Every plugin in this category tells you it reduces context cost. None of them let you check on your own code first, so I built the page that does, and it is the first thing chamnan 1.23.1 ships. arcticfox2029.github.io/chamnan-measure Paste a public GitHub repository URL. The page downloads the so
Welcome to part one! This is the start of a series where I’ll be posting about my webdev and HTML nightmares. I hope you enjoy the read as much as I hate User Interfaces! Consider this a shared space for learning—I’m sharing what I’ve learned so far, and I’d love to hear your thoughts or better so
I had a table in the database that was supposed to fill itself. Its job was to learn from failures: every time the system tried a variant of something and it didn't work, it saved it, to recycle later in another context where it might. A laboratory of failed attempts, piling up. In production it ha
When I started building TokenPulse as a Manifest V3 extension, I knew MV3 was stricter than MV2. I did not know how many things would break silently, produce cryptic errors, or fail only in production. Here is every significant MV3 problem I hit and how I fixed each one. Problem 1: Inline
Short answer: choose an SMS-first authentication messaging API with direct OTP start and verification calls when you own the login templates and need US/EU delivery; keep email as an application-managed fallback, and choose a managed multichannel verification product instead if SMTP relay, voice, Wh
How to distinguish wallet rejection, submission failure, on-chain execution failure, and a STON.fi refund without showing users the wrong status. A failed STON.fi swap should not be handled as one generic exception. In an app, the failure can happen while you simulate the trade, build the transacti
Short answer: Use a split JWT verification architecture: bounded JWKS caching for ordinary API calls, then session introspection only when current server-side state matters—account recovery, credential changes, and other high-risk transitions. For a media product wiring Google and GitHub sign-in, t
Introduction Reactive GUI frameworks have long promised dynamic, responsive layouts that adapt to changing content and screen dimensions. However, the reality often falls short: developers grapple with rigid layout systems that struggle to handle complex constraints, such as linking the height of
asking because I've got a chunk of auth logic at work that I basically wrote and maintained solo for two years. not by design, just kind of evolved that way. started getting nervous about vacation coverage and eventually wrote a doc for it but the doc got stale within like a month. curious how other
Every developer does it at least once a week: you get an unformatted 2MB payload from an internal endpoint or a complex regex string from a colleague, and you throw it into an online web formatter or tester. The problem? Most top search results for "JSON formatter" or "JWT debugger" are laden with
The Repository Pattern post said, more than once, that BookReservationService was "genuinely unit-testable with a mock," because it depends on IBookRepository, an abstraction, rather than a concrete class talking directly to a real database. That claim was never actually backed up with a real test.
Technical considerations in the design of the Obra shadcn/ui kit Thursday this week, Figma released the opacity within variables feature, which allows authors to use an opacity percentage while keeping a color bound to a variable. We have been looking how to implement this correctly in our kit. A
The restartable sequences feature is one of the stranger corners of the kernel's user-space interface; it provides a way for user space to carry out simple lockless operations and be informed if it is preempted over the course of an operation (and must, thus, restart). Work merged in the 6.19 relea
I built EditTextImage, a small AI tool for one specific task: replacing visible text inside an existing image. The idea came from a familiar annoyance. You have a screenshot, poster, product graphic, or social image that is almost right, but one date, label, price, or typo needs to change. Recreati
A browser-side chaos-testing tool that installs a Service Worker to intercept requests across every controlled tab and apply latency, failures, throttling, rate limits, and mock responses without changing app fetch calls (similar to MSW). It uses the same middleware configuration model as chaos-fetc
You open a hotel page. It looks like one product: a search grid, a featured stay, local highlights, reviews, a sticky trip summary. Under the hood it is eight HTTP servers and three UI runtimes. That is the experiment behind HarborStay, a demo booking app I built to answer a stubborn question: C
Here's what I found: most of the advice floating around is either outdated, wrong, or only applies if you're trying to impress other developers instead of getting hired. Let me break down the three biggest lies. Lie #1: "Your Portfolio Needs a Modern Stack" This is the most pervasive
In the previous article, [Java Memory Model: How Multithreading Changes the Rules], We saw that when multiple threads execute concurrently, understanding the Java code alone isn’t always enough. We also need to understand how threads interact with memory—and what guarantees the Java Memory Model pro
Caddy, nginx and Apache httpd each serve static files, terminate TLS and reverse-proxy to a backend. They differ most in the configuration language, and in how much of the configuration has to be written at all. The versions used are Caddy v2.11.4, nginx 1.31.3 mainline and Apache httpd 2.4.68. Eve
For weeks, the saved-articles feature in one of my side projects worked fine. useState held the list, a save button pushed to it, a sidebar rendered it. Every manual test passed. Then a user reported that saving an article in one tab made it vanish from the sidebar in another tab — and sometimes an
