Last year was tough.
This year continues like that.

Java Logging - Christian Grobmeier Logging is a must-know skill for Java developers. Logging is the art of making things visible—and when your codebase crashes at 5PM Friday you’ll want all the data you can get about your application!...

My book #Java Logging is the deal of the day!

If you consider it, today is a good day!

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

Oh no I missed your post! I was there — would have loved to meet you

I already voted 1x before I came here…

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

#java #log4j #log4shell

It’s omnipresent, but didn’t see anything related to it (thankfully)

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. 💛

Inside the breach that broke the internet: The untold story of Log4Shell Log4Shell proved that open source security isn't guaranteed and isn’t just a code problem.

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!

Thank you! It means a lot to hear this

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.

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

You are officially on my awesome list now :) Thank you!

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.

Thank you Mark :-)

Without 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.

Thank you very much :)

Thanks Eberhard :)

Thanks Régina :-)

Thanks Gerrit!

Will do :-)

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. 😊
