If you have a tool that can produce stuff faster than before BUT at lower quality/worse customer experience: when would you use that tool?
Personally, I'd use for prototyping + throwaway (quality unimportant)
Def not for customer-facing stuff... until quality is as good or better vs before
How does #Java Vector API accelerate parallelizable computations?
I explored it in my new article (with an example):
Estimating value of pi (π) using Monte Carlo Simulation and Vector API

I'm usually not that much into rap, but this is very well done 🤩 www.youtube.com/watch?v=zpvd...
In the end it took close to 90 minutes, previously that was below 10 😅 Guess the hamster in their server was taking a diner break 😎
If you haven’t listened to @rdehuyss.bsky.social ’s interview on the Marco Show yet, stop what you’re doing and get the episode: you’re in for a treat!
Ronald is a wonderful human being, smart and funny. He runs a fascinating OSS project @jobrunr.bsky.social and … he ”makes money selling a .jar” 😎
@glycin.bsky.social "Please RickRoll me"
P.I.P.: Certainly 🤩🤣
Getting ready for @glycin.bsky.social at @jugnoord.bsky.social sharing his AI pair programmer P.I.P.
I don't always have time to watch Ted's streams, but it's great to see him following up with a blogpost on what he encountered and learned each episode - such as migrating Spring boot 3.5.x -> 4.0.3 😎

If you were in Coimbra last May, you’ll remember it.
Two days of technical depth. Sharp questions. Packed rooms.
JNation returns to Convento São Francisco on 26–27 May.
A new edition is in the making!
Last year’s highlights below.
#JNation #Java #Coimbra
Let's talk about #Java's checked exceptions - smartly. Not whether we should have them (that ship has sailed) but where the friction comes from and what could be done to reduce it:

📢 AssertJ joined the GitHub Secure Open Source Fund, a program that leveled up security across 67 open source projects.
What changed for us: SHA pinning, immutable releases, incident response plan, and a mindset shift toward security awareness 🔒
The impact? More robust JVM assertions 🚀

Had an extensive conversation with Marco at @jetbrains.com about the future of @graalvm.org, the benefits of ahead-of-time compilation, and whether AI is going to take over compiler development 😉.
So, Antropic released a 42s promo video of Opus 4.6 generating a working C-compiler 🙃
Impressive, but if you're looking for details and some more nuance by the 'conductor', this is a good read: www.anthropic.com/engineering/...
"Now I can show you how to do this on Arch, btw." 🤣

Organise an internal meetup with three great speakers 🤩
Have everyone in the building evicted just after the third session starts 🫤
There's a first time to everything, and at least now we'll have an excuse to organise the next meetup on short term 😅
The JCON shirts are true gems every year - and as a speaker, you'll even get one for free 🤩
Lazily initializing fields in #Java is error-prone and undermines constant-folding. JDK 26 comes with JEP 526, which previews `LazyConstant` - the remedy to this malady.
More details in Inside Java Newscast #106 - join me for the premiere tomorrow morning, 0700 UTC:

This is a @josepaumard.bsky.social appreciation post.
There's a reason I don't use self check-out unless I only have 2-3 things to purchase. If more customers would do that, more people would be hired as cashier again.
Plus waiting in line is a great moment to disconnect/think 👍
What I’m hearing: large open source projects are being absolutely hammered by AI-generated security reports. To the point of not being able to handle them.
Feeling is lots of ppl want an easy way to put a CVE on their CV and collect $$ for bug bounty.
Super bad for maintainers
HTTP/3 support is coming in #Java 26. 👇🏾
