  • AArch64 desktop hardware?

    Soon there will be four years since I started working on AArch64 architecture. Lot of software things changed during that time. Lot in a hardware too. But machines availability still sucks badly.

    In 2012 all we had was software model. It was slow, terribly slow. Common joke was AArch64 developers standing in a queue for 10GHz x86-64 cpus. So I was generating working binaries by using cross compilation. But many distributions only do native builds. In models. Imagine Qt4 building for 3-4 days…

    In 2013 I got access to first server hardware. With first silicon version of CPU. Highly unstable, we could use just one core etc. GCC was crashing like hell but we managed to get stable build results from it. Qt4 was building in few hours now.

  • RISC-V on an FPGA, pt. 1

    Last year I had open source instruction set RISC-V running Linux emulated in qemu. However to really get into the architecture, and restore my very rusty FPGA skills, wouldn’t it be fun to have RISC-V working in real hardware.

    The world of RISC-V is pretty confusing for outsiders. There are a bunch of affiliated companies, researchers who are producing actual silicon (nothing you can buy of course), and the affiliated(?) lowRISC project which is trying to produce a fully open source chip. I’m starting with lowRISC since they have three iterations of a design that you can install on reasonably cheap FPGA development boards like the one above. (I’m going to try to install “Untether 0.2” which is the second iteration of their FPGA design.)

  • California dreaming: DIY, open-source SoCs with RISC-V

    With its customizable, open-source SoCs built on the free and open RISC-V instruction set architecture, SiFive, a San Francisco start-up, is poised to reverse the industry’s rising licensing, design and implementation costs.

    With on the one hand Moore’s Law ended or approaching the end and on the other, vast investments required for to develop a modern, high-performance chip, it looks impossible for smaller system designers to join the traditional economic model of chip building. However, the body of software and tools available from the open-source community under the guidance of the RISC-V Foundation, can substantially cut the cost of developing custom silicon. System designers can use the SiFive Freedom platforms to focus on their own differentiated processor without having the overhead of developing a modern SoC, fabric or software infrastructur

  • Lawn Da Vinci Open Source RC Lawnmower (video)

    If you find the prices of the current range of robotic lawnmowers just a little too high for your budget, you might be interested in a new open source remote control lawnmower which has been created called the Lawn Da Vinci.

    Okay so it’s not completely autonomous but you can still add a little extra fun to those lawn mowing days, with the addition of a little remote control to the humble petrol powered lawnmower.

  • A open source toolkit for building your own home

    The evidence is overwhelming that large scale collaboration leads to superior technology. FOSS showed us the way and now free and open source hardware is rapidly gaining traction.

  • Smaller & Faster than Raspberry Pi Zero: Meet NanoPi NEO ARM Linux Development Board

    Raspberry Pi Zero has two noticeable attributes compared to other Raspberry Pi boards: it’s smaller and it’s cheaper. FriendlyARM has now designed another model for their NanoPi family, that about 12% smaller, although not quite as thin at all due to its Ethernet jack and USB connector, and much faster than Raspberry Pi Zero, with NanoPi NEO board powered by Allwinner H3 quad core processor.

  • 8 open source point of sale systems

    Running a small business isn't easy, and especially so for retailers, restaurant owners, and others who have a brick-and-mortar storefront.

    In his recent ELC talk, ARM kernel developer Mark Rutland traced the evolution of caches over the last decade or so, and explained how to manage them.

Despite this warning, Rutland’s presentation, titled Embedded Linux Conference presentation titled Stale Data, or How We (Mis-)manage Modern Caches, was actually kind of an eye opener — at least as far as cache management presentations go.

  • This open source CNC system integrates high-tech automation into backyard farming

    This story might more properly belong on RobotHugger, but with its open source DIY approach to small-scale food production, FarmBot is worth a look.

    The old-school gardener in me is battling my high-tech early adopter side over whether or not this robotic farming device is a step toward greater food sovereignty or toward a dystopian future where robot overlords rule backyard farms. Sure, it's easy enough to learn to garden the old fashioned way, on your hands and knees with your hands in the soil, but considering that one of the excuses for not growing some our own food is lack of time and lack of skills and knowledge, perhaps this automated and optimized small-scale farming approach could be a feasible solution for the techie foodies who would like homegrown food without having to have a green thumb.

  • Tropical Labs Offers a Powerful Open Source Servo for Makers

    Joe Church from Tropical Labs wanted low cost, accurate servo motors for a project but was unable to find the right parts for his need.

The motor project eventually turned into Mechaduino, and Tropical Labs is running a highly successful Kickstarter campaign to fund the first run of production motors.

  • SiFive – the open-source hardware company

    Customisation periods end with ICs becoming complex and expensive and, at that point, standardisation comes in and returns ICs to affordability.

    Or that’s the theory.

    Over the years there have been many ways to bring the cost of custom silicon down – MPW, ASIC, P-SOC, FPGAs and, latterly, ARM’s offer of free access to Cortex-M0 processor IP through DesignStart which aims to deliver test chips for $16,000.

  • Inside Japan’s Future Exascale ARM Supercomputer

    The rumors that supercomputer maker Fujitsu would be dropping the Sparc architecture and moving to ARM cores for its next generation of supercomputers have been going around since last fall, and at the International Supercomputing Conference in Frankfurt, Germany this week, officials at the server maker and RIKEN, the research and development arm of the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT) that currently houses the mighty K supercomputer, confirmed that this is indeed true.

  • Intel: ARM Servers To Renew Their Attack

    Up until now, server chips based on ARM Holdings' (NASDAQ:ARMH) architecture have had little impact on the data center market, and Intel's (NASDAQ:INTC) Data Center Group has continued to grow. ARM server vendors are preparing the next wave of server chips based on 14-16 nm FinFET technology. These will be much more competitive and energy efficient and could start to erode Intel's share of the data center by 2017.

  • Will Open-Source Work For Chips?

    The open source movement, as we know it today, started in the 1980s with the launch of the GNU project, which was about the time the electronic design automation (EDA) industry was coming into existence. EDA software is used to take high-level logical descriptions of circuits and map them into silicon for manufacturing. EDA software starts in the five digits, even for the simplest of tools, tacking on two or three zeros for a suite of tools necessary to fully process a design. On top of this, manufacturing costs start at several million dollars.

    What if your next house were to cost 1/10th of the average home while sporting a long list of high-tech hyper-ecological features? With the help of the Open Building Institute (OBI), which is designing affordable, ecological housing accessible to everyone - you may be able to do just that.

    [...]

    OBI is following the same open source methodology that has made the Internet so successful --- sharing the source code with a free license. Google and Facebook and many other Internet companies use open source software on the backend because large scale collaboration generally leads to superior technology. Open source hardware follows the same approach from electronics to 3-D printers.

The 64-bit Raspberry Pi 3 has topped a poll of 81 single-board Linux and Android systems among Linux folk.

The 2016 Single Board Computer (SBC) Survey saw the Raspberry Pi 3 slide into the number one slot ahead of the Odroid-C2 and BeagleBone.

A Raspberry Pi 2 topped the SBC poll in 2015, only this time organisers reckoned this year's Pi blew away the number two player by an even greater margin.

The Raspberry Pi 3 got a score of 387, versus 227 for the Ordroid-C2 and 191 for the BeagleBone Black in a poll of 473 people, carried out according to a proportional representation system. Boards had to run Linux-based distributions, including Android, and be priced at less than $200.

    Brillo, he said, is a software stack for the Internet of things based on the Android system. These deployments bring a number of challenges, starting with the need to support a different sort of hardware than Android normally runs on; target devices may have no display or input devices, but might well have "fun buses" to drive interesting peripherals. The mix of vendors interested in this area is different; handset vendors are present, but many more traditional embedded vendors can also be found there. Brillo is still in an early state of development.
  • Reviewing Project Management Service `Wrike` And Seems Interesting
    I have been testing some services for our project and found this amazing service, thought why not share it with you guys, it might be useful for you. Project management is a term that in some respects appears common, yet in practice still seems to be limited to large companies. While this may be true, the foundations of project management are actually rather simple and can be adopted by anyone, in any industry. One of the major requirements you need to consider when selecting a good project management software is the ability to run and operate it on the go via your mobile devices. Other factors include the ability to access the software from any platform whether it be Linux, Mac, or Windows. This can be achieved when the project management software is web-based. Wrike is a software that does of all this.

    For those who can't live without screen colour shifting technology such as Redshift or f.lux, myself being one of them, using Wayland did pose the challenge of having these existing tools not working with the Xorg replacement. Thankfully, all is not lost and it is possible even right now. Thanks to a copr repo, it's particularly easy on Fedora 25. One of the changes that comes with Wayland is there is currently no way for third-party apps to modify screen gamma curves. Therefore, no redshift apps, such as Redshift itself (which I recently covered here) will work while running under Wayland.
