Show HN: An MCP server that gives your AI assistant write access to /etc./hostsI was tired of how bad distraction blockers are so I built my own.LockIn lets AI assistants (Claude, ChatGPT, Cursor, etc.) block websites by editing the system hosts file directly via MCP tools (via a secure cloudflare bridge).Why? Because chrome extensions don't work. Blocking it natively makes it unbypassable, and having your agent gatekeep your focus is the ultimate cheat code.Since everyone is using AI agents nowadays, but most people start scrolling or Reddit while waiting for Claude Code to finish, giving them control over your focus solves that.The MCP server exposes four tools: block_site, unblock_temp, focus_session, get_status. A background daemon keeps the state synced and persists across restarts. There's a relay URL for hosted MCP connections (ChatGPT, Copilot).Install: npx -y lockin-mcp installWhat makes it so good for me is the timed unblock: it gives the flexibility most tools miss. If you're studying for school you don't want to be distracted by yt, but perhaps you ha

A fleshed-out IPv5 proposalOver 30 years after its introduction, IPv6 has still not replaced IPv4. I've seen those "just add more bits to ipv4, call it ipv5" proposals before. They tend to skip the important details and talk past others, but they have a point. After filling in the details over time, I think this actually works, it'd make a serious difference, and it's doable with the current IPv6 header.Background...Let's assume the IPv6 packet format is already sufficiently supported on routers, hosts, etc. That's not the blocker anymore, rather plenty of ISPs, web services like Github, and corporate networks have chosen not to adopt IPv6. Home routers just enable it, but it's nontrivial for services because it's a separate network from v4 in every way, requiring extensive config changes. End result, almost everyone needs a v4, while many use v6 but don't depend on it.IPv6 absolutely needed a new packet format to support >32-bit addrs. But it made more choices beyond that, largest of which was starting with a f

Show HN: Make your terminal pulse orange when Claude Code needs inputIt's not always obvious if Claude Code finished because it's done or needs an answer to a question.. Now the tab color will tell you. pulsing orange – blocked on you (question or permission prompt) solid green – finished the turn ⬜ no tint – working Not obvious to me when I started:- Telling a BLOCKING turn ("Which file?") from a CLOSING one ("Anything else?") isn't a regex job (if '?' in answer return BLOCKING). I used a mixed method, with Haiku and rules to optimize for both speed and accuracy.- The pulsing works even if Claude doesn't use a AskUserQuestion prompt.- Using this made the recent very annoying 60 second timeout (https://github.com/anthropics/claude-code/issues/73125) for such prompts less disruptive. I simply run `claude --disallowed-tools AskUserQuestion` and still get prompted by my tab color.macOS + iTerm2 + Claude Code only. MIT. https://github.com/rickardstureborg/claude-needs-input

Tell HN: I'm not excited for Fable and am disappointed in Karpathy* High level reasons:It increases the gap between the rich and the poor. You think indie devs and individuals have the resources to pay per token? The direction Anthropic is taking is one that leads to more inequality, only this time it's intelligence inequality between small and large corps.Anthropic also intentionally crippled the model when it comes to doing AI research. And then Karpathy (an AI researcher who defected to Anthropic) has the audacity to praise the model?These decisions were already made by Anthropic (a company that actively wants AI regulation and banning of open source models) BEFORE the USG request to take down the model, so they can't blame the politics for this.* Earthly reasons:We were originally going to get 100% usage from June 9th to June 23rd (15 days)Instead we got 100% usage for 3 days and 50% usage for 7.And it's nerfed on day 1:> ... we're redeploying the model with a new set of classifiers to target and block more cybersecurity tasks.

Ask HN: Which GitHub features are needed in a code forge before you can migrate?Which GitHub features would you consider a blocker for migrating to a different code forge, and in what order do you prioritize them?Context:I am heads down building a code forge (https://juju.bi) based on three ideas: - Code collaboration part should work offline - Should be compatible with GitHub API (like how some services are considered S3 compatible) - Support `change-id` based features (ex: Jujutsu's evolog) I shipped a super-early version that I am currently dogfooding. https://juju.bi/changelog/2026-07-01-alpha-releaseI am currently focused on improving the experience for small teams working on private repos. I would like to polish the overall product before thinking about public repos. (A lot of great forges exist for public repos right now).

Show HN: AI Agents the Unix Way – built with bash, curl, and jqWhile working on an educational exercise tinkering with local models and trying my hand at setting up agents, I went down a rabbit hole: to see how far I could build a custom agent loop using exclusively command-line building blocks and stripping out dependencies wherever possible.It turns out you can get pretty far with pipes, text streams, append only logs, and standard command-line components - concepts pretty well aligned with classic Unix philosophy. The agent is a wrapper composed of a handful of smaller programs, which should allow for flexibly injecting various tool to inspect, filter, redirect, and audit different stages of the agent loop.This project as it stands is a proof-of-concept, but packs enough punch with tool calling support - which in theory should make it indefinitely extensible. With that said, it does appear that the sophistication of tool calling is largely limited by the underlying model, and so far I’ve only experimented with lightweight local models (e.g. lla

Show HN: Ember, a native iOS Hacker News reader I built around accessibilityI read HN on my phone every day and never really settled on a reader, so I wrote my own and finally tidied it up enough to put out there.It's plain SwiftUI with no third-party dependencies. A few things I spent the most time on:Comments are parsed and drawn as native text instead of being dumped into a web view. Links, italics, quotes and code blocks behave like the rest of the OS, text selection works, and threads collapse instantly. The whole comment tree comes back from the Algolia API in a single request, which felt a lot nicer than walking the Firebase API node by node.Accessibility. Nothing depends on color on its own, so points, read state and selection all carry a shape or an icon too. VoiceOver reads each story as one coherent element with proper actions, Dynamic Type and Reduce Motion are respected, and there's a color-blind mode. The first-run setup actually looks at your device's accessibility settings, switches on the matching options, and tells you what it changed instead

Show HN: F1l0 – Fitness LoggerI build this self-hostable, PWA-ready fitness tracking app.This is less about the app itself, there are probably dozens of them out there. This is more about me being fascinated about the idea of "personal apps": AI enables us to just build something that perfectly fits our indivual requirements - like a tailor-made suit.None of the apps I know matched my requirements, some of them come with a subscription, some required an account. So I build F1L0. It would even work as a static HTML page with no backend services - like on GH Pages. I just needed a backend to add synching support with Firebase.Repo: https://github.com/nickyreinert/f1l0Features:- custom training blocks and excercise of course - custom train/pause routine - simple plain data model that can be exported to ask AI for trainign advice - supplement support - did you take your "meds"? - progress tracker with some simple charts - using Firebase to sync (right now only Google Accounts are supported)If you complain about feature

Show HN: writing tasks with focused context + instructions = sharper AITo get an AI to do a task well, you need to give it the right context and the right task description. I've had a lot of struggles working in a large codebase getting AI to follow the existing patterns and architecture. So I started building a VS Code / Cursor extension that lets you quickly snap together sub prompts/instructions relevant to a specific task. After seeing the value of this, I realized you could make those sub prompts more customizable by using a liquid syntax engine.That worked fine for a few days, until the original context blocks got stale as the project progressed. I wrote an MCP server that can update those blocks, creating a feedback loop. A few days later I added an amend option too, so the AI can write a log and decision record as it goes.At this point I realized there were a lot of opportunities here: my AI isn't spending the first 5 minutes doing research, I've got better control over my context window, there's less irrelevant data leaking in from my agents.md f

Show HN: Satd – a Bitcoin full node in RustI'm Ben, and I've written a modern, independent implementation of the Bitcoin protocol in Rust. The primary problem I wanted to tackle was monoculture: the Bitcoin network and community has been based on a single C++ implementation for 15 years, a descendant of the original Satoshi-authored codebase. This codebase and the small Core committee are a single-point-of-failure, and is a potentially attractive target for those who would seek to damage or disrupt the network.On top of that, while the Core team has done a great job at stewarding and improving the codebase, it can't help but be a big, complex tree of largely legacy C++. I wanted something modern, easier to maintain and with batteries included:- Native TLS (including mTLS) out of the box- Built-in (optional) API services for Electrum (based on electrs) and Esplora (no sidecars or separate services needed to run a wallet backend)- Atomic indices with a single RocksDB data store (address index can't lag core block index, for examp

Show HN: AwsmAudio – a WebAudio editor with native MCPHey y'all,So - the main idea of this is to make a WebAudio synthesis/sequencer tool which humans can use via the UI, but where the big unlock is for agents to drive with MCPIt's semi decent as "make a groovy jazz track", especially for retro sounds - but the real use case is more like "make a jetpack whoosh effect I can control via code at runtime - where the sound changes based on character health or how much fuel is left"In other words, the target audience is not musicians (except maybe of the Max/MSP sort), but more like creative coders who want to shape the sound iteratively with an agent, and then use and _drive_ in in a game/simulation.Fwiw I think this approach is going to be more and more... and I'm working on a renderer/editor tool too (will share separately when ready). What I mean is, there's a lot of "block box" AI tooling out there, and a lot of "add MCP to existing tools", but building new tools where humans get one experience and MCP exposes another layer really just for

Ask HN: I Need Help for a ProductI have a very high-quality SaaS product that's ready to launch. Everything is complete: the product, testing, LLC, bank account, Stripe, tech stack, etc. But I built it as a programmer trying to create the coolest thing possible for a product I've always wanted to make. My issue is that using Claude as a lawyer is scaring me. What I consider moral and what seems to be legal are two different things. For context, the product uses an AI pipeline to adapt user-provided content into dramatized formats. Think of it as ebook-to-graphic-audio adaptation (though there are other pipelines). The quality is insanely good, but having users bring copyrighted content they own to be adapted is legally unclear. ElevenLabs doesn't add sound effects, so they're fine, but this involves transcription plus additional steps. Claude's legal responses are also scaring me. Even with aggressive content moderation to reject CSAM-related materials, report to authorities, block users, and include it in the ToS, th
