-Werror pain persists as Linus Torvalds issues Linux 5.15rc2

Monday 20th of September 2021 06:32:09 AM
Linus Torvalds has revealed that winding back the decision to default to -Werror – and therefore make all warnings into errors – has made for another messy week of work on the Linux kernel. "So I've spent a fair amount of this week trying to sort out all the odd warnings, and I want to particularly thank Guenter Roeck for his work on tracking where the build failures due to -Werror come from," Torvalds wrote in his weekly missive about the state of kernel development.

Why my public library chooses Linux and open source

Sunday 19th of September 2021 01:42:16 AM
The Crawford County Federated Library System has been using Linux and open source software in its IT operations since 1999. They realized early on the potential of open source and integrated it into their enterprise. They were a part of my own Linux journey as I built a content filtering system for our school district. Twenty years ago, there were few models for the use of open source in libraries and education. Meadville Public Library and the Crawford County Federated Library System were the leaders then and now.

Try this Linux web browser dedicated solely to web applications

When I'm on the go, I need everything to work as efficiently as possible. And although you might be thinking, "But a web browser is as efficient as it gets, right?" That depends on what task you're doing and what site you're working with. This is especially so in the modern age of web applications and with constantly on-the-move staff. Instead of always having a full-blown, kitchen-sink-type web browser, sometimes we need something a bit more stripped-down, a tool that is geared toward one thing and one thing only—web applications.

Graphics: GL, Libinput, NVIDIA, and AMD

  • Mike Blumenkrantz: Underwater

    I got a request recently to fix up the WebGL Aquarium demo. I’ve had this bookmarked for a while since it’s one of the only test cases for GL_EXT_multisampled_render_to_texture I’m aware of, at least when running Chrome in EGL mode. Naturally, I decided to do both at once since this would be yet another extension that no native desktop driver in Mesa currently supports.

  • xf86-input-libinput 1.2.0

    This release introduces support for touchpad gestures that will be available as part of X server 21.1. Additionally high-resolution scrolling data is now acquired from libinput if available and sent downstream to X server. The default scroll distance has been bumped to 120 in the process, but this should not affect correctly written clients.

  • xf86-input-libinput 1.2 Brings Touchpad Gestures, High Resolution Scrolling - Phoronix

    For those continuing to make use of the X.Org Server, xf86-input-libinput 1.2 is now available for integrating the latest functionality of libinput input handling library. Libinput 1.19 released last week with support for hold gesture types and high resolution wheel scrolling. The xf86-input-libinput 1.2 release for this X.Org DDX now supports touchpad gestures and high resolution scrolling data as well when pairing this driver with libinput 1.19. In the case of the hold gestures, it requires to be used in conjunction with the forthcoming X.Org Server 21.1 release.

  • NVIDIA Prepares The Linux Kernel For Future Laptops With EC-Driven Backlights - Phoronix

    NVIDIA is contributing a new open-source driver to the upstream Linux kernel for dealing with upcoming laptops where the backlight controls are handled by the device's embedded controller (EC). With Linux 5.16 later this year NVIDIA is ready with the "wmaa-backlight-wmi" driver for EC-based backlight controls for upcoming laptop/notebook computers.

  • AMD Continues CRIU Work To Checkpoint/Restore ROCm Compute Workloads - Phoronix

    Earlier this year AMD went public with prototyping CRIU support for Radeon GPUs around ROCm to be able to checkpoint/freeze running compute workloads and to then restore them at a later point. This CRIU focus is driven by their big accelerator needs and forthcoming supercomputers for migrating workloads particularly within containers. AMD continues working on CRIU support for GPUs and last week provided an update on the project.

  • How to scale GRUB menu on 4K displays

    Several weeks ago, I installed Kubuntu 20.04 on my IdeaPad Y50-70, a somewhat old but rather capable 15.6-inch laptop with a 4K screen resolution. Predictably, the device wasn't usable in its native screen mode, and I had to make everything bigger, scaling and all that. In the end, I managed to create an ergonomically comfortable setup, with two exceptions - the login menu, and the boot menu. The former gave me some grief, but I was able to get it sorted. With GRUB, there were more problems. One, the menu wouldn't show, even though I had a dual-boot configuration in place. Two, the menu was tiny, with the text barely readable. So I embarked on a journey of GRUB modifications, hence this tutorial. Let me show you how you can make the GRUB menu bigger on HD/UHD displays.

  • Use this Linux command-line tool to learn more about your NVMe drives | Opensource.com

    NVMe stands for Non-Volatile Memory Express, and it refers to how software and storage communicate across PCIe and other protocols, including TCP. It's an open specification led by a non-profit organization and defines several forms of solid-state storage. My laptop has an NVMe drive, as does my desktop. And they're fast. I love how quickly my computers boot and how quickly they're able to read and write data. There's no perceptible delay. It also didn't take long for me to get curious about the technology driving this ultra-fast storage, so I did a little investigation. I learned that NVMe drives consume less power while delivering much faster access to data compared to even SSD drives over SATA. That was interesting, but I wanted to know more about my particular NVMe drives, and I wanted to know how they compared with other drives. Could I securely erase the drive? How could I check its integrity? Those questions led me to an Internet search that yielded an open source project with a collection of tools to manage NVMe drives. It's called nvme-cli.

  • How to Install FreeRADIUS and Daloradius on Ubuntu 20.04 – VITUX

    RADIUS is a AAA (authentication, authorization, and accounting) protocol that helps in controlling network access. In other words, RADIUS protocol is used for connection management between the Network Access Server (NAS) and Authentication server. The connection between two ends(NAC-NAS or NAS-Authentication server) is initiated after a successful negotiation on the network layer by exchanging packets containing necessary information such as NAS identification, authentication port number etc. In simple words, it can be said that RADIUS provides authentication, authorization, and account information from an Authentication server to a device requesting access.
