LinkedIn Ran Social Experiments on 20 Million Users Over Five Years LinkedIn ran experiments on more than 20 million users over five years that, while intended to improve how the platform worked for members, could have affected some people’s livelihoods, according to a new study. In experiments conducted around the world from 2015 to 2019, Linkedin randomly varied the proportion of weak and strong contacts suggested by its “People You May Know” algorithm — the company’s automated system for recommending new connections to its users. Researchers at LinkedIn, M.I.T., Stanford and Harvard Business School later analyzed aggregate data from the tests in a study published this month in the journal Science. LinkedIn’s algorithmic experiments may come as a surprise to millions of people because the company did not inform users that the tests were underway. Tech giants like LinkedIn, the world’s largest professional network, routinely run large-scale experiments in which the...
10 Reasons Why Pcs Crash U Must Know Fatal error: the system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications." You have just been struck by the Blue Screen of Death. Anyone who uses Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening? 1 Hardware conflict The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device. For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself. If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When th...
How I made $3,300 on a short niche philosophy book The Based Deleuze project is now officially complete, so it’s time to do some final accounting. Here I will review the financials, the labor/time costs, and the main lessons learned. Based Deleuze was conceived and executed as a hard test . In research design, a hard test is a study that’s unlikely to find evidence for a hypothesis. If you use a hard test and you still get the results predicted by your hypothesis, then you can be extra confident in your hypothesis. As soon as I quit academia, my top priority was to generate reliable data about how much I could earn for my research and teaching on the open market. So for my first book, I strategically chose to do something as fringe/weird/unmarketable as possible, as quickly as possible. If I could get half-decent results, then I could confidently make future plans based on that data, because it’s very likely future books will do at least a...
