Scala Migrations is a library to manage upgrades and rollbacks to database schemas. Migrations allow a source control system to manage together the database schema and the code using the schema. It is designed to allow multiple developers working on a project with a database backend to design schema modifications independently, apply the migrations to their local database for debugging and when complete, check them into a source control system to manage as one manages normal source code. Other developers then check out the new migrations and apply them to their local database. Finally, the migrations are used to migrate the production databases to the latest schema version. The Scala Migrations library is written in Scala and makes use of the clean Scala language to write easy to understand migrations, which are also written in Scala. Scala Migrations provides a database abstraction layer that allows migrations to target any supported database vendor.

Google Chrome OS is an open source, lightweight operating system that will initially be targeted at netbooks

Osmos provides on-disk ordered key-value tables for Erlang, based on a sort-merge machine with user-defined merging semantics. This allows a very high volume of updates to be handled efficiently while still supporting a variety of useful operations with transactional safety, e.g., adding to a counter, taking the union of sets, or simply replacing a record. Osmos is ideal for situations where updates are much more frequent than queries, for example, collecting statistics for reporting, and periodically generating reports.

ScalaTest is a free, open-source testing tool for Scala and Java programmers. It is written in Scala, and enables you to write tests in Scala to test either Scala or Java code. It is released under the Apache 2.0 open source license.

Stack Overflow is a collaboratively edited question and answer site for programmers – regardless of platform or language. It's 100% free, no registration required.

flatula is a simple "write-once" database for Erlang that provides an easy way to remember a piece of data, then look it up later using a compact identifier. See FlatulaHowTo for a brief introduction and tutorial.

Max is an application for creating high-quality audio files in various formats, from compact discs or files.

plists is a drop-in replacement for the Erlang module lists, making most list operations parallel. It can operate on each element in parallel, for IO-bound operations, on sublists in parallel, for taking advantage of multi-core machines with CPU-bound operations, and across erlang nodes, for parallizing inside a cluster. It handles errors and node failures. It can be configured, tuned, and tweaked to get optimal performance while minimizing overhead.

More abstraction and generalization is not always better. In the Java library, the separation of the Calendar class seems like a nice abstraction, but it was not implemented well. The result is that the great majority of applications that use conventional calendars have to deal with cumbersome constants because Calendar attempts to make no assumptions about the breakdown of time into years, months, days, and so forth, resulting in verbose, unreadable code.
