🎉 JBang just passed 3 MILLION binary downloads! A 2019 experiment to make Java easier to run — `jbang hello.java` — has quietly become Java infrastructure. ~1,000 downloads/day, 130+ countries, Java 8 → Java . Thank you 🙏 https://www.jbang.dev/learn/somehow-jbang-just-passed-3-million-downloads

So close…

jbang app install jfr-mcp@btraceio Now just tell your agent to add jfr-mcp —stdio as mcp server and you have awesome portable Java performance help. Awesomeness.

Almost at 3 million downloads of JBang! 🎉 Screenshot the counter when it hits it in the next week! Thank you to everyone who uses, contributes to, and shares JBang. You make this happen. www.jbang.dev/usage/downlo...

I watched Project Hail Mary over the weekend. I regret not having watched it in the cinema - its visuals, mood, colors, tone and science based story telling was just Excellent. Highest recommendation from here. image: winterpens.art

"make ponytail review using hunk" is my new agent addiction :) https://github.com/DietrichGebert/ponytail https://github.com/modem-dev/hunk

Does anyone in my network work on or with JFrog Artifactory? We've been hitting bugs that have been open for *years* and appear completely stale. I refuse to believe nobody's looking at these. Would love to talk to someone on the inside before I lose my mind. 😅

Wrote about the migration to Aesh in JBang at https://www.jbang.dev/learn/from-picocli-to-sh-how-porting-jbang-s-cli-made-everything-better/ Yet again we see what impact reflection vs build time processing can have on even the small things!

jhostty running various tamboui demos

Built a full terminal emulator in a single Java file. jhostty — probably the most portable terminal in the world. Splits, tabs, 10 themes, per-pane zoom. Powered by GhosttyFX. jbang jhostty@maxandersen github.com/maxandersen/jhostty

🚀 JBang 0.139 is out! ⚡ picocli → Aesh: 2-5x faster startup 🖥️ Native binaries (early access) 🔍 Smart tab completion for scripts, GAV, GitHub URLs 🔎 New deps search TUI 📦 Multiple JDKs per major version https://github.com/jbangdev/jbang/releases/tag/v0.139.2

Aeshell fixes out and now tamboui…what’s next ? :)

nerd-sniped again...now with a proper video https://github.com/maxandersen/tamboui-draw

Ported termDRAW to Java 26 with Tamboui + JBang 🎨 Terminal-native diagramming app — boxes, lines, elbows, paint, text tools. Braille smooth lines, Nord theme, undo/redo. Run: jbang tambouidraw@maxandersen/tamboui-draw github.com/maxandersen/tamboui-draw https://youtu.be/H-LcVmS-OzY

The moment you notice pi agent using tmux to launch your tamboui app and send key events to validate behaviour beyond just the unit tests. https://media.tenor.com/vlrr3uv6GgIAAAAM/100.gif

You are not your code. Speaking at Red Hat Developer Day in Aarhus about what happens to developer identity when AI writes the code for you? Not a hype talk. Not a doom talk. An honest one. https://maxandersen.github.io/presentations/youarenotyourcode

Made it to the main land to attend and present at Red Hat Developer Day at BankData in Aarhus!

nerdsniped again - tambocam; a webcam viewer for your terminal :) https://github.com/maxandersen/tambocam Because...why not? :)

What are text blocks in a TUI editor called when rendered into 3D ? vtixels ? https://github.com/tamboui/tamboui/pull/348

Announcing Endive, a WebAssembly runtime built natively for the JVM, now a Bytecode Alliance project. Zero native dependencies. One JAR, every OS. Check it out: endive.run bytecodealliance.org/articles/end...

#TamboUI - the first modern Java TUI library. It promises support ranging from low-level terminal drawing to high-level APIs, including components and event handling. Now at v0.3.0, it’s already being adopted by major projects like Maven & Spring. 🔗 Learn more: bit.ly/4fKgoSL #InfoQ #Java

Nice InfoQ article about TamboUI https://www.infoq.com/news/2026/05/tamboui-java-tui/

The recent fixes @staalep.bsky.social been making to get aesh to match picocli features been really fun to do.

Working on picocli to aesh migration the last few weeks for JBang. The startup difference is amazing: 2-17x faster. JVM mode is now amazing but native mode is even faster. lesson learned again and again - reflection is a startup killer; build-time makes all the difference!

What he said! :)

A post about 3D object rendering in a terminal flew by my newsfeed today - couldn't resist and made draft PR for TamboUI https://github.com/tamboui/tamboui/pull/348

One thing I've always used #LLMs for is generating utility scripts. Back in the "ChatGPT is amazing!" days, I used them to help me write bash scripts because I'd always forget the syntax. Now, I use them to generate full-blown scripts, but more often I'm using #Java and #JBang (www.jbang.dev ). #ai

The video of my talk at Devoxx France with @maxandersen.xam.dk about #TamboUI, our Java TUI framework, is online! www.youtube.com/watch?v=lVwp... Time to revisit your assumptions about Java in the terminal!

TamboUI 0.3 is out! Markdown viewer with streaming, unicode and bracketed paste support, even crispier images and more. See https://github.com/tamboui/tamboui/releases/tag/v0.3.0

FYI @mojavelinux.com

Meet lazyslide: Render asciidoc decks, serve them locally, watch for changes, and bootstrap new talks with one command. Built for people who’d rather ship slides than fight tooling. jbang app install lazyslide@maxandersen https://maxandersen.github.io/lazyslide

Yesterday I spoke at Claude Code for Developers in Odense - less than 15 min from my doorstep. Felt good to connect closer to home. Topic was “How AI Coding Agents Actually Worked” and slides you can find here: https://maxandersen.github.io/presentations/how-does-coding-agents-actually-work/

Reminder that we’ll have Meet Quarkus Session at Devoxx France at 17:00 in room 243 I got bricks to share :) https://youtu.be/6zFla1JpKBU

jbank & caucus :)

JVM et terminal, je ne pouvais pas louper @maxandersen.xam.dk et @melix.champeau.me à @devoxx.fr et on parle de TamboUI (Tambouille, juste pour le nom 😍)

What he said! :)

Back hosting on Quarkus Insights - come see Holly, Franz and Eric talk about our recent benchmark efforts! https://www.youtube.com/watch?v=LTS2ppoHacI

So much for preparing for Devoxx. Got a Stream Deck+ yesterday, had an idea, and 5 minutes later a freshly hacked Quarkus + TamboUI app was feeding it live status from the agents running on my laptop. This is either progress or a cry for help.

Ported skills.sh from TypeScript to Java+Quarkus in one AI-assisted session. 196 tests, ~10ms native binary, zero Node.js. https://maxandersen.github.io/jskills/ https://www.linkedin.com/posts/maxrydahlandersen_the-agent-skills-directory-activity-7451209487178297344-4JDT

Friday rant: The amount of mismatch Microsoft 365, Sharepoint and Box can make of a simple share between 2-3 people is amazing. Google Docs is so much better suited for collaboration. I loved using Microsoft Word in the 90ies, but boy have it not adapted to this century

Next week Zineb and I are hosting "Meet with Quarkus". It's my first Devoxx France so looking forward to it and especially since Markus Eisele brought me a few gifts to share :) https://youtu.be/6zFla1JpKBU

Try this in your maven project: mvn eu.maveniverse.maven.plugins:pilot:RELEASE:pilot So Happy to see Tamboui being used to improve developer UX for Java world! Good stuff from @gnodet and @cstamas happening in https://github.com/maveniverse

Much ❤️ for @almiray on his comments on what been missing in Java in latest The Marco Show #jbang #tamboui #picocli #jreleaser https://www.youtube.com/watch?v=Jts62hWkRO8&t=3048s

I ported nanocode, a minimal AI coding agent, from Python to Java. 261 lines, one file, zero frameworks. Just JBang, Jackson, and a loop. Want more try quarkus.ai https://xam.dk/blog/nanocode-coding-agent-in-260-lines-of-java/

Awesome photo of Earth by Artemis from https://www.bbc.com/news/articles/ce8jzr423p9o with caption: "The Earth appears upside down..." No. The Earth is exactly where it has always been. It's your internal map that's keeping your perception locked into an imperfect model of reality.
