Global shutter sensors with no skew or distortion have been promised as the future of cameras for years now, but so far only a handful of products with that tech have made it to market. Now, Raspberry Pi is offering a 1.6-megapixel global shutter camera module to hobbyists for $50, providing a platform for machine vision, hobbyist shooting and more. From a report: The Raspberry Pi Global Shutter Camera uses a 6.3mm Sony IMX296 sensor, and requires a Raspberry Pi board with a CSI camera connector. Like other global shutter sensors, it works by pairing each pixel with an analog storage element, so that light signals can be captured and stored by all pixels simultaneously. By comparison, regular CMOS sensors read and store the light captured by pixels from top to bottom and left to right. That can cause diagonal skew on fast moving subjects, or very weird distortion on rotating objects like propellers.

Bing has crossed 100 million daily active users a month after the launch of its chatbot AI, according to Yusuf Mehdi, Microsoft's VP for Modern Life, Search and Devices. Engadget: He said the company is fully aware that it's still just "a small, low, single digit share player," but hey, there was a time when Bing wasn't even a part of the conversation.

Now, after the tech giant released its next-gen version, even those who haven't used it in the past are relying on it for their searches: Mehdi noted that one-third of Bing's daily active users are new to the search engine. "We see this appeal of the new Bing as a validation of our view that search is due for a reinvention and of the unique value proposition of combining Search + Answers + Chat + Creation in one experience," the VP said.

A SPAC merger brought a global "Uber for bus" startup to the Nasdaq just as tech investment was about to dry up. From a report: In July 2021 the world's tallest tower, the Burj Khalifa in Dubai, was briefly lit up in brilliant red, with animated electronic text scrolling up its height announcing "the Middle East's first $1.5 billion unicorn to list on Nasdaq." The splashy marketing was for Swvl, a company with lofty ambitions to become a hybrid of a ride-hailing app and bus service in cities across the globe. Twenty months later, the Dubai-based company's shares have dropped more than 99%. Its roughly $9 million market value is a shadow of the billion-dollar-plus valuation that once gave it so-called unicorn status.

A deal to buy Turkish transit company Volt Lines largely using Swvl shares fell apart in January. Once trumpeted by Dubai ruler Sheikh Mohammed bin Rashid Al Maktoum as a symbol of the Middle East's startup spirit, Swvl Holdings has become another example of tech-sector overreach -- and how quickly investor money dried up once superlow interest rates went away. It also shows the perils of trying to build a business that straddles emerging markets vulnerable to currency shocks as the dollar rises. Swvl was co-founded in Cairo in 2017 by former Rocket Internet SE executive Mostafa Kandil along with Ahmed Sabbah and Mahmoud Nouh. The trio started the company as a solution for commuters who didn't want to rely on public transit but couldn't pay a premium for ride-share services. Their idea: buses and vans running along routes that users could book a ride on with an app.

A week away from the March 16 launch of Baidu's ChatGPT equivalent, employees at China's biggest search-engine operator said they are racing to meet the deadline with the chatbot still struggling to perform some basic functions. From a report: To develop the artificial-intelligence-powered chatbot, dubbed Ernie Bot, hundreds of people have been working around the clock, people familiar with the project said. Other teams have been asked to lend their staff and their powerful computer chips, which Chinese companies can no longer buy because of U.S. sanctions, they said. The AI model that is the basis of the chatbot is still being trained with data ahead of the scheduled launch, a highly anticipated event in China's tech industry, some of the people said. Some employees said they haven't had sufficient time to build a well-functioning product. Baidu plans to roll out the product in stages, first opening it up for public testing to a restricted pool of users, people briefed about the plan said. Last month, Baidu said that it will embed Ernie Bot into its search engine first and will open it to the public in March.
