Hard to take Claude Code’s ‘auto’ mode very seriously when they just inadvertently leaked the Claude Code source code.

Same. When it implements the next step as directed, I smile and nod. When it deviates (or bloviates), I sigh in the same way that I sigh when I realize my friend has had one too many and I'm the only one capable of getting him home.

I'm only one datapoint, but I'm experiencing far less flow state and less job satisfaction. Waiting kills flow, and much of the agentic development experience is a waiting -> verifying loop.

Great post, though I'm conufsed about this bit: "We replaced wallaby with phoenix_test_playwright for browser testing" All of our wallaby tests already run concurrently. Are there additional perf gains to be made by leveraging playwright?

The Official #ElixirLang LSP is now easily leveraged in VSCode via the official VSCode extension. I've been using it for about a week, and it's at feature parity with what I need. kudos to @mitchellhanberg.com @dorgan.bsky.social Łukasz Samson and others! marketplace.visualstudio.com/items?itemNa...

I've started sprinkling dictation into my (mac) workflow, and one place it's become really valuable is when having to submit 2FA verification codes sent to my phone. Reading them out is way nicer than writing them out, though I only recommend you do so when in private. Try it out!

When you upgrade to 1.19, don't forget to leverage MIX_OS_DEPS_COMPILE_PARTITION_COUNT. And not just locally, but in CI and production pipelines, though the latter two *may* take some tuning due to increased memory usage. Happy upgrading! #ElixirLang

We didn't see large gains in perf in our test suite, but the less dependencies the better, and it's nice to not have the floki-specific selectors in the codebase anymore.

If ever there was a great busy-work task for Claude Code, it's converting all Floki parsing in a repo to the LazyHTML equivalent as a follow-up to the LiveView 1.1 upgrade #ElixirLang
