Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Noob has simple program problem.
(criterium does not work here yet b.t.w., but it probably will be working soon)

Question about high execution time
criterium, specifically the quick-bench function, will actually run multiple samples an provide a mean runtime (as well as other useful stats) so you can get an idea of what a jit'd warmed up performance looks like. time is great in a pinch, but you end up needing to run it multiple times to ensure optimizations are kicking and and other artifacts (like gc) aren't throwing the results.

Logging in Clojure: jar tidiness
I'm going to leave tooling out of this and run everything through a repl on the command line right from the jar. One other thing I want to do is include the incredible criterium library so we can profile. I'm deliberately including criterium separately like this because you shouldn't have a dev-time tool like criterium in an uberjar. And knowing how to easily combine other jars with your real production jar can be very helpful. I grabbed the jar from my .m2 cache.

"The Genuine Sieve of Eratosthenes"
where crit is criterium. As you can see, you're spending most of your time in the seq transformation part.

A casual Clojure / Common Lisp code/performance comparison
It's better to benchmark with something like criterium. time is a bit inaccurate. Though, if it's really 15 seconds, I guess will not be that big of a difference

Fast and Elegant Clojure: Idiomatic Clojure without sacrificing performance
>>> One of Clojure's biggest weaknesses in practice is that breaking in to those functional structures to figure out where the time is being spent or to debug them is harder than in other languages. This is a natural trade-off of developing a terse and powerful language.
Not that hard if you use something like YourKit. There's also a quite good Clojure library https://github.com/hugoduncan/criterium .

Clojure, Faster
Criterium (the benchmarking library used here) uses multiple runs to obtain tighter bounds on amortized performance, as well as techniques to amortize the effects of garbage collection and JIT compilation. See https://github.com/hugoduncan/criterium for a brief overview, as well as links to the pitfalls and statistical techniques involved in JVM benchmarking.

Logging in Clojure: jar tidiness
A really nice dev experience is if your editor can connect to socket repls. Doing this makes running a repl from a jar or from your regular "dev" setup almost indistinguishable. I can easily repl from a prod jar as from a branch in Clojure and my workflow is exactly the same because I use inf-clojure

CIDER Turns 10
I have the feeling, that https://github.com/clojure-emacs/inf-clojure might be a better starting point and a good stepping stone, before they get into CIDER. (but i haven't used inf-clojure enough, so it's just a gut feeling)
-
Problem with namespaces in CIDER (Spacemacs)
maybe https://github.com/clojure-emacs/inf-clojure is a better way to get started, because you don't have the convenient magic of the nREPL protocol in the picture?
