YUM Package Installation Updating and Removal Forensics

In previous posts I examined the internals of RPM packages and the RPM database itself. In this post, I explore how to trace RPM package installation, update and removal on Linux distributions which use YUM (YellowDog Update Modified). If you examine /var/log/yum.log, an example of which is shown below, you will note that the date component of each entry includes the day and month but not the year.

Adding Discrete Height Selection to Boonex Dolphin

Boonex’s Dolphin is a popular PHP/MySQL-based community software package which has been around for a number of years. It’s roots go back nearly 10 years to aeWebWorks and AEdating. As part of each user’s profile, it includes the ability to store a user’s height. Unfortunately the granularity of the select box options for a user’s height is poor. Here is the relevant part of the MySQL load script which sets up the user height selection values: INSERT INTO `sys_pre_values` VALUES(‘Height’, ‘1’, 1, ‘__4”7″ (140cm) or below’, ”, ”, ”, ”, ”); INSERT INTO `sys_pre_values` VALUES(‘Height’, ‘2’, 2, ‘__4”8″ – 4”11″
