Back from HAR2009

I have just arrived from HAR2009 which was a very awesome event! We were camping for 5 days, drinking beer and attending lectures. Some of us visited Workshops, but sadly I didn’t. I probably was too busy attending talks and visiting the Toasti booth ;-)

The CCC has built up a great Dome as well as a big tent for hacking. CCCHH brought Milliways, the last pub at the end of the universe and it was a really cool place to hang out. There were many people from different countries which made it really interesting and enjoyable to just be there. Last but not least, the beer was great ;-)

Others have brought a GSM Network! How awesome is that?! Harald Welte and his fellow GSM-Tent members have set up the “42” Network and we were able to place as many (internal) phone calls and SMS as we liked. Of course, we started to script that ;-) So I found out, that sending an SMS via a serial connection to my phones modem is as simple as the following lines:

import serial
import time
DEVICE = '/dev/ttyACM0'
def send_sms(nr, msg):
    ser = serial.Serial(DEVICE, 115200, timeout=1)
    line = ser.readline()
    line = ser.readline()
    assert line == "OK\r\n"
    line = ser.readline()
    line = ser.readline()
    assert line == "OK\r\n"
    ser.write('AT+CMGS="%s"\r' % nr)
    ser.write('%s\n' % msg)
    lines = ser.readlines()
    print lines

Sadly, I couldn’t hack more with the GSM network because it was shut down rather early and I didn’t use my computer much during the lecture time. So next time I’ll try to reproduce the Curse of Silence and play around with PDU SMS.

So I have been to a lot of interesting villages and I met some interesting people but sadly GNOME people couldn’t make it. Maybe we’ll have a GNOME Village next time… :) If you are interested in how the camp looked, watch this impressions movie or click through the media.

The next CCCamp will probably be in two years and according to rumours it’ll happen in Finowfurt again. I’m really looking forward to that event!

Taxi from Hamburg to HAR2009

Pre-Sense is sponsoring a bus ride for up to 30 people to the HAR2009! The way back to Hamburg is sponsored as well. Also, you can win two HAR tickets! :)

HAR Plakat

It’s very kind of that young company to sponsor that trip and thus enable young hackers to meet with the brightest people in the IT-Security area. I wonder if they hope that some of these young hackers will take one of their open positions in the future ;-)

Anyway, feel free to register for the bus ride or win a ticket. The details can be found at

Your HAR2009 Tickets

I received my ticket for the HAR2009 which takes place from August 13th till August 16th somewhere in the Netherlands!

If you buy your ticket until 2009-03-31, you’ll get a 25 Euro discount. If you additionally use the code “SURFBIRD”, you’ll get additional 5 Euro off. That translates to 150 Euros for a ticket.

I hope, it’s going to be an awesome CCCamp this year :) I’m really looking forward to this hackers holidays.
