I worked on the ground-based simulator for one of Dextre's arms. It was installed at CSA headquarters in Quebec though, not at JPL. This was back in 2000 though... maybe it was moved. Man, if you think Dextre is intimidating, the ground based payload-ops arm had to do the same things, _plus_ have to offset 1G (gravity). I called the thing Darth cause it was black and had a mean temper. The thing was capable of holding out 100Kg (plus its own weight) at full extension and move it about with ~ +/- 1mm error, that takes a bit of power...
It's actually used to (heh) mount a satellite or other object so that it's stable to work on. Kind of hard to wrench on something when its floating around.
we worry more about anthrax (with an annual death toll of roughly zero) than influenza (with an annual death toll of a quarter-million to a half-million people)
Well, there's no little $100,000.00 box that goes beep in the presence of influenza that I know of. If there was, then we would be all in-terror of the next outbreak of it, you can count on that.
These types of generators are great as you can use very simple wind-powered cyclic motion devices to power the generator. You could even use a tree branch that was moving in the wind. Saves having to pull the string yourself.
Personally, I'm more interested in diesel power (utilizing vegetable-based fuel). The technology is already 100% available, very well developed, mass produced, and it can utilize the existing distribution infrastructure without serious modifications (I think that oil pipelines would need some help, however). Burning vegetable-based fuel also releases zero net greenhouse gas, since all carbon released into the atmosphere was originally metabolized from the atmosphere
I like that, thats funny. Of course you realize that oil is mostly plant-based. So using your arguement, by burning it we are also releasing net zero gas... it just took a little longer to return it... and the net result is that the world climate will be back to the condition it was when those plants were alive.
[Extrapolation] Maybe the climate change was not caused by a meteor or anything, maybe the plants just removed enough CO2 to weaken the greenhouse effect... enought to cause the climatictic shift that killed them off...
Just thought that was an interesting point to make...
You sure that it was ultrasound therapy? It might have been electro-magnetic pulse therapy... thats been around for a while. It's typically used to stimulate bone regrowth.
The difference is that the code in slamd64 is optimized for Athlon64/Opteron, a feat which is entirely doable by anybody who knows how to compile a kernel and their own software
To be truly an effective 64 bit OS, everything must be compiled for 64-bit, starting with GCC. This means that all apps, such as bash or the X-windows server/client are running natively in 64-bit mode. You can run the OS in 64-bit mode and everything else in 32-bit mode, but I don't see the point, other than a faster kernel.

70's and 80's SF have explored the idea of processing lunar raw materials then launching it such that it falls back to an earth orbit. The materials would be used to construct spacestations et al.
Energy-wise it's a good idea but the expense of getting an ore factory and a railgun (for launcing payloads) going would be incredible...
You are thinking of http://www.google.ca This is http://local.google.ca. The front end is different, designed for business et al lookups. I just tried it out, typed sushi & Vancouver. Shows a map with all the sushi shops downtown... cool.
I mean, when you sit down in front of a computer with that blinking cursor, you intend to do something with it right? The only reasons I know of why someone would want to use a tty session is to manipulate/crunch data or control processes. Use X for office activities, eg word processing.

Step #1, everything behind that screen is a file, and can be treated like a file, hell you can even edit a directory. Also, there is ALWAYS more than one way to do a task, usually more than two.
Indeed. You INVOKE a daemon by FORKing it into a seprate process whereby it may EXECUTE other processes via children, then on a whim, KILL it's child process.... insideous.
It's more likely that every persone on the planet would get a subnet, so they can assign their own IP adress to their appliance. Children could get temporary IP addresses until they become adults. - I dunno...
I think it was a static discharge, caused by using the phone. Here's my theory.
The guy gets out and starts pumping gas. At this point he has grounded himself on the pump, possibly the car too.
Phone rings. He lets go of the gas nozzle. Does it keep going? I dunno, depends on which pump he is using.
Reaches into his clothes for the phone. Phone possibly has a leather or other cover on it. The act of pulling the phone out builds a discharge.
He then grabs the nozzle again... discharge & kaboom.
So the phone itself it not to blame. But it was a factor.
Morale of the story - don't go rubbing balloons on your head (so to speak) while not in a grounded state.

Step #1, everything behind that screen is a file, and can be treated like a file, hell you can even edit a directory. Also, there is ALWAYS more than one way to do a task, usually more than two.
Step #2, learn man, cd, ls, mkdir, (some editor eg. vi/emacs)
Step #3, pipe is your friend. stdin, stdout (stderr later on).
Step #4, commands don't always have to accept data from you, most will accept data from other commands AKA using Step#3.
Step #5, shell scripting. so you don't have to keeping retyping everything over again.
Step #6 job control fj, bj, jobs. So you don't have to open another tty session.
Step #7 process control. ps, pgrep, kill, pkill, ctrl-c, ctrl-z. So you have some way of stopping a runaway program.
Step #8 Rudimentary data processing. grep, sed, awk, tail, more, less & of course cat.
Step #n, writing your own tools. C, Perl, Python etc.

1) open web broswer and goto www.google.com
2) type "building 2.6.0 with redhat"
3) browse results.
Or, goto kerneltrap.org, for eg.
http://kerneltrap.org/node/view/799 - a nice article, but slightly outdated now.
The biggest gotya is the requirement for a new modutils prior to running the newer kernel. Read the article for more info.
