I'm thinking that hosts file listings of servers that are often targets of this sort of thing might be a good idea. I'd love to see a web site where I could download the latest list of hosts that privacy advocates would prefer to see denied.
How is it that Americans protesting their government's actions somehow amounts to their being apathetic? Seems QUITE the opposite to me.
Our founding fathers fought, and many of them died, just to avoid having a government that interfered too much. Perhaps this needs to happen again, but I'd rather see it not happen.
One of these days, the electrical engineering community will catch up with the particle physics community, I guess.
Re:Who Actually USES These Patterns?

I use patterns on a regular basis, at many levels of code. The best description I've seen for why we want to use design patterns actually came across my desk this morning.
If two woodworkers wish to describe joining two pieces of wood together for the front and the side of a drawer, they COULD, I suppose, discuss cutting a certain length, turning at a certain angle, cutting another length, turning the other way again, etc. etc. ad nauseum.
OR, they can simply indicate that they want to use 3/8"-wide through dovetails.... Concise, and providing just as much information to the informed. What happens is that there is meta-information underneath the words being used, conveying more than the casual observer might catch.
When discussing whether to use one pattern or another, it's akin to deciding whether you wish to use dovetail or mitre jointing for that corner.
When you write code, you're already using patterns behind the scenes anyway. It's nice to know what you're doing, and it's REALLY nice to have a shared vocabulary for this stuff.

Damn straight it's worth it.
As a developer, this book helps you to codify some concepts you've already got in your head, so you can latch onto them and understand them better. Patterns are applicable at every level, from little 20 and 50 line modules up to arbitrarily large systems. Get this book, or one based upon it that uses the language of your preference.
Those are the costs of production... That is, they produced 53 thousand ounces for 20 million, and years later, produced 500 thousand for 30 million. That's a ridiculous improvement.
What anti-intellectuals called this Flamebait? It's quite insightful, IMHO, and this division of humanity into three applies across MANY fields of study.
Hehe. I suppose they'll be sorry to hear this here... We do Java development against NT, AIX, Linux and OS/390. One code-base, One deployment strategy. And I can promise you this, the only OS-specific stuff in my code is... well, nothing.
Mind you, this is all related to server-side processing. Bringing in Swing/AWT and browsers just makes a mess of things.
And you're just as wrong as Patent commisioner Henry J. Ellsworth was in 1844.
Seriously, though. These things are actually good

Best High-Tech Toilet?

· Score: 1
My father-in-law has one, my brother-in-law has two. Not complete toilets, but WASHLETS, which are basically replacement toilet seats, with the built-in wash/dry functions.
They're great. They get you clean without going through masses of paper. That actually starts to feel rather barbaric.
Now, on the lighter side, these toilets are apparently not the most advanced models, which have multicolor fountains and announce that they are honored to accept your waste.
Not only has Kryotech been making -40 degree systems available for some time, they now sell empty cases with refrigeration units. You can buy one for 350-400 bucks US.
This is why the term 'molecular manufacturing' came into being. The people working on nanotech wanted to avoid just such confusion.
The MEMS which were discussed yesterday are not nanotech. They are vacuum tubes as compared with nanotech's transistors. The device illustrated here is 'pre-nano' or 'early nano', not 'sub-nano'.
Actually, the 'space elevator' idea is over 20 years old. Arthur C. Clarke and another author (whose name, unfortunately, escapes me at the moment) released books nearly simultaneously, which outlined this very concept. Once again, science fiction has beaten science to the punch.
I believe that one of the books was entitled 'The Fountains of Paradise'.

I propose that we teach the truth about the Universe: It's turtles all the way down. And the lightning is an angry god. And we have winter because a goddess' daughter was kidnapped by the lord of the Underworld.
So what if it IS akin to building a computer with vacuum tubes? Did we not have to go through that stage with electronic computers? The technology will grow in stages, with new developments building upon older ones.
Perhaps we should have waited for the Pentium chip before building any PCs.;-)
I was reading about this a few weeks ago. There were a number of ideas:
1) You can always run machines slower to slow heat production. 2) Reversible computing (another post discussed it) reduces heat dissipation. 3) I read of a suggestion for a coffee-mug sized ultracomputer with hundreds or thousands of gallons of water being pumped through per minute to provide cooling.
It seems to me that I know of at least one category of machine which consists of millions or billions of nanomechanical devices in close proximity, under continuous operation. It's able to operate at less than 100 degrees fahrenheit for years on end.
Don't confuse the current micron-scale gear experiments with true nanotech. These very small machines are called MEMS (Micro Electro Mechanical Systems?). There are actually production MEMS being used today in airbag sensors. They're very small, and very cool, but they are not true nano. They are built using lithography, with many of the same techniques used for integrated circuits. The true nanotechnology vision involves molecular manufacturing. Materials are custom built at the atomic and then molecular level. Individual machines would be systems of a few (or many) highly complex molecules with specific shapes corresponding to mechanical devices with which we are familiar.
A lot of people have put a lot of thought into this one. Early nanotools will be externally driven, possibly by pressure-activated pistons. Nano-scale computers will eventually replace these early, externally-driven devices. There are plausible, if unproven, designs for nano-scale computers, including a variety of non-volatile RAM. It's likely to happen. See foresight for more details.
What I want to know is: What do you mean by "And how big are these things going to have to start out, since the first generation must contain all sets of code for all generations of nanomachines?"
Why? Please don't confuse the concept of self-replication with the fallacy that we have to figure everything out first and turn it all over to the machines. Early nanotech will be macrocomputer-driven. It will, however, provide the tools to create nanocomputers. From there, it's still quite an engineering leap to get to fully self-replicating systems.

You say the key bottleneck is vertex geometry?
The next generation nVidia part (NV10) will have Geometric Transform and Lighting handled on the card. That's the end of that bottleneck.
Intel isn't too happy about this, because all of a sudden a 300 MHz machine becomes very gameworthy.
