Tom is wondering if it's necessary for him to have a VPN (Virtual Private Network). Leo says if he uses Wi-Fi in public, or he uses networks while traveling, he's somewhat vulnerable because he's on a public network that bad guys can get into. They can't necessarily spy on him, but they could trick him by putting up fake access points. A VPN sets up a connection between his computer on a public access network and a computer somewhere else run by a trusted party. All the data transferred over a VPN is encrypted so it isn't visible by anyone else on that network.
Brett has a Dell computer and wants to know if there's an open source program that can speed up his computer like Dell does with Click to Fix? Leo says that Dell doesn't share their secrets and Leo doesn't think that it's safe to use a third party open source option for this. Dell's Click to Fix knows its own hardware and as such, can do a targeted fix. Open source stuff can't do that and can be overly aggressive and cause more problems than it fixes.
Jonathan knows someone who lost an iPad in the snow and found it months later. It actually turned on! Leo says Jonathan is incredibly lucky. Leo says to make sure it's fully dried out before turning it on again. He should stick it in a bowl of rice and let it sit for a week. This will draw out all the moisture. There may also be corrosion.
David updated his mobile phone and he's lost a lot of apps. Leo says that if he opens the Google Play store, there's a menu item for "My Apps." It'll show what's on his phone and what isn't. If he presses and holds the first app he wants, he can then select all the apps he wants and it'll reinstall them.
Google announced many improvements to its "machine learning" or artificial intelligence capabilities with Google Assistant. Google has already been learning about its users preferences and delivering relevant information through Google Now.
Steve is having trouble recovering his password in Gmail. Leo says that password recovery is the number one way to get an email account hacked, so Google makes it really difficult to recover. That's why Leo recommends using 2nd factor authentication so that he can get a text with a code to recover it easily and securely. If he hasn't done that, he'll have to jump through a few hoops including telling Google about a recent email he sent. If he can't do that, he may be out of luck short of contacting Google.
Ian heard that Apple has stopped support for Quicktime for Windows. He's uninstalled it, but there are programs like Adobe Premiere and Hyper Studio that depend on it. Leo says that there may be an update through the programs that will support other options. If there isn't, there should be soon. In the meantime, Ian should make sure that his browser can't launch Quicktime. He can go into the settings and disable it.
Saying that the federal government has demanded personal data of their customers over 2500 times this year, Microsoft has sued the federal government demanding that the court rule on how the company must provide the information. According to the complaint, Microsoft is not allowed to tell their customers of the action, nor is there any expiration on the demands, effectively tying up the company forever. Microsoft is asking the court to rule and provide a level of transparency, and to act as a hedge against an overreaching government.
Jay wants to get rid of cookies and prevent them from being saved on his computer. Leo says that cookies are supposed to be used to save data when visiting a website so that when he returns to it, he won't have to reload or relogin. Not only that, but it gives him ads based on his interests. He can turn off 3rd party cookies, though, if he wants.
