Tribulant Wordpress Shopping Cart - Canada Post Module

Issues with Tribulant Shopping Cart, especially with Canada Post module.  Need to set-up Canada Post Gateway account efficiently and integrate it correctly with Canada Post module? I re-wrote this module to work better, like the UPS module.  Be warned that the Canada Post module has issues.
Contact me for details and stories.

Tribulant implement the following free Canada Post shipping module

RVM on Centos

Installing RVM (Ruby Version Manager) on CentOS 5.6

In this blog post I explain how to install Wayne Seguin's RVM (Ruby Version Manager) on CentOS 5.6. I will be following the installation instructions for a "Single-User Installation as a standard user". I already have installed git 1.6 and Ruby 1.8.7.

What CentOS version are you running?

First, confirm what version of CentOS you're running:

$ cat /etc/issue
CentOS release 5.6 (Final)

As you can see, I'm running 5.6, but these instructions may work for earlier versions.

What git version are you running?

The RVM installation instructions recommend having git version 1.7 or later. What do I have?

$ git --version
git version 1.6.1

I'm okay with this for the moment. The standard CentOS repositories do not have a newer version; in the CentOS universe, this is the latest version of Git (although you could get a newer version by adding a different repo). If I run into trouble later, I'll have this potential git upgrade as a possible solution.

What terminal are you running?

I believe the RVM installation instructions assume you are using Bash as a terminal. Check what terminal you are using by running the following command:

$ ps -p$$ -ocmd=
ps -p$$ -ocmd=
bash -v

That tells me I'm running bash. Confirm by asking it for the specific version:

$ bash --version
bash --version
GNU bash, version 3.2.25(1)-release (i686-redhat-linux-gnu)
Copyright (C) 2005 Free Software Foundation, Inc.

Installation: Three steps

The installation instructions list three steps for completing the RVM installation package:

1. Download and run the RVM installation script
2. Load RVM into your shell sessions as a function
3. Reload shell configuration & test

We'll follow each of these in turn.

Download and run the RVM installation script

Copy the following line into your terminal:

$ bash < <(curl -sk https://rvm.beginrescueend.com/install/rvm)

For me, this produced the following output:

Initialized empty Git repository in /home/arsturges/.rvm/src/rvm/.git/

Notes for Linux ( CentOS release 5.6 (Final) )

NOTE: 'ruby' represents Matz's Ruby Interpreter (MRI) (1.8.X, 1.9.X)
             This is the *original* / standard Ruby Language Interpreter
      'ree'  represents Ruby Enterprise Edition
      'rbx'  represents Rubinius

bash >= 3.2 is required
curl is required
git is required (>= 1.7 recommended)
patch is required (for ree and some ruby-head's).

If you wish to install rbx and/or Ruby 1.9 head (MRI) (eg. 1.9.2-head),
then you must install and use rvm 1.8.7 first.

If you wish to have the 'pretty colors' again,
  set 'export rvm_pretty_print_flag=1' in ~/.rvmrc.

dependencies:
  # For RVM
  rvm: yum install -y bash curl git # NOTE: For git you need the EPEL repository enabled

  # For Ruby (MRI & Ree) you should install the following OS dependencies:
  ruby: yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel ;
        yum install -y make bzip2 ;
        yum install -y iconv-devel # NOTE: For centos 5.4 final iconv-devel might not be available :(

  # For JRuby (if you wish to use it) you will need:
  jruby: yum install -y java

For rbx (Rubinius) more then 600MB of free RAM required.


  You must now complete the install by loading RVM in new shells.

  1) Place the folowing line at the end of your shell's loading files
     (.bashrc or .bash_profile for bash and .zshrc for zsh),
     after all PATH/variable settings:

     [[ -s "/home/arsturges/.rvm/scripts/rvm" ]] && source "/home/arsturges/.rvm/scripts/rvm"  # This loads RVM into a shell session.

     You only need to add this line the first time you install rvm.

  2) Ensure that there is no 'return' from inside the ~/.bashrc file,
     otherwise rvm may be prevented from working properly.

     
  This means that if you see something like:

    '[ -z "$PS1" ] && return'

  then you change this line to:

  if [[ -n "$PS1" ]] ; then

    # ... original content that was below the '&& return' line ...

  fi # <= be sure to close the if at the end of the .bashrc.

  # This is a good place to source rvm v v v
  [[ -s "/home/arsturges/.rvm/scripts/rvm" ]] && source "/home/arsturges/.rvm/scripts/rvm"  # This loads RVM into a shell session.

EOF - This marks the end of the .bashrc file

     Be absolutely *sure* to REMOVE the '&& return'.

     If you wish to DRY up your config you can 'source ~/.bashrc' at the bottom of your .bash_profile.

     Placing all non-interactive (non login) items in the .bashrc,
     including the 'source' line above and any environment settings.

  3) CLOSE THIS SHELL and open a new one in order to use rvm.
  

Installation of RVM to /home/arsturges/.rvm/ is complete.


Andy Sturges,

Thank you very much for using RVM! I sincerely hope that RVM helps to
make your work both easier and more enjoyable.

If you have any questions, issues and/or ideas for improvement please
join#rvm on irc.freenode.net and let me know, note you must register
(http://bit.ly/5mGjlm) and identify (/msg nickserv  ) to
talk, this prevents spambots from ruining our day.

My irc nickname is 'wayneeseguin' and I hang out in #rvm typically

  ~09:00-17:00EDT and again from ~21:00EDT-~23:00EDT

If I do not respond right away, please hang around after asking your
question, I will respond as soon as I am back.  It is best to talk in
#rvm itself as then other users can help out should I be offline.

Be sure to get head often as rvm development happens fast,
you can do this by running 'rvm get head' followed by 'rvm reload'
or opening a new shell

  w⦿‿⦿t

    ~ Wayne

Notice a few things about this comprehensive output:

• Wayne has customized his installation script (which produced this file) to produce output specific to my linux distribution (CentOS 5.6). This means he provides "yum" commands, instead of, say, Ubuntu's "apt-get".
• He notes several dependencies:
  

  dependencies:
    # For RVM
    rvm: yum install -y bash curl git # NOTE: For git you need the EPEL repository enabled
  
    # For Ruby (MRI & Ree) you should install the following OS dependencies:
    ruby: yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel ;
          yum install -y make bzip2 ;
          yum install -y iconv-devel # NOTE: For centos 5.4 final iconv-devel might not be available :(
  

  We can run these commands as-is, which I'll do below.
• He gives us three steps to complete the installation:
  
  1. Place the folowing line at the end of your shell's loading files
     (.bashrc or .bash_profile for bash and .zshrc for zsh),
     after all PATH/variable settings:
  2. Ensure that there is no 'return' from inside the ~/.bashrc file,
     otherwise rvm may be prevented from working properly.
  3. CLOSE THIS SHELL and open a new one in order to use rvm.
  These three steps basically take care of steps two and three in the on-line installation instructions.
  
• It talks about editing the .bashrc or .bash_profile. This can be done by using the vim text editor at the command line from your home (~) director:
  

  $ cd ~
  $ vim .bashrc
  $ vim .bash_profile

So let's get to it.

Meet RVM's listed dependencies

As noted in the script output above, we should meet RVM's and Ruby's dependencies. I don't care about JRuby or other editions, so I'll ignore their dependencies. Copying the line from above:

$ yum install -y bash curl
Loaded plugins: fastestmirror
You need to be root to perform this command.

I need to be root, so I'll re-run the command, only prepending "sudo" in front of it:

$ sudo yum install -y bash curl
[sudo] password for arsturges: 
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: centos.mirror.facebook.net
 * extras: mirror.nwresd.org
 * rpmforge: ftp-stud.fht-esslingen.de
 * updates: centos.mirrors.hoobly.com
Setting up Install Process
Package bash-3.2-24.el5.i386 already installed and latest version
Package curl-7.15.5-9.el5_6.2.i386 already installed and latest version
Nothing to do

This tells me those packages are all up-to-date. Next, try the Ruby OS dependencies (again adding "sudo"):

sudo yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel

This gives me the following output:

$ sudo yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel

Complete!

As you can see, it found most of those packages installed and up-to-date, but it did find some new ones as well, which it installed without issue.

The next two lines I'll run together, as Wayne wrote them, split by a semi-collon:

sudo yum install -y make bzip2; sudo yum install -y iconv-devel

Without listing all the output, I'll say that these packages were found to be up-to-date.

Now that we've met all the listed dependencies, we continue by following the enumerated instructions. Step one is: Place the folowing line at the end of your shell's loading files (.bashrc or .bash_profile for bash and .zshrc for zsh), after all PATH/variable settings:

[[ -s "/home/arsturges/.rvm/scripts/rvm" ]] && source "/home/arsturges/.rvm/scripts/rvm"  # This loads RVM into a shell session.

The .bashrc file is run each time you open a Bash shell terminal window, and since we'll be running RVM througha Bash shell, this line will be invoked before we ever need to use RVM. To add it, simply copy it, open the file with vim, and paste it in as the last line in the file.

$ cd ~
$ vim .bashrc

Here's what my file looks like after I've added the line:

# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

# User specific aliases and functions
[[ -s "/home/arsturges/.rvm/scripts/rvm" ]] && source "/home/arsturges/.rvm/scripts/rvm"  # This loads RVM into a shell session.

The next step, according the instructions:

Ensure that there is no 'return' from inside the ~/.bashrc file

The script instructs us to "Ensure that there is no 'return' from inside the ~/.bashrc file,
otherwise rvm may be prevented from working properly." I checked mine and saw no such thing, so I'll continue.

Restart the shell

The next step: "CLOSE THIS SHELL and open a new one in order to use rvm." Just close and re-open the terminal window.

That's it for the script instructions. To see what to do next, we return to the on-line instructions, where we've basically completed step three. The next thing to do is see if it worked.

Test the installation

Type the following command, which should return the phrase "rvm is a function":

$ type rvm | head -1
rvm is a function

I have no idea what that does or why it worked, but as you can see, it worked for me. Now run rvm notes as recommended:

$ rvm notes

If you wish to install rbx and/or Ruby 1.9 head (MRI) (eg. 1.9.2-head),
then you must install and use rvm 1.8.7 first.

If you wish to have the 'pretty colors' again,

For rbx (Rubinius) more then 600MB of free RAM required.

This just reminds us of the dependencies we've already met for Ruby, and of the dependencies we'd need to meet if we wanted to run JRuby or rbx. Otherwise, we should be done with the installation, and ready to use RVM on CentOS 5.6.

$ which ruby

As you can see, it's important to use the "rvm use" command to actually switch to a version of Ruby installed by RVM.

Conclusion

We followed the on-line RVM installation instructions on CentOS 5.6, first running the bash script, then following the instructions output by the script, including installing dependencies and adding one line to the .bashrc file. We did this without needing to upgrade git beyond what the CentOS default repositories offer.

Summary of commands for power users

$ cat /etc/issue
$ git --version
$ bash --version
$ bash < <(curl -sk https://rvm.beginrescueend.com/install/rvm)
$ sudo yum install -y bash curl git ; 
sudo yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel ; 
sudo yum install -y make bzip2 ; 
yum install -y iconv-devel

Now place the following line in your .bashrc (but copy the one generated by your own installation, not mine):

[[ -s "/home/arsturges/.rvm/scripts/rvm" ]] && source "/home/arsturges/.rvm/scripts/rvm"  # This loads RVM into a shell session.

Next, make sure that there is no 'return' from inside the ~/.bashrc file.
Now restart the shell, and test the installation:

Google Organic Ranking in relationship to Ad Clicks

Why run a Google Ad Words search ad when your brand appears in the organic results?

It's an important question for many advertisers. Looking for an answer, Google request a research study in 2011. The ran a test by stopping paid search ads on 400 accounts across four countries. The results were dramatic. A full 89% of visits to an advertiser's site from search ads were incremental to clicks on organic results. 

• That means the visits would not have occurred without the ad campaigns.

It was surprise, even to the researchers. 

Think search ads aren't necessary when organic presence is high? Think again.


Google observed what happened to organic clicks when paid search ads were paused in over 400 accounts across four countries. Using a statistical model to estimate the incremental clicks attributable to search ads for each advertiser, we found:

• On average, 89% of paid traffic to an advertiser's site is lost and not recovered by organic clicks.

In 2011, Google released a Search Ads Pause research study which showed that 89% of the clicks from search ads are incremental, i.e., 89% of the visits to the advertiser’s site from ad-clicks are not replaced by organic clicks when the search ads are paused. In a follow up to the original study, we address two main questions: (1) how often is an ad impression accompanied by an associated organic result (i.e., organic result for the same advertiser)? and (2) how does the incrementality of the ad clicks vary with the rank of advertiser’s organic results?

 A meta-analysis of 390 Search Ads Pause studies highlighted the limited opportunity for clicks from organic search results to substitute for ad clicks when search ads are turned off. We found that on average, 81% of ad impressions and 66% of ad clicks occur in the absence of an associated organic result on the first page of search results. In addition, we found that on average, 50% of the ad clicks that occur with a top rank organic result are incremental. The estimate for average incrementality of the ad clicks increases when the rank is lower; 82% of the ad clicks are incremental when the associated organic search result is between ranks 2 and 4, and 96% of the ad clicks are incremental when the advertiser’s organic result ranked lower than 4 (i.e., 5 and below).

 While these findings provide guidance on overall trends, results for individual advertisers may vary. It’s also important to note that the study focuses on clicks rather than conversions. We recommend that advertisers employ randomized experiments (e.g., geo-based experiments) to better quantify the incremental traffic and lift in conversions from the search ad campaigns and that they use the value-per-click calculations in the original search ads pause study to determine the level of investment on their search ads.

Installing RubyGems in Cygwin

This is as much a reminder for myself as anything else – as I’ve now had to do this about a dozen times between repaving my laptop, home workstation, and work machine(s).

The How-To

Don't try to install RubyGems for Cygwin using the gem that comes with the Ruby One-Click Installer for Windows. Instead, get the tarball, or zip file, and install it using the included installer script.
Since RubyGems is pure Ruby you don't have to worry about having a compiler installed. It should just work with the default Cygwin install plus Ruby and its dependencies. To install it, do the following steps:

1. Download the RubyGems tarball from Ruby Forge
2. Unpack the tarball
3. In a bash terminal, navigate to the unpacked directory
4. Run the following command:

   ruby setup.rb install

5. Update RubyGems by running the following:

   gem update --system

Note: You may need to run the updated command twice if you have any previously installed gems.

Google Analytics Tracking Code is Broken (as of Mar 2012)

Google Analytics Tracking Code is Broken (seen Mar 2012)

{script type="text/javascript"}

  var _gaq = _gaq || [];

  _gaq.push(['_setAccount', 'UA-########-1']);

  _gaq.push(['_trackPageview']);

  (function() {

    var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;

    ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';

    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);

  })();


{/script} --- note tag change

If http://www.google-analytics.com/ga.js is not loading for you I have a fix. 

Also in the ga.js code some references fail. 

I have a fix for this - $10.00. 

FileZilla SSH fail on Windows 7 - ssh_init: Host does not exist

ssh_init: Host does not exist

http://trac.filezilla-project.org/ticket/7444 is STILL an issue using 

 FileZilla Client 3.5.3 released !

Update: A patch has been released.  FileZilla - The free FTP solution (filezilla-project.org) 

Otherwise a solution: Use  WinSCP - no problems!

It comes with open source code, so go to have options.
