Christian Grobmeier @grobmeier.de · 30/10/2025Stuck in SFO. Lufthansa cancelled the flight after 6 hours waiting. No hotel, no water, shops are closed. Currently 25h on my feet. 7 more until I can sleep in the aircraft. Disappointing 260
Christian Grobmeier @grobmeier.de · 27/10/2025GitHub Day 0. Agentic #AI is everywhere in the US. #opensource can benefit from it, this talk says. But the speakers also say, devs will not be replaced—just accelerated. 160
Christian Grobmeier @grobmeier.de · 24/10/2025I am currently in San Francisco to attend #Github Universe. So far, so good. I like the city. 1100
Christian Grobmeier @grobmeier.de · 27/02/2025I guess you could say I am a power user now. However, some recommendations make my writing worse, not better. 040
Christian Grobmeier @grobmeier.de · 24/02/2025It feels good when something is finished, and I just finished the article for the new Javapro magazine. It's about the history of #Log4j. Proud of it. Needed a lot of chocolate. Not from #Java though, but #Japan :) 281
Christian Grobmeier @grobmeier.de · 31/01/2025This year is the year! After log4shell hit, I started again with #Java and #OpenSource related public talks. I want to take this more seriously and plan to travel through Germany and visit JUGs or conferences. Usually, I travel at my own expense to attend community talks. Feel free to get in touch. 062
Christian Grobmeier @grobmeier.de · 28/01/2025I grew up without books. No stories. No beautiful words. No education. At 16, I started to learn, and my now-wife, at 20, gave me her books. Today, at 46, it still hurts to look back. I am angry. My road was hard, far too hard. No one should have to walk on it. 1100
Christian Grobmeier @grobmeier.de · 26/01/2025For two long years, I studied #writing, and I practiced it too. After all this time, I might not be a better writer, but I have learned that good writers are. While #AI reflects the average of us all, good writers transcend every limit. 160
Christian Grobmeier @grobmeier.de · 20/01/2025For my mental health, I usually refrain from commenting on politics. Today, I feel compelled to break this rule and speak out. In Germany, history revisionists yell their devoid phrases from the chancel, echoed by those who struggle with recent politics and are afraid of the future. 🧵 1/8 221
Christian Grobmeier @grobmeier.de · 17/01/2025The feeling when you made your Rasperry blink the first time in your life… I have to admit, without the VS Codf extension I would have been lost. Step by step… 040
Christian Grobmeier @grobmeier.de · 06/01/2025Spent the past year working with Piotr on #Log4j. This turned into deep dives into #SBOM, VEX, and securing supply chains. In 2025, we’re building a #Maven-based tool to help #Java devs write more secure software. No funding. Let’s talk if your company’s wants to learn more about it or #OpenSource. 062
Christian Grobmeier @grobmeier.de · 31/12/2024In November, I was in Tokyo. I came across these muddy waters with dry, withered plants. They weren’t much to look at—ugly, even. But every year, from this dirt, a lotus grows again. If this year was tough for you, I hope the next brings something new. Have a great 2025. 040
Christian Grobmeier @grobmeier.de · 27/12/2024I gifted myself a new food processor. Turned out, the reason I never got into the smoothie thing was the bad device I had before. This one is a dream, using it two times a day. Next stop: oat milk. 050
Christian Grobmeier @grobmeier.de · 19/12/2024I am getting started with hardware programming. In the pic is a fine dust sensor operated by Rasperry Pico. And no, I have no idea what I am doing. 240
Christian Grobmeier @grobmeier.de · 19/12/2024In Germany, when we do business, we are forced to join groups like the IHK. They never did anything for me, except taking an insane amount of money - and sending me their useless paper. This time, wrapped in plastic. 🤷♂️ 021
Christian Grobmeier @grobmeier.de · 13/12/2024I work a lot, but I reflect just as much. It's not esoteric, but personal practice to review what I’ve done and how to improve. While I’ll have less time to reflect (I'm in London), I’ll make it count. What helps me reflect is ‘smoking out’ my room with incense. #MindfulCoding #Raunächte 100
Christian Grobmeier @grobmeier.de · 12/12/2024Pull request reviews are like group therapy in the best case, like group insanity in the worst. Kindness lets you resolve both cases. December 12 #ZenDevAdvent Image: Unsplash #git #pullrequests #programming 072
Christian Grobmeier @grobmeier.de · 06/12/2024No, AI can't take this away. You must understand your code. I followed the internet's wisdom: everyone uses Alpine. Then, an error struck. AI shrugged. Debian-based #Linux would’ve been simpler. Don't outsource curiosity—practice it. Asking is often harder than answering! #docker #learning 140
Christian Grobmeier @grobmeier.de · 05/12/2024A sad trend on my website... You get this when you are not writing anything for one year. Working on @log4j.bsky.social kept me more busy than expected. Time to reverse it and patch my websites... Graphics from Plausible. 140
Christian Grobmeier @grobmeier.de · 03/12/2024All code is impermanent. A function you wrote yesterday might be irrelevant tomorrow. December 1. #ZenDevAdvent 050
Christian Grobmeier @grobmeier.de · 22/11/2024Recently, I talked about #opensource and #java in the awesome #japan user group. There were so many great people! I was there with my @tuxedocomputers laptop, and #linux worked very well! 061
Christian Grobmeier @grobmeier.de · 30/10/2024I love my #opensource and the fact that I can install GnuCash using Brew on my Mac. However, I can imagine how some applications could be much more successful if the UI were better. And yes, I know, I should submit a patch instead of complaining :-) 010
Christian Grobmeier @grobmeier.de · 16/10/2024I think #opensource can be exhausting at times. We should be mindful of how we treat each other and communicate. If we want an "open source community," we should build it with empathy and respect at its core. #mindful #empathy #communication #community Image: DALL-E 010
Christian Grobmeier @grobmeier.de · 07/03/2024Lately, I've been putting much effort into the #log4j website. The changes are not just cosmetic; they're about making the site more useful, accessible, and informative for everyone. Stay tuned for the big reveal – can't wait for you all to see what we've been working on! #java #opensource 000
