Yes. I used to get nearly all of my programming information from books or at least tutorials. Now I get nearly all of it just from resources scattered around the web.
I've never read a book on programming. I read books for certain things: I love books on marketing and I'll probably read Tufte in hard form, I have a copy of his stuff. But for programming I learned almost exclusively online: nowadays, I use the online books that Coda provides.
To be fair, I'm not a brilliant programmer. So I don't know if I'm missing out by learning online.
at lets you specify dates as day/month/year. All you have to do is make sure the computer is running at that time, which is easy if you do this on your mail server.
