Go - Traces vs logs, and the four ways I got a trace tree wrong

Metrics and logs were the easy part, and I wasn't ready for traces. It took me a while to get it, first getting a grasp on the vocabulary, then putting it all together and managing to see a tree. I won't blame myself too much, because a trace tree has several ways to fail silently, and I hit them one after another on the same code. This is the post I wish I'd read first. Not an OpenTelemetry tut...

Go - Sending traces, logs and metrics to the Victoria* stack

The VictoriaMetrics folks now have a component for each OTel signal: VictoriaMetrics for metrics, VictoriaLogs for logs, and VictoriaTraces for traces. Nice. No collector needed, the Go SDK can talk to all three directly over OTLP/HTTP. The catch: each one listens on its own port, with its own path, and the paths are almost consistent. Almost. First, the dependency dance The OTel Go S...

From Spaghetti to Structure: The Architecture Patterns Every Software Developer Should Know

Ever inherited a codebase where changing one thing breaks five others? That’s rarely a coding problem. It’s an architecture one. When you first join a software team, code organization feels simple. You put database queries in one folder, business logic in another, and UI routes at the top. It feels clean and logical. Then the product hits real-world scale. Deadlines tighten. Business models pi...

Sandboxing Patterns for Local AI Agents With Filesystem Access

A while back I wrote about running local AI agents on your own code, and it became the most-read thing I've published. The most common follow-up question, by a wide margin: "okay, but you gave it write access to your disk, doesn't that terrify you?" It should, a little. The first week I had a local agent with real filesystem tools, it "cleaned up" a directory by rewriting a config file I hadn't a...

I Built a Temp Mail & Webhook Tool — Reddit Instantly Thought I Was a Spammer

I spent the better part of two weeks living on caffeine, error logs, and the kind of optimism only a solo developer at 3 AM can produce. The goal was simple, or at least it sounded simple when I wrote it on a sticky note: build a clean, fast, free developer toolbox. No signups. No dark patterns. No "upgrade to Pro to copy your own output." I called it YoBox — a single home for the small tools dev...

The Velocity Crisis - Rethinking Code Review in the Age of Agentic Coding

The Velocity Crisis - Rethinking Code Review in the Age of Agentic Coding The Bottleneck has Shifted: For decades, the primary constraint in software development was the speed at which a human could type code into a terminal. To manage the errors inherent in human fallibility, such as a subtle race condition introduced late on a Friday, code review evolved from informal peer checking into the stru...

Optimistic React UIs that don't drift from the server

I don’t ship optimistic UI to make things “feel fast”; I ship it because the p95 round-trip to a different region is 120–250 ms and users will mash buttons if the UI stalls. The failure mode to design around isn’t slowness. It’s state drift: the client shows one thing while the server has another, and your next write explodes with 412 Precondition Failed or, worse, silently corrupts data. ...

Voice Assistants Are Designed in the Silence

A voice assistant can be technically correct and still feel broken. The failure often begins after the user finishes speaking. Nothing dramatic happens. There is simply a pause: long enough for the user to wonder whether the system heard them, but short enough for each service dashboard to report an acceptable result. That pause is the product. Users do not experience speech recognition, a languag...

Your First Voice AI App Shouldn’t Start With a WebSocket

The first successful voice feature usually looks unimpressive: one audio file goes in, and one useful transcript comes out. That is not a toy result. It is the shortest route to the questions that decide whether a voice product will work. Does the transcript preserve names and numbers? Are speaker turns separated? Are timestamps useful downstream? Can the system handle the audio your users will a...

Is your sitemap.xml quietly broken? A 1-line way to check

The sitemap you set up once and never checked again A sitemap.xml helps search engines discover and crawl your pages efficiently. But a single stray character makes the whole file invalid XML — and crawlers just silently skip it. Or it points at an old path after a migration. Or it's empty. Nothing tells you. You just get crawled less thoroughly. I added a free sitemap check to OGCheck...
