At the time, there is quite some discussion regarding air quality and pollution going on in germany. Some cities, like Stuttgart, have to deal with high levels of fine particle emissions. That is why some people came up with a simple solution to build a sensor network for air quality. They provide detailed instruction on how to build your own air quality sensor for about 25 Euros. So, if you want to participate, just head over to luftdaten.info
Die Vorlesungszeit des Wintersemesters ist um und auch das Programm des “Arbeitskreises Homöopathie an der CAU zu Kiel e.V.” ist für dieses Semester beendet.
Erfreulicherweise ist damit aber wohl auch die Zeit des Arbeitskreises an der CAU insgesamt beendet.
Am 16. Januar 2018 fand erneut ein Termin der “Ringvorlesung” Homöopathie statt. Leider konnte ich selber nicht an dem Termin teil nehmen, aber das folgende Gedächtnisprotokoll wurde mir von einem Besucher zur Veröffentlichung zur Verfügung gestellt.
Another year has passed and that means another congress has been visited. This year the congress moved to Messe Leipzig instead of the CCH in Hamburg. I was sceptical about the new location in the beginning.
Heute findet die zweite “Vorlesung” des Arbeitskreis Homöopathie an der CAU zu Kiel e.V. statt. Das heutige Thema soll “Wechseljahre als homöopathische Herausforderung” sein. Hier sollte ein möglichst aktuelles Liveblog veröffentlicht werden.
Der Arbeitskreis Homöopathie an der CAU zu Kiel e.V. bietet heute seine erste Ringvorlesung an. Hier will ich versuchen das Geschehen möglichst live zu protokollieren.
I have been fed up with my old Wordpress-based blog for quite some time now. One factor might be the missing updates, but another issue was Wordpress (WP) itself. Sure, WP looks like a simple solution, if all you want is have a blog with some usable tools around it.
Okay, the 33C3 is over for quite some time and I didn’t write about it. Short form: I was there, it was amazing, I was sick afterwards.
I havn’t seen lots of talks yet, but here is my watchlist:
Just as a quick note here:
I originally planned to do my third part on DNSSEC with configuration hints using the popular DNS server BIND. At the moment I also use BIND for my setup.
Now I discovered the “Advanced Secuity Notifications” at ISC, which sells prior warnings about security issues in BIND. Personally, I don’t want to support this model.
Instead I am currently migrating to another DNS server implemenation, YADIFA, which I will then write about. But first I need to check my setup using this server.
As I already explained in Part 1, the current state of DNS is pretty insecure. The goal of DNSSEC is to improve this situation. Here is how that (should) work. I won’t go into cryptographic details here, but just show the general behaviour.
