If I were Anthropic, I'd buy conductor.build and port it to other platforms. It's such a huge unlock on top of claude code. Dramatically better than TUI.
Conductor - Run a team of coding agents on your Mac
Create parallel Codex + Claude Code agents in isolated workspaces. See at a glance what they're working on, then review and merge their changes.

For those that are curious how I use conductor with rails. Just remember to default PORT to CONDUCTOR_PORT and be sure that action mailer/controller/etc all get that PORT.
Then symlink any git ignored files from your root to the workspace folder.

Biggest thing is default PORT to CONDUCTOR_PORT and derive everything from that. Be sure to symlink any git ignored files that you need from root to workspace. Stuff like that.

Found out yesterday that all 3 of our furnaces need to be replaced. Then got a flat tire en route to dinner last night.
But this morning I'm back in the saddle with claude and conductor and there's a smile on my face. The fun I have building with them heals all wounds. 🤣

Started using Claude max with opus in December and Conductor three days ago (bottom right bright boxes). Very easy to see December is brighter and the last three days are neon/radioactive. 😎

Every dev tool needs copy as markdown for AI feature somewhere in their app. Doesn't have to be a prompt, but it should make it easy to copy the info well formatted so you can paste to claude.
caboose, the local rails dev tool i'm working on for perf has a copy. honeybadger already does it.

Flipper Cloud now shows up to 90 days of telemetry data (up from 24 hours). Know exactly when a feature flag is safe to delete.

Telemetry Timeframes
Up until now we've only shown 24 hours of telemetry data even though we've been storing more history. 24 hours was great because that's usually enough to know if a flag is fully removed from the code and ready to be deleted. But sometimes you need a longer time frame,

Your job as a tech leader now is to get claude code max, default to opus, get your local dev env setup agent friendly, then do the same for everyone on your team. Learn how to be super human and then teach everyone else.

Day 1 with conductor was awesome. Got several projects working based on CONDUCTOR_PORT and created a lot of code I need to QA/merge.
Love the tight GitHub integration and the UI is gorgeous.

Just learned about ctrl + cmd + Q to lock your Mac screen but let your laptop keep churning. Great for claude working but locking your screen to use the restroom or whatever quick while staying secure.

I keep coming back to cursor for git because of the syntax highlighting and full context of file. Fork has barely syntax highlights anything. Github Desktop has more highlighting but less context of full file. The diff only means you miss some context and my brain struggles.

Had to swap to postgres from sqlite for my barn basketball reservation app on @railway. Bummer.
If you have a volume, railway doesn't like deploys. The previous deploy crashes when the new deploy mounts the volume. So every deploy means downtime and a notification about the crash.

If you want to hear what a difference a good mic/studio makes, listen to first few seconds of episode 8 (saas checkup) and then episode 9 (back in the studio, when we switched from my home mic to momentum podcast studio + mic).

Just shipped a new playlist embed for @fireside.fm customers. I think it turned out nice. New website themes and more coming soon! We're finally starting to push forward after a year of behind the scenes work.

I'm using cursor less and less. At this point, just for a diff and sometimes commit/push. Decided to try some stuff focused on just that. Claud recommended git-fork mac app. Pretty nice onboarding and experience with a couple setting tweaks. Anyone already using this?

Fun claude prompt: "Can you give me a summary of all the PRs merged this year". Make sure you have `gh` installed/auth'd. Then follow up with "compare this to the previous 5 years".
