Responding to a critical need for skilled technology and knowledge workers, the State of West Virginia recently established its first ever coding, app, and game design curriculum for its schools. Starting in the upcoming school year, students will be able to learn the skills required to design, implement, and release their own games, and open source will be pivotal to their development and future. read more

On Monday an anonymous group ... claiming to have breached computer systems used by the Equation Group, a team of highly sophisticated cyberspies that the security firm Kaspersky found last year was hacking targets around the world and has been tied to the NSA based in part on evidence from the leaks of Edward Snowden.

Working openly means designing for participation. "Designing for participation" is a way of providing people with insight into your project, which you've built from the start to incorporate and act on that insight. Documenting how you intend to make decisions, which communication channels you’ll use, and how people can get in touch with you are the first steps in designing for participation. read more

In an ELC talk in May, Vijay Kesavan of Intel’s Communication and Devices Group outlined plans to support new platforms and IoT ecosystems in IoTivity v2.0. In May, we reported on an Embedded Linux Conference talk by Open Connectivity Foundation (OCF) Executive Director Mike Richmond on the potential for interoperability between the OCF’s IoTivity IoT […]

Google is prepping an open source “Fuchsia” OS that can target IoT, handhelds, and laptops. It uses a new “Magenta” kernel, based on the “LK” project. Google has posted GitHub code for an emerging operating system called Fuchsia, designed for a wide range of devices. Like Google’s Android, Chrome OS, and IoT-focused Brillo, Fuchsia is […]

Serverless computing is the latest trend in cloud computing brought about by the enterprise shift to containers and microservices. Serverless computing platforms promise new capabilities that make writing scalable microservices easier and more cost effective, say IBM software engineer Diana Arroyo and research staff member Alek Slominski.

webOS, BeOS and Android heritage. The source code of Google's latest operating system has emerged, and it looks like all new code from the ground up.

This is the third and last tutorial in our series about creating CICD pipelines with Docker containers. Part one focused on how to use Docker Hub to automatically build your application images, and part two used the online Travis-ci platform to automate the process of running those units tests.

This article is about compilation and installation of PSAD (Port Scan Attack Detector) for IPFire (Linux based firewall). However, a development environment for the IPFire will be setup for the compilation of new plugin (PSAD in this case).

Testing applications is a critical part of software development as illustrated by the rise of continuous integration and automated testing. In his upcoming LinuxCon + ContainerCon talk -- Testing Applications with Traffic Control in Containers -- Alban Crequy will focus on one area of testing that is difficult to automate: poor network connectivity. He will describe a testing approach which emulates network connectivity and which integrates existing Linux kernel features into higher level tools such as Kubernetes and Weave Scope.

My first Web-related job was in 1995, developing Web applications for a number of properties at Time Warner. When I first started there, we had a handful of programmers and managers handling all of the tasks. But over time, as happens in all growing companies and organizations, we started to specialize.

Fragmentation is a longstanding Achilles heel for the Linux desktop. In a world of myriad incompatible distributions, popular apps are typically limited to one or two of the most popular distributions, and the creation of new apps is stifled. The impact of fragmentation on application developers offers a good example of the problem: To release an app for Linux, a developer must contend with different package formats and a baffling number of distributions, all of which have their own particular conventions. read more

In May, we reported on an Embedded Linux Conference talk by Open Connectivity Foundation (OCF) Executive Director Mike Richmond on the potential for interoperability between the OCF’s IoTivity IoT framework and the AllSeen Alliance’s AllJoyn spec.

runC, a lightweight universal container runtime, is a command-line tool for spawning and running containers according to the Open Container Initiative (OCI) specification. That's the short version. The long version: The governance umbrella created by Docker, Google, IBM, Microsoft, Red Hat, and many other partners to create a common and standardized runtime specification has a readable spec document for the runtime elements of a container, and a usable implementation based on code contributed to the OCI by Docker. read more
