I use this quite a bit to modify binaries in shell script or makefiles when I'm prototyping. Decent example: https://github.com/SymbiFlow/prjxray/blob/6b7af3b1686b82773c9b09e0f2692196896b4dc1/minitests/partial_reconfig_flow/Makefile

I'm coming to CanSecWest for the first time in 2020 and I'm bringing "Finding Firmware Implants" training to the Dojo with me. https://cansecwest.com/dojos/2020/firmimplants.html

My day was spent in ISE 14.7. I could have been 8x as productive if it was multithreaded.

Ah, the winter holidays. The time when I inevitably overload myself with things like moving to another state, buying one house and selling another, tearing apart a car to send it off for bodywork restoration, and keep going at my day job. 😂😴
