in this example "in" is also part of the syntax, not the metasytax, so format it like the others

comment How did `git pull` eat my homework?
@Volker no. The only time I mess with those values is with vcsh managed repos of which this is not one. Those env vars would have been per default git behavior in this scenario.

comment Why is ImageMagick's `compare` command so slow and is there an alternative?
@StéphaneChazelas Maybe it is (I wasn't aware of that project) but can I feed motion arbitrary static image frames as opposed to a direct video feed and and still have it do its job? My morbid curiosity also wants to know exactly what could hog 25 seconds of CPU cycles across 4 cores analyzing a pair of images with a grand total of 48 pixels between them (6x4*2).

comment Using localectl on Arch, Failed to issue method call: Invalid Locale data
This should not be closed as "cannot be reproduced". I had the same problem and arrived here via search and found the solution.

comment How can I delete all lines in a file using vi?
Your shell syntax is dependent on configuration for some shells. Both bash and zsh (zsh by default) interactive shells can wait for input on STDIN after receiving that command and an additional <CTRL>+D is necessary to actually clear the file. The ability to run that is also dependent on CLOBBER settings. >| test.txt < /dev/null is somewhat more robust as it will always clobber the file and avoid waiting for input on interactive terminals.

comment Linux solution for schools?
Good question, but I'm very much afraid there isn't a silver bullet in that sector. This is one of the edges where the whole distro scene starts to fall apart. And sadly most of the institutions that put together their own solutions don't end up generalizing them to be put back in the OSS space.
