  • @gloriouscow @cr1901 For myself, with regards to dealing with the cognitive dissonance, of watching technologists I personally know and admire adopt LLMs (some of which are on here, too, and who I am somewhat embarrassed to say have seen my unhinged anti-AI posts 😅):

    I think this has been much easier for me to deal with, because my personal observation for a long time has been that technologists have a very weak sense of ethics. Both in the sense of having good ethics that I agree with, and in the sense of having thought about the subject of ethics at all. Most technologists have not sat down and decided what their moral boundaries are, and what the relationship of their own morality is to the technology they use or develop. Even very skilled ones that I have learned a lot from. Most people are content to think that technologies are value-neutral, and are content to follow the trend of what everyone else is doing.

    I have observed brilliant technologists, long before LLMs, shrug at the ethics of many other things, so for me it is entirely believable that they shrug at the ethics of this, too. I don't think many of these people are inherently morally bad, but I do think that they just don't care. This is bad because I do think that people just following the trend into widespread AI adoption is an ethically bad outcome. However, I also think that as AI backlash increases, if the pendulum swings back to anti-AI being the norm in software: they will follow as well.

    It is also the sad truth that for minority women in many computer fields, we must work with brilliant peers who are not necessarily bad people, but who by way of their privileged position in life will say and do ignorant things. We must see someone saying something hurtful, but not make a fuss about it, because it's not worth the time of having to personally educate that person, to deal with the backlash, or to be labelled as a "confrontational" person. And we must do this as well, for brilliant colleagues and mentors and people we admire, and that we learn a lot from. So in that sense, I am very well practiced at this kind of cognitive dissonance - I do it in order to preserve a career.

    I hope this is maybe a little helpful for you, though this is only my personal experience. And if you do take a break, I hope it is a restful and rejuvenating one!

  • @gloriouscow @lritter also I recommend # macrophotography (and the various non-english equivalents) though fair warning it has the occasional closeup on insects. my wife introduced me to that one last night :)

    Making a Bladeless Tesla Turbine Generator in LegoThe Tesla turbine is a bladeless centripetal-flow turbine invented by Nikola Tesla in 1913, using the boundary-layer effect rather than having a stream of gases or a fluid impinge on blades. Recently [Jamie’s Brick Jams] constructed one using Lego to demonstrate just how well these turbines work compared to their bladed brethren.Since it uses the boundary-layer effect, the key is to have as much surface area as possible. This means having many smaller discs stacked side by side with some spacing between them.Interestingly, the air that is directed against the turbine will travel inwards, towards the axle of the discs and thus requiring some way to vent the air. In the video a number of design prototypes are tested to see how they perform before settling on a design suitable for a functional generator.The first discs are printed in PLA with an FDM printer, which are put on a shaft with 1 mm spacers. What becomes clear during testing is that these turbines can reach ridiculous speeds, but torque is really quite weak until you hit very high RPMs, well beyond 10,000 RPM. This is a bit of an issue if you want to drive any load with it, especially on start-up, but managed to propel a walker robot as a quick torque test.After all that testing and experimenting, the right material for the turbine discs was investigated, with PLA pitted against ‘PLA tough’, PETG, PC and TPU. Of these PLA Tough got the best results in terms of RPM at the same air pressure. This was assembled into a basic generator, but the turbine struggled to generate enough torque.Here the solution was to create a custom generator that would be much easier to spin up. To this was added a much larger turbine with 0.3 mm thin discs, using which ultimately some power could be generated, along with a considerable amount of torque. To adjust the RPM into the generator from the turbine a CVT initially was used to provide a gradual adjustment, but this had to be replaced with metal gears.After this change the generator was good enough for a power output of about 14 Watt at 30 V with 85 PSI as input. Which is more than enough to charge a smartphone or light up a big LED panel. The design files for all of these turbines are provided on MakerWorld, such as for the big turbine.Although Tesla turbines never made much of a splash as turbines, they are quite nice as pumps that can take a bit of abuse, including ingesting debris that would wreck other types of pumps. As a turbine they remain a fun hobbyist toy, with us covering various designs over the years. Take for example this one from 2011 based on HDD platters, or a micro turbine out of metal.youtube.com/embed/f65jOURRJKg?…hackaday.com/2026/03/13/making…
