I was chasing down another issue (slow "Save As") and thought these two issues may have been related (with QuickLook being the common broken link). Unfortunately, my "Save As" dialog is still miserably slow on the initial load; but IconServicesAgent hasn't gone above 30MB and he rarely makes an appearance in the Console!

Some of these steps may not be necessary, but here are all of the steps I took that inadverdently put IconServicesAgent back in its place. Note: all commands are a single-line, if they appear to be multiple that's just the forum formatting.

1. Check for any QuickLooks related .plist files. In a terminal: mdfind com.apple.quicklook. -name .plist

2. I only had files at the system level (specifically within /System/Library/LaunchAgents/). If you have others, modify the directions below to take that into account (re-introducing plist files from the system level back up to the user).

3. Make some temporary directories to store these plist files, just in case: mkdir ~/tmp-quicklook

Recently someone asked me for online resources about MRI's internal C source
code. Here are a few - if there are more to add please leave a comment! - pat

1. Ruby Hacking Guide - The definitive resource for people who want to learn
the C programming details of how Ruby works internally. Intended for C hackers.
It was just recently translated into English from the original Japanese.
http://ruby-hacking-guide.github.io

2. Various presentations by Koichi Sasada - he often does public presentations
on Ruby internals and they're always fascinating and full of technical details.

After upgrading to Mountain Lion : 10.8 I noticed that I was getting Python errors which prevented me from starting vim:

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

# Mac OS X Lion introduced a new, iOS-like context menu when you press and hold a key
# that enables you to choose a character from a menu of options. If you are on Lion
# try it by pressing and holding down 'e' in any app that uses the default NSTextField
# for input.
#
# It's a nice feature and continues the blending of Mac OS X and iOS features. However,
# it's a nightmare to deal with in Sublime Text if you're running Vintage (Vim) mode,
# as it means you cannot press and hold h/j/k/l to move through your file. You have
# to repeatedly press the keys to navigate.

The purpose of all this is to see if sphinx, thinking sphinx and thinking sphinx delayed delta are all working properly.

I created a test controller on a separate monit subdomain that simply generates and posts a test value and then uses curl to retrieve it. If the two values match, then sphinx is working properly with delayed delta.

This example assumes a Linux installation.

The file 'delayed_delta.sh' spawns the `rake ts:dd` process in the background, saving its PID to tmp/pids in your Rails project. You can start and stop it by running '/etc/init.d/delayed_delta.sh start' and '/etc/init.d/delayed_delta.sh stop'. You will use these in your monitoring to, see the monitrc snippet.

In a crontab, every X seconds or minutes, run 'ar_sphinx_mon.sh' to see if records are properly being inserted and indexed. If they aren't, then kill all Thinking Sphinx processes and monit should restart them.
