Re: Advice for building backend REST services from scratch using clojure

Prismatic Schema is awesome for describing the (web) apis, does also validations & coersion. Using it in all web projects nowadays. If you are thinking of json apis, swagger is a great tool to publish out the documentation. For clojure at least these schema / swagger-aware web libs do exist: S

Re: Uberjar woes

I've come up with a fix after lots of fiddling, and I cannot quite explain it -- but it works! The component library involves creating records that implement the Lifecycle protocol. In every namespace where I implemented that protocol, I added a (:gen-class) to the namespace declaration. I also

[ANN] lein-fruit 0.2.0

This is a new release of [lein-fruit](https://github.com/oakes/lein-fruit), a Leiningen plugin for building iOS apps in Clojure. It does this by using [RoboVM](http://www.robovm.org/), a bytecode-to-native translator. The template in this version offers a huge improvement over the past versions

Re: Uberjar woes

Clout doesn't depend on any protocols in Clojure. The only protocol it uses is defined within the clout.core namespace itself. Problems like this are often caused by compiled class files on your classpath. Often they are in the target directory, which can be solved by a "lein clean". The :clean-no

Re: Uberjar woes

Hi Josh, My solution ended up being pretty lame: I stopped calling a function from clout, and the uberjar magically worked, as disappointing as that explanation is. As far as I could tell, the root cause of my problem was that clout depends on an old version of clojure (1.2, if I recall correct

+1 to this concept. Also, I don't live near a ClojureBridge workshop, or user groups. One thing I've been arranging is pair programming sessions, which may turn into something for helping folks meet each other and work on interesting stuff. But, it's a different approach. On Apr 11, 2014, at

Tom, Not sure if you every figured this out, but I'm having the same issue. In my case, the error points to the Lifecycle protocol in https://github.com/stuartsierra/component (com/stuartsierra/component/Lifecycle). It's a pretty barebones configuration. https://gist.github.com/jalehman/104

Re: Is it possible to give an atomic message?

You could use a clojure agent , that would output your messages on a separate thread, one by one. (def *logger* (agent 0)) (defn give-message [message] (send *logger* (fn [_ & [msg]] (println (format "%s: %s" (. time-format format (. (now) getTime)) msg)))

Hey Marcus, If you have Google Calendars, you can use that, and invite people to edit a particular calendar. It would start off as an honour system, so that people don't trample on each others bookings. But as Tom George points out, building such a booking tool, is a great project. Otherwise, I'm

Hello, Here's maybe the easiest way, with locking: (defn give-message [message] (locking *out* (println (format "%s: %s" (. time-format format (. (now) getTime)) message Of course, locks can introduce their own problems, so maybe the next easiest way is with the combination of agent

Re: Is it possible to give an atomic message?

You could do this with core.async. Make a channel that takes messages, and then run a go loop that pulls messages off the message channel and prints them. Then only one part of the program is ever printing. Any other part that wants to print a message can push onto the channel. On Fri, Apr 11,

No worries, I didn't think what you wrote was inflammatory and it's undeniable that Emacs has the largest mindshare in the Clojure world.

I haven't tried it, but for parallelisation it's sometimes worth starting from more "array-oriented" code, e.g. (defn max-diff [check-until] (let [val (map #(Math/sqrt %) (range 1 check-until))] (reduce max (map #(Math/abs (- %1 %2)) (map #(Math/pow % 2) val) (map #(* % %) val) On Fr
