We welcome anyone who is eager to continue to contribute to the DataSketches mission of providing open source, production quality sketch algorithms and become part of our team. Please send us a message on [dev]({{page.dev}}) where we can give you some guidance. After you have made some successful contributions, the current committers will discuss your candidacy for becoming a committer. You can also review the [Apache policies on becoming a committer](https://community.apache.org/contributors/index.html) as well as our [New Committer Process](https://datasketches.apache.org/docs/Community/NewCommitterProcess.html) for selecting and inviting a committer to join our project.
### Reporting Security Issues
-If you wish to report a security vulnerability, please contact [security@apache.org](security@apache.org). Apache DataSketches follows the typical [Apache vulnerability handling process](https://apache.org/security/committers.html#vulnerability-handling).

### Comparison with Apache DataFu
-[DataFu](https://fdatafu.apache.org) is an Apache project that includes a set of Pig UDFs for various data processing purposes.
+[DataFu](https://datafu.apache.org) is an Apache project that includes a set of Pig UDFs for various data processing purposes.
Because the focus of the Sketches library is on sublinear or bounded-size algorithms, compared the performance of our reservoir
sampling Pig UDF against DataFu's basic reservoir sampling, which uses a pre-specified maximum size.
