I was googling for the tool I created last month called hexcompare. As it turns out, someone spoke a few sentences about it, and even included a picture of it working.
I could have turned to a FreeBSD system, but instead I decided Hexcompare was probably simple enough to compile by hand. It turns out the app was really simple, and I got it running quickly.
I wasn’t expecting anyone else to ever run it, much less indicating that they did so. That someone did was a huge compliment.
