- A 16 MHz AVR Arduino (32 KB Flash, 2 KB RAM) can perform real-time shaded 3-D graphics at ~8 million 8-bit multiplies per second—roughly 386/16-class performance—demonstrated by the open-source “arduboy-teapot” engine (https://www.a1k0n.net/2017/02/01/arduboy-teapot.html).  
- Flash endurance (10 k erase/write cycles) allows an average 2 bytes/second of self-logging over 5 years, making the Flash a viable adjunct to SRAM for data-heavy embedded projects.  
- Discussion of stimulant pharmacology: Vyvanse patents expire February 2023; participants debated whether extended-release formulations reduce abuse liability or merely prolong sleep disruption and dependence.  
- Gwern’s nicotine self-experiments (https://www.gwern.net/Nicotine#conclusion) were cited as evidence that slow-onset stimulants can yield cognitive benefits without euphoria, though skepticism was voiced about subjective vs. literature-based assessments.  
- A participant reported developing nicotine gum addiction during COVID, later switching to Vyvanse and then quitting nicotine entirely, illustrating real-world trade-offs between different stimulant strategies.  
- Concept floated: design a “Schmitt-trigger” style drug-metabolism control system that sharply cuts off exposure beyond a threshold to prevent compulsive re-dosing.  
- Forbes article shared on ovarian aging: startup Rejuvenate Bio is pursuing gene-therapy approaches to extend female reproductive lifespan (https://www.forbes.com/sites/alexzhavoronkov/2022/05/19/can-we-fix-ovarian-aging-here-is-one-startup-up-for-the-task).  
- New Science report on NIH funding practices described a “Benevolent Ponzi Scheme” where labs complete 80–90 % of a project before applying for an NIH grant, then use the award to finish and start the next cycle (https://newscience.org/nih/).  
- Inquiry about smartphone-attachable GC/MS “lab-on-a-chip” devices concluded that such miniaturized spectrometers are “not even close” to commercial reality.  
- Bionic Reading Chrome extension for rapid fixation-guided reading was shared (https://github.com/ansh/bionic-reading).
