Ammonia is no greenhouse gas, it has a GWP of zero. Burning ammonia produces N2O, which is a potent greenhouse gas, and NOx, which is an air pollutant. But these can be taken care of by scrubbers, and are irrelevant if you ship ammonia for

I feel there are some fundamental misconceptions about signatures that are baked into many of these older standards. There have been similar attacks on XML signatures, email signatures and PDF files (with some overlapping authors). It usual

The point is: Even though WebPKI isn't perfect, it's still for all practical purposes a whole lot better than DNSSEC.

I'm not entirely sure what scenario you're talking about, I can't think of one. If your issue is that you can't get a cert without an A record, well, set an A record. I don't see how that's a problem, except if

Yeah, ok, but then you need to ask if DANE achieves that. And the answer to that is clearly "no". DANE never made it past an experimental browser plugin, and as far as I know that isn't even developed any more. In the time wh

They either have their backup codes or there's probably a manual process the pypi team can get them their account back if they can sufficiently show they are the real developers. If you have any form of automated signature verification

What happens if the developer looses his key? Or if it expires? pypi could show a warning that the key has changed. Which is not an actionable or helpful warning. And then everyone gets used to seeing these warnings every now and then. And

Legitimate question, but the answer is simple: No. The cost of CO2 capture largely depends on the concentration of CO2. Transport is relatively cheap. If you capture from the atmosphere, that's the most expensive thing you could possib
