调试可能会是一个讽刺的实践。我们创建了各种任务来告诉我们的品脱大小的超级计算机代表我们来完成千差万别和不可估量的任务，但为了理解这些相同的程序，我们告诉计算机等等我们例如，假设我试图找出为什么我的应用程序里的UINavigationBar没有按我预计的显示。为了调查清楚，我可能会使用调试器来看看诸如我在导航栏上设置的UIColor实例，这东西到底是什么颜色？Hold 住！并没有试图找出如何将这些组件加在一起的办法。其实有一个更好的办法。自从版本 5 开始，Xcode 在调试器已经附带了快速查看显示。正如你可以在桌面上快速点击空格键来查看文件的内容，在 Xcode 中你可以用可视化的快速查看各种数据类型。在我们的color变量上按空格键立即给出了一个答案，你脑海中应该马上浮现起了需要 RGB 转化计算：同时，你还可以直接从代码的调试中调用快速查看。比如下面的方法，buildPathWithRadius(_:steps:loopCount:)。它创造了某种形式的UIBezierPath，但你已经忘了，而这段代码到底是否工作？funcbuildPathWithRadius(radius:CGFloat,steps:CGFloat,loopCount:CGFloat)->UIBezierPath{letaway=radius/stepsletaround=loopCount/steps*2 ...继续阅读 (31)

HTML5 概述HTML5 是 HTML 语言最受欢迎的版本之一，它支持音频和视频、离线存储、移动端、和标签属性等等。还提供了,,这样的标签来帮助开发者更好地组织页面内容。然而 HTML5 规范仍然没有最后定稿，并且它并不是一个真正意义上的语义标记语言。HTML6 展望你有没有曾经希望能在 HTML 中使用自定义标签？比如：使用来显示你的网站logo，还有使用来显示工具栏等等。我们经常使用和来组织页面，在 HTML6 里我们希望可以直接使用象和这样的自定义标签。和 XML 一样，HTML6 应该支持 namespace（命名空间），如：xmlns:xhtml=”http://www.w3.org/1999/xhtml”HTML6 代码样例：DOCTYPE htmlA Look Into HTML6a1a2Heading of main articleSub-heading of main article[...][...]The concept of HTML6Understanding the basics[...]This site is © to Anonymous 2014在上面的代码中，你也许注意到了一些奇怪的标签，它们是 W3C 和 HTML6 规范中在命名空间里定义的标签。例如：负责设定你浏览器的标题栏文字，负责显示图片等等。用户可以自己定义标 ...继续阅读 (19)

The low polygonal resolution was faster to render images in 3D. Most recently it has caught on as an illustration technique because of its versatility, simplicity and provides an unique ...继续阅读 (10)

blahblahblah,这几天看了三部电影，随便感慨下。Always Look on the Bright Side of Life也许执念太深，从一年前开始看到无所事事的人就极度不爽，也无法忍受自己浪费一分一秒，然而事情总是这样：你越想抓住什么，什么就越从你的指缝间溜走得越快。一年来总是给自己一些莫名奇妙的压力，天天为各种各样的琐事烦得一塌糊涂。结果身体一直也不好，要不要感冒每个月就像大姨妈一样来一次？1有很多人和事，只觉得他们二逼，然而搅扰的自己也无法静下心。也许只是我自己太在意。我想黑我们学校，黑自己专业，黑这学校很多人很久了。然而最终还是忍住，也许世界就该这样，或者你爱怎样就怎样。没必要因此搅扰得自己不安。也许我就该笑笑，依旧回头走我的路，如果路被人堵上，换另一条继续走，条条大路通罗马。也许我就该放下许多执念，在心灵上解放自我，在行动上自我解放。也许我就该随波逐流，无所谓得失，让该来的来，让该去的去，万事随缘。每天入夜，当我怨恨时，我不断暗示自己，神赐你一颗平和的心，不要怨恨。当我为周围的风吹草动胆颤心惊时，不断鼓舞自己，神赐给你的是一个刚强的心，无所畏惧。让心平和下来吧，一直想考研，跨掉自己的专业，离开熟悉的学校，寻找更好的环境和人2。但没必要逼自己，让心平和下来吧好好锻炼身体，考不上明年再来。再考不上再做打算。留得青山在，不怕没柴烧。总是看见生活光明的一面。some ...继续阅读 (14)

自Sun收购了MySQL AB 以来，虽然对于我们来说并没有看到Sun给MySQL带来太多实质性的改进和优化，但是从Sun官方目前在各种场合的表态可以看出他们还是比较重视MySQL这个数据库产品的。而且，Sun也保证了会一直保持MySQL的开源之路。收购了MySQL之后，Sun在整合MySQL和自己以前的软硬件产品方面也在不断的努力和尝试，看看下面这个视频中Sun为整合优化MySQL到自己的软硬件平台所建立的实验室吧，还是耗费了不少 $ 的，呵呵。 ...继续阅读 (11)
