I feel guilty for taking up >14 MB on that last toot, but the downscaler on my phone didn't seem to have a batch mode. :(

But then again, I think Ad?min is def' gonna be ok with this one ;)

@rl_dane

It's a worthy cause. :)

Also GoToSocial automatically does compression and what not.

@amin

That was the size downloaded (looking at /tmp/tutfile1111111yaddayadda.jpg)

Random aside, why the heck are people still enforcing three-letter extensions? That's so dumb. :P

@ddlyh @rl_dane

Speaking of, the "P" should pronounced as an "F". After all, it stands for "Photographic".

I will die on this hill.

@ddlyh @amin

JFIF is the container format. JPEG is the spec/algorithm.

...as I understand it...

@rl_dane @ddlyh

Strictly speaking, "JPEG" is the name of the group that made the spec. "Joint Photographic Experts Group". ;)

@mirabilos @amin @ddlyh

I'm not a fan of providing retronyms for abbreviations necessitated by crappy operating systems and/or crappy conventions.

It should always be .jpeg, in my book.

@ddlyh @amin @rl_dane nah, 3-char extensions are fine and the usus.

And in some cases even more correct, e.g. in .htm (as the file is not the language).

@mirabilos @ddlyh @rl_dane

And if we’re talking the Unix world the file extensions are basically ignored anyway. It’s only on Windows that it actually matters.

@amin @mirabilos @ddlyh

Ehh, kinda.

Graphical file managers (Yes, I know the REALLY cool kids don't use 'em) use the extension to determine the mime type.

The craziest was classic Macintosh OS, which did not use extensions at all (and most applications (especially in the early days) did not create them). File type was determined by an invisible (kept in the fs metadata) case-sensitive four-character alphanumeric file type code, and file association was determined per file via a similar four-character creator code.

So a PNG you created in Photoshop would always open in Photoshop, and a PNG you opened in Illustrator would always open in Illustrator. And a file named "Mona Lisa" was just "Mona Lisa," not "Mona Lisa.JPG" or "mona_lisa.jpeg." Later Macintosh applications started adding extensions to standard files (like JPEGs) to ease compatibility with PCs, but most native Macintosh applications had no three-letter extension set or defined in any way.

Somehow, we never thought all that that odd in the least.

Modern MacOS is even weirder, using neither extension, MIME, nor type codes, but something else I don't know the name of (but it's strongly tied to extension and MIME type)
