You know, with how much people tout the prism2 chipset, atheros sometimes gets looked over.

blam.
I mean, it’s got interfaces to act as vaps, to go in rfmon mode… pretty cool. I haven’t figured out how to reach the full potential of my prism2.5 card yet though, so I guess I’ll need more experimenting with both

Here are some flags that may help vulnerable code from being executed.
-D_FORTIFY_SOURCE=2
This should get rid of some buffer overflows that can be analyzed statically and some obvious ones (strcpying input, format string vulnerabilities).
More information can be found here: http://gcc.gnu.org/ml/gcc-patches/2004-09/msg02055.html
-fstack-protector-all
From the man page:
Emit extra code to check for buffer overflows, such as stack smashing attacks. This is done by adding a guard variable to functions with vulnerable objects. This includes functions that call alloca, and functions with buffers larger than 8 bytes. The guards are initialized when a function is entered and then checked when the function exits. If a guard check fails, an error message is printed and the program exits.
(this is enabled by default in recent versions of Ubuntu)

Using ffmpeg, anything’s possible
Just install ffmpeg, lame, and then you can do something like
ffmpeg -i flashvid.flv -ar 44100 -ab 160 -ac 2 outfile.mp3

It’s easier than you might think.
socks is actually built into openSSH, so its really a trivial matter to setup a local proxy.
$ ssh -D 12345 myuser@remote_ssh_server
will open up the port 12345 on localhost as a socks proxy and all your traffic can be specified to go through the tunnel and out of remote_ssh_server
For firefox 3, go to Edit->Prefrences->Advanced->Network->Settings
and set it to use a Manual Proxy, localhost, port 12345 socksv5
