I built DBT Companion, a free, mobile-friendly web app for exploring skills commonly taught in dialectical behavior therapy: https://dbt-companion.org The main product constraint was brevity without making the material vague. Each skill combines a short explanation with steps someone can follow. Users can also save favourites and use a browser-based diary card. A few implementation priorities were: making the core content usable on small screens keeping navigation predictable making privacy language visible rather than burying it keeping the stack simple with Rails, Hotwire, and Tailwind Diary cards are saved only in this browser's cookies. If cookies are cleared, saved diary cards will be lost. The app is educational, not a replacement for therapy, crisis care, or professional support. I'd welcome feedback on the accessibility, mobile interface, or anything in the privacy wording that could be clearer.

Finding the right API project ideas is one of the fastest ways to turn a thin resume into a portfolio hiring managers actually stop to read. Building and consuming APIs proves you understand authentication, data modeling, error handling, and the kind of real-world messiness that tutorials tend to skip. This list covers eighteen projects ranked roughly by difficulty, from weekend builds to systems worth putting at the top of your GitHub profile. Why API Projects Move the Needle A to-do list app tells an employer you can follow instructions. An API project tells them you can design a system. Every API you build forces decisions about status codes, rate limiting, pagination, and versioning — the exact vocabulary that shows up in technical interviews. Consuming third-party APIs adds a second skill: reading documentation, handling flaky responses, and caching data so you're not hammering someone else's server on every page load. The projects below split into three buckets: building your own API from scratch, consuming an existing API to create something useful, and full-stack projects that do both. Pick a few from each bucket rather than eighteen shallow clones of the same idea. Beginner Builds: Your Own First APIs Start by designing and shipping a REST API before you touch anyone else's data. A personal blog API with endpoints for posts, comments, and tags teaches CRUD operations and basic authentication without much domain complexity. A recipe box API that stores ingredients, steps, and cook times works well because the data model has natural relationships worth practicing on. A habit tracker API, where users log daily check-ins against goals, adds a light analytics layer once you start returning streaks and completion rates. Here's a minimal example of what a habit tracker endpoint might look like in Express: app . post ( ' /habits/:id/checkins ' , async ( req , res ) => { const { id } = req . params ; const { date } = req . body ; const habit = await Habit . findById

Your cron expression can be valid and still never run A cron parser can answer one question— does this have five fields and legal tokens? —while your scheduler needs a different answer: will this job ever run, and will it run when I intended? That gap is where silent cron failures live. A schedule can be syntactically valid, return no parser error, and still be impossible, surprisingly broad, or operationally noisy. Here is a small semantic checklist you can run before deploying a schedule. 1. Check the calendar, not only the grammar Consider: 0 0 30 2 * This has the right five-field shape: minute, hour, day of month, month, day of week. But February has no day 30. A syntax-only validator can label it valid, while a calendar-aware validator should tell you that its approximate frequency is never. That distinction is important in CI: treat a parse error as a broken input, but treat an impossible calendar match as a review failure. Both deserve attention, but they need different messages. The same idea applies to leap days. 0 0 29 2 * is meaningful, but it does not fire in non-leap years. Whether that is correct depends on the job; the validator should surface the edge case instead of silently deciding for you. 2. Be explicit about day-of-month/day-of-week semantics This expression is a classic source of surprises: 0 0 1,15 * 1 Many traditional cron implementations treat a restricted day-of-month and a restricted day-of-week as an OR , not an AND. In that model, the job runs on the 1st, the 15th, or Monday. Someone reading the expression as “the 1st or 15th when it is Monday” will get a different schedule. This is not a universal rule across every scheduler, so check the documentation for the runtime that will execute the job. The useful validation behavior is to warn whenever both fields are restricted and force the author to choose the intended semantics. For example, a lightweight pre-deployment check can start like this: function semanticWarnings ( expression ) {

Headline: Node.js executes TypeScript files directly — node script.ts works with no loader, no ts-node, and no build step — by stripping type annotations at load time. Type stripping is on by default since Node.js 23.6 and ships in the 22.18 LTS release, but it only covers erasable syntax: I enforce that with TypeScript 5.8's erasableSyntaxOnly flag, moved type checking to tsc --noEmit in CI, and left my decorator-heavy NestJS services on their existing build. Key takeaways Node.js runs .ts files natively by replacing type annotations with whitespace, a mechanism called type stripping. It is enabled by default since Node.js 23.6 and in the 22.18 LTS release; on Node 22.6–22.17 it sits behind --experimental-strip-types . Type stripping handles only erasable syntax. enum , namespace with runtime code, and constructor parameter properties need the separate --experimental-transform-types flag. Node.js never type-checks and never reads tsconfig.json . The type checker is still tsc --noEmit , run in CI or a pre-commit hook. TypeScript 5.8's erasableSyntaxOnly compiler option turns every non-erasable construct into a compile error, which guarantees a file Node.js can run. Relative imports must spell out the .ts extension, and Node.js refuses to strip types inside node_modules — published packages still ship JavaScript. Can Node.js run TypeScript without a build step? Yes, for most application code. Node.js 22.6 introduced type stripping behind the --experimental-strip-types flag, Node.js 23.6 turned it on by default, and the 22.18 release brought the default-on behavior to the LTS line. On Node.js 24 — the current LTS and my daily runtime — node script.ts simply executes. // hello.ts const greet = ( name : string ): string => `Hello, ${ name } ` ; console . log ( greet ( ' Node 24 ' )); console . log ( process . features . typescript ); // 'strip' The mechanism matters. In strip mode Node.js replaces every type annotation with whitespace instead of compiling the file, so l

A few weeks ago I shared nestjs-docfy here — a library that moves Swagger decorators out of NestJS controllers into companion *.controller.docs.ts files, docfy-ui as an AI-first reference UI, and docfy-mcp exposing your API catalog to coding agents via list_endpoints / get_endpoint . Since then the CLI grew a full local dev workflow around the spec itself, and docfy-mcp went from "read the docs" to "verify the API is telling the truth." docfy mock : a server without the server \ shell npx nestjs-docfy mock --spec openapi.json --port 4010 \ \ Spins up a throwaway HTTP server straight from your OpenAPI document — every path returns a schema-shaped response. Useful for frontend work against an API that isn't built yet, or for pointing an agent at something real instead of a static spec file. docfy test : contract testing off the spec \ shell npx nestjs-docfy test --spec openapi.json --base-url http://localhost:3000 \ \ Fires a real request at every documented endpoint and validates the live response against its declared schema. Catches the exact failure mode API docs are famous for: the code moved on, the docs didn't. CI-friendly, non-zero exit on drift. docfy init : zero to configured \ shell npx nestjs-docfy init \ \ One command, scaffolds the docfy-export.ts entry file and wires DocfyModule.forRoot() for you. No more copy-pasting from the README. --link-controller : less boilerplate \ shell npx nestjs-docfy generate --link-controller \ \ Auto-inserts @WithDocs() into the controller so newly generated .controller.docs.ts files are actually wired in — one less manual step per endpoint. Breaking changes, surfaced in the PR itself docfy-pr-check-reusable.yml now runs a spec diff and posts breaking vs. informational field changes as a PR comment. You see the blast radius of an API change before merge, not after a consumer files a bug. docfy-mcp: from lookup to verification The MCP server picked up three tools that turn it from a reference into an actual QA loop for agent

Every time I needed to "compress an image online" or "merge a PDF", I ended up on some site that makes you upload your file to their server. For a random meme, fine. For a contract, an ID scan, or anything private? No thanks. So I built QuickKit — a growing kit of 38 free tools that run 100% in your browser. Your files and text never leave your device. No signup, no watermarks, no tracking of what you process. How it works (the fun part) The whole thing is a static site — no backend, no database, no server cost. Everything happens client-side with browser APIs: Image compressor / resizer → the Canvas API ( canvas.toBlob(type, quality) ) Image → PDF / Merge PDF → jsPDF and pdf-lib, entirely in-page Password / UUID generators → the Web Crypto API ( crypto.getRandomValues ) for real cryptographic randomness QR codes → generated locally, no redirect or tracking baked in Hash generator (SHA-256/1/512) → the SubtleCrypto API Countdown timer & "days since" counters → shareable via the URL itself (state encoded in query params), so there's still no backend Because nothing is uploaded, the tools are faster and more private than upload-based services — and they even work offline once loaded (it's an installable PWA). A few of the tools Files & docs: image compressor, image resizer, image→PDF, merge PDF. Dev utilities: JSON formatter, Base64, hash generator, UUID, timestamp converter, case converter. Everyday: QR generator, word counter, unit/percentage/age calculators, world clock, "your life in weeks". The privacy architecture, in one line If the browser can do it, there's no reason to send the user's data to a server. That principle killed all the usual costs (no servers, no storage, no compliance headaches) and made privacy the default instead of a feature. Would love feedback — especially on tools you wish existed. What "online X converter" do you use that you wish ran locally? 👉 quickkit.space

Two usage-based cloud platforms with different defaults — a CLI-and-primitives approach versus a repo-first, visual-canvas workflow. Here is how they line up as of 2026-07-29. Fly.io and Railway both let you deploy apps and services and pay for what you use, but they start from different defaults. Railway centers on connecting a Git repository and letting the platform read your code and configure the deploy, all viewed on a visual canvas. Fly.io centers on the flyctl command line and a documented catalog of infrastructure primitives, from machines to managed databases and GPUs. This comparison walks through how each platform handles deployment, pricing, databases, networking, and scaling, using each vendor page as of 2026-07-29. Plan details and prices change often, so treat the figures here as a snapshot and confirm the current terms on each site before you commit. At a glance In short Both are usage-based platforms for shipping apps. Pick Railway to connect a repo and let the platform configure, preview, and roll back deployments from a visual canvas. Pick Fly.io for CLI-driven control plus a documented catalog of Managed Postgres, GPUs, Kubernetes, and HIPAA-ready hosting. Pricing and features noted here are as of 2026-07-29.

A finished browser game is a bundle of static files. Whether you built it in Phaser, Three.js, Babylon.js, Godot, or plain canvas code, the output uploads anywhere, which is exactly why the publishing decision trips people up. Every channel accepts the same build, so the choice is never technical. It is about who owns the audience, who owns the money, and who owns the URL. Here is how the three channels actually compare once you have shipped to all of them. The Three Channels Game portals aggregate thousands of titles, monetize with ads, and share revenue. Indie platforms like itch.io act as storefronts you control, with community feedback attached. Self-hosting on your own domain gives you everything except an audience. Most developers who do this well use more than one at the same time. The marginal cost of adding a channel is usually just reading the submission guidelines and wiring up an SDK, so treating them as either/or leaves reach on the table for no reason. What Portals Actually Require CrazyGames reaches over 20 million monthly players and runs a two stage process. Basic Launch takes your game with minimal integration and tests it with a limited audience for around two weeks. Hit their engagement benchmarks and you are invited to Full Launch, which needs the full SDK for ads, auth, cloud saves, and analytics. Their technical bar for Basic Launch is an initial download under 50 MB, fewer than 1,500 files, and PEGI 12 content. Poki is curated and editorially reviewed, leans mobile-responsive, and pulls strong search traffic with a younger audience. GameDistribution syndicates across hundreds of publisher sites through an embed widget, so you get reach but little brand visibility. Newgrounds still rewards experimental work with a community that engages rather than an SDK that monetizes. The trade in all four cases is the same: the portal brings the players, and in return it owns the player relationship and can change terms whenever it wants. Self-Hosting With

Lucide, Tabler Icons, and Phosphor are three of the most recommended open-source icon libraries, and they come up together in almost every "which icon set should I use" thread. All three are permissively licensed, actively maintained upstream, and fully browsable on svgicons.com, so you can compare the actual vectors side by side before committing your project to one visual language. The numbers and license details below are read from the catalog database that powers this site, not copied from marketing pages. Where the sets differ upstream, the comparison sticks to what ships in the indexed releases. Quick comparison Set Icons here License Grid Drawing model Variants Lucide 1,778 ISC 24x24 2px stroke, currentColor One style; experimental icons live in Lucide Lab (373) Tabler Icons 6,143 MIT 24x24 2px stroke, currentColor Outline plus 1,087 -filled icons in the same set Phosphor 9,161 MIT 256x256 Filled paths, currentColor Six weights: Regular, Thin, Light, Bold, Fill, Duotone Three drawing philosophies Lucide and Tabler share a philosophy: a 24x24 grid, geometry drawn as strokes rather than filled shapes, and a default stroke width of 2. Lucide grew out of the Feather community and keeps that restrained, minimal feel. Tabler follows the same conventions but covers far more ground. Because both are stroke-based, an icon is literally a set of lines that inherit your text color: <!-- Lucide arrow-right, exactly as stored in the catalog --> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24" width="24" height="24"> <path fill="none" stroke="currentColor" stroke-linecap="round" stroke-linejoin="round" stroke-width="2" d="M5 12h14m-7-7l7 7l-7 7"/> </svg> Phosphor takes the opposite road. Its icons are filled paths on a 256x256 grid, so the shapes are solid geometry instead of outlined line work. The weight system replaces stroke-width tweaking: instead of making lines thicker, you switch to the Bold cut of the same icon. <!-- Phosphor arrow-right (Regular weight)

This is a submission for Frontend Challenge - Comfort Food Edition, Perfect Landing * What I Built: * I built Ember & Spice which is an interactive landing page celebrating Tandoori Paneer Tikka, one of North India's most iconic comfort foods. The site is built for a fictional restaurant of the same name and brings the dish to life through immersive visuals and interactive features. * The page includes: * A hero section with an aesthetic AI-generated tandoori video A sizzle effect — click the Sizzle button and sparks fly across the image An interactive skewer builder where you stack paneer, peppers, and onions then grill them A spice dial slider that visually changes the marinade heat from Mild to Fiery A CSS-art tandoor oven that roasts your built skewer An ingredient tasting plate — click cards to add items A recipe checklist with a live progress bar A reservation form with client-side validation Fully responsive, mobile-first design with scroll-reveal animations Demo: ** Live site* : https://tandoori-paneer.vercel.app/ **Github *: https://github.com/jogadiyadipak28-art/tandoori-paneer * Journey: * I chose Tandoori Paneer Tikka because it's the kind of dish that carries memory (PS: It's my favorite dish) the smell of charcoal, the bright orange marinade, skewers shared at family gatherings. I wanted the page to feel as warm and alive as the dish itself. The most fun part was building the interactive Kitchen Lab, the skewer builder, spice slider, and tandoor oven are all pure vanilla JS and CSS, no libraries. Getting the tandoor CSS art to glow and the skewer pieces to animate onto the rod was deeply satisfying. I'm particularly proud of the sizzle effect, clicking the button sends 16 spark particles flying across the hero image and story photo, with a brief brightness flash. It's a small touch but it makes the page feel reactive and alive. What I learned: How powerful IntersectionObserver is for scroll-reveal without any libraries. CSS aspect-ratio for keeping the

This is a submission for Frontend Challenge - Comfort Food Edition, Perfect Landing What I Built The Comfort Atlas is a spinning 3D globe of comfort food from ~100 countries. Virtually travel the globe and have a taste of the comfort foods from 100~ countries. Moussaka in Greece, Jollof Rice in Nigeria, Pho in Vietnam. There is also a "featured dish of the day" that rotates deterministically so it's the same for everyone visiting that day. And the fun feature: visitors can type in their own comfort dish and generate a downloadable, passport-stamp-style card in one of three color styles. Demo https://comfort-atlas.netlify.app/ Journey I started with a flat SVG world map, clickable countries, keyboard support, a hover tooltip on the map, all built on real elements so accessibility came for free. It worked fine, but it looked very meh. So i decided to try something i have never done before. Make a globe! I used cobe which promised a 3D globe out of the box. First attempt rendered absolutely nothing but floating dots. 😂 With a lot of the help of my friend claude, we found out that their docs are outdated, and there is not a createGlobe() draws exactly one synchronous frame and expects you to drive a requestAnimationFrame loop calling .update() yourself. Two things on the globe I'm especially proud of, because neither had any library support: a hover tooltip that tracks a marker in 3D space, and a fading "trail" of great-circle arcs between the countries you've visited. Both came down to translating the projection math out of a minified bundle into something readable, then reimplementing it myself. What I would do next: dark mode. What I learned: a lot about accessibility in 3D/canvas, which is so much more difficult than the 2d one, one check for a11y is never enough. Maps are hard, and getting something to track a moving 3D object from regular DOM is even harder. Licensed under MIT Fun fact: I don't like Moussaka, even though i am greek, my comfort food is Pizza. xD

😤 The Problem That Drives Everyone Crazy Ever tried building a Telegram Mini App? Write your code. Spin up ngrok (and pray it doesn't crash). Go to @BotFather, paste the tunnel URL. Grab your phone, open the bot, type console.log() — and pray again. Repeat for every theme, platform, and user type you need to test. It's 2015, folks. And there's still no official emulator. "The main difficulty is the inability to run a project as easily as in a browser via localhost — and the absence of a developer console." — Habr, March 2025 💡 Introducing: TMA DevKit A local emulator and bridge inspector for Telegram Mini Apps. Think Redux DevTools, but for window.Telegram.WebApp. In one sentence: paste your Mini App URL into the panel, and it runs inside an iframe with a full emulation of the Telegram client — no phone, no ngrok, no BotFather. ✨ What DevKit v2 Can Do (and Why It's Awesome) 🧠 MCP Server for AI-Powered Debugging — Brand New!

I spent the last couple of months building Reclaim — an AI job-search agent for engineers, done solo, taking up nights and weekends. It reads your résumé, scores it honestly, and matches you against real open roles. It's live at reclaim.careers (free scan, no signup). This isn't a launch post — it's a breakdown of the stack and, more usefully, the things that broke. Here's how it's built. The stack Frontend — Next.js on Vercel. App Router, server components where it made sense. Vercel for hosting because the deploy-on-push loop is frictionless and I was optimizing for solo velocity, not infra control. Backend — FastAPI on Render. I split the Python backend out rather than doing everything in Next API routes, because the heavy lifting (résumé parsing, the matching pipeline, scraping) is Python-native and I wanted it isolated from the frontend's request lifecycle. Database — Supabase + Prisma. Postgres under the hood. Prisma for the schema and type-safe queries; Supabase for the managed Postgres and some auth-adjacent data. Auth — Clerk. Handles sign-up, sessions, the whole identity layer. More on Clerk below, because it's where I lost the most hours. Payments — Stripe. Live mode, subscription tiers with a trial. Lookup keys drive tier resolution in the webhook so pricing changes don't require code changes. The actual "AI" — Gemini. This is the interesting part, so it gets its own section. Gemini does the real work The thing I care about most: the AI isn't a chatbot bolted on the side. Gemini makes the actual product decisions. Résumé reading: parse the PDF, extract real structure, and score it — not against keyword density, but against whether the claims are substantiated. The whole premise is honesty: most AI résumé tools keyword-stuff to beat the ATS, which backfires the second you're in an interview and can't back up your own résumé. Reclaim does the opposite — it flags where you're genuinely strong and where you're stretching. Matching: scores the résumé against

When you first install WordPress, it is easy to think that every popular plugin will improve your website. After all, the WordPress plugin directory contains tens of thousands of plugins, each promising better SEO, stronger security, faster performance, or beautiful design. That is exactly where many beginners make their first mistake. A new website does not need 30, 40, or 50 plugins. Every plugin you install adds more code that must be maintained, updated, and secured. While the number of plugins alone does not determine performance, unnecessary or poorly coded plugins increase the chances of conflicts, slowdowns, and security issues. Security experts also continue to report that plugins account for the overwhelming majority of WordPress vulnerabilities. The better approach is simple. Install only the plugins that solve an essential problem. Choose one high quality plugin for each task, avoid duplicates, and ignore everything else until you actually need it. Here are the only five to six plugins that most brand new WordPress websites need. The Minimalist Plugin Rule Before installing anything, remember this simple rule: One plugin, one job. If one plugin already handles SEO, you do not need another SEO plugin. If one caching plugin is active, never install a second one. If your hosting company already performs automatic backups, you may not need a backup plugin running every day. Keeping your plugin list small makes your website easier to manage, faster to update, and less likely to develop compatibility problems. An SEO Plugin Recommended: Rank Math SEO or Yoast SEO Every website needs an SEO plugin. Without one, you miss important features such as: XML sitemaps Meta titles and descriptions Search engine indexing controls Schema markup Social sharing previews For beginners, Rank Math's free version includes a generous feature set, while Yoast SEO remains one of the most established and beginner friendly alternatives. Either option works well. The important rule i

If you've ever delayed updating your WordPress plugins or themes because you were afraid something might break, you're not alone. Many beginners avoid updates for weeks or even months because they've heard horror stories about websites crashing after a single click. Others do the exact opposite. They click "Update All" without preparing, then panic when their homepage displays an error or their layout suddenly changes. The good news is that updating WordPress doesn't have to be risky. With a simple maintenance routine, you can keep your website secure, stable, and running smoothly without the fear of losing your content. In this guide, you'll learn how to create reliable backups, update safely, test your website after every change, and recover quickly if something goes wrong. Why You Should Never Ignore WordPress Updates Updates exist for a reason. Plugin developers, theme creators, and the WordPress core team regularly release updates to: Fix security vulnerabilities Patch software bugs Improve compatibility with newer versions of WordPress and PHP Add useful features Improve website performance Running outdated plugins or themes leaves your website exposed to known security issues. In many cases, attackers specifically target websites that haven't been updated. At the same time, installing every available update without preparation isn't the answer either. A single incompatible plugin or poorly coded update can create conflicts that affect your website. The goal isn't to update everything as quickly as possible. The goal is to update carefully and confidently. A Safe WordPress Update Routine Follow this routine every time you update your website. Step 1: Create an Automatic Off-Site Backup Before changing anything, make sure you have a complete backup stored somewhere other than your web hosting account. If your hosting server experiences problems, a backup stored on the same server may not help. Instead, configure automatic backups to services such as: Google Dri

Welcome back to the React Mastery Series ! In the previous article, we explored useEffect Hook and learned how React handles side effects such as: API calls Timers Event listeners WebSocket connections Cleanup operations Today, we will explore two more powerful React Hooks: useRef and useMemo These Hooks are frequently used in production applications to: Access DOM elements Store values without triggering re-renders Optimize expensive calculations Improve application performance Understanding useRef Hook useRef is a React Hook that allows us to store a value that persists across renders without causing the component to re-render. Syntax: const reference = useRef ( initialValue ); The returned object looks like: { current : initialValue } The value is accessed using: reference . current useRef vs useState A common question: Why do we need useRef when we already have useState? The difference: useState useRef Updates trigger re-render Updates do not trigger re-render Used for UI data Used for storing values React tracks changes React does not track changes Example: const [ count , setCount ] = useState ( 0 ); Updating: setCount ( count + 1 ); causes: State Update | ↓ Component Re-render With useRef: const count = useRef ( 0 ); Updating: count . current ++ ; does: Value Updated | ↓ No Re-render Using useRef to Access DOM Elements One of the most common use cases of useRef is accessing DOM elements directly. Example: import { useRef } from " react " ; function SearchBox () { const inputRef = useRef (); function focusInput () { inputRef . current . focus (); } return ( < div > < input ref = { inputRef } /> < button onClick = { focusInput } > Focus Input </ button > </ div > ); } Flow: Button Click | ↓ focusInput() | ↓ inputRef.current | ↓ Input DOM Element | ↓ focus() Real-World Example: Login Page Imagine a banking login page. When the page loads: Open Login Page | ↓ Username Field Automatically Focused Implementation: useEffect (() => { usernameRef . current . focus ();

I shipped a bug into a paid API and it took me a while to see it, because nothing errored. Every response was a clean HTTP 200 with a confident number in it. The number was wrong by 25x . Here is the finding, the arithmetic, and how to check your own code in about thirty seconds. The measurement Uniswap v3, WETH/USDC on Base. Left column is what my API reported as TVL. Right column is what the pool contract actually holds — a plain balanceOf on each token, at the pool address. pool reported actually held overstated uniswapV3 0.01% $2,070,000 $215,646 9.6x uniswapV3 0.05% $73,600,000 $10,069,584 7.3x uniswapV3 0.30% $2,840,000,000 $111,513,855 25.5x uniswapV3 1.00% $14,800,000 $846,661 17.4x $2.84 billion in one pool on Base. Base's entire ecosystem TVL is a few billion dollars. That is what finally made me look — not a failing test, just a number too large to be true. Why it happens A v2 pool holds two piles of tokens and the price is the ratio between them. getReserves() returns the actual piles. Easy. A v3 pool concentrates liquidity into price ranges. It does not have "reserves" in the v2 sense. What it has is a liquidity value L at the current price P , and the standard way to make v3 math reusable is to compute the virtual reserves — the amounts a v2-style pool would need to behave identically right here: x_virtual = L / √P y_virtual = L × √P These are enormously useful. Feed them into the ordinary constant-product formula and you get correct swap outputs and correct price impact, which is why essentially every v3 integration computes them. They are also not tokens anyone owns . They describe the shape of the curve at the current price, not custody. Concentration is exactly the point of v3: a position spanning a narrow band behaves like a much larger v2 pool while holding far less capital. The 25x above is that leverage, showing up as a number I then mislabelled. My code did this: tvlUsd = 2 * reserveA * priceA // fine for v2, nonsense for v3 That line is corre
