Top Lightweight Linux Distros
Lubuntu, Xubuntu, CrunchBang, Peppermint, and Puppy Linux are some of the top lightweight Linux distributions that can run well on older computers with low system requirements. A lightweight distro uses few system resources and focuses on speed and efficiency. Lubuntu and Xubuntu use the LXDE and Xfce desktop environments respectively, keeping their requirements low. CrunchBang offers a modern Debian system without sacrificing performance using the Openbox window manager. Peppermint is based on Lubuntu but is cloud-centric, while Puppy Linux can run entirely from RAM.
The Shell Game Part 1: What is a shell?
This document provides an introduction to shells in Linux and Unix-like operating systems. It defines what a shell is, explaining that it is a program that provides the user interface through which commands can be typed to interact with and run programs on the operating system. It notes that servers commonly only use the shell interface without a graphical user interface to save resources. It discusses how shells are used for server administration tasks over secure shell (SSH) connections and why the shell interface is more powerful and efficient than a GUI. It encourages new users to take notes on useful commands they find.
The Shell Game Part 2: What are your shell choices?
The document discusses different types of shells available in Linux systems. It describes the original Bourne shell and the default Bourne-Again shell (bash). It also covers other shells like the Almquist shell, C shell, Korn shell, TENEX C shell, and Z shell. The document notes that users can temporarily switch shells or permanently change their default shell using the chsh command. Choosing different shells allows customizing capabilities to a user's preferences or system requirements.
linux_distro
This document outlines a plan to build a customized Linux distribution based on Ubuntu from scratch. It discusses using Ubuntu 8.10 to build the distribution, tools needed like debootstrap and binutils, including a lightweight desktop environment and LAMPP server, creating a local software repository, modifying artwork, and ultimately producing a bootable live CD with the customized Linux distro. The goal is to get experience building a own Linux distribution and live system.

Time-sharing systems allow multiple users to share a single computer simultaneously. The operating system switches between programs rapidly, giving each program a short time slice or time quantum to execute before switching to another program. This creates the illusion for each user that they have sole use of the computer and increases CPU utilization and overall system throughput.
Linux usb2ether
The document discusses Linux USB driver development, providing an overview of USB specifications, the USB data flow model, USB transfer types, and the structure of USB drivers in the Linux kernel, including standard driver interfaces and how drivers interact with the USB subsystem.
USB protocol
This document provides an introduction to USB (Universal Serial Bus). It discusses the original motivations for USB including flexibility, ease of use, and high speed data transfer. It describes the different USB speeds and the star topology of the USB bus. It explains that USB uses a host-controlled model and supports up to 127 devices connected at once. The document also covers USB packets, transactions, functions, endpoints, pipes, and the different types of transfers (control, interrupt, bulk, isochronous).
Usb universal serial bus
This document provides an overview of USB, including its history and key versions. USB (Universal Serial Bus) allows connection of peripherals to computers. It has evolved from USB 1.0 with 1.5Mbps speeds to USB 2.0 at 480Mbps to the latest USB 3.0 offering data transfer rates up to 4.8Gbps. USB 3.0 features a single connector type, hot swapping, plug and play functionality, and high performance speeds. It supports connection of storage drives and other peripherals.

Code review
This document discusses several code review systems including Gerrit, GitHub Pull Requests, and Phabricator. It provides more detail on the Phabricator workflow, which involves an author preparing a change and sending it for review to specified reviewers. The reviewers then inspect the change, discuss it, request changes, or approve it. The author may update the change in response to feedback until it is accepted and pushed to the upstream codebase.
Refactoring
This document discusses principles of refactoring including defining it as modifying code without changing external behavior, origins with Ward Cunningham and Kent Beck, and reasons for refactoring like improving design and finding bugs. An example of renaming a method is provided along with steps. Additional refactoring techniques like extracting methods are presented. The conclusion emphasizes keeping code easy to change through refactoring and having tests first.
MCU compare

The choice of an operating system plays a pivotal role in shaping our computing experience. For decades, Microsoft's Windows has dominated the market, offering a familiar and widely adopted platform for personal and professional use. However, as technological advancements continue to push the boundaries of innovation, alternative operating systems have emerged, challenging the status quo and offering users a fresh perspective on computing.
One such alternative that has garnered significant attention and acclaim is Nitrux Linux 3.5.0, a sleek, powerful, and user-friendly Linux distribution that promises to redefine the way we interact with our devices. With its focus on performance, security, and customization, Nitrux Linux presents a compelling case for those seeking to break free from the constraints of proprietary software and embrace the freedom and flexibility of open-source computing.
Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
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:

Cosa hanno in comune un mattoncino Lego e la backdoor XZ?
ABSTRACT: A prima vista, un mattoncino Lego e la backdoor XZ potrebbero avere in comune il fatto di essere entrambi blocchi di costruzione, o dipendenze di progetti creativi e software. La realtà è che un mattoncino Lego e il caso della backdoor XZ hanno molto di più di tutto ciò in comune.
Partecipate alla presentazione per immergervi in una storia di interoperabilità, standard e formati aperti, per poi discutere del ruolo importante che i contributori hanno in una comunità open source sostenibile.
BIO: Sostenitrice del software libero e dei formati standard e aperti. È stata un membro attivo dei progetti Fedora e openSUSE e ha co-fondato l'Associazione LibreItalia dove è stata coinvolta in diversi eventi, migrazioni e formazione relativi a LibreOffice. In precedenza ha lavorato a migrazioni e corsi di formazione su LibreOffice per diverse amministrazioni pubbliche e privati. Da gennaio 2020 lavora in SUSE come Software Release Engineer per Uyuni e SUSE Manager e quando non segue la sua passione per i computer e per Geeko coltiva la sua curiosità per l'astronomia (da cui deriva il suo nickname deneb_alpha).
