I presented about distributed systems at the University Politehnica of Bucharest. Here are the slides, with thanks to the inspiration sources all over the web (Mahout presentations, HBase and Hadoop presentations).
There’s a new blog post up on hstack.org – Hadoop and HBase Automated Deployment using Puppet, written by yours truly. It also announces the open-sourcing of the code that we use to deploy a fully distributed system to one or more clusters in a semi-automated manner (we need to push the button 
)
So, enjoy reading here.

My colleague Andrei just posted a great article about HBase performance, complete with numbers and pictures over on http://hstack.org/. If you’re into the all NoSQL movement, you should definetly check it out (and I’m not just saying it because I know him )
Problem: The default keyboard shortcut for duplicating lines (ALT + CTRL + Up/Down) does not work
Configuration: Ubuntu Jaunty, Eclipse 3.5
This is caused by the system using the same shortcuts to move to a virtual workspace above and below. Go to System > Preferences > Keyboard Shortcuts and assign a different key combo for the following two actions:
Switch to workspace up
Switch to workspace down
Duplicate lines works again.

Aim: when hitting F4 in GnomeCommander, the file will open in a new tab of the existing gvim instance:
Options1: visual:
- Open Gnome Commander => Settings => Options => Programs
- In the Edit text field put this:
gvim -p --remote-tab-silent %s
- Save and restart Gnome Commander – not always needed, but helps
Option 2: editing the settings file:
- The file to edit is ~/.gnome2/gnome-commander
- Find the line :editor=blablabla and change it to :
editor=gvim -p --remote-tab-silent %s
- Save and restart gnome-commander
