I am so EXCITED (and honored) to be presenting at DevNexus in March 2026!!!

I'll be talking about one of my favorite coding activities: Refactoring #Java in IntelliJ IDEA! Even if you're an experienced coder, I'll bet you'll still learn a few new things to try out...

First time in a while that I've given a talk (a TED TALK as @danvega.dev reminded me!) as short as 25-minutes! Amazingly, it fit exactly and the recording will be available soon at www.commityourcode.com #CommitYourCode

Slides are available at ted.dev/talks/

Is it "AI"? We might start calling it "AI", but apparently once we understand it, we call it something else...

#DevoxxUK @tomcools.be
Tom explaining where Timefold fits: the slide is 3 nested circles, the outermost is "AI" (where Timefold fits), nested inside that is Machine Learning, nested inside that is "Gen AI"

Timefold will try to solve for the (hard) constraints, but if it can't find a solution, it will at least give you a solution (instead of just giving up). You can then go back to the business—maybe they need to hire folks, or maybe relax a constraint.

#DevoxxUK @tomcools.be
Tom answering a question about constraint scoring, next to a Timefold view of the score showing that it did fulfill all hard constraints, and minimized the "soft" constraints.

When you start comparing things to the number of atoms in the universe, you know that brute-force is not gonna work.

#DevoxxUK
Tom Cools pointing out that the atoms in the universe is on the order of 10^80, but the shift scheduling problem is on the order of 10^221 (141 more zeroes!)

There's a built-in assumption here around what "testing" means...
Paul talking through a slide about Challenges with testing: • Requires development effort • Difficult to outsource • Engineers would rather be writing code • Engineers are human • Humans are not good/disciplined/fast at doing things they don't want to do • But Al can be good - if it can be trusted!

Checking out the automated test writing competition...

#DevoxxUK
Title slide for presentation: "Agentic Al-driven unit test generation you can trust" What use are Al tools if they fail to meet developer's expectations for accuracy and consistency?

You can tell @garnier.wf's 2-hour deep dive session on "Spring Boot Testing" was packed full of useful tips, because I didn't have any time to post anything during the session!

I took one pic to remind me about #SpringSecurity and csrf when doing `WebMvcTest`.

#DevoxxUK #SpringBoot #TestingIsGood
Security testing: utility methods * Compatible with @WebMvcTest * @WithMockUser for injecting simple users * @WithUserDetailsService * SecurityMockMvcRequestPostProcessors for MockMvc(Tester) * . csrf(), .opaqueToken() , .oidcLogin() ... * ... and more!

Who is helping your team Level Up? Peers and line managers probably may not have the experience in technical _coaching_ and the time to do it as needed.

Love that @emilybache.com throws the #TDD cycle right up front, because "the higher the code quality, the less time it takes to add a feature"

Where #SoftwareArchitecture might have gone wrong: treating the architect as the expensive resource and the rest as "coding monkeys" (i.e., cheap[er]), but this leads for bottlenecks, lack of deep context of individual teams. This is not a recipe for success... #DevoxxUK @einarwh.bsky.social
