Riding a lambda.

Lambda is a vicious horse. It is very hard to keep riding. Time after time I’ve been suddenly bucked off by knottiness of its constructions and complexity. I feel like not moving forward at all…

After I went through several sections of pure, systematic theory in great “Learn You a Haskell”, I switched to something more “applied” – “Introduction to Haskell”. I hope these two resources together will make my Haskell journey more progressive, and comfy too.

Playing with ghci is a great fun, however in the long term it won’t give me a real programming experience. It is like playing with a complex system, or interacting with a awesome machinery if you will. I need to smell some source code though. Did you stick just with IDLE for a long time when learning Python?

Happy “functioning”!

To be functional.

The previous post was about a free book on Scala language. Book that introduces Scala and its ecosystem to an impatient person. I have made few attempts to make myself familiar with that language, but…

Java language is something I intentionally left behind some time ago. I am no longer a Java developer and won’t be. I accept JVM presence and do like some new things that runs on it, like Groovy for example, but programming in Java is boring, tiresome and mundane. Of course this is my private opinion. Great I am not a Java programmer for a living :)

What kills my passion to learn Scala is… yeah, the Java heritage. The reason I planned to get to know that language is simple – it is a functional language and its ecosystem is constantly growing. Nothing more. So…

Since my primary goal is to grasp that “functional” thing, I believe Haskell could be a better choice. Haskell is purely-functional (sounds like a flame wars, doesn’t it?), and yes, there is no Java behind the scenes.

“Learn You a Haskell for Great Good! (LYAH)” looks like a great resource to start with. The sun saying “Holy shit!” is killing me :D

Scala for the Impatient

If you are interested in Scala, and you’re impatient (who is not these days…) this could be something you’ve been looking for: http://typesafe.com/resources/book/scala-for-the-impatient

I haven’t had a chance yet to go through it anything more than briefly, but the book looks very promising. “Scala for the Impatient” concentrates on Scala itself and how to get up to speed, not on general programming matters, which is good.

I wrote this book for impatient readers who want to start
programming with Scala right away. I assume you know Java, C#, or C++, and I won’t bore you with explaining variables, loops, or classes.
