Some questions:

* Who submitted this to scribd?

* Do they own the copyright?

* Do they have the right to submit it to scribd?

* Have they acted ethically?

* Have they acted legally?

Added in edit: These are, to me, legitimate and serious questions. Some time ago I posted a link here on HN to a PDF and it got automatically slurped to scribd. I didn't submit it to scribd, I don't hold the copyright, and now I find that the traffic that might have gone to the original site has been usurped by scribd.

I find that distasteful.

Pragmatically, anything you post to the web is now fair game for being duplicated elsewhere, your work being taken, possibly having ads put all over it, and generally ripped off. That's just the way it is, I know, but I find it odd that a company that seems purely to make money by ripping off other people's work is supported by HN.

But that's all I'll say. Most likely I'm in a minority in wondering about the ethics.

The first hit on Google is a link to the paper on the lead author's website, so I think your issues are non-issues.

IIRC, scribd claims the right to (re)publish uploaded material, and will automatically put submitted material behind a paywall. It's also theoretically possible for the submitted material to rank above the author's home page, which is not necessarily desirable (if only because updates won't be available).

In short, this is not as innocuous as you think.

The Google-juice argument is slightly convincing, but any right to republish the document remains with the original copyright holders, no matter what Scribd claims. (Consider YouTube in a similar position.)

Consider e.g. the people holding copyright on popular movies uploaded to YouTube. Their rights are still protected, but filing all those takedown requests is a major pain.

(Which is not to say that I agree with all of their attempts at "fixing" this.)

This is why we can't have nice things.

I'm not sure how this falls ethically, but since there's no working copy online (via author, nyud.net, or scribd) and the author does give it away for free, here's a working dropbox link courtesy of Neillithan on Reddit:

http://dl.dropbox.com/u/1997866/_Public%20Documents/Depixeli...

It's overloaded, try another mirror. Megaupload, mediafire, etc that is designed to share docs

It seems like the scribd-mirror has been removed. The original was posted here, but the server is not responding: http://johanneskopf.de/publications/pixelart/paper/pixel.pdf

mirrored at http://dl.dropbox.com/u/49901/mirror/pixel.pdf

Please someone implement this as a filter for ScummVM.

Given the results with the Mario game cast members on the final page, this would be an excellent filter to apply (in realtime) to an old Mario game.

Yes they've done that. See the video linked from the original post:

You can't because the page is cold dead.

Check the link I posted, scroll down to the video.

The download starts downloading for me after a few minutes. If it doesn't you could click the comment below it to download from another location.

It's been deleted?

So which SNES emulator does this?

Pretty impressive, but it looks like there's still a bit more improvement possible.
