Hints after video one. This may never be seen? Draw a picture made of ellipses and rectangles! For example, you could make a self-portrait, an alien creature, or something more abstract. It'll just be black and white for now, we'll get to color in the next video. You can work on your own pace, but we recommend approximately ten minutes on this assignment before moving on. Reminders To draw a rectangle: rect(a,b,c,d); To draw an ellipse: ellipse(a,b,c,d); a — X (horizontal) location of the shape's upper-left cornerb — Y (vertical) location of the shape's uppper-left cornerc — width of the shaped — height of the shape For more, check out the rectangle and ellipse pages on Add color to your design! You can build off the example below or add to your previous design by selecting "My Code from Last Lesson" under the "Code" menu below. Reminders Set the background color: background(r,g,b); Set the outline color: stroke(r,g,b); Set the interior color: fill(r,g,b); rect(250,200,100,75);

Front End Developer Playground & Code Editor in the Browser Three-way MV* Data Binding with AngularJS and Firebase One of the hallmark features of the AngularJS framework is its "two-way binding" of data, a trick that makes handling dynamic data in a single page application (SPAs) fast... Grokking quadratic bézier curves in SVG DIY 360 Degree SODAR Device First off, why did we decide to call this thing SODAR? SOnic Detection and Ranging, or SODAR, is a lot like SONAR and RADAR. However, we don't feel comfortable calling it SONAR because we have no desire to use it for navigation and we aren't under water. Also, it's definitely not RADAR as we are using ultrasonic pulses, not radio waves to find objects.

Gold Recovery Wait don’t throw those old electronics in the garbage, there’s gold in them there things. How about putting it in your pockets instead of someone else’s pocket? Laptops, phones, cameras, and the like are filled with gold plated circuit boards even printers and scanners have gold, silver, and copper, even platinum in them. Gold is a precious, conductive, and pliable metal that retains a stable value better than many commodities. Its chemical properties make it useful for the manufacture of computers parts and electronics. Some people find it profitable to attempt to extract the gold from these scraps, then refine and sell it.

Librarian Approved: 30 Ed-Tech Apps to Inspire Creativity and Creation Tool discovery is often a challenge for teachers interested in finding ways to use technology that will change the way they and their students work. With so much going on in the classroom, many teachers don’t have the time to test out various apps and find the perfect tool to meet their needs. Luckily, several tech-savvy librarians have been curating the apps their colleagues find useful and sharing the all-stars with one another through personal learning communities (PLC) and edWeb webinars.

Programming 3D Applications with HTML5 and WebGL WebGL is the standard 3D graphics API for the web. It allows developers to harness the full power of the computer’s 3D rendering hardware from within the browser using JavaScript. Before WebGL, developers had to rely on plugins or native applications and ask their users to download and install custom software in order to deliver a hardware-accelerated 3D experience. Construct 2 - the HTML5 game I’ve been experimenting with Construct 2 from Scirra the last few days. Construct 2 is a program from creating HTML 5 games. What really got my interest was that there is the ability to create Windows 8 games using Construct 2 with Visual Studio 12. The Construct 2 development environment is pretty easy to use and I find that some similarities to Visual Studio (among other tools) is helpful in finding ones way around it.

Ali Partovi: Why Learning to Code Is Imperative In Public Education “Education is about preparing kids for life, and public education is about helping people have equal opportunity, helping those who don’t have as much money have a more level playing field,” said Ali Partovi, co-founder of, in an interview at the Big Ideas Fest a few months ago. Partovi has an ambitious goal: To get public high schools to offer computer programming classes — not just as an elective, but as a science requirement. “It’s absolutely relevant for public education to embrace computer science,” he said. “I can’t think of any other science that would better prepare you for life in the 21st century.” 10 Excellent Platforms for Building Mobile Apps If you've ever wanted to build an app for your business, blog, product or service, but the heavy investment of both time and money put you off, you're not alone.
