Kernel Recipes 2013 - Easy rootfs using BuildrootAnne Nicolas
The Linux kernel is an exciting world. But if you want to get a working system, it is still essential to provide our kernel a root filesystem. The kernel developers often struggle to find a simple rootfs, adapted to their architecture, together with the tools that fits properly.
We will present how Buildroot, a tool for building embedded Linux systems, can meet the needs of kernel developers in the build of minimal rootfs for their developments.

Benefits of Linux
Linux is "Open Source", which means that anybody can build their own, slightly different, versions of Linux using the same underlying programs. People gather together their own choices of these programs and offer them to the world.
Linux is a system that converts a powerful but mindless heap of silicon into something that an ordinary user can control, and which can run programs written to a common standard.
Linux can be made even more powerful when it's packaged with GUI's, other tools and utilities.
Different people can change this code to make the system better, and even sell it if they want.
If you are technical person who enjoys technology, you can’t beat the freedom it gives you. If you are not a technical person then, once set up, you will have a more stable, reliable and secure system.
The real benefit of Linux’s community approach to software, is that the community is made up of different individuals with different tastes, etc; many of whom are developers. This means that your own installing on your system can be incredibly personal and to your tastes.
The freedom of being open source is that you are completely 100% sure of what is running on your system. In terms of privacy that is pretty good. You know that there is nothing that is spying on you for advertising, marketing and other sinister companies.

Linux Derivative Recommendation
For an all-round rock-solid experience for general use, Debian is the best due to its universal nature.
It runs it 10 different architectures and comes with a huge (the biggest, actually) collection of pre-compiled software in its repositories, ready to install.
Based on what packages you install or remove, you can totally transform an already installed Debian to be most suited for any kind of work.
I recommend Debian simply because it can be the best choice no matter what you want to use it for.
It is also good for network servers, popular for personal computers, and has been used as a base for many other distributions.
Arch Linux is that your system is exactly what you make it - you decide exactly which packages you want. The end result of this is that your system is custom tailored to your computing experience and necessities. This also has the added advantage of being an extremely flexible distro.
With Arch Linux, you have unlimited choices for every aspect of your machine. If you are a proponent of Free Software, you can elect to only use free packages. If you don't want or need a full desktop environment, you can elect to use a minimalistic window manager.

Linux Graphical Interface
When it comes to a GUI on Linux, you have a number of options and most of the distros offer multiple GUI version built in.
So depending on your taste, you’re not spoiled for choice; making your question rather redundant.
X (also called X11) is responsible for GUI in Linux.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

29. Introduction to APT
"In the beginning there was the .tar.gz. Users had to compile each
program that they wanted to use on their GNU/Linux systems.
When Debian was created, it was deemed necessary that the
system include a method of managing the packages installed on
the machine. The name dpkg was given to this system. Thus the
famous 'package' first came into being on GNU/Linux, a while
before Red Hat decided to create their own 'rpm' system.
A new dilemma quickly took hold of the minds of the makers of
GNU/Linux. They needed a rapid, practical, and efficient way to
install packages that would manage dependencies automatically
and take care of their configuration files while upgrading. Here
again, Debian led the way and gave birth to APT, the Advanced
Packaging Tool, which has since been ported by Conectiva for use
with rpm and has been adopted by some other distributions."
