Spotify Modernizes Client-Side Architecture to Accelerate Service on All Devices

Engineer Carl Engström explains how lifting the 10,000 limit on Liked Songs enabled his team to address a much deeper issue and improve the listening experience of end users, whatever their device or network.    At first glance, lifting the 10,000 limit on Liked Songs seems like a simple engineering exercise. Some Reddit commentators even claimed to have identified a few lines of code that set the restriction. Why not just delete them and tidy up any gaps? As the…

Profiles in Coding: Christabelle Bosson, Uber Elevate, San Francisco

Uber Elevate takes Uber’s pioneering transportation technology to new heights with urban aerial ridesharing. In its mission to make aviation a part of everyday transportation, Uber Elevate is building an all-electric aerial mobility ecosystem that will bypass congestion on the ground and enable more seamless and efficient transportation of people and goods between cities and suburbs. To turn this vision into a reality, the Elevate team is working with aircraft manufacturers to manufacture electric Vertical Takeoff and Landing aircraft (eVTOLs)…

Synchronize Multiple ADCs With JESD204B

Shares of Analog Devices spiked after it reported second-quarter results that matched estimates from before the coronavirus outbreak, which has upended the supply chain and dented demand for some of its parts. The analog chip giant said on Wednesday that it faced faltering demand for chips used in factory equipment and cars, balanced out by soaring sales in medical devices and wireless networking gear. “Our diversification across customers, applications and market is mitigating weaker global business activity,” said Vincent Roche, chief executive…

Electric pulses precisely shape 3-D-printed metal parts

Professor Dirk Bähre (l., here with Stefan Wilhelm from his research group) and his research team at Saarland University have developed a non-contact method of transforming metal parts fabricated by a 3D printer into high-precision technical components for specialist applications. The novel method enables them to process parts made from strong, lightweight metals to produce precision-finished components with complex geometries and dimensional tolerances of a few thousandths of a millimeter. The team of manufacturing technologists combine metal 3D printing and…

Are Face Masks in Your Manufacturing Future?

At a time when a company’s current product line isn’t selling, a good business leader will look for ways to repurpose their equipment to produce what is in demand. But, for most manufacturers, having the capability to retool is an exception, not the rule. Manufacturers considering a shift to making personal protective equipment (PPE), complex machinery such as ventilators and other COVID-19-related gear are discovering how difficult switching production can be. The core reason tackling a new product is so…

Evaluation Kit Facilitates IoT Home Automation Prototyping

Download this article in PDF format. In the fast-changing Internet of Things (IoT) world, there’s no shortage of possibilities for smart-home devices. For developers, that means more design challenges than ever before. Projects, for example, can no longer take years to move from concept to market. Rapid prototyping enables an IoT company to consider client input, needs, and wishes, and quickly demonstrate what their solution would look like. It involves minimal development time and costs while providing the needed flexibility…

The Million-Mile Battery Club | Electronic Design

Most electric car batteries today last 100,000 to 200,000 miles before replacement, while most current gas-engine cars only last 150,000 miles before joining the scrap heap. So why are EV makers seek a million-mile battery? The answer is they are preparing for what comes next: Allowing EV batteries to have second lives in stationary grid storage systems by enabling a vehicle to send power back into the grid via a bidirectional charger. With a battery capable of lasting a million…

Cryptographic Implementations: Hardware vs. Software

Series: The Cryptography Handbook Modern cryptographic algorithms can be implemented using dedicated cryptographic hardware or software running on general-purpose hardware. For various reasons, dedicated cryptographic hardware provides a better solution for most applications. The table below lists reasons why hardware-based cryptographic solutions are more desirable. Secure Boot and Secure Download—What Are They and Why Are They Important? Among the everyday IoT devices that use embedded hardware are: Home devices: Wi-Fi cameras, IoT thermostats, and smoke detectors Medical devices Wearables, fitness…
