  • Yeah, it can be really helpful to understand the context and the problems they were trying to solve.

    Like for example, I think a lot of pop-sci talk about Special/General Relativity is missing huge chunks of context, because in reality, Einstein didn’t come up with these theories out of thin air. His breakthrough was creating a coherent framework out of decades of theoretical and experimental work from the scientists that came before him.

    And the Einstein Field Equations really didn’t answer much on their own, they just posed more questions. It wasn’t until people started to find concrete solutions for them that we really understood just how powerful they were.

    Trying to teach yourself higher math without a textbook is nearly impossible.

    You could try just Googling all the Greek letters and symbols but have fun sifting through the hundred-odd uses of σ for the one that’s relevant to your context. And good fucking luck if it’s baked into an image.

    The quickest way I’ve gotten an intuition for a lot of higher math things was seeing it implemented in a programming language.





  • When I was gaming on Windows, the DirectX 12 implementation in every game I tried was kinda garbage.

    It usually either would just perform bad in general, or just have really bad input lag.

    The first thing I’d try whenever I had problems was switching the renderer to DirectX 11, and that would often fix things.

    In fairness, Vulkan implementations have been pretty hit-and-miss too. I think developers still just need to get used to the new execution model.

    This also was on Nvidia graphics, which may or may not have had something to do with it.


  • Despite a rocky launch, I ended up playing a fuckton of Battlefield 4.

    And Battlefield 1, while not historically accurate in the slightest, was actually a nice breath of fresh air, and a setting that hasn’t been covered nearly as much in popular media as other 20th century wars (with possibly the exception of Korea). It’s actually one of my favorites.

    Battlefield 5 just felt so… bland by comparison. They tried to change too many systems, and ended up making just a completely milquetoast game. Really disappointing for what should have been a triumphant return to the series’ roots.

    Battlefield 2042 had no soul whatsoever, and some of the worst designed maps in a Battlefield game I’ve ever seen.

    One of the maps that was available in the beta that I played was literally just a giant fucking field with hardly any cover and a hundred-foot wall for the enemy snipers to stand on top of and pick off attackers one by one. I really wish I could have been in the meeting room when they were workshopping that map, because I wanna know exactly what the fuck they were smoking to think that it would be any fun at all to play.

    I’d honestly welcome a return to formula here if it means another game like BF4 or BF1, even if most players don’t consider that “classic” Battlefield.





  • This is undeniably hilarious, but if you’ve ever seen actual dissection photos or videos of surgery, you kinda recognize that good anatomical drawings required a lot of mental effort to create.

    Imagine making a completely accurate diagram of everything in a car’s engine bay, either while the engine is running and it’s doing 70mph down the highway, or after it’s had a head-on collision at the same speed.


  • We’ve seen plenty of evidence that the current inflation is almost entirely driven by companies price gouging consumers.

    And actually, the fact that the price hasn’t increased is pretty obvious evidence of this.

    Do you think, for one second, Apple would accept any appreciable hit to its profit margin if their costs had inflated 1:1 with consumer prices? Especially when they have a perfect excuse to blame a price increase on?

    The phone may cost them a little more to make than last year, but I doubt it’s that much.

    There’s tons of elasticity built into the pricing already so that carriers can offer discounts.


  • The point is kind of moot because the phone definitely comes with the cable: https://www.apple.com/iphone-16/specs/

    The article is actually about the new AirPods. I was going entirely off the information in the comment I was replying to.

    The thing is, the iPhone 14, 15 and 16 all have the same launch price: $799 US

    Adjusted for inflation, the 14 and 15 may have cost more, but Apple is almost certainly making that money back somewhere else. Like, say, making people pay for accessories that used to be included?

    And at the end of the day, the prices consumers pay for end products don’t follow the exact same curve as the prices megacorporations pay for materials and labor. We’ve seen plenty of evidence that the current inflation is almost entirely driven by companies price gouging consumers. So it’s not really reasonable to assume that Apple’s costs have gone up 1:1 with consumer prices anyway.


  • But here’s the question: does it cost Apple $20 to make a cable? I seriously doubt it. It probably costs them closer to 20 cents per cable. So in reality, they now make approximately $20 more from every sale than they did before.

    Sure, not everyone is buying a cable with every phone. But cables get lost, they wear out, they get stolen by your kids to charge their iPhones because they broke theirs, they get chewed up by pets, etc.

    And you can bet your ass that, just like any other high-margin item, the people in the Apple store are gonna be incentivized like hell to get every customer to buy a cable with their phone whether they really need it or not:

    Do you have a charging cable?

    Is it an Apple cable?

    Are you sure you have one that’s USB-C and supports USB Power Delivery?

    And it’s not worn out?

    You say your dog chewed on it a little but it’s mostly intact and still works?

    Well, I’d recommend getting a new one anyway.

    Yeah you can get your own if you want but it’s best if you get an Apple cable.

    OK great, that comes out to $820 total. And do you want to insure your phone for $5 a month?





  • Your opinion is posited as an absolute: “This is useless”

    That’s not even correct. I said “not all that useful” and then “next to useless”. Never “absolutely useless”.

    The whole point of this feature is to provide something built into Steam that works without a whole bunch of fiddling like other recording software. It currently fails at that on Linux because the implementation of it is half-assed. That is my position. End of conversation.
