Just because I struggle every time to find how to do that, here’s the procedure to delete an event without responding :
BAM ! DONE !
The goal of this tutorial is to show you how to create an encrypted LVM on Linux. This will help you keep your data safe in the event of, for example, your laptop computer being stolen.
Here are a couple of pointers to perform an installation of OpenBSD on a media which will be read-only most of the times. I hope I didn’t forget anything otherwise I’ll be in trouble next time I reinstall… 
Or why you usually use ls -l *txt without quotes, but use quotes in find . -name "*txt".
Spotify is a great way to listen to music. Unfortunately the official client only runs on Windows and Mac machines. There is an experimental unsupported client for linux, however it’s provided as a DEB (ubuntu/debian) package.
Here’s a gross hack for whom is desperate to get it working on Gentoo.

… or anyone else really, with a little trick to implement a black list and filter unwanted callers.

GoogleVoice (GV for short) is a great service (I won’t go into the details, but you can read up about it here), but it is unfortunately accessible only if you are in the USA.
Granted there is already plenty of documentation about how to circumvent this, but I’m not aware of any of those using Asterisk.
So this post will document how to sign up for a GV account as well as how to use it with Asterisk afterwards, in the prospect of using it if you are not in the USA.
In order to be able to sign up for GV, you need to meet 2 prerequisites :
Step 1 is left as an exercise to the reader (“Good luck ! I’m behind 7 proxies !” 
).
Step 2 is the one we’re going to describe here, as an example of what you can pull with simple Asterisk configurations.
A non-printing character is a character which won’t actually get directly printed (or displayed) but rather interpreted. Such non-printing characters are for example line-feed or tabulation. The interpretation of those characters can differ from one system to the next. For example the line-feed character is different on Unix or DOS.
If you need an easy way to confirm that a text file is DOS or UNIX formatted (they differ with respect to the end of line character(s) for example) or if you wish to display normally non-printing characters of a text file, you can use the -vET command line switches of the cat utility.
As explained in the man page :

If like me you get tons of telemarketers calls, there’s an easy way to get rid of them with a quick Asterisk hack. The following Asterisk configuration snippet will immediately send any hidden caller ID (99% telemarketers, and I have a general policy of not picking up the phone for hidden caller ID anyway) to a holding music making them waste money and time…
This post is meant to clarify a few key concepts about Unix filesystems such as directory permissions, hardlinks and symlinks.
