Your encrypted data may already be compromised. "Harvest now, decrypt later" means quantum computers could break today's encryption. Billy Korando explains the threat. #Security #Quantum #Encryption

AI's sycophantic "you're right!" is quietly destroying new engineers' judgment. Russ Miles on why discernment matters more than ever. #AI #Engineering #Mentorship

Smaller object headers = less memory, fewer GC pauses, lower latency. Billy Korando breaks down the JVM trick that boosts performance. #Java #JVM #Performance

Software engineering is decision-making. Russ Miles on how agentic AI changes who makes those decisions — and why the human stays accountable. #AI #SoftwareEngineering #Agents

Java devs, this is YOUR moment. Billy Korando says there's no better way to build generative AI than on the JVM — and the tools are racing to lead. #Java #GenAI #JVM

Writing a book about Spring Boot 4 reinvigorated his love of coding. He's shipping a new Spring AI Agents MD starter to the community soon. #SpringBoot #SpringAI #Java

Spring Boot 4 unlocks a whole chapter on distributed SQL. Jakarta EE alignment, null safety, resilience annotations, and more got this author excited. #SpringBoot4 #Java #CockroachDB

You have to understand the technology to trust what AI tells you. If the AI goes away tomorrow, do you actually know how your stack works? #AI #SoftwareEngineering

He wrote a book and yes, he used AI. No button-pushing, but AI helped with chapter outlines and example ideas. The honest middle ground of writing with AI. #AI #Writing #Spring

Your database tops out at 1,000 transactions per second, but millions are coming in. Use RabbitMQ as a buffer layer so you never overwhelm the downstream DB. #RabbitMQ #Scaling #Java

DaShaun Carter @dashaun.com · 25/09/2026
Producer and consumer never need to know the routing. RabbitMQ exchanges route messages anywhere, even across systems, without either side knowing. Huge fan. #RabbitMQ #Messaging #Java

Stop polling your database for changes. With GemFire, one query can push inserts, updates, and deletes straight to your app. One connection, updates almost instantly. #GemFire #Java #CDC

DaShaun Carter @dashaun.com · 24/09/2026
What if your cache was fast, distributed, and strongly consistent? GemFire is an in-memory data grid that works great with Spring. Move data logic closer to the data. #GemFire #Spring #Java

#ollama is not multi-agent friendly. As my workflows evolved with more agents and sub-agents #ollama became a bottleneck. I'm switching everything (except Raspberry Pi) over to #vllm. I'm using Docker, again, to keep it portable/flexible. github.com/dashaun/rtx5...

You're not underqualified — you're undersold. Keep a "wins document," become your own promoter, and track every win for your next promotion. Advice worth taking even 25 years in. #CareerGrowth #Tech

Spicy take: there's NO difference between networking and building relationships. Stop DMing strangers for favors. Treat people like humans, not like jobs. 🔥 #Networking #Tech #HotTake

A cold LinkedIn message so good it gave goosebumps — because they did this one thing differently. Networking is easy; building relationships takes more. Here's the playbook. #Networking #CareerTips

Everyone online screams "MERN stack, MERN stack." He researched the industry, saw the entry-level demand, and bet on Java instead. The career move nobody advised him to make. 🎙️ #Java #DevCareers

Getting to production isn't the goal anymore — maintainability is. In a fast-moving world, your ability to patch and update beats shipping fast. #SoftwareEngineering #Maintainability #DevLife

Nothing kills adoption faster than a 50-step README. Docker Compose means clone, run, done. No dependency hell. Onboarding pain, solved. #Docker #DevOps #OpenSource #DockerCompose

Your app doesn't need every feature on day one. Vibe coding is great, but without a clear MVP you build features nobody asked for. Build the core, expand later. #MVP #VibeCoding #ProductDevelopment

DaShaun Carter @dashaun.com · 19/09/2026
Stop polishing. Build an MVP, throw it away, and iterate. Five versions later, the constant that kept it together? Docker Compose. #DevLife #DockerCompose #SoftwareEngineering

Two NVIDIA DGX Sparks, one model. DeepSeek-V4-Flash, 284B params, full 1M-token context, across two DGX Sparks linked by QSFP/RoCE, driven entirely from my Mac over SSH. The 30-megabyte mistake that froze both nodes, the off-by-1 that wasn't, and every script I wrote so it never happens twice.

I was already building coding and DevOps agents with Spring AI when I realized that AGENTS.md could give me something I really needed: consistency. dashaun.com/posts/spring...

Spring Modulith gives you clean domain boundaries and event-driven decoupling without microservice network latency or ops overhead. You get strict architecture inside a single app, letting you move fast now and split into microservices later only if real scaling demands it.

My son just asked if RAM stands for "Real Actual Money" while he was watching a video of me and @starbuxman.joshlong.com talking about the value of upgrading. He knows what RAM is. He was being clever. My son is the actual author/source of many of the jokes I tell in public.
