    Industrial cooling towers are usually evaporative in my experience, smaller ones are large fans moving air over a stack of slats that the return water is sprayed or piped over and the collects in well for recirculation, larger ones afaik (like what you’d see at power plants) operate the same idea. Top ups and water chemistry is all automated.

    Those systems have operation wide cooling loops that individual pieces of equipment tap into, some stuff uses it directly (see that with things like industrial furnaces) but smaller stuff or stuff that’s sensitive you’ll see heat exchangers and even then the server & PLC rooms were all air cooled, the air cons for them were all tied into the cooling water loops though.

    From a maintenance POV though, way easier to air cool, totally seen motor drive racks with failed cooling fans that have had really powerful external blowers rigged up to keep them going to the next maintenance window. Yeah, industrial POV but similar idea.



  • 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)


  • That’s super bizarre and sorry you’re having those issues. I have a 4070ti w/ an 11900k on arch (use debian on my laptop and printers, chose arch for more recent releases for drivers in particular) and guess I’ve been lucky, arch wiki won’t 100% help but might point you at other possible configs?

    Had solid luck with the nvidia-open drivers, and really other than setting a few flags for hdr in KDE (which I’m not sure it’s still needed), I do recall looking at DRM kernel mode settings (section 1.2), most of my grief though has been HDR related (and gamescope doesn’t play nice with some games, steam big picture also can render strange on higher resolutions)

    Getting washed out HDR on a 4070ti on 570.144 drivers for whatever reason, but gamescope w/ HDR seem to work perfectly with Proton 10 (Both the valve beta and now GE versions, it’d freeze when trying to enable HDR in the past), having HDR at all in games is a huge win so I’ll take it.

    Tried GoW Raganarok and Cyberpunk for reference


  • 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.










  • Was a kubuntu person for a long time, I haven’t really loved the default Ubuntu DE for a while, but that’s personal preferences. At the end of the day, use what you like.

    I personally like debian (swapped from Kubuntu over time) but keep mint on my thumb drive for family who needs something on older hardware, especially those used to windows it seems to be an easy jump. I love that there are so many options available to people with various levels of prepackaging and configurations.
