Hugging Face just rolled out a sharp set of free AI courses. Real topics, real tools—think **AI agents, LLMs, diffusion models, deep RL**, and more. It’s hands-on from the jump, packed with frameworks like LangGraph, Diffusers, and Stable Baselines3. You don’t just read about models—you build ‘em i..

Search is a fundamental problem in computing, and vector search aims to match meanings rather than exact words. By converting queries and documents into numerical vectors and calculating similarity, vector search retrieves contextually relevant results. In this tutorial, a vector search system is bu..

Malicious npm packages just leveled up: this one dropped a self-spreading worm that hijacks repos and leaks secrets the moment it lands. It abuses `postinstall` scripts to run TruffleHog and swipe tokens straight from your codebase. Then it uses GitHub Actions to exfiltrate the loot and auto-publis..

When an event drops silently in a distributed system, it is not a bug, it is an architectural blind spot. Detect, debug, and prevent message loss in Kafka-based streaming pipelines using tools like OpenTelemetry, Fluent Bit, Jaeger, and dead-letter queues. Make sure observability gaps in event strea..

Azure logs come in three flavors: **Activity Logs**, **Diagnostic Logs**, and **Log Analytics**. Each with its own rules for retention and billing. The catch? Those differences aren’t quirks—they’re baked in...

Duolingo’s FinOps crew didn’t just track cloud costs—they wired up sharp, automated observability across 100+ microservices. Real-time alerts now catch AI and infra spend spikes before they torch the budget. They sliced TTS costs by 40% with in-memory caching. Dumped pricey CloudWatch metrics for P..

A teardown of Argo CD anti-patterns calls out 28 common misfires—stuff like skipping Git for Application CRDs or stuffing Helm/Kustomize config right into Argo CD manifests. Yikes. It pushes for a cleaner setup: use **ApplicationSets** instead of rolling your own YAML, turn on **auto-sync/self-heal..

DigitalOcean just dropped **Organizations**—a real upgrade for anyone juggling multiple Teams. Think one top-level account to rule them all: centralized user control, one invoice to track, and org-wide settings for taxes, credits, and permissions...

OneUptime shows how to put **error budgets** to work—keeping feature velocity in check without tanking reliability. The goal: ship fast, stay within SLOs. They do it by tracking **burn rates**, syncing across teams, and tuning SLOs to match how users actually use the product. Less guesswork, more s..

Databricks replaced default Kubernetes load balancing for a **proxyless, client-side gRPC setup**, wired up through a custom control plane. No more **CoreDNS**. No more **kube-proxy**. Clients now get live endpoint discovery through **xDS**, plus smarter routing tricks like **Power of Two Choices** ..
