enz / unz

UPDATE: added support for zip-compatible symlinks. enz works exactly like zip by default storing linked files, using the -y switch to store links only.

github.com/ha1tch/unz

enz and unz are a zip-compatible compressor and decompressor pair that beat zip -9 on source code by 5-10%. Uses smarter pre-processing before DEFLATE.

It's often better than the alternatives for text, source code, structured text files, and markup.

Pure Go. No dependencies beyond stdlib. Output works with standard ZIP tools where possible

Benchmarks available.

SSDs, but specially RAM prices are skyrocketing: arstechnica.com/gadgets/2025/1

These are excellent times for using compression to reduce your storage pressure.

For text with a lot of repetition, #bzip3 still blows my mind. 😆

rld@Intrepid:Documents$ for x in cat "gzip -9" "zstd --ultra -22" "xz -9e" "bzip2 -9" bzip3; do $x < weatherlog-2024.txt |wc -c |tr "\n" "\t"; echo "$x"; done
 1735300	cat
   80423	gzip -9
   63275	zstd --ultra -22
   53516	xz -9e
   52374	bzip2 -9
   40645	bzip3

ZSTD with level MEDIUM gives you the same runtime as the traditional MS_XPRESS algorithm, but the backup is around 14 GB smaller. The level LOW is really fast (203 sec. vs. 305 sec., and the backups are still smaller (58 GB vs. 50 GB). #sqlserver #zstd #compression #performance

Gibt es hier Menschen (insbesondere mit Testosteron-motiviertem Beinhaarwuchs¹), die Kompressionsstrümpfe/strumpfhosen tragen und Tipps für mehr Tragekomfort / weniger Jucken haben?
Meine nach Maß gefertigte Klasse 2 Strumpfhose (auch schon mit Baumwolle auf der Innenseite) piekst und juckt direkt nachm Anziehen schon, vorallem am Oberschenkel. Es wird dann nach kurzer Zeit ein bisschen besser, aber immer noch störend und so, dass ich die wenn dann nur für ein paar Stunden an habe und danach sehr froh bin, die auszuziehen.

Ich hab mir auch noch kniehohe Strümpfe in passender Standardgröße gekauft (mit Bambus und Wolle Anteil). Die sind deutlich besser, ab und an jucken die auch, aber ich kann die ohne Probleme den ganzen Tag tragen. Aber die haben halt auch weniger Wirkung.

Abends Beine eincremen hab ich schon ausprobiert, das ändert gefühlt gar nichts am Tragekomfort am nächsten Tag.

Beinhaare etwas kürzen hat ein bisschen geholfen, aber auch nicht viel.

Hat noch jemand Tipps?

Gerne boosten

¹Ich hatte mich zu dem Thema bisher nur mit zwei Frauen unterhalten, die damit beide nicht wirklich Probleme hatten, daher die Frage vor allem auch nach Erfahrungen von Männern, freue mich aber über Tipps von allen.
