Notes from BarCampRdu,Part 1: General, Session 1

Yesterday I attended BarCampRDU at the Red Hat campus in Raleigh. Fred Stutzman did a wonderful job of organizing, so everything went smoothly. I am going to take some time over the next few days to look over my notes and blog some of the ideas that I thought of during the discussions. Overall I had a great time and look forward to participating in many more unconferences in the future. It was an excellent way for the local tech community to get together. Now that I understand how unconferences work, I would like to take a more active role in either planning or in leading a talk next time round.

The first talk I went to was “Refactoring Your Wetware”:

Andy Hunt of The Pragmatic Programmers likes to talk about how your brain works. Pole-bridging, pragmatic learning, the Dreyfus model of skill acquisition, and even a little of Getting Things Done are all fair game.

While this session turned out to be more of a talk than a discussion, it was still very interesting. Andy began by setting forth the following ideas:

Using more of your brain’s horsepower!
• (experts rely on intuition) context dependent > context free (novices follow rules)
• Mastering knowledge doesn’t increase your professional effectiveness
• Problem for certification programs
• So? ->> tweak the brain
• Brain compared with computer model.
• Fast non-linear part, slow linear part but only one can access memory at any time
• 10% analytical, verbal — Geeky
• 90% irrational non-verbal – Artsy

He then went over a number of ways to get take advantage of that 90%. I feel it was a good start to the day as it got people thinking about how to look at things from different angles. Below are the notes I took. They are relatively raw. I think they are all in my own words, but a few phrases may accidently match Andy’s slides. If you get a chance to see this talk of his I would suggest going.

Thus design matters. (iPod example)
• Check out the video of Microsoft iPod – loses the design and good sense
• Drawing on the right side of the brain
• Trace an upside down image, but don’t label in your mind focus on the lines
• Default to symbol instead of reflecting on the deeper meaning

How to engage r-mode processing
• Focus on sensory experience
• Use building blocks like legos during design sessions
• Emphasize cross sensory feedback
Lozanov Séance — yoga inspired breathing and repetition in dark room with baroque music and foreign words being repeated
• “Write drunk, but revise sober”
• Start with multi-sensory learning and then follow with traditional learning
• Memory stores every input
• Right mode actually scans these memories, but it is hard to transfer the harvested memory to the left mode because it is like trying to verbalize a dream

Image streaming
1. Ask yourself a question / pose a problem
2. Close your eyes for 10 minutes
3. For each image that crosses your mind
1. Describe it outloud
2. Imaging it using all five senses
3. Source of image not as important as interpreting it – rub eyes, look at bright light first

Journaling
• Write three mages a day in longhand, uncensored, never skip a day
• Typing is very L-mode being at the keyboard is a bad place for creativity
• BOOK – A Whack on the Side of the Head.
• Seeing something from a completely different point of view causes the right mode search algorithm to kick in differently.
• Avoid mental locks - Made me think of a book I read called The Eureka Effect that discussed very similar ideas.

Magic of the “oracle”
• is to focus pattern matching by broadening scope
• This made me think of Socrates (because he was motivated by the Oracle at Delphi). Maybe he was using his right brain?

Need to keep track of great ideas or your brain gets lazy and stops worrying about it.
• Capturing good ideas. Andy uses a space pen w/ notepad, index cards
• PDA with a wiki or sticky notes, voice recorder on pda,
• My new idea talk to Bluetooth earpiece while walking home and have the call recorded to my blog.
Pocketmod.com
• Transcribe and integrate I a hyperlinked space (wikispace)

Context switching is bad and ruins productivity
• Multitasking and interruption like checking email (-10iq) worse than smoking a joint (-4iq)
• Second monitor yields productivity gains of 20%-30%

That was the end of my notes. I will post more notes and ideas later over the next few days.

Comments on “The Network Effect Multiplier, or, Metcalfe’s Flaw”

Yesterday Fred Stutzman posted about a social networking theory that he is developing. I am just going to address the central theory and then outline a couple of ideas that came to mind while reading.

Therefore, the fundamental flaw in applying Metcalfe to social technology is its inherent lack of nuance and granularity. When people join the network, they are given more options than simply connecting; the network is worth the sum of associations and actions that are allowed in the network. We must instead think of network value in terms of a network effect multiplier, as the actual value a network adds to an application is under the direct control of the application designers.

The above paragraph introduces Fred’s theory. Essentially, Metcalfe’s law applied wonderfully for binary networks, but fails to take into account the multifaceted nature of modern social networks. One of the examples Fred uses is MySpace. He points out that value is not limited to how many connections a user has but is also enhanced by the various types of interactions and actions enabled by the system.

Lately I have spent time in MySpace connecting with old friends. In so doing, I have come to appreciate the customization of MySpace over sites such as Friendster and Facebook. While this customization leads to much bad design, it also enables users to add third party flash widgets to their profiles. By adding third party services, a user can in effect build in value beyond what the sites designers intended. For example, the new service txtdrop.com allows users to build text messaging capability into their MySpace profiles. In fact, this ability to mashup applications and services is one of the key features of Web 2.0. If mashups continue to be the norm and social networking sites such as MySpace begin to offer open API’s , then any new participant could bring in or develop third party value beyond the control of the designers.

Fred’s piece also made me think of other types of networks such as Wikipedia. A user’s contribution to this service can be measured in intellectual contributions as well as through interactions and actions. I really don’t have any conclusions as to how Fred’s theory applies to these networks, but am interested to see how he applies or expands his theory accordingly.

I was also thinking about how different users of web networks often have different capabilities from one another according to their administrative privileges or user type. Might it be possible to apply Fred’s theory to how many or how few privileges users should receive?

Lastly, I though of the “paradox of choice“. At what point do added features or interactivity begin to detract from the value of a network by overwhelming the users? What is the proper balance between the number of users and the complexity of the service they are participating in? I wonder if these extremes are inversely proportional so that a massive network like MySpace could be clogged if it had both too many features and too many users, but a small network of experts might benefit from a highly complex feature set. Fred’s theory might be a good starting place to explore these questions.

I am now going to read over Fred’s theory a few more times to make sure my comments are on track. If not, these are still ideas inspired by his paper.
