Show HN: InBloom – Portable Bloom Filters in Java, Python and Go (github.com)

Thanks! We figure, if we write infrastructure stuff that is not part of our core IP, we might as well open it so it won't rot, or at least rot much slower - and you might even get improvements to what you do.

Even if it's not a big project like redash, it still helps if you get occasional bug reports and pull requests. Another added bonus - people tend to write higher quality code if they know it's going to be open.

Here are a few of our other projects besides redash and Inbloom:

Magneto - Android test automation https://github.com/EverythingMe/magneto

Jitt - Just In Time translations for Android apps https://github.com/EverythingMe/jitt

GoFigure - easy configuration file parsing for go https://github.com/EverythingMe/gofigure

Plaxien - nice "explain" interface for in-app reporting in Android https://github.com/EverythingMe/plaxien

Geodis - a redis based geo-resolving and geo search library in Python https://github.com/EverythingMe/geodis

Rainbow - AWS Cloudformation on steroids https://github.com/EverythingMe/rainbow

OpenSpace - a nice dashboard to showcase our open source projects. https://github.com/EverythingMe/openspace (the full list of projects is demoed on it here - http://everythingme.github.io/)

Thanks :)

HLL can only estimate cardinality, it can't test for the existence of a key. The idea is the same - sacrifice some precision and gain a huge memory saving. But they don't share anything beyond that in terms of the math.
