Laptop or desktop computers and any components within.
Andy is thinking about getting into day trading. What does Leo think? Leo says to read FLASHBOYS. Trading is now an automated, high volume business, and trades are happening in milliseconds, often before anyone at the NYSE knows what's happening. That is the competition. And it's really easy to lose a shirt in day trading, as you get leveraged buying stock on margin.
He'll need a very powerful computer, but any laptop can do basic day trading. It's quite an investment. He'll also need software and a subscription to wall street's feed.
Chris has an Apple Watch Series 3, and thinking of moving up to the Series 4. But it's $800. Worth it? Leo says that he's stopped buying the higher end models because he's going to be getting a new model next year. So he gets the cheapest one, knowing he'll trade in next year. It's just as nice looking and durable too.
Steve just found out his IRIS home hub service is being discontinued at the end of March. So what should he get to replace it? Leo says that the wide variety of competing standards has created a kind of house of cards where one platform goes out of business, leaving users to look elsewhere. If there was a standard protocol, that wouldn't happen. Leo says that Samsung SmartThings may work with his existing products because they use Zigbee and Z-Wave protocols. Google is a big player but can tire and kill off services. Leo recommends going with Samsung SmartThings.
The Giz Wiz is at the Toy Fair where he saw Oobleck! What The Heck Is It? Is it a liquid? Is it a solid? Yes, it is. It's both. Oobleck is a non-Newtonian fluid, meaning it acts as both a liquid and a solid. You can pound your hand on it (as you'll see on this week's show) and your fist will just bounce off it. And after you do that you can scoop it and roll it into a ball (as a solid), and then it can even ooze out of your hand (like a liquid)! Comes in a variety of colors. It's said to contain only non-toxic and washable materials.
Sam is still using an old Windows XP machine. Leo says that as long as you're not working online, and it's still reliable, it's still OK to use. But can he buy a new computer and still move his old data? Leo says he'd need an interface adapter to connect the IDE drive into a USB drive. Leo recommends the Universal Drive adapter.
Dan is shopping for a MacBook Air for his son's trip to China. but when you add more RAM, it's more than the MacBook Pro. So should he get a MacBook Pro instead? The MacBook Pro will have a faster processor and more storage, plus the size is about the same. So maybe the MacBook Pro will be a better option. Especially since it offers more storage for $500 less. It has the older butterfly keyboard, however, which could cause problems if eating while working. SO make sure to buy AppleCare plus.
Backblaze, a backup company, attempts to determine the reliability of Solid-State Drives in their recent article. SSDs are generally faster than spinning drives, but some people aren't too confident in the endurance of their memory cells.
Jerry wants to know if people can use their Apple Watch to cheat at trivia at the local bar. Leo says absolutely. It's why you can't bring a smartwatch or a phone into a college classroom.
Fred has a 2008 MacPro Cheesegrater, and he doesn't want to replace it. But it's having kernel panics. What can he do? Leo says a kernel panic is Apple's version of the blue screen of death. And it usually means it has a driver issue or a hardware issue. And sometimes, the first line of the panic will tell you something useful. Bad memory is a common cause of them. Power supply failing is an indicator. Try swapping out single RAM cards. That can tell Fred which RAM is acting up. He could just get one of the latest MacMini's and get a Thunderbolt 3 connection.
Kevin wants to know how he can update the firmware on his old TIVo Roamio. Is there a way to put a new OS on it, like KODI? Leo says that would be difficult, it was designed to be a streaming media player. TIVOCommunity.com is a good place to go to see if anyone is doing that. Another good source is WeakKnees.com since they resell hardware.
