A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Avoid politics
- NEW RULE as of 5 Nov 2024, trying it out
- Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
- Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct-----

AKA “Why zip doesn’t compress things much any more”.
I see images, audio, or video files distributed in zips far too often. You're getting maybe a percent of compression if you're lucky; just distribute the raw files or use a non-compressed bundle format like tar.
But then,
tar -xzvf filename
With a bad pretend accent:
Xtract
Zee
Vucking
File
The cheeky option:
Or is it
tar --help? Oh no...tar -cf stop-nuke.tar
?
Zipping a file repeatedly typically doesn’t reduce the size further after the first time.
Yeah duoy you [realistically] can't compress compressed data...
Not sure what the original point was but curiously I happened to use
fileon a an Apple.numbersfile recently and found that it was a.zipfile in disguise with zero compression.So maybe the point was that it’s used often as a container format more often than it’s used for compression? Just my (unrelated) general computer work would also suggest this.
My 1.5gb log folders disagrees. But I never tried opening a .txt in 7-zip.
