Configuring servers at scale – Facebook Code

Facebook’s infrastructure consists of many geo-distributed data centers that host millions of servers. These servers run a number of systems, ranging from front-end web servers to News Feed aggregators to our messaging and live video applications. In addition to regular code pushes, we also push thousands of configuration changes to our servers every day. Thus it is fairly common for our servers to execute trillions of configuration checks. One example of a configuration check is a web server personalizing the…

Determining the bioaccumulation of 9 metals in aquatic invertebrates in mining areas — ScienceDaily

The European Union has set the deadline of 2021 for the development of Environmental Quality Standards and, in particular, for determining the threshold tissue concentration of hazardous chemical substances that can be tolerated by aquatic organisms and which pose a low risk for the preservation of their populations. A study conducted in mining areas in Asturias by the Animal Ecotoxicity and Biodiversity group led by Dr Pilar Rodriguez, through collaboration between the Department of Zoology and Animal Cellular Biology and…

Securing U.S. Democracy: Athenian Project Update

Last December, Cloudflare announced the Athenian Project to help protect U.S. state and local election websites from cyber attack. Since then, the need to protect our electoral systems has become increasingly urgent. As described by Director of National Intelligence Dan Coats, the “digital infrastructure that serves this country is literally under attack.” Just last week, we learned new details about how state election systems were targeted for cyberattack during the 2016 election. The U.S. government’s indictment of twelve Russian military…

IPv6 in China

Photo by chuttersnap / Unsplash At the end of 2017, Xinhua reported that there will be 200 Million IPv6 users inside Mainland China by the end of this year. Halfway into the year, we’re seeing a rapid growth in IPv6 users and traffic originating from Mainland China. Why does this matter? IPv6 is often referred to the next generation of IP addressing. The reality is, IPv6 is what is needed for addressing today. Taking the largest mobile network in China…

Building data services to bring education to millions, Part III

Piloting Self-Serve Analytics as a Service This post is Part III of the “Building Data Services” series (Part II here). Last month, we shared how we employ embedded analytics to power Coursera’s In-Platform Dashboards, serving ready-made descriptive and advanced analytics to partner institutions and enterprise customers. In this post, we summarize another application we piloted last year to support more custom analytical explorations for our partners: Self-Serve Analytics-as-a-Service. The target customer we had in mind was stakeholders in partner institutions…

Researchers develop DIY field imaging system

The constructed system taken earlier the summer of 2018. Credit: Alex Susko Farmers and plant breeders can now build their own automated field camera track system to collect data on dynamic plant traits, such as crop lodging and movement, as it’s happening in the field to help reduce losses in crop yield. A team of University of Minnesota researchers led by Alex Susko, doctoral candidate and member of the Precision Agriculture Center in CFANS, developed the system to capture videos…

Data Center Innovation: Developing and Broadening with the Community in Mind

Over the last few years, LinkedIn members have started to engage with the platform in exciting new ways. Instead of just posting short-form text updates, they’re also sharing long-form posts, photos, and videos. This is driving exponential growth in global site traffic demands and a corresponding increase in the demands made of our data centers. As a result, my team faced an interesting problem: we needed to find new ways to innovate for this kind of hyperscale growth. Community involvement…

Food purchases can affect climate

How much and what kind of foods you buy can have an effect on our climate.
