‘GreenWeb’ to create energy-efficient web

Published

GreenWebNew York : Researchers, including an Indian-origin scientist from the University of Texas at Austin, have developed a new, open-source computer programming framework “GreenWeb” that allows people to save more battery power while browsing on mobile devices.

Developed by electrical and computer engineering professor Vijay Janapa Reddi and graduate student Yuhao Zhu, “GreenWeb” is a set of web programming language extensions that enable web developers to have more flexibility and control than ever before over the energy consumption of a website.

“Because user awareness is constantly increasing, web developers today must be conscious of energy efficiency. However, current web language standards provide developers little to no control over device energy use. We’ve taken an important step toward language-level research to enable energy-efficient mobile web computing,” said Reddi.

The researchers integrated “GreenWeb” into Google Chrome and reported energy savings of 30 to 66 per cent over Android’s default mode.

Mobile device users spend nearly two-thirds of their time browsing the web, so that amount of energy savings could result in a 20 to 40 per cent battery life extension.

“GreenWeb” more efficiently guides the web browser engine to save processor energy without sacrificing user experience.

The language extensions, implemented as CSS style rules, allow developers to express hints to the browser, which in turn conserves power when excessive computational horsepower is not necessary.

The researchers also developed “AutoGreen”, an automatic tool within the “GreenWeb” framework to assist developers in automatically making web pages energy-friendly.

The researchers have made the framework available to the public at WattWiseWeb.org and recently presented it at the “ACM SIGPLAN Conference on Programming Language Design and Implementation (PLDI)” in Santa Barbara, California.

Lockdowns in China Force Urban Communities to Defy Censorship and Vent Frustration Online

Shanghai’s rich middle class is leading a wave of online dissent over the strict and prolonged lockdowns imposed in various parts of the country. Chinese internet censorship is struggling as patience is wearing thin in many urban centers, coming up with creative forms of online protests.

Social Media Posts Revealing Lockdown Tension in Shanghai

Drawn-out lockdowns are nothing new in China as authorities insist with the nation’s zero-Covid policy since the start of the pandemic. Currently over This time around, however, metropolitan areas like Shanghai are increasingly difficult to keep quiet, given that its more than 25 million residents have seen weeks of total isolation along with food shortages and many other service interruptions.

Dozens of towns and reportedly over 300 million Chinese citizens have been affected by lockdowns of different severity. As expected, urban netizens have been most outspoken over their difficulties by finding creative ways to get around state censorship and bans placed on topics, news comments and spontaneous campaigns.

Shanghai residents have been using mobile proxies and hijacking seemingly unrelated hashtags to talk about healthcare issues, delivery failures and the overall severity of their situation. The “positive energy” that the Chinese government wants to transmit during the recent prolonged series of lockdowns does not come naturally to those counting food supplies and online censors are working hard to filter words, trending topics and undesired social media sharing.

WeChat groups and message threads are under constant monitoring. Posts questioning the zero-Covid approach have been quickly deleted, including by leading Chinese health experts like Dr. Zhong Nanshan. Video footage is soon censored and protests and investigations are quickly made to disappear.

Where this has not worked, officials have exposed banners with warnings and outright threats like “watch your own mouth or face punishment”, while drones have been patrolling the city skies. Yet, if anything, this has led to further tensions and unspoken confrontation with Shanghai’s educated and affluent middle class.

Creative Online Solutions Harnessing Civic Energy

Announcements by Chinese social media that they would be publishing the IP addresses of users who “spread rumors” have not helped either. Tech industry research has shown that much of Asia’s tech-savvy population has a habit of using mobile proxies and other privacy tools, quickly finding workarounds to browse the internet freely and talk to the world about the hottest topics.

The sheer volume of forbidden posts is already a challenge for the very censorship system, experts explain. Unable to track all trending hashtags, state workers overlook topics that speak about the US, Ukraine or other popular news. Linking human rights elsewhere to their situation, Chinese online dissidents establish their informal channels and “hijack” the conversation to share personal or publicly relevant information about the Covid suppression in their town.

Sarcastic and satirical posts still dominate. Others hope to evade the censors by replacing words from famous poems or the national anthem. One thing is certain – social media, when harnessed with the right creativity, has proven its ability to mount pressure on the government in even some of the most strictly controlled tech environments like China.
