It is amazing how quickly things can change for you if you manage to just get a single “yes.” In 2019, bored on summer break from college, I randomly emailed a book proposal to @pragprog. Miraculously, they said yes
After the book was published, I was introduced to @josevalim who crazily said “yes” to sponsoring some early work on ML in Elixir, from somebody who had zero OSS experience and very little professional experience
Both of these things basically kickstarted my entire career. Because of a couple of people saying “yes” I have been able to work on many cool things, and hopefully many more! It is important to remind yourself that a single “yes” benefits you far more than 1000 rejections hurt you

Func Prog Conf 2026 is gonna be lit! Both @enigma2a and @AdamTornhill are speaking. And we're hosting a warmup #Clojure Café the night before, with Arne Bresseur speaking (probably about Janet Lang).

The secret to better software isn’t *more* code, it's *smarter* code. With clever examples and insightful illustrations, @jaywengrow helps you really understand performance and ship Python that scales.

The "whiteboard defense:" I should be able to pull you aside at any moment and ask you to explain any customer-facing system you've shipped. You should be able to clearly explain how it works and defend the decisions you made. This is my benchmark for responsible AI usage.
I don't expect line-level familiarity with the code. I don't care if you remember the exact function name or implementation detail. You may not even know it. I don't care.
But if I ask "why did you do X instead of Y?", "what happens if this actor behaves maliciously?", "what data structure did you use here and why?", or "where does this fail?" you should be able to answer confidently.
For PoCs, demos, experiments, whatever: I don't care. Generate 100% of it and understand none of it. Speed over quality every time in those specific scenarios.
But if you're shipping customer-facing work, you can't be shipping things you don't understand at a high level.

At Rustconf with @ardanlabs , shamelessly promoting Advanced Hands-on Rust for @pragprog !
A Common-Sense Guide to Data Structures and Algorithms in Python, Volume 1 by @jaywengrow
"Students and programmers everywhere are told how important algorithms and data structures are for creating quality software---not to mention getting hired at the best companies---and yet, there are so few resources that bring actual clarity to the topic.
This book does!" -- Lyndon Purcell, Software Developer, OK200.

Complexity is inevitable. Tangled code isn’t.
Advanced Functional Programming with Elixir by @joekoski_wa
Use real-world Elixir in FunPark as the working domain, and a production-ready, open-source library you can use and extend into your own projects. Core abstractions like equality, ordering, predicates, monoids, and monads can become practical tools that help you build software that stays understandable as it grows.
For Elixir developers ready to go deeper into functional programming—and functional programmers ready to explore Elixir.
