I'm currently renovating my house in Belgium.

I drew all my plans in metric units and in the building materials shop all sizes are metric as well. (you would greatly confuse them if you order a 50 pounds of cement or a metal bar of 3 yards).
One noticeable exception is the width of sanitary pipes; these are measured in inches and quarter inches. (which greatly confuses me)

I can't speak for the situation in Iran, but here in Beijing it's virtually impossible to get on the Tor network.
All bridges that are published by the Tor team are all unreachable (including those published on social networks). The only way to get on the Tor network is to have a friend set up a private bridge.

If China manages to block Tor, Iran may be able to do the same (now or in the near future)

78 miles per gallon is about 3 liter for 100 km.

198 miles = 319 kilometers

Well, from Beijing:

surfing to http://google.cn/ will show you something that looks like google's homepage, only, it's just an image of the homepage. Clicking on it will lead you to google.com.hk. (the version in simplified Chinese characters)
What changed a couple of weeks back is that they do not redirect you automatically, you just end up on this landing page.

Interesting to note: passing a query directly to google.cn (from the search box in firefox), will just execute the query on google.com.hk

Purely theoretical:

- User boots live-cd
- Some malware gets executed and stays in RAM (by user interaction or not)
- Malware reflashes the EEPROM holding the BIOS with some malicious code
- On next boot BIOS will store some malicious code in memory and does something very clever that makes the OS on the liveCD execute that code

It would be a very targeted attack, but not entirely impossible

For instance, the good old light bulb. This one is going for over a hundred years and still counting.

I wonder how long it will takes before LED bulbs beat that (yes, at least a 108 years)

You were not the first one. "Dark Room" a PC game making use of the Wii controller. And yes, it uses the Wiimote in a very adult-y way.
