    Crostini is an official feature built by Google that allows you to run Linux on a tightly integrated hypervisor inside Chrome OS. You keep a lot of Chrome OS’ security benefits while getting a Linux machine to play with.

    That said, no, it’s not illegal to install a different operating system on your Chromebook hardware. They are just PCs, under the hood. You might lose some hardware security features though, e.g. the capabilities provided by integration of the Titan silicon.

    If you had a job at Google, corporate IT would definitely not be happy if you wiped the company-managed OS and installed an unmanaged Linux distro :)



  • Tl;dr: TPMs are very unlikely to make your privacy better or worse, but they could definitely be abused by a company like MS to make end users’ experiences worse. They could also be used for significant security and privacy gains… they’re a tool.

    The TPM can be used to provide a cryptographic binding between aspects of your system’s configuration and a unique key which is resident within the TPM (a process called “attestation”). It can also generate secondary keys that are associated with the base key, and use those to do cryptographic operations like encryption/decryption and authentication.

    Telemetry wise, the TPM’s only utility might be to “prove” that the data sent from your PC wasn’t tampered with. That said, I don’t think MS is actually doing that, and they don’t need to in order to be incredibly invasive in their telemetry.

    The (imo) worst way in which a TPM might be abused in a user-hostile sense is to detect if the OS has been modified by the user, or if an installation isn’t legitimate, etc. That could be used to disable certain features if you try to install unauthorised software, dual boot Linux or whatever. This would be similar to the smartphones of today, which can for example disable access to banking apps if jailbroken/rooted.

    TPMs (>2.0 at least) otherwise have the potential to realise a significant improvement in security and privacy for users, if used correctly. They can be used for encryption and credentials that are bound in hardware and therefore practically impossible to steal. And can detect hardware tampering and potentially foil Evil Maid attacks. Imagine if your login sessions for various websites were bound to your hardware, such that a dodgy extension could never steal your cookies.












  • Looks like a very cool project, thanks for building it and sharing!

    Based on the formula you mentioned here, it sounds like an instance with one user who has posted at least one comment will have a maximum score of 1. Presumably the threshold would usually be set to greater than 1, to catch instances with lots of accounts that have never commented.

    This has given me another thought though: could spammers not just create one instance per spam account? If you own something like blah.xyz, you could in theory create ephemeral spam instances on subdomains and blast content out using those (e.g. spamuser@esgdf.blah.xyz, spamuser@ttraf.blah.xyz, etc.)

    Spam management on the Fediverse is sure to become an interesting issue. I wonder how practical the instance blocking approach will be - I think eventually we’ll need some kind of portable “user trustedness” score.
