Just slayed the API endpoint performance for flipper cloud. Added memcached around the adapter used to deliver gate data. Should save me $2-3k/month.

Running prod without feature flags and other runtime controls is like driving without brakes. You’ll be fine… until you’re not. Yesterday I turned off some purging with a flag to shed load during a big db migration.

Control.set :telemetry_request_purge_job_wait, 1. Moved from deleting 500 rows every 2 seconds to every second. Easy to see on the uptick on @PlanetScale graphs. Controlling things at runtime is the way.

Anyone having weird @heroku issues right now? Our queue time was high for flipper but puma utilization was normal like things were stuck in heroku router or something?.

Deploying without feature flags is like coding without version control.

Continuously purge data from mysql via good job in a safe way. Controlled by feature flag and runtime controls for how many records to delete in a batch and how long to wait to run the job again (to control replication lag). Easy to turn off, slow down or speed up at runtime!

Flipper 1.3.5 is out. Mostly just some effort to make the active record and redis adapters Just Work™ more often than they were. Enjoy!.

1.3.4 was a quick follow up to 1.3.3 to make rack_protection key work again for the few people that were using it. 1.3.5 hopefully fixes some nagging issues. The first is around frozen strings in...

We shipped out tshirts to some OG fireside customers. We did it to say thanks. But caring is always good business. Today, I got an email from one of the customers who just moved another podcast to us. They said the tshirt reminded them they've been wanting to migrate it. 🔥🔥🔥.

Just ran into someone in a datadog shirt in the badlands. Of course I said hi. She said her brother works there. 😊.

So many goodies in rails of extras — particularly measure_queries. A lot of overlap with pghero.

Anthropic is a real one for this. Check out their console message if you are bored. I'm sure they copied someone else but this is a brilliant idea.

I want onboarding from Flipper OSS to Cloud to be the most seamless thing you'll experience. It's not right now. Gotta beef up my docs/examples/setup game. Quick easy step today was to add a flipper cloud example using redis as local store:.

Great post by Andy on how to deal with big IN clauses in Postgres. I didn’t even know about ANY.

A new thing we cooked up. He’s already on tshirts, stickers and starting to integrate him some into the app. Like our support link is Sid’s face and he gives you suggestions for what to post (powered by OpenAI and Claude).
