Cake day: June 10th, 2023

  • I bought a Brother colour laser last year (which on the outside looks identical to the monochrome one I bought 17 years ago that lives with my parents), zero issues, which pretty much has been my experience with printers on linux (also tried a ~5 y/o & 25 y/o HP LaserJet, one being the cheapest thing I’ve ever used, other being old office equipment, think I tried the Epson ecotank and photo printer my mil has as well)


  • It’s not terrible advice tbh, even just hand sketches are solid for getting ideas down, makes it easy to translate to cad. It at least helps me think things through and the like.

    Get a few pencils with different leads (some harder stuff like 2-4H and an HB) and some nice paper and you’re good, but really anything works, totally have a mockup of my garage on a whiteboard planning where I want to put stuff.

    As for cad packages, freecad, as far as I’m aware there are some architecture workbench plugins, and there’s a tech drawing workbench. Coming back to cad after a while I found it super easy to pick back up (coming from solidworks at least)







  • Terminal usage is a tool just like GUI tools, I don’t think it’s helpful either to preload people with the belief that it’s some arcane tool that takes years before you can start using it, like anything you pick it up by doing.

    Can’t really say it’s 100% optional as a blanket case either, heavily depends on a user, my work I’ve depended on having a terminal for years, and that was even before I moved into SWE, I’ve seen lots of business developed processes put together as an amalgam of batch files, VBA/VBS, and python because they needed to put something together with what they had rights to.

    Be honest that I don’t see the terminal as a barrier to Linux anyhow, for the use case of “I browse the internet and use office programs”, you absolutely do not need to drop to the CLI, at least not for Debian or Mint, can handle installs and updates through their graphical package managers. Most people probably aren’t setting up services or the like on their machines, and if they are they already require terminal usage on any operating system.


  • Haven’t looked into it but do shops offer lube analysis services? Yeah you could send out your own sample to a lab, having it as a shop service would be way more accessible to people.

    Though, in my experience, getting people to commit can be a pain, lots of “yeah I know we have a long p-f interval and it’s super noticeable before it functionally fails, but it’s not that much effort so I’m doing needless maintenance anyhow just in case”, which end of the day you do you.









  • Found upgrades mildly annoying with GitLab, big reason I moved to Forgejo for my personal stuff. Far easier to setup and maintain for me, seems to be happy with caddy and runners are really easy to setup.

    I’m not hosting for an entire org though, it’s just me and I keep all my selfhost stuff local only, so obviously YMMV.


  • I’m a mechanical eng turned software, computing and the like are super visible but there’s been a huge amount of advancement in physical things in our lifetime, Steel in particular. By no means an expert, some of this I’ve been out of the industry for a while so just operating on memory, totally welcome any corrections!

    I’m not a metallurgist, but worked with them, there’s lots of grades out there but some of the stuff being used in automotive is seriously interesting (I think they’re boron grades but I can’t recall), needs specific treatment like hot stamping but they can easily hit into the 1-2 GPa range for yield strength once it’s processed. It’s allowed material to be rolled thinner for the same part strength so you end up with lighter vehicles.

    Coatings too have changed a lot, non-chromium passivation is a thing, galvanised materials are no longer just zinc + a bit of aluminum, there’s aluminum + silicon coatings that are supposed to offer decent corrosion resistance at high temperatures, those fancy automotive steels get coated in it for things like mufflers. Construction there were zinc+magnesium coatings starting to show up, supposed to be resistant to coating damage.

    Processing has changed a lot in a century too, steel is substantially metallurgically cleaner these days, probably actually cleaner too with more electric arc furnaces and hydrogen direct reduced iron.

    It’s oldish these days but pipeline inspection was increasingly using Electromagnetic Acoustic Transducer (EMAT) tools when I worked in that field. It let you do ultrasound inspection of steel pipes without needing a liquid medium, so things like cracks and material defects that are hard (or nearly impossible) to find using Magnetic Flux Leakage tools are a lot more accessible to gas pipeline operators as they don’t need to do things like plan around liquid batching.
