The slides from my @0x41con 2023 talk are now available: https://t.co/SpBoAhGA2X They were primarily designed to supplement my speaking (and the PDF doesn't have animations), but you may still find them useful. Reach out if you have questions.

Still a WIP, but should be useful so far. Would also like to look into how microkernel iBoot works some more and see if there's any improvements that can be made there.

For whoever might be interested, finally got some time to put together an iBoot & SecureROM loader for both Binary Ninja and IDA that maps segments (TEXT, CONST, DATA, BSS) correctly: https://t.co/OKl8QZbW3T

Search continues to be a bit of a nightmare—one day I'll write a better library but for now I'll keep fighting Pagefind... P.S. If anything seems wonky, try emptying your cache.

Two new https://t.co/N7QuyNLMGm updates: - the search bar should now return better results thanks to better page indexing; and - when it doesn’t, there are now “all instructions” and “all registers” pages you can CMD+F manually.

I like em dashes, and I hate that some people now take them as evidence of text being AI generated.

Quick note: https://t.co/fg5gX3QJsd has been updated to the latest version of the Arm spec. Any changes should be strictly improvements, but let me know if something seems off.

Yep, it's official: 0x41con and SAFACon Party will be held back to back in Belgrade this year, in an epic venue. You know the drill: you send in the talks, I send out the invites.
