Sound Representation This activity involves listening to songs and finding hidden messages based on the same principle as a modem. The binary number activity briefly mentions how text could be coded using sound -- high and low beeps represent binary digits, which in turn can be decoded to numbers that represent the letters of the alphabet. There are three sets of songs provided here. "Songs" that decode to English "Songs" that decode to Chinese To decode the songs, transcribe a 1 for each high note, and a 0 for each low note. The major challenge is in the video "Reaching out" (below, and available for download from vimeo.com/23952295), which contains over 20 hidden binary message in total. The names of the first few people to decode various parts of the music video will be posted here; the hidden messages in the song tell you how to get your name here! The very first correct decoding was completed by a family team effort: The Engelberg Family (Mark, Alex, Mindy and Molly) from Everett, Washington, USA.
Algorithm An algorithm is a step-by-step list of directions that need to be followed to solve a problem. The instructions should be simple enough such that each step can be done without thinking about it. Algorithms are often used to describe how a computer might solve a problem. But there are algorithms in the real world too. Comparing algorithms[change | edit source] There is usually more than one way to solve a problem. In cooking, some recipes are more difficult to do than others, because they take more time to finish or have more things to keep track of. Sorting by colors[change | edit source] This is an example of an algorithm for sorting cards with colors on them into piles of the same color: Sorting by numbers[change | edit source] These are examples of algorithms for sorting a stack of cards with many different numbers, so that the numbers are in order. Players start with a stack of cards that have not been sorted. First algorithm[change | edit source] First pass: ( 5 1 4 2 8 )

Your Neopet Dailies There are lots of special activities on Neopets that you can visit that are called "dailies", usually since you can visit them once a day. Since there are so many to earn Neopoints from, we've created a useful list below of all the places you could be visiting. :) If you login to your jnAccount and add the "Your Dailies" service, you can customize this list to pick which dailies to include, and even add in your own custom dailies! Tip: Bookmark this page by pressing CTRL + D or CMD + D on your keyboard! You can come back everyday to complete these dailies again. Neopets Dailies Are we missing a daily you'd like to see here?

Part 4: Introduction to XAML | Windows Phone 8 Development for Absolute Beginners Source Code: PDF Version: In this lesson, I want to talk about the XAML syntax we wrote in our first pass at the SoundBoard app. Hopefully you could see how the XAML we wrote impacted what we saw in the Phone preview pane. It's relatively easy to figure out the absolute basics of XAML just by looking at it, but I want to point out some of the features and functions that may not be obvious at first glance. At a high level, here's our game plan in this lesson: We'll talk about the purpose and nature of XAML, comparing it to C# We'll talk about the special features of XAML ... little hidden features of the language that may not become obvious by just staring at it My aim is by the end of this lesson you'll have enough knowledge that you can look at the XAML we write in the remainder of this series and be able to take a pretty good guess at what it's doing before I even try to explain it. 1. XAML is a special usage of XML. 2.

Teaching Kids to Code Every era demands--and rewards--different skills. In different times and different places, we have taught our children to grow vegetables, build a house, forge a sword or blow a delicate glass, bake bread, create a soufflé, write a story or shoot hoops. Now we are teaching them to code. We are teaching them to code, however, not so much as an end in itself but because our world has morphed: so many of the things we once did with elements such as fire and iron, or tools such as pencil and paper, are now wrought in code. We are teaching coding to help our kids craft their future. In this collection we share many different perspectives on coding, from a university professor's vantage point (MIT's Mitch Resnick describes why learning to code is like learning to learn) to an entrepreneur's reflections from his cross-country roadtrip to bring coding--and his stuffed dog--to classrooms across the U.S. We should always teach children to bake bread, feed the goats and wield a hammer.
