ubuntu hacked

Not Ubuntu but the Ubuntu Forums Been hacked today with attackers having more than 1.8 million account details
Every user’s local username, password, and email address [were stolen] from the Ubuntu Forums database Canonical say in a statement posted on the website, adding that while the passwords (stolen) are not stored in plain text  those who use the same password on other services should change the password on the other service[s] ASAP.

Great news on that are Ubuntu One and Launchpad, are not affected by the breach.

This all happened on Saturday the 20th of july.The main page was redirected to that of an image touting a twitter account – @Spuntn1k_ – and text that read: “You dun goofed, it’s as simple as that”.

So what was the reason behind this? and how did that Happened ?are the main questions hat may arose in everyone's mind...

Some Security Experts specify that this happened due to lack of protection on Backend,also it has been said that the Forum was on an outdated version of vBulletin whose Admin Panel was unsafe.

There's a new question that why do hacker's need to hack any open source system ?why is it necessary?what do they want from an open source system through hacking which they cannot have without hack?

  Here I am publishing some of the greatest ever open source softwares for audio/playback-

Ardour:
Ardour is a hard disk recorder and digital audio workstation application. It runs on Linux, OS X and FreeBSD. Its primary author is Paul Davis, who is also responsible for the JACK Audio Connection Kit. Ardour's intention is to provide digital audio workstation software suitable for professional use.

Audacity won the SourceForge 2007 and 2009 Community Choice Award for Best Project for Multimedia.

Grip:
Grip is a cd-player and cd-ripper for the Gnome desktop. It has the ripping capabilities of cdparanoia builtin, but can also use external rippers (such as cdda2wav). It also provides an automated frontend for MP3 (and other audio format) encoders, letting you take a disc and transform it easily straight into MP3s. Internet disc lookups are supported for retrieving track information from disc database servers.Grip works with DigitalDJ to provide a unified “computerized” version of your music collection.

Streamripper:
With the emergence of file sharing protocols such as Napster, Gnutella, and now Mojonation and Freenet, the average Internet user can download nearly any mp3 he wants in a matter of no time, but many times people don’t know what they want. Streamripper allows you to download an entire station of music. Many of these mp3 radio stations only play certain genres, so you can now download an entire collection of goa/trance music, an entire collection of jazz, punk rock, whatever you want.

soundKonverter is a frontend to various audio converters.

The key features are:
Audio conversion
Replay Gain calculation
CD ripping
