@UT_Dallas Will the library have power this week?

Our facilities team continues to work with Oncor on fixing the power outage that has affected many buildings on the UT Dallas campus. Currently, a timeline for power restoration has not been established. (1/2)

@InsiderWire Damn that was fast

#BREAKING: Active shooter neutralized at Old Dominion University in Norfolk, VA.

@bravo_abad @MartinShkreli if photonic matmul were close to viable at scale, why would Nvidia, Google TPU teams, and every well-funded AI lab not already be pursuing it aggressively?

Light does the math: inverse-designed nanophotonic chips that classify images at the speed of photons Electronic hardware has a fundamental bottleneck. Every time a neural network runs inference, weights must be fetched from memory, multiplied by activations, and written back—millions of times. At scale, this memory-bandwidth wall consumes enormous energy. One radical alternative: encode the weights directly into the physical structure of a chip, so computation happens as light propagates through matter. No memory transfers. Just Maxwell's equations doing linear algebra in femtoseconds. The challenge is that designing such a structure is anything but straightforward. You need a nanoscale material geometry that, when illuminated with encoded optical inputs, routes light toward the correct output port for each class. The design space is astronomically large, and human intuition fails completely. This is where inverse design becomes essential. Joel Sved and coauthors demonstrate inverse-designed photonic neural network (PNN) accelerators on a silicon-on-insulator platform, classifying images on-chip within footprints of just 20 × 20 µm² and 30 × 20 µm². Their method exploits a key mathematical fact: because Maxwell's equations are linear, the optical field for any input is a superposition of fields from each input port independently. Instead of one simulation per training sample, they need only N + C simulations per epoch—where N is input ports and C is output classes. For MNIST, that is 20 simulations per epoch regardless of dataset size, with epoch runtime increasing just 6.7% when going from 10% to 100% of training data. Gradients are computed via the adjoint variable method, and B-spline contour approximation enforces an 80 nm minimum feature size compatible with electron beam lithography. The result: ~400 million trainable parameters per mm². Experimentally, the devices achieve 89% accuracy on MNIST and 90% on MedNIST—a six-class medical imaging dataset covering chest X-rays, CT scans, and MRI. They also prove robust to input phase noise up to 1.18 radians, because the encoding scheme is amplitude-dominated. The light does not simulate computation. It performs it.

@Geiger_Capital Brings back hitler

Claude captured Maduro OpenAI killed Khamenei I can’t wait to see what xAI does next

@AutismCapital Bro XAI is shit, grok isn’t even close to Claude and ChatGPT

🚨NEW: Sam Altman says that OpenAI is currently negotiating a deal with the Pentagon after Anthropic's falling out with the Trump admin. Where does this leave xAI?

@elder_plinius Thanks 😊
