"Instantly" Understand U.S. Monetary Policy

Well, maybe. If any of this is confusing, see the Resources section at the bottom.

U.S. Economic Policy In A Nutshell

Quick terms (might differ a bit from other sources):

• "T-bills"/"treasuries"/"bonds" (there are multiple types) = a promise (from the US government) to repay an amount of cash at a specific future date, with interest. These are not intended to be used as money to buy goods/services, but are a mechanism for "the fed" to manipulate interest rates, the amount of cash flowing through the economy, and the amount of cash that the government has to spend on things.
• "Reserves" = cash (typically cash that a bank actually has).

Elm in Node (0.17)

Why?

Sharing code between the client and the server in a Universal Javascript application is a big gain. No more are the days of rewriting code for the server.

But moving from Javascript to Elm in the front end can feel like a move backwards. So much of the code we write is environment independent. And it would be great if we could leverage some of the front end logic on the backend.

How?

This cheat sheet contains lists of 'Hoon' words and symbols and short descriptions of what they are or what they do. Note that we unabashedly map Hoon concepts to the closest corresponding concept in other programming languages, even if the concepts are not quite the same. For example, in biology, [http://evolution.berkeley.edu/evosite/evo101/IIC1Homologies.shtml bird wings and bat wings are said to be analogous but not homologous], because they have similar function but they are not quite the same and indeed the common ancestor of birds and bats did not have wings. In this table, we map analogous concepts to each other even if they are not homologous; if bat wings and bird wings were here, we would map bat wings to bird wings. For example, we map 'gate' to 'function; see the section "Gates and lambda" from [http://doc.urbit.org/doc/hoon/tut/4/ Hoon tutorial section 4] for more discussion of this.

Please note that i am writing this in the process of learning Hoon, and i don't understand most of what is writt

/**
 * Base contract that all upgradeable contracts should use.
 * 
 * Contracts implementing this interface are all called using delegatecall from
 * a dispatcher. As a result, the _sizes and _dest variables are shared with the
 * dispatcher contract, which allows the called contract to update these at will.
 * 
 * _sizes is a map of function signatures to return value sizes. Due to EVM
 * limitations, these need to be populated by the target contract, so the
 * dispatcher knows how many bytes of data to return from called functions.
