@IvoFlipse I love CNX! My thesis advisor was was of the people who started it in Rice University. He writes DSP articles for it all the time. At least he used to.
@Mohammad It was started by a bunch of guys at Rice. It renders LaTeX scripts into readable web pages. So you can download a LaTeX-rendered PDF of every page.
@IvoFlipse Sydney Burrus, a very influential researcher in filter design was one of the people who started it, so it's got a lot of DSP on it.
@Mohammad You can basically register an account there and publish whatever you like.
Right now our team is basically students from our high school + a high school in Singapore. We also did some online recruiting so there's other members from all over.
@Phonon I took a look at some of the whiteboard apps ... very promising.. I think we'll be able to do some DSP teaching soon - we have to experiment with each other first though.
@jellyksong Digital Signal Processing. A very powerful technique for digitized signals - but can also be used for other types of discrete data as well.
@jellyksong Well the thought is, you will be able to get tutor-on-demand via your ipad or other tablet, etc. We will find some way to communicate with you, (facetime/google hangout / skype), with a whiteboard app running in the background, so we will be able to see each others' drawings in real time, as we explain stuff
@IvoFlipse ours was a spiral down in a circle and we had an equation of how it was accelerating and we had to find how much of its weight was on the track and how hard it was trying to fly off the track and make an equation. It was terrible.
@IvoFlipse they did change it up, there is often the discussion of how fast so that it does not fall off from gravity.
@jellyksong friction and air resistance are a pain to actually solve for. Air friction is a function of V^2 so you get a differential equation that you have to solve numerically for normally. The aerospace guys at my university used to always talk about how hard it was ;)
@Kortuk True and while the ability of students to guesstimate orders of magnitude sucks, I bet if you'd hook it up with a physics engine like in the Source engine, they'd see quickly enough whether their estimate was correct :P
But honestly, calculating angular velocity gets a lot more interesting when you get to swing a wii controller
rather than having to calculate some imaginary pendulum
@GauravJain Rightly so :P
@GauravJain Btw you have a desktop which pwns all the alternatives
@Mohammad Yeah, I use Greenshot, which puts it in a folder and auto-saves it, since I use it so often, I never have to browse folders and its always the newest image
