Today is quite significant for me personally.
It marks the 30th anniversary of the day I started working at Sun Microsystems.
I try to imagine how I would explain to younger me where I would be in thirty years.
😀

It's been a while since Windows has really annoyed me but something seems to have changed...
Why is there no way to tell Windows that I have a FAT-formatted USB key and I DON'T CARE ABOUT NTFS PROPERTIES NOT BEING COPIED?
Every time I copy a file, I get the pop-up.
Every. Bloody. Time.
😠

I'm stealing this. 😀

I'm very sceptical about so-called Vibe Coding for creating entire enterprise applications using only natural language prompts.

However...

I'm using Claude to generate classes that I'm assembling into a test application, and it is incredible how quickly (and efficiently) I can do this.

Local Variable Type Inference in Java: Friend or Foe? Local variable type inference helps simplify Java code. But in some situations, it can actually make code harder to understand.

Interesting times at @azulsystems.bsky.social

Today marks exactly ten years since I joined Azul.
It's been a lot of fun and lots of Java.
Here's to the next ten years. Maybe!

Yes, slide 48 is not fair, as you can't get the answer from looking at it.
The answer is Unicode character, \u001d, which ia a soft hyphen (slide 49).
This works fine for me in IntelliJ.

Java Modern Puzzlers, a guide to new programming features A selection of puzzles around new Java language features. This focuses on the switch expression, pattern matching and sealed classes (sort of). - Download as a PPTX, PDF or view online for free

If anyone is interested in the slides from my @devoxx.com BoF session on Modern Java Puzzlers, they can be found here:

I'm here at @devoxx.com, and I've worked out that this is the 15th time I've attended the conference.
Join me this afternoon for a fun retrospective on 30 years of Java.
At 1745, I'll be doing a BoF session on Modern Java Puzzlers.

I'm on my way to #Dev2Next via Calgary, where I'll be meeting some customers. Looking forward to meeting lots of Java developers.

That's great for us UNIX officianados, but seriously, not having a way to hide all file extensions is horrible UI design.
Even worse is you *can* do it, but on a file-by-file basis!!!
Additionally, one of the fields in Finder is 'Kind', which indicates the exact type of file it is.

Seriously, what is wrong with the UI designers at Apple?
I want to see NO file extensions.
I go to Finder and deselect "show all file name extensions", which doesn't do what it says, because the extensions are still shown.
That is, unless you manually turn it off for EVERY SINGLE FILE!

I have just arrived in Oslo for JavaZone @javazone.bsky.social.
According to my records, this will be my tenth appearance at this great conference.
Join me tomorrow for two sessions: 30 Years of Java and my Java Patterns Details and Puzzles session.

Currently trying to install some ancient software.
"Ant version: 1.10.12 lower than required: 1.6.5"
Sigh...

That would be great, except...

It doesn't work for me.

The keyboard shortcut does nothing, and as you can see, no coloured dot in the menu.

I'm running Sonoma 14.6 and Notes v4.11

Here's a brilliant example of how Apple have lost their ability to design a decent UI/UX.
Apple Notes.
How is it possible that you can't highlight text?
I mean that is like a *fundamental* requirement for a notes app, and you just can't do it.
🤦

It is said that the two hardest things in Computer Science are cache invalidation and naming things.
I want to add a third: version numbering.
Case in point: Apple is releasing the next version of iOS, which is 26 instead of 19.
Java has also had many, many version numbering schemes. 🤔

Currently watching @starbuxman.joshlong.com present at @jnationconf.bsky.social.
It's been a while since I've seen Josh present, and his level of energy and enthusiasm is just off the scale!
😀

Java 30 Java's 30th Birthday. I thought a few words of context were in order today to go with these pictures… worked for Sun Microsystems from 1993 until 2016 (it became part of Oracle in 2010). I j...

Steve Elliott was my host manager when I joined Sun back in 1996. He and I share an obsession with keeping Java memorabilia; he has way more than I do.

Happy 30th birthday, #Java!

I've been writing code since the age of 12, so 48 years (yes, I really am that old).
In the early days of my career, I wrote C on a Wyse 50 terminal, using vi and make.
Today, I use @intellijidea.com with AI for code completion.
A good metaphor is travelling by horse and cart versus a Lamborghini.

If you're in Bangalore on Saturday, why not join me and others to celebrate Java's 30 years?
www.meetup.com/polyglot-lan...

Starting my journey to Bangalore for The Great International Developer Summit.
I'll be talking about JVM warmup (and how to reduce it) on Tuesday and The Art of Java Patterns on Wednesday.
Looking forward to meeting many Java developers.

Can anybody explain why my MacBook continually drops shared Windows filesystems but never does so for SAMBA shares from my Linux box? 🤨🤦

Java puzzler for the day.
The newarray bytecode takes an argument (atype) to indicate what primitive type the array will store.
atype has defined values from 4 (boolean) to 11 (long).
What are the mysterious atype values of 0, 1, 2 or 3?
🤔

Genuine question here.
Is there a single cyclist in London that stops for red lights?
Literally every single cyclist I see happily pedals through a red light, whether it's a junction or a pedestrian crossing.

Tipping in the U.S. has become ridiculous.
I got an Uber today, which cost $43.65. The three default tips offered were $10, $13 and $15.
That's 23%, 30% or a whopping 34%!!!
