Via Ars Technica: "Former One Laptop Per Child (OLPC) security director Ivan Krstic is mad as hell and he's not going to take it anymore. He opened up a massive can of damning allegations about OLPC earlier this week in a lengthy tirade on his personal blog. The blog post includes a deeply pessimistic appraisal of constructionist learning theories and some harsh words for OLPC founder Nicholas Negroponte, but it also offers some valid and insightful observations about the project's failings and what can be done to remedy them."
