As always, we are not counting on ISO’s publication speed to call it C++20, it’s C++20 because WG21 completed technical work in February.

The AI is taking too long to reply; we need to speed it up.

This blog post gives a glimpse of the computer systems research papers presented at the USENIX Annual Technical Conference (ATC) 2019, with an emphasis on systems that use new hardware architectures. Intel Quick Assist Technology (QAT) was the focus of the QZFS paper which used this new hardware device to speed up file system compression.

Earlier this month I spent a week at the OpenStack conference. But once you realize that there are, in fact, several OpenStack conferences happening at the same time and place, it makes more sense. We also virtualize really well, for those OpenStack users who are focusing on managing armies of developers and swarms of MIS systems.

One of the big topics at the OpenStack conference was how to prepare and implement a successful transition to 5G. In fact, 5G has plenty of valid use cases, one of which is virtual reality. Unfortunately, this means that the age-old Telco bugbears will rear their ugly heads again, including latency. This requires 1 ms network latency.

I've suggested adding a command to docker to make listing at least the top-level PIDs in containers easier. ## Virtual Machines The two main technologies on Linux are Xen and KVM (and there's Bhyve for BSD). What happens if processes really do try to populate all that virtual memory?

One of the most significant announcements of the entire conference to me was that of per-function concurrency control. Correspondingly, 3GB functions should see a 2x CPU performance improvement over 1.5GB Lambdas, but this is through doubling the number of cores the function has access to, rather than double the virtualized time-slices.

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.
