Big GPUs don’t need big PCs
Ever since I got AMD, Intel, and Nvidia graphics cards to run on a Raspberry Pi, I had a nagging question: What’s the point? The Raspberry Pi only has 1 lane of PCIe Gen 3 bandwidth available for a connection to an eGPU. That’s not much. Especially considering a modern desktop has at least one […]
OpenSCAD Is Kinda Neat
Designing a simple battery holder in OpenSCAD. Earlier this year I designed a very basic box/organizer for AA and AAA batteries in Autodesk Fusion, making it parameterized so that by changing a few variables one could adjust the battery type/size, rows/columns, etc. This worked well, and after uploading it to Printables earlier today I realized […]
Pure Silicon Demo Coding: No CPU, No Memory, Just 4k Gates
Dec 19, 2025 In addition to the VGA donut, I submitted two other entries in the Tiny Tapeout 8 demo competition, where you submit a “tiny” ASIC design (room for about 4000 logic gates) that outputs 2-bit RGB to a VGA port and 1-bit audio to a speaker. One was a an old school C64/Amiga […]
Over 40% of deceased drivers in vehicle crashes test positive for THC: Study
CHICAGO — New study findings show that over 40% of drivers who died in motor vehicle collisions tested positive for active delta-9-tetrahydrocannabinol (THC) in their system, with average blood levels far exceeding those considered to cause impairment. The research highlights a significant and persistent public health risk that is unchanged by the legalization of recreational […]
Go ahead, self-host Postgres
Self-hosting a database sounds terrifying. That narrative has certainly been pushed over the last 10 years by the big cloud providers: Hosting your own database is dangerous How are you going to get all the 9s of reliability doing it yourself? You’ll have access to dedicated database engineers that you couldn’t (or wouldn’t want to) […]

Approaching 50 Years of String Theory
Brian Greene has a new video out today, of himself talking to Edward Witten, mainly about string theory. Pretty much the usual decades-old hype, with nothing even slightly different than what a similar conversation would have consisted of 20 years ago. Of historical and psychological interest, Witten explains that when the anthropic landscape nonsense arrived, […]
Proving Bounds for the Randomized MaxCut Approximation Algorithm in Lean4
../randomized-maxcut Published on: 2025-12-19 For a given graph G = (V, E), a cut C is a set of edges such that there is a partition V = (A, B) where all edges e ∈ C have one vertex in A and the other in B. MaxCut is a very famous combinatorial optimization problem wherein […]
Raycaster (YC F24) Is Hiring a Research Engineer (NYC, In-Person)
Raycaster (raycaster.ai) (YC F24) builds a document IDE for high-stakes, regulated work in life sciences (CMC / quality / regulatory). The product turns messy, versioned documents (PDFs, Word redlines, tables) into a structured workspace where agents can search, cite, reconcile changes, and help draft. We’re hiring a Research Engineer who can both (1) ship production […]
