  • Having done a lot of research into this, the state of things sucks right now. The current open-source options have very bad tracking (like, just a very rough estimate) and are much more focused on smart-watch interfaces, which I get because having made a smart watch development board myself, PPG AFEs are a black hole of NDA-riddled bullshit, manufacturer lies and bad documentation, and no support (looking at you Analog Devices). ZSWatch is the most promising open source project using the best openly - available sensor set with the potential to hit 80% heart rate accuracy, but that is still years away.

    Honestly for half-good tracking, your best bet js Gadgetbridge + a proprietary smart device that is entire locally supported.

    For example, the 100€ Amazfit Helio Strap (no screen) has great heart rate tracking and better than average sleep tracking (old strap style or bicep strap) and you can run it once in the official app to update firmware and extract the encryption keys, then from then on run it completely locally on gadgetbridge and uninstall the official app completely.

    Letting perfect be the enemy of good enough sadly leads to almost useless tracking data in the open source wearables world. For now at least. Making wearables is insanely expensive and to get the best sensors you need NDAs and quantities >10k per year which is unobtainable for community open source projects right now, and you need massive amounts of user data to build good algorithms to analyze the data from the sensors.




  • Suunto is now a Chinese company. They got bought out a few years ago.

    Withings (horrible biometrics tracking, like 70% accurate) and Polar ate the only two European companies of consumer wearables AFAIK.

    Sadly, Apple and Amazfit (specifically the helio strap) and a few Garmin models have the best biometrics tracking. Polar is quite mediocre for their watches, though their chest straps are the best in the business.






  • Going into sewage vats and breaking up solidified waste and oil clogs

    Deep sea oil rig repair

    Underwater dam repair

    Driving public transportation (not enough to maintain a system)

    Elder care (there is a worldwide lack of people willing to clean up piss and shit of often angry, sometimes aggressive people and deal with regular loss for bad pay, much less in an ideal profession freedom world, relative to the amount of people needing care)

    Forensic pathology is something that very very few people enjoy also, but is very needed.

    Urine farmer (hunting luring, sprays for animal repellant)

    Coal miner

    Any precious or rare metal or stone miner

    People love intellectual jobs, creative jobs, and some public service jobs. It is much much harder to find people to do body-destroying terrible-condition manual labor jobs. Ideally those are the jobs to be replaces, but of course capitalists want to replace the former category of jobs because those cut into their profits more.


  • Because America runs off of shirking responsibility to blame someone else: using precedents as loopholes to not have to argue a case.

    1 state does it: 25 others follow suit immediately and it gets insta-passed because “there is a precedent”. See: flock cameras, Bibles in schools, book banning, abortion banning, sweeping climate protection rollbacks, etc… Once one does it, the rest of the cowards use it as a shield like children: “B-B-But theeey doooo iiiit!”
