Language Models Pack Billions of Concepts into 12k Dimensions

In a recent 3Blue1Brown video series on transformer models, Grant Sanderson posed a fascinating question: How can a relatively modest embedding space of 12,288 dimensions (GPT-3) accommodate millions of distinct real-world concepts? The answer lies at the intersection of high-dimensional geometry and a remarkable mathematical result known as the Johnson-Lindenstrauss lemma.

iPhone 17 might seem like the most boring model this year, but it’s a silent winner

Apple wrapped it its ‘Awe dropping’ launch event for the new iPhone models, Apple Watches, and AirPods Pro 3 yesterday. While the new iPhone Air and iPhone 17 Pro are much more interesting – I think the base model iPhone 17 will actually end up being a sleeper hit.

AMD Turin PSP binaries analysis from open-source firmware perspective

Introduction In the previous post, we showed coreboot running on Gigabyte MZ33-AR1 with Turin CPU, the current, newest family of AMD server processors. However, we faced various obstacles and problems. Despite AMD publishing a set of blobs required for the Turin system initialization, they turned out to be not enough to release the CPU from reset by PSP. We were forced to do a workaround by injecting coreboot into the vendor firmware image and flashing it back. The whole process is far from ide

Lens blur field shown in step 2 is from the dual pixels of a Pixel 4a. Abstract Optical blur is an inherent property of any lens system and is challenging to model in modern cameras because of their complex optical elements. To tackle this challenge, we introduce a high‑dimensional neural representation of blur—the lens blur field—and a practical method for acquisition.

Does All Semiconductor Manufacturing Depend on Spruce Pine Quartz? (2024)

news.ycombinator.com Brian Potter 2025-09-24 20:12:46

Here’s an idea you see spreading across the internet every so often: that all semiconductor and solar PV manufacturing depends on extremely pure quartz from the town of Spruce Pine, North Carolina. This quartz is used to make the crucibles which hold the molten silicon as it gets turned into silicon ingots, which are then cut into wafers and made into chips. The quartz needs to be very pure to prevent impurities from seeping into the silicon, and Spruce Pine is where this very pure quartz comes
