Baltimore Node-Cam is currently offline. ♪
If you'd like to bring it back, bring it up at the meeting. :)
It never made it to the new space, for a couple reasons:
- Privacy
History[edit | edit source]
Phase 1[edit | edit source]
Phase 2[edit | edit source]
backup_images.sh :
#!/bin/sh OLDFILE=`md5sum /home/bnode/webcam-backup/$(ls /home/bnode/webcam-backup | tail -n1) | cut -d ' ' -f1` NEWFILE=`md5sum /home/bnode/baltimorenode.org/public/images/webcam.jpg | cut -d ' ' -f1` if [ "$OLDFILE" == "$NEWFILE" ]; then echo "Still the same" else echo "NEW!" cp /home/bnode/baltimorenode.org/public/images/webcam.jpg /home/bnode/webcam-backup/webcam-$(date +%Y%m%d%H%M%S).jpg fi
makeimagepage.rb:
#!/usr/bin/env ruby
`touch /home/bnode/baltimorenode.org/public/webcam.html`
out = []
File.open("/home/bnode/baltimorenode.org/public/webcam.html", 'w') do |f|
f.write("<html><head></head><body>")
f.write("<img src='images/webcam.jpg'><br><br>")
f.write("<ul><li>")
Dir.entries("/home/bnode/webcam-backup").sort.each do |e|
next if ['.', '..'].include? e
out << "<a href='images/webcam-backup/#{e}'>#{e}</a>"
end
f.write out.join('</li><li>')
f.write("</li></ul></body></html>")
end
puts "Linked to: \n* #{out.join("\n")}"
The directory /home/bnode/baltimorenode.org/public/images/webcam-backup is symbolically linked to /home/bnode/webcam-backup.
When executed from the directory containing the webcam still, this command will create a time lapse video.
mencoder -nosound mf://*.jpg -mf w=640:h=480:type=jpg:fps=5 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1000000 -o time_lapse-test.avi
Phase 3[edit | edit source]
- Haml for html templating.
- Atom feed of stored photos.
- Only store images for two days, archive the rest.
Phase 4[edit | edit source]
Write a Flex/Flash based image browser / replay tool.
