“称职”包括两个意思：完全了解客户的需求，具备敏捷和Scrum的实用知识。第二点包括能够实行相关的实践，例如准确填写和修改产品的backlog，或以用户故事的形式描述需求。

DRN-TV与Billy Hollis进行了一次精彩的对话与演示，谈论了在WPF与Silverlight上开发的下一代商务应用。Billy与他的客户共同合作，提供了一个为临时工寻找合适的工作职位的平台。目前这个应用是创建在WPF上的，不过他们目前正在计划创建Silverlight的版本。请观看这个包含了完整演示内容的web cast。

这些是我觉得很酷的东西：

1. 他们有效地通过界面上的提示信息来引导用户的注意力（比方说针对每个实体模型的弹出框）。
2. 他们的多模块的编辑模式，可以同时编辑多条记录。良好的导航与通告功能充分地支持了对这种编辑模式的管理。
3. 看起来很好地实现了脏跟踪（dirty tracking）。

Billy, 我们都盼望着尝试一下实际的产品呢！

面向商业应用的一个非常通用的模式是“Composite Application Pattern”（组合应用模式）。在过去的几个月中，我们的P&P（Patterns & Practices）团队与业界的领导者与Microsoft的生产团队合作，为创建WPF composite application的创建推出了一个示例应用以及一个框架。

如果你正关注于创建一个面向商业的WPF应用，你真的应该查看一下这个……它包含了所有的文档、源码甚至是单元测试！

【原文地址】Very Simple .NET Thumbnail Creation Code

【原文发表日期】10 July 08 09:15

当我在更新我的Ajax示例的时候，我需要为某个目录下的图片创建缩略图。可用的工具实在是多不胜数，不过我还是想分享一下我所使用的一段非常简单的代码。

这段程序会提取根目录下的所有jpg文件，为它们创建160*120的缩略图，并将图片拷贝到完整路径下。

namespace ThumbNailer
{
    class Program
    {
        static void Main(string[] args)
        {
            string rootPath = @"C:\Users\brada\Desktop\ForDemo";
            string thumbPath = Path.Combine(rootPath, "Thumb");
            if (Directory.Exists(thumbPath)) DirectoryDelete(thumbPath);
            Directory.CreateDirectory(thumbPath);

            int imageNumber = 0;
            foreach (string s in Directory.GetFiles(rootPath, "*.jpg"))
            {
                imageNumber++;
                Console.WriteLine("{0}:{1}", imageNumber, s);
                Image i = Image.FromFile(s);
                Image thumb = i.GetThumbnailImage(160, 120, null, IntPtr.Zero);
                thumb.Save(Path.Combine(thumbPath, GetName(imageNumber)));
            }
        }

        static void DirectoryDelete(string directoryName)
        {
            foreach (string filename in Directory.GetFiles(directoryName))
            {
                File.Delete(filename);
            }
            Directory.Delete(directoryName);
        }
        static string GetName(int imageNumber)
        {
            return String.Format("{0}.jpg", imageNumber);
        }
    }
}

更新：有些人问我如何在ASP.NET中实现……Bertrand有一个完整得多的例子在此：

The graphics in Google"s 3D chat world Lively shine, but behind the scenes the Lively team also seems busy squashing minor and major early-release bugs. And since some days, Lively got its first social phenomenon, too: the almost meme-like creation of cyber sex rooms. Not that there"s anything wrong with that, or is there? To see what Google thinks let"s ask Lively"s community guidelines, which state: We don"t allow nudity, graphic sex acts, or sexually explicit material. This includes making sexual advances toward other users. We also don"t allow content that drives traffic to commercial pornography sites ... However, a typical room overview listing at Lively.com lately revealed ...

Radiohead teamed up with Google to show their music video for the song "House of Cards," visualized using 3D data. Google also offers an interactive app to let you see this data (it may take some time to load but once it"s done, you can play the video and pan & zoom at the same time), a Making Of, and a download of the points data as Comma Separated Values file.

The JavaScripted SWFObject is a popular way to include Flash files. Recently, Google announced better support for crawling Flash files, and in an update they added to their original post, they now also say: For our July 1st launch, we didn"t enable Flash indexing for Flash files embedded via SWFObject. We"re now rolling out an update that enables support for common JavaScript techniques for embedding Flash, including SWFObject and SWFObject2. On another note, Google adds: At this time, content loaded dynamically from resource files is not indexed. We’ve noted this feature request from several webmasters -- ...
