qlmanage - Quick Look Server tool

This is a “hidden” program design, as far as I have guessed, to show image previews without needing to open an application. The easiest way to use this quick look is to select a file in the finder and press the spacebar once. A new window will open and a large preview of the file will show in that window.

For those a little more geeky, there is a quick look manger program that can be run from the command line. The following line will open an image of a cat in the same style preview window as the spacebar will from the Finder.app (A Macworld article has further information).

Open Directory and .htpasswd

Fascinating! I worked on a project* once that involved a complete rewrite of the command-line utility passwd in order to keep a number of system services including a .htpasswd file in sync with users account passwords. Mac OS X Hints noted this is made simple with Mac OS X Leopard (10.5) and Open Directory.

Virtualized Xserver

Media Temple labs has a private beta for what it’s calling Xserve-Virtual . This system has been added quickly added to my MT wish list along with the Django GridContainer which, perhaps I wont need if I move over to a full-on-mirror of my development environment using a virtual OS X Server.

A virtual Mac OS X Leopard Server running on a fully loaded cluster of Xserves virtualized using Parallels Server . I want one, … or three, … yeah that should be enough …. maybe four, for symmetry.

Fedora 9 root password mismatch resolution

Having started my journey down the command-line with Fedora 3, I was excited to try out Fedora 9. The install completed with ease (the first time around) but once I logged onto the system and attempted to configure some of the system settings, my root password didn’t work.

Why? CAPS LOCK bit was set by default during the install process making a different root password.
