等了好久的desktop主机今天终于到了,UPS Ground,从下订单到收到主机过了整整八天,有点慢,等得我心力交瘁。Google手机nexus one今天也到了(帮同学买的),昨天下的订单,今天就收到了,用了Fedex Overnight,效率真赞。拿到主机后,迫不及待的拆了瞧一瞧,这可是我人生中的第一台desktop,有点兴奋。拿出安装说明书,配上前几天到的Dell显示器,花了点时间把机子装好,启动。启动速度很快,比我的笔记本快好多,台式机内存4G,笔记本的3G,笔记本的主频比台式的高一点,为毛笔记本那么慢,看来随着使用时间的推移操作系统也有老化的问题,kidding。台式机的系统是Vista Home Premium,笔记本的是Vista Ultimate,应该是OS的区别导致不同的启动速度,sigh,功能多的不一定好。打算在台式机上装双系统,Windows和Linux,但硬盘没有分区,折腾了一会,把硬盘分成了四个区,Vista占三个,150G,250G,100G,剩下的75G留给Ubuntu。其他的空间要么莫名消失,要么被整到了不可控的分区里,不过硬盘已经够大,我不是那种喜欢存电视剧or电影的人,五百多G的空间足够我瞎整了。

听Sumeet说过,老板的研究方向正在往CPS转移,CPS是个比较新的领域,注重计算资源与物理资源的紧密结合与协调,个人觉得,比较像Embedded System和Wireless Sensor Network的结合,主要用于一些智能系统上,如机器人,智能导航等。以下是Wikipedia对CPS的描述,比我说的权威多了。
A cyber-physical system (CPS) is a system featuring a tight combination of, and coordination between, the system’s computational and physical elements. Today, a pre-cursor generation of cyber-physical systems can be found in areas as diverse as aerospace, automotive, chemical processes, civil infrastructure, energy, healthcare, manufacturing, transportation, entertainment, and consumer appliances. This generation is often referred to as embedded systems. In embedded systems the emphasis tends to be more on the computational elements, and less on an intense link between the computational and physical elements.
