Muchos libros de texto en epub son bastante pesados, lo que hace imposible enviarlos al kindle desde el email por superar los 50MB.
He encontrado un script de bash que permite una compresión rápida y bastante aceptable. En mi caso ha funcionado perfectamente con calidad y redimensionado del 60%, tal y como se ve en la imagen. Ha pasado un epub de un libro de más de mil páginas con más de 200 imágenes de 74 a 37MB.

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.

This is Internet Gold.
> "... 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."

New blog post where I explain how to minify your Godot export size, turning it from the default 93MB to a tiny 6.4MB file.
Some sacrifices were made, but this should serve as a guide on which options you can tune and how effective each one is!

BOOK LAUNCH — How to make books more sustainable?
→ How to make books more sustainable? Inspired by the image compression on its solar-powered website, Low-tech Magazine squeezed the article catalog of their three-volume book series into just one book. Compressing the content — an editorial and design choice — produces a larger reduction in resource use than printing on recycled paper could ever do.
→ During this book launch event, we present our "Compressed Book Edition", followed by a public discussion on sustainability in the book publishing business. We also have a number of copies for sale during the event.

Have you ever thought about how amazing modern #video #compression is?
When #QuickTime came out in 1991, the video codecs didn't save you much space, and were very primitive. You could see the (temporally) repeating blocks very obviously, and they didn't have a lot of finesse.
Cinepak was the first one that had some real compression muscle, then Intel Indeo and others.
I've got a 113-second, 720x1600 video that SHOULD take up 21GB of data raw, but easily compresses down to 16MB, and I can hardly tell the difference.
That's 1360:1 savings!

BZip3
在 Hacker News 上看到 BZip3 的連結：「Bzip3: A spiritual successor to BZip2 (github.com/kspalaiologos)」。
雖然名字看起來與 bzip2 有關，但看起來是不同的人弄出來的東西，不過有些經典的演算法有留下來用，像是 Burrows-Wheeler transform。
另外值得一提的是，bzip2 是 1996 年出的 (不過 1.0 大約是 2000 年時出的)，BZip3 的第一個 release 在 2022 年，這段時間也累積了不少有趣的演算法可以用。
無損壓縮中如果期望有比較的壓縮率，目前比較常用的應該是 LZMA 類的演算法 (差不多是 2001 年出現的)，用的工具通常會是 X
Does anyone know the compression algorithm that was used in Connectix RAM Doubler which was available for Classic MacOS in the 1990s – or, this would be even better, was the software ever reverse engineered or open sourced?
Since Mavericks (10.9), modern Mach-based OS X/macOS uses the WKdm algorithm for memory compression, so it would be interesting to see if this was already used back then.
”LLM’s are storages of millions of vector programs, that are formed by passive exposure to human output.”
No. There are so many things wrong in this!
-Not programs because they don’t execute anything
-If you give an #LLM a mathematically recursive task, it inferences in exact same time regardless of complexity
-It’s more like #compression than programs, really
-And ”passive exposure”??!! Wtf are these people smoking?!!

Alors là, je n'avais jamais vu une telle différence entre 7zip et zpaq :
Titanfall 2 : 63,7 Go.
En 7z : 39,4 Go
En zpaq (m4) : 24,8 Go.
14,6 Go de différence !
