Today I gave my workshop "GitHub Actions in action" for a very engaged group of people at Testing United.
Tomorrow conference day, lots of promosing talks I'm looking forward to.

And then home and finalizing my sessions for @agiletdzone.bsky.social!
Christian, a bearded man wearing glasses, a black hoodie, and a patterned cap, takes a selfie next to a large digital display. The screen shows a bright blue welcome message for the Testing United conference with a stylized city skyline graphic. Reflections from the surrounding indoor space are visible in the background. Participants of Christian’s “GitHub Actions in Action” workshop sit in two rows at long tables, each focused on their laptops. Some type intensely while others listen or sip coffee. Power strips, notebooks, water bottles, and backpacks are scattered across the tables and floor. The room has neutral walls and open doors in the back, giving a glimpse into the conference space outside. A digital screen outside a workshop room displays information for a Testing United conference session. The slide announces a half-day workshop titled “GitHub Actions in Action,” scheduled for November 13 from 1–4 PM. On the right side is a professional portrait of Christian, wearing glasses, a flat cap, and a checked jacket. The conference logo and “Organized by Krone” appear at the bottom.

Travelling with German railway always means asking yourself: Is this piece of software behaving weirdly, or I'm just offline?! 📶 📡
A playful Simpsons-style parody of the classic Chrome “No Internet” error screen. A yellow cartoon dinosaur resembling a Springfield character stands on green grass beside the bold text “No Internet.” Below, humorous troubleshooting tips read “Try: Checking the network cables, modem and router. Reconnecting to Wi-Fi.” The bottom line shows “ERR_INTERNET_DISCONNECTED.”

My 11-year-old nephew is celebrating his birthday tonight with his friends: a sleepover party with a night hike.
This is what will haunt them during the hike! 👻
I am so much looking forward to it! 😂
Christian wearing a long, dark hooded robe with ornate trim and large toggle clasps. He has pulled a pair of women’s tights over his face, giving it a distorted, eerie look. The three black-and-white photos show him posing indoors: arms outstretched in the first, a close-up under the hood in the second, and standing straight with the hood up in the third. The overall atmosphere is dark and unsettling, resembling a creepy or horror-themed scene.

Changing wheels 🛞 on the car 🚗 has only to be done twice a year, and it's one of those activities I would like to procrastinate on for months, although it's done in less then 45 minutes. ⏲️ 🙈
Luckily, for this autumn it's now done.
Four stacked car tires with rims stored indoors against a white wall, two of them marked by yellow autumn leaves stuck to the rubber surface. The tires are slightly dirty, resting on a tiled garage floor near a closed door.

I'm brainstorming with the help of Claude on things to discuss with workshop participants, what questions to ask.
Interestingly, it doesn't headline them "Questions", "Points to discuss" or the like, but "Prompts". Is it assuming my participants will be LLMs? 🤔
Screenshot with the heading “Discussion Prompts” and three bullet points: “Which file made you smile? Which made you wince?”, “If you could refactor only ONE thing this sprint, what would it be?”, and “What pattern is missing that would give biggest leverage?”

Finally! 😆🤩
Apparently all that was needed was a bit of venting on social media.

Thanks Tobi! At least I'm well equipped with ducks! 🦆
Three rubber ducks are sitting on a laptop keyboard. The left duck is white with a unicorn horn and purple beak, the middle duck is yellow with an orange beak and a “POSTMAN” logo on its chest, and the right duck is black with orange flames painted along its sides. The laptop’s screen shows a terminal window with code running, and desktop icons are visible along the top edge.

Wednesday, 5 pm: It feels like I'm close to solve this coding issue.
Wednesday, 5:30 pm: I quit, I've been at the desk for 10 hours, and I have other things to do.
Thursday, 9 am: Two more hours into fixing the issue, and it feels like I'm nowhere close to solving it!
A four-panel comic from CommitStrip humorously depicting programmers debugging. 1. Panel 1: A bearded developer celebrates, arms raised, shouting, “Booom! Look at that! Who’s the Jedi master here?!” while his frustrated coworker sighs, “Ugh…” at his desk. 2. Panel 2: Another colleague enters, asking, “What’s going on?” The seated developer replies, “We’ve been stuck on a bug for 2 hours…” The bearded developer wears a party hat and pops confetti. 3. Panel 3: The newcomer asks, “…and he fixed it? Well done.” The seated developer responds, “No no, not quite…” as the bearded one dances joyfully under party decorations. 4. Panel 4: The bearded developer says, “Ahh!! It feels great to finally make progress!” The seated one explains, “The bug is still there, but now the error message is different.” The newcomer looks thoughtful, saying, “Hmm…”

Day 7 as a first timer on a Mac.
This is my life now! 😱😂
Screenshot of a productivity setup for keyboard shortcuts research. The screen is divided into four quadrants showing multiple browser tabs and a text editor: - Top left: A dark-themed text editor (likely VS Code) with a markdown file titled “keyboard.” It lists keyboard shortcuts for IntelliJ, Fork, and Chrome (e.g., `⌥⌘P`, `⌘SHIFT+R`), and includes links to Unicode character references for macOS. - Top right: A web page titled “The most common Unicode Characters on macOS” from *adoc.studio*, showing a clean white table with Unicode symbols (arrows, Apple logo) and their codes (e.g., `U+F8FF`, `U+2190`, `U+2191`). - Bottom left: A JetBrains documentation page for IntelliJ IDEA titled “Coding assistance,” listing predefined macOS keymap shortcuts like “Basic Completion (`Ctrl+Space`)” and “Reformat Code (`⌥⌘L`).” - Bottom right: An Apple Support page in German, titled “Ausschneiden, Kopieren, Einsetzen und andere häufig verwendete Kurzbefehle” (Cut, Copy, Paste, and other common shortcuts), showing common macOS commands such as `⌘X`, `⌘C`, and `⌘V`.

Random thought: Lots of people have different understanding of the same terms. Working in a team, we sooner or later (hopefully) come to common understanding of the terminology used.
In a conference talk, explaining what you mean by certain terms is crucial so the audience understands your message!
Comic-style scene inspired by Asterix: a Gaulish speaker wearing a winged helmet stands on a wooden stage during a village conference, pointing seriously at a sign that says “Concept – Feature – Model.” In the audience, three villagers look confused, each imagining something different when hearing the words: one thinks of an axe, another of a mountain, and another of a blonde woman. Speech bubbles show them asking “Feature?” and “Model?” The image humorously illustrates how people can misunderstand the same terms and the importance of shared definitions.

One of my team mates (an absolute Lord of the Rings (LOTR) overnerd) recently starting to close all meetings with "Merry Christmas", "Happy Easter" and the like.
I asked him a simple question about that.
Dark-mode Slack screenshot of a playful chat. Participant 1: “Actually, I’m a bit disappointed… Why don’t you close meetings with a LOTR quote? 🤔” (followed by a row of fun emojis). Participant 2: “You just shattered all my self pride with that simple question.” (reactions: 🤣×1, 😂×1). Participant 1: “That’s my job as a tester: to smash illusions… Usually about software, but I’m also strong on the soft-skill side.” Participant 2: “i can see that 😄”. One participant’s name is pixelated for privacy.

No #RestBash for @tamarajosten.bsky.social & I after #MotaCon #TestBash. We spend two days in London and enjoyed it a lot.
A little bit of sightseeing tomorrow and then heading home.
Last evening today in a typical pub. 🍻🍎
A cozy pub scene featuring two drinks side by side on a polished wooden counter. On the left, a half pint of clear, golden cider glows warmly under soft indoor lighting. On the right, a perfectly poured pint of Guinness sits proudly in its branded glass, showcasing its deep mahogany body and iconic creamy white head. Both drinks rest neatly on black coasters against a backdrop of a wooden wall with a power outlet, and a window revealing blurred city lights reflecting the calm evening atmosphere.

There was no „Having a beer at a sunny beach“ left on my 2025 bingo card, what a nice surprise! 🤩🍻

Great crowd at yesterday's @ministryoftesting.com Munich meetup! 😀
I had a lof of fun presenting, live coding and answering all the questions! 🤩

Big thanks for organizing and having me!
Sunset-lit Ministry of Testing meetup inside MaibornWolff’s ‘Kraftwerk’ office—industrial loft with exposed ducts and floor-to-ceiling windows. Christian stands as the speaker before a slide titled ‘GitHub Actions in Action: Pick your Power-Up’ with retro game icons. Attendees sit in rows, some in silhouette; lens flares streak across the room, city skyline through blinds, and a tall gradient sign reads ‘WELCOME.’

Next milestone: Half a year of none smoking! 🚭
Some additional kg, but that’s okay.

I’m working on a talk for the @ministryoftesting.com Munich Meetup next month, the title contains „power-up“, so I was thinking about making the slides Super Mario themed.
TIL there’s an AC/DC album called „power up“.
Well, that’s a really hard choice! 🙈🤷‍♂️🤔
