Google Glass: The future's on your face

Way back in 1945, Vannevar Bush, the director of the US Office of Scientific Research and Development, wrote a remarkable essay titled "As we may think." In it, Bush predicted the rise of the worldwide web. He also wrote that "the camera hound of the future wears on his forehead a lump a little larger than a walnut. It takes pictures 3 millimetres square, later to be projected or enlarged."

Bush's future is here. With the arrival of Google Glass, the camera is even smaller than a walnut.

In a detailed piece in The New York Times, author Clive Thompson looks at the history of wearable computing, beginning with Bush's vision. He talks about the experiment conducted by mathematician Edward Thorp and Claude Shannon , the engineer and cryptographer known as the father of information theory. Thorpe and Shannon created a small device, the size of a cigarette pack, that they used to beat the odds at roulette at Las Vegas casinos. This was the first wearable computer.

Thompson also talks about Thad Starner, first a student, then a professor at MIT. As a student , in 1993, Starner found it difficult to take notes and concentrate on what his professor was saying at the same time. He built a device to help him. It was made of computer parts stored in a backpack. Input was through a one-handed keyboard called the Twiddler. The user interface was an LED display clipped two inches in front of his right eye. He found the device so useful that he has used it for nearly 20 years now. In 1998 Starner met Larry Page and Sergei Brin, the founders of Google. Years later, Brin and Page would hire Starner to help them work on Google Glass.

Thompson also discusses the design process of Google Glass - how it went from a mad scientist's design to its current streamlined structure, with one arm acting as a trackpad, the other arm acting as a speaker that plays music directly against the skull. A future so bright, you gotta wear shades!

Google Maps gets multi-stage directions

LONDON: Google has reportedly updated its Maps app providing users with multi-stage directions, flight reservations, notifications for upcoming events all in maps themselves.

The update lets users search for multiple destinations for varied ways of commuting and they can then add up to ten new locations to the list of locations and rearrange them as per frequency of visits.

According to the Guardian, the public transport directions are however limited to one end point.

The update also lets users see upcoming events: music, sports or play, while planning a trip in that location.

The updated app also lets users signed in with their Google account searching for an airport, hotel or restaurant, for which they have booked for alongside the venue in their location search results, the report added.

PC Versus Workstation: Which Does Your Office Need?

PC Versus Workstation: Which Does Your Office Need?

 

You’d be hard-pressed to do your office work without a computer. It’s a tool that your office must use, deal with, purchase, and maintain. You don’t want to waste money on a piece of equipment you don’t need, but will spending more on a workstation really cost more in the long run? Check out the tips below to help you figure out which setup best suits your office’s needs.

What is the difference between a PC and a workstation?
1. Cost. Most business PCs cost as low as $500 and go as high as $1,000, whereas a workstation can start at $1,500 and go as high as $3,000 for a high-end machine.
2. Performance. A PC has enough power to do most tasks such as email, web surfing, and word processing. But a workstation has more power. It can handle CAD, animation, data analysis, and photorealistic renderings, as well as video and audio creation and editing.
3. Durability. The internal workings of a workstation are held to a higher standard than those of a PC. Each part (motherboard, CPU, RAM, internal drives, video cards, etc.) is built with the understanding that it will be pushed hard all day long. In many cases, workstations are working on projects when all the humans have gone home. They are left to crunch large databases or create animations overnight.
If one option costs more, then you would expect more—that’s the case with a workstation.
Computers typically classified as a workstation have these five features:
  • ECC RAM. Error-correcting code memory makes your system more reliable. It fixes memory errors before they affect your system, preventing crashes and saving you downtime.
  • Multiple Processor Cores. More processor cores mean more processing abilities. However, it won’t guarantee performance boosts. The software you are using has to be programmed to take advantage of it, but it will provide some benefit.
  • RAID (Redundant Array of Independent Disks). RAID uses multiple internal hard drives to store and process your data. There are several different types of RAID systems. Depending on the type of system, you can get multiple drives processing your data, or you can get mirrored drives, meaning that if one drive fails the other will still function.
  • SSD. Solid State Drives work differently than conventional hard-disk drives. There are no moving parts, so there is less chance of a physical failure. They are also faster. The downside is that they are more expensive and have a smaller storage capacity than that of “regular” drives.
  • Optimized GPU. All computers need to output to a screen. Having a higher end GPU (Graphics Processing Unit) means that your CPU will have to do less work processing the screen output. In some cases, the GPU can actually take over some of the load from the CPU, making everything faster. The downside is that high-end GPUs are expensive.
Most of this is obvious: If you spend more, you get more. But is doubling your cost a good idea? Often the answer is yes. If you planned to spend $700 but now spend $1,500, you naturally hope for twice as much. You need to ask yourself the following: How much time does it cost you in downtime and in time spent dealing with issues that come from underperforming computer hardware?
If it saves you 30 minutes a week over the course of three to six years (the average lifespan of an office computer), that adds up to 26 to 52 man-hours. Multiply that with your billing rate, and that is the money you are losing. If your rate is $50 per hour, then 26 hours saved is $1,300. That’s practically the entire cost of the workstation. Also, keep in mind that your employees will be much happier while they work if their equipment is more reliable and functions the way they expect it to. That alone will increase production.
