Robby's slide says "The Mythical Agentic Man-Month" I mean, I do not think the framing is original to me… I was trying to get something at 10x, but there's no real word for anything between a week (4x) and a day (30x). "The Mythical Agent half-week" didn't really have a ring to it

For a mythical prize, anybody want to guess where the font is from?

This is a fantastic talk and I can’t wait to share it.

We do not know the long term effects … of using AI tools on projects at scale. - @noelrappin.com

Wrote a thing about last week's Rails World. andycroll.com/ruby/look-a...

I was searching to remember when the first Windy City Rails was and found this blogpost from @andyatkinson.com who was also there… andyatkinson.com/blog/2008/09...

This conference is about celebrating YOU. 💙 So after chatting with a bunch of you, we made three changes to the event: - We changed the name back to SF Ruby Conference. - We updated our keynote speakers because, unfortunately, Garry Tan can't make it anymore. - Day passes are now for sale.

Okay, the cover isn't attached yet, but Programming Ruby 4.0 now has an Amazon Pre-Order for the physical book, which is winding its way through production.

New blog post / newsletter, continuing the When Books Could Code series, specifically continuing the discussion of Extreme Programming Explained, this time covering the original 12 practices and what happened to them…

Having turned in the extensive translator-driven revisions to Pickaxe 4.0 and 3.3, I find myself without a book project, or even the idea of a book project, for the first time in... 20 years? It's a weird feeling.

My Robot Year. The underserved genre of LLM takes… as I come up on a full year of working with Claude. Prototypes vs finished products, exponential complexity, and Conway's Law with robots. Actually finished this because I was afraid the world would change three more times if I waited.

And while I'm here, the season premiere of Strange New Worlds was one of the Trek-iest things that ever Treked (complimentary). The bones of this story would have worked on Next Generation, would have made a great Voyager episode, even a fun Lower Decks episode...

Well, I for one did not know that a theater here in Chicago is going to be adapting Becky Chambers' "A Psalm for the Wild-Built"... lifelinetheatre.com/performances...

My talk is tentatively titled "Inspector Gadget: Adventures in Agent Code Review", and it launches from the weirdness of asking an LLM "what would <a Ruby Luminary> do?"

OK, so the paper version of Eloquent Ruby is off to production. That means it's a couple of months away from making an appearance. It also means I'm done, with a capital "Ahhh." pragprog.com/titles/eruby...
