Linux Foundation to Host Meego Workgroup
Linux Foundation To Host MeeGo Workgroup New Open Source Software Platform Backed by Intel and Nokia will Power the Next Generation of Computing Devices SAN FRANCISCO, February 15, 2010 – The Linux Foundation, the nonprofit organization dedicated to accelerating the growth of Linux, today announced it will host the MeeGo project, the open source software platform for the next generation of computing devices. MeeGo combines Intel’s Moblin™ and Nokia’s Maemo projects into one Linux-based platform. MeeGo, announced today in a joint release by Intel and Nokia, will be deployed across many computing device types - including pocketable mobile computers, netbooks, tablets, mediaphones, connected TVs and in-vehicle infotainment systems, and brings together the leaders in computing and mobile communications as the project’s backers. MeeGo is designed for cross-device, cross-architecture computing and is built from the ground up for a new class of powerful computing devices. The workgroup will be hosted by the Linux Foundation as a fully open source project, encouraging community contributions in line with the best practices of the open source development model. The Linux Foundation expects MeeGo to be adopted widely by device manufacturers, network operators, software vendors and developers across multiple device types and for many organizations and developers to participate in the workgroup. “With MeeGo, you have the world’s leader in computing – Intel – uniting with the world’s leader in communications – Nokia – in a true open source project hosted at the Linux Foundation,” said Jim Zemlin, executive director at the Linux Foundation. “MeeGo has been built from the ground up for rich, mobile devices and will deliver choice to consumers without lock-in. -

Linux Automotive Security “Safer and More Secure”
Linux Automotive Security “Safer and more secure” Authors Fulup Ar Foll [email protected] José Bollo [email protected] Abstract Cars are expensive pieces of equipment, yet they represent a huge mass market. Adding Internet connectivity to previous elements generates perfect conditions for the growth of a viable business model on attacking “Connected Cars”. It is already well understood that cars will be connected and connected cars will be attacked. While it's still too early to predict with certainty how “Connected Cars” will be impacted by security flaws, making the assumption that a car should be at least as secure as a TV, a set-top-box or a smart phone should make sense to everyone. This white paper focuses on how Linux best practices security mechanisms that could be used today and within the next couple of years to make connected cars safer and more secure.

System Collaboration and Information Sharing Through Internet of Things
System collaboration and information sharing through Internet of Things Mälardalens Högskola School of Innovation, Design and Engineering Maja Grubisic [email protected] Tina Marsic [email protected] Thesis for the Degree of Master of Computer Science – Software Engineering 30.0 credits June, 2015. Examiner: Ivica Crnkovic Supervisors: Hongyu Pei-Breivold Mälardalens Högskola Kristian Sandström ABB AB, Corporate Research Larisa Rizvanovic ABB AB, Corporate Research Abstract The focus of this thesis is realization of system collaboration and information sharing between devices through Internet of Things. Internet of Things is a network of things, where a thing can be any device capable of acquiring an IP address. Internet of Things has been discussed in many domains. Companies are exploring the full potential of it, with the purpose of automating their services and optimizing their productivity. In this thesis we have conducted a systematic research review to investigate the existing Internet of Things solutions with respect to system collaboration and information sharing through Internet of Things. We have also implemented a prototype, using Arduino microprocessors and NUCs, to illustrate system collaboration and information sharing between the two systems.
