Setting up RetroPi + iBuffalo SNES controllers
View gist:b4f26a947c52ba31940c
The documentation online can be confusing, especially with config paths from old files floating around.
1. Download an image file for RetroPi (Ideally 2.5+)
2. Unzip the image file, plug in your SD card (likely /dev/sdb)
3. dd if=retropi.img of=/dev/sdb (this will erase your entire SD card)
4. Optional: increase the size of the new partition with gparted
System Setup
1. Add your ROMs to ~/RetroPi/roms/snes (which will cause your EmulationStation to now show the system in the menu). Be sure to unzip them.
2. (Not needed in RetroPie 2.5) Update your controller config, either by running ~/retropi_setup/retropi_setup.sh, or copying a known config to /opt/retropie/emulators/RetroArch/USB,2-axis8-buttongamepad.cfg

ffmpeg split video
View ffmpeg-split.md
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

Kata Practice

Sum of all multiples of 3 or 5

Given an integer, write a function findSum that returns the sum of all multiples of 3 or 5 up to up to n.

findSum(8) returns 5 findSum(33) returns 10

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
View postgres-upgrade.md

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

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).
