这是一个有关Linux视频教程的部落格。我将在此与大家分享经验与所学。请多多赐教。
This is mainly a Video Tutorial Blog about Linux. I am here to share my learnings and experiences. May I invite you to join me in this Quest.
It all started with Linux Mint 11 and my move from the dark-side to freedom. Also a move to share experiences, knowledge and community spirit.
I started to share my new found knowledge and experience in various different forums - Linux Mint Community, TomatoUSB and places I chance upon when googling.
As my journey and voyages become more disperse and frequent, I decided its time for a place and certain ways to tie things together.
Thus, the birth of my blog "Guruwannabe" - my user-name at Linux Mint Community, the first place that I became serious about my cyber-presence.

Introduction
Hi Guys,
Introducing Linux Mint Simply Beautiful!
Well, I have decided to start a new series in Bite-Size Linux, Day-by-Day to capture the beauty of using Linux Mint, its simple and elegant experience.
All these while we are still Celebrating our Chinese Lunar New Year in Singapore.
It has been a rewarding experience learning more about Video Editing in Linux. Jumping from a variety of tools to get things done up: RecordMyDesktop, XVidCap, PiTiVi, Kdenlive, and how Xdamage affect Video Editing.
And most importantly, it's been a joy to be able to present you the finish product.
May your quest in Linux made more enjoyable and interesting!
Yours sincerely,
Blessed Beloved Bob (Guruwannabe)

Hydrogen Drum Machine 0.9.4.2 Introduction
When I started this video tutorial, I thought I was giving you a short work-around for Hydrogen Drum Machine if you also experience a similar weird encounter with MIDI and Sound in Linux.
As far as Desktop Audio and Video experience in LinuxMint11 is concerned, everything works excellent.
Movies, DVDs, Youtube, Grooveshark, MP3s all works seamlessly out-of-the box.
Beyond that... a complex Sound System Architecture awaits.
Problem / Challenge
The Problem or Challenge we are facing in this simple tutorial is Weird sound, strange sound or no sound coming from Hydrogen Drum Machine. Hey guys, Hydrogen is an excellent piece of software. To my blessings, I have personally tasted it when reviewing various different Linux Distro Live CDs. So, I know it works beautifully eventhough I do not have much musical experience.
Until I started my video screen-capturing did I discover that it's weirder than I realised.
