The most annoying difference between #Codex and #Claude for me personally is the lack of plan mode. This one small CC feature prevented so many stupid overengineered #AI slop for me 😂
In general, I like the concept #OpenAI #Codex introduced: task -> variant -> feedback loop -> pull request. Feels almost like talking to a human through PR review, but there are quite a few things that I don't like:
- Lack of Docker containers inside the Codex environment.
- #Codex UI always shows the whole thing, without an option to see the diff of the latest changes in the branch.
- Integration with GitHub pull requests is apparently not as great as it could be...

What a nice coincidence! #Claude Code 2.0 was released just in time for this experiment. 😎

So far: #Sonnet 4.5 feels good. Some random API errors, I have never seen before, make working with CC feel like working with #Codex 😂

The model is definitely less agreeable now, which is also nice.

Trying to work with #AI as if it's a human engineer in a micro project. Quite an interesting challenge: on one hand, the amount of knowledge poured into LLM is stunning, but there's so many issues with “local” context…

Back to maintenance operations: #GitOps isn’t just for CI/CD or deployments—it’s also a robust framework for reliable maintenance tasks, especially one-off, long-running operations.

Boring reminder: If an alert isn’t actionable, it shouldn’t exist. Alerts are for action, not noise.

The beauty of microservices and containerization: Language barriers have faded. Develop in Python, deploy in Go, connect via gRPC or REST - mix and match as needed. No more rewriting everything in Java just because the stack started that way!

Captain Obvious strikes again: when setting up blackbox_exporter to monitor your endpoints, host it on a separate server/cloud. Not on the same cluster you're going to monitor. A downed blackbox_exporter doesn’t export much 😄

#Terraform lets you keep modules in the same repo as your code, which is great for getting started. But as your deployment logic grows, consider moving modules to a separate repo.
This brings major benefits: better version control and easier QA/testing for module changes.

When planning a new service that handles customer data, and if maintenance procedures are required, always ask: how can this operation be safeguarded? How will we observe progress? How will we handle failures?

Design maintenance operations to be safe by default.
