Take Care of Hundred Containers and Not Go Crazy
Limited Capacity full

"Imagine you have four different databases, five popular languages, and six other interesting technologies, that you want to put into container image, make them nicely run in OpenShift, and support for few years. However, you soon realize that you want to support not only one version of the particular technology, and the images are not based on one distribution only. Then you easily find yourself developing and maintaining hundred of container images or more.

Something similar happened to us and I admit we did not know all the tricks from the first minute. Come and hear what issues we met during the way, so you do not repeat them as well. We will cover upstream/downstream design, de-duplication of the sources from more perspectives, automation based on Jenkins, and of course testing."

Probabilistic structures for scalable computing
Limited Capacity seats available

"In this talk you'll learn about streaming algorithms and approximate data structures to characterize data sources that are too big to keep around or difficult to replay. We'll start simple, with an algorithm for on-line mean and variance estimates of a stream of samples. Then we'll look at Bloom filters (for approximate set membership), count-min sketch (for approximate member count in a multiset), and HyperLogLog (for approximate set cardinality). We'll cover implementing these algorithms, using them for data analysis (and even machine learning), and provide some intuition for why they work at scale. Come with reading knowledge of Python and leave with some cool new options in your scalable data processing toolbox!"
