Fix from “Tutorial: Deploying WordPress with Capistrano” by Konstantin Kovshenin

I was using the three blog posts by Konstantin Kovshenin about using Capistrano with WordPress. The blog post tutorials were written in 2011.

I kept having issues with the symlink code used in the post. The code looks like this:

namespace :myproject do
    task :symlink, :roles => :app do
        run "ln -nfs #{shared_path}/uploads #{release_path}/application/wp-content/uploads"
    end
end

after "deploy:symlink", "myproject:symlink" 

Problem: Tasks not being executed on cap deploy

Not having a Ruby background, I couldn’t easily debug the situation. To keep it short, every time I cap deploy the commands in the :myproject would not execute.

I believe the newest Capistrano no longer uses the "deploy:symlink" as a valid trigger. Therefore, the snippet originally provided was not working.

Solution: Change trigger

It’s not a fancy outcome, but I changed the line:

after "deploy:symlink", "myproject:symlink"

to

after "deploy", "myproject:symlink"

Now my symlink is run correctly and I am able to see my tasks run when I cap deploy.

This is a fix to issues I found in Tutorial: Deploying WordPress with Capistrano](http://theme.fm/2011/08/tutorial-deploying-wordpress-with-capistrano-2082/)

Acquinity Interactive hired me

I was recently hired by a marketing company to help them rebrand their digital presence. While this word is loaded with meaning, they wanted me to help them make a new website. The process is allowing me to start a development process from the complete beginning. Most interestingly, Im able to do things the right way.

Why WordPress?

I decided to use WordPress as the framework for their website. As a company of more than 250 employees, they need something that can be easily managed by otherwise untrained individuals. A straightforward CMS like WordPress is perfect for this job. For me, I prototype the website using Foundation from Zurb, then with the creative director, I find the right “style” of the website. Once we get past deciding the technical details, I can just go into WordPress and make page templates that fit out prototyped site. By using WordPress, I know that once I get past the html/css prototypes, I can translate the pages into php template files that will be populated from the administrative panel.

Why Capistrano?

This is a good question. People who think of WordPress either think of the SaaS version (wordpress.com) or blogs. Most people don’t consider it requiring a development process or a deployment strategy. Personally, I hate wasting time on things that don’t need to have time wasted on. I love to learn something new, but if I can find out how to automate a process, I’m going to take the initial time to set it up. By automating the deployment process, I know I can have consistent development environments.

Capistrano is a Ruby based package that runs SSH commands. Its largely used with Rails applications to manage various development environments (local/staging/production). Its great because at a touch of cap deploy you have your website up and running. Better yet, if you find out something broke, you just just cap deploy:rollback. In short, it’s pretty amazing because no longer do you need a designated “deployment” person. Instead, you can take time before your project begins to have the deployment strategy set up.

Why do you need development environments?

I won’t go to much into this because it’s one of the basic tenants of web development. Have a place where you develop (local), have a test environment where the site is as close to live without being live (testing), and have a separate place to have a autonomous production environment which will not be disrupted. One of the issues with these environments is that you have different files that you may be changing, but are not consistently updated.

You don’t want to screw up a site when other people may be using it. In the worst case scenario, you have files that you are working on a live site. Maybe you use the WordPress code editor, or maybe your using an FTP program to just edit the files directly on the server. In this situation, if you have a boo-boo, but don’t know whats wrong, you could lose traffic and confuse users.

In a slightly better situation, you have a local development environment and a production server. This is pretty normal. You might make your changes to your WordPress theme via a local server. You make sure the files are working and the visuals render properly. Once you like the final product, you will push the updated files through FTP. If you are really good, you will update the files via SSH.

The first example (aka cowboy coding) is all bad. The second example is not so obvious for some people. To explain most basically, FTP is very slow and error prone. Its not impossible to use FTP for site management, but its very likely that batch uploads will result in significant failed files. Yes, you can always make sure the files work by looking through your log. The point is you want to find a solution that doesn’t have any problems.

Enter Capistrano

Capistrano lets you have your local environment mirrored in other places. You can set certain folders that are not mirrored (i.e. file uploads, config files, etc), so that your updates to the site are fast and targeted. Capistrano uses SSH and Git to create your extended servers. By setting up Capistrano, you just need to develop using basic version control methods. If you already use Git normally, Capistrano is perfect for you.

Setting up Capistrano is a bit difficult for non-Ruby developers (aka me). There is some syntax that takes getting used to, but once you figure out the gist, its a walk in the park. Theres nothing more fulfilling than working at something that seems so foreign and finally seeing it work.

The tutorial I used to setup my server were by Konstantin Kovshenin from Automattic. The lists that I found most useful are below.

Yeoman

I recently fell into the bandwagon of Yeoman. After spending time with Peepcode screencasts to deepen my understanding of jQuery, javascript and MVC frameworks, I decided TDD and Grunt were crucial to m y development process. Having people like Chris Coyer and Paul Irish on my radar made me finally fess up and get Yeoman running locally.

Getting Running

Issue with running Yeoman is initially my allergic reaction to automated terminal commands. I am not always fond of seeing foreign words run by my command line, but I try my best to understand what they are doing.

Grunt installs itself when you run Yo Webapp. Theres little you need to do to have working scaffolded application with TDD ‘infrastructure’ in place (aka Mocha, Grunt, JSLint, etc). When you follow the directions from Yeoman.io, its easy to get the web app running

Problems

I started having problems when I wanted to run Grunt server. When I ran Grunt alone, the process ran without any problems. For some reason, when I tried to test the server, Grunt would hang up on LiveReload. Specifically, I got this message:

Running "server" task

Running "clean:server" (clean) task

Running "coffee:dist" (coffee) task
>> Destination not written because compiled files were empty.

Running "compass:server" (compass) task
Nothing to compile. If you're trying to start a new project, you have left off the directory argument.
Run "compass -h" to get help.

Running "livereload-start" task
... Starting Livereload server on 35729 ...

... Uhoh. Got error listen EADDRINUSE ...

I posted a bug report to the Yeoman Github repository here and pinged sindresorhus. Within a day, another user replied on the Github issue thread explaining he had the same issue. Similarly, Sindre Sorhus also pitched in to help.

Solution

Eventually, I didn’t figure out what would solve the problem. I found a stop-gap measure which lets me continue running grunt server and have a local copy run without issues.

In Grunt.js, I needed to remove the line calling livereload-start. I did this by changing the grunt.task.run like this:

grunt.registerTask('server', function (target) {
    if (target === 'dist') {
        return grunt.task.run(['build', 'open', 'connect:dist:keepalive']);
    }

    grunt.task.run([
        'clean:server',
        'coffee:dist',
        'compass:server',
      //'livereload-start',
        'connect:livereload',
        'open',
        'watch'
    ]);
});

Reflection

Even through I had googled portions of the error code in hopes of finding someone with a similar situation, there were no people with my exact situation. As a result, I thought about updating my Gems, Command-Line Tools and various brew packages. The Github issues response time was great. I’ll keep trying to get a better understanding of how to use Yeoman. For the time being it works!

“I feel like we are dueling with lightsabers” -Spady

I wrote a paper titled “Soka Education and Digital Education Technologies: Massively Open Online Courses,” for the 2013 Soka Education Student Research Project conference. The following section is the conclusion.

Conclusion

Soka education’s philosophical framework for teaching and learning is appropriate for the emerging to the newly emerging educational technology field. This papers goal was to help draw attention to a field that is quickly emerging with good intentions. The growth and social cause makes it attractive to both educators, entrepreneurs, and investors. Having such a great impact on the students, it must be carefully traversed. In references to evidence oriented progress, Makiguchi states:

“We must strictly avoid following ideologies of uncertain origin that cannot be substantiated by actual proof-even if they may be the most time-honored tradition-and thereby sacrificing the precious lives of others and ourselves.”

The education technologies too must be scrutinized to insure they are being implemented for the correct reasons. While MOOCs and other tools may benefit schools in reducing costs and increasing profits, the fundamental question should revolve around how they improve a students learning opportunity.

The digital technologies emerging in the education space are seeking to improve student-centered learning opportunities, but the educational technology space is not new. In the past five years, investors funding emerging private educational technology enterprises has quadrupled. These investments are spurring ventures such as MOOCs, but are still building profit-seeking entities. As a result, the driving forces behind Soka education are invaluable for reflecting on the purpose of education technology companies. Traditionally disruptive technology companies must be extremely careful in their disruption of existing educational markets. While emerging digital technologies can undoubtedly offer value to improving student experiences, many systems are already healthy.

The MOOC field is targeted at student-centeredness in a way that is inline with Soka Education. Just as the MOOCs themselves are not innately good or bad, their application must be continually considered. Companies like Udacity and Coursera are already holding classes that are eligible for actual college credit in American universities. The MOOCs are will help colleges reduce the cost of classes, expand course selection for students, and continue growing the discussion on the application of digital technology to education. The digital tools redefine “student-centeredness” by allow students to personalize their learning experiences in ways less prone to budget and institutional capacity.

Future Research

Future research should further analyze the following points from the perspective of Soka education: MOOC course rights, digital resource copyright clearance, hybrid teaching pedagogies, the usage of other multimedia tools for student learning, and the efficacy of video based learning materials. These topics could each be the basis for extensive research to further the field of student-centered education using digital technologies.

“The Trial” Kafka

Starting off with the face that I needed some New York in my life. Digging the people, the architecture, the little coffee shops and busy subways.

First two chapters.

Kafka writes The Trial in a slight mysterious plot line that Im not used to reading. Reading the news and twitter streams has made me expect the core of the manner in a short burst. The Trial lays out a plot line by painting a clear picture and scene. The scene is filled with distinct emotional expression and tension, but there are no defined characters or causes. In a buddhist explanation, The Trial describes the world through effects, rather than causes.

Home invasion

The book begins with an abrupt awakening of the main character. Two men disrupt K. from his morning regime of breakfast and preparing for work. Instead, he is observed and kept from leaving his room. He is arrested.

The arrest is not explained to the reader or the main character and unfolds into the dangers of a hierarchical authority system. The figures arresting K. do not know why he is being arrested, but feel quite justified in their restriction of K.’s freedom. The invasion of privacy, disruption of personal space, and disregard for another’s humanity is seen in so many facets of society. The authority figures are not alone in their expression.

K., who hopes to reclaim his dignity, seeks answers. After being detained in his own home, he encounters the figure of higher command who personally interview the detainee. K., who continues seeking the cause for the injustices of the morning, encounters yet another response absent of reason. The invading figures freely roam K.’s home and declare their departure.

Court appearance

Forced to face his day without comprehending the complete background of the morning’s events, K. braves the rest of his day at work. Left only with a notion that he is expected to appear in court, he is forced to make assumptions as to his appearance date. Again, lacking all information to help understand the situation, K. decides to make his way to the courts on the first potential day court gathers.

Finding his way to the courthouse is no simple task. K. wanders the neighborhood and buildings near the courthouse, hoping to glimpse upon the place of his belonging. K. discovers the courthouse only too late and is forced to stand trial the moment of his arrival. Again, no explanation, he is placed in front of, what seems to be a divided courthouse.

Giving his all, K. argues for the injustices he is forced to undergo. Again, little understanding behind the disruption’s cause makes the argument one of unwarranted personal invasion.

Realm of foreign rules

Throughout K.’s series of events, the reader is left to wonder how easily the same events could happen to themselves. K. is a everyday well respected citizen. There is little that he did to provoke these events. More so, he seems to do everything in proper order to understand the dilemma, but is given no regard.

Replace K.’s story with any individual, young or old, and The Trial reflects their own experience in a judicial system. When expected to defend oneself in a realm of foreign rules, it matters little that there is any reason at all. The senselessness of the book’s plot captures closely the “in the moment” activity one is forced to experience in any mode of heavy jurisdiction.

The digestion of events is difficult in foreign systems of operation. More so, in moments of extreme consequence, the notion of clear reflection is nearly impossible.
