  • Cybersecurity education isn't good, nobody is shocked

    There was a news story published last week about the almost total lack of cybersecurity attention in undergraduate education. Most people in the security industry won't be surprised by this. In the majority of cases when the security folks have to talk to developers, there is a clear lack of understanding about security.

  • Making it easier to deploy TPMTOTP on non-EFI systems

    On EFI systems you can handle this by sticking the secret in an EFI variable (there's some special-casing in the code to deal with the additional metadata on the front of things you read out of efivarfs). But that's not terribly useful if you're not on an EFI system. Thankfully, there's a way around this. TPMs have a small quantity of nvram built into them, so we can stick the secret there. If you pass the -n argument to sealdata, that'll happen. The unseal apps will attempt to pull the secret out of nvram before falling back to looking for a file, so things should just magically work.

  • 6 steps to calculate ROI for an open hardware project

    Free and open source software advocates have courageously blazed a trail that is now being followed by those interested in open source for physical objects. It's called free and open source hardware (FOSH), and we're seeing an exponential rise in the number of free designs for hardware released under opensource licenses, Creative Commons licenses,or placed in the public domain.

  • First Open Source GPU Could Change Future of Computing

    Nyami is significant in the research, computing and open source communities because it marks the first time open source has been used to design a GPU, as well as the first time a research team was able to test how different hardware and software configurations affect GPU performance. The results of the experiments the researchers performed are now part of the open source community, and that work will help others follow in the original research team’s footsteps. According to Timothy Miller, a computer science assistant professor at Binghamton, as others create their own GPUs using open source, it will push computing power to the next level.

  • We are happy to share our FREE and OPEN-SOURCE microprocessor system PULPino!

    Not a toy design: PULPino is a mature design: it has been taped-out as an ASIC in UMC 65nm in January 2016. The PULPino platform is available for RTL simulation as well for FPGA mapping. It has full debug support on all targets. In addition we support extended profiling with source code annotated execution times through KCacheGrind in RTL simulations.

    And it is free, no registration, no strings attached, you can use it, change it, adapt it, add to your own chip, use it for classes, research, projects, products… We just ask you to acknowledge the source, and if possible, let us know what you like and what you like and don’t like.

  • Wiring was Arduino before Arduino

    Hernando Barragán is the grandfather of Arduino of whom you’ve never heard. And after years now of being basically silent on the issue of attribution, he’s decided to get some of his grudges off his chest and clear the air around Wiring and Arduino. It’s a long read, and at times a little bitter, but if you’ve been following the development of the Arduino vs Arduino debacle, it’s an important piece in the puzzle.

  • Open Source Hardware is an opportunity for Synthetic Biology research – the DocuBricks approach by Tobias Wenzel

    There is a lesson to be learned from the incompleteness of commercial assembly-set documentations: Open Source Hardware is more than an assembly instruction. It is also about documenting design files and decisions along its functionality and in a modular fashion, complete with testing and calibration instructions. A good documentation enables the project to grow and improve without the doing of the inventor. Only in this way most projects can enfold their benefit well to society and technology companies. To be sure, documenting a hardware project is not easy and requires time. For this reason a handful scientists at the University of Cambridge (including the author), all with a background in technology and biology, recently started the DocuBricks initiative. DocuBricks is an open source and free software that makes documenting hardware and usage procedures easier. The name is a reference to modularity in the same way as Lego or BioBricks. As the name suggests, the editor part of the software guides the user through a modular documentation structure with relevant fields in a standardised, yet general format. The user can create a hierarchy of documentation bricks, explaining their function, implementation and assembly while referring to a parts library. The result is a XML document and a folder with construction and media files that is displayed with the viewer part of the software (a style sheet and script to enable interactivity).

  • Kicad hacking - Intra-sheet links and ERC

    I spent time looking at gEDA and Eagle when I wanted to get back into hardware hacking for my own ends; but neither did I really click with. On the other hand, a mere 10 minutes with Kicad and I knew I had found the tool I wanted to work with long-term.

  • Open-Source System 3D Prints from Custom Powders

    An open-source laser sintering printer has been used to print intricate 3D objects from powdered plastics and biomaterials. The system costs a fraction of equivalent commercial systems and could give researchers a DIY technique for working with their own specialized materials.

  • Raspberry Pi 3 on sale now at $35

    Exactly four years ago, on 29 February 2012, we unleashed the original 256MB Raspberry Pi Model B on a largely unsuspecting world. Since then, we’ve shipped over eight million units, including three million units of Raspberry Pi 2, making us the UK’s all-time best-selling computer. The Raspberry Pi Foundation has grown from a handful of volunteers to have over sixty full-time employees, including our new friends from Code Club. We’ve sent a Raspberry Pi to the International Space Station and are training teachers around the world through our Picademy program.

  • Raspberry Pi 3 has Wi-Fi and Bluetooth, 64-bit chip, still just $35

    The third major version of the Raspberry Pi will go on sale Monday, with the $35/£30 credit card-sized Raspberry Pi 3 Model B now sporting a 64-bit processor and embedded Wi-Fi and Bluetooth.

    In previous versions, the Pi needed USB adapters to get Wi-Fi and Bluetooth connectivity. Raspberry Pi 3 supports 802.11n Wi-Fi (2.4GHz only) and Bluetooth 4.0 without an adapter, freeing up its four USB ports for other purposes.

  • Raspberry Pi 3 with 64-bit quad-core SoC, built-in Wi-Fi and Bluetooth announced for $35

    Months after introducing its most affordable Raspberry Pi Zero, the company has introduced the Raspberry Pi 3, successor of the Raspberry Pi 2 that was introduced back in February last year. Even though it is in the same size and has much of the same components on board as the Pi 2, the new Pi 3 has a faster 64-bit quad-core Broadcom BCM2837 SoC with ARM Cortex-A53 CPU, has built-in Wi-Fi 802.11n and Bluetooth 4.1.Months after introducing its most affordable Raspberry Pi Zero, the company has introduced the Raspberry Pi 3, successor of the Raspberry Pi 2 that was introduced back in February last year.

  • 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.

From Raspberry Pi to Supercomputers to the Cloud: The Linux Operating System

Linux is widely used in corporations now as the basis for everything from file servers to web servers to network security servers. The no-cost as well as commercial availability of distributions makes it an obvious choice in many scenarios. Distributions of Linux now power machines as small as the tiny Raspberry Pi to the largest supercomputers in the world. There is a wide variety of minimal and security hardened distributions, some of them designed for GPU workloads. Read more

IBM’s Systems With GNU/Linux

  • IBM Gives Power Systems Rebates For Linux Workloads
    Big Blue has made no secret whatsoever that it wants to ride the Linux wave up with the Power Systems platform, and its marketeers are doing what they can to sweeten the hardware deals as best they can without adversely affecting the top and bottom line at IBM in general and the Power Systems division in particular to help that Linux cause along.
  • Drilling Down Into IBM’s System Group
    The most obvious thing is that IBM’s revenues and profits continue to shrink, but the downside is getting smaller and smaller, and we think that IBM’s core systems business will start to level out this year and maybe even grow by the third or fourth quarter, depending on when Power9-based Power Systems and z14-based System z mainframes hit the market. In the final period of 2016, IBM’s overall revenues were $21.77 billion, down 1.1 percent from a year ago, and net income rose by nearly a point to $4.5 billion. This is sure a lot better than a year ago, when IBM’s revenues fell by 8.4 percent to $22 billion and its net income fell by 18.6 percent to $4.46 billion. For the full 2016 year, IBM’s revenues were off 2.1 percent to $79.85 billion, but its “real” systems business, which includes servers, storage, switching, systems software, databases, transaction monitors, and tech support and financing for its own iron, fell by 8.3 percent to $26.1 billion. (That’s our estimate; IBM does not break out sales this way, but we have some pretty good guesses on how it all breaks down.)
