MongoDB and geodata part 1 – from Shapefile to MongoDB 3.2

MongoDB (3.2) is a kind of database-hipster at the moment – with improving support for spatial data. So it was time for me to discover some of it’s features concerning spatial data. As a GIS-user my first intention was to get some bigger simple (point) geodata into MongoDB. Part 1 covers this topic, part 2 will cover some spatial operations within MongoDB. I also want to do some performance checks between PostgreSQL/PostGIS and MongoDB related to geodata.

YouTube Audio Player


For one year I have tried to create my own YouTube Audio Player. I wanted something that can play my playlists and favorite music from YouTube, but I only wanted the sound – no video. In that case I usually used a separate browser-window or -tab and that was sometimes very annoying.

Download all OS

So this player is build on top of NodeJS and Electron and uses the Google API for all YouTube requests. The code and the structure is available on GitHub.

Raspberry Router


I built myself a UMTS router. An extravagant one. Out of scotch tape and parts I found in my apartment. Here’s how.

First of all: This is not your usual router. This thing was initially built out of necessity: I had (and still have) an unlimited/uncapped mobile data plan for my tablet, which is not capable of doing wifi tethering for my phone. So as a student (read: lazy and cheap) I did not want to leave the four walls I call home dormitory just to watch Youtube videos on my phone.
