Twitter is introducing emoji-based targeting, which means advertisers will be able to target users based on emojis they have used in a tweet. For example, if a user tweets a pizza emoji, that user could be served ads for pizza places.
Judy uses email, but she's having trouble forwarding email to someone else. Leo says to forward the mail exactly as it came, including attachments. If she tries to change it, she could end up messing it up. Using a computer at the library may be an issue as well. The browser may be older. It may also be a setting in the library's security settings to discourage that. Judy should try sending messages to herself and see if she can duplicate the issue.
Alex has been watching a lot of live videos on Facebook. He knows that a lot of these are used with mobile phones, but the sound is terrible. He's a musician and he wants to do live performances with Facebook Live. How can he improve the sound?
Dennis is going to be RVing full time and wants to know the best way to stay connected. Leo says that he can get a satellite add-on to his RV and many come with it built-in. He'll always have to aim it where he goes, though.
Jim is legally blind and uses an internet radio. He doesn't understand how to use it, though, and it buffers a lot. Leo says that Wi-Fi has a distance issue where the greater the distance, the weaker the system, and the slower the bandwidth. That's why Leo recommends plugging it directly into his router and he won't see nearly as much buffering. Leo recommends hardwire connections for any streaming device.
New website - RoomerTravel. It's like Stubhub for hotel rooms. Great for when you book a hotel room that you can't get refunded. You can list it here and offer it to another party. The site takes 15%, but at least you're getting something back. If you still want to hang on to your hotel, you can always call the hotel and ask to reschedule your booking for another date. Then later, if you still need to, you can cancel the reservation.
Betty can't log into the internet with her Mac. It says there are no plugins to do so. Leo says to check your router connection to see if your WiFi router is turned on. You can do that in the Apple's Network system preferences. If you can't see your access point, you're not connected to it. If it's connected, then look if the internet connection is available. If the WiFi router isn't working properly, it'll be connected, but it won't go anywhere. It'll just be a local address starting with 168. Try resetting your router.
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.
