Auto executable python file without opening from terminal?
Sorry if this is on the wrong site ( maybe superuser ) but I'm trying to make my python.py file executable so I can click on it and it automatically does its thing, without me specifying it to open in the terminal by that default prompt, and I already have 'chmod +x' for its permissions.

C++ Executable distribution strategy
Recently I have asked a question about what I should use to create self-contained executables that would be deployed under a number of Linux distribution. I got very scared at first, but after reading about C++ a little, I managed to get the first version of my executable going. After a day full of joy, I just hit the wall again with an...

Grant capabilities to a running process
An already running process needs a privileged instruction, like using the SO_RCVBUFFORCE socket option. This process is running as a normal user process.

Hi I want to programatically [in C] calculate CPU usage % for a given process ID in Linux. How can we get the realtime CPU usage % for a given process ??

Deploy repository code to multiple machines at once
My question is: How do you guys deploy the same code from whatever [D]VCS you use on multiple machines? Do you have an automated deployment system and if so what's that? Is it built in-house? Are there out there any tools that can do this automatically? I am asking because I am pretty bored updating up to 20 machines every time I make s...

Erlang: daemon 'init.d' script fails to start
I have a python script which manages an Erlang daemon. Everything works fine when used through a shell once the system is initialized. Now, when I included the same script under "/etc/init.d" and with the symlinks properly set in "/etc/rcX.d", the python script still works but my Erlang daemon fails to start and leaves no discernible tr...
fcntl substitute on Windows
I received a Python project (which happens to be a Django project, if that matters,) that uses the fcntl module from the standard library, which seems to be available only on Linux. When I try to run it on my Windows machine, it stops with an ImportError, because this module does not exist here. Is there any way for me to make a small c...

Linux/Unix Experience
When I look at job descriptions for Google, Amazon etc, they all require C++ and Linux/Unix experience. Could someone please define what this usually means in the context of job qualifications?

On a Linux desktop (RHEL4) I want to extract a range of bytes (typically less than 1000) from within a large file (>1 Gig). I know the offset into the file and the size of the chunk.
