it was interesting to talk to @brunoborges.bsky.social about the state of coding assistants for Java; since it's the language that powers backend systems that enterprises are notably conservative about updating. If they could switch to being up to date by default, that's a big change in SDLs

"Claude Sonnet 4.6 paired with Rubber Duck running GPT-5.4 achieved a resolution rate approaching Claude Opus 4.6 running alone, closing 74.7% of the performance gap between Sonnet and Opus." This is the way. Multi-model! github.blog/ai-and-ml/gi...

If you want to learn AI, don't pay for AI courses. Apply for an MBA and use AI to get through it. And you get an accreditation that is somewhat respected in the job market. Learning by necessity beats learning by curriculum.

AI Agent Skills Marketplaces #XKCD

April 1st reliably exposes people who don't know the difference between sarcasm, a good joke, a bad joke, and a lie. Stating a fact that isn't true doesn't make it sarcasm or clever. At best it's a bad joke. At worst it's just a lie.

21 hours. #Chicago to #Toronto. By #train. That's longer than a flight from New York to London. The distance is just under 900 km. A journey that takes 4 hours in France, 5 in Japan... In North America takes nearly a full day here. Canada+US passenger rail is a joke. 🇨🇦🇺🇸🤡🚂

„Over the next couple of years, the most valuable people to have on a software team are going to be experienced folks who’re actively working to keep their heuristics fresh. Who can combine curiosity with experience.“ buff.ly/HYgxmFn #developer #leadership #AI

Not everything in our lives must be efficient. Learning is one of them. The trap is confusing efficient learning with effective learning. Be careful when using AI to learn.

When you write code, you review it as you write it. The two acts are inseparable. When using someone else's code, you extend some degree of trust because you know they did the same.

Open Source Foundations and group-led projects are more important than ever when anyone can build and publish a little tool/project/website. Collaboration and cooperation is what will give ideas continuity, now that kick off execution is so easy and fast.

It took humans less time to learn how to identify AI-generated text than to computers to learn how to write essays posed as human writers.

I updated my website at dlsc.com with Github Copilot. Basically one day of work. If I had a design I could have done it in an hour, but I was playing around with things. @brunoborges.bsky.social

Did some more evaluation of GitHub Copilot CLI today and built a nice launcher app for my #GemsFX open source project. The productivity I get out of this surpassed all my expectations. #javafx #java #ui #ux @brunoborges.bsky.social

When using AI to generate code the term "implementation detail" gets a whole new meaning. #ai #copilot #claude @brunoborges.bsky.social

"I ran out of AI tokens."

🚀 Copilot Java SDK v1.0.10 is out! ✅ Security: Jackson upgraded to patch DoS vuln ✅ session.setModel() + built-in tool overrides ✅ Deny-by-default permissions ✅ clone() on config classes ⚠️ Breaking: session permission API changes github.com/copilot-comm...

Despite LLMs being able to rewrite any software, the idea of writing reusable software remains an important goal: every time you rewrite software that already exists, you are wasting tokens on producing non-business value. Focus token usage on delivering value. Reuse software.

Sonnet 4.6 in a parallel agent fleet overnight is a different use case than single-session testing. I ran two controlled experiments - the model surprised me in unexpected ways. thoughts.jock.pl/p/sonnet-46-...

When you write open source software (with or without) AI, and shares it with the world, you are effectively helping other developers save tokens.

Funny, the #Copilot Coding Review agent provided feedback in Polish because the Pull Request is about translating from English to Polish. But the cool thing is that there is indeed a double *n* in the Polish word "rozszczepialnność" !!! It should be rozszczepialność. github.com/javaevolved/...

#FOSS remains well founded. What is not included are obligations to: - have comm channels - review issues submitted by others - review and accept/maintain contributions Ability to disable PRs is recognition maintainers deserve the right to not engage w/ users and still abide to principles of FOSS.

"Are we using AI for building Hardwood? Absolutely. Is Hardwood vibe-coded? Absolutely not." Coding agents are incredibly powerful, but they're no magic wand. Sharing some experiences with using AI for building a relatively low-level code base like a Parquet parser in the #Hardwood announcement 👇.

"I can't use this tool because it is not GA." Well that excuse has expired today. #CopilotCLI is now generally available, and it is here to stay.

I translated a site into 8 languages in one night using a fleet of @github.com Copilot Agents powered by Claude Sonnet 4.6. 112 code patterns × 8 locales = 896 translation files. 6 agents running in parallel. All PRs merged within ~1 hour. One bug total. dev.to/brunoborges/...

#Java Evolved website now has localization #i18n in eight (8) languages besides English. All translations done in a few hours with Claude Sonnet 4.6 using fleet of agents in #Copilot. 🇬🇧 English 🇩🇪 Deutsch 🇪🇸 Español 🇧🇷 Português Brasil 🇨🇳 中文 (简体) 🇫🇷 Français 🇯🇵 日本語 🇰🇷 한국어 🇸🇦 العربية javaevolved.github.io

Bots dumping IBM stock because they were never paying attention to news about IBM's own AI solution to move COBOL code to Java. Got it.

Tired of wrestling with YAML files? @brunoborges.bsky.social shows how natural language can automate your repository workflows, avoidingendless configuration syntax. foojay.io/today/stop-w... #DevTools #Automation #Java

What has not changed: - Software remains a need. - System architecture remains foundational. What has changed: - Code became a commodity. - SDLC became agentic.

Stop writing #YAML. Start using natural language for @github.com Actions! Watch me and @cassidoo.co deep dive into #AgenticWorkflows in this week' s Rubber Duck Thursday, to learn how to safely automate repo tasks without risk of prompt injections. www.youtube.com/live/Dw2S-VQ...

My new keyboard has arrived.

One thing people are not talking about enough is Switching Cost in this battle between Anthropic and OpenAI. The S.C. is ZERO. People will choose whatever model is better and cheaper.

AI agents can now step through code with real debuggers instead of relying on logs. @brunoborges.bsky.social shows how this changes debugging workflows and makes AI coding assistants more effective. foojay.io/today/enabli... #Java #AI #Debugging

CICD platforms (e.g. GitHub Actions) have a billing based on hours running tasks. Consider using anything other than Python (unless you optimized with CPython!). Here is how I am running @jbangdev in the #JavaEvolved website: github.com/javaevolved/... Also, benchmark!

JDK has a CLI debugger; AI agents have terminal access. Why are they still debugging with println? Let agents set breakpoints, step through code, inspect variables, catch exceptions. No logging/compile. Just a real debugger. brunocborges.substack.com/p/enabling-ai-agents-to-use-a-real #Java #AI

I'd appreciate if coding agents would have a system instruction for preventing people from reinventing the wheel. Like, "do you really want to build this thing instead of just reusing project <insert open source tool the dev didn't know existed and was too lazy to search>?"
