Hi, Although having a little experience, I am still confused with the question of whether it is necessary to install an application and/or build a C++ program or C++ library under Network File System shared by machines, which have different Linux version (e.g. CentOS release 4.7, Ubuntu 8.10), possibly different bit (e.g. 32-bit, 64-bit)...

Hi there, I am playing around with linux network programming and I wrote a little client server app which bounces a small message between a client and a server process and measures the round trip time.

Problem is that my netbook is pretty low scale - it's one of the first EEE pcs and right now it is supposedly "overc...

I'm looking for [free] server software to store hierarchal data efficiently. My key challenge is that an object or group of objects almost always has 2 "parents" and one or both parents can have different connections with other parents, and those descendants must remain distinct from the common parent's other descendants.

Every cluster of computers I've encountered suffers from the same problem: its software is outdated. Naturally, one has the ability as a user to install everything from source in the home directory. I was wondering if there are any tools that would allow one to install and update software within home directory the same way package manage...

When the background processes are complete they ...
