April Showers

"RFC 1738 (and 3986) disagree" and so does Daniel D. "Reddit API has some weird app creation going on with lots of recently migrated and undocumented stuff. But having redirect URL set to localhost (or 127.0.0.1) usually works. Well, if you don't disagree with Sir Tim Berners-Lee about what URL is. Which Reddit does. hostnumber = digits "." digits "." digits "." digits". I'd file this one with all the websites that try to perform validation on email addresses, and get it wrong.

Turning Thirty

by Remy Porter in Feature Articles on 2026-04-21

Eric O worked for a medical device company. The medical device industry moves slowly, relative to other technical industries. Medical science and safety have their own cadence, and at a certain point, iterating faster doesn't matter much.

Eric was working on a new feature on a system that had been in use for thirteen years. This new feature interacted with a database which stored information about racks of test tubes, and Eric's tests meant creating several entries for racks of test tubes. And that's when Eric discovered that the database only allowed thirty racks. Add any more, it would just roll right back over to one.

Good Etiquette

by Lyle Seaman in Error'd on 2026-04-17

It's time again for a reader special, and once again it's all The Beast In Black (there must be a story to that nick, no?).

Nona writes: "this is the beginning of a 2100 line function."

That's bad. Nona didn't send us the entire JavaScript function, but sent us just the three early lines, which definitely raise concerns:

by Remy Porter in CodeSOD on 2026-04-15

Candice (previously) has another WTF to share for us.

We're going to start by just looking at one fragment of a class defined in this C++ code: TLAflaList.
