The core of the problem is game-theoretic in nature, a coordination problem, related in some ways to the tragedy of the commons. Unless one of the entities involved goes out of their way at personal loss to fix the issue, all agents are op

On the one hand, this is a really neat hack. On the other hand, given the current situation with cars, pollution in cities (air quality, noise-level etc), global warming, I would personally think twice before doing something that would make

I was once thinking of implementing such an online judge. Looking through the existing implementations, most restrict the syscalls available to the untrusted process, and run in a chroot. On freebsd, you'd use something like capsicum.

Actually, that is not entirely true. The monad bind operator introduces a data dependency which is responsible for the sequencing itself, not the actual implementation of the bind (i.e. it is a result of the type of the bind). But I do agre

It doesn't make any sense at all to me either. Because of the difference in specific heat and heat conductivity of water vs air, an animal that can sleep under-water (even whilst alternating the sleeping part of their brain), surly doe

It's slow because of its design, i.e. spawning a new process for each request; so it's not because of the OS.

This makes me hope that maybe all those chipmakers will finally move on from that extremely long-lived 28nm node. It has been heavily used since 2011-2012 and even companies like Qualcomm have been using it as recently as last year in the l

Other than HaikuOS, I can't think of any other real-world kernel written in C++. Linux, all BSDs, Windows NT, Hurd are all C. I'm not sure but I think XNU is C as well (the wiki lists it as C/C++).

It has little to do with epistemology. The main cause for human conflicts is the fact that we are playing zero-sum games. Humans are constantly fighting/jockeying for status, acquiring resources for themselves, and simply getting ahead
