Sometimes people ask me what programming languages are worth to learn.
This is my list, with pointers to free implementations or important sites about the language.
The list order is just alphabetical.
This does not mean other languages are not worth to be learned, just I think in this subset there is the essence of many things you can find in other programming languages. There is something all the languages listed, but C, have in common: all this languages can be extended in theirself, that's they are programmable programming languages.

My relation with email
(Un)fortunately I receive a number of emails every day, just counting the only ones requiring a reply, so please don't think I'm rude if sometimes I don't reply to your emails about my opensource projects: I've to put at the top of my priority list emails related to work, and my time is finite. Feel free to resend the email multiple times if you really need an answer.The origin of my nick antirez
I've a great friend, Trent, and I discovered for the first time internet around 1997 with him. The first time we joined on IRC (with a modem that I purchased for an error, in exchange for a non working video card in a no-money-back computer store), his nick was Reznor, so I decided to call myself AntiReznor. It was too long for IRC, so I trimmed it to antirez. Now, even if this nick is more appropriate for a washing machines company, I continue to use it. At this point is just my name on internet ;)
Where I live
I live 50% in Catania near to the Etna volcano, 50% in Campobello di Licata (Agrigento).I lived three years in Ragusa Ibla, a beautyful place in Sicily. This is a picture of Ibla. I take a Ibla Blog (in Italian language).
Ibla is a cool place and people here in Ragusa are very nice. My origins are in the province of Agrigento, in a little town called Campobello di Licata. I was born near to the temples of Agrigento, here is a photo of the temples.
