While I think to something more interesting to write, I'll deal with something which is just technically astonishing. But it's also an example of the infrastructure difference that prompted me to move here. So one could probably invent a philosophical meaning for this post. Like "the Author is trying to suppress his homesickness with the reasons for which he moved to a place with better infrastructure". Well, I didn't move just for what is discussed below, but hey, it's a nice bonus.

OK, in practice: here's what I got today on my console:

$ ping www.google.com

rtt min/avg/max/mdev = 3.290/3.486/3.707/0.170 ms

Noticed something? Like the fact that it's contacting in 3 milliseconds a Google server in the US (click the link if you don't believe me)?
