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

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’.

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.
