When these courses started coming out I was very excited. Now that there are so many of them, I find myself being interested in too many and being paralyzed by excessive choice, to the point that I've gone back to good old books for my self-learning.

It boils down to choosing the top 2 courses. It's difficult to do beyond that if you have a day job. One can still score high on the exams but you will have very little time left to reflect on the material.

Cofor• 14 years ago

I'm feeling the exact same way. Fortunately, the fact that you can download the videos help to be dedicated to one course at a time.

I signed up for the 'build a web browser' class. Sounds like a fun challenge to write a HTML and js parser

melipone• 14 years ago

Which class is that? udacity or coursera?

Mutinix• 14 years ago

Udacity. http://www.udacity.com/overview/Course/cs262

I almost feel as if it isn't fair. My university offers none of these things at the undergraduate level -- compilers isn't even offered at all. Although I am an advocate of this paradigm shift taking place, and am happy to be alive during a time where radical changes to education are surely to be made, these courses being offered make me really have second thoughts about putting all my time towards my university's summer courses to graduate as soon as I can. I hope they don't start charging by the time I finish undergrad.

TLDR: i jelly

MaxGabriel4• 14 years ago

Take udacity/coursera courses during the summer instead?

milesstevenson3• 14 years ago

I wish. Unfortunately I can't skip summers while trying to get a double degree, if I want to finish in any reasonable time -- or before scholarship money runs dry for that matter.

Homunculiheaded• 14 years ago

why not work within the system you're in? At my university a bunch of grad students got together wanting to do ml/pgm/nlp-class, so we put together a small group, added a semester project plus paper presentations to make it worthy of a grad class. It's a bummer that the coursera courses started so late, but otherwise it's working out great. We help each other out and teach each other new stuff, and in the end get credit ;)

If you can't get departmental approval for something like that, then you should at least be able to swing an easily justifiable independent study out of one of the free classes.

milesstevenson3• 14 years ago

That's a damn good idea. Gonna ask my advisor about it Monday.

jcurbo• 14 years ago

What kind of undergrad CS curriculum doesn't have a compilers class? I thought that was a fairly common part of most CS curriculi.

barfoomoo3• 14 years ago

Any opinion on Udacity's compiler classes versus Coursera's? There is a gap of one week between them, so we can try both and choose the one that suits us, but still, any gut feel?

i don't see a Udacity compiler class

dhawalhs2• 14 years ago

Its called "CS262 - Programming Languages - Building a Browser " by Wes Weimer http://www.udacity.com/overview/Course/cs262

dhawalhs2• 14 years ago

I feel like Udacity's compiler class would be more practical and more entry level as compared to Coursera. Its target audience are the people who finished the recently concluded CS101 course. Coursera's version would be more theoretical, thorough and closer to a Stanford level undergraduate class. Coursera's version has midterms as well exams. So I feel like it would be around 10 weeks long as compared to 7 weeks for Udacity.

Like you I plan to try both of them and ideally finish both of them. I am also waiting on them to announce a part 2 of the Data Structure and Algorithm class.

barfoomoo3• 14 years ago

Thanks for chipping in. I am leaning towards the Coursera one after reading your comment.

MaxGabriel4• 14 years ago

I'm not experienced much on implementation differences between compilers and interpreters, but Coursera seems like a compilers course versus Udacity's interpreter.

I personally much prefer Udacity's format--short videos (30 seconds to ~7 minutes) with a question after most of them, and then an explanation video. The Coursera courses I've seen have 15 minute videos/1 question, so I don't find myself retaining the material as well.

Moreover, Udacity (atleast for CS373) asks programming questions as quizzes, so you have more exposure to the programming rather than just the theory.

I don't know if this will be as bad for a compilers class, but CS373 definitely let a lot of the math be magic versus Coursera's Machine Learning class.

spacemanaki• 14 years ago

I don't think they are both compilers classes. At many universities there's an undergrad class with "programming languages" in the name (principles of ..., paradigms of ..., etc). Compilers is often a separate, more advanced class, perhaps with the PL class as a prereq. Based on the syllabi the two classes seem to follow this tradition, with the Udacity class being the PL class and Coursera the compilers one.

barfoomoo3• 14 years ago

I am in a fix after seeing Coursera's list of classes as to whether to take the automata class or the compiler one? Any opinions on this? I have not done both at university level as I am a self taught programmer.

MaxGabriel4• 14 years ago

I will also add that if you're finding scheduling conflicts to be a problem with finishing homework, Udacity is offering CS101 and CS373 without homework deadlines. http://www.udacity-forums.com/cs373/questions/34839/we-are-l...

Another thing to keep in mind is to avoid "over registering" by trying to do too many courses - some courses are rather intensive/ time consuming.

Who grades the homework assignments?

MaxGabriel4• 14 years ago

They're graded by a computer program. Usually you are writing function(s) and need to return a correct value.

As CS373 progressed it got more complex: you worked from some helper code (like a matrix class) and had multiple test cases to test your program.

joeag• 14 years ago

I think that's a great move by Udacity. I am trying to catch up on unit 6 right now in CS101. It's definitely a challenge to keep up if you are doing the course as a "hobby". Of course I also don't really care about the certs so as long as the course material is available I'm happy.

For noobs like me I highly recommend the CS101 course, I found that a lot of stuff I was struggling with in Learn Python the Hardway (a great resource as well by the way and many thanks to Zed for making it available) and other sources online became clearer to me during the CS101 course.

I am looking forward to CS253:Web Application Engineering next.

Shameless plug but here is something similar I am currently working on: http://coursebacon.com/

marlek• 14 years ago

Are there any repercussions on choosing more courses and then dropping some after a couple of weeks? I guess it will be hard following more than two with college semester coming to an end, but I like at least 4 or 5 of these online courses and I'd like to see how some of them are going for a few weeks

evoxed• 14 years ago

There are none. I've signed up for everything that looked interesting two months ago and have been active in... 6 of them (counting CS101 that just finished). The rest I'm glad to have registered for since I can still keep up with the materials and lectures without doing the assignments.

One other website that people might find interesting is MITx's program. http://mitx.mit.edu/ So far, I've tried Coursera and Udacity. Udacity: 1. Of the classes I took, only Udacity had programming exercises. For one of my friends, who had never taken programming, the course managed to capture his interest.

Udacity's courseload is:

i: video followed by a short quiz(multiple choice, fill in the blank, etc.) or a programming exercise(Create a function that takes 2 numbers and outputs the bigger one, etc.) There are generally anywhere from 25-40 videos, each 30 seconds to 4 minutes long.

ii: A series of homework assignments. These can be either quizzes or programming tasks. You can submit them, but you don't know whether you got it correct until some deadline, when your homework is graded. THe programming exercises are quite a bit harder.

One of the ones my friend struggled with for a while was a task to build a function that checked whether a sudoku square was valid when entered in a certain format. iii: At the end of each week, there is a time where they have some kind of IRC/audio channel set up, and you can ask them questions live.

2. All the courses are the same quality. Also, they seem to truly have adapted learning into a digital environment, as opposed to certain other places, like MIT's OpenCourseware

Coursera, on the other hand, seems to be a series of lectures that they then overlaid questions on too.

Some teachers' classes are quite obviously just lectures, with some quizzes added on as an afterthought, while other teachers have incorporated them quite nicely. Coursera, my guess is, will also probably have more courses on offer than Udacity soon, since it's a collaboration between several schools.

TLDR: Try them both. I personally prefer Udacity, but there's no harm in signing up for one and then dropping it.

It sounds like you haven't really looked at Coursera? It has assignments, including programming assignments.

shawnps• 14 years ago

Is there anything like Udacity/Coursera for non-CS courses? I'd love to do some Advanced Japanese.

florestan• 14 years ago

Can very much recommend the Udacity's courses. They are well planned and a big plus is that the homework spans from quite easy task, to some rather difficult.
