Visualization of noise pollution for the entire world based on top of OSM data. Search for your city and check for the noisy places. Using global street, landuse and building data from OpenStreetMap we can approximate where noise pollution might happen. We use a very simple noise model inspired by noise pollution concept of Cities Skylines.
If you are working on a web map it is difficult to see what changes a line of CartoCSS can cause. With visual regression testing you can create a diff between versions and ensure quality.
Building realtime apps on top of GitHub is kind of a pain because GitHub only provides a plain HTTP API to it’s public events. This is why I built the GitHub Realtime Relay (GHRR) which polls all public events and then relays them directly via websockets. This is probably the simplest way to create a realtime application on top of GitHub.
OpenStreetMap now provides public access to the access logs of their tile map server from 2014 until today. In this article I will show you how to parse the access logs with Bash and Python and visualize the data with CartoDB.
I analyzed 370 million files of 614k Github repos to find out which Continous Integration services developers use. I looked at public Github repos that were recorded in the GHTorrent dataset of 2015-01-29 and are not forks of other projects. The dataset is available at the repostruct Github Repository.
In 2011 the Chaos Computer Club revealed a major complexity attack vulnerability that works across all major languages. PHP addressed the vulnerability for forms but never really fixed it. Nowadays every web application uses a JSON API, which is still vulnerable to complexity attacks.
I will compare and review the different APIs of end user cloud storage providers. I will only look at the HTTP API aspect, not how this API is implemented for various languages. The motiviation behind this is research for my common cloud storage API.
