autocomplete - Disable bash tab completion - Unix & Linux Stack Exchange | https://unix.stackexchange.com/
Dennis' solution
<code class="language-bash">
bind 'set disable-completion on'
</code>

can be done on the fly in Bash as well. You do not need to put it in .bashrc.

Musta's solution (bash --noediting) works but also disables command line editing.

Another way is
<code class="language-bash">
bind -u complete
</code>

(unset key binding associated with 'complete')

You can make readline (and bash) much more user friendly by adding a few options to ~/.inputrc : commandline | https://www.reddit.com/
set completion-prefix-display-length 2

This one is insanely useful when you have a folder with lots of similarly named files and you are not sure how far the completion has gone when you press TAB. The first part that has been completed will be replaced by "...", and it is simple to see what you need to type to finish the completion.

Interesting, but doesn't work for me.
By default, C-x C-r is bound to re-read-init-file.

See the Bash Reference Manual for explanation.

webdav - How do I enable HTTP-DAV in Apache? - Server Fault | https://serverfault.com/
Yup, I made this mistake, too:
I finally figured it out.

Instead of
<code class="language-apache"><Location /var/www/html/updates>
Dav On
</Location></code>

it needs to be (Directory instead of Location)
<code class="language-apache"><Directory /var/www/html/updates>
Dav On
</Directory></code>

Mailing List Archive: Re: MediaWiki 1.28.0 Extension LDAPAuthentication does not work | https://lists.gt.net/
There is a new permission available that governs the right to create accounts when logging in with an external user account. It's called "autocreateaccount" [0]. You have to add to your config something like:
<code class="language-php">$wgGroupPermissions['*']['autocreateaccount'] = true;</code>

Or maybe this is enough:
<code class="language-php">$wgGroupPermissions['user']['autocreateaccount'] = true;</code>

php - Removing X-Powered-By - Stack Overflow | https://stackoverflow.com/

I think that is controlled by the expose_php setting in PHP.ini:
<code class="language-php">expose_php = off</code>

Decides whether PHP may expose the fact that it is installed on the server (e.g. by adding its signature to the Web server header). It is no security threat in any way, but it makes it possible to determine whether you use PHP on your server or not.

There is no direct security risk, but as David C notes, exposing an outdated (and possibly vulnerable) version of PHP may be an invitation for people to try and attack it.

numpy - Automatically import modules when entering the python or ipython interpreter - Stack Overflow | https://stackoverflow.com/
Use the environment variable PYTHONSTARTUP. From the official documentation:
If this is the name of a readable file, the Python commands in that file are executed before the first prompt is displayed in interactive mode. The file is executed in the same namespace where interactive commands are executed so that objects defined or imported in it can be used without qualification in the interactive session.

Manual:Short URL/Apache - MediaWiki | https://www.mediawiki.org/
In the Apache config (for the vhost or whatever):
<code class="language-apache">## http://www.mediawiki.org/wiki/Manual:Short_URL/Apache

# Enable the rewrite engine
RewriteEngine On

# Short URL for wiki pages
RewriteRule ^/?wiki(/.*)?$ %{DOCUMENT_ROOT}/w/index.php [L]

# Redirect / to Main Page
RewriteRule ^/*$ %{DOCUMENT_ROOT}/w/index.php [L]
</code>

In 'LocalSettings.php':
<code class="language-php">
## https://www.mediawiki.org/wiki/Manual:Short_URL
$wgScriptPath = "/w"; // this should already have been configured this way
$wgArticlePath = "/wiki/$1";

vagrantfile - Print message after booting vagrant machine with "vagrant up" - Stack Overflow | https://stackoverflow.com/
Vagrant now has builtin support for a message to appear after vagrant up. Just add this to your Vagrantfile:

<code class="language-ruby">config.vm.post_up_message = "This is the start up message!"</code>

And then after your VM has come up you'll see this message in green:

<code>==> default: Machine 'default' has a post `vagrant up` message. This is a message
==> default: from the creator of the Vagrantfile, and not from Vagrant itself:
==> default:
==> default: This is the start up message!</code>
