  1. Show HN: Kage – Shadow any website to a single binary for offline viewing from github.com/tamnd
    226 by tamnd 3h ago | | |

    Article: 22 min

    Kage is a tool that clones websites into offline-readable folders by rendering them in real headless Chrome and stripping out scripts, allowing users to browse the site without internet connectivity.

    Enables offline access to websites, potentially improving accessibility and reducing dependency on internet connectivity.
    • Kage clones websites into folders that can be browsed offline.
    • It renders pages in real headless Chrome, waits for the page to settle, and then strips out scripts.
    • The result is a folder with HTML files that look like the live site but run no code.
    • Users can install Kage via Go or download prebuilt binaries.
    • Features include quick start commands, cloning options, packing into one file, and serving offline.

    Discussion (54): 8 min

    Article: 4 hr 55 min

    Chaosnet is a local network developed in 1975 for communication among computers within one to two kilometers of each other. It operates without centralized control and uses a simple hardware protocol with carrier-sense multiple-access (CSMA) for collision avoidance on the transmission medium, which is coaxial cable. The software protocol includes connection establishment, routing, flow control, and error handling mechanisms such as retransmission. Chaosnet supports various applications including file transfer, interactive terminal connections, and data in different byte sizes. It also features a broadcast facility for locating services or internal communications within the network.

    Chaosnet's design principles and protocols have influenced subsequent local network technologies, contributing to advancements in networking infrastructure and communication systems within localized environments.
