Build latest ffmpeg and all (generally) needed codecs from source

ffmpeg

In projects where you need to work with video data - converting video files or creating frame screenshot preview for a video, convert mp3 etc. it is very likely you will decide to use ffmpeg.
It is open source and free lib that is de-facto standard tool to operate with media files. But in Linux repositories it is often outdated version of ffmpeg and to get most recent features you'd better compile it from source. It is not a trivial things to get all needed dependencies, that's why I have gathered it all in one bash script.

Learning Node.JS

Collection of free resources to dive into Node.js.

I prefer quite small, useful and clear articles/books (and I would not be so clever to post official docs links here, I hope you have already found it and know what to do in case of emergency :)).
I'll try to order it from very basic to more sophisticated, so if you don't know where to start... just start from the very beginning of the list.

Autoupdate VirtualBox Guest Additions in Vagrant

vagrant

While using Vagrant (I'll leave the question "Why should I use it?" for some future post) and taking ready made Boxes from http://vagrantbox.es - the fist issue I have faced was a warning about inconsistency of VirtualBox Guest Additions and actual VirtualBox version I am using.

Why is this happening ?

Because VirtualBox Guest Additions - it is drivers etc. installed inside the Box (that you are downloading somewhere) and for each new VirtualBox version new Guest Additions are required.
It can work with old version in general, but very essential parts could fail - like shared folders etc.

How to fix it manually

You could go to VirtualBox downloads server and find yourself needed ISO, download it inside Vagrant box via wget for example, mount it and install. But it is boring :)

Autoupdate Guest Additions via Vagrant plugin

vagrant-vbguest comes to help us with it.

Install

vagrant plugin install vagrant-vbguest

Configure

Add one line in your Vagrantfile

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
...
  config.vbguest.auto_update = true
...
end

and restart Vagrant box vagrant up

If you are lucky - everything else will happens automatically and you will be notified about version of Guest Additions that is being installed.

Also go through Configuration docs for vbguest to see other useful params.
