I'm super excited to announce skillsjars.com - Agent Skills that are versioned, security scanned, and available in your package manager (via Maven Central). Details on what it is and how to use it: www.youtube.com/watch?v=eTh1...

#GOTOpodcast: Effect Oriented Programming W/ Bill Frasure, @bruceeckel.bsky.social, @jamesward.com & @andrewhl.bsky.social What if side effects weren’t something you “handle”… but something you model? Full episode out now 🎧 gotopia.tech/podcast

Created my first Agent Skill where I tried to distill my principles for "good code" Check out the "Zen of James" Skill and let me know what I'm missing: github.com/jamesward/sk...

💥 Build, deploy & scale AI agents! Join @jamesward.com & @starbuxman.joshlong.com at #Devnexus for a full-day, hands-on workshop using Spring AI, MCP, Java, & Amazon Bedrock. devnexus.com/events/hands... Learn RAG, chat memory, & multi-agent systems — all in one session. 🎟️ Tickets- devnexus.com

What most devs get wrong about MCP is thinking that it is primarily for AI code assistants. MCP is primarily useful as an enterprise integration protocol.

If you're interested in learning all about MCP, check out the Deep Dive talk that Maximilian Schellhorn and I did this year at Devoxx: www.youtube.com/watch?v=EgKs...

This week @starbuxman.joshlong.com and I made two videos on building AI Agents with the latest milestone of Spring AI (Java or Kotlin) and Embabel, using Amazon Bedrock for inference: www.youtube.com/watch?v=hmEV... www.youtube.com/watch?v=kpeY...

Structured Concurrency by @jamesward.com: Better cancellation & error handling in concurrent code. Covers Java/Kotlin/Scala approaches. Makes fan-out/fan-in easier! youtu.be/XOSR0Asq4h0?...

There has been a huge gap between the world of AI and enterprises' needs. In episode #112 of Happy Path Programming, @bruceeckel.bsky.social and I chat with Rod Johnson about his Embabel Agent Framework and how it helps improve reliability, cost, and other 'ilities when building agents.

Learn to keep your apps platform-agnostic, scale efficiently, and optimize deployment using Spring and Testcontainers in @jamesward.com ’s and @mmeckes.bsky.social ’s Devoxx UK 2025 talk "Write Once, Deploy Everywhere: From Containers to Serverless." Watch here - buff.ly/iIlffzZ

Discover how #PklLang is redefining #InfrastructureAsCode! Unlike complex #YAML, Pkl uses schemas & constraints for robust configuration management, catching errors early and providing clear feedback. 🎥 Watch the video by Dan Chao (Software Engineer, Apple): bit.ly/43ptkpm #Kubernetes #IaC

The Spring AI 1.0 release is a total game changer for millions of developers, enabling them to easily integrate AI & MCP into their Java & Kotlin systems! Check out my blog about why this release is so monumental: community.aws/content/2xLk...

Here is the recording of the "Write Once, Deploy Everywhere: From Containers to Serverless" presentation that @mmeckes.bsky.social and I did at @devoxx.uk www.youtube.com/watch?v=8kgN...

This could go badly, but I've deployed a public MCP server for testing purposes. Built with Spring AI & Kotlin. Try it out: mcp-test.jamesward.com Code: github.com/jamesward/he...

Of course you can build a multi-turn MCP-based Agent on top of Amazon Bedrock Converse and the MCP Java SDK, just with a lot more code than abstractions (Spring AI, Quarkus, Langchain4j, etc). Here's the code: github.com/aws-samples/...

Them: "You can build a multi-turn AI Agent connected to MCP servers in only 50 lines of code" Spring AI: Hold my beer, now watch this:

MCP & Wasm are like peanut butter and jelly. In episode 111 of @happypathprogramming.com, we take some bites into the best AI sandwich ever made with @nilslice.bsky.social: creators.spotify.com/pod/show/hap...

Just finished upgrading some AWS + Spring AI + MCP samples from Spring AI M6 to the new M7. Pretty straightforward but if you need a reference, check out the samples: github.com/aws-samples/...

Had a great chat with Justin Reock from @getdx.bsky.social about developer productivity on Episode 110 of @happypathprogramming.com: creators.spotify.com/pod/show/hap...

I'm primarily a back-end developer and I've struggled to understand how to bring AI into my systems. Luckily I was able to sit down with @starbuxman.joshlong.com and learn about how Spring AI makes this all super easy, including integration with MCP servers and RAG with vector data.

The amazon-q-cli package is now in Nix unstable!

📣 Join us LIVE this Monday for Spring Office Hours S4E9! We're excited to welcome @jamesward.com, Principal Developer Advocate at AWS, to discuss running MCP-Based Agents on AWS with Spring AI. Learn how to build AI applications using MCP and Nova. 🔴 Watch: www.youtube.com/watch?v=U5JD...

Thanks Christian and other Spring AI devs for making it so easy to work with Amazon Bedrock & MCP! Here is the corresponding video that @starbuxman.joshlong.com and I created: www.youtube.com/watch?v=Y291... And the code: github.com/aws-samples/...

🚀 The MCP Java SDK core module provides default STDIO & SSE client/server transports - no external web frameworks needed! Build MCP clients/servers in plain Java with both Async (Reactor) & Sync APIs. Spring support is optional. 🔗 Minimal deps: central.sonatype.com/artifact/io....

Has anyone made it so I can just use assertTrue in Java yet? (with good failure details like kotlin-power-assert / ZIO Test)

Can someone please make a CarPlay app so I can vibe code while driving??

Developers: what is your view of AWS?

In episode 109 of @happypathprogramming.com we dove into AI models, LLMs, and MCP with Lize Raes: creators.spotify.com/pod/show/hap...

httptap is one of the most useful programming tools I’ve been using lately github.com/monasticacad...

Here's a quick article to provide an update on AWS Documentation progress -- sharing details about recent content refactoring, website updates, new content types, and a peek at how we're leveraging AI. I'll follow up soon with a similar update about the SDKs and CLI! 😎 aws.amazon.com/blogs/aws-in...

I don't have much AI developer apocalyptic gloom, but here is one thing I'm pretty sure about... Once the AI code assistants figure out how to interact with type systems and compilers (maybe LSP tools), dynamically typed languages are toast.

Fun story... The fans on my Intel laptop have been spinning like crazy for maybe years. I assumed it was normal. Then a week ago I noticed my keyboard was bulging up. Opened it up. Battery totally bulged. Replaced the battery. Fans now spin a lot less. I think airflow and fans were constricted.

Just used JDBC for the first time in 13 years. Ask me anything.

I am looking for feedback from companies/organizations that are using #Spring + #Kotlin at significant scale (deployed on production). If that's the case, could you please drop a message here or send me a DM if you prefer to keep that private?

Updated my Spring + Testcontainers + Reactive Postgres sample to all the latest things. My favorite part is the app auto-restarts with Spring DevTools, but the Postgres Testcontainer doesn't. Loving the dev flow! github.com/jamesward/sp...

Super excited to be presenting at @devnexus.bsky.social on March 5! - Write Once, Deploy Everywhere: From Containers to Serverless - If you haven't registered yet, use code SPEAK40 for 40% off! reg.connectevents.io/ConnectEvent...

Here’s your periodic reminder that the mutable builder pattern is gross.

In the past week I've written TypeScript, Python, Kotlin, Pkl, and Bash. With all I've used an AI code assistant to help. But even factoring out my experience with each, the AI help is incongruent. Can you guess why?

The state of Node on Windows...

Episode 108 is out! @bruceeckel.bsky.social and @jamesward.com chat about the Winter Tech Forum (March 3-7 in Crested Butte, Colorado) and what they've been working on lately. spotifycreators-web.app.link/e/gMnIk2ywAQb

MCP + WASM = 🚀

Pkl: Safe & Maintainable Config for Apps & Infrastructure • @jamesward.com • GOTO 2024 www.youtube.com/watch?v=yUmA...

Avoid costly configuration mistakes. Learn how Pkl provides a safer, more maintainable approach for Kubernetes, Spring, and beyond. Watch @jamesward.com’s talk to start using Pkl in your Java apps today!

Been writing some pretty normal Python code: async, resource management, error handling, cancellation handling. And OMG I miss Effects / ZIO. My code is spaghetti and it’s not my fault.

Some great stories of switching from Java to Kotlin in this thread: www.reddit.com/r/Kotlin/com...
