While it’s sadly premature to say that the survey took place at the end of the COVID-19 pandemic (though we can all hope), it took place at a time when restrictions were loosening: we were starting to go out in public, have parties, and in some cases even attend in-person conferences.

At the Linux Plumber's conference there were at least 24 talks on eBPF. eBPF should stand for something meaningful, like Virtual Kernel Instruction Set (VKIS), but due to its origins it is extended Berkeley Packet Filter. In reality, eBPF is more like the v8 virtual machine that runs JavaScript, rather than JavaScript itself.

The work includes changes to the CHERI ISA, the C compiler, the C language runtime, the virtual memory APIs, and the CheriBSD kernel. On a context switch the kernel saves and restores user-thread register capability state, and updates virtual-physical mappings. The protections are hardware implemented and cannot be forged in software.

Because Google intends to change the platform to Kotlin, many programmers have chosen Kotlin for Android app development and programming. It runs on the Java Virtual Machine.

It is much more difficult to publish truly risky, revolutionary research due to implicit filters in what gets funded and what makes it past a program committee. Virtualization, for instance, was being addressed by IBM in the 1960s. At other times, the PC’s response is to push the paper to another conference.

In the first step we might reach this goal by combining the fastest mobility services through a digital platform; in the next, it might be a task fulfilled by Virtual Reality.

bpftrace uses BPF (Berkeley Packet Filter), an in-kernel execution engine that processes a virtual instruction set. BPF has been extended (aka eBPF) in recent years for providing a safe way to extend kernel functionality, and has become a hot topic in systems engineering, with at least 24 talks on BPF at the last Linux Plumber's conference.
