## Welcome
CoSin is short for Chaos Singularity. We are not quite sure what that means, but
we do know, what we want with it: We hope to provide a chance for geeks, nerds,
hackers, discordians, chaots and other interested or curious people, to meet,
learn, chat, have fun and relax. During three days, we'd like to offer the
opportunity to investigate technology, think about its effects on society, or
just chat with other participants in a relaxed atmosphere.

## Keine Cosin 2020
Liebes Chaos
Leider macht Corona auch vor der Cosin nicht halt. Da wir in der Villa Ritter den Mindestabstand sicher nicht einhalten können, müssen wir schweren Herzens die Cosin für 2020 absagen.
Wir haben uns lange Gedanken gemacht, Pro und Contra diskutiert und irgendwie auch bis zu Letzt gehofft, dass sich die Krise vielleicht doch schneller wieder legt. Im Sinne einer fairen, transparenten
Kommunikation und um klare Verhältnisse zu schaffen, was z.b. Planung, Beschaffung und Unterkunft angeht, erfolgt dieses Mail zum jetzigen Zeitpunkt.
Für die GV wirs sich der Vorstand noch beraten, evtl. gibt es hier eine digitale Lösung. Sobald wir dazu mehr wissen, werden wir sicher
wieder informieren.
In diesem Sinne: Hebet nech Sorg, blibet gsund

## What is CoSin?
CoSin is a technical and political event, where we intend to hold lectures,
operate a network and have a lot of fun. Lectures are going to be in German and
English (in the past mostly German). CoSin is a non-profit event, and generally
chaotic when it comes to our goals. Originally, we just wanted to offer an event
for geeks, hackers and other friends of constructive chaos, to meet, chat and
have fun. As such, the event follows a strong do-it-yourself principle,
i.e. visitors are not consumers, but participants.
As a courtesy of the political reality, which seems to differ more from our
ideals - like freedom of information and protection of privacy - each year,
there is also an ever growing amount of political content. As such, we also hope
to provide an opportunity for people with technical and political background to
meet and exchange thoughts.
Finally, CoSin is also a good chance for people without technical background, to
gain an insight.
## Topics
The content of the CoSin event depends on the participants. Some topics are:
* Software (e.g. GNU/Linux, BSD)
* Hardware (e.g. Wireless Routers, amateur radio)
* Electronics (e.g. soldering workshops)
* Mate
* Religious wars (Vi vs Emacs, etc.)
* Politics (especially information and net-related topics)
* Fun
More specific information about talks and workshops can be found in our

[schedule ]({{< relref "fahrplan.en.md" >}} ). Besides sharing knowledge
and experience, CoSin and the organisations behind it also pursue various
long-run objectives:
2018-04-23 04:19:59 +02:00
* Networking between groups of different geographical areas.
* Support of free projects around technology and information politics.
* Advancement of information security.
* Creation of a broader consciousness for opportunities and risks around
information society.
* Investigation of new technologies and analysis of their impact on society.
* Understanding the interrelation between technology and information freedom.
Furthermore, CoSin is also meant to offer an opportunity to get to know people
and their projects in a relaxed atmosphere.
## For Whom?
CoSin is open to everyone, who is interested in technology and it's effects on
society. You don't have to be an Unix guru to participate - all curious people
are welcome. We'd be happy to meet you at CoSin!
## What does the Name mean?
A [singularity][1] is a particular point in time and/or space, where everything
concentrates (e.g. a black hole - a gravitational [singularity][2]). Chaos
Singularity could therefore be a concentration of all chaos. A [singularity][3]
can be something strange, unusual, peculiar or unique. Furthermore,
[singularity][4] is the point in time, where the exponential growth in
technology becomes infinite. At this point, all development happens extremely
fast and almost completely chaotic, making any predictions about the following
time impossible.
Cosine is a trigonometric function. It does not have any [singularities][5].

The value of `cosin({{< cosin "date_year" >}})` is approximately {{< cosin " cos_value " > }}.

## Who organizes CoSin?
CoSin is a chaotic event organised by [Chaostreffs][6] of Switzerland.
These groups share a common support for the German [CCC e.V.][7] and its ideals,
in Switzerland represented by the [CCC-CH][8].
The content is provided by all sorts of persons. Everyone is invited to
contribute to the program, and we are grateful towards all the people who do
this every year.
