Just received my Dock Connector-to-VGA adapter. Let's see if I can mirror the editor on an external display (beamer).
Well, this is an interesting read regarding US export regulations for encryption algorithms: http://blog.theanimail.com/iphone-encryption-export-compliance-for-apps

And this is just for using a HTTPS connection, not SSH. (the process is probably the same though)

The paperwork involved is quite heavy and takes a long time to complete: http://zetetic.net/blog/2009/08/03/mass-market-encryption-commodity-classification-for-iphone-applications-in-8-easy-steps/
This is fixed in 1.1 which is currently in review at Apple. It should hit the App Store very soon.

In this version, all supported file extensions are registered as text files in the system.
Well, I sure find it interesting :)
I've already asked Apple for permission to use the Monaco and/or Menlo font. They are they copyright owner of those fonts. The iOS developer support gave me a contact to ask. Unfortunately I didn't get an answer yet. That was a few weeks ago.

I also tried to disable anti-aliasing when drawing the characters. It seems like you can't disable it on iOS when using CoreGraphics to draw the glyphs.

The DejaVu font is very similar to Menlo. They are both based on Bitstream Vera. In Mac OS X 10.6 Snow Leopard, Monaco was replaced as the default Terminal font by Menlo:

I played around a bit with ideone.com, but it was quite slow to respond.

I tried to compile a piece of C# source code I had lying around, but it didn't have the Windows Forms assemblies as it uses the Mono compiler. So it was pretty useless for C#.

For things like PHP or Python it might look different though.

Currently, I'm not quite convinced that it would be a really useful feature.

I thought I can use it as a way to check the syntax of files without actually running the code.
Thanks for pointing that out!
