Computer code is all around us and powers every electronic device. As an exercise for those who may have never seen a code before, hit F12 (Internet Explorer), Ctrl+U (Firefox and Chrome), or Cmd+Opt+U (Safari) to see the source code for this webpage.
In an increasingly digital age, learning computer skills is a fundamental necessity, and learning programming is like learning the language. Learning to code has never been easier, and everyday more resources are popping up to teach you how. Currently, there is a high demand for programmers in the job market. This post is dedicated to giving you some of those resources.
Learning to Code
Python is a great place to start programming. This scripting language is expressive and easy to understand. The Python community has come together to create tons of libraries and tutorials to get you started and beyond.
Scratch is a graphic programming language that teaches users the basics of object-oriented programming (OOP). This program was created by MIT and teaches you to create games and animations. Check out Learn Scratch to get started. Teachers interested in including Scratch into curriculum may be pleased to note the 'Lesson Plans' section.
Alice Developed by Carnegie Mellon University, Alice is similar to Scratch and teaches users OOP in a 3D environment through the use of storytelling.
Happy Nerds Want more? Happy Nerds has put together a fairly comprehensive site with more resources for learning to code for various platforms.
SmallBasic is based on Microsoft's .NET programming language. The SmallBasic language editing software (called an integrated development environment, IDE) allows you to break problems down into small steps and test each one along the way, in other words: teaching you how to think like a programmer.
The library has a Code Club for teens who are interested in learning more about coding and meeting others who share the same interest. Click Here for more information.
Click here to check out programming books that the library has in its collection.
Check back next time for part two where we teach you the skills to design and implement your own computer and mobile apps.

Take some time to let this map load, and be sure to check out all its features. This week's topic is a rather difficult one, so take some time and explore all that it has to offer.

What is GIS?!
Geographic Information Systems, or GIS, are systems that store, analyze, and graphically present geographic data, called spatial data. Map presentations (like the one featured above) are created by adding layers of data onto a base map.
In the example above, I started with a map of the US, and then I added a shapefile containing a map of all the counties of KY. Next, I added a layer containing all of the farmers markets in the US and a final layer that shows the diversity of crops harvested per county in the US. This simple map shows the relationship between the density of farmers markets and the agricultural productivity of KY counties.
Maps like this one can be analyzed to better understand that relationship, and information like this may be important to farmers looking to corner new markets. In fact, GIS is a very large field that encompasses many disciplines of study like science, the environment, infrastructure, business, social studies, history, geography, and geology. Many jobs are available to people with strong GIS skills, as well.
Below are some resources to get you started in this exciting field.
Free Map Making Software
Here are some free applications that allow you to access data and make maps:
ArcGIS Explorer Desktop
ArcGIS Explorer Online
Your map is only as good as the data that you have to display. Whether or not you realize it, KY is in the top 5 states in the nation for GIS data! Here are bunch of great place for fast, free data:
KY Geological Survey - offered through the University of KY, the KGS is the repository for a wide range of KY Geospatial data
Geospatial Data Library - this is the KGS library of data including links to the KY Geonet, Office of Geographic Information Systems, KY Dept Fish and Wildlife, University of Louisville GIS, the US Geological Survey, and more.
You've got all the tools you need, now what?! Watch some of these videos to get you started:

ArcGIS Explorer Quick Start Tutorial
If you are looking to take these skills to the higher level, be sure to check ot some of the GIS courses offered through My Library University.

Amateur researchers and science enthusiasts have aided in scientific research projects for quite a long time. For example, members of the John James Audubon society have participated in bird counts to aid in conservation efforts for over a century.
This method called 'citizen science,' or 'crowdsourcing,' is the systematic collection and analysis of data. It can work in several different ways, like citizens collecting data for researchers to analyze or citizens analyzing the data that researchers have collected.
Below are some web applications that let you be the guinea pig and help science--consider it micro-volunteering!
Solve puzzles by shaping RNA nucleotides and help scientists unlock the secrets of genetics.
This one is for all you math-letes out there. This project posts mathematical equations and relies on the crowd to solve them.
Encyclopedia of Life
We looked at EOL in Tip #15. Now you can help by contributing or checking the accuracy of species photos.
This science-project-turned-gamed aims to study the nature of protein structures with the hope of classifying new virus-fighting or CO2-cleaning proteins.
Here you will find more than a dozen research projects broken into the following categories: space, climate, humanities, nature, and biology.
As a sneak peak, Facebook will soon release an app that let's members 'like' a certain whale shark and track conservation efforts.

Using Chroma Key
Using a green screen is a fairly simple process that can be done with a green cloth or brightly painted wall.
First, record a person or subject in front of the green screen and add it your video editing software. Next, you will need to utilize a tool called chroma key to remove the green leaving just the subject. (Tip: don't wear clothing that is the same color as the green screen, or else the background will bleed through.)
Next, add another background image or video clip in the same time frame on the storyboard of your video editing software to place the actor in a new background. (If you zoom in on your actor, be sure to zoom in on the background to match.) Adjust your sound levels and export your clip.
Free Video Editing Software
Here are some freely-downloadable software programs that have a chroma keyer:
