通过Ubuntu软件中心，分享你喜欢的软件

Ubuntu软件中心最近有一系列的变化，其中比较有意思的是给软件评价和打分，并通将其分享到twitter和facebook这类SNS上去。
一 打开软件中心，找到你要评价或者打分的软件。

二 点击更多信息

三 点击上图有下方的 "write your own review" 会弹出如下窗口。

如果您还没有Ubuntu单点登陆帐号的话，或者第一次使用的话，都会弹出Ubuntu单点登陆注册/认证对话框，注册和认证都很简单。
如果需要将你的评价分享到twitter或者facebook等SNS网站，你需要在gwibber里设定好相应的帐号，然后在上图的对话框里勾选 "Also post this review to" 。

欢度春节

My experience with openstack

Spent some time over the last week on openstack, Its written in Python, so its very easy for troubleshooting during installation or for daily maintenance. I have deployed eucalyptus for clients demo purpose, its really bad from what I can say. The whole java stack is too complicated. Back to openstack, there has something interesting through my experience.

1 Its written in Python, so its a big advantage over eucalyptus to me.

2 Easy to deploy, you can even install it inside a vm, I installed it with virtualbox.

3 Supports sorts of virtualization technologies, like kvm, qemu, xen, hyperV, even UML being supported.

4 Totally modulized architecture, you can easily add new function.

5 Fully open source, but not eucalyptus. :)
