I will never not love the GraalVM logo.
I mean, it's good that google maps recognises swimming, but it's perhaps overoptimistics about the limits of human physiology if it suggests doing it across the Atlantic. 🤣

This reminds me about a walking route from Germany to NYC, USA I tried for fun some years ago. But back then Google listed „swim xxxx kilometers through the Atlantic ocean“ which surprised me in a positive way (that it recognized swimming).

Great talk by @hollycummins.com at Lindholmen developer day. As a data person and as someone who used to work with healthcare this resonated a lot: "don't make human tell computer things the computer already knows". It is so key but so often neglected in practice (&definitely a thief of joy) #databs
Yes, I worked that out after staring at the directions in puzzlement for a while. 😅

With hindsight, there's even a little boat icon on the map, but of course I didn't see that because I thought it was just a walking route.
I mean, it's flattering that Google thinks I can walk on water, but ...
This looks more like a swimming route than a walking route, Google.
... and apparently our streaming provider uses AWS. :)

So no Quarkus Insights today. Sorry, everyone!
⏰ Starting soon! Join us for Quarkus Insights Ep. #223 as Ben Evans @[email protected] discusses the evolution of managed execution in the JVM, its shifting role in the cloud, and innovations like build-time optimization and constrained dynamism.

Big hugs to everyone whose status page origin server is hosted on AWS and just pushes updates to a CDN cache.
And with the benefit of hindsight, investing a lot of time in a Halloween-themed talk did *not* have a good ROI, because I've had exactly one opportunity to give it.

Turns out the demand for Halloween-themed talks about microservices best practices is pretty limited.
Why yes, I do perhaps spend too much time focussing on less-important details of my talks, why do you ask?
As it's Friday, and coming up to halloween, please enjoy my favourite-ever slide deck: hollycummins.com/blood-curdli...

The PDF doesn't capture how I animated the bat wings to flap on the containers, or how I used a greenscreen and and bat cutouts to make it look like bats were hovering over me.

I usually do 5k, but I sometimes do inadvertent-10ks when I get lost in foreign cities. When it's not a choice, there's no mental barrier, and the distance is surprisingly easy. :)

As others have said, the main problem is that it takes a long time.
I don't often donate to Wikipedia, but @molly.wiki's coverage of the current attacks on it has prompted me to pause-and-plunk-up.
It's 2025, and sharing a large file in a work context is still a significant headache. Shouldn't we have ... done better than this?
Darn. I should have worn my "assume all women are technical and can breathe fire" t-shirt.
I didn't have a chance to show this (generated in 13ms with a quarkus + picocli) in my #Devoxx talk:
It's even funnier on a smaller model:
I just tried to reproduce @janelleshane.com's brilliant "make an LLM apologise for suggesting a giraffe as CEO" experiment. It 100% worked on Ollama.

Which is bad, because when I read it I did an involuntary shriek of laughter, and woke a sleeping puppy, and now I won't be able to do more work.
As if you didn't have enough reasons to dislike commuting ... 😔
InfoQ have published "The Efficiency Paradox," complete with transcript.
Apparently I said things like:
- "Am I optimizing for the right thing, or should I maybe be just a little bit more jellyfish?"
- "If you do the same experiment to your stool, it's much less cruel"

There's no sense crying over spilled milk, but spilled coffee?

That's *definitely* worth crying over.
