Silent Speech Interfaces: Why RF Beat the Electrodes
You're in the library, dictation app running, and you've just mouthed the same email four times into your laptop like a lunatic because speaking out loud would...

James Whitfield
James is a language nerd and systems thinker who believes most "new" ideas in computing are old ideas meeting new hardware. He covers programming languages, compilers, runtimes and emerging technology.
He likes to trace a feature back to the paper or mailing-list thread it came from, and to ask what the original designers would make of how it is used today.

Goose Language Bets Systems Code Doesn't Need a Heap
Here's a claim that will annoy at least two language communities: the borrow checker was a detour. Not a mistake — Rust's ownership model solved real problems...
Skeuomorphic Desktops Are a Rendering Problem, Not a Joke
Here's a claim that will annoy both camps: skeuomorphism never died because users hated it. It died because it was expensive — in pixels, in GPU cycles, and in...
Rust's Borrow Checker Bug: What Soundness Really Means
Rust's type system is supposed to make a hard promise: if your safe code compiles, it can't have dangling pointers, data races, or use-after-free. So when a...
Constrained Decoding: Turn LLMs Into Fast Decision Models
Here's a cheap trick that's quietly useful: if you only care about the first token an LLM would emit, you can ask it a multiple-choice question and get the...
The Lightbulb Computer Beats the Headset Vision
Spatial computing has a marketing problem: every "vision of the future" the industry ships involves strapping a screen to your face. Glasses, goggles, headsets...
Rob Pike's Programming Rules Are Still Right
In 1989, Rob Pike — who would later co-create Go, UTF-8, and Plan 9 — wrote down five rules of programming. They're short enough to fit on an index card and...
The Specification-Implementation Gap Is Where Bugs Live
There's a claim that surfaces periodically in programming language theory circles: 'a sufficiently detailed specification is indistinguishable from code.' The...
Embeddable Graph Databases Beyond SQLite
SQLite is everywhere. It's in your phone, your browser, your smart TV, probably your car. It solved a fundamental problem — giving applications a full SQL...
How JIT Compilers Make Dynamic Languages Fast
Ruby has a reputation for being slow. So does Python. So does JavaScript — or at least, it did, until V8 made it fast enough to run server-side workloads. The...
Java Keeps Getting Better and Nobody Notices
Java is the Rodney Dangerfield of programming languages: it gets no respect. Mention Java to most developers under 30 and they'll picture XML configuration...
CPU Branch Prediction: Your Code's Hidden Bottleneck
There's a famous Stack Overflow answer that's been viewed over 3 million times. The question: why is processing a sorted array faster than processing an...
What Building a Shell Teaches You About Unix
Every developer uses a shell daily. Few understand what it actually does. The shell looks like an application — you type commands, it runs them — but it's...
GPU-Accelerated Terminals: TTYs to Glyph Atlases
In 1978, Digital Equipment Corporation shipped the VT100. It was a piece of furniture — a CRT in a beige enclosure, wired to a minicomputer via serial cable....
Why Lisp Still Matters After Six Decades
Every few years, someone writes a 'Lisp is dead' essay, and every few years, someone else points out that half the features in their favorite modern language...
The Linux System APIs Every Developer Should Know
In 1969, Ken Thompson and Dennis Ritchie sat in a Bell Labs office and made a series of design decisions that would outlast nearly every other piece of...
Python's JIT Compiler Is Finally Happening
Python has been 'too slow' for as long as Python has existed. The standard response from the Python community — 'use C extensions for the hot loops' — has...
Why jemalloc Matters: Memory Allocation at Scale
Every time your program calls malloc(), something has to decide which chunk of virtual memory to hand back. This decision — trivial for a small program —...
VisiCalc and the Software That Made Hardware Worth Buying
Before VisiCalc, personal computers were toys for hobbyists. After VisiCalc, they were business tools. That's not an exaggeration — it's the documented sales...
How JPEG Compression Actually Works
JPEG is the cockroach of file formats. It was standardized in 1992, predates the web browser, and has survived every attempt to replace it. WebP, AVIF, HEIC —...
Why Great Software Takes Time and Can't Be Rushed
Flask took eight years to reach version 1.0. SQLite has been in active development since 2000 and still gets meaningful improvements. The Linux kernel is over...
