+====== NETLESS3 workshop, Athens ======
+Workshop took place at Frown, Athens - http://www.frowntails.com/technology/netless-workshop/ \\
+Photo log - https://www.flickr.com/photos/datenspiel/sets/72157634042359069

+Following firmware was run on TP-Link MR3020:
+{{:netless3-10-factory.bin.zip|}}
+{{:netless3-10-upgrade.bin.zip|}}
+Data collected on netless node devices. It contains username, message and time at which two nodes interconnected.
+Since the devices don't keep real time, the represented time is relative to the moment when device was powered on (seconds from boot).
+In both attempts the devices' time was (more or less) synced by powering-on all 10 devices at the same moment.
+To convert relative time we first need to turn the time at which devices were power on into unix time stamp:
+  date --date="Wed May 22 19:32:02 EEST 2013" +%s
+  (prints "1369240322")
+Then add seconds value to this timestamp and convert back to usual time format:
+  cat alex-log1.csv | sed "s/,\([0-9]\)/;\1/" | awk 'BEGIN { FS = ";"} { print "alex;"$1";"strftime("%F %T", $2+1369240322) }'
+This is what we get:
+  (original data from a node:)
+  netless power,1938
+  (converted data:)
+  alex;netless power;2013-05-22 20:08:35

+The previous files contains also data from GPS devices.
+Merging GPS data with the data from netless node devices, a video visualizing our second walk was created:
