| -- PostgreSQL cheat sheet | |
| --postgres is set up to use local.6 which is syslog'd to sflog001 | |
| --slow query log is /var/log/localmessages | |
| --config files are always in /data/friend/*.conf | |
| --vacuums are set via cfengine, we use both manual and auto. vacuums/analyze help with frozen id's being recouped, and thus TX'id's not going over 2b thus causing massing shutdown/reset. Fix it to exp/imp high TX tables. | |
| --to log into psql: psql -U postgres -d <DB> (usually friend) |
| #! /usr/bin/env python | |
| """ Convert values between RGB hex codes and xterm-256 color codes. | |
| Nice long listing of all 256 colors and their codes. Useful for | |
| developing console color themes, or even script output schemes. | |

Font size adjustment plugin for PhoneGap on Android: a simple PhoneGap plugin that allows you to dynamically modify the WebView's textSize property in order to make the text larger/smaller.
Usage:
// increase the font size by one unit (units are [50%,75%,100%,150%,200%])
window.plugins.fontSizeAdjust.increase(myCallback(newFontSizeAsPercent){});
// decrease the font size by one unit
window.plugins.fontSizeAdjust.decrease(myCallback(newFontSizeAsPercent){});
