comment Why double ampersand chained conditions runs in background together the last one?
Yeah, but it's a subshell whose PID and job no. are known to the current shell: (background-job&) leaves it completely detached

Does the user have an encrypted home directory? If so, it will be unmounted and unavailable when logged off.

comment Process Files to create a new file
What values? You haven't shown even a single sample line of your three files, just said that the first file contains commas, and two 24-hour timestamps. Is there anything else in there? What order are the columns? Is file 2 a single integer value, or something else? What should file 3 look like?

comment What's limiting my CPU usage in forked processes?
Oh, and if you're running top, can you see something else on CPU that would prevent your processes running? Does the priority (PR) value change over time?

comment What's limiting my CPU usage in forked processes?
It might also help to see the output of ulimit -a from the shell where you start your processes (or the equivalent limit or whatever if you're not using bash)

comment Why is apt filling up disk space that `apt-get clean` frees?
What makes you think apt is filling your disk with logging? It's filling your disk with packages, and they must have come from somewhere. See help.ubuntu.com/community/AptGet/Howto#Maintenance_commands

What are you using to measure free memory, and what else does it tell you? Oh, and how much swap do you have configured?

comment Expand ~, . and `..`
For example, type ls -a and you'll see the . and .. directories. The only reason they're not usually shown is that anything beginning with . is hidden by default.

comment Is it Unix timestamp incremental?
But it isn't necessarily unique, if you could retry within the same second (unless you're using Python's fractional time, which is probably fine).

comment How can I enable mouse in Vim?
Assuming you're running VIM in a terminal (and not using the GUI by running gvim or vim -g), showing the result of echo $TERM might help.
