TL;DR: TestSprite is a solid testing tool for developers who need faster feedback loops on UI changes. Its locale detection is powerful, but the timezone handling has gaps. Real-world verdict: 8/10 for internationalization workflows. The Setup I've been shipping apps to 15+ countries, and locale bugs hit production fast. Date formats flip, currency displays break, non-ASCII inputs silently fail, a
5 Lessons I Learned Building a Firefox New Tab Extension from Scratch I spent the better part of a month building Weather & Clock Dashboard — a Firefox new tab extension that shows live weather, world clocks, and a search bar. No frameworks, no bundlers, just pure HTML/CSS/JS. Here's what I wish someone had told me before I started. manifest_version: 3 Transition Is Mostly Smooth, But Watch for
The Problem Nobody Talks About You've shipped your app to 10 countries. Users in Japan complain the date picker shows "13/32/2026". Brazilian users see a price tag formatted "$1.000,00 USD" (technically correct for locale, but weird). Indian devs report timezone calculations are off by 30 minutes. And somewhere in Eastern Europe, a Cyrillic username broke the entire checkout flow. This is locali
The most popular HTML, CSS, and JavaScript framework for developing responsive, mobile first projects on the web.
Introduction Picture two doctors updating the same patient record at the same time - one in São Paulo, the other in London. Both are offline. When connectivity returns, whose changes prevail? This is not a hypothetical. It is the everyday reality of distributed systems: multiple nodes, no shared clock, no guaranteed network. The conventional answer has long been locking - one node waits while an
I've been shipping software internationally for 5 years, and I've seen localization bugs tank launches in ways that make deployment failures look quaint. Currency displays in the wrong locale. Dates that make Japanese users think the app was built in 1970. Phone numbers that break form validation in Brazil. Last week, I decided to actually test TestSprite on a real project instead of adding it to
Bonus chapter — Engineering Intent Series Live demo: dungeon-demo-isl.netlify.app Source: example/dungeon/ in the ISL repository The first four articles of this series argued, from different angles, that LLM-driven development becomes predictable only when you replace prompts with a compilable specification. That is a strong claim, and a small toy app is not enough to defend it. So we built someth
I used two Amazon Bedrock AgentCore capabilities, Amazon Bedrock Registry for hybrid search over 10k+ Kiro resources, and AgentCore Harness for testing generated skills against a real agent, to build an AI-powered skill generator for Kiro Hub. Try it at kirohub.dev/generate. I've been building Kiro Hub for a few months now. The hub has over 10,000 community resources, including steering files, hoo
