  • 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.





  • The ones I have have some speakers aimed at your ear to fill in that part, actually works really well. I can’t stand the ear buds you physically insert into your ears, the rubber tipped ones, these have been good to replace my on ears for activity. Plus you can hear what’s around you which is why my partner gifted me them.









  • 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.




  • 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.



  • As @renegadespork@lemmy.jelliefrontier.net said, infant mortality is a concern with spinning disks, if I recall (been out of reliability for a few years) things like bearings are super sensitive to handling and storage, vibrations and the like can totally cause microscopic damage causing premature failure, once they’re good though they’re good until they wear out. A lot of electronics follow that or the infant mortality curve, stuff dying out of the box sucks, but it’s not unexpected from a reliability POV.

    Shitty of Seagate not to honour the warranty, that’d turn me off as well. Mine is pettier, when I was building my nas/server I initially bought some WD reds, returned those and went for some Seagate ironwolf drives because the reds made this really irritating whine you could hear across the room, at the time we had a single room apartment so was no good.
