Engineers advance the capability of wearable tech

Creating the perfect wearable device to monitor muscle movement, heart rate and other tiny bio-signals without breaking the bank has inspired scientists to look for a simpler and more affordable tool. Now, a team of researchers at UBC’s Okanagan campus have developed a practical way to monitor and interpret human motion, in what may be the missing piece of the puzzle when it comes to wearable technology. What started as research to create an ultra-stretchable sensor transformed into a…

Uncovering Inconsistent Keychain Behavior While Fixing a Valet iOS Bug

Crowdworking: The Future of Work

The term crowdsourcing was used for the first time in 2005 to christen the practice of outsourcing work to a crowd of skilled people. Perhaps the best way to understand how crowdsourcing works is the example of ‘Wikipedia’ – this comprehensive encyclopedia owes its success to a large number of contributors from across the globe, who collect and update the information on the platform on their own. In the course of time, crowdsourcing has become quite a trend in the…

Under the hood: Suicide prevention tools powered by AI | Engineering Blog | Facebook Code

Suicide is the second most common cause of death for people ages 15-29. Research has found that one of the best ways to prevent suicide is for those in distress to hear from people who care about them.

Laser technology takes Maya archeologists where they’ve never gone before — ScienceDaily

With the help of airborne laser mapping technology, a team of archaeologists, led by University of Arizona professor Takeshi Inomata, is exploring on a larger scale than ever before the history and spread of settlement at the ancient Maya site of Ceibal in Guatemala. In a new paper published in the journal PLOS ONE, Inomata and his colleagues explain how they commissioned the use of LiDAR, or light detection and ranging, technology to map a significantly larger area of Ceibal…

Validating Leaked Passwords with k-Anonymity

Today, v2 of Pwned Passwords was released as part of the Have I Been Pwned service offered by Troy Hunt. Containing over half a billion real world leaked passwords, this database provides a vital tool for correcting the course of how the industry combats modern threats against password security. I have written about how we need to rethink password security and Pwned Passwords v2 in the following post: How Developers Got Password Security So Wrong. Instead, in this post I…
