Development #16

Provide a print style sheet

In addition to the benefits for the user, this style sheet reduces the number of pages printed, and therefore indirectly minimizes the website’s ecological footprint. It should be as streamlined as possible and employ an ink-light typeface e.g. Century Gothic. Also consider hiding the header, footer, menu and sidebar, as well as deleting all images except those needed for content.

Development #64

Cache the bytecode

Bytecode (called opcode for PHP) is the binary code generated from the source code. Some accelerators are able to cache bytecode, which avoids needing to recompile it from the source code every time. Less time spent compiling equals less CPU and RAM used.
