开源硬件的定义

作者:comet 日期:2010-07-16

BoingBoing covers the launch of the "Open Source Hardware Definition" and the announcement of the first Open Hardware Summit. "Open Source Hardware (OSHW) is a term for tangible artifacts -- machines, devices, or other physical things -- whose design has been released to the public in such a way that anyone can make, modify, distribute, and use those things. This definition is intended to help provide guidelines for the development and evaluation of licenses for Open Source Hardware."

vmware中linux虚拟机的时间同步

作者:comet 日期:2010-07-05

使用vmware server创建的虚拟机会有时间不同步的情况，如果是windows的虚拟系统，可以通过安装vmware tools后在控制面板设置好便可以定时同步。如果是linux的虚拟系统，通过编辑vmx文件，添加或修改对应的选项：

tools.syncTime = TRUE
time.synchronize.continue = TRUE
time.synchronize.restore = TRUE
time.synchronize.resume.disk = TRUE
time.synchronize.shrink = TRUE
time.synchronize.tools.startup = TRUE

解释如下：

Option	Effect
tools.syncTime	If set to TRUE, the clock syncs periodically.
time.synchronize.continue	If set to TRUE, the clock syncs after taking a snapshot.
time.synchronize.restore	If set to TRUE, the clock syncs after reverting to a snapshot.
time.synchronize.resume.disk	If set to TRUE, the clock syncs after resuming from suspend and after migrating to a new host using the VMware VMotion feature.
time.synchronize.shrink	If set to TRUE, the clock syncs after defragmenting a virtual disk.
time.synchronize.tools.startup	If set to TRUE, the clock syncs when the tools daemon starts up, normally while the guest operating system is booting.
