WebTrends Analytics 8.x is a Windows based log analyzer to produce graphs and reports of your website traffic. As your users are generating reports, it is helpful to find out what they are doing. Here is how you can accomplish this task:

1. Goto 'System Managment -> Role Settings'
2. Click on UI Server
3. Enable 'Use local settings'
4. Place a checkbox in 'Enable Tomcat logging'
5. The log files are located in: 'c:\Program Files\WebTrends\common\jakarta-tomcat\logs\tomcat*.log

To modify the tomcat logging settings:

• c:\Program Files\WebTrends\common\jakarta-tomcat\conf\server.xml

I really like the Trac project management software. Recently I have been using it very much and customizing it to fit my needs at work. In regards with the notification system, I found that the default format was not acceptable and a custom one was desired. I added the following code to the file "/usr/lib/python2.4/site-packages/trac/ticket/templates/ticket_notify_email.txt" to have a nice date in the template:

{% python

    from genshi.builder import tag
    from trac.util.datefmt import format_datetime
    import time

    def custom_time(value):
        return format_datetime(t=value, format='%H:%M:%S', tzinfo=PST)

%}

${custom_time(ticket.time)}

My entire file looks like the following:

{% python

    from genshi.builder import tag
    from trac.util.datefmt import format_datetime
    import time

    def custom_time(value):
	return format_datetime(t=value, format='%Y-%m-%d %H:%M:%S', tzinfo=PST)

%}
{% choose ticket.new %}\
{%   when True %}\
On ${custom_time(ticket.time)} PST, a ticket with the summary of '$ticket.summary' was created by '$ticket.reporter' and assigned to $ticket.owner .
{%   end %}\
{%   otherwise %}\
{%     if changes_body %}\
${_('Changes (by %(author)s):', author=change.author)}

$changes_body
{%     end %}\
{%     if changes_descr %}\
{%       if not changes_body and not change.comment and change.author %}\
${_('Description changed by %(author)s:', author=change.author)}
{%       end %}\
$changes_descr
--
{%     end %}\
{%     if change.comment %}\

${changes_body and _('Comment:') or _('Comment (by %(author)s):', author=change.author)}

$change.comment
{%     end %}\
{%   end %}\
{% end %}\

--
${_('Ticket URL: <%(link)s>', link=ticket.link)}
$project.name <${project.url or abs_href()}>
$project.descr

I am not going to say too much about how to do this, but just provide an example of what you need to type in:

/opt/local/bin/gem install GEMNAME --http-proxy="http://proxy.server.com:80" -V

First, it might be good for you to get the total amount of free memory on your system (using -m will present the information in MB):

[root@www1 bin]# free -m
total       used       free     shared    buffers     cached
Mem:          1770       1754         15          0         74        894
-/+ buffers/cache:        785        984
Swap:         1983         74       1909

Looks like I have about 1754 MB free.

Edit the following file:

/opt/jrun4/bin/jvm.config

then change the following line from:

-XX:MaxPermSize=512m

to something higher, like:

-XX:MaxPermSize=768m

Today I got an error message of "microsoft visual c++ runtime library: runtime error ..." when attempting to run Adobe Dreamweaver CS4. This is horrible!! Here is a screen show showing what I got:

my dreamweaver cs4 windows error

My method for fixing this error on Windows XP was to do move the following directory into my Recycle Bin:

• c:\Documents and Settings\[username]\Application Data\Adobe\Dreamweaver CS4

Note: The "Application Data" folder is hidden and you might need to do the following:

1. Choose menu "Tools"
2. Choose menu item "Folder Options"
3. Choose tab "View"
4. Enable "Show hidden files and folders"
5. Click "OK"

After removing the directory, launching Dreamweaver worked! I was also surprised that I did not loose any of my site settings.

I found that all my bash scripts really bennifet with the following template because:

1. it handles options with possible responses of needs
2. debugging with a flag
3. help description of the script

This template keeps proving to be enough to start my script building. There is really nothing more to say about this so here is my template:

I really like the Ubuntu operating system and the team that is making it. I hope to make it my personal development computer once I find a nice laptop to run it on.

Finally the day has arrived where I had to make a script to build an report for the access control list attributes on all of the files on my web server. I decided to use bash because it was easy for me to do and for compatibility of future releases of RedHat. I would have much rather have done it in Python or Ruby, but ohwell. By no means is this script really complete. I have to admit that it needs better testing of the input arguments and the debugging messages are pretty bad. I wrote this script in under 1 hour. I will do better as time proceeds, but for now, it got the job done.

My script does the following:

1. takes two arguments
   1. the path to start looking for directories
   2. the file name for the report
2. builds a header with date and time of report
3. finds the users and groups and counts the amount of times they appear in the report for a summary
4. appends the full report of all the files with the ACL

Ideas for the next version:

1. Prompting of cleaning up world writable files
2. Storing ACL for each file into a database for tracking history
3. Do you have any ideas? If so, please let me know and maybe I will add them to the next version.

And now, here is the script:
