Why aren't newer processors getting much faster?

Greg from Camarillo, CA

Episode 1099

Greg is looking to upgrade his processors and he's noticing they aren't that much faster. Leo says that processors aren't. They've found that faster processors get hotter and more unstable. So they've added more cores and more L2 cache to make them appear faster. We're pretty much at the limits of single core speeds. So Greg is wondering whether he should wait for it to die or replace it? Leo says just wait for it to die and keep his data backed up.

Are there private airspace rules governing drone use?

Episode 1100

Ellis from Marina Del Rey, CA
DJI Phantom Aerial UAV Drone Quadcopter for GoPro

Ellis wants to know if there are air rights established over buildings and residencies? Leo says that only if he is using drones for commercial purposes. He can only use it for private and personal use. Air rights? That's a lawyer question. Air rights do extend up, but the FAA regulates it. So the FAA is probably the best place to ask. The FAA is being very hard against commercial use of drones because of the explosion of drone usage.

Should I buy a Chromebook?

Episode 1100

Alex from Long Beach, CA
HP Chromebook

Alex is looking to get a Google Chromebook but people are trying to convince him to get a Windows laptop instead. Leo says that the fundamental difference between a Chromebook and a Windows laptop is that there's very little storage on a Chromebook -- everything is meant to be accessed from the cloud. The entire Chromebook is basically like using only the Google Chrome web browser on a Windows computer.

This week's gadget is the Selfy. It's a case for iPhone or Samsung Galaxy S5 that has a bluetooth remote shutter button. The shutter remote slides into the back of the case and you can slide it out anytime you want to take a selfy. They have accessories to fit into that slot including a tripod, bike mount, and helmet mount. It's great for parties and picnics if you take a lot of selfies.

Is BitLocker good enough for encryption?

Julian from Santa Barbara, CA

Episode 1099

Julian uses BitLocker to encrypt his laptop hard drive. Is that adequate? Leo says absolutely. It's more than sufficient. And with more than 12,000 laptops being lost and stolen every week at airports, it's a wise idea to encrypt his laptop hard drive when he's traveling. But remember -- BitLocker requires certificates, so he can't lose them. It's wise to back them up or he won't be able to decrypt his drive. He should make sure that he uses a very good, random password for the encryption as well.

Why are my TV speakers cutting out when I plug in my headphones?

Mark from Rhode Island

Episode 1098

Mark's mom won a new TV at work and he's been tasked with hooking it up. They also want to have the sound transmitted to a wireless headset for his father. But when he plugs it in, it turns off the speakers on the TV. Suggestions? Scott says that's a common problem and there may be a setting for audio submenus that will give the option to leave the internal speakers on. Scott says that since Mark uses a splitter, it's likely causing the TV to turn off the internal speakers.

What speakers should I get to mix my audio?

Episode 1098

JR from Detroit, MI
Cambridge Audio DAC Magic

JR is building a gaming system and he wants to add some great audio. What about the JBL speakers? The one's he's looking at are made in china and he's concerned about the build quality. Scott says that just because they're made in China doesn't mean they're no good. There's good and bad speakers from anywhere. Scott would recommend going with larger 8" woofers to go deeper in the bass. He also needs a digital audio converter.
