Falsehoods programmers believe about prices

1. You can store a price in a floating point variable.
2. All currencies are subdivided in 1/100th units (like US dollar/cents, euro/eurocents etc.).
3. All currencies are subdivided in decimal units (like dinar/fils)
4. All currencies currently in circulation are subdivided in decimal units. (to exclude shillings, pennies) (counter-example: MGA)
5. All currencies are subdivided. (counter-examples: KRW, COP, JPY... Or subdivisions can be deprecated.)
6. Prices can't have more precision than the smaller sub-unit of the currency. (e.g. gas prices)
7. For any currency you can have a price of 1. (ZWL)
8. Every country has its own currency. (EUR is the best example, but also Franc CFA, etc.)

Exposing a directory on the host machine to an LXC container

1. Log into the container and create an empty directory, this will be the mount point
2. Log out and stop the container.
3. Open to your container's config file
   • For regular LXC containers: /var/lib/lxc/mycontainer/config
   • For unprivileged LXC containers: $HOME/.local/share/lxc/mycontainer/config
4. Add a new line above the lxc.mount directive, that follows the format below. Substitute proper paths as necessary:
   • lxc.mount.entry = /path/to/folder/on/host /path/to/mount/point none bind 0 0

• Both of these paths are relative to the host machine.

Some resources that have helped me learn golang over the last 3 years. I taught myself golang, it was a lot of grinding initially but I went through with it because I really liked the simplicity yet ability to be bare metal.

Here are some resources that have helped me in my journey. Sharing them here in case anyone is looking for study materials. [Disclaimer: These are links/notes collected over 3 years and not necessarily in order of expertise, but I will try my best to order them starting from basic ones and moving to more advanced resources]

Firstly - https://golang.org/ and https://golang.org/doc/ .Learn straight from the gophers mouth.

https://www.udemy.com/share/1013gw/ - Todd Mcloeds Course which I completed. Lays a strong and solid foundation of the most important golang concepts. I hope hes been updating his course. Highly recommend.

Tip: I created a repo while following the course. Helped drill the concepts in. Feel free to use this or or make something similar as your learn.
