172,000 index cards * 150 words / card [average maximum, using front only] * 1,200 bytes / 150 words [rough average with Unicode encoding] * 1 kb / 1024 bytes * 1MB/1024 kb = approximately 200 MB of text storage

Having it well organized and indexed… Priceless.

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.
