PX4-Autopilot VS chipshouter-picoemp

They are widely used in narrow circles :)

Two of (arguably the best) open source RC aircraft flight controllers (ArduPilot and PX4) are using extended Kalman filters in their state estimators (essentially sensor fusion that provides attitude/position estimate):

I'm not that familiar with cleanflight/betaflight/inav scene to know what the FPV racer flight controllers use.

Actually, even the General Aviation pilots who actually manually manage their own load-shedding during a mission would quite like automated power distribution and management systems... and if you felt like taking on that sort of work as a hobby project to cut your teeth, I bet the guys at the (open-source) PX4 project would bite your hand off...

As a flight pilot engineer you have to find a sweet spot and balance logging too much and too little. Writing logs to an SD card has huge costs that come with it, that's why you don't want to log too much. Logging too little and you can't debug issues later on properly.

PX4 also has lots of "topics" logged at around 1/10, e.g. hover thrust estimate every 100ms:

Okay, but nowadays most people talk about “Pixhawk” as an open-standard hardware platform and PX4 as the software. The source code is at https://github.com/PX4/PX4-Autopilot and they call themselves “PX4 Autopilot Software”.

As an example, PX4 is a popular open source drone autopilot software: https://github.com/PX4/PX4-Autopilot

I am working as a Remote Embedded Software developer for quite a while now and there is no obstacle in Remote work. If I am missing anything, parts are arriving in under the week. That said, I never had a better work-life balance in the last 10 years. Anyone who said Embedded is not possible to do remotely just check any open source flight controller project (in my case PX4).

Replicant: Reproducing a Fault Injection Attack on the Trezor One This article does a great job at introducing the reader to fault injection. What is a fault injection? What are the common technics to do a fault injection? By the end of the article, you'll get answers to these questions and, of course, all the details on how to apply them on the Trezor One. A second part is planned to show how the same attack can be done with the PicoEMP, a low-cost Electromagnetic Fault Injection (EMFI) tool.
