Spanner: Google’s Globally-Distributed Database

Spanner is Google’s scalable, multi-version, globally-distributed, and synchronously-replicated database. It is the first system to distribute data at global scale and support externally-consistent distributed transactions. This paper describes how Spanner is structured, its feature set, the rationale underlying various design decisions, and a novel time API that exposes clock uncertainty. This API and its implementation are critical to supporting external consistency and a variety of powerful features: non-blocking reads in the past, lock-free read-only transactions, and atomic schema changes, across all of Spanner.

JavaOne ’12

Yes, the big names, the legends and the heroes are no more but fret not Oracle has managed to pull a not so shabby lineup of speakers for JavaOne 2012. Yes, it’s maturing, and maybe there’s just less to talk about, and Java’s a teenager now!

I don’t want to die in a language I can’t understand – Dick Gabriel

Dick Gabriel, a legend – “scholar, scientist, poet, performance artist, entrepreneur, musician, essayist, and yes, hacker…” speaks at Clojure/West.

Richard P. Gabriel expands upon “Mixin-based Inheritance” by G. Bracha and W. Cook, observing that software engineering precedes science and incommensurability can be used to detect paradigm shifts.
