Life, Programming, Everything

I live in South San Jose; recently we have discovered that now that we have fast Internet, WII and Netflix, we already have access to hundre...

Actually, not monads, just functorial stuff. But programmers seems to be unaware of the fact that a monad is a special kind of functor, so.....

While at Google, I believed in two things: peer code review and unacceptability of ascii art in the code. Peer code review means you are sup...

Many many years ago people were writing their code mostly in FORTRAN, but also in PL/I. They were told by their teachers not to use too many...

If you are a Haskell programmer, this is all trivial for you; but if you are a Java programmer, you would ask yourself two questions: is it ...

Here I just want to get together a pretty much widely-known information; somehow it escapes you if you just read Java books or google the in...

I've been trying to figure out how come the only relationship between types we use to encounter is "sub". Type a is a subtype ...

Comonads still look a little bit enigmatic to programmers; I'm going to show a practical example from which one can start perceiving the...

I sincerely plan to explain in simple terms what's all this fuss about monoids, why we suddenly need these primitive structures, and how...

I'll try to explain to practicing programmers what this variance means, and how it is related to the famous and frequently misunderstood...

I think I have some ideas regarding what is the problem with inheritance and, specifically, multiple inheritance. Let's start with geome...

Recently I encountered a problem of calculating a factorset, given a set and a binary relationship. If you ask wtf is binary relationship, i...

You probably know that if you use a value in an inner class, the evil Java compiler wants you to write "final"; people do all kind...

Just posted a new part, "Category of Java Sets" , in Easy Categories For Programmers .

An Excuse Well, I decided to gather all the code related to Function class in one "universe" container class, Functions. The other...
