Introduction

Constraints

Since a large percentage (if not the majority) of Karma users are envisioned to be using OLPC XO-1 laptops, netbooks, older hardware or generally relatively slow systems there are several performance constraints that need to be taken into account when designing Karma lessons.

  • CPU/Memory:
  • Display: Karma lessons should work well on displays with a resolution of 1024*768 (whereby a part of the display may be taken up by browser UI elements!).
  • Mass storage: Since especially the XO-1 laptop only has very limited local mass storage (1GB) lessons should be kept reasonably small.
  • Connectivity: Karma lessons must not assume constant connectivity with a locally (e.g. XS) or globally available server. Support for storing data locally will be provided by Karma.
