🙌 "#1BRC--Show & Tell" While the core challenge is Java only, this is a treasure trove of folks show-casing implementations using other languages (e.g. Go, Zig, C++, Rust), databases (DuckDB, Snowflake, ClickHouse), and tools (awk). 1⃣🐝🏎️ github.com/gunnarmorling/…
@ScottWlaschin - Remove what is actual simple, easy and working. - Create something more complicated and give it a cute new name "Single Page Application". - Realize that things got more complicated and less efficient. - Back to what was simple, easy and working than give it a new name.
AI won't replace programmers. Programmers who don't use AI will be replaced by the ones who do. AI is just another very useful tool that each and every developer should have in his/her own toolbox.
Black & white thinking is limiting, because when you can always tell yourself, 'They're the problem, they deserve it!' then you will never appreciate other people's values, perspectives, stories, and (limited) knowledge, nor see your own contribution to conflict.

Periodic reminder for #Java devs still on 11: don't ignore "Illegal reflective access" warnings in your logs! This WILL cause your app to not work when migrating to 17. Course of action: 1⃣ Remove in your code 2⃣ Upgrade 3rd party deps 3⃣ Log issue/PR with deps if still an issue.
Cutting corners does not mean cutting quality, it means cutting features.
"Can we shut up and just write code?" - Jessica McCay
My approach to testing: - Aim for the vast majority of code to be pure functions with plain old unit tests. - Use Testcontainers for integration testing of effectful parts. - If needed, create mocks for the effectful parts.
The compiler is the first tester of your code.
Example of "make illegal states unrepresentable" based on an API I just encountered... If a function can handle a variety of things but must handle at least one kind of thing, don't just use a single vararg param, require at least one of the things then vararg the second param:
I love working on a feature with nothing but a pen and a notebook. 📖✍️
What is the most 🤯 programming paradigm you’ve experienced in the past decade? For me it was the Elm architecture.
For all the folks who love to perpetuate the myth that its only the LTS releases that count, this is an excellent reminder that every Java release is a full-feature release, packed with hundreds of small improvements and fixes. #MovingForwardFaster
