Dorkbot Toronto presentations tonight

I plan to attend an interesting event in Toronto tonight - a meeting of Dorkbot-Toronto.

Dorkbot-Toronto seeks to explore all uses of technology in the development and discussion of art and creative exercise. It is meant to be an informal and collaborative environment where anyone can drop in, listen to presentations, and meet others for future collaborations. We invite people across all disciplines and skill levels to attend and explore ideas of hybridization, as well as perform open investigations into electronics and code.

Meetings are always free and open to the public.

If this sounds like your kind of event, and you are around the Toronto area tonight, I suggest you check it out.

I have added a google map perspective to this post if you need directions.

Three presenters are planned for tonight:

I’ve never been to one of these meetings before, but I suspect it will be pretty cool.

Finding the blog influentials

Matt Galloway hits on many great ideas in his post about influential bloggers.

It is quite simple: (good) bloggers = Influentials

To stay ahead of the curve:

  1. Find your blog influentials
  2. Listen
  3. Repeat step 2

Why I blog this? Now that we have this huge blogosphere to play in we need to start data mining the meta-data it generates. Information overload is my new problem - high quality information at that. I am reading over 500 feeds now. It is become overwhelming - too many blogs to remember/manage in my head. So, how exactly should I be identifying blog influentials? This I do not know. As far as I can tell, identifying blog influentials programmatically is an as-of-yet untapped area with growth potential.

How exactly do we identify blog influentials?

It is good to see that Mitch is still keeping busy playing with interesting ideas. I posted about Mitch’s RatcliffeBlog and MyDensity a couple of times (1, 2) back in March.

Physicists deepen understanding of didgeridoo acoustics

The Australian didgeridoo or yidaki is a simple wind instrument, yet a good player can coax from it a variety of timbres greater than that of many an orchestral instrument. It can produce a huge variety of different timbres, despite it usually playing only a single note. A study of the vocal tract and lip contortions necessary for this feat tells us a lot about how music is made.

To understand this phenomenon, researchers led by Joe Wolfe of the University of New South Wales in Sydney simultaneously measured the sound produced by the didgeridoo and the acoustic impedance of the player’s vocal tract. What they found was that a skilled player alters the acoustics inside their mouth to set up strong resonances at certain frequencies. Players enhances certain frequencies while inhibiting others, much as different vowel sounds are produced by adopting different positions for the tongue and vocal cords. In other words, experienced players are using their glottis to accentuate the instrument’s tonal variation.

Skilled didgeridoo players do this subconsciously, Wolfe says: “None of the players to whom we’ve spoken is aware of it.” But the creation of these characteristic frequency bands, called formants, is what gives their playing expression and variety. “It’s easy to make a basic sound,” Wolfe says. “Then you have to learn circular breathing. Learning to make strong formants takes a while. Other techniques involve vocalizing and playing at the same time: one gets interactions between the vibrations from the lips and from the vocal cords.”

Why I blog this? Over the past few months I have been learning about as much as I can take in about acoustics, synthesizers, and music in general, so this article instantly grabbed my attention. Also, a good friend of mine has been playing didg for a number of months now, and I have been able to watch the dramatic improvement in her playing skills during that time. Thus, this story about the acoustics of the didgeridoo was quite interesting to me.

iUpload blog coverage

Tags: — 10:41am

I am subscribed to a PubSub feed (that I created) to let me know when anyone in the blogosphere references iUpload. Today I noticed some new incoming links related to a recent interview that our CEO (Robin Hopper) had with Infoworld.

Thanks PubSub, for letting me find the following blogs:

Why I blog this? Because it is an excellent example of the power of the blogosphere. It did not take me any extra effort to see what people were saying about us. All of the extra meta-data that blogs generate is so incredibly valuable!

Reactive Colours and the autistic community

Reactive Colours is an innovative project that is developing software to promote enjoyment and social interaction in severely autistic children.

It is using an non-commercial open source development model, and is aiming to include the autistic and Asperger’s community as developers and contributors to the project.

Sounds great. I’ve highlighted some of Mind Hacks interview with project leader Wendy Keay-Bright.

Wendy undertook a feasibility study which strongly indicated that this therapeutic way of working with computers could have particular resonance for children on the autistic spectrum.

The design of the software prioritises the computer as a medium. The computer becomes an environment where exploration and play, which are vital in the learning process, can occur spontaneously. This contrasts with the generally accepted notion that the mouse, keyboard, screen and even programming code, are purely functional components in a system.

Many computer programmes for autistic children focus on task or making progress, and this in some cases, can lead to the feeling of failure or children can become ‘locked in’ to a task and resist communication with others.

A highly significant goal in autism education is the achievement of joint attention tunnels. With this in mind it has been encouraging to witness children share their Reactive Colours activity session (which we are calling ‘Reactivities’) with their peers in monitored classroom environments.

This has been most dramatic in a multi-sensory environment using the interactive whiteboard where children use their hands and bodies to choreograph stunning visual effects.

Multi sensory stimuli can be alarming for some children, however the Reactivities reward touch and sound with simple forms - colour, shape and words and deliberately avoids sensory overload.

High levels of anxiety are very commonly found in children on the autistic spectrum. The experience of playing with Reactivities on the computer is entirely intuitive; the reactive graphics focus on spontaneous mark-making and cause and effect.

Expressive mark-making can relieve tension and outwardly represent inner experiences. Rhythm, sound, space, velocity, colour, shape and movement are created and controlled by the individual as they experiment with the mouse, keyboard and microphone input devices. This expression of creativity is personal, unique and ultimately satisfying.

Children are content to choose and explore, take turns and co-operate with others, all of which are significant for individuals on the autistic spectrum. The capacity to have fun is an almost universal human coping mechanism for dealing with stress, however for many autistic children this vital tool for releasing energy is not realised.

From our early experience of developing Reactive Colours with young autistic children we have seen opportunities for structured and parallel play that may help to create a calm environment for participatory learning.

And a note:

Although the Reactive Colours website has not yet been officially launched, (we are aiming to do this Spring 2006 when the Reactivities have been completely iterated with users) we would encourage anyone interested in the project to post their details on the forum and visit the site regularly for updates.

Teachers, parents and advisors who would like to participate in evaluating the prototype software can email Wendy for more information.

But Reactive Colours does have a blog.

Why I blog this? I met a women on Friday night who works with two autistic children. I asked her a number of questions about how these children experience the world. I was trying to figure out how technology could help these children, or help her help these children even more than she already is. So when I stumbled across the Reactive Colours project today, I knew it made sense to make a post and pass this information on to her and all of my other readers.

We should all want, and have, real-time fuel economy gauges in our cars

Tags: — 3:26pm

I love reading about great ideas. In this case: Putting a mpg-meter, fuel economy gauge, fuel consumption feedback - call it what you want - in all cars.

One important reason why hybrid cars result in better mileage is that drivers suddenly have an indication of how various aspects of their driving habits shape mileage. Hybrid mailing lists are filled with people taking about "driver break-in periods" as new drivers, given immediate feedback from the car, learn how to drive in a mileage-optimal fashion. Most hybrid drivers see a steady improvement in mileage over the first year because of this.

There is now a 50% chance of being infected by an internet worm in just 12 minutes of being online using an unprotected, unpatched Windows PC.

Why I blog this? I find the latest reseach results on malware infections to be sad and disturbing, even a little disgusting, but not at all surprising. It is going to get worse, a lot worse, before it begins to get any better.
