The UN inspectors have found a dozen warheads usable for chemical weapons. In my opinion, the Iraqi excuse sounds fishy. If Bush bombed Iraq tomorrow morning, I'd feel a little bit less strong when I walked onto the I-5 freeway, but it wouldn't stop me nor a few hundred students. This evidence is bad news for anyone who wants to see peace in the Middle East. If Iraq is forgetful enough to leave a dozen empty, unusable chemical warheads in plain view, what else have they forgotten? Oh, we forgot to get rid of this thousand tons of Agent Orange that we bought surplus from the US in 1989. Doh! I think it's time for Iraqi military to get their arses in gear and double-check those weapons for stray strains of botulism. It reminds me of a song by the Canadian band, Three Dead Trollies whose humorous music is on mp3.com. Put away the dead hookers, used syringes, sex toys, and weapons of mass destruction, Iraq, momma's coming for a visit!

If my humor doesn't please you, you're free to go find some humor elsewhere. But no more humor from me. This picture is a less horrific version of last night's "airbrush nightmare". How did I make it "nicer"? I reduced the number of triangles by a huge number. It used to be 2*(2^8)*(2^8)=2^17=131072 triangles. It rendered at about 120 fps solid. Tonight, I turned it down to a sane 2*(2^3)*(2^3)=2^7=128 triangles. It renders at a very jerky 60-90 fps. Rendering the original 131072 triangles gives me a stable 12 fps. Why? Because I am using MilkShape file format/objects (indexed triangles) instead of my own file format/objects (indexed triangle strips). So I switch formats and the fps go down to 12 fps, a factor of ten. Why would I use the Milkshape format? Two reasons, the first is simply because I want to be able to control things. I can't control things with indexed triangle strips. I am working on that lossy level of detail algorhythm (almost done) and it requires indexed triangles. The second is that I want to save my terrain file to MilkShape3D file format so that I can edit the file in MilkShape3D model editor. I don't have the skill or patience to make a model editor that can replace MilkShape, so I'm simply going to use MilkShape. And MilkShape is really good. Anyone who wants more than MilkShape is a stuck-up artist type that you don't want to become. Inverse Kinematics and Bezier splines are for people who have more money than you do. While the free GMax editor boasts this, it certainly does not deliver like MilkShape. I gotta get back to my work, but I hope to send you off with a little tidbit of a lesson.

If you are new to Linux and you installed it yourself, you might notice that it's far slower than Windows when loading files from hard disk or copying them from CD-ROM to hard disk. This is not because Linux is slower. It is because someone forgot to write some automatic tools to speed it up. Well, that's what I'm going to give you. The trick is a program called hdparm. It enables DMA, Ultra-ATA/33/66/100, advanced power management, and unmasking irqs. What that means is that you'll get a factor of 5 increase on your hard drive and CD-ROM speeds. That's right! That's exactly what I got and I haven't been so happy for a while. While you should search the net for a command that suits your hard drive, and test it thoroughly before putting it in your /etc/rc.d/rc.M, the command line I use is: hdparm -m0 -c1 -u1 -d1 /dev/hda hdparm -c1 -u1 -d1 /dev/cdrom What it means is to disable multicont, enable 32-bit I/O, enable irq unmasking, and enable DMA. DMA cuts cpu usage by about 500% during loading. 32-bit I/O doubles the speed by taking twice as much data. Unmasking the IRQ is just better since it allows you to recieve interrupts while waiting for the hard drive interrupt. Something I found wonderful was this command: hdparm -y /dev/hdb This puts my second hard drive on standby. This is a low power mode so that I can have my two hard drives connected, but only use the second one when I need it (very rare, since it's my 6 GB Windows98 hard drive). Now that is something that Windows cannot do out of the box: shut down a hard drive. I hope you use hdparm and I hope your experience with Linux is as positive as mine.
