When you were partying, I studied the hardware-backed key. When you were having pre-marital sex, I mastered the platform certificate. While you wasted your days at the gym in pursuit of vanity, I cultivated key attestation. And now that the world is on fire and the barbarians are at the gate you have the audacity to come to me for help.

I understand that adding complexity isn't free, but how does enabling Atmos audio output on this Xbox result in an extra 200ms of audio latency and how do I figure out which component in the chain is responsible for it? I'm now wondering whether I'd be better off disabling game mode on the TV in order to introduce more video latency to balance it out…

tfw your picture frame forgets which art it's supposed to be displaying and resets to defaults

@antnisp Not really if I'm targeting an ESP32

Thought I was going to have to handle JSON in C++ and then realised that I can actually pre-process it somewhere else in a sensible language and phew that makes everything much easier

Is there really no Linux incremental backup solution that includes encryption in the way Time Machine does and no I do not want three rsyncs in a trenchcoat thank you

the cpu is very tired. it is eepy. the cpu has had a very long day of leaking data and wants to take just a small sleep. it eeby and neebies to sleebie. cpu sleepy and need bed by time. the cpu is currently experiencing critical levels of being a sleehjy little guy and needs to go to beb.

This is what we refer to as "Race to idle", the idea that CPUs are more power efficient if they exhaust their workload in the shortest timeframe possible and then enter a low power state. In this essay I will

No Wire-Nut November (buying Wagos)

Disproportionately more enthusiastic about working for companies that sponsor childcare at conferences

Extremely confused by people who see WSL as an attempt to compete with Linux and not an attempt to prevent developers moving to macos

Current status: at 37,000 feet and a flight attendant has just determined that someone threw a cigarette stub into a trash can somewhere but language barriers are making it hard to figure out where so things could be going better

Why don't more dishwashers have observation windows like this adorable boi

Binder is a large chunk of complicated code that exposes a fairly large attack surface to userland and replacing the implementation with one in Rust is a huge step forwards in improving the security of platforms that require it: https://lore.kernel.org/lkml/20231101-rust-binder-v1-0-08ba9197f637@google.com/

@bsdphk you want to put one of those in-kernel?

@mwhudson there's no inherent reason not to have a standard way to read that from the firmware or first-stage bootloader (effectively equivalent)

@azonenberg It being entirely in the EC would be basically equivalent to ACPI except we'd have less insight into what's going on behind the scenes

@azonenberg The EC doesn't have access to the CPU's buses, SMM does.

@josh @stark And, well, the fundamental problem is still that you need to identify all possible scenarios people might reasonably want to implement in advance, and it's clear the industry isn't interested in that

@josh @stark Intel tried https://en.wikipedia.org/wiki/Simple_Firmware_Interface and basically nobody was interested
