<p>I had a long ELI16 session with Claude about it, and the way I understand it is that they<p>- use Ising machines to describe a certain problem into clauses, storing system state (e.g. spin of something) in variables<p>- then use a neural network layer where each neuron determines the value of one clause<p>- then for each state item, use the neuron output to determine if flipping that state would improve the overall system score<p>- and then use FN-like "noise" to determine whether to flip or no<p>If the energy landscape of the problem is pretty local, this is guaranteed to find a good solution to the system, using way less compute than brute-forcing it.</p>

<p>I'm really curious about the reproducibility. The color is decided by the bandgap and the bandgap is tunable by voltage, but how temperature dependent is it, and how much does production variability impact it?<p>I image these displays could have color sensors attached to self-calibrate.<p>Or the variability is low and all you need is very precise voltages.<p>I think the first versions will be RGB displays with fixed colors, just no longer needing mass transfer. You could use tens of subpixels per pixel, reducing all worries about color resolution.<p>Make these into e.g. 1x1cm mini displays and mass transfer those into any desired display size.</p>

<p>I got dramatical improvement in my myopia over a few months time when I switched to a Paleo-ish diet, drastically cutting sugar and supplementing with vitamins including luteine.<p>I no longer needed my glasses to drive or go to the movies. Granted it was only -1 but still.<p>Now a decade on, my diet isn't so clean any more, far away details are somewhat blurry but still better than they used to be. The biggest impact is the amount of sleep I had the night before.</p>

<p>> CONCLUSION<p>> We introduced BtrBlocks, an open columnar compression format
 for data lakes. By analyzing a collection of real-world datasets, we
 selected a pool of fast encoding schemes for this use case. Additionally, we introduced Pseudodecimal Encoding, a novel compression scheme for floating-point numbers. Using our sample-based
 compression scheme selection algorithm and our generic framework for cascading compression, we showed that, compared to
 existing data lake formats, BtrBlocks achieves a high compression factor, competitive compression speed and superior decompression performance. BtrBlocks is open source and available at
