“姑娘,别这样.我们是有原则的.” “一个有原则的程序猿是不会写出 “摧毁地球” 这样的程序的,他们会写一个函数叫 “摧毁行星”而把地球当一个参数传进去.” “对,是时候和那些只会滚键盘的麻瓜不同了,我们可是有高逼格的程序猿.” [小九的学堂,致力于以平凡的语言描述不平凡的技术.如要转载,请注明来源:小九的学堂.cnblogs.com/xfuture] 写代码其实就是给一个世界创造秩序,世界越大就越需要原则,各司其职,统筹合作自然是比无脑的积木堆积星球来的令人信服,部分基于SOLID archi…

相当长一段时间以来,大数据社区已经普遍认识到了批量数据处理的不足.很多应用都对实时查询和流式处理产生了迫切需求.最近几年,在这个理念的推动下,催生出了一系列解决方案,Twitter Storm,Yahoo S4,Cloudera Impala,Apache Spark和Apache Tez纷纷加入大数据和NoSQL阵营.本文尝试探讨流式处理系统用到的技术,分析它们与大规模批量处理和OLTP/OLAP数据库的关系,并探索一个统一的查询引擎如何才能同时支持流式.批量和OLAP处理. 在Grid Dy…

一年开发ASP.NET MVC4项目所用所学技术经验总结 阅读目录 文章背景 前端所用技术摘要 后端所用技术摘要 1. 文章背景 本人2014年从Java转行到C#从事BS项目的开发,刚开始接触的是ASP.NET WebForm,结果对于我这种从jsp+servlet时代的人非常的不适应,开发者不能自由的操作HttpContext及其原始的Web命名空间中的类库来开发,而是全部封装成基于事件的机制来操作,非常的别扭.后面就找到了ASP.NET MVC这个框架.发现不错,而且从Java Web方向…

TOGAF架构能力框架之架构合同.成熟度模型和架构技能框架 5. 架构合同 架构合同是在开发团体和赞助者之间关于架构的交付物.质量以及适用目标的联合协议,并且通过有效的架构治理将会促使这些协议的成功施行.通过对合同的管理施行一个治理方法,如下几点将会得到保障: 一个连续监测系统,用于检查完整性.变更.决策,并对组织内所有架构相关活动进行审计. 与现存的或正在开发中的架构相关的原则.标准和需求得以被坚持. 明确存在于架构的开发.实现和运营中的各种风险. 一系列流程和实践得以被制定,从而保障针对所有…

3. 架构交付物(Architecture Deliverables) 架构交付物是在整个架构开发方法循环过程中所产生或被使用的契约性且正规化的企业架构内容,因而其与企业架构开发方法有着紧密的联系.本章将针对这些架构交付物以及他们与架构开发方法各阶段之间的关系进行阐述,不过需要注意的是,本章节的内容只是为了提供一个关于架构交付物的内容概括,由于企业中可能存在着符合其自身需要的项目和过程管理方法,因而企业也可以根据自己的实际情况对这些交付物进行改造和定制.首先,我们先来审视一下架构交付物与企业架构…

代码也需要有秩序,就像世界需要秩序,基于SOLID architecture principles. 一.SOLID原则 S.O.L.I.D.是一组面对面向对象设计的最佳实践的设计原则.术语来自Robert C.Martin的著作Agile Principles, Patterns, and Practices in C#,代表了下面五个设计原则: (1)SRP(Single Responsibility Principle): 单一责任原则: (2)OCP(Open Closed Princi…

Linux has supported a large number of SMP systems based on a variety of CPUs since the 2.0 kernel. Linux has done an excellent job of abstracting away differences among these CPUs, even in kernel code. One important difference is how CPUs allow memor…

成为一名资深架构师首先要懂设计模式,在懂之前,要清楚设计原则,原来我就吃过这个亏,很久以前有人问我设计原则,我是一头茫然,不是只有设计模式吗?且不知设计原则就像是写书法一样,楷体就是方正,竖道有垂露等,隶书横有蚕头燕尾等. 这些“秩序”遵循SOLID architecture principles.这组面向对象的设计原则,通过实践总结为 1),SRP(Single Responsibility Principle):单一责任原则: A class should take care of only…

设计原则解读. 设计原则是对设计模式的约束性要求,属于设计中基本的四项特征,不符合此四项特征的设计,不具有生命力. 设计模式也是在此四项设计原则上的具体化实例化衍生物. Martin原文: http://www.cvc.uab.es/shared/teach/a21291/temes/object_oriented_design/materials_adicionals/principles_and_patterns.pdf Architecture and Dependencies 软件最开始…

Inception V3网络(注意,不是module了,而是network,包含多种Inception modules)主要是在V2基础上进行的改进,特点如下: 将滤波器尺寸(Filter Size)较大的卷积分解成若干滤波器尺寸较小的卷积.根据作者在论文中提出的optimization ideas,大卷积总可以被分解成3*3卷积层序列,而且需要的话还可以进一步分解成更小的卷积,如n*1卷积,事实上,这比2*2卷积层更好.对大卷积层进行分解的好处显而易见,既可以加速计算(多余的计算能力可以用来加…
