the "what" is interesting on interfaces or when you generate documentation with some tool like sphinx or javadoc.
the "why" is interesting when you are somewhere inside a class or function and do something in a "strange" way, to work around a quirk in the codebase or something like that, or when you employ optimizations that make the code harder to read or atleast less obvious why somethings are done.
good Tester.
If something stupid can be done, it will be done.
just remember that ich_iel has a lot of fun with literal translations of english words which can lead to very weird german.
Nur erinnere, dass ich_iel ein Los des Spaßes mit literarischen Übersetzungen von englischen Wörtern hat, was zu seltsamen Deutsch bleien kann.
for receipts and such paperless ngx is good. that won't track your repairs or inform of you of likely maintenance problems, but that and a spread sheet sounds like a good start.
there is no "undefined" in java. this would either be a map containing the key value pair ("name", null) or it would be mapped to an object of some class with an attribute "name" which can hold a null value. in any case {} wont equal {"name":null}.
look into local dns servers if you want multiple machines to use your local domains if you only want a single windows or linux (and probably mac) computer to use the domain to access a specific local ip an entry in your etc/hosts file would be enough
https://github.com/docker-mailserver/docker-mailserver should be able to do it.
if i remember this in 6 weeks i'll check the setup at work.
i've only read about rust, but is there a way to influence those automatic implementations?
equality for example could be that somethings literally point to the same thing in memory, or it could be that two structs have only values that are equal to each other
