Laptop or desktop computers and any components within.
Joe has an old Vista computer that he uses mostly for syncing an old Windows Phone PDA. Joe would like to take that laptop and put Linux on it with an SSD. Leo says that Linux is a good idea, but that Vista laptop is probably not fast enough to get any great benefit from an SSD. But he should definitely install Linux on it. Leo likes XUbuntu and LUbuntu, which is designed to run on the older hardware.
Daniel is looking to get a MacBook Pro for video and music editing. Leo says that Macs are excellent for that, and Final Cut is a popular editing tool. But for Leo, the Touch Bar doesn't really work and is an added expense for no good reason. The lower end MacBook Pro isn't really power enough for editing a feature, though.
Tom wants to know if solar power is affordable. Leo says they use Solar City's Power Purchase agreement and it's slightly less expensive than the local power company. Solar power isn't all that efficient, but it's getting better and more affordable over time.
Scott wants to know if he can take the hard drive out of an old computer and then put it into a new one. Leo says yes, but he should only use it as a data drive. He could probably put it in an external USB enclosure so he can plug it in when he needs to. He could install it as a secondary hard drive as well. If he wants to use software from that hard drive, that's a lot more problematic due to registry issues. He may be able to dual boot from the older driver, but the device drivers won't work. So he'll have to work around that and use a boot manager.
Al has an old HP laptop that he got from a friend. It's a little old for what he wants to do with it, so what computer can he replace it with? Leo says to download Ubuntu and install it on that old computer. It's Linux, which means it's free and secure. It's designed to run on older systems as well. It'll breathe new life into that old laptop.
David wants to be able to control his lights with his mobile phone. Leo says he can with so called "smart lightbulbs" that are part of the Internet of Things. But because they connect to his network, they have a huge vulnerability that allows hackers to get into his network through the light bulb.
David loves his Bose Quiet Comfort headphones. Can he get a Bluetooth adapter for it? Leo says there are Bluetooth adapters, but it may not sound as good as he would want it to. There is a new standard coming called APT-X, which is the successor to A2DP and it promises better audio. But both ends have to be APT-X compliant.
Tristen wants to know how to backup his computer so that he has a copy locally. Leo says in the old days, we would divide backup into online, nearline, and offline backups. Online backup would be a hard drive connected to the computer that is synchronizing with data directories. So he'd have a copy on the computer and on the external drive. Nearline backup would be if the drive were put up on a shelf, and disconnected from the computer. Offline backup would be off in the cloud or at a different location entirely. It's best to use all three methods and keep multiple copies.
Martinio can't see his external hard drive on his computer when he boots up. What software can he use to fix it? Leo says first he'll have to be able to see the drive to fix it. If he can't see it, then there's a hardware issue. It's a very expensive proposition to get the data off. DriveSavers will be able to do it, but it's very expensive.
4Moms has a high tech stroller called The Moxie Stroller. It has a power generator in the wheel to charge your mobile device, plus an LCD dashboard that displays speed, distance, temperature and calories burned. It has headlights and tail-lights. The company says it's compatible with their 4Moms self installing car seat we showed last year, and several other models. It's suitable for a child from birth to 55 lb and offers a full coverage canopy with pop out shade and UPF 30 protection.
