SF Ruby AI Hackathon · Luma We are thrilled to announce a community-driven Ruby AI Hackathon on Saturday, July 19, 2025 at the Sentry office in San Francisco! 🎉 Hosted by the SF Bay Area…

Deets: Join us on July 19, 2025, from 10 AM to 5 PM at Sentry’s office in San Francisco. RSVP at lu.ma/znhcct7v, more info soon!

PSA: SF Ruby is hosting an AI hackathon… and I’ll be there too! Rails has always been the go-to framework for solo developers. So here’s the big question: *exactly* how much further can we take Ruby specifically with LLMs? Let’s find out!

(i say this in a slightly disappointed tone because I don’t really like tdd)

claude code is very very bad at writing tests and will always try to make the job easier for itself by cheating, BUT it’s very very good when it can iterate against a good set of tests, so perhaps this means tdd is the best way to program with an assistant

How would you go about optimizing an existing large codebase to incorporate generative AI?

Sure, there are a lot of non-programmers sharing opinions about the future of programming right now, but to be fair, programmers have had plenty of big opinions about the future of non-programming jobs these past few years (?) too. How the turntables.

OpenAI never lost the Mandate of Heaven.

“May you live in interesting times.”

Haha, I missed it too—just watching from a distance, safely from Poland. Nothing happened in the end.

A tsunami warning and a tornado warning in just 10 days. Is that something that often frequently in SF? Asking, well, for myself.

Nothing, it’s only natural after such a huge influx of new users. Just keep growing naturally.

$NVDA: hold or sell? 😅

Haven’t tried it myself yet—price!—but I’ve encountered similar issues in the past, so, yeah.

Leaning towards “good” more often than not now—especially o1 pro.

Everybody who complains about Ciri being the main protagonist in The Witcher 4 just lost all their credibility in complaining about games being “woke.”

Agreed!

Had a day like that this week. Victory rarely tastes so sweet!

Prediction: The more OpenAI wants to get out of their deal with Microsoft, the more we’ll see an inflation of the term AGI being thrown around.

Nice, another regulation to keep track of, so happy to hear that. /s

o1 vibes based on my feeds: sometimes maybe good, sometimes maybe shit

OK, I didn’t expect a tsunami warning today.

I’ll look into this over the weekend. I’m traveling long-distance, so I won’t be able to get to it sooner. Could you create a GitHub issue in the repo, please? That way, I won’t forget. Thanks!

Introducing Lammy An LLM library for Ruby

If you caught my presentation yesterday at SF Ruby & AI, here’s a quick summary. I talked about Lammy, my LLM library for Ruby that’s simple to use and treats prompts as programs rather than plain strings.

Another SF Ruby starting soon!

Just wrapped up preparing my talk for next week’s SF Ruby & AI event. Now I can look forward to it with peace of mind!

💯

It’s not a primary one but definitely one of the main three—alongside Twitter and newsletters.

Good news!

Kudos! I bought the early version but wanted to wait for the full release before reading it. Now’s the time!

It’s not a big deal to me personally. Only Twitter had its own unique term. On every other platform, like a blog or Facebook, you always had to specify where you posted.
