@tdpauw Indeed. Even a talk about an AI driven can opener would be accepted at tech conferences these days.

On 𝐅𝐫𝐢𝐝𝐚𝐲, 𝐌𝐚𝐫𝐜𝐡 27, I’ll be presenting "𝐞𝐗𝐭𝐫𝐞𝐦𝐞 𝐏𝐫𝐨𝐠𝐫𝐚𝐦𝐦𝐢𝐧𝐠 – 𝐓𝐡𝐞 𝐊𝐧𝐨𝐰𝐥𝐞𝐝𝐠𝐞 𝐖𝐞 𝐋𝐨𝐬𝐭” at 𝐝𝐞𝐯𝐂𝐨𝐧𝐟 2026. This talk is a deep dive into the origins and core practices of XP, and why these ideas are still very relevant today. Let’s reconnect with the principles that shaped modern technical practices.
🔗 More info & registration: https://devconf.nl/
Looking forward to seeing you there!

When learning Test-Driven Development (TDD), developers often struggle with identifying boundary conditions and exceptional cases. One resource that has been incredibly helpful to me over the years is the 𝐓𝐞𝐬𝐭 𝐇𝐞𝐮𝐫𝐢𝐬𝐭𝐢𝐜𝐬 𝐂𝐡𝐞𝐚𝐭 𝐒𝐡𝐞𝐞𝐭, created by Elisabeth Hendrickson, James Lyndsay, and Dale Emery. This concise document provides a wealth of inspiration for uncovering edge case scenarios.
