The conference is over now. I likely wouldn't have come for just a bitcoin thing, but I am very interested in redecentralizing the web, so it's attachment to the nostr day pulled me in.
Everyone I met was friendly and interesting and seems much more interested in making a better money system than in making money for themselves.
Our government and bank money systems are dysfunctional in all kinds of ways which are often less visible than they should be too people using them, especially to those in Europe and America who benefit from the way those systems exploit the global south.
I'm not convinced that fixing that would end wars and fix broken government as some seem to think, but I am sure our money is the source of many problems.
There are many bright, well meaning, and intelligent people building to improve bitcoin in fascinating ways with the hope of having a parallel system to transition to. With lots of work still to be done.
Can it work?
I'm sure I don't know, and I'm sure even if it's a better system it'll come with it's own unfairness and cruelty. Money will continue to be a source of suck and worry.
I'm told that the bigger conferences are often full of shitcoin scammers and suit wearing banksters who are in fact all in it too get rich and rip people off, but I found none of that here.
Here there is a real community of people trying to make the world a better place and improve the lives of their neighbours and governance of their countries.
And in the end building community is the most radical and effective way to change the world regardless of the problems of it's money system.
I had a great time. Thanks to those organising it.

Abstract: Holographic displays offer significant potential for augmented and virtual reality applications by reconstructing wavefronts that enable continuous depth cues and natural parallax without vergence-accommodation conflict. However, despite advances in pixel-level image quality, current systems struggle to achieve perceptually accurate color reproduction--an essential component of visual realism. These challenges arise from complex system-level distortions caused by coherent laser illumination, spatial light modulator imperfections, chromatic aberrations, and camera-induced color biases. In this work, we propose a perceptually-aware color management framework for holographic displays that jointly addresses input-output color inconsistencies through color space transformation, adaptive illumination control, and neural network-based perceptual modeling of the camera's color response. We validate the effectiveness of our approach through numerical simulations, optical experiments, and a controlled user study. The results demonstrate substantial improvements in perceptual color fidelity, laying the groundwork for perceptually driven holographic rendering in future systems.
