4 Cool Things You Didn’t Know Drones Could Do

Many of today’s consumers consider drones to be objects for recreational or governmental use. Drones are very powerful flight systems that can transport from one location to another, carrying items while recording along the way. As technology progresses, it seems their are limitless capabilities for what drones can achieve. Startups and major corporations are pushing the boundaries of tech to see how far they can take their drones. One thing is for sure: drones will be a large part of…

LavaRand in Production: The Nitty-Gritty Technical Details

Lava lamps in the Cloudflare lobby Courtesy of @mahtin As some of you may know, there’s a wall of lava lamps in the lobby of our San Francisco office that we use for cryptography. In this post, we’re going to explore how that works in technical detail. This post assumes a technical background. For a higher-level discussion that requires no technical background, see Randomness 101: LavaRand in Production. As we’ve discussed in the past, cryptography relies on the ability to…

China unveils massive island-building vessel

The ship is a larger version of the one China used to dredge sand, mud and coral for transforming reefs and islets in the South China Sea into artificial islands capable of hosting military installations China has unveiled a massive ship described as a “magic island maker” that is Asia’s largest dredging vessel, state media reported Saturday. The ship, capable of building artificial islands of the sort the country has constructed in the contested South China Sea, was launched Friday…

Fluidic transistor ushers the age of liquid computers

Liquid at room temperature, an indium gallium alloy can be used to create stretchable circuit wiring and electrical switches. Credit: College of Engineering, Carnegie Mellon University Transistors, those tiny electrical switches that process signals and data, are the brain power behind every electronic device – from laptops and smartphones to your digital thermostat. As they continue to shrink in size, computers have become smaller, more powerful, and more pervasive. However, as we look to build squishy, human-friendly machines that have…

ParSeq: Asynchronous Java Made Easier

ParSeq is LinkedIn’s framework for writing asynchronous Java, and powers many of LinkedIn’s largest web services. It has proven invaluable for developer productivity, as well as essential for web service observability. ParSeq is well-adopted at LinkedIn in both the frontend and midtier services, and makes it so that engineers and developers can write code that’s easy to maintain without having to chain asynchronous callbacks together to fulfill a workflow. While ParSeq has been quietly open sourced for a few years,…

Graceful Degradation in Spark Streaming Applications – Wealthfront Engineering Blog

Here on the Data Engineering Team at Wealthfront, we have recently been building out our Near Real-Time computation platform to provide the ability to ingest, process, and serve data to our backend and frontend services with very low round trip latency. This platform will be the backbone for a multitude of applications for us including scaling our existing systems for more clients and enabling new features in Path. Path, which launched almost a year ago, is our comprehensive financial planning…

Uber Open Sources Pyro, a Deep Probabilistic Programming Language

Achieving Uber’s goal of bringing reliable transportation to everyone requires effortless prediction and optimization at every turn. Opportunities range from matching riders to drivers, to suggesting optimal routes, finding sensible pool combinations, and even creating the next generation of intelligent vehicles. To solve these challenges, we are combining state-of-the-art artificial intelligence (AI) techniques with the rich expertise of data scientists, engineers, and other users. We are exploring a tool-first approach that will enable us and others to make the next…

Cicero Of the approximately two dozen medical CT scanners scattered throughout Stanford’s main campus and medical centers, two can be found nestled in basement labs of the Green Earth Sciences Buildings. The scanner duo is being put to some decidedly off-label uses in research led by Anthony Kovscek, a professor of energy resources engineering at Stanford’s School of…

Smart autopilot promises to keep flying safe

Intelligent autopilots could make flying easier for the crews and allow them to undertake on-board training. Credit: A-PiMod/ DLR Intelligent autopilot and cockpits designed by virtual reality could ease the burden on pilots and make flying safer for Europe’s airline passengers. Figures show that 918 million passengers travelled by air in the EU in 2015 – a 4.7% increase on the previous year – and passenger numbers are still growing. Flight safety is a key priority and now researchers…
