Geraldo Nascimento knows the secrets of unlocking cold fusion, activating telomerase without causing cancer, manipulating gravity and opening traversable wormholes.

He likes to keep quiet about that secret stuff though, preferring to DJ, produce music and hack the Linux kernel.

And you'd need to be sure that the work being done wasn't some real-world scam... I see the point of how difficult it would be - I'm just saying that's tremendous value.

Thank you @gruez, @shagie and @px43 for your invaluable insight.

The only way I can foresee a cryptocoin actually holding value is if spending the coin meant spending processing cycles and RAM doing things like this:

But in more general sense, less like https://boinc.berkeley.edu/ and more like AWS...

It's the only way to have value, actually holding computing power in a distributed network.

You might want to take a look at ProjectM's codebase too: https://github.com/projectM-visualizer/projectm

> What resources does the HN community recommend for someone diving into creative coding, such as animated graphics, Shadertoy, audio, and live coding music?

I recommend you give Panda3D a try, particularly the C++ API. Here's an example of my musical work visualized in Panda3D: https://www.youtube.com/watch?v=bHW7B2TKk6Q

> Do you have any tips on achieving demoscene type graphics and music?

I think you should reconsider your line of thought. demoscene type graphics and music are usually coded with assembly for speed optimization and there are hard limits on the size of the binary, usually.

Is that really what you are pursuing?

geraldog··on Sit.
Cool, but there's an error there. "Just sit" is not a Zen koan, although it is a meditative technique used in Zen-Buddhism, particularly the Japanese Soto school of Zen. See https://en.wikipedia.org/wiki/Shikantaza
geraldog··on Using the Radxa Rock Pi N10 NPU on Mainline Linux
Author here. Got the official repository wrong for NPU firmware. Fixed it now, belongs to user "airockchip" on GitHub and latest commits have been authored by Randall Zhuo from Rockchip, so it seems to be official at least.

Well the simplest example I can give you is overclocking your CPU or GPU. If you do that past a certain limit, it would be damaging to the hardware don't you agree?

The correct implementation of the power-up script for Rock Pi N10 NPU should be as a kernel module, this way we don't have to enable any dangerous #defines in clk.c

Thanks, it means what it means, it asserts a #define on clk.c whereby root will be able to do very stupid things with clocks...

So you ditched the old v4.4 Rockchip vendor kernel in favor of Mainline Linux and now half of your SBC doesn't work! Well, trouble no more, at least I'll help you get a working NPU for accelerated AI inference.
