I am a curious person who always likes to learn more. I like solving puzzles and I like working with computers. Which means I enjoy some of the more complex questions on this site, as well as the answers which go into details and explain all facets.

comment How to limit a user's RAM on Ubuntu?
The answer you are looking for is called ulimit. There is already a post about that here on this site.

comment Stuck in login loop after editing /etc/profile
It is a bit late now, but the next time you do similar things: do not log out. Switch to a different TTY and test if your login changes work. Only then consider logging out.

comment I don't have writing access to a subdirectory in /
Just as an added note to the OP: Do not 'fix' this by adding the 'w' to the others permissions.

comment Not able to change default group for user with `sudo usermod -g`
Or log in on another terminal to check if all still works before you log out in your old one.

comment What do you do to scan with 600 dpi while maintaing a small output file?
Which file type did it save as? Just as a TIFF with the extension.jpeg or in actual JFIF format? (Use the command file file_to_test.jpeg_.

comment CPU is free, yet bash script not utilizing all CPU resources
You are right. The shell does not start a full new shell. Instead it runs static int execute_in_subshell (command, asynchronous, pipe_in, pipe_out, fds_to_close) which has the clear comment "/* If this is a simple command, tell execute_disk_command that it might be able to get away without forking and simply exec."... I'll delete my erronious comment/

If you are logged in as root then you would not need the sudo part.

comment dd vs cat — is dd still relevant these days?
Can I interest you in copying the whole post here on Super User so we can point other posts to it as a duplicate. (Can't do that cross SE sites).

comment How much swap space should I use?
True. But swap twice RAM is a thing of the past when we still used swap. These days both linux and windows use paging. We might still call it a swapfile, but that is just habit and no longer reflect the underlying truth.

comment Support for old network cards in lightweight distros?
OP: Why not check which drivers you need of the card and it there are drivers for it in a modern kernel? (Or if they have been removed after there no longer was a maintainer for that driver after API changes). Once you know it works with a kernel (I almost would say 'with linux') then you can use it. The distribution (the GNU/userland part) is irrelevant here.

comment Kill process spawned by ssh when ssh dies
I assumes that when ssh dies that your shell also dies. You can configure your shell to send a signal -1 (SIGHUP) when it terminates. (shopt -s huponexit). Can you test if this works for you?

comment Check a range of IP addresses to see if a host is active
Just to add a note: Your example seems to assume a /24 subnet (which used to be called class C, but in the last decades we changed to CIDR). Thus your example will not allow you to test a /25, a /23 or any other subnet which netmask is not a multiple of 8. That might suffice for you, but it really is something you need to be aware off.
