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 NASA disasters where the organization learns lessons, becomes more careful... and then standards potentially slip.

from the docs:

"Wealthfolio does not currently support integration with online brokers or aggregators. Data must be imported from CSV files or by manually entering transactions."

So data has to be imported since the start then I'm assuming, like a complete ledger? Otherwise how would we know the complete list and the value of the investments over time. Won't that get out of sync with the ground truth (what's in the account) over time?

You can also start from one snapshot of your current holdings and just add transactions as you go to build the timeline.

"store contact information and related notes for small and medium businesses"

Most likely translation: it affected the Google SMB sales team's Salesforce instance

My understanding is that the Cloud org uses Salesforce, the rest of Google uses a self-developed solution.

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 (though admittedly, I don't use it often in suburbia)

(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 scrubber.

There's nothing special about a submarine that makes CO2 somehow different than anywhere else.

I recall this study and maybe another one:

https://pubmed.ncbi.nlm.nih.gov/29789085/

I’m definitely not an expert.

What if you're low on sorbent and can't turn on another scrubber ?

I wonder if sorbent quantity correlates with performance

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.)

I got to know Quentin Stafford-Fraser a bit when I was at Cambridge. He's a really down-to-earth guy who was working on all sorts of interesting projects.

He's got more details on the whole Trojan Room Coffee Pot experience on his blog: https://quentinsf.com/coffeepot/

I also recently got to know him, and can confirm the above! We got to know each other because of our interest in small sailing boats.

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!)

+1 for that book. I’m surprised no one has yet tried to work it into a movie or at least a made-for-TV movie.

IIRC (its been decades I think) that book was pretty critical of the unions working at the plant. Good luck getting that made in today's environment.

I feel that way about many of Michael Crichtons books.

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.
