It's demoralizing that we live in 2026 and a modest level of traffic is still enough to take down half the web.

Probably not with any technology; it's unlikely that fetal development and growth can happen properly in gravity much lower than 1 g.

Human colonies are not sustainable anywhere offworld.

Amazing discussion thread; thank you to all who shined a great white edifying light on the topic here.

Both were known to be Kuiper Belt objects, so it was expected there would at least be a family resemblance. I don't think anyone expected Pluto to be more active than Triton; that was certainly a surprise.

If there are planetologists reading the thread, I'd love to hear a more authorative perspective than mine!

No shade on New Horizons intended, but I was talking about the early 2000's revolution in understanding of ice moons/ocean worlds, and that preceded the Pluto flyby by a lot.

It was a valuable piece of corroborating evidence, but not shocking and unexpected in the way results from those three missions were. We had good reason to believe Pluto would look a lot like Triton, and it does.

Not true at all, the daily dose on Ganymede (which has a magnetic field of its own) is ~70 mSv/day, and Callisto is 0.1 mSv/day.

Io, meanwhile, is 35 Sv/day. Location really matters among the four Galilean moons.

Right. I said mountain to stress the importance of topography in the NM accident. The parent commenter may pat himself on the back for never flying into terrain during GPS outages in Florida, but there are factors in play in addition to his superior skills.

The highest mountain summit in Florida is 105 meters above sea level.

Thank you! I realize people have subscription fatigue, and that on this site in particular there's a culture of expecting to read the full text of everything for free. So I try to make the previews substantive enough for people to participate in discussion whether or not they sign up.

I do feel like the free sample guy at Costco, confident that once people try the cube of summer sausage on a toothpick, they'll want to buy the whole thing. But I sure appreciate someone else saying it!

A lot of the work was done to a design point of 0.25 seconds, and Dyson's book says the issue there wasn't the blast clearing, but just being able to move the machinery fast enough. I kind of share your puzzlement; I can see the blast clearing this quickly in space (the debris moves at tens of thousands of km/sec) but not in the atmosphere.

New comment by idlewords in "Pinboard's DNS registration has expired"

idlewords — Mon, 15 Jun 2026 21:24:17 +0000

Hi everyone,

The domain should be back up within the next few hours.

I had the domain set on auto-renew but unfortunately something went wrong, and I didn't get an email from the registrar about it (or it got misrouted to spam).

I've renewed the registration but it seems to be taking a while to propagate back to the .IN servers. An interim measure is setting an /etc/hosts record for pinboard.in to 64.62.134.190.

My sincere apologies for the outage. The TLS cert for Pinboard renews in October, and in my mind I thought the domain renewed at that time as well, or I would have paid closer attention. Irked at my own carelessness here.

It's fine to dump sewage overboard if you're far enough from shore. Cruise ships treat it to some extent, but ultimately it all becomes fish food.

There's a nice paper on this, ICES-2018-123 "Dimethylsilanediol (DMSD) Source Assessment and Mitigation on ISS: Estimated Contributions from Personal Hygiene Products Containing Volatile Methyl Siloxanes (VMS)". The upshot is more than half of the siloxane burden on ISS comes from God knows where (packaging, plastics, machinery, you name it).
