Like two years ago, my students were asked to upload a simple website using the knowledge they acquired during my lessons, and I’d like to share them … Read more

SHITSTORM – Cos’è e come evitarlo

October 10, 2016 by Alessandro Gonella

Uno tra i fenomeni più dannosi su Facebook viene nominato Shitstorm (tempesta di escrementi). Questa tecnica consiste nel diventare amministratore di un gruppo su Facebook, eliminare i proprietari originali ed aggiungere i propri complici. Avendone il controllo completo, i nuovi amministratori eliminano il gruppo o lo tempestano con post mirati a demolire la community creatasi, costringendo i membri ad abbandonarlo.

Viviamo in un’epoca di idioti tecnologici, ma non è colpa loro

June 15, 2016 by Alessandro Gonella

Spesso mi domando, quando sfoglio Facebook, se il mondo sia sempre stato popolato da idioti o se la percentuale sia notevolmente aumentata nel giro degli ultimi anni. Basta entrare in un social network per rendersi conto che, dipendentemente dagli amici che avete, l’intelligenza o, più in generale, la capacità di pensare, sembra essere una qualità sempre più rara. Mi riferisco in particolare alla proliferazione delle bufale sui social network.

Rocksmith 2014 free alternatives

September 8, 2016February 29, 2016 by Alessandro Gonella

If you heard about Rocksmith 2014 or its previous version (just “#Rocksmith“), you know that it’s like #guitar hero with a real guitar. You buy the game and the Ubisoft Real Tone Cable for connecting a standard electric guitar to your PC, Mac or console. The game is not that expensive, nor is the cable (but many agree that it’s too expensive for its quality, that’s why I found a workaround for using a standard cable). Anyway, you may be looking for cheaper Rocksmith 2014 alternatives, or games that teach you how to play guitar better than Rocksmith 2014 do.

What is ZigBee? Key concepts

April 18, 2016February 26, 2016 by Alessandro Gonella

What is ZigBee? It simply is an interesting wireless protocol for communication between devices.

ZIGBEE KEY CONCEPTS

A legitimate question is: “Do we really need another wireless protocol?”. The answer can be found analyzing the reasons that brought to the creation of ZigBee by the ZigBee Alliance. ZigBee was born with a mission to define a complete, open, global standard for reliable, cost-effective, low-power, wirelessly networked products addressing monitoring and control. In particular, the focus was on:

Large networks (a large number of devices and a large coverage area) that could form autonomously, and operate very reliably and securely for years without operator intervention.
Very long battery life (years of use from a pair of AA cells), very low infrastructure cost (low device and setup costs), very low complexity, and small size.
A relatively low data rate.
A standardized protocol, allowing multiple-vendor, interoperable products for the global market.
