A deep look at how Microsoft's Go-based TypeScript 7 compiler achieves its speed gains, and what the Visual Studio Code team's year-long migration reveals about adopting it safely.
Web Development
TypeScript 7.0 has officially launched, bringing a native Go-based compiler with 8x to 12x faster build times. Here's what shipped, how to install it, and how to migrate safely.
Programming
Python 3.15 ships a built-in frozendict — hashable, O(1) lookups, order-preserving, thread-safe by design. Here's the full technical picture: the 14-year history, how hashing works, what it unlocks for lru_cache and free-threaded Python, and every sharp edge you need to know before you use it.
Programming Languages
The dev community has spent 20 years calling Markdown 'just a markup language.' They're wrong. Here's the full technical case — parse trees, AST internals, the CommonMark spec, Pandoc's extended grammar — plus why Markdown is the fastest way to write long documents that has ever existed.
Programming
CPython has had informal WebAssembly support since Python 3.11. PEP 816 changes that. Brett Cannon just locked down exactly which WASI and SDK versions each Python release will target — and why SDK versions 26 and 27 got blacklisted entirely.

TypeScript 6.0 dropped today. It's the last version of TypeScript written in TypeScript. Strict mode is on by default, ES5 is gone, outFile is dead, and TypeScript 7.0 — rewritten in Go — is right behind it. Here's everything that changed and what you actually need to do.
Programming
Go is Google's compiled language built for simplicity and brutal concurrency. Here's what it is, how it works, and why it runs half the cloud infrastructure you use every day.
Software Development
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.
Programming
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.
Programming
Java has been declared dead approximately forty times since 1995. It still runs Minecraft, Android, LinkedIn, Twitter's backend, and the financial systems that process your paycheck. Here is what the language actually is, how the JVM works, and why it refuses to die.
Programming
Python runs Instagram, Dropbox, Netflix, Spotify, and Reddit. It trains the models that power modern AI. It processes petabytes of data in enterprise pipelines. And I ignored it for years because I thought it was just for academics. Here is what changed my mind.
Software Development
Past the benchmark charts and feature matrices — here's what Deno's permission system and Bun's native APIs look like when you build something real with them. The gotchas, the sharp edges, and the parts that are actually better than Node.
