In general I'm finding finely tune Copilot agents extremely helpful in all sorts of migration scenario!
Still running Spring apps on SQL? 👀

See how to evolve to Azure #CosmosDB with #GitHubCopilot as your migration buddy.

🧠 Live demo + real refactoring examples!

At #devoxx today? Do stick around for the closing keynote (m.devoxx.com/events/dvbe2...) at 18:50. I know it's late in the day after a long conference but I promise it'll be worth it... Truly!

Hey #java #developers heading to #devoxx next week. As a quick preview of my *Rise of the Rogue Agents* talk (m.devoxx.com/events/dvbe2...), here are two of the little tyrants arguing with each other about dependency upgrades 🔥🤖.

I’m privileged to be able to travel a fair amount for work. I still weirdly enjoy airports and seeing so many people connect with loved ones, be excited about a destination, or hopeful for a change in their future! The kid currently making faces at me is also pretty entertaining 😂

This is a PSA for folks using old, maintained container images, even though we are targeting the ones we host, this is a good reminder for y’all to check yours! #k8s #java

First major #cat injury - Mando (short for #Mandalorian) has a broken tail, so off to the vet get goes! We like to think it was earned battling the empire this morning…

Always cool to see a book you’re involved with get translated to non English languages! Points goes to folks who can pick which language without using #Ai 😉

Today I ripped out a bunch of weeds in the garden and cut down an invasive species. If this was #linkedin I’d make some analogy to cleaning up #technicaldebt but luckily this isn’t LinkedIn

So what’s the protocol now - post the same post here and on #Mastodon or does that annoy y’all who are on both?

Kiddo is at his first school camp - he’s having a blast and my wife and I have gotten more done around the house in one day than we have in weeks! I never internalised how interrupt driven a typical family day is. Good parallel for having those meeting free days at work so folks can get stuff done!

Will be scoring at my son’s #cricket game tomorrow. Two observations - kids all geared up at age 9 is one of those strange “oh they’re growing up!” moments as parent. The other is that I’m glad I have a Comp Sci degree behind me coz scoring this game is archaic as heck 😂

Was reviewing Porter’s Five forces again with @brunoborges.bsky.social tonight - great trip down memory lane when we applied this to jClarity during its life before acquisition. Recommend using models like this to help reduce uncertainty when you’re in a new domain. Like I was as a first time CEO 🙂

Hey all, on my profile it says my handle is invalid, but I can’t see a a way to edit on my mobile app (iOS) - any ideas before I ask #chatgpt? 😃

Had a #fail in setting up folks for success presenting to a very senior leaders. When reviewing the material, I didn’t see enough concrete conclusions or asks but I hesitated and didn’t postpone it. The presenters did great! But the reaction was muted at best. Hope folks can learn from my mistake 🙂

Thank you and keep them coming folks!
I just submitted two session proposals for #jdconf 2025 🤞What about you @martinelli.ch @marcushellberg.dev @lawrencedlockhart.bsky.social ?

Back to sharing idle short form thoughts 🙂. #genai like #copilot and #chatgpt have enabled me to be a 1-person triage customer support machine. I can take the accountability to front up to customers giving robust feedback *and* 90% of the time give them a path to resolution, and it’s actually fun!

Gosh this platform got real busy all of a sudden. As they say, competition is good 🙂
