We used Codex to generate a million lines of code for a software product in 5 months with a team of 7 engineers, achieving an average throughput of 3.5 PRs per engineer per day. To maintain the codebase, we focused on designing environments, scaffolding, and feedback loops that enable agents to do reliable work, enforcing invariants and mechanical rules to keep the codebase legible and consistent.

There are many mysteries about deep learning and human intelligence, but we could describe the biggest anomaly this way: why are artificial neural nets smart in such stupid ways, and biological brains stupid but in smart ways? I propose a major change in deep learning scaling paradigms: the architectural differences between human brains and NNs (particularly LLMs) may be due to a ...

Moving beyond fork() + exec()

A recent Linux kernel proposal to add "spawn templates" to optimize the fork() and exec() pattern has been rejected, but it may point to a new process-creation primitive in the future. The discussion highlights the need for a better process-creation mechanism, with some suggesting a native implementation of posix_spawn() and others proposing alternative approaches using existing system calls.

PaceVer (an alternative to SemVer, for mobile apps)

Mobile apps don't ship the way libraries do. A library has one release channel and one question that matters: did the contract break? That's what Semantic Versioning answers, and it answers it well. An app shipped with React Native, Expo, or a similar framework has two release channels moving at two speeds. Some changes (a new native module, an SDK bump, a new permission) can only ...
