Facebook tweaks News Feed algorithm to make content more appealing

By -

Facebook has once again made changes to its News Feed algorithm as part of its ongoing effort to keep users happy with the kinds of content they see on the site.
The social networking giant said the latest changes are based off of qualitative feedback from a sampling of Facebook users who were asked to share their daily experiences with News Feed content.
Based on this research, Facebook said it was able to rank which stories users would be interested in seeing near the top of News Feed even if they choose not to actually engage with it.Instead of using engagement actions, Facebook focused on two particular signals: The probability that users want to see a particular story at the top of their feed, and the probability they'll like, share or comment on it.
"We saw through our research that people reported having a better News Feed experience when the stories they see at the top are stories they are both likely to rate highly if asked and likely to engage with," software engineers Cheng Zhang and Si Chen wrote in a blog post.
As for what the changes mean for Pages, Facebook said it's likely to vary depending on audience and posting activity. However, there could be some impact on reach or referral traffic if a story's click rate does not match up with how much people report actually wanting to see that particular story.
Also, Pages needn't bother asking for likes and shares. Facebook said this will only create a temporary spike in metrics, which will eventually be rebalanced by ranking over time.

It finally happened. Today, all 500 of the world's top 500 supercomputers are running Linux. Linux rules supercomputing. This day has been coming since 1998, when Linux first appeared on the TOP500 Supercomputer list . Today it finally happened:  All 500 of the world's fastest supercomputers are running Linux . The last two non-Linux systems, a pair of Chinese IBM POWER computers running AIX, dropped off the  November 2017 TOP500 Supercomputer list . Overall, China now leads the supercomputing race with 202 computers to the US' 144. China also leads the US in aggregate performance. China's supercomputers represent 35.4 percent of the Top500's flops, while the US trails with 29.6 percent. With an anti-science regime in charge of the government, America will only continue to see its technological lead decline. When the  first Top500 supercomputer list was compiled in June 1993 , Linux was barely more than a toy. It hadn't even adopted Tux as its masc

Microsoft is using this week's Ignite conference to try to help clarify its collaboration-tool strategy. Here's how SharePoint, Teams and Yammer figure in the mix. Choice is good. But too much choice, especially when it comes to collaboration tools, has been a problem for Microsoft. This isn't news to customers, partners or Microsoft execs themselves. But at the company's Ignite IT Pro conference in Orlando this week, Microsoft execs took a step to try to clarify the company's strategy and messaging in this area. Microsoft Office 365 Marketing chief Ron Markezich kicked off the conference this week with a slide entitled "Microsoft 365 Teamwork: Where to Start a Conversation." That slide attempts to do what  Microsoft initially attempted with a 60-plus-page whitepaper : Clarify which collaboration tools customers should use when. The slide, which features SharePoint -- and its files, sites and content storage at the center -- is broken down into t
