Notes.

It’s been a pretty wet week here in New Zealand. I’ve been working on Deps and experimenting with Google’s new Cloud Spanner. I’m liking what I’m seeing so far, I’ll put together an article with my experience in a few weeks.

-main

• Bill Piel is looking for feedback on Sayid PRO, a tool to debug and profile Clojure in production
• A (somewhat heated but still valuable) discussion on Navigators, Lenses, and Specter.
• Counting lines 60x faster than wc with core.async

Libraries & Books.

• Is someone writing a Datomic book?

Foundations.

• A scary study showing how distributed storage systems (Cassandra, Zookeeper, Kafka, e.t.c.) handle file system bugs (or don’t handle them).

Recent Developments.

• CLJ-1860: 0.0 and -0.0 compare equally, but hash differently
• CLJ-2123: Lighter-weight aliasing for keywords

Misc.

• Metrics That Matter
