I agree, we try to think in terms in state machine. Just complaining that somehow this is not good enough, in practice we need to add random flags, and it is not clear how to separate the multitude of separate state machines all active at t

"No statechart will survive contact with real world applications". I mean, when you have external dependencies, multilayer protocols, multithreading, perf requirements, the state will becomes an ugly mess. One can only dream of a

But I see all the "QR codes" have a hexagonal symmetry? So basically you can use only one corner (1/6) to represent a node? Why do they keep the entire hexagon?

(also you receive the signal from all satellites at the same time, on the same freq, and some random reflections. and then you need to extract independent streams of bits for each satellite, each with its own nanosecond timestamp for receiv

And then you try to actually build a GPS network, and ask yourself: what kind of antennas should we use? what should be the freq? how much power? how will the receiver detect the precise nanosecond when it receives an incredible weak signal

The hw implementation of xor is simpler than sub, so it should consume slightly less energy. Wondering how much energy was saved in the whole world by using xor instead of sub.

You could use colors in the step-by-step simulation to show dependencies. Also show some tooltips/comments when things happen (that you described above). Ideally one should press next next next in the simulation, and understand what ha

Maybe it's just me, but the visualizations do not help me at all.

well, rhetorical trick or not, it is worth thinking about the fact that the dynamics of the thing are already outside anyone's control. I mean, everyone is racing and you cannot stop.

I found much more interesting the way the gps electronics work. What do you mean you need to know the exact moment you receive a message from a satellite with nanosecond precision? when the message itself is several seconds long.

A long time ago (pre-internet) I heard a normal person can learn to juggle in 1 day. It took me 2 days, but I learned to juggle 3 balls. But soon I realized what you said, the need for a consistent toss. Not sure of the reason, but I always

Even this OpenAI course is from 2020? Are there no useful recent updates on the subject, especially now with everyone working and using RL?

Looks average to me. Maybe I don't know how the good ones look? Can you give some examples?

This is actually insane. Do you mean 2-4 people in one department basically killed Intel? Roll to disbelief.

Thanks, but this seems to be optimized for the smallest number of gates, so it applies for simple microcontrollers and FPGA, and with limited precision. I was interested in actual state of the art used in modern CPUs and GPUs.

Does anyone knows the resources for the algos used in the HW implementations of math functions? I mean the algos inside the CPUs and GPUs. How they make a tradeoff between transistor number, power consumption, cycles, which algos allow this

Well, I mean just choosing better names, don't touch the actual code. and you can also add a basic human filtering step if you want. You cannot possible say that "v12" is better than "header.size". I would argue tha

Idea: pass the decompiled code through a "please rename variables according to their purpose" step using a coding agent. Not ideal, but arguably better than v03, v20. And almost zero effort at this time and age.

But it is very simple. There are some limits to what we can do, based on the laws of physics, but we are so far away from them. And the limiting factor is mostly the fact we are pretty stupid. AI should not have the same limits as us, so it

This looks like an IQ test, but for who?

Hi, thanks for the recommendations. I looked a little at the book, basically at the end we can compute some properties for small molecules sitting alone in space? What about arbitrary molecules, interacting? Or computing reaction rates? In

Trying to read the math behind quantum chemistry, it is never clear to me which parts are fundamental, which parts are tricks, which parts are needed just for close form expressions, which parts are computational approximations, and which a

Well, it is quite difficult indeed, but I am curious what will happen in the next 20 years, with China very interested in this, and some renewed interest in the west too. I am also not sure which is more unrealistic, cheap nuclear or fusion

If electricity is cheap enough, you can take CO2 from air and make fuel (not sure what is the threshold? 5-10 times cheaper then now?). then you can use that fuel where you need its energy density. I agree that it seems pretty dumb to ignor

Actually when one is old enough, the lethality around becomes much more visible.

Not sure how helpful it is, but: Words or concepts are represented as high-dim vectors. At high level, we could say each dimension is another concept like "dog"-ness or "complexity" or "color"-ness. The "a

Ok, what would be a vision of humanity you would agree with?
