The Julia language reached the important milestone of a 1.0 release on Wednesday (August 8th). During a party in the rather swish Institute for Engineering and Technology overlooking the Thames in London, the founders of the Julia language performed a live push of the 1.0 version to Gitbub.

The significance is that the Julia language has often been criticized for changing the language in ways which break old code at minor version number changes. The recent 0.7 version was intended as a preview of 1.0, i.e. there would be no breaking changes between 0.7 and 1.0. Version 0.7 lasted around a month, and there was a lot of traffic on the Julia discussion board on how packages are being slowly updated to 0.7 compatibility. Now with version 1.0 we can look forward to a stable language - so if you have not looked at Julia yet this is the ideal time to try it.

The first day of JuliaCon 2018 consisted of a series of in-depth tutorials. The conference proper launches tomorrow. The venue is at the Roberts Building in UCL. As London is still baking in a heatwave I am rather glad that the lecture theatres are well air conditioned! AV facilities are rather good also. More highlights follow.

From the "How to be a Hadoop/Spark smarty pants" department

Say it with me, "Apache Hadoop® is platform for data lake computing." There is a lot to unpack in that sentence. Specifically, Hadoop used to be a monolithic MapReduce engine. Now it is starting point for many other types of data analytics projects. Spark is a very popular and powerful language (written in Scala) that has an API for Python, R, and Java. Data lakes are large repositories of raw data that live in the Hadoop Distributed File System (HDFS). Then there is a resource manager called YARN (Yet Another Resource Negotiator) that supports dynamic run-time resource usage and data locality (among other things). Where to begin?

A Language Named Sue

The Johnny Cash song A Boy Named Sue tells the story of a father who knows he will not be around to bring up his son, so names him Sue to make him tough.

There is no such story regarding the naming of the Julia language. It is not an acronym, neither is it named after a famous scientist or engineer. It is just called Julia because it sounds good. But it is sure able to stand up for itself when sand gets kicked in its face.

This is my first rather short blog from the Julia Conference 2018 at University College, London. You can follow the conference on this live stream.

Sadly the Man in Black is no longer with us to sing about Sue. Or Julia.
