A Last Call for QUIC, a giant leap for the Internet

QUIC is a new Internet transport protocol for secure, reliable and multiplexed communications. HTTP/3 builds on top of QUIC, leveraging the new features to fix performance problems such as Head-of-Line blocking. This enables web pages to load faster, especially over troublesome networks. QUIC and HTTP/3 are open standards that have been under development in the IETF for almost exactly 4 years. On October 21, 2020, following two rounds of Working Group Last Call, draft 32 of the family of documents…

This Week in PowerBites: Radioactive Diamond Batteries?

>> Electronic Design Resources.. >> Library: Article Series.. .. >> Article Series: PowerBites Nickel-Zinc Batteries Challenge Lead and Lithium for Stationary, Industrial Apps Zinc-based batteries are usually associated with the cheap but short-lived, leaky, flashlight-killing carbon-zinc primary cells. However, a new nickel-zinc-based (NiZn) battery chemistry may offer a greener, more cost-effective, solution for indoor and outdoor UPS systems, forklifts, and other specialty vehicle applications. According to ZincFive , its NiZn chemistry is similar to those used in earlier nickel-metal-hydride (NiMH) batteries,…

A roadmap for making critical infrastructure safer as natural disasters increase

Credit: Pixabay/CC0 Public Domain According to the European Union, it costs around €20 billion to repair and maintain transport infrastructure as a direct result of natural hazards. The American Society of Civil Engineers believes neglecting to maintain transport infrastructure could have dire economic consequences, including a loss of 2.5 million jobs and $7 trillion in business sales by 2025—figures which could rise by 16 percent as a result of climate change. In a paper published by the journal Science of…

A Virtual Product Management Internship Experience

In July 2020, I joined Cloudflare as a Product Management Intern on the DDoS (Distributed Denial of Service) team to enhance the benefits that Network Analytics brings to our customers. In the following, I am excited to share with you my experience with remote working as an intern, and how I acclimatized into Cloudflare. I also give details about what my work entailed and how we approached the process of Product Management. Onboarding to Cloudflare during COVID19 As a long-time…

Takeaways from the Latest Arm DevSummit

The Arm DevSummit was interesting this year for a variety of reasons, including its recent acquisition by Nvidia. One of the key announcements was the Cassini Project, which includes standards such as Arm’s SystemReady and the PARSEC project that expands the Arm Platform Security Architecture (PSA) into the world of containers. A host of sessions covered everything from Amazon’s AWS Graviton 2 Neoverse-based processor to security, as well as the transition from 32- to 64-bit processors in the smartphone space.…

Magnet: A scalable and performant shuffle architecture for Apache Spark

Figure 10: Increase of local shuffle read data size with Magnet-enabled jobs Conclusion and future work In this blog post, we have introduced Magnet shuffle service, a next-gen shuffle architecture for Apache Spark. Magnet improves the overall efficiency, reliability, and scalability of the shuffle operation in Spark. Recently, we have also seen other solutions proposed in the industry that target the shuffle process, specifically Cosco, Riffle, Zeus, and Sailfish. We have made a comparison between Magnet and these other solutions,…

A human motion capture system using a single wearable camera

MonoEye captures 3D body pose as well as the user’s perspective. MonoEye is based on a single ultra-wide fisheye camera worn on the user’s chest, enabling activity capture in everyday life. Credit: Tokyo Institute of Technology Researchers at Tokyo Institute of Technology (Tokyo Tech) and Carnegie Mellon University have together developed a new human motion capture system that consists of a single ultra-wide fisheye camera mounted on the user’s chest. The simplicity of their system could be conducive to a…

How Facebook is bringing QUIC to billions

We are replacing the de facto protocol the internet has used for decades with QUIC, the latest and most radical step we’ve taken to optimize our network protocols to create a better experience for people on our services. Today, more than 75 percent of our internet traffic uses QUIC and HTTP/3 (we refer to QUIC and HTTP/3 together as QUIC). QUIC has shown significant improvements in several metrics, including request errors, tail latency, response header size, and numerous others that…

This beetle can survive getting run over by a car. Engineers are figuring out how.

The diabolical ironclad beetle has puzzle piece-like blades in its abdomen that “delaminate” to prevent the beetle’s exoskeleton from suddenly failing under immense force. Purdue researchers simulated this mechanism using 3D-printed versions of the blades. Credit: Purdue University/Maryam Hosseini and Pablo Zavattieri Getting run over by a car is not a near-death experience for the diabolical ironclad beetle. How the beetle survives could inspire the development of new materials with the same herculean toughness, engineers show in a paper published…
