A TV tuner allows you to connect your antenna or cable box to your computer, and then use your computer to watch and change channels using onscreen controls.   TV tuners for computers are available from most major electronics retailers or through online outlets such as Amazon and Newegg. Many TV tuners allow you to also record footage and save it to watch later, much like a DVR. Slide the tuner directly into a USB port on your computer, or a USB extension cable if the ports are too close together to accommodate the tuner. Avoid using a USB hub, as they usually don't draw enough power.  You can also install a TV tuner card into a spare PCI slot on your computer, though this is fairly difficult compared to plugging in a USB tuner. See this guide for details on installing PCI cards. An external USB TV tuner is much simpler to install than a TV tuner card, and is just as powerful. Some tuners come with a built-in antenna. Otherwise, use the coaxial connector to attach a cable from your antenna or cable box to your TV. If you wish to keep your cable box connected to your TV, but also want to connect it to your computer, you will need a coaxial cable splitter You may need to install software that came packaged with the tuner. Follow the instructions that came with the tuner to do so. Windows Media Center supports TV tuners. Start the TV tuner software and follow the instructions to scan for available channels. If you are using an antenna, the channels you receive will depend on signal strength and the power of your antenna.

Perdón is essentially the Spanish equivalent to the English "pardon" or "excuse me."   "perdón", pronounced "perr-donn" can be used in most minor, everyday incidents, such as accidentally bumping into someone or interrupting someone. Alternatively, you can say "perdóname", pronounced "perr-donn-ah-may", to give a more direct apology. The word disculpa, which translates as "apology" or "excuse"  and is pronounced as "dees-kool-pah" can be used to mean "forgive me." It is appropriate for minor incidents in which you need to excuse yourself. It can be used in the same situations as perdón.  When making an informal apology you would say "tú disculpa;" but when making a formal apology you would say "usted disculpe." When you say "tú disculpa" or "usted disculpe", you are literally saying "you forgive me", though it's an imperative.  As a result, "tú disculpa" and "usted disculpe" are listener-oriented apologies, because they make the listener the subject of the sentence. This structure, which is common in Spanish, places the emphasis on the listener's ability to forgive you rather than on your own feelings of regret. Alternatively, you can just say "'discúlpame", pronounced "dees-kool-pah-meh", which simply means "forgive me" or "excuse me" (informal).

Make sure to use equal parts baking soda and water.  Start by mixing 1 tablespoon of baking soda and 1 tablespoon of water with a spoon in a small bowl. Combine more if necessary. It's crucial to make sure the paste is thick enough to adhere to the rust. Using the rag, apply the paste and allow it stick to the rusted surface for a few hours or longer. Be sure to give the mixture enough time to set on the rust. Using steel wool, a wire brush, crumpled aluminum foil, or even a toothbrush, rigorously scrub the baking soda off of the tinware until there is none remaining. This process may need to be repeated a few times to get the entirety of the rust removed from the surface.
