  • C.H.I.P. – Not A Replacement For Beast, But A Useful Controller Board

    I’ve been looking for an ARMed replacement for Beast’s power-sucking/fanfull/large corpse. This isn’t it. It is a very well documented controller that ships with a minimal installation of Debian GNU/Linux complete with GUI. I could, for instance, use this thing to make a pulsewidth modulator for a power supply. It’s obviously overkill for such a task but at the advertised price, $9, it’s OK.

  • Make a $40 Linux or Android PC with new Raspberry Pi 2 rival

    If you want to build a powerful $40 Linux or Android PC with 4K video support, consider Hardkernel's Odroid-C2 computer.

    The developer board is an uncased computer like the popular Raspberry Pi 2, which sells for $35. But South Korea-based Hardkernel claims Odroid-C2 has more horsepower than its popular rival and can be a desktop replacement.

  • Telecoms Look Past Cisco and HP to Open Source Hardware

    Now, a new wave of companies aims to push this movement even further. This morning, four big-name telecoms— AT&T, Verizon, Germany’s Deutsche Telekom, and South Korea’s SK Telecom—agreed to join the Open Compute Project. Through a sub-project dedicated to the needs of telecoms, they too will explore open source servers and networking equipment that can boost efficiency and reduce costs. “Everyone is looking for that same synergy and agility,” Gagan Puranik, a director of architecture planning at Verizon, says of his company and others who have joined Facebook’s experiment in open source hardware. “The learning and the sharing will go both ways.”

  • Large Telcos Flock to Facebook's Open Compute Project, Open Hardware [Ed: not code]

    According to Facebook's published guidelines, the new OCP Telco Project will advance the following objectives: 1) communicating telco technical requirements effectively to the OCP community; 2) strengthening the OCP ecosystem to address the deployment and operational needs of telcos; and 3) bringing OCP innovations to telco data center infrastructure for increased cost-savings and agility.

A Massive ARM v6/v7 Rework Is Landing With Linux 4.5 Plus Raspberry Pi 2 Support

Filed under

Olof Johansson sent in all of the ARM SoC updates for the Linux 4.5 merge window on Friday night. Most significant is the ARM multi-platform code update. Olof explained, "This branch is the culmination of 5 years of effort to bring the ARMv6 and ARMv7 platforms together such that they can all be enabled and boot the same kernel. It has been a tremendous amount of cleanup and refactoring by a huge number of people, and creation of several new (and major) subsystems to better abstract out all the platform details in an appropriate manner. The bulk of this branch is a large patchset from Arnd that brings several of the more minor and older platforms we have closer to multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview Much of this is moving around header files from old mach directories, but there are also some cleanup patches of debug_ll (lowlevel debug per-platform options) and other parts."

  • Wintel Is Sick

    There isn’t any end in sight. As ARM and particularly ARM on mobile devices grows Wintel is being squeezed out of personal IT. Long ago, I and many others cut out That Other OS. Now many millions, billions even, are cutting out Intel. Both heads of the Wintel monopoly are diversifying as fast as they can and cutting prices or moving “profit centers” to avoid being trapped under the weight of their own handiwork. The world just doesn’t need either any longer but it does take a few years to switch over so much installed base of IT. It’s a process, not an event, just like sickness. It remains to be seen whether this is a mortal wounding or just an injury both can survive. I expect that both will survive but both will be cut down to size and only get a normal share of the pie instead of the whole thing.

  • Opportunities And Challenges That The Internet Of Things Creates

    Internet of Things is targeting not only devices, but also sensors. It’s incredible how they can be attached everywhere and record necessary data. For example, wearables are collecting data about fitness habits of their owners and this helps to update the devices with more attention paid to the functionality in high demand. Or, for example, network-connected sensors are used to inform farmers about the pregnancy and sickness of animals. Just imagine if your coffee cup could know how hot you want your coffee to be and how much sugar or milk you add. Collected data would allow businesses to get more specific information on how their products are used, how they break down and what is expected from them in the future.

  • Google, HP, Oracle Join RISC-V

    RISC-V is on the march as an open source alternative to ARM and Mips. Fifteen sponsors, including a handful of high tech giants, are queuing up to be the first members of its new trade group which will host next week its third workshop for the processor core.

    RISC V is the latest evolution of the original RISC core developed more than 25 years ago by Berkeley’s David Patterson and Stanford’s John Hennessey. In August 2014, Patterson and colleagues launched an open source effort around the core as an enabler for a new class of processors and SoCs with small teams and volumes that can’t afford licensed cores or get the attention of their vendors.

  • An Open Source Reference Architecture For Real-Time Stock Prediction

    While this post does not cover the details of stock analysis, it does propose a way to solve the hard problem of real-time data analysis at scale, using open source tools in a highly scalable and extensible reference architecture. The architecture below is focused on financial trading, but it also applies to real-time use cases across virtually every industry. More information on the architecture covered in this article is also available online via The Linux Foundation, Slideshare, YouTube, and Pivotal Open Source Hub, where the components in this architecture can be downloaded.

  • Open-Source Tessellation Lands For Pre-Broadwell Intel Hardware

    Back on Christmas was news of patches for implementing tessellation shader support for Intel Ivy Bridge and Haswell graphics hardware after support had already landed for Broadwell and newer within the Mesa driver. Support for those older generations is now present in Mesa.

    As of this afternoon, Kenneth Graunke's work for implementing GL_ARB_tessellation_shader support for Ivy Bridge and Haswell is now within Mesa Git master. This makes tessellation support implemented for all hardware capable of doing so -- Sandy Bridge and older are not.

10 more Raspberry Pi projects primed for IT

Filed under

The Raspberry Pi was created as an educational platform but has become one of the most popular embedded systems platforms on earth with a full copy of Linux and a rabid community of DIY-minded developers. That combination alone makes the Raspberry Pi a natural fit for hacking together enterprise IT applications and devices. Add in its low cost and the ready availability of open source solutions, and you can quickly see how previously expensive systems and devices are suddenly within reach of IT departments willing to experiment with Raspberry Pi, as my first foray into DIY IT Raspberry Pi projects showed.

  • 4 Useful Cinnamon Desktop Applets
    The Cinnamon desktop environment is incredibly popular, and for good reason. Out of the box it offers a clean, fast and well configured desktop experience. But that doesn’t mean that you can’t make it a little better with a few nifty extras. And that’s where Cinnamon Applets come in. Like Unity’s Indicator Applets and GNOME Extensions, Cinnamon Applets let you add additional functionality to your desktop quickly and easily.
  • GNOME Core Apps Hackfest
    The hackfest is aimed to raise the standard of the overall core experience in GNOME, this includes the core apps like Documents, Files, Music, Photos and Videos, etc. In particular, we want to identify missing features and sore points that needs to be addressed and the interaction between apps and the desktop. Making the core apps push beyond the limits of the framework and making them excellent will not only be helpful for the GNOME desktop experience, but also for 3rd party apps, where we will implement what they are missing and also serve as an example of what an app could be.

Onchain provides the bottom-layer framework for Ali Cloud, including its open-source blockchain capabilities, to enable any company to customize its own enterprise-level blockchain.
  • Netflix on Firefox for Linux
    If you're a Firefox user and you're a little fed up with going to Google Chrome every time in order to watch Netflix on your Linux machine, the good news is since Firefox 49 landed, HTML5 DRM (through the Google Widevine CDM (Content Decryption Manager) plugin) is now supported. Services that use DRM for HTML5 media should now just work, such as Amazon Prime Video. Unfortunately, the Netflix crew haven't 'flicked a switch' yet behind the scenes for Firefox on Linux, meaning if you run Netflix in the Mozilla browser at the moment, you'll likely just come across the old Silverlight error page. But there is a workaround. For some reason, Netflix still expects Silverlight when it detects the user is running Firefox, despite the fact that the latest Firefox builds for Linux now support the HTML5 DRM plugin.

  • How open access content helps fuel growth in Indian-language Wikipedias
    Mobile Internet connectivity is growing rapidly in rural India, and because most Internet users are more comfortable in their native languages, websites producing content in Indian languages are going to drive this growth. In a country like India in which only a handful of journals are available in Indian languages, open access to research and educational resources is hugely important for populating content for the various Indian language Wikipedias.
  • Where to find the world's best programmers
    One source of data about programmers' skills is HackerRank, a company that poses programming challenges to a community of more than a million coders and also offers recruitment services to businesses. Using information about how successful coders from different countries are at solving problems across a wide range of domains (such as "algorithms" or "data structures" or specific languages such as C++ or Java), HackerRank's data suggests that, overall, the best developers come from China, followed closely by Russia. Alarmingly, and perhaps unexpectedly, the United States comes in at 28th place.

As we've reported before, tools that demystify and function as useful front-ends and connectors for the open source Hadoop project are much in demand. AtScale, billed as “the first company to allow business users to do business intelligence on Hadoop,” focused its study on the strengths and weaknesses of the industry’s most popular analytical engines for Hadoop – Impala, SparkSQL, Hive and Presto.
  • Study Says OpenStack at Scale Can Produce Surprising Savings
    Revenues from OpenStack-based businesses are poised to grow by 35 percent a year to more than $5 billion by 2020, according to analysts at 451 Research. In its latest Cloud Price Index, 451 Research analyzes the costs associated with using various cloud options to determine when it becomes better value to use a self-managed private cloud instead of public or managed cloud services. The idea is to createa complex pricing model that takes into consideration the major factors impacting total cost of ownership (TCO), including salaries and workload requirements.The 451 study found that because of the prevalence of suitably qualified administrators, commercial private cloud offerings such as VMware and Microsoft currently offer a lower TCO when labor efficiency is below 400 virtual machines managed per engineer. But where labor efficiency is greater than this, OpenStack becomes more financially attractive. In fact, past this tipping point, all private cloud options are cheaper than both public cloud and managed private cloud options.
  • How OpenStack mentoring breaks down cultural barriers
