Hello! I was able to do a fire talk @ Drexel CCI in the Rush building last night. It was fresh to get feedback from people, sharing my presentation and getting to see everyone else present and to chat with people.
If you would like some slides about the use of dd, sha256sum and exiftool, you are welcome to the slides.
For fun, you can run exiftool on this ppt, exported from LibreOffice.
