Flush 0.9.12 Review – A Lightweight BitTorrent Client

Filed under
Reviews

BitTorrent clients feel right at home on Linux, and this means that there are a ton of them, all doing mostly the same thing, with some differences in features and the interface. Interestingly enough, some of the clients on the Linux platform try really hard to copy the way uTorrent looks and works on Windows, which is rather strange for a software.

Android signage player supports Apple iBeacon

Filed under
Android

Noxel’s Android-based Xtream A700 signage player integrates Apple’s BLE-based iBeacon indoor positioning tech with Noxel’s cloud-based signage service.

Noxel claims its Xtream A700 is the most powerful Android signage computer around, and considering its quad-core system-on-chip and the relative novelty of Android signage, we imagine they are correct. Aside from the sheer performance, the device is notable for its use of Apple’s iBeacon indoor positioning technology, which can provide precise location information via Bluetooth Low Energy (BLE). The device’s iBeacon support enables retailers and brand marketers to provide in-store navigation and location-specific push messaging to smartphones, says the company.

Google's Nexus phones will reportedly be replaced by premium Android Silver handsets

Filed under
Android

The Android Silver project, which was rumored earlier this month, has today been corroborated by four fresh sources, all of whom point to a major shift in Google's mobile strategy. The Information reports that the current scheme of offering Nexus-branded handsets with Google's unadulterated vision of the best Android user experience will be scrapped, to be replaced by a set of high-end Silver phones that will closely adhere to it. The change is both expansive and expensive, as Google is said to be planning to spend heavily on promoting these devices in wireless carriers' stores and through advertising, essentially subsidizing the development and marketing costs for its hardware partners.

The Chromebook doesn't require big hardware, so the component inventory is not too heavy.

Graphics: VC4 and AMDVLK Driver

  • VC4 display, VC5 kernel submitted
    For VC5, I renamed the kernel driver to “v3d” and submitted it to the kernel. Daniel Vetter came back right away with a bunch of useful feedback, and next week I’m resolving that feedback and continuing to work on the GMP support. On the vc4 front, I did the investigation of the HDL to determine that the OLED matrix applies before the gamma tables, so we can expose it in the DRM for Android’s color correction. Stefan was also interested in reworking his fencing patches to use syncobjs, so hopefully we can merge those and get DRM HWC support in mainline soon. I also pushed Gustavo’s patch for using the new core DRM infrastructure for async cursor updates. This doesn’t simplify our code much yet, but Boris has a series he’s working on that gets rid of a lot of custom vc4 display code by switching more code over to the new async support.
  • V3D DRM Driver Revised As It Works To Get Into The Mainline Kernel
    Eric Anholt of Broadcom has sent out his revised patches for the "V3D" DRM driver, which up until last week was known as the VC5 DRM driver. As explained last week, the VC5 driver components are being renamed to V3D since it ends up supporting more than just VC5 with Broadcom VC6 hardware already being supported too. Eric is making preparations to get this VideoCore driver into the mainline Linux kernel and he will then also rename the VC5 Gallium3D driver to V3D Gallium3D.
  • AMDVLK Driver Gets Fixed For Rise of the Tomb Raider Using Application Profiles
    With last week's release of Rise of the Tomb Raider on Linux ported by Feral Interactive, when it came to Radeon GPU support for this Vulkan-only Linux game port the Mesa RADV driver was supported while the official AMDVLK driver would lead to GPU hangs. That's now been fixed. With the latest AMDVLK/XGL source code as of today, the GPU hang issue for Rise of the Tomb Raider should now be resolved.

AMD Ryzen 7 2700X Linux Performance Boosted By Updated BIOS/AGESA

With last week's initial launch-day Linux benchmarks of the Ryzen 5 2600X / Ryzen 7 2700X some found the Linux performance to be lower than Windows. While the root cause is undetermined, a BIOS/AGESA update does appear to help the Linux performance significantly at least with the motherboard where I've been doing most of my tests with the Ryzen 7 2700X. Here are the latest benchmark numbers. Read more

GNU: The GNU C Library 2.28 and Guix on Android

  • Glibc 2.28 Upstream Will Build/Run Cleanly On GNU Hurd
    While Linux distributions are still migrating to Glibc 2.27, in the two months since the release changes have continued building up for what will eventually become the GNU C Library 2.28. The Glibc 2.28 work queued thus far isn't nearly as exciting as all the performance optimizations and more introduced with Glibc 2.27, but it's a start. Most notable at this point for Glibc 2.28 is that it will now build and run cleanly on GNU/Hurd without requiring any out-of-tree patches. There has been a ton of Hurd-related commits to Glibc over the past month.
  • Guix on Android!
    Last year I thought to myself: since my phone is just a computer running an operating system called Android (or Replicant!), and that Android is based on a Linux kernel, it's just another foreign distribution I could install GNU Guix on, right? It turned out it was absolutely the case. Today I was reminded on IRC of my attempt last year at installing GNU Guix on my phone. Hence this blog post. I'll try to give you all the knowledge and commands required to install it on your own Android device.
  • GNU Guix Wrangled To Run On Android
    The GNU Guix transactional package manager can be made to run on Android smartphones/tablets, but not without lots of hoops to jump through first.
