Clojurians Log v2

Morning

For that last true I like to use :->

Guten morgen!

I just had to use '~k#` in some code and now I don’t know if I’m super smart or super filthy.

moin moin

bonjour à tous !

Morning

@ordnungswidrig I'm not even sure how to google that let alone what it does

God morgen!

Доброе утро!

I'm assuming @ordnungswidrig is using a nested syntax quote there

e.g.:

user=> (eval `(let [k# 'clojure.core/inc] (prn `'~k#)))
(quote clojure.core/inc)

Basically I've created a small macro to dump some expressions in a map: (prn "DBG" (binding-map foo bar baz))

Printing e.g. {foo 123 bar :whatever baz nil}

Compare?

Two tests: that one with case and one without wherr you skipped that true clause check. Criterium should be able to warmup hotspot sufficiently.

(defmacro bindings [& ks]
  (zipmap (map #(list 'quote %) (keys &env))
          ks))

(let [a 1 b 2 c 3]
  (bindings a b)) ;;=> {a 1 b 2}

Hmm, might be handy to capture function inputs:

(defn foo [a b c]
  (def x (bindings a b))) 

(foo 1 2 3)
x ;;=> {a 1 b 2}

That's only measuring. But how can we see that hotspot is really not hitting that path anymore

why not use defrecord ? it would might be less surprising... and transient stops being an issue IIRC

There's a few repls about that do that. Scopr capture too. There's a few contexts where things need to be filtered.

morning

yes, that's something I want to add to repl-repl also

this is nice

I'm foolishly waiting for a cljs&clj compatible one that doesn't require me to move to shadow.

Now that REBL is free, maybe they'll open the source and we can have a poke

Punk?

does anyone know if nubank will still be building a business around datomic or not? I know they use it a lot internally but being a bank and a database vendor seems a bit odd

(same on REBL really - dev tools and a bank?)

did you see that Oracle and Walmart are buying TikTok US ... no clue

Cognitect will remain operating as their own thing and will continue to offer Datomic consultancy

on paper

I think it will kill them selling it to other banks (banks don't like buying products from other banks. that does often mean we get nice open source things tho)

but yeah, we'll see

I hope all involved got a nice chunk of money

Maybe RH can buy himself another two years of whatever he likes to do :)

🙂

I hope more than that

@raymcdermott I thought the deal that eventually came out was that they were going to use Oracle cloud and that there wasn't anything else

> Oracle and Walmart will own 20% of TikTok Global, with respective stakes of 12.5% and 7.5%, and the data of TikTok's U.S. users will be stored in Oracle's cloud servers.

I understand that the Donald wants a kickback of $5bn to fund "patriotic" history lessons which means https://en.wikipedia.org/wiki/The_1619_Project

Morning

There’s a few bank-in-a-box startups floating about now.

Dearest Clojurians! How about a  :umbrella_on_ground: :clojureD 2021-Summer Edition? :umbrella_on_ground: Let us know your wishes & opinions! http://clojured.de/clojured-2021-… Our little poll runs until 09 October, we take a little break while you are voting and will update you with the results asap. Thank you so much in advance for your support!

A summer conference! I like it!

(also how is it possible that we never put the heart of clojure logo on here as an emoji)

oof, can't peek or pop with a transient vector

if you really need the high performance of transient and the queueing functionality, I would be starting to look in java.util.collection

the fact that Clojure makes it so easy to interact with java.util.concurrent.ConcurrentLinkedDeque is pure genius

Thx

🍻 happy weekend y'all
