PostgreSQL donates Database Replication software

PostgreSQL, Inc has announced that it has contributed version 1.0+ of its eRServer database replication software to the open-source community.

The company has a policy of relicensing its commercial software two years after its commercial release, eRServer has been made available one month ahead of that schedule. '*All* proprietary developments that we are involved in *will* become open source within two years of implementation, without exception."'

The eRServer software will be released under the BSD license.

The company's president, Marc Fournier warns of the possible difficulties involved with using the replication software, and suggests that users consider purchasing their commercial support. "replication can be an extremely complex area for programming in enterprise systems - so even the more advanced database users should expect to invest a good deal of development time and effort in properly deploying this software."

This will be a welcome addition to the arsenal of open-source database tools, the company should be commended for their actions.

Memoization in Java Using Dynamic Proxy Classes (O'Reilly)

Tom White discusses memoization in Java. "Memoization is a technique borrowed from functional programming languages like Lisp, Python, and Perl for giving functions a memory of previously computed values. Memoizing a function adds a transparent caching wrapper to the function, so that function values that have already been calculated are returned from a cache rather than being recomputed each time."

Recently I've encountered a design pattern (or antipattern, in my opinion) that threatens the very foundation of our enterprise. It's harmful and it has to stop."

Each metacharacter packs power and nuance, making code impossible to decipher without resorting to mental gymnastics."
