Shoutout to the old-school diver who showed me a better way to handle my umbilical

For years, I just let my umbilical drag behind me on the bottom, which worked until I got it snagged on a wreck in Lake Michigan last fall. An old-timer on the boat saw me struggling and said, 'Kid, you're making it hard on yourself.' He showed me how to use a simple carabiner and a short length of rope to clip the umbilical to my weight belt, keeping it up off the deck and giving me way more control. I've been doing it that way for six months now and haven't had a single tangle. Anyone else have a simple trick like that for umbilical management?

Found a city building code that makes no sense for fire-rated walls

I was looking up rules for a job in Phoenix last week and saw they require a full 5/8 inch board on both sides of a metal stud wall for a one-hour rating. Everywhere else I've worked, you can get that with 1/2 inch on one side and 5/8 on the other. It's right there in their 2021 code addendum PDF. That extra board adds cost and weight for no real safety gain, doesn't it? Has anyone else run into this and just had to eat the extra material cost?

I keep seeing people ask questions in the wrong way here... it makes a big difference.

Can we talk about how Signal's disappearing messages saved my group chat last month?

Honestly, my friend in Berlin runs a small book club that sometimes discusses banned authors. Ngl, their old WhatsApp group got flagged and shut down for 'suspicious activity' after they shared a PDF. I told them to switch to Signal and set messages to vanish after 24 hours. It's been 6 weeks now with zero issues, and they feel safe talking again. Has anyone else found a specific app feature that actually made a difference for a group under pressure?
