640 == 8 * 80G. THERE ARE NO 80G U160 drives on the market. If we go by press spew, IBM has 140G drives. The largest SCSI drives one can purchase right now are 75G (from Seagate, Quantum/Maxtor, and IBM.)
Has no one done the math on the heat 8 x 10,000 RPM drives stuffed in 19" x 1.75" x 24" -- stacked 42 high? (Each drive draws about 18W of electicity...)

There are lots of sites around like that (I call it the near porn revolution)... The only conclusion I can draw is that beauty is truely subjective, but ugly is rather universal -- in a random group of people, it will be hard to get a concensis on beauty, however, everyone will quickly agree "damn, [s]he's ugly."
As an aside, I don't think the numbers are statically valid until there have been thousands of votes cast (like > 10000.) It's far too easy to stuff the voting (just like a/. poll.)
That's part of the problem. As you chop up the address space, the size of the routing tables grow. If the smallest set of contigous addresses routed on the global network is a class C (256 addresses) then you'd potentially have 2^24 (16 million) route entries. Even if the smallest block of portable addresses is limited to/20 (1024 addresses) the routing tables could potentially hold 2^20 (1 million) entries. That translates to a table around 16 to 32M in size that has to be inspected for every packet passing through the router. That's going to take a measurable about of time even if you wire it directly into the silicon at gigahertz speeds.
He pulled you over didn't he? In my experience (knowing a few cops), they'd rather yell at you than fill out the paperwork and have to appear in court.
Well, we still have speed limits. They aren't "selectively enforced", they are "randomly enforced." If everyone is speeding, then the cop can pull over any car he can catch:-)
There are a lot of illegal drugs in this country. They've always been illegal. It's bigger business than tobacco yet it's still illegal and looks like it will stay that way.
You fail to realize the DMCA exists because of industry. Hell, it was "written" by the MPAA's Valenti.
Unfortunately, it won't. There's too much economics and politics involved.
Personally, I don't want to be anywhere near this planet when the Supreme Court upholds the DMCA. Everyone worries about terrorists with nukes; try to imagine the US civil war being fought in an era with weapons of mass destruction -- nukes, bio weapons, incindiary weapons as powerful as nukes, etc.

It's called "IDSL" -- ISDN DSL. It's basically direct access to the HDLC signaling of an ISDN phone line. (no channels. it's just one big stream of bits.) It's expensive because they don't want to sell it and it's completely different from other xDSL setups.

Well, as far as the "not idiots" part, that's always a matter of interpretation. It has been my experience (I went to NCSU and worked there for a while) that alot of the stupid things the "IT staff" (that covers a whole lot of various offices) do would get them fired in the real world. Universities are far more forgiving due to the nature of the environment -- low pay, over worked, stress, etc. I really shouldn't fault them as it is difficult to do 12 hours work in 8 hours.
And no, they are not handing out the stock RedHat installation CDs. At least the College of Textiles had plans to include the software students would need. That was about a year or two ago. Six (6) years ago, I create a "stock" installation image for the COT. It was based on Slackware as redhat really wasn't usable for unattended custom installations. One floppy, a few questions (network info), and poof complete linux system complete with AFS, ZMail, the NCSU xdm, maple, matlab, xess, and the associated modifications to integrate it into the campus kerberos authentication system. It was (and still is) a masterpiece. Heck, it even flashed NT (or was it Windows 3.11) onto the thing. [I've still got it all on a backup tape around here somewhere.]
Well, with proper care, NT would work. UVa uses NT heavily and has for several years. However, one would not expect NCSU COE to use a Microsoft OS as they pioniered the large scale, wide area, UNIX infrastructure (starting back in 1986 as I recall. "EOS" it then expanded to the entire University (as the COE people "moved up") as "Unity".)
Unix is far easier to police on the >1000 node scale of NCSU. Anyone administering a cluster of NT machines knows how much trouble it is to do software updates -- each machine needs it's own local copy of just about everything. (There are companies that make good money selling management products for Windows.)
As for complete "Open Source"... matlab and maple will be tough to find an open replacement for. SAS is also used for some things, but I'm not sure how much undergrad's use it. (I used it _once_ in five years because Dr. Clapp forced us to.)
No it doesn't. The "crypto chip" is on a 9600 baud serial interface. That chip merely holds certain sensitive data (the serial number, keys, processing for chalenge-response handshakes, etc.) If you doubt me, strace 'bf' and watch how little information is sent to/dev/ttyS0.
(Also to note, while the crypto chip is active, the "Eye" is disabled. The LEDs go out.)
That's one (of many) reason(s) for ground planes in multi-layer boards. X-raying the board is next to useless -- it has to be decomposited (unlayered).
Heh, just "encrypt" it with some lame-o encryption and then sue them under the DMCA for circumventing your technology -- XOR it with your favorite constant (e, Pi, G, C, 0xdeadbeaf, etc.) Sure, any 3rd grader could crack it but that's what the DMCA's for.
Does anyone understand what is wrong with this picture?
You don't even understand the picture much less what's wrong with it. The watermark is basically a serial number integrated into the audio/video file to identify the owner. There is nothing (read that again: NOTHING) about the watermark that prevents the creation of exact duplicates - period. You can make as many copies as you want and they can all be traced back to the authorized owner in the event said owner distributes one of those copies.
MacroVision is a different story. However, it is perfectly legal for you to purchase a (perfectly legal) video stabalizer ("macrovision scrubber") and make personal copies of your video tape collection. There are VCRs available that are immune to macrovision and, in fact, will record the macrovision signal along with everything else.
some integer algorithms are FASTER with the IBM 1.3 JVM than the equivalent C code
Then either your C code is shit or the compiler you used to compile it is shit. JAVA is interpreted in order to be executed. If that's done inline, like a BASIC tokenizer, then your performance will be an order of magnitude less than the native code built by the worst of the worst compilers. JIT's translate JAVA bytecode to native code which presumablly the native compiler could have generated (with a few exceptions.) The output is on par and in some cases better than natively compiled code -- it is native code at this point. I've seen JIT JAVA code run at 90% of the native C++ code pretty evenly across a few platforms (sun jdk 1.1 and gcc 2.7.2 -- neither is really optimal)
What you are seeing with your "factor of 3:2" is a JIT vastly superior to your C compiler -- I'm guessing some version of a GNU compiler. Writing blindingly fast C code requires knowledge of the target platform. JIT creates an abstraction that places that knowledge on the VM designers instead of the application designers. This allows sloppy and "stupid" programmers to write surprisingly good applications.
I have nothing against JAVA as a language. However, I am catagorically anti-interpreted code. BASIC feined in light of C and C++ because interpreted languages give laughable performance, but writing everything in assembly made too many people sick:-) In my opinion, computer programmers should be taught to program first in assembly without a compiler (compile it by hand) and forced to key it in byte by byte. Once you appreciate that level of complexity -- once refered to by a fellow programmer as "moving a mountain with a teaspoon" ["sure it takes awhile, but you have complete control over every bit of the dirt"] -- then they can be introduced to C/C++/JAVA/etc. (There are any number of MCU's that can be used for such things. Programming in RISC ASM isn't that difficult to do.)
Try "SLS" on floppies... you get a lot of people looking at you strange for walking into the computer lab (to the _one_ workstation with a floppy which, I might add, few knew how to access) with box after box of 3.5" floppies. Of course, Linux wasn't very far out of Finland at that point.
No, what I'm saying is when any nut can walk into Walmart and purchase all the things he needs to go home and begin "ripping" DVD's you have a problem. We currently have this situation with audio CDs and data CDs -- data CDs are harder as one can get away with some Evil Tricks(tm) that cannot be done to an audio CD.
The point is, most people don't have access to the hardware and supplies necessary to make a true duplicate of a DVD-ROM with CSS and all that crap intact. What people do is transcode the DVD MPEG-2 data into MPEG-4 (DivX) or MPEG-1 (VCD) losing alot in the process.
As for "people"... DVD CCA is doing a good job so far. How many people have DVD drives that ignore region encoding? Very few. And after Jan-01-2000, no one makes non-RPC2 "region locked" drives. I know of at least one company that recalled every non-RPC2 drive not in consumer hands. How many people have DVD drives that ignore the whole CSS authentication and key exchange bull? Absolutely NONE. The physical format standard for DVD is publically available so you're welcome to start production of your own DVD drives. You would certainly be sued before your design ever got out of OrCAD.
RIAA, MPAA, et. al. like to bounce around on the notion of relizing or losing revenue, however they have never backed up a single one of their speculations. In fact, more content is available on DVD now than ever before. Are there entire warehouses of DVDs waiting for the 28th to roll around to release them? No. Additionally, everything available in DVD format is available in other formats as well (VHS, LD, even beta) And in many cases, the VHS versions hit the market first -- sometimes by months; this has nothing to do with law, it has to do with DVD authoring time... the VHS tape is exactly what you saw in the theatre.
The issue with DeCSS is of it's "piracy tool" nature. Yes, every idiot on Slashdot is going to argue it's to allow playback under <insert non-windows OS here>. HOWEVER, that arguement is full of holes and you know it. DeCSS has done more harm than you can imagine for those trying to bring DVD to alternative OSen. Never argue that you are helping Linux by creating and sharing windows programs.
As for DVD playback outside their circle, they don't like that idea. Any unlicensed DVD player would be beyond the DVD CCA's contractual scope. "Fair Use" has become "however we say you can use it." They are afraid of losing control over content that can be perfectly and indistingishably duplicated. It's all digital data; you cannot prevent copying -- even Microsoft has been unable to stop it (argueably, they don't want to.) The best you can hope to do it make it trackable. Physical means of media control like watermarks and eliptical tracks can help to stop the small time theft, but nothing will ever stop the "pros".
It doesn't matter for what purpose you intended your creation. A screw driver isn't a hammer nor is a hammer a screw driver but each can fill either job.
Heh, you cannot blame Microsoft for crappy 3rd party software. 90% of the problems seen with windows (and I'm taking NT here) is due to lame 3rd party software screwing with things they shouldn't even be aware of -- most notably replacing system DLLs (mfc*.dll for one) with older, non-compatible versions.
Case in point, the Clearcase 4.1 installer installed a Win95 3D dll which caused every GUI to fail until I removed it using the W2k "recovery console". People scoff at Microsoft's insistance on reapplying the service pack after installing or removing any component, but you really do need to.
As for supporting new hardware... you didn't say which Windows you are using. It doesn't matter. You are implying software written years ago (NT 4.0 is 4+ years old now) can support the stuff we're going to think up next week. W2k is certainly the newest version, but it's still older than the KT133. If the vendor supplied driver doesn't work, then that's the vendor's problem. I had that problem with my NT machine at work... nothing in that machine existed when NT was designed -- I had to burn my own installation CD to get it installed (NT 4.0 will not install from an LS120.)
I would but that turns out to be more expensive... HellSouth requires a LD carrier or they charge you a fee. I started to remove the LD carrier for my ISDN line as I never want it to be able to make a LD call. (I could always switch to BTI.)
and if you tell them to never call again they are required by law to not call you
Well, not exactly... MediaOne and AT&T are the same company. You (Hemos) have a business relationship with this company so the normal anti-telemarketing clauses don't apply.
Personally, I'm more pissed at AT&T calling to offer me -- an existing AT&T LD customer -- AT&T LD service. In the beginning, I would politely inform the drone that I'm already a customer. Now, I yell at them until they cry. (Alright, only one of them ever sounded like she was in tears. Most of them hang up after I start cursing.) It's not like the idiots don't know who they're billing. No, wait; THEY DON'T!

Yes, humans do have genetic immunity to certain diseases. The best known example is scycle-cell anemia -- those people are immune to malaria.
