This is an update from to my earlier Self Taught Computer Science post.

I’ve started working on the SICP Exercises and so far so good. I’m finding Scheme, the variation I’m using, frustrating but thats to be expected. It’s frustrating because there appears to be no actual standard implementation of Scheme. It’s also perverse that, because it appears so simple, and there’s no standard implementation, people try and create a compliant version of Scheme. Perhaps this is testament to how hard it is to follow a standard as opposed to blazing your own trail the way a lot of popular languages do. There’s another blog post in here somewhere comparing languages that follow standards and languages that …. evolve!

I’m using the DrScheme IDE and I love it for its simplicity. Even though Scheme is frustrating I’m finding it easy to work with. I know Functional languages are based on Lambda Calculus but until I started working in Scheme I hadn’t realised how easy it is to think in functions. This can probably be attributed to the SICP exercises being heavily slanted towards computation and interesting mathematical functions like the Wallis Product or the Fibonacci Sequence. Regardless, I’m finding it easier to think mathematically in Scheme than Perl or Java.

I’ve done one exercise in Haskell so far and its been painful. This is not because Haskell is painful it’s just that almost every tutorial on Haskell I find first wants to teach me how to use the **Haskell calculator** (my derogatory term for the interpreter), as opposed to telling me how to get the thing to compile a standalone executable. That last sentence is a rant, as I’m digging into Haskell I’m finding more material. I really don’t know what it is about this language that I find so appealing. I’ve seen some really negative reviews of Haskell online but I cannot bring myself to hate it even though it’s driving me a bit mad learning it. Only time will tell if Haskell and me are meant to get on.

So far I’m finding SICP time consuming but digestible. I’m noticing a marked increase in complexity, I’m just hoping I can get through enough during my holidays to learn something.
