2月1日消息,亚马逊本周二宣布将在肯塔基州开建其第一个航空货运中心,以应对高速增长的航空货运需求.亚马逊预计,该项目将带来2000个工作岗位. 据悉,该项计划总投入约为15亿美元,亚马逊或可从当地政府获得4000万美元的税收激励.但亚马逊方面尚未透露项目的相关文件审批进度.值得一提的是,全世界最大的物流中转中心UPS世界港以及FedEx最大的包裹分检中心均在肯塔基州境内. 有知情人士表示,亚马逊的这一措施将减少其对UPS和FedEx等传统货运巨头的依赖,未来有望成为他们的直接竞争对手. 去年,亚…

1 代码优化 1 尽量静态化 如果一个方法能被静态,那就声明它为静态的,速度可提高1/4,甚至我测试的时候,这个提高了近三倍. 当然了,这个测试方法需要在十万级以上次执行,效果才明显. 其实静态方法和非静态方法的效率主要区别在内存:静态方法在程序开始时生成内存,实例方法(非静态方法)在程序运行中生成内存,所以静态方法可以直接调用,实例方法要先成生实例再调用,静态速度很快,但是多了会占内存. 任何语言都是对内存和磁盘的操作,至于是否面向对象,只是软件层的问题,底层都是一样的,只是实现方法不同.静态…

今天稍微复杂点的互联网应用,服务端基本都是分布式的,大量的服务支撑起整个系统,服务之间也难免有大量的依赖关系,依赖都是通过网络连接起来. (图片来源:https://github.com/Netflix/Hystrix/wiki) 然而任何一个服务的可用性都不是 100% 的,网络亦是脆弱的.当我依赖的某个服务不可用的时候,我自身是否会被拖死?当网络不稳定的时候,我自身是否会被拖死?这些在单机环境下不太需要考虑的问题,在分布式环境下就不得不考虑了.假设我有5个依赖的服务,他们的可用性都是99.9…

引言 GC 作为CLR的垃圾回收器,让程序员可以把更多的关注度放在业务上而不是垃圾回收(内存回收)上.其实很多语言也有类似的东东, 如Java也有JIT 等等 GC基本概念 垃圾回收机制的算法有好多种,GC为Mark-Sweep算法. GC中分为三代,来优化管理不同生命周期的对象. 大部分的对象在Gen0就死掉了. Gen0 和Gen 1 又叫作ephemeral generations (短命代,个人翻译意见 ) 大于85,000bytes的对象会被直接分配到Large object heap…
