When members of my family come to visit, we usually take a drive to Alachua Sink / La Chua Trail to look at the alligators. Notice something in the background?



Here is a closeup:




The water level was really low which tends to concentrate the gators in these few lake areas.

A rather sizable tree frog on our house:

Here is a picture of some of my work buddies (the museum IT department) from a few months ago, taken at a local restaurant named Buddha Belly.

I still had one other nagging problem trying to run the latest version of CentOS Linux on my Dell Inspiron 8100, which includes a Pentium III Mobile CPU capable of SpeedStep. The keyboard and mouse were very jerky. In fact, I would lose actual keystrokes. It's very annoying to type a sentence and lose half of the words. Even very old computers usually do not lose keystrokes, and although they might lag behind a bit, the keystrokes eventually come out of the input buffer. This was a real problem for me since I am a reasonably fast typist.

The issue occured whether or not I was connected to power or running off the battery.

I tried a number of suggestions (such as disabling ACPI by specifying a boot time kernel option) but nothing seemed to work.

Finally, with CentOS 5 installed, I found the solution... turn off the actual daemon that attempts to throttle the CPU speed.

# service cpuspeed stop
# chkconfig cpuspeed off

I'm sure this will affect my battery life, but this laptop doesn't get particularly good battery life anyway and I am usually plugged into a wall outlet. It is possible that the cpuspeed config file (/etc/sysconfig/cpuspeed) could be tweaked to solve the input problem but I did not bother researching this further.

I recently installed CentOS 5 on my older Dell Insipron 8100. For wireless, I use a RangeLAN DS card (in Linux, this card uses the orinoco_cs driver and usually shows up as eth1). In previous versions of CentOS I had to manually identify the card by editing the wifi config files and possibly some other magic. CentOS 5 identifies this card just fine but does not function without a little bit of system tweaking. It seems that another kernel module named hostap_cs conflicts with the orinoco_cs module. I noticed that the status light on the PCMCIA card would continue to flash, instead of coming on solid when the card found the AP.

The fix is to blacklist the conflicting hostap_cs module so the system does not try to load it.

Edit this file:

/etc/modprobe.d/blacklist-compat

Add these lines and reboot:

# hostap_cs conflicts with orinoco_cs driver.
blacklist hostap_cs


Labeling on the Proxim card itself:

I purchased for $15 from Geeks.com a few years ago (I'm fond of geeks.com for slightly older and cheaper computing gear).

Sometime last year, I removed Microsoft Windows from my home computer and installed Ubuntu Linux. It was a tough decision, because I knew I would not be able to play 3D games like Counter Strike Source. I finally found a free multi-player 1st person shooter that is similar to CSS, fun to play, and performs just fine on my not-so-new computer (Athlon XP 2800+ with GeForce 4 Ti 4200). The game is named Urban Terror and is based on the Quake3 engine. Downloads are available for Linux, Mac, and Windows. Did I mention that it is free?
