Some csua ppl are going email paolo for details \_ Que'est Fugazi? \_ the extremely lame band formed after Minor Threat broke up. Minor Threat was one of the greatest american hardcore bands ever, and fugazi is just another whiny alternative band. \_ who are you, so I can hurl shit at you? Sleater-Kinney plus the invisible scratch pickles are playing too. AND ITS NOT GOLDEN GATE PARK. Dolores Park. - danh \_ rent Donnie Brasco \_ lettuce not forget dj disk and buckethead```
 2000/6/2-3 [Computer/Theory] UID:18385 Activity:high ```6/1 Prove that gaussian is the only function family closed under convolution. ie, forall f,g in H, exists d in H st d=conv(f,g) ===> H is gaussian family. \_ The difficulty of the problem hinges on the definition of 'function family.' I could, for instance, come up with many 'function families' of one element each for which the above would hold. \_ The difficulty does not hinge on the definition of the function family in the trivial way you suggest; it is deeper. There exist uncountable sets of functions H such that for all f,g in H, f * g is always in H. One example of such a family is the set of sinc functions A sinc (w x) with w in [1 2] and A being any real number. This was what I was trying to point out below. -emin \_ Right. The definition could be made too narrow (to make closure easy), or too wide (for instance by making H the set of all continuous functions on R), which would also make closure easy. The point, in both cases, is that we are missing the definition of what a function family is. My guess is that a function family is a set of functions with the same finitely expressible closed form (finitely expressible to avoid the fact that continuous functions on R all have Taylor expansions). \_ Utter nonsense about complete set of real functions deleted. Take a math course, for crying outloud. -- motd math censor. \_ fuck you. \_ This isn't true. Let f(x) = g(x) = sinc(x), then f * g = f. Also, if you let f and g be generalized functions then f(x) = delta(x) = g(x) results in f * g = f = g. I belive what you are thinking of is that if you restrict f and g to be probability density functions then Gaussians are the only pdfs closed under convolution. Not sure how to prove this off the top of my head. Please let me know, when you find out. -emin \_ Depending on the minutia of the formal definition of PDF, a delta function may be considered a PDF as well (since the integral is defined to be 1....). Then, of course, delta can also be considered a Gaussian with 0 st dev. \_ yeah, sorry i meant pdf. i'm aware of the delta function case, but i guess i'd like to define "in the set of" as "approaches an element in the set H, in some sense". also, i think the proof i have in mind requires L2, which deltas aren't. so my proof was going to look something like: since it's a PDF, it must be the square of some other function. look at the fourier transform of the square of something, and realize that it must be closed under multiplication in the fourier domain. assuming that the function is in L2, that constrains it to a large class of functions, which includes boxes and exponential functions. then i was going to use the fact that this is the fourier of a SQUARE of a something to show that within the exponential function, it must be gaussian. i don't know yet how to get rid of the other families that are closed under multiplication. -ali \_ man, do you always have a comment on everything, mr. fricking i know everything about anything? -- alum who dislikes you intensely \_ Disliking ability in others is the only form of evil I know. -- Ayn Rand #1 fan \_ having ability is one thing, discussing topics like this here is another...go to some math newsgroup, don't clog the motd with this extraneous garbage. \_ Oh bull-fucking-shit. Any kind of math discussion is vastly better than most motd discussions, and you know it. It's no crime to be stupid, but it's a shame to be bitter too. \_ The motd has helped me out a lot. Consequently I feel a responsibility to give back and try to help answer questions which I have a clue about. I'm not trying to show off. If you have a suggestion how I can try and contribute to the motd without offending you, please let me know. -emin \_ i don't think "alum" was referring to you. you typically provide the kind of insight the rest of the CSUA is completely incapable of providing. -ali. \_ i'm talking about ali, not you emin. \_ you stupid shithead. i'm the one who asked the initial question. if you have a problem, feel free to post your own moronic "how do i make text bold using html" questions. -ali \_ 'Take your math elsewhere' stupidity deleted, due to its inherent idiocy. -- motd math censor.```
 2000/6/2-4 [Transportation/Bicycle] UID:18386 Activity:high ```6/1 For those who have never biked in a city, any advice? \_ Read "Effective Cycling", by John Forester. Ride on the right side of the road, don't ride on the sidewalk, ride far enough away from parked cars that an opening door won't get you. -tom \_ Which means riding in the street. How's your medical insurance? Linux is safer. \_ two things: riding in the street is safer than riding on the sidewalk, and riding in the street on a bike is safer than driving. How's *your* medical insurance? -tom \_ Stop with the bogus statistics. We're all smart enough to twist the numbers to say anything we want. At least come up with a URL so your numbers can be torn apart fair and square. \_ http://www.kenkifer.com/bikepages/health/risks.htm http://www.magma.ca/~ocbc/comparat.html -tom \_ The first link is full of crap statistics carefully chosen to make biking look "6 times safer than living!" The article makes the claim that if you were immune to all other forms of death and cycled 24x7 you'd live 6 times longer. Uhm, what? What a crock. The second link is just a reprint of the exact same numbers from the exact same people on a chart that was already in the first link. Use Linux. I'm pretty sure it's safer than riding your bike in the middle of the street. Since there are no Linux vs. Biking Safety bogus 'studies' out yet, I can't 'prove' it though the same way you tried. \_ I won't defend statistics coming from impartial studies from the flames of an anonymous coward. I only ask, where are *your* statistics? -tom \_ No study is impartial. Someone paid them to do it. Nothing is free. Your typical ad hominen attack is sooooooo old, tom. Let it go. \_ I think it's funny that I completely smashed tom's totally biased statistics "biking is safer" nonsense and it all got deleted but all the pro-bike garbage was left behind. The truth hurts so some baby has to delete it. No, I'm not saying tom deleted it, but whoever did is a big cry baby biker. I have a \_ I'm not denying the health gain from this or any other form of excercise. The stats tom provided are twisted beyond the point of meaningless, however. copy but won't bother restoring it. I successfully made my point if someone felt the need to selectively purge it. Once again, the biker crowd proves to have the whiney baby bad apples. Biking is *not* proven safer. Certainly not "6 times safer than living!". Time to graduate and join the adult world, kids. \_ The presentation of the stats is clearly partisan. I also disagree with the use of time over mileage, since you spend more time to get there on a bike. Since it is based on all cagers and cyclists, I don't think you can claim either to be safer. the health gain, otoh, is inrefutable. -jor \_ I don't need contradictory stats. I'm more than satisfied to have proved my original point, namely that you don't have any valid stats to back up your false claim that biking is safer than driving. Thanks. I'm done with this thread. \_ per-exposure-hour is pretty much the accepted method for risk assessment. If you cycle rather than drive, you won't commute to Sunnyvale from Berkeley. In a given time frame (or lifetime), exposure hours for a cyclist and driver will be similar, even though exposure miles will not be. Exposure-hours is clearly a better measure if you are interested in how likely it is that you personally will be affected. I agree that the presentation of the stats is partisan--that's because it's a cyclist's site. But I challenge you to find contradictory stats of any kind. -tom \_ be careful, especially in berkeley...almost got sideswiped by an ac transit bus. \_ Doesn't matter if your on bike or in car, ac transit drivers don't give a shit and figure it's your job to get out of their way. \_ ...and thats probably the least that you can do. If I drove a 30 foot bus around for 8 hours a day, I'd probably be somehwat pissed too. \_ A friend of mine fell to avoid a pedestrian on campus and broke his PalmV. Make sure you carry it in a hard case and not a leather one if you bike a lot. \_ One friend of mine had a bad fall. Mostly burns but he was in such pain I have to go pick him up. My old roommate got it worse - concussion, loss of consciousness, broken jaw, bike disappeared, overnight stay at ICU, loss of maybe 3 week worth of memory, huge medical bill, one lost semester. \_ Must've been the fault of the car. \_ Who knows. I also biked to school everyday in Berkeley. poor college students. It is very dangerous (heard of other incidents too), so becareful. Also, be very careful with bike thieves. A good bike is almost gauranteed to be stolen unless you are extremely careful with it. \_ You need a Denver Boot for your bike. \_ Who knows? *Obviously* it was the car's fault. The guy on the bike is *always* an Innocent Victim of the Evil Motorist. Bikers *never* do any sort of "creative" non-following of the laws. Never happens. \_ very simple piece of advice that you will pick up fast. STAY OFF THE MAIN DRAGS. Biking down, say, Sacramento, is foolish. Just go a block off the main streets and creativly pay attention to traffic laws. \_ But who would be the first to bitch and moan and piss and whine if cars were half as creative with the laws as bikes? When they require a license to ride a bike in traffic, I'll take bikes seriously. Until then, it's for kids, AIDS rides, and poor college students. [Restored the truth for you big baby biker types who can't deal honestly with life] \_ exactly! stay off the min streets. especially shattuck to avoid those ac transit buses unless you have a death wish. \_ Sacramento is a fine cycling street. Telegraph is the best commute street in Berkeley. Side streets have bad intersections--most bike/car accidents happen at intersections. Riding, for example, on Colby/Hillegass is much more dangerous than either Telegraph or College. -tom \_ I used to bike up and down San Pablo Ave, especially if it was busy. The only naer collisions I had with cars were ones that sped through side streets. \_ Yeah, ride 24x7 and you'll live 6 times longer according to tom's bike safty statistics.```
 2000/6/2 [Computer/SW/Unix] UID:18387 Activity:high ```6/1 it's fucking summer man, go outside and get off the MOTD! \_ yeah, it's fucking hot too. still brings back memories of what was the number...199 cory with those awful green vt100 terminals and the sweltering heat. \_ e260 and a room full of diskless sun 3/50s! \_ Oh, man I *dreamed* of getting to use e260. I was stuck in the WEB (back when it meant something different).... \_ idiot. \_ Meant what? \_ "Workstations in Evans Basement". I *hate* \_ "Workstations in Evans Basement". BTW I *hate* those 3/50 keyboards. The Sparc ones are much better. (Of course the tvi920c ones are even worse, but we're not stuck with those.) -- yuen \_ Uh, I know what WEB meant. You were implying pre-sun 3/50s in the WEB. e260 had the same 3/50's and file servers as the WEB. It was the same cluster split over two physical locations. \_ I know. I wasn't the one who said dreaming of e260 and stuck in the web ... -- yuen NFS Server widow not responding... NFS Server widow ok. \_ Yes! I had forgotten how much fun that message was! How nostalgic! Except you need the "not responding" line about 15 more times.```
 2000/6/2 [Computer/Theory] UID:18388 Activity:high ```6/1 Dinosaurs and antigravity: http://www.bearfabrique.org/sauropods/biganims.html \_ it was once "proven" that you would suffocate if you moved faster than 20 miles per hour. What a load of crap. \_ /. \_ It's \. not /. -- bill gates \_ Yeah, but read it. It proves that at one time the earth's gravitational pull was much lower. \_ No it doesn't. Read the responses in /. and you'll see refutation of the numbers. \_ Not surprisingly, slashdotters are wrong. Bad math. \_ I can't find anything on http://slashdot.org searching for dinasour. However it seems highly unlikely that they would screw up the trivial math. It is not the math that is problematic but the underlying assumptions. \_ maybe that's because its spelled DINOSAUR! \_ Maybe the atmosphere was richer in oxygen such that muscles could grow much stronger and withstand a much higher force- per-unit-area than those in modern animals. Maybe the winds blew much stronger than nowadays such that a glider could take off easily. Just some idea. -- yuen \_ Wind might help the flyers but doesn't help a 70+ ton beast stand up. I don't know enough anatomy/biology to say anything about your oxygen theory. Where's a bio- dynamics major when you need one?```
 2000/6/2 [Computer/SW/Compilers] UID:18389 Activity:moderate ```6/1 Is g++ (gcc) installed anywhere other than /usr/bin/g++? Any newer version than 2.7.2.1? (locate didn't help) \_ So, get yourself added to the contrib group and install gcc-2.95.2 (or whatever is the lastest version). \_ They weren't whining that it wasn't installed. They were asking if it was installed. \_ It might help if you actually read the question, fuckwit.```
 2000/6/2 [Recreation/Food] UID:18390 Activity:nil ```6/1 I went to In&Out Burgers for the first time. Man, I don't know what the hell people are bragging about. \_ the burgers are tasty...not like that salty shit you buy from mcDonald's. firmer than the whopper, which is more akin to a sloppy joe. still, barney's rules tops, esp. the turkish coffee milkshake and spicy curly fries. kiss your low cholesterol level goodbye... Oscar's? shit food for a shit price, I could make better stuff at home. \_ Their fries are the bomb. Burgers are a step up from McDonald's & Burger King, but not up to par with Barney's. \_ The bomb? You're watching too much black trash on Jerry Springer. \_ the fries are disgusting. The burgers are prety good if you like that kinda burger, but I'd rather go to oscars. \_ their fries are the absolute worst. Their burgers are passable. It's mostly just faux nostalgia. -tom \_ Well, I love their fries. The only fries that I've had better were Boardwalk Fries, which used to be in Valley Fair. Sadly, it's gone :( \_ the fries are limp and often taste like they've been fried in fish oil. Yuk! \_ The fries are unique in that they MUST be eaten hot. They go from being the best fries to being the worst if you let them sit and cool down. So this basically means you have to finish your fries before even thinking about starting your burger. \_ that's not unique in these days of starch-sprayed fries \_ Order the double-double animal style. mmmm..... \_ Not as good as having it 10 by 10 animal style! Oh yeah! And yes, I must say the fries are crappy... not very crispy \_ order your fries well-done. mm, like potato chips! --oj \_ You get your lovely Bible reference at the bottom of your cup (at least for shakes and for cokes). Gotta love the fundementalist Christian wackos putting their religion down your throat, literally! \_Yeah, but you only get "John 3:16." Like a scratch-and-win, I always look to see what I got each time ... only to find out I'm a loser for having faith in organized religion! \_ This only goes to show that the people you know have no taste. To say something is better than McDonald's is quite similar to saying it is better than garbage from my compost heap. \_ What would you compare In & Out to then? I'm comparing it to its competition, which is fast food joints. \_ I would have the good sense not to eat at McDonald's, In & Out or any competitor. My compost heap tastes better than your compost heap. Is it important that my heap is tastier than yours? Think about it. \_ sometimes in the issue of time, fine dining is not an option... \_ sometimes in the issue of time, showering is not an option either. just tour 2nd floor soda.```
 2000/6/2-3 [Computer/SW/OS/Windows, Computer/SW/Unix/WindowManager] UID:18391 Activity:moderate ```6/2 I'm looking for open source unix ware to create a web based email archiving service. It should allow people to sign up/remove remove themselves and have a threaded message archive. Some sense of user levels would be nice, too, like anonymous people can only read the archive, but 'registered' people can do whatever, and an admin level who can delete messages. The number of registered users is going to be under 20 and never grow above 20 or so. Performance isn't a big issue. This is a personal project. Thanks for any pointers! \_ you seem to be describing a web based newsgroup like slashdot more than you are a web based email service. if that's the case just go to http://slashdot.org. they have their entire source code (called slash) published online under gpl. http://www.slashdot.org/code.shtml \_ I want archives based on incoming mail. The web interface is only for reading old email archives in threaded format. I don't want slashdot. Email comes in to some majordomo like handler, gets archived on the web pages, and gets sent out to the correct list of folks on the list. If there's a web interface to archived majordomo email that would probably do the trick. \_ Do you mean something like hypermail? \_ I might. Got a URL? Thanks! \_ http://www.landfield.com/hypermail```
