Docker has a business plan headache

1 hour 43 min ago
Docker is the container technology of choice, but that doesn[he]#039[/he]t translate into Docker the successful business. Whatever Docker the business' future, Docker the technology is both open source and a standard. Docker could close up shop today, and you'd still be using Docker containers tomorrow.

4 cool new projects to try in COPR for February

Friday 23rd of February 2018 12:24:47 PM
COPR is a collection of personal repositories for software that isn’t carried in Fedora. Some software doesn’t conform to standards that allow easy packaging. Or it may not meet other Fedora standards, despite being free and open source. COPR can offer these projects outside the Fedora set of packages. Software in COPR isn’t supported by Fedora infrastructure or signed by the project. However, it can be a neat way to try new or experimental software.

Aquaris E4.5 Ubuntu Phone - With Android

I ever so slightly regret the "upgrade" to Android. With a version less than the tablet, the UI changes are extremely noticeable, and the transition isn't as smooth. The device lags, and it just doesn't have enough processing power to give the necessary feel of goodness and elegance. On the other hand, you get tons of native applications that you can actually use, as opposed to the Ubuntu Touch idea. Shame really. For 'tis a compromise. If you ask me, I wholeheartedly embrace the M10 tablet upgrade, but on the phone, you might as well keep Ubuntu unless you need the device for serious use. If it's just an opportunistic call/SMS thing for when abroad and such, or to loan to friends, the original combo is adequate. If you need apps, then Android is the way to go, but do not except any miracles. It won't be speedy, and it won't be too pretty. All in all, an okay player. It is silly attaching sentiments to software or hardware, but I do guess I will fondly remember the Ubuntu phone attempt as a noble idea to make something great and fun. I could have kept the device in its original state, perhaps, but in the end, it would have ended in a pile of ancient stuff you keep around for a decade until you decide you need to throw it away to leave room for fresh memories and less ancient stuff. Having a flawless Android experience would have helped soften the edge, but as it is, it remains the bittersweet attempt at what could have been a revolution. The end.

FATHOM releases Crystallon

  • FATHOM releases Crystallon, an open-source software for lattice-based design
    Lattice structures are integral to 3D printed designs, and Aaron Porterfield, an industrial designer at additive manufacturing service bureau FATHOM, has developed Crystallon, an open source project for shaping them into structures.
  • FATHOM Introduces Open Source Software Project for Generating 3D Lattice Structures
    California-based FATHOM, which expanded its on-site managed services and announced important partnerships with Stratasys and Desktop Metal last year, is introducing a fascinating new open source project called Crystallon, which uses Rhino and Grasshopper3D to create lattice structures. FATHOM industrial designer Aaron Porterfield, also an Instructables member, developed the project as an alternative to designing lattices with commercially available software. He joined the company’s design and engineering team three years ago, and is often a featured speaker for its Design for Additive Manufacturing (DfAM) Training Program – and as the project developer, who better to explain the Crystallon project?

Kernel and Graphics: Machine Learning, Mesa, Wayland/Mir, AMDGPU

  • AI-Powered / Machine Learning Linux Performance Tuning Is Now A Thing
    A year and a half ago I wrote about a start-up working on dynamically-tuned, self-optimizing Linux servers. That company is now known as Concertio and they just launched their "AI powered" toolkit for IT administrators and performance engineers to optimize their server performance. Concertio Optimizer Studio is their product making use of machine learning that aims to optimize Linux systems with Intel CPUs for peak performance by scoping out the impact of hundreds of different tunables for trying to deliver an optimal configuration package for that workload on that hardware.
  • Pengutronix Gets Open-Source 3D Working On MX8M/GC7000 Hardware
    We've known that Pengutronix developers had been working on i.MX8M / GC7000 graphics support within their Etnaviv open-source driver stack from initial patches posted in January. Those patches back at the start of the year were for the DRM kernel driver, but it turns out they have already got basic 3D acceleration working.
  • SDL Now Disables Mir By Default In Favor Of Wayland Compatibility
    With Mir focusing on Wayland compatibility now, toolkits and other software making direct use of Mir's APIs can begin making use of any existing Wayland back-end instead. GTK4 drops the Mir back-end since the same can be achieved with the Wayland compatibility and now SDL is now making a similar move.
  • Mesa 18.1 Receives OpenGL 3.1 With ARB_compatibility For Gallium3D Drivers
    Going back to last October, Marek of AMD's open-source driver team has been working on ARB_compatibility support for Mesa with a focus on RadeonSI/Gallium3D. Today that work was finally merged. The ARB_compatibility support allows use of deprecated/removed features of OpenGL by newer versions of the specification. ARB_compatibility is particularly useful for OpenGL workstation users where there are many applications notorious for relying upon compatibility contexts / deprecated GL functionality. But ARB_compatibility is also used by a handful of Linux games too.
  • AMDGPU In Linux 4.17 Exposes WattMan Features, GPU Voltage/Power Via Hwmon
    AMD's Alex Deucher today sent in the first pull request to DRM-Next of AMDGPU (and Radeon) DRM driver feature material that will in turn be merged with the Linux 4.17 kernel down the road. There's some fun features for AMDGPU users coming with this next kernel! First up, Linux is finally getting some WattMan-like functionality after it's been available via the Windows Radeon Software driver since 2016. WattMan allows for more fine-tuning of GPU clocks, voltages, and more for trying to maximize the power efficiency. See the aforelinked article for details but currently without any GUI panel for tweaking all of the driver tunables, this WattMan-like support needs to be toggled from the command-line.
