But in the fab they do not need a centralized multi-processor server to handle very large loads! What they have is a distributed system with maybe hundreds of individual tools each with its own processor, and the programs running on these processors are rather simple, something like:
Wait for chamber lock to be closed, switch on that pump for 10 min, ramp this voltage at 1 V/min for half an hour, wait for an hour, open chamber lock.
Where is huge computational load here? OTOH, it should be done in real time and be flexible enough to access/reprogram remotely. This is the reason to use something light-weight (like Linux) and why they want WiFi (not to run 1700 ethernet cables all over the place).
By the way, are you SURE that there is a single high-end IBM machine for which wireless lan card exists?;-)
I'm wondering why would they considered Windows (apparently running on Intel processors), when from pure PR point of view a bunch of PowerPC-based machines (Macs, anyone?:)) would look soo much better. OTOH, most probably tool vendors do build Pentiums into their machines...
I'm wondering why they did not make a small chip with wireless receiver that would fit into the implant (it is like a "fat quarter", plenty of space to fit a chip in). This would save the trouble of having 1K wire connector on the side of your head...
At least they could've make it 2-3 wires (power and data) + a demux chip inside.
I guess the flag is -C and it does what you would expect: program checks bounds on any array access. (Used it a couple of month ago to track a really nasty bug in some ancient code).
I doubt this would be easily portable to the C/C++ side of GCC, because in C you have miriad ways to access the same memory location (via different pointers).
Of course, already mentioned Electric Fence is a really nice tool to debug malloc() problems (but not other types of memory overruns, like overrunning a static array).
Linker can put a 0xDEADBEEF after all arrays and verify that it is the same on the program exit, might help some...

I would agree about your 'ed' question, but does not Ctrl-D work just fine? Hey, this is quite standard...
As a side note/story, I used to know a girl who worked in medical sciences... Their "computer guy" told them to exit vi by pressing Ctrl-Z...
No wonder she was wondering what were all those "Your editor was killed after 4 days!" e-mail messages to her was about!:)
My favorite interview question (not that I do any interviews myself those days, since we are not hiring, but what I recommend friends of mine...;) ) for anyone who has U*IX listed in their resume together with Windows 3.1 and MS-DOS is:
How do you exit vi?
My guess that at least 50% would be gone, and we are in binary search mode, are not we?;)

P.S. I personally am an emacs person, but if they EVER had to sit at the console of a bare-bones just-out-of-the-box non-Linux server, they would've see vi set as a default PAGER and would have to figure this out...;-)

Hey! "parallelizable scientific computing"??? ASCI (used to be world fastest until a week ago) computers more or less alternate between fastest Intel and fastest IBM/Motorola/Apple processors. How comes they are 'stick with x86"?
These cubes implement the 3D mesh (in real 3D!:)), and it has too long a latency for real multiprocessor computing. When you are accessing slow device (hard drive) you can live with this latency. If you want to run computation on this network, you'll notice that your efficiency is terrible. This is why interconnects in real supercomputers are either crossbars or some kind of multistage networks, maybe meshes, but 5-7D. Try packing THAT into lego blocks!:)

This does not sound right, because they do not have the authority to interpret the law, really... Whether it is LEGAL or ILLEGAL is up to the court/judge to decide, prosecutor's office can only bring charges (if they decide to do so), but not proclaim someone innocent.

It should improve interactive performance (i.e., your mouse will start moving again:) ) when load is high. Also, running your background process nice'ed will be helpful.
You might also consider a crazy idea of having swap file on NFS -- you'll get (if your network is decent) almost the same bandwidth as you get when accessing (older) disk, but much higher latency (this will put your background process in disadvantage compared to your interactive processes).

Hmm, actually I meant using (as in actually executing) a copy of software of which you do not own a copy, but picked it up from a friend who happened to sign an EULA which later was found invalid (in parts, maybe also in whole).
The point that EULA or click-trhough license on their website is a binding contract does not seem valid. If this contract infringes on one of the basic rights it should not be legal, same as I can not legally sell myself into slavery by signing any contracts.
Another interesting question is if just that part of the contract is found invalid in court, does the contract have the provision for invalidating clauses one by one or does the whole contract become invalid?
And if the whole EULA becomes invalid, can one legally violate their license and dissiminate ("pirate") their software as much as he wants?;-)

They can not CONTROL Linux, but what that are likely to do it to release more code to be included in Linux _under_GPL_ to make their (and everyone's else) life easier.

A neat idea, but wouldn't that just migrate the problem to the NFS host? I'm too lazy to try it myself.
Sure it would, but:
interactive performace on NFS server might not be that important
it might have faster disks
and, finally, the swap hog program will slow down due to network latency, creating less load on NFS server than it would on the workstation.
Paul B.
It should improve interactive performance (i.e., your mouse will start moving again :) ) when load is high. Also, running your background process nice'ed will be helpful.
You might also consider a crazy idea of having swap file on NFS -- you'll get (if your network is decent) almost the same bandwidth as you get when accessing (older) disk, but much higher latency (this will put your background process in disadvantage compared to your interactive processes).
