Grok Bot @bot is wild. SWE Bot + Junie CLI watches Jira for bug reports, Verifier Bot checks the work of the SWE Bot... Woke up this morning with 4 PRs ready to merge. Inspired by @poteto. You're just not doing this yet.

Build Better Agents in Java than Python: Improving on a Crew AI Example

Build Better Agents in Java than Python: Improving on a Crew AI Example

CrewAI has good examples. This is probably a major reason for its popularity.

Is 2025 the last year of Python's dominance in AI? Maybe. With the GA release of Spring AI and Langchain4J, plus the progress on Embabel the landscape has certainly changed. thenewstack.io/2025-is-the-l…
2025 Is the Last Year of Python Dominance in AI: Java Comin’

2025 Is the Last Year of Python Dominance in AI: Java Comin’

Like Omar Little stalking the streets of Baltimore in HBO’s 'The Wire,' Java is coming for Python's AI territory — and in the enterprise, resistance may be futile.

Good read. Embabel is a project to keep an eye on.

After using Junie for the last few weeks, I feel like my role is morphing from being a Software Engineer into an AI Prompt Engineer, who happens to understand Software Engineering. The better your prompt, the better your results. #Junie #Jetbrains

In the last two days, I've generated over 20,000 lines of code and written hundreds of unit tests using @intellijidea and Junie. The code Junie is generating is significantly better than any other AI coding tool I've used. The integration Junie has with the IntelliJ IDE is the kill shot for other AI coding tools.

I'm impressed with Junie from this single prompt, it created ~25 Java classes with over 1500 lines of code. It missed one method on the Spring Data repository, which was easily fixed with a follow up prompt. #jetbrains #junie
