Lowering Latency in Linux: Introducing a Preemptible Kernel
The Linux community is large and diverse, and Linux is used in embedded systems all the way through large servers. Preemptive kernel technology provides benefits beyond real-time applications. Desktop users, gamers and multimedia developers alike stand to benefit from reduced latency. A solution is needed for both the 2.4 and 2.5 kernel trees; perhaps the same solution for each is not best. With 2.5 under development, however, now is the time to implement a feature that provides an immediate gain, as well as the framework for further improvement. The result will be a better kernel.

In modern computer systems, privacy and security are mandatory. However, connections from the outside over public networks automatically imply risks. One easily available solution to avoid eavesdroppers’ attempts is SSH. But, its wide adoption during the past 21 years has made it a target for attackers, so hardening your system properly is a must.
Additionally, in highly regulated markets, you must comply with specific operational requirements, proving that you conform to standards and even that you have included new mandatory authentication methods, such as two-factor authentication. In this ebook, I discuss SSH and how to configure and manage it to guarantee that your network is safe, your data is secure and that you comply with relevant regulations.Get the Guide
