I've spent years writing articles — and almost as many years not publishing them. Not because I had nothing to say. I had everything to say. Every time I solved a hard problem or finally understood something deeply — I wrote it down. That feeling of a light turning on after days of confusion? I wanted to give that to someone else. But perfectionism had other plans. Medium. DEV Community. Google Do
GitHub Copilot just got a lot more complicated — and not in a good way. If you tried to sign up for Copilot Pro recently and hit a wall, that's not a bug. GitHub quietly paused new sign-ups for Copilot Pro, Pro+, and Student plans starting in late April 2026. No end date announced. No workaround offered. Just a message and a door that won't open. That alone would be worth covering. But they made t
A few months ago I was thinking about a problem that almost every freelancer and small business owner faces: customers message at midnight asking "are you free Thursday?" and by morning, they've already booked someone else.

At some point I started keeping informal notes on how many prompt revisions it took to get production-quality output. After a few months, a pattern was hard to ignore. For tasks I described in Japanese: 4–6 revisions on average. 1–3. Same AI. Same model. Roughly similar
An SSG benchmark across five React frameworks, from one thousand You're building a marketplace. Or a documentation site. A wiki, Five minutes. Ten. Twenty. Maybe an hour. Maybe a stack trace. You don't know in advance — and the public benchmarks won't tell So I built a benchmark for the gap. Five frameworks in a pnpm workspace, each rendering one dynamic /posts/[id] from a shared deterministic d
TL;DR TestMu wins on price, faster setup, and community support. Use it if you're testing typical apps on phones and web browsers. Pcloudy costs more but tracks 60+ device performance metrics (battery, memory, thermal), supports IoT and smartwatches, is faster to connect, and handles script migration so you don't rewrite tests when switching. Both run parallel tests fine and work with Selenium,
