  • Disagree, if you need a custom big machine made, there are some really good people on AliExpress.

    I have had a couple of customized CNC machines custom built for a fraction of the price it would have cost to have it done over here. Even with the shipping costs it came out cheaper. And the people were really helpful, they use machines like mine all the time so they know their stuff. They offered really good advice and were excited to work with me. It’s a bit butt clenching to fork over a lot of cash and hope a big ass pallet shows up 4 months later, but they’ve come through for me every time. YMMV.

    Temu on the other hand can fuck off. It’s just a scam site like Wish.



  • Rendering a 3D scene is much more intensive and complicated than a simple scaler. The scaler isn’t advanced at all, it’s actually very simple. And it can’t be compared with running a large model locally. These are expert systems, not large models. They are very good at one thing and can do only that thing.

    Like I said the cost is fixed, so if the scaler can handle 1080p at 120fps to upscale to 2K, then it can always handle that. It doesn’t matter how complex or simple the image is, it will always use the same amount of power. It reads the image, does the calculation and outputs the resulting image.

    Rendering a 3D scene is much much more complex and power intensive. The amount of power highly depends on the complexity of the scene and there is a lot more involved. It needs the gpu, cpu, memory and even sometimes storage, plus all the bandwidth and latency in between.

    Upscaling isn’t like that, it’s a lot more simple. So if the hardware is there, like the AI cores on a gpu or the dedicated upscaler chip, it will always work. And since that hardware will normally not be heavily used, the rest of the components are still available for the game. A dedicated scaler is the most efficient, but the cores on the gpu aren’t bad either. That’s why something like DLSS doesn’t just work on any hardware, it needs specialized components. And different generations and parts have different limitations.

    Say your system can render a game at 1080p at a good solid 120fps. But you have a 2K monitor, so you want the game to run at 2K. This requires a lot more from the system, so the computer struggles to run the game at 60 fps and has annoying dips in demanding parts. With upscaling you run the game at 1080p at 120fps and the upscaler takes that image stream and converts it into 2K at a smooth 120fps. Now the scaler may not get all the details right, like running native 2K and it may make some small mistakes. But our eyes are pretty bad and if we’re playing games our brains aren’t looking for those details, but are instead focused on gameplay. So the output is probably pretty good and unless you were to compare it with 2K native side by side, probably you won’t even notice the difference. So it’s a way of having that excellent performance, without shelling out a 1000 bucks for better hardware.

    There are limitations of course. Not all games conform to what the scaler is good at. It usually does well with realistic scenes, but can struggle with more abstract stuff. It can get annoying halos and weird artifacts. There are also limitations to what bandwidth it can push, so for example not all gpus can do 4K at a high framerate. If the game uses the AI cores as well for other stuff, that can become an issue. If the difference in resolution is too much, that becomes very noticeable and unplayable. Often there’s also the option to use previous frames to generate intermediate frames, to boost the framerate with little cost. In my experience this doesn’t work well and just makes the game feel like it’s ghosting and smearing.

    But when used properly, it can give a nice boost basically for free. I have even seen it used where the game could be run at a lower quality at the native resolution and high framerate, but looked better at a lower resolution with a higher quality setting and then upscaled. The extra effects outweighed the small loss of fidelity.


  • The game is rendered at a lower resolution, this saves a lot of resources. This isn’t a linear thing, lowering the resolution reduces the performance needed by a lot more than you would think. Not just in processing power but also bandwidth and memory requirements. Then dedicated AI cores or even special AI scaler chips get used to upscale the image back to the requested resolution. This is a fixed cost and can be done with little power since the components are designed to do this task.

    My TV for example has an AI scaler chip which is pretty nice (especially after tuning) for showing old content on a large high res screen. For games applying AI up scaling to old textures also does wonders.

    Now even though this gets the AI label slapped on, this is nothing like the LMMs such as chat GPT. These are expert systems trained and designed to do exactly one thing. This is the good kind of AI that’s actually useful instead of the BS AI like LLMs. Now these systems have their limitations, but for games the trade off between details and framerate can be worth it. Especially if our bad eyes and mediocre screens wouldn’t really show the difference anyways.



  • Really I’m gonna need a source for that old timey radio claim. Because that sounds like it’s made up and even if it’s not, correlation does not mean causation.

    There is no known mechanism for non ionizing radiation to have ANY effect on the human body or individual cells besides from a warming effect. And even the warming effect is quite small, there are normally a lot of other factors that have a way bigger effect on the temperature. See the Mythbusters episode where they tried to warm a chicken on a radar emitter. The turning of the radar cooled it down more than any warming from the radar did.

    If there is any truth to claims that non ionizing radiation harms humans, physicists would be all over that. That would mean new physics in an area where there hasn’t been any new stuff for a long time now.

    But it turns out we understand it pretty well and see no mechanism for any harm to occur. In that context all of the studies that find no relation are meaningful. If there seems to be no relation and there isn’t a mechanism to do anything, why would anybody think there is anything to find? Turns out it always comes down to FUD, to further some kind of an agenda.


  • I did the exact same. Google Play Music was actually a good service back in the day. I hated it when they turned it into YouTube Music. I complained about all the broken stuff, so they gave me a home speaker for free and upgraded me to YT Premium for a year. After that year I stuck with YT Premium, since it was less than $2 extra. They also fixed a lot of stuff I complained about. Not everything, but a lot of it. I think YT Music was released a bit before it was ready. Now it still has some issues, but is mostly fine.

    Usually I watch 1 or 2 YouTube videos a day and without Premium I would most definitely not. I opened a YouTube video on a computer I wasn’t signed in the other day and it started with a 2 minute unskipable ad about crypto stuff (an obvious scam). So I closed it real fast, no video is worth sitting through that. Even with Premium I still need SponsorBlock. But with that combination watching videos is actually fun.

    Still listen to YouTube Music all day at work, so that’s a good value for money for me.


  • I’ve played this in the past because of the unique co-op feature. You can team up with another player and play the game. You both do a battle and if you win, your units can go over to the other fight to help your buddy out. It’s super fun and I played it a good number of hours with my brother. The biggest issue however was the camera, you can’t hardly zoom out. That means in co-op you can only see your own battle, you can go look at your buddy’s battle, but that means you can’t see your own battle. This sucked really bad, because you couldn’t see what worked and what didn’t and how it was going overall. For us this kinda ruined the co-op game mode, it was just like playing the game solo and sometimes you would get help randomly. We submitted it as feedback to the devs, saying in co-op you need to be able to see both battles at the same time, but I don’t think they ever did anything about it. So we’ve stopped playing it, maybe we’ll give it another go sometimes.




  • I know a lot of folk that work at MS or have worked there, they are all very good people. They are highly motivated professionals that are top in their field. MS is a rich company and they recruit the best they can. However those are not the people making any kind of decisions. And it’s a cut throat company, if the budget gets cut, you are out on your ass. At least in most of the world, where strong employee protection isn’t a thing.

    Don’t get me wrong, MS has a lot of bad apples just like any other company. Useless managers who say dumb shit and take praise for other peoples work. A leadership that doesn’t care about anything except their bonuses and the bottom line. But at least as far as the engineers go, there’s plenty of really good folk.

    People also seem to forget how huge MS actually is. And a lot of the time the different branches within the company are as far away from each other as can be. Even within the same branch one can only talk to so many people.

    Power cables are probably still useful. At least here in Western Europe the power cables I used in the 80s are still perfectly fine today. Better even, since copper was cheaper they often have more than modern cables (which shouldn’t matter if they are within spec, but still).

    Those old centronics cables on the other hand, maybe it’s time for them to go.
