How to disable systemd-resolved in Ubuntu

Stages

Disable and stop the systemd-resolved service:

  sudo systemctl disable systemd-resolved.service
  sudo systemctl stop systemd-resolved

Then put the following line in the [main] section of your /etc/NetworkManager/NetworkManager.conf:

Maven 3.8.1 blocked mirrors "fix"

This is not a fix, but a workaround for repositories not on HTTPS yet. Use with caution.

Error

[ERROR] (...) Could not transfer artifact no.whatever:whatever-client:pom:3.1 from/to maven-default-http-blocker (http://0.0.0.0/): Blocked mirror for repositories: [releases (http://unportected.com/nexus/content/repositories/releases, defaul)] -> [Help 1]

First, install the following libraries:

$ brew install unixodbc
$ brew install freetds --with-unixodbc

FreeTDS should already work now, without configuration:

$ tsql -S [IP or hostname] -U [username] -P [password]
locale is "en_US.UTF-8"

locale charset is "UTF-8"

systemd Service Unit for Traefik

Adapted from caddy systemd Service Unit

The provided file should work with systemd version 219 or later. It might work with earlier versions. The easiest way to check your systemd version is to run systemctl --version.

Instructions

We will assume the following:

	#Enable Gzip compressed.
	gzip on;

	# Enable compression both for HTTP/1.0 and HTTP/1.1.
	gzip_http_version 1.1;

	# Compression level (1-9).
	# 5 is a perfect compromise between size and cpu usage, offering about
	# 75% reduction for most ascii files (almost identical to level 9).
	gzip_comp_level 5;

	;; output example: "2022-11-25T08:30:05.417+00:00"

	(defn now->iso8601-str
	[]
	(let [tz (java.util.TimeZone/getTimeZone "UTC")
	df (new java.text.SimpleDateFormat "yyyy-MM-dd'T'HH:mm:ss.SSS'+00:00'")]
	(.setTimeZone df tz)
	(.format df (new java.util.Date))))

	;; other possible solution with "Z" instead of "+00:00" but(!) I don't like symbol "Z" anymore :-(
