The assumption appears to be "one" Mars habitat, with a lot of engineered systems to support human (and other) life. Three would be better, and each should be capable of supporting the population of one of the others (that is, mea

As "way forward" report it covers only half the problem. Identification of the risks including the likelihoods and hazards is pretty good. I like the notion of contrasting opinions included in the report. But the big thing missin

Yes. Yes. Yes. The relatively warm winters that allowed pine beetles to survive (I think it takes 10 days at -20C to kill them; ymmv) lasted a few years. It may still be going on. The pine beetle is one of the supporting arguments for cli

"fueled by climate change" is just plain incorrect. Fueled by dry trees and brush due to drought with fires started by lightning strikes is a little closer to the literal truth. An average temperature rise of 1.5C over the last 50

wxallowed flag is required for some ports that write to pages that are also executable. OpenBSD prohibits this except when code is run from a partition that permits it by means of a mount flag. Otherwise you get a core dump. And all the pa

Ahh, most of the cost is RAM. Then GPU then CPU. Look at a Dell or HP server configurator website to see why. If you "only" need GPU, a craigslist search should find a less expensive 2 or 3yo server to plug your latest GPU into.

After few years, like 5 years to 10 years, you will want to rewrite the data to a new tape. Even LTO tapes will age and go bad after a while. You don't want to be the one who finds out the hard way how long LTO tape actually lasts. A

Nim is very flexible, and too flexible after you think about it. Compare C with excessive use of macros. That's an antipattern in C and presumably a feature of Nim. C++ is just too big and slow to compile. Rust has a reputation of co
