Deploying Python APIs on Fly.io

Django REST Framework & FastAPI with PostgreSQL and Redis

A practical guide for developers and DevOps engineers seeking production-grade cloud deployments without the operational overhead of AWS or GCP. Covers the Fly.io platform (Firecracker micro-VMs, private WireGuard networking, the fly.toml contract), a cost and complexity comparison against AWS ECS/RDS and GCP Cloud Run, and production-ready configuration for Django DRF and FastAPI — including Dockerfiles, PostgreSQL provisioning, Redis, Celery, secrets, scaling, and a full launch checklist.

The JavaScript & ECMAScript Story

From a Ten-Day Hack in 1995 to the Language That Powers the Modern Web

JavaScript was written in ten days in 1995 by a single engineer at Netscape. Today it runs in every browser, on servers, on mobile, and at the edge. This paper traces the full arc — the browser wars and the birth of ECMAScript, the ES4 collapse, the transformative ES6 release, the rise of TypeScript, and the runtimes and frameworks that turned a form-validation script into the infrastructure of the modern internet. Written for developers at any level who want the historical and technical context behind the tools they use every day.
