Keeping Passwords in Source Control

I learned a neat tip from my co-worker, Craig Silverstein (more on Craig joining Khan Academy), recently and I thought others might find it to be useful. It has to deal with the eternal question: How do you store sensitive configuration options (such as usernames, passwords, etc.) in source control? Typically what I’ve done is […]

JavaScript as a First Language

At Khan Academy we’ve been investigating teaching Computer Science to students in some new and interesting ways. The most interesting aspect of which is that we’re likely going to be teaching them JavaScript as their first language.
