Another day at the bus stop

Another day at the bust stop that got me to take a panorama of the weather. This time I saw lots of fog!

When starting Dreamweaver CS4 I get an error of microsoft visual c++ runtime library: runtime error

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:

dreamweaver cs4 windows error

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.

bash script template to be used for parsing arguments to make your shell programming life easier

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:

#!/usr/bin/env bash

# created at: Wed Apr 04 10:03:41 PDT 2009
# updated at: Wed Apr 22 15:33:24 PDT 2009
# author: aaron addleman

# manage subversion with swatch and ftp log file. all actions will be sent to a file for throttling purposes to allow SVN to handle its own lock files
# BEGIN SCRIPT
usage()
{
cat << EOF
usage: $0 options
This script takes commands from a swatch and converts to svn commands for a directory under version control.
OPTIONS:
-h      Show this message
-a   Action needed (STOR, DELE, MKD, ENTRIES, SVNUPDATE)
-u      Username to use for commits
-f      File or directory being affected
-m      message to use
-x      Execute SVN commands from the $SVNACTIONS file
(when this option is used, all others are ignored)
-v      Verbose (boolean)
-t      Test (dont run any commands, but print them to the command line)
EOF
}

ACTION=
USER=
FILE=
MESSAGE=
VERBOSE=
TEST=
while getopts "h a:u:f:m:x:v:t" OPTION

Installing Ubuntu now…

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.

RedHat Linux ACL report bash shell script

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:

    (for anyone who wishes to gen_acl_report.sh)

    #!/bin/bash

    # purpose: create ACL report on 1 level depth directories and output to text file report
    # usage: ./gen_acl_report.sh start_path report
    # the above command will generate a file called "report_20100203_YYYYMMDD_HHMMSS.txt"
