In economics, a public good is a good that is non-rivalrous and non-excludable. Non-rivalry means that consumption of the good by one individual does not reduce availability of the good for consumption by others; and non-excludability that no one can be effectively excluded from using the good [http://en.wikipedia.org/wiki/Public_good] | In economics, a public good is a good that is non-rivalrous and non-excludable.

Tuesday March 1
Key components:
- Distributed File System
- Can use something previously presented in class
- Distributed computation
- Administration
- How much does a person need to contribute to the system?
- How will users submit (small) services they would like to have run?
- How can very large services be established (from idea to implementation)?
Todo for March 8th:
- Find papers on distributed computation and administration
Thursday March 3
- Seek out papers on specific topic of distributed web cache.
- Discussed two other interesting public goods or services.
- Image registry
- DNA registry - found one article that suggests uncompressed the human genome is between 1.5 and 30 terrabytes but more efficient formats exist that bring it down to 1.5GB

One example paper Improving Web Server Performance by Caching Dynamic Data
Tuesday March 8
Currently our idea of public goods consists of:
- Distributed file storage
- Ceph seems to be an ideal candidate for this
- Distributed Computation
- To avoid a tragedy of the commons situation with both the storage and computation resources, only predetermined, agreed upon computation will take place which has a net benefit to everyone participating. This computation is based on the data stored at each node and the results (metadata) will be stored locally. This computation can be done by using idle cycles, much like BOINC projects.
- Must allow for querying of metadata to allow users to effectively search processed data.
- Maybe we need to also consider the movement of data between client machines to fully utilize available resources. For instance, let's assume that a given machine has a relatively low amount of available storage but a lot of free computation cycles. In this situation, once data has been processed it should be moved to a client machine with available storage and data from a machine with a relatively low a mount of free computation cycles should be moved to the original machine.
- Administration
- Main issue: how are services agreed upon? Once a service is implemented (ie. image store) distributing it getting it running isn't a major issue.
- Maybe users should submit potential services to be run on the stored data and "the system" should decide what to do. This could/should be done based on available computation cycles, amount of generated metadata and the overall "popularity" of the service.
- Papers that seems related to this issue:
- The Case for Distributed Decision Making Systems (old)
- Distributed decision making: a research agenda (old)
- A mathematical framework for asynchronous, distributed, decision-making systems with semi-autonomous entities: algorithm synthesis, simulation, and evaluation
- Distributed Decision Making: A Proposal of Support Through Cooperative Systems
- Discussion
- Why is a public good a good idea?
- What value
- Why is a public good a good idea?
What should be a public good?
- What brings value to everyone?
- Examples: Distributed DNS, Spam Filtering, Policing?

I kind of did a big overhaul on our page, moved all of the discussion items from the main page here and all of the main work over to the main page. Our main direction has changed considerably after a few conversations between us and Prof. Somayaji. In general we are moving away from the "how to do things" (implementation) and to the "why is it important/better that certain services are in the public's hands". This new direction is now outlined on the main page. Below is an additional note that I couldn't find a place for on the main page.
We are now thinking in analogy. We are trying to identify public goods that are analogous to real world counter parts. In the real world examples of public goods are roads, parks, police, military, water, sewer.

Discussion: Definition of Public Good
- Economic Definitions:
In economics, a public good is a good that is non-rivalrous and non-excludable. Non-rivalry means that consumption of the good by one individual does not reduce availability of the good for consumption by others; and non-excludability that no one can be effectively excluded from using the good [1]
A good that cannot be charged for in relation to use (like the view of a park or survival of a species), so there is no incentive to produce or maintain the good [2]
A good that is provided for users collectively, use by one not precluding use of the same units of the good by others [3]
A good or service in which the benefit received by any one party does not diminish the availability of the benefits to others, and where access to the good cannot be restricted. (Source: Millennium Ecosystem Assessment Glossary ) [4]
