New protection at the pump?

 I spent some time in eastern Pa. recently and noticed several times there that when I inserted my credit card at the pump for gasoline, I was asked to enter the ZIP code of the card's billing address..

This is new and I assume it is a way to detect stolen credit cards. Maybe the thinking is if someone is using a gas credit card away from home, it could be a purloined card. I don't know if pumps in my home ZIP code also ask.

But whatever, it is s small price to pay if it inceases security. Anyone else notice this?

A sad day

Although I only knew Randy Pausch by meeting him briefly and attending his class show at the end of the semester at CMU, his natural curiosity, love of life and love of his work radiated from him. His greatest gift was that he could communicate those qualities through his teaching and writing. He will be missed by many.

Trouble in Apple-land

 It seems that Apple has been having a rough time with the launch of its new MobileMe service, meant to replace the old .Mac service.

Had any other company had this kind of launch, I am betting the howl would have been louder. I have always maintained that Apple gets treated with kid gloves by some.

Here is the New York Times' David Pogue's report on the problems.

Tinkering with ones and zeros

I've always been interested in electronics but never really progressed beyond the gadget store 100-in-1 experimenter kit level.  In fact, the last little experiment I tried as a kid nearly set fire to my workbench.  It was then that I realized that computers were easier - in general, they were already assembled and typically weren't the cause of too many house fires.

So when I caught wind of the concept of physical computing (computers that an sense and respond to the outside world), I thought I'd give it another try.

One really inexpensive way to get into the hobby is the Arduino prototyping platform.  It's a small microcontroller board that allows for programming code to be uploaded into its microprocessor and can be powered by USB, batteries or even alternative sources like solar power.  There are a lot of add on boards (called Shields) that you can purchase and assemble to try your hand at more advanced concepts like GPS logging, sound generation and controlling servos and motors.  Some of the more interesting work being done with it can be found on the official Arduino web site.

But for the moment, I'm only fooling around with the thing, getting my head wrapped around the concepts of transistors and diodes again.  About the only thing I'm able to do with it right now is to get an RGB LED to cycle through all of its colors. 

If you're tinkering with Arduino, I'd love to hear from you.

 

Some trouble with new iPod software

So TechMan finally got around to installing the new iPod 2.0 software on his iPod Touch and it wasn't flawless.

First I downloaded the the new iTunes software, which went fine. Then a few days later I tried to install the new version of software for my iPod. Every time I hooked up the iPod to my laptop, iTunes would freeze up.

After this happened a few times, I thought maybe the problem was that I did the process in two steps a few days apart. So I uninstalled and reinstalled iTunes with the idea that the new iTunes would already have the updated software (you can do this without losing content). This seemed to do the trick.

This could have been just particular to me, and I mention it only in case someone else has the same experience. Everything seems to work fine now, I was even able to donwload an application from the App Store.

If an HDTV is in your future, here's a reason to wait a while

A few of the top-tier flat panel TV manufacturers are announcing a further round of price cuts that might shave off as much as $400 from that TV you've had your eye on.  Apparently they've already done this at least once in the last year; good news for those of us who are still using square-faced glass-screened behemoths from the early '90s.

The TV I'm dreaming of (Samsung's 46-inch LN46A650) looks to be about $440 cheaper in the coming days.  Still a bit stratospheric for my tastes but it's an improvement.

Of course, the downside to all of this is that companies love to drop prices on their current lines just before they announce the new technology.

TechMan: Physicist's ideas catch the wide world in a web

 

Welcome to another episode of TechMan's Giants of Technology: Important People You Probably Never Heard Of.

Today's subject is Tim Berners-Lee, inventor of the World Wide Web.Tim Berners-Lee

If there were geek trading cards, he would be one of the most valuable.

In 1989, Mr. Berners-Lee, a physics graduate of The Queen's College, Oxford, where he played table tennis, was working as a physicist at the world-renowned CERN.

CERN, in the suburbs of Geneva, Switzerland, is the world's largest particle physics laboratory and was the largest European node on the youthful Internet.

In a previous stint at CERN in 1980, he had come up with the idea of linking CERN researchers' information using hypertext, an early form of what we now call a "link" on a Web page. It allowed you to go from one place in a document to another or even to a spot in another document. He called his little hack Enquire, inspired by "Enquire Within Upon Everything," a Victorian encyclopedia he remembered from childhood.

During his second CERN term, Mr. Berners-Lee got the idea of combining Enquire with the Internet.

"I just had to take the hypertext idea and connect it to the Transmission Control Protocol and domain name system ideas (two of the building blocks of the Internet) and -- ta-da! -- the World Wide Web," he said.

Ta-da indeed.

It wasn't quite so simple.

First he had to write an easy-to-learn coding system -- HTML (HyperText Mark-up Language) -- that allowed a Web page to be "written." Then he had to come up with a way to find each Web page, called a URL (Universal Resource Locator). And then he had to devise a set of rules, called HTTP (HyperText Transfer Protocol), that permitted Web pages to be linked together on computers across the Internet.

And if that weren't enough, he wrote the first World Wide Web server and a what-you-see-is-what-you-get browser, which ran in the NEXTSTEP operating system, a product of the now-defunct computer company started by Steve Jobs after he was forced out of Apple in 1985.

In December 1990, the program "WorldWideWeb" was first made available within CERN.

But it was two things that Mr. Berners-Lee didn't do that made all the difference: He didn't patent his work and didn't sell it to a major corporation.

In 1991, he put his work out on the Internet and invited people to start making Web pages. And the World Wide Web exploded onto the scene.

Within five years, the number of people using the World Wide Web grew from 60,000 to 40 million. By June of this year, the Netcraft Web Server Survey (www.netcraft.com), which tries to contact every active Web site, received responses from more than 172 million Web sites with growth estimated at 3.9 million sites for the month.

And it all began with a little hack that Tim Bedrners=Lee decided to share with the world. Ta-Da! indeed.

A little Windows Vista trick

 Here's a little Vista trick I learned from the Windows Weekly podcast with Paul Thurrott of Winsupersite.com. If you hold down the Windows key and a number key, the proogram at the corresponding position on you quick launch bar will open. E.g. if Internet Explorer is the second item on your quick launch bar and you hold down Windows key and 2, it will launch. Handy for a keyboard addict like TechMan.

Xbox 360 fall update brings joy to good little boys and girls

Xbox 360 fanboys people will be overjoyed to learn that all sorts of creamy goodness is coming their way with the fall console update, including:

  • Play from the hard drive - copy your games directly to the hard drive to speed them up.
  • Xbox Live Marketplace access from a regular interneted computer.
  • Dashboard update makes game access a bit easier.
  • LIVE Party allows for up to eight people to be grouped together from game to game without losing touch.
  • LIVE Primetime brings real prizes to some games.
  • Avatars - gamer tags evolved into gamer cards.  Now gamer cards are evolving.
  • Display support for 16:10 screens over VGA or HDMI

Can't wait to try this out myself.  I can tell you that the LIVE Party idea will be welcomed by a good many folks.  If you've ever been marooned during the launch of a Call of Duty 4 game, you'll know what I'm talking about.
