  • That sounds pretty great. My impression is that relatively little code actually runs that often.

    but with none of the footguns of manual memory management, no garbage collection pauses, but yet also no evil stepparent style borrow checker to be beaten by.

    That part sounds implausible, though. What kind of memory management are they doing?


  • Enjoyer of political violence falls victim to political violence. Oh no! /s

    If these guys were themselves pacifists who prided themselves on giving every idea a fair hearing, I guess I would have a problem with any assassinations. As it is, there’s just one side trying to unilaterally manifest a certain level of civility. One that unfortunately doesn’t seem to exist.

    Edit: I believe this complies with rule 6. Lack of concern about violence isn’t the same thing as advocacy.


  • If AI ends up running companies better than people

    Okay, important context there. The current AI bubble will burst sooner or later. So, this is hypothetical future AGI.

    Yes, if the process of human labour becoming redundant continues uninterrupted, it’s highly likely, although since CEOs make their money from the intangible asset of having connections more than the actual work they’ll be one of the last to go.

    But, it won’t continue uninterrupted. We’re talking about rapidly transitioning to an entirely different kind of economy, and we should expect it will be similarly destabilising as it was to hunter gatherer societies that suddenly encountered industrial technology.

    If humans are still in control, and you still have an entire top 10% of the population with significant equity holdings, there’s not going to be much strategy to the initial stages. Front line workers will get laid off catastrophically, basically, and no new work will be forthcoming. The next step will be a political reaction. If some kind of make-work program is what comes out of it, human managers will still find a place in it. If it’s basic income, probably not. (And if there’s not some kind of restriction on the top end of wealth, as well, you’re at risk of creating a new ruling elite with an incentive to kill everyone else off, but that’s actually a digression from the question)

    When it comes to the longer term, I find inspiration in a blog post I read recently. Capital holdings will eventually become meaningless compared to rights to natural factors. If military logic works at all the same way, and there’s ever any kind of war, land will once again be supreme among them. There weren’t really CEOs in feudalism, and even if we manage not to regress to autocracy there probably won’t be a place for them.




  • Wow, exactly the kind of thing I was looking for posted in 3 minutes. Amazing!

    It goes into pretty poor detail on the actual medium itself, unfortunately. How fine were the particles? What was the exact recipe that worked?

    Some of the commenters had much more interesting things to say:

    @verdatum

    As a kid, the thing that blew me away was Tim Hunkin’s The Secret Life of Machines. He had an episode on the cassette player/recorder where his partner demonstrated that cassette tape could be emulated by taking Scotch tape patting it into a or iron-oxide and running that result over the tape heads. “This is the sound of my voice recorded on sticky-tape and rust.” that revelation absolutely blew my child mind.

    @DerWahreTee

    I might be able to give you some advise here. I am a material chemist and I professionally work on polymer coatings similar to the one your using. I think your problem is at least partially a poor particle distribution and uneven coating thickness. The particulate you are trying to suspend needs to have a particle size <1mikrometer. When you buy such particles as a dry poor they have agglomerated during the drying process I.e. they have become stuck together in unevenly sized chunks. This creates also makes the particles less evenly spread throughout your coating than it visually appears. To break up these agglomerates you actually need a tremendous amount of kinetic energy which your magnetic stirrer can not do. Also the Mayer-bar isn’t really the ideal method to apply your coating even if you can’t see it it is notoriously uneven on a microscopic level especially when applied by hand. Ideally you would use a spincoater which could apply you coating more evenly. Hope this helps

    @fiscap

    Commercially produced floppy disks go through a magnetic alignment process, while the coating is still wet. I think the magnetic particles in your solution/suspension are too random to produce a consistent and reliable flux transition during the write process. If you do try this again, try to figure out a process to align the particle orientation and keep it in place until the coating fully cures.

    @stamasd8500

    I am pretty sure the magnetic material that you used is part of the problem. You don’t give a lot of detail on what exactly you used, but in the video you say “black iron oxide” so I infer you used magnetite, Fe3O4. That is not the correct material to use. I did some research not long ago into magnetic materials used in the period, and even recreated some magnetic material after poring through some research papers and patents from the 1950s to 70s. The magnetic material used on floppy disks is a type II or III material (as defined for magnetic tapes) so either a cobalt-doped gamma-Fe2O3 or a chromium dioxide-based material. Magnetite is not correct as it doesn’t have the required saturation flux and coercivity. I have in fact recreated in my basement lab a type II material, a cobalt-doped gamma-Fe2O3 ferrite which would be appropriate for that. It’s not difficult but it requires patience and precision. And a few tools, including an electric oven that can go to at least 850 degrees Celsius.

    The last one gives me one possible place to search next. What are the numbered material types referenced?

    Anyway, if it weren’t for the sponsor, the way to make the substrate would have been just a punch, right? Laser cutting and then baking the sheets flat again felt a little unnecessary.







  • True. But, practices and stories are what a religion is made out of. The dietary laws are in the bible even if they’re interpreted as no longer applying, most of the other things that are forbidden to Christians are still forbidden, and they’re really big on charity and not worshiping other gods. The fasting is new, I guess, as is the specific style of prayer.

    I kind of have to go through the rest piece-by-piece.

    bearing suffering

    Subjective, so I’ll just leave it.

    being saved by grace

    How that’s interpreted varies massively by denomination and through history. The protestant version I was taught isn’t even the original one historically - everyone had to keep up with their confessions before the reformation.

    monogamy to one of polygamy

    I suppose there was a pretty decent divergence there, although I’m surprised to hear it as a grievance.

    conquest and slaughter

    … You’re British. It’s a Christian nation that has a certain history.

    and many rituals

    Almost everything that happens in a church qualifies as well. Some of the more American-style churches are flexible about it, and drink their grape juice out of plastic cups n fold-up chairs, but AFAIK the King’s church still keeps the old flair.

    The Muslims don’t even worship Christ.

    He’s #2 after Mohammad. It’s true he’s not worshiped though. You need a trinity to make that not idolatry, which is one of the bones Muslims have to pick with Christians.








  • For what little I’ve gathered due to separation of powers. The supreme court is just a designated authority. Why hasn’t there been any movement that just aims to de-legitimize the current supreme Court?

    Wait, what? Can you explain a bit more? Like what laws are you looking at, and are they less than 200 years old?

    At least in practice, the Supreme Court is as strong as any other American institution. Which, to be fair, is saying less and less, but the faction with all the initiative right now is not the one against racial profiling.
