> .. he ended up working for Apple. There he worked on securing all the lesser-known firmwares on Macs and peripherals - everything from 3rd party GPUs to SecureBoot for monitors! He worked on the x86-side of the T2 SecureBoot architecture, and his final project was leading the M1 SecureBoot architecture - being directly responsible for designing a system that could provide iOS-level security, while still allowing customer choice to trust arbitrary non-Apple code such as Linux bootloaders. He left Apple in Dec 2020 after the M1 Macs shipped, so he could work full time on Open Security Training.

Even if it seems like it's outdated somewhat due to the breakneck progress of machine learning in the past few years the legendary Cs231n is still the course to start your ML journey with. Especially as taught by Andrej Karpathy. You should be able to find recordings of it on YouTube. Make sure you get the ones from Karpathy years at Stanford. As brilliant as Andrej is as a ML practitioner, he is an absolute world class mastermind at teaching this stuff.

Android/Kotlin course on Udacity, by Google: https://www.udacity.com/course/developing-android-apps-with-...

This one is slightly out of date, but it's great, something I'd happily pay $300 or so for. The value is heavily subsidized by Google. I have taught week-long Android professional certifications and this does a lot better than most of them out there.

I would like people to add paid courses. I don’t mind paying $500+ if it’s really well done

CS50 is nice.
