When reading the newsgroups I follow in Thunderbird, I always like the most recent messages to be displayed on top. However Thunderbird adds them on the bottom by default. No problem there, however when resorting the column, it unthreads the messages, so you need to group them together again. Why? because a setting in thunderbird tells it to. So, in the Options on the General tab, select the config editor and change the the value of mailnews.thread_pane_column_unthreads to false. Now, when resorting the messages by hitting the column title, it keeps all of them grouped by thread.

Documentation is so very important when writing software. But some never learn: They write their documentation in Word! You can't make a worse choice. Luckily these documents are easily converted to the DocBook format. Infinite-loop made a java application called upCast to do the job. It converts Word documents to DocBook , by saving them to rtf first. Once you have a DocBook version of your documentation, you can start publishing it in whatever format you want using xslt stylesheets. A nifty little program, called DocMan, can process DocBook into html, xhtml, pdf, chm. In other words, you have one source of your documentation and different output formats.
