I don't see how this could be used for collaborative code editing. Is there an example of this?

Yup! http://www.firepad.io/examples/#code

Atlassian[1] and Action.io have already built stuff with it.

cool thanks

some bite sized emacs tips http://rawsyntax.com/blog/categories/learn-emacs/

and a great introduction to setting up emacs http://batsov.com/articles/2012/10/14/emacs-on-osx/

can you give an example of how this is really a problem? I have an iPad that can display PDFs. When I scan documents PDFs get created.

I am aware that I am free to use UIWebView based browsers, which are slower than Safari and just as crashy. Freedom!

its not difficult to maintain. Emacs in particular has M-x align-regexp = (which does the alignment for you)

when you migrate, you may want to setup jekyll to handle your redirects (from your old site's url structure)

I wrote about a jekyll plugin that allows just that (used it when I migrated away from tumblr)

Thanks! That's a useful solution; the Posterous importer I used added a permalink, IE "/path-to/original-post" in each post's header. Worked reasonably well.

it degrades to select / option boxes. The demo page sucks, but I have used this and it works fine without javascript.

yes this is exactly right, its POST for compatibility reasons, rails puts a special parameter in the form submit to map to PUT (for resourceful routes)

html5boilerplate used to be my goto html / css structure for starting a project. I recently build one using bootstrap 2.0... and it was significantly less hassle, but still looks good and works on desktop and mobile

shouldn't that be #!/usr/bin/env ruby

Using absolute paths is still perfectly acceptable. Wikipedia covers the basic benefits/drawbacks:

For example, Comix uses #!/usr/bin/env python, even when it's installed by the package manager (at least on Ubuntu). This means that if I launch it from a terminal with a virtualenv enabled, then it blows up because chances are that I don't have pygtk on that virtualenv (because I generally don't work on GUI apps). At the very least, things installed by the package manager should point at the interpreter that is under package management.
