Programs & Examples On #.htaccess

Similar to Amir Forsati's solution htaccess redirect to https://www but for variable domain name, I suggest:

RewriteEngine on
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ^(www\.)?(.+)$ [NC]
RewriteRule ^ https://www.%2%{REQUEST_URI} [R=301,L]

If you want to see only fatal runtime errors:

php_value display_errors on
php_value error_reporting 4

I had the same problem, and found a detailed explanation in http://www.webmasterworld.com/apache/3163397.htm

My solution (the subdomains contents should be in a folder called sd_subdomain:

Options +FollowSymLinks -MultiViews

RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} !^www\.
RewriteCond %{HTTP_HOST} subdomain\.domain\.com
RewriteCond $1 !^sd_
RewriteRule (.*) /sd_subdomain/$1 [L]

You can think it like php.ini files sub files.. php.ini file stores most of the configuration about php like curl enable disable. Where .htaccess makes this setting only for perticular directory and php.ini file store settings for its server' all directory...

I agree with @TheAlpha's accepted answer, Apache reads the DirectoryIndex target files from left to right , if the first file exists ,apche serves it and if it doesnt then the next file is served as an index for the directory. So if you have the following Directive :

DirectoryIndex file1.html file2.html

Apache will serve /file.html as index ,You will need to change the order of files if you want to set /file2.html as index

DirectoryIndex file2.html file1.html

You can also set index file using a RewriteRule

RewriteEngine on

RewriteRule ^$ /index.html [L]

RewriteRule above will rewrite your homepage to /index.html the rewriting happens internally so http://example.com/ would show you the contents ofindex.html .

I came up with the solution and posted it on my blog

http://web.archive.org/web/20130310123646/http://onlinemarketingexperts.com.au/2013/01/how-to-permanently-redirect-301-all-404-missing-pages-in-htaccess/

here is the htaccess code also

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . / [L,R=301]

but I posted other solutions on my blog too, it depends what you need really

You can also use RedirectMatch directive to deny access to a folder.

To deny access to a folder, you can use the following RedirectMatch in htaccess :

 RedirectMatch 403 ^/folder/?$

This will forbid an external access to /folder/ eg : http://example.com/folder/ will return a 403 forbidden error.

To deny access to everything inside the folder, You can use this :

RedirectMatch 403 ^/folder/.*$

This will block access to the entire folder eg : http://example.com/folder/anyURI will return a 403 error response to client.

Try to disable the engine option in your .htaccess file:

php_flag engine off

Place the below line in your .htaccess file and replace the file name as you wish

RewriteRule ^(test\.php) - [F,L,NC]

If you have MAMP PRO you can set up a host like mysite.local, then add some options from the 'Advanced' panel in the main window. Just switch on the options 'Indexes' and 'MultiViews'. 'Includes' and 'FollowSymLinks' should already be checked.

To remove the .html extension from your URLs, you can use the following code in root/htaccess :

#mode_rerwrite start here

RewriteEngine On

# does not apply to existing directores, meaning that if the folder exists on server then don't change anything and don't run the rule.

RewriteCond %{REQUEST_FILENAME} !-d

#Check for file in directory with .html extension 

RewriteCond %{REQUEST_FILENAME}\.html !-f

#Here we actually show the page that has .html extension

RewriteRule ^(.*)$ $1.html [NC,L]

Thanks

try this:

<IfModule mod_headers.c>
     Header set Access-Control-Allow-Credentials true
     Header set Access-Control-Allow-Origin "your domain"
     Header set Access-Control-Allow-Headers "X-Requested-With"
</IfModule>

It's preferable to allow a list of know trusted host.

With some web hosts including NameCheap, it's not possible to disable ModSecurity using .htaccess. The only option is to contact tech support and ask them to alter the configuration for you.

I am using something like this - codeigniter-htaccess-file, its a good article to begin with.

• leave the .htaccess file in CI root dir
• make sure that mod_rewrite is on
• check for typos (ie. controller file/class name)
• in /application/config/config.php set $config['index_page'] = "";
• in /application/config/routes.php set your default controller $route['default_controller']="home";

If you are running clean installation of CI (2.1.3) there isn't really much that could be wrong.

• 2 config files
• controller
• .htaccess
• mod_rewrite

• Codeigniter .htaccess
• redirect-index-php-in-codeigniter

if it related to hosting site then ask to your hosting to enable url writing or if you want to enable it in local machine then check this youtube step by step tutorial related to enabling rewrite module in wamp apache https://youtu.be/xIspOX9FuVU?t=1m43s
Wamp server icon -> Apache -> Apache Modules and check the rewrite module option it should be checked Note its very important that after enable rewrite module you should require to restart all services of wamp server

Try this methode to redirect all to homepage new domain, Its works for me:

RewriteCond %{HTTP_HOST} ^olddomain\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.olddomain\.com$
RewriteRule ^(.*)$ "https\:\/\/newdomain\.com\/" [R=301,L]

To complement Jon Lin's answer, here is a no-trailing-slash technique that also works if the website is located in a directory (like example.org/blog/):

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [R=301,L]

For the sake of completeness, here is an alternative emphasizing that REQUEST_URI starts with a slash (at least in .htaccess files):

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} /(.*)/$
RewriteRule ^ /%1 [R=301,L] <-- added slash here too, don't forget it

Just don't use %{REQUEST_URI} (.*)/$. Because in the root directory REQUEST_URI equals /, the leading slash, and it would be misinterpreted as a trailing slash.

If you are interested in more reading:

• PR 3145 for Laravel
• A discussion on commit 343c31e

(update: this technique is now implemented in Laravel 5.5)

There isn't a direct 1:1 equivalent.

You can password protect a folder or file using file system permissions. If you are using ASP.Net you can also use some of its built in functions to protect various urls.

If you are trying to port .htaccess files used for url rewriting, check out ISAPI Rewrite: http://www.isapirewrite.com/

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^http://(www\.)?localhost.*$ [NC] 
RewriteCond %{REQUEST_URI} !^http://(www\.)?localhost/(.*)\.(gif|jpg|png|jpeg|mp4)$ [NC] 
RewriteRule . - [F]

try:

RewriteRule ^/apple(.*)?$ /folder1$1 [NC]

Where the folder you want to appear in the url is in the first part of the statement - this is what it will match against and the second part 'rewrites' it to your existing folder. the [NC] flag means that it will ignore case differences eg Apple/ will still forward.

See here for a tutorial: http://www.sitepoint.com/article/guide-url-rewriting/

There is also a nice test utility for windows you can download from here: http://www.helicontech.com/download/rxtest.zip Just to note for the tester you need to leave out the domain name - so the test would be against /folder1/login.php

to redirect from /folder1 to /apple try this:

RewriteRule ^/folder1(.*)?$ /apple$1 [R]

to redirect and then rewrite just combine the above in the htaccess file:

RewriteRule ^/folder1(.*)?$ /apple$1 [R]
RewriteRule ^/apple(.*)?$ /folder1$1 [NC]

well, there are two way to change max_execution_time.
1. You can directly set it in php.ini file.
2. Secondly, you can add following line in your code.

ini_set('max_execution_time', '100')

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.

Just Follow Simple 1-2-3 Steps :

1) Go to Taskbar

2) Click on WAMP icon (Left Click)

3) Now Go to Apache > Services > Apache Module and check Rewrite_module is enable or not ! if its not then click on it ! WAMP will be automatically restarted and you're done !

For Ubuntu,
First, run this command :-

sudo a2enmod rewrite

Then, edit the file /etc/apache2/sites-available/000-default.conf using nano or vim using this command :-

sudo nano /etc/apache2/sites-available/000-default.conf

Then in the 000-default.conf file, add this after the line DocumentRoot /var/www/html. If your root html directory is something other, then write that :-

<Directory "/var/www/html">
  AllowOverride All
</Directory>

After doing everything, restart apache using the command sudo service apache2 restart

Try this, I used it in many websites, it works perfectly

Options +FollowSymLinks
RewriteEngine On
RewriteCond %{HTTP_HOST} ^bewebdeveloper.com$
RewriteRule ^(.*) http://www.bewebdeveloper.com/$1  [QSA,L,R=301]

try this, it work for me

<IfModule mod_rewrite.c>

# Enable Rewrite Engine
# ------------------------------
RewriteEngine On
RewriteBase /

# Redirect index.php Requests
# ------------------------------
RewriteCond %{THE_REQUEST} ^GET.*index\.php [NC]
RewriteCond %{THE_REQUEST} !/system/.*
RewriteRule (.*?)index\.php/*(.*) /$1$2 [R=301,L]

# Standard ExpressionEngine Rewrite
# ------------------------------
RewriteCond $1 !\.(css|js|gif|jpe?g|png) [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]

</IfModule>

if you are having the

Allow from All

in httpd.conf then make sure us have

index.php

like in the below line in httpd.conf

DirectoryIndex index.html index.php

After doing that don't forget to change your href in, <a href="{the chosen redirected name}"> home</a>

Example:

.htaccess file

RewriteEngine On

RewriteRule ^about/$ /about.php

PHP file:

<a href="about/"> about</a>

This will capture requests for files like version, release, and README.md, etc. which should be treated either as endpoints, if defined (as in the case of /release), or as "not found."

The correct answer is

Options -Indexes

You must have been thinking of

AllowOverride All

https://httpd.apache.org/docs/2.2/howto/htaccess.html

.htaccess files (or "distributed configuration files") provide a way to make configuration changes on a per-directory basis. A file, containing one or more configuration directives, is placed in a particular document directory, and the directives apply to that directory, and all subdirectories thereof.

You could also use a RewriteRule if you wanted the ability to template match and redirect urls.

Hopefully people will find this answer as there are many, many posts about this on the web. Many people suggested it was an .htaccess problem, and for me it was. However, I had been looking in the .htaccess in the root, not in the .htaccess in the wp-admin folder. Normally, I work on this site in particular through terminal services, so when it booted me and I couldn't log back in, I was trying to access it from my home computer (and it's IP).

Silly me forgot the IP restriction I had placed in the wp-admin .htaccess file.

AuthName "Protected"
AuthType Basic
<Limit GET POST>
order deny,allow
deny from all
allow from 11.11.11.11
</Limit> 

If you have something like this in your wp-admin .htaccess files, that would easily explain why all the sites you work on ceased to function at the same time. Internet providers occasionally rotate IPs so that nobody is running a server from home without paying for it.

You can also deny access to a folder using RedirectMatch

Add the following line to htaccess

RedirectMatch 403 ^/folder/?$

This will return a 403 forbidden error for the folder ie : http://example.com/folder/ but it doest block access to files and folders inside that folder, if you want to block everything inside the folder then just change the regex pattern to ^/folder/.*$ .

Another option is mod-rewrite If url-rewrting-module is enabled you can use something like the following in root/.htaccss :

RewriteEngine on

RewriteRule ^folder/?$ - [F,L]

This will internally map a request for the folder to forbidden error page.

+ Copy .htaccess from Application to Root folder
+ edit .htaccess and put

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /ci_test/

    #Removes access to the system folder by users.
    #Additionally this will allow you to create a System.php controller,
    #previously this would not have been possible.
    #'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #When your application folder isn't in the system folder
    #This snippet prevents user access to the application folder
    #Submitted by: Fabdrol
    #Rename 'application' to your applications folder name.
    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #Checks to see if the user is attempting to access a valid file,
    #such as an image or css document, if this isn't true it sends the
    #request to index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
    # If we don't have mod_rewrite installed, all 404's
    # can be sent to index.php, and everything works as normal.
    # Submitted by: ElliotHaughin

    ErrorDocument 404 /index.php
</IfModule>

Note: make sure your web server is enable for  "rewrite_module"

+ Remove index.php from $config['index_page'] = 'index.php';
- edit config.php in application/config
- search for index.php
change it from  $config['index_page'] = 'index.php'; to  $config['index_page'] = '';

I'm afraid Aularon didn't provide enough steps to complete the process. With a little trial and error, I was able to successfully enable Gzipping on my dedicated WHM server.

Below are the steps:

• Run EasyApache within WHM, select Deflate within the Exhaustive Options list, and rebuild the server.

• Once done, goto Services Configuration >> Apache Configuration >> Include Editor >> Post VirtualHost Include, select All Versions, and then paste the mod_headers.c and mod_headers.c code (listed above in Aularon's post) on top of on another within the input field.

• Once saved, I was seeing a 75.36% data savings on average! You can run a before and after test by using this HTTP Compression tool to see your own results: http://www.whatsmyip.org/http_compression/

Hope this works for you all!

I use javascript encodeURI() function for the URL part that has forward slashes that should be seen as characters instead of http address. Eg:

"/api/activites/" + encodeURI("?categorie=assemblage&nom=Manipulation/Finition")

see http://www.w3schools.com/tags/ref_urlencode.asp

The solution is to create the php.ini file under your root directory. If the site is the wordpress installation then create the php.ini under your/path/to/wordpress/wp-admin/php.ini and add the following line of codes

[PHP]
post_max_size=120M
upload_max_filesize=132M

The difference between http and https is that https requests are sent over an ssl-encrypted connection. The ssl-encrypted connection must be established between the browser and the server before the browser sends the http request.

Https requests are in fact http requests that are sent over an ssl encrypted connection. If the server rejects to establish an ssl encrypted connection then the browser will have no connection to send the request over. The browser and the server will have no way of talking to each other. The browser will not be able to send the url that it wants to access and the server will not be able to respond with a redirect to another url.

So this is not possible. If you want to respond to https links, then you need an ssl certificate.

I've used this:

RewriteEngine On

# Unless directory, remove trailing slash
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/$ http://example.com/folder/$1 [R=301,L]

# Redirect external .php requests to extensionless URL
RewriteCond %{THE_REQUEST} ^(.+)\.php([#?][^\ ]*)?\ HTTP/
RewriteRule ^(.+)\.php$ http://example.com/folder/$1 [R=301,L]

# Resolve .php file for extensionless PHP URLs
RewriteRule ^([^/.]+)$ $1.php [L]

See also: this question

RewriteEngine On

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

RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]

This worked for me after much trial and error. Part one is from the user above and will capture www.xxx.yyy and send to https://xxx.yyy

Part 2 looks at entered URL and checks if HTTPS, if not, it sends to HTTPS

Done in this order, it follows logic and no error occurs.

HERE is my FULL version in side htaccess with WordPress:

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

RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]


# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Agree that

Options -Indexes

should work if the main server is configured to allow option overrides, but if not, this will hide all files from the listing (so every directory appears empty):

IndexIgnore *

Mainly If you are using Linux Based system Like 'Ubuntu' and this is only suggested for localhost user not for the server.

Follow all the steps mentioned in the previous answers. +

Check in Apache configuration for it. (AllowOverride All) If AllowOverride value is none then change it to All and restart apache again.

<Directory /var/www/>
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>

Let me know if this step help anyone. As it can save you time if you find it earlier.

I am adding the exact lines from my htaccess file in localhost. for your reference

Around line number 110

<IfModule mod_rewrite.c>

############################################
## enable rewrites

Options +FollowSymLinks
RewriteEngine on

############################################
## you can put here your magento root folder
## path relative to web root

#RewriteBase /

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

Images are for some user who understand easily from image the from the text:

Instead of passing a variable around I do this which is self-contained at the top of any page you don't want direct access to, this should still be paired with .htaccess rules but I feel safer knowing there is a fail-safe if htaccess ever gets messes up.

<?php
// Security check: Deny direct file access; must be loaded through index
if (count(get_included_files()) == 1) {
    header("Location: index.php"); // Send to index
    die("403"); // Must include to stop PHP from continuing
}
?>

The best way to do this is disable it with webserver apache2. In my Ubuntu 14.X - open /etc/apache2/apache2.conf change from

<Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

to

<Directory /var/www/>
        Options FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

then restart apache by:

sudo service apache2 reload

This will disable directory listing from all folder that apache2 serves.

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 had a problem with redirection also. I tried everything that was proposed on Stackoverflow. The one case I found by myself is:

RewriteEngine on
RewriteBase /
RewriteCond %{HTTP:SSL} !=1 [NC]
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

I believe this excerpt from the Apache documentation, complements well the previous answers :

This directive is required when you use a relative path in a substitution in per-directory (htaccess) context unless either of the following conditions are true:

• The original request, and the substitution, are underneath the DocumentRoot (as opposed to reachable by other means, such as Alias).

• The filesystem path to the directory containing the RewriteRule, suffixed by the relative substitution is also valid as a URL path on the server (this is rare).

As previously mentioned, in other contexts, it is only useful to make your rule shorter. Moreover, also as previously mentioned, you can achieve the same thing by placing the htaccess file in the subdirectory.

On Dreamhost Servers you can refer to this page that at time of writing indicates you may use the following for php 7.2 with FastCGI:

AddHandler fcgid-script .html
FcgidWrapper "/dh/cgi-system/php72.cgi" .html

Or if you are using php5 cgi (not FastCGI):

AddHandler php5-cgi .html

This code works for me

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

In conf/extra/httpd-vhosts.conf, add the line AllowOverride All for all the websites that you are having problem with

<VirtualHost example.site:80>
    # rest of the stuff
    <Directory "c:\Projects\example.site">
        Require all granted
         AllowOverride All <-----This line is required
    </Directory>
</VirtualHost>

Make sure that the htaccess file is readable by apache:

chmod 644 /var/www/abc/.htaccess 

And make sure the directory it's in is readable and executable:

chmod 755 /var/www/abc/

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

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

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

Give permission in .htaccess as follows:

<Directory "Your directory path/uploads/">
Allow from all
</Directory>

We used the following mod_rewrite rule:

RewriteEngine on
RewriteCond %{REQUEST_URI} !^/test/
RewriteCond %{REQUEST_URI} !^/my-folder/
RewriteRule (.*) http://www.newdomain.com/$1 [R=301,L]

This redirects (permanently with a 301 redirect) all traffic to the site to http://www.newdomain.com, except requests to resources in the /test and /my-folder directories. We transfer the user to the exact resource they requested by using the (.*) capture group and then including $1 in the new URL. Mind the spaces.

In your particular case the issue seem to be with accessing the site from non-canonical url (www.site.com vs. site.com).

Instead of fixing CORS issue (which may require writing proxy to server fonts with proper CORS headers depending on service provider) you can normalize your Urls to always server content on canonical Url and simply redirect if one requests page without "www.".

Alternatively you can upload fonts to different server/CDN that is known to have CORS headers configured or you can easily do so.

I found all solutions listed on this Q&A did not work for me, unfortunately. What did work was:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule . index.php [L]

RewriteCond %{HTTP_HOST} ^example\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.example\.com$
RewriteRule ^/?$ "https\:\/\/www\.example\.com\/" [R=301,L]
</IfModule>
# End Wordpress

Note, the above Wordpress rules are for Wordpress in multi user network mode. If your Wordpress is in single site mode, you would use:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

RewriteCond %{HTTP_HOST} ^example\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.example\.com$
RewriteRule ^/?$ "https\:\/\/www\.example\.com\/" [R=301,L]
</IfModule>
# End Wordpress

Make sure you use the percent sign in front of variables, not the dollar sign.

It's %{HTTP_HOST}, not ${HTTP_HOST}. There will be nothing in the error_log, there will be no Internal Server Errors, your regexp is still correct, the rule will just not match. This is really hideous if you work with django / genshi templates a lot and have ${} for variable substitution in muscle memory.

This is a quite confusing way of using Apache configuration directives.

Technically, the first bit is equivalent to

Allow From All

This is because Order Deny,Allow makes the Deny directive evaluated before the Allow Directives. In this case, Deny and Allow conflict with each other, but Allow, being the last evaluated will match any user, and access will be granted.

Now, just to make things clear, this kind of configuration is BAD and should be avoided at all cost, because it borders undefined behaviour.

The Limit sections define which HTTP methods have access to the directory containing the .htaccess file.

Here, GET and POST methods are allowed access, and PUT and DELETE methods are denied access. Here's a link explaining what the various HTTP methods are: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html

However, it's more than often useless to use these limitations as long as you don't have custom CGI scripts or Apache modules that directly handle the non-standard methods (PUT and DELETE), since by default, Apache does not handle them at all.

It must also be noted that a few other methods exist that can also be handled by Limit, namely CONNECT, OPTIONS, PATCH, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.

The last bit is also most certainly useless, since any correctly configured Apache installation contains the following piece of configuration (for Apache 2.2 and earlier):

#
# The following lines prevent .htaccess and .htpasswd files from being 
# viewed by Web clients. 
#
<Files ~ "^\.ht">
    Order allow,deny
    Deny from all
    Satisfy all
</Files>

which forbids access to any file beginning by ".ht".

The equivalent Apache 2.4 configuration should look like:

<Files ~ "^\.ht">
    Require all denied
</Files>

Not answering OPs question directly, but for the people finding this question in search of clarity on what's the difference between allow,deny and deny,allow:

Read the comma as a "but".

• allow but deny: whitelist with exceptions.
  everything is denied, except items on the allow list, except items on the deny list
• deny but allow: blacklist with exceptions.
  everything is allowed, except items on the deny list, except items on the allow list

allow only one country access, but exclude proxies within this country

OP needed a whitelist with exceptions, therefore allow,deny instead of deny,allow

When we apply local url, ErrorDocument directive expect the full path from DocumentRoot. There fore,

 ErrorDocument 404 /yourfoldernames/errors/404.html

You can use the following to refresh the page by clicking the back button:

window.addEventListener('popstate', () => {
  location.reload();
}, false);

This worked for me

PHP 7.2

AddHandler application/x-httpd-ea-php72 .php .php7 .phtml

PHP 7.3

AddHandler application/x-httpd-ea-php73 .php

First of all go to apache/bin/conf/httpd.conf and make sure that mod_deflate.so is enabled.

Then go to the .htaccess file and add this line:

SetOutputFilter DEFLATE

This should output all the content served as gzipped, i have tried it and it works.

The No input file specified is a message you are presented with because of the implementation of PHP on your server, which in this case indicates a CGI implementation (can be verified with phpinfo()).

Now, to properly explain this, you need to have some basic understanding on how your system works with URL's. Based on your .htaccess file, it seems that your CMS expects the URL to passed along as a PATH_INFO variable. CGI and FastCGI implementations do not have PATH_INFO available, so when trying to pass the URI along, PHP fails with that message.

We need to find an alternative.

One option is to try and fix this. Looking into the documentation for core php.ini directives you can see that you can change the workings for your implementation. Although, GoDaddy probably won't allow you to change PHP settings on a shared enviroment.

We need to find an alternative to modifying PHP settings
Looking into system/uri.php on line 40, you will see that the CMS attempts two types of URI detection - the first being PATH_INFO, which we just learned won't work - the other being the REQUEST_URI.

This should basically, be enough - but the parsing of the URI passed, will cause you more trouble, as the URI, which you could pass to REQUEST_URI variable, forces parse_url() to only return the URL path - which basically puts you back to zero.

Now, there's actually only one possibilty left - and that's changing the core of the CMS. The URI detection part is insufficient.

Add QUERY_STRING to the array on line 40 as the first element in system/uri.php and change your .htaccess to look like this:

RewriteEngine On 

RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d 

RewriteRule ^(.*)$ index.php?/$1 [L]

This will pass the URI you request to index.php as QUERY_STRING and have the URI detection to find it.

This, on the other hand, makes it impossible to update the CMS without changing core files till this have been fixed. That sucks...

. (dot) files are hidden by default on Unix/Linux systems. Most likely, if you know they are .htaccess files, then they are probably in the root folder for the website.

If you are using a command line (terminal) to access, then they will only show up if you use:

ls -a

If you are using a GUI application, look for a setting to "show hidden files" or something similar.

If you still have no luck, and you are on a terminal, you can execute these commands to search the whole system (may take some time):

cd /
find . -name ".htaccess"

This will list out any files it finds with that name.

Based on the example here: http://drupal.org/node/550488

The following will probably work in .htaccess

 <IfModule mod_expires.c>
   # Enable expirations.
   ExpiresActive On

   # Cache all files for 2 weeks after access (A).
   ExpiresDefault A1209600

  <FilesMatch (\.js|\.html)$>
     ExpiresActive Off
  </FilesMatch>
 </IfModule>

Goto your_severpath/apache_ver/conf/ Open the file httpd.conf in Notepad.

Find this line:

#LoadModule vhost_alias_module modules/mod_vhost_alias.so

Remove the hash symbol:

LoadModule vhost_alias_module modules/mod_vhost_alias.so

Then goto <Directory />

and change to:

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
</Directory>

Then restart your local server.

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

Similarly, if you wanted to redirect to a sub-folder instead of a sub-domain, do the following:

Working off of Kevin's great solution you can add this to the .htaccess file in your site's root directory:

    <IfModule mod_rewrite.c>
        RewriteBase /
        RewriteEngine On

        # Check if mobile=1 is set and set cookie 'mobile' equal to 1
        RewriteCond %{QUERY_STRING} (^|&)mobile=1(&|$)
        RewriteRule ^ - [CO=mobile:1:%{HTTP_HOST}]

        # Check if mobile=0 is set and set cookie 'mobile' equal to 0
        RewriteCond %{QUERY_STRING} (^|&)mobile=0(&|$)
        RewriteRule ^ - [CO=mobile:0:%{HTTP_HOST}]

        # cookie can't be set and read in the same request so check
        RewriteCond %{QUERY_STRING} (^|&)mobile=0(&|$)
        RewriteRule ^ - [S=1]

        # Check if this looks like a mobile device
        RewriteCond %{HTTP:x-wap-profile} !^$ [OR]
        RewriteCond %{HTTP_USER_AGENT} "android|blackberry|ipad|iphone|ipod|iemobile|opera mobile|palmos|webos|googlebot-mobile" [NC,OR]
        RewriteCond %{HTTP:Profile}       !^$

        # Check if we're not already on the mobile site
        RewriteCond %{HTTP_HOST}          !^m\.
        # Check to make sure we haven't set the cookie before
        RewriteCond %{HTTP:Cookie}        !\mobile=0(;|$)
        # Now redirect to the mobile site
        RewriteRule ^ http://www.mysite.com/m/ [R]
    </IfModule>

Then, in the /m/ folder, add or create an .htaccess with the following:

    #Begin user agent loop fix

         RewriteEngine Off
         RewriteBase /

    #End user agent loop fix 

I know it's not a direct answer to the question, but somebody (like me) might stumble upon this question and wonder how that method would be accomplished as well.

Try

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

RewriteEngine on
RewriteCond %{HTTP_HOST} ^(www\.)?olddomain\.com$ [NC]
RewriteRule ^(.*)$ "http://www.thenewdomain.com/" [R=301,L]

This is a common problem with GoDaddy virtual server hosting when you bring up a new website.

Assuming you have SSH access to the server (you have to enable it on cPanel), login to your account. Upon successful login, you will be placed in the home directory for your account. The DocumentRoot for your website is located in a subdirectory named public_html. GoDaddy defaults the permissions for this directory to 750, but those permissions are inadequate to allow Apache to read the files for website. You need to change the permissions for this directory to 755 (chmod 755 public_html).

Copy the files for your website into the public_html directory (both scp and rsync work for copying files to a GoDaddy Linux server).

Next, make sure all of the files under public_html are world readable. To do this, use this command:

cd public_html
chmod -R o+r *

If you have other subdirectories (like css, js, and img), make sure they are world accessible by enabling both read and execute for world access:

chmod o+rx css
chmod o+rx img
chmod o+rx js

Last, you will need to have a .htaccess file in the public_html file. GoDaddy enforces a rule that prohibits the site for loading if you do not have a .htaccess file in your public_html directory. You can use vi to create this file ("vi .htaccess"). Enter the following lines in the file:

Order allow,deny
Allow from all
Require all granted

This config will work for both Apache 2.2 and Apache 2.4. Save the file (ZZ), and then make sure the file has permissions of 644:

chmod 644 .htaccess

Works like a charm.

It is not possible to use relative paths for AuthUserFile:

File-path is the path to the user file. If it is not absolute (i.e., if it doesn't begin with a slash), it is treated as relative to the ServerRoot.

You have to accept and work around that limitation.

We're using IfDefine together with an apache2 command line parameter:

.htaccess (suitable for both development and live systems):

<IfDefine !development>
  AuthType Basic
  AuthName "Say the secret word"
  AuthUserFile /var/www/hostname/.htpasswd
  Require valid-user
</IfDefine>

Development server configuration (Debian)

Append the following to /etc/apache2/envvars:

export APACHE_ARGUMENTS=-Ddevelopment

Restart your apache afterwards and you'll get a password prompt only when you're not on the development server.

You can of course add another IfDefine for the development server, just copy the block and remove the !.

You can essentially do this 2 ways:

The .htaccess route with mod_rewrite

Add a file called .htaccess in your root folder, and add something like this:

RewriteEngine on
RewriteRule ^/?Some-text-goes-here/([0-9]+)$ /picture.php?id=$1

This will tell Apache to enable mod_rewrite for this folder, and if it gets asked a URL matching the regular expression it rewrites it internally to what you want, without the end user seeing it. Easy, but inflexible, so if you need more power:

The PHP route

Put the following in your .htaccess instead: (note the leading slash)

FallbackResource /index.php

This will tell it to run your index.php for all files it cannot normally find in your site. In there you can then for example:

$path = ltrim($_SERVER['REQUEST_URI'], '/');    // Trim leading slash(es)
$elements = explode('/', $path);                // Split path on slashes
if(empty($elements[0])) {                       // No path elements means home
    ShowHomepage();
} else switch(array_shift($elements))             // Pop off first item and switch
{
    case 'Some-text-goes-here':
        ShowPicture($elements); // passes rest of parameters to internal function
        break;
    case 'more':
        ...
    default:
        header('HTTP/1.1 404 Not Found');
        Show404Error();
}

This is how big sites and CMS-systems do it, because it allows far more flexibility in parsing URLs, config and database dependent URLs etc. For sporadic usage the hardcoded rewrite rules in .htaccess will do fine though.

If your host not at pvn or dedicated, it's dificult to restart server.

Better solution from me, just edit your CSS file (at another domain or your subdomain) that call font eot, woff etc to your origin (your-domain or www yourdomain). it will solve your problem.

I mean, edit relative url on css to absolute url origin domain

The best solution I found so far is (it is sort of pseudo-code, the $isLoggedIn is pseudo variable for http auth):

At the time of "logout" just store some info to the session saying that user is actually logged out.

function logout()
{
  //$isLoggedIn = false; //This does not work (point of this question)
  $_SESSION['logout'] = true;
}

In the place where I check for authentication I expand the condition:

function isLoggedIn()
{
  return $isLoggedIn && !$_SESSION['logout'];
}

Session is somewhat linked to the state of http authentication so user stays logged out as long as he keeps the browser open and as long as http authentication persists in the browser.

What to do to correct this is create a file called php.ini and save it in the same location as your .htaccess file and enter the following code instead:

upload_max_filesize = "250M"
post_max_size = "250M"

Try:

php_value error_reporting 2039

if you have long processing server side code, I don't think it does fall into 404 as you said ("it goes to a webpage is not found error page")

Browser should report request timeout error.

You may do 2 things:

Based on CGI/Server side engine increase timeout there

PHP : http://www.php.net/manual/en/info.configuration.php#ini.max-execution-time - default is 30 seconds

In php.ini:

max_execution_time 60

Increase apache timeout - default is 300 (in version 2.4 it is 60).

In your httpd.conf (in server config or vhost config)

TimeOut 600

Note that first setting allows your PHP script to run longer, it will not interferre with network timeout.

Second setting modify maximum amount of time the server will wait for certain events before failing a request

Sorry, I'm not sure if you are using PHP as server side processing, but if you provide more info I will be more accurate.

RewriteRule ^(.*)foobar(.*)$ http://www.example.com/index.php [L,R=301]

(No space inside your website)

Found my solution on Apache/2.2.15 (Unix).

And Thanks for answer from @QuantumHive:

First: I finded all

Order allow,deny
Deny from all

instead of

Order allow,deny

Allow from all

and then:

I setted

#
# Control access to UserDir directories.  The following is an example
# for a site where these directories are restricted to read-only.
#
#<Directory /var/www/html>
#    AllowOverride FileInfo AuthConfig Limit
#    Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec
#    <Limit GET POST OPTIONS>
#        Order allow,deny
#        Allow from all
#    </Limit>
#    <LimitExcept GET POST OPTIONS>
#        Order deny,allow
#        Deny from all
#    </LimitExcept>
#</Directory>

Remove the previous "#" annotation to

#
# Control access to UserDir directories.  The following is an example
# for a site where these directories are restricted to read-only.
#
<Directory /var/www/html>
    AllowOverride FileInfo AuthConfig Limit
    Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec
    <Limit GET POST OPTIONS>
        Order allow,deny
        Allow from all
    </Limit>
    <LimitExcept GET POST OPTIONS>
        Order deny,allow
        Deny from all
    </LimitExcept>
</Directory>

ps. my WebDir is: /var/www/html

ErrorDocument 403 /maintenance.html
Order Allow,Deny
Allow from #:#:#:#:#:#

For me, this seems to work (Using IPv6 rather than IPv4) I don't know if this is different for some websites but for mine this works.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^(.*)/(public)/(index.php)/$ $1/$4 [L]
</IfModule>

Put this code in your .htaccess file

RewriteEngine On
ErrorDocument 404 /404.php

where 404.php is the file name and placed at root. You can put full path over here.

I tried @abimelex solution, but in Slim 3.0, mapping the OPTIONS requests goes like:

$app = new \Slim\App();
$app->options('/books/{id}', function ($request, $response, $args) {
    // Return response headers
});

https://www.slimframework.com/docs/objects/router.html#options-route

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)$">
Header set Cache-Control "max-age=2592000, public"
</filesMatch>
<filesMatch "\.(css)$">
Header set Cache-Control "max-age=604800, public"
</filesMatch>
<filesMatch "\.(js)$">
Header set Cache-Control "max-age=216000, private"
</filesMatch>
<filesMatch "\.(xml|txt)$">
Header set Cache-Control "max-age=216000, public, must-revalidate"
</filesMatch>
<filesMatch "\.(html|htm|php)$">
Header set Cache-Control "max-age=1, private, must-revalidate"
</filesMatch>
</ifModule>
# END Caching

Problem is if you type /public and it will still be available in the url, therefor i created a fix which should be placed in the public/index.php

  $uri = urldecode(
     parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)
  );

  if(stristr($uri, '/public/') == TRUE) {

    if(file_exists(__DIR__.'/public'.$uri)){

    }else{

      $actual_link = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") . "://{$_SERVER['HTTP_HOST']}{$_SERVER['REQUEST_URI']}";
      $actual_link = str_replace('public/', '',$actual_link);
      header("HTTP/1.0 404 Not Found");
      header("Location: ".$actual_link."");
      exit();
      return false;
   }}

this peace of code will remove public from the url and will give a 404 and then redirects to the url without the public

This seemed the simplest solution:

RewriteEngine on
RewriteCond %{REQUEST_URI} ^/$
RewriteRule (.*) http://www.example.com/store [R=301,L]

I was getting redirect loops with some of the other solutions.

I know I am late, but this will help someone.

Check if rewrite engine is enabled.

If not, enable rewrite engine and restart server.

sudo a2enmod rewrite
sudo service apache2 restart

console:

<VirtualHost *:80>
        ...
    <Directory ...>
        AllowOverride All
    </Directory>
</VirtualHost>

sudo a2enmod rewrite
sudo service apache2 restart

this worked like magic for me

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

Use this: http://winginx.com/htaccess

Online converter, nice way and time saver ;)

Below answer is specific to C#, but the concept should be applicable to all the different platforms.

To allow Cross Origin Requests from a web api, You need to allow Option requests to your Application and Add below annotation at controller level.

[EnableCors(UrlString,Header, Method)] Now the origins can be passed only a s string. SO if you want to pass more than one URL in the request pass it as a comma seperated value.

UrlString = "https://a.hello.com,https://b.hello.com"

Sometimes there is problem with php version. We need to change php version from server. Just write down below string in .htaccess file:

AddHandler application/x-httpd-php5 .php

Server version: Apache/2.4.29 (Ubuntu)

After long search on the web and in the official documentation of apache, the only solution that worked for me came from /usr/share/doc/apache2/README.Debian.gz

To enable SSL, type (as user root):

    a2ensite default-ssl
    a2enmod ssl

In the file /etc/apache2/sites-available/000-default.conf add the

Redirect "/" "https://sub.domain.com/"

<VirtualHost *:80>

    #ServerName www.example.com
    DocumentRoot /var/www/owncloud
    Redirect "/" "https://sub.domain.com/"

That's it.

P.S: If you want to read the manual without extracting:

gunzip -cd /usr/share/doc/apache2/README.Debian.gz

I used http://jafty.com/blog/enable-mod_rewrite-on-apache-ec2-linux-server/ to determine that after upgrading to PHP 5.6 (from 4.9.13) it also update the http (Apache) and I needed to edit the /etc/httpd/conf/httpd.conf file, I quote...

Basically, you’ll be adding All insted of None to AllowOverride, you do not want to edit the main directory configuration, you want to edit the one that looks like this:

<Directory “/var/www/html”>

Not:

<Directory />

Then restart Apache with:

sudo service httpd restart

NOTE - in my tiredness I did change a different Directory element and it made no difference, so ensure you do it for /var/www/html

The article also explains how to check mod-rewrite is enabled.

I like this method of redirecting from http to https. Because I don't need to edit it for each site.

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]

This syntax has changed with the newer Apache HTTPd server, please see upgrade to apache 2.4 doc for full details.

2.2 configuration syntax was

Order deny,allow
Deny from all

2.4 configuration now is

Require all denied

Thus, this 2.2 syntax

order deny,allow
deny from all
allow from 127.0.0.1

Would ne now written

Require local

To answer the first question of the three asked, a simple way to see if the .htaccess file is working or not is to trigger a custom error at the top of the .htaccess file:

ErrorDocument 200 "Hello. This is your .htaccess file talking."
RewriteRule ^ - [L,R=200]

On to your second question, if the .htaccess file is not being read it is possible that the server's main Apache configuration has AllowOverride set to None. Apache's documentation has troubleshooting tips for that and other cases that may be preventing the .htaccess from taking effect.

Finally, to answer your third question, if you need to debug specific variables you are referencing in your rewrite rule or are using an expression that you want to evaluate independently of the rule you can do the following:

Output the variable you are referencing to make sure it has the value you are expecting:

ErrorDocument 200 "Request: %{THE_REQUEST} Referrer: %{HTTP_REFERER} Host: %{HTTP_HOST}"
RewriteRule ^ - [L,R=200]

Test the expression independently by putting it in an <If> Directive. This allows you to make sure your expression is written properly or matching when you expect it to:

<If "%{REQUEST_URI} =~ /word$/">
    ErrorDocument 200 "Your expression is priceless!"
    RewriteRule ^ - [L,R=200]
</If>

Happy .htaccess debugging!

The scss solution for Bootstrap 4.0

.modal { max-height: 100vh; .modal-dialog { .modal-content { .modal-body { max-height: calc(80vh - 140px); overflow-y: auto; } } } }

Make sure the .modal max-height is 100vh. Then for .modal-body use calc() function to calculate desired height. In above case we want to occupy 80vh of the viewport, reduced by the size of header + footer in pixels. This is around 140px together but you can measure it easily and apply your own custom values. For smaller/taller modal modify 80vh accordingly.

Finally I got it:

The above shows the default encoding of python is utf8. Then the error is no more.

On mousedown, start set the state, if the mousemove event is fired record it, finally on mouseup, check if the mouse moved. If it moved, we've been dragging. If we've not moved, it's a click.

var isDragging = false;
$("a")
.mousedown(function() {
    isDragging = false;
})
.mousemove(function() {
    isDragging = true;
 })
.mouseup(function() {
    var wasDragging = isDragging;
    isDragging = false;
    if (!wasDragging) {
        $("#throbble").toggle();
    }
});

Here's a demo: http://jsfiddle.net/W7tvD/1399/

For a virtual function you need to provide implementation in the base class. However derived class can override this implementation with its own implementation. Normally , for pure virtual functions implementation is not provided. You can make a function pure virtual with =0 at the end of function declaration. Also, a class containing a pure virtual function is abstract i.e. you can not create a object of this class.

#!/usr/bin/env node --max-old-space-size=4096 in the ionic-app-scripts.js dint work

But after Modifying: the following file it worked

node_modules/.bin/ionic-app-scripts.cmd

By adding:

@IF EXIST "%~dp0\node.exe" ( "%~dp0\node.exe" "%~dp0..@ionic\app-scripts\bin\ionic-app-scripts.js" %* ) ELSE ( @SETLOCAL @SET PATHEXT=%PATHEXT:;.JS;=;% node --max_old_space_size=4096 "%~dp0..@ionic\app-scripts\bin\ionic-app-scripts.js" %* )

If the number is stored in a string (which it would be if typed by a user), you can use atoi() to convert it to an integer.

An integer can be assigned directly to a character. A character is different mostly just because how it is interpreted and used.

char c = atoi("61");

Now there is already no need to use JSON.stringify explicitly. Just execute this line of code

$.cookie.json = true;

After that you can save any object in cookie, which will be automatically converted to JSON and back from JSON when reading cookie.

var user = { name: "name", age: 25 }
$.cookie('user', user);
...

var currentUser = $.cookie('user');
alert('User name is ' + currentUser.name);

But JSON library does not come with jquery.cookie, so you have to download it by yourself and include into html page before jquery.cookie.js

You should install PDO on your server. Edit your php.ini (look at your phpinfo(), "Loaded Configuration File" line, to find the php.ini file path). Find and uncomment the following line (remove the ; character):

;extension=pdo_mysql.so

Then, restart your Apache server. For more information, please read the documentation.

It is really easy to do a bulk insert in Laravel with or without the query builder. You can use the following official approach.

Entity::upsert([
    ['name' => 'Pierre Yem Mback', 'city' => 'Eseka', 'salary' => 10000000],
    ['name' => 'Dial rock 360', 'city' => 'Yaounde', 'salary' => 20000000],
    ['name' => 'Ndibou La Menace', 'city' => 'Dakar', 'salary' => 40000000]
], ['name', 'city'], ['salary']);

Try using Object.setPrototypeOf()

Explanation: Set prototype of arguments to Array.prototype

function toArray() {_x000D_
  return Object.setPrototypeOf(arguments, Array.prototype)_x000D_
} _x000D_
_x000D_
console.log(toArray("abc", 123, {def:456}, [0,[7,[14]]]))

Explanation: Take each index of arguments , place item into an array at corresponding index of array.

could alternatively use Array.prototype.map()

function toArray() {_x000D_
  return [].map.call(arguments, (_,k,a) => a[k])_x000D_
} _x000D_
_x000D_
console.log(toArray("abc", 123, {def:456}, [0,[7,[14]]]))

Explanation: Take each index of arguments , place item into an array at corresponding index of array.

for..of loop

function toArray() {_x000D_
 let arr = []; for (let prop of arguments) arr.push(prop); return arr_x000D_
} _x000D_
_x000D_
console.log(toArray("abc", 123, {def:456}, [0,[7,[14]]]))

or Object.create()

Explanation: Create object, set properties of object to items at each index of arguments; set prototype of created object to Array.prototype

function toArray() {_x000D_
  var obj = {};_x000D_
  for (var prop in arguments) {_x000D_
    obj[prop] = {_x000D_
      value: arguments[prop],_x000D_
      writable: true,_x000D_
      enumerable: true,_x000D_
      configurable: true_x000D_
    }_x000D_
  } _x000D_
  return Object.create(Array.prototype, obj);_x000D_
}_x000D_
_x000D_
console.log(toArray("abc", 123, {def: 456}, [0, [7, [14]]]))

As for your regexp I guess it should be

^\+{0,2}([\-\. ])?(\(?\d{0,3}\))?([\-\. ])?\(?\d{0,3}\)?([\-\. ])?\d{3}([\-\. ])?\d{4}

But in general the presumption is not correct because one might enter something like ++44 20 1234 56789 or +44 (0) 1234 567890 it is better to do something like this

var phone = document.forms["myForm"]["phone"].value;
var phoneNum = phone.replace(/[^\d]/g, '');
if(phoneNum.length > 6 && phoneNum.length < 11) {  return true;  }

this will assure that entered value has 7 to 10 figures nevertheless what the formatting is. But you have to think about max length for number might be more than 10 as in the sample above.

Another real world example using a list

an extract for a template for php.ini

{% if 'cli/php.ini' in item.d %}
max_execution_time = 0
memory_limit = 1024M
{% else %}
max_execution_time = 300
memory_limit = 512M
{% endif %}

This is the var

php_templates:
  - { s: 'php.ini.j2', d: "/etc/php/{{php_version}}/apache2/php.ini" }
  - { s: 'php.ini.j2', d: "/etc/php/{{php_version}}/cli/php.ini" }

Then i deploy with this

- name: push templated files
  template:
    src: "{{item.s}}"
    dest: "{{item.d}}"
    mode: "{{item.m | default(0644) }}"
    owner: "{{item.o | default('root') }}"
    group: "{{item.g | default('root') }}"
    backup: yes
  with_items: "{{php_templates}}"

Main issue is that you first need to set the location of your x and y ticks. Also, it helps to use the more object-oriented interface to matplotlib. Namely, interact with the axes object directly.

import matplotlib.pyplot as plt
import numpy as np
column_labels = list('ABCD')
row_labels = list('WXYZ')
data = np.random.rand(4,4)
fig, ax = plt.subplots()
heatmap = ax.pcolor(data)

# put the major ticks at the middle of each cell, notice "reverse" use of dimension
ax.set_yticks(np.arange(data.shape[0])+0.5, minor=False)
ax.set_xticks(np.arange(data.shape[1])+0.5, minor=False)


ax.set_xticklabels(row_labels, minor=False)
ax.set_yticklabels(column_labels, minor=False)
plt.show()

Hope that helps.

I don't think maven supports this. If you're on Unix, and don't want to leave your current directory, you could use a small shell script, a shell function, or just a sub-shell:

user@host ~/project$ (cd ~/some/location; mvn install)
[ ... mvn build ... ]
user@host ~/project$

As a bash function (which you could add to your ~/.bashrc):

function mvn-there() {
  DIR="$1"
  shift
  (cd $DIR; mvn "$@")     
} 

user@host ~/project$ mvn-there ~/some/location install)
[ ... mvn build ... ]
user@host ~/project$

I realize this doesn't answer the specific question, but may provide you with what you're after. I'm not familiar with the Windows shell, though you should be able to reach a similar solution there as well.

If you're using Visual Studio / MFC, the following solution may make your life easier. It supports both Unicode and MBCS, has comments, doesn't have dependencies other than CString, and works well enough for me. It doesn't support line breaks embedded within a quoted string, but I don't care so long as it doesn't crash in that case, which it doesn't.

The overall strategy is, handle quoted and empty strings as special cases, and use Tokenize for the rest. For quoted strings, the strategy is, find the real closing quote, keeping track of whether pairs of consecutive quotes were encountered. If they were, use Replace to convert the pairs to singles. No doubt there are more efficient methods but performance wasn't sufficiently critical in my case to justify further optimization.

one has not been assigned so points to an unpredictable location. You should either place it on the stack:

Vector one;
one.a = 12;
one.b = 13;
one.c = -11

or dynamically allocate memory for it:

Vector* one = malloc(sizeof(*one))
one->a = 12;
one->b = 13;
one->c = -11
free(one);

Note the use of free in this case. In general, you'll need exactly one call to free for each call made to malloc.

The URL structure you're referring to is called the REST endpoint, as opposed to the Web Site Endpoint.

Note: Since this answer was originally written, S3 has rolled out dualstack support on REST endpoints, using new hostnames, while leaving the existing hostnames in place. This is now integrated into the information provided, below.

If your bucket is really in the us-east-1 region of AWS -- which the S3 documentation formerly referred to as the "US Standard" region, but was subsequently officially renamed to the "U.S. East (N. Virginia) Region" -- then http://s3-us-east-1.amazonaws.com/bucket/ is not the correct form for that endpoint, even though it looks like it should be. The correct format for that region is either http://s3.amazonaws.com/bucket/ or http://s3-external-1.amazonaws.com/bucket/.¹

The format you're using is applicable to all the other S3 regions, but not US Standard US East (N. Virginia) [us-east-1].

S3 now also has dual-stack endpoint hostnames for the REST endpoints, and unlike the original endpoint hostnames, the names of these have a consistent format across regions, for example s3.dualstack.us-east-1.amazonaws.com. These endpoints support both IPv4 and IPv6 connectivity and DNS resolution, but are otherwise functionally equivalent to the existing REST endpoints.

If your permissions and configuration are set up such that the web site endpoint works, then the REST endpoint should work, too.

However... the two endpoints do not offer the same functionality.

Roughly speaking, the REST endpoint is better-suited for machine access and the web site endpoint is better suited for human access, since the web site endpoint offers friendly error messages, index documents, and redirects, while the REST endpoint doesn't. On the other hand, the REST endpoint offers HTTPS and support for signed URLs, while the web site endpoint doesn't.

Choose the correct type of endpoint (REST or web site) for your application:

http://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteEndpoints.html#WebsiteRestEndpointDiff

¹ s3-external-1.amazonaws.com has been referred to as the "Northern Virginia endpoint," in contrast to the "Global endpoint" s3.amazonaws.com. It was unofficially possible to get read-after-write consistency on new objects in this region if the "s3-external-1" hostname was used, because this would send you to a subset of possible physical endpoints that could provide that functionality. This behavior is now officially supported on this endpoint, so this is probably the better choice in many applications. Previously, s3-external-2 had been referred to as the "Pacific Northwest endpoint" for US-Standard, though it is now a CNAME in DNS for s3-external-1 so s3-external-2 appears to have no purpose except backwards-compatibility.

Here is the pure Javascript version of it with LIVE search for ALL COLUMNS :

function search_table(){
  // Declare variables 
  var input, filter, table, tr, td, i;
  input = document.getElementById("search_field_input");
  filter = input.value.toUpperCase();
  table = document.getElementById("table_id");
  tr = table.getElementsByTagName("tr");

  // Loop through all table rows, and hide those who don't match the search query
  for (i = 0; i < tr.length; i++) {
    td = tr[i].getElementsByTagName("td") ; 
    for(j=0 ; j<td.length ; j++)
    {
      let tdata = td[j] ;
      if (tdata) {
        if (tdata.innerHTML.toUpperCase().indexOf(filter) > -1) {
          tr[i].style.display = "";
          break ; 
        } else {
          tr[i].style.display = "none";
        }
      } 
    }
  }
}

What is currentWorksheet? It works if you use the built-in ActiveSheet.

dataStartRow=1
dataStartCol=1
dataEndRow=4
dataEndCol=4
Set currentWorksheet=ActiveSheet
dataTable = currentWorksheet.Range(currentWorksheet.Cells(dataStartRow, dataStartCol), currentWorksheet.Cells(dataEndRow, dataEndCol))

Your question is: are these not modules capable of declaring variables at global scope?

Answer: YES, they are "capable"

The only point is that references to global variables in ThisWorkbook or a Sheet module have to be fully qualified (i.e., referred to as ThisWorkbook.Global1, e.g.) References to global variables in a standard module have to be fully qualified only in case of ambiguity (e.g., if there is more than one standard module defining a variable with name Global1, and you mean to use it in a third module).

For instance, place in Sheet1 code

Public glob_sh1 As String

Sub test_sh1()
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

place in ThisWorkbook code

Public glob_this As String

Sub test_this()
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

and in a Standard Module code

Public glob_mod As String

Sub test_mod()
    glob_mod = "glob_mod"
    ThisWorkbook.glob_this = "glob_this"
    Sheet1.glob_sh1 = "glob_sh1"
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

All three subs work fine.

PS1: This answer is based essentially on info from here. It is much worth reading (from the great Chip Pearson).

PS2: Your line Debug.Print ("Hello") will give you the compile error Invalid outside procedure.

PS3: You could (partly) check your code with Debug -> Compile VBAProject in the VB editor. All compile errors will pop.

PS4: Check also Put Excel-VBA code in module or sheet?.

PS5: You might be not able to declare a global variable in, say, Sheet1, and use it in code from other workbook (reading http://msdn.microsoft.com/en-us/library/office/gg264241%28v=office.15%29.aspx#sectionSection0; I did not test this point, so this issue is yet to be confirmed as such). But you do not mean to do that in your example, anyway.

PS6: There are several cases that lead to ambiguity in case of not fully qualifying global variables. You may tinker a little to find them. They are compile errors.

The Simplest way to do this is

private void deleteAppData() {
         try {
        // clearing app data
        String packageName = getApplicationContext().getPackageName();
        Runtime runtime = Runtime.getRuntime();
        runtime.exec("pm clear "+packageName);

    } catch (Exception e) {
        e.printStackTrace();
    } 
}

This will clear the data and remove your app from memory. It is equivalent to clear data option under Settings --> Application Manager --> Your App --> Clear data.

This will remove the data completely as well as force close the app

When you specify a percentage for max-height on a child, it is a percentage of the parent's actual height, not the parent's max-height, oddly enough. The same applies to max-width.

So, when you don't specify an explicit height on the parent, then there's no base height for the child's max-height to be calculated from, so max-height computes to none, allowing the child to be as tall as possible. The only other constraint acting on the child now is the max-width of its parent, and since the image itself is taller than it is wide, it overflows the container's height downwards, in order to maintain its aspect ratio while still being as large as possible overall.

When you do specify an explicit height for the parent, then the child knows it has to be at most 100% of that explicit height. That allows it to be constrained to the parent's height (while still maintaining its aspect ratio).

One way of doing it is to use the ClientScriptManager:

Page.ClientScript.RegisterStartupScript(
    GetType(), 
    "MyKey", 
    "Myfunction();", 
    true);

Does an implicit conversion occur between Task<> and int?

Nope. This is just part of how async/await works.

Any method declared as async has to have a return type of:

• void (avoid if possible)
• Task (no result beyond notification of completion/failure)
• Task<T> (for a logical result of type T in an async manner)

The compiler does all the appropriate wrapping. The point is that you're asynchronously returning urlContents.Length - you can't make the method just return int, as the actual method will return when it hits the first await expression which hasn't already completed. So instead, it returns a Task<int> which will complete when the async method itself completes.

Note that await does the opposite - it unwraps a Task<T> to a T value, which is how this line works:

string urlContents = await getStringTask;

... but of course it unwraps it asynchronously, whereas just using Result would block until the task had completed. (await can unwrap other types which implement the awaitable pattern, but Task<T> is the one you're likely to use most often.)

This dual wrapping/unwrapping is what allows async to be so composable. For example, I could write another async method which calls yours and doubles the result:

public async Task<int> AccessTheWebAndDoubleAsync()
{
    var task = AccessTheWebAsync();
    int result = await task;
    return result * 2;
}

(Or simply return await AccessTheWebAsync() * 2; of course.)

An alternative to substr is to split the string into a list of single characters and process that:

N <- 2
sapply(strsplit(x, ""), function(x, n) paste(tail(x, n), collapse = ""), N)

If using adb devices on Mac OS X no device is displayed and, of course, you have enabled the USB debugging on your device (see http://developer.android.com/tools/device.html), then try with:

$ android update adb
adb has been updated. You must restart adb with the following commands
    adb kill-server
    adb start-server

Then:

$ adb kill-server
$ adb start-server
* daemon not running. starting it now on port ... *
* daemon started successfully *

And finally:

$ adb devices
List of devices attached 
......  device

Your device should be now in the list.

My solution was to add a space between the $ and the {.

For example:

@Value("${appclient.port:}")

becomes

@Value("$ {appclient.port:}")

The problem is that you are passing a nullable type to a non-nullable type.

You can do any of the following solution:

A. Declare your dt as nullable

DateTime? dt = dateTime;

B. Use Value property of the the DateTime? datetime

DateTime dt = datetime.Value;

C. Cast it

DateTime dt = (DateTime) datetime;

Tremendous thanks to ArturZ for pointing me in the right direction on this. I don't have tmpwatch installed on my system so that isn't the cause of the problem in my case. But the end result is the same: The private /tmp that systemd creates is getting removed. Here's what happens:

1. systemd creates a new process via clone() with the CLONE_NEWNS flag to obtain a private namespace. Or maybe it calls unshare() with CLONE_NEWNS. Same thing.

2. systemd creates a subdirectory in /tmp (e.g. /tmp/systemd-namespace-XRiWad/private) and mounts it on /tmp. Because CLONE_NEWNS was set in #1, this mountpoint is invisible to all other processes.

3. systemd then invokes mysqld in this private namespace.

4. Some specific database operations (e.g. "describe ;") create & remove temporary files, which has the side effect of updating the timestamp on /tmp/systemd-namespace-XRiWad/private. Other database operations execute without using /tmp at all.

5. Eventually 10 days go by where even though the database itself remains active, no operations occur that update the timestamp on /tmp/systemd-namespace-XRiWad/private.

6. /bin/systemd-tmpfiles comes along and removes the "old" /tmp/systemd-namespace-XRiWad/private directory, effectively rendering the private /tmp unusable for mysqld while the public /tmp remains available for everything else on the system.

Restarting mysqld works because this starts everything over again at step #1, with a brand new private /tmp directory. However, the problem eventually comes back again. And again.

The simple solution is to configure /bin/systemd-tmpfiles so that it preserves anything in /tmp with the name /tmp/systemd-namespace-*. I did this by creating /etc/tmpfiles.d/privatetmp.conf with the following contents:

x   /tmp/systemd-namespace-*
x   /tmp/systemd-namespace-*/private

Problem solved.

Not really an answer to your question but I had a requirement to sort a List of maps by its values' properties, this will work in your case too:

List<Map<String, Object>> sortedListOfMaps = someListOfMaps.sorted(Comparator.comparing(map -> ((String) map.get("someKey")))).collect(Collectors.toList()))

Just as an update this can be done by using Toad 9 also.Goto Database>Export>Data Pump Export wizard.At the desitination directory window if you dont find any directory in the dropdown,then you probably have to create a directory object.

CREATE OR REPLACE DIRECTORY data_pmp_dir_test AS '/u01/app/oracle/oradata/pmp_dir_test'; 

See this for an example.

Official documentation way worked for me:

conda remove --name myenv --all

Or just conda env remove --name myenv.

To verify that the environment was removed, in your terminal window or an Anaconda Prompt, run:

conda info --envs

The environments list that displays should not show the removed environment.

You anaconda3 enviroments folder might list an empty folder of deleted environment in your anaconda3 installation folder, like:

/opt/anaconda3/envs

its pretty easy if u just want to redirect to a url without any status codes or anything like that u can simple say

from flask import Flask, redirect

app = Flask(__name__)

@app.route('/')
def redirect_to_link():
    # return redirect method, NOTE: replace google.com with the link u want
    return redirect('https://google.com')

here is the link to the Flask Docs for more explanation

Or just put it on one line, as make likes it:

if [ -a myApp ]; then rm myApp; fi;

Although the original post had other issues (i.e. the missing "-d"), the error message is more generic.

curl: (3) [globbing] nested braces not supported at pos X

This is because curly braces {} and square brackets [] are special globbing characters in curl. To turn this globbing off, use the "-g" option.

As an example, the following Solr facet query will fail without the "-g" to turn off curl globbing: curl -g 'http://localhost:8983/solr/query?json.facet={x:{terms:"myfield"}}'

Here is a function generalizing previous approaches, creating a grid of images in PIL:

from PIL import Image
import numpy as np

def pil_grid(images, max_horiz=np.iinfo(int).max):
    n_images = len(images)
    n_horiz = min(n_images, max_horiz)
    h_sizes, v_sizes = [0] * n_horiz, [0] * (n_images // n_horiz)
    for i, im in enumerate(images):
        h, v = i % n_horiz, i // n_horiz
        h_sizes[h] = max(h_sizes[h], im.size[0])
        v_sizes[v] = max(v_sizes[v], im.size[1])
    h_sizes, v_sizes = np.cumsum([0] + h_sizes), np.cumsum([0] + v_sizes)
    im_grid = Image.new('RGB', (h_sizes[-1], v_sizes[-1]), color='white')
    for i, im in enumerate(images):
        im_grid.paste(im, (h_sizes[i % n_horiz], v_sizes[i // n_horiz]))
    return im_grid

It will shrink each row and columns of the grid to the minimum. You can have only a row by using pil_grid(images), or only a column by using pil_grid(images, 1).

One benefit of using PIL over numpy-array based solutions is that you can deal with images structured differently (like grayscale or palette-based images).

Example outputs

def dummy(w, h):
    "Produces a dummy PIL image of given dimensions"
    from PIL import ImageDraw
    im = Image.new('RGB', (w, h), color=tuple((np.random.rand(3) * 255).astype(np.uint8)))
    draw = ImageDraw.Draw(im)
    points = [(i, j) for i in (0, im.size[0]) for j in (0, im.size[1])]
    for i in range(len(points) - 1):
        for j in range(i+1, len(points)):
            draw.line(points[i] + points[j], fill='black', width=2)
    return im

dummy_images = [dummy(20 + np.random.randint(30), 20 + np.random.randint(30)) for _ in range(10)]

pil_grid(dummy_images):

pil_grid(dummy_images, 3):

pil_grid(dummy_images, 1):

Though there are so many good answers, here is my two cents for the future me :P and for anyone who wants it quick and easy.

For Mac:

• connect the device using USB first and make sure debugging is working. Disconnect any other devices and quit emulators.

• open terminal and run the following script

  adb tcpip 5555
  adb connect $(adb shell ifconfig | grep "inet " | grep -v 127.0.0.1 | awk '{print $2}' | cut -d: -f2):5555
  

• disconnect USB connection and the device should be available for WiFi debugging

Explanation:

adb tcpip 5555 commands the device to start listening for connections on port 5555

adb connect $(_ip_address_fetched_):5555 tells to connect on port 5555 of the _ip_address_fetched_ address

where _ip_address_fetched_ includes following:

adb shell ifconfig getting internet configurations using adb shell

grep "inter " filter any line that starts with inter

grep -v 127.0.0.1 exclude localhost.

At this point, output should be like:

inet addr:###.###.#.### Bcast:###.###.#.### Mask:255.255.255.0

awk '{print $2}' get the second part of the components array, separated by space (I'm using zsh).

The output up to this point is

addr:###.###.#.###

cut -d: -f2 split the string by delimiter : and take second part. It will only take your device IP address

Example of calculating time:

work-start   work-stop   lunchbreak    effective time

  07:30:00    17:00:00          1.5                 8  [=((A2-A1)*24)-A3]

If you subtract one time value from another the result you get will represent the fraction of 24 hours, so if you multiply the result with 24 you get the value represented in hours.

In other words: the operation is mutiply, but the meaning is to change the format of the number (from days to hours).

Correct syntax looks like this. See MSDN.

SELECT *
  FROM [FAEB].[dbo].[ExportaComisiones] AS f
  JOIN [zCredifiel].[dbo].[optPerson] AS p

  ON p.vTreasuryId COLLATE Latin1_General_CI_AS = f.RFC COLLATE Latin1_General_CI_AS 

Maybe there is an issue with your composer file. You could try:

• composer install installs the vendor packages according to composer.lock (or creates composer.lock if not present),

• composer update always regenerates composer.lock and installs the lastest versions of available packages based on composer.json

• composer dump-autoload won’t download a thing. It just regenerates the list of all classes that need to be included in the project (autoload_classmap.php). Ideal for when you have a new class inside your project. Ideally, you execute composer dump-autoload -o , for a faster load of your webpages. The only reason it is not default, is because it takes a bit longer to generate (but is only slightly noticeable)

source

Maybe try this

Select cust.*

From dbo.Customers cust
Left Join dbo.Subscribers subs on cust.Customer_ID = subs.Customer_ID
Where subs.Customer_Id Is Null

try this,

$("document").ready(function(){

$("your id here").trigger("click");
});

Add

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

Assuming you want a grayscale image:

im = Image.new('L', (width, height))
im.putdata(an_array.flatten().tolist())
im.save("image.tiff")

I know you tagged your question with 'javascript' but here's a solution that do not depends on javascript at all:

It's a webapp pattern named PRG, and here's a good article that describes it

IEnumerable<int> ids = list.Select(x=>x.ID).Distinct();

Run msbuild Foo.sln /t:Rebuild /v:diag (from C:\Program Files (x86)\MSBuild\12.0\bin) to build your solution from command line and get a bit more details, then find the .csproj. that logs the warning and check its references and references of other projects that use the same common assembly that differs in version.

Edit: You can also set the build verbosity directly in VS2013. Go to Tools > Options menu then go to Projects and Solutions and set MSBuild verbosity to Diagnostic.

Edit: Few clarifications as I just got one myself. In my case warning was due to me adding a reference using Resharper prompt as opposed to the Add Reference dialog, which did it versionless even though both v4 and v12 are available to choose from.

<Reference Include="Microsoft.Build, Version=12.0.0.0, ..." />
<Reference Include="Microsoft.Build.Framework" />

vs

<Reference Include="Microsoft.Build, Version=12.0.0.0, ..." />
<Reference Include="Microsoft.Build.Framework, Version=12.0.0.0, ..." />

In the MSBuild log with /v:diag verbosity it looked like the following. giving details which two references conflicted:-

  There was a conflict between 
  "Microsoft.Build.Framework, Version=4.0.0.0, ..." and

The best way to stay on the same page is to post to the same page:

I cannot create a file with the name+period+extnesion in WS 2012 Explorer longer than 224 characters. Don't shoot the messenger!

In the CMD of the same server I cannot create a longer than 235 character name:

The system cannot find the path specified.

The file with a 224 character name created in the Explorer cannot be opened in Notepad++ - it just comes up with a new file instead.

Check the project properties. It's configurable there if you are using another .net windows application for example

According to the Python os module documentation os.popen has been deprecated since Python 2.6.

I think the solution for modern Python is to use check_output() from the subprocess module.

From the subprocess Python documentation:

subprocess.check_output(args, *, stdin=None, stderr=None, shell=False, universal_newlines=False) Run command with arguments and return its output as a byte string.

If the return code was non-zero it raises a CalledProcessError. The CalledProcessError object will have the return code in the returncode attribute and any output in the output attribute.

If you run through the following code in Python 2.7 (or later):

import subprocess

try:
    print subprocess.check_output(["ping", "-n", "2", "-w", "2", "1.1.1.1"])
except subprocess.CalledProcessError, e:
    print "Ping stdout output:\n", e.output

You should see an output that looks something like this:

Ping stdout output:

Pinging 1.1.1.1 with 32 bytes of data:
Request timed out.
Request timed out.

Ping statistics for 1.1.1.1:
Packets: Sent = 2, Received = 0, Lost = 2 (100% loss),

The e.output string can be parsed to suit the OPs needs.

If you want the returncode or other attributes, they are in CalledProccessError as can be seen by stepping through with pdb

(Pdb)!dir(e)   

['__class__', '__delattr__', '__dict__', '__doc__', '__format__',
 '__getattribute__', '__getitem__', '__getslice__', '__hash__', '__init__',
 '__module__', '__new__', '__reduce__', '__reduce_ex__', '__repr__',
 '__setattr__', '__setstate__', '__sizeof__', '__str__', '__subclasshook__', 
 '__unicode__', '__weakref__', 'args', 'cmd', 'message', 'output', 'returncode']

sed 's/^.\{,5\}//' file.dat worked like a charm for me

int count = Regex.Matches(myString,"$").Count;

Just add the second .absolute div before the other .second div:

<div class="absolute" style="top: 54px"></div>
<div class="absolute">
    <div id="relative"></div>
</div>

Because the two elements have an index 0.

Since 0.11 hive has a NVL function nvl(T value, T default_value)

which says Returns default value if value is null else returns value

SQLite supports a limited subset of ALTER TABLE. The ALTER TABLE command in SQLite allows the user to rename a table or to add a new column to an existing table. It is not possible to rename a column, remove a column, or add or remove constraints from a table. But you can alter table column datatype or other property by the following steps.

1. BEGIN TRANSACTION;
2. CREATE TEMPORARY TABLE t1_backup(a,b);
3. INSERT INTO t1_backup SELECT a,b FROM t1;
4. DROP TABLE t1;
5. CREATE TABLE t1(a,b);
6. INSERT INTO t1 SELECT a,b FROM t1_backup;
7. DROP TABLE t1_backup;
8. COMMIT

For more detail you can refer the link.

For simplicity, you can use a Runnable:

private void runCallback(Runnable callback)
{
    // Run callback
    callback.run();
}

Usage:

runCallback(new Runnable()
{
    @Override
    public void run()
    {
        // Running callback
    }
});

(a) wwww.somewebsite.com/a.txt isn't a 'file URL'. It isn't a URL at all. If you put http:// on the front of it it would be an HTTP URL, which is clearly what you intend here.

(b) FileInputStream is for files, not URLs.

(c) The way to get an input stream from any URL is via URL.openStream(), or URL.getConnection().getInputStream(), which is equivalent but you might have other reasons to get the URLConnection and play with it first.

You need to fix the source of the string in the first place.

A string in .NET is actually just an array of 16-bit unicode code-points, characters, so a string isn't in any particular encoding.

It's when you take that string and convert it to a set of bytes that encoding comes into play.

In any case, the way you did it, encoded a string to a byte array with one character set, and then decoding it with another, will not work, as you see.

Can you tell us more about where that original string comes from, and why you think it has been encoded wrong?

You normally forward the request to a JSP for display. JSP is a view technology which provides a template to write plain vanilla HTML/CSS/JS in and provides ability to interact with backend Java code/variables with help of taglibs and EL. You can control the page flow with taglibs like JSTL. You can set any backend data as an attribute in any of the request, session or application scope and use EL (the ${} things) in JSP to access/display them. You can put JSP files in /WEB-INF folder to prevent users from directly accessing them without invoking the preprocessing servlet.

Kickoff example:

@WebServlet("/hello")
public class HelloWorldServlet extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String message = "Hello World";
        request.setAttribute("message", message); // This will be available as ${message}
        request.getRequestDispatcher("/WEB-INF/hello.jsp").forward(request, response);
    }

}

And /WEB-INF/hello.jsp look like:

<!DOCTYPE html>
<html lang="en">
    <head>
        <title>SO question 2370960</title>
    </head>
    <body>
         <p>Message: ${message}</p>
    </body>
</html>

When opening http://localhost:8080/contextpath/hello this will show

Message: Hello World

in the browser.

I ran across a site a few weeks back. This is a working example of the first column locked but it is not browser compatible with Firefox. I didn't do a lot of checking around but it seems it only works in IE. There are some notes the author provided along with it that you can read.

Lock the First column: http://home.tampabay.rr.com/bmerkey/examples/locked-column-csv.html

Let me know if you need the Javascript to lock the Table headers too.

You can't. It's immediate mode graphics. But you can sort of simulate it by drawing a rectangle over it in the background color with an opacity.

If the image is over something other than a constant color, then it gets quite a bit trickier. You should be able to use the pixel manipulation methods in this case. Just save the area before drawing the image, and then blend that back on top with an opacity afterwards.

  static User _instance;
  
  static User getInstance({name, age}) {
     if(_instance == null) {
       _instance = User(name: name, age: age);
       return _instance;
     }
    return _instance;
  }
}

  print(User.getInstance(name: "baidu", age: 24).age); //24
  
  print(User.getInstance(name: "baidu 2").name); // is not changed //baidu

  print(User.getInstance()); // {name: "baidu": age 24}

Your compiler just tried to compile the file named foo.cc. Upon hitting line number line, the compiler finds:

#include "bar"

or

#include <bar>

The compiler then tries to find that file. For this, it uses a set of directories to look into, but within this set, there is no file bar. For an explanation of the difference between the versions of the include statement look here.

How to tell the compiler where to find it

g++ has an option -I. It lets you add include search paths to the command line. Imagine that your file bar is in a folder named frobnicate, relative to foo.cc (assume you are compiling from the directory where foo.cc is located):

g++ -Ifrobnicate foo.cc

You can add more include-paths; each you give is relative to the current directory. Microsoft's compiler has a correlating option /I that works in the same way, or in Visual Studio, the folders can be set in the Property Pages of the Project, under Configuration Properties->C/C++->General->Additional Include Directories.

Now imagine you have multiple version of bar in different folders, given:

// A/bar
#include<string>
std::string which() { return "A/bar"; }

// B/bar
#include<string>
std::string which() { return "B/bar"; }

// C/bar
#include<string>
std::string which() { return "C/bar"; }

// foo.cc
#include "bar"
#include <iostream>

int main () {
    std::cout << which() << std::endl;
}

The priority with #include "bar" is leftmost:

$ g++ -IA -IB -IC foo.cc
$ ./a.out
A/bar

As you see, when the compiler started looking through A/, B/ and C/, it stopped at the first or leftmost hit.

This is true of both forms, include <> and incude "".

Difference between #include <bar> and #include "bar"

Usually, the #include <xxx> makes it look into system folders first, the #include "xxx" makes it look into the current or custom folders first.

E.g.:

Imagine you have the following files in your project folder:

list
main.cc

with main.cc:

#include "list"
....

For this, your compiler will #include the file list in your project folder, because it currently compiles main.cc and there is that file list in the current folder.

But with main.cc:

#include <list>
....

and then g++ main.cc, your compiler will look into the system folders first, and because <list> is a standard header, it will #include the file named list that comes with your C++ platform as part of the standard library.

This is all a bit simplified, but should give you the basic idea.

Details on <>/""-priorities and -I

According to the gcc-documentation, the priority for include <> is, on a "normal Unix system", as follows:

 /usr/local/include
 libdir/gcc/target/version/include
 /usr/target/include
 /usr/include

For C++ programs, it will also look in /usr/include/c++/version, first. In the above, target is the canonical name of the system GCC was configured to compile code for; [...].

The documentation also states:

You can add to this list with the -Idir command line option. All the directories named by -I are searched, in left-to-right order, before the default directories. The only exception is when dir is already searched by default. In this case, the option is ignored and the search order for system directories remains unchanged.

To continue our #include<list> / #include"list" example (same code):

g++ -I. main.cc

and

#include<list>
int main () { std::list<int> l; }

and indeed, the -I. prioritizes the folder . over the system includes and we get a compiler error.

make a file classAusiliaria.h and in there provide your method signatures.

Now instead of including the .c file include this .h file.

If someone else needs a guaranteed way of STRICTLY sequential way of resolving Promises when performing CRUD operations you also can use the following code as a basis.

As long as you add 'return' before calling each function, describing a Promise, and use this example as a basis the next .then() function call will CONSISTENTLY start after the completion of the previous one:

getRidOfOlderShoutsPromise = () => {
    return readShoutsPromise('BEFORE')
    .then(() => {
        return deleteOlderShoutsPromise();
    })
    .then(() => {
        return readShoutsPromise('AFTER')
    })
    .catch(err => console.log(err.message));
}

deleteOlderShoutsPromise = () => {
    return new Promise ( (resolve, reject) => {
        console.log("in deleteOlderShouts");
        let d = new Date();
        let TwoMinuteAgo = d - 1000 * 90 ;
        All_Shouts.deleteMany({ dateTime: {$lt: TwoMinuteAgo}}, function(err) {
            if (err) reject();
            console.log("DELETED OLDs at "+d);
            resolve();        
        });
    });
}

readShoutsPromise = (tex) => {
    return new Promise( (resolve, reject) => {
        console.log("in readShoutsPromise -"+tex);
        All_Shouts
        .find({})
        .sort([['dateTime', 'ascending']])
        .exec(function (err, data){
            if (err) reject();
            let d = new Date();
            console.log("shouts "+tex+" delete PROMISE = "+data.length +"; date ="+d);
            resolve(data);
        });    
    });
}

If you are using express you need to allow serving of static content by adding something like: var server = express(); server.use(express.static('./public')); // where public is the app root folder, with the fonts contained therein, at any level, i.e. public/fonts or public/dist/fonts... // If you are using connect, google for a similar configuration.

From the comments to the original question, it seems that you have multiple versions of python installed and that pip just goes to the wrong version.

First, to know which version of python you're using, just type which python. You should either see:

which python
/Library/Frameworks/Python.framework/Versions/2.7/bin/python

if you're going to the right version of python, or:

which python
/usr/bin/python

If you're going to the 'wrong' version. To make pip go to the right version, you first have to change the path:

 export PATH=/Library/Frameworks/Python.framework/Versions/2.7/bin/python:${PATH}

typing 'which python' would now get you to the right result. Next, install pip (if it's not already installed for this installation of python). Finally, use it. you should be fine now.

You can use jquery for create element on the fly

$('#form').append('<input type="hidden" name="fieldname" value="fieldvalue" />');

or other way

$('<input>').attr({
    type: 'hidden',
    id: 'fieldId',
    name: 'fieldname'
}).appendTo('form')

UTC dates don't need any timezone info since they're UTC, which by definition means that they have no offset.

Here is a Swift way to get screen sizes, this also takes current interface orientation into account:

var screenWidth: CGFloat {
    if UIInterfaceOrientationIsPortrait(screenOrientation) {
        return UIScreen.mainScreen().bounds.size.width
    } else {
        return UIScreen.mainScreen().bounds.size.height
    }
}
var screenHeight: CGFloat {
    if UIInterfaceOrientationIsPortrait(screenOrientation) {
        return UIScreen.mainScreen().bounds.size.height
    } else {
        return UIScreen.mainScreen().bounds.size.width
    }
}
var screenOrientation: UIInterfaceOrientation {
    return UIApplication.sharedApplication().statusBarOrientation
}

These are included as a standard function in:

To complete Wiktor Stribizew and Dougui answers I would say that /regex/.match?("string") about as fast as "string".match?(/regex/).

Note: times varies, sometimes /regex/.match?("string") is faster and sometimes "string".match?(/regex/), the differences maybe only due to the machine activity.

You just use an ImageButton and make the background whatever you want and set the icon as the src.

<ImageButton
    android:id="@+id/ImageButton01"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/album_icon"
    android:background="@drawable/round_button" />

This is your homework, so I assume you NEED to use the loops and switch statments. That's O.K, but why are all your loops inner to the privious ones ?

Just take them out to the same "level" and your code is just fine! (part to the low/up mixup).

A tip: Pressing extra 'Enter' & 'Space' is free! (That's the first thing I did to your code, and the problem became very trivial)

I just made an imageCrop and Upload feature with

https://www.npmjs.com/package/react-image-crop

to get the ImagePreview ( the cropped image rendering in a canvas)

https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/toBlob

canvas.toBlob(function(blob){...}, 'image/jpeg', 0.95);

I prefer sending data in blob with content type image/jpeg rather than toDataURL ( a huge base64 string`

My implementation for uploading to Azure Blob using SAS URL

axios.post(azure_sas_url, image_in_blob, {
   headers: {
      'x-ms-blob-type': 'BlockBlob',
      'Content-Type': 'image/jpeg'
   }
})

Quickest, easiest laziest way to solve the problem:

1. Right-click on the project icon in Solution Explorer and choose "Properties".
2. Go to the "Application" tab and choose an earlier .NET target framework.
3. Save changes.
4. Go to the "Application" tab and choose the initial .NET target framework.
5. Save changes => problem solved!

I encountered the same problem in child components where initially it would have to have the current value of the Subject, then subscribe to the Subject to listen to changes. I just maintain the current value in the Service so it is available for components to access, e.g. :

import {Storage} from './storage';
import {Injectable} from 'angular2/core';
import {Subject}    from 'rxjs/Subject';

@Injectable()
export class SessionStorage extends Storage {

  isLoggedIn: boolean;

  private _isLoggedInSource = new Subject<boolean>();
  isLoggedIn = this._isLoggedInSource.asObservable();
  constructor() {
    super('session');
    this.currIsLoggedIn = false;
  }
  setIsLoggedIn(value: boolean) {
    this.setItem('_isLoggedIn', value, () => {
      this._isLoggedInSource.next(value);
    });
    this.isLoggedIn = value;
  }
}

A component that needs the current value could just then access it from the service, i.e,:

sessionStorage.isLoggedIn

Not sure if this is the right practice :)

That's the way the DataReader works, it's designed to read the database rows one at a time.

while(reader.Read()) 
{
  var value1 = reader.GetValue(0); // On first iteration will be hello
  var value2 = reader.GetValue(1); // On first iteration will be hello2
  var value3 = reader.GetValue(2); // On first iteration will be hello3
}

You could add this little snippet of code to add a nice "…" to the ending of the line if the content is to large to fit on one line:

li {
  overflow: hidden; 
  text-overflow: ellipsis;
  white-space: nowrap;
}

Format in other syntax is possible in this way

[DateTime]::Today.AddDays(-1).ToString("yyyyMMdd")

In C/C++ you have header files (*.H). There you declare your functions/classes. So for example you will have to #include "second.h" to your main.cpp file.

In second.h you just declare like this void yourFunction(); In second.cpp you implement it like

void yourFunction() { 
   doSomethng(); 
}

Don't forget to #include "second.h" also in the beginning of second.cpp

Hope this helps:)

I am guessing you're confused with the parameterization of the types:

// This works, because there is one class/type definition in the parameterized <> field
ArrayList<String> myArrayList = new ArrayList<String>(); 


// This doesn't work, as you cannot use primitive types here
ArrayList<char> myArrayList = new ArrayList<char>();

I love empty if-else and while(0) operators.

For example:

#define CMD1(X) do { foo(x); bar(x); } while (0)
#define CMD2(X) if (1) { foo(x); bar(x); } else

it will automatically create a .gitignore file if not then create a file name .gitignore and add copy & paste the below code

# dependencies
/node_modules
/.pnp
.pnp.js

# testing
/coverage

# production
/build

# misc
.DS_Store
.env.local
.env.development.local
.env.test.local
.env.production.local

npm-debug.log*
yarn-debug.log*
yarn-error.log*

these below are all unnecessary files

See https://help.github.com/articles/ignoring-files/ for more about ignoring files.

and save the .gitignore file and you can upload

For latest mac os, Below shortcuts works for me.

Jump to beginning of the line == shift + fn + RightArrow

Jump to ending of the line == shift + fn + LeftArrow

Just use

<input type="number" id="foo" runat="server" />

It'll work on all modern browsers except IE +10. Here is a full list:

http://caniuse.com/#feat=input-number

for (int i = 0; i < 5; i++){
    int asciiVal = rand()%26 + 97;
    char asciiChar = asciiVal;
    cout << asciiChar << " and ";
}

You may be looking for auto-fill:

grid-template-columns: repeat(auto-fill, 186px);

Demo: http://codepen.io/alanbuchanan/pen/wJRMox

To use up the available space more efficiently, you could use minmax, and pass in auto as the second argument:

grid-template-columns: repeat(auto-fill, minmax(186px, auto));

Demo: http://codepen.io/alanbuchanan/pen/jBXWLR

If you don't want the empty columns, you could use auto-fit instead of auto-fill.

just create new android project and copy paste my code and have fun! :) also remember in xml i have image view and his background images replace with yout own images thanks..

I think this comes closest to what you wish:

(From IntelliJ IDEA Q&A for Eclipse Users):

The above can be combined with a recently introduced option in Compiler settings to get a view very similar to that of Eclipse.

Things to do:

1. Switch to 'Problems' view in the Project pane:
   
   

2. Enable the setting to compile the project automatically :
   
   

3. Finally, look at the Problems view:
   
   

Here is a comparison of what the same project (with a compilation error) looks like in Intellij IDEA 13.xx and Eclipse Kepler:

Relevant Links: The maven project shown above : https://github.com/ajorpheus/CompileTimeErrors
FAQ For 'Eclipse Mode' / 'Automatically Compile' a project : http://devnet.jetbrains.com/docs/DOC-1122

As far as I know, QPixmap is used for displaying images and QImage for reading them. There are QPixmap::convertFromImage() and QPixmap::fromImage() functions to convert from QImage.

If you're using C# 7.1 or later, go with the nawfal's answer and just change the return type of your Main method to Task or Task<int>. If you are not:

• Have an async Task MainAsync like Johan said.
• Call its .GetAwaiter().GetResult() to catch the underlying exception like do0g said.
• Support cancellation like Cory said.
• A second CTRL+C should terminate the process immediately. (Thanks binki!)
• Handle OperationCancelledException - return an appropriate error code.

The final code looks like:

private static int Main(string[] args)
{
    var cts = new CancellationTokenSource();
    Console.CancelKeyPress += (s, e) =>
    {
        e.Cancel = !cts.IsCancellationRequested;
        cts.Cancel();
    };

    try
    {
        return MainAsync(args, cts.Token).GetAwaiter().GetResult();
    }
    catch (OperationCanceledException)
    {
        return 1223; // Cancelled.
    }
}

private static async Task<int> MainAsync(string[] args, CancellationToken cancellationToken)
{
    // Your code...

    return await Task.FromResult(0); // Success.
}

No, you don't need to add them as a remote. That would be clumbersome and a pain to do each time.

Grabbing their commits:

git fetch [email protected]:theirusername/reponame.git theirbranch:ournameforbranch

This creates a local branch named ournameforbranch which is exactly the same as what theirbranch was for them. For the question example, the last argument would be foo:foo.

Note :ournameforbranch part can be further left off if thinking up a name that doesn't conflict with one of your own branches is bothersome. In that case, a reference called FETCH_HEAD is available. You can git log FETCH_HEAD to see their commits then do things like cherry-picked to cherry pick their commits.

Pushing it back to them:

Oftentimes, you want to fix something of theirs and push it right back. That's possible too:

git fetch [email protected]:theirusername/reponame.git theirbranch
git checkout FETCH_HEAD

# fix fix fix

git push [email protected]:theirusername/reponame.git HEAD:theirbranch

If working in detached state worries you, by all means create a branch using :ournameforbranch and replace FETCH_HEAD and HEAD above with ournameforbranch.

I might just have just gotten a way to bust the frame buster buster javascript. Using the getElementsByName in my javascript function, i've set a loop between the frame buster and the actual frame buster buster script. check this post out. http://www.phcityonweb.com/frame-buster-buster-buster-2426

Try to put stateHidden on as your activity windowSoftInputMode value

http://developer.android.com/reference/android/R.attr.html#windowSoftInputMode

For example for your Activity:

this.getWindow().setSoftInputMode(
    WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

I have struggled with this for a long time, until I came across the cppreference.com explanation of the value categories.

It is actually rather simple, but I find that it is often explained in a way that's hard to memorize. Here it is explained very schematically. I'll quote some parts of the page:

Primary categories

The primary value categories correspond to two properties of expressions:

• has identity: it's possible to determine whether the expression refers to the same entity as another expression, such as by comparing addresses of the objects or the functions they identify (obtained directly or indirectly);

• can be moved from: move constructor, move assignment operator, or another function overload that implements move semantics can bind to the expression.

Expressions that:

• have identity and cannot be moved from are called lvalue expressions;
• have identity and can be moved from are called xvalue expressions;
• do not have identity and can be moved from are called prvalue expressions;
• do not have identity and cannot be moved from are not used.

lvalue

An lvalue ("left value") expression is an expression that has identity and cannot be moved from.

rvalue (until C++11), prvalue (since C++11)

A prvalue ("pure rvalue") expression is an expression that does not have identity and can be moved from.

xvalue

An xvalue ("expiring value") expression is an expression that has identity and can be moved from.

glvalue

A glvalue ("generalized lvalue") expression is an expression that is either an lvalue or an xvalue. It has identity. It may or may not be moved from.

rvalue (since C++11)

An rvalue ("right value") expression is an expression that is either a prvalue or an xvalue. It can be moved from. It may or may not have identity.

I have used this one on MySQL, MS Access and SQL Server. The id fields are the fields on wich the tables coincide, not necesarily the primary index.

UPDATE DestTable INNER JOIN SourceTable ON DestTable.idField = SourceTable.idField SET DestTable.Field1 = SourceTable.Field1, DestTable.Field2 = SourceTable.Field2...

You can use exec for that:

>>> foo = "bar"
>>> exec(foo + " = 'something else'")
>>> print bar
something else
>>> 

This seems to occur when .git/HEAD refers to a branch which does not exist. I ran into this error in a repo that had nothing in .git/refs/heads. I have no idea how the repo got into that state, I inherited from someone that left the company.

Below are few basic differences between require and include:

Require:

1. Require reads the file from the file system, parses it, saves to the memory and runs it in a given place which means if you will even change anything while the script is running than that change will not reflect.
2. We require file by name, not by module name.
3. It is typically used for libraries and extensions.

Include:

1. When you include a module into your class it behaves as if you took the code defined in your module and inserted it in your class.
2. We include module name, not the file name.
3. It is typically used to dry up the code and to remove duplication in the code.

This is how I implemeted Activity->Service Communication: on my Activity i had

private static class MyResultReciever extends ResultReceiver {
     /**
     * Create a new ResultReceive to receive results.  Your
     * {@link #onReceiveResult} method will be called from the thread running
     * <var>handler</var> if given, or from an arbitrary thread if null.
     *

     */
     public MyResultReciever(Handler handler) {
         super(handler);
     }

     @Override
     protected void onReceiveResult(int resultCode, Bundle resultData) {
         if (resultCode == 100) {
             //dostuff
         }
     }

And then I used this to start my Service

protected void onCreate(Bundle savedInstanceState) {
MyResultReciever resultReciever = new MyResultReciever(handler);
        service = new Intent(this, MyService.class);
        service.putExtra("receiver", resultReciever);
        startService(service);
}

In my Service i had

public int onStartCommand(Intent intent, int flags, int startId) {
    if (intent != null)
        resultReceiver = intent.getParcelableExtra("receiver");
    return Service.START_STICKY;
}

Hope this Helps

There are two different ways of importing components in react and the recommended way is component way

1. Library way(not recommended)
2. Component way(recommended)

PFB detail explanation

Library way of importing

import { Button } from 'react-bootstrap';
import { FlatButton } from 'material-ui';

This is nice and handy but it does not only bundles Button and FlatButton (and their dependencies) but the whole libraries.

Component way of importing

One way to alleviate it is to try to only import or require what is needed, lets say the component way. Using the same example:

import Button from 'react-bootstrap/lib/Button';
import FlatButton from 'material-ui/lib/flat-button';

This will only bundle Button, FlatButton and their respective dependencies. But not the whole library. So I would try to get rid of all your library imports and use the component way instead.

If you are not using lot of components then it should reduce considerably the size of your bundled file.

The complete article that works for me: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Base64_encoding_and_decoding

The part where we encode from Unicode/UTF-8 is

function utf8_to_b64( str ) {
   return window.btoa(unescape(encodeURIComponent( str )));
}

function b64_to_utf8( str ) {
   return decodeURIComponent(escape(window.atob( str )));
}

// Usage:
utf8_to_b64('? à la mode'); // "4pyTIMOgIGxhIG1vZGU="
b64_to_utf8('4pyTIMOgIGxhIG1vZGU='); // "? à la mode"

This is one of the most used methods nowadays.

The fundamental issue with your code is that you mix two APIs. Unfortunately online resources are not great at pointing this out, but there are two semaphore APIs on UNIX-like systems:

• POSIX IPC API, which is a standard API
• System V API, which is coming from the old Unix world, but practically available almost all Unix systems

Looking at the code above you used semget() from the System V API and tried to post through sem_post() which comes from the POSIX API. It is not possible to mix them.

To decide which semaphore API you want you don't have so many great resources. The simple best is the "Unix Network Programming" by Stevens. The section that you probably interested in is in Vol #2.

These two APIs are surprisingly different. Both support the textbook style semaphores but there are a few good and bad points in the System V API worth mentioning:

• it builds on semaphore sets, so once you created an object with semget() that is a set of semaphores rather then a single one
• the System V API allows you to do atomic operations on these sets. so you can modify or wait for multiple semaphores in a set
• the SysV API allows you to wait for a semaphore to reach a threshold rather than only being non-zero. waiting for a non-zero threshold is also supported, but my previous sentence implies that
• the semaphore resources are pretty limited on every unixes. you can check these with the 'ipcs' command
• there is an undo feature of the System V semaphores, so you can make sure that abnormal program termination doesn't leave your semaphores in an undesired state

After data-binding, do this:

ddlColor.Items.Insert(0, new ListItem("Select","NA")); //updated code

Or follow Brian's second suggestion if you want to do it in markup.

You should probably add a RequiredFieldValidator control and set its InitialValue to "NA".

<asp:RequiredFieldValidator .. ControlToValidate="ddlColor" InitialValue="NA" />

I needed to do many very simple XML requests and after reading @Ivan Krechetov's comment about the speed hit of SOAP, I tried his code and discovered http_post_data() is not built into PHP 5.2. Not really wanting to install it, I tried cURL which is on all my servers. Although I do not know how fast cURL is compared to SOAP, it sure was easy to do what I needed. Below is a sample with cURL for anyone needing it.

$xml_data = '<?xml version="1.0" encoding="UTF-8" ?>
<priceRequest><customerNo>123</customerNo><password>abc</password><skuList><SKU>99999</SKU><lineNumber>1</lineNumber></skuList></priceRequest>';
$URL = "https://test.testserver.com/PriceAvailability";

$ch = curl_init($URL);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "$xml_data");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);


print_r($output);

You can execute below code

SELECT Time FROM [TableName] where DATEPART(YYYY,[Time])='2018' and DATEPART(MM,[Time])='06' and DATEPART(DD,[Time])='14

$(selector).filter(function(){return this.value==yourval}).remove();

In Python 2 you can define your own generator function like this:

def accumu(lis):
    total = 0
    for x in lis:
        total += x
        yield total

In [4]: list(accumu([4,6,12]))
Out[4]: [4, 10, 22]

And in Python 3.2+ you can use itertools.accumulate():

In [1]: lis = [4,6,12]

In [2]: from itertools import accumulate

In [3]: list(accumulate(lis))
Out[3]: [4, 10, 22]

I had two manifest.xml file in my app section,so I needed to change package name in both

The way you're writing your print statement is unnecessarily verbose. There's no need to separate the newline into its own string. This is sufficient.

print "hello.\n";

This realization will probably make your coding easier in general.

In addition to using use feature "say" or use 5.10.0 or use Modern::Perl to get the built in say feature, I'm going to pimp perl5i which turns on a lot of sensible missing Perl 5 features by default.

I think pip, pip2 and pip3 are not soft links to the same executable file path. Note these commands and results in my Linux terminal:

mrz@mrz-pc ~ $ ls -l `which pip`
-rwxr-xr-x 1 root root 292 Nov 10  2016 /usr/bin/pip
mrz@mrz-pc ~ $ ls -l `which pip2`
-rwxr-xr-x 1 root root 283 Nov 10  2016 /usr/bin/pip2
mrz@mrz-pc ~ $ ls -l `which pip3`
-rwxr-xr-x 1 root root 293 Nov 10  2016 /usr/bin/pip3
mrz@mrz-pc ~ $ pip -V
pip 9.0.1 from /home/mrz/.local/lib/python2.7/site-packages (python 2.7)
mrz@mrz-pc ~ $ pip2 -V
pip 8.1.1 from /usr/lib/python2.7/dist-packages (python 2.7)
mrz@mrz-pc ~ $ pip3 -V
pip 9.0.1 from /home/mrz/.local/lib/python3.5/site-packages (python 3.5)

As you see they exist in different paths.

pip3 always operates on the Python3 environment only, as pip2 does with Python2. pip operates in whichever environment is appropriate to the context. For example, if you are in a Python3 venv, pip will operate on the Python3 environment.

$(".btncancel").button({ disabled: true });

Here 'btncancel' is the class name of the button.

It depends on the type of data you need access to. If you have some kind of data pool that needs to persist across Activitys then Erich's answer is the way to go. If you just need to pass a few objects from one activity to another then you can have them implement Serializable and pass them in the extras of the Intent to start the new Activity.

Thanks to DroidT, I made this:

I realize that if the Fragment does not execute onCreateView(), its view is not instantiated. So, if the fragment on back stack did not create its views, I save the last stored state, otherwise I build my own bundle with the data I want to save/restore.

1) Extend this class:

import android.os.Bundle;
import android.support.v4.app.Fragment;

public abstract class StatefulFragment extends Fragment {

    private Bundle savedState;
    private boolean saved;
    private static final String _FRAGMENT_STATE = "FRAGMENT_STATE";

    @Override
    public void onSaveInstanceState(Bundle state) {
        if (getView() == null) {
            state.putBundle(_FRAGMENT_STATE, savedState);
        } else {
            Bundle bundle = saved ? savedState : getStateToSave();

            state.putBundle(_FRAGMENT_STATE, bundle);
        }

        saved = false;

        super.onSaveInstanceState(state);
    }

    @Override
    public void onCreate(Bundle state) {
        super.onCreate(state);

        if (state != null) {
            savedState = state.getBundle(_FRAGMENT_STATE);
        }
    }

    @Override
    public void onDestroyView() {
        savedState = getStateToSave();
        saved = true;

        super.onDestroyView();
    }

    protected Bundle getSavedState() {
        return savedState;
    }

    protected abstract boolean hasSavedState();

    protected abstract Bundle getStateToSave();

}

2) In your Fragment, you must have this:

@Override
protected boolean hasSavedState() {
    Bundle state = getSavedState();

    if (state == null) {
        return false;
    }

    //restore your data here

    return true;
}

3) For example, you can call hasSavedState in onActivityCreated:

@Override
public void onActivityCreated(Bundle state) {
    super.onActivityCreated(state);

    if (hasSavedState()) {
        return;
    }

    //your code here
}

  @include border-radius(0);  // remove border-radius in iOS
}

If you are using laragon open the php.ini

In the interface of laragon menu-> php-> php.ini

when you open the file look for ; extension_dir = "./"

create another one without **; ** with the path of your php version to the folder ** ext ** for example

extension_dir = "C: \ laragon \ bin \ php \ php-7.3.11-Win32-VC15-x64 \ ext"

change it save it

You can also use the logname command from the BSD General Commands Manual under Linux or MacOS to see the username of the user currently logged in, even if the user is performing a sudo operation. This is useful, for instance, when modifying a user's crontab while installing a system-wide package with sudo: crontab -u $(logname)

Per man logname:

LOGNAME(1)

NAME
    logname -- display user's login name

If you want to log inside JSX you can create a dummy component
which plugs where you wish to log:

const Console = prop => (
  console[Object.keys(prop)[0]](...Object.values(prop))
  ,null // ? React components must return something 
)

// Some component with JSX and a logger inside
const App = () => 
  <div>
    <p>imagine this is some component</p>
    <Console log='foo' />
    <p>imagine another component</p>
    <Console warn='bar' />
  </div>

// Render 
ReactDOM.render(
  <App />,
  document.getElementById("react")
)

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.8.4/umd/react.production.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.8.4/umd/react-dom.production.min.js"></script>
<div id="react"></div>

None of the other answers dealt with the case of using .children() or .find(">") to only search for immediate children of a parent element. So, I created a jsPerf test to find out, using three different ways to distinguish children.

As it happens, even when using the extra ">" selector, .find() is still a lot faster than .children(); on my system, 10x so.

So, from my perspective, there does not appear to be much reason to use the filtering mechanism of .children() at all.

Another example:

Dim myPath As String = """" & Path.Combine(part1, part2) & """"

Good luck!

This question is quite old, but with Hibernate 5.1.10, there are some new better comfortable solution.

Lazy loading works except for the parent side of a @OneToOne association. This is because Hibernate has no other way of knowing whether to assign a null or a Proxy to this variable. More details you can find in this article

• You can activate lazy loading bytecode enhancement
• Or, you can just remove the parent side and use the client side with @MapsId as explained in the article above. This way, you will find that you don’t really need the parent side since the child shares the same id with the parent so you can easily fetch the child by knowing the parent id .

An enum type is a type whose fields consist of a fixed set of constants. Common examples include compass directions (values of NORTH, SOUTH, EAST, and WEST) and the days of the week.

public enum Day {
    SUNDAY, MONDAY, TUESDAY, WEDNESDAY,
    THURSDAY, FRIDAY, SATURDAY 
}

You should use enum types any time you need to represent a fixed set of constants. That includes natural enum types such as the planets in our solar system and data sets where you know all possible values at compile time—for example, the choices on a menu, command line flags, and so on.

Here is some code that shows you how to use the Day enum defined above:

public class EnumTest {
    Day day;

    public EnumTest(Day day) {
        this.day = day;
    }

    public void tellItLikeItIs() {
        switch (day) {
            case MONDAY:
                System.out.println("Mondays are bad.");
                break;

            case FRIDAY:
                System.out.println("Fridays are better.");
                break;

            case SATURDAY: case SUNDAY:
                System.out.println("Weekends are best.");
                break;

            default:
                System.out.println("Midweek days are so-so.");
                break;
        }
    }

    public static void main(String[] args) {
        EnumTest firstDay = new EnumTest(Day.MONDAY);
        firstDay.tellItLikeItIs();
        EnumTest thirdDay = new EnumTest(Day.WEDNESDAY);
        thirdDay.tellItLikeItIs();
        EnumTest fifthDay = new EnumTest(Day.FRIDAY);
        fifthDay.tellItLikeItIs();
        EnumTest sixthDay = new EnumTest(Day.SATURDAY);
        sixthDay.tellItLikeItIs();
        EnumTest seventhDay = new EnumTest(Day.SUNDAY);
        seventhDay.tellItLikeItIs();
    }
}

The output is:

Mondays are bad.
Midweek days are so-so.
Fridays are better.
Weekends are best.
Weekends are best.

Java programming language enum types are much more powerful than their counterparts in other languages. The enum declaration defines a class (called an enum type). The enum class body can include methods and other fields. The compiler automatically adds some special methods when it creates an enum. For example, they have a static values method that returns an array containing all of the values of the enum in the order they are declared. This method is commonly used in combination with the for-each construct to iterate over the values of an enum type. For example, this code from the Planet class example below iterates over all the planets in the solar system.

for (Planet p : Planet.values()) {
    System.out.printf("Your weight on %s is %f%n",
                      p, p.surfaceWeight(mass));
}

In addition to its properties and constructor, Planet has methods that allow you to retrieve the surface gravity and weight of an object on each planet. Here is a sample program that takes your weight on earth (in any unit) and calculates and prints your weight on all of the planets (in the same unit):

public enum Planet {
    MERCURY (3.303e+23, 2.4397e6),
    VENUS   (4.869e+24, 6.0518e6),
    EARTH   (5.976e+24, 6.37814e6),
    MARS    (6.421e+23, 3.3972e6),
    JUPITER (1.9e+27,   7.1492e7),
    SATURN  (5.688e+26, 6.0268e7),
    URANUS  (8.686e+25, 2.5559e7),
    NEPTUNE (1.024e+26, 2.4746e7);

    private final double mass;   // in kilograms
    private final double radius; // in meters
    Planet(double mass, double radius) {
        this.mass = mass;
        this.radius = radius;
    }
    private double mass() { return mass; }
    private double radius() { return radius; }

    // universal gravitational constant  (m3 kg-1 s-2)
    public static final double G = 6.67300E-11;

    double surfaceGravity() {
        return G * mass / (radius * radius);
    }
    double surfaceWeight(double otherMass) {
        return otherMass * surfaceGravity();
    }
    public static void main(String[] args) {
        if (args.length != 1) {
            System.err.println("Usage: java Planet <earth_weight>");
            System.exit(-1);
        }
        double earthWeight = Double.parseDouble(args[0]);
        double mass = earthWeight/EARTH.surfaceGravity();
        for (Planet p : Planet.values())
           System.out.printf("Your weight on %s is %f%n",
                             p, p.surfaceWeight(mass));
    }
}

If you run Planet.class from the command line with an argument of 175, you get this output:

$ java Planet 175
Your weight on MERCURY is 66.107583
Your weight on VENUS is 158.374842
Your weight on EARTH is 175.000000
Your weight on MARS is 66.279007
Your weight on JUPITER is 442.847567
Your weight on SATURN is 186.552719
Your weight on URANUS is 158.397260
Your weight on NEPTUNE is 199.207413

     subprocess.Popen(cmd.split(), stderr=subprocess.STDOUT, stdout=subprocess.PIPE)

This will create an image for every page and store them as temp-0.png, temp-1.png .... This is only 'extraction' if you got a pdf with only images and no text.

I would extend this question with a NDIS driver example on getting time. As one knows, KeQuerySystemTime (mimicked under NdisGetCurrentSystemTime) has a low resolution above milliseconds, and there are some processes like network packets or other IRPs which may need a better timestamp;

The example is just as simple:

LONG_INTEGER data, frequency;
LONGLONG diff;
data = KeQueryPerformanceCounter((LARGE_INTEGER *)&frequency)
diff = data.QuadPart / (Frequency.QuadPart/$divisor)

where divisor is 10^3, or 10^6 depending on required resolution.

After this, From File Menu select Save Book ,from next menu select "Excel 97-2003 Add-In (*.xla)

It will save as Excel Add-In. that will be available till the Ms.Office Installation to that machine.

Now Open any Excel File in any Cell type =WordNum(<your numeric value or cell reference>)

you will see a Words equivalent of the numeric value.

This Snippet of code is taken from: http://en.kioskea.net/forum/affich-267274-how-to-convert-number-into-text-in-excel

Download the jar file from here

now put it into your libs folder, right click it and select 'Add as library'

now in main.xml put this code

 <com.devsmart.android.ui.HorizontalListView
    android:id="@+id/hlistview"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    />

now in Activity class if you want Horizontal Listview with images then put this code

  HorizontalListView hListView = (HorizontalListView) findViewById(R.id.hlistview);
    hListView.setAdapter(new HAdapter(this));


 private class HAdapter extends BaseAdapter {

    LayoutInflater inflater;

    public HAdapter(Context context) {
        inflater = LayoutInflater.from(context);

    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return Const.template.length;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        HViewHolder holder;
        if (convertView == null) {
            convertView = inflater.inflate(R.layout.listinflate, null);
            holder = new HViewHolder();
            convertView.setTag(holder);

        } else {
            holder = (HViewHolder) convertView.getTag();
        }
        holder.img = (ImageView) convertView.findViewById(R.id.image);
        holder.img.setImageResource(Const.template[position]);
        return convertView;
    }

}

class HViewHolder {
    ImageView img;
}

ORDER BY a date type does not depend on the date format, the date format is only for showing, in the database, they are same data.

Try autoplay="autoplay" instead of the "true" value. That's the documented way to enable autoplay. That sounds weirdly redundant, I know.

It worked for me..add on top of .htaccess file. It would disable FastCGI on godaddy shared hosting account.

It was already mentioned, but thought I could add to using touch

If you touch all the source files to be compiled, the touch command changes the timestamps of a file to the system time the touch command was executed.

The source file timstamp is what make uses to "know" a file has changed, and needs to be re-compiled

For example: If the project was a c++ project, then do touch *.cpp, then run make again, and make should recompile the entire project.

For windows universal apps Path.GetFullPath() is not available, you can use the System.Uri class instead:

 Uri uri = new Uri(Path.Combine(@"C:\blah\",@"..\bling"));
 Console.WriteLine(uri.LocalPath);

I like the last two answers, but I experienced an issue if the the subclass referenced "this" in ngOnDestroy.

I modified it to be this, and it looks like it resolved that issue.

export abstract class BaseComponent implements OnDestroy {
    protected componentDestroyed$: Subject<boolean>;
    constructor() {
        this.componentDestroyed$ = new Subject<boolean>();
        let f = this.ngOnDestroy;
        this.ngOnDestroy = function()  {
            // without this I was getting an error if the subclass had
            // this.blah() in ngOnDestroy
            f.bind(this)();
            this.componentDestroyed$.next(true);
            this.componentDestroyed$.complete();
        };
    }
    /// placeholder of ngOnDestroy. no need to do super() call of extended class.
    ngOnDestroy() {}
}

Ensure position is on your element and set the z-index to a value higher than the elements you want to cover.

element {
    position: fixed;
    z-index: 999;
}

div {
    position: relative;
    z-index: 99;
}

It will probably require some more work than that but it's a start since you didn't post any code.

The errors in ASP.Net are saved on the Server.GetLastError property,

Or i would put a label on the asp.net page for displaying the error.

try
{
    do something
}
catch (YourException ex)
{
    errorLabel.Text = ex.Message;
    errorLabel.Visible = true;
}

1. Go to the site-packages directory where pip is installing your packages.
2. You should see the egg file that corresponds to the package you want to uninstall. Delete the egg file (or, to be on the safe side, move it to a different directory).
3. Do the same with the package files for the package you want to delete (in this case, the psycopg2 directory).
4. pip install YOUR-PACKAGE

None of these answer were working for me on my macbook pro. So what i had to do was go to:

Preferences -> Source Code -> Code Formatting -> C# source code.

From here I could change my style and spacing tabs etc. This is the only project i have where the lead developer has different formatting than i do. It was a pain in the butt that my IDE would format my code different than theirs.

From http://www.peterbe.com/plog/uniqifiers-benchmark:

def f5(seq, idfun=None):  
    # order preserving
    if idfun is None:
        def idfun(x): return x
    seen = {}
    result = []
    for item in seq:
        marker = idfun(item)
        # in old Python versions:
        # if seen.has_key(marker)
        # but in new ones:
        if marker in seen: continue
        seen[marker] = 1
        result.append(item)
    return result

After reading the whole discussion looking for a way to authorize communication to all IP addresses as in my case the IP address to where the request will be sent is defined by the user in an input text and can not be defined in the configuration file. Here is how I resolved the issue

here are the configuration

config.xml

<platform name="android">
...
        <edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application" xmlns:android="http://schemas.android.com/apk/res/android">
            <application android:networkSecurityConfig="@xml/network_security_config" />
        </edit-config>
        <resource-file src="resources/android/xml/network_security_config.xml" target="app/src/main/res/xml/network_security_config.xml" />
...
</platform>

resources/android/xml/network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true" />
</network-security-config>

The most important piece of code is <base-config cleartextTrafficPermitted="true" /> in <network-security-config> instead of domain-config

You main Index.html file for Angular can use the body tag as the ng-view. Then all you need to do is include a script tag at the bottom of whatever page is being pulled into Index.html by Angular like so:

<script type="text/javascript">
$( function() {
    $( "#mydatepickerid" ).datepicker({changeMonth: true, changeYear: true, 
        yearRange: '1930:'+new Date().getFullYear(), dateFormat: "yy-mm-dd"});
});
</script>

Why overcomplicate things??

df.shape, where df is your DataFrame.

If you have special logic required for the first route only you can do the following:

AppComponent

    loaded = false;

    constructor(private router: Router....) {
       router.events.pipe(filter(e => e instanceof NavigationEnd), take(1))
                    .subscribe((e) => {
                       this.loaded = true;
                       alert('loaded - this fires only once');
                   });

I had a need for this to hide my page footer, which was otherwise appearing at the top of the page. Also if you only want a loader for the first page you can use this.

Javascripts .call() and .apply() methods allow you to set the context for a function.

var myfunc = function(){
    alert(this.name);
};

var obj_a = {
    name:  "FOO"
};

var obj_b = {
    name:  "BAR!!"
};

Now you can call:

myfunc.call(obj_a);

Which would alert FOO. The other way around, passing obj_b would alert BAR!!. The difference between .call() and .apply() is that .call() takes a comma separated list if you're passing arguments to your function and .apply() needs an array.

myfunc.call(obj_a, 1, 2, 3);
myfunc.apply(obj_a, [1, 2, 3]);

Therefore, you can easily write a function hook by using the apply() method. For instance, we want to add a feature to jQuerys .css() method. We can store the original function reference, overwrite the function with custom code and call the stored function.

var _css = $.fn.css;
$.fn.css = function(){
   alert('hooked!');
   _css.apply(this, arguments);
};

Since the magic arguments object is an array like object, we can just pass it to apply(). That way we guarantee, that all parameters are passed through to the original function.

I had this issue after moving my home folder to a new drive on linux. It was fixed by removing .nvm folder and reinstalling nvm

Depending on your project, you might want to consider using EditorConfig (https://editorconfig.org/). There's a Notepad++ plugin which will load an .editorconfig where you can specify "lf" as the mandatory line ending.

I've only started using it, but it's nice so far, and open source projects I've worked on have included .editorconfig files for years. The "EOL Conversion" setting isn't changed, so it can be a bit confusing, but if you "View > Show Symbol > Show End of Line", you can see that it's adding LF instead of CRLF, even when "EOL Conversion" and the lower bottom corner shows something else (e.g. Windows (CR LF)).

I know this is an old question, but I was struggling to do this with a time period over 2 hours, so this might help someone. Also, several of the answers don't actually plot against time, giving equal space whatever the duration.

Firstly, as @jameswarren says, use a scatter graph. Then right-click the horizontal axis and choose Format Axis.

Under Number, select Time, and at this point you may find your scale goes a bit crazy, because it chooses to scale the axis by days. So go back to Axis Options and select Fixed for the Minimum, Maximum and Major unit scales.

To set the unit to hours, type in 1/24 = 0.0416667 (I used half that to get half-hourly increments). To make this start at a round number, multiply it by your preferred number of hours and type that into the Minimum box. In my case 08:00 = 0.333333

I know that this post is old and you figured this out a long time ago, but just to save the people who will read this some time.

You probably forgot to add annotation to the entity you are passing to the endpoint, so Jersey does not know how to process the POJO it receives. Annotate the pojo with something like this:

@XmlRootElement(name = "someName")

I wanted to see a benchmark result of functions mentioned in answers including unutbu's.

Also want to point out that numpy doc recommend to use arr.reshape(-1) in case view is preferable. (even though ravel is tad faster in the following result)

TL;DR: np.ravel is the most performant (by very small amount).

Benchmark

Functions:

• np.ravel: returns view, if possible
• np.reshape(-1): returns view, if possible
• np.flatten: returns copy
• np.flat: returns numpy.flatiter. similar to iterable

numpy version: '1.18.0'

Execution times on different ndarray sizes

+-------------+----------+-----------+-----------+-------------+
|  function   |   10x10  |  100x100  | 1000x1000 | 10000x10000 |
+-------------+----------+-----------+-----------+-------------+
| ravel       | 0.002073 |  0.002123 |  0.002153 |    0.002077 |
| reshape(-1) | 0.002612 |  0.002635 |  0.002674 |    0.002701 |
| flatten     | 0.000810 |  0.007467 |  0.587538 |  107.321913 |
| flat        | 0.000337 |  0.000255 |  0.000227 |    0.000216 |
+-------------+----------+-----------+-----------+-------------+

Conclusion

ravel and reshape(-1)'s execution time was consistent and independent from ndarray size. However, ravel is tad faster, but reshape provides flexibility in reshaping size. (maybe that's why numpy doc recommend to use it instead. Or there could be some cases where reshape returns view and ravel doesn't).
If you are dealing with large size ndarray, using flatten can cause a performance issue. Recommend not to use it. Unless you need a copy of the data to do something else.

Used code

import timeit
setup = '''
import numpy as np
nd = np.random.randint(10, size=(10, 10))
'''

timeit.timeit('nd = np.reshape(nd, -1)', setup=setup, number=1000)
timeit.timeit('nd = np.ravel(nd)', setup=setup, number=1000)
timeit.timeit('nd = nd.flatten()', setup=setup, number=1000)
timeit.timeit('nd.flat', setup=setup, number=1000)

You can ssh to your server and run this command

 ln -s /usr/share/phpmyadmin /var/www/phpmyadmin

It worked for me..

You can add custom colors using bootstrap theming in your config file for example variables.scss and make sure you import that file before bootstrap when compiling.

$theme-colors: (
    "whatever": #900
);

Now you can do .btn-whatever

You have to disable Globals

 /**
 * @backupGlobals disabled

i had problem to run it and i make some changes to run it with mp3 source. here is BackfrounSoundService.java file. consider that my mp3 file is in my sdcard in my phone .

public class BackgroundSoundService extends Service {
    private static final String TAG = null;
    MediaPlayer player;

    public IBinder onBind(Intent arg0) {

        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        Log.d("service", "onCreate");
        player = new MediaPlayer();
        try {
            player.setDataSource(Environment.getExternalStorageDirectory().getAbsolutePath() + "/your file.mp3");
        } catch (IOException e) {
            e.printStackTrace();
        }
        player.setLooping(true); // Set looping
        player.setVolume(100, 100);

    }

    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.d("service", "onStartCommand");
        try {
            player.prepare();
            player.start();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return 1;
    }

    public void onStart(Intent intent, int startId) {
        // TO DO
    }

    public IBinder onUnBind(Intent arg0) {
        // TO DO Auto-generated method
        return null;
    }

    public void onStop() {

    }

    public void onPause() {

    }

    @Override
    public void onDestroy() {
        player.stop();
        player.release();
    }

    @Override
    public void onLowMemory() {

    }
}

It will be faster to just make a HEAD request so no HTML will be fetched.
Also I am sure google would like it better this way :)

try:
    import httplib
except:
    import http.client as httplib

def have_internet():
    conn = httplib.HTTPConnection("www.google.com", timeout=5)
    try:
        conn.request("HEAD", "/")
        conn.close()
        return True
    except:
        conn.close()
        return False

Render method does not necessarily have to return a single element. An array can also be returned.

var indents = [];
for (var i = 0; i < this.props.level; i++) {
  indents.push(<span className='indent' key={i}></span>);
}
return indents;

OR

return this.props.level.map((item, index) => (
    <span className="indent" key={index}>
        {index}
    </span>
));

Docs here explaining about JSX children

OLD:

You can use one loop instead

var indents = [];
for (var i = 0; i < this.props.level; i++) {
  indents.push(<span className='indent' key={i}></span>);
}
return (
   <div>
    {indents}
    "Some text value"
   </div>
);

You can also use .map and fancy es6

return (
   <div>
    {this.props.level.map((item, index) => (
       <span className='indent' key={index} />
    ))}
    "Some text value"
   </div>
);

Also, you have to wrap the return value in a container. I used div in the above example

As the docs say here

Currently, in a component's render, you can only return one node; if you have, say, a list of divs to return, you must wrap your components within a div, span or any other component.

DTO is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.

• DTO should only contain private fields for your data, getters, setters, and constructors.
• DTO is not recommended to add business logic methods to such classes, but it is OK to add some util methods.

DAO is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).

Here is an example of how the DAO and DTO interfaces would look like:

interface PersonDTO {
    String getName();
    void setName(String name);
    //.....
}

interface PersonDAO {
    PersonDTO findById(long id);
    void save(PersonDTO person);
    //.....
}

The MVC is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.

As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

/* get your context */
Context c = getActivity().getApplicationContext();

LinearLayout l = new LinearLayout(c);
l.setOrientation(LinearLayout.VERTICAL);
LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT, 0);

l.setLayoutParams(params);
l.setBackgroundResource(R.drawable.border);

TextView tv=new TextView(c);
tv.setText(" your text here");

/* set typeface if needed */
Typeface tf = Typeface.createFromAsset(c.getAssets(),"fonts/VERDANA.TTF");  
tv.setTypeface(tf);

// LayoutParams lp = new LayoutParams();

tv.setTextColor(Color.parseColor("#282828"));

tv.setGravity(Gravity.CENTER | Gravity.BOTTOM);
//  tv.setLayoutParams(lp);

tv.setTextSize(20);
l.addView(tv);

return l;

>>> print '{0}'.format('5'.zfill(2))
05

http sends/receives data as strings... this is just the way things are. You are looking to parse the string as json.

var jsonObject = JSON.parse(data);

How to parse JSON using Node.js?

The most likely place to find this sort of information is in the event viewer (under Administrative tools in XP or run eventvwr) This is where most services log warnings errors etc.

Add a View:

1. Right-Click View Folder
2. Click Add -> View
3. Click Create a strongly-typed view
4. Select your User class
5. Select List as the Scaffold template

Add a controller and action method to call the view:

public ActionResult Index()
{
    var users = DataContext.GetUsers();
    return View(users);
}

Your @POST method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like:

@XmlRootElement
public class MyJaxBean {
    @XmlElement public String param1;
    @XmlElement public String param2;
}

Then your @POST method would look like the following:

@POST @Consumes("application/json")
@Path("/create")
public void create(final MyJaxBean input) {
    System.out.println("param1 = " + input.param1);
    System.out.println("param2 = " + input.param2);
}

This method expects to receive JSON object as the body of the HTTP POST. JAX-RS passes the content body of the HTTP message as an unannotated parameter -- input in this case. The actual message would look something like:

POST /create HTTP/1.1
Content-Type: application/json
Content-Length: 35
Host: www.example.com

{"param1":"hello","param2":"world"}

Using JSON in this way is quite common for obvious reasons. However, if you are generating or consuming it in something other than JavaScript, then you do have to be careful to properly escape the data. In JAX-RS, you would use a MessageBodyReader and MessageBodyWriter to implement this. I believe that Jersey already has implementations for the required types (e.g., Java primitives and JAXB wrapped classes) as well as for JSON. JAX-RS supports a number of other methods for passing data. These don't require the creation of a new class since the data is passed using simple argument passing.

HTML <FORM>

The parameters would be annotated using @FormParam:

@POST
@Path("/create")
public void create(@FormParam("param1") String param1,
                   @FormParam("param2") String param2) {
    ...
}

The browser will encode the form using "application/x-www-form-urlencoded". The JAX-RS runtime will take care of decoding the body and passing it to the method. Here's what you should see on the wire:

POST /create HTTP/1.1
Host: www.example.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8
Content-Length: 25

param1=hello&param2=world

The content is URL encoded in this case.

If you do not know the names of the FormParam's you can do the following:

@POST @Consumes("application/x-www-form-urlencoded")
@Path("/create")
public void create(final MultivaluedMap<String, String> formParams) {
    ...
}

HTTP Headers

You can using the @HeaderParam annotation if you want to pass parameters via HTTP headers:

@POST
@Path("/create")
public void create(@HeaderParam("param1") String param1,
                   @HeaderParam("param2") String param2) {
    ...
}

Here's what the HTTP message would look like. Note that this POST does not have a body.

POST /create HTTP/1.1
Content-Length: 0
Host: www.example.com
param1: hello
param2: world

I wouldn't use this method for generalized parameter passing. It is really handy if you need to access the value of a particular HTTP header though.

HTTP Query Parameters

This method is primarily used with HTTP GETs but it is equally applicable to POSTs. It uses the @QueryParam annotation.

@POST
@Path("/create")
public void create(@QueryParam("param1") String param1,
                   @QueryParam("param2") String param2) {
    ...
}

Like the previous technique, passing parameters via the query string does not require a message body. Here's the HTTP message:

POST /create?param1=hello&param2=world HTTP/1.1
Content-Length: 0
Host: www.example.com

You do have to be particularly careful to properly encode query parameters on the client side. Using query parameters can be problematic due to URL length restrictions enforced by some proxies as well as problems associated with encoding them.

HTTP Path Parameters

Path parameters are similar to query parameters except that they are embedded in the HTTP resource path. This method seems to be in favor today. There are impacts with respect to HTTP caching since the path is what really defines the HTTP resource. The code looks a little different than the others since the @Path annotation is modified and it uses @PathParam:

@POST
@Path("/create/{param1}/{param2}")
public void create(@PathParam("param1") String param1,
                   @PathParam("param2") String param2) {
    ...
}

The message is similar to the query parameter version except that the names of the parameters are not included anywhere in the message.

POST /create/hello/world HTTP/1.1
Content-Length: 0
Host: www.example.com

This method shares the same encoding woes that the query parameter version. Path segments are encoded differently so you do have to be careful there as well.

As you can see, there are pros and cons to each method. The choice is usually decided by your clients. If you are serving FORM-based HTML pages, then use @FormParam. If your clients are JavaScript+HTML5-based, then you will probably want to use JAXB-based serialization and JSON objects. The MessageBodyReader/Writer implementations should take care of the necessary escaping for you so that is one fewer thing that can go wrong. If your client is Java based but does not have a good XML processor (e.g., Android), then I would probably use FORM encoding since a content body is easier to generate and encode properly than URLs are. Hopefully this mini-wiki entry sheds some light on the various methods that JAX-RS supports.

Note: in the interest of full disclosure, I haven't actually used this feature of Jersey yet. We were tinkering with it since we have a number of JAXB+JAX-RS applications deployed and are moving into the mobile client space. JSON is a much better fit that XML on HTML5 or jQuery-based solutions.

In java.lang.String, the replace method either takes a pair of char's or a pair of CharSequence's (of which String is a subclass, so it'll happily take a pair of String's). The replace method will replace all occurrences of a char or CharSequence. On the other hand, the first String arguments of replaceFirst and replaceAll are regular expressions (regex). Using the wrong function can lead to subtle bugs.

A better option is to add the constraints directly during CREATE TABLE query (assuming you have the information about the tables)

CREATE TABLE products(
    productId INT AUTO_INCREMENT PRIMARY KEY,
    productName varchar(100) not null,
    categoryId INT NOT NULL,
    CONSTRAINT fk_category
    FOREIGN KEY (categoryId) 
    REFERENCES categories(categoryId)
        ON UPDATE CASCADE
        ON DELETE CASCADE
) ENGINE=INNODB;

You have to select the option in ArrayAdapter:

ArrayAdapter<String> adapter = new ArrayAdapter<String>
    (this, android.R.layout.simple_list_item_single_choice, countries);

You'll need to create an Action on your Controller that returns the rendered result of the "UserDetails" partial view or control. Then just use an Http Get or Post from jQuery to call the Action to get the rendered html to be displayed.

1) We usually do not use int data types to height, weight, distance, temperature etc.(variables which can have decimal points) Therefore height, weight should be double or float. but double is more accurate than float when you have more decimal points

2) And instead of ^, you can change that calculation as below using Math.pow()

bmi = (weight/(Math.pow(height/100, 2)));

3) Math.pow() method has below definition

Math.pow(double var_1, double var_2);

Example:

i) Math.pow(8, 2) is produced 64 (8 to the power 2)

ii) Math.pow(8.2, 2.1) is produced 82.986813689753 (8.2 to the power 2.1)

You need to dynamically allocate your matrix. For instance:

int* mat;
int dimx,dimy;
scanf("%d", &dimx);
scanf("%d", &dimy);
mat = malloc(dimx * dimy * sizeof(int));

This creates a linear array which can hold the matrix. At this point you can decide whether you want to access it column or row first. I would suggest making a quick macro which calculates the correct offset in the matrix.

If you want to set width dynamically with variable than use [] braces instead {{}}:

 <div [style.width.px]="[widthVal]"  [style.height.px]="[heightVal]"></div>

 <div [style.width.%]="[widthVal]"  [style.height.%]="[heightVal]"></div>

It was requested that I add this functionality to the stackoverflow R package. Given that it is a tinyverse package (and can't depend on third party packages), here is what I came up with:

#' Bulk import data files 
#' 
#' Read in each file at a path and then unnest them. Defaults to csv format.
#' 
#' @param path        a character vector of full path names
#' @param pattern     an optional \link[=regex]{regular expression}. Only file names which match the regular expression will be returned.
#' @param reader      a function that can read data from a file name.
#' @param ...         optional arguments to pass to the reader function (eg \code{stringsAsFactors}).
#' @param reducer     a function to unnest the individual data files. Use I to retain the nested structure. 
#' @param recursive     logical. Should the listing recurse into directories?

#' @author Neal Fultz
#' @references \url{https://stackoverflow.com/questions/11433432/how-to-import-multiple-csv-files-at-once}
#' 
#' @importFrom utils read.csv
#' @export
read.directory <- function(path='.', pattern=NULL, reader=read.csv, ..., 
                           reducer=function(dfs) do.call(rbind.data.frame, dfs), recursive=FALSE) {
  files <- list.files(path, pattern, full.names = TRUE, recursive = recursive)

  reducer(lapply(files, reader, ...))
}

By parameterizing the reader and reducer function, people can use data.table or dplyr if they so choose, or just use the base R functions that are fine for smaller data sets.

I wrote a little function based on the other answers here:

def pexec(*args):
    return subprocess.Popen(args, stdout=subprocess.PIPE).communicate()[0].rstrip()

Usage:

changeset = pexec('hg','id','--id')
branch = pexec('hg','id','--branch')
revnum = pexec('hg','id','--num')
print('%s : %s (%s)' % (revnum, changeset, branch))

If you have same columns in all your csv files then you can try the code below. I have added header=0 so that after reading csv first row can be assigned as the column names.

import pandas as pd
import glob

path = r'C:\DRO\DCL_rawdata_files' # use your path
all_files = glob.glob(path + "/*.csv")

li = []

for filename in all_files:
    df = pd.read_csv(filename, index_col=None, header=0)
    li.append(df)

frame = pd.concat(li, axis=0, ignore_index=True)

>>> import time
>>> time.ctime(int("1284101485"))
'Fri Sep 10 16:51:25 2010'
>>> time.strftime("%D %H:%M", time.localtime(int("1284101485")))
'09/10/10 16:51'

use FileInputStream's readLine() method to read and parse the returned String to int using Integer.parseInt() method.

The library PCAmixdata has functon splitmix that splits quantitative(Numerical data) and qualitative (Categorical data) of a given dataframe "YourDataframe" as shown below:

install.packages("PCAmixdata")
library(PCAmixdata)
split <- splitmix(YourDataframe)
X1 <- split$X.quanti(Gives numerical columns in the dataset) 
X2 <- split$X.quali (Gives categorical columns in the dataset)
