You'll be sorry. I'm recording all of this in my
Src/beowulf_book/List_Ideas/Space file. One day Cows In Space (as told
by a certain GC:-) will be on the tongues of all humans on the
planet...or at least all of those interested in building clusters.
It's pretty clear that there is a chapter in all this, but I've spent
some 24 out of the last 36 hours rewriting the brahma website in php.
That (by the way) is almost done -- people who have used
in the past might check it out again at
and comment if they so desire. When my energy banks recharge, perhaps
I'll tackle the Cows. So to speak...
