Monitoring and quality assurance of open wifi networks out of client view (midterm evaluation)

Hey everyone,
Now we are on the midterm evaluation. I would like to tell you what I have done so far and what will come next. In the first post [0] I explained the work packages. In this post I will come back to the work packages  and show you what I have done for each package.
The first sub-project was the hoodselector. At the beginning of the work period I did some bugfixing for the hoodselector so that we where able to deploy the hoodselector in our live environment. The hoodselector creates decentralized, semi automated ISO OSI layer 2 network segmentations. You can find a detailed discription here [0]. Retrospective I can say that the deploymend of the hoodsystem went without any major problems opposed to my first expectations. Currently we have 4 hoods active. Around Oldenburg(Oldb), Ibbenbüren, Osnabrück and Friesland. More hoods will follow in future. Open Issues can be find here [1].
The second sub-project was to create a propper workaround for building images with the continuous-integration (CI) system of Gitlab using make on multiple cores.
The Freifunk Nordwest firmware now has automatically built testing images that are not only build on a single core but can be built on multiple cores. And the architecture targets are also autogenerated out of the sourcecode. This makes it possible to generate images dynamically for all targets also including new targets that may come in the future. I implemented a small algorithm that manages the thread counter of make commands. I use the number of CPUs out of /proc/cpuinfo * 2 this means for each logic core will follow two threads. In example our server has 8 cores so the CI build process will automatically build with 16 Threads [2]. Here is an example of a passed buildprocess with our CI builder[3]. Actually it is not possible to build images with a high verbose output, because the CI logfiles will get to big. That makes it impossible to use the webfrontend for analyzing the buildprocesses. I opened an issues for this and discussed the problem with the gitlab developers [4].
The CI builder is very helpful for the developing process of the monitoring drone.
Following I would like to report about our first hacking seminar.
The first hacking seminar was on 28.05.2016. We started with two presentations. One about Wireless Geo Location and the second one about the Hoodselector. We recorded the presentation with our new recording equipment [7] bought using some of the money for the mentoring organisation and uploaded the recordings to youtube [5].
The first presentation was about geolocating with wireles technologies.
Based on the Nordwest Freifunk geolocator [6]

The second presentation was about the function of the Hoodselector

After this two presentations we had a smal disscussion about the presentation topics and than we started o
ur hacking session where the developers started coding on their projects.
Now all sub-Projects are finnisched and I will continue with the Monitoring Drone Project after I finish my Study exams. Also the date of next hacking seminar is set for 9th of Juli 2016. Again we will have two presentations. One on Gitlab CI and one about how to use our new Puppet Git repositories including the submodule feature. The presentations will be recorded and after the presentation we will have a coding session like last time.
