Also, don't miss this walk-through from last week:

Reverse-Engineering iOS Apps: Hacking on Lyft

My talk was also very introductory. Snakeninny's book covers a lot of things I didn't get to, including an introduction to ARM assembly, and how to reverse engineer components of iOS itself.

Why are they storing a binary file in a git repo? Every version of the file is stored, which makes it hard for anyone to quickly clone the repo. The repo is 261.9 MB large, even though the pdf is 16.4 MB. The file should be located in the "Releases" section.

Man that stuff really drives me crazy. Putting releases is one faux pas, and the inclusion of every library required to build the thing is the other one that burns me up.

I have been known to take a copy of reposurgeon to strip out the binaries and demonstrate to the repo owner how much smaller the repo would be if one were to make use of an actual release or build process. I would be glad to fix every one of them I come across, if I thought I had any prayer of having the repo owner accept the new slimmer version.

I've stripped the repo and now it's only 16M large

Thank you for this. Sharing your knowledge for anyone to enjoy and innovate upon is a great thing you're doing.
