There's a lot of fear-mongering about AI coding agents these days. But when you follow the right process, they're perfectly safe. Check out this screenshot of a proposed change that I'm definitely not merging 😁

Is Manus AI the most polite AI agent??

It's so polite I feel mean asking it to do more!

Our Kids AI Genius waitlist is buzzing!

Despite only sharing it in a few replies and on IndieHackers we've had a constant stream of sign ups.

I was curious about where all this traffic is coming from, so I've got PostHog analytics on the case and we are just waiting for results.

The "is Rails dead?" debate has finally met its demise.

In just ONE day, I crafted three apps—web, iOS, and Android—using Rails 8 combined with Hotwire Native. No exaggeration.

Can't get your kid to do math? Tried Fortnite math with my 8-year-old.

"If you eliminate 4 players in 3 matches, how many kills total?"

He went from hating multiplication to begging for more problems.

"You have 243 ammo and pick up 180 more. How much ammo do you have?"

Do you use the bun package manager and dependabot?

If so, you might want to try the experimental support for bun in dependabot.

Add `enable-beta-ecosystems: true` to your `dependabot.yml` and add the `npm` package ecosystem. You can see an example below.

Let me know if you try this!

My son hated multiplication until I turned it into a Fortnite game. 🎮

"If you eliminate 4 players in each of your 3 matches, how many total eliminations do you have?"

Noah Gibbs (codefolio, YJIT team, Rebuilding Rails author) has passed away.

His big dream in life was to help build the Ruby community up. He wanted to be like the folks who worked to create the railroads during the industrial revolution.
