Posh TUI: March 2026 update

12 April 2026

Good day,

You’re receiving this email because you bought a Posh TUI license or subscribed. And this is an update for March 2026…


The Docset builder service (codenamed “Doczilla”) has been completed. I’m currently working on migrating the TUI client to the new APIs.

Why do we need a Docset builder service?

It’s a “Library Stalker” — it looks for gem updates, builds documentation, and publishes them to Content Delivery Network (CDN) for the POSH TUI client to consume.

This builder can monitor:

  • RubyGems updates
  • GitHub releases
  • plain Git repositories

…and tracks around ~1500 gems at the moment.


I’ve been looking for some business counseling. I’m an expat in the Netherlands, and this is my first business here. After some looking around, I decided to go with the OKB organization that provides business support here in the Netherlands.

Shortly after submitting a form on the OKB website. The next day my phone rang, and they asked me to write a Business Context Model (aka CANVAS). It’s a short business plan of sorts, that is very common around here.

I rewrote this eight-page document 4 or 5 times over the last couple of weeks. But once OK received this plan - The business advisor stepped forward to support me in less than 2 days. We already had our first 3-hour talk, where I laid out my marketing and monetization plan.

It was a very encouraging talk.


That’s all the big news for this month. I’m going back to mostly engineering now, so excited to show you what was cooking all this time.

Thanks for your support!
