You're in another app and there's a timer counting down at the top of your phone. You lock the screen and the same timer is sitting there. You swipe down to the Notification Center and it's there too, still ticking. It looks like a notification, but a notification can't tick. That's a Live Activity. It looks like three different surfaces (Dynamic Island, lock-screen banner, Notification Center ent
I kept watching the same thing happen. What I Built It's a 3D interactive sales simulator. I call it a flight simulator for software — except instead of flying a plane, you're walking a non-technical client through the risk inside their own infrastructure. The Map You feed it a simple JSON file describing your client's tech stack. It reads it and instantly draws a floating, 3D web of nodes — s
I was building a side project that needed image compression. My first instinct was to look for an API — TinyPNG, Cloudinary, something with a POST endpoint. if (blob.size >= file.size) { Try the requested quality first. If the output is bigger, walk down through lower qualities until something sticks. As a last resort, if WebP output is still larger, fall back to JPEG entirely. Not elegant, but it
Ever had users sign up with [email protected] or [email protected]? Disposable email addresses are a headache for any app that relies on real user contact. I built burner-bouncer to solve this — a zero-dependency libra
I finished an English series on the way I think ordinary people can start using AI for real work. The point is not to become an AI expert first. The point is to have one place where you can say what you want, give the tool access to the right folder, and check the result. Anything important still needs a human pause: publishing, deleting, paying, or authorizing. My preferred starting point is simp
Introduction "All hands on deck for the future of AI-driven development." This is the NO.56 article in the "One Open Source Project a Day" series. Today, we are exploring OpenHands (formerly known as OpenDevin). While projects like RuFlo focus on backend orchestration and cmux on terminal visualization, OpenHands is currently the closest open-source equivalent to a "final form" AI software engi
When you bind Ctrl+S to "save" in a web app, do you check event.key === "s" or event.code === "KeyS"? The honest answer is "I don't remember, I copy-paste from Stack Overflow." Until a Dvorak user reports the shortcut is broken — or a Japanese IME user reports it fires mid-composition. This is a live inspector for KeyboardEvent: press any key (or combination), see every field — key, code, keyCode,
sysctl: setting key "net.ipv4.ip_local_port_range": Permission denied I saw this error while trying to tune the network stack for a high-concurrency service running in Docker, which itself was hosted inside an unprivileged LXC container on Proxmox. The weird part? I was root inside the container. I expected that since I had already enabled nesting=1 and keyctl=1 in the LXC configuration, Docker wo
