Smoke Testing Kernel 2.6.15

Kernel 2.6.15 became available January 3rd. I downloaded it and did the build and install dance to test it out on my Gateway under SuSE 10. What follows are my initial impressions.
  • Overall quality appears to be very good. It was built using gcc 4.0.2. I use Grub because it's very simple to add a new kernel to /boot and then to edit /boot/grub/menu.lst and add a new stanza for the new kernel. What is interesting is that the 'pci=noacpi' boot property for kernel 2.6.13-15.7 (the SuSE kernel) is no longer needed. I know that the boot property is needed for the stock 2.6.13 kernel as well as 2.6.14 kernel on the Gateway.
  • In spite of what I've read, you have to build and install both Broadcom drivers (Tigon3 and NetXtremeII). If you only install the NetXtremeII driver then Broadcom networking will not come up (Device Drivers > Network device support > Ethernet (1000 Mbit)).
  • The Intel PRO/Wireless 2200BG support is in the kernel and appears to at least start up. The problem is that the driver has been compiled with version 19 of the wireless extensions. The wireless tools that ship and install with SuSE 10 only support up to version 18. This means that if I want to turn on wireless when I boot via the Gnome applet or to successfully manipulate the wireless interface with iwconfig, then I'll need to find and upgrade to the current set of tools. Also, a note to the first time kernel configurer: You have to enable Networking > Generic IEEE 802.11 Networking Stack before you will see an entry for the Intel chip under Device Drivers > Network device support > Wireless Lan.
  • I use a Logitech 4000 Pro webcam. The driver that comes out-of-the-kernel does not work, so I have to always go and download the Phillips USB Webcam Driver from I've done it for kernels 2.6.13 and 2.6.14, and it continues on for 2.6.15.
  • ATI 3D hardware acceleration is broken. An attempt to use my current ATI driver to work with this kernel results in a 'Unknown symbol verify_area' message when I attempt to load the module. This means downloading and installing the latest ATI driver which I believe corrects this problem.
So far everything else works fine. The problems I've touched on are more interesting than annoying, and are to be expected when you go and tinker with the kernel. More importantly they give me a heads up for the future time when I will most likely upgrade from SuSE 10 to SuSE 10.1.

A Decade Long Religious Con Job

I rarely write inflammatory (what some might call trolling) titles to a post, but this building you see before you deserves it. I've been seeing this building next to I-4 just east of Altamonte/436 and Crane's Roost for nearly 12 years, and never knew who owned it. Today on a trip up to Lake Mary with my wife I saw it yet again. That's when I told her I wanted to stop by on the way back and poke around the property, and photograph any parts of it if I could.

What I discovered was this still unfinished eighteen story (I counted) white elephant, overgrown with weeds and yet still under slow-motion construction. It looks impressive with its exterior glass curtain walls, but that impression is quickly lost when you see the unfinished lower stories and look inside to the unfinished interior spaces.

A quick check via Google leads to an article written in 2010 by the Orlando Sentinel about the Majesty Tower. Based on what I read in the article it's owned by SuperChannel 55 WA…

Be Careful of Capital One Mailings

Capitol One ("What's in your wallet?") sent me a bit of deceptive snail mail today. I felt sure it was a credit card offer, and sure enough, it was. I open all credit card offers and shred them before putting them in the trash. Normally I just scan the front to make sure I don't miss anything; the Capital One offer made me stop for a moment and strike a bit of fear into my heart.

The letter's opening sentence read:
Our records as of December 30, 2009 indicate your Capital One Platinum MasterCard offer is currently valid and active.Not paying close attention during the first reading, I quickly developed this irrational worry that I was actually on the hook for something important, but I wasn't quite sure what. The letter listed "three ways to reply" at the bottom; via phone, the internet, and regular snail mail. I elected to call.

Once I reached the automated phone response system, the first entry offered was '1', to "activate my Capital …

cat-in-a-box channels greta garbo

So I'm sitting at my computer, when I start to notice a racket in back. I ignore it for a while until I hear a load "thump!", as if something had been dropped on the floor, followed by a lot of loud rattling. I turn around and see Lucy in the box just having a grand old time, rolling around and rattling that box a good one. I grab the GX1 and snap a few shots before she notices me and the camera, then leaps out and back into her chair (which used to be my chair before she decided it was her chair).

Just like caring for Katie my black Lab taught me about dogs, caring for Lucy is teaching me about cats. She finds me fascinating, as I do her. And she expresses great affection and love toward me without coaxing. I try to return the affection and love, but she is a cat, and she takes a bat at me on occasion, although I think that's just her being playful. She always has her claws in when she does that.

She sits next to me during the evening in her chair while I sit in mi…
