These metal page makers are great! Another thing in a similar vein are the midori index clips but a little more pricey. They also have a little notch in them, sometimes I will slot a small piece of coloured paper in there so I can visually categorize what the clip is marking.

I will also sometimes mark pages with differently shaped paper clips (also helps with category identification) if I don't care too much about adding bulk, usually in my notebooks.

I wasn't able to make it to the q&a. Did it manage to get recorded in a shareable way?

I think something like dynamicland or folk.computer has a chance to fill a more novel product niche. They have the potential to be a more physically social kind of computer experience. Unsure if they can outcompete the addiction capacity of smartphones though.

What makes you think that that space combat is significantly more likely to be defence dominant?

I'd also recommend going through both the essence of linear algebra and the essence of calculus if you're not familiar with those subjects as well.

Highly recommend to watch all the playlists with a pencil and paper and actually write out the equations while thinking about them to get a good grasp on the concepts.

I did the survey! Skipped some questions out of laziness though

Indeed! I was very close to writing a whole bit about TEEs, enclaves, and PUFs in my last comment, but I figured that it also boils down to "just don't give it permission" so I left it out. I actually think designing secure hardware is incredibly interesting and there will probably be an increase in demand for secure computing environments and data provenance in the near future.

This is an extremely hard problem. One way to demonstrate this is is to ask the less constrained question, how would you prevent an adversary from copying some arbitrary piece of data?

I think under a classical computing paradigm this is likely impossible. But is there a way we can make the data useless even if it is copied? This then becomes the realm of cryptography, and seems possible with fully homomorphic encryption and the like. This will boil down to "just don't give it the secret keys", which seems like a pretty solid subset of "just don't give it the permission".

Under a quantum computing paradigm this might be possible, but that would require waiting for QC hardware to become commonplace and I don't think anyone is waiting for that.
