Me fucking about with an LTE hotspot ended up helping enable an EFF project that's then turned into a Wired story about mass surveillance around the DNC, so never stop fucking about with things: https://www.wired.com/story/2024-dnc-cell-site-simulator-phone-surveillance/

@david_chisnall @cesarb @tthbaltazar This differs between ARM and x86 - I don't think any x86 fTPMs run on the AP, they're either on the ME (Intel) or PSP (AMD) so fairly decently segregated. ARM implementations are generally in Trustzone so there's a very different set of issues.

A more detailed writeup of how the FSF is not only wrong about TPMs being involved in hardware-based DRM, they missed the actual user-hostile hardware DRM implementation: https://mjg59.dreamwidth.org/70954.html

Nice hacker culture you've got there

Standing offer: got a fix for a Linux kernel issue and don't want to engage with LKML? Convince me that it probably makes sense and I'll deal with the bullshit for you

"Today, most of the major streaming media platforms utilize the TPM to decrypt media streams, forcefully placing the decryption out of the user's control." (from https://www.defectivebydesign.org/dayagainstdrm) I… just… what? This isn't even slightly true. There's plenty of good reasons to object to Microsoft imposing hardware requirements on Windows 11 that aren't strictly required, but *nobody* is doing media decryption on a TPM because TPMs are nowhere near fast enough to do that

Safely through security at Heathrow for the last time this year, next border crossing will be by land so I'm fairly sure I'm in the clear good work everybody

Visited my old college and admired the sign describing how the Church of England is forcing them to keep displaying the memorial for a guy who made a fortune in the slave trade when they'd really prefer not having it in the chapel

Update: I am in the UK but accidentally left my (honestly kind of scratchy and also a decade old) scarf on the plane so who can really say who's the winner here

Getting on my final flight to the UK for the year shortly, so if anyone's invested in me failing the "Matthew doesn't get arrested entering the UK challenge 2024" then you've got about 4 hours until I arrive at Heathrow

(look at the FSF's involvement in releasing a new version of the GFDL to allow Wikipedia to transition to CC for precedent)

Irregular reminder that Oracle could, if they wanted, release a new version of the CDDL that explicitly made almost all of OpenZFS GPL-compatible and that's something people could have lobbied for instead of trying to make arguments that it's actually GPL-compatible if you squint hard enough

Incredible scenes as an FSF voting member (the people who choose the board) ignores an explicit request from someone to stop replying to them, tells them to block him instead, and then claims that if they reply to *him* then they're the real abuser https://gnusocial.jp/conversation/4188829#notice-8198659

Hello I wrote a thing about how Android made a good privacy improvement and in the process apparently made key attestation far less useful for certain use cases https://mjg59.dreamwidth.org/70630.html

Today's discovery: gcc will remove calls to memcpy() with a len of 0 (good), knows it's UB to call memcpy() with a dest of NULL (spec compliant), will assume that dest can't be NULL (fucking compilers, man), will combine both to engage in this UTTERLY PATHOLOGICAL BEHAVIOUR https://godbolt.org/z/bGqM6arGT
