Bug #317781 - Comment #45 - very interesting analysis of the data loss problem with ext4. Summary: crap applications and libraries. Unfortunately, it also affects parts like sqlite (though only performance) and unfortunately larger parts of Gnome and KDE, which is why kludges are now being introduced in ext4 to work around them.

.epub eBooks Tutorial - how to produce ePub files with free software.
Feedbooks: Food for the mind - free eBooks in ePub format (can be used with the Sony Reader)
Fictionwise eBooks - and this is my favorite eBook dealer at the moment, delivers various formats and offers useful search functions also by format. Also there are the LRF files best suited for the Sony. Nice: there are also quite current titles and with their software you can also read the books on the iPhone. Unfortunately, many publishers are being difficult, so for example you can only get the books by Neal Stephenson in DRM-crippled formats, none of which are compatible with the Sony.
macvim - Google Code - another VIM version for Mac, but one with better support for various Mac techniques. And better integration (e.g., many standard keys are supported). In addition, it is based on the current version.
:: Munseys : A Bangsian Fantasy - and another site with tons of free eBooks - here you'll also find ePub and lrf formats (the latter often works better with the Sony than the ePub format, at least if it's not explicitly made for its small screen).
