David's landlady has wifi but she doesn't want to improve the signal so he can get a better connection. Leo says you can get a WiFi antenna to improve your signal,but if you can convince your landlady to put the access point in a better location, that would be the ticket. Check out RadioLabs.com for tips on which directional antenna to buy to get a better signal. You could also offer to buy her a newer 802.11 AC router. Leo likes the Asus C3200. It goes a long way.
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.
Tony wants to know how to check to be sure the ISO of open source software is legit. Leo says that an ISO is found to be legit by signing. A hash has to be generated in order to provide proof of a legitimate ISO. If the ISO has changed, then the hash would be modified. There's also a signing key, which is based on GPG encryption. It has to be authenticated by the developers of the software.
Ron has the Tiny Hardware Firewall, which he likes. Once he's connected to the VPN inside of it, what does the firewall do, though? Leo says that the firewall is the first level of protection. It acts as a router and is the attack surface, not the computer. A router is a dumb device that doesn't know what the attack is and ignores it, unless there's a security flaw inside the system. Like a router at home, the Tiny Hardware Firewall gives a little extra protection, though.
Twitter security officials have admitted that the social media site was hacked this week, exposing the passwords of over 32 million twitter accounts. Though hackers posted the passwords online, officials say that they are confident no other information was obtained.
Leo says that if you are a Twitter user, you may want to change your password, and even better, use a password vault to generate it.

Scott lives in a retirement community and they are creating a community TV station. He has a huge budget to buy equipment. Leo says that he doesn't have to spend tens of thousands of dollars on equipment anymore. Leo uses consumer grade Canon VIXIA camcorders that cost $300, and tripods should only cost a few hundred.
Chris is looking at the Tiny Hardware Firewall. He thinks it's a great idea, but what VPN client should he use? TOR? Leo says that TOR and VPN are different things. VPN or "virtual private networks" are tunnels bored through the internet, but TOR encrypts it. It is great and Leo uses it when he travels or is using a public Wi-Fi access point. It just fits in his pocket, too. He should be careful when he's joining a public hotspot. He'll get most of the benefits from a VPN, though, if he just surfs to sites using https.
Ralph has been victim of the transition from Verizon to Frontier and he's looking for live TV alternatives. What about cable TV over the internet like Vstream? Leo says it depends on the source of the channels they bring. Many are either illegal, or foreign language TV. He could end up with soccer from Ecuador. It's not going to be ABC, ESPN or his local news. It really comes down to content. He'd really be better off going with Roku and then add things like Netflix, HBO, etc.
Dan's daughter is graduating from high school on Friday and he wants to be able to broadcast the graduation ceremonies to family all over the world. How can he do it and have great audio? Leo says that everyone has gotten into live video streaming with Periscope, Meerkat, and Facebook Live. The benefit of Facebook is that they'll even save it to his account so that people can watch it any time.
