Is This Right?
I just re-installed Ubuntu on my desktop at work. I obviously installed Ruby and Rails using the script that I wrote. What’s interesting here is that if you see the video below (No sound, I was at work and I’m waiting for UPS to deliver my new mic), you’ll see that libxml-ruby gem does not exist on the machine. Yet, when I start the irb, I can use ‘xml/libxml’. I nevertheless installed libxml-ruby gem and nothing changes. By the way, the error messages you’re seeing is on rdoc/documentation, not on the gem install, so it’s okay.
is this right? from Joon You on Vimeo.
Is this right? The answer is yes. It’s because when I install Ruby, I also install the Libxml binding, therefore it does not show up on the list of gems because it’s NOT a gem at this point.
Not a big deal, but I found this interesting…
Corey Haines’ Pair-Programming Tour
This video series of Corey Haines’ Pair-Programming Tour features interviews with some of the most respected people in Ruby community. It is so cool that Corey came up with this awesome idea of doing a tour of pair-programming while “forced freelancing”.
Screencasting with VLC in Linux Demo
** Update **
The WordPress engine screws up the command listed below. Please enter it manually to get it to work correctly.
Here’s where I got the information, http://www.nerdlogger.com/2008/01/stream-your-linuxwindowsmac-desktop-as.html where he describes the command in more details.
The only thing that’s different that I do is rather than stream, I send the screen stream to a file by doing this:
vlc screen:// screen-fps=30 –sout ‘#transcode{vcodec=mp4v, vb=4096, scale=1, width=600, height=400}:std{access=file, url=”linux_screen.mp4″}’

Creating XML Using Libxml Screencast
Here’s an introduction to libxml. In this screencast, I create a simple xml document using libxml. I’m learning how to do this, so please be kind and I promise I’ll get better as the time goes by.
If you’d like to get the original video in higher quality along with the file, please email me at joon at this domain, I’ll send you the link to download. You can also do the same if you’d like a Rubyhead working on your next project.
Merry Christmas
I would like to wish everyone Merry Christmas and Happy New Year. Starting new year, I’ll be using this blog as a video diary for things I learn or find interesting on daily basis.
Rails & Merb Merging => Rails 3
Rails and Merb are merging. This really doesn’t come as a shock considering all the participants. I’m really curious to see how this is going to turn out. These two frameworks have a couple of fundamental differences outside of ActiveRecord vs. DataMapper. We DO live in exciting time!
Here’s the link to the announcement.
Emacs Peepcode
Now that I have up on emacs, Peepcode releases emacs screencast. Take a look. I will.
By the way, I only use Vim on Linux. I still mainly use TextMate and will until there’s a compelling reason not to. I just don’t get the latest trend to use other editors. As far as I’m concerned, TextMate is the best editor I’ve ever used, and trust me, I used just about everything on the planet.

Installing Ruby & Rails Script for Ubuntu 8.04LTS Hardy Heron
A colleague at work suggest that I should write a small script that installs Ruby and Rails on Ubuntu Hardy Heron 8.04LTS since the instruction is already here.
After you unzip it, change the permission via “chmod +x installruby” to execute.
Appreciation for Ruby
Cinderella once sang “don’t know what you got, until it’s gone…” Well, at work, I’ve been back to programming in, of all things, C++ past two weeks. Even bigger kick in the ass is that I also have to work on a Windows app written with MFC! Yes, MFC!
I can’t tell you how much I miss Ruby.
Even with my proficiency in C/C++, it takes much longer to do the same thing. Yeah, I know about the performance, but really, if the user/system sees little or no difference, who cares? Ruby is so much more natural to me that it doesn’t feel like I’m writing computer codes.
Ok, but it’s not all that bad. I’m still trying to get rid of my “thinking in C” syndrome, so I’m not really feeling much pain. This whole experience has given me much more appreciation for Ruby though, and I just hope that after this project is done, I won’t have to go back.
