  • I have the opposite reaction when I see these memes. To me it’s a reminder of how inclusive some of my favorite nerdy communities are, on top of being a fun little in-joke like any meme should be. And I’m an old beardy middle aged dad too for whatever that’s worth.

    However, that doesn’t mean the image itself is innocent or appropriate for most audiences. I’m not going to be asking the family’s opinion on this one, lol. But I don’t see it as a manga fetish thing at all. More empowerment than exploitation for the owners of the legs shown.




  • Totally, and I think that’s why they thought it was worth a press release. In the article they go right to how they’re setting a new power density record with this design.

    Electric motors are just really power dense. The article says they managed a short term peak of 1,000 hp with that little flat 12.7kg motor and the continuous output could still be half that.

    Just the cooling must be crazy.

    Out of curiosity I looked up something comparable. It looks like high-performance integrated drive units that have other stuff like the single-speed gearbox, differential, and inverter are still only in the dozens of kg.


  • The voltage/hp comparison there doesn’t really fit.

    Power is in watts or horsepower. You multiply the torque with the RPM and a scaling factor to get power.

    A higher voltage system could probably be expected to produce more torque and power from the same size motor, but a lot depends on the design of the motor.

    Then to answer “how much torque though,” I haven’t looked into it but electric motors have a very nice torque curve across the RPM range. If a motor made all that power with low torque, then it must spin at super high RPM and need to be geared down.





  • Thanks for posting this, because I started getting bummed thinking about how much of a great resource the full reddit history would be to just have online, were that whole thing not ruined gut bad reasons by bad people.

    But then you reminded me about the good people.

    I found the helpers, Mr Rogers!


  • Ok bear with me here but we’re on Lemmy so I think I get in trouble if I don’t ask this…

    Have ya tried Linux on the old machines? If not, you can make a bootable USB of Linux Mint and play around with it without changing anything on your system. The UI is laid out like Windows.

    Nothing makes an old machine sing like installing Linux!


  • When I switched over my home desktop to Mint, it was a very short time before I looked at Windows and said “I’m too old for this shit.” I mean, the reason I am a Mint fan in the first place is that I am a FOSS loving nerd but with a family and pets and hobbies and a career and a middle aged energy level. The decades I’ve spent fixing Windows based PCs is enough for a lifetime, thx.

    I say consolidate old files you want to keep. Shuffle them between drives as necessary to be able to format everything. Go all ext4 on the drives you already have. (once you’re ready)

    This is the way.


  • I think these days the PC value argument is a lot more about longevity and versatility than price.

    Like in my case, I want to have an old fashioned LAN gaming setup in my house. I’ve already managed to find four PCs stored away, and they are all going to work great. Three are already set up and have linux installed and everything. So they cost a decent amount in their day, but now they’re kind of just free extras.



  • That’s right about observation events. They are often called interactions instead.

    But the wave-particle duality applies to literally everything at the quantum level, per the standard model and quantum field theory anyway. And that’s a model with an incredible track record.

    Looking at a particle as a wave is usually in the context of that particle by itself moving in a straight line through a vacuum. There isn’t really vibration and temperature; there aren’t even atoms! You just have the particle’s energy in eV.

    Whether we can subjectively compare the packets of energy in quantum fields with the waves of energy through matter, I have no idea. The math is solid though.



  • I agree with everything you’re saying.

    And unfortunately as a life-long resident of white suburban america, I know how comfortable life still is for so many people, and how the culture of “ignore that problem and we’ll be fine” continues to pay off for people with a little privilege in their life.
