   "Practicality beats purity", and conversions like integer<>floating point are ripe for efficient implementation using a small number of gates. CVT.W.D in MIPS did that decades ago (including setting a condition bit for case

   How do you verify that everything is behind a feature flag? How do you verify that everything will work right once multiple feature flags are enabled? How much of a negative effect do feature flags have for reasoning about the software?

   I hope that ultimately we are able to hear the full story, and that it's something more interesting than embarrassing.

   My intuition tells me that no Turing machine that terminates for all unbounded inputs can run "much longer than" a busy-beaver turing machine. However, the numbers that describe how long BBs can run are .. quite large. The numbe

   honestly it's not as bad as I was worried it would be, given the awful wasteland that is crowdfunding. If they work, features like the entrance and the one-way access to the comb seem like they are good if you have are afraid of bees a

    This is a great strength of the Debian installer—which is not to say it's unique, it's just the installer I'm familiar with. You can do essentially anything you need to do in a (nearly-)hands-free installer, which is great w

    That's the one where I wanted most to quibble with the "explanation" of why there is no set answer: To me, the top of the line answer is that the value of the string constant ' ' as an integer is implementation-defi

    Wow, what is going on with gnu parallel? It also takes 5-7x as long as "xargs -n1 -P#" (debian stretch, i7 CPU 4C/8T). Of course, one GENERALLY runs programs like xargs or parallel where there's nontrivial work to be d

    I also tried to verify "table 6", which appears to be correct except for the second row, where the hex value shown for "C" is accidentally the same as "E". Correcting it to 0x7761792c20666f72 causes all the &q
