- After sharing the ZeroLeaks report (big shout to Lucas Valbuena), I got few DMs asking about OpenClaw, AWS, and whether it can actually be secured. Here’s my take on it...and how I’d approach it. www.linkedin.com/pulse/harden...
- Ever feel busy all day but still struggle to get real work done? We’ve spent years optimizing the cloud: cost, performance, efficiency. But we rarely apply the same rigor to how we actually work. This article is about why that happens… www.linkedin.com/pulse/effici...
- RIP Scott Adam. Enjoyed Dilbert for decades.
- 2025 was a wild ride I never saw coming. Now it’s time for Stop-endo: stopping the setbacks and letting the endo-stoppable energy begin. Happy New Year to everyone!
- Starting a new series on Embedded AI and efficient compute. Before we talk satellites or Amazon Leo, we need to understand what really happens inside attention. So I ran the experiments on a MacBook. Turns out attention is way sparser than we think. www.linkedin.com/pulse/why-ai...
- Ready for Werner ’s keynote . Always the dose of reality and architecture we need. Efficient compute, AI, and a legendary T-shirt. Any guesses on today’s one? 😄 #AWS #reInvent
- Are you at re:Invent? I’m not there physically this year, but you can still grab some limited-edition Buildercards... there are a few surprises waiting for you. Just swing by the #Buildercards space in the Caesars Forum and make sure you don’t miss yours! #AWSreInvent
- My friend Christian is swimming 80 km from Tenerife to La Gomera and back. Not for glory, but to support disadvantaged families in Nepal with the Vicente Ferrer Foundation. Every stroke is hope. Proud of his courage, purpose and heart. Follow live: share.garmin.com/BrazadasSoli...
- MetalNES emulates the Nintendo NES transistor-by-transistor. Same dev who built the fastest NES emulator in the 90s… came back to build the slowest on purpose. This is not nostalgia. It’s hardware archaeology. (And yes, we show how to run it.) www.linkedin.com/pulse/metaln...
- For decades, Python said: “Sure, I’ll run all your threads... one at a time.” 😅 Now, with 3.14t (no-GIL), it finally means it. Parallel threads. Multi-core scaling. Real performance gains. www.linkedin.com/pulse/python...
- A sad day. Jane Goodall shaped my passion for nature, along with Jacques Cousteau. In 1987 she even helped my father’s expedition in DRC, investing all she earned back into primate conservation. One of a kind. Impossible not to love her. RIP Jane.
- Qualcomm used to be “the Snapdragon company", where phones and mobile dominance were its flagship. But the story has changed. From clusters in the cloud to glasses on your face, Qualcomm is trying to build a continuum of compute. www.linkedin.com/pulse/qualco...
- Cloud isn’t just racks and APIs anymore. With AI, it comes down to chips, memory, and networks. I put together a blog on how AWS Trainium2 impacts the game, from scale-up fabrics to memory bandwidth that actually keeps the math engines busy. www.linkedin.com/pulse/silico...
- Last night my eldest had some friends over. When I got home, I found them all deep into the Oculus 2 and 3… future metaverse engineers in training 😂
- Reading about Oxide’s $100M Series B took me back to the early vBlock days, when we tried to bring cloud-like experiences on-prem. Oxide feels like the version we always wanted. Not just servers, but a cloud rack with an engineer’s soul. Worth watching. www.linkedin.com/pulse/reinve...
- Before hyperscale cloud ruled everything, the story was different. I lived part of it, designing and deploying enterprise cloud regions at CSC. In this blog, I revisit the lessons from those early days, with anecdotes and headaches from the field. www.linkedin.com/pulse/tracin...
- Programming languages don’t just shape applications - they shape infrastructure revolutions. From Ruby on Rails to Rust, here is how they’ve helped in the cloud era and now in the AI space. www.linkedin.com/pulse/from-r...
- Not all AI needs a GPU. While the spotlight’s on giant models + GPU farms, real-world AI often runs just fine on CPUs. Docs generators, copilots, lightweight inference on Graviton… efficient, affordable, and overlooked. www.linkedin.com/pulse/all-ai...
- Tech stocks dragged the Nasdaq down today — Nvidia, AMD and Marvell all hit hard. But Intel surprised everyone, soaring nearly 7% thanks to SoftBank’s $2B bet and possible U.S. government backing. Sometimes the market flips the script.
- No more fixed GPU assignments. With Dynamic Resource Allocation on #AmazonEKS, your AI workloads get the GPU power they need, when they need it — boosting efficiency & cutting costs. www.linkedin.com/pulse/squeez... #Kubernetes #EKS #GPU #AI #CloudComputing
- From cooling breakthroughs to orchestrating 100K-node Kubernetes clusters on Amazon EKS — see how hyperscale AI infrastructure is built at AWS. www.linkedin.com/pulse/scalin... #AWS #EKS #Kubernetes #AI #Cloud #HPC #Scalability #AIInfrastructure
- Kubernetes autoscaling done right. My friend & colleague Christian just wrote the book covering the good, the bad, and “why is this pod even here?” moments from running K8s in production. Now on pre-order: a.co/d/3xPa3RJ
- Trump hits chips with 100% tariffs to force domestic production. Global supply chains shake—Apple pledges $600B to stay in the clear. Welcome to Trade War 2.0.

- What are the chances? You go in for a stress test with a cardiologist… and it turns out his son works at AWS!
- We once explored building a gaming fabric on AMD (CPU + Radeon). Gaming studios loved it—until hyperscaler realities got in the way. Now, with MI300X, EPYC Genoa & ROCm maturing… is AMD finally having its moment? www.linkedin.com/pulse/what-a...
- A handmade CPU. No IDE. No Git. No CI/CD. Just EPROMs, solder, and 1,800 lines of code. EPROMINT isn’t just a CPU — it’s a love letter to old-school computing. Proof that with curiosity and wire, you can build magic without a billion-dollar fab. www.linkedin.com/pulse/epromi...
- While everyone’s chasing GPU clusters, Arm has been quietly slipping into the heart of the datacenter. Less heat. Lower cost. More performance-per-watt. It’s not a side story — it’s the new foundation. www.linkedin.com/pulse/from-m... #Arm #Datacenter #EfficientCompute #ArmDeveloper
- New blog: Open Hardware vs Patent Saturation Is the open hardware movement under threat? From MMUs to shady patents, here’s a deep dive into what’s really at stake. Inspired by @josefprusa ’s letter—with a personal twist. www.linkedin.com/pulse/open-h...
- Watching top engineers leave and reading the latest Intel headlines made me reflect: What would you do if you had to reinvent a giant mid-fall? Here’s my take on how Intel could rise again — if it dares to rethink everything. www.linkedin.com/posts/gruize...
