RP-SMA antennas will screw onto SMA antenna sockets just fine, but won't actually work.
U.fl connectors are the work of someone very evil.
Decent wireless cards can actually operate surprisingly far without an antenna...
Look out for the voyage install script, it attempts to chroot into the installed directory and run several things. Not good if the Linux system it's installing from is on a PowerPC box.
You can't actually change the mode of a madwifi interface, you have to destroy it and create a new one.
Don't mess up the memory offset when trying to set GPIO pins - it generally results in something nasty happening in the I/O port space...
Full story coming soon.

OK. Here's the huge code release I said I'd do... a while ago.
In alphabetical order:
http://gm.stackunderflow.com/code/ae_ioctl_dump.zip
KisMac R146: - themacuser's patch to remove the "airport" tool from Airport Extreme passive mode channel switching. Large improvement in overall CPU load.
This was the code I was playing round with when I was implementing that. Based on the code from the bcm43xx linux driver project (someone worked out how to call the ioctls in the OS X driver - and there was a code sample posted that just did a self-test of the card... I made it do something useful). It calls the ioctls in the Apple driver. This simple app just calls all the ioctls that do something useful, and returns what they call.
WLC_SET_CHANNEL was the one that went towards R146.
There's also some kind of a script to run it and make it dump what it sees to a file...
http://gm.stackunderflow.com/code/arpscan.zip
Scanrand style asynchronous ARP scanning of a subnet, written in python...
http://gm.stackunderflow.com/code/b64.py
Quick and simple base64 user/pass decoder...
http://gm.stackunderflow.com/code/confreg.zip
The config register calculator for Palm, and it's source code. GPL licensed, but if you do anything with this, tell me.
http://gm.stackunderflow.com/code/datausagev2.zip
Datausage v2 and sources... same as above (GPL, tell me if you do anything)
http://gm.stackunderflow.com/code/getAPLocation_v4.py
GetAPLocation v4 - find an accesspoint on WiGLE and find where it is in the world.
Now supports scanning via SSID and BSSID (multiple results). Now uses the WiGLE API as well, instead of parsing the search results page.
Also supports KML output - so you can show that query on Google Earth after you've done this.
http://gm.stackunderflow.com/code/macfisheyequake.zip
The Mac OS X sourceport of Quake 1 with the FisheyeQuake mod added. Lots of fun.
http://gm.stackunderflow.com/code/midisound.zip
MIDI sound tester - iterates through instruments. Used when working on that MIDI signal strength code.
http://gm.stackunderflow.com/code/mobile.zip
Some half-written code for email alerts. Being a 3 customer, I get free incoming email on my phone. Put two and two together.
http://gm.stackunderflow.com/code/netshell.zip
Half-written as usual. Some kind of an attempt at a shell. Incorporates the ARP scanner above, and a show command that doesn't do anything useful.
http://gm.stackunderflow.com/code/plsconcat.py
Take some .pls files and stick them into one big one.
http://gm.stackunderflow.com/code/quartz.zip
Some experimentation in Quartz Composer - some really cool stuff in here, I suggest you check it out. Screenshots coming soon.
... and that's the end of it... for now.
