if you could pick a standard format for a purpose what would it be and why?
e.g. flac for lossless audio because…
(yes you can add new categories)
summary:
- photos .jxl
- open domain image data .exr
- videos .av1
- lossless audio .flac
- lossy audio .opus
- subtitles srt/ass
- fonts .otf
- container mkv (doesnt contain .jxl)
- plain text utf-8 (many also say markup but disagree on the implementation)
- documents .odt
- archive files (this one is causing a bloodbath so i picked randomly) .tar.zst
- configuration files toml
- typesetting typst
- interchange format .ora
- models .gltf / .glb
- daw session files .dawproject
- otdr measurement results .xml
Ogg Opus for all lossy audio compression (mp3 needs to die)
7z or tar.zst for general purpose compression (zip and rar need to die)
The existence of zip, and especially rar files, actually hurts me. It’s slow, it’s insecure, and the compression is from the jurassic era. We can do better
@dinckelman @Supermariofan67 I think you mean unsecure. It doesn’t feel unsure of itself. 😁

@hungprocess touché.
One thing I didn’t appreciate about English until reading a Europe forum for a while is that it has a lot of different prefixes that mean something like “not”, and this is not very intuitive to people learning the language. Their use is not regular.
Consider:
“a-” as in “atypical”
“non-” as in “nonconsentual”
“un-” as in “uncooperative”
“im-” as in “immortal”
“in-” as in “inconsiderate”
“il-” as in “illegitimate”
“mal-” as in “maladjusted”
“anti-” as in “anti-establishment”
“de-” as in “deconstruct”
And sometimes, some of the prefixes are associated with base words to form real words with similar meanings, but meanings that are not the same. For example, “immoral” and “amoral” do not mean the same thing, though they have related meanings.
@hungprocess Also this. https://english.stackexchange.com/questions/19653/insecure-or-unsecure-when-dealing-with-security
It seems that I was quite wrong, but that a lot of other people are wrong as well. lol
why does zip and rar need to die
Zip has terrible compression ratio compared to modern formats, it’s also a mess of different partially incompatible implementations by different software, and also doesn’t enforce utf8 or any standard for that matter for filenames, leading to garbled names when extracting old files. Its encryption is vulnerable to a known-plaintext attack and its key-derivation function is very easy to brute force.
Rar is proprietary. That alone is reason enough not to use it. It’s also very slow.
Again, I’m not the original poster. But zip isn’t as dense as 7zip, and I honestly haven’t seen rar are used much.
Also, if I remember correctly, the audio codecs and compression types. The other poster listed are open source. But I could be mistaken. I know at least 7zip is and I believe opus or something like that is too
Most mods on Nexus are in rar or zip. Also most game cracks; or as iso, which is even worse.
I have seen RAR on Nexus, but I wouldn’t say that it’s common, at least for Bethesda’s games, which is where I’ve seen it.
Things may have changed, but I recall that yenc (for ASCII encoding), RAR (for compression and segmenting) and PAR2 (for redundancy) were something of a standard for binary distribution on Usenet, and that’s probably the main place I’ve seen RAR. I think that the main selling point there was that it was just a format that was widely-available that supported segmented files.
That would explain why I don’t see them often. I haven’t been very active in gaming as of late, let alone modding. And I generally don’t pirate games. I’m cool with people that do, I just don’t personally. (Virus fears, being out of the loop long enough that I don’t know any good sites, etc)
Honestly, if desktop operating systems supported better sandboxing of malware, I bet that piracy would increase.
why does ml3 need todie
It’s a 30 year old format, and large amounts of research and innovation in lossy audio compression have occurred since then. Opus can achieve better quality in like 40% the bitrate. Also, the format is, much like zip, a mess of partially broken implementations in the early days (although now everyone uses LAME so not as big of a deal). Its container/stream format is very messy too. Also no native tag format so it needs ID3 tags which don’t enforce any standardized text encoding.
Not the original poster, but there are newer audio codecs that are more efficient at storing data than mp3, I believe. And there’s also lossless standards, compared to mp3’s lossy compression.
How about tar.gz? How does gzip compare to zstd?
Both slower and worse at compression at all its levels.
its worth noting that aac is actually pretty good in a lot of cases too
However, it is very patent encumbered and therefore wouldn’t make for a good standard.
aac lc and he-aac are both free now hev2 and xhe aren’t, but those have more limited use
How about xz compared to zstd?
At both algorithms’ highest levels, xz seems to be on average a few percent better at compression ratio, but zstd is a bit faster at compression and much much faster at decompression. So if your goal is to compress as much as possible without regard to speed at all,
xz -9is better, but if you want compression that is almost as good but faster,zstd --long -19is the way to goAt the lower compression presets, zstd is both faster and compresses better
What’s wrong with mp3
Big file size for rather bad audio quality.

Oh, a gramophone user.
Joke aside, i find ogg Opus often sounding better than the original. Probably something with it’s psychoacoustic optimizations.
