Open Hardware: X-FAB RISC-V Microcontroller

tuxmachines.org - Ned, 06/16/2019 - 09:50
  • X-FAB Silicon Foundries tapes-out open-source RISC-V MCU

    Together with crowd-sourcing IC platform partner Efabless Corporation, X-FAB Silicon Foundries has announced the first-silicon availability of the Efabless RISC-V System on Chip (SoC) reference design.

    This open-source semiconductor project went from design start to tape-out in less than three months using the Efabless design flow based on open-source tools. The mixed-signal SoC, called Raven, is based on the community developed ultra-low power PicoRV32 RISC-V core. Efabless has bench-tested the Raven at 100MHz, and based on simulations the design should be able to operate at up to 150MHz.

    The open-source top-level design uses X-FAB proprietary analog IP and is created with an open-source design flow. This hybrid open-source design brings the power of open innovation and at the same time protecting significant investment in proprietary IP.

100+ Benchmarks Between Clear Linux vs. Arch-Based Manjaro Linux - Summer 2019 Tests

tuxmachines.org - Ned, 06/16/2019 - 08:43

For those wondering how Intel's performance-optimized Clear Linux is comparing to the Arch-based Manjaro Linux distribution, here are a number of benchmarks on the same Intel Core i7 8700K in seeing how these rolling-release distros are competing for summer 2019.

More than 100 benchmarks were run on Clear Linux and Manjaro Linux using their latest releases for providing the very latest packages.

The same Intel Core i7 8700K system with 16GB of RAM and NVMe solid-state storage was used as a good example distribution for comparing these distros. Some Debian Buster tests on the i7-8700K are also coming in shortly for adding to the comparison.

Games: NetherWorld, Dota Underlords and DXVK

tuxmachines.org - Ned, 06/16/2019 - 02:13
  • NetherWorld, an impressive looking and weird narrative pixel-art action game is coming to Linux

    Currently in development by Hungry Pixel, NetherWorld has a pretty impressive pixel-art visual style that will mix insane action with narrative elements and it's coming to Linux.

    The actual plot of the game sounds pretty wild, starting with a marriage crisis as your wife decides to leave you and so you head to the local Bar to drown your sorrows. One thing leads to another with some unexpected turns, as you go on some sort of twisted journey as you explore the darkest corners of the land of NetherWorld.

    Discovered thanks to IndieDB, the developer recently confirmed to me that it will be supporting Linux.

  • Dota Underlords from Valve is already quite addictive and they're improving it quickly

    With Dota Underlords available for testing, I've now taken a look at it (thanks Scaine!) and so far I've been quite impressed.

    Valve have essentially rewritten the rules of "Valve Time", considering how quickly they've made it available and how promptly they've been responding to feedback. They've already adjusted it so you can switch between a Mobile and PC style for the user interface, fixed up the Linux version nicely (it runs beautifully!), removed the odd character outlines from the PC version and so on. Honestly, I'm genuinely surprised at how fast Valve are reacting with it.

    Since this is apparently the next big thing, it's nice to see that Linux gamers can jump on in right away thanks to Valve. As a reminder, the original creator of the mod is making a stand-alone version for the Epic Games Store and the League of Legends developer Riot are also doing their own.

  • DXVK 1.2.2 released with performance improvements and bug fixes

    DXVK, the incredible project that provides a Vulkan-based layer for D3D11 and D3D10 games run with Wine has another release now available. DXVK 1.2.2 is quite a small point release but as always, it still brings with it some nice changes.

    This time around Team Sonic Racing has a bug fix to help some startup issues and Planet Coaster should also see less startup issues, although Planet Coaster does need "additional wine patches" as of Wine 4.10.

    Also in this release are some CPU overhead optimizations, improved compute shader performance on Nvidia GPUs in some games with Nier: Automata being one that was noted and minor bugs were solved that caused wine test failures.

My personal journey from MIT to GPL

tuxmachines.org - Sob, 06/15/2019 - 17:07

As I got started writing open source software, I generally preferred the MIT license. I actually made fun of the “copyleft” GPL licenses, on the grounds that they are less free. I still hold this opinion today: the GPL license is less free than the MIT license - but today, I believe this in a good way.

[...]

I don’t plan on relicensing my historical projects, but my new projects have used the GPL family of licenses for a while now. I think you should seriously consider it as well.

Security Leftovers

tuxmachines.org - Sob, 06/15/2019 - 16:24
  • Yubico recalls government-grade security keys due security bug

    If you buy a government-grade security key, the one thing you really want from it is government-grade security. It's the very dictionary definition of "you had one job." That's why it's somewhat embarrassing that Yubico has put out a recall notice on its FIPS series of authentication keys which, it turns out, aren't completely secure.

  • [Microsoft's] EternalBlue exploit surfaces in bog standard mining attack Featured

  • Systemd Is Now Seeing Continuous Fuzzing By Fuzzit

    In hoping to catch more bugs quickly, systemd now has continuous fuzzing integration via the new "Fuzzit" platform that provides continuous fuzzing as a service. 

    New this week to systemd is the continuous fuzzing integration where every pull request / push will see some quick checks carried out while on a daily basis will be fuzzed in full for all targets.

  • DXVK 1.2.2 Brings Minor CPU Overhead Optimizations, Game Fixes

    In time for those planning to spend some time this weekend gaming, DXVK lead developer Philip Rebohle announced the release of DXVK 1.2.2 that will hopefully soon be integrated as part of a Proton update for Steam Play but right now can be built from source.

    While certain upstream Wine developers express DXVK being a "dead end" and are optimistic in favor of piping their WineD3D implementation over Vulkan, for Linux gamers today wanting to enjoy D3D11 Windows games on Linux the DXVK library continues working out splendid with great performance and running many Direct3D games with much better performance over the current WineD3D OpenGL code.

  • Intel 19.23.13131 OpenCL NEO Stack Adds Comet Lake Support

    We've seen the Intel Comet Lake support get pieced together in recent months in the different components making up the Intel Linux graphics stack while the compute-runtime is the latest addition. Comet Lake as a refresher is a planned successor to Coffeelake/Whiskeylake and expected to come out this year as yet more 9th Gen hardware. But Comet Lake should be interesting with rumored 10-core designs. Though with being more processors with Gen9 graphics, the Comet Lake Linux support basically boils down to adding in the new PCI IDs.

  • AMD Wires Its New Runtime Linker Into RadeonSI Gallium3D

    RadeonSI Gallium3D has already shifted over to using this new linker. Making use of the .rodata should help with efficiencies throughout the driver (more details in this forum thread) but at this point is mostly laying the groundwork for more improvements to be made moving forward.

  • Building IT Transformation Architecture with Red Hat OpenShift

    In the era of mobile applications, business challenges to the enterprise IT organizations are more dynamic than ever. Many enterprises have difficulties responding in time because of the inherent complexity and risk of integrating emerging technologies into existing IT architectures. In this article, I will share my experience on how to utilize Red Hat OpenShift as a “Middle Platform” (中台) for enterprises to construct its bimodal IT architecture with agile, scalable and open strategy.

    In the past year, I have discussed with many corporate customers–especially in the financial services industry–the challenges of digital transformation, and the solutions. Most of their difficulties are coming from “core systems” which have been working for more than 10 years.

  • Copr's Dist-Git

    In Copr, we use dist-git to store sources as well. However, our use case is different. In the past, Copr only allowed to build from URL. You provided a URL to your SRC.RPM and Copr downloaded it and built it. This was a problem when the user wanted to resubmit the build. The original URL very often did not exists anymore. Therefore we came with an idea to store the SRC.RPM somewhere. And obviously, the dist-git was the first idea.

  • File Synchronization App FreeFileSync Brings Another Update

    File synchronization software, FreeFileSync releases latest update with 10.13.

    FreeFileSync is a folder and file synchronization free software that is available for Linux, Windows and Mac. This software can sync between your devices files and folders and only sync the changed files/directories. That means it can identify the changed files and make sure to transfer those in backup systems.

    Armed with scheduling of transfers, JOB features for sync – this free and open source software is one of the best file sync/ backup software available today.

    FreeFileSync released 10.13 with bunch of big fixes and enhancements.

  • Utkarsh Gupta: GSoC Bi-Weekly Report - Week 1 and 2

    The idea is to package all the dependencies of Loomio and get Loomio easily installable on the Debian machines.

    The phase 1, that is, the first 4 weeks, were planned to package the Ruby and the Node dependencies. When I started off, I hit an obstacle. Little did we know about how to go about packaging complex applications like that.

    I have been helping out in packages like gitlab, diaspora, et al. And towards the end of the last week, we learned that loomio needs to be done like diaspora.

  • Annual Report 2018: LibreOffice Conference

    The LibreOffice Conference is the annual gathering of the community, our end-users, and everyone interested in free office software. Every year, it takes place in a different country and is supported by members of the LibreOffice commercial ecosystem. In 2018, the conference was organized by the young and dynamic Albanian community at Oficina in Tirana, from Wednesday, September 26, to Friday, September 28, the eight anniversary of the LibreOffice project. Here’s a quick video recap – read on for more details…

  • New Lightworks Beta Version 14.6 revision 114986 Now Available on Windows Linux and Mac!

    It is strongly recommended that users backup their project folder before installing any new Beta build of Lightworks.

    We are pleased to announce the second Beta of Lightworks 14.6 which includes many changes based on Forum feedback. Excellent work all round and we are hopeful that this Beta Cycle will be short lived. We hope you enjoy all the features and changes in the latest version which can be found in the : Changelog pages

  • Lightworks 14.6 Remains A Closed-Up Blob, But At Least The Linux Support Continues

    It was nearly a decade ago the high-end, commercial video software editing solution Lightworks announced they would be going open-source but to this day that milestone has yet to be materialized. Lightworks though does continue advancing with their v14.6 release on the horizon and at least their added Linux support continues to be expanded upon.

    EditShare, the company behind Lightworks, really dropped the ball when it came to their open-source plans. All that we've been able to gather over these years is that they hit some complexities with their original open-source plans and aren't committed enough in seeking to work through those issues to make the code public. So at the end of the day Lightworks is still a closed-source non-linear video editor, but at least it's one of the most feature-rich/professional-grade solutions with native Linux support.

KDE: Site Description Update, Boost and Meeting KDE in València

tuxmachines.org - Sob, 06/15/2019 - 16:15
  • Jonathan Riddell: KDE.org Description Update

    The KDE Applications website was a minimal possible change to move it from an unmaintained and incomplete site to a self-maintaining and complete site. It’s been fun to see it get picked up in places like Ubuntu Weekly News, Late Night Linux and chatting to people in real life they have seen it get an update. So clearly it’s important to keep our websites maintained. Alas the social and technical barriers are too high in KDE. My current hope is that the Promo team will take over the kde-www stuff giving it communication channels and transparancy that doesn’t currently exist. There is plenty more work to be done on kde.org/applications website to make it useful, do give me a ping if you want to help out.

  • Done with boost

    One of the so called pillar of the c++ world, boost, sucks a lot when it comes to documentation, I wouldn’t have to write more than one blog post if they had their documentation in place. It has been almost a month that I have started working on the Magnetic Lasso and I wasted most of the time fighting with boost instead of working on my algorithm. Okay, fine I am getting paid for it, I shouldn’t complain.

Linux Devices: Librem, NGD and Commell SBCs

tuxmachines.org - Sob, 06/15/2019 - 16:11
  • Todd Weaver on Digital Trends Live

    I have just had a wonderful conversation with Greg Nibler, from Digital Trends Live, about all kinds of different ways these issues are being tackled. Greg started by asking me to introduce Purism, and why we do what we do.

    Well, we started around 2014 as a Social Purpose Company: we advance social good over maximizing profit. We build laptops, a secure token called a Librem Key, and we are also coming out with the Librem 5: a smartphone that doesn’t run on Android nor IOS, but our own operating system PureOS (the same you get on our laptops). These are available today, with the Librem 5 phone (on pre-order now) coming out in Q3 of this year. Our services—chat, email, social media, VPN—are all standardized protocols, decentralized, with no data retention and end-to-end encrypted. We are going to continue to put out more and more hardware, software, and services as we progress.

    I’m kind of a hardcore geek, both in the hardware and software side—but I also am a digital rights activist, making Purism my dream come true by combining hardware, software and services together, in one convenient package. What is awesome is that our entire team is excited about the exact same thing: making convenient products that respect people. Hardware is a little bit more security-minded and privacy-focused, it is where the hardcore audience is: it really gets down to a trust and verified model. The same happens with software: it all needs to be released.

  • What's up with computational storage

    The advantage of this approach is that the processor can run a standard operating system (Ubuntu Linux), and allows any software that runs on Ubuntu to be used for in situ computing in NGD’s drives. The drive itself can also be used as a standard SSD.

  • Up to 4.3GHz, hexa-core Coffee Lake-H on tap in new 3.5-inch SBC

    Like the earlier Commell SBCs, the LE-37M is accompanied by Windows drivers, but Linux support is mentioned in the manual. The LE-37M is designed for imaging, machine vision, infotainment, medical, and gaming machine applications.
