What is an Unconference? 🔄 An unconference is a dynamic, participant-driven event where ideas flow, connections spark, and collaboration thrives! 💡It’s open, informal, and a completely different way to learn and engage—you might never look at events the same way again! 🚀 #SoCraTes #Crete
All the participants are seated in a circle arrangement of chairs inside a well-lit room. Only one person is standing in front of a series series of whiteboards that are filled with big sticky notes. The setting reflects a collaborative and participatory environment typical of an unconference and this photo specifically is of when the initial to the introduction to the unconference is done.

Modern DRAM is based on a brilliant design from IBM. But, we're still paying for a latency penalty that's existed since the 60s! In this video, I'm introducing my research project (Tailslayer) that immensely reduces p99.99 latency on traditional RAM!

Did you know you can develop your Quarkus app remotely on a Raspberry Pi? Neither did I. You can also cross-compile it to a native executable using QEMU to improve start-up times and memory footprint (if that's what you need).
