I like to think about my book "SELECT to Ship" as a tiny contribution to the software industry and application developers in particular. Link in 🧵👇

The TIOBE index for #Python shows it stable from 2004 to 2018 when it started to climb like crazy through the AI/ML boom. Then it hit an all-time record high in mid 2025. However, after that, it has been declining steadily. Python devs, what are your thoughts on this?

Alejandro Duarte @alejandro-du.bsky.social · 27/08/2026

TIOBE measures developer interest, not the amount of #Java running in production. Java remains strong in enterprise software, backend systems, and Android's ecosystem. However, is hard to ignore the trend. Java devs, what are your thoughts?

📘 Chapter 8 is ready! This took long to write. Months. But I'm confident it explains what developers need to know about transactions to use persistence frameworks like #Hibernate, #SQLAlchemy, #Sequelize, #MyBatis, and others more confidently. 👉 mariadbfordevelopers.com

Just explored Ignored Indexes in #MariaDB. Neat way to mark indexes so the optimizer doesn’t use them while still keeping them maintained. Great to check if an index is worth dropping without the risk of re-creating it later. How do you decide when an index is no longer useful?

So helpful! 😆 Anyway... with #MariaDB you have alternatives. Stop delayed replicas, check if you have backups, check the binary log... and of course, always use privileges to limit what the AI can do!
