Hardy to Intrepid

Sunday, November 2nd, 2008

I was planning on giving it a week before upgrading my desktop to the new Ubuntu 8.10 Intrepid Ibex, but couldn’t find better things to do on the mild sunny classic Virginian Saturday afternoon than hunching over a computer in the darkest corner of a basement… more…

Hooked up my new 24″ LCD – suprisingly easy

Sunday, August 10th, 2008

I’ve wanted to replace one of the dual-19″ LCDs with a widescreen for a while. So Today I picked up the Samsung 2443BWX $349.99 special Costco is running. I had thought hooking it up to my dual-head setup would be some pain because it would have to run under 1920×1200 while the other 19″ under 1280×1024. Well, it worked out surprisingly easy in both Windows and Linux. In Windows, it was trivially done via the display settings. In Linux, all I had to do was replace this line in the xorg.conf:

Option "metamodes" "DFP-0: nvidia-auto-select +1280+0, DFP-1: nvidia-auto-select +0+0"


Option "metamodes" "DFP-0: nvidia-auto-select +1920+0, DFP-1: nvidia-auto-select +0+0"

and restart the X server.

The UnknownHostException and A Not-so-obvious Cause

Monday, June 9th, 2008

The past week has turned out to be the week of “all sorts of weird problems” for me. One of the issues I ran into was that, in a new Ubuntu installation, maven fails to download artifacts from the repository server. After some arm-twisting with maven (people really should start logging the actually exception instead of just printing “unable to download artifact…”), I was able to pinpoint the underlying problem to be an UnknownHostException from trying to resolve the repository server. The strangeness of the situation is, I can access the repo and download the same artifact with firefox, wget, or anything non-java. I can also resolve the repo server name just fine with nslookup. more…

Why does the GWT compiler require an X server and how to work around it

Got this error today when trying to build our little GWT application in linux: more…

Ubuntu 8.04 Upgrade Goes Well, Not Without Issues

Saturday, May 3rd, 2008

Upgraded from 7.10 to 8.04 last week. The Upgrade went quite smooth, especially considering I have been running a mixed kde 4/kde 3 setup, with the kde 4 pulled directly from the kde.org repo.

My Ubuntu Experience: Java

Wednesday, November 15th, 2006

I’ll catch up later the couple of “episodes” which I’m skipping over and jumping to the Java set up part. Ubuntu comes with gcj and other GNU-based java facilities, which mostly are still only equivalent to JDK 1.4.x. So they needed to get chucked right away, and replaced with the Sun JDK 5. It’s pretty straightforward to install JDK 5, Eclipse, and the rest of the arsenal I work with on the daily basis. The only part involving manual setting was when enabling the Java Plugin and Web Start in Firefox. Here’s The Plugin Portion of it. more…
