Coding Cults & Internet Gods

Any sufficiently advanced technology is indistinguishable from magic.
Arthur C. Clarke

Its been talked about before, but while reading the 'The God Delusion' by Richard Dawkins (and no he doesn't Twitter!), the meme of the Cargo Cult once again caught my attention.

Cargo Cult: Waiting for Frum

Anthropologists have observed the phenomenon of island inhabitants (most famously of Pacific Melanesia and New Guinea) mimicking and performing rituals of visiting advanced cultures in the belief that these acts will provide them with material goods and wealth. This phenomenon is known as a Cargo Cult.

The islanders observed that the visiting people enjoyed great luxuries, with seemingly little or no useful work required in return - they sat behind desks while new or repaired items appeared on the island as if by magic.

In one instance, on the island of Tanna in the New Hebrides (now known as Vanuata), the islanders awaited the return the messianic Mr John Frum who would bear bountiful cargo. Supposedly arriving by plane from America, the islanders cleared an airstrip and installed a bamboo control tower, replete with wooden headphones. They still await his return.

In our technologically advanced, self-actualising, networked society, cargo cults are still in full effect.

The Cult of the Internet Gods

With new social networking tools emerging on the net every day, users scrabble to adopt these applications in the hope of increasing their social network status. A case in point: Twitter. A few in the industry have risen to deified status, having built large networked tribes with thousands of followers. 'Lesser mortals' reply or re-tweet these Twitter superstars in the hope of building their visibility and profile.

The cult of the social media tool is further expounded with the concept of the invite-only period. The exclusivity built around the new network heightens user desire to be included and follow in the keystrokes of the privileged early adopters. As these tools grow and permeate, the onus is on people to opt in to these new networks - or fear missing this new source of flow information.

That being said, this phenomenon does propel the ideas and tools in that space forward, helping refine processes and opening the network for use in unexpected and innovative ways. The mass take-up of the network helps progress the tool and inevitably leads to a disruptive leap to the next social network tool.

Users also quickly determine if the tool is of real use in their daily workflows and can decide to opt out of that particular network stream.

Cargo cults with less satisfactory results can also be found in coding practices.

The Cult of Copy And Paste

At times, we need to replicate a piece of code from one code-base in another project/application. For the times when the functionality cannot be extracted out to a utility library, the temptation to simply copy the code can be strong. The application may even work as expected during testing and it appears that some time may have been saved. At some point, however, copy'n'paste karma may come calling back with problems.

Time should be taken to understand and verify what each line of the replicated code is doing. Is each line necessary? Is there a subtle change required to achieve the goals in the new code-base? Answering these questions can avoid problems and unexpected behaviour and gives the developer confidence in knowing the flow of the application.

The Cult of Scripting

Build systems and deployment scripts can sometimes be arcane pieces of dark magic - Maven still confounds me! Often written in languages that require real expertise to understand subtle nuances, developers can be left executing scripts which they know little about other than the final (hopefully successful!) result. This lack of understanding can lead to problems.

On one banking application I worked on, a set of build scripts was employed to deploy an application into the target environment - configuring the database and the application server. The development team was given little information on the intention of the scripts, with only sample scripts from another project as a guide.

New scripts were developed (copied!) and executed. However, soon after application initialisation, problems with database connections were reported and the application would need to be restarted. For each deployment, the release engineer was requested to run all the scripts. Upon further investigation into the nature of the scripts, it transpired that one of the scripts was only required to be executed once at the outset of the project, in order to configure the database and connections. Thereafter, only the application configuration scripts were required.

Build and deployment scripts can be difficult and time-consuming to deconstruct. In this respect, breaking the task into discrete parts can help, by aiming to understand small sections of the script at a time. Learning to understand the intricacies of the process can lead to resolution of issues as described above, or improvements in the overall process workflow.

So, is your code expecting the return of Mr Frum anytime soon?

Local Testing OAuth Social Signin

On some recent Grails projects, I have been looking at using the Twitter and Facebook OAuth signin process. This process allows you to authenticate users based on their Twitter/Facebook logins, without the need for the user to expose their passwords to your site. When you create your 'application' within Twitter or Facebook, it is necessary to define the URL where the application can be accessed. Twitter and Facebook will only redirect to this URL during the authentication process. I have tested running some applications on Heroku or Appfog , with Twitter and Facebook happy to redirect to the appropriate URLs with successful authentication. However, when testing locally, I follow these steps to work through the authentication process. 1. App Context Ensure that the Grails app context is '/' - as the application is generally deployed this way on Heroku/Appfog: Config.groovy = '/' 2. Port Binding: While the local application w

Brain Error: No space left on device

I'm not dumb. I just have a command of thoroughly useless information. Calvin - It's a Magical World, Bill Waterson Wired's June 2008 edition included an article entitled ' Quiet Please : how Man-made noises may be altering Earth's ecology'. The article focused on the theory put forward by Bernie Krause , a field recording scientist, that nature's soundtrack (biophony) is being adversely affected by a louder human-made cacophony (anthrophony). Krause postulates that the animal kingdom divides the acoustic spectrum so it's inhabitants do not interfere with each other. However, human-made noise is increasingly disrupting this harmony and intrudes on a piece of the spectrum already in use - drowning out natures voice. As an example, Krause summizes that the rapidly declining population of the Yosemite spadefoot toad is due to the noise generated from low-flying military aircraft, performing training exercises in the area. Coyotes and owls are able to home

Explore. Dream. Discover. Be Interesting.

Interesting 2008 Bunting and all ... Twenty years from now you will be more disappointed by the things that you didn’t do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover. Mark Twain Over the weekend, my wife and I attended Interesting 2008. The concept of the event - to gather a number of speakers to talk about something they are interested in - was intriguing and all reports suggested it would be a Saturday well spent. Comparisons with the TED talks certainly helped to pique my interest and we were most definitely not disappointed. Russell Davies , the coordinator of the day, has this to say about being 'interesting': The way to be interesting is to be interested. You’ve got to find what’s interesting in everything, you’ve got to be good at noticing things, you’ve got to be good at listening. If you find people (and things) interesting, they’ll find you inter
