But the datasets gathered in this way have been tiny — typically 20 people playing a handful of puzzles. Now one researcher has taken a different approach by mining the data from websites in which people can play games such as Sudoku. That's given him data on the way hundreds of players solve over 2000 puzzles, a vast increase over previous datasets and this has allowed him to plot the average time it takes to finish different puzzles. One way to assess the difficulty of Sudoku puzzle is in the complexity of each step required to solve it. But the new work suggests that another factor is important too — whether the steps are independent and so can be attempted in parallel or whether the steps are dependent and so must be tried in sequence, one after the other. A new model of this puzzle-solving process accurately reproduces the time it takes real humans to finish the problems and that makes it possible to accurately predict the difficulty of a puzzle in advance for the first time. It also opens the way for other studies of human problem solving using the vast datasets that have been collected over the web. Indeed work has already begun on the Sudoku-like puzzle game, Nurikabe."
First Oculus wasn't flush, and although Oculus may have had some hustle behind it, it may not have been enough. John Carmack, Oculus CTO, said via Twitter, 'I expect the FB deal will avoid several embarrassing scaling crisis for VR.' The headwear already famously suffered from a supply chain issue not long ago, which actually stopped it dead in its tracks. Next, in their official announcement of the Facebook deal, gaming was barely a blip on the radar. It wasn't until the very end that gaming was even mentioned, with the bulk of the post discussing 'culture' and driving virtual reality forward. There was little to indicate any big titles were coming for Oculus.
The fact is, Oculus needed help. Not technical assistance, but someone who could be their Sony, more or less. John Carmack says he has 'a deep respect for the technical scale that FB operates at. The cyberspace we want for VR will be at this scale.' Perhaps Facebook isn't the most popular choice, but they are the partner Oculus chose for their future says Swammer. 'Like Google purchasing Android in 2005, it all seems so strange right now [remember this story we discussed in 2009] — but we see how that turned out. If VR really is the next frontier, Facebook just staked their claim to a big slab of land in the heart of some virtual country they'll likely let us see someday — via Oculus.""
