  • I was just thinking about this. Love these videos. Cooling of a solar panel is a good application, as long as it gets cold enough for long enough to re-solidify at night.

    An alcohol/NaCl solution with a stabilizer can make an ice pack that freezes colder than water. That could be used to keep ice cream frozen in an ice chest.

    It would be cool to have recipes for a few different temperatures. There’s a German company Qool Products that sells PCM temperature elements (ice packs), at a variety of temperatures, to store ice cream up to red wine/cellar temp in their ice chest. With some trial and error I guess we could now make our own!






  • Piwigo is more like a shared gallery. Users create album/folders and upload individual photos, which other users can access. Piwigo has poor support for videos and no support for Live Photos.

    Photoprism has only a single user for the free tier. It supports Live Photos and videos, and individual photo uploads. It does facial recognition tagging.

    Immich supports video/Live Photos, facial recognition, and has multiple users, but it expects a full backup/synchronization (not individual photos). Sharing between users is manual, not automatic or permissions-based like Piwigo. Each user has access only to their own backups or shared albums.

    In summary, I think Piwigo is the simplest to set up and use, but it doesn’t do much beyond photos - it’s a simple shared gallery. Photoprism is good and stable, but you have to pay a subscription for multiple user accounts. Immich is rapidly developing, which means things will break, but also it has the most features. My only issue with Immich is that I don’t want to use it as a backup - only as a “best of” shared gallery. While it’s possible with Immich, I would have to maintain an Immich album on my phone, and sync only that, and I would have to set up shares with other users manually.







  • Radar and Lidar also get a lot of noise from heavy rain or snow. Fog can be just as bad. Some conditions just aren’t safe to drive in, regardless of who’s driving. I don’t think either of them are trying to design a system for those conditions.

    On a personal note, I have no interest in getting a ride in a self driving car. I do have an interest in an empty car that can drive itself. Drop myself off at the airport, valet parking downtown, easier to share one car per household, river shuttling, through hike shuttling - I would use it a lot. I understand the more profitable goal is taxi services, but I don’t want that. So in my narrow use case, I hope Tesla succeeds since that approach can be used on personal vehicles anywhere while Waymo is strictly city taxis, which I don’t use.


  • Chess is a very complex rules game, while Checkers is quite simple. Waymo has a complex approach to self driving:

    • Expensive suite of sensors
    • High resolution maps of operating areas
    • Remote operators standing by

    While Teslas approach is simple:

    • Capture a bazillion miles of camera footage, feed into AI, profit?
    • Unpaid volunteers teach the AI safe driving
    • Car has only a basic map for routing, the rest is inferred in real time from cameras

    Waymo’s successful approach scales linearly. They have to high-res map every city they want to operate in, and they can gradually bring down the cost of the sensors. They will require fewer remote operator interactions over time.

    Teslas success is more difficult, but it scales exponentially. They already produce vehicles at scale and full control over all the equipment on board. The existing fleet would be able to participate as well. If they succeed, they may want to offer buy-backs for customers who didnt buy FSD - the cars would be worth more to Tesla than the owner.

    In both checkers and chess, the player gains super powers for reaching the other side of the board. Time will tell who reaches the other side of the board first. They are playing different games on the same board. Okay that’s fair.




  • Piwigo supports multiple users with different access rights, while Immich does not. Immich supports videos and Live Photos while Piwigo does not. Piwigo is a php application and can be installed by ftp on a basic web server and database (same requirements as Wordpress), while Immich requires a docker container. Both Piwigo and Immich have phone apps, but they differ in functionality. Piwigo is set up to upload individual photos while Immich is set up to backup ALL of your photos.




  • My takeaway from that article is mostly that primate research is a big emotional topic for some people, and maybe tech writers shouldn’t write about medical research. Do you think it would be so interesting if it was done on mice? The primate research center in Davis has been there since 1962, and it’s always been controversial. Do you think they’ve just been twiddling their thumbs for 55 years waiting for Neuralink to come along? No, that shit is routine for them. They keep doing it because primate research is still an important step before human trials.

    There is no need to ethically green light a medical procedure that is voluntary, of sound mind, and of one’s own will. It’s not your body. It’s not your life. People implant beads and magnets into their bodies and tattoo their faces. People hang themselves from meat hooks for fun. People get circumcised, and pierced. It’s all none of your business.


  • I don’t think it’s obvious at all. This is a sample size of one, and it is still working after 3 months.

    Globally, a staggering 310 million major surgeries are performed each year; around 40 to 50 million in USA and 20 million in Europe. It is estimated that 1–4% of these patients will die, up to 15% will have serious postoperative morbidity, and 5–15% will be readmitted within 30 days. An annual global mortality of around 8 million patients places major surgery comparable with the leading causes of death from cardiovascular disease and stroke, cancer and injury. If surgical complications were classified as a pandemic, like HIV/AIDS or coronavirus (COVID-19), developed countries would work together and devise an immediate action plan and allocate resources to address it.

    Implants are rejected by the immune system. Stents fail. Hip and joint replacements fail. Does that mean we shouldn’t do them?
