Lakka 2.0 – Retro-Gaming

It’s has been a long time since I had time for some useful and useless stuff. So we (isticktoit) found some useless stuff on Heise open: A Linux Retro-Gaming distribution and thought about bringing some old stuff up to ‚waste‘ some hours.

In this case I tried the new release of the Lakka distribution, which is mostly for Retro/Emulator-Gaming. It contains a lot of emulators from Atari up to PlayStation and Nintendo.

How to use Garmin Swim with Linux

Sport watches like the Garmin Swim or Forerunner-series are widely used. As a Linux-User, I was facing the „problem“ how to get the data on the PC from my Garmin swim (and to GarminConnect) … there are a lot of solutions around on the internet (some very old ones) – the following workflow works fine for me to get the data on the PC and upload it to GarminConnect.

Docker a nice tool for developers

Docker is the world leading software containerization platform. I tried using GitLab as versioncontrol system and Jenkings as continuos integration system but the system turned out as not completly useful.

In that way a colleague told me about a system he wants to create based on Docker.

What we want:

  • a git system under ouer control
  • a continuos integration that is flexible and customizable
  • every system available per SSL connection

Git Service -> GoGs – Go Git Service

It’s a simple self-hosted Git servise.

  • easy to install, cross-platform, lightweight and OpenSourse

It contains everything importent to develop something in collaboration.

Continuos Integration -> drone

It’s a continuous integration platform build on container technology. Every build run will be triggerd by a push to a repository if it’s linked to drone.

  • flexible and customizable: by setting up a config file you tell drone what is to do

SSL -> NGINX as reverse proxy

It’s a fine powerfull tool and a nice reverse proxy. With it we are able to provide the GoGs and the drone to the internet more secure and with SSL encryted.

We will colleced the SSL/TLS certificates from a Let’s Encryt service.

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

screen

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

raspi-router2

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.
