Creating 3D models from raster or vector data has never been that easy! This tutorial takes you through the whole process from vector/raster data to 3D in just 3 steps.
Setting up proper port forwarding for SSH connections, servers or just test purposes is crucial but isn't as straight forward as your connection should be. This post aims to be a quick guide for different use cases.
Python and pandas are a great team for data science. But what if you need to deliver a script to a Windows client who does not have Python installed?
This is a quick tutorial for converting Python scripts (

Get a 20Mb exe file that is fully functional on every Windows machine!
Have you ever wondered how HyperLogLog works? Or have you never heard of it at all? In this post I explain the wonderful algorithm of Flajolet et al. from scratch and in a very simple manner.
Flat hunting can be a big pain - particularly for European metropoles. Most flat search platforms already offer good filter options but until now, I didn't see any with custom geographic filters. Apart from drawing your own area of interest on a map, you seldomly find filters such as “How far is the next metro stop?” or “How close are important facilities?".
Leaflet-Hexbins is a powerful tool to aggregate data and visualize it quickly on a map. It can size the hexbin radius based on a feature values. But what if we used HyperLogLog data to preserve user-privacy? This post will provide a convenient way to quickly perform on-the-fly HyperLogLog unions for leaflet-hexbins.
No more backend-constraint for HyperLogLog
There are many HyperLogLog implementations out there but few work as well as postgres-hll and js-hll. They can even talk to each other by exchanging hexstrings! Usually postgres-hll is pretty much the standard extension to use, when dealing with HyperLogLog but is obviously bound to a postgres database running somewhere. With js-hll, the backend-constraint for HyperLogLog is gone, just so that users can perform any HyperLogLog action in their frontend!
