    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.





  • So, I like loose leaf when I can, but will totally use bags, I grew up with Tetley so that’ll always be the tea I’ll use for some basic iced tea. Yorkshire gold reminds me a lot of Red Rose, which is the other really common bag tea (and I swear is what my grandmother uses for her water intake). Recently, have some bags from Genuine Tea, it’s a Canadian brand and some of their blends are pretty good, there’s an elderberry hibiscus one that’s great to just toss a few bags in a pitcher and cold steep.

    Going to mention more types of teas rather than brands that I’ve liked in the past, there’s a lot of variety and tea (like quality coffee) can totally have a wide range of flavours depending on region, age, processing etc. By no means an expert, I just like trying things.

    I like Lapsang Souchong sometimes, can have a strong smoky flavour, don’t have any more but we had some first flush Darjeeling tea that was fantastic. I had some nice white tea as well, but you need to be careful, turns super unpleasant if you over steep it or have the water too hot, should be floral and lightly fruity, not pine needles.

    Otherwise, I personally like oolong and pu’erh tea the best. I tend to brew tea quick with an excess of leaves, but you’ll use the same tea leaves multiple times. Pu’erh can have some earthy subtle flavours, and apparently totally changes as it ages (it’s fermented if I recall).


  • 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)
