Summary of book "Clean Architecture" by Robert C. Martin

Uncle Bob, the well known author of Clean Code, is coming back to us with a new book called Clean Architecture which wants to take a larger view on how to create software.

Even if Clean Code is one of the major book around OOP and code design (mainly by presenting the SOLID principles), I was not totally impressed by the book.

Clean Architecture leaves me with the same feeling, even if it's pushing the development world to do better, has some good stories and present robust principles to build software.

The book is build around 34 chapters organised in chapters.

The introduction to Reactive Programming you've been missing

(by @andrestaltz)

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

NOTE

See https://gist.github.com/cerebrate/d40c89d3fa89594e1b1538b2ce9d2720#gistcomment-3563688 below before doing anything else.

Recompile your WSL2 kernel - support for snaps, apparmor, lxc, etc.

Yes, I've done this, and yes, it works. It is, however, entirely unsupported and assembled through reasonable guesswork, so if you try this and it explodes your computer, brain, career, relationships, or anything else, you agree that you take sole responsibility for doing it, that I never claimed it was a good idea, and that you didn't get these instructions from me .

Enable `systemd` in WSL 2

This guide will enable systemd to run as normal under WSL 2. This will enable services like microk8s, docker and many more to just work during a WSL session. Note: this was tested on Windows 10 Build 2004, running Ubuntu 20.04 LTS in WSL 2.

To enable systemd under WSL we require a tool called systemd-genie
Copy the contents of install-sg.sh to a new file /tmp/install-sg.sh:
```
cd /tmp
```

My local Ubuntu 20.04 WSL2 setup.

Enable and Install WSL2

From Windows, as admin:

dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
