Recently I internationalized a Node/Express web application that I’ve been working on and it seems to have gone fairly well (users in multiple languages are using it happily and I’m seeing a marked increase in traffic because of it!). Not much of what I’m writing up here is particular to Node, per se, just a […]

This past weekend I gave a talk at EmpireJS on the Computer Science platform that I’ve been developing at Khan Academy. The talk explores that platform and then goes into deeper technical details about how the real-time execution on the site was achieved. I recorded the talk on my laptop (so please excuse the echo […]

I’m incredibly excited to take this opportunity to announce a new project that I’ve been leading here at Khan Academy: Khan Academy Computer Science. We’re releasing a completely new platform that targets people with no programming knowledge and gives them an engaging and fun environment to learn in. Over everything else we wanted to emphasize […]

Jeff Atwood wrote up a post today on the merits of writing a technical book in this day-and-age and specifically called out my past post on programming book profits and my work-in-progress Secrets of the JavaScript Ninja. I wanted to give a brief status update on the book and how it’s going. I started the […]

Update: Since writing this blog post I’ve been using the Open Source Pastec application to do image similarity search. It’s good, and works well, although it’s not quite as good as the commercial MathEngine service provided by TinEye. I’ve also written a Pastec node module that you may find to be helpful. I’ve been working […]

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. We’re in a very unique position as we’re primarily aiming to teach students who’ve been through our previous […]

Today we’re pushing live a complete rewrite of the Khan Academy Exercise framework (live demo). A big push at Khan Academy has been to write more-and-more exercises for students to practice with. Naturally, to increase the number of exercises that we have, we needed to make it easier for team members, and casual committers, to […]

We’re taking an innovative new approach to providing students with exercises in the new Khan Academy exercise framework (which will be released for beta testing soon). In the old framework a problem would be randomly generated and provided to the user. This would result in a near-infinite number of randomly generated problems. This ends up […]
