  • The “specific program” I have trouble with is Autodesk Fusion (formerly Fusion 360). There are projects that try to run it through Wine, but there’s a specific function that isn’t implemented in Wine right now that Fusion relies on as part of its authentication service, so it won’t log you in correctly, at least on the default Mint install. I think at least one of the relevant functions is currently in the Wine beta, so it may work again in a bit–I did manage to get it working briefly at one point, but I somehow screwed it up again subsequently. (I may just have forgotten how I launched it…I think I have two versions installed at this point, the Flatpak and the Snap install.) But even when it worked it was slow and janky in a much more severe way than when it runs natively on Windows.

    The “specific program” my dad is interested in is Hesuvi, a piece of headphone virtualization software that also does equalization and crossover. At some point I identified a program I though would work on Linux as an alternative, but I would want to test that before committing to switching his computer over from Windows, and I haven’t got around to that yet. Other than that he mostly uses Zoom, and I think I tested that and it worked okay in Mint, though my memory is a little weak on that too.

    I dunno. Basically everyone has their own little patterns they use with their computers, and switching to Linux requires changes to those patterns. It’s an adaptation. That’s not to say it’s not worth it–for a ton of people it probably is. But I’m not sure my aging parents can do it, and thanks to Fusion, I’m not sure I can do it either, because I just don’t have a good replacement.

    The other option I’m looking into is Windows IoT LTSC. That omits a LOT of the problematic bullshit.

    I’ll figure something out before the end of support, anyway.


  • You definitely can start this way. When I started, I got some help from a physical therapist–I had really messed up my back, and in addition to helping with the acute issue, they also selected a set of exercises and numbers of reps for me that I could do at home, and that was a great starting point for my exercise routine. It was pretty short and focused, so it was easy to find time to do it every day, and the practice of keeping at it was really helpful. My health insurance covered most of the cost of the physical therapist; I had to pay a copay, but even then it was just a couple times a week for maybe two months, so not exorbitant. Insurance is generally willing to help with this stuff for a little while because they know that if your health improves, it’s likely to reduce their future costs. So it’s worth looking in to whether yours would help with something like that just to get yourself going. I don’t think you need to have an acute problem to take advantage of that; I think having a specific goal for improvement is adequate. (They want measurable goals, like “I’d like to be able to jog five minutes without getting winded,” or that sort of thing. I believe mine was “I’d like to be able to spend a day out walking around a garden with my family without being laid up the next day by my back.” Which reflects where I was at the time. But, y’know, anything that reflects where you currently are, and something that you might be able to achieve in a six-to-eight-week timeframe, is probably a good goal.)

    Doing that regularly also got me listening to my body, and that got me to gradually expand my routine–I eventually understood that some of my back issues were propagating up from hip issues, so now I work on those, and some of those are coming from limited ankle mobility, so I’m also working on that, and working on that has got me doing “goblin squats” that has gotten me to stop thinking of dumbbells as something to avoid. I’m also getting closer to being able to do pull-ups; I got a pull-up bar because just hanging from a bar sometimes can really help with a bad back, but at some point I started thinking about how much more I enjoyed moving when I was a kid and took gymnastics classes, and back then I actually had the strength to do things like pull-ups. So now I can do some resistance-band assisted pull-ups, and hopefully in a year or two I’ll be able to do the proper thing.

    Picturing enjoying movement is something that really motivates me, actually. Like, I used to enjoy biking and ultimate frisbee. I don’t, now, but I think I might enjoy them again at some point. I think I might also enjoy parkour, if I can get into that kind of shape, but I recognize that may not be an achievable goal at this point. I had a kind of enthusiasm for brief bursts of very intense movement, like sprinting up a flight of stairs two at a time, or climbing up onto a loading dock in a single giant step.

    At this point I do a basic set of dumbbell weight exercises, squats and lunges, push ups, a back stretching and exercises routine, assisted pull-ups, and a walking/running aerobics routine. It’s not a ton, but I’m really in vastly better shape than I was when I started a few years ago. I do have a handful of equipment–the dumbbells, a floor mat, a couple of foam rollers, an exercise ball (for trunk lifts, which are good for a weak lower back), a doorway pull-up bar, some resistance bands that I basically just use with the pull-up bar, and the biggest thing is an elliptical machine for when the weather is too bad to do the aerobics outside. There are ways to do it without a machine, like jogging in place or doing rapid shallow squats, but the machine is kind of nice–it’s hard to explain, but it really helps to have the exercise take place in its own little isolated space, or even just in its own mental space. I actually also have a little lighted sign that I made (it’s a recreation of the neon sign for an exterminator’s in my home town that always tickled my fancy back then–it’s got a giant neon rat in the middle) and I like to turn that on in my room specifically while I do my exercises there (everything other than the aerobics and pull ups), just because it kind of marks out the distinction of exercise time. It helps make it a ritual, and that helps make it a habit. As I say, hard to explain, but it feels like it matters.

    I will say, this routine has also helped me lose some weight. I’m down about 45 lbs (~22kg) from this time last year. That’s mainly down to diet changes, but I did ramp up my exercising while doing this to be sure that I was losing fat rather than just losing muscle. I’m still a lot heavier than I’d like, but I’m definitely proud of how far I’ve come. I’m improving in other measures, too, like my resting heart rate is down from around 100 to around 80, which, again, is not where I’d like to be, but represents movement in the right direction.

    So, I do think the physical therapist helped a lot with getting me started, but most of my work I’ve done at home, and without too much in the way of equipment.

    Would I have done better, faster by going to a gym? I dunno. I definitely know that friction is a big factor. If it’s hard to actually go do the thing, then it’s easy to make excuses not to go do the thing; needing to actually travel to a gym definitely counts for that. There’s kind of a balancing act in making my routine easy enough and pleasant enough that I’ll actually do it, but also challenging enough that I’m still gradually improving. Sometimes I need to let myself slack off at something a little as an incentive do just do the thing. And sometimes once I’m actually doing the thing I don’t need the slack after all.

    Bit of a rant, I guess. Sorry, it feels like so much of this stuff is, like, techniques for outwitting part of my own brain, and it feels like those are things other people might be able to use, but I’m not sure how transferable they really are. Hope it helps.

    Good luck with your journey! I know I’ll need luck on mine.


  • The one I thought was a good compromise was 14 years, with the option to file again for a single renewal for a second 14 years. That was the basic system in the US for quite a while, and it has the benefit of being a good fit for the human life span–it means that the stuff that was popular with our parents when we were kids, i.e. the cultural milieu in which we were raised, would be public domain by the time we were adults, and we’d be free to remix it and revisit it. It also covers the vast majority of the sales lifetime of a work, and makes preservation and archiving more generally feasible.

    5 years may be an overcorrection, but I think very limited terms like that are closer to the right solution than our current system is.




  • I think so? It’s section 3.2 of the paper: https://www.tandfonline.com/doi/full/10.1080/17452759.2024.2404157#d1e604

    They don’t talk that much about current in particular; figure 5 only shows the resistance in the regulated output path as a function of the voltage on the control path, which isn’t enough to actually say whether there’s specifically current amplification. (Also, the gain would be negative; does that matter?) But they do discuss the fact that the output channel is much wider, which strongly suggests it’s able to pass more current (since they mention the resistivity drops as the cross-sectional area of the trace increases). The wider trace is one that wouldn’t have the fuse behavior on its own, because the resistivity is too low for it to heat up enough to trigger that at the voltages they’re using, but the close proximity of the very thin fusing wire of the control signal is enough to cause a nonlinear resistivity change in the output path as well. I think that means they’re using a single voltage for both kinds of path, and that the control current is thus lower than the output current because the resistance on the control path is higher, but I’m not certain. I am not an electrical engineer, just an enthusiastic amateur.


  • They did do the thing that HewlettHackard is describing. Check out the AND gate in the linked article. The input paths are short and use small wires, but also cross the larger paths that normally link the output to ground. If both are active, the paths to ground are interrupted, and the resistor to VCC pulls up the output. So they did make logic gates. In the paper they also demonstrate NOT and OR.

    I gather there’s a technical sense of “active” that’s used in electrical engineering that might not apply here, but to someone like me, with only a tinkerer’s knowledge of components, logic gates seem like enough to justify the term in the headline.



  • Citizens United would be a decent candidate. Once it was established that donations were protected political speech, it effectively legalized bribery, and made oligarchy essentially inevitable. Most of the missteps since then have been motivated by folks trying to simultaneously play to populist talking points but also placate billionaire donors. The left needed an actual positive message, like the kind Bernie Sanders was pushing, that would energize folks and unite the overeducated with the working class, but that was never going to be acceptable to the donor class, and so candidates like him always had to be shoved aside for someone who would clearly cater to corporate needs. And someone who would clearly cater to corporate needs was always going to be a really tough sell and not really a solution to the needs of the moment.

    That doesn’t really account for the rise of the tech bro fascist accelerationists like Mencius Moldbug and the Dark Enlightenment, which is a big part of the current moment and accounts for how the far right was able to hoodwink some billionaires into voting for a social collapse that seems very likely to hurt them also. But Citizens United still seems like a fair candidate for a point at which some of the last paths away from this outcome were foreclosed.



  • I think the issue is with it being just a single wall. The slicer tends to have some trouble with that.

    My first thought was just to model the return paths as well, making it a loop, print that in vase mode, then just cut away the unwanted parts. My second thought was to wonder whether there would be a way to use post-processing to set the extrusion to zero for those particular paths, maybe using the multicolor features, and thereby avoid printing the extra area.



  • I think it’s reasonably likely. There was a research paper about how to do basically that a couple years ago. If you need a basic LLM trained on a specialized form of input and output, getting the expensive existing LLMs to generate that text for you is pretty efficient/inexpensive, so it’s a reasonable way to get a baseline model. Then you can add stuff like chain of reasoning and mixture of experts to improve the performance back up to where you need it. It’s not going to be a way to push the state of the art forward, but it’s sure a cheap way to catch up to models that have done that pushing.
