Too few sampled comments (4) to say how often HN recommends it.?
Why HN links it
HN readers cite this blog's security research write-ups on game console and GPU hardware, including a PS Vita HENkaku exploit teardown and Nvidia TSEC and Falcon firmware key extraction.
Summarised by Claude from a sample of 4 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Simple blog where I document and share my hacking related adventures.

HN discussionThere was a lot of work done by the Switch hacking community, which uncovered some fatal cryptosystem flaws w.r.t. secretful FALCONs. It is apparently possible to leak the hash against which the secretful falcon compares against in the hardware from the High Security side of things to LS. It's a fairly in-depth and tricky thing though. Basically you're having to do firmware reverse engineering and basically chaining…

The benchmarks are atrocious: https://www.phoronix.com/review/nvidia-nouveau-2019 To expand on this, nouveau is cryptographically handicapped by nvidias decision to lock reclocking and power management API's behind cryptographic firmware signing required to execute in FALCON High-S…
