Episode 1716

Jim from Hart, Michigan

Jim has a solution for remembering passwords. He uses a date mixed with his name and an @ symbol.

Windows 7

Episode 1713

Bob from Brea, CA

Bob wants to know if he can use his old Samsung Netbook on the Internet. Leo says that Netbooks were woefully slow and underpowered and didn't wear well. It also lowered the expectation of what we should pay for a laptop. It also was driven by Windows 7, which has stopped being supported by Microsoft, and as such, might be a security issue. At some point, a hack may be the risk. Leo says that Bob could upgrade it to Windows 10, or he could even run Linux on it. PopOS is one.

Or better yet, upgrade to a new Chromebook.
