Unix timestamps are everywhere. APIs, databases, logs, JavaScript and authentication tokens all use them, and they cause a surprising number of bugs. Is 1790186400 a date? What about 1790186400000? Does a Unix timestamp…
i'm om yaduvanshi, 18. i build ai agents, and my second project is cloudline — website analytics without cookies. the problem: i put GA4 on a side project, added the cookie banner the lawyers want, and watched a chunk…
Originally published on NextFuture iOS 27 mang Apple Intelligence for Home tới HomeKit Secure Video, đổi thông báo "phát hiện chuyển động" thành một câu mô tả cảnh. Apple tính tới 9,99–59,99 USD/tháng cho tính năng này,…
Originally published on NextFuture PR đang mở, CI xanh, diff 400 dòng do agent viết và cũng do chính phiên đó tự review. Bạn kéo qua một lượt, thấy hợp lý, bấm merge — lần thứ mười trong tuần. Bài này dựng cái cổng đứng…
Laya is an open-source, 421M-parameter System 1 decision model that answers typed questions in 32.8 milliseconds on a T4 GPU and costs nothing to host. Fine-tuned on a shared benchmark, it edges TypeSafe's closed Jev…
Part IV showed a WebMCP page with three tools. The companion walked through building one yourself, the JavaScript way: registerTool(), a schema, a handler. It mentioned the other way in one sentence and moved on. This…
Originally published at getnobody.org. A lot of forms still arrive as flat PDFs: an intake form, a volunteer application, an order sheet. Nothing on them can be typed into, so people print them, fill them in by pen and…
A "servings" slider looks like the easiest feature on a recipe site: multiply every quantity by a factor. Then you ship it in Polish and discover two things — scaling has real-world edge cases, and Polish has three…
When a site grows past a few hundred pages, category browsing stops being enough. People want to type "t rex" or "unicorn easy" and get results instantly. The usual answer is a hosted search service — but for a static…
A trivia quiz looks like the simplest app imaginable: show a question, show four options, check the answer. But the details decide whether it feels fair — and whether a room full of students (or friends at a party)…
I got tired of paying $50/month for API tokens and sending my data to servers I don't control. So I built LocalMind — a lightweight AI agent framework that runs entirely on your own machine via Ollama or WebGPU. No API…
Most chains let anyone push a token balance into any address for free. That is why "holders" is a nearly meaningless metric almost everywhere — an airdrop to 100,000 addresses costs the sender gas and nothing else. The…
Text-to-image tools are a fun canvas project with a surprising number of gotchas: fonts that haven't loaded yet, text that overflows, effects that "flicker" on every re-render, and clipboard APIs that behave differently…
"Just generate 20 random addition problems" sounds like a five-minute job. Then a teacher asks for problems with regrouping only, a parent wants to reprint the exact same sheet next week, and someone notices the answer…
Online file converters traditionally upload your file to a server, convert it there, and send it back. That costs the operator bandwidth and compute, and it means users hand over their files to a stranger. Videozify…
LeveloJS Went Quiet. We Were Rebuilding the Foundation. It has been almost a month since we shared a major update about LeveloJS. If you have been following the project, you may have noticed that we have been unusually…
We run a pay-as-you-go proxy service. Until this month, using it in a browser meant the manual route: open the proxy settings, type a hostname and port, build a username by hand, sign in at the 407 prompt, and repeat…
Daily challenges are one of the simplest engagement features you can add to a games site — Wordle made the pattern famous. On Classroom Games, a collection of free learning games for teachers (math, typing, spelling,…
Teachers have a very specific set of constraints that most web apps ignore: locked-down district Chromebooks, no permission to install anything, strict student privacy rules, and about five minutes between the bell and…
This article was originally published on the Notepad Neo engineering blog. Notepad Neo is a free online notepad that runs entirely in the browser, with no account and no server, so every export has to be generated…
