Just another blog is a personal blog at setphaserstostun.org about systems and programming. Since 2014, 7 different Hacker News readers have linked it 7 times, most often “Monitoring ECC memory on Linux with rasdaemon”. The last post was in 2024, but the archive is still widely read.
Too few sampled comments (5) to say how often HN recommends it.?
Why HN links it
HN readers link this blog for hardware and systems detail: ECC memory monitoring with rasdaemon, IBM POWER8 and POWER9 memory ordering and specs, and Linux keyboard tips such as enabling the Compose key.
Summarised by Claude from a sample of 5 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

HN discussionTo add to this: The POWER7 through POWER9 processors from IBM implement an equivalent to this called "SAO", or "Strong Access Ordering Mode". To quote an IBM engineer: > Currently, power has a weaker memory model than x86. Implementing a stronger memory model allows an emulator to more efficiently translate x86 code into power code, resulting in faster code execution. What's interesting is IBM publishes pretty detai…

HN discussionIBM has solid documentation of more of the Power8 details here: http://www.setphaserstostun.org/power8/POWER8_UM_external_22... Going only by specs, it seems that in many other cases each Power8 core has about 2-4x the resources of a Haswell core: 64KB vs 32KB L1D 512KB vs 64KB L2 8MB vs 2.5MB L3 16 vs 10(?) outstanding L1 requests 8 vs 4 instructions issued per cycle 2 vs 1 stores per cycle (or 4 vs 2 loads if no s…

on “Erlang and IBM Power8 in the cloud: super-high single-system parallelism”Jeez, that's quite a list. There are other, simpler ways of doing a lot of that stuff.

If you want Mac-style keystrokes, try Kinto: https://github.com/rbreaves/kinto But there are other ways: https://medium.com/@petrstepanov/a-macos-like-keyboard-remap...
