Programming: ThreadStack and Qt for WebAssembly

  • ThreadStack: Yet Another C++ Project Trying To Make Multi-Threading Easier
    ThreadStack is yet another C++ project trying to make it easier dealing with multiple CPU threads. This latest open-source C++ threading project comes out of academia research. ThreadStack is self-described by its developer, Erkam Murat Bozkurt, as "an innovative software which produces a class library for C++ multi-thread programming and the outcome of the ThreadStack acts as an autonomous management system for the thread synchronization tasks. ThreadStack has a nice and useful graphical user interface and includes a short tutorial and code examples. ThreadStack offers a new way for multi-thread computing and it uses a meta program in order to produce an application specific thread synchronization library." Erkam has been working the rounds trying to raise awareness for this research on the GCC and LLVM mailing lists.
  • Beta for Qt for WebAssembly Technology Preview
    WebAssembly is a bytecode format intended to be executed in a web browser. This allows an application to be deployed to a device with a compliant web browser without going through any explicit installation steps. The application will be running inside a secure sandbox in the web browser, making it appropriate for applications that do not need full access to the device capabilities, but benefits from a swift and uncomplicated installation process.
  • Qt for WebAssembly Tech Preview Reaches Beta
    As part of next month's Qt 5.11 tool-kit update, a new technology preview module will be WebAssembly support for running Qt5 user-interfaces within your web-browser.

Kernel and Graphics: BUS1, Linux 4.17 RC2, Wayland's Weston and Mesa

  • BUS1 Still Remains Out Of The Mainline Linux Kernel, But DBus-Broker Continues
    The BUS1 in-kernel IPC mechanism born out of the ashes of KDBUS still hasn't been mainlined in the Linux kernel, but its code is still improved upon from time to time. At least though DBus-Broker as a new performance-oriented D-Bus implementation continues gaining ground in user-space. DBus-Broker was announced last year as a new message bus implementation of D-Bus focused on high performance and reliability while continuing to offer compatibility with the original D-Bus implementation.
  • Linux 4.17-rc2 Kernel Released With Mostly Routine Changes
    Linus Torvalds has announced the availability of the second weekly test release for what is becoming the Linux 4.17 kernel.
  • Wayland's Weston Gets Optimizations For Its Pixman Renderer
    Wayland's Weston reference compositor with its Pixman software-based renderer back-end has received a number of performance optimizations. Fabien Lahoudere of Collabora posted a set of patches today to optimize the Pixman renderer for Weston. In particular, there are optimizations around compositing damage to the screen as well as optimizing the shadow buffer usage. The Weston Pixman renderer is often used as a software accelerated fallback in cases where no GPU hardware acceleration may be available. As implied by the name, it uses the long-standing Pixman library that is also used by Cairo, the X.Org Server, etc, for pixel manipulation on the CPU.
  • Panfrost Gallium3D Driver For ARM Mali Can Now Render A Cube
