casualhacking is a personal blog at casualhacking.io about hardware and security. Since 2019, 3 different Hacker News readers have linked it 3 times, most often “Debug UEFI code by single-stepping your Coffee Lake-S hardware CPU”. The last post was in 2020, but the archive is still widely read.
Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
Linked in a thread on llvm-libc, the C library project. The posts cover Linux C library compatibility, such as glibc symbol versioning and binaries failing to run on older or newer systems.
Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
A personal and public journal of technology exploration, usually about computer security and hardware.

What Hacker News says?
> Binaries compiled against today's glibc can fail to run on a machine that hasn't been updated since last week because they rely on a new / different symbol. Note, however, that it is a Glibc bug (modulo Drepper’s temper) if the reverse happens: Glibc symbol versioning ensures that binaries depending on an old Glibc (only) will run on a new one. So the proper way to build a maximally-compatible Linux executable wou…
