Loïc Faugeron continues his series of "Mars Rover" posts with this new article focusing on a refactor of the currently defined method of "driving" the rover.

In this series we're building the software of a Mars Rover, according to the following specifications. It allows us to practice the followings: Monolithic Repositories (MonoRepo), Command / Query Responsibility Segregation (CQRS), Event Sourcing (ES) [and] Test Driven Development (TDD).

We've already developed the first use case about landing the rover on mars, and we've started the second one about driving it. [...] In this article we're going to refactor DriveRover

He points out the reason for the refactor: there could be a desire to have more that one driving instruction in the list to execute. He starts by using phpspec to define the "Instruction" class and some tests to ensure the different directions are handled. He then moves over to the "Instruction" test and moves the code from the "DriveRover" class into it, including the valid driving directions.

In this new post to his Oracle blog, Christopher Jones mentions some updates he's made to the OCI8 extension for PHP:

I've merged connection pooling (DRCP) and Fast Application Notification (FAN) support to PHP 5.3's OCI8 extension. The PHP 5.3 OCI8 code is Beta - in fact, PHP 5.3 itself is still really "Development". (It would be handy to have problems reported before PHP 5.3 goes Production).

He also includes instructions on how to get this new version installed inside of the latest PHP 5.3 snapshot (http://snaps.php.net) to build the new support in.
