Revision 13.
</p>
<p>This script recursively scans a given path and applies a cleaning 'action' to matching files and folders. By default files and folders matching the specified (.endswith) patterns are deleted.</p>
<p>It is designed with simplicity, extensibility, portability, class-based and commandline usage, and most importantly, permission-based operations in mind: i.e. it tells you what files/folders are going to be affected and asks your permission to proceed.</p>
<p>It is also very easy to extend with more intelligent pattern matching (e.g regexes, glob patterns) and other path operating cleaning functions. For convenience, one should place the script in your path and call it something like 'clean':</p>
<pre><code>Usage: clean [options] patterns
deletes files/folder patterns:
clean .svn .pyc
clean -p /tmp/folder .svn .csv .bzr .pyc
converts line endings from windows to unix:
clean -e .py
clean -e -p /tmp/folder .py
Options:
-h, --help show this help message and exit
-p PATH, --path=PATH set path
-n, --negated clean everything except specified patterns
-e, --endings clean line endings
-v, --verbose
</code></pre>

Revision 5.
</p>
<p>dbdict: a dbm based on a dict subclass.</p>
<p>On open, loads full file into memory.
On close, writes full dict to disk (atomically).
Supported output file formats: csv, json, and pickle.
Input file format automatically discovered.</p>
<p>Usable by the shelve module for fast access.</p>

<p>I had mistakenly checked in .pyc files into svn, So I took this approach of deleting all the .pyc files in the current working copy directory tree and then using svn remove to the remove from the repository. The following is the snippet I wrote then to for the purpose.</p>

Revision 3.
</p>
<p>This module provides several functions that covert earth seconds into paratessares time. It is used to implement time keeping on a fictional planet and is the standard time system of Tessaressunago. It can be used as an inspiration to other people creating their own units of time or as partitioned timestamps that can be applied to records. There are four different modules listed below: the standard implementation, a unit test, and two examples. To see the Python 2.5 version of this code in action and to test out its functionality, you can go over to the Utility Mill and find Paratessares_Time in the library ( <a href="https://utilitymill.com/utility/Paratessares_Time" rel="nofollow">https://utilitymill.com/utility/Paratessares_Time</a> ).</p>

Revision 3.
</p>
<p>This program will make your cpu work at a given cpu usage. It should be also able to work on machines with multi-processors. The program has been tested on Windows xp sp2 with python of version 2.5.4.</p>
<p>The implementation is based on the fact that it will adjust the ratio of being busy over being idle in the main process to approach the target cpu usage rate. </p>

Revision 2.
</p>
<p>I needed multiple consumers to retrieve data from a queue fed by one producer. Could not find a good working code for that, so I implemented my own queue. Docstring should describe how this works.</p>
<p>Two notes:
1) my code uses multiprocessing code, but in this module, the Lock and Condition could be easily replaced with the same objects from the threading module
2) the attached test uses syntax for "nose" testing package, I did not convert it to doctest or UnitTest.</p>
