I work at a B2B telecom consultancy. I'm not the one auditing the bills, but every month I watch how it's done: open the invoice PDF, check every line against the signed contract, compare it with what the account used in earlier cycles, and write up whatever doesn't add up. It's slow, it doesn't scale, and it's the first task dropped when the month gets busy — which is exactly when the money leaks. And outside a consultancy it's worse: most companies just pay the bill because it arrived....

I had twenty-two passing tests and two separate reviewers on a piece of code. None of it objected. Then I pointed it at a real API owned by somebody else and it broke on the first live read. The mismatch fit in one sentence: my parser required ISO 8601, the documented API returned Unix seconds. The repair was not one line. It touched five files, 74 lines of parser and 52 lines of tests. The assumption was small; making it safe was not. Here is why nothing caught it, and it is the part wo...

The Battery-Free Smart Card Revolution: A Hands-On Review of NFC Energy-Harvesting MCU PCBs In professional networking, first impressions are everything. But in a landscape crowded with QR codes and cheap plastic tap-to-share cards, how does a high-tier developer, cybersecurity expert, or tech founder stand out? Enter the NFC Energy-Harvesting MCU PCB Business Card . It’s not just a card; it's a fully functional, battery-free embedded system packed inside a 1.6mm-thick piece of FR-4 ...

A merchant running a small programme finds that percentage-based apps charge more as sales grow, while flat-fee tools often rely on third-party cookies that browsers increasingly block. I build ZeroCut. The app charges a fixed monthly fee — Free, $19, or $39 — with 0% commission on tracked sales, enforced server-side. Attribution follows three signals in order: a _zc_ref cart attribute from the theme embed, a real Shopify discount code per affiliate, then the landing_site query param. A 30-d...

Teaching an AI agent to upgrade .NET, React, and Next.js apps for real — not just talk about it Every engineering team has that repo. The one running a framework version from three or four years ago. Everyone knows it needs an upgrade. Nobody wants to be the one who breaks production doing it. That's the problem UpgradePilot — an open-source, multi-agent upgrade pipeline — is built to solve. And this week we shipped the piece that made it stack-agnostic: real, working upgrade automation f...

When I first started learning HTML, I thought it would be the easiest part of web development. The basic tags seemed straightforward, and creating a simple page didn't take long. But as I kept learning, I realized that HTML is more than just putting elements on a page. Understanding semantic HTML , proper document structure, forms, accessibility, and knowing which element to use in different situations takes practice. For example, it can be tempting to use for almost everything, but lea...

Most AI agent demos work beautifully. Then they hit real users, real data, and real edge cases — and start booking the wrong meetings, leaking context, or looping forever on a task they can't finish. The gap between "impressive demo" and "dependable system" is almost never the model. It's the guardrails around it. This is a practical guide to why agents fail once they leave the demo, and the concrete controls that make them safe to run in production. Why demos lie A demo is ...

I recently dug out my CDs and started reripping them all. I've found a few forgotten gems in there, but few hit harder for me than the beautifully concise Professor Murder Rides the Subway EP. There was a period of time in the mid-aughts in NYC where it seemed like every indie band wanted you […]

I wanted to sell a small digital product without building accounts, checkout pages, license-key emails, or a database of customers. The product was straightforward: a ZIP archive containing 300 English and Latin American Spanish game UI messages, plus JSON, CSV, Godot localization files, a validator, and a commercial license. The awkward part was delivery. A download link alone is useful to a person, but an agent also needs to discover the product, inspect the price, pay, and retrieve the res...
