SVN Version Control
SVN synchronizes files and code across multiple computers by synchronizing those files with a central server. The central server keeps copies of each version of each file it receives, which can be retrieved later if needed. Each computer maintains a copy of the whole repository. Changes and additions are made to the local repository and then committed to the central server. When other computers perform an update, they pull down these changes.
Whirlwind Terminal/Command Line tutorial
ls: list all of the files and directories in the current directory
cd directory: change directory to
When you first start Terminal the current directory is initially /Users/slork/ (most of the time).
Essential SVN Commands
On every Slorktop, the SVN directory is located at /Users/slork/slork.
svn status: display information about the current state of the local SVN repository
svn add filenames: add new files to the local repository
svn commit -m 'message': commit any changes in the local repository, including added files, to the central server, with message as the commit message
svn update: pull down any new changes or files from the central server
svn revert filename: discard changes to filename, reverting it the last version committed to the central server
Network Communication with Open Sound Control
Open Sound Control (OSC) allows different programs running on multiple computers to communicate with each other flexibly and with low latency. It can also be used to communicate between programs in different languages, such as ChucK, Processing (http://processing.org/), Python/Ruby, and C/C++.
Communication in OSC transpires with a series of messages, formed by an address, a type tag, and data conforming to the type tag. Examples of address/type tags:
/my/cool/message ff /play/kick f /play/snare f /beat i /usermsg s
f corresponds to float, i is int, s is string.
