The longer a post has been around, the most points it requires to get to the front page.
I believe this is still relevant: http://amix.dk/blog/post/19574

I expect it's just luck. I submitted the same story and it also sank. Sometimes the gods of HN are kind to you, and sometimes they're cruel. Don't sweat it!

#5One nice thing is that the instructor is Martin Odersky (who created the language).

Are you interested in spreading knowledge, or are you interested in karma?
If the former, why do you give a shit?

#7This looks to be a really good class. I watched part of the first lecture today and it really is more about functional programming then Scala.

#8So far I'm liking the way the course material is structured. In the first week Martin is guiding you through call-by-name and call-by-value in the lamda calculus, but without its syntactic peculiarities and without really mentioning lamda calculus more than once in passing. I think this is a good idea, because lambda seems to raise defense mechanisms in students who are seeing it for the first time. Sneaky.
Edit: I found a place where the web-based quiz mechanism used by Coursera gave me some troubles. In lecture 1.4 there is an exercise to implement functions and(x,y) and or(x,y) but using neither || nor &&. While I was able to compile and run functions that produce correct truth-tables in my Eclipse environment, the web-based form appears to be fairly tempermental with what it will accept. (Equivalent functions modulo only formatting differences made the difference between "incorrect" and "correct".) I managed to proceed by asking myself whether my function was as simple as possible: no newlines, simplest possible expression, no superfluous characters such as {}

Perhaps he is interested in spreading knowledge. His post is basically identical to this one, but this one got selected. It's natural to want to understand why, rather than simply giving up. Indeed, if he comes to understand why, then knowledge has spread.

Isn't the whole point of displaying your karma score the way this site does to make you care about it?
I know it works on me. I don't write the best comments I could, I write the ones I know will be upvoted.
