Building a GPU compiler from scratch, from PyTorch to CUDA (10 minute read)
This deep dive uses the Emmy compiler framework to follow PyTorch operations down to CUDA one lowering stage at a time: Tensor IR, Loop IR, Tile IR, Kernel IR, and finally emitted code. It uses RMSNorm and matrix multiplication as worked examples. It also covers operator fusion, schedule selection, and online attention rewrites, so readers can see what Triton-style stacks do under the hood.
Physical Intelligence opens a beta API to fine-tune and host π robot models (3 minute read)
Physical Intelligence opened a beta API for its π robotics foundation models: upload demonstrations, fine-tune on Pi-managed compute, and run the result on your own robot through a hosted inference gateway. Early partners spanned hardware from Actor's autonomous wheel loader, running a commercial deployment with no operator onboard, to Almond's dual-arm Axol, which learned to deburr its own spacers in four days. Since most ran cloud-hosted inference, network connectivity was a pain point for some.
What a 1GW AI data center costs: about $30B, and $17B of it is chips (10 minute read)
An Abilene-scale build requires roughly $17B for chips and servers, $3B for power, and only $2.4B for construction. Transformers, generators, and cooling equipment face long lead times and rising prices.
Apple Home Collection brings LG and Schneider cameras, a lock, and thermostats to Apple Home (3 minute read)
Apple's Home Collection, built with LG and Schneider Electric, covers cameras, thermostats, sensors, a doorbell, and a deadbolt. LG's lock uses Ultra Wideband to unlock as you approach and works locally over Matter and Aliro, while its indoor cam physically tilts away when someone's home. Every device supports Thread, and cameras keep recording to built-in storage if Wi-Fi drops. Prices run $199.95 to $399.95, with availability starting in December.
