Distrusts computers. Keeps embracing them anyway. Previously: Golem Foundation/Wildland, Qubes OS, hardware/virtualization/OS security research.

The Digital Services Act and Theories of Power

The European Commission put a 120M EUR fine on X for DSA violations. But as the European politicians cannot get themselves to leave the platform, it shows the issues with how they understand how power works on social platforms.

The State Department’s X Directive and the End of Platform Independence

A cable endorsing a social media platform by name as a tool of U.S. diplomacy and  military psychological operations would have been unthinkable—until recently.

Protocols, Not Platforms: A Technological Approach to Free Speech

What is clear is that there is no simple solution to these challenges, and most of the ones that are normally presented tend not to deal with the reality of the problems or to understand the technical and societal challenges that likely make them impossible.

Xen Project FAQ Compatibility - Xen

Platform as a Runtime - the Next Step in Platform Engineering

As systems become larger and more complex we need to take the concepts of platform engineering to a higher level – to the code level – by creating platforms and abstractions that will reduce cognitive load, help simplify and accelerate software development, and allow for easy maintenance and upgrades to the platform. Let’s move from “platform” to “Platform as a Runtime”.

There is no ethical case for staying on X

X has crossed a line it cannot uncross. This is no longer a debate about moderation or free speech trade-offs, but about predictable harm enabled by design. When a platform becomes ethically indefensible, outrage is not enough – walking away matters.

Platform Studies

The Platform Studies book series has been established to promote the investigation of underlying computing systems and how they enable, constrain, shape and support the creative work that is done on them. The series investigates the foundations of digital media — the computing systems, both hardware and software, that developers and users depend upon for artistic, literary, and gaming development. Books in the series will certainly vary in their approaches, but they will all also share certain features: A focus on a single platform or a closely related family of platforms; Technical rigor and in-depth investigation of how computing technologies work; An awareness of and discussion of how computing platforms exist in a context of culture and society, being developed based on cultural concepts and then contributing to culture in a variety of ways — for instance, by affecting how people perceive computing.
