pip: inconsistent permissions issues | 11,169,137 | 13 | 16 | 11,217 | 0 | python,centos,pip,python-module | When you run a command using sudo, it will preserve the users umask. pip just installs files, it doesn't change access rights, so you'll end up with the files having the access rights set conforming to the current user's umask, which may be owner-readable only (0077) and therefore readable by root only.

Fabric equivalent of try finally | 11,497,518 | 0 | 5 | 1,088 | 0 | python,fabric | You could always use the new execute() and wrap that in a try/except or just look at the return codes from your run()s. | 0 | 1 | 0 | 0 | 2012-06-22T18:39:00.000 | 2 | 0 | false | 11,162,214 | 1 | 0 | 0 | 1 | In the eventuality that Fabric exits cleanly or not, I need to execute a bunch of clean-up tasks (mostly delete temp files and folders).

How can I detect my RAM free and total space in Python? | 11,170,901 | 1 | 0 | 186 | 0 | linux,python-2.7 | You are asking for a number that is nearly impossible to calculate and has very little value.
Any Linux system that is running for an amount of time will have hardly any 'free' ram available. Just cat /proc/meminfo - the MemFree entry is usually in order of just a few megabytes.
So, where did that memory go?

Of course you never need a package manager, you can just get all the programs, or libraries in case of pip and Pypi yourself.
