gondaba writes "The One Laptop Per Child project is actively recruiting hackers to help crack the security model of the $100 laptop to avoid the obvious risks associated with what will effectively be the largest computing monoculture in history. From the article: 'The key design goal, Krstic explained, is to avoid irreversible damage to the machines. The laptops will force applications to run in a "walled garden" that isolates files from certain sensitive locations like the kernel. "If we discover vulnerabilities, the security model must hold up enough that even a machine that is unpatched won't be easily exploitable. This gives us a bit of diversity to avoid the monoculture trap," he added.'"
