There is a small bug in the signature verification of OTA packages in the Android Open Source Framework. Official builds doing normal double verification of packages are not vulnerable but OEMs and third party apps may be. Jérémy Jourdois explains it here: blog.quarkslab.com/aosp_ota_sig...

Digital vs film X-ray . Film offers higher resolution and better dynamic range with the same settings, but slightly longer exposure time (and more tedious image acquisition). Comes in handy when it comes to tiny electronics. Images of an Abbott Lingo continuous glucose monitor.

I'm trying to think of a good way to flex Poststation as a demo for the embedded world booth. Does anyone have ideas of fun, interactive, and maybe mind bending things to have 8-16 independent MCUs do? I plan to fit it all into a eurorack case, as individual cards/modules.

I’ve published CLUES (Custom Lightweight UUID Exchange Schema) and my current data about Bluetooth custom UUIDs to its own repository so that it can easily be incorporated as a git submodule in other research projects. https://github.com/darkmentorllc/CLUES_Schema

Today I used a vinyl sticker from a conference in the place of heatshrink or electrical tape. Gotta do what you gotta do. Can't have this stuff shorting out!

I just disabled Android "Quick phrases" for my alarm clock app after realizing it's causing alarms to be ineffective. Who came up with this feature??? Why is it on by default?? Ensh**tification much?? Is there a class action suit I can join??

Digital license plates, legal to buy in some states and drive with nationwide, can be jailbroken. Hackers can install new firmware in minutes, then change plate numbers via a Bluetooth app to evade surveillance, tolls and tickets—or make someone else pay. www.wired.com/story/digita...

Picking up from last week's thread on overclocking the #RP2350, I'm going to be pushing this Pico 2 further tonight. To start with, I'm doing a run of tests at 576MHz and 1.7V, to see how much difference the cooling has made.

A perfectly sensible setup for doing perfectly sensible things.

If you're looking for a good time programming, I recommend #adventofcode Day 6. Part 2 took me 4 tries to get a correct and performant solution.
