1 down, 1 still to go #Devoxx #speaking

Thanks, everyone, for joining early Thursday morning to learn about speeding up your @maven.apache.org builds. Remember: there is no silver bullet. Apply common engineering practice: measure, analyse, improve.

Slides to follow soon!

Yay for more perspectives!

One doesn't simply attend (or speak) @devoxx.com without posting this picture

Yes, super annoying. At least I got one step further - I now know *why* the domain was deactivated. Now I need to restore it, but it requires the cooperation of the domain name registrar.

I wish I knew! Last Friday, it was made inactive as a result of an "accuracy verification procedure". I'm trying to figure out what that means, how I could've prevented it and how I can restore my domain, but haven't heard yet.

This also affects my personal website & blog. As of this weekend, please refer to mthmulders.nl.

There’s no magic 8-ball behind Generative AI. It’s transformer architecture. It can do lots of things, but intelligent or sentient it is not.

I'm not saying it like it's a good thing, more of an observation. One that increasingly annoys me.

If you're trying to reach me over email and getting delivery failures, thank Italian bureaucracy. They've decided to cancel my domain name. Reach out in DM for alternative means of getting into touch.

For most conferences, the audience *is* paying already. So why tell them ads?

#ThrowbackThursday Can't believe it's already been two weeks since I was on stage with @bmarwell.de at @javazone.bsky.social. We've discussed a structural approach to speeding up your #Maven builds. Missed it? See vimeo.com/1115842570.

Thanks to @maritvandijk.bsky.social for capturing the moment!

Ever wondered what a dependency update brings in? Use latest Toolbox to figure out.

"Spezi" - now that's a name I haven't heard in a little while!

Okay, in over twenty-five years, probably.

Okay, now I feel old.

Used an app, pressed the "Delete my profile" button afterwards. One day later, I got an "Undelivered Mail Returned to Sender". Their system sent an email internally in name of my email address, but it was rejected due to my own DKIM policies...

This one made my father laugh - as the proverbial farmer with a toothache.

Sigh. Some websites still do not allow + signs in email addresses when signing up.

Reason enough to have my article from 2013 translated into English. Only slight updates, captures the situation of 2005-2013, mostly.
