Porting Prezi to Elm in 99 lines of code

Elm is a statically-typed functional programming language. Its compiler produces safe JavaScript which is guaranteed to be free of runtime exceptions. Moreover Elm is packed with a bunch of powerful abstractions which let us build visual and reactive Web applications in a few lines of code.

As an example, I show the implementation of a simple framework for building Prezi-like presentations. It's just 99 lines of code!

@kangax's ES6 quiz, explained

@kangax created a new interesting quiz, this time devoted to ES6 (aka ES2015). I found this quiz very interesting and quite hard (made myself 3 mistakes on first pass).

Here we go with the explanations:

Question 1:
(function(x, f = () => x) {

Descartes, Berkeley and Functional Reactive Programming

Descartes, Berkeley and Functional Reactive Programming

By @dmvaldman

Functional Reactive Programming (FRP) is generating buzz as an alternative to Object Oriented Programming (OOP) for certain use cases. However, an internet search quickly leads a curious and optimistic reader into the rabbit-hole of monads, functors, and other technical jargon. I’ve since emerged from this dark and lonely place with the realization that these words are mere implementation details, and that the core concepts are far more universal. In fact, the groundwork was laid down many centuries before the first computer, and has more to do with interpretations of reality, than structuring programs. Allow me to explain.

There’s an old thought experiment that goes like this:

Tree

# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

tmux-vim integration to transparently switch between tmux panes and vim split windows

I use tmux splits (panes). Inside one of these panes there's a Vim process, and it has its own splits (windows).

In Vim I have key bindings C-h/j/k/l set to switch windows in the given direction. (Vim default mappings for windows switching are the same, but prefixed with C-W.) I'd like to use the same keystrokes for switching tmux panes.

An extra goal that I've solved with a dirty hack is to toggle between last active panes with C-\.

Here's how it should work:
