These are a fantastic resource (I've actually up-voted the submission), and everyone should know about them, but do we have to see them here so often?<p><a href="http://searchyc.com/submissions/Khan+academy?sort=by_date" rel="nofollow">http://searchyc.com/submissions/Khan+academy?sort=by_date</a><p><a href="http://news.ycombinator.com/item?id=1459869" rel="nofollow">http://news.ycombinator.com/item?id=1459869</a><p><a href="http://news.ycombinator.com/item?id=1415147" rel="nofollow">http://news.ycombinator.com/item?id=1415147</a><p><a href="http://news.ycombinator.com/item?id=1351584" rel="nofollow">http://news.ycombinator.com/item?id=1351584</a><p><a href="http://news.ycombinator.com/item?id=1177230" rel="nofollow">http://news.ycombinator.com/item?id=1177230</a><p><a href="http://news.ycombinator.com/item?id=995830" rel="nofollow">http://news.ycombinator.com/item?id=995830</a><p><a href="http://news.ycombinator.com/item?id=993632" rel="nofollow">http://news.ycombinator.com/item?id=993632</a><p><a href="http://news.ycombinator.com/item?id=898167" rel="nofollow">http://news.ycombinator.com/item?id=898167</a><p><a href="http://news.ycombinator.com/item?id=892222" rel="nofollow">http://news.ycombinator.com/item?id=892222</a><p><a href="http://news.ycombinator.com/item?id=733383" rel="nofollow">http://news.ycombinator.com/item?id=733383</a>
I agree that higher education is the next wave. I am doing kinda the same thing as this math teacher but with music. <a href="http://www.MusicTrainer.com" rel="nofollow">http://www.MusicTrainer.com</a> . I should be "officially" launching soon. Please let me know what you think. I read hackernews everyday and value the opinions of the community here.
I finished my undergrad 6 years ago and want to get into a PhD program in a year or two. I expect my research will pertain to DSP and involve FFT/DFT on a regular basis. To brush up on my math (PreCalc, Calculus, Linear Algebra etc), I've been watching Khan's videos nightly. I must say his videos are a great way to recollect what you've already understood once but forgotten now.<p>I wish there was a way to speed them up though. I've thought about downloading the mp4s from YouTube and playing them locally at high-speed with VLC.
They also have an open-source code repository for some web applications that they are trying to build.<p><a href="http://code.google.com/p/khanacademy/" rel="nofollow">http://code.google.com/p/khanacademy/</a><p>I daresay that they could use technical help from all the web/javascript gurus out there.
