Mu metal can shield the field. In fact the instruments for which these are steering magnets make liberal use of Mu metal (gee I wonder why).
As to the multi ton stress, yup, I'm betting that next to a superconducting magnet (and associated cooling system) big and robust enough, this will be the major design challenge. Now, we know that there are materials out there that can handle the load (think super sky scrapers), but repeated load cycling would make an issue of it. I'm thinking something like high purity glass or synthetic saphire rods longitudinally embedded in concrete of approprite strength should do the trick of secondary load bearing and dissapation. As to the primary load, some sort of glassed steel may do the trick. -nB
"but I still would doubt if we had magnets that powerful. "
Sitting in front of me are two magnets. 1x1x1" at 1T and 3x2x2" at 2.5T I can not press those two magnets together with anything in my shop, including a 25 ton screw-vice. Since these are not nearly as powerful as available in non-superconducting configurations, I'm rather confident that the superconducting versions will have no trouble with the repulsive force. What I would worry about is the atomic iron in your blood being "borrowed" by the magnet if you are too close (IIRC that happens at ~10T) -nB

"not able to get native support for multiple monitor configurations from Microsoft until W2k"
I had no issue with dual monitors on WinNT4SP6a. Granted if you maximized a window it went over both screens, but it was nearly the most plug and play thing on NT. (granted teh bitchen nVidia driver likely did help).
I think with some work I had dual screen all the way back to NT3.51 and Win98SE. -nB
"What you don't know is the actual layout of the circuitry on the chip"
You also don't know: What signal paths operate under which micro-ops any "skeletons in the closet" being worked around with microcode
Same goes for the binary driver blobs. I'm somewhere between with Intel and with Theo on this. Binary drivers allow you to hide tweaks that are needed to ensure operation but that you don't want as general public knowledge.
"Hacking (in the illegal sense) is completly different than working on a difficult project for a company."
Not so much as it would seem on the surface. The rush, sense of accomplishment, and other such stuff is really similar. The best is when it's a customer issue (as was the arming of the LA from an LED), where the expected unit volume is in the mid/high hundreds of thousands (at $15 per unit you can see where this is going), and the problem has to be solved in hours or the deal very well could be off. That's a rush. It's also nice that the engineering manager says WTF? at the sight of the mouse and decides that it's the coolest solution to a problem of that type he's ever seen.
Fair enough, I said that wrong. I would likely not hack the company even if I was bored stiff. Lets say being busy is the candy to keep me coming to work;) -nB
So we used about a hundred deskstars in a simutanious install. I noticed that all the units from Turkey were great, while the asian country of origin drives (don't remember which one) sucked ass. When it came time for RMA's I requested that all the replacement drives be turkish. Also, (I think being a large company helped) we only had to send in the serial number sticker from the top of the drive (We drilled holes in the drives themselves). -nB
I was about so say something similar, but instead I will expound on your post. I am a former "black hat" as the media would portray it. While I never did anything knowingly illegal for profit, I do/did hack systems for entertainment.
I was employed by a small company where I rapidly rose to the position of being a network admin for a lab that dealt with ethernet equipment and components. Some of our gear was capable of generating arbatrary data frames (sourse/desti IP & MAC address, any length up to 20Kbyte (1518 IEEE spec is 1518 Byte), any interframe gap down to ~4nS (spec 9.6nS)). So to say that the network took a punishing when some dimwhit plugged the test side of the gear into the support network is a gross understatement (said support network was directly connected to the corp net, which went down when this happened).
I was given a budget of a few tens of grand, a spare Cat7K router, and told to "make it work" so I did. I got to hack my self silly doing that job and maintaining the network. Just before we were sold, that lab had ~400 nodes of well mixed clients with hostile traffic patterns and I was able to maintain connectivity.
The key to keeping me from hacking the companies assets was to keep me busy. Safe to say I bet the same goes for any others of my ilk. In my new company I have the Hacker creedo up on my office door. Just took the hacker creedo label off it. Everyone thinks it's the best statement since sliced bread. They're blown away when I tell them what it is. My management knows I'm a hacker, my peers know I'm a hacker. My IT department is less than loving of me (as I've modified thier standard windows build to suit my needs) but the know I'm a hacker and they tend to let me be.
Basically it all boils down to the following fact: I presented that I'm a hacker in my interview. I presented samples of my work. I was hired. This in a company of ~80K employees. My bosses-bosses-bosses-boss knows me by name. When we have a really sticky technological customer issue, I seemed to get tapped fairly predictably. From manually re-balling a 72 ball BGA part to hacking a mouse such that when an LED on a customer design turns on the logic analyzer will arm, I do it all. My best asset is my inner hacker.
Maybe not a bank, but I got very bored one day when talking to Delta Airlines phone computer. I started saying random gibberish and various swear phrases backwards "uoy kcuf"* and such. Ended up accessing some maintenance subroutine or such that seemed to have the ability to list all prompts by menu tree. Likely could have gotten farther, but I really was trying to book a flight so I hung up and started over. -nB
I love WAV recorder. It will let you reverstethe WAV and play it back. Learned everything backwards by wrote. Damn difficult. -nB
Heh, Not really. This chip (as designed) would be one CISC CPU core and 80 Mini cores (kinda like Cell?) Anyway, where this will be awesome is in rendering &&|| Cryptography, where the memory bandwith requirements is not as high as CPU compute requirements.
I personally hope these come out in a 4xPCIe expansion card:) -nB
FWIW, space, while cold, is a horrid conductor of heat. One of the bigger problems in space (at least in earth orbit) is how to get rid of the waste heat. I therefore doubt you will be dead of cold, vacuum, possibly (you've got a few minutes there IIRC) cold? not likely. -nB
Actually, I was simply stating that a serial port was all that was needed. Though the more I think about it, I would use a management node with a serial switch (integrated?) to send management data to all the nodes. Management data is fine at 115Kbps and saves all your 802.11 traffic for data.
This really is all rhetorical. We all know google has trained pidgeons pecking at front panel status buttons for this kind of monitoring anyway.

Can you honestly tell me with an electron scope you could figure out how the circuit was made Maybe not, but I can with the following assets:
FIB (Forced Ion Beam) E-Beam SEM (Scanning Electron Microscope) AFM (Atomic Force Microscope) Industrial espionage Hiring some of your key staff Bribing your FAB &&|| Foundry (especially if in APAC) Bribing your customers (they often have datasheets not publicly available)
(honestly I don't need all of this, various subsets can accomplish the same end results in varying ammounts of time (days, weeks, monts. Always < 1year)).
Ask me how I know (Hint, my company has both been on the receiving end and giving end of this. The giving end was to prove/disprove whether they stole our design. They did.) -nB
Like the european cup o noodles (Tesco I think) that has: "Warning contents may be hot" printed on the bottom of the stinkin cup?
While I am a big fan of the "he was obviously a nit, your honor" defense, it is not only the US that has nit protection warnings on products.
It is our sue happy nature, however, that I think was largly responsible for the multitue of iterations of: "Don't be stupid using this product" labels. -nB
