Error'd: Relatively Speaking

Amateur physicist B.J. is going on vacation, but he likes to plan things right down to the zeptosecond."Assume the flight accelerates at a constant speed for the first half of the flight, and decelerates at the same rate for the second half. 1) What speed does the plane need to reach to have that level of time dilation? 2) What is the distance between the airports?"

Contrarily,Eddie R. was tired of vacation so got a new job,but right away he's having second thoughts."Doing my onboarding, but they seem to have trouble with the idea of optional."

"Forget UTF-8! Have you heard about the new, hot encoding standard for 2024?!"exclaimed Daniel, kvetching"Well, if you haven't then Gravity Forms co. is going tochange your mind: URLEncode everything now! Specially ifyou need to display some diacritics on your website. Throwaway the old, forgotten UTF-8. Be a cool guy, just usethat urlencode!"

Immediately afterward, Daniel also sent us another goodexample, this time from Hetzner. He complains "Hetzner says the value is invalid. Of course they won't say what is or isn't allowed. It wasn't the slash character, it was... a character with diacritics! Hetzner is clearly using US-ASCII created in 1960's."

Finally this week, we pulled something out of the archive fromBoule de Berlinwho wrote "Telekom, the biggest German ISP, shows emailaddress validation is hard. They use a regex that limitsthe TLD part of an email address to 4 chars." Old but timeless.
