AI can draft the code. It still cannot infer your hidden contracts, architecture boundaries, or reviewer attention budget.

I wrote about context engineering, small task framing, MCP-style tool surfaces, and why the real cost comes back during verification.

Stop your agents from guessing!

#PlatformEngineering succeeds when reliability and ergonomics reinforce each other - not compete.

Explore 3 foundational pillars:
1️⃣ Automated reliability
2️⃣ Developer ergonomics
3️⃣ Operator ergonomics

Together, they create a Virtuous Cycle!

Quarkus has Signals now, but the interesting question is what they replace.

I wrote a NebulaTrack walkthrough that puts Signals next to CDI events, Reactive Messaging, and the Vert.x EventBus, then builds the three patterns that matter: `publish()`, `send()`, and typed `request()`.

#SoftwareArchitecture is never static. The question isn't whether change will happen, but whether that change is intentional / accidental.

Architectural Change Cases help teams make deliberate choices by clarifying how systems should evolve.

Want faster warm-up without rewriting your app? #Java25 embeds profiles into AOT caches and upgrades Shenandoah GC. @__amahdy explains what this means for real workloads — not just release notes.

Zero-trust only gets useful once you can tell whether a failure came from TLS, service identity, or business policy. This walkthrough builds three Quarkus services with app-managed mTLS, OIDC service tokens, and edge-only branch checks, then proves each failure path.

Ever tried debugging production issues across deeply nested reactive chains? That complexity gets brutal in high-I/O #AI systems. Damiana Nascimento explains when #VirtualThreads outperform reactive designs & where they don’t: https://t.co/EuNaGPboZe

Skill issue: Lessons from skilling up coding agents

Getting agents to actually use Langfuse was a "skill issue" — literally. Marc Klingen from Clickhouse on teaching coding agents to use new tools, and why it's harder than you think.

Still a bit rough around the edges, but already useful!

You can use our MCP for generating diagrams with local context.

Python isn’t the only way to build #AIAgents anymore. With #SpringAI, #Java apps get memory, RAG, tools & model switching—all behind one #API. Same code runs from local Ollama to AWS Bedrock.

25 years after the #AgileManifesto, should the original authors have a reunion?

@martinfowler's answer is surprisingly humble:
"We wrote the manifesto. Now it's for others to continue."

Plus a perfect punchline from @KentBeck 😄

Shared MCP servers get risky quickly: every action starts looking like the same service account.

I wrote about why IBM Bob deployments need delegated access, short-lived tokens, and audit-ready user or session attribution before shared MCP tools touch deployments, tickets, or customer data. https://t.co/32n5svoO2D #IBMBob #MCP #Security

AI-generated code without architecture verification is just automated technical debt.

Taikai turns architecture into executable tests and automatically validates AI-generated changes before merge. 🚀
Generate fast. Verify automatically. Ship confidently.

Cheap questions should not burn the same local model as real debugging work.

I wrote a Quarkus + LangChain4j tutorial that classifies prompts, routes them between two Ollama models, and keeps the decision observable with CDI events and tests.

This #InfoQ podcast breaks down the critical intersection of technical & social architecture.

Key takeaways:
• Business > Tech: How the company operates matters
• Focus on Outcomes: Good requirements look at problems to solve
• Embrace Constraints

This talk is a wild ride through #Java optimization, profiling, memory mapping, parallelism, and shaving milliseconds off a seemingly impossible problem.
