Picard management tip: When you've gotten enough sleep, an impossible task becomes an interesting challenge.

Picard management tip: If people accuse your organization of endangering people who wear red shirts, put on a damn red shirt every day.

What amazes me every now and then is that there is software out there that actually works.

Picard technology tip: An advanced system isn't always easy to use. Improve the interface, or try pushing buttons at random.

Picard strategy tip: Pick your battles. Fight injustices before annoyances.

Testen und Qualitätssicherung bei Startups - Richard Seidl Wie gelingt Software QS in Startups ohne starre Prozesse? Experten zeigen, was wirklich zählt und wie es läuft.

It's such a cool thing to hear people still remember your impact many years later, and that things are still going well thanks to the foundations you've laid. Listening to this episode literally made my day. 🤩 www.richard-seidl.com/de/blog/soft... (in German) 2/2

Today was a good day. Until it became awesome when an ex-colleague pointed out a podcast episode in which my former CIO talks about their company's testing and quality culture. And kindly mentions me a couple of times, pointing out my contributions. 1/2

The rise of AI in testing means we can't just rely on tech; our human curiosity and critical thinking matter even more. Don’t take shortcuts—question what the machines produce and keep your skills sharp. My interview with Steve Watson: tul.fm/iyvz

Terminal output indicating LLM usage – cost $0.10, took 87s, burnt a tiny hole in my soul.

Yesterday, Claude successfully (and painfully) got authenticated with my repo.
Today, I could not work out how to authenticate personally through the commandline (I have a passcode, it needs a password).
So I'm reduced to spending $0.10 to ask the LLM to do `git push`.

WAAAAAAAAAARGH.

Our Solar System is orbiting the center of our Galaxy at about 220 km/s so in 2025 we collectively traveled something like 7 billion kilometers across the Milky Way. Once in a while, when you have a moment, it’s worthwhile to take a look around, see where you are, and appreciate how far you’ve come.

Picard management tip: Don't negotiate absurd schedules with engineers. Encourage truth telling and reasonable time estimates.

The two hardest problems in Computer Science are

1. Human communication
2. Getting people in tech to believe that human communication is important

A foggy day at the North Sea on Nordstrand in December 2025. Going for a – short! – swim in 6°C water. (And then to the public pool for a longer swim in water that's 20 (℃) degrees warmer.)

Huge thanks to everyone: #AgileTD participants, speakers, volunteers, and especially the lovely organizers - you make this unique event happen for all of us, I'm deeply grateful for this space. See you in 2026! 🦄 2/2

Had a blast teaching Playwright on Monday!
Now gearing up for Thursday's mission: CSI: Flaky Tests.
We're investigating the crime scene of unstable automation to uncover the root cause: flawed assumptions about system state.
Come ready to solve the case!

Leaving @agiletdzone.bsky.social. Always love to visit Potsdam so I went for a very quick quick walk before departure. I love the event and every year I make some new friends. Also good to revisit the old ones, sometimes it is hard to find the time to be with everybody :) see you soon ;)

That's it! 🎉 Another edition of my workshop "Secure Development Lifecycle Applied - How to Make Things a Bit More Secure than Yesterday Every Day" done, this time together with Santhosh Tuppad as a special bonus. 🦄 Loved seeing the #AgileTD crowd enjoy practicing security from idea to production. 🤩
