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.
In the same way that every breath you take contains at least one atom-or-molecule of Caesar's last breath, every sip you take contains at least one atom-or-molecule of every cruise ship waste jettison. (Assuming sufficient worldwide diffusion time.)
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).
> The main sources of VMS were determined to be antiperspirants ... skin lotions ... wipes ... and hair conditioner. Several siloxanes-free options are available for [these products]. These products are now being assessed for crew member use in future increments.
From the blog:
> At present the agency is testing a new filtration system to put in front of the heat exchangers, to try to protect them, and continuing to try to cut down on siloxanes at the source level. There are probably people at NASA now whose entire career has been built on siloxane control.
Why wasn't the result to simply ban siloxane-containing cosmetics and wipes? The cosmetics are up to the individual astronaut, which is a little crazy, but the wipes are provided by NASA, and they're still using siloxane-bearing wipes, which shortens the life of their water systems and costs crazy amounts of money.
You can't just replace stuff in a sealed environment - if the new stuff is better in one way it might be worse than others. Gotta do the qualification work - remember they're drinking piss up there.

I would assume there is an approval process in place and alternatives have to go through this process before they can be sent up. It might take months or years for approval.
I thought so too, but the phosphine signal turns out to be small but real. What everyone involved in the back and forth debate over it agrees on is the need to send better sensors.
It's not an absurd question. The threshold value is the one that breaks surface tension and effectively pulls waste away from the body. It will be more than a few hundredths g but less than 1g.
Unfortunately we have basically no data on the effects of partial gravity, in this context or any other. We can try flying partial-gravity parabolas in aircraft and simulate a Martian toilet the same way they tested the design for Skylab; I don't think this experiment has been done.
