Are You Really Muted? Mute Buttons in Video Conferencing Apps

By -

 

Researchers from the University of Wisconsin and the University of Chicago have found in a research that muting popular video calling apps does not actually mute the microphone, continuing to record from it. 

According to the researchers, the mute buttons in the apps do not deactivate the microphone, but only mute it for other users. The worst part is that it's hard to know when an app isn't analyzing sound, since the microphone and camera on indicator doesn't work with all video calling apps. 

Zoom, Microsoft Teams/Skype, Cisco Webex, Google Meet, Jitsi Meet and Discord are on the list of users who like to eavesdrop. Every minute they send packets with your audio data to their servers❗️

To My Porn-Watching Dad, From Your Daughter

By -
Dear Dad, I want to let you know first of all that I love you and forgive you for what this has done in my life. I also wanted to let you know exactly what your porn use has done to my life. You may think that this effects only you, or even your and mom’s relationships. But it has had a profound impact on me and all of my siblings as well. I found your porn on the computer somewhere around the age of 12 or so, just when I was starting to become a young woman. First of all, it seemed very hypocritical to me that you were trying to teach me the value of what to let into my mind in terms of movies, yet here you were entertaining your mind with this junk on a regular basis. Your talks to me about being careful with what I watched meant virtually nothing. Because of pornography, I was aware that mom was not the only woman you were looking at. I became acutely aware of your wandering eye when we were out and about. This taught me that all men have a wandering eye and can’t be t...

The Northern Regional Director of Education, Mohammed Haroon Cambodia has confirmed government will be paying a staggering GHC400,000 as judgment debt to a private citizen in order to stop the auctioning of vehicles belonging to the Ghana Senior High School in Tamale. Government is offering the bailout following a chronic transport difficulty that has hit the school for the last two years after a court order impounded the only bus for students and a brand new official pickup vehicle.
