| -- | |
| -- Inspriration: | |
| -- https://aws.amazon.com/blogs/database/multi-tenant-data-isolation-with-postgresql-row-level-security/ | |
| -- However the AWS example is a bit more complicated because they want each user | |
| -- to be identified by a UUID probably for management purposes. This demo | |
| -- presents a much simpler alternative for low numbers of users or environments. | |

| -- Assumptions: | |
| -- * An empty Postgres 12 database (older versions up to 9 may work but I have not tested them) |
| # Example Event Sourcing aggregate implementation in Elixir | |
| # | |
| # This is literally the first code that I wrote with Elixir. | |
| # So this may not be optimal or idiomatic Elixir. | |
| # | |
| # Note that I heavily use Elixir's pattern matching features. | |

| # Run with: | |

| # Invert Anker A7726 Keyboard FN Keys | |
| # | |
| # This is the keyboard I bought: | |
| # https://www.amazon.co.jp/gp/product/B00U260UR0/ | |
| # But the fn keys default to media keys which is very annoying. | |
| # | |
| # This will make the FN media keys function as F keys without pushing the FN | |
| # button. Also you can still use the media keys by pushing the FN + Media key | |
| # combination. | |

The guide at https://github.com/yepher/littlebits/blob/master/CloubitFileSystem.md is mostly correct but has a few mistakes. Luckily I found this page in Japanese http://qiita.com/chobie@github/items/d41cfa2d60df5d7d1a3f (and I can read Japanese) to point me in the right direction for the right way to do this.
Note: I used an Ubuntu linux machine to mount and edit the microsdcard.
You should also make a backup image of the SD card just in case.
