more info on gibson and semiotics please!

Anyway, back to getting plastered:
Beer:
Stella, Guinness, Samuel Adams winter packs, Blue Moon

Wine:
The really good cheap stuff from australia. Can't beat the reds.

Liquor:
A good Gin & Tonic is hard to beat. Bombay Sapphire or Hendrick's(damn good, and not too expensive)
Used to be a fan of the Jaeger, until too many bad episodes cause instant gagging(!)
And my new fave: Absinthe. Yeah, really. And the good stuff, most stuff out there is crap. For an interesting and (somewhat) educated discussion of this stuff: http://www.wormwoodsociety.org is the nekochan of absintheurs.
The Jade's are pretty good, planning on picking up a bottle of the Eduoard over new year's.

merry times!

AFAIK, absinthe is legal in canada, but american's should note that while illegal to buy/make/whatnot in the US, it is not illegal to receive a shipment(!). So there are quite a few outfits in the UK and other places in the EU that will ship via courier to the US, and have pretty good service and delivery times. Check the vendors page on the wormwood society's page.

Re: Gibson/semiotics
I suppose I should've been more specific than that. I've read the bridge trilogy and found it nice, if a little tedious. I do that with books, I've been about 3/4 finished with Atlas Shrugged because I can't expect to be surprised by the rest. never even read the DaVinci code because given a few hints by a friend reading it, I knew what the ending was going to be. Bummer. I hate simple movies for the same reason. Anyway, I was looking for more good picks of things to read, by him and in the same vein. And yes, neuromancer was on the list, as was the cryptonomicon.
As for semiotics, it's almost always used in texts where the author is being intentionally obtuse because there really isn't much to say, poor anthropology for one example. I suppose I know a thing or two about it given my dad worked on some sort of international signage program back when the government gave two bits about that kind of thing. And Edward tufte's books have been on my wishlist for years now, that guy's got it down pat! But obviously, more links/resources are greatly encouraged.
Thanks!

scotte, if I were you, I'd still go for it at the gov't auction, you now know what this guy will be bidding up to, more or less, and that's a pretty good deal for an onyx2 rack.

Wrote on the subject of Woot! 100k Seti units! at May 8, 2006, 9:40 p.m...

hey everyone, just a few words re: seti

So I just started seti back up after a long time away(some thousands of classic hours though), and it's running on a few of my computers. I joined team nekochan, so you've probably seen me.

Anyway, the numbers will probably drop again in a few weeks, the big machines are coming home so they won't be getting free juice from the school anymore. May curtail their activity a little. Looking at my stats, it's interesting to note that the Xeon at 3.06Ghz, splitting it's time 50/50 between seti and sdzg, is just about neck-and-neck with the ip27 4x250mhz. I might run the origin with all its 8-procs against the xeon at 100%, if they're equal that's pretty funny.

Crunch on!

well, I doubt they will stop distributing work for the normal boinc seti for some time yet. In the meantime, many people are working on porting enhanced to different platforms, the source tarballs are available. there's always room for help!

Wrote on the subject of quad-precision benchmark at May 17, 2006, 4:57 p.m...

Hi,
This is kind of an outgowth of the debate on R10k/Itanium architecture over in the thread about the 1ghz r16k's. Anyway, I figured i'd make a little benchmark. The code is at the bottom of this post. Anyway, I was wondering if anyone could compile it with MipsPRO and optimize for R10000. I'm getting bummer numbers...although the pentium's technically not doing the same thing. Ok, so two requests:
1) Can someone figure out why the p4 won't do 128bit with long double? Do I have to do it by hand? I thought this was what sse2 was for?
2) Can someone compile test_quad.c with mipspro optimized for r10k?
THANKS!

here's what I got:
nekochan's gcc 3.4.0 vs. gentoo's 3.4.5
O2k on 1 R10k 250

Code: Select all


-bash-2.05b$ gcc -mtune=r8k -o test test_quad.c


-bash-2.05b$ ./test


Using default value, n = 128


size of long double: 16




Elapsed time to multiply two matrices of order 128: 30.121496

And Dell on 1 Xeon 3.06

Code: Select all


logan@chopstick ~ $ gcc -o test -mtune=pentium4 test_quad.c


logan@chopstick ~ $ ./test


Using default value, n = 128


size of long double: 12




Elapsed time to multiply two matrices of order 128: 0.066819

and finally, the code:
test_quad.c

times are in seconds...

I knew I was supposed to do something before getting dinner. Fixed, thanks!
