    You say it’s the goal of the proletariat to protect the revolution, but why would they? Each proletariat would benefit from the revolution’s failure- they could live better lives as the bourgeois. You talk about the proletariat like they are some monolithic entity, with a single mind and goal. You talk big about helping the individual, but cannot see beyond their class. The proletariat is a person, with needs, desires and opinions. What father would hold the abstract ideals of the “revolution” over the life of his sick daughter? Any father I know would do anything for the safety of his children, even hoard life-saving medicine from others.






  • I only vaguely really know what’s going on. I did some more research after commenting, and I think I understand a little bit more. The TI bubble memory has two separate layers. On of them, the ‘magnetic epitaxial film’, basically has a lot of magnetic molecules arranged to point in the same direction. The second layer has circles made of some nickel-iron alloy. What I think is happening is that the actual magnetic bubbles are held on the film, and the iron circles act as tracks the bubbles are pulled along. I don’t think electrons in the bubble are actually moving, but I think the electron spin is. That would explain why the loops are capable of moving the bubbles faster than electrons.


  • Just from a quick Google search, it looks like it’s similar to tape memory, except the data moves along the tape, instead of the tape moving over the reading head. According to this diagram by TI, it looks like the bubbles are on some iron wafer and forcibly moved around by two coils. Then, on a second substrate there are some type of read & write head.

    So here’s how I would go about this: first, I’d wrap some small metal plates in insulated magnet wire, place two permanent magnets on the top and bottom (sandwich style) and stick a read head on the edge of the plate. Then you push AC current through the two coils offset by 90 degrees. This should push the bubble in a circle, and that can be read by the tape head.

    Keep in mind though, this is a complete guess based on a simplified diagram from the 70s. I don’t actually know if this is how they work.








  • I hate being lumped in with all the zoomers in gen z. To me, gen Z is really two generations, gen Z is 1997-2006 and zoomers are 2006-2015. There’s just a huge cultural gap, at least in my experience. I’ll talk about how all my school computers used windows XP, and zoomers will just stare at me like I’m ancient or something.
