 1998/12/3-4 [Computer/Theory] UID:15060 Activity:high ```12/2 I'd like to take Computer Vision CS280 next year. However, it requires math 53/54. What's the difference between 53 and 54? Thanks. \_ 53: Multivariable calculus - integrating over multiple variables surface integrals, cool looking 3D pictures 54: Linear Algebra but not in the sense that is useful from any kind of computer graphics work. The only thing you need \_ yo: graphics != vision. I took 280 with malik in 1994. grrrreat class!!! -nick to know for, say 184/284, is transformations/translation stuff. differential equations are also covered which is not fun at all. DiffEq is used a lot in EE and E&M (especially EE120) but chances are you're not going to have to know what a Wronskian is. I still don't know but those jack ass math profs (referring to Miller of course) think that all this is really important. The basic fact: only about 5% of what you learn in Berkeley math classes will become applicable to you in the future. \_ I'd be curious to know whose orifice you pulled this statistic out of. i use what i learned in berkeley every day. i have been thankful of having learned at least 90% of it at one point or another. you are an idiot if you don't think knowing diff eqs is important. are you satisfied knowing only how to solve diffeqs with constant coeffs? that solve 80% of the problems you will run into as an EE, but that's about it. or are you just satisifed not knowing how to solve diff eqs at all? you think you've been doing fine without them, but the truth is, people in Bangladesh probably think that their lives are just fine too. here's what you need from linear algebra for cs280: bases, transformations, least squares, rank, singularity, eigenvectors and eigenvalues, orthogonal, orthonormal. That's basically all of the Anton book. -ali \_ I never use any math beyond some very basic algebra. I use *none* of the math I learned at Berkeley. This pleases me more than you can imagine. \_ Actually, math beyond basic algebra can be pretty useful (especially some calc used in physics, electrical, engineering, and some other science classes). But the difference between the way a high school teaches and a college does is that in high school they teach you how to solve practical problems whereas in berkeley they're so caught up in theoretical proofs that only math majors really care about. \_ I'm not denying it. I'm just glad I'm not in a position to need any of it. I'm not even using HS math. More like Jr. High. Suits me just fine. YMMV. \_ well, good for you. but honestly, 90% is frikin insane. Maybe you had a better prof than I did but I never had to implement the things I learned from math 54 in any physics 7 or EE classes to the extent that you brag about. I admit having to solve simple diff eq's and integrate relatively simple equations but I never had to do boundry equations, prove the so called "Keith Miller's Equivelance Theorem", find eigen vectors, and do most of that math 54 crap. I'd like to know whose orfice you're pulling that BS out of. \_ I dunno, when I took 54 (then called 50B), I actually used what I learned (when I was awake to learn) a week or two lagged in Physics 7B... \_ ali lives on a higher plane. \_ You are all idiots. I use 0% of what I learned in Cal. All I do everyday is to count the money I make and the # of new concubines I get. And I learned how to do that before I was born. College is useless; education is stupid. Ignorance is strength and self-esteem comes from the cavity of an empty head. \_ Take upper division physics, math, chemistry, or astronomy (probably others in engineering, too) and it will make a lot more sense to you. The lower divison math classes are essential to any career in science or engineering (hence, they are required) and really useful in some other fields, too, like economics. --dim \_ You can do just fine if you know math just up to Math 53/54. You can do hot sh*t and make much \$ with insight and initiative; you can also do hot sh*t that wouldn't be possible without sophisticated math knowledge, and make much \$. You may feel fulfilled in either case, depending on who you are. In either case, you will earn the admiration of people who you think are brilliant and people who you think are idiots, and disapproval and disgust from the same range of persons. -jctwu \_ Not really. Remember Ted Kazinski, the brilliant math genius. I don't think anyone liked him. \_ especially the rabbits. -jctwu \_ "Math is hard! Let's go shopping!" -Barbie \_ amen. \_ Was it Barbie or Malibu Stacy? \_ One, last I checked...```
 1998/12/3-4 [Transportation/Car] UID:15061 Activity:high ```12/2 If someone parks a car illegally blocking my driveway after office hours, which govt. dept. do I call to have it towed? Thanks. \_ Post your address here so we can vandalize the car and your home at the same time \_ Tow Truck Company (after using your key of course) \_ Police \_ parking and transportation dept of police \_ But do they work at night? \_ Marine Corp. \_ Goldberg. \_ Just try to get someone to steal the car. \_ Or put a bunch of bumper stickers all over it \_ Those non-profit charities that take donated used cars \_ Which can take a few weeks to get them to come by and requires you fill out paper work, prove ownership, sign papers transfering ownership, etc. Nice try though.```

 1998/12/3-6 [Computer/SW/Languages/Perl] UID:15063 Activity:nil ```12/3 Need perl hacker for a few days to write a preprocessor for an assembler. Contact ali. \_ ali needs to be sodomized```
 1998/12/3-4 [Computer/SW/WWW/Server, Computer/SW/Unix] UID:15064 Activity:moderate ```12/3 According to "man www" if I want to have server side includes on my web page off of csua, I need to either change the file extension to .shtml or make it executable. Is there any reason why I shouldn't just change all my web page file permissions so I can avoid having everything end with .shtml? \_ for files identified as SSI-capable, the web server preprocesses them line by line for every page hit. normal files are served up "straight" without this overhead. --jwang \_ So we're talking about a difference of probably milliseconds per page load here? \_ I've done this on a Linux server. I found differences of several seconds. I never did figure out why the huge difference. \_ the only way there might be that much of a difference is if your WWW server is CPU-bound (extremely unlikely) or you're getting the documents off NFS or something. It should not be a noticable difference. -tom \_ But it is possible. It does depend on what is being interpreted by the SSI. Use .shtml only if necessary. \_ Are you implying it's better to make your file executable then? Or in general, use SSI only if necessary. \_ the latter. -tom```
