QR Code Reader is a basic application that allows the user to read QR codes and take action depending on the information stored in them. There are many good applications available that are capable of this function, but this one doesn't seem to be one of them.

Once QR Code Reader has been downloaded it opens quite sluggishly. On the Samsung Galaxy Nexus it took 15 seconds to open the application. For such a small application this delay seems unexplainable. The user interface features no controls. It simply displays a viewfinder window that must be lined up with the … Read more

QR codes haven't exactly set the world on fire, yet most people know what they are, and most phones can scan them, either out of the box or with a third-party app.

The Findables Case takes that idea to heart by emblazoning a unique QR code on each hard-plastic shell, the idea being to use that code to share information about yourself or help recover your lost phone.

In other words, your case can now take the place of your business card, while at the same time offering good Samaritans a means of contacting you (that doesn't involve poring through your address book).

When someone scans the code, they'll see one of three profiles (chosen by you via a companion app or the Findables Web site): Business, Social, or Lost.… Read more

As the father of a 5-year-old girl who adores all things princess but also digs stars and comets and mastered the user interface for both Android and iOS in about half a day, I'm always on the look out for Geek Grrl role models. So the new hero in my household is Jennie Lamere.

This 17-year-old grrl loves both reality television and hackathons and tapped into those two passions to win the grand prize at the TVnext hack event in Boston last month. Her brilliantly simple hack, first detailed on evolver.fm, is designed to prevent spoilers on Twitter while watching live TV.

Surely we've all shaken our fists in the air when a fellow "Walking Dead" or "Game of Thrones" fan in a different time zone tweets about the latest character to get eliminated while you're still popping popcorn and getting the couch ready for the evening's gore-fest.

Lamere's Google Chrome app, Twivo, allows users to block any tweets related to a certain keyword or words for a specified period of time, allowing you to keep up with the rest of the Twitterverse during commercial breaks without ruining the show you're watching.

Technology has tiptoed into kids' pajamas with onesies covered in QR codes that link to bedtime stories.

"It's time for bed, Tommy. Brush your teeth, put on your PJs, and let's scan you."

Smart PJs, called the world's "first and only interactive pajamas," require downloading a free app for iOS or Android and scanning one of dozens of codes from the Smart PJs with a smartphone or tablet. The device then reads aloud a story, sings a lullaby, or broadcasts pictures of animals or other bedtime-appropriate cuteness. … Read more

Is there any greater test of one's patience than dealing with local government? Whether waiting in line at the DMV, applying for a building permit, or fighting a parking ticket, I'm always left wondering why there isn't an app for that. Now cities are getting a high-tech boost thanks to Code for America, a nonprofit organization founded by Jennifer Pahlka.

Since 2011, Code for America has awarded fellowships to a carefully chosen group of tech professionals and paired them with cities across the U.S. that are looking to improve the way their government is run, whether … Read more

Apple's suppliers have achieved a new compliance mark for employee hours, according to the iPhone maker.

To shed light on how its suppliers are behaving, Apple launched its Supplier Responsibility page early last year. This page attempts to show how suppliers are faring with such issues as excessive overtime, underage workers, and other violations of Apple's Supplier Code of Conduct.

Compliance with the 60-hour work week limit varied throughout 2012. But in January, the rate reached a record of 99 percent, Apple revealed yesterday on the Supplier Responsibility page

Hey, kids: coding is cool -- so cool that everyone from Facebook Chief Executive Mark Zuckerberg to NBA baller Chris Bosh wants you to do it.

The celebrities are using their star power to draw attention to Code.org, a nascent nonprofit foundation that seeks to cultivate computer programming education in schools and direct people to online coding tools.

Zuckerberg and Bosh join hip-hop artist Will.i.am, Microsoft legend Bill Gates, Twitter creator Jack Dorsey, and others in a new YouTube video designed to get students, and their teachers by association, excited about coding. The video is directed by … Read more

The Computer History Museum has made the source code for Photoshop 1.0.1 into an exhibit that lets the public, or at least programmers, appreciate the inner workings of the historic software.

The museum published the software yesterday, following up on its earlier release of the source code underlying Apple's original MacPaint.

Source code is what humans write -- in Photoshop 1.0's case the brothers Thomas and John Knoll. The initial Photoshop is written in written 128,000 lines of code, a combination of the high-level Pascal programming language and low-level assembly-language instructions. When converted to … Read more
