I may have to use this to communicate with the Arduino :

Gives serial access to PHP under linux, OSX and Windows (write-only under Windows).
This class can be used to communicate with a serial port under Linux, OSX or Windows.

I like this little Applescript proxy for use with the Arduino.

Basically it can interpret data (characters) sent from the Arduino and send them on to other programs

Control your Mac from Arduino, the easy way
A while ago I wrote a small app that would execute AppleScript commands depending on the data send from an Arduino board connected to my mac. I’ve been asked a few times to release it but it was just a quick hack. Now thanks to HyperWerk in Basel, I’ve had the time to fix it a bit for a student project. I’m releasing it to see what people do with it.

Just discovered a rather strange problem with our Airport Extreme.

I have not had any particular problem with the wireless connection in the house, but we started having problems with services such as iTunes and iPhoto seeing each other.

It turned out that I could not see any services using Bonjour.

Checking through logs it looked like the Airport Extreme base station was continuously broadcasting Bonjour services - possibly jamming the whole network (at least on the wireless side of the network).

Restarting the access point suddenly restored all services.

Benjamin has had a longstanding problem where the SyncServer takes most of the CPU on his computer - and not letting him sync to his iPhone properly. If he switched to a different login user all was ok.

So I cam across this possible fix :

OS X 10.5, SyncServer takes 100% of CPU
For the past couple of days a process called SyncServer started every 15 minutes or so and it would take over a 100% of the CPU on my MacBook Pro. Not quite sure what initiated this problem, but I found the remedy discussed in this Apple support case to be useful and apparently effective (well at least so far). I did have .Mac and BlackJack synchronization, so not sure if either of these applications caused this problem or not.

For a period of time Bonjour has stopped working on my laptop - but it did not become a problem until I needed to add a new printer. So I hunted around for a fix - and found this :

sudo launchctl unload /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist

sudo launchctl load /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist

which seems to have fixed it for me.
