Last year, a pair of creators crowdfunded OpenBCI — an open source software suite and interface board that made biosensing — taking readings of electricity in the human body, especially the brain — far more affordable and accessible. Now, the same people are back with the pushes this even further with new, even more affordable gear.
On a desktop computer, you think of an operating system as a big piece of complex software. For small systems (like an Arduino) you might want something a lot simpler. Object Oriented State Machine Operating System (OOSMOS) is a single-file and highly portable operating system, and it recently went open source.
OOSMOS has a unique approach because it is threadless, which makes it easy to use in memory constrained systems because there is no stack required for threads that don’t exist. The unit of execution is a C++ object (although you can use C) that contains a state machine.
A community is bound by groupware used by its members. For open source projects, the list of collaboration tools may include wikis, distributed version control systems, bug trackers, IRC, forums, and such. The decision to use a specific tool may play an important role as it will define how strongly community members will be involved in the project. Tools that have no support for collaboration or are too complex to use may seriously limit and impede help provided by the community.
Focus on community and technology will follow. That's a fundamental principle for successful open source projects, according to the Apache Software Foundation's Jim Jagleski, a self-described and self-evident "graybeard" of open source communities.
Apache is one of the great open source success stories. First released 20 years ago, Apache serves 56% of websites worldwide. Jagleski serves on the board of the Apache Software Foundation, which incorporated in 1999, and is its most senior still active contributor.
Yesterday AMD finally posted power management support for the AMDGPU DRM kernel driver when it comes to supported discrete graphics cards like Tonga and Fiji. I've been testing these PowerPlay Linux patches since yesterday to great success. In this article are results from a Radeon R9 285 and Radeon R9 Fury when testing these kernel patches along with the latest Mesa 11.1-devel Git drivers.
These AMDGPU PowerPlay patches are working out well so far in my tests. See the two aforementioned articles for more details on this AMDGPU power management code that lands more than 45000 lines of new code into this Direct Rendering Manager driver for the latest AMD graphics processors. It's just a pity that the code is too late for making it into the Linux 4.4 kernel merge window and thus won't be mainlined for a few months until the Linux 4.5 kernel. Up to now, the newer AMD graphics cards on the open-source AMD Linux driver have been limited to whatever (low) frequencies the core and memory clocks are initialized to at boot time. With PowerPlay, they can finally (and dynamically) ramp up when to their rated specifications.
Ubuntu Linux, Canonical's open source OS, already runs on PCs, servers, phones and tablets. Now, a small company named Erle Robotics wants to bring Ubuntu to drones, too.
Erle Robotics is a start-up in Spain whose goal is to develop Linux-based "brains" for robots and drones. The company already offers products that run Snappy Core Ubuntu, the transactionally updated version of Ubuntu designed for embedded devices.
CoreOS, the company behind the popular lightweight Linux distribution for data center deployments with the same name, has recently made a big bet on containers. Today, the company is launching Clair, an open-source tool for monitoring the security of containers — and it’s also integrating Clair into its paid Quay container registry service as a beta feature (with support for Quay Enterprise coming at a later date).
The council of the Swiss capital of Bern on 12 November ordered the IT department to end its dependence on proprietary software. The council halved the city’s request for a six-year licence contract, and insisted on an exit plan. A majority of councillors wants the city to replace proprietary software by open source solutions, such as Linux and LibreOffice.
