Saving the Planet, one Brotdose at a time

We Germans are known for our love of renewable energy, energy saving lamps, and recycling. I am allowed to say that, as I am one of “them” :) Our office in Berlin had another idea to reduce waste: Lunch boxes (“Brotdose” being one possible translation of that).

Most of us like to leave the office for lunch break. Once in a while we also pick up food from nearby stores, to eat it in our kitchen in the office. That means you will get a doggy bag to transport your food, mostly a box box made of styrofoam, or plastic. “ewwwww”

A Data Science Workflow for Developers

Our team was challenged with a project that involved performing actions based on plain-text requests. Having little experience in Data Science, Machine Learning (ML) and Natural Language Processing (NLP), our initial approach amounted to nothing more than “AI based on if-else statements”.

To improve our approach, we invited our Data Science team from London to visit us in Berlin. We learned about some services available to us, best practices and the like, but the biggest takeaway was nailing down a methodological workflow, which has become our go-to approach to tackle any data problem.

Read on to learn our Data Science workflow, with a practical example, and see how it can help you in your projects.

Locality-sensitive Hashing in Elixir

My team and I have built a solution that mines a stream of online articles for real-time insights for our customers. This component’s logic could be dramatically simplified if we could assume that it never receives near-duplicates of articles. While deduplication of identical documents is simple, detection of near-duplicates (i.e. “same thing, just slightly different”) is a complex but well-researched problem space.

To solve our problem, we ended up building a locality-sensitive hashing library for Elixir. Read on to find out why and how we built and open-sourced ExLSH.

Monitoring your System’s Heartbeat using Cloudwatch

Have you implemented a system that is supposed to perform tasks at regular intervals? Does the repeated failure of such a system pose a threat to your quality of service? If so, I am sure you would want to be alerted, if your system suddenly stops performing these tasks.

We at Meltwater’s Premium Content team had this exact requirement. In this post we will share how we used Cloudwatch, to monitor the heartbeat of our system.
