Project Falco joins SONiC Community (Software for Open Networking in the Cloud)

The Production Engineering team at LinkedIn quickly recognized the value that SONiC and its open source community would bring as the network operating system for our Project Altair-defined architecture data center fabric. As discussed in earlier blog posts, our requirements for a switching platform are to be one that allows us to be more flexible in our system design choices, while abstracting away complexity. We ensure this flexibility through a set of predefined criteria: Run our silicon of choice on…

The Athenian Project: Helping Protect Elections

From cyberattacks on election infrastructure, to attempted hacking of voting machines, to attacks on campaign websites, the last few years have brought us unprecedented attempts to use online vulnerabilities to affect elections both in the United States and abroad. In the United States, the Department of Homeland Security reported that individuals tried to hack voter registration files or public election sites in 21 states prior to the 2016 elections. In Europe, hackers targeted not only the campaign of Emmanuel Macron…

Spotify Retro Kit | Labs

TL;DR: We have created the Retro Kit. It can be downloaded by following this link. Historically at Spotify there has been an Agile Coach attached to each team. That coach has, among other things, helped the team to improve their processes. A central piece to that improvement are regular retrospectives where teams reflect on their way of working to continuously become better in what they do. As the role is currently evolving the coaches will take a more holistic stance…

Bicycles reacting to speed for stable cycling

Credit: University of Twente A Dutch consortium including the University of Twente developed an electrical bicycle that prevents elderly people from falling. The smart assistive bicycle, called SOFIE, increases stability by via drive-off assistance and by automatically lowering the saddle at low speeds. The UT, Indes and Roessingh Research and Development (RRD) worked together on this science-based bike development. The scientific work of Vera Bulsink, Ph.D. student at the UT, co-developed the design and increased the stability of the prototype.…

Credit: Vanderbilt University A team of Vanderbilt University scientists and engineers led by Professor John P. Wikswo has won an R&D 100 Award for their MultiWell MicroFormulator. The MultiWell MicroFormulator, developed at Vanderbilt and commercialized by CN Bio Innovations in the United Kingdom, provides customized real-time formulation, delivery and removal of cell culture media to each well of a 96-well plate for drug delivery,…

Engineers scrap the stethoscope, measure vital signs with radio waves

A radio frequency identification tag. Credit: Cornell University No visit to the doctor’s office is complete without a blood-pressure cuff squeezing your arm and a cold stethoscope placed on your chest. But what if your vital signs could be gathered, without contact, as you sit in the waiting room or the comfort of your own home? Cornell University engineers have demonstrated a method for gathering blood pressure, heart rate and breath rate using a cheap and covert system of radio-frequency…

Drug discovery could accelerate hugely with machine learning

Drug discovery could be significantly accelerated thanks to a new high precision machine-learning model, developed by an international collaboration of researchers, including the University of Warwick. The algorithm – partly devised by Dr James Kermode from Warwick’s School of Engineering – can accurately predict the interactions between a protein and a drug molecule based on a handful of reference experiments or simulations. Using just a few training references, it can predict whether or not a candidate drug molecule will…

Inside the infamous Mirai IoT Botnet: A Retrospective Analysis

This is a guest post by Elie Bursztein who writes about security and anti-abuse research. It was first published on his blog and has been lightly edited. This post provides a retrospective analysis of Mirai — the infamous Internet-of-Things botnet that took down major websites via massive distributed denial-of-service using hundreds of thousands of compromised Internet-Of-Things devices. This research was conducted by a team of researchers from Cloudflare, Georgia Tech, Google, Akamai, the University of Illinois, the University of Michigan,…

Stopping fraudsters by changing products – Lyft Engineering

This medium post is on joint work from the Fraud and Identity teams @Lyft. Key contributors include Sam King, Will Megson, Steven Liu, Mike Ross, Ryan Choi, Ryan McGowan, Glen Robertson, Adam Wushensky, Donald Chen, Helen Lau, and Siwei Shen. Goals Our overall goal is to prevent account takeover, stop scripts and automated apps from accessing our servers, and minimize financial loss due to fraud. We focused our efforts on identifying three fundamental properties: Identifying automation or non-human traffic. Identifying…

2017 Year in review: Software across the stack | Engineering Blog | Facebook Code

This week we’re publishing a series of posts looking back at the technologies and advancements Facebook engineers introduced in 2017. Read our previous posts from this week about data centers, connectivity, and building immersive experiences. Facebook engineers write, edit, test, and ship thousands of code changes every day. In 2017, we made several optimizations across this workflow that have helped minimize the amount of time engineers spent waiting on machines, even as the number of engineers and amount of code…
