Can someone please point out some books or online resources which explain in detail and at an advanced level the task management features of x86? I'm specifically interested in understanding the relationship between x86 hardware and the OS (POSIX style) when an interrupt or context switch occurs. Intel manuals are very confusing and I ca...

Is there some resource editor for windows executables I could run from a CentOS box? Something like Resource hacker, that allows to update icon and fileversion. But I don't want to install wine because it's not my server and I want to change much. I would like to run it from a .py script so anything that works from a terminal will do....

I'm using SDL_Image to display a JPEG on screen and having some issues with the resolution it's being displayed at. I understand that if I pass 0 to width, height and bits when calling SDL_SetVideoMode that SDL takes the current modes values, however these seem to be wrong in my case. I'm running this on an embedded linux system with a...
I've seen the usage of exit status 3 in several python scripts that restart processes. As far as I know the convention is only about 0 and "not 0" on Unix/Linux. Is there a convention defining other values like 3. ...

I have a footpedal (see altoedge.com) and fortunately there is a software for using it under linux (see http://code.google.com/p/footpedal/). The author of that software already solved an issue for me (see issues there), but there is no option to ask simpler questions. Unfortunately prior to use the software I have to change the device...
I've got a web server running Ubutu 10.04 and Apache2 and PHP. When I upload a file to the server through PHP, it creates it with 'rwxr-xr-x' and 'www-data www-data' as the user and group. I've added my 'administrator' account to the 'www-data' group. However, when I log in to my server through SSH and try and delete one of the files ...

Most command-line programs just operate on one line at a time. Can I use a common command-line utility (echo, sed, awk, etc) to concatenate every set of two lines, or would I need to write a script/program from scratch to do this? $ cat myFile line 1 line 2 line 3 line 4 $ cat myFile | __somecommand__ line 1line 2 line 3line 4 ...

Hi all, Apparently this is almost a duplicate of "Bad pipe filedescriptor when reading from stdin in python - Stack Overflow"; however, I believe this case is slightly more complicated (and it is not Windows specific, as the conclusion of that thread was). I'm currently trying to experiment with a simple script in Python: I'd like to...
