  • mesa 20.2.0
    Hi list,
    
    After a long wait, mesa 20.2.0 is now available. This is the first stable
    release of the series, but it's also been a very long time since the last
    release, and as such I'd like to reiterate that those looking for the most
    stable experience will likely want to wait for mesa 20.2.1.
    
    I'm back to the office and finally getting back in the swing of things after a
    long vacation, so expect more regular releases for the 20.2 series from here on
    out.

  • Mesa 20.2 Released With RADV ACO By Default, Initial RDNA2 Graphics Support

    Mesa 20.2 has managed to release just before the end of the the quarter. This Mesa Q3'2020 graphics driver update is coming out about one month behind schedule but the wait is worthwhile given many open-source OpenGL and Vulkan driver updates.

    There is new GPU support, RADV is using the ACO shader compiler by default, much better LLVMpipe OpenGL support, new Vulkan extensions, and much more.

  • Open source graphics drivers get a boost with Mesa 20.2.0 out now

    The latest and greatest in open source graphics drivers has released with Mesa 20.2.0, although you should wait on it if you're after a stable experience.

    As always, the Mesa team suggest waiting on at least the first bug fix release with Mesa 20.2.1 which is usually out within a few weeks. Developer Dylan Baker who announced the new release mentioned to expect some more regular releases for the 20.2 series, as they're back from a long vacation.

    What's new? Lots, as always. Support for new Vulkan extensions, added support for new GPUs including initial work done for AMD's upcoming RDNA 2 noted as "gfx10.3", expanded GLES 3.2 and OpenGL 4.5 support for LLVMpipe, lots of work on the Panfrost driver for Mali GPUs. You can find some release notes for Mesa 20.2.0 here.

Mesa 20.2.0 Is Released

  • Mesa 20.2.0 Is Released

    There is a lot to of new features in the latest Linux graphics stack. Mesa 20.2 offers Vulkan 1.2 support, OpenGL 4.5 support for llvmpipe, faster NIR performance and the ACO shader compiler for Vulkan on AMD hardware is now the default shader compiler for the AMD RADV Vulkan driver.

  • How To Install HAProxy on CentOS 8 - idroot

    In this tutorial, we will show you how to install HAProxy on your CentOS 8. For those of you who didn’t know, HAProxy is a free HTTP/TCP high availability load balancer and proxy server. It spreads requests among multiple servers to mitigate issues resulting from a single server failure. HA Proxy is used by a number of high-profile websites including GitHub, Bitbucket, Stack Overflow, Reddit, Tumblr, Twitter, and Tuenti, and is used in the OpsWorks product from Amazon Web Services. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step by step installation HAProxy on a CentOS 8.

  • YAML for beginners | Enable Sysadmin

    YAML Ain't a Markup Language (YAML), and as configuration formats go, it's easy on the eyes. It has an intuitive visual structure, and its logic is pretty simple: indented bullet points inherit properties of parent bullet points. But this apparent simplicity can be deceptive. It's easy (and misleading) to think of YAML as just a list of related values, no more complex than a shopping list. There is a heading and some items beneath it. The items below the heading relate directly to it, right? Well, you can test this theory by writing a little bit of valid YAML.

  • colorls – turbocharged alternative to ls

    The part of the operating system responsible for managing files and directories is called the file system. It organizes our data into files, which hold information, and directories (also called ‘folders’), which hold files or other directories. Several commands are frequently used to create, inspect, rename, and delete files and directories. One of these commands is ls, which prints the names of the files and directories in the current directory. A directory is really just a file. It’s a special file with special rules. The ls utility appeared in the first version of AT&T UNIX. Are you looking to liven up your shell? Want a bit more beauty on your terminal? colorls might be the ticket. colorls is a command-line utility that aims to improve on ls. color is written in Ruby.

Linux Patches Aim To Provide Fork'ing Brute Force Attack Mitigation

Building off a set of "request for comments" patches from September, a set of patches were sent out on Sunday for providing brute force attack mitigation around the fork system call. With attacks aiming to break Address Space Layout Randomization (ASLR) and similar attacks often relying on the fork system call in order to keep replicating the memory contents of the parent process, these patches aim to detect the behavior where fork is being exploited for these nefarious purposes. This work is inspired in part by some patches carried by GrSecurity where a delay around the fork system call will be imposed if a child died from a fatal error. These patches propose collecting statistical data shared across all the processes with the same memory contents and analyzing the timing of any children processes crashing. When the code determines such an exploit may be underway leveraging fork, all of the processes using the same memory contents are killed to stop whatever malicious activity may be happening.

Manage content using Pulp Debian

Pulp is an open source repository management tool that helps you fetch, mirror, upload, and publish content within your organization. It can be used to manage various types of content such as software packages (from RPM packages to Ruby gems), as well as Ansible collections, container images, and even arbitrary files. A typical workflow starts with fetching software packages from an existing repository (for example, http://mirror.centos.org/centos/7/os/x86_64/) or adding packages manually (for private packages built within your organization). Then Pulp helps you make arbitrary collections of software packages that are consumable by clients. With it, you... Read more
