Cloud Torrent
Cloud Torrent, a self-hosted remote torrent client
Cloud torrent is a a self-hosted remote torrent client, written in Go (golang). You start torrents remotely, which are downloaded as sets of files on the local disk of the server, which are then retrievable or streamable via HTTP. Go is required to install from source. The provided set of core features requires large structural changes and therefore requires a complete rewrite for best results. This rewrite is in progress in the 0.9 branch though it will take quite some time. It will be capable of transfering files from and source file-system to any destination file-system. A torrent can be viewed a folder with files, just like your local disk, and Dropbox. As long as it has a concept of files and folders, it could potentially be a cloud-torrent file-system backend. During a file tranfer, one could apply different transforms against the byte stream for various effect. -

JDA
Java wrapper for the popular chat & VOIP service
JDA strives to provide a clean and full wrapping of the Discord REST api and its Websocket-Events for Java. This library is a helpful tool that provides the functionality to create a discord bot in java. Discord is currently prohibiting the creation and usage of automated client accounts (AccountType.CLIENT). We have officially dropped support for client login as of version 4.2.0! Note that JDA is not a good tool to build a custom discord client as it loads all servers/guilds on startup, unlike a client which does this via lazy loading instead. If you need a bot, use a bot account from the Application Dashboard. Creating the JDA Object is done via the JDABuilder class. After setting the token and other options via setters, the JDA Object is then created by calling the build() method. When build() returns, JDA might not have finished starting up. However, you can use await ready() on the JDA object to ensure that the entire cache is loaded before proceeding. -
