It’s been an amazing and rewarding experience running All Aboard Bootcamp and today I’m really happy to be able to announce https://t.co/20fvZKQ19L where you’ll find a write-up of how everything went, complete session videos, & of course.. contact info for each of the graduates!!

A lot of times in the closing days of a presidential campaign, large accusations of impropriety surface. We have these examples ready at hand for one candidate, but the fact we don’t have them for the other is an indicator of high character and a career of service. Vote smart.

@philsturgeon 😂

[John Crepezzi @seejohnrun]

@philsturgeon Did they teach you any sick bails?

[John Crepezzi @seejohnrun]

@philsturgeon Tried, or did?

The current generation of AI models could remain unchanged for the next 10 years and we’d still be finding novel uses for them.

Anyone thinking AI is a doomed because the models have reached some limit is missing the point (and also likely wrong).

@corywilkerson Aww 🥰 miss you Cory

What are you doing in here?!

My username is the same pretty much everywhere 🧵

Who is going to tell the people that make Final Fantasy what “final” means?

[John Crepezzi @seejohnrun]

Fun episode - if you’re not a listener already this is a great place to jump in

[Kyle Daigle @kdaigle]

I guess you can go home again. ⚡️ Thanks to @BrittJMartin for inviting me back to the @therubyonrails to talk about GitHub, AI, and my journey from developer to COO at @github. Had a total blast!

[John Crepezzi @seejohnrun]

It’s not the first time this person has been in tech news, and also not the first time that 90% of the people at the same place wondered “who tf is that?”

Try not to assume that everyone with the same employer are somehow bffs :)

(shoutout to all my real bffs - you the best)

@andreasklinger Bots that work with you actively instead of just auto-completing, testing tools that auto-discover and cover behaviors, systems that discover issues or optimizations with software as it runs, & drastically different types of programming languages

[John Crepezzi @seejohnrun]

In case it’s not clear from my recent albeit sporadic tweets, I’ve been spending nearly all of my time working on developer tools (as always) with AI/LLMs. This, right now, is a phase shift for tooling that will change what it means to be a developer within the next decade.

It’s fun that we all have learned to tolerate the capitalization of “Lol”, and that Apple has absolutely refused to do anything about it.

[John Crepezzi @seejohnrun]

@RyanCaldwelll @jhawthorn Yes I’d love to bring these back! I’ll chat with John and figure out a time ❤️ 🎉 glad you like them and thanks for asking about this

[John Crepezzi @seejohnrun]

@mscccc Just hit rebuild 5-10 times until it passes lol

[John Crepezzi @seejohnrun]

@mscccc And it still feels like we’re near the beginning. Forthcoming: integrations into build systems, test systems, architecture & of course the programming languages themselves
