• Connection Machine Lisp was discussed via two Hacker News threads (https://news.ycombinator.com/item?id=24893924 and https://news.ycombinator.com/item?id=12281637) as an influential parallel-processing language for AI and symbolic computing.

• Participants explored adapting the ultra-simple “bubble CPAP” design—normally used for neonates—into an open-source, low-cost PAP or bilevel device for treating sleep-disordered breathing such as apnea and UARS (Upper-Airway Resistance Syndrome).

• UARS was highlighted as a widely under-diagnosed condition that can masquerade as ADHD or treatment-resistant depression; proper sleep studies must score RERAs (respiratory effort–related arousals) to detect it.

• A jailbreak project for ResMed AirSense CPAP machines was mentioned, allowing firmware from higher-end bilevel/ASV models to be flashed onto cheaper hardware, dramatically lowering therapy cost.

• Vitamin D (cholecalciferol) supplementation was cited as a low-effort intervention to reduce COVID-19 pneumonia risk, referencing a 2020 paper in Medical Hypotheses (https://www.sciencedirect.com/science/article/pii/S0960076020302764).

• Self-experimentation plans for cognitive recovery included a stack of creatine (brain energy metabolism), exogenous ketones (ADHD), a neurotrophic agent (gray-matter repair), psilocybin (behavioral flexibility), and an empathogen (self-acceptance), with emphasis on treating underlying sleep pathology first.

• LibGen now provides IPFS gateway links for every book entry, and the LibGen Desktop client (https://wiki.mhut.org/software:libgen_desktop) was shared as a convenient search tool.

• Glasgow (https://github.com/GlasgowEmbedded/glasgow) was introduced as an open-source “Swiss Army knife” for electronics debugging, and its lead developer also created SolveSpace parametric CAD (https://github.com/solvespace/solvespace).

• A brief debate on web hosting practices noted that Cloudflare’s anti-bot JavaScript challenges block non-mainstream browsers, prompting a switch from DigitalOcean’s static-site service back to a self-managed Azure VPS to avoid Cloudflare dependence.
