I *really* want to see #rss get into the #mainstream https://www.niemanlab.org/2022/12/this-i.. I still believe it needs to handle two problems: 1. #redistribution checking (content #hash ) and 2. #comments . #comments could be handled via #email but ideally #rss itself woudl handle this. Anyway, I still want to see #deadsocial based on #rss and completely #distributed .
Wow, somebody found a #sha 3 #hash #buffer #overflow https://mouha.be/sha-3-buffer-overflow/ Pretty impressive! Worse still, this #code has been #vulnerable for over 10 years!
Yeah you probably shouldn't be using MD5 #hashes anymore: https://github.com/corkami/collisions It seems now #trivial to #generate #collisions - very cool for #cracking old #technology . We can now make *some* SHA1 #collisions happen, I imagine in the #future we can make #hash #collisions happen trivially for something like #git or for #password checking.
Very interesting #visualization for #maze #solving https://www.jwz.org/blog/2022/08/solving.. I wonder what other #problems could be looked at in this way? What would a #hash look like when #visualized in this way?
#opensource work towards #video #hashing ( #perceptual video #hash ): https://pypi.org/project/videohash/ The idea is that you can check whether two different videos have matching #content instantly. It is still a way off and makes a bunch of #assumptions - but in theory it could lead to some interesting ideas, like the ability to #rebuild #torrents from #random #sources ...
Interesting #rolling #hash #concept for #rabinkarp #string #search https://yurichev.com/news/20210205_rolli.. Always great to see something I hadn't even ever considered before. Very cool.
#apple 's #csam is even worse than previous thought, people are finding #hash #collisions in the wild: https://blog.roboflow.com/nerualhash-col..

So essentially #stateactors have the ability to #reverseengineer their vectors.Scratch that, it looks as if people are actually generating #hash #collisions by modifying an existing image to match a #hash https://github.com/AsuharietYgvar/AppleN.. #apple have really fucked up on the response to this one... They should at the very least put #csam on ice until #researchers have been given more time to figure this out. Also, claims that it's "not the final #version " is not good enough, especially when you invited people to #attack it!
