I see devrant has added a feature never saw this before... It's pretty good... Can somebody tell me how it does the check ?

Probably @dfox could explain it to you

@Alice it not only checks whether I have made that post previously but also the whole devrant DB I guess, because I never made that post previously...

@irene I guess it is possible but how reliable would it be... like if I changed the image a little bit like added extra margin or a little crop maybe... I would like to test it out but I'll have to wait for another hour or so before I can make another post.

@dudeking couldn't find the repo

My guess is a bitmap hash with a lookup on a timescaled post array.

This feature exists for a reason. Don't circumvent it by cropping or some shit.

This was introduced a while ago, wasn't it?

@gdsoumya its not opensource but there is a repo

@filthyranter the feature exists and that's good but as a developer I guess I'd like to test its limits...

@sbiewald idk... There was a feature that prevented a user from reposting stuff that they had made previously but this seems to work for every post made by all users...

@Codex404 yes, I did find a devrant repo but it was just for issues and stuff.

@sbiewald
Yes. This feature is pretty old.

This feature is old by now. It's to let you know if something has already been posted recently. It works off a Hask so only exact matches are detected, which is why you haven't noticed this feature before. Because it is not very effective.

Yes it's a hashing algorithm.

@ewpratten In the sense that 0.00001 is greater than 0, yes
