- WikiHouse open-source construction project (wikihouse.cc/guide) was shared as a resource for rapid, low-cost building using CNC-cut plywood joints and open hardware designs.  
- Discussion of a DIY academic journal format proposed three core sections: (1) academic findings with full derivations, (2) detailed “how you built your equipment” instructions including exact pricing, and (3) an explicit “questions to answer” section to guide future research.  
- A member sought an AI/ML expert to help reverse-engineer Mountain Dew promotional codes, describing a feedback-driven generation scheme where valid codes are used to train a model that outputs new candidate codes.  
- The concept of using a fuzzer—software that systematically generates and tests large numbers of potentially valid inputs—was introduced as a possible approach for the promo-code problem.  
- Practical hardware tip: mixing graphite powder with oil was suggested as a quick fix for noisy computer fans exhibiting grinding sounds.
