In one sentence, describe what the following article is about: Polaris, also called the North Star, can be used in the Northern Hemisphere to help you find north. This is one of the quickest ways to determine your directions at night if you don’t have a compass or GPS. Polaris, or the North Star, is not one of the brightest stars in the night sky (it clocks in at 48th brightest). It is, however, the brightest star between the Big Dipper and Cassiopeia.  Because it’s located in the sky around the North Pole, it doesn’t move around much, meaning it’s useful and accurate for navigating. Find the Big Dipper (also known as the Plough) and the Little Dipper (aka Ursa Minor). Think of the Big Dipper like a ladle (hence the name), where the handle holds a cup, and the outer edge of the cup (the farthest from the handle) points out into the sky and toward Polaris. For confirmation, Polaris is the last star that makes up the handle of the Little Dipper. This is approximately true north. When you face Polaris, you are facing due north; behind you is due south, and due west will be on your left, while due east will be on your right.
Summary: Recognize Polaris. Locate Polaris. Draw an imaginary line from Polaris to the ground.

In one sentence, describe what the following article is about: Use a Dremel-style rotary tool to smooth down the rough edges of the metal. Make sure that the tool has been fitted with a round bit designed for use with soft metal.  If you inspect the edges of the knuckle duster, you should notice the presence of harsh grooves. The dip of each groove comes from the original drill holes you made, and the point corresponds with the punched-out space in between those holes. Focus the bit of the Dremel tool over the point of each groove. Sand down the point until it feels smooth and blends into the dip of the grooves around it. If you have difficulty filing down the edges, hold the knuckle duster in a vise grip as you work. Wedge a piece of paper or cloth in between the metal and the teeth of the grip to prevent the metal from getting scratched. Once most of the metal grooves have been filed down, you can use metal files to make the edges even smoother.  Use a round file to work on the grooves inside each finger hole and a triangle file to help create the notches in between the finger holes from the outside. You can use a flat file to work on the remainder of the outer edge. You can technically file down the entire knuckle duster without using a Dremel tool as long as you use these files to do it. Smoothing down the edges will be much more time consuming without the use of power tools, however, so it is not recommended. As before, you can hold the knuckle duster using a vice grip as you continue to file down the edges. Even though the edges should look notably more rounded after you finish filing them, you should still make them even smoother by grinding them down with sandpaper.  You can sand the edges by hand. You do not need to use a sanding belt or other power tools for this part of the process. Work in steps. Start with a large grit sandpaper, like 60 or 80 grit, and work around the edges until you're satisfied with the results. Gradually work through different grits in this manner until you reach a fine grit like 320 or 400. If desired you can finish the sanding with fine-grit wet/dry sandpaper. Doing so is only optional, though, and may not be needed if the edge already seems smooth enough. Grab a pad of #00 steel wool and buff the surface of the metal, working in small, circular motions. Work your way around the entire surface on both sides of the piece.  You can buff over the edges, too, but doing so shouldn't be necessary at this point. Focus your energy and attention on buffing the flat metal surfaces during this step. When finished, the metal should appear less dull and more polished. Spray or wipe metal cleaner over the entire piece, working over the flat surfaces and the edges.  You can use either metal cleaner or metal polish. Either way, make sure that the product you choose is approved for use with aluminum so that you do not accidentally tarnish or otherwise damage the metal. Thoroughly work the product into the metal. Continue polishing and shining with a soft cloth until the surface of the metal is no longer moist from the cleaning spray. At this point, the knuckle dusters should be complete and ready to wear. Put them on and see how well they fit.  Your fingers should fit comfortably into the finger holes and your hand should be able to bend over the base of the knuckle duster while it's on. You won't be able to make any changes to the piece if it is too loose, but if it feels too snug, you might be able to widen the finger holes slightly depending on how thick you left the metal around each hole. If you do make any changes, it is best to do so by filing the metal down with a Dremel tool or file instead of attempting to punch or saw it away.
Summary: Smooth down the grooves. File the finer details. Sand the edges. Buff the knuckle dusters. Apply metal polish. Try them on.

In one sentence, describe what the following article is about: Visit pandora.com and click "log in" to sign in with your Pandora account. If you don't have a Pandora account, you can create one for free from the Pandora homepage. See Make a Pandora Account for more detailed instructions. You'll need to be playing a song in order to like it. You can enter a song, artist, or genre into the "Create Station" field in the upper-left corner to begin playing music. When you're using the website version of Pandora, you can only Like or Dislike songs. There is no "Bookmark" feature like there is on mobile devices. When you like a song, it will appear in the Likes list on your mobile device instead of the Bookmarks list. Even though they have different names and are found in different places, Likes and Bookmarks generally act the same way. You'll find this underneath the album art or band picture. Even though this has a picture of a Thumbs Up, and it adds the item to your Likes list, this is not the same as giving the song a Thumbs Up while it is playing. It will not affect how your stations are created like giving a Thumbs Up does. This will open your profile page. This will display the songs, artists, and albums that you have given a thumbs up for. You'll be able to see lyrics, features, similar tracks, comments, and links to buy. This will remove the song, artist, or album from your Likes list. These are the bookmarks you created on the mobile app or on the old version of the website; it is not possible to add bookmarks from the current version of the Pandora website. Click the ▼ button next to the "Play a Sample" button and select "Delete" to remove the bookmark from your list.
