Nix package manager on Fedora Silverblue

Warning

Disable composefs or enable root.transient before install and use nix on Fedora Silverblue 42. Do not mix both. Use just one method. I prefer enabling root.transient.

With `composefs` disabled

sudo sed -i 's/,ro//' /etc/fstab

sudo rpm-ostree kargs --append='ostree.prepare-root.composefs=0' --reboot

The Absolute State of Chat Reporting

Originally introduced in 1.19.1, chat reporting has undergone many changes in Mojang's attempts to eliminate the exploits and make the system functional. The purpose of this paper is to document the current technical state of chat reporting on an ongoing basis, and to provide a reference for the community to use when discussing the system. To that end I will try to keep it as unbiased as possible.

The Basics

Chat reporting heavily relies on cryptographic commitments and signatures to ensure that reported chat messages are not tampered with. The basic idea is that all players sign their chat messages with their private key, and then send the signature along with the message to the server.

Chat signing keypair is not generated by the client as one could expect; instead, it is issued by Mojang's services and is tied to the player's account. This means that the keypair is shared between all clients that the player uses, and the player can't change it. The keypair is f

Background

Workplaces may enforce TOTP 2FA to be enabled Office 365 accounts, which require the Microsoft Authenticator app to be installed.

Regular TOTP applications (such as Aegis, Authy, or LastPass) cannot be used as Microsoft uses a proprietary scheme called phonefactor. Furthermore, the application requires Google Services Framework (GSF) to be installed (likely to provide device notifications), and will refuse to work when it is not present on the device.

Forunately, after the registration is complete, the underlying mechanism the app uses to generate TOTP codes is regular otpauth, and its secrets can be exported with a little bit of effort.
