I made a tool for applying color schemes to websites

I've been working on colorscheme-webify, a small project that makes it easier to apply popular color schemes to websites with CSS. The idea is simple: instead of manually recreating a color palette every time, you can use the project to give a website a consistent color-scheme-based look. GitHub: https://github.com/wak6817/colorscheme-webify I'm still working on it and would really appreciate feed...

D4：線畫在 262，它真的砍了：阿富第一次停損出場

8 月 14 日早上 9 點 51 分，鴻海的零股報價從盤中低點 260 元反彈，回到 262 元。262 正好是阿富前一天晚上覆盤時寫下的停損線。 這是整個實驗到目前為止最誘人的一刻。價格跌破過線，現在彈回來了，任何一個抱著虧損部位的人都會想：「你看，止跌了，再等等。」 阿富沒有等。9 點 52 分整，它先留下一筆看空預測（信心 0.55，預估價格區間 254 到 263，下週一收盤對答案），兩秒後送出賣單：4 股鴻海，限價 261.5。三秒後成交，成交價 262.5，比它掛的限價還好一點，收回 1,050 元。它在下單理由裡寫得很白：盤中最低 260 已經明確跌破停損線，現在只是反彈回到線上；依照規則，停損以事先寫好的線為準，禁止臨場重算，也禁止用「反彈了」當作不執行的理由。 這條規則有來歷。這 4 股鴻海是 8 月 12 日追 AI 伺服器題材買進的，成本連手續費約 1,060...

How can I validate a multi-step Passport form with different required fields based on the application type?

I’m working on a multi-step Passport Appointment form at https://dfapassportappointmentt.com/ built with JavaScript. The form collects information such as application type, personal details, branch, appointment date, and time. The required fields are not always the same. For example, a new application, renewal, and lost-document application have different required fields. The problem is that when ...

AI Agents Just Crossed an Uncomfortable Line

AI agents are getting really good at doing things on their own. And honestly, that's both exciting and a little scary. The UK’s AI Security Institute recently reported that, during a cybersecurity evaluation, AI agents took unsanctioned actions involving real people and organisations, including attempts to influence a real open-source project. That's quite different from the usual: "The AI ge...

Close the Loop Before You Open a New One

Ten things started is not progress. It's ten open tabs in your head, each one costing rent. Every unfinished task keeps a little of your attention hostage. You feel busy. You are just fragmented. Finishing one small thing returns more energy than starting three. So close the loop. Merge the PR. Send the message. Delete the branch. An empty background is where good work actually happens. Done...

EverShop 2.2.1: our biggest release since 2.0 — page builder, metafields, and React 19

We just shipped EverShop 2.2.1 — the largest release since 2.0. It folds in the React 19 work that had been sitting in an unpublished 2.1.3 branch and stacks four months of development on top of it: a visual page builder, a blog module, entity custom fields, a multi-language storefront with a translated admin, a rebuilt shipping and fulfillment stack, built-in cloud storage, product recommendation...

We Almost Deployed a Temporal Knowledge Graph. The Eval Said No.

The eval that killed the temporal knowledge graph asserted one thing: at time T, the agent should report the state that was true at T. It failed 41% of the time. The graph had the right facts. It just handed the agent the wrong one. That number is what saved us from shipping. Every static retrieval metric looked fine. The graph answered "what is the status of Node A" with a confident, well-formed...

Website Load Testing Guide: Test Performance at Scale

If you’ve managed web servers or applications for any length of time, you’ve probably seen this happen: a new feature or campaign goes live, traffic suddenly spikes, and Website Load Testing becomes critical when your website starts returning 503 errors at exactly the moment you need it to perform. What happens next is usually a scramble, SSH into a server you haven’t checked in months, inspect r...

Why French Sound Inventories Differ — and How We Published a Bounded 35-Sound Learning Dataset

When a language-learning product says it teaches “the sounds of French,” one deceptively simple question appears immediately: how many sounds are there? There is no useful answer without first defining the job the inventory is meant to do. A phonological analysis, a pronunciation dictionary, a speech-recognition system, and a beginner curriculum can all model French sound structure differently wi...

How Much Should We Trust AI-Generated Tests?

While exploring X360 AI Tech, I started thinking about something beyond just generating test cases-how much should we actually trust them? Creating a basic happy-path test with AI seems pretty easy, but things like business logic, edge cases, and whether the test is actually checking the right thing still need a human eye. I’m also wondering about what happens a few months down the line. The app...

Content Security Policy in the Next.js App Router: Field Notes on Nonces, strict-dynamic, and the Middleware That Made Every Page Dynamic

Headline: A Content Security Policy (CSP) is an HTTP response header that tells the browser which script, style, and connection sources a document is allowed to use, and in the Next.js App Router the only script policy that survives the framework's runtime chunk loading is a per-request nonce combined with 'strict-dynamic'. The cost I did not budget for: generating that nonce in middleware.ts and...

Ever encountered a race condition bug when fetching data, let's understand the solution

We have all been there before. We build a sleek interface, wire up our API endpoints, and test the application under ideal local development conditions. Everything seems blazing fast and silky smooth. Then a real user opens the application on a spotty mobile connection, clicks rapidly between navigation tabs, and suddenly the screen displays completely wrong information. We refresh the page, try t...

Context Windows Are Not Memory

Everyone is racing to make AI smarter. Almost nobody is asking what it's allowed to remember. I'm starting a daily series on the least understood layer in AI. Day 1. Here's the confusion at the center of it: we've started calling the context window "memory." It isn't. A context window is a desk. You pile things on it, you work, and at the end of the session someone clears the desk. Bigger model...

SMS, chamada de voz ou app: como escolher o método de 2FA certo pro seu produto

Toda vez que alguém pergunta "qual método de autenticação em duas etapas eu devo usar", a resposta padrão que circula por aí é "TOTP é mais seguro, use sempre". Tecnicamente correto, mas incompleto. Segurança não é a única variável que importa quando você está desenhando um fluxo de autenticação — taxa de conversão, custo operacional e alcance geográfico do seu usuário pesam tanto quanto, e ignora...
