The kvm virtualization way
KVM provides virtualization capabilities using the Linux kernel. It supports full virtualization of x86, PowerPC, s390 and IA-64 architectures using hardware extensions like Intel-VTx and AMD-V. KVM leverages existing Linux components like the scheduler and uses the Linux security model. Guests are scheduled as regular processes. Paravirtualization is used to improve performance through virtio drivers and paravirt_ops. KVM development is ongoing with goals of supporting more hardware features, improving scalability and integrating with management tools like libvirt.

M2M, IOT, Device Managment: COAP/LWM2M to rule them all?
M2M is rapidly growing and since its early days different “standard” protocols have emerged (e.g. OMA-DM, TR-069, MQTT, …) or are emerging (e.g. CoAP or Lightweight M2M).
Understanding which protocol to use for which application can be intimidating, therefore we propose to give an overview of these protocols to help you understand their goals and characteristics.
We’ll present common M2M use cases and why they usually require more than just one protocol ; we will also see whether CoAP associated with Lightweight M2M allows to forge “one protocol to rule them all”.

Introduction to Arduino
Course: Introduction of Engineering and Design
Faculty: School of Electrical Engineering and Informatics
Version: 2016
An introduction to Arduino
In a nutshell, an Arduino is an open hardware development board that can be used by tinkerers, hobbyists, and makers to design and build devices that interact with the real world. While Arduino refers to a specific type of board design, it can also be used to refer to a company which manufactures a specific implementation of these boards, and is typically also used to describe the community around compatible boards made by other people or companies which function in a similar way.

Introduction to Arduino
1) Arduino is an open-source electronics platform used for building interactive objects that can sense and control the physical world. It contains a microcontroller and can be programmed to sense input from sensors and control outputs like motors or lights.
2) The Arduino programming environment allows users to write code and upload it to an Arduino board. It was initially developed in 2005 to make electronics projects more accessible to students.
3) Popular Arduino boards include the Arduino Uno, Leonardo, and Mega. Arduino is advantageous because it is inexpensive, has a simple programming language, and has a large community of users developing sensors, modules, and applications.
Introduction to Arduino
Richard Rixham introduces Arduino, an open source hardware and software platform that allows users to build physical computing devices ranging from flashing lights to robots. Arduino uses an inexpensive microcontroller board and IDE to make programming in C/C++ accessible. It has digital and analog pins that can interact with sensors and actuators. Common Arduino models include the Uno, Mini, and Mega. Shield add-on boards provide extra functions like wireless connectivity. Example projects and resources for learning more are provided.
How to use an Arduino
It covers several topics: basics, drivers and shields, GPIO, compilers and IDEs, hradware protocols I2C, SPI, UART. The presentation also provides several examples: DC motor control, stepper motor control, reading analog data ADC, what is DMA and a music equalizer (both software and hardware).
How to Hack Edison
The document provides an overview and introduction to using the Intel Edison board, including what Edison is, how to power it up and boot it, connecting to WiFi using ConnMan, getting started with Yocto to build a custom Linux image, and connecting hardware like GPIO. Key topics covered include using MRAA to control GPIO pins from code, booting processes involving the boot ROM and U-Boot, and recommendations to use the mini breakout board or buy from Fry's for beginners.
Athens IoT Meetup #3 - Introduction to ESP8266 (Pavlos Isaris)
The ESP8266 WiFi Module is a low-cost WiFi microchip that allows microcontrollers to connect to WiFi networks. It has an integrated TCP/IP stack, onboard processing power, and operates at 3.3V. It can connect to WiFi networks and make HTTP requests using simple AT commands. The ESP8266 comes in many modules that vary in available GPIO pins and firmware versions, which can impact the baud rate used to communicate with it from another device like an Arduino.

The Things Network - Athens
The document discusses plans to create an open and decentralized Internet of Things (IoT) network in Athens, Greece called Athens LoRaWAN. It will allow users to own and operate their own IoT infrastructure using low-cost long-range wireless technology. The network aims to be open source, treat all data equally through net neutrality, and keep users' data private through end-to-end encryption. It hopes to support various IoT applications related to environmental monitoring, agriculture, and asset tracking. Milestones include deploying initial gateways and sensors, expanding the community, and eventually connecting other cities in Greece to the network.
WeatherXM at IoT Boussias Conference 2015
1) The document discusses using an Internet of Things (IoT) network based on Long Range (LoRa) wireless technology to create a grassroots hyperlocal weather forecast system.
2) It describes setting up low-cost DIY LoRa gateways and weather sensor nodes to collect data on actual weather conditions and transmit them over the network.
3) This network could enable advanced community-level weather analytics and services by providing "big data" from localized sensor measurements, helping cities like Athens work towards becoming open smart cities.
