Any device that connects to the computer, such as a printer, scanner, monitor, keyboard or mouse.
Jonathan is thinking about digitizing home videos for his family and is wondering what form of media to put them on since his family uses iPods and tablets, etc. Leo says that in that case, putting them up on YouTube is a good idea and he can just keep the channel private. It also means that anyone can watch it. Making it available for download means that he'd have to format it for different versions depending on what device is being used. Leo says he won't have that issue with streaming.
Paul has a Bluetooth Speaker adapter, but his Mac tries to pair with it when he doesn't want it to. Leo says the only thing he can do is turn off Bluetooth on the Mac to prevent it from pairing. Leo doesn't know of any way to tell the Mac to not pair with a visible and previously paired Bluetooth device.
Donald upgraded his MacBook Pro to OS X Mavericks, but now he can't print. He has the printer connected to a PC, and is using Printer Sharing in Windows to print from the Mac. Leo says that Donald will have to delete and then re-add his printer.
Valerie wants to know if she can print something from her Android phone. Leo says she can, using Google Cloud Print. It uses the Internet and would let her print from anywhere in the world, but she would need a printer that supports it. She can also send it to Kinkos. Apple has AirPrint for the iPad and iPhone as well.
Mike has several mobile devices and would like just one charger that can handle all of them. Leo says that the Charlie Charger does that. It's a commercial charger that handles up to six phones. Unfortunately, with Charlie Charger the more devices he connects, the more the amperage drops.
Mike needs one that can devote a certain number of amps to each port. Scosche makes a 10 amp charger, giving two amps for each of the 5 ports, which should work great for Mike.
Nef's keyboard is suddenly typing strange letter and numbers. Leo says to be sure that the numlock or capslock isn't enabled. Keyboards can also get dirty and that could cause it. Keyboards are dirt cheap, and he can buy one and make sure it's just the keyboard that's wearing out. He can plug it in a different one, and if it works, he'll know his keyboard is going bad.
Bruce built his own Windows 8 rig recently. Leo says SSD drives would be great because Bruce doesn't have to wait for the drive to hunt and search for files. Bruce installed a RAM drive, something that Leo hasn't seen in awhile. RAM drives will always be fastest because it uses RAM to run the directory. Sounds like a machine that's as fast as he can get except that a RAM drive does have to push out the files and save them to the drive before shutting down. Bruce can always up the speed later with a GPU driven video card.
Trish's keyboard seems to randomly type letters and numbers when she's not touching it. Leo suspects the keyboard could have shorted out or the USB port it's plugged into is shorting out. She should try a different keyboard. If that doesn't fix it, then that would point to a different problem. Leo also suspects that the computer may still be paired to the wireless keyboard and her daughter is playing with it, causing the issue!
