Chaintip freshness cert: signed identity scores that age with the chain

A schnorr signature tells you who. A timestamp tells you when. A chaintip tells you when honestly. A chaintip with a TTL tells you when, and how long it's still good for. That last piece is what shipped today on the Depth-of-Identity Oracle. If you follow the softwar conversation (Lowery's Softwar, Paparo's INDOPACOM testimony, the Bitcoin Policy Institute's recent press cycle), the framing matte...

I shipped an AI pipeline in a month that reads Reddit, HN, and X for startup ideas. The hardest part wasn't the AI.

For the last month I've been building MonetScope — a pipeline that crawls Reddit, Hacker News, and X, reads what real people are complaining about, and surfaces the complaints as scored startup opportunities. Going in, I assumed the hard part would be the AI layer. You know the story: prompt engineering, structured output, temperature tuning. That's where the demos happen and where most of the bl...

Building a mobile app landing page template with Next.js 14 — design decisions and lessons learned

Building a mobile app landing page template with Next.js 14 Most mobile app landing pages I see fall into two categories: generic Bootstrap sites or over-engineered Webflow builds. Neither feels right for an indie developer launching something they care about. So I built a template that sits in the middle — handcrafted, warm, and fast to customize. Design direction I delibe...

What to Include in a Bug Report: Console Errors, Network Logs, and Why Templates Aren't Enough

It's standup. Someone picks up a ticket. The title says "Login broken." The description says "See screenshot" but there's no screenshot. Priority is marked "High" — which on this project means nothing, because everything is marked High. The developer spends 20 minutes trying to reproduce, gives up, pings the reporter, waits four hours for a reply: "Oh I think it was in Firefox? Maybe Chrome." The...

Clean Code Is a Trap, Decompose Instead for Physics and Performance

Engineering teams obsess over clean code because they want software to look organized and logical in the text editor. Principles like SOLID get followed strictly, and hours get spent debating folder structures, because it feels like the disciplined way to build software. But this desire for logical cleanliness often leads into a trap where teams build systems that are beautiful to read but terribl...

I Had No Idea Which Endpoint Was Slowest. So I Built My Own Metrics.

In Part 10, I added structured logging and request IDs. I could now trace a single request through my entire backend — every log line tagged, searchable, debuggable in seconds. But I still couldn't answer basic questions: How many requests did /entries handle today? What's the average response time for /login? Which endpoint is the slowest? Are errors increasing? I had detailed logs for indiv...

Quality culture vs quality theatre — what inspectors actually notice

I’ve been on both sides of audits and inspections enough times to tell which companies have genuine quality culture and which are performing for the auditor. To be fair, the distinction isn’t always black-and-white — teams can be sincere but under-resourced — but inspectors are remarkably good at spotting theatre. In practice this means they look for repeatable behaviour, not polished slides. ...

Zelenskyy "In any normal country, purchasing stolen goods is an act that entails legal liability. This applies, in particular, to grain stolen by Russia. Another vessel carrying such grain has arrived at a port in Israel and is preparing to unload. This is not – and cannot be – legitimate business."

GoGPU - 790K Lines of Pure Go: Multi-Window GPU Apps, DXIL Compiler, and Why We Don't Need CGO

"Go deserves more support in GUI development" — r/golang, October 2024 That Reddit post hit a nerve. Hundreds of upvotes, dozens of comments echoing the same frustration: Go has world-class networking, databases, and CLI tools — but when it comes to graphics and GUI, the ecosystem says "just use Electron" or "call into C." I'd been planning a Pure Go GPU stack for years. Spent the year before ...
