@martinklepsch: thx for the pointer, i joined the convo at https://gist.github.com/bhauman/5c50a25f28598d954eba

Btw, are they any thoughts on task parallelism? Don't need it but would be nice for sure :)

@martinklepsch: the problem with running tasks in parallel is not the mapping, it's the reducing

@martinklepsch: for example, suppose tasks A, B, and C run in parallel

we can fan out very easily, just pass the initial fileset to A B and C

so they compute 3 filesets

how to merge them now? how to resolve conflicts?

yeah, that was kind of what I was getting at with the question. Mapping is trivial but reduction not so much. Still probably doable with some proper constraints, right?

yes, that's a good point

if you're doing it you should do it carefully and know what you're doing

i.e. tasks executed in parallel are limited to a certain scope (read subdir) in the fileset

i think the conflict resolution part of the git model precludes any kind of automatic parallelization

that's an interesting idea

I’m thinking just separating them might be fine in many cases, i.e. stylesheet + cljs compilation

kind of like transients or something

we can make map and reduce combinators you can use in a pipeline pretty easily i think

(defask dev [] (comp (foo) (bar) (parallel merge-fn (css) (cljs)))

something like that perhaps?

(defask dev []
  (comp
    (foo)
    (bar)
    (parallel merge-fn 
      (comp (css) (garden))
      (cljs))))

Might be worthwhile to list the typical use cases for parallel tasks to see which of them need merging and which ones, like the case of stylesheet + cljs compilation, simply need to run to completion.

i think they all need some degree of merging

i think i agree with the ember guys with their broccoli tool

I think you mean team...

no, slackbot i don't

broccoli team ftw!

guys and dudes omg pronouns

I think you mean team...

guys and gals

I think you mean team...

silly slackbot

anyway the broccoli guys found that parallization isn't a significant improvement when you have pervasive and intelligent caching at the task level

I think you mean team...

which we have with boot

i.e. boot tasks handle their own caching

so they are very good at ignoring things that don't need to be recompiled

the broccoli guys found that parallelization is most useful when work is being done more than once

I think you mean friends...

oops, i didn't see martinklepsch set that

sorry about that

i thought it was a slack thing

No worries 😄

I set that up after seeing it in another Slack and thought it’s a nice idea given that we often use words guys like guys, effectively (sometimes unconsciously) discriminating other genders, I think the auto messages are stupid though. They don’t give that kind of context.

i get it, i'm just put off by all the melodrama around the whole issue

so i go into automatic snarky mode

And sometimes I actually mean ‘guys’.

Yeah, sometimes I am too. No offense taken

it's part of my tadschlagargument style i guess

@akiva: yeah, that’s another point where @slackbot fails

is broccoli what ember is using btw?

it is

didn’t know.

@micha: @akiva for what it’s worth in that particular case: the lead dev of broccoli is actually not a guy 😉

hahaha

hi enn

Hello!

https://twitter.com/danielszmu/status/611116898948792320/photo/1

Ha, I’ve tweeted this earlier today.

yoko rules

alandipert: +1

alandipert: Normally I’ve always got a couple of favorites on my tweets. This one didn’t garner a single one. Sad.

micha: that’s the spirit!

micha: +1

🍝

we need a hummus emoticon

micha: haha, I was looking for a coconut

but yeah, we need a hummus one

man, no coconuts!?

this must be rectified

🌴 close but no cigar

🍸 close but no coconut

hahaha

🎳 almost coconuts

🌴 🎳

behold: 🥥

holy 🥥

thanks alandipert

Btw. http://clojutre.org/2015/ !

deraen: #C03RZRRMP is that way

deraen: man i'd love to go to that

No off-topic here? 😞 I'm too used to IRC

traffic is so low in here it should be alright, no?

yeah it's fine, just there are people over in #C03RZRRMP who may be interested 😛

Yeah I just wanted to share it here first as I know Micha and Martin would be interested

@juhoteperi: #C03RZGPG3.

And yeah, it’s kind of nice/irritating to have everything dumped into one IRC channel.

🥥 Wow alandipert !

deraen: Thanks for letting us know about the Clojutre event. I submitted my proposal. What does "Vastauksesi on tallennettu” mean?

danielsz: Heh. "Your response has been saved". I'll fix that.

🥥

@juhoteperi: Berlin ✈️ Tampere sucks big time. Do you know how long does a train from Helsinki takes? (and what’s the price?)

@martinklepsch: 1:15 and about 30€

Oh. I was thinking it’d take 5hrs or so but yeah, now that I look at the map 😄

Boot-livereload is now pushed to Clojars

@podviaznikov: There was a nice side-effect from using metadata for posts metadata, dates are now Date objects

@juhoteperi: do ClojurTRE tickets go fast usually or can I take a week or two to consider things?

@juhoteperi: yep, I noticed that too

@martinklepsch: They are going fast, but I'm sure there will be enough (we have quite large venue this year).

podviaznikov: I was going through the source code of perun, and I was wondering about the usage of unquote on regular function arguments, as in (io.perun.ttr/calculate-ttr ~metadata).

Or (io.perun.sitemap/generate-sitemap ~(.getPath tmp) ~files-metadata ~options))

what’s going on here?

deraen: you know something about that?
