Twibright Twig is a static HTML photo gallery software that supports organization of JPEG and PNG images into a directory structure and EXIF and JPEG comments. It is meant for more experienced users rather than newbies. Three levels of downscaled image and three levels of thumbnails are generated. Each image is assigned a unique identifier to faciliate easy random linking from a master Web site. It handles reasonable large galleries (and is currently used for a 3GB one). Automatic regeneration of added, changed, and deleted images can be done with one script.
Galet is a peer-to-peer application which primarily aims to provide easy-to-setup, secure communication channels between the computers of people who know and trust each other. Its secondary goal is to create a public network based on these channels. No direct connections occur between two nodes that have not been explicitly accepted by the users of these nodes. This makes the network very difficult to censor, as an attacker's direct access to the network is limited.
Spana/Panorama is a protocol and a reference implementation for a new peer-to-peer network with the primary goals of providing anonymity and a robust network. Some of the implemented features are: anonymous file transfers (on both ends) and news (NNTP), RSA-based virtual identities for file authentication, advanced file indexing for searching (such as on bit rates), and automatically resumed downloads from multiple hosts using cryptographically strong checksums on files (cf. heuristics based on filenames) for security and flexibility.
