oftware as a Service means the software runs on someone else's servers and you pay for access to it. No installation, no maintenance, no infrastructure. Here is what SaaS actually is, how it changed software delivery, and the decisions behind when it makes sense vs owning your own stack.
Go is a statically typed, compiled language built at Google in 2009. It compiles to a single binary with no runtime dependency, starts in milliseconds, and handles concurrency through goroutines and channels. Docker, Kubernetes, and Terraform are all written in Go. Here is why.
Signing is encryption with the keys swapped, and that symmetry is exactly what makes the naive implementation breakable. Here are two forgeries executed against textbook RSA signatures, and what PSS does that hashing alone cannot.
Rust eliminates entire categories of bugs — null pointer dereferences, buffer overflows, data races, use-after-free — at compile time with no runtime overhead. Microsoft, Google, Amazon, and the Linux kernel all use it for systems code.
Git tracks every change to every file in your codebase, lets multiple developers work simultaneously without overwriting each other, and gives you a complete history you can rewind to any point. It is the foundation of modern software development. Here is how it actually works.
I exclusively used WordPress somewhere between 2008 to 2019 – if not earlier than that for me. At least eleven years. That's a good long time to
Kubernetes runs your Docker containers across a cluster of machines, handles scheduling, health checking, rolling deployments, auto-scaling, and self-healing. When your application outgrows a single server, Kubernetes is how it runs on ten.
Docker packages your application and everything it needs to run into a container that behaves identically on your laptop, your teammate's machine, and the production server. "It works on my machine" stops being a problem. Here is how it actually works and what production usage looks like.
Redis is an in-memory data structure store used as a cache, message broker, session store, rate limiter, and real-time leaderboard engine. I dropped it into production as a cache before I understood what it actually was. Here is what it is, how it works, and what it does well.
Tutorials that show you how to build an API in 50 lines of code are lying to you. This is what a production TypeScript API actually looks like — authentication, validation, error handling, rate limiting, database connection pooling, structured logging, and a test suite. All of it, from scratch.
An API is a contract between two pieces of software. One side defines what requests it accepts and what responses it sends. The other side follows that contract to get work done. Every app on your phone, every website pulling live data, and every service talking to another service uses APIs.
MySQL runs WordPress, which runs 43% of the web. It runs Facebook's original backend, YouTube, and GitHub. It is also a database with genuine quirks that bite people who do not know about them. Here is the full picture.
