We were lucky enough to host PGConf Philly 2018, the third year we've hosted the conference for PostgreSQL at The Wharton School. The event brought PostgreSQL enthusiasts from the east coast together for an afternoon of learning, sharing, and fun. Jim Mlodgenski started the event showing some trends in PostgreSQL growth; Philadelphia is the third largest local PG group, behind only New York and San Francisco. Yes, we're bigger than Chicago, Seattle, and Austin!
It was quite a beauty for its day. CDnow started off as a Telnet store, back in the days when people did not even consider the danger of sending your credit card details without encryption. When the CDnow web site was developed, there were not many mature web servers available, so the founders wrote their own in C, called "mserver" (or, Matt's server, after Matt Olim, co-founder). On top of C, Matt started a language called SDK (Site Development Kit), a scripting language tied to Oracle which did many things far ahead of its time.
