Thoughts Ltd

Thoughts Ltd is a software and trademark development company owned by Derek Sivers. All projects are listed in the top menu.

Programmer notes common to all projects:

PostgreSQL database: Projects only use PostgreSQL. Install it to develop this software. Databases are strict, with foreign keys and constraints in the schema itself.
Central database of all People: Instead of duplicating people's name, email, etc for each project - all people are kept in one central database, and all other projects just refer to the person_id.
Multi-lingual: Most sites are fully multi-lingual. See musicthoughts.com or sivers.org for two live examples. For these, nothing should be hard-coded in English. It should be a language, not the language. The techniques for language setting/switching are common throughout these sites.
Multi-currency: All sites that deal with money are multi-currency. Money is always saved as a currency code and millicents. This lets the database deal only in integers to avoid floating point errors. A shared Money class knows how to display each currency correctly or convert it into others.
Rails 3: Instead of trying to teach everyone my unique PHP framework, all projects will standardize on Rails 3.
REST Server + dumb client (on the fence about this): Because each project is a single tool, meant to be used by other sites/apps/interfaces, make each project a fully-featured REST server first, and the website is just a client, as described here. This will ensure that all outside clients can do everything our website can do, and prevent code duplication. REST server has very strict authentication and validations for every action, so client can be dumb.
Question everything: I'm an amateur. Everything here is just an idea. Please tell me when it can be improved.
