Windows "Longhorn", 2002年微软决定开发的这个Windows XP未来的升级产品, 包括了称之为Palladium的全新安全体系, 硬件级3D加速的用户界面, 全新的基于数据库后台的存储系统..等种种新的特性.
Q: Longhorn会发行什么版本?
A: 是的, 像Windows XP一样, Longhorn 也将发行 Home Edition, Professional Edition, Tablet PC Edition, Media Center Edition, AMD-64, Itanium, 和可能的其他版本. 微软曾提醒一些版本的名称在将来的时候可能会有改变.
A: In the technology generations leading up to Longhorn, Microsoft has been moving to a .NET-based managed code environment dubbed WinFX, and the Longhorn generation will finally mark a clean split with the Win32 APIs of the past. That is, Win32 will be in maintenance mode, and all new development will occur with WinFX managed APIs. One such API, Avalon, forms the basis for the new Desktop Compositing Engine (DCE) in Longhorn that replaces GDI and GDI+. These and other new Longhorn APIs will utilize the XML Application markup language (XAML) to make Longhorn more accessible to developers than ever before. The idea is to significantly reduce the number of APIs and make the APIs more standardized. Today, there are over 76,000 Win32 APIs, and countless wrappers. With Longhorn, Microsoft hopes to reduce the API set to 8,000 to 10,000.
Another significant change in Longhorn involves device drivers. In the past, Microsoft allowed customers to use non-signed drivers, which helped compatibility, but caused stability problems. No more: In Longhorn, users hoping to take advantage of the system's exciting new capabilities will only be able to use signed drivers.
Developers interested in Longhorn should examine the Visual Studio .NET "Whidbey" release, currently in beta, and the Longhorn SDK. which includes developer-accessible UI components and behaviors.
Q: 看起来 Longhorn 和以前的 WIndows 相比有了很大的变化, 那么我现有的应用程序还能在新的操作系统上面运行吗?
A: 可以. MS 已经保证在 Longhorn 中将保持下至 DOS 的兼容. 尽管现在还不清楚 Longhorn 的 DOS 兼容性是否会在 Windows XP 中的糟糕的 DOS 兼容性上有所改善.
Q: 什么是 Palladium ?
A: Windows Longhorn 中的一大亮点就是可选的Palladium集成, 现在称为 Next Generation Secure Computing Base (NGSCB) 基于一个安全的运行环境, 应用于Windows和其他的操作系统, 允许将来的应用程序和软件来保护最终用户免受入侵, 外部黑客, 垃圾干扰以及种种其他类型的信息攻击.
● Palladium 的隐私保护. Palladium 也封装发送出去的信息, 它使用软件代理来确保数据通过Internet发送到正确的接收者. NewsWeek 曾报道这些代理在MS被命名为类似"My Man", ".NET My Services", "My Documents" 之类的名称.
● Palladium 还可控制发送出去的信息. 通过使用Digital Rights Management (DRM) 技术, Palladium 可安全的在Internet上发布音乐,电影和其他的有版权保护的信息和数据. 媒体发行和录制等组织可使用此技术使客户公平合法的复制音乐CD和电影. Bill Gates 曾提到: "It's a funny thing, We came at this thinking about music, but then we realized that e-mail and documents were far more interesting domains." 他指出 Palladium 可确保邮件被私有的指定从而不会被转发或者复制到其他的人. 引用NewsWeek的报道:"你可以建立一个Word文档, 使这个文档只能在下周被阅读, 甚至你可以指定一个特定的用户, 而不是MS, 这个规则的制定者"
Q: Longhorn 将于什么时候发布?
A: 非官方信息: 至少要到 2005 晚些时候.
Q: Longhorn 将于什么时候开始Beta测试?
A: 2004年夏天. MS最近在Los Angeles 的 Professional Developers Conference (PDC) 上提供给程序员一个早期的Alpha测试版本的 Longhorn (build 4051)和Longhorn SDK, 并于11月12日在MSDN上提供给MSDN订户.
