change maximum memory for coldfusion 8

aaron — Mon, 01 Mar 2010 16:03:47 +0000

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

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

aaron — Mon, 22 Feb 2010 18:25:46 +0000

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:

Choose menu "Tools"
Choose menu item "Folder Options"
Choose tab "View"
Enable "Show hidden files and folders"
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

aaron — Fri, 12 Feb 2010 20:24:56 +0000

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

it handles options with possible responses of needs
debugging with a flag
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

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

aaron — Thu, 04 Feb 2010 07:12:58 +0000

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:

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

Ideas for the next version:

Prompting of cleaning up world writable files
Storing ACL for each file into a database for tracking history
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"

Simple note taking and organization with TiddlyWiki

aaron — Thu, 04 Feb 2010 07:00:12 +0000

I have really found TiddlyWiki to be of great help. I have been using them on a usb memory stick for a couple months now and have grown to like it for capturing data, links and other info.

My favorite things about the TiddlyWiki are:

Its all in one html file
Searching is fast
Composing a note is simple
Notes can have references
1. this makes for an option of opening all of the relative notes at one time (very cool)
2. linking notes together with out having to type specific info into the note itself
Timeline shows what you have been working on recently
Orphans show unused notes

I am sure there are plenty more benefits to using the TiddleWiki system. If you have any, please add them to the comments!

making apache modules load with better config while using a nice bash trick to parse with $IFS

aaron — Fri, 15 Jan 2010 19:41:09 +0000

When keeping your Apache configuration clean, I like to use the Ubuntu example of loading all of the modules from includes by using:

Include ../mods-enabled/*.conf

Inside each of these .conf files is a line that loads the module like:

LoadModule dir_module /usr/lib/apache2/modules/mod_dir.so

I like this idea because then all of your settings for each module on a global level are very well organized. But when all of your LoadModule commands are in one configuration file like I had, it can be annoying to get them all into individual files. But I would like to share with you how I moved my LoadModule lines from a text file, to individual files with the bash shell:

First, you have to set your $IFS variable, then use the next line to break out the individual lines into their separate files:

IFS=$(echo -en "\n\b")

for a in `cat modlist`; do FILE=`echo $a | awk '{print $2'} | sed -e 's/_module/.load/g'`; echo "$a" > $FILE; done
