How to handle big data on modern computers. See the slides of my recent talk at Curtin University: https://t.co/jnNElhITfU
Look specially at how compression can help in satellite imaging at NCI.
Nowadays computers are being designed quite differently as they were made more than a decade ago; however, very little in software architecture has changed in order to accommodate for the changes in the hardware architecture. During my talk I am going to describe which those fundamental changes are and how to deal with them from the point of view of a long-time developer.

As times goes by the CPUs are more starved than ever before.  And compression (more in particular: Blosc) can help in this fight. Updated benchmarks for Intel Skylake: https://github.com/Blosc/movielens-bench/blob/master/querying-ep14.ipynb

PyTables is adopting a new interface for allowing different backends, and most specially h5py: https://github.com/PyTables/PyTables/blob/pt4/doc/New-Backend-Interface.rst
The work has started, but this project still needs some more love.

Some updated benchmarks on what you can expect from some of the different codecs that come with Blosc: http://python-blosc.blosc.org/tutorial.html#compressing-and-decompressing-with-blosc

Our call for opinions on how to fund the PyTables project is finally making some users (and possible funders) to respond: https://groups.google.com/forum/#!topic/pytables-users/yY2aUa4H7W4
Would you like to share something too?
Although Antonio Valentino and Anthony Scopatz have been doing a terrific work maintaining the library, it seems like nowadays they are too busy to continue putting time in PyTables anymore. We know that there are many projects out there using the library, and we are in a point now where we ...
