Python Series Part 19: Binding Keys and Events - Part 1

In the article on Tkinter Buttons, I mentioned binding keys to allow a key press to activate a button. Of course, other widgets have this ability as well. For buttons, we use an ‘underline’ feature to underline a character to show a user can access it with a key press instead of clicking it with the mouse. We can use the key binding process more later when we get to the article on ‘menus’. We will also cover a lengthy list of Events that can occur, because binding keys is creating an... https://www.linux.org/threads/python-series-part-19-binding-keys-and-events-part-1.57438/

Open-Source Nouveau+NVK vs. NVIDIA 580 Linux Gaming/Graphics & Compute Driver Performance

This Black Friday is an in-depth look at the current performance of the open-source NVIDIA Linux driver stack with the Nouveau kernel driver (the Nova driver not yet being ready for end-users) paired with the latest Mesa NVK driver for open-source Vulkan API support. With that NVK Vulkan driver is also looking at the OpenGL performance using the Zink OpenGL-on-Vulkan driver used now for OpenGL on modern NVIDIA GPUs rather than maintaining the Nouveau Gallium3D driver. Plus the Rusticl driver for OpenCL compute atop the NVK driver. This fully open-source and latest NVIDIA Linux driver support was compared to NVIDIA's official 580 series Linux driver. Both RTX 40 Ada and RTX 50 Blackwell graphics cards were tested for this thorough GPU driver comparison.

AMD ISP4 Linux Webcam Driver Updated For HP ZBook Ultra G1a & Future Ryzen Laptops

We eagerly await to see if the AMD ISP4 driver will be ready for mainlining in the imminent Linux v6.19 merge window but it's getting down to the wire and thus looking less likely it will make it unless action is taken in the coming days. Today though a sixth version of this AMD ISP4 image signal processor driver was posted for this last piece of the puzzle in enabling the web camera on the HP ZBook Ultra G1a Strix Halo laptop as well as future Ryzen high-end laptops...

Vulkan 1.4.335 Released With The Very Notable VK_EXT_present_timing

Vulkan 1.4.335 released a few hours ago as the latest iteration of this high performance graphics and compute API. With being just a week since the prior update and given the US Thanksgiving week, it's on the lighter side in terms of issues addressed. There is one new extension though and it's a big one: VK_EXT_present_timing is finally merged...

Ubuntu 26.04 Snapshot 1 Download

Ubuntu 26.04 Snapshot 1 is now available to download, the first of 5 monthly development release planned between now and April 2026. Canonical began publishing monthly Ubuntu snapshots during the Ubuntu 25.10 development cycle as a way to test and fine-tune a new automated build and testing infrastructure. They’re produced for all flavours too, not just the main edition. As their name implies, Ubuntu Snapshots are simply a snapshot of development on the date they were made. Canonical’s engineers refer to them as “throwaway artefacts” so don’t assume they’re vetted alpha builds. Though not a targeted ‘milestone’ in the way […]
