Letter to a Young Haskell Enthusiast, by Gershom Bazerman.

Condensed from: http://comonad.com/reader/2014/letter-to-a-young-haskell-enthusiast/

The following letter is about tendencies that come with the flush of excitement of learning any new thing. It is written specifically, because if we don't talk specifics, the generalities make no sense. It is a letter full of things I want to remember.

You’ve entered the world of strongly typed functional programming, and it is great. You want to share the great things you’ve learned, and you want to slay all the false statements in the world.

Writing jQuery Plugins for Fun and (non)Profit

We all love jQuery - it's easy, efficient, and there's tons of information online. But with that mass of information comes confusion: When you want to abstract some of your code into a plugin, how do you structure it? How do you take in options, and how can you be sure you haven't broken the way jQuery works? And when you're done, where do you put it and how do distribute it to the masses?

This talk will run through some of the basics and guide you in the right direction. In particular, we'll cover:

• structuring your plugin code
• making your code testable - and testing it!
• tracking your code on github
• getting your plugin on the jQuery site
