给 iPhone 举办葬礼的微软，图片来自 Rare Historical Photos更致命的是节奏问题。Windows Phone 7 在 2010 年才发布。那时 iOS 已经迭代了三年，Android 也进入高速扩张期。微软不是慢了一小步，而是直接错过了起跑线。当 iOS 推出 Siri（2011），Android 推出 Google Now（2012）时，Cortana 要到 2014 年才姗姗来迟。在移动互联网的时代「快」未必一定赢，但「慢」几乎一定输。
Tom describes starting out as a successful young analyst with a three-year investment horizon—until one quarter of losses changed everything. His boss shut the door and said they now needed “shorter-term opportunities to make money every month or we may not survive,” which Tom now sees as the moment the scoreboard reset from three years to 30 days. “It was a very ambiguous message,” he says, adding that he never asked, “Are we talking about what everybody else is doing or are we going to stay within the legal or ethical guardrail?” That combination of performance pressure and fuzzy instructions created an environment for Tom to begin thinking outside the boundaries of what he knew was right.，更多细节参见同城约会

The main rule for data access is max(CPL, RPL) ≤ DPL. For code transfers, the rules get considerably more complex -- conforming segments, call gates, and interrupt gates each have different privilege and state validation logic. If all these checks were done in microcode, each segment load would need a cascade of conditional branches: is it a code or data segment? Is the segment present? Is it conforming? Is the RPL valid? Is the DPL valid? This would greatly bloat the microcode ROM and add cycles to every protected-mode operation.。业内人士推荐WPS下载最新地址作为进阶阅读
