  Functional Programming Is Hard, That's Why It's Good

Odds are, you don’t use a functional programming language every day. You probably aren’t getting paid to write code in Scala, Haskell, Erlang, F#, or a Lisp Dialect. The vast majority of people in the industry use OO languages like Python, Ruby, Java or C#–and they’re happy with them. Sure, they might occasionally use a “functional feature” like “blocks” now and then, but they aren’t writing functional code.And yet, for years we’v...

  Difference Engine: Luddite legacy

AN APOCRYPHAL tale is told about Henry Ford II showing Walter Reuther, the veteran leader of the United Automobile Workers, around a newly automated car plant. “Walter, how are you going to get those robots to pay your union dues,” gibed the boss of Ford Motor Company. Without skipping a beat, Reuther replied, “Henry, how are you going to get them to buy your cars?”Whether the exchange was true or not is irrelevant.

  Scala feels like EJB 2, and other thoughts

At Devoxx last week I used the phrase "Scala feels like EJB 2 to me". What was on my mind?ScalaFor a number of years on this blog I've been mentioning a desire to write a post about Scala. Writing such a post is not easy, because anyone who has been paying attention to anti-Scala blog posts will know that writing one is a sure fire way of getting flamed. The Scala community is not tolerant of dissent.But ultimately, I felt that it was important for me to speak out and express my opinions. As I s...

  Currying in Python

What is Currying? Currying is like a kind of incremental binding of function arguments. Let’s define a simple function which takes 5 arguments: 1def f(a, b, c, d, e):2    print(a, b, c, d, e) In a language where currying is supported, f is a function which takes one argument (a) and returns a function which takes 4 arguments. This means that f(5) is the following function: 1def g(b, c, d, e):2    f(5, b, c, d, e) We could emulate this behavior the...

  #46 – Why software sucks

No one makes bad software on purpose. No benevolent programmer has ever sat down, planning out weeks of work, with the intention of frustrating people and making them cry. Bad software, or bad anything, happens because making things is hard, making good things doubly so. The three things that make it difficult are: Possessing the diverse skills needed not to suck.Understanding who you’re making the thing for.Orchestrating the interplay of skills, egos and constraints over the course of...
