Today I had the opportunity to present a lecture and workshop at the CERN School Of Computing. It was a great learning experience - not just for the participants, but also for me!
In the lecture “Cloud and Containers - Everything you need to know” we explored the fundamentals of cloud computing, based on which we then introduced concepts such as #cloudnative and technologies such as #kubernetes .
The slides are already available and recordings should follow shortly.
Finally a new talk by the inspirational and prolific Brendan Gregg!

This is in addition to the ones described in LWN's recent overview: https://lwn.net/SubscriberLink/922968/4a69aa7f1f2332d7/
I should take a look at Clear Linux OS.
It's one of those #Linux distros that focuses on running #container workloads (like CoreOS, Flatcar Linux etc.), but one of the unique seeking points is that the base operating system software is compiled for the latest hardware (I.e. with AVX-512 optimizations etc.)

@jgillich JuiceFS automatically splits files into small chunks, so you could probably even run VMs on top of it :D
@jgillich I'm pretty sure you *could*, but also pretty sure you would *not want* to. However I think it's a great use case for "legacy" apps that can't natively use S3/B2/whatever storage and really on a local filesystem.
Really nice talk at #fosdem by @cdown about the status and benefits of cgroupv2

I've been playing with JuiceFS the last weekend and it's pretty slick. Basically it allows you to turn a cloud object store (like S3) into a proper POSIX filesystem (that you can mount locally).
What's actually quite interesting is that there is no server "in the middle", but instead all the logic is implemented in the client (that performs the mounting).
And the even have a Kubernetes CSI driver, which makes it very smooth for using with containers.

Next week it's time: I'll be speaking at the Kubernetes Community Days Amsterdam! I'll share how #CERN extensively uses Kubernetes, OpenShift and Operators to help users (and admins, too!)

Kramer decided to use Kubernetes for his website. Jerry tries to explain what that entails. Kramer is adamant to do it all himself.

@cks @sysadmin1138 How much memory (RAM) are those Prometheus instances using?

@wilfredh Definitely one page per module. It makes Ctrl-F so much easier.
You can still add lots of explanation / examples on the page by collapsing those sections (for example like https://pkg.go.dev/encoding/json ).

Awesome video demonstrating the principle of thermo-acoustic couplers - mind-blowing that you can convert sound into heat/cold!
