Now what ? #AC3 audio seems to use system provided decoder and for some reason my new laptop does not have that ? Not that I need it *that* much, only an old camcorder seems to use that but still.

Revisiting bsdiff as a tool for digital preservation
by @beet_keeperI 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.

The sensitivity index: Corrupting Y2K
by @beet_keeperIn December I asked “What will you bitflip today?” Not long after, Johan’s (@bitsgalore) Digtial Dark Age Crew released its long lost hidden single Y2K — well, I couldn’t resist corrupting it.
Fixity is an interesting property enabled by digital technologies. Checksums allow us to demonstrate mathematically that a file has not been changed. An often cited definition of fixity is:
Fixity, in the preservation sense, means the assurance that a digital file has remained unchanged, i.e. fixed — Bailey (2014)
It’s very much linked to the concept of integrity. A UNESCO definition of which:
The state of being whole, uncorrupted and free of unauthorized and undocumented changes.
Integrity is massively important these days. It gives us the guarantees we need that digital objects we work with aren’t harboring their own sinister secrets in the form of malware and other potentially damaging payloads.
These values are contingent on bit-level preservation, the field of digital preservation largely assumes this; that we will be able to look after our content without losing information. As feasible as this may be these days, what happens if we lose some information? Where does authenticity come into play?
Through corrupting Y2K, I took time to reflect on integrity versus authenticity, as well as create some interesting glitched outputs. I also uncovered what may be the first audio that reveals what the Millennium Bug itself may have sounded like! Keen to hear it? Read on to find out more.

Big heavy box from Japan arrived yesterday. I wanted to pick up a couple of #AC3 #laserdisc & some odd films for fun. #ld

Watching #starwarsphantommenace on #laserdisc. The #ac3 #thx is awesome! The rest of the film, not so much, lol.

Assassin's Creed 3 continues to be an uncharitable game with enemy placement and optional goals. I've gotten frustrated several times with the situations it forces on me. However, I overcame most with a few desyncs per encounter.
I don't understand why they made it so enemies could chain attacks that need to be blocked! Paired with swarms of enemies it makes for an annoying, time-wasting melee encounter. Some of the tools I unlocked helped mitigate this annoyance, at least.

KTOWN: live ISO with Plasma6 Alpha. Also, chromium now supports HEVC/AC3 playback
I have uploaded a 5 GB ISO file containing a new KTOWN variant of Slackware Live. This is the KDE Plasma6 Alpha release. Play around with it and perhaps you will be able to contribute to an improved Beta by finding a
