New Instagram features flag potentially offensive comments, allow you to quietly ‘restrict’ users

Instagram announced two new features today that it said are designed to combat online bullying.

In both cases, the Facebook-owned service seems to be trying to find ways to limit bad behavior without outright blocking posts or banning users.

“We can do more to prevent bullying from happening on Instagram, and we can do more to empower the targets of bullying to stand up for themselves,” wrote Instagram head Adam Mosseri in the announcement. “Today we’re announcing one new feature in both areas. These tools are grounded in a deep understanding of how people bully each other and how they respond to bullying on Instagram, but they’re only two steps on a longer path.”

The first feature is supposed to use artificial intelligence to flag comments that “may be considered offensive.” In those cases, users are asked, “Are you sure you want to post this?” and then given the option button to “undo” their comment before it posts.

This might seem like a relatively tame response, [...]  read more

Why We See the Colors of Faces Differently Than Other Things

As set-ups go for studying how people see colors, this one isn’t even the weirdest: a room full of assorted objects, like Lego bricks, strawberries, and ping-pong balls. Bring people into the room and give them a computer. Tell them to use a mouse to adjust the color of a big spot on the screen, like a color-picker tool in reverse.

Then a researcher would point at one of the objects and say, basically, make that spot on the computer be the same color. Easy, right? The yellow Lego, the red strawberry, the white ping-pong ball. That’s what color vision is for after all. It uses the photoreceptors at the back of your eyeballs and a lot of computational neurocircuitry to come up with a representation of the wavelengths of light that a given surface reflects. Good information to have.

Except … well, you knew there was going to be a trick here, and in fact there are two. First, under white light, sure, no problem. The human brain is set up to interpret the way things reflect [...]  read more

AMD Radeon RX 5700 vs RX 5700 XT: what’s the best AMD GPU for you?

Right now, we’re having a tough time thinking of a better time to buy a new graphics card, thanks in large part to the new Nvidia Super RTX graphics cards, and of course, AMD Navi. Why’s that? Well, before the AMD Radeon RX 5700 and RX 5700 XT, we’ve never seen graphics cards this affordable that can provide such amazing performance in this price range. 

But, no matter how awesome these graphics cards are, it can be hard to decide once and for all which AMD graphics card is best for you – especially when they’re priced so closely together. 

Luckily, here at TechRadar we’ve spent an inordinate amount of time obsessing over the best graphics card, so we can help you decide whether to go with the AMD Radeon RX 5700 XT or the Radeon RX 5700.

The sinkhole that saved the internet

It was late afternoon on May 12, 2017. Two exhausted security researchers could barely unpack the events of what had just happened.

Marcus Hutchins and Jamie Hankins, who were working from their homes in the U.K. for Los Angeles-based cybersecurity company Kryptos Logic, had just stopped a global cyberattack dead in its tracks. Hours earlier, WannaCry ransomware began to spread like wildfire, encrypting systems and crippling businesses and transport hubs across Europe. It was the first time in a decade a computer worm began attacking computers on a massive scale. The U.K.’s National Health Service (NHS) was one of the biggest organizations hit, forcing doctors to turn patients away and emergency rooms to close.

Hours after the disruption began to break on broadcast news networks, Hutchins — who at the time was only known by his online handle @MalwareTech — became an “accidental hero” for inadvertently stopping the cyberattack.

The internet, still reeling from the damage, had gotten [...]  read more
