Elon Musk: In 20 years, most cars will be electric

By By David Daw

In 20 years, a majority of new cars will be electric and the world's single largest source of energy will be solar power, Tesla Motors and SpaceX founder Elon Musk said today.

Speaking at the TechCrunch Disrupt conference here, the 40-year-old billionaire co-founder of PayPal shared his vision of the future, and also gave the room full of would-be entrepreneurs some sobering advice about what they should expect when trying to get companies off the ground.

"Expect it to be difficult," Musk said. "A friend phrased it well: 'Starting a company is like eating glass and staring into the abyss of death.'"

Those are no doubt harrowing words, but in speaking them in the closing talk at Disrupt it would seem Musk wasn't trying to discourage those in the room from seeking their own innovations. Rather, he wanted entrepreneurs to have a decent sense of what's in store.

Musk has in recent years tackled two major efforts: making exciting electric cars, and building a profitable private space industry. And though his perspective may be colored by his own experiences, he said he feels the two biggest problems humankind must solve to have a bright future are clear.

Taking Dreamy, Misty Ocean Photos at the Beach

By: Dave Johnson     Sep 12, 2011

The beach is one of those idyllic, picturesque settings that begs to have its photo taken. No matter what kind of camera you have or how you take pictures at the beach, you almost can't go wrong when you're standing on the sand and shooting the ocean. But while most people tend to take pictures midday to capture a gorgeous blue sky with fluffy white clouds above the sand and sea, I'd like to suggest another way to shoot the ocean: Use a slow shutter speed to turn the water into a moody, foggy blur. This isn't the first time I've explained how to capture the essence of water motion with a slow shutter speed (check out "How to Photograph Waterfalls and Moving Water"), but this week let's look at how to apply this technique at the beach.

Cheating With Shutter Speed

People often see a photo like this one and try to guess how it was done. "Was it really misty there?" people ask. "Was there a fog rising off the ocean in the early morning?" And the answer, of course, is no and no. There's no fog, and the scene didn't look like this in real life. Instead, what you see is the effect you get when you slow down the shutter speed and capture a lot of wave movement in the same exposure.

NETWORKING

LAN 101: Networking Basics

By Bestofmedia Team     September 15, 2011

A network is a group of two or more computers that intelligently share hardware or software devices with each other. A network can be as small and simple as two computers that share a printer or as complex as the world's largest network: the Internet.

Intelligently sharing means that each computer that shares resources with another computer or computers maintains control of that resource. Thus, a USB switchbox for sharing a single printer between two or more computers doesn't qualify as a network device; because the switchbox, not the computers, handles the print jobs, neither computer knows when the other one needs to print, and print jobs can potentially interfere with each other.

A shared printer, on the other hand, can be controlled remotely and can store print jobs from different computers on the print server's hard disk. Users can change the sequence of print jobs, hold them, or cancel them. And, sharing of the device can be controlled through passwords, further differentiating it from a switchbox.

New HP TouchPads to Take Weeks, But They're Still Cheap

By Mark Hachman   September 7, 2011

Still waiting for the discounted HP TouchPad? You'll have to wait a little longer. No, wait: a lot longer.

That's because the company has begun emailing potential customers that the new batch of TouchPads will take six to eight weeks to fulfill, according to reports. PreCentral, who obviously was interested in obtaining a new, cheap tablet, as was PCMag.com's Chloe Albanesius reported that there's some good news, though: the TouchPads will be sold at their "discounted price," or $99 for the 16-GB version and $149 for the 32-GB model.

Last week, HP confirmed that it would manufacture one last batch of HP Touchpads, most likely to satisfy component suppliers. In its email, HP described the interest as "overwhelming". The company did not confirm the shipping delay on its blog or on its official Twitter account, however.
