Programming

I mostly blog about solutions I’ve made for problems I’ve encountered during my workday. The stack we use at Wehkamp is huge, so there’s always an interesting topic to blog about and many programming challenges to deal with. My main specialty is backend (.NET Core / ASP.NET / C#), but I do my fair share of Node.js and Python.`

Amazon S3, AWS Lambda, bash, Python

AWS Lambda Size: PIL+TF+Keras+Numpy?

At Wehkamp we’ve been using machine learning for a while now. We’re training models in Databricks (Spark) and Keras. This produces a Keras file that we use to make the actual predictions. Training is one thing, but getting them to production is quite another!

The main problem we’ve faced was that it was too big to actually fit into a lambda. This blogs shows how we’ve dealt with that problem.

Fizz? Buzz? FizzBuzz? Let’s discuss.

What’s the buzz all about? Well, originally it started out as a small children’s game, but now and again I see it being used to detect weak developers in job interviews (I think there are better ways to do this). The assignment has a view nice properties. In this blog I would like to look at some implementations and discuss the pro’s and con’s of each implementation.
