The Great Firewall of China
Two steps forward, one step back...
At least China's citizens now have access to the Internet, just not the entire Internet. Any website, message, or packet that contain as little as one word from a list of black-listed terms (compiled by the PRC's Ministry of Public Security) will not be fully processed. Instead, the packets are reset and not allowed to continue to the next router. The user is usually left with a "broken link" message. This is cleverly dubbed the Great Firewall of China, but how fool-proof is it? Read Jacqui Cheng's article "Great Firewall of China more like chain-link fence", which discusses the new research from UC Davis and University of New Mexico CS Departments.
You can't help but root for the Chinese citizens. It's the classic Man vs. Establishment conflict but with a digital twist. The Internet is truly a force to be reckoned with. Not even a communist government can cage the global beast that is the Internet.

Nuking Ramen Noodles in the Digital Age
Key features of Microsoft's Kitchen of the Future:
- Family Information console, replacing the cluttered fridge door, synchronizes with personal devices to display schedules, contact lists, memo's, chores list, weather forecasts, e-mail alerts, etc.
- Hands Free telephoning with caller ID and voice-dialing/answering. Sync'ed with contact lists.
- Phone sends directions, recipes, and other information to the caller, all by voice commands.
- Microwave's UPC scanner collects "cooking time" information from each food product (Ramen noodles made easy...easier) and also updates its own database after every use.
- Microwave alerts the user, wherever in the house, that microwaving is done.
- Microwave updates the user's "inventory" (a pantry or cupboard for the layperson) after every consumption.
- Kitchen computer constructs feesible recipes based on ingredient availability.
...Very Jetson's-esque.
