Tested Hermes Agent x_search on a basic X Premium plan (M4 Mac mini). Docs require Premium+ but the basic tier worked. Covers uvx + OAuth setup, the 8.4s vs 58.4s timing gap, and prompts that never invoke X search.
Tested Mageia 9 on a junk Dell Latitude 5310: SATA RAID hides the NVMe, BIOSConnect fakes USB boot failure, ifcfg-rh keeps Wi-Fi unmanaged until keyfile migration.
Tested Q_rsqrt on Apple M4 (Mac mini) and Zen 3 (Ryzen 5800HS / WSL2). M4's -O2 already rewrites 1/sqrtf to frsqrte and ties Q_rsqrt; x86 clang needs -ffast-math or hits a 12x gap. Hand-written NEON/SSE wrappers turn out slower. Newton 0/1/2 error and the Lomont constant covered too.
Tested on M1 Max: Floyd-Steinberg halftone + BLE pacing + a vendor-specific density command `1D 49 F0 nn` to print sharp photos on the Sugar YMP-01 thermal mini printer from Python.
Tested on M1 Max: switching a Python BLE client to RFCOMM (SPP Ch.2) cuts transfer from ~60s to 5.38s for a 140KB JPEG. Covers PyObjC quirks, macOS Bluetooth entitlement, and an isolation experiment confirming olie.xdev's 'possibly not required' steps.
Tested BMBrick's LEGO mosaic pipeline in Node + sharp with a 45-color palette: RGB nearest sprinkles 16% glitter and silver on photos, OKLab + material penalty wipes them out, and the original 0.15 is 7× overkill (0.02 is already enough).
Tested Orbis in Docker: psf/requests (35 modules) makes a clean 3D graph, expressjs/express (98 modules) collapses into one giant sphere. Notes on what tree-sitter actually captures for code-review prep.
Tested Klein 9B + 9B NSFW LoRA on M1 Max 64GB via mflux 0.17.5: 1m51s/512, 5m37s/1024 q4, 224/224 LoRA keys match, NSFW prompts uncensored, Japanese subjects work with helper tokens.
Tested Gemma 4 MTP drafter on M1 Max 64GB with mlx-vlm 0.5.0. Only the 26B A4B MoE got +13%; 31B Dense and E4B got slower. Code gen vs short haiku prompts flip the result.
Klein 4B / 9B / Base LoRAs aren't cross-compatible — a 9B NSFW LoRA throws 'lora key not loaded' on mflux's 4B path. The variant map, what mflux runs today, and where the working hands-on test lives.
