this guy has shoulders like the navi people from avatar

[rudrivas]

Can you upload a version with better resolution, there are parts that are annoyed to watch.

Thanks

Isn't that fun length(lst) should be defined as

fun length(lst) = foldl(fn (x,a) => 1+x) 0 lst

or is it something like thanks cap for all of you guys watching the video?

[basmithtx]

Hah, I was just thinking about using finished mappers to do some pre-reduction while idling; then he mentions the combiners. :)

[DartGreene]

Cool stuffs.

[VondaFononono]

That was a great part 2 lecture.

Who needs to go to university and pay money when there are companies like Google who have he capacity to do it for free online.

I wish the video quality was better, I can't make out a thing that he's writing on the whiteboard. Otherwise this is a very interesting material.

I wish he would have used black markers instead of red. I couldn't read anything.

Either he's too smart, or he spent too much time preparing his lectures.

The lecturer's information flux density is overflowing my brain's buffers.

He needs to dwell and linger on his points longer, and he needs to repeat them. This will give ample time for people to catch up with his ideas, assuming they are important enough that one should understand them.

Basically what I'm saying is, his presentation is not casual enough. It's frustrating jibberish until I have replayed the video several times.

@mrcoder

I think that's the point of it being in a video format...

What they're trying to do: exploit the grammatical characteristics of functional programming to allow concise expression of problems of inherent parallelism, while hiding the technicalities associated with the process of reducing them into parallel components.

Input -> Process -> Output as we used to say in the olden days.

Ironically, I'm having quite a bit of trouble watching this lecture series about reliable, highly available services. It's just not loading at all for me right now, but the rest of my internet access is fine.

I had the same problem - I paused it and left it that way until it was fully buffered, then played it and it plays well.
