  • Is your printer network attached and scanning via flatpak packages?

    Network printing works fine, USB printing and scanning works also, it is just anything having to use saned that flatpaks can’t seem to use

    I have hopped through multiple distros and I have never once had scanning not work on a “normal” one after correctly setting up saned. Only bazzite because of the flatpak/system split (also why any embedded programming needs distrobox)







  • I mean, that is extremely easy to answer.

    1. It was an otherwise-wasted material that is already bonded, minimal tools needed for processing,

    2. In colder climates, fur was already attached to the leather which means that warm clothes could be crafted easily, fast, and by gathering all of the materials at one place. In early historic times, growing suitable plants and having the capacity to process them, strip them, straighten them, and weave them was not always possible and would be a full time job where it was, which means less time working in agricultural fields. Plus, animal fur has bigger growing seasons and is much warmer than any plant alternative.

    The real answer for the modern world is that leather is a byproduct of the very shitty industrial meat industry. The meat industry already has more leather than they can get rid of and it regularly goes into landfills. From an environmental standpoint, it is much better to use the leather than almost all other materials used for those tasks which burn oil and use oil to create them (every leather alternative is simply shitty petroleum-based non-recycled plastic, every one). From a moral perspective it is shitty to give more money to the meat industry, but they make the vast vast majority of their profits on the meat and not the hides. If everyone switched off of leather right now, the same amount of animals would be brutally murdered, but instead their hides would be dumped in landfills and the ocean after stripping it off of the meat.

    This isn’t even getting into waterproofing. Almost all clothing waterproofing is petroleum or animal oil based (wax is either petroleum or harvested from bees) except for natural rubber which also has a bunch of negatives.



  • I have written a more detailed comment on it before, but 2d printing is much more technically complicated than 3D printing, and the resolution is literally an order of magnitude difference (0.2mm vs <42um) and the printer has to print full color on any surface with microdots in a very very short time. People would throw the printer out if it took 10 minutes for a single paper like a large first layer takes in 3D printing.






  • ICs, passives, and transistors. /thread.

    There are 2 big IC designers in Europe: Nordic and ST, but I believe all of their production is in China and Taiwan. If trade crashes, we have the IP, but no way to manufacture at scale. IMEC here in Belgium has 4 small fabs, but there isn’t that much else and the workforce is expensive as fuck which is why they do research IC’s almost exclusively.

    We have a lot of camera IC designing in the EU also, but they are almost all fabless. Luckily we have ASML who know everything technical about IC manufacturing.

    We have less knowledge on how to actually mass produce ICs anymore efficiently even though we create all of the tools and methods here because everything is done in the east that will see any volume production. PCBs and assembly are already 2-3x as expensive.

    In my opinion, we need huge subsidies to get component and IC scale fabs here.


  • The few things I don’t like about flatpaks (which become a problem on atomic distros that use almost all flatpak by design):

    • Some types of embedded development is essentially impossible with flatpaks. Try getting the J-link software connected with nrftools and then everything linked to VScodium/codeoss

    • Digital signing simply doesn’t work, won’t work for the foreseeable future, and is not planned to get working,

    • Flatpaks sometimes have bugs for no reasons when their package-manager counterparts don’t (e.g. in KiCAD 8.0, the upper 20% or so of dialog boxes were unclickable with the mouse, but I could select and modify them with the keyboard, only the flatpak version)

    • The status on whether it is still being actively developed or not (at least I hear a fair amount of drama surrounding it)

    But besides those small things, it seem great to me.


  • How it works for some people is the chest strap would be detected by the fitness app (polar, strava, run keeper, opentracks, etc…) and then the activity would be recorded with the chest strap. Then the activity is either synced with google health connect or google fit, apple health, etc… So it shows up in your watch app overview.

    “Smarter” smart watches I think can also connect themselves to the chest strap instead of the phone and the heart rate from the chest strap would “override” the watch’s that it then sends to the app, so you don’t have to sync with an external app. Though there might be more problems with compatibility even though all chest straps should use the standard Bluetooth “Heart Rate Service” to be completely interoperable.
