Serving data with http and ftp is is not very CPU intensive, but over time the amount of rsync traffic being fed by the kernel.org server continued to increase, and rsync is CPU intensive. "That's what rsync does" Peter said, "it trades bandwidth for CPU horsepower...
I don't have occasion to use rsync, and I'm not too familiar with its design, but I think it synchs directories by checksumming the files in them to see if they differ. So Peter is saying above that the server's bottleneck is checksumming. I would think that on a server like this, checksums could be cached - why checksum a stable file more than once? Once you have a checksum for
linux-2.6.0.tar.bz2, why calculate it again?
This would require a bit of bookkeeping when files change, but wouldn't it be worth it on such a busy system? (Or am I confused?)
ya gurps, interesting points. i hack robots, so i am familiar with control systems that tend toward stable or unstable. i wasn't literally saying that we earthlings could protect ourselves from destruction with duct tape, but in general, i figure that the sorts of threats we face on earth are probably more manageable than the threats we face on strange new worlds.
in the v_e_r_y long run, it makes sense to find a strange new world to live on - eventually, our figurative roll of toilet paper will run out. the subtle question is, when does it become wise to pursue that goal? just because it's bound to happen eventually is no reason to start looking now, any more that if i know my car will eventually wear out, that doesn't mean that it's necessarily wise to start shopping for a new one right now.
Las Vegas is a great place to live because it has a breathable earth atmosphere, and you can send water there by laying pipes. (Actually, it seems that Las Vegas was originally settled because of
water.)
You say that "Outer space IS a great place to live." I would say that some where out there in outer space is a great place to live, but the odds of our finding it are infinitessimally and prohibitively small. Human travel is still bound by human scale.
Your point about previous earth-bound disasters having already eliminated all larger life forms from our planet is also biased - those life forms did not have the protection of galoshes, sunscreen, wooly mittens, hepa filters, duct tape, and so forth. I can get that stuff at the corner drug store for less than the cost of a "simple 1,000 person colony on the Moon."
In a theoretical fantasy, I'd love to have the option of living in a galaxy far, far, away. I just don't see at all how it would be practical to do so.
The desires expressed to go away from earth are not practical. What if something happens to ruin earth? You'd have to ruin earth's environment to make it less habitable than your romantic far-off space destination. A couple of atom bombs and a tsunami now and then don't come close to making the mess that is gracious living on the moon or mars or alpha centauri.
If outer space was such a great place to live, people would already be going there and building country homes and golf courses.
Last year's Usenix conference was full of Powerbooks.
People don't carry laptops to hack. They carry them to use apps. What is important is what platform hackers are developing for, not what platform they're using to read mail and surf the web.
When I was growing up in the 60's and 70's, my favorite radio guy was
Jean Shepherd. He had a radio show out of WOR in New York every night, for 45 minutes to an hour (depending on how long they ran news, etc). Shep told stories and was pretty nerdly and generally entertaining, he was an old radio guy, including being a ham and morse code guy. He wrote stories that were published in Playboy and Car and Driver, and in a handful of books.
There is a web
archive
of about a thousand of his shows, all in mp3.
Yes, my math was fuzzy, I was offering an estimate. My math was not wrong. (The "one million" was a silly Austin Powers joke, as I mentioned above.) The actual cost of a raw gig is way less than a dollar (and always falling), and I allowed for the fact that I wasn't even talking about compressed data. I am aware that storing large amounts of data is more than just the cost of the media, but still, the AOL guy implied that it wasn't financially feasible for AOL to store the data, and I'm claiming that for folks who want to snoop on all that data, the costs are definitely not prohibitive.
The biz about Dr. Evil and the "one million dollars" was a sarcastic reference to Austin Powers, who was similarly confused about both modern technology and how much things cost. (Sigh.)
OK, a gig of disk costs a dollar, retail, more or less. 500 gigs, let's see. $500. $183k per year. You think that's a lot of money for AOL? That's like the loaded price of one senior engineer. (And that's before buying the disks in bulk or compressing the data.)
Uberti explained on his Weblog that the amount of IM traffic on the AIM network "is on the order of hundreds of gigabytes a day."
"It would be very costly, and we have no desire to record all IM traffic. We don't do it," Uberti wrote.
Ooh, hundreds of gigabytes a day, it would be very costly to record all that traffic. Gee, Dr. Evil, what does a 100 Gigabyte storage device cost? One Million Dollars?
The light source for the foot shadow is from below and left. The light source for the white text shadow is from above. Wussup widdat? Or is it just me?
I'll echo this question. The PPU sounds like another form of coprocessor - vector processor, graphics processor, etc. I can understand why you'd want one in general, but if you were desigining one, I don't know why you'd limit it to (game) physics.
The UNIX wars go way back before Sun, SGI, Gould et al - by 1985, Unix was already 15 years old and had undergone several rounds of pointless splits, with different groups insisting on not cooperating. Within the Bell System, there was Research Unix, USG Unix, PWB Unix, and Columbus UNIX. AT&T realized that the split was a problem, and developed System III and System V to try to rein it all in. By 1980 or so, BSD (actual Berkeley UNIX developed at UC Berkeley on PDP11's and then VAXes) was in full swing, and the split was between AT&T and UCB. Ian Darwin and Geoff Collyer wrote an
article back then that covers some of this.
Soon the Motorola 68000 was available, and you could run UNIX on a single chip CPU. Now anyone could start a computer company, there were a hundred groups with Unix boxes - Sun, Fortune, Masscomp, Convergent, etc. Still no cooperation. These were fully fledged Unix graphics workstations, with networking and graphics, multi-user, with real process scheduling (slower than today, of course). Imagine how they compared to x86 PCs running windows, and weenie 128k Macs. Of course, there were 100 different kinds and no manufacturer wanted binary compatibility, for fear of losing an upgrade sale to a competitor.
I don't want to go into more detail here, you can read about it on the web. But the cliches about unity all apply. Divide and conquer, united we stand, we must hang together or assuredly we will hang separately etc.
most educational software... are often far to expensive for a working class family.
I can't help you with software suggestions, but if you do decide to steal the software, note that legally you're on much
safer ground
stealing the CD from a store than downloading an illicit copy from a filesharing service.
Yep, the biz about the 68k being used in the "PDP line" of computers a decade before 1983 is clueless. The 68000 came out around 1980. The PDP line wasn't a homogeneous thing anyway, there were PDP-10 mainframes, PDP-11 minis, and PDP-8 smaller/cheaper minis, and they were certainly not based on microprocessors in the '70's. I guess the LSI-11 (around 1975) was DEC's first single-board computer, but it didn't have a single chip CPU.
They provide a "best image?" tool for calibrating the location of the photo, and other ways for users to customize/modify the returned data. Some folks have noted that this may invite abuse from users.
Remembering that this is Amazon, they can limit updates to logged in users, even to users who have made clean credit card transactions. This would help eliminate most abuse.
Some have noted that the locations are sometimes off by a block or something. I noted above that you can correct data for a location with their "best image?" tool. If they are clever, they can use this data to calibrate neigboring sites as well.
Graham seems to emphasize that the important thing is to get busy. To me, being goal-oriented is about having the end in sight. If you don't understand what you will want the end to be, it's too soon to choose a goal. Graham is more interested in having young people learning about themselves and the world.

In case you're not that familiar with English, the author's name, Travis Tea, is a pun on the word travesty, which means farce, parody, or satire.
