Hi, I'm looking on the Linux IA-32 memory model processes see and have a simple question to it. What is there in the grey areas in the picture? Or is it just to show start and end of the memory? So, do text start at 0x0 and stack start at 0xFFFFFFFF? Best regards, Lasse Espeholt ...
I installed NetBeans 6.8 on Linux (Mint, based on Ubuntu 9.10) and I can see that font rendering is very weird. Fonts in NetBeans are just so thin unlike any other program, be it gEdit, Eclipse, Firefox, or whatever. Does anyone know if it's possible to make fonts in NetBeans look bolder? Bonus question: AFAIK both Eclipse and NetBean...

Is there any way I can make gdb run in the background (via quiet or batch mode?), follow children (as my server is a daemon and detaches from the main PID) and automatically dump the core and the backtrace (to a designated file) once ...

The old folder format (ones that need to be changed) was clientcode_jobnumberjobname. The new format is clientcode_jobnumber_jobname. We basically need to change the old folder names by adding the extra underscore to th...

I've got a pile of code that builds in many places. I just turned on the build on Ubuntu 8.0.4 LTS with gcc 4.2 and ccache, and received for my trouble an error from the linker that I've never seen before. Googling leads to suggestions that I've got a shared object built with naked ld involved, but, in fact, I do not. What do I have? /u...

I'm writing an app that heavily uses OpenGL; either on the Mac or on Linux. I've heard of various rumors of Apple having buggy OpenGL drivers (and a reluctance to fix them). Can anyone confirm/deny this? If you've developed on OpenGL on both Mac and Linux, how do they compare? Thanks! ...
