Khan Academy Engineering

We're the engineers behind Khan Academy. We're building a free, world-class education for anyone, anywhere.

There are a number of ways to access things like databases and logging handlers in #Golang code.

Our approach eliminated whole classes of bugs and helped us achieve our goals. See our approach and some alternatives:

Analytics help us make better decisions for the learners and teachers who rely on us for a free, world-class education.

In this post, we lay out an approach to producing analytics without compromising privacy.

Some folks were quite skeptical when we announced we were undertaking a major rewrite in 2019.

Khan Academy completed the majority of the work this year and we're reflecting on what made our project successful.

First, our VP of Engineering and CTO, Marta Kosarchyn writes about the high-level levers that allowed us to beat the odds and complete a rewrite project of this size and scope.

@bnkrft We've got a bunch of openings for engineers to help fulfill our non-profit mission of a free, world-class education for anyone, anywhere while also working with cool tech like genqlient, Go, React, React Native, etc.

Go behind the scenes with @bnkrft on genqlient, a new open source #graphql client library/code generator for #golang.

Y'know how "naming things" is one of the hard things in computer science? You'll see how true that is here.

genqlient is a new #opensource, easy-to-use, type-safe #GraphQL client library for #golang.
Tested with over 300 queries at Khan Academy, some running millions of times daily: https://t.co/8j6OydxBXj

Our team has written more than 500,000 lines of Go! Faster, cleaner, more verbose? Here's what we think so far.

Do you think the #flowtype info in your #javascript is keeping you safe? Not necessarily! We use a linter to give us confidence in our #ReactNative app.

In the course of a week in March, Khan Academy's traffic jumped by 2.5x… Despite that, the site stayed up and stayed responsive, right when folks really need us.

Our VP of Engineering, Marta Kosarchyn, has blogged about how we did it:
