- How I Dropped Our Production Database and Now Pay 10% More for AWS:
Lots of reliance on AI here and possibly not much awareness of how the
underlying infrastructure works or how to create safety in a process with lots
of automation. A lot of hard-won experience unlocked here. I like that he
owned his mistake.
- Ghostty Is Leaving GitHub:
Github has apparently not been very reliable lately. I use bitbucket more than
github these and haven’t really noticed reliability decline over the years but
some people have and are sad.
- Harness engineering for coding agent users:
Talks about agent harnesses and the closed loop one tries to setup where a
change is made, tested, and learnings collected which are fed back into the
next change. How do we evaluate the health of the harness itself which is an
important aspect of development context. If it falls out of sync with the goal
because of bad signals or memory that isn’t helpful anymore it’s no longer a
good tool for the task at hand and should be rest. How do you know you’ve
landed in that state?
- April 2026 Outage Post-Mortem:
Postmortem for a bluesky outage in April. Sounds like they had an api endpoint
that started to get post batch sizes much larger than they were expecting
exhausting ports available to make new connections on. We learned about delays
after a socket is closed by the application where the o/s holds onto the
socket for up to 2m waiting for any lingering packets that may yet come due to
network blips.
