Oy vey, veering off topic, but whatever... BAM is a sequence of zlib-compressed blocks. Each of them has a checksum, and any corruption gets past it with probability 2^-32. Any sane software will give you an error. When in doubt, just de

It really can't be bit flipping on disk. First off, the checksum would catch it. Second, the file is compressed, so flipping a bit turns it into complete garbage. Third, BAM uses a length-prefixed coding in several places. A flippe

Err, no. The CIGAR is not a checksum, even though you'll notice if it's corrupted, because it won't match the read length anymore. However, BAM is zlib-compressed (even if you asked samtools not to compress it). Each block

Fluoride (with a 'd') is not fluorine (with a 'n'). The difference is as big as that between sodium and sodium chloride. You can eat one, but not the other. The most powerful oxidizer in MSR fuel salt is the U(IV) ion.

You mean ceramics? There are so many to chose from, and most are unusable for one reason or another. The leading candidate being investigated is carborundum (silicon carbide). It doesn't corrode in molten salt, it low appetite for ne

...unless the sacrificial material is a component of the salt anyway, like Beryllium. ORNL proposed to have a Beryllium rod in contact with the fuel salt. It isn't needed to prevent corrosion of Hastelloy N in clean fuel salt, but it

The corrosion problem has been blown way out of corrosion, and I suspect, you're confusing it with the graphite swelling problem. Pure nickel won't corrode in fuel salt, so to a first approximation, Hastelloy N works fine and last

I'd have said Jadetex. I fondly remember the SGML toolchain; the XML stuff felt horrible in comparison.

However, that's an eight hour shift, not twelve as mentioned in the article. Eight hours of work, eight hours of sleep, and two hours of commuting and personal hygiene still leaves a full six hours per day to use however she likes.

Just a way of storing hydrogen, as if that was a solved problem. Hydrogen liquefaction is less than 50% energy efficient. Haber-Bosch compares favorably to that.

Not necessarily. Ammonia burns to water and nitrogen, primarily. But the process is complicated, goes through many intermediate compounds and radicals, and won't have time to complete in a piston engine. The exhaust will therefore c

Seriously, another one? https://xkcd.com/927/ Why was CBOR not good enough this time? Still not enough string types? Oh, indeed, CBOR doesn't have markup, whatever that means.
