Haskell has an alternative parens-and-braces syntax to the offside rule; that was meant particularly for machine-generated code if I remember correctly. Edit: I meant to add: you need to decide whether ";" is terminates or joins s

I don't know what Dwarf Fortress is, but that's what I meant. Fortran now has INTENT specifiers, and you can expect constants to live in .rodata(?) on ELF systems, so you get a SEGV if you evade any compiler warning.

I was responding to "completely absent in all modern languages". Alternate return has been in the standard since '77, and Fortran 2018 seems modern enough.
424.

Yes, as always, it depends. The typical problem with array operations, e.g. in Fortran, is how well they're "scalarized", and the possible cost of not doing copy elimination over subroutine calls, for instance. Presumably th

Not hate for loops, but if you replace them with, say, array operations, you've removed the need to prove your loops correct -- or removed a possible source of error from getting them wrong. I guess what's clearer is a matter of

Fortran actually passes by value-return, or whatever you call it, not by reference. The call may still be compiled by reference, of course, and it used to be fun to change the value of a number in the days when it wasn't in read-only

Is the PL/I alternate return fundamentally different from Fortran's (or FORTRAN's in those days)?

Although it's one of the "different" things, along with memory model, the page size is the same for Fedora aarch64 if I remember the discussion right. Is POWER9 compilation generally poor compared with other targets? It didn

If the implication is that POWER is somehow new, I first used it when it was RS/6000 and introduced FMA. There was subsequently a rather large installation at my lab. Firefox without the JIT is only a problem with the "modern&qu

Er, no. I do that stuff (well, I'm not clever enough for C++ generally, and it would be OpenMP rather than plain pthreads) on the sort of nodes that Sierra uses. However they mostly use the GPUs, for which POWER9 has particular suppo

You will generally want at least -funsafe-math-optimizations for performance-critical loops. Otherwise you won't get vectorization at all with ARM Neon, for instance. You also won't get some simple loops vectorized (like product

GCC attributes give you per-function control over both target and optimization options (unfortunately not with Fortran). I'd have to look up what's available, but some per-loop control is possible with OpenMP pragmas too (perhaps

If you're allowed an accelerator, perhaps something like https://en.wikipedia.org/wiki/ISIS_neutron_source if not in a confined space.

I haven't checked quite what Keyoxide is doing, but I'm not sure cryptography is the only thing worth auditing for security.

I probably wouldn't just rely on SSH host key pairs either outside something like a compute cluster.

Not the main point -- and I don't know why a filesystem needs to be in kernel space -- but the swipe at network filesystems is wrong. Of the ones I know, at least OrangeFS can use public keys, if that's what you want (though I do

If you rely purely on Tailscale networking, and trust any process on the client, why do you need PAM (assuming OpenSSH sshd configuration if you can't simply listen on that address)?
448.
by gnufx 5y ago
No, within the last month. One thing is that I don't see anything about auditing for Keyoxide, but Keys is up-front with a warning.

There's also https://keys.pub/ (from someone ex-Keybase, if I remember correctly). I haven't looked at either closely. Can anyone compare and contrast?

Concerning Firefox-type forks, https://cliqz.com/ (RIP) seems relevant. At least Brave has taken on the search engine.
