As a coder, I ofently use services like pastebin for sharing code snippets. I recently discovered the 'Paste Selection Online' function in the TextMate bundle, which lets you paste the currently selected code to TextMate's Pastie page. I've been using it with success from home, but I could not connect to the server from my office, as I am behind a web proxy.
I found I could fix this by opening the TextMate preferences pane. In the Advanced section, select 'Shell Variables,' and add a variable like this:
Variable: http_proxy, Value: HOST:PORT, where HOST is the address of the proxy and PORT the port the proxy is listening on.
That's it. Note that I didn't need this for working with the Subversion bundle, as svn was already configured to use the proxy.
