Solene'% : Introduction to Qubes OS when you do not know what it is

Hello, Operator!

Part of the WonderOS project, this is presented as the operating manual that would come with the reader’s first machine running WonderOS. It is an exercise in exploring how people familiar with mainstream personal computing devices and systems would become computer literate in an itemized environment. It is written as though the reader is familiar with today’s mainstream operating systems, and is exploring their first itemized OS.

The Virtual OS Museum

Over 1,700 pre-installed operating systems spanning 1948 to today, in a single Linux VM. Bundled QEMU, VirtualBox, and UTM. One-click launchers for Windows and Linux.

TrenchBoot Anti Evil Maid (current plan - v2) - Dasharo Universe

As Qubes OS users, promoters, and developers, we understand how essential it is to be aware of the latest developments in maintaining the security of your favorite operating system. We're excited to share our plans to integrate the TrenchBoot Project into Qubes OS's new Anti-Evil Maid (AEM) implementation. As you may know, traditional firmware security measures like UEFI Secure Boot and measured boot, even with a Static Root of Trust (SRT), may only sometimes be enough to ensure a completely secure environment for your operating system. Compromised firmware may allow for the injection of malicious software into your system, making it difficult to detect. To overcome these limitations, many silicon vendors have started implementing Dynamic Root of Trust (DRT) technologies to establish a secure environment for operating system launch and integrity measurements. We're excited to take advantage of these advancements through integration with the TrenchBoot Project.

Genode - Genode Operating System Framework

We understand the complexity of code and policy as the most fundamental security problem shared by modern general-purpose operating systems. Because of high functional demands and dynamic workloads, however, this complexity cannot be avoided. But it can be organized. Genode is a novel OS architecture that is able to master complexity by applying a strict organizational structure to all software components including device drivers, system services, and applications. The Genode OS framework is an open-source tool kit for building highly secure component-based operating systems. It scales from embedded devices to dynamic general-purpose computing.

Was feeling cranky about all the people claiming they’re building an “AI OS,” so… I vibe coded an AI OS. Meet Llanux, a custom Linux distro that boots to llama.cpp. No GNOME/KDE, just a chat TUI, local inference, and a model downloader.

We're excited to announce a major architectural improvement to Atuin Desktop: a completely redesigned runbook execution engine.

What does OSWorld tell us about AI’s ability to use computers?

We review OSWorld, a prominent computer use benchmark. Tasks are relatively simple, many don’t require GUIs, and success often hinges on interpreting ambiguous instructions. The benchmark is also not stable over time.
