The "sleep box" emits a very faint light between 6 a.m. and 7 a.m. -- when their daughters are expected to wake up. It doesn't show the time as that would stress her and disrupt her sleep, the Facebook Inc. chief executive officer said in an Instagram post on Saturday. "So far this has worked better than I expected and she can now sleep through the night," Zuckerberg said, adding that the device is already popular with his friends. "I'm putting this out there in case another entrepreneur wants to run with this and build sleep boxes for more people!" Also read click here. Not everyone was impressed. British singer Lily Allen took a jab at Facebook's effectiveness in curbing racist content, asking if there was an algorithm to make white supremacy go away. Last month, Facebook Inc. announced plans to ban content that references white nationalism and white separatism, taking a major step toward curbing racism and hate speech on the site.
