    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)


  • If I recall the Verb-Noun idea is supposed to make it clear what is happening, take a look through stuff like the approved verbs for defining cmdlets. There’s aliases and stuff for sure for example I think ls is an aliases for Get-ChildItem in PowerShell.

    It’s supposed to make it so you don’t necessarily need to look things up, need to do something to an item? Well you can Copy, Remove, Rename, Move etc, and while yeah that’s a super basic example that you know the equivalent linux commands for, the concept is supposed to apply everywhere. Now, whether or not people follow the guidelines is probably another story.

    I don’t really hate shell scripting, feel like they all have their place, complex stuff though is nicer in straight PowerShell than bash IMO, but I’m fine using either.




  • I really liked what they did with type matching too, and that shines literally are a different type, had an absolute blast with the game, plays really well on the deck (though it absolutely eats battery life), sticker system was really cool too, just in general they really did a stellar job of interesting systems and the story was interesting too.

    Thinking about it now, I kinda almost want to call it a Pokémon/Golden Sun like? Golden sun had a really awesome system with Djinns where mixing different elements and changing if they were set would literally change that characters class, granted them totally different powers and stats, I’m operating on memory since it’s been a long time but it’s an amazing game, easily my favourite GBA title and I knew there was another game it was reminding me of.


  • 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.
