Compute Bigger with Cat2Cloud Compression!

In this third video, we explore lazy expressions —a compression-native tool to optimize operations on your data using the Cat2Cloud web client.

With lazy expressions, you can decompress and compute data only when needed, saving time and resources!

Thinking about #Compression for #RetroComputing #PixelArt on monochrome (1bpp) images...

Obviously, Huffman does nothing. Obviously, RLE and LZ applied to bytes only catch repetitions if they're apart by a multiple of 8 pixels, i.e. rarely outside of large uniform areas.

But then, what works? Classic algorithms applied at the bit level? On pairs of bits?

Excited to announce the release of the second cat2cloud introductory video!
Our software optimises file transfer and access for server-hosted data . cat2cloud's compression-first framework enables users to minimise transfer times and storage requirements .

In this video, you can see how easy and quick it is to manage file storage using the ubiquitous jupyter notebook format !

I am looking for a professional #mixing #electronicmusic tutorial (#gainstaging, #eq, #compression, #stereopositioning, #delay, #reverb, #chorus, etc.).
Can anyone recommend something?
Does not need to be free. Does not have to be #bitwigstudio specific.

> "... it is important to note that the compression algorithm used by lzip only discards the unimportant data. And if it was unimportant before, what makes it so important now? Huh? In fact, many users may find that compressing their entire file system and then restoring it will be a good way to learn what is truly important."

Brand new PEP by @emmatyping to add Zstandard to the standard library:
https://peps.python.org/pep-0784/

Will it make it in to 3.14 before the feature freeze on 2025-05-06? It'll be close but it's possible!

The PEP also suggests namespacing the other compression libraries lzma, bz2 and zlib, with a 10-year deprecation for the old names.
