I'm attempting to build mercurial 1.3.1. I've attempted this thus far on my Mac OS X machine and on a Linux Ubuntu virtual machine that I'm running. I keep getting errors while running the make.

On Linux I am used to using mkpasswd to generate random passwords to use, on OS X however I don't have this command. Instead of sshing in to my vps every time, I wanted to re implement it using Java. What I have done is pick at random 4 lower case letters, 2 upper case letters, 2 symbols (/ . , etc) and 2 numbers. Then I create a vector...

I found in IOStat, that some part of my application is writing extensively, but I don't know which process it is and what files it is writing to. In Vista there is a tool fo that which shows the files that have been active in the last 30 Seconds. Is there something similar for Linux? ...

I am stuck with that task. I've written svn post-commit hook, that should update working copy on server, if something was changed. But seems to be it doesn't have permissions on that folder, but I've set them to allow everybody to write and read there.

I have a small app written in C designed to run on Linux. Part of the app accepts user-input from the keyboard, and it uses non-canonical terminal mode so that it can respond to each keystroke. The section of code that accepts input is a simple function which is called repeatedly in a loop: char get_input() { char c = 0; int res =...

I'm looking for a way to read specific files from a rar archive into memory. Specifically they are a collection of numbered image files (I'm writing a comic reader). While I can simply unrar these files and load them as needed (deleting them when done), I'd prefer to avoid that if possible. That all said, I'd prefer a solution that's ...

Hi, When I write gnome-terminal --tab at the terminal, I expect it to open a new tab in the same terminal window. But it opens a new window instead. I found out that its intention is to open a new tab in a new window, i.e., if I write gnome-terminal --tab --tab it will open a new window with two tabs. So, the question is...
I have a long running process which monitors the system and prints periodic logs. If I let it run for longer than 10-15 minutes, it exits with a message saying: Too many open files. The program is setup using real time timer_create() and timer_settime() which raise a SIGUSR1 every 2 seconds. In the handler, there is one fork()-exec() in...
