Cloudflare Registrar at three months

We announced Cloudflare Registrar in September. We launched the product by making it available in waves to our existing customers. During that time we gathered feedback and continued making improvements to the product while also adding more TLDs. Staring today, we’re excited to make Cloudflare Registrar available to all of our customers. Cloudflare Registrar only charges you what we pay to the registry for your domain and any user can now rely on that at-cost pricing to manage their domain.…

Researchers engineer a tougher fiber — ScienceDaily

North Carolina State University researchers have developed a fiber that combines the elasticity of rubber with the strength of a metal, resulting in a tougher material that could be incorporated into soft robotics, packaging materials or next-generation textiles. “A good way of explaining the material is to think of rubber bands and metal wires,” says Michael Dickey, corresponding author of a paper on the work and Alcoa Professor of Chemical and Biomolecular Engineering at NC State. “A rubber band can…

Predicting the monsoon a year ahead — ScienceDaily

With average precipitation of 35 inches per four-month season over an area encompassing most of the Indian subcontinent, the South Asia summer monsoon is intense, only partly understood, and notoriously difficult to predict. Until now, according to findings by Nir Y. Krakauer, a City College of New York civil engineer. Because of the monsoon’s enormous impact on these sectors, his research is of importance to a range of activities, including agriculture, industry, fishing and hydropower. A frequent visitor to the…

Captured carbon dioxide converts into oxalic acid to process rare earth elements — ScienceDaily

Until now, carbon dioxide has been dumped in oceans or buried underground. Industry has been reluctant to implement carbon dioxide scrubbers in facilities due to cost and footprint. What if we could not only capture carbon dioxide, but convert it into something useful? S. Komar Kawatra and his students have tackled that challenge, and they’re having some success. A team lead by Kawatra, a professor of chemical engineering at Michigan Technological University, his PhD students, Sriram Valluri and Victor Claremboux,…

Materials with a kagome lattice pattern exhibit ‘negative magnetism’ and long-sought ‘flat-band’ electrons — ScienceDaily

Taking their name from an intricate Japanese basket pattern, kagome magnets are thought to have electronic properties that could be valuable for future quantum devices and applications. Theories predict that some electrons in these materials have exotic, so-called topological behaviors and others behave somewhat like graphene, another material prized for its potential for new types of electronics. Now, an international team led by researchers at Princeton University has observed that some of the electrons in these magnets behave collectively, like…

How to Fail at Accessibility – Several People Are Coding

Testing What does accessibility on the web even mean? It is very broadly scoped, but thankfully also thoroughly documented. The W3C established what is known as the Web Content Accessibility Guidelines, or WCAG. If you check out this lovely doc, you’ll find everything you’ve ever wanted to know about web accessibility in a lengthy format. A screenshot from the Web Content Accessibility Guidelines on W3C.org These guidelines break down accessibility compliance to three grades: Levels A, AA, and AAA, with specific…

Creating Custom Plugins with Fusion.js, Uber’s Open Source Web Framework

Plugins are a core element of Fusion.js, Uber’s open source universal web framework, and its architecture. Plugins can be used to encapsulate functions, which are reused in different parts of the application. Examples of functions encapsulated in plugins are logging, translations, implementation of libraries and integration with data sources. A number of official plugins are provided by Fusion.js, and they allow developers to build complex applications without having to write their own plugins. However, the framework also enables developers to…

A nonvolatile spintronics-based 50uW microcontroller unit operating at 200MHz

Photo of the fabricated microcontroller unit chip. Credit: IEEE Researchers at Tohoku University have announced the development of a nonvolatile microcontroller unit (MCU) which achieves both high performance and ultra-low power by utilizing spintronics-based VLSI design technology. The demand for low-power, high-performance microcontroller units (MCUs) has been increasing for power-supply-critical Internet-of-Things (IoT) sensor node applications. In sensor node applications, a distributed network of sensors extracts and gathers information, which is processed by MCUs and transmitted to a cloud-based data center.…

Releasing React Hooks for React 16.8

WHAT’S NEW: We’ve released React Hooks, a powerful new way to write components and reuse code between them. React 16.8 is the first stable React release with support for Hooks. React Native will also support Hooks in its 0.59 release. Hooks are fully backward compatible and work alongside your existing code. WHY IT MATTERS: Hooks provide a way to reuse code with encapsulated state and side effects via functions. Hooks let us organize the logic inside a component into reusable isolated…

The Present and Future of Apache Hadoop: A Community Meetup at LinkedIn

Last but certainly not least, Microsoft’s Virajith Jalaparti (left) and Ashvin Agrawal (right) discussed the evolution of the “provided storage” feature in HDFS, which allows for HDFS clients to transparently access external storage systems (such as Azure Data Lake Storage or Amazon S3). They described a mechanism whereby the NameNode would “mount” an external store as part of its own namespace, and clients would be able to access the data as if it resided on HDFS itself. The DataNodes, which…
