Edison tools, applicazioni e molto altro

Come sapete Edison viene distribuita con un'immagine di Yocto Linux. L'immagine contiene tutto il software necessario al funzionamento di base del sistema e diverse utilissime librerie, ma per chi, come me, e' abituato ad usare GNU/Linux normalmente, troverebbe alcune mancanze fastidiose.

Yocto e' ottima per costruire distribuzioni customizzate al proprio prodotto, ma compilare pacchetti e librerie non e' esattamente banale.

IOTree, un albero di natale intelligente, con Intel Edison

Visto che vengo spesso accusato di essere poco coinvolto negli addobbi natalizi quest'anno ho deciso di partecipare attivamente all'allestimento dell'albero.

Avendo appena ricevuto un Intel Edison non potevo non sfruttarlo per rendere l'albero piu' divertente ed intelligente.

  • Resin.io releases experimental support for the Intel Edison

    Managing a fleet of IoT devices and deploying code is no easy task. Resin.io changes the workflow by leveraging Git and Docker technology!

    How It Works

    When you have new code for your end devices, all you need to do is simply perform a "git push". Resin.io builds your code into a Docker container and deploys it onto the device if/when it's online! Below is an image describing the process, found on Resin.io's website:

    The Last Line Effect

    Copy-Paste

    I have studied numbers of errors caused by using the Copy-Paste method and can assure you that programmers most often tend to make mistakes in the last fragment of a homogeneous code block. I have never seen this phenomenon described in books on programming, so I decided to write about it myself. I called it the "last line effect".

    Null Pointer Dereferencing Causes Undefined Behavior

    I have unintentionally raised a large debate recently concerning the question if it is legal in C/C++ to use the &P->m_foo expression with P being a null pointer. The programmers' community divided into two camps. The first claimed with confidence that it wasn't legal while the others were as sure saying that it was. Both parties gave various arguments and links, and it occurred to me at some point that I had to make things clear. For that purpose, I contacted Microsoft MVP experts and Visual C++ Microsoft development team communicating through a closed mailing list.

    SpaceApps NYC 2015 : A Truly Stellar Event!

    The International Space Apps Challenge is a technology development and problem solving event during which citizens from around the world collaborate to tackle challenges relevant to improving life on Earth and the exploration of space. Intel has participated in these events and has provided technical mentorship, as well as software/hardware sponsorship.

    Exploring Air Quality Monitoring Using Intel® Edison

    Air quality monitoring is an interesting topic to explore with the rises in pollution, allergy sensitivity, awareness of health & fitness, and technology innovation. The consumer marketplace has seen innovative products released bringing more awareness to air quality monitoring in the home. One such product is the smart scale. These smart scales monitor a variety of health related parameters and also the air quality. The air quality is sent to the cloud and an app can alert you to the changes in the air quality so you will know when an area needs ventilation with fresh air.

    Using Edison: Securely connect IoT Sensor to the Internet with MQTT

    Introduction

    In previous blog posts [1], [2], we’ve built the Mosquitto MQTT broker on Edison and created a sensor node for sensing motion, temperature, and light level. In this article, we will connect those sensors and actuators to the Mosquitto MQTT server we’ve built to turn those sensors into true IoT sensors.

    Using Intel Edison: Building an IoT Sensor Node

    In a previous blog post, we’ve built the Mosquitto MQTT broker that we will use as the data interface for our sensor node.

    In this posting, we will build the physical sensor node first, test it without the internet connectivity to ensure that the sensor node is working. Then we will add in the internet connectivity to make our sensor node a true IoT device.

    The Sensor Node

    The sensor node comprises of several sensors:
