INPUT ARTICLE: Article: You can add snippets of websites to your Dashboard, allowing you to easily keep tabs on your important content. You'll need to set this up through Safari. You'll be able to add just a portion of the website to the entire page, but it will be a static view (no scrolling). The website will dim, and your cursor will turn into a box that reveals the site. What's in the box will be displayed on your dashboard. Place the box in an area that you know will always display the content you're looking for. You can make the box any size you'd like within the confines of the window. You'll be taken to the Dashboard screen and your new website snapshot will appear. You can click and drag it to reposition it on the Dashboard screen. You can launch the Dashboard from the Launchpad in your Dock. Any links you click will immediately be opened in Safari. For example, if you created a snapshot of the main page of a forum, clicking any thread links will open that thread in Safari.

SUMMARY: Open Safari. Navigate to the website you want to add to your Dashboard. Click the "File" menu and select "Open in Dashboard." Click where you want the box to be on the site. Drag the corners of the box to resize it. Click the "Add" button to add the selection to the Dashboard. Open the Dashboard to view the snapshot. Click links in the snapshot to open them.

In one sentence, describe what the following article is about: Taking measurements is necessary if you plan on filling a large space. Use measuring tape to figure out the length and width your new slab needs to be. Write your measurements down so you know what supplies to get to pour a smooth, consistent slab later. If you are only going to pour a thin slab or patch up existing concrete, make a general estimate of the area’s size and how much concrete you need for it. You can usually mix and pour a small batch without setting up a perimeter. Slab thickness is important and depends on your plans for your home. If you want the slab to reach up to your doorstep, for instance, you need to measure from the existing slab to the bottom of the doorstep. Use chalk to mark the height the slab should reach. Take your time measuring. The ground beneath the existing concrete may not be level, so measure on all sides. Measure the length, width, and depth of the area you wish to fill. Multiply these numbers together to get a general estimate of the amount of concrete you need. Add an extra 10% onto your total estimate to account for spillage. The calculation can be an imperfect estimate, especially for areas that aren’t perfect squares or rectangles. Always get more concrete than you need to ensure you have enough. Using your measurements, cut some boards to help hold the liquid concrete in place. You can get wood boards that will reach the depth marks you made in chalk earlier. Set the braces up around the perimeter of your old concrete slab.  These braces serve as a mold. When you pour the concrete into it, you no longer have to worry about it spilling off the old slab and making a mess. It gives you a better chance at creating a strong, level slab. You can cut the wood yourself with a circular saw. Wear protective gear, including a dust mask and eye protection, if you do this. Alternatively, get the wood cut at a home improvement store. Dig out the soil around the braces, then stand the stakes in them. You can use 2 in × 4 in (5.1 cm × 10.2 cm) wood for most projects. Place the stakes approximately every 12 in (30 cm), then drill them to the braces with 3 in (7.6 cm) wood screws.  Make sure the stakes are planted firmly in the dirt so the braces don’t fall as you work. If your slab won’t be very high, you may be able to lay the wood braces on the ground and screw them together without using stakes. The braces should be even before you begin pouring the concrete. Set the level on top of each board 1 at a time. Watch the liquid in the center of the level to make sure the bubble stays in the center. If the bubble moves to 1 side, that side is lower than the other side and needs to be adjusted. Another way to test the boards is to run string behind them. The string should be the same distance from the board at all times. If 1 end is closer to the string than another end, the brace isn’t straight and should be adjusted. Wire mesh provides extra strength to thick concrete slabs. You can purchase a roll of welded wire mesh at a home improvement store, then simply spread it out in a single layer over the old concrete. Press it down so it is flat and level before you add the new concrete.  The new concrete you pour binds to the mesh. Although it makes the concrete stronger, it won’t prevent it from cracking. Another option is to get rebar and lay it out in a grid pattern similar to the mesh. Place rebar chairs underneath the rebar to hold them in place.
Summary: Measure out the space you wish to fill with concrete. Mark the height you want the concrete to reach. Use the measurements to calculate how much concrete you will need. Install braces around where you will pour the concrete. Prop up the braces with wooden stakes. Test the evenness of the boards by laying a bubble level on top of them. Lay wire mesh between the braces.

INPUT ARTICLE: Article: Rise upward and forward simultaneously, and keep your spine straight, chest out, and shoulders back. As you post, lean forward about 30 degrees. Allow the horse’s motion to direct your post; remember to think of your core, hips, and legs as an extension of the muscles in the horse’s back. Don’t propel yourself with your feet or legs. You should only rise about 2 inches (5.1 cm) out of the saddle. Bouncing hard or propelling yourself with your feet can hurt your horse. Your legs should be relaxed; don’t squeeze the horse tightly or use your legs to keep your balance. That said, make sure your calves remain in contact with the horse’s barrel. This will help you avoid involuntary leg movements. If you don’t maintain control over your legs, you could accidentally kick your horse and confuse it. The pressure on your stirrups should remain steady as you rise and sit. Instead of bracing your ankles and forcing yourself upward, move gently up and down with springy, supple ankles. If you’re riding without stirrups, extend your legs and use your seat to balance. Scrunching up your legs can cause you to tightly grip the horse with your knees and thighs.

SUMMARY:
Post forward at a 30-degree angle. Keep your calves pressed firmly to the horse’s barrel. Maintain steady pressure on your stirrups if you’re using them.
