| | | | | A short tagline from the book Learning eBPF describes eBPF as a revolutionary kernel technology that allows developers to write custom code that can be loaded into the kernel dynamically, changing the way the kernel behaves. The key word in this phrase is dynamically. eBPF allows you to write custom code that changes the way the kernel behaves without having to implement a kernel module or integrate your code directly into the kernel. | |

| | | | | Let's see if we can hide the fact that a user is logged in! The idea is that we'll be able to spawn a shell or login in as some user (we'll choose root) and not have it show up in the output of tools like who or finger.

| | | I've been using FreeBSD on and off for many years now. I really like the project's focus on quality engineering and documentation. Recently, I've begun to look for ways to increase my skill as a software engineer while also contributing to open source software once again. Happily, joining the FreeBSD community as a developer meets both of these goals. With this in mind, I decided to purchase a UNIXy compatible laptop to develop on. | ||
