Family - or, more generally, the people who depend on me - is probably the main reason that the self-destructive forces within me stay at bay.

For the next release it would be nice to roll out a couple of more 'tools' for LLM's.
- Token counter
- JSON to TOON converter
Toon is a nice little format, that helps optimize token usage with LLM's.
If anyone wants to take a stab at it - I'll be happy to see PR's.

devtui v0.30 is out!
- 'JSON Repair' TUI and CLI interface was added. Really useful for fixing JSON output from LLMs.
- Also multiple small performance improvements.

One of the best purchases this year.
It's only a second week since I have it and I'm finishing my second book with it.
Mostly read in small breaks.

My son reads comic books at the rate of 4 books a day. That is roughly 40 euro a day.
I'm trying to calculate, which will happen first - I will run out of money or we will run out of comic books to buy?

Ruby Central was a questionable organization with zero transparency even before all the drama started.
I deeply care about the ruby ecosystem, but still give RC zero $. I would always actively advise against providing any funds to RC.
Better spend that cash to improve the gems company relies on.

I used to enjoy working remotely from home, until I built a salon for my wife there.

being too small for the big players is basically a cheat code
they can't be bothered with "tiny" markets
meanwhile we're stacking up little empires, one micro-niche at a time
let them fight over "who's gonna build the best LLM"
we'll take the weird corners

It's so fun to build prototypes with AI- it's impossible to stop.
I had a huge list of apps I always wanted to try and build. And now is the time I can do that!

A quick update on POSH TUI project.
It was radio silence for a while, but I have written down a future roadmap for the project.
I'm currently filling out some papers/formalities to enable this R&D work and get some tax discounts (and maybe even EU funding).

After listening to about a dozen first-hand accounts, I’ve published what I know about the RubyGems takeover.

I really appreciate your post @apiguy.dev. Thank you for posting your thoughts. I wish you had the info I had to make your decision.
Here's the core issue:
Before Sept 9, when a trusted maintainer broke our shared contract and added an RC non-maintainer, you had no ability to enact your vote.

Having met with both sides on the current RubyCentral/RubyGems situation, here's my take:
- RubyCentral have managed this exceptionally poorly in many ways including removing literally the most active member of the RubyGems organisation by mistake who has declined to return
