✨Bringing light to #FileFormats ✨

Tough on the outside with food for thought inside!
File formats reveal a lot about the different meanings of an object.
CPP-008 and CPP-010 help you uncover them through #FileFormatIdentification and #FileFormatValidation:

Revisiting bsdiff as a tool for digital preservation

by @beet_keeper

I introduced bsdiff in a blog in 2014. bsdiff compares the differences between two files, e.g. broken_file_a and corrected_file_b and creates a patch that can be applied to broken_file_a to generate a byte-for-byte match for corrected_file_b.

On the face of it, in an archive, we probably only care about corrected_file_2 and so why would we care about a technology that patches a broken file?

In all of the use-cases we can imagine the primary reasons are cost savings and removing redundancy in file storage or transmission of digital information. In one very special case we can record the difference between broken_file_a and corrected_file_b and give users a totally objective method of recreating corrected_file_b from broken_file_a providing 100% verifiable proof of the migration pathway taken between the two files.

They really fucked up with the new #fileformats. Why even call it #webp. Just put the #png extension on it and no one would have to know if you made it backward compatible, your moronic apes. Just put #jpeg at the end of #jxl files.

Dumbass engineers they should hire me. I could have told them this.
