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

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...

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! 😀

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. Check out his 30 years of Java photo compilation here: www.flickr.com/photos/jabbe...

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.

It’s incredible to see the Java community thriving after 30 years! I’m honored to keynote Duke Turns 30 and take a look back at Java’s journey - from its humble beginnings to its impact today. Let’s celebrate together and explore how Java continues to shape our world. www.azul.com/duke-turns-3...

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%!!!

If you'd like to watch my "30 Years of Java: How Did We Get Here" session from @jfokus.se, you can find it on YouTube. www.youtube.com/watch?v=IcTm...

I'm flying from Nashville to Atlanta tomorrow (ready for @devnexus.bsky.social!) It's a 42 minute flight and Delta is offering me a "fantastic" deal to upgrade to First class for only $692 😱. I think I'll pass 😂

Yesterday, when I left Stockholm, the border control agent looked at how many EU stamps I have in my passport (80, as it turns out) and asked if I was keeping track of how long I had stayed. This was a first; now, I must create a spreadsheet in case I get asked again. Just one more Brexit bonus...

30 Years of #Java at @jfokus.se. Really enjoyed myself, and I thinik the audience did too!

I'll be presenting "30 Years of Java: How Did We Get Here" on Wednesday at 2pm at @jfokus.se. Come along and share some (probably a lot) of nostalgia. Here's my collection of JavaOne badges. I think we got a bit carried away with ribbons in 2017 (@sharatchander.bsky.social) 😀

Continuing the #Java memories, here's my collection of Java pins.

Deep Seek v ChatGPT. My son said, "ask them how many r's are in strwaberry?" Deep Seek: 3 in the 3rd, 8th and 9th positions ChatGPT: There is only one "R" in the word strawberry I guess SkyNet won't be running on ChatGPT 😱😂

My 30 Years of #Java talk for @jfokus.se is now ready (although will doubtless get tweaked until just before I present). 75 slides in an hour means I'm going to have to keep up a decent pace!

Ahhh! Apple!!! I connect an external SSD and there is a pop-up to confirm I want to allow it to connect. Which appears for just long enough for my retina to register it, but no chance to click accept. What kind of crappy UI is this? I have now found the setting to disable this 'feature'.

I just saw this on Twitter, and it made me laugh. "Who'd have thought ChatGPT would have lost its job to AI." 😂

As part of my #Java research, I'm using the MKS Korn shell on Windows XP. It has taken me all day to remember ESC \ to complete file names. How many times have I used that in the past? Although I did love ksh, bash is significantly better, IMHO.

Continuing the trip down #Java memory lane... Here's a selection of Dukes I found and a copy of Java Workshop from 1997 (version 2.0 Dev1). I had to set the clock back to 1997 on my VirtualBox Windows XP to make it run! 😂

Essential #Java coffee cup collection (with the Palm Pilot in the background).

I've started work on my "30 Years of Java" talk for @jfokus.se, and it's proving to be a lot of fun. I just showed my son the Java ring and explained it had a computer in it. He did not seem convinced 😀 I've also got my PalmPilot up and running for the KVM and even a Livescribe Pulse smartpen.

How on earth did someone manage to run Doom inside a PDF document? I am impressed!

Help me out. Should it be open-source or open source? Does it really matter? 😀

I think I can say I've adapted to being a Canadian. Here's me last night working the BBQ in the snow. It's -7C, and I didn't even feel the need to wear a jacket!

Phew! Still on vacation in Canada, but I managed to squeak my submissions to @devoxx.uk just in time!

Many thanks to @jetbrains.com for renewing my Java Champion license for IntelliJ for another year.

Achievment unlocked! I just got my work inbox down to zero messages, all ready for the Christmas break. Let's see how long that lasts 😀

I find it funny that when I log in to Apple on my browser, the TFA code is displayed on all my Apple devices, including the Mac I'm logging in from. Doesn't that rather defeat the whole idea of TFA? 🤔

An early Christmas present from OpenAI. github.com/openai/opena...

Does anyone still use Slideshare? I needed to share some slides, so it seemed like a logical choice. Right up until it demands that the title of my presentation has to be a *minimum* of 40 characters. Why? The title, which is quite clear, is "Java Pattern Puzzles", which is only 20 characters...

Today, my Windows 10 machine has popped up a dialog box for Explorer, saying, "Unknown hard error". I never cease to be amazed by this. How can it be unknown? Something caused this, so surely Microsoft could provide a better message...

From time to time, I am asked to review books on Java. I really enjoy this as I always learn something new. Today, it was the realisation that, in JDK 16, instanceof became an overloaded operator. It either works as the type comparison operator or the pattern match operator. 🤔

Am I missing something obvious? Is there a way to bookmark posts on @bsky.app (like there is on that other place)?

I just booted my new @raspberrypi.com 5, which I bought in the Black Friday sales. It tells me I need a 5 Amp power supply (I thought my old RasPi 3A one would be good enough). With great power comes, well, great demands for electrical power 😀

Last night at @bejug.bsky.social was an absolute blast. Combining my patterns session with the puzzler BoF produced an interactive, eductional and fun presentation.

I have decided that @bsky.app is going to be my social media happy place. Hopefully, my timeline will be different to the one served up on Twitter.

It was a beautiful day in Prague yesterday, and Kaleo were outstanding. I would honestly say they were one of the best bands I've seen live.

This weekend, my son and I are heading to Prague to see #Kaleo in concert. Very much looking forward to this. Way down we go!

I'm not always convinced by the alternatives that @officialgrammarly.bsky.social offers me 🤔

It's always fun to see performance comparisons like this. Sure, it is utterly meaningless in a real-world app, but it gives an idea of how different languages *can* perform. benjdd.com/languages/
