Trigon: Exploiting coprocessors for fun and for profit (part 2)

news.ycombinator.com Alfie Cg 2025-07-22 13:15:26

A few months ago, I released a kernel exploit called Trigon. It was significant in that it was deterministic - that is, it cannot fail.

For years, it was reported that the government had sold the album directly to PleaserDAO, a crypto collective that specializes in NFTs. However, Bloomberg now reports that

Kaitlyn Cimino / Android Authority After years as a power-draining setting with significant limitations, the always-on display on Wear OS smartwatches is finally getting a glow-up.

Google Pixels are no longer the AOSP reference device

With the launch of Android 16 earlier this week, Google did not release the Pixel hardware repos and device trees that are particularly important for custom ROM developers. This led to speculation by some that “AOSP is being discontinued.” Google has denied that, but the Pixel change does look to be intentional. On Tuesday, Google released Android 16’s source code to the Android Open Source Project (AOSP). However, the Pixel device trees and other code used to adapt the AOSP release to specific

Mishaal Rahman / Android Authority TL;DR Google has made it harder to build custom Android ROMs for Pixel phones by omitting their device trees and driver binaries from the latest AOSP release. The company says this is because it’s shifting its AOSP reference target from Pixel hardware to a virtual device called “Cuttlefish” to be more neutral. While Google insists AOSP isn’t going away, developers must now reverse-engineer changes, making the process for supporting Pixel devices more difficu
