- 4. 无锡控博科技2017 Linaro and 96boards 96Boards is a range of hardware specifications created by Linaro to make the latest ARM-based processors available to developers at a reasonable cost. The specifications are open and define a standard board layout for SoC-agnostic (processor independent) development platforms that can be used by software application, hardware device, kernel and other system software developers. Boards produced to the 96Boards specifications are suitable for rapid prototyping, hobbyist projects or incorporation into new systems for a wide range of applications including desktop and laptop computing, the digital home, digital signage, point of sale (POS), high-end audio, robotics and drones, artificial intelligence, virtual reality, IoT and industrial control. Standardized expansion buses for peripheral I/O have led to a wide range of compatible add-on mezzanine boards that will work across a variety of 96Boards products. Users have access to a wide range of boards with different features at various price points. In addition, some SoC vendors have announced long term availability of the SoC to encourage their use in products with long life cycles.

- 18. 无锡控博科技2017 AppArmor AppArmor is an effective and easy-to-use Linux application security system. AppArmor proactively protects the operating system and applications from external or internal threats, even zero-day attacks, by enforcing good behavior and preventing even unknown application flaws from being exploited. AppArmor security policies completely define what system resources individual applications can access, and with what privileges. A number of default policies are included with AppArmor, and using a combination of advanced static analysis and learning-based tools, AppArmor policies for even very complex applications can be deployed successfully in a matter of hours.

- 24. 无锡控博科技2017 uC3DP 3D Cloud Printing In this system, we use 20 bubblegum-96 boards, we called ‘Sheepdog Client’, to operate 20 printers (as the sheep role) and one bubblegum-96 board called ‘Shepherd Server’ to manage these 20 boards. When we submit the .stl file, ‘Shepherd Server’ will analysis the file and check if it’s possible to print well, or fixed the model bugs. Next the model file will be sliced automatically by “Shepherd Server” and pushed to “Sheepdog Client”. Finally the “Sheepdog Client” will operate the sheep, I mean the 3D printers, to print the model.
