Oops, I just noticed that I forgot to blog about one recent Effective Concurrency column: “Writing Lock-Free Code: A Corrected Queue” which also appeared in the October 2008 print issue of Dr. Dobb’s Journal.
From the article:
As we saw last month , lock-free coding is hard even for experts. There, I dissected a published lock-free queue implementation  and examined why the code was quite broken. This month, let’s see how to do it right.
Here is the complete-as-of-this-writing set of links to the published Effective Concurrency columns. As always, the months reflect the magazine print issue dates; they usually hit the web a bit sooner:
