U8String的重构体会

     摘要: 近两年来在写C++的运行时环境,反射、运行时类型信息、内存管理、并行、字符串、协程、ORM等等,基本上重写了一套标准库以及运行库。对于在c++下使用字符串,深有体会。一开始呕心沥血,殚精竭虑,支持多种编码方式(Utf8、Utf7、GB2312、Utf16LE,Utf16BE等)的字符串类型,以及在此之上的对这些字符串提供格式化、字符串解析、json、xml、文件读写BOM等等功能,必须承认,大C+...  阅读全文

客户端UI层设计的思考

     摘要: 貌似现在流行知乎live和微信公众号, 博客已经有些过时了,但关键是你对技术的思考和总结, 采用什么方式其实不重要。
(1) 界面和逻辑的分离, view和controller可以由不同的人分别实现, 独立变动
(2) 基于接口分层设计, 单向依赖且低耦合
(3) UI层数据类型的分类,共有共享的还是私有的
(4) 消息中心,同时支持同步/异步的消息广播机制, Manager/Controller/Data Model可以各自订阅自己感兴趣的消息  阅读全文

Virtual Reality: Immersive Yourself In Your 3D Mockup

 Virtual Reality: Immersive Yourself In Your 3D Mockup

ESI's Virtual Reality software solution IC.IDO is an exceedingly powerful immersive engineering solution combining high-end visualization and real-time simulation of product behavior in its actual size, and allows product operation very close to reality.

 

Major companies from the manufacturing industry (aerospace, ground transportation, industrial machinery) use IC.IDO VR software to perform collaborative and immersive design reviews, to evaluate and optimize assembly and disassembly sequences, to verify resources and tooling for both manufacture and maintenance, to support documentation and workflow animation/ training. IC.IDO detects contact and obstruction during assembly and maintenance procedures, and enables instant evaluation of flexible components such as pipes and cables.

想当年,360

想当年,我360云盘,还有几个T的电影下载不下来,说好了,给时间让我们备份,结果速度只有100k,还没事老断,不能接着下载
想当年,360搞手机,把酷派的大神收过去,说好的,给我们升级OS,然后就没有下文了
想当年,我编译一个程序,它报一个大大红叉,然后把我编译的程序删除了
想当年,3721这个是周神棍写的
想当年,3721被卖掉后,灭3721的也是它
想当年,3721是软件安装困绑的鼻祖
来三枝香,给360上上

Qt源码编译

     摘要: Qt源码编译 eryar@163.com Key words. Qt, 源码编译 1.Introduction 随着Qt版本升级,源码编译出来的库体积越来越大。如果只是用Qt来做GUI,Qt提供的预编译库中有很多很功能不会用到,所以如果自己从源码编译Qt,一是可以只使用自己程序用到的功能,使自己发布程序的体积尽量小;还有如果对GUI开发感兴趣,就可以自己对源码进行Debug。本文记录一下从...  阅读全文
