  • I started doing the One True Database method because I got worried that the high write count on all the little db’s was abusing a raspberry pi’s SD card. Moved them all to a bigger server with NVME and mirroring to a RAID.

    Not all the compose files make obvious how to reconfigure the db host. Homeassistant uses s a sqlite db built into the container, rather than a separate unit, but you can force it to use a remote db through its config file. May or may not be worth hiding db user/pass in a .env And sometimes there’s trouble restarting after power failure, depending on what order the database, pi, and various containers come back up.

    I also feel it’s worthwhile. I feel better being able to check on all the databases. Feel better not writing to the SD card so much. Feel better offloading those megabytes and cpu cycles from the little pi. It’s been fun snooping through database structures. There have been a couple times where I decided to query one of the ccontain databases directly, or cross from one project to another, and it’s easier (for me) to give a different user privileges to the database and query some deep bit of data than to figure out how to extract it from an API or frontend.

    I’m not even running that many services, but why would I want the overhead of 6 separate mysql instances when I could just have one?


  • It seems like it should be possible to build keyboard (and other) peripherals that exist in both virtual and physical worlds. Give them sensors similar to the hand controllers, so the headset can know where they are in space, project into VR so it’s easy to find and use.

    VR handsets are incredibly flexible as spatial controls, but we’ve got all this evolution and a lifetime of learning just amazing finger dexterity. That control is based more on tactile and proprioceptive feedback than visual, so I think it’s been overlooked in the vision-focused VR space.




  • The US spent a lot of money on soft power, essentially bribing countries to go along with their agenda. Much of that money did actually improve people’s lives, whether it was food aid, vaccinations, or AIDS care. Sure, it was to further their own objectives. Sure, it’s mostly because it’s cheaper to buy compliance than to bomb people into compliance. Humanitarian aid with strings attached is still humanitarian aid, though, or the collapse of USAID wouldn’t be such a problem.


  • The very broad funds definitely will - VTI/VTSAX - but at lower weights and under less time pressure than the rigid index funds (VOO/VFIAX). That takes off a lot of the liquidity squeeze and (presumably) reduces their loss.

    But you have to remember that people who use these funds intentionally invest in obvious losers and willingly overpay for hyped stocks because they believe, in the long run, that buying obvious losers is more than balanced by also buying the unexpected winners.

    SpaceX is just the first time an oligarch tried so obviously to rig the passive investor structure to his favor, and I’m glad the S&P people didn’t cave.







  • What I’ve seen indicates SpaceX will become something like 0.1% of S&P and 0.5% of Nasdaq. If a retirement fund is one of those indexes, and they get ‘forced’ to buy at 2x SpaceX’s eventual value, then that’s a loss of 0.05-0.2%. $50-200 on $100,000 principal.

    Most normal people won’t notice that among the usual stock market noise. Over a hundred million account, though, it’s a huge amount of money getting funneled into the thousands accounts able to front-run the index inclusion, which means, in turn, a huge amount of money getting funneled into the dozens of VCs who got into SpaceX pre-IPO.

    It’s like the scam from Office Space where they collect the rounding errors on interest.

    I had a…call? survey? at some point from an entity that probably gave rise to this data. It was basically a push-poll that used question order and positive reinforcement to try to get people to agree that abortion is murder.

    Mostly, it tried to conflate “human” with “a human,” starting out with things like “are cells isolated from humans still human?” “Can cultured cells be called ‘viable?’” “So would you agree that tissue cultured from a human donor is viable, human tissue?”





  • When an alcoholic sets about seeking forgiveness, they’re supposed to go around to the people they’ve wronged and apologize. They’re also supposed to recognize that they make poor alcohol choices and need to give it up.

    Maybe the MAGA people could recognize that they make poor political choices and give up their voting and their activism.

    Like, I try to think how I would react if I made a choice so monumentally bad that thousands of people died, people were tortured, or an entire national economy thrown into disarray. There’s no reparation I could pay to compensate; no sacrifice I could make to balance the scale. That’s kind of the point of forgiveness: the wounded party has not been made whole, maybe can not be made whole, but accepts that trying to wring compensation out of the offender will only make another injured party. But there’s still the question of how to keep the offender from doing it again.
