5 cool terminal pagers in Fedora

Large files like logs or source code can run into the thousands of lines. That makes navigating them difficult, particularly from the terminal. Additionally, most terminal emulators have a scrollback buffer of only a few hundred lines. That can make it impossible to browse large files in the terminal using utilities which print to standard output like cat, head and tail. In the early days of computing, programmers solved these problems by developing utilities for displaying text in the form of virtual “pages” — utilities imaginatively described as pagers.

Pagers offer a number of features which make text file navigation much simpler, including scrolling, search functions, and the ability to feature as part of a pipeline of commands. In contrast to most text editors, some terminal pagers do not require loading the entire file for viewing, which makes them faster, especially for very large files.

Raspberry Pi 4 V3D Driver Reaches OpenGL ES 3.1 Conformance

  • Raspberry Pi 4 V3D Driver Reaches OpenGL ES 3.1 Conformance

    The V3D Gallium3D driver that most notably offers the open-source graphics support for the Raspberry Pi 4 is now an official OpenGL ES 3.1 implementation. Consulting firm Igalia has continued working on the V3D driver since Eric Anholt left Broadcom. Igalia had ironed out OpenGL ES 3.1 support and last month also went on to begin tackling geometry shaders and more.

  • Iago Toral: I am working on the Raspberry Pi 4 Mesa V3D driver

    Yeah… this blog post is well overdue, but better late than never! So yes, I am currently working on progressing the Raspberry Pi 4 Mesa driver stack, together with my Igalian colleagues Piñeiro and Chema, continuing the fantastic work started by Eric Anholt on the Mesa V3D driver. The Raspberry Pi 4 sports a Video Core VI GPU that is capable of OpenGL ES 3.2, so it is a big update from the Raspberry Pi 3, which could only do OpenGL ES 2.0. Another big change with the Raspberry Pi 4 is that the Mesa v3d driver is the driver used by default with Raspbian. Because both GPUs are quite different, Eric had to write an all new driver for the Raspberry Pi 4, and that is why there are two drivers in Mesa: the VC4 driver is for the Raspberry Pi 3, while the V3D driver targets the Raspberry Pi 4.

  • Raspberry Pi 4 V3D driver gets Geometry Shaders

    I actually landed this in Mesa back in December but never got to announce it anywhere. The implementation passes all the tests available in the Khronos Conformance Tests Suite (CTS). If you give this a try and find any bugs, please report them here with the V3D tag.

  • Raspberry Pi 4 V3D driver gets OpenGL ES 3.1 conformance

    So continuing with the news, here is a fairly recent one: as the tile states, I am happy to announce that the Raspberry Pi 4 is now an OpenGL ES 3.1 conformant product!. This means that the Mesa V3D driver has successfully passed a whole lot of tests designed to validate the OpenGL ES 3.1 feature set, which should be a good sign of driver quality and correctness. It should be noted that the Raspberry Pi 4 shipped with a V3D driver exposing OpenGL ES 3.0, so this also means that on top of all the bugfixes that we implemented for conformance, the driver has also gained new functionality! Particularly, we merged Eric’s previous work to enable Compute Shaders.

Software tips for nerds

I use Vim for almost a decade now, which is probably the longest I’ve sticked to some application. During that time, I repeatedly tried to use it as an IDE but inevitably failed each time. Let’s remember eclim as my Java IDE. I work almost exclusively on projects written in Python, which can be beautifully done in Vim but because of a gap in my skills, I was reliant on PyCharm. Thankfully, not anymore. My biggest issue was misusing tabs instead of buffers and poor navigation within projects. Reality check, do you open one file per tab? This is a common practice in other text editors, but please know that this is not the purpose of tabs in Vim and you should be using buffers instead. Please, give them a chance and read Buffers, buffers, buffers. Regarding project navigation, have you ever tried shift shift search in PyCharm or other JetBrains IDE? It’s exactly that thing, that you wouldn’t even imagine but after using it for the first time, you don’t understand how you lived without. What it does is, that it interactively fuzzy-finds files and tags (classes, functions, etc) that matches your input, so you can easily open them. In my opinion, this unquestionably defeats any other way of project navigation like using a file manager, NerdTree, or find in the command line. Fortunately, both of these problems can be solved by fzf.vim, which quickly became one of my most favorite Vim plugins. Please read this section about fzf plugin. I am forever grateful to Ian Langworth for writing VIM AFTER 11 YEARS, EVERYTHING I MISSED IN “VIM AFTER 11 YEARS” and VIM AFTER 15 YEARS articles. If you are a Vim user, those are an absolute must-read. Read more
