   I know your comment is satirical, but unfortunately I know quite a few people, in wealthy countries, for whom an 11 by 11 square cell of their own would be a welcome upgrade to their current, smaller, precariously rented space.

   In England here. I wouldn't say the buses work pretty well - journeying on them tends to make me sick fairly consistently, unlike trains which do not. I think it is due to the bumpy roads, terrible suspension and polluted air. The dif

   Ooh, that observation that the antigens are not known sounds like a really promising field for analysis and discovery tools. Reverse engineering the antigens from the cells that have evolved to recognise them.

   This whole subthread about asynchronous objects, and the actor model, made me think of "background" processing where objects have a running life of their own, and it reminded me of a recent HN comment about almost the opposite app

   For work I had to connect a portable audio player to a USB audio amp recently. The amp is designed to plug into a regular computer, using standard USB-A at the computer end. Since the audio player had USB-C we needed a basic USB-C to USB-A

    I think the nursery construct described in that link looks a lot like par blocks in Occam, Handel-C and XMOS XC.

    In my view, the idea that optical PoW will reduce the energy cost of PoW mining is only temporary, because the Capex aspect of photonic miners is likely to be only a temporary competitive advantage - just like the Capex advantage of buildin

    Alt+Key doesn't save any keystrokes over Esc+Key anyway, and I think the Esc version is easier to type. Especially things like Esc : (which is Esc then Shift-;) is surely easier to type than Alt-Shift-;.

    On some systems setjmp/longjmp also change the signal mask, and are just as slow. For those there is _setjmp/_longjmp. The Linux man page explains excellently: "POSIX does not specify whether setjmp() will save the signal mas

    You can implement something similar without needing any special kernel features: - Userspaces cooperative scheduling for all the tasks, in multiple threads if multi-core. - A periodic timer signal sent to all the userspace threads. (Or one

    If the modification date is changed, then its idempotency is open to application-specific definition.[1] One way you might call modification time changes idempotent is if you don't care about modification times. Another way is much sub

    "Safe" and "idempotent" have defined meanings in the HTTP standards, that's why I used those terms, and provided the RFC section that explains for anyone who cares to read more.

    I must disagree. I've done a small number of 48 hour stints in circumstances where the need arose, and I've never in my life touched amphetamines or anything else like them.

    I wouldn't be comfortable with one backup device kept in secure storage somewhere. If it fails you won't know, and you'll be operating without redundancy without knowing. So that means keeping two or more devices in regular

    Judging from the twitter thread, idempotency vs. safety is not widely understood. The "create a key-value pair" operation described here actually is idempotent. The requirement on GET is that it must be safe , meaning no side-e

    Equality of opportunity to become rich and/or acquire lots of control is certainly not an inherently socialist concept. Arguably, it's not even allowed in true socialism.

    FIDO2 is working, but I wouldn't call it "golden" at all. Tying authentication to a single device you can lose, especially one controlled by the device vendor not by yourself, sounds highly risk prone to me. As far as I'

    If I understood correctly, the extra round trip on the reader only occurs with left-over intents, which are the product of an earlier failure. So: - Writes are faster due to fewer round trips in normal running. - Reads are the same speed in
