I've never seen the word "Pringle" (singular) used before. And yet, we all know exactly what it means.
Speaking of which, I could really go for a Twik now.
what sort of project did you have in mind that would be easier with an open source mechanical CAD package? I guess I'm trying to understand the scale and scope of such a project and what sort of CAD you would need (2D/3D/both)?
Both. My own project is CandyFab, but there are a lot of other cases out there where such a thing would be helpful. The Openmoko design files are released in Pro/E, for example-- not exactly free software.
It never seems like a project is really "open source" if you need a $1000+ piece of software to open up the design files.
I can say that two of the kits in that list (which I designed) *were* designed with gEDA and have the pcb design files released. I don't know for certain if any of the others are.
I *really* wish that there were good open source CAD tools for mechanical applications as well-- it would make a lot of other projects easier to release as fully open source.
>Does No Child Left Behind mean that nobody can get ahead, either?
Of course it does. If *any* child gets ahead, *millions* of children are left behind that one. I have always referred to this program as "no child gets ahead"-- it's turned out to be remarkably accurate.
Also in the news this week is the opposite result: that life cannot exist in comets because of the radiation.
So... it's not obvious (to me) that there is any scientific consensus on this topic.
The work with the CMOS circuits is clearly an important achievement.
However, both the Slashdot title ("Record High Frequency Achieved") and summary ("...managed to push our control of frequencies to another level...") do seem imply that frequency control has not been possible at frequencies that high before. So, it's important to point out that while it's a record, it's only a record within context. (Records within context are fun; you can do anything with them. For example, I hold the bicycle land speed record for all persons with my SSN.)
In any case, it's *not* totally different. Both are examples of frequency control, which is it's own discipline that spans precision timing and applications in all frequency ranges, from RF (on chips and in free space) to optical (on chips, in fibers, and in free space) and beyond.
Precision phase coherent control of lasers has become possible in the last ten years- Laser beams at frequencies exceeding 1 PHz (10^15 Hz) have been precisely controlled, phase locked, and tuned to have frequencies that are *exact multiples* of our best microwave frequency standards (e.g, cesium). It works the other way too-- our most precise microwave-frequency signals come from divided-down optical frequency references now!

Five years ago I had a website with a collection of jokes collected from mid-1990s humor mailing lists. Naturally, there was a whole page of Barney jokes. The same stupid ones that you've seen a million times. You've seen all the song parodies (here, if nowhere else), and then there was the giant ASCII-art-Barney-being-killed-by-something.
I think that it might have been a face hugger.
At the time, the web site (for stupid, complicated reasons) was registered in my father's name. So, imagine my old man's surprise when one day HE gets a letter from Barney's lawyer threatening (purple) fire and brimstone. Without much of a good alternative, we caved. I was really, really mad, and I suppose that I still am. To this day, it's the only legal 'trouble' that any of my web sites have stirred up, which is actually somewhat surprising.
Now that someone has finally stood up to the purple bully, can I finally dig into my old backups and put up the page of Barney jokes again? Whether or not Barney jokes are still relevant at the end of 2006, I suppose that I should, merely on principle.

Reminds me of the classic joke:
A college physics professor was explaining a concept to his class when a pre-med student interrupted him.
"Why do we have to learn this stuff?" he blurted out.
"To save lives," the professor responded before continuing the lecture.
A few minutes later the student spoke up again. "Wait-- how does physics save lives?"
The professor responded. "By keeping idiots out of medical school."
A few months ago I wrote up a post wondering why no one had done this yet. Put those accelerometers to work!
These atoms are color coded, not *seen* in color by the microscope.
I think you missed the joke.

I can't believe that you used "trustworthy" and I.E. in the same breath.
Seriously though, I can't imagine just "leaving the internet," for any reason whatsoever.
"So why are you wearing clothes?"
I wonder how much of this thing goes on that we *don't* hear about.
Will someone in the US government please do the same?
I follow you most of the way, but I'm not sure how arsenic, cesium, and darmstadtium fit into this discussion.
On the other hand, thermoelectric devices with significant capacity are pretty expensive. This might be a much less expensive route to the same goal.
(On the third hand, this is military funded research, so I'd be a little bit surprised if that were the make-or-break feature.)

predict that the first post will have something to do with our new robotic overlords....
I really don't want to share, whether it's academic or not!
I wonder how long they've been sitting on this!
I have a first-rev MacBook Pro with the Core (1) Duo. I *wish* I could upgrade from g to n for only $5!
I built up a laser experiment that cooled some metal atoms to about 400 nanokelvin-- that's the coolest that I've ever gotten anything!

Are you sure about that?
