btw this is already running on all my machines (including a macbook), and i've configured all of them to have routable public ip addresses ;) especially for the mac, my ISP is SFR (over coaxial connection) with only dynamic ipv4, i can use this to get stable v4/v6 addresses very easily for all my devices behind the router ios/android app soon^{TM} Comments URL: https://news.ycombinator.com/item?id=50141436 Points: 30 # Comments: 7

Even Healthcare reaches a $300 million valuation in a Khosla Ventures-led round as it plans to expand its hospital network in India.

State of the MCP Registry, week of 2026-10-19 by ka, mcpreflight Every Monday we re-scan the whole official MCP Registry with a read-only check. We send an initialize request, then a tools/list request. We never call a tool, never use a credential, never attempt a payment, and never retry a failing endpoint into apparent health. Everything below is reproducible with one open-source command, and the per-server reports and raw JSON are published. Headline Of 9,991 remote endpoints in the o...

I pasted the same MCP server into 4 config files. Then I wrote a tool to clean up the mess. If you use Claude Desktop, Cursor, VS Code, and Codex side by side, your MCP setup is probably a mess. Mine was. The same filesystem server lived in three different config files. One copy had different args than the others. And one entry pointed at a command I'd uninstalled months ago — a dead link sitting there silently. Editing four JSON/TOML files by hand to fix this is nobody's idea of fun. S...

Your agent shipped the upload endpoint. The feature works, the demo works, the pull request is tidy. Somewhere inside it, the filename a user uploads is also a path, and nobody tested that. A benchmark published on October 10, 2026 puts a number on how often that happens. The Last Secure Code Benchmark (LSCBench, arXiv:2610.14766) took 150 real vulnerabilities, expanded them into 450 tasks across seven languages, and handed them to six frontier coding agents. The prompts asked only for functi...

A platform can show funded , approved , paid , or settled . Those labels are not interchangeable. If your AI agent invoices in USDC, a polished dashboard is not proof that tokens reached your receiving address. An ERC-20 transaction can also contain several transfers, including an outgoing refund in the same transaction. Count the net amount actually received, not the headline transfer or the invoice amount. I recently audited a small live Base USDC micro-payment workflow. The useful e...

If you run multi-session agent fleets, you know this smell: git worktree list scrolling past checkouts nobody owns anymore. A session died, its worktree leaked, and now there are six stale branches with names like fix-thing-3 that nobody dares to delete. Multiply by every fleet run and you get a repo full of ghost worktrees. Ben Newton's worktree claim guard (a session-fleet Mod) proved this is a real problem class: sessions racing over the same worktrees. Guards solve it at creati...

I had access to five ChatGPT Pro plans and three Claude Pro plans through referral offers. Ten days later, I had spent more time switching accounts and remembering which project I had left open than using the coding allowance. I wanted one place to describe work, let an available tool take the next step, and review what it actually produced. That became Runquay : an MIT-licensed, local work queue for AI coding tools. It launches the official Codex, Claude Code, Gemini CLI, or Antigravity CLI...

This guide was written with AI assistance as part of NixieFX marketing. This is a proposed integration recipe, not a claim of a completed runtime test. A quest marker should still communicate completion after its particles disappear. Treat the effect as a short acknowledgment of a state change, while the completed icon and text remain the authoritative UI. The sequence in this example is deliberately small: update the quest state, show the completed marker immediately, optionally play one ...

IPv4 Subnetting for Beginners: Step-by-Step Examples and Practice Questions Introduction IPv4 subnetting is an important networking skill for IT students and people preparing for certifications such as CompTIA Network+ and Cisco CCNA. Subnetting divides an IP address range into smaller networks. It helps network administrators organize devices, manage IP addresses, and design networks efficiently. In this beginner-friendly guide, you’ll learn how to identify a subnet mask, ...

Your Semantic Cache Has a Health Problem. Nothing Checks It. Here's the situation: every LLM gateway now ships a semantic cache. GPTCache, LangChain's caches, Redis vector lookup — they all do the same job: store a response, look it up later by embedding similarity, skip a costly LLM call. But they only operate the cache. Store. Lookup. Evict. Nobody diagnoses it. That leaves three silent failure modes running unobserved in production: Cache pollution. A lightly rewritten p...

Your first week on a mobile AI repo usually starts with a task that sounds small: point the app at a different inference backend so you can test without touching production credentials. On a mid-range Android phone in a debug build, with the screen off for thirty seconds and Wi-Fi dropping to LTE mid-request, that "small" task is where juniors either learn the repo or quietly break it. The drill below turns that task into a repeatable swap with evidence, and it fits the first hour, first PR, fir...

Model Context Protocol (MCP) lets AI clients connect to tools and external data sources through a consistent interface. Running an MCP server locally is useful during development, but what if you want to host one remotely? In this tutorial, we'll deploy a Python weather MCP server built with FastMCP to Amazon EKS , expose it through a Kubernetes LoadBalancer Service, and connect it to Claude Code and Pydantic AI Agent . What we're building Our application follows this ...

In the SPF vs DKIM vs DMARC comparison, SPF lists who may send your email, DKIM signs each message, and DMARC tells receivers what to do when a check fails. You need all three. Together they stop others from faking your domain and help your mail reach the inbox. SPF vs DKIM vs DMARC at a glance Each record answers a different question. The table shows them side by side. After it, we explain each one in plain words. Record Question it answers Where it lives ...

The U.S. Department of Energy can order a utility or grid operator to keep running generation under section 202(c) of the Federal Power Act. DOE lists those orders on its website as text. I put every order, extension and amendment from DOE's 2025 and 2026 pages into one CSV (85 rows), with a small standard-library Python script whose tests check the counts against the table. What the table shows, as of 18 October 2026: 66 orders, extensions and amendments in 2026 so far , against 19 in...

Design a CDN: the content delivery network system design walkthrough The request to design a CDN sounds like a one-liner — put the files closer to the users — and that one line hides the whole interview. A content delivery network system design is not a file server with extra machines; it is a globally distributed read-through cache where a request from a phone in Mumbai should be answered by a server a few milliseconds away instead of crossing an ocean to your origin, and where the ha...
