  • Sometimes it's best to use the official upstream versions of software

    There are a number of things that make this less alarming than it looks, somewhat mitigating the problems I pointed out. First, both Prometheus and Grafana actually do provide official binary builds, and in fact it's the default way to use each project. That it's the default way means that each project has a relatively strong motivation to make good releases (and fix problems promptly), especially when combined with the development pace. When a new Grafana or Prometheus release comes out, each project knows that a lot of people will be updating to their provided binaries and they cannot sort of wash their hands of any problems that show up.

  • Why should you work on free software (or other technology issues)? | Life on M

    A world in which all technology is just cannot exist under capitalism. It cannot exist under racism or sexism or ableism. It cannot exist in a world that does not exist if we are ravaged by the effects of climate change. At the same time, free software is part of the story of each of these. The modern technology state fuels capitalism, and capitalism fuels it. It cannot exist without transparency at all levels of the creation process. Proprietary software and algorithms reinforce racial and gender injustice. Technology is very guilty of its contributions to the climate crisis. By working on making technology more just, by making it more free, we are working to address these issues. Software makes the world work, and oppressive software creates an oppressive world.

  • Pulling changes from GitHub to Git - The Linux Juggernaut [Ed: Careful not to conflate Microsoft proprietary software with Git, which is Free software. Git is not GitHub.]

  • List of Commands to get Linux system info using terminal - Linux Shout

    In Linux, we can use the command terminal to check various system hardware configurations and information such as CPU, Memory, hard disk, etc., and here are those to use… Although there are tools that can display Linux system info graphically, however, here we are going to use the inbuilt commands.
