After reading this old post by Don Syme, I really liked the idea of wrapping the result of any computation into an option type to signify success and failure cases and stop subsequent computations on the first failure. It’s neat but I wanted to tweak a couple of things to make it more useful: exceptional [...]

I have a few quick rules of thumb which I follow when writing code.  Nothing earth-shaking or non-obvious; just simple ways that I avoid making the worst and most obvious mistakes. If you use a number or a string more than once, make it a constant.  Maybe even if you only use it once. Do [...]

In C#, you define an empty class, struct, or interface like this: So how do you define an empty type in F#? Well, whenever you define a new class in F#, the compiler infers the class and end tokens at the beginning and end of the class’s definition, as you can see from below: So [...]

There’re a number of built-in literal types in F#, and one of the cool things you can do is to get the byte or byte array representation of a char or string using the ‘B’ suffix, the result is the same as Encoding.ASCII.GetBytes: Pretty cool, eh?
