INPUT ARTICLE: Article: Ubuntu previously recommended installing Skype using the Canonical (Ubuntu developer) repository instead of the packages from the Skype website. This will ensure that you get the proper version for your system. The Terminal may be intimidating, but you'll just need to enter a couple different commands. You can quickly open the Terminal by pressing Ctrl+Alt+T or by opening "Applications" "Accessories" "Terminal". You'll need to know this before proceeding so that you can install the correct software. Type sudo uname --m and press Enter. Type in your administrator password. If the Terminal returns i686, you are running the 32-bit version. If the Terminal returns x86_64, you are running the 64-bit version. This allows for better compatibility with programs compiled for other computers. Type sudo dpkg --add-architecture i386 and press Enter. Type in your administrator password to download the package. This will give you the ability to install any of the programs hosted on this repository, which includes the latest versions of Skype. Type or paste sudo add-apt-repository "deb http://archive.canonical.com/ $(lsb_release -sc) partner" and press Enter. Now that you have the proper dependencies and the Canonical partner repository, you can download and install the Skype software. Type sudo apt-get update && sudo apt-get install skype and press Enter to install Skype. The installation process may take a few minutes to complete. You can also install Skype using the Software Center since you've added the Canonical partner repository. Open the Software Center, search for "Skype", and then click the "Install" button to download and install it.

SUMMARY: Open your Terminal. Determine if you're running the 32- or 64-bit version of Ubuntu. Enable MultiArch if you are running 64-bit Linux. Add the Canonical partner repository. Install Skype.

In one sentence, describe what the following article is about: This is a basic method for drawing a sphere, so minimal materials are needed. Sketch pad or paper Pencil Cotton balls or tissues Circular object You can use a small bowl, a glass, a mug, or another object with a circular shape or base. Tracing the circular object allows you to focus on shading the sphere rather than on learning how to draw a perfect circle. Once you decide the angle from which your light source will come, draw an arrow toward the circle from that direction. You will later leave an untouched spot on the sphere, below that arrow, to signify the highlight from the light source. Avoid pressing too hard with your pencil while you shade, as this is your first layer of shading. You will add additional layers of darker shading in later steps. Leave the circular or oval-shaped spot untouched, below where the arrow points from the direction of the light source. Gently rub over the light shading, taking care not to smear the graphite out of the edges of your circle. Remember to leave your highlight spot untouched, so also take care not to smear graphite into that area. Gently shade again around most of the circle, making darker shading on the sides of the sphere where the light source cannot reach. This shading is called the mid-tone. Around the middle of your sphere, you should have about medium tones of shading. Again, take care to avoid smearing the highlight spot and smearing outside the edges of the circle. The light source cannot reach these areas, so naturally, they should be darker. As you get further from the light source, the shading should get darker. However, they should not be as dark at the space directly below the sphere. Maintaining a smooth-looking sphere is important in order to help it look realistic. Use your cotton ball or tissue to do this. This is the final shading step, creating the core shadow. Shade the border moderately dark, and taper it into a crescent shape before tapering off on the other side. Keep this darkest area of shading close to the bottom edge of the sphere; it should be no more than centimeter in thickness. This will help to blend the core shadow into the rest of the sphere. You might also have stray line marks that went outside the edges. Take care not to erase anything within your sphere.
Summary: Gather the materials you need to draw the sphere. Trace your circular object on the paper. Choose where your light source will be. Fill the sphere with very light shading. Smooth the shading with a cotton ball or tissue. Add more shading to areas of the sphere that the light source minimally reaches. Repeat smoothing out the shading with a cotton ball or tissue. Darken the outer edges of the sphere, particularly on the bottom and opposite side of the light source. Smooth the darkened shading again. Make the crescent edge opposite the light source the darkest. Rub your cotton ball or tissue over the dark crescent at the bottom to smooth it one last time. Clean up the edges of the sphere by erasing any smudges that escaped the edges.

INPUT ARTICLE: Article: The easiest way to feed butterflies in a habitat is with Gatorade or another already-prepared juice drink. As is, Gatorade and fruit juice have the sugar and water needed in order to provide nutrients to your butterflies. Use these for food if you want to be able to feed your butterflies quickly and easily. If you're willing to put a little more time and effort into your butterfly food to ensure maximum nutrition, make your own food solution. Mix 3 ounces (88.7 ml) of water or Gatorade with 1 teaspoon (4.9ml) of simple syrup. Then, add in 6 drops of soy sauce. To make your own simple syrup, add 1 cup (240ml) of sugar to 1 cup (240ml) of water. Almost bring the mixture to a boil, but remove it from heat just before it starts to boil. To make the food appealing to your butterflies, you'll need to serve it in a proper container. The smaller and shallower the container is, the better. Opt for a saucer or bottle lid if possible. Simply fill the dish or container, lower it into the habitat, and close the habitat. You can also use a small cup or a candle votive, but since these options are deeper, make sure to fill the container with marbles for the butterflies to stand on while they eat. Fruit serves as an adequate food source for all different types of butterflies, so this might be the best option if you have a variety of species in your habitat. Take a skewer or a piece of bamboo and slide chunks of fruit onto it. Then, set it in the habitat. If the fruit won't stay on the skewer, secure a bread twist tie underneath the bottom piece of fruit. Butterflies instinctually gravitate towards bright areas, so they'll have an easier time finding the fruit if it's located in a brighter part of their habitat. Place fruit skewers horizontally on the butterflies' habitat floor or set them up vertically in a corner in the brightest part of the habitat. They should be able to find and consume the food themselves.

SUMMARY:
Use Gatorade or fruit juice as an easy solution. Make your own creative butterfly food solution to get the best results. Serve liquid food in a small, shallow container for easy access. Provide skewered fresh fruit when you have several butterfly species. Place fruit in the brightest area of the habitat.
