Sometimes also, the output that ends up in the file is a little odd, too. I tried to put 42 and I got * instead. When I use the writer without the core.async functions, it works as expected.

Wow! I had no idea about the daily specials mailing list. I have joined now though, so if I see a JOC special pop up I'll snatch it up.

Re: core.async and Joy of Clojure
Nice to know about the 7 models book. I wasn't aware of it. I can't give you an opinion about JoC 2nd vs. 1st ed., though. I haven't read either thoroughly. I only got the first edition when I bought the pre-release 2nd edition package last fall. I don't have an e-reading platform that I like, so I have only been reading bits and pieces of either edition. I'll read it seriously when the paper edition comes (unless I buy a tablet first). (Are you on the Manning Publishing daily specials mailing list? That's how I got the pre-release package for 1/2 price, and I have seen that offer more than once since I bought the package. It may that at this point they won't offer any further 1/2 price deals on JoC, but if they do, you could buy it that way.)

Re: core.async and Joy of Clojure
Thank you Mars0i!! I have a first edition copy of JOC and really like the way it just lays things out for you. I am hesitating to buy the 2nd edition, though, due to the hefty price-tag, though I am curious about logic programming and data. Would you say it is worth the money? I am now reading the 7 concurrency models in 7 weeks beta version (recommended by Alex Ott, above) and am finding it thoroughly enjoyable. It masquerades as language agnostic, but the first half is virtually a Clojure book in the way it introduces Java's concurrency solutions (or lack thereof), priming you for the subsequent chapters that go into Clojure's primitives, core.async, and even Clojurescript. There is a chapter on actors, using Elixir, and then the latter half gets more general talking about how concurrency relates to big data and Hadoop, using Java. In general, I think all of the information is pertinent for a Clojure programmer who wants to become more well-rounded on the subject.

Re: core.async and Joy of Clojure
Thank you Timothy, I did watch that talk! In fact, it was one of the videos that really piqued my enthusiasm in core.async. I had no idea that the code was available on github. Good news. I am thinking now about how I could use core.async to do useful/fun things: web-service or browser game, simulation, etc. It will be exciting to see how things develop in the next couple of years. Do you think you might put out a book about some of the stuff you've been working on?

core.async and Joy of Clojure
Hey guys, I have studied the sample code snippets on the github page, read through several tutorials and watched many talks on core.async, but am still unable to effectively implement this library in my programs.

Are there any good resources out there that can bridge the gap between code snippets and show how the concepts of this library pertain to system design?
