I finally took the time to distill my key research projects on my website with diagrams and artifact links. I'm really proud to have led and worked on so many exciting and challenging projects across the firmware, systems, and mobile security spaces.

The most challenging part of writing "The Secret Life of Circuits" wasn't the writing process. It was crafting over 290 full-color illustrations on my own design.

I think they set the book apart. For a no-strings-attached sample chapter, check out: https://t.co/wEtSu2xiUN

@alkalinesec Do you have a sense of what this solver is doing so much better than others?

[Grant H @Digital_Cold]

Okay gave it a good soak. Not sure if I fully reflowed it but the connection is stable now. Will wait for it cool down before I call it done

Got a new monitor to be more productive and of course it doesn't work out of the box when combined with my KVM and the Intel i915/Xe driver. Multiple hours later learning about EDID and i2c and the problem is "fixed" (debugfs edid_override), but now I'm trying to figure out KVM firmware updates...

[Grant H @Digital_Cold]

Huh I guess it's time to reflow the board.
