I worked on the design of parts for the DS2 aftbody. The deceleration forces in the aftbody are roughly 80,000g over ~1ms. The wide bandwidth of this impulse gives it a roughly white frequency distribution out to 1kHz. So the craft was designed with all resonances well above that freqency. Surprizingly, it's not that difficult to build (and test using an airgun at Sandia) electronics and sensors which will survive such a deployment. The clock crystals are one of the most vulnerable parts and _are_ necessary for telecomunications. It is ultimately a technology demonstration mission, but a rock would definitely put a hole in it. That's why they're dropping two...
I have to concur, with this assesment of NT. I've done a little work with NT, and what scares me is how "easy" it is to get things working. By working, I do mean stable w/o reboots for many months with real load. OTOH I know that there's lots of stuff going on under the surface that I don't know about... because it hasn't bitten me yet. With *nix I gotta know my sh*t to get it to work in the first place (ok there are RPMs), but with NT it's like "magic";^) Unfortunately, in NT it remains magic till it turns into bad voodoo. Call me conciously ignorant.
I watched my girlfriend go through this. She seems to have beaten bact CT, for at least a while, by using borage oil (an anti-inflammitory), and Glucosamine Sulphate (which seems more for cartilage, but she swears by it). These along with some changes to environment worked pretty well. YMMV
I know that the vertical mouse she switched to is good even for my somewhat less used scientists hands. I can tell the difference between it and a standard MS mouse after about 20 minutes. It is held like a joy stick, but moves like a traditional mouse.
Oh and definitely do some ergonomic work to: * remove weight from your wrists/palms * put your keyboard/mouse/monitor so that you don't have to hold yourself in a strange position to work. * take breaks! (You've heard this all right?)
All in all, I'm not sure why she got better. When people have this kind of problem they usually try so many things to make it better that the control of the scientific method seems to take a back seat. On the other hand, she's only been programming 15 years, and could develop problems again (probably at the highest stress crunch time... can't quit...must work... perhaps then I'll get a chance to run real experiments:^(
Here's a review of the mouse I like: http://www.mactoday.com/mayjun98/Anirmse.html and the Norwegian folks who make them: http://www.animax.no/webshop_world.html you can buy them at Fry's or on line, I'm sure.
p.s. No I don't work with or for them or anyone else who pays me more than living expenses.
