Thanks! Great to hear positive benchmark results. I'd guess that if you did
(count (distinct (map hash your-set))) you'd see that was a lot smaller than
(count your-set) in 1.5.1 indicating hash collisions.

I'd agree with all that. One place we've seen nil but not false become more
prevalent lately is in core.async. Channels reserve special meaning for nil
(closed) but false is a valid channel value. So if-some and when-some are
particularly useful in go loops that take from a channel. There are a
Good library!

Hi,
I'm reading the second edition of Joy of Clojure (the MEAP), and there is

Make sure your db is correct,

Token authentication is a popular way to authenticate API requests over

As previously mentioned, datalog/datomic both work over in-memory data and
are excellent libraries.
You might also consider a rule engine such as Clara:

You can build individual examples, tests can't be built - it's just a

Alex's suggestion is a good way to determine whether the 10k clj-tuples in
a set case is being sped up by the new hash function -- just look at the
variety of values of (hash x) for all x's in the set and see whether it is
significantly more unique hash values in 1.6.0-beta1 than with 1.5.1.

Hi all,
My team recently open-sourced its new distributed timer service, Chronos
(https://github.com/Metaswitch/chronos). As this might be of interest to
Clojurians, I've written a Clojure client library for it
(https://github.com/rkday/chronos-client-clj).
We work on distributed high-scale
Great job on the new release guys :)
My one bit of feedback is that if-some and when-some behave like a let, but
don't include let in the name. My guess is that this was chosen because
if-some-let and when-some-let are starting to get awkwardly long.

You should try transients if you're looking to quickly fill collections -
