Sometimes you just want to know which sites are hosted on a certain server. If the DNS server in question won't help you with that problem, this little script just might. It does a search on live of the form ip:<ip address> and just lists all the hosts that live can find. All these hosts will then resolve to the ip address you entered and should thus be hosted on the same server. Nothing fancy, but I find myself using it a lot.
I recently felt inclined to write a tool that converts an executable into a batch script. However, I was annoyed at the 64k size limit. So, how to get around it? For shits and giggles, implement a COM file that will decode base64-encoded binary data, glued to the back of the BAT file, and write it to a file on disk. Use the same DEBUG trick to extract that COM, and you have yourself arbitrary exe2bat conversion. This is useless but fun, and maybe you are curious about my idea of fucked up 16-bit assembler.
