Windows 10 (20H1 / 2004 / Mai 2020 Update) with WSL2 is out, this guide should be obsolete now.

Upgrading an existing WSL1 setup to WSL2

Docker in WSL1

Note, this is only needed on Windows 10 Home and WSL1. If you have Windows 10 Pro, you can run Docker for Windows (https://docs.docker.com/docker-for-windows).

After completing this guide, you will have a Windows 10 Home running the docker deamon via Docker Toolbox / VirtualBox. The WSL guest OS will connect to this docker deamon, and will have the Windows OS filesystem mapped as C:\ -> /c/ instead of C:\ -> /mnt/c/, which will fix path translation between docker deamon on Windows and docker client in WSL guest OS.

Merkle-less, Homomorphic Hash-based Infinite-time Stateless Digital Signatures

We will use the following terms:

pk   is public key
sk   is private key (secret key)
H    is hash function
sig  is message signature
m is plain-text message

CvRDTs are (almost?) as general as they can be

What are you talking about, and why should I care?

Now that we live in the Big Data, Web 3.14159 era, lots of people want to build databases that are too big to fit on a single machine. But there's a problem in the form of the CAP theorem, which states that if your network ever partitions (a machine goes down, or part of the network loses its connection to the rest) then you can keep consistency (all machines return the same answer to
