With these accounts, we could then access internal OpenAI repositories, and potentially many other connectors. To prove we had in fact gained the access we believed without allowing ourselves to learn any sensitive information, we used the employee’s Codex to open a PR #1186742 in OpenAI’s internal monorepo openai/openai.

If we do not have a common understanding of what “now” is, a lot of things we take for granted will stop working. This summer, Australia realized this the hard way. Let me take this opportunity to give an example of why time matters to a modern society, what happened in this particular case, and what our key takeaways are.

🚀 Read this trending post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: Retry storms historically impact business operations and brand trust. While retry configuration tuning and retry budgets provide meaningful mitigation at the service level, they’re manually configured and lack visibility into cross-service amplification caused by deep dependency chains and fan-out patterns. As a result, it can be difficult to shield infrastructure against the domino effect triggered by a single service outage deeper in the stack. A key reason is that retry behavior today isn’t context-aware. While we can control how many retries occur, we can’t precisely control…
