  • Retrocomputing With Open Source FPGAs

    A few years ago, we saw the reverse engineering of the Lattice iCE40 bitstream, opening the door to a completely Open Source development tool chain for FPGAs. This was an astonishing amount of work from [Clifford Wolf], [Mathias Lasser], and [Cotton Seed], but since then we haven’t seen a whole lot from Project IceStorm. Now, that’s about to change, and in the coolest way possible. [hoglet] is retrocomputing on an ICE40 development board.

    This is an implementation of the Acorn Atom on a myStorm BlackIce board. This board is basically just a Lattice iCE40 FPGA, a few support components, and a bunch of pin headers, some of which are in the not-so-handy Arduino pinout footprint. By porting some Acorn Atom implementations and a 6502 core to verilog, [hoglet] was able to stuff a cool old retrocomputer onto an Open Source FPGA development board. Video output is through a resistor DAC driving a VGA cable, and keyboard input is through PS/2.

Survey shows Linux and FreeRTOS out front in embedded tech

Filed under
Linux
Hardware

AspenCore’s 2017 survey of embedded tech developers reveals that open source OSes like Linux and FreeRTOS continue to grow as proprietary platforms decline.

Dozens of market studies are happy to tell you how many IoT gizmos are expected to ship by 2020, but few research firms regularly dig into embedded development trends. That’s where reader surveys come in handy. Our own joint survey with Linux.com readers on hacker board trends offer insights into users of Linux and Android community-backed SBCs. The AspenCore survey of its EETimes and Embedded readers has a smaller sample (1,234 vs. 1,705), but is broader and more in depth, asking many more questions and spanning developers who use a range of OSes on both MCU and application processors.

The survey, which was taken in March and April of this year, does not perfectly represent global trends. The respondents are predominantly located in the U.S. and Canada (56 percent) followed by Europe/ENEA (25 percent), and Asia (11 percent). They also tend to be older, with an average of 24 years out of college, and work at larger, established companies with an average size of 3,452 employees and on teams averaging 15 engineers.

  • Keeping The Ryzen Threadripper Busy With An Array Of Compiler Benchmarks

    While there are an array of interesting AMD Ryzen Threadripper 1950X Linux benchmarks in this morning's review, after hitting a 36 second Linux kernel compilation time with this 16 core / 32 thread processor, I spent this afternoon seeing what I was getting for some other compile times of popular programs.

  • AMD Replaces Ryzen CPUs for Users Affected By Rare Linux Bug

    AMD’s Ryzen 7 has been generally well-received by the enthusiast community, but there’s been one low-level problem that we’ve been watching but haven’t previously reported on. In early June, Ryzen users running Linux began reporting segmentation faults when running multiple concurrent compilation workloads using multiple different versions of GCC. LVVM/Clang was not affected, and the issue appears confined to Linux. Moreover, it wasn’t apparently common, even among Linux users — Michael Larabel, of Phoronix.com, reported that his own test rigs had been absolutely solid, even under heavy workloads.

    Like the Pentium FDIV bug of yesteryear, this was a real issue, but one that realistically only impacted a fraction of a fraction of buyers. AMD had previously said it was investigating the problem (which isn’t present on any Epyc or Threadripper CPUs) and it’s now announced a solution: CPU replacement.

  • New York City cops will replace their 36,000 Windows phones with iPhones
  • New York Police scrap 36,000 Windows smartphones

    The New York Police Department will scrap 36,000 smartphones, thanks to a monumental purchasing cock-up by a billionaire's daughter.

    The city spent millions on the phones back in October 2016 as part of its drive to bring the police force into the 21st century. And the woman behind the purchase – Deputy Commissioner for Information Technology, Jessica Tisch – praised them for their ability to quickly send 911 alerts to officers close to an incident.

    There was only one problem: Tisch chose Windows-based Lumia 830 and Lumia 640 XL phones, and Microsoft officially ended support for Windows 8.1 in July.

  • Purism's Librem 5 Is Nearing $100k In Funding, But A Long Journey Remains

    This week Purism announced their plans for the Librem 5 smart-phone as a GNU/Linux smartphone that is privacy-respecting, as open as possible, and costs $599 USD. The company believes they can have the phone ready for release by early 2019 if they raise $1.5 million USD over the next two months. In just about three days they have raised nearly $100,000, but it's not clear if the pacing will continue to reach the milestone in time.

    As of writing this morning, they have raised $93,994 USD since their announcement on Thursday. This includes 134 backers sending in $599 USD to effectively pre-order the device, just six sending in $299 USD for the developer kit, two sending in $1399 for getting the Librem 5 phone with a 24-inch monitor, and four pledging $1699 USD to get the Librem 5 phone with an unnamed 30-inch monitor.

  • The Librem 5: Your Ultimate GNU/Linux FLOSS Smartphone

    Purism is well known for Linux based laptop with Coreboot. Now they started a crowdfunding campaign today for its smartphone called Purism Librem 5. What is so special about this phone? It is 100% powered by GNU/Linux. You can run any Linux distro on it. The phone provides high security and privacy features, i.e., it does not track you. This seems like an excellent device. One that I would certainly purchase or recommend to a privacy-conscious person.

  • The Librem 5 from Purism: A Matrix Native Smartphone.

    We’ve been approached by Purism to partner up to provide the communications subsystem for their upcoming Librem 5 smartphone – for which they are launching a crowdfunding campaign starting today! The whole idea of the phone is to provide unprecedented privacy, security and autonomy by running an entirely FOSS Debian-based GNU/Linux stack (even including CPU & GPU drivers!), and we are incredibly proud and overexcited that the folks at Purism have asked the Matrix core team to provide the native dialler and messaging app for the phone.  Yes, this means that the phone will literally boot by default into Matrix for all its primary communications (although, being FOSS, you could of course use a different dialler if you wanted).  The intention is to be a very usable and flexible phone for folks who value freedom, privacy and simplicity over the (relative) quagmire of iOS or Android – and of course jumping way ahead of where Apple or Google are in terms of integrating next-generation communications into the very heart of the device.

Fedora: Fedora Workstation and Fedora Council

  • Looking back at Fedora Workstation so far
    So I have over the last few years blogged regularly about upcoming features in Fedora Workstation. Well I thought as we putting the finishing touches on Fedora Workstation 27 I should try to look back at everything we have achieved since Fedora Workstation was launched with Fedora 21. The efforts I highlight here are efforts where we have done significant or most development. There are of course a lot of other big changes that has happened over the last few years by the wider community that we leveraged and offer in Fedora Workstation, examples here include things like Meson and Rust. This post is not about those, but that said I do want to write a post just talking about the achievements of the wider community at some point, because they are very important and crucial too. And along the same line this post will not be speaking about the large number of improvements and bugfixes that we contributed to a long list of projects, like to GNOME itself. This blog is about taking stock and taking some pride in what we achieved so far and major hurdles we past on our way to improving the Linux desktop experience.
  • Resigning from Fedora Council for Fedora 27
    Since I became a Fedora contributor in August 2015, I’ve spent a lot of time in the community. One of the great things about a big community like Fedora is that there are several different things to try out. I’ve always tried to do the most help in Fedora with my contributions. I prefer to make long-term, in-depth contributions than short-term, “quick fix”-style work. However, like many others, Fedora is a project I contribute to in my free time. Over the last month, I’ve come to a difficult realization.

KDE Events: Akademy 2017 and KDE Edu Sprint

  • Hey Mycroft, Drive Me to our Goals!
    Almost three months after Akademy 2017, I finally found the time to write a blog post about how I experienced it. Akademy is where I learn again about all the amazing things happening in our community, where I connect the dots and see the big picture of where all the effort in the various projects together can lead. And of course, I meet all the wonderful people, all the individual reasons why being in KDE is so amazing. This year was no different. Some people voiced their concern during the event that those who are not at Akademy and see only pictures of it on social media might get the feeling that it is mostly about hanging out on the beach and drinking beer, instead of actually being productive. Everyone who was ever at Akademy of course knows this impression couldn’t be further from the truth, but I’ll still take it as a reason to not talk about any of the things that were “just” fun, and focus instead on those that were both fun and productive.
