Twitter Java APIs: JTwitter vs. Twitter4J

I recently stumbled upon a twitter API called JTwitter. It looks as interesting as the Twitter4J API, which I'm using to write a Twitter Java application for my boss. It should be interesting to have a list of all the available APIs for Twitter, and make some comparisons...

Something messed up my classpath in Netbeans 6.8

I was working with a Twitter Java app in NetBeans, and suddenly I couldn't run my project from NetBeans 6.8. The strange thing was that I could compile it on NetBeans and then run the jar file on a terminal window!  After two stinking hours of struggling with my project configuration, I found out it was a problem with the classpath, thanks to the tips I found on http://en.allexperts.com/q/Java-1046/main-class.htm.

So, basically, if suddenly you cannot run projects on NetBeans, try fixing up your classpath, and maybe your problem will be solved.

On Windows, type

 set CLASSPATH=.;%CLASSPATH%

on a Command Prompt window.

On Linux, type

CLASSPATH=.:$CLASSPATH
export CLASSPATH

On a terminal window.

Problem with Ubuntu 9.10 Karmic and 1024x768 screen resolution solved

Geez, I had a lot of trouble these last two days because I installed Ubuntu 9.10 Karmic and my PC was stuck at 800x600 resolution, even though I could get up to 1024x768 on Ubunu 9.04 Jaunty. After two days and several anxiety attacks, I finally discovered that it all was due to a loose connection between the graphics adapter and the monitor! How about that? I never had a problem like this before...

Ubuntu Server, VirtualBox and PAE extensions

A few minutes ago I had some trouble when creating a new virtual machine with Ubuntu 8.04 LTS edition through the VBoxManage interface. Thanks to the http://www.networkfoo.org/server-infrastructure/ubuntu-server-install-virtualbox-kernel-requires-following-features-not-presen post, I discovered I needed to activate the PAE extensions.
