For the first time in my life, I'm changing the company I work for. @RedHat -> @IBM. I think this is the best thing that could happen for my career and for @QuarkusIO, which I want to succeed.

We are standing strong, continuing our mission.

Transformation complete!

So, this is what created the other day:

redshift -l $(curl ip-api.com/json\?fields\=lat,lon | jq '. | "\(.lat):\(.lon)"' | sed -e 's/^"//' -e 's/"$//') -t 5600:1000

Your eyes and your sleep can thank me later ;)

@gnahraf.bsky.social Actually, it might be only your Maven version. Quarkus needs at least Maven 3.8.6+. In the book, we recommend Maven 3.9.8+. I am able to reproduce this error on Maven <= 3.6.3.

Sorry to hear that. That shouldn't be the case. Do you mind pinging me on quarkusio.zulipchat.com? I will be happy to help you getting it running.

No problem. Everything is doable, and if you show us your use case, we can always add or change some functionality if we see it makes sense in some scenarios.

Hey @tomvanwemmel.bsky.social, this is a decision made by the Kafka integrators in Quarkus. But you can opt out if you need - quarkus.io/guides/kafka.... Would that work for you?

LLMs are probably the worst thing that ever happened to conference abstracts. What is the point of writing a short article for the abstract? We can often see the LLMs' patterns. And I personally reject such proposals.

Use it LM to verify/correct, not write everything.
