Table-driven parsers with custom per-statement tokenizers are still common in surviving Fortran compilers, with the exception of flang-new in LLVM. I used a custom parser combinator library there, inspired by a prototype in Haskell's

It goes back to the CDC 6600 at least, and is most often seen as part of Hamming distance computation (pop(xor(x,y))). But it turns out to be really useful for other things (trailing zero count), and worth having in hardware since the soft

Universally distinct would seem more correct than unique , at least mathematically speaking, unless there's only ever going to be just one of them.

It was invented so that IBM could sell more gear to the institutions that employed them.

Fortran compilers were historically implemented by hardware vendors in order to sell their hardware, and this still largely holds true across the surviving implementations with the exceptions of GNU Fortran (obviously) and nagfor (commercia

I really don't understand the disdain for Fortran on HN. While it's not the most well-defined or portable programming language in the world, it does its job pretty well for those who need it, and has more actively maintained impl

That’s what was done on the CDC 6600 with two handy values, B0 (0) and B1 (1).

What "certain versions" of Fortran since Fortran II did not have the ENTRY statement?

Fortran used to have DO loops. It still does, but it used to, too. Algol's the one with FOR loops.

You really think that Perl has billions of lines in active use in critical applications and libraries?

LLMs are so very good at emitting plausible, authoritative-sounding, and clearly stated summaries of their training data. And if you ask them even fundamental questions about a subject of which you yourself have knowledge, they are too oft

Do these tools support Nikon's "high-efficiency" compressed NEF files? I suspect that they're encumbered by patents.

Even a short summary of the Wake can suffice to get you started. You're never going to understand it all, and that's okay, but even a brief chat with a Wake fan can give you the basic clues of its structure and the HCE/ALP S

I don't think that English changed as much, but I could be wrong. Shakespeare's not hard for a modern English reader, given a decent edition with vocabulary hints in the footnotes. I got through most of it as a sophomore.

I think that English might have fewer opportunities for this sort of thing; I found Beowulf to be surprisingly dull in the original. Greek, on the other hand, has lifetimes' worth of good stuff in its ancient forms, and can really rewa

Your previous readings of Finnegans Wake are your preparation for your next one.

If you think spell(1) is AI, you misunderstand at least one of them.

Pedantically, will this be one mean solar light-day, or one sidereal light-day?

It's a valuable but scary experiment to query an LLM on basic subject matter in a field that you know a lot about. Ask those basic questions first.

LLMs, kind of like Bill Bryson's books, are great at presenting "information" that seems completely plausible, authoritative, and convincing to the reader. But when you actually do know the truth about a subject, you realize

Fortran is recursive by default.

Why?

FORTRAN '77 conforming code is (almost) always Fortran '90 conforming code too.

And so have the various editions of standard Fortran. In fact, ISO Fortran’s abstract floating-point model is so old now that it’s confusing, since it’s basically IEEE-754 but off by one in its exponents.

You don’t have to worry about the order of evaluation. It doesn’t seem like a big deal, until you have a big messy problem with data-dependent interdependency. Also, every list is a generator, and every indexable container is an instance

I wish so badly that there were a statically typed, pure, and lazy Scheme.

That's a reasonable assumption, but it turns out to rarely be the case with WG5/SC22/J3. There are exceptions (like SIND, SINPI, &c.), but most new features in Fortran standards are committee inventions without prototype
