Why is this the top link on HN? There are already numerous courses available that will allow you to learn this stuff for free from very highly ranked universities, including Stanford [1] and CMU [2], among others. This will just teach you similar things while also taking your money and giving you a "certificate".<p>I guess if you want to enter a new field and you need to have some certifiable expertise, this <i>may</i> be a good option. That being said, if the field you plan on entering really does require some documented education, having this certificate will not even put you in the same playing field as those with actual degrees in the field, not to mention those with advanced degrees.<p>[1]: <a href="https://www.coursera.org/course/ml" rel="nofollow">https://www.coursera.org/course/ml</a><p>[2]: <a href="http://www.cs.cmu.edu/~tom/10701_sp11/lectures.shtml" rel="nofollow">http://www.cs.cmu.edu/~tom/10701_sp11/lectures.shtml</a>
