way because I think that this will ensure that your requested stylesheet is loaded by ajax before you try to stick it into the head. Therefore, the callback is executed after the stylesheet is ready.

You can use the --prefix option:

mkdir -p ./install/here/node_modules
npm install --prefix ./install/here <package>

The package(s) will then be installed in ./install/here/node_modules. The mkdir is needed since npm might otherwise choose an already existing node_modules directory higher up in the hierarchy. (See npm documentation on folders.)

Syntax:

CASE value WHEN [compare_value] THEN result 
[WHEN [compare_value] THEN result ...] 
[ELSE result] 
END

Alternative: CASE WHEN [condition] THEN result [WHEN [condition] THEN result ...]

I've had the same problem, our work environment is based on Eclipse Java projects, and we needed to build automatically an ANT file so that we could use a continuous integration server (Jenkins, in our case).

We rolled out our own Eclipse Java to Ant tool, which is now available on GitHub:

ant-build-for-java

To use it, call:

java -jar ant-build-for-java.jar <folder with repositories> [<.userlibraries file>]

The first argument is the folder with the repositories. It will search the folder recursively for any .project file. The tool will create a build.xml in the given folder.

Optionally, the second argument can be an exported .userlibraries file, from Eclipse, needed when any of the projects use Eclipse user libraries. The tool was tested only with user libraries using relative paths, it's how we use them in our repo. This implies that JARs and other archives needed by projects are inside an Eclipse project, and referenced from there.

The tool only supports dependencies from other Eclipse projects and from Eclipse user libraries.

I can't believe any of the many answers gives what I'd consider the "one obvious way to do it" (and I'm not even Dutch...!-) -- up to just below 24 hours' worth of seconds (86399 seconds, specifically):

>>> import time
>>> time.strftime('%H:%M:%S', time.gmtime(12345))
'03:25:45'

Doing it in a Django template's more finicky, since the time filter supports a funky time-formatting syntax (inspired, I believe, from PHP), and also needs the datetime module, and a timezone implementation such as pytz, to prep the data. For example:

>>> from django import template as tt
>>> import pytz
>>> import datetime
>>> tt.Template('{{ x|time:"H:i:s" }}').render(
...     tt.Context({'x': datetime.datetime.fromtimestamp(12345, pytz.utc)}))
u'03:25:45'

Depending on your exact needs, it might be more convenient to define a custom filter for this formatting task in your app.

I do not believe there is a way to do this strictly with CSS. The reason is your "important" qualifier to the question: forcing the parent element to expand with the contents of its child.

My guess is that you will have to use some bits of JavaScript to find the height of the child, and make adjustments.

So, with this HTML:

<div class="parentElement">  
  <div class="childElement">  
    ...Some Contents...  
  </div>  
</div>  

This CSS:

.parentElement {  
  position:relative;
  width:960px;
}
.childElement {
  position:absolute;
  top:50%;
  left:50%;
}

This jQuery might be useful:

$('.childElement').each(function(){
  // determine the real dimensions of the element: http://api.jquery.com/outerWidth/
  var x = $(this).outerWidth();
  var y = $(this).outerHeight();
  // adjust parent dimensions to fit child
  if($(this).parent().height() < y) {
    $(this).parent().css({height: y + 'px'});
  }
  // offset the child element using negative margins to "center" in both axes
  $(this).css({marginTop: 0-(y/2)+'px', marginLeft: 0-(x/2)+'px'});
});

Remember to load the jQ properly, either in the body below the affected elements, or in the head inside of $(document).ready(...).

INSERT INTO DestTable
SELECT * FROM SourceTable
WHERE ...

It's new features since the version 3.3.0 http://www.rabbitmq.com/release-notes/README-3.3.0.txt

...
25603 prevent access using the default guest/guest credentials except via
      localhost.

If you want enable the guest user read this or this RabbitMQ 3.3.1 can not login with guest/guest

# remove guest from loopback_users in rabbitmq.config like this
[{rabbit, [{loopback_users, []}]}].
# It is danger for default user and default password for remote access
# better to change password 
rabbitmqctl  change_password guest NEWPASSWORD

If you want create a new user with admin grants:

rabbitmqctl add_user test test
rabbitmqctl set_user_tags test administrator
rabbitmqctl set_permissions -p / test ".*" ".*" ".*"

Now you can access using test test.

I know this is an older question post, but my daughter came to me with the question, and referenced this page as having possible answers. Given that she's hunting an answer for this, it's a safe assumption others might still be as well.

All are great approaches, and as with everything there's about as many way to skin a cat as there are cats to skin.

If you're looking for a left trim and a right trim of a character or string, and your trailing character/string is uniform in length, here's my suggestion:

SELECT SUBSTRING(ColName,VAR, LEN(ColName)-VAR)

Or in this question...

SELECT SUBSTRING('"this is a test message"',2, LEN('"this is a test message"')-2)

With this, you simply adjust the SUBSTRING starting point (2), and LEN position (-2) to whatever value you need to remove from your string.

It's non-iterative and doesn't require explicit case testing and above all it's inline all of which make for a cleaner execution plan.

File extensions do not have any bearing or impact on the content of the file. You can hold YAML content in files with any extension: .yml, .yaml or indeed anything else.

The (rather sparse) YAML FAQ recommends that you use .yaml in preference to .yml, but for historic reasons many Windows programmers are still scared of using extensions with more than three characters and so opt to use .yml instead.

So, what really matters is what is inside the file, rather than what its extension is.

According the PostgreSQL documentation of the INSERT statement, handling the ON DUPLICATE KEY case is not supported. That part of the syntax is a proprietary MySQL extension.

You likely need to re-start VNC on both ends. i.e. when you say "restarted VNC", you probably just mean the client. But what about the other end? You likely need to re-start that end too. The root cause is likely a conflict. Many apps spy on the clipboard when they shouldn't. And many apps are not forgiving when they go to open the clipboard and can't. Robust ones will retry, others will simply not anticipate a failure and then they get fouled up and need to be restarted. Could be VNC, or it could be another app that's "listening" to the clipboard viewer chain, where it is obligated to pass along notifications to the other apps in the chain. If the notifications aren't sent, then VNC may not even know that there has been a clipboard update.

In case the above does not work for you (i.e.: you are working with new SQL or Azure) try the following:

1) drop existing column constraint (if any):

ALTER TABLE [table_name] DROP CONSTRAINT DF_my_constraint

2) create a new one:

ALTER TABLE [table_name] ADD CONSTRAINT DF_my_constraint  DEFAULT getdate() FOR column_name;

This is what I use:

var result = [];
for (var l in someObject){
  if (someObject.hasOwnProperty(l){
    result.push(l+': '+someObject[l]);
  }
}
alert(result.join('\n'));

If you want to show nested objects too, you could use something recursive:

function alertObject(obj){
 var result = [];
 function traverse(obj){
 for (var l in obj){
   if (obj.hasOwnProperty(l)){
     if (obj[l] instanceof Object){
       result.push(l+'=>[object]');
       traverse(obj[l]);
     } else {
       result.push(l+': '+obj[l]);
     }
   }
  }
 }
 traverse(obj);
 return result;
}

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

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

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

How to remove Node.js from Windows:

1. Take a deep breath.

2. Run npm cache clean --force

3. Uninstall from Programs & Features with the uninstaller.

4. Reboot (or you probably can get away with killing all node-related processes from Task Manager).

5. Look for these folders and remove them (and their contents) if any still exist. Depending on the version you installed, UAC settings, and CPU architecture, these may or may not exist:

   • C:\Program Files (x86)\Nodejs
   • C:\Program Files\Nodejs
   • C:\Users\{User}\AppData\Roaming\npm (or %appdata%\npm)
   • C:\Users\{User}\AppData\Roaming\npm-cache (or %appdata%\npm-cache)
   • C:\Users\{User}\.npmrc (and possibly check for that without the . prefix too)
   • C:\Users\{User}\AppData\Local\Temp\npm-*

6. Check your %PATH% environment variable to ensure no references to Nodejs or npm exist.

7. If it's still not uninstalled, type where node at the command prompt and you'll see where it resides -- delete that (and probably the parent directory) too.

8. Reboot, for good measure.

One possible explanation is a database trigger that fires for each DROP TABLE statement. To find the trigger, query the _TRIGGERS dictionary views:

select * from all_triggers
where trigger_type in ('AFTER EVENT', 'BEFORE EVENT')

disable any suspicious trigger with

   alter trigger <trigger_name> disable;

and try re-running your DROP TABLE statement

Use the Date property: Gets the date component of this instance.

var dateAndTime = DateTime.Now;
var date = dateAndTime.Date;

variable date contain the date and the time part will be 00:00:00.

or

Console.WriteLine(DateTime.Now.ToString("dd/MM/yyyy"));

or

DateTime.ToShortDateString Method-

Console.WriteLine(DateTime.Now.ToShortDateString ());

It seems to me you are using the wrong version...

                y = new_height - im.size[1]
            new_im.paste(im, (offset, y))
            offset += im.size[0]
        else:
            x = 0
            if aligment == 'center':
                x = int((new_width - im.size[0])/2)
            elif aligment == 'right':
                x = new_width - im.size[0]
            new_im.paste(im, (x, offset))
            offset += im.size[1]

    return new_im

It allows choosing a background color and image alignment. It's also easy to do recursion:

images = map(Image.open, ['hummingbird.jpg', 'tiger.jpg', 'monarch.png'])

combo_1 = append_images(images, direction='horizontal')
combo_2 = append_images(images, direction='horizontal', aligment='top',
                        bg_color=(220, 140, 60))
combo_3 = append_images([combo_1, combo_2], direction='vertical')
combo_3.save('combo_3.png')

try this if array[index] is null

if (array[index] != null) 

If you want the last 5 rows, ordered in ascending order, you need a subquery:

SELECT *
FROM
    ( SELECT id, name, form_id, DATE(updated_at) AS updated_date, updated_at
      FROM wp_frm_items
      WHERE user_id = 11 
        AND form_id=9
      ORDER BY updated_at DESC
      LIMIT 5
    ) AS tmp
ORDER BY updated_at

After reading the question for 10th time, this may be (just maybe) what you want. Order by Date descending and then order by time (on same date) ascending:

SELECT id, name, form_id, DATE(updated_at) AS updated_date
FROM wp_frm_items
WHERE user_id = 11 
  AND form_id=9
ORDER BY DATE(updated_at) DESC
       , updated_at ASC

$record = '123';

$this->db->distinct();

$this->db->select('accessid');

$this->db->where('record', $record); 

$query = $this->db->get('accesslog');

then

$query->num_rows();

should go a long way towards it.

Use:

create table new_table_name 
as
select column_name,[more columns] from Existed_table;

Example:

create table dept
as
select empno, ename from emp;

If the table already exists:

insert into new_tablename select columns_list from Existed_table;

I almost always just use overflow:hidden on my text-elements in those situations, it often works like a charm ;)

.post-container {
 margin: 20px 20px 0 0;
 border:5px solid #333;
}
.post-thumb img {
 float: left;
}
.post-content {
 overflow:hidden;
}

  Object.defineProperty(Results, "Active", {value : 'true',
                       writable : true,
                       enumerable : true,
                       configurable : true});

I agree with @haha on this one, for the most part. But there are several cross-browser related issues with using the "float:right" and could ultimately give you more of a headache than you want. If you know what the widths are going to be for each column use a float:left on both and save yourself the trouble. Another thing you can incorporate into your methodology is build column classes into your CSS.

So try something like this:

CSS

.col-wrapper{width:960px; margin:0 auto;}
.col{margin:0 10px; float:left; display:inline;}
.col-670{width:670px;}
.col-250{width:250px;}

HTML

<div class="col-wrapper">
    <div class="col col-670">[Page Content]</div>
    <div class="col col-250">[Page Sidebar]</div>
</div>

On Ubuntu 14.04 I had to use a combination of previous answers.

First, install pip3 apt-get install python-pip3

Then with pip3 install jupyter pip3 install jupyter

Then using ipython3 install the kernel ipython3 kernel install

If you meant to run foo() inside a python script every 10 seconds, you can do something on these lines.

import time

def foo():
    print "Howdy"

while True:
    foo()
    time.sleep(10)

Use Controls object

For i = 1 To X
    Controls("Label" & i).Caption =  MySheet.Cells(i + 1, i).Value
Next
