It looks like the account where this repo was published was the one used by Google Workspace DevRel? (And that’s the team this guy worked on.) That makes this quite a bit different situation than publishing the repo on a personal account.

Data points that worry me: 02/1967 - Apollo 1 fire 01/1986 - Challenger disaster (19 yrs later) 02/2003 - Columbia disaster (17 yrs later) It's been 23 years since Columbia, and there seems to be a 20-ish year rhythm to

I was visiting Yosemite a year-ish ago and a guide recommended this app and it was fantastic. My kids also loved getting the real-time info on what they were hearing, and trying to spot the various kinds of birds. Strongly recommend it (th

(Former submariner here.) Elevated CO2 in submarines absolutely impairs performance. One example: there was a guy on my boat who got migraines when CO2 got too high - he was useless. Luckily the fix is simple - just turn on another CO2 sc

I used to row in London on the Thames, and yeah, the tides are nuts. The river rises seven meters in the span of about 3-4 hours. (It takes about 7-8 hours to flow out.)

Sounds like the plot of Michael Crichton's book "Airframe" - https://en.wikipedia.org/wiki/Airframe_(novel) (Though in this case the parts were found before anyone was hurt/killed!)

It's unlikely to go offline. They've got the funding to keep it open, they're just waiting on federal acceptance of their continuation plans.

The main thing is that you need to be moving at least a few knots in order for your control surfaces (rudder, forward planes, stern planes) to work.

antenna buoys on cables? No. But there are VLF antennas that Ohio-class submarines have to receive low-data-rate comms while submerged. Any reasonable communications have to be made while at periscope depth. (Which is subtly different than

Ohio-class submarines (the ones that carry missiles): when they're "on station" they're just tooling around staying as quiet as they can. There's a relevant phrase for them: "Three knots to nowhere" Los An

Active sonar (where a device sends a pulse of energy & listens to replies) can impact marine life. Passive sonar (where you just listen to acoustic energy in the water) is used by submarines and surface ships to find submarines. With b

(Former US submariner) Yes, and no. Yes- the US has maps with higher-resolution data on water depth around the world than what's commercially available. No - those maps aren't perfect. Some areas are extraordinarily well-mapped,

Ah, interesting. So it sounds like they haven't updated the data in ages, either. What I always loved about this site is that Google made it SUPER-easy to visualize just how good (or not) any given roof was for solar. At the time it

That article is only about the lead-generation part of Project Sunroof being shut down. Which makes a ton of sense - it was likely not generating much revenue, but managing a program like that can suck up a ton of time in managing those re

I loved my Newton. I loved it so much that even when it was stolen out of my car in ~2003, I got a MessagePad 2100 off of eBay to replace it. It was only when the iPhone came out that someone was able to pry my Newton out of my hands.
