Why isn't the informed crowd playing up the fact that encrytion is key to computer security? That is, putting it into words that Congressional-types can understand and fear. "Such and such incident where that hacker (technically cracker, but they fear the word hacker.) stole a zillion credit card numbers from SomewhereImportant.com could have been prevented if they ONLY used encryption." "That break in where those hacker defaced SuchAndSuch.gov wouldn't have happened if they ONLY used encryption."...maybe even something is absurd as "That email virus could have been prevented if they ONLY used encryption."

I think is why this country really needs a middle ground party. You could see it during the elections how people were very content with the state of the union. Many didn't want the progressiveness of one party or the conservatism of the other, yet what choice did they have. The population as a whole was sitting right at the center, and from a statistic point of view it made perfect sense that this translated to a dead 50-50 split. However we live in a country where political viewpoints are binary, so a slight bit of noise tossed us full throttle into republican mode. That in control theory is called an unstable bang-bang system. We lack shades of gray, and unfortunately this election only forces both sides to take up their ideals even more fanatically. I'm not talking about a libertian party, or a green party. I'm talking about a "we're content" party that doesn't pass major laws (unless the situation warrants it), just keeps the day-to-day government running.
There is something called clock trees which allow every section of the chip recieve the same clock signal at the same time. This is done by dividing the clock lines in equal partitions until you reach each module in a binary tree manner. That way all the delays are taken into account. Also each module is pipelined like an assembly line where at each step a module only does one stage of an instruction execution, but from the outside world it's cranking out on average one or multiple instructions per cycle. With these and other tricks, delays in the propagation of signals is relatively no big whoop.
Gawd, why can't they start holding Microsoft just as accountable for these email viri by stupidly creating an email reader which by default blindly execute email attachments. I mean aren't there papers and stuff written years ago that explictly say don't write programs which blindly run executeables unless they're sandboxed. Isn't this the philosophy behind Java?
I didn't really pay heed to the onslaught of email viri until my adviser's day old Windows 2000 box trash itself while he was checking email after setting up the network configs. He just clicked on a subject heading to delete a message with an annoying subject line and BOOM! his machine was trashed and everyone in the department recieved the virus. That's irresponsible programming. Why aren't people suing MS in addition to catching these writers? They're both equally accountable.
There is a really really cool algorithm called Diffie-Hellman that allows one to create a temporary key between two people one of thin air which both can encrypt and decrypt a message with and then throw away.
Each person agrees on a large prime number, p, and a base number g less than p-1. This could be hard coded into the software or generated when the user installs their software.
Lets use p=7 and g=3
Now lets say person A and person B wish to send a secret message using a temporary key. Both use p=7, g=3. First both generate a random number that's less than p-1 called r.
Person A uses r=2
Person B uses r=6
The users then compute y = g^r mod p.
Person A computes y = 3^2 mod 7 = 2
Person B computes y = 3^6 mod 7 = 1
Then each user transmits y to the other person. Next each person computes x = y^r mod p and uses x as their secret key.
Person A computes x = 1^2 mod 7 = 1
Person B computes x = 2^6 mod 7 = 1
See, both x's are equal to each other and the only thing the outside world saw was 2 and 1 exchanged between each user. As long as the outsider doesn't aquire each user's random number r (which the user throws away once a key is generated.) they cannot find that agreed key, x, without brute force trying every r. Of course p needs to be huge for this to work. BTW, look up modulo arithmetic to compute a^b mod c without calculating the huge a^b.
That's how a peer-to-peer network can send encryptions between two users without the middle person knowing or storing any public keys between the users. The only hitch is preventing man-in-the-middle attacks but that's another story.
The other thing that makes Palms rule is the power consumation. Not I own a Win CE/Pocket device, but reading reviews on Amazon, people say that these mini notebooks typically last about 6 hours before a recharge. My Palm IIIxe lasts about a month on 2 AAA.
I don't want to cough up cash for a handheld monster that's one step short of a laptop, I just want a device that doles out information like a pocket watch tells time. I carry it in the front pocket and I pull it out to jot down a price, lookup a word, arrange a meeting, or past time paying solitare. It's a quick on, compute, off, back in the pocket. That's what makes them successful.
We have the momentum of a zillion people here, why don't we just get our arses in gear and form a special interest group to as least inform, if not pressure, Congress to see the stupidity of all this. This is evidence towards why Microsoft should be broken up.
You won't even want to consider using a CPU from a consumer product because they're not harden for military use. One good warm sunny day or a sudden change in temp from going 70F to -60F in the upper atmosphere and pop, the missile's brainless. Most CPUs in satellites and even the space shuttle are no more powerful than 486s because it takes at least 5 years of extra developement to get a processor redesigned and tested for such environmental extremes, plus they don't need to be anymore powerful. Read a few inertial devices etc. for positioning, recompute the correction and turn the fins.
Yes I totally recommend Serial Experiment Lain. It's very slow and painful to watch, but it totally eats into your head. I'd say the experience is similar to watching 2001 except that it lasts 6 hours.
Also Cowboy Bebop is high on my list as well because it has it all in action flicks except for the stupid name. It's a futuristic bounty hunter story with a marvious plot, well done animation, and blues/jazz soundtrack that can't be beat. Hell, the soundtrack is all I've been listening to for the past few weeks.
Heh, our research group needs fast x86 machines for medical image processing because 1) our customers want NT machines with nice happy Windows-based software to process life critical data (God only knows why.) and 2) Our professors have this attitude that we don't need to optimize the algorithms because machines will only get faster.
Ok people, this stuff has been pissing me off for quite a while now, so where's the petitioning, phoning congress members, active complaining? I mean why can't we take advantage of the/. effect?
Ok, so we have a reactionary government that takes everything at face value without thought. Why don't people start playing up the idea that because encryption isn't widely available or hindered our computers are subjected to cracking and shutdowns...put it in words they understand.
"The blah-blah-blah.gov site was cracked. That was unfortunate, but they left themselves wide open for not using ssh."
Somehow put it in their heads that encryption is an aspect of computer security, and start blaming cracking activities being caused partially by misguided cryto-laws.

Looking briefly over this I see references to ATA-based drives. Would this copy protection mechanism be applied to future SCSI drives as well?
