LazyTruth: Chrome Extension That Fact-Checks Rumours in Chain Emails

Ever received email forwards that make outrageous claims or carry old urban legends that have been debunked a million times in the past? No? Then you must not have gullible friends or crazy relatives abroad who love to believe and forward everything they read in emails. For the rest, it’s a constant attack on our intelligence and factual sanctity, and we hate this from our guts.

You have two options to deal with such chain letters – delete it or, well… forward it again. Or if you are willing to go the extra mile, you can do your own research on websites such as and – an excellent online repository of urban legends – and carefully type out a reply, with cross-references, debunking whatever rumour was in the email. I did this a few times in the past, but then stopped wasting my time after they failed to have the intended effect on the recipients. Now, there is a new tool to tackle this problem.


Matt Stempeck and his team at MIT's Media Lab has developed LazyTruth, a plug-in for Chrome that automatically scans email for information that and Politifact have deemed false. When you open a forwarded email, an “Ask LazyTruth” button appears at the bottom inviting you to investigate. The software checks the email against data pulled from several fact checking websites, and if something doesn't check out, it'll provide a few words of correction and a link to where you can find out more. You can then easily pass that verified information back to the email's sender. The sender will either stop speaking to you for being a snob, which is well and good, or continue sending more email forwards unfazed. But at least, you tried.

For now, LazyTruth can only match exact strings against Stempeck’s huge and growing database of chain letters and their variations. Down the road Stempeck plans to add more kinds of filters to LazyTruth to catch rumours like urban myths, hoaxes, false security threats, etc., but for now the tool is limited to political tall tales.

How to Record CPU and Memory Usage Over Time in Windows?

Whenever the computer is lagging or some application is taking too long to respond, we usually fire up task manager and look under the Performance tab or under Processes to check on processor utilization or the amount of free memory available. The task manager is ideal for real-time analysis of CPU and memory utilization. It even displays a short history of CPU utilization in the form of a graph. You get a small time-window, about 30 seconds or so, depending on how large the viewing area is.

How to Schedule Changes to Your Facebook Page Cover Photo

Facebook’s current layout, the so called Timeline, features a prominent, large cover photo that some people are using in a lot of different creative ways. Timeline is also available for Facebook Pages that people can use to promote their website or business or event. Although you can change the cover photo as often as you like, it’s meant to be static – something which you design and leave it for at least a few weeks or months like a redesigned website. However, there are times when you may want to change the cover photo frequently and periodically to match event dates or some special promotion that you are running or plan to run. So, here is how you can do that.
