Abbenay Hackerspace – Call for Support

The Abbenay hacklab [1] opened early this month in Stockholm [2], where a
housing crisis is at full blow.

We are set up in a place that was squatted downtown by Kommando Carl Bildt
since late August, called AK4. The house was empty since June, and there was
no plans to use it until one year and a half.

Unfortunately, squats are very unusual in Sweden, and the discussions with the
landlord and the city of Stockholm are extremely difficult, even though many
newspapers speak positively about AK4. The place currently sets a record for
the country, with a life time of one month (and counting) while most squats
usually get raided by the police in a few days.

We are however facing an imminent eviction threat and police pressure has been
significantly increasing lately – with civil cops coming very often to take
pictures of the house and sirens waking us up early in the morning.

This call is asking you to contact the landlord to show support to the hacklab
and the squat. So far, he has been very closed minded. He only proposed that
we leave the place and talked about an expensive and abusive rental contract.
It was about a much smaller office, and according to which we would not be
allowed to sleep in the premises, we would not be allowed to host concerts,
cafes or parties, etc.

The landlord is Fredrik Winberg; he is the CEO of Cementa AB [3], part of
HeidelbergCement Global with a revenue of 15 billion euros per year. He also
runs the Biteam AB company [4].
We do not believe that he or any of his fellows will turn poor should we
definitely get the house in Stockholm, and we think that his behavior is
basically motivated by the capitalist idea that the right to stay somewhere
must always be paid for.

We hereby ask you to contact him to expose your views on squatting and
hackerspaces in order to give him a more comprehensive view on the subject
than what he could have had as a capitalist entrepreneur. His contact email is
fredrik.winberg at cementa.se and he can be reached by phone at
+46 (0)708 25 68 04 (NB: this contact information is available from the WWW).

We do not give a “copy and paste” email to send him, since mail bombing would
probably not be effective and only increase tensions. Also, please do not be
aggressive nor engage in any other activity (defacing etc.) which would not
lead anywhere.

You are also most welcome to join the AK4 Squat Support Group on Facebook:

Thank you,
The Abbenay Hacklab

Linux and network security basic workshop at Abbenay

aw2We start with an easy workshop at the newly born Abbenay hackerspace in Stockholm.

Join us on Saturday October 3rd at 15:00 for an introduction to using Linux and free software.
Bring your laptop and thanks to the Backtrack Live-CD, you will be running Linux without touching anything on your hard disk (no installation, no modified file, etc.).
Once you have the basic knowledge, we will set up a weakly secured Wi-Fi network into which you will be invited to break.

Linux and security gurus are also invited! They can help beginners and the workshop is also the perfect occasion to meet them, looking forward to bigger projects!

Location: AK4 squat, Lövholmsbrinken 4, Stockholm.
NB! This event is hosted in a house that we occupy without authorization, come at your own risk.

Milkymist IRC channel

There is now an IRC channel for discussions about the development of and support about the Milkymist system on chip and videosynth platform. Feature requests, questions, general support, bug reports, patches, writing software for the chip (even if unrelated to the initial application), EDA tools and methodologies, technical questions not answered in the documentation, reusing Milkymist’s IP cores or software in your own open-source project, contributions, and anything that does not fit… can be directed to that channel:

#milkymist on the FreeNode network (irc.freenode.net)

You can also access the channel over the web using the link on this page.

Sanobot data for the first half of September

The CSV data from Sanobot for the first half of September is now available here: sanobot_half_sept.csv. Sanobot is the toxic gas sensor and Twitter bot of /tmp/lab.

Plot of the CSV

Plot of the CSV

The first column of the CSV gives the Unix time at which the measurement was taken. The other two columns are the ADC output for respectively the TGS2602 and the TGS2600.

For information about how to interpret the data, see here: http://lekernel.net/blog/?p=509 and http://lekernel.net/blog/?p=517.

Using the full CSV data, we can now try to figure out when is the best time to trigger the Twitter alert. For now, it posts a new alert when one value varies by more than 30% compared to the last posted.

NB. The huge peaks are because of people playing with cigarettes near the sensors. Smoking kills.
