To me "learning" means understanding, not memorization on flashcards. Knowing stuff is part of it, but for me, the knowing comes from the understanding.

I would describe this as a non-injective function. Unambiguous in one direction, but ambiguous in the other. It seems to be very common in lecturers who (1) have forgotten what it was like to learn it (2) aren't precise enough to ensure clarity as a matter of rigour.

Criticism aside, learning something is infinitely better than learning nothing. And finding a way to make it enjoyable and satisfying is a worthwhile end in itself.

In A Fire Upon the Deep, the Skroderiders' cargo was a one-time pad.

Sounds like depletion of something, perhaps in the energy metabolism pathway, such as thyroxine.

"SSD as RAM" is a good way to reason about it.

It means you have a lot more RAM, e.g. thus, PS5 has 825GB of RAM. RAM in the TB, soon.

Would a couple of orders of magnitude make a difference? If software is designed with terabytes of RAM in mind?

Ratchet & Clank is the only demo with new gameplay based on the SSD.

But it's overused, giving each game world less weight. The technological imperative, preoccupied with whether they could, etc. In contrast, artificial constraints add depth to gameplay, e.g. limited movement speed/duration ("sprint").

All that said, keeping processors fed with data is a central problem of CS. The innovations here are not just the SSD itself, but elimination of bottlenecks in the architecture (e.g. direct placement in GPU RAM).

Typically, storage is 1000x slower than RAM. On PS5, it's 50x. That has got to be a revolution in algorithmic space-time tradeoffs... which has got to be reflected in gameplay, somehow, somewhen.

For covid19, some countries didn't take it seriously until they saw what happened in Italy.

This could happen for global climate change, if we have dozens of Earths.

> early birds looked very much like infantile or even embryonic raptors

Sounds like neoteny, the retention of juvenile characteristics in adulthood. See: domesticated foxes, dogs (esp toy breeds), people. Seems like a particularly easy evolutionary path, perhaps take a step back, then forward.

From a VC's point of view, for early startups, only pre-chasm matters. If many don't cross, well, it's a numbers game.
