Releasing bitmapist.cohort - or how we saved over $2000/month! - amix.dk
I released bit mapist a while ago and I am happy to release an extension that makes the library much more powerful! Installation and source code sudo pip install -U bit mapist Fork the code at Github. The reason why I implemented this I want to tell you why I coded this (and how we saved over $2000/month by having this library). I looked at Mixpanel's retention feature - which seems amazing.

redis-faina: a query analysis tool for Redis
As we mentioned in our previous blog, weâ€™re big fans of tools and techniques for introspecting our live traffic to see what exactly is going on. One tool we use frequently is PGFouine, a query traffic analyzer for PostgreSQL. We recently found that we also needed a similar tool for Redis, our swiss-army-knife list/set/etc storage.

Redis bitmaps - Fast, easy, realtime metrics -
At Spool, we calculate our key metrics in real time. Traditionally, metrics are performed by a batch job (running hourly, daily, etc.). Redis backed bit maps allow us to perform such calculations in realtime and are extremely space efficient. In a simulation of 128 million users, a typical metric such as â€œdaily unique usersâ€ takes less than 50 ms on a MacBook Pro and only takes 16 MB of memory. Spo

Scripting branch released
Warning: the scripting API was modified in recent versions of 'scripting' and '2.2-scripting' branch. Now Lua can call Redis commands using Redis.call('get',...) instead of Redis('get',...). Also the EVALSHA command is now available in both branches. As expected I did not resisted to the temptation of implementing a branch with Lua scripting support for Redis, and this weekend was the right moment
