Cloudflare’s Always Online and the Internet Archive Team Up to Fight Origin Errors

Every day, all across the Internet, something bad but entirely normal happens: thousands of origin servers go down, resulting in connection errors and frustrated users. Cloudflare’s users collectively spend over four and a half years each day waiting for unreachable origin servers to respond with error messages. But visitors don’t want to see error pages, they want to see content! Today is exciting for all those who want the Internet to be stronger, more resilient, and have important redundancies: Cloudflare…

2020 Corvette: The Eighth Generation

TFT-LCD displays are ubiquitous in modern cars, from instrument clusters (Fig. 1) to center-stacked touchscreens, rear-seat entertainment, and more. With displays playing an increasingly critical role in helping the driver navigate the road, their ability to accurately report information is critical for the safety of car occupants. Concurrently, rear-seat entertainment displays require high-quality images that don’t diminish the movie’s intended dramatic effects. 1. Local dimming for a true black display. While the size and resolution of automotive displays have grown,…

Good Code Means Secure Code

IAR Systems is known for its IAR Embedded Workbench along with a host of security and embedded development tools like the Visual State state-machine model development toolkit. The company complements these with evaluation kits that highlight the hardware and its software. The focus of this article is the IAR RISC-V GD32V evaluation board built around the GigaDevice Semiconductor GD32VF103 microcontroller (Fig. 1). This micro has up to 128 kB of on-chip flash memory compared to the SiFive HiFive RISC-V chip…

An Italian Supercar, the 2021 Maserati MC20: A Gallery

Italian carmaker Maserati is coming out with its first high-end sportscar in 15 years, the $243,000 MC20. The MC stands for Maserati Corse (Maserati Racing), and the 20 for 2020. But eager buyers will have to wait until about the middle of next year before they can buy one. The sleek roadster is powered by a 630 hp V6 that gives it a top speed of 202 mph. The MC20 is the first of 13 new cars the company will…

An operational amplifier fabricated using a 2-D semiconductor

September 14, 2020 feature Schematic of the furnace setup used for the CVD growth of our MoS2 films. The process results in almost 1 cm2 film of MoS2 on the sapphire substrate. The isolated monolayer single crystal triangular grains of MoS2 formed on the outer edges of the growth substrate quickly get denser and coalesce into a continuous film of monolayer MoS2 towards the inner part of the sample.

Light processing improves robotic sensing, study finds

Understanding how humans process light could improve autonomous driving at high speed, which requires improved machine vision to avoid potholes and other obstacles. Credit: Bryan-College Station Eagle/Laura McKenzie A team of Army researchers uncovered how the human brain processes bright and contrasting light, which they say is a key to improving robotic sensing and enabling autonomous agents to team with humans. To enable developments in autonomy, a top Army priority, machine sensing must be resilient across changing environments, researchers said.…

Nvidia to Buy Arm in Deal Valued at About $40 Billion

Nvidia said that it would buy chip designer Arm from SoftBank in a cash-and-stock deal valued at up to $40 billion, a move that could reshape the landscape of the global semiconductor industry. If the deal closes, it would transform Nvidia into one of the most dominant players in the market for chips used in smartphones. The deal would also strengthen the Santa Clara, California-based company’s stature in other segments of the technology industry, including the Internet of Things—tiny computers…

Neither Hype Nor Magic: AI Advancements Expected to Take Robotics Industry by Storm

To kick off the third day of RIA’s Robotics Week, a panel of robotics executives discussed how the industry is poising itself for the implementation of complex household robots. What advancements does the industry need to achieve close human-robot interaction? What will that robot look like? Will it be treated like the beloved “Jetsons” character? Robots of the future won’t be designed to do one task, especially if they are designed for home use. How to use robot technology in…
