Application DDoS In Microservice Architectures By Scott Behrens and Bryan Payne Introduction We’d like to introduce you to one of the most devastating ways to cause service instability in modern micro-service architectures: application DDoS. A specially crafted application DDoS attack can cause cascading system failures often for a fraction of the resources needed to conduct a more traditional DDoS attack. This is due to the complex, interconnected relationships between applications. Traditional DDoS attacks focus on exhausting system resources at the…

Improve Your Communication using WiFi Calling

With so many features on our smartphones, we often forget what these devices were originally intended to do — make calls. Of course, as much time as we spend taking photos, browsing social media, shopping, and playing games on our phones, we still expect to be able to make calls without any problems. Although rare, many items can interfere with the features on any phone, no matter what network you are using. Find out how Wi-Fi calling can help improve…

Using AI for new visual storytelling techniques in VR | Engineering Blog | Facebook Code

Artificial intelligence is becoming an increasingly important tool within the artistic community to foster visual creativity. Two frequently used techniques are generative adversarial networks (GANs), which can generate visually realistic images, and style transfer, which can turn photos or videos into works of art by applying the artistic qualities of one image style — such as a painting — to other images and videos. At Facebook AI Research (FAIR), we wanted to investigate further how artists and professionals typically trained…

The modern factory represents the pinnacle of mass production technology, refined over a hundred years or more, to produce identical items for mass consumption at the lowest cost. Every manufacturing line…

LinkedIn Passes IPv6 Milestone | LinkedIn Engineering

Earlier this month, and for the first time in our company’s history, more than 50% of pages on LinkedIn were accessed over IPv6 from mobile devices in the U.S. This is another step in the internet community’s long migration to IPv6 from IPv4, which we have written about previously. Since we enabled IPv6 on our mail servers in 2013 and then on our web site in 2014, we have seen increased growth of our external IPv6 traffic. We are currently…

Cloudflare + Fight for the Future

For Net Neutrality Day on July 12, Fight for the Future (FFTF) launched a Cloudflare App installable for websites all over the world. Sites with it installed saw as many as 178 million page views prompting the users to write to their local congressional representative on the importance of Net Neutrality. All told, the FCC received over 2 million comments and Congress received millions of emails and phone calls. Screenshot of App Page for FFTF’s Battle for the Net app.…

Who will control the swarm?

Who will control the swarm? Credit: iStock/Chesky_W The world is already well on its way to a day when innumerable autonomous cars and drones buzz about, shuffling commuters to work and packages to doorsteps. In fact, there is new term for it floating around the circles of engineers and venture capitalists who hope to see the day arrive sooner rather than later: They call it “The Swarm.” But this dramatic-sounding reality raises a critical question that has yet to be…

Advancing knowledge toward more efficient electronics — ScienceDaily

A recent discovery by a team of researchers led by Tulane University advances fundamental knowledge that could one day lead to more energy-efficient computers, televisions, cell phones and other electronics. The researchers’ discovery of a new magnetic topological semimetal is featured in the latest edition of the  journal Nature Materials. The Tulane team was led by physics professor Zhiqiang Mao, the Tulane School of Science and Engineering’s Outstanding Researcher for 2017. Mao’s research, which focuses on quantum materials such as…

Engineering Uber Predictions in Real Time with ELK

Uber’s services rely on the accuracy of our event prediction and forecasting tools. From estimating rider demand on a given date to predicting when an UberEATS order will arrive, Uber uses forecasting algorithms to enhance user experiences (UX) across our product portfolio. To architect a precise and easily interpretable forecasting experience for engineering and operations, we built a custom prediction system by leveraging an open source distributed RESTful search engine composed of query engine Elasticsearch, data indexing pipeline Logstash, and…
