Ouch. "Authors should: (1) not pick an important problem, (2) not challenge existing beliefs, (3) not obtain surprising results, (4) not use simple methods, (5) not provide full disclosure, and (6) not write clearly." journals.sagepub.com/doi/full/10.11…

I will repeat: PhD stipends are not supposed to be treated as salaries. You get paid while you are learning how to do research, as an RA. You get paid for learning how to teach as a TA.
PhD students do Teaching Assistantship and share teaching loads. Plus Research is work and it should be treated as work.

Check out this really cool binary patching tool developed right here in our lab @PurSecLab
I am happy to announce Patcherex2 (github.com/purseclab/Patc…), an easy-to-use, Python-based binary patching tool, designed to be extensible and compatible with multiple architectures. The code was mainly written by my student @__Han_Dai__ at @PurdueCS, for the DARPA AMP program.
