The first live stream on spec-driven development is already over. Thank you all so much for participating. For those who couldn't be there, you can find the recording here: youtube.com/watch?v=jwPBHV…

Netflix's opinion on @java #java @JavaOne #netflix #javaone

Look mom, I’m on TV 😊 Java Together… The Power of You - JavaOne Keynote youtube.com/live/skc-nIFS-… Look mom, I’m on TV 😊

A great week at #javaone, with great content, meeing old friends and meeting new people. I gave a talk about how Netflix is using #java and had a few minutes on stage during the community keynote. Videos should be published soon.

Shipped something I’m SO proud of today!! :') I built our first @Oracle LiveLab with embedded FreeSQL worksheets, focused on JSON Relational Duality Views in @OracleDatabase 26ai. You can build duality views, run CRUD via JSON docs, and query nested data, all instantly in the browser 🔥 Try it out here: livelabs.oracle.com/ords/dbpm/r/li…

@leifastrand That sound huge!

Exciting new feature in Vaadin 25.1.0 rc1. View state values in signals are preserved when hotswapping. You stay where you were before but with new logic applied. Feels like using a completely new framework!

@BrianVerm at #JavaOne about a very important AI topic 👇

Hello #JavaOne

@CFDevelop Yes I prefer the Opus model.

@simas_ch You’re saying opus is the best? That’s been my findings but people are saying the latest OpenAI model has come a long way

I’m really sorry to say this but I’ve had no luck with Cline, Roo Code and Kilo Code combined with the cheaper models I can’t even get it to do basic MCP tasks that Claude Code handles with breeze I just need to know if it’s the models or the agent…

@maxandersen Me too. Especially because I like MCP and it works very well for me.

Bit tiered of seeing mcp is dead, use cli and APIs instead. It's more cli is now even more useful and you can call APIs including mcp APIs via a cli.

@bidhanxcode I’m not looking for a job at one of those companies

Google uses Go. Meta uses Go. Microsoft uses Go. Amazon uses Go. Uber uses Go. Dropbox uses Go. Cloudflare uses Go. Twitch uses Go. Docker uses Go. Kubernetes uses Go. PayPal uses Go. Shopify uses Go. What’s stopping you from learning Go?

🎁 Happy Friday - Opus 4.6 1M is now the default Opus model for Claude Code users on Max, Team, and Enterprise plans. Pro and Sonnet users can opt in with /extra-usage.

@systemsarch unifiedprocess.ai

@simas_ch Agreed! 2020: TDD, write tests first or you're a barbarian 2023: BDD, so business reads the tests 2026: SDD, write a clear spec or gherkins for devs, AI and business

Spec-Driven Development is not for developers alone. It is the bridge between business and development. Without business, there are no requirements. Without requirements, there are no specifications. And without specifications, teams may still build software, but not necessarily the right thing.

Why should is use Coplito CLI instead of Claude Code if use the Anthropic models anyway?

Lazy loading in Vaadin is this easy: Instead of loading all tasks into a grid, we can use setItemsPageable(...) to fetch data as needed and improve scalability, startup responsiveness, and backend efficiency. vaadin.com #Vaadin #Java #SpringBoot

@JamesWard @AAAzzam It’s dead as SOAP

@AAAzzam In AI years it lived a long, productive life. Curious though… are technology zombies the same thing as technologies that power the useful things?

MCP is dead. Join us for a celebration of its life on April 1 in NYC ahead of the MCP Dev Summit. Wear black. luma.com/htkxoidx

@sivalabs Super cool 🙌

I use SDKMAN all the time and use ".sdkmanrc" file to automatically set project-specific Java, Maven, Gradle versions. Created a simple IntelliJ IDEA Plugin to get autocompletion in .sdkmanrc file. github.com/sivaprasadredd…

@starbuxman @dashaun @JavaOne

what're you building today? Me, I'm working on my talks for @javaone next week! So excited! You gonna be there?
