Graphics: Mesa, Xwayland, and LuxCoreRender

  • Mesa 21 Broke VAAPI Hardware Encoding On Machines With AMD Graphics Cards. A Fix Is Coming. - LinuxReviews

    Those of you who have tried to hardware encode video using AMD hardware after upgrading to Mesa 21 may have noticed that the encoded video is, in fact, not a video - it's some kind of odd slide-show with one new frame every 5 seconds or so. Mesa 20.3 didn't have that problem, Mesa 21 and the newly released 21.0.2 bug-fix do. The Mesa developers are aware of the problem we are referring to and a patch has been merged into the upcoming 21.0.3 version scheduled to be released around two weeks from now.

  • Xwayland Has Gained Support For Hardware Acceleration On Machines With Nvidia graphics Cards - LinuxReviews

    Xwayland, a component that allows X programs to run on the Wayland display server, has finally gained support for running X programs under Wayland with hardware acceleration on Nvidia hardware. This has been a sour-spot for Wayland since its inception, not having backwards compatibility with the most widely used display server is kind of a bummer. Support is finally there in the git master branch thanks to what looks to be a joint Nvidia/RedHat effort.

  • LuxCoreRender 2.5 Open-Source PBR Renderer Released With NVIDIA OptiX/RTX Support - Phoronix

    The LuxCoreRender open-source physically based rendering (PBR) software is out with its latest major feature release that now offers NVIDIA OptiX/RTX acceleration support alongside the existing CPU, NVIDIA CUDA, and OpenCL rendering paths. LuxCoreRender 2.5 now allows making use of NVIDIA OptiX/RTX acceleration when running with a supported graphics card on the NVIDIA proprietary driver stack.

Fedora Linux Download ISO 64-bit

We can download Fedora Linux free of cost to install on PC, Laptop, or virtual machines. It is developed and maintained by the Fedora project community while sponsored by Red Hat. It came into existence when in 2003 Red Hat decided to turn its end-user Linux distribution into a community project, and so the Fedora distribution was born. Fedora uses and publishes software that are available under a free license. The project is led by the Fedora Project Board, which includes members of the community as well as Red Hat employees. The key goal of developing Fedora is to provide a new, versatile, and free ( open source ) operating system. And being an upstream source code of the commercial Red Hat Enterprise Linux distribution, it helps a lot in developing and providing stability to RHEL. Therefore, in short, it is a testing platform for many new technologies, and technologies that are considered available will eventually be added to Red Hat Enterprise Linux. Read more

Python Leftovers

  • Create a JSON Response in Python

    JSON (JavaScript Object Notation) file is a very popular medium to interchange data between different formats. It contains data in text format that is supported by various languages such as Python, PHP, PERL, etc. The main purpose of the JSON file is to transfer data between the server and the client. The requests are generated by Python to retrieve the data from a particular resource URI. If the response of the request is returned in JSON format then the content of the response can be retrieved using the response.json() function. It returns the response by using a Python dictionary object. How this function can be used to parse JSON response using the Python request library will be shown in this tutorial.

  • Use of Django Request and Response Objects – Linux Hint

    The Request-response cycle is used to transfer the data between the client and server in all types of web APIs. The client-server architecture is used in the Django framework to implement the web application. The request and response are the two main components of the client-server application. An HttpRequest object is created in the Django application when a client requests any resource. A particular view function is used to handle the request and send the response using the HttpResponse object. The uses of different attributes and methods of HttpRequest and HttpResponse classes of the Django framework will be explained in this tutorial.

  • Form Validation in Django – Linux Hint

    Form validation is a very important task for any web application to enter valid data in the database. The users of the application will not be able to insert invalid data if the form data are validated before submitting. Django is called MVT (Model View Template) based framework where the task of the controller is done by this framework itself. The database-related tasks are done by Model and the data are presented to the template using View. The fields of a form are generated based on the particular model that will insert data into the Django database after validation. One type of validation is done by the browser-based on the field type that is defined in the model. Using the is_valid() function is another way to check the form data whether they are valid or not after submitting the form. This tutorial will show you how the data can be inserted into the Django database after validating the form.

  • How to Build a Basic Search for a Django Site? – Linux Hint

    A particular content of any site is normally retrieved by the users through Google search. However, if this search option is implemented on the website, then the users can easily find their desired content within the site without using Google search. . Another benefit of adding a search option within a website is that the developer can manage the searching output properly. That means he can control which content of the site will appear or not. This tutorial will show the process of implementing the basic search in the Django site.
