GNS3 is a graphical network simulator which lets you to create a virtual network. You don't need any hardware like routers, switches, or even endpoints (workstation computers).

This open source tool can be useful for setting up a local network in an office or other environments, and also for troubleshooting purposes.

  • AMD Publishes Vega 7nm ISA Documentation - 300 More Pages Of GPU Docs

    Beyond AMD's open-source graphics driver stack of the past decade, part of their original open-source plans have also involved providing public (NDA-free) GPU hardware documentation. That has come with time though the documentation drops are not coordinated in-step with code drops. Out today, for example, is the ISA documentation on Vega 7nm. Back in 2017 was the timely release of the Vega ISA documentation and earlier this summer was even the RDNA 1.0 ISA documentation but missing out until now was the Vega 7nm ISA documentation.

  • Intel's Iris Gallium3D Driver Continuing To See Performance Optimizations On Mesa 20.0

    With the current Mesa 19.3 there is the Intel Gallium3D driver generally performing much better than their "classic" i965 driver and for Mesa 20.0 it looks to only make more ground as it switches over to this driver by default. Beyond the recent build system changes for supporting an Intel Gallium3D default and building it as part of the default x86/x86_64 Gallium3D drivers with hopes of soon flipping the switch for Broadwell and newer, more performance optimizations are still being done.

  • Dreamcast emulator Flycast adds a Vulkan renderer

    There seems to be quite a lot of interest in Vulkan lately, as more projects begin using it. Now we have the Dreamcast emulator Flycast adding Vulkan support. In the technical blog post announcing it on the Libretro site, it gives a bit of brief history of the Dreamcast GPU and mentions the usual "less overhead, more reliability and better performance in many cases" when it comes to using Vulkan although it's a lot more complicated to use.

  • NVIDIA have two new Linux drivers available, one stable and one Vulkan Beta

    NVIDIA continue pushing their drivers forwards with two new Linux driver updates available. Let's take a quick look. First, the stable 440.44 driver release as part of their long-lived branch. This adds support for the Quadro T2000 with Max-Q Design, you can now use the "__GL_SYNC_DISPLAY_DEVICE" environment variable for Vulkan applications and it fixes a few bugs like tearing with a G-SYNC or G-SYNC Compatible monitor when you've got something running directly on a display (like VR).

Watch these videos from the Linux App Summit

For some, the holidays are a hectic time of shopping, cooking, and a house overflowing with loved ones. For others, they’re quiet times spent with just a few friends, or even in solitude behind the warm glow of a computer monitor. And for still others, it’s a workday like any other. No matter how you end up spending the holiday season this year, there’s comfort to be found in the Linux App Summit of 2019. This summit, which combined the strengths of everyone involved in developing applications for Linux, focused on a few major topics... Read more

Qt Creator 4.11 is released

We added experimental support for Qt for WebAssembly and Qt for MCUs. We improved the general handling of configuring, building and running projects in so many smaller ways that I fail to choose anything for being highlighted here. If you use CMake 3.14 or later we now use CMake's file-base API for configuring and parsing projects. Which behaves much more reliably than the previous server-mode, especially if you also use CMake from a terminal or other applications. Read more
