My advice to junior developers wondering if they should write code: yes, please do!

Write code, write failing tests, use whatever code assist tools you want to experiment, but most of all: learn! Make sure to understand every single line you write. When you fix an issue, understand why it failed, and why it works with your fix.

A growth in understanding is an incredible valuable asset.

I don't care at all how "good" devs are with "prompts". I want them to understand what they do.

I've spent most of today (and the past few days) on JavaFX 17/21/25 LTS. It's a lot of work, but almost a pleasure because the tools/procedures are so clear. Skara is extremely helpful with backports. And it's deterministic.
JavaFX is very well maintained.

Often, the real problem in software development seems to me comparable to fixing a system with 5 equations and 6 unknowns, or 6 equations and 5 unknowns.
Once you have an equal amount of independent equations and unknowns, consider it done (writing the code is not the problem).

@cupofcode @johanvos Thanks. There is ongoing work for a new release (update to latest OpenJDK) and fixing some of the outstanding issues. Let me know if you need anything..

I love the title!
Great slide content as well (e.g. "writing code was never the bottleneck")

Years ago, I created RedFX, a Quantum Computer simulator in #Java (https://github.com/redfx-quantum/strange) and I wrote a book about QC (with Java) (https://www.manning.com/books/quantum-computing-in-action?a_aid=quantumjava&a_bid=e5166ab9) . My main goal was to understand QC, and writing (code/book) helped a lot.
Now I want to move forward, and do more useful things with Strange.
I want to leverage the very latest #OpenJDK features, make it much faster and have a better API.
And I want to experiment with more qc algorithms.

I see lots of initiatives educating children, older people, and less educated groups about phishing, deepfakes, crypto fraud, malicious content on social media etc.
While often done with the best intentions, I believe it is the wrong approach. I think we should rather fix the crap we created, and prevent even more crap from being created.

Most recent Quantum Computing headlines focus on "breaking encryption" (negative framing). I wish there was more attention for the positive things QC can do, e.g. in drug discovery, using VQE.
