Ubuntu Drupal and multiple Virtual Hosts

A few months back I completed a small project to enable a simple single sign-on approach to product level information access. This wasn't a replacement for OpenID or anything like that, for that would be a crazy thing to take on. What I did was to build a way to assess whether a user had subscribed to one or more information resources within a site that contains many resources. What I created leveraged cookies, an expiry system, and the restful API. This was all good.

To develop all this I used an old Dell Inspiron laptop running a UAMP (Ubuntu, Apache, MySQL, PhP) stack. The project is now running in DEV and is moving into QA so I still need my development environment. I've got another development project where I want to evaluate the quiz / question modules available within Drupal and I want to create another virtual host on the UAMP development server. This is what I did to set up another virtual host in addition to the localhost already being utilized by the restful API project;

1) added a drupal to the hosts file with the IP 127.0.0.2

127.0.0.1 localhost
127.0.0.2 drupal

2) added a new file to the /etc/apache2/available-sites folder
3) edited the new file to include the correct virtual host entry pointing toward the drupal directory

<VirtualHost 127.0.0.2>
DocumentRoot /var/www/drupal/
</VirtualHost>

4) enable the site using the a2ensite command with the new file as the parameter
5) restart apache

All good. Now in the local browser I can run an instance of drupal being hosted at http://drupal

How public education should provide ROI on my tax dollars

A month ago I was questioning the value of a University Education. Don't get me wrong, I think higher education is an awesome thing and I believe everyone should (and needs to) be a life long learner. I was just questioning the value of getting higher education at a University. I think there are better ways, particularly when you consider the cost (personal and through taxes) of attending a University. To me the better ways are through what is now available via the Internet (asynchronously 7 x 24). And considering the body of work regarding the different learning approaches (constructivism, connectivism and progressive inquiry apply very well, IMHO) and how these approaches are being incarnated on the Internet it becomes a compelling alternative to traditional higher education.
So all my questioning of the value of higher education was initiated from a few tweets with someone from the PR dept. of a local university and they asked me some great questions about where I was coming from on all this. The question that really stood out for me became;

"What I deem to be a worthy ROI on my tax funded educational investment?"
  1. free access to research data - As a taxpayer I shouldn't have to pay for data or research that was created because of grants or the funding coming from tax dollars. There is great progress being made here as evidenced by much activity (a couple of examples; open access at Concordia, and the recent open access week at SFU). I look forward to all tax payer funded data and related publishing being available as open data. Suggestion: all grants, funded research, etc. should have openness written into their terms.
  2. pedagogically aware professors - modern academic institutions haven't traditionally focused on the faculty having strong pedagogical skills. There is work going on here, though I do not feel it is enough. My experiences in working for the Instructional Development office of a major Canadian University provided me insights into how graduate, post-graduate and new faculty are developing pedagogical skills, but existing faculty are slow on the uptake. I do think a younger faculty population will make a big difference here, but weve got 10 to 20 years before the scale tips in the students favor. Do I believe my academically very successful daughter should attend a University in the next decade? Considering the Higher Education (HE) faculty pedagogical skills and the use of technology to support learning by HE institutions I believe she may better spend her time elsewhere... time will tell with this; it is good to see the Society for Teaching and Learning in Higher Education (STLHE) has published ethical principles in university teaching and they include a principle on pedagogical competence. Suggestion: all faculty should have mandatory pro-d with focus on pedagogy.
  3. improved assessment techniques - assessment still seems like a game show to me - executing exams, writing papers, completing projects and their subsequent grading doesn't capture what a person has learned during a period. Using these "traditional" approaches as a way to assess peoples knowledge on a subject is disconnected. When I think of the explicit knowledge vs. tacit knowledge that a person acquires (needs) to be successful. And when tacit knowledge is considered a greater part of our knowing I just don't see strong evidence that traditional assessment methods capture a persons knowledge on a subject. I believe that much better assessment techniques need to be developed in determining a persons capabilities and knowledge. A greater amount of effort needs to be focused upon assessment within academia. Suggestion: all institutions should have or participate in a center for assessment excellence. Active research should be going on here.
  4. transparency and reduction of institutional boundaries - it seems to me that academic institutions are internally focused and overly competitive with each other. In a time where it is apparent that our future is knowledge based and our national (global) economic success is dependent upon our "national intelligence" our tax dollars should go to the greater good instead of funding intra-institutional dysfunction. As an example, why every time I apply to a new institution should I have to pay a fee to get all my transcripts transferred to the new institution? Shouldn't a national database of my academic accomplishments be available? Wouldn't it be nice to have a publicly available transcript served up by the institutions I have attended. As we move into a time where learning is more self-directed, we should be able to cobble together educational activities (courses, workshops, groups, etc.) without having to be conscious of which institution they are being made available. Should we leverage the course materials created by all Canadian institutions in similar subject areas? How different are the learning outcomes for all the same undergraduate courses across all institutions? How much tax payer $$$ are spent in duplicating the same course materials across Canadian institutions. If I was getting good ROI, institutional boundaries would have been eliminated years ago and I would have open access to my educational accomplishments and the accomplishments of the institution and its faculty. Suggestion: national online registry for transcripts (funded by students/alumni requesting transcripts); Incentives for more frequent publishing of OER.
  5. cross institutional shared services - almost every public institution has a their own registrar, network and server farm, library, bookstore, publishing abilities, website, mail server, etc... why? I do not feel this is a good return on my tax dollars. All public institutions should be using our tax dollars more wisely by administratively getting together and creating shared services in all (or at least most) of these areas. There exist many examples of all these services available online. I'd like to challenge all publicly funded institutions of learning to work together to make use of shared services. We do have examples of this in BC with BCCampus... somehow we need to provide incentive to public institutions to adopt a shared services approach. Suggestion: reallocate funding toward shared infrastructure and provide the resources to make it really easy for institutions to adopt a shared services approach.
  6. increase in blended approaches (reduce physical travel) - A lot of the content that makes up a course does not need to be consumed on campus. A lecture can easily be put online (either live streamed or archive), and if discussion is required a companion chat could be available for the live streaming and an asynchronous discussion can be available for the archive. Readings, self-assessment, discussion groups, podcasts, webinars, etc. can all be facilitated online. Therefore, when students do show up on campus this should be honored with pedagogically exceptional face-to-face learning experiences all supported by the online materials. All the lecture halls could be converted into hives of learning activities. If each HE course had > 50% of their required content online, the institutions could double their capacity without having to create new physical seats / classrooms. That creates a lot of capability without a large investment. Particularly if the institution uses the shared services approach mentioned in item 5. Then what they really need is an increase in their online faculty. Suggestion: increase focus on international, remote and adult students need for education (7x24), recognize revenue potential. Increase number of teacher faculty to take on super-mentor role.
  7. reasonable priced graduate tuition - inspiring minds and emptying wallets; > $48,000 to get an Ed.D; > $28,000 to get a professional level PhD; that's a lot of money! When you think about the importance of highly skilled and knowledgable people are to a knowledge based economy, shouldn't my tax dollars be going toward easing our best and brightest to complete all the higher education they can get. Therefore, increasing our nations competative advantage and increase global investment due to our highly skilled workforce. nuf said! Suggestion: find ways to give it ALL back! Tax credits for completed graduate studies.
  8. greater completion rates - a 2004 study found that both graduation rates and times to completion are problematic within graduate study programs across Canada. Upon further review it would seem that completion rates are lower in undergraduate programs. As a taxpayer I would like to see greater focus on completion. The amount of resources used in getting people into higher education (HE) and the costs that go into every year they stay is a poor return when over 30% don't complete. Suggestion: have faculty based super-mentors ensure greater completion rates; follow up, collaborate, encourage and cajole.
Given my potential direct investment of > $30,000 and who knows what from taxes, do I believe my daughter should spend six years in a University environment acquiring a Masters level credential? Given the age of my daughter I've got four years to decide, and unless I see changes toward what I have written above I honestly believe putting her in such an environment may be a disservice to her. IMHO it would be better for me to use the > $30k to support her self directed pursuits, help her create an effective PLE and find her some great super-mentors.

What I also find interesting is the potential positive impact what I am requesting would have on our economy and resilience as a nation. I also believe I am not alone in my thinking...

LAMP Development Server

So as many of you know I have been working toward a bunch of stuff that includes software development using a Linux (Ubuntu actually), Apache, MySQL and PhP (LAMP server). To go even further with this, my software development includes using a RESTful approach to interoperability and a deep commitment to Test Driven Development (TDD). Getting to this point has included much research and many decisions along the way. I pretty much feel my 25 years in software development, in particular, 12 years as a solutions architect has gotten me to all these decisions. I really don't want to simplify my rationale, and that is a whole other conversation that makes a lot of sense also within the context of opensource, OER, online education, agility, etc... Soooooo.... this is what I have done in the last couple of days to upgrade my old DELL Inspiron 6000.
  1. re-install of Ubuntu 9.04 to the production release (I've been running beta for while, I wanted some cleanliness and certainty to the release). - the big deal here was getting a plain old CD-R to burn the iso file onto. The more expensive CD-RW kept hanging on the install, I read a forum post about this. Simple is better when burning an iso it seems.

  2. Once Ubuntu 9.04 was up and running (which was real easy after the CD-RW issue was resolved) I ensured the update manager had done its work in getting the new install up to date.

  3. Then I proceeded to use the Synaptic Package Manager to bring in all the additional software I required, the list included;

  4. i) Apache
    ii) MySQL
    iii) PhP
    iv) phpMyAdmin - its a great tool to assist with database admin and development
    v) cURL - well, I'm going to be doing some REST development, so I need some help.

  5. Once all the software was installed I had a few configuration issues to deal with, these included;

  6. i) setting the permissions on the /var/www directory so I could add and alter files and folders. You may want to do this in a different way, for me i wanted to work under the /var/www directory.
    ii) this also meant I had to add my Ubuntu user id to the the admin and sudo groups and also edit the sudoers file to not prompt me all the time for a password.
    iii) I also stumbled upon an idiosyncrasy with the default collation with mysql it defaults to swedish, so add the collation-server = utf8_general_ci config parameter to the my.cnf helps here.

  7. I then downloaded the tar.gz for simpletest and installed into the www folder. I used the tar.gz instead of what was available through the synaptic package manager cause the synaptic version was missing a couple of files, in particular the critical autorun.php. I also allowed the Ubuntu Archive Manager to prompt me for the folder to extract the files.
So, in the end that was a days work with all the reading and research, banging my head, testing and getting it all running. In the end I did it twice yesterday, once on my Dell Mini 9 running Ubuntu 9.04 netbook remix in beta while I was trying to figure out why the initial inspiron install was hanging. Don't mind that though, gave me a chance to play (sandbox the install and configuration) in preparation for getting it done right once the inspiron was ready.

A farm for the future

Particularly in the west, we've created a way of life that is fundamentally unsustainable. It is becoming increasingly evident that we are going to have to quickly change from using past sunlight (oil reserves) to using current sunlight. This will be a huge (HUGE) change in how we do things. This BBC two produced documentary is a good look to where things will have to go.


The way forward could follow permaculture approaches. This is a food growing system based on natural ecology. As time passes through the next century the human species will likely move toward re-ruralization and increasing percentages of the population will needs the skills and knowledge to utilize permaculture or like approaches to food production. What role are you going to fill?

Island based high-density village references please

Over the last few months I have become increasingly drawn into this CRC discussion. The one thing that has made the most sense is; to inform myself. I've read through much of the three websites of;
I also created a custom google search engine and pointed it at these three sites. This search engine can be found on this blog.

The one thing I am trying to find information is research, reference or case studies about successful high-density eco-villages on ISLAND environments. So far I have found none in any of these three websites, I could have missed something. As I expanded my search to the internet and architectural, social planning, human geography references I found very little on this subject. What I did find was references to building upon what you already have. Nothing on creating NEW villages. And when I looked at the village concept it pointed toward FIRST building density at the islands port (in our case, snug cove) and secondary or tertiary villages at major crossroads. This also seems to be the most natural and proven approach to densification of islands.

What I am looking for is the references that people are using in regards to building high-density sustainable villages on ISLANDS. I believe our being an island is a important factor in deciding the location of such eco-villages.

OER roadmap

I've been working on a wiki based open educational resource (OER) project for a couple of years now. I work on it because I feel very well aligned with the sites main page description;
We're turning the digital divide into digital dividends using free content and open networks.
As an active contributor to this wiki I feel I have benefited greatly from contributing. As a contributor I believe I have learned more than any individual content consumers (though I have no data to back this up, its just a feeling). I have come to believe that contributing to OER is the best way to learn from OER. It is the act of finding existing OER and reusing it or building upon it. If the OER doesn't exist for your chosen topic, then you have the opportunity to learn and build a new piece of OER.

I am currently involved in more than one discussion about how to encourage people to collaborate in the creation of OER. This is an interesting subject for I believe a number of factors impact OER collaboration. These factors are;


  1. OER saturation

  2. Licensing models

  3. Platform

  4. Localization

How these factors impact the growth of OER is best described within what I see as the OER roadmap. The roadmap has four phases;


  1. Build-up - saturation of the subject areas from both an access (bandwidth, connectivity and platform) and localization (culture, language, etc.) perspective so that re-use is all that is left

  2. Reuse - deepening the accuracy and diversifying the learning approaches and through a licensing approach (CC-BY-SA) that encourages reuse

  3. Assessment - a maturing model of open access assessment (OAA1)

  4. Accreditation - a globally recognized model of open access accreditation (OAA2)

I still see OER at the very beginning of the build-up phase. And given the solitary preparation methods many teachers already use, it is still a long way off to have saturation. I do believe the day will come. The other three are currently being worked on, but are dependent upon completion of the first to become mature.
