It's _really_ _really_ expandable (1 pci adapter -->8*16 devices, configuration is realatively easy as well (unlike scuzzy)...
and performance is quite nice. Stuff is more expensive (notably, the bus adapter and cables) but the disks are OK -- I've seen seagate 9.1G hd/~100 (7200 RPM).
FC is dope... but not cheap. (I work for a fc consulting company right now).
I remember checking out the prices at pricewatch for 9.1 gb, 7200RPM FC drives -- I don't know how they are so cheap, but some their cost less than $100 with shipping.
When you starting talking about HBAs (Host bus adapters) the money comes in... they are around 1,000 bucks. Plus, you've got to get fibre channel hubs to connect the disks, etc... However, the speeds are incredible. Plus, a single card can access something like 16*8 different disks...
driver support is also a problem... I don't know if linux currently has any good HBA drivers yet...
Damn, this is an incoherent post. Main point: FC is incredible and incredibly expensive.
I don' t know about everybody else, but every time I hear "the gang of four" I keep thinking about the Gang of Four -- the Cultural Revolution Small Group that inflicted so much terror and damage on China.
I wonder if the "gof" book is supposed to be a play off of that _real_ Gang of Four. If so, it kindof bothers me -- I mean that's sortof like naming french fries after Stalin (Russians like potatos!) or a music album Pol Pot, right?
Maybe I'm just looking for trouble, but do you think it's deliberate?
japan = no military. singapore = no military australia = small military russia = recently been very close with China, probably on China's side (against us hegemony)
who's left. India? (doesn't like china much at all...) small military
besides western powers, there's only south korea = _big_ military that can do anything. Plus, with the north korea situation (and nk being so close to China) they might not want to super jeopardize themselves either).
Fibre Channel is a pretty damn promising technology, but it doesn't seem to have hit mainstream 100% yet.
FC currently runs at 200MB/s (nearing 2Gb) for bandwidth, and a single "fabric" can take an almost infinite (2^24) number of devices... (of course the host computer understands it in SCSI terms, and can only address 1024 on a single card...

different: some of the people on slashdot are experts in their fields, and the news happens to concern them. If an article is posted about, say, the Usenet Death Penalty, within a couple of hours there will be a whole bunch of links to UDP sites, people discussing the last time their was one, and what in particular some news-server admins did to prevent whatever abuse.
This, although it's a bit roll-your-own, is basically everything you'd want in a well written article. The difference is you have to do the mind-work yourself.
I agree that I'd never trust slashdot re: foreign policy or !news_for_nerds, and all of the posts about China are usually one sided, etc. but for techical stuff (i.e. the new MS buffer overflow) who better to ask then a bunch of admins and people who've written buffer overflow exploits before?
Not only does it create an environment that probably makes most women in the business (there may be few, but they do exist) feel uncomfortable, it also enforces the "boys night out" feel of trade shows...
It is also a bit distracting (like most marketing, but this type is _completely irrelevant marketing -- the Alcatel babe on roller skates.... yum. I guess Alcatel really knows how to take care of their customers...)
My experiences might be a bit prejudiced (The last ones I went to were in China were this type of stuff is a bit more blunt) but it's really excessive...

It may be low quality, but it's rare that I've seen someone who doesn't want to watch a movie because it's just too low quality...
The reason why you'd want to check the X-Mailer is to see who is sending the message... but the overall goal is figuring out who READS the message with WHAT client. Therefore, things like your scripts, etc. should be tossed out from the get-go -- they give no useful information about what a particular person is using to READ the message.
(i.e. if I send mail from hotmail, then I probably read it from there too... I probably don't read mail from/bin/usr/mail, and if I do, I'm just a player then and I don't need to be counted....)

there are a bunch more, too. Notice how some of these don't represent a mail client that somebody's actually using (a coldfusion client? sounds like a form to me) and thus shouldn't be counted...
Also, some things clients might need to be teased out (pine, hotmail, aol (v5?), etc.) but they probably all have unique fingerprints like below...

I was just thinking -- Eudora, et al are probably really popular, but doesn't AOL have something like 23 million users? (is that users? or accounts). Hotmail and Yahoo also have some crazy numbers as well -- not to mention a lot of other similar webmails (usa.net?) that are probably a bit smaller.
I'm sure in business outlook is pretty big -- but most of the students I know use Eudora or plain'ol webmail... (I myself use pine).
I don't understand why people don't configure an email server with logging to figure this out -- like so:
1. Find population that you're interested (say mit.edu addresses) 2. have the SMTP damon on mit.edu save the X-mailer headers, devoid of any personal data. 3. Make statistics...
I mean, granted lots of people may use different smtp servers (you'll miss some of the CS folk) but at least it'd be realatively accurate...

Can someone knowledgable tell me why they can't float a very small buey up to surface and do some sort of satellite uplink? or maybe link to some superstrong overhead plane or something?

there's gotta be some way-- the bueys would have little underwater noise, right? and no other bueys required... probably a bit expensive, but sounds cool to me.

I don't know where you're shopping... but in China, the going price for software is $1.25 US/disk of pirated software.

Man, those were the best. Pascal was my first programming language, and I used those things like crazy.
The one thing that I do have to say about paper manuals is the bathroom factor. I've learned a hellof a lot by taking manuals with me into the bathroom on longer trips. Screens just don't cut it for that type of stuff.
