At Gioorgi.com we was never a SQL fan. In 2000 we thinked SQL was boring, mostly because sql algebra could be a bit boring. Then we found this book written by one of the father of SQL. Years ago Google and then Facebook popped out with new incredible ideas, for improved and super fast scalability, which eventually turned to the “NoSQL” mantra.
But NoSQL is a mature technology, or it is only a path traced by the Social company out of there? Let’s explore together…

From the iPad package, you can build a small car. We have started the project two weeks ago. We are still searching for a good set of wheels, so this is a very basic prototype:
[nggallery id=7]
The basic structure is the inner plastic of the iPad package box.
The car is able to stop if an obstacle is put on the front. On the next releases, it will be able to turn the head and decide what is the best direction (=with the far obstacle)
The car is powered with two set of four AA Batteries. One set is for the Arduino itself, and one for the three servo engines and the Ping))) Sensor.

Utilities like Telnet and remote control programs like Symantec's PC Anywhere let you execute programs on remote systems, but they can be a pain to set up and require that you install client software on the remote systems that you wish to access. PsExec is a light-weight telnet-replacement that lets you execute processes on other systems, complete with full interactivity for console applications, without having to manually install client software. PsExec's most powerful uses include launching interactive command-prompts on remote systems and remote-enabling tools like IpConfig that otherwise do not have the ability to show information about remote systems.

Abbiamo già introdotto alcune tecnologie accessorie intorno al C++ e ad Arduino. Tra le evoluzioni più interessanti di cui vogliamo parlare oggi, c’è ne sono alcune che potremo sfruttare per Arduino, ed altre che sono meri spunti di riflessione. Andiamo ad iniziare!

L’Arduino Uno, è un micro controller tutto italiano, sviluppato in open source e che sta avendo un grande successo.
Una parte del suo successo è dovuto al fatto che costa meno di trenta euro, e per essere così economico la versione base ha un chip ATmega328 con soltanto 2 KB di RAM, 1KB di EEPROM e 32KB di memoria flash per il codice. Come implementare comportamenti complessi con risorse così scarse? L’ingegneria del software ci può aiutare?… Vediamolo assieme, in una serie di articoli che avranno come obiettivo l’ingegnerizzazione spinta del sistema di sviluppo Arduino.
