Last RISC OS icon I created (I think ..)
This is for ungzip, which does just that. Gavin Wraith's drag-and-drop WIMP wrapper (stick) that runs a trivial perl script that calls the gzip binary.
This lets me uncompress gzip files from the GUI.
Stick does the magic of making drag-and-drop happen. The perl script converts a RISC OS filename (foo.bar/gz) into a unix style path (foo/bar.gz) and feeds the path to gzip.

[Перевод] Уменьшаем базу данных в 2000 раз при помощи Rust (завершение)
Сериализация По сути, мы получили косвенную базу данных в памяти. Далее нам нужно сериализовать её, чтобы проверить, как interning влияет на её постоянное хранение. Кроме того, сериализация — это важный шаг для проверки реальности заявленной экономии места. И, наконец, это ещё одна возможность для дальнейшего сжатия данных. В Rust для сериализации стандартно используется крейт serde , который мы уже использовали для импортирования входных данных в JSON. Serde изначально имеет поддержку множества форматов благодаря крейтам расширений, поэтому я решил попробовать несколько из них.

GNU #gzip víc než 1 CPU nepodporuje, ale #pigz ano, který jsem použil pro porovnání rychlosti.
What is a #tar file?
https://depot.dev/blog/what-is-a-tar-file
« What the heck is a tar file? Since the 1980s, tar has been the go-to method for bundling and archiving multiple files, simplifying the transfer and storage of file collections on magnetic tape.
But, what exactly is a tar file, and how did a magnetic tape utility become the standard for archiving files even 40 years later? »
A fun and interesting look into the tar—and #gzip of course—file formats.
OMG I haven't had to look up tar/gzip stuff in years :)

Very much liking the succinctness of the JS Compression Streams API[1] and wish I'd known about this a couple of years earlier. Here're some small helpers to compress or decompress a byte array...
I've just also pushed a new version of https://thi.ng/genart-api (v0.11.0) in which the reference implementation platform adapter now uses gzip compression for serializing the data of image maps/parameters (in ~50-60% of the original size)...

(edit: removed obsolete `async`)
![TypeScript source code:
```
const compressBytes = (
buf: TypedArray,
fmt: CompressionFormat = "gzip"
) => pipe(buf, new CompressionStream(fmt));
const decompressBytes = (
buf: Uint8Array,
fmt: CompressionFormat = "gzip"
) => pipe(buf, new DecompressionStream(fmt));
// shared compression/decompression helper
const pipe = async (
buf: TypedArray,
stream: ReadableWritablePair<any, Uint8Array>
) =>
new Uint8Array(
await new Response(
new Blob([buf]).stream().pipeThrough(stream)
).arrayBuffer()

I'm no software developer, and my code isn't afraid to tell me so.
I've been working on a thing that ciphers, compresses, and encodes text to create stupidly long URLs. This was the output of one of my tests. The code doesn't lie.
