    JDA

    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.

    Fix Skype

    Fix Skype fixes future timestamps in the Skype messages database.

    Fix Skype is a python script and Win32 binary that is used to fix "future" timestamps in the Skype message database, such as those caused by the end of DST or by dual-booting a Linux system with time set to UTC from anywhere west of GMT. Essentially, you feed it your username and the number of hours by which some timestamps are in the future, and it subtracts that amount of time from any timestamp greater than "now".
