PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

The difference is that I avoid modifying the mod_utils.c and the mod_proxy.h so that if the mod_proxy module has been embedded in the main httpd binary then it will work and you won't get the

From SocialCalc to EtherCalc

Previously, in The Architecture of Open Source Applications, I described SocialCalc, an in-browser spreadsheet system that replaced the server-centric WikiCalc architecture. SocialCalc performs all of its computations in the browser; it uses the server only for loading and saving spreadsheets.

For the Socialtext team, performance was the primary goal behind SocialCalc's design in 2006. The key observation was this: Client-side computation in JavaScript, while an order of magnitude slower than server-side computation in Perl, was still much faster than the network latency incurred during AJAX roundtrips:
