Correct. I've read the original post years ago, I do find it it fascinating, and I would like every new generation to read it. I don't have a quarrel with it making HN front page every now and then.

Obviously we need to add the date the coordinates were encoded. The decoding will have to apply correction based on ample databases of tectonic data. A simple formula will not work, a major earthquake can move a rift by some 5-10 cm. And yo

This is basically a hash collision, two keys hash to the same digest. You'd need to add refcount to keep track, same as bloom counting filters [ https://en.wikipedia.org/wiki/Bloom_filter#Counting_filters ]

The paper also cites the main advantage of cockoo filters over bloom: ability to remove a key. (Vanilla) bloom require a rebuild of the entire filter if a key is removed from the set. There are more details in the paper, seems a good read

Bloom filters are [one of?] the most used 'negative cache' structures. Consulting a bloom filter can give a decisive answer that a key is not in a collection (ie. a key was never hashed). You can then avoid a (supposedly more ex

How long until we see the go equivalent of pinvoke.net ? http://www.pinvoke.net/ Ideally this sort of platform import should be automated so that Win32 specific apps could import the more advanced GUI stuff (comdlg et all).
