Where did you get those facts? The company's web site still lists Gil
Schwed as the CEO and Eyal Desheh as their CFO, both were at that

I want to appologize about my comments about Checkpoint.
I looked at a stock page for Checkpoint Systems, inc, which is NOT!!!

Yes, I am aware of all of the above except memfetch (I did not remember
the names of dumpmem, but I did attend your lecture at the time).

When I did this in the past, it was always intimately tied to what the

I have no direct answer to your question. Oom-killer should be triggered in a
memory emergency, and not when there's enough free memory space.
Some notes though:
A. oom killer doesn't randomly choose a process to kill.. I described the
algorithm for choosing a candidate for killing in:

Interesting... I assume this is without kernel support (e.g., UML's
SKAs patches).
I wouldn't be able to call it "user space" if it was.
I should point out that, ptrace being ptrace,

I've used scons for a small project with a complex build environment. We
were very unhappy with the results.
I found its design and API quite deficient. Additionally, we've encountered
quite a few major bugs that we had to work around.
Make, while deficient in its own right, at least works as expec

There is surely a profit and a lot of fun around here, but indeed there was a
