  • Unless other situations where the established technology wins due to inertia, sodium ion batteries have two benefits that make them interesting regardless:

    Firstly, they are safer. A punctured sodium ion battery doesn’t catch fire, which massively simplifies safety design. That makes them very attractive for certain scenarios, especially ones where density is a secondary concern. That in turn means they get further development money instead of withering on the vine.

    Secondly, they require fewer hard-to-obtain materials, which makes them attractive from a strategic perspective. This one should be less important than the safety factor but it’s also relevant.

    I’m pretty sure we’ll actually see wet sodium cells in the wild if they are actually practical. Sodium ion tech is already being commercialized and if this brings it within the same ballpark as lithium ion then it becomes a very interesting choice for vehicles due to instant crash safety gains.







  • I mean, I can see a case for not wanting to play dragnet at a mere request. You don’t want any random guy and/or agency to be able to have you to help them track down someone they only have a picture of, no matter how much they pinkie swear they’re doing it to protect that person.

    That’s getting awfully close to sharing PII. You generally want to see a subpoena for this stuff and with good reason. Meta are, oddly enough, not being actively scummy here. (One can of course argue about all the other times when they don’t give a shit; the bigger picture is definitely super scummy. But for this in isolation they actually have a valid reason for their behavior.)

    What might work would be a standardized, streamlined process where the police can ask the company and if the company says the request is reasonable they can apply for an expedited subpoena to allow legal access to the information. Agreement by both would be necessary to give more opportunities for due diligence. This process would also have to have a very limited scope in order to make abuse harder.




  • My high school had a few unusual traditions around graduation time.

    The first related to our director, a man who gave his 100% on official school business and then gave another 100% on all of his hobby projects around the school. It wasn’t that we had something like an apiary or a pond biotope. We had an apiary and a pond biotope and a herd of goats and a tiny vineyard (in an area mostly unsuitable for wine) and a shelter for emotionally disturbed aras. In a public school. And all that besides him being a highly respected director and teacher who epitomized the definition of “strict but fair”.

    So at some point the students started to express their gratitude by giving the school presents upon graduation, usually themed around the director. The gym sported a Jurassic Park sign, except with the name of the school and with the profile of the T-Rex replaced with that of the director. In another year someone had contacts with the roads office and got something that looked like an official city limits sign made, except that it identified the school along with “administrative region <director’s name>”. Very cool; he took that one with him when he retired.

    Another tradition is somewhat common in the region: The “chaos day”, effectively a formalized graduation prank. At my school, it worked like this: The evening before, the students were given a copy of the keys to the school and free access to the school grounds to prepare. The next day they had to prevent the teachers from entering the building; if a teacher got in, school would resume as per normal. The teachers had a fairly good track record. Many graduating classes failed to account for the fact that the teachers had bolt cutters. One time they didn’t account for an obscure window at the back of the school, which happened to be an emergency exit and had an external lock.

    My year didn’t take any chances. I come from a fairly rural area so we had farmers in class and those farmers had forklifts and hay bales. By the time school was supposed to start, all entrances to the building had solid walls of hay in front of them. We also immediately cashiered any teacher who entered the school grounds and forced them into party activities. I have fond memories of hearing my class teacher horribly butcher Oh my darling, Clementine before wandering off to listen to the school band play Hurra, hurra, die Schule brennt.



  • Oh yeah, same here except with a self-hosted LLM. I had a log file with thousands of warnings and errors coming from several components. Major refactor of a codebase in the cleanup phase. I wanted to have those sorted by severity, component, and exception (if present). Nothing fancy.

    So, hoping I could get a quick solution, I passed it to the LLM. It returned an error. Turns out that a 14 megabyte text file exceeds the context size. That server with several datacenter GPUs sure looks like a great investment now.

    So I just threw together a script that applied a few regexes. That worked, no surprise.




  • Those investments should definitely come with strings attached. But there’s a lot you need to invest into.

    • Fabs cost a shitload of money and are slow to build. If you want to be able to be independent from Taiwan in ten years you should invest a couple dozen billion bucks in fabs right now. If you want a company to invest that money for you, you need to guarantee that they’ll see a good ROI, which means you probably sign a contract to buy tons of hardware that won’t be made for another decade.
    • Fabs need a lot of land. If you want to start building ASAP you need to expedite assessments and acquire land quickly (and though eminent domain, if necessary). That ain’t cheap.
    • If you want a qualified workforce available you need to not only invest in making training available but also in making it appealing enough that they’ll start training before the jobs are even there. Advertisement like that costs money, as do stipends.
    • In fact, add research grants to the pool because you’ll want both basic research to be done in the field and skilled researchers to be available for cross-hiring by your companies.

    You’ll need to keep (some amount of) the money flowing at least until the industry can be independently competitive on the world stage. Mishandling your burgeoning industry can mean that all that investment money and a large number of jobs suddenly go up in smoke.

    Note: All of this assumes that you’ll buy your manufacturing equipment from established, potentially foreign companies like ASML and Zeiss. If you want to make that stuff domestically as well you can probably add another hundred billion bucks and a decade or two of very dedicated catch-up to the bill.





  • I had avoided it until late last year when I had to reinstall a friend’s borked install after it had somehow managed to shred its registry hives.

    Holy shit. That installer is an embarrassment. First it couldn’t get past the first reboot until I found out that you can set it to use what looks like the Windows 7 installer for the first steps. Then I had to deal with a dog slow installer that needs half a dozen reboots for some unfathomable reason. Then an endless cavalcade of sales prompts, including one for an Office subscription where they try to hide the price from you. All to end in, well, Windows 11.

    I simultaneously installed Fedora Kinoite on his old laptop. I don’t think the Fedora installer is one of the better ones but it was so much easier and faster to set up the machine that it was almost comical.

    Seeing both systems side by side really drives home just how clunky Windows is. And how Microsoft installers are barely better than they were 15 years ago, but now they have ads.


  • Or double down on AI. Then double down even harder.

    • Make the use of Copilot mandatory; simultaneously heavily monetize it to instantly turn the AI division into a profit center.
    • To that end release the successor to Windows 11, a cloud-only offering that replaces the taskbar with a Copilot instance which launches programs for the user. Downplay any accusations that the new Windows Live 365 With Copilot is just a rental Windows 11 with the taskbar hastily hacked out.
    • Don’t forget that Windows Live 365 With Copilot does not include a subscription for Copilot, which must be booked separately.
    • Get all of your customers to switch by immediately dropping support for all previous Windows versions, “migrating” their support windows over to Windows Live 365 With Copilot. Corporate customers, which have gone all-in on Azure, will need years to migrate off the Windows ecosystem, which means excellent short-term revenue.
    • Make sure that Windows Live 365 With Copilot can only save to OneDrive to make it maximally hard for those customers to get their data out.
    • Hope that the current world order disintegrates before the massive exodus of customers ruins the company.
    • Whether or not it does, turn off your business phone and spend the next five years doing massive amounts of cocaine on a private island in the South Pacific.
