Above, Lazarus 0.9.30-0 + FPC 2.4.2 editing Rednaxel's ERP, RNGE 3, running on Windows XP (32-bit). Below, the same screenshot -- same project, same source code -- taken on Ubuntu 10.10 (32-bit).
This blog describes the porting of a medium-sized application (~250 kloc) from D7 to Lazarus. It uses PostgreSQL as database, and the connection is being ported from DB Express (D7) to SqlDB (Lazarus).

The "price check" terminal mentioned in a former post was incorporated to RNGE3. Right now we're developing the next-generation SCM (Supply Chain Management) module; instead of a mere port, it's a major overhaul. We'll read the supplier's invoice directly from his NFe's XML, saving a huge time in the inventory control process.
