For "corporate" accounts, isn't PIV better, since it works with more than web (like Kerberos without contortions) and lives on your id card fairly readily?

But I thought Carmelites were always friars (the White Friars), who get out and do things like found my old school -- not monks, like Benedictines. Of course there was rather more than self-sustainment in medieval England, at least...

The necessarily poor performance of micro-kernel-ish systems was a myth even for a 1970s design (not to diminish Liedkte's work). In the '80s I used fast (realtime, multi-access) GEC OS4000 systems, thankful not to need VMS often

Is it clear people wanted to get away from Lisp rather than use a more-or-less clone of S? (One of R's originators did propose moving back to a Lisp base [1], though part of the justification was HPC, which is now at least partially c

Something not mentioned is Plan 9 security. Specifically Unix file handles are often quoted as like capabilities, but you do need namespaces to make that useful for isolation. I don't remember exactly what the paper on security in Pl

by gnufx 4y ago
In contrast to what Drew says, Plan 9 probably failed because it was proprietary, not because of the Unix predecessor. If it had a free licence at the time, I doubt RMS would have felt the need for GNU, though I don't know what he&#x2

Since BLAS (and LAPACK) have an essentially well-defined ABI, anything dynamically ELF-linked doesn't need specific support. You can just LD_PRELOAD, say, OpenBLAS or blis+libflame (as in AOCL) to use them. You can also make a trivia

That's simply implausible for any proper measurement of the large-dimension level-3 operations that normally matter (and probably others I haven't measured). OpenBLAS certainly uses AVX2 assembler on Zen if it's built and ru

Yes, there's a bunch of common implementations which use it, like (Debian packages) eatmydata, fakeroot, datefudge, substitute mallocs. (One implementation of) fakeroot spawns a demon. Oh, and if you have something statically linked,

Concerning ldd, see the security warning in ldd(1). I'm not sure if it's still an issue in current GNU binutils, but lddtree is supposed to be safe and the tree may be more useful.

Outside C++, for instance, constructor functions are useful in LD_PRELOAD objects to fix up things before a binary's entry point runs.

From the other side of it, there's "How to Write Shared Libraries": https://akkadia.org/drepper/dsohowto.pdf Edit: LD_PRELOAD would have been useful to mention in the article. It's a useful mechan

That doesn't say exactly what was run and how. From measurements with nvblas, that difference could be dwarfed by the effect of tile size and pinning buffers or not.

There's commentary here which seems to be talking about matrix multiplication in general and ignoring real implementations, which are dominated by considerations of the memory hierarchy. They actually introduce operations, like packin

It seemed to be in a similar space to Genode when I had a brief look. Is it clear how it compares? A system that claims to allow you to configure it in microkernel and other modes might be interesting for comparison of the approaches, but

http://www.microkernel.info/ probably should list some others mentioned here. I've only glanced at it, but there's some teaching material from L4 land apparently in the usual excellent German technical English at

Hear, hear. Many, possibly most, security failures I see reported seem to be at least related to ambient authority-type sins at one level or another. If only that was widely recognized after all this time.

Note that criticism of the BBC Domesday Project as short-sighted for using LaserDisc is mis-placed. It's worth reading https://catless.ncl.ac.uk/Risks/25.44.html#subj7 (Some of Prof. Newby's career subsequen

As the article implies, Dijkstra was specifically wrong about FORTRAN, as defined at the time — the '77 standard, when it was still only conscionable to SHOUT 6 alphamerics. “… you probably know that arrogance in computer science is me

What's the problem with FUSE? Anyway, it needs a daemon on the remote system, but perhaps https://github.com/u-root/cpu is suitable. (I can't vouch for it, not having used it.) The HTCondor batch system also
