🟨 SPEAKER DETECTED: Alexander Chatzizacharias @glycin.bsky.social Returns to Jfokus with an RTS game built around Git. Branches become timelines, history enables time travel and merge conflicts can happen between buildings. “Conquest, time travel and explosions using Git” jfokus.se #Jfokus

Hey @devoxx.com #devoxx, tommorow at 13:50 I'll be nerding out about something you use everyday, Git! m.devoxx.com/events/dvbe26/… If you are in the market for a fun, lighthearted, and slightly informational talk, then come say hi!

How cool! You can use @samaaron.bsky.social Sonic Pi together with @intellijidea.com internal APIs to get adaptive music while you code. The music then reacts to how dangerous the method you're editing is. No danger? Cool, calm and collected music. A lot of danger? Pure chaos and stress!

Everyone talks about vector databases. Few people can explain them. @glycin.bsky.social delivers a fun, absurd, and surprisingly practical introduction to vectors, embeddings, similarity search, and the tech powering modern AI apps. Watch: youtu.be/qpUUEXq4xBU?...

AI pair programmers become a lot more interesting once personality enters the equation. Alexander Chatzizacharias is now exploring playful AI workflows, local models and RAG-based pair programming systems. #JNation #AI #Java #RAG #Coimbra @glycin.bsky.social

Made a cool smooth caret trail for intellij. Feel the speed! plugins.jetbrains.com/plugin/31756...

Getting ready for @glycin.bsky.social at @jugnoord.bsky.social sharing his AI pair programmer P.I.P.

Next week is @jfokus.se in Stockholm. P.I.P is all ready for Ragnarök! And I'm just happy to be part of this amazing conference again! See you there?!

I had a lot of fun working on this, thanks for reaching out @jetbrains.com !! The trailer looks amazing :D

25 years ago, the first-ever JetBrains product was released: IntelliJ IDEA 1.0. To celebrate the occasion, the team invites you to a party with Runzo, our special guest, featuring a game by @glycin.bsky.social, interactive postcards, and exclusive giveaways. https://jb.gg/IJ25

I turned a gaming handheld into a coding workstation. 🤯 ❌ No Keyboard ❌ No Mouse ✅ Just @intellijidea.com, @kotlinlang.org Notebooks, and AI Watch me build a Pong game from scratch using only a gamepad and voice-to-text: www.youtube.com/watch?v=I6wY...

We have the @devoxx.com fish, but what about the Devoxx grinch? Amazing pic again @ddoutsiopoulos.bsky.social :)

I've been working on some content for a possible new talk for hopefully @devoxx.com and/or #JFall this fall season. Always wanted a sarcastic, unhelpful pair programmer that puts me in my place when I ask silly things 🥲 What do you think? Would you let this little one blow up stuff in your code?

There was a "History of Spring" game made by VMWare a couple of years ago where you could learn about the history of the framework in a playful way. Unfortunately I can't seem to find it anywhere 😕. Does anyone here know if it's still online somewhere? A simple Google search doesn't help me much :(

Just arrived in Kraków for @geecon.bsky.social and got some lucky charms for my session tommorow 🤘🪄

The **redacted** Club @ @devoxx.uk IYKYK @glycin.bsky.social @thomasvitale.com @bantera13.bsky.social @alina-yurenko.bsky.social @maritvandijk.bsky.social

Accurate depiction of my excitement when I'm at a devoxx/voxxed event and I find out @ddoutsiopoulos.bsky.social is taking photos. Picture by aforementioned, which slaps, as they always do 🤘

Thrilled to be back in London for @devoxx.uk! Though it seems some of the orcs in the village aren’t as keen on traveling 🤔… while others are eyeing big trade opportunities between Mordor and the UK 😅. Either way, I can’t wait!! Devoxx UK is always an absolute blast!

Just got in Zürich for @voxxedzurich.bsky.social and made sure to immediately get a good luck charm for tommorow 🤞🪄. What an amazing city, they sell magic cards in the Central station!

What you’ll find at Devoxx UK: 3 days packed with developer content 130+ expert speakers from around the world 140+ sessions Hands-on labs Networking opportunities Evening socials And more 👀 7-9 May | buff.ly/4D1w8hc

Looks like mentioning Sabaton, Hammerfall and other swedish metal bands helped :D Thanks @jfokus.se , it was an amazing conference (with an amazing opening!) 💥🤘

🏆 And the #1 Top Rated Talk at #Jfokus 2025 is… 🎮 Alexander Chatzizacharias @glycin.bsky.social "Let’s use IntelliJ as a game engine, just because we can" 😁 What happens when you turn #IntelliJ IDEA into a #game engine? Absolute chaos and a lot of fun! Don’t miss this one! 🎥 buff.ly/1POFxkx

🧐 Ever wondered what vector databases actually do? Spoiler: They store vectors (shocking, right?). But they’re also game-changers for AI, search & natural language interfaces! Join @glycin.bsky.social at #YOW25 for a fun intro to Vector Databases—because data storage should never be boring.

Exploding some bugs off of Redis OM Spring database. Can you approve the PR, @bsbodden.bsky.social? 😅

This is an Intellij plugin built by @glycin.bsky.social and showcased in his talk where he uses Intellij as a game engine to recreate games such as Sonic, Asteroid, and Pong using his codebase. Check it out: www.youtube.com/watch?v=TSlY...

I've been playing with the idea of adding a radial menu in @intellijidea.com. What do people here think, yay or nay? And if yay, what kinda shortcuts would you like to see in it?

Hey @jfokus.se . If for some reason u want to look at the code of how I used intellij as a game engine, you can find it here github.com/glycin/intel... Have fun!

The @jfokus.se opening is right up my alley 🤘

Some people asked me where the retro explosion sounds were in the Code exploder plugin. After some initial shame of not thinking about that myself, I updated the plugin with glorious 16-bit sounds. 💣💥💣 plugins.jetbrains.com/plugin/26424...

People really seemed to enjoy the exploding code minigame from my @intellijidea.com as a game engine talk, so I figured I should release it as a plugin. You can download it here 💥💣: plugins.jetbrains.com/plugin/26424... Have fun! And if you find any bugs or have feature requests, let me know!!!

Yesterday we had the first Utrecht JUG meetup in 2025 at the new adesso Netherlands office in Utrecht. With over 60 developers, good food, excellent taks by @glycin.bsky.social and @brianvermeer.nl followed by drinks at the bar, it was a great evening.

A couple of weeks ago Nanowar of Steel released an amazing metal song, HalloWorld.java, and I just had to turn it into a plugin. You can download it here: plugins.jetbrains.com/plugin/26169... It plays sound snippets of the song when certain keys are pressed. A preview for ya'll (fire not included)

🎉 Support your local #JUG! Last week at @amsterdamjug.bsky.social, hosted by @jetbrains.com, we heard great talks on #testing, #IntelliJ, #SpringModulith and highlighted Voxxed Days Amsterdam 🚀 Next: @rotterdamjug.bsky.social on Nov 26 - #HTMX & #Hazelcast talks. Don’t miss it! 👉 bit.ly/4fDPMzX
