Light Bulb with Wi-Fi

Isn't it cool to have an affordable internet connection from a light bulb? I found this post on Technology Blog's Facebook page:

Chinese Scientists Invent Lightbulbs That Emit Wi-Fi

A group of Chinese scientists at Shanghai's Fudan University have a bright idea: A lightbulb that produces its own Wi-Fi signal. According to Xinhua, the technology is called Li-Fi, and the prototype actually works better than the average connection in China.

As many as four computers placed near a Li-Fi bulb can connect to the net, using light frequencies rather than the usual radio waves. The bulb is embedded with a microchip that produces a signal, yielding rates as fast as 150 mbps—far faster than typical connection speeds in China.

One of the perks of Li-Fi is that it's affordable. Have a lightbulb and a Li-Fi kit? Boom—you have internet. Next month, researchers are showing off 10 sample kits at a trade show in China, and the country is moving in a direction that could make Li-Fi a practical and commercially viable asset—especially since, as Xinhua reports, Chinese people are quickly replacing old fashioned incandescent bulbs with LEDs.

Of course, there are still a few technical details—mostly dealing with microchip design and manufacturing—that would need to fall into place before Li-Fi becomes ubiquitous. 

So for now, Li-Fi remains an experiment with a bright future.

How to Clean Your Computer

You might be having some problems cleaning your desktop and laptop. If you want to clean your PC just like a PC Cleaner would, here are the things you can do:

Clear your browser history. You can also set your browser to automatically clear its history when you close it. - I prefer to clear my browsing history before I turn my pc off.

Run the Disk Cleanup tool included with Windows. It will free up space on your hard drive, but it will also delete old temporary files and other useless things. Just click the Windows key, type Disk Cleanup, and press Enter to launch it. You can schedule a Disk Cleanup to clean your computer automatically.

Run the Disk Defragmenter included with Windows. If you use a solid-state drive, this isn't necessary.

Don't bother with a registry cleaner. Use the Free CCleaner instead, which has the best tested registry cleaner. It will also delete temporary files for other programs.  - Whenever I am about to turn the pc off, I clear my browsing history first and proceed to CCleaner, before I turn the pc off.

Share these simple steps to your friends and family too.

The New $249 Samsung Chromebook

Techo locos, introducing the new Chromebook. The $249 laptop from Google. For everyone.

"The new Chromebook is a great computer at any price, but it’s an incredible computer at $249. It’s one of the lightest laptops on the market. You can easily carry it around all day—it’s 2.5 pounds, a mere 0.8 inches thick, with more than 6 hours of battery life for the typical user. And with 100 GB of free storage on Google Drive*, you can get to all of your stuff anytime, anywhere.

Even with its compact design, it’s packed with performance—it boots up in less than 10 seconds and resumes instantly. High-resolution videos (in 1080p) are beautiful to watch and when using the touchpad, you’ll notice smooth scrolling due to a hardware-accelerated user interface. And as you‘d expect from a Chromebook, it’s easy to share with others. Everyone—mom, dad, grandparents, tech lovers, tech haters—can have separate accounts where all of their stuff is kept safe. Finally, if you’re an active Google user of products like Gmail, Drive, Search, Maps, YouTube, Play or Google+ Hangouts, everything just works seamlessly."
