00:43	mdeboard	technomancy: I'm getting that darn "java.util.concurrent.RejectedExecutionException" again... swank 1.3.2
01:44	amalloy	mdeboard: what did you do to fix it last time? (also would you mind killing mdeboard_? he's vexing my tab completion)
02:00	amalloy	mdeboard: you're the one i was arguing with about github's clojure parser/highlighter, right? apparently they use pygment to color stuff
02:03	amalloy	from what i can tell, whoever wrote pygment's clojure plugin just gave the scheme plugin a mild facelift and a different list of keywords - there's some stuff that's definitely not right
05:33	shtutgart	Hi. How can I specify maximum value of y-axis in the Incanter chart? e.g. (bar-chart [:a :b :c] [10 20 30]) gives me Y values from 0 to 30, but I need maximum value of 100
05:36	Dranik	hi, shtutgart! do you remember the function wrap-codepage which you've shown me?
05:37	Dranik	doesn't it break CSS?
05:38	shtutgart	it shouldn't (unless your CSS files have a different encoding)
05:40	Dranik	yeah, it was in ascii...
05:40	Dranik	but how about the other types of files?
05:42	shtutgart	ah, yeah, it sets content-type to text/html, so you have to wrap only the handler which serves your pages
05:44	Dranik	yep :-)
05:46	Dranik	here is the best example of ho to deal with the utf8
05:46	Dranik	http://code.google.com/p/world-of-meme/source/browse/src/main/clojure/net/marigolda/templating_start.clj?spec=svn42b4a10a706bab53f89a0efb50610a50bfa8444a&r=42b4a10a706bab53f89a0efb50610a50bfa8444a
05:46	Dranik	see the function wrap-charset
05:56	shtutgart	yeah, it much more general. Interesting, why some similar thing doesn't included in compojure itself
05:59	Dranik	probably noone did a pullrequest or issue
05:59	Dranik	let me try...
06:00	Dranik	actually I don't know, probably it should be a ring middleware
06:02	shtutgart	ah, see https://github.com/mmcgrana/ring/commit/2b3f560e9d9c15a8da0ec626f0f10bf9c5014ff4
06:11	Dranik	shtutgart, dunno when it will be available for testing
06:11	Dranik	but I guess it should be so
06:11	Dranik	waiting for weavejester to talk to him about his commit :-)
06:59	rhebus	hello
07:00	fliebel	hi
07:00	rhebus	what's an idiomatic way of returning a map with the values modified by a function?
07:00	rhebus	I've got a few options but they don't feel right
07:01	rhebus	for example, (merge-with (fn [x y] (inc x)) my-map my-map) to apply inc to vals of my-map but it's horribly abusive
07:01	fliebel	rhebus: can you paste a few lines? Sounds to me like you want to do (fn foo [m] (assoc m :foo 2 :bar 3))
07:01	fliebel	hm
07:02	rhebus	no, i want to apply a fn to each val of a map
07:02	shtutgart	something with update-in
07:03	fliebel	what about (into {} (zipmap (keys m) (map inc (vals m))))
07:03	fliebel	&(let [m {:a 1 :b 2}] (into {} (zipmap (keys m) (map inc (vals m)))))
07:03	lazybot	⇒ {:b 3, :a 2}
07:03	shtutgart	rhebus: btw, we have a conversation about including function update (like (update {:a 1 :b 2} :a inc :b dec)) some days ago
07:04	shtutgart	but I forgot to post the suggestion on the google group
07:04	rhebus	those look better than what I had
07:05	rhebus	(map (fn [ [x y] ] [x (inc y) ]) my-map) was my next try, but that's a list of vectors, not a map
07:05	fliebel	rhebus: you can use (into {}) with that as well.
07:06	rhebus	so keys and vals are guaranteed to preserve respective order? that's kinda neat I guess
07:06	fliebel	zipmap is just a fancy way of avoid handling the key in the map.
07:06	fliebel	rhebus: yea, that's guaranteed as far as I know.
07:07	rhebus	wait, why do you need into {} with zipmap?
07:07	rhebus	&(let [m {:a 1 :b 2}] (zipmap (keys m) (map inc (vals m))))
07:07	lazybot	⇒ {:b 3, :a 2}
07:07	fliebel	rhebus: uh, yea, I'm to used to Python.
07:07	rhebus	:)
07:08	rhebus	thanks for your help, much appreciated
07:08	fliebel	In Python, zip just goes from [1 2 3] [4 5 6] to [1 4] [2 5] [3 6]
07:10	rhebus	I'm used to perl, where i'd probably copy-and-mutate
07:13	tomoj	(update {:a {:b 3 :c 4}} [:a :b] inc [:a :c] dec) too would be nice
07:13	tomoj	oh, can't have both
09:50	xom_approves	hi there
09:50	xom_approves	is there an idomatic pattern for this? http://pastebin.com/R6FEvtJF
09:50	xom_approves	i'm really new to clojure, btw :)
09:51	raek	xom_approves: (map extract xml-seq) I believe
09:52	xom_approves	hm
09:52	xom_approves	oh right the paste is simplified
09:52	raek	map is lazy, though
09:52	xom_approves	lazy is good here
09:53	raek	but otherwise the looping code looks good
09:53	xom_approves	basically i need a custom accumulation
09:53	xom_approves	ah okay
09:53	raek	reduce might be applicable too
09:54	xom_approves	god, yes so simple
09:54	xom_approves	thanks raek
09:54	raek	(reduce #(conj %1 (extract %2))) xml-seq)
09:54	raek	(reduce #(conj %1 (extract %2))) [] xml-seq)
09:56	xom_approves	(reduce #(merge %1 (extract %2)) {} xs) in my case
10:28	shtutgart	Hi. How can I specify maximum value of y-axis in the Incanter chart? e.g. (bar-chart [:a :b :c] [10 20 30]) gives me Y values from 0 to 30, but I need maximum value of 100
10:50	cmbntr_	account 0 off
11:38	shtutgart	,(.getMessage (Exception. "foo"))
11:38	clojurebot	"foo"
11:39	kephale	is there a way to establish symbol bindings for a let from a map? i.e. (let-map {:a 17} [b (inc a)] (inc b))
11:39	kephale	since let is a macro apply can't be used
11:40	shtutgart	kephale: if a map should be evaluated in runtime, then no, I think
11:41	shtutgart	Any ideas why I'm getting "java.lang.IllegalArgumentException: foo" on (.getMessage (IllegalArgumentException. "foo"))?
11:42	shtutgart	(of course actually there is more code)
11:44	shtutgart	(try (throw (IllegalArgumentException. "foo")) (catch Exception e (.getMessage e)))
11:44	shtutgart	,(try (throw (IllegalArgumentException. "foo")) (catch Exception e (.getMessage e)))
11:44	clojurebot	shtutgart: Cool story bro.
11:44	kephale	lol
11:45	shtutgart	eh... I'll better do it via private msgs
11:51	kephale	ah, push-thread-bindings
11:52	kephale	err with-bindings seems like the proper thing to use
11:53	shtutgart	but you've said you need locals?
12:00	kephale	well, i really just care about being able to establish bindings from a map, and update the map with new bindings in a sequential let-style
12:03	shtutgart	hm, probably I don't understand the whole thing, but why can't you use оыге здфшт ьфз,
12:03	shtutgart	sorry, I mean "why can't you use just plain map?"
12:04	shtutgart	Don't think that it's good to have a number of global vars for such purposes...
12:05	kephale	,(-> {'a 7} (assoc 'b 8))
12:05	clojurebot	{b 8, a 7}
12:05	kephale	but I would also like to be able to reference the map
12:06	kephale	to get something like:
12:06	kephale	,(-> {'a 7} (assoc 'b (inc a)))
12:06	clojurebot	java.lang.Exception: Unable to resolve symbol: a in this context
12:06	kephale	clearly that shouldnt work
12:08	shtutgart	,(let [{:keys [a b] :as m} {:a 1 :b 2}] (-> m (assoc :b (inc a))))
12:08	clojurebot	{:a 1, :b 2}
12:08	shtutgart	bad example, there should be (dec a) to see the difference :)
12:09	kephale	,(let [{:keys [a b] :as m} {:a 1 :b 2}] (-> m (assoc :c (inc a))))
12:09	clojurebot	{:c 2, :a 1, :b 2}
12:09	kephale	,(let [{:keys [a b] :as m} {:a 1 :b 2}] (-> m (assoc :c (inc a)) (assoc :d (inc c))))
12:09	clojurebot	java.lang.Exception: Unable to resolve symbol: c in this context
12:10	kephale	I need that ability as well
12:10	kephale	which I guess could be accomplished by wrapping an expression like that in a loop
12:11	shtutgart	yeah
12:11	kephale	cool, ty
12:11	shtutgart	but there also should be more elegant and sequntial, loop-free solution
12:14	kephale	well, if there is a way to pull the binding map out of a let
12:14	kephale	then
12:14	kephale	,(let [{:keys [a b] :as m} {:a 1 :b 2} c (inc a) d (inc c)] d)
12:14	clojurebot	3
12:14	kephale	does leverage the let
12:17	shtutgart	what about kind of ##(reduce (fn [m [k v]] (assoc m k (v m))) {:a 1} [[:b :a] [:c :b]])
12:17	lazybot	⇒ {:c 1, :b 1, :a 1}
12:20	shtutgart	or ##(reduce (fn [m [k f]] (assoc m k (f m))) {:a 1} [[:b #(-> % :a inc)]]), or some combination of the two
12:20	lazybot	⇒ {:b 2, :a 1}
13:24	Scorchin	leiningen q: should everything in :dev-dependencies and :dependencies go in :exclusions as well?
13:47	dekuderp	how does one verify a record type?
13:48	dekuderp	if I want to create a function with a conditional based on the record passed to it
14:44	mdeboard	technomancy: So I upgraded to swank-clojure 1.3.2, and the `lein run` dev server ran ok for a day or two, but now back to the "RejectedExecutionException" errors from before
14:44	mdeboard	I didn't change anything at all.
14:44	mdeboard	Only thing I did actually was to restart the virtualmachine in which I run ubuntu
15:05	fliebel	What do we think of Gremlin and Blueprints?
15:14	mdeboard	fliebel: Blueprints... the CSS framework?
15:14	fliebel	mdeboard: No, the graph db interface
15:19	dekuderp	when I get an error like this: Key must be integer [Thrown class java.lang.IllegalArgumentException], what kind of mistake should I be looking for?
15:20	dekuderp	https://gist.github.com/1086657
15:20	mdeboard	dekuderp: A traceback would be nice wouldn't it
15:20	dnolen_	first stack overflow core.logic question, fun, http://stackoverflow.com/questions/6713424/how-do-i-express-this-logic/6719627#6719627
15:21	fliebel	dnolen_: congrats, that's quite an accomplishment, but it does remind me of something cgrand said about moustache...
15:21	dnolen_	fliebel: ?
15:21	fliebel	dnolen_: He thought no one was using it because he never got questions about how it worked.
15:22	dekuderp	mdeboard: oh, now I see where the line numbers are
15:22	mdeboard	dekuderp: where
15:22	dnolen_	fliebel: if you're saying that think moustache is a lot easier to understand, I agree :)
15:22	fliebel	yea :D
15:22	mdeboard	orite
15:22	dekuderp	https://gist.github.com/1086660
15:23	dekuderp	I am so used to getting nice clojure errors with the offending line # at the top
15:23	Demosthenes	so i've heard the arguments from the CL people that "of course CL is used for commercial software", but they mean backend with a full lisp environment. racket? they have a handful, seems like web services. is anyone creating client software, like fat clients for windows and linux in clojure?
15:24	dnolen_	fliebel: it's a particular fun question tho, it's a tricky problem solved with very little code (tho I admit I had to think about it for a while)
15:28	dekuderp	I think my mistake is that I thought you could do ('[1 [2 3]] [1 0]) => 2
15:28	dekuderp	or I thought I saw someone use a trick like that to access a nested vector
15:30	dnolen_	,(get-in [1 [2 3]] [1 0])
15:33	clojurebot	2
15:33	dnolen_	dekuderp: ^
15:35	dekuderp	dnolen: thanks!
15:35	mdeboard	Demosthenes: I think most of the commercial production clojure products/interfaces are closed-source.
15:35	Demosthenes	mdeboard: i've picked up a few lisp dialects now, generally for unix, scripting, or backend processes. but if i need to deploy a short simple app toa windows client, my options REALLY shrink.
15:36	Demosthenes	sbcl was great (awesome debugging!), racket's quick and simple, but neither seems suitable for me to create a short app to deploy to non-IT clients.
15:36	mdeboard	Demosthenes: Were you the guy asking about clj msis?
15:36	Demosthenes	i mean really, i need http/https, TLS/SSL, and a basic gui... :P
15:36	Demosthenes	nope
15:37	dekuderp	what can I use to find out what kind of record a var is? I know (instance? record-name var) but I want something like (record-type? var) that returns record-name
15:38	dnolen_	,(type 1)
15:38	clojurebot	java.lang.Integer
15:38	dnolen_	dekuderp: ^
15:38	bendlas`	hi
15:39	dekuderp	dnolen: thanks again!
15:39	bendlas`	does somebody know, if clutch is compatible with couchdb 0.10?
15:40	bendlas`	in particular, if you can use the clutch view server with 0.10
15:45	mdeboard	,(min-key - 1 2 3)
15:45	clojurebot	3
15:45	mdeboard	,(key 1 2 3)
15:45	clojurebot	java.lang.IllegalArgumentException: Wrong number of args (3) passed to: core$key
15:46	dekuderp	okay here is my code: https://gist.github.com/1086690 and here is the output I'm getting: https://gist.github.com/1086692
15:47	dekuderp	I really don't get how type is returning nothing or java.lang.Class instead of the records I use
15:50	dekuderp	oh I fixed it, I was using (repeat 9 Road) instead of (repeat 9 (Road.))
15:50	dekuderp	stupid me:P
15:52	mdeboard	dekuderp: tsk tsk
15:54	mdeboard	dekuderp: I kid, what you've written there is more than I could do :(
16:27	amalloy	dekuderp: advice: don't use records unless you have a strong performance need
16:28	amalloy	i filled my first program with records, because i "wanted" classes. but records are (mostly) a higher-performance, lower-convenience version of hashmaps. see http://cemerick.com/2011/07/05/flowchart-for-choosing-the-right-clojure-type-definition-form/ for a handy little flowchart about when to use what
16:28	dekuderp	amalloy: I was going to use structmaps but the clojure data structure page said I should go with records ( http://clojure.org/data_structures )
16:29	amalloy	yes, structmaps are deprecated
16:29	amalloy	but take a look at cemerick's flowchart. from what i know of your application, you'll wind up at "use a regular map"
16:30	dekuderp	amalloy: thank you, that flow-chart is awesome
16:37	amalloy	dekuderp: it's good policy, btw, to define a function like (make-building args) so that you can switch from hashmaps to records whenever you need to, without needing the client code to change: you can just change the implementation of make-building
16:42	dekuderp	amalloy: so you're saying try to keep the implementation from affecting the design right?
16:42	amalloy	wellll, i would have used the word API, not design
16:43	dekuderp	lol yeah my terminology is pretty bad
17:09	seancorfield	clojure.java.jdbc still uses structmaps (because clojure.contrib.sql did) - i guess that needs to be fixed...
17:10	seancorfield	stuart sierra made a comment about it early on when i took over c.j.j and at the time i wasn't sure what he meant but i opened a ticket http://dev.clojure.org/jira/browse/JDBC-3
17:49	Kenjin	hello
17:57	Kenjin	I'm having trouble setting up clojure with emacs+slime. M-x clojure-jack-in just hangs with "Starting swank server..."
18:02	jonabbey	is emacs in the right directory?
18:02	jonabbey	i.e., try loading the project.clj file from lein and then run the M-x clojure-jack-in from that buffer
18:14	Kenjin	jonabbey: how do I load project.clj from lein
18:21	Kenjin	jonabbey: I open project.clj in emacs and run M-x clojure-jack-in and its seems slime.el is dumped in the swank buffer
18:27	amalloy	Kenjin: you can narrow down the problem by trying `lein swank` from the command line, followed by M-x slime-connect
18:27	amalloy	if either of those steps succeeds, the problem is probably with the other step (if they both succeed, something's wrong with jack-in)
18:27	Kenjin	On the swank-clojure readme it says "From inside a project, invoke M-x clojure-jack-in". What does "from inside a project" mean?
18:27	Kenjin	amalloy: thank you. I'll try that
18:41	raek	Kenjin: from any file somewhere in the project tree (even outside src/ works)
18:41	dekuderp	I can use :type as a key in a map, right? or is it some clojure keyword?
18:41	Kenjin	raek: understood. thank you
18:42	raek	dekuderp: the keyword with the name ":type" is not special in any way
18:43	dekuderp	raek: thanks
18:44	amalloy	raek: it's a little special, isn't it? ##(doc type) looks it up in the metadata
18:44	lazybot	⇒ "([x]); Returns the :type metadata of x, or its Class if none"
18:46	amalloy	not that dekuderp cares about that
18:48	Raynes	amalloy: Yeah, the keyword itself is just a normal keyboard. It just happens to be the keyword that type looks for in metadata.
18:49	Raynes	The name of defn includes the letter 'd'. Doesn't make 'd' special.
18:53	Kenjin	is the issue with slime and autodoc still unresolved?
19:00	dekuderp	okay here is my new code: https://gist.github.com/1086893 and the output: https://gist.github.com/1086896
19:00	dekuderp	I have no clue how I'm screwing this up so badly
19:32	mdeboard	Why does this work ok: http://p.mattdeboard.net/mcount_good.html but this does not: http://p.mattdeboard.net/mycount_bad.html (note the reversal of the args)
19:39	amalloy	mdeboard: your pastes give me an nginx timeout error. try gisting instead?
19:40	mdeboard	improperly configured apache :(
19:40	mdeboard	try again
19:41	mdeboard	had to reboot servar :(
19:41	amalloy	mdeboard: you swapped args to mycount but not to recur
19:41	mdeboard	oh, gosh.
19:45	dekuderp	okay, I finally got my code working: https://gist.github.com/1086926
19:46	dekuderp	I tried cleaning it up and tried to use the paradigms you guys talk about, but if anyone could suggest any way I could make it simpler I'd really appreciate it
19:48	amalloy	dekuderp: it's more common to use :building for type rather than "building". keywords are pretty good at enum-like things
19:49	amalloy	i'd delete the five-argument version of add-buildings and make it a (loop ... (recur)) in the three-argument version
19:53	mdeboard	awesome solution to 4clj #25 imo
19:53	mdeboard	#(->> % (filter odd?))
19:54	amalloy	mdeboard: isn't that just #(filter odd? %)?
19:54	mdeboard	oh, yeah probably. I chose ->> at first because I misread the problem at first.. thought there was some follow-on operation I had to do
19:55	mdeboard	mostly just happy I properly used ->>
19:55	amalloy	smile
19:55	amalloy	it's an exciting thing to use
19:55	dekuderp	amalloy: I don't understand your first point. So I would have a key (:building) that matches to nothing, and then rewrite to just check if that key exists?
19:55	amalloy	dekuderp: nono, :type is fine
19:55	amalloy	for example, (defn make-road [] {:type :road})
19:56	dekuderp	and then I would have (= :road (:type road-obj)), right?
19:56	amalloy	yeah
19:56	dekuderp	okay, now I get it
19:57	amalloy	dekuderp: here's a skin-deep rewrite of add-buildings: https://gist.github.com/1086948
20:00	amalloy	and (defn world-obj-to-str [world-obj] ({:building "B", :road "r", :firefighter "F"} (:type world-obj))) has a lot less boilerplate
20:03	dekuderp	amalloy: in your gist you used let to define new-world, in clojure is it normal to bind a var to let if it's referenced more than once?
20:03	amalloy	that's exactly what let is for
20:04	dekuderp	for some reason I thought it was overkill to use if I wasn't defining more than 2 variables...
20:04	amalloy	i mean, you can use it for things that are only referenced once; it's often more readable that way because you can split things up
20:04	amalloy	but reuse is the main goal
20:05	dekuderp	amalloy: thanks again for all this useful info
20:05	amalloy	dekuderp: nah, overkill is writing the same four lines of code twice to avoid a let :)
20:07	dekuderp	lol well now I know that's cool to try and minimize repeating code
20:08	dekuderp	I'm just so used to java and constantly repeating myself I guess
20:10	amalloy	heh
20:10	amalloy	dekuderp: well, java has local variables too
20:10	amalloy	a way you can really outdistance java is by defining local functions to avoid repeating sections of code
20:14	mdeboard	4clj #23 is a SOB. #(map - (sort (map - %))) works for all the examples except the last one :(
20:14	mdeboard	http://4clojure.com/problem/23
20:15	amalloy	dekuderp: https://github.com/flatland/useful/blob/develop/src/useful/fn.clj#L28 is an example of that sort of thing. don't worry about understanding the whole function - it's pretty abstract and a little messy. but see how i'm defining a local function `call` to avoid rewriting that code
20:16	amalloy	mdeboard: isn't this problem asking you to reverse a sequence, not sort it in reverse order?
20:16	mdeboard	Yeah. :P I was being cheap.
20:16	amalloy	chuckle
20:16	mdeboard	didn't even look at the third one.
20:17	amalloy	if you wanted to do it that way, btw, ##(sort-by - [1 2 3 4 5]) is simpler
20:17	lazybot	⇒ (5 4 3 2 1)
20:17	mdeboard	ahh
20:17	mdeboard	was wondeirng how that worked
20:17	amalloy	and is equivalent to what you were doing, i think
20:17	mdeboard	there you have it
20:17	mdeboard	yeah
20:17	mdeboard	definitely is
20:18	mdeboard	I guess just running "shuffle" until they appear in the proper order would be cheap too
20:19	mdeboard	(a joke)
20:20	amalloy	$google bogosort
20:20	lazybot	[Bogosort - Wikipedia, the free encyclopedia] http://en.wikipedia.org/wiki/Bogosort
20:21	mdeboard	lol
20:21	mdeboard	Yeah, tha
20:21	amalloy	mdeboard: quantum bogosort is a nice refinement of tha algorithm, getting it down to O(n)
20:22	mdeboard	lolirl
20:22	mdeboard	yeah I guess all possible permutations would exist simultaneously
20:39	mdeboard	amalloy: Explain:
20:39	mdeboard	,(into '() [1 2 3 4 5])
20:39	clojurebot	(5 4 3 2 1)
20:39	mdeboard	why is that reversed?
20:39	amalloy	&(conj '(1 2 3) 4)
20:39	lazybot	⇒ (4 1 2 3)
20:40	mdeboard	Ohhh
20:40	amalloy	lists (and seqs in general) conj on the left
20:40	mdeboard	oh righ tlisp reads right ot left
20:40	amalloy	uhhh
20:41	amalloy	i don't understand that explanation
20:43	mdeboard	Don't fight it, it will just make this more difficult
20:50	amalloy	&(reduce (partial list 'conj) () [1 2 3 4 5])
20:50	lazybot	⇒ (conj (conj (conj (conj (conj () 1) 2) 3) 4) 5)
20:51	amalloy	mdeboard: that's what into is doing, under the hood. and because ##(conj '(1) 2) is '(2 1), the whole thing balloons out to the left
20:51	lazybot	⇒ (2 1)
20:51	mdeboard	ahh
21:41	tomoj	I just met the expression problem face to face for the first time I think
22:02	mdeboard	amalloy: In problems.clj for 4clj what is the ":_id" keyword? It's all ove rthe place. Is it a function? Shortcut for a query?
22:02	amalloy	mdeboard: mongodb's unique identifier. each document you store gets a new _id
22:03	mdeboard	specifically "(apply min-key :_id unsolved)"
22:03	amalloy	we (wrongly imo) hijack that to be the problem's numeric id
22:03	mdeboard	just get the smallest id among unsolved
22:03	amalloy	so http://4clojure.com/problem/23 has its data stored in mongo with an _id of 23
22:04	amalloy	anyway, (apply min-key :_id unsolved) isn't exactly what you said. it returns the problem with the smallest id, not the smallest id
22:04	mdeboard	ah ok
22:05	mdeboard	yeah that makes sense
22:05	amalloy	&(let [problems [{:_id 4 :data "TEST", :_id 9 :data "SAMPLE"}]], (apply min-key :_id problems))
22:05	lazybot	java.lang.IllegalArgumentException: Duplicate key: :_id
22:05	mdeboard	kind of like an ORM in practice
22:05	amalloy	&(let [problems [{:_id 4 :data "TEST"} {:_id 9 :data "SAMPLE"}]], (apply min-key :_id problems))
22:05	lazybot	⇒ {:_id 4, :data "TEST"}
22:06	amalloy	not really. i mean, i don't use any ORMs, but my understanding is that they're for mapping the application level notion of objects onto the table-oriented database
22:06	amalloy	mongodb is a document/object centric db, so we just put maps in and get maps out
22:10	mdeboard	amalloy: http://p.mattdeboard.net/nextunsolved.html would this work to only retrieve problems whose id is greater than the last problem solved? Biggest annoyance with 4clj righ tnow
22:10	mdeboard	for me
22:10	mdeboard	I can't run lein run to test it out myself unfortunately
22:11	mdeboard	getitng those execution exceptions
22:11	mdeboard	s/test it out/play with it
22:12	amalloy	mdeboard: care to step into #4clojure?
22:12	mdeboard	sure
