Crypto being used outside of Facebook to encrypt communications happening via Facebook. Cool, but misses the just-as-important privacy issue which is Facebook's ownership of the social graph.

(Dumping GitHub watches into Pinboard.)

Possibly still-relevant Facebook branch of memcached.

Surprisingly funny physics jokes, via the Flengbot.

"What we've done here is made security the default."

As I read through the documentation, I realized I've built this templating engine before, sans the nice syntax they hacked into PHP. The bonus is that they fixed PHP's syntax to allow array("things", "stuff")[1].

In light of Facebook's new PHP-to-C++ compiler, remember some of their older work on APC.

Reckless speculation from last night that turned out to be horribly wrong. Actually, I like my fictional version better.

Facebook's rumored PHP improvements are not at all what I expected. Rather than going the JIT route via LLVM like the Unladen Swallow project, they've implemented a C++ code generator and are using g++. Favoring static binding is a huge win here, both for type information and function pointers. At least there's a proper interpreter to fix the development workflow they broke by wedging a manual compile step into the mix.

Facebook's SQL-to-map/reduce analytics engine.

Worth a second look

Could be better than quick stints of XDebug in production.

Hammer's talk about data at Facebook. 320 nodes for Hive, 120 nodes for Cassandra. Large data size and a (relatively) low write rate.
