Now Streaming! – Netflix TechBlog – Medium

Compression Performance In December 2016, we introduced AVCHi-Mobile and VP9-Mobile encodes for downloads. For these mobile encodes, several changes led to improved compression performance over per-title encodes, including longer GOPs, flexible encoder settings and per-chunk optimization. These streams serve as our high quality baseline for H.264/AVC and VP9 encoding with traditional rate control settings. The graph below (Fig. 3) demonstrates how the combination of Dynamic Optimization with shot-based encoding further improves compression efficiency. We plot the bitrate-VMAF curves of our…

A wireless patch for monitoring emergency-room patients

A small, wireless patch developed by EPFL spin-off Smartcardia can measure emergency-room patients’ vital signs with the same reliability as existing systems involving cumbersome cables. After extensive testing at several hospitals, the device recently obtained the European Union’s CE marking for medical devices and will be launched on the market in the coming days. To make the right decisions, emergency-room doctors need to be able to continuously monitor their patients’ vital signs, including temperature, pulse, blood pressure, blood oxygen levels,…

Reykjavík, Cloudflare’s northernmost location

Iceland is a small country in Northern Europe, a land of active volcanoes and boiling hot geysers. The geology and climate creates unique conditions for running compute power. With an abundance of green electricity and natural cooling, many companies are placing high power machines in Iceland to run power intensive, heat generating operations. Reykjavík is our 125th location globally. Connecting to the rest of the world A unique aspect about Iceland relates to how it connects to the Internet, being…

Rigor mortis in worms offers new insight into death — ScienceDaily

A dying worm experiences rigor mortis early in the death process, rather than after the main event as it is for humans, according to a new study by an international team of scientists at UCL and Washington University. The study, published in the journal Cell Reports, is the first discovery of rigor mortis in worms and provides new insight into the process of ‘organismal’ death. In legal and medical terms, death is defined as the moment at which the heart…

Engineering team develops radiation-resistant computers capable of high-performance computing in the harshness of space

The Pitt H6 system’s dual high-resolution cameras can take 2448 x 2050 pixel images of Earth from the International Space Station Credit: Swanson School of Engineering In T minus 8,760 hours, or roughly one year, the Space Test Program-Houston 6 (STP-H6) hybrid and reconfigurable space supercomputer will board the International Space Station.

The real cause of large DDoS

A week ago we published a story about new amplification attacks using memcached protocol on UDP port 11211. A few things happened since then: Let’s take a deep breath and discuss why such large DDoS attacks are even possible on the modern internet. Large attacks use IP spoofing CC BY-SA 2.0 image by DaPuglet All the gigantic headline-grabbing attacks are what we call “L3” (Layer 3 OSI[1]). This kind of attack has a common trait – the malicious software sends…
