Now this is cool. An Operating System written totally in JavaScript. And it’s not just an emulator; but it actually fully works in JavaScript. It features a filesystem and various UNIX commands such as cat, vi, which, ls and set. You’ll have to check this out because it rocks!
After finding this useful document about the Maildir format I was finally able to complete my ‘How many mails do I have’ oneliner:
expr `find /home/username/Maildir/cur -maxdepth 1 -type f -regex '.*,[^S]*$'|wc
-l` + `find /home/username/Maildir/new -maxdepth 1 -type f|wc -l`
Might be useful for some people who think this kind of functionality belongs in a webmail client 
Currently, Google returns 459.000.000 results when you search for the word ‘blog’, so I thought now is a good time to start another one. Unfortunatly, the number of hits will probably not increase to 459.000.001 with the start of sjon.blog; but I’ll give it a try anyway. If you are reading this, I was probably able to provide a steady flow of entries which might have been usefull and you are now searching through the archives finding the first post (which is this one, even though I left the Wordpress default message as well, but consider that post #0, and this #1). Congratulations, you found it!
I don’t know where this will end; but at least this is what it started with!
