Da Vini Code

Simplicity is the ultimate sophistication. – Leonardo Da Vinci.

I am Vini. I like to code. Hence the title.
I love my work. And hence the blog.
I make mistakes. Hence the rotten tomatoes. (!) Er.. Just hope I don’t get that as often.

More Haskell…


So today, I was pondering How difficult it’d be to implement the Sieve of Eratosthenes in Haskell.

Turns out, very easy after all.. and more elegant.

sieve [] = []
sieve (x:xs) = x : sieve [p | p <- xs, p `mod` x /= 0]

So With that figured out, A new challenge was to solve this for any n. O’course, my earlier much simpler solution would have sufficed –

foldl (lcm) 1 [1..20]

But that doesn’t quite use my own implementation of the Sieve of Eratosthenes algorithm, does it?

So that needed to be corrected 😉

So here’s my solution –


For the love of Haskell…


Haskell never fails to impress even the mediocre programmer in me.
Here’s something I have attempted solving using Haskell.

Problem –
Find the sum of all the even-valued terms in the Fibonacci sequence which do not exceed four million.

Look mom.. My first Haskell code


These days I am trying my hardest to learn Haskell.
Found these 2 great online resources Real World Haskell and Learn You a Haskell.

An attempt to solve a rather simple problem from codechef took me close to 2 days.
Not due to the lack of looping constructs..
Nor because I cannot think recursively.
But primarily due to the fact that Haskell doesn’t make it easy to mix pure and impure code.
It took me quite a while to understand that a little monadic constructs such as mapM, forM exists. And the let bindings for sprinkling pure code in between impure code.

First things first, Happy new year one and all.

It’d be almost sinful if a programming blog doesn’t start with a “Hello World!”.
Oh That’s but a cliche, right?
Not if you use exotic languages, I say.
How about a “Hello World!” in one of the smallest Turing complete language, Brainfuck?
