Udacity

I was going to write this post a lot earlier, but I’ve had a lot on my plate recently; AP tests are coming up, track is coming to a close which means a slurry of meets, and I’ve been doing a Udacity course. Udacity is a site that offers free online courses in a video-lecture/machine-graded-homework format that allows thousands of people to participate in each course as it’s happening.

It was created by the professors who taught the Stanford AI online course, which pioneered the format. It was a huge success, so they decided to create a separate organization which offered a variety of these free classes. They also bring in different people to teach the different courses.

For example, the web programming course that I’m taking is talk by one of the cofounders of Reddit, Steve Huffman. The course is quite interesting. Of courses, I taught myself HTML and PHP, but there are holes in my knowledge, both basic and advanced. The course filled some of those in, but it also teaches an area I’ve never worked in before.

The course is mostly about building an app using Google App Engine. For those who don’t know, App Engine runs a Python environment. You upload code and other files which, given a request, generate a response. You can map out various directories to either query code or directly draw HTML or other documents. Within the code, you have to write one or more handler classes which extend the App Engine API. They have functions for GET and POST requests, which then build a response. Google App Engine also has other functionality, such as data storage.

Anyways, posting will get back up to speed after the AP World History test, which marks the end of a lot of my business. Next post will be more TF2, so stay tuned.
