Q: As the oven is heating up, line your baking sheet with parchment paper. If you don't have any parchment paper, non-stick cooking spray will do in a pinch, or a little melted butter. You want it to be soft, but not liquidy. Room temperature should be fine, as it will be easy to blend. If you need, put the butter briefly in the microwave — 4-5 seconds, tops. Mix everything well so that there are no clumps and everything is well distributed. Cream of tartar leads to a light tang and helps the cookies get fluffy. However, if you want crispier cookies or don't want this tangy edge, you can skip the cream of tartar. Mix the butter/margarine and sugar together until fluffy. Keep your electric beaters on medium speed and work the softened butter until it is a nice whipped, semi-stiff mixture. All of the sugar should be incorporated into the butter. This should only take 3-5 minutes of mixing. Keep the mixer going until the eggs are completely incorporated into the butter mixture. Use a rubber spatula to scrape the sides of the bowl as necessary, making sure everything is well mixed. Want tangier, less sweet cookies? Skip the vanilla. Add the flour in small chunks, keeping the mixer going the entire time. This prevents flour "explosions," where the beaters scatter the flour instead of mixing it. As you add flour, keep scraping the sides of the bowl to make sure everything is getting added in. After dough is thoroughly mixed, chill it for 30-45 minutes to guarantee the best results. Start with 2 tablespoons of each, adding more as necessary. Feel free to play with this ratio as well -- while few chefs use more cinnamon than sugar, many will add a few extra parts sugar to avoid overly spiced cookies. You can use a small spoon to measure out the dough, then roll it between your palms to form the dough balls. You then roll the dough in the cinnamon sugar to coat it completely. Make sure the cookies are at least 2 inches apart, as they will flatten and spread as they cook. A good snickerdoodle has a light, chewy texture, not a crunch. You want to try and keep the tops of the cookies light, so remove them when the outsides are just getting golden for the best cookies. Let them cool on the baking sheet for 2-3 minute before eating.
A: Preheat the oven to 400 °F (205 °C). Let the butter soften outside the fridge for 5-10 minutes. Whisk together the flour, cream of tartar, baking soda, and salt in a large bowl. Using an electric mixer, cream the butter in with the sugar until completely mixed. Add the vanilla extract and eggs and beat for 2-3 minutes. Turning your mixer to "low" speed, slowly add the flour mixture. In a shallow bowl, mix equal parts white sugar and ground cinnamon. Roll the chilled dough into 1" wide balls, then roll each ball in cinnamon sugar. Set the cookies on the parchment-lined baking sheets and cook for 8-9 minutes. Remove from the oven when the outside edges are just turning golden.

Q: Almost all app-creation programs will require you to create an account and log in before you can get to work. You may need to download software, or apps may be created entirely through the website. After logging into the creation tools or downloading the creation software, you will need to start a new project. The process varies from program to program, but generally involves naming your app a name and description. Most app development programs will ask you to set a basic theme and color palette before you begin building the app. You will be able to change these choices later once the app is under construction. You may be able to add your own images for screen backgrounds. These images should typically be 1024 X 768 px. Most app creation programs work by letting you add prebuilt functions into your app. The combination of these functions and how they link together is what will make your app yours. There are a variety of different functions you can add to your app, including calendars, photo galleries, podcasts, Facebook integration, audio players, and more.  Typically, each one of these functions will be its own screen on your app. As you add functions, you will be able to customize each screen with your own text and content. For example, if you add an RSS feed function, you can link to your blog's feed and automatically populate the app with your latest posts. After you've added a few functions to your app, spend some time organizing the layout of each screen so that you have a cohesive look for your app. Your title bars should all be in the same location, and content should appear in consistent parts of the screen. Different app creation programs will give you different levels of control over how everything is laid out. Some apps only let you add completely prebuilt functions, while others allow you to drag and rearrange each element on the screen. You will have the opportunity to assign icons to each of your app's functions. Many app creation programs have a library of icons you can choose from, or you can design and upload your own. Good icons will help set your app apart and contribute to the overall feel of the app.
A: Log in to the program you choose. Start a new project. Choose a theme. Add functions, or activities, to your app. Adjust the layout of each of your screens. Choose icons for your functions.

Q: Position the slat support on the inside of the outer board so that the top of slat support is even with the top of the support post. Check for level and secure the slat support in place with seven 2 ½" screws. Position the second slat support on the inside of the sideboard so that the top is even with the top of the support post. Check for level and secure the slat support in place with seven 2 ½" screws. Position the end support on the inside of the headboard so that the top of the end support is even with the top of the side slat supports. Secure it in place with four 2 ½" screws. Position the end support on the inside of the footboard so that the top of the end support is even with the top of slat support and the support post. Secure it in place with four 2 ½" screws. Measure and mark the locations of the fourteen slats, creating even spacing along the slat support. Attach each of the 14 slats by drilling a pilot hole at each end into the side slat supports and securing them with two 1 ½" screws.
A:
Position and attach the first slat support. Position and attach the second slat support. Add the first end support. Add the second end support. Add in the slats.
