Filed under
Android

Ricoh’s compact “Theta V” 360° camera runs Android on a Snapdragon 625, and offers WiFi, Bluetooth, and 4K imaging and live streaming.

Ricoh opened preorders for its Theta V 360° camera for $429, with shipments due in September. This update to the $349 Theta S has a similar 130.6 x 45.2 x 22.9mm footprint and 121-gram weight, but offers far greater image quality. The camera leverages an improved imaging algorithm, as well as dual 12-megapixel 1/ 2.3-inch sensors, to produce 3840 x 1920 (4K) resolution @ 30fps videos or stills, up from the 1920 x 960 pixels on the Theta S. Onboard WiFi and Bluetooth enables live, up to 4K streaming, as well as remote shooting.

  • Employers Seek Open Source Expertise -- But You Should Already Know That

    The latest insight about demand for open source expertise among employers comes from the 2017 Open Source Jobs Report, which was sponsored by the Linux Foundation. Most previous iterations of the report were called the Linux Jobs Report, but they focused on the same themes.

  • Kolab for Open Power

    Among a variety of deliberations concerning the security and transparency of a little Kolab thing running anywhere — at home, rented space or hybrid cloud — this post is about the transparency of the hardware layer, and our ongoing efforts to make that so.

    We have said what, why and how on LWN, at events like FOSDEM (with a supplemental interview), at FSFE Summits, various other occasions, and perhaps your next opportunity to get acquainted with the message is at the OpenPOWER Summit in Barcelona — when I say “we”, I mean one of our most widely respected and prominent people, Georg Greve.

  • Ocado Technology's Kubermesh

    Instead of relying on servers concentrated in one large data center, the new Kubermesh is designed to simplify data-center architectures for smart factories by elegantly and cost effectively leveraging a distributed network of computing nodes spread across the enterprise. Developed by Ocado Technology, a division of Ocado (the world's largest online-only supermarket), the Kubermesh package uses container-based technology and the Kubernetes system to implement an on-premises private cloud architecture in which desktop computers can be configured as nodes supporting the compute or storage functionality typically delivered by high-performance servers in a data center.

  • DH2i Embraces Linux Containers as Enterprise Market Evolves

    DH2i is adding support for Linux-based containers to its traditionally Windows-centric container management platform, citing increased demand from enterprise customers.

    The company’s software is basically a container-as-a-service (CaaS) platform that now includes support for a broader range of container hosts. That expanded platform uses a unified interface to support various Linux-based permutations along with Microsoft container services.

  • Power Use, RAM + Boot Times With Unity, Xfce, GNOME, LXDE, Budgie & KDE Plasma

    One of the first follow-on requests from this morning's Razer Blade Stealth Linux testing was for on top of all the other data-sets shared in that article to also look at the RAM usage, battery power draw, and boot times for the different desktop options on Ubuntu 17.04. As the request came in from a Phoronix Premium supporter, I jumped on that and here are some of those numbers.

  • The Linux Foundation Announces 18 New Silver Members

    The Linux Foundation, the nonprofit organization enabling mass innovation through open source, announced that 18 new organizations have joined the Foundation as Silver members. Linux Foundation members help support development of the greatest shared technology resources in history, while accelerating their own innovation through open source leadership and participation.

  • How People Collaborate on Linux Kernel Mailing Lists

    Linux is one of the largest and most successful open source projects in history.  According to a 2016 report from The Linux Foundation, more than 13,500 developers from more than 1,300 companies have contributed to the Linux kernel since tracking began 11 years ago.

    At Open Source Summit in Los Angeles, Dawn Foster, a part-time consultant at The Scale Factory and a PhD student at the University of Greenwich in London, will share her research into how these many developers and contributors collaborate on the Linux kernel mailing lists, including network visualizations of mailing list interactions between contributors.

  • Learn more about distributed databases with ShardingSphere

    Apache ShardingSphere is an open source distributed database, plus an ecosystem users and developers need for their database to provide a customized and cloud-native experience. In the three years since it joined the Apache Foundation, the ShardingSphere core team has worked hard with the community to create an open source, robust, and distributed database and a supporting ecosystem. ShardingSphere doesn't quite fit into the usual industry mold of a simple distributed database middleware solution. ShardingSphere recreates the distributed pluggable system, enabling actual user implementation scenarios to thrive and contributing valuable solutions to the community and the database industry.

Programming Leftovers

  • Cracking the Spotify Code

    Spotify offers a little picture that, when scanned, opens almost anything searchable with Spotify. Several lines are centered on the Spotify logo with eight different heights, storing information in octal. Many visual encoding schemes encode some URI (Uniform Resource Identifier) that provides a unique identifier for that specific song, album, or artist when decoded. Since many URIs on Spotify are pretty long (one example being spotify :show:3NRV0mhZa8xeRT0EyLPaIp which clocks in at 218 bits), some mechanism is needed to compress the URIs down to something more manageable. Enter the media reference, a short sequence encoding a specific URI, generally under 40 bits. The reference is just a lookup in a database that Spotify maintains, so it requires a network connection to resolve. The actual encoding scheme from media reference to the values in the bars is quite complex involving CRC, convolution, and puncturing. The CRC allows the program to check for correct decoding, and the convolution enables the program to have a small number of read errors while still having an accurate result. Puncturing is just removing bits to reduce the numbers encoded, relying on convolution to fill in the holes.

  • Day 7: Neural Nets in Raku (Part 1) – Raku Advent Calendar

    Thinky the Elf was sitting in his office, it had been a closet but he’d been given it as his office after the great baked beans incident. It wasn’t his fault. He was right that feeding the reindeer beans would give them a jet boost but Santa had not been all that happy about it. And his tendency to stare of into space while suddenly having a thought wasn’t great while working on the shop floor meant it was safer to put him out of the way to do some thinking. Recently he’d been thinking about how to sort children into naughty or nice. This was Santa’s big job all year and Thinky thought that there must be a way to simplify it, he’d spent some time watching videos on YouTube and there was one that gave a brilliant description of Neural Networks (jump to 20 minutes for that bit but it’s an interesting video). As Thinky watched this he couldn’t help thinking about Raku and how the connections between nodes felt like Supplies.

  • Rblpapi 0.3.12: Fixes and Updates

  • LLVM Now Has "Official" Support For Targeting NEC's Vector Engine (VE) - Phoronix

    The LLVM compiler infrastructure supports not only a growing number of CPU architectures but continues to lead when it comes to its support for different accelerators. Back in 2019 NEC was working to upstream their SX-Aurora VE "Vector Engine" Accelerator and now as of this week that target is considered officially supported upstream. NEC originally launched the SX-Aurora Vector Engine (VE) back in 2018 as a PCI Express accelerator card and supporting up to eight vector processors per server. The NEC SX-Aurora has its own architecture for the "VE" and is backed by HBM2 memory. The current VE processor is rated for 1.53 TB/s of memory bandwidth and a double precision peak performance of 3.07 TFLOPS or 4.91 single precision TFLOPS.

  • 5 Excellent Free Books to Learn CSS - LinuxLinks

    Web pages are built with HTML, which specifies the content of a page. CSS (Cascading Style Sheets) is a separate language which specifies a page’s appearance. CSS code is made of static rules. Each rule takes one or more selectors and gives specific values to a number of visual properties. Those properties are then applied to the page elements indicated by the selectors. Here’s our recommended books to learn CSS.

SSH Key Rotation with the POSIX Shell - Sunset Nears for Elderly Keys

OpenBSD has recently stressed to us the value of key rotation by their use of “Signify” distribution release signatures. We have realized that SSH keys should also rotate, to reduce the risk of powerful keys that fall into the wrong hands which become “the gift that keeps on giving.” There have always been open questions on the retirement of SSH keys. These questions have grown in volume and many are joining the advocacy for SSH certificate authorities. To “rotate” an SSH key is to replace it, in such a way that it is no longer recognized, requiring removal from the authorized_keys file. SSH rotation is commonly addressed with Ansible, but this leaves many users on smaller systems or lacking privilege without recourse. A more basic and accessible method to migrate SSH keys is sorely lacking. Below is presented an SSH key rotation script written in nothing more than the POSIX shell. There is palpable danger in the misuse of such a tool. Many administrators control inaccessible systems that entail massive inconvenience in a loss of control. Demonstrated here are rotation schemes of increasing risk, for any holder of a key to choose, to their own tolerance. Hopefully, I have not made grave mistakes in the design. The most conservative users of this approach should tread with extreme caution, test carefully, and ensure alternate means of access prior to any deployment. As the author, I have no desire to assume any responsibility for a failed rotation, and its consequences. I especially disavow the “wipe” option below to remove entries from authorized_keys. It is presented as commentary, not working code. In any case, we foolishly rush in where the more prudent fear to tread. Read more
