Bring back MiniDV with this Raspberry Pi FireWire HAT In my last post, I showed you to use FireWire on a Raspberry Pi with a PCI Express IEEE 1394 adapter. Now I'll show you how I'm using a new FireWire HAT and a PiSugar3 Plus battery to make a portable MRU, or 'Memory Recording Unit', to replace tape in old...
Hold on to Your Hardware A warning about rising prices, vanishing consumer choice, and a future where owning a computer may matter more than ever as hardware, power, and control drift toward data centers and away from people.
Sharing a Name My bank card never arrived. I called the bank and, after being redirected through several departments, was assured that it had been mailed. Then we argued a bit about what "7 to 10 business days" mean

An embedding compression experiment for vector search An experiment in vector search storage reduction and embedding compression, comparing dimensionality reduction, fp16, and quantization without breaking search quality.
How much precision can you squeeze out of a table? When you interpolate a function from a table of values, higher order interpolation may reduce pure interpolation error while increasing numerical error.
Every Venture Is Either a Commodity or a Brand Every venture is either a commodity or a brand, and AI is forcing the question. It dissolved the building difficulty that let founders pretend they were brands.
From error-handling to structured concurrency How should errors propagate in concurrent programs? We start from that question, work step by step, and end up reinventing structured concurrency. Some reflections on why this matters as much during development as in production.
It Depends That's the answer I would always get from the lead developer on my team, many years ago. I wanted clear, concise answers from someone with experience, yet he never said "Yes" or "No." It was always "I
How I Use Claude Code to Build Features My current workflow for building features with Claude Code: plan mode, a living SPEC.md, TDD, and how to resume sessions without losing context
Yes, Learning to Code Is Still Valuable Every few weeks, someone shares a bold opinion: "Don't bother learning to code, AI will do it all." I've seen this from VCs, influencers, and people who have...

The Unreasonable Effectiveness of Linear Search (evanjones.ca) Thanks to programming interviews, we have memorized that a binary search performs O(log n) comparisons, while a linear search performs O(n), so a binary search is going to be faster. Unfortunately, this ignores the constant factors. Linear search is the s...
