[bad designed hardware]
I've a colleague that has a Mac G4, and after a day of normal work (such as wordprocessing) he can do fried eggs on its back side. I think this ability to do fried eggs has nothing to do with R. Alberto

Dear R Gang:
Dear guy,
I have a Macintosh G4 powerbook, running OS 9.2. Last week I
ran a statistical analysis program that I wrote in R for two days
continuously. The program does repeated intensive computations on a
large data set.
The program completed its task successfully, but during the
process I noted that the computer seemed to be running unusually hot.
Shortly after the program stopped, something unrepairable happened to
the computer. I don't know the cause of the problem yet, and won't
find out until Monday or Tuesday, but it seems to involve the hard
drive - Norton Disk Doctor cannot fix it, nor can I restore the
original software to the hard drive.
The computer breakdown may of course be unrelated to my use
of R, but I am concerned that running the computer so intensively may
have caused the problem. Has anyboody run into a similar problem
using R on a G4 machine? I have also been running R on a G3 I-Book,
using the same operating system, though not the same program, and I
have had no problems.
You ran calculations and so you used your CPU extraordinary, so it's reasonable that it gets warmer than in other circumstances. If the cooling system doesn't work sufficiently, that might cause damages. In that case your hardware was not designed properly (e.g. to cool the 100% used CPU).
