If you have a Core 2 Duo Macintosh, the built-in WLAN card is capable of networking using (draft 2) 802.11n. This capability can be unlocked via an update Apple distributes with the new AirPort Extreme Base Station. Or, they will sell it to you for $4.99. Why don't they give it away for free, say with Software Update? Because of the Sarbanes-Oxley Act (which was passed in the wake of the Enron scandal). iLounge quotes an Apple representative: "It's about accounting. Because of the Act, the company believes that if it sells a product, then later adds a feature to that product, it can be held liable for improper accounting if it recognizes revenue from the product at the time of sale, given that it hasn't finished delivering the product at that point."

lizzyben writes "Baseline is running a long piece about the inner workings of MySpace.com. The story chronicles how the social networking site has continuously upgraded its technology infrastructure — not entirely systematically — to accommodate more than 26 million accounts. It was a rocky road and there are still hiccups, several of which writer David F. Carr details here." From the story: "MySpace.com's continued growth flies in the face of much of what Web experts have told us for years about how to succeed on the Internet. It's buggy, often responding to basic user requests with the dreaded 'Unexpected Error' screen, and stocked with thousands of pages that violate all sorts of conventional Web design standards with their wild colors and confusing background images. And yet, it succeeds anyway."
