Linear Algebra
"A" is for Algebra, and that's good enough for me!
That's no metaphor. After 5 1/2 hours of sleep I got up at 6am Friday to drive to Baltimore and run a fencing camp all day. I got home around 9pm, drank a beer, and started the final steps in upgrading to a new server (the very machine this website is hosted on). At 5:30am, after a long night of fiddling, cursing, disassembling and reassembling, I bagged it and went to bed. Less than 5 hours later I woke up again, made a light breakfast and got back to work. And, finally, Eureka! It works!
Now, if I can only get a little more sleep...
I spent a lot of time today (Wednesday) installing better spam filtering on my server. What a pain in the ass. Now I have pretty agressive policies in my sendmail, the very latest version of sendmail, a greylist, and as before baysian filtering. Still getting too much spam!
The Washington Post reports on Alexandria's new effort.
Alexandria VA is right alongside London England when it comes to providing free outdoor wireless internet. This will change the way I get ready for my Monday night practices there.
So today I played Gran Turismo 4 some more. I had finally gotten a car capable of winning the last championship in Professional Events: an '01 Audi R8 Racecar. It doesn't have as high a power/weight ratio as the '88 Jaguar XJR-9 Racecar but overall it's way easier and faster to drive.
So I win all the races in the championship series except Hong Kong, and none of them was easy. I can finally savor the prize which is only unlocked after winning that series: Extreme Events. I go there, and it turns out there's a whole new license you need to earn before you can enter most of them: the S license. Geez-us! So I work my way through them one at a time, and none of them is easy. Only two or three of the 15 do I pass on the first try, and only one do I get better than a bronze. Then I get to the last of the 15 tests: One lap of Nürburgring Nordschleife. This track is insane enough with the normal lax rules of the game, but in testing mode you can't let all 4 wheels get into the grass or BZZZT! Try again!
On my second try I get 99% of the way around, breathe a sigh of relief, and drive off the track. G%*&S!S*&#@$IT! So I work at it a bit more, feeling frustrated. I eat lunch. Try some more. Turn off the lights so I can see the track better. Try some more. Hang a dark sheet over the window so I can see the track better. Try some more. Make some tea. Try some more. Eat some chocolate. Try some more. I'm literally sweating from the effort of trying to navigate this 22.8km circuit.
Eventually I do finish the circuit, 20 seconds faster than necessary to pass the test. Geeze. Maybe if I just slowed down and finished the damn thing I could have saved myself 3 hours...


My Linear Algebra prof gave us an extra credit option: watch the movie Sneakers and write a report on it. I just finished watching it, and it's cute and shows basic snooping techniques, but it doesn't appear to have anything to do with Linear Algebra other than an empty passing reference to homomorphism. Lame, I tell you. Kill me if I ever become a mathematics professor.

I took my first Linear Algebra quiz on Tuesday, and got the grade back Thursday: 100% !!!
I'm going to Northern Virginia Community College, taking one course in the summer. I hope (according to one possible future) to get back into George Mason University next year, after taking classes at the community college thus summer and fall, and perhaps the spring depending on how stringent GMU is.
It's been 13 years since my previous quiz in a college course. During the interval I drove my car into a tree, stopped going to quizzes, was dismissed, rode my bicycle to temp jobs, got a salaried job, learned a lot about writing software, found a hobby, made a lot of money, got laid off, turned my hobby into an obsession, spent all of my money and more on it, found a new job, got laid off, learned a lot about fencing, competed in the world championships, ran out of scratch, got old, turned bald, started teaching people to fence, filed chapter 7 bankruptcy, and went back to college. Voila, my whole life in one sentence!
Now I'm a fencing coach going to community college. I have a good handful of students, but I need about twice as many to really pay the bills. Eating pasta gets old real fast. What gets old even faster is having the IRS put a levy on your checking account.
So I need to develop some marketing skills, to grow my fencing business. And I need to keep on getting those 100% grades, so GMU will allow me to spend my money there next year.
