I made tool that let's you see everything about any website2024 · v1.web-check.xyz · ▲411Yes, it's open source: https://github.com/lissy93/web-check :) Why I'm building this? There are a lot of tools out there for discovering meta and security data relating to a website, IP or server. But currently, there isn't anything that does everything, all in one place and without a paywall/ user sign up. It's still a WIP, and I'm working on a new version, with some more comprehensive checks, so any feedback would be much appreciated :)

http://webscanner.tk/quickscan/ Hi! I made this project over the couse of a week to help teach myself more about Django and web app development. I am studying computer security in school and web security is one of my passions. It is a tool that helps web developers ensure that they have implemented helpful security mechanisms like HTTPOnly flags, X-Frame-Options, etc. There are hundreds of tools that offer to scan websites for things like cross-site scripting, mySQL injection, etc. This tool simply looks for information that is available via one or two GET requests (the headers, protocols,…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
