ivan / check-brotli-cve.sh
Created October 22, 2026 02:12
LLM-authored slop script to scan NixOS for bundled brotli
#!/usr/bin/env bash
# Model-output: Claude Opus 5.5
#
# Read-only triage for CVE-2026-111497 (brotli decoder out-of-bounds write, fixed upstream in
# google/brotli@0ed4268a): which running or installed binaries carry an unfixed decoder, and
# whether anything crashed the way a failed exploit attempt would.
#
# Usage: ssh root@HOST bash -s -- [--closure] [SINCE] < check-brotli-cve.sh
# --closure also scan the /run/current-system closure (about 1 minute per 2000 store paths)
# SINCE start of the crash search; default 2026-02-27, when the upstream fix went public

Fix the walking speed in The Witness witness64_d3d11.exe (GOG, Patch 21.12.2017 from 06 March 2018) to not have sqrt(2) walking speed on stairs
#!/usr/bin/env python3
# Model-output: ChatGPT 5.6 Sol (High)
"""Patch The Witness stair movement and bypass its startup corruption guard.
The movement patch rescales a player-only walk-manifold request when traversal adds
vertical displacement. The startup patch removes the conditional jump that routes
a zero critical-asset sentinel to ``fatal_error_data_corruption``. The PE file size
and section count remain unchanged.

ivan / rsync tips.txt
Created May 31, 2026 07:20
rsync tips
rsync -av -@-1 as the baseline thing
or with --delete to remove things from DEST, and probably
--delete-excluded when using --exclude
rsync -@-1 compares timestamps by nanoseconds instead of seconds, which is important for transferring e.g. PostgreSQL data; rsync doesn't read the data inside each file if the (mtime, size) matches on both ends, unless you:
rsync -c
rsync -X to also copy xattrs (slower)
rsync -H for hard link preservation (uses memory to track all the inodes)
rsync -S to preserve sparseness in sparse file
rsync --zc=zstd
rsync --zc=zstd --compress-level=6 or maybe 8 where the link is slow and extra compression is useful
