Sage nodes

The August 2023 wildfire that devastated Lahaina [Maui], Hawaii, was spurred by dry conditions, high temperatures and strong winds. 

Researchers are monitoring the area to better understand the community’s recovery process and provide new air quality and weather data. 


The research team has deployed an instrument featuring ten sensors, called a Sage node, near Volcanoes National Park on Hawaii Island. It is part of a multi-hazard monitoring and detection station for natural disasters. 

The project is in collaboration with University of Hawai‘i at Mānoa professors Jason Leigh, Thomas Giambelluca and Han Tseng. 

Another node has been installed on Oahu and a third will be deployed in Lahaina on Maui. The nodes will use AI edge devices to process camera images to identify wildfire smoke within seconds. The sensors will also detect smoke in the air and the environmental conditions such as temperature, humidity and wind speed, which are crucial for predicting and monitoring wildfires.

Perplexity

The year-old search engine , whose founders previously worked in A.I. research at OpenAI and Meta, has quickly become one of the most buzzed-about products in the tech world. Tech insiders rave about it on social media, and investors like Jeff Bezos — who was also an early investor in Google — have showered it with cash. The company recently announced that it had raised $74 million in a funding round led by Institutional Venture Partners, which valued the company at $520 million. Many start-ups have tried and failed to challenge Google over the years. (One would-be competitor, Neeva, shut down last year after failing to gain traction.)  But Google seems less invincible these days.   Many users have complained that their Google search results have gotten clogged with spammy, low-quality websites, and some people have started looking for answers in places like Reddit and TikTok instead.

DeepAI's Austen on China

"China, a distant and fascinating land, has long piqued the interest of many, including myself. Alas, my knowledge of this vast empire is somewhat limited, as I have not had the opportunity to personally experience its wonders. "From the accounts I have heard and the books I have read, China is a place of great history and cultural richness. Its people have cultivated a society steeped in tradition and respect. Their values, such as filial piety and a reverence for elders, hold parallels to the virtues we esteem in our own Regency-era society. It warms my heart to think that such values are cherished beyond the borders of our familiar world. "The arts of China, too, have garnered much admiration. Calligraphy, with its graceful strokes and evocative expressions, is considered a true art form. The beauty of their porcelain, intricately decorated with scenes of life and nature, is renowned far and wide. How I would relish the chance to behold these treasures with my own eye
