Today's acronym: SS2PL

SS2PL stands for strong strict two-phase locking; it’s a locking mechanism widely used in database systems today. It is based on the notion of two-phase locking:

  • Expanding phase: locks are acquired and none are released
  • Shrinking phase: locks are released and no new locks are acquired

In addition to the above requirements, SS2PL requires that both read and write locks are held until the transaction that acquired them has commited. Essentially, this means that there isn’t a shrinking phase — only an expanding phase. May I ask why, then, is it called strong strict two-phase locking and not something completely different?

I love computer science acronyms.

Brian Lam's account of Steve Jobs

On the Gizmodo iPhone leak:

“Hi, this is Steve. I really want my phone back.”

He wasn’t demanding. He was asking. And he was charming and he was funny. I was half-naked, just getting back from surfing, but I managed to keep my shit together.

The single best remembrance piece I’ve read on Jobs.

Panic's tribute to Steve Jobs

We started Panic with two things: $500, and a love of the Mac. We had no idea what we were doing. Fortunately, someone else did.
