Scaling Knowledge Access and Retrieval at Airbnb – Airbnb Engineering & Data Science – Medium

Location Data in the Knowledge Graph Before the summer, the main use of the knowledge graph was enabling searching our taxonomy for experiences associated with those tags. searching for “Hiking” a tag in our taxonomy My main project for the summer was introducing the concept of locations. Why locations? Two main reasons: Easily traverse Airbnb inventory by location This goes back to what we discussed above with the graph structure enabling easy traversal along relationships. Because of this, it intuitively makes sense…

Warmer wetsuit will increase Navy dive time

From left, graduate student Anton Cottrill, Dr. Jacopo Buongiorno and Dr. Michael Strano try out their neoprene wetsuits at a pool at MIT’s athletic center. Cottrill is holding the pressure tank used to treat the wetsuits with heavy inert gasses. To protect Navy divers in freezing conditions, the Office of Naval Research is sponsoring work to design a wetsuit mirroring the insulating properties of animal blubber.

Raising gopher tortoises in captivity may boost wild populations — ScienceDaily

Research from the University of Georgia indicates that head-starting — raising a species in captivity and releasing it into a protected habitat after it has grown large enough to be less vulnerable to predators — is a useful intervention for boosting the state’s gopher tortoise population, which has been declining in numbers for decades due to predation, poaching and loss of suitable habitat. Seventy percent of head-started tortoises raised from donor eggs were still alive a year after release at…

At Home for the Summer with Wayfair Engineering – Wayfair Tech Blog

This past summer, Wayfair welcomed 47 software engineering interns to its Boston headquarters. Traveling from 27 different universities across the United States, these interns were immersed in a summer internship that would challenge them to be critical thinkers, innovators, and collaborative team members as they partnered up with engineering teams to solve complex business problems. Outside of their work experience, our interns had the opportunity to grow and learn through different programs hosted by the Campus Recruiting team. From a…

Recap: Our 3rd Performance Engineering Meetup

Once per quarter, the LinkedIn Performance Engineering meetup brings together engineers passionate about performance and efficiency from across the San Francisco Bay Area. The meetup is a great way for engineers to meet, share notes, and learn from each other on topics like performance measurements, monitoring, optimizations, and culture. In mid-July, we hosted the third event in this meetup series at our Sunnyvale campus. Thank you to everyone who attended the event and made it a success! For updates on…

Engineers are developing a small cooled turbine to make drones more efficient

Southwest Research Institute engineers are developing a cooled, radial gas turbine for a small generator that provides thousands of hours of electricity to an unmanned aerial vehicle (UAV), a significant improvement to current UAV turbines that only operate a few hundred hours before wearing out. Turbines are rotary mechanical devices that, when combined with a generator, produce electrical power. “This turbine is part of a generator that’s similar to what the average person might use to generate electricity in…

Introducing cstar: The Spotify Cassandra orchestration tool, now open source

Today, we announce that we are open sourcing cstar, our Cassandra orchestration tool. Operating Cassandra is not always an easy task. It has a myriad of knobs you can tune that affect performance, security, data consistency etc. Very often you need to run a specific set of shell commands on each node of a cluster, usually in some coordination to avoid the cluster being down. This can be done manually for small clusters, but can get tricky and time consuming…

Building Switch Software at Scale and in the Open – Facebook Code

WHAT THE RESEARCH IS: The Facebook open switching system (FBOSS) is switch software created specifically to address the needs of a large, rapidly growing network. At ACM SIGCOMM 2018, we shared new details about the open source version of FBOSS and our experiences and challenges using FBOSS in the Facebook network. HOW IT WORKS: To make FBOSS easier to implement, maintain, and update, we developed it as if we were building a large-scale software service. The code is leaner than…
