IEEE 802.1aq is a standard defined by the Institute of Electrical and Electronics Engineers (IEEE) that specifies a protocol for Shortest Path Bridging (SPB) in Ethernet networks. It was developed to address the limitations of traditional spanning tree protocols, which are often used in Ethernet networks to prevent loops. The key features of IEEE 802.
CBRP can refer to different things depending on the context. One common meaning is "Community-Based Rehabilitation Program," which focuses on promoting the inclusion of people with disabilities within their communities and improving their quality of life through various support mechanisms. Another possibility is "Capacity Building and Resilience Program," which may refer to initiatives aimed at enhancing the capabilities of individuals or organizations to better adapt to changes and challenges.
Commotion Wireless is a project that focuses on creating open-source, decentralized wireless communication networks. It aims to empower communities by enabling them to establish their own networks using inexpensive and readily available hardware. By doing so, Commotion Wireless allows users to share internet connectivity and communicate without reliance on traditional Internet Service Providers (ISPs) or centralized infrastructure. The project leverages mesh networking technology, which allows devices to connect directly with one another, extending the range and reliability of the network.
Direct reduction (DR) is a method of producing iron from iron ore without using a blast furnace, which is the traditional method for iron production. Instead of relying on high-temperature smelting processes, direct reduction occurs at lower temperatures and typically employs hydrogen or carbon monoxide as reducing agents to extract iron from iron ore.
Thread is a low-power, wireless networking protocol designed specifically for connecting smart devices in a home or building environment. It is aimed at enabling secure, reliable communication between various Internet of Things (IoT) devices, such as lights, sensors, locks, and more. Here are some key features and aspects of Thread: 1. **Mesh Networking**: Thread operates on a mesh network topology, which means that devices can communicate with one another directly and extend their range by relaying messages.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
