Clojurians Log v2

Just to let y’all know I am on my way, looks like I’ll be there just about 6, though may a few minutes after.

Thanks for coming to the talk tonight. My slides are available here: https://docs.google.com/presentation/d/1Z774le3MvqBzZJ907heKJ6Nle26uqzr_ywK19ORVwsY/edit?usp=sharing

the accompanying clojure file I used when developing the talk is here: https://github.com/kyleburton/talks/blob/master/2019.macros/scratchpad/src/scratchpad/macros.clj

The tricks I mentioned were: juxt instead of a hash function. E.g. (juxt count identity) instead of #(list (count %) %) (doto println) (or (doto tap>)) for temporarily logging the value of an expression, this is especially useful with the thread first macro:

(-> it ... (doto println) ...)

(This is Ed)

It was great to meet everyone, I need to come down more often

Yes, it was great to meet you too.

And for anyone interested in the podcast I'm one half of, head to https://clojuredesign.club (or look in your local podcast directory)

We have a channel on here too: #clojuredesign-podcast

@fiddlerwoaroof (Missed the meeting, no sitter last night, hi I’m Jacob 🙂 ) I’m curious about the hash function! How did hash functions come up? I use these to avoid duplicate work on the edges of my system. I recently found a thorough one here https://github.com/replikativ/hasch

@bocaj by hash function I meant the #(...) syntax for lambdas

This "thread last" example was in the slides (sorts a list of strings by its length):

(->>
   ["sort" "this" "by" "length"]
   (map #(list (count %) %))
   (sort-by first)
   (mapv second))

(->>
   ["sort" "this" "by" "length"]
   (map (juxt count identity))
   (sort-by first)
   (mapv second)
