Creation Of A Prototype - Part 1

the carbon fibre structure, freshly stitched

low pressure, 0.5 bar

It was taken out of the tempering oven too early. The rapid temperature change destroyed the violin. at least it was a very cheap one. The structure came out fine, though.

Oil on copper it is. Could have aimed for a smaller picture because of the largish portrait. The nude in the mirror will be easier to paint this way.

gdzip released

I humbly announce the release of gdzip.
Gdzip is a command line tool to compress and encrypt files or folders. It is written in Go.

Executable binaries as well as the source code can be downloaded at Github:
Source code: https://github.com/w33zl3p00tch/gdzip
Releases: https://github.com/w33zl3p00tch/gdzip/releases

Internally, the given files and/or folders are compressed and stored as tar.gz archives that retain the original file metadata.
The data are split into chunks while encrypting, and encryption is done done using AES256-GCM and/or ChaCha20-Poly1305. All this happens in RAM, so no temporary files will be used.

Keys are generated using the scrypt key derivation function.

The encrypted files provide no information about their contents or their contents' filenames.

Encrypted files may be safely renamed and even the extension may be altered or left out.

Please report any bugs you might find. Suggestions and feature requests are welcome.
