In springtime, people's fancies may turn to love, but their to-do list turns to cleaning. Make this the year that you finally recycle all the ancient MP3 players, toner cartridges, ethernet cables, and bulky monitors out of the closets, garages, and spare rooms where they've been lurking. Your home will feel more modern, and you'll be doing your part to boost the 27 percent electronics recycling rate. Just in time for another spring constant, Earth Day. Before you get rid of any of your electronics The first step on your recycling journey: Make sure that none of your personal data will be leaving the house along with your soon-to-be-discarded electronics. If you're using Apple's iTunes to manage your digital music and video, be sure you deauthorize any device you're recycling. "But that computer is dead" is no excuse: Apple expects you to simply deauthorize all your devices via the iTunes app, then reauthorize the ones that are still alive If you're recycling a smartphone, do a complete reset of your phone to wipe out its data and restore it to its factory settings. Before you do this, however, make sure that you've got your data backed up someplace else If you're recycling a computer or a hard drive, don't just assume that deleting files will wipe the data off your system, because it won't. All it does is reformat the space on the drive, and the data can be snagged using tools designed for disaster recovery. Now, on to recycling Broadly speaking, you have three recycling options: You can drop off your unwanted stuff in person somewhere; you can ship it away; or you can donate it to a willing organization. Drop it off in person. The advantage to dropping off your gear is that you don't need to really plan ahead and print out prepaid labels (as you would if you were shipping things away); you just toss your stuff in the car and go Another option that's cropping up across the U.S. is the electronics recyc

In this tutorial, we are going to tell you the steps of creating and printing a single envelope. Also, you can save it for future use.

With the penny gone and the triumph of plastic over paper bills only months away, the research and development department of the Royal Canadian Mint has proposed going one step further: the death of hard currency altogether. Last week, the Mint announced the release of MintChip, a completely digital currency. "Money, as we know it, is fine for today, but tomorrow is a different story," says an introductory MintChip video. "MintChip is better than cash, since you can use it online."

"A not-so-futuristic world in which drivers, cars and roads operate in a highly connected network of instantaneous data got one step closer to reality today."

The open source hardware platform Arduino has been the central platform of my electronics class since the beginning of 2008 and I've learned a lot in that time. I use the Arduino to teach some basic programming and introductory electronics concepts. This course led me to create a website (http://electronics.flosscience.com/) to help support my students as well as others who might want to use this platform in education. Now I'm ready for the next step.

We're one step closer to the Robocalypse: a research team at Japan's Kagawa University has developed a robot that's able to "speak" like a human being. While talking robots are not new by any means, this model isn't using software but a set of mechanical, human-like vocal organs, for example artificial vocal chords or a tongue and lips that are made of silicone

Can We Fix Computer Science Education in America?

Doug, thank you for the link to the article. I just spent a few days in Boston with CS Educators at the App Inventor Summit and the issues discussed in this article now make more sense to me. The CS Principles project (csprinciples.org) looks like a huge step in the right direction. It "could" become the foundation of introductory CS courses in high school (AP) and in post-secondary. They have run 2 years of pilot courses and it looks promising. The next generation AP exam will likely be language agnostic - designs will likely be expressed in pseudocode and the course really engages with students (not just programming).
