    IPDetective – An API for IP bot detection2022 · ipdetective.io · ▲68

    IPDetective collects data from about 60+ different sources such as official cloud provider endpoints and public VPN/Proxy/Tor/Bot net lists. Then aggregates this data into a fast and easy to use API that can be integrated into applications or scripts easily. IPDetective started as a hobby project for my other hobby projects :) and I decided to wrap a simple website around and offer it as a service. Let me know what your thoughts, if you find value in this service or if you have any feature requests.

    IP Guide – Info on IP addresses, Networks, and ASNs2023 · ip.guide · ▲363

    Hey all, wanted to share my recent weekend hack project. I wanted to improve upon the existing space for looking up information about IP addresses and ASNs. The backend is written in Rust and pulls BGP data every 8 hours from the RIPE RIS project to build up a routing table and also adds geolocation information. The frontend is using React and Tailwind. Would love any feedback or suggestions on what to improve.

    A better IP Lookup tool I made2023 · wafris.org · ▲8

    Most other IP lookup tools I've found are mostly just trying to push you to signup for their API, which is fine but less useful if you're just trying to figure out which IP addresses in your log files are from sketchy locations and likely to do bad things to your application. I merged together a bunch of APIs and some of our own honeypot collected data to make something I hope devs and security folks find useful. If you want to try out a "bad" IP, try this one: https://wafris.org/ip-lookup/104.244.72.115

    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…
