I’ve been wanting something to visualize mysql slave delay. Looks like LordElph has gone ahead and wrote something already to do it. Cool beans.

Rereading a disk partition table in Linux without rebooting

Ran into a problem with trying to partition up a disk on a running system. The idea is I wanted to create a new partition on a disk with partitions already mounted and use it without rebooting. Here’s what you’ll mostly likely run into… # sudo fdisk /dev/sda … Steps for adding disk elided … […]

Getting screwed by an upgrade (libtidy in Ubuntu 8.04 not ready for real work)

On my workstation at work I’ve been running Ubuntu 8.04 to test out something I’ll post on later. However, one thing that was driving me nuts was that tidy was blowing up with a very unhelpful message like so: /usr/lib/ruby/1.8/tidy/tidybuf.rb:39: [BUG] Segmentation fault At first I thought it was some incompatibility with the gem installed […]

DistroWatch reviews the current state of OpenSolaris on the desktop

DistroWatch has a very good article summarizing the state of running OpenSolaris on the desktop at the moment. Personally, I’m interested in Solaris technology seeing more widespread usage although am not a gigantic follower at the moment. For me the most interesting part was their discussion on what is happening with Nexenta, a project to […]

The Gentoo Wiki to the rescue again. I’m sure you can find lots of other examples as well if you Google around.

How to play mplayer in the desktop fullscreen on Ubuntu

I was experimenting with trying to play videos in the desktop background so I can work on other things while passively watching videos that I really didn’t want to spend 100% of my concentration on. However when I tried to use mplayers -rootwin option under Ubuntu it did not show anything. After doing some Googling […]

Vmware server busting under Ubuntu 8.04 Hardy Heron

One of the joys of living on the edge of Linux releases is the fun of dependency hell. At present, vmware server does not run on the latest released kernel 2.6.24. Which means if you NEED vmware server, you’re screwed. At least until the folks at vmware update vmware server to work with the latest […]

One reason I’m glad I don’t own an OLPC

Hackzine has a blog post on using a SD card as swap space for the OLPC to handle the following situation: Most of the time, the 256MB in the XO Laptop is sufficient. But I use yum to install software, and it can be very memory hungry. I often run out of RAM when installing […]

KDE4 pretty but a bit rough on usability

I’ve been playing with KDE4 on my desktop at home. One of the things I have always liked about KDE is the myriad of options you can drown in while trying to configure something. However, it seems that KDE4 at present is still not up to that task… ah well. Live and learn, I guess.

Voice Chat for Second Life Linux client still not working

This past Saturday I tried checking out the Second Life version of the November TLUG Meeting due to some previous obligations barring me from attending in person. So I went through the rigmarole of installing Second Life on my Linux machine at home and getting it configured to work properly with these things called SLurls […]

Fix the ‘missing key: categories: Cannot read the portsdb!’ for portupgrade

I ran into this exact problem when trying to upgrade a bunch of ports lying around on my FreeBSD system. Luckily Well-Rounded documents the fix for this. You’ll have to upgrade portupgrade manually to rebuild its database with an updated version.

Linux and the MSI-7265, the final straw

I’ve written before before on my battles with Linux and Core 2 Duos. After waiting a long time for Feisty to get closer to a release state I loaded up Feisty (after some initial install pains. The alternate install CD recognizes enough to install but the desktop version doesn’t and requires a USB CD-ROM or […]

Finally a gem release of ruby-opengl

Just wanted to let folks know that I’ve finally figured out how to get the build system in place for ruby-opengl to: Gemify itself Build native extensions during Gem installation using mkrf Which means (I hope) that there should be an easier way to get OpenGL working with Ruby. Currently it should support installing in […]
