Weekly notes

• Vibing a Non-Trivial Ghostty Feature: Mitchell describes how he uses an llm to help build a feature for ghostty. It took a few days and there were certainly points where he couldn’t get it to do what he wanted but it seems like there are ways to nudge a model towards a goal.
• How I’m using coding agents in September, 2025: Another write-up about how somebody is using coding agents to help implement a feature.
• Today is when the Amazon brain drain finally sent AWS down the spout: Interesting take on why aws might be seeing more large scale issues. Corey Quinn argues that the loss of senior engineers is leading to more outages.
• Summary of the Amazon DynamoDB Service Disruption in Northern Virginia (US-EAST-1) Region: Sounds like a dns issue with a dynamodb record. Lots of aws services depend on dynamodb for state storage it sounds like.
• A gold ceremony to remember: The creator of cURL is recognized for all his work on this critical tool that can be found everywhere …
• How I learn machine learning: Long post about how to learn something:
  • Read broadly
  • Then deeply
  • Read some of the academic literature
  • Deliberate practice (build something)
