calum.org is hosted on a linuxvps.org Linux Virtual Private Server. Why not get your own?
Now that I've started writing little apps for phones, I occasionally get excited by one, and send a link to some people.
They get an SMS from me with an URL ending .jad, and a message urging them to install, and run it.
Some do, some don't - I suspect because they're suspicious about it.
Hell, if I didn't know about phones, and permissions, I wouldn't. No way. I'm far too suspicious when it comes to things like that.
