primodemuson Visualizing Types: Hussling Haskell types into Hasse diagrams

Bottom is the type without values, a function with return type bottom is a function that not returns. Haskell has the term undefined, wich causes the program to abort when you try to evaluate it.

primodemuson Yosefk - My history with Forth & stack machines

"Code is more like poetry: change this line, and now the next line doesn’t rhyme, or you’ve broken the rhythm, or you’ve put angry words into a happy poem, that sort of trouble. Which is one reason to like code ownership." Amazing.

primodemuson The Psychopath - The Mask of Sanity

"Cheating skills seem to have an adaptive value in our society. The fact is: psychopaths often end up on the top of the heap, John Forbes Nash, for example." John Nash is schizophrenic, not psycopath.

primodemuson Ask HN: How did you get started in hacking/programming?

1 - At school i tried to write a symbolic differentiation/integration program in C. I failed miserably. A year later chapter 2 of SICP blown my head to a thousand pieces... Nowadays I program in F#, Haskell and C# (mostly C#) for a living, but Lisp is still my favorite language.

2 - Programming is mostly about understanding stuff, so don't be afraid to tear thing aparts since it's ok to reinvent the wheel just to see how it's done.

If I were able to live my life anew, In the next I would try to commit more errors. I would not try to be so perfect, I would relax more. I would be more foolish than I've been, In fact, I would take few things seriously. I would be less hygienic. I would run more risks, take more vacations , contemplate more sunsets, climb more mountains, swim more rivers. I would go to more places where I've never been, I would eat more ice cream and fewer beans, I would have more real problems and less imaginary ones.

I was one of those people that lived sensibly and prolifically each minute of his life; Of course I had moments of happiness. If I could go back I would try to have only good moments.

Because if you didn't know, of that is life made: only of moments; Don't lose the now.

I was one of those that never went anywhere without a thermometer, a hot-water bottle, an umbrella, and a parachute; If I could live again, I would travel lighter.

If I could live again, I would begin to walk barefoot from the beginning of spring and I would continue barefoot until autumn ends. I would take more cart rides, contemplate more dawns, and play with more children, If I had another life ahead of me.

But already you see, I am 85, and I know that I am dying.
