Could Color-Coded Maps Be the Answer to City Parking Problems?

Driving in a city isn't as simple as traveling from Point A to Point B. For many motorists, it's interpreting the parking signs, scoping out curb space, and avoiding tickets once they've already reached their destination that are the challenges. A new website aims to make the urban parking process a little easier to navigate: As City Lab reports, the new Curb Explorer tool from Coord uses a handy color-coded system to map out which San Francisco curbs are fair game for drivers and which are off limits.

You can navigate Coord's San Francisco street map like you would any other digital map. But instead of just a starting point and destination, Coord asks for more information about your parking needs, such as the day and time you plan to be arriving, the type of vehicle you're driving, and its uses. Based on those variables, the map highlights curbs in different colors that signify their parking availability. Red means no parking allowed, light blue indicates free parking, and dark blue means paid parking. Whether you're looking to park some place all day or for just a few minutes, you can input that information in the system and the map will update itself accordingly.

The new tool isn't just for private car owners: It's also for the employees of ride-hailing services like Uber and Lyft, who received over 75 percent of the lane-obstruction tickets issued by San Francisco police between April and June of 2017. Since November 2017, the city has rolled out dedicated pick-up and drop-off zones for such vehicles and now Coord makes it easy for drivers to find them.

Coord has a map for only one city at the moment, and even drivers in San Francisco may find it difficult to use. It's not an app; rather, it's a website that can be accessed through mobile, and the focus is just on parking rules rather than finding you a space. But if the technology is successful it may eventually work its way into other cities and even into established navigation apps.

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.
