on Ebpf, Linux, Observability, Security, Networking, Devops
When eBPF was introduced as a Linux networking feature in the mid-2010s, the goal was simple: let administrators write small, sandboxed programs that could filter packets in the kernel without modifying kernel source code. A useful-but-niche capability.

PostgreSQL 18 dropped in late 2025, and unlike some releases that feel incremental, this one has changes that will meaningfully affect real workloads. The headline feature — asynchronous I/O — has been in development for years and finally landed in a mature form. But there are several smaller features that will have more immediate impact for most applications.

Every major React release arrives with a new mental model to learn. React 16 brought Fiber. React 18 brought concurrent rendering and useTransition. React 20 — released in early 2026 — brings the React Compiler to stable, reshapes how Suspense works in server contexts, and introduces cache() as a first-class API for request-scoped memoization.
on Webassembly, Wasm, Edge computing, Cloud, Performance
When WebAssembly landed in browsers in 2017, the conversation was about running C++ games and video editors in a web tab. A reasonable but ultimately small idea.
