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…

Pyro Accepted by the LF Deep Learning Foundation as a Hosted Project

Pyro, a deep, universal probabilistic programming language created by Uber AI, was voted in by the Linux Foundation Deep Learning Technical Board as the latest incubation project to join the foundation. “We’ve already seen an uptick in contributions to Horovod since Uber contributed the project to LF Deep Learning in December of last year. It’s really exciting to see the momentum and progress by the team,” said Ibrahim Haddad, executive director of the LF Deep Learning Foundation. “We are honored…

Early mutation in neutralizing antibody gives it flexibility to adapt to virus’s changes — ScienceDaily

In the quest to develop an effective HIV vaccine, researchers have focused attention on identifying and targeting the region of the virus’s outer envelope where a lineage of antibodies are able to dock and neutralize the virus. But true to form with HIV, these broadly neutralizing antibodies, or bnAbs, are highly complex and arise under an intricate series of events that have been difficult to trace backward to their origins and recreate. A new observation, led by researchers at the…

Open-sourcing SPARTA to make abstract interpretation easy

Abstract interpretation is a powerful static analysis framework we can use to answer questions such as: What range of values does this variable take? What are all the types of the values that can flow into this function? Is this piece of code ever executed, or is it dead? Using abstract interpretation to build a scalable tool from scratch is a daunting engineering task that generally requires a protracted development effort led by an expert. To streamline that process, we…

Join us for 5 serverless events in SF Bay Area this week

Developer Week Bay Area is happening this week and Cloudflare engineers and developer relations team members are delivering several talks around the Bay.

Practical Lessons in Machine Learning

Bot-powered credential stuffing is a scourge on the modern Internet. These attacks attempt to log into and take over a user’s account by assaulting password forms with a barrage of dictionary words and previously stolen account credentials, with the aim of performing fraudulent transactions, stealing sensitive data, and compromising personal information. At Cloudflare we’ve built a suite of technologies to combat bots, many of them grounded in Machine Learning. ML is a hot topic these days, but the literature tends…

Renewable energy generation with kites and drones

Airborne Wind Energy Systems (AWES). Credit: UC3M Airborne Wind Energy Systems (AWES) are a new kind of technology to harvest wind energy. The expensive and heavy tower and rotor of a conventional wind turbine are replaced by a light tether and an aircraft (flexible giant kites or large drones), respectively. In the so-called ground generation scheme, AWES use the tension force of the tether to move an electrical generator on the ground whereas, in fly generation scenarios, the electrical energy…

How to block new antibiotic resistance gene — ScienceDaily

A new antimicrobial-resistance gene, VCC-1, a ß-lactamase gene, has been discovered in benign close relatives of virulent Vibrio cholerae, which causes cholera. Now, a team of Canadian researchers has found a way to block the VCC-1 enzyme, which disables that resistance gene. The research is published February 19th in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology. VCC-1 was first found in Canada, by investigators from the Public Health Agency of Canada, on frozen shrimp that…

Zephy McKanna on Multi-Armed Bandits – Wayfair Tech Blog

This week, Zephy McKanna sets out to explain Multi-Armed bandits. Here at Wayfair, we are constantly testing new algorithms, product sort orders, marketing, and other messages using epsilon-first Multi-Armed Bandits – also known as A/B tests. We are also employing some more interesting MAB algorithms, like Thompson Sampling, to dynamically balance traffic during tests on low-traffic portions of the site (like holiday décor), as well as for some long-standing dynamic problems like choosing the top N among the ever-changing sales…
