How Cloudflare Streams

Every day, close to 1 billion people watch video through Cloudflare. That’s 100 petabytes of video every month. Last year, video made up 73% of all internet traffic, which is why earlier today we announced Cloudflare Stream, an end to end video solution designed to bring instant video to any device and network connection. Here’s how Stream works to optimize video upload, encoding and delivery. Uploads Using Cloudflare Stream starts with a call to the Stream API to /upload a…

Fixing the Streaming Video Market

Cloudflare turns seven years old today. We launched on September 27, 2010. It was only a few days after our launch that we got our first request to support video streaming. Yet, until today, we’d avoided it. Why? Simply put: the video streaming market is screwed up. While there’s a lot of money spent on video, there are only really about 1,000 customers that do any meaningful level of streaming. This is in large part because it’s technically far too…

Stereophonic device enables objects to ‘talk’ to users

NEC Corporation today announced the development of acoustic augmented reality (AR) technology that gives a “voice” to objects that can only be heard by users of specialized wireless earphones. These advanced devices also enable users to easily identify the direction and location that the voices originate from, making this technology ideal for marketing purposes and guide services. The technology wirelessly provides “stereophonic sound,” a realistic sound field that virtually produces three dimensional sense of direction and distance for a sound.…

Cancerous Toxins Linked to Cannabis Extract — ScienceDaily

Researchers at Portland State University found benzene and other potentially cancer-causing chemicals in the vapor produced by butane hash oil, a cannabis extract. Their study raises health concerns about dabbing, or vaporizing hash oil — a practice that is growing in popularity, especially in states that have legalized medical or recreational marijuana. Dabbing is already controversial. The practice consists of placing a small amount of cannabis extract — a dab — on a heated surface and inhaling the resulting vapor.…

Researchers compare the performance of human subjects versus deep neural networks in visual searches — ScienceDaily

Before you read on, look for toothbrushes in the photo above. Find them? Both of them? If you’re like the vast majority of people, you honed in on the one near the sink, but probably took a moment or two before seeing the other, much larger one hanging on the wall. Although it is technically much more visible and not out of context, for a while at least, your brain excluded that enormous blue toothbrush in your visual search. As…

Near-Earth asteroid CubeSat goes full sail — ScienceDaily

NASA’s Near-Earth Asteroid Scout, a small satellite the size of a shoebox, designed to study asteroids close to Earth, performed a full-scale solar sail deployment test at ManTech NeXolve’s facility in Huntsville, Alabama, Sept. 13. The test was performed in an indoor clean room to ensure the deployment mechanism’s functionality after recent environmental testing. NEA Scout is a six-unit CubeSat that relies on an innovative solar sail for propulsion. It is one of 13 secondary science payloads NASA selected to…

Multithreaded rendering on Android with Litho and Infer | Engineering Blog | Facebook Code

The types of content people share on News Feed have evolved from text, to photo, to video, to rich immersive experiences like 360 and Live. As these experiences become more sophisticated, it gets more challenging to render items on screen using the traditional Android UI framework, even on today’s powerful high-end devices. On News Feed, not being able to render items quickly enough can result in awkward jitters and pauses instead of the smooth scrolling experience we want to provide.…

Engineering Restaurant Manager, our UberEATS Analytics Dashboard

At Uber, we use data analytics to architect more magical user experiences across our products. Whenever possible, we harness these data engineering capabilities to empower our partners to better serve their customers. For instance, in late 2016, the UberEATS engineering team built a comprehensive analytics dashboard that provides restaurant partners with additional insights about the health of their business. This solution had to be capable of gleaning insights from a data pipeline that was real-time, granular, highly available, and reliable.…

React 16: A look inside an API-compatible rewrite of our frontend UI library | Engineering Blog | Facebook Code

React makes it simple to build functional, component-based user interfaces on web and mobile; at Facebook, we have more than 30,000 React components in our main web repo alone. React’s simplicity and functionality has led to its adoption by hundreds of thousands of developers outside Facebook. With today’s release of React 16, we’ve completely rewritten the internals of React while keeping the public API essentially unchanged. From an engineering standpoint, it’s a bit like swapping out the engine of a…

Preparing to Celebrate Women in Tech at GHC ’17

I’ve been in the technology industry for 17 years and consider my attendance at the Grace Hopper Celebration of Women in Computing as one of the most powerful experiences of my career—and one of the most fulfilling. I’m looking forward to experiencing the celebration again this year with an amazing group of engineers from LinkedIn. It’s also a moment to reflect on the impact this event can have. Last year, while spending time in the LinkedIn booth at the GHC…
