Once you reach geosync height, you have orbital velocity provided "free" by the Earth's rotation. The geosync station isn't held up by the cable at all. The cable is held up by a counterweight just beyond geosync.
Actually, clock speed has a lot to do with Moore's low. Moore's law is about increased transister density. Increased transister density translates directly to higher clock rates.
Anyone know if it really requires an Ultra Sparc?
'Seems like an odd thing to do. There's not much need for 64 bit addressing in something like this. The last time I tried to build Gnome on my tri-processor SS10 it was quite slow and painful.
Certainly using FPGA's reduce the ammount of wiring but they don't eliminte it. You still have to connect the FPGA to swtiches, analog parts, edge connectors, etc.
A few years ago, I built a high speed serial board. I put everything I could on the FPGA becuase I didn't want to have to deal with the interconnect. But I needed to wirewrap connections to:
1) Configuration PROM for the FPGA
2) Clock
3) Tranceiver chip
4) External SRAM
5) Edge connector
6) DB9 for the serial cable
7) 8 pin header for in circuit reprogramming of the FPGA.
8) A debug header so I could reliably connect the logic analyzer to figure out what the board wasn't working.
I agree. The advantage of the digital age is that it makes it practical to keep things like correspondance. I've been archiveing virtually all the personal email I send or receive since 1989. There's no way I could justify keeping that much paper around. But in electronic form it is hard to justfiy not doing it.

You mean *distort* the playing field. Shipping & handling is a legitimate cost of doing business. If S&H raises e-tailer's costs above those of brick and morter then that means that the the e-tailers are less efficient than in-store merchants. They deserve to die.
I wonder if their decision has rendered their product useless for the Unix market. We looked at one stand along file server box a few months back. It was cheap. It was fast enough. It supported NFS.
But it only supported Windows style access controls. We couldn't assign ownership to individual files.
There is no consistantly applied definition of what Computer Engineering is. In some schools it is a minor variation on CS, in other schools it is a minor variation on EE. And there are plenty of schools in between.
Confused? Well, so are employeers. They don't know what Computer Engineering is supposed to be either. That's bad. Confused employers are less likely to hire you.
So, don't confuse them. If you want to do hardware, go with EE. If you want software, go with CS. If you're not sure, get the EE, it's the more flexible of the two. (EE's can and do write software. Few CS's build chips)
I'm a CE grad. I do hardware. Long ago, I gave up trying to explain what Computer Engineering means. I just tell them I'm a EE.
I have less of a problem with the content of the ending then the way it was presented. So many hours spent giving out hints, creating wheels within wheels, and then 95% is revealed in drawn out expositionary dialog. It's as if the writers just got tired of the series and wanted to cut to the end.

Because the weather up there is really nasty. An open suspension bridge would be iced over much of the time. If you're going to encose it all, you may as well save yourself the structural headaches and make it a tunnel.
There are legitimate reasons to have direct port 25 access. The solution, IMHO, is to require ID confirmation and some sort of a deposit to gain port 25 access. It may take a few days to set up but that's no big deal for a legitimate user. 'Makes it pretty hard for a hit and run spammer though.
Actually, a better way is not to give an explicit limit but employ exponential backoff, like some news servers do. After a small number of messages, each additional message is delayed by an increasing amount. The delays soon become prohibitive.
If a user actually has legitimately need to send large quantities then they need to get a "bulk mail" account. No significant differences from a normal account except that the backoff is eliminated, identity confirmation is required, and an agreement must be signed holding the customer liable for damages if they do spam.
I wonder if it would be practicial to impliment some form of exponential backoff in a router. 'Be tough to distinguish spam from large attachments I suppose.

The debug messages are a little annoying, but you can just redirect to/dev/null.
You can? When I run Konqueror, the debug messages come, not from Konqueror itself, but from all the deamons that it spawns. How would I direct that output to/dev/null?
The TLD spectrum is practically infinite, bounded only by length at n^26 possible domains. While some are more
desirable than others (as it's generally easier to broadcast over certain ranges compared to others in regards to power
consumption and signal quality), all are effectively possible
If TLD spectrum is infinite than the.com spectrum is also infinite.
If we already have infinite space then why do we need more TLD's?
If we are woried about existing TLD's filling up, then shouldn't that tell us that we should be worried about the top level also filling up?
Actually early RISC designs ran at *lower* clock rates than contemporary CISC chips. Their advantages was that they could be fully pipelined, completing an intruction on every clock cycle. CISC machines of the time required multiple clocks per instruction.
Nedit has an intuitive and efficient interface combined with enough power for non-trivial work. That is remarkably rare among text editors.
Some editors are extremeley capaable. Emacs certainly has a richer feature set then Nedit is likely to ever have. But it comes at a price. The interface is not intuitive and many moderate operations require complex interaction.
vi can be highly efficient in terms of keystrokes but is also unintuitive and lacks the raw power of emacs.
There are many obscure X based editors. They are generally easy to learn but terrible to use and seriously lacking in power.
Editors are such a personal thing. Little nuances can change everything. Emacs vs vi is not enough choice to choose on nuances. Adding Nedit still isn't enough but it's better. I would say we need at least 5 generally useable editors. (i.e 5 editors that will do virtually any job you want. Pick one you like)
1) It was too expensive for the desktop market.
2) It was too slow to be a workstation. The 680(30|40) wasn't anywhere close to the RISC workstations of the time.
3) It was too late to have a chance. The last successful new platform was Macintosh. Linux isn't really a new platform and the only reason it survives is that it's free, entirely optional, and doesn't require a revenue stream.
Politics is a funny thing sometimes. Governments can only raise taxes (whether by raising the tax rate or by closeing loopholes) when they don't need the money. If they wait until the next recession, when the surplusses are gone, it will become a political hot potato that no one will touch.
If there were no Microsoft then likely IBM would have bought their OS from Digital Research. PC's would have started with CPM/86 and gone who knows where.
What you suggesting is that Apple would have won, if the *IBM PC* never existing. It is possible but there were many contenders in the early 80's. Apple's Macintosh was only of them. And if IBM PC hadn't taken over, there would certainly have been more. In a world without the IBM PC, we might be typing on Amiga derivetives now. Or maybe the dominent machine would be something that was never born in our own timeline.
If you lower the noise from the fans such that the hard drive noise is now dominent, then the next step is obvious:
Get quieter hard drives. They do exist. My IBM 18ES SCSI drive is much quieter than the Baracuda that it replaced. A hair faster too. Now the dominent noise source is the fans inside in the Sparc. (used to be external drive case fans). That's going to be harder.
So to summarize here's the path that I took.
1) The Baracuda4 was the biggest noise source so I replaced it with a much quieter 9 gig IBM disk.
2) Next the external drive case fan was the noise king. So I replaced it with a much quieter (and slightly lower volume) fan from Digikey.
3) Now the impulse noise from my news disk mounted in the external case was noticeable. I stuffed the disk in a SilentDrive. Impulse now nearly inaudible.
4) It's much quieter now but there still a significant amount of noise comming from Sparcstation's fans. This is where is starts getting difficult. My best guess is that I'll need temperature sensitive, variable speed fans to do much good.
And very limited spread. IIRC, 6 bits of real data for every 8 chips sent over the air. Consider yourself lucky if it works at all with another 2.4Ghz device.
Oh please. Why would a nuclear power plant take significantly more energy to construst than a coal plant? Methink this "analaysis" was based on a rediculously short operating life. Provide a cite....Ah, I see, you don't have a cite. In other words, it's just you vague memory. That explains much.
As for disposing of nuclear fuels. We do know how to dispose of it. There has been a plan ready to go for over a decade but the NIMBY's an pseudo-environmentalists keep putting red tape in it's path.
What we don't know how to dispose of is the orders of magnitude more waste generated by coal plants. Have you seen what happens to all the tons of soot captured in the scrubbers of a coal plant? It's buried in shallow tenches. Just barely different from just dumping it into the environment. That there's the stuff that goes up the stacks, which *is* just dumped into the environment. There's so much of that coal plants release more radiation that nuclear plants, just from naturally occuring carbon-14.

Becuase no one is ever home during the day when deliveries are made. I always send packages to the office.
Frankly, I don't see how mail order houses who won't ship to an address different from the billing address can stay in business.

The concept has been around for a long time. Paper designs aren't new. But real, flying scramjets are another matter.
Ramjets that slow the air to subsonic speeds before combustion are old hat, of course.
