!rant but nightly thoughts about wrecking clients that won't pay

If you're building something for a client for money, think of a killswitch.

If it requires internet anyway and you have a webserver, do something similar to what the killswitch of WannaCrypt was (but rather checking for a file on the webserver for existing/non-existing). If the client won't pay, kill the application. If the client pays, maybe even deliver a version without killswitch later (as a "bugfix")

If it is some offline project, you can check for a date (payment due date?) and also check for date/time manipulation on the system itself, and disable the killswitch via a "bugfix" version later just like above.

If clients pay, they don't have trouble. Else, they do.

Who here agrees that every language framework should have moment.js oit of the box. Or at least a standardized way of doing it.

Timecalculations and Datetime manipulation from UTC to locale where locale can be anything are by itself annoying but Javas Date and Calendar APIs always make me feel like "Seriously?! Fuck you! What do you want from me?! "

Argh....
Wasting so much time right now to get a fairly easy app built as showcase for new customers and continue with my life!
