One place where singleton tuples used to be common is with the old "%"-formatting, specifically in the case where there is a single argument and its value might be a tuple: x = (1,2,3) #print("the value of x is %s&q

[Edit: The gibberish sentence "A variation moving up is also allowed." was meant to say "A variation of this solution can be used to solve the case where moving up is also allowed."]

There is a mistake in the article's statement of the problem. It says > the possible moves are going right, down or up by one but the actual problem ( https://adventofcode.com/2021/day/15 ) allows moving i

The unmount was just for verification. The tool is clearly intended to be used without unmounting the disk at any point. Repeatedly copying until there are no new changes would produce a consistent image (if it terminates -- it requires the

That's a valid concern, but in this case it won't cause problems -- grep exits with 0 if a line was selected; in the case of `grep -v grep` that means there was a line without "grep", which is what we want. (Also @thewak

pgrep is great, but note that you can still encounter this problem if you run pgrep in parallel -- it will never match its own process, but it will match other pgrep processes. So for example if you have a script that uses `pgrep -f ban

That won't work because sshd runs the command using the user's login shell. From https://man.openbsd.org/sshd#LOGIN_PROCESS : > When a user successfully logs in, sshd does the following: > ... > 9. Ru

For some reason I thought this was a standard feature of tar, and was surprised when it didn't work. It turns out that GNU tar supports extraction of concatenated tarballs, but it requires the --ignore-zeros (-i) option: > Normally,

I love GitLab, and Pages access control is a great feature, but I think this was rolled out very poorly. <rant> The access level is "Only Project Members" by default for private projects, which I consider a breaking change b
