File formats as Emoji: 0xffae

by @beet_keeper

tldr: https://emoji.exponentialdecay.co.uk

File Formats As Emoji (0xFFAE or 0xffae) might be my most random file format hack yet. Indeed, it is a random page generator! But it generates random pages of file formats represented as Emoji.

The idea came in 2016 with radare releasing a new version that supported an emoji hexdump. I wondered whether I could do something fun combining file formats and the radare output to create a web-page.

Along came a spare moment one weekend, some pyscript, and bit of sqlite, et voilà. File Formats as Emoji (0xFFAE) was made a reality.

A screenshot of a file format (fmt/983) in 0xffae. The title 0xffae sits over the top of the original image.

An image of the skeleton suite in Linux. The file extensions trigger display of the correct application icon for each of the files and so it looks like you have a lot of different file types around.

@wyatt @kawa Until archive format overhead becomes the limiting factor for size.

At one point in early 2002, I briefly considered using the UNIX tape archive (tar) format to bundle assets in a Game Boy Advance game. Many of these assets were 2048 bytes or smaller. I looked up the spec for a POSIX tar file, and it involved rounding up each file's size to a multiple of the 512-byte block size and adding a 512-byte block header. That kind of overhead adds up. On top of that, searching for a particular file in a tarball takes linear time, not constant or even logarithmic time.

That led me to devise and document a simpler, more fit for purpose archive format called GBFS. Other specialized archive formats may benefit from packing files so as to avoid crossing 16K, 32K, 64K, or 128K block boundaries in the medium.

I'd like to take a moment to speak to you about the Adobe PSD format

Huh.

Right this second is when I learned that the .mobi file format is owned by Amazon !

Hmmm, advice please.

So; say you're a #opensource #vector image editor and a volunteer pops in to help write a new compatibility to some proprietary #fileformat.

Say the volunteer makes progress and one day a brand new account claiming to be the founder at the #proprietary company of said format offering the volunteer a job.

To me; this is clearly a way to foreclose work on compatibility. The #foss equiv of buying out a competitor.

But how should the project moderate this kind of message?

A year in file formats 2024

by @beet_keeper

A great write up from Francesca at TNA about the past year for PRONOM via Georgia at the OPF.

It’s great to see the continuing work including vital translation of guides into other languages. Francesca includes a couple of shout outs to some pieces I have contributed in my spare time this year; including a collaborative workshop with Francesca, David, and Tyler at iPRES2024.
