Sampling tools like oprofile or dtrace's profile provider don't really provide methods to see what [multithreaded] programs are blocking on - only where they spend CPU time. Though there exist advanced techniques (such as systemtap and dtrace call level probes), it is overkill to build upon that. Poor man doesn't have time. Poor man needs food.

Don't ignore your dreams; don't work too much; say what you think; cultivate friendships; be happy.

1. I wish I'd had the courage to live a life true to myself, not the life others expected of me.
2. I wish I didn't work so hard.
3. I wish I'd had the courage to express my feelings.
4. I wish I had stayed in touch with my friends.
5. I wish that I had let myself be happier.

Life is a choice. It is YOUR life. Choose consciously, choose wisely, choose honestly. Choose happiness.

The AppleMods Loader system is a simple yet capable module loading system for the AppleScript language. It consists of the following:

The AppleScript-based Loader module provides a number of commands and objects used to load modules into a script.
The AppleModsTools scripting addition is used to embed a copy of the Loader module in a script.
A number of ready-to-use modules can be used for common tasks such as performing math calculations and manipulating lists.

Auto Underline
New Line with List Item
Markdown List Clipping
Markdown Create Table Clipping
Markdown Create Table Row
Prettify Table

Use WhereInOF with:

tasks where (creation date ≥ <dte1>) and (modification date ≤ <dte2>) and (completed is false)

If (old)SQL databases were fit for (new) purpose, there would have been no need to (re)invent with #NoSQL databases
