Software engineers: Context switching kills productivity. Also software engineers: I'm now managing 19 AI agents and doing 1800 commits a day. We’ve spent years complaining that managers who expect a quick 5-minute chat ruin our focus for the next hour. But a ping from an agent every few minutes, that’s ok? We celebrated Paul Graham’s essay “Maker’s Schedule, Manager’s Schedule” in which he argued: “When you're operating on the maker's schedule, meetings are a disaster. A single meeting can blow a whole afternoon, by breaking it into two pieces each too small to do anything hard in.” Now we see software engineers claiming huge productivity gains from hordes of AI agents, celebrating thousands of commits per day from their 19 agents. Either context switching was never really the problem, and we oversold our need for deep focus. Or we're not actually reviewing 1800 commits a day. If we couldn't context switch before, we're not managing 19 agents. We're blindly trusting them. That’s not engineering, it’s gambling.

@kylewelch What do the numbers mean, though?

Perfect! Just in time for yearly reviews.

@springrod @spring_io @sergialmar Indeed! The only conference for which I gladly spend 2 days in a plane travelling all the way from Sydney. Hope to see everyone again next year!

Spring IO was the most fun I've had at a conference for years. Palpable attendee enthusiasm; interesting technical discussions everywhere; deep talks; and set in wonderful Barcelona. If you've not been, go next year! @spring_io Thanks @sergialmar for your hospitality

I'm excited to be speaking at Spring I/O 2025 on May 23 about how to sell (software) maintainability. See you there? #springio25

Simplicity--the art of maximizing the amount of work not done--is essential.

@simas_ch It's also harder, sadly 😪

IMO in DDD, the strategic design is way more important than the tactical design.

@sergialmar Happy Birthday! You still look young enough for me to confuse you with your your younger brother! 😀

I'm turning 40 today 🎉 Looking forward to the next decade and what’s coming next!

@nele_lea @bsansouci Did you get to see the bridge or was it shrouded in mist? I was in SF (the first time ever) a couple weeks ago so we just missed each other. When I went to see the bridge, it wasn't there...

Running event in SF, but no one’s sharing Strava—just LinkedIn and Twitter. Priorities. Jokes aside, it was a great way to kick off my Saturday. Thanks @bsansouci for leading it! Now back to growing my Strava followers.

This.

Watch my talk about Platform Engineering with Spring Boot for me so I don't have to (I hate watching myself) :)

@lorenzo_bettini Your name is still in it since you reviewed the english version 😀

@TomHombergs I'd have a hard time reviewing this version ;)

Look what was in the mail today!

German edition now available at mitp.de/IT-WEB/Softwar…

@rieckpil Nice! I'm still waiting for my copy. It will also be published in Japanese in July, if you want the full collection 😀

There it is 🚀 @TomHombergs book about clean architecture is now available as print in German 🍃

Relaxing in the airport lounge after @spring_io. I'm sad it's over, but it could be worse 😄

@spring_io was a great event again (as always). My favorite conference by a great margin! Big thanks to @sergialmar and the team for making it happen and caring for speakers and attendees alike. Find the slides of my talk here: speakerdeck.com/thombergs/plat…

What an amazing crowd! One more year finishing @spring_io with the classical bike & wine. #springio24
