He fixed it, compiled via the command line (the Carbide IDE was slow and crashed constantly), and watched the final .sis file—Symbian Installation System—appear in his project folder. It was 234KB. That file contained a web crawler, an XML parser, a media player controller, and a UI with softkeys. It was a cathedral of efficiency.
The .sis files are mostly gone now. The signing servers are dark. The forums are archived.

They were the last of the old world—written by developers who knew the color of every register and the shape of every heap cell, standing on the precipice of the app store revolution, unaware that their masterpiece was already a relic. symbian 9.1 apps
