[$] The many faces of “latency nice”

A task’s “nice” value describes its priority within the completely fair
scheduler; its semantics have roots in ancient Unix tradition. Last
August, a “latency
nice” parameter was proposed to provide similar control over a task’s
response-time r…

Kernel prepatch 5.7-rc6

Linus has released the 5.7-rc6 kernel
prepatch, which contains a bit more churn than he would like.
“That said, there’s nothing particularly scary in here, and it’s not

l…

Managed OpenStack cheaper than self-managed?

Outsourcing OpenStack operations can significantly accelerate the OpenStack deployment process. Although most organisations are successful with the initial roll-out of the cloud, many struggle to operate it effectively post-deployment. Under certain circumstances, a fully managed OpenStack can also be a cheaper option than the self-managed one. We have recently published a webinar in which we […]

GNU Shepherd user services

One of the things which sets Guix apart from other GNU/Linux
distributions is that it uses GNU
Shepherd instead of the now
ubiquitous systemd. A side effect of this is that user systemd units do
not work on Guix System. Love, hate or extremely ambivalent toward
systemd, this means that users cannot rely on already written systemd
unit files for their regular user-level services. There are a couple of benefits to using GNU Shepherd, and not all of
them are due to it already being installed on Guix. Becoming comfortable
with using Shepherd and understanding how to write and edit Shepherd
service…

[$] Utilization inversion and proxy execution

Over the years, the kernel’s CPU scheduler has become increasingly aware of
how much load every task is putting on the system; this information is used
to make smarter task placement decisions. Sometimes, though, this logic
can go wrong, leadin…

[$] Testing scheduler thermal properties for avionics

Linux is not heavily used in safety-critical systems — yet. There is an

Five years of Rust

It seems that the Rust programming language has
only been around for five years. “With all that’s going on in
the world you’d be forgiven for forgetting that as of today, it has been

[$] The weighted TEO cpuidle governor

Life gets complicated for the kernel when there is nothing for the system
to do. The obvious response is to put the CPU into an idle state to
save power, but which one? CPUs offer a wide range of sleep states with
different power-usage and lat…
