Sure, strtok is a terrible misfeature, a relic of ancient times, but it's plainly the heritage of C, not C++ (just like e.g. strcpy). The C++ problems are things like braced initialization list having different meaning depending on the set of available constructors, or the significantly non-zero cost of various abstractions, caused by strange backward-compatible limitations of the standard/ABI definitions, or the distinctness of vector<bool> etc.

Beware the DWIM!

In one notorious incident, Warren added a DWIM feature to the command interpreter used at Xerox PARC. One day another hacker there typed delete *$ to free up some disk space. (The editor there named backup files by appending $ to the original file name, so he was trying to delete any backup files left over from old editing sessions.) It happened that there weren't any editor backup files, so DWIM helpfully reported *$ not found, assuming you meant 'delete *'. It then started to delete all the files on the disk!

It's not as easy as it sounds, sometimes the screens are all wrong!! https://xkcd.com/722/

Well... unless you measure the number of [milli]seconds using something like time_t, which lies because of leap seconds. I.e. even such a seemingly simple interface, in fact, includes a calendar.

Yeah, that's why unlocalize.com exists (or... existed? Dunno, seems down from here!) Or you can have used the official Microsoft Language Portal... until they removed it and replaced it with the worse https://learn.microsoft.com/en-us/globalization/reference/microsoft-language-resources (but it's still usable, I guess...)

uMatrix browser extension. It has been marked archived by Gorhill, last release is two years old, you are supposed to just use uBlock [Origin]. However, it still (luckily) works fine and is exactly what I want. (Sure, I won't install this for my parents.) The GUI to simply choose what you want the site to be allowed to do is perfect.
