Unwanted knowledge

As the days go by, more and more I realize that there won’t be enough time for me to learn everything I wish to know. The irony is that this is the one thing I wish I didn’t know.


Water: A Worthy Cause

I found this on Twitter and thought I should spread the word. It is a charity campaign to fund clean water on developing countries.

Help Alyssa reach her goal. Even if you can’t donate, you can help by spreading the word.



DB2 Control Center on Linux shows blank window

Man, I hadn’t posted anything in a while.

Anyway, I was having trouble getting the DB2 Control Center (db2cc) to work on Ubuntu 8.04 (Hardy.) Whenever I tried to run db2cc all I was getting was a blank gray window and found that setting the following variable makes it work:


You can set this automatically by adding the following to your .bashrc or .profile file:

export AWT_TOOLKIT=MToolkit

By the way, I found this quick solution on this forum. Hope this helps.

Updating RubyGems on OS X

I just took a peek at the Ruby on Rails site and version 2.2 is almost out. Since I haven’t been using Ruby or Rails in a while I’ve noticed a lot of changes, so I think I’m gonna start playing with it again – specially since version 2.2 includes i18n, which is what I’ve been waiting for.

So, according to Rails’ creator, I need RubyGems 1.3.1 so I can start playing with Rails 2.2 RC2. Ok, I don’t have a problem with that. Let’s update RubyGems:

$ sudo gem update –system
Updating RubyGems
Bulk updating Gem source index for: http://gems.rubyforge.org/
Nothing to update

Hmm. I’m pretty sure I don’t have the newest version, but I’ll check anyway just in case.

$ gem -v

I thought so. So how come I can’t update? After doing a google search I found I had to try this:

$ sudo gem install rubygems-update
Bulk updating Gem source index for: http://gems.rubyforge.org/
Successfully installed rubygems-update-1.3.1
1 gem installed

$ sudo update_rubygems

RubyGems installed the following executables:
If `gem` was installed by a previous RubyGems installation, you may need
to remove it by hand. 

Let’s just do a quick check:

$ gem -v

There we go! Now we’re ready for Rails 2.2 RC2.
