🎥 NEW VIDEO on the channel from @asm0dey.site You don’t need to switch frameworks to learn something new. This time on the channel: @quarkus.io , explained for developers who already know Spring and want to broaden their Java framework knowledge. #Java #Quarkus #Learning

1/ I made slidev-polls: self-hosted live audience polling for @sli.dev decks. Drop a PollResults component on a slide; advance to it; audience joins from a phone, votes, results animate live on the slide in your deck's theme. No tab-switching. github.com/asm0dey/slidev-polls

🛫BER -> AMS -> BCL🛬 Let's go! @springio.net I'm coming to you! One of my favourite conferences, BTW, which stably brings me into top-100 viewed tech talks of the year

CyberJAR crossed 100,000 views on YouTube. 🥳 For us, that is more than a number. It means people keep coming back for practical #Java content from @asm0dey.site and @edelveis.dev, and that means a lot. Thank you for watching, sharing, and helping the channel grow: www.youtube.com/@cbrjar

If your MCP tools are getting ignored or misused by models, it’s probably the naming. I put together a skill to help fix your descriptions for better tool-calling. tessl.io/registry/fin... @tessl.io

Greetings from #JavaOne! @asm0dey.site is there this week, meeting the community and taking in everything the event has to offer. 😎

Choose your poison!

👾New on CyberJAR: Spring Developer Roadmap 2026 Being a great Spring developer is not only about knowing the framework, but also about mastery of backend engineering. This roadmap by @asm0dey.site covers the essentials you need to know to stand out: www.youtube.com/watch?v=nuld...

Berlin: @asm0dey.site is hosting Spring User Group Berlin this Thu (Feb 19). K8s Secrets in Spring, the production way (env vars vs files, rotation) + Kotlin for Spring 7 (pros/cons). 18:30 CET. RSVP: www.meetup.com/spring-user-...

Sure did! Sure are :)

Two tools enter. One tool wins. 🥊 Liquibase vs Flyway is going head-to-head at #Devnexus. Join @asm0dey.site & @antonarhipov.bsky.social to explore every detail — then cast your vote for the migration tool you trust in production. devnexus.com/events/the-u... 🎟️ Get tickets devnexus.com

The next #Spring Berlin User Group is coming! 🍃 Hosted at DeutscheBank w/ speakers from DB & @jetbrains.com. Join @maciejwalkowiak.bsky.social and me for a deep dive into all things @spring.io and #Java. Don’t wait, registration is open! Details here:

Day 11 of #AdventOfCode was way easier than the day 10! Because of 2 reasons: 1. I already knew which lib I needed for graph processing 2. A very similar task was solved on day 7 The visualisation is nice tho! asm0dey.github.io/aoc-2025/day...

WOW, the day 10 of #AdventOfCode was CRAZY. I would never solve it without AI. It didn't generate any code for me, but for part 2, I really needed at least an idea of the approach. And even having it, I would not write it myself - had to use a new amazing library: ojalgo www.ojalgo.org

Day 9 of #AdventOfCode was more complex than previous days. I should admit, I had to use jawa.awt Polygon to solve it (and it's the first time I used it in my life!) However, the solution itself is very simple when you know the ALGORITHM

The solution for day 8 of #AdventOfCode is also simple, I would even say straightforward. But I spent an enormous amount of time debugging the first part, where I couldn't get the correct result even for the test input. Visualisation is nice and dynamic tho! asm0dey.github.io/aoc-2025/day...

👾New on CyberJAR: Build RAG System with Spring AI In this video, @asm0dey.site explores the full RAG workflow in #SpringAI: document ingestion with TikaDocumentReader, embedding generation, vector storage, and similarity-based retrieval. www.youtube.com/watch?v=Etnc...

Full sold-out on the joint JUG BB & Spring Berlin at the @jetbrains.com office! And you can participate too at www.youtube.com/live/zZAfnZO...

It seems the last business trip this year starts: going to talk at jug.cy hosted by @a-kogun.bsky.social Catch my of you can at www.meetup.com/jug-cy/event...

This Friday, Nov 21, @asm0dey.site is speaking at JUG.CY in Nicosia. If you’re around, join the meetup at Wrike Cyprus for a deep dive into building better Docker images for Spring apps: www.meetup.com/jug-cy/event...

@jbaru.ch, @asm0dey.site, sending good energy for the talk ahead! Old Java still runs Needs tests, fast speed, and safe design Through runtime it flows #Devoxx #Akka #room7

Still on Java 8 or 11? You’re not alone. Tomorrow at #Devoxx Belgium, @asm0dey.site (#BellSoft) and @jbaru.ch (@TuxCare) show how to make legacy #Java feel better – cleaner code, safer apps, faster runtime, without forced rewrites. 📅 Thu, Oct 9 • 13:50 • Room 7

Thank you! We had to replace Anton with another speaker, but it still will be an amazing talk!

And @jonatan-ivanov.bsky.social! I would even say Jonathan and me :)

It's this time of the year! sdk install java 25-librca

“Microservices will fix it.” Not always. @asm0dey.site explains why most apps run better as modular monoliths with Spring Modulith: clearer structure, safer tests, and less complexity. youtu.be/AkXkEIc8hw0 Curious to hear your view – microservices or monolith?

🍃 Four Approaches to Reducing Java Startup Time: AppCDS, Native Image, Project Leyden, CRaC by @asm0dey.site & @cat-edelveis.bsky.social @ Spring I/O 2025 ▶️ Video: youtu.be/UVFJ0VXWBZo 🔗 Slides: code-with-bellsoft.github.io/java-startup... 🛠️ Repo: github.com/code-with-be... #springio25

Do you really need DTOs everywhere? @asm0dey.site explains how to hide sensitive fields, build role-based views & simplify APIs with Jackson – no extra DTO classes. Full video: youtu.be/m8He5BRmHKo

The #GodotEngine just got a major new supporter... @jetbrains.com - one of the biggest creator of developer software, including Rider, the #gamedev IDE. Excellent news! gamefromscratch.com/jetbrains-sp...

@jbaruch and I are talking about (better) life with legacy in 5 minutes! youtu.be/ccbDPRmvVBM

It's always nice to know something from your personal history. For example, this person died in roughly 1780s. For my 6th-generation grandpa, we know the year of death, but not the date. He died in 1831

No upgrades on the horizon? Still on Java 8 or 11? This webinar is about what you can improve anyway: structure, performance, security. 📅 July 23 | 7:00 PM CEST 🎙 @asm0dey.site & @jbaru.ch bell-sw.com/webinars/jav...

It only took 15 years to make the transition between community and ultimate smoother!

OK, hear me out! Spring AI's MCP Server API is just amazing! But! I'm trying to build a native image of a local-only (studio) MCP server, and I want to build a native image from it. And it builds, without any arcane magic! But doesn't work — the list of tools gives a timeout to my client :(

This video features so many amazing people — @sergialmar.com, @martinelli.ch, @asciidwarf.bsky.social, @ddobrin.bsky.social, @cschuszter.bsky.social, @julientopcu.com — that I don't deserve to be on the cover!

Woah, this is one amazing code generator! I don't like Lombok in general, but Builder here (especially staged builder) in conjunction with records is a-maze-ing! github.com/skinny85/jilt

OK folks, who managed to make Spring AI MCP server in stdio mode work with GraalVM native image (or NIK)?

The first letter I have in my current GMail account is a letter from Trafigura with a home assignment. I deleted all the letters before and many thousands letters after. Why? 🧵 (1/15)

And this is how I know we're doing something useful!

OK, how the hell is it possible that Sora can draw a picture of a glass of wine full to a brim? No other network I'm aware of can't because there are no such photos in internet and they don't conceptualise!

I dunno folks, not sure if I really missed it

Voxxed Days Luxembourg – we're on! @asm0dey.site is speaking today at 14:45 with a dev story that starts with ChatGPT and ends in a full-blown RAG bot built on Spring AI. Don’t miss it!

Zero-days, legacy code, and no time to spare. @asm0dey.site is live at #JRush – sharing how teams handle security fixes under pressure: youtube.com/live/vW6n5ci...

I didn't even realize how much syntactic sugar modern Java contains. Look at me desugaring it and struggling youtu.be/uTQDOXCen0c

You all know falsehoods about names and falsehoods about time: www.kalzumeus.com/2010/06/17/f... gist.github.com/timvisee/fcd... I found a friend of theirs, and it's amazing and made me think a lot: falsehoods about aviation: flightaware.engineering/falsehoods-p...

As I said, I admire and recommend self-hosting And here is one more beautiful post on the topic! www.ssp.sh/blog/self-ho...

Q: Is the Eclipse IDE required to use Eclipse Collections? A: No. Eclipse Collections is a stand-alone Java library and one of many open source projects at the Eclipse Foundation. I was asked again yesterday, and responded w/ the branding section of this blog.👇🙏 donraab.medium.com/there-is-no-...
