Harness engineering: Leveraging Codex in an agent-first world

https://images.ctfassets.net/kftzwdyauwt9/1Gu58eNlqDEuITmbqJDmq9/1e2e62f7e15fb16d2da0da5407240564/fig_1__codex_drives_the_app_.png?w=3840&q=90&fm=webp
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.

Introducing Boron Buckyballs: Theory that B80 cages can’t be made is disproved

https://s7d1.scene7.com/is/content/CENODS/485651-bbb?ext=.gif
Chemists have observed a boron buckminsterfullerene for the first time, providing evidence for an 80-atom cage structure. This discovery challenges density functional theory and may lead to new materials such as semiconductors or superconductors.

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.
