I've felt like most embedded languages have been moving towards safety and typing over years, with things like Python type hints, the explosive popularity of typescript, and even typing in Luau, which powers one of the largest scripted evironments in the world.

Bolt attempts to harness this directly in the lagnauge rather than as a preprocessing step, and reap benefits in terms of both safety and performance.

I intend to be publishing toys and examples of applications embedding Bolt over the coming few weeks, but be sure to check out the examples and the programming guide in the repo if you're interested!

The problem: When learning a new technology, the best insights often come from how companies like Google, Meta, or Stripe actually implement it in production. But these gems are scattered across dozens of separate engineering blogs with no way to search across them.

What I built: Engineering.fyi indexes engineering blogs from ~15 companies (Google, Meta, OpenAI, Anthropic, Stripe, Uber, etc.) and makes them searchable in one place. You can filter by topic, difficulty level, and whether articles include code samples.

Technical details: - Built with Next.js, SQLite, DrizzleORM - Custom scrapers for each blog (they're all frustratingly different) - Basic tagging system using content matching (still improving this)

Current status: Core search is working. Adding new blogs weekly as I index them.

Next features (based on early feedback): - AI summaries for quick article previews - Weekly digest of trending engineering insights - Save/bookmark articles (considering whether to add accounts)

Interesting challenges: - Each blog requires custom parsing logic (no standard format) - Building an accurate tagging system is harder than expected – started with exact matching but exploring better approaches

I'd love feedback on: - Which company engineering blogs you'd find most valuable to include - Whether AI summaries would actually be useful or just noise - How you currently discover engineering articles from these companies
