August 31st - Instalment #33

Week No.33, and as we come to the end of the summer season with people returning back from holiday, it is good to see that there has been no slow down in open source activities. This week we have plenty of blog posts, projects for you to check out and customer stories.

We also have a growing list of events to add to your diary, so make sure you check these out too. Again, if you have any open source events you want me to share on this newsletter, then please let me know.

Something to read

First up is a blog post from Daniele Scasciafratte announcing An Open-Source Book About the Open Source World, which I am currently working through (the pdf version) and is a kind of hybrid book in such that it reads like an autobiography about Daniele's open source journey. Along the way he shares what he has learnt, and it kind of works as it makes it easier to read than many of the books on this subject. You can start reading via this link here. Nice work Daniele!

Your feedback matters!

I have put together a short feedback survey, which I would ask you to take - it will take no more than 2 minutes. You can access here. Many thanks!

Take the survey

Case Study

TalkingData and Deep Java Library - DJL

How TalkingData uses AWS open source Deep Java Library with Apache Spark for machine learning inference at scale this post via Xiaoyan Zhang, a Data Scientist at TalkingData, looks at how you can use this open source project to simplify and reduce cost when approaching machine learning. TalkingData is a data intelligence service provider that offers data products and services to provide businesses insights on consumer behaviour, preferences, and trends. Deep Java Library (DJL) is a Deep Learning Framework written in Java, supporting both training and inference. DJL is built on top of modern Deep Learning engines (TenserFlow, PyTorch, MXNet, etc.). This post walks you through a machine learning model that TalkingData used to showcase their solution of using DJL to run inference for PyTorch models on Apache Spark, and shows how this approach provided an end-to-end solution to run everything on Apache Spark without involving additional services, and reducing running time by 66% and reduced maintenance costs.
