The question My son was on the sofa with his iPad, poking at the live "Predict the Bracket" game — the whole 2026 World Cup knockout tree on one screen, every slot already filled with the crowd's favourite for that match. Tap a match, see who most people think goes through, watch the picks flow all the way up to a predicted champion. He frowned at it. "Daddy, how do they know which team plays which team? The teams aren't even decided yet." He'd caught something real. The little cards sitting in those slots were only predictions — the crowd's best hunch — but the shape underneath them, who-plays-who and where, was already locked in. Months before a single match kicks off. Fair question. The 2026 World Cup has 48 teams in 12 groups (A through L). The top two of every group go through — that's 24 teams. Then, to round it up to a nice bracket of 32, they also take the 8 best third-placed teams . Twelve groups, but only eight of their third-place teams get a golden ticket. "So you don't know which eight until the very end," he said. "But the bracket's already sitting right there on the screen." "Right." "That's cheating." It isn't cheating. It's one of the prettiest little bits of planning in all of sport, and by the end of the afternoon he understood it better than most adults do. We did it with the dining chairs. The setup, first Before the chairs, my son needed to know where these kids even come from. So we did the boring-but-important part first. A football group is a handful of teams who all play each other. When it's done, the best go forward, the worst go home, and — this is the bit that matters — there's a kid right on the line: the best of the rest , neither safely through nor clearly out. That borderline kid is the star of this whole story. Call them a wandering kid . To learn the trick, let's make the groups nice and small: two groups, A and B, three kids in each — six kids total. In each group the top kid goes straight through to the next round, the bottom ki

Everyone hits the same wall with Claude Code. You add a rule to CLAUDE.md . It works. You add ten more. They mostly work. You add forty more — and now Claude is cheerfully ignoring the rule you care about most, the one that's been sitting there since day one. So you make it LOUDER , in caps, with three exclamation points. It still gets skipped. The instinct is to write more. The fix is almost always to write less . Here's why, and what to do instead. Instruction-following has a budget, and you're overdrawn This is the part most CLAUDE.md guides skip. Frontier models reliably follow on the order of 150–200 instructions at once — and adherence to any single rule drops as you stack more on top of it. It isn't a cliff; it's a slow tax. Every line you add makes every other line a little less likely to be honored. Now subtract what you don't control: Claude Code's own system prompt already spends a chunk of that budget before your file is even read. So the working budget for your project rules is smaller than the headline number — and a sprawling 300-line CLAUDE.md isn't 300 rules followed, it's maybe the first 150 followed well and the rest treated as ambience. The mental model that fixes everything downstream: CLAUDE.md is a budget, not a wishlist. You are not writing documentation. You are spending a scarce attention allowance, and every line competes with every other line. The test for every line: would you bet $5 it's followed? Go through your file line by line and ask one question of each rule: would I bet money this fires every time it's relevant? Three outcomes: Yes, and it's load-bearing — keep it. This is what the budget is for. Nice to have, but I wouldn't bet on it — cut it, or move it to a referenced file (below). It's diluting the rules you would bet on. It absolutely must happen every time — then it doesn't belong in CLAUDE.md at all. Make it a hook. That third category is the one people get wrong, so let's be concrete about it. Advisory vs. deterministic:

I've been building agent workflows for a while, and one capability keeps coming up that the ecosystem hasn't fully reckoned with: letting an AI agent publish a document to the public internet and hand someone a link. It sounds trivial ("save HTML, return a URL"). It isn't. The moment an autonomous agent can mint a public link, you've handed it a primitive that touches access control, data exposure, and reputation. This post is about the design questions that surface once you take that seriously, written by someone who builds in this space. Disclosure up front: I work on Thryvate, a document-sharing tool with an MCP server. More on that at the end, but the problems below are general. The naive version The first version everyone writes is a tool that takes content and dumps it to object storage behind a public CDN URL: publish(html) -> https://cdn.example.com/a8f3c2.html Ship that and an agent can now share its work. It can also now: expose a half-finished draft to anyone who guesses the URL, leave that URL live forever with no way to pull it back, publish something containing a customer's name with zero record of who saw it. For a human hitting "publish" deliberately, those are acceptable defaults. For an agent doing it as one step in a longer plan, they're landmines. What "publish" should actually mean for an agent A few properties turn the naive primitive into something you'd trust an agent to call: 1. Default to private, opt into public. The safe default for an agent-minted link is not "world-readable." It's "only people on this list" or "only people with the password." Public should be an explicit parameter someone has to set, not the fallback. 2. Revocability. Anything an agent publishes, you must be able to un-publish instantly. A live link is a liability with a half-life, and the ability to revoke is what makes it safe to let the agent create them liberally. 3. Expiry as a first-class field. "This link dies in 7 days" should be a parameter on the publish call,

Hello, I'm Maneshwar. I'm building git-lrc, a Micro AI code reviewer that runs on every commit. It is free and source-available on Github. Star git-lrc to help devs discover the project. Do give it a try and share your feedback. A single honeybee has exactly one move: find nectar, fly it home. Impressive aviation. Add a few thousand more bees and something strange happens. Now they're making honey, cooling the hive, and defending the colony against threats ten thousand times their size, with no Jira board, no standup, and nobody handing out tickets. That jump from "can fetch nectar" to "runs a self-regulating honey factory" is the best mental model I've found for multi-agent AI systems . So let's steal it xD First, what even is an "agent"? Before we throw thousands of them at a problem, it's worth pinning down what one actually is. An AI agent is an autonomous system that performs tasks on behalf of a user (or another system) by designing its own workflow and using available tools . Three things decide how good an agent actually is: The LLM powering it i.e the brain. Its tools which is the hands. The reasoning framework is how it turns tool outputs into the next decision. A single agent is fine. It's our lone bee, and it can do real work. But ask it to research a topic, run heavy calculations, scrape five websites, and write the summary, and you start to feel the ceiling. Multi-agent systems: bees, but for compute A multi-agent system keeps each agent autonomous but lets them cooperate and coordinate inside a structure . The magic isn't any single agent, it's the choreography between them (claude which is famous for that). And there are a few classic ways to choreograph it. 1. The decentralized network (a.k.a. "everyone's a peer") Every agent can talk to every other agent. They share information and resources, and they all operate with the same authority . No boss. Just message-passing. This is your agent network . It's great for emergent, collaborative problem-solv

AI can now scan major open-source projects and surface a batch of real, exploitable vulnerabilities in a single pass. That's a defensive win — until you remember attackers have the same tools. Anthropic, Google, Microsoft, OpenAI, AWS, and 15 other organizations aren't waiting for that race to get worse. On Thursday they launched Akrites under the Linux Foundation — a coordinated body built specifically for AI-era vulnerability discovery, remediation, and disclosure in critical open-source software. What actually changed A shared Security Incident Response Team (SIRT) replaces the fragmented model where multiple orgs independently scan the same libraries, file duplicate CVEs, and bury maintainers in noise Patch first, publish second — findings are held under strict confidentiality until a fix is ready and tested Fallback maintainer coverage — if a project has no active maintainer, Akrites steps in so fixes still reach downstream users Funded by Alpha-Omega , an OpenSSF project with $7M+ annual budget backed by the same founding members Three membership tiers — Premier (critical infra operators), General (contributing orgs), Associate (OSS foundations, free) The name comes from the Akritai — Byzantine soldiers who guarded the empire's outermost borders. The places most exposed, most frequently attacked, and most dependent on whoever showed up to defend them. The problem it's actually solving The current coordinated disclosure model was designed around a world where finding vulnerabilities took weeks of expert work. AI has collapsed that timeline. Endor Labs CEO Varun Badhwar put a number on it: thousands of validated open-source vulns surfaced by AI in recent months, with fewer than 5% patched. And the old model makes it worse — every org independently sitting on knowledge of an unpatched flaw is another leak risk before a fix exists. "For years, we have believed finding vulnerabilities was never the hard part. Fixing them was. AI has made that gap impossible to igno

Back in May we here at Waggy Labs launched the beta release of our Web Component UI kit " Yumekit ". Yumekit is a pure web component UI toolkit. Upon its release, it was comprised of roughly 36 fully styled and fully functional UI components that work with just about every web architecture straight out of the box. No configuration or setup necessary, all one needs to do is include the Yumekit script (using either a CDN or installed through NPM) and start building. All components come styled out of the box with no need to include any style sheets. Last week, we launched version 0.5. With this latest release, that job is being made easier with the inclusion of new components that add several layout options as well as new Data, Navigation, and Utility components, bringing the total number of components to 51. For us, this toolkit has provided us a framework-agnostic solution for our internal tools as well as any client projects. With over 60 themes spread over 9 well-known (and some brand new) open source Design Systems all built directly into the library, we have plenty of options available to us to keep our designs fresh without needing to spend hours dealing with CSS. It's light-weight, dependency free, and well documented. New in 0.5 Animate The y-animate component allows you to animate entrances and exits for nested components using a few simple configuration attributes. Code The y-code component allows you to display formatted and colorized code, as well as providing a few easy and convenient ways for your users to copy the provided code. Help The y-help component provides a tutorial experience for users of your application with minimal configuration. Simply provide the elements to be highlighted, the messages to be shown, and it handles the rest! Paginator y-paginator provides a configurable set of pagination buttons to help your users navigate through large data sets. Sidebar We had originally included a y-appbar component (which we still do) that had a "Sideba

Your AI is making your content invisible. Not because it writes badly. Because it writes safely . Ask ChatGPT to summarize an article and it will produce a polished, agreeable précis that offends nobody and surprises nobody. The output is technically accurate and completely forgettable. The problem is structural: most people prompt their AI to confirm what an article says, not to find where it fights with the crowd . The result is a feed full of content that agrees with other content, in increasingly fluent prose, at exponentially increasing volume. If you want to be read, you need to stop prompting for summaries and start prompting for conflict. Why Agreement Is the Fastest Path to Obscurity There is a reliable body of research behind why contrarian content performs. Jonah Berger and Katherine Milkman's widely cited study, "What Makes Online Content Viral?" ( Journal of Marketing Research , 2012) , found that content evoking high-arousal emotions — anger, awe, anxiety — is significantly more likely to be shared than content that merely informs or reassures. Agreement is a low-arousal state. Surprise and contradiction are not. This is not a trick to manufacture outrage. It is a structural observation: the human brain is wired to pay attention to pattern breaks. An article that says "AI is changing content creation" registers as noise. An article that says "AI is making content creation worse, and here's the data" registers as a signal worth attending to. The distinction matters because the mechanism is cognitive, not emotional. You are not trying to provoke readers. You are trying to interrupt the predictive pattern they've built from reading a hundred similar articles before yours. The Problem With Generic AI Summarization When you ask an LLM to "summarize this article" or "give me the key takeaways," the model optimizes for coverage and balance. It is trained on human feedback that rewards thoroughness and penalizes controversy. The output tends to be accurate, ne

Imagine this - you rely on data that you download every day from some system to your own. That requires a trip to the server asking for information, and then a trip back with the payload we requested. This seems pretty fast since the internet is fast. But we also know the programming concept DRY (Don't Repeat Yourself). So, can we apply this principle to how we handle the scenario described above, creating something like DRD (Don't Repeat Data)? Well, yes. There is something to handle this, and it's called — Zero Copy . What is Zero Copy? As the name suggests, you are copying zero data, and yet, you are getting it on your system. How is this possible? If you think about it, you'll probably come to the conclusion that we are just opening a window. The data is just out there to be looked at by those who are allowed to. There's no need to bring the same data to different people's windows; we're just keeping the data in one place and making it available to anyone who needs it. What does this mean for ServiceNow? When it comes to Operations Management—dealing with data fetched from different databases (like monitoring data from Datadog or Dynatrace, ERP data from SAP or Workday, or cloud platforms like Snowflake, AWS, or Azure)—copying that data has traditionally been a hassle. We were reliant on sometimes complex ETL (Extract, Transform, Load) pipelines or massive data extracts. This complicated the whole process, consumed a lot of time, and required careful checking of data pre- and post-migration. So how exactly does Zero Copy help us here? Virtual Data Fabric Tables. Instead of copying data extracted from other tools, ServiceNow queries the exact data that is requested. It temporarily holds that data in memory for the user to interact with. During that time, the user can leverage that data for various use cases as required—and once they are done, it's gone. So, what exactly are the benefits of Zero Copy?! No need for data duplication on the destination. No need for d

A full-stack, peer-to-peer coinflip betting game on Solana A full-stack, peer-to-peer coinflip betting game on Solana. Players connect a wallet, create or join on-chain game rooms, and compete head-to-head for 2× the stake. The UI updates in real time over WebSockets, outcomes are resolved on-chain with Orao VRF, and the backend tracks rooms, chat, and match history in MongoDB. I open-sourced coinflip-casino for developers in Solana / Anchor smart contract development . This post walks through what it does, how the pieces fit together, and how to run it locally. Live demo / site: https://www.flip.is/ Why I built this Learn full-stack Web3 game architecture (wallet + program + backend + UI) Study provably fair randomness with on-chain VRF integration Fork and customize a peer-to-peer on-chain betting room model Most tutorials stop at a smart contract or a UI mockup. I wanted a complete vertical slice — wallet flow, on-chain logic, backend state, and a responsive frontend — so you can study or fork a production-shaped codebase. What it does Create a room — Pick Head or Tail, set bet amount, choose SOL or SPL token. Join a room — Browse open games in the live lobby and match against another player. PvP coinflip — When two players are in the same room, the backend triggers on-chain resolution. 2× payout — The winner receives double the bet (fees apply on-chain). Room expiration — Open rooms older than 5 minutes with no opponent are expired and refunded automatically. Portfolio stats — Win count and total games per wallet. Wallet connect — players sign in with a Solana wallet Peer-to-peer rooms — create or join head-to-head matches Architecture at a glance Wallet layer — users connect a Web3 wallet to sign transactions On-chain program — Anchor/Rust logic for escrow, rooms, and settlement Randomness — verifiable flip outcomes via Orao VRF on Solana Real-time layer — WebSocket events push room and flip state to the UI Persistence — MongoDB stores rooms, chat, and historic

Foundations 1.1 Everything is a File Linux's core philosophy: every I/O resource — files on disk, network connections, pipes, terminals, devices — is represented as a file. This means one unified API ( read , write , close ) works on all of them. The kernel manages the actual resource. Your process holds a token. 1.2 File Descriptor (fd) A file descriptor is just an integer . It is a per-process token that refers to a kernel-managed resource. The kernel maintains a table per process called the fd table — a simple array where the index is the fd and the value is a pointer into the kernel. Process fd table: ┌─────┬───────────────────────────────┐ │ fd │ points to │ ├─────┼───────────────────────────────┤ │ 0 │ stdin │ │ 1 │ stdout │ │ 2 │ stderr │ │ 3 │ listen socket (nginx) │ │ 5 │ User A client connection │ │ 6 │ User B client connection │ │ 12 │ backend connection for User A │ │ 13 │ backend connection for User B │ └─────┴───────────────────────────────┘ 0, 1, 2 are always pre-assigned. Application fds start from 3 upward. The fd is meaningless on its own. It only means something when passed to a syscall — the kernel uses it to look up the real resource. 1.3 Socket A socket is the kernel's internal data structure representing one end of a network connection. Created when your process calls socket() . Lives entirely in kernel RAM. Your process nev

One of the hardest things about going freelance as a developer isn't writing code — it's knowing what to charge. Charge too little and you're basically doing a salaried job without the benefits. Charge too much without backing it up and you scare off clients. Most developers I've spoken to either guessed their rate or copied someone else's. Neither is a great strategy. In this article I want to walk you through exactly how to calculate your freelance day rate properly — based on real numbers, not gut feeling. Why Most Freelancers Get Their Rate Wrong The most common mistake is this: taking your old salary and dividing it by 260 working days. That ignores: Taxes (you now pay both sides of self-employment tax in the US) Unpaid days — holidays, sick days, slow months with no clients Business costs — software, hardware, insurance, accountant fees No employer pension or benefits — you fund all of this yourself If you were earning $80,000 as a salaried developer and you divide that by 260, you get roughly $307/day. But that's actually a pay cut once you factor everything in. The Right Formula Here's the framework: Step 1 — Work out your actual billable days A year has 260 working days. Subtract: Public holidays (~10 days in the US) Your own holiday allowance (~15 days) Estimated sick days (~5 days) Non-billable time: admin, chasing invoices, marketing yourself (~20 days) That leaves roughly 210 billable days. Step 2 — Calculate your real income target Take what you want to take home and gross it up for tax. If you want $70,000 net and your effective tax rate is around 30%, your gross target is roughly $100,000. Step 3 — Add your business costs Software subscriptions, hardware depreciation, liability insurance, accountant — easily $5,000–$10,000/year for a freelance developer. Step 4 — Divide by billable days $110,000 ÷ 210 = $524/day That's your minimum. Price below that and you're losing money compared to employment.

getComputedStyle(element).fontFamily returns the CSS declaration: "Hiragino Kaku Gothic ProN", "Yu Gothic", "Noto Sans JP", sans-serif . That's not the font that rendered. It's a priority list. The browser picks the first one that's available and contains a glyph for the character being rendered. For Latin text, this distinction usually doesn't matter — Windows, macOS, and Linux have converged on a small set of common system fonts. For Japanese, it matters enormously. The visual weight, stroke contrast, and letterform style of Hiragino, Yu Gothic, and Noto Sans JP are genuinely different. A site designed on macOS (where Hiragino is the system Japanese font) looks different on Windows (where Yu Gothic is the fallback). Here's how to figure out what's actually rendering, and what I learned building Japanese Font Finder to automate it. Why getComputedStyle Doesn't Answer the Question getComputedStyle(el).fontFamily gives you the cascade result — what the browser received after applying all CSS rules. But it doesn't tell you which entry in the stack was selected. The underlying question is: does this font exist on this system, and does it have a glyph for this specific character? For Japanese, both conditions matter. A font might exist on the system but only cover a subset of kanji (common with CJK fonts that split across multiple files). The browser will use that font for characters it covers, and fall back for others. Canvas-Based Font Detection The classical technique uses a <canvas> element to measure text rendered with each font in the stack: function getFallbackWidth ( canvas , char ) { const ctx = canvas . getContext ( ' 2d ' ); ctx . font = `16px monospace` ; // known-available baseline return ctx . measureText ( char ). width ; } function testFont ( fontName , char ) { const canvas = document . createElement ( ' canvas ' ); const ctx = canvas . getContext ( ' 2d ' ); ctx . font = `16px " ${ fontName } ", monospace` ; return ctx . measureText ( char ). width ; }
