客厅PC之平台抉择

正上期我们介绍了智能客厅重要的组成部分——客厅PC的组装心得和部分技巧。有读者反馈问,既然内置GPU就能够满足视频播放的需要,那么我们应该选择Intel的核芯显卡还是AMD的APU的独显核心呢?目标——极端性价比我们只需要一台能够流畅读写局域网/互联网内容,能够流畅播放主流视频文件的平台即可,这时体积小巧而性能均衡的一台一体电脑就能够很好地解决客厅PC的所有需求了。当然在能够满足这个目的基础上,整个平台所需的成本越低越好。     

悬在国产网游头上的达摩克利斯之剑

虽然关于网络游戏的负面报道层出不穷,可是还是有无数玩家投身其中,让网络游戏运营商笑逐颜开。为了拉拢用户,很多运营商都在游戏中设置了诸多非常有“中国特色”的功能。表面上看这是方便了玩家,降低了游戏的上手难度,但深究起来,这些设定也很有可能是悬在国产网游头上的达摩克利斯之剑。     

A change management framework for macroergonomic field research

With the proliferation of macroergonomic field research, it is time to carefully examine how such research should be managed and implemented. We argue that the importance of attending to high-quality implementation of field research is equal to that of methodological rigor. One way to systematically manage the implementation process is to adopt a change management framework, wherein the research project is conceptualized as an instance of organization-level change. Consequently, principles for successful organization-level change from the literature on change management can be used to guide successful field research implementation. This paper briefly reviews that literature, deriving 30 principles of successful change management, covering topics such as political awareness, assembling the change team, generating buy-in, and management support. For each principle, corresponding suggestions for macroergonomic field research practice are presented. We urge other researchers to further develop and adopt frameworks that guide the implementation of field research.     

一个iPhone新人的烦恼——iTunes你就是个渣

写下这个标题时,我觉得我有挨板砖的危险。因为国内的苹果Fans太多了,谁也对苹果的东西稍有不敬,立刻就会被轰杀至渣。不过,作为一个苹果iPhone手机的新玩家,我对其配套软件,也就是苹果最热门的播放及同步管理软件iTunes,确实有一些不满……     

怎样才能突破封锁、隐身BT载？

为了有效控制BT下载流量,网管一般都会用软件屏蔽BT客户端的端口（默认6881-6889）和常用BT服务器,这样你在单位局域网内就不能使用P2P工具进行BT下载了。有些场所局域网内允许BT下载,但速度却非常慢,如果想突破这类限制,应该怎么办呢？如果在BT下载时又不想暴露自己的IP,希望能进行隐身BT下载,又该怎么办呢？     

口述下载那些事儿

不管下载软件背后有多少破事儿,要追看美剧,它们还仍然是我们的第一选择. 和大家一样,我也是美剧迷,每次出新剧,也和大家一样激动万分地等待,第一时间挂夜下载.不过,和大家不一样的是,你们用别人写的软件下载,我用自己写的软件下载.     

Metal/dielectric transmission interference filters with low reflectance. 2. Experimental results

The successful fabrication of metal/dielectric multilayer filters requires not only accurate control of the individual layer thicknesses, but also a good knowledge of the optical constants of the materials used in the filters. In the case of metal films, it is also essential to know whether any transition layers are formed at the interfaces and, if so, how their thicknesses and optical constants depend on the deposition conditions. An automatic, real-time process control, magnetron sputtering deposition system was modified to permit the manufacture of metal/dielectric filters using optical monitoring techniques. To illustrate the performance of this system, two bandpass filters, a short-wavelength pass filter, and a neutral density filter were produced, all having a low reflectance for light incident on one side. The metal layers used in these filters consisted of either Ni or Ag. TheAg films could be protected from the O(2) plasma using thin Ni or Si films. Good agreement was obtained between the calculated and measured spectral transmittance and reflectance curves.     

Toward a theoretical approach to medical error reporting system research and design

The release of the Institute of Medicine (Kohn et al., 2000) report "To Err is Human", brought attention to the problem of medical errors, which led to a concerted effort to study and design medical error reporting systems for the purpose of capturing and analyzing error data so that safety interventions could be designed. However, to make real gains in the efficacy of medical error or event reporting systems, it is necessary to begin developing a theory of reporting systems adoption and use and to understand how existing theories may play a role in explaining adoption and use. This paper presents the results of a 9-month study exploring the barriers and facilitators for the design of a statewide medical error reporting system and discusses how several existing theories of technology acceptance, adoption and implementation fit with many of the results. In addition we present an integrated theoretical model of medical error reporting system design and implementation.     

让PPC同时遥控四台机器

家庭数字多媒体中心这个概念随着Intel和微软的不遗余力地推广，已经越来越深入人心，目前国内的品牌有联想的悦灵通以及微软的Windows Media Center。简单来说，就是借助软件或硬件的帮助，通过无线连接实现在电视机或任意一台电脑上共享其他电脑上的音频和视频资料：当然，要实现这个，一个遥控器是少不了的。电视还好说，而电脑上，你就必须配一个红外线适配器才可以实现遥控功能。那么，是否能够利用现成的东西呢？比如无线或蓝牙？Rudeo MCE Remote就是这样一款软件，它能将PDA转换成一个功能强大的遥控器。
