The Pope's Swiss Guards Are Now Outfitted in 3D-Printed Helmets

The Popemobile isn't the only innovative piece of gear used by the Pope and his posse. Though they still look traditional, the outfits worn by the Swiss Guard now include a high-tech piece of headwear designed by the 3D-printing design team at HP, Fast Company reports.

Members of the Swiss Guard, the Vatican's private army, wore the same helmet for more than 500 years. The steel hat is branded with the crest of Pope Julius II (the "mercenary pope" and the guard's founder) and embellished with a red feathered crest for special events.

Though it made for an iconic look, the original helmet had some practical issues. After baking in the Sun for hours, the metal would heat up and burn the guard's heads. Steel also isn't the most comfortable material to be wearing on your head all day, and because it rusts so easily, it doesn't make sense to wear it in the rain.

The updated helmets from HP solve these problems while maintaining the style of the old headgear. They're made from PA-12 plastic, which means they're lighter and resistant to UV rays. They're also water-resistant and don't need to be polished constantly to prevent rusting.

The hats are even more affordable than their more traditional predecessors. It costs $1000 and takes 14 hours to 3D-print each PA-12 helmet, while it took $2000 and 100 hours to forge a single steel one.

What's the Difference Between a Router and a Modem?

Despite using it every day, the internet is still a mystery to many of its users. If asked to explain how your home internet connection works, you may start with your router and modem. Both devices are essential to setting up a wireless network, but they serve distinct functions. Here are the major differences between the two pieces of hardware that make home internet run.

What is a Modem?

The modem is your home's gateway to the World Wide Web. It's often a skinny box with a row of LED icons on the front that tell you if it's on and connected to the internet. The name is short for modulator-demodulator—a phrase left over from the days of dial-up when modems worked by modulating telephone signals into frequencies that could send digital information.

Today, most modems use broadband connections like cable or satellite to transmit data. There are different types of modems built to fit different connections. If your internet service provider (ISP) uses cable or fiber internet, you'll need to plug a cable into the back of your modem, and if you still use a digital subscriber line (DSL), you'll have to plug in a phone line.

What is a Router?

You can connect to the internet with just a modem as long as you don't mind plugging your device directly into the Ethernet port. But if you want to provide internet to all the laptops, desktops, and smartphones in your home at the same time, you'll need a router.

Routers usually lie flat and have antennas sticking out of them. The router hooks up to your modem via an Ethernet cable and acts as a conduit between the direct internet and your home network. After connecting your devices, the router "routes" your modem's networking traffic their way, either through Ethernet wires or wirelessly through Wi-Fi (that's what the antennas are for). The router also works in the other direction by routing data sent from your computer back to the web.

Why Knowing the Difference Matters

When they've been sitting in the same spot in your home for years, it's easy to think of your router and modem as basically the same thing. But it's worth knowing the difference—especially if you care about improving your internet connection. Now that you know the router is what directs Wi-Fi signals, you can boost your home network by placing it in a central location away from electronic appliances. And as long as it doesn't interfere with the router, feel free to hide your modem behind a houseplant.

Hackers Used Facebook Quizzes to Steal Data from 60,000 Users

It’s been a tumultuous few months for Facebook. A data breach in fall 2018 exposed information about 30 million of its users to hackers. Only a few months later, the company was also criticized for paying individuals to voluntarily install an app that collected information about their smartphone habits. Now, it’s dealing with concerns that some of the quizzes available on the platform have been used to collect data from unsuspecting users.

According to CNN, the scheme is detailed in a lawsuit Facebook filed in California last week against developers Andrey Gorbachov and Gleb Sluchevsky. The defendants, who are based in Kiev, Ukraine, allegedly created quizzes like, “Do you have royal blood?” or “What does your eye color say about you?” as a way to access private user data. When Facebook users interacted with these tests, they were prompted to install browser extensions that allowed the alleged hackers to pose as those users, collecting information as well as taking control of their browsers. The improperly obtained information consisted of names, ages, and friend lists, which hackers then used for targeted advertising that they injected into users' feeds.

It’s possible the breach also resulted in the publication of 81,000 private messages in 2018, which was initially blamed on unspecified malware browser extensions that have not yet been publicly identified. Facebook has yet to confirm the two incidents are related, however.

Facebook said that the primary targets of the operation were Russian- and Ukrainian-speaking users, with 60,000 browsers compromised.

This isn't the only time Facebook quizzes have been tied to data breaches. Last year’s Cambridge Analytica controversy revealed that the firm used quizzes and questionnaires on Facebook to surreptitiously compile data on millions of users.

So what should you do about it? Online security experts caution against third-party apps that are accessed through Facebook. If you’re concerned about utilities that you installed without much thought, you can see a list by clicking on Settings, then the Apps link on the left menu. If you don’t recognize an app, it’s best to delete it.
