This is great. Thank you.

Such a great book! As someone who came from a non-traditional background, this book was very key in helping me understand operating systems.

Since there's a lot of quoting of studies on this topic, I hope that everyone reads this very informative (and long) blog post by a psychiatrist on SSRIs and their effectiveness:

Definitely agree with this one. It's called Algorithm Specialization on Coursera. I'm now on course 3 and it's definitely helped me a lot in thinking about how reason about algorithms.

Yes it looks like they do deduplication, based on the HTML source:

  for (var i in data[yr]) {
    var story = data[yr][i];
    if (seen_titles[story.title]) continue;
    seen_titles[story.title] = 1;
  // ...add story to list of stories
  };

Thank you for that link. I appreciate that he chose to intersperse the history of commands (such as grep!) within his explanation.
