WhatsApp is launching usernames: here’s how to reserve yours

WhatsApp is introducing a new way to add and chat with contacts, without having to share your phone number. Usernames will be launching "later this year," in a move to make the communications platform "even more private," allowing you to keep your phone number concealed from people who aren't already in your contacts. Usernames are […]

Friday Fixes: The Fix That Wasn't

Three bugs this month. All three looked fixed before they broke. The date was quoted in 51 out of 52 posts. The model was pinned to a specific version. The upload feature had been working in production for weeks. Each one passed the obvious checks and failed somewhere else. That's the theme for this Friday Fixes: the fix that wasn't. Not bugs that went unnoticed, but bugs where a defense existed and the failure found its way around it. 1. The Unquoted Date, Part Two If this one sounds familiar, it should. I wrote an entire Friday Fixes post about this exact bug class five weeks ago. An unquoted YAML date. gray-matter parsing it as a Date object instead of a string. A crash downstream. Last time it took down /admin/drafts . The fix hardened formatDate() to coerce Date objects before calling .includes() . I verified it. I shipped it. I wrote 2,000 words about it. I moved on. This time it took down the homepage. The symptom: vibescoder.dev loaded for a split second, then flashed to Chrome's "This page couldn't load" screen. Every browser, every profile, every device. The site was completely dead to visitors. The twist: curl returned HTTP 200 with ~900KB of fully rendered HTML. The server was fine. The crash was happening during React hydration in the browser, invisible to any server-side test. The cause: A new post had date: 2026-06-19 in its frontmatter. No quotes. gray-matter parsed it as a Date object. In posts.ts , the code does const meta = data as PostMeta and then spreads ...meta into the return value. The as PostMeta cast told TypeScript the date was a string . At runtime, it was a Date . That Date object flowed through the server component, through the RSC serialization boundary, and into PostListWithFilters , a "use client" component. React couldn't hydrate it. No global-error.tsx existed to catch the crash. Dead page. Why the May fix didn't prevent this: Because the May fix was in the wrong layer. It hardened formatDate() , the function that happened to cras

Of course Meta thinks gambling is the future

Meta is, by and large, a company built on other companies' ideas. It has almost perfected the strategy: wait for a new platform or social mechanic to take off, then either buy or clone it, put it next to Meta's unmatched user base and advertising engine, and watch the money pile up. Well, the next […]
