Here are 5 things you should know.
1. Most scam calls scan audio for a deadline, so the best way to end scam calls is actually to pick up and not say anything. If it’s quiet, the system will mark you dead and delete you. If it hears a dial tone or goes to voicemail, it will call again later.
2. Roombas/cleaning robots can have trouble on dark carpets, due to the robot’s cliff sensors interpreting it as the edge of a surface (like a stair).

Despite what they say, if you don’t have stairs and/or if you have one of the electronic gates, you can cover the sensors to let it clean on the dark carpet.
3. You can permanently close the right pane when you open a PDF using Adobe Reader DC.
Go to Edit > Preferences > Documents, and then select Remember the current state of Tools pane.
Open a PDF document in Reader DC, and then collapse the Tools pane. Click OK. Relaunch Acrobat Reader DC.
Voila! Acrobat Reader now remembers the state of your Tools pane. If it was collapsed (or expanded) during the last launch, it remains collapsed (or expanded) when you launch again.
4. Glyphosate increases cancer risk by 41%, study says.

5. You can force the sign-up pages for public wifi by going to http://http://fixwifi.it/
Sometimes when you connect to public wifi, you get No internet connection error and that is because some public wifi like airports and Starbucks requires login info to be filled out. Many times due to the default browsers in windows or mac you might not get that sign-up page. Without doing any further debugging you can simply go to Fix your Wifi and it will force the sign-up page to load.
