  • Katakana issue?
    Another interesting point: I copied both my answer and the suggested answer into diffchecker.com, and it said they were the same. Source: almost 3 years ago
  • 16.0.3 Prod Keys finally dumped
    Never knew diffchecker.com was a thing. Thank you so much for making me aware of it <3. Source: about 3 years ago
  • How to convince someone lossless compression is possible?
    In what way did you show the file comparison? Did you use a diff like diffchecker.com ? If someone can see for themselves that every bit of data between two files is exactly the same, and still thinks they are different, IDK how you could get past that. x == x is pretty fundamental. Source: over 3 years ago
  • Advanced Diff Checker?
    How do I find the actual difference between two strings that appear equal to the naked eye? I used multiple tools and some show no differences, but some show differences. I got diffs on diffchecker.com, but it just shows me that they are different, but not how they differ. Is there a better tool for this? Source: over 3 years ago
  • Is there a library that allows to easily do diffchecks between two json?
    I am wondering if there's something that allows you to easily display differences between two json like on diffchecker.com. Is there a library that allows you to easily do that? Source: almost 4 years ago
