I've also been reading through @palkan.bsky.social's & @evilmartians.com Layered Design for Rails and it's cool to see many similar ideas for where I'd like to see Rails go (and Associated Objects gets a mention).

There's lots of interesting ideas and patterns in there, so I highly recommend it!

Meet Andrey (@en.sitnik.es ), our frontend principal and the creator of PostCSS.

He was our first hire ever and has been a Martian for 15 years.

Andrey is based in Barcelona, is a loving father, and is always down to meet up with martians IRL.

We knew Martians were some of the best of their kind.

So we're building individual portfolios to show it and allow clients to:

- Get paired with the best person for their project
- Understand the background of the one joining their team

This process has made us feel incredibly proud of Martians.

Harjot Gill bootstrapped @coderabbitai.bsky.social to $1M ARR before raising a $16M Series A. That was followed by a $60M Series B, and now revenue is doubling every few months.

In the episode of Dev Propulsion Labs, Harjot shares why the open source version plays a huge role in that growth.

We get our industry news from @anycable.io's Broadcast. Issue #33 came with the sad news that Heroku is no longer taking on new business and is moving into maintenance mode.

Heroku users can keep running things as usual for now, but it might be a good time to start looking at alternatives.

You're absolutely right, but this is a podcast about developer tools.

In this case, David was answering whether or not AI was a bubble. He says it is one (a bubble) because only approximately a billion people use tools like ChatGPT.

He estimates that 50% of the worldโ€™s engineers have yet to try agentic coding, and that at least 7 billion people still need to adopt LLMs.

@baweaver.bsky.social thinks this is possible with MCP tools.
