LA JOLLA, Calif.--Cottages shouldn't stick out way over the edge of buildings, but when they've been picked up by mysterious forces and dropped out of the sky, that's exactly what can happen.

Welcome to Korean artist Do Ho Suh's "Fallen Star," a small, New England-style house that was unveiled in June atop -- and well out beyond the roof of -- the Jacobs Engineering School building at the University of California at San Diego here.

I've come to explore "Fallen Star" as part of Road Trip 2012, and though I'… Read more

They say you can find inspiration anywhere, so why not a crab dinner?

Inspired by our crustacean friends, researchers in Singapore have created a mini robot that can be used to remove early-stage stomach cancer in a far less invasive way than other procedures. The robot has the ability to crawl down a patient's throat and features a pincer and hook that can remove cancerous tissue.

The idea first came up in 2004 when Lawrence Ho, an enterologist at Singapore's National University Hospital, and Louis Phee, an associate professor at Nanyang Technological Institute's School of Mechanical and Aerospace Engineering, had dinner with Hong Kong surgeon Sydney Chung, who is well-known for his fight against SARS.

While dining on Singapore's signature chili crab dish, Chung suggested the two use the crab as a prototype, making note of the strength of a crab's pincers and its ability to pick up sand. … Read more

In the middle of the desert between Israel and Palestine, Ghost's high-tech Virtual Computer is set to launch Tuesday. After three years of work, Ghost finished the development of its Web-based operating system that uses "cloud computing" to let users access their desktop and data from any computer worldwide.

Ghost, short for Global Hosted Operating System, was founded in 2006 by Zvi Schreiber, whose goal was to create the Virtual Computer that works with third-party Web applications like Google Docs, Zoho, and Flickr and joins them together into one online service and can be accessed from any … Read more

HO CHI MINH CITY, Vietnam--Last December, I visited Ho Chi Minh City and discovered that while Wi-Fi was ubiquitous and the Internet was fast, it was incredibly hard to get across town.

Seven months later, the traffic here is still terrible. This time, however, I found that if you are in the right place, dealing with traffic isn't necessary at all.

The right place is District 1. Other than being the center of tourism with lots of hotels, famous landmarks, restaurants, and bars, D1 is also the site where you can get pretty much anything you need, especially when it comes to technology and digital entertainment. And it's all within a short walking distance.

I actually heard about this area during my last trip here. Jasper Waale, owner of Skeye, a GPS- and GSM-based tracking company operating in Vietnam and Laos--and an avid listener of the Inside CNET Labs podcast--insisted I check it out. I took a rain check till now.

We met at Cafe Centro, a trendy yet casual coffeehouse located in the middle of D1's most bustling section. According to Jasper, this is a popular place for ex-pats to hang out for both fun and business. It offers reasonably priced refreshments and, of course, free Wi-Fi.

(By the way, there are lots of cafes in Ho Chi Minh City, and pretty much all of them offer free Wi-Fi. My other favorite is Cafe Da on Alexandre De Rhodes Street. Also in D1: the best ice milk coffee and smoothies I've ever had. If you go there, make sure you try the "Dong Tim" fruit shake. It's so good, it has my name on it!)

"You'll find me at Centro at least a couple of times a week," Jasper said. Then, in a slightly show-offy manner, he pulled out his brand-new-looking Nikon D300 camera.

"I just got a good deal on this one. I traded in my D80 and got about 80 percent of new value to put toward this new one. You'll have to come see this place," he said.

I was intrigued, partially because next to his D300, my 4-year-old D80 looked somewhat pathetic. I've considered upgrading my camera for a while, but anticipating the whole hassle of selling my D80 on eBay or Craigslist has stopped me.

He then took me to Thuong Xa Tax, a mini shopping mall that's just a five-minute walk from the cafe. "Mini" here, by the way, is according to American standards; this is actually one of the bigger trading centers here in Vietnam, and it is indeed very large.

As in most shopping malls here, you can find pretty much everything, but we walked straight to the Vinh Hung Camera shop. The owner, Hung, a friendly 40-something man, greeted Jasper like an old friend. He then took a quick look at my D80 and said, "I'll give you $600 for this one, body and lens."… Read more

SAN DIEGO--Why carry a computer laden down with data and applications with you everywhere when you could access all that information from any browser?

That's the proposition behind an Israeli company known as G.ho.st, which presented at DemoFall here Monday afternoon.

Already, the company, whose name is also their URL, has a browser-based version that allows anyone to access all this data from anywhere. The idea is that by doing it this way instead of through traditional virtual computer software, which requires a lot of configuration, you can access your data from any computer.

Now, G.ho.… Read more

Turns out, he's working with a company called Crowd Fusion, a new "Web publishing … Read more

CARLSBAD, Calif.--In the field of start-ups looking to replicate the computer operating system on the Web, Ghost is just one of many.

Like others, it sees an opportunity to not just re-create Windows on the Web, but perhaps to even replace the traditional operating system. I see some interesting notions, but a lot of challenges in these models.

But what struck me most about the company is its unique workforce. Ghost has a few workers in Israel, while most of the company is located in the West Bank town of Ramallah. The idea is to show the world as … Read more

Microsoft's duo didn't do a great job of capitalizing on that position. Rather, they left a lot of room for other companies to excite the audience with newer ideas. Two companies here are taking on that charge.
