Facebook Oculus Go Standalone VR Headset Launched for $199 and Up

Oculus has developed virtual reality headset for several years, starting with VR development kits, before launching consumer VR headsets working with either a powerful computer (Oculus Rift), or a smartphone (Oculus Gear VR). But the company – now part of Facebook – has more recently been working on an all-in-one virtual reality headset called Oculus Go that works without external hardware, and launched it today starting at $199.00. Oculus Go specifications: SoC – Qualcomm Snapdragon 821 octa-core Mobile VR Platform System Memory – Storage – 32 or 64GB storage Display – 5.5″ display with 2560 x 1440 resolution; 538ppi; up to 72 Hz refresh rate Fresnel lenses Audio – Built-in spatial audio and integrated microphone Battery – Lithium-Ion battery good for about two hours for games to up to 2.5 hours for streaming media and video. Dimensions – 190mm x 105mm x 115mm Weight – 468 grams The company explains 32GB of storage will allow for 3 HD films, 10 …

Oculus Rift Virtual Reality Development Kit 2 Becomes Open Source Hardware

Oculus Rift DK2 virtual reality headset and development kit started to ship in summer 2014. The DK2 is kind of VR headset that is connected to a more powerful computer via USB and HDMI, includes hardware for positional tracking, a 5″ display ,and two lenses for each eye. Since then the company has been purchased by Facebook, and they’ve now decided to make the headset fully open source hardware.   The release includes schematics, board layout, mechanical CAD, artwork, and specifications under a Creative Commons Attribution 4.0 license, as well as firmware under “BSD+PATENT” licenses which you’ll all find on Github. The release is divided into four main folders: Documentation with high-level specifications for the DK2 headset, sensor, and firmware. Cable with schematics and high level specifications for the cables. Custom assembly that would be hard to recreate from source. Allegedly the most complex part of the design Sensor with electrical and mechanical CAD for the positional tracking sensor. Sadly …

Facebook Zstandard “zstd” & “pzstd” Data Compression Tools Deliver High Performance & Efficiency

Ubuntu 16.04 and – I assume – other recent operating systems are still using single-thread version of file & data compression utilities such as bzip2 or gzip by default, but I’ve recently learned that compatible multi-threaded compression tools such as lbzip2, pigz or pixz have been around for a while, and you can replace the default tools by them for much faster compression and decompression on multi-core systems. This post led to further discussion about Facebook’s Zstandard 1.0 promising both smaller and faster data compression speed. The implementation is open source, released under a BSD license, and offers both zstd single threaded tool, and pzstd multi-threaded tool. So we all started to do own little tests and were impressed by the results. Some concerns were raised about patents, and development is still work-in-progess with a few bugs here and there including pzstd segfaulting on ARM. Zlib has 9 levels of compression, while Zstd has 19, so Facebook has tested all …

OpenCellular is Facebook’s (soon to be) Open Source Wireless Access Platform

A few months after Canonical and Lime Micro LimeSDR open source software defined radio aiming to be used as a development platform, but also as the base for low cost cellular or other wireless base stations, Facebook has announced their own open source wireless access platform with OpenCellular project whose goal is to lower the cost of Internet connectivity in remote areas where the infrastructure does not exist. This is how Marc Zuckerberg summarizes the project: We designed OpenCellular as an open system so anyone — from telecom operators to researchers to entrepreneurs — can build and operate wireless networks in remote places. It’s about the size of a shoe box and can support up to 1,500 people from as far as 10 kilometers away. Along with our solar-powered aircraft Aquila and high-bandwidth laser beams, OpenCellular is the next step on our journey to provide better, more affordable connectivity to bring the world closer together. But we can get some …
