Start with the naive version. It isn’t a strawman – it’s what a checkout looks like before anyone thinks about this specifically. The cart page computes a subtotal, applies a VAT rate, shows a total, and the ‘pay’ button posts that…
I ran a census of the commit history behind pub-trivia.app expecting to find something about the code. I found something about me instead. 87 commits. Two eras, and a 40-day gap between them. Here is the entire vocabulary of the…
Run a scanner against a page and within seconds you may find missing labels, contrast problems, ARIA mistakes, structural issues, and other WCAG-related signals. For developers, that feedback loop is valuable. The problem starts when we confuse: “No automated failures…
A Shopify storefront can look perfectly normal while dozens of things happen in the browser behind the scenes. A typical store may include: If you are trying to understand the store's privacy behavior, checking whether a cookie banner exists is…
How an ongoing systems debate, one token-economics guide, and a few unusually sharp comment threads turned into 1,031 lines of standard-library Python across a CLI and its test harness, a significantly leaner prefix, and an agent that can no longer quietly…
What I actually found was two counters wearing one name. One of them is cheap and resets itself. The other one was quietly counting my own messages. My working theory had been that every failover jump costs a retry, so…
In this deep dive, we walk through the design of a standalone verification engine, analyze the exact mechanics of cryptographic and replay defense, and explore an unexpected infrastructural failure caused by Python's PEP 668 (externally-managed-environment) when dynamic provisioning goes wrong. The…
I told my friends I'd finally pushed my portfolio live. One of them pulled it up on his phone right there on the bench. The header loaded. The grid behind the hero loaded. Then nothing. A big empty screen where…
Description: Python security, screen capture, spring physics, HiDPI and PyInstaller.exe gotchas. 7 tests from shipping 3 no-telemetry Python apps for Windows (ATLOCK, ASNIPP, APIC). Most Python developers can write a for loop, a Flask route and a pandas one-liner. Python experts…
AI coding assistants made something weird happen on my desk in Lomé: I can scaffold a Node API, a React dashboard, and a Flutter screen before my coffee cools. The problem is not speed anymore. The problem is that plausible…
Unit, integration, E2E, contract tests, test data, coverage, and performance/chaos testing.
