Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Goodbye Etcd, Hello PostgreSQL: Running Kubernetes with an SQL Database
Looking at [1], is there any reason why this couldn’t run in something like DynamoDB? I feel like the operations required would fit

What is going on with Kubernetes Microdistros?
I don't like some of the decisions that k3s makes which is why I stay away from it, but it's a great project. I'm not using kine yet, but I fantasize about using it exclusively every time I deal with etcd-induced slowness/random CPU spikes on my group of controller nodes. k0s supports kine too of course but I just haven't switched it on yet.

Databases = Frameworks for Distributed Systems
Well in some situations you can also get away with CRDTs or Gossip (SWIM), but yeah in the general sense Paxos (Raft is a Paxos-family algo). There are lots of paxos family algos to choose from[0].
> I’m also currently building a distributed search engine using etcd for the service registry, broker peer announcements, and worker queue and it’s been a good experience so far.
As a random stranger on the internet, please build an abstraction layer around etcd. Even if there's only one implementation, I've found that so many distributed projects that just never reach the scale that etcd is built for would benefit from the option of writing their own drivers (you don't need a full plugin system just a regular abstraction layer).
One example is Kine[0] for k8s -- if k8s had a built in option for writing/reading from something like Postgres from the beginning it would have been a better project for it, IMO.
If you do build a plugin system though, you can pass off the work of maintaining the other implementations!

K8s on Pg
I could spent >0s looking into this, but I've been curious how kline implements Etcd's Watch API. For the matter, I don't have much idea in general how kline handles data. Kline would be a great candidate for a blog post or introductory technical article on.
I do quickly see one issue- evidently watches presently use polling. The issue requests use of postgres triggers: https://github.com/k3s-io/kine/issues/20

rqlite 6.0: the evolution of a distributed database design
Not to be mistaken for high-availability Dqlite[1], which is one of the options one can run the k3s kubernetes distribution on (instead of etcd), via the Kine etcd shim[2]. Ultimately though the K3s team replaced Dqlite with an embedded etcd to get high-availability[3].

μMon: Stupid simple monitoring
You can easily put together something that will send UDP packets with stats at regular intervals. I’ve done that a number of times - https://github.com/rcarmo/raspi-cluster/blob/master/tools/se...

Building a bare-metal Kubernetes cluster on Raspberry Pi
I like the trays. Back when I rebuilt mine from Pi 1Bs to 2Bs* I printed a vertical holder where the Pi itself was the slottable unit, but if I were to rebuild mine today I'd print some trays and use an existing box.
One thing that I did that might make sense for that setup was that my master has a Wi-Fi dongle and performs NAT/DHCP for the other Pis - this makes it easier to do a lot of stuff, including auto-configuration.
