I still do it on paper for non-recurring tasks. Big list with all the things I need to do for work. Small dated list with things I need to do today. Each morning I look at the big list, extract what I want to do that day, and write a new small list on a fresh page. When things come up during the day, they go on the small list if they're urgent and the big list if they're not. At the end of the day I cross out tasks on the big list if they're done (and add undone urgent tasks to the next day's small list).

For recurring tasks and meetings I use a calendar.
