This is a cute illustration by Alex Noriega. I don’t know if TikiRobot and this robot would be compatible as friends (since TikiRobot is likely to be making mai-tais or tossing frisbees to dogs instead of eating people) but maybe he wouldn’t mind break-dancing.
Amazing living spatial systems. The complete title is “Peripetics or The installation of an irreversible axis on a dynamic timeline.” The short “entails six imaginations of disoriented systems that take a catastrophic turn”. Peripetics is a piece in six acts made by Zeitguised for the opening exhibition at the Zirkel Gallery. Sound design by Zeitguised with Michael Fakesch.
Upstart is Ubuntu’s init.d replacement. It greatly simplifies writing init.d scripts and has a great respawn feature similar to daemontool’s supervise or monit. And it comes with Ubuntu by default.
For some reason, almost no one uses upstart. Even Ubuntu’s services use traditional /etc/init.d scripts instead of upstart scripts. I think this might be due to upstart’s non-existent documentation. There is no man page for upstart, and multiple people I know who have read the online docs somehow missed the three important commands that control upstart jobs: /sbin/start, /sbin/stop, and /sbin/status!
Here is how it works: put an upstart script in /etc/event.d. Let’s call it /etc/event.d/foo. This script is now immediately available under upstart. Just type sudo start foo. That’s it.
I converted Ubuntu’s /etc/init.d/lighttpd script to a much shorter upstart script. The big advantage of this is upstart will restart lighttpd if it dies for some reason. This is what the upstart script looks like:
#this is an upstart script that starts lighttpd start on runlevel 2 start on runlevel 3 start on runlevel 4 start on runlevel 5 stop on runlevel 0 stop on runlevel 1 stop on runlevel 6 respawn exec sudo -u www-data lighttpd -D -f /etc/lighttpd/lighttpd-infobase.conf
That’s it! Save this script as /etc/event.d/OL-lighttpd, and then type sudo start OL-lighttpd. You can kill off the lighttpd process and it will get restarted.
If you want to configure your lighttpd to write out a pid file, you can use pre-start and post-stop script to prepare and clean up the pid file:
#this is an upstart script that starts lighttpd
start on runlevel 2
start on runlevel 3
start on runlevel 4
start on runlevel 5
stop on runlevel 0
stop on runlevel 1
stop on runlevel 6
pre-start script
#make sure there is a place to write the pid file (optional):
mkdir -p /var/run/lighttpd > /dev/null 2> /dev/null
chown www-data:www-data /var/run/lighttpd
chmod 0750 /var/run/lighttpd
end script
respawn
exec sudo -u www-data lighttpd -D -f /etc/lighttpd/lighttpd-infobase.conf
post-stop script
#remove pid file (optional)
#add server.pid-file = "/var/run/lighttpd/lighttpd.pid" to lighttpd.conf file to have it generate the pid file
rm -f /var/run/lighttpd/lighttpd.pid
end scriptIf you want to stop lighttpd, just type sudo stop OL-lighttpd. You can also type sudo initctl list for a list of all jobs under upstart.
I hooked up my first-generation MacBook Pro to my Samsung LCD TV with a DVI->HDMI cable. The mac was able to output 1920×1080p at 60Hz to the TV. There was noticeable judder when trying to view 24fps content. I searched the net and no one seems to have gotten their mac to output 24p to their Samsung TV.
OK, here is how to get your mac to output 24p to your Samsung series 6 (or higher) TV:
I’m mostly happy with my new TV (in true redneck fashion, I traded my pickup truck for it). I originally got a Series 5, but It could only do 1080p60, and I really wanted 1080p24, so I had to upgrade to the Series 6. Unfortunately, the Series 6 arrived with a dead pixel. I don’t know what to do about that..
