Christian Grobmeier @grobmeier.de · 21/09/2026the sad thing is i don't feel to urge to talk to colleagues b/c i talk to ai so much these days luckily my wife makes sure i come out from the basement from time to time 140
Christian Grobmeier @grobmeier.de · 13/09/2026After a long time, I have submitted a talk for a conference again. Travelling and speaking isn't trivial for me. But I realised I probably need to do it again. And want it, too. Back into the saddle! Hopefully they accept the talk, and I'll see some of you there. #speaking #conferences #java 020
Christian Grobmeier @grobmeier.de · 20/06/2026Just submitted my first mobile apps to review in years. The Apple experience is still better. But they charge 100€, which is ridiculous. Anyway, my pet project timeandbill.de will have its mobile apps back soon. #ios #android #productivitytimeandbill.deArbeitszeiterfassung - online, einfach, klar.Erfassen Sie Ihre Arbeitszeit im Browser oder mobil.

Christian Grobmeier @grobmeier.de · 02/06/2026I hate Slack. It’s a mess. Mails are much better. I know how old this makes me sound. 030
Christian Grobmeier @grobmeier.de · 22/05/2026I will never understand why people prefer Claude Code over Codex. Codex never “made up version numbers.” And it never told me to reverse-engineer anything, instead of using the ready-to-use Docker containers. 040
Christian Grobmeier @grobmeier.de · 13/05/2026Audio books read by people—I fully agree. Still I am addicted to the smell of paper (and I have some space left) 020
Christian Grobmeier @grobmeier.de · 13/05/2026I started buying physical books again last year. Nobody can take them away from me. Unless they send the firemen from Fahrenheit 451. 250

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 · 30/10/2025Oh no I missed your post! I was there — would have loved to meet you 120
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 · 25/10/2025Only a few days ago, I joined Abby and Felix Reda on the Github Podcast—to talk about funding in #opensource that we have received from @sovereign.tech podcasts.apple.com/de/podcast/f... #java #log4j #log4shellpodcasts.apple.comFrom Log4Shell to the Sovereign Tech Fund: Lessons in Open Source SustainabilityPodcast-Folge · The GitHub Podcast · 21.10.2025 · 31 Min. 092

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
Reposted by Christian GrobmeierStefano Cordio @scordio.github.io · 21/10/2025"Nobody stops in to check on you. They check on the project. There’s also nobody standing up and saying, ‘hey, thank you for the good work you’re doing to remediate this issue.’" The harsh truth: maintainers give their spare time, yet positive feedback is rare. Appreciate who is behind the code. 💛 0104
Reposted by Christian GrobmeierMarc Philipp @marcphilipp.de · 21/10/2025As a fellow maintainer of an open source project, this is an intense and somewhat scary read. Thanks to @grobmeier.de for being so open to talk about what he experienced and @github.com for initiating their Secure Open Source Fund! github.blog/open-source/...github.blogInside the breach that broke the internet: The untold story of Log4ShellLog4Shell proved that open source security isn't guaranteed and isn’t just a code problem. 0126
Christian Grobmeier @grobmeier.de · 20/10/2025I never imagined GitHub would ask me to speak about #Log4Shell. But it happened. @github.com asked me to share the story as I lived it, for the benefit of users of #opensource. How could I say no? I hope it helps build a more secure future. No more Log4Shell. #java 1309
Christian Grobmeier @grobmeier.de · 20/10/2025OK, so enough hiatus. I'm back. It's Monday, early morning. Today, something will change. Will keep you posted. 040
Christian Grobmeier @grobmeier.de · 19/09/2025You are officially on my awesome list now :) Thank you! 010
Christian Grobmeier @grobmeier.de · 18/09/2025I dreamed of writing a "#Java Logging" book after #Log4shell hit. Today I’m proud to share: @manning.com just launched it in MEAP.

Christian Grobmeier @grobmeier.de · 17/03/2025Without your patience and guidance, none of this would have been possible. You are one of the most important mentors in my life, and I’m deeply grateful for everything you’ve done for me. I know who I was and how much your support helped me grow. Not only as a developer but as a human. 020
Christian Grobmeier @grobmeier.de · 17/03/2025Today, I was awarded the title of Java Champion! It’s a huge honor, and I’m grateful for everyone I’ve met in the Java universe, especially those who taught me how to code. I’m feeling happy and a little proud. 😊 #java #programming 4445
Christian Grobmeier @grobmeier.de · 17/03/2025Wow, thanks, Andres, for the welcome and the update to the repo 110
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 · 24/02/2025You are right but in this case it is Matcha- next level chocolate! 010
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 · 17/02/2025I have been sick all of 2025, but I am getting my medicine today. I am starting new #Java training. These always lift my mood! I'm looking forward to it! 0111
Christian Grobmeier @grobmeier.de · 08/02/2025Looks like some contracts were canceled this year. Which means I finally have time to work on my #java training website again 😊👍 051
