Didn't plan it this way, but nothing much scarier than talking about getting a job in tech these days 😱

Check out my full convo with @nerdy.dev about his recent experience looking for a new job:

In about three years the entire university pivot to AI curricula and schools and programs is going to be so deeply embarrassing. We will all pretend it never happened and I will be standing there, looking at people with a mirror in my eyes. This is all so embarrassing.

2025 Update of my ebook 'Getting Started with Java on the Raspberry Pi' 2025 is an important year as Java 25 got released, a version which will be supported for many more years. On top of that, the Pi4J library will soon be …

After doing #Java #Swing, #JavaFX and #SwiftUI for years I came to the conclusion that we might have a lack of developers that understand how to create #graphics in 2D. It is so easy and even if #Swing is a bit older it is absolutely great for doing nice graphical things…just my 0.02€ 🤷🏼‍♂️😁

Groovy Goodness: Use Range With subList Method A blog about Groovy, Java, Clojure, Asciidoctor, Gradle and other cool developer subjects.

I considered writing a long carefully constructed argument laying out the harms and limitations of AI, but instead I wrote about being a hater. Only humans can be haters.

JCrete 2025 I tried to figure out how many editions of JCrete I have attended. Let's just say that it's been quite a few, and I enjoy is just as much every time I return. The community at JCrete is just incredible, the food is awesome. The only thing to wish for is that time wouldn't go so fast. From the informal gathering on Sunday night, the four days just blow past you in an incredible flow of impressions and good moments.

I finally got around to write a small writeup of JCrete 2025

Personally, I haven't seen web AI boosters do anything *except* cede this tech to others, and go with the chatbot flow. I'm refusing to cede my work to software that I've only seen used to lower standards & threaten jobs. If I see some other use, without all the harms, I'll get on board with *that*.

Last week I’ve been at JCrete, an unconference. ☀️🌊 It’s completely different from a conference, but at least as insightful (and fun!).

I’ve met amazing people, had interesting conversations and enjoyed the Cretan hospitality. ❤️ For an impression, watch the aftermovie!

Is #JCrete all fun and games? You betcha! Look at all the topics we covered in 4 days, with ideas for hacking in the 5th day

#JCrete was amazing as always. It was so good to be back on Crete. It felt like coming home ❤️

My kids liked it very much as well. They will miss the daily swimming. But now the want to go to the playground at home immediately 🙂

We are lucky to have very patient kids. Travel time was long.

This is the single best piece I've read on "replacing coders with AI," it fully dispells the myth from the perspective of a software engineer and does so in a calm, reasonable way.

Overheard (OH):

- #GenAI is a force multiplier
- Sorry, did you say "force", or "fools" ?
