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.

Sad news for the #eurovision  Grand Final:

My local broadcaster reached out again and told me that the bad audio mix is (at least partly) due to EBU rules. Specifically, the LFE channel isn't allowed to be used in competing songs.

This must be a new rule, since my #ESC2024  recording has full 5.1 audio, even during the acts. Sounds much better in comparison, in my opinion.

I again recommend reaching out to your broadcaster to get that changed at the EBU level for next year.

Greetings from Denver! This week we are at the American #Meteorological Society #AMS conference for #Polar Meteorology and Oceanography with amazing presentations from #MOSAiC and #AC3 (https://www.ac3-tr.de/).

Hello fellow #eurovision  watchers!

During the first semi-final yesterday, I noticed that the German broadcast had no LFE channel output during the acts, only in-between. Audio mixing of the acts also felt sub-par overall.

Did you experience similar problems with your broadcasters?

Yesterday I saw my first #polarlights in Hyytiälä during my Winterschool for #AC3

Was a very nice view, would do again!

Our #virga sniffer workshop at the joint #IRTG #AC3 #uniHelsinki winter school on causes, contributions and trends to #ArcticAmplification in #Hyytiälä started yesterday with a comprehensive introduction. [af]
