Stuck 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

GitHub 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.

Only 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 #log4shell

I am currently in San Francisco to attend #Github Universe. So far, so good. I like the city.

"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. 💛

As 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/...

I 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

OK, so enough hiatus. I'm back. It's Monday, early morning. Today, something will change. Will keep you posted.

I dreamed of writing a "#Java Logging" book after #Log4shell hit. Today I’m proud to share: @manning.com just launched it in MEAP. Hard to describe what that means—a circle closes. Until Oct 2: 50% off: hubs.la/Q03Jv97v0 #log4j #java #logback #slf4j

Today, 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

I guess you could say I am a power user now. However, some recommendations make my writing worse, not better.

It 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 :)

I 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!

Looks like some contracts were canceled this year. Which means I finally have time to work on my #java training website again 😊👍

This 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.

I 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.

If you don’t know the facts, you’re forced to believe. When you’re forced to think, anyone can claim the truth. And when you can’t tell the truth from lies, fear takes over. Science is the antidote to fear. It’s not always what you want to hear, but it’s the way forward.

For 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.

Finally, I will write for a print magazine again! I just received confirmation that my proposal about #Java logging was accepted. Looking forward to seeing it in the Javapro magazine; it has been a while since I last published for print. :-)

It sounds stupid, but I am slowly beginning to understand how to write sequentially. Took me more than a year of practice. Writing is hard.

Companies: Remote work doesn't work for software development. Open Source: Am I a joke to you? Doesn't your business run on me?

For 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

FYI: We (the JUnit Team) are planning on #JUnit6 with a #Java 17 baseline, hopefully to be released in the Fall of 2025. 😎 github.com/junit-team/j...

For the past weeks, I have been studying #Cicero, among others. His work resonates deeply with me. My writing changed not only because of style but also because I learned to write as a human. No #AI will ever write what a great writer can write as long as it cannot replicate the depths of humanity.

The 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…

I will never understand how a Dockerfile works before I go on vacation, and it will suddenly break when I return. This is not a docker problem; I think the dependency management in Ruby and JS causes the problems.

Populism is a short-term reaction to fear and change. Giving young people access to education and science should reduce fear and explain change as natural progress.

A proper response from a Canadian politician to Trump. Not only content is brilliant, but her way of telling is too. I could not tell if she is working in TV or in politics. https://buff.ly/4jaliaS (video)

Spent 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.

#Raunächte is over. This was an experiment I always wanted to do. Do you have any feedback for me, or does this annoy you? Let me know. I enjoyed it, personally. It's a lot of work, though, if you didn't like these posts, let me know.

In 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.

I made a small Java build tool! With the kids being a bit older, I found some energy again to play with something I had in my head for a few years. This is still very much a POC, but I am happy with the direction it has taken. Have a look and let me know what you think! github.com/raphw/build-...

Life of a self employed: I share my holidays with taxes and other things. Lucky me, I only had to work until 10pm. I know I do it wrong, but many are.

I 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.

December 27 – March: Opening Up | Weihrauch, Juniper Teams thrive on openness. Like your code. Whether it's a pull request or inner reflection, let yourself be vulnerable—better things will emerge. Smoke Weihrauch and/or Juniper to inspire connection. #Raunächte
