It's not fun until you've broken some old lady's thumb. I wonder if this is deep enough in a comment thread for the downvoters to not punish me for an entirely worthless inside-joke comment.

Your assumption was correct. And same to all of you.

True, but the great grandparent post is by an old friend -- and he's probably still right about node.js in the near future ;)

While this specific project relies on a lot of GAE's batteries-included stuff like memcache and Appstats, please feel free to fork and support new environments.

Thanks Tyler, thrilled to hear it might help. Always comforting to know it didn't explode the first early adopter's project ;)

Appstats is used to capture all the RPC timing and call stacks, but unlike ordinary setups you don't have to configure AppStats or unleash on a minority of real users to avoid perf overhead.

I met with these guys a few days before they went to their final Thiel presentation to talk a bit about where we're heading w/ Khan Academy and their brainstorms. @david and @nick, congrats on making the cut! Super nice, motivated guys. Hop

You're definitely not mistaken. Use either link -- applications welcome.

Great tips. I've always wondered what the cache hit ratios are like for various site's userbases when using Google or Yahoo's CDN for a popular library.

Not at the moment, no. We're tackling some lower-hanging fruit, but this sort of community tool is obviously on our horizon.

At the moment, yes, math only. We're working to entirely cover K-12 math before moving on. You can jump to any area or exercise you want at any time. We suggest exercises, but I've seen plenty of 5th graders jump to Calculus and play around

Can't agree with this enough. Every time we make a new chart I think to myself, "Well that wasn't rocket science," and then when we show teachers they go absolutely nuts .

It's stunning how easy it is to spot a specific lack of "automated production monitoring" after something fails. Hey idiot, you should've been testing that thing! I've seen all of Fog Creek's automated production monitoring courtesy of thei

Really helpful. Using this to improve www.khanacademy.org results right now. I find this slightly easier to parse than pagespeed/yslow and look forward to the "performance changes over time" reports.

Bingo. Dismissing Khan Academy because it's currently mostly known for videos is just as dangerous as dismissing any tiny HN startup that's focusing on a core idea and, once lessons are learned, iterating from there. We're not arrogant enou

Completely agreed (on Khan Academy team). If you check out the video from that article ( http://www.youtube.com/watch?v=hw5k98GV7po ), you'll see a lot of the strides we're making in the areas of individual assessment (mathematics only at t
