Posterior visual bounds retrieval for the Plato framework

摘要：This article discusses an approach to the issues with the obtention of visual bounds of objects from view/view model side, including the unavailability of the view/view model and the impact on the functioning of the framework of Plato by violating its guidelines of usage. It introduces a modified sight manager with unified visual information support and how it's integrated with the existing system. 阅读全文

A Distributed Algorithm Exercise

摘要：This is one of the most daunting problems I have ever solved in my life. Another one with a similar complex nature that comes in to my mind is the extended regular expression parser I implemented. For the latter I still not 100% sure if it works perfectly as expected, it passed some typical tests th 阅读全文

WPF: Changing sizes of grid rows and columns during runtime

摘要：At work I spent a lot of time trying to get my head around a issue with WPF grid resizing during runtime. I always found the controls don't resize the way I wanted and differently than how those in the exemplary program (MS Office in this case) do.What I intended to do issomething like the recen 阅读全文

C#代码规范——成员分段

摘要：这里的基本整理一般原则是：1. 尽可能少分段2. 关于类的尽可能靠前（例如static），关于实际对象的尽可能靠后3. 早生成的尽可能靠前4. 公有的，接口的尽可能靠前5. 抽象的，通用的，基础性的，被依赖靠前；继承过来的尽量靠前6. 相对需要引起注意的尽量靠前7. 其他一些以往经验考虑 1 class Sample : BaseClass, IIntf1 2 { 3 #region Enumerations 4 5 enum EnumType 6 { 7 Const1, 8 // ... 9 } 10 11 #en... 阅读全文

一段写坏掉的快速DCT实现

摘要：想当然了，用递归实现DCT，没想到DCT有4个分支需要递归下去，这样的规模非但无法快速实现，反而由于本身时间复杂度没有多大减少加上递归开销等等比慢速实现往往还慢。这个代码片段将由于清洁需要从QSharp中删除而保留在这里，对其分析将在代码之后有空时进行。过两天想想是不是能用动态规划或备忘录来改进这个算法。 1 /// <summary> 2 /// Type-IV DCT implemented using recursive method 3 /// Warning: This method is mathematically crippled even slower than 阅读全文

算法题，做了近一天

摘要：原题出处，由July提供并解析，http://blog.csdn.net/v_july_v/article/details/8701148自己独立做，一开始方向有偏差。最后独立思路写了一个超容易出bug调了半天的O(n)：目前该程序至少在1000个以1~20长度以-20.0到20.0随机浮点数为元素的随机序列上和参考算法（穷举法）对比测试通过。public static double MPCSolveQb2(this double[] seq, out int start, out int count) { start = 0; count = seq.Length; ... 阅读全文

现在我是很反感C++这个语言

摘要：应当讲我现在是很不喜欢C++这个语言。不仅仅语言复杂，这其实倒也无所谓，但问题是：C++是“一次编写，到处编链（生成），各种编链不过”，这就是C++的真正特点。这两天弄那个Teigha的CAD文件处理库，很装x闭源的库（所以C++也更应提倡开源，开源你去解决编译问题，闭源你就去解决可能永远解决不了的链接问题去吧）加一些很装x的例子程序写了一大坨，每种平台和配置都做一个包，总大小好几个G，拿下来去升级整合原先的调用程序，折腾了两天最后运行还通不过。这种情况只要遇到调用第三方库就总会遇到，而且每次遇到就算情况再相似都会无谓耗费大量时间。所以可以讲C++是一种开发效率非常低下的语言。无尽的咒骂。。。阅读全文
