Double blind reviewing is not the norm in computer science. You will sometimes see it, but it depends on the subfield, the specific conference/journal, and even the year. In my experience as an author/reviewer, the submissions have been anonymous maybe 10% of the time. And the biggest issue I see in CS is the focus on gatekeeping. When many (most?) papers are published in conferences with a single round of reviews, peer reviewing becomes more about accepting/rejecting the paper than improving it. The average review I receive in bioinformatics is more useful to me than the average review in CS.
