00:37	Frozenlock	hmm... clojars no longer accepts public keys? When I go in 'profile' I can only update my email and password :-/
00:59	Frozenlock	Seems it's no longer required.
05:23	narwhal01	hi guys
05:26	narwhal01	what is the best way to do this: if i have list of hashes as [{:k "a"} {:k "b"} {:k "c"} {:k "m"} {:k "c"} {:k "b"}], what is the best way to select consecutive hashes based on one schema "abc" , or "mc", or whatever "abc" refer all hashes with :k equal a then b then c consecutively
05:27	narwhal01	the provided schema should be generic
05:27	narwhal01	is there a good solution of this?
05:30	ridcully	ztellman/automat has a similar example in its readme
05:33	narwhal01	ridcully, what exactly? in the page?
05:33	narwhal01	https://github.com/ztellman/automat
05:34	ridcully	the "short example"
06:17	narwhal01	ridcully, can you help me out to use automat to apply on my example?
06:30	ridcully	narwhal01: most likely not. i only remembered it from reading some time ago
06:30	ridcully	,(let [m [{:k "a"} {:k "b"} {:k "c"} {:k "m"} {:k "c"} {:k "b"}] s "abc" l (count s)] (filter #(= s (apply str (map :k %))) (partition l 1 m)))
06:31	clojurebot	(({:k "a"} {:k "b"} {:k "c"}))
06:57	narwhal01	,(let [m [{:k "aa"} {:k "bb"} {:k "cc"} {:k "mm"} {:k "cc"} {:k "bb"}] s "aabbcc" l (count s)] (filter #(= s (apply str (map :k %))) (partition l 1 m)))
06:57	clojurebot	()
07:41	l1x	hey guys, is there a way to do a (def something JavaClass.) and (.method1 something) and than (.metehod2 something) in clojure somehow nicely? I know of the -> macro but it does not apply here because the methods do not return the changed object
07:42	opqdonut	doto
07:42	luma	(doto (JavaClass.) .method1 .method2)
08:02	Empperi	,(doto (java.util.HashMap.) (.put "foo" "bar") (.put "bar" "foobar"))
08:02	clojurebot	{"foo" "bar", "bar" "foobar"}
08:02	Empperi	a more complete example
08:21	ashnur	any good talk/video on persistend data structures, how they are implemented? something that's not a MIT lecture :D
08:22	l1x	opqdonut & luma thx! Empperi too :)
08:27	mokuso	what's wrong with MIT lectures? xD
08:27	ashnur	nothing in particular, but i just want to show someone a link where they can get a feel on how this works
08:31	ashnur	i remember seeing a video where someone explained this in a few minutes, why it works and how it works
08:59	miguelsm	ashnur: https://youtu.be/mS264h8KGwk?t=8m40s
12:17	jeaye	https://news.ycombinator.com/item?id=11240004 written in clojure/script
12:46	sdegutis	I wrote a blog post for you guys http://sdegutis.github.io/2016-03-04/clojure-naming-best-practices/
12:55	mavbozo	sdegutis, thank you
12:56	sdegutis	mavbozo: I truly hope you find it helpful, because I spent like 20 minutes trying to get that CSS to not be completely awful.
12:56	MJB47	what about :use :only
12:59	sdegutis	MJB47: That's the exact same thing as (:require :refer) and has all the same drawbacks.
13:00	amalloy	sdegutis: missiona ccomplished: "not completely awful" is how i would describe that CSS
13:00	sdegutis	amalloy: yesssss
13:06	sdegutis	Is it possible using some function in clojure.core to create a function that ignores its parameter(s) and returns a constant value, much like (constantly) but allowing argument(s) to be passed?
13:09	tolstoy	(fn [& args] 42)?
13:11	justin_smith	sdegutis: constantly
13:11	justin_smith	,((constantly 42) :a :b :c :d)
13:11	clojurebot	42
13:11	justin_smith	:b8
13:11	ddellacosta	sdegutis: I'm not entirely clear what you're asking for--if you want to return the argument passed, the constantly; if you want the arg passed in, then identity is it
13:11	ddellacosta	then* constantly
13:11	ddellacosta	reverse what I said, d'oh
13:14	sdegutis	Huh. Wow, yeah, I was misusing constantly.
13:14	sdegutis	I was stupidly doing something like (#(constantly 1) 2 3) or something.
13:14	sdegutis	Turns out constantly is what I always wanted.
13:15	sdegutis	Thanks everyone.
13:17	justin_smith	sdegutis: alternatively you could do ((#(constantly 1)) 2 3) but that would be silly
13:18	sdegutis	justin_smith: Yes. Yes it would.
13:39	sdegutis	Hi.
13:58	sdegutis	Is there a shortcut for this pattern? (->> (for [x xs] (str (f x))) (apply str))
13:59	sdegutis	I find it very ugly and I hate its stupid face. Thanks in advance.
14:01	rhg135	(apply str (map f xs)) I think
14:09	sdegutis	rhg135: Hmm sorry, I should have done dot-dot-dot instead.
14:09	sdegutis	Is there a shortcut for this pattern? (->> (for [x xs] (str ...)) (apply str))
14:10	rhg135	(apply str (map (comp str ...) xs)
14:11	amalloy	sdegutis: i think the shortcut is to just omit the inner str call
14:11	sdegutis	amalloy: Hmm.
14:12	rhg135	that
14:12	amalloy	since (str 1 2) is the same as (str (str 1) (str 2))
14:12	sdegutis	I guess I was looking for something like (for-str [x xs] ...)
14:13	sdegutis	I'd like to create a giant string based on transforming some Clojure data structures, and having several (apply str) in the middle of other (apply str) feels clunky.
14:13	sdegutis	One alternative is to use a more "proper" templating library, like clostache.
14:13	sdegutis	But I feel like there's got to be something that's more friendly to Clojure transformations, considering Clojure already is its own kind of DSL as opposed to moustache.
14:14	sdegutis	Rather than {{#foo}}{{bar}}{{/foo}} I'd like to have (for [foo foos] (:bar foo)) or something.
14:14	sdegutis	But with even one level of nesting, that gets real ugly real quick.
14:14	amalloy	sdegutis: i mean, you could like...omit all of the apply str calls, and return a list of things you want the outermost str to apply to
14:14	amalloy	just make sure not to create the nesting
14:15	sdegutis	Or maybe use mapcat.
14:15	sdegutis	So I guess I want something like for but with mapcat? Hmm.
14:15	sdegutis	Which for already kind of has built-in.
14:15	amalloy	for is already like for but with mapcat
14:15	sdegutis	Right.
14:16	sdegutis	If I return a vector, it flattens it for me.
14:16	sdegutis	Wait, that doesn't make sense.
14:16	sdegutis	,(for [a (rest (range 5))] [a a a])
14:17	clojurebot	([1 1 1] [2 2 2] [3 3 3] [4 4 4])
14:17	sdegutis	Hmm. What's that behavior I'm thinking of?
14:17	sdegutis	Is it not in (for)?
14:19	justin_smith	,(for [a (rest (range 5)) b [a a a]] b)
14:19	clojurebot	(1 1 1 2 2 ...)
14:20	amalloy	sdegutis: (for [x xs, r (f x)] r) is the same as (mapcat f xs)
14:20	amalloy	in that simple scenario of course it's nicer to use mapcat, but if you're doing anything more involved for can be pretty good
14:20	sdegutis	I see.
14:21	sdegutis	justin_smith: But I vaguely remember some weird behavior where some type of mapping/transforming function treats a returned list as a special thing and "flattens" the results by removing that list, making you have to do something like [[x]] if you really wanted to return [x].
14:22	TMA	,(for [a (rest (range 5))] (let [r [a a a]] r))
14:22	clojurebot	([1 1 1] [2 2 2] [3 3 3] [4 4 4])
14:22	TMA	,(for [a (rest (range 5)) b [a a a]] [b])
14:22	clojurebot	([1] [1] [1] [2] [2] ...)
14:23	amalloy	sdegutis: i can't think of any commonly-used functions that behave that way
14:24	TMA	mapcat is a wrong simile -- (for [v1 ... v2 ...] ...) is a nested loop producing one element of the resulting sequence per iteration
14:25	TMA	,(for [a (range 5) b (range a)] b)
14:25	clojurebot	(0 0 1 0 1 ...)
14:26	sdegutis	I'm sure I'm not crazy.. what could this mysterious function be?
14:26	TMA	,(for [a (rest (range 5)) b (range a)] b)
14:26	clojurebot	(0 0 1 0 1 ...)
14:27	sdegutis	The more I think about it, the more I think it was mapcat.
14:28	sdegutis	No wait, that can't be it. That's expected, whereas this was unexpected.
14:30	amalloy	TMA: are you saying that mapcat is a bad way to explain what for is doing?
14:31	TMA	amalloy: yes. #'for can be explained via mapcat, but the explanation using mapcat is needlesly complex and not general enough
14:35	TMA	first: (for [x xs] form) is (map (fn [x] form) xs); second: (for [x xs y ys ...] form is (apply concat (for [x xs] (for [y ys ...] form))) third: reorder the resulting form to use mapcat
14:36	sdegutis	Okay just searched the stdlib, nothing seems like what I'm thinking of.
14:36	sdegutis	Maybe I dreamed it up?
14:36	amalloy	cfleming: are you around? i can't figure out how to activate my cursive license. enabling cursive and restarting cursive just causes it to be re-disabled, rather than popping up the "show me your papers" menu i would hope for
14:37	amalloy	er, restarting intellij, not cursive, of course
14:38	amalloy	cfleming: well, never mind. just uninstalled cursive entirely, then reinstalled it; then did that a second time, and now it's asking for a license again
14:38	ridcully	have you tried turning it off and on again?
14:38	amalloy	not enough times, it seems
14:39	ridcully	in that case the advice from beavis and butthead applies: have you tried to set it on fire?
14:50	sdegutis	Two more blog posts for your reading pleasure: http://sdegutis.github.io/2016-03-07/simple-clojure-render-function/ and http://sdegutis.github.io/2016-03-07/simple-clojure-md5-function/
14:54	wink	sdegutis: could be parametrized even easier: https://github.com/winks/multiplex/blob/599a87b27dfdb937c519e0b9a2c1f251e998237f/src/multiplex/util.clj#L170
14:55	sdegutis	wink: hmm, I want to believe, but only TimMc and justin_smith and amalloy understood how the function on my blog works, so..
14:56	wink	yours has more format magic :P
15:02	sdegutis	Yay!
15:03	wink	sdegutis: may I suggest a link back to / - because the explanation that all the posts are indeed at the bottom is only written there :P
15:03	sdegutis	wink: Maybe just a header on that posts list will suffice.
15:03	sdegutis	"All posts, newest to oldest."
15:03	wink	plus only some of your footers link to github. but I like the colorscheme :P
15:05	amalloy	sdegutis: (format "" (name k))? what in the world?
15:09	TimMc	sdegutis: You've got some bug in your blog software, your variable reference syntax is being eaten.
15:16	wink	unescaped {? :P
15:17	sdegutis	amalloy: um, cuz of this
15:17	sdegutis	,(format "{{%s}}" :foo)
15:17	clojurebot	"{{:foo}}"
15:17	sdegutis	Oh yeah, wow, you're right TimMc and wink.
15:19	sdegutis	fricken Jekyll
15:21	sdegutis	ok fixed sorry bout that
15:23	TimMc	sdegutis: It's almost as if rendering and templating are hard and should not be oversimplified.
15:24	sdegutis	TimMc: oh?
15:24	TimMc	Which is to say: Careful with that "don’t need any escaping behavior or special logic".
15:24	sdegutis	TimMc: there's a time and place for everything
15:25	sdegutis	TimMc: sometimes escaping is not a need
15:25	TimMc	It never is, at the beginning.
15:25	TimMc	And that's how you get in trouble.
15:25	sdegutis	TimMc: i like your style
15:25	TimMc	me too
15:30	sdegutis	TimMc: +1
15:40	sdegutis	Hi.
15:40	sdegutis	wink: better?
15:42	wink	TimMc: to be fair it is kinda meta to blog about it with the same syntax that gets eaten by the blog software :P
15:42	wink	sdegutis: looks good
15:42	Shadizzle	hiredman: I was told that I should consult with you about getting clojurebot to log into #clojure-beginners. Not a big deal obviously, but I think it would nice if there's no significant reason for him not to be logged into that channel. I'm new to clojure and this channel in any case.
15:42	TimMc	wink: I think there's a problem with your md-hash...
15:42	wink	TimMc: it passed my tests so far
15:43	wink	but the other version with UTF-8 intrigued me :P
15:43	wink	maybe time for MOAR TESTS
15:43	hiredman	Shadizzle: I'll see what I can do
15:45	hiredman	I think clojurebot would respone to a irc invite, but freenode only lets ops do that
15:45	Shadizzle	hiredman: Cheers, thank you.
15:45	TimMc	wink: Try it with "Hello, world."
15:46	wink	nice, long string :P
15:46	wink	it's missing a leading 0
15:46	TimMc	yup
15:46	wink	works with "hello" for example
15:46	wink	thanks.
15:47	wink	I still prefer the parametrization
15:48	sdegutis	wink: no he meant the solution itself was dangerous since it discounted the importance of escaping
15:48	sdegutis	wink: so he hates my (defn (render s m) ...) function
15:48	sdegutis	validly, of course
15:48	wink	sdegutis: well, it's never "easy"
15:48	sdegutis	agreed, life is hard
15:48	wink	but one can live without a library
15:48	wink	TimMc: funny thing, I'm not even using the code :)
15:49	sdegutis	wink: btw regarding your md5 thing, i remember our version failed some test-cases where the first number was "1" or somtehing like that, i forget what exactly
15:53	sdegutis	Ahh yes http://clojure-log.n01se.net/date/2015-12-15.html
15:53	TimMc	haha
15:53	sdegutis	"TimMc: you'll be receiving our bill in 2-3 business days" crap I never received that
15:53	sdegutis	oh well, the quarter passed so im in the clear now
15:53	TimMc	well now there's interest on it
15:54	sdegutis	no thats not how it works. if you forget to bill past a certain date, its free.
15:55	AndreasO	Hello!
15:58	sdegutis	Hello!
16:00	sdegutis	I wish I could search #clojure logs (via http://clojure-log.n01se.net/) for "[[" because I'm sure that would turn up that mysterious function I'm thinking of.
16:03	TimMc	sdegutis: Who posted it?
16:04	sdegutis	me probably
16:04	AndreasO	A seesaw question. How do I address the root widget ? I'm using config! with select to change a canvas .
16:08	sdegutis	Is Seesaw still in active development?
16:10	AndreasO	sdegutis: last change was 20 days ago
16:10	sdegutis	Cool.
16:13	neoncontrails	You made it, AndreasO. :-)
16:13	AndreasO	neoncontrails: ?
16:14	neoncontrails	We were just chatting on the facebook group
16:14	AndreasO	Ahh
16:15	audrius	what is the URL for facebook goup?
16:15	AndreasO	https://www.facebook.com/groups/clojure/
16:16	audrius	dank
16:18	AndreasO	audrius: varsegod!
16:19	AndreasO	neoncontrails: so what now?
16:20	neoncontrails	¯\_(ツ)_/¯
16:20	AndreasO	22:04 AndreasO A seesaw question. How do I address the root widget ? I'm using config! with select to change a canvas .
16:20	TimMc	sdegutis: I can try my logs of this room, which are about 140 MB uncompressed.
16:20	sdegutis	wow
16:20	sdegutis	TimMc: wanna just send them to me?
16:20	TimMc	ha
16:20	sdegutis	TimMc: dont trouble yourself over searching for it, its mostly pointless
16:20	TimMc	I'd have to think about that, but maybe.
16:20	sdegutis	TimMc: but thanks
16:21	neoncontrails	AndreasO: answers sometimes come in an asynchronous fashion
16:22	TimMc	sdegutis: Too much chaff for "[["
16:22	amalloy	fwiw my personal #clojure logs, a paltry 54MB, have 2008 instances of [[
16:22	AndreasO	How can I find out if an answer has come?
16:22	sdegutis	TimMc: thought so
16:23	sdegutis	amalloy: when did you start keeping those logs? since about 2008?
16:23	neoncontrails	AndreasO: But in general posting a pastebin or some sort of live REPL of the issue is a good idea. Highly conducive to receiving help
16:24	amalloy	hm, i actually only have logs on this computer going back to 2014
16:24	amalloy	http://malloys.org/~akm/sdegutis.html -- lines matching /sdegutis.*\[\[/
16:25	TimMc	Mine start in 2011, but I'm sure there are gaps near the beginning.
16:25	sdegutis	amalloy: oh wow smart idea
16:26	sdegutis	haha! oh man. i was just about to say "look! the last line is the one i was looking for!"
16:26	amalloy	i should have logs going back to like 2010. i wonder where they went
16:26	sdegutis	but yeah, i cant find it
16:26	sdegutis	and it was definitely since 2014
16:27	AndreasO	neoncontrails: strange thing irc, like standing in a crowded room speaking and hoping for someone to respond.
16:27	sdegutis	thanks anyway amalloy and TimMc
16:28	amalloy	AndreasO: indeed. you probably just want to repeat your question every hour or so and hope someone who knows seesaw happens by. or you could ask on stackoverflow
16:28	neoncontrails	AndreasO: third-party libraries = smaller user community = fewer people may be able to help you
16:28	TimMc	AndreasO: Can be like that, yeah. More like a room of animated mannequins, and you're never sure which ones are "alive" at the moment. :-P
16:29	ridcully	if some java api takes varargs (e.g. void something(Class x, Something... ss)), am i right to assume, that i have to provide the `ss` there (e.g. with into-array) while java itself seems to allow for nothing?
16:29	TimMc	AndreasO: More helpfully: It's best to wait until a lull in the conversation to ask your question, otherwise existing conversations will bury it.
16:29	amalloy	ridcully: yes
16:30	AndreasO	TimMc: sounds like politics!
16:30	ridcully	amalloy: thanks. that seemed to be the only thing to make it compile, but i hoped for something shorter
16:30	TimMc	heh
16:30	amalloy	TimMc: i dunno if i agree with that. i just ask questions whenever i feel like it
16:30	TimMc	ridcully: Yeah, needs to be an array, specifically.
16:30	amalloy	which admittedly is rarely these days
16:30	TimMc	It depends on the question, though.
16:31	justin_smith	ridcully: it shouldn't be hard to make a macro that handles it nicely
16:33	ridcully	i was just baffled by the error. i am not that keen on java itself, when it comes to things like this. this is just fooling around with pac4j via ratpack via catacumba.
16:33	AndreasO	A seesaw question. How do I address the root widget ? I'm using config! with select to change a canvas .
16:33	TimMc	ridcully: (whoops, just saw that you mentioned into-array)
16:33	amalloy	i don't think a macro would make this any nicer
16:34	ridcully	so once it works, i will isolate it in some ns and hope they will never introduce breaking changes in a x.x.n release again...
16:34	amalloy	(.foo a b (into-array MyObj [])) vs...what? (no-args MyObj foo a b)?
16:34	justin_smith	amalloy: I was thinking something like a marker keyword :& and automatically putting everything after that into an array
16:35	amalloy	ridcully: what are you talking about re breaking changes?
16:35	amalloy	the varargs syntax was introduced in 1.5.0, breaking no existing code, and hasn't changed since then
16:35	ridcully	amalloy: this was a rant about pac4j - not java
16:36	amalloy	ah. they added an optional vararg param to an existing function, huh? that's an interesting change
16:37	spuz	if i want to create a fixed length array of booleans for use of random access (i.e. using nth) should I use a vector or a Java array/
16:37	spuz	?
16:37	amalloy	it doesn't break any existing java source, and they could arrange for it not to break any compiled java code either
16:38	amalloy	so i find it hard to blame them for introducing that; it's not their fault you're using some dumb language that breaks when they make a change that's forward-compatible in java
16:38	ridcully	amalloy: i am not even sure. the breaking change with classes was in 1.7.0 to 1.7.1; i had that simmering for a month or so now ratpack-pac4j adopted to that change and they introduced the varargs version. i have not looked into the details...
16:49	TimMc	spuz: Whatever your heart desires, but... vectors will probably be easier.
16:50	spuz	TimMc, well arrays seem easier to create, there is a boolean-array function. How would I create a vector of 100 false values?
16:50	AndreasO	Any seesaw gurus here?
16:53	TimMc	,(vec (repeat 100 false))
16:53	clojurebot	[false false false false false ...]
16:53	TimMc	spuz: ^
16:53	amalloy	AndreasO: better to just ask your real question, on irc, even if you don't know who will answer it. nobody knows if they count as a "guru" enough to answer your question, or wants to agree to help with a problem of unknown size
16:53	amalloy	TimMc: not that i disagree with your advice, our ancestors would be rolling in our graves if they knew how much space we use to store 100 bits
16:54	TimMc	AndreasO: The answer is probably "no, not right now". Maybe try tomorrow or at a different time of day, and not repeatedly in close succession.
16:54	TimMc	amalloy: Yeah, I winced a little writing that. :-(
16:54	TimMc	but I'm not going to tell spuz to use a bitset or something
16:55	AndreasO	TimMc: okay, need to sleep anyway. Got work tomorrow.
16:55	spuz	well BitSet makes the most sense for this application
16:55	spuz	it's just a prime sieve
16:55	TimMc	Oh hah, maybe you should use that then. :-)
16:55	spuz	but I guess I want to do it in the most 'clojure' way
16:55	TimMc	Be aware that it's mutable, tho.
16:55	amalloy	spuz: clojure favors practicality
16:56	spuz	amalloy, well practically I would use Java
16:56	spuz	that won't teach me new things though :)
17:01	sdegutis	Hi.
17:03	rcassidy	Hi!
17:05	audrius	sdegutis, Sigitas? :)
17:06	sdegutis	audrius: I am unsure of your meaning, friend.
17:06	sdegutis	rcassidy: hi!
17:07	audrius	sdegutis, I thought I found some person on IRC. newer mind it is not You then...
17:08	sdegutis	Sorry.
17:08	sdegutis	audrius: I mean, I /am/ me, for sure. I'm just not, who you thought I was? I guess?
17:08	audrius	well obviously :D
17:08	sdegutis	Hello! I am new to Clojure. How can format java Date using "YYYY-MM" please.
17:09	sdegutis	I may use Clojure 8 and Java 8. Thanks in advance regards.
17:09	sdegutis	This is NOT homework please note.
17:13	uris77	@sdegutis look at the clj-time library
17:15	sdegutis	Thanks uris77.
17:15	sdegutis	I will convert my Date to LocalDateTime using ZoneId, and then format it with DateTimeFormatter.
17:24	sdegutis	If you have a running app via `lein repl` and then do `lein clean` and `lein uberjar`, does that ruin the running app and/or result in a corrupted uberjar?
17:38	sdegutis	Looks like it corrupts the running copy only, and the generated uberjar works fine.
17:41	Mordus	Anyone know of a way to convert datascript Entities to maps? Datascript Entities are map-like, but they don't seem to be seqable. I'm using (d/touch (d/entity @db id)) to get entities out of the db, but want to use seqable functions on them.
17:41	justin_smith	Mordus: have you tried (into {} entity) ?
17:45	Mordus	Justin, thank you.
17:46	spuz	I would like to run something like (time (x)) without printing the value of x to the repl
17:47	spuz	is that possible?
17:47	amalloy	(do (time (x)) nil)
17:47	amalloy	ie, construct an expression that does whatever side effects you want (here, timing (x)), and then returns nil
17:48	spuz	amalloy, ah yes do
17:50	spuz	Is there a cleaner way to find the index of an element in an array? https://www.refheap.com/947b1ecd160ffbe6e7111d97d
17:50	spuz	this code feels very procedural
17:52	patham9_	hi! are dependent types already usable in core.typed?
17:57	amalloy	spuz: why do you want indices to begin with? usually when you are dealing with indices in clojure you are missing a better solution
17:59	spuz	amalloy, I need to store a value of true or false for every number up to a limit
17:59	spuz	I also need to search that array for values that are true or false
18:00	amalloy	if you're implementing the classic prime sieve, you should never need to search the array
18:00	sdegutis	I agree with amalloy.
18:01	spuz	amalloy, really? how do you find the next prime to eliminate the multiples of?
18:01	amalloy	just keep counting up by 1
18:01	amalloy	and skip elements that are false
18:01	sdegutis	amalloy: i like ur style
18:02	spuz	ok, that's what I'm doing
18:03	amalloy	the reason your array search feels very procedural is you're implementing a procedural algorithm procedurally
18:05	spuz	amalloy, so I can't avoid it?
18:07	amalloy	personally i would inline this function into the main sieve loop, but you can't avoid doing something with this general flavor
18:07	amalloy	otoh if you were using a bitset instead of an array, it has relatively efficient methods like https://docs.oracle.com/javase/7/docs/api/java/util/BitSet.html#nextSetBit(int)
18:08	spuz	that's pretty handy
18:09	amalloy	internally, that's just a loop 1/64th the size of yours
18:27	TEttinger	I <3 bitsets
18:28	TEttinger	RoaringBitmap and JavaEWAH are good libs for compressed bitsets when you want lower memory usage and faster set operations on multiple bitsets. JavaEWAH has a Clojure binding too.
18:38	rhg135	are they immutable though?
18:38	amalloy	as immutable as an array of booleans
18:38	rhg135	ah
18:38	amalloy	well, a little less so, i guess, but it's comparable
18:38	amalloy	and spuz is using an array of booleans already, so...
18:39	rhg135	mutability makes me sad, but eh
18:39	spuz	I better go but thanks as always for the help
22:51	patham9_	hi
22:51	patham9_	What's the state of dependent typing in Clojure?
22:52	TEttinger	there are people here who could probably answer that, but I am not one of them
22:53	awwaiid	is that different than core.typed?
22:58	patham9_	core.typed has static typing / occurence typing, but I'm not aware of the state of the dependent types
23:00	TEttinger	patham9_: it's in the "upcoming" list for the main dev http://ambrosebs.com/
23:10	TEttinger	patham9_: there aren't a whole lot of languages with good support for dependent types, as far as I can tell. Perl 6 could be added to this list https://en.wikipedia.org/wiki/Dependent_type#Comparison_of_languages_with_dependent_types
23:17	patham9_	interesting
23:20	TEttinger	didn't know ATS had good support. it's consistently near the top of the cheesy benchmarks game, a.k.a. "how fast can we call a library with hand-optimized assembly to do it for us instead of solving the task idiomatically"
23:21	patham9_	can't wait to see this in core.typed :)
23:21	TEttinger	heh, it is a neat feature
23:22	patham9_	occurrence typing is already pretty near dependent typing
