WHAT IS QUANTUM ADVANTAGE ACTUALLY WORTH?

Nearly all roadmaps point to a utility-scale quantum computer being developed around 2030. Despite this, there is little confidence or clarity on how these machines will actually be useful. The consensus is now that they'll first be used for breaking cryptography. The second most concrete answer is to use them to generate simulation data for AI labs' science models. This post looks at how else quantum computing could be applied and where all the revenue will come from.

SCALING GIT AT OPENAI

OpenAI's monorepo's size and demands increased at a staggering pace over the last year, necessitating a revamp of the AI lab's source control system. Its technical staff built Pando, a new backend for Git repositories optimized for concurrent pushes to many branches and to maximize read throughput. The team implemented the backend without interrupting any engineering work or changing how the team uses Git. Pando cut median push latency in production by nearly 5x, and it now delivers nearly a petabyte of Git data per day.
