I think constants are evil (just joking but….I will explain why). I am tired of seeing a lot of Java classes filled with the same constants repeated over and over again, instead of collecting them in a common file, which in C Language was called include files (ooooah!). Sometimes it is impossible to understand if …
In the 1980 comments were used to reduce the “gap” between unstructured code and “rationale” behind the code. C/64 Peek and poke where oscure. Gosub on function pointed by numbers was bad 8-bit systems was tight on command names and so on (think to write a python interpreter in Arduino/bbc:Micro, or look at the memory …
Today I took a light rail with my son, to bring him to school. That tram is 90 years old. It has been maintained for 90 years. Milan city sold some of them to San Francisco too.
Ciao a tutti, è venerdì! Se avete due minuti di tempo, volevo indicarvi un articolo su un algoritmo non banale, molto ben descritto qui: http://research.swtch.com/sparse This is the story of a clever trick that’s been around for at least 35 years, in which array values can be left uninitialized and then read during normal operations, …

Arduino Esplora is here! The Arduino Esplora is a microcontroller board derived from the Arduino Leonardo. The Esplora differs from all preceding boards in that it provides a number of built-in, ready-to-use setof onboard sensors for interaction. News said the price will be around 45 euros http://www.tgdaily.com/hardware-features/67998-arduino-esplora-is-ready-out-of-the-box-sans-soldering http://www.wired.com/beyond_the_beyond/2012/12/the-arduino-esplora/ Take a look at the board here …
!UPDATED! Okey I love emacs, you are allowed to say I am a nerd. But I use emacs. So I could solve your problems with a Ctrl-Alt-x kung fu combination, involving yoga-like finger movements. So do not mess with me… :D (I am like the Zohan, only with glasses :)
Are you ready for the news? Code Zauker v0.0.3 is OUT! The new version spots Case insensive indexing and searching, at a blazing fast speed. UTF-8 compliant indexing.

When Steve Jobs given some suggestions to Google, I fear he was still upset for the Android-carbon-copy of the iPhone. Because Jobs suggested Google to focus on a small subset of product (no more then five) and Google did it. And google started killing a lot of lab projects. Google Code Search was one of this …
Preludio L’ultima volta che ho provato Ruby è stato nell’aprile del 2005. Avevo sviluppato un paio di progetti di test in RubyOnRails, che allora era già produttivo. Ruby era affascinante, ma la libreria base mi sembrava ancora in stato embrionale e lo abbandonai. RubyOnRails non mi è mai sembrato avesse un vantaggio competitivo rispetto a …
Ho posseduto sia un Vic20 ed un C/64, come molti della mia generazione, credo. Il Commore 64 è stato un micro computer commercializzato tra il 1982 e il 1994, dalla Commodore Business Machine (CBM). Il vero salto di qualità con il C/64 me lo fece fare un rivista scovata in un Autogril, chiamata Commodore Computer Club, che …
This week, the nodejs community had a big flame. All was started by this blog post, which tried to slap down node.js server because of its mono-thread nature. And node.js fight back knocking down the attacker. Let’see how.
Ciao bimbo mio, oggi non parliamo di te. Parliamo di Steve Jobs, che si è spento ieri, all’età di 56 anni. Steve è il creatore di tutte quelle cose con il logo di una mela che vedi in casa, e no, la Apple non è una catena di fruttivendoli internazionali. La prima volta che incontrai …
