I may be a little slow finding somethings but for all you others out there that haven't heard of Google Web Toolkit check it out. GWT allows web developers to write rich UI applications in pure Java and then compile them to Javascript for the web.  Google provides a very nice tutorial that walks developers through writing a stock watcher application. GWT comes complete with it's own Eclipse plugin and Google Apps integration.  After just finishing a Java class for my associates degree I was able to follow the tutorial with ease.

PyProfanity is a small program I whipped up to be used by a clients guest book posting routine.  The whole point is a simply way to prevent guests and spammers alike from posting profanity and sexually explicit content in their messages.  I have set up a simple cherrypy app here to allow people to try it out and help me add to the wordlist.  I have access to a log that lets me see everything tried so I can see how effective it is.  Anyone is welcome to test. The code is simple enough to post directly on here so here it is.

import re

class ProfanityFilter:
 
    def readProfanities():
        profanities = []
        file = open('wordlist','r')
        for line in file:
            line = line.strip('\n')
            profanities.append(line)
        return profanities
 
    profanities = readProfanities()
 
    def replaceProfanity( self, query ):
        for w, profanity in enumerate( self.profanities ):
            replacement = ''
            for c in range(len(profanity)):
                replacement = replacement + '*'
            p = re.compile(profanity , re.I)
            query = p.sub(replacement, query)
        return query

For obvious reasons I am not going to post contents of 'wordlist'. If you would like a copy of it send me an email.

Suggestion and improvements are welcome.

Due to school work, work, work, and more work.  I was not able to complete PyPal as soon as I planned.  I have however gotten my first Pypal site up and going.  It is a site that was made for a local artist to be able to sell her artwork.  None the items are linked to an actual PayPal account because she hasn't had a chance to set one up yet.  In the near future hopefully I will have time to strip it down to a more genral version that other people can benefit from.  Although a huge goal of PyPal was ease of manageing items up for sale, for obvious reasons you will not be able to access the admin portion of the site.  As a demo the site is currently available at the following link.  LoriArt

It should be noted that http 408/409 errors are an occurrence when using internet explorer.  Firefox work perfectly.  If anyone knows why this would happen I'm all ears.  The site is cherrypy running behind apache using mod_proxy.

Edit:

Problem solved thanks to the cherrypy googles group.

Adding "SetEnv proxy-nokeepalive 1" before the"ProxyPass" lines fixes the problem.  It is an error is cherrypy 3.1.  More on the issue http://cherrypy.org/ticket/853.

 
I work at a school that uses Fedora for Linux servers.  I'm constantly complaining about the use of Fedora and suggesting that we be using Ubuntu.  This is primarily because I've never really used Fedora so I don't know the directory structure pertaining to where everything is.  On top of that I'm not familiar with the yum package manager and RPMs in general.  While we were setting up a Fedora web server for the robotics team the coworker suggested that he installs and uses nothing but Ubuntu for a month and I install and use nothing but Fedora for a month.  Although it was never really considered I have decided to do this and the Fedora ISO is downloading as I type this.

In one month I  will write a Fedora Vs. Ubuntu review.  Stay Tuned....

Maybe this is well known to everyone but me, but it stumped me for a while so I thought it was worthy of pointing out a more logical way then what others online say to do.  I had the problem of setting a selection option from a drop down in an html form based off of a variable passed to my html template.

Everyone on line seemed to suggest using if statements to determine if the particular option should have the "selected='select' attribute. So I went that route.

Bad Way

 
<select name="letter">
<option value="A" py:if="$object.letter=='A'" selected="select">A</option>
<option value="A" py:if="$object.letter!='A'">A</option>
<option value="B" py:if="$object.letter=='B'" selected="select">B</option>
<option value="B" py:if="$object.letter!='B'">B</option>
<option value="C" py:if="$object.letter=='C'" selected="select">C</option>
<option value="C" py:if="$object.letter!='C'">C</option>
</select>
 

Good Way

 
<select name="letter">
<option value="$object.letter" selected="select">$object.letter</option>
<option value="A">A</option>
<option value="B">B</option>
<option value="C">C</option>
</select>
 

I find this lets me generate drop down boxes with the least amount of code
