I want my website to join some webcam recordings in FLV files (like this one). This needs to be done on Linux without user input. How do I do this? For simplicity's sake, I'll use the same flv as both inputs in hope of getting a flv that plays the same thing twice in a row. That should be easy enough, right? There's even a full code exa...
Hey all, my Computational Science course this semester is entirely in Java. I was wondering if there was a good/preferred set of tools to use in ubuntu.

What is the best way to setup one linux box to listen on its serial port for incoming connections? I've done a lot of googling but I can't find the right combination of commands to actually get them to talk!

Hello ! Besides the LD_PRELOAD trick , and Linux Kernel Modules that replace a certain syscall with one provided by you , is there any possibility to intercept a syscall ( open for example ) , so that it first goes through your function , before it reaches the actual open ? ...

I'm using TextMate on Mac OS X, which I am very happy with, but I would also like a nice editor on my Ubuntu box. So I have been looking for something like TextMate, which is very simplistic in its interface but very powerful beneath that surface, with a plugin system and all. Is there any similar editor for Linux? ...

I have several nested X Windows - let's say - a scrollable window within a scrollable window (see the example below). In such case the main window contains (at least) the major scroll bars and the (major) drawing area they control. This drawing area on its turn contains (at least) a scrollable window batch - a (minor) main window, contai...
I've got a C++ program that uses SQLite. I want to store the SQL queries in a separate file -- a plain-text file, not a source code file -- but embed that file in the executable file like a resource. (This has to run on Linux, so I can't store it as an actual resource as far as I know, though that would be perfect if it were for Windows...
