Going Linux, Once and for All

December 23rd, 2009

With the linux experiment coming to an end, and my Vista PC requiring a reinstall, I decided to take the leap and go all linux all the time. To that end, I’ve installed Kubuntu on my desktop PC.

I would like to be able to report that the Kubuntu install experience was better than the Debian one, or even on par with a Windows install. Unfortunately, that just isn’t the case.

My machine contains three 500GB hard drives. One is used as the system drive, while an integrated hardware RAID controller binds the other two together as a RAID1 array. Under Windows, this setup worked perfectly. Under Kubuntu, it crashed the graphical installer, and threw the text-based installer into fits of rage.

With plenty of help from the #kubuntu IRC channel on freenode, I managed to complete the Kubuntu install by running it with the two RAID drives disconnected from the motherboard. After finishing the install, I shut down, reconnected the RAID drives, and booted back up. At this point, the RAID drives were visible from Dolphin, but appeared as two discrete drives.

It was explained to me via this article that the hardware RAID support that I had always enjoyed under windows was in fact a ‘fake RAID,’ and is not supported on Linux. Instead, I need to reformat the two drives, and then link them together with a software RAID. More on that process in a later post, once I figure out how to actually do it.

At this point, I have my desktop back up and running, reasonably customized, and looking good. After trying KDE’s default Amarok media player and failing to figure out how to properly import an m3u playlist, I opted to use Gnome’s Banshee player for the time being instead. It is a predictable yet stable iTunes clone that has proved more than capable of handling my library for the time being. I will probably look into Amarok and a few other media players in the future. On that note, if you’re having trouble playing your MP3 files on Linux, check out this post on the ubuntu forums for information about a few of the necessary GStreamer plugins.

For now, my main tasks include setting up my RAID array, getting my ergonomic bluetooth wireless mouse working, and working out folder and printer sharing on our local Windows network. In addition, I would like to set up a Windows XP image inside of Sun’s Virtual Box so that I can continue to use Microsoft Visual Studio, the only Windows application that I’ve yet to find a Linux replacement for.

This is just the beginning of the next chapter of my own personal Linux experiment; stay tuned for more excitement.

Augmented Reality? Hell Yes

November 29th, 2009

A colleague recently linked me to this TED talk from an Indian computer scientist named Pranav Mistry who has created SixthSense, a new platform that brings mobile computing into real life.

His device consists of a camera, projector, and coloured finger tips that allow the attached computer to locate his fingers in 3D space. On top of this $350 hardware platform lies a bunch of really cool software that is capable of some really neat tricks. This presentation put my jaw on the floor. Check it out.

The Snap, Crackle, and Pop of Windows Vista Audio

September 1st, 2009

In a previous post, I complained that my Windows Vista x64 machine was suffering from audio that popped, clicked, and sounded like it was, for lack of a better term, ‘losing frames.’ At the time, I had looked around the ‘net some, and tried a few different drivers for my on-board sound card. The problem seemed to get better for awhile, but steadily worsened again to the point where I considered purchasing a new sound card, something that I haven’t done since 1998.

Tonight I took a deeper look down the tubes, and found this forum post that seemed to suggest that the problem was actually with the way nVidia’s 8800GT drivers access system memory when the Vista machine in question is host to more than 2GB of RAM. Following the suggestions in the thread, I headed over to the nVidia website and picked up the latest copy of their drivers (March 2009).

After the installation and a reboot, everything seems to be working just fine, with perfectly clear audio from multiple applications, and none of the annoying popping and clicking sounds that were driving me crazy before.
