Programming on the iPad?

I think you need something like this:
\rideone.com

brainfuck.tk/
\rtry-python.mired.org/
\rlibrenix.com/?inode=7858
\r
In the end this is Team Viewer, if there is a normal network under the arm and connect to the normal machine.

you can connect to the remote computer using, for example, parallels.
And since the computer can do anything.

I guess that can be in the form "via ssh on the remote server that something is correct, being out of town". For normal development it is more expedient to monitor more and more resources, not to mention multitasking.

Bespin from Mozzila likely to help. I also saw something like — SFTP (ftp over ssh) + local editor on the similarity of Vim. The easiest option is to ssh + vim. Of the ssh clients I recommend iSSH, IMHO the best client for iOS.

What language You want to program? If signatures on a clean, you can jailbreak your iPad and pull from cydia to put the gcc from the console to use it (put the ssh server and client and connect to localhost and to work).
If in PHP/HTML/JS/etc... then you can write code in any text editor and ssh/ftp to upload to your server for testing. Somewhere in cydia, I even saw a php interpreter...
If you want something more serious, with a GUI, and so forth, it is likely that the above-described variant with teamviewer'Ohm fits best. Although, no one is stopping again in a text editor to write code on the way to work, and are already at work to build/run/test.

Here is a great and complete overview of the development tools, sites on an iPad.
