Summer is still three months away, but here in Northern California, with bright sunshine outside (and windows to keep the chilly wind out), it already feels like it's just around the corner.

That's also because I've already started the planning for Road Trip 2013, my eighth-annual journey to highlight some of the best destinations around for technology, military, architecture, science, nature, and so on.

For six of the past seven years, CNET Road Trip has taken me all around the roads of the United States, giving me the opportunity to visit the Pacific Northwest, the Southwest, the … Read more

Six states have officially made it illegal for employers to ask their workers for passwords to their social media accounts. As of 2013, California and Illinois have joined the ranks of Michigan, New Jersey, Maryland, and Delaware in passing state laws against the practice, according to Wired.

With Congress not being able to come to agreement on the Password Protection Act of 2012, individual states have taken the law into their own hands. Both California and Illinois agreed on password protection laws in 2012, but the laws didn't go into effect until yesterday.

The laws are designed to prohibit … Read more

With all the James Bond theme song-playing and tower-building quadrocopters these days, it's a little hard to get excited about new personal-size automated aerial projects. But how can you not get worked up by a bird robot that can cross a room and land gracefully on someone's hand?

Aerospace engineering researchers at the University of Illinois at Urbana-Champaign have "duplicated the control functions that allow birds to successfully perform a soft landing--in this case, perching on a human hand."

The above video's a bit scientific for the average layman (read: me) but suffice it to say, the researchers -- Soon Jo Chung, Aditya Paranjape, and Joseph Kim -- have created a micro-aerial vehicle (MAV) that can fly nimbly across a room and then pull up at just the right moment for a soft landing at a specific place, or on someone's hand. … Read more

You might wonder where Mr. Whiskerpuffs goes after he's let out the back door. You may imagine that he lounges around in the sun and swats at butterflies in the neighbor's yard. He may actually be holding down a 5-acre territory.

A master's thesis study, led by former University of Illinois at Urbana-Champaign graduate student Jeff Horn, tracked 42 feral and pet cats as they collectively roamed more than 6,000 acres over the course of two years.

Radio telemetry and movement sensors gave the researchers a pile of interesting data. The largest range for a single cat belonged to a feral male that claimed 1,351 acres of room to roam. Pet cats tended to keep things much closer to home.

One unsurprising (at least to cat owners) finding was that the pet cats were lazy little fluffballs. They were asleep or in a low-activity mode for 97 percent of the time. The feral cats didn't have such cushy situations. They were in high activity mode for 14 percent of the time. It takes extra effort to make a living when you don't have a bowl of Friskies waiting at home.… Read more

CARBONDALE, Ill.--When you see a geodesic dome, you know exactly what it is. You don't have to wonder if it's Georgian, Victorian, or neomodern. It's a dome. All those geodesic dome homes trace their lineage back to a quiet corner of Forest and Cherry in Carbondale, Ill.

R. Buckminster Fuller was the mind behind the dome home. He built what's known locally as the "Bucky Dome" just over 50 years ago, out of panels of plywood. He meant for it to be cheap and easy to put together. The original assembly took just seven hours. Since the 1960s, domes have reproduced and spread out around the country in a wide migration of Fuller's ideas. It's no wonder many people think of him as the grandfather of the sustainability movement.

An effort to restore the dome has been given new life with the recent award of a Save America's Treasures matching grant to the tune of $125,000. "He envisioned the dome as a house. It was the first dome home. It's the only one he ever lived in," says Janet Donoghue, development director of the nonprofit RBF Dome NFP, which is looking to resuscitate the worn structure.

The group has its work cut out for it. "When it was built, he said the material he needed to make it waterproof wasn't invented yet," says Donoghue. The Bucky Dome is in rough shape. Sad brown shingles cling helplessly to the outside, mold has taken hold on the inside, and many of the plywood triangles are water-damaged.

A much more modern geodesic dome in the form of metal piping and tarps covers the entire outside in an attempt to protect Bucky's former residence.… Read more

CARBONDALE, Ill.--It has been many years since I have worn armor, grabbed a battle axe, stormed a castle, and watched my hit points drain away. My childhood came rushing back as I stood just inside the gates of the Jeremy "Boo" Rochman Memorial Park in Carbondale, Ill. I strapped on my breast plate, loosed my broadsword from its hilt, and let out a mighty battle cry... in my mind.

I'm on a detour from the Geek's Guide to Route 66. I veered off the path somewhere around St. Louis and wandered into the welcome arms of Carbondale, where weathered farmers surreptitiously check their iPhones at the local bar. That's my kind of town.

This park on the outskirts along Giant City Road is one of those places you hear called a best-kept secret. It wasn't secret to the dozen kids climbing over the head of a dragon and romping through the castle walls. Wizards battle on green grass, Pegasus rears up from the brush, and gargoyles guard the ramparts. This is Dungeons & Dragons come to life.

There is a sad story behind the magical kingdom, though. Local investment mogul Barrett Rochman built the park as a memorial to his teenage son. Jeremy "Boo" Rochman, an avid Dungeons & Dragons fan, died more than a decade ago in a car accident nearby. According to an article in the Southern Illinoisan, some of the statues in the park are based on painted figures found among Boo's possessions.… Read more

Comcast customers in Illinois and three other nearby states lost their Internet access last night, apparently due to the same problem that took down service for East Coast customers just a week ago.

Reports first began showing up on Twitter, with Comcast customers in several Midwest states tweeting that their connections were down. Comcast's own Twitter account, Comcastcares, later confirmed that the outage was affecting people in Minnesota, Illinois, and Michigan and seemed to be Domain Name System (DNS) related. The company also said at the time that it was working on a fix.

More specifically, the outage hit … Read more

The director of the National Center for Supercomputing Applications has seen the future of supercomputing and it can be summed up in three letters: GPU.

Thom Dunning, who directs the NCSA and the Institute for Advanced Computing Applications and Technologies at the famed supercomputing facilities on the campus of University of Illinois at Urbana-Champaign, says high-performance computing will begin to move toward graphics processing units or GPUs. Not coincidentally, this is exactly what China has done to achieve the world's fastest speeds with its "Tianhe-1A" supercomputer. That computer combines about 7,000 Nvidia GPUs with 14,000 Intel CPUs: the only hybrid CPU-GPU system in the world of that scale.

"What we're really seeing in the efforts in China as well as the ones we have in the U.S. is that GPUs are what the future will look like," said Dunning in a phone interview Thursday. "What we're seeing is the beginning of something that's going to be happening all over the world."

NCSA already has a small CPU-GPU hybrid system. "It's something we have been working on for a number of years. We have a CPU-GPU cluster for the NCSA academic community. Made up of Intel CPUs and Nvidia GPUs. A 50 teraflop machine," he said. (Note that Oak Ridge National Laboratories is also installing a hybrid system now.)

But it's not going to be a snap to tap into the processing potential of GPUs. "Programming these machines to do [GPU] calculations is still a very substantial effort. There will be some applications that will be rewritten to use GPUs [but] a lot of times it will be only part of an application that will use it so you won't get nearly the power and computing advantage of running it all on the GPU," he said.

The catalyst to move programmers en masse toward GPUs will be when chips appear that combine both high-performance CPU and high-level GPU functions on the same piece of silicon, Dunning said. "If they start to solve some of these other problems like… Read more

There is a view that removing all 15-year-old boys from this earth would not only help global warming but also our cultural horizon.

Supporters of this view will then be heartened to hear the story reported by the Chicago Tribune of a 15-year-old boy who suffered a serious trauma. His parents took away his Xbox.

The boy, a resident of Buffalo Grove, Ill., which sounds like the sort of place where discipline is imparted along traditional lines, decided to express his feelings and exert his identity. He called 911 in order to ask the police whether his parents were, indeed, … Read more
