What weโre about
### About ACCU York ๐ ๏ธ๐
ACCU York is a local chapter of ACCU, a global organisation dedicated to professionalism in programming. We meet most months in York to share ideas, grow our skills, and explore the art and science of software development.
Whether you're deep into C++, dabbling in Rust, building in JavaScript, or exploring functional programming and agile practices, you'll find others here who share your curiosity and want to learn alongside you.
What we do:
๐ง Monthly talks and discussions
From low-level systems programming to high-level architecture, we host engaging talks and conversations on a wide range of topics relevant to today's software practitioners.
๐ Cross-language focus
Weโre not dogmatic. C++, Java, Rust, Haskell, Go. Itโs all welcome. We believe the best developers learn from multiple paradigms and communities.
๐ฑ Professional development
We promote lifelong learning and craft in software. Whether you're early in your career or decades deep, ACCU is a place to grow.
๐ค Community and conversation
ACCU York is a welcoming space to meet other developers, share experiences, ask hard questions, and build connections. Free and open to all.
๐ค Propose a talk
Weโre always looking for new voices! If you have something to share. From war stories to wild ideas. Propose a talk.

Join us for thoughtful tech talks, great discussions, and a community that values quality and curiosity in software.

๐ฃ๏ธ Talk by Sam Cooper (๐ start at 19:00)
For years, people in and around Turkey have been used to seeing strange errors in popular software: Dropbox files failing to sync, Unity games freezing, Gradle builds crashing for no apparent reason. One security researcher even found a way to break into GitHub accounts using nothing but a Turkish email address.
The connection? A single alphabet character. In this talk, we'll take a hands-on look at some famous examples of the Turkish 'i' bug, including the years-long detective story of how locale-sensitive case conversions kept crashing the Kotlin compiler.
More importantly, we'll look at how you can avoid becoming the bug's next victim. We'll examine the faulty functions that make the bug possible, and see how to spot if your program, language, or library is affected. Then we'll check out the "Turkey Test"โa simple strategy for catching localization bugs before they reach production.
If you write code in any programming languageโor if you just like learning about weird software quirksโyou'll have fun following the trail of destruction left by this surprising one-letter bug. No prior knowledge required.

About the speaker: Sam Cooper
Sam Cooper is the author of Kotlin Brain Teasers and Kotlin Coroutine Confidence, both published by the Pragmatic Bookshelf in 2025. His tech writing has also featured in community publications like Kotlin Weekly, Android Weekly, and Software Testing Weekly, and has even hit the top of the Hacker News front page.
Sam spent many years crafting developer-facing APIs and high-throughput backend services in Kotlin at Anaplan, where he was a Principal Engineer and tech lead. Before that, he worked at Amazon Web Services building multiplayer games infrastructure in Java. Sam holds two Master's degrees: one in Computer Science from University College London, and one in Modern Languages from the University of Oxford.
His motto (which he stole from a former boss) is "speed through quality": he believes (with receipts) that "cutting corners" in programming is a myth, and that clean, well-tested code always gets you to your destination faster.
