Systems with highest truck factors
🤓 The truck (or bus) factor measures the number of key people who would need to be lost (for example leave the team) before a software project is seriously compromised or unable to continue. This paper from 2016 proposes a method for estimating this factor.

.... and of course it failed because I didn't cd 🤦♂️ too eager!
Here we go...
Something similar almost happened to me once while I was playing with the #MariaDB MCP Server. Fortunately, I was running it in read-only mode, and the project was a simple demo. It was an eye opener nevertheless.
AI Agent fail
⚠️ Be very, very careful with "YOLO modes" when running AI agents. This kind of thing happens. See this GitHub issue for a real-life example:

Lazydocker doesn't provide a built-in option for running new containers. Here's how to add it.

For those who attended my talk "RAG Without the Plumbing" in #Brussels with the #MariaDB Foundation, here's the video about vector embeddings that I referenced.

🙏 Thanks to everyone who joined my talk "Deploying RAG Without the Plumbing," and to the MariaDB Foundation for organizing the event. As always, I had a blast interacting with software developers working on real projects with MariaDB 👏

Playing around with something new. I’ll share more when I get this ready in a few days.
My colleague Jags Ramnarayan is speaking tomorrow on how #DBAs and #Developers can build out AI Agents for database management with #MariaDB. Free event.

Still using #MySQL? Stewarded by Oracle, MySQL has been in decline for years. Stop using it in 2026, especially if your care about the #opensource #FOSS methodology and not just the license.

Learn key vocabulary and concepts like vector embeddings, semantic search, RAG. In this video, I use #Java and
@mariadb.bsky.social but most of the concepts apply to other programming languages and databases as well.
MariaDB ignored indexes in action.
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?
🚀New release: @mariadb.bsky.social Connector/J 3.5.7.
Time to update your #Java Maven pom.xml files... or build.gradle of course!
🙋 Anybody using Lima for easily creating #Linux virtual machines? Here I'm emulating x86 on ARC which I needed for demoing #MariaDB Enterprise Manager. It supports x86 on ARM, ARM on x86, and native setups.
It's a project from the Cloud Native Computing Foundation. Check it out at lima-vm.io
Frequency writing SQL manually. If you are starting your career in the software development industry, you must learn SQL. There are plenty of good resources online. My 2 cents 👇

🤩This is so cool! #MariaDB Enterprise Manager automatically creates a fully-configurable #Grafana dashboard. Great tool for teams handling mission-critical workloads with MariaDB.

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!
