This is a submission for Weekend Challenge: Passion Edition (#weekendchallenge #devchallenge #ai #googleai #gemini #webdev #showdev) What if your GitHub could roast you harder than your teammates ever would — and then remind you why you keep building? What I Built 🔥 roaster0 — an AI that roasts your GitHub profile, then redeems you. Drop in any public GitHub username and it pulls your real repo data — commit habits, abandoned projects, lazy repo names, language choices — and turns it into a savage, hyper-specific roast using Gemini's structured output and multimodal reasoning. Then it ends with one sincere, earned compliment pulled from something genuinely good in your data. The idea started from a simple thought: your GitHub is an involuntary diary of what you were obsessed with. The eleven repos with no description. The final-v2-FINAL commit. The side project you lived and breathed for three weeks in March before abandoning it. That's passion — messy, obsessive, usually invisible unless someone points a spotlight at it. There's also a second mode, 🎭 Roast Anything : submit a name, bio, links, and/or images, and Gemini reads all of it — text, links, photos — to generate the same experience for anyone, not just developers. Demo 🔗 Live app: roaster0.netlify.app Try it on any public GitHub username, or switch to Roast Anything mode and paste in a bio + an image to see the multimodal analysis at work. Once your roast is generated, you can: 🔊 Listen to it — full audio narration via Web Speech API, paced and pitched differently depending on roast intensity 🖼️ Download the card — every roast renders as a shareable PNG on HTML5 Canvas, ledger-paper aesthetic, ready to post 📋 Share the record — copy a formatted text version straight to clipboard for any platform A couple of examples from testing: GitHub mode — roasted DEV's own founder using nothing but his real public repo data: (screenshot: Ben Halpern roast card — graveyard count, repo names like oceanic-giraffe and test

Title: Week 13: a second team is now running an AI agent on atomic HTLC swaps. Here is what that validates. Tags: mcp, ai, cryptocurrency, blockchain For most of this spring, the map of the agent economy had a strange gap. Wallets to hold keys. Rails like x402 to move value. Marketplaces and reputation so an agent knows who to trust. And then, at the exact moment two parties settle a trade, a custodian: an escrow contract, an evaluator, a referee holding the money while a decision gets made. We have spent thirteen weeks arguing that the settlement layer does not need a referee, because a hash-time-locked contract can hold neither side and still guarantee the trade. This week, a second team shipped a live agent that makes the same argument in code. That is worth stopping on. The signal that mattered this week KaleidoSwap released KaleidoAgent, described as a self-sovereign trader agent on Bitcoin Layer 2s. It is fully non-custodial. It runs a Lightning and RGB wallet, executes atomic HTLC swaps on the KaleidoSwap DEX, runs DCA and portfolio strategies, manages Lightning channel liquidity, and acts as an interactive wallet assistant. The reasoning layer is an LLM (Claude or OpenAI) driving the kaleido CLI and the wallet primitives underneath. Read that list again through a settlement lens. An autonomous agent, deciding what to trade, and executing the trade over a primitive where no third party ever holds the funds. That is the exact shape of the thing we have been building. Different network, same bet. Why the mechanism is the same KaleidoSwap earlier completed what it described as the first atomic swap of an RGB asset on the Lightning Network mainnet, using tUSDT, an RGB20 version of USDT, over real Lightning channels. The detail that makes it atomic is the one that makes every HTLC atomic: The payment hash remains identical across both legs of the swap. Paying the wrapped invoice creates a Hash Time-Locked Contract in the Lightning channel, and the HTLC locks the p

Auth0’s direction is clear: new extensibility work should be built with Actions, not Rules. Auth0’s docs recommend migrating existing logic step by step, converting pieces of Rule code into Action code, testing in staging, and then rolling out one piece at a time. The platform also highlights that Actions give you modern JavaScript, inline documentation, richer type information, and access to public npm packages. I recently looked at the migration path with one question in mind: how do you move from “old but working” to “clean, testable, future-proof” without breaking login flows? This post is the practical version of that answer. Why Auth0 moved from Rules to Actions Rules were Auth0’s earlier customization layer for authentication flows. Actions are the next-generation extensibility platform, built to replace that model with a more structured developer experience. Auth0 positions Actions as a unified environment with version control, debugging, caching, Node 18 support, and access to millions of npm packages. The biggest shift is not just syntactic. Actions use a modern, promise-based programming model and are organized around triggers such as Post Login. That means you are no longer writing the same kind of callback-style Rule you may have used before; you are moving into a more explicit and modular workflow. The mental model change A Rule usually looks like this: it receives user , context , and callback it runs in a broader authentication pipeline it often mixes business logic with token customization, user metadata updates, and side effects An Action, by contrast, is built around a trigger such as onExecutePostLogin , and it receives an event object plus an api object. Auth0’s migration guide explicitly recommends converting Rule code into Action code in stages rather than copying everything at once. That one change matters because it forces you to separate concerns: what is read from the event what is changed through the API what should happen in this trigger
