Here's an intuitive explanation for L1: Imagine you have two planetary bodies fixed in space. A free mass is attracted to both, but it's possible to find an unstable equilibrium somewhere between them. Put the mass here, and it&#x

> I thought it’s a given that since both CNNs and CAs are Turing complete, you can use one to simulate the other. They are both Turing complete, yes, but the similarities are deeper. Recurrent CNNs are a very natural way to describe CAs

Yes! This was very much inspired by Shannon and Thorp. I love that story.

Yeah, it's not anon: the game was retired from machines and I left the ROM out. Wouldn't recommend to do for other than fun (and tbh hourly wage would be very small), but was a fun side-project!

Yep.

It's not anon. The game was retired from machines and I left the ROM out. Hourly rate probably wouldn't be very high if you did try to actually make money. Fun challenge though!

The game was recently retired from machines and I left the game ROM out. Fun as a challenge though!

Nah this was really just a fun side-project, just posting as proof-of-hack. Also this specific game was retired from machines. Fun as a challenge, though!

Many hours of searching through internet archives of dead forums. I don't think you can find it any more.

I got asked to be on a University Challenge team after someone saw me playing... but completely flopped when they asked independent questions at trials. This kind of unlinked data leaks very fast, too: at my peak I had to top up with Anki f

Yes, and the decryption code had been bundled into the binary! I tried inspecting it as you say but it seemed easier to just solve it by hand.

I tried this initially and put all 30K questions in Anki. I learnt about 97% of them, but it still wasn't good enough to win

It's legally not a gambling machine -- it's a 'game of skill', which means you can put it in a pub without a license. Gambling laws don't apply.

These are typically found in university towns in the UK.

Yes! This is because of UK legislature. You don't need a gambling permit if the game is skill-based.

Heard on grape vine that IBM claim to have pulled first silicon for a memristor RPU (design like below) just over a month ago. https://www.nature.com/articles/s41586-018-0180-5

Thanks. Can you recommend any books on these topics?

What technology needs to be developed to get the data on synapses and neurotransmitters? A high-resolution Raman imaging microscope? And is a dead brain sufficient, or would you need a real-time noninvasive scan of a living one?

The interesting meta-point here is the chicken-egg problem between cheap robotic hardware and large-scale data collection. We don't have general-purpose robotics because there aren't enough robots being built for them to become ch

Yep, it all ends up as heat. Energy is conserved, so if it didn't end up as heat, it would have to go somewhere, and there isn't really anywhere else it could go. Related topic: reversible computing. You might wonder if a computat

Depends on UWB bandwidth+power, how good your processing is + how many antennas you have... You could also get way better with a fleet of trucks spaced over a large area, or a city-sized swarm of drones, or satellites...

Yeah this is why you'd use UWB -- the capacity is insane. Also the raw information theory calculation makes sense only if you have zero prior information about the sample you're reconstructing. But 'people in buildings'
