hai

Hai is a little social platform. It's an experiment in social networking.

Hai was conceived and built by Brent P. Newhall.

The architecture is basic LAMP (Linux, Apache, MySQL, and PHP). The PHP uses no libraries; it's all written from scratch.

Features include:

• A robust set of post formatting options, using a restricted set of HTML, BBCode, and Markdown.
• Anonymity. An account can consist solely of a username and password.
• Live preview of post formatting, using JavaScript.
• Drag-and-drop image and video uploads, using JavaScript.
• Each post can given a topic (called a "World"), and users can subscribe to Worlds.
• Users can create and join Rooms, which function much like IRC chatrooms. They even update live with new posts as they're posted.
• Hashtags.
• Password recovery via email or SMS, and users can specify multiple emails and phone numbers.
• Passwords are stored as encrypted DES hashes, using a 36-character salt.
• Notifications ("pings") of comments on your posts, of comments on posts you've commented on, and of posts in which you've been specifically mentioned.

If you'd like to help, here are some aspects with which I could particularly use help:

• Refactoring of large functions into more atomic functions.
• More unit tests in run_tests.php.
• Better security on the AJAX calls.

Setup

You will need to create a database using the database structure described in hai_prod.sql, and you will need to create a database configuration file named hai_db.cfg (ideally stored outside of your web root) with the following statements:

DEFINE( "DB_SERVER",   "(database hostname or IP address)" );
DEFINE( "DB_NAME",     "(database name)" );
DEFINE( "DB_USER",     "(username)" );
DEFINE( "DB_PASSWORD", "(password)" );

$crypt_salt = "(some text)";
