An alternative to custom objectclasses: the extensibleobject
I’ve spent a decade designing and implementing LDAP directories, but only recently had the opportunity to reflect on the big picture. For example, the basic structure of the environment originally put in place at the company I work for by the consultants who started things is still there, but as time marched on things [...]
Using OpenLDAP schema in Red Hat Directory
Just the other day I finally got started working on building a real personal address book backend in the home LDAP database. Almost immediately I realized the base schema was going to have to be extended because there were no attributes for date of birth or anniversary, two data points that would be useful to [...]

Desktop background colors
Been screwing around with different desktop background colors tonight and needed to make a note or two.
This color chart is a great resource. All 216 “Netscape” colors, rendered more or less accurately (at least on my monitor).
