This is an informal list of TODOs and nice ideas for the Tilck project.

-
S = Size (1-10)
- 1 means less than 100 LoC
- 2 means up to hundreds of LoC
- 3 means 1-2k LoC
- 4 means 2-3k LoC
- 5 means at least 3-4k LoC
- 8 means at least 7-8k LoC, hopefully less than 10k
- 10 means at least 10k-15k LoC or more

C = Complexity (1-10), for an experienced kernel engineer (L4-L5 level).
- 1 means trivial
- 2-3 means simple
- 5-6 means medium
- 7 means challenging
- 8-9 means difficult
- 10 means extremely difficult
For non-kernel engineers, it's totally non-obvious how to do determine the complexity of a task. It depends a lot on the particular profile of the person. Generally speaking, the subjective complexity of a task raises when the person is less experienced. For example, depending on the person, a simple or medium task might be perceived subjectively as difficult.
