In this guide, we’ll learn how to deploy a simple Pod in Google Kubernetes Engine (GKE) and expose it to the outside world using a LoadBalancer Service — all in a declarative way (using YAML manifests). Step 01: Understanding Kubernetes YAML Top-Level Objects Every Kubernetes resource is defined in a YAML manifest.The top-level objects you’ll…

The United States government has confirmed new visa allocations for 2025, aimed at addressing labor shortages in specific industries. Thousands of temporary and seasonal work visas will be made available, particularly under the H-2B program. At the same time, policy adjustments in the H-1B program are expected to affect skilled workers with higher fees and…

Em um projeto de software é comum precisar testar uma funcionalidade que está sendo ou foi desenvolvida. Nos projetos em que o código roda em um servidor, isso pode envolver o deploy em algum ambiente específico, permitindo assim testar uma versão específica do código interagindo com as aplicações cliente ou demais serviços. Porém quando mais…

When I moved to Germany, I quickly realized how easy it was to lose touch with people who mattered to me. Between new personal responsibilities, career demands, and adjusting to a new culture, staying connected fell by the wayside. Months would slip by without a real conversation. At best, I’d exchange a few short messages…

Indie devs, I see you. Pixel-pushing that landing page. Debating if that button should be 1px taller. Sitting on 0.100.0 releases because “it’s not 1.0 ready.” Guess what? Nobody cares. Users don’t read semver like you do. They care if you ship, if it works, and if you improve fast. The Fear of 1.0 I’ve…

Walking Into the Gym for the First Time Imagine this: you’ve finally made the decision to improve your health (this is my personal experience). You walk into a gym for the first time, surrounded by endless machines — strange contraptions of metal and cables. You see people confidently lifting, pushing, pulling. Meanwhile, you’re standing there…

For years, our digital lives have revolved around a constellation of applications. From project management suites to sophisticated photo editors, we’ve come to expect a tool for every task. But what if this paradigm is fundamentally flawed? What if the very apps we rely on are becoming obsolete, replaced by a new era of instantly…

Choosing networking options on EC2. 🚀 1. Elastic Network Adapter (ENA) ⚡ 2. Elastic Fabric Adapter (EFA) 🔑 Key Differences Feature ENA EFA Protocol TCP/IP stack OS-bypass + MPI (via libfabric) Latency Low, but limited by TCP/IP Ultra-low (microsecond-level) Throughput Up to 100 Gbps Up to 100 Gbps (but optimized for small-message, HPC traffic) Use…

Remember that moment when you’re deep in debugging at 2 AM, staring at a gnarly database schema, and you just want to ask: “Hey DB, which users haven’t logged in for the past 30 days?” Instead, you end up crafting some SQL monstrosity, second-guessing your joins, and probably making three syntax errors before you get…

I’ve spent the past 13 years in software engineering—and, call me a masochist, but my favorite part is still running face-first into unfamiliar tech and coming out the other side. If you’re a jack-of-all-trades like me, you know the drill: you can dance through AWS, sprinkle some YAML, chat about machine learning infra, and even…
