I have just purchased "The Best Software Writing I" by Joel Spolsky.
I have to tell you I cannot wait to start read it.It is not in my native language which I usualy prefer to read in, but I don't mind.
Why? Because I have read a few reviews about this book.If you, by some reason didn't read it yet check here and here.

[update]
It is great book indeed.I haven'r read such a good position for long time.
Worth to buy? Definitely :-)
