Autohotkey pastebin hosting and other things

[geek]

I'm currently running the irc pastebin (goes by the nick of PasteDude, found at http://ahkbin.no-ip.org/ ) off a spare ubuntu box at my home. I can't keep it hosted here forever. The problem is, it runs as a python script with several dependencies. I don't/can't really pay for a server to host it like I need it, and I don't think a system like it can be set up using standard server-side php. Am I wrong?

If anyone else wants to provide hosting for PasteDude, be my guest. It runs its own HTTP server, and, as I said before, requires ~3-4 dependencies. It runs on python 2.7.X

Should I move PasteDude over to #auto-hotkey? Should I try to implement a dual-channel system?

it is weird that it has some many dependencies... Post the source? maybe a fork can be made

Well, I have yet to figure out Git/Github or anything of that kind, so I'm really, really bad at sharing large code projects, as well as versioning. This is the python file, and there are a handful of other html, and css files.

And don't tell me my python is horrible. I know.

no it's fine... But that seems more compilcated then need be.
Why not just a simple php script with a key? dont worry, i dont think anybody is going to attack the server... ( i hope not )
Also, for the whole project, you could use Dropbox.

cheers

I wasn't aware that web-based PHP could run an IRC bot and keep it connected to the IRC server (respond to PONG & PRIVMSG requests). Also, already someone has tried to hack into the "php admin" and "mysql admin" pages, which my server doesn't have.

Edit: It's already in my dropbox. I should probably give it a dedicated folder, though. It's just floating in my generic "python" folder

awesome! check out here, good example: http://www.dreamincode.net/forums/topic ... ot-in-php/
