In one sentence, describe what the following article is about: Use a match or lighter to heat up and sterilize the pin. Expose every bit of the pin to fire for several seconds to kill off any bacteria. Give the pin at least a minute to cool down. It should not be painfully hot when you use it to pop your pimple. Apply rubbing alcohol to the pin, to your hands, and to the zit. Be sure that everything involved in the procedure is sanitized with rubbing alcohol. You do not want to point the pin toward your face. Instead, you should hold it along your face, so that when you poke your pimple it won’t penetrate anything but the very tip of the pimple. Do not touch anything but the white part of the zit. Penetrating the red part of the pimple will cause scarring. Instead, run the pin through the very tip of the pimple, so that it goes through one end and out the other. The pin should have penetrated the length of the white tip. Pull the pin out, away from your face, so that it ruptures the white tip when you remove the pin from the pimple. Do not squeeze the white top itself. Instead, squeeze the perimeter of the pimple so that it pushes out the pus. Consider squeezing with a cotton swab to avoid doing additional damage to the skin. Use a cotton swab to rub the area down with alcohol and clean up bacteria. Apply a small amount of bacitracin ointment to the area.
Summary: Sterilize a pin with fire. Allow the pin to cool. Sterilize everything with rubbing alcohol. Hold the pin parallel to your face. Pierce the white tip of the zit. Pull up with the pin. Gently squeeze around the white top. Apply alcohol to the pimple.

In one sentence, describe what the following article is about: Avoid using USB hubs, as these may slow the process down significantly. You should see your USB drive appear on the desktop.  If your USB drive does not appear, see the Troubleshooting section below. A USB hub is an external device that allows you to plug multiple USB devices into a single USB port. It usually says how much free space is available below the USB drive on your desktop.  Most MP3s are about 3-5 MB in size or 1 MB per minute of audio.  Though this may vary depending on the quality of the file.  See the chart at the bottom of this article for a breakdown of how many songs can fit on a USB drive on average. Alternatively, you can right-click the USB drive below "Devices" in the Finder and click Get Info to see how much free space is available on the drive. If you're using iTunes for your music, you can quickly copy your music to a USB drive using the iTunes program. If you're not using iTunes, open the folder you keep your music in the Finder. You can transfer any of your songs or albums, but you won't be able to transfer playlists. You can hold ⌘ Command to select multiple files, or ⇧ Shift to select blocks of files. If you're using Finder, open the folder containing the music you want to transfer, then select the files and folders that you want to copy.  This is most likely the "Music" folder in the Finder. The files will begin transferring to the USB drive. The original files will not be removed.  If you're moving files from Finder, hold ⌥ Option while dragging them to the USB drive. This will leave the original file on your computer and create a copy on the USB drive. This isn't necessary if you're using iTunes. Alternatively, you can find the USB drive under "Devices" in the sidebar to the left in the Finder.  You can drag and drop files there as well. This may take a while if you are copying a lot of music files.  The amount of time it takes to transfer music depends on how much music you are transferring, and the speed of your computer and flash drive. After the transfer is complete, drag the USB drive to the Trash to safely unmount it. Alternatively, you can click the Eject icon next to the drive name in the Finder. After dragging the USB drive to the Trash, you can pull the drive out without worrying about corrupt data or damaging your Flash drive.
Summary:
Insert the USB drive into a USB port on your Mac. Check the amount of free space on the USB drive. Open iTunes or the Finder. Select the files in your iTunes library that you want to transfer. Drag the selected files to the USB icon on your desktop. Wait for the files to finish transferring. Drag the USB drive to the Trash. Remove the USB drive from the Mac.
