In one sentence, describe what the following article is about: There are a wide variety of cleaning products you can use to help clean your vinyl fence. Two of the easiest to use, though, are vinegar and household dish detergent. Both are effective, cheap, and safe to use.  Vinegar is a great natural product that you may already have at home. Mild dish detergents, like Dawn, will help cut through mildew, dirt, and more. After you’ve decided which cleaning agent you want to use, you’ll need to mix it with water to create your cleaning solution.  If you choose vinegar, take 1 cup (240 ml) of vinegar and add it to 2 gallons (7.57 L) of water. If you choose dish detergent, take several tablespoons of detergent (depending on the brand) and add it to 2 gallons (7.57 L) of water. Take a rag or other cloth and soak it in your solution. Use it to wipe down your fence. Make sure you wipe down your fence good and get as much dirt and grime off as possible.  Go back and forth or in a swirl-like fashion to make sure you properly clean every portion of the fence. Make sure you have enough clean rags, so you can switch dirty ones out for clean ones as you need. You may want to use a bristled brush to scrub extra dirty sections of the fence. Consider using an extra bucket full of water to rinse your rag after you wipe down a section of the fence. Use a hose with a sprayer nozzle to rinse your fence. Start at the top and move horizontally across and allow the water to wash debris downward. Slowly move down the fence, continuing to move in a horizontal direction. Without rinsing your fence, your cleaning solution and other dirt will set and your fence won’t appear clean.
Summary: Choose between vinegar and detergent. Create your cleaning solution. Wipe down your fence. Rinse your fence.

In one sentence, describe what the following article is about: Try to lower your shoulders away from your ears to activate your latissimus dorsi, which is your upper back muscle. Move your shoulder blades closer to your spine to help engage the muscles so it’s easier to lift your bodyweight.Once you engage your shoulders and back, keep your body straight since it will be easier to control your movements. Maintain your position so your muscles stay engaged. Don’t forget to breathe while you’re at the top of your pull-up, or else you may feel more winded. If you feel like you can’t keep holding your head over the bar, lower yourself back down slowly. Slowly straighten out your arms and bring your head back below the bar. Keep your body rigid so it doesn’t swing or move around during the exercise. Once you straighten your arms, relax your shoulders again to finish your rep. Take a second to congratulate yourself and celebrate completing your first pull-up.
Summary: Bring your shoulders together to engage your muscles. Hold your head over the bar for 1 count. Lower yourself back down so your arms are straight.

In one sentence, describe what the following article is about: 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.
