Sometimes I get nostalgic and google something instead of asking AI. It’s like blowing into a Nintendo cartridge.

Big cleanup unlock yesterday. Gave claude two flipper endpoints (gates + telemetry) and told it to cleanup all my feature flags. I hand held it to be safe, but it didn't need it. 600 LOC gone and many features ready to delete from flipper cloud.

Another nice little conductor gamification. Each workspace is a city and they keep track of where you travel. Sometimes you get a rare one like I did today and feel special for no reason. Haha.

Just gave @bencurtis.com a preview of my APM. :D We talked through high level goals and all the scaling bits since he has loads of experience at honeybadger.
Current state: client gem works. Rails app works. Time to get this thing on Railway and try it out end to end to see how it feels.

If you're working in conductor on something small, you can just tell it to commit, cherry pick it to main and push. You don't have to do the whole pull request flow.

My new favorite workflow: go to Honeybadger, find an error that happens a lot. Export it as markdown. Make a new workspace in conductor, paste it in and let it rip.
Test, merge, and deploy.
Customers problems are just melting away now.

Man does my water taste great today. 🤣

What’s great about AI coding is how it reduces the time I used to require to even start on something.
Before if I didn’t have an hour, I wouldn’t even start a new thing. I would just do email or something non-coding.

Conducting Rails
I've been using @conductor_build heavily for weeks now and it's completely changed how I ship Ruby on Rails code when working with Claude models.
The multi-workspace, multi-process model feels unusual at first compared to a single editor flow, but once you handle the Rails-specific quirks, your ability to work

Mapped my Logitech MX Master 3 mouse thumb button to my right command key which is my Wispr Flow hot key (using karabiner elements). Game changer!

This was my first website. Made it in college in 2000. I've improved a bit in the past quarter century. If you have a more gorgeous first website, by all means share away.

TIL: default timeout for GitHub actions is 6 hrs. When you have a matrix of many Ruby/Rails versions, it eats through limits quite quickly if the GitHub action runner hangs for some unknown reason (support request submitted).

The unsexy truth is that distribution usually comes from doing one thing consistently for a long time rather than finding a clever hack.

If you're not piping your customer's support requests into claude with opus (or whatever your jam is) and responding with a fix, you are behind. This is the state of things right now. It's faster to fully fix their request now than to create an issue.

My lazy Sunday afternoon turned into a queue firefight. Our telemetry throughput doubled overnight thanks to a new bigger customer. 😅 I put in a new telemetry buffer and we're flying now but it took a bit to solidify it.

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. 🤣
