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.

Nanos – A Unikernel
I am a bit confused, there are three sites:
* https://nanos.org/
* https://nanovms.com/
* https://ops.city/
And I am not sure what "thing" I am using. Is there some disambiguation? I know is OPS is the orchestration CLI, but I am confused at the difference between Nanos and NanoVMs. What should I call the section of my README that deals with this tech? Currently gone with Nanos/OPS but I am confused.

Kolibri OS: fits on a floppy disk, programmed using interrupts
I work with https://nanos.org && https://ops.city - we can run thousands of these on commodity hardware.

Mirage – A programming framework for building type-safe, modular systems
Unik was just a build tool that utilized other projects like Rump, Mirage, IncludeOS, etc. It's now dead since Solo pivoted a very long time ago to service mesh/api gateways.
The GoRump port they use was from us and then we realized we needed to code our own from the ground up for many reasons so we wrote https://nanos.org (runs as a go unikernel in GCP).

Building a unikernel that runs WebAssembly – part 1
A couple unikernel projects that caught my eye in the past may be of interest to you. I have no experience with them, so I can't speak to their quality though.

Running Postgres as a Unikernel
Definitely agree with the top part, however, I should note that, ops, the tool's, whole existence is to create disk images and upload them to any cloud, any hypervisor.
In particular, both https://ops.city && https://nanos.org are Go unikernels running on GCP and their deploys take just a few seconds to push out. AWS can be even faster cause we skip the s3 upload part. We also have lots of people using Azure which would be utilizing vhdx.

Applications available in unikernels?
I'm with that organization that works on https://nanos.org and https://ops.city . If you aren't a software engineer but still would like to use unikernels you're in luck - we also have a package repository at https://repo.ops.city/ (running as a go unikernel on GCP) that will allow you to run and deploy pre-made applications. If you don't see something that you'd like to us there's also a way of importing docker containers into unikernels via ops which works for most (but not all) applications.

Ask HN: Software with biggest potential for positive impact in 5 years?
I think Unikernels like NanoVMs (https://nanos.org/) will become more important. They are more efficient and more secure than than full operating systems. Right now, I think there are no good monitoring solutions available (or at least I am not aware of any). You can't just ssh to your server, so if something goes wrong, it can be hard to debug. And they are certainly not integrated into bigger monitoring solutions like Dynatrace. But once the infrastructure is available, I would expect a large percentage of Linux servers to be replaced with unikernels.

Ask HN: How are you using unikernels?
They differ very widely. It's instructive to look at unikraft which is probably the easiest to develop on (IMHO). eg: https://github.com/unikraft/app-helloworld-cpp
Our unikernel (UKL) lets you link your Linux program with the Linux kernel and produces a binary which run in a VM or on baremetal (essentially a custom vmlinuz). It's a bit laborious at the moment, one of many things to fix before release.
