Below is a list of commands and resources that work on Linux (some need installation of packages), would love to welcome contributions for the same for MacOSX and Windows platforms too. Please share and contribute back.
Please run the below in both vagrant, docker and other container environments and share your experiences with us!

| Memoization is fundamentally a top-down computation and dynamic | |
| programming is fundamentally bottom-up. In memoization, we observe | |
| that a computational *tree* can actually be represented as a | |
| computational *DAG* (the single most underrated data structure in | |
| computer science); we then use a black-box to turn the tree into a | |
| DAG. But it allows the top-down description of the problem to remain | |
| unchanged. | |
| In dynamic programming, we make the same observation, but construct | |
| the DAG from the bottom-up. That means we have to rewrite the |
