NYC Clojure Users Group Meeting for Jan 28th - I reserved a bigger space!

I've reserved a larger space to accommodate 55 people (we were out of room). There will be desks in the front and rows of seats in the back so come a bit early if you want a desk. For more details, see the full listing: http://www.meetup.com/Clojure-NYC/calendar/12228936/ When: Thursday, January 2

[ANN] units.clj - unit conversion functions without repeating yourself

Hi, I created a library that provides unit conversion functions[1] for several common units and allows you to define new units conversions with a single equation. The library does a few interesting things automatically: First, if you define inches-to-feet, it will create feet-to-inches for you.

NullPointerException from #'> et al.

Re: NullPointerException from #'> et al.

What do you think should be the boolean result of (> nil 1)? Since the inequality functions only work with Numbers, and nil is not a Number. The only way to make that work would be to impute some default numerical value to nil, which would probably introduce more problems than it solved. On Jan

This is more java related but there is a java library and application ( http://futureboy.us/frinkdocs/) that provides a set of very powerful unit conversion tools. On Thu, Jan 14, 2010 at 10:49 AM, Scott Jaderholm wrote: > Hi, > > I created a library that provides unit conversion functions[1] fo

Compilation-aware code?

Some people have had issues with c.c.logging in that it looks for a suitable logging implementation at macro-expansion-time (by simply trying to import the necessary classes), which thus also occurs during AOT compilation; the down-side is that if the desired logging lib is not on the classpath dur

Timothy, Thanks for the suggestion. Creating a million keys within the same with-server is possible, without seeing the NoRouteToHostException. So, hitting with-server so many times in so short a time period is definitely a bad idea (duh). So, I think there is a problem with how my larger progra

StackOverflowError possible with seq ?

Is it possible that the Clojure core seq function can cause a stack overflow (since it calls itself)? Or is there some other manner in which misuse of a lazy seq could cause this? In the stack trace below, I'm seeing repeated calls to "seq" in clojure core, until the stack is blown. Thanks, Kyle

You might change the method-dumps definition to this: method-dumps (map (fn [i x] (str " " i ": " x)) (range 0 method-count) methods) It isn't more compact but I suppose it's more Clojure-y. On Jan 14, 6:49 pm, Raoul Duke wrote: > hi, > > i'm guessing there is a more Clojure-y and compact way t
