## Upload Strategy Of Happiness
The *Servers of Happiness* criterion is already in place for deciding whether a given distribution of shares over servers satisfies the user's requirements for fault-tolerant distribution. However, the algorithm that decides what shares to upload to which servers is not optimized to always satisfy the Servers of Happiness criterion. [Kevan Carstensen's master's thesis](https://zooko.com/uri/URI%3ADIR2-RO%3Aoljrwy5i2t3dhcx5mzrksegehe%3Axtac4ubcnr5eqo6d7h4wyj5sm522olj4mthizz2i3lfw2b5nla6q/Latest/compsci/Carstensen-2011-Robust_Resource_Allocation_In_Distributed_Filesystem.pdf) explains the context in great details and proposes an *Upload Strategy of Happiness* algorithm for allocating shares to servers. Implementing the *Upload Strategy of Happiness* should close the following tickets: #610, #1124, #1130, #1293, #1382, #1814.

## Advanced Cap Types
The current set of cap types is described on [Capabilities](Capabilities). There are several proposals for extended semantics: revocable write-caps (#945), a secure "301 Moved Permanently" redirect (#958), add-only sets (#795), write-only caps (#796).
