    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’ve used the wired equivalent of the Logitech g502 for a while, and my partner has the wireless one, I liked them as well. I’ve used Logitech, steel series, Razer and Saitek mice over the years, started with a Logitech G7, and there’s a reason I went back to Logitech mice after using some of the others. Imo you can’t really go wrong with one of their midrange models with a decent sensor, won’t break the bank and found them fairly reliable.

    As a bit of an alternate, I know you prefer wireless, but I’ve been using a Ploopy Mouse for few months now. I don’t do online fps stuff anymore, but was great for FPSs (some boomer shooters mainly) and RPGs it’s solid, been playing a lot of Diablo 2 recently and it’s great. It runs qmk so it’s customisable however you want, sensor seems decent and the entire thing is open source, designed for user serviceability.







  • 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’ve had fruit flies before that must have come in on some produce, have to be on it to clear them, leave out any fruit/veg scraps and they come out (out being tossed in the trash/green bin too, anything open air). Drop of dish soap, water and vinegar in a high walled glass or jar is the way to do it, I used balsamic but malt or wine vinegar works too, just leave that out and it’ll do its job.

    My current place we jokingly call the spider house, have a bunch of house spiders around (cats love them) and a few orb-weavers, garden and wolf spiders outside, pretty much anything native isn’t a threat to humans or cats, they do a great job of taking out any pests, rarely see flies inside these days. Spiders and centipedes I’ll leave alone, they’re beneficial to have around.
