Laptop or desktop computers and any components within.
Glenda is looking for a good color printer. Leo says that Epson's EcoTank (a sponsor of the radio show & TWiT) InkJet is a great one. The ET2760 is a great choice and also offers automated two-sided printing. It'll also give you a bigger ink reserve tank. And the EcoTanks are great because they give you all the ink you need in the box.
Todd has built a WiFi based security system and he's been able to get reception at a distance of a half mile. Leo says that's incredible. But if you have an unobstructed view line of sight, it may happen. But any kind of metal in between can cause that range to lower, or the bandwidth quality to drop, especially when transmitting video. Leo says you could try moving the stations around to get a better line of sight connection.
Mark's Mac Air is slowing down and he wants to know if there's an app like SpinRite that can run them. Leo says that sold state drives (SSDs) use TRIM, or wear leveling to keep your SSD in good shape. It doesn't need to be defragged directly. But it will trigger the controller to run the TRIM utility. Search for TRIM in macOS. But it should happen automatically. If your OS is older though, you may need a third-party app to do it.
TRIMFORCE Enable is the command you can use in the terminal. That could speed it up.
Grant is interested in a Virtual Reality desktop experience. Microsoft was looking to push that idea with their Hololens for VR, but Leo believes they are backing off on that idea as people believe there's still a ways to go with VR. Having to wear VR goggles for so long can potentially make you sick and that you can't see the world around you. Augmented Reality, or Mixed Reality as Microsoft is calling it, is a possible fix around Microsoft is pushing since it overlays information onto your display while enabling you to still see the world around you.
Sam Abuelsamid came onto the show to talk about exciting ways car manufacturers are using cameras in new cars. He also mentions how, since 2016, it's been mandatory for manufacturers to include backup cameras in their vehicles.
Lenaea is looking for a new PC to use with two 60Hz televisions. Leo doesn't recommend using a television as a computer monitor, as TVs aren't generally designed to be used with computers. It can be hard sometimes to read font or text on televisions if you're reading a news article or post. But with technology becoming more advanced within televisions, you can do it if you choose.
Twistedmister in the chat found an article about Chrome Subsampling that would help with the television.
Jooki is a music player that lets kids play parent-approved music and stories from Spotify & more. It comes with 5 characters (like fox, whale, etc.) that link to various playlists. When a kid pop one of them in the center ring of the Jooki, it starts to play the music, story, etc., that has been uploaded to that character. The company says there's 8-hour of battery life (there's no screen to suck up battery juice), which means very long playtime outdoors or on the go. There's a small amount of onboard memory but there's an SD card slot to add more.
Mike wants to know if he can use more than one monitor on his computer. Leo says that most modern-day computers do support multiple monitors and both Windows and macOS support it natively. But the computer has to have more than one display port or HDMI port to do it. Most do out of the box these days.
George has an iMac, but it won't let him upgrade to Catalina. Leo says to go to the Apple Menu and look under System Preferences. There's an update feature there, so select the gear. It'll run the update check. He can also look for the compatibility checker here - https://www.apple.com/macos/catalina/.
Mike wants to know if he should buy a MacBook Pro instead of his old MacBook Air. Or should he go to a Dell XPS laptop? Leo says it depends on what Mike is going to use his laptop for. Leo says that a MacBook Air is a great choice for doing Mike's business. But so is the MacBook Pro. Leo would recommend the 13" model for better battery life. Leo also says that the new HP Spectre 360 will be coming out in a few weeks and it'll offer all-day battery life. Thin and light. It also has the 10th-generation Intel processor.
