It's from "Monads and Gonads", a talk delivered at YUIConf 2012. Here it is: http://www.youtube.com/watch?feature=player_embedded&v=d...

Several earliest known uses of other mathematical notations can be found at: http://jeff560.tripod.com/mathsym.html

This is in fact the consequence of a fact first proven by Euler: every even perfect number is of the form (2^(p-1)) * (2^p - 1) where 2^p - 1 is a prime. That is, it's p ones shifted left by p-1 zeroes.

I can report that the Parse course is now correctly working. Thank you!

I'll check tomorrow if I'm still having issues with Twilio. I also got my provision rejected from Sendgrid, but I'm trying to solve this on my own. EDIT: Solved!

Thank you again for these wonderful courses!

I'm a fairly fanatical Codecademy user, so this is not news to me: I've been testing these courses since at least two weeks :)

Unfortunately this means I'm having all sorts of data integrity issues: for example, I can't access the third lesson in the Parse track, which is showing 9/4 exercises done. I'm also having trouble finishing several exercises in these courses, due to puzzling errors and, possibly, flawed tests.

But, wrinkles aside, I think these lectures are a brilliant way to generate leads: I subscribed to pretty much every service that has course on its API (Parse, Twilio, NPR...).

This is a very serious blunder on my part! That's an important resolution to support.

MS_BTW_UPD (which stands for "Milliseconds between updates") was changed to 18. Thank you for your feedback!

I agree: it's barely usable as it is. I hacked it this very night, and those were the best controls I was able to build. Thank you for playing and for the critique!

Another enjoyable book on this topic is "The Mathematical Coloring Book" by Alexander Soifer: http://www.amazon.com/Mathematical-Coloring-Book-Mathematics...

NestaCMS got my vote, because it's what I use for my blog. Is it really a static site generator, though? It can be used as one, I guess, but I think of it as a dyamic Sinatra app.

And Amazon IT: http://www.amazon.it/Vim-Vi-Tips-Essential-ebook/dp/B004JF4N...

Unfortunately not available to italian customers, who'd have to purchase it at 19 euros (23 dollars). Is there a legal workaround?

I am interested. I am a beginner in several languages (Ruby, Python, JavaScript, C) but I've never written serious software in any of these.

I really loved this! I liked the fact that I could read other people solutions.

Is there an equivalent for Python, or any other language?

>Aside from the article itself, I am confused by the title. Are they meaning to call themselves a "design legend"?

I think they are calling Mike Kus a design legend, who taught them these six lessons.

Please submit this! I'd love to read qualified commentary on many claims this blog post makes.
