DragonFly provides an opportunity for the BSD base to grow in an entirely different direction from the one taken in the FreeBSD, NetBSD, and OpenBSD series. DragonFly includes many useful features that differentiate it from other operating systems in the same class. The most prominent one is HAMMER, our modern high-performance filesystem with built-in mirroring and historic access functionality. Virtual kernels provide the ability to run a full-blown kernel as a user process for the purpose of managing resources or for accelerated kernel development and debugging.

Clear Linux OS is an open source, rolling release Linux distribution optimized for performance and security, from the Cloud to the Edge, designed for customization, and manageability.

Designed so that the user is able to quickly and easily manage their custom configuration vs. system configuration. Clear Linux OS optimizes across the whole stack: the platform, kernel, math libraries, middleware layers, frameworks, and runtime. Clear Linux OS has an automated tool that is constantly scanning for CVEs, which are patched accordingly. This strict separation between User and System files allows for easier manageability and simplifying customization.

For a more detailed comparison between RTOS and Super-loop, take a look at the advantages of using an RTOS. High-Speed real-time operation with low interrupt latency. Small footprint for resource constrained systems. Unlimited number of tasks each with 254 priority levels. Unlimited number of mailboxes, semaphores, mutex, and timers. Support for multithreading and thread-safe operation.

It includes all the software you'd expect for your daily tasks — email, web browsing, word processing, gaming, and much more. With a small community of dedicated developers, MidnightBSD strives to create an easy-to-use operating system everyone can use, freely. Available for x86, AMD64 and as Virtual Machines. The FreeBSD project has developed a reliable server operating environment, but often usability and performance on the desktop is overlooked. Scheduling, allocation of resources, security settings, and available application support should be tailored to desktop users. Many of the BSD projects are tailored to servers or older hardware. Others are distributions of FreeBSD with a nice graphical user interface, but still suffer from server-centric design under the hood. We did not fork FreeBSD as a result of a falling out, but rather as an excellent starting point.

The µ-velOSity RTOS is the smallest of Green Hills Software's family of real-time operating systems. Implemented as a C library, it can be easily ported to a number of target architectures. It has a streamlined design and is tightly integrated with the MULTI IDE, making µ-velOSity both easy-to-learn and simple-to-use. µ-velOSity offers a clear, concise API that reduces development time and improves product maintainability. As a result, you can cut costs and speed time-to-market. For developers moving from standalone or no-OS configurations. With its efficient design and minimal footprint, µ-velOSity fits better in on-chip memory than competing products. Eliminating the need to access off-chip memory dramatically increases execution speed. µ-velOSity was designed to minimize the number of CPU clock cycles needed to boot, which is critical in embedded devices that require extremely fast boot times. µ-velOSity is also the ideal RTOS for embedded devices with stringent power requirements.

Developers are much more productive on Ubuntu than handcrafted embedded Linux. Sharing a platform shares the cost. Licensing is cheaper, updates more tested and maintenance shared. Familiar and widely used Ubuntu means easy CI/CD, better tools, faster updates and better kernels. Linux is not a differentiator. Use pre-enabled boards and focus on software unique to your story. Managing a familiar environment and platform is easier and cheaper than a specialist OS. Naturally. More Linux developers choose Ubuntu, so the talent pool is deeper and broader. Tap the biggest talent pool. Ubuntu is ahead of the pack by every measure. Productivity starts with reuse. Accelerate developers with the world’s largest package selection.
