8 minutes to compress 1 image? WTF man, that's ridiculous. You get light from the sun in that time.

compression:
I suspect a similar thing could be done with gzip compression dictionaries - running through the file to be compressed a very large number of times (beyond gzip -9) to select the best dictionary before a final best-compression encoding.

Burn CPU to save disk space and transmission time on stuff to be delivered a lot.

I wonder also if this jpeg compression approach can be factored into MPEG delta compression for movies... again, burn CPU upfront for a better, smaller delivery.

This is a bad day for Grubes. Breakthrough tech from Google - and open source! - and gorgeous new phones from Samsung.

And what news from Apple? Oh, different iPads?

Oh.

on compression:
the problem with gzip is that it's stream-based and single-pass with a limited window, so that it can fit into the unix piping streaming thing. reworking it to go through multiple times would be a lot of effort.

gzip?

what's wrong with binhex?

@Dumb Grub

It really is unusably slow, though.

I built it the other day (which was a PITA because they use a screwy build system) and waited 20 minutes for it to process a single image from my SLR.

OK, just pulled the latest tree from github and they fixed the build system, at least.

Still runs slower than natural evolution, though.

Wake up Grubs! There are new iPads to jerk off upon!

Also here's Siri doing something stupid: http://deadspin.com/siri-unaware-women-play-four-quarters-of-basketball-c-1793468986

It's a good tradeoff for people that are serving media. A 10% space savings becomes a huge bandwidth saver.

Still, it'll make updating graphics on a website an exercise in patience, something most web people don't have a lot of.

"Photoshop is still saving the image! WTF!"

It’s not going to be a tradeoff that suits everyone: 10% bandwith savings vs 10x (being generous, it’s more like 400x) increase in encoding time means real-time transcoding is impossible, for example.

Lets see how long he waits to post about the new Apple "releases".

Is the encoding SSE-aware? Or is that speed already SSE-aware? That'd be brutal.

It's almost like you need a web crawler that goes around in its spare time and compresses images for you.

Dammit Biff! Even Gruber understands that this is not suitable for real-time work. Guess what? You don't have to sit there and wait for it to finish! Go visit pornhub while you're waiting!

FTFY.
