New Functional Programming Job Opportunities

Re: some guidance sought

Oh! The Java collection methods! For interop with Java, I'm guessing. Not a personal priority, though I see that data.int-map does exactly that. The Clojure interfaces are much more reasonable. And really I want to focus on the extensions to AA trees that I've developed, like virtual AA trees

Re: My first Clojure program (and blog post about it)

Your way works because basically you are building two extra vectors which are implicitly getting destructured, but that's syntactically noisy and also a lot of extra computational work that is unneeded. -- Thanks! I cleaned it up a bunch:

Re: some guidance sought

I had not heard of AA trees before, but according to Wikipedia they sound like a variant of red-black trees. Clojure's built-in sorted-map and sorted-set implementations are called by the class name PersistentTreeMap in its Java implementation [1], and it implements a persistent version of a

Re: Hashing With Consistent Results

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, I am the author of https://github.com/whilo/hasch Would calling hasch.core/edn-hash satisfy your performance requirements? I tried hard to make the recursion of the protocol performant, but hashing a value is slower than the time needed to write

Re: why does this file watcher keep triggering?

I'm glad that sort of thing doesn't just happen to me :) Sent from my iPhone On 10 Aug 2015, at 00:44, Lawrence Krubner lawre...@rollioforce.com wrote: Okay, I am an idiot. I had the directory watch setup to watch the directory where the uberjar was built, so of course it was triggered

Hashing With Consistent Results

Hi, I need a way to reduce a compound value, say {:foo bar}, into a number (like 693d9a0698aff95c in hex). I don't necessarily need a very large hash space, 7 hex digits is good enough for my purposes. But I need this hash to be consistent between runs and JVM versions etc. So I guess that rules

Re: Manifold streams/deferreds raising errors downstream of a sink

Hi Andy, I would provide a function that wraps put!. It would still return a deferred, but not the result of put!. It would create a deferred, representing the result of the computation and pass it down the stream together with the input. Consumers would set its value once the computation is

Re: Anotating functions for pre-processing

thanks for all the useful replies. I underwent some pc migration so could not answer. to all that suggest that I rethink the use case — I am fully aware of libraries like tools.trace and this approach (with-xyz ...). I am also aware of function composition and I enjoy it in many places, but
