How to Block Porn on Any Device. For Free.

‍

The Internet is full of pornography.

‍

Anyone who has spent any time searching for anything on the unfiltered Internet knows explicit content is often just a few accidental clicks away. In the Childhood 2.0 documentary, I used the illustration of a coffee table. Thinking analog for a moment, imagine your child waking up daily with four magazines on a coffee table. Three are fine and one is pornographic and you just hope they make the right choice daily. That's the unfiltered internet today.

It’s for this reason caring adults need to have a basic understanding of how the domain name system works. Through this understanding, parents can block most pornography. For free!

Understanding the Domain Name System (DNS)


In the Internet Hall of Fame, we find Paul Mockapetris, who expanded the Internet beyond its academic origins by inventing the Domain Name System (DNS) in 1983.

Think of DNS as the digital phonebook for the Internet. Humans look for information by typing in words like “protect young eyes” (also referred to as a “domain name”) while computers use IP addresses (a series of numbers) to communicate, like 123.45.678. The DNS translates the words into numbers so that the Internet can show humans what they’re looking for.

Yes, every single time you type words into Google, there’s an entire translation system that’s attempting to take human-speak and turn it into computer-speak and then vice-versa.

And located all around the world are DNS servers that house databases of public IP addresses (because not all websites are public - like the dark web, your banking information, and your Disney account) and their associated domain names. The DNS services use that information to “resolve” or translate our human Google searches into something understood by computers.

Super Age: Microplastics—tiny plastic particles between 1 nanometer (nm) and 5 millimeters (mm) in size—have infiltrated our environment, including the food we consume daily.

Microplastics—tiny plastic particles between 1 nanometer (nm) and 5 millimeters (mm) in size—have infiltrated our environment, including the food we consume daily. While research into their long-term health effects is ongoing, and there are no targets for “safe” amounts of microplastics in our bodies, a 2024 study in the New England Journal of Medicine (NEJM) linked the presence of microplastics in arterial plaque to a significantly higher risk of cardiovascular events. Researchers have also connected micro- and nanoplastic exposure to inflammation , immune dysregulation , and metabolic disruptions . Still, we’re early in understanding what these exposures mean for human health. There are no established safety thresholds for microplastics in the body. But the absence of a limit doesn’t mean the absence of risk. To help readers understand where exposure might be coming from, we’ve ranked common foods and beverages from the lowest to highest measured microplastic load per serving. But p...

Very Well Mind: What Does a Messy Room Say About Your Personality?

  What Does a Messy Room Say About Your Personality? Is your mental health or personality the reason for the mess? Organization is big business these days. From books to seminars to organizational systems, everyone seems to want to find some way to perfectly arrange every aspect of their lives. Have you ever walked into a messy house (or contemplated your cluttered abode) and thought, "Why?" There are many reasons a person might not clean their house, including mental health, personality, and stress. Do you ever dream of living in the perfectly clean and organized rooms of a home décor catalog? Or would you rather spend your time in a home cluttered with objects, souvenirs, books, art, and items that make up your daily life? Both of these questions are another way to ask: what causes someone to not clean their house? For some people, a tidy home can be soothing, an orderly retreat in an often disorderly world. For others, such environments can be sterile, bland, and uninspiri...
