6/2 This Sunday, Fugazi @ golden gate park. 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.

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.

initial question. if you have a problem, feel
free to post your own moronic "how do i make
text bold using html" questions. -ali

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. |

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)....

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.

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? |

\_ So, get yourself added to the contrib group and install gcc-2.95.2
(or whatever is the lastest version).

asking if it was installed.

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

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!
