High School in China Installs Facial Recognition Cameras to Monitor Students’ Attentiveness

A high school in Hangzhou City, Zhejiang Province located on the eastern coast of China, has employed facial recognition technology to monitor students’ attentiveness in class.

At Hangzhou Number 11 High School, three cameras at the front of the classroom scan students’ faces every 30 seconds, analyzing their facial expressions to detect their mood, according to a May 16 report in the state-run newspaper The Paper.

The different moods—surprised, sad, antipathy, angry, happy, afraid, neutral—are recorded and averaged during each class.

A display screen, only visible to the teacher, shows the data in real-time. A certain value is determined as a student not paying enough attention.

A video shot by Zhejiang Daily Press revealed that the system—coined the “smart classroom behavior management system” by the school—also analyzes students’ actions, categorized into: reading, listening, writing, standing up, raising hands, and leaning on the desk.

An electronic screen also displays a list of student names deemed “not paying attention.”

The school began using the technology at the end of March, vice principal Zhang Guanchao told The Paper. Zhang added that students felt like they were being monitored when the system was first put in place, but have since gotten used to it.

How the “Math Men” Overthrew the “Mad Men”

Once, Mad Men ruled advertising. They’ve now been eclipsed by Math Men — the engineers and data scientists whose province is machines, algorithms, pureed data, and artificial intelligence. Yet Math Men are beleaguered, as Mark Zuckerberg demonstrated when he humbled himself before Congress, in April. Math Men’s adoration of data — coupled with their truculence and an arrogant conviction that their ‘science’ is nearly flawless — has aroused government anger, much as Microsoft did two decades ago.

The power of Math Men is awesome. Google and Facebook each has a market value exceeding the combined value of the six largest advertising and marketing holding companies. Together, they claim six out of every ten dollars spent on digital advertising, and nine out of ten new digital ad dollars. They have become more dominant in what is estimated to be an up to two-trillion-dollar annual global advertising and marketing business. Facebook alone generates more ad dollars than all of America’s newspapers, and Google has twice the ad revenues of Facebook.

Bitcoin driving huge electricity demand, environmental impact

In a normal year, demand for electric power in Chelan County grows by perhaps 4 megawatts ­­— enough for around 2,250 homes — as new residents arrive and as businesses start or expand. But since January 2017, as Bitcoin enthusiasts bid up the price of the currency, eager miners have requested a staggering 210 megawatts for mines they want to build in Chelan County. That’s nearly as much as the county and its 73,000 residents were already using. And because it is a public utility, the PUD staff is obligated to consider every request.

The scale of some new requests is mind-boggling. Until recently, the largest mines in Chelan County used five megawatts or less. In the past six months, by contrast, miners have requested loads of 50 megawatts and, in several cases, 100 megawatts. By comparison, a fruit warehouse uses around 2.5 megawatts.
