  • Like other commenters have said, start by asking the upstream developer (whether that’s by sending a message with a link to the fork or by sending a mega-PR that says you don’t expect it to be merged as-is in the description). They should be the best judge of how they’d prefer to handle it. The thing I’d add is that you should try to avoid taking it personally if their preferred approach isn’t one you think is a good idea. Sometimes good fixes end up never merged because of disagreements becoming too heated even if everyone’s basically on the same page about the fox being good. There’s also a decent chance that your refactors are things the upstream developer explicitly doesn’t want and would otherwise have done them themselves and implemented the same fix, too, or they don’t agree that your fix is good enough. They won’t want to be on the hook for maintaining contributions that use approaches and code style that they don’t like, and that’s okay. They also might know something you don’t about their project that would make something that’s obviously a good idea to you obviously a bad idea to them.

    Basically, just try and remember that if it’s a hobby project, it makes progress when the maintainer is having a good time, and gets abandoned when they’re not anymore, so try and avoid making a mess and having arguments when they’re the one that’ll have to deal with any fallout from any mistakes.


  • Something I’ve not seen mentioned here yet is that one of the reasons it’s such an effective way to make money is specifically because loads of people are buying into it. When you buy a stock (or a derivative like an S&P 500 index tracking fund), it increases its price. If you’re just one person with a normal-person amount of money, it won’t be enough to register, but if you’re part of a group of millions of people, or an investor with billions at your disposal, it’ll make a visible difference, and if people see that happening consistently, they’ll want to join in and there’ll be a positive feedback loop. It only stops when there’s a big enough panic that lots of investors can no longer afford to maintain their investment and have to sell at the same time, and then you can even get a positive feedback loop in the other direction when people see the price plummeting and decide they need to sell before it plummets any further.

    Stocks are supposed to represent the value of a company’s current assets and expected future profits, but this kind of feedback loop muddies the water. With something like Bitcoin, which intentionally has no inherent value, because enough people have agreed to pretend otherwise, it’s gained effective value, and can be exchanged for money, or in some cases, goods and services. That’ll remain the case until everyone agrees that they don’t want Bitcoin, so could go on forever.





  • This is silly. Everyone knows that DRY is telling you that if you do the same sequence of mouse clicks three times in a row, you should spend the day writing a script to automate the task instead of quickly finishing what you were doing by doing the same sequence of clicks a fourth time. If you are supposed to apply it to the code you write, then there’d never be boilerplate-heavy languages like Java.


  • That’s reasonable, but the market’s already flooded with generic controllers at various price points and degrees of quality. If the idea’s to make money, the new design won’t do brilliantly as things like the awkwardly-placed trackpads will increase manufacturing costs without being a killer feature that makes most people prefer to spend more on this particular controller. If the idea’s to make something viable that hadn’t been before (which is what Valve normally seem to go for), then this isn’t serving the discontinued Steam Controller’s niche as effectively as the original did, and isn’t serving any new niche, either.

    By the way, the thing they were trying at the same time as the original Steam Controller was the Steam Machine, not the Steam Box. It also kind of did work, as the couch PC gaming part mostly happened, but it took a decade of improvements to Proton and abandoning third-party hardware manufacturers before Linux-based console-like PCs became viable in the form of the Steam Deck. Ten years ago, nearly no games ran under Linux, and all the Steam Machine manufacturers were just changing the logo on one of their existing prebuilts and charging an extra $100 not to install Windows on it, so you were better off with any other desktop.



  • I’m a big Steam Controller trackpad user, and I already nearly never use my Deck trackpads because they’re too low down. This new one just looks like a normal controller with extra bulk, and nonsense in the area no controller except the N64 used because it’s not where most people grow fingers. I guess it’ll at least have paddles, but they’re hardly a unique feature these days. I really just wanted the existing one again, but with more paddles, an option for an integrated battery, USB-C instead of micro B, and an official supply of replacement thumbsticks instead of having to bodge in 8bitdo ones that aren’t quite the same shape.



  • I think the main draw of a moving vat is that you can tilt it during the film-part separation, so it concentrates the peel force in a line that passes over the part instead of having it spread over the whole thing and needing more force which could warp the part or stretch the film. That should mean you can get away with replacing the film less often. If the film isn’t replaced often enough, it can make the print quality worse, or tear and leak resin into the printer where all the LEDs are, which will kill the printer.

    I think all Elegoo’s machines have at least some Chitu guts, and Chitu-free machines tend to make that their main selling point (and also cost a chunk more than equivalent Chitu-based ones).

    That’s not relevant to being a tankie as the US, Israel, and other states backing Israel, aren’t claiming they’re building communism or are the successor state to another which claimed to be building communism. It’s the part where communism is an excuse that means the bad things didn’t really happen and would be fine even if they did that makes tankie-ism its own distinct thing.



  • I’ve definitely noticed less shininess than the same filament was getting at the same temperatures on my previous printer, except for the first layer. As the first layer prints without part cooling, my guess is that the extra part cooling versus the other printer means it’s setting before it’s had time to self-level. If that’s right, then turning down the part cooling (and then also the speed so you can get away with the reduced part cooling) would make things shiny again. I’ve not bothered investigating that, as most of what I print is either functional, where I wouldn’t care about shininess, or gets painted, where any shininess would come from paint or clearcoat.


  • As someone who’s just spent half an hour reading Wikipedia thanks to this thread, I can now dispense a summary of what I read to make it feel like I didn’t just waste a chunk of time I should have spent in bed by wasting another chunk of time I should be spending in bed.

    Fats are made out of fatty acids, which are carboxylic acids with a longish carbon chain. A saturated fatty acid only has single bonds between carbon atoms, a monounsaturated fatty acid has a single double bond somewhere in the chain (and these are sometimes things that turn into buzzwords, e.g. omega three oils are ones where there’s a single double bond three along from the end of the chain), and a polyunsaturated fatty acid has more than one double bond.

    Single bonds in a carbon chain can only be one way around, so you don’t get isomers of saturated fatty acids, but double bonds in a carbon chain can be in either of two orientations. If the hydrogens are on the same side for both sides of the bond, that’s the cis orientation, and if they’re on opposite sides, that’s the trans orientation. Most natural unsaturated fats are cis, so they generally don’t get explicitly labelled as cis fats, and just the trans ones get the extra label. Notably, though, vaccenic acid, which is about 4% of the fat in butter, is trans by default, so it’s cis-vaccenic acid that gets the extra label.

    Unsaturated fats tend to be more liquid at room temperature, but can be made by growing cheap vegetables. They also go off faster as free radicals can attack the double bonds. Saturated fats tend to be solid at room temperature, but mostly need to come from animals or more expensive plants (palm fat is an exception - it’s cheap and mostly saturated). It’s therefore desirable to use industrial processes to artificially saturate fats, and we can do that by heating them up and exposing them to hydrogen in the presence of a catalyst like Nickel. You don’t necessarily want to fully saturate your fat, though, so might stop part way, and if you do, unless you intentionally tweak the process to avoid it because it’s the 21st century and you’re legally obliged to, you get some of the partially hydrogenated fat switching from cis to trans.

    Over the course of the last century, we realised that (except for a few like vaccenic acid) trans fats are harmful in lots of exciting ways, e.g. messing up cholesterol, blocking your arteries, and building up in your brain. They’ve therefore been banned or restricted to certain percentages in a lot of the world. You can get a similar effect by fully hydrogenating things to get safe (or at least safer) saturated fat and mixing it with the unmodified fat, or by switching everything that used to use hydrogenated vegetable oil to using palm oil, which is one of the driving forces behind turning rainforests into palm plantations.

    Apparently, this was twenty five minutes of writing, so I’m nearly up to an hour of thinking about fats.
