The more I work with AI (both ChatGPT and Claude) the less I believe engineers should be worried to be replaced unless they are doing extremely trivial work.

Software engineers should not be concerned about AI replacing their jobs (for now) unless they are performing extremely trivial tasks. I have paid accounts for ChatGPT and Claude, and although it can be useful, AI is typically on massive amounts of LSD.

eBPF technology is very sweet. I have been working on a CPU stall detector to determine the cause of latency outliers. And being able to hook into various points of the system (Java and OS) is super nice.

It has been more than a decade I have used aspect-oriented programming, but with ByteBuddy it is pretty sweet. Working on an Aeron async-profiler agent for latency profiling and an Aeron HdrHistogram agent for latency tracking over time.

In Java, when final will mean final, it will cause networking code to create litter. Because the Selector hack to replace the litter producing hashset by something that doesn't produce litter, won't work any longer. Netty and Aeron are some projects that apply this trick.

A nice thing about working at @WeAreAdaptive is that you get to see presentations long before the general public can see them.

A load generator can only properly deal with coordinated omission, if the latency is determined based on the scheduled starting time and not the actual starting time.

Ad posted on LinkedIn messages; what a terrible idea. The content generally is terrible with all the self proclaimed guru's, but this increases the level of spam even further.
