Now teams of any size can turn off their VPN

Using a VPN is painful. Logging-in interrupts your workflow. You have to remember a separate set of credentials, which your administrator has to manage. The VPN slows you down when you’re away from the office. Beyond just inconvenience, a VPN can pose a real security risk. A single infected device or malicious user can compromise your network once inside the perimeter. In response, large enterprises have deployed expensive zero trust solutions. The name sounds counterintuitive – don’t we want to…

A Differencing Engine for Digital Forensics in the Cloud

Forest Monsen and Kevin Glisson, Netflix Security Intelligence and Response Team Can you spot the difference? Hint: it’s not the bow tie. The Netflix Security Intelligence and Response Team (SIRT) announces the release of Diffy under an Apache 2.0 license. Diffy is a triage tool to help digital forensics and incident response (DFIR) teams quickly identify compromised hosts on which to focus their response, during a security incident on cloud architectures. Features Efficiently highlights outliers in security-relevant instance behavior. For example,…

An efficient system for self-contained executables – Facebook Code

Distributing large pieces of software to thousands of machines with a wide variety of configurations can pose a significant operational challenge, requiring a process to identify and copy precisely the right combination of dependent libraries and data files for each device. To make this faster, more robust, and more efficient, we have developed and deployed XARs, or eXecutable ARchives, a system for distributing self-contained executables that encapsulate both data and code dependencies. Our research has demonstrated that XARs can deliver…

Enhancing the Quality of Uber’s Maps with Metrics Computation

We previously highlighted some of the presentations delivered during our second annual Uber Technology Day. In this article, engineering senior software engineer and Uber Tech Day presenter Ines Viskic discusses how we ensure the accuracy of our maps through quality metrics. On the surface, Uber’s ridesharing technology may seem simple: a user requests a ride from the app, and a driver arrives to take them to their destination. Behind the scenes, however, a giant infrastructure consisting of thousands of services…

Dutch city to unveil world’s first 3D-printed housing complex

The southern Dutch city of Eindhoven plans to unveil the world’s first 3-D-printed housing complex next year, which its inventors believe could revolutionise the building industry by speeding up and customising construction. Printed in concrete by a robotic arm, the project backed by the city council, Eindhoven Technical University and several construction companies aims to see its first three-bedroomed home go up by June 2019. Known as Project Milestone, a housing complex of five homes of various shapes and…

Can airships take scenic flights back to the future?

A concept airship, the Aether, which Mr Henderson showed his research participants so they could conceptualise what a modern airship might be like. Credit: Massey University Massey University School of Aviation assistant lecturer Isaac Henderson has always been fascinated by airships, so he embarked on a master’s thesis to find out if they could be brought back into the mainstream. “We are starting to see modern airships in the freight and logistics sector, but very few people think they can…

Unanswered Questions About the FIU Bridge Collapse

Last March 15, an innovatively-designed pedestrian bridge installed for less than a week suddenly collapsed onto a busy roadway in Florida International University, killing six people and injuring several more.  Although many bridges have been erected successfully using the technique known as accelerated bridge construction used for this bridge, this was one of the first times such a bridge failed during construction, and so both the engineering community as well as the public at large would like to know what…

VRE4EIC releases video tutorials on how to build virtual research environments

Credit: ERCIM EEIG VRE4EIC, an H2020 European research project, has released a series of video tutorials. Short online videos explain how to build a virtual research environment (VRE) or to enhance an existing VRE. Researchers can access and use more and more research data in the digital age. They can use this data to obtain new insights, especially by combining data sets with other data. Various projects are already building e-Research Infrastructures (e-RIs) to give researchers access to publicly funded…

The next chapter – Facebook Code

Today nearly 4 billion people globally do not have access to the Internet. It’s why Facebook, along with many other companies and governments, is investing heavily to address the three key barriers to getting everyone, everywhere online: availability, affordability, and awareness. Part of that investment has been in developing next-generation connectivity technologies like Aquila, a high altitude platform station (HAPS) system. This has involved a lot of trial and error. When we started the Aquila program back in 2014, very few companies…
