    Google-Backed SSD Endurance Research Shows MLC Flash As Reliable As SLC
    MojoKid writes: Even for mainstream users, it's easy to feel the differences between using a PC that has an OS installed on a solid state drive versus a mechanical hard drive. Also, with SSD pricing where it is right now, it's also easy to justify including one in a new configuration for the speed boost. And there's obvious benefit in the enterprise and data center for both performance and durability. As you might expect, Google has chewed through a healthy pile of SSDs in its data centers over the years and the company appears to have been one of the first to deploy SSDs in production at scale. New research results Google is sharing via a joint research project now encompasses SSD use over a six year span at one of Google's data centers. Looking over the results led to some expected and unexpected findings. One of the biggest discoveries is that SLC-based SSDs are not necessarily more reliable than MLC-based drives. This is surprising, as SLC SSDs carry a price premium with the promise of higher durability (specifically in write operations) as one of their selling points. It will come as no surprise that there are trade-offs of both SSDs and mechanical drives, but ultimately, the benefits SSDs offer often far outweigh the benefits of mechanical HDDs.

    People Will Follow a Robot In an Emergency - Even If It's Wrong
    An anonymous reader writes: Imagine a future where instead of siting through fire alarms with your fingers in your ears, a robot come comes to greet you and guide you out of the building. Researchers at Georgia Tech created an emergency guidance robot and then looked at whether or not people would follow the robot during an emergency. 'The research was designed to determine whether or not building occupants would trust a robot designed to help them evacuate a high-rise in case of fire or other emergency. But the researchers were surprised to find that the test subjects followed the robot's instructions – even when the machine's behavior should not have inspired trust.' The robot first guided people to a meeting room. In some conditions the robot broke along the way to the meeting room. Then, unbeknownst to the subjects, the researchers filled the hallway with smoke and set off the fire alarms. Given the option of going out the way they came or following the robot down an unknown hall, nearly all followed the robot.

    Microcasting Color TV By Abusing a Wi-Fi Chip
    szczys writes: The NTSC standard has effectively been replaced by newer digital standards, but most televisions still work with these signals. This can be done through a composite video connection, but more fun is to broadcast video directly to your television's analog tuner. This is what cnlohr has been working on, using a lowly ESP8266 module to generate and transmit the color TV signal. This board is a $3 Wi-Fi module. But the chip itself has a number of other powerful peripheral features, including I2S and DMA. This hardware makes it possible to push the TV broadcast out using hardware, taking up only about 10% of processor time. Even more impressive, cnlohr didn't want to recompile and flash (which is a relatively slow process) during prototyping so he used a web worker to implement browser-based development through the chip's Wi-Fi connection. Speaking of chip-abuse in the interest of hyperlocal signal propagation, reader fulldecent writes to point out a project on GitHub that "allows transmission of radio signals from a computer that is otherwise air gapped. Right now this could be useful for playing a quick tune or for pranks. But there are more nefarious uses as this could also be used to exfiltrate information from secure networks."
