Laptop or desktop computers and any components within.
Dan has an aunt who lives a reclusive life and there are times she can't get up to open her door. Dan is wondering if there's a remote option that will allow her to open the door? Leo says sure, but she will also probably want a camera and monitor so she can see who's at the door before she opens it. That would require Wi-Fi, though. Schlage makes one that opens via Bluetooth. Kwikset was the first company to do this.
Steven wants to know what battery charger is best. He's seen one on SharperImage.com that looks pretty good. It's a Universal Battery Charger and it promises to regenerate batteries. Is it legit? Leo says that it's a bad idea to recharge alkaline batteries. He should get a rechargeable NIMH battery charger. Steven can check out theWirecutter.com for the best battery charger. He can get the charger with four batteries for around $21.
Chris wants to get an Apple Watch Series 3 and the iPhone X. He's heard rumors, however, that Apple is slowing down production, and he's wondering if he should avoid those products. Leo says to consider the source. For instance, Ming-Chi Quo is primarily an analyst and his job is more to decide if it's worth buying Apple stock over buying the iPhone. So far, there's been no confirmation of sales having softened due to supply. If anything, it's been quite the opposite, especially with the Apple Watch. Analysts and rumor guys are wrong more often than they are right.
Nikki bought a Chromebook and she thinks it's wonderful with no worries about security issues. However, the main account to open it crashes a lot and boots her back out. What can she do? Leo says she can "Powerwash" the Chromebook to get it back to factory default settings. She can do it before logging in. She can find out how to do this at support.google.com (here).
Alexa was everywhere at CES 2018. One place it makes sense is in the new First Alert Onelink Safe & Sound. The company says this is the first smoke and carbon monoxide (CO) alarm with a superior home speaker and Alexa built-in! A clever idea is that you're going to install smoke/CO detectors in a lot of rooms. Since the First Alert units need a speaker to call out the emergencies, why not install a top-notch speaker and Alexa, so you can also use the unit to communicate with Alexa. That way you can have music in every room, get the weather, etc. throughout the house.
Mary is a Luddite who hates the obsession with technology. She feels that she's being forced down the road of technology and she'd rather not, especially since she's been hacked twice in the last six weeks. Leo says that for what Mary uses a computer for, she doesn't need Windows at all. Mary would be better off with a Chromebook. It's far simpler and not hackable. It's a very simple and highly secure operating system that she can just directly connect via ethernet, and when she turns it on, it will go straight to the web browser.
Mike wants to wipe a hybrid SSD using Darik's Boot and Nuke (DBAN). Is that a good idea? Leo says that SSDs are written to differently than spinning drives, and it also uses a technique called "wear leveling," which writes sectors randomly. This makes it difficult to fully and securely wipe a drive to prevent it from being recovered. He can do it to erase a drive, but it won't really remove the data. That's why Leo recommends encryption. Using BitLocker on Windows, or some other technique to secure data with encryption.
Don has an Asus router and he has a USB in for connecting an external drive to it. Can he put a hub on it? Leo says sure. He can take up to 255 devices on the USB chain, but it may confuse the router, so he should look at the settings to see if it will support it.
Ken wants to know why he can't hear himself when he speaks with headphones? Leo says he'd need a mixer that can mix in. It's called Side Tone. It can be very distracting with Bluetooth on a phone though because of the latency. He would just end up getting confused by the echo.
