Cisco offered a comparison that suggests how big mobile has become: the traffic on mobile data networks in 2012 885 petabytes was nearly 12 times greater than total Internet traffic around the world in 2000, back when the web was taking off.

Firstly, this scheme implements a multi-scale morphological open-close filter, to get the low-frequency smooth image for the source image.

这种方法首先对源图像进行多尺度形态学开闭滤波，得到源图像的低频平滑图像；

However, in general, the existence of proprietary software is fine by me, and I even buy some closed-source software if it does something I want done well enough to be worth the money.

不过，总的来说，专有软件的存在，我是不介意的，而且，如果闭源软件物有所值，我甚至还会购买。

Actually, it'd probably work for closed-source projects as well; the only difference in that case is that the mailing list should, of course, not be visible to the public.

实际上，对闭源项目也是可行的；唯一的差别是邮件列表要对公众不可见。

The reality is that many closed-source vendors are not particularly evil or malicious, are not concealing rootkits, and are just trying to make a living in a way that they know how to make work.

事实是很多闭源供应商并不那么地邪恶或恶毒，也并不故意要隐藏rootkit，他们只不过是在试图借助自己的所知所能谋生而已。
