Re: Transducers are Coming

Thank you for another great technique and concept!. I've been using reducers a lot lately and I've found that it is in some cases better (performance, fold support) to wrap local state in the intermediate result, rather than to keep it in an atom. See this *very* simplified example for compari

Re: Can I compare ::logging from one namespace with ::logging from another?

Keep in mind that :: is just a syntax sugar that is processed by the reader, before the compiler kicks in. ::foo is a shorthand for :your.current.ns/foo. Its purpose is to make it easy to create keywords that do not clash with other ones. Keywords are equal (and identical) only when both of th

Re: What to use for serializing reference types?

Assign a unique name to the prototype object. Serialize instances as map and put the reference to the prototype object under one of their keys. Something like {:prototype-components {:r10k {:resistance 10, :type :fixed, :unit :kΩ}} :components [{:name "resistor 1", :proto :r10k}, {:name "resistor

Re: Transducers are Coming

This is not safe usage, as you are not calling the 'flushing' method or handle reduced objects. Correct use would be (def xform (comp (filter odd?) (map #(* % % (def strip-reduced [x] (if (reduced? x) @x x)) (let [r (xform conj)] (strip-reduced (r (strip-reduced (r #{1 2 3} 7) ;=> #{1 3 2

Re: how do you name your protocols?

I use IBlah (camel cased, prefixed with capital i) in both Clojure and ClojureScript. It looks better than PBlah and is consistent with how ClojureScript names its protocols. Jozef On Fri, Sep 5, 2014 at 11:52 AM, Dave Sann wrote: > I saw a comment on protocol naming here: > https://groups.goog

Re: how do you name your protocols?

Clojure API exposes types to the user (Agent, Ref, Var, ...), so it is benefical to see on the first glance whether the name is of a type or interface/protocol. If the API would be built solely on the protocols/interfaces, those prefixes would be of less use. Moreover, I think that names of types

Re: [ANN] Clojure 1.7.0-alpha2

FYI transients no longer enforce thread locality, and you may now call them from any thread [1]. More options for handling mutable state is not a bad thing (as Clojure is a practical language), though more discipline will be needed. Jozef [1] CLJ-1498 On Thu, Sep 11, 2014 at 9:41 AM, Arnout Roem

Re: [ANN] async-sockets - work with sockets using core.async channels

One way how to handle this elegantly in Java is to add support for java.nio.channels.SelectableChannel in core.async buffer. That way you could select on any combination of core.async channels and io resources, waiting for core.async channels to free and resources to have data ready. Jozef On Wed
