·体系结构框架（ArchitectureFramework）是一种规范化的体系结构描述过程和方法，确保各利益相关方基于统一标准对体系结构进行理解、比较和集成。
·从多个视图以及不同抽象层次上对体系结构加以捕获，将复杂的问题域划分为便于管理的模块，使得利益相关方对整体有宏观把握的同时，可以关注于特定方面。

VisualizingData:ExploringandExplainingDatawiththeProcessingEnvironmentPaperbackbyBenFry这是一本关于计算信息设计的书籍。
从如何获取原始数据开始，到如何理解原始数据，本书都作了非常详尽的介绍。
书中使用由作者开发的开源编程环境Processing编程，它非常简单易用。
对于熟悉Java的程序员来说，本书后面的章节还介绍了如何将Processing和Java结合使用。
本书是写给那些拥有一个数据集合，好奇如何探索它，并且考虑如何交流这些数据的人们的。
随着我们处理越来越多的信息，需要可视化数据的人的数量增长非常迅速。
更重要的是，读者已经超越了某些可视化领域的专家。
通过让更大范围的人接触到可视化思想，在接下来的几十年中应该可以看到一些真正让人惊叹的成果。
BenFry在麻省理工多媒体实验室Aesthetics+ComputationGroup获得了博士学位。
他是卡内基•梅隆设计学院2006~2007年度NierenbergChairofDesign的客座教授。
他同CaseyReas共同开发了Processing，在2005年获得了PrixArsElectronica的GlodenNica奖项。
Ben的作品获得了Rockefeller基金会的NewMedia奖学金，并且展示在现代艺术博物馆，ArsElectronica，2002年的WhitneyBiennial，以及2003年的CooperHewittDesignTriennial中。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
