How many times have you had to copy/paste code into a chat session? or had to email files?
Try out PasteBin … it incredibly simple and extremely useful.
Lets you just paste code online, and then other users can easily modify it.
Others just go to a simple url, like http://some_name.pastebin.com or even http://pastebin.com/4213124
You can then view changes and perform a diff to check what was changed.
One drawback is the lack of security on this. So anyone else could hit the same url and view your code too.
But usually such debugging sessions have too little code to give away any real knowledge of the system.
I loooove it!
