Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

These instructions are for implementing HTTPS on a NFSN-hosted static site using a certificate from Let's Encrypt. The certificate is generated manually on a separate computer.

Start off by installing the letsencrypt client. This requires sudo privileges and will install a bunch of packages:

% curl -O https://dl.eff.org/certbot-auto
% chmod +x ./certbot-auto
% ./certbot-auto

Generate the certificate. This will require you to publish some challenge responses on NFSN. I find it easiest to use tmux with letsencrypt running in one window and an SSH session to NFSN in another:

You got your hands on some data that was leaked from a social network and you want to help the poor people.

Luckily you know a government service to automatically block a list of credit cards.

The service is a little old school though and you have to upload a CSV file in the exact format. The upload fails if the CSV file contains invalid data.

The CSV files should have two columns, Name and Credit Card. Also, it must be named after the following pattern:

YYYYMMDD.csv.

Essential JavaScript Links

I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).

	# 1) Install binary as described in no-ip.com's source file (assuming results in /usr/local/bin)
	# 2) Run sudo /usr/local/bin/noip2 -C to generate configuration file
	# 3) Copy this file noip2.service to /etc/systemd/system/
	# 4) Execute `sudo systemctl daemon-reload`
	# 5) Execute `sudo systemctl enable noip2`
	# 6) Execute `sudo systemctl start noip2`
