Replacing legacy certbot-auto with docker

Replacing existing certbot-auto installation on Ubuntu 14 with Docker

The problem: Legacy certbot-auto is no longer supported, and ACMEv1 challenge has been deprecated and removed. On newer systems, you can simply upgrade certbot using apt-get install --upgrade-only certbot and you'll be good to go.

However, on legacy servers (Ubuntu 14), it isn't possible to upgrade. Installing manually isn't good either because python3 uses python3.4 which has a broken pip installation (ugh).

Docker to the rescue!

Upgrading Postgres from 12 to 13

I have no idea how but postgres was upgraded to 13, but the database was still in 12, so it wouldn't boot.

This URL saved the day: https://quaran.to/Upgrade-PostgreSQL-from-12-to-13-with-Homebrew

brew services stop postgresql
brew postgresql-upgrade-database
./analyze_new_cluster.sh
brew services start postgresql
ps ax | grep postgres

ffmpeg split video 
ffmpeg -ss 00:00:00.000 -i turtle.mkv -t 00:45:00.000 -c copy out.mkv

To cut out a section, just split it before and after the section to cut, then create a file with the filenames in it and run concat:

:: Create File List
echo file file1.mp4 >  mylist.txt 
echo file file2.mp4 >> mylist.txt
echo file file3.mp4 >> mylist.txt

Up and running with dotnet

Notes from early experiments with dotnet on Mac OSX

Installation: dotnet and VS Code

Installation was amazingly easy. < 2 minutes and dotnet is available from the command line.

Don't forget to install the c# plugin for VS Code (powered by omnisharp).
