Instructions to hack up WSL2 on Windows 10 Build 18917 to run k3s (Kubernetes) and rio

Install WSL2

https://docs.microsoft.com/en-us/windows/wsl/wsl2-install

I already had Ubuntu-18.04 installed in wsl 1. So I just did wsl --set-version Ubuntu-18.04 2

Compile Kernel

Using Ubuntu 18.04 (I'm sure any distro will work), inside WSL2 download https://thirdpartysource.microsoft.com/download/Windows%20Subsystem%20for%20Linux%20v2/May%202019/WSLv2-Linux-Kernel-master.zip and extract to a folder. The latest version of the kernel source is available at (https://github.com/microsoft/WSL2-Linux-Kernel)

Generate ssl certificates with Subject Alt Names on OSX

Open ssl.conf in a text editor.

Edit the domain(s) listed under the [alt_names] section so that they match the local domain name you want to use for your project, e.g.

DNS.1   = my-project.dev

Additional FQDNs can be added if required:

Windows 10 Development Environment for Scala

This is a guide for Scala and Java development on Windows, using Windows Subsystem for Linux, although a bunch of it is applicable to a VirtualBox / Vagrant / Docker subsystem environment. This is not complete, but is intended to be as step by step as possible.

Harden Windows 10

Read the entire Decent Security guide, and follow the instructions, especially:

Set UAC to full
Enable Drive Encryption

With the release of Vivaldi 2.2, this page is now obsolete and unmaintained. Widevine is fetched automatically on post install of our official packages. The information below and the script are left for historical reasons but will not be updated.

If you are using something newer than Vivaldi 2.2, you should not be using this script as there is simply no need. Any need you think you have for it would be a bug IMHO and thus should be logged in a bug report. Before you do so however, you should also checkout the Vivaldi help page on Widevine, on Linux

Summary

A bunch of people asked how they could use this script with pure Chromium on Ubuntu. The following is a quick guide. Though I still suggest you at least try Vivaldi. Who knows, you might like it. Worried about proprietary componants? Remember that libwidevinecdm.so is a b

alembic is great but lacks an out of the box way to set up running migrations against a specific database (e.g. development, test, production). The following adjustments to its env.py and alembic.ini allow us to target a specific database:

Example:

alembic -x db=development upgrade head

env.py:

	# /usr/bin/env python
	# Based on https://chuoi.org/posts/checkexchangeemailandsendemailwithpython/
	"""Description
	A Python script to check email exchange mailbox, download require attachment and send email to user.

	Use:
	cd /path/to/file && python3 main.py

	import os

	import string
	import unicodedata

	INVALID_FILE_CHARS = '/\\?%*:\|"<>' # https://en.wikipedia.org/wiki/Filename#Reserved_characters_and_words

	def secure_filename(filename):
	# keep only valid ascii chars
	output = list(unicodedata.normalize("NFKD", filename))

	# special case characters that don't get stripped by the above technique

	# test_camera.py
