I wrote a generic kernel driver overlay for error correction for block devices on Linux (Winter 2017-18) for a student org at my university. Interned at NVIDIA on their Linux graphics driver in Summer 2019
IMO QEMU is a nice spot between important, straightforward to contribute and relatively understaffed compared to how widely it is used. I have found multiple behavior/stability issues that I’ve fixed on my own (exposed though OSdev-adjacent work) and submitted to the mailing list
I've been running a SIGECOM chapter at UIUC and the main theme over the past four/five months is people meme-ing about Beanstalk and how its such a shit show. My original concern had to do with the stability lever only working to decrease the value, so it inherently requires a "distinct triangular shape" to keep itself running. I didn't take it seriously enough to do a deeper analysis (mostly because I'd find something like this, but I can't really do anything with it legally) but there's about $10k invested in the ecosystem as LPs/bond-owners within my group of friends.
I did 72hr fasts and averaged about a pound lost per day at the fastest (i mostly ate eggs and cream cheese when i did eat anything). I exercised pretty heavily too but entirely cardio (physically weaker obviously so don’t want to fail lifts). I went from 255lbs to 200lbs over the course of two months (currently sitting at 180 but that’s because I’ve released it quite a bit)
