But I really can't f...

As a developer, I've often downloaded and run ./configure ./make ./make install to install apps onto my Linux system. But I've never been quite clear on the best place to keep the downloaded directory. My local Desktop is the default location, but I'd like to know what the best "official" place to keep it is. Also, does it vary by di...

Hello, I've wanted to test if with multiply processes I'm able to use more than 4GB of ram on 32bit O.S (mine: Ubuntu with 1GB ram). So I've written a small program that mallocs slightly less then 1GB, and do some action on that array, and ran 5 instances of this program vie forks. The thing is, that I suspect that O.S killed 4 of them...

I'd like to allow more memory to have longer timings in my analysis. I'm running linux and using gcc. Is there a system call, or environment variable, or gcc flag, or wrapper, or someth...
I'm running a sort of "sandbox" in C on Ubuntu: it takes a program, and runs it safely under the user nobody (and intercepts signals, etc). Also, it assigns memory and time limits, and measures time and memory usage. (In case you're curious, it's for a sort of "online judge" to mark programs on test data) Currently I've adapted the safe...

Primarily I've done basic (novice level) software development on a Windows machine, but I've always had MS Visual Studio to help me step through the process of debugging. Now, however, it looks like I will be on Linux, so in order to get ready for the jump I want to make sure I have a tool/tools lined up to help me step through the co...
