   I asked before, but didn't get an answer. Darcs is criticized for lack of soundness and potential exponential merge complexity -- which I'm not sure I've actually run into -- but that's Darcs2. I haven't actually

   If you haven't read Landin's "The Next 700 Programming Languages", you should. I don't know if it's still outside the ACM paywall, but you'll find it in a web search if not. It introduced the offside rule

   As a quick test, 1337x.to is near the top in mojeek, exalead, infinitysearch, ecloud spot (searx).

   Thanks. That sounds vaguely familiar now.

   For what it's worth, Fortran goes further with (optional) "end function X".

   Can't semicolons essentially be either infix or postfix (terminators), depending on the language? Parsing the offside rule -- I know that's not actually Python -- can be done straightforwardly with a parsing combinator transformer

   Mathematica is surely not a Lisp, as exemplified by the above. You may be able to find old commentary from Richard Fateman about that, e.g. from comp.lang.lisp, and from Kent Pitman on Wolfram's attitude to the language.

   For historical interest, I have wondered if this also applies to TCP/IP over X.25, which was used for a while on JANET, the UK academic network, when IP became irresistable. I remember that as working well, but perhaps it didn't

   There's also an advantage of UDP being able to resume after losing the link, as with mosh and a feature of wireguard (and other VPNs?).

    Is that meant to imply that the privacy protection and un-bubbling of the "middle men" is bogus? (I don't know about Qwant, but DDG isn't solely Bing, and it feeds some worthwhile organizations with donations.)

    I'm surprised there doesn't seem to be anything in CRAN using SuiteSparse. It could presumably run at petascale, similarly to the dense support, if someone did similar work.

    I doubtless mis-remembered about MKL, thanks. I'm baffled why there would be a problem with commercial users running a free software program like Julia or GNU Octave+SuiteSparse; that's Freedom 0. (And commercial /= propriet

    Yes, though I don't know what version. Maybe I should have said new system, but it's a new micro-architecture, as I understand it, with an unsupported ABI.

    Yes, if it's available for the OS you run, like EL or Debian. It's aarch64.

    The SIMD makes little difference to the bulk of the system, but you want dynamic dispatch where it does, at least on a typical HPC system, which isn't heterogeneous five years down the line, and in things like libc generally.

    The thing that makes a significant difference is BLAS, and it's easy to substitute. There are some old numbers at https://loveshack.fedorapeople.org/blas-subversion.html#_add... Most of it is unlikely to benefit much

    Only roughly additive. Some obsolete features have been dropped, though that doesn't mean compilers have dropped them.

    If you care about small matrices on x86_64, you should look at libxsmm, which is the reason MKL now does well in that regime. (Those numbers aren't representative of large BLAS.)

    You just run MKL from the oneapi distribution, and it gives decent performance on EPYC2, but basically only for double precision, and I don't remember if that includes complex. ACML was never competitive in my comparisons with Goto&#x2

    I've made the point that GCC and free linear algebra is infinitely faster on platforms of interest (geometric mean of x86_64, aarch64, ppc64le) while still having similar performance on x86_64. I thought MKL used suitesparse, or is tha

    Apple is obviously a contrast with the usual state of affairs where one of the first signs of a new CPU is in the GNU toolchain.

    I don't need to; the first I remember hearing of Trump was locals sounding off in an Aberdeen pub. Anyway, "local golf club owner" is my idea of parochial, and a good joke.

    I can't remember for sure whether Toolpack's revision control component actually operated with ASTs, but I think it did. Certainly there was a semantic diff and patch. (Toolpack was quite an advanced a Fortran77 engineering tool

    Yes, except that I don't think that's niche. With darcs, I have a collection of patches available from developments/contributions, and a release is a set I'm happy with on top of the previous release tag. If one of the
