[ANN] org.clojure/core.memoize 0.8.2

2019-11-01 Thread Sean Corfield 
Pluggable memoization based on org.clojure/core.cache

https://github.com/clojure/core.memoize

New in 0.8.2:
- updates core.cache dependency to 0.8.2
- fixes a bug in the seed implementation for PluggableMemoization
- adds memoizer as an easier way to build memoization on top of custom
caches
- deprecates build-memoizer (the older, harder way to build memoization on
top of custom cache factories)

The bump in version number (from 0.7.2) is partly to signify the internal
re-plumbing to use memoizer instead of build-memoizer and partly to get
back in sync with core.cache, since the two libraries are fairly tightly
coupled.

ANN: duratom 0.4.9

2019-11-01 Thread dimitris 

Hi folks,

This new release adds a new constructor-fn `duragent`, which as the name 
implies, will return a durable agent. Unlike `duratom`, this is not a 
wrapper type - what you get is an actual `clojure.core/agent` (with a 
watch + some metadata). All the existing backends written for `duratom` 
will/should work with `duragent`.


This release includes a breaking change in the IStorageBackend protocol, 
so any backend implementors outside the duratom `project` will have to 
be careful. This was necessary in order to de-complect what is being 
committed from how it's being committed. But if you have functional 
duratom backends today, I would very much appreciate PRs ;).



Have a great month :)

Kind regards,

Dimitris

Sure: I'm saying figuring out the formula from a handful of examples is
tricky. But I can do that, and I already know Clojure has conditionals. I'm
trying to learn something about how the logic engine works.
