Indeed. He's said that Sutherland invented OOP (along with the other things Sutherland "didn't know was difficult"). Like most people, I guess, I found out about Sketchpad from Kay.

Concerning the mention of closures: … it does seem to me that … OOP represents the discovery by the mainstream community that it is a good idea to associate code with data, but, since they still don't know how to do closures, they have

Is "kpatch" there actually the same thing as RHEL's kpatch? I thought Kernelcare used something proprietary.

Actually, POWER9 RHEL7 has Linux 4.x, where x depends on the minor release -- unfortunately not the latest on the system I use. I think aarch64 is similar, but I'd have to look for rpm to check. They need similar attention, of course

For what it's worth, some Fedora maintainers maintain that maintainers generally should use branches and not spec conditionals. Other maintainers ignore them. That's a branch for every Fedora and EL release (assuming you maintai

It's normally worth reviewing original work in a field for understanding and lessons. Some current work inspired by the 6600 from all those decades ago is https://www.crowdsupply.com/libre-risc-v/m-class/updat

Note the serious use of ZFS. Also faith in Lustre, which has been known to be slagged off for its design and operational problems.

GNU software is more likely to be "free" than "libre", like FreeIPMI in this context. (As far as I remember, that was originally part of Gluster, the GNU cluster system with existed for a while before the filesystem too

A KVM system is not a BMC. Running a cluster (even a fairly small one) you probably want power control, e.g. with powerman, serial console availability, e.g. with conman, metrics, e.g. via freeipmi and some monitoring solution, and probabl

I don't know why FORTH would come into it. OpenBMC does a different job to Open Firmware (Sun Openboot v. ILOM). OpenPOWER boots through Linux -- or at least some of it does. What I really need from a BMC is properly-working and secu

I don't suppose it's being modified, but I wonder how much -11 code is still running, even on real hardware.

Machines that matter to who? Maintainers of packages for OSes that support s390x (RHEL/Fedora, SUSE, Debian), Arduino AVR users, AIX users, embedded systems people with, say, Coldfire or some DSP? I don't know to what extent por

I don't know exactly what Pin does, but probably dyninst, which also supports Arm8 and POWER. It won't avoid slowdown, though.

Bad luck! Emacs Ediff worked well for me before Git, and it still does (frequently in a tty, and preferably not with Git).

I wonder how many implementations there were of that sort of thing. I wrote one for an HP flatbed plotter sometime in the 80s to digitize plots from papers, but I never heard of another. I don't remember the implementation, but it mu

Back in the days of X.25 and the UK "coloured book" protocols, grey book email went over blue book "network independent FTP" (in batch). I don't know how NIFTP compared with ARPANET FTP as a protocol, though.

Not yet implemented, but Solo 2 has a "stretch goal" to provide HSM functionality, if that would be good enough. https://www.indiegogo.com/projects/solo-v2-safety-net-agains...

Not Fortran, in which you originally needed to SHOUT, though you couldn't go SHOUTING? It was good enough to implement one of the earliest RDBs, after all, which sounds business-like.

Yes, in general, hwloc (from which lstopo comes) is the thing to use for anything to do with CPU/memory topology, e.g. pinning to logical cores rather than physical ones whose numbering can even change with BIOS updates.

The reference BLAS in Fortran is indeed slow. I'm not aware of any tuned version in Fortran. It might be possible to re-write the BLIS structure in Fortran and get reasonable performance on, say, Haswell, but not on SKX, if we talk x

Indeed, basically, though you may lose from lack of direct access to the hardware. But it's typically expensive. Do AWS and GCP actually have RDMA fabrics now? The AWS "low latency" one of a year or so ago had a similar late
