  • A fox of the same species was found in a much older grave in another part of Argentina nearly a decade ago. It may also have been a pet but its diet was not analysed.

    As usual, it’s more the article (and especially the headline) than the science. Here is the Abstract of the study.

    It’s much more about the specific burial and the inferences that can be reasonably drawn about South America before the introduction of dogs from the north 5k years ago. It references multiple burials with non-dog canids from across time periods in S.A., including at least one from about 4k years ago, as well as many other remains scattered in with human burials. It seems to build on existing theorizing that pre-Columbian practices might have changed more slowly than post. Then there are the statistical arguments. If you occasionally find a fox in human burials, based on the number of human burials you didn’t find, you can feel pretty confident that there were more foxes buried with humans.


  • I’m kinda sad to see it enshittify, for gamers and for those who find it fits their actual collaboration use case, but I also really hate the number forum-format communities that Discord has displaced or prevented from coalescing. Discoverability on Discord is terrible, as is having help available long term, as well as older advice and other content that helps newbies get the culture of a community. Even where the functionality exists, the general “real time” transitory feel of it reduces the quality of content and encourages people to be dicks, since it will all scroll by or be forgotten (if streaming) in a few moments anyway.

    Horses for courses, and my old-ass X-ennial self thinks Discord has been pressed into service on a lot of courses where it’s terrible.


  • This all feels a lot like any low- or mid-range CAD suite that gets acquired by Autodesk, Siemens, or PTC. Promise enough to avoid a revolt, but start eroding with the next release.

    The educational licensing for lock-in is also par for the course. It can be done well (Rhino 3D is legendary for letting small-shop designers use their cheap edu license forever, even commercially), but generally it’s just there to maintain the supply of baby drafters and get subscriptions from employers.
















  • I am not quite sure I’d be ready to recommend it, but your more adventurous patrons may want to experiment. These keycaps are PBT, a cousin of polyester. They are not particularly pleasant smelling when heated or especially when burned, but they’re not as unhealthy as ABS (the other common plastic for keycaps) and certainly not as bad as the straight up poison gas that comes from PVC. I use a basic 5W blue diode laser, coat the keycap with an “infusible ink” pen from Cricut (most of their infusible products are polyester-based), put it in an alignment jig, then laser a raster image “low and slow.” My particular laser seems to do best when I do two or three passes at 2% power and 45mm/minute. The idea is to heat it roughly in line with the crafting heat presses without letting the heat spread and color in areas beyond the beam. I experimented with actually burning or engraving, and that sort of works, but (1) it’s stinky, and (2) the ash wipes away and you’re left with a mostly colorless letter-shaped indentation. The “dye sub” technique produces barely any fumes at all. There are a few people on youtube who’ve tried similar techniques, and quite a few who have used different heat or dye sources.

    Aesthetically, the process was only marginally successful, though I’m optimistic about the longevity, at least compared to other low-end manufacturing techniques. I’ve been using a similar set of home-lasered keycaps for about a month with little to no wear. My jig was not as good on that set, AND I tried to center the keycap legends, meaning every fraction of a millimeter was painfully obvious. These legends didn’t end up exactly where I might have liked either, but they’re all off by the exact amount (about 1mm), so being consistent, the alignment isn’t too bad.
