Allan Giddy’s Earth v Sky project is approaching delivery. I’ve taken our test runs from King St wharf and post processed them for colour. Here is a handy ImageMagick script to stitch sequential images in a vertical stripe.
whale:king st rossetti$ convert ribbons/*.png -append composite.png
If one wanted to append them horizontally instead of vertically one would [...]
A work in progress.
This documents our inhouse method for maintaining three tiered deployment with revision control
# create a backup of the database
# initialise an hg repo in your local dev directory, add all content, commit and tag
# clone it to our remote repo (first time only)
localmachine:source user$ hg clone ./ ssh://repo/laudanum/scanlines
# push updates to the [...]

In preplanning a project now underway I’d flipflopped every couple of days about the web framework that I thought I’d use for it. Discussing it in house on various occassions I’d managed to convince Cossioski one way and then another railing on avantages of one over another.

Who is hammering FTP on our server?
sudo grep “no such user” /var/log/syslog | cut -d[ -f 3 | cut -d] -f 1 | sort | uniq -c | less
What firewall rules do we have in place?
sudo iptables –numeric –line-numbers -L INPUT | less
How do we add to the rules immediately?
sudo iptables –insert INPUT 3 -s [...]
In September we ran a complete slice test of a Bluetooth annotation system for the Sydney Olympic Park Authority. The aim is to annotate public artworks that scatter the site using Bluetooth instead of convention didactic panels (signage to the layman).
We used small form MicroClient SNR computers running Debian and some funky Python scripts. The [...]
